Dartboard

Abstract

A dartboard consists of an electronic plate ( 40 ), a base board ( 42 ) mounted on the electronic plate ( 40 ), a frame ( 10 ) having multiple compartments ( 12 ), multiple dart blocks ( 20 ) loosely mounted inside the respective compartments ( 12 ) and a window frame ( 70 ) mounted on the frame ( 10 ). Improvements of the dartboard include multiple cutouts ( 14 ) being defined in the frame ( 10 ) division walls ( 11 ) around the compartments ( 12 ) allow the frame ( 10 ) to accommodate slight variations in the size of dart blocks ( 20 ); each dart block ( 20 ) having a dart box ( 21 ) with smooth outer surfaces to make the dart block ( 20 ) easily move inside the compartment ( 12 ); and a contact pin ( 241 ) formed under the dart block ( 20 ) to actuate the electronic plate ( 40 ). All improvements in configuration make the dartboard precisely calculate scores.

What is claimed is:  
     
         1 . A dartboard comprising: 
 an electronic plate ( 40 ) having multiple sensing points on a front face;    a base board ( 42 ) mounted on the front face of the electronic plate ( 40 ) and having multiple holes ( 423 ) to correspond to the sensing points of the electronic plate ( 40 );    a main frame ( 10 ) mounted on the base board ( 42 ) with multiple compartments ( 12 ) defined in the main frame ( 10 );    multiple dart blocks ( 20 ) having smooth outer surfaces, an open front face and closed rear face loosely mounted in the compartments ( 12 ); and    a window frame ( 70 ) mounted on the main frame ( 10 ) to keep the dart blocks ( 20 ) inside the compartments ( 12 );    wherein the improvements of the dartboard comprise: 
 the main frame ( 10 ) having multiple division walls ( 11 ) to define multiple compartments ( 12 ) in the main frame ( 10 ) and multiple cutouts ( 14 ) defined in the division walls ( 11 ) at positions corresponding to the compartments ( 12 ).  
   
     
     
         2 . The dartboard as claimed in  claim 1 , wherein the cutouts ( 14 ) are U-shaped.  
     
     
         3 . The dartboard as claimed in  claim 1 , multiple first round flanges ( 24 ) are formed on the outside of the rear face, and a contact pin ( 241 ) is formed at a center of each first round flange ( 24 ); 
 the base board ( 42 ) further has multiple second round flanges ( 421 ) formed around the holes ( 423 ) and corresponding to the respective multiple first round flanges ( 24 ); and    a resilient element ( 23 ) is mounted around each contact pin ( 241 ) and has two ends mounted within the corresponding first round flange ( 24 ) and the second round flange ( 421 ).    
     
     
         4 . The dartboard as claimed in  claim 2 , wherein multiple first round flanges ( 24 ) are formed on the outside of the rear face, and a contact pin ( 241 ) is formed at a center of each first round flange ( 24 ); 
 the base board ( 42 ) further has multiple second round flanges ( 421 ) formed around the holes ( 423 ) and corresponding to the respective multiple first round flanges ( 24 ); and    a resilient element ( 23 ) is mounted around each contact pin ( 241 ) and has two ends mounted within the corresponding first round flange ( 24 ) and the second round flange ( 421 ).    
     
     
         5 . The dartboard as claimed in  claim 4 , wherein the resilient elements ( 23 ) are springs.  
     
     
         6 . The dartboard as claimed in  claim 1 , wherein the dart block ( 20 ) comprises a dart box ( 21 ) and stuffing ( 22 ) made of soft material inside the box ( 21 ).  
     
     
         7 . The dartboard as claimed in  claim 2 , wherein the dart block ( 20 ) comprises a dart box ( 21 ) and stuffing ( 22 ) made of soft material inside the box ( 21 ).
