Description

FIELD OF THE INVENTION

The present invention relates to a dart board and more particularly to an electronic dart board and particularly to an improvement of a conventional electronic dart board.

The term metal dart as used herein is intended to distinguish the electronic dart board set from traditional dart which is made of plastic.

The present invention with its metal dart may show the precise position and marks of each throwing.

SUMMARY OF THE INVENTION

Accordingly it is an object of this invention to overcome the disadvantages of the prior art.

More particularly, it is an object of the present invention to provide an improved dart board which comprises an elastic body with pressure cover.

BRIEF DESCRIPTION OF THE DRAWINGS

The invention can be more fully understood by reference to the following description and accompanying drawings, in which:

FIG. 1 (prior art) is a sectional view of a conventional electronic dart board;

FIG. 2 is a front view of the electronic dart board of the invention;

FIG. 3 is an exploded view of the electronic dart board of the invention;

FIG. 4 is an exploded view of a target plate in the electronic dart board of the invention;

FIG. 5 is a sectional view of the electronic dart board of the present invention, taken along the line A--A of FIG. 2; and

FIG. 6 is an exploded view of a target plate of the electronic dart board of the invention in another embodiment.

BACKGROUND OF THE PRIOR ART

As shown in FIG. 1, a conventional electronic dart board has a surface with through holes. A dart hitting the surface is supposed to penetrate one of the holes and touch a membrane switch. A conventional electronic dart board, however, has several drawbacks. If the direction of incidence is not parallel to the through holes, the membrane switch at the end of the hole will not be touched. The probability of hitting the holes at the proper angle of incidence is low. Finally, the surface of a conventional electronic dart board is made of hard material, and the head of the dart is made of plastic, so that if the dart does not properly hit a hole, its head is easily deformed or even breaks. A dart with a deformed or broken head cannot be used again and has to be replaced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 2 and 3, the electronic dart board of the present invention mainly comprises a target frame 10, a base plate 20 and a plurality of target plates 30. The target frame 10 has a plurality of fixing tabs 12, and the base plate 20 has a plurality of fixing tabs 28, which are aligned with the fixing tabs 12, when the target frame 10 is laid on the upper side of the base plate 20. In this manner the target frame 10 and the base plate 20 are fixed to each other. The target frame 10 has on its upper side a plurality of display shields 11. An illuminator 24, shown in FIG. 5 is inserted in a positioning hole 22 on the base plate 20. The display shields 11 allow the illuminator 24 to be visible through the target frame 10. On the inner periphery of the target frame 10, target plates 30 are mounted. They may be of polygonal shape but various shapes for the target plates 30 are possible.

As shown in FIGS. 3 and 4, each target plate 30 comprises a press cover 31 and soft body 32. The soft body is glued to the inner border of the press cover 31 and is surrounded by a rim on the periphery of the press cover 31.

From the lower side of the press cover 31, close to the periphery thereof, press bars 33 extend downwards. The press bars point to membrane switches 23, which are attached to the upper surface of the base plate 20. When the target plate 30 is pressed down, towards the base plate 20, the press bars 33 act on the membrane switches 23, causing the illuminator 24 to be turned on. In the middle of the surface of the target plate 30, a fish eye hole 34, is bored through. A screw 27 passes through the fish eye hole 34 further through a spring 25 below the fish eye hole 34 and a through hole 21 in the base plate 20. A nut 26 holds the lower end of the screw below the base plate 20.

Referring to FIG. 5, when a dart 40 hits the soft body 32, the press cover 31, due to the elastic force of the spring 25, sways back and forth, so that at least one of the press bars 33 touches one of the membrane switches 23, causing the illuminator 24 to give off light.

Referring to FIG. 6, the electronic dart board of the present invention in another embodiment has target plates, each of which comprise several press covers 50 and soft bodies 51 of different sizes. Each of the soft bodies 51 fits on one press cover 50. Thereby various scores can be introduced into the game, adding to the fun of it.
