Abstract

Described is a sports shoe with a sole which includes a flexurally stiff girder section (1) extending essentially over the whole of the sole. The cross-section of the girder section exhibits at least one horizontal zone and at least two zones (1w, 1s) located on each side of the horizontal zone and extending essentially at right angles downwards and/or upwards, both shell-upper components (6, 9) and sole-plate parts (5, 8, 15, 16) being attached to the girder section (1).

Description

Sports shoe

The invention relates to a sports shoe with a sole structure and shell parts arranged thereon in an adjustable length and / or width.

Sports shoes, especially ski shoes, but also roller skates and ice skates, as well as other sports shoes, are nowadays mostly made of plastic by means of tips. In order to achieve the strength required for many sports shoes, large quantities of * plastic are often required, whereby not only the often high starting price of the raw plastic, but also the costs of manufacturing it are disadvantageous. A particular problem in manufacturing is to be found in the fact that a large number of shapes are required for each model in order to cover all shoe sizes. In addition, there is the fact that the shapes, particularly in the case of ski boots, are complicated and correspondingly expensive.

For this reason, shoes with different adjustment mechanisms have become known. For example, EP-A2-356 398 describes an adjustment shoe construction by the applicant, an embodiment with a two-part sole being shown, which has a front part and a heel part, which are connected to one another in a length-adjustable manner by means of two round rods arranged in parallel. Each of these shell parts has a transverse groove on the top, on which lateral shell parts are guided so as to be adjustable in width. Furthermore, these shell parts are connected to one another by means of side cover plates. In a further embodiment, the front part and the heel part of the sole are each made up of two blocks arranged next to one another, which are used for Width adjustment are connected to each other by means of screws. In this embodiment, the length is adjusted by means of the side cover plates. In order to achieve the required strength, however, the sole structure of this sports shoe must be. be made from high quality and therefore expensive materials.

Furthermore, a shoe construction is described in FR-2 629 313, which can be adapted to the individual foot arch of the user. With this construction, however, no sports shoe with a length and / or width adjustment can be realized.

Furthermore, a low shoe is described in DE-OS 2 535 982, which consists of a front and a heel part, which are connected to each other in an adjustable length via a frame profile integrated in the heel. On this basis, too, no corresponding sports shoe can be realized.

An object of the invention is to provide a sports shoe that can be manufactured more easily and cheaply and yet meets all the requirements that are placed on sports shoes, in particular ski boots, and that also has sufficient strength.

This object is achieved in a sports shoe with a sole structure and with shell parts which are arranged to be adjustable in length and / or width, in that the sole structure has a rigid support profile which extends in the longitudinal direction essentially over the entire sole structure, the cross section of which has at least one horizontal section and at least two , arranged on both sides of the horizontal section, extending substantially vertically downwards and / or upwards, both shell parts and sole plate sections being attachable to the support profile. The invention results in a stiffening of the sports shoe, which makes it possible to save expensive material in many places and at the same time expands the field of application of the sports shoe, since the support profile can serve as a central fastening point for other stiffeners and / or additional devices.

It is particularly advantageous if shell parts, sole plate sections or sole plate sections with shell parts are attached to the support profile and are adjustable in the longitudinal and / or transverse direction, since this opens up the possibility of simplified production of the shoe and a complete size series of a shoe model by just a few Items can be covered. At the same time there is the possibility of a size adjustment in the course of the final production and / or for the user.

In this sense, it can also be expedient if the carrier profile consists of at least two profile parts which interlock, at least in sections, in a form-fitting manner, can be displaced in the longitudinal direction and can be fixed in different relative positions.

An expedient development of the subject matter of the invention is characterized in that two rigid lateral, rear leg supports are attached to the carrier profile. The considerable forces acting on the leg supports are hereby introduced directly into the support profile.

Further features of the invention are characterized in the remaining subclaims.

