Description

Device for adapting a shoe sole to the outer contour of a human foot

The present invention relates to a device for adapting a shoe sole to the outer contour of a human foot, in particular with a tensioning and / or stretching device which integrates an elastic portion of the sole and is effective for widening or narrowing the shoe sole transversely to its longitudinal extent the inserted into the shoe sole or molded clamping and / or stretching device has at least two clamping and / or stretching elements, which are variable by means of at least one adjustable spacer in their distance from one another.

High quality shoes are generally expected to have a great fit. It is therefore known that handcrafted footwear that is precisely adapted to the foot of the shoe wearer and the shoe wearer is far superior to the usual ready-made footwear. For reasons of cost, ready-to-wear shoes are nevertheless preferred on a large scale. The most stressed parts of the human foot are the arch of the foot and the toes. This is particularly true for shoes that have a high heel, especially of course women's shoes with thin and very high heels. Here, above all, the front part of the foot is affected by the stress on the skeleton and the supporting organs of the toe part caused by the extreme inclination, which initially results in pain and after a long time also irreversible Deformations of the skeleton expresses.

Although a postoperative shoe is already known from the German utility model DE 8433834, in which the outsole can optionally be fitted on its foot receiving side above the sole via fastening elements, the sole has side-specific correction elements in the form of loops or plates for the toes in the forefoot area , After orthopedic surgeries, such shoes should gradually get the patient used to wearing their normal footwear and allow them to stand up and walk comfortably and painless until then. The correction devices are externally and laterally attached to the shoe and consist essentially of interconnectable bands or loops. For normal footwear such orthopedic aids are useless.

The finished shoe, in particular the ready-to-wear shoe, can only be adapted to the wearer's foot to a minimum extent for a long time in its dimensions with a high degree of effort through mechanical expansion or patient wear. This usually succeeds only inadequately and also often in pain and using visually unattractive measures.

From US 2006/0162191 A1 a sports shoe with an adjusting device for the shoe width is known, in which a sole has at least one screw, which cooperates with a corresponding insert, wherein the screw has a head, a cylindrical portion and a threaded end and wherein a flange is formed at a short distance from the head and a flange is in correspondence with the end of the thread. The insert has a correspondingly large volume to accommodate the adjustment forces and considerably reduces the elasticity of the sole. US Pat. No. 5,729,912 A discloses an article of footwear with an adjustable width, foot shape and cushioning, in which a U-shaped hollow chamber is provided and at least two earth rods are guided through the midsole, each at its center at an anchor on the midsole Sole are set with the ends of the threaded rods are arranged in female bolts, by turning the bolt, the distance of the armature can be adjusted from the lateral midsole at four independent points. The great variability of Einsteilmöglichkeiten naturally increases the risk of adjusting a unfavorable from the medical point of view shoe shape.

From DE 73629 A footwear with adjustable width is known, in which a sole can be widened or narrowed by nuts are attached to the two pieces of the m split length, through which by means of a spindle to be screwed or screwed off the two sole parts be pulled apart or pulled together and the footwear is made wider or narrower, the spindle is formed at one end with a screw thread and square at the other end. The forces introduced via the nuts on the sole material can cause premature wear of the sole material.

The present invention is therefore based on the object to provide finished footwear, especially women's shoes with high heels, with an inconspicuous and comfortable to operate device that allows the already finished shoe, especially in the most stressed part of the toe bale the orthopedic Needs and the needs of the wearer.

The achievement of this object is the features of the valid claim 1. The shoe according to the invention has a tensioning and / or stretching device, which is integrated in an elastic portion of the sole. To be able to spread or narrow the shoe sole if required, this tensioning and / or stretching device is effective transversely to the longitudinal extent of the sole of the foot. Since the adjustments made with the aid of the tensioning and / or stretching device are reversible, the shoe can, if necessary, be adapted to the current personal needs, so that, for example, in the case of edematous swellings, the contact width in the inner boot is increased and returned to its normal size after the swelling has subsided can be. The users of the shoes equipped with the device according to the invention can adjust these as well as the well-being requires. In addition, orthopedic measures are very easy to perform with the device according to the invention, without this being externally easily recognizable.

According to the invention, it is provided that at least two elongated sole anchors are arranged in the front foot region of the shoe sole, that the elongated sole anchors are oriented along the longitudinal direction of the shoe, that the tensioning and / or stretching device comprises an adjustable spacer, that the adjustable spacer between the sole anchors is arranged that with the adjustable spacer, the at least two elongated sole anchors in their remote from the toe end portions with pressure and / or train are acted transversely to the longitudinal direction of the shoe and that the sole width is variable by the application. The sole anchors thus each form an elongated, for example rod-shaped or flattened, tensioning and / or expansion element with which the pressure or tensile force introduced by the spacer is made uniform over a larger area of the sole is transmitted. The front foot region of the shoe preferably comprises the region up to the arch of the foot and in particular the region of the forefoot loading zone. By aligning the sole anchors approximately longitudinally to the longitudinal direction of the shoe, it is advantageously achieved that movement of the sole anchors toward or away from one another causes a change in the shoe width in the region of the sole anchors which, apart from the change in width, preserves the functional and aesthetic shape of the shoe.

The provided for tightening or stretching of the tensioning and / or expansion elements spacers of the shoe according to the invention comprises in one embodiment of the invention, a transmission having at least one stage with reduction gear, wherein the transmission is assigned a drive shaft with a tool-free manually operable actuator. At this adjusting element, the shoe wearer can adjust the shoe in its width as needed at any time to personal needs, the adjustment process is significantly facilitated by the reduction gear. The gearbox of the spacer also has at least one output shaft which is also inserted or molded into the shoe sole at an angle to the drive shaft and connected to a threaded rod which carries an external thread on at least one of its rod ends which fits into the complementary internal thread of an adjacent clamping and / or or expansion element is screwed. Thus, a rotational movement exerted on the actuating element via the drive shaft is transmitted to the output shaft of the transmission in such a way that the threaded rod connected to the output shaft changes the tensioning and / or expansion element in its relative position in the shoe sole as desired. As a result of this change in position of the at least one tensioning and / or expansion element, the sole of the shoe is preferably slightly stretched or widened only in its upper plateau portion, so that it also envelops the foot or wearing Schuhtexle experienced a noticeable, if necessary, but also reversible widening or narrowing transverse to the longitudinal extent of the shoe.

