A transmission mechanism applied to a lock and for controlling the lock to switch between an unlocked state and a locked state. The lock includes a first handle set including a first cover plate which includes a first fitting portion. The transmission mechanism includes a transmission element and a moving component. The transmission element is connected to the first handle set in a manner that the transmission element is incapable of moving along a rotating axis and has an abutting portion. The moving component is disposed on the transmission element in a manner that the moving component is capable of moving along the rotating axis and includes a first engaging groove, a second engaging groove and a second fitting portion. When the transmission element is operated to rotate, the abutting portion is capable of switching between the first engaging groove and the second engaging groove.

Damped door closer systems, door assemblies including the damped door closer systems, and methods of operating damped door closer systems. The damped door closer systems include a closer assembly and damping assembly connected to each other through a connecting arm.

A door closer is provided. The door closer includes a first connecting plate and a second connecting plate. The first connecting plate is connectable to an external door frame, the second connecting plate is connectable to a door body connecting portion. Connecting rod assemblies and return springs are mounted in the door body connecting portion. One end of the connecting rod assembly passes through the second connecting plate and is hinged to the first connecting plate. When a door is opened, an external door body drives the first connecting plate and the second connecting plate to overturn, and after the connecting rod assembly pulls the door body connecting portion, the return spring is compressed. When the door is closed, the return spring pulls the door body to close automatically.

A hood bumper for a vehicle having a hood including: a housing having a wall, a base, an internal chamber, and an opening to the internal chamber. The wall having an interior surface and an exterior surface. the interior surface defines the internal chamber. The hood bumper further including a biasing mechanism operably connected to the housing and a plunger operably connected to the biasing mechanism and configured to receive an exerted force from the hood. The hood bumper further including a bumper head operably connected to the housing and a support frame operably connecting the bumper head to the housing. The plunger is configured to first move into the bumper head to absorb an impact force to the hood, next the bumper head compresses to further absorb the impact force, and then the support frame collapses to even further absorb the impact force.

A door silencing mechanism and methods to eliminate latch noise associated with a door latch having a spring latch bolt and a bolt housing are described. This mechanism and methods can include an actuator having a first end and a second end and moveable between a first position and a second position. This mechanism can also include a device coupled to the first end of the actuator to maintain the spring latch bolt within a bolt housing using the second end of the actuator when the device holds the actuator in the first position and to release the spring latch bolt from within the bolt housing by moving the second end of the actuator in response to the actuator moving to the second position in response to contact with a doorjamb.

A spindle drive for a closure element of a motor vehicle including a downstream spindle/spindle nut mechanism, a spindle, a spindle nut and a spindle guide tube, for producing drive movements along a drive axis. A number of drive connections adjustable with respect to one another to transmit the drive movements, the first drive connection axially fixed to the spindle guide tube, a second drive connection axially fixed to the spindle, a drive spring configured to produce drive movements along the drive axis, the spindle guide tube has a first outer radius extending along at least one axial portion and on a side facing the first drive connection, a tube end portion with a tube end edge, that the tube end portion is widened radially so that the tube end edge has an outer end edge radius which is greater than the first outer radius.

A refrigerator appliance includes a cabinet defining a food storage chamber. A door is positioned on the cabinet and is movable between a closed position and an open position. A door opener includes a casing, a gear box, a sliding nut movable relative to the gear box, and a finger extending through the gear box. The finger is movable with the sliding nut. The door opener also includes a sensor. The finger extends outside of the casing to contact an inner surface of the door when the door is in the closed position and the door opener is in a zero position. The sensor is configured to detect movement of the door opener from the zero position.

A luggage includes a case member having an opening; a front cover connected to the case member to open and close the opening of the case member; a lock member connected to the case member, wherein the lock member has a hook portion, and the hook portion has a bore; a lock base connected to the front cover; a latch movably connected to the lock base; a spring having opposite ends urging the latch and the lock base; and a lever member pivoted lock base and associated with the latch. The latch engages the bore of the hook portion to lock the front cover with the case member, and the lever is turned to move the latch and disengage the latch with the bore of the hook portion of the lock member to unlock the front cover with the case member.

A hinged mobile computing device includes a first housing part and a second housing part coupled by a hinge assembly having a harness, a harness cover, a first hinge body, and a second hinge body. The harness is configured to accommodate flexible printed circuitry and a cable that extend from the first housing part to the second housing part via the hinge assembly. The hinge bodies include respective friction bands, each friction band being configured to engage a respective shaft formed on the harness and having a gear configured to mesh with a respective cog arranged within the harness cover to coordinate a timing of the rotation of the first and second housing parts between face-to-face and back-to-back orientations. The hinge assembly further includes a spring-loaded opening mechanism.

An exemplary door closer has an adjustable size and includes a rotatable member operable to adjust the size and an indicator mechanism configured to indicate the current size. The indicator mechanism includes a cover mounted to a housing of the door closer and a dial rotatably mounted to the cover. The dial is engaged with the rotatable member such that the dial rotates in response to rotation of the rotatable member. The cover includes an indicating region, and the dial includes a display surface including indicia relating to the sizes of the door closer. The display surface is non-perpendicular to the rotational axis of the rotatable member. When the door closer has been adjusted to a particular size, indicia relating to the particular size are indicated by the indicating region.
