Abstract:
Apparatus for rotating an elongate movable member, the member being pivotally mounted to a structure using a pivot mounted with its axis spaced from the center of gravity of the member, the member being rotated about the pivot between substantially horizontal and substantially upright positions, comprising:(a) a cam having a rotational axis adapted for alignment with said pivot and adapted for connection to the member so that when the cam rotates the member also rotates, the cam having a profile which when pulled along on its tangent creates a large moment for rotating the member from said horizontal position which moment reduces as the member rotates from said horizontal position to the upright position;(b) a first cable overlying said profile for pulling the cam along its tangent;(c) a foot operated device adapted to be located adjacent said structure for pulling the first cable; and(d) a sheath, the sheath adapted to be anchored to the structure adjacent the cam and to the foot-actuated device so that the first cable is pulled relative to the sheath by the foot-actuated device.
