Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a pachinko machine.
[0002]
[Prior art]
In general, a pachinko machine is roughly composed of an outer frame, a front frame, a game board, a mechanism board, and the like. The front frame has a pin-type bracket on one side of the front frame, while the outer frame has a bearing-type bracket on the top and bottom of the side. It is attached to the front so that it can be opened and closed. Further, a frame member is integrally formed or screwed on the rear surface of the front frame, and a game board is fitted in the frame member. The game board is detachable from the frame member, and is locked to the frame member (front frame) by a clamp fitting provided on the frame member.
[0003]
A clamp metal fitting has an action piece which presses the back of a game board, and a knob for manual operation, and switches a clamp position and an unclamp position with a knob. When the clamp fitting is at the clamp position, the knob piece nestle close to the side surface of the game board, and conversely, when the clamp fitting is at the unclamp position, the knob piece jumps up to the outside of the game board.
[0004]
By the way, when the front frame is in the closed position where it overlaps the front of the outer frame, there is almost no gap between the frame member and the outer frame. Therefore, when the front frame is in the closed position, the clamp fitting cannot be moved from the clamp position. For these reasons, conventional pachinko machines have been assembled in the order of first attaching the game board to the front frame and then attaching the front frame to the outer frame.
[0005]
[Problems to be solved by the invention]
The work for assembling the front frame to the outer frame in the conventional order was a heavy labor because the game board and the mechanism board were already attached and the front frame was very heavy. In addition, the work of assembling the front frame to the outer frame is made by inserting the pin of the pin-type bracket into the shaft hole of the bearing-type bracket, and at the same time almost two places at the top and bottom. There is also a problem that workability is extremely bad.
[0006]
The present invention has been made in view of the above, and an object thereof is to enable attachment of a game board in a state in which a front frame is attached to an outer frame.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides an outer frame that is framed in a rectangular shape with a frame member, a front frame that is detachably mounted on the front surface of the outer frame, and a game board that is detachably installed on the front frame. A clamp fitting for locking the game board to the front frame, and the clamp fitting has a knob for operation, and the knob is pivoted so that the knob is brought close to the side of the game board. Switching between the clamp position and the unclamp position where the knob jumps to the outside of the game board, and when the front frame is in the closed position overlapping the front of the outer frame, the unclamp position from the clamp position of the clamp fitting In the pachinko machine in which the pivoting track of the knob and the inner surface position of the frame material constituting the outer frame overlap each other, the front frame is opposed to the clamp fitting of the outer frame when the front frame is in the closed position. In the position, pick the clamp bracket To provide a pachinko machine provided with an operation window that allows the flip-up to the unclamped position.
[0008]
[Action]
If the operation window of the outer frame is used, the clamp fitting can be freely operated from the clamp position to the unclamp position with the front frame attached to the outer frame. Accordingly, the game board can be attached to the front frame after the front frame is preceded by the outer frame, and then the game board can be locked by operating the clamp fitting as it is.
[0009]

[0010]
As is well known, a pachinko machine is roughly composed of an outer frame 1, a front frame 2, a game board 3, a mechanism board 4, and the like.
[0011]
The outer frame 1 is made of wood or synthetic resin, and as shown in FIG. 1 and FIG. 2, the upper and lower frame members 1a and 1b and the left and right frame members 1c and 1d form a vertically elongated frame, A curtain 1e is stretched around the edge. The outer frame 1 is provided with bearing brackets 5 on the left side when viewed from the front, on the upper corner portion and on the upper surface of the curtain plate 1e. In addition, an operation window 1w for the clamp fitting 7 is provided through the frame members 1a, 1c, and 1d of the outer frame 1 at positions corresponding to the clamp fitting 7 described later. Although the illustrated operation window 1w is in the form of a through hole, it may be in the form of a U-shaped notch that opens to the front or rear edge of the frame members 1a, 1c, 1d. Note that such a form of the operation window 1w may or may not be unified for all the frame members 1a, 1c, and 1d. In the latter case, for example, one frame member 1a (1c, 1d) is penetrated. The operation window 1w in the form of a hole is provided, and the operation window 1w in the form of a notch is provided in the remaining frame material.
