ABSTRACT:
A concealed safety latch assembly for a medicine cabinet that has three components: a mounting plate, a latch member, and a locking member. The mounting plate has an aligning flange along its forward edge to facilitate alignment of the mounting plate upon a vertical side wall of the medicine cabinet. The latch member has a nose portion with a cam surface, an unlatching finger, and a notch is formed between them. A tongue member extends into said notch from the body of the latch member and has a reduced thickness adjacent the area where it extends from the body of the latch member. The latch member is pivotally attached to the mounting plate by a shaft passing through an eccentrically located bore on the latch member. The locking member is L-shaped with its vertical leg attached to the inside vertical wall of the medicine cabinet door. The horizontal leg has a forward cammed nose surface behind which a cutaway recess is formed for lockingly engaging the nose of the latch member. The uniqueness of the manner in which the cam surface may be captured between the nose and tongue of the latch member provides a configuration that permits the L-shaped locking member to self-align itself on the back of the medicine cabinet door.
