Description

[Detailed description of the invention] The present invention relates to a supply ball blocking device that is activated by attaching and detaching a ball counter to and from a fixed plate attached to a frame supporting a pachinko machine, and its purpose The reason for this is that by attaching and detaching the ball counter to and from the fixed plate, it is possible to easily mechanically and easily prevent the supply balls from flowing down.

Conventionally, various improvements have been made to the connectors that connect the coil spring flexible tube and the ball conduit section of the ball counter in the supply path from the pachinko ball supply source to the tank of each pachinko machine. However, if it becomes necessary to remove the ball counter due to malfunction or other reasons, place coins or other flakes in the coil spring flexible tube to prevent the balls from flowing down from the pachinko ball supply source. This required manual operations such as interposing the wire between the coil wires.

The present invention was devised in view of these points, and is designed to prevent falling pachinko balls mechanically and easily, instead of using manual operations.

That is, a pachinko ball guide protrusion attached to a fixed plate, a ball blocking piece attached to the fixed plate and urged to fit into the guide protrusion, and a ball counter that is detachable from the fixed plate. and a ball conduit section that is provided on the ball counter and that fits into and disengages from the guide protrusion when the ball counter is attached and removed, and when the ball conduit section is fitted into the guide protrusion, When the outer periphery of the ball conduit prevents the ball blocking piece from fitting into the guide protrusion and the ball conduit is detached from the guide protrusion, the ball blocking piece moves into the guide protrusion due to the above-mentioned bias. This device constitutes a replenishment ball blocking device that is operated by attaching and detaching a ball counter that is fitted into the ball counter.

Embodiments of the present invention will be described below with reference to the drawings.

The device of the present invention includes a holder a that holds a coil spring flexible tube 1 for replenishing pachinko balls from a replenishment source;
It consists of a fixed plate A having a stopper b for balls flowing down from the coil spring flexible tube 1, and a ball counter B which is detachable from the fixed plate A and has a ball pipe passage c. It is something.

The fixed plate A has a cut-and-raised protrusion 3 on one side for attachment to the frame 2 that supports the pachinko machine, and a coil spring flexible tube 1 fixed above the cut-and-raised protrusion 3. A holder a for holding the holder protrudes from the other side.

As shown in FIG. 5, this holder a has two elastic clamp pieces 5, 5' facing each other around a fixing piece 4 fixed to the fixing plate A, and the clamp pieces 5, 5' are The middle part thereof bulges outward 6, 6', and the tip part 7, 7' opens outward. The upper edges of the bulges 6, 6' have locking protrusions 8, 8' that lock the coil spring flexible tube 1 facing inward, and the lower edges have locking protrusions 8, 8' that are slightly biased inward and downward. Opposite guide protrusions 9, 9' are provided, and the guide protrusion 9 is provided with a groove 10 on the lower side.

Further, the fixed plate A is provided with a ball stopper b on the left side of the holder a. This is made up of a blocking piece 13 that is resiliently pushed by a spring 12 onto a U-shaped frame 11 fixed to a fixed plate A. It can pass through the groove 10 of the protruding piece 9,
Its lower edge has an inclined surface 14 that slopes downward.

Further, on the fixing plate A, bag-shaped punched protrusions 15, 15' are provided at positions corresponding to each corner of the rectangle;
16, 16' are provided.

The ball counter B has a mechanism section 17 and a ball conduit section c attached to a support plate 18, and the ball conduit section c is a cylindrical section 19 whose upper part is enlarged. The lower part is a square tube part 20, and a cut part 21 is provided from the upper part to the lower part over the entire length.
A ball counting wheel 22 fixed to a shaft extending from the inside of the mechanism section 17 is provided in the cut section 21 .

Specifically, the device of the present invention has the above-mentioned configuration, and a coil spring for replenishing pachinko balls is attached to the holder a protruding from the fixed plate A fixed to the frame 2 that supports the pachinko machine. To hold the flexible tube 1, attach the lower end of the coil spring flexible tube 1 to the clamp piece 5 of the holder a,
When pushed in from the tips 7, 7' of the coil wires 5' to the bulges 6, 6', the locking protrusions 8, 8' bite between the coil wires and are locked.

To attach ball counter B to fixed plate A,
As shown in Fig. 4 and Fig. 3, the support plate 1 of the ball counter B
The corner part of the upper edge of 8 is raised inside the bag-shaped punched protrusions 15, 15' protruding from the fixing plate A, and the corner part of the lower edge exceeds the bag-shaped punched protrusions 16, 16'. By lowering it, the support plate 18 is locked into the bag-shaped punched protrusions 15, 15'; 16, 16' of the fixing plate A.

At this time, the cylindrical part 19 at the upper end of the ball conduit part C of the ball counter B is connected to the guide protrusions 9, 9' of the holder a.
The guide protrusions 9 and 9' are inscribed in the cylindrical portion 19 and the axes of the coil spring flexible tube 1 and the ball tube section c are aligned, and the coil spring flexible tube 1, the inner surfaces of the guide protrusions 9 and 9', and the inner wall of the rectangular tube section 20 of the ball conduit section c are on the same plane, forming a flow path that does not hinder the flow of the balls.

On the other hand, as the ball conduit section c rises, the edge 23 of the upper cylindrical section 19 moves the blocking piece 13, from which the falling ball blocking device b provided on the fixed plate A has advanced, to its inclined surface 14. The distal end portion of the blocking piece 13 is brought into contact with the outer surface of the cylindrical portion 19 of the ball conduit portion c.

During use under such conditions, ball counter B
If it becomes necessary to remove the ball counter B from the fixed plate A due to its failure, replacement, or other reason, when the support plate 18 of the ball counter B is raised, the corner of the lower edge of the support plate 18 will be removed from the fixed plate A. Since it escapes from the bag-shaped punched protrusions 16, 16', it can be removed by pulling down the support plate 13. In this case, the blocking piece 13, which is spring-loaded by the spring 12,
At the same time that the balls are removed from the guide protrusions 9, 9' of the holder a, they advance below the lower end of the coil spring flexible tube 1 through the grooves 10 of the guide protrusions 9, thereby blocking the balls from flowing down.

In addition, the coil spring flexible tube 1 is held by its holder a.
If it becomes necessary to remove the coil spring flexible tube 1, it can be removed by pulling the lower end of the coil spring flexible tube 1 in the direction of the tips 7, 7' of the clamp pieces 5, 5' of the holder a. can.

As explained above, in the present invention, the blocking piece that prevents pachinko balls from flowing down is urged to advance from the fixed plate side toward the ball conduit section of the ball counter that is detachable from the fixed plate. Therefore, if it becomes necessary to remove the ball counter from the fixed plate due to failure, replacement, or other reasons, by removing it,
The blocking piece advances below the lower end of the coil spring flexible tube for replenishing balls to block the falling balls, and the blocking piece is retreated to its original position at the upper edge of the ball conduit section of the ball counter. , the coil spring flexible tube and the ball pipe line of the ball counter will be communicated, and artificial measures such as inserting coins or thin pieces between the coil wires of the coil spring flexible tube as in the conventional method will be avoided. Compared to those that require manual operation, it is possible to mechanically easily connect the pachinko ball flow path and prevent the pachinko balls from flowing down by simply attaching and detaching the ball counter to the fixed plate. Its operation is reliable and completely hassle-free.
