Pressure indicating device for tube-less tire
First Claim
Patent Images
1. A device for indicating pressure of a tube-less tire of a motor vehicle, the device comprising:
- a display;
a rim upon which a tube-less tire is adapted to be fixed, with the rim including an inner surface adapted to be enclosed by the tube-less tire when fixed to the rim and including an outer surface adapted to be outside of the tube-less tire when fixed to the rim; and
an integral pipe formed in the rim, with the integral pipe and the rim being a single piece, with the integral pipe having a first end formed in the outside surface and in communication with the display and having a second end formed in the inside surface and adapted to be in communication with the tube-less tire when fixed to the rim so that the pressure of the tube-less tire is represented on the display by communicating air through the pipe.

Abstract
A pressure indicating device of a tube-less tire of a motor vehicle is on a position surrounded by the tire and faced outward for ease of reading. The device comprises an integral pipe formed in a rim being in communication between the device and the tire so that the pressure of the tire is represented on the device by communicating air through the pipe. Hence, before starting the vehicle, the driver may know the condition of each tire by visually inspecting a reading of the pressure indicating device. Once the reading of one device is abnormal, the driver can take a suitable action, i.e., replacing tire, accordingly.

4. A device for indicating pressure of a tube-less tire of a motor vehicle, the device comprising:
-
a display;
a pipe having one end in communication with the display;
a rim upon which a tube-less tire is adapted to be fixed, with the rim including an inner surface adapted to be enclosed by the tube-less tire when fixed to the rim and including an outer surface adapted to be outside of the tube-less tire when fixed to the rim; and
a hole on the rim, with the hole and the rim being a single piece, with the hole having a first end formed in the outside surface and in communication with the other end of the pipe and having a second end formed in the inside surface and adapted to be in communication with the tube-less tire when fixed to the rim so that the pressure of the tube-less tire is represented on the display by communicating air through the hole and the pipe. - View Dependent Claims (5, 6)
