DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support structure for a front frame of a ball and ball game machine.

[0002]

2. Description of the Related Art Conventionally, for example, in a pachinko game machine, a front frame is pivotally mounted on one side of the front of the machine frame so as to be openable and closable. Therefore,
For example, Japanese Patent Publication No. 4-5083
No. 8 discloses a technique disclosed in Japanese Patent Publication No. As shown in FIG. 7, first pivot members 111 are fixed to upper and lower portions of one side edge of the machine frame 110, and second pivot portions are fixed to upper and lower portions of one side edge of the front frame 112. Materials 113, 113 are fixed, and each of the first shaft support members 111, 111 and the second shaft support members 113, 1
13 protruding forward from the front frame 112 from each of
14, 114 are provided integrally.

A vertically extending shaft support tube 115 is provided on the shaft support plate 114 of the upper first shaft support member 111, and the projecting shaft 1 is provided on the upper surface of the shaft support plate 114 of the lower first shaft support member 111.
16 are provided. Also, the upper second support member 11
A shaft 117 is provided on the lower surface of the third shaft support plate 114, and a shaft hole 118 is formed in the shaft support plate 114 of the lower second shaft support member 113. Therefore, each of the upper shaft support plates 114, 114
And the lower shaft support plates 114, 114 are overlapped with each other, and a shaft 117 is inserted into the shaft support cylinder 115 from above, and
The front frame 112 is attached to the machine frame 110 by fitting a shaft hole 118 to the frame 16 from above.

On the other hand, recently, the front frame of a pachinko gaming machine can be easily formed and its commercial value can be increased. Various methods have been devised, such as attaching a plate or integrally molding a front frame itself with a synthetic resin so that the front surface has a novel design.

[0005]

However, in the conventional pachinko game machine, the support structure of the front frame 112, in particular, the upper and lower support plates 114, 114 are located forward of the front surface of the front frame 112. Since it protruded and was exposed to the outside, the design was uncomfortable and the commercial value was poor. For this reason, a design process for covering and covering each shaft support plate 114 is required.
2 is molded integrally with synthetic resin, the front frame 11
The other side of the front frame 112 can be freely swelled forward to make a desired design, but one side of the front frame 112, that is, the shaft support side, must have a flat design that cannot be swelled forward too much. This is because when pachinko gaming machines are installed in multiple rows on an island that is installed in a pachinko hall, a ball rental machine that can exchange coins for pachinko balls is interposed between each of the pachinko gaming machines. Since the front frame 112 is supported by one side edge of the machine frame 110, when the front frame 112 is opened, one side of the front frame 112 hits the ball lending machine to open and close the front frame 112. This is because there is a risk of causing trouble. Therefore, the front frame 11
It was impossible to make the front shape of No. 2 a symmetrical shape while maintaining the left-right balance, and the design was limited.

On the other hand, there is a structure in which a hinge is used as a supporting structure of the front frame 112, particularly a synthetic resin front frame. In this kind of supporting structure, the machine frame and the front frame are hinged by screwing. Therefore, in the manufacturing process, fine adjustment of the shaft support is required in order to properly maintain the positional relationship of the front frame 112 with respect to the machine frame 110, and complicated work is required.

Further, when the pachinko gaming machine is shipped from a manufacturer of the pachinko gaming machine, the pachinko gaming machine may be stacked upside down on a truck bed.
Since only the shaft 117 and the shaft hole 118 of the upper and lower second shaft support members are respectively fitted to the shaft support cylinder 115 and the protruding shaft 116 from above, the pachinko gaming machine is turned upside down. Then, the shaft 117 or the shaft hole 118 is likely to come off, and there is a danger that the front frame 112 may fall off.

Accordingly, the present invention has been made to solve the above-mentioned problem, and it is possible to achieve a well-balanced left and right design even with a resin-made front frame, and the front frame opening operation is not hindered at all. It is an object of the present invention to provide a front frame support structure for a ball game machine capable of efficiently producing a pachinko game machine without causing any fine adjustment of the shaft support portion.

[0009]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a ball game machine having a front frame openably and closably mounted on one side of the front of the machine frame. A first pivot member is fixed to each of the upper and lower parts, and a movable piece that pivotally supports one end and rotates in a horizontal plane with the other end as a free end is attached to each of the first pivot members. A second support member, which protrudes from the back side of the front frame and is supported by the free end of each movable piece, is fixed to one upper and lower part of the frame, and the movable pieces are always fixed to the machine frame by a spring means. Side, the movable piece rotates to allow the front frame to move to the other side of the machine frame by a predetermined amount when the front frame is opened, and
Each of the second pivot members has a configuration in which a horizontal piece protrudes into each of the first pivot members when the front frame is closed.

