Abstract: This lightweight, compact, two-wheel conversion utility is specifically designed to serve as a dual-purpose device for use with a motorcycle. First, the structural design is such that a removable rail tongue hitch is fitted to the proposed invention allowing the conversion utility to be used as a carrier trailer for the motorcycle until arriving at the desired destination. There, the rail tongue hitch is detached from the frame, the motorcycle is backed between the two wheels of the utility, and is quickly and easily mounted to the rear axle and frame, thus converting the carrier trailer to a stabilizer for the motorcycle giving it a three wheel appearance. This makes it capable of increasing load capacity and less likely to overturn. The wheels are located on the outside of the conversion utility's frame and are laterally spaced apart on opposite sides of the rear wheel of the motorcycle.

Abstract: Fold flat wheeled child and cargo carriers adopting pivoting, stowable wheel axles are disclosed, of the general type which may be trailed behind other devices by a stowable and removable tow bar. The carriers may be trailed behind other devices, or are convertible to strollers or push/pull style devices. The pivoting wheel axles in various embodiments, include simple manually manipulable methods to latch each wheel in the operative or stowed flat positions, which effectively allows the device to fold to an ultra-thin profile without any wheel being detached, and the wheel axles and tires, in the stowed positions also secondarily serve to retain the various folding parts in their stowed positions within the device side elevational profile. In the child trailer and cargo carriers, the tow bar, carrier walls and associated parts all fold flat to the device frame, along with the wheel axles and tires.

Abstract: A tilt bed for a truck or a trailer, the tilt bed being able of carrying loads and providing its own ramp. The tilt bed comprises a frame, and a deck mounted on and supported by the frame, the deck having a front portion and a rear portion. The deck has rollers connected to the front portion, and the frame has tracks mounted at an angle, the tracks for guiding the deck rollers. The trailer bed further comprises a hydraulic cylinder that has a first end connected to the frame and a second end connected to the trailer bed. The hydraulic cylinder has a piston and a cylinder. As the piston moves from an extended state into a retracted state, it causes the trailer bed to move in a rearward position. At the same time, the tracks force the deck rollers in an upward motion and cause the trailer bed to tilt. Finally, the hydraulic cylinder remains parallel to the trailer deck at all times. This orientation is accomplished because the trailer deck and the hydraulic cylinder tilt around a common axis.

Abstract: The invention provides for the management and protection of excess lengths of utility cables in extendable semi-trailers. Utility cables are affixed to the front and rear sections of an extendable semi-trailer and are threaded through a protective carrier that can bend in only one direction. This directionally restrained carrier rests within a channel that shields the carrier and the cables from wear and tear and which constrains the bending of the carrier to one trans-channel turn. As the trailer is extended, the front and rear sections of the trailer and therefore the ends of the cables and carrier will move relative to one another. The cables and carrier move within the channel from a generally “U”-shaped pattern to a generally “J”-shaped pattern as the trailer moves from the retracted to the extended position.

Abstract: The present invention is related to a transport trailer with a suspended articulated platform. The device comprises a platform (1) upon which is pivotally attached a cradle formed of two interdependent arms (6) of a shaft spanning the platform transversely near the longitudinal center of the platform. The fore arms (P'2) are pivotally connected at (P2-P'2). The top of each arm is linked to a fork made up of two tie-beams (2) and a T-shaped tow bar (3). These tie-beams are pivotally connected at (P3-P'3) and (P4-P'4). The hitch device (4) is linked to the hauling vehicle, which, in moving forward, exerts a force (F). This towing force results in the raising of the platform (1) so that it pivots around (P1-P'1) and (P2-P'2). This rotation takes place around the wheel shafts (5) so that they become locked in with the aid of the wedges (10). In the upright position, as shown, the tie-beams (2) are locked against the fore arms (6) at points (S) and (S').

Abstract: The present utility relates a collapsible trailer which can be collapsed to a plane-shape when unused, and can be expanded to a basket-shape trailer with wheels and stick for conveying objects. The collapsible trailer comprises a bottom board, a primary wheel set on back side of the bottom board, a stick pivotally arranged on the trailer, a frame having two foldable boards pivoted on the bottom board and two lateral boards pivoted thereupon. The height of the lateral equals that of foldable boards in expanding state. When collapsing the trailer, the lateral boards are folded inward, and the foldable boards are folded such that the frame lies against the bottom board. The resulting configuration is fixed by a tenon provided on the trailer. Moreover, the stick is inverted to attach on the bottom board. Therefore, the trailer can be collapsed to a plane-shape. When the trail is to be used, the stick is drawn out and the tenon is unlocked.
