JP-A-8-243219 (FIG. 7)

  However, since the elastic rotator has a circular shape in cross section, the game ball rebounded by hitting the elastic rotator is rebounded at almost the same location, although it is rotating. For this reason, a game ball will collide with a specific obstacle nail intensively among the plurality of obstacle nails planted in the vicinity of the elastic rotating body. Accordingly, there is a problem that the wear of a plurality of obstacle nails varies, and the lifetime of only specific obstacle nails is shortened.

  An object of the present invention is to solve the above-described problems of the prior art and to provide a ball turning device for a pachinko gaming machine capable of enhancing the durability of a faulty nail around an elastic rotating body. .

  The ball return device of the pachinko gaming machine of the present invention is provided near the end of the outer rail of the inner and outer rails forming the game area, and when the game ball that has been launched collides, the game ball is moved inward of the game area. In a ball turning device of a pachinko gaming machine having an elastic rotating body that rotates at the same time as rebounding, the outer peripheral surface of the elastic rotating body has a polygonal cross section.

  According to this spherical turning device, since the elastic rotating body has a polygonal cross section, there are angular portions and flat portions on the outer peripheral surface thereof. Therefore, when the elastic rotator is rotating, the position of the angular portion and the angle of the plane portion are constantly changing, so that the game ball hitting the elastic rotator is less likely to rebound in a certain direction. Thereby, it is possible to disperse the rebounding game ball over a wide range, and it is possible to prevent intensive wear of only a specific obstacle nail.

  In addition, the ball turning device of the pachinko gaming machine according to the present invention is provided near the end of the outer rail of the inner and outer rails forming the game area, and when the launched game ball collides, the game ball is moved into the game area. In a ball turning device of a pachinko gaming machine having an elastic rotating body that rebounds and rotates at the same time, a large number of protrusions are provided on the outer peripheral surface of the elastic rotating body.

  According to this ball return device, when a game ball collides with the elastic rotator, the outer peripheral surface of the elastic rotator is uneven by the protrusions, so that the game ball hitting the elastic rotator is less likely to bounce in a certain direction. . Thereby, it is possible to disperse the rebounding game ball over a wide range, and it is possible to prevent intensive wear of only a specific obstacle nail.

  In addition, the ball turning device of the pachinko gaming machine according to the present invention is provided near the end of the outer rail of the inner and outer rails forming the game area, and when the launched game ball collides, the game ball is moved into the game area. In a ball turning device of a pachinko gaming machine having an elastic rotating body that rebounds and rotates at the same time, a groove is provided on the outer peripheral surface of the elastic rotating body.

  According to this ball return device, when a game ball collides with the elastic rotator, the outer peripheral surface of the elastic rotator is irregularly deformed due to the groove, so that the game ball that hits the elastic rotator is in a certain direction. It becomes difficult to rebound. Thereby, it is possible to disperse the rebounding game ball over a wide range, and it is possible to prevent intensive wear of only a specific obstacle nail.

  Here, the outer peripheral surface of the elastic rotator is configured to have a polygonal cross section, and a plurality of grooves of the elastic rotator are formed along the axial direction of the elastic rotator. In addition, the outer peripheral surface of the elastic rotator is configured to have a polygonal cross section, and a plurality of groove portions of the elastic rotator are formed in the circumferential direction of the outer peripheral surface of the elastic rotator. A plurality of the groove portions are formed so as to intersect each other in the circumferential direction and the axial direction of the elastic rotating body. Further, the groove is formed in a zigzag shape.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  The shaft 13 of the ball return device 9 is disposed substantially on the virtual extension line of the outer rail 1, and almost half of the elastic rotating body 16 belongs to the inside of the virtual extension line of the outer rail 1, that is, in the game area 4. ing. The shaft 13 of the ball return device 9 is arranged on the outer side of the virtual extension line of the outer rail 1 or on the outer side of the virtual extension line in order to reduce the impact when the game ball 6 collides with the elastic rotating body 16. Is preferable.

  The elastic rotator 16 has a double structure of an inner member 17 and an outer member 18 fixed to each other. The inner member 17 is made of a resin material such as polyacetal copolymer, and its inner peripheral surface 17a is a circumferential surface. The external material 18 is made of a rubber material in which vinyl synthetic resin or carbon is blended. The reason for this kind of material is to improve the wear resistance of the outer member 18 due to the collision of the game ball 6.

It is very different from the form. Since other configurations are basically the same as those of the first embodiment, description thereof will be omitted, and only different points will be described. That is, in the present embodiment, a plurality of (two in the present embodiment) groove portions 18b are formed in a zigzag shape on the outer peripheral surface 18a of the outer member 18 of the elastic rotor 16 along the circumferential direction. Yes. The reason why the groove portion 18b is formed in a zigzag shape is to increase the range for elastically deforming the outer peripheral surface 18a when the game ball 6 collides with the outer peripheral surface 18a of the elastic rotating body 16. In the present embodiment, a plurality of groove portions 18b are provided, but it is possible to change to a single groove portion 18b instead of a plurality of groove portions 18b. In this case, it is preferable to increase the zigzag folded width of the groove 18b.

