Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a winning device for a pachinko machine.

Conventionally, one type of winning device has a support in which a pair of wing pieces are pivoted to freely open and close on the left and right sides of the opening of an entry pocket provided on the front surface of the base, and a swinging plate is installed horizontally on a frame provided on the back surface of the other base. Freely swinging bearing via the shaft,
The tip of this oscillating plate faces into the entry pocket through the entry opening provided on the mounting plate of the base body, and the tip of this oscillating plate is usually inserted between the wing pieces to ensure that the left and right wing pieces are separated. When the ball is held in an upright closed position and the ball enters between the winglets in this closed position,
This incoming ball converts the rocking plate into a backward tilted position, causing the tip part interposed between the wing pieces to jump up, thereby releasing the upright state of the wing pieces and opening them outward for the next hit ball. There is a known winning device in which the entry conditions are relaxed, and when the next ball enters in this state, the tip of the rocking plate intervenes between the wing pieces again to return to the closed position. There is. The present invention relates to an improved prize-winning device that is equipped with the pair of wing pieces and is opened and closed in response to the entry of a ball into the wing pieces, thereby changing the entry conditions.

In the conventional winning device of this type, a pair of wing pieces and a rocking plate are placed in an engagement relationship so that they move directly, and when the rocking plate swings due to an incoming ball, its tip causes the wing piece to jump. The ball was kicked in the upward direction to open the ball to the left and right, and then when the ball flew in, the tips of the rocking plates that had jumped up as the wings closed were pushed back down.
The relationship between the wing pieces and the rocking plate is a flexible engagement relationship, so that the other can be interlocked only during operation, but as mentioned above, the initiative is when the wing pieces are closed and opened. As a result, the wing pieces and the rocking plate took charge alternately.

For this reason, especially when the winglets are in an open state, normally the winglets are bent to close only when the ball is received by the winglet and enters the entry pocket, but when the winglet is open, If a ball collided with the outer surface and received an inward impact, the impact would be transmitted to the rocking plate and cause it to close, even though there was no incoming ball.

The present invention was developed in order to avoid such malfunctions of the blades that are not caused by the entry of a batted ball, and its purpose is to rotate the bridge member coaxially with the support shaft that supports the blades. This bridge member is interposed between the wing piece and the rocking plate, and when the tip of the rocking plate intervenes between the bridge members, the wing piece is restrained in a closed position, and the rocking plate moves in. When the tip part jumps up and releases the restraint of the bridge member due to the ball, the bridge member is rotated at the same time as the wing pieces are released to narrow the space between the two bridge members, and the bridge member and Basically, a magnet and an iron piece that attract each other are provided, and when the space between the two pieces of the bridge is narrowed, the pieces are attracted and the rotation of the piece is restrained. The malfunction is effectively prevented by preventing the tip of the plate from descending, and during this time, that is, while the blade is in the open position, even if the blade arbitrarily rotates in the closing direction, the blade does not change to the closing position. An object of the present invention is to provide a prize-winning device that avoids this problem.

Hereinafter, embodiments illustrating the present invention will be described. FIG. 1 is a front view of the device of the present invention in the closed position with a part of the right half cut out, and FIG. 2 is a central longitudinal view in the closed position. A right side view, FIG. 3 is a front view in the open position with a part of the right half cut out, FIG. 4 is a right side view taken along the center of the above figure, and FIG. 5 is a plan view.

1 is the base of the device of the present invention, 2 is a mounting plate for fixing this base to the front of the game board, 3 is a fly-in pocket provided on the front of the mounting plate 2, and 4 is a frame provided on the back. .

In the base shown here, a mounting plate 2 and a frame portion 4 are previously formed integrally, and a fly-in pocket 3 is formed separately and assembled to the front surface of the mounting plate.

The entry pocket 3 faces from the front so as to cover the entry port 5 that is vertically opened in the center of the mounting plate 2, and is fixed to the front surface of the mounting plate with screws, etc., and by this fixing, the upper part is It is designed so that an open pocket can be formed. And this pocket 3
A pair of support shafts 7, 7 are installed toward the rear from the front plate 6 along the upper right and left opening edges, and the wing pieces 8, 8 are rotatably supported on both support shafts. It is set as.

