CONVERTIBLE CASTER ASSEMBLY

摘要

A caster assembly including a plate assembly configured to support an object to be moved; and a yoke assembly rotatably connected to the plate assembly including a caster wheel for rolling engagement with a surface. The plate assembly includes an upper plate and a lower plate coupled by a connector defining a swivel axis. The plate assembly includes a notched ring concentric about the swivel axis of rotation, the notched ring including a plurality of circumferentially spaced apart detent notches. The yoke assembly includes a yoke and a pair of spaced apart legs extending from the yoke supporting the caster wheel, the yoke disposed between the top and bottom plates and rotatable about the swivel axis. A lock assembly mounted to the yoke includes a bolt movable between an unlocked swivel position and a locked position in which the bolt engages a selected one of the plurality of detent notches.

1. A caster assembly comprising:
a plate assembly configured to support an object to be moved; a yoke assembly rotatably connected to the plate assembly including a caster wheel for rolling engagement with a surface;the plate assembly including an upper plate and a lower plate coupled by a connector, a longitudinal extent of the connector defining a swivel axis of rotation of the yoke assembly with respect to the plate assembly, the plate assembly including a notched ring concentric about the swivel axis of rotation, the notched ring including a plurality of circumferentially spaced apart detent notches;
the yoke assembly including a yoke and a pair of spaced apart legs extending from the yoke, the yoke disposed between the top and bottom plates and rotatable about the connector with respect to the swivel axis of rotation, the pair of legs supporting the caster wheel for rotation about a wheel axis of rotation transverse to the swivel axis of rotation; and a lock assembly mounted to the yoke including a bolt movable between a first unlocked position and a second locked position, in the second locked position of the bolt, the bolt engaging a selected one of the plurality of detent notches of the ring of the plate assembly inhibiting relative rotation of the yoke assembly with respect to the plate assembly about the swivel axis of rotation and in the first unlocked position of the bolt, the bolt spaced from the plurality of detent notches of the plate assembly permitting relative rotation of the yoke assembly with respect to the plate assembly about the swivel axis of rotation.
