ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a dart board that has noise reduction members mounted to guide posts of the dart board so that when a dart hits on a unit of one score ring, the unit is moved and the noise reduction members between the unit reduces the noise.
BACKGROUND OF THE INVENTION
A conventional dart board that can illustrate scores generally includes a circular frame within which a plurality of rings are located and the rings are connected by radial ribs. A plurality of partitions are defined between adjacent two rings. Each partition receives a unit which is moved in the partition and guided by posts extending from the cross-point of the rings and the radial ribs. An electric plate is located on a rear side of the units so that when a dart hits on a unit, the unit is pushed by the dart and moves to compress sensors on the electric plate to show the scores of the unit represents. Because the units are movably engaged in the partitions between the rings and the radial ribs so that when the dart hits the dart board, vibration will shake the units so that noise will generate. The noise affects the sound when the dart penetrates into the unit and the sound generated by penetrating of the dart is one of important factors that players appreciate.
The present invention intends to provide a dart board that reduces the noise of the movement of the units in the partitions when a dart hits the dart board.
SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided a dart board comprising a frame having a central ring and a plurality of ribs extending radially from the central ring. A plurality of ring members are connected to the ribs and shares a common center of the central ring. A plurality of partitions are defined between the ribs and the ring members. Each partition has a target unit movably received therein and an electric circuit plate is located on a rear side of the target units. A base board is connected to the frame and positions the electric circuit plate and the target units between the base board and the frame. A plurality of posts respectively extend from connection points between the ring members and the ribs. Each post has a noise absorbing member mounted thereto and each target unit is movably retained by the noise absorbing members on the posts located on comers of each partition.
The object of the present invention is to provide dart board that has noise absorbing member mounted to posts of a frame, and each target unit is movably retained between the posts so that when the target unit is hit by a dart, the unit moves silently.