[0012]
The front frame 2 is made of wood or synthetic resin, and is installed on the front surface of the outer frame 1 with its lower end edge placed on the upper end surface of the curtain plate 1 e of the outer frame 1. The front frame 2 has a frame shape having a large window hole 2w, and the frame member 2a is fixed to the back surface so as to surround the window hole 2w (in the case where the front frame 2 is made of synthetic resin, it may be integrally molded). There is.) Further, pin type metal fittings 6 are attached to the front frame 2 at the upper and lower corners on the left side when viewed from the front, and pins (not shown) of the pin type metal fittings 6 are provided on the bearing type metal fitting 5 of the outer frame 1. It fits in a shaft hole (not shown). Therefore, the front frame 2 can be opened and closed with respect to the outer frame 1 around the pin of the pin-shaped metal fitting 6.
[0013]
The game board 3 is obtained by attaching a decorative board made of synthetic resin to the surface of the plywood board, and is fitted into the frame member 2a as shown in FIG. 6, and further as shown in FIG. Are locked by a plurality of (three) clamp fittings 7, 7, 7. The clamp fitting 7 has a hand-turning structure pivotally attached to a rotary shaft 8 protruding from the frame member 2a, and includes an operation knob 7a and an action piece 7b for clamping the back surface of the game board 3. Consists of. As shown in FIG. 3, the rotary shaft 8 has a stop nut 8 a at the top, and a compression spring 8 b is interposed between the stop nut 8 a and the clamp fitting 7 so as to press the game board 3. Always acts on the clamp fitting 7.
[0014]
The mechanism plate 4 is made of a synthetic resin, and includes a sphere tank 9 for a prize sphere, a prize sphere discharge device 10 that emits a prize sphere, a winning sphere set 11 for collecting winning spheres, and a winning sphere process for processing the winning sphere. The device 12 and the like are installed in an integrated manner. The mechanism plate 4 is attached to the frame member 2a of the front frame 2 so as to be freely opened and closed by two upper and lower hinges 13 and 13 in a state of being superimposed on the back surface of the game board 3.
[0015]
The hinge tool 13 is a combination of a hinge component 13a fixed to the frame member 2a side and a hinge component 13b fixed to the mechanism plate 4 side. The hinge component 13a of the frame member 2a is formed in a screw-fixing base plate 13c that contacts the frame member 2a, a bearing plate 13d bent up at a right angle from the base plate 13c, and the bearing plate 13d. And a notch 13f reaching the shaft hole 13e at the rear part of the base plate 13c (the side facing the mechanism plate 4). The notch 13f has a tapered shape that spreads outward.
[0016]
On the other hand, the hinge component 13b of the mechanism plate 4 includes a screw-fixing base plate 13g that comes into contact with the mechanism plate 4, a shaft support plate 13h bent up at a right angle from the base plate 13g, and a downwardly facing downward toward the shaft support plate 13h. And a projecting pin 13j. The pin 13j of the hinge component 13b has a stepped structure in which the proximal end portion 13j0 and the distal end portion 13j1 have different thicknesses, and the diameter of the proximal end portion 13j0 is substantially equal to the shaft hole 13e, and the diameter of the distal end portion 13j1. Is substantially equal to the maximum width of the notch 13f. The length of the base end portion 13j0 of the pin 13j is set to be slightly longer than the thickness of the shaft support plate 13h. In the completed state of the pachinko machine, the base end portion 13j0 of the pin 13j of the hinge component 13b of the mechanism plate 4 is fitted into the shaft hole 13e of the hinge component 13a of the frame member 2a so as to be rotatably joined. The shaft hole 13e is provided with a notch 13f. However, since the diameter of the base end part 13j0 of the pin 13j is larger than the notch 13f, it cannot be removed.
