Description

  The present invention relates to a hinge mechanism of a gaming machine in which an inner frame that covers the front surface of an outer frame is hinged to the outer frame so as to be swingable and openable.

  An example of the gaming machine is a pachinko machine. The pachinko machine includes, for example, an outer frame, a front frame that covers the front surface of the outer frame, and a glass frame that covers the front surface of the front frame. It is fixed to the installation frame base. The front frame (inner frame) is configured to be movable with respect to the outer frame (outer frame), and the glass frame (inner frame) with respect to the front frame (outer frame) is swingably opened by the hinge mechanism. A game board is accommodated on the rear side of the glass frame, and various game machines such as a prize opening and a prize winning device are arranged on the front side of the game board. A launch handle is provided on the front surface of the pachinko machine, and a game ball is launched toward the game area in accordance with the operation of the launch handle. The game ball launched into the game area falls along the game area, or wins a winning device or the like in the middle of the fall, so that the player can be entertained.

  While playing a game ball toward the game area and playing a game, there may be a problem that the game ball is clogged in the middle of the game area, for example. When such a malfunction occurs, the store clerk at the game hall uses a hinge mechanism to perform a service to eliminate the clogging of the ball by, for example, swinging and releasing the glass frame with respect to the front frame. On the other hand, when the glass frame is opened, a game ball in the game area may fall to the lower part of the front frame. Some game balls that have fallen to the lower part of the front frame do not fall outside the pachinko machine and remain on the lower part of the front frame. If a store clerk in the game hall closes the glass frame without noticing this, in some cases, a game ball may be sandwiched between the front frame and the glass frame, and the pachinko machine may be damaged. Therefore, a configuration has been proposed in which a game ball is dropped to the outside of the pachinko machine without stopping by providing an inclination at the lower part of the front frame (see, for example, Patent Documents 1 and 2).

  In addition, when the glass frame is opened with respect to the front frame, the game ball may drop and stop at the hinge mechanism portion that connects the glass frame to the front frame so as to be swingable. Therefore, FIG. 23 of Patent Document 2 discloses a configuration in which an inclination is provided in the hinge mechanism portion so that the game ball is dropped outside without stopping even in the hinge mechanism portion.

  Depending on the location of the ball clogging, the front frame may be swung open with respect to the outer frame to perform the clogging elimination work. There are times when it stops on the road. If the front frame is closed without noticing this, a game ball may be sandwiched between the outer frame and the front frame, and the pachinko machine may be damaged.

Therefore, when the intermediate first shaft hole 26 c is engaged with the intermediate first shaft portion 26 a and the intermediate portion fixing bracket 23 and the intermediate portion first swing bracket 33 are combined, the intermediate portion first swing bracket 33. An intermediate cover member 25 is in contact with the lower surface of the cover. As described above, since the intermediate cover member 25 is reliably brought into contact with the intermediate first swing metal fitting 33 by using the elastic force of the intermediate cover member 25, the electric charge accumulated in the glass frame 5 is reduced. Efficiently escape to the installation frame. The intermediate shaft portion 26 and the intermediate spacer 27 constitute a spacer shaft member in the claims.

  When assembling the intermediate portion fixing bracket 23, a shaft portion mounting hole (not shown) formed in the front portion of the support flat plate portion 24a and a shaft portion mounting hole (not shown) formed in the front portion 25a are intermediate. The shaft part 26 is inserted. Then, the intermediate spacer 27 is inserted into the intermediate shaft portion 26 from above, and the front plate 25a (intermediate cover member 25) is clamped and fastened by the support flat plate portion 24a and the intermediate spacer 27. In this manner, the intermediate cover member 25, the intermediate shaft portion 26, and the intermediate spacer 27 are integrally fixed to the intermediate metal fitting main body portion 24. The intermediate portion fixing bracket 23 is fixed to a slightly lower side of the left portion of the front frame, and a support flat plate portion 24 a protrudes forward with respect to the front frame main body portion 29. 7 and 8 exemplify a configuration in which a part of the upper surface of the front portion 25a is covered with the intermediate spacer 27. However, for example, a configuration in which the entire upper surface of the front portion 25a is covered with the intermediate spacer 27 is also illustrated. good.

As shown in FIG. 9, the intermediate first swing metal fitting 33 is formed to have a strength capable of supporting the glass frame 5, and has a flat support plate portion 33 a extending in the front-rear direction and the support plate. It is comprised from the attachment part 33b connected with the rear-end part of the part 33a, and extended up and down. An intermediate first shaft hole 33c is formed in the front portion of the support flat plate portion 33a. A swing stopper 33d extending downward is formed at the front end of the support flat plate portion 33a. A plurality of fixing holes 33e are formed in the attachment portion 33b, and a rivet, a screw, or the like is inserted into the fixing hole 33e, and the intermediate first swing metal fitting 33 is fixed to the glass frame main body portion 39. Is done.

