Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a variable winning device for a ball game machine such as a pachinko machine. More specifically, the invention is rotatable on a game board surface of the ball game machine. The present invention relates to a variable winning device having a pair of movable wing pieces attached.

[Prior Art] For example, a variable winning device called a tulip is used in a pachinko gaming machine. This is because when a pair of movable blades 2L and 2R are standing up as shown in FIG.
Forming a winning opening in which only one game ball 1 can be won, and when the pair of movable wing pieces 2L and 2R are tilted as shown in FIG. 4, the game ball 1 becomes an easy winning hole. . That is, by rotating the pair of movable wing pieces 2L and 2R, the game ball 1 driven on the game board surface is converted into a standing state where it is difficult to win a prize and an inclined state where it is easy to win a prize.

This variable winning device has a mounting plate 3 mounted on the game board surface and a pair of movable wing pieces 2L, 2 mounted on the front side thereof.
And a front cover 4 that functions as a support member for the R, and a pair of shaft pins 5L, 5R that are spaced apart from the back surface of the front cover 4 and project rearward are provided in the movable wing pieces 2L, 2R. By inserting into 6R, each movable wing piece 2L, 2R is rotatably supported.

The front cover 4 is fixed to the mounting plate 3 with screws or the like. The front part of the front cover 4 is formed as a decorative plate, and the lower part of the front cover 4 is in a state in which both of the movable wings 2L and 2R are tilted open when tilted as shown in FIG. Formed to stop.

[Problems to be solved by the invention] However, in the conventional variable winning device as described above, the shaft pins 5L and 5R that rotatably support the movable wing pieces 2L and 2R are provided.
Since dust and dirt may enter between the shaft holes 6L, 6R and the shaft holes 6L, 6R, it becomes difficult for the shaft pins 5L, 5R to rotate as they collect, and the state conversion of the pair of movable blade pieces 2L, 2R cannot be performed smoothly. There was a problem.

Therefore, the object of the present invention is to provide a variable prize that can maintain a smooth state change without disturbing the movement of the movable wing piece even if an obstacle such as dust or dust enters the portion that rotatably supports the movable wing piece. To provide a device.

[Means for Solving the Problem] According to the present invention, by inserting one movable wing piece mounted on the game board surface of a ball game machine and an axial pin into an axial hole provided in each movable wing piece. In a variable winning device including a support member that rotatably supports a movable wing piece, a groove is provided on an inner peripheral surface of a shaft hole of the movable wing piece.

Alternatively, in the variable winning device including the pair of movable blades and the supporting member as described above, the groove is provided on the peripheral surface of the shaft pin projecting to the back surface side of the supporting member.

[Operation] According to the present invention, in the variable winning device having the groove on the inner peripheral surface of the shaft hole of the movable wing piece, if dust or dust enters between the shaft hole and the shaft pin of the movable wing piece, they will be pinned. It is collected in the groove of the shaft hole by the rotation of. Therefore, the rotation of the shaft pin is not hindered in the shaft hole, and the smooth rotation of the movable blade piece can be maintained.

The same applies to the variable winning device in which a groove is provided on the peripheral surface of the shaft pin protruding to the back side of the support member according to the present invention, and dust and dirt that has entered between the shaft hole and the shaft pin of the movable wing piece are Since it is collected in the groove of the shaft pin, the rotation of the shaft pin is not hindered and smooth rotation can be maintained.

It should be noted that the dust and dirt collected in the groove may be appropriately removed before it overflows from the groove, and the operation can be easily performed only by removing the supporting member and the movable blade piece.

[Embodiment] FIGS. 1 and 2 show an embodiment having the features of the present invention. In these figures, the same parts as those shown in FIG. 3 are designated by the same reference numerals.

First, in the embodiment shown in FIG. 1, a pair of movable blades 2L and 2R is used.
In the variable winning device including the mounting plate 3 mounted on the game board surface and the front cover 4 serving as a supporting member of the movable wing piece mounted on the front surface side, each movable wing piece 2
Grooves 7 are formed on the inner peripheral surfaces of the shaft holes 6L, 6R provided in L, 2R. At least one groove 7 may be provided, but each axial hole
It is preferable to form a plurality of pieces over the entire length of 6L, 6R (width of the movable blade). In the illustrated example, four grooves 7 are provided at equal intervals around the shaft holes 6L and 6R.

According to this embodiment, the pair of shaft pins 5L, 5R projecting rearward from the back surface of the front cover 4 are connected to the shaft holes 6 of the movable blade pieces 2L, 2R.
The movable blades 2L, 2R are rotatably attached by inserting them into L, 6R and fixing the front cover 4 to the mounting plate 3 with screws or the like. In this state, if dust or dirt enters the shaft holes 6L, 6R of each movable blade piece, they are collected in the groove 7 of the shaft hole by the rotation of the shaft pins 5L, 5R. Therefore, the shaft pins 5L and 5R can maintain smooth rotation in the shaft holes 6L and 6R despite the intrusion of dust and dirt.

Next, the embodiment shown in FIG.
In a variable winning device including 2L, 2R, a mounting plate 3, and a front cover 4, a groove 8 is provided on the peripheral surface of the shaft pins 5L, 5R protruding from the front cover 4. It suffices if at least one groove 8 is provided, but it is preferable to form a plurality of grooves 8 over the entire length of each shaft pin 5L, 5R. In the illustrated example, four grooves 8 are provided on the peripheral surfaces of the shaft pins 5L, 5R at equal intervals,
As a result, the cross sections of the shaft pins 5L and 5R are substantially cross-shaped.

According to this embodiment, the pair of shaft pins 5L and 5R are inserted into the shaft holes 6L and 6R of the respective movable blade pieces 2L and 2R, and the front cover 4 is attached to the mounting plate 3.
Even if dust or dirt enters the shaft holes 6L, 6R of each movable wing piece in the state of being mounted on the, they are collected in the grooves 8 of the shaft pins 5L, 5R. Therefore, similar to the embodiment of FIG. 1, the shaft pins 5L, 5R can maintain smooth rotation in the shaft holes 6L, 6R.

Each of the above-described embodiments can be easily disassembled as needed for parts replacement and the like. That is, it is only necessary to remove the screws or the like that fix the front cover 4 to the mounting plate 3. At that time, it is possible to remove dust and dirt accumulated in the grooves 7 or 8.

Although the embodiment has been described above, the present invention is not limited to this. For example, the mounting plate can be omitted. Further, the shaft hole provided in the movable wing piece and the shaft pin inserted therein may have any shape as long as at least one groove is provided. The shaft pin may project from the mounting plate instead of the front cover. In addition, the structure of the variable winning device of the present invention, the number of constituent parts, the shape, and the like can be arbitrarily set.

[Effects of the Invention] As described above, according to the present invention, even if dust or dirt enters the portion that rotatably supports the movable wing piece, they are collected in the groove provided in the shaft hole or the shaft pin. Therefore, the rotation of the shaft pin in the shaft hole is not hindered, and the smooth rotation of the movable wing piece can be maintained. Further, dust and dirt collected in the groove can be easily removed at an appropriate time.
