Description

Technical Field

[0001] The present invention belongs to the technical field of sports equipment, and in particular to a Pilates fitness equipment capable of multi-directional training and full-capability flexion and extension, and an auxiliary device and processing method for covering its skin. Background Technique

[0002] The Pilates stability chair and the Pilates wooden ladder barrel are two popular Pilates training equipment, each focusing on different training focuses and effects.

[0003] The stability chair is mainly used for training the lower limbs and core muscle groups. Attached Figure 1 Shown is a common stability chair 01, which includes components such as a seat 011, a pedal 012, an elastic device 013, and an armrest 014. The seat includes two side plates and a top plate; the rear of the pedal is connected to the bottoms of the two side plates, and the front extends to the front of the seat; the elastic device is connected between the rear bracket of the seat and the pedal; there are insertion tubes on the outer sides of the two side plates, and the armrests are inserted into the insertion tubes. In actual use of the stability chair, if the user is a child, pregnant woman, or elderly person, then generally the stability needs to be further improved, and the general way to improve it is to connect and fix it to the ground.

[0004] Attached Figure 2 Shown is a common Pilates wooden ladder barrel 02, which includes components such as a fixed frame 021, a ladder frame 022, and a lying barrel assembly 023. The lying barrel assembly 023 includes a lying barrel 024 and two side plates 025 that straddle the lying barrel 024. The lying barrel is a semi-cylinder cut along the axis of the cylinder, and the side with the arc surface faces upward. The arc surface layer of the lying barrel is a flexible structure, which is composed of a foaming material adhered to the arc surface skeleton and leather or elastic fabric that covers and fixes the foaming material. The characteristic of the wooden ladder barrel is that it is a fixed structure as a whole, with a large volume and weight and good stability. It is mainly used for training the whole body strength, flexibility, and balance ability.

[0005] Based on the basic structures of Attached Figure 1 and Attached Figure 2 The Chinese utility model patent publication number CN215310019U discloses a sports rehabilitation correction ladder barrel chair. A sitting and pedaling mechanism is arranged on one side between the climbing ladder and the lying barrel for users to step on for abdominal and leg exercises. This sitting and pedaling mechanism is actually the structure of a stability chair, but in terms of function, due to the user's body position being restricted by the ladder frame 022, it cannot achieve all the original training functions of the stability chair.

[0006] Inspired by the above, we further studied and analyzed the structures of the stable step chair and the wooden ladder bucket, and combined them better to make up for their respective deficiencies, and optimized and improved a more reasonable Pilates combination exercise equipment. Our research results show that by integrating the stable step chair and the wooden ladder bucket, more diverse training methods and more comprehensive physical exercises can be achieved.

[0007] On the other hand, for the production of the lying bucket 024, a large amount of manual intervention is required in the existing production line. This is because when the leather or fabric on the surface of the lying bucket wraps and fixes the foaming material, manual workers need to constantly stretch and tighten the surface layer, and at the same time use air nails to connect the leather or fabric to the skeleton point by point. During the process, the operators also need to frequently change the position of the lying bucket 024 to fix it point by point by symmetrically tightening the leather or fabric and taking into account whether there are wrinkles until the whole is completed. This production method has a large labor intensity and low production efficiency. Also, due to the existence of human uncertain factors, there are easily defects in the aesthetic effect. Summary of the Invention

[0008] In view of the above problems, the present invention provides a new type of Pilates fitness equipment, which has an improved stable step chair that can slide and lock and an expandable and telescopic chair, providing users with more fitness options, enhancing the functionality, adaptability and adjustability of the equipment, and making Pilates practice more personalized, flexible and comprehensive.

