A door lock system includes an escutcheon with a keyless cylinder handle. A locking block is disposed in the handle cylinder and spring biased to a locked position to prevent removal of the handle. The locking block may only be moved to an unlocked position by accessing a lock spindle extending through an opening on a rear side of the escutcheon mounted to the door.

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.

A door latch (100, 400, 500, 600, 1200, 1300, 1400, 1500, 1600, 1700, 1800, 1900) resists opening of a door (200) beyond a predetermined amount when it is engaged and also allows the opening of the door when it is disengaged. The door latch includes a catch (220, 220′, 3220) and a base (191) that is connected to a deformable member (140, 3140, 4140, 5140, 6140) at a joint (90). The joint configures the door latch and may include a pin (190). The catch (e.g., a hook) engages a catching portion (e.g., a loop 148, 3148, 6148) of the deformable member when engaged. The deformable member may stretch at least five percent when resisting an intrusion load (F) on the door. The base may mount to a door frame (300), and the catch may mount to the door. A spring (180) may urge the deformable member toward engagement. A shield (280, 2280, 4280, 5280, 6280) may protect the deformable member and resist cutting and may pivot with the deformable member urged by the spring. A finger pocket (296) may be used to overcome the spring. A detent (187) may retain a disengaged configuration (70), and a button (130) on the pin may be depressed to release the detent. A keeper (260) may retain an engaged configuration (50), even when the intrusion load alternates. An armed configuration (40) may automatically transition to the engaged configuration upon the door reaching the predetermined amount and may be manually transitioned to the disengaged configuration upon operator manipulation. The deformable member may hyperelastically deform.

The invention relates to a lock (5) for a hinged closure, comprising a housing (8) adapted to be mounted on a frame (3) of the closure, and seating internally thereof a bolt device (4) reciprocable relative to the housing between respective open and closed positions of the closure and having a throw of substantially 70 mm to bridge in use a gap between the frame and a facing keeper, characterised by a Eurocylinder lock means (5) adapted to engage and retain the bolt (4) in the locked, or closed, position of the closure. There is also disclosed means to protect the said lock (5) against vandalism, the means comprising in disclosed embodiments a cover plate (305,305a), an inclined escutcheon (6), or smooth fillet weld(s) securing the escutcheon (6) to the housing (8).

A rolling door lock for a roll-up door, and more particularly a roll-up door that includes a latching handle assembly fitted to the exterior surface of a roll-up door. The latching handle assembly includes a handle and a hook. The rolling door lock attaches to the hook and handle of the latching handle assembly to prevent forced opening of the roll-up door. The rolling door lock includes a main body and a detachable bracket. The main body includes a hook securing portion and a pocket. The pocket includes a slot. During normal use the hook securing portion of the rolling door lock secures the hook of the latching handle assembly, and the detachable bracket secures the handle of the latching handle assembly. The lock mechanism locks the detachable bracket with the handle secured therein to the pocket.

A closure is provided for a pressure vessel or pipelines that can provide quick and easy access to the interior of a pressure vessel or pipeline, and means for a pressure tight seal between the hub and door. The closure can incorporate means for mechanically fastening the door to the hub using an external split clamp ring actuated by a toggle mechanism. A locking mechanism can be provided to safeguard against unintended closure actuation, and provides a layer of redundancy to the holding characteristics of the toggle mechanism. The locking mechanism can be interlocked to a pressure alert system to ensure any differential pressure condition contained within the closure is detected prior to disengaging the locking mechanism and actuating the toggle mechanism.

A lock with a sole plate and a slider, guided in translation relative to one another by a guide between two positions, an extended position and a retracted position. The slider includes a bearing surface which extends in a sliding plane defined by the guide and an indentation relative to the bearing surface forming a translation stop in one of the two positions. The sole plate cooperates with a retractable pin of a lock carried by the slider, to lock it in the extended position and in the retracted position. The slider comprises, opposite the indentation relative to the retractable pin of the locking means, a translation stop in the extended position.

A strike plate mounting bolt assembly for resiliently mounting a strike plate to a door. The strike plate mounting bolt assembly includes a bolt and a post wherein the bolt is securably engageable with the post. The bolt is inserted through a bore in the door and the post is inserted through a bore in the strike plate. A resilient member such as at least one Belleville washer is disposed between a head of the post and a cavity in the strike plate wherein the at least one Belleville washer is compressed between the post head and cavity upon securing the bolt and post together to provide a resilient mount between the door and strike plate. The at least one Belleville washer may be a number of Belleville washers selectable stacked to form a pack of Belleville washers. By varying the number and orientation of the Belleville washers, the force/deflection characteristics of the pack may be tuned to accommodate the needs of a variety of electromagnetic lock design features.
