A cooling appliance including a locking mechanism configured to fix the door to the main body at a different position from the latch mechanism, in a state where the door fixed to the main body by the latch mechanism closes the cooking chamber, wherein the locking mechanism provided in the door may include a shaft moved to a fixing position, at which the shaft is coupled to the hinge member, or a releasing position, at which the shaft is released from the coupling state, by a repeated pressing manipulation.

A lock system for controlling access, for example to a room or building, is disclosed. The lock system comprises a bolt module in which control of the bolt can be configured differently on the two sides of a leaf or door. Control of the bolt module may be provided by various locking modules, which are also disclosed herein. The bolt module is reversible for left handed or right handed operation. In one embodiment the bolt module comprises: a bolt moveable between a thrown position and a retracted position; and a first rotor assembly capable of accepting a drive element, the first rotor assembly arranged to drive the bolt. The bolt module may also comprise a second rotor assembly. The bolt module may comprise an anti-thrust member obstructing driving back of the bolt under action of an external force on the bolt. The bolt module may comprise a lockable cover.

A locking device includes a locking pair having a bolt to engage with a retainer and a detection linkage. The bolt is movably mounted against a spring which tends to return the bolt to a position spaced apart from the retainer. The detection linkage is also movably mounted between an unlocked position where the detection linkage allows unlocking of the bolt and the retainer. In particular, a portion of the bolt then engages with the detection linkage by means of a detecting part of the detection linkage to block a possible return of the detection linkage towards a locked position where the detection linkage engages with the portion of the bolt so as to oppose to unlocking of the bolt. The detecting part irreversibly drives the detection linkage to its unlocked position even when one locking pair is unlocked.

A panel restrictor for a heating, ventilation, and/or air conditioning (HVAC) unit includes a first bracket configured to couple to a structural support of the HVAC unit, where the first bracket includes a slot. The panel restrictor includes a second bracket configured to couple to a panel of the HVAC unit. An arcuate segment extends from the second bracket and is configured to extend through the slot. The panel restrictor also includes an engager configured to secure the arcuate segment within the slot at a plurality of discrete positions along the arcuate segment.

In several embodiments, a person trapped inside a cooler may utilize the cooler safety release device to escape. The person may place his fingers on a pull tab on the inner plate of the safety release device and slide the inner plate away from the outer plate to move the locking tab away from being immediately above the plate of the locking mechanism to being adjacent, but no longer overlapping, with the plate of the locking mechanism. In one or more embodiments, when the locking tab is positioned in a non-overlapping position with the plate of the locking mechanism, the lid is unlocked from the cooler body and is able to be opened, even by someone inside the cooler.

A lock mechanism for interengaging two relatively movable components includes a bolt mounted within a first component and interengageable with a second component when the first and second components are in a predetermined position relative to each other and the bolt is extended. A magnetically-releasable latch mechanism is positioned to latch the bolt in a retracted position and is mounted for movement between a biased latch engaging position and a latch releasing position in a non-common direction of movement of the bolt. A first magnet is disposed within a trigger being translatable along an axis parallel to a longitudinal axis of the bolt and a second magnet is positioned to displace the latch mechanism to the latch releasing position as the trigger is caused to translate vertically when the first component is in the predetermined position relative to the second component to permit displacement of the bolt to the extended position.

An intelligent door lock system coupled to a door at a dwelling. a door status device is at the dwelling. The door status device is coupled to a drive shaft of a lock device to assist in locking and unlocking a lock of a lock device at the door. The lock device is coupled to the door status device and includes a bolt. An engine, an energy source and a memory are coupled together. A camera is coupled to or part of the intelligent door lock system. The camera is configured to record in response to door lock status.

The present invention relates to an installation structure of an auxiliary locking device for a hinged door, and by operating a rotation lever installed on a door frame separately from a generally used security main locking device, the rotating opening side of the hinged door is vertically attached to the door frame in close contact with the door frame at a number of points in the longitudinal direction, and in order to make it easier to fix and maintain such a tight state. More particularly, the present invention is directed to providing new installation structure of the auxiliary locking device of the hinged door capable of preventing the mutual interference of the driving plate and locking piston, even if the longitudinal installation range of the driving plate is overlapped with the operating range of the locking piston constituting the second locking tool.

Disclosed is a refrigerator, more particularly a refrigerator including dual doors that are convenient to use. The refrigerator includes a main body having a storage space therein, a first door hinged to the main body for opening and closing the storage space, a door frame provided at the first door, a second door hinged to the first door, the second door having a side wall, at least a portion of which is inserted into the door frame, and a catching part provided in the side wall, and a locking device for selectively allowing the second door to be turned with respect to the first door, wherein the locking device includes a moving member, the displacement of which is changed depending on the open or closed state of the first door, and a catching member, the displacement of which is changed depending on the displacement of the moving member, whereby the protruding length of the catching member from the door frame is changed, the catching member being selectively caught in the catching part.
