Abstract (en)
[origin: GB2498340A] A latch operating device comprising a worm bushing 1 (button) confined for axial sliding having an internal helical groove 13 and worm shaft 2 confined for rotary movement having a helical thread 6. Linear movement of bushing 1 is converted into rotary movement of shaft and a spring 7 biases the bushing to return to a neutral position. Shaft 2 may have a recess 15 for inserting spindle of a latch mechanism. Preferably (see fig.3, 4) a push button (8) with teeth (19) cooperates with rotor (9) having teeth (25) and splines (18) to sequentially index the position of the bushing to hold the latch in a retracted position and an extended position. The push button latch can be used on toilet doors where hygiene is of a concern.
