Abstract

PROBLEM TO BE SOLVED: To provide a barrel for darts, which facilitates identification of a gripping position, which eliminates a sense of discomfort, and which can secure stability.SOLUTION: A barrel 3 is made of iron and steel. The barrel 3 is formed in a triangular shape that comprises an approximately flat upper surface and side surfaces constricted into an approximately triangular chevron shape from both ends of the upper surface. One groove 8 is formed at each of starting and terminal ends, and two grooves 8 are formed in a central part.

Description

  The present invention relates to a barrel which is a part of a dart, the chip, and a dart provided with the chip and the barrel.

  As shown in FIG. 14, in the conventional dart, the barrel has a shape in which tungsten is formed in an annular shape, and its start and end (both ends) are simply narrowed down. Therefore, when gripping, the structure is supported with the feeling of substantially point contact with three fingers. Therefore, in general, the position to be gripped cannot be specified, there is a sense of incongruity, there is no stability, and there is anxiety. In addition, it is thought that high scores can not be expected in the enjoyment of darts and competition. In addition, the structure of the chip made of resin is in widespread use from the viewpoint of risk cancellation and simplification. However, since it is made of resin, it has the same problems as the application of durability and the aforementioned annular formation of the barrel.

  As an example to solve this problem, it is optimal to change the barrel formation. Further, the following inventions and devices can be cited as documents that can ensure the durability of the chip.

  Document (1) has a structure in which the barrel of the dart described in Utility Model Registration No. 3116156 is hexagonal or octagonal. However, with a simple polygonal structure, the grip feeling can be improved, but improvements can still be considered. For example, with this structure, it is considered that a sense of incongruity remains and stability is not the same, and high scores are not necessarily expected in dart fun and competition.

  Document (2) has a structure in which the barrel of the dart shaft described in Utility Model Registration No. 3118732 is polygonal or elliptical. However, this device can also be improved in the same manner as document (1).

  Reference (3) includes a dart chip, a dart shaft, and a dart described in International Publication No. WO 2007/000983, in which a single groove or the like is formed in the chip, and the shaft (barrel) is polygonal or elliptical. It is a structure to be solved. However, this invention can also be improved in the same manner as in the document (1).

  In the figure, reference numeral 1 denotes a dart, which includes a chip 2, a barrel 3, and a flight 5 (blade).

  The barrel 3 includes the first dart 1 shown in FIGS. 1 to 5, the second dart 1-1 shown in FIGS. 7 to 9, and the third dart 1-shown in FIGS. 10 to 12. 2 etc. is a preferable example. Hereinafter, it demonstrates in order.

  The barrel 3 of the first dart 1 shown in FIGS. 1 to 5 is made of iron or steel in consideration of weight and quenching. The barrel 3 has a substantially barrel-shaped structure formed in a triangular shape, which is composed of a substantially flat upper surface 3a and side surfaces 3b and 3c which are converged in a substantially triangular mountain shape from both ends of the upper surface 3a. The start end 3d and the end end 3e are annular and have a converged structure with respect to the central portion 3f. The first dart 1 has a structure in which a metal material made of iron or steel is formed by quenching and a pigment is added to give various colors. Improve each person's preferences. In this barrel shape, since the index finger can make surface contact with the upper surface 3a and the thumb and middle finger can make surface contact with both side surfaces 3b and 3c, the desired three-point support can be ensured. As a result, the above-mentioned specification of the grip position, the sense of incongruity, and the securing of stability, the anxiety, and the enjoyment of darts and / or competitions, or high scores can be expected in competitions. , Etc. 6 and 7 in the figure indicate screw holes. Reference numeral 8 denotes a groove which is recessed in the direction of the outer peripheral surface of the barrel. In this example, a single groove 8 is formed at the starting end 3d and the terminal end 3e, and two grooves 8 are formed at the central portion 3f. . This groove 8 is non-slip.

  The barrel 3-1 of the second dart 1-1 shown in FIGS. 7 to 9 is substantially barrel-shaped (substantially barrel-shaped cover), like the barrel 3 of the first dart 1. The dart 1-1 in this example is an example of using the conventional dart 100 shown in FIG. 14 by covering it, and as a general rule, provided with a through hole 10 for covering the barrel 300 of the dart 100. It shall be made. And the external shape of the barrel 3-1 has the upper surface 3a and the both end side surfaces 3b, 3c. In this embodiment, the screw holes 6 and 7 are not provided in principle. Further, the conventional barrel 300 has an advantage that the thickness can be ensured, the gripper is excellent in sensation and there is no increase in weight, and there is no sense of discomfort overall. In some cases, metal can be used, but some effects are hindered. However, it is effective from the viewpoint of using the conventional dart 100. Others conform to the first dart 1.

  The barrel 3-2 of the third dart 1-2 shown in FIGS. 10 to 12 has a shape different from that of the barrel 3 of the first dart 1, and the external shape is a potato shape (potato type cover). However, the dart 1-2 of this example is an example of using the conventional dart 100 shown in FIG. 14 by covering it, and as a rule, provided with a through hole 10 for covering the barrel 300 of the dart 100. And made of resin. In this embodiment, the screw holes 6 and 7 are not provided in principle. Further, the conventional barrel 300 has an advantage that the thickness can be ensured, the gripper is excellent in sensation and there is no increase in weight, and there is no sense of discomfort overall. In some cases, metal can be used, but some effects are hindered. However, it is effective from the viewpoint of using the conventional dart 100. Others conform to the first dart 1.

  The chip 2 shown in FIG. 5 to FIG. 6-2 is made of resin, and in order to reinforce and / or secure weight, the pigment 11 and the wire 12 (metal, hard resin, hard rubber, wood) , Ceramic, etc.). The pigment 11 is mixed as a whole and is the same as the resin of the material or has a different color. Moreover, the wire 12 is provided in the whole of an axial direction, and is made the same as the resin of a raw material, or is made into a different color. In this example, a general-purpose resin is used as a material to ensure cost reduction and convenience. And, in use, it is considered effective for ensuring the support of the dart 1 and the like and ensuring the weight balance. In the figure, reference numeral 13 denotes a screw shaft that is screwed into the screw hole 6 of the barrel 3.

  The flight 5 includes a blade 5a and a shaft 5b. A screw shaft (not shown) provided on the shaft 5 b is screwed into the screw hole 7 of the barrel 3.

  Since the index finger is in surface contact with the barrel-shaped upper surface 3a and the side surfaces 3b and 3c facing downward are provided on the barrel 3 which is the main body of the dart 1, the state where the thumb and the middle finger are in surface contact can be secured. The target three-point support is secured. As a result, there is a feature that allows gripping without a sense of incongruity, and the above-mentioned specification of the grip position, ensuring stability, eliminating anxiety, enjoying darts and / or competitions, or high scores in competitions. Can be expected. Moreover, it is the structure formed in the outer peripheral surface direction of the barrel by forming one groove 8 at the start end 3d and the terminal end 3e and two grooves 8 at the central portion 3f. It is useful for preventing slipping, specifying the position of the handle and ensuring stability, and enjoying throwing in a calm state. In addition, by using the covering method and the characteristics of the resin, you can enjoy the competition without any metal allergies.

  Further, the chip 2 can enjoy danger avoidance, weight reduction, colorfulization, and the like by using an appropriate weight including the wire 12 and resin characteristics.
