Abstract
A sliding door has a latch assembly and a vertically disposed pull handle that would normally interfere with convenient operation of the latch lever. A rotatable latch lever is located beyond the handle and a rotatable latch is located opposite the handle. A 4-bar coupling extends between the lever and the latch so that the latch is conveniently rotatable from beyond the pull handle for engaging a cooperating keeper.
Claims16
A sliding door latch assembly comprising:
- an escutcheon plate comprising a central area and a terminal area;
- a handle secured to the central area of the escutcheon plate;
- a rotary actuator rotatably mounted within the central area of the escutcheon plate, the actuator adapted to actuate a latch hook when installed on a sliding door sash having a latch hook therein;
- a lever rotatably mounted to the terminal area of the escutcheon plate;
- and
- at least one link connecting the lever to the rotary actuator, the at least one link comprising a rotatable lever plate and at least two bars, each bar attached at a first end to the rotatable lever plate and attached at a second end to the rotary actuator, wherein rotation of the lever causes corresponding rotation of the rotary actuator.

A sliding door latch assembly comprising:
- an escutcheon plate;
- a lever rotatably mounted to the escutcheon plate;
- a latch hook distal from the lever;
- a transmission comprising at least two bars, each bar comprising a first end and a second end, wherein the at least two bars are substantially parallel along at least a portion thereof, the transmission located at least partially within the escutcheon plate for transmitting a rotary movement of the lever to the latch hook;
- a rotatable lever plate secured to the lever;
- a rotatable actuator plate adapted to actuate the latch hook, wherein the first ends of the bars are connected to the lever plate and wherein the second ends of the bars are connected to the actuator plate;
- and
- a handle secured to the escutcheon plate in at least one connection point, wherein the connection point is between the lever and the latch hook.