The device according to the invention can have the greatest possible effect if the tensioning and / or stretching device is arranged and / or effective in the partial region of the shoe sole carrying the toe joints of the foot.

In order to perform the adjusting movement at least in one direction with a lower force, and to return the shoe sole to its original shape, it is advantageous if the tensioning and / or stretching device is reversibly adjustable against a restoring force.

In this case, a preferred embodiment, which is associated with a low design and manufacturing effort, before, that the clamping and / or stretching device is adjustable against the restoring force of the elastic sole material.

In an advantageous embodiment it can be provided that the spacer has at least one threaded rod. Thus, an adjusting movement acting on the adjustable spacer can be transferred into a sliding movement of the sole anchors or of a tensioning and / or stretching element. The at least one threaded rod acts like a primitive transmission. The advantage here is that the adjusting movement can be performed in a confined space, for example by turning a tool introduced through a bore, and that therefore the device according to the invention for adapting a shoe sole from outside as completely as possible is hidden in the sole. Thus, the orthopedic shoe is not recognizable as such, but can vielmahr be designed according to fashionable points of view. It can be provided that the sole-anchors are fixed at their ends facing the shoe to the sole, for example by a positive, non-positive and / or material connection. The advantage here is that thus the expansion movement on the shoe sole is even more dimensionally transferable.

A shoe sole which is wide in its outset shape can be pulled together with the aid of the device provided according to the invention in such a way that the shoe sole and with it the shoe have a lower sole width perceived as pleasant. By contrast, a shoe sole which is narrow in its initial shape can be widened with the aid of the device provided according to the invention in such a way that the shoe sole has a sufficient and currently perceived as comfortable width. It is therefore expedient if the sole can be broadened or contracted by means of the tensioning and / or stretching device.

An advantageous embodiment of the invention is that the tensioning and / or stretching device has at least one tensioning and / or expansion element, for example, a sole anchor, which is associated with at least one eccentric or the like spacers.

In this case, a preferred embodiment consists in that the tensioning and / or stretching device has at least two tensioning and / or stretching elements, which are variable in their distance from one another with the aid of at least one adjustable spacer.

Such a tensioning and / or stretching device allows a purely mechanical and correspondingly permanent or, if desired, reversible shape adaptation of the shoe sole. In order to be able to transmit the forces exerted by the tensioning and / or stretching device on the shoe sole well on the shoe sole, it is advantageous if the tensioning or stretching elements and / or at least one of the spacers m are inserted or molded into the shoe sole.

The purely mechanical and correspondingly permanent and also reversible shape adaptation of the shoe sole can be achieved particularly easily if the spacer has a gearbox with a drive shaft, this drive shaft being connected to an actuating element. As a transmission is advantageously a gear transmission, such as a bevel gear, worm gear or other angular gear, or a transmission with non-uniform translation, for example, with an eccentric, which acts on a linkage usable. Through the use of a transmission, the adjustment of the clamping or expansion elements is particularly precisely controlled, especially manually.

If the transmission comprises an eccentric whose axis is connected to the adjusting element, a simple adjustment of the tensioning or expansion elements can be achieved in that the spacer has at least one adjusting rod, preferably two adjusting rods, which has at least one clamping rod. or expansion element is or are connected and the one or the axially displaceable by the eccentric or are. Due to the eccentric shape of the eccentric namely the introduced via the actuator rotary motion can be converted into a linear movement. With appropriate design of the eccentric of the spacer is even self-locking, so the material of the shoe sole can not undo an expansion.

A particularly simple, uniformly adjustable and structurally simple embodiment provides that the Standhalter has at least one threaded rod, which carries at its two rod ends opposite external thread and that these external threads are screwed into complementary internal thread on the adjacent clamping and / or expansion elements. This threaded rod can be adjusted for example by means of an externally accessible tool engagement surface which is provided on at least one rod end or in the course of the threaded rod on the rod circumference, for example centrally. However, this threaded rod can also be actuated by a control element with a gear, for example an angular gear, that is to say a gear with an input and output shaft which is at an angle to one another. In this case, by means of the external thread in the threaded rod and the gearbox, a rotational movement of the adjusting drive m is converted into a linear movement of the clamping or expansion elements. Advantageously, a self-locking worm gear can be used.

It is particularly favorable if the spacer has two threaded rods which carry external threads of equal size at their respective outer rod ends, wherein these external threads are screwed into m complementary internal threads on the adjacent clamping and / or expansion elements. Preferably, then the two threaded rods are aligned parallel and / or in alignment. In this case, the transmission can be arranged to save space between the two threaded rod ends.

Overall, a good dosage of manual adjustment in a small footprint of the clamping or expansion element can be achieved when the transmission with a drive shaft and at least one standing at an angle to the drive shaft output shaft m the shoe sole is inserted or molded, wherein the drive shaft with an actuating element and the at least one output shaft is connected to a threaded rod. If a second threaded rod is provided, then this is preferably connected to a further output shaft of the transmission connected. Due to the angled arrangement of the shafts, the actuator can be arranged transversely to the direction of expansion, which makes it more accessible.

In an advantageous embodiment, a first toothing part is arranged on the drive shaft of the transmission, that meshes with two second toothing parts, and that in each case a second toothed part is arranged on an output shaft. Thus, a uniform, manual adjustment of two clamping or stretching elements is advantageously achievable.

