Tire Stem Attachments Patents (Class 73/146.8)
  • Patent number: 7284419
    Abstract: A gauge is provided for monitoring pressure of air 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 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.

  • Patent number: 7281421
    Abstract: A tire pressure sensor assembly including a valve stem that can be preassembled and snap installed into a tire rim is disclosed. The tire pressure sensor assembly includes a valve stem and a printed circuit board configured with electronics for sensing tire pressure and transmitting radio frequency data related to tire pressure. The circuit board is rigidly connected to the valve stem. The valve stem and the electronics are contained in a unitary, integrated housing that is deformable to allow the valve stem portion of the assembly to be press fit into the rim opening. So installed, the assembly is securely mounted to the rim, but is no more time consuming to install than a conventional valve stem.

The assembly includes a hollow outer tube for housing a slideably disposed indicator, a sealed space above the indicator, a compression spring and a connector end fitting. An air passage runs throughout the length the indicator. Once the assembly is engaged, pressurized air feeds directly through the indicator into the sealed space, forcing the indicator down against the force of the compression spring. If the tire remains above a predetermined critical low pressure point, the indicator will remain in the down “equilibrium” position. However, if the air pressure in the tire drops below the critical pressure point the compression force of the spring will overcome the downward pressure on the indicator, and the indicator disengages or “pops” up.

The coiled spring is fitted with a piston at the upper end, and the scale rod is fitted with a stop ring and a stop sleeve around the lower end. A fixing cap is combined with the open end to prevent the components inside the hollow body from dropping out, strengthening the pressure measuring head to prolong its service life.

  • Patent number: 6959597
    Abstract: A transmitter for a tire state monitoring apparatus that is easily connected to a wheel in an optimal manner. The transmitter includes a valve stem connected to a wheel to which the tire is attached. Electric components are mounted on a circuit board to detect the state of the tire. A casing accommodates the circuit board in the tire. The casing faces toward an outer circumferential surface of the wheel. A connecting portion connects the casing to the valve stem pivotally about a line perpendicular to the axial direction of the valve stem. A pressing mechanism presses the casing toward the outer circumferential surface of the wheel to restrict pivoting of the casing.

  • Patent number: 6911903
    Abstract: A tire pressure indicator for coupling with a valve stem of a tire. The tire pressure indicator provides a first visual indication in the event that the tire pressure is below a first threshold limit and a second visual indication if the tire pressure is above a second threshold limit. The pressure indicator includes a dome shaped indicator and a dome shaped cover that is mounted over the indicator. The cover includes a plurality wedge shaped transparent viewing windows extending from near the top of the dome. The transparent viewing windows are separated by opaque portions. The indicator has a plurality of alternating wedge shaped areas of first and second colors extending from near the top of the dome to the lower peripheral edge of the indicator. The rotation of the indicator is related to the tire pressure. In one orientation of the indicator that occurs when the tire pressure is below a first predetermined limit, the first color is visible through the transparent viewing windows of the outer dome.

  • Patent number: 6911902
    Abstract: A tire inflation gas telemetry system (30) is installed inside a tire (174) mounted to a wheel (170) and is placed within a protective housing (100) having pneumatic cylinders (116, 126) with piston rods (128, 130) that are extended or retracted by tire inflation gas pressure changes. The housing is suspended by a cable (156) slung around the wheel. The cable is slack or taut depending on motion of a first piston rod, and the telemetry system is pivoted into alternate protected and operational orientations by motion of a second piston rod. When the tire is uninflated, the cable is slack, and the telemetry system is pivoted into the protected orientation. As the tire is inflated, the cable becomes taut causing the housing to be drawn tightly against the wheel, and the telemetry system is pivoted into the operational orientation.
