Description

Technical Field

[0001] This invention relates to the field of Pilates fitness equipment technology, specifically to a multi-mode Pilates stability bench suitable for inverted training and its usage method. Background Technology

[0002] The Stable Step Chair is a classic piece of equipment in the Pilates training system. Its basic structure includes a frame-like support body, spring-loaded pedals, and optional armrests, primarily used for core strength and balance control training. With the development of training methods, some practitioners have adapted the Stable Step Chair for inversion exercises, using the spring force of the pedals to assist in lower limb rotation to achieve an inversion. This usage is gradually becoming popular among students with some basic skills. (See also...) Figure 1 .

[0003] In the field of inversion training equipment, there are already a variety of auxiliary solutions. For example, CN104797304A discloses an inversion exercise equipment that also functions as a seat, which achieves the transformation between the seat and the inversion equipment through gear transmission; US20070032358A1 discloses an electric inversion training platform, in which the user first lies horizontally and then is driven by a motor to flip into an inverted state to alleviate the fear of flipping; US6679818 discloses a tilt angle locking device for inversion equipment to prevent the user from suddenly flipping to the maximum angle.

[0004] However, the aforementioned existing inversion equipment are all specialized devices and cannot be integrated with the Pilates training system. Using existing footrests directly for inversion training has the following drawbacks: First, the fixed position of the footrest assist structure limits the rotation angle and fails to provide support and protection for the user's chest and abdomen after inversion. Beginners may experience fear due to loss of balance, making it difficult to complete the training independently. Second, the spring-assisted method requires a certain level of muscle control, which is too difficult for beginners and cannot cater to the diverse needs of users at different training levels. Third, the lack of a multi-mode switching mechanism prevents flexible adjustments to the assistance method and level of protection based on the user's skill level.

[0005] Therefore, it is necessary to improve the structure of the existing stability chair so that, while retaining its original training functions, it can provide differentiated auxiliary rotation and body support protection according to different training levels, especially providing stable support for the chest and abdomen of beginners after inversion, reducing training difficulty and improving safety and experience. Summary of the Invention

[0006] To address the aforementioned shortcomings of existing stability chairs used in inversion training, this invention provides a multi-mode Pilates stability chair suitable for inversion training. It can switch between beginner and advanced modes according to the user's training level, and provides stable support for the user's chest and abdomen in beginner mode, reducing the difficulty of inversion for beginners and enhancing the sense of safety during training.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A multi-mode Pilates stability bench suitable for inverted training includes an inverted support frame with an open front and hollow interior, a pedal assistance structure mounted on the front of the inverted support frame and rotatably hinged thereto, and armrests mounted on both sides of the inverted support frame for user hand support. The pedal assistance structure includes a mounting bracket and a pivot support assembly, which is rotatably hinged to the mounting bracket. Adjustable slide rails are provided on the inner walls of both sides of the inverted support frame, and protruding relief portions are formed in the upper middle part of both sides. The mounting bracket is slidably mounted within the adjustable slide rails, allowing the pivot support assembly to slide between the bottom of the inverted support frame and the protruding relief portions, corresponding to advanced and beginner modes. In beginner mode, the mounting bracket slides to the protruding relief section, and the toggle support component gains an increased rotation stroke, allowing it to continue rotating to the user's chest and abdomen to provide support after assisting the user in completing the inverted position, thus providing frontal limit protection for the user's inverted posture. In advanced mode, the mounting bracket is located at the bottom inside the inverted support frame, and the toggle support component, after flipping up, is limited by the inverted support frame and stops at a position that maintains a distance from the user's body, only providing rotation assistance.

[0008] Furthermore, a locking structure is provided between the mounting bracket and the adjusting slide rail. The locking structure includes an elastic pin that passes through the side wall of the mounting bracket and locking holes that are respectively opened on the upper and lower ends of the adjusting slide rail for the two modes. When the mounting bracket slides into place, the elastic pin automatically springs into the corresponding locking hole to lock, thereby ensuring that the pedal assist structure can be stably positioned in both modes.