The invention and its further advantages are explained in more detail below with reference to exemplary embodiments which are illustrated in the drawing. 1 shows a ski boot according to the invention in a side view and in an exploded view, FIG. 2 1 shows a top view of a carrier profile that can be used in a shoe according to FIG. 1, and FIG. 2a shows a rear or front view of the carrier profile according to FIG. 2, FIG. 3 shows a cap part that can be used in the shoe according to FIG. 1, and FIGS. 4a to 4g different individual parts in the front sole area of a sports shoe according to the invention in different views, FIGS. 4d and 4g showing sections along the lines IVd-IVd and IVg-IVg in FIG. 4a, FIG. 5 a further embodiment of the invention in a partially sectioned view 6 and FIG. 7 the rear and front part of the sole structure of the shoe according to FIG. 5 each in a bottom view, FIG. 8 a section along the line VIII-VIII of FIG. 5, FIG. 9 in a front view and Fig. '10 in a plan view of a sole tip, as shown in Fig. 5 and 7, Fig. 11 and 12 two further versions of the support profile and the sole structure in cross sections, Fig. 13 shows another embodiment of the invention in part ller side view, partially sectioned, Fig. 14 and 15, the front and rear part of the sole structure of this shoe in bottom view and plan view, Fig. 16 shows a section along the line XVI-XVI of Fig. 13, Fig. 17 another embodiment of a Carrier profile in side view, Fig. 18 shows the rear part of this profile in top view, Fig. 19 shows the front part of this profile in side view, Fig. 20 shows a section along the line XX-XX in Fig. 17, Fig. 21 shows a ski boot according to the invention with lateral Leg supports and cuff, Fig. 22 is a bottom view of the sole structure or the support profile of this ski shoe, Fig. 23 is a section along the line XXIII-XXIII of Fig. 22, Fig. 24 shows another embodiment of a ski shoe according to the invention with side leg supports and cuff in side view 25 shows this shoe in a bottom view, FIG. 26 shows a cross-divided and adjustable bracket of an upper legrest part in a front or rear view, FIG. 27 shows it in a cross section itt the arrangement of a footbed and an outsole on a support profile, Fig. 28 in one Cross-section the arrangement of a beveled outsole on a support profile, Fig. 29 in a side view the rear part of a support profile with attached, adjustable side leg supports, Fig. 30 is a section along the line XXX-XXX of Fig. 29, Fig. 31 in a view like FIG. 29 another embodiment, FIG. 32 a section along the line XXXII-XXXII of FIG. 31, FIG. 33 in a longitudinal section in partial view a shell tip and a sole tip for attachment to a support profile, FIG. 34 in one partial top view of a carrier profile with side-adjustable sole end parts arranged thereon, FIG. 35 shows a top view of the front part of a sole structure with a sole end part tiltably mounted on a carrier profile, FIG. 36 shows a side view of FIG. 35, FIGS. 37 and 38 show sections along lines XXXVII XXXVII or XXXVIII-XXXVIII of Fig. 35, Fig. 39 in a cross section a variant of a tiltable fastening of a sole part 40a is a bottom view of an adjustable shell cap for a roller skate, FIG. 40b is a cross section of this shell cap, fastened to a carrier profile, FIG. 40c is a wheel fork for fastening to the carrier profile shown in FIG. 40b, FIG. 40d an ice skate insert, attached to the carrier profile, Fig. 42 and 41 an embodiment of a roller skate according to the invention in side or. 43 and a further embodiment of a roller skate according to the invention in a side view.

According to FIGS. 1 to 3, a shoe designed here as a ski shoe according to the invention has, as a supporting part of its sole structure, a carrier profile 1 which extends over a large part of the length of the shoe and which, as can be seen from the cross section shown in FIG. 2a , has three horizontal sections lw and four vertical sections ls. A grid of longitudinal slots 2 is formed in the horizontal sections. The carrier profile 1 is preferably made of metal and, for example, by Bending, extruding or forging and, above all, longitudinally rigid.

A rear section Z and a front section 4 of the shoe can be fastened to the longitudinal profile 1. The rear section consists of a rear sole plate part 5 and a rear shell section 6. The latter is provided on both sides with flexion slits 7, which enables an area 6b to be bent more easily inwards and outwards. This area 6b also has left and right sole plate sections 5b.

