DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a locking device for a pachinko machine for locking a front frame of a pachinko machine to a main body frame.

[0002]

2. Description of the Related Art Conventionally, as a locking device for a pachinko machine, generally, an operating rod is disposed inside a base frame so as to be able to pivot, and a hook member is provided above and below a support plate of the base frame. The cylinder lock is fixed to the middle part of the mounting plate of the base frame so that the lock shaft can be inserted into the inside of the hole provided in the mounting plate, and operates at the tip of the lock shaft. A locking device having a configuration in which a cam plate that engages with a rod is mounted is used.

[0003]

This type of locking device for a pachinko machine has a strong structure and can reliably perform locking and unlocking operations. However, due to its structure, the locking device is mounted inside the front frame. A hook member of the device protrudes from the inside of the front frame.
For this reason, when packing and transporting the assembly of the front frame, there is a problem that the packaging is difficult and the protruding hook member hits another part during transportation and is damaged.

The present invention has been made in view of the above points, and has no portion protruding from the inside of the front frame, so that the front frame can be smoothly and securely locked / unlocked with respect to the main body frame. An object of the present invention is to provide a locking device for a machine.

[0005]

In order to achieve the above object, a locking device for a pachinko machine according to the present invention is provided with a long frame inside a base frame having a mounting plate and a support plate bent into an L-shaped cross section. The operating rod is arranged to be pivotable, the cylinder lock is fixed to the middle part of the mounting plate, the cam plate is mounted on the lock shaft of the cylinder lock so as to be able to engage with the operating rod, and the mounting plate of the base frame is on the front. In a locking device of a pachinko machine that is attached to the inside of a frame and a receiving bracket is attached to the inside of a main body frame, openings are formed at upper and lower portions of a support plate of a base frame body to allow entry of the receiving bracket. A latch plate having a lock concave portion for restraining the receiving bracket is rotatably supported near the upper and lower openings, respectively, and engagement pins are attached to the upper and lower portions of the operating rod, and the upper and lower latches are provided. The plate is pushed by the bracket and pivots to the latch position. At this time, an engaging portion for engaging the engaging pin of the operating rod to lock at the latch position is formed in a part of the latch plate, biasing the latch plate to the unlocking side, and attaching the operating rod to the locking side. A spring means for biasing is provided and configured.

[0006]

In the locking device having such a structure, when the front frame is closed with respect to the main body frame, the receiving fitting enters the locking recess of the latch plate from the opening, and the receiving fitting pushes the latch plate. The latch plate rotates, and the receiving fitting is restrained in the lock recess of the latch plate. At this time, since the engaging pin of the operating rod is engaged with the engaging portion of the latch plate, the latch plate is held at the latch position, and the receiving member is locked in the lock concave portion of the latch plate to be in a locked state.

When the key of the cylinder lock is turned, the cam plate rotates, and the operating rod engaged therewith moves, whereby the engagement pin is disengaged from the latch plate engaging portion. At this time, the latch plate is rotated by the urging force of the spring, and the locked receiving metal is released from the lock concave portion of the latch plate, pushed out from the opening, and is unlocked.

In this locking device, an opening is formed in a support plate of a base frame, a latch plate is provided near the opening, and a receiving metal fitting which has entered the opening is held in a lock recess of the latch plate to lock the lock. Therefore, when the conventional hook member does not protrude to the rear side of the locking device and the assembly of the front frame is packed and transported, the packing can be easily performed, and the protruding hook member can be provided. Therefore, it is possible to solve a problem such as damage to another portion during transportation.

When a coil spring is hung between the latch plate and the operating rod, the function of urging the latch plate toward the unlocking side and the function of urging the operating rod toward the locking side with one coil spring are provided. Both functions can be provided. Further, if a pin with a sleeve is provided in the receiving fitting, the locking and unlocking can be performed smoothly with reduced friction.
