ABSTRACT:
A quick-release pin latch assembly comprises a first latch member configured for locking engagement with and a second latch member. The first latch member includes a body member and a load bearing post or pin extending outwardly from the body member. The load pin has an enlarged head portion offset from the body member by a shank portion. The second latch member includes a base plate and a somewhat flexible, elongate latch plate. The latch plate is anchored at one of its ends to the base plate, wherein the latch plate is biased to remain in substantial contact with the base plate. The base plate has a pin receiving elongate opening. The elongate opening is large enough at one end to allow the head portion of the pin to pass. The elongate opening is reduced at an opposite end to receive and establish coupling engagement with the shank portion of the pin. The latch plate has a retaining hole to receive and establish coupling engagement with the head portion of the pin. The assembly is latched by inserting the pin transversely through the enlarged end of the elongate opening to cause the latch plate to flex away from the base plate, and then moving the pin laterally toward the reduced end of the elongate opening until the head portion of the pin is received within the retaining hole of the latch plate. The latch plate then resumes substantial contact with the base plate, whereby the assembly is locked.
