Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine. [0002] A pachinko machine has a game board in which obstacle nails and various winning holes are arranged. The game board, like most other members, is supported by a middle frame. It constitutes a frame. A conventional main body frame is pivotally attached to one side edge so as to be openable and closable with respect to a peripheral outer frame. The body frame is
Only when the upper pivot part is deeply inserted by pushing up along the vertical direction, the lower pivot part moves in the vertical direction and can be detached and attached. further,
The main body frame includes a front frame that covers the game board on the front side so as to be freely opened and closed. The window frame is conventionally connected by a plurality of hinges. Each hinge is screwed to both sides by several screws. When attaching and detaching the main body frame at the time of manufacture or maintenance, the main body frame on which most of the members are mounted is heavy and must be carefully handled. Since the pivot shaft and the shaft hole are small and both the upper and lower pivot attachment portions must be moved in the vertical direction, it takes time and effort. In addition, when attaching and detaching the window frame, it is troublesome to remove a number of screws screwed to the hinge. Furthermore, since the window frame is screwed to the main body frame via a hinge, it is difficult to design the front surface of the main body frame, but if you try to attach the window frame so that it can be opened and closed without using a hinge, It is necessary to devise. Accordingly, the object of the present invention is to improve the operability of attaching and detaching the main frame or window frame of the pachinko machine, and to pivot the window frame in the same manner as the main frame.
The strength is sufficient with a simple configuration . In the present invention, a main body frame on which a game board is supported is removably pivoted on the upper and lower sides of one edge of the outer frame, and the front of the game board is provided. Is a pachinko machine that removably pivots a window frame supported by a transparent plate on the upper and lower sides of one side edge of the main body frame, and lifts the upper pivot of the pivot portion of the main body frame. It is possible to move up and down so that it returns to the protruding state, and in addition, the pivot on the upper part of the main body frame and the window frame is shared, and the window frame is pivotally attached to the lower part of the upper pivot. And DETAILED DESCRIPTION OF THE INVENTION Hereinafter, according to embodiments of the present invention,
This will be described with reference to the drawings. FIG. 1 is a perspective explanatory view of a front portion of a pachinko machine according to the present invention, and FIGS. 2 and 3 are partially exploded explanatory views of FIG.

The middle frame 7 that supports various members (only the window frame 8 to be described later) such as a game board on which obstacle nails and winning devices are arranged is used as a main body frame 32 in front of the outer frame 2. It is arranged in the part and inside and is pivotally attached. An upper mounting bracket 20 that constitutes a pivoting portion on the upper side of the main body frame 32 is fixed to the upper part of the left side edge of the middle frame 7, and a lower shaft hole 31 is provided on the lower side of the left side edge. A lower mounting bracket 30 that constitutes the lower pivoting portion projects forward. The upper mounting bracket 20 also shown in FIGS.
Consists of a semi-cylindrical part 21 and a fixing piece 22 to the middle frame 7 that extends to the lower rear side and to the right of the semi-cylindrical part 21. It is provided so as to penetrate through and extend downward. The upper surface of the upper shaft 23 is formed so as to descend to the left when the middle frame 7 is closed. Further, the upper axis 23
Is integrated with a T-shaped guide 24. further,
A spring 25 surrounding the upper shaft 23 is interposed between the guide 24 and the base 26 of the semicylindrical portion 21.
The spring 25 urges and supports the guide 24 upward so that the upper surface of the upper shaft 23 protrudes from the upper cover 27. The guide 24 is provided on the step 2 of the upper cover 27.
7a is passed through and is partially exposed on the rear side below the shaft peripheral portion 27b. The exposed portion of the guide 24 is provided so as to penetrate the lower portion 27c of the upper cover 27 and the base 26 so as to be movable up and down. Furthermore, the U-shaped side cover 2
8, the upper cover 27, and the base 26 are screws 29, 2
9 is screwed. The middle frame 7 is composed of the upper shaft 2 of the upper mounting bracket 20.
3 projecting into the upper shaft hole 4 of the coupling portion of the upper coupling fitting 3, and the lower shaft hole 31 of the lower mounting bracket 30 entering the pivot 10 of the lower coupling fitting 9 of the outer frame 2, It is pivotally attached to the outer frame 2 so that it can be opened and closed. Middle frame 7
In the closed state, the guide 24 of the upper mounting bracket 20
The lowering prevention piece 19 of the upper coupling fitting 3 comes into contact with the lower side (FIG. 6A). On the other hand, a middle connecting bracket 35 having a central shaft 36 is fixed substantially at the front center of the left edge of the middle frame 7. Between the upper mounting bracket 20 and the middle coupling bracket 35, the window frame 8 supporting the transparent plates 11, 11 covering the game board.
