A system to barricade a door from forced entry is disclosed. The system includes an anchor insertable by a user into a receptacle mounted into a floor on the inside on the door, and a lock affixable to the door. The anchor includes an upper portion designed to connect with the lock, and a lower portion that preferably fits within the receptacle. The lock includes a stop designed to contact the outside surface of the door, and a key plate on the inside of the door. When the anchor is vertically inserted into the receptacle, the upper portion of the anchor engages the key plate of the lock affixed to the door, which in conjunction with the stop prevents the door from swinging outwards. The anchor can be removed from the receptacle when the user doesn't desire to barricade the door.

A length adjustable door lock includes a latch assembly, a lock core connected with the latch assembly, a lock bolt connected with the lock core, and a housing sleeved on the lock bolt. The latch assembly and the lock core respectively have an embedding opening and slot having matchable shape, wherein a buckling portion is formed and provided on the lock bolt coordinately, wherein the buckling portion is adapted for being assembled in the slot of the lock core through the embedding opening, which is easy for the assembling.

The present invention discloses an intelligent lock device with a photoelectric switch-controlled motor, which includes: a lock case and a rear mounting plate. An end face of the lock case is provided with a knob attraction plate, and a knob is mounted to the knob attraction plate. The rear mounting plate is attached to the lock case using a snap-fit connection. A transmission gear is installed at an inner side of the lock case, the transmission gear meshes with a motor module, and the motor module is fixed to a motor fixing plate. A gear bore is formed in a center of the transmission gear, a rotary rod penetrates through the gear bore, and the rotary rod is drive-connected to the knob. The rotary rod is connected to a connecting sleeve, the connecting sleeve penetrates through a circuit board to be connected to a deadbolt body, and the deadbolt body matches a plug follower. The intelligent lock device further includes: a door sensor bar and a door sensor plate. The door sensor bar is mounted to the door sensor plate, and a sensor magnet, is mounted at one side of the door sensor plate. The intelligent lock device is novel in structural design. With a door sensor function featuring, strong magnetic sensing, the intelligent lock device can realize automatic locking. Meanwhile, the knob can be detached from and attached to a rear lock body through a strong magnet.

A lock assembly is disclosed that includes a base formed from a magnetic flux conducting material, the base secure to a chassis. A pin slidably disposed in the base and configured to move from a first open position to a second closed position. A magnet, disposed on a surface of a riser and configured to create a force on the pin that causes the pin to move from the open position to the closed position when the riser is disposed with the chassis.

A locking apparatus for a sliding closure slidable within a frame is disclosed. The locking apparatus comprises at least one locking tang movable transversely to the closure plane, between a locking position and a release position wherein, when in the locking position the locking tang extends laterally, in a direction transverse to the closure lane, beyond the closure to be received within a corresponding locking recess in the frame, such that the locking tangs resist opening of the closure, and when in the release position the locking tang is withdrawn within the dimensions of the frame, such that the closure may be opened or closed. The locking mechanism may also comprise a sensor configured to detect when at least one of the locking tangs are in the locked or released position, and, optionally to trigger an alarm if the locking tang is disengaged.

The present invention relates to a bidirectionally operating warfare lock mechanism (C) that prevents external interference (opening/unlocking) to hatches in military vehicles (A) during combat. The present invention particularly relates to a bidirectionally operating warfare lock mechanism (C) comprising a lock operating mechanism (100) that is connected to the vehicle (A) and that allows for opening and locking the hatch (B) when the user moves the lock lever (110) to P1 (161) and P2 (162) receptacles, and further comprising a lock bolt mechanism (200) that can be easily mounted by being rotated 180° around its axis without making any changes in the design, thereby allowing for being used in always-open or always-closed (locked) configurations according to the desired scenario.

Disclosed is a lever-type door lock driving assembly which can be installed inside a mounting hole to enable miniaturization of the device, ensure general versatility, and prevent a fragile area from being generated inside the door. The present invention relates to a driving assembly for a lever-type door lock arranged in an installation hole to drive a latch operating body, wherein the mounting assembly comprise a mounting module having a truncated disc shape and having at least one driving plate therein; and a motor unit mounted on the truncated area of the mounting module and having a disk shape in a state of being coupled to the mounting module.

A clutch engagement assembly for a door lock device includes a first shaft having at an end thereof an insertion end portion in which a channel is formed; a second drive shaft having a hollow engagement end portion into which the insertion end portion of the first shaft is inserted; a driving member which provides a driving force; and a pin member that is installed in a state of being elastically supported in the engagement end portion of the second shaft and is movable by the driving member so as to extending through (be inserted in) at least a part of the first shaft and at least a part of the second shaft, thereby causing a clutch engagement or a disengagement between a first shaft and a second shaft. The clutch engagement assembly may provide a relatively small size structure of the door lock device and a firm engagement force.

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.
