a) a housing mounted onto the upright gate post, said housing having left and right apertures therein, wherein said left aperture is disposed on a first side portion of said housing and said right aperture is disposed on an second side portion of said housing; b) a key operated lock mechanism disposed on an inside of said housing; c) a pivoted latch plate disposed inside said housing, wherein said latch plate pivots between a first, lower position and a second, upper position in response to operation of said lock mechanism, and means biasing said latch plate into said first, lower position; d) a latch bar having first and second opposing ends slidably disposed in said left and right apertures of said housing, and a plurality of spaced apart notches disposed on said latch bar, a hook disposed on said first end of said latch bar wherein said hook is adapted to partially encircle and thereby capturing a first movable gate member, each notch having a side wall intersecting a sloping bottom wall facing a distal tip end of said pivoted latch plate; e) an extended trigger arm parallel with and spaced from said latch bar, and means biasing said trigger arm in a down position, said distal tip end of said latch plate being biased into engagement with said side wall of a notch in said latch bar thereby locking said latch bar and said hook in a locking position, said trigger arm adapted to engage an overhanging portion of said distal tip end of said latch plate when said trigger arm is raised; and f) said key operated mechanism having a latch release slide to urge said trigger arm upwardly to raise said tip end of said latch plate to disengage said tip end from said notch to allow sliding of said latch bar and hook out of engagement with said first movable gate member thereby allowing said gate member to be opened. |
