Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lot of lottery pieces such as paper pieces placed in a hollow container, air is blown from the outside into the hollow container, and the lottery inside is disturbed by the blown air flow. The present invention relates to a lottery machine in which an arbitrary lottery piece is grabbed from outside and a lottery is performed.

[0002]

2. Description of the Related Art As a lottery machine or a game machine, a large number of paper pieces placed in a hollow container are blown up in an air stream and picked up by a hand inserted from the outside. No. 62-17897. The technology described in Japanese Utility Model Publication No. 62-17897 discloses a hollow container formed of a spherical container, injecting air from a lower air nozzle toward the bottom of the container to generate an air flow in the spherical hollow container. Then, a piece of paper is blown up, and the piece of paper falling from the ceiling is grabbed.

[0003]

However, in the above-mentioned conventional pneumatic game device, an air flow is generated from the bottom surface of the container to the inner surface of the container, and the air flow is generated only on the top surface (ceiling surface) of the container. The air is discharged through the formed air discharge port, and the paper pieces blown up by the air flow are dropped from the ceiling surface of the container. That is, the paper piece falling from the ceiling surface of the container is grasped by the hand inserted from the outside. Therefore, from the point of view of the game, not for the method of rotating the paper piece along the entire inner peripheral surface of the container by the air flow, but for the method of simply grabbing the paper piece falling from the ceiling surface, for those who play the game, You may find it boring or get bored quickly.

[0004] In addition, a rotatable receiving tray and a guide path for guiding an air flow along the inner surface are formed at the bottom of the spherical hollow container, so that the structure is very complicated. Further, there is a problem that a member for inserting a hand from the outside is formed in a tubular shape, and this member is projected into the inside of the hollow container so that the hand cannot be freely moved.

Further, in the above-mentioned Japanese Utility Model Publication No. Sho 62-17897, power is not always applied to the pneumatic game apparatus, and when the player uses the pneumatic game apparatus, the player turns on a switch to put air into the container. In this game, a game is performed in which a stream is raised to grab a piece of paper. Therefore, when the player does not use the game, there is no air flow in the container of the pneumatic game device, and no piece of paper is blown up. Can not. In other words, if the paper is not actually blown up by the air flow in the container, there is a problem that no device can be known and the function as a customer drawer is not exhibited at all.

Accordingly, the present applicant has already filed a patent application in order to solve the above problem (Japanese Patent Application No. 6-284315).
issue). In this application, a substantially spherical hollow container body is formed into a soccer ball shape using a plurality of flat panels, and an air stream is rotated in the hollow container body to form a paper piece (lottery piece) into the air stream. It is put on and rotated to grab a lottery piece. In this application, the position of the air outlet of the hollow container body is devised so that the rotation of the air flow inside can be improved, but each panel constituting the surface uses a flat plate, and the bottom surface The following problems were caused due to the flat shape.

That is, when the lottery piece is rotated by the air flow in the hollow container body, the lottery piece hits the surface of the panel and the lottery piece is easily damaged. In particular, because the bottom of the hollow container body is flat, it does not rotate in a manner that the lottery piece slides along the bottom surface, but the blown lottery piece rotates while the lottery piece collides with the bottom surface. ,
A new problem has arisen that the piece of whale is very severely damaged. Therefore, the lottery pieces do not last long and must be replaced immediately, which increases the running cost.

Also in the above-mentioned Japanese Utility Model Publication No. 62-17897, since many members such as a saucer, a guideway, and an arm insertion cylinder are arranged in the hollow container, a lottery piece crashes into them. There is also the problem of severe damage to the lotus pieces.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and has a simplified structure of a hollow container main body, and reduces damage when a lottery piece in the hollow container main body is rotated by an air flow. It is an object of the present invention to provide a lottery machine which is very interesting and exciting for a person who draws lottery pieces and has game characteristics.

The lower hemisphere 4 of the hollow container body 2 is fixed by a holding portion (not shown) provided inside the pedestal 31, and on the bottom surface of the pedestal 31 below the lower hemisphere 4. A blower 20 is provided. One of the blowers 20 is a suction port 21, and the other discharge port 22 is provided with an air duct 23. The fan of the motor of the blower 20 is a so-called sirocco fan, but may be a propeller fan. In addition, although the suction port 21 of the blower 20 is provided on the side surface as shown in FIG. 1, only the top surface, or both the side surface and the top surface may be used as the suction port 21.

