Abstract

A lightweight, high-strength tow hook is provided. The tow hook includes a first member provided by an elongated strip of metal formed generally into a U-shape with a hooked end with two extending arms. The first member has a cross-sectional shape with a base and in a preferred embodiment has two extending cross-sectional legs which extend outwardly. A second member is provided forming a mounting bracket having a main body for connection to an automotive vehicle. The second member also has connected with the main body two connected lateral flanges. The flanges are connected with the first member extending arms. A third member is connected to the second member spanning the lateral flanges of the second member generally opposite the second member main body.

Claims

1. A lightweight high-strength tow hook, comprising:

2. A tow hook as described in claim 1, wherein said first member cross-sectional shape has a second extending cross-sectional leg forming a channel.

3. A tow hook as described in claim 2, wherein said first member has a filler member inserted between said first and second extending cross-sectional legs of said first member along a hook mend of said first member.

4. A tow hook as described in claim 3, wherein said filler member is illuminated.

5. A tow hook as described in claim 3, wherein said filler member is fluorescent.

6. A tow hook as described in claim 1, further including a third member bridging over a space between said first and second extending arms of said first member spaced away from said main body of said second member.

7. A tow hook as described in claim 6, wherein said third member is connected at extreme opposite ends with said flanges of said second member.

8. A tow hook as described in claim 6, wherein said third member rear edge is aligned with the rear edge of said first member.

9. A tow hook as described in claim 1, wherein said first member and second member are welded together.

10. A tow hook as described in claim 1, wherein said first and second members are connected together by fasteners.

11. A tow hook as described in claim 7, wherein said first and second members are connected on a top side and bottom side of said second member flanges.

12. A tow hook as described in claim 1, wherein said lateral flanges extend toward a hooked end of said first member beyond an extreme forward edge of said second member main body.

13. A tow hook as described in claim 1, wherein said second member main body is raised with respect to said first member.

14. A lightweight high-strength tow hook, comprising:

15. A tow hook as described in claim 14, further including a third member spaced from and spanning over said main body of said second member and being connected with said flanges of said second member.

16. A tow hook as described in claim 14, wherein said flanges extend toward a hooked end of said first member beyond an extreme forward edge of said second member main body.

17. A tow hook as described in claim 15, wherein said second member main body is raised from said second member flanges and said first member.

18. A tow hook as described in claim 14, wherein a rear extreme edge of said second member extends further rearward than a rear extreme edge of said first member.

19. A lightweight high strength tow hook, comprising:

20. A tow hook as described in claim 19, wherein said second member has an aperture which is penetrated by a fastener to connect said tow hook to said vehicle and said aperture for said fastener also penetrates through said first member.

21. A tow hook as described in claim 20, wherein said first member cross-sectional shape has a second extending cross-sectional leg forming a channel.

22. A tow hook as described in claim 21, further including a second member connected with said first member opposite said first second member and said first and second members being connected with one another.

23. A tow hook as described in claim 19, wherein the curved portion of the first member is oriented in a different plane than that of the extending arms.

24. A lightweight high strength tow hook, comprising:

25. A lightweight high-strength tow hook, comprising:

26. A fastener as described in claim 25 wherein said first member cross-sectional shape has a second extending cross-sectional leg forming a channel and a third member is connected with said first and second members via a common fastener extending through said legs.

27. A fastener as described in claim 26 wherein said second and third members are additionally connected together independent of any connection with said first member.
