ABSTRACT:
A tripod for supporting a window washer's bucket or the like. The support incorporates three legs pivotally connected under a cage for receiving the bucket and pivotable between retracted co-extensive positions and spread positions angling downwardly and outwardly. The positioning of the legs is controlled by an actuator telescoped upwardly into the open bottom end of a vertical actuator tube mounted under the cage. The actuator is normally positioned in an extended position projecting downwardly beyond the bottom ends of the legs when they are in their collapsed position. Rigid coupling links are pivotally connected between the actuator an support legs such that retraction of the retractor upwardly into the tube raises the proximate ends of the links upwardly driving the lower end of the support legs radially outwardly to their support positions.
