Description

  The present invention relates to a gaming machine in which when an inner frame pivotally attached to an outer frame is closed and locked, the inner frame can be smoothly locked.

  Conventionally, a pachinko gaming machine which is a type of gaming machine has the following configuration, for example. That is, in the pachinko gaming machine, an inner frame in which a game board is arranged on one side of the front surface of a rectangular frame-shaped outer frame is pivotally attached so as to be freely opened and closed. A locking device having a cylinder lock for locking or unlocking the inner frame is attached to the open side of the inner frame. On the upper and lower portions of the locking device, there are provided locking pieces that engage with locking pieces provided on the upper and lower portions of one side inner surface of the outer frame and lock the inner frame. More specifically, each lock piece is pivotally attached so that a hook part protruding backward from the locking device is always urged upward, and each hook part is engaged with each lock piece while rotating downward. Match.

Then, with the inner frame locked, the key inserted into the cylinder lock is operated to rotate the lock part of each lock piece downward, thereby disengaging each lock piece from each lock part. The inner frame is unlocked and can be opened to the front side. In addition, by pressing the closed inner frame toward the outer frame and closing it, the flange of each lock piece automatically engages with each lock piece while rotating downward against its bias. The inner frame is locked to the outer frame (see, for example, Patent Document 1).
Japanese Utility Model Publication No. 6-75574 (paragraph 0019, page 5-7, FIG. 1)

  By the way, in recent pachinko machines, the size of the variable display device mounted on the game board is conspicuous, and the inner frame in which the game board is arranged has a ball tank storing game balls on the back side thereof, etc. Many back parts are mounted, and the overall weight of the inner frame is considerably increased. However, since the inner frame is pivotally mounted on only one side thereof, when the inner frame is opened after unlocking, the open side tends to be lowered by its own weight. When the opening side of the inner frame is lowered and tilted in this way, the positional relationship between each locking piece protruding rearward from the locking device provided on the opening side and each locking piece of the outer frame is out of order, and the locking piece becomes the locking piece. There may be situations where the engagement is not successful. For this reason, when locking the inner frame, the open side of the inner frame must be lifted up a little and closed, which is troublesome. On the other hand, if it is raised too much, each locking piece can be engaged with each locking piece. There is a problem that the locking operation cannot be smoothly performed.

  Accordingly, the present invention has been made to solve the above-mentioned problems, and when locking the inner frame, it is not necessary to lift the open side of the inner frame each time, and the locking operation of the inner frame can be performed smoothly and accurately. The object is to provide a gaming machine.

  In order to achieve this object, a gaming machine according to the present invention is provided with an outer frame provided with a locking piece, an inner frame that is pivotally mounted on one side of the front surface of the outer frame, and an open side of the inner frame. And a locking device for locking or unlocking the inner frame to the outer frame via the locking piece, wherein the locking device is provided with an upward collar on the rear side. And a locking piece that is pivotally attached so that the collar portion is always urged upward and engages with the locking piece of the outer frame while rotating downward, and a predetermined height above the locking piece. And an upper horizontal plate portion that has a lower edge that slides into contact with an upper end edge of the locking piece and guides the locking piece to a normal position when the hook is engaged with the locking piece.

  Further, in the present invention, the lower horizontal plate portion that suppresses unnecessary rotating operation of the lock piece so as to prevent the engagement between the hook portion of the lock piece and the locking piece from being improperly released is provided with the lock. It is preferable to arrange so as to overlap the side of the piece.

  In the gaming machine according to the present invention, when the inner frame is pressed against the outer frame side and locked, the lower edge of the upper horizontal plate portion is in sliding contact with the upper end edge of the locking piece and guides the locking piece to the normal position. . As a result, the hook part can be easily engaged with the locking piece simply by pressing the inner frame to the outer frame side without lifting, and there is an effect that the locking operation can be performed smoothly and accurately. In addition, since the open side of the inner frame is not lifted, an unreasonable load, in particular, an upward load, is not applied to the shaft mounting portion, so that the shaft mounting portion is not easily damaged.

  In addition, the lower horizontal plate portion that suppresses unnecessary rotation of the lock piece is arranged so as to overlap the side of the lock piece so that the engagement between the lock piece's flange and the locking piece is not released by unauthorized means. For example, even if it tries to release the engagement with the locking piece by pushing down the collar part of the lock piece by the unauthorized tool, the unauthorized tool cannot be pushed down further by supporting the upper edge of the lower horizontal plate partway. Therefore, there is almost no possibility that the engagement of the buttock is released. This has the effect of preventing fraudulent acts performed by opening the inner frame.