Similarly, the front section 4 has a front sole plate part 8, a front shell section 9, lateral flexion slots 10 and bendable areas 9b with associated sole plate sections 8b. 3, the sole plate sections 8b (also 5b) have transverse slots 11 and bores are formed in the front sole plate part 8 (also in part 5).

The shoe also has a tongue 13 and a rear part 14, these parts being connected in a suitable manner to the remaining parts of the shoe. Finally, two sole end parts, namely a heel end part 15 and a sole tip 16 can be fastened to the carrier profile 1 from below.

As can be easily recognized by the person skilled in the art, the parts described can be connected to one another and to the carrier profile 1 by means of screw connections (not shown here).

The size of the shoe shown can be changed, since the rear section 3 and the front section 4 are displaced in the longitudinal direction with respect to the carrier profile 1 due to the longitudinal slots 2 and can be fixed in the desired position. Furthermore, according to the flexion slits 7 and 10, the released areas 6b and 9b are pivoted inward or outward against the elasticity of the material of the shell sections and fixed, which results in a width adjustment of the shoe in the orthopedically relevant areas. The described length and width adjustment is usually carried out during the assembly of the shoe in order to set a predetermined shoe size, but a later adjustment is also possible in specialist shops or at most by the user.

In the shoe shown in FIGS. 4a to 4g in a front partial area, the carrier profile 1 consists of a sheet meandering in cross section with a total of six vertical sections ls and five horizontal sections lw. The front section 4 shown in FIG. 4a corresponds to that shown in FIGS. 1 and 3. From Fig. 4b and c, a front under sole 17 can be seen, which carries on its upper side a plurality of longitudinal webs 18 which are arranged so that they form-fitting with longitudinal webs 19 projecting downward from the carrier profile 1, which are defined by corresponding vertical sections ls , cooperate. This can be seen from FIGS. 4e and f. There you can also see one of several screws 20 which are inserted from below through bores 21 of the under sole 17, longitudinal slots 2 or bores of the support profile 1 and the transverse slots 8b of the front section 4 and cooperate with nuts 22 (FIG. 4d), so that a Screwing or adjusting the individual parts in the desired position is possible.

The sole plate part 8 encompasses the carrier profile 1 from the outside with lateral longitudinal webs 23 (FIG. 4g) projecting downwards, which also results in a positive fit here.

In the ski boot shown in FIGS. 5 to 10, the carrier profile 1 consists of two interlocking gripping profile parts 24, 25 which can be displaced in the longitudinal direction and can be fixed in different relative positions.

Both the rear profile part 24 and the front profile part 25 have an essentially rectangular tube cross section (see FIG. 8), the front profile part 25 representing an inner tube which is slidably displaceable in an outer tube formed by the rear profile part 24. The respective relative position of the profile parts 24, 25 can e.g. are fixed with the aid of a pin 27 penetrating both profile parts in corresponding bores 26. It should be noted that the front profile part 25 here, strictly speaking, has two closed cross sections, since it has an inner central longitudinal web 28 (FIG. 8). The front profile part 25 could just as well have a full cross-section, i.e. not be tubular but rod-shaped.

A rear section 3 of the shoe sits on the rear profile part 24, and a front section 4 of the shoe sits on the front profile part 25. It is therefore clear that a mutual displacement of the two profile parts 24, 25 leads to a change in the length of the shoe.

A width adjustment of the shoe is also provided in the embodiment according to FIGS. 5 to 10. The shoe has two lateral, width-adjustable, rear shell parts 29, which merge downwards into a double web 30, which overlaps the rear profile part 25

(Fig. 8) A threaded spindle 31 passes through the sole structure and is mounted in suitable bores in the double webs 30 and the rear profile part 25. Nuts 32 held in the double webs 30 cooperate with opposing threaded sections of the spindle 31, which can be turned from the outside by means of a tool, for example a screwdriver, whereby the shell parts 29 can be adjusted in the lateral direction relative to one another. In grooves retaining rings 33 held by spindle 31 between rear profile part 24 and double webs 30 prevent displacement of spindle 31 in the axial direction.

In order to enable the profile parts 24, 25 to be displaced relative to one another despite the spindle 31 passing through the two profile parts 24, 25, longitudinal slots 34 are formed in the front inner profile part 25 (FIG. 5, dashed lines).

