Description

Technical Field

[0001] The utility model relates to the technical field of limb movement assistance, in particular to an auxiliary training device that can be used for street dance movements. Background Art

[0002] There are many different types of street dance, including Breaking and Hip-Hop. Breaking (also known as floor dance) is known for its challenging, powerful moves and techniques. Dancers often use their hands, elbows, head, back, and other body parts to perform spins, tumbles, and handstands on the ground. For example, the iconic Thomas Spin, where the dancer supports themselves with their hands while their legs spin through the air like a pinwheel, demonstrates strong upper body strength and coordination.

[0003] In traditional street dance training, dancers primarily rely on their own experience, on-the-spot guidance from teachers, and repeated practice to improve. However, teachers have limited energy, making it difficult to provide precise and timely guidance to each dancer at every training moment. Furthermore, dancers lack objective and accurate feedback during practice, making it difficult to detect subtle flaws in their movements. For example, during difficult spins, a dancer's center of gravity might shift slightly, affecting the quality of their movements, yet they struggle to detect and correct them.

[0004] Most standard fitness equipment on the market is designed for general purposes like body shaping and strength training, and cannot meet the specific needs of street dance movement training. Street dance movements emphasize dynamic body control, rhythmic control, and unique body movement combinations. Standard fitness equipment cannot simulate the movement environment and force generation methods of street dance. For example, some strength training equipment can only perform strength training in a single direction and cannot help dancers develop the multi-directional and multi-angle force bursts and transition techniques required for street dance.

[0005] Although there are some dance aids, such as poles and yoga mats, these tools are not very targeted for street dance movements. Some special movements in street dance, such as various floor movements in Breaking, cannot be completed with the help of poles or yoga mats. Utility Model Content

[0036] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0037] Example 1

[0038] In order to facilitate street dance learners to train body movements, especially to train Thomas full spin, this embodiment provides an auxiliary device for street dance movement training, which can reduce the dancer's gravity burden, help the dancer maintain body balance, and reduce the risk of injury.

[0039] like Figure 1As shown, specifically, the auxiliary training device includes a platform 1, a connecting plate group 2, a support rod group 3, a suspension assembly 4, etc. The connecting plate group 2 is arranged on the side of the platform 1, and the end is hinged to the platform 1, so that the connecting plate group 2 can rotate around the platform 1. The support rod group 3 is arranged in an L-shaped structure, the bottom of the support rod group 3 is connected to the connecting plate group 2, and the top of the support rod group 3 is hingedly connected to the suspension assembly 4. When using this device to assist dancers in continuous street dance movements, especially in the Thomas full spin, the dancers support their palms on the platform 1, and their legs are suspended in the air by the action of the suspension assembly 4. In this way, the dancers can control the rotation of their legs in the air by changing the position of their arms, avoiding injuries caused by imbalance due to beginners not yet mastering the movements.

[0040] like Figure 1 、 Figure 11 As shown, in order to enable the legs to rotate in the air and avoid causing the suspension assembly 4 to be entangled. The platform 1 is set as an I-shaped structure. The connecting plate group 2 includes a main board 21 and a movable plate 26. The movable plate 26 is adjustably set on the side of the main board 21, and the movable plate 26 is connected to the support rod group 3. A fixed arc plate 22 is fixedly set at the end of the main board 21, and a clamping arc plate 24 is connected to the side of the fixed arc plate 22 by bolts. A bearing 23 is set in the space formed by the clamping arc plate 24 and the fixed arc plate 22. The bearing 23 is sleeved on the platform 1. Therefore, under the action of the bearing 23, the main board 21 is movably set on the side of the platform 1 and can rotate around the platform 1, which provides support for the suspension assembly 4 to rotate with the trainee's legs. Because the clamping arc plate 24 is detachably set on the side of the fixed arc plate 22, the connecting plate group 2 and the platform 1 can be quickly disassembled as needed.

[0041] like Figure 11 As shown, in order to enable the fixed arc plate 22 and the clamping arc plate 24 to be stably installed relative to the bearing 23, arc-shaped protrusions 241 are provided on the inner side surfaces of the fixed arc plate 22 and the clamping arc plate 24. The arc-shaped protrusions 241 are distributed on the upper and lower sides of the bearing 23 to limit the position of the fixed arc plate 22 and the clamping arc plate 24 relative to the bearing 23, and prevent the fixed arc plate 22 and the clamping arc plate 24 from separating from the bearing 23 under the action of external force.

