ABSTRACT:
A low tire warning system comprising a warning box (11) to attach to or set on the dashboard (12) of any operator controlled vehicle. The warning box (11) has within, a lighted on/off switch (13), a red warning light (14), and buzzer (15) to warn said operator of a low or flat tire on that vehicle or any vehicle/s in tow. The system is powered by plugging it into the cigarette lighter socket (16) found on the dashboard (12) of most vehicles or it may be hard-wired to a power source and grounded. The warning box (11) is connected to sensor switches (25) mounted perpendicular to the roadway (28) on the axle (23) or axles of said vehicles close to the pneumatic tires (24). The sensor switch (25) is comprised of an electrical spring actuator rod (27) running through a rubber insulator (26) inside a metallic cylinder (32). This electrical spring actuator rod (27) hangs freely in the bottom portion of the metallic cylinder (32) and extends beyond the bottom end thereof to just above the roadway (28). The conductor wire (21) from the warning box (11) is attached to the top of the electrical spring actuator rod (27). Upon the event of a low tire, the electrical spring actuator rod (27) touches the roadway (28) bending it over to make contact with the bottom of the metallic cylinder (32) wall thereby completing the electrical circuit that sets off the warning light (14) and buzzer (15).
