Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a windmill for obstacles provided on the game board of a pachinko machine.

[Prior Art] Many obstacle nails are installed on the game board of a pachinko machine in order to guide the ball hit from the firing device to the winning hole, or to cause the ball headed for the winning hole to be missed.
For the same purpose, windmills are installed to change the direction of the ball's fall.

As is known, a windmill is a windmill equipped with multiple blades that is freely rotatable around a spindle, and is generally attached by nail-shaped spindles that are driven directly onto the surface of the game board.
Alternatively, a metal support shaft is inserted into a plastic mounting board so that it stands upright, and is attached to the game board via the mounting board.

This windmill rotates when the batted ball is received by the windmill body, and by this rotation, it distributes the batted ball left and right and changes its falling path, and it also changes the trajectory by colliding with the batted ball and bouncing it back, similar to the obstacle nail, As in the case of the obstacle nail, in the case of this windmill, the direction of the windmill body, that is, the direction of the spindle that stands up from the game board surface, has a subtle influence on the course of the ball. For windmills that do this, it has a great impact on the winning rate.

Therefore, conventionally, when adjusting the winning rate of a pachinko machine, the head of the spindle of the windmill is pressed to forcefully bend and deform it in the same way as an obstacle nail, and the direction of rotation of the windmill body is changed.

[Problem that the invention aims to solve] In order to adjust the falling direction of the ball, conventionally the spindle of the windmill was forced to bend and the spindle was bent to change the direction of rotation to distribute the ball, or to bias the direction of repulsion. However, if this forced bending operation is repeated, the straight support shaft will become deformed.
This interfered with the smooth rotation of the wind turbine body, causing the rotary sorting function to be lost, and the appearance to become unusable.

The present invention was devised in view of the above-mentioned circumstances, and its purpose is to enable adjustment of the falling direction of the batted ball by changing the direction of the spindle as necessary, and to make it possible to adjust the direction of fall of the ball. To provide an improved wind turbine in which the direction of the shaft can be easily changed and the straightness of the support shaft is not impaired even when the changing operation is repeated.

[Means for solving the problem] The present invention was made based on the above-mentioned purpose, and
The feature is that the support shaft that supports the wind turbine body in the front half of the shaft is inserted into the bearing hole provided in the mounting board, and the shaft is supported swingably using the bearing hole as the fulcrum. A receiving part is provided in the rear half of the shaft, and a spring is compressed between the receiving part and the edge of the bearing hole to constantly bias the support shaft backward, while a bearing plate is provided facing the rear of the mounting board. A windmill for a pachinko machine is provided, and the shaft end of the support shaft biased by the spring is brought into contact with the front surface of the bearing plate to support it.

[Function] The windmill of the present invention having the above configuration is fixed to the game board via the mounting board, and the windmill body supported on the front half of the spindle is projected to the front. The shaft end of the support shaft is usually pressed and supported by the front surface of the bearing plate using a spring installed between the support part of the support shaft and the edge of the bearing hole, and the shaft end is supported by the bearing hole of the mounting board. This will hold the support shaft horizontally and keep the rotating body in a rotatable state. The support shaft, which is biased backward by the spring, can be pulled forward along with the wind turbine body, and the shaft end that contacts the bearing plate can be released.
In addition, since this support shaft is inserted through the bearing hole so that it can swing freely, the direction of the support shaft can be changed by swinging this bearing hole as a fulcrum and moving the abutment point of the shaft end. can.

After this movement of the contact point of the shaft end, when the support shaft is released, the support shaft is again pushed backward by the force of the spring, and the shaft end contacts the bearing plate, and is supported in that position. The spindle is maintained in the changed orientation and supports the wind turbine body in a freely rotatable state.

Next, an embodiment illustrating a wind turbine according to the present invention will be described in detail, and its characteristics will be clarified.

[Example] Fig. 1 is a front view of a wind turbine according to the present invention, and Fig. 2 is a right side view with a part of the wind turbine shown in longitudinal cross-section at the center. In the drawings, 1 is a mounting board fixed to the game board, 2 is a spindle, and 3 is a windmill body rotatably supported on the spindle.

The mounting board 1 here is a circular plate, and a bearing hole 4 into which a support shaft 2 is mounted is provided in the center thereof.

The bearing hole 4 is opened in a thickened part of the mounting board, and is provided as a through-hole having a diameter slightly larger than the shaft diameter of the support shaft 2.

The support shaft 2 penetrates into the bearing hole 4 from the front side,
A shaft front half portion 2a protrudes from the front of the mounting board 1, and a wind turbine body 3 is rotatably supported thereon, and a spring 5 is wound around the shaft rear half portion 2b penetrating rearward.

The spring 5 has one end received by a collar-shaped receiving portion 6 provided near the shaft end of the shaft rear half portion 2b, and the other end received by the edge of the bearing hole 4, and is contracted between the two.
This spring force urges the support shaft 2 rearward. Due to this bias, the shaft end is pressed into contact with a bearing plate 7 provided at the rear of the mounting board.

The bearing plate 7 is supported so as to face each other by an arm 8 (in this case, a cylindrical body) extending from the back surface of the mounting board 1, and has a recess 9a corresponding to the bearing hole 4 in the front part thereof. A large number of shaft end receiving recesses 9 are provided around the center, and the shaft end of the support shaft 2, which is biased by the spring 5, is received and supported in one of the recesses.

