Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a crane game in which prizes such as toys and sweets are grabbed using a crane-type prize capturing device that is positioned by the player's operations. Regarding machines.

[Prior Art] A conventional crane game machine includes a prize mounting surface on which a large number of prizes are placed in a housing whose upper part is covered with a transparent cover, a crane serving as a prize capturing device having a plurality of claws, and the crane. It is known that the player is provided with a drive mechanism and an operating section including a coin insertion slot and a start switch operated by the player on the outer surface of the housing. When playing the game, the player inserts a coin and operates the operating section to move the crane to an arbitrary position on the prize placement surface and cause the claws of the crane to capture the prize. If the claw successfully grasps the prize, the prize is ejected outside by the crane, allowing the player to obtain the prize.

As a simplified structure of such a crane game machine, there is also a crane game machine in which a turntable is installed in a housing and a large number of prizes are placed on the turntable. In this case, the player can horizontally rotate the turntable by operating the handle, thereby positioning any prize on the turntable below the crane.

[Problems to be solved by the invention] However, in the above-mentioned simple crane game machine, if a gear mechanism linked to the operation handle is used as a drive means for rotating the turntable, it is difficult to replenish prizes or repair, for example. Therefore, after removing the turntable from its installation position and once disengaging the interlocking state with the handle, when returning to its original state, the gears between the handle and turntable must be meshed back together, which is a hassle. It took a lot of time and also required adjustment.

Therefore, a crane game machine was devised (Utility Application No. 62-29219 filed by the present applicant) using a circular roller or friction wheel that is rotated by the operation of a handle and brought into contact with a turntable. According to this, when returning to the original state after the rotation transmission state between the turntable and the handle is released, meshing in the case of gears is not required, and maintenance, inspection, etc. are facilitated. In addition, when the handle is rotated rapidly, slippage occurs around the roller and the turntable is unable to follow the rotation of the roller, making it difficult to align the turntable, which has the effect of increasing the fun of the game. be.

[Means for Solving the Problems] The present invention is a further improvement of the structure in which the rollers interlocked with the handle come into contact with the turntable as described above, and in order to further improve the game playability, the rollers are partially removed. It is characterized in that it is configured so as to come into contact with the turntable.

[Function] In the crane game machine of the present invention, the turntable can be driven to rotate through the rollers by operating the handle, but since the rollers only partially contact the turntable, it is difficult to rotate the turntable according to the player's will. It won't be. Therefore, it becomes more difficult to align the turntable than in the case where the roller is always in contact with the turntable, and the game quality is improved. Additionally, when restoring the positional relationship between the turntable and rollers that have been previously released for maintenance or inspection, the work can be made easier by bringing them closer together without the rollers coming into contact with the turntable. Become.

[Embodiment] FIG. 1 is a perspective view showing the appearance of an embodiment of the present invention. The illustrated crane game machine has a housing 1 having a substantially prismatic shape, and transparent glass 2 is fitted into the front and left and right sides of the upper part of the housing 1 so that the inside can be seen. Inside the housing 1, a disc-shaped turntable 3 is installed at approximately the same height as the lower end of the glass part 2, and a large number of prizes 4 are placed on it. A crane 5 is suspended above the turntable 3, and four claws 6 extend downward from the crane 5. As will be described in detail later, the crane 5 is driven in the vertical direction by a drive mechanism housed in the upper part of the housing 1, and opens and closes the claw 6 in synchronization with the vertical movement.

Next, a portion of the front of the housing 1 located below the glass 2 is a door 7 that can be opened by rotating to the right as shown in FIG.
At the top of this door 7, there are two coin insertion slots 8 and 9, a start switch 10 as an operation unit operated by the player at the start of the game, and a handle 11 for manually rotating the turntable 3 as described later. are attached so that they can be operated from the outside. In this embodiment, the number of games that can be played with one coin insertion is two types: once and multiple times (for example, 4 times), and in order to allow the player to select one of them, as described above. Two coin insertion slots 8 and 9 are provided in the. When playing a game, when a predetermined number of coins are inserted into any of the insertion slots, the coin detection means provided inside is activated, and the game is started one by one.
Set the control unit of the game machine to perform the game once or multiple times. Further, in this game machine, a speaker 12 that generates a predetermined sound effect when the crane 5 is operated is installed below the start switch 10.

