Description

[Detailed Description of the Invention] Conventionally, there have been so-called chuuripu, etc., in which the reception opening of the batted ball opens wide each time a prize is won, as a prize-winning device that changes the receiving state of a batted ball. Ta. Moreover, as the winning state conversion means, a crank or cam mechanism that uses the weight of the ball is used to operate in direct conjunction with each other, which has the disadvantage of requiring time and effort to manufacture and increasing the failure rate.
In addition, not only delicate adjustments are required during manufacture to ensure smooth interlocking operations, but constant adjustments are also required during maintenance and inspection after use.

In view of the above, the present invention and another invention have a simple structure in which a rotating body having large and small sockets rotates 90 degrees in response to the winning of a batted ball, thereby changing the receiving state of the batted ball. The purpose of this invention is to provide a revolving prize winning device that is highly entertaining.

Hereinafter, an explanation will be given based on drawings showing an example of implementation.

In FIGS. 1 and 2, a support shaft 2 is installed vertically on the surface of a board 1 to be attached to a game board, and a rotating body 3 is rotatably pivoted to this support shaft 2. Rotating body 3

A small socket 4 which cannot easily receive a batted ball and a large socket 5 which can easily receive a batted ball are provided on the periphery of the rotating body 3, displaced by 90 degrees about the support shaft 2. The small socket 4 shown in the embodiment is U-shaped and has both wings widened slightly to the left and right, and the large socket 5 is also U-shaped and has both wings widened widely to the left and right. Both the small socket 4 and the large socket 5 are formed so as to face the lower edge of the prize opening 24 when rotated.

The rotating body 3 is provided with a weight for applying a rotational moment. In the embodiment, a weight portion 6 is provided on the lower back side of the rotating body 3, and a weight portion 7 is also provided on the left back side of the rotating body 3. The lower weight part 6 and the left weight part 7 of the rotating body 3 are displaced by 90 degrees about the support shaft 2.

Permanent magnets having the same polarity on the substrate 1 side are fixed to the left weight portion 7 and the lower weight portion 6 so as to slightly protrude toward the substrate 1.

The permanent magnets constituting the first magnetic parts 8' and 8 are arranged to be displaced from each other by 90 degrees with the support shaft 2 as the center.

The lower weight portion 6 and the left weight portion 7 including the permanent magnets 8 and 8' function as weights that bias the rotating body 3 to rotate. For example, when the rotating body 3 is set in a free state in FIG. 1, the rotating body 3 is rotated counterclockwise by the weight portion 7 on the left side. The weights 6 and 7 may be formed so as to function similarly to the decorative plate itself when the decorative plate is attached to the front surface of the rotating body 3. In the embodiment, the weight of the magnets forming the first magnetic parts 8', 8 is used as a weight.

An arcuate guide hole 10 having an opening of at least 90 degrees around the support shaft 2 is provided on the back surface of the rotating body 3.
The protrusion 11 has a tip inserted into the guide hole 10.

If the opening of the guide hole 10 with respect to the support shaft 2 is slightly larger than 90 degrees, the rotating body may rotate smoothly.

For convenience of explanation, when the large socket 5 of the rotating body 3 is located on the right side, it is referred to as the normal position state, and from the normal position, the large socket 5 is located vertically upward by rotating 90 degrees counterclockwise. This is called the antiposition state. FIG. 1 shows the rotating body 3 in the normal position, and FIG. 4 shows the rotating body 3 in the reverse position.

In FIGS. 1 and 4, on the surface of the substrate 1,
When the lower weight part 6 and the left weight part 7 are in the oriented state and the reversed state, respectively, the protruding ends of the permanent magnets 8 and 8' fixed to the weight parts 6 and 7 on the board side are engaged with each other.

In this case, the front blade 18 and the weight blade are approximately horizontal in the front and back, and the lower blade 19 hangs downward. FIG. 5 shows the position of the blades when the rotating body 3 is kept in the opposite position. In this case, the front blade 18 and the weight blade 20 are vertically substantially vertical, and the lower blade 19 is located almost on the horizontal line.

A holding body 15 is provided between the front blade 18 and the lower blade 19.

shall be. Further, the left side 23 of the third magnetic part has the same polarity (N pole) as the first magnetic parts 8', 8, and the right side 23' has a different polarity (S pole).