  The outer peripheral surface 18a of the outer member 18 of the elastic rotator 16 according to the fourth embodiment shown in FIG. 7 has a regular octagonal cross section, and the configuration other than this is the same as that of the fourth embodiment. Therefore, the description here is omitted.

  The outer peripheral surface 18a of the outer member 18 of the elastic rotator 16 according to the fifth embodiment shown in FIG. 8 has a regular hexagonal cross section, and a large number of protrusions 18c are formed on the outer peripheral surface 18a. These protrusions 18 c are hemispherical and are integrally formed of the same material as the outer member 18. Here, four each are provided on each flat surface portion 18d delimited by the corners of the elastic rotator 16, and the projections 18c are arranged so as to be displaced from each other in the circumferential direction and the axial direction of the elastic rotator 16. Yes. In other words, the protrusions 18 c are scattered on the flat portions 18 d of the elastic rotator 16. The number of projections 18c in each flat surface portion 18d of the elastic rotator 16 can be 1 to 3 or 5 or more. When a plurality of projections 18c are provided, the arrangement of each projection 18c is arbitrarily set. It is possible to change.

  The outer peripheral surface 18a of the outer member 18 of the elastic rotator 16 according to the sixth embodiment shown in FIG. 9 has a regular octagonal cross section, and the rest of the configuration is the same as that of the fifth embodiment. Therefore, the description here is omitted.

  The outer peripheral surface 18a of the outer member 18 of the elastic rotator 16 according to the seventh embodiment shown in FIG. 10 has a circular cross-section, and the outer peripheral surface 18a of the outer member 18 has a large number at equal intervals in the circumferential direction. The groove portion 18b is formed. Each groove portion 18 b extends linearly along the axis of the elastic rotator 16 and has a predetermined depth toward the axis of the elastic rotator 16. In the present embodiment, as in the first embodiment, the depth of the groove portion 18b is set to such an extent that the inner bottom portion is located near the middle position of the thickness of the outer member 18.

  A plurality of (two in the present embodiment) groove portions 18b are formed in a zigzag shape on the outer peripheral surface 18a of the outer member 18 in the elastic rotor 16 along the circumferential direction. And each groove part 18b formed along the axial direction of the elastic rotating body 16 and each groove part 18b formed along the circumferential direction cross | intersect each other. The groove 18b extending in the circumferential direction of the elastic rotator 16 is set to the same depth as the groove 18b extending along the axial direction.

  The outer peripheral surface 18a of the outer member 18 of the elastic rotator 16 according to the eighth embodiment shown in FIG. 11 has a circular cross section, and the configuration other than this is the same as that of the fifth embodiment. Therefore, the description here is omitted.

  Next, operation | movement or an effect | action of each elastic rotary body 16 from 1st Embodiment to 8th Embodiment is demonstrated.

  When the game balls 6 rolling along the outer rail 1 by the operation of the handle 5 for the player's right-hand strike collide with the elastic rotors 16 according to the first to eighth embodiments, the elastic rotors The 16 outer members 18 repel the game ball 6 inward of the game area 4 due to its elasticity.

  In addition, since almost half of the elastic rotator 16 belongs to the game area 4, the game ball 6 rolling along the outer rail 1 is a part of the elastic rotator 16 belonging to the game area 4. The elastic rotator 16 collides and rotates counterclockwise around the shaft portion 13 as the center of rotation in the front view shown in FIGS.

  Here, since the outer peripheral surface of each elastic rotating body 16 according to the first to sixth embodiments, that is, the outer peripheral surface 18a of the outer member 18, is configured in a regular hexagonal cross section or a regular octagonal cross section, it was fired. The game ball 6 comes to collide with a flat rectangular portion 18d corresponding to each side of a regular hexagon or regular octagon, which is a component of the outer peripheral surface 18a of the elastic rotator 16. At this time, it can be said that the game ball 6 is not in point contact with the outer peripheral surface 18 a of the elastic rotating body 16 but in surface contact due to the elasticity of the elastic rotating body 16. The contact area of the game ball 6 with respect to the elastic rotator 16 is larger in the polygonal shape than in the case of colliding with the outer peripheral surface having a circular cross section, and the game sphere easily bites into the elastic rotator 16. Therefore, it is possible to increase the force for rotating the elastic rotator 16 compared to the case of colliding with the outer peripheral surface having a circular cross section as in the prior art, and the impact force received by the shaft portion 13 is weakened. It becomes possible to improve durability.

