Abstract

The invention relates to a device for fastening an electronic monitoring module onto a tire comprising a patch (12) of rubber mix, an upper surface of which bears at least one rigid insert (18, 19) having a threaded recess (181, 191) intended to cooperate with a screw (14, 15) and a lug (131, 132) on a casing (13) bearing the electronic monitoring module.

Claims

1. A device for fastening an electronic monitoring module to a tire, said fastening device comprising a patch formed of a rubber mix and having an upper surface intended to be in contact with air, at least one rigid insert carried on the patch and having a threaded recess for engagement with a screw and a lug borne by a casing bearing the electronic monitoring module, wherein, the insert has a frustoconical shape and is disposed in the patch with the base of lesser diameter at the upper surface.

2. A device according to claim 1, in which an outer shape of the patch follows the frustoconical shape of the insert to define a protrusion.

3. A device according to of claim 1, wherein the insert is made of bronze.

4. A device according to claim 1, in which the insert is made of nylon.

5. A device according to claim 1, in which the insert is made of brass.

6. A device according to claim 1, wherein, the patch has two inserts, the outer form of the patch following the frustoconical shape of the two inserts to define two spaced protrusions, wherein the patch constitutes a shock mount with respect to the casing.

7. A device according to claim 1, further comprising a reinforcing fabric disposed in the patch.

8. A device according to claim 7, in which the reinforcing fabric is formed of rayon.

9. A device according to claim 1, in which the upper surface of the patch is covered with a gas-impermeable coating.

10. A device according to claim 9, in which the gas-impermeable coating is formed by a butyl rubber.

11. A device for fastening an electronic monitoring module to a tire, comprising:

a casing for containing electronic monitoring components having lugs extending laterally therefrom;

a patch of rubber mix having an upper surface for contact with air and a lower surface for bonding to a tire surface;

two rigid inserts carried by the patch and each having a threaded recess opening on the upper surface; and

,

a threaded fastener for insertion through the lug on the casing and engageable with the at least one threaded recess to secure the casing to the patch.

12. A device according to claim 11, wherein the patch is shaped with two upwardly extending, spaced protuberances, each protuberance carrying one insert.

13. A device according to claim 11, in which the inserts have a frustoconical shape and are disposed in the patch with the base of smaller diameter upwardly facing.

14. A device according to claim 11, wherein the inserts are made of bronze.

15. A device according to claim 11, wherein the inserts are made of nylon.

16. A device according to claim 11, wherein the inserts are made of brass.

17. A device according to claim 11, further comprising a reinforcing fabric disposed in the patch.

18. A device according to claim 17, wherein the reinforcing fabric is formed of rayon.

19. A device according to claim 12, in which the upper surface of the patch is covered with a gas-impermeable coating.

20. A device according to claim 19, in which the gas-impermeable coating is formed by a butyl rubber.
