Abstract

The invention relates to insoles for ventilation of shoes (A43B 17/08). Said novel insoles for ventilation of shoes provide for the aim of producing an insole for active ventilation in a simple, effective and economical form. The insole can be placed in any shoe. Ventilation occurs by means of air channels in the insole. The air channels comprise one piece and are externally surrounded in cross-section. The air channels run in the rolling zone of greatest pressure loading, from the ankle to the ball region, along the external side of the foot, fanning out there and extending at least to the region of the toes. The pressure loadings thus act and progress one after the other from the heel via the external side of the foot to the ball region. Each air channel also remains airtight for the rolling movement on lateral pitching during pronation of the foot. Each air channel is thus serially sealed in the rolling direction and can then lead fresh air from the heel region into the toe region. After ventilation, circulation and eddying around the foot environment, the dampness evaporates through air-permeable constructions or materials.

Description: VENTILATION INSOLE

The invention relates to insoles for ventilation for footwear (A 43 B footwear 17/08 insoles with ventilation).

The following insole corresponds to the current state of the art and comes closest to the understanding of the invention, DE 297 21 900 U1, with a description of the features and design defects from which the new invention differs:

DE 297 21 900 U1:

The cavities of the insole run over the entire sole, from the heel to the toe and converge there (claim 1). The insole consists of a lower part and an intermediate part with ribs, so that an upper part is used to create cavities. Thus, the cavity consists of two parts, the lower part and the upper part. So that the ribs do not press into the foot, a more stable or thicker material must be used for the upper part, as described. However, this upper part would limit the elasticity of the insole. The unfavorable construction does not allow the ducts to close tightly due to pressure loads alone, because the ribs prevent the upper and lower parts from being sealed (description and section AA). The angular cross-sectional shape of the cavities also prevents tight closing in the corners. According to section AA, Figure 2, the height of the insole is approx. 15 mm, with a width of approx. 60 mm and is much too high to enable easy insertion in a shoe. In addition, the cavities also run on the inside of the foot, where there is hardly any pressure load in the longitudinal arch when walking and the cavities here do not close tightly. Adequate and functioning ventilation is only possible with valves (claim 3). The air ducts have no openings that face the top of the insole. The air change takes place via hoses, which are located at the back of the heel and at the toe. Furthermore, it requires a high manufacturing cost because of it it is difficult to technically connect a hose to the cavities of the insole. An air change with hoses (claim 2) and valves (claim 3) that run in the shoe is certainly annoying and makes it difficult to use in a shoe. This means that a shoe would have to be made for this insole. The insole can therefore not be easily inserted into every shoe.

DE 200 00 630 U1 is also known:

The insole (variant I) only has air ducts that are open to the lower side of the sole (the air ducts are not enclosed on the other side in cross section). As a result, in order to guide the air, the insole must lie close to the inner shoe in order to form a tight channel. The surface of the liner, which is rough, must be taken into account. Seams, material transitions and bulges of the inner shoe make sealing to the shoe more difficult. The edges of the air duct serve as check valves and are intended to prevent the air from escaping sideways. The insole moves when walking or during sporting activities, so that any air that may have been sucked in escapes laterally and makes it difficult to direct the air. In addition, the sole of the shoe bends at every step in the ball area and does not allow a seal to the air ducts of the insole, so that tight air channels can hardly be created. The air ducts run straight and are also located on the inside of the foot, where there is hardly any pressure load in the longitudinal arch when walking. The air ducts of the insole have no openings in the rear heel area (top view, section AA) that face the top of the insole. The air is only sucked in through openings in the shoe or through complex constructions. This means that a shoe would have to be made for this insole and the insole cannot be inserted into every shoe without problems. The cross section of the insole (section BB) shows that the air ducts are far apart, about 3.3 times as wide as the cross section width of the air ducts. The consequence of this is that the remaining contact surface of the insole prevents the air ducts from closing, since the greatest pressure load runs to the larger contact surface. This applies analogously to variant II. Variant II shows a shoe sole and is not an insole. The task of the newly invented insole for ventilation for footwear is to create an insole for active ventilation in a simple, effective and inexpensive form. The newly invented insole has the same height, elasticity, shape and properties as conventional insoles, for example as in sports shoes. The insole can then be easily inserted into any footwear.

