Abstract

A member a support for a device includes a mass of rubber delimited by two substantially parallel opposite surfaces forming respectively a supporting surface and a surface for connection with a tire. The mass includes an opening arranged in the connecting surface delimiting a recess arranged in the mass, and the opening does not lead to outside of the connecting surface.

Claims

1. An electronic apparatus mountable on a tire, the electronic apparatus comprising:

an electronic device; and

a member for attaching the electronic device to an interior surface of a tire, the member being formed of at least a mass of rubber structured to include;

a connecting portion that connects with a tire and includes;

a peripheral connecting surface,

an upper surface, and

a peripheral end, and

a supporting portion that includes;

a first surface supporting the electronic device, and

a second surface opposite the first surface,

wherein the connecting portion extends from a peripheral portion of the second surface of the supporting portion, such that the connecting portion in combination with the supporting portion form a structure with an opening arranged in the connecting portion delimiting a recess, the recess being a non-open recess having a closed outer perimeter,

wherein the recess is delimited by and located adjacent the second surface of the supporting portion and the recess is surrounded by the connecting portion,

wherein the peripheral connecting surface;

faces a surface of the tire,

surrounds the opening of the recess proximate the surface of the tire, and

is supported by the surface of the tire,

wherein the second surface of the supporting portion faces the surface of the tire through the opening of the recess and is separated from the tire by the recess, such that the first and second surfaces of the supporting portion are interposed between the electronic device and the surface of the tire,

wherein the first surface of the supporting portion is substantially parallel to the peripheral connecting surface of the connecting portion, and

wherein the supporting portion and the connecting portion are formed integrally with each other.

2. The electronic apparatus according to claim 1, wherein an edge of the first surface of the supporting portion is aligned at least partially with an edge of the recess located adjacent the peripheral connecting surface.

3. The electronic apparatus according to claim 1, wherein an orthogonal projection of the first surface of the supporting portion onto the peripheral connecting surface of the connecting portion aligns substantially with an edge of the recess located adjacent the peripheral connecting surface.

4. The electronic apparatus according to claim 1, wherein a ratio of a depth of the recess, which extends from the second surface to the opening of the recess proximate the surface of the tire, to a distance between the first surface of the supporting portion and the peripheral connecting surface of the connecting portion is between ¼

and ½

.

5. The electronic apparatus according to claim 1, wherein a ratio of a surface area of the opening of the recess proximate the surface of the tire to a surface area of the peripheral connecting surface of the connecting portion is between 0.15 and 0.30.

6. The electronic apparatus according to claim 1, further comprising a channel arranged in the mass of rubber, wherein the channel extends from the first surface of the supporting portion to the recess located adjacent the second surface of the supporting portion.

7. The electronic apparatus according to claim 1, wherein the peripheral end of the connecting portion includes a joining portion that joins the upper surface and the peripheral connecting surface, and wherein the upper surface and the peripheral connecting surface form an angle of between 10 and 12 degrees.

8. The electronic apparatus according to claim 7, wherein the joining portion of the peripheral end is substantially a joining line at which the upper surface meets the peripheral connecting surface.

9. The electronic apparatus according to claim 7, wherein the joining portion of the peripheral end includes a ledge arranged normal to the peripheral connecting surface and having a height of between 0.1 and 0.2 mm.

10. The electronic apparatus according to claim 9, wherein the peripheral end includes a cord extending from the ledge, the cord having substantially a rectangular cross-section with a height same as that of the ledge and extending outwards from the ledge up to 1.5 mm.

11. The electronic apparatus according to claim 1, further comprising a layer of connecting rubber positioned on the surface of the tire without extending beyond the peripheral end of the connecting portion.

12. The electronic apparatus according to claim 1, wherein the member is incorporated in a tire.

13. The electronic apparatus according to claim 1, wherein a section of the mass of rubber parallel to the second surface and delimiting the recess has an annular shape.

22. The electronic apparatus according to claim 1, wherein the electronic device is supported by the supporting portion during running of the tire.

14. A tire comprising:

an interior surface;

an electronic device; and

a member for attaching the electronic device to the interior surface, the member being formed of at least a mass of rubber structured to include;

a connecting portion that connects with a tire and includes;

a peripheral connecting surface,

an upper surface, and

a peripheral end, and

a supporting portion that includes;

a first surface supporting the electronic device, and

a second surface opposite the first surface,

wherein the connecting portion extends from a peripheral portion of the second surface of the supporting portion, such that the connecting portion in combination with the supporting portion form a structure with an opening arranged in the connecting portion delimiting a recess, the recess being a non-open recess having a closed outer perimeter,

wherein the recess is delimited by and located adjacent the second surface of the supporting portion and the recess is surrounded by the connecting portion,

wherein the peripheral connecting surface;

faces a surface of the tire,

surrounds the opening of the recess proximate the surface of the tire, and

is supported by the surface of the tire,

wherein the second surface of the supporting portion faces the surface of the tire through the opening of the recess and is separated from the tire by the recess, such that the first and second surfaces of the supporting portion are interposed between the electronic device and the surface of the tire,

wherein the first surface of the supporting portion is substantially parallel to the peripheral connecting surface of the connecting portion, and

wherein the supporting portion and the connecting portion are formed integrally with each other.

15. The tire according to claim 14, wherein an edge of the first surface of the supporting portion is aligned at least partially with an edge of the recess located adjacent the peripheral connecting surface.

16. The tire according to claim 14, wherein an orthogonal projection of the first surface of the supporting portion onto the peripheral connecting surface of the connecting portion aligns substantially with an edge of the recess located adjacent the peripheral connecting surface.

17. The tire according to claim 14, wherein a ratio of a depth of the recess, which extends from the second surface to the opening of the recess proximate the surface of the tire, to a distance between the first surface of the supporting portion and the peripheral connecting surface of the connecting portion is between ¼

and ½

.

18. The tire according to claim 14, wherein a ratio of a surface area of the opening of the recess proximate the surface of the tire to a surface area of the peripheral connecting surface of the connecting portion is between 0.15 and 0.30.

19. The tire according to claim 14, wherein the member further includes a channel arranged in the mass of rubber, and wherein the channel extends from the first surface of the supporting portion to the recess located adjacent the second surface of the supporting portion.

20. The tire according to claim 14, wherein the peripheral end of the connecting portion includes a joining portion that joins the upper surface and the peripheral connecting surface, and wherein the upper surface and the peripheral connecting surface form an angle of between 10 and 12 degrees.
