  • Patent number: 11156016
    Abstract: An anti-ligature handle and escutcheon mechanism mountable on a door for operating a lock for securing the door. The mechanism comprises a handle movable between open and closed positions, the handle having a smoothly curved outer surface to prevent the attachment of a ligature thereto and comprising a pivot at a first end for rotating the handle between the open and closed positions to operate the lock. An escutcheon fixed relative to a backing plate is oriented for mounting parallel to the door when the mechanism is mounted on an outer surface of the door, wherein the escutcheon surrounds the handle and defines a recessed area within which the handle pivots. The handle further has a second end including a guide which is trapped beneath and slides along an arcuate edge of the recessed area of the escutcheon to maintain flush contact between a mating surface of the handle and the backing plate to prevent ligatures from being inserted therebetween as the handle rotates to operate the lock.

  • Patent number: 10669747
    Abstract: A swing bolt lock includes a swing post, a cam dog, and an electric device cooperative with a lock bolt. The electric device includes a motor, a slider connected to a rotating shaft of the motor. Without an unlock authorization, the slider is situated in the space at an end of a sliding slot and abutted against the cam dog to prevent the cam dog from moving towards the space at the end of the sliding slot, so as to prevent the lock bolt from entering into the lock housing. With an unlock authorization, the slider is driven by the motor and released from the abutment of the cam dog, and the cam dog is driven by the lock bolt and swing post to enter into the space at the end of the sliding slot so as to release the locking of the lock bolt from turning into the lock housing.

  • Patent number: 4989908
    Abstract: A latching device for sliding doors/windows which has a smooth, modern appearance and which enables a person to free himself. The device is used in combination with a push-bolt or bayonet style door lock mounted on a sliding door/window. Means for latching the bolt of the lock to the frame of the door/window includes a slotted, slideable frame member. The slideable frame member fits unobtrusively against the frame with no protruding parts. The bolt on the lock can be extended into a notch which is formed in the frame of the door/window and which includes a side opening. When the door/window is locked, the slideable frame member blocks this side opening, so that the bolt cannot escape. Alternately, by bringing a cutout in the frame member into alignment with the side opening, the frame member can be positioned so as not to block the side opening, thereby forming an opening through the bolt can move sideways.

  • Patent number: 4563885
    Abstract: The present invention provides a door lock assembly and method which will provide security for building owners and dwellers and will result in a reduction of property damage and loss by burglars. The door lock assembly includes a tumbler type cylinder which can be rotated by a key from the outside to lock a door or other closure to which it is fitted to a first position whereupon the handle inside the door cannot be used to unlatch the lock from the inside. Also, the door can be locked and thereafter the cylinder can be rotated by turning the key in the reverse direction whereupon the door remains locked but upon withdrawing the key the door can be opened from the inside with the handle. Thus, after locking, the key can be withdrawn in either of two cylindrical positions depending on whether the user wants the door to be able to be opened from the inside by use of the handle.