The additional guidance of the rear shell parts 29 is achieved by two transverse bolts 35 which, like the spindle 31, in principle push through the sole structure, but without being connected to nuts like the spindle 31. The cross bolts 35 can be secured against axial displacement in any suitable manner. Longitudinal slots 34 ′ must also be provided for the transverse bolts 35 in the inner front (or the outer rear) profile part 25.

In an analogous manner, two lateral front shell parts 36 are mounted on the front profile part 25 in a laterally adjustable manner by means of a further threaded spindle 37 and nuts 38. In order not to impede mutual adjustment of the two profile parts 24, 25, longitudinal slots 39 are formed in the rear, outer profile part 24.

A heel part 40 and a toe part 41 as well as a sole plate 42 serving as slip protection and a front sole plate 43 are also fastened to the carrier profile 1. These parts are attached with the help of merely indicated screw connections. In particular, the heel part 40 and the toe part 41 should also have a positive connection with the carrier profile 1 or its two parts 25, 26 and / or other parts of the sole structure. For example, the front sole plate 43 has webs 44 and elevations 45 (FIGS. 9, 10), which in corresponding depressions 44 ', 45' on the underside of Engage sole portions of the tip portion 41 (Fig. 7).

11 shows an embodiment of the carrier profile 1 which is similar to that described above with regard to the tubular cross-sections, but in which the rear, outer profile part 24 has lateral widenings 46 on its upper side and webs 47 projecting upward like a comb. The asymmetrical widenings 46 are preferably only present in the heel area. It is shown here that additional parts, such as, in particular, lateral leg supports 48, only indicated and described in more detail below, can be held on the carrier profile by means of two screw bolts 49 penetrating the webs 47 and a common nut 50 held between two central webs. The leg supports 48 are additionally supported with their lower ends in recesses 51 in the widenings 46.

The outer rear profile part 24 has short, outwardly extending projections 52 on its underside, so that a positive connection with a correspondingly shaped, slide-on midsole section 53, e.g. consists of polyurethane, is possible.

Parts of the carrier profile 1 which are telescopically displaceable in the longitudinal direction relative to one another do not have to be tubular. As shown in FIG. 12, the carrier profile 1 can consist of a first, lower profile part 54 with webs 55 protruding upwards like a comb and from a second, upper profile part 56 with webs 57 that are comb-like downwards, said webs 55, 57 interlocking in a form-fitting manner. As shown in FIG. 11, the upper profile part 56 here has additional upper webs 47 and lateral widenings 46, and a lower sole section 53 is also pushed onto the lower profile part 54.

In the embodiment according to FIGS. 13 to 16, the carrier profile 1 consists of two telescopically in the longitudinal direction mutually displaceable profile parts, a lower, rear profile part 58 and a front, upper profile part 59. As in the embodiment according to FIG. 12, here, too, webs 55 protrude from a base plate 60 of the lower, rear profile part 58, namely a middle and two lateral webs, and from the upper, front profile part 59, four webs 57 project downward like a comb. The webs of the two profile parts 58, 59 are in a positive connection, so that the two profile parts can only be moved in the longitudinal direction. The two profile parts 58, 59 are advantageously fixed against one another with transverse bolts, as shown in connection with FIGS. 5 to 8. Likewise, rear or front shell parts can be mounted on the support profile 1 in a transverse manner, which is illustrated in FIG. 16. FIG. 16 differs only in the configuration of the support profile and in FIG. 8 in that the adjustment of front shell parts 36 is shown, so that detailed explanations for this are unnecessary. The base plate 60 of the lower profile part 58 forms a sole part onto which, for example, a plastic sole could be glued.

A further embodiment of the invention according to FIGS. 17 to 20 shows a carrier profile 1 which consists of a profile rear part 61 and two rods 62 which are positively connected to this profile part 61 in such a way that a telescopic lengthening or shortening of the entire support profile 1 is possible. The rods 62 are guided between webs 63 projecting downward from the profile part 61, which is described further below, e.g. also emerges from FIGS. 22 and 23.

