Description

  The present invention relates to a pachinko machine having a game board that is positioned by fitting between a boss receiving portion of a plate-like member and a boss portion of a base member.

  In recent years, for example, as disclosed in Patent Document 1, a pachinko machine in which at least a part of a game board is formed of a transparent synthetic resin has been devised. The game board disclosed in Patent Document 1 is configured by fixing a spacer to the rear surface of a plate-like member having a game area formed on the front surface. Here, regarding the fixation between the plate member and the spacer, a boss portion having a locking portion is provided on the front surface of the spacer, and a boss receiving portion capable of locking the boss portion is provided on the plate member. A configuration is adopted in which the plate-like member and the spacer are fixed by being locked to each other.

However, in the conventional game board, a problem may occur that the plate-like member is displaced with respect to the spacer due to a load caused by a collision of game balls.
Therefore, if the plate member and the spacer are to be firmly fixed in order to prevent the displacement, it is necessary to make the boss part and the boss receiving part more closely contact, that is, to increase the proximity.
However, when the plate-like member is thermally expanded due to a temperature rise, the shape change in the lateral direction of the plate-like member is hindered by increasing the proximity between the boss portion and the boss receiving portion. A problem that causes warping occurs.

And it is explanatory drawing which expanded and showed the insertion state with the boss receiving parts 71-73 corresponding to each boss | hub part.

The game board 10 includes a plate-like member 31 formed in a single plate shape, and a base member 32 that is fitted and fixed to the whole plate-like member 31 on the rear surface side of the plate-like member 31.
The plate-like member 31 is a transparent substantially circular plate-like body formed from acrylic resin, and a plurality of obstacle nails are planted on the front surface thereof. Further, the plate-like member 31 has boss receiving portions 71 to 73 for inserting the boss portions at positions corresponding to the boss portions 61 to 63 provided on the front surface of the base member 32 that contacts the rear surface side of the plate-like member 31. It has been drilled.

The base member 32 is formed of a synthetic resin (for example, polycarbonate) having higher heat resistance than the plate-like member 31. When viewed from the front, the base member 32 is formed at the upper left corner, the upper right corner, the lower left corner, and the lower right corner. Corresponding lattice members 51, 52, 53, and 54 are connected to each other. Each of the lattice members 51 to 54 has a lattice structure in which a rib piece having a height of approximately 12 mm protrudes from a bottom plate portion having a thickness of approximately 2 mm and is orthogonal to the vertical direction and the horizontal direction.
A concave fitting portion 33 having the same shape as the plate-like member 31 is formed on the inner peripheral edge on the front side of the base member 32 at a depth of about 9 mm from the surface. Furthermore, in the fitting part 33 of the base member 32, the boss | hub parts 61-63 are installed in three places toward the right direction from the outer rail 12 vicinity seeing from the front side.

Each has a convex portion that can be inserted into the concave portion of the lattice member 54. The upper right edge of the lattice member 52 is formed with a cutout for installing the game board 10 in the middle frame.

The lattice member 53 at the lower left corner has a substantially triangular shape similar to the lattice member 51, and a convex portion that can be fitted into the recess of the lattice member 51 is formed at the upper end portion in contact with the lattice member 51 at the upper left corner. Each of the right end portions in contact with the lattice member 54 has a convex portion that can be inserted into the concave portion of the lattice member 54.
Further, protrusions 80, 80... Are provided at regular intervals on the lower side of the fitting portion 33 formed on the front surface of the lattice member 53. The protrusions 80, 80,... Are formed such that the tip portion in contact with the plate-like member 31 is narrower and rounder than the base end portion, and when the plate-like member 31 is fitted into the base member 32, The plate-like member 31 can be supported by the tips of the projections 80, 80.
Further, of the three boss portions, the leftmost boss portion 61 is provided near the launch entrance of the outer rail 12 in the fitting portion 33 of the lattice member 53, and the central boss portion 62 is the boss portion 61. Is provided at a position spaced apart from the right by a predetermined distance (FIG. 5). Each boss part 61, 62 is formed by projecting rib pieces vertically and horizontally from a cylindrical shaft part, and the protruding amount of each rib piece varies depending on the position of the boss part. Temporarily, in the relationship between the boss portion and the boss receiving portion, the gap between the rib piece protruding in the left-right direction of the boss portion and the boss receiving portion is X, and the rib piece protruding in the vertical direction of the boss portion and the boss When the clearance between the receiving portion and the receiving portion is Y, in the leftmost boss portion 61, the left and right clearance X1 and the vertical clearance Y1 are both 0.15 mm (FIG. 6A). . Further, in the central boss portion 62, the gap Y2 between the rib piece projecting in the vertical direction and the boss receiving portion 72 is 0.15 mm, like the boss portion 61, but in the left-right direction. The gap X2 between the rib piece projecting from the boss and the boss receiving portion 72 is 0.5 mm (FIG. 6B).

