Abstract
Description
[Technical field]
[0001] The present invention relates to indoor throwing sports equipment suitable for indoor sports. [Background technology]
[0002] There is a throwing sport called Mölkky that originated in Finland (Non-Patent Document 1). Players try to knock down wooden pins called skittles using wooden pins called mölkky. The target pins and the throwing pins are roughly the same size, and the target pins are marked with numbers from 1 to 12. The target pins are initially set up close together about 3-4 meters away from the throwing area, with the following arrangement: 1 / 2 in the first horizontal row, 3 / 10 / 4 in the second horizontal row, 5 / 11 / 12 / 6 in the third horizontal row, and 7 / 9 / 8 in the fourth horizontal row (Figure 8). Knocking down one pin gives a number of points equal to the number written on the pin. Knocking down two or more pins gives a number of points equal to the number of pins knocked down (for example, knocking down three pins gives three points). Pins that are leaning on the thrown pin (mölkky) or pins with numbers on them do not count (if they have fallen and have not landed completely on the ground, they do not count). After each throw, the pins are reset in the positions they were moved to. The first player to reach exactly 50 points wins. If the score exceeds 50, the score reverts to 25. If the player does not hit any of the target pins three times in a row, they are disqualified.
[0003] Such throwing competitions, known as mölkky, are mostly held outdoors. The target pins and throwing implements (called mölkky pins) are all made of wood, and there is no problem with using wood in outdoor competitions. However, in order to be able to play regardless of the weather and to make it easy for the elderly and disabled to enjoy, it is desirable to be able to play indoors, such as in a gymnasium. When playing indoors, wooden pins and throwing equipment may damage the floor, so equipment suitable for indoor play is desired. [Prior art documents] [Patent documents]

[0005] SUMMARY OF THE PRESENT EMBODIMENTS An object of the present invention is to provide indoor throwing sports equipment that is suitable for use in sports without damaging indoor floor surfaces. [Means for solving the problem]
[0006] In order to solve the above problems, the indoor throwing sports equipment of claim 1 is characterized in that the lower end side of a cylindrical or columnar sponge body is a perpendicular surface to the central axis and the upper end side is an inclined surface, a plurality of pins with weights attached are provided on the central axis, each pin has a different number written on the inclined surface, a throwing tool is provided with weights attached at symmetrical positions on the central axis of the cylindrical or columnar sponge body, and the plurality of pins and a single throwing tool are combined. The invention according to claim 2 has the center of gravity of the weight attached to the pin set on the upper side of the central axis. The invention according to claim 3 has covers provided on the end faces of the pin and the throwing tool. The invention according to claim 4 makes the position of the center of gravity of the pin variable. In the invention according to claim 5, the diameter of the bottom cover provided on the lower end surface of the pin is made smaller than the diameter of the sponge body. In the invention according to claim 6, the sponge body forming the pins and throwing implements is cylindrical. Effect of the Invention
[0007] According to the invention of claim 1, a cylindrical or columnar sponge body has a lower end perpendicular to the central axis and an upper end inclined, a plurality of pins with weights attached on the central axis, a different number written on the inclined surface of each pin, a throwing tool with weights attached at symmetrical positions on the central axis of the cylindrical or columnar sponge body, and the plurality of pins and a single throwing tool are combined, so that both the pins and the throwing tool are made of sponge. Therefore, even if the throwing tool is thrown or the pins fall, there is no risk of damaging the floor surface, and the game can be played safely indoors. According to the invention of claim 2, the center of gravity of the weight attached to the pin is set on the upper side of the central axis, so that the position of the center of gravity of the pin is higher than the center position in the vertical direction. This makes the pin more likely to fall over. According to the invention as defined in claim 3, the pins and the throwing tool are provided with covers on their respective end faces, improving their appearance. According to the invention of claim 4, since the position of the center of gravity of the pin is variable, the position of the center of gravity of the pin can be changed in the vertical direction, and the tendency of the pin to fall can be appropriately changed. According to the invention as defined in claim 5, since the diameter of the bottom cover provided on the lower end surface of the pin is smaller than the diameter of the sponge body, the pin becomes unstable and tends to fall over. According to the invention as defined in claim 6, the sponge body forming the pins and throwing implements is cylindrical. Therefore, cylindrical sponge bodies are available at low cost, and the manufacturing cost can be kept low. [Brief description of the drawings]

[0009] The present invention will be described in detail below with reference to the drawings. The indoor throwing equipment according to the present invention is a set of a plurality of pins 1 made of sponge and a single throwing tool 2 made of sponge.
