Below, the connection of the lattice members 51-54 is demonstrated using FIGS.
First, the convex portion 71 of the lattice member 51 and the concave portion 62 of the lattice member 52 are fitted, and screws are screwed into the overlapping screw holes 71a and 71a and the screw holes 62a and 62a. And Next, the convex portion 72 of the lattice member 52 and the concave portion 63 of the lattice member 53 are fitted, and screws are screwed into the overlapping screw holes 72a and 72a and the screw holes 63a and 63a. 53 is connected. Further, the concave portions 73 of the lattice member 53 and the convex portions 64 of the lattice member 54 are fitted, and screws are screwed into the overlapping screw holes 73a and 73a and the screw holes 64a and 64a. And

And the lattice member 51 and the lattice member 54 are connected via the following metal plate 18 unlike the connection of other lattice members.
The metal plate 18 has a width that is substantially the same as the convex portion 74 of the lattice member 54 and a vertical length that is approximately twice the length of the convex portion. As shown in FIG. 7A, the metal plate 18 is provided with two screw holes 18c, 18c and two screw positioning holes 18d, 18d. The upper two screw holes 18c, 18c The lower two positioning holes 18d and 18d are for screwing with the member 51, and are for screwing with the lattice member 54.

In connecting the lattice member 51 and the lattice member 54 via the metal plate 18, first, as shown in FIG. 7B, the metal plate 18 is extended from the convex portion 74 of the lattice member 54 to the recess 84. The metal plate 18 and the convex portion 74 are inserted into the concave portion 61 of the lattice member 51 together. Next, among the screw holes shown in FIG. 7C, first, the positioning holes 61 c and 61 c of the recess 61 and the screw holes 18 c and 18 c of the metal plate 18 are screwed, and the metal plate 18 is attached to the recess 61. . At this time, as shown in FIG. 8, since the tip of the screw is located in the notch 74e or the round hole 74f, the convex portion 74 is not screwed. Furthermore, the screw head is embedded from the surface of the lattice member 51 by the embedded portion provided in the positioning hole 61c.
Next, the positioning holes 18d and 18d of the metal plate 18 and the screw holes 84d and 84d of the recess 84 are screwed. Then, the lattice member 51 and the lattice member 54 are connected by the metal plate 18, and the base member 32 is integrally formed. Further, the recess 84 is formed slightly deeper than the thickness of the metal plate 18. At this time, since the screw is screwed into the screw holes 84d and 84d provided in the recess 84, the screw head is the lattice member 54. It will be in the state embedded from the surface of (Fig. 8).

 The lattice member 51 and the lattice member 54 of the present embodiment are connected via the metal plate 18, and the convex portion 74 fitted into the concave portion 61 is reinforced by the metal plate 18, so that the convex portion 74 can be formed thin. It becomes possible. Therefore, it is possible to reduce the space in the concave portion 61 into which the convex portion 74 is inserted and to form the rear surface of the concave portion 61 with a sufficient thickness to ensure the strength, and to reduce the thickness of the entire connecting portion. .

 Further, the convex portion 74 of the lattice member 54 does not need to be thick because the metal plate 18 reinforces it, and is thin in this embodiment. Therefore, if the metal plate 18 is screwed directly to the convex portion 74, the convex portion 74 may be damaged. Therefore, one end of the metal plate 18 is screwed to the concave portion 61 of the lattice member 51, and the other end is screwed to the groove 84 positioned at the base of the convex portion 74 instead of the convex portion 74 of the lattice member 54. . That is, since nothing is screwed to the convex portion 74 located in the concave portion 61, the lattice member 51 and the lattice member 54 can be connected without damaging the convex portion 74.

  Further, as shown in FIG. 8, the connecting portion of the lattice member 51 and the lattice member 54 of the present embodiment has a three-layer structure of the lattice member 51, the metal plate 18, and the lattice member 54 from the front side. The tip of the screw inserted through the positioning hole 61c is located in the notch 74e or the round hole 74f in the convex portion 74 and does not contact the convex portion 74 itself. It can be avoided from being damaged by screwing or screwing in of the screw.

