Description

本発明は、壁などに用意された的（ダーツボード）に矢を当てて得点を競うダーツの改良に関するものである。   The present invention relates to an improvement of a dart that competes for a score by hitting an arrow on a target (dart board) prepared on a wall or the like.

ダーツは、バレルと、バレルの先端部に取り付けられるチップと、バネルの後端部に取り付けられるシャフトと、シャフトに取り付けられるフライトとから構成される。これらのダーツ構成部材のうちバレルは、いわゆるダーツの本体で、プレーヤーがダーツを投げる際に手に持つ部分であり、この部分の掴み易さと共に、その重量及び重心位置によって結果が左右されることから、バレルはダーツにおいて非常に重要な役割を果たしている。特にダーツゲームでは、ダーツの重量及び重心位置を変えることによって、プレーヤーは様々なプレースタイルを実現して、より高い得点を上げることができるとされている。   The dart is composed of a barrel, a tip attached to the tip of the barrel, a shaft attached to the rear end of the bunnel, and a flight attached to the shaft. Among these dart components, the barrel is the so-called dart body, which is the part that the player holds in throwing the dart, and the result depends on the weight and center of gravity position, as well as the ease of grasping this part. So barrels play a very important role in darts. Particularly in the dart game, it is said that by changing the weight of the dart and the position of the center of gravity, the player can realize various play styles and raise a higher score.

従来のダーツとして、特許公報等の公知文献を具体的な上げることはできないが、従来使用されているダーツでは、バレル自体の重量及び重心位置が固定されているため、プレーヤーは、プレースタイルに応じて、夫々重量及び重心位置の種々異なった多数のバレルを用意する必要があった。   Known darts such as patent gazettes cannot be specifically raised as conventional darts. However, in conventional darts, the weight and center of gravity of the barrel itself are fixed. Therefore, it is necessary to prepare a large number of barrels having different weights and positions of the center of gravity.

本発明は、バレルの重量及び重心位置を自由に変更できるようにしたダーツを提供することを目的とする。   An object of this invention is to provide the dart which enabled it to change freely the weight of a barrel, and a gravity center position.

上記課題を解決するための手段を、後述する実施形態の参照符号を付して説明すると、本発明の請求項１に係る発明は、バレル１と、バレル１の先端部に取り付けられるチップ２と、バレル１の後端部に取り付けられるシャフト３と、シャフト３に取り付けられるフライト４とからなるダーツにおいて、
バレル１内部には軸方向中央部の隔壁１ｏを挟んでその前後両側にバレル１の両端に開口するネジ孔８，９を形成し、チップ２の後端部にはバレル１の前部側ネジ孔８に螺合する取付用ネジ部１１を、シャフト３の先端部には後部側ネジ孔９に螺合する取付用ネジ部１２を夫々形成する一方、バレル１の各ネジ孔８，９に螺入可能で重量の異なる複数種類の錘片５，６，７を設け、これら錘片５，６，７を選択的にバレル１の前部側ネジ孔８及び後部側ネジ孔９に螺入することによって、バレル１の重量及び重心位置を変えるようにしたことを特徴とする。 Means for solving the above problems will be described with reference numerals of the embodiments described later. The invention according to claim 1 of the present invention includes a barrel 1 and a chip 2 attached to the tip of the barrel 1. In the dart consisting of the shaft 3 attached to the rear end of the barrel 1 and the flight 4 attached to the shaft 3,
Inside the barrel 1, screw holes 8 and 9 are formed at both ends of the barrel 1 on both sides of the partition wall 1 o at the center in the axial direction, and the front side screw of the barrel 1 is formed at the rear end of the chip 2. An attachment screw portion 11 that is screwed into the hole 8 is formed, and an attachment screw portion 12 that is screwed into the rear screw hole 9 is formed at the front end portion of the shaft 3, while each of the screw holes 8 and 9 of the barrel 1 is formed. A plurality of types of weight pieces 5, 6, 7 that can be screwed and have different weights are provided, and these weight pieces 5, 6, 7 are selectively screwed into the front side screw hole 8 and the rear side screw hole 9 of the barrel 1. Thus, the weight and the position of the center of gravity of the barrel 1 are changed.

尚、ダーツは、使用するダーツの矢先、的によってハードダーツとソフトダーツに分けられており、ハードダーツは、ブリッスルボードと呼ばれる麻でできた的に対し、金属製のチップを付けた矢（ダーツ）を投げるものであり、またソフトダーツは、プラスチック製の穴の開いた的に対し、プラスチック製のチップを付けた矢を投げるものであるが、この発明に係るダーツは、ハードダーツ及びソフトダーツの何れにも適用可能である。     The darts are divided into hard darts and soft darts depending on the tip of the darts used, and the hard darts are arrows made of hemp called bristle boards with arrows with metal tips (darts). The soft dart is for throwing an arrow with a plastic tip against the target with a plastic hole. The dart according to the present invention is a hard dart and a soft dart. It is applicable to any of these.

請求項２は、請求項１に記載のダーツにおいて、前記複数種類の錘片５，６，７は、夫々同じ金属材で形成された長さの異なるものからなることを特徴とする。   According to a second aspect of the present invention, in the dart according to the first aspect, the plurality of types of weight pieces 5, 6, and 7 are made of the same metal material and have different lengths.
