Abstract
A lock for a sliding door includes front and rear housing members that clamp front and rear faces of a door panel adjacent an opening that is formed through the door panel. Aligned cavities in the front and rear housing members cooperate with the opening to provide a compartment that mounts a latch bolt member for forward and rearward movement. The latch bolt member has a rearwardly extending formation that projects through a hole formed in the rear housing member for selectively engaging structure located behind the door to releasably latch the door in its closed position. An operating mechanism connects with the latch bolt member and includes components that extend forwardly and rearwardly through aligned openings formed through the front and rear housing members to enable the latch bolt member to be moved forwardly and rearwardly between unlatched and latched positions, and to releasably retain the latch bolt member its unlatched and latched positions. The operating mechanism preferably includes a forwardly facing lock cylinder housed in a forwardly facing push button, and a rearwardly facing foldable handle. A sleeve formation protectively surrounds portions of the push button. Weatherproofing seals are provided between selected relatively movable components.
