Description

[Detailed description of the invention] This invention is installed opposite to the launch guide rail that guides the balls of a pachinko machine to the gaming section, and is used to guide and manipulate balls that are illegally sent into the gaming section from the outside or to win prizes. The present invention relates to a protective cover that prevents unauthorized acts such as operating a device, and also effectively avoids damage to glass caused by collisions between shot balls on a rail.

As is well known, pachinko machines are designed to prevent players from operating the prize ball ejecting device through fraudulent acts, or from operating prize winning devices such as the prize opening when no winning balls are flying into the machine. Although various means have been devised, fraud against the gaming club is easy to commit because the gaming board surface can be seen through the glass, and in the gaming club, the purpose is to guide the falling balls to the prize opening. Because they can be distant relatives, the club is susceptible to fraud.

In many cases, this fraudulent act against the gaming club involves inserting a wire such as piano wire through the gap between the metal frames of the glass.
It is normal to pass the ball between obstacle nails installed in the gaming area to guide the falling ball to the winning hole, or to directly open the winning hole with the end of the wire to make it easier to win.In this case, the above-mentioned method is used. Since the game area is surrounded by a rail that guides the shot balls and a rail that surrounds the game area, the wire must be inserted between these rails and the glass that closes the front surface.

In particular, this type of fraud is carried out in a discreet manner by inserting a wire from below the gaming section.

For this reason, in order to prevent fraud, conventionally a plastic barrier plate was attached to the launch guide rail to prevent the wire inserted as described above from further intruding at the rail position. The tip of the lever plate was brought into contact with the back of the glass to close the gap between the rail and the glass and prevent the wire from entering.

However, the gap between the rail and the glass plate is not always constant due to manufacturing errors, so in order to always completely close the gap, the contact plate needs to be flexible to absorb this error. In some cases, wires were forcefully inserted through the parts.

In view of the shortcomings of the conventional tamper-prevention barrier plate, the present invention eliminates these and provides a more complete tamper-prevention measure. The purpose of the present invention is to provide a protective cover that protects glass from collisions between balls and prevents damage to the glass.

Hereinafter, embodiments illustrating the present invention will be described.
The figure is a partially cutaway front view of the main parts of the protective cover of the present invention in its used state, and the reference numeral 1 shown in the drawing is a game board forming the game section 2, and 3 is the front side of this game board. 4 is a guide rail that is attached to and surrounds the game section 2, and 4 is a launch guide rail that is attached in parallel to the outside of this guide rail and that guides a shot ball (hit ball) launched from a launcher (not shown) to the game section 2. 5 is a protective cover according to the present invention attached along this launch guide rail.

The game board 1 shown in this embodiment is shown as a game board for a so-called detachable pachinko machine, and is therefore placed on a fixed plate 6 that is fixedly housed in the pachinko machine body, as is known. The hook provided on this fixing plate 6 is designed to be detachably attached by locking with a metal fitting 7.

As shown in the figure, the guide rail 3 and the launch guide rail 4 are fixed to the game board 1, and the other launch guide rail 4' that guides the ball launched from the launcher to the launch guide rail 4 is a fixed plate. 6, and a foul ball opening 8 opens at the connecting portion of both firing guide rails.

Now, the protective cover 5 attached to the launch guide rail 4 provided in this way is a mounting plate piece 5 attached to the outer peripheral surface of the rail.
a, a cover piece 5b extending approximately at right angles along one side edge of the mounting plate piece, and a small contact protrusion 5d extending in the opposite direction from the base end of the cover piece. Consists of protrusion 5C,
A fixing piece 5e for fixing the protective cover is integrally provided on the mounting plate piece 5a.

The mounting plate piece 5a, the cover piece 5b, and the small projecting piece 5C are integrally molded from synthetic resin, especially transparent synthetic resin. When the cover piece 5b is attached along the outer peripheral surface with a width slightly larger than the width of the rail 4, one side edge on which the cover piece 5b is provided is formed so as to slightly protrude forward from the side edge of the rail.