[0009] The invention purpose of the present invention is realized through the following technical solutions: a Pilates fitness equipment, comprising: a fixing frame that can be stably placed on the ground to support a user sitting or standing on the upper part; the fixing frame includes two parallel bottom beams;

[0010] A climbing rod frame fixedly connected to one end of the fixing frame and extending upward; the fitness equipment further includes an improved stable step chair that is slidably and lockably arranged at the other end of the fixing frame; the improved stable step chair includes two side plates that can slide and lock relative to the two bottom beams respectively, a chair surface installed at the upper ends of the two side plates, and the side plates and the chair surface together form a box-shaped frame structure. The improved stable step chair further includes an expandable and telescopic chair that can slide and lock relative to the sliding direction of the side plates and is hidden or exposed outside the box-shaped frame structure, a pair of separate pedals installed on the box-shaped frame structure and an elastic device that provides tension to the pedals;

[0011] The expandable and telescopic chair is entirely located above the pedals. When the expandable and telescopic chair slides away from the climbing rod frame side, it will press the pedals to the unfolded horizontal state. At this time, the pedals and the elastic device are basically covered by the expandable and telescopic chair. In this way, it gives people a simple and beautiful tactile feedback. At the same time, users can combine different training modes through the expandable and telescopic chair and the improved stable step chair.

[0012] This Pilates fitness equipment mainly includes a fixed frame, a climbing pole frame, and an improved stable stepping chair. The feature lies in that an improved stable stepping chair which can slide and be locked is added at the other end of the fixed frame. This design enables users to adjust the position of the improved stable stepping chair according to their personal fitness needs, thus providing users with more flexible and diverse fitness options. Compared with the prior art, this design can improve the adaptability of the Pilates fitness equipment and meet the needs of more users.

[0013] Preferably, the elastic device is one or more elastic members. The claim states that the elastic device is one or more elastic members. This means that the tension of the pedal can be adjusted by increasing or decreasing the number of elastic members to adapt to the physical constitutions and fitness needs of different users. Such a design enhances the adjustability of the equipment and is more personalized compared with the prior art.

[0014] Preferably, an improved lying bucket is stacked and arranged on the improved stable stepping chair; the improved lying bucket includes a skeleton in the shape of a semi-cylinder cut along the axis of the cylinder, a flexible material adhered to the arc surface of the skeleton, an elastic surface layer that wraps the flexible material and is fixed to the skeleton, a sealing plate fixed to the bottom surface of the skeleton, and first, second, third, and fourth enclosing plates serving as the surface layer on the side surface of the skeleton. The sealing plate and each enclosing plate form a frame structure, and the inner empty shape and size of the structure are consistent with the shape and size of the periphery of the chair surface. An improved lying bucket is stacked and arranged on the improved stable stepping chair. Such a design enhances the functionality of the equipment. It can not only perform traditional Pilates exercises but also carry out more fitness activities through the lying bucket. Compared with the prior art, this design is more comprehensive and increases the usage scenarios of the equipment.

[0015] The present invention also provides a leather covering auxiliary device which, through the cooperation of various specific mechanisms, can replace manual operations for feeding, cutting, stretching, wrapping, positioning, and locking the surface layer of the semi-finished Pilates lying bucket, greatly improving the production efficiency and product quality of the Pilates lying bucket.

[0016] The auxiliary device includes:

[0017] A translation mechanism for carrying multiple functional components, which includes two parallel guide rails and an installation platform slidably engaged with the two guide rails through multiple sliders;

[0018] A surface layer feeding mechanism to replace manual laying, which includes two bearing frames and two feeding frames that are fixed on the installation platform and are opposed to each other with respect to the center, a feeding roller rotatably connected between the two bearing frames, and multiple transition rollers rotatably connected between the two feeding frames, and one of the transition rollers is connected to a power motor;

[0019] A surface layer cutting mechanism that replaces manual cutting. It includes cylinders fixedly installed on two material feeding racks respectively. The end of the free telescopic end of the cylinder has a mounting seat. A profile guide rail fixedly arranged between the two mounting seats, and a sliding tool holder installed on the profile guide rail;

