Remote control race course system

Abstract

A race course system using a plurality of low-profile straight and corner block units assembled over an existing support surface of concrete, pavement, dirt, or similar material. The block units are used to create inner and outer barriers for a race course formed therebetween in which race cars or boats may travel. The block unit includes an inner cavity, which may be selectively filled with water or sand to add weight. Each block unit is sufficiently wide so that they may be stood upon by track officials. The block units include tabs and tab receiving slots formed on opposite surfaces which enable adjacent block units to be interconnected. Each block unit may also include an optional post-receiving hole into which a post may be inserted to support safety netting for catching race cars that may jump the barrier and threaten to hit spectators. Also, each block unit may include an optional handle for easy portability.

I claim:  
     
         1 . A race track system, comprising: 
 a. a plurality of low profile, elongated straight block units, each said elongated, straight block unit being a parallelepiped with parallel, flat top and bottom faces, parallel sidewall faces, and parallel end wall faces, each said block unit having a cavity formed therein with a filling port so that a fluid may be added to said cavity to provide weight to each said block unit;    b. means to connect adjacent said straight block units together to form a continuous barrier;    c. at least one corner block unit, each said corner block unit being substantially the same height and width of said straight block units; and,    d. means to connect each said corner block unit to a side wall or to an end wall of at least one straight block unit.    
     
     
         2 . The race car track system, as recited in  claim 1 , wherein said means to connect adjacent said straight block units is at least one tab member that extends longitudinally from an end on one said straight block and a tab receiving slot formed on the adjacent said straight block unit.  
     
     
         3 . The race car track system, as recited in  claim 1 , wherein said corner block unit is one of the following groups of corner block units: a 30-degree corner block unit, a 45-degree corner block unit, a 60-degree corner block unit, a 90-degree corner block unit, and a 180-degree corner block unit.  
     
     
         4 . The race car track system, as recited in  claim 1 , wherein each said straight block unit includes a means for manually carrying said straight block unit.  
     
     
         5 . The race car track system, as recited in  claim 1 , wherein said means for manually carrying said straight block units is a recessed handle on a surface of said straight block unit.  
     
     
         6 . The remote control race car track system, as recited in  claim 1 , wherein said corner units include outward extended sloped surfaces to form an apron-like roadway structure.  
     
     
         7 . The race car track system, as recited in  claim 1 , further including a plurality of poles selectively attached to said straight block units and said corner units and a safety net that extends between said poles.  
     
     
         8 . The race car track system, as recited in  claim 1 , further including an adjustable coupling block unit.  
     
     
         9 . The race car track system, as recited in  claim 1 , wherein said straight block and corner block units are approximately four inches in height.  
     
     
         10 . The race car track system, as recited in  claim 1 , wherein said straight block units and said corner block units are approximately 13 inches in width.  
     
     
         11 . The race car track system, as recited in  claim 1 , wherein said straight block units are approximately 144 inches in length.  
     
     
         12 . A race car track system comprising 
 a. an inner barrier made of a plurality of low profile, lightweight, interlocking units;    b. an outer barrier surrounding and spaced apart from said inner barrier to form a race track therebetween, said outer barrier made of a plurality of low profile, interlocking units;    c. a safety net attached to said outer barrier to prevent airborne race cars from traveling beyond said outer barrier.    
     
     
         13 . A race car track system, as recited in  claim 11 , comprising: 
 a. a plurality of low profile, elongated straight block units, each said elongated, straight block unit being a parallelepiped with parallel top and bottom faces, parallel sidewall faces, and parallel end wall faces, each said block unit having a hollow cavity formed therein with a port so that a fluid or grain may be added to said cavity to provide weight to each said block unit;    b. at least one corner block unit, each said corner block unit having a flat bottom surface;    c. means to connect adjacent said straight block units together to form a barrier with a continuous inside surface; and,    d. means to connect each said corner block unit to the side wall or end wall of at least one straight block unit to form a turn in the race track.    
     
     
         14 . The race car track system, as recited in  claim 11 , wherein said means to connect adjacent said straight blocks is at least one tab member that extends longitudinally from an end on one said straight block and a tab receiving slot formed on the adjacent said straight block.  
     
     
         15 . The race car track system, as recited in  claim 11 , wherein said corner block unit is one of the following groups of corner block units: a 30-degree corner block unit, a 45-degree corner block unit, a 60-degree corner block unit, a 90-degree corner block unit, and a 180-degree corner block unit.  
     
     
         16 . The race car track system, as recited in  claim 11 , wherein each said straight block unit includes a means for manually carrying said straight block unit.  
     
     
         17 . The race car track system, as recited in  claim 11 , wherein said corner units include outward extended sloped surfaces to form an apron-like roadway structure.  
     
     
         18 . The race car track system, as recited in  claim 11 , further including a plurality of poles that selectively attach to said straight or corner units and a safety net that extends between said poles.  
     
     
         19 . The race car track system, as recited in  claim 11 , further including an adjustable coupling block unit.  
     
     
         20 . The race car track system, as recited in  claim 11 , wherein said straight block units and said corner block units are approximately four inches in height.
