Lever actuated compression latch

A lever operated compression latch has an elongated, hook-ended pawl carrying a longitudinal slot, and is cam guided and pin rotated while translated to engage and withdraw from a keeper cup. The compound movement of the pawl includes a lateral translation towards the keeper cup while rotating there into, followed by a lateral withdrawal to exert a compression force between the latch body which is attached to a door and the keeper cup which is attached to a door frame. A series of interconnected links is operated by a lever handle to fold into one another to provide a compact envelope when the latch is closed and to expand outwardly to open the latch and disengage the pawl from the keeper when operated by the lever. Of this series of links, a pair of release links operates in contact with one another, and rotates on respective individual pivot points to extend outwardly from the latch envelope to engage a striker plate portion of the keeper cup. This striker engagement causes the release links to push the latch and the door from a sealing engagement with the keeper and door jamb for a short distance, prior to the latch and the door thereafter being fully opened. This striker engagement of the release links also causes the latch links to fold inwardly which rotates and translates the pawl into keeper engagement and compression. This operation is facilitated with a floating spring having one end operating as a pivot member. A detent engages one of the links to provide a physical indication to the handle lever between the hard closed position and the closed about to open position.
