US Patent:

7237439, Jul 3, 2007

Filed:

Feb 23, 2006

Appl. No.:

11/361637

Inventors:

Robert B. Rutherford - Folsom CA, US
Mike Levenson - Pembroke MA, US

International Classification:

G01L 7/04
G01M 17/02

US Classification:

73732, 73146, 731463, 731468

Abstract:

A gauge is provided for monitoring pressure of air or other gases within a tire or other gas containing chamber. A gauge includes a receiver attachable to a valve stem of the tire. A valve core is also provided on the gauge through which fill air can be directed. In this way, the gauge does not need to be removed during filling of the tire with air. A pathway extends from the valve core to the receiver within the gauge. A pressure sensor, such as a Bourdon tube, is coupled to this pathway and monitors pressure within the tire. A sensor protector is located within the path and adjacent the Bourdon tube or other pressure sensor to protect the Bourdon tube or other pressure sensor from over-pressure air or other gases that could damage the Bourdon tube or other pressure sensor.

A pathway extends from the valve core to the receiver within the gauge. A pressure sensor, such as a Bourdon tube, is coupled to this pathway and monitors pressure within the tire. A lower body of the gauge includes a latching element which can be manually actuated to temporarily mount the gauge to the valve stem. The latching element can be in the form of levers which rotate and act as a toggle to engage the valve stem and secure the gauge to the valve stem.

Appl. No.:

11/413694

Inventors:

Robert B. Rutherford - Folsom CA, US
Mike Levenson - Pembroke MA, US

International Classification:

B60C 23/02

US Classification:

731465, 340447

Abstract:

A tire pressure gauge is provided mountable to a valve stem of a tire/wheel combination or to a rim of a wheel. The tire pressure gauge includes both a proximal display viewable by an individual adjacent the tire/wheel combination and a remote indicator of tire pressure status. This remote indicator can be in the form of a warning light or in the form of a remote display with a receiver/antenna communicating with a transmitter coupled to a pressure transducer which monitors tire pressure. Most preferably, both the warning light and remote display are provided together. A valve core is associated with the tire pressure sensor for ease in adding air to the tire when needed. The pressure transducer and warning light and/or transmitter are contained together within a transmission module preferably removably coupleable to a gauge including the tire pressure sensor and the proximal display.

Inventors:

Mike Levenson - Pembroke MA, US

International Classification:

G01L 7/04

US Classification:

73732, 73146

Abstract:

A pressure gauge is provided for monitoring pressure within a reservoir, such as air within a vehicle tire. The gauge is particularly configured to allow it to remain upon a valve stem of the tire even when the tire is in operation. A receiver of the gauge can be coupled to the valve stem. A valve core is preferably provided through which air can pass from a compressed air source, so that the tire can be filled without removing the gauge. A Bourdon tube is located within a sensor chamber and measures pressure within the reservoir. A shroud or other support surface is located adjacent a central opening of the Bourdon tube so that the Bourdon tube is supported sufficiently to avoid damage from forces including centrifugal forces encountered when the tire is spinning and the gauge is mounted on the valve stem of the tire.
