Abstract

To provide a moving device that can be used as a mobility device to transport objects and can be improved in portability. The moving device that is movable with rotation of wheels includes a body unit inflated by injection of fluid and deflated by discharge of the fluid, a support body provided on a predetermined surface of the body unit, and the wheels provided in the support body, wherein the interior of a predetermined portion of the body unit that receives a load from an object contacting the body unit is formed with a drop-stitch structure, and the drop-stitch structure after injection of the fluid has tensile forces in directions approximately perpendicular to the direction of the load applied to the predetermined portion by the object.

First claim

What is claimed is:

1. A moving device that is movable with rotation of a wheel, the device comprising:
a body unit inflated by injection of fluid and deflated by discharge of the fluid;
a support body provided on a predetermined surface of the body unit; and
the wheel provided in the support body;
the body unit having a predetermined portion receiving a load from an object contacting the body unit, the predetermined portion having an interior formed with a drop-stitch structure, the drop-stitch structure after injection of the fluid having tensile forces in directions approximately perpendicular to a direction of the load applied to the predetermined portion by the object.

2. The moving device according to claim 1 , wherein in the case where the body unit is of a motorcycle shape,
the body unit has a first section including a seat in the predetermined portion, a second section including a handle, and a connecting section between the first and second sections, and
the connecting section is recessed from side surfaces of the first section near the connecting section and from side surfaces of the second section near the connecting section to allow the second section to swivel with respect to the first section.

3. The moving device according to claim 2 , wherein
the first section has
a second connection mechanism on a bottom surface, the second connection mechanism being connectable to a first connection mechanism in the support body including the wheel, and

the second section has
a footrest at a lower portion on each side surface and
a fourth connection mechanism on a bottom surface, the fourth connection mechanism being connected to a third connection mechanism including another wheel.

4. The moving device according to claim 1 , wherein in the case where the body unit is of a wheelchair shape,
the body unit includes a seat in the predetermined portion, and
the support body is on each side surface of the body unit.

5. The moving device according to claim 1 , wherein in the case where the body unit is of a box shape, the body unit has a second connection mechanism on a bottom surface, the second connection mechanism being connectable to a first connection mechanism in the support body, the support body including a battery, a drive unit, and the wheel.

6. The moving device according to claim 1 , wherein the drop-stitch structure comprises a plurality of fibers bundled together.

7. The moving device according to claim 1 , wherein the body unit includes an inlet port for injection of the fluid.

8. The moving device according to claim 7 , wherein the inlet port is further configured to operate as a discharge port.

9. The moving device according to claim 7 , wherein the inlet port comprises a cap or valve structure.

10. The moving device according to claim 1 , wherein the body unit comprises a first section connected to the support body, a second section, and a connecting section coupling the first section and the second section.

11. The moving device according to claim 10 , wherein the connecting section is configured to allow the second section to swivel with respect to the first section.

12. The moving device according to claim 10 , wherein the second section is connected to a handle and configured to manipulate a direction of movement for the moving device.

13. The moving device according to claim 10 , wherein the first section, the second section, and the connecting section are integrally formed as a single piece of material.

14. The moving device according to claim 1 , wherein the support body is composed of one or more of metal, resin, wood, and ceramic.

15. The moving device according to claim 1 , further comprising a drive unit provided in the support body and configured to control rotation of the wheel.

16. The moving device according to claim 15 , further comprising a battery unit provided in the support body and configured to provide power to the drive unit.

17. The moving device according to claim 1 , wherein the body unit is configured to be foldable while deflated.

18. The moving device according to claim 1 , wherein the body unit comprises a recessed section configured to store one or more objects.

19. The moving device according to claim 1 , wherein the predetermined surface of the body unit comprises a connection mechanism configured to connect the body unit to the support body.

20. The moving device according to claim 19 , wherein the connection mechanism comprises a plate with a hole configured to receive a screw.
