ABSTRACT:
An improved door handle and lock assembly is provided for use with sliding glass patio doors of the type used in residential dwellings and the like. The handle and lock assembly comprises inside and outside escutcheons for mounting onto the vertical stile at one side edge of a sliding door and carrying a respective pair of handles for use in manually sliding the door between open and closed positions. A lock mechanism mounted into the stile is operated by a keyed lock cylinder unit mounted on the outside escutcheon and by a manually pivoted latch lever mounted on the inside escutcheon. The handles and latch lever are adapted for reversible mounting onto their associated escutcheons to permit reconfiguration of the assembly for mounting onto the stile at the left or right side edge of the door. In addition, the outside escutcheon is supported on the door stile by an inside bracket plate which permits partial mounting of the assembly onto the door and to permit operation of the lock mechanism without the inside escutcheon during a construction phase, with the inside escutcheon being subsequently mounted over and concealing the bracket plate.
