Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a glass frame for holding the front glass of a pachinko machine, and more specifically, a glass frame for guiding pachinko balls launched from a launch guide rail to a game board. This relates to a glass frame that also has an integrally molded rail.

[Conventional technology]

2. Description of the Related Art Pachinko machines have been known in which a game board provided with winning ball receptacles, obstacle nails, etc. can be attached to and removed from a front frame. With such a pachinko machine, the model of the pachinko machine can be changed simply by replacing the game board, which is very rational. Furthermore, in the pachinko machine disclosed in Japanese Utility Model Publication No. 158825/1982, members such as rails that are normally attached to the game board are integrally molded into a mechanism frame that is constructed separately from the game board. When replacing a pachinko machine, the mechanism frame is separated from the game board and only the game board is replaced, and the mechanism frame can be reused as is. Therefore, the structure of the replaced game board is further simplified, which is advantageous in terms of cost.

However, as described above, if a rail is provided on the mechanism frame that is separated from the game board, when installing or replacing a pachinko machine, the work of installing the mechanism frame will be added to the conventional replacement work. Moreover, when attaching the mechanism frame to the game board, the mechanism is installed so that the firing guide rail provided at the bottom of the front frame to which the game board is attached and the rail of the mechanism frame can be maintained in the correct positional relationship. Accurate positioning work is required when attaching the frame, which complicates the work of attaching and replacing the pachinko machine and also complicates the structure for positioning.

[Problem that the invention seeks to solve]

The present invention was made in order to eliminate the drawbacks of the above-mentioned conventional technology, and when replacing a pachinko machine, it is possible to replace only the game board that is not provided with a rail, and to The purpose of the present invention is to eliminate the need for accurate positioning work between a separately provided rail and a launch guide rail provided on the front frame.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a glass frame which is provided in a front frame on which a game board is attached so as to be openable and closable, and whose positional relationship with the front frame is maintained constant. The rail connected to the guide rail is integrally molded.

According to a preferred embodiment of the present invention, the rail made of a thin metal plate is integrated into a glass frame made of synthetic resin by embedding molding.

〔Example〕

In FIG. 1 illustrating an embodiment of the present invention,
The front frame 2 fixed to the machine frame 1 has a prize slot, obstacle nails, windmills (all not shown), etc. on the front side 3.
A game board 3 provided at a is fixed by known means. A firing device (not shown) including a firing handle 4 that is operated when firing a pachinko ball is built into the lower part of the front frame 2, and the fired pachinko ball is ejected from a firing guide rail 5.

A glass frame 7 molded from synthetic resin is pivotally attached to the front frame 2 so as to be openable and closable. A slit 9 for inserting the front glass 8 is formed at the upper edge of the glass frame 7, and the front glass 8 inserted through the slit 9 is formed integrally with the inner side wall of the glass frame 7. It is held by the holding section 10 that has been moved.
In detail, as shown in FIG. 2, this holding part 10 consists of protrusions 10a and 10b that protrude intermittently, taking into consideration the suitability for molding the glass frame 7. Then, as shown in FIG. 3, the front glass 8 is held between the protrusions 10a and 10b.

A rail 12 made of a thin steel plate is embedded in the glass frame 7. In order to reliably embed and hold the rail 12 in the glass frame 7, for example, as shown in FIG.
What is necessary is to form a wedge-shaped band-shaped protrusion 12a on the back side of the 2. In addition, as shown in FIG. 4 or FIG. 5, the rail 12 and the glass frame 7 can be integrated by using a support piece 12b bent on the back side of the rail 12, a cut-and-raised part 12c, etc. You can also do that.

The portion surrounded by the rail 12 is a glass frame 7
Since the opening 13 penetrates from the front side to the rear side, even when the glass frame 7 is closed, this opening 13
and the front surface 3 of the game board 3 through the front glass 8.
a becomes observable. Note that the reference numeral 14 indicates a prize ball outlet 1 formed as an opening in the glass frame 7.
The opening 16 is an inlet for introducing the pachinko balls into the firing device.

After assembling the pachinko machine configured as described above, when the glass frame 7 is closed, the lower edge of the rail 12 comes into close contact with the front surface 3a of the game board 3, and the starting point 18 of the rail 12 is brought into contact with the launch guide rail 5. Ru. Therefore, the pachinko balls ejected from the ejection guide rail 5 by the ejecting device are guided by the rail 12 and guided onto the front surface 3a of the game board 3.
Since the glass frame 7 is attached to the front frame 2 to which the game board 3 is fixed, the communication between the rail 12 and the launch guide rail 5 is kept constant regardless of the accuracy with which the game board 3 is attached. Be able to do things.

In the above-mentioned embodiment, in order to insert a protective glass plate in addition to the front glass 8 into the glass frame 7, two slits 9 are provided, and another row of protrusions is added in addition to the protrusions 10a and 10b. You may. In this case as well, considering the molding suitability of the glass frame 7, the respective protrusion rows are formed intermittently in an alternating manner so as not to overlap in the cutting direction of the mold.

〔Effect of the invention〕

As described above, according to the present invention, the glass frame that can be opened and closed with respect to the front frame to which the game board is fixed is manufactured as an integral molded product, and Since the guide rails to be communicated are integrated with the glass frame, the communication between the two rails always maintains a constant relationship. Therefore, when replacing the game board, there is no need for precise positioning work, and only the game board needs to be replaced.
It is economical and at the same time improves work efficiency. In addition, the glass frame of the present invention, which is made of a molded product, has the following characteristics:
It is also extremely strong, making it effective in preventing fraud.
