Abstract

A step includes a support member extending from a vehicle frame. A first wire rod frame extends from the distal end of the support member to the vehicle frame. A second wire rod frame suspends the first frame from the vehicle frame. Furthermore, a foot board is disposed over the first frame and the support member. The step structure is of high flexibility. The step is capable of flexibly handling loads applied from the ground, and is prevented from being plastically deformed by loads applied from the ground. The first and second frames are made of wire rods. Accordingly, the step structure is made lightweight. As a consequence, the vehicle is made lightweight.

Claims

1. A step structure in a vehicle, the vehicle having an engine mounted centrally in a vehicle frame, a seat disposed above the engine, and front and rear wheels mounted on front and rear regions on opposite sides of the vehicle frame, said step structure comprising:

left and right steps, said left and right steps being disposed between the front and rear wheels and below the seat, each of said steps comprising;

a support member, said support member extending from the vehicle frame;

a first wire rod frame, said first wire rod frame extending from a distal end of said support member to the vehicle frame;

a second wire rod frame, said second wire rod frame suspending the first frame from the vehicle frame; and

a foot board, said foot board being placed over said first frame and said support member.

2. The step structure in a vehicle according to claim 1, wherein said first frame is fastened to said support member and said vehicle frame at a position higher than a lower end of the vehicle frame, and said second frame is fastened to said first frame and the vehicle frame at a position higher than the lower end of the vehicle frame.

3. The step structure in a vehicle according to claim 1, wherein said second frame is fixed to an engaging member mounted on an intermediate portion of said first frame by a bolt.

4. The step structure in a vehicle according to claim 2, wherein said second frame is fixed to an engaging member mounted on an intermediate portion of said first frame by a bolt.

5. The step structure in a vehicle according to claim 1, wherein said first frame includes a first portion extending generally parallel to a longitudinal direction of the vehicle frame and a second portion extending generally obliquely toward the vehicle frame, said first and second portions being separated from each other at an intermediate portion of said first frame by a bend.

6. The step structure in a vehicle according to claim 2, wherein said first frame includes a first portion extending generally parallel to a longitudinal direction of the vehicle frame and a second portion extending generally obliquely toward the vehicle frame, said first and second portions being separated from each other at an intermediate portion of said first frame by a bend.

7. The step structure in a vehicle according to claim 5, wherein said first and second portions are located generally in a same horizontal plane.

8. The step structure in a vehicle according to claim 6, wherein said first and second portions are located generally in a same horizontal plane.

9. The step structure in a vehicle according to claim 7, wherein said second frame extends generally obliquely upwardly from said intermediate portion to the vehicle frame.

10. The step structure in a vehicle according to claim 8, wherein said second frame extends generally obliquely upwardly from said intermediate portion to the vehicle frame.

11. A step structure in a vehicle, the vehicle having an engine mounted centrally in a vehicle frame, a seat disposed above the engine, and front and rear wheels mounted on front and rear regions on opposite sides of the vehicle frame, said step structure comprising:

left and right steps, said left and right steps being disposed between the front and rear wheels and below the seat, each of said steps comprising;

a first member, said first member extending from the vehicle frame;

a second member, said second member extending from the vehicle frame;

a wire rod frame, said wire rod frame extending from a distal end of said first member to a distal end of said second member; and

a foot board, said foot board being placed over said first member, said second member and said wire rod frame.

12. The step structure in a vehicle according to claim 11, wherein said wire rod frame is fastened to said first member and said second member at a position higher than a lower end of the vehicle frame.

13. The step structure in a vehicle according to claim 11, wherein said wire rod frame extends between said first member and said second member in a generally horizontal plane.

14. The step structure in a vehicle according to claim 12, wherein said wire rod frame extends between said first member and said second member in a generally horizontal plane.

15. The step structure in a vehicle according to claim 11, wherein said wire rod frame includes a first end engaging in a hole formed in the first member and a second, opposite end engaging in a hole formed in said second member.

16. The step structure in a vehicle according to claim 11, wherein said wire rod frame and said second member are formed from a first wire rod frame, each of said left and right steps further comprising:

a second wire rod frame, said second wire rod frame suspending the first frame from the vehicle frame.

17. The step structure in a vehicle according to claim 16, wherein said first frame is fastened to said first member and said vehicle frame at a position higher than a lower end of the vehicle frame, and said second frame is fastened to said first frame and the vehicle frame at a position higher than the lower end of the vehicle frame.

18. The step structure in a vehicle according to claim 16, wherein said second frame is fixed to an engaging member mounted on an intermediate portion of said first frame by a bolt.

19. The step structure in a vehicle according to claim 17, wherein said second frame is fixed to an engaging member mounted on an intermediate portion of said first frame by a bolt.