The wind turbine body 3 has a cylindrical bearing part 3b hanging from the center of a circular base plate 3a, and three blades 3c extending radially from the circumferential surface of the bearing part at equal intervals. 3b is slidably fitted to the front half portion 2a of the support shaft so as to be supported.

In addition, in the figure, 10 is a stopper provided at the front end of the spindle to prevent the wind turbine body from coming off, and 11 is a stopper provided on the mounting board 1.
This is a screw hole for fixing the game board to the game board.

The windmill of the present invention is constructed as described above,
The bearing plate 7 is inserted from the front so as to fit into the mounting hole opened in the game board, the mounting board 1 is placed on the front side of the game board, and the fixing screw is passed through the screw hole 11 to fix it.

Since the repulsive force of the spring 5 is always acting on this windmill, the support 2 inserted into the bearing hole 4 is supported by the bearing hole 4 in the middle of its length, and its rear shaft end is pressed against the bearing plate 7. and a recess 9a provided therein.
The first half portion 2a of the shaft protruding forward from the mounting board is thereby held in a vertical or substantially vertical state, and the wind turbine body 3 can be supported freely in rotation.

In this way, the support shaft 2 inserted into the bearing hole 4 can be stably supported by the biasing force of the spring 5, while the shaft end can be fitted by pulling the support shaft forward. It can be removed from the matching recess 9a or recess 9, replaced with another recess, and then fitted and supported in the replaced recess again with spring force, so it can be freely supported against the mounting board 1 using the bearing hole 4 as a fulcrum. The rising angle of the shaft 2 can be changed.

4 and 5 show other embodiments of the shaft end receiving recess 9 formed on the front surface of the bearing plate 7 for receiving the shaft end of the support shaft 2. The one shown in FIG. FIG. 5 shows a case in which a large number of recesses 9 are formed in a grid pattern over the entire area of the mounting board 1, and FIG. This is a case where a large number of recesses 9 are arranged.

In all of these embodiments, a concave portion is carved into the bearing plate 7 itself, but it is also possible to attach a sheet-like material such as cloth, a net, or a foamed resin film to the front surface of the outer bearing plate. The shaft end of the support shaft may be held using the frictional properties of the texture, stitches, or film.

Figure 6 shows a spherical expanded diameter part 1 in the middle of the length of the support shaft 2.
2 is provided, and is slidably fitted to the hemispherical cavity-shaped receiving portion 13 provided on the front side of the bearing hole 4, so that the direction of the support shaft 2 can be changed smoothly without rattling between it and the bearing hole 4. In this embodiment, the mounting board 1 is made of a transparent plate, and a rotating wind turbine body 3 is illuminated by a lamp 14 provided behind the mounting board 1.

In the drawings, reference numeral 15 is a game board, 16 is a set plate provided with a safe ball passage etc. provided on the back of this game board, 17 is a post raised from this set board, and 18 is a fixed board via this post. This is a board for mounting the lamp 14.

In this embodiment, a cylindrical protection tube 19 is extended from the set plate 16 so as to surround the support column 17 and the mounting board 18, and a locking hook 20 is extended from the back side of the wind turbine mounting board 1. By hooking the claw of this hook into the locking hole 21 provided in the protection tube 19, the set plate 16 and the mounting board 1 are connected.
are integrated so that the lamp 14 faces behind the mounting board.

In addition, since the lamp mounting board 18 can be mounted on the pillar 17 of the set plate 16, the mounting board 1 with the wind turbine body 3 can be made separate, and therefore the lamp cord (not shown) The mounting board 1 can be inserted and removed without pulling out the lamp 14, and the lamp 14 can be replaced with the mounting board 1 removed. Further, since the attached lamp 14 is surrounded and protected by the protective tube 19, it will not be damaged during assembly work or the like.

The wind turbine of the present invention is constructed as described above, and during normal use, the spindle 2 supports the wind turbine body 3.
The rear shaft end contacts the bearing plate 7 under the bias of the spring 5, and is supported at this contact point, and also supported in the bearing hole 4 in the middle of its length, so that the mounting board 1
The wind turbine body can be supported in a fixed standing position and rotated freely against the wind turbine, and it performs the same function as a conventional wind turbine. However, when the support shaft 2 is pulled forward against the spring 5, the shaft end can be separated from the bearing plate 7 to release its support, and since the support shaft can be swung about the bearing hole 4 as a fulcrum, the direction of the support shaft 2 can be freely changed. Then, when the drawer is released, the changed support shaft can be pressed against the moved position by the bias of the spring 5 and supported again, so that the changed state can be maintained, and the orientation of this support shaft can be maintained. can be freely and repeatedly changed.

[Effects of the invention] Since the present invention is constructed and used as described above, there is no need to forcibly bend the spindle as in conventional wind turbines, and there is no need to forcibly bend the spindle, which may impair the rotation of the wind turbine body.
Or, you can always expect smooth rotation without damage.

In the wind turbine of the present invention, if you pull out the spindle along with the wind turbine body and change the orientation as desired, and then release the pull-out, the wind turbine body will be supported in the changed orientation, making it extremely easy to change the orientation of the wind turbine body. In addition, even if the direction is repeatedly changed, the spindle is not affected at all, so the rotation of the wind turbine body is not adversely affected.

In addition, the end of the spindle touches the bearing plate when the drawer is released, and since the spindle is supported at this contact point, it can be changed to any direction, making it extremely useful for guiding the falling direction of the ball. It's advantageous.