[0009] Furthermore, the pedal-assisted structure employs differentiated flipping drive methods in advanced and beginner modes. In advanced mode, the swivel support assembly provides flipping assistance via a tension spring. One end of the spring is detachably connected to the swivel of the swivel support assembly, and the other end is detachably connected to the hanging ring of the inverted support frame. When the spring is at its original length, the swivel support assembly is in an upward-flipped state. Advanced users step on the swivel support assembly, stretching the spring to accumulate elastic potential energy. They can then use this elastic force in conjunction with their own muscle exertion to complete the inverted position, which helps improve muscle control. In beginner mode, the tension spring is removed, and an electrically driven rotating structure provides directional and stable flipping assistance, allowing beginners to complete the inverted position without manually adjusting their muscle exertion.

[0010] Furthermore, the towing support assembly includes two parallel and spaced towing support plates, with an electromagnetic control assembly between the two towing support plates for controlling the connection and separation of the two towing support plates, thereby meeting the needs of different training movements.

[0011] Furthermore, the electromagnetic control component includes an electromagnetically controlled telescopic connecting plate and protruding slots respectively located on the side walls of the two rotating support plates. When the telescopic connecting plate is electrically activated, it extends and engages with the two protruding slots, connecting the two rotating support plates into one unit to achieve synchronous movement, ensuring that the user's legs rotate upwards synchronously and the center of gravity remains stable. When the connection is disconnected, the two rotating support plates can rotate independently, allowing the user to perform cross-stepping training with both legs in advanced mode, enriching the training movements.

[0012] Furthermore, an electric rotating structure is provided between the two swivel support plates. The electric rotating structure is coaxially connected to the electromagnetic control component to synchronously transmit the rotation driving force to the two swivel support plates, ensuring that the flipping action on both sides is consistent in novice mode.

[0013] Furthermore, the electric rotation structure is equipped with two control switches for forward and reverse rotation, and the electromagnetic control component is equipped with one control switch. The three control switches are located on the handrail and in a convenient position for the thumb to press, so that the user can operate them instantly without letting go during inverted training.

[0014] Furthermore, each swivel support plate is equipped with a length adjustment structure, which includes a support sleeve and a sliding support rod that make up the swivel support plate. The two are adjusted and locked in length through multiple adjustment holes and locking pins. The end of the sliding support rod is equipped with a flexible pad for supporting the user's feet, so that this stable chair can be adapted to users of different heights.

[0015] Furthermore, the locking pin is integrated with the hanging shaft. By adjusting the insertion position of the locking pin, the tension length of the tension spring between the hanging shaft and the hanging ring can be adjusted simultaneously, realizing the linkage between length adjustment and elasticity adjustment. Moreover, both the support sleeve and the sliding support rod are provided with multiple adjustment holes, so that they have multiple sets of aligned adjustment hole combinations, ensuring that even if the position of the locking pin is adjusted, the adjustable length range of the towing support plate will not be affected.

[0016] Furthermore, the base plate of the inverted support frame extends forward to form a first support section, which is used to provide support for the transfer support assembly in advanced mode. The end of the first support section exceeds the maximum adjustable length of the transfer support assembly to increase the support area during the inverted preparation stage. The end of the adjusting slide rail located at the protruding clearance section extends forward horizontally to form a second support section, which is used to provide support for the transfer support assembly in novice mode.

[0017] Furthermore, a limit platform is provided at the junction of the second support and the downward-sloping adjustment slide rail to prevent the automatic downward sliding of the transfer support assembly and ensure its flipping stability in novice mode.

[0018] Furthermore, a retractable baffle is provided on the rear side of the inverted support frame to support the user's back. This baffle works in conjunction with the rotating support component on the front side of the user to provide limiting protection both in front of and behind the user, preventing the inverted position from becoming unstable and tipping over.

