Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a ball and ball game machine in which a transparent plate holding frame is connected to a front surface of an inner frame mounted on an outer frame by a pair of upper and lower multiaxial hinges.
[0002]
[Prior art]
Conventionally, a pachinko game machine, which is a kind of ball-and-ball game machine, has an inner frame body that is freely openable and closable by an upper and lower hinge mechanism on one side of a vertically rectangular outer frame, and a front face of the inner frame body. A transparent plate holding frame that covers the front surface of the game board is pivotally mounted on one side thereof so that it can be opened and closed with only one axis.
[0003]
In recent years, pachinko gaming machines have elaborated design interests, such as molding the front surface with synthetic resin material and projecting to the front side in order to excite the interest of the game, so that the thickness of the transparent plate holding frame is very large. It tends to be larger. On the other hand, when the transparent plate holding frame of the pachinko gaming machine arranged in the gaming machine installation island is opened to one side, since the transparent plate holding frame is pivoted by only one axis, the other adjacent pachinko game is performed. This means that there is a risk of interfering with the transparent plate holding frame of the machine, the protrusion of the ball lending machine, etc., and hindering its opening and closing operation. It is conceivable to use a multi-axis hinge consisting of a shaft.
[0004]
[Problems to be solved by the invention]
By the way, since the multi-axis hinge has a degree of freedom, for example, even in a state where the transparent plate holding frame is closed on the front surface of the inner frame body and locked, if the supporting side of the transparent plate holding frame is pulled forward, the supporting side becomes Slightly emerge to the front. When the transparent plate holding frame protrudes to the front side in this way, an unnecessary gap is created between the inner frame body and the transparent plate holding frame, from which wire such as a piano wire crawls on the game board surface and the prize winning device is intentionally activated. There is a possibility that the wrongdoing of obtaining a prize ball may be performed.
[0005]
Therefore, the present invention has been made in view of the above problem, and in a state in which the transparent plate holding frame is closed on the front surface of the inner frame body and locked, the inner side of the transparent plate holding frame is prevented from floating forward. Provided is a ball-and-play machine in which a wire rod such as a piano wire is laid on a game board through a gap between a body and a transparent plate holding frame to prevent a fraudulent act of intentionally operating a prize winning device to obtain a prize ball. It is intended to do so.
[0006]
[Means for Solving the Problems]
In order to achieve such an object, the present invention provides a structure in which a transparent plate holding frame can be connected to a front surface of an inner frame body mounted on an outer frame by a pair of upper and lower multiaxial hinges, wherein each of the multiaxial hinges is A support member attached to the inner frame body side, a support member attached to the transparent plate holding frame side via an attachment member, and a link in which rod-shaped shaft portions provided at both ends are rotatably supported by the support members. A ball-and-ball game machine comprising: a plate, wherein the link member is located between the pivots at both ends of the link plate, and the link plate is closed when the transparent plate holding frame is closed and locked. And an outer plate that is pressed toward the inner frame body by the pressing force and is bent against its elastic force.
[0007]
In this manner, in a state where the transparent plate holding frame is closed and locked, the link plate is pushed by the outer plate of the mounting member toward the inner frame with a predetermined pressing force, and is bent against the elastic force thereof. Therefore, the pivot side of the transparent plate holding frame is pulled toward the inner frame body, and thereby, even if the same side of the transparent plate holding frame is raised to the front side, the force is prevented, and the inner frame body and the transparent plate holding frame are Unnecessary gaps are not opened between them, and this prevents fraudulent acts performed by causing a wire such as a piano wire to crawl on the game board surface from the gaps.

It can be done without any trouble.
