The present disclosure relates to the technical field of gaming equipment, and more specifically to a claw device for a crane machine and a crane machine.
In a capture game of catching or trapping a target, the game player needs to use a gripping claw to capture the game target. For different types of players, the claws should be designed to stimulate the interest of the players. In order to increase the challenge of the games, to stimulate the enthusiasm of adult gainers, the design of the claws should be aimed to achieve a relatively low success rate of the capture. Since child game players' operating ability is limited, in order to ensure that children can exercise hand and foot coordination and enjoy the fun in the games, the design of the claws should be aimed to achieve a relatively high success rate of the capture.
However, the existing claw design only meets the needs of adult gainers, and seldom considers the needs of child gainers. When the child game players use the claws designed for adult game players, the low success rate of the capture does not allow the child game players to obtain positive feedback in the games, which strikes the enthusiasm of the child game players to participate in the capture games. With the development of the crane machine market for children, the above problem is required to be mitigated or even solved.
In view of the above problems, the present disclosure proposes a claw device for a crane machine, aiming to solve the current technical problem of the low grasping success rate of the claw device affecting the game experience of the child game players.

The present disclosure proposes a claw device for a crane machine.
The claw device 100 includes an adjustment assembly 10 and an actuating assembly 20 movably connected to the adjustment assembly 10; the adjustment assembly 10 includes a fixed disk 11 and at least two connecting rods 12 spaced apart along an outer peripheral edge of the fixed disk 11; the actuating assembly 20 includes a pivot plate 21 disposed below the fixed disk 11 and at least two clamping rods 22 spaced apart along an outer peripheral edge of the pivot plate 21; a viewing window 23 is formed between adjacent two clamping rods 22; each clamping rod 22 includes a connecting segment 221, a fixed segment 222, and a holding segment 223 that are sequentially connected; the connecting segment 221 is movably connected to the pivot plate 21; the fixed segment 222 includes a first clamping surface 2221 toward a center axis of the pivot plate 21; the holding segment 223 extends toward the center axis of the pivot plate 21 from a lower end of the fixed segment 222; the holding segment 223 includes a first holding surface 2231 toward the center axis of the pivot plate 21; the first holding surface 2231 is connected to the first clamping surface 2221, and the first holding surface 2231 and the first clamping surface 2221 are arranged at an angle; an end of the connecting rod 12 is movably connected to the fixed disk 11, and the other end of the connecting rod 12 is movably connected to the connecting segment 221.
The claw device 100 refers to a component of the crane machine that can simulate an opening or closing action of a hand to grasp a subject (e.g., doll). The adjustment assembly 10 refers to a component of the claw device 100 that can drive other components to move to accomplish the opening or closing action. The actuating assembly 20 refers to a component of the claw device 100 that directly accomplishes the opening or closing action. The adjustment assembly 10 includes a fixed disk 11 and at least two connecting rods 12 spaced along an outer peripheral edge of the fixed disk 11; the number of the connecting rods 12 may be two, three, four, etc. The actuating assembly 20 includes a pivot plate 21 disposed below the fixed disk 11 and at least two clamping rods 22 spaced along an outer peripheral edge of the pivot plate 21. The number of the clamping rods 22 is set corresponding to the number of the connecting rods 12; the number of the clamping rods 22 may be two, three, four, etc.
A viewing window 23 is formed between each adjacent two clamping rods 22. Compared to a clamping member shaped like a bucket, the rod-shaped clamping member in the embodiments may facilitate the game player to observe the positional relationship between a target subject and a clamping portion 31, and thus assist the game player in adjusting the game strategy to improve the grasping success rate.
The clamping rod 22 includes a connecting segment 221, a fixed segment 222, and a holding segment 223 that are sequentially connected. The connecting segment 221 is movably connected to the pivot plate 21. An end of the connecting segment 221 is movably connected to the pivot plate 21, and the adjusting component 10 is configured to drive the connecting segment 221 to move by adjusting a height of the pivot plate 21; the other end of the connecting segment 221 is connected to the fixed segment 222. The fixed segment 222 includes a first clamping surface 2221 toward a center axis of the pivot plate 21; the holding segment 223 extends from a lower end of the fixed segment 222 toward the center axis of the pivot plate 21; the holding segment 223 includes a first holding surface 2231 toward the center axis of the pivot plate 21; the first holding surface 2231 is connected to the first clamping surface 2221, and the first holding surface 2231 and the first clamping surface 2221 are arranged at an angle. In some embodiments, the first holding surface 2231 is flat. In this way, when the target subject is being grasped, the first holding surface 2231 can uniformly provide a supporting force, such that the target subject will not fall down due to an unbalanced force during the movement of the claw device.
