The present invention relates to an improved carabiner system, including an impact-dampening cushion around the external surface of the frame for cushioning damage during a fall or collision and to reduce sound from loose or swinging carabiner collisions. Additional surface routing and through holes provide improved register between the carabiner frame and the over-molded cushion layer.

Disclosed are a door lock and a door system, the door lock includes: a lock body, the lock body including a lock case, a spring bolt assembly and a shifting sleeve, the spring bolt assembly being slidably arranged in the lock case, so as to be able to extend and retract relative to the lock case, the shifting sleeve being rotatably arranged in the lock case, and the shifting sleeve being in transmission connection with the spring bolt assembly; and a first handle assembly, the first handle assembly being provided with a locking head and a motor, the locking head being rotatabversly provided with a shifting head, the shifting head being in transmission connection with the shifting sleeve, and an output shaft of the motor being in transmission connection with the shifting head, so as to be able to drive the shifting head to rotate.

An electronic lock having a lock box arranged in the jamb and a face plate arranged in the door edge, the lock box has a brake gear with a screw sleeve arranged on a screw rod for driving the screw sleeve to displace back and forth, and by driving the rear end of the latch bolt, make the front end of the latch bolt be able to rotate inside the containing space of the lock box and go into or out of the bolt slot, and further goes into the lock slot of the face plate to achieve locking status; or the restoring of the expansion spring makes the latch bolt returned to the containing space to become unlocking status. Because the latch bolt is using the rotation to go in or out of the bolt slot and the screw sleeve and the screw rod which driving the latch bolt has the characteristic of high torque transmission, the present invention can ensure the operation stability of the lock during the locking and unlocking process.

The invention describes a locking device for a fuelling or charging recess, and a fuelling or charging recess, wherein the locking device has a locking pin (12) that has a locking section (14) on one end and can be translationally and rotationally moved for locking. The locking pin (12) has, on the locking section (14), a first holder (16) in which a pressure piece (20) is received that provides a tolerance compensation over the long term. A fuelling or charging recess having a locking device (10) of this kind further has a recess body, a lever arm and a tank filling pipe or charging module, wherein in an opening of the recess body, a tank filling pipe or charging module is inserted and the lever arm is pivotally mounted. The locking device (10) is arranged such that in the closed state of the fuelling or charging recess, a ball (26) or pressure pin of the pressure piece (20) is at least partially pressed by means of the lever arm into the second holder (22) of the pressure piece (20) against the force of a spring (24).

A lock with a long-travel deadbolt includes a first guide member and a loop-shaped rail. A driving member is slidably mounted to the first guide member and includes a second guide member and a third guide member. A third notch is defined in an underside of the driving member. An extension plate is eccentrically and pivotably connected to the second guide member. An extension slot is defined in the extension plate and the first guide member slidably extends through the extension slot. A stop plate is pivotably connected to the third guide member and has an extension portion which has a corner protruding from a side thereof. The third notch and the corner are located at the rail. When rotating the core, the first guide member moves from one end of the extension slot to the other end of the extension slot, the deadbolt travels at least 22 mm.

A lock with a roller deadbolt includes a driving member having a first slot and a transverse slot. The driving member is connected to a first spring, a second spring and a positioning rod. A deadbolt includes a body, an insertion member, a roller and a slide. The driving member is connected to the body. The insertion member is received in the body. The second spring biases the insertion member. The slide is restricted by the positioning rods of the driving member and has a first guide pin extending through the first slot. The slide is movable along the first slot. The guide hole includes an extension slot and an inclined slot which inclinedly communicates with the extension slot. When in a non-transmission position, the roller protrudes beyond the receiving space. When in the transmission position, the roller does not protrude beyond the receiving space.

A lock with an emergency unlocking feature includes a latch bolt, a top rotation member, a restriction plate and a driving member. The driving member is connected to the deadbolt. When the top rotation member is rotated from a close position to an open position while the lock is locked, a restriction member drives the restriction plate to press a resilient unit. The restriction plate is moved to disengage the engaging member on the restriction plate from the second notch of the driving member. The guide slot of the transmission plate pulls the second guide member to move the deadbolt to the unlocked position, and the latch bolt moves to the open position. When in an emergency situation, the user rotates the handle to retract both of the deadbolt and the latch bolt without using a key to unlock the deadbolt to save time.

A lock with replaceable modules includes a first part and a second part which is connected to the first part. The lock has a latch bolt recess, a restriction recess and a deadbolt recess so as to selectively install a latch bolt, a restriction bolt and a deadbolt. A lock block is selectively installed in the restriction recess. The lock includes an installation slot which can be selectively oriented in different directions, and a core recess for receiving the deadbolt. The lock is selectively installed with different components by features of modularization and normalization so as to reduce inventory pressure. The customers may install the lock to entrance doors, gate doors, storage room doors, emergency doors, room doors, bathroom doors or the like.

A retrofit latch adapter is configured to replace a pre-existing roller head latch assembly of a pre-existing exit device. The retrofit latch adapter may include a flat latch head that may provide additional security for a door compared with the pre-existing roller head pre-existing latch assembly.
