A closure for a door of a structure, for example, a wildlife observation or hunting blind, is provided. The closure can include a base plate, a door latch, a handle, and at least one tracking bar spaced from the base plate to form a gap, sized to receive part of a door panel. The tracking bar can include a primary sliding surface that faces and slides relative to a first side of the panel when converting the closure from a locked mode to an open mode. The plate can include a guide bar slidable within a panel guide slot coextensive with a transverse opening sized so the tracking bar can fit through it and retain the base plate and handle in sliding relation proximate the panel. The door closure can be installed relative to the door manually, without the use of tools. A related method of use is provided.

An electronic cabinet lock comprises a lock body base (101) and a handle (201), one end of the handle is movably connected with the lock body base, and the other end is attached with an unlocking mechanism and a engaging board (204), a self-holding electromagnet is attached on the lock body base, the self-holding electromagnet comprises an electromagnetic coil (301), a retractable body (302), a first permanent magnet (303), and a biasing structure body (304), when the electromagnetic coil (301) is energized forwardly, the retractable body (302) can be driven to perform a retracting operation, when the electromagnetic coil (301) is energized reversely, the retractable body (302) can be driven to perform an extending operation, a mutual snap-fit between the retractable body (302) and the engaging board (204) is realized and released by relative movement of the retractable body (302) and the engaging board (204) in the retractable direction and the permanent magnet (303) is mounted on an outer side of the hole for movement of the retractable body (302), in order to maintain the retracting state when the retractable body (302) retracts, the biasing structure body applies force to the retractable body (302), in order to maintain the extending state when the retractable body (302) extends. Also disclosed is a control method of the electronic cabinet lock for controlling the electronic cabinet lock.

A security swing handle comprises a housing and a handle pivotally mounted to the housing between a closed position and an open position. A locking insert is rotatably supported in the housing and operatively connected to a latch to actuate the latch to release the handle to an open position. A hasp assembly includes a hasp at the bottom of the housing and a plate member disposed within an interior of the housing adjacent to a bottom of the latch. A pin on the locking insert is disposed within an aperture of the plate member to move the plate member against the latch to release the handle to the open position when the locking insert is rotated. If a padlock locked to the hasp is subjected to blunt force, edges of the aperture shear the pin from the locking insert disabling the locking insert.

A window latch for a sliding window having a sliding sash including a latch plate and a housing. The housing includes an engagement element movable relative to the housing from a locked position operatively engaged with the latch plate to an unlocked position disengaged from the latch plate. A handle is operatively coupled to the engagement element and movable from a first position to a second position in a first direction corresponding to the direction the sliding sash to which the handle is attached moves to an open position. The handle operatively moves the engagement element from the locked position to the unlocked position as the handle is moved in the first direction toward the second position.

This invention is directed to a door handle which is normally hidden within the door, be it either completely flush with a door surface, or partially protruding from said door surface. If a user wants to use the handle, then the user activates the handle using convention actuating techniques to extend the handle from the recess. Should an external object be placed between the handle and the door surface after the handle is operated and the retraction process begins, the handle movement is limited in the downward direction by the extension of an elastic link between the door handle and the rest of the retraction mechanism.

A pressing type latch device includes a seat, a pivotal seat mounted in the seat, and a handle having a grasping portion pivotably connected to two eccentric locations of the pivotal seat, such that a greater operational height can be formed when the handle is lifted. When the latch device is in one of a plurality of retainable open positions or a retainable closed position, the grasping portion of the handle can be moved to a position to lift the pivotal seat, such that the grasping portion of the handle lies flush with the pivotal seat. On the other hand, when the grasping portion of the handle is lifted to move the pivotal seat downward, the handle and the pivotal seat can rotate freely. Since the latch device includes a closed position and a plurality of open positions, the latch device can be installed and used more easily.

A lock, including: a retractable knob; and a knob release mechanism for retaining the retractable knob in a retracted position, wherein the knob release mechanism includes a damper with a gear that is slidably received within a set of grooves located in the retractable knob, and wherein the gear prevents rotation of the retractable knob unless it is in an extended position.

According to one embodiment of the disclosure, a knob to latch interface includes a body, a latch in operable communication with the body movable between a latched position and an unlatched position, and a knob longitudinally positionable between a first position and a second position relative to the body and in operable communication with the latch, an outer radial extent of the knob being operationally engagable only while in one of the first position and the second position.

A compression latch having a body including a cup having a well defining a first side of the compression latch, an exterior portion defining a second side opposite the first side, and a raised portion defining a peripheral rim surrounding the cup, the peripheral rim providing an uppermost surface of the cup is disclosed. The compression latch has a T-shaped handle mounted to the body, the T-shaped handle being foldable and reversible and having a cam lock mounted thereon, the cam lock having a keying element on one side of the handle and a rotatable locking cam on the second side of the handle, wherein when the T-shaped handle is folded in a first position, the keying element is exposed and does not protrude beyond the uppermost surface of the cup and when the T-shaped handle is reversed and folded in a second position, the rotatable locking cam is exposed and does no protrude beyond the uppermost surface of the cup.

A flush-mounted handle assembly for a cargo door having an exterior rotatable handle having a bumper assembly and an interior rotatable handle, a housing having a cavity for receipt of the exterior rotatable handle and an actuator positioned between the interior rotatable handle and housing. The housing having a skid plate positioned within the cavity for receipt of the bumper when the exterior rotatable handle is rotated and the housing also having a shaft removably connected to the housing by a nut for receipt of the actuator.
