Push button door locking mechanism

Abstract

A push button door locking mechanism developed for a hybrid lock and architecture designed to incorporate the functionality of a cylindrical lock architecture with the ease of installation of a tubular lock architecture. The push button door locking mechanism comprises a push button mounted on a push button carrier housed within an inside spindle of a door lock assembly. A main retractor is co-rotatingly attached to the inside spindle. A locking catch assembly having a head portion on a first end thereof wherein the head portion matingly attaches to the push button carrier, and a locking catch engageable against the retractor component in a manner preventing axial movement of the locking catch assembly. A push button spring biases the locking catch assembly in an unlocked position. The present invention also relates to a lock assembly for a door comprising a chassis assembly mounted in a bore of the door including an inside chassis assembly and an outside chassis assembly. The inside chassis assembly and the outside chassis assembly are telescopically engaged to accommodate different door widths. A door latch assembly is operably connected to the chassis assembly for retraction and extension of a bolt. A handle is mounted on a spindle on either side of the chassis assembly. Each side of the chassis assembly has a fixed spindle end to door length regardless of variations in the door thickness. The lock assembly further comprises a push button locking mechanism along a central rotational axis of the chassis assembly.
