Abstract: A slide component developed for a hybrid lock architecture 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 slide component comprises a U-shaped body portion and a plurality of independent retractors. At least one pair of slots are positioned near an open end of said U-shaped body for attachment of a drawbar of a door latch assembly of the hybrid lock assembly. The hybrid lock assembly comprises a chassis assembly mounted in a bore of said door. A door latch assembly is operably connected to the slide component housed in the chassis assembly for retraction and extension of a bolt.

Abstract: A door lock having a clutching mechanism for selectively engaging and disengaging the outer handle of the lock from a key spindle having latch scoops for operably engaging a latch slide. The key spindle contains a cam mechanism for moving a dogging arm from a clutched position where the outer handle through a keyed outer spindle is keyed to the key spindle to an unclutched position where the dogging arm is positioned within a circumferentially extending slot which permits about 60° rotation of the outer handle relative to the key spindle without movement of the key spindle. Hard stops are provided on an outer driver and outer hub which limit movement of the outer handle to less than the rotation permitted by the clutching mechanism.

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.

Abstract: A door latch operating assembly is capable of rotating a door latch arm between a first locked position for locking a door in a closed position and a second unlocked position for unlocking the door. The latch operating assembly includes a lock platform and a handle having a gripper portion which is grasped by a person's hand for rotating the handle, and a shaft portion attached to the gripper portion and extending therefrom through an opening in the lock platform. A driver cam has a housing which receives the shaft portion of the handle, and at least one wing member extending laterally outwardly from one side of the housing. The wing member has an upwardly facing engaging surface for engaging a link which is linearly movable with respect to the lock platform. The link has a bottom edge portion with a downwardly facing engaging surface which bears against the upwardly facing engaging surface of the wing member of the driver cam, and a top edge portion with an upwardly facing engaging surface.

Abstract: A door handle mounting assembly capable of being mounted on a door includes a lock platform having an opening formed therein and a handle mounted on the lock platform without the need of mechanical fasteners, staking or welding. More specifically, the handle has a gripper portion which is grasped by a person's hand for turning the handle, and a shaft portion which is attached at one of its ends to the gripper portion. The shaft portion extends through the opening of the lock platform and has a circumferential groove formed therein. A retaining collar having an annular wall is positioned to engage the lock platform, the collar having an inwardly projecting annular ring connected to the annular wall. The assembly also includes a driver cam having a housing with a hollow boss extending through the opening of the lock platform along a longitudinal axis.
