US Patent 6945572 Sliding door latch assembly

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.
