Preferably the latch has at least two hooks oriented in opposite directions that slide in a generally linear manner between an unlatched and latched position in response to rotation of a pair of actuators located within the latch housing. Preferably, the latch includes reinforcement blocks defining cavities with a portion of the hooks extending into the cavities when the hooks are in the latched position.

Abstract: Spring-projected latch bolt assemblies each having a retractable latch bolt component are used to upgrade commercially available lock operating mechanisms so that closures carrying the upgraded lock operating mechanisms can lock automatically when the closures reach their fully closed positions. To permit unobstructed closing of each closure, a normally extended component of each associated spring-projected latch bolt assembly retracts during a final segment of the closing of an associated closure, and snaps back to its fully extended position as the associated closure comes to rest in its fully closed position.

The container-handling arrangement further has a biasing device that is used to bias the gripper arms together to hold a portion of a container therebetween. The container-handling arrangement also has a locking element that is designed to be moved between a lock position, in which the locking element locks the gripper arms in place to prevent release of the container, and a release position, in which the locking element does not engage the gripper arms to permit release of the container.

Abstract: A door lock mechanism for an overhead door employs a sliding pin or rod that passes into the path of the rollers in the track, and obstructs the roller from movement in the direction to open the door. A spring in the door lock frame biases the sliding pin towards a proximal open position. The sliding pin has an arm that extends radially from its proximal end, and which engages retaining structure at the proximal end of the door lock frame. The arm is rotated out of engagement with the retaining structure to release the pin so it may slide proximally to an unlocked position. The pin may slide into a receiver housing mounted on a door panel.

Abstract: Sliding latches are disposed on the mounting plate of an accessory to a base member. The sliding latches are biased towards respective extended positions at which the latches engage undercuts provided in an exterior surface of the base member. The sliding latches are also biased towards their engagement in the undercuts with a force sufficient to maintain such engagement until a predetermined force is applied to either the base member or the accessory, whereupon the sliding latches move toward a retracted position and the accessory separates from the base member. The sliding latches are interconnected by cam members rotatably mounted on the mounting plate, with at least one of the cam members being directly biased toward rotation in a direction which urges the sliding latches toward their respective extended positions.

Abstract: In accordance with this invention, a releasable clamping apparatus (10) is constructed having an opening or slot (14) within which a lifting handle (28 or 30) is clamped between retaining latch portions (62, 64) and a clamp assembly (34). The latch portions (62, 64) are supported by openings (56, 58) and are retracted and extended into a slot (14) by spring biased linkage members (78, 80). These members (78, 80) are acted upon by similarly profiled cam lobes (116, 116a, 118, 118a). Dissimilarly profiled cam lobes (126, 128) of the cam member (110) act upon the clamp assembly (34), clamping a handle (28 or 30) against faces (68) of the latch portions (62, 64). The cam member (110) is coupled to a shaft (162) having an operating handle (32), with the shaft (32) also being provided with a detent assembly (202). This detent assembly (202) locks the handle (32) and the shaft (162) in "locked" positions (38 or 40) in the surface (198) of the apparatus (10), which clamps a handle (28 or 30) as described.

Abstract: A catch or lock with a cam (3) rotatable to move one or two resilient latching arms (20) at the end of which may be latching means (25) engageable on a hasp (4) to catch or lock an article. The cam (3) or casing (1) has a follower (18) which acts in a groove (15) with a ramped bottom dividing the groove into two portions and preventing the cam from being rotated from the second back to the first portion. When the cam is in a first position (X) with the follower in the first portion the latching means are held open and are inoperative for latching. The key is then inserted to move the cam so the follower is in the second portion, the cam being movable between positions (Y) and (Z) in which the latching means open and close respectively, and the key is removable in position (Z).
