ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a dart board that does not generate noise when the blocks are hit by the darts.
BACKGROUND OF THE INVENTION
A conventional dart board is shown in FIG.
6
and generally includes a frame
10
which is connected on a backing plate
13
and a plurality of electronic members
12
are connected on the backing plate
13
. The frame
10
includes a plurality of partitions separated by ribs on the frame
10
and each partition receives a block
11
therein. A dart
14
hits one of the blocks
11
and the block
11
being hit moves toward the backing plate
13
and activates the electronic members
12
so as to display scores that the throw gains. It is necessary to maintain a gap between the inside of the partitions and the blocks
11
so that the blocks
11
are allowed to move toward the backing plate
13
. Nevertheless, noise is generated when the block
11
is moving and the impact between the blocks
11
and the frame
10
no matter what material is used to make the block
11
. Besides, other blocks
11
that do not hit could shake and generate noise. The noise really reduces the feeling of entertainment of the players.
SUMMARY OF THE INVENTION
The present invention relates to a dart board which comprises a backing plate and a frame is connected to the backing plate. A plurality of ribs extend from the frame to define a plurality of partitions in which a plurality of blocks are movably received respectively. Each block has flexible convex portions which contact an inside of the ribs defining the partition. A plurality of spring members are connected between the backing plate and the blocks.
The primary object of the present invention is to provide a dart board that generates no noise when the darts hits the blocks.
