Abstract
Abstract An outsole for sports shoes comprising a carrier element (1) of relatively hard material and relatively soft sole portions (2, 3) which are secured to the carrier element on the outward side thereof. The carrier element (1) comprises a sole plate (11) which is stiffened by stiffening wells which are disposed approximately perpendicular to the surface of the plate and which substantially follow the contour of the edge of the sole. To provide for deformability of the carrier element (1), in the shank region (4) the height of the stiffening walls (13, 14) is at least locally markedly lower than in the heel region of the sole plate (FIG. 1).

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
171 words
An outsole for shoes having a front sole region, a shank region and a heel region, comprising a sole plate of an elastically flexible hard plastics material, the sole plate having an upper surface and a lower surface and an edge defining the contour of the outsole, stiffening wall means on said edge projecting approximately perpendicularly with respect to at least one of said upper and lower surfaces and having at least one portion of minimum height, said portion of minimum height being in said shank region, and sole portions of a yielding plastics material softer than said sole plate material, said sole portions being connected to said lower surface of the sole plate within that portion of said stiffening wall means projecting downwardly with respect to said lower surface, said sole portions further projecting downwardly over said wall means, whereby said sole plate forms a carrier element for said sole portions and said portion of minimum height provides pronounced flexibility of said shank region in regard to torsion and bending.
Claim 2
Dependent Claim
171 words
An outsole for shoes having a front sole region, a shank region and a heel region, comprising a sole plate of an elastically flexible hard plastics material, the sole plate having an upper surface and a lower surface and an edge defining the contour of the outsole, stiffening wall means on said edge projecting approximately perpendicularly with respect to at least one of said upper and lower surfaces and having at least one portion of minimum height, said portion of minimum height being in said shank region, and sole portions of a yielding plastics material softer than said sole plate material, said sole portions being connected to said lower surface of the sole plate within that portion of said stiffening wall means projecting downwardly with respect to said lower surface, said sole portions further projecting downwardly over said wall means, whereby said sole plate forms a carrier element for said sole portions and said portion of minimum height provides pronounced flexibility of said shank region in regard to torsion and bending.
Claim 3
Dependent Claim
24 words
An outsole according to claim 1 characterised in that the stiffening wall means (14, 17) project upwardly and downwardly beyond the sole plate (11).
Claim 4
Dependent Claim
31 words
An outsole according to claim 1 or claim 2 characterised in that the height of the stiffening wall means (14, 17) decreases in the heel region towards the apex line (5).
Claim 5
Dependent Claim
33 words
An outsole according to claim 1 characterised in that in the front sole region the stiffening wall means (13, 16) have grooves (15) to control the local deformability of the carrier element (1).
Claim 6
Dependent Claim
37 words
An outsole according to claim 1 characterised in that the sole plate (11) is provided at least in the heel region with one or more apertures (19) in which the sole portion (3) disposed therebeneath is exposed.
Claim 7
Dependent Claim
48 words
An outsole according to claim 1 characterised in that the sole portions (2 and 3) arranged in the front sole region and the heel region respectively of the carrier element (1) are separated from each other and keep the shank region (4) of the carrier element substantially free.
Claim 8
Dependent Claim
20 words
An outsole according to claim 6 characterised in that a separate sole portion is arranged in the shank region (4).
Claim 9
Dependent Claim
71 words
An outsole according to claim 1 characterised in that provided in the shank region is a projection (32), which extends in the longitudinal direction of the sole and which is connected to the underside of the sole plate (11), of one of the sole portions (2, 3) which are arranged in the front sole region and in the heel region respectively, said projection being substantially narrower than the carrier element (1).
