Abstract:
1. A fastener configured to couple two flanges together, the fastener comprising: a pin including a head and an elongate shank extending from the head to a lower end, the shank including an elongate slot disposed between the head and the lower end; a wedge sized so that at least a portion of the wedge may extend through the elongate slot, the wedge including an upper surface configured to face toward the head, a lower surface configured to face away from the head, first and second side surfaces that increase in width as defined between the upper surface and the lower surface along a longitudinal length of the wedge, and a longitudinal slot extending between the first and second side surfaces, the wedge further including a plurality of angled slots formed in at least one of the side surfaces adjacent to the longitudinal slot; at least one locking key adapted to engage the wedge when the wedge is inserted through the elongate slot, the locking key including an inner surface facing the wedge, an outer surface, an end surface facing the shank of the pin, and a transverse slot extending between the inner and outer surfaces, the inner surface further including a plurality of angled ridges adjacent to the transverse slot and configured to engage the plurality of angled slots in the at least one side surface of the wedge; and a locking bolt inserted through the longitudinal slot of the wedge and the transverse slot of the at least one locking key, wherein when at least a portion of the wedge is slid through the elongate slot in the shank, the two flanges are gripped between the head of the pin and the upper surface of the wedge, the at least one locking key is engaged with the at least one side surface of the wedge and slid upwardly until the end surface engages the shank adjacent to the elongate slot, and then the locking bolt is tightened to the wedge and the at least one locking key to hold the wedge in position.
