A locking assembly for a non-pivotable door is provided. The locking assembly comprises a spacer plate defining a spacer plate bolt void and a strike plate defining a strike plate bolt void. The spacer plate and strike plate are to be coupled to one another and further fixedly coupled to the non-pivotable door, such that the spacer plate bolt void and the strike plate bolt void are aligned. The locking assembly further comprises a locking mechanism and a housing, which is configured to receive and contain the locking mechanism. The locking mechanism comprises a latch bolt that is moveable between a retracted position within the housing and a deployed position. In the deployed position, the latch bolt extends outwardly from the housing and into each of the spacer plate bolt void and the strike plate bolt void, thereby locking the non-pivotable door to the housing.

Certain aspects of the technology disclosed herein include an apparatus and method for storing energy in a electromechanical lock. The electromechanical lock can include a main housing and a deadbolt. The main housing can be configured to extend a deadbolt along a path to lock and/or unlock a door. The deadbolt can have a hollow inner region configured to receive an energy storage device. The energy storage device within the deadbolt can be electrically connected to the main housing. The energy storage device can be used to power an actuator and/or accelerometer in the main housing.

In an embodiment, the present application provides a lock for a door. The door has a front side and an opposing, back side which define a lock installation hole therethrough. The lock comprises: a front panel assembly, disposed on the front side; a rear panel assembly, disposed on the back side; a lock body, disposed within the lock installation hole; and at least one connector. The front panel assembly and the rear panel assembly are fixedly connected to the front side and back side, respectively, by the at least one connector, at least a portion of the front panel assembly and/or at least a portion of the rear panel assembly comprises a high-temperature resistant material, and when in an installed state, the at least a portion of the front panel assembly and/or the at least a portion of the rear panel assembly is configured to cover the lock installation hole. The lock provided by the present application has fireproof capability and is simple and convenient to install.

A lockset apparatus according to certain embodiments includes one or more features that facilitate the assembly and/or installation of the lockset. By way of example, certain embodiments relate to an outside trim assembly including one or more features that facilitate installation of a spring cage, a lock module, a lock cylinder, a light guide, a battery tamper monitor, and/or a request to exit sensor. In certain forms, an outside trim assembly and/or an inside trim assembly may be utilized across multiple formats of access control device, such as the mortise format, the tubular format, and/or the exit format.

A fastener operating structure includes a holding base and a fastening-connecting unit. The holding base is disposed at a first object. The fastening-connecting unit is movably disposed at the holding base. The fastening-connecting unit is fastened to a second object. Consequently, the holding base is disposed at the first object, and the fastening-connecting unit is coupled to or removed from the second object, so as to couple together and separate the first and second objects repeatedly and quickly.

A handle assembly includes a lock cylinder of a selected one of a first standard or a different second standard. A tail piece extends from the lock cylinder. The handle assembly also includes a vertical tubular member, a horizontal tubular member and a transition plate. The transition plate is disposed within the vertical tubular member and is moveable between a first position and a different second position. The transition plate accommodates installation of the lock cylinder of the first standard when in the first position and installation of the lock cylinder of the second standard when in the second position. A mechanical linkage is coupled to the tail piece and effects movement of a locking bolt in response to turning of a key in the lock cylinder.

A door plate has a main body with a front side, a rear side, a top side, a bottom side, a first adjacent side, and a second adjacent side. The main body includes a handle aperture and fastener apertures. The handle aperture is configured to receive a door handle of the door. The handle aperture is formed through the main body from the front side to the rear side of the main body. Each of the plurality of fasteners is formed through the main body from the front side to the rear side. The main body has a depth defined by a maximum distance between the front side and the rear side of the main body at the second adjacent side of the main body. The depth of the main body militates against a prying of the door with a crowbar where the main body is installed on the door.

An indicator assembly according to certain embodiments generally includes a mounting bracket, a follower, a transmission ring, and an indicator plate. The follower is rotatably mounted to the mounting bracket, and is configured to receive a tailpiece of an input device. The transmission ring is rotatably mounted to the mounting bracket, and is engaged with the follower. The indicator plate is slidably mounted to the mounting bracket for movement between a first indicator plate position and a second indicator plate position to selectively place a first indicium of the indicator plate within a reference area. The transmission ring is operably connected with the indicator plate such that movement of the transmission ring between a first transmission ring position and a second transmission ring position drives the indicator plate between the first indicator plate position and the second indicator plate position.
