A multi-point sliding door latch adapted to be fitted in a single opening in the lock face of the stile of the sliding door and arranged for coaction with a keeper structure on an associated jamb and for coaction with a handle assembly mounted on the stile of the sliding door and including a tail member operated by a thumb turn or a key lock. The latch includes a unitary hollow housing sized to fit in the stile opening, a pair of vertically spaced upper and lower hooks each pivotally mounted in the housing for movement between a retracted unlatched position within the hollow of the housing and an extended latch position extending out of the hollow of the housing for latching coaction with the keeper structure; upper and lower pivot arms pivotally mounted in the housing in vertically spaced side-by-side relation between the upper and lower hooks and each adapted to receive a tail member of the handle assembly; a gang link connecting the upper and lower pivot arms so that pivotal movement of one pivot arm generates corresponding pivotal movement of the other pivot arm; an upper link interconnecting the upper pivot arm and the upper hook; and a lower link interconnecting the lower pivot arm and the lower hook.

[ I claim:] [1.] A multi-point sliding door latch adapted to be fitted in a single opening in the lock face of the stile of the door and arranged for coaction with a keeper structure on an associated jamb and for coaction with a handle assembly mounted on the stile of the door and including a tail member operated by a thumb turn or a key lock, the latch comprising:a single unitary housing adapted to fit in the stile opening and including a front wall defining aperture means and spaced side walls coacting with the front wall to define a housing hollow;a pair of vertically spaced upper and lower hooks each mounted in the housing for pivotal movement between a retracted, unlatched position within the hollow of the housing and an extended, latched position extending out of the hollow of the housing through the front wall aperture means for latching coaction with the keeper structure;adjuster means operative to separately adjust the position of each hook relative to the housing; andactuator means including an actuator pivotally mounted in the housing intermediate the upper and lower hooks and including drive means accessible proximate one of the housing side walls for driving receipt of a tail member from the handle assembly, and means operative in response to pivotal movement of the actuator in response to turning movement of the tail member to move the upper and lower hooks pivotally and in unison between their unlatched and latched positions.
