Description

Technical Field

[0001] This invention relates to the field of dance equipment technology, and in particular to a comprehensive training device for dance flexibility and rotation control. Background Technology

[0002] Instep stretches, leg kicks, spins, and splits are fundamental elements of dance training. Ballet, often hailed as the "mother of dance," employs a training system of "opening, stretching, straightening, and standing," which forms the basis for most dance styles. Instep stretches, in particular, often require the dancer to elevate the foot with the toes, keeping the sole almost straight with the lower leg. This reduces friction between the foot and the ground, facilitating turns and other movements, and also elevates the dancer's height, resulting in a more graceful posture and enhancing the overall performance. Leg kicks include front kicks, back kicks, and side kicks, with the back kick being one of the more challenging to master. Back kick training is further divided into kneeling and standing back kicks. During practice, the dancer first supports themselves on their supporting leg, then kicks the swinging leg backward and upward. Initially, the swinging leg doesn't require a specific height, but this is gradually increased as the dancer becomes more proficient. Dance rotation training is a common training movement in dance training, and it is also one of the more difficult dance movements. Rotation is an important part of the technical skills in the dance training system. Smooth rotation can attract the audience's attention. Almost all dances cannot do without rotation.

[0003] Typically, dancers need to use auxiliary equipment during training, such as for instep pressing exercises. A common example is the instep pressing machine disclosed in Chinese Patent Publication No. CN203425472U, which is integrally molded and includes a clamping part, which is a long rod. This clamping part is a thick section with a rectangular cross-section, facilitating the placement of the calf. A shaping part is located below the clamping part. The front of the shaping part is slightly W-shaped along its longitudinal direction. From top to bottom, the front of this part includes a first convex part, a concave part, a second convex part, and a front edge. The length of the shaping part is approximately equal to the length from the ankle to the toes. The size and shape of the first convex part roughly correspond to the ankle; the shape of the concave part roughly corresponds to the heel; the shape of the second convex part roughly corresponds to the arch of the foot; and the front edge is generally flat, allowing the toes to rest. The aforementioned foot-pressing machine, when performing extreme movements, such as straightening and pressing the instep, usually requires dancers to press the instep themselves with their hands, requiring assistance from others to complete the movement practice, which causes trouble for dancers.

[0004] In addition, dancers usually use a foot-pressing machine, such as the one disclosed in Chinese Patent Publication No. CN116603218A, during back kick training, and an auxiliary device for training high-difficulty dance movements, such as the one disclosed in Chinese Patent Publication No. CN114452624B, during rotation training. There is no integrated dance training device that combines foot-pressing, back kicking, and rotation, which brings great inconvenience to the dancers' training.

[0005] Therefore, there is a need to design a dance training device that can solve the above problems. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the purpose of this invention is to provide a comprehensive training device for dance flexibility and rotation control, so as to solve the problems that dancers need assistance from others when performing leg pressing movements and that multiple training programs require changing training devices.

[0007] This invention provides a comprehensive training device for dance flexibility and rotation control, comprising:

[0008] A base plate, wherein two supports are fixed to the upper end of the base plate, and top rods are provided at the top of the two supports;

[0016] Specifically, the bracket has a vertically driven lifting module on its inner side, which is used to adjust the height of the leg press bar.

[0017] Specifically, the lifting module includes two gears located at the upper and lower ends of the inner side of the bracket, a first motor for driving any one of the gears, a gear chain meshing with the two gears, and a slider fixed on the gear chain. The slider has a bushing at one end facing the leg press rod, and the end of the leg press rod is sleeved with the bushing.

[0018] Specifically, the bottom of the carrier plate is provided with a toothed groove for adjusting the rotational position radially along the leg presser.

[0019] Specifically, the carrier plate is provided with an elastic strap at the end facing the leg press bar, and the elastic strap can be retracted to adjust its size.

[0020] Specifically, the presser foot back assembly includes a second motor fixed to the bottom of the carrier plate, a take-up shaft connected to the output end of the second motor, and a presser foot belt wound by the take-up shaft. The non-wound end of the presser foot belt is fixed to the side of the carrier plate, and a pressing area for extending into the user's instep is formed between the presser foot belt and the upper surface of the carrier plate.

[0021] The beneficial effects of this invention are:

[0022] This invention discloses a comprehensive training device for dance flexibility and rotation control. A rotation training module is installed on the base plate. When performing rotation training, dancers can stand on the support and rotate the support via a drive unit, facilitating rotation training. At least one leg training module is installed on the leg pressing bar. When dancers need to perform instep pressing training, they can stand facing the leg training module, place their legs on the platform, and use the instep pressing component for automatic instep pressing training. When dancers need to perform back kick training, they can stand facing the leg training module, place their legs behind the platform, turn around and stand facing away from the leg training module, grasp the handle, and use the pull rope to pull the platform upwards, completing the back kick technique without assistance, allowing dancers to complete training independently.

Detailed Implementation

[0033] This invention provides a comprehensive training device for dance flexibility and rotation control. To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention.