By the way, as shown in FIG. 1 and FIG. 11 showing another embodiment, the pedestal 31 is formed in a substantially bowl shape having an open upper surface, and three or more leg portions 32 are formed from the side surface. ing. A caster 33 is attached to the tip of the leg portion 32 so that the pedestal 31, that is, the lottery machine body 1 can be smoothly moved. Although four legs 32 are formed in the case of FIG. 11, three legs may be formed. When the number of the legs 32 is three, the stability of the pedestal 31 is very good. The lower hemisphere 4 is inserted through the opening on the upper surface of the pedestal 31, the lower hemisphere 4 is fixed, and the upper hemisphere 3 is placed from above the lower hemisphere 4 and the upper hemisphere 3
And are detachably fixed by means such as bolting or concavo-convex fitting to form a spherical hollow container body 2.

Here, the tip of the air duct 23 is arranged so as to project into the hollow container body 2 as shown in FIGS. 2 and 3, and the tip is used as a blowout portion 26. The opening at the lower end of the outlet 26 is the outlet 24. The blower 20 is
The rectifying section 2 is provided to the blowing section 26 of the air duct 23 so that air from the air duct blows out along the concave bottom surface of the lower hemisphere 4.
5 are formed. Although FIG. 2 shows a case where the blowout portion 26 of the air duct 23 projecting into the lower hemisphere 4 is formed integrally with the air duct 23, the blowout projecting into the lower hemisphere 4 is shown. Part 26 to the air duct 23
It may be formed separately from. Air duct 2
3 is formed in a substantially rectangular tube shape, and the blowout portion 26 forming the rectifying portion 25 is also formed in a substantially rectangular tube shape as shown in FIG. The rectifying section 25 of the blowing section 26 is formed so as to be substantially parallel to the inner surface of the lower hemisphere 4. The rectifying section 25 rectifies the air from the air duct 23, and blows out the air from the outlet 24, It flows along the bottom surface of the lower hemisphere 4. Then, as shown in FIG. 1, the air flow rotates so as to draw a circle.

The upper hemisphere 3 of the hollow container body 2 is detachably fixed to the lower hemisphere 4, and the hollow container body 2
A large number of lottery pieces 7 made of paper pieces are provided in the inside of.
Then, the air blown from the blower 20 is guided into the air duct 23, and is rectified downward by the rectifying unit 25 of the blowing unit 26.
From the outlet 24 of the lower hemisphere 4 along the concave bottom surface. And it becomes the air flow which rotates in the hollow container main body 2. The lottery piece 7 is blown up by the air flow of the blown air,
The lottery piece 7 rotates inside the hollow container body 2 on the air flow. The rotating lottery piece 7 is grasped by inserting a hand from the outlet 8.

Here, in the hollow container body 2, the outlet 24
Although the air blown out of the container rotates as a substantially circular air flow, a part of the air is discharged from a large number of air exhaust ports 6 perforated on the upper peripheral surface of the hollow container body 2. The size, position, number, and the like of the air exhaust ports 6 are related to the number and weight of the lottery pieces 7 to be rotated by being put on the air flow.
For example, when the air exhaust port 6 is perforated only on the upper surface of the hollow container main body 2, it is difficult to form a rotating air flow. Therefore, in this embodiment, a large number of air exhaust ports 6 are perforated around the upper portion of the hollow container body 2 to obtain a rotating air flow. In addition, an air exhaust port 6 may be formed in the upper surface of the hollow container body 2. The diameter of the air exhaust port 6 is preferably 5 to 8 mm, and the position and the number of the air exhaust port 6 are appropriately changed according to the material, weight, size, and the like of the lottery piece 7. .

Explaining the whole operation, as described above, a large number of lottery pieces 7 are put in the hollow container body 2 in advance, the power of the blower 20 is turned on, and the blower 20 passes through the air duct 23 to the tip side. Air is blown from the air outlet 24 toward the bottom surface in the hollow container body 2. Then, as indicated by an arrow in FIG. 1, an air flow is formed along the concave inner surface, the ceiling surface, and the other inner surface of the hollow container body 2. This air flow flows with a certain width in the hollow container main body 2, and the width becomes a width corresponding to the width of the outlet 24, and by changing the width of the outlet 24, the width of the air flow also increases. It can be changed as appropriate.