The transmission preferably comprises at least one crown gear stage or a bevel gear stage or another angular gear stage. Particularly favorable adjustment properties arise when the teeth of at least one gear stage of the transmission is designed as a reduction gear or reduction gear teeth.

In a further embodiment of the invention, the transmission comprises at least one worm wheel. This has the advantage of being self-locking. Thus, means for securing the adjusted position are dispensable. The device is thus executable with low weight.

It is particularly favorable if the actuating element is displaceable or movable or transferable in the axial direction of the drive shaft of the transmission between a position arresting the transmission and a position releasing the transmission. Thus, with an actuator two functions can be realized: First, the adjustment of the spacer, on the other hand, the backup of the set spacer.

In one embodiment of the invention can be provided that the actuator by a shift in the axial Direction of the drive shaft and a subsequent screwing movement about this direction from the releasing position into the arresting position can be transferred. For example, by moving in the axial direction, a thread on the adjusting element is brought into engagement with a matching thread in a housing part, and then the adjusting element is transferred by the interlocking threads m the locking position. The threads in this case preferably prevent an automatic release from the arresting position. By the initial displacement, an attack surface, such as a crown or thumbwheel, is more easily accessible in a releasing position farther from the shoe sole and a manual operation. At the same time, the locking position prevents the ingress of water and dirt into the adjusting mechanism. For this purpose, a preferably O-shaped sealing ring or a gasket is inserted in the housing or plugged onto the drive shaft or arranged on the actuator or arranged in any other way between the housing and drive shaft and m arretierender position sealingly effective.

An implementation of the invention provides that the first toothed part has a conical axial region and an axial region with spur gear toothing and that the first toothing part can be axially displaced via the adjusting element, with the axial region with helical toothing and in the gearbox releasing the gearbox arresting position of the conical axial region is engaged with at least one second toothing part. By moving the adjusting element into the arresting position, a region of larger diameter of the first toothing part is thus brought into the tooth engagement region of the second toothing part or of the second toothing point. This results in an axial load on the second toothing parts. As a result of this axial loading, the second toothing location is pressed onto a bearing surface on the inner wall of the gear housing. The resulting static friction thus secures the spacer against self-adjusting.

According to one embodiment of the invention, it may be provided that the conical axial region is conically thickened on the side opposite the adjusting element and that the position of the conical axial region arresting the transmission presses the at least one second toothed setting against a bearing surface of the housing of the transmission. Thus, by a pulling movement of the adjusting element, the at least one toothing adjustment, preferably both toothing parts, are displaced by the conical thickening and locked in a force-locking or even form-fitting manner. The gearbox and in particular the spacer can thus no longer automatically adjust unintentionally.

According to one embodiment of the invention, it may be provided that the conical axial region is conically tapered on the side opposite the actuating element and that the conical axial region arresting the transmission is pressed and clamped in a preferably circular recess of the housing of the transmission. This recess may be formed for example as a bore. The diameter of the bore is preferably dimensioned so that the first toothed part is free when a first, thinner, portion of the conical axial region is arranged in the bore, and that the first toothing is locked non-positively or even positively by the housing, if a second , Thicker portion of the conical axial region is disposed in the bore. In general, the adjusting element can preferably be transferred from the arresting to the releasing position by a pulling movement or by a combined screw-pull movement, so that the releasing position of the actuating means for the spacer, such as knurling wheels or the like, protrude further away from the shoe and are thus better graspable.

According to a further proposal according to the invention it is provided that the spacer has at least one eccentric rotatably mounted in the sole of the shoe. Depending on the rotational position of this eccentric, the distance between the tensioning and stretching elements and thus the width of the shoe sole can be changed.

An individual adjustment and adjustment of the shoe sole is facilitated if each tensioning and / or expansion element is assigned in each case at least one eccentric.

For a rotatable and stationary mounting of the eccentric m of the shoe sole is ensured, it is advantageous if the pairwise associated eccentric are held by means of a support member against each other at a distance.

Depending on the rotational position, the eccentric rotatably mounted in the sole of the shoe can exert such a pressure on the sole material that, for example, the tensioning and / or stretching elements arranged in the lateral region of the shoe sole counteract the inherent elasticity of the sole material with widening of the shoe sole be moved outside. However, an embodiment in which at least one eccentric acts on at least one tensioning and / or expanding element is preferred. In order to be able to transmit the tensile or compressive forces exerted on the sole material by the tensioning and / or stretching device provided according to the invention, it is advantageous if each tensioning and / or stretching element has an inserted or molded into the shoe sole and preferably a bar. mig trained soled anchor has.

A comfortable adaptation of the shoe sole is favored if each rod-shaped or elongated sole anchor has a curved shaping, which is preferably adapted to the adjacent side line of the shoe sole, in longitudinal extension.

In order to not only selectively widen or narrow the shoe sole, it is advantageous if each rod-shaped sole anchor is oriented in the longitudinal direction of the shoe sole. Thus, the forces exerted by the inventively provided tensioning and / or stretching device forces are transmitted to a larger area of the shoe sole.

A further embodiment according to the invention provides that the tensioning and / or stretching device has a horseshoe-shaped tensioning and / or stretching element, which is variable in its length, in the shoe sole. In this case, an embodiment is preferred in which the free ends of the tensioning and / or expansion element m of the shoe sole are held stationary.

In order to lengthen or shorten the horseshoe-shaped tensioning and / or expansion element of such a tensioning and / or stretching device as needed m its length, it is advantageous if the tensioning and / or expansion element has at least two sub-areas, via a common Winding device are interconnected. By winding the adjacent portions of the clamping and / or expansion element of this clamping and / or expansion element can be shortened if necessary. Who- the adjacent subregions unwound from this common winding device again, the tensioning and / or expansion element can be increased such that it can exert appropriate pressure forces on the surrounding sole material and widen the shoe sole accordingly.