[0010] The pin 1 has a cylindrical or columnar sponge body 3 (3a, 3b), the lower end side of the sponge body 3 forms a perpendicular surface 5 relative to a central axis 4, and the upper end side forms an inclined surface 6, with the number 7 written on the side of the inclined surface 6. In each drawing, the inclination angle of the inclined surface 6 is 45°, but this is not limited to this. A plurality of pins 1, specifically 12 pins, are provided, and each pin is labeled with a number from 1 to 12.
[0011] 1 and 2 show the case where a cylindrical sponge body 3a is used, with two weights 8 attached to the upper side on the central axis 4. The weights 8 may be metal balls, but spherical marbles (glass balls) are inexpensive and preferable. By using marbles 8 with a diameter larger than the inner diameter of the cylinder, the repulsive force of the sponge body 3a will hold the marbles 8 at a specified position on the central axis 4 inside the cylinder.
[0012] It is advisable to set the center of gravity of weight 8 attached to pin 1 on the upper side of central axis 4 when pin 1 is upright. The center of gravity of the weight will be the vertical midpoint of the attached weight. The upper side on central axis 4 means being located above midpoint 9 of central axis 4. By setting the center of gravity of weight 8 on the upper side of central axis 4, the position of the center of gravity of pin 1 becomes higher, making it easier for pin 1 to fall over. In addition, since the sponge body 3 is light, the center of gravity of the weight 8 and the center of gravity of the pin 1 are at substantially the same height.
[0013] By changing the mounting position of the weight 8, it is possible to raise or lower the center of gravity of the pin 1. If the mounting position of the weight 8 is made higher (Fig. 1(b)), the center of gravity of the pin 1 becomes higher, making the pin 1 easier to tip over. Conversely, if the mounting position of the weight 8 is made lower (Fig. 2(a)), the center of gravity of the pin 1 becomes lower, making the pin 1 harder to tip over. Furthermore, by varying the number of weights 8 attached, it is possible to raise or lower the position of the center of gravity of pin 1. Increasing the number of weights 8 in a higher position raises the position of the center of gravity of pin 1, making it easier for pin 1 to tip over. Conversely, increasing the number of weights 8 in a lower position (Figure 2(b)) lowers the position of the center of gravity of pin 1, making it harder for pin 1 to tip over. Depending on the player's situation, the center of gravity of the pin 1 can be adjusted higher or lower to make the pin 1 easier or harder to tip over, allowing the player to enjoy the game more.
[0014] The pin 1 has a cover 10 (10a, 10b) on the lower end surface 5 and the upper inclined surface 6. This covers the cylindrical hole and improves the appearance. The cover 10 (upper cover 10b) on the upper inclined surface 6 side has a number (7) written on it. The lid 10 (10a, 10b) is preferably provided detachably, so that the mounting position and number of the weights 8 can be easily changed.
