ABSTRACT:
A housing (14, 24) is mounted on each of two bodies. Each housing (14, 24) has an inwardly extending strut portion (16, 26) with an inner mating surface (18, 28). The mating surfaces (18, 28) are urged together to react a preload on the latch (12). The preload is provided by the tensioned engagement of a draw hook (62) and a catch pin (106). The draw hook (62) is pivotably mounted on a lever (42) that is pivotably mounted on housing (14). The catch pin (106) is slidably mounted on housing (24). The pivot axes of hook (62) and lever (42) are positioned to provide over-center latching action. A carrier (100) for the catch pin (106) has a shaft (102) that is threadedly engaged by a hollow internally threaded bolt (112). The outer end of the bolt (112) is axially engaged by a screw driver to adjust the longitudinal position of the carrier (100) along the load path to adjust the preload tensioning. Rotation of the carrier (100) is prevented by engagement of the carrier (100) in slots (142) in housing (24). The load path is generally perpendicular to the mounting surfaces of the bodies.