In this case, a preferred embodiment according to the invention that the tensioning and / or expansion element is designed as a rope.

Em other proposal according to the invention provides that the spacer has at least two, m opposite directions axially displaceably guided pressure elements which have an inclined surface on their facing pressure element sides that the pressure elements with their side facing away from the inclined surface pressure element side a clamping - And / or expansion element act upon, and that transversely to the pressure elements, an adjusting element m the shoe sole is movably guided and fixed, which on its Druckele- the elements facing side has bevels, which act on these inclined surfaces of the pressure elements such that an axial movement of the actuating element m oppositely oriented sliding movements of the tensioning and / or expansion elements acting on pressure elements can be implemented. In this embodiment, which allows a precise change in shape of the shoe sole, axial movement of the adjusting element can be converted into smooth sliding movements of the clamping and / or stretching elements movable in the opposite directions.

In order to favor a precise change of the clamping and / or stretching device provided according to the invention as well as a precise adaptation of the shape of the shoe sole, it is advantageous if the adjusting element carries an external thread which is used to move and fix the adjusting element in an inch of the shoe. sole is fixed screwed internal thread is screwed.

It is advantageous if the pressure elements and / or their associated control element are designed rod-shaped.

A simple adjustment and adjustment of the shoe sole using the inventively provided tightening and / or stretching device is facilitated if the spacer from the top, the bottom and / or at least one narrow side and / or of the tread of the outsole for

Heel is limited from adjustable side of the shoe sole.

According to one embodiment of the invention, it can be provided that the shoe is a high-heeled heel shoe, in particular women's shoe, that the shoe sole between the front foot area and the heel has an angled surface opposite the tread and that the spacer and / or the adjusting element by an in this area preferably centrally disposed opening can be actuated. The advantage here is that in the position of use on the foot hidden from the outside underside of the sole in the area of the support of the arch of the foot contain a passage for actuating means of the spacer. The device provided for orthopedic reasons is therefore on

Shoe not easily recognizable.

Preferably, a transmission actuated by the actuating means is embedded in the sole, in particular in an area of the sole outside and behind the forefoot loading zone. Thus, the transmission is not noticeable from the supporting foot because it is located outside the forefoot loading zone. The fact that the transmission is concealed in the concavity of the shoe sole, on the one hand, the transmission from damage while running and damage by the Body weight protected and second the foot under load is not hampered or impaired by the volume of the transmission.

According to one embodiment of the invention, it can be provided that at least one sole anchor, preferably both sole anchors, at its / their ends facing away from the spacer end / ends carries a nose or thickening / wear and that the / the sole anchor fixed with this nose or thickening in the sole material is / are. In this way, a particularly effective form-fitting connection between sole anchor and sole is formed, by which the deformation of the sole width adjustment is effected.

In order to improve the comfort of the shoe equipped with the device according to the invention and at the same time to achieve a punctual reduction in pressure, it is advantageous if the shoe sole has a hollow chamber in its part area assigned to the metatarsal bones of the second, third and / or fourth toe having soft elastic material area or the like upholstery.

Carrying comfort can be improved even further if the shoe sole has a sole raising intended for supporting the front transverse arch of the foot. For the same purpose, the shoe sole can additionally or instead also have a support for the medial foot longitudinal arch.

A pressure reduction can also be achieved if the shoe sole is associated with at least one gel pad or similar pad for reducing pressure in the region of the heel strike and / or the metatarsophalangeal joint.

The on the inventively equipped shoe sole located Lean foot is particularly well and comfortably supported when the shoe sole is assigned to a preferably under the insole introduced outer and / or inner edge elevation and / or a Mittelfußabrollsohle.

1 shows an "X-ray view" of a shoe sole 1 which is part of a shoe 2 designed in more detail as shown in FIG. 2 as a men's shoe 1 has a device for adapting the shoe sole 1 to the outer contour of a human foot, which comprises a tensioning and / or stretching device 3. This tensioning and / or stretching device 3 is integrated in an elastic portion of the sole 1 and effective for widening or narrowing the shoe sole 1 transverse to its longitudinal extent.

In Fig. 1 it can be seen that the tensioning and / or stretching device 3 is arranged and effective in the portion of the sole 1 supporting the toe joints of the foot. The shoe sole 1 is made of elastic material at least in this partial area. The tensioning and / or stretching device 3 is adjustable against the restoring force of the elastic sole material. In this case, a wide shoe sole 1 can be pulled together with the help of the tensioning and / or stretching device 3 to a perceived as pleasant, reduced sole width. Instead, it is also possible to widen a narrow shoe sole 1 with the help of the tensioning and / or stretching device 3 to the individually required sole width.

From a comparison of Figs. 1 and 3 it is clear that the tensioning and / or stretching device 3 has two clamping and / or expansion elements or Sohlenanker 4, which are mutually variable by means of at least one adjustable spacer 5 in their distance. This spacer 5 has a threaded rod 6, which carries opposite external thread at its two rod ends. These external threads are screwed into complementary internal threads on the adjacent clamping and / or expansion elements or sole armature 4.

Each of these tensioning and / or expansion elements or sole anchor 4 has a rod-shaped sole longitudinally oriented sole anchor 7, which is formed in the sole material of the shoe sole 1 and can transmit the forces exerted by the spacer 5 forces on the shoe sole 1. Of Furthermore, each tensioning and / or expansion element or sole anchor 4 has a threaded sleeve 8 carrying the internal thread, which is connected in a form-fitting manner to its associated adjacent anchor 7. Between the opposite threaded portions of the threaded rod 6, a tool engagement surface 9 is provided, on which the rotatably mounted in the shoe sole 1 threaded rod 6 can be rotated if necessary in one or the other direction. Additionally or alternatively, a tool engagement surface, for example a hexagon socket, can be provided on at least one front end of the threaded rod 6, which is accessible from the sole edge.

