Abstract
A caster assembly of the type that accommodates swivelling movement of a caster wheel including a U-shaped horn that flanks the sides of the wheel and supports the wheel axle. A swivel plate is rotatably mounted on top of the horn and is adapted to be connected to the underside of the article to be supported. This plate carries a kingpin that extends through the horn and has an annular swivel lock plate fixed to its lower end. A swivel lock assembly is provided for locking the caster selectively in one of four 90 degree positions and it is mounted on rearwardly projecting ears on the U-shaped horn. The swivel lock assembly includes a spring biased axially movable plunger mounted radially with respect to the swivel lock plate and it is selectively engageable with four ninety degree spaced recesses in the swivel lock plate. The plunger is deactivated manually by pulling a ring extending through the rear end of the plunger against the biasing force of a coil spring and rotating the ring 90 degrees and releasing it into holding recesses on a U-shaped bracket fixed to horn ears.
