The lock according to the invention is meant for locking cabinets, vaults and different machines. The lock has a lock frame, which comprises a bolt. A lock cylinder has been arranged in connection with the lock frame. The lock frame further comprises a power transmission mechanism between the lock cylinder and the bolt. The power transmission mechanism comprises a transmission lever and a latch. The transmission lever additionally comprises a retaining protrusion. The bolt comprises a locking pin and the lock frame additionally comprises a hole for the locking pin. The lock is arranged to allow movement of the lock cylinder and the power transmission mechanism in the direction of the longitudinal axis of the lock cylinder due to an external hit or drilling of the lock cylinder, whereby the movement in the direction of the longitudinal axis moves the retaining protrusion away from the locking pin. Thus, the end of the locking pin moves into the hole in the frame.

A security apparatus for a doorway includes a plate having a plurality of receiving holes and a plurality of fastening holes. One side of the plate has a formed portion which is bent to be off plane with the plane defined by the remainder of the plate. The receiving holes may be of different sizes to accommodate different bolts. The fastening holes may include one or more groups of fastening holes. In one example the plate has three groups of fastening holes that may be off center from the plate's centerline. The groups may be positioned away from the centerline either toward or away from the formed portion. At least one group is staggered compared to at least one other group. And, at least one group has a spacing between adjacent holes that is greater than the spacing of at least one other group. At least one receiving hole may have one or more filleted corners.

A door position sensor of an electromagnetic door lock. The electromagnetic lock also includes an electromagnet and a strike plate. The electromagnet is secured to the door frame and the strike plate is movably mounted to the door so that a controlled amount of door movement in the opening direction is permitted while the strike plate remains in contact with an energized electromagnet. The door position sensor may comprise a sensor in or on the electromagnet and a permanent magnet mounted to the door and disposed in proximity to the sensor when the door is in a closed position. The sensor may be a reed switch or a Hall Effect sensor. The permanent magnet and strike plate may be mounted to the door by a mounting tray. The mounting tray may include indicia to aid in providing a proper alignment of the strike plate to the door and electromagnet.

A structure of lock includes a core shaft, a swing arm, a push bar, and a keeper plate that are arranged in a lock. The swing arm is arranged at one side of the core shaft to selectively push or separate from a bolt. The push bar is arranged on an axle and has a top edge forming a notch. The keeper plate includes an elongate slide hole formed therein and an elongate positioning hole also formed therein and located below the slide hole. The slide hole is slidably fit over the axle and the positioning hole is slidably fit over a bar in such a way that the keeper plate is movable up and down along a curved path.

The present invention discloses a lock system, comprising a lock assembly that includes a hasp and an interlock mechanism detachably engaging with the hasp. Further included is a latch system that latches the interlock mechanism in a lock position.

An electronic door lock is operable to control access to an access controlled area adjacent the inner side of a door. The door lock includes an outer base, an inner base, a locking mechanism movable between a locked and unlocked position in response to a control signal, and a control circuit disposed within the inner base and operable to generate the control signal in response to the presentation of an input credential. A plurality of different types of credential readers are each selectively attachable and removable from an attachment interface when the outer base is attached to the door to electrically connect the selected one of the plurality of different types of credential readers to the control circuit. The selected credential reader receives data from a user or credential and generates the input credential. A communication module is operable to communicate with a device separate from the electronic door lock.

Wood or metal wedge with metal plate attached to bottom by two or more screws. Front extends beyond wedge to allow it to slide beneath even tightly fit doors. Base plates are interchangeable to accommodate different floor surfaces. Metal base has two or more rows of triangular spikes designed to specifically engage with various types of carpet commonly found in commercial office buildings. The spikes are fine enough to engage the carpet regardless of the direction of the pile, yet sturdy enough to withstand repeated attempts to force door open. There is an optional handle that can be screwed into the back of the wedge.

A bolt assembly usable in a mortise lock. The assembly includes a bolt and tailpiece that are pivotable relative to one another. In one embodiment, the bolt and tailpiece are joined by a pin that permits the components to pivot relative to one another.

Systems, methods, and apparatus are disclosed involving a door blocking apparatus to reduce a likelihood of, and possibly prevent, opening of a door by unauthorized personnel. The apparatus may be networked in a security system and may be connectable to an online security platform. In a particular embodiment, an embodiment of the invention may include a security system involving a plurality of door locations having a plurality of networked door blocking apparatus. Each door blocking apparatus may include a door blocking mechanism operable by a user on a safety side of a door, such as having the user rotate an apparatus handle that rotates the door blocking mechanism between a non-blocking position and a blocking position. In the non-blocking position, the door blocking apparatus does not block the door from opening and closing. In the blocking position, the door blocking apparatus blocks the door from opening and from closing completely.

An auxiliary lock includes an inside housing mounted to a lock cylinder and a first flange extends axially from one of two ends of the inside housing. A mounting plate is mounted to the lock cylinder and contacts the inside housing. The mounting plate includes a second flange which is mounted to outside of the first flange of the inside housing. The lock cylinder is protected and reinforced in the radial direction by the overlapped first and second flanges. When the inside housing is hit, the inside housing does not expand outward to be pried up. The reinforcement structure is made by way of pressing to use less material and to reduce the manufacturing cost.
