Swing-out workbench extension

Abstract

The swing-out workbench extension of the present invention includes a rectangular swinging platform suspended from the top of a workbench by four swinging uprights on upper and lower axles between a lower stored position and an upper extended position. The rectangular swinging platform has at least one and preferably two tool support cross members extending between the respective opposed side members thereof. A latch is provided for releasably locking said rectangular swing platform in its said upper extended position. A heavy tool is connected to at least one cross member of the rectangular swing platform and is swingable outward from a stored position to an upper extended position and locked in place for use by a latch. The tool mounted on the rectangular swinging platform is also swingable downward to a stored position upon release of the latch.
