Abstract

Tire sensor packaging capable of being installed on a standard snap-in tire valve stem is provided. The sensor package includes an attachment member capable of being disposed in the flexible bore of a snap-in tire valve stem, and of securely engaging with the inner wall of the flexible bore. The attachment member can be an integral part of the sensor package, or it can be a separate part that acts as an expansion device (e.g., an expansion nut) when engaged with the sensor package. Preferably, the attachment member includes features, such as barbs, to provide more secure engagement with the tire valve stem. Packages according to embodiments of the invention include a package passage (e.g., a channel or a bore) to permit the flow of air past the sensor, so that the tire can be inflated or deflated. Sensors can be attached to the tire valve stem before or after the tire valve stem is installed in the wheel.

Claims

1. A package for a tire sensor, the package comprising:

a package body configured for packaging a tire sensor;

an attachment member connected to said package body and configured for attaching said package securely to a snap-in tire valve stem by disposing said attachment member in a flexible bore of said snap-in tire valve stem;

wherein said attachment member is configured to engage securely with an inner wall of said flexible bore of said snap-in tire valve stem;

wherein said snap-in tire valve stem comprises a flexible body through which said flexible bore passes and a valve assembly in communication with said flexible bore;

wherein said attachment member has a package passage capable of being in communication with said flexible bore and with an interior of a tire, whereby air can pass through said package passage and said flexible bore to inflate or deflate said tire.

2. The package of claim 1, wherein said sensor comprises a tire pressure sensor.

3. The package of claim 1, wherein said attachment member is an integral part of said package body.

4. The package of claim 1, wherein a threaded member of said package body can engage one or more corresponding threads in an aperture of said attachment member, whereby said attachment member can function as an expansion nut for more securely engaging said attachment member with said inner wall of said flexible bore of said snap-in tire valve stem.

5. The package of claim 1, wherein a protruding knob of said package body can engage with said attachment member, whereby said attachment member can function as an expansion device for more securely engaging said attachment member with said inner wall of said flexible bore of said snap-in tire valve stem.

6. The package of claim 1, wherein said package passage comprises a bore through said package or a channel formed in a side of said package.

7. The package of claim 1, wherein said attachment member comprises one or more barbs disposed to engage with said inner wall of said flexible bore of said snap-in tire valve stem.

8. A sensor and valve assembly for a tire, the assembly comprising:

a snap-in tire valve stem comprising a valve assembly disposed within a flexible body, wherein said flexible body has a flexible bore within it and in communication with said valve assembly;

a tire sensor package comprising a package body configured for packaging a tire sensor and an attachment member connected to said package body and configured for attaching said package securely to said snap-in tire valve stem by disposing said attachment member in said flexible bore of said snap-in tire valve stem;

wherein said attachment member is configured to securely engage with an inner wall of said flexible bore of said snap-in tire valve stem;

wherein said attachment member has a package passage capable of being in communication with said flexible bore and with an interior of a tire, whereby air can pass through said package passage and said flexible bore to inflate or deflate said tire.

9. The assembly of claim 8, wherein said sensor comprises a tire pressure sensor.

10. The assembly of claim 8, wherein said snap-in tire valve stem consists of said valve assembly and said flexible body, whereby said snap-in tire valve stem is a standard snap-in tire valve stem.

11. The assembly of claim 8, wherein said attachment member is an integral part of said package body.

12. The assembly of claim 8, wherein a threaded member of said package body can engage one or more corresponding threads in an aperture of said attachment member, whereby said attachment member can function as an expansion nut for more securely engaging said attachment member with said inner wall of said flexible bore of said snap-in tire valve stem.

13. The assembly of claim 8, wherein a protruding knob of said package body can engage with said attachment member, whereby said attachment member can function as an expansion device for more securely engaging said attachment member with said inner wall of said flexible bore of said snap-in tire valve stem.

14. The assembly of claim 8, wherein said package passage comprises a bore through said package or a channel formed in a side of said package.

15. The assembly of claim 8, wherein said attachment member comprises one or more barbs disposed to engage with said inner wall of said flexible bore of said snap-in tire valve stem.

16. The assembly of claim 15, wherein said one or more barbs and said tire sensor package are disposed on opposite sides of a wheel rim when said assembly is installed in a valve opening of said wheel rim.

17. A method of affixing a tire sensor to a wheel, the method comprising:

providing a snap-in tire valve stem comprising a valve assembly disposed within a flexible body, wherein said flexible body has a flexible bore within it and in communication with said valve assembly;

disposing said snap-in tire valve stem in a valve stem aperture of a wheel on which a tire can be mounted;

providing a tire sensor package comprising a package body configured for packaging a tire sensor and an attachment member connected to said package body and configured for attaching said package securely to said snap-in tire valve stem by disposing said attachment member in said flexible bore of said snap-in tire valve stem;

disposing said attachment member of said tire sensor package in said flexible bore of said snap-in tire valve stem;

wherein said attachment member has a package passage capable of being in communication with said flexible bore and with an interior of a tire, whereby air can pass through said package passage and said flexible bore to inflate or deflate said tire.

18. The method of claim 17, wherein said sensor comprises a tire pressure sensor.

19. The method of claim 17, wherein said snap-in tire valve stem consists of said valve assembly and said flexible body, whereby said snap-in tire valve stem is a standard snap-in tire valve stem.

20. The method of claim 17, wherein said disposing said attachment member of said tire sensor in said flexible bore is performed before said disposing said snap-in tire valve stem in said valve stem aperture.

21. The method of claim 17, wherein said disposing said attachment member of said tire sensor in said flexible bore is performed after said disposing said snap-in tire valve stem in said valve stem aperture.
