Description

  The present invention relates to a ball game machine such as a pachinko gaming machine having various board surface mounting parts on the board surface of the game board.

  In general, a ball game machine such as a pachinko machine is provided with board surface mounting parts such as a center character, a prize opening, a big prize opening, a start opening, and a windmill on the board surface of the game board. A fixing method using a screw is generally used as a method for fixing a board surface mounting component to a game board, but a fixing method using a mounting claw has also been proposed in order to facilitate mounting work and reduce costs. (For example, refer to Patent Document 1).

  The mounting claw is formed integrally with or separately from the panel surface mounting component, and the material and dimensions are set so that appropriate elastic deformation is allowed. Usually, the mounting claws are formed so as to project back-to-back as a set of two, and the tip end portion is provided with a tapered portion that performs a press-fitting guide and an engaging claw portion that projects outward.

When mounting the panel surface mounting component with the mounting claw, the mounting claw protruding from the panel surface mounting component is inserted into the mounting hole of the game board in a press-fit manner. At this time, the pair of mounting claws are elastically deformed in directions close to each other by a guide of a tapered portion formed at the tip portion. When the attachment claws are inserted until the entire engagement claws protrude from the back surface of the game board, the set of attachment claws spread outward by elastic restoring force. Thereby, the engaging claw part engages with the back side of the game board, and the board surface mounting component is fixed to the game board.

  However, the board surface mounting parts fixed to the game board with the mounting claws are not easy to remove, and there is a problem that the removal work is troublesome when recycling the ball game machine. This is because, when removing the panel mounting parts, it is required to simultaneously perform the work of inclining a set of mounting claws inward and the operation of pushing the mounting claws to the front side, especially for one panel mounting member. When there are a plurality of nail fixing points, the workability during removal becomes remarkable.

The present invention was created for the purpose of solving these problems in view of the above circumstances, and inserts a mounting claw that integrally protrudes from the back surface of the board surface mounting component into the mounting hole of the game board, In the ball game machine for fixing the board surface mounting component to the game board by engagement of the mounting claws with the back side of the game board, the mounting claws are formed to protrude in a back-to-back manner as a pair, Between the protruding middle parts of a set of mounting claws , it is possible to engage with a removal jig inserted into the mounting hole from the back side of the game board, and the mounting claws are fixed by the pressing force received from the removal jig. Detachment engaging part that is deformed in the release direction is provided in a spanning manner, and the board surface mounting part can be removed from the game board without directly contacting the removal jig to the back of the part This is a bullet ball game machine characterized by that. Thereby, removal of a board surface attachment component can be made easy and the recyclability of a ball game machine can be improved. Also, if multiple removal jigs are used, multiple mounting claws can be removed at the same time, so even if there are multiple fixing points for one panel mounting part, it can be easily removed. A plurality of panel surface mounting parts can be removed at the same time. Further, not only can the engagement with the removal jig be improved, but also the set of attachment claws can be reliably tilted inward by the pressing force of the removal jig to release the fixation of the attachment claws.

  According to the present invention as described above, while the board surface mounting component is fixed to the game board with the mounting claws, the mounting claws are engaged with the removal jig inserted into the mounting hole from the back side of the game board. A removal engagement part that can be deformed in the unlocking direction by the force received from the removal jig is formed, so the removal jig is inserted into the attachment hole from the back side of the game board. Thus, it is possible to simultaneously perform the disengagement operation and the push-out operation of the attachment claw simply by pressing the removal engagement portion of the attachment claw. Thereby, removal of a board surface attachment component can be made easy and the recyclability of a ball game machine can be improved. Also, if multiple removal jigs are used, multiple mounting claws can be removed at the same time, so even if there are multiple fixing points for one panel mounting part, it can be easily removed. A plurality of panel surface mounting parts can be removed at the same time.

  Next, embodiments of the present invention will be described with reference to the drawings. 1 and 2, reference numeral 1 denotes a pachinko gaming machine (bullet ball gaming machine).

