Adjustable goalpost with audience control

Abstract

A goalpost for football games and the like has a pair of parallel uprights that may be moved toward and away from one another by a motor driven mechanism. A control system for driving the motor has an input signal based on the sound level produced by spectators at a game and/or the number of Internet messages generated by TV spectators. The spectators produce a crowd roar or Internet messages when a kick through the uprights is to occur.

Having disclosed my invention, I claim: 
     
         1 . An audience controlled adjustable goalpost assembly, comprising:
 a pair of spaced vertical uprights;   a horizontal crossbar supporting the lower ends of the uprights;   a drive system for engaging the lower ends of the uprights and adjusting their horizontal spacing from one another; and   a drive system controlled by a signal generated by the audience for a game employing the adjustable goalpost assembly for controlling the spacing between the uprights.   
     
     
         2 . The adjustable goalpost assembly of  claim 1 , wherein the audience participation signal is generated by the volume of the sound generated by the audience. 
     
     
         3 . The adjustable goalpost assembly of  claim 1 , wherein the audience control signal is generated by messages sent by the audience over the Internet. 
     
     
         4 . The system of  claim 1 , wherein the spacing between the uprights is controlled by a rotatable screw which closes the spacing between the uprights as the audience participation signal increases and increases the spacing of the uprights as the audience participation signal decreases.
