Abstract

A wheeled vehicle including a platform portion having a mounting bracket for coupling a fifth wheel hitch to the vehicle. A pair of elongate frame members are located beneath the platform portion, and each having a lengthwise axis oriented substantially parallel to a forward direction of travel of the vehicle. A brace frame beneath the platform that is coupled between the pair of elongate frame members. The mounting bracket is secured to the brace frame and includes a stabilizer including a pair of elongate support arms joined by a cross-member. An anchor arrangement fixes the bracket relative the platform with long axes of the pair of arms transverse to the forward direction of travel.
The mounting bracket has a lower portion in abutting engagement with the platform portion of the vehicle and an upper portion configured for receiving fixed coupled engagement of a fifth wheel hitch.

Claims (25)

1. A mounting bracket for coupling a fifth wheel hitch to a bed of a wheeled vehicle and wherein the vehicle bed has a lengthwise axis oriented substantially parallel to a forward direction of travel of the vehicle and a widthwise axis oriented substantially perpendicular to the forward direction of travel of the vehicle, said mounting bracket comprising:
a stabilizer comprising a pair of elongate support arms coupled together by a cross-member that maintains respective long axes of said pair of elongate support arms in substantial parallel orientation; and an anchor arrangement that couples said mounting bracket in a vehicle bed with respective long axes of said pair of elongate support arms oriented transverse to a lengthwise axis of the vehicle bed, said mounting bracket having a lower portion configured for abutting engagement with the vehicle bed and an upper portion configured for receiving fixed coupled engagement of a fifth wheel hitch head.
2. The mounting bracket as recited in claim 1, wherein said anchor arrangement couples said mounting bracket in the vehicle bed with the respective long axes of said pair of elongate support arms oriented substantially perpendicular to the lengthwise axis of the vehicle bed.
3. The mounting bracket as recited in claim 1, wherein said respective long axes of said pair of elongate support arms are each oriented substantially perpendicular to a long axis of said cross-member.
4. The mounting bracket as recited in claim 3, wherein said mounting bracket has an H-shape top-plan view in a bed installed orientation.
5. The mounting bracket as recited in claim 4, wherein legs of said H-shaped mounting bracket comprise said pair of elongate support arms and the respective long axes of said pair of elongate support arms are oriented substantially perpendicular to the lengthwise axis of the vehicle bed in the bed installed orientation.
6. The mounting bracket as recited in claim 1, wherein said anchor arrangement further comprises a releasable fastener having an upper portion that engages said mounting bracket and a lower portion that releasably engages a brace frame located below the vehicle bed.
7. The mounting bracket as recited in claim 6, wherein said lower portion of said releasable fastener is threaded for screwed engagement with the brace frame located below the vehicle bed and said upper portion of said releasable fastener comprises a head portion that snuggly abuts said mounting bracket in a secured orientation.
8. The mounting bracket as recited in claim 7, further comprising a receiving aperture through said cross-member, said receiving aperture bounded by a receiving surface that abuttingly receives said head portion of said releasable fastener in the secured orientation.
9. The mounting bracket as recited in claim 8, wherein said receiving aperture through said cross-member is geometrically centered relative a top plan view of said mounting bracket in the bed installed orientation.
10. The mounting bracket as recited in claim 7, wherein said releasable fastener further comprises a releasable sleeve formed at a bottom distal end thereof in the secured orientation.
11. The mounting bracket as recited in claim 7, wherein said head portion of said releasable fastener further comprises a non-round exterior periphery and said mounting bracket further comprising a wrench having an opening comprising a non-round interior periphery matingly engaged with said head portion.
12. A wheeled vehicle comprising:
a platform portion including a mounting bracket for coupling a fifth wheel hitch to the vehicle;

a pair of elongate frame members beneath said platform portion, each of said elongate frame members having a lengthwise axis oriented substantially parallel to a forward direction of travel of the vehicle;
a brace frame beneath said platform portion and coupled between said pair of elongate frame members, said brace frame having a lengthwise axis oriented substantially perpendicular to the forward direction of travel of the vehicle; and said mounting bracket secured to said brace frame and comprising a stabilizer comprising a pair of elongate support arms coupled together by a cross-member that maintains respective long axes of said pair of elongate support arms in substantial parallel orientation, said mounting bracket further comprising an anchor arrangement fixing said mounting bracket relative the platform portion with respective long axes of said pair of elongate support arms oriented transverse to the forward direction of travel of the vehicle, said mounting bracket having a lower portion in abutting engagement with the platform portion of the vehicle and an upper portion configured for receiving fixed coupled engagement of a fifth wheel hitch.
13. The wheeled vehicle as recited in claim 12, wherein a predominant portion of said mounting bracket is located above said brace frame.
14. The wheeled vehicle as recited in claim 12, wherein respective end portions of said elongate support arms are each located above an elongate frame member.
15. The wheeled vehicle as recited in claim 12, wherein said anchor arrangement couples said mounting bracket on the platform portion with respective long axes of said pair of elongate support arms oriented substantially perpendicular to the lengthwise axis of the platform portion.
16. The wheeled vehicle as recited in claim 12, wherein said respective long axes of said pair of elongate support arms are each oriented substantially perpendicular to a long axis of said cross-member.
17. The wheeled vehicle as recited in claim 16, wherein said mounting bracket has an H-shape top-plan view in a platform installed configuration.
18. The wheeled vehicle as recited in claim 17, wherein legs of said H-shaped mounting bracket comprise said pair of elongate support arms and the respective long axes of said pair of elongate support arms are oriented substantially perpendicular to the lengthwise axis of the platform portion of the vehicle in the installed configuration.
19. The wheeled vehicle as recited in claim 12, wherein said anchor arrangement further comprises a releasable fastener having an upper portion that engages said mounting bracket and a lower portion that releasably engages the brace frame beneath the platform portion.
20. The wheeled vehicle as recited in claim 19, wherein said lower portion of said releasable fastener is threaded for screwed engagement with the brace frame beneath the platform portion and said upper portion of said releasable fastener comprises a head portion that snuggly abuts said mounting bracket in a secured configuration.
21. The wheeled vehicle as recited in claim 20, further comprising a receiving aperture through said cross-member, said receiving aperture bounded by a receiving surface that abuttingly receives said head portion of said releasable fastener in the secured configuration.
22. The wheeled vehicle as recited in claim 21, wherein said receiving aperture through said cross-member is geometrically centered relative a top plan view of said mounting bracket.
23. The wheeled vehicle as recited in claim 12, further comprising a bed floor fixedly mounted to said elongate frame members.
24. The wheeled vehicle as recited in claim 23, wherein distal ends of the elongate support arms are positioned substantially above said elongate frame members and a gap space is present between said bed floor and elongate frame members.
25. The wheeled vehicle as recited in claim 24, further comprising load bearing support brackets located substantially beneath said distal ends of the elongate support arms and positioned in the gap space between the bed floor and elongate frame members.
