CAGE APPARATUS RISING AND FALLING ON A WALL SURFACE

摘要

A cage or car for ascending and descending movements on a vertical wall surface of a structure in which a pin rack and a guide rail on each side of the rack are fixed on the wall surface. The cage is defined by a frame having a bottom plate and arms projecting from the frame are operably engaged with the guide rails. A rotatable driven shaft is supported in the cage in parallelism to the pins of the rack and a sprocket on the driven shaft engages the pins. An internal combustion engine on the bottom surface of the cage and a power transmitting means is provided for driving the driven shaft normally and reversely via a worm-type reduction gear from the engine.
