  • Publication number: 20150001831
    Abstract: A tightening mechanism for a hinge assembly includes a first housing having a pair of outwardly extending spaced apart ears having aligned first bores extending through them. A second housing has a length which allows it to fit between the ears and has a pair of abutting second bores which are tapered inwardly toward one another. Tapered cylindrical bushings are configured to fit within the second bores. The tapered bushings have aligned third bores which are co-axial with one another and with the second bores. A coupling mechanism extends through the third bores and holds the second housing rotatably in the first housing. A clamping mechanism urges the bushings toward one another and inwardly into the second bores against the pin.

  • Patent number: 8286985
    Abstract: An architecture is presented that provides a double hinged tow hitch. The tow hitch is attached to a tow vehicle and allows full traction to the ground and complete control of steering. The tow hitch comprises two hinges secured together by a pin positioned at an upper portion of the hinges and a pin positioned at a lower portion of the hinges. The pins secure the hinges together and allow the hinges to flex in two positions. Additionally, the tow hitch comprises springs positioned on either side of the hinges and rubber positioned between the hinges to act as a shock absorber. When pressure is applied to the tow hitch, the springs will collapse into either the upper or lower portions of the hinges, causing the hinges to flex in two positions and pressing against the rubber between the hinges, thus acting as a suspension system for the tow hitch.

    Abstract: A trailer hitch for a vehicle includes an attachment means for attaching the hitch to a vehicle and a base suspended from the attachment means to allow limited lateral movement of the base with respect to the attachment means. A universal pivot connector, such as a hitch ball, is mounted on the base to move with the base for mating connection to a tongue of a trailer to be connected to the vehicle. The trailer tongue is biased against rotational movement with respect to the pivot connector whereby the allowed lateral movement of the suspended base and the pivot connector and the resistance to rotational movement of the trailer tongue with respect to the pivot connector combine to move the effective pivot point of the tongue on the universal pivot connector approximately to the center of the rear axle of the towing vehicle to simulate the towing movement of a fifth wheel trailer hitch.

  • Patent number: 5913528
    Abstract: A cleaning vehicle which is suitable for holding and transporting containers and devices for the commercial cleaning and disinfection of floors and other surfaces, consists of a main vehicle with wheels and a trailer with wheels and a coupling for connecting the trailer to the main vehicle. The coupling consists of at least one tow-hook and corresponding eyes in which the hook can engage. The shape of the hook and eyes is such that the coupling allows the trailer to rotate about the connecting line of the eyes of the main vehicle and/or the vertical movement of the trailer in relation to the main vehicle, but no movement of the trailer in the plane of travel in relation to the main vehicle. The wheels of the main vehicle do not lock when taking curves and are stable even on uneven surfaces. At the same time the trailer can be properly steered by the main vehicle without any undesired movements of the trailer. The improvement is also simple and economical.

  • Patent number: 5306037
    Abstract: There is disclosed a modular trailer hitch and tow bar having multiple coupling points at which the trailer may be separated from its towing vehicle. The first is a pivoting coupling on a vehicle mount unit near the horizontal axis of the towing vehicle rear wheels. The second coupling is rearwardly displaced from the first and is a sleeve and bar coupling which is normally used to separate the tow bar into a trailer connector unit and a vehicle mount unit. The third coupling is rearwardly displaced from the second and is arranged to conform to the juncture of the bifurcated arms of a conventional travel trailer tongue. The third coupling operates in conjunction with clamps engaging the tongue to form a rigid and rugged joinder of tow bar to trailer tongue arms.
