Patent

CA 2422445

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.

L'invention concerne un mécanisme de serrure rapidement installé comprenant une connexion mécanique semi-permanente installée entre un ensemble verrou intérieur et un ensemble verrou extérieur. Ledit ensemble verrou extérieur comprend deux fixations filetées traversant un alésage préformé dans une porte, l'ensemble verrou intérieur comprenant une garniture de rosette configurée de façon à coopérer par rotation avec lesdites fixations afin de connecter les ensembles verrous intérieur et extérieur. La garniture de rosette comprend deux parties profilées dressées dotées d'ouvertures destinées à recevoir les fixations, et des parties inclinées destinées à guider ces fixations dans lesdites ouvertures. L'ensemble verrou intérieur comprend, en outre, un insert de bouton et un guide de bouton du type serrure camarde. Ledit insert de bouton est disposé dans le bouton, et le guide de bouton du type serrure camarde est disposé amovible dans l'insert de bouton. Le bouton du type serrure camarde est disposé dans le guide de bouton du type serrure camarde, et est aligné avec un élément fonctionnel s'étendant depuis un cylindre de verrou placé dans l'ensemble verrou extérieur. Du fait que l'ensemble bouton intérieur est connecté à l'ensemble bouton extérieur, le guide de bouton du type serrure camarde sort de l'insert de bouton, ce qui libère le bouton du type serrure camarde pour rotation conjointe de l'élément fonctionnel et du cylindre de verrou.
