Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a front frame of a pachinko machine integrally molded of plastic.

[0002]

2. Description of the Related Art A conventional pachinko machine uses a wood such as plywood to make a front frame, and on the surface of the front frame, a decorating plate is adhered or a plastic keyhole ornament is attached to enhance the decorative property. Fix with a game board storage frame made of iron plate on the back side of the front frame with a screw, attach a plastic frame board part to the lower part of the frame, and place the game board on the upper surface of the frame board part A game board is attached. Then, metal fittings for attaching to the machine frame are attached to one side above and below the front frame, and a hinge portion for attaching the glass frame and the opening / closing panel is also attached separately.

[0003]

However, if the front frame is made of wood, it becomes heavy in order to obtain the required rigidity, and the front part of the front frame must be flat, so that the front part is curved. It was difficult to improve the decorativeness by changing the setting. Further, since the game board storage frame, the frame board portion, various hinged portions, etc. must be separately attached, many steps are required just to assemble them with the front frame. Therefore, there is a demand for the development of a front frame which can be easily enhanced in decorativeness and is easy to assemble and has high rigidity.

[0004]

SUMMARY OF THE INVENTION Therefore, the present invention has been proposed in view of the above, and has an upper horizontal front surface portion, a lower horizontal front surface portion, a right vertical front surface portion, and a left side which are arranged in a rectangular shape on the same plane. Each front part of the vertical front part, a shallow box-shaped game board storage frame projecting rearward from the opening edge of the window portion surrounded by these, and a lower part of the game board storage frame, one of the game board storage frame The frame board part protruding forward from the rear part of the opening, protruding from the rear part, the game board mounting part on the upper surface, the firing rail mounting part formed on the front surface, and the hinge part that is hinged to the machine frame are integrally molded with plastic. Is a front frame of a pachinko machine characterized by.

[0005]

[Function] Since the game board storage frame and frame board projecting rearward from the front and window portions arranged in a square shape are integrally molded with plastic, compared to the case where the game board storage frame or frame board is attached afterwards. Demonstrate high rigidity.

The projecting walls 54, which form the main part of the foul ball recovery gutter, are formed by integral molding, and the flat portion on the right side of the projecting wall 5 serves as the launch rail mounting part 33. As shown in FIG. 5, the inside of the frame board portion 34 includes reinforcing ribs 55 ...
With a hollow structure reinforced by, the weight is reduced while ensuring the required strength.

[0018]

As described above, according to the present invention, the front portions of the upper horizontal front surface portion, the lower horizontal front surface portion, the right vertical front surface portion, and the left vertical front surface portion, which are arranged in a square shape, and the window portion. Shallow box-shaped game board storage frame protruding rearward from the opening edge of the game board, frame board part formed in the lower part of the game board storage frame, and hinged part that is hinged to the machine frame are integrally molded from plastic Therefore, it is possible to provide a front frame of a pachinko machine that is lightweight but has sufficient rigidity. Moreover, the decorative property can be enhanced by integrally molding the synthetic resin without separately mounting the decorative component, and it is not necessary to separately mount the game board storage frame or the frame board. Therefore, the work of assembling the pachinko machine can be simplified. Furthermore, the amount of wood used can be reduced, and plastics can be recycled, which can contribute to the protection of natural resources. Furthermore, by forming the hinged parts such as the hinged part that is hinged on the machine frame, the hinged part for the glass frame, and the hinged part for the opening / closing panel by integrally molding with the front frame, the hinged part can be attached later. In comparison, not only the work of attaching the hinged portions themselves is unnecessary but also the work of adjusting the positions of the hinged portions is not necessary, so that the assembling work can be simplified.
