ABSTRACT:
A castor wheel assembly on the underside of a shopping trolley comprises a wheel mounted to a wheel mount and rotatable about its rotational axis. A locking device including an engagement element and an actuator element is operatively coupled to the wheel mount for releasably engaging a locking element of the wheel mount to restrict swivelling of the wheel about a swivel axis of the wheel mount. The wheel is freely rotatable about the swivel axis when reversely rotated. Reverse rotation of the wheel urges the actuator element into pressing engagement with the wheel, driving the coupling portion of the engagement element away from the periphery of the wheel for disengagement of the engagement element from the locking element. Engagement of the engagement element and the locking element is only effected when the wheel is forwardly rotated to reduce the pressing engagement.
