Abstract

A support frame assembly configured to strengthen an upper frame portion of a frame of a vehicle, comprising a first frame member having a first end and a second end, and a second frame member having a first end and a second end, wherein both the first ends of the first and second frame members are configured to couple to a front half of the frame and the second ends of the first and second frame members are configured to couple to the front half of the frame to strengthen the upper frame portion, at least one of the first and second ends of each of the first and second frame members including at least one mechanically coupled joint configured for coupling each of the first and second frame members to the front half of the frame.

First claim

The invention claimed is:

1. A vehicle, having a front portion and a rear portion, the vehicle comprising:
a plurality of ground-engaging members; and
a frame assembly extending longitudinally between the front portion and the rear portion, the frame assembly including a front frame assembly at least partially defining the front portion, the front frame assembly including,
an upper frame portion including a longitudinally extending frame member,
a lower frame portion, and
a support frame assembly positioned at a front portion of the front frame assembly, the support frame assembly being separable from the upper frame portion and the lower frame portion, the support frame assembly including a first member, a second member positioned laterally opposite the first member, and a laterally-extending member coupled between the first member and the second member,
wherein the support frame assembly is configured to reinforce the upper frame portion, and
wherein the longitudinally extending frame member extends toward the lower frame portion, and a first end of the first member is coupled to the longitudinally extending frame member.

2. The vehicle of claim 1 , wherein the first member includes a first panel, and the second member includes a second panel.

3. The vehicle of claim 1 , wherein the first member includes a first generally vertically extending member and the second member includes a second generally vertically extending member.

4. The vehicle of claim 3 , wherein the first and second generally vertically extending members include at least one bend.

5. A vehicle having a front portion and a rear portion, the vehicle comprising:
a plurality of ground-engaging members;
a seating area including an operator seat supported by the plurality of ground-engaging members; and
a frame assembly supported by the plurality of ground engaging members and extending from the front portion to the rear portion, the frame assembly including,
an upper frame portion extending over a portion of the seating area,
a support frame including a first member in vertical relation to the frame assembly having a first end and a second end, the first end in contact with a portion of the upper frame portion, and
a lower frame portion including an upwardly extending frame member extending toward the upper frame portion, and the second end of the first member is coupled to the upwardly extending frame member,
wherein the support frame is configured to reinforce the frame assembly.

6. The vehicle of claim 5 , wherein the support frame includes a second member positioned laterally opposite the first panel.

7. The vehicle of claim 6 , wherein the support assembly further includes a laterally-extending frame member extending between the first member and the second member.

8. The vehicle of claim 7 , wherein the first member defines a first indentation to receive a first end of the laterally-extending frame member and the second member defines a second indentation to receive a second end of the laterally-extending frame member.

9. The vehicle of claim 5 , wherein the upper frame portion includes a longitudinally extending frame member extending toward the lower frame portion, and the first end of the first member is coupled to the longitudinally extending frame member.

10. The vehicle of claim 5 , wherein the second end of the first member includes a recess configured to at least partially receive a portion of the upwardly extending frame member the upwardly extending frame member via at least one recessed extension of the first panel.

11. The vehicle of claim 5 , wherein the second end of the first member is mechanically coupled to the upwardly extending frame member via a bracket.

12. The vehicle of claim 5 , wherein the support frame is removable from the frame assembly.

13. A vehicle having a front portion and a rear portion, the vehicle comprising:
a plurality of ground-engaging members;
a seating area including an operator seat supported by the plurality of ground-engaging members; and
a frame assembly supported by the plurality of ground engaging members and extending from the front portion to the rear portion, the frame assembly including,
an upper frame portion extending over a portion of the seating area, the upper frame portion including at least one longitudinally extending frame member,
a support frame including a first upstanding member, the first upstanding member including a first end coupled to the at least one longitudinally extending frame member, and
a lower frame portion including at least one upwardly extending frame member, the at least one upwardly extending frame member coupled to a second end of the first upstanding member,
wherein the support frame is configured to reinforce the frame assembly, and
wherein the support frame is removable from the frame assembly.

14. The vehicle of claim 13 , wherein the support frame includes a second upstanding member positioned laterally opposite the first upstanding member.

15. The vehicle of claim 14 , wherein the support assembly further includes a laterally-extending frame member extending between the first upstanding member and the second upstanding member.

16. The vehicle of claim 13 , wherein the first upstanding member is substantially vertical.

17. The vehicle of claim 13 , wherein the first upstanding member includes at least one bend.

18. The vehicle of claim 13 , wherein the first upstanding member is welded to at least one of the upper frame portion and the lower frame portion.

19. The vehicle of claim 13 , wherein the first upstanding member is removably coupled to at least one of the upper frame portion and the lower frame portion via a bracket.

20. The vehicle of claim 1 , wherein the support frame assembly includes at least one mechanically coupled joint between the support frame and a remainder of the frame.
