Abstract: A dump truck system comprising a vehicle, a trailer assembly on which is mounted a trailer bed, a hitch assembly for connecting the trailer assembly to the vehicle, and trailer dump assembly for pivoting the trailer bed relative to the trailer about a dump axis. Optionally, the dump truck system may comprise a tilt assembly for tilting the trailer bed relative to the trailer assembly about a tilt axis, where the tilt axis is substantially perpendicular to the dump axis. The trailer assembly optionally comprises a trailer frame assembly, a tube member pivotally connected to the trailer frame assembly, and a suspension assembly arranged between the tube assembly and the trailer frame assembly to resiliently oppose transmission of shocks from the trailer frame assembly to the vehicle. The trailer assembly optionally comprises a trailer frame assembly, a support tube member attached to the trailer frame assembly, a slide tube member that extends through and is supported by the support tube member.

Abstract: An archery sight for a bow comprises an integral pin plate, pin guard and windage adjustment structure. In a preferred embodiment, the pin plate is configured to maintain the sight pins in substantially parallel arrangement relative to one another. In another preferred embodiment, the pin plate defines a plurality of elongate apertures, each for securing a sight pin to the pin plate. Accordingly, the sight pins can pivot relative to the pin plate allowing for closer arrangement of the tips of the sight pins than would otherwise be allowable if the pins were maintained in a parallel relationship. In yet another preferred embodiment, the archery sight is comprised of an integrated pin plate, pin guard, and adjustable windage mechanism. In still another preferred embodiment, the archery sight comprises at least one two-headed sight pin preferably having sight heads of different widths.

Abstract: A removable inflatable support and comfort bag that is designed to be inserted into a specially formed pocket built into the lumbar region of a backpack waist belt. The partially or fully inflated bag helps transfer the weight of the load of the backpack in the lumbar region of the user's back, providing relief from fatigue. The bag is in the form of an airtight, watertight bladder that is insertable into a lumbar pocket in the waist belt of a backpack, and is connected by a hose to a hand pump which includes a release valve. The waist belt may include a pre-molded pad with grooves for channeling perspiration and moisture away from the lumbar region.

Abstract: An internal frame backpack having a large flat closable pocket along one entire side which pocket is adapted to receive a rigid contoured rectangular piece in order to provide support for said pack. The piece may be corrugated for additional strength, and is specially molded to conform to the lumbar region, shoulders, back and head of a human wearer so as to minimize interference with the free movement of the wearer's back, shoulders and head. An alternative embodiment provides contours adapted to receive the shoulder straps of the backpack to avoid their rubbing against the back of the user.
