    Abstract: The present invention provides an extendible trailer generally consisting of three trailer sections arranged in side-by-side relation. The two outside trailer sections are connected to the central trailer section and are movable relative thereto along an axis that extends transverse to the longitudinal axis of the trailer. Two pairs of lead screws respectively interconnect the two outer trailer sections to the central trailer section, and a drive chain and cogged drive wheel assembly interconnects the two lead screws connected to each trailer section. By rotating any one the lead screws, the drive chain and cogged drive wheel assembly effectively moves the corresponding outer trailer section either toward or away from the central trailer section, thereby decreasing or increasing, respectively, the effective width of the trailer.

  • Patent number: 6698784
    Abstract: An extensible draw bar for facilitating coupling of a towed vehicle to a towing vehicle. An extension may be slidably secured to a static portion of a draw bar. A lock may be secured to the draw bar and be activated and deactivated to fix and release the extension, respectively. An extender may be activated to move the extension outwardly from the static portion. The extension may be slidable with respect to the lock while the lock is activated for certain positions of the extension relative to the lock. The extension may be positionable relative to the activated lock to automatically engage the lock to fix the position of the extension relative to the static portion.

  • Publication number: 20040032114
    Abstract: A two-wheeled trailer which can transported, when empty, in a folded position with its wheels off of the ground. Particularly useful for hunters who want to get into the back country without having to pull a trailer, it can be rapidly deployed when needed to haul game. The folding trailer is also handy for do-it-yourselfers who want to move lumber, plants, fertilizer, and the like. The trailer includes a rectangular frame which is mounted on a pair of wheels and a “T”-shaped member. Hinged to a transverse cross brace which generally bisects the rectangular frame are two arms. Disposed perpendicularly to the transverse cross brace, the arms terminate forwardly proximate with the distal ends of the “T”-shaped member to which they are pivotally connected. When the trailer is unfolded, the leg of the “T”-shaped member extends in front of the wheeled frame so as to define a tongue.

  • Patent number: 6659497
    Abstract: A mobile tri-modal trailer having a load bearing earth-traversing mode, a felled game processing mode and an equipment transport mode. When the three distinct modes are combined into the tri-modal trailer user may, if desired, transport substantial weight to a hunting location via a any convenient vehicle. Once the user has arrived at the hunting location, the tri-modal trailer is parsed into its three distinct operational functions and supporting apparatus. The felled game processing mode in concert with the equipment transporting mode's supporting apparatus i.e., the felled game processing equipment, is removed from a substantially rectangular member and a retractable A-frame is removed from the confines of its storage chamber. The retractable A-frame is erected into a selected upright position. The felled game processing equipment is attached to the retractable A-frame. After processing the felled game the parsed three modes are recombined into the tri-modal trailer.

  • Publication number: 20030214117
    Abstract: A Collapsible Trailer is disclosed. Also disclosed is a trailer that is lightweight, but durable, and includes a set of detachable deck segments that can be assembled into a deck. The trailer further includes a suspension assembly that attaches to the deck once the deck is assembled. Still further, the trailer includes at least one longitudinal member for providing a frame to partially support the assembled deck. There are versions of the trailer that are held together by cable systems, as well as versions that include a metal frame. If the trailer has a frame, there are versions having an external frame, as well as versions having a frame that is internal to the deck segments. In any case, the deck segments, when disassembled, stackable into a condensed deck stack.

  • Publication number: 20030197352
    Abstract: The trailer comprises a rectangular framework, a loading box fixedly mounted on the framework and including an horizontal platform, and a group of freely rotatable carrying wheels enabling to pull the trailer where the frames are drawn apart from one another and a retracted position where the frames are drawn in towards one another. The framework holds the frames by means of supports, that are arranged to permit a simultaneous transversal and longitudinal movement of the frames with respect to the framework when said frames are moved between a widened position and a drawn in position. The carrying wheels are respectively fixed to the two frames, and an articulation device enables to cause the frames to move by transversal and longitudinal sliding in the supports between the widened position and said drawn in position and vice versa. Longitudinal members are adapted to be juxtaposed relatively to the horizontal platform on both sides of the latter in expanded position of said trailer.
