摘要: The present disclosure provides a fire door lock mechanism. A handlebar is coupled to one end of an actuator whose the other end is connected with a push rod. A lock bolt is rotatably mounted in a lock cover mount which accommodates a glide mount used to drive the push rod to move horizontally. When the actuator receives a depression force from the handlebar, the actuator is driven to rotate and induces the push rod to move horizontally. By the movement from the push rod, the lock bolt is driven to rotate to engage or disengage the lock mechanism. A partition and a fire piece are coupled to the glide mount. The fire piece melts at a high temperature during a fire, making the partition moved by a force from an elastic member connected thereto and cause the lock bolt to be engaged with the partition and maintained in a locked state.

摘要: A push pad exit device comprising a horizontal push bar actuator mechanically linked to a vertical door handle assembly for use on the interior side of entrance doors where a means of emergency egress is desired, is presented. The operating mechanisms of the push bar actuator and vertical door handle assembly are concealed presenting a smooth uncluttered appearance. The push pad exit device further including an improved roller latch bolt. The improved roller latch bolt allows for a roller to make contact with a ramp surface of a corresponding strike plate on a sweep side of the plate and allows for the roller support to make contact with the strike plate on a latch side of the plate.

摘要: A rotation converter according to certain embodiments generally includes a case, an input member, a shuttle, and an output member. The input member is rotatably mounted to the case, and is rotatable from an input member home position in each of a first rotational direction and a second rotational direction. The shuttle is movably mounted in the case, and is engaged with the input member such that rotation of the input member from the input member home position in each of the first rotational direction and the second rotational direction drives the shuttle from a shuttle home position to a shuttle actuated position. The output member is rotatably mounted to the case and engaged with the shuttle such that the output member rotates in an output member rotational direction in response to movement of the shuttle from the shuttle home position to the shuttle actuated position.

摘要: A knob-less horizontal-shift fire door lock includes a base including a longitudinal bar, an unlocked-state positioning member arranged in the longitudinal bar and having a positioning section; a latch pivoted to the base and having a free end elastically biased outside the base to engage a keeper on a door jamb; a push board pivoted in the base; and a handle bar slidably mounted on the longitudinal bar. The handle bar is biased by an elastic element to protrude outwards and moving a guide pin to slide in a guide groove of the positioning section. The handle bar is depressible toward the longitudinal bar to move the push board to drive the latch to retract into the base to achieve an unlocked state. The handle bar is further shiftable horizontally to cause the guide pin to slide into a horizontal groove of the positioning section for being secured in position.

摘要: A door latch system comprises an interchangeable latch assembly for securing a door to a door frame. The interchangeable latch assembly comprises a head and a latch mounted to the head. The latch is moveable between latched and unlatched positions. A driven member is operatively connected to the latch, the driven member moveable to latch or unlatch the latch. The door latch system further comprises a universal actuating assembly removably couple-able to the interchangeable latch assembly. The universal actuating assembly comprises a mounting bracket and a driving member releasably coupled to the driven member. Actuation of the universal actuating assembly translates the driving member and the driven member, moving the latch to the unlatched position. A first interchangeable latch assembly may be swapped with a second interchangeable latch assembly without requiring modification of the universal actuating assembly.

摘要: A reinforcing assembly may be configured for use in conjunction with a door latch mechanism. The reinforcing assembly is configured to reside within a recess or mortise defined within a body of the door. A body of said door latch mechanism is configured to be received, at least in part, within said reinforcing assembly. The reinforcing assembly includes a body having a back plate and one or more walls thereby defining a latch receiving cavity. At least one fastener is configured to secure the reinforcing assembly to the body of the door. The at least one fastener may be oriented substantially normal to the transverse plane of the door when securing the reinforcing assembly within the body of the door.

摘要: A latch assembly is configured to be operable within a door latch system where the door latch system releasably secures a door in a door frame. The latch assembly comprises a housing and a latch pivotally mounted in the housing. The latch includes a lock-out feature. A translating bar is connected to the latch and is moveable by at least one actuation mechanism to selectively pivot the latch from an extended position wherein the door is secured in the door frame to a retracted position wherein the door is released from the door frame. A deadlatch is coupled to the latch. A bracket assembly is coupled to the latch and deadlatch, wherein the bracket assembly engages the lock-out feature when the deadlatch is in an engaged position to prevent pivoting of the latch.

摘要: 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.
