Optical toe line for dart games

Abstract

Disclosed is a dart game wherein the distance from which the darts are to be thrown toward the board is marked optically, using a visible-light generating device, such as a lamp, light-emitting diode, or laser. The game includes a dart board in combination with means for generating and projecting a visible toe line onto a floor in front of the dart board at a pre-set or user-adjustable distance from the front face of the dart board, the means preferably being the previously noted lamp, light-emitting diode, or laser.

What is claimed:  
     
         1 . A game comprising: a dart board having a front face in combination with a means for generating and projecting a visible toe line onto a floor in front of the dart board at a pre-set or user-adjustable distance from the front face of the dart board.  
     
     
         2 . The game of  claim 1 , wherein the means for generating and projecting a toe line comprises a lamp generating light in the visible spectrum.  
     
     
         3 . The game of  claim 1 , wherein the means for generating and projecting a toe line comprises a light-emitting diode generating light in the visible spectrum.  
     
     
         4 . The game of  claim 1 , wherein the means for generating and projecting a toe line comprises a laser generating light in the visible spectrum.  
     
     
         5 . A game comprising: a dart board having a front face in combination with a means for generating and projecting a toe line onto a floor in front of the dart board at a pre-set or user-adjustable distance from the front face of the dart board, wherein the means for generating and projecting the toe line comprises a means selected from the group consisting of a lamp generating light in the visible spectrum, a light-emitting diode generating light in the visible spectrum, and a laser generating light in the visible spectrum.  
     
     
         6 . The game of  claim 5 , further comprising means for acquiring, storing, and manipulating information about players' names and rules for playing and scoring a plurality of dart games; and means for generating a dynamic output of the information and casting an image of the information on the floor in front of the dart board.  
     
     
         7 . The game of  claim 6 , wherein the means for acquiring, storing, and manipulating information comprises a microprocessor; and wherein the means for generating a dynamic output of the information comprises an LED or LCD projector.
