This disclosure provides systems and methods for lockout-tagout procedures and systems supporting the same, including, without limitation, locking devices that can store and be locked simultaneously by multiple keyholders. In various embodiments, a single user can add multiple keyholders to a locking device. The user may not be able to remove anyone as a keyholder except himself or herself. Thus, the locking device may remain in a locked state until each of the added keyholders applies their digital key, password, PIN, and/or other personal identifying information to unlock the locking device by removing themselves as a keyholder.

A door locking system for opening and closing a door lock in a door. The door locking system includes a first door handle unit with a first door handle and a second door handle unit with a second door handle. The first door handle and the second door handle are pivotable about a common pivot axis. The door locking system comprises a coupling device with an axially aligned polygonal pin which has two pin pieces. The respective pin piece is connected to the respective door handle in a pivotably fixed manner.

A lockcase is mountable upon a surface of a doorway jamb which is selectively closable by a barn door. The lockcase includes a bolt which translates or otherwise moves relative to the lockcase to selectively engage a strike in the barn door. The bolt is actuated by movement of a handle on a lever mounted to the lockcase. In one embodiment, the lever rotates to cause a shuttle to translate and with the bolt mounted to the shuttle. Detents on the shuttle tend to keep the bolt in either a retracted or a deployed position relative to the lockcase and the strike.

In a lid opening and closing device for a vehicle, a restriction member restricting movement of a rod and an electric motor driving the restriction member are housed in a case fixed to a vehicle body outer plate. An emergency operation member extends movably through a vehicle body inner plate while enabling the restriction member to move when the electric motor malfunctions, the emergency operation member being resiliently urged toward an initial position side at least when being operated. A grommet for preventing intrusion of water is provided between the emergency operation member and the vehicle body inner plate. The grommet includes a grommet main portion liquid-tightly mounted on the vehicle body inner plate while having the emergency operation member movably inserted therethrough, and an elastic portion integrally connected to the grommet main portion while enabling the emergency operation member to be resiliently urged toward the initial position side.

An interconnection assembly includes a chassis, and cam plates that are rotatably coupled to the chassis to pivot about a plurality of rotational axises. An upper cam plate is operatively coupled to a deadbolt. The upper cam plate has a cam surface. A lower cam plate is rotatably coupled to the chassis to pivot about a second rotational axis. The lower cam plate is operatively coupled to an interior latch bolt handle. The lower cam plate has a cam slot. A linkage bar is rotatably coupled to the chassis to pivot about a pivot axis. The linkage bar has a first linkage portion having a first cam follower configured to operatively engage the cam surface of the upper cam plate and has a second linkage portion having a second cam follower operatively received in the cam slot of the lower cam plate.

An escape release mechanism that serves as a supplementary means for unlocking a solenoid-driven locking switch. The escape release mechanism comprises a knobbed escape release switch that can be pressed by an operator from inside a protected industrial area to override the solenoid-driven lock. In response to a single-direction linear movement of the escape release key, a pin extends from the escape release mechanism in a direction orthogonal to the escape release key's linear movement. This forward movement causes the pin to displace the locking bolt of the locking switch. As the single-direction linear movement of the escape release key continues, the pin retracts from the locking switch out of the path of the locking tongue, allowing the tongue to be removed. In this way, the pin is both extended and retracted in response to a single-direction linear action by the operator.

Disclosed is a closure for a door of a shipping container. The closure includes a housing, an outside handle pivotally mounted relative to the housing, an inside handle pivotally mounted relative to the housing, and a catch connected to the inside handle. The closure is configured so that movement of the inside handle between a first position and a second position causes corresponding movement of the catch. A locking mechanism can releasably fix the inside handle relative to the outside handle, such that when in a locked position rotation of the outside handle causes corresponding rotation of the inside handle and when in an unlocked position the inside handle can be rotated independently of the outside handle.

A modular surface mounted electric strike system is provided. The system comprises a universal base plate having first and second sides, each having first and second mounting points. Each electric strike module includes a header, a keeper assembly, and an actuator assembly configured for moving between a keeper blocking mode and a second mode. When the first and second latches are separated a first distance, the first and second electric strike modules are attached to the first mounting locations on the respective first and second sides of the base plate. When the first and second latches are separated a second distance, the first electric strike module is attached to the second mounting location on either the first or second sides of the base plate, and the second electric strike module is attached to the second mounting location on the other of the first or second side of the base plate.

A surface mounted electric strike for selectively retaining a door latch of a door is provided. The electric strike comprises a housing mounted to a surface of the door frame, wherein the housing defines a cavity configured for receiving the door latch. A keeper is mounted within the housing and movable between a latched position and an unlatched position. The keeper includes a keeper body portion and an extended lobe portion having a terminal end. An actuating assembly is configured for moving between a first mode and a second mode, wherein when the actuating assembly is in the first mode the keeper is prevented from moving toward the unlatched position, and wherein when the actuating assembly is in the second mode the keeper is permitted to move toward the unlatched position.

A privacy lock assembly and method of operation are provided. The lock assembly has a push button offset from the central axis of the lock assembly for locking and unlocking the assembly. The lock assembly includes compression springs to maintain integrated handles in predetermined orientations when the handles are not subject to a load.
