Abstract

A dart board assembly includes a frame having a plurality of block bodies which are movably engaged with spaces defined by ribs extending from the frame. The frame is fixed to a backing and an electronic sensing member is connected between the backing and the frame. A plurality of conducting switches extend from the electronic sensing member. A first surface of a thin and elastic contact pad is connected to the electronic sensing member and a plurality of protrusions protrude from a second surface of the contact pad and a recess is defined in a second surface of the electronic sensing member corresponding to each of the protrusions. A gap is defined between an inside of each recess and the switches. The inside of the recess contacts the conducting switch corresponding thereto when the block body is stricken by a dart and moves the contact pads toward the electronic sensing member.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
         1 . A dart board assembly comprising: 
 a frame having a plurality of ribs and a plurality of spaces defined between the ribs, each space having a block body movably received therein;    a backing and the frame fixedly connected to the backing, an electronic sensing member connected between the backing and the frame, a plurality of conducting switches extending from the electronic sensing member, and    a thin and elastic contact pad having a first surface thereof connected to electronic sensing member, a plurality of protrusions protruding from a second surface of the contact pad and each protrusion defining a recess in the second surface of the contact pad, the recesses facing the switches on the electronic sensing member and a gap defined between the switch and an inside of the recess, the inside of the recess contacting the conducting switch corresponding thereto when the contact pad is moved toward the electronic sensing member.    
     
     
         2 . The assembly as claimed in  claim 1  further comprising a conductive member connected to the inside of each of the recesses.  
     
     
         3 . The assembly as claimed in  claim 1  further comprising a convex portion extending from the inside of each of the recesses.  
     
     
         4 . The assembly as claimed in  claim 3  further comprising a conductive member connected to a surface of each of the convex portions.  
     
     
         5 . The device as claimed in  claim 1  further comprising a plurality of bosses connected to the rear surface of each of the block bodies and the protrusions contacting the bosses.
