A sliding door latch system and method is disclosed herein. The sliding door latch system is used to prevent movement of a sliding door between a closed position and an open position relative to a fixed door frame. The device may be installed as a secondary safety latch on a sliding door having a primary latch that is located at an elevation within the reach of the child. The device may be installed at an elevation above the reach of the child, but readily within the reach of an adult user. The sliding door latch includes a latch arm located outside the sliding door to simplify installation. The latch arm is user-locatable in a latched position, a momentarily released position, and a held-in-release position.

A latch having a support bracket having a guide slot formed in a bottom surface. A linkage at least partially received within the guide slot and a handle coupled to the linkage transitionable between an open position and a closed position. A pin releasably coupled to the linkage such that when the handle is in the closed position the pin is coupled to the linkage and in the open position the pin is removable from the linkage. As the handle transitions from the open position to the closed position, the linkage moves within the guide slot.

An actuating system for an actuatable door that comprises at least one latching device with a latching hook that is adapted for locking the actuatable door in a closed position, the latching hook being pivotally mounted to an associated pivot bearing and connected to a pivotable mechanical transmission element via a coupling link, which is pivotally mounted to the latching hook and to the pivotable mechanical transmission element, the pivotable mechanical transmission element being coupled to a rotatable latching shaft, wherein rotation of the rotatable latching shaft in operation results in pivoting of the pivotable mechanical transmission element and pivoting of the latching hook around the associated pivot bearing, wherein the pivotable mechanical transmission element is mounted onto the rotatable latching shaft. The invention is further related to an actuatable door having such an actuating system.
