Description

Technical Field

[0001] The present invention relates to a crane game machine that operates a catcher to grab a prize.

Background Art

[0002] A crane game machine is a facility that provides a game in which a player can obtain a play right by inserting a coin, operate the catcher to reach a desired position in a showcase with this play right, attempt to grab a prize placed in the showcase, and if the player can lift the prize and discharge it from the discharge port, the player can acquire the commodity.

[0003] Hereinafter, the configuration of a conventional crane game machine will be described with reference to FIG. 1. Here, FIG. 1 is a side view showing the configuration of a conventional crane game machine 1.

[0004] As shown in FIG. 1, a conventional crane game machine 1 includes a housing 10 that defines an inner space 100 for accommodating a plurality of prizes, a catcher mechanism 11 disposed in the inner space 100 for grabbing a prize, and an operation interface 12 connected to the housing 10 for operating the movement and operation of the catcher mechanism 11. Here, the prizes accommodated in the inner space 100 of the housing 10 are not limited and may be various types of articles (i.e., articles with various appearances, weights, densities, etc.).

[0005] On the premise that the catcher mechanism 11 is set so as to be able to surely grab a prize, in order to obtain a balance between the customer attraction effect and profit acquisition, after determining the prize to be placed in the inner space 100, the owner / manager of the crane game machine 1 not only adjusts the specifications of the catcher mechanism 11 but also makes appropriate settings for parameters such as the gripping force, movement sensitivity, lowering speed, and rising speed of the catcher mechanism 11 according to the actual state of the prize.

[0006] Furthermore, in recent years, the market related to crane games has become increasingly competitive, so it is common practice to frequently change the prizes in response to market demand. [Prior art documents] [Patent Documents]

[0007] [Patent Document 1] Japanese Patent Publication No. 2023-138754 [Overview of the project] [Problems that the invention aims to solve]

[0008] However, conventional crane game machines have a problem in that when it comes to exchanging prizes for other types of prizes with different weights, it is time-consuming to determine the size and gripping force specifications of the catcher mechanism and then replace the catcher mechanism.

[0009] Furthermore, adjusting the descent and ascent speeds of the catcher mechanism according to the weight of the prize affects the descent and ascent movements of the catcher mechanism, and consequently, the visual appearance when the catcher mechanism throws and drops the prize. These are important factors that influence a player's motivation to play.

[0010] Furthermore, if the descent and ascent speeds of the catcher mechanism can only be set to fixed values, even if the specifications of the catcher mechanism are applied to the weight of the prize, it will be difficult to make the catcher mechanism perform specific actions according to the weight of the prize. For this reason, when exchanging prizes for other types of prizes with different weights, the crane game machine owner / manager may not be able to maintain a balance between attracting customers and generating profits.

[0011] Therefore, in terms of adjustment capabilities, conventional crane game machines cannot meet the need to handle prizes with a wide range of weights. For this reason, there is room for improvement in the design of conventional crane game machines.

[0012] Therefore, in view of the above problems, the present invention aims to provide a crane game machine that can solve at least one of the above-mentioned drawbacks. [Means for solving the problem]

[0013] To achieve the above objective, the present invention comprises a housing, an operating unit, and a control unit. The aforementioned enclosure has a designated storage space inside for accommodating prizes. The aforementioned operating unit is located within the aforementioned storage space and comprises a crane mechanism, a catcher mechanism, and a motor. The crane mechanism is provided at the top of the storage space, The catcher mechanism is provided on the crane mechanism so that it can be moved by the crane mechanism, and is configured to be able to grab the prize. The motor is connected to the catcher mechanism and is configured to perform a downward movement, moving the catcher mechanism downward, and an upward movement, moving the catcher mechanism upward after the downward movement has been performed. At least one of the aforementioned downward movement and the aforementioned upward movement has multiple sections, The speed at which the catcher mechanism moves in one of the plurality of sections is different from the speed at which the catcher mechanism moves in at least one of the other plurality of sections. The control unit is signal-connected to the operation unit and includes an operation interface and a setting interface. The operating interface can control the movement of the catcher mechanism by the crane mechanism and transmit commands related to the downward movement to the motor so that the motor begins to drive the downward movement of the catcher mechanism. The setting interface is signal-connected to the motor and is configured to be able to set the moving speed of the catcher mechanism in each of at least one of the downward movement and the upward movement, and a crane game machine is provided, characterized in that.

