Abstract:
A water seal system is provided for a latch assembly that comprises a housing having a receptacle in which a handle extends therein. A trigger extends from the handle through an aperture in the receptacle to a latching mechanism on a rear side of the housing. The trigger is operative to cause the latching mechanism to operate, responsive to movement of the handle. The water seal system includes a gasket mounted to a metal backing plate, with slots extending through the backing plate and gasket. The trigger extends through the slots such that the backing plate abuts a stop surface of the trigger. Movement of the handle from the extended position to the retracted position is operative to cause the stop surface to urge the backing plate to compress the gasket adjacent portions of the receptacle that extend around the aperture.
Abstract:
An actuator (24, 528, 606) is configured to cause a latch assembly (22, 322, 422, 522, 526, 604) 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) 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) and a gear system (157, 563, 610). The gear system is operative to move a release member (174, 538, 612). 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.
Abstract:
A latch, latching system and other components are disclosed that are particularly well suited for use with the heavy doors of armored military vehicles. Some component embodiments are usable in normal and emergency modes to provide access, entry, egress and rescue through vehicle door openings. Included among the disclosed components are latches having separate operating components that can be used to retract spring projected latch bolts and that usable advantageously in pairs and readily reconfigurable for use on left, right, front and rear doors of a vehicle at locations where door thicknesses differ. Also disclosed are operating linkages intended to extend exteriorly of door armor to turn shafts to operate latches situated interiorly of the door armor.
Abstract:
A latch (10,120,200) includes a rotatable jaw (18, 124, 204) that engages and holds a striker (32,128,210) in a latched position. A rotatable pawl (28, 132, 214) 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, 152, 236) or through movement of an actuating end (26, 142, 224) of the pawl by a cable or similar mechanical connector (36, 246).
Abstract:
A latch is usable for latching and automatically unlatching a lid operative to close a bin of a waste container. The latch includes a release weight that is moveable responsive to gravity from a first position to a second position to cause the latch to disengage from a release mechanism when the latch is rotated to one or more angular positions in a dump angular orientation. The latch and release mechanism are held in latched engagement when release slide bolts and latch slide bolts are engaged in extended positions. Movement of the release weight causes the latch slide bolts to move to retracted positions to enable disengagement of the release slide bolts and latch slide bolts. A release knob is operative responsive to manual movement in two different directions to enable the latch and release slide bolts to disengage.
Abstract:
A latch is usable to latch and automatically unlatch a lid of a waste container. The latch includes a release weight that moves responsive to gravity in a housing from a first position to a second position to cause the latch to disengage from a release receptacle when the latch and the waste container are oriented in a dump angle orientation. The latch includes a rotary damper in the housing that controls movement of the release weight in the housing such that an amount of time for the release weight to move responsive to gravity from the first position to the second position is slower than the amount of time the release weight would move responsive to gravity from the first position to the second position in the housing absent the effect of the rotary damper on the release weight.
