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). Also, the pin (38) is pivotally secured to the body (36) so that the pin (38) may be selectively pivoted from its normal operative position to a clearance position transverse to the axes of the openings (30).

This latch device for an access panel door includes an open lever and a ratchet release lever pivotally mounted on a base plate by a first shaft, a lock lever pivotally mounted on the base plate by a second shaft, and a sliding pin displaceable between an engaged position and a disengaged potion. The release lever has first and second arms extending in a radial direction of the first shaft and connected to latch units. The lock lever shifts the sliding pin to an engaged position when the lock lever is in the unlocked position and shifts the sliding pin to a disengaged position when the lock lever is in the locked position. The sliding pin is slidably mounted in a slot formed on the first arm or the second arm.

An oven door lock for self-cleaning ovens is described. The oven door lock includes a clutch mechanism which locks and unlocks the oven door at substantially different temperatures, in particular, the lock temperature is substantially higher than the unlock temperature. The clutch mechanism comprises a thermally responsive element, a clutch, and a lock member. During heating, in a self-clean or normal cooking operation, an expanding thermally responsive element, acting upon the clutch, causes the lock member to lock the oven door. During cool down, the contracting thermally responsive element, acting upon the clutch in an opposing direction, in concert with a restraining spring, causes the lock member to unlock the oven door at a temperature substantially lower than the locking temperature.

A locking device for use with a child safety door has a press bar (24) pivotally received in a housing (21), a first latch (22) pivotable in relation to the housing (21) and having an end (222) securely engaged with a first end (242) of the press bar (24), a handle (26) pivotally received in the housing (21) and having an abutting block (263) and a second latch (23) slidably received inside the housing (21) and operatably connected with the handle (26). With such an arrangement, the press bar (24) and the handle (26) are able to control the locking/unlocking mode between the door (14) and the doorframe (10) of the safety door.

A lid latch assembly (10) for a household washing machine is disclosed which incorporates safety features which prevent damage to the latch assembly regardless of when the drum access lid of the machine is closed. The assembly includes a solenoid (22) operated locking lever (60) pivotally mounted to a bracket (12). An elongated slot (68) in the bracket defines a first fulcrum (66) about which the locking lever pivots during latching movement. A switch arm (30) must be depressed downwardly by a latching hook (84) connected to the machine lid (80) before the locking lever is movable to the latched position. A blocking tab (58) on the switch arm prevents movement of the lever to the latched position prior to downward movement of the switch arm. The elongated slot allows the locking lever to pivot about a second fulcrum defined by the blocking tab.

A lock mechanism forming part of a security system is mounted in a door or window and is completely concealed when the door or window is locked. The mechanism features a latch having a ferromagnetic portion and a nonferrous bolt in a nonferrous casing having a ledge defining an abutment. The latch is moved by the pull of an external magnet of predetermined strength movable along a predetermined path for locking and unlocking the door or window. The latch is maintained in locked position by engagement of its ferromagnetic portion with the abutment, which portion is disengaged from the abutment by the magnet.
