Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of an underframe angle adjusting device for a pachinko machine.

[0002]

[Prior art]

 Conventionally, each underframe of a pachinko game machine is attached and fixed to a base frame frame called an island of a hole by nailing or the like. That is, the lower rod of the underframe was fixed to the lower island and the upper rod was fixed to the upper island by nails.

[0003]

[Problems to be solved by the device]

 Therefore, adjusting the angle of the underframe in the front-rear direction and exchanging the underframe are very troublesome and time-consuming, and it is impossible to expect proper angle adjustment of the underframe due to the impact. In addition, if the adjustment work is forcibly performed, the island and the underframe will be damaged. Therefore, the present inventor has already researched and devised an underframe angle adjusting device for a pachinko machine, which enables stable fine adjustment of the forward and backward angles of the underside of the pachinko machine by a simple work operation. That is, as shown in FIGS. 5 and 6, the tightening device 3 including the bracket 4 with the clamp bolt 5 for fixing the lower rod 1b of the underframe 1 onto the lower island 2b and the upper portion to the upper island 2a. The lower part of the channel member 6 fitted and fixed was able to move forward and backward along the guide hole 7 of the lower flange 6c, and the web 6a of the channel member 6 was screwed to connect the tip to the slider 8. An angle adjusting screw 9 that controls the forward and backward movement of the slider 8 and a mechanism that fixes the upper rod 1a of the underframe 1 to the slider 8 are operated. An underframe angle adjusting device for a pachinko machine, which is characterized by adjusting an angle. The inventor of the present application has made further studies and has aimed at improving and improving the tightening device and the underframe fixing mechanism corresponding to the corner metal fittings of the underframe which can be placed in the above device.

[0004]

Means for Solving the Problems The present invention has been made in order to solve the above problems, and its gist is to refer to FIGS. 1 to 4 in which the lower rod 1b of the underframe 1 is replaced with the lower island 2b. A tightening device 3 consisting of a bracket 4 with a clamp bolt 5 for fixing the upper part, and a lower part of a channel 6 whose upper part is engaged and fixed to the upper island 2a can be moved back and forth along a guide hole 7 of a lower flange 6c. The slider 8 and the angle adjusting screw 9 for screwing the web 6a of the channel member 6 to connect the tip of the slider 8 to the slider 8 and the upper rod 1a of the underframe 1 are described above. In a device characterized by comprising an underframe fixing mechanism fixed to a slider 8, and adjusting an angle of the underframe 1 in the front-rear direction by operating an angle adjusting screw 9, a tightening device 10 is attached to a bracket 11 of the device. It is possible to swing freely around the 12 pivot screws 15 Further, the underframe fixing mechanism 16 is an angle member made up of a vertical flange 16b provided with an operation long hole 18 having a large circular hole 20 and a long hole 19 up and down, and a horizontal flange 16a provided with a screw long hole 17. This is an underframe angle adjusting device of a pachinko machine in which a contact plate 23 attached to the rear end of the bolt 22 with a lock nut 25 is freely inserted into and removed from the great circular hole 20 and can be raised and lowered.

[0005]

[Effect of device]

 The present invention is as described above, and the lower end of the underframe 1 is pre-tightened and fixed to the lower island 2b by the tightening device 3, and the rotation of the angle adjusting screw 9 that controls the forward / backward movement of the slider 8 is performed. It is possible to perform proper fine adjustment of the front-back direction angle of the underframe with good stability, and easily. Especially, in the device of the present invention, since the bracket 11 of the tightening device 10 can swing around the pivotal screw 15 of the fixture 12, the tightening device 3 which is a corner metal fitting of the underframe 1 and an obstacle such as an out tank can be prevented. You can avoid troubles and obstacles with things. Further, the contact plate 23 attached to the rear end of the bolt 22 with the lock nut 25 can be freely inserted into and removed from the great circular hole 20 of the underframe fixing mechanism 16 and can be moved up and down along the elongated hole 19. Therefore, it can be installed and fixed easily and can withstand long-term use without damaging the island and underframe.
