A door lock chassis has a gauge insert that defines different dimensions corresponding to different door thicknesses. The gauge insert is positionable in the lock chassis in different orientations corresponding to the different dimensions used to align the lock chassis for different door thicknesses. Additionally, a door lock may include an anti-rotation assembly for preventing rotation of the lock chassis. The anti-rotation assembly may include a retention member that is secured to an inside hub of a lock chassis. As an anti-rotation member is displaced in a first axial direction along the inside hub to a mount position, the anti-rotational member may deflect resilient members of the retention member. With the anti-rotation member at the mounted position, the anti-rotation member may be in a frictional engagement with the previously deflected resilient members so that anti-rotation member is retained at the mount position.

A handle and latch assembly is provided for a vehicle door and includes a housing, a latch on the housing and a handle on the housing. A mounting bracket secures the housing to the door using screws with the door being sandwiched between the housing and the mounting bracket. The mounting bracket can be positioned in multiple orientations to accommodate doors having different thicknesses. The housing includes tapered pins that that press fit onto the mounting bracket to provide a temporary hands-free positioning of the assembly into the door until the mounting screws are installed.

A cam lock for cabinets, drawers, drug cabinets, credenzas, sliding doors, lockers, mail boxes and other door type applications is compact in size, fits an existing cam lock opening and provides electronic access via a keypad or other electronic access. Using batteries, such as AAA size batteries or smaller, the lock has electronics that release a lock turn knob or handle when the correct code is entered. Preferably a set of electronic contacts is included at an accessible position on the lock housing to allow both master access and power jumping with a common manager's implement, for situations of lost codes and/or battery failure. In a particular embodiment the lock is long, narrow and low in profile so as to fit on the margin of a steel or wood file cabinet, compatible with the cam lock opening already provided. The locks, NFC-enabled, can be used in securing delivery boxes to enable delivery access, when authorized.

A hub assembly for a door handle includes a hub body that extends along a longitudinal axis and has a first end portion including a spindle recess and a second end portion including a handle attachment protrusion. A spindle slideably received within the spindle recess in the first end of the hub body. A spring at least partially located within the spindle recess on the hub body and in engagement with the spindle.

A handle assembly, including at least: a first handle including at least one recess and a square spindle configured to be received at least partially within the recess of the first handle, in an initial configuration, the first handle is configured to slide freely along the longitudinal axis of the square spindle over a given distance, the first handle is configured to pass from the initial position to a securing configuration in which the first handle is immobilized in translation and in at least one direction of rotation with respect to the square spindle, by at least one displacement in rotation of the first handle about the longitudinal axis of the square spindle through an angle strictly less than 360°.

Lock indicators useable to signal the locked or unlocked state of a lock where the lock indicator is usable with an adjustable rose for accommodating various door thicknesses.

A double-sided gate handle device is described. The device includes a first portion, a second portion, and a third portion. Each of the first and the second portion comprise a plate having a first side disposed opposite a second side and a handle extending from the first side of the plate. The third portion is disposed perpendicular between the second side of the first plate and the second side of the second plate such that the third portion contacts a peripheral edge of the second side of the first plate and a peripheral edge of the second side of the second plate. The second side of the first plate is separated by a distance from the second side of the second plate. The second side of the first plate is configured parallel to the second side of the second plate. A gate is configured to be received within the distance.

A dual action latch, having a latch handle, an elongate bolt, a cam, a latch housing, and a biasing device, for installation on one side of door. The latch handle includes a lifting portion and a lever arm. The latch housing has a lever arm aperture through which the lever arm of the latch handle passes and a bolt guide for slidably receiving the elongate bolt. The latch handle is movably attached to the latch housing. With the latch handle moved, the lever arm withdraws the elongate bolt into the latch housing. Independently, when the cam is rotated by a separate handle on the other side the door, the cam plate likewise withdraws the elongate bolt into the latch housing.

Locking device is disclosed for parcel boxes or lockers. The device comprises a user operable handle and a lock mechanism comprising a motor to rotate a pinion to move a rack attached to a handle-blocker and to a deadbolt. The handle-blocker controls transition of the user operable handle between open and closed positions due to movement of the rack, and simultaneously the deadbolt is configured to move between locking and unlocking positions. In the closed position, the handle-blocker and the handle-body have a linear connection with each other and in open position this connection is lost. The handle may be activated by tapping the handle-cover, or by using an RFID, NFC or by mobile technologies. A method to operate opening and closing a parcel box locked with the locking device allows one or more users to access the parcel box via software application paired with the device.

In one embodiment, a system includes a first object, a second object, and a latch. The latch includes a worm gear, a spur gear, and a lever arm. The spur gear rotates in response to rotating the worm gear. The lever arm rotates in response to rotating the spur gear. The first object latches to the second object in response to rotating the lever arm.
