Abstract: A lock includes a first housing attached to a door and having an extendible latch bolt and further includes a second housing, or striker, attached to an adjacent doorjamb and including an inner slot for receiving the latch bolt. The latch bolt includes a generally flat inner surface and a convex outer, leading surface in facing relation to the adjacent doorjamb. Disposed on a distal end portion of the latch bolt's inner flat surface is a first projection, or tang, while disposed on an outer edge of the striker's inner slot is a second projection, or lip. With a given amount of "play", or free movement, of the door relative to the doorjamb, the door may be opened by urging the door outward and actuating a release knob in the first body for withdrawing the latch bolt from the striker and into the first housing, with clearance provided between the latch bolt's tang and the striker's inner lip.

Abstract: A latch catch has a pair of rotors 24, 25 and a pair of spring biased spreader plates 30,31 that bear stops 30', 31' which straddle the rotors. Springs 33 bias the spreader plate stops 30', 31' towards a position stopping the rotors from moving to their unlatched positions. Hand levers 40, 41 are provided for manually forcing the spreader plate stops to a position allowing the rotors to move to their unlatched positions.

Abstract: A latch assembly for actuating a bolt assembly for a door is provided. The latch assembly includes a housing and a cavity extending partially therein. The housing includes a guide track for receipt of track engaging members extending from a slider. The slider is movable between a first position whereby the bolt assembly is actuated and a second position whereby the bolt assembly is not actuated.

Abstract: An apparatus for locking a case having a first part and a second part that close together along a first edge of the first part and a second edge of the second part, comprising a housing portion mountable in the first part adjacent the first edge, a latch portion positioned in the housing portion and capable of slidable movement within the housing portion from a first position to a second position displaced from the first position, and a biasing spring positioned between and adapted with respect to the housing portion and the latch portion to bias the latch portion into the first position. A catch is connected to the second part of the case and extends in a direction from the second edge of the second part toward the first edge of the first part.

Abstract: A door latch mechanism with a vertically linearly translatable operating member that is manually movable to unlatch a door. The mechanism, which includes a locking assembly, is locked by rotational movement of the operating member. A foil member connects with the operating member centrally and has ends wound into chambers. The foil, movable with the operating member vertically, closes a slot in which the operating member moves. The connection of the operating member with the foil permits rotational movement for locking. A rotational latch cooperates to hold the operating member in its rotated, locked position, against the bias of springs urging unlocking rotational movement of the operating member.
