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.