These guide holes 62 and 62 are positioned so as to coincide with the guide holes 52 and 52 provided at the upper and lower portions of the first locking rod 51, but the longitudinal dimension is set longer than the guide holes 52 and 52. . The upper and lower movable members 58 and 59 are slid in the vertical direction by inserting the same guide pins 53 and 53 inserted into the guide holes 52 and 52 of the first locking rod 51 into the guide holes 62 and 62, respectively. It has come to be able to do. The upper and lower movable members 58 and 59 are provided with engaging recesses 63 that engage with the action pins 49 of the upper and lower lock pieces 44 and 44 to push up the action pins 49, respectively.

  The upper movable member 58 is provided with an engagement hole 64 which is located slightly above the center position and engages with the engagement piece 56 of the first locking rod 51, and below the upper and lower movable members 58 and 59. The first locking rod 51 is slid downward along with the sliding operation.

  The lower movable member 59 is provided with a locking recess 65 and a locking hole 66 located at the center thereof. The locking recess 65 is provided at the front end edge of the lower movable member 59, and the locking hole 66 is located at a predetermined position behind and below the locking recess 65. When the cam piece 39 is rotated in any one direction, the pressing piece portion 39a of the cam piece 39 is engaged with the locking recess 65, and the pushing piece portion of the cam piece 39 is engaged with the locking hole 66. 39b is engaged.

  A second locking rod 67 for locking or unlocking the front plate 17 is disposed on the inner surface of the inner wall 35b of the vertical main rod 35. The second locking rod 67 includes a vertically long plate-like locking rod main body 67a and a switching plate 67b positioned above the locking rod main body 67a. The switching plate 67b has a lower end in front of the upper end of the locking rod main body 67b. It is pivotally attached by a pin 68 so that it can tilt back and forth within a vertical plane.

  Vertical guide holes 69, 69 are formed in the upper and lower portions of the lock rod main body 67a, and guide pins 70, 70 fixed to the inner surface of the inner wall 35b of the vertical main rod 35 are inserted. Further, the narrowed upward collar portion 72 that protrudes forward from the upper and lower portions of the front edge of the locking rod main body 67a and can be engaged with the locking pieces 71 and 71 provided on the back surface of the front plate 17 with a predetermined interval therebetween. , 72 are provided. Each flange 72 protrudes forward of the inner frame 2 through a through hole formed in the inner frame 2. A protrusion 73 is provided at the lower end of the lock rod main body 67a, and the lock rod main body 67a, i.e., the first, is held by a tension spring 50 hooked between the protrusion 73 and the lock piece 48 of the lower lock piece 44. The two locking rods 67 are always urged upward.

  The switching plate 67b is moved upward by a tension spring 50 that is hooked between a projecting piece 74 provided substantially at the center of the rear end edge and a hooking piece 75 provided on the back surface of the front side wall 35a of the vertical main rod 35. And is also urged forward. A recess 76 is provided at the front edge of the switching plate 67b, and an engagement step 77 is provided at a substantially intermediate position of the rear edge. A through-hole 78 is opened behind the recessed portion 76 and slightly below.

  Then, the pressing piece 39a of the cam piece 39 can intervene in the recess 76 of the switching plate 67b through the locking recess 65 and the upper through hole 79a provided in the inner wall 35b of the vertical main rod 35, respectively. It is like that. Further, the push-up piece 39b of the cam piece 39 can intervene in the through-hole 78 of the switching plate 67b through the locking hole 66 and the lower through-hole 79b provided in the inner wall 35b of the vertical main rod 35, respectively. It is like that. A pressing piece 80 that protrudes forward by a predetermined length is provided at the upper end edge on the front side of the switching plate 67b.

  Therefore, when the transparent plate holding frame 13 is closed and locked, the front end of the pressing piece 80 abuts on the back side of the transparent plate holding frame 13 and the switching plate 67b is tilted backward and stopped. In this state, when the cam piece 39 is rotated in one direction and the pressing piece portion 39a is rotated downward, the pressing piece portion 39a engages with the locking recess 65, and the upper and lower movable members 58 and 59 are in the upper and lower portions. The first locking rod 51 slides downward as well as sliding downward against the tensile force of the tension springs 50, 50. Then, the upper and lower collar pieces 55, 55 move downward to disengage from the locking pieces 81, 81 provided on the back surface of the transparent plate holding frame 13, and unlock the transparent plate holding frame 13. . At this time, the second locking rod 67 is stopped without sliding downward by the pressing piece 39a of the cam piece 39a. Therefore, both the collar portions 72, 72 remain engaged with the locking pieces 71, 71 provided on the back surface of the front plate 17 from below, and the front plate 17 is not unlocked.

