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 to the selected U-shaped notch of a flange 1) that is formed integrally with the side plate portions that define the selected U-shaped notch, 2) that is connected by a tight radius bend to the side plate portions that define the selected U-shaped notch, and 3) that extends transversely so as to bridge between the pair of housing side plates.