Therefore, when the front frame is opened, the movable piece rotates to move the front frame to the other side of the machine frame. As a result, the front frame is opened apart from the ball rental machine adjacent to the pachinko gaming machine, and even if the front frame is made resinous by providing a sufficient space, the second frame member side Of the front frame can be swelled forward without hitting the ball lending machine, and a symmetrical design of the front frame can be achieved. In addition, the second pivot member projects behind the front frame,
Since it does not protrude forward of the front surface together with the first pivot member, there is no unnatural feeling in design.

Further, by urging the movable piece so as to be constantly pulled to the other side of the machine frame by the resilient force, the movement of the second pivot member when the front frame is opened can be smoothly performed,
The opening operation of the front frame can be easily performed. Further, if a pawl plate interposed in the first pivot member is protruded from the second pivot member when the front frame is closed, when the pachinko gaming machine is shipped from the manufacturer, the pachinko gaming machine can be mounted on a truck bed. Even in the case of stacking upside down, it is possible to prevent an accident such that the respective second support members come off from both movable pieces and the front frame falls off.

As shown in FIG. 4, the lower first shaft support member 20 a and the second shaft support member 70 a are assembled by inserting the protruding shaft 45 a provided in the first shaft support member 45.

The supporting structure of the front frame of the pachinko gaming machine according to the present invention has the above-described structure. When the front frame 2 is closed with respect to the machine frame 1 as shown in FIG. One side edge of the horizontal piece 72 of the support member 70 has one shaft cylinder 30a.
And the movable piece 40 against the traction force of the coil spring 50.
Are arranged on one side of the machine casing 1. In this state, FIG.
As shown in (b), as the front frame 2 is opened, the arcuate surface 72a of the outer edge of the horizontal piece 72 is guided by the shaft cylinder 30a to make sliding contact, and at the same time, the movable piece 40 is moved by the traction force of the coil spring 50. 1, and the protruding shaft 75 of the second shaft support member 70 also moves to the other side of the machine frame 1.

Further, by opening the front frame 2, FIG.
As shown in (c), the horizontal piece 72 separates from the barrel 30a, the movable piece 40 comes into contact with the other barrel 30b, stops, and is held at that position. Thereby, the second shaft support member 70
6, that is, the front frame 2 moves a predetermined amount to the other side of the machine frame 1 from the position shown in FIG. Therefore, in a state where a plurality of pachinko game machines are arranged on the island stand of the pachinko hall with a ball rental machine (not shown) interposed therebetween, FIG.
As shown in (d), even if the front frame 2 is widely opened with respect to the machine frame 1, the front frame 2 is separated from the ball lending machine, so that there is sufficient space in the front frame 2, and the front side of the front frame 2 is supported by the pivot. An overhang can be provided to the front. In addition, the lower first
The shaft support member 20a and the second shaft support member 70a perform the same operation.

Although the coil spring 50 is not always necessary, the force which is always pulled by the movable piece 40 acts on the coil spring 50, so that when the front frame 2 is opened, the front frame 2 is easily and smoothly. The front frame 2 can be stably moved because the horizontal piece 72 moves and is guided while sliding on the shaft cylinder 30a. In addition, since each horizontal piece 72 intervenes in each of the first shaft support members 20 and 20a when the front frame 2 is closed, each of the horizontal pieces 72 may be stacked upside down such as when the pachinko game machine is shipped from a manufacturer. Horizontal piece 72,
72 is engaged with the first shaft support members 20 and 20a, and the front frame 2
Can be prevented from unnecessarily dropping out of the machine frame 1.

Although the present invention has been described with respect to a pachinko game machine, it is needless to say that the present invention can be applied to other ball game machines such as an arrangement ball machine.

[0028]

According to the ball game machine of the present invention, the front frame supporting structure of the front frame has the above-described structure, and thus has the following effects. When the front frame is opened, the front frame is separated from the ball rental machine, so that there is enough space for the front frame, so that a synthetic resin plate can be attached to the front of the front frame or the front frame itself can be integrated with synthetic resin. Also in the case of molding, it is possible to freely design in a symmetrical shape by bulging out the front surface of the front frame while maintaining the left-right balance. In addition, since the upper and lower first and second pivot members are all disposed on the back side of the front frame and do not protrude forward, the design area of the resin extends to the pivot portion side of the front frame, which is combined with the above-mentioned effects. The design can be innovative and the product value can be increased. Since the shaft support structure is not completely integrated like a conventional hinge, fine adjustment in the manufacturing process is not required, and complicated labor is eliminated. Since the horizontal pieces of the second pivot members are locked in the first pivot members when the front frame is closed, the pachinko gaming machines are stacked upside down when shipped from a pachinko gaming machine manufacturer. However, there is no danger that the front frame will fall off.
