[Means for Solving the Problems]
In order to achieve the above object, the opening / closing member pivot structure of the pachinko machine according to the present invention includes an opening / closing member that needs to be opened / closed and rotated after mounting at a predetermined position of the pachinko machine. In one that is pivotally supported so as to be able to open and close by fitting with a shaft hole, one of the hinge receiving members is moved between a fitting position at which the hinge shaft is fitted and a non-fitting position at which the fitting is released. And a spring for urging the hinge receiving member to the fitting position is provided, and the pivot angle of the vertically displacing hinge receiving member in the urging direction is set. A stopper portion for regulating is provided (claim 1).
[0006]
In this case, an inclined surface portion inclined toward the non-fitting position may be provided at the tip end of the hinge receiving member that is displaced up and down (claim 2).
Further, a guide groove for guiding the hinge shaft into the shaft hole may be formed in the inclined surface portion (claim 3) .
[0007]
[Action]
According to the configuration of the first aspect of the present invention, one of the hinge receiving members is vertically displaced between the fitting position where the hinge shaft is fitted and the non-fitting position where the fitting is released. It is possible. Therefore, when attaching the opening / closing member, first, the hinge shaft is fitted into the shaft hole of the hinge receiving member that does not move vertically, and then, while the hinge receiving member that moves vertically is rotated and displaced to the non-fitting position. The hinge shaft is fitted into the shaft hole of the hinge receiving member. This eliminates the need to simultaneously align and fit the two upper and lower hinge shafts with the two shaft holes, and perform the alignment and fitting of the upper and lower two hinge shafts and the shaft holes one by one in order. be able to. In addition, since the hinge receiving member that is displaced up and down is urged to the fitting position by the spring, the fitting state between the shaft hole of the hinge receiving member and the hinge shaft is stably held by the spring. In addition, when the opening and closing member is attached, the rotation angle of the hinge receiving member in the biasing direction can be restricted by the stopper.
[0008]
On the other hand, when removing the opening / closing member, if the hinge receiving member that is displaced up and down is rotated and displaced to the non-fitting position against the spring , the hinge shaft that has been fitted up to that time will become the hinge receiving member. From the shaft hole. In this state, after the side on which the hinge shaft of the opening / closing member is disengaged is tilted to a position where the hinge shaft does not contact the hinge receiving member, the hinge shaft on the other side of the opening / closing member is pulled out from the shaft hole. Complete. Therefore, when removing the opening / closing member, there is no need to simultaneously pull out the two upper and lower hinge shafts from the shaft holes, and the upper and lower two hinge shafts can be sequentially pulled out one by one.
[0009]
According to the second aspect of the present invention, the tip of the hinge receiving member that is displaced up and down is provided with the inclined surface that is inclined toward the non-fitting position side. If the hinge shaft is pushed into the shaft hole side by abutting against the inclined surface of the member, the hinge receiving member pushes up to the non-fitting position side against the spring as the tip of the hinge shaft slides the inclined surface toward the shaft hole (or). Down). For this reason, when attaching the opening / closing member, there is no need to perform an operation of gripping the hinge receiving member with a finger or the like and displacing the hinge receiving member to the non-fitting position.
[0010]
Furthermore, according to the third aspect, when the opening / closing member is attached, the hinge shaft is smoothly guided into the shaft hole by the guide groove provided on the inclined surface portion of the hinge receiving member, and the positioning and fitting of the hinge shaft are further facilitated. to become.

【Example】
Hereinafter, a first embodiment in which the present invention is applied to a pivot structure of a back component pack will be described with reference to FIGS. Metal hinge receiving members 22 and 23 are attached to upper and lower sides of the inner frame 21, respectively. A lower hinge receiving member (hereinafter, referred to as a “lower hinge receiving member”) 23 is fixed to a lower portion of the inner frame 21 by a screw (not shown) or the like, and a shaft hole 24 of the lower hinge receiving member 23 is formed. The position does not move.
[0012]
On the other hand, an upper hinge receiving member (hereinafter, referred to as an “upper hinge receiving member”) 22 has an axial pin attached to a mounting bracket 26 fixed to a top of an inner frame 21 with screws 25 as shown in FIGS. 27 so as to be rotatable in the vertical direction. At the base end of the upper hinge receiving member 22, a stopper portion 28 for restricting a downward rotation angle is formed by bending at a right angle downward, and the stopper portion 28 contacts the mounting bracket 26 and rotates. Is a fitting position where the shaft hole 29 formed in the upper hinge receiving member 22 is fitted to a hinge shaft 34 described later.
[0013]
An inclined surface portion 31 that is inclined obliquely upward is integrally formed at a tip portion of the upper hinge receiving member 22. Further, the shaft pin 27 which pivotally support the upper hinge receiving members 22, it Jiri coil spring 32 is mounted, multiplying the both ends of the torsion coil spring 32, respectively and mounting bracket 26 and the upper hinge receiving member 22 Thus, the upper hinge receiving member 22 is urged to rotate to the lower fitting position.
