    Abstract: A caster assembly is provided which may include an attachment means for attaching the caster assembly to a base of an object, a caster yoke, and a cam assembly operable in at least three states. The caster yoke is operable to swivel relative to the attachment means. The cam assembly may include an actuating means for operating the cam assembly, a swivel lever mechanism and a brake lever mechanism in communication with a cam. When in a first state, the wheel rotates freely and the caster yoke swivels freely. When in a second state, a first swivel brake is engaged by the swivel lever mechanism to lock the caster yoke in a predetermined orientation while the wheel is allowed to rotate freely. When in a third state, a wheel brake is engaged by the brake lever mechanism to stop the wheel from rotating freely and a second swivel brake is simultaneously engaged to stop the caster yoke from swivelling.

    Abstract: The invention consists of a caster comprises a yoke having a weight transferring tab and a wheel with groove for receiving the tab. Preferably, the yoke and wheel are made out of plastic, and in some embodiments two different types of plastic. A tab and groove helps transfer the weight of the load on the castor away from the arms of the yoke and onto the wheel. In a preferred embodiment the plastic wheel is molded so as to include a shaft on either side that snap into receiving holes in the yoke, thus avoiding the need for separate axel and rivets.

    Abstract: A castor includes a suspension unit, a castor body, a wheel unit, and a brake unit. The suspension unit includes an upright fixing bolt and a locking member. The wheel unit includes two rollers. The brake unit includes a positioning block, a sliding block, a biasing member, a drive member, and a braking pin. Thus, when the drive member of the brake unit is pressed, each of the rollers of the wheel unit is braked by and locked onto the castor body, and the castor body is locked onto the fixing bolt simultaneously, thereby locking the castor exactly and stably.