[0020] A locking and positioning mechanism for locking the semi-finished product with the covering not fixed. It includes a clamping component. The clamping component includes a fixed clamping block, and one movable clamping block on each side of the fixed clamping block. Both movable clamping blocks are hinged to the frame of the base platform on the side adjacent to the fixed clamping block. It also includes a first power cylinder and a second power cylinder that independently push the movable clamping blocks to rotate respectively;

[0021] A stretching and covering mechanism for flattening and covering the cut elastic surface layer as necessary. It includes two hinge frames respectively coaxially hinged to one of the movable clamping blocks on both sides of the fixed clamping block. A telescopic stop at the end far from the hinge on each hinge frame. Two stretching cylinders with the body fixedly installed below the hinge frame and the telescopic parts fixedly connected to the telescopic stop. A third power cylinder and a fourth power cylinder that respectively push the two hinge frames to rotate. A surface layer clamping piece hinged to the side far from the fixed clamping block of each telescopic stop. A clamping cylinder with the body fixed at the free telescopic end of the stretching cylinder and the telescopic rod hinged to the surface layer clamping piece;

[0022] For this auxiliary device, first, the translation mechanism carries the functional component to move on the guide rail and sends the functional component to the specified working position; the surface layer feeding mechanism takes over the work, and under the drive of the power motor, the surface layer is smoothly laid on the locking and positioning mechanism via the feeding roller and multiple transition rollers;

[0023] Then, the surface layer cutting mechanism works. The cylinder pushes the sliding tool holder to move along the profile guide rail to precisely cut the surface layer;

[0024] Then, the semi-finished product is placed into the locking and positioning mechanism, and the stretching and covering mechanism starts to work. The two surface layer clamping pieces clamp the end of the surface layer. The two stretching cylinders stretch the surface layer. Finally, the hinge frame rotates around the semi-finished product to flatten and cover the elastic surface layer, making it perfectly fit on the semi-finished product. Finally, the surface layer and the semi-finished product are locked together through the clamping component to ensure its stability in subsequent operations.

[0025] It has an automated surface layer feeding mechanism, surface layer cutting mechanism, locking and positioning mechanism, and stretching and covering mechanism, which can automatically complete steps such as surface layer feeding, cutting, semi-finished product locking, and flattening and covering, reducing production complexity and labor intensity, and improving production efficiency and product quality.

[0026] Preferably, the working surfaces of the two movable clamping blocks and the fixed clamping block are concave arc surfaces with the same radian as that of the lying barrel. The working surfaces of the movable clamping blocks and the fixed clamping block being concave arc surfaces with the same radian as that of the lying barrel can ensure that the leather covering auxiliary device perfectly matches the radian of the improved lying barrel, improving the accuracy of locking and positioning and making the product quality more stable.

[0027] Preferably, a guiding mechanism is provided between the hinge frame and the telescopic stop. The provision of the guiding mechanism between the hinge frame and the telescopic stop enables the stretching and covering mechanism to work more smoothly and precisely, improving the effect of stretching and covering.

[0028] Preferably, the surface layer cutting mechanism further includes a cutting power transmission system for driving the sliding tool holder to move along the profile guide rail. Driving the sliding tool holder to move along the profile guide rail through the cutting power transmission system improves the efficiency and accuracy of surface layer cutting.

[0029] Preferably, the translation mechanism further includes a translation power transmission system for driving the installation platform to move along the guide rail; the translation power transmission system includes racks arranged adjacent to each other on each guide rail, gears meshing with the racks, bevel gear sets coaxially arranged with the gears, a synchronous shaft connecting the two bevel gear sets, and a driving motor fixed on the installation platform and belt-drivably connected to the synchronous shaft. The translation mechanism including the translation power transmission system for driving the installation platform to move along the guide rail makes the movement of the translation mechanism more precise and smooth, contributing to improving the working efficiency and accuracy of the entire leather covering auxiliary device.

[0030] The present invention also provides a lifting mechanism, which realizes the precise grasping and handling of semi-finished products during the surface layer feeding process through the cooperation of components such as a gear set, a bent arm, a pry bar, and a lifting cylinder, thereby greatly improving production efficiency and operation accuracy and reducing manual operation and related risks.

