Visual tire cap pressure indicator
First Claim
1. A gauge comprising:
- a. a chamber adapted to be placed in fluid communication with a pressurized device;
b. a converter operably associated with the chamber;
c. a cylindrical rotary member coupled to the converter including an open-ended bottom, a closed-ended top, a side portion extending from top to bottom and an indicator pattern on the exterior surface of the side portion; and
d. a cap covering the rotary member including an open-ended cap bottom, a closed-ended cap top, a cap side portion extending from top to bottom, a cylindrical inner surface co-axial with the exterior surface of the rotary member, and a plurality of windows having a width,where in response to a change in chamber pressure, the converter moves causing the rotary member to rotate relative to the cap windows changing an indicator state from a first state to a second state where the indicator state is viewable from the cap side.

Abstract
A pressure gauge for a pressurized device is disclosed that provides a simple, efficient and highly visual indication of pressure change from a normal condition to various abnormal conditions. The pressure gauge includes a chamber, a pressure converter located within or operably associated with the chamber, a rotary member coupled to the converter and having an indicator pattern and a cap including at least one window through which at least a portion of the indicator pattern is viewable. Once the gauge is brought into fluid communication with a pressurized device, then the cap may be rotated or adjusted to align the windows with a desired marker type placing the gauge in a normal or first indicator data. A change in pressure in the chamber will cause the gauge to undergo a change to a new or different indicator state.

18. A method comprising the steps of:
a. attaching to a pressurized device a gauge comprising; i. a chamber adapted to be placed in fluid communication with a pressurized device; ii. a converter operably associated with the chamber; iii. a cylindrical rotary member coupled to the converter including an open-ended bottom, a closed-ended top, a side portion extending from top to bottom and an indicator pattern on the exterior surface of the side portion; and iv. a cap covering the rotary member including an open-ended cap bottom, a closed-ended cap top, a cap side portion extending from top to bottom, a cylindrical inner surface co-axial with the exterior surface of the rotary member, and a plurality of windows where each window has a width, where in response to a change in chamber pressure, the converter moves causing the rotary member to rotate relative to the cap windows changing an indicator state from an initial state to a new state where the indicator state is viewable from the cap side. - View Dependent Claims (19, 20)