The angle between the first holding surface 2231 and the first clamping surface 2221 is greater than or equal to 90 degrees and less than or equal to 120 degrees. If the angle between the first holding surface 2231 and the first clamping surface 2221 is less than 90 degrees, the first holding surface 2231 can provide a limited support force to the target subject, making it difficult to secure the target subject in the claw device. If the angle between the first holding surface 2231 and the first clamping surface 2221 is greater than 120 degrees, the target subject is very likely to fall when the claw device 100 is moving. In the embodiments, however, the angle between the first holding surface 2231 and the first clamping surface 2221 is greater than or equal to 90 degrees and less than or equal to 120 degrees. When grasping the target subject, this angle may make the target subject be fixed in the claw device to prevent the claw device being failed in grasping; when the claw device is moving, this angle may ensure that the first holding surface 2231 can provide sufficient upward support force to prevent the target subject from falling.
An end of the connecting rod 12 is movably connected to the fixed disk 11, and the other end of the connecting rod 12 is movably connected to the connecting segment 221. The claw device 100 can cause the connecting rod 12 to move relative to the fixed disk 11 and the pivot plate 21 by adjusting a height difference between the fixed disk 11 and the pivot plate 21. Since the connecting rod 12 is movably connected to the connecting segment 221, the connecting rod 12 can drive the connecting segment 221 to move, which in turn causes the multiple clamping members to separate from each other or come close to each other, thereby accomplishing the simulated opening or closing action of the hand.
The present disclosure discloses a claw device 100 for a crane machine, including an adjustment assembly 10 and an actuating assembly 20; the adjustment assembly 10 includes a fixed disk 11 and connecting rods 12; the actuating assembly includes a pivot plate 21 and clamping rods 22; an viewing window 23 is formed between each adjacent two of the clamping rods 22; each clamping rod 22 includes a connecting segment 221, a fixed segment 222, and a holding segment 223 that are sequentially connected, where the connecting segment 221 is movably connected to the pivot plate 21, and the holding segment 223 extends towards a center axis of the pivot plate; a first holding surface 2231 of the holding segment 223 is connected to a first clamping surface 2221 of the fixed segment 222, and the first holding surface 2231 and the first clamping surface 2221 are arranged at an angle; an end of the connecting rod 12 is connected to the fixed disk 11, and the other end of the connecting rod 12 is connected to the connecting segment 221. In the present disclosure, the first clamping surface 2221 and the first holding surface 2231 are arranged at an angle to enable the target subject to be firmly grasped by the claw device without easily falling, and the viewing window 23 formed between adjacent clamping rods 22 facilitates the game player to observe the positional relationship between the target subject and the clamping rods 22 to adjust the game strategy, thereby improving the grasping success rate of the claw device.
Further, referring to
In the embodiments, the gradual increase in the width of the first holding surface 2231 along the extension direction of the holding segment 223 may increase the contact area between the first holding surface 2231 and the target subject, such that the target subject can be steadily grasped by the claw device. In other words, the increase in the contact area between the first holding surface 2231 and the target subject may facilitate the claw device to fix the target subject and further prevent the target subject from falling during the movement of the claw device.
Further, referring to
In the embodiments, the claw device 100 includes the pallet 30 detachably arranged on the fixed segment 222. The pallet 30 may be in a variety of shapes, such as triangle, circle, rectangle, and other regular and irregular shapes. The pallet 30 may be disposed both on an inner side and/or an outer side of the fixed segment 222. The pallet 30 may increase the contact area with the target subject, enabling the claw device to securely clamp the target subject. The pallet 30 is detachably arranged on the holding segment 223, which may facilitate parents to adjust the difficulty of the game by mounting or removing the pallet 30, such that the crane machine game can be adapted to child gamers of different ages.
The pallet 30 includes a clamping portion 31. The clamping portion 31 includes a second clamping surface 311 extending in a width direction of the first clamping surface 2221; the width of the second clamping surface 311 is greater than the width of the first clamping surface 2221. Compared to the first holding surface 2221, the second holding surface 311 increases the contact area with the target subject, thereby providing sufficient support and friction at the position of the fixed segment 222, such that the clamping rod 22 can clamp the target subject more securely.
Compared to the first holding surface 2231, the second holding surface 321 increases the contact area with the target subject, thereby providing more upward support force at the position of the holding segment 223, such that that the target subject may not be dislodged from the claw device easily.