As shown in FIG. 2, the rotating body 3 and the rotating member 17
When in the normal position state, the left first magnetic part 8' of the adjacent rotating body 3 and the left second magnetic part 22 of the front blade 18 generate an attractive force due to different polarities, and this attraction causes the rotating body to 3 slides backward on the support shaft 2, and the rotating body 3
The first magnetic part 8' on the left side of the rotating body 3 engages with the left engaging recess 12' on the surface of the substrate 1, and the first magnetic part 8 below the rotating body 3 engages with the central engaging concave part 12, and the rotating body 3 It can be stopped reliably.

Next, the rotating member 1 is rotated while the rotating body 3 remains in the normal position.
7 rotates 90 degrees upward (Fig. 5), the first magnetic part 8' (N
pole) and the lower blade 1 moved to the corresponding position
A repulsive force is generated between the third magnetic part 9 and the left 23 (N pole) due to the same polarity. Due to this repulsion, the left first magnetic part 8' of the rotating body 3 is moved to the left engaging recess 1.
2', and at the same time, the lower first magnetic part 8 of the rotating body 3 also separates from the central engagement recess 12.
The rotating body 3 slides in front of the support shaft 2 and is no longer engaged with the substrate 1, so that it is momentarily in a free state. Then, at the next moment, the rotational moment due to the weight between the left weight part 7 and the first magnetic part 8' of the rotary body 3 and the repulsive force acting between the same poles combine, and the rotary body 3 becomes repulsive. Rotate clockwise. With this rotation, when the lower first magnetic part 8 (N pole) of the rotating body 3 approaches the left engagement recess 12'', the right magnetic part 8 of the lower blade 19 located on the back side of the engagement recess 12'' 3 magnetic part 23' (S pole) due to the attraction effect due to the different polarities, and the rotating body 3
The first magnetic part 8 on the lower side of the rotor 3 engages with the right engagement recess 12''.At the same time, the rotating body 3 slides rearward of the support shaft 2, and the first magnetic part 8' on the left side of the rotating body 3 also engages with the right engaging recess 12''. It engages with the central engagement recess 12 and reliably engages with the substrate 1.
In other words, the rotating body becomes inverted (FIG. 4).

Next, the rotating member 1 is rotated while the rotating body 3 remains in the reversed position.
7 rotates 90 degrees downward (Fig. 2), the first magnetic part 8 (N pole) of the rotating body 3 located in the right engagement recess 12''
A repulsive force due to the same polarity is generated between the right 22' (N pole) of the second magnetic part of the front blade 18 which has moved to the corresponding position. Due to this repulsive action, the lower first magnetic part 8 of the rotating body 3 moves into the left engaging recess 12''.
At the same time, the first magnetic part 8' on the left side of the rotary body 3 also disengages from the central engagement recess 9. As a result, the rotary body 3 slides forward of the support shaft 2 and is no longer engaged with the substrate 1. The connection is removed and you are in a free state for a moment. Then, at the next moment, the rotational moment due to the weight consisting of the lower weight part 6 and the first magnetic part 8 of the rotating body 3 and the repulsive force acting between the same poles combine, and the rotating body 3 rotates clockwise. Rotate to. With this rotation, when the left first magnetic part 8' (N pole) of the rotating body 3 approaches the left engagement recess 12', the left side of the front blade 18 located on the back side of the engagement recess 12' The first magnetic part 8' on the left side of the rotating body 3 engages with the left engaging recess 12' due to the attraction effect due to the different polarities between the second magnetic part 22 (S pole) and the second magnetic part 22 (S pole). At the same time, the rotating body 3 slides rearward of the support shaft 2, and the first magnetic part 8 below the rotating body 3 also engages with the central engaging part recess 11, thereby reliably engaging with the substrate 1.
That is, the rotating body 3 becomes in a normal position (FIG. 2).

The forward sliding range of the rotating body 3 on the support shaft 2 is as follows:
First magnetic parts 8', 8 protruding from the tips of the weight parts 6, 7
The distance may be sufficient as long as it can be separated from the engaging recesses 12, 12', 12''.

Next, the rotating means for the rotating member will be explained.

