Description

  The present invention relates to a dart barrel, a dart provided with a dart barrel, and a dart barrel component set.

  A dart used in a dart game generally includes a chip that pierces a dart board, a dart barrel to which the chip is connected, and a shaft and a flight that are connected to the dart barrel. Among them, the design of dart barrels has been diversified in recent years, and dart players are demanding individuality through dart design. The dart barrel is often provided with a groove for improving finger hooking, etc., but it is insufficient in terms of design, and there is a demand for a dart barrel with more individuality.

A screw part integrated with the side member 42 may be screwed together.

  As shown in FIG. 1, the ring-shaped member 43 has a decorative portion 43 a on the outer periphery. In the present embodiment, the decorative portion 43 a is a character carved on the outer periphery of the ring-shaped member 43. The decoration part 43a is a part mainly subjected to a decorative design, but a groove or the like on a functional surface may be formed. The decoration part 43a can be made into various decorations, such as a character, a figure, a design, a pattern, for example. These decorations may be formed in a groove shape by engraving the ring-shaped member 43 or may be raised from the surface of the dart barrel 4. Moreover, the decoration part 43a may be formed by processing the base material of the ring-shaped member 43 by cutting or the like, or may be provided by attaching another material to the base material of the ring-shaped member 43.

  The ring-shaped member 43 is shorter than the front end side member 41 and the rear end side member 42 in the axial direction, and is formed in a ring shape. The ring-shaped member 43 is disposed between the front end side member 41 and the rear end side member 42 in the axial direction. Therefore, even if various decorations are applied to the ring-shaped member 43, it is difficult to affect the weight of the entire dart barrel 4. In addition, the length of the axial direction of the front end side member 41, the rear end side member 42, and the ring-shaped member 43 is not limited to the ratio shown in figure, It can change suitably.

  The material of the ring-shaped member 43 is not particularly limited. For example, the ring-shaped member 43 may be made of metal or resin. The ring-shaped member 43 preferably has high workability and low specific gravity. By using a material with high workability for the ring-shaped member 43, the ring-shaped member 43 can be easily processed into a predetermined design. Further, by using a material having a small specific gravity for the ring-shaped member 43, the influence on the weight balance of the dart barrel 4 and the overall weight can be reduced. Examples of the material having high workability and low specific gravity include aluminum, stainless steel, and synthetic resin.

  In addition, the material of the front end side member 41 and the rear end side member 42 is not particularly limited, and various materials are combined in consideration of the weight balance of the rear center of gravity, the front center of gravity, the center of center of gravity, and the total weight of the dart barrel 4. Can be used. The material of the screw portion 44 is not particularly limited, but is made of a material having a specific gravity smaller than that of the front end side member 41, the rear end side member 42, and the ring-shaped member 43 in consideration of the influence on the weight balance. Is preferred. As the screw part 44, for example, brass can be used.

  When manufacturing the dart barrel 4 having the front center of gravity, the rear end side member 42 and the ring-shaped member 43 are made of a material having a specific gravity smaller than that of the front end side member 41. In this case, for example, tungsten or the like can be used for the distal end side member 41. Further, the rear end side member 42 can be made of aluminum, stainless steel, titanium, brass, synthetic resin, or the like.

  When manufacturing the dart barrel 4 having the front center of gravity, the ring-shaped member 43 may be made of a material having a specific gravity smaller than that of the rear end side member 42 or a material having a specific gravity larger than that of the rear end side member 42. It may be constituted by.

  When manufacturing the dart barrel 4 having the rear center of gravity, the front end side member 41 and the ring-shaped member 43 are made of a material having a specific gravity smaller than that of the rear end side member 42. In this case, for example, the rear end side member 42 can use tungsten or the like. The tip side member 41 can be made of aluminum, stainless steel, titanium, brass, synthetic resin, or the like.

  When manufacturing the dart barrel 4 having the rear center of gravity, the ring-shaped member 43 may be made of a material having a specific gravity smaller than that of the distal end side member 41 or a material having a specific gravity larger than that of the distal end side member 41. May be.

  When manufacturing the dart barrel 4 with the center of gravity, it is preferable to use the same specific gravity material for the front end side member 41 and the rear end side member 42, more preferably the same material.