  And since the connection part of the lattice member 51 and the lattice member 54 of a present Example is located in the insertion part which mounts the plate-shaped member 31, it is necessary to make the surface level. Therefore, in this connection part, the mortar-shaped embedding part which the diameter gradually became small toward the rear surface from the front surface was formed in the opening part of the positioning hole 61c of the recessed part 61 located in the front surface. In addition, since the diameter of the front side of the embedded part is larger than the diameter of the screw head, the screw head is embedded and does not protrude from the surface, so the surface of the connecting part becomes horizontal. Even if the plate-like member 31 is placed, it does not become glazed.

  In addition, the structure of the pachinko machine 1 of the present invention is not limited to the aspect of the above-described embodiment, and the configuration of the concave portion, the convex portion, the metal plate and the protrusions 80, 80,. It can change suitably in the range which does not deviate from the meaning of this invention.

  Further, in the present embodiment, the same material as the base member 32 is used for the material of the concave portion and the convex portion, and it is integrally formed. However, it is also possible to fix the material after the heat resistant plastic is separately formed. . Furthermore, any of epoxy resins, phenol resins, melamine resins, urea resins and the like may be used.

  In the present embodiment, the metal plate 18 is attached only to the connecting portion of the lattice member 51 and the lattice member 54. However, the present invention is not limited to this, and other connecting portions are connected via the metal plate 18. Thus, the thickness of the connecting portion can be reduced as in this embodiment.

  In the present embodiment, the screw holes in the lattice members 51 to 54 are all formed in a circular shape, but either one of the concave or convex screw holes is elongated in the insertion direction of the convex portion. You may form in. As a result, the area where the two screw holes overlap increases, so that when the two lattice members are fitted, the connection position of the lattice members can be somewhat adjusted. Therefore, even when the base member 32 is formed using a grid member having a slight deviation in dimensions due to a processing error at the time of molding each grid member or a shape change caused by a temperature change after molding, etc. Since the degree of connection between the members can be adjusted, the base member 32 can be formed in accordance with the standards for fitting the plate-like member 31 and attaching it to the middle frame.

  Also, when either one of the concave or convex screw holes is formed in an oval shape, an oval screw hole is provided on the concave side located on the outer side, and a circular screw is formed on the convex side located on the inner side. It is better to provide holes. Thereby, the head portion of the screw can contact the concave portion, and the shaft portion of the screw can be screwed into the screw hole on the convex portion side, so that the two lattice members can be firmly connected.

  Next, the case where one of the screw holes is formed in an oval shape in the connecting portion assisted by the metal member will be described below. If an oval screw hole is provided on the recess side at the connecting portion between the grid member 51 and the grid member 54 of the present embodiment, the positioning hole 61c provided in the recess 61 is formed in an oval shape. . In that case, in the positioning hole 61c among the overlapping positioning holes 61c and screw holes 18c, the connection state between the lattice member 51 and the metal plate 18 is adjusted, and the screw heads are attached. Further, in the screw hole 18c, the screw shaft portion is screwed together, and the plate member 51 and the metal member 18 are fixed. Furthermore, the positioning hole 61c is formed in a laterally long oval shape in which the screw head can be embedded, so that the plate-like member 31 can be stably placed on the connecting portion.

  On the other hand, when an oval screw hole is provided on the convex side, the screw hole 18d provided in the metal plate 18 is formed in an oval shape. In that case, of the overlapping screw hole 18d and screw hole 84d, in the screw hole 18d, the connection state between the metal plate 18 and the lattice member 54 is adjusted, and the screw head is attached. Moreover, in the screw hole 84d, the screw shaft portion is screwed together, and the metal member 18 and the plate-like member 54 are fixed. Further, when the screw hole 18d of the metal plate 18 is formed in an oval shape, even if the screw head is brought into contact with the screw hole 18d and tightened strongly, compared to the synthetic resin member, it is resistant to tightening and is not easily damaged. There are advantages.

  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 friction coefficient such as synthetic rubber and natural rubber). By adopting such a configuration, when the plate-like member 31 expands or contracts in the lateral direction, the plate-like member 31 has a lateral force caused by friction generated between the plate-like member 31 and the projections 80, 80. The movement in the direction is not suppressed, and distortion hardly occurs.

  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.