Falling out of the rods 62 is prevented by transverse bolts 64 which are seated in bores 65 of the profile part 61 and bores 66 of the rods 62, and are guided in longitudinal slots 67 of the rods 62 and in longitudinal slots 68 of the profile part 61. It should be noted that a threaded spindle 37 according to FIGS. 5 and 7 can take the place of the front bolt 64 in order to enable a width adjustment of shell parts.

The rods 62 can be fixed by means of a cross bolt 69 which passes through one of several bores 70 in the profile part 61 and a bore 71 in the rods 62. A bore 72 in the rods 62 is used to fix a tip portion of the shoe, which is shown below.

Just as in the embodiment according to FIG. 11, the profile part 61 has one-piece lateral extensions 46, which is also clear from FIG. 20. On these widenings there are holding angles 73 with their horizontal legs, the latter engaging in slots of longitudinal webs 47 of the profile part 61 which project upwards. With the aid of pin-slot screw connections 74, it is possible to fix the cross-adjustable angles 73 in this way.

On the two vertical legs of the angle 73, lateral leg supports 48, which are described in more detail below, are adjustably mounted in the height direction with the aid of adjusting or canting fittings 75. Such fittings 75 are commercially available and allow a secure adjustment in the vertical direction according to a slight path, which is predetermined here by vertical slots 76 in the vertical legs of the angle 73.

In the ski boot according to the invention shown in FIGS. 21 to 23, the carrier profile 1 is largely similar to that shown in FIGS. 17 to 20, ie it has a rear profile part 61 with rods 62 that can be telescopically displaced therein. The boot also has a tip part 41 and lateral front shell parts 36, which are adjustable in width by means of a spindle 37 in an analogous manner to that shown in FIGS. 5 to 8. A front one Sole plate 43 is positively connected to the rods 62 or the tip part 41, the cross bolt 69 already described in connection with FIG. 17 and a further cross bolt 77 serving to fix the individual parts of the sole structure, which through the bores 72 (see FIG 19) of the rods 62 and through corresponding bores in the soleplate 43 or a lateral lower edge of the tip part 41.

In the heel area of the shoe, a heel footbed 78 is provided, which rests positively on the profile part 61 provided with upstanding webs 47 and is secured by transverse retaining pins 79. From below, a sole insert 80 is preferably in a positive connection with the profile part 61, which also has webs 63 projecting downwards.

Two side leg supports 48 are attached to the carrier profile 1. In each of these leg supports 48, two horizontal slots 81 are formed in their lower end region, through which guide webs 82 projecting laterally from the profile part 61. Furthermore, an adjustment screw 83 is provided for each leg support 48, which passes through the support 48, is held on it against axial displacement by means of a locking ring 84 and interacts with a nut 85 held between webs 47. By turning the adjusting screws 83, the leg supports 48 can thus be placed more or less outwards or inwards.

In the present example, the side leg supports 48 are pulled up over the ankle area. At the upper ends of the leg supports 48, a bracket 87 is mounted by means of adjustable and lockable pin cross recess connections 86, which in the present example encompasses the leg from the front and forms the upper end region of the leg supports. On the other hand, in the bracket 87 there is a closable sleeve 88, for example by means of a pin Slot connection 89 conveniently movably mounted. The pivoting movement of the cuff 88 to the rear can be limited by a stop 90 provided on it, which interacts with the leg support 48. Brackets and cuffs of the type used here are partly described in more detail in WO 92/16120 by the applicant.

A displaceable tongue section 91 covers the space between the front cap of the tip part 41 and the cuff on the upper side. Of course, the shoe can also be completed by other shell parts and a conventional liner.

The connection of the lateral leg supports 48, which consist of a rigid material, to the carrier profile 1 or the rear part 61 thereof is particularly advantageous, since this results in an excellent introduction of forces into the sole structure of the shoe and thus into the skis.

The shoe according to the invention according to FIGS. 24 and 25 has a structure of the sole area and the front shell area which has already been described in detail in connection with the preceding figures. However, the design of the rear shell area with leg supports is different, which is described in more detail below.

