To help hold a (trailer) bed of a truck or trailer steady at a loading dock as the truck is being loaded or unloaded of its cargo, a yieldable vehicle brace exerts a substantial, but limited, reactive force upward against the trailer's rear impact guard to resist the trailer's downward movement. In some embodiments, the brace holds the trailer bed stationary up to a certain load limit and provides the trailer bed with a controlled or dampened descent when the load exceeds that limit. In some cases, the reactive upward force exerted by the brace increases with the downward velocity of the trailer bed. The reactive force can be created by one or more pressure relief valves, hydraulic fluid passing through a flow restriction, a brake, a spring, or various combination thereof. Some embodiments of the brace include provisions for accommodating horizontal movement of the rear impact guard.

An apparatus for releasing a parking state of a shift-by-wire shifting device may include a housing fixed to a vehicle body, a driving screw rotatably coupled to the housing and threaded, a slider engaged to the driving screw and slidable along the driving screw, and a cable connected to the slider and transmitting a sliding motion of the slider to a transmission.

A socket for a camera module includes an insulative terminal assembly housing that supports a plurality of conductive terminals. The housing serves as the bottom of a socket and it is surrounded with a conductive metal shell that defines a cavity which receives a camera module. The shell has one or more elastic arms that extend into contact with the housing. The shell is movable on the housing, and the housing has one or more projections that serve as stops for the elastic arms to limit the vertical movement of the shell with respect to the housing. This vertical movement permits the shell to move relative to the housing and thereby compensate for warping and the like which may occur on circuit boards to which the socket is mounted.

For use in closing a cylindrical passageway through a working member in which the passageway is defined in part by a reduced diameter internal circumferential sealing surface and an internal locking groove, a completion plug having a plug body with a cylindrical external surface receivable within the cylindrical passageway of the working member and having an external circumferential sealing surface dimensioned to radially compressibly engage the working member internal circumferential sealing surface. The plug body has on its cylindrical surface an external locking groove. A locking ring is received in the working member internal locking groove and simultaneously in the plug body external locking groove and serves to lock the plug body within the working member.

A hanger assembly for use in a vertical production tree that includes an annular piping spool member having a side opening, and a hanger having an outer surface profiled to selectively land in the piping spool member and a side opening registered with the side opening of the piping spool member. The hanger assembly also includes a vertical penetrator having an end selectively connected to a submersible device and an opposing end inserted into the hanger, and that is in communication with the side openings.

Disclosed is an electromotive sunvisor assembly of a vehicle and a method thereof in which a visor body is automatically movable to the outside of an overhead storage room and can be pivoted at a moving shielding site. The electromotive sunvisor assembly of a vehicle comprises an upper guide bar and a lower guide bar. An upper driving member is glidingly disposed at the upper guide bar. A lower driving member is glidingly disposed at the lower guide bar. A rotary shaft is extended from the lower driving member in a lateral direction. A mounting bar is rotatably disposed at the rotary shaft and a visor body is fixed thereto. A rotational operation slat is formed protrudently from the mounting bar. A link is axially connected to one side of the upper driving member and the other end thereof is axially connected to the rotational operation slat.

Cable Support Systems for supporting an object at a desired distance below an overhead beam or other overhead structure are provided. Novel clamps for clamping to the overhead structure are fitted to support cables that encircle objects to be supported by the cable support systems. The novel clamps have internal methods to support the cables. The cables are then encircled around the objects and fixed relative to the clamp. The distances between the object and the clamps may be precisely controlled.

An adjustable plant cage comprises an elongate rod having opposite first and second ends. The first end is for insertion into a ground surface with the rod extending upwardly. A plurality of wheels are provided. Each wheel comprises a hub slidably received on the elongate rod, a ring, and spokes connecting the ring to the hub. A plurality of annular flexible support elements are each positioned at a select longitudinal position in the elongate rod to support an associated one of the wheels.

An axle / suspension system for heavy-duty vehicles having a frame and at least one suspension assembly operatively connected to the frame, the axle / suspension system including a mechanical stop having a plurality of links and a first end and a second end, the second end rigidly attached to the suspension assembly and the first end rigidly attached to the vehicle frame, wherein the first end and the second end control a distance between the first end and the second end, and control the plurality of links to attain a movement tolerance range of said mechanical stop from about 0.0 inches to about 2.0 inches.

A cup holder includes a case main body defining a housing chamber; a lid member rotatably attached to the case main body between a closed position closing the opening portion and an open position opening the opening portion; a cup retaining member; and a parallel link mechanism connecting the case main body and the cup retaining member. A connecting mechanism connects the lid member and the cup retaining member so as to interconnect together so that the cup retaining member ascends to the ascent position from a descent position, and the cup retaining member descends from the ascent position to the descent position. Stopper abutting portions are provided in the cup retaining member and the lid member to control a downward movement of the cup retaining member.

An apparatus for transporting a sensor having a sensing surface at an operational distance from a target surface is disclosed. The apparatus includes an upper frame and spaced apart parallel front and rear struts. The upper ends of the struts are connected to the upper frame. The lower ends of the struts are connected to the sensor. The front and rear struts pivot about the upper frame to move the sensor in response to an obstacle on the target surface, The sensor pivots about the lower ends of the front and rear struts to maintain the sensing surface in substantially parallel orientation to the target surface. The angle between the sensing surface and the front and rear struts is less than 90°.

An apparatus for releasing a parking state of a shift-by-wire shifting device may include a housing fixed to a vehicle body, a driving screw rotatably coupled to the housing and threaded, a slider engaged to the driving screw and slidable along the driving screw, and a cable connected to the slider and transmitting a sliding motion of the slider to a transmission.

Disclosed are liquid dispensing devices suitable for use to dispense liquid from a container. They have a conventional sprayer associated with a flexible down tube. The down tube has an essentially rigid upper section linked to the sprayer, an essentially rigid lower section suitable to extend into the container, and an intermediate flexible section. An essentially rigid member (e.g. a sleeve) is mounted on / to the down tube so as to move between a first position in which it covers the flexible section so as to restrict pivoting of the lower section relative to the upper section, to a second position in which it permits the lower section to pivot relative to the upper section. As the down tube is being inserted in the container a flange on the sleeve is held by the container lip so that the sleeve is caused to move between the two positions. The down tube structure is thus rigid during assembly of the tube with the container, but automatically becomes flexible thereafter. Methods of assembly are also disclosed using these structures.
