Description:

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a dart board game, and more particularly to a method for generating reference lines for dart games, and for avoiding the users from drafting reference lines or 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 are required to be drafted in front of the dart boards, and the players should stand behind the reference lines to play the dart games.

The distance between the reference line and the dart boards is normally ranged from about seven (7) to nine (9) feet. For example, the distance between the reference 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 ΒΌ) inches in the United States.

However, till today, the reference 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 reference line and the dart boards, and then may have to draft the reference lines. The reference 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. 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 and dart games.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide a method for generating reference lines or toe lines for dart games, and for avoiding the users from drafting the reference lines or the toe lines manually.

In accordance with one aspect of the invention, there is provided a method for dart games includes one or more reference line generating devices attached to a dart board or to a wall, to generate one or more reference lines in front of the dart board as toe lines, and to avoid the users or the players from drafting the reference lines or the toe lines manually, and from drafting the reference lines or the toe lines every time when the players are going to play the dart games.

The reference line generating device includes a light generating device for generating the reference line or the toe line. A housing is provided to receive the light generating device. A circuit board may be provided to support the light generating device. A casing may be provided in front of the housing to receive the light generating device. A lens may be provided in the casing and disposing in front of the light generating device. A passage may be provided in the casing to receive the lens therein.

An attaching device may be provided for attaching the reference line generating device to the dart board or to the wall, and includes at least one arm having a first end attached to the dart board, and a second end for supporting the reference line generating device, and an extension laterally extended from the first end of the arm, and secured to the dart board with at least one fastener.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to the drawings, and initially to FIGS. 1 and 2, a method in accordance with the present invention is to provide a dart board 10 which may be directly and erectly supported on desks, or the like, or may be attached or secured onto a dart board cabinet (not shown), a supporting surface or wall 80 or the like. The dart board 10 includes 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 method in accordance with the present invention is to further provide and attach or secure one or more reference line generating devices 30 onto the dart board 10 (FIGS. 1, 5, 6), or onto the dart board cabinet (not shown), or onto the supporting surface or wall 80 or the like (FIGS. 2, 7, 8), with a coupling or attaching means or device 20.

For example, as shown in FIGS. 3 and 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 (FIGS. 1, 5, 6), or directly onto the supporting surface or wall 80 or the like (FIGS. 2, 7, 8).

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. 5-8.

The housing 31 of the reference line generating device 30 includes a chamber 32 formed therein for receiving a circuit board 40 or the like therein, and includes a casing 33 provided or extended in front portion thereof.