Effect of the Invention

[0014] According to the crane game machine according to the present invention, by operating so that the setting interface of the control unit is signal-connected to the motor and the moving speed of the catcher mechanism is set via the motor, it can be applied to grab various types of prizes.

[0015] In addition, since the movement when the catcher mechanism grabs a prize can be set, one prize held by the catcher mechanism can be more easily thrown into the discharge opening of the housing. In this way, the player's interest can be enhanced, and the ability to attract customers can be effectively improved.

Embodiments for Carrying Out the Invention

[0017] Hereinafter, the crane game machine according to the present invention will be described with reference to the drawings.

[0018] Referring to FIGS. 2 to 4, the configuration of an embodiment of the crane game machine according to the present invention will be described. Here, FIG. 2 is a schematic diagram showing the configuration of the crane game machine according to an embodiment of the present invention, FIG. 3 is a partial side view showing the configuration of the operation unit 3 according to this embodiment, and FIG. 4 is a perspective view showing the configuration of the position limiting portion 324 of the catcher mechanism 32 according to this embodiment.

[0019] The crane game machine according to an embodiment of the present invention is applied to the grasping of prizes within a wide weight range, and as shown in FIG. 2, includes a housing 2, an operation unit 3, and a control unit 4.

[0020] As shown in FIG. 2, an accommodation space 200 for accommodating prizes is defined inside the housing 2. The operation unit 3 is disposed within the accommodation space 200 and is for grasping the prizes accommodated within the accommodation space 200. The control unit 4 is electrically connected to the operation unit 3 and is for controlling the movement of the operation unit 3.

[0021] Here, the housing 2 and the operation unit 3 are physical mechanisms, and the control unit 4 is a combination of hardware and software (for example, firmware) for performing control, operation, adjustment, setting, etc. on the operation unit 3.

[0022] The enclosure 2, as shown in Figure 2, comprises a bottom plate 21 and surrounding walls 22. The surrounding walls 22 extend upward from the periphery of the bottom plate 21 and together with the bottom plate 21 define the storage space 200. The owner / manager of the crane game machine can freely place various types of prizes (for example, prizes of different types such as price, size, shape, and weight) in the storage space 200.

[0023] Here, the more specific configurations and arrangements of the enclosure 2, which serves as the casing for the crane game machine, such as discharge openings, shielding plates, and window switches, are not important features of the present invention. Therefore, it is assumed that fellow professionals can understand the content of the present invention without further detailed descriptions of these features.

[0024] As shown in Figures 2 to 4, the operating unit 3 comprises a crane mechanism 31, a catcher mechanism 32, and a motor 33 (see Figure 3).

[0025] As shown in Figure 2, the crane mechanism 31 is located at the top of the storage space 200 and is used for the horizontal movement of the catcher mechanism 32, which will be described later.

[0026] As shown in Figures 2 and 3, the catcher mechanism 32 is provided on the crane mechanism 31 so that it can be moved by the crane mechanism 31, and is configured to be able to grab prizes placed in the storage space 200.

[0027] The initial position of the catcher mechanism 32 is a predetermined distance from the bottom plate 21 of the housing 2. This predetermined distance is determined by the relevant conditions and requirements to be set (for example, the size of the prize).

[0028] As shown in Figures 2 and 3, the catcher mechanism 32 comprises a main body 321, a tow rope 322, a claw portion 323, and a position limiting portion 324. One end of the tow rope 322 is connected to the motor 33. The claw portion 323 is connected to the other end of the tow rope 322 and is used to grab prizes. The position limiting portion 324 is located below the main body 321 and is positioned between the main body 321 and the claw portion 323.

[0029] As shown in Figure 4, the position limiting portion 324 has a through hole 327 through which the traction rope 322 passes, and a contact surface 328 that faces downward and is inclined with respect to a hypothetical horizontal plane (not shown).

[0030] Here, the position limiting section 324 has the function of preventing the claw portion 323 from directly hitting the main body portion 321. As a result, when the claw portion 323 moves upward, even if the motor 33, which will be described later, does not stop the upward movement of the catcher mechanism 32 at an appropriate time, the claw portion 323 will only collide with the contact surface 328 of the position limiting section 324 and will not collide with the main body portion 321.

[0031] The position limiting unit 324 is replaceable. This configuration improves the service life of the crane game machine in this embodiment.

