Outsole With Tangential Deformation

Abstract

An outsole, especially for sports shoes, that can be formed with a large amount of elastic deformability even in the tangential direction towards the front and the back, enabling a good cushioning effect even when the tread of the foot is inclined and somewhat slipping. Beyond at least one critical deformation in the deformed region, the sole remains essentially rigid in relation to tangential deformation. In this way, the runner has a secure footing on the respective tread point. The runner can push off from the tread point without losing ground and a swimming effect on the sole is prevented. The elastic deformability of the sole also in the tangential direction is caused by at least one first element, and the rigidity of the sole in relation to tangential deformation beyond the at least one critical deformation, in addition to the degree of the at least one critical deformation in the deformed region is due to at least one second element. So that the first and second elements can be independently designed, dimensioned and produced, there are extensive structuring, formation and variation possibilities. Certain areas in the heel and/or the ball region of the sole can be varied by the at least one first element, and certain areas by the at least one second element, in the longitudinal direction.

Description

TECHNICAL FIELD[0001]The present invention relates to an outsole, especially for sport shoes, which is elastically deformable also forwards and backwards in the tangential direction and is essentially stiff with respect to tangential deformation only beyond a critical deformation in the region deformed so far.[0002]Deformation in the tangential direction is understood here to be a deformation, brought about, for example, by shearing, in a direction tangential and / or parallel to the two-dimension of extent of the outsole or its tread. Deformations in a direction perpendicular to the two-dimensional extent of the outsole or its tread, caused, for example, by compression, must be differentiated from this. Tangential directions coincide approximately with horizontal directions and perpendicular directions with vertical directions on a horizontal substrate.PRIOR ART[0003]Elastically yielding outsoles are known in large numbers in different constructions, elastic materials of different ha...

AI Technical Summary

Problems solved by technology

Most of the running shoes for sports purposes, obtainable commercially at the present time, have spring characteristics, which permit cushioning primarily in the vertical direction or in the direction perpendicular to the tread with compression of the sole, which is, however, relatively stiff in the horizontal and tangential directions and not sufficiently yielding when the foot is set down obliquely at an angle.