  The intermediate part second swing metal fitting 43 is formed to have a strength capable of supporting the ball tray unit 6, and an intermediate second shaft hole that engages with the intermediate second shaft part 26 b is formed in the upper part thereof. Has been. The intermediate second swing metal fitting 43 is fixed to the upper left part of the ball pan main body 49 (see FIG. 2).

  With the frame upper hinge mechanism 10 and the frame lower hinge mechanism 20 having such a configuration, when the front frame 2 is swung about 45 degrees forward from the closed state with respect to the outer frame 1, the front frame 2 is positioned between the outer frame 1 and the outer frame 1. A gap is formed on the lower frame cover member 14 so that the game ball can fall. Further, when the front frame 2 is swung about 90 degrees forward from the closed state, the frame lower first swing metal fitting 22 does not come into contact with the frame lower cover member 14. Further, the front frame 2 is fully opened when it is swung about 135 degrees forward from the closed state, and is not swung further.

Further, the frame upper hinge mechanism 10 and the intermediate hinge mechanism 30 allow the glass frame 5 to be moved to the front frame 2.
On the other hand, a gap is formed on the intermediate cover member 25 where the game ball can be dropped between the front frame 2 and the front frame 2 when it is swung about 45 degrees forward from the closed state. Further, when the glass frame 5 is swung forward by about 90 degrees from the closed state, the intermediate first swing metal fitting 33 does not come into contact with the intermediate cover member 25. Further, the glass frame 5 is moved forward from the closed state by about 110.
When it is swung by ~ 120 degrees, it is in a fully open state and does not rock any further.

The configuration of the frame upper hinge mechanism 10, the frame lower hinge mechanism 20, and the intermediate hinge mechanism 30 has been described so far. In the following, while each frame is held in a closed state and used for a game, for example, a game ball stored in the ball storage tank 28 causes a ball clogging, and once the front frame 2 with respect to the outer frame 1 A case will be described in which an operation is performed in which the ball is clogged and opened to eliminate the clogging of the balls, and the closed state is maintained again.

  When such a ball clogging occurs, the game ball is not paid out from the ball payout device based on the winning state, and the player who notices this calls a sales hall clerk. The clerk of the game hall that has rushed uses the upper frame hinge mechanism 10 and the lower frame hinge mechanism 20 to eliminate the clogging of the ball, and swings the front frame 2 forward relative to the outer frame 1 to store the ball storage tank 28. To expose. Then, the exposed ball storage tank 28 is checked to eliminate the clogging of the ball, but the game ball of the ball storage tank 28 may drop toward the lower part of the outer frame 1 during the operation of eliminating the ball clogging. is there.

  In the conventional hinge mechanism, the frame lower cover member 14 is not provided with the frame lower fixing member 12 as in the present invention, so that the game ball dropped toward the frame lower fixing member may stop as it is. Therefore, if the front frame is swung and closed with respect to the outer frame without noticing this, it cannot be completely closed, or a pachinko ball is sandwiched between the outer frame and the front frame. The machine PM could be damaged.

  On the other hand, in the hinge mechanism according to the present invention, the frame lower fixing bracket 12 is provided with the frame lower cover member 14, and the rear portion of the frame lower fixing bracket 12 is covered with an inclined rear portion 14 b inclined forward. Since the front side portion of the frame lower bracket main body 13 with respect to the portion covered by the front portion 14a faces the lower surface of the front frame 2 regardless of the swing angle of the front frame 2, the frame lower fixing bracket 12 Most of the game balls that fall to the point fall to the portion of the inclined rear part 14b. Thus, by providing the inclined rear portion 14b at the portion where the game ball falls, the dropped game ball naturally rolls forward along the inclination, so that it can be reliably dropped outside the pachinko machine PM. Therefore, when the store clerk of the game hall swings the front frame 2 backward relative to the outer frame 1 and holds it in the closed state, it is confirmed whether or not the game ball is stopped on the lower frame fixing bracket 12. Even if the operation is forgotten, the game ball is not sandwiched between the outer frame 1 and the front frame 2, and the pachinko machine PM can be surely closed without being damaged.

  Up to this point, the case has been described in which the front frame 2 is swung and opened with respect to the outer frame 1 to eliminate the clogging of the balls, and the operation of holding the closed state again is performed. The ball clogging does not occur only in the ball storage tank 28 as described above, and may occur, for example, in the game area of the game board 9. In this case, it is necessary to carry out an operation of opening the glass frame 5 by swinging it with respect to the front frame 2 to eliminate the clogging of the balls and holding it again in the closed state. When this operation is performed, game balls in the game area may fall onto the intermediate part fixing bracket 23. Similar to the frame lower fixing bracket 12 described above, the intermediate fixing bracket 23 is also provided with an inclined rear portion 25b at a portion where the game ball falls, and the falling game ball naturally rolls forward along the inclination. It can be reliably dropped outside the pachinko machine PM. Therefore, when the store clerk of the game hall swings the glass frame 5 backward with respect to the front frame 2 and holds it in the closed state, it is confirmed whether or not the game ball is stopped on the intermediate fixing bracket 23. Even if the operation is forgotten, the game ball is not sandwiched between the front frame 2 and the glass frame 5, and the pachinko machine PM can be surely closed without being damaged.

