  • Patent number: 5002081
    Abstract: The frame for a collapsible canopy is suspended on an externally threaded shaft which extends downwardly from a head in a concave socket at the free end of an overhead supporting arm. A nut which mates with the shaft beneath the frame can be rotated by way of a downwardly extending handle to move the frame into frictional engagement with the underside of the socket while urging the head against the upper side of the socket. If the angular position of the frame is to be changed, or if the frame is to be separated from the arm, the grip of the head and frame upon the socket is relaxed and the shaft is then ready to be withdrawn from an open slot of the socket.