[0031] The lifting mechanism includes: gear sets respectively fixedly installed on the outer sides of each feeding rack, a bent arm fixedly connected to one of the gears at one end, a sector gear with an extension arm on the other gear, a pry bar fixedly connected to the extension arms of the two sector gears at both ends, a lifting cylinder with a base fixed on the installation platform and a telescopic free end rotatably sleeved on the pry bar through a support, the other end of the bent arm being a free end, and a propulsion assembly being provided on the free ends of both bent arms. The propulsion assembly includes a seat body, a propulsion cylinder installed in the seat body, and an insertion block fixedly connected to the free end of the telescopic rod of the propulsion cylinder. Such a mechanism includes components such as a gear set, a bent arm, a pry bar, and a lifting cylinder, forming an efficient lifting system for grasping and handling semi-finished products during the surface layer feeding process. This structure effectively improves production efficiency and operation accuracy and reduces manual operation and related risks.

[0032] Preferably, the shape of the insertion block matches the hole of the object to be grasped. Compared with the prior art, the following beneficial effects are mainly achieved: the shape of the insertion block matches the hole of the object to be grasped, which can ensure better stability and control of the object during grasping, reduce the sliding and dropping of the object, and improve the safety and accuracy of handling.

[0033] Preferably, the insertion block is made into a replaceable module. The insertion block being made into a replaceable module allows different insertion blocks to be replaced according to different object types and requirements, improving the applicability and flexibility of the lifting mechanism.

[0034] Preferably, the lifting mechanism adopts a lever-type prying lifting structure with gear transmission, which can achieve high-efficiency lifting with a short stroke. The lifting mechanism adopting a lever-type prying lifting structure with gear transmission can achieve high-efficiency lifting with a short stroke, improve the working efficiency of the lifting mechanism, reduce energy consumption, and save resources.

[0035] The present invention also provides a propulsion assembly, which is an optimization of the foregoing propulsion assembly, used to maintain the center-of-gravity balance of the semi-finished product throughout the process of picking up, lifting, and finally putting down, thereby enhancing the stability and accuracy of the lifting mechanism when handling objects with complex shapes such as arc surfaces.

[0036] The propulsion assembly includes: a seat body, a propulsion cylinder fixedly installed in the seat body, a propulsion frame slidably installed in the seat body. The propulsion frame includes an external connection plate connected to the free end of the telescopic rod body of the propulsion cylinder, a guide rod integrally and tightly sliding in the seat body with one end fixedly connected to the external connection plate, and an internal connection plate fixedly connected to the other end of the guide rod; a fixed shaft is fixedly provided on the side of the internal connection plate away from the external connection plate, and a connecting seat is tightly rotatably sleeved on the free end of the fixed shaft. Compared with the prior art, the following beneficial effects are mainly achieved:

[0037] The propulsion assembly includes a seat body, a propulsion cylinder, a propulsion frame, and various connecting plates and fixed shafts, etc., which makes the structure of the propulsion assembly more stable and the work more reliable. Especially the propulsion frame can be connected to the free end of the telescopic rod body of the propulsion cylinder, making the propulsion action smoother and the work efficiency higher.

[0038] Preferably, a limiting groove is provided on the bottom surface of the connecting seat facing the internal connection plate, and a stop rod entering the limiting groove is provided in the fixed shaft. The range within which the connecting seat can rotate is the active range between the stop rod and the limiting groove. The bottom surface of the connecting seat is provided with a limiting groove, and a stop rod entering the limiting groove is provided in the fixed shaft, which limits the rotation range of the connecting seat, thereby avoiding excessive rotation of the connecting seat and enhancing safety and reliability.

[0039] Preferably, the limiting groove is arc-shaped. The arc-shaped limiting groove can limit the rotation range of the connecting seat while making the rotation of the connecting seat smoother, reducing the impact and damage caused by sudden obstruction, and further improving the safety and service life of the equipment.

