The disclosure and prior art relates to valve stem devices and more particularly pertains to a new valve stem device for displaying air pressure in a tire.
An embodiment of the disclosure meets the needs presented above by generally comprising a valve stem that is fluidly coupled to a tire thereby facilitating the valve stem to selectively inflate and deflate the tire. A sensing unit is coupled to the valve stem and the sensing unit is visible on the valve stem. The sensing unit is in fluid communication with the valve stem to sense air pressure within the tire thereby facilitating the sensing unit to display the air pressure within the tire.
There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
The valve stem 12 has an outer wall 16 and a chamber 18. The chamber 18 extends longitudinally through the valve stem 12 and the chamber 18 is in fluid communication with an interior of the tire 14. The valve stem 12 is comprised of a fluid impermeable material such as steel or the like. A sleeve 20 is provided and the sleeve 20 is positioned around the valve stem 12. The sleeve 20 is comprised of a fluid impermeable material such as rubber or the like.
A sensing unit 22 is provided and the sensing unit 22 is coupled to the valve stem 12. The sensing unit 22 is positioned to be visible on the valve stem 12. The sensing unit 22 is in fluid communication with the valve stem 12 to sense air pressure within the tire 14. Thus, the sensing unit 22 may display the air pressure within the tire 14.
A gauge 24 is provided and the gauge 24 is coupled to the sleeve 20. Thus, the gauge 24 is visible to an individual. The gauge 24 includes indicia 26 that are printed on an outer surface of the sleeve 20. The indicia 26 comprise graduated pressure numbers 28 and hash marks 30 that are aligned with the graduate pressure numbers. The gauge 24 may be an air pressure gauge 24 or the like.
The gauge 24 includes an indicator 32 that is movably aligned with the indicia 26. The pressure sensor urges the indicator 32 to align with selected ones of the graduated pressure numbers 28 corresponding with air pressure in the tire 14. In this way the indicator 32 indicates the air pressure in the tire 14. The indicator 32 may be comprised of a luminescent material such that the indicator 32 glows in the dark thereby facilitating the indicator 32 to be visible at night. Moreover, the indicator 32 may be an analog pressure gauge 24 or the like.
In an alternative embodiment 34 as shown in
In use, the valve stem 12 is manipulated in the convention of valve stem 12s with respect to inflating and deflating the tire 14. The gauge 24 displays the air pressure in the tire 14 thereby facilitating the air pressure in the tire 14 to be continually monitored. Moreover, the air pressure in the tire 14 is monitored without the use of an extrinsic air pressure gauge 24.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, system and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
