Tire air pressure warning device for wheeled vehicles

摘要

A tire air pressure warning device for dual tires mounted on a common hub of a vehicle comprises a housing mounted on a hub component and having first and second pressure sensors connected in flow communication with a corresponding one of the vehicle tires. A first indicator is pivotally mounted on the housing for displacement between stored and actuated positions, and a second indicator is mounted on the first indicator for displacement therewith and for pivotal displacement relative thereto in response to displacement of the first indicator from the stored to the actuated position thereof. The first indicator is released for displacement from the stored to the actuated position thereof in response to either one of the pressure sensors sensing an unacceptable pressure in the corresponding vehicle tire, and the second indicator is displaced relative to the first indicator during the displacement of the latter to its actuated position to visually indicate which one of the two tires has the unacceptable pressure condition.