[0042] like Figure 12As shown, to achieve an adjustable connection between the main plate 21 and the movable plate 26, a slot 211 is provided at the end of the main plate 21, and an insert plate 261 is fixedly mounted on the end surface of the movable plate 26. The cross-sections of the insert plate 261 and the slot 211 are both configured to have uneven shapes. Therefore, when the insert plate 261 is inserted into the slot 211, the movable plate 26 and the main plate 21 are adjustable and stably connected, and it is convenient for different trainees to adjust the length of the connecting plate assembly 2 and the position of the suspension assembly 4. To ensure the relative stability of the main plate 21 and the movable plate 26 during adjustment, a bolt can be threaded through the insert plate 261, with the end of the bolt pressing against the side wall of the slot 211, or a rubber layer can be provided on the contact surface between the insert plate 261 and the slot 211 to increase the resistance of the insert plate 261 to movement within the slot 211.

[0043] like Figure 13 As shown, in order to support the connecting plate group 2 to rotate stably around the product table 1, a bracket 25 is provided below the main board 21. The bracket 25 includes a common plate 251 and two universal wheels 253. The two universal wheels 253 are respectively provided at the two ends below the common plate 251. A top shaft 252 is fixedly provided in the middle above the common plate 251. The top shaft 252 is connected to the main board 21. The structural characteristics of the universal wheel 253 are utilized to provide support for the connecting plate group 2 to rotate around the axis while stably supporting the connecting plate group 2.

[0044] like Figure 7 As shown, in order to stably install the suspension component 4 at a high place, the support rod group 3 includes a vertical rod 31, a horizontal rod 33 and a bent pipe 32. The bent pipe 32 is set as a right-angle structure, the top of the vertical rod 31 is inserted into the bent pipe 32, and the bottom of the vertical rod 31 is inserted into the end of the movable plate 26. The horizontal rod 33 is set as an L-shaped structure, and one end is inserted into the bent pipe 32.

[0045] like Figure 8 As shown, in order to lift the trainee's legs through the suspension assembly 4, the suspension assembly 4 includes a horizontal plate 43, two sets of connecting mechanisms 42 and two suspension belts 41. The two suspension belts 41 are folded and arranged under the connecting mechanism 42. The two sets of connecting mechanisms 42 are adjustably mounted on both ends of the horizontal plate 43. When using this device, the suspension belts 41 are mounted on the trainee's legs, and then the trainee's legs are supported under the action of the suspension belts 41, providing support for the trainee to perform continuous Thomas full spins.

[0046] like Figure 7 、 Figure 9As shown, in order to stably and rotatably arrange the suspension assembly 4 below the cross bar 33, a threaded structure 34 is provided on the vertical section of the cross bar 33. A sleeve pipe 431 is fixedly arranged in the middle of the cross plate 43. A thrust bearing 433 is arranged below the sleeve pipe 431, and a nut 434 is arranged below the thrust bearing 433. The sleeve pipe 431 and the thrust bearing 433 are both sleeved on the vertical section of the cross bar 33, and the nut 434 is threadedly sleeved on the cross bar 33. Therefore, the thrust bearing 433 and the sleeve pipe 431 are stably sleeved on the cross bar 33. Under the action of the thrust bearing 433, the resistance of the cross plate 43 to rotate is reduced, and at the same time, the stable installation of the cross plate 43 relative to the cross bar 33 is realized.

[0047] As Figure 9 , Figure 10 shown, in order to stably install the suspension belt 41 below the cross plate 43, the connecting mechanism 42 includes a connecting block 421, a fixing plate 424 and two clamping plates 422. The connecting block 421 is arranged in a U-shaped structure with an upward opening and is sleeved on the cross plate 43. Specifically, a clamping column 429 is fixedly arranged on the inner side wall of the connecting block 421, and a clamping groove 432 is arranged on the vertical side wall of the cross plate 43. The clamping groove 432 is arranged along the length direction of the cross plate 43 and the end is set to be open. Therefore, the clamping column 429 is located in the clamping groove 432, realizing the stable connection between the connecting block 421 and the cross plate 43, and facilitating the adjustment of the position of the connecting block 421 relative to the cross plate 43 according to needs, so as to adapt to different requirements for promoting training actions. In order to stably place the adjusted connecting block 421 relative to the cross plate 43, a bolt can be threadedly penetrated through the connecting block 421, and the end of the bolt presses against the side wall of the cross plate 43, increasing the resistance of the connecting block 421 to move relative to the cross plate 43.

