Abstract: The present invention relates broadly to a trolley (10) comprising trolley framework (12) having four pairs of castor wheel assemblies (14A) to (14D). Each of the pair of castor wheel assemblies such as (14A) includes a swivel castor assembly (16) and a castor assembly (18) of a fixed directional orientation. The swivel castor assembly (16) includes a castor wheel (28) rotationally mounted to a castor support bracket (30). The castor (28) rotates about a rotational axis provided by axle bolt (32). The swivel castor assembly (16) also comprises a swivel shaft (34) about which a castor support bracket (30) together with the castor wheel (28) moves in a swivelling motion. The swivel shaft (34) is connected to a tilting element (36) which is operatively coupled to the trolley framework (12).

Abstract: The present invention relates generally to a castor wheel assembly (1) fitted onto the underside of the frame of a shopping trolley. The wheel assembly (1) comprises a wheel (2) mounted to a wheel mount (4) and rotatable about its rotational axis (6). Locking means in the form of an engagement element (8) and an actuator element (10) is operatively coupled to the wheel mount (4) for releasably engaging a locking element (12) of the wheel mount (4) to restrict swivelling of the wheel (2) about a swivel axis (S) of the wheel mount (4). The engagement of the engagement element (8) with the locking element (12) is only effected when the wheel (2) is rotated in a forward direction such that the wheel (2) is substantially freely rotatable about the swivel axis (S) when the wheel (2) is rotated in the reverse direction.
