Abstract
Description
Technical Field
[0001] This application relates to the field of stress-relieving toys, and more particularly to a stress-relieving toy. Background Technology
[0002] With the accelerating pace of society and increasing life pressures, stress-relieving toys have gradually gained widespread attention and popularity. By providing tactile stimulation, repetitive actions, or sensory feedback, stress-relieving toys can help users alleviate anxiety, shift attention, and release stress to some extent, making them suitable for various groups such as students and office workers.
[0003] As a typical stress-relieving toy, the fidget spinner has a relatively simple structure, mainly consisting of the spinner body, a central bearing, and a grip cap. Some products also have counterweights or decorative modules. Users can hold the spinner at both ends with their fingers and spin the body to make it rotate around the central bearing. The visual effects and inertial feedback generated during the rotation can bring a relaxing and focused experience.
[0004] However, existing fidget spinner products are mostly based on a single rotating structure, lacking more interactive layers and operation methods. Prolonged use can easily lead to aesthetic fatigue, thus diminishing the stress-relieving effect. Therefore, improving the playability of fidget spinners has become an urgent problem to be solved. Utility Model Content
[0005] In view of this, it is necessary to provide a more durable and diverse stress-relieving toy to solve the above problems.

[0009] A sliding component is disposed within the inner cavity and is slidably connected to the rotating component;
[0010] The direction perpendicular to the axis of the grip is referred to as the first direction. When the rotating component rotates around the grip, the sliding component slides along the first direction under centrifugal force to partially extend or retract into the inner cavity.

[0039] An embodiment of this application provides a decompression toy, comprising:
[0040] Finger grip;
[0041] The rotating assembly includes a first rotating component and a second rotating component that overlap each other. Both the first rotating component and the second rotating component are sleeved on the grip and rotatably connected to the grip. The first rotating component and the second rotating component enclose an inner cavity.
[0042] A sliding component is disposed within the inner cavity and is slidably connected to the rotating component;
[0043] The direction perpendicular to the axis of the grip is referred to as the first direction. When the rotating component rotates around the grip, the sliding component slides along the first direction under centrifugal force to partially extend or retract into the inner cavity.
[0044] The aforementioned stress-relief toy incorporates a sliding component within the inner cavity of a rotating component. As the rotating component rotates, the sliding component slides along a direction perpendicular to the axis of the grip under centrifugal force, achieving a dynamic telescoping effect. This provides the user with multiple physical feedbacks from rotation and sliding, enhancing the richness and fun of the stress-relief interaction. The telescoping motion of the sliding component creates a noticeable visual change during the toy's rotation. Through the design of the internal sliding component linked to the rotation, a dynamic response mechanism of "force → motion feedback" is introduced, improving the stress-relief toy's playability.
[0045] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0046] Please see Figures 1-11 The embodiments of this application provide a decompression toy 100, including a finger grip 10, a rotating component 20 and a sliding component 30;
[0047] The rotating assembly 20 includes a first rotating member 21 and a second rotating member 22 that overlap each other. The first rotating member 21 and the second rotating member 22 are both sleeved on the finger grip member 10 and rotatably connected to the finger grip member 10. The first rotating member 21 and the second rotating member 22 enclose and form an inner cavity 23.
[0048] A sliding component 30 is disposed within the inner cavity 23 and is slidably connected to the rotating component 20;
[0049] The direction perpendicular to the axis of the grip 10 is called the first direction. When the rotating component 20 rotates around the grip 10, the sliding component 30 is subjected to centrifugal force and slides along the first direction to partially extend or retract into the inner cavity 23.
[0050] Specifically, the first rotating component 21 and the second rotating component 22 together constitute a rotating shell, surrounding and covering the outside of the gripper 10; the two rotating components are connected by a "covering" method, which facilitates installation and accommodates the sliding structure; both are rotatably connected to the gripper 10 and can rotate around it in the axial direction; the inner cavity 23 is the accommodating space for the sliding assembly 30 to work. The inner cavity 23 forms a clear spatial isolation to prevent the sliding assembly 30 from falling out; the sleeve connection + rotational connection method allows the rotating assembly 20 to rotate stably around the gripper 10; it is beneficial to form a high coaxiality rotation system, enhancing the smoothness of rotation and service life.
[0051] Furthermore, the sliding component 30 rotates synchronously with the rotating component 20, but slides radially (in the first direction) relative to the body of the rotating component 20. During rotation, the sliding component 30 rotates synchronously under the drive of rotational force. Simultaneously, it is subjected to centrifugal force and slides outward radially. As it decelerates, the centrifugal force decreases, and the slider can retract. This centrifugal sliding generates dynamic feedback, providing a strong sense of stress relief. The user operation is intuitive; the sliding behavior can be triggered simply by rotating the component.
[0052] In one specific embodiment, the sliding component 30 includes a first sliding member 31 and a second sliding member 32 slidably connected to the first sliding member 31;
[0053] The first sliding member 31 extends outward on one side to form a first guide block 311, and the first rotating member 21 is provided with a first sliding groove 211 along the first direction on the side close to the first sliding member 31, and the first guide block 311 extends into the first sliding groove 211.
