Description

Technical Field

[0001] This utility model belongs to the field of fitness equipment technology, and specifically relates to a rhythmic device. Background Technology

[0002] Rhythmic devices are passive motion mechanisms that operate at a fixed frequency. They can induce users to mimic the motion of skipping rope, thereby affecting the endocrine and other physiological systems to produce various health benefits.

[0003] Most rhythmic devices on fitness equipment currently on the market include a vertically sliding support plate. During use, a motor drives an eccentric mechanism to move the support plate vertically. For example, the reciprocating rhythmic device disclosed in Chinese Utility Model Patent Application CN202320685664.0 includes a base, a drive assembly, a first actuating mechanism, and a second actuating mechanism. The drive assembly includes a motor, a first one-way bearing, and a second one-way bearing. The first one-way bearing includes a first inner ring and a first outer ring. The first inner ring is mounted on the motor, and the first outer ring is fitted onto the first inner ring and rotates in a first direction. The second one-way bearing includes a second inner ring and a second outer ring. The second inner ring is mounted on the motor, and the second outer ring is fitted onto the second inner ring and rotates in a second direction. When the first direction rotates, the first outer ring drives the first actuating mechanism to perform a first reciprocating rhythm; when the second direction rotates, the second outer ring drives the second actuating mechanism to perform a second reciprocating rhythm, thereby simplifying the structure.

[0004] The rhythmic device in the above structure is relatively complex, inconvenient to manufacture and assemble, and requires a specific housing. It is mostly used in the rhythmic motor. Summary of the Invention

Detailed Implementation

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0033] See Figures 1 to 8 As shown, a rhythmic device includes a connecting seat 1 and a support seat 2 that are movably connected. The connecting seat 1 is provided with a fixing member 13 for connecting to other objects. The support seat 2 is provided with a roller 3 for supporting the support seat 2. An eccentric shaft 35 is provided on the roller 3. The roller 3 is rotatably mounted on the support seat 2 via the eccentric shaft 35. During the rotation of the roller 3, the distance between the eccentric shaft 35 and the lower end of the roller 3 changes, causing the support seat 2 and the connecting seat 1 to move relative to each other, thereby causing the support seat 2 to undulate up and down. This rhythmic device includes a connecting seat 1, a support seat 2, and a roller 3. It has a simple structure, low production cost, and is convenient for production and assembly. During the rotation of the roller 3, the eccentric shaft 35 can cause the support seat 2 to vibrate up and down. Moreover, this rhythmic device can be installed on an object through the fixing member 13, and the roller 3 can be driven to rotate by a hub motor or other devices, which facilitates the flexible use of the rhythmic device.

[0034] The connecting seat 1 and the support seat 2 can be slidably connected. In this embodiment, the connecting seat 1 and the support seat 2 are rotatably connected. The connecting seat 1 is provided with a hinge groove 14, and one end of the support seat 2 is rotatably disposed in the hinge groove 14.

[0035] The connecting seat 1 described in this utility model includes a connecting member 11 connected to the support seat 2. An extension rod 12 is movably disposed on the connecting member 11, and a fixing member 13 is disposed on the extension rod 12. The extension rod 12 facilitates the flexible installation of the connecting seat 1, allows the user to adjust the installation position of the support seat 2 as needed, facilitates the flexible installation of the rhythm device, and makes it easy for the user to install the rhythm device on different objects.

[0036] The connector 11 can be rotatably connected to the extension rod 12, and the connector 11 can also be slidably connected to the extension rod 12. The connector 11 can also have multiple mounting positions. By installing the extension rod 12 in different mounting positions, the relative positions of the connector 11 and the extension rod 12 can be changed. In this embodiment, the connector 11 and the extension rod 12 are preferably slidably connected. The user can fix the connector 11 and the extension rod 12 relative to each other with fasteners.

[0037] The connector 11 described in this utility model is provided with at least two extension rods 12, and each extension rod 12 is provided with a fixing member 13. The extension rods 12 can extend to both sides of the support seat 2 respectively. The extension rods 12 extending to both sides of the support seat 2 are conducive to the stable installation of the rhythm device, avoid the connection seat 1 being subjected to force on one side, which would cause the rhythm device to tilt during use, and facilitate the use of the rhythm device.

