  • Patent number: 7182308
    Abstract: An assembly (20) for releasably interconnecting a pair of concrete form panels (22, 24) having adjacent, apertured walls (30) is provided which completely eliminates loose parts and significantly reduces panel setup and knock-down times. The assembly (20) includes an elongated pin (38) axially shiftable between extended and retracted positions, as well as an elongated connection arm (88) of length to bridge the adjacent walls (30) and engage the remote surface of the wall (30). An operating mechanism (42) is operatively coupled with pin (38) and arm (88). A latch assembly (96) serves to releasably maintain the pin (38) and arm (88) in their respective positions. Preferably, the pin 38 is mounted on a body (36) shiftable along a track (46); the latch assembly (96) is also supported on the body (36) to insure that the operating mechanism (42) can be properly latched in the retracted and extended positions of the pin (38).