The lattice member 54 at the lower right corner has a substantially triangular shape similar to the lattice member 51, and a recess is formed at the upper end portion in contact with the lattice member 52 at the upper right corner, and a recess is formed at the left end portion in contact with the lattice member 53 at the lower left corner. Respectively. Further, the lower right edge of the lattice member 54 is formed with a notch for installing the game board 10 in the middle frame.
Furthermore, the boss 63 at the right end of the three bosses is provided in the fitting part 33 of the lattice member 54 (FIG. 5). The boss portion 63 is configured in substantially the same shape as the boss portions 61 and 62, and the gap X3 between the rib piece projecting in the left-right direction and the boss receiving portion 73 is 0.7 mm ( FIG. 6 (c)). Further, the rib pieces projecting in the vertical direction are formed such that the tip shape is trapezoidal and the gap V between the tip corner and the boss receiving portion 73 is 0.7 mm or more. (FIG. 6 (d)). In this way, by changing the protruding amount of the rib pieces of the boss portions 61 to 63, the proximity to the boss receiving portions 71 to 73 is changed every time the installation position of the boss portions 61 to 63 is separated from the outer rail 12. It is configured to be smaller.
In addition, like the lattice member 53, hemispherical protrusions 80, 80,... Are provided at regular intervals on the lower side of the fitting portion 33 of the lattice member 54 as well.

And the ring-shaped base member 32 is formed by inserting each convex part in the corresponding recessed part and screwing and integrating the grid members 51-54.
In addition, a screw hole into which a screw (not shown) for fixing both of the lattice members 51 to 54 in a connected state can be inserted.

  The plate-like member 31 and the base member 32 configured as described above include a plurality of boss portions provided on the front surface of the base member 32 in addition to the fitting of the fitting portion 33 provided on the front surface of the base member 32. Positioning is performed by fitting 61 to 63 and boss receiving portions 71 to 73. Furthermore, the game board 10 can be formed by screwing the base member 32 with the plate-like member 31 at the overlapping portion.

(Effects of the pachinko machine of the embodiment)
According to the pachinko machine 1 according to the present embodiment as described above, the proximity of the boss receiving portions 71 to 73 formed in the plate-like member 31 and the boss portions 61 to 63 provided in the base member 32 is It changes according to the position where each is installed. That is, the relationship between the left and right rib pieces of the boss portion and the inner periphery of the boss receiving portion is such that the left end boss portion 61 and the boss receiving portion 71 are in very close contact with each other. There is a slight gap, and the boss portion 63 and the boss receiving portion 73 at the right end have a considerable clearance.
Therefore, when the plate-like member 31 according to the present invention is expanded by heat, the plate-like member 31 and the base member 32 are firmly fitted by the boss portion 61 and the boss receiving portion 71 on the left side of the front surface. Even in this case, the proximity of the right front bosses 62 and 63 and the boss receiving parts 72 and 73 is lower than that of the conventional game board fixing method, so that the plate-like member 31 moves to the right side due to expansion. As a result, the plate-like member 31 is unlikely to warp.

  In the gaming machine of the above embodiment, the boss 61 to 63 is adjusted so that the proximity between the boss 61 provided near the launch entrance of the rail member and the boss receiving portion 71 is the highest. Therefore, there is no deviation between the plate-like member 31 and the base member 32 in the vicinity of the launch entrance, and the accuracy when launching the game ball is stable.

  Further, in the boss portions 61 to 63 in the above embodiment, the boss portion 61 has the largest protrusion amount in the left-right direction of the rib piece from the columnar shaft portion, and then the boss portion 62 and the boss portion 63 have the smallest amount. It is adjusted so that. Therefore, in the left-right direction, the degree of proximity between each boss portion and the boss receiving portion can be made different, and the warpage of the game board in the left-right direction can be effectively suppressed. Furthermore, the boss portions 61 to 63 are adjusted in the amount of protrusion of the rib pieces in the vertical direction so that the degree of proximity to the boss receiving portion is high in all the boss portions, and ensure the function as positioning. Is also possible.

Furthermore, in the case of a game board of a type in which the plate member is fitted into the base member, if the conventional configuration is adopted, when the game board is installed in an upright state, the inner periphery of the recess of the base member and the plate shape When the game board tries to move in the lateral direction, the outer periphery of the member is grounded on the entire surface, and a large friction is generated.
However, in the gaming machine 10 in the present embodiment, the plate-like member 31 is in contact with the inner periphery of the concave portion of the base member 32 at the lower side by the protrusions 80, 80. Therefore, compared with the conventional case where the lower side of the plate-like member and the inner periphery of the recess of the base member are in contact with each other, the plate-like member 31 is moved rightward by thermal expansion in this embodiment. When the plate member 31 moves, the friction between the plate member 31 and the base member 32 does not occur so much and the movement of the plate member 31 to the right side due to the expansion is not hindered. As a result, the plate member 31 is unlikely to warp. .