The incorporated into the shoe sole 1 device is shown in Fig. 3 in more detail. The tensioning and / or stretching elements or sole anchors 4 of this device have the approximately horseshoe-shaped mounted sole link 7, which are movable inwardly and outwardly by means of the rotatably mounted, equipped with opposite threaded portions and guided by the threaded sleeves 8 threaded rod 6. The threaded rod 6 is embedded in an elastic, preferably made of tissue-compatible rubber or plastic material shoe sole 1 so that the rod ends of this threaded rod 6 are accessible from the lateral edge of the sole forth and thus adjustable with a suitable tool from the outside. The sole anchors 7 are fixed in their front part by means of a fastening at least on the elastic sole portion, but better in addition to an underlying and not necessarily very elastic sole portion, so that the maximum of the integrated into the shoe sole 1 tensioning and / or stretching device 3 achievable adjustment is achieved approximately in the area of the toe joints of the foot, while in the front part of the shoe, so practically in front of the toes, no adjustment takes place. From Fig. 2 it is clear that the equipped with the shoe sole 1 ladies shoe 10 can also be configured relatively high-heeled. In FIG. 2, the position of the sole anchors 7 is indicated and the opening 11 is visible for the tool engagement surface provided at the bar end of the threaded rod 6. The adjustment of the threaded rod 6 can of course be done with all the usual tools for such devices, such as screwdrivers, matching nuts or Allen key inside. If it allows the design of the shoe, it is also possible to move the adjustment via a detour linkage to a point of the outsole, which, if appropriate design, for example, by a small hidden wing nut or lever, tools can be completely dispensed with.

In the "X-ray view" according to FIG. 1, an overlying insole is shown beyond the tensioning and / or stretching device 3, which forms the usual formations for an orthopedic footbed, in particular for supporting the toe part and, as a lateral support, also elevations For insoles, it has been found useful to firmly bond the underlying elastic sole portion to the insole at preferably several points of connection, this being possible because most insertion soles have sufficient elasticity to only reach in the mm range It is particularly favorable, however, to ensure that particularly elastic insoles are used, or, even better, that the particular shape of the footbed is already in unity with the elastic sole, which the tensioning and / or stretching device 3 includes provide. Since the spacer is adjustable from the top, the bottom and / or the side edge of the shoe sole 1, the tensioning and / or stretching device 3 is not perceived as a foreign body and is not from the outside further visible.

FIG. 4 shows a shoe sole 1 with a tensioning and / or stretching device 3, the essential components of which correspond to the tensioning and / or stretching device 3 from FIGS. 1 to 3. Also, the tensioning and / or stretching device 3 shown in Fig. 4 has two, arranged on opposite sides of the shoe sole 1 clamping and / or expansion elements or sole anchor 4, wherein the distance between these clamping and / or expansion elements or Sohlenankern 4 with Help a spacer 5 is changeable. This spacer 5 also has a, in the shoe sole rotatably mounted threaded rod 6, which has opposite threaded portions at its two rod ends. These threaded portions are screwed with their external thread m one, in the shoe sole 1 displaceably guided threaded sleeve 8 of the clamping and / or expansion elements or Sohlenanker 4, which convert the rotational movement of the threaded rod 6 in an axial movement and open an adjacent Sohlenanker 7. The force exerted by the threaded rod 6 force is transmitted to the sole rod 7, so that an elastic, preferably made of tissue-compatible rubber or Kunststoffmateπal basic body or soft tissue component in the shoe sole 1 is apart or compressed. The threaded rod 6 is selectively accessible from the outer or inner region of the shoe sole 1 and thus adjustable. The sole anchors 7 are fixed in their front portion with a fastening, so that in the front part of the shoe sole, ie at the level of the end members of the toes, a lower adjustment, while the maximum of the adjustment is achieved at the level of the toe joints by a sliding hole, which may be provided, for example, in the rear region of the sole anchor 7. The users of the equipped with the tensioning and / or stretching device 3 shoes can this So adjust your shoes exactly as your personal wellbeing requires. If the feet are swollen in high summer temperatures or after prolonged standing, the shoe can be adapted to the respective space requirements. Likewise, anatomical features are compensated by the tensioning and / or stretching device 3. In the case of edema, temperature or pressure-related swelling of the foot, the sole support width in the inner shoe can thus be increased and, after the swelling has dropped, be reset again. Tight feelings in the forefoot area caused by the decay of the longitudinal arch of the foot can be adjusted individually and optimally - separately for each foot.

FIG. 5 illustrates a further embodiment of a tensioning and / or stretching device 3. The tensioning and / or stretching device shown in FIG. 5 also has two tensioning and / or stretching elements or sole anchors 4 arranged on opposite sides of the shoe sole 1, the spacing of which can be adjusted with the aid of a spacer 5. This spacer 5 has two, in opposite directions axially displaceably guided pressure elements 12, which each have an inclined surface 13 at their mutually facing pressure element sides. These pressure elements 12 act with their side facing away from the inclined surface 13 pressure element side an adjacent clamping and / or expansion element 4. The spacer 5 of the tensioning and / or stretching device 3 has an actuating element 14, which is transverse to the pressure elements 12 in the shoe sole. 1 is guided movable and fixable. This actuator 14 has on its side facing the pressure elements 12 side slopes 15, which act on the inclined surfaces 13 of the pressure elements 12 such that an axial movement of the actuating element 14 in oppositely oriented sliding movements of the clamping and / or Strain elements 4 acting pressure elements 12 can be implemented.

