Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a locking device for a pachinko machine that opens and closes a front frame and a glass window frame of the pachinko machine.

(Prior Art) Rotating a key inserted in a lock in the forward direction opens the front frame from the wooden frame, and rotating the key in the reverse direction opens the glass window frame from the front frame. The locking device for a pachinko machine is already known from Japanese Utility Model Publication No. 57-8867.

(Problems to be solved by the invention) However, such a conventional locking device for a pachinko machine is
There is a problem that when the front frame is opened, a plurality of locking claws having an acute tip and the operating piece of the glass window frame are projected outward to hinder the work of the clerk and are dangerous.

(Means for Solving the Problems) The present invention relates to a locking device for a pachinko machine that solves the above-mentioned problems, and is a pachinko machine in which a glass window frame is pivotally attached to a front frame that is hinged to a wooden frame. In the machine, install L-shaped locking claws on the top and bottom of the side edge of the glass window frame,
On the inner edge of the front frame, a slidable locking plate with notches for hooking the locking claws is provided biased by a spring, and an inverted L-shaped locking is provided on the inside of the front frame. In addition to mounting the claws, a slidable locking plate with notches for locking the locking claws on the top and bottom of the wooden frame is urged by a spring, and a lock is attached to the front frame. The rotary shaft of the lock is provided with a rotary claw that comes into contact with the engaging projection of the locking plate.

(Operation) In such a locking device for a pachinko machine, when the glass window frame is opened, the key is inserted into the lock and rotated counterclockwise so that the rotary claw attached to the rotary shaft of the lock is released. Since the locking plate on the front frame side is pushed down against the biasing force of the spring by coming into contact with the engaging projection, the notch of the locking plate also moves downward, and the L-shaped locking claw is not locked to the notch. When unwound, the glass window frame is opened. Also, when the key inserted in the lock is rotated clockwise, the other rotating pawl attached to the rotating shaft of the lock comes into contact with the engaging projection and resists the urging force of the spring. Since the locking plate on the frame side is pushed down, the notch of the locking plate also moves upward, the engagement of the notch of the inverted L-shaped locking claw is released, and the front frame is released from the wooden frame.
