Abstract

A wheel guard is provided for use on a material handling vehicle comprising a steering assembly, an axle extending through the steering assembly and a steer wheel mounted on the axle. The wheel guard may comprise: a front plate to be positioned adjacent to the steer wheel; an axle support coupled to and extending transverse to the front plate and comprising an axle aperture through which the vehicle axle is to be extended, the wheel guard to be rotatable about the axle; and a stop coupled to at least one of the front plate or the axle support to limit rotational movement of the wheel guard about the axle.

First claim

What is claimed is:

1. A wheel guard for use on a material handling vehicle comprising a steering assembly, an axle extending through the steering assembly and a steer wheel mounted on the axle, the wheel guard comprising:
a front plate to be positioned adjacent to the steer wheel;
an axle support coupled to and extending transverse to the front plate and comprising an axle aperture through which the vehicle axle is to be extended, the wheel guard to be rotatable about the axle; and
a stop coupled to at least one of the front plate or the axle support to limit rotational movement of the wheel guard about the axle, the stop configured to be movable toward or away from the steering assembly when the wheel guard rotates about the axle.

2. The wheel guard of claim 1 , wherein the axle support comprises a first axle support and further comprising a second axle support, the first and second axle supports being spaced apart from one another and coupled to the front plate.

3. The wheel guard of claim 2 , further comprising a back support coupled the first and second axle supports at locations on the first and second axle supports opposite to locations where the first and second axle supports are coupled to the front plate.

4. The wheel guard of claim 3 , wherein the stop comprises a first stop coupled to the back support to limit rotational movement of the wheel guard about the vehicle axle in a first direction.

5. The wheel guard of claim 4 , further comprising a second stop coupled to at least one of the front plate or the first and second axle supports and spaced from the first stop, the second stop to limit rotational movement of the wheel guard about the vehicle axle in a second direction opposite to the first direction.

6. The wheel guard of claim 5 , wherein the first stop has a first length and the second stop has a second length, and wherein a gap between the first and second stops has a length greater than the first length and less than the second length.

7. The wheel guard of claim 5 , wherein at least one of the first or the second stop comprises a removable length adapter.

8. The wheel guard of claim 1 , wherein the wheel guard is rotatable about the axle while the material handling vehicle is in motion.

9. The wheel guard of claim 1 , wherein the front plate is moveable toward or away from a surface along which the vehicle travels as the wheel guard rotates about the axle.

10. A combination comprising:
a material handling vehicle comprising:
a steering assembly;
an axle extending through the steering assembly;
a steer wheel mounted on the axle; and
a wheel guard comprising:
a front plate located adjacent to the steer wheel;
an axle support coupled to and extending transverse to the front plate and comprising an axle aperture through which the axle extends, the wheel guard being rotatable about the axle; and
a stop coupled to at least one of the front plate or the axle support to limit rotational movement of the wheel guard about the axle, the stop configured to be movable toward or away from the steering assembly when the wheel guard rotates about the axle.

11. The combination of claim 10 , wherein the axle support comprises a first axle support and further comprising a second axle support, the first and second axle supports being spaced apart from one another and coupled to the front plate.

12. The combination of claim 11 , further comprising a back support coupled to the first and second axle supports at locations on the first and second axle supports opposite to locations where the first and second axle supports are coupled to the front plate.

13. The combination of claim 12 , wherein the stop comprises a first stop coupled to the back support and limiting rotational movement of the wheel guard about the vehicle axle in a first direction.

14. The combination of claim 13 , further comprising a second stop coupled to at least one of the front plate or the first and second axle supports and spaced from the first stop, the second stop limiting rotational movement of the wheel guard about the vehicle axle in a second direction opposite to the first direction.

15. The combination of claim 14 , wherein the first stop has a first length and the second stop has a second length, and wherein a gap between the first and second stops has a length greater than the first length and less than the second length.

16. The combination of claim 14 , wherein at least one of the first or the second stop comprises a removable length adapter.

17. The combination of claim 10 , wherein the steer wheel comprises a first steer wheel and further comprising a second steer wheel, the first and second steer wheels being spaced apart on the axle.

18. The combination of claim 17 , wherein a width of the front plate is equal to or less than a width of the first and second steer wheels extending from an outer edge of the first steer wheel to an outer edge of the second steer wheel.

19. The combination of claim 10 , wherein the wheel guard is rotatable about the axle while the material handling vehicle is in motion.

20. The wheel guard of claim 10 , wherein the front plate is moveable toward or away from a surface along which the vehicle travels as the wheel guard rotates about the axle.

21. A wheel guard for use on a material handling vehicle comprising a steering assembly, an axle extending through the steering assembly and first and second steer wheels mounted on the axle, the wheel guard comprising:
a front plate to be positioned adjacent to the steer wheel; and
an axle support coupled to and extending transverse to the front plate and comprising an axle aperture through which the vehicle axle is to be extended;
wherein a width of the front plate is less than a width of the first and second steer wheels extending from an outer edge of the first steer wheel to an outer edge of the second steer wheel.
