ABSTRACT:
A caster for vertically adjustable beds, and the like, includes a brake assembly for locking the wheel in place. A brake arm is pivotally mounted in the housing of the caster, and includes one end adapted to abut and frictionally engage the periphery of the caster wheel to form a rotary lock. The other end of the brake arm engages a vertically translating portion of the adjustable bed, and thereby rotates the brake arm between the locked and unlocked positions. A swivel lock is disposed between the caster housing and the bed leg, and is also actuated by vertical bed translation, whereby both caster swivel and rotation are automatically controlled by adjusting the elevation of the bed.