  As described above, the dart barrel 4 of this embodiment includes the front end side member 41, the rear end side member 42, and the front end side member 41 and the rear end side member 42 between the front end side member 41 and the rear end side member 42 in the axial direction. The ring-shaped member 43 is shorter than the end member 42 in the axial direction and has a decorative portion 43a formed on the outer periphery. Thereby, after adjusting the whole weight and weight balance of the dart barrel 4 by the combination of the front end side member 41, the rear end side member 42, and the ring-shaped member 43 provided therebetween, the design of the dart barrel 4 is achieved. It is very easy to improve the performance. For example, even when tungsten or the like, which is difficult to be finely decorated, is used for either the front end side member 41 or the rear end side member 42, the ring-shaped member 43 can be easily decorated with improved design. . Further, since there is no need to give a fine decoration to the front end side member 41 or the rear end side member 42, it is very easy to design a weight balance (a complicated design can be applied to the front end side member 41 or the rear end side member 42). If formed, the weight balance tends to be lost). In addition, the ring-shaped member 43 is formed in a ring shape having a short axial length, and is disposed between the front end side member 41 and the rear end side member 42, so that the weight balance is affected. It is difficult to design the weight balance of the dart barrel 4 and the design can be easily improved.

  In addition, as above-mentioned, it is preferable that the ring-shaped member 43 is comprised from the material whose workability is better than the front end side member 41 and the rear end side member 42. FIG. In this case, it becomes easy to give a complicated decoration to the ring-shaped member 43, and even if the material which the front end side member 41 and the rear end side member 42 are difficult to process is used, the design can be easily improved. As described above, when a material with good workability and low specific gravity is used for the ring-shaped member 43, the influence of the ring-shaped member 43 on the weight balance of the dart barrel 4 can be further reduced.

  In the present embodiment, the front end side member 41, the rear end side member 42, and the ring-shaped member 43 are screwed together by the screw portion 44. Therefore, for example, when the ring-shaped member 43 to be decorated is completed, the dart barrel 4 is used with the front end side member 41, the rear end side member 42, and the ring-shaped member 43 temporarily connected by the screw portion 44. The player who plays can also throw a dart 1 trial. In that case, when the dart barrel 4 that is temporarily connected has a different image of the player in terms of weight balance and overall weight, the ring-shaped member 43 is used as it is, and either the front end side member 41 or the rear end side member 42 is used. By replacing these, the dart barrel 4 can be easily made as the player's image. On the other hand, when applying a complicated decoration to the dart barrel, as in the conventional case, when the dart barrel is composed of one part, or when it is composed of only the front end side member and the rear end side member, When throwing a dart, the dart barrel may be different from the player's image in terms of weight balance and total weight. In this case, in the conventional dart barrel, the decoration part is integrated with other parts (one-part dart barrel, front end side member with decoration, and rear end side member). The rear end side member is wasted. In that respect, the dart barrel 4 of the present embodiment can utilize the ring-shaped member 43 including the decorative portion 43a, which is difficult to process, even if the image of the player is different when trial throwing, The total manufacturing cost of the dart barrel 4 can be reduced.

  Next, the dart barrel component set S will be described with reference to FIG. In addition, the description about the part which is common in the dart barrel 4 mentioned above is abbreviate | omitted. As shown in FIG. 3, the dart barrel component S set includes a plurality of types of front end side members 410, 411, 412, a plurality of types of rear end side members 420, 421, 422, and a decorative portion 43 a. One ring-shaped member 43 is provided. Plural types of front end side members 410, 411, and 412 have different weights and / or outer peripheral structures, and plural types of rear end side members 420, 421, and 422 have different weights and / or outer peripheral structure. ing. For example, when different weights are used, the plurality of types of tip side members 410, 411, and 412 may use materials having different specific gravities, or may have different weights due to different axial lengths and outer diameters. Also good. Further, the difference in the structure of the outer peripheral portion can be, for example, a difference in the shape of the groove formed in the distal end side members 410, 411, 412, a difference in structure, a taper shape, or the like. In FIG. 3, only three types of front end side members and rear end side members are illustrated, but the number of front end side members and rear end side members in the dart barrel component set S is not particularly limited.

  According to the dart barrel component set S described above, by forming one ring-shaped member 43 having a decorative portion 43a of a predetermined design, the ring-shaped member 43 can be used for trial throwing as described above. By doing so, it becomes easy to manufacture the dart barrel 4 of different weight balance and total weight. In addition, depending on the design (shape, outer diameter, protrusion amount, etc.) of the decorative portion 43a of the ring-shaped member 43, it is possible to use an appropriate finger-hook rear end side member or the like.
