(1) Configuration
Throwing device 1
The throwing device 1 is a device used in a throwing game that is thrown toward a target board and determines a score according to the position at which it is sucked on the target board. Here, the form of the target board is not particularly limited as long as it contains a magnetic substance. A punching metal layer provided with a large number of through holes for visually recognizing the display may be provided.

When thrown toward a target board by a player, the throwing instrument 1 can stick to the target board while standing upside down with respect to the target board. Here, the "inverted state" includes a state in which the axis of the throwing implement 1 is perpendicular to the surface of the target board (a state in which the front end surface 11, which will be described later, is in contact with the target board), as well as a state in which the axis of the throwing implement 1 is in contact with the target board. A state in which the angle is any angle other than 0 degrees with respect to the target board (for example, a state in which the slope 12 and the slope 32, which will be described later, are in contact with the target board) may be included.

The throwing instrument 1 comprises, for example, a cap portion 10, a magnet 20, a barrel axis 30, three barrel grips 40, a shaft 50 and a flight 60. The axial length of the throwing instrument 1 is, but not limited to, approximately 109.5 mm, for example.

cap portion 10
The cap portion 10 is an example of a holding portion (first holding portion) that holds the magnet 20, and is a substantially cylindrical resin member that opens toward the rear in the axial direction. The cap part 10 protects the magnet 20, and reduces impact and impact noise generated when the thrown throwing implement 1 comes into contact with the target board. The cap portion 10 has a front end surface 11 , an inclined surface 12 , side surfaces 13 and an opening 14 .

The front end surface 11 is a substantially circular surface arranged at the axially forward end of the cap portion 10 . The diameter of the front end surface 11 is, but not limited to, approximately 11.6 mm, for example. The front end surface 11 is an example of a surface that comes into contact with the target board when the throwing implement 1 stands still in an inverted state with respect to the target board.

The slope 12 is a surface that extends axially rearward from the front end surface 11 and that is not parallel or perpendicular to the axial direction. The slope 12 constitutes a part of a substantially conical surface of a substantially conical shape whose apex is on the axially forward side and whose bottom surface is centered on the axially rearward side. Note that the slope 12 may be a surface that comes into contact with the target board when the throwing implement 1 stands still in an inverted state with respect to the target board.

The side surface 13 extends axially rearward from the slope 12 and has a substantially cylindrical shape. The diameter of the top surface or bottom surface of the substantially circular column is, for example, about 15 mm, although not limited to this. A claw 13a is formed on the upper side of the side surface 13, and a claw 13b is formed on the lower side of the side surface 13 by two cutouts provided in the side surface 13, respectively. Each of the claws 13a and 13b has a shape projecting radially outward. The protruding portions of the claws 13a and 13b can be engaged with the through-holes 33a and 33b of the barrel axis 30 by elastically deforming with the portion connected to the side surface 13 as a base point. The cap portion 10 is fixed to the barrel axis 30 by engaging the claw 13a with the through hole 33a and engaging the claw 13b with the through hole 33b.

The opening 14 is formed on the rear side of the cap portion 10 in the axial direction. Opening 14 accommodates magnet 20 therein. Inside the opening 14, ribs 14a, 14b, 14c, 14d, 14e, and 14f protruding radially inward are formed at substantially equal intervals in the circumferential direction (separated at substantially equal angles). . The rib 14a is formed radially inside the claw 13a, and the rib 14b is formed radially inside the claw 13b. Ribs 14a, 14b, 14c, 14d, 14e, and 14f each contact magnet 20 in the radial direction. A bottom surface 14g is formed on the front side of the opening 14 in the axial direction. The bottom surface 14g fixes the magnet 20 in the axial direction by coming into contact with the magnet 20 from the front side in the axial direction.

