A release mechanism is actuated by the heat of a fire to electrically and mechanically disconnect electrical wiring from an electronic lock having a plastic housing. The electronic lock is mounted on a fire door and as it is heated by a fire on the opposite side of the fire door, mounts that hold the lock melt, releasing the electronic lock to drop away from the fire door and prevent ignition of the plastic housing. The release mechanism may use shape memory alloy wire to contract and disconnect a ribbon cable. Solder connectors may also be used to disconnect wires. Intumescent material that expands when heated is used to drive the lock mechanism away from the fire door and insulation is used to control the timing of melting.

A lock assembly includes an exterior lockset that includes an exterior operator handle. An interior lockset includes an interior operator assembly and a control electronics module. An outer spindle is operatively coupled to a latch assembly and is drivably coupled to the interior operator assembly. A locking mechanism is operatively coupled to a drive assembly, and includes a coupling mechanism and a locking spindle assembly. The coupling mechanism is configured to selectively couple the exterior operator handle to the outer spindle. The locking spindle assembly is configured to operate the coupling mechanism to transition from a locked condition to an unlocked condition by an actuation of the drive assembly. A lock position sensor is located in the interior lockset and is communicatively coupled to the control electronics module. The lock position sensor is configured to sense whether the coupling mechanism is in the locked condition or the unlocked condition.

A lock assembly includes an exterior operator assembly, an interior operator assembly, and a latch assembly. An outer spindle is operatively coupled to a latch assembly, is drivably coupled to the interior operator assembly, and has a longitudinal bore. A coupling mechanism is coupled to the outer spindle. A locking spindle assembly is rotatably received in the longitudinal bore, and is configured to selectively operate the coupling mechanism to couple the exterior operator assembly to the outer spindle upon actuation of a drive assembly. The locking spindle assembly has a fire compliant component made of a first material that melts during a fire to prevent operation of the latch assembly with the exterior operator assembly, and has a fire resistant component made of a second material and configured to block the longitudinal bore of the outer spindle to aid in preventing the spread of the fire through the door.

The invention relates to a lockable pin-type lock (1) for sliding doors, with a cylindrical housing (3) which can be fastened in the door leaf, and with a two-part locking pin (2) which can be displaced in the axial direction in the housing (3). In order to provide a lockable pin-type lock for sliding doors, which both permits a temperature-independent handling of the pin-type lock and also is simple to operate, it is proposed by the invention that the locking pin is formed from two parts, wherein the two parts of the locking pin can be displaced relative to each other in order to form an intermediate space.

A handle and lock which generally includes a base having an index pin, a stop positioned in a circular channel, and an aperture traversing the base. A shaft is rotatably engaged to the base. The shaft includes a nut-shaped platform and an arcuate positioning limiter disposed in the circular working channel. The nut shaped platform preferably includes a threaded bore to receive a fastener used to releasably attach a handle to the shaft. The handle generally includes a head portion having a nut shaped receiving area and an arcuate protruding positioning member for placement within the circular working channel. The nut shaped receiving area preferably covers the platform during rotation of the handle relative to the base. The head portion may also include a lock having a locking barrier connected to a locking cylinder. The locking barrier is also adapted for removable positioning within the circular working channel to prevent rotation between the rotational limiter and the stop thereby restricting rotation of the handle and shaft relative to the base. The shaft further includes a latch member designed to engage a latch receiver integral to a door frame used for latching of a door in a closed position.

A door lock with a reinforced fireproof effect includes a lock body mounted on a door and inner and outer operating units mounted to two sides of the door, respectively. The lock body includes inner and outer chassis made of ferrous material or stainless steel having a melting point higher than 1300° C. Inner and outer fixing members coupled with the inner and outer chassis are also made of ferrous material or stainless steel. Thus, these components of the door lock are less likely to melt during a fire, reducing the spreading speed of the fire.