In Fig. 5 it can be seen that the adjusting element 14 carries an outer walls, which is screwed for moving and fixing the adjusting element 14 in a fixedly arranged in the shoe sole internal thread. In this case, the adjusting element 14, as well as the pressure elements 12, designed rod-shaped. In the tensioning and / or stretching device 3 shown in FIG. 5, the force transmission takes place according to the principle of the inclined plane by displacing or compressing the lateral direction displaceable pressure elements 12. The force is from the arrow-shaped actuating element 14 in the area of its counter-bevels 15 transferred to the pressure elements 12, wherein the adjusting element 14 serving as an abutment internal thread is arranged in the lower portion of the shoe sole.

The tensioning and / or stretching device 3 shown in FIG. 6, which is likewise integrated in an elastic portion of a shoe sole 1, has two eccentric 16 rotatably mounted on the sole of the shoe, each one on the sides of the eccentric facing the outside of the shoe sole arranged applied tensioning and / or expansion element or sole armature 4. As is clear from FIG. 6, each eccentric 16 is assigned to each tensioning and / or expansion element or sole anchor 4. The rotatably mounted in the shoe sole 1 and mutually paired eccentric 16 are held by means of a support member 17 against each other at a distance, which acts on the eccentric 16 on the clamping and / or expansion elements or sole armature 4 side facing away. By a rotational movement on at least one of the two eccentric 16, the sole anchor 7 of the associated tensioning and / or expansion element or sole anchor 4 can be pressurized such that the shoe sole 1 in this elastic portion can be widened if necessary against the inherent elasticity of the sole material. In the tensioning and / or stretching device 3 shown in FIG. 6, the force transmission thus takes place by em- or unscrewing at least one of the eccentric 16 mounted in an elastic soft-tissue body of the shoe sole 1, these eccentrics 16 bearing against the sole anchors 7 of the tensioning and / or or stretching elements rotate.

FIG. 7 shows a further embodiment of a tensioning and / or stretching device 3 that can be integrated into a shoe sole 1. The tensioning and / or stretching device 3 according to FIG. 7 has a horseshoe-shaped tensioning and / or expanding element 18, which can be changed in its length in the shoe sole 1. In this case, the free ends of the tensioning and / or expansion element, preferably designed as a rope, 18 m of the shoe sole 1 are held stationary. The tensioning and / or expansion element 18 has two partial regions 19, 20, which are connected to one another via a common winding device 21. By rotating a m of the shoe sole 1 rotatably mounted winding drum of the winding device 21, the adjacent ends of the portions 19, 20 are rolled onto the winding drum, so that shortens the length of the clamping and / or expansion element. By a rotational movement of the winding device 21 in the opposite direction of rotation, the adjacent ends of the partial regions 19, 20 can be unrolled from the winding drum so that the tensioning and / or stretching element 18 has a greater effective length. While the elastic sole material of the shoe sole 1 can be compressed in such a way that the sole width of the shoe sole 1 is reduced by a shortening of the tensioning and / or stretching element, the original sole width of the tensioning and / or expansion element 18 is larger sole width achievable. The rope-shaped tensioning and / or stretching element 18 of the tensioning and / or stretching device 3 shown in FIG. 7 can be tensioned and relaxed in such a way that an elastic, preferably fabric, with the aid of the counter-rotating winding device which can be locked in different rotational positions - Made compatible rubber or plastic material basic body or soft tissue component of the shoe sole 3 apart or compressed. The ends of the horseshoe-shaped tensioning and / or expanding element 18 guided in the shoe sole 3 are fixed in the front portion of the shoe sole 3 by means of a fastening, so that the maximum of the adjustment is achieved at the level of the toe joints, while in the front portion of the shoe sole , so at the level of the toe of the toes, a lower position takes place.

In Fig. 8, a tensioning and / or stretching device 3 is shown, which is associated with a particularly low design and manufacturing effort. The tensioning and / or stretching device 3 shown in FIG. 8 and likewise integrated into a shoe sole 3 has an expandable pressure chamber 22 whose pressure chamber volume can be changed by means of a fluid which can be introduced into the pressure chamber and / or removed from the pressure chamber. The ease of use of this clamping and / or stretching device 3 as shown in FIG. 8 still favors when air is used as the fluid, which can be pumped via a valve 23 into the pressure chamber 22 or discharged from the pressure chamber 22 again. The m of the shoe sole 1 centrally disposed pressure chamber 22 can be actuated via the valve 23. About this valve 23, the pressure chamber can be filled with a gaseous medium and / or with a liquid and transmits the force on the elastic portion of the shoe sole 1. The pressure chamber 22 is constructed such that here too the maximum of the adjustment at the level of the toe joints achieved, while rend in the front part of the shoe, so at the level of the end members of the toe, a lower adjustment takes place.

Wearing high-heeled women's shoes in particular demands a lot from the user's feet and skeletal frame. It is not without reason that a number of stars inject painkillers into the balls of their toes before stepping on the red carpet with "high heels." Many women even manage to wear high heels for a short time due to painful feet - others even have to do without No wonder considering wearing high-heel shoes for women with healthy feet: 90% of the pressure load is on the forefoot, especially on the metatarsophalangeal joint, and unilateral loading causes pain in the foot and, depending on the frequency of wear, consequential damage due to incorrect loading in the ascending skeletal apparatus.

An individual manual post-processing with individual orthopedic shoe straightening is subsequently always recognizable and thus comes at the expense of the elegance of the shoe. In addition, many walking and standing aids in retrospect can no longer be inserted into existing footwear. Especially because in high-quality women's shoes, the look for the shoe purchase is usually crucial and many women deliberately wear uncomfortable shoes to be "beautiful and sexy", they also take the health consequences with m purchase - a shoe that you As an outsider could immediately recognize as footwear processed orthopedic technology, few would wear women with the same pleasure as a visually appealing shoe.