Leg supports 92, which can also be regarded as anatomically shaped shell sections, are supported with their lower ends on the rear part 61 of the carrier profile 1 in the same way as the leg supports 48 of the embodiment according to FIGS. 21 to 23. The leg supports 92, however, have a lower part 93 which only extends up to or slightly beyond the ankle area. Arm-like upper parts 94 are fastened in an adjustable and fixable manner to these lateral lower parts 93, which at their upper ends merge in one piece into a front circumferential bracket 95, on which - as in FIG. 21 - one closable sleeve 88 is mounted by means of a pin-slot connection 89.

The lower part 93 and the upper part 94 of each deinstop 92 are connected via three pin-slot connections 96, 97, 98. A central lower pin-slot connection 96 has a slit 96a running obliquely upwards in the direction of the upper part the lower part. Slits 97a, 98a parallel to this slot 96a are also provided in the lower part 93 for the connections 97, 98. The latter, however, have additional circular or tangential slots 97b, 98b in the upper part, which enable the upper part 94 to pivot about the pin of the connection 96. Furthermore, the upper part 94 can be moved up or down.

In this way, the arm-like upper parts 94 together with the bracket 95 can be individually adjusted in the vertical direction on both sides (canting setting) and can also be pivoted more or less forwards or backwards, all of these movements being adjusting movements, i.e. in use, the upper and lower parts 94 and 93 are rigidly connected to one another.

Optionally, the pin-slot connection 89 can have a slot 89a parallel to the slots 96a, 97a, 98a (dashed lines), which allows the cuff 88 to be counter-adjusted when the parts 94 including the bracket 95 are tilted to the left or right.

The lower parts 93 of the leg supports 92 are connected to one another via a rear extension 99 extending from them and a screw connection 100. The screw connection 100 can simultaneously be used for a width adjustment. The lower end of a flexible connecting piece 101 is also attached to the extensions 99 or the screw connection 100, and its upper end is connected to the rear end of the sleeve 88. This connector 101 is a Lose the rear cuff section with the cuff open.

Fig. 26 shows the upper ends of two leg supports 102 with a bracket 103 seated thereon. This bracket 103 is divided approximately in the longitudinal center plane of the shoe and the two bracket halves 103a, 103b can be displaced relative to one another in the vertical direction and by means of a screw connection 104 in the desired direction Position fixable. The screw connection 104 can be part of a pin-slot connection and the abutting surfaces of the bracket halves 103a, 103b can be roughened or have teeth 105.

FIG. 27 shows a carrier profile 1 with webs 47 projecting upwards (similar to FIG. 11 or 12) on which a footbed 106 or an insole rests, wherein longitudinal webs 107 projecting downward from the footbed 106 interact with the webs 47 of the carrier profile 1 . The footbed 106 could also be glued or screwed to the carrier profile 1 and can be made of foamed plastic, for example. The footbed can also be self-supporting or relatively stiff, so that it gives the entire sole structure additional strength.

28 shows a carrier profile 1 with longitudinal webs 108 projecting downward therefrom, an outsole section 109 with webs 110 projecting upwards being plugged onto the carrier profile 1 from below and being fixed by means of one or more transverse bolts 111. The outsole or its section 109 can be beveled in the transverse direction as shown, so that the entire shoe tilts by a small angle. This can be useful for adapting to special anatomical (orthopedic) conditions or to a driving style. On the other hand, such a beveled outsole can be quickly replaced with a conventional, straight outsole (or section). 29 and 30 show a very simple but secure and firm connection of lateral footrests to the carrier profile. Shown is the rear part 61 of a carrier profile 1, corresponding approximately to the embodiment according to FIG. 17, with side extensions 46, with a on the rear side The heel part 112 together with an outsole extension 112a is fixed to the part 61 of the carrier profile 1 by means of a cross pin 113.