(Change example of pachinko machine)
It should be noted that the configuration of the gaming machine of the present invention is not limited to the aspect of the above embodiment, and the configuration of the shape, structure, etc. of the boss portion, the boss receiving portion, or the protruding portion deviates from the gist of the present invention. It can change suitably in the range which does not.

  In the present embodiment, the base member constituting the game board adopts a form in which a concave portion into which the plate-like member is fitted is adopted, but is not limited thereto, and if it is a type fixed to the rear surface of the plate-like member, it is plate-like It may be the same shape as the member.

  For example, in the present embodiment, the boss portions 61 to 63 employ a cylindrical shaft portion in which rib pieces are formed in a cross shape (FIGS. 6A to 6C). It may be columnar or square. Furthermore, an elliptical shape can be adopted for the boss portion (FIG. 6E). In that case, it is necessary that the major axis of the ellipse be provided so as to be positioned in the vertical direction of the boss portion so that the vertical gap Y4 with the boss receiving portion becomes small.

  Further, in this embodiment, the same material as the base member 32 is used for the material of the boss portions 61 to 63, and it is integrally formed. However, it is possible to fix the material after the heat-resistant plastic is separately formed. is there. Furthermore, any of epoxy resins, phenol resins, melamine resins, urea resins and the like may be used.

  Furthermore, the number of the boss portions 61 to 63 and the boss receiving portions 71 to 73 is not limited to three. If the plate-like member 31 is not prevented from moving to the right side due to expansion and, as a result, the effect that the plate-like member 31 does not easily warp can be maintained, the number may be increased.

Then, when a plurality of boss portions are provided substantially in the horizontal direction as in this embodiment, the boss portion (near the launch entrance of the rail member) located at the left end of the game board is inserted into the reference boss portion (boss receiving portion). In other embodiments, this is not limited to this, but the reference boss is positioned at the right end or is not positioned on the end side. Part may be used as a reference. In addition, regarding the proximity relationship between the reference boss part and the other boss part, it is desirable to make the other boss part inversely proportional to the distance from the reference boss part to reduce the proximity in the left-right direction. Therefore, it is possible to cope with the widening of the space between the boss receiving portions generated when the plate-like member is thermally expanded / contracted.
However, as the boss receiving part facing the boss part away from the reference boss part is more susceptible to the positional deviation in the left-right direction when the plate-like member is thermally expanded or contracted, it is close as described above. By keeping the degree small, it is possible to avoid problems such as warping without disturbing the shape change of the plate-like member in the lateral direction.

  In this embodiment, the proximity of the boss part and the boss receiving part when a plurality of boss parts are provided in the substantially horizontal direction is described, but a plurality of boss parts are provided in the vertical direction. This is also applicable to cases where When a plurality of boss portions are provided in the substantially vertical direction, as in the case of the substantially horizontal direction described above, the proximity of the other boss portions in the vertical direction is made inversely proportional to the distance from the reference boss portion. By making it small, it is possible to cope with the widening of the interval in the vertical direction between the boss receiving portions that occurs when the plate-like member is thermally expanded and contracted. As a method of varying the proximity in the vertical direction, the protruding amount of the upper and lower rib pieces of each boss portion may be varied, or the boss portion obtained by rotating the boss portion of FIG. The degree of proximity may be different.

Further, the projections 80, 80,... Are not limited to the projections 80, 80,... Formed integrally with the base member 32 as in the above embodiment, but the projections 80, 80 formed separately. .., Etc., such as a method of adhering, may be a method in which protrusions are provided on the base member by other methods.
Further, the material of the projections 80, 80,... Does not need to be the same material (synthetic resin or the like) as the base member 32, and can be different from the material of the base member 32. In addition, when the material of the projections 80, 80... Is different from that of the base member 32, the material of the projections 80, 80. It is preferable to use a material that is unlikely to cause the occurrence of defects (that is, excluding elastic materials having a high coefficient of friction such as synthetic rubber and natural rubber).
By adopting such a configuration, when the plate-like member 31 expands in the lateral direction, the friction between the plate-like member 31 and the projections 80, 80. The movement is not suppressed, and distortion is not easily generated.

  Further, the projections 80, 80,... Are not limited to those provided with the projections at regular intervals as in the above-described embodiment, and the interval and arrangement of the projections and the number of projections are appropriately set as necessary. Can be changed. In addition, the shape of the protrusion may be hemispherical as in the above embodiment, but is not limited to this, and the shape of the protrusion is hemispherical at the tip of a square or triangular or cylindrical base. It is also possible to use a U-shaped one provided with a portion, which can be changed as necessary.
