A locking member, at least a portion of which is in the guide channel, is operatively connected to the linkage assembly and is moveable from a locked position to an unlocked position, which correspond to those of the linkage assembly. A biasing mechanism is operatively connected to the locking member and biases the locking member to its locked position. A dogging member is moveably connected to the lock housing such that the dogging member can move from an undogged to a dogged position. | 05-07-2009 |
| 20090145179 | MORTISE LOCK - A mortise lock includes a case. A locking slide forms a bore to receive a spring and a steel ball to allow the locking slide to be slidable with respect to the lock case to abut against and/or disengage from a locking latch. The mortise lock is operated by turning an inside knob to drive a deadbolt and a latch lever and the locking slide is moved inward to engage a lever hub assembly thereby ensuring a locked condition. The mortise lock cannot be unlocked by operating an outside lever When an inside lever is depressed, the lever hub assembly is driven to cause the rocker arm to push away a hooking lever and a knob spindle assembly, thereby retracting the deadbolt and the latch bolt and simultaneously moving the locking slide outward to show an unlocked condition, whereby the mortise lock can be unlocked by operating the outside lever. | 06-11-2009 |
| 20090211317 | MORTISE DEADBOLT LOCK CAM ENGAGEMENT DEVICE - A stop arrangement for precluding disengagement of a mortise deadbolt lock element by a cam which is employed to extend and retract the element. The arrangement employs first and second stop arms angularly spaced from a cam, which are rotatable, along with the cam, and which engage the lock element to preclude over-rotation. | 08-27-2009 |
| 20090241612 | LOCKING DEVICE - The locking device contains an axle, a bolt, a positioning plate, and a cylinder. The axle is connected to a thumb-turn knob and, from a circumference of the axle, a lever is extended perpendicularly. The bolt has a vertical trough in a rear section. An end of the lever is embedded in the trough. The positioning plate has an elongated opening inside which the axle is embedded. The cylinder is positioned adjacent to and above the rear section of the bolt. The cylinder has a key hole in the center and an activation bar extended from a circumference of the cylinder. When the thumb-turn knob or a key in the key hole is turned, the positioning plate is moved towards an opposite direction. In turn, the lever of the axle pushes or pulls the bolt in the same directions as the key or the knob is turned. | 10-01-2009 |
| 20090266120 | Adjustable Driving Mechanism for Panic Door Lock - A door lock includes a bracket fixed to a door. A linking rod is slideably mounted to the bracket and includes a slot. A draw member includes a first end pivotably connected to the bracket and a second end operably connected to a retractor. The draw member further includes a guide slot. A pin slideably extends through the slot and the guide slot such that the movement of the linking rod causes pivotal movement of the draw member, which in turn, urges the retractor to move a latch bolt from an extended position to a retracted position. A follower is coupled to the pin to move therewith. An adjusting member is in threading connection with the follower and rotatable to move the follower and the pin relative to the linking rod to adjust a position of the second end of the draw member relative to the retractor. | 10-29-2009 |
| 20090282877 | Mortise Lock - A mortice lock is disclosed which has a lock casing which provides a first point of entrapment and a second point of entrapment, a latch bolt which can move between a latching position and an unlatching position, a handle for moving the latch bolt between the latching position and the un-latching position, a key cylinder, an operating assembly and a locking member. The operating assembly can move between a first position in which a deflectable portion of the operating assembly engages with the first point of entrapment and a second position in which the deflectable portion engages with the second point of entrapment. Only the key cylinder can move the operating assembly between the first position and the second position. The locking member (which is not a shoot bolt or part thereof) can move between a locking position in which a portion of the locking member engages with the latch bolt to prevent the latch bolt from moving into the un-latching position, and an unlocking position in which the latch bolt can move into the un-latching position. The locking member is operatively associated with the operating assembly such that moving the operating assembly into the first position moves the locking member into the unlocking position and moving the operating assembly into the second position moves the locking member into the locking position. | 11-19-2009 |
| 20100154490 | High Security Lock for Door - A high security locking system can be used in a conventional pivot door adapted for use with a latch and deadbolt lock combination.
