2. Description of the Related Art For example, in a locking device for a pachinko machine, a hook member is generally rotatably supported on an upper portion and a lower portion of a long base frame, and is slidably disposed in the base frame. The upper and lower hook members are connected by a rod, and a cam plate is attached to a lock shaft of a cylinder lock attached to an intermediate portion of the base frame so as to be able to engage with the connecting rod. With the rotation of the lock shaft of the cylinder lock, the cam plate is rotated. Is rotated and engaged with the connecting rod to slide the connecting rod upward or downward, whereby the upper and lower hook members are tilted and unlocked.

[0003] In addition, a locking device of this type of game machine includes:
A glass frame operating rod or a switch operating rod is slidably disposed between the connecting rod and the support plate near the cam plate in the base frame, and the cam plate is inverted by operating the cylinder lock in a counterclockwise direction. By rotating in the direction, the protruding portion of the cam plate is engaged with the end portion or the step portion of the operating rod, and the operating rod is slid upward or downward.

[0004]

However, as shown in FIG. 6, an actual product has a gap between the connecting rod 31 and the support plate 32 of the base frame due to variations in dimensions during manufacture and warpage of members. In addition, a gap C much wider than the thickness of the operating rod 33 may be generated. In such a case, when the cylinder lock is operated to rotate the cam plate 34 clockwise in the figure and the operating rod 33 is slid downward in the figure, the projection 34 of the cam plate 34 is initially rotated.
a pushes down and moves the operating rod 33 satisfactorily, but near the end of the rotation operation, the inclination of the protruding portion 34 a exerts a force to draw the operating rod 33 inward, and the operating rod 33 moves through the gap C. It shifts to the connecting rod 31 side.

As a result, the operating rod 33 escapes from an appropriate position in the base frame to the inside, and at that position, the operating rod 3
3 stops, the moving rod 33 does not have a proper moving stroke, that is, the moving stroke of the operating rod 33 is short, and the operation of the glass frame locking device and the switch device may be incomplete. Was.

SUMMARY OF THE INVENTION The present invention has been made in view of the above point, and even when the gap between the connecting rod on which the operating rod is provided and the support plate is large, the operation of the cam plate by the operation of the cylinder lock can be prevented. An object of the present invention is to provide a locking device for a game machine capable of causing an appropriate movement stroke of a rod.

[0007]

In order to achieve the above object, a locking device for a game machine according to the present invention comprises a hook member rotatably supported on the upper and lower portions of a support plate of a base frame, and a vertical support member. Are connected by a connecting rod slidably disposed along the supporting plate, and an operating rod for a glass frame or a switch is slidably disposed between the connecting rod and the supporting plate. A cam plate having a protruding portion is fixed to the lock shaft of the cylinder lock attached to the intermediate portion of the frame so as to be engageable with the connecting rod and the operating rod, and when the cam plate is rotated in one direction by operating the cylinder lock. In the locking device for a game machine in which the protrusion is engaged with the operating rod and the operating rod is moved , the protrusion is provided at the base of the protrusion of the cam plate.

[0008]

[0009]

Operation and effect of the present invention In the locking device having such a configuration,
When the key inserted into the cylinder lock is turned in one direction, the cam plate rotates in the same direction, and the protruding portion of the cam plate engages with the operating rod side for the glass frame or the switch and moves it. If the gap between the support plate and the connecting rod is relatively wide due to variations in shape or warpage, the operating rod is likely to be pulled inward at the end of the rotation of the cam plate.

[0010]

However, at the base of the projecting portion of the cam plate, there is provided a projecting portion for preventing the operating rod from retracting toward the connecting rod when the projecting portion is engaged with the operating rod and moved.
Therefore, this can prevent the operating rod from being retracted inside. For this reason, the protrusion of the cam plate

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a rear view of the locking device of the pachinko machine, and FIG. 2 is a left side view thereof. Reference numeral 1 denotes a long base frame, which is formed by bending the mounting plate 2 and the support plate 3 into a substantially L shape in plan view. Hook members 4 are pivotally supported on the upper and lower portions of the support plate 3 of the base frame 1 around the pins 4a, and can be tilted downward.

A wide part is formed in the middle of the mounting plate 2 of the base frame 1, and a cylinder lock 5 is inserted into the base frame 1 from the front side at substantially the center of the wide part. Installed with. The cam plate 6 is attached to the tip of the lock shaft. The cam plate 6 is provided with a first protrusion 6a and a second protrusion 6b.

The hook members 4, 4 pivotally supported on the upper and lower portions of the support plate 3 of the base frame 1 are connected by a single connecting rod 7 via a pin 7a. The connecting rod 7 is arranged along the support plate 3, and is bent and arranged so as to expand outward together with the support plate 3 in a wide portion of the mounting plate 2. An engaging portion (in this case, a modified elongated hole) is provided at a position corresponding to the cam plate 6 of the connecting rod 7, and when the key inserted into the cylinder lock 5 is turned clockwise,
When the second protruding portion 6b rotates counterclockwise in FIG. 1, it engages with the engaging portion and slides the connecting rod 7 upward. A coil spring (not shown) is hung between the connecting rod 7 and the mounting plate 2, and the connecting rod 7 is constantly urged downward by the coil spring.