[0038] The connecting seat 1 is provided with a locking element 4, and the support seat 2 is provided with a positioning part 25 adapted to the locking element 4. The locking element 4 and the positioning part 25 are connected to restrict the relative movement of the connecting seat 1 and the support seat 2 or to control the relative fixation of the connecting seat 1 and the support seat 2. The setting of the locking element 4 and the positioning part 25 allows the connecting seat 1 and the support seat 2 to be relatively fixed, which facilitates the storage and transportation of the rhythm device.

[0039] Preferably, the roller 3 has a cylindrical sidewall 31 and an eccentric hole 33 is provided in the roller 3. The eccentric shaft 35 is rotatably disposed in the eccentric hole 33 through the bearing 34. The cylindrical sidewall 31 is conducive to the stable rotation of the roller 3 and facilitates the support seat 2 to move up and down reciprocally according to a specific amplitude. This structure is also convenient for manufacturing and processing. The setting of the eccentric hole 33 and the bearing 34 facilitates the stable installation of the roller 3.

[0040] In this embodiment, the roller 3 is provided with anti-slip texture 32 on its outer periphery. The anti-slip texture 32 can drive the roller 3 to rotate and make the support seat 2 move up and down. The anti-slip texture 32 makes it easy for the roller 3 to rotate under force, avoids excessive force on the support seat 2 which would cause the roller 3 to slip, and is conducive to stable movement during use, making it convenient for users to exercise.

[0041] The support base 2 includes a support frame 22, which extends toward the connecting base 1 to form a connecting rod 21. The connecting rod 21 is movably connected to the connecting base 1. The setting of the connecting rod 21 can extend the distance between the cushion 24 and the connecting base 1, which helps to reduce the back-and-forth swing of the cushion 24 during use, making it easier for the user to stand or sit stably on the cushion 24, and making it convenient for the user to use.

[0042] A seat cushion 24 is provided on the support frame 22, and rollers 3 are installed on the support frame 22 and located below the center of the seat cushion 24. The seat cushion 24 is provided to improve the comfort of the rhythm device. A mounting frame 23 extends below the support frame 22. The rollers 3 are rotatably mounted on the mounting frame 23 via an eccentric shaft 35. Preferably, a set of rollers 3 is provided below the support seat 2. A set of rollers 3 may include one roller 3 or multiple rollers 3 rotating synchronously.

[0043] A treadmill includes a frame 5 and a drive motor. A running belt 6 and a drive roller are movably mounted on the frame 5. The drive motor can drive the running belt 6 to move relative to the frame 5 via the drive roller. The treadmill also includes the aforementioned vibration device. A connecting seat 1 is detachably connected to the frame 5. A roller 3 abuts against the running belt 6. When the drive motor drives the running belt 6 to move, the running belt 6 can drive the roller 3 to rotate relative to the support seat 2. In this structure, the running belt 6 drives the roller 3 to rotate, thereby causing the support seat 2 to vibrate up and down. This enhances the functionality of the treadmill, makes it more convenient for users, and eliminates the need for users to purchase a separate vibration device, thus reducing fitness costs.

[0044] The treadmill is a fitness equipment, in which the drive motor drives the running belt 6 through the drive roller, which is a common result. Although this utility model discloses the structure of the treadmill, those skilled in the art can realize this technical solution based on the description and the accompanying drawings.

[0045] The frame 5 includes two uprights 51 extending upwards, with a handrail 52 between the uprights 51. The connecting seat 1 is provided with two fixing parts 13, which are detachably connected to the two uprights 51 respectively. The connecting seat 1 and the frame 5 are fixedly connected by the two fixing parts 13. The structure is simple and facilitates the stable installation of the rhythm device.

[0046] In this utility model, a storage space is provided between the two uprights 51. The support base 2 can be flipped up to the top of the connecting base 1 and stored in the storage space. The storage space facilitates the storage of the support base 2. Users do not need to remove the rhythm device from the treadmill to use the treadmill, which is convenient for users to exercise. When the support base 2 is stored in the storage space, the locking part 4 and the positioning part 25 cooperate to fix the support base 2 and the connecting base 1 relative to each other, thereby preventing the support base 2 and the connecting base 1 from moving relative to each other.

[0047] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
