Description

  The present invention belongs to the technical field of ball game machines.

  A ball game machine such as a pachinko machine has an outer frame that becomes an outer shell and is fixed to the island where the game machine is installed. An inner frame that holds the game board is arranged inside the outer frame, and a windowed frame having a window for facing the game board is arranged on the front side of the inner frame, and both the inner frame and the windowed frame are door-shaped. It is usually possible to open and close.

The outer frame is horizontally provided between the left and right vertical members arranged facing each other, the upper horizontal member horizontally provided between the upper ends of the left and right vertical members, and the lower ends of the left and right vertical members. A lower transverse member,
A technique is known in which the upper horizontal member constituting the outer frame is made of a wooden plate and one or both of the vertical members are made of an aluminum alloy, and the strength of the outer frame is increased or the weight is reduced.
JP 2008-61953 A

The connection between the upper horizontal member, which is a wooden board, and the vertical member, which is an extruded product of an aluminum alloy, is performed, for example, by screwing an angle-shaped connection fitting to both.
This angle-shaped connecting metal fitting may be arranged outside the corner or inside the corner. On the other hand, in both cases, the screw is screwed in from the outside to the inside.
(A) When the connecting metal fitting is arranged on the outside, the screw is screwed into the vertical member that is an extrusion molded product. However, sufficient bonding force cannot be obtained by itself, so a sheet metal part is arranged on the inside, It has been practiced to screw the tip of a screw penetrating the member.
(B) When the connecting bracket is arranged on the inside, the screw head presses the upper horizontal member, which is a plate material, so that the screw head prevents the upper horizontal member, which is a plate material, from being recessed. In order to prevent this, it was necessary to take measures such as using seated screws and washers.

  Needless to say, in the case of (a), measures such as using a seated screw are unnecessary, and in the case of (b), it is not necessary to arrange a sheet metal part inside. That is, both (a) and (b) have advantages and disadvantages.

The outer frame of the ball game machine according to claim 1 is:
Left and right vertical members arranged facing each other;
An upper horizontal member horizontally disposed between upper ends of the left and right vertical members;
In an outer frame of a ball game machine comprising a lower horizontal member horizontally disposed between lower end portions of the left and right vertical members,
At least one of the vertical members is an aluminum alloy extruded product and has a plate shape, and the upper horizontal member is a wood plate,
In order to connect the vertical member of the extrusion molded product and the upper horizontal member, a connecting sheet metal screwed to both is,
An outer surface abutting portion that abuts against an outer surface of the upper transverse member from an upper surface to an end surface of the upper transverse member;
An inner surface abutting portion that abuts on the inner surface of the longitudinal member of the extruded product;
It is characterized by comprising an intermediary portion that is sandwiched between the upper end surface of the vertical member of the extruded product and the upper horizontal member and connects the outer surface contact portion and the inner surface contact portion.

In the outer frame of the ball game machine according to claim 1, in order to connect the vertical member of the aluminum alloy extruded product and the upper horizontal member which is a plate material, the connecting sheet metal which is screwed to both is the upper horizontal member. An outer surface contact portion that contacts the outer surface of the upper horizontal member from the upper surface to the end surface, an inner surface contact portion that contacts the inner surface of the vertical member of the extruded product, and the upper end surface and upper horizontal member of the vertical member of the extruded product With an intermediary part that is sandwiched between the outer surface contact part and the inner surface contact part,
Since the outer surface contact part functions as a washer for the screw screwed into the upper horizontal member, it is not necessary to use a screw with a seat or a washer here.
Since the screw screwed into the vertical member of the aluminum alloy extruded product is screwed into the inner surface abutting portion, it is not necessary to provide a sheet metal part for screwing the screw.

[Example]
As shown in FIGS. 1 and 2, the outer frame (hereinafter also simply referred to as “outer frame”) 1 of the ball game machine of this embodiment is an extruded product of aluminum (more precisely, an aluminum alloy). The left vertical member 2 and the right vertical member 3 are provided. The left vertical member 2 and the right vertical member 3 are arranged facing each other.

  The left vertical member 2 and the right vertical member 3 are not accurate plate members as is apparent from the end face shape shown in FIG. 1B, but the width (the vertical dimension in FIGS. 1B and 1C) and Since the length (the vertical dimension in FIG. 1A and the horizontal dimension in FIG. 1C) both greatly exceeds the thickness (the horizontal dimension in FIGS. 1A and 1B), I can say that.

  Between the upper ends of the left and right vertical members 2 and 3, an upper horizontal member 5, which is a wooden board, is provided horizontally. Further, a lower horizontal member is provided between the lower ends of the left and right vertical members 2 and 3, but the illustration of the lower horizontal member is omitted.

