Toy race car and track

Abstract

A toy race car track can be expanded to an unlimited number of lanes via interlocking side-by-side tracks. The toy race car track may be extended in length by adding additional track segments end-to-end. The tracks of the present invention may be useful for racing a toy race car with four wheels and a compartment for a marble in a central region of the car. With a marble installed in the car, all four wheels and the marble may roll at the same time as the car is moved. The car may be rolled on a surface or raced on the track. In some embodiments, the car may include lights that may flash as the car is moved.

1 . A race car track comprising:
 at least one track segment, each track segment including:
 a track bed; 
 a first side wall extending from a first track bed side; 
 a second side wall extending from a second, opposite track bed side; 
 a rail disposed along at least a portion of a first track segment side, the rail extending away from the track bed; and 
 a groove disposed along at least a portion of a second, opposite track segment side, the groove extending away from the track bed, and the groove adapted to receive and retain the rail. 
   
     
     
         2 . The race car track of  claim 1 , further comprising a longitudinal channel disposed on a bottom side of the track bed. 
     
     
         3 . The race car track of  claim 2 , further comprising a joining member adapted to join a first longitudinal channel of a first track segment with a second longitudinal channel of a second track segment. 
     
     
         4 . The race car track of  claim 3 , wherein the joining member frictionally fits into the first longitudinal channel and the second longitudinal. 
     
     
         5 . The race car track of  claim 1 , comprising at least two track segments disposed side-by-side, with the rail of one track segment inserted into the groove of a second track segment. 
     
     
         6 . The race car track of  claim 1 , wherein the track bed is adapted to receive a race car between its side walls, the race car comprising:
 a race car body;   at least two wheels disposed to rotate relative to the race car body and carry the race car body thereupon; and   a compartment in a central region of the race car body, the compartment adapted to fit a marble therewithin, wherein   when the marble is installed in the compartment and the race car is moved along the race car track, both the wheels and the marble roll.   
     
     
         7 . The race car track of  claim 6 , wherein, when the marble is installed in the compartment and the race car is moved along the race car track, the wheels and the marble roll simultaneously. 
     
     
         8 . A race car track comprising:
 at least one track segment, each track segment including:
 a track bed; 
 a first side wall extending from a first track bed side; 
 a second side wall extending from a second, opposite track bed side; 
 a rail disposed along at least a portion of a first track segment side, the rail extending away from the track bed; 
 a groove disposed along at least a portion of a second, opposite track segment side, the groove extending away from the track bed, and the groove adapted to receive and retain the rail; 
 a longitudinal channel disposed on a bottom side of the track bed; and 
 a joining member adapted to join a first longitudinal channel of a first track segment with a second longitudinal channel of a second track segment. 
   
     
     
         9 . The race car track of  claim 8 , comprising at least two track segments disposed side-by-side, with the rail of one track segment inserted into the groove of a second track segment. 
     
     
         10 . A kit comprising:
 a toy race car comprising:
 a car body; 
 four wheels disposed to rotate relative to the car body and carry the car body thereupon; 
 a compartment in a central region of the car body; and 
 a marble adapted to fit inside the compartment; and 
   race car track comprising at least one track segment, each track segment including:
 a track bed; 
 a first side wall extending from a first track bed side; 
 a second side wall extending from a second, opposite track bed side; 
 a rail disposed along at least a portion of a first track segment side, the rail extending away from the track bed; and 
 a groove disposed along at least a portion of a second, opposite track segment side, the groove extending away from the track bed, and the groove adapted to receive and retain the rail.
