Description

[Detailed Description of the Invention] The present invention relates to an opening/closing safe hole in a pachinko machine, that is, an opening/closing safe hole called a tulip.

Conventional opening/closing safety holes are mechanically extremely complex, and as a result, they are time-consuming and costly to manufacture, and they often break down, especially if they break down during play, which can kill the interest in playing. There were some shortcomings.

Therefore, the present invention has been devised to overcome all of these drawbacks by extremely simplifying the configuration.

Hereinafter, the present invention will be described in more detail with reference to illustrated embodiments.

Fig. 1 is a perspective view of the blade in an open state, Fig. 2 is a front view, Fig. 3 is a sectional view taken along line A-A in Fig. 1, and Fig. 4 is an explanatory diagram of the mode of operation. It is.

In the figure, 1 is a board, and 2 and 2 are openable and closable wing pieces 4 that are pivotally attached to the lower part of the board 1 with a lower safe hole 3 drilled in the board 1 in between. .
In addition, each of the retractable wings 2, 2 has a triangular protrusion 5 which, when a ball falls and touches the outer surface 2a, causes the touched wing to rotate and open due to the weight of the ball. It is provided. 6 is a magnet fixed to the center of the lower edge of each of the wing pieces 2, 2;
2 is in an open state, this state is maintained by the mutual attraction of the magnets. For this reason, even if a ball accidentally rebounds from the lower surface of the wing and touches the wing while the wings are open, the wing will not close. Therefore, once the ball is opened, it remains open until the next ball enters, so there is no chance of the ball closing due to accidental contact with a bouncing ball, which would disappoint the player, as in the conventional case. Moreover, the wing pieces 2, 2 are
The distance 1 between the opposing lower edges is set to an appropriate distance so that the ball traveling on one side of the wing and falling does not touch the other side of the wing when passing between both wing pieces. This is the most important feature of the present invention. By doing this, both wing pieces will not be closed together by one ball, thereby increasing the interest of the game. Further, 7 is a ball holder protruding from the lower surface of the lower safe hole 3 of the substrate 1. Reference numeral 8 designates a ball receiving frame that protrudes in front of the upper safe hole 9 drilled in the upper part of the board 1, and has a notch 8 at the bottom leaving the center part 8a.
b, 8b, and when the blades 2, 2 are closed, the upper ends of the blades 2, 2 enter through the notches 8b, 8b and lean against the center portion 8a. The present invention can be attached to a pachinko machine by placing the board 1 at an appropriate position on the game board surface. Note that 10 in the figure indicates a sphere.

The mode of operation of the present invention having the above configuration will be explained below.

In FIG. 2, when the ball 10 falls into the ball receiving frame 8, the impact of the falling ball 10 forces the upper ends of both wing pieces 2, 2 apart to the left and right. Therefore, the wing pieces 2, 2 are rotated and opened to the position where the protrusion 5 contacts both ends of the ball receiver 7 of the lower safe hole 3, as shown in FIGS. 1 and 2. This state is reliably maintained until the next ball enters due to the mutual attraction between the magnets 6, 6, and even if the temporary ball accidentally touches the lower surface of the wing piece 2, it will not return and close. Furthermore, in addition to the above, even if a ball falls and touches the triangular protrusion 5 provided on the outer surface of the wing pieces 2, 2, the wing piece 2 that touched will open due to the weight of the ball. As a result, the player feels as if he has made a profit, which helps to increase his interest in the game (see Figure 4). When either or both of the wing pieces 2 are open and the next ball falls onto either wing piece, the lower edge of the wing piece on which the ball fell will be lowered by the weight of the ball. , and then rotates to return to its original state.

Also, if the next ball falls onto one of the wing pieces with both wing pieces 2, 2 open,
In the present invention, in particular, as mentioned above, the distance between the lower edges of the wing pieces 2, 2 is set such that the ball traveling on one side of the wing and falling does not touch the other side of the wing when it passes between the two wing pieces. Since the spacing is appropriate, only the wing on which the ball fell will stand up, while the wing on the other side will continue to jut out laterally.

Since the present invention has the above-described structure and operation, it is possible to provide a safe opening and closing hole that has a very simple mechanism, is easy to manufacture, can be manufactured at low cost, and has fewer failures. In addition, when both wing pieces are open at the same time and the next ball falls on either side, only the wing piece on which the ball fell will stand up, preventing both wing pieces from closing together. Since the structure is such that there is no problem, the player is given an opportunity to surely increase the number of prizes won, thereby doubling the interest of the game. Therefore, the present invention can enhance the enjoyment of pachinko games, and has many practical uses and benefits.