[0019] The present invention also provides a method for using the above-mentioned multi-mode Pilates stability chair, including a beginner mode training method and an advanced mode training method.

[0020] The beginner training method includes the following steps: Slide the mounting bracket along the adjusting rail to the protruding clearance part and lock it; adjust the length of the support assembly according to the user's height; the user holds the handrail, inverts their head and upper limbs on the upper end of the inverted support frame, and places their feet on the end of the support assembly away from the hinge to complete the inverted preparatory action; activate the electromagnetic control component to connect the two support plates into one unit; activate the electric rotation structure to synchronously drive the two support plates to flip upwards, assisting the user in completing the inverted position; keep the electric rotation structure running, allowing the support assembly to continue rotating along the original trajectory until it reaches the user's chest and abdomen to form support, then stop the electric rotation structure; at the end of the training, the user rolls down and places their feet on the flexible mat, then activates the electric rotation structure to reverse, returning the support assembly to its original training position.

[0021] The advanced training method includes the following steps: slide the mounting bracket along the adjusting slide rail to the bottom of the inverted support frame and lock it; connect the tension spring between the hanging shaft of the rotating support component and the hanging ring of the inverted support frame; the user completes the inverted preparatory action, steps on the rotating support component to stretch the tension spring to accumulate elastic potential energy, and uses the tension spring force in conjunction with the user's own muscle force to flip upward and complete the inverted position; the user can choose whether to activate the electromagnetic control component according to training needs. When the connection is disconnected, the independent rotation of the two rotating support plates can be used to perform cross-stepping training with both legs.

[0022] Compared with the prior art, the present invention has the following beneficial effects: Firstly, by setting an adjustable slide rail and a protruding clearance part on the inverted support frame, the pedal assist structure can slide and switch between two positions, realizing flexible switching between beginner and advanced modes, so that the same stable pedal chair can meet the inverted training needs of users with different training levels.

[0023] Secondly, in beginner mode, the support component can rotate to the user's chest and abdomen to form a front limit protection. On the one hand, it prevents beginners from tilting forward and falling over, reducing the difficulty of handstands. On the other hand, it provides psychological safety through physical contact, helping beginners to establish spatial awareness of body inversion and improve training experience and sustainability.

[0024] Third, the two modes adopt different flip-drive methods. The advanced mode uses a tension spring drive to train the user's own muscle control ability, while the beginner mode uses an electric drive to provide stable and reliable assistance, each matching the training characteristics and needs of the corresponding users.

[0025] Fourth, the toss support assembly adopts a structure of double toss support plates combined with electromagnetic control components, which can achieve synchronous movement to ensure stable flipping, and can also separate and move independently to expand training movements such as cross stepping, thus enriching the diversity of training modes.

[0026] Fifth, the integrated design of the locking pin and the hanging shaft in the length adjustment structure realizes the linkage between pedal length adjustment and tension spring force adjustment, which simplifies the adjustment operation and improves the ease of use.

Detailed Implementation

[0029] Example: This embodiment provides a multi-mode Pilates stability bench suitable for inverted training, applied to inverted Pilates training (such as...). Figure 1The diagram shown illustrates the use of an existing pedal chair. This design further improves upon the existing pedal chair structure, allowing for a beginner mode and an advanced mode based on the user's training level. The advanced mode can directly utilize the existing structure and usage pattern (e.g., ...). Figure 2 As shown), the improved structure for the beginner mode is the core design of this invention (which can be combined with...). Figure 4 refer to).

[0030] In beginner mode (e.g.) Figure 3 As shown, the pedal assist structure 20 of the stable chair expands its overall position adjustment function and ease of flipping and stability functions. This reduces the difficulty for beginners in inversions and, by adjusting the position of the structure, provides stable support for the chest and abdomen of the beginner after inversion. The physical blockage at the chest and abdomen alleviates the fear caused by loss of balance and helps beginners develop spatial awareness of inversion, ensuring that users can perform inversion training in a safe environment, thus improving training safety and experience. This invention also further improves the specific structure of the pedal assist structure 20 to make it suitable for users of different heights in both modes.

