Description

The present invention relates to a shoe sole with a dimensionally stable support, protruding from a projection down over the remaining footprint. The invention further relates to a shoe with such a shoe sole and finally the invention relates to a device for attachment to a shoe.

Shoe soles, as they are known from the DE 43 04 331 A1 , of the US 1,529,421 A , of the DE 672 137 C or DE 1 907 894 U emerge. The DE 43 04 331 A1 discloses a training sole with a solid and rigid sole and a fixedly disposed on the underside of the sole hemispherical support body. On the other hand shows the US 1,529,421 A a support element which is arranged on the underside of a shoe, wherein on the underside of the support element either a ball or a friction surface can be applied. An at least two-part Kufensandalale is in the DE 672 137 C discloses and another exercise device in the form of a shoe sole goes out of the DE 1 907 894 U out.

A disadvantage of the DE 43 04 331 A1 is that the sole is just a training sole and thus a durable wearing these soles an extremely high stress on the ligaments, muscles and joints has to result. The US 1,529,421 A and DE 672 137 C have the disadvantage that these soles also have a high stress on the joints and the ligaments apparatus result, resulting in a high risk of injury to the ligament apparatus and the ankle. The shoe sole of the DE 1 907 894 U has the disadvantage of high instability and again the risk of injury of the ankle and the ligament apparatus.

The object of the invention is to avoid the disadvantages described above and to specify a shoe sole or improved shoe or improved shoe or improved device for attachment to a shoe that is improved over the prior art. Among other things, an improved comfort to be achieved, otimale a step sequence can be achieved, orthopedic shoe inserts are replaced, a natural strengthening of the entire movement-tape apparatus can be achieved and the natural gait and its impact on the physique and organism can be improved.

This object is solved by the features of independent claims 1, 5, 6, 19 and 21.

Advantageous embodiments of the invention are defined in the dependent claims.

An essential idea with regard to the shoe sole according to the invention is therefore that the projection on the side facing the wearer is made softer than on the contact side. Softer is understood here and below in terms of Shore hardness. When using such soles, it is therefore possible that a natural, ergonomic sequence of steps is supported, so that the step sequence of the heel on the outer bale, on the inner bale leads to the metatarsophalangeal joint and there is given the optimal repulsion for locomotion. Furthermore, damping is achieved by the combination of the dimensionally stable carrier with the wearer facing the softer side of the projection in order to avoid stressing the sole of the foot, as would be the case with a continuous hard projection by a dimensionally unstable carrier.

In other words, the invention relates to a shoe sole with a dimensionally stable carrier, wherein a contact surface is at least partially formed by the carrier and a projection projecting from the carrier, wherein the projection on the carrier-facing side is formed softer than on the footprint.

In other words, a shoe sole is specified with a dimensionally stable carrier and an outsole, wherein a projection is arranged on the carrier, wherein the projection on the side facing the wearer is softer, than on the side facing away from the carrier.

In yet other words, the invention relates to a shoe sole with a dimensionally stable support, on which a projection is arranged, wherein the projection has a softer area and a harder area.

According to a further aspect of the invention, the projection is formed from at least two layers, wherein the upper layer is formed softer than the lower layer. Thus, not only the damping function is improved, but also reduces the abrasion of the surface of the projection, which comes into contact with a substrate. The position information here and in the following each refer to a dressed shoe with such a shoe sole in normal use.

In this case, the projection may consist of only one material, wherein the projection is doped differently or the projection is made of different materials.

It has proven to be particularly advantageous if the upper softer layer has a Shore hardness between 10 and 30, preferably between 15 and 25, and / or the lower, harder layer a Shore hardness between 45 and 65, preferably between 50 and 60, has. This Shore hardness results in a high attenuation, and a low abrasion of the lower layer of the projection. Particularly preferred materials are for the upper layer EVA cushioning cellular rubber and for the lower layer an EVA cellular rubber.