Is pivotally attached. The window frame 8 is a synthetic resin frame having a substantially circular opening and having a substantially square outer shape.
It is formed with the same width. A cut portion 13 is formed on the upper left side edge of the window frame 8. The front surface of the window frame 8 below the cut portion 13 is an upper bulging portion 15 having an inverted semiconical shape. Furthermore, the shaft hole 14 which comprises the upper side pivoting part of the window frame 8 is formed in the upper surface of the cutting part 13 bulge part. In addition, a rectangular locking hole 1 is formed at the rear of the upper surface of the cut portion 13.
8 is provided. On the other hand, a semi-conical lower bulging portion 16 is formed below the left edge of the window frame 8.
On the rear side, a middle shaft hole portion 17 including a middle shaft hole which is a part of the lower pivot portion of the window frame 8 is provided. The upper surface of the cut portion 13 of the window frame 8 is opposed to the lower surface of the base 26 of the upper mounting bracket 20 with a slight distance, and the lower end edge of the upper shaft 23 enters the shaft hole 14 of the cut portion 13, Further, a spacer 40 is interposed between the upper surface of the cut portion 13 and the lower surface of the upper mounting bracket 20, while the middle coupling bracket 35.
The central shaft 36 enters the central shaft hole portion 17 of the window frame 8 from above so that the window frame 8 is pivotally attached to the middle frame 7. The spacer 40 is a U-shaped member, and a claw member 41 that passes through a portion where the upper shaft 23 is not inserted therebetween and closes the open portion is connected to the upper bulging portion 15. It is locked and attached to the locking hole 18. The spacer 40 is formed with a semi-cylindrical surface so as to be continuous with the upper bulging portion 15, the upper mounting bracket 20, the coupling portion of the upper coupling bracket 3, and the like at the time of mounting. The window frame 8 and the middle frame 7 are fixed in a closed state by a common locking mechanism 43. Further, the depth of the cut portion 13 is set so that the spacer 40
And the total thickness of the upper mounting bracket 20 is approximately the same. In such a pachinko machine 1, the main body frame 32 is provided.
The middle frame 7 which is the support structure of can be attached as follows. First, the middle frame 7 is supported with the right side facing forward, and the lower portion of the left side edge is brought close to the left side edge of the outer frame 2 so that the lower shaft hole 31 of the lower mounting bracket 30 is connected to the lower pivot 1 of the lower connecting bracket 9.
Insert into 0 and engage. Next, with the lower shaft 10 entering the lower shaft hole 31 as a fulcrum, the upper left edge of the middle frame 7 is moved to the outer frame 2.
Move it closer to the left edge of. Then, as shown in FIG. 6 (b), the upper mounting bracket 20 is substantially horizontal to the connecting portion of the upper connecting bracket 3 with the upper surface of the upper shaft 23, which is lowered to the left in the closed state, lowered rearward. To approach. If the movement is continued as it is, the upper shaft 23 enters the guide portion 5, and is smoothly guided while being gradually pushed down by the guide portion 5 descending to the rear, and reaches the upper shaft hole 4. Upper shaft hole 4
When reaching the upper shaft 23, the upper shaft 23 is raised by the action of the spring 25 to return to the projecting state, and enters the upper shaft hole 4 to be pivotally attached. Here, since the upper shaft 23 is integrated with the guide 24 penetrating the base 26 and the like, the downward direction of the upper surface and the direction of vertical movement are determined, which can contribute to a stable mounting operation. When the upper shaft 23 and the upper shaft hole 4 are pivoted, the lower shaft hole 31 becomes horizontal and is completely pivoted with the lower shaft 10. When the pivoting is completed, the main body frame 32 can be closed and fixed by the lock mechanism 43. This pivot attachment is not particularly concerned with the vertical movement of the pivot axis 23,
This can be done with one touch only by moving the upper part with the lower left edge of the body frame 32 as a fulcrum. In the closed state, the upper surface of the upper shaft 23 is lowered to the left and does not follow the guide portion 5, and the lowering prevention piece 19 contacts the lower side of the guide 24. A situation where the upper shaft hole 4 is detached can be effectively prevented. The middle frame 7 can be removed from the outer frame 2 by releasing the lock mechanism 43 and opening at about 90 degrees, and inserting the guide 24 integrated with the upper shaft 23 into the guide portion 5 in a procedure. Although it is necessary, after pushing, it can be easily performed in a procedure almost opposite to that of pivot attachment. Furthermore, since the guide part 5 is provided in a fan shape, a width is given to the degree of opening of the middle frame 7 when the upper pivot part is engaged and disengaged,
The upper shaft 23 can be easily moved up and down in the opened state, and the detachability of the main body frame 32 can be improved. On the other hand, the window frame 8 can be removed in the next operation. That is, first, the lock mechanism 43 related to the window frame 8 is released, and the window frame 8 is opened about 90 degrees. Then, the claw member 41 of the spacer 40 appears on the right side.
