Pneumatic tire
The pneumatic tire according to the present technology includes: one or more mechanical fastener members (A) disposed on the tire inner surface, which is one member of the pair of mechanical fasteners that can be separated into two members (A), (B) and that can be engaged with each other and which is secured to the tire cavity side, and the mechanical fastener members (A), (B) include a lock mechanism for locking the engagement.
1. A pneumatic tire, comprising:
one or more mechanical fastener members A disposed on a tire inner surface, each mechanical fastener member A being one member of a pair of mechanical fasteners that can be separated into two members A, B and the members A, B can be engaged with each other, and each mechanical fastener member A being secured to a tire cavity side;
the mechanical fastener members A, B including a lock mechanism for locking the engagement, wherein
of the pair of mechanical fastener members, the mechanical fastener member A that is fixed to the tire cavity side includes a base part and a cover part, wherein
the base part is embedded in the tire, the cover part is exposed on the tire inner surface, and the base part and the cover part sandwich a tire member and are fixed to each other to configure the mechanical fastener member A.
2. The pneumatic tire according to claim 1 , wherein
the base part has a small diameter projecting column and a flat plate-like base portion, and the cover part has an insert hole whose internal diameter is larger than the diameter of the projecting column; and
the small diameter projecting column that forms the base part from which the mechanical fastener member A is configured has a cylindrical column shape, a central hole of the cylindrical column shape does not pass through the cylindrical column shape, and the flat plate-like base portion has a circular flat plate shape.
3. The pneumatic tire according to claim 1 , wherein
upon the mechanical fastener member B that forms the pair with the mechanical fastener member A fixed to the tire cavity side engaging with the mechanical fastener member A fixed to the tire cavity side, the mechanical fastener member A contacts the mechanical fastener member B and presses the mechanical fastener member B, and a claw protrudes from the mechanical fastener member B to fit into a groove in a side surface of the mechanical fastener member A, so that the mechanical fastener members A, B engages with each other and configure the lock mechanism.
4. The pneumatic tire according to claim 2 , wherein
the base part and the cover part sandwich a reinforcing member, which is the tire member, and are fixed together, to configure the mechanical fastener member A.
5. The pneumatic tire according to claim 4 , wherein the reinforcing member includes a rubber coated reinforcing fiber layer.
6. The pneumatic tire according to claim 1 , wherein
the fixing strength of the mechanical fastener member A to the tire inner surface is greater than the engagement strength of the mechanical fastener members A, B, upon the mechanical fastener members A, B being engaged and locked.
7. The pneumatic tire according to claim 1 , wherein
the fixing strength of the mechanical fastener member A to the tire inner surface is from 0.5 to 100 N/mm 2 ,and the engagement strength of the mechanical fastener members A, B, upon the mechanical fastener member A, B being engaged and locked, is from 0.2 to 50 N/mm 2 .
8. The pneumatic tire according to claim 7 , wherein
the fixing strength of the mechanical fastener member A to the tire inner surface is from 1.0 to 80 N/mm 2 , and the engagement strength of the mechanical fastener members A, B upon the mechanical fastener members A, B being engaged and locked is from 0.5 to 30 N/mm 2 .
