SHOE HAVING A SPINAL DISK MATERIAL DAMPING ELEMENT

Abstract

A shoe such as a pump, high heel shoe, or stiletto, has an insole and a heel. In the heel, the insole and/or the ball region, at least one damping element is integrated. The damping element has a Shore D hardness in the range of 28-33, a modulus of elasticity in the range of 28-38 MPa, and a tensile stress of 9-11 at 600% elongation. In this way, a shoe is realized that is elegantly fashioned and can be provided with a high-quality design without having to compromise on comfort and convenience.

12. The shoe according to claim 11, wherein the heel damping element has a continuous vertical recess, through which a fixing element can be introduced in order to fix the heel damping element to the two portions of the heel base member.

13. The shoe according to claim 11, wherein the portion of the heel which is constructed as a damping element is covered in an annular manner.

14. The shoe according to claim 12, wherein the portion of the heel which is constructed as a damping element is covered in an annular manner.

15. The shoe according to claim 1, wherein the heel has a frame construction of carbon.

16. The shoe according to claim 1, wherein the shoe is a pump, a high-heel shoe or a stiletto.

17. Use of a material with a Shore hardness in the range from 28 to 33, a modulus of elasticity in the range from 28 to 38 MPa, and a tensile stress of from 9 to 11 MPa at 600% extension for damping elements in shoes.

18. The use according to claim 17, wherein the material contains an admixture of different elastomers based on copolymers with polyether soft segments.

19. The use according to claim 18, wherein the shoes are pumps, high-heel shoes or stilettos.

20. Use of a material with a Shore hardness in the range from 28.5 to 29.5, a modulus of elasticity in the range from 32 to 36 MPa, and a tensile stress of from 9.5 to 10.5 MPa at 600% extension for damping elements in shoes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0040] FIG. 1 shows a ladies' shoe 1 with a high heel 2. The shoe 1 has an insole 3 which is provided with recesses 4a, 4b in the ball region and heel region. Damping elements 5a, 5b are arranged in the recesses 4a, 4b. The recesses 4a, 4b of the insole 3 are precisely so large that the damping elements 5a, 5b can be received in the non-loaded state. The insole 3 with the damping elements 5a, 5b is covered with a cover sole 9. The heel 2 comprises a base member 6 which is interrupted in the lower third by a further recess 4c. In the further recess 4c, there is arranged a further damping element 5c (heel damping element) which is secured to the base member 6 of the heel 2 and which forms the heel 2 therewith. The heel damping element 5c is covered in the example shown in FIG. 1b by an annular cover 8.

[0041] In FIGS. 2 to 5, a preferred embodiment of the individual damping elements 5a, 5b, 5c is illustrated in detail. The damping elements 5a, 5b which are intended to be arranged in the recesses 4a, 4b have a uniform thickness.

[0042] FIGS. 5a, 5b show embodiments of the BSW damping element 5, 5 according to the invention which are not arranged in recesses of the insole, but instead are themselves constructed as an insole or portion of the insole.

[0043] The heel damping element 5c has in the example shown the same cross-section as the base member 6 of the heel 2 in the region of the interruption, wherein (in contrast to the heel damping element 5c shown in FIGS. 1a, 1b) there is provided a continuous vertical recess 7 (that is to say, in the direction of the longitudinal extent of the heel 2), through which a fixing element can be introduced for fixing the two portions of the heel base member 6 to the heel damping element 5c. The insertion of the heel damping element 5c may, for example, be carried out by the base member of the heel 2 being separated all the way around, but without separating an internal metal sleeve (fixing element). The heel damping element 5c is, for example, separated at the front side with a cut and inserted into the gap between the two components of the base member 6 and adhesively bonded. The heel damping element 5c is consequently arranged in a sandwich-like manner between the two components of the base member 6 of the heel 2.