[0014]
As shown in FIG. 9, a multi-axis hinge 31 for connecting the transparent plate holding frame 5 is provided on a front side of the inner frame body 4 as shown in FIG. The multi-axis hinge 31 is a double-barreled double-axis hinge having two link plates, is made of metal, and is disposed in a pair on the front surface of the inner frame body 4. As shown in FIGS. Support members 32a and 32b attached to the side and the transparent plate holding frame 5 side, respectively, and two link plates 33a and 33b connecting the support members 32a and 32b. The support member 32a attached to the inner frame body 4 is formed by bending the side plate 35 from both end edges of the bottom plate 34 at substantially right angles in the same direction. The dimension between the both side plates 35 is set to be substantially the same as the vertical width dimension of the link plates 33a, 33b, and the link plates 33a, 33b can rotate between them. Also, two pairs of shaft holes 36 are formed in the both side plates 35 so as to face each other, and among these, the shaft holes 36 of one side plate 35 are introduction grooves opened at the outer edge of the side plate 35. 36a. The bottom plate 34 is provided with two recesses 37 that are conically recessed in the same direction as the side plate 35, and a screw hole 38 is formed at a deep end thereof.
[0015]
On the other hand, the support member 32b attached to the transparent plate holding frame 5 side is also formed by bending the side plate 35 from both end edges of the bottom plate 34 at substantially right angles in the same direction, and the dimension between the both side plates 35 is the link plates 33a, 33b. Are set so that they are substantially the same as the vertical width dimension and the link plates 33a and 33b can rotate between them.

Reference numeral 40 denotes a metal connecting member for connecting the upper and lower first link plates 33a. The connecting plates 40b and 40c having different heights from the both end edges in the short direction of the vertically long substrate 40a are outwardly formed at substantially right angles. It is formed by bending. Then, the vertically long substrates 40a are abutted on one side surface of the upper and lower first link plates 33a such that the support plates 40b and 40c face outward, and are caulked and fixed to each other. Thus, when the transparent plate holding frame 5 is opened and closed, the upper and lower first link plates 33a perform a synchronous operation, and the operation shift between the upper and lower multi-axis hinges 31 is reduced, and the transparent plate holding frame 5 Wobble is suppressed. Reference numeral 41 denotes a metal attachment member for detachably attaching the transparent plate holding frame 5, and the outer plates 41b and 41c are bent at substantially right angles from both ends in the short direction of the vertically long contact plate 41a in the same direction. Molded. In the vertically long contact plate 41a, mounting ports 42 are opened at upper and lower portions, and a horizontal locking rod 43 is laid across the mounting ports 42. The dimension between the locking rods 43 is the same as the dimension between the upper and lower mounting members 45 provided on the transparent plate holding frame 5 side described later. Then, the vertically long contact plates 41a are brought into contact with the bottom plates 34 of the respective support members 32b so that the respective support members 32b are fitted between the outer plates 41b and 41c, and are caulked and fixed to each other.
[0018]
The transparent plate holding frame 5 is formed to have a size that covers the upper half portion of the inner frame body 4 over the entire width, and has a circular opening 44 formed at the center thereof so that the game part on the front of the game board 14 can be visually recognized. It is composed of a main body frame 5a made of synthetic resin and a reinforcing metal plate 5b mounted on the back side of the main body frame 5a. The main body frame 5a is designed such that the outer peripheral edge of the opening 44 projects most to the front side and looks like a volcano, and the light-transmitting portion and the non-light-transmitting portion are intricately complicated. In. A mounting member 45 for fitting to each of the locking rods 43 is vertically fixed to a shaft support side of the reinforcing metal plate 5b by screws 45a. As shown in FIG. 12, each mounting member 45 has a supporting portion 46 screwed to the reinforcing metal plate 5b, and is mounted on the supporting portion 46 so as to be slidable in the vertical direction, and an inclined surface 47 is provided at an upper end thereof. A U-shaped groove 50 is provided which comprises a slider 48 and a spring 49 for constantly urging the slider 48 upward. The support portion 46 is provided with a U-shaped groove 50 in which the locking rod 43 is held.