This is solved by air ducts (3) with the features of the description, drawings and claims.

When rolling and walking, the greatest impact energy is in the heel area on the outer edge of the foot, i.e. on the outside of the foot. After a pronation of the foot to the ball area and toe area, it is ceded. The air ducts (3) therefore run in the rolling zone with this greatest pressure load, at least from the heel, on the outside of the foot closely to the ball area, fan out there and then at least to the toe area (FIG. 2).

Thus, the pressure load acts and moves one after the other precisely on the air ducts, from the heel over the outside of the foot to the ball area and then to the toe area. Therefore, even when swaying sideways, when pronating the foot, every air channel remains sealed from the rolling motion. In this version, the air ducts do not require valves. The air duct is closed tightly one after the other in the rolling direction and can thus direct air from the heel area to the toe area.

The openings of the air channels (14) in the rear heel area allow the air to be sucked in around the heel (FIG. 3) or through the footwear (FIG. 4). The openings in the toe area blow in the air. The openings in the central area, if desired, cause suction when exiting and blowing in upon occurrence. With every performance there is ventilation, circulation and swirling of the air around the foot. This improves the evaporation of the moisture and thus the ventilation.

Around the openings (14) there are aerodynamic depressions / extensions (15). These enable good air exchange and prevent the insole from sucking up. The air channels preferably project above the upper edge of the insole itself, so that the height projection (12) enables a larger cross section of the air channel and good opening of the air channel after the pressure load. Depending on the version, this protrusion is also a bead (13; Fig. 15).

The material properties and thicknesses are selected so that the material thickness of the insole under pressure is greater than the sum of the material thickness above and below the air duct in the unloaded state. When walking, this causes the air ducts to close securely with a maximum cross-sectional size and therefore the best possible ventilation. An exemplary embodiment based on FIG. 5: the insole has a height of approx. 5 mm unloaded, the air duct has a diameter of approx. 6 mm unloaded, the opening of the air duct has a diameter of approx. 3 mm unloaded and the wall thickness is approx. 1, 5 mm unloaded. The height overhang is approx. 1 mm. When the insole is loaded by approx. 2 mm, the air duct is already tight, even though the opening is approx. 3 mm high.

A web (9) between the air ducts, approx. As high as the insole itself, enables the air duct to be opened quickly and easily after the pressure load. A raised edge (8) along the air ducts also enables good and quick opening of the air duct after the pressure load.

An air duct consists of only one part and thus enables absolute tightness even after prolonged use. The cross section of the air duct is enclosed overleaf. This means that the insole does not need to be tightly connected to the liner to ensure proper ventilation. At the same time, there is no need to pay attention to the fit of the insole and the interior of the shoe.

The air ducts have a round to oval cross section or D cross section. These favorable shapes result in a tight seal when walking and a good and quick opening after pressure.

A further embodiment is that at least one air duct widens, as shown in FIG. 12, and thus enables greater air circulation. After the expansion, the air duct tapers again or it divides. Depending on the version, there is a compression layer (5) consisting of elastic materials or a simple fabric insert above or below the air ducts or the insole, in order to obtain additional compression and sealing of the air ducts when under pressure, and it also serves to compensate Bumps. The compression layer (5) as well as an existing cover (6) can be provided with openings (14) or extensions (15), for example if the materials do not let enough air through.

The amount of ventilation is simply variable due to the number of air channels and cross-sectional shape. The air ducts also have damping properties that are also variable through the use of different cross-sectional shapes and material properties. The air ducts are made of compressible and elastic materials. Depending on the manufacture and design, the air ducts are located in a recessed area of the insole (17).

