Track for model cars

## Abstract

A race track for model cars with series of pressurized air conduits. The track is designed to race at least two cars in a manner similar to a “Drag Race.” Each car has its own lane. The system of pressurized air propels the cars with bursts of air from jets. The air jets are activated by each operator using a control which is fashioned after an automobile gearshift.

## Background
This application claims the benefit of provisional application 60/390,681 filed Jun. 21, 2002.


FIELD OF THE INVENTION
This invention relates to a race track for toy model cars. More specifically, this invention relates to a drag-race style race track in which toy cars are propelled by pressurized air.
BACKGROUND OF THE INVENTION
The automobile racing game has become a favorite in both arcades and home game systems. Since its inception, it has taken on many forms. In some instances, a car race is simulated on a display screen. In others, the race cars are mechanically driven by motors. Still others are electronically operated. Continued consumer demand for the automobile racing game requires the frequent development of fresh, new approaches.
OBJECT OF THE INVENTION
It is an object of the present invention to create a fun, innovative new form of the classic automobile racing game. The embodiments of the present invention offer a setting in which toy cars are pitted against each other in drag race fashion and are operated using controls which simulate those found in a real race car.
SUMMARY OF THE INVENTION
An embodiment of the invention could be a two-lane race track for model cars. The lanes herein may be referred to as the “Left Lane” and the “Right Lane.” Each lane could be equipped with a corresponding driver's seat, a gearshift joystick, a clutch, and a series of pressurized air conduits.
The track of one embodiment of the invention could be made of plastic strips which are lined with piping on either side to prevent the car from exiting the track prematurely. The track of one embodiment could be designed to accommodate a “Drag-Race” type format in that the portion of the track in which the race takes place would be straight. Beyond that point, the track could curve around, reversing the course of each car so that the car will return to its operator. The two U-shaped lanes could be arranged side by side so that the straight portions of both lanes are preferably parallel to each other. The racing portion of each lane is preferably positioned on the inside of the platform, while the return portion of each lane follows along the outsides.
The cars of one embodiment of the invention are preferably propelled by pressurized air. This air could travel through conduits. In one embodiment, the air could travel through copper tubes. Each lane could be equipped with its own system of air conduits. The air could be administered to the cars in bursts by a series of air jets. In one embodiment of the invention, the air jets could be positioned at four preferably equidistant points above the track. They are preferably held in place by Y-shaped supports.
The bursts of pressurized air are preferably activated by the operator using the gearshift joystick. Fashioned after a real automobile gearshift, the gearshift joystick could give access to four “gears.” Each gear could be a trigger for the bursts of air. In one embodiment of the invention, the gear shift preferably has four such gears. At the precise moment each car passes under the pressurized air jets, the car's respective operator depresses the clutch with his foot and shifts to the gear corresponding to that air jet. If timed properly, the air hopefully accelerates the car in the direction of the finish line. The object of the game, then, is to time the release of the air so that the maximum force possible is exerted on the car.
In one embodiment of the invention, a pole with signal lights is preferably fixed on the end opposite the players. These lights are modeled after the starting lights of a real drag race. They indicate when the race is to begin. A timer display could be fixed to the center of one embodiment of the invention. This timer display could indicate the time taken by each car to finish the race. By this information, the winner of the race is determined.
In one embodiment of the invention, at the start of the race, two players could be seated in the bucket seats, which are preferably positioned on opposite sides of the game platform. Each player places his car at the starting point in his respective lane, below the first air jet. When the starting light indicates to go, the drivers depress their clutches and shift to “first gear,” activating the first bursts of air. When the cars pass under the second air jets, their operators shift to “Second gear” and release the second burst of compressed air, and so forth, until all jets have been activated, and subsequently, the cars finish the race. The center timer then displays the amount of time taken by each car to complete the race. The cars coast around the remainder of the track, completing a U-Turn and returning to their respective drivers.
The above-discussed embodiments of the present invention will be described further hereinbelow. When the word “invention” is used in this specification, the word “invention” includes “inventions”, that is the plural of “invention”. By stating “invention”, the Applicant does not in any way admit that the present application does not include more than one patentably and non-obviously distinct invention, and maintains that this application may include more than one patentably and non-obviously distinct invention. The Applicant hereby asserts that the disclosure of this application may include more than one invention, and, in the event that there is more than one invention, that these inventions may be patentable and non-obvious one with respect to the other.
