Abstract
Abstract A toe stop has a flat floor-engaging surface disposed at such an angle to a mounting stud that it engages flat against the floor when the skate is tipped forwardly. The portion having the floorengaging surface is molded of relatively soft plastic having a high coefficient of friction, and the portion in which the mounting stud is embedded is formed of relatively hard plastic with a lower coefficient of friction.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
97 words
A toe stop for roller skates comprising a solid body having an upper portion bounded on its top side by an upper surface, and a stud embedded in said upper portion and projecting generally upwardly from said upper surface, and a lower portion contiguous to the upper portion and bounded on its bottom side by a flat surface, said upper and lower portions being bonded to one another, said upper portion being formed of relatively hard elastomer material, said lower portion being formed of relatively soft elastomer material characterized by having a relative high coefficient of friction.
Claim 2
Dependent Claim
97 words
A toe stop for roller skates comprising a solid body having an upper portion bounded on its top side by an upper surface, and a stud embedded in said upper portion and projecting generally upwardly from said upper surface, and a lower portion contiguous to the upper portion and bounded on its bottom side by a flat surface, said upper and lower portions being bonded to one another, said upper portion being formed of relatively hard elastomer material, said lower portion being formed of relatively soft elastomer material characterized by having a relative high coefficient of friction.
Claim 3
Dependent Claim
57 words
A toe stop as claimed in claim 1, said upper and lower portions being of molded water-resistant poly-urethane material, the material of the upper portion being characterized by a hardness of about 74 on the Shore D scale, the material of the lower portion being characterized by a hardness of about 90 on the Shore A scale.
Claim 4
Dependent Claim
27 words