[0048] As Figure 10 shown, the fixing plate 424 is fixedly arranged in the middle below the connecting block 421. The two clamping plates 422 are distributed on both sides of the fixing plate 424 and are connected to the fixing plate 424 through bolts. When the two free ends of the suspension belt 41 respectively extend into the gap formed by the fixing plate 424 and the two clamping plates 422, by rotating the bolts, the clamping plates 422 are forced to move and cooperate with the fixing plate 424 to squeeze the suspension belt 41, thereby stably installing the suspension belt 41 relative to the connecting block 421. A limiting frame 411 can also be sleeved on the suspension belt 41, and the suspension belt 41 is contracted through the limiting frame 411, so as to stably support the legs of the training personnel at the bottom of the suspension belt 41.

[0049] As Figure 10 shown, in order to be able to adjust the position of the bottom of the suspension belt 41, a through hole 427 is arranged on the side wall of the clamping plate 422, and the size of the through hole 427 is larger than the size of the suspension belt 41. Therefore, after the end of the suspension belt 41 penetrates through the through hole 427, the height of the bottom of the suspension belt 41 can be adjusted by adjusting the length of the suspension belt 41 extending out of the clamping plate 422.

[0050] like Figure 10 As shown, in order to make the suspension belt 41 more stably installed between the clamping plate 422 and the fixing plate 424, a groove 425 is provided on the side wall of the fixing plate 424, and a protrusion 423 is fixedly provided on the side walls of the two clamping plates 422 close to each other. Therefore, under the action of the bolt, the protrusion 423 presses the suspension belt 41 into the groove 425, thereby further increasing the resistance to the movement of the suspension belt 41.

[0051] like Figure 10 As shown, in order to stably install the clamping plate 422 on the connecting block 421, snap grooves 428 are provided at both ends of the lower side of the connecting block 421. The two snap grooves 428 are arranged along the length direction of the connecting block 421, and the ends away from each other are set to be open. A snap plate 426 is fixedly provided on the top of the clamping plate 422, and the snap plate 426 is installed in the snap groove 428 to achieve stable connection between the clamping plate 422 and the connecting block 421, and at the same time provide support for controlling the movement of the clamping plate 422 to clamp the suspension belt 41.

[0052] Example 2

[0053] like Figure 2-6 As shown, on the basis of Example 1, in order to enable the trainee to train rotation and adapt to the dizziness caused by rotation, the platform 1 includes a bottom plate 11 and a top plate 12, a support tube 111 is fixedly provided in the middle above the bottom plate 11, and an inner tube 122 and an outer tube 123 are fixedly provided in the middle below the top plate 12, the inner tube 122 is inserted into the support tube 111 through a bearing connection, and the outer tube 123 is sleeved on the outside of the support tube 111, so that the top plate 12 and the bottom plate 11 are stably and movably connected, so that the top plate 12 can rotate while supporting the trainee so that the trainee can adapt to the dizziness state.

[0054] To ensure that the top plate 12 remains stationary relative to the bottom plate 11, a first polygonal groove 112 is provided in the middle of the upper portion of the bottom plate 11. The first polygonal groove 112 is positioned between the support tubes 111. A second polygonal groove 121 is provided in the middle of the upper side of the top plate 12. A limiting rod 13 is positioned within the space formed by the second polygonal groove 121 and the inner tube 122. A first polygonal post 131 and a second polygonal post 133 are positioned at either end of the limiting rod 13. The first polygonal post 131 and the second polygonal post 133 respectively retract into the second polygonal groove 121 and the first polygonal groove 112. Therefore, once the limiting rod 13 is inserted into the platform 1, the top plate 12 and the bottom plate 11 remain stationary relative to each other, facilitating the trainee's ability to perform a Thomas full spin. A gripping groove 132 is provided on the top surface of the first polygonal post 131. The trainee's finger can be inserted into the gripping groove 132 to control the movement of the limiting rod 13 and release it from the platform 1, facilitating the rotation of the top plate 12 while supporting the trainee.

[0055] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
