A recliner handle with an overload protection device is provided for a vehicle seat having a recliner attached to a recliner B-bracket. The recliner handle is attached to a handle spline having a disc shaft aperture configured to engage with a disc shaft of the recliner. A stop flange attached to the handle spline is configured to frictionally engage with an overload stop attached to the recliner B-bracket. The handle spline is rotatable in a first rotational direction between a first position wherein the stop flange is frictionally engaged with the overload stop and the disc shaft aperture is disengaged from the disc shaft and a second position wherein the disc shaft aperture engages the disc shaft. Rotation of the handle spline in a second rotational direction from the first position is restricted by the stop flange frictionally engaged with the overload stop.

A gravity-orientation coupler is shown and described. The gravity-orientation coupler includes a first coupler half and a second coupler half, wherein the coupler halves are shaped to fit flush together. Each coupler half is comprised of a tongue having a ball chamber which is located within one end of the tongue. The ball chamber movably houses a ball. The ball chamber has an opening located at one side. The tongue of one coupler half is configured to align with and fit flush against the other coupler half. The ball and ball chamber are configured such that when the coupler halves are fitted together the ball in at least one of the ball chambers will apply pressure to the respective tongue securing it therein.

A fastening structure includes an operating engaging element and a body portion. The operating engaging element has an engaging portion and an operating portion. The operating portion has a moving surface abutting against a corresponding moving surface of the operating engaging element to cause movement of the operating engaging element. The body portion has a mounting portion which the operating engaging element is mounted on; or the operating engaging element has a mounting portion which the body portion is mounted. With the engaging portion, the operating engaging element is fastened to an object, and the body portion is fastened to another object, thereby fastening the two objects together. Unfastening the two objects entails pressing the operating portion such that the moving surface of the operating portion abuts against the corresponding moving surface of the operating engaging element to cause movement of the operating engaging element, thereby separating the objects.

An actuating mechanism includes a target, a smasher, an elastic component, and a blocker. The smasher is movably disposed at a side of the target. The elastic component is configured to provide an elastic force to drive the smasher to move toward the target. The blocker is movably disposed corresponding to the smasher. When the blocker contacts the smasher, the blocker clamps the smasher. When the blocker is moved to a position where the clamping to the smasher is released, the smasher is driven by the elastic force to move toward and smash the target. An electronic device is also provided.

A loading system laterally loads and unloads an upper body structure onto a vehicle platform of a motor vehicle. The system includes two loading arms pivotably mounted on lengthwise ends of the vehicle platform. The loading arms jointly swivel between upward and lateral orientations with respect to the vehicle platform and jointly extend and retract. Each loading arm has an engaging portion at a distal end of the respective loading arm to engage a corresponding support portion at a respective lengthwise end of the upper body structure. The loading arms engage and release the upper body structure by swiveling into the lateral orientation and extending and retracting within the lateral orientation. The loading arms mount the engaged upper body structure on top of the vehicle platform by swiveling with the engaged upper body structure into the upward orientation and retracting with the engaged upper body structure within the upward orientation.

An assembled-type fastener unit includes a base, a handling member movably fitted in the base, and a locking device movably received in the handling member. The handling member can be operated for the locking device to extend out of the base to form a locked state or for the locking device to retract into the base to form an unlocked state. To use the fastener unit, the base is firstly connected to an object. Then, the handling member is operated for the locking device to extend out of the base and lock to a target object to form the locked state; or the handling member can be operated for the locking device to retract into the base to separate from a target object and form the unlocked state. Thus, at least two objects can be repeatedly and quickly connected to or disconnected from one another using the fastener unit.

There is provided a wall port cover to be installed in building wall ports. Wall ports are simply openings in a wall or ceiling of a building which may be used to house electrical panels, HVAC systems, access panels, lighting switches, and the like. The wall port cover comprises an engagement means which is rotatable between an engaging position and a releasing position. In the engaging position, the engaging means extend beyond the wall port cover to engage a top surface of the wall or ceiling drywall panel to support and retain the wall port cover within the vent opening. In the releasing position, the engaging means are retracted within the wall port cover to disengage from the top surface of the wall or ceiling drywall panel to allow the wall port cover to be removed from the vent openings.