The cover piece 5b extending from the mounting plate piece extends substantially at right angles beyond the edge of the rail 4 so as to cover the firing passage 9 on the rail 4, and the base end thereof, that is, the cover piece 5b The small projecting piece 5C extending in the opposite direction from one side edge is made to protrude smaller than this, and an abutting convex portion 5d is provided on the front surface thereof.

Although the length of this protective cover 5 is not specified, it is formed to a required length along the launch guide rail 4 because it prevents wire rods from entering and protects the glass from collisions with batted balls, as described above. Therefore, in this embodiment, the mounting plate piece 5a is formed with a length that can cover the lower half of the rail 4, and the cover piece 5b and small protruding piece 5C are attached to the length of the mounting plate piece 5a. It should be formed over the entire length of the blade.

The abutting convex portions 5d provided on the small protruding pieces 5C are similarly arranged to match the length of the small protruding pieces 5C.

This protective cover covers the launch guide rail 4 as shown in Figure 1.
A mounting plate piece 5a is placed in contact with the outer peripheral surface of the rail 4, and a cover piece 5b is projected upward beyond the rail 4 to cover the front surface of the firing passage 9.

Then, the game board 1 is inserted through the nail hole 10 provided in the fixed part 5e.
Nails 11 are driven to fix the parts.

The protective cover installed in this way appears to be installed in an unstable state, but the reason is that the mounting plate 5a is attached to the rail 4, and as the glass 12 is closed, the back surface of the protective cover is attached to the small protrusion 5C. Since it abuts against the abutment convex portion 5d provided on the screen, it is sandwiched between the glass and the game board and fixed in a stable state.

Figures 3 and 4 show the above state, and show that when the glass 12 is closed, the contact convex portion 5d comes into contact with the back surface of the glass 12, making the protective cover stable, but at the same time, due to this contact, the glass The gap between the rail 4 and the rail 4 will be completely closed.

FIG. 4 shows a case where the distance between the glass and the game board 1 is narrower than that shown in FIG. The protruding piece 5C bends and absorbs the approach, and the cover piece 5b extending upward is turned outward (glass side) with the base end as a fulcrum.
It will curve and come into contact with the back of the glass.

Therefore, according to the present invention, when the glass 12 is closed, the abutment convex portion 5d of the protective cover comes into contact with the back surface of the glass and closes the gap between the glass and the rail, thereby preventing the insertion of wire rods and the like. As shown, the small protruding piece 5C protrudes downward from the mounting plate piece to form a jaw, so the wire inserted from below can be blocked by this jaw, and extremely accurate fraud prevention is expected. can.

At the same time, the protective cover of the present invention has cover piece 5b.
As a result of protruding and covering the front of the firing path 9, even if the fired ball and the rebound ball collide on this path, they are prevented from directly colliding with the glass, effectively avoiding damage. can do.

It is desired that at least the cover piece 5b is made of transparent synthetic resin in order to make the shooting state of the shot ball visible.

By the way, the illustrated embodiment shows an example of the present invention, but when implementing it, the abutment convex portion 5d is formed to be somewhat higher, taking into account some error in the distance between the game board and the glass. However, if the cover piece 5b is always brought into contact with the back surface of the glass in a crimped state as shown in FIG. This is effective because it eliminates the possibility of obstructing the path of the shot ball.

Further, as shown in the figure, if a hook 13 is integrally provided on the fixed piece 5e of the protective cover and a nail hole 10 is provided in the thick part of this hook, the hook for fixing the game board 1 will lock the metal fitting 7. There is no need to prepare a separate hook, which makes manufacturing pachinko machines easier, and
This also means that parts can be omitted, which is advantageous in terms of manufacturing.

Note that the protective cover of the present invention is not limited to the locations shown in the drawings, but may be attached to any location on the rail, and the range is not particularly restricted.
