Abstract

The present invention relates to a shock absorbing wheel with shock absorbing properties, the wheel comprises a hub, arms and a rim. The hub comprises radial junctions between the arms and the hub, additionally the rim comprises radial junctions between the arms and the rim, wherein between the radial junctions of the hub and the rim the arms are arranged with a substantially sinusoidal shaped form. The arms further comprise a first, a second, a third and a fourth section, wherein in the first section, the arms extend from the radial junctions between the arms and the hub in a first radial direction A, and in the forth section, the arms extend from the radial junctions between the arms and the rim in a second radial direction B. The sinusoidal shaped form is arranged in the second and the third sections of the arms. The present invention is said to provide for a cost effective wheel with good shock absorbing properties.

Claims

1. A shock absorbing wheel comprising arms arranged between a hub and a rim, said hub comprises radial junctions between said arms and said hub, additionally said rim comprises radial junctions between said arms and said rim, wherein between said radial junctions of said hub and said rim said arms are arranged with a substantially sinusoidal shaped form wherein said arms comprises a first, a second, a third and a fourth section, wherein in said first section, said arms extend from said radial junctions between said arms and said hub in a first radial direction, and in said fourth section, said arms extend from said radial junctions between said arms and said rim in a second radial direction, and in that the sinusoidal shaped form is arranged in said second and said third sections of said arms, said first radial direction, said difference being different from said second radial direction determined by the length of said sinusoidal shaped form, wherein said first and second radial directions only intersect one single arm.

2. The shock absorbing wheel according to claim 1, wherein said sinusoidal shaped form in said second and third sections are substantially aligned with a radius curvature which runs parallel with said rim so that said sinusoidal shaped form is provided along said radius curvature.

3. The shock absorbing wheel according to claim 2, wherein said sinusoidal shaped arms in said second and said third sections form a full sinusoidal wave form between said first and said forth section of said arms.

4. The shock absorbing wheel according to claim 1, wherein said first and said forth sections are substantially equally long.

5. The shock absorbing wheel according to claim 1, wherein said second and said third sections are substantially equally long.

6. The shock absorbing wheel according to claim 1, wherein hub, arms and rim are manufactured in one piece of material.

7. The shock absorbing wheel according to claim 1, wherein said arms are separate parts with respect to each other.

8. The shock absorbing wheel according to claim 1, wherein said shock absorbing wheel further comprises at least one support disc arranged to the hub or the rim so as to provide for a deformation stop to said arms.

9. The shock absorbing wheel according to claim 8, wherein said shock absorbing wheel comprises two support discs.

10. The shock absorbing wheel according to claim 1, wherein said shock absorbing wheel is for use in vehicles and machines.

11. The shock absorbing wheel according to claim 1, wherein said shock absorbing wheel is for use with suitcases.

12. The shock absorbing wheel according to claim 1, wherein said shock absorbing wheel is for use with roller-skates.

13. The shock absorbing wheel according to claim 1, wherein said shock absorbing wheel is for use with lift trucks.