Two side leg supports 114 are each screwed to webs 117 of the profile part 61 with the aid of two screw bolts 115 which penetrate vertical slots 116 in the supports. The screw bolts 115 can - as shown - be screwed into threaded bores 118 of the profile part 61. Outwardly protruding guide extensions 119 formed with the profile part 61 engage through slots 120 in the leg supports 114, a certain play being expedient. Washers placed between the leg supports 114 and the profile part 61 or its webs 117

121 or the like determine the width of the shoe in the area of the leg supports 114. The height adjustment in two places not only enables a canting adjustment, but also - assuming the above-mentioned play - a forward adjustment of the leg supports 114, which e.g. can be provided with a bracket and a cuff (see FIG. 24).

Another possibility of such universal adjustability of the leg supports is shown in FIGS. 31 and 32. The leg supports 114 are each held in two places by means of a screw bolt 122 which engages in a nut 123 mounted on the profile part 61. The bolt

122 carries at its outer end a disc 124 with a slot for a tool or a coin. A centered cylinder piece 125, which is mounted in the leg support, follows inwards, and the screw bolt 122 sits eccentrically on this cylinder piece. A locking screw 126 is used to block the rotational movement of the disc 124, a locking ring 127 prevents axial displacement of the bolt 122 with respect to the leg support.

It can be seen that the leg support 114 can be raised or lowered according to the eccentricity by rotating the disc 124 by 180 °. Twisting through 360 ° or a multiple of 360 ° always leads to the same height, but to a change in the width of the shoe, since the screw bolt 122 is screwed into or out of the nut 123 and takes the leg support 114 with it during its axial movement .

34 and 35 show a possibility for the lateral adjustment of sole end parts, namely sole tip and heel end part. 33 and 34 on the left show such a fastening of a sole tip 128 to the rods 62 of a carrier profile 1, which here is designed as in FIGS. 17 to 19, but also differently, e.g. can be integrally formed. A transverse threaded spindle 129 or screw can be rotated on both sides in the sole tip 128, but is mounted axially immovably and is guided with its thread into threaded bores 130 of the rods 62. By turning the threaded spindle 129, the sole tip 128, which has a corresponding clearance 131 in the transverse direction, can thus be shifted to the left or right. In Fig. 34 the sole tip 128 is shifted to its extreme left position. 33 shows bores 132, 133 in the sole tip 128 or in the sole plate section of a tip part 41, in which corresponding sections of the threaded spindle 129 are mounted.

In an analogous manner, a heel end part 134 can be mounted on the rear end of the carrier profile 1, namely on a correspondingly graduated profile rear part 61. In addition to a transverse threaded spindle 135 (corresponding to the spindle 129 for the sole tip 128) there is also one transverse guide pin 136 is provided, which is secured in a suitable manner against axial displacement. The heel end part 134 is also in its extreme left position according to FIG. 34. Through the described transverse adjustment of the sole end parts, further adaptation to orthopedic peculiarities and / or to the particular application (eg slalom, downhill) or the personal driving style can be achieved.

35 to 39 show that sole end parts with respect to the carrier profile 1 can also be mounted such that they can be tilted and locked about an essentially horizontal longitudinal axis. 35 to 38, for this purpose, in the toe area of the shoe, axle stubs 139 projecting eccentrically from a cylinder 138 in longitudinal holes 137 of rods 62 of the profile part ^' 1 are mounted, which in turn are each eccentrically held in cylinder pieces 140, which are held in bores 141 of the sole end part, here a sole tip 142, are rotatably mounted. The cylinder 138 is supported on an inner surface of the sole tip which is arched up in the middle and which can consist, for example, of aluminum or polyurethane.

The adjustment arrangement just described, as best seen in FIG. 35, is provided in duplicate in a row in the front area of the sole tip. In the back is a similar one

Adjustment arrangement, but provided without a central cylinder. On both sides of the sole tip 142, cylindrical pieces 143 are rotatably mounted in corresponding bores and can be fixed by means of fixing screws 144. It should be noted here that the cylinder pieces 140 of the two front adjustment arrangements can also be blocked in one way or another. Eccentrically short pins 145 protrude inward from the cylinder pieces 143

Longitudinal slots of the carrier profile 1, in this case the

Profile rear part 61 are guided. From the above it can be seen that by turning the cylinder pieces 140 or 143 a lateral tilting of the sole tip 142 - in general a sole end part or also an entire sole with respect to the profile part 1 and thus the entire remaining sole structure is possible, whereby an adaptation to orthopedic or driving conditions is feasible.

