Abstract:
A coupling apparatus for interconnecting three scaffold members comprising:a support coupler and two connector couplers for attachment to three respective scaffold members; the support coupler having a base interconnected to the connector couplers, a lever hinged to the base, and a locking device, the base and the lever defining a pocket for laterally receiving a length of a scaffold member; the two connector couplers each defining a pocket for receiving a length of a scaffold member and having a locking device; each of the locking devices being movable from a release condition, to allow a scaffold member to be positioned in or removed from the pocket, to a locked position, to secure the scaffold member in the coupler; wherein the pockets are oriented to secure three respective scaffold members at relative angles to each other; wherein the pocket of at least one of the two connector couplers is defined by a base interconnected to the support coupler and a lever hinged to the base, the base and the lever defining the pocket for laterally receiving a length of a scaffold member; and wherein the locking device of the at least one of the two connector couplers comprises: an arm hinged to the base of the at least one of the two connector couplers; the lever having an slot adapted to receive the arm; the arm defining a hole positioned to extend beyond the lever when the arm is within the slot; a wedge adapted for insertion through the hole to slidably move against the lever when the arm extends within the slot to wedge the arm within the lever whereby the scaffold member is locked within the at least one of the two connector couplers.
