Flush pull

Combined door pull and latch guard

A door lock arrangement comprising a frame, a door handle, a slidable deadbolt arrangement, a depressable trigger member for releasing the slidable deadbolt, a deadbolt driver for sliding the deadbolt to its extended position when triggered, and a bidirectional retraction assembly, whereby rotation of the door handle in either direction moves the deadbolt from the extended position to the retracted position. In another aspect of the invention, there is provided a door lock arrangement comprising a frame, a door handle, a slidable deadbolt arrangement, a depressable trigger member for releasing the slidable deadbolt, a deadbolt driver for sliding the deadbolt to its extended position when triggered, and a retraction assembly comprising a retraction arm having a nose portion which interferes with a part of the deadbolt when the deadbolt attempts to return to its retracted position, thereby reliably and securely blocking retraction of the deadbolt and frustrating any tampering attempt to move the deadbolt back into the fixture with a tool pressing against the distal end of the deadbolt. The door handle releases the blocking effect of the retraction arm and, simultaneously, draws the deadbolt rearwardly into its retracted position.