[0034] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0035] like Figures 1 to 8 As shown, this embodiment discloses a comprehensive training device for dance flexibility and rotation control, comprising:

[0036] The base plate 10 has two brackets 11 fixed at its upper end, and the top of the two brackets 11 is provided with a top rod 12.

[0037] The rotating training module 20 includes a rotating driver 21 vertically mounted on the base plate 10 and a support 22 connected to the drive shaft of the rotating driver 21 and for the user to stand on.

[0038] The leg press bar 30 is detachably installed between the two brackets 11;

[0039] At least one leg training module 40 includes a carrier plate 41 rotatably mounted on a leg press bar 30, a foot press assembly 42 located at one end of the carrier plate 41 and used to press the user's instep, a pull rope 43 for pulling the carrier plate 41 to swing upward, and a handle 44 connected to the end of the pull rope 43, the pull rope 43 being suspended from a top bar 12.

[0040] The dance flexibility and rotation control integrated training device of this embodiment has a rotation training module 20 set on the base plate 10. The rotation training module 20 includes a rotation driver 21 and a support 22. When the dancer is performing dance rotation training, he / she can stand on the support 22 and drive the support 22 to rotate through the rotation driver 21, thereby driving the dancer to rotate, which makes it convenient for the dancer to perform rotation training.

[0041] It should be noted that when dancers are training, they usually adjust different rotation speeds to adapt to different rotation speeds. Based on this, the rotary actuator 21 used in this embodiment can be a motor or motor gear set that can automatically adjust the rotation speed, and can be used with a wireless control terminal, such as a remote control, voice controller, touch screen controller, etc. The dancer can stand on the support 22 and control the rotary actuator 21 through the wireless control terminal. When the rotary actuator 21 is working, it drives the support 22 to rotate through its rotation shaft, thereby using the rotation of the support 22 to drive the dancer to rotate and assist the dancer in training rotational movements.

[0042] Furthermore, to improve the dancer's body coordination during spins, please refer to... Figure 3 and Figure 4 In this embodiment, the support member 22 includes a pad 221 connected to the drive shaft of the rotary driver 21 and an unbalanced device 222 disposed on the pad 221. The unbalanced device 222 has a hemispherical structure. When dancers step on the hemispherical unbalanced device 222, they can practice their body coordination.

[0043] It should be noted that the connection between the unbalanced device 222 and the pad 221 in this embodiment can be a detachable connection method such as screw fixing, adhesive fixing, threaded connection, or snap-fit ​​connection. When the unbalanced device 222 is not needed, it can be quickly removed, and the dancer can stand directly on the pad 221 to perform rotation training.

[0044] It should be noted that the unbalanced device 222 can be made of elastic materials such as rubber, styrene-butadiene rubber, neoprene rubber, HDPE, EVA, and high-density polyethylene, providing dancers with a good foot feel and also having anti-slip and anti-fall effects.

[0045] Dancers are very prone to falls and injuries due to loss of balance during the initial stages of spin training. To improve safety during spin training, please refer to... Figure 1 As shown, the top rod 12 is equipped with a protective module 50, which is used to limit and protect the user's shoulders or waist during rotation training.

[0046] For further details, please refer to... Figure 4 The protective module 50 in this embodiment includes a top plate 51 fixed to the top rod 12, a hanging plate 52 rotatably mounted on the top plate 51, a telescopic rod 53 connected to the lower end of the hanging plate 52, and a limiting frame 54 connected to the lower end of the telescopic rod 53. By setting the protective module 50, when using the device for assisted rotation training, the dancer can first adjust the height of the limiting frame 54 according to their own height using the telescopic rod 53, so that the limiting frame 54 can limit and protect the dancer's shoulders or waist, thereby preventing the dancer from losing balance and falling and getting injured when performing rotational movements, thus improving the safety of the device.

[0047] Of course, the restraint frame 54 can be designed as an arc-shaped protective plate structure, and made of a material with a certain degree of elasticity. When it provides restraint protection for the dancer's shoulders or waist, the elastic material provides a good and comfortable experience for the user. In addition, the restraint frame 54 can also be designed as a wristband, and two of them can be designed, with the height of the restraint frame 54 appropriately adjusted so that the dancer can hold the restraint frame 54 with both hands, thereby preventing the dancer from losing balance and falling and getting injured.

[0048] The dance flexibility and rotation control integrated training device of this embodiment features a detachable leg press bar 30, which can be removed when performing rotation training module 20. At least one leg training module 40 is installed on the leg press bar 30, including a carrier plate 41, a foot press assembly 42, a pull rope 43, and a handle 44. When a dancer needs to perform foot press training, they can stand facing the leg training module 40, place their legs on the carrier plate 41, and use the foot press assembly 42 to automatically press their foot, eliminating the need for assistance and allowing the dancer to complete the training independently. When a dancer needs to perform back kick training, they can stand facing the leg training module 40, place their legs behind the carrier plate 41, turn around and stand facing away from the leg training module 40, grasp the handle 44, and use the pull rope 43 to pull the carrier plate 41 upwards, completing the back kick technique without assistance, again allowing the dancer to complete the training independently.

