ABSTRACT:
A latch assembly (20) for securing opposed catches (24), (24') is provided. The latch includes a housing (32); a stationary center link (34); first and second elongated links (36, 38); first and second intermediate links (40, 42); and first, second, and middle crosspins (44), (46), (48). The housing includes opposed upright side walls (52), (54) each including first and second cam slots (58), (60). The center link includes an upright slot (56). The first and second elongated links each include distal and proximal ends (70), (74) and (68), (72). The distal ends each include a hook (22), (22'). Each elongated link further includes an L-shaped slot (86), (88) located between the link's distal and proximal ends. The first and second intermediate links each include distal and proximal ends (92), (96) and (90), (94). The first crosspin (44) is movably interconnected between the housing first cam slot (58), the left elongated link L-shaped slot (86), the right elongated link distal end (74), and the first intermediate link distal end (92). The second crosspin (46) is movably interconnected between the housing second cam slot (60), the right elongated link L-shaped slot (88), the left elongated link distal end (70), and the second intermediate link distal end (94). The middle crosspin (48) is interconnected between the first and second intermediate proximal ends (90), (94) and the stationary center link upright slot (56). Movement of the middle crosspin along the upright slot causes rotation of the intermediate links and movement of the first and second crosspins in their respective slots, further causing rotation of the left and right elongated links as the first and second crosspins transverse their respective L-shaped slots.