[0017]
Next, a method for manufacturing (assembling) the pachinko machine will be described. First, the pin type metal fitting 6 of the front frame 2 and the bearing type metal fitting 5 of the outer frame 1 are combined to attach the front frame 2 to the outer frame 1. At this stage, there is no game board 3 or mechanism board 4 in the front frame 2, and only a few parts such as the launching device 14 and the speaker 15 (see FIG. 1) are attached. Mounting to 1 is also easy. At this time, it is necessary to rotate the clamp fittings 7 and 7 corresponding to the frame members 1a and 1c to the clamp position of the two-dot chain line in FIG. Otherwise, since the knob 7a of the clamp fitting 7 hits the point P of the outer frame 1 shown in FIG. 2, the frame member 2a does not enter the outer frame 1. However, when the operation window 1w is formed in a U-shape that opens to the front edges of the frame members 1a and 1c, there is no possibility that the clamp fitting 7 will collide even at the unclamping position. There is no hassle to rotate one by one. On the other hand, since the remaining clamp fitting 7 corresponding to the frame member 1d is near the center of rotation of the front frame 2, the knob 7a moves so as to go around the front edge of the frame member 1d. Therefore, the clamp fitting 7 corresponding to the frame member 1d has a clamp position because the knob 7a wraps around the front edge of the frame member 1d and jumps directly into the operation window 1w even if the operation window 1w has a through-hole shape. There is no need to rotate it.
[0018]
Next, a finger is inserted through the operation window 1w of the outer frame 1, and the entire clamp fitting 7 is turned to the unclamp position as shown by the solid line in FIG. Incidentally, since the conventional pachinko machine does not have such an operation window 1w, there is no room for rotation of the clamp fitting 7 under the situation where the frame member 2a is surrounded by the outer frame 1. Therefore, in the conventional pachinko machine, the game board 3 is installed on the front frame 2 and then the front frame 2 is assembled to the outer frame 1.
[0019]
Next, the game board 3 is fitted into the frame member 2a, a finger is inserted from the operation window 1w, and the knob 7a of the clamp fitting 7 is pushed and turned, so that all the clamp fittings 7 are rotated to the clamp position of the two-dot chain line in FIG. Let After that, it is desirable to close the used operation window 1w by fitting and bonding a lid member 1x made of wood or synthetic resin as shown by a one-dot chain line in FIG.
[0020]
In addition, when the used operation window 1w is closed with the lid member 1x as described above, it is effective in preventing the clamping metal fitting 7 from being forgotten to be tightened in a regular replacement work of the game board 3 or the like. That is, if the operation window 1w has a U-shape that opens to the front edge of the outer frame 1, if the used operation window 1w is closed with the lid member 1x, even if the clamp fitting 7 is forgotten to be tightened The knob 7a collides with the lid member 1x and the front frame 2 is not tightened. In addition, when the operation window 1w is in the form of a through hole or a U-shape that opens to the rear edge of the outer frame 1, as described above, the clamp fittings 7 and 7 corresponding to the frame members 1a and 1c Although there is no risk of forgetting to tighten regardless of the presence or absence of the lid member 1x because it collides with the point P of the frame 1, the remaining clamp fitting 7 corresponding to the frame member 1d wraps around the front edge of the frame member 1d as described above. Since there is no cover member 1x, there is a possibility that the knob 7a jumps directly into the operation window 1w and does not notice that it is forgotten to tighten. On the other hand, if the operation window 1w of the frame member 1d is closed with the lid member 1x, the knob 7a of the clamp metal fitting 7 hits the rear lid member 1x that wraps around the front edge of the frame member 1d, and stops. You will definitely notice that you forgot to tighten. Of course, it is free to close the operation window 1w of the frame members 1a and 1c with the lid member 1x.
[0021]
Next, the hinge component 13a of the frame member 2a and the hinge component 13b of the mechanism plate 4 are joined, and the mechanism plate 4 is mounted on the back surface of the front frame 2. That is, the tip 13j1 of the pin 13j of the hinge component 13b (position as close to the base end 13j0 as possible) is fitted into the notch 13f of the hinge component 13a, and is pushed into the front frame 2 as it is. Then, since the tip end portion 13j1 of the pin 13j passes through the notch portion 13f and enters the shaft hole 13e, the mechanism plate 4 is slightly lowered to fit the base end portion 13j0 of the pin 13j and the shaft hole 13e. In this case, the mechanism plate 4 is moved down in the outer frame 1, but the movement amount for that purpose is very small. And the mechanism board 4 with which the front frame 2 was mounted | worn is fixed with the well-known locking device 16,16 .... In addition, if the frustum-shaped taper is formed in the step part of the base end part 13j0 and the front-end | tip part 13j1 of the said pin 13j, the base end part 13j0 will fit smoothly with respect to the axial hole 13e.
