In an exemplary embodiment, a locking holder with a mounting element in which the locking holder can be fastened to a door frame in a mounting plane, and with a holding surface which is arranged spaced apart with respect to the mounting plane and can be engaged behind by a door-side locking latch in order to lock the door, the holder includes a holding shoe which can be fastened releasably to a holding element in order to set the distance of the holding surface with respect to the mounting plane.

Various disclosed embodiments include a lock assembly and hinge assembly. The hinge assembly has a security engagement extension feature. The hinge assembly also includes a receiver. The receiver has a receiving area for receiving at least a portion of the security engagement extension feature and the receiver has a receiver security engagement feature formed as part of the receiver. The receiver security engagement feature is complementary to the security engagement extension.

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.

Provided is a refrigerator having only a second door opened/closed or having both of a first door and a second door opened/closed using one handing by allowing a latch device to fix the second door to the first door or release the second door from being fixed to the first door. The refrigerator includes a main body having a storage compartment, a first door that is rotatably disposed in front of the main body and has an opening formed therein, a second door that is rotatably disposed in front of the first door to open/close the opening, a handle coupled to a front side of the second door to open/close the first door and the second door, and a latch device allowing the second door to be fixed and released to/from the first door.

The present latch apparatus includes a swinging piece having first and second independent latches or sliders sliding in first and second slots. The first and second sliders slide independently of each other. The first and second sliders engage an undersurface of an extension of a first object such as a gate. If either the first or second slider is engaged on the undersurface, the swinging piece is locked and is not swingable such that the first object such as the gate cannot itself swing away from a second object such as a barrier section. Only when each of the first and second sliders has been slid beyond the undersurface can the swinging piece swing to permit the first object such as the gate to be released and thus swingable itself relative to the second object such as the barrier section.

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.

A lockable bolt device for an interior of a door. The lockable bolt device includes a door attachment plate having a horizontal aperture therethrough, configured to securely attach to the door, and a jamb attachment plate having two horizontal apertures therethrough, configured to securely attach to a door jamb. The jamb attachment plate also includes a vertical aperture therethrough, such that the vertical aperture is configured to removably accept an angled bolt therethrough for storage of the angled bolt when the lockable bolt device is in an unlocked configuration. When the door is in a closed position and the horizontal apertures are aligned, the two plates are configured to accept the angled bolt through the horizontal apertures to secure the door in the closed position. The lockable bolt device is useful to prevent an individual from passing through the door from an exterior of the door.

A hatch locking device for an aircraft hatch includes an eccentric bush which can be connected to a hatch bulkhead of the aircraft hatch panel, an inner lining which is introduced into the eccentric bush and has a bolt receptacle which is oriented centrally along a bolt receptacle axis for receiving a locking bolt, a conical pressing sleeve in the inner lining, a conical clamping sleeve, the outer conical shell face of which is in displaceable engagement with an inner conical shell face of the conical pressing sleeve, and the inner cylindrical shell face of which is flush with the outer wall of the bolt receptacle, and linear actuators which are mounted on in each case two opposite sides of the conical pressing sleeve in the inner lining and are designed to displace the conical pressing sleeve along the bolt receptacle axis with respect to the conical clamping sleeve.

Provided is an electronic lock featuring foolproofness and repositionability, including: a lock body, which is formed with teeth and a receiving cavity; a repositionable plate, which is formed with an elongated hole, a perforated portion, and a projecting spot, and is formed, on an underside thereof, with teeth, such that the teeth of the underside of the repositionable plate and the teeth of the lock body are mutually engageable with each other and the elongated hole of the repositionable plate is fixable to the receiving cavity of the lock body by a fastening element, and an escutcheon, which is formed with a fixing hole and a foolproof hole, such that the escutcheon is fit, by means of the foolproof hole, to the projecting spot of the repositionable plate and the escutcheon is fixed to the perforated portion of the repositionable plate by a fastening element.
