Multi-point sliding door latch

A multi-point sliding door latch and handle assembly adapted to be fitted on a stile of a door, comprising;

• a unitary hollow housing adapted to fit in an opening in a lock face of the stile;
• a pair of vertically spaced upper and lower hooks each pivotally mounted in the housing for movement in opposite pivotal directions between a retracted, unlatched position within the hollow of the housing and an extended latched position extending out of the hollow of the housing for latching coaction with a keeper structure on an associated jamb;
• actuator means positioned in the housing intermediate the upper and lower hooks, adapted to receive a tail member and operative in response to movement of the tail member to move the upper and lower hooks in unison between their unlatched and latched positions;
• and
• a handle assembly including an escutcheon plate adapted to be mounted on the stile of the door, a handle mounted on the escutcheon plate, and a latch actuator device mounted on the escutcheon plate and including the tail member which is adapted to extend through an aperture in the stile for receipt by the actuator means.

A multi-point sliding door latch adapted to be fitted in a single opening in a lock face of a stile of a 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 unitary hollow housing adapted to fit in the stile opening;
• a pair of vertically spaced upper and lower hooks each mounted in the housing for 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 for latching coaction with the keeper structure;
• upper and lower actuators positioned in vertically spaced side-by-side relation in the housing intermediate the upper and lower hooks, mounted for rotation on the housing about vertically spaced axes, and each including a socket structure adapted to receive a tail member from the handle assembly and moveable about its respective axis in response to turning movement of the tail member;
• a gang link interconnecting the upper and lower actuators so that movement of one actuator generates corresponding movement of the other actuator;
• and
• means operative in response to movement of the actuators to move the upper and lower hooks in unison between their unlatched and latched positions.
