Abstract

Apparatus for mounting an electronic tag within a tire includes a patch having a first side for mounted location against an inner liner of the tire, a second opposite side, and a socket member extending into the second side. A housing is provided having an internal tag receiving chamber defined by sidewalls and an elongate assembly bolt extends through the housing passageway and into the patch socket member to attach the housing to the patch. A remote end of the assembly bolt protrudes through the patch and carries a temperature sensor that engages the tire inner liner and transmits temperature data to electronic data transmission means within the housing. A lower portion of the housing sidewall is adapted to angle inward toward the lower housing end and a pressure measuring device is mounted within the angled sidewall portion. The housing comprises a cup and a top member, the top member covering the cap and including a dependent skirt portion engaging the patch second surface along a lower edge to seat the housing upon the patch. The cup and top components are preferably formed of a rubber matrix.

Claims

1. Apparatus for mounting an electronic tag within a tire, comprising:

a patch having a first side for mounting against an inner liner of the tire, a second side opposite the first side, and a socket member extending into the second patch side;

a housing including an internal tag receiving chamber at least partially defined by opposite sidewalls, a lower housing end adapted for location proximate the patch second side;

an elongate protruding member extendable through the housing lower end and into the patch socket member, the protruding member including a remote end extending through the patch for engagement with the tire inner liner.

2. Apparatus according to claim 1, wherein the remote end of the protruding member includes a temperature detection device for direct contacting engagement with the tire inner liner.

3. Apparatus according to claim 1, wherein the socket member is internally threaded and the protruding member is externally threaded for threaded engagement with the socket member.

4. Apparatus according to claim 1, wherein the protruding member comprises a mounting bolt having an axial passageway extending between the housing chamber and the remote end.

5. Apparatus according to claim 4, wherein the protruding member is formed of substantially thermally non-conductive material.

6. Apparatus according to claim 5, wherein the protruding member and the patch socket member are composed of substantially similar thermally non-conductive material.

7. Apparatus according to claim 1, wherein the housing sidewalls include at least one inwardly directed lower sidewall portion.

8. Apparatus according to claim 7, wherein the housing includes means for mounting a pressure sensor within the one inwardly directed housing lower sidewall portion.

9. Apparatus according to claim 8, wherein the pressure sensor is mounted substantially flush with an outward surface of the one inwardly directed housing lower sidewall portion.

10. Apparatus according to claim 9, wherein the one inwardly directed housing lower sidewall portion includes at least one air inlet aperture extending there through at a location proximate the pressure sensor and the outer surface of the one inwardly directed housing lower sidewall portion is spaced from the second side of the patch to ensure that the air inlet aperture is open to the tire cavity.

11. Apparatus according to claim 1, wherein the housing is formed of a rubber matrix.

12. Apparatus according to claim 1, wherein the housing comprises a cup member and a top member, the top member fitting over the cup member and including dependent peripheral skirt portion having a lower edge for abutting engagement against the patch second side.

13. Apparatus according to claim 12, wherein the housing cup member and top member are formed of a rubber matrix.

14. Apparatus for mounting an electronic tag within a tire, comprising:

a patch having a first side for mounting against an inner liner of the tire, a second side opposite the first side, and a socket member extending into the second patch side;

a housing including an internal tag receiving chamber at least partially defined by opposite sidewalls, a lower housing end adapted for location proximate the patch second side;

an elongate protruding member extendable through the housing lower end and into the patch socket member, the protruding member including a remote end and a temperature detection device disposed at the remote end.

15. Apparatus according to claim 14, wherein the housing is at least partially composed of a rubber matrix material.

16. Apparatus according to claim 14, wherein the protruding member remote end extends from the patch first side for engagement with the tire inner liner.

17. Apparatus according to claim 14, wherein the housing sidewalls include at least one inwardly canted lower sidewall portion and a pressure sensor mounted within the one inward directed housing lower sidewall portion.

18. Apparatus for mounting an electronic tag within a tire cavity, comprising;

a patch having a first side for mounting against an inner liner of the tire, a second side opposite the first side, and a socket member extending into the second patch side;

a housing including an internal tag receiving chamber at least partially defined by opposite sidewalls, the housing sidewalls including at least one inwardly canted lower sidewall portion and a pressure sensor mounted at a location within the one inwardly canted housing lower sidewall portion;

an elongate protruding member extendable through a lower end of the housing and into engagement with the patch socket member to connect the housing to the patch.

19. Apparatus according to claim 18, wherein the location of the pressure sensor in the one inward directed housing lower sidewall portion is spaced a distance from the second side of the patch to ensure exposure of the pressure sensor to the tire cavity.

20. Apparatus according to claim 18, wherein the protruding member includes a remote end extending through the patch and a temperature sensor disposed at the remote end of the protruding member for direct contacting engagement with the tire inner liner.