  In the case of a configuration in which the hinge mechanism portion is inclined to prevent the stopping of the conventional game ball, a gap is created between the frames by this inclination, and illegal acts by inserting a piano wire or the like using this gap There was a risk of being performed. On the other hand, in the hinge mechanism according to the present invention, the frame lower cover member 12 is provided with the frame lower cover member 14, and the intermediate portion fixing member 23 is provided with the intermediate cover member 25, whereby the outer frame 1 and the front frame 2. The gap between the front frame 2 and the glass frame 5 can be closed. Therefore, it is possible to prevent the game ball that has fallen as described above from stopping and to effectively prevent an illegal act performed using the gap between the frames.

  As shown in FIGS. 10A and 10B, when the lower frame fixing bracket 12 and the lower frame first swing metal fitting 22 are combined, the front of the outer frame 1 is moved by the thickness of the lower frame spacer 16. A gap for smoothly swinging the frame 2 is formed, and the gap can be closed by positioning the frame lower cover member 14 between the gap. As shown in FIG. 11, when the intermediate fixing bracket 23 and the intermediate first swing metal fitting 33 are combined, the glass frame 5 is smoothly shaken with respect to the front frame 2 by the thickness of the intermediate spacer 27. A gap for movement is formed, and the gap can be closed by positioning the intermediate cover member 25 between the gaps. In particular, the bent edge portion 25d formed in the intermediate cover member 25 is effective against fraudulent acts performed using a gap from the left and right direction.

  In the above-described embodiment, the configuration in which the bent edge portions 25d are formed at the left and right end portions of the intermediate cover member 25 is illustrated, but the left and right end portions of the frame lower cover member 14 may be bent in the same manner as the intermediate cover member 25. . By doing so, it becomes possible to prevent illegal acts in the frame lower hinge mechanism 20 more effectively.

  Further, in the above-described embodiment, the frame lower cover member 14 comes into contact with the lower surface of the frame lower first swing metal fitting 22 and the intermediate cover member 25 is brought into contact with the lower surface of the intermediate first swing metal fitting 33 when being in the closed state. Although the configuration of contact is described, the present invention is not limited to this configuration. For example, the inclined rear portion 14b of the frame lower cover member 14 is inclined forward in a state where the inclined rear portion 14b is not in contact with the lower surface of the lower frame first swing metal fitting 22, and the inclined rear portion 25b of the intermediate cover member 25 is inclined to the intermediate portion first The structure may be inclined forward in the state of being close without contacting the lower surface of the moving fitting 33. When configured in this manner, regardless of the swing position of the front frame 2 relative to the outer frame 1 and the swing position of the glass frame 5 relative to the front frame 2, the frame lower cover member 14 and the inclined rear portion 25b are inclined forward. It has become. Therefore, even when the game ball falls with the front frame 2 or the glass frame 5 slightly swung, the game ball can be dropped to the outside of the pachinko machine PM.

  In the above-described embodiment, the frame lower cover member 12 is provided with the frame lower cover member 14 and the intermediate portion fixing bracket 23 is provided with the intermediate cover member 25. However, the present invention is not limited to this configuration. For example, a configuration in which a cover member is provided only on one of the frame lower fixing bracket 12 and the intermediate fixing bracket 23 may be employed.

  In the above-described embodiment, the frame lower cover member 14 and the intermediate cover member 25 formed of a thin metal plate having conductivity and elastically deformable are exemplified, but the present invention is not limited to this configuration. For example, the lower frame cover member 14 and the intermediate cover member 25 may be formed to be elastically deformable by using a resin material.

  In the above-described embodiment, the configuration in which the frame lower shaft portion 15 and the frame lower spacer 16 are formed of separate members has been described as an example. However, the present invention is not limited to this configuration. For example, a configuration using the frame lower spacer shaft member 81 in which the frame lower shaft portion 15 and the frame lower spacer 16 are integrated (see FIG. 3) may be used, thereby reducing the number of parts and reducing the manufacturing cost. it can. In the case of this configuration, the lower end shaft portion of the lower frame spacer shaft member 81 is press-fitted and fixed to the shaft portion mounting hole formed in the support flat plate portion 13a. Similarly, the intermediate shaft portion 26 and the intermediate spacer 27 may be configured to use an intermediate spacer shaft member 91 in which they are integrated (see FIG. 7). In the case of this configuration, the central shaft portion of the intermediate spacer shaft member 91 is press-fitted and fixed to the shaft portion mounting hole formed in the support flat plate portion 24a.
