Abstract
A lock platform for a door includes a face plate lying in a vertical plane parallel to the plane of the door and an outer peripheral edge margin which extends from the outer periphery of the face plate generally perpendicularly away from the face plate and towards the door when mounting the lock platform on the door. The edge margin engages the door in such a manner that the face plate is spaced from the door thereby creating a space between the face plate and the door for accommodating components of a handle and lock assembly. The lock platform further includes an outwardly facing hollow boss located on the face plate and spaced from the hole of the door when mounting the lock platform thereon. The boss defines a first opening for receiving a handle of the handle and lock assembly or the like therein. The lock platform also includes a second opening for receiving a key cylinder, thumb turn member or the like therein. The second opening extends generally co-axial with respect to the hole of the door wherein when a key cylinder is mounted on the lock platform within the opening, the key cylinder extends into the hole of the door. Screw fasteners mount the face plate of the lock platform to a face plate of a second lock platform of similar construction positioned oppositely with respect to the lock platform on the other side of the door.