FIGS. 9 to 15 show how medically-documented measures for improving the pressure distribution in the Shoe and to increase the comfort already in the machine production in the shoe can be introduced, which are not recognizable for untrained eyes as such. It is important that this shoe finish brings the desired relief to the majority of feet, without being tailored to specific clinical pictures. It is all about improving the comfort and comfort of shoes while reducing pressure at one point.

FIGS. 9 to 12 show a high-heeled lady shoe 2 in different views, this lady shoe 2 having the shoe sole 1 shown in more detail in FIGS. 13 to 15. It can be clearly seen that the shoe sole 1 has a basic body made of, for example, carbon fiber, which at the foot end carries a base body soft part 2 consisting of a softer, rubber-elastic material. In this basic soft tissue part 2, the above-described tensioning and / or stretching device 3 is integrated. In order to improve the pressure distribution in the shoe 2 and to increase the wearing comfort, the shoe sole has 1 m, the metatarsal of the second, third and fourth toe associated portion a, not shown here hollow chamber, which keeps away from this metatarsal bone a compressive load. In addition, a particular intended for supporting the Fuß-transverse arch sole-elevation 25 is provided. The shoe sole 1 further has a support for the medial foot longitudinal arch. For pressure reduction in the area of the heel and the large or Klemzehengrundgelenkes gel pad 26, 27, 28 are provided, which m the shoe sole 1 are embedded. If required, the tread stability can be increased by an outer or inner edge elevation introduced under the insole 30, optionally also in combination with a metatarsal sole. The many years of medical experience and operational flow Knowledge as Orthopaedist of Dr. Ing. Tree in the development.

A base soft component 29 provided for soft bedding of the metatarsal bones can be clearly seen in FIGS. 9 to 15. The hollow laying and soft bedding of the metatarsal bones and the special sole shape of the shoe 2 shown in FIGS. 9 to 15 aim at reducing pain and increasing the wearing comfort by shifting back the natural contact pressure to the large or small toe basic joint. By introducing a retrocapital support for pressure displacement and by deriving the pressure load away from the metatarsal heads II, III and IV, the anterior transverse arch of the foot is raised. The special GeI cushions dampen the heel strike and the points of entry in the forefoot area. By positioned under the insole 30 outside or Innenranderhöhung a natural orientation of the skeletal apparatus is favored and counteracted by higher heels malpositions counteracted. The Mittelfußabrollsohle should facilitate rotational movements and provide relief of the ankle and knee joint.

FIG. 16 shows a further exemplary embodiment of a tensioning and adjusting device according to the invention.

19 shows an "X-ray view" of a shoe sole 1, which is a component of a high-heeled female shoe 2. The shoe sole 1 has a device for adapting the shoe sole 1 to the outer contour of a human foot. or stretching device 3. This tensioning and / or stretching device 3 is integrated in an elastic subregion of the sole 1 and is effective for widening or narrowing the shoe sole 1 transversely to its longitudinal extent. In FIG. 19 it can be seen that the tensioning and / or stretching device 3 is arranged and effective in the partial region of the shoe sole 1 which carries the toe base joints of the foot. The shoe sole 1 is made of elastic material at least in this partial area. The tensioning and / or stretching device 3 is adjustable against the restoring force of the elastic sole material. In this case, a wide shoe sole 1 can be pulled together with the help of the tensioning and / or stretching device 3 to a perceived as pleasant, reduced sole width. Instead, it is also possible to widen a narrow shoe sole 1 with the help of the tensioning and / or stretching device 3 to the individually required sole width.

From Fig. 19 it is clear that the tensioning and / or stretching device 3 has two clamping and / or stretching elements 4, which are 5 m apart from each other with the aid of at least one adjustable spacer. This spacer 5 has threaded rods 6a, 6b, which carry at each of its two opposite rod ends an external thread, which external threads are screwed into complementary internal threads on the adjacent clamping and / or expansion elements 4.

The m the shoe sole 1 incorporated device is m shown in FIGS. 16 to 18 in more detail. As is apparent from Figs. 16 to 18, the two expansion elements 4 are connected by a spacer 5. By the spacer 5, the distance between the expansion elements 4 is adjustable. The expansion elements 4 each have an outer surface 31 and an inner surface 32, which are embedded in correspondingly shaped, receiving forms of the shoe sole 1 of a men's or women's shoe, for example, according to Figure 1 or 2. Thus, by adjusting the spacer 5 a metered elastic deformation of the shoe sole 1 can be achieved. The spacer 5 comprises two threaded rods 6a and 6b, each having an external thread 33 at their outer ends. These external threads 33 are received by threaded sleeves 8 with complementary shaped internal threads, so that a rotational movement of the threaded rods 6a and / or 6b in a linear movement of the expansion elements 4, ie a distance change of the expansion elements 4 away from each other or towards each other, implemented.

The threaded rods 6a and 6b are connected to a respective output shaft of a transmission 34 or go into this. Thus, the gear 34 drives the adjustment of the expansion elements 4.

The transmission 34 has a housing 35 with bearings 36 in which the output shafts are mounted. The bearings 36 are designed as inexpensive sliding bearings.

In the interior of the transmission 34 is on each output shaft, so each threaded rod 6a and 6b, a toothing part, a crown gear 37, respectively. The two oppositely disposed crown gears 37 mesh with a toothing part 38, which is arranged in a housing part of the housing 35, a drum 39, and which is manually driven by an actuating element 14 with a thumbwheel 40. By the thumbwheel thus both threaded rods 6a and 6b are equally driven via the gear 34.

FIG. 17 shows a sectional view through the transmission 34 from FIG. 16.

On each threaded rod 6a and 6b, a crown wheel 37 is arranged at one end and secured with an anti-twist device 41. secures and firmly connected. The threaded rods 6a and 6b are each mounted in bearings 36 in the housing 35.

