Abstract
Abstract A toe stop mounting in which a rib or detent projects downwardly from the toe stop support for interlocking engagement with one of a plurality of grooves formed in the upper end of the toe stop member to oppose rotation of the toe stop member in response to offcenter frictional braking forces developed thereby. The bottom of the detent is fractured in an irregular manner to increase its holding power with respect to such rotation of the toe stop member.

Claim 1
Independent Claim
257 words
In a roller skate structure, the combination comprising a resilient toe stop member for generating a frictional braking force when pressed against a surface over which it is moving, an elongate, threaded stud attached to said toe stop member and projecting therefrom for supporting the toe stop member, a plurality of indentations in the surface of said toe stop member adjacent to the projecting portion of said threaded stud, and indentations being radially spaced from one another with respect to the axis of said threaded stud, means on said roller skate structure for receiving said threaded stud to secure said toe stop member to said roller skate structure, said means including a substantially flat metallic plate having a bore formed therein for receiving said stud and at least one detent projecting downwardly therefrom and positioned to engage in one of said indentations to oppose rotation of said toe stop member about the axis of said stud, and the surface of said flat metallic plate being fractured at the bottom of said detent to divide the bottom of said detent into two spaced apart jagged edges, each of which extends substantially radially with respect to the axis of said bore, said fracture extending completely through said flat metallic plate with the radially outermost ends of said spaced apart jagged edges being supported by a substantially solid bridge of material extending circumferentially therebetween, thereby to increase the holding power of said detent with respect to opposing the rotation of said toe stop member about the axis of said stud.
