Patent number: 4724690Abstract: A security bolt including a housing and a bolt rod slidably mounted on that housing for relative movement between operative and inoperative positions. The rod is cylindrical and has a section of reduced diameter between its ends so as to form two opposed shoulders. Key operated locking mechanism, having a rotatable barrel, is attached to the housing and a detent member is rotatably mounted on an end portion of that barrel. The detent member is rotatable to a position at which it engages one of the rod shoulders and thereby prevents movement of the rod out of the operative position. Rotation of the detent member is caused by rotation of the barrel, but a lost motion connection enables the barrel to rotate to a limited extent in either direction without causing corresponding rotation of the detent member. The locking mechanism can be removed from the housing through a rear side and releasable securing means controls that removal.Type: GrantFiled: August 22, 1986Date of Patent: February 16, 1988Assignee: Ogden Industries Pty.

Patent number: 4135376Abstract: A patio door or sliding window security bar which is of the type that is normally stored parallel to a frame member of the opening and movable to a horizontal position braced against the sliding panel frame or jamb so that the sliding panel cannot be moved to give access through the opening. A bolt is fully contained within the hollow bar end and capable of being reciprocated through the medium of a barrel or cylinder that is installed into the lateral wall of the bar to enable the bolt to be moved into a socket formed in the sliding panel frame to lock the bar against being swung upward or downward. A locking arrangement including a keyway enables the bar to be locked in horizontal position by means of a removable key to prevent unauthorized opening of the patio door even from the interior of the building having the opening.Type: GrantFiled: July 11, 1977Date of Patent: January 23, 1979Assignee: Charles Bar-Lok Corp.Inventors: Arthur A.

Patent number: 4068506Abstract: A hidden or concealed lock for sliding windows, door panels and the like, employing a concealed hollow tubular locking sleeve that is positioned entirely inside of an aligned opening passing through the interior frame of one of said windows and into the frame of the other window. The locking sleeve is manipulated into and out of locking position by a small rod shaped key member that is coaxially insertable into the locking sleeve from outside the window after passing through the small opening in the window frame. Both the locking and key members and openings are made small and unobstrusive; and are located for concealment in differing locations. These features prevent an unauthorized user from either locating the lock, determining its mode of operation; or unlocking the windows or panels without access to the special key.Type: GrantFiled: November 5, 1976Date of Patent: January 17, 1978Inventor: Robert A.

Patent number: 4050272Abstract: A lock assembly having special utility for locking sliding doors and the like is disclosed. The lock assembly comprises a cylinder lock having a rotor case and a rotatable rotor disposed therein. The rotor has pin members configured such that upon insertion of an associated key into the rotor, the pin members retract and the rotor is rendered selectively rotatable in the rotor case. A movable runner is coupled to the rotor and a hook member is coupled to the runner such that when the runner is moved from the unlocked position to the locked position, the hook moves into a "deadlock" zone. A driver member is also connected to the runner to aid it in moving from its locked position to the unlocked position and vice versa.Type: GrantFiled: May 12, 1976Date of Patent: September 27, 1977Assignee: K.K.

Patent number: 3956911Abstract: A lock for the runners, particularly for runners of sliding glass doors on a display case which comprises a box-like housing including at the front sliding glass doors. A locking bolt is displaceable in axial direction and is adapted to enter into a bolt opening of another overlapping, opposing runner. A locking cylinder is operatively connected with the locking bolt, and a device is arranged for moving the locking bolt from its advanced bolt engagement position into its open position independently of the locking cylinder.The present invention relates to a lock for runners, particularly those of sliding glass doors or showcase windows, having a locking bolt on a first runner which can be displaced in axial direction and which engages in a bolt opening of another overlapping mating runner and with which a lock cylinder is coordinated.The one known lock for runners, a lock cylinder and a locking bolt are arranged parallel to one another in a common housing. The latter is fastened to one runner.Type: GrantFiled: September 14, 1973Date of Patent: May 18, 1976Assignee: Firma Josef Voss KG.Inventor: Gerard Corboud