A flat surface on the pallet that is back away from the second holding surface 321 is attached to the first holding surface 2231. In other words, the pallet 30 is arranged on the inner side of the fixed segment 222, rather than on the outer side of the fixed segment 222. When the pallet 30 is arranged on the outer side of the fixed segment 222, the fixed segment 222 is sandwiched between the target subject and the pallet 30. When the pallet 30 is arranged on the inner side of the fixed segment 222, the target subject is in direct contact with the pallet 30, i.e., there is no barrier between the target subject and the pallet 30. When the target subject is filled with cotton, the grasping success rate of the claw device is not greatly affected by whether the pallet 30 is arranged on the inner side or the outer side of the fixed segment 222. Currently, in order to increase the fun of the crane machine game, the target subject may further be a doll made of plastic or a doll arranged in a spherical mold, and the game player can directly grasp the spherical mold. When the pallet 30 is arranged on the outer side of the fixed segment 222, the fixed segment 222 clamped between the target subject and the pallet 30 may easily cause the doll to fall off, thereby reducing the success rate of grasping by the claw device. In the embodiments, the pallet 30 is arranged on the inner side of the fixed segment 222, and the pallet 30 can be in full contact with the target subject without obstruction, which may improve the grasping success rate of the claw device.
Further, referring to
In the embodiments, a partial region of the pallet 30 is raised to form a mounting seat 33, and the mounting seat 33 defines a mounting groove 331. In some embodiments, a central region of the pallet 30 is raised to form the mounting seat 33. Compared with other regions of the pallet 30 being raised to form the mounting seat 33, the central region of the pallet 30 being raised to form the mounting seat 33 may enable the pallet 30 to uniformly withstand the tension from the target subject, preventing the pallet 30 from rotating around the fixed segment 222 due to uneven force on the pallet 30. In addition, the central region of the pallet 30 being raised to form the mounting seat 33 makes the grasping stability of the claw device better, thereby improving the grasping success rate of the claw device, which is more suitable for a child gamer.
The inner diameter of the mounting groove 331 is gradually reduced along the length direction of the clamping rod 22, and the minimum inner diameter of the mounting groove 331 is less than or equal to the outer diameter of the fixed segment 222, which may facilitate the mounting of the fixed segment 222 to the mounting groove 331 from a position where the inner diameter of the mounting groove 331 is greater, and further enable the mounting groove 331 to have an interference fit with the fixed segment 222 at a position where the inner diameter of the mounting groove 331 is the least. Whether the fixed segment 222 can be stably assembled with the mounting groove 331 has a significant impact on the grasping success rate of the claw device. In the embodiments, the tapering of the inner diameter of the mounting groove 331 allows the mounting groove 331 and the fixed segment 222 to be securely assembled, which further improves the grasping success rate of the claw device.
In some embodiments, referring to
During mounting, a fixing rope 63 passes through the fixing hole 1121 to realize fixing, and an adjustment rope 64 passes through the first adjustment hole 1111 and the second adjustment hole 211 in turn to realize adjustment. It is to be understood that when the claw device 100 is in operation, the adjustment rope 64 and the fixing rope 63 cooperate with each other to realize the movement and grasping-releasing action of the claw device 100. In some embodiments, referring to
Further, referring to
Currently, conventional crane machines often have the phenomenon of the fixing rope 63 and the adjustment rope 64 becoming entangled with each other when in use. For this reason, the gamer usually operates a controller to cause the claw device 100 to shake vigorously, thereby causing the fixing rope 63 and the adjustment rope 64 to untangle from each other. However, the violent shaking may cause the fixing rope 63 or the adjustment rope 64 to detach from the fixed disk 11 or the pivot plate 21. In addition, in order to ensure that the adjustment rope 64 or the fixing rope 63 moves smoothly in the up-down direction, the aperture diameters of the fixing hole 1121, the first adjustment hole 1111, or the second adjustment hole 211 are provided large enough. Such apertures mean that the range of movement of the fixing rope 63 or the adjustment rope 64 is also wider. When the claw device 100 has a tendency to tilt or when tilting occurs, the offset of the fixing rope 63 or the adjustment rope 64 may contribute to the tilt or exacerbate the tilting effect.
In the embodiments, the lower end of the fixing rope 63 or the adjustment rope 64 can be arranged on the limiting column 50 from the mounting notch 52. The width of the mounting notch 52 is less than the aperture of the limiting hole 51, such that the fixing rope 63 or the adjustment rope 64 can be moved inside the limiting hole 51, but cannot be easily detached from the limiting column 50. In case of wear and tear of a part or damage of the part, the mounting notch 52 facilitates the adjustment rope 64 or the fixing rope 64 to be separated from the limiting column 50 for replacement.
