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.

An intelligent unlocking device comprises a rear shell, a front shell, a motor assembly, a hollow rotating shaft, an adapting piece connected with a lock cylinder and the hollow rotating shaft, a manual rotating shaft, an inner bearing and a bearing support which are disposed around the manual rotating shaft, and an outer bearing. The bearing support and the outer bearing are disposed around an end of the manual rotating shaft. The intelligent unlocking device is silent and free of noises in use, and convenient to assemble and disassemble, intelligent unlocking can be achieved without replacement of a whole door lock, and costs are reduced for users.

A door latch assembly is provided with enhanced acoustic dampening characteristics, and includes a door bolt assembly having an inside barrel and an outside barrel configured for accommodating reciprocal sliding action of the inside barrel between a latch position and a release position. At least one barrel acoustic isolator is associated with at least one of the inside barrel and the outside barrel, and is configured for dampening sound generated by the reciprocal action.

A door latch mechanism including a latch housing, a bolt having a proximal end with a head and a distal end having a latch, a hub including a central bore for receiving a spindle, a lever actuated by rotation of the hub, the lever including a slot in a top portion of the lever receiving the head of the bolt such that the lever and the bolt move together in both rearward and forward directions.

An exemplary trim assembly includes a mounting bracket and a lever pivotably mounted to the mounting bracket. The lever is pivotable between an actuated position and a deactuated position, and is biased toward the deactuated position. A bumper is mounted to the mounting bracket and engages the lever when the lever is in the deactuated position.

A system for ensuring that a door automatically closes and latches while simultaneously ensuring that it does so in a manner which either eliminates or significantly minimizes the amount of noise such closure causes while making sure that the door does in fact fully close and latch. A door mounted portion includes a piston attached to a pivotable arm having a wheel on the end of the arm configured to engage with a doorframe mounted portion to slow the travel of the door into the doorframe while pulling the door into the doorframe to ensure secure closure of the door. A doorframe mounted striker plate portion is configured with at least one spring-loaded striker damper or flap against which a door latch and/or automatically deploying deadbolt lock engages, to slow the engagement of the door latch or deadbolt with striker region in the frame to minimize noise.

An exemplary damper module is configured for use with a latchbolt assembly, and generally includes a mounting bracket, a first slowing mechanism, and a second slowing mechanism. The latchbolt assembly generally includes a drive member, a latchbolt, and a retractor connected between the drive member and the latchbolt. Each of the slowing mechanisms is independently operable to slow the extension speed of the latchbolt. The first slowing mechanism includes a rack gear and a rotary damper including a pinion gear. The rack gear is configured to be mounted to the drive member, and the rotary damper is mounted to the mounting bracket. The second slowing mechanism includes a slowing arm and a biasing member engaged with the slowing arm. The slowing arm is movably mounted to the mounting bracket and is configured to engage the retractor.

A motor vehicle latch, in particular a motor vehicle backrest latch, which is equipped with a locking mechanism consisting substantially of a catch and a pawl. A latch housing having a recess is also implemented. In addition, a damping means at the end side of the recess, a latch holder entering the recess in the direction of entry transferring the locking mechanism to its closed position, thereby moving against the damping means. In addition, the damping means has a plurality of recesses and at least one web. According to the invention, the web is designed as an arched web and its highest arch is convexly curved against the direction of entry of the latch holder.

A door striker has an improved cross-sectional shape so that a latch can be maintained in close contact with the striker without back-and-forth clearance. In contrast, with conventional strikers, a door may make noise by being shaken due to application of external forces including changes in indoor and outdoor air pressure. Door strikers described herein include a latch assembly on a side surface of a door, which is connected to and operated by a handle member. A striker, to which a latch of the latch assembly is fitted, is installed on a door frame. The striker has a front latching protrusion for latching a front surface of the latch and a rear latching protrusion for latching a rear surface of the latch. The front latching protrusion has a right-angled surface of a front end thereof and an inclined surface the inside thereof.
