ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a dart target with a function of automatically displaying scores, and especially to a low cost and convenient dart target with a high efficiency.
BACKGROUND OF THE INVENTION
In the prior art, the conventional dart has a metal tip, and the target body is made of a sisal block without a function of displaying score.
FIGS. 1A and 1B
shows another prior art dart toy which is primarily formed by target body
21
. The target body
21
includes a plurality of targets
201
,
202
,
203
, . . . , with holes therein, a dart frame
23
. The targets
201
,
202

203
, . . . are located in an object frame
20
. On the target body
21
, a score display
24
and a plurality of buttons are installed. When the tip of the dart
25
inserts into the holes
201
A,
201
B, . . . of the targets, it will touch switch
26
in the target
26
so that the switch is closed. Then a signal will pass through the wire
27
to a processing circuit. Then, the signal is connected to a score display
24
for displaying the score.
However some defects is existed in this prior art design.
1. In order that as the tip of the dart inserts into the targets, it will not destroy the switch, and is fixed therein, the tip of the dart needle generally must be made of nylon. However, such material is easily broken or bent so as not to be sustained in equilibrium as a large force is applied on the dart.
2. A plurality of holes must be formed on the target, the cost is high.
SUMMARY OF THE INVENTION
Accordingly, the primary object of the present invention is to provide a dart target with a function of automatically displaying scores. The dart target is installed with a damping panel. The damping panel is formed by at least one damping layer; the damping layers are made of flexible and transmitted cloth, such as sisal, non-woven cloth, etc. Thus, a metal dart can be used. As the dart passes through the target panel, it can be damped by the damping layer and fixed therein. A pattern is formed at the surface of the first damping layer so that the dart player may identify the target. The target panel is a plane for being used by metal dart head, and the score can be displayed properly.
Another object of the present invention is to provide a dart target with a function of automatically displaying scores, wherein a damping net is installed at the front end of the displaying panel. When the metal dart head impinges into the target, by the damping of the damping net, the displaying panel will not be harmed. Therefore, a low cost and convenient dart target with a high efficiency is provided by the present invention.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.
