Roller skate toe stop converter
First Claim
1. An adjustable toe stop converter for converting a roller skate from use with a first toe stop having a threaded mounting stud of a given diameter and thread to use with a second toe stop having a threaded mounting stud of a diameter larger than the mounting stud of said first toe stop, said skate having on its forward end a toe stop mounting shoulder presenting a generally downwardly and forwardly facing toe stop bearing surface and defining a first threaded bore of a diameter and thread equal to that of the threaded mounting stud of said first toe stop, said toe stop converter comprising:
- (a) a counterbored member having at one end wall an upper end surface adapted to matingly abut said roller skate toe stop bearing surface and having at the opposite end wall a lower end surface, said one end wall defining a second bore having a second diameter at least equal to the diameter of said first bore in said roller skate toe stop mounting shoulder and less than the diameter of the mounting stud of said second toe stop, said opposite end wall defining a third threaded bore having a diameter and thread equal to that of the mounting stud of said second toe stop, said third bore being coaxial and communicating with said second bore to define an annular shoulder between said second and third bores;
(b) a bolt having a head of a diameter greater than that of said second bore and having a shank with a diameter less than that of said second bore, said shank having threading means adapted to threadingly engage said first bore in said roller skate toe stop mounting shoulder; and
(c) means for securing the threaded mounting stud of said second toe stop against rotation within said third bore when said stud of the second toe stop is threadingly engaged therewith, wherebysaid bolt can be inserted into said counterbored member with the bearing surface of the bolt head bearing against said annular shoulder in the counterbored member and with the shank projecting from said second bore to threadingly engage said first bore in said roller skate toe stop mounting shoulder for matingly abutting said upper end surface of the counterbored member against said roller skate toe stop bearing surface,said stud of the second toe stop can be threadingly engaged with said third bore to adjustably position said second toe stop relative to said roller skate at a distance from said counterbored member lower end surface that is variable with the amount of thread engagement, andsaid stud of the second toe stop can be secured in the desired position by said securing means.

Abstract
An adjustable roller skate toe stop converter is provided for a roller skate having a toe stop mounting shoulder defining a threaded toe stop mounting bore of a first predetermined diameter adapted to receive and threadingly engage a threaded mounting stud of a first toe stop. The converter converts the skate for use with a second toe stop having a threaded mounting stud of a diameter larger than the mounting stud of the first toe stop. The converter comprises a generally cylindrical block having on one end a small bore and on the other end a large bore, the large and small bores communicating in coaxial alignment to define an annular shoulder between them. A bolt is introduced into the block and is threaded into the toe stop mounting bore of the roller skate to mount the block thereagainst with the head of the bolt bearing upon the annular shoulder in the block. The mounting stud of a second toe stop may then be threaded in the larger bore of the block to position the toe stop at a distance from the block that is variable with the amount of thread engagement. A flexibly hinged wall portion of the block can be clamped tight against the stud of the second toe stop by means of a bolt threaded between the flexibly hinged wall and the remainder of the block for tightening and holding the hinged wall against the stud to lock the toe stop at the desired position and prevent rotation thereof.
