Pneumatic tire having accommodation tool of electronic component
View Patent ↗A pneumatic tire ( 1 ) has a tire cavity surface (HS) to which an accommodation tool ( 11 ) for accommodating an electronic component is bonded. The accommodation tool ( 11 ) includes an accommodation space ( 10 ) for accommodating an electronic component (W) therein, and includes a bonding region ( 11 Sb) which is bonded to the tire cavity surface (HS) and which is provided on one end of a back surface ( 11 S) directed to the tire cavity surface (HS). Only the bonding region ( 11 Sb) is bonded to the tire cavity surface (HS), thereby making it possible to separate a portion of a non-bonding region ( 11 Sa) on the side of the other end of the back surface ( 11 S) from the tire cavity surface (HS).
1. A pneumatic tire having a tire cavity surface to which an accommodation tool for accommodating an electronic component is bonded, wherein
the accommodation tool has an accommodation space for accommodating an electronic component therein, and comprises (1) a bonding region portion located in a bonding region which is bonded to the tire cavity surface and which is provided on one end portion of a back surface directed to the tire cavity surface and (2) a non-bonding region portion located in a non-bonding region on the other end of the back surface,
the accommodation tool is formed into a bag-like shape having an opening through which the electronic component is brought into and out from the accommodation space,
the accommodation space is formed in the non-bonding region portion, and
only the bonding region is bonded to the tire cavity surface, thereby making it possible to separate the non-bonding region portion from the tire cavity surface.
2. The pneumatic tire having the accommodation tool for accommodating the electronic component according to claim 1 , wherein the bonding region of the accommodation tool is bonded to a bead portion.
3. The pneumatic tire having the accommodation tool for accommodating the electronic component according to claim 1 , wherein the bonding region is disposed radially inward of the tire.
4. The pneumatic tire having the accommodation tool for accommodating the electronic component according to claim 1 , wherein the opening is opened such as to face the tire rotation center line.
5. The pneumatic tire having the accommodation tool for accommodating the electronic component according to claim 1 , wherein the accommodation tool comprises a rubber back sheet directed to the tire cavity surface, and a rubber front sheet superposed on the back sheet, a peripheral edge of the back sheet and a peripheral edge of the front sheet are bonded to each other, thereby forming the accommodation space.
6. The pneumatic tire having the accommodation tool for accommodating the electronic component according to claim 1 , wherein the back surface of the accommodation tool or the tire cavity surface is provided with a non-adhering layer for forming the non-bonding region.
7. The pneumatic tire having the accommodation tool for accommodating the electronic component according to claim 1 , wherein
the accommodation tool is made from a rubber back sheet located on the tire cavity surface side and a front sheet confronting the back sheet, and
the accommodation space for accommodating an electronic component is provided between the front and back sheets.
8. A pneumatic tire having a tire cavity surface to which an accommodation tool for accommodating an electronic component is bonded, wherein
the accommodation tool is made from a rubber back sheet located on the tire cavity surface side and a rubber front sheet and has an accommodation space for accommodating an electronic component between the back and front sheets,
the accommodation tool comprises (1) a bonding region portion located in a bonding region which is bonded to the tire cavity surface and which is provided on one end portion of a back surface directed to the tire cavity surface and (2) a non-bonding region portion located in a non-bonding region on the other end of the back surface,
the accommodation tool is formed into a bag-like shape having an opening through which the electronic component is brought into and out from the accommodation space, and
only the bonding region is bonded to the tire cavity surface, whereby the non-bonding region portion is separated from the tire cavity surface.
9. The pneumatic tire of claim 8 , wherein the bonding region of the accommodation tool is bonded to a bead portion.
10. The pneumatic tire of claim 8 , wherein the bonding region is disposed radially inward of the tire.
11. The pneumatic tire of claim 8 , wherein the opening is opened so as to face the tire rotation center line.
12. The pneumatic tire of claim 8 , wherein a peripheral edge of the back sheet and a peripheral edge of the front sheet are bonded to each other, thereby forming the accommodation space.
13. The pneumatic tire of claim 8 , wherein the back surface of the accommodation tool or the tire cavity surface is provided with a non-adhering layer for forming the non-bonding region.
