ABSTRACT:
A composite guide rail for bellows type cameras is disclosed in which the composite rail is comprised of two rail pieces. A multi-fingered connecting insert has a base secured to the end of the first rail while the fingers conform to an inner cavity in one end of the second rail and can be slidably inserted-therein. A wedge having a threaded central bore is movably disposed between the plurality of fingers and is connected to a thumb screw by a threaded connecting rod, the thumb screw located at the opposite end of the first rail from the connecting insert. When the fingers are inserted into the cavity of the second rail and the thumbscrew turned in one direction, the fingers are expanded by the wedge being drawn therebetween such that the fingers come into pressing engagement with the walls defining the inner cavity of the second rail. When assembled, the first and second rails take on the aspect of a single rail.