As shown in FIG. 3, the game board 4 has a board surface such as a game nail 14, a launch rail 15, a center accessory 16, a big prize opening 17, a prize opening 18, a start opening 19, an out opening 20, and a windmill 21. are configured with a fitting 23, of these board mounting parts 23, board mounting parts 23, except for gaming nail 14 with the firing rail 15 can be attached by engaging hooks 22 on the game board 4. Hereinafter, an embodiment of the mounting claw 22 which is a feature of the present invention will be described.

The mounting claw 22 is integrally formed with the panel surface mounting component 23 as shown in FIG. As shown in FIG. 4 (B), what is formed separately from the panel mounting component 23 is a reference example . Further, plastic is usually selected as the material of the mounting claw 22, but any material can be used as long as appropriate elastic deformation is allowed. Usually, the mounting claws 22 are formed so as to protrude back-to-back as a set of two, and at the front end portion, there are a tapered portion 22a that performs a press-fitting guide and an engaging claw portion 22b that protrudes outward. Yes.

When mounting the board surface mounting component 23 with the mounting claw 22, the mounting claw 22 protruding from the board surface mounting component 23 is inserted into the mounting hole 4a of the game board 4 in a press-fit manner. At this time, the pair of mounting claws 22 are elastically deformed in directions close to each other by the guide of the tapered portion 22a formed at the tip portion. When the attachment claws 22 are inserted until the entire engagement claws 22b protrude from the back surface of the game board, the set of attachment claws 22 spreads outward by an elastic restoring force. Thereby, the engaging claw portion 22b is engaged with the back side of the game board 4, and the board surface mounting component 23 is fixed to the game board 4.

As shown in FIG. 4C, the mounting claw 22 can be integrally formed on the panel surface mounting component 23 via a thin portion 23a that can be elastically deformed in the mounting hole insertion direction. Such a thin-walled portion 23 a can be secured, for example, by forming a recess of about 0.2 to 0.3 mm in the protruding base portion of the mounting claw 22. In this way, not only can the fixing and holding force of the mounting claws 22 be increased by utilizing the elastic restoring force of the thin-walled portion 23, but also play of the panel mounting parts can be prevented. In particular, if the dimension A from the mounting surface of the panel surface mounting component 23 to the engaging claw portion 22b is set to a negative dimension with respect to the plate thickness B of the game board 4, the effect of the thin portion 23 can be maximized.

As shown in FIG. 5 (A), medium-sized, large-sized board mounting portion product 23 is fixed to the board via a plurality of mounting claws 22. For example, the panel surface mounting component shown in FIG. 5B has mounting claws 22 at four locations, and the panel mounting component shown in FIG. 5C has mounting claws 22 at two locations. When a plurality of mounting claws 22 are formed on one board surface mounting component 23 in this way, the orientation of each mounting claw 22 (direction of the engaging claw portion 22b) is as shown in FIGS. 5B and 5C. It is preferable to disperse appropriately without matching. If it does in this way, the backlash of the panel surface attachment component 23 by the fall of the attachment nail | claw 22 can be prevented.

Next, the removal structure and removal method of the mounting claw 22 will be described. As shown in FIGS. 4 and 6, the attachment claw 22 can be engaged with and received from the removal jig 24 inserted into the attachment hole 4 a from the back side of the game board 4. A removal engagement portion 22c that deforms the attachment claw 22 in the fixing release direction by the pressing force is formed. When such a removal engagement portion 22c is formed, the removal jig 24 is inserted into the attachment hole 4a from the back side of the game board 4 and the removal engagement portion 22c of the attachment claw 22 is simply pushed . As apparent from C), the disengaging operation and the extruding operation of the mounting claw 22 can be performed simultaneously without causing the removal jig 24 to directly contact the back surface of the panel surface mounting component 23 . Thereby, removal of the board surface attachment component 23 can be made easy and the recyclability of a pachinko game machine can be improved.