  In addition, the outer peripheral surface 18a of the elastic rotator 16 has an angular portion, and while the elastic rotator 16 is rotating, the angle at which the game ball 6 strikes the flat surface portion 18d constantly changes. The game ball 6 hitting the rotating body 16 is rebounded over a wide range. Therefore, the obstacle nail 10 is worn by repeating the collision of the game ball 6 with the obstacle nail 10, but it is possible to prevent only the specific obstacle nail 10 from being intensively worn.

  Moreover, since the outer peripheral surface 18a of each elastic rotator 16 according to the first to fourth embodiments has the groove 18b, the portion that forms the groove 18b when the launched game ball 6 collides. Is easily elastically deformed, and the game ball 6 is likely to bite into the outer peripheral surface 18 a of the elastic rotating body 16. Therefore, it is possible to increase the force for rotating the elastic rotator 16 compared to the case of colliding with the outer peripheral surface having a circular cross section as in the prior art, and the impact force received by the shaft portion 13 is weakened. It becomes possible to improve durability. In particular, since the groove 18b according to the first and second embodiments is formed at the corner of the elastic rotating body 16 where the impact force of the game ball 6 is concentrated, the portion where the groove 18b is formed is further elastically deformed. It becomes easy and the buffer effect with respect to the axial part 13 can be heightened further.

  Further, when the game ball 6 collides with the elastic rotator 16, the outer peripheral surface 18a of the outer member 18 is irregularly deformed due to the presence of the groove 18b, so that the game sphere 6 hitting the elastic rotator 16 rebounds over a wide range. be able to. Therefore, the obstacle nail 10 is worn by repeating the collision of the game ball 6 with the obstacle nail 10, but it is possible to prevent only the specific obstacle nail 10 from being intensively worn.

  Moreover, since the outer peripheral surface 18a of each elastic rotator 16 according to the fifth embodiment and the sixth embodiment has a large number of protrusions 18c, the launched game ball 6 is a protrusion of the elastic rotator 16. It is possible to increase the force for rotating the elastic rotator 16 as compared to the case of colliding with the outer peripheral surface having a circular cross section as in the prior art, and the impact force received by the shaft portion 13 as compared with the prior art. The durability of the shaft portion 13 can be improved. Moreover, since the outer peripheral surface 18a of the elastic rotator 16 is uneven due to the protrusion 18c, the game ball 6 hitting the elastic rotator 16 can be rebounded over a wide range. Therefore, the obstacle nail 10 is worn by repeating the collision of the game ball 6 with the obstacle nail 10, but it is possible to prevent only the specific obstacle nail 10 from being intensively worn.

  The elastic rotator 16 according to the seventh embodiment is different in configuration from the elastic rotator 16 according to the first to sixth embodiments in that the cross-sectional shape of the outer peripheral surface 18a is circular, but the outer peripheral surface 18a has a groove 18b similar to the elastic rotator 16 according to the first embodiment and the second embodiment, and a groove 18b similar to the elastic rotator 16 according to the third embodiment and the fourth embodiment. Therefore, when the launched game ball 6 collides, the part forming the groove 18b is elastically deformed, and the elastic rotating body 16 is more than the case where it collides with the outer peripheral surface having a circular cross section as in the prior art. It is possible to increase the force for rotating the shaft, weaken the impact force received by the shaft portion 13, and improve the durability of the shaft portion 13.

  The elastic rotating body 16 according to the eighth embodiment is different in configuration from the elastic rotating body 16 according to the first to sixth embodiments in that the cross-sectional shape of the outer peripheral surface 18a is circular, but the outer peripheral surface Since 18a has many projections 18c similar to the elastic rotator 16 according to the sixth embodiment and the seventh embodiment, the launched game ball 6 is placed on the projections 18c of the elastic rotator 16. It becomes possible to increase the force to rotate the elastic rotating body 16 compared to the case of colliding with the outer peripheral surface having a circular cross section as in the prior art, and the impact force received by the shaft portion 13 is weakened. The durability of the shaft portion 13 can be increased.

  In the third, fourth and seventh embodiments, since the groove 18b is formed in a zigzag shape, the outer peripheral surface 18a of the elastic rotating body 16 is easily elastically deformed when the game ball 6 collides. can do. Therefore, as described above, the impact force received by the shaft portion 13 can be weakened to further enhance the durability of the shaft portion 13, and the effect of preventing only the specific obstacle nail 10 from being intensively worn can be achieved. Can be further improved.

  The embodiment of the present invention may be modified as follows.

  In the third, fourth and tenth embodiments, the groove portion 18b extending in the axial direction of the elastic rotator 16 is formed linearly, but may be formed in a zigzag shape.

  The outer peripheral surface 18a of the elastic rotator 16 of the seventh embodiment shown in FIG. 10 may be changed to a polygonal shape.
