Abstract: Overhead frame structures for a vehicle that are adjustable for modifying the overall height of the vehicles yet meet an industry-recognized standard of rollover protection for the operator of the vehicle regardless of such adjustment to the structure. In some cases, the structures are incorporated with brackets at their adjustable connection areas. The brackets have separate members for one or more of aligning and supporting adjustable members of the structure.

Abstract: Embodiments of the invention relate to providing a vibration dampening system for an overhead frame structure used with a vehicle. The system involves the provision of one or more dampening members and/or components between portions of one or more members forming the overhead frame structure. The dampening members or components are compressed when certain portions of the members are set in position. As a result, the vibration and contact normally encountered between the portions and/or interconnecting brackets is limited, and in turn, the stress normally experienced by the one or more fastener assemblies holding the portions and/or the interconnecting brackets due to such vibration is also limited.

Abstract: The invention provides an apparatus and method for providing an overhead frame structure having two side frame members each with at least one protrusion and one or more cross members coupling the side frame members through interconnection with the protrusions. Each protrusion has a corrugated configuration. Each cross member has end portions each having a wall with corrugated configuration. Each wall is adapted to engage one of the protrusions. The end portions in each cross member are adapted to receive one of the pairs of opposing protrusions therein. The cross members are coupled between the side frame members with the engagement and subsequent securing of the protrusions to the end portions of the cross members.

Abstract: The invention provides a system and a method for lifting and transporting vehicles, such as a snowmobile or other recreational vehicle. The system includes a frame member having a first rail member and attached to a vehicle, a second rail member moveable along the first rail member into a deployment position wherein it extends rearwardly of the frame, a moveable support member which can extend supportively between the second rail member and the ground, and a platform member slidable along the first and second rail members.

Abstract: A carrying rack mountable on a vehicle, such as a pickup, for carrying bulky and oversized objects. The rack is characterized by including a frame mountable to the bed of the vehicle and including a forward rack member. The frame also includes a pair of support members extending rearwardly of the front rack member, these support members including a pivotal connection carrying a rear rack section. The rear rack section is movable between a forward, folded position and a rearward, extended position for carrying large objects thereupon. The foldable nature of the rack permits easier access into the bed of the truck when the rack is not in use, while providing an aesthestically pleasing configuration, such as that of a roll bar. Optional winch means, lighting, and reflectors may also be incorporated in the unit.
