摘要:
A latch (10) includes a base (12), a drive shaft (100) and cam (102), and a handle (110) attached pivotally to the drive shaft (100). The handle (110) is moveable between a closed position, a pop-up position, and an open position. A slide plate (24) is attached slidably to the base (12) and engaged with the cam (102). A swivel arm (52) is attached pivotally to the base (12) and the slide plate (24). A bolt assembly (66) is attached to the swivel arm (52), and a plunger (32) is mounted within the base (12). In its closed position, the handle (110) engages the plunger (32) to engage a switch (36) and the bolt assembly (66) engages a structure. In the handle's (110) pop-up position, the plunger (32) moves to a retracted position and disengages the switch (36). When the handle (1 10) is moved to the open position, the drive shaft (100) and cam (102) are rotated so that the slide plate (24) slides and the swivel arm (52) pivots to swing the bolt assembly (66) away from the structure.

A pin latch (10) includes a guide block (12), a handle (14) having a trigger (70), and a shear pin (92) housed slidably within the guide block (12) and connected to the handle (14). The shear pin (92) includes a catch-pin (106) engageable by the trigger (70), and is slidable between an engageable position and a disengageable position when the handle (14) is moved from a closed position to an open position. Alternately, the pin latch (210) includes a bracket (316) connected to the shear pin (292) and includes a catch-pin (306), and the handle (214) is moveable to an intermediate position, such that a trigger (270) is disengaged from the catch-pin (306) and the shear pin (292) engages a stop pin (225). A guide block spring (229) acts on the stop pin (225) to retain releasably the handle (214) in its intermediate position. The guide block (512) includes a finger (513) and the shear pin (592) includes a groove (519) sized and shaped to receive the finger (513) when the pin latch (510) is in an unlatchable position.

A pin latch (10) includes a housing (12), a handle (14) attached to the housing (12), a shear pin (110) attached to the handle (14), and a finger member (118) attached to the handle (14) and the shear pin (110). The handle (14) may be set in an intermediate position between open and closed positions. Trigger pins (140) slidably engage slots (128) formed within the finger member (118) until they engage stops (135) to retain the handle (14) in its intermediate position. To further retract the shear pin (110) and move the handle (14) towards the open position, the finger member (118) is lifted and the trigger pins (140) disengage the stops (135). Alternately, the latch (10) includes a button mechanism (372) having a cross-pin (384) that engages a stop (344) formed by a slot (342) within the shear pin (330) to maintain the handle (214) in its intermediate position. To further retract the shear pin (330) and rotate the handle (214), the button mechanism (372) is depressed to disengage the cross-pin (384) from the slot (342) of the shear pin (330).
摘要:
A latch (10) includes a body (12) having a first end (13) and a second end (15), a trigger-catch-pin (64), and a pin adjustment mechanism (52) for adjusting the position of the trigger-catch-pin (64) within the body (12). The latch (10) includes a handle (32) having a first end (31) and a second end (33), an exterior surface (34), and a trigger (40). The second end (33) of the handle (32) is attached pivotally to the body (12) such that the handle (32) is moveable between a closed position, in which the trigger (40) of the handle (32) is releasably engaged with the trigger-catch-pin (64), and an open position, in which the trigger (40) of the handle (32) is disengaged from the trigger-catch-pin (64), The pin adjustment mechanism (52) is adapted to adjust the position of the trigger-catch-pin (64) within the body (12) and, in turn, the position of the first end (31) of the handle (32) relative to the body (12), so that the exterior surface (34) of the handle (32) may be positioned flush with an exterior surface of an external structure.
摘要:
A pin latch including a mounting block having a longitudinal axis, a pin slidably retained within the mounting block and having a pivot-pin, and a sliding plate slidably retained within the mounting block, the plate having a slot and a longitudinal axis extending from first and second ends thereof and perpendicular to the longitudinal axis of the mounting block. The pivot-pin engages the slot of the plate such that movement of the sliding plate along its longitudinal axis induces movement of the pin in a direction of the longitudinal axis of the mounting block. A plurality of pin latches are connected in series by links in a side-by-side fashion or around corners. One link emanating from an actuator is connected to one of the plates that the actuator can actuate the pins of all the pin latches simultaneously.
