Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
95 words
A sports shoe including a sole comprising a resilient, flexible, soft, plastic material having substantially similar properties as PVC with respect to deformability and elasticity, ground engaging projections comprising a wear-resistant material which is relatively harder than said sole, and having substantially similar properties as polyurethane with respect to deformability and elasticity on the sole, a resiliently compressible annular member disposed between the sole and a surface portion of each said projection, fitments formed integrally with said sole, and means on each of said projections and said fitments to secure the projections on the fitments.
Claim 2
Dependent Claim
95 words
A sports shoe including a sole comprising a resilient, flexible, soft, plastic material having substantially similar properties as PVC with respect to deformability and elasticity, ground engaging projections comprising a wear-resistant material which is relatively harder than said sole, and having substantially similar properties as polyurethane with respect to deformability and elasticity on the sole, a resiliently compressible annular member disposed between the sole and a surface portion of each said projection, fitments formed integrally with said sole, and means on each of said projections and said fitments to secure the projections on the fitments.
Claim 3
Dependent Claim
30 words
A shoe as set forth in claim 1, wherein each fitment is screwthreaded, and each said projection is adapted to be screwed on to a screwthreaded fitment on the sole.
Claim 4
Dependent Claim
23 words
A shoe as set forth in claim 1 wherein said annular member is disposed in a recess in the surface of the sole.
Claim 5
Dependent Claim
14 words
A shoe as set forth in claim 1 wherein said annular member comprises rubber.
Claim 6
Dependent Claim
81 words
A sports shoe including a sole comprising a resiliently flexible plastic material, ground engaging projections comprising a wear-resistant material on the sole, a resiliently compressible annular member disposed between the sole and a surface portion of each said projection, said surface portion of each said projection being of a generally frustoconical configuration which tapers inwardly towards said sole, fitments formed integrally with said sole, and means on each of said projections and said fitments to secure the projections on the fitments.
Claim 7
Dependent Claim
81 words
A sports shoe including a sole comprising a resiliently flexible plastic material, ground engaging projections comprising a wear-resistant material on the sole, a resiliently compressible annular member disposed between the sole and a surface portion of each said projection, said surface portion of each said projection being of a generally frustoconical configuration which tapers inwardly towards said sole, fitments formed integrally with said sole, and means on each of said projections and said fitments to secure the projections on the fitments.
Claim 8
Dependent Claim
23 words
A shoe set forth in claim 5 wherein said annular member has a recess configuration complementary to said frustoconical configuration of said projection.