The wing pieces 8, 8 are formed symmetrically so that the center of gravity is unevenly distributed on the outside with respect to the respective support shafts 7, 7, and furthermore, here, weights 9, 9 are attached so that both wing pieces are always kept on the outside. It is designed so that if the robot falls on its side, it automatically assumes an open position.

Reference numerals 10 and 10 designate bridge members that are coaxially supported on support shafts 7, 7 that support the wing pieces 8, 8, and are rotatably assembled.

In this embodiment, the bridge member is arranged to fit into a notch 8' which is formed by cutting out a part of the bearing part of the blade 8, as shown in FIGS. 6-9. Two protruding pieces 12 and 13 are provided on the circumferential surface at an angle of approximately 90 degrees in the radial direction centering on the bearing hole 11 that receives the support shaft 7, and an impact provided on one of the protruding pieces 13 is provided. The joint portion 14 is brought into contact with the abutment portion 15 provided on the wing piece 8 so as to interlock with this wing piece.
Further, an adsorbing iron piece 16 is provided on one side of the projecting piece 13, and by adhering this iron piece to a magnet 17 provided at the opening edge of the fly-in pocket, free rotation about the support shaft 7 is restrained. It is designed so that it will be done.

As described above, this bridge member 10 is in an interlocking relationship by abutting the abutting part 14 with the abutting part 15 of the wing piece 8, so when it is in this state, the center of gravity is unevenly distributed. The protruding piece 13 is rotated inwardly by the wing piece 8 which is tilted toward the open position and takes an open position.
is brought into contact with the magnet 17, and an adsorbing iron piece 1 is provided on the magnet 17.
6 is attracted and its rotation is restrained, and the other protruding pieces 12 are respectively protruded in the opposite direction to narrow the space between the two bridge members.

FIG. 7 shows that by opening the wing pieces 8, 8, the projecting piece 13 of the bridge member 10 is brought into contact with the magnet 17 to restrict further rotation, and at the same time, the iron piece 16 is attracted and rotated in the opposite direction. This shows a state in which free rotation is restrained, and at this time, the blade 8 is prevented from further rotation in the opening direction by the abutting portions 14 and 15, and the open posture is maintained. It turns out. In addition, when this wing piece 8 receives a force in the opposite direction in this state,
In other words, when the bridge member 10 is rotated in the closing direction,
As shown in FIG. 8, the engagement piece 18 provided at the lower end of the wing piece 8 is
This means that they can be freely rotated until they come into contact with the stoppers 19 that are juxtaposed and protruding from each other.

On the other hand, the frame part 4 provided on the back side of the mounting plate 2 communicates with the entry hole 5 provided in the mounting plate, and the hollow interior thereof has a support shaft supported at both ends by the left and right side walls 20, 20. 21 is passed horizontally, and a swing plate 22 is supported on this support shaft.

The rocking plate 22 has a substantially central portion of its length supported on a shaft so that its front and rear ends can swing up and down, and a weight 23 is embedded so that the front end 22a is always lowered. The front end 22a of this rocking plate is configured to penetrate into the entry pocket 3 through the entry port 5, and the rear end 22b abuts against the rear end 24 of the frame 4 to maintain a substantially horizontal position. When the posture is taken, this front end portion 22a intervenes between the left and right bridge members 10, 10, which are mounted on the support shaft 7 together with the wing pieces 8,
When the rear end is pushed down by an incoming ball to be described later and assumes a backward leaning position, it is designed to jump up and escape from between the pieces.

The device of the present invention has the above-mentioned configuration, and includes two wing pieces 8, which are rotatably supported on both sides of the opening of the entry pocket 3.
8 is in the upright state, that is, in the closed position shown in FIGS. 1 and 2, the rocking plate 22 abuts the rear end 22b against the rear end 24 of the frame 4 due to the weight of the front end 22a. It is placed in a horizontal position with a slight backward slope, and is interposed between two bridge members 10, 10 whose front ends 22a are supported on support shafts 7, 7.

FIG. 6 shows this state from behind, and the front end 22a of the swing plate 22 is located between the left and right bridge members 10, 10, as shown by the two-dot chain line, and the front end 22a of the swing plate 22 is located between the left and right bridge members 10, 10, The pieces 12, 12 are received on both side edges thereof to restrain inward rotation.

