Abstract

See full text

A caster wheel brake and anti-swivel system for carts and other wheeled articles is operable to secure free-castering wheels against swiveling rotation about their swivel axes, and against rolling rotation along their horizontal rotation axes. The system includes a swiveling caster wheel assembly and an actuation link, with an anti-swivel actuator and a brake actuator coupled thereto. Linear movement of the actuation link causes the anti-swivel actuator to engage the anti-swivel member that rotates with the caster wheel about the swivel axis, to selectively prevent the anti-swivel member and wheel from swiveling. The actuation link's movement also urges a brake actuator to move a wheel brake and drives a braking surface into engagement with the wheel, thereby preventing the wheel from rolling at the same time it is prevented from swiveling by the pawl. Optionally, a foot-operated torque shaft and a rack-and-pinion arrangement are used to operate the actuation link.