A base layer (7) connects the insole depending on the version. Notches, air ducts and holes on the insole improve air circulation. The air channels of the insole can be connected to or lead into ventilation paths, ventilation channels or ventilation openings, for example on the footwear (FIG. 4). Depending on the version, the air ducts can run over the outer edge of the insole (1). The insole can also be deformed according to basic anatomical rules, so that it can also be used for orthopedic / medical purposes, for example with a spreading foot. Valves or valve-acting constructions on the ventilation system support air circulation if necessary. The ventilation system includes all components of the ventilation, such as footwear, insoles, air channels of the insole, air-permeable constructions and materials on the ventilation system and channels leading to the outside. The insole itself can be equipped or combined with gas chambers, cell construction, liquid, gel pad and the usual materials. The new insole can also be firmly connected to the footwear so that it becomes a solid component.

The function of the ventilation system can be demonstrated by extending the air ducts for demonstration purposes and placing them in a container with liquid. Air bubbles form when unrolling. The air ducts (3) can be designed in different variations (2/10/11). The air channels (3) version (2) shown in Figure 5, 6, 8, 10, 11 and 12 has only one air duct. Version (10) shown in Figure 7, 9, 13 and 14 have at least two air ducts. Version (11) shown in Figures 15 and 16 has at least one air duct, but consists of one part with the insole.

Further designs and details that can be combined with one another are explained in FIGS. 1 to 16 and in the claims for protection.

Figure 1 shows an exploded view of the insole Figure 2 shows a top view of the insole Figure 3 shows a longitudinal section of the insole Figure 4 shows a longitudinal section of the insole as a variant Figure 5 to Figure 16 show cross sections of the insole of different variants

The exploded view of FIG. 1 shows the insole (1), the air ducts (3) with the design variants (2/10/11) and their openings (14) with their expansion (15) the compression layer (5), a cover (6) , and a base layer (7).

The top view of FIG. 2 shows the insole, the air channels (3) with the design variants (2/10/11), an upwardly drawn edge (1.1) of the insole, an orthopedic foot projection (16) and the openings (14). The openings are located in the heel area, offset in the longitudinal vault, at the beginning and end of the bale and are directed upwards. Around the openings (14) there are aerodynamic depressions / extensions (15). These enable good air exchange and prevent the insole from sucking up. The air channels run here on the outside of the foot and thus in the rolling zone with the greatest pressure load, within the orthopedic foot projection (16); this begins in the heel area over the outside of the foot to the ball area, fans out there and then at least to the toe area.

The longitudinal section of Figure 3 shows the insole (1), the air channels (3) with the design variants (2/10/11), a compression layer (5), an upwardly drawn edge (1.1), the openings (14), the Aerodynamic depressions / extensions (15), a cover (6). The openings of the air channels are for Open top. The ends of the air channels in the rear heel area and in the toe area form further openings or expand the already existing openings. The compression layer is used for additional compression of the air channels and to compensate for unevenness. A height protrusion of the air ducts compared to the actual insole enables a larger cross section of the air duct and a good opening of the air duct after the pressure load. The air duct (3) consists of only one part, is enclosed on the reverse and does not need the tight connection to the liner for ventilation.

The longitudinal section of FIG. 4 shows the insole (1), the air channels (3) with the design variants (2/10/11) in a shoe (18) with an air-permeable construction (19). At least one opening (14) in the air duct (3) leads to the outside.

The cross section of FIG. 5 shows the insole (1) with four individual air channels (3) of the embodiment variant (2) with a round cross section. A support layer (7), a cover (6) and a compression layer (5) connect the design here. This creates additional channels (4) and provided with openings leading upwards, these provide additional ventilation. The insole has a raised edge (1.1). A height projection (12) of the air ducts compared to the actual insole enables a larger cross section of the air duct and a good opening of the air duct after the pressure load. If necessary, an existing compression layer (5) enables an additional, even compression of the air channels under pressure and a compensation of unevenness. An air duct (3) consists of only one part and is enclosed on the reverse.