magnet 20
The magnet 20 emits a magnetic force for fixing the throwing implement 1 to the target board. Although the composition of the magnet 20 is not particularly limited, it includes, for example, aluminum, nickel, cobalt, iron, tungsten, chromium, and neodymium. The magnet 20 has, for example, a substantially cylindrical shape that is easy to mold, and has a front end face 21 substantially perpendicular to the axial direction, a side face 22 substantially concentric in the axial direction, and a rear end face 23 substantially perpendicular to the axial direction. have Since the front end surface 21 is substantially parallel to the front end surface 11 of the cap portion 10 , it is possible to design the magnet 20 to be closer to the front end surface 11 . Also, since the side surface 22 is substantially parallel to the side surface 33 of the front end 30A of the barrel axis 30, it is possible to design the magnet 20 further away from the side surface 33 thereof. The diameter of the front end face 21 and the rear end face 23 is approximately 10 mm. The length of side 22 is approximately 6 mm. The diameters of the front end surface 21 and the rear end surface 23 are preferably smaller than the diameter of the front end surface 11 of the cap portion 10 .

The front end surface 21 of the magnet 20 contacts the bottom surface 14 g of the cap portion 10 , and the rear end surface 23 of the magnet 20 contacts the erected portion 31 a of the barrel axis 30 . Sides 22 of magnet 20 also contact ribs 14 a , 14 b , 14 c , 14 d , 14 e , and 14 f of cap portion 10 . Thereby, the magnet 20 is held by the cap portion 10 contacting the magnet 20 at the front in the axial direction and the barrel axis 30 contacting the magnet 20 at the rear in the axial direction. Therefore, the cap portion 10 and the barrel axis 30 can be made of, for example, different compositions or materials, increasing the degree of freedom in design. In addition, the area to protect the magnet 20 can be increased, and the dropping of the magnet 20 from the throwing implement 1 can be suppressed.

barrel axis 30
The barrel axis 30 is an example of a holding portion (second holding portion) that holds the magnet 20 . The barrel shaft center 30 is made of resin, for example, and has a front end portion 30A, a main shaft portion 30B, and a rear end portion 30C.

The front end portion 30A has a substantially columnar shape that opens forward in the axial direction. The front end portion 30A has an opening 31 , a slope 32 , a side surface 33 , a slope 34 and a rear end surface 35 .

The opening 31 is formed on the axially forward side of the front end portion 30A. A substantially columnar standing portion 31a is provided on the bottom surface of the opening 31 on the rear end side in the axial direction. The standing portion 31a fixes the magnet 20 in the axial direction by coming into contact with the magnet 20 from the rear side in the axial direction.

The slope 32 is a surface that extends axially forward from the side surface 33 and is not parallel or perpendicular to the axial direction. The slope 32 constitutes a part of a substantially conical surface of a substantially conical shape whose axis is the axial direction. This is the surface that can come into contact with the target board when the thrown throwing implement 1 rotates while contacting the target board. The kinetic energy of the thrown throwing implement 1 can be efficiently dispersed to the target board by the slope 32 coming into contact with the target board. Note that the slope 32 may be a surface that comes into contact with the target board when the throwing implement 1 stands still in an inverted state with respect to the target board.

The side surface 33 is a substantially concentric surface in the axial direction. A through hole 33a is formed on the upper side of the side surface 33, and a through hole 33b is formed on the lower side of the side surface 33, respectively. As described above, the claw 13a of the cap portion 10 is engaged with the through hole 33a, and the claw 13b of the cap portion 10 is engaged with the through hole 33b. Thereby, the barrel axis 30 is fixed to the cap portion 10 .

The slope 34 is a surface that extends axially rearward from the side surface 33 and is not parallel or perpendicular to the axial direction. The slope 34 constitutes a part of a substantially conical surface of a substantially conical shape with the apex on the rearward side in the axial direction and the center of the bottom surface on the forward side in the axial direction.