[0032] As shown in Figure 3, the motor 33 is connected to one end of the traction rope 322 of the catcher mechanism 32 as described above, and is configured to perform a descent stroke in which the catcher mechanism 32 moves downward, and an ascending stroke in which the catcher mechanism 32 moves upward after the descent stroke has been performed.

[0033] Specifically, the descent phase is when the towing rope 322 of the catcher mechanism 32 is rewound down and the claw portion 323 descends, while the ascent phase is when the towing rope 322 of the catcher mechanism 32 is rewound up and the claw portion 323 rises.

[0034] The motor 33 operates at a predetermined rotational speed to wind up or wind down the towing rope 322 connected to the claw portion 323, thereby moving the catcher mechanism 32 at a travel speed corresponding to the rotational speed.

[0035] There is a positive correlation between the rotational speed and the torque of the motor 33; the faster the motor 33 retracts the tow rope 322, the faster the claw portion 323 moves upward. Also, when the claw portion 323 is gripping a prize, the faster the rotational speed of the motor 33, the greater the force with which the claw portion 323 pulls the prize.

[0036] As shown in Figure 2, the control unit 4 includes an operation interface 41, a setting interface 42, and an adjustment interface 43.

[0037] The operating interface 41 controls the movement of the catcher mechanism 32 by the crane mechanism 31 and also transmits commands related to the descent to the motor 33, causing the motor 33 to start driving the descent of the catcher mechanism 32. The operating interface 41 can also transmit commands related to grasping to the catcher mechanism 32, causing the claw portion 323 of the catcher mechanism 32 to approach the prize and perform the grasping action, and then drive the upward movement of the catcher mechanism 32.

[0038] The setting interface 42 is signal-connected to the motor 33 (for example, connected in a way that allows communication via electrical signals) and is configured to allow setting the movement speed of the catcher mechanism 32.

[0039] The adjustment interface 43 is configured to allow operation to adjust the gripping force of the catcher mechanism 32 during the upward stroke of the catcher mechanism 32.

[0040] During the downward movement of the catcher mechanism 32, when a player of the crane game machine of this embodiment operates the control interface 41 of the control unit 4 and the control interface 41 transmits a command related to grabbing to the catcher mechanism 32, the claw portion 323 of the catcher mechanism 32 approaches the prize, and after the claw portion 323 has approached the prize, the upward movement (i.e., the claw portion 323 rises) is performed.

[0041] On the other hand, if no command related to grabbing according to the player's operation is transmitted from the operation interface 41 to the catcher mechanism 32 during the downward stroke of the catcher mechanism 32, the catcher mechanism 32 will close the claw portion 323 by the gripping force when one of the following three conditions is met, and after the claw portion 323 has closed, the upward stroke (i.e., the claw portion 323 rising) will be performed.

[0042] Here, the three conditions mentioned above are that the claw portion 323 has descended by a specific distance, that the claw portion 323 has come into contact with one of the prizes, and that the claw portion 323 has come into contact with the bottom plate 21 of the housing 2.

[0043] The actual operation of the crane game machine of this embodiment will be described below, using the upward movement of the catcher mechanism 32 as an example.

[0044] The upward movement of the catcher mechanism 32 is divided into multiple sections arranged in chronological order, in which the speed of movement can change. Furthermore, the upward movement is divided into multiple stages arranged in chronological order, in which the gripping force can change.

[0045] In other words, for multiple sections, the movement speed of the catcher mechanism 32 in one of the multiple sections is different from the movement speed of the catcher mechanism 32 in at least one of the other sections.

[0046] Furthermore, for multiple stages, the gripping force of the catcher mechanism 32 in one of the stages is different from the gripping force of the catcher mechanism 32 in at least one other of the stages.

[0047] The setting interface 42 is signal-connected to the motor 33, allowing the movement speed of the catcher mechanism 32 in each of the multiple sections of the ascent to be set according to the predetermined distance described above.

[0048] Here, the moving speed of the catcher mechanism 32 in each section of the ascent is the average speed of the catcher mechanism 32 in each section of the ascent.

[0049] The following describes how the catcher mechanism 32 according to this embodiment grasps a relatively heavy prize and moves it upward, with reference to Figures 2, 3, and 5.

[0050] Here, Figure 5 is a diagram showing the relationship between speed and time when the catcher mechanism 32 according to this embodiment grasps a relatively heavy prize and moves upward. In Figure 5, the vertical axis represents the rotational speed of the motor 33, i.e., the movement speed of the catcher mechanism 32 (movement speed of the claw portion 323), while the horizontal axis represents the time of the upward movement.

