ABSTRACT:
Latch assembly which is free from unlocking accidents, enjoys smooth operations in locking of a wing element and in engaging of a latch arm with a socket member, and properly covers a gap between the wing element and a stationary frame. The gap is resulted from misalignment in assembling of the wing element and the stationary frame. In the assembly: a lever 3 has its base end pivoted to a base plate 1 through a pivot 4; a latch arm 5 has its base end pivoted to the lever 3 through a pivot 6; a locking plate 10 of the plate 1 has a locking socket 14 which is engaged with and disengaged from a front end of a stop member 13 fixed to a rotor 12 of a lock unit 11; a spring 15 has its coiled portion 16 mounted on the pivot 4 to bias the lever 3 upward; a support 30 carries the member 8 movable along a longitudinal direction of the arm 5; and, a spring 36 biases the member 8 away from the pivot 4.