A large number of lottery pieces 7 are placed on the air flow to rotate, and a lot of lotus pieces are put on the air flow in the hollow container main body 2 by putting a hand from the outside through the outlet 8 and rotating. Grab 7 In this embodiment, the number of the outlets 8 is three. However, four or eight times the number of the outlets 8 may be formed. Therefore, by forming a large number of outlets 8, it is possible to simultaneously participate in the lottery for grabbing lottery pieces 7 by the number corresponding to the number of outlets 8. Of course, since the lottery machine main body 1 is always operated, a person can instead insert his hand into the outlet 8 and grab the lottery piece 7. In this way, many people can grab the lottery piece 7 at the same time, so even if there are many people who perform lottery, there is no need to wait for a long time,
You can join the lottery immediately after waiting a short time.

Further, unlike the conventional example, the lottery machine main body 1 is always operated and the lottery piece 7 is always rotated by riding the air flow. Therefore, even when a person does not actually perform the lottery. If a general person looks at the lottery machine body 1, he or she will be interested. Therefore, if the lottery machine main body 1 is put in the store or at the storefront and operated, the function of attracting customers can be sufficiently exhibited.

In addition, in this embodiment, since the bottom surface of the hollow container body 2 is formed in a concave shape, the rotating lottery piece 7 slides on the air flow even at the bottom of the hollow container body 2. Rotate to do. Therefore, the damage to the lottery piece 7 is much less than in the conventional case where the bottom surface is flat, and the life of the lottery piece 7 is 7 to 12 times that of the conventional case.
I came to have it for about twice as long. So, for example, 4
Although the lottery piece 7 was replaced in about 5 days, it was not necessary to replace it for one month or more, and the running cost could be reduced.

By the way, as described above, the air volume and the air velocity of the air flow in the hollow container body 2 may be kept constant, but as described below, the air volume and the air velocity of the air flow in the hollow container body 2 will be described. May be variable. That is,
A switch for changing the rotation speed of the motor of the blower 20 may be provided on an operation panel (not shown), and the rotation speed may be changed in several steps or steplessly by operating this switch.

Further, a flat plate-like control plate (not shown) which is slidable is provided on either or both of the suction port 21 and the discharge port 22 of the blower 20, and the sliding position of the control plate (suction port 21). The air volume and speed from the air outlet 24 of the air duct 23 can be adjusted according to the closed position of the discharge port 22).

In the above example, as means for adjusting the air flow rate and the air velocity in the hollow container body 2, the rotation speed of the motor of the blower 20 is controlled, and the suction port 21 and the discharge port 22 of the blower 20 are provided. Although any one of the slide positions of the control plate has been described, these may be combined to adjust (adjust) the air volume and speed of the air flow in the hollow container body 2. By adjusting the air flow in the hollow container body 2 in this way, the number of the lottery pieces 7 inserted in the hollow container body 2, the size of the lottery piece 7, the material of the lottery piece 7, It is possible to perform fine control so that the rotation of the lottery piece 7 due to the airflow can be performed evenly with respect to the weight of the type depending on the weight.

As a typical kind of the lottery piece 7, there is a triangular piece of paper, but the shape of the lottery piece may be any, and the material of the lottery piece is not limited to the paper piece. Anything can be used as long as it can be rotated in the hollow container body 2 by the air flow. For example, a thin piece of wood may be used.

The height of the lottery machine main body 1 is 1.5M or more.
It is about 1.8M, which is almost the same height as a person. However, the present invention is not limited to a specific height, and the present invention can be applied regardless of the height or size.

Although the air duct 23 is formed in a rectangular tube shape, it may be formed in a cylindrical shape or may be formed in a bellows shape so as to have flexibility. FIG. 6 shows a case where the air duct 23 is formed in a cylindrical shape, in which a plate-shaped rectifying portion 25 is fixed to the opening surface at the tip of the air duct 23, and the outlet port 24 is formed by opening the lower portion of the tip. It is. By adjusting the protruding angle of the air duct 23 into the hollow container main body 2 and the angle of the rectifying section 25, the outlet 2
Air is blown out along the bottom surface of the lower hemisphere 4. The rectifying section 25 shown in FIG.
Since the front end opening surface is simply closed, the structure can be simplified and the cost can be reduced as compared with the case shown in FIG.

