One of the stops has a ramp for camming engagement with the spring loaded cylinder bolt whereby in one lock plate orientation the bolt is locked out of the lock plate and in its reversed orientation the lock plate receives and entraps the bolt. The handle is particularly suited for use on delivery van type vehicles as it is fully compatible with existing lock cylinders that may be removed with spanner tools without having to disassemble the handle.

  • Patent number: 5841347
    Abstract: A one-touch doorlock device having a construction capable of being easily mounted at either a left or right side of a door by a simple manipulation, locking the door only by manipulating the doorknob without any additional manipulation, and outputting speech messages respectively corresponding to locked and unlocked states of the door by use of a microcomputer and a ROM as a speech memory stored with speech messages. The device thus provides easy and convenient doorlock mounting and provides convenience in use to the user. The doorlock device includes door locking mechanism for moving the locking bolt to its locked position. The door locking mechanism has a rotating member operatively connected to the doorknobs in such a manner that the rotating member rotates by a manipulation of the doorknobs, thereby moving the locking bolt between an extended position corresponding to the locked position and a retracted position.

  • Patent number: 5813255
    Abstract: The invention is a mortise lock constructed for very simple conversion between multiple functions and left and right hand openings. The lock can include or omit retraction of the latch bolt from either side with a key, permanent locking of either side's retractor, removal of the stopworks, simultaneous retraction of the latchbolt and deadbolt, or locking the retractor when the deadbolt is thrown. All of these conversions are accomplished without opening the case cover by the insertion or removal of screws or parts through holes in the cover or case, with the screws either stopping a part from moving or providing a catch upon which a part acts. The changeover between right and left handed openings is accomplished through the backplate with removal of only the armor plate, by removing, reversing, and reinstalling the latchbolt.

  • Patent number: 5722269
    Abstract: A locking device is used for doors of cabinets or cupboards and, more parularly, for doors of modular cupboard systems. In order to create an operationally reliable, inexpensive locking device which is suitable for narrow counterstops and which permits an installation independently of the fixing side, as well as an inexpensive conversion when the fixing side is changed, the locking device is given a bipartite construction with a handle positioned in the vicinity of a door plate and a bolt mechanism operable by a tumbler. The device has a first door plate area receiving the handle and a second door plate area. A locking movement, initiated by the handle, is subject to a deflection, preferably of approximately 90.degree., in the direction of a counterstop and a closed or open position of at least one locking element in a cabinet or cupboard-side receptacle is obtained.

    Abstract: A kit for converting a key-in-knob lockset to a lever handle operated lock employs the existing cylindrical lock and its associated latch bolt. The conversion apparatus employs a lever handle having a non-circular shank portion which is received in, and thus drives, a resiliently biased coupling device which is interpositioned between the handle and a rose housing affixed to the door. The existing cylindrical lock is supported within the lever handle shank portion by a dummy bible member in such a manner as to prevent forces resulting from operation of the lever handle from damaging the cylindrical lock.