[0031] Specifically, refer to Figure 2 The chest and abdomen support stable footrest includes: The inverted support frame 10 is the main load-bearing component of the stable chair. It is a frame with an open front and hollow interior. The upper middle part of both sides has protruding relief parts 11 facing forward. Armrests 30 for hand support are also installed on both sides (see the hand support action for reference). Figure 1 ); The pedal assist structure 20 is used to provide upward flipping assistance in the first half of the inversion, shortening the stroke that requires relying entirely on one's own strength to invert, while overcoming the maximum resistance torque during the initial flip and reducing the difficulty of inversion; and after inversion, it can also provide stable support for the user's chest and abdomen, so as to improve the user's sense of security in the inverted state where they lose balance. This structure is installed in front of the inversion support frame 10 and includes a rotating hinged mounting bracket 21 and a swivel support assembly 22. The mounting bracket 21 is slidably mounted within the adjusting slide rails 12 on the two inner walls of the inverted support frame 10. This causes the rotating support assembly 22 to slide outwards and upwards from the inner bottom end of the inverted support frame 10 to the protruding relief portion 11. By adjusting the relative position of the rotating support assembly 22, its tilting angle is increased, allowing it to turn towards the user's chest and abdomen to provide support (e.g., ...). Figure 3 , Figure 4 As described above); and when the transfer support assembly 22 is located at the inner bottom end (as... Figure 2As shown), its rotation angle is limited, and it will collide with the inverted support frame 10 after flipping up. At this time, there is a certain space between the rotating support component 22 and the user's body; therefore, according to the two states mentioned above, there are also novice mode and advanced mode.

[0032] With the above structure, users can choose the appropriate mode according to their training level. If they are beginners, they can choose the novice mode. First, slide the pedal assist structure 20 to the protruding relief part 11, and then use the flipping assistance of the rotating support component 22 to achieve a handstand. After the handstand is completed, the rotating support component 22 continues to rotate to support the beginner's chest and abdomen, providing stable support. Therefore, on the one hand, it can prevent the beginner from falling forward and further reduce the difficulty of the handstand, and on the other hand, it can provide the beginner with a sense of psychological security and improve the experience. If they are advanced, they can choose the advanced mode, which simply means keeping the pedal assist structure 20 at the bottom. At this time, the rotating support component 22 only plays the role of assisting the flipping.

[0033] Based on the aforementioned structure, it can be seen that the position of the towing support component 22 and the requirements for flipping are different in the two modes. To address these differences, the flipping drive structure in the two modes is configured differently, as follows.

[0034] When selecting advanced mode, refer to Figure 5 The rotating support assembly 22 utilizes the elasticity of a tension spring (not shown in the figure) to provide assistance for the flipping motion. One end of the tension spring is detachably connected to the hanging shaft 231 of the rotating support assembly 22, and the other end is detachably connected to the hanging ring 232 of the inverted support frame 10. When it is at its original length, the rotating support assembly 22 is in an upward-flipped state. When the advanced user performs the preparatory action for the inverted position, that is, holding the handrail 30, the head and upper limbs are inverted on the upper part of the inverted support frame 10 (see reference). Figure 1 When the feet are placed on the end of the pivot support assembly 22 away from the hinge, the tension spring will be stretched, accumulating elastic potential energy. Advanced users can use this elastic potential energy to flip their lower limbs upward.

[0035] When beginner mode is selected, the tension spring can be removed, and an electric rotating structure 24 provides tilting assistance (e.g., Figure 2 , Figure 6 As shown), to ensure stable and reliable flipping assistance and precise control of the flipping angle (wherein the electric rotation structure is a commonly used existing structure, so its structure will not be described in detail in this embodiment).