In FIG. 7, the air duct 23 is inserted into the hollow container main body 2 from the lateral direction, the rectifying portion 25 is fixed to the opening surface of the tip of the air duct 23, and the lower surface of the tip is opened as in the case of FIG. The air outlet 24 is used. In this configuration,
The air from the outlet 24 can be blown out along the bottom surface of the hollow container body 2 simply by inserting the air duct 23 into the hollow container body 2 from the lateral direction. And assembly work becomes very simple.

In FIG. 8, the air duct 23 is inserted obliquely downward into the hollow container body 2 with the opening at the tip of the air duct 23 as the outlet 24. In this case,
A portion on the tip end side of the air duct 23 is a rectification unit 25,
By simply inserting the air duct 23 into the hollow container main body 2 so that the side surface at the tip of the air duct 23 is substantially parallel to the inner surface of the hollow container main body 2, it is possible to easily obtain an air flow blown from the inner surface to the bottom surface. Can be. In particular, a member as the rectifying portion 25 is not required, and a simply rotating air flow can be obtained simply by inserting the air duct 23 into the hollow container body 2.

FIG. 9 shows the air duct 23 with the hollow container body 2
Is inserted obliquely upward from the bottom surface of the air duct 23. In this case as well, the opening face at the front end of the air duct 23 is the outlet 24, and the portion on the front end side is the rectifying section 25. Therefore, simply by inserting the air duct 23 into the hollow container main body 2 as in the case of FIG. 8, it is possible to obtain an easily rotating air flow. Note that, also in the case of FIG. 9, the air from the outlet 24 can obtain a circular air flow from the bottom surface of the hollow container body 2 to the inner surface of the side portion, the ceiling surface, the inner surface of the other side portion, and the bottom surface. it can.

Although the air duct 23 shown in FIGS. 6 to 9 has a cylindrical shape, it may have a rectangular tube shape.

(Second Embodiment) By the way, although the hollow container body 2 of the lottery machine body 1 shown in FIG. 1 is spherical,
In this case, since the air flow is circular, the lottery piece 7 is only swung around, and it cannot be denied that the change or unexpectedness is poor. Therefore, FIG. 10 shows the lottery machine body 1 according to the second embodiment. In this embodiment, the upper hemisphere 3 of the hollow container main body 2 is not a hollow spherical shape but a cylindrical shape so that the hollow portion is made higher and the butterfly piece is disturbed on the lottery piece 7 in the hollow container main body 2. It is a thing. The shape of the upper hemisphere 3 of the hollow container main body 2 is only a cylindrical shape, and the structures of the lower hemisphere 4 and the pedestal 31 are the same as those shown in FIG.

FIG. 11 is a perspective view of the whole lottery machine main body 1,
FIG. 12 is an exploded perspective view. In this embodiment, two upper and lower outlets 8 are formed at three positions of the upper hemisphere 3, and the structure is the same as that of FIG. 4 as shown in FIG. However, in this embodiment, since the upper hemisphere 3 is not curved in the vertical direction, the packing 10 is drawn straight in the vertical direction in FIG. In addition, the position and the number of the outlets 8 are not limited to those shown in the figure, and may be formed to be smaller or larger than the figures. Further, since the upper surface of the upper hemisphere 3 is open, a disc-shaped upper panel 15 is detachably mounted. This upper panel 1
A large number of air exhaust ports 6 are bored in 5, and a large number of air exhaust ports 6 may be provided around the upper hemisphere 3 as well as the upper panel 15. Further, the air exhaust port 6 may be formed only around the upper hemisphere 3 without forming the air exhaust port 6 in the upper panel 15.

Here, in the air flow in the hollow container body 2 of the lottery machine body 1, in the lower hemisphere 4, air is blown along the bottom surface from the air outlet 24 of the air duct 23, and is further directed upward. It becomes the airflow that is blown up. The lottery piece 7 rides on this air flow and is blown up to the vicinity of the upper panel 15, and thereafter the lottery piece 7 falls like a butterfly. As a result, since the lottery piece 7 disturbs like a butterfly in the hollow container body 2, even when inserting and grasping a hand from the outlet 8, it is unexpected and very interesting.

Although the upper panel 15 of the hollow container body 2 has a flat plate shape, a hollow hemisphere like the lower hemisphere 4 may be used. 10 and 11, the shape of the leg 32 of the base 31 of the lottery machine body 1 is slightly different from the shape of the lower end of the leg 32, but this shows another shape of the leg 32. is there.