In a further advantageous embodiment of the shoe sole according to the invention a - possibly two- or multi-part design - outsole is arranged on the support, which forms the remaining footprint. This prevents damage to the dimensionally stable carrier. A slight wear of the outsole is achieved in that the outsole is preferably formed of EVA compact rubber, wherein the Shore hardness is between 45 and 65, preferably between 50 and 60.

Alternatively it can be provided that the projection in the carrier or in an arranged on the support - possibly two- or multi-part design - outsole is partially sunk, so that a better connection between the projection and the carrier or outsole is achieved. It is important that, nevertheless, it remains ensured that the projection protrudes, whereby a natural strengthening of the musculoskeletal system is possible when walking with the shoe sole.

A further alternative embodiment provides that on an underside of the carrier at least one further - possibly two- or multi-part design - outsole is arranged, over which the projection protrudes downward. By such a structure, the aforementioned advantages can be achieved again. Again, a low abrasion of the outsole is achieved in that the outsole is preferably formed of EVA compact rubber, the Shore hardness is between 45 and 65, preferably between 50 and 60, is.

According to a further aspect of the invention, the carrier is formed by a stable sole, preferably made of leather, fiber-reinforced plastic or cellular rubber. It is ensured by this measure that the projection does not press through the wearer on the sole of the foot while walking and cause pain.

To be particularly advantageous, it has been found that the projection is rotationally symmetrical - preferably cylindrical, frustoconical or spherical layer - constructed. This has the advantage that the production of such projections is particularly simple.

A preferred embodiment of the shoe sole according to the invention provides that the lateral surface of the projection is round or angular or substantially elliptical or polygonal, wherein preferably the lateral surface of the projection is formed circular. This supports an optimal sequence of steps and further improves the natural gait pattern.

In order to support the step sequence and to achieve an improved standing with the shoe sole, it can be provided that the lower layer of the projection is flattened.

It can also be provided that the projection is formed with differentiated and / or flattened edges.

Preferably, a gap is laterally formed between the projection and the outsole. Since the upper layer of the projection has a damping function and the upper layer can be extended depending on the degree of hardness when loading the projection, the gap provides the necessary space for expansion.

According to a further embodiment, it is provided that the carrier, the projection and the outsole are formed of separate, interconnected parts. As a result, parts that loosen in the course of use of the shoe sole, be renewed, so that spare parts can be provided.

By contrast, the carrier, the projection and the outsole may also be integrally formed, whereby a particularly simple production is achieved.

According to another aspect of the invention, the height of the protrusion is between 1.5 and 5 times the thickness of the outsole. Preferably, the height of the protrusion projecting above the outsole is between 0.25 and 4 times the thickness of the outsole. Particularly preferably, the upper layer of the projection has a maximum diameter which is 1.2 to 1.5 times as large as the maximum diameter of the lower layer. As a result, a particularly good damping and strengthening of the musculoskeletal system is achieved.

It has proven to be particularly advantageous if the lower and the upper layer of the projection are arranged such that the protruding edge of the upper layer of the projection with respect to the lower layer of the projection along its entire circumference has substantially the same width. Upon application of force to the lower layer of the projection thus the upper layer of the projection is uniformly stressed, whereby damage to the upper layer is prevented.

It may also be provided that the shoe sole has a length Y and a width Z, wherein a center M of the projection substantially 40% of the length of the shoe sole from the rear end of the shoe sole and substantially in the middle of the width Z of the shoe sole is arranged. In the course of this feature an optimal sequence of steps is supported from the heel over the outer bale, over the inner bale to the big toe base joint.

According to a further aspect of the invention, a shoe is specified with a shoe sole. Preferably, it is provided that a left shoe is constructed substantially mirror-inverted same as a right shoe. This results in a particularly simple production, since all parts must be made only mirrored and otherwise there are no specific differences between left and right shoes. It is possible with such a shoe a 3D step movement.

According to a further aspect of the invention, a device for attaching to a shoe, in particular for the construction of a shoe sole, is specified, the device having a closure provided with a closure around the shoe tether or the like and a sole body fastened thereto or fastened, which has on one side a flat contact surface on the underside of the shoe and an opposite curved contact surface.
