Abstract
Abstract A running sole of flexible synthetic material for sports shoes, more particularly for athletics shoes, wherein, at least in the front portion of the sole, a plurality of integrally molded crossbars extend downwardly from the running surface of the sole and taper away therefrom. In order to impart an adequate grip on various surfaces, at least in some areas, roof-shaped projections extend downwardly beyond the cross bars, the projections having sharp edges extending substantially parallel to the running surface and also to the longitudinal direction of the crossbars, with the width of the bases of the projections corresponding substantially to the width of the crossbars. In a preferred construction the crossbars intersect one another and form therebetween honeycomb-like depressed areas, each individual roof-shaped projection being disposed between adjacent points of the intersection of the crossbars.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
95 words
A running sole of flexible synthetic material for sports shoes, especially athletic shoes, said sole comprising, in combination: a. a sole body having a front portion with a running surface; b. a plurality of crossbars molded to said body, said crossbars projecting beyond and tapering away from said running surface; c. a plurality of individually roof-shaped projections extending from said crossbars away from said running surface; and d. a blade-like sharp edge on each of said projections, said edges extending substantially parallel to said running surface and in the longitudinal direction of the associated crossbars.
Claim 2
Dependent Claim
95 words
A running sole of flexible synthetic material for sports shoes, especially athletic shoes, said sole comprising, in combination: a. a sole body having a front portion with a running surface; b. a plurality of crossbars molded to said body, said crossbars projecting beyond and tapering away from said running surface; c. a plurality of individually roof-shaped projections extending from said crossbars away from said running surface; and d. a blade-like sharp edge on each of said projections, said edges extending substantially parallel to said running surface and in the longitudinal direction of the associated crossbars.
Claim 3
Dependent Claim
26 words
A running sole as claimed in claim 1, wherein the base width of said projections is substantially equal to the base width of the associated crossbars.
Claim 4
Dependent Claim
42 words
A running sole as claimed in claim 1, wherein said roof-shaped projections are arranged in groups and wherein the edges of one group are arranged at a different angle to the longitudinal axis of the sole from the edges of another group.
Claim 5
Dependent Claim
40 words
A running sole as claimed in claim 1, wherein at least some of said roof-shaped projections are of stepped design effective to define a plurality of sharp edges projecting to different extents from the running surface of the sole body.
Claim 6
Dependent Claim
25 words
A running sole as claimed in clAim 1, wherein the individual shaped projections are provided in a plurality of areas spaced longitudinally of the soles.
Claim 7
Dependent Claim
29 words
A running sole as claimed in claim 1, wherein the individual roof-shaped projections are arranged in a plurality of rows extending transversely on the longitudinal axis of the sole.
Claim 8
Dependent Claim
29 words
A running sole as claimed in claim 6, wherein the individual roof-shaped projections of a row are arranged such that the sharp edges are in substantially zig zag formation.
Claim 9
Dependent Claim
76 words
A running sole as claimed in claim 1, and further comprising at least one rib extending around the periphery of said front portion, said rib being molded to said body and projecting beyond and tapering away from said running surface, further individual roof-shaped projections being provided in said rib said further projections extending beyond said rib and having a sharp edge substantially parallel to and aligned with the rib at the location of said further projections.
Claim 10
Dependent Claim
36 words
A running sole as claimed in claim 1, and further comprising thickened regions on the front portion of said sole body, supporting plates molded into said thickened regions, and spikes detachably secured to said support plates.
Claim 11
Dependent Claim
27 words
A running sole as claimed in claim 9, and further comprising an annular rib projecting outwardly from the periphery of said thickened portions and tapering away therefrom.
Claim 12
Dependent Claim
20 words
A running sole as claimed in claim 10, and further including means defining spaced apart incissions in said annular rim.
Claim 13
Dependent Claim
21 words
A running sole as claimed in claim 1, wherein the individual roof-shaped projections and/or the crossbars are of substantially triangular cross-section.
Claim 14
Dependent Claim
17 words
A running sole as claimed in claim 12, wherein said triangular cross-section is an isosceles triangular cross-section.
Claim 15
Dependent Claim
17 words
A running sole as claimed in claim 1, wherein the sole is made of a tough nylon.
Claim 16
Dependent Claim
27 words
A running sole as claimed in claim 1, wherein the crossbars are arranged substantially parallel to one another and transversely of the longitudinal axis of the sole.
Claim 17
Dependent Claim
65 words
A running sole as claimed in claim 1, wherein the crossbars are arranged in two sets, the individual crossbars of a set being parallel to one another, and the crossbars of one set being arranged to intersect the crossbars of the other set effective to form honeycombe-like depressions therebetween, and wherein said roof-shaped projections are each arranged between adjacent points of intersection of the crossbars.