[0019]
Therefore, in order to attach the multi-axis hinge 31 to the front surface of the inner frame body 4, as shown in FIG. 13 (a), one of the support members 32a of the upper and lower multi-axis hinges 31 is connected to the bottom plate 34 by the inner frame. It is arranged on the front of the main frame 11 so as to face the front of the main frame 11 of the body 4. Then, in a state where the screw holes 38 on the support member 32a side and the through holes 51 formed in the main frame 11 are aligned with each other, as shown in FIG. A countersunk screw 52 as a screw is detachably screwed into the hole 38 through a through hole 51. At this time, the head 52a of the countersunk screw 52 fits into the recess 37, and a part of the head 52a does not protrude rearward from the rear surface of the main frame 11; 14 so as not to cause any trouble when it is attached. In this way, the support member 32a is attached to the inner frame 4 side. Conversely, by removing each of the countersunk screws 52 from the rear side of the main frame 11, each support member 32a is removed from the inner frame 4. Can be easily removed. Therefore, if the transparent plate holding frame 5 is inclined to the open side by its own weight and the multiaxial hinge 31 is bent or damaged due to this, the countersunk screw 52 is removed and the multiaxial hinge 31 is removed from the inner frame body 4. Remove the hinge 31. At this time, since the transparent plate holding frame 5 is detachably attached to the mounting member 41 as described below, the transparent plate holding frame 5 can also be separated from the multi-axis hinge 31. Therefore, as a result, only the multi-axis hinge 31 is used, and the multi-axis hinge 31 can be easily replaced with a new multi-axis hinge 31. In addition, since only this replacement is required, there is no waste and no extra cost is incurred. As long as the mounting of the game board 14 is not hindered, the mounting means of the multi-axis hinge 31 to the inner frame 4 may be other mounting means such as an engaging piece and an engaging hole. In addition, the multi-axis hinge can be applied to other types having a different configuration from the multi-axis hinge 31.
[0020]
On the other hand, in order to mount the transparent plate holding frame 5 to the mounting member 41, the mounting members 45 of the transparent plate holding frame 5 are attached to the upper and lower locking rods 43 of the mounting member 41 fixed to the other support members 32b. The transparent plate holding frame 5 is pressed against the mounting member 41 with the locking rod 43 brought into contact with the inclined surface 47 of the slider 48 through the mounting port 42. Thus, the slide bar 48 is retracted by the locking rod 43 against the bias of the spring 49. Further, by pressing the transparent plate holding frame 5, the locking rod 43 is disengaged from the tip of the inclined surface 47 and fits into the U-shaped groove 50 of the support part 46, and at the same time, the slide 48 is returned to the original state by the bias of the spring 49. After returning to the position, the locking rod 43 is held so as not to come off as shown in FIG. In this manner, the transparent plate holding frame 5 is rotatably and detachably attached to one side of the front surface of the inner frame body 4 by the multiaxial hinge 31. Since the locking rod 43 is disposed horizontally, the transparent plate holding frame 5 is easy to attach, and in the attached state, the transparent plate holding frame 5 is firmly fixed and very stable. When the transparent plate holding frame 5 is detached from the inner frame body 4, the locking rod 43 is pulled out from the U-shaped groove 50 and removed while the slider 48 is retracted with a finger against the bias of the spring 49. do it.