  It is preferable that the detachable engaging portion 22c is formed in a bridging manner between the pair of mounting claws 22. In this way, not only can the engagement with the removal jig 24 be improved, but also the set of attachment claws 22 are reliably pulled inward by the pressing force of the removal jig 24 to fix the attachment claws 22. Can be canceled. Further, the detachable engaging portion 22c may be a linear connection between the pair of mounting claws 22, but as shown in FIGS. 4 and 6, bend in an inverted U shape or an inverted V shape. Is preferred. If it does in this way, when the removal engagement part 22c is pressed with the jig | tool 24 for removal, the drawing of the attachment nail | claw 22 will become easy.

The shape of the removal jig 24 is not limited as long as it can be inserted into the attachment hole 4a and is narrower than the width between the attachment claws 22 at the time of removal, but it is shown in FIG. Thus, it is preferable to include a recess 24a that engages with the detachment engagement portion 22c. If it does in this way, engagement of the removal jig | tool 24 with respect to the removal engagement part 22c will become reliable, and the removal operation | work of the panel surface attachment component 23 will become easy. Further, as shown in FIG. 7, a plurality of removal jigs 24 can be arranged and used on the jig base 25. That is, if a plurality of removal jigs 24 are erected on the jig base 25 so as to correspond to all attachment claw fixing positions (positions and orientations) on the game board 4, the game board is placed on the jig base 25. By simply setting 4 in a superposed state, it becomes possible to simultaneously disengage all the mounting claws 22 and to remove a plurality of panel surface mounting components 23 simultaneously. In addition, since the jig base 25 of the present embodiment includes a plurality of guide pins 26 that fit into the reference holes 4b formed at the diagonals of the game board 4, the game board 4 can be accurately positioned.

In the pachinko gaming machine 1 according to the present embodiment configured as described, the mounting claws 22 protruding from the board surface mounting component 23 are inserted into the mounting holes 4a of the gaming board 4, and the engagement of the mounting claws 22 with the back side of the gaming board 4 is engaged. Thus, when the board surface mounting component 23 is fixed to the game board 4, the mounting claw can be engaged with the removal jig 24 inserted from the back side of the game board 4 into the mounting hole 4a, and the removal jig. Since the removal engagement portion 22c that deforms the attachment claw 22 in the unlocking direction by the pressing force received from the tool 24 is formed, the removal jig 24 is inserted into the attachment hole 4a from the back side of the game board 4 and attached. By simply pushing the removal engagement portion 22c of the claw 22, as described above, the disengagement operation and the extrusion operation of the attachment claw 22 can be performed without bringing the removal jig 24 into direct contact with the back surface of the panel surface attachment component 23. It can be done at the same time. Thereby, removal of the board surface attachment component 23 can be made easy and the recyclability of the pachinko gaming machine 1 can be enhanced.

Also, if a plurality of removal jigs 24 are used, a plurality of mounting claws 22 can be removed simultaneously, so that even if there are a plurality of claw fixing portions with respect to one board surface mounting component 23 , it can be easily removed. Furthermore, the plurality of panel surface mounting components 23 can be removed simultaneously.

  Further, the mounting claws 22 are formed so as to protrude back-to-back as a pair, and the removal engaging portion 22c is formed in a bridging manner between the pair of mounting claws 22, so that the removal jig 24 is removed. In addition, the set of mounting claws 22 can be reliably tilted inward by the pressing force of the removal jig 24 to release the fixing of the mounting claws 22.

Further, since the mounting claw 22 is integrally formed with the panel surface mounting component 23 via the thin portion 23 a that can be elastically deformed in the mounting hole insertion direction, the mounting claw 22 is utilized by utilizing the elastic restoring force of the thin portion 23. In addition to increasing the fixing and holding force, it is possible to prevent backlash of the panel surface mounting component 23 .