A knob 13 is attached to the center of the left end of the door 7, and when the knob 13 is turned with the door 7 closed, a pair of upper and lower clasps provided on the back side of the door 7 will open, as shown in FIG. 14 and 15 are activated so that the door can be locked or unlocked. Furthermore, door 7
A rectangular opening 16 is provided in the center of the door 7 to take out the prize held by the crane 5 as described later. It is blocked by Note that a handle 19 is provided on the outside of the cover plate 18.

As shown in FIG. 2, the prize receiving member 17 includes an opening cover plate 18 located at the front, fan-shaped side plates 20 and 21 extending perpendicularly to the rear of the door 7 from both left and right ends of the opening cover plate 18, and the cover plate 18. The left and right side plates are composed of a lower plate 22 that is inclined downward from the lower end and extends rearward along the lower ends of the left and right side plates 20 and 21, and a locking plate 23 that is curved in an arc downward from the rear edge. The corner portions 20 and 21 are attached rotatably in a direction perpendicular to the door 7 by a shaft pin 24 provided on the back surface of the door 7. In addition, arc-shaped notches 25 are formed in each of the left and right side plates 20 and 21, and a guide pin 26 protruding into the opening 16 of the door 7 is slidably fitted into each notch. , to act as a guide when the prize receiving member 17 rotates.

As shown in FIG. 2, the prize receiving member 17 described above usually has a downwardly extending tip portion of the locking plate 23 that is attached to the door 7.
By coming into contact with the back surface of the cover plate 18, the cover plate 18 is positioned inside the opening 16 to close it, and has the function of receiving and holding the prize 4 grasped by the crane 5 and discharged by the lower plate 22 as described later. .
In this state, when the handle 19 is pulled from the outside of the door 7, the prize receiving member 17 rotates and opens the opening 16, allowing the player to take out the prize. At this time, the rotation of the prize receiving member 17 stops when the tip of the locking plate 23 reaches the upper end of the opening 16 and comes into contact with the back surface of the door 7. That is,
The rotation range of the prize receiving member 17 is restricted by a locking plate 23.

Next, referring to FIGS. 2 and 3, handle 1
The means for rotating the turntable 3 when the turntable 1 is operated will be explained.

First, in the handle 11, a shaft 27, which is the center of rotation thereof, passes through the door 7, and a substantially oval roller 28 is fixed to the end of the shaft. The roller 28 is formed by fixing a crescent-shaped hard rubber plate to a disc, and the disc is fixed to the shaft 27. Therefore, when the handle 11 is rotated, the roller 28 will rotate eccentrically.

On the other hand, the turntable 3 is rotatably mounted on a base plate 31 that can be pulled out from inside the housing 1 toward the front (front side) when the door 7 is opened, and the base plate 3
1 has a part of the front edge cut out. When the board 31 with this turntable 3 attached is stored in the housing 1 and the door 7 is closed, the third
As shown in the figure, the roller 28 is located in the notch of the base plate 31 and close to the periphery of the bottom of the turntable 3, and when the handle 11 is rotated, the roller 28, which rotates eccentrically as described above, partially rotates. It is designed to come into contact with the bottom surface of the turntable 3.

Therefore, when the player rotates the handle 11, the turntable 3 can be rotated by frictional contact with the roller 28, but since the roller 28 is only in partial contact, the turntable 3 can be rotated according to the player's will. That is difficult. For example, even if the handle 11 is rotated in the opposite direction to change the rotation direction of the turntable 3, if the roller 28 is not in contact with the turntable 3, the turntable 3
There is a time lag until it begins to rotate in the opposite direction. This time difference is caused by the roller 28 turning on the turntable 3.
It is random because it depends on the time it takes to make contact with the object. This makes it difficult to align the turntable 3 with respect to the crane 5, which doubles the fun of the game.

