Abstract

This invention relates to a speed limiting device which can actually limit the speed of vehicle according to the prescribed limits of various regions. The device is controlled by an accelerator support interposed in the path of an accelerator pedal. When the prescribed speed is exceeded, indicators will be erected and visual and audio signals will be produced. Every person on the scene will be able to take precaution and thus accident may be avoided. The device is readily adjustable to suit alterations in loading conditions and the slope of the road.

Claims

1. A vehicle speed limiting and overspeed indicating system comprising an accelerator support interposed in the path of a hind-pivoted accelerator pedal, a plurality of hanging cords fastened to said accelerator support and movable in response to pivotal motion of said support as the accelerator pedal is operated, an extension spring interposed between a first and second portion of each hanging cord, a length adjusting bolt interposed between the second and third portion of each hanging cord, a plurality of load adjusting hanging rings attached at the end of the third portion of each hanging cord, a plurality of mounting plates held by a mounting bolt to a bolt holder which is rigidly attached to the vehicle, a hanging peg and bent copper terminal separated by insulating means attached to each mounting plate with one end of each mounting plate and bent copper terminal attached to the inner side of said bolt holder such that when a hanging ring is inserted on a hanging peg an electrical circuit connection is closed between said hanging peg, and hanging ring and the corresponding bent copper terminal to actuate speed limit indicating means on the vehicle both externally and internally wherein the combination of each hanging cord, relevant extension spring, hanging ring, hanging peg, and bent copper terminal defines a particular speed limit, a copper sleeve enveloping the bent end of the extension spring at the end nearest to the second portion of the hanging cord and acting as an electrical contact terminal and a copper foil attached to the extension spring and acting as a second terminal such that said terminals come in contact with each other during extension of said extension spring when the speed limit is exceeded to actuate both internal and external vehicle overspeed indicating means.

2. The vehicle speed limiting and overspeed indicating system according to claim 1, including a plurality of blue speed limit indicators and purple overspeed indicators to be installed at prominent positions both externally and internally wherein said indicators include colored fluoresent lamps, a built-in light bulb in each indicator, a plurality of electro-magnets, a plurality of wheeled soft irons and strings used for erecting the indicators and audio alarm means.

3. The vehicle speed limiting and overspeed indicating system according to claim 1 wherein at least three load adapting hanging rings are arranged in a bunch corresponding to light, medium and heavy load and each bunch is provided with an insulating cover.

4. A vehicle speed limiting and overspeed indicating system comprising a suspension type bar accelerator support interposed in the path of a front-pivoted accelerator pedal, a triangular stand used as a pair of rails for said suspension bar, a plurality of hanging cords with their lower portion divided into two forks, each being fastened to one end of said suspension bar, and movable in response to pivotal motion of said support as the accelerator pedal is operated, an extension spring interposed between a first and second portion of each hanging cord, a length adjusting bolt interposed between the second and third portion of each hanging cord, a plurality of load adapting hanging rings attached at the end of the third portion of each hanging cord, a plurality of mounting plates held by a mounting bolt to a bolt holder which is rigidly attached to the vehicle, a hanging peg and bent copper terminal separated by insulating means attached to each mounting plate with one end of each mounting plate and bent copper terminal attached to the inner side of said bolt holder such that when a hanging ring is inserted on a hanging peg an electrical circuit connection is closed between said hanging peg, said hanging ring and the corresponding bent copper terminal to actuate speed limit indicating means on the vehicle both externally and internally wherein the combination of each hanging cord, relevant extension spring, hanging ring, hanging peg and bent copper terminal defines a particular speed limit, a copper sleeve enveloping the bent end of the extension spring at the end nearest to the second portion of the hanging cord and acting as an electrical contact terminal and a copper foil attached to the extension spring and acting as a second contact terminal such that said terminals come in contact with each other during extension of said extension spring when the speed limit is exceeded to actuate both internal and external vehicle overspeed indicating means.

5. The vehicle speed limiting and overspeed indicating system according to claim 4, including a plurality of blue speed limit indicators and purple overspeed indicators to be installed at prominent positions both externally and internally wherein said indicators include colored fluoresent lamps, a built-in light bulb in each indicator, a plurality of electromagnets, a plurality of wheeled soft irons and strings used for erecting the indicators and audio alarm means.