[0054] The second slider 32 extends outward on one side to form a second guide block 321. The first slider 31 is provided with a second sliding groove 221 along the first direction on the side close to the second slider 32. The second guide block 321 extends into the second sliding groove 221.
[0055] Specifically, this structure forms a two-stage telescopic sliding structure. The second slider 32 is embedded in the first slider 31, which is then connected to the rotating assembly 20. This creates a two-way sliding motion, enhancing the sense of depth and stress-relieving fun of the sliding changes. The first guide block 311 serves as a sliding guide between the first slider 31 and the first rotating assembly 21. It ensures that the first slider 31 slides smoothly in the radial direction, avoiding deviation or jamming. Simultaneously, it works in conjunction with the sliding groove to provide both limiting and guiding functions. Furthermore, the sliding resistance can be adjusted by changing the size of the guide block to achieve different tactile feedback.
[0056] In one specific embodiment, the first guide block 311 and the second guide block 321 are both disposed on both sides of the first slider 31 and the second slider 32.
[0057] Furthermore, the second-stage sliding guide mechanism causes the second slider 32 to move along the sliding groove of the first slider 31. This realizes the secondary sliding stroke inside the sliding assembly 30, forming a multi-layered, progressive telescopic structure.
[0058] In one specific embodiment, the first sliding member 31 includes a first sliding portion 312 and a second sliding portion 313 that overlap each other. The first sliding portion 312 and the second sliding portion 313 surround to form a sliding cavity 314. The second sliding member 32 is disposed in the sliding cavity 314. The side of the first sliding portion 312 near the second sliding portion 313 extends outward to form a stop portion 312a. The second sliding member 32 abuts against the stop portion 312a.
[0059] Specifically, the first sliding member 31 is divided into two assemblable parts, which are then fitted together to form an integral structure. This facilitates the encapsulation of the second sliding member 32 within the sliding cavity 314, while also improving process flexibility during manufacturing and subsequent assembly. The first sliding part 312 and the second sliding part 313 are fitted together to form a closed sliding cavity 314. The sliding cavity 314 is used to accommodate the second sliding member 32 and provide it with a controlled sliding path.
[0060] Furthermore, a stop 312a is disposed on the side of the first sliding part 312 near the second sliding part 313 and extends outward. The main function of the stop 312a is to limit the second sliding member 32, ensuring that it returns to its initial position upon retraction. The stop 312a ensures that the second sliding member 32 does not exceed the predetermined position when retracted, thereby maintaining the stability of the system and the integrity of the structure. This avoids excessive movement or misalignment of the sliding member, enhancing the operability and durability of the product.
[0061] In one specific embodiment, the sliding assembly 30 further includes a first elastic member 33, and the second sliding member 32 has a groove 313a along the first direction. One end of the elastic member is disposed at the bottom of the groove 313a, and the other end is disposed on the stop portion 312a, for pulling the second sliding member 32 back into the sliding cavity 314 after the rotating assembly 20 stops rotating.
[0062] Specifically, the groove 313a provides a mounting position for the first elastic element 33, allowing it to connect with the second sliding element 32. This enables the elastic element to more stably engage with the second sliding element 32, ensuring its proper function. The first elastic element 33 provides a counter-pulling force, ensuring that the second sliding element 32 automatically returns to its initial position after rotation, thus guaranteeing the stability and resettableness of the system. The addition of the elastic element avoids manual intervention, improving the toy's ease of use and reliability.
[0063] In one specific embodiment, the sliding component 30 further includes a second elastic element 34, one end of which is disposed on the first rotating component 21 and the other end of which is disposed on the first sliding component 31. The second elastic element 34 is used to pull the first sliding component 31 back into the inner cavity 23 after the rotating component 20 stops rotating.
[0064] Specifically, the function of the second elastic element 34 is to pull the first sliding element 31 back through its elastic restoring force. When the rotating assembly 20 stops rotating, the second elastic element 34 pulls the first sliding element 31 back into the inner cavity 23 through its elastic force. This ensures that the first sliding element 31 can automatically reset after stopping rotation without external force intervention.
[0065] In one specific embodiment, two second elastic members 34 are provided, with one end of each second elastic member 34 symmetrically disposed on both sides of the first rotating member 21.
[0066] Specifically, two second elastic elements 34 are used instead of a single elastic element. This allows the slider to return to the inner cavity 23 through the combined action of the two elastic elements after the rotating assembly 20 stops rotating. This dual design provides a more balanced restoring force, enabling the slider to return to its original position more smoothly and symmetrically.
[0067] Furthermore, when the device is not rotating, both the second elastic element 34 and the first elastic element 33 are in their natural, unstretched normal state, and the sliding element is in its initial position. When the rotating assembly 20 starts to rotate, the user pushes the rotating assembly 20, and the rotating assembly 20 rotates synchronously with the built-in sliding assembly 30. During the rotation, the first sliding element 31 and the second sliding element 32 are subjected to centrifugal force. The centrifugal force causes the sliding element to move outward radially (in the first direction), and the second elastic element 34 and the first elastic element 33 are stretched accordingly. The elastic elements store a certain amount of elastic energy due to the stretching. When the rotating assembly 20 stops rotating or the rotation speed decreases, the centrifugal force drops rapidly, and the second elastic element 34 and the first elastic element 33 release the stored elastic energy and begin to contract, thereby generating a retraction force. This retraction force causes the first sliding element 31 and the second sliding element 32 to be smoothly and automatically pulled back into the inner cavity 23, returning to their initial state.