An upper surface abutting portion 8 received by 6 is provided. The upper surface abutting portion 8 is shaped and dimensioned to substantially compensate for the cutting of the upper sheet metal receiving portion 6 and is provided with two screw holes 8a for screws. The upper horizontal member 5 is screwed by screws (not shown) inserted through the screw holes 8a. These screws pass through the upper horizontal member 5, and the tip portion is screwed into the screw receiving plate 15.

  An end surface contact portion 9 is connected to the upper surface contact portion 8, and the end surface contact portion 9 is brought into contact with the right end surface 10 of the upper horizontal member 5. An L-shaped portion composed of the upper surface contact portion 8 and the end surface contact portion 9 corresponds to the outer surface contact portion.

  A mediation portion 11 is connected to the lower end of the end surface contact portion 9. The mediating portion 11 is arranged in parallel with the upper surface contact portion 8, and the upper surface contact portion 8 and the end surface contact portion 9 form a U-shaped groove structure. On the other hand, a lower sheet metal receiving portion 12 is formed at the right end (lower side) of the upper horizontal member 5 by the same cutting process as the upper sheet metal receiving portion 6. As shown in the figure, the mediating portion 11 has a shape and dimensions that substantially compensate for the cutting of the lower sheet metal receiving portion 12.

  The upper end surface of the right vertical member 3 is abutted against the upper lateral member 5, but there is no gap between the butted portions as shown in the drawing (however, the lower sheet metal receiving portion 12 is excluded). Accordingly, the mediating portion 11 is received by the lower sheet metal receiving portion 12 and is sandwiched between the upper end surface of the right vertical member 3 and the upper horizontal member 5.

The upper sheet metal receiving portion 6 and the lower sheet metal receiving portion 12 are arranged in parallel, but the cut length from the end face 10 is different as shown in the figure.
An inner surface contact portion 13 is connected to the other end of the mediation portion 11. The inner surface contact portion 13 is suspended from the mediation portion 11 in a direction perpendicular to the mediation portion 11 and the upper surface contact portion 8 and parallel to the end surface contact portion 9.

  The inner surface abutting portion 13 is in contact with the inner surface of the right vertical member 3, but in the range where the inner surface abutting portion 13 abuts, the sloped protrusion 3 a formed inside the right vertical member 3 is cut off. It is almost flat.

  The inner surface contact portion 13 is provided with four screw pilot holes 13a, and screws (not shown) inserted into the four screw holes 3b provided in the right vertical member 3 are used for screws. By screwing into the lower hole 13a, the right vertical member 3 is screwed.

In this manner, the upper end portion of the right vertical member 3 and the upper horizontal member 5 are connected using the connecting sheet metal 7.
On the other hand, the left vertical member 2 and the upper horizontal member 5 are connected using an angle-shaped inner connection sheet metal 17 and a hinge holding member 18. The hinge holding member 18 is provided with a bearing portion 19 for holding a hinge shaft of an inner frame (not shown), and a bearing used for connecting the left vertical member 2 and the upper horizontal member 5 is a bearing. This is a portion excluding the portion 19.

  The inner connecting sheet metal 17 is arranged inside the connecting portion (corner) between the left vertical member 2 and the upper horizontal member 5, and the left vertical member 2 is a screw (penetrated through the left vertical member 2 ( (Not shown) are screwed into the screw holes 13a. This connection structure is the same as the connection by screwing between the inner surface contact portion 13 and the right vertical member 3.

  Further, the inner connecting metal plate 17, the upper horizontal member 5 and the hinge holding member 18 are inserted into four screw holes provided in the hinge holding member 18, penetrate the upper horizontal member 5, and the front end portion of the inner connecting metal plate 17. They are connected to each other by screws (not shown) screwed together. This connection structure is similar to the connection of the inner surface contact portion 13, the upper horizontal member 5, and the screw receiving plate 15.

  The outer frame 1 of the ball game machine according to the present embodiment includes left and right vertical members 2 and 3 that are arranged facing each other, and an upper horizontal member 5 that is horizontally disposed between upper ends of the left and right vertical members 2 and 3. And an outer frame 1 of a ball game machine comprising a lower horizontal member disposed between lower end portions of the left and right vertical members 2 and 3, wherein the vertical members 2 and 3 are made of an aluminum alloy extruded product. The upper horizontal member 5 is a wooden board, and the connecting sheet metal 7 screwed to the right vertical member 3 and the upper horizontal member 5 is connected to the upper surface contact portion 8 and the end surface contact portion. 9 and an outer surface abutting portion that contacts the outer surface of the upper horizontal member 5 from the upper sheet metal receiving portion 6 to the end surface 10 of the upper horizontal member 5 and the inner surface of the right vertical member 3.
