Abstract

The number of void throws due to falling of the darts from the board is reduced by a 'homing' effect. This is achieved by the positive hammer action produced by the forward movement of a hammer 7 incorporated within the body of the dart. The forward movement of the hammer on impact imparts an acceleration. <IMAGE>

Description

SPECIFICATION Homing dart This invention relates to a device which will improve the performance of a common dart and in particular wiil reduce the number of failure throws resulting from dropping of the darts from the dartboard.

In darts, in normal circumstances, when in a particular throw if the dart falls off the dartboard, that throw is rendered void. Also, if in this event any previously lodged darts fall off the dartboard, they are considered void too, and effectively the player looses his score. It is very important to minimise the number of no-score throws in competition games.

The falling of darts from the dartboard can take place in several ways: 1. When the dart hits a wire on the board.

2. When the throw is not powerful enough.

3. When two or more darts lodge very close together.

4. When the penetration of the dart on the dartboard is not deep enough.

5. When the game has been going on for several hours, the throws become too weak due to the fatigue of the player.

It is an object of th is invention to provide considerable and effective improvement in the performance of the dart throws, especially in competition darts.

It is yet another object of this invention to help to reduce and minimise the number of void or no-scorethrnws.

It is yet another object of this invention to reduce the effort required to produce sufficient enough depth of penetration of the dart on a dartboard.

It is yet another object of this invention to assist the dart to 'home-in' even if the dart hits a wire off-centre.

These and other objects of the present invention shall become more apparent to those skilled in the art upon careful study of the detailed description of the claims and drawings.

The important feature of the present invention is the so called 'hammer' 6.

The improved performance i.e. the 'homing' effect is achieved by the positive hammer action produced by the forward movement of the hammer 6 on impact with the striking face 3 and thus imparting an acceleration, hence an extra force on the dart producing greater penetration of the point 1 on the dartboard.

The hammer 6 can be made from tungsten, mild steel or mercury in a container.

In the drawings: FIG. 1 is a sectional view of a common dart showing point 1, body 2 and flight 5.

FIG. 2 is a sectional view of the improved performance dart embodying the fundamental feature of the present invention.

FIG. 3 is a sectional view of the improved performance dart embodying additional features.

The additional features are a keep 9, a carbon magnet 8 and air-vents 10.

The keep 9 prevents the hammer 6 from failing out of the base 4 of the body 2 in the event of attempting to change the flight 5 from the body base 4.

The magnet 8 prevents the hammer 6 from 'to and fro' movements within the body, while the player tries his throw.

The keep 9 can be of a section of a spring or a circlip, magnetised or unmagnetised. If the keep 9 is magnetised, then a separate magnet 8 is not required. In the case wherein the hammer is made from a non-magnetic material, the end of the hammer nearest to the flight can be made magnetic.

The clearance 7 is sufficient enough for the free movement of the hammer 6 within the body of the dart.

The air-vents 10 can be incorporated near the striking face 3 for the escape of the pressurised air produced due to the forward movement of the hammer on impact.

1. An improved performance dart which has a 'homing' effect induced by the forward movement of a hammer incorporated within the body of the dart.

2. A dart as claimed in Claim 1 wherein the forward movement of the hammer produces a positive hammer action, thus imparting an acceleration and a dynamic effect.

3. A dart as claimed in Claims 1 and 2 wherein it produces a deeper penetration of the dart on the dart board.

4. A dart of Claim 1 produces a deeper implant of the dart without extra effort in the usual throw of a dart.

5. A dart of Claims 1 and 4 wherein less effort is required to obtain the same depth of penetration; i.e. a dart without the hammer requires more power in the throw to obtain the same depth of implant than a dart as claimed in Claim 1.

6. A dart of Claims 1 and 3 helps the dart to remain on the dart board and thus avoid void throw and minimise void throws.

7. A dart of Claims 1 and 2, wherein the dart hits a wire off-centre the hammer action pulls it into the board and effectively prevents the dart falling off the board.

8. A dart of Claims 1 and 3 helps the dart to remain on the board even if two or more darts are lodged very close together.

9. A dart of Claims 1 and 5 is particularly helpful for players when they become tired and the throws become weak in long competition matches.

10. A dart of Claim 1 has a carbon magnet which prevents the 'to and fro' movement of the hammer within the body of the dart when the player tries a throw.

11. A dart of Claim 1 has a 'keep' which may be

11. A dart of Claim 1 has a 'keep' which may be a section of a spring or a circlip, magnetised or unmagnetised. The keep prevents the hammer from falling out of the body of the dart in the event of a player attempting to change and or renew the flight from the base of the dart.

12. A dart of Claim 1 has sufficient clearance within the body for the free movement of the hammer within the body.

13. A dart of Claim 1 has air vents near the striking face (nose end). These vents allow the escape of the pressurised air produced due to the movement of the hammer on impact. The hammer may be of mild steel material or a heavier like tungsten, or mercury filled in a container. In the case of the hammer made of non-magnetic material, the end of the hammer near to the flight (tail end) can be made magnetic for use with a 'keep' made of magnetic material.