[0049] For further details, please refer to... Figure 8 As shown, the leg training module 40 in this embodiment also includes an angle limiter 45. The angle limiter 45 is used to limit the swing angle of the carrier plate 41. When the pull rope 43 is not pulled, the carrier plate 41 can be kept horizontal. The angle limiter 45 is implemented by a circular sleeve and two locking blocks. The sleeve is sleeved on the outside of the leg pressing bar 30. One locking block is fixed to the inside of the sleeve, and the other locking block is fixed to the leg pressing bar 30. When the carrier plate 41 is placed horizontally, under the blocking and limiting effect of the two locking blocks, the sleeve can only rotate in one direction.

[0050] It should be noted that the angle limiter 45 in this embodiment adopts a sleeve and a locking block, which is only a preferred implementation method. In other embodiments, methods such as suspension by rope or baffle to prevent the carrier plate 41 from swinging down can also be used, and it is not limited to the limiting method mentioned in this embodiment.

[0051] To accommodate users of different heights, please refer to [the relevant documentation / reference]. Figure 1 As shown, the bracket 11 has a vertically driven lifting module 60 on its inner side, which is used to adjust the height of the leg press bar 30.

[0052] For further details, please refer to... Figure 3 and Figure 4As shown, the lifting module 60 of this embodiment includes two gears 61 located at the upper and lower ends of the inner side of the bracket 11, a first motor 62 for driving any one of the gears 61, a toothed chain 63 meshing with the two gears 61, and a slider 64 fixed on the toothed chain 63. The slider 64 has a bushing 65 at one end facing the leg press rod 30. The end of the leg press rod 30 is sleeved with the bushing 65. After the end of the leg press rod 30 is inserted into the bushing 65, it is fixed by locking parts such as pins 75 to prevent the leg press rod 30 from being misaligned. In addition, in order to realize the disassembly and assembly of the leg press rod 30, at least one end of the leg press rod 30 needs to be designed as a telescopic structure to facilitate its disassembly after retraction.

[0053] For further details, please refer to... Figure 2 , 5 As shown, the bottom of the carrier plate 41 in this embodiment is provided with a toothed groove 46 for adjusting the rotational position along the radial direction of the leg presser 30. The rotational position of the carrier plate 41 along the radial direction of the leg presser 30 can be adjusted through the toothed groove 46, such as... Figure 6 As shown, when a dancer performs instep pressing exercises, they can stand facing the leg training module 40 and pull the carrier plate 41 towards the dancer, so that the pivot point of the carrier plate 41 is as close as possible to the center of the carrier plate 41, making it easier for the dancer to perform instep pressing exercises; as Figure 7 As shown, when a dancer performs a back kick training, the user's hips need to open to a large extent, and if the pivot point is too far away, it will be detrimental to the back kick movement. Therefore, the carrier plate 41 can be pulled away from the dancer so that the pivot point of the carrier plate 41 is as close to the dancer as possible, making it easier for the dancer to perform back kick training.

[0054] For further details, please refer to... Figure 2 As shown, the carrier plate 41 is provided with an elastic strap 47 at the end facing the leg press bar 30. The elastic strap 47 can be retracted to adjust its size. The elastic strap 47 is used to bind the user's legs. The elastic strap 47 can be fitted with Velcro, buckles, or other structures to adjust its size.

[0055] For further details, please refer to... Figure 5 , 6 As shown, the presser foot back assembly 42 includes a second motor 421 fixed to the bottom of the carrier plate 41, a take-up shaft 422 connected to the output end of the second motor 421, and a presser foot strap 423 wound up by the take-up shaft 422. The non-wound end of the presser foot strap 423 is fixed to the side of the carrier plate 41. A pressing area for inserting into the user's instep is formed between the presser foot strap 423 and the upper surface of the carrier plate 41. The second motor 421 can be a motor or motor gear set that can automatically adjust the speed, and can be used with a wireless control terminal, such as a remote control, voice controller, touch screen controller, etc. The dancer can control the second motor 421 to work through the wireless control terminal. When the second motor 421 works, it drives the presser foot strap 423 to rewind through the take-up shaft 422, thereby performing the presser foot back action.

[0056] For further details, please refer to... Figure 1 and Figure 2 As shown, the top rod 12 in this embodiment is also provided with a pulley 71, and the pull rope 43 is laid on the pulley 71. The pulley 71 reduces the pulling friction of the pull rope 43 and improves the service life of the pull rope 43.

[0057] For further details, please refer to... Figure 4 As shown, the rotation training module 20 in this embodiment also includes a bearing 72, which is sleeved on the drive shaft of the rotation driver 21. The bearing 72 reduces the rotational friction of the support member 22 and avoids wear on the bottom of the support member 22.

[0058] Furthermore, the pull rope 43 is a spring rope, which has the characteristics of high strength, wear resistance, and good flexibility.

[0059] For further details, please refer to... Figure 1 As shown, the lower end of the base plate 10 in this embodiment is also provided with a support leg 73, and a suction cup 74 is provided on the support leg 73. The suction cup 74 can be used to stick to the ground to prevent the dance flexibility and rotation control integrated training device from sliding on the ground.

[0060] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of the present invention.