Is pulled up and the spacer 40 is pulled out to the left. Since part of the upper shaft 23 is exposed by the extraction, the window frame 8 is slightly lifted so that the upper shaft 23 is inserted into the shaft hole 14 correspondingly. Then, since the central shaft hole portion 17 and the central shaft 36 are disengaged, if the lower portion of the window frame 8 is slightly moved forward and then pulled downward, the shaft hole 14 of the window frame 8 becomes the upper shaft 2 of the upper mounting bracket 20.
3 The upper pivot part of the window frame 8 is separated from the lower part, and the removal from the middle frame 7 is completed. The pivoting of the window frame 8 can be performed by the reverse operation of the removal. The pivotal attachment of the window frame 8 can remarkably improve the attachment / detachment operability, and the entire window frame 8 can be designed, for example, by providing the upper bulging portion 15 or the like. In addition, since the large pivot shaft 23 common to the main body frame 32 enters the shaft hole 14 with respect to the upper pivot portion, sufficient strength can be provided even when the window frame 8 is pivotally coupled to the middle frame 7. And the number of parts involved in pivoting can be reduced. It should be noted that the present invention is not limited to the above-described embodiment, and can be variously modified as shown in part below. Each pivoting portion only needs to have at least one pair of pivots and a shaft hole, and it does not matter in particular in which side the pivot is arranged. For example, the upper mounting bracket can be provided with an upper shaft hole without including the upper shaft, and the upper shaft hole capable of moving up and down can be provided in the main body frame. Further, the pivot shaft that moves up and down does not need to be provided only on the upper side, and can be provided only on the lower side or both. In the case where it is provided only on the lower side, the upper side is engaged first, so that it can be temporarily fixed in a suspended state, and the workability and mounting operability can be improved. Furthermore, the configuration for the vertical movement is not limited to that using a spring, and various configurations such as a configuration in which a thick rubber is attached and a configuration in which a repulsive force such as a magnet is used can be applied. In addition, the peripheral part of the upper shaft hole is urged and supported so that it can be moved up and down at the time of attachment / detachment, and the peripheral part can be returned and pivoted so that the shaft hole accepts the pivot. Both the pivot shaft and the upper shaft hole can be moved up and down. These changes can be applied at various pivot points. In addition, the guide portion does not need to be provided, it is not necessary to have a fan shape, and it may be rectangular. The upper surface of the upper axis may not be inclined. Furthermore, the location where the pivot is shared is not limited to the upper side, and may be the lower side. Furthermore, the window frame does not need to be provided with a cut portion, and the opening is not limited to a circle. In addition, each projecting shaft and each shaft hole may be provided on the right edge instead of the left edge. Further, the upper connecting bracket and the upper mounting bracket can be fixed by screwing, locking with protruding claws, riveting, or the like. Furthermore, the shape of the front part of the upper mounting bracket, spacer or bulge is not limited to a semicircular shape,
It can be flush with the window frame front. Furthermore, each member can be formed of various materials such as synthetic resin, metal, wood, and glass. In addition, pivoting using a pivot shaft or a shaft hole peripheral part that moves up and down removably is not only used for pivoting the main body frame to the outer frame, but also pivoting the window frame to the middle frame. Of course, the present invention can be applied to the pivotally attached portion of other pachinko machines, and can also be applied to a rotatable engaging portion of a gaming machine other than the pachinko machine. Similarly, the common use of the pivot can be applied to various pivot parts of the gaming machine. The present invention allows the upper pivot of the pivoting portion of the main body frame to be moved up and down so as to rise and return to the protruding state , and further the main body frame and window frame on the upper side. In the pivot joint with the common pivot, the lower part of the upper pivot
In addition, since the window frame is pivotally attached, the main frame or the window frame can be attached / detached by moving one of them substantially horizontally with the other engagement as a fulcrum. It can be done reliably with a single touch, with excellent operational feeling, improved manufacturing and maintenance efficiency, sufficient strength for pivoting the window frame, and simple As a configuration, there is an effect that the number of parts can be reduced.
