A door lock for a handle, comprises a housing, a rotatable connector inside the housing, a first elastic element and a second elastic element both arranged inside the housing. The rotatable connector is interacted with the handle. The first elastic element is at least configured to provide a restoring force for the handle to return to its origin position when the handle is rotated upward to lock the door, and the second elastic element is configured to provide a restoring force for the handle to return to its origin position when the handle is rotated downward to unlock and open the door, as well as to provide enough resistance to remain handle at its origin position when the handle is released. The door lock is effort-saving for the users to rotate the handle upward, and also adapted for various handles having different weights, to be remained at the origin position when the handle is released.

A handle-locking mechanism for a door comprises a sliding bar, a locking member and a rotatable member all inside a lock body, wherein the rotary motion of the rotatable member drives an upper latch and a lower latch to a locking position and unlocking position; the sliding bar is slidably arranged inside the lock body and one end of the sliding bar abuts against the bolt, and the sliding bar is provided with a first elastic element, and the sliding bar is pushed against the elastic force from the first elastic element when the bolt retracts; the locking member is coupled with the sliding bar, and when the bolt stretches out, the locking member is brought by the sliding bar to a position to block the rotary motion of the rotatable member.

An anti-unlocked mechanism comprises a transmission gear, a sliding rod, a locking member and a first elastic member. The transmission gear includes an arc surface. An end of the sliding rod contacts the deadbolt of the lock body. The sliding rod is provided with a fixed stopper and a second elastic member. When the deadbolt is retracted, the sliding rod moves with the deadbolt against the elastic force of the second elastic member. When the deadbolt extends, the locking member moves with the sliding rod to block the rotation of the rotating part. The first elastic member comprises first and second protrusions. The second protrusion will not hinder the fixed stopper of the slide rod unless the first protrusion contacts with the circular arc surface, which will block the movement of the locking member to block rotation of the rotating part.

A motor vehicle door lock which is equipped with a locking mechanism substantially comprising a catch and pawl. Furthermore, a locking pin is provided for interaction with the locking mechanism. Furthermore, there is a damping element for a locking mechanism component and/or the locking pin. Finally, the configuration includes at least one spring which is assigned to the locking mechanism. According to the invention, the spring at least partially abuts the damping element.

A vehicle glove box latch includes a housing, a paddle pivotably connected to the housing, a rotor pivotably connected to the housing, a pawl coupled to the rotor and having an end that is engaged with an opening in the vehicle, and a lock barrel mounted to the housing for locking and unlocking the vehicle glove box latch. In a locked state of the lock barrel, the pawl cannot be disengaged from the opening in the vehicle. In an unlocked state of the lock barrel, the pawl can be disengaged from the opening for opening the vehicle glove box. The lock barrel, the rotor and the rotor mounting portion are concentrically aligned along an axis, which reduces the depth of the latch, which reduces the space in the glove box necessary for accommodating the latch, thereby resulting in an increase in the available storage space in the glove box.

The present invention relates to the field of locks and relates to a latchbolt mechanisms, comprising a rotatable latchbolt (16) and an elastic element (17), wherein the rotatable latchbolt (16) is fixedly mounted on a rotatable pin shaft, round which the rotatable latchbolt rotates. Therefore, a rotational unlocking and locking is enabled and is suitable not only for hinged doors, but also for sliding doors. By a rotary movement, actions of door opening and closing are avoided in a usual case.

The present invention relates to a symmetrical and reversible-clutch mortise lock comprising a central follower, a pair of symmetrical lateral followers, each one located on one side of the central follower to be activated by square bars of handles, a spacer which makes the movement of the two lateral followers independent and a motor, which connects to an actuation lever and which is activated when an access code is validated. The lock further comprises a clutch housed and guided in an accumulator arm able to move linearly to be housed in both lateral followers such that the corresponding lateral follower, when activated by the motion of the door handle, pushes the clutch until it makes contact with the central follower and activates the latch of the lock.

A vehicle includes a compartment mounted to a frame of the vehicle. The compartment includes a box coupled to a vehicle in a fixed position relative to the vehicle and a latch system coupled to the glove to allow a user access to the box. The latch system includes a shape-memory alloy wire and a spring that are used during actuation of the latch system.

An exemplary trim assembly comprises a housing assembly, a cam rotatably mounted to the housing assembly, a lift finger slidably mounted in the housing assembly such that the cam is operable to linearly drive the lift finger between a deactuated position and an actuated position, and a locking mechanism operable to selectively retain the lift finger in the deactuated position. The locking mechanism includes an interface member engaged with the lift finger such that movement of the lift finger moves the interface member between a home position and an offset position, a blocking member operable to selectively prevent movement of the interface member from the home position, and a driver configured to move the blocking member between a blocking position and an unblocking position to thereby lock and unlock the trim assembly.

The invention relates to the technical field of locks and discloses an actuator assembly of a combination lock. The actuator assembly includes a fixed motor, a drive shaft fixed to the axis of the motor, a cylindrical spring sheathed on the drive shaft and displaceable axially, a pin installed onto the drive shaft which may screw within two adjacent loops of the cylindrical spring, and a casing installed coaxially with the motor. The casing includes a cavity for accommodating the cylindrical spring, and a second sliding groove formed on the casing, and both ends of the cylindrical spring have a retaining ring extended outwardly from the outer periphery of the cylindrical spring and the retaining ring disposed at the second sliding groove for preventing the rotation of the cylindrical spring.
