摘要： A door latch set consists of two knob-door plate sub-assemblies and a latch assembly, all of which can be assembled together and retained within the door without the need for any supplementary non-integral fastening or connecting elements. Each knob is rotatably retained within its door plate by a snap interlock, and the two door plates retain each other within the door by opposed toothed faces on resilient fingers. The latch is a flexible strap which winds around a knob spindle to retract upon knob rotation, and the latch assembly is retained within the door by interlocking means on one of the door plates.
