Dust shield for temperature and pressure compensating indicator
First Claim
1. A dust shield for fitting around and removably engaging an air pressure gauge apparatus fitted to a tire valve stem protruding from and in fluid communication with the interior of a tire, the pressure gauge apparatus including a tubular gauge housing substantially coaxial with the valve stem and having a gauge housing connected end secured to the valve stem and a gauge housing free end opposite the gauge housing connected end, the dust shield comprising:
- a shield tubular body having an open longitudinal shield entry end which receives and passes the gauge housing as the dust shield is slid over the pressure gauge apparatus and sealingly abuts the tire valve stem and an open longitudinal shield exposing end through which the gauge housing free end slides out of the dust shield and is exposed for viewing and which sealingly abuts the gauge housing.

a circumferential internal shield channel sized and positioned to engagingly receive the gauge flange when the dust shield is fitted over the gauge housing to releasibly lock the dust shield onto the gauge housing.
-
-
3. The dust shield of claim 1, wherein said shield tubular body has a shield middle section which bows outwardly relative to the shield entry end to be spaced outwardly from the gauge housing.
-
4. The dust shield of claim 1, wherein the pressure gauge housing free end comprises a pressure indicator display window and a pressure indicator element visible through the indicator display window displaying tire pressure.
-
5. The dust shield of claim 1, wherein the dust shield comprises a material which is flexible and resilient to permit momentary deformation of the dust shield to permit the dust shield to fit over and engage the gauge housing.
-
6. The dust shield of claim 1, wherein the dust shield comprises a material which is transparent.
-
7. The dust shield of claim 1, wherein the dust shield comprises silicone.
-
9. The dust shield of claim 1, wherein said dust shield comprises a longitudinal shield exposing end through which said housing free end slides out of the dust shield and is exposed for viewing and which sealingly engages the gauge housing.
-
8. An apparatus comprising:
-
a tire comprising a tire interior and a tire stem secured to said tire and in fluid communication with the tire interior;
an air pressure gauge apparatus fitted to said tire valve stem, said pressure gauge apparatus comprising a tubular gauge housing substantially coaxial with said valve stem and having a gauge housing connected end secured to said valve stem and a gauge housing free end opposite said gauge housing connected end;
and a dust shield comprising a shield tubular body having a longitudinal shield entry end and being fitted around said gauge housing, said shield entry end sealingly abutting said tire valve stem. - View Dependent Claims (10, 11, 12, 13, 14, 15)
a circumferential internal shield channel sized and positioned to engagingly receive the gauge flange to releasibly lock the dust shield onto the gauge housing.