The housing 35 forms a drum 39, in the interior of which a toothing part 38 is arranged. The toothing part 38 is connected to one end of a pin 42 in a connection region 43 in a material-locking and / or non-positive and / or form-fitting manner. At the other end of the pin 42, the thumbwheel 40 is formed. Thus, at least pin 42 and thumbwheel 40 form an adjusting element 14, with which the rotational position of the threaded rods 6a and 6b is manually adjustable.

The toothing of the toothing part 38 and the crown gears 37 is designed as a toothing.

Due to the configuration of the transmission 34 with a driving toothing part 38 which drives two second gear parts, the crown gears 37, which are arranged rotatably on the threaded shafts 6a and 6b acting as output shafts, an enlargement or shortening of the distance between the expansion elements 4 by rotate of the adjusting element 14 is reached when the external threads 33 are executed in the two threaded rods to each other in the same direction. This is exactly the opposite in an embodiment with a continuous threaded rod, for example, as shown in Figure 3, in which the external threads are designed in opposite directions to effect an adjustment of the distance between the expansion elements 4 and thus a deformation of the shoe sole.

The adjusting element 14 is mounted on a bearing 44. The adjusting element 14 is further mounted in a sliding bearing 45 and axially displaceable between a solid and an inserted position. FIG. 17 shows the adjusting element 14 in the inserted position. At the toothing 38 at least two axial regions are formed. Em first axial region is formed as a region with spur gear 46, and a second axial region is designed as a cone 47 with teeth. The cone 47 has a toothing and a to the end of the pin 42 hm increasing outer diameter.

In the retracted position of the actuating element 14 shown, the first axial region, ie the region with spur gear toothing 46, meshes with the toothings 48 of the crown gears 37. The toothing adjustment 38 is rotatably arranged in the drum 39, and the threaded rods 6a and 6b are engaged by the setting wheel 40 drivable. The transmission 34 is thus released.

Figure 18 shows a sectional view of the transmission 34, in which the adjusting element 14 is arranged in the extended position. Extracted and inserted position of the actuating element 14 are each predetermined by a stop 49 on the toothing 38 and a stop 50 on the adjusting wheel 40 and the pin 42.

In the extended position, the toothing adjustment 38 is displaced along the inside 51 of the drum 39 ms inside the transmission 34. As a result, the toothing on the cone 47 of the toothing part 38 engages with the toothing 48 of the crown wheels 37. Since the outer diameter of the cone 47 increases outwardly and is greater than the outer diameter, ie the tip circle diameter of the spur gear toothing 46, the crown wheels 37 are pressed against bearing surfaces 52. This creates a frictional force between crown gear 37 and bearing surface 52 with housing 35, which prevents a rotational movement of the threaded rods 6a and 6b. Thus, the transmission 34 is locked in the extended position of the actuating element 14 and can not transmit rotational movement. Em automatic adjustment the distance of the expansion elements 4 is thus effectively prevented.

To reinforce the clamping effect, in a further embodiment, the bearing surfaces 52 and the sides of the crown gears 37 facing them are provided with a matching pattern of elevations and depressions.

To further secure the locking and the release, two circumferential grooves are inserted and arranged in the pin 42 at a distance such that both in the pushed-in position as well as in the extended position, one groove in each case extends axially

Position of the bearing 44 passes. Thus lock the balls of the bearing 44 with the respective groove, and the actuator 14 is displaced only with a certain minimum force.

In a further embodiment, instead of or in addition to the setting wheel 40, a receptacle for an adjusting tool, for example a hexagon socket wrench or a Phillips screwdriver, is formed.

In a further exemplary embodiment, latching lugs 39 are formed on the inside 51 of the drum, into which the toothing part 38, in particular with a toothing, engages in an extended position but not in an inserted position. Thus, a lock is also achieved.

In a further embodiment, the axial sequence of the regions of the toothing part 38 is just the reverse, so that in the inserted, but not extended position locking is achieved.

In Fig. 20, the shoe sole of the one shown in FIG

Women's shoe 2 shown in a partial cross-section in the region of the tensioning and / or stretching device. Also the ladies shoes according to Fig. 2, 4, 5, 6, and 9 to 15 have in further embodiments correspondingly formed shoe soles.

From Fig. 20 it is clear that the shoe sole has an upper sole region 50 made of hard-elastic sole material, wherein m this upper sole region 50 on the underside one or more impressions 51 are provided, which are filled with a soft-elastic sole material 52. In this case, the tensioning and / or stretching elements 31 are molded on both sides in such a way that these tensioning and / or stretching elements 31 pressurize the peripheral edge 53 of the upper, hard-elastic sole material 50 surrounding the soft-elastic sole material 52 or the adjacent soft-elastic sole material 52 can compress. It can thus be seen from FIG. 12 that the tensioning and / or stretching device 3 can deform the shoe sole of the shoe 2 m horizontally and thus m the plane defined by the shoe sole.

The invention further relates to a device for adapting a shoe sole 1 to the outer contour of a human foot, wherein the inserted and formed in the shoe sole 1 clamping and / or stretching device 3 has at least two clamping and / or stretching elements 4, with the help of at least an adjustable spacer 5 are mutually variable in their distance.

For an embodiment of the invention, it is characteristic that the spacer 5 has a gear 34, which comprises at least one stage with reduction gear, that the gear 34 with a drive shaft 42 and at least one, arranged at an angle to the drive shaft 42

Output shaft is inserted or molded in the shoe sole, that the drive shaft 42 with a tool-free manually operable actuator 14 and the at least one output shaft are connected to a threaded rod and that the threaded rod carries at least one of its rod ends an external thread which is screwed into the complementary internal thread of an adjacent clamping and / or expansion element.

The device according to the invention, which can be integrated inconspicuously into finished footwear and can be comfortably operated, makes it possible to adapt the shoe to the orthopedic necessities and the needs of the wearer, especially in the most stressed part of the toe bale.
