Abstract

An improved wheel for a mobility apparatus designed is disclosed herein. The wheel conforms to obstacles in the ground, creating a smoother walking experience. The inner web of a tire of the wheel preferably consists of polygonal reliefs offset from each other over multiple layers in a radially symmetric pattern to create a web which naturally compresses to absorb shock from obstacles. The tire's inner core preferably consists of a hexagonal membrane that extends parallel to the axel of the tire and extends out of each side of the wheel such that it is visible.

Claims (26)

1. A light-duty equipment comprising:

a wheel comprising:

a hub and a low impact tire, wherein the low impact tire comprises an inner web comprising polygonal reliefs offset from each other over multiple layers in a radially symmetric pattern to create a web which naturally compresses to absorb shock from obstacles, wherein the low impact tire has an outer diameter (OD) ranging from 3.75 inches to 8.75 inches, an inner diameter (ID) ranging from 2.53 inches to 7.53 inches, a web inner diameter ranging from 2.53 inches to 7.53 inches, a web outer diameter ranging from 3.20 inches to 8.20 inches.

2. The light-duty equipment according to claim 1 wherein the low impact tire is composed of a polyurethane material having a Shore A hardness is less than 90 and greater than 10.

3. The light-duty equipment according to claim 1 wherein the low impact tire comprises an inner core comprising a hexagonal membrane that extends parallel to the axel of the tire and extends out of each side of the wheel such that it is visible.

4. The light-duty equipment according to claim 1 wherein the low impact tire comprises an inner core that flexes perpendicularly to the axle of the wheel which is better for absorbing impact.

5. The light-duty equipment according to claim 1 wherein the low impact tire is bonded to a rim using an adhesive.

6. The light-duty equipment according to claim 1 wherein the low impact tire is composed of a single material.

7. The light-duty equipment according to claim 1 wherein the low impact tire has increasing or varying wall-thickness in web of non-pneumatic tire, which allows for variable compression rate in the tire.

8. A stroller comprising:

a wheel comprising:

a hub and a low impact tire, wherein the low impact tire comprises an inner web comprising polygonal reliefs offset from each other over multiple layers in a radially symmetric pattern to create a web which naturally compresses to absorb shock from obstacles, wherein the low impact tire has an outer diameter (OD) ranging from 3.75 inches to 8.75 inches, an inner diameter (ID) ranging from 2.53 inches to 7.53 inches, a web inner diameter ranging from 2.53 inches to 7.53 inches, a web outer diameter ranging from 3.20 inches to 8.20 inches.

9. The stroller according to claim 8 wherein the low impact tire is composed of a polyurethane material having a Shore A hardness is less than 90 and greater than 10.

10. The stroller according to claim 8 wherein the low impact tire comprises an inner core comprising a hexagonal membrane that extends parallel to the axel of the tire and extends out of each side of the wheel such that it is visible.

11. The stroller according to claim 8 wherein the low impact tire comprises an inner core that flexes perpendicularly to the axle of the wheel which is better for absorbing impact.

12. The stroller according to claim 8 wherein the low impact tire is bonded to a rim using an adhesive.

13. The stroller according to claim 8 wherein the low impact tire is composed of a single material.

14. The stroller according to claim 8 wherein the low impact tire has increasing or varying wall-thickness in web of non-pneumatic tire, which allows for variable compression rate in the tire.

15. A stroller comprising:

a mobility assistance apparatus comprising:

a hub and a low impact tire, wherein the low impact tire comprises an inner web comprising polygonal reliefs offset from each other over multiple layers in a radially symmetric pattern to create a web which naturally compresses to absorb shock from obstacles, wherein the low impact tire has an outer diameter (OD) ranging from 3.75 inches to 8.75 inches, an inner diameter (ID) ranging from 2.53 inches to 7.53 inches, a web inner diameter ranging from 2.53 inches to 7.53 inches, a web outer diameter ranging from 3.20 inches to 8.20 inches.

16. The mobility assistance apparatus according to claim 15 wherein the low impact tire is composed of a polyurethane material having a Shore A hardness is less than 90 and greater than 10.

17. The mobility assistance apparatus according to claim 15 wherein the low impact tire comprises an inner core comprising a hexagonal membrane that extends parallel to the axel of the tire and extends out of each side of the wheel such that it is visible.

18. The mobility assistance apparatus according to claim 15 wherein the low impact tire comprises an inner core that flexes perpendicularly to the axle of the wheel which is better for absorbing impact.

19. The mobility assistance apparatus according to claim 15 wherein the low impact tire is bonded to a rim using an adhesive.

20. The mobility assistance apparatus according to claim 15 wherein the low impact tire is composed of a single material.