For this reason, each wing piece 8 whose abutting part 15 abuts against the abutting part 14 of the bridge member is urged to rotate outward due to the uneven distribution of the center of gravity. As a result of the restriction, rotation in the opening direction is restricted and the closed position is maintained.

In this state, when a ball enters between the left and right wing pieces 8, 8 that are upright, the ball hits the tip 2 of the rocking plate 22 that penetrates into the inside of the pocket.
2a, and then passes through the entry port 5 according to the slope and moves to the rear end of the swing plate 22, and uses its weight to convert the swing plate into a backward tilted position, and both pieces The front end portion 22a interposed between the members 10, 10 will be flipped up.

Therefore, the bridge member, whose rotation was restricted by the front end 22a, is forced to rotate inward under the weight of the wing pieces 8, which are set to always rotate in the opening direction, and the protruding piece 13 is rotated until it collides with the magnet 17, thereby opening both wing pieces, and at the same time, the iron piece 16 provided on the protruding piece 13 is attracted to the magnet 17, and its arbitrary rotation is restrained. ,
The other protruding piece 12 is maintained in an inwardly protruding state (FIG. 7).

At this time, the center of gravity of the rocking plate 22, which has been changed to a backward tilted position by the incoming ball, returns to the front end as the ball rolls out, so the front end 22a that has been jumped up descends, and the left and right bridge members However, since the rotation of the bridge member is restrained by the attraction of the magnet 17, the front end of the bridge member
It is received above and held in the position shown by the two-dot chain line in FIG.

Next, in this open position, when the next ball is received by the wing piece or directly enters the fly-in pocket 3, the ball falls onto the protruding piece 12 of the piece member that protrudes so as to close the middle of the pocket. In order to
Under the weight, the bridge member restrained by the magnet 17 is forcibly rotated outward, opening up the gap between the left and right bridge members, and the wing pieces interlocking with each other due to the abutment between the abutting portions 14 and 15. 8 will be rotated at the same time to return it to the closed position.

As the flying ball falls, the protruding piece 12 is released, and the tip 22a of the rocking plate, which was waiting above the protruding piece 12, descends and intervenes between the two pieces again.
In order to restrain its rotation, the closed wing pieces are restrained in that position and will maintain the closed position until the next ball hits.

As described above, the device of the present invention opens and closes the wing pieces 8, 8 according to the entry of a batted ball, and changes the entry conditions alternately between difficulty and difficulty. are related to each other through the bridge members 10, 10, and since the opening and closing of the blades is always controlled by the rotation of the bridge members, the blades can be opened and closed arbitrarily by the rotation of the blade alone. Can not.

Therefore, even if, for example, a ball other than an incoming ball collides with the wing piece in the open state and the wing piece rotates independently in the closing direction as shown in FIG.
Since the lowering of the tip of the rocking plate 22 is prevented by the suction of the swing plate 22, the swing plate 22 automatically returns to the open position, and does not change the closed position as in conventional devices.

In short, the device of the present invention is configured so that the blade always rotates in the opening direction by the uneven distribution of its center of gravity, and when the blade assumes an open position, the bridge member also follows that position, In addition, this is attracted by a magnet and restrained until the piece member is rotated in the closing direction by a regular flying ball, and it takes rocking to convert the wing piece from the closed state to the open position. Since it will not open unless the tip of the plate jumps up, accurate opening and closing movements are guaranteed, and arbitrary opening and closing due to unexpected shocks, etc. can be completely prevented.

In the above embodiment, the magnet 17 was provided on the opening edge of the fly-in pocket 3 on the base body side, and the adsorbing iron piece 16 was provided on the bridge member side, but it goes without saying that the same effect can be obtained even if the attachment is reversed. Furthermore, since the iron pieces 16 and the magnets 17 are used to restrain the bridge member 10 to the base body so that it does not rotate arbitrarily when the wing pieces are released, their attachment positions are not limited to one. .

In addition, an abutting portion 14 provided between the bridge member and the wing piece,
15 is also provided so that when the bridge member receives an incoming ball and rotates outward, the wing pieces 8 follow this and rotate in the closing direction and are held in the closing posture, so this relationship is established. The position and shape can be arbitrarily selected as long as the following can be obtained.
