Abstract:
A door lock assembly includes a sleeve connected to a handle, a spindle tube inserted into the sleeve and having a spindle tab to control a latch, and a spindle driving plate disposed transversely within the spindle tube. A tail piece of a key plug attached to the handle engages a central aperture of the spindle driving plate. A radial tooth of the spindle driving plate extends radially into a slot of the spindle tube so as to rotate the spindle tube when the spindle driving plate is rotated by the tail piece. The door lock assembly has no transmitting element to transmit rotational movement from the sleeve to the spindle tube and does not permit retraction of the latch by rotating the handle.
