Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a glass frame for a pachinko machine that is integrated with a guide rail for guiding pachinko balls launched from a launch guide rail to a game board. be.

[Prior Art] Conventionally, there have been known machines in which the game board is removable from the base frame so that the model of the pachinko machine can be changed by replacing only the game board. Also, according to Utility Model Publication No. 55-15882,
Normally, members such as guide rails that are fixed to the game board are integrated into a mechanical frame that is separate from the game board, and when replacing the pachinko machine, the mechanical frame is separated from the game board and only the game board is left alone. A pachinko machine has also been proposed in which the mechanism frame can be reused as is by replacing the mechanical frame. According to this, the structure of the game board to be replaced is further simplified, and the cost of the game board can be reduced.

However, as described above, if the guide rail is provided on the mechanism frame that is separated from the game board, the work of attaching the mechanism frame will be added when replacing the pachinko machine. Moreover, when performing the replacement work, the launch guide rail provided on the base frame,
In order to accurately align the mechanism frame with the guide rails provided on the mechanism frame, it is necessary to accurately attach the mechanism frame to the game board and then accurately fix the game board to the base frame. Therefore, in the past, there was a problem that replacing the game board was extremely troublesome and time consuming.

[Problem that the invention attempts to solve]

The present invention was devised to solve the problems of the conventional technology described above. By omitting at least a part of the guide rail from the game board, the cost of the game board can be reduced, and when the game board is replaced, the firing guide The purpose is to eliminate the work of accurately positioning the rail and the guide rail.

[Means for solving problems]

In order to achieve the above object, the present invention creates a glass frame by molding that can be attached to the base frame to which the game board is fixed in such a way that it can be opened and closed, and the glass frame has an opening that exposes the game board to the front side. In addition, there is a guide surface that surrounds this opening, on which a guide rail is attached to guide pachinko balls launched along the launch guide rail provided on the base frame to the playing surface of the game board, and a guide surface that surrounds this opening and the top edge of the glass frame. It is integrally molded with glass holding protrusions that hold the left and right sides of the front glass inserted from the side from the front and back.

Hereinafter, one embodiment of the present invention will be described with reference to the accompanying drawings.

〔Example〕

As shown in Fig. 1, a pachinko machine using the present invention has a base frame 1 which is attached via a hinge 2 to an island stand or a machine frame (not shown) fixedly installed in a pachinko parlor so that it can be opened and closed. , a game board 3 that is detachably fixed to the base frame 1 , and a glass frame 5 that is attached to the base frame 1 via an attachment shaft 4 so as to be openable and closable.

The base frame 1 is formed with an opening 6 for receiving the back mechanical part on the back side of the game board 3, a protrusion 7 for positioning the game board 3, an opening 8 for installation into which a fixing metal fitting for the game board 3 is inserted, and the like. It is manufactured as an integrally molded product. Further, the base frame 1 is formed with ejection ports 9 and 10 for prize balls, and a lower tray 11 for receiving the prize balls ejected from the ejection port 10 is provided at the lower part of the base frame 1. Further, an operating handle 12, a firing device 13, and a guide rail 14 are attached to the base frame 1, and when the operating handle 12 is operated, the firing device 1
3 is activated, and pachinko balls are launched toward the game surface 3a of the game board 3 along the guide rail 14. It should be noted that a rail 15 is attached to the gaming surface 3a in addition to well-known safe holes, tulips, winning ball devices, and the like.

The glass frame 5 is manufactured as an integrally molded product having an opening 16 for exposing the gaming surface 3a to the front side and protrusions 18a and 18b for holding the front glass 17. The protrusion 18a, 1
In consideration of the moldability of the glass frame 5, the projections 8b form a row of projections such that the projections 18a and 18b do not overlap when viewed from the front side, and are inserted from the upper edge of the glass frame 5. The front glass 17 is held between this row of protrusions.

As shown in FIG. 2, the surface on which the opening 16 is formed is located on the back side of the protrusions 18a and 18b, and when the glass frame 5 is closed, the back surface 19 is the gaming surface. 3a. A guide rail 20 made of a thin steel plate is fixed to the inner circumferential wall 16a forming the opening 16. In order to fix the guide rail 20 to the inner circumferential wall 16a, screws 22 for fixing the rubber piece 21 to a part of the inner circumferential wall 16a are used as shown in the figure, or an adhesive or the like is used.
Note that the rubber piece 21 is used as a member for bouncing back pachinko balls shot onto the gaming surface 3a.

The glass frame 5 has an outlet 9 provided in the base frame 1.
An opening 24 is formed through which the prize ball passes, and a gutter 25 is inserted and fixed into this opening 24. An upper plate 27 is fixed to a mounting portion 26 integrally formed on the front surface of the glass frame 5. The upper tray 27 functions to store prize balls and to feed the pachinko balls one by one into the firing device 13 via the inlet 28.

According to the above configuration, when the game board 3 is fixed to the base frame 1 and the glass frame 5 is closed, the back surface 1 of the glass frame 3
9 is brought into close contact with the game surface 3a of the game board 3, and the edge on the back side of the guide rail 20 is also brought into close contact with the game surface 3a. As shown in FIG. 2, the starting end 20a of the guide rail 20 is brought to a fixed position with respect to the upper end 14a of the firing guide rail 14 fixed to the base frame 1. Further, the lower end 15a of the rail 15 fixed to the gaming surface 3a is aligned with the terminal end 20b of the guide rail 20. Therefore, the launch device 13 launches the launch guide rail 1.
The pachinko balls launched along the line 4 are guided by the guide rail 20 and reach the game surface 3a. Pachinko balls that have won a prize such as a safe hole or a ticket reach the back mechanism part of the game board 3, and pachinko balls that have not won a prize are placed on a rail 15 fixed to the playing surface 3a or a guide fixed to the glass frame 5. It is sent to the back mechanism section along the rail 20 through an out hole 29 formed in the game board 3.

Since the glass frame 5 is attached to the base frame 1 to which the game board 3 is fixed, the glass frame 5
The relative position of the guide rail 20 of the base frame 1 and the guide rail 15 of the base frame 1 can be easily maintained constant. Furthermore, as in the illustrated embodiment, by attaching the upper plate 27 to the glass frame 5, the upper plate 27
This makes it possible to omit the front plate that was provided separately from the glass frame for attaching the glass frame, which is advantageous in terms of manufacturing and assembly.

[Effect of idea]

As mentioned above, in this invention, the guide surface for attaching the guide rail and the protrusion for holding the front glass are integrally molded on the glass frame, which is attached in a constant relationship with the base frame to which the game board is fixed, so that the guide surface By simply attaching the guide rail to the base frame, there is no need for troublesome alignment between the guide rail and the guide rail, and the front glass can be placed in a fixed position by simply dropping the front glass from above the glass frame. can be retained. Furthermore, since the glass frame is made into an integrally molded product, it is superior in strength to conventional glass frames using thin metal frames, and is also effective in preventing fraud. Furthermore, since an opening is formed in the glass frame to expose the game surface of the game board to the front, it is possible to omit the front plate that was conventionally placed over the front of the game board for the same purpose.
