ABSTRACT:
A door holding latch, primarily for holding a door in open position, using a telescopic strut with an enclosed cam latch which engages when the strut is collapsed. The cam latch is incorporated in an end of a torsionally resilient rod which slides in a sleeve and engages a latch pin extending across the sleeve, the cam being angularly offset so that the rod must twist as the cam engages the pin. The torsion applied to the rod locks the cam in place, the latch being released by a pull on the door sufficient to overcome the frictional grip of the latch.