  On the other hand, when the transparent plate holding frame 13 is unlocked, the switching plate 67 b of the second locking rod 67 loses its support and tilts forward due to the urging of the tension spring 50. As a result, the positions of the pressing piece 39a and the engaging stepped portion 77 in the recess 76 are matched. Therefore, when the cam piece 39 that has been rotated once is returned to the initial position and is rotated again in the same direction, the pressing piece portion 39a is engaged with the engagement step portion 77 and the first locking rod 51 and the The two locking rods 67 are slid downward. As a result, the engagement between the collar portion 72 of the locking rod main body 67a and the locking piece 71 on the back surface of the front plate 17 is released, and the front plate 17 is unlocked. The transparent plate holding frame 13 and the front plate 17 are pressed from the front plate 17 first to the inner frame 2 side, so that the flange portions 55 and 72 of the first and second locking rods 51 and 67 are transparent plate holding frame. 13 is engaged with the locking pieces 71 and 81 of the front plate 17 for locking.

  When the cam piece 39 is rotated in the other direction, the lower movable member 59 in a state where the push-up piece portion 39b intervenes in the lower hole 79b of the inner side wall 35b in the vertical main rod 35 and the through hole 78 of the switching plate 67b. The upper and lower movable members 58 and 59 are slid upward by engaging with the locking holes 66. The upper and lower engaging recesses 63, 63 push up the action pins 49 at the front end against the urging force of the tension spring 50, and lower the flange 47 at the rear end of each lock piece 44. Thereby, engagement with each locking piece 41 of the outer frame 1 is released, and the inner frame 2 is unlocked. Further, only by pressing the inner frame 2 toward the outer frame 1 side, the locking pieces 41 of the outer frame 1 intervene between the upper horizontal plate portion 40a and the lower horizontal plate portion 40b, and the lock pieces 44 The portion 55 engages with each locking piece 41 from below, and the inner frame 2 is locked.

  The pachinko gaming machine P according to the present invention has the above-described configuration, and the operation thereof will be described with reference to FIGS. In the game state, as shown in FIGS. 9 (A), 9 (B), and 10, the hook portions 47 of the lock pieces 44 are engaged with the lock pieces 41 of the outer frame 1 from the lower side so that the inner frame 2 The transparent plate holding frame 13 is locked by being locked, and the flange portions 55 of the first locking rod 51 are engaged with the locking pieces 81 on the back surface of the transparent plate holding frame 13 from below. In addition, the front plate 17 is locked by engaging the hooks 72 of the lock rod main body 67a of the second lock rod 67 with the locking pieces 71 on the back surface of the front plate 17 from below. However, since the bent portion 82 to the rear of the lower edge of the transparent plate holding frame 13 is interposed in the lateral groove 83 on the upper edge of the front plate 17, the front plate 17 cannot be opened unless the transparent plate holding frame 13 is opened. It is supposed to be. Further, the switching plate 67b in the second locking rod 67 is inclined rearward, and the pressing piece portion 39a of the cam piece 39 and the engaging stepped portion 77 are in a positional relationship that does not match.

  Therefore, for example, when a trouble occurs on the game board 4 during the game, the employee in the hall inserts the key 34 into the lock hole 32a of the cylinder lock 32 from the front side, as shown by the arrow in FIG. It rotates in one direction (for example, inward direction). As a result, the pressing piece 39a of the cam piece 39 engages with the locking recess 65 of the lower movable member 59, and the first locking rod 51 slides downward together with the upper and lower movable members 58, 59, so 55 and 55 and the locking pieces 81 and 81 are disengaged. In this state, the transparent plate holding frame 13 is unlocked as shown by the arrow in FIG. 11 (b), and the trouble is solved.

  Furthermore, when trouble occurs in the rear side of the front plate 17, for example, the hitting ball launching portion 19a, the front plate 17 is unlocked while the transparent plate holding frame 13 is unlocked. At this time, the switching plate 67b However, the pressing piece 39a of the cam piece 39 and the engaging step 77 in the recess 76 are in a positional relationship in which the cam piece 39 is inclined forward by the urging of the tension spring 50. Therefore, the key 34 is returned to the initial position and rotated again in the same direction (inward direction) as shown by the arrow in FIG. As a result, the pressing piece 39a is engaged with the engaging step 77, and the second locking rod 67 is also slid downward together with the first locking rod 51. The engagement with the locking piece 71 is released. In this state, the front plate 17 is unlocked as shown by the arrow in FIG. In any case, when the trouble is solved, the transparent plate holding frame 13 and the front plate 17 are pressed against the inner frame 2 side, so that the flange portions 55 and 72 engage with the locking pieces 71 and 81, respectively, to hold the transparent plate. The frame 13 and the front plate 17 are locked.

