ABSTRACT:
The assembly is for use with closures located in top and bottom tracks, wherein at least one of the closures is slidable in the tracks between an open and a closed position. The assembly includes an elongated rod member which is swingably attached to the top track and has up and down positions. The assembly is designed such that when the rod member is in the down position, it extends between the edge of the slidable closure and the side of the opening in which the closures are located. This prevents the slidable closure from being moved from the closed to the open position. The security latch assembly also includes a latching assembly which is attached to a wall adjacent to the closures. There is an extension member which is attached to the rod member and extends beyond the closures to the latching assembly. The extension member engages the latching assembly and holds the rod member in either the up or down position. In certain embodiments, if the invention is employed with two slidable closures, the rod member has an end member attached thereto which interfaces with the second slidable closure when the rod member is in the down position and prevents the second closure from being slid within the tracks. In yet other embodiments, the assembly is employed with a pair of security doors which can be placed adjacent and parallel to a pair of sliding glass doors.
