Description

  This project is mainly related to darts used in soft darts.

  There are two types of darts: hard darts and soft darts.

  Hard dart arrow (hereinafter referred to as hard dart) is a dart body with an arrow tip made of a metal needle that pierces a target (hereinafter referred to as a hard dart board) made by compressing hemp. A barrel portion, a shaft portion connecting the barrel portion and the flight portion, and a flight portion serving as a wing for stabilizing the way of flying the dart. It is used for a competition in which the hard dart is thrown and competed on a hard dart board.

  A soft dart arrow (hereinafter referred to as dart) is a resin arrow tip (hereinafter referred to as a chip) that pierces a target (hereinafter referred to as a soft dart board) to which numerous pores made of resin are applied. It consists of a barrel part that is the main body of the dart, a shaft part that connects the barrel part and the flight part, and a flight part that acts as a wing that stabilizes the flight of the dart. It is used for competitions in which the darts are thrown at a soft dart board.

  Barrels used in darts come in a variety of shapes, with varying weights and balances. The balance is roughly divided into the front center of gravity, the center of gravity, and the rear center of gravity, and the characteristics of how to fly when throwing a dart are different.

  In the case of a conventional dart barrel, the balance and weight of the barrel cannot be changed after purchase.

  FIG. 1 shows a conventional dart structure. The weight portion 12a of the barrel 12 of the dart 10 cannot be moved and changed. In order to easily change the balance of the dart 10 as a whole, the shaft 13 is changed to a material with a different specific gravity, for example, nylon resin, aluminum, titanium, etc., or the shaft 13 is changed to a longer or shorter one. Thus, although the balance of the entire dart 10 is to be changed, the balance is not greatly changed, and the center of gravity of the entire dart 10 cannot be changed forward (in the chip direction) from the center of gravity of the barrel 12 itself.

  For this reason, if you want to use a dart with a balance or weight that is different from the dart barrel that the user has, you must purchase it separately, which is costly.

  Also, if you like the shape of the barrel but want to change the balance or weight, you can buy it if it has the same shape but a different balance and weight, but you can use it without it. Absent.

  As a matter of fact, the barrels of darts with the same name and different weight from the same manufacturer will increase in length if they become heavier ・ The diameter of the circumference will become thicker, and if it becomes lighter, the length will become shorter ・ The diameter of the circumference will be thinner There is a tendency to become, and the appearance may change.

  Dart is a sport that uses nerves on the fingertips, so if the appearance of the part that touches the fingertips, such as the barrel, changes, the feeling of use due to the tactile sensation will change significantly.

  Therefore, the present invention can change the characteristics of how to fly by changing the balance and weight of the barrel at the user's will, keeping the feeling of use by touch without changing the appearance of the barrel of the dart. The object is to provide a dart having a structure.

  The present invention is a dart in which a hole 22a penetrating front and rear is provided in the barrel 22, and a columnar weight (hereinafter referred to as a weight) 25 is inserted into the through hole 22a.

  The dart is characterized in that a screw yama (female screw) is provided on the inner surface of the through hole 22a of the barrel 22 and a screw yama (male screw) is provided on the outer periphery of the weight 25.

  The weight 25 is provided with a groove 25a and is inserted into the through hole 22a of the barrel 22 using a screwdriver.

  By using a plurality of the weights 25, the weight 25 can be fixed at an arbitrary position by fastening the weights 25 to each other.

  The dart is characterized in that the balance and weight can be changed by inserting the weight 25 into the through hole 22a of the barrel 22 and setting the weight 25 at an arbitrary position intended by the user.

  Therefore, if the dart 20 of the present invention is used, various balances and weights can be set, and the balance and weight settings intended by the user can be realized without changing the darts used.

  The best mode for carrying out the present invention will be described below as an example.

  FIG. 1 is a structural diagram of a conventional dart as a comparative example. 2 to 7 show an embodiment of the present invention.

  The configuration of the dart 20 will be described. The dart 20 of the present invention includes a resin chip 21 to be inserted into a soft dart board, a barrel 22 which is a dart main body mainly supported by a fingertip, a weight 25 for adjusting the balance and weight of the dart, a barrel 22 and a flight 24. And a flight 24 that acts as a wing that stabilizes the way the darts fly.

  The barrel 22 is provided with a through hole 22a for inserting (screwing) the weight 25, and a screw yama (female screw) is provided on the inner surface of the through hole 22a.

  A screw yama (male screw) is provided on the outer periphery of the weight 25 and is inserted (screwed) into the through hole 22a of the barrel 22.

  The weight 25 is provided with a groove 25a, and is inserted (screwed) into the through hole 22a of the barrel 22 using a screwdriver. The groove 25a has a minus shape or a plus shape, and uses a screwdriver suitable for each.

  The balance of the dart 20 is changed to an arbitrary position of the user by inserting (screwing) the weight 25 into the through hole 22a of the barrel 22 to an arbitrary position of the user.

  As the weight 25, materials having different specific gravities may be used. For example, tungsten alloy, brass, stainless steel, aluminum, nylon resin, etc. Moreover, you may use combining the weight 25 of the material from which specific gravity differs.

  When one weight 25 is used as a weight, for example, a weight 25 made of nylon resin having a low specific gravity is used as a stopper to fix the position.

  As long as the weight 25 can be attached to the barrel 22 with the tip 21 and the shaft 23, any position and number of the user are used.

  Each figure will be described on the assumption that the weight 25 of the same material is used.

  FIG. 3 shows a state where the weight 25 is not used and is light in weight. The balance of the dart 20 is at the center of the barrel 22.

  FIG. 4 shows a state in which two weights 25 are used and arranged in the center of the through hole 22 a of the barrel 22. It is heavier than that of FIG. 3 and the balance of the dart 20 is in the middle of the barrel 22.

  FIG. 5 shows a state in which two weights 25 are used and arranged in front of the through hole 22 a of the barrel 22. It becomes heavier than that of FIG. 3 and the balance of the dart 20 is in front of the barrel 22.

  FIG. 6 shows a state in which two weights 25 are used and arranged behind the through hole 22 a of the barrel 22. Heavier than that of FIG. 3, the dart 20 balance is behind the barrel 22.

  FIG. 7 shows a state in which three weights 25 are used and arranged in the center of the through hole 22 a of the barrel 22. It is heavier than that of FIG. 4 and the balance of the dart 20 is in the middle of the barrel 22.

  As described above, by using the dart 20 of the present invention, various balances and weights intended by the user can be set. Therefore, there is no need to purchase a separate dart. Moreover, the characteristic with respect to how to fly can be changed by keeping the feeling of use by touch without changing an external appearance, and changing the balance and weight of the dart 20 by a user's intention.

  The prior art example, a weight part is a center center gravity center of a center, and a partial cross-section whole figure.   The Example of this invention, a partial cross-sectional exploded view.   The Example of this invention, the center gravity center in which weight is not used, and a partial cross section whole view.   The center of gravity of the embodiment of the present invention, the use of two weights, a partial cross-sectional overall view.   The embodiment of the present invention, the front center of gravity using two weights, and a partial cross-sectional overall view.   The embodiment of the present invention, the rear center of gravity using two weights, a partial cross-sectional overall view.   The center of the center of gravity of the embodiment of the present invention, using three weights, and a partial sectional general view.