  When trouble occurs on the back side of the inner frame 2, for example, the mechanism plate 23, the key 34 is rotated in the other direction (for example, the outer direction) as shown by the arrow in FIG. As a result, the push-up piece 39b of the cam piece 39 engages with the locking hole 66 of the lower movable member 59, and the upper and lower movable members 58, 59 are slid upward to push up the front end of each lock piece 44. . As a result, the engagement between the flange 47 at the rear end of each lock piece 44 and each lock piece 41 of the outer frame 1 is released, and the inner frame 2 is unlocked as shown by the arrow in FIG. Is resolved. When the trouble is solved, the inner frame 2 is pressed against the outer frame 1 side, whereby each flange 47 engages with each locking piece 41 and the inner frame 2 is locked.

  In the present invention, the distance gradually increases between the lower end of the upper horizontal plate portion 40a and the upper upper edge of the lower horizontal plate portion 40b as it advances backward so that the locking piece 41 can easily intervene therebetween. A taper 42 is provided. Therefore, when the inner frame 2 is closed, as shown in FIG. 14, each locking piece 41 on the outer frame 1 side is slidably brought into sliding contact with the taper 42 on the lower edge on the front end side of each upper horizontal plate portion 40a. Intervene between the lower horizontal plate portions 40a, 40b.

  That is, the lower edge of each upper horizontal plate portion 40a is in sliding contact with the upper edge of each locking piece 41, and guides the locking piece 41 to the normal position. As a result, the flange 47 of each lock piece 44 can be easily engaged with each lock piece 41 of the outer frame 1 simply by pressing it against the outer frame 1 side without lifting the inner frame 2, and its locking operation Can be performed smoothly and accurately. In addition, since the open side of the inner frame 2 is not lifted, an excessive load, particularly an upward load, is not applied to the shaft mounting portion 3, so that the shaft mounting portion 3 is not easily damaged.

  In addition, in a general hole, a fraudulent tool H such as a wire is inserted into the back side from the gap between the pachinko gaming machines P arranged side by side as shown in FIG. 15 and the pachinko gaming machine P adjacent thereto, There is a case where the upper and lower lock pieces 44, 44 are rotated to intentionally unlock the inner frame 2 to perform an illegal act.

  Therefore, in the present invention, the lower horizontal plate portion 40b is arranged below each upper horizontal plate portion 40a so as to overlap the side of each lock piece 44. Unnecessary rotation of each lock piece 44 is suppressed so that the engagement of the frame 1 with each lock piece 41 is not released. For this reason, the shape and size are appropriately set to perform the function. In the present invention, each lower horizontal plate portion 40b almost overlaps with each lock piece 44, and the upper portion of the flange portion 47 of each lock piece 44 protrudes slightly upward from the rear upper edge of each lower horizontal plate portion 40b. It is a degree. Therefore, even if it tries to release the engagement with each locking piece 41 by pushing down the collar portion 47 of each lock piece 44 by the unauthorized tool H, the unauthorized tool H is supported on the upper edge of the lower horizontal plate portion 40b in the middle of the operation, Since it becomes impossible to push down the collar part 47 any more, there is almost no possibility that engagement of the collar part 47 will be released. Thereby, prevention of the fraudulent act performed by opening the inner frame 2 is achieved.

  In the present invention, the front plate 17 is described as having only the upper ball tray 20 mounted thereon. However, the front plate 17 is mounted with the upper ball tray 20 together with the lower ball tray 21 without being limited thereto. Of course, the present invention can be applied.

  In addition, the pachinko gaming machine P according to the present invention engages the locking device 31 with the cam piece 39 of the cylinder lock 32 and slides in the vertical direction by the rotational movement of the cam piece 39 so that the transparent plate holding frame 13 is engaged. On the condition that the transparent plate holding frame 13 is unlocked, and the first locking rod 51 that can be unlocked is slid in the vertical direction by the rotation of the cam piece 39. Since the second locking rod 67 that can unlock the plate 17 is provided, even the member that unlocks the front plate 17 can be integrated and integrated into the locking device 31, and the mounting work can be simplified.

  Further, the front plate 17 can be unlocked in the same manner as the transparent plate holding frame 13 and the like by rotating the key 34 inserted into the cylinder lock 32 in any one direction. It is excellent in operability and safety without putting your hand injured. Further, the present invention is configured such that the inner plate 2 and the transparent plate holding frame 13 as well as the front plate 17 are unlocked by the key 34 inserted into the cylinder lock 32 of the locking device 31, so that the player can be viewed from the front as in the prior art. If the front plate 17 is opened by putting a hand into the back side of the front plate 17, it is impossible to do so, and there is an effect that an illegal act at that portion is prevented.
