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. In addition, a member for inserting a hand from the outside is formed in a cylindrical shape, and this member is protruded to the inside of the hollow container, so that there is a problem that the hand cannot be moved freely.

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, since the bottom of the hollow container body is flat, the lottery pieces do not rotate in such a way as to slide along the bottom, but the blown-up lottery pieces rotate while hitting the bottom, so that the lottery pieces are rotated. A new problem arises in that the damage to the steel is very severe. Therefore, the lottery pieces do not last long and must be replaced immediately, which increases the running cost.

In the above-mentioned Japanese Utility Model Publication No. Sho 62-17897, many members such as a saucer, a guideway, and an arm insertion cylinder are provided in the hollow container. There is also a problem that the lottery pieces are seriously damaged.

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 the bottom of the pedestal 31 below the lower hemisphere 4 is 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, the base 31 is 1 and to be described later
As shown in FIG. 11 showing an embodiment of the present invention , the upper part is formed in a substantially bowl shape with an upper surface opened, and
Are formed. A caster 33 is attached to the tip of the leg 32, and the pedestal 31
That is, the movement of the lottery machine main body 1 can be performed smoothly. 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 fixed by inserting the lower hemisphere 4 from the opening on the upper surface of the pedestal 31, and the upper hemisphere 3 is placed on the lower hemisphere 4.
The upper hemisphere 3 and the upper hemisphere 3 are detachably fixed by means such as bolting or concave and convex fitting to form a spherical hollow container body 2.

Here, the distal end of the air duct 23 is disposed so as to protrude into the hollow container body 2 as shown in FIGS. 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. FIG. 2 shows a case in which the air duct 23 projecting into the lower hemisphere 4 is formed integrally with the air duct 23, but the air duct 23 projecting into the lower hemisphere 4 is shown in FIG. Part 26 to air duct 23
And may be formed separately. 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 main body 2 is detachably fixed to the lower hemisphere 4.
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 air outlet 24 is provided.
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. .

The whole operation will be described. As described above, a large number of lottery pieces 7 are put in the hollow container body 2 in advance, and the power of the blower 20 is turned on. The air is blown out from the 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 rotate on the above-mentioned air flow. The lottery pieces 7 are rotated on the air flow inside the hollow container body 2 by hand from outside through the outlet 8. 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 constantly operated and the lottery piece 7 is constantly rotating in the air flow, so that even if a person is not actually performing the lottery, When a general person looks at the lottery machine main body 1, the user becomes 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 the present invention, since the bottom surface of the hollow container main body 2 is formed in a concave shape, the rotating lottery piece 7 slides on the bottom of the hollow container main body 2 with the air flow. To rotate. Therefore, damage to the lottery piece 7 is much smaller than in the conventional case where the bottom surface is flat, and the life of the lottery piece 7 is about 7 to 12 times longer than in the related art. Thus, for example,
Although the lottery pieces 7 were replaced in five days, there is no need to replace them for more than one month, and running costs can be reduced.

As described above, the air volume and the air velocity of the air flow in the hollow container body 2 may be kept constant. However, as described below, the air volume and the air velocity of the air flow in the hollow container body 2 will be described below. May be varied. 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.

By adjusting the air flow in the hollow container main body 2 in this way, the number of the lottery pieces 7 inserted into the hollow container main body 2, the size of the lottery pieces 7, the size of the lottery pieces 7, It is possible to perform fine control so that the rotation of the lottery piece 7 due to the air flow can be made evenly with respect to the lightness or the like depending on the type of material.

As a representative type of the lottery piece 7, there is a triangular lottery of a paper piece, but the shape of the lottery piece may be any shape, and the material of the lottery piece is not limited to a paper piece. Any material may be used as long as it rotates inside the hollow container body 2 by an air flow. For example, a thin piece of wood may be used.

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

Although the air duct 23 is formed in the shape of a square tube, 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.

FIG. 7 shows that the air duct 23 is inserted into the hollow container main body 2 from the lateral direction, and the rectifying section 25 is fixed to the opening surface of the tip end of the air duct 23 in the same manner as in FIG. The 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.

FIG. 8 shows the air duct 23 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 connected to 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. In the case of FIG. 9 as well, 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, the ceiling, the inner surface of the other side, and the bottom. it can.

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

( First Embodiment of the Present Invention) Next, a first embodiment of the present invention will be described with reference to the drawings.
explain. By the way, although the hollow container main body 2 of the lottery machine main body 1 shown in FIG. 1 has a spherical shape, in this case, since the air flow is circular, the lottery piece 7 only rotates with gurgle, I can't deny the poor nature. Therefore,
FIG. 10 shows a lottery machine main body 1 according to the embodiment of the present invention . In this embodiment, the upper hemisphere 3
Is not a hollow spherical shape but a cylindrical shape, and the hollow portion is made higher so that the butterfly 7 disturbs the lottery piece 7 in the hollow container body 2. It should be noted that the shape of the upper hemisphere 3 of the hollow container body 2 is merely cylindrical, and the lower hemisphere 4 and the pedestal 3
The configuration such as 1 is the same as the configuration shown in FIG.

