Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a locking mechanism for locking the base frame and front frame of a Pachinko machine in a closed position.

[Conventional technology]

A game board is fixed to a base frame attached to a machine frame body or an island stand installed in a pachinko parlor. The base frame can be opened and closed relative to the machine frame body in order to install the game board and inspect and maintain the back mechanism. In addition, on the front side of the base frame,
A glass frame holding a front glass that covers the game board is attached so that it can be opened and closed. Since the surface of the game board is exposed by opening the glass frame, it becomes possible to easily adjust balls that are jammed or obstructing nails on the surface of the game board.

In this way, the base frame of a pachinko machine can be opened and closed relative to the machine frame itself, and the glass frame can be opened and closed relative to the base frame, but these must be securely locked during normal play. No.
Various types of locking devices for this purpose have been proposed and used in the past, but all of them require a large number of different parts, resulting in complex structures and troublesome manufacturing and assembly. . Furthermore, as the structure becomes more complex, there are problems such as frequent malfunctions and poor durability.

[Problem that the invention attempts to solve]

The present invention has been made in view of the problems of the prior art, and aims to provide a locking device for a Pachinko machine that reduces the number of parts and has a simplified structure.

[Means for solving problems]

In order to solve the above problems, this invention has a base plate fixed to the base frame, one side of which engages with the locking part of the machine frame body, and the other side of which engages with the locking part of the front frame. Two types of hook members having different shapes are rotatably attached to the base plate, and two operating members having the same shape are provided on the base plate and are moved in opposite directions to operate these hook members separately. . Each actuating member is urged in opposite directions by a biasing member, and the actuating member and the hook member are connected by a connecting lever having the same shape. A pressing part is formed on each operating member, and when the key inserted from the front of the base frame is rotated,
Depending on the direction of rotation, the release pin selectively presses one of the pressing parts and moves one of the operating members in the release direction against the bias, thereby locking the hook member via the connection lever. It is structured so that it can be separated from the department.

Hereinafter, one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[Configuration of Example]

In FIG. 2 showing the appearance of a pachinko machine using the present invention, after a game board (not shown) is fixed to the opening 2, the base frame 1 is attached to the machine frame body 3 by a known means so as to be openable and closable. . Further, a front frame 5 holding a front glass 4 is attached to the base frame 1 so as to be openable and closable. This front frame 5 is an integrated structure that includes a conventional glass frame into which a front glass is fitted, and a conventional front plate equipped with an upper plate that stores prize balls and sends the pachinko balls one by one to the firing device. It is configured as.

A base plate 8 is fixed to one side of the base frame 1, and a locking device 10 is attached to this base plate 8. As will be described later, the locking device 10 includes a first hook 12 that engages with a locking metal fitting 11 fixed to the machine frame main body 3, and a second hook that engages with a locking metal fitting 14 fixed to the front frame 5. 15. A pair of each of these first and second hooks is provided.

Insert the key 18 (see Figure 1) into the key insertion part 16 provided exposed on the front side of the base frame 1, and turn it to the right (counterclockwise in Figure 1). , the tips of the second hooks 15 are lowered and disengaged from the locking fittings 14. This allows the front frame 5 to be released from the base frame 1. Further, when the key 18 is rotated to the left (clockwise in FIG. 1), the tips of each of the first hooks 12 are raised and disengaged from the locking fitting 11. This allows the base frame 1 to be released from the machine frame body 3.

When closing the base frame 1, attach the base frame 1 to the machine frame body 3.
When the locking fitting 11 is pushed toward the

engage with. Similarly, by pushing the front frame 5 into the base frame 1 by a certain amount, the second hook 15 engages with the locking metal fitting 14, so that the front frame 5 is closed.

In FIG. 1 showing the lock device 10, a base plate 8 fixed to the base frame 1 has a rising surface 9 extending along the opening/closing direction of the front frame 5. As shown in FIG. A pair of guide pins 20 are provided on this rising surface 9, penetrating to the back surface side and protruding. On both sides of the rising surface 9, operating levers 25 and 26 are slidably supported, each having slots 23 and 24 through which the guide pin 20 is inserted.

A connecting lever 28 is pivotally attached to both ends of the operating lever 25. Further, one end of the first hook 12, which is rotatably attached to the base plate 8 by a pin 30, is fixed to the connecting lever 28. Similarly, a connecting lever 32 is pivotally attached to both ends of the operating lever 26. Further, one end of the second hook 15, which is pivoted to the base plate 8 by a pin 33, is pivoted to the connection lever 32.

The actuating lever 25 and the actuating lever 26 each have springs 35 and 3 suspended between them and the base plate 8.
6, one is biased upward and the other is biased downward. When the actuating levers 25, 26 are in their initial positions due to the springs 35, 36, the first hook 1 is closed as shown in the figure.
2. Each of the second hooks 15 is in the locked position and engaged with the locking fittings 11 and 14.

The operating lever 25 has a release piece 38 and an operating lever 2
A release piece 39 is fixed to each of the holes 6 by caulking or the like. The end of the release piece 39 of the operating lever 26 passes through the slit 40 of the base plate 8 and is located above the release piece 38. A release pin 43 protrudes between these release pieces 38 and 39 and is planted on a rotating plate 42 that is rotated by operating the key 18. Note that a manual release lever 45 is fixed to the actuation lever 26. Also,
Reference numeral 46 indicates an opening spring fixed to the base frame 1, which is charged when the front frame 5 is closed with respect to the base frame 1, and biases the front frame 5 in the opening direction.

[Effect of the embodiment]

From the initial state shown in FIG.
When the key 18 is inserted and rotated to the right (counterclockwise in FIG. 1), the release pin 43 pushes up the release piece 39. As a result, actuation lever 2
6 resists the biasing force of the spring 36, and the guide pin 2
0. Slide upward while being guided by the slot 24. Then, the tip ends of the pair of second hooks 15 descend around the shaft 33 and are disengaged from the locking fittings 14. As a result, the lock between the base frame 1 and the front frame 5 is released, so that the front frame 5 is pushed out by the opening spring 46 and opened. Note that when the locking metal fitting 14 and the second hook are in the locked state, the opening spring 46 presses the front frame 5, so that the engagement between the locking metal fitting 14 and the second hook 15 is prevented with no play. It will now be closely maintained.

When the key 18 is rotated to the left (clockwise in FIG. 1), the release pin 43 pushes down the operating lever 25. As a result, the tip end of the second hook 12 rises around the shaft 30, so that the engagement with the locking metal fitting 11 is released, and the lock between the base frame 1 and the machine frame main body 3 is released. Therefore, the base frame 1 can be opened. Note that if it is desired to open the front frame 5 after opening the base frame 1, the manual release lever 45 may be pulled up instead of operating the key 18 again.

According to the above configuration, the first hook 12 and the second hook 15, as well as many of the members for operating them, have similar shapes, except that the directions of movement are reversed. . Therefore, not only can the number of parts be saved, but also the types of parts can be reduced by making parts common. Note that the present invention can also be used in conventional pachinko machines in which the glass frame and front plate are separate pieces.

[Effect of idea]

As explained above, according to the present invention, the main part of the locking device that locks the machine frame body and the base frame and the base frame and the front frame is attached to the base frame, and the two types of locks described above are installed. Since each member for performing the operation is linked to an operating member that moves in opposite directions when the opening operation is performed, each member and the interlocking mechanism can be constructed symmetrically. As a result, compared to conventional devices of this type, the configuration becomes simpler and the reliability of operation can be improved.
