Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to a dart board assembly, and more particularly to a dart board assembly having a device for generating reference lines or toe lines and for avoiding the users from drafting the reference lines or the toe lines manually.
2. Description of the Prior Art
Various kinds of typical dart boards have been developed and comprise a number of darts areas or dart segments to be hit by darts. In addition, various kinds of dart games have been developed for being played by one or more players.
For almost all of the dart games, one or more reference lines or toe lines are required to be drafted in front of the dart boards, and the players should stand behind the reference lines or the toe lines to play the dart games.
The distance between the reference line or the toe line and the dart boards is normally ranged from about seven (7) to nine (9) feet. For example, the distance between the toe line and the dart boards is about seven (7) feet and six (6) inches in Great British, and is about seven (7) feet and nine and a quarter (9 and ¼) inches in the United States.
However, till today, the toe lines are still drafted in front of the dart boards by the players manually, with such as chalk, pen, or the like. Before playing the dart games, the players may have to measure the distance between the toe line and the dart boards, and then may have to draft the toe lines. The toe lines drafted by chalk, pen, or the like normally may not be last for long time.
The players may chose some of the lines or objects, that have been previously formed or provided on the ground or the like, as the reference lines or the toe lines. However, it will be difficult to find a support surface or a support wall to support the dart boards, and to have the support surface or the support wall to be exactly located in the required distance away from the selected lines or objects.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional dart boards.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to the drawings, and initially to FIG. 1, a dart board assembly in accordance with the present invention comprises a dart board 10 including a spider 11 to separate the front portion of the dart board 10 into a number of dart areas or dart segments 12 that are to be hit by darts (not shown). The dart board 10 may include a control panel 14 to control the dart games to be played by the players, for example.
The dart board assembly further includes one or more reference line generating devices 30 to be attached to the dart board 10 with a coupling or attaching means or device 20. For example, as shown in FIGS. 2-4, the attaching device 20 includes one or more arms 21 each having an extension 22 bent or extended laterally from one end thereof, and one or more orifices 23 formed in the arms 21 or extensions 22, for receiving fasteners 24 which may secure the arms 21 to the dart board 10.
The attaching device 20 further includes one or more apertures 25 formed in the other end of the arms 21, for receiving fasteners 26 which may be used to secure the reference line generating device 30 to the arms 21. For example, the reference line generating device 30 may include a housing 31 rotatably secured to the arms 21 with the fasteners 26, to allow the housing 31 of the reference line generating device 30 to be rotated and adjusted relative to the dart board 10 to any selected angular positions, best shown in FIGS. 4, 5.