FIG. 11 is a perspective view of the whole lottery machine 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
5 is provided with a large number of air exhaust ports 6, and may be provided not only with the upper panel 15 but also around the upper hemisphere 3. 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, the air flow in the hollow container main body 2 of the lottery machine main body 1 is such that air is blown from the outlet 24 of the air duct 23 along the bottom surface in the lower hemisphere 4 and further upward. The air flow 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.

In FIGS. 10 and 11, the shape of the lower end of the leg 32 in the leg 32 of the base 31 of the lottery machine main body 1 is slightly different. It is shown.

( Second Embodiment) FIGS. 14 and 15 show a second embodiment. In this embodiment, the shape of the hollow container body 2 is the same as that of FIG. 12, but the shape of the pedestal 31 is different. That is, the outer shape of the pedestal 31 is an octagon, and the internal configuration is the same as that of the above-described embodiment, and therefore the description is omitted.

In each of the above embodiments, the case where the position of the air outlet 24 is located near the center of the hollow container body 2, or slightly below or at the bottom of the hollow container body 2 has been described. However, the present invention is not limited to this. For example, blowing the position of the air outlet 24 may be disposed above the central portion of the hollow container body 2, to a stomach portion of the hollow container body 2 of the upper and the upper panel 15 when the cylindrical in FIG. 10 An outlet 24 may be provided. That is, the position of the air outlet 24 may be provided anywhere so as to form an air flow in the hollow container body 2. In addition, the blowing section 26
The shape of the air duct 23 and the like can be applied not only to the case of a cylindrical shape or a rectangular tube shape but also to any other shape, for example, any shape such as a pentagon or hexagonal cross section.

[0043]

According to the lottery machine according to the first aspect of the present invention, since the lower portion of the hollow container main body has a hollow substantially spherical shape, the bottom surface of the hollow container main body becomes a spherical concave surface, and the inside of the hollow container main body is reduced. Even if the lottery pieces are rotated by the air flow blown out from the outlet, the lottery pieces rotate so as to slide in the hollow container body, so that the lottery pieces are less damaged,
The service life can be extended about 7 to 12 times as compared with the related art in which the bottom surface is flat. Also, the structure of the hollow container main body is different from the conventional one, and no other members are mainly arranged in the hollow container main body, so that the configuration is simplified and the cost can be reduced. Further, the air from the blower is blown out from the outlet to form an airflow flowing along the concave bottom surface of the hollow container body, and a lightweight lottery piece is blown upward on the airflow, and the airflow is increased. The lottery pieces fall from the top while fluttering like a butterfly and flutter like a butterfly, and the person who pulls the lottery piece inserts his hand from the opening into the hollow container body and removes the rotating lottery piece. grab. This makes it possible to provide a lottery machine having both an entertaining sensation and an excitement sensation gameplay of grabbing a random lottery piece in the hollow container main body, thereby giving people interest and real pleasure. Therefore, it is possible to provide a more interesting and unexpected lottery machine than when the lottery piece is simply rotating. In addition, since the lottery pieces are constantly disturbed, it is possible to make people interested and to fully exhibit the function of attracting customers.

According to the lottery machine of the second aspect, since the air from the air outlet is provided with a rectifying portion at the outlet at the tip of the air duct so that the air flows from the inner surface to the bottom surface of the hollow container body. The air from the outlet can be reliably made to flow from the inner surface to the bottom surface of the hollow container body from the outlet. for that reason,
Since the lottery piece at the bottom of the hollow container body rotates so as to slide along the bottom surface, damage to the lottery piece can be greatly reduced as compared with the related art. It is easy to blow up the piece upward.

Further, according to the lottery machine of the third aspect ,
Since a cylindrical air duct with an open end face is arranged so as to protrude into the hollow container main body so as to be substantially parallel to the inner surface of the hollow container main body, air flowing from the air outlet along the bottom surface is provided. No rectifying section is required to form the flow, so that the configuration of the air duct outlet can be simplified. Therefore, the construction of the air duct and the construction on the hollow container body are facilitated.

According to the lottery machine of the fourth aspect, by variably controlling the rotation speed of the motor constituting the blower, it is possible to change the amount and speed of the air flow in the hollow container body. The rotation of the lottery piece can be arbitrarily controlled according to the variation of the lottery piece size or size, or the variation of the lottery piece rotation, thereby providing a more interesting and varied lottery machine.

Further, according to the lottery machine of claim 5 ,
Since a plurality of outlets are provided around the hollow container main body, many people can grab the lottery pieces in the hollow container main body at one time, for example, a lot of people performing lottery by a lottery machine Even in the state, the lottery can be performed quickly, and the waiting person does not feel irritated.

According to the lottery machine of the sixth aspect, the packing at the outlet is substantially flush with the surface of the hollow container body.
The lottery pieces rotating or disturbing in the hollow container body do not collide with the packing, so that damage to the lottery pieces can be extremely reduced. Also, unlike the related art in which the outlet is protruded into the hollow container body, the degree of freedom of the hand inserted through the outlet becomes extremely large, and it becomes interesting to grasp the lottery pieces.