The rear end surface 35 is a surface that extends axially rearward from the inclined surface 34 and is not parallel or perpendicular to the axial direction. The slope 34 constitutes a part of a substantially conical surface of a substantially conical shape with the apex on the rearward side in the axial direction and the center of the bottom surface on the forward side in the axial direction. The apex angle of the approximate cone is more obtuse than the apex angle of the approximate cone associated with the slope 34 .

The main shaft portion 30B integrally extends axially rearward from the front end portion 30A and has a substantially hexagonal prism shape. The main shaft portion 30B is inserted through the through hole 42 of each barrel grip 40 . The main shaft portion 30B has a side surface 36 forming a side surface of a substantially hexagonal column.

The rear end portion 30C integrally extends axially rearward from the main shaft portion 30B and has a substantially cylindrical shape. The trailing end 30C has a threaded side 37 . The thread formed on the side surface 37 is screwed into the thread formed on the inner peripheral surface of the opening 71 of the shaft 50 . This fixes the barrel axis 30 to the shaft 50 .

In the barrel axis 30, as described above, the main shaft portion 30B and the rear end portion 30C integrally extend from the front end portion 30A. The solid has a shape in which the main shaft portion 30B and the rear end portion 30C protrude. As a result, for example, it is possible to prevent the magnet 20 from being accidentally swallowed by an infant or the like.

barrel grip 40
The barrel grip 40 is, for example, a resin member having a substantially cylindrical shape. The barrel grip 40 is formed with a substantially hexagonal prism-shaped through hole 42 through which the main shaft portion 30B and the rear end portion 30C of the barrel axis 30 are inserted. The main shaft portion 30B and the rear end portion 30C of the barrel shaft center 30 are inserted through each barrel grip 40, and the rear end portion 30C of the barrel shaft center 30 is fixed to the shaft 50, whereby each barrel grip 40 can be used for throwing. It is fixed in place on the instrument 1 .

A side surface 41 of each barrel grip 40 constitutes at least part of a grasping portion for a player to grasp. The side surface 41 is formed with a plurality of line-shaped concave/convex portions facing in the circumferential direction. As a result, the grip of the holding part becomes less slippery, and the ease of throwing is improved. In addition, the side surface 41 may have a substantially polygonal shape such as a substantially hexagonal shape in a cross-sectional view in a direction perpendicular to the axial direction.

For example, the player can select a barrel grip 40 that he/she likes from various styles and employ it in the throwing instrument 1 . Therefore, the player can customize the grip portion (barrel grip 40) of the throwing tool 1, and the entertainment of the throwing game is improved. In this embodiment, the throwing implement 1 is provided with three barrel grips 40, but the number of barrel grips 40 is not limited to three.

shaft 50
The shaft 50 is a resin member having a substantially cylindrical side surface 51, protrusions 51a and 51b extending axially rearward from the side surface 51, and an opening 52 opening axially forward. be. The flight 60 is sandwiched between the protrusions 51a and 51b by pushing the flight 60 between the protrusions 51a and 51b. Threads are formed on the inner peripheral surface of the opening 52 . The threads are screwable with threads formed on the side surface 37 of the rear end 30C of the barrel axis 30 . Thereby, the shaft 50 is fixed to the barrel axis 30 .

flight 60
The flight 60 is a member made of resin having four blades 61, 62, 63, and 64 each having a substantially trapezoidal shape. Each of the blades 61, 62, 63, and 64 is arranged at approximately equal intervals (at approximately equal angles) in the circumferential direction. In the assembly of the throwing device 1, the shaft 50 is arranged such that the projection 51a of the shaft 50 is arranged between the blades 61 and 64, and the projection 51b of the shaft 50 is arranged between the blades 62 and 63, respectively. sandwich the flight 60 .

Note that the cap portion 10, the barrel axis 30, the barrel grip 40, the shaft 50, and the flight 60 may each be made of any material other than resin.

