Abstract
Abstract An electric drag strip apparatus is set forth wherein the organization includes the various features associated with the sport of "drag racing". Initially a "burn-out" area is provided wherein a plurality of troughs are positioned on either side of elongate guide slots and electrical contact strips wherein the troughs are filled with a fluid, such as water and the like, to simulate a "burn-out" area in a drag strip. A sequencing light arrangement is positioned at a starting line wherein a plurality of solenoid actuated flags indicate a winner wherein the flags are operated by means of a photo-electric eye positioned at the finish line of the drag strip. Further, a parachute docking arrangement is positioned adjacent and beyond the finish line to secure to an associated miniature car to simulate the analogous event at a drag strip.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
189 words
An electrical drag strip apparatus to provide a contest between two individuals, each racing a miniature vehicle, said apparatus comprising, an elongate support platform means including first and second tracks each adapted to accept a downwardly depending shoe secured to each of said two vehicles, and at least one electrical conductor coextensive and parallel to each of said elongate tracks, and a finish line orthogonally oriented to said first and second tracks and each electrical conductor wherein each electrical conductor terminates at said finish line and each of said first and second tracks extends beyond said finish line to a terminal end of said platform means, and a starting line orthogonally directed and formed across said first and second tracks rearwardly spaced to and parallel of said finish line with a starting indicator medially positioned of said starting line, and a pair of spaced troughs associated with each of said first and second tracks with each pair of troughs positioned exteriorly of a respective track and a respective electrical conductor wherein said troughs are positioned and spaced rearwardly of said starting line to accept a fluid within said troughs.
Claim 2
Dependent Claim
189 words
An electrical drag strip apparatus to provide a contest between two individuals, each racing a miniature vehicle, said apparatus comprising, an elongate support platform means including first and second tracks each adapted to accept a downwardly depending shoe secured to each of said two vehicles, and at least one electrical conductor coextensive and parallel to each of said elongate tracks, and a finish line orthogonally oriented to said first and second tracks and each electrical conductor wherein each electrical conductor terminates at said finish line and each of said first and second tracks extends beyond said finish line to a terminal end of said platform means, and a starting line orthogonally directed and formed across said first and second tracks rearwardly spaced to and parallel of said finish line with a starting indicator medially positioned of said starting line, and a pair of spaced troughs associated with each of said first and second tracks with each pair of troughs positioned exteriorly of a respective track and a respective electrical conductor wherein said troughs are positioned and spaced rearwardly of said starting line to accept a fluid within said troughs.
Claim 3
Dependent Claim
102 words
An electrical drag strip apparatus as set forth in claim 1 wherein a first and second pivoting flag is pivotally mounted adjacent said finish line and is positionable from a first horizontal position to a second vertical position, and a photo-electric eye and light source pair associated with each of said first and second flags whereupon one of said miniature vehicles passing between a respective photo-electric eye and light source pair energizes a solenoid associated with each of said flags to pivot a respective flag from a first horizontal position to a second vertical position to indicate passage across said finish line.
Claim 4
Dependent Claim
25 words
An electrical drag strip apparatus as set forth in claim 2 wherein said photo-electric eye and light source pairs are aligned with said finish line.
Claim 5
Dependent Claim
34 words
An electrical drag strip apparatus as set forth in claim 3 wherein a start button is associated with said starting indicator to sequentially illuminate a series of lights positioned vertically on said starting indicator.
Claim 6
Dependent Claim
47 words
An electrical drag strip apparatus as set forth in claim 4 wherein a beveled exit ramp is secured to said terminal end of said platform means to provide a gradual elevational change from an upper platform surface to a support surface supporting said electric drag strip apparatus.
Claim 7
Dependent Claim
68 words
An electrical drag strip apparatus as set forth in claim 5 wherein a parachute is positionable within a recessed compartment formed within an upper surface of said platform means with a hook associated with each parachute, and said hook is engageable within a car hook associated with each miniature vehicle whereupon a miniature vehicle passing said finish line engages said hook to couple said parachute to said vehicle.
Claim 8
Dependent Claim
31 words
An electrical drag strip apparatus as set forth in claim 6 wherein a door is pivotally mounted over said compartment to secure a parachute prior to engagement by a minature vehicle.
Claim 9
Dependent Claim
47 words
An electrical drag strip apparatus as set forth in claim 7 wherein each downwardly depending shoe associated with each miniature vehicle is mounted to an axle housing pivotally mounted to each axle of each miniature vehicle to enable pivot-ng of said miniature vehicle about a rear axle.
