Abstract

An adjustable height scaffold includes an upright and a cage for mounting a work platform on the upright. The cage has two spaced side plates on opposite sides of the upright. Two crossbars are connected to the side plates for relative movement of the crossbars between a captured position with the crossbars spaced by a distance greater than the cross section of the upright and a release position spaced by a distance less than the cross section of the upright. The couplings joining the crossbars to the side plates prevent disconnection of the crossbars from the side plates in the captured position but allow disconnection of at least one of the crossbars from the side plates in the release position. With the upright in the cage between the crossbars, the crossbars cannot move to the release position. To allow the cage to be conveniently assembled on and disassembled from the upright, while the upright remains in a vertical orientation, the upright has at least a section of reduced cross section, allowing the crossbars to move to the release position for assembly or disassembly. The reduced cross section may be provided by a notch in the upright.