[0068] In one specific embodiment, the elastic element is a spring.
[0069] Furthermore, the overall restoring force of the two elastic elements is greater than that of a single elastic element, ensuring that the first sliding element 31 and the second sliding element 32 are released and retracted in stages at different rotational speeds. This staged extension creates a distinct sense of layering and a dynamic visual effect, enhancing interactivity and enjoyment during use.
[0070] In one specific embodiment, the decompression toy further includes a limiting block 40, the second rotating member 22 has a countersunk hole 222, the first sliding member 31 has a through hole 315, the second sliding member 32 has a locking groove 322, and the axes of the countersunk hole 222, the through hole 315 and the locking groove 322 are on the same straight line.
[0071] The limiting block 40 is disposed in the countersunk hole 222, and the depth of the countersunk hole 222 is greater than the length of the limiting block 40. When the decompression toy is flipped over, the limiting block 40 partially slides down to extend into the through hole 315 and the engaging groove 322 to lock the sliding component 30.
[0072] Specifically, the limiting block 40 in this structure is mainly used to lock the sliding component 30. When flipped, the limiting block 40 partially slides down and enters the through hole 315 and the engaging groove 322, thereby restricting the radial movement of the first sliding member 31 and the second sliding member 32. The limiting block 40 only controls the extension and retraction of the sliding component 30, while the overall rotating component 20 maintains normal rotation. This creates two rotation modes, greatly increasing the product's fun and playability.
[0073] Furthermore, the central axes of the countersunk hole 222, the through hole 315, and the engaging groove 322 are aligned. This ensures that the limiting block 40 accurately aligns with the through hole 315 and the engaging groove 322 when released, thereby achieving effective locking. This improves assembly accuracy and the reliability of subsequent locking actions, avoiding incomplete locking or interference due to errors. The depth of the countersunk hole 222 must be greater than the length of the limiting block 40. Under normal conditions, it can be completely retracted into the countersunk hole 222. During rotation, the limiting block 40 partially slides down and enters the through hole 315 and the engaging groove 322, while still partially remaining within the countersunk hole 222, spanning all three sections to lock the sliding assembly 30 and the rotating assembly 20, ensuring the stability of the device under different conditions.
[0074] In summary, when the device is in normal operation, the first sliding member 31 and the second sliding member 32 rotate synchronously with the rotating component 20 under centrifugal force, exhibiting a graded extension effect, and the entire device is in a free telescopic mode. When the user flips the decompression toy, the flipping action causes part of the limiting block 40 to slip off. The limiting block 40 then enters the through hole 315 of the first sliding member 31 and the engaging groove 322 of the second sliding member 32, thereby locking the telescopic movement of the sliding component 30. The locking of the limiting block 40 only affects the radial movement of the sliding component 30; the user can still see or feel the rotating component 20 maintaining normal rotation on the axis.
[0075] In one specific embodiment, the sliding component 30 includes at least two.
[0076] Specifically, the decompression toy has two or more independent sliding components 30 inside, each of which can move independently radially during rotation.
[0077] In one specific embodiment, a plurality of the sliding components 30 are arranged in a ring around the finger grip 10.
[0078] Specifically, the sliding components 30 are evenly distributed in a ring around the finger grip 10. This ensures that the sliding components 30 are symmetrical in terms of force distribution and movement, guaranteeing that each sliding component 30 is subjected to a balanced centrifugal force regardless of how the toy rotates, thus achieving a stable dynamic response. The ring distribution balances the structural forces, reduces off-center loading, and ensures overall rotational stability and coordination; at the same time, this symmetrical layout enhances the product's aesthetics and complexity.
[0079] In one specific embodiment, the finger grip 10 includes a finger grip portion 11 and a rotating portion 12 sleeved on the finger grip portion 11. The rotating portion 12 is bearing-connected to the finger grip portion 11, and the side of the rotating portion 12 facing away from the finger grip portion 11 is fixedly connected to the rotating assembly 20.
[0080] Specifically, the finger grip portion 11 in the finger grip 10 is the part that the user directly holds. The function of the finger grip portion 11 is to provide a stable and comfortable contact surface, providing reliable support and a fixed foundation for subsequent rotational movements. The rotating part 12 is connected to the finger grip portion 11 through a bearing to achieve low-friction, high-precision rotational transmission, ensuring that the rotating part 12 can rotate smoothly around the axis of the finger grip portion 11.
[0081] Furthermore, the rotating part 12 is fixedly connected to the rotating assembly 20, which obtains stable and synchronous drive, transmits torque accurately and without deviation, so that the whole device maintains consistency and coordination when rotating, while keeping the grip part 11 in a fixed state, ensuring the user's comfort and stability when holding it.
[0082] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
