    Abstract: A latch (10) is usable to selectively hold a closure member such as a door (188) in a closed position. The latch includes a body (12) which has a manually engageable handle (18) on a front side thereof. A shank (30) is in rotationally movable connection with the handle. The shank extends through the body and into an indexing cam bore (58) on the back side of the body. The shank is both axially and rotationally movable about a cam bore axis (62). An indexing cam (88) is connected to the shank. The shank is in operative connection with a striker (102). The striker is rotationally movable responsive to rotation of the handle between a latched position and unlatched position when the shank is in a second axial position. When the shank is in a first axial position, the shank is held in a fixed rotational position by the indexing cam, and the striker is held in the latched position. A cam bolt (164) is movably engageable with the striker to hold the striker in the latched position. The cam bolt is in operative connection with a lock cylinder (142). The lock cylinder is rotatable in engagement with a correct key to selectively position the cam bolt.

    Abstract: A latch (10) includes a rotatable jaw (18) that engages and holds a striker (32) in a latched position. A rotatable pawl (28) in an engaged position is operative to hold the jaw in the latched position. Movement of the pawl to a disengaged position enables the jaw to move to an unlatched position and to disengage the striker. The pawl is movable from the engaged position to the disengaged position through operation of either an electrical actuator (84) or through movement of an actuating end (26) of the pawl by a cable (36).

    Abstract: A latch (202) includes a catch jaw (210) which is operative to releasably engage a post. A release pawl (212) is operative to hold the catch jaw in a latched jaw position, and upon movement of the release pawl, enables the catch jaw to move to an unlatched jaw position. In an unlocked condition of the latch, movement of a handle (206) is operative to enable the latch to change from the latched to unlatched condition. The latch includes a keylock (240) and an electrical actuator (308). Each of the keylock and the electrical actuator are operative to independently change the condition of the latch between locked and unlocked conditions.

    Abstract: An actuator (24, 528, 606, 646, 670, 700, 702) is configured to cause a latch assembly (22, 322, 422, 522, 526, 604, 644, 668, 694) to be changed from a closed condition in which an item is latched, to an open condition in which the item is unlatched. A catch jaw (30, 530, 690) is operative in a first position to engage a member (106) connected to the item when the latch assembly is in the closed condition. The catch jaw in a second position enables the member to disengage from the catch jaw when the latch assembly is in the open condition. The actuator assembly includes a drive (152, 526, 608, 706) and a gear system (157, 563, 610, 712). The gear system is operative to move a release member (174, 538, 612, 722, 764). The release member is configured to be in operative connection with the catch jaw such that the movement of the release member causes the catch jaw to be enabled to move to the second position.