In some embodiments, the limiting column 50 is arranged below the fixing hole 1121, and the limiting column 50 may either not be connected to the fixed disk 11 or may be connected to the fixed disk 11, such as bonded, threaded, snap-fit, and the like. The aperture of the limiting hole 51 is less than the aperture of the fixing hole 1121, for limiting the range of movement of the fixing rope 63 and reducing the effect of the offset of the fixing rope 63 on the overall tilt of the claw device 100. In some embodiments, the limiting column 50 is arranged below the second adjustment hole 211, and the limiting column 50 may either not be connected to the pivot plate 21 or may be connected to the pivot plate 21, such as bonded, threaded, snap-fit, and the like. The aperture of the second adjustment hole 211 is greater than the aperture of the limiting hole 51, for limiting the range of movement of the adjustment rope 64 and reducing the effect of the offset of the adjustment rope 64 on the overall tilt of the claw device 100. In some embodiments, the limiting column 50 is arranged below each of the fixing hole 1121 and the second adjustment hole 211.
Further, referring to
In the embodiments, the lower surface of the fixed disk 11 defines a first accommodation groove 61, a lower end of the fixing hole 1121 runs through the first accommodation groove 61, and the limiting column 50 is arranged in the first accommodation groove 61, i.e., the lower end of the fixing rope 63 can pass through the fixing hole 1121, the first accommodation groove 61, and the limiting column 50 in turn, and be connected to the limiting column 50. A sidewall surface of the first accommodation groove 61 abuts against an outer peripheral surface of the limiting column 50, such that the limiting column 50 can be hidden and fixed in the first accommodation groove 61. In this way, the overall structure of the claw device 100 is more compact. The mounting notch 52 closed or sealed on the sidewall surface of the first accommodation groove 61 prevents the fixing rope 63 from detaching from the limiting column 50 even when the claw device 100 is shaken violently.
The lower surface of the pivot plate 21 defines a second accommodation groove 62, a lower end of the second adjustment hole 211 runs through the second accommodation groove 62, and the second accommodation groove 62 is arranged with another limiting column 50, i.e., the lower end of the adjustment rope 64 can pass through the first adjustment hole 1111, the second adjustment hole 211, the second accommodation groove 62, and the limiting column 50 in turn and be connected to the limiting column 50. The sidewall surface of the second accommodation groove 62 abuts against an outer peripheral surface of the limiting column 50, such that the limiting column 50 can be hidden and fixed in the second accommodation groove 62. In this way, the overall structure of the claw device 100 is more compact. The mounting notch 52 closed or sealed on the sidewall surface of the second accommodation groove 62 prevents the fixing rope 63 from detaching from the limiting column 50 even when the claw device 100 is shaken violently.
In some embodiments, the fixing rope 63 includes a first rope body and multiple first limiting balls 65 fixed to the first rope body and sequentially distributed along a length direction of the first rope body. The first rope body enters into the limiting hole 51 from the mounting notch 52, and the aperture diameter of the limiting hole 51 is greater than the diameter of each first limiting ball 65, such that an upward movement of the first rope body may be limited.
The adjustment rope 64 includes a second rope body and multiple second limiting balls 66 fixed on the second rope body and sequentially distributed along a length direction of the second rope body. The second rope body enters into the limiting hole 51 from the mounting notch 52, and the aperture of the limiting hole 51 is greater than the diameter of each second limiting ball 66, such that an end of the second rope body may be limited from disengaging from the pivot plate.
In some embodiments, the fixed disk 11 is further arranged with a connecting channel 113 that connects the fixing hole 1121 and the first adjustment hole 1111, and the connecting channel 113 runs through the fixed disk 11 in the up-down direction.
During movement, the claw device 100 may sway due to inertia, causing the claw device 100 to be skewed. Or, although the claw device 100 grasps the target subject, the gravity center of the target subject is not on the center axis of the claw device 100, causing the claw device 100 to be skewed. The skewing of the claw device 100 may easily cause the target subject to fall, reducing the grasping success rate of the claw device 100. In the embodiments, when the claw device 100 is skewed, a rope 40 may be biased to an un-skewed side through the connecting channel 113 to keep the claw device 100 balanced, avoiding the target subject from falling due to the skewing of the claw device 100. Taking the skewing of the claw device 100 towards the side with the fixing hole 1121 as an example, the adjustment rope 64 may be slightly skewed towards the first adjustment hole 1111 through the connecting channel 113 to restore the balance.
