This invention relates to a locking gimbal, 'More specifically, the invention relates to a locking gimbal for: automatically locking a gimballed object against' motion arising from an external force applied thereto; and automatically releasing the gimballed object on removal of the external force. The locking gimbal includes a first object pivotable about a first pivot axis, a second object movable along an arc centred substantially at a second axis, a locking member and. a locking formation. The first object defined a first reference axis passing through the first pivot axis and a centre of gravity of the first object, -whereas- the second object defines a second reference axis passing through the second axis and a centre of gravity of the second object. The first and second objects are movable relative to one another between a first aligned condition, wherein the first and second reference axes are substantially aligned, and a second displaced condition, wherein the first and second reference axes are angularly displaced relative to one another. The locking formation, actuated by displacement: between the first and second objects, is radially movable, relative to the first pivot axis between engaged and disengaged positions, wherein: (i) in the first aligned condition, the locking formation Is in a disengaged position and spaced from the locking; member, permitting rotation of the first object about the first pivot axis; and (ii) in the: second displaced condition, the locking formation is in an engaged position and In contact with the locking member thereby preventing rotation of the first object about the first pivot axis. |
