Description

[Detailed description of the invention] This invention relates to the improvement of a locking device for the window frame of a pachinko machine.The purpose of this invention is to lock the glass window frame of a pachinko machine and to lock the locked state. The purpose is to prevent unauthorized unlocking of the machine.

Next, an embodiment of the present invention will be explained according to the drawings. In the drawing, 1 is a machine frame of a pachinko machine, 2 is a game board, 3 is a front frame of the machine frame 1, and 4 is attached to the front frame 3. It is a window frame.

Reference numeral 5 denotes a glass window frame which is pivotally attached to the window frame 4 so that it can be fanned out, and double-glazed glasses G, G are fitted therein.

Reference numeral 6 denotes a base piece attached to the inner surface of the open side of the window frame 4, and escape holes 1°T are opened in the upper and lower parts of the base piece.

Reference numeral 8 denotes an engaging piece having a pin 9 attached to the base piece 6 so as to be able to swing around the middle part thereof, and a front stopper 8a is provided vertically in the drawing near the lower part of the front side of the engaging piece 8, and a front stopper 8a is provided near the middle part of the back side of the engaging piece 8. A rear stopper 8b is provided to protrude vertically as shown in the figure.

This rear stopper 8b can come into contact with a part of the back surface of the glass window frame 5 when the door is locked.

Reference numeral 10 denotes a movable lock piece that is arranged in parallel to the base piece 6 so as to be able to move up and down, and has diagonal guide holes it and 11 penetrated through its upper and lower parts, and guide pins 12 above and below the base piece 6. A recess 10a is provided near the middle of the movable lock piece 10, and a protrusion 10b is provided at the lower end of the recess 10a.

The receiving portion 13 is bent horizontally from the lower end of the protruding portion 10b.

The engaging grooves 10c, 10c are opened at the upper and lower parts of the movable lock piece 10, and upper and lower locking claws 14, 14 are formed, respectively.

Note that guide edges 14a and 14b are obliquely formed above the both-side matching grooves 10c and on both the locking claws 14, respectively.

Reference numeral 15 denotes a release lever formed in a substantially L-shape, the base of which is rotatably attached to a pin 16 near the middle part of the movable lock piece 10, and a retaining piece is attached to the front edge of the upper end piece. 8
A hook portion 15a is formed to be removably engaged with the front stopper 83, and its lower end piece serves as a release handle 15b.

11 is a spring that biases the release lever 15 counterclockwise.

The engagement between the front stopper 8a of the engagement piece 8 and the hook portion 15a of the release lever 15 is maintained.

Reference numerals 18 and 18 denote locking devices disposed on the upper and lower sides of the glass window frame 5, from which projecting pieces 18a and 18a are provided, respectively, and the movable lock piece 10 is inserted through the escape hole 1 of the glass window frame 5. can be engaged with the engagement groove 10C.

Reference numeral 19 denotes a cylinder lock of this example, and its operating panel 20 is rotatable in the direction shown in the figure or in the R direction.

Reference numeral 23 denotes a movable piece that is moved up and down by the first operation piece 21 of the operation panel 20, and its projecting piece 23a is linked to the handle 15b.

Reference numeral 24 denotes a release piece that is moved up and down by the second operation piece 22 of the operation panel 20, and is capable of unlocking or locking the front frame 3.

Next, the operation and effects of the embodiment having the above configuration will be explained.

First, the case of unlocking the closed glass window frame 5 will be explained. In this case, when the cylinder lock 19 is operated with a key and the handle 15b is pushed down via the interlocking piece 23, the release lever 15 is moved clockwise. The movable lock piece 10 is moved down against the spring 1γ while the hook portion 15a of the release lever 15 is released from the front stopper 8a of the engagement piece 8 (see the chain line in FIG. 4). , the locking pawl 14 of the movable lock piece 10 is released from the locking tool 18.

On the other hand, since the retaining piece 8 is urged by the spring 11 and rotated clockwise, the glass window frame 5 is pushed out and opened by the rear stopper 8b of the retaining piece 8.

Next, a case will be explained in which the opened glass window frame 5 is closed in the opposite manner to the above. In this case, when the glass window frame 5 is closed while being pressed, the protrusions 18a and 1 of the hanging tool 18
Since the movable lock piece 10 is pushed by being guided by the upper and lower guide edges 14a and 14b of the lock piece 10, the release lever 15 is automatically locked at the same time as the glass window frame 5 is locked.
The engagement state with respect to the engagement piece 8 is locked.

Therefore, when the engagement between the release lever 15 and the engagement piece 8 is locked, for example, a piano wire or the like may be inserted and hooked onto a part of the movable lock piece 10, and the movable lock piece 10 may be illegally lowered. Even if an attempt is made to do so, the movable lock piece 10 is prevented from moving downward, which has the effect of preventing unauthorized unlocking from the front side of the Pachinko machine.

That is, in the present invention, in particular, a retaining piece for locking the hook portion at the upper end of the release lever when locking the glass window frame is swingably pinned to approximately the middle portion of the base piece. This is an extremely practical idea as a locking device for a window frame in a pachinko machine, which has the effect of ensuring the locking of the glass window frame and preventing unauthorized opening of the glass window frame.

In the above embodiment, instead of the integrally formed release lever 15, a release lever may be used in which the handle 15b is pinned to the base so that the handle 15b can be raised and lowered.
