Problems solved by technology

Australian Patent Specification No. 662657 provides such a construction but has the problem that the installer has to assemble the operating parts of the deadbolt sleeve on site rather than simply connecting the same operating parts to the rest of the locking mechanism

Embodiment Construction

[0069] The drawing shows a multifunctional locking structure 100 for use on an access door of any building, particularly but not exclusively a domestic residential building. The multifunctional locking structure 100 includes an inner escutcheon subassembly 35 intended to be mounted on the inside of a door, an outer escutcheon subassembly 50 adapted to be mounted to the exterior surface of the door, and includes a strike plate 97 and a deadlock retaining box 98 The locking pin assembly 47.

[0070] figure 1 The components of the interior escutcheon subassembly 35 are shown, including the interior escutcheon plate 1 having upper and lower holes 36 to enable the plate 1 to be operably secured to a door (not shown). The plate 1 also comprises an opening 37 for mounting the button 2, an opening 38 for mounting the shaft insert 7 which mounts the lever handle 3 to the plate 1 so that the lever handle 33 can be moved relative to the plate 1 in use. Operatively pivots. Screw 19 sec...

Abstract

The specification discloses an improved multiple function door lock mechanism, comprising a latch bolt assembly (47) having a latch bolt (104), a fixed support housing (91, 92) mounting an operating mechanism for the latch bolt (104), the fixed support housing (91, 92) defining a cam track (136, 135, 137, 138), the operating mechanism for the latch bolt (104) including a crank arm (45), a cam track follower (133), and link connector means (130) connecting the cam track follower (133) to the latch bolt (104); the cam track (136, 135, 137, 138) defining at least three spaced positions being a first rearward position (138) indicative of a withdrawn position of the latch bolt (104), a second forward position (136) indicative of a dead locking position of the latch bolt (104) and a third intermediate position (135, 137) indicative of a latching position of the latch bolt (104). The improved multiple function door lock mechanism solves the problem that in the prior art, operation components of a latch sleeve have to be assembled on the scene, but can not be connected to other parts of a lock mechanism.

Description

technical field [0001] The present invention relates to an improved multifunctional door lock and improvements to parts of the multifunctional door lock. The door locking mechanism is intended for selectively latching, locking, or securely locking an access door of a property, particularly a main access door of a property, with deadbolt capability. Background technique [0002] A known dual function locking mechanism is described in Australian Patent Specification No. 662657. It is often desirable for the locking mechanism to fit into a conventionally shaped mounting cavity in the door that includes a transverse circular hole that traverses a hole extending from the edge of the door to accommodate a latch bolt sleeve. It is desirable that the lock mechanism be able to replace an existing locking or latch structure with an existing mounting chamber, or that the lock mechanism be installed to a new door with minimal installation effort. It would further be desirable that the...