In FIG. 2, when the rotating body 3 and the rotating member 17 are in the normal position, the winning ball 14 that has entered the winning opening 24 of the board 1 flows into the upper surface of the front blade 18 and pushes down the front blade 18 with its own weight. However, the rotating member 17 cannot rotate because the lower blade 19 is in contact with the stop rod 21, and the winning ball 14 rolls from above the front blade 18 onto the weight blade 20, pushing the weight blade 20 downward. to rotate the rotating member 17. Due to this rotation, the rotating member 17 brings the weight blade 20 into contact with the stop rod 21 and becomes inverted (FIG. 5). The winning balls 14 are then discharged from a first outlet 25 formed in the holding body 15.

In FIG. 5, the winning ball 14 that enters next falls onto the lower blade 19, pushes down the lower blade 19, and rotates the rotating member 17. With this rotation, the rotating member 17 brings the lower blade 19 into contact with the stop rod 21 and returns to the normal position. The winning balls 14 are then discharged from a second outlet 26 bored in the bottom of the holder 15.

The rotating member 17 may be rotated using external action. That is, the interlocking rod 27 is attached to the rotating member 17, the tip of the interlocking rod 27 extends outside the holder 15, and the rotating member 17 is rotated via the interlocking rod 27. In the embodiment, as shown in FIG.
0 is provided with an interlocking rod 27, and this interlocking rod 27 is made to protrude from a hole bored in the side wall of the holder 15. The hole is formed so that the interlocking rod 24 can move freely as the weight blade 20 rotates.

By connecting this interlocking rod 27 to another drive source, for example, an electric drive source such as a solenoid, or a winning state conversion operation rod of another winning device, the rotating member 17 can be forcibly rotated.

Note that 28 in FIGS. 2 and 3 is a ball introduction hole. The ball introduction hole 28 is located in the holder 1 above the weight blade 20.
5, and is for guiding winning balls that have flowed in from other winning holes onto the spindle feather 20. Thereby, even if a prize is won with a device other than the present prize winning device, the winning mode of the present device can be changed.

Next, another means for rotating the rotating body is provided in a seventh manner.
This will be explained with reference to FIG.

The means for rotating the rotating body 17 of the invention includes second magnetic parts 22, 22' and a third magnetic part having opposite polarities.
The rotating member 17 having the magnetic parts 23, 23' is rotated by utilizing the falling of the winning ball 14, and alternately exerts different magnetic effects on the first magnetic parts 8, 8' of the rotating body 3. Therefore, the rotating body 3 was rotated, but the means described next uses an electromagnet 30 instead of the rotating member 17, and reverses the polarity of both poles of the electromagnet 30 as appropriate depending on the winning mode. By this,
causing the second and third magnetic parts to appear electrically;
The magnetic pole changing mechanism 33 alternately exerts different magnetic effects on the first magnetic parts 8, 8' of the rotating body 3.

The electromagnet 30 has one magnetic pole attached to the left first magnetic part 8' when the rotating body 3 is in the normal position, and the other magnetic pole to the lower first magnetic part 8' when the rotating body 3 is in the opposite position. 8 are placed on the back side of the substrate 1 so as to be in positions where magnetic action is exerted on each of them. In the embodiment, the first magnetic parts 8', 8 are provided close to the left and right engaging recesses 12', 12'' that are engaged in the oriented state and the reversed state.

In order to electrically expose the second and third magnetic parts, a magnetic pole control part 31 is provided in the power supply circuit of the electromagnet 30. The magnetic pole control section 31 has an electronic switch that switches the direction of the current in the power supply path in response to a signal from a winning ball detector (not shown) that electrically detects winning balls.

When the magnetic poles on the substrate surface side of the left 8' and lower 8 of the first magnetic section are N poles, in order to maintain the rotating body 3 in the oriented state, the electromagnet 30 corresponding to the left first magnetic section 8' is required. The pole of the electromagnet 30 corresponding to the lower first magnetic portion 8 is set as the S pole in order to maintain the rotating body 3 in the opposite position.

When rotating the rotating body 3 from the normal position to the reversed position, the pole of the electromagnet 30 corresponding to the first magnetic portion 8' on the left is changed from the S pole to the N pole, and the rotating body When rotating the electromagnet 3 from the inverted state to the orientated state, the pole of the electromagnet 30 corresponding to the lower first magnetic portion 8 is changed from the S pole to the N pole.

The operation of the rotating body 3 by changing the magnetic pole of the electromagnet 30 is the same as that by the rotating member 17 described above.

Since this invention utilizes the magnetic action of an electromagnet, by applying appropriate electrical means,
There is an advantage that the conversion mode can be freely set in advance according to the game mode regardless of whether or not winning balls enter the device.