Between the support plate 3 and the connecting rod 7, a glass frame operating rod 8 for unlocking the glass frame locking device is disposed so as to be vertically slidable. Normally, the space between the support plate 3 and the connecting rod 7 is
Although the width is slightly wider than the thickness of the operating rod 8, a relatively wide gap C may be formed due to variation in the shape of the connecting rod 7 or warpage. FIG. 1 illustrates such a case.
The glass frame operating rod 8 is provided with an operating piece 8a that engages with an unlocking lever of a glass frame locking device (not shown) so as to protrude outward from the opening 3a of the support plate 3.

Further, a protrusion 8b for preventing retraction is provided below the operating piece 8a, that is, on the side that moves during operation. When the glass frame operating rod 8 is moved downward by the operation of the cylinder lock, the protrusion 8b for sliding prevention comes into sliding contact with the outside of the support plate 3 and the operating rod 8 retracts inward (moves toward the connecting rod 7). ).

The lower portion of the glass frame operating rod 8 and the mounting plate 2
And the glass frame operating rod 8 is urged upward by the coil spring 9. When the cam plate 6 is rotated clockwise in FIG. 1 by operating the cylinder lock 5, the first protrusion 6a of the cam plate 6 hits the upper end of the glass frame operating rod 8 and pushes it down. Further, a guide portion 8c for guiding the vertical movement of the glass frame operating rod 8 is provided on the upper end portion thereof by bending outward.

Next, the operation of the above-structured locking device will be described. The locking device is mounted inside a front frame which is openably and closably mounted on a front surface of a main frame of the pachinko machine. In the main body frame, a receiving fitting to which the hook member 4 is locked is attached at a corresponding position. A metal frame is mounted in the front frame, and a glass frame is openably mounted in the metal frame. The glass frame lock is mounted on the metal frame, and the operating piece 8a of the glass frame operating rod 8 is positioned opposite to the unlocking lever of the glass frame lock.

When the front frame is closed with respect to the main frame of the pachinko machine, the upper and lower hook members 4 of the locking device return to the horizontal position while tilting against the receiving metal fittings and are locked there. To unlock the front frame, turn the key inserted into the cylinder lock clockwise. Thereby, the cam plate 6 rotates counterclockwise in FIG. 1, and the second protruding portion 6b of the cam plate 6 engages with the engaging portion of the long hole of the connecting rod 7 to push it up. Due to the upward movement of the connecting rod 7, the upper and lower hook members 4 tilt the tips of the upper and lower hook members 4a about the pins 4a, thereby releasing the engagement with the receiving bracket and unlocking the front frame.

On the other hand, when the key inserted into the cylinder lock is turned to the left, the cam plate 6 rotates clockwise in FIG. 1, and the first protrusion 6a of the cam plate 6 is moved from the long hole of the connecting rod 7 to the operating rod. 8 and engages with the upper end of the glass frame operating rod 8 and pushes it down. The glass frame operating rod 8 moves downward against the urging force of the coil spring 9, but the gap between the support plate 3 and the connecting rod 7 is relatively large due to the variation in the shape of the connecting rod 7 and the warp. In this case, as shown in FIG. 4, the glass frame operating rod 8 is easily pulled inward at the end of the operation of pushing down the cam plate 6.

However, a projection 8b for preventing retraction is provided below the operating piece 8a, and when the projection 8b moves downward, the projection 8b comes into sliding contact with the outside of the support plate 3 so that the operating rod 8 moves inward. Retracting (moving to the connecting rod 7 side) is prevented. For this reason, the first projecting portion 6a of the cam plate 6 surely pushes down the glass frame operating rod 8 to the end, and the operating piece 8a pushes down the unlocking lever of the locking device for the glass frame (not shown) to a predetermined position. Can be unlocked reliably.

FIG. 5 shows another embodiment. In this example, a protrusion 26 c for preventing the retraction of the glass frame operating rod 28 is provided on the cam plate 26 side. That is, the protrusion 26 c for preventing retraction is provided as a semicircular protrusion on the rotation side of the base of the first protrusion 26 a of the cam plate 26.

When the key inserted into the cylinder lock is turned counterclockwise, the cam plate 26 having such a structure is rotated clockwise in FIG. It enters the operating rod 28 through the hole, engages with the upper end of the glass frame operating rod 28, and pushes it down.

At this time, at the end of the push-down operation due to the rotation of the cam plate 26, the glass frame operating rod 28 is turned inside (the connecting rod 7).
Side), the upper end of the glass frame operating rod 28 hits the semicircular retraction preventing projection 26c at the end of the pressing operation of the cam plate 26, and is pressed down as it is. Therefore, the inward movement of the glass frame operating rod 28 is prevented, and the rotation of the cam plate 26 allows the glass frame operating rod 28 to be pushed down to the appropriate stroke position.

In the above embodiment, the locking device of a pachinko machine has been described as an example. However, the present invention can also be applied to a locking device of a pachislot machine. In this case, the operating rod is a switch for operating a reset switch or the like. Operating rod.
