Description:
BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates to darts and more particularly, to a dart and dartboard set for the game of darts that is safe in use and convenient to carry. 
   2. Description of the Related Art 
   A regular electronic dartboard, as shown in  FIG. 1 , is comprised a base frame  10 , a rim  11 , a dartboard body  12 , a plurality of dartboard blocks  13 , an induction wheel  14 , and a back frame  15 . The dartboard body  12  is a meshed structure having open spaces for accommodating the dartboard blocks  13 . When the player threw the dart  16  (see  FIG. 2 ) at one dartboard block  13 , the respective dartboard block  13  is moved relative to the dartboard body  12  to touch the induction wheel  14 , causing the induction wheel  14  to induce a signal and to send the induced signal to a control circuit board (not shown) for counting the score for enabling the counted score to be shown on the display screen  17  at the base frame  10 . 
   The aforesaid dart  16  is not safe in use. Because the dart  16  has a point  161  for piercing the dartboard blocks  13 , the point  161  may injure the player accidentally. Further, the aforesaid dartboard is not easy to manufacture and assemble because of its complicated structure. The high thickness of this structure of dartboard makes the dartboard not convenient to carry.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
   Referring to  FIGS. 3˜5 , a dart and dartboard set in accordance with the present invention is comprised of a magnetic dartboard and a number of darts 
   The dartboard according to the present invention comprises a face fabric panel  20 , which has a score ring pattern  201  printed thereon, a back fabric panel  21 , a flexible magnetic panel  30  sandwiched between the face fabric panel  20  and the back fabric panel  21 , a first induction circuit membrane  40 , which is sandwiched between the face fabric panel  20  and the flexible magnetic panel  30 , having a plurality of induction zones  401  corresponding to the score ring pattern  201  of the face fabric panel  20 , an output connector  403 , and a plurality of lead wires  402  respectively extending from the induction zones  401  to the output connector  403 , a second induction circuit membrane  41 , which is sandwiched between the flexible magnetic panel  30  and the back fabric panel  21 , having a plurality of induction zones  411  corresponding to the score ring pattern  201  of the face fabric panel  20 , an output connector  413 , and a plurality of lead wires  412  respectively extending from the induction zones  411  to the output connector  413 . 
   The magnetic dartboard further comprises a frame structure that holds the face fabric panel  20 , the first induction circuit membrane  40 , the flexible magnetic panel  30 , the second induction circuit membrane  41  and the back fabric panel  21  together, and a control circuit assembly  60 . The frame structure comprises two fabric packing strips  50  fastened to the left, right and bottom sides of the stacked structure of the face fabric panel  20 , the first induction circuit membrane  40 , the flexible magnetic panel  30 , the second induction circuit membrane  41  and the back fabric panel  21  with stitches, and a clip  51  fastened to the top side of the stacked structure of the face fabric panel  20 , the first induction circuit membrane  40 , the flexible magnetic panel  30 , the second induction circuit membrane  41  and the back fabric panel  21 . The clip  51  is comprised of two elongated clamping strips  511  and  512 . The two clamping strips  511  and  512  are respectively attached to the face fabric panel  20  and the back fabric panel  21  at the top and fastened together with screws  513  to hold the stacked structure of the face fabric panel  20 , the first induction circuit membrane  40 , the flexible magnetic panel  30 , the second induction circuit membrane  41  and the back fabric panel  21 . One clamping strip  512  has a plurality of studs  54  respectively inserted through respective through holes  53  on the stacked structure of the face fabric panel  20 , the first induction circuit membrane  40 , the flexible magnetic panel  30 , the second induction circuit membrane  41  and the back fabric panel  21  and connected to the other clamping strip  511 . Further, the clip  51  is provided with a hanging ring  55  for hanging on a wall nail. 
   The aforesaid control circuit assembly  60  is fastened to the bottom side of the stacked structure of the face fabric panel  20 , the first induction circuit membrane  40 , the flexible magnetic panel  30 , the second induction circuit membrane  41  and the back fabric panel  21 , comprising a display screen  61 , two sound effect output devices, i.e., speakers  62 , selector buttons  63 , a power switch  64 , a sound effect switch  65 , indicator lights  66 , a control circuit board  67 , a power supply device  68 , and a buzzer  69 . The output connectors  403  and  413  of the induction circuit membranes  40  and  41  are respectively electrically connected to the control circuit board  67  for signal output to the control circuit board  67 . The selector buttons  63  are for selection of games and scoring modes preset in the control circuit board  67 . After selection of the desired game, the control circuit board  67  drives the display screen  61  to display the selected game mode and the buzzer  69  to output a predetermined music through the speakers  62 . When the game is started, the indicator lights  66  are alternatively turned on in proper order subject to the order of the players. The power switch  64  controls on/off status of the control circuit assembly  60 . The sound effect switch controls on/off of the preset sound effect (music). When a score is obtained during play of the game, the control circuit board  67  drives the display screen  61  to display the corresponding score. 
   Referring to  FIG. 6 , the dart  70  is molded from plastics, having a front end fixedly mounted with a magnet  72  and a rear end terminating in a flight  71 . The magnet  72  is a flat magnet, having a flat front face  721 . 
   Referring to  FIGS. 7 and 8 , when the player throwing the dart  70  toward the magnetic dartboard, the magnetic attractive force of the flexible magnetic panel  30  attracts the magnet  72  of the dart  70 . Subject to the hit location of the dart  70 , the respective induction zones  401  and  411  of the induction circuit membranes  40  and  41  are induced to output a corresponding signal to the control circuit board  67 , which counts the score subject to the resistance value of the induced signal and drives the display screen  61  to display the score. 
   Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