[0014]
On the other hand, although not shown, the back part pack 33, which is an opening / closing member, is a unit formed by assembling various back parts such as a prize ball tank, a ball rail, a prize ball discharge device, and a collecting gutter into a back pack door. . On both upper and lower sides of the back part pack 33, mounting brackets 36 and 37 to which hinge shafts 34 and 35 are fixed are mounted by screws 38 (see FIG. 3). In this case, the upper hinge shaft 34 is fixed upward and fitted into the shaft hole 29 of the upper hinge receiving member 22 from below, and the lower hinge shaft 35 is fixed downward and the shaft hole of the lower hinge receiving member 23 is fixed. 24 is fitted from above. Further, each of the hinge shafts 34 and 35 has a tapered tip portion in order to smoothly fit into each of the shaft holes 24.
[0015]
Next, a procedure for attaching the back part pack 33 to the inner frame 11 will be described. First, the lower hinge shaft 35 is fitted into the shaft hole 24 of the lower hinge receiving member 23 as shown by a two-dot chain line in FIG. Next, when the upper side of the back component pack 33 is rotated toward the inner frame 21 as shown by the arrow A in FIG. 1A with the shaft hole 24 of the lower hinge receiving member 23 as a fulcrum, the hinge shaft 34 is eventually formed. Of the upper hinge abuts against the inclined surface portion 31 of the upper hinge receiving member 22. In this state, when the upper side of the back component pack 33 is pushed into the inner frame 21 side, the hinge shaft 34 moves the upper hinge receiving member 22 as the upper end of the hinge shaft 34 slides the inclined surface portion 31 toward the shaft hole 29 side. It slides toward the shaft hole 29 while being pushed up against the torsion coil spring 32. As a result, when the tip of the hinge shaft 34 matches the shaft hole 29, the upper hinge receiving member 22 is pushed down to the lower fitting position by the spring force of the torsion coil spring 32, and the shaft hole 29 fits into the hinge shaft 34. It is held in the closed state, and the mounting operation of the back part pack 33 is completed.
[0016]
In this manner, by attaching the upper hinge receiving member 22 so as to be vertically movable, there is no need to align and fit the two upper and lower hinge shafts 34 and 35 into the two shaft holes 24 and 29 at the same time. The positioning and fitting of the hinge shafts 34, 35 and the shaft holes 24, 29 at the locations can be performed one by one in order, so that the mounting operation of the back part pack 33 can be performed smoothly, and work efficiency can be improved. Can be improved. Moreover, since the upper hinge receiving member 22 that rotates vertically is urged to the fitting position by the torsion coil spring 32, the fitting state between the shaft hole 29 of the upper hinge receiving member 22 and the hinge shaft 34 is changed by the torsion coil spring. It can be held by the spring force of 32, and the mounting state can be stabilized.
[0017]
Moreover, since the inclined surface portion 31 inclined toward the non-fitting position side is provided at the distal end portion of the upper hinge receiving member 22, as shown in FIG. If the tip of the hinge shaft 34 is pressed against the inclined surface portion 31 of the upper hinge receiving member 22 and pushed into the shaft hole 29 side, the upper hinge receiving member 22 is moved as the distal end of the hinge shaft 34 slides the inclined surface portion 31 toward the shaft hole 29 side. Is automatically pushed gradually toward the non-fitting position side (upper side) against the torsion coil spring 32. For this reason, at the time of attaching the back component pack 33, the work of pinching the upper hinge receiving member 22 with a finger or the like and displacing the upper hinge receiving member 22 to the non-fitting position becomes unnecessary, and the attaching workability is further improved.
[0018]
On the other hand, when removing the back component pack 33, the inclined surface portion 31 of the upper hinge receiving member 22 is picked up with a finger and lifted upward against the torsion coil spring 32. Thus, when the upper hinge receiving member 22 is rotated to the non-fitting position, the hinge shaft 34 that has been fitted so far comes out of the shaft hole 29 of the upper hinge receiving member 22. In this state, the upper part of the back part pack 33 is tilted to a position (a position indicated by a two-dot chain line in FIG. 1A) that does not contact the upper hinge receiving member 22, and then the lower hinge of the back part pack 33 is tilted. When the shaft 35 is pulled out from the shaft hole 24, the operation of removing the back part pack 33 is completed. Therefore, when removing the back part pack 33, there is no need to simultaneously extract the upper and lower hinge shafts 34 and 35 from the shaft holes 24 and 29, and the upper and lower hinge shafts 34 and 35 are sequentially extracted one by one. The removal of the back part pack 33 can be performed very easily.

Further, as in the second embodiment of the present invention shown in FIG. 4, a guide groove 41 for guiding the hinge shaft 34 into the shaft hole 29 may be formed in the inclined surface portion 31.
[0020]
According to the second embodiment, at the time of mounting the back part pack 33, the upper end of the hinge shaft 34 is abutted against the guide groove 41 of the inclined surface portion 31 of the upper hinge receiving member 22, and the back part pack 33 is moved toward the shaft hole 29. When pushed in, the hinge shaft 34 is smoothly guided into the shaft hole 29 by the guide groove 41, and the positioning and fitting of the hinge shaft 34 to the shaft hole 29 are further facilitated. In this case, it goes without saying that the guide groove 41 may be extended to the shaft hole 29.