Further, since only the roller 28 that partially contacts the turntable 3 is interposed between the handle 11 and the turntable 3, the interlocking state of the handle 11 and the turntable 3 can be changed simply by opening the door 7. In addition to being convenient for maintenance and inspection of the game machine, the roller 28 is prevented from coming into contact with the bottom of the turntable 3 when the door 7 is closed to restore the original state after the interlocking state has been released. This also provides the effect that the door 7 can be closed without resistance.

Furthermore, in this embodiment, as mentioned above, the door 7 is provided on the front of the housing 1, and the turntable 3 can be pulled out toward the front, which makes it easy to replenish prizes and maintain and inspect the inside of the game machine. There is also the advantage of becoming

The circular disk surface of the turntable 3 is provided with an opening 33 for discharging the prize 4 held by the claw 6 of the crane 5, and a corresponding opening 34 is also provided in the base plate 31. Further, in the housing 1, below the opening 34 of the base plate 31, a passage 35 is formed for guiding the prize 4 to the lower plate 22 of the aforementioned prize receiving member 17.

Next, the crane 5 as a prize capturing device and its drive mechanism will be explained.

First, the crane 5 includes a dome-shaped casing 41 in which four claws 6a, 6b, 6c, and 6d are housed, two each facing each other, so as to be openable and closable, as shown in FIGS. 4 to 6. This casing 41
A cylindrical part 42 is integrally formed on the top of the cylindrical part 42, and a pair of protrusions 43 and 44 each having a hole is provided at the upper end of the cylindrical part 42.
is provided. Then, the first chain 48
One end is connected to the casing 41. Further, a second chain 49 is connected to the upper end of a shaft member 50 that is housed in the casing 41 so as to be vertically movable. The lower end of this shaft member 50 protrudes in all directions, and the tips of protrusions extending substantially perpendicularly from the base ends of the claws 6a to 6d are rotatably connected to these protruding ends by shaft pins 51. Furthermore, each claw 6a
The proximal end portions of the rods 6d to 6d are each connected to one end of a connecting rod 53 by a shaft pin 52, and the other end of each connecting rod 53 is connected to the lower part of the cylindrical portion 42 of the casing by a shaft pin 54, respectively. In addition, the cylindrical part 4
The lower end of 2 protrudes downward within the casing 41.

The two chains 48 and 49 pass through a cylindrical portion 55 hanging from the internal ceiling of the housing 1 as shown in FIGS. 1 and 4, and pass through a drive mechanism 60 (see FIG. ) is connected to.

As shown in FIGS. 7 and 8, the drive mechanism 60 includes a power section 61 consisting of a motor and a transmission gear;
A link 63 whose one end is connected to the rotating output shaft 62
and a second link 65 which is connected in a substantially L shape by a connecting shaft 64 provided at the other end of this link 63, and the power unit 61 is attached to an inverted U-shaped mounting plate 66. is attached within the housing 1 by fixing it to the upper part of the housing 1 with bolts and nuts. The other end of the first chain 48, which has one end connected to the crane 5 as described above, is connected to the free end of the second link 65 by the second connecting shaft 67, while the two links 63 and The other end of the second chain 49 is connected to the first connecting shaft 64 which is connected to the connecting shaft 65 in a substantially L-shape.

In this embodiment, the drive mechanism 60 is installed so that the two links 63 and 65 can rotate in the horizontal direction, so the two chains 48 and 49 are rotated 90 degrees above the crane 5. A variable chain support section 70 is provided. This consists of two pulleys 71 and 72 around which chains 48 and 49 are wound, and a rectangular frame 75 that rotatably and horizontally supports shafts 73 and 74 of each pulley, respectively.

This chain support section 70 has two links 63
and 65 rotate in the vertical direction.
If 0 is placed, it can be omitted.
In this case, the power unit 61 and links 63 and 65 are
It is attached to a mounting plate that is fixed upright in the upper part of the housing 1.

Since the illustrated crane game machine is constructed as described above, its operation is as follows.