(2) Operation Next, operation of the throwing implement 1 will be described with reference to FIG. FIG. 11 shows the vicinity of the front end in the axial direction of the throwing instrument 1 in the cross-sectional view of FIG. Symbol S shown in FIG. 11 denotes the side surface of the throwing instrument 1 (the side surface 33 of the front end portion 30A of the barrel axis 30) and the slope of the throwing instrument 1 (the slope 12 of the cap portion 10 and the front end portion 30A of the barrel axis 30). A plane S passing through the boundary with the slope 32) and substantially perpendicular to the axial direction is shown.

As described above, the throwing instrument 1 has an axially non-parallel or non-perpendicular slope (cap A bevel 12 of the portion 10 and a bevel 32 of the front end 30A of the barrel axis 30). Therefore, the throwing implement 1 can be easily rotated between a state in which the slope is in contact with the target board, and a state in which the throwing instrument 1 is lying down on the target board and a state in which it is inverted substantially vertically. . The throwing instrument 1 also includes a magnet 20 held at one end by a holding portion (the cap portion 10 and the barrel axis 30). Therefore, a rotational moment acts on the throwing implement 1 to rotate it from a state of lying on the target board to a state of being substantially vertically inverted. As described above, the throwing implement 1 is more likely to stand upside down with respect to the target board than when it does not have a slope.

In addition, in the throwing instrument 1, at least one of the cap portion 10 and the barrel axis 30 may be provided with a slope that is not parallel or perpendicular to the axial direction. This increases the degree of freedom in designing the throwing implement 1 . Also, in the throwing instrument 1 , slopes that are not parallel or perpendicular to the axial direction may be provided on both the cap portion 10 and the barrel axis 30 . This makes it easier to adjust the area of the slope.

The distance between the front end surface 11 of the cap portion 10 and the front end surface 21 of the magnet 20 is D1, and the distance between the side surface 33 of the front end portion 30A of the barrel axis 30 and the side surface 22 of the magnet 20 is D2. At this time, if D1 is smaller than D2, the end face of the throwing implement 1 is more strongly attracted to the target board than the side face. Furthermore, when D1 is smaller than D2, the distance between the magnet 20 and the target board when the throwing implement 1 is inverted substantially perpendicular to the target board is equal to the distance between the magnet 20 and the target board when the throwing implement 1 is lying down on the target board. and the distance from the target board. Therefore, compared to the state in which the throwing implement 1 is laid down on the target board, the state in which the throwing implement 1 is inverted substantially perpendicularly to the target board is more stable. As described above, when D1 is smaller than D2, the throwing implement 1 can be more easily turned upside down.

The angle formed by the slope of the throwing implement 1 and the surface (the front end surface 11) perpendicular to the axial direction of the throwing implement 1 is defined as θ. In this embodiment, θ is set to about 60 degrees. In the throwing device 1, the angle θ may be set arbitrarily, but from the viewpoint of the ease with which the throwing device 1 can stand upside down with respect to the target board, the range of the angle θ is about 45 to 75 degrees. is preferred, a range of about 50 to 70 degrees is more preferred, and a range of about 55 to 65 degrees is even more preferred.

[Modification]
In the above-described embodiment, the slopes (the slopes 12 and 32) are described as being part of a substantially conical surface (substantially straight in a cross-sectional view parallel to the axial direction). However, the shape of the slope may be any other shape. The slope may be formed including, for example, a plurality of surfaces having different angles with respect to the axial direction. This makes the rotation of the throwing implement 1 inverted with respect to the target board smoother. Also, the slope may be formed with a recess, for example. This can improve manufacturing costs by reducing the material in the throwing device, and can also make it easier to separate the magnets from the sides of the throwing device. Also, the slope may be formed with, for example, a convex portion. This makes the rotation of the throwing implement 1 inverted with respect to the target board smoother.

The embodiments described above are for facilitating understanding of the present invention, and are not intended to limit and interpret the present invention. Each element included in the embodiment and its arrangement, materials, conditions, shape, size, etc. are not limited to those illustrated and can be changed as appropriate. Also, it is possible to partially replace or combine the configurations shown in different embodiments.