In some embodiments, the pivot plate 21 is arranged with a counterweight member, and the gravity center of the counterweight member coincides with the gravity center of the pivot plate 21 in the up-down direction.
The clamping rod 22 is pivotally connected to both the pivot plate 21 and the connecting rod 12. When the clamping rods 22 are separated from each other, the clamping rods 22 are affected by friction, and the opening angle between neighboring clamping rods 22 cannot be achieved as desired. When encountering a target subject with a large size, the clamping rod 22 may not be able to grab the target subject due to the insufficient opening angle, thereby discouraging the game player. In the embodiments, the pivot plate 21 is arranged with a counterweight member, and the gravity center of the counterweight member coincides with the gravity center of the pivot plate 21 in the up-down direction, which uniformly increases the weight of the pivot plate 21. In this way, the pivot plate 21 is further separated from the fixed disk 11 by gravity, thereby allowing the clamping rods 22 to open at a greater angle. In some embodiments, an upper surface of the pivot plate 21 defines a third accommodative groove 67. The third accommodation groove 67 is arranged around the gravity center of the pivot plate 21, and the counterweight member is arranged within the third accommodation groove 67. In some embodiments, the second adjustment hole 211 is arranged at the gravity center of the pivot plate 21, the third accommodation groove 67 is arranged around the second adjustment hole 211, and the counterweight is arranged in the third accommodation groove 67. In this way, it is possible to make the opening angle of the clamping rods 22 greater, and at the same time make the structure of the claw device 100 more compact.

the actuating assembly 20 further includes two second tabs 24 disposed opposite each other on the connecting segment 221 and a second rotating shaft 25 connecting the two second tabs 24; the connecting rod 12 defines a second shaft hole 124 at an end near the connecting segment 221, and a second notch 125 is defined on an inner side of the connecting rod 12 corresponding to the second shaft hole 124; the second notch 125 is in communication with the second shaft hole 124; the second rotating shaft 25 is rotatably arranged in the second shaft hole 124 from the second notch 125.
Conventionally, in the pivoting structure, the rotating shaft is inserted into the shaft hole, and a locking member is arranged at an end of the rotating shaft. Due to the small size of the locking member, the mounting thereof usually requires external tools, which reduces assembly efficiency to some extent. In addition, during use, the locking member is prone to loosening. After the locking member is loosened, the connecting rod 12 is unable to drive the clamping rod 22 normally, resulting in a lower grasping success rate of the claw device. In the proposed embodiments, the first rotating shaft 14 and the second rotating shaft 25 realize the rotational connection with the fixed disk 11 and the connecting segment 221 from the first notch 122 and the second notch 125, respectively. The assembly process is efficient and convenient without the use of external tools. In addition, the first tab 13 and the second tab 24 prevent the first shaft hole 121 and the second shaft hole 124, respectively, from detaching from the rotating shaft. Further, the first tab 13 and the second tab 24 will not be loosened during use, such that the clamping rod 22 is enabled to work properly.
In some embodiments, referring to
Whether the claw device is balanced or not has a very important influence on the grasping success rate. Whether the mass of the clamping rod 22 and the connecting rod 12 is evenly distributed is crucial for the balance of the claw device. In some embodiments, the clamping rod 22 and/or the connecting rod 12 are made of plastic. Due to their certain thickness, the phenomenon of size shrinkage or hole shrinkage is likely to occur during manufacturing, resulting in uneven mass distribution of the clamping rod 22 and/or the connecting rod 12, which in turn affects the balance of the claw device. In the proposed embodiments, the hollowing out of the glue may be realized by defining grooves on the clamping rod 22 and/or the connecting rod 12 to avoid uneven mass distribution caused by the poor surface of the clamping rod 22 and/or the connecting rod 12, such that the balance of the claw device may not be affected.
The number of the second grooves 123 may be one, two or more. In some embodiments, the number of the second grooves 123 is three. The connecting rod 12 with three second grooves 123 may facilitate assembly by the visually impaired person. The visually impaired person can sense the number of the second grooves 123 by touching, so as to determine the position of the two ends of the connecting rod 12. In some embodiments, a side of the connecting rod 12 has a first notch 122. The visually impaired person can sense the number of the second notches 123 by touch and determine the position of the connecting rod 12 that he or she is holding relative to the position of the first notch. In this way, it is convenient for the visually impaired person to quickly mount the second rotating shaft 25 from the first notch 122 to the first shaft hole 121.