[0051] The magnitude of the gripping force of the catcher mechanism 32 is a requirement that determines whether the claw portion 323 can reliably grip a relatively heavy prize at the moment the claw portion 323 closes. Therefore, if the gripping force of the catcher mechanism 32 is set sufficiently in the first stage of the upward movement, it can reliably grip that relatively heavy prize.

[0052] Let's explain using the example that the upward movement has two sections (see the horizontal axis in Figure 5). Here, if the movement speed of the catcher mechanism 32 is too fast at the beginning of the upward movement of the catcher mechanism 32, there is a risk that the relatively heavy prize being held will fall from the claw portion 323 of the catcher mechanism 32.

[0053] To prevent this situation, the speed at which the catcher mechanism 32 moves in the first section of the ascent is set to be slower than the speed at which the catcher mechanism 32 moves in the second section; that is, the catcher mechanism 32 is set to move slower in one of the multiple sections than in another section that follows that first section.

[0054] Therefore, if the torque of the motor 33 increases in the later section (i.e., the second section), causing the catcher mechanism 32 to move faster in the later section, the likelihood of the relatively heavy prize being grasped by the catcher mechanism 32 and moved to the catcher mechanism 32's initial position increases.

[0055] Generally, the gripping force of the catcher mechanism 32 in the first stage of the upward movement is adjusted to be sufficient for the weight of the prize. However, in practice, the number of stages and the number of intervals in the upward movement can differ. For example, one interval may occupy the same period as two consecutive stages, or three consecutive intervals may occupy the same period as two consecutive stages. This allows for effects such as shaking and dropping the grabbed prize during the upward movement, or ensuring that the prize remains held. Hereinafter, the setting of the gripping force of the catcher mechanism 32 in each stage of the upward movement is not limited to the above.

[0056] The following describes how the catcher mechanism 32 according to this embodiment grasps a relatively light prize and moves it upward, with reference to Figures 2, 3, and 6.

[0057] Here, Figure 6 is a diagram showing the relationship between speed and time when the catcher mechanism 32 according to this embodiment grasps a relatively light prize and moves upward. In Figure 6, as in Figure 5, the vertical axis represents the rotational speed of the motor 33, i.e., the movement speed of the catcher mechanism 32 (movement speed of the claw portion 323), while the horizontal axis represents the time of the upward movement.

[0058] If the prize is relatively light, there is a low probability that the relatively light prize will fall from the claw portion 323 of the catcher mechanism 32 at the beginning of the upward stroke of the catcher mechanism 32. Therefore, as shown in Figure 6, if there are two sections in the upward stroke, the speed of the catcher mechanism 32 in the first section of the upward stroke is set to be faster than the speed of the catcher mechanism 32 in the second section, that is, the catcher mechanism 32 can move faster in one of the multiple sections than in another section that follows that one. This prevents the claw portion 323 from rising too rapidly and colliding with the position limiting portion 324.

[0059] Furthermore, if the prize being held is relatively light, there is a relatively high possibility that the prize will be thrown by the movement of the claw portion 323. To prevent this situation, the claw portion 323 is set so that it does not rise rapidly in the later section (i.e., the second section).

[0060] The following describes how the setting interface 42 of the control unit 4 according to this embodiment adjusts the movement speed of the catcher mechanism 32 according to a predetermined distance between the initial position of the catcher mechanism 32 and the bottom plate 21, with reference to Figures 2, 3, and 7.

[0061] Here, Figure 7 is a schematic diagram showing the state in which the setting interface 42 of the control unit 4 according to this embodiment adjusts the movement speed of the catcher mechanism 32 according to a predetermined distance between the initial position of the catcher mechanism 32 and the bottom plate 21.

[0062] After a prize is grasped by the catcher mechanism 32, it needs to be lifted by the catcher mechanism 32 a predetermined distance. Therefore, in addition to setting the appropriate movement speed and gripping force of the catcher mechanism 32 according to the weight of the prize, the setting interface 42 of the control unit 4 can further set the movement speed of the catcher mechanism 32 in each section of the lifting stroke according to the predetermined distance mentioned above.

