A cabinet lock includes a latch configured to translate between extended and retracted positions and a lever configured to rotate between engaged and disengaged positions. The latch may be coupled to the lever with a pin in a corresponding slot. When the lever is in the disengaged position the latch may be in the extended position and when the lever is in the engaged position the latch may be in the retracted position. The lever includes a ferromagnetic portion responsive to a magnet within a threshold distance, where the presence of the magnet moves the lever to the engaged position.

A sliding bolt latch as disclosed herein is convenient to use and more reliable than counterpart door locking mechanisms of the prior art. A user may open and close a door with only one hand, but the present mechanism requires both a rotational movement and a translational movement of elements against a biasing force. Such requirement makes opening doors much more difficult for livestock confined to spaces by the closed doors. Also, the biasing of elements into the locking state makes embodiments of the invention less likely to unlock inadvertently in the presence of ambient vibrations.

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.

A door silencing mechanism and methods to eliminate latch noise associated with a door latch having a spring latch bolt and a bolt housing are described. This mechanism and methods can include an actuator having a first end and a second end and moveable between a first position and a second position. This mechanism can also include a device coupled to the first end of the actuator to maintain the spring latch bolt within a bolt housing using the second end of the actuator when the device holds the actuator in the first position and to release the spring latch bolt from within the bolt housing by moving the second end of the actuator in response to the actuator moving to the second position in response to contact with a doorjamb.

Door locks, door locking and unlocking methods, and door security and communications devices are provided, and can include an exterior module mountable on an exterior surface of a door; an interior module mountable on an interior surface of a door; a deadbolt movable between an unlocked position allowing opening of the door from a closed state and a locked position preventing opening of the door from the closed state; a camera and/or a microphone provided on the exterior module; and a wireless communication device configured to communicate images from the camera and/or sound from the microphone to a smart phone or computer of an authorized user for remote observation of an area adjacent the exterior surface of the door.

A luggage includes a case member having an opening; a front cover connected to the case member to open and close the opening of the case member; a lock member connected to the case member, wherein the lock member has a hook portion, and the hook portion has a bore; a lock base connected to the front cover; a latch movably connected to the lock base; a spring having opposite ends urging the latch and the lock base; and a lever member pivoted lock base and associated with the latch. The latch engages the bore of the hook portion to lock the front cover with the case member, and the lever is turned to move the latch and disengage the latch with the bore of the hook portion of the lock member to unlock the front cover with the case member.

An improved door lock mechanism is a door locking device having heavy plates that sandwich the door frame above or below the door knob of a door with bolts passing through the plates to secure it to the door frame, and a barrel lock accessible through the outside plate with a barrel key. The locking mechanism is attached to a locking bar on the inside that is attached to a lock shaft rotatable on the door frame side which rotates downward into a slot formed in a plate that is attached to the inside of the door adjacent the frame plates. Together the frame plates, the door plate, and the rotating bar function as a door bar.

A low profile actuating window lock for casement windows having a longitudinal slot in a sidewall of the casing for the lock, wherein a fork component translates within the slot in a direction perpendicular to an axis of rotation of the handle and the handle rotates along a plane perpendicular to the fork component, the handle pivotable about a restrictor arm that pivots relative to the casing, allowing the handle to rotate fully from the locked position to the unlocked position with low clearance from the window frame. The pivot points of the handle and restrictor arm configuration allow for an over center linkage that prevents back driving the casement window lock.

A retention bracket configured for use with a latch mechanism including a laterally extending housing. The retention bracket includes a first wall, a second wall, a collar, and a deformable section. The first and second walls are longitudinally offset from one another and are structured to receive the housing therebetween. The collar extends longitudinally outward from one of the walls and defines an opening having an effective diameter. The deformable section has a natural state in which the effective diameter is a first diameter, and a deformed state in which the effective diameter is a second diameter greater than the first diameter.

A locking device for a window or a door, wherein the window or the door has a sash slidable in a horizontal direction within a frame. When a user turns on a switch to control a block to move from the first position to the second position, the block protrudes out of a vertical surface of the sash, thereby driving a linkage member to disengage from the frame. At this time, the user could hold and push the block in the horizontal direction to move the sash between a third position and a fourth position. When the sash is pushed back to the third position, the block could be controlled to move back to the first position, namely back to a mounting groove, thereby moving the linkage member to a position where the linkage member is engaged with the frame. A method of operating thereof is provided as well.
