Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a ball launching rail device for a pachinko machine.

[Prior Art] A pachinko machine is provided with a guide path for returning balls to guide the balls that return toward the firing rail without reaching the upper part of the game board to a receiving tray.

Conventionally, the above-mentioned return ball guide path is constituted by a firing rail having a guide piece whose tip is bent downward toward the return ball guide path, and the firing rail is assembled to a mounting base. They were attached to form a ball launching rail device as a whole.

As a ball launch rail device in which a launch rail having this guide piece is assembled to a mounting base, for example, a launch rail device as shown in Figs. 4 and 5 of Publication No. 1987-62 is used. One side end of the rail 5a is assembled so as to be received by the upper end of the mounting plate 52a (corresponding to a mounting base), and the launch rail 5a
Folding piece 15 at the front end (corresponding to the guide piece) and mounting plate 2
It is known that the front end of 5a is in close contact with the front end.

[Problems to be solved by the invention] In the above-described conventional firing rail device, the folding piece 15 of the firing rail 5a is assembled in close contact with the front end of the mounting plate 25a, so that the impact of the returning pachinko ball cannot be absorbed. The firing rail 5a receives the damage properly and wears out the firing rail 5a at an early stage, which necessitates complicated replacement of the firing rail.

The present invention was developed in light of these circumstances, and its purpose is to create a pachinko machine that can be used for a long period of time by alleviating the impact of returning balls and suppressing wear on the firing rail. A ball launching rail device is provided.

[Means for solving the problem] That is, the ball launching rail device according to the present invention has the following features:
"Equipped with a firing rail having a guide piece whose tip part is bent downward toward the guide path of the return ball, and a mounting base on which the firing rail is assembled so as to receive one side end of the firing rail at its upper end. This ball launching rail device for a Pachinko machine is characterized in that a gap is provided between the guide piece of the launching rail and the front end of the mounting base.

[Function] In the ball launch rail device according to the present invention, since the launch rail is assembled to the mounting base with a gap provided between the guide piece of the launch rail device and the front end of the mounting base, The impact of the returning pachinko balls received by the guide piece is absorbed and alleviated by the gap. Therefore, wear on the guide piece of the launch rail is reduced, allowing long-term use. In particular, the present invention adopts a configuration in which the firing rail and mounting base, which are the main components of the conventional ball firing rail device, prevent wear on the firing rail, and a new wear-preventing member is added. A structure is provided which prevents wear of the firing rail at a very simple and low cost without adding anything.

[Example] The present invention will be described below according to an example shown in the drawings.

As shown in FIG. 1, the ball launch rail device 1 is composed of a launch rail 10 and a mounting base 20, and is installed at the front right position of the lower game board surface 30a of the game board 30, which is divided into an upper part and a lower part. It's getting old. Note that 60 is a guide path for the returning ball.

From FIG. 2 to FIG. 7, the ball launch rail device 1
An embodiment of the launch rail 10 is shown in the figure.
The base end is formed to stand upwards, and has an opening 15 in which a hammer for hitting pachinko balls is exposed in this raised part, and a guide groove in the center of the upper surface that guides the pachinko balls to the upper part of the game board surface 30a. 12, and its tip is bent downward at an acute angle to form a guide piece 16 for the return ball of the pachinko ball. Furthermore, tongue pieces 14 are formed at appropriate positions on the sides of the launch rail 10 and are provided with screw insertion holes 13 for assembling the launch rail 10 to the mounting base 20 with screws 40.

The mounting base 20 is formed with a cylindrical body 23 having a screw hole 22 for assembling the launch rail 10 to the mounting base 20 with a screw 40, and has a ball stopper 2 at the upper right corner.
1 can be attached with screws 41. Further, on the outer peripheral surface of the mounting base 20, there are mounting holes 2 for attaching the mounting base 20 to the game board surface 30a.
4, and two pins 25 are provided protruding from the game board surface 30a side, as shown in FIG. A pin insertion hole 31 is provided in the game board surface 30a corresponding to the pin 25.

Now, regarding the ball launch rail device 1, as shown in FIGS. 3, 4, and 7, there is a space between the guide piece 16 at the tip of the launch rail 10 and the front end 20b of the mounting base 20. A gap 26 is provided.

The guide piece 16 is where the returning pachinko ball hits directly, and by providing the gap 26 as described above, the impact of the returning pachinko ball that is received by the guide piece 16 is absorbed and alleviated. It is becoming more and more like this. With this, the launch rail 10
wear is suppressed, and the ball firing rail device 1 can be used for a long time.

Further, in this ball launch rail device 1, as shown in FIG. 5, one side end 10a of the launch rail device 10 is
so that it is received by the upper end 20a of the mounting base 20,
A launch rail 10 is assembled to a mounting base 20. As a result, the firing rail 10 is structurally reinforced, especially against the force applied downward, and deformation of the firing rail 10 due to the impact of the returning ball is prevented, so that the entire ball firing rail device 1 has strength. It has a unique structure. However, such an assembly structure is a desirable assembly structure in a conventional ball launch rail device composed of a launch rail and a mounting base.

As shown in FIG. The pin 25 of the mounting base 20 is inserted into the pin insertion hole 31 of the game board surface 30a and positioned. Thereafter, the mounting base 20 is attached to the game board surface 30a by screws 42 or nails inserted into the mounting holes 24 formed on the outer peripheral surface of the mounting base 20.

Note that the gap 26 in this invention is not only provided near the base 16a of the guide piece 16 on which the firing rail 10 is bent, as in the above embodiment, but also partially provided near the base 16a of the guide piece 16. It may be provided over the upper end of the mounting base 20.
Further, the gap 26 is small enough to sufficiently alleviate the impact of the returning ball.

[Effect of the invention] As described above, in the ball launch rail device according to the present invention, a gap is provided between the guide piece of the launch rail device and the front end of the mounting base, so that the launch rail can be assembled to the mounting base. As a result, the impact of the returning pachinko balls received by the guide piece is absorbed and alleviated by the gap. For this reason,
Wear on the guide piece of the launch rail is reduced, allowing for long-term use. In particular, the present invention adopts a configuration in which the firing rail and mounting base, which are the main components of the conventional ball firing rail device, prevent wear on the firing rail, and a new wear-preventing member is added. Rather than adding anything, the present invention provides an extremely simple and inexpensive structure for preventing wear on the firing rail.
