Abstract: A door locking system for child-safety door locking systems on an automobile door including a latch and a door lock mechanism. The door handle is incapable of unlatching the door when the locking mechanism locks the latch. The locking system includes a door panel having an opening for receiving the lock lever in a guard lock mode when moved to its locked position so that the lock lever is substantially recessed within the door panel. The lock lever and the door panel are constructed such that the lock lever cannot be accessed through the opening for manual movement back to its unlocked position. In the normal lock mode, the lock lever is not received within the opening in the door panel in the locked position so that it is accessible for manually moving the lock lever to the unlocked position. A key lock interconnects the lock lever and a lock rod for selectively actuating the locking mechanism.

Abstract: A theft detection mechanism is provided with a top ring which is depressed when a foreign object other than a key is inserted into a key inserting hole. A sensor is provided for detecting that the top ring is depressed. A top ring is inevitably pushed down when a foreign object other than a key is inserted into a key inserting hole to activate the sensor, thereby reliably detecting a stealing action. Moreover, the structure of a theft detection mechanism is made simple to reduce the cost thereof.

The slide plate has two opposing lugs for insertion into the grooves.

Abstract: A non-handed actuator for window locks, including a base securable to the window frame, a handle secured to the base for pivoting about a first axis through an angle of approximately X degrees, an oppositely extending drive link secured for pivoting with the handle, and a connecting link securable to the lock control member of a window lock. The connecting link is pivotable relative to the drive link and includes a spacing member and a connecting member. The connecting member is securable to the lock control member and pivotable relative to the spacing member between limit positions approximately 180 degrees apart. Tabs on the spacing member abut the connecting member when the connecting member is at either of the limit positions, with the connecting link being pivotable relative to the drive link through an angle of approximately 2X degrees, where X is between 140 and 180.

Abstract: A portable door lock assembly for locking a door in a partially open attitude has an elongated base member with a length greater than the width of a standard door frame. First and second hollow members are secured to opposite ends of the base member. A pair of central hollow members are secured to the base member between the first and second hollow members. An elongated cup mount member is provided. The cup mount member has a cup for receiving the bottom of a door pivotally secured to one end. Its other end has an outer diameter smaller than the inner diameter of the first, second and central hollow members so the first, second and central hollow members can telescopingly receive the cup mount member. The cup mount member is telescopingly secured in the particular hollow member depending on the type of entryway and which side of the door is hinged to the frame. At no time during use does the door lock have to be bolted, screwed or otherwise fastened to the wall, door, or frame.

Abstract: A motor-vehicle door latch has a housing, a latching fork pivotal on the housing, and a release pawl pivotal on the housing between a latched position retaining the fork in a latched position engaged around a bolt and securing a motor-vehicle door closed and an unlatched position in which the fork can release the bolt and allow the door to open. An inside door handle can move between a center rest position, an end open position, and an end lock position. A bowden cable has a sheath fixed to the housing and a core having a pair of ends one of which is attached to the handle for displacement of another end of the core jointly with the door handle. A locking lever can pivot between a locked position and an unlocked position.
