Claims

[Scope of utility model registration request]

(1) A pneumatic tire made of a cylinder made of fabric or sheet and having a diameter approximately equal to the inner diameter of the bead of the tire to which it is attached, with rings having an outer diameter slightly larger than the inner diameter of the tire fixed along both edges of the cylinder. Protective equipment to prevent foreign objects from entering the interior.

(2) A protective device for preventing foreign matter from entering into a pneumatic tire according to claim 1, wherein the cylinder is a stretchable cylinder made of stretchable fabric or a stretchable sheet.

(3) A protective device for preventing foreign matter from entering a pneumatic tire according to claim 1, wherein the ring is flexible and can be elastically restored after deformation.

(4) Cut the cylinder into two along the circumferential direction near at least one end, and cut the cylinder into two along the cut edge, inside one cylinder and outside the other cylinder, respectively. A protective device for preventing foreign matter from entering a pneumatic tire according to claim 1, which is configured to have a planar fastener to be connected and to connect the cut edges in a detachable manner.

(5) A claim for utility model registration in which the ring has an angular cross-section and is shaped to fit tightly into the bead of the tire, and at least one end of the cylinder is removably connected to the ring by a plane fastener. A protective device for preventing foreign matter from entering a pneumatic tire as described in Scope 1.

(6) A protective device for preventing foreign matter from entering a pneumatic tire according to claim 2 or 3 of the utility model registration claim, in which an elastic pad is attached to the inner surface of the portion of the cylinder that is in contact with the bead of the tire. . ,
