摘要： A swivel castor assembly, includes a body having at least one rotatable wheel engageable with a floor or ground surface below the body, a brake actuable to brake or prevent rotation of the wheel, and an element for mounting the body such that it is able to swivel about a generally upright axis. A head is adapted to be mounted to prevent or restrict its rotation about the upright axis. A brake activator is mounted to the head for movement between a braking position in which it activates the brake, a neutral position in which the brake is inactive and the body is not prevented from swivelling about the upright axis, and a direction-lock position in which the body may be swivelled to one of plural selectable orientations with respect to the head at each of which the body is locked against swivelling but the brake is inactive.

摘要： 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 wheel 2 is substantially freely rotatable about the swivel axis S when the wheel 2 is rotated in the reverse direction. Rotation of the wheel 2 in the reverse direction urges the actuator element into pressing engagement with the wheel driving the coupling portion of the engagement element away from the peripheral surface of the wheel for disengagement of the engagement element from the locking element. Engagement of the engagement element 8 and the locking element 12 is only effected when the wheel 2 is rotated in a forward direction to reduce the pressing engagement.
摘要翻译：本发明总体上涉及安装在购物车的框架的下侧上的脚轮组件1。车轮组件1包括安装到车轮安装件4并可围绕其旋转轴线6旋转的车轮2。接合元件8和致动器元件10形式的锁定装置可操作地联接到车轮安装件4，用于可释放地接合锁定车轮安装件4的元件12，以限制车轮2围绕车轮安装件4的旋转轴线S的旋转。当车轮2沿相反方向旋转时，车轮2可绕旋转轴线S基本上自由旋转。车轮2沿相反方向的旋转促使致动器元件与驱动接合元件的联接部分的轮相压离开离开车轮周边表面的轮子，以使接合元件与锁定元件分离。接合元件8和锁定元件12的接合只有当车轮2沿向前方向旋转以减小按压接合时才进行。

摘要： 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.
