Abstract

Claims (29)

1. A trailer tongue assembly comprising:

a first section having an outside face and a hollow tubular first end with a cross-sectional configuration;

a second section having an outside face and a hollow tubular second end with a cross-sectional configuration; and

a hinge having a fixed section having an outside face and a first attachment flange with a cross-sectional configuration corresponding to said cross-sectional configuration of said first end, a rotatable section having a second attachment flange with a cross-sectional configuration corresponding to said cross-sectional configuration of said second end, and a pivot member rotatably connecting said fixed and rotatable sections, wherein said fixed and rotatable sections are each fabricated from an essentially unitary solid cast material and said first attachment flange is received into said hollow tubular first end and fixably attached thereto and said second attachment flange is received into said hollow tubular second end and fixably attached thereto such that said outside faces of said first, fixed and second sections smoothly transition between one another.

2. The trailer tongue assembly of claim 1 , wherein said fixed section has a rotation stop engaging said rotatable section when said rotatable section is rotationally displaced about said pivot member to a maximum rotation angle.

3. The trailer tongue assembly of claim 1 , wherein said fixed section has a top side and a bottom side, said top side being substantially thicker than said bottom side, thereby increasing the load-bearing capability of said top side relative to said bottom side.

4. The trailer tongue assembly of claim 3 , wherein said pivot member has an enlarged head and said top side has an indent sized in correspondence with said enlarged head to receive said enlarged head therein such that said enlarged head is essentially flush with said outside face of said fixed section.

5. The trailer tongue assembly of claim 1 , wherein said rotatable section has an enclosed pivot guide to receive and enclose said pivot member within said pivot guide.

6. The trailer tongue assembly of claim 1 , wherein said cross-sectional configuration of said first attachment flange corresponds to said cross-sectional configuration of said second attachment flange.

7. The trailer tongue assembly of claim 1 , wherein said first section is attached to a trailer front.

8. The trailer tongue assembly of claim 1 , wherein said second section is attached to a coupler.

9. The trailer tongue assembly of claim 1 , wherein said first section is attached to a coupler.

10. The trailer tongue assembly of claim 1 , wherein said second section is attached to trailer front.

11. A trailer tongue assembly comprising:

a first section having a first end with a cross-sectional configuration;

a second section having a second end with a cross-sectional configuration; and

a hinge having a fixed section having a first attachment flange with a cross-sectional configuration corresponding to said cross-sectional configuration of said first end, a rotatable section having a second attachment flange with a cross-sectional configuration corresponding to said cross-sectional configuration of said second end, and a pivot member rotatably connecting said fixed and rotatable sections, wherein said first attachment flange is fixably attached to said first end and said second attachment flange is fixably attached to said second end.

12. The trailer tongue assembly of claim 11 , wherein said fixed and rotatable sections are each fabricated from an essentially unitary solid cast material.

13. The trailer tongue assembly of claim 11 , wherein said fixed section has a top side and a bottom side, said top side being substantially thicker than said bottom side, thereby increasing the load-bearing capability of said top side relative to said bottom side.

14. The trailer tongue assembly of claim 11 , wherein said rotatable section has an enclosed pivot guide to receive and enclose said pivot member within said pivot guide.

15. The trailer tongue assembly of claim 11 , wherein said cross-sectional configuration of said first attachment flange corresponds to said cross-sectional configuration of said second attachment flange.

16. The trailer tongue assembly of claim 11 , wherein said first section is attached to a trailer front.

17. The trailer tongue assembly of claim 11 , wherein said second section is attached to a coupler.

18. The trailer tongue assembly of claim 11 , wherein said first section has an outside face, said second section has an outside face and said fixed section has an outside face, further wherein said outside faces of said first, fixed and second sections smoothly transition between one another.

19. The trailer tongue assembly of claim 11 , wherein said fixed section has a rotation stop engaging said rotatable section when said rotatable section is rotationally displaced about said pivot member to a maximum rotation angle.

20. A trailer tongue assembly comprising:

a first section having an outside face and a hollow tubular first end with a cross-sectional configuration;

a second section having an outside face and a hollow tubular second end with a cross-sectional configuration; and

a hinge having a fixed section having an outside face and a first attachment flange with a cross-sectional configuration corresponding to said cross-sectional configuration of said first end, a rotatable section having a second attachment flange with a cross-sectional configuration corresponding to said cross-sectional configuration of said second end, and a pivot member rotatably connecting said fixed and rotatable sections, wherein said first attachment flange is received into said hollow tubular first end and fixably attached thereto and said second attachment flange is received into said hollow tubular second end and fixably attached thereto such that said outside faces of said first, fixed and second sections smoothly transition between one another.
