Abstract
A slam-capable rotary latch employs a single rotary jaw that is releasably retained in its latched position by a rotary pawl, with the latch having a pair of spaced housing side plates that sandwich the rotary jaw and the rotary pawl, with the side plates defining aligned first and second U-shaped notches that cooperate with a third U-shaped notch formed in the rotary jaw for concurrently receiving and latchingly retaining within the confines of the first, second and third U-shaped notches a suitably configured strike formation, with housing side plate portions that define a selected one of the first and second U-shaped notches being rigidified and strengthened by the close proximity presence of a flange 1) that is formed integrally with side plate portions that define the selected notch and 2) that extends transversely to bridge between the housing side plates at a location near the first and second U-shaped notches. Improvements include housing side plate formations that aid in positioning, guiding and accommodating movement of relatively movable components, and improved connections formed between non-movable components.
