An improved caster assembly is provided having a load-bearing bushing rotationally disposed in a caster body and including at least one grooved recess about its perimeter wall. As the bushing rotates relative to the caster body, the grooved recess acts to dislodge dirt and particulate matter disposed between the outer surface of the perimeter wall of the bushing and the inner surface of the bore in the caster body. Rotation dislodges the particulate matter where gravity causes it to fall downwardly away from the bushing where it is displaced from the caster assembly through an open end of the caster body or suitable debris outlet.

Swivel caster assembly

In a gate or similar closure suitable for temporary and quick installation across a passageway comprised of a vertical barrier, frame, and pivotable gate within the frame, a locking apparatus is provided which allows quick and easy width changes of the closure within various widths of passageways. The locking apparatus does not require disassembly from the closure in order to change the width of the passage. The locking apparatus includes rail engaging hooks which wrap substantially circumferentially around the rails of the vertical barrier. The closure is braced in the passageway and locked into position by conventional clamp screws being tightened against the side walls of the passageway, thus forcing the rails into slots defined by the hooks.

A hub and wheel assembly for light load vehicle including baby carriages, infant strollers, wheelchairs and the like, the assembly having tandem wheels and a shock absorbing member in a trailing link suspension configuration. The assembly includes a wheel locking mechanism to lock one or both wheels into a secured position preventing the wheels from rolling about the axle. The wheel assembly incorporating a thrust bearing system to provide smooth and controlled swiveling relative to the vehicle body or frame and eliminates creeping and wobble. A swivel lock mechanism is also provided to allow the user to lock the tandem wheel assembly in a angular position relative to the vehicle body thereby preventing swiveling about the longitudinal axis of the swivel base housing. Each wheel is mounted to the axle in tandem using two low friction bearings and having a low-profile tire mounted to a rim with a reflective area for increasing safety in low elimination environments.