In the embodiment according to Fig. 39, 146, e.g. a heel end part attached two inner lateral inserts 147 with inwardly facing, concavely curved and toothed strips or a corrugated guide surface 148. An upwardly arched support insert 149 rests on the inner bottom surface of the sole end part 146. On the other hand, on the left and right side surfaces of a carrier profile 1, outwardly facing, convexly curved guide surfaces 150 are provided on inserts 151 connected to the carrier profile 1. The guide surfaces 150 or the like with toothed strips. provided and they cooperate with the guide surfaces 148 on the sole end piece, a screw connection 152 being provided on each side, which, in the manner shown, enables the mutually associated guide surfaces 148-150 to be pressed together.

After loosening the screw connections 152, a lateral tilting of the sole end part 146 with respect to the carrier profile 1 into a desired inclined position is possible. The screw connections are then tightened again.

40 to 43 illustrate the application of the invention to ice skates or roller skates by way of example.

40a first shows a front cap 153 with bottom edges 154 and sole plate sections 155. Cross slots 156 are formed in the latter in order to enable a connection to a carrier profile 1 (FIG. 46). One possibility for cross adjustment is through an indicated spindle 157 or screw connection is provided, which runs across the carrier profile 1 and can be mounted therein or can be designed similarly to a transverse adjustment according to FIG. 8 or FIG. 11. Another possibility for width adjustment is provided by the use of a transverse screw connection 158, which engages two longitudinal webs 159 projecting downward from the sole plate sections 155. This configuration requires an opening 160 in the carrier profile 1 (see FIG. 40b).

The carrier profile 1 shown in cross section in FIG. 40b has the shape of an inverted U, the legs of which are angled inward again. This profile shape enables the insertion and subsequent screwing of additional parts, e.g. 40c, which have an upper plate 162 which can be positively inserted into the carrier profile 1 and can also be easily replaced. Such wheel forks 161 can also be seen in FIGS. 41 and 42.

Instead of the wheel forks 161, runners 163 (FIG. 40d) can also be inserted into the carrier professional 1 in the same or a similar manner, from which it can be seen that a shoe can be quickly converted from a roller skate into a skate or vice versa. In addition, there is a factory simplification of production.

41 and 42 show a roller skate with a carrier profile 1, to which three wheel forks 161 lying one behind the other with castors 164 are attached in the manner described above. In other profile configurations, as described in many variants above, the wheel forks 161 could, for example, also be screwed onto the carrier profile 1. Furthermore, a so-called stopper 165 is attached to the carrier profile 1 at the front. In the two shoes shown in FIGS. 41 to 43, a stiffening strip 166 is arranged at their rear end, which extends from the sole structure essentially to the upper edge of the shoe and is connected to the carrier profile 1 directly or via a rear shell part 167. The stiffening strip 166 can be made of plastic, for example, and can contain an inner steel strip 168, which is directly connected to the carrier profile 1 on its underside, for example, inserted into a slot and / or screwed there. This steel strip 168 is dashed in FIG. 41 and hatched in FIG. 42. Bridge pieces 169 lie between the stiffening strip 166 and the shell of the shoe. The rear shell of the shoe has a pronounced flexion point 170, which is created by a corresponding material recess.

The stiffening strip 167 is flexible with respect to pivoting of the upper or upper of the shoe, but is rigid in the lateral direction, which results in an optimal transfer of forces from the foot to the rollers or runners with a light construction of the shoe. The strip 167 also offers protection against injury.

A width adjustment of the shell is also possible with the shoes according to FIGS. 41 to 43. Spindles or screw connections provided for this purpose are only hinted at, since they have already been described in some versions above and are designated by reference number 171. Likewise, the carrier profile 1 can be adjustable in length in one of the ways described above.

43 shows a shoe which is similar to that of FIGS. 41 and 42, but in which a complete on-line roller skate chassis 172 with five rollers 173 lying one behind the other is fastened to the carrier profile 1. A stopper 174 is attached to the rear end of the chassis 172.