[0022]
As described above, the mechanism plate 4 of the present embodiment is moved in the direction perpendicular to the back surface of the front frame 2 with respect to the front frame 2 as assembled to the outer frame 1, and the hinge components 13a and 13b of the hinge device 13 are connected to each other. However, once installed, the mechanism plate 4 can be opened and closed around the hinge 13 as before, and the front frame 2 is opened to open the mechanism plate 4. If lifted, the pin 13j of the hinge component 13b comes out of the shaft hole 13e of the hinge component 13a, so that the mechanism plate 4 can be attached and detached in a conventional manner.
[0023]
FIG. 7 shows another embodiment of the hinge device 13, wherein the pin 13j of the hinge component 13b of the mechanism plate 4 has a uniform round bar shape, while the hinge component 13a of the frame member 2a has elasticity. A metal or synthetic resin is formed in a substantially Ω shape. The hinge 13 can be easily joined by simply pressing the pin 13j against the opening of the hinge component 13a, and the mechanism plate 4 does not have to be moved down when the hinge components 13a and 13b are joined. There is.
[0024]
8 (a) and 8 (b) show another embodiment of the hinge device 13, in which the hinge component 13a of the front frame 2 is divided into a base portion 13a1 having a U-shaped groove 13a0 and a bifurcated portion at the tip. There is a feature in that it has a combined structure with a lock piece 13a3 having a locking portion 13a2. In this hinge component 13a, after the pin 13j of the hinge component 13b is fitted into the U-shaped groove 13a0, the lock piece 13a3 is inserted into the U-shaped groove 13a0 and coupled to the hinge component 13b. The locking portion 13a2 of the lock piece 13a3 engages with the locking hole 13a4 on the side surface of the U-shaped groove 13a0 in a so-called fitted-off state, and once fitted, it does not come off. However, the lock piece 13a3 does not hinder the vertical insertion / removal operation of the pin 13j.
[0025]
In the embodiment described above with reference to FIGS. 1 to 8, the hinge tool is provided with a laterally-joining means for joining the hinge components together in a direction substantially perpendicular to the back surface of the front frame, thereby achieving the purpose. is there.
[0026]
On the other hand, in FIGS. 9A and 9B, the hinge components 13a and 13b are joined and the hinge component 13b is screwed to the mechanism plate 4 in advance, and the hinge component 13a is attached to the frame member 2a (front frame). 2), the mechanism plate 4 is attached to the front frame 2 after being joined at the final stage. In this case, the base plate 13c of the hinge component 13a has a substantially U-shaped cross-section that fits over the upper surface of the frame member 2a, and is provided with locking claws 17 that bend inwardly at both end edges of two parallel pieces. is there. On the other hand, the frame member 2a is provided with a locking groove 18 that fits into the locking claw 17, and when the base plate 13c of the hinge component 13a is fitted on the frame member 2a, the frame member 2a shown in FIG. Thus, the locking claw 17 engages with the locking groove 18 and does not come off. Similarly, the hinge components 13a and 13b can be joined in advance, the hinge component 13a can be attached to the frame member 2a, and the hinge component 13b can be joined to the mechanism plate 4 at the final stage. .
[0027]
Although the embodiment of the invention has been described above, the above description discloses a new method of manufacturing (assembling) a pachinko machine that can improve the production efficiency by rearranging the assembly process of the conventional pachinko machine. That is, “attach the front frame to the front of the outer frame, then attach and lock the game board to the front frame with the front frame in the closed position, and then keep the front frame in the closed position. “A manufacturing method of a pachinko machine in which a mechanism plate is attached to a front frame”.
[0028]
【The invention's effect】
As described above, the pachinko machine of the present invention freely rotates the clamp fitting from the clamp position to the unclamp position with the front frame attached to the outer frame by using the operation window of the outer frame. Therefore, even after the front frame is attached to the outer frame, the game board can be attached and locked to the front frame. As a result, it is possible to replace the assembly line of the pachinko machine so that the process of assembling the front frame to the outer frame is executed before the process of attaching the game board to the front frame. The excellent effect of reducing the burden on production and greatly increasing production efficiency is demonstrated.
