Abstract: A retractable window latch for locking together a first and second window having interlocking meeting rails. The retractable window latch includes a latch body having a faceplate that is substantially flush with a first interlocking meeting rail. A retractable bolt disposed in the latch body extends outwardly through a slot in the faceplate. A handle is coupled to the bolt for retracting the bolt into the latch body. The bolt remains retracted while the first and second windows are open. A flexible release member is disposed behind the faceplate such that the flexible release member engages a second interlocking meeting rail when the first and second windows are closed. The second interlocking meeting rail engages the flexible release member in order to lift the retractable bolt from the slot in the faceplate. A spring forces the bolt outwardly from the latch body to secure the first and second windows together.

Abstract: An over-center toggle latch which can be integrally molded with the first and second members of a case. The over-center toggle latch includes a hinge arm that has first and second spaced ends. A first living hinge attaches the first end of the hinge arm to the first case member. A second living hinge is for coupling a lever arm to the second end of the hinge arm. An engagement member-receiving seat is formed on the second member of the case. An engagement member is mounted to the lever arm and is spaced from the second hinge. The engagement member pivotally engages the seat with the hinge arm in an over-center position with respect to the engagement member. The latch is configured for use with first and second case members that have sides and edges. When the first and second case members are secured by the latch, the edges are generally coplanar and perpendicular to the sides.

Abstract: An improved cover lock apparatus comprises a rotatable and axially slidable crank plate connected to a plurality of retractable lock rods. The crank plate is disposed between the cover and a lock plate and is slidably and rotatably mounted to the lock plate. The crank plate has two upwardly protruding lock pins oriented to engage mating holes in the lock plate and is upwardly biased against the lock plate by a spring. When the lock pins are engaged in these holes, the crank plate cannot be rotated to retract the lock rods. Before the crank plate can be rotated to retract the lock rods, the lock pins must be disengaged from the mating holes in the lock plate by forcibly pushing down on the crank plate via a special lock key to overcome the spring bias that normally holds the crank plate pins in the engaged position. Once the crank plate is pushed downward enough to disengage the lock pins, it can be rotated to retract the lock rods.

Abstract: The disclosure relates to a locking mechanism for cases, a large portion of which is contained for operation within a recess located in the lower portion of the case.

Upon pivoting to the latched position, the pawl contacts a frame to draw the closure member up against the frame under compression.

Abstract: A remote latching mechanism is provided having a connecting member, preferably a cylindrical rod, means for rotating the connecting member about its longitudinal axis, and a latch assembly connected to the connecting member for movement between latched and unlatched conditions in response to the rotation of the connecting member. The means for rotating the rod may be a handle assembly, having a handle journalled within a handle cup, and/or a socket member affixed to the end of the rod for rotation of the rod upon application of torque of the socket member. The latch assembly comprises a crank, at least one link member having over-center action, a pawl support and a pawl, all inter-connected so that upon rotation of the crank, the pawl is pivoted and slid relative to a latch housing between latched and unlatched positions.

Abstract: A rotary operated latch of the "lift and turn" fastener type is disclosed having a cam action in the handle such that when the handle is moved to a latched position, it provides a pull on the pawl to compress a door or panel against a door or panel frame, or its gasket, to provide a tight seal. An over-center action prevents accidental release. A slot and pin arrangement prevents moving the handle to a latched position, except when the pin and slot are aligned. While the pawl and handle are normally rotatable relative to a sleeve in the door or panel which carries the mechanism, the pin and slot are so located as to be incapable of sufficient axial relative movement to move the handle into a latched position, except when the pawl is rotatably positioned for movement into a latched position.

Abstract: A draw pull latch for securing two members together comprises a keeper affixed to one of the members and a second one-piece part which is composed of three segments; i.e., a base segment, an intermediate segment, and a locking segment. The base segment is adapted for being affixed to the second one of the members and the intermediate segment is flexibly connected to the base segment and the locking segment for pivotal movement of the segments about transverse axes. When in the locked condition, the intermediate segment is disposed in substantially coplanar relation to the base segment, and the locking segment is disposed in overlying relation to the base segment and the intermediate segment and to the keeper. The locking segment is detachably connected to the keeper, and the flexible connection between the intermediate and locking segments is closer to the second member than the flexible connection between the intermediate and base segments.
