Abstract
The rotational mounting arrangements for mounting an item on a mounting surface include a stator element and rotor element cooperating together to mount the item for rotational movement relative to the mounting surface, and a locking mechanism for releasably locking the rotor element in one or more predetermined positions relative to the stator element. The locking mechanism may include one or more apertures formed in one of the stator and rotor elements, and one or more apertures or recesses in the other of the stator and rotor elements for receiving a locking component. In another form, the locking mechanism may include one or more apertures formed in one of the stator and rotor elements, and a locking component carried on the other of the stator and rotor elements.
Claims17
An arrangement for mounting an item on a mounting surface for rotational movement relative thereto, the arrangement comprising:
- a stator element fixedly associable with the mounting surface, the stator element having a plurality of stator contact surfaces;
- a rotor element securable to the item, the rotor element being mounted upon the stator element for rotation relative thereto about an axis of rotation substantially perpendicular to the plane of the mounting surface and having a plurality of rotor contact surfaces;
- and means to lock releasably the rotor element in at least one predetermined position relative to the stator element, the arrangement being such that each rotor contact surface engages a respective stator contact surface in each said predetermined position only.
In a seat provided with a mounting arrangement for mounting the seat on a mounting surface for rotational movement relative thereto, the improvement comprising:
- a stator element fixedly associable with the mounting surface, the stator element having a plurality of stator contact surfaces;
- a rotor element securable to the seat, the rotor element being mounted upon the stator element for rotation relative thereto about an axis of rotation substantially perpendicular to the plane of the mounting surface and having a plurality of rotor contact surfaces;
- and
- means for releasably locking the rotor element in at least one predetermined position relative to the stator element, the arrangement being such that each rotor contact surface engages a respective stator contact surface in each said predetermined position only.
