DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass frame mounting mechanism for a ball game machine.

[0002]

2. Description of the Related Art In a ball game machine represented by a pachinko machine or an arrangement ball type pachinko machine, the front side of a game board is covered with a transparent plate (usually a glass plate). As illustrated in FIG. 6, in a conventional ball game machine 90, an outer frame 91 holds a front frame 92, and a metal frame 93 fixed to the front frame 92 holds a glass frame 94.

The glass frame 94 is attached to the ball game machine 90 by integrating the metal frame 93 and the glass frame 94 in advance, and nailing the integrated one to the front frame 9.
It was based on the process of attaching to 2. This is a structure in which the metal frame 93 and the glass frame 94 are manufactured by press working, and the swing shaft of the glass frame 94 is held by a bearing provided on a part of the metal frame 93.
After attaching the glass frame 94 to the front frame 92,
Due to the failure to adopt the procedure for attaching to

[0004]

However, the metal frame 9
Since the glass frame 94 and the glass frame 94 are easily deformed, and the one obtained by integrating them is a relatively large part, it is not easy to accurately attach the glass frame 94 to the front frame 92 without distortion. Also, for example, in disposal of a ball-and-ball game machine, removing the metal frame 93 and the glass frame 94 from the front frame 92 has not been a simple operation.

An object of the present invention is to improve the work efficiency in the manufacturing process of a ball game machine by simplifying the attachment and detachment of the glass frame, and to facilitate the disassembly work for disposal.

[0006]

According to the first aspect of the present invention, there is provided a glass frame mounting mechanism for swinging around a swing shaft supported by a main body of a ball game machine. A glass frame mounting mechanism for mounting a glass frame covering the front side of the game board with a transparent plate held by itself when the glass frame is closed to the main body side when the main body side is closed. , An upper bearing having an upper bearing hole for holding an upper end of the oscillating shaft and fixed to an upper end of the supporting substrate, and a lower bearing hole for holding a lower end of the oscillating shaft An L-shaped member comprising a lower bearing provided with a mounting base for holding the lower bearing, wherein the mounting base is connected to the support substrate and is in a loosely connected state where the mounting base is not fixed. Close to the support substrate so that the lower bearing hole is And a closed position where the upper bearing bore coaxially,
A movable member that swings and displaces between an open position in which an upper end side of the mounting base is detached from the support substrate and a distance between a tip of the lower bearing and the upper bearing is larger than the closed position; And fixing means for fixing the movable member positioned to the support substrate.

Although the glass frame holds a transparent plate that covers the front side of the game board, it is somewhat inappropriate to call it a glass frame, but the material of the transparent plate (for example, whether it is glass or plastic) Regardless of the above, the frame that holds the frame is usually called a “glass frame”, and therefore, the present invention also calls it a glass frame.

The supporting substrate, the upper bearing and the movable member support the load of the glass frame including the transparent plate.
For example, it is preferable to use a metal such as a steel plate. However,
If the strength is sufficient, a material such as plastic may be used. The support substrate is fixed to the main body side of the ball game machine, and an upper bearing is fixed to an upper end of the support substrate. The support substrate is
For example, it is fixed to the main body side by bolts, nails, adhesives or the like, but bolting is excellent in consideration of workability during disassembly.

The upper bearing may be fixed to the support substrate by, for example, bolts or spot welding, but the upper end of a metal plate-like member that is formed in series with the support substrate is bent. When formed, it is simple and has good strength.
The upper bearing is provided with an upper bearing hole for holding the upper end of the swing shaft.

The movable member is an L-shaped member comprising a lower bearing and a mounting base, and may be an L-shaped metal piece, for example. The lower bearing is provided with a lower bearing hole for holding the lower end of the swing shaft. In the movable member, in a loosely connected state in which the mounting base is connected to the supporting substrate and is not fixed, the movable base moves the mounting base closer to the supporting substrate so that the lower bearing hole becomes coaxial with the upper bearing hole, and The upper end is separated from the support substrate, and swings between an open position where the distance between the tip of the lower bearing and the upper bearing is larger than the closed position.

Therefore, when the movable member is in the open position, the upper end of the swing shaft of the glass frame is inserted into the upper bearing hole of the upper bearing, and then the lower end of the swing shaft is inserted into the lower bearing hole of the lower bearing. The task of doing this is extremely easy. Then, the movable member is set to the closed position while the lower end of the swing shaft is inserted through the lower bearing hole, and the movable member is fixed to the support substrate by the fixing means, whereby the mounting of the glass frame is completed. Therefore, the work of attaching the glass frame is extremely simple. It can be removed very easily by working in the reverse order.

As the fixing means, a means having reversibility in fixing and releasing, such as a bolt or a pin, is preferable. The glass frame may have one swing shaft or may be vertically divided into two swing shafts. The upper and lower bearing holes may be through holes or blind tubes.

As a configuration for bringing the movable member into the loosely connected state, the configuration described in claim 2 is exemplified. That is,
3. The glass frame mounting mechanism according to claim 2, wherein the movable member is in the loosely connected state by engaging an engaging ear provided at a lower end of the mounting substrate with an engaging hole provided in the support substrate. In the loosely connected state, the swing displacement is performed with the vicinity of the engagement ear as a fulcrum.

With this configuration, the structures of the movable member and the support substrate are not complicated, and it is easy to loosely connect the movable member to the support substrate. The support substrate, the upper bearing, and the movable member are formed by bending an upper end portion of a metal plate-shaped member that is a series with the support substrate, wherein the upper bearing is formed as described in claim 3. If L-shaped metal pieces are used, their manufacture can be performed by, for example, press working, which is extremely simple and advantageous in cost.
