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 |

20130127184 | Latch Assembly for a Passageway Door Lock - A latch assembly includes a base having two sidewalls each having first and second guiding slots. A latch is pivotably connected to the base. A follower plate is movably received in the base and includes two sidewalls each having a restraining slot and en engaging notch. A safety plate is mounted between the sidewalls of the follower plate. A pin extends through the first guiding slots of the base, the restraining slots of the follower plate, and the safety plate. A positioning pin extends through the second guiding slots. A spring is attached between the positioning pin and the pin. When latch moves from a latching position to an unlatching position, the positioning pin moves along the second guiding slots of the base under action of the spring and engages with the engaging notches of the follower plate to retain the latch in the unlatching position. | 05-23-2013 |

20140265355 | Latch with an Automatic Locking Function for a Double Door - A latch assembly includes a latch having a body. A stop having a lower melting point is received in an engagement hole of the body. An ear is pivotable between a storage position in a transverse groove of the body and a blocking position partially extending out of the transverse groove. A pressing pin is slideably received in a longitudinal hole in the body. The ear is located in the storage position when the pressing pin is in a non-pressing position, allowing pivotable movement of the latch between a latching position and an unlatching position. When the latch is in the latching position and the ear is in the storage position, if the stop is melted by heat, the pressing pin is moved from the non-pressing position to the pressing position and pivots the ear to the blocking position, retaining the latch in the latching position. | 09-18-2014 |
20150252592 | Panic Exit Door Lock with an Indication of a Locking State - A panic exit door lock includes an outer operational device mounted to an outer side of a door, an inner operational device mounted to an inner door of the door, a lock mounted in the door, and a locking mechanism mounted between the inner and outer operational devices and the lock. The locking mechanism includes an outer cylinder mounted to the outer operational device and an inner cylinder mounted to the inner operational device. An indicator member is operably connected to the inner cylinder and a setting member. The setting member is connected to a transmission block. When a key is used to set a locking function of the inner or outer cylinder, the transmission block and the indicator member pivot jointly. A user can see whether the locking function is set by observing the position of the indicator member via a window of an inner cylinder seat. | 09-10-2015 |