[0036] The advantages of the aforementioned differentiated flip-drive settings are as follows: In the advanced mode, advanced users need to coordinate their own efforts and control the corresponding muscle groups to achieve a stable and smooth inversion while using the spring force to flip upwards. This helps advanced users strengthen their muscle control and improve training results. For beginners, it is usually difficult to control their own muscle force and to coordinate with the spring force to achieve an inversion. Therefore, in the beginner mode, the flip assistance is implemented with an electric control structure, which can provide a directional and stable upward flip assistance, reducing the difficulty of inversion for beginners. This helps beginners complete the inversion and improve their experience, cultivating a habit of continuous training.

[0037] To diversify training modes and expand training movements, the support component 22 is further configured, and its specific structure is as follows.

[0038] Referring to Figure 2, the transfer support assembly 22 includes two parallel and spaced transfer support plates 221, each transfer support plate 221 being provided with a hanging shaft 231 (e.g., ...). Figure 6 (as shown); and an electromagnetic control assembly 25 (which can be further combined) is also provided between the two aforementioned support plates 221. Figure 3 (Reference), used to control whether the two rotating support plates 221 are connected or not, and is coaxially connected with the electric rotating structure 24 so as to synchronously transmit the rotation driving force to the two rotating support plates 221. Correspondingly, the electric rotating structure 24 is also arranged between the two rotating support plates 221.

[0039] Among them, reference Figure 5 , Figure 6 The electromagnetic control component 25 includes an electromagnetically controlled telescopic connecting plate 251 and protruding slots 252 respectively provided on the side walls of the two rotating support plates 221. When the telescopic connecting plate 251 is electrically activated, it extends and engages with the two protruding slots 252, thereby connecting the two rotating support plates 221 together and ensuring that the two rotating support plates 221 can move synchronously. Therefore, it stably and reliably assists the user's two legs to flip upward synchronously, keeping the user's center of gravity stable and preventing tipping.

[0040] When the connection between the telescopic connecting plate 251 and the protruding slot 252 is disconnected, the two rotating support plates 221 can return to a state of relatively independent rotation (see reference). Figure 6 This allows users to perform cross-stepping movements of both legs during training using the two pivot support plates 221, but this type of exercise training is only applicable to the advanced mode.

[0041] Furthermore, the aforementioned electric rotation structure 24 requires two control switches, one for forward rotation and the other for reverse rotation, and the electromagnetic control component 25 requires one control switch. These three control switches are located on the two handrails 30 and in a convenient position for thumb pressing, so that users can control them in real time during training (none of the three control switches are shown in the figure).

[0042] Preferably, to make this stable chair suitable for users of different heights, the swivel support plate 221 has a length adjustment structure 26 (e.g., Figure 2 As shown), this allows adjustment of the distance between the user's feet and head during the inverted preparatory position. Specifically, refer to... Figure 6 The length adjustment structure 26 includes a support sleeve 261 and a sliding support rod 262 that make up the pivot support plate 221. The two are adjusted and locked through multiple adjustment holes 263 and locking pins 264. The end of the sliding support rod 262 has a flexible pad 27 (e.g., Figure 6 As shown, it is supported by the user's feet.

[0043] Further, refer to Figure 6 The locking pin 264 is integrated with the hanging shaft 231 to facilitate the adjustment of the tension length of the tension spring between the hanging shaft 231 and the hanging ring 232 by adjusting the position of the locking pin 264. At the same time, both the support sleeve 261 and the sliding support rod 262 are provided with multiple adjustment holes 263 so that they have multiple sets of aligned adjustment holes 263. Even if the insertion position of the locking pin 264 is adjusted to adjust the tension spring force, it will not affect the adjustment length of the rotating support plate 221.

[0044] The present invention also includes the following structure to further improve the structure of this stable chair.

