A latch assembly, comprising: an operating lever (3) having a base-end portion pivoted to bearing plate portions (2, 2) of a base plate (1) through a first pivot (4), the bearing plate portions (2, 2) projecting from a one end portion of said base plate (1); a latch arm (5) having a base-end portion
A latch assembly, comprising: an operating lever (3) having a base-end portion pivoted to bearing plate portions (2, 2) of a base plate (1) through a first pivot (4), the bearing plate portions (2, 2) projecting from a one end portion of said base plate (1); a latch arm (5) having a base-end portion pivoted to an intermediate portion of said operating lever (3) through a second pivot (6); said second pivot (6) and said first pivot (4) being so arranged that said base plate (1) is closer to said second pivot (6) than to a straight line drawn between said first pivot (4) and an engaging-end portion (8a) of a socket member (8) in a locking condition in which a front-end hook portion (7) of said latch arm (5) engages with said engaging-end portion (8a) of said socket member (8); said base plate (1) being provided with a pair of guide plate portions (10, 10) in its other end portion, said guide plate portions (10, 10) being inserted in a rear-surface side cavity portion (9) of said operating lever (3); said guide plate portions (10, 10) being provided with a pair of slots (13, 13) extending in a longitudinal direction of said base plate (1), in which slots (13, 13) a pair of projecting plate portions (12, 12) of a lock plate (11) are slidably inserted; a push plate (14) having a base-end portion disposed in the vicinity of a finger-engaging end portion (3a) of said operating lever (3), said push plate (14) being fixedly mounted on said lock plate (11); said push plate (14) being provided with a spring-support plate portion (15) in a front-end portion, said spring-support plate portion (15) being slidably inserted in a through-hole (17) of a spring-support plate (16) projecting from an intermediate portion of said base plate (1); a coil spring (18) mounted on said spring-support plate portion (15) of said push plate (14) with the support plate portion (15) being inserted through the coil spring (18), said coil spring (18) being compressed between an end surface (14a) of said push plate (14) and said spring-support plate portion (16) to bias said push plate (14) so that each of said projecting plate portions (12, 12) abuts against a far one surface (13a) of inner wall surfaces (13a, 13b) of each of said slots (13, 13), said first pivot (4) being farther away from said far one surface (13a) of the inner wall surfaces (13a, 13b) than from an other one surface (13b) thereof; a socket-member plate (19) fixedly mounted on said operating lever (3) and being provided with a pair of locking plate portions (20, 20) projecting into the rear-surface side cavity portion (9), said locking plate portions (20, 20) being provided with a pair of locking notches (21, 21) in side edges of the locking plate portions, said locking notches (21, 21) being engaged with and disengaged from said projecting plate portions (12, 12) of said lock plate (11); and each of said locking plate portions (20, 20) being provided with an oblique cam surface portion (22) in a front-end portion, said oblique cam surface portion (22) being adjacent to each of said locking notches (21, 21) and brought into a slidable contact with an edge surface (12a) of each of said projecting plate portions (12, 12) of said lock plate (11) to slidably move said lock plate (11) toward the other one surface (13b) of said inner wall surfaces (13a, 13b) along said slots (13, 13).