[0021]
When the opened transparent plate holding frame 5 is gently closed, the upper and lower multi-axis hinges 31 firstly move the front edge of the short support plate 40b of the connecting member 40 to the outer edge of the inner frame body 4 as shown by the solid line in FIG. Then, the leading edge of the outer plate 41b inside the mounting member 41 comes into contact with the outer surface of the second link plate 33b and stops once. At this time, the vertically long contact plate 41 a of the attachment member 41, that is, the transparent plate holding frame 5 is inclined at a predetermined angle in a direction in which the transparent plate holding frame 5 opens with respect to the front surface of the main frame portion 11 of the inner frame 4. In this case, the predetermined angle A is preferably, for example, about 3.5 degrees. From this state, when the transparent plate holding frame 5 is further pressed against the inner frame body 4 and closed as shown by the chain line in FIG. 15, the second link plate 33b is pressed with a predetermined pressing force by the outer plate 41b and the elasticity thereof is increased. Bends against In the state where the transparent plate holding frame 5 is closed and locked, this pressing force is applied between the inner frame 4 and the transparent plate holding frame 5 even if the pivot side of the transparent plate holding frame 5 is to be pulled out to the front side. It is set so that unnecessary gap S is not opened.
[0022]
As described above, one rod-shaped shaft portion 39 (39a) serving as a fixed end of the second link plate 33b is located inside the outer plate 41b, and the other rod-shaped shaft portion 39 (39b) serving as a free end is located outside the outside plate 41b. In the state where the transparent plate holding frame 5 is finally closed and locked, the second link plate 33b is pushed toward the inner frame body 4 with a predetermined pressing force by the outer plate 41b of the mounting member 41. And bends against the elastic force. As a result, the pivot side of the transparent plate holding frame 5 is pulled toward the inner frame body 4, so that even if the same side of the transparent plate holding frame 5 is to be raised to the front side, the force is prevented, and It becomes difficult to open an unnecessary gap S between the frame 4 and the transparent plate holding frame 5. Therefore, an illegal act performed by causing a wire such as a piano wire to crawl on the surface of the game board 14 from the gap S is prevented. The means for preventing this misconduct works with the overhanging plate portion 29 provided with the cutout recess 30b which engages with the ridge portion 30a on the upper surface of the transparent plate holding frame 5 as described above. There is a benefit when the plate portion 29 is destroyed.
[0023]
In addition, in the above state, a force that tries to protrude to the front side of each of the multiaxial hinges 31 is prevented, and at the same time, a force that tries to open the transparent plate holding frame 5 is opened. Therefore, when the transparent plate holding frame 5 is opened, the opening side of the transparent plate holding frame 5 naturally projects forward when unlocked, because a reaction force to open the transparent plate holding frame 5 is applied in advance. Easy to open.
[0024]
On the back surface of the reinforcing metal plate 5b of the transparent plate holding frame 5, a groove frame member 53 formed in a U-shape so as to surround the left and right sides and the lower side except for the upper side of the opening 44 of the main body frame 5a. It is provided integrally. In addition, a transparent frame 54, which is disposed in parallel with two glass plates 54a as transparent plates through which the game board 14 can be seen through the groove frame member 53, is integrally fitted and held from above. . At the front of the reinforcing metal plate 5b and between the main frame 5a and the main frame 5a, middle / treble speakers 55 and LEDs 56 that exhibit an electric decoration effect are disposed at appropriate positions. In the reinforcing metal plate 5b, a through hole 58 is formed in the open side of the reinforcing metal plate 5b, through which a cylinder lock 57 for locking the inner frame 4 and the transparent plate holding frame 5 faces. 5a is provided with a key insertion hole 59 in which the key hole 57a at the front end of the cylinder lock 57 faces.
