Abstract: A child-proof latch which prevents a child from directly accessing the latch member (arm) itself, thus rendering it extremely difficult for a child to open a cabinet secured by the latch. The latch of the invention comprises a latch member, a support for the latch member, and an actuator member for selectively moving the latch member between its extended position (in which the cabinet is prevented from opening) and retracted position (in which the cabinet is allowed to open). Mutually engageable locking surfaces are provided on the actuator and the support, such that the actuation is normally locked with the latch member in its normally extended position. In order to open the cabinet, it is necessary to first disengage the locking surfaces and then depress the actuator sufficiently to move the latch, which is biased toward its extended position, to its retracted position. As it is unlikely that a child could accomplish both tasks, the latch is extremely secure.
