Rose locking mechanism

摘要

A rose locking mechanism developed with a hybrid lock architecture for a door designed to incorporate the functionality of a cylindrical lock architecture with the ease of installation of a tubular lock architecture is provided by the present invention. The hybrid lock architecture comprises 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 wherein rotational motion imparted on one of the handles is converted to linear motion within the chassis assembly in order to retract the bolt of the door latch assembly. The inside chassis assembly includes a rose locking mechanism positioned radially outward of said inside spindle.