[0025]
As shown in FIG. 16, a metal tamper-resistant frame 60 into which the front end of the cylinder lock 57 can be fitted is provided on the rear surface of the main frame 5a so as to correspond to the key insertion hole 59. The fraud prevention frame 60 is formed in a box frame shape with an open rear surface, and a flange 60a extending outward in a vertical plane is provided around the outer peripheral edge of the rear end. A screw insertion hole 60b is formed in the flange 60a. Is provided. Then, the screw 62 is screwed into a screw hole 61 provided on the rear surface of the main body frame 5a via the screw insertion hole 60b, whereby the fraud prevention frame 60 is attached. An insertion hole 60d communicating with the key insertion hole 59 is formed in the front side wall 60c of the fraud prevention frame 60. Then, as shown in FIG. 17, when the transparent plate holding frame 5 is closed, the keyhole portion 57a abuts on the front side wall 60c and coincides with the insertion hole 60d to firmly close the insertion hole 60d. The attachment position of the fraud prevention frame 60 and the inner diameter of the insertion hole 60d are set so that no gap is formed between the insertion hole 60d and the insertion hole 60d. Therefore, in a state where the transparent plate holding frame 5 is closed, the insertion hole 60d is always closed by the keyhole 57a, and the insertion hole 60d and the keyhole 57a are passed through the through hole 58 along the side surface of the cylinder lock 57. It is impossible to insert a thin wire such as a piano wire from between the above and the above, thereby preventing fraud.
[0026]
The interval between the upper and lower walls 60e of the fraud prevention frame 60 is set slightly wider than the height of the cylinder lock 57, and their inner surfaces are slightly inclined so as to gradually widen rearward. Further, the inner peripheral edge of the rear end opening is curved so that the cylinder lock 57 can enter smoothly without being supported. Therefore, as shown in FIG. 18, when the transparent plate holding frame 5 is closed, the cylinder lock 57 is fitted while slidingly contacting the fraud prevention frame 60, so that the cylinder lock 57 also serves as a guide. The keyhole 57a can be guided to the correct position with respect to the key insertion hole 59 only by pushing it into the fourth side, and the transparent plate holding frame 5 can be closed smoothly. Further, in a state where the transparent plate holding frame 5 is closed, the tip of the cylinder lock 57 is fitted in the fraud prevention frame 60, so that the stability of the transparent plate holding frame 5 is increased.
[0027]
As shown in FIG. 3, the locking mechanism 63 of the inner frame 4 is attached to the back side of the inner frame 4 and the open side thereof. Further, a fixing plate 64 is fixed to a side edge portion located on the front side of the inner frame body 4 and located on the open side, and a locking mechanism 65 of the transparent plate holding frame 5 is assembled inside the fixing plate 64. ing. A vertically long case body 66 containing a setting mechanism for using the cylinder lock 57 as a variable type is attached to the front surface of the fixing plate 64, and the cylinder lock 57 is fixed to the front surface. As a result, the cylinder lock 57 can be pulled out to the front side, and even when the main body frame 5a is formed so as to protrude, the keyhole portion 57a can be aligned with the key insertion hole 59. Latches 67 are attached to the upper and lower portions of the open inner surface of the outer frame 2, and L-shaped latches are provided on the open side surface of the groove frame member 53 provided on the back surface of the transparent plate holding frame 5. 68 are fixed. Then, when a key (not shown) is inserted into the key hole portion 57a of the cylinder lock 57 and rotated in one direction, the locking mechanism 63 of the inner frame body 4 is operated, and the locking fittings 67 of the outer frame 2 and Is disengaged, and the inner frame body 4 can be opened. On the other hand, when the inner frame 4 is pressed against the outer frame 2 in a state where the inner frame 4 is opened, the locking mechanism 63 of the inner frame 4 automatically operates to lock the upper and lower portions of the outer frame 2. The inner frame 4 is locked to the outer frame 2 by being engaged with the metal fitting 67.

The present invention provides a method for mounting the link plate 33b to the inner frame with a predetermined pressing force when the transparent plate holding frame 5 is closed and locked on the mounting member 41 between the shaft support portions at both ends of the link plate 33b. Since the outer plate 41b which pushes toward the body 4 and bends against its elastic force is provided, in a state where the transparent plate holding frame 5 is closed and locked, the supporting side of the transparent plate holding frame 5 is always the inner frame body. It is pulled to the 4 side. Therefore, even if the transparent plate holding frame 5 is intentionally pulled out to the front side, an unnecessary gap is not opened between the inner frame 4 and the transparent plate holding frame 5, thereby preventing fraud.
