A speed skate plate having an elongate plastic member with means for securing a shoe on the top of the member and having axle anchors at the bottom of the plate, at the front and rear ends thereof. Each anchor is secured to the plate by means of a resilient connection permitting limited rocking of the anchor and has a pivot spur with a ball on the end thereof engaged in a socket formed in the plate. At the front of the plate a clamp is provided which is formed partially by the plate and partially by an additional plastic member that is tightly secured to the side of the front of the plate. A through threaded passageway in the clamp carries the stud of an elastomeric nose piece. The socket for the ball of the spur of the front anchor is deeper than the prior art and that portion of the plate is strengthened by side gussets. The nose piece stud has a pilot to prevent cross threading of the stud during installation.
A mounting for a roller skate especially for speed use, said mounting including an elongate plastic plate having a generally rectangular cross section, a pair of notches adjacent the front and rear ends of the plate facing downwardly, means in the notches for enabling the securement of a shoe to the top edge of the plate, an axle anchor in each notch, each axle anchor having a resilient securement with the plate to provide for limited lateral movement of the axle anchor and each anchor including a spur having a ball on the end thereof, each ball being engaged in a respective socket formed in said plate, at least the front notch having side gussets downwardly depending from said plate closing off a portion of the notch and to provide a socket containing a portion of said spur and substantially deeper than that of the rear notch to prevent accidental withdrawal of the spur from said socket in the front notch, and a toe piece secured to the front end of the plate.
A mounting for a roller skate especially for speed use, said mounting including an elongate plastic plate having a generally rectangular cross section, a pair of notches adjacent the front and rear ends of the plate facing downwardly, means in the notches for enabling the securement of a shoe to the top edge of the plate, an axle anchor in each notch, each axle anchor having a resilient securement with the plate to provide for limited lateral movement of the axle anchor and each anchor including a spur having a ball on the end thereof, each ball [and a portion of said spur] being engaged in a respective socket formed in said plate, a clamp in the front end of the plate having a through threaded passageway therein arranged at an oblique angle relative to the normal horizontal plane of the skate, an elastomeric toe piece having a threaded stud connected thereto, the threaded stud being engaged in said passageway and said stud having an unthreaded extension on the inner end thereof which extension has a diameter substantially the same as the root diameter of the stud thread so as to serve as a passageway pilot for the stud and wherein said extension engages said passageway to provide leverage preventing said stud from breaking out of said passageway.
A mounting for a roller skate, especially for speed use, comprising:
A toe piece assembly for adjustable projection from a roller skate, comprising:
