Description

  The present invention relates to an outer frame of a pachinko machine.

  Generally, a pachinko machine has a front frame and an outer frame, and the front frame is attached to the outer frame so as to be openable and closable (turnable). A game board or the like is attached to the front frame, and the game board is provided with a variety of winning holes, an accessory (center accessory) and the like. Various parts such as a control device and a pachinko ball supply device are provided on the back side of the game board.

The outer frame has a rectangular frame shape as a whole, and is formed by combining a pair of upper and lower horizontal frame members and a pair of left and right vertical frame members.
The pachinko machine (outer frame) is attached to each section (also referred to as “island”) provided on the attachment wall portion in the pachinko hall.

  The conventional general outer frame is made of wood. That is, the horizontal frame material and the vertical frame material are made of wood (the materials accompanying the horizontal frame material and the vertical frame material may be wood and others).

By the way, in recent years, an accessory (center accessory) provided on a game board has become large, and accordingly, various parts provided on the back side of the game board have also become large. For this reason, the inner dimension (especially the width direction) of an outer frame needs to be enlarged correspondingly.
On the other hand, the size of each section in the pachinko hall is set to a predetermined size.
For this reason, it is required that the width of the outer frame (particularly the vertical frame member) be reduced (the thickness is reduced).
On the other hand, the outer frame needs to have a predetermined strength or more.

For this reason, Patent Document 1 discloses a technical idea that the outer frame is formed of a metal material.
However, when the outer frame is simply formed of a metal material, the weight increases, and the attaching operation to each section of the pachinko hall becomes complicated.
JP 2004-188065 A

  An object of the present invention is to increase the inner dimension (distance between both vertical frame members) in the width direction of the outer frame of a pachinko machine and to reduce the weight thereof.

  In order to achieve the above object, the invention according to claim 1 is an outer frame of a pachinko machine having a substantially rectangular shape, and a front frame to which a game board is attached is rotatably attached around one edge thereof. A pair of upper and lower horizontal frame members extending in a substantially horizontal direction is formed of a wood material, and a pair of left and right vertical frame members extending in a substantially vertical direction is formed of a metal material.

  The “rectangular shape” includes a rectangular shape and a square shape.

In the outer frame of the pachinko machine according to the present invention, the vertical frame member is formed of a metal material. Therefore, the vertical frame member is narrower while maintaining a predetermined strength as compared with the case of being formed of wood. Can be formed. For this reason, the inner dimension (distance between both vertical frame members) in the width direction of the outer frame can be increased accordingly.
At the same time, in the outer frame of the pachinko machine of the present invention, since the horizontal frame material is made of a wood material, the weight of the outer frame is reduced compared to the case where the horizontal frame material is also formed of a metal material. It is done.
For this reason, in this outer frame, the efficiency of the attachment operation | work with respect to each division of a pachinko hall improves.

Further, since the horizontal frame member is formed of a wooden material, the outer frame can be easily and reliably attached to the wooden horizontal member of each section of the pachinko hall by a nail.
In other words, when the horizontal frame material is formed of a metal material, it is necessary to form holes for the nails to penetrate in advance at predetermined positions. The nail is locked at a predetermined position of the cross member. Then, when the outer frame (pachinko machine) is replaced and attached to each section of the pachinko hall many times, the nail is locked and removed many times at the same position on the cross member. Will be repeated, and the locking force of the nail will be attenuated.
However, in the outer frame of the pachinko machine according to the present invention, the horizontal frame member is made of a wood material. Therefore, when the outer frame (horizontal frame member) is attached to each section of the pachinko hall with a nail, the position differs for each attachment. The nail can be struck, and by doing so, the nail is locked at a different position in the cross member of each section, and the locking force of the nail is not attenuated.

  The invention according to claim 2 is the outer frame of the pachinko machine of the invention according to claim 1, wherein the vertical frame member is formed of a hollow metal material.

In the outer frame of the pachinko machine of the present invention, in addition to the operational effects of the outer frame of the pachinko machine of the invention according to claim 1, the following operational effects are obtained.
That is, in this outer frame, since the vertical frame member is formed not by a solid metal but by a hollow metal, the weight can be reduced accordingly.
For this reason, in this outer frame, the efficiency of the attaching operation to each section of the pachinko hall is further improved.

  The invention according to claim 3 is the outer frame of the pachinko machine of the invention according to claim 2, wherein the vertical frame member is an outer frame of the pachinko machine formed by joining two metal plates. is there.

In the outer frame of the pachinko machine of the present invention, in addition to the operational effects of the outer frame of the pachinko machine of the invention according to claim 2, the following operational effects are obtained.
That is, in this outer frame, the vertical frame member is formed by joining two metal plates, and thus can easily be made hollow.

  As described above, in the outer frame of the pachinko machine of the present invention, the inner dimension in the width direction (distance between both vertical frame members) can be increased, and the weight can be reduced. The efficiency of installation work for the compartment is improved.

Next, an embodiment of the present invention will be described based on the drawings.
As shown in FIG. 1, the pachinko machine has a front frame 100 and an outer frame 10. The front frame 100 is attached to the outer frame 10 so as to be displaceable between a closed position and an open position.

The front frame 100 is provided with a game board (not shown). Various parts (all not shown) such as a large number of nails, windmills, various winning holes, and a center accessory are attached to the game board.

In the right vertical frame member 30b, the screw holes 43 and 53 are formed in the upper part thereof. In the left vertical frame member 30a, screw holes 43 and 53 are formed in the lower part thereof.

Thus, as shown in FIG. 4, there is a space between the main body portion 41 of the outer vertical frame member 40 and the main body portion 51 of the inner vertical frame member 50 in almost all portions of the vertical frame members 30a and 30b. ing.
However, as shown in FIG. 3, the portion around the screw hole 43 of the outer vertical frame member 40 protrudes inward (that is, toward the inner vertical frame member 50), and the outer vertical frame member is in that portion. The main body portion 41 (FIG. 4) 40 is in contact with the main body portion 51 (FIG. 4) of the inner vertical frame member 50 (not shown).

As described above, the vertical frame members 30a and 30b are formed hollow.
And while the outer surface in the width direction (the width direction of the pachinko machine) of each vertical frame member 30a, 30b has a planar shape extending in the vertical direction and the depth direction, the inner surface in the width direction is vertical. In addition, it is a stepped surface that is gradually displaced inward as it goes from the near side to the far side.

As shown in FIG. 3, the pair of horizontal frame members 20a, 20b and the pair of vertical frame members 30a, 30b are coupled as follows.
Coupling fittings 70 are used corresponding to the four corners of the rectangular outer frame 10. The coupling fitting 70 is formed by bending a metal plate at a right angle, and has a substantially horizontal plate portion 72 and a substantially vertical plate portion 76. A screw hole 73 is formed in the substantially horizontal plate portion 72. Screw holes 77 are also formed in the substantially vertical plate portion 76.

On the upper surfaces of the left and right end portions of the upper horizontal frame member 20a, a stepped portion 22 that is recessed corresponding to the substantially horizontal plate portion 72 of the coupling fitting 70 is formed. Similarly, step portions (not shown) are also formed on the lower surfaces of the left and right end portions of the lower horizontal frame member 20b.
The upper end portion and the lower end portion of the inner vertical frame member 50 are bent at right angles to the inner direction to form a substantially horizontal portion 32.
Screw holes 23 and 33 are formed in the step portion 22 of each horizontal frame member 20a, 20b and the substantially horizontal portion 32 of each inner vertical frame member 50. The screw holes 23 and 33 correspond to the screw holes 73 of the substantially horizontal plate portion 72 of the coupling fitting 70.

A cutout portion 26 is formed at each of the left and right ends of each horizontal frame member 20a, 20b corresponding to the substantially vertical plate portion 76 of the coupling fitting 70.
In the upper part and the lower part of the outer vertical frame member 40, corresponding to the substantially vertical plate part 76 of the coupling fitting 70, a recessed part 46 that is recessed inward is formed.
A screw hole 47 is formed in the recess 46 corresponding to the screw hole 77 of the substantially vertical plate portion 76 of the coupling fitting 70.

Then, a screw (illustrated) is passed through a screw hole 73 in a substantially horizontal plate portion 72 of the coupling fitting 70, a screw hole 23 in a step portion 22 in the horizontal frame members 20a and 20b, and a screw hole 33 in a substantially horizontal portion 32 of the inner vertical frame member 50. Are omitted).
In addition, a screw (not shown) is screwed through a screw hole 77 of the substantially vertical plate portion 76 of the joint metal fitting 70 and a screw hole 47 of the hollow portion 46 of the outer vertical frame member 40, thereby connecting the metal fitting 70 (substantially vertical plate). Part 76) and the outer vertical frame member 40 are joined together.
Regarding the upper coupling fitting 70, the upper screw (both not shown) of the two screws in the substantially vertical plate portion 76 is further screwed into the notch 26 of the horizontal frame member 20a. . Similarly, for the lower coupling fitting 70, the lower screw (not shown) of the two screws in the substantially vertical plate portion 76 is further screwed into the notch 26 of the horizontal frame member 20b.

In this way, the horizontal frame members 20a and 20b and the vertical frame members 30a and 30b are coupled to each other via the coupling fitting 70.

A shaft fitting 80 is provided at the lower left portion of the outer frame 10.
The shaft fitting 80 has a substantially horizontal portion 81 and a substantially vertical portion 82. A rotation support shaft 84 is formed on the substantially horizontal portion 81.
A screw hole 83 is formed in the substantially vertical portion 82. The aforementioned screws (not shown) that connect the left outer vertical frame member 40 and the left inner vertical frame member 50 are further screwed into the screw holes 83. Thus, the shaft fitting 80 (its substantially vertical portion 82) is coupled to the left vertical frame member 30a.
The substantially horizontal portion 81 is supported by the front plate member 28 of the lower horizontal frame member 20b.

  As shown in FIGS. 1 to 3, a shaft hole forming portion 85 is provided in the upper left coupling fitting 70 among the four coupling fittings 70 arranged corresponding to the four corners of the outer frame 10. . The shaft hole forming portion 85 extends to the near side from the substantially horizontal plate portion 72 of the coupling fitting 70, and the shaft hole 86 is formed in the shaft hole forming portion 85.

On the other hand, as shown in FIG. 1, a shaft hole fitting 110 is fixed to the lower left part of the front frame 100 (the lower left part in a state where the front frame 100 is located at the closed position; the same applies hereinafter). A shaft hole 114 is formed in the metal fitting 110. A rotation support shaft 84 is rotatably inserted into the shaft hole 114.
A shaft bracket 115 is fixed to the upper left portion of the front frame 100, and a pivot shaft 116 is formed on the shaft bracket 115. The rotation shaft 116 is inserted into the shaft hole 86 so as to be rotatable.
Thus, the front frame 100 is attached to the outer frame 10 so as to be rotatable about the left edge of the front frame 100 and the outer frame 10. The front frame 100 is displaced between a closed position that matches the outer frame 10 and an open position that does not match the outer frame 10.
A sliding metal fitting 29 is fixed to the upper end portion of the front plate member 28 of the horizontal frame member 20b below the outer frame 10, and the above-described front frame 100 is smoothly displaced.

As shown in FIGS. 2 and 3, the vertical frame member 30 b on the right side of the outer frame 10 is provided with a pair of locked members 90 in the vertical direction.
The locked member 90 has a plate-shaped mounted portion 91 and a locked portion 93. The attached portion 91 extends in the depth direction of the pachinko machine in its transverse section, and the locked portion 93 extends in the width direction of the pachinko machine in its transverse section. A screw hole 92 (FIG. 4B) is formed in the attached portion 91.
As shown in FIGS. 3 and 4B, a pair of slits 68 and 69 are formed in the upper and lower portions of the right inner vertical frame member 50, respectively. And the to-be-latched part 93 is inserted in the slit 69 from the outer side of the inner vertical frame member 50, and a screw (not shown in FIG. 4B) is inserted through the slit 68 from the inner side of the inner vertical frame member 50. The locked member 90 is fixed to the right inner vertical frame member 50 by being screwed into the screw hole 92 of the mounted portion 91.

As shown in FIG. 1, a pair of locking members 120 are provided on the right side of the front frame 100 in the vertical direction. Each locking member 120 can be displaced between a locking position (not shown) and a non-locking position (not shown).
Then, in a state where the front frame 100 is positioned at the closed position, the locking member 120 (located at the locking position) is locked to each locked member 90 (FIG. 2), whereby the front frame 100 is closed. Maintained. When the locking member 120 is displaced to the non-locking position, the front frame 100 can be displaced to the open position.

As shown in FIGS. 1 and 2, the pachinko machine (outer frame 10) is attached to each section of the pachinko hall as follows.
In a state before the front frame 100 is attached to the outer frame 10, the nail N is struck from the lower side against the upper horizontal frame member 20 a, and the nail N (the portion on the tip end side) is the horizontal frame member. It is locked to a wooden upper cross member (not shown) that penetrates 20a and forms each section.
Similarly, a nail N is struck from the upper side to the lower horizontal frame member 20b, and the nail N penetrates the horizontal frame member 20b to form each compartment (not shown). Is locked against.
After the outer frame 10 is attached to each section in this way, the front frame 100 is attached to the outer frame 10.

Next, the operation and effect of the outer frame 10 will be described.
In the outer frame 10, the vertical frame members 30a and 30b are formed of metal, and the horizontal frame members 20a and 20b are formed of wood.
For this reason, the vertical frame members 30a and 30b can be formed narrower while maintaining a predetermined strength as compared with the case of being formed of wood. For this reason, the inner dimension in the width direction of the outer frame 10 (the distance between the two vertical frame members 30a and 30b) can be increased accordingly.

Further, since the vertical frame members 30a and 30b are formed of a hollow metal instead of a solid metal, the weight can be reduced accordingly.
Since the vertical frame members 30a and 30b are each formed by joining two plate members (the outer vertical frame member 40 and the inner vertical frame member 50), they can be easily made hollow. At the same time, in the right vertical frame member 30b, the locked member 90 is attached to the inner vertical frame member 50 before the outer vertical frame member 40 and the inner vertical frame member 50 are joined together. The member 90 can be easily attached to the vertical frame member 30b without the attached portion 91 being exposed and unsightly.
Moreover, since the inner surface (inner vertical frame member 50) of the vertical frame members 30a and 30b is a stepped surface, a greater strength can be obtained than in the case of a planar shape. From this, the inner dimension in the width direction of the outer frame 10 can be increased accordingly.

  Further, since the horizontal frame members 20a and 20b are made of wood, the weight can be reduced compared to the case where the horizontal frame members 20a and 20b are also formed of metal. At the same time, as described above with reference to FIGS. 1 and 2, the outer frame 10 can be easily attached to each section of the pachinko hall by the nail N.

  Note that the above is merely an embodiment of the present invention, and it is needless to say that the present invention can be implemented in various modifications based on the knowledge of those skilled in the art.

  For example, the vertical frame members 30a and 30b are not necessarily formed by combining two plate members (the outer vertical plate member 40 and the inner vertical plate member 50), but may be formed integrally.