The cross section of FIG. 6 shows the insole (1), with two individual air channels (3) of the variant (2), with a D cross section. A raised edge (8), opposite the actual insole, along the air duct enables a good and quick opening of the air duct after the pressure load. A web (9), higher than the actual insole, between the air ducts also enables a good and quick opening of the air duct after the pressure load.

The cross section of Figure 7 shows the insole (1) with four air channels (3) Design variant (10) from one part, with an oval cross-section. The air channels in the bale area fans. A height projection (12) of the air duct compared to the actual insole enables the advantages already mentioned.

The cross section of FIG. 8 shows the insole (1), with three individual air channels (3) of the variant (2), with an oval cross section. The insole is flat here and has no raised edge. A height projection (12) of the air duct compared to the actual insole enables the advantages already mentioned.

The cross section of FIG. 9 shows the insole (1), with three air channels (3) of the embodiment variant (10) made of one part, with an oval cross section. The air channels fan out in the bale area. A height projection of the air duct (12) compared to the actual insole and a compression layer enables the advantages already mentioned.

The cross section of FIG. 10 shows the insole (1), with two individual air channels (3) of the embodiment variant (2), with a flat oval cross section. The air channels and a web (9) are at least as high as the insole itself. The web (9) enables the air channel to be opened quickly and easily after the pressure has been applied. An existing compression layer (5) enables an additional, even compression under pressure and a compensation of unevenness.

The cross section of FIG. 11 shows the insole (1), with three individual air channels (3) of the variant (2), with an oval cross section. A web (9), here at the same height as the actual insole, between the air ducts enables the air duct to be opened well after the pressure load. However, the air duct has a height projection (12) compared to the actual insole. This creates additional channels (4) and openings leading upwards, which provide additional ventilation.

The cross section of FIG. 12 shows the insole (1), with at least one individual air duct (3) of the embodiment variant (2), with an oval cross section. The air duct is much wider and higher here and is a maximum of an inch. The air duct divides and fans out in the bale area. A height projection of the air duct (12) compared to the actual insole enables a larger cross section of the Air duct and a good opening of the air duct after the pressure load. FIG. 12 also shows a further embodiment in which at least one air duct widens in the longitudinal vault as shown in FIG. 12 and thus enables greater air circulation. After the expansion, the air duct can taper again or it divides and fans out in the bale area.

The cross section of FIG. 13 shows the insole (1) with five air channels (3) of the variant (10) made from one part, with a round cross section. The air channels fan out in the bale area. A height projection (12) of the air ducts compared to the actual insole enables the advantages already mentioned.

The cross section of FIG. 14 shows the insole (1) with four air channels (3), each consisting of two air channels of the embodiment variant (10), each with two air channels (3) and with an oval cross section. A web (9), higher than the actual insole, between the air channels enables the air channels to be opened well after the pressure load. An existing compression layer (5) enables an additional, even compression under pressure and a compensation of unevenness.

The cross section of FIG. 15 shows the insole (1) with four air channels (3) of the embodiment variant (11), consisting of one part with the insole. The air duct (3) is enclosed overleaf and does not need to be tightly connected to the liner for ventilation. The air channels fan out in the bale area. A protrusion above the air ducts compared to the actual insole forms a bead (13). The bead enables a larger cross section of the air duct, a good seal under pressure load and a quick opening of the air duct after the pressure load. The air channels fan out in the bale area. If necessary, an existing compression layer (5) enables the advantages already mentioned.

The cross section in FIG. 16 shows the insole (1), with seven air channels (3) of the embodiment variant (11), consisting of one part with the insole. The air duct (3) is enclosed overleaf and does not need to be tightly connected to the liner for ventilation. The air channels fan out in the bale area. There is no bead, the insole is flat. If necessary, an existing compression layer (5) enables additional, even compression under pressure and a compensation of unevenness. Reference symbol list