[0015] Figures 3 to 5 show the case where a cylindrical sponge body 3b is used, in which the cylindrical sponge body 3b is divided into halves, a hole is dug at the position where the weight 8 is to be attached, the weight 8 is attached to the hole 11, and the halves are joined together to form a single unit. Regarding the variation (changing) of the center of gravity position in the case of the cylindrical sponge body 3b, Fig. 4 shows a case where weight attachment holes 11 are provided in three places and weights 8 are attached to two of the three places. By changing the attachment points, the center of gravity position can be changed. If weights 8 are attached to the top two places, the center of gravity of the pin 1 will be high (Fig. 4(a)), if they are attached to the bottom two places, it will be low (Fig. 4(b)), and if they are attached to the top and bottom two places, the center of gravity can be set to an intermediate position (Fig. 4(c)). FIG. 5 shows a case where weights 8 are attached to all three places, so that the center of gravity of the pin 1 is located in the middle position, but because it is heavier, it is less likely to tip over. In the case of the cylindrical sponge body 3b, the pin 1 is also provided with a lid body 10 (10a, 10b) on the lower end surface 5 and the inclined surface 6. This covers the dividing line between the lower end surface 5 and the inclined surface 6, improving the appearance. A number (7) is written on the lid body 10 (upper lid 10b) on the upper end inclined surface 6 side.
[0016] The lid 10 (bottom lid 10a) attached to the lower end surface of the pin 1 can be made smaller in diameter than the diameter (outer diameter) of the cylindrical or columnar sponge body 3 (FIG. 6). In this way, the pin becomes unstable and is more likely to fall over without shifting sideways.
[0017] The throwing tool 2 is provided with a cylindrical or columnar sponge body 12 (12a, 12b) and weights 8 attached at symmetrical positions on the central axis. The center of gravity is set in the center to maintain balance. Figure 7 shows the case where the cylindrical sponge body 12a is used, and Figure 8 shows the case where the columnar sponge body 12b is used. The weight of the throwing tool 2 can be varied by increasing or decreasing the number of weights 8. It is preferable that the weight can be varied according to the athlete's situation. The throwing tool 2, which is made of a cylindrical or columnar sponge body 12, is provided with a cover body 10 (side cover 10c) on the left and right end faces. This improves the appearance, just like the pin 1. It is preferable that the cover 10 (10c) is removable, which makes it easy to change the mounting position and number of the weights 8. If the cover 10 (10c) is cylindrical, it is necessary to form a weight mounting hole in advance.
[0018] Since both the pins 1 and the throwing tool 2 are made of sponge, even if the throwing tool 2 is thrown or the pins 1 fall over, the cushioning is high and the floor surface is not damaged, so that the game can be played safely even indoors. The lid 10 is made of a soft material that will not damage the floor surface.
[0019] When using cylindrical sponge bodies 3a, 12a, they can be obtained inexpensively, and the marbles 8 can also be obtained inexpensively. The attachment position of the marbles 8 can also be easily determined, so that the manufacturing cost can be kept low. When using cylindrical sponge bodies 3b, 12b, the work of dividing cylindrical sponge bodies 3b, 12b into halves and the work of forming a hole at the position where weight 8 is attached are time-consuming and tend to result in high costs.
[0020] As an example of dimensions, the pin 1 has a diameter of 65 mm, a height H of 150 mm, an inner diameter of the cylinder of 20 mm, and a diameter of the marble 8 of 25 mm, while the throwing tool 2 has a diameter of 65 mm, a length L of 220 mm, an inner diameter of the cylinder of 20 mm, and a diameter of the marble 8 of 25 mm, but of course the dimensions are not limited to these. Note that if the height H of the pin 1 is made higher (for example, 180 mm) and the center of gravity is also set higher, the pins will be easier to knock over.
[0021] Since the contestant throws the throwing tool 2 at the pin 1 to knock it down, if the center of gravity of the pin 1 is set high, the pin 1 can be knocked down easily without a strong force, and even weak people such as the elderly and the disabled can easily knock down the pin 1 and enjoy the game. Depending on the player's situation, the center of gravity of the pin 1 can be adjusted higher or lower to make the pin 1 easier or harder to tip over, allowing the player to enjoy the game more.
[0022] According to the indoor throwing sports equipment of the present invention, the sport can be played indoors, regardless of the weather or season, and even weak people such as the elderly and disabled can easily enjoy the sport. [Explanation of symbols]