[0063] Here, the predetermined distance mentioned above is the distance between the initial position of the catcher mechanism 32 and the bottom plate 21 of the housing 2. This predetermined distance is also the distance the catcher mechanism 32 moves during the downward stroke and the distance the catcher mechanism 32 moves during the upward stroke.

[0064] The owner / manager of the crane game machine may consider that the player may be able to use special techniques to win prizes by operating the control interface 41 to swing or rotate the traction rope 322 and claw portion 323 of the catcher mechanism 32, thereby throwing the prize grabbed by the catcher mechanism 32 into the discharge opening of the cabinet 2.

[0065] In this case, in addition to appropriately setting the gripping force of the catcher mechanism 32 at different stages, the owner / manager of the crane game machine can further set the movement speed of the catcher mechanism 32 corresponding to each section in the upward movement according to a predetermined distance and the weight of the prize, via the setting interface 42.

[0066] In this way, when the catcher mechanism 32 grasps a prize that is within a specific weight range specified by the owner / manager, the traction rope 322 and the claw portion 323 can be made to swing with a specific degree of swing (i.e., swing angle and height) and a specific number of times during the upward movement of the catcher mechanism 32.

[0067] For example, if the predetermined distance is 1 meter and the movement speed of the catcher mechanism 32 is set to 25 centimeters per second, when the claw portion 323 is pulled upward from the bottom plate 21 of the housing 2 and moved in a straight line, the claw portion 323 returns to its initial position in 4 seconds, meaning that the upward movement of the catcher mechanism 32 takes 4 seconds.

[0068] In this case, when the claw portion 323 grasps a prize, the degree of oscillation of the tow rope 322 and the claw portion 323 corresponding to the weight of the prize can be set according to the torque of the motor 33 corresponding to the movement speed of the catcher mechanism 32 (i.e., 25 centimeters per second).

[0069] Based on this, by performing further calculations and fine adjustments to the movement speed of the catcher mechanism 32, it is possible to set it so that when the catcher mechanism 32 grabs a prize and the player swings or rotates the traction rope 322 and the claw part 323, the claw part 323 swings twice before returning to its initial position.

[0070] By adjusting the movement speed of the catcher mechanism 32 in each section of the upward movement, the movement of the claw portion 323 can be changed, so that the crane game machine of this embodiment can be applied to grab various types of prizes (e.g., prizes of different weights). In this way, players can enjoy the specific movements of the claw portion 323. As a result, according to the above-described settings, the objective of attracting advanced players who try to play the crane game machine of this embodiment using the special techniques described above can be achieved.

[0071] It should be noted that, although the upward stroke of the catcher mechanism 32 was described as an example in this embodiment, the invention is not limited thereto, and in other embodiments, the downward stroke of the catcher mechanism 32 may be configured to have multiple sections. In this case, the setting interface 42 can set the movement speed of the catcher mechanism 32 in each of the multiple sections of the downward stroke. Thus, the crane game machine of this embodiment can be applied to grab a wider variety of prizes (e.g., prizes of different sizes).

[0072] In summary, according to the crane game machine of the present invention, the setting interface 42 of the control unit 4 is signal-connected to the motor 33 and operated to set the movement speed of the catcher mechanism 32 via the motor 33, and the adjustment interface 43 can be operated to adjust the gripping force of the catcher mechanism 32. By coordinating the gripping force of the catcher mechanism 32 with the torque of the motor 33, the crane game machine of the present invention can be applied to grab various types of prizes (for example, prizes of different weights and sizes).

[0073] Furthermore, the movement of the catcher mechanism 32 when it grasps a prize can be adjusted. For example, by adjusting the speed of movement of the catcher mechanism 32 in each section of the upward movement, it is possible to make it easier for one of the prizes being grasped by the catcher mechanism 32 to be thrown into the discharge opening of the housing 2. In this way, the crane game machine according to the present invention can enhance the player's enjoyment and effectively improve the ability to attract customers.

[0074] In the above, many specific details have been provided to facilitate an overall understanding of the present invention. However, it will be apparent to those skilled in the art that one or more other embodiments can be implemented without providing specific details.

[0075] While preferred embodiments and variations of the present invention have been described above, the present invention is not limited thereto, and all modifications and equivalent configurations are included as part of the spirit and scope of the broadest interpretation. [Industrial applicability]

[0076] According to the present invention, it is possible to provide a crane game machine that can enhance player interest and effectively increase the ability to attract customers. Therefore, it has potential for industrial application. [Explanation of Symbols]