First, in the initial state, the drive mechanism 60 holds and suspends the crane 5 in the upper position as shown in FIG. 1 by pulling the first chain 48 as shown in FIG. second chain 49
is not pulled, so the shaft member 50 of the crane 5
is in the lowered position as shown in FIG. 5, with the claws 6 open. Here, when the player inserts a predetermined number of coins into either of the two coin insertion slots 8 and 9, the player can play the game a corresponding number of times.

Next, the player rotates the turntable 3 by turning the handle 11 so that a desired prize among the many prizes 4 placed on the top surface of the turntable comes directly under the crane 5. At this time,
As described above, the rotation of the handle 11 is transmitted to the turntable 3 via the partially abutting roller 28, so the turntable 3 cannot be rotated in accordance with the operation of the handle, which adds to the gameplay. Ru.

After positioning the turntable 3 by operating the handle as described above, the start switch 10 is then pressed.
As a result, the power section 61 of the drive mechanism 60 is activated and rotates the substantially L-shaped links 63 and 65 counterclockwise in FIG. 8. As a result, the first chain 48 suspending the crane 5 moves to the left, lowering the crane 5. The descent of the crane 5 is stopped when the first chain 48 stops moving to the left due to the rotation of the link 65. At this time, the crane 5 is in a position where the claw 6 can grasp the prize 4 on the turntable 3, and the approximately L-shaped links 63 and 65 are connected to the first chain 4.
By pulling the second chain 49 instead of the chain 8, the lengths of the chains and links and their positions are adjusted so that the shaft member 50 in the crane 5 is lifted and the claw 6 is closed, as shown in FIG. etc. are determined in advance. Closing of the claws 6 is performed by rotating the opposing claws in a direction toward each other as the shaft member 50 rises. As a result, when the prize 4 is successfully grasped by the claw 6, the prize 4
can be obtained.

When the claw 6 closes as described above, the crane 5 then begins to ascend. This is an L-shaped link 63
This is possible because the protruding lower end of the shaft member 50 lifted by the second chain 49 comes into contact with the lower end of the cylinder inside the casing 41 as the shaft member 65 rotates. The crane 5 is thus pulled up by the second chain 49 and returned to its initial upward position. When this position is reached, the L-shaped links 63 and 65 again tension the first chain 48 and suspend the crane 5, while
Since the second chain 49 is no longer tensioned, the shaft member 50 descends to open the claw 6. As a result, the prize held by the claw 6 (if any)
falls downward.

Therefore, if the crane 5 is able to grasp the prize 4 with its claws 6, the player can hold the handle 1 by the time the rising crane 5 reaches the upper position.
1 to rotate the turntable 3 so that its opening 33 is directly below the crane 5. This positioning is extremely difficult because the turntable 3 does not rotate as the handle is operated as described above, but if it is somehow possible, the claw 6
is opened, the prize 4 passes through the opening 33 of the turntable 3 and the opening 34 of the board 31 and enters the passage 35.
and is received by the prize receiving member 17.
Therefore, the player can pull the handle 19 to open the opening 16 of the door 7 and take out the prize as described above.

This is how one game ends,
If the number of games is 1 when inserting a coin, the drive mechanism 60 stops when the crane 5 returns to the raised position and opens the claw 6. On the other hand, if a plurality of games are selected, the crane 5 and the drive mechanism 60 repeat the above operations for the selected number of times.

Although the illustrated embodiment has been described above, the present invention is not limited thereto. For example, the crane serving as the prize capturing device and its drive mechanism are not limited to the structure shown in the drawings, but may be of any structure as long as the claws for gripping the prize can be positioned on the turntable and can be opened and closed.

[Effects of the invention] As described above, the present invention provides a crane game machine in which prizes are placed on a turntable. Since the rotational force is transmitted to the turntable, the turntable cannot be rotated as the handle is operated, making it difficult to position the turntable, thereby increasing the fun of the game. In addition, when restoring the positional relationship between the turntable and rollers that has been previously released for maintenance or inspection, the work can be made easier by allowing them to be brought closer to each other without the rollers coming into contact with the turntable. This effect can also be obtained.
