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. In such game machines, the time or number of times a game can be played by inserting a coin once is predetermined.

[Problems to be solved by the invention] However, in such conventional crane game machines, the crane can move in two directions, vertically and horizontally, in order to move to any position on the prize placement surface represented by two-dimensional coordinates. It is necessary to be driven by Therefore, the structure of the drive mechanism is complicated and expensive, and it takes time and effort to assemble and repair.

On the other hand, crane game machines are also known in which a turntable is installed in the housing and a large number of prizes are placed on the turntable. In this case, the player can set the crane at any position on the turntable by rotating the turntable horizontally using a handle, and the structure is simpler than the above-mentioned game machines. .

However, in this crane game machine as well, it is necessary to move the crane and open and close the claw, which makes the structure of the crane and its drive groove complicated.

Therefore, an object of the present invention is to realize the functions necessary as a prize capturing device in a crane game machine having a structure in which prizes are placed on a turntable using a simple crane and its drive mechanism.

[Means for Solving the Problems] The present invention includes a turntable that is horizontally rotatably arranged in a housing and on which a prize is placed, a claw that grips the prize, and a claw that is positioned on the turntable. The prize capturing device includes a prize capturing device including a drive mechanism to be set, and an operation unit that operates the prize capturing device in response to an activation operation by an operator, and the claw is caused to grasp the prize by closing the claw on the turntable. In the crane game machine, the claw is connected to two relatively movable support members, and is configured to open and close when one of the support members moves relative to the other. The drive mechanism of the prize capturing device is composed of two arms each having one end connected to each of the two supporting members via a hanging means such as a chain, and the other end of each arm is formed into a substantially L-shape. When the two support members move relative to each other via the hanging means, the claws are opened and closed by rotating the link to open and close the two support members. It is characterized by comprising a rotary drive means that moves the claws up and down when the members move up and down together.

[Operation] According to the above configuration, when the operator performs the activation operation, the rotation drive means of the prize capturing device rotates the two arms. Since these arms form a substantially L-shaped link, a rotational shift corresponding to the substantially L-shape occurs between the two rotating arms. The rotation of each arm causes the claws to open and close when the two support members move relative to each other via the hanging means connected to one end of each arm, and to open and close the claws when the two support members move up and down together. Move up and down. This accomplishes the prize capturing operation on the turntable.

[Example] The following description will be made with reference to the accompanying drawings.

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's 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, 21, and a locking plate 23 that is curved downward in an arc shape 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, arcuate 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, the handle 11 is
A shaft 27 serving as the center of rotation passes through the door 7, and a friction wheel consisting of a roller 28 made of a material with high friction such as rubber is fixed to the end of the shaft. 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. Part of the edge is cut out. When the board 31 to which the turntable 3 is attached is housed in the housing 1 and the door 7 is closed, the roller 2 that rotates together with the handle 11 as shown in FIG.
8 is located in the notch of the substrate 31 and comes into contact with the peripheral edge of the bottom surface of the turntable 3. Therefore, when the handle 11 is rotated, the turntable 3 rotates due to friction with the roller 28, but the handle 11
If the roller 28 is rotated rapidly, slippage will occur around the roller 28, and the turntable 3 will not be able to follow the rotation of the roller 28. Therefore, it becomes difficult to align the turntable 3 with respect to the crane 5, making the game more interesting.

Note that an opening 33 is provided in the circular disk surface of the turntable 3 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. Also,
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 prize receiving member 17 described above.

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 is connected through the rings 45 and 46 passed through the holes of each protrusion and another ring 47 passed through these rings.
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 ends 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 cylindrical portion 42 and shaft member 50 described above serve as supporting members for the claws 6a to 6c, respectively.

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 first arm 63 whose one end is connected to the rotation output shaft 62, and a second arm 65 which is connected to form a substantially L-shaped link by a connecting shaft 64 provided at the other end of this arm 63. The power unit 61 is mounted in the housing 1 by attaching it to an inverted U-shaped mounting plate 66 and 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 arm 65 via the second connecting shaft 67, while the two arms 63 and The other end of the second chain 49 is connected to the first connecting shaft 64 which is connected to the connecting shafts 65 in a substantially L-shape.

In this embodiment, the drive mechanism 60 is attached so that the link consisting of the two arms 63 and 65 can rotate in the horizontal direction, so that the two chains 48 and 49 are connected above the crane 5. A chain support section 70 is provided that changes the angle by 90 degrees. This consists of two pulleys 71 and 72 around which chains 48 and 49 are wound, and a shaft 73 of each pulley.
and 74, respectively, and a rectangular frame 75 which rotatably and horizontally supports them.

On the other hand, as shown in FIG. 9, when the drive mechanism 60 is arranged so that the link consisting of two arms 63 and 65 rotates in the vertical direction, the chain support section 70 may be omitted. can.
In this case, the power unit 61 and the link are connected to the housing 1
It is attached to a mounting plate 76 that is fixed upright in the upper part of the interior.

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,
The rotation of the handle 11 is transmitted to the turntable 3 via the roller 28, which is a friction wheel, so if the handle 11 is rotated rapidly or stopped suddenly, the roller 28 slips and the turntable 3 is rotated.
It becomes difficult to rotate the handle as per the handle operation, which increases the fun of the game.

After the above-mentioned positioning of the turntable 3 is completed by operating the handle, the start switch 10 is then pressed. In this way, the power section 61 of the drive mechanism 60 is activated, and the approximately L consisting of two arms 63 and 65 is activated.
Rotate the letter-shaped link counterclockwise in FIG. As a result, the first chain 48 suspending the crane 5 moves to the left, and the crane 5
lower. The descent of the crane 5 is stopped when the first chain 48 stops moving to the left due to the rotation of the arm 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 link is pulling the second chain 49 instead of the first chain 48. Accordingly, the lengths of the chains and arms, their positions, etc. are determined in advance so that the shaft member 50 within the crane 5 is lifted and the claw 6 is closed, as shown in FIG. The claw 6 is closed by the shaft member 5.
This is done by rotating the opposing claws toward each other as the number 0 rises. As a result, if the prize 4 is successfully grasped by the claws 6, the prize 4 can be acquired.

When the claw 6 closes as described above, the crane 5 then begins to ascend. 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 substantially L-shaped link 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 approximately L-shaped link again applies tension to the first chain 48 and suspends the crane 5, while the second chain 49 is not pulled, so the shaft The member 50 descends to open the claw 6. As a result, the prize (if any) held by the claw 6 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. If this is done successfully, the claw 6 opens, and the prize 4 falls into the passage 35 through the opening 33 of the turntable 3 and the opening 34 of the base plate 31, 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 hanging means for connecting a crane with claws and its drive mechanism is not limited to a chain, but can also be a rope or other rigging.

[Effects of the invention] As described above, the present invention provides a crane game machine in which the prize is placed on a turntable, in which the claw that grips the prize is connected to two relatively movable support members. The drive mechanism of the prize capturing device is configured to open and close by moving one of the supporting members relative to the other.
A link formed by two arms each having one end connected to each of the two supporting members via a hanging means such as a chain, and the other end of each arm being joined to form a substantially L-shape. and a rotational drive that opens and closes the claws when the two support members move relative to each other via the hanging means by rotating the link, and moves the claws up and down when the two support members move up and down together. Since it is simply constructed with the means, it has the necessary functions as a prize capturing device, and has the effect that the game machine can be easily assembled and repaired at low cost.