[0045] To ensure that the transfer support assembly 22 can be stably held at both ends of the adjusting slide rail 12 in both modes, a locking structure 40 is also provided between the mounting bracket 21 and the two adjusting slide rails 12 (e.g., Figure 2 (As shown), Reference Figure 3 , Figure 5 It includes a detachable and pluggable resilient pin 41 and a locking hole 42, wherein the resilient pin 41 passes through the side wall of the mounting bracket 21 (e.g., Figure 6 As shown, the locking holes 42 are respectively opened on the sides of the upper and lower ends of the adjusting slide rail 12 for the two modes. Therefore, when it is necessary to change the training mode, the user can pull out the elastic pin 41 to disengage it from the locking hole 42, and then slide it along the adjusting slide rail 12 to the position of the desired mode. When it reaches the corresponding position, the elastic pin 41 automatically springs into the locking hole 42 due to its elasticity, and locks it again, thereby ensuring the stable installation of the towing support assembly 22 and the inverted support frame 10.

[0046] Regardless of the mode, the transfer support assembly 22 needs to support part of the user's weight. In order to improve the reliability and stability of its support and extend its service life, the lower end of the transfer support assembly 22 has a support part, the specific structure of which is as follows.

[0047] The base plate of the inverted support frame 10 extends forward to form the first support portion 13 for the support assembly 22 in the advanced mode (e.g., ...). Figure 3 As shown), the end of the first support part 13 extends beyond the longest length of the transfer support assembly 22 to maximize the support area during the inversion preparation stage and ensure support stability. The end of the adjusting slide rail 12 located at the protruding relief portion 11 extends horizontally forward to form a second support portion 121 for the towing support assembly 22 in novice mode (e.g., ...). Figure 5 As shown), and a limiting platform 122 is provided at its intersection with the adjusting slide rail 12 at a downward angle (as shown). Figure 5 As shown in the figure, it can prevent the automatic sliding of the transfer support assembly 22 and ensure its flipping stability.

[0048] Preferably, a retractable baffle (not shown in the figure) can also be provided on the rear side of the inverted support frame 10, or the rear side of the stable chair can be leaned against the wall to support the user's back. At the same time, it can cooperate with the rotating support component 22 on the front side of the user to form a blocking protection in front of and behind the user, preventing the user from being unstable and falling over, improving the safety protection effect, and also improving the user's sense of security during training.

[0049] The working process of this embodiment is as follows: When the user is a beginner, they can choose the beginner mode and refer to the tutorial. Figure 3 , Figure 4 First, manually adjust the position of the pedal assist structure 20, moving it to the second support part 121 of the adjusting slide rail 12 and locking it automatically. At the same time, adjust the length of the rotating support plate 221 to suit your needs. Then, the beginner begins the preparatory movement for the handstand and presses the corresponding control switches in sequence. First, the electromagnetic control component 25 is activated, connecting the two rotating support plates 221 together. Then, the electric rotating structure 24 is activated, synchronously driving the two rotating support plates 221 to flip upwards together, providing assistance to help the beginner achieve the handstand. After the handstand is completed, the electric rotating structure 24 continues to output power, causing the two rotating support plates 221 to continue rotating along the original trajectory until they reach the beginner's chest and abdomen to provide stable support. Then, the electric rotating structure 24 is stopped. When the training is over and you need to return to the original position, the user must first roll down and place their feet on the flexible pad 27, and then activate another control switch of the electric rotating structure 24 to reverse it back to the training position in beginner mode. If the user is an advanced user, they can choose the advanced mode, see below. Figure 2At this time, the pedal assist structure 20 is adjusted to the bottom of the adjustment slide rail 12, and the tension spring is connected to the hanging shaft 231 and the hanging ring 232. Then, prepare for the inverted preparatory action. With the help of the tension spring, the advanced user can flip upward. During this process, the user can also control whether to activate the electromagnetic control component 25 according to their own training needs.
