Abstract

Two hard steel wire-made reinforcing wires and two synthetic resin wires which are harder than a soft synthetic resin pipe wall are alternately wound spirally on an inner side of the synthetic resin pipe wall while keeping predetermined intervals.

Claims

1. A cleaner hose comprising:

a synthetic resin pipe wall;

two steel wires; and

two synthetic resin wires harder than said resin pipe wall, wherein each of said steel wires and each of said two synthetic resin wires are alternately and spirally wound in an inner side of the synthetic resin pipe wall at predetermined intervals.

2. The cleaner hose according to claim 1, further comprising:

a first electric connector attached at the one end of a pipe body defined by said resin pipe wall; and

a second electric connector attached at the other end of said pipe body, in which said second electric connector is electrically connected to said second connector through said two steel wires.

3. The cleaner hose according to claim 1, wherein said steel wires and said resin wires are bonded to the inner surface of said pipe wall.

4. The cleaner hose according to claim 2, wherein said steel wires and said resin wires are bonded to the inner surface of said pipe wall.

5. The cleaner hose according to claim 1, wherein said pipe wall comprises an outer layer and an inner layer, and said steel wires and said resin wires are interposed between said inner and outer layers.

6. The cleaner hose according to claim 1, wherein each of said steel wires is coated with a synthetic resin.

7. The cleaner hose according to claim 2, wherein each of said steel wires is coated with a synthetic resin.

8. The cleaner hose according to claim 3, wherein each of said steel wires is coated with a synthetic resin.

9. The cleaner hose according to claim 4, wherein each of said steel wires is coated with a synthetic resin.

10. The cleaner hose according to claim 5, wherein each of said steel wires is coated with a synthetic resin.

11. The cleaner hose according to claim 1, wherein each of said resin wires is a hollow shape.

12. The cleaner hose according to claim 2, wherein each of said resin wires is a hollow shape.

13. The cleaner hose according to claim 3, wherein each of said resin wires is a hollow shape.

14. The cleaner hose according to claim 4, wherein each of said resin wires is a hollow shape.

15. The cleaner hose according to claim 5, wherein each of said resin wires is a hollow shape.

16. The cleaner hose as recited in claim 1, wherein two synthetic resin wires comprised of a semi-hard PVC.

17. The cleaner hose as recited in claim 6, wherein the synthetic resin is a semi-hard PVC.

18. The cleaner hose as recited in claim 7, wherein the synthetic resin is a semi-hard PVC.

19. The cleaner hose as recited in claim 8, wherein the synthetic resin is a semi-hard PVC.

20. The cleaner hose as recited in claim 9, wherein the synthetic resin is a semi-hard PVC.

21. The cleaner hose as recited in claim 10, wherein the synthetic resin is a semi-hard PVC.
