Abstract

A fifth wheel hitch may include at least one support frame capable of engaging with a towing vehicle. The fifth wheel hitch may further include a cross-member attached to the support frame and an isolation system operatively coupled with the cross-member. The isolation system may include a beam engaged with the cross-member about a first axis, where rotation of the beam about the first axis is dampened via a cross-member isolator. The isolation system may also include a skid plate engaged with the beam about a second axis, where rotation of the skid plate about the second axis is dampened via a wing isolator.

First claim

Having thus described the invention, the following is claimed:

1. A fifth wheel hitch comprising:
a pair of support frames selectively attachable to load bed of a towing vehicle;
a cross-member positioned between the pair of support frames;
a beam rotationally attached with said cross-member;
a skid plate rotationally secured to said beam, wherein said skid plate rotates about a transverse axis;
a cross-member isolator positioned between the beam and the cross member; and
a dampener engaged with said beam, wherein said dampener dampens radial displacement of said skid plate along 360 degrees of said transverse axis while allowing free rotation of said skid plate about said transverse axis.

2. The fifth wheel hitch of claim 1 , wherein said cross-member isolator is engaged with said beam about a second axis, wherein said dampener dampens longitudinal displacement of said beam generally along said second axis.

3. The fifth wheel hitch of claim 2 further comprising a fastener extending through at least a portion of and attaching together said beam and cross-member.

4. The fifth wheel hitch of claim 3 further comprising a tube surrounding at least a portion of said fastener within said beam.

5. The fifth wheel hitch of claim 4 , wherein said tube extends through an entire width of said cross-member creating a gap into which said cross-member isolator is capable of moving.

6. The fifth wheel hitch of claim 5 , wherein said cross-member isolator dampens shock as it is compressed axially along said fastener.

7. A fifth wheel hitch comprising:
a pair of support frames selectively attachable to load bed of a towing vehicle;
a pair of mounting brackets attached with the pair of support frames;
a cross-member positioned between the pair of mounting brackets;
a beam attached with said cross-member about a first axis; and
a dampener positioned between said cross member and said beam and secured to said beam about said first axis, wherein said dampener dampens longitudinal displacement of said beam generally along said first axis.

8. The fifth wheel hitch of claim 7 further comprising a skid plate rotationally secured to said beam, wherein said skid plate rotates about a transverse axis.

9. The fifth wheel hitch of claim 8 further comprising a second dampener engaged with said beam, wherein said second dampener dampens radial displacement of said skid plate along 360 degrees of said transverse axis while allowing free rotation of said skid plate about said transverse axis.

10. The fifth wheel hitch of claim 9 , wherein the second dampener comprises rubber.

11. The fifth wheel hitch of claim 7 , wherein the dampener comprises rubber.
