Embodiment Construction

[0015] With reference to the accompanying drawings, the present invention relates to a complete door locking mechanism which can be easily secured to door assemblies having different thicknesses. The set of door locks has several design features that allow for easy alignment of the set of door locks and quick assembly and installation.

[0016] Fig. 1 has shown a preferred embodiment of a complete door lock mechanism 10, and this complete door lock mechanism 10 comprises an outer knob assembly 12, an inner knob assembly 14 and a deadbolt assembly 15 (see figure 2 ). The outer knob assembly 12 includes: a semicircular part 16; a full circular part 18 (see Figure 8 ); a torsion spring assembly 38 (see Figure 8 ); a pair of rods 20. The rod 20 is adapted to receive a bolt 22 for providing a position in which the inner knob assembly 14 is releasably secured. The inner knob assembly 14 includes: a blade 24; a knob 26; a blade spring 30; a knob insert 32; a blade guide 34; a r...

Abstract

The present invention provides a quick install lockset mechanism having a semi-permanent mechanical connection between an interior lock assembly and an exterior lock assembly. The exterior lock assembly includes a pair of threaded fasteners extending through a preformed hole in a door, and the interior lock assembly includes a rose liner configured to rotatably engage the fasteners to connect the interior and exterior lock assemblies. The interior lock assembly rose liner includes a pair of raised contoured portions having openings for receiving the fasteners and ramps for guiding the fasteners to the openings. In addition, the interior lock assembly includes a knob insert and a turnpiece guide. The knob insert is disposed in the knob and the turnpiece guide is removably disposed in the knob insert. A turnpiece is disposed in the turnpiece guide and is thereby aligned with an operating member extending from a lock cylinder in the exterior lock assembly. As the interior knob assembly is connected to the exterior knob assembly, the turnpiece guide is pushed out of the knob insert, thereby freeing the turnpiece for co-rotation with the lock cylinder-operating member.

Description

technical field [0001] The present invention relates generally to a door lock mechanism for a door assembly, and more particularly to a semi-permanent mechanism for establishing a semi-permanent connection between an inner knob assembly and an outer knob assembly of a door lock mechanism. Devices and methods used for mechanical joining. Background technique [0002] In conventional door lock assemblies, the interconnection between the inner and outer seat components is made by threaded fasteners. The outer housing assembly typically includes two internally threaded bosses that align with two features formed on the inner housing assembly. A standard machined bolt is inserted into the inner housing assembly and the bolt is aligned and threadedly engaged with a threaded boss formed on the outer housing assembly. The bolts are tightened to bring the inner and outer seats closer to each other, thus constraining the door between the inner and outer seats. [0003] This common m...
