Abstract
A wheel housing is resiliently mounted on a skateboard truck base by means of a fastener which extends through the housing and is threaded onto a stud fixed to the base to compress a tubular cushion between the housing and the base. The fastener has a square cross-section which mates with a square bore in the cushion so that rotation of the fastener with respect to the cushion is prevented except when the retainer is manually forceably rotated to adjust the compression on the cushion.
Claims15
A truck for a skateboard or the like having a platform comprising:
- a support base adapted to be mounted to the under side of the platform;
- threaded means on said base;
- a wheel support housing;
- a resilient cushion having walls defining a bore therethrough extending between the housing and said base;
- and
- an elongated threaded retainer having a shank extending through a hole in said housing and into said cushion bore, said retainer shank having a threaded portion threaded to said base threaded means to compress said cushion and thereby resiliently mount the housing on the base, said retainer shank having an exterior portion with means thereon which mate with means on the walls of said cushion bore to prevent rotation of said retainer relative to said cushion during use of said truck, although the resiliency of said cushion permits manual forceable rotation of the retainer relative to the cushion for adjusting compression on the cushion.

A truck for a skateboard or the like having a platform comprising:
- a support base adapted to be mounted to the under side of the platform;
- a wheel support housing;
- a resilient cushion having walls defining a bore therethrough, said cushion extending between the housing and said base;
- and
- an elongated threaded retainer having a head and having a shank extending through a hole in said housing and into said cushion bore, said retainer being threaded to said base so that the retainer head transmits force to compress said cushion and thereby resiliently mounts the housing on the base, said cushion bore and said retainer having non-circular mating wall means formed to prevent rotation of said retainer relative to said base during use of said truck, although the resiliency of said cushion permits manual forceable rotation of the retainer relative to the base for adjusting compression on the cushion.

A skateboard comprising:
- a platform;
- a truck mounted on each end of said platform including a base mounted to the underside of said platform, said base having a recess formed on its surface facing away from the platform including a top wall and a plurality of straight side walls;
- a wheel support housing having an enlarged flange with a recess formed thereon having a bottom wall extending generally parallel to said base recess bottom wall and having a plurality of straight side walls;
- a pair of wheels mounted on said housing;
- a resilient cushion having one end shaped to fit snuggly within said base recess and another end shaped to fit snuggly within said housing recess;
- and
- threaded fastner fastner means compressing said cushion between said housing and said base and including means cooperating with said cushion which permits said fastener means to adjust the compression on said cushion but prevents loosening of said fastener means during operation of said skateboard.

A truck for a skateboard or the like having a platform comprising:
- a base adapted to be mounted to the underside of the platform;
- a threaded stud secured to said base and extending downwardly away from the base;
- a wheel housing including means for supporting a pair of wheels, a support leg supported by said base, and an enlarged support flange adjacent the wheel support means extending generally parallel to said base means defining a hole in said flange aligned with said stud;
- a tubular cushion of resilient material surrounding said stud and having one end of the cushion engaging said base and the other end of the cushion engaging the side of the flange facing the base;
- means on said base and said housing for preventing rotation of said cushion;
- a retainer having an elongated internally threaded shank and an enlarged head, the shank extending through said flange hole and into one end of said cushion and threaded onto said stud;
- and
- a washer made of resilient material mounted on said retainer between the retainer head and the other side of said flange, said retainer being threadably adjustable on said stud to compress the cushion and the washer and thereby resiliently mount the wheel housing on the base;
- the exterior of said retainer and the interior of said cushion having mating straight sided walls which prevent the retainer from rotating relative to the cushion unless the retainer is forceably manually rotated for adjustment purposes.