[0040] Preferably, a return torsion spring is arranged between the bottom surface of the connecting seat facing the inner connecting plate and the inner connecting plate. A return torsion spring is arranged between the bottom surface of the connecting seat and the inner connecting plate, which can make the connecting seat automatically reset after completing the action, and also ensure the continuous and stable operation of the equipment.

[0041] Preferably, when the return torsion spring is preset to be unloaded, the extending block installed on the connecting seat is limited to a unified initial position by the torsion of the torsion spring and the cooperation of the limiting groove and the rod. When the torsion spring is preset to be unloaded, the extending block installed on the connecting seat is limited to a unified initial position by the torsion of the torsion spring and the cooperation of the limiting groove and the rod. This can ensure that each operation starts from the same initial position, guarantee the working accuracy of the equipment, and reduce the risk of damage to the equipment caused by operation errors.

[0042] In summary, the design of this propulsion assembly enables the semi-finished product to be in a stable state of center of gravity all the time by the preset torsion of the return torsion spring counteracting the torsional force generated by the change of the center of gravity even when the center of gravity of the semi-finished product changes due to the rotation of the bent arm during lifting, thus improving the stability and accuracy of the lifting process of the semi-finished product.

[0043] The present invention also provides an operation method for an auxiliary assembly line for covering leather, which details a comprehensive working process including steps such as surface layer feeding, cutting, stretching, handling, covering, and fixing. This makes the covering leather processing more automated and efficient, reducing manual operation and potential errors.

[0044] Including the following steps:

[0045] a. Pre-control the two movable holding blocks and the two hinge frames to the flattened state through corresponding power sources, and control the surface layer clamping member to the open state through the corresponding power source;

[0046] b. The translation mechanism moves, driving the surface layer feeding mechanism to the telescopic gear at the far end. The power motor starts feeding, and the starting head of the elastic surface layer is lowered into the clamping area of the surface layer clamping member. The power motor stops, and the clamping cylinder starts, and the surface layer clamping member clamps the starting head of the elastic surface layer;

[0047] c. The translation mechanism moves to the telescopic gear on the other side. At the same time, the power motor starts feeding again, and the elastic surface layer lays the surface layer along the traveling route. The translation mechanism moves until it is below the telescopic gear on the other side;

[0048] The d-surface layer cutting mechanism is activated to cut the elastic surface layer. After cutting, the material end automatically falls into the clamping range of the surface layer clamping piece on this side, and the clamping cylinder is activated. The surface layer clamping piece clamps the material end of the elastic surface layer.

[0049] e The two stretching cylinders on both sides are simultaneously activated to stretch outwards, and the elastic surface layer to be covered with skin is stretched and flattened.

[0050] f The translation mechanism moves to one side of the input semi-finished product, and the lifting mechanism is activated to carry the semi-finished product into the locking and positioning mechanism.

[0051] g The two hinge frames rotate upwards around the semi-finished product under the push of the corresponding power cylinders until the semi-finished product is completely covered.

[0052] h The pressing cylinder is activated, and the pressing beam plate presses the semi-finished product from top to bottom. The two movable clamping blocks gradually press the semi-finished product covered by the surface layer from both sides under the push of the corresponding power cylinders, then release the two surface layer clamping pieces, and reset the two hinge frames.

[0053] i Use fixing parts such as staples to connect the elastic surface layer to the skeleton. After completion, cut off the excess material head. Finally, release the pressing beam plate and the movable clamping blocks, and the translation mechanism drives the lifting mechanism to carry the semi-finished product with the surface layer covered to the output of the loading and unloading conveyor assembly.

[0054] Preferably, in step b, the translation mechanism is driven by the translation power transmission system to move to below the corresponding telescopic gear. This claim clearly defines the movement of the translation mechanism driven by the translation power transmission system in step b, and describes the operation process of the equipment in more detail, which helps to improve the operation accuracy and efficiency.

[0055] Preferably, in step d, after the surface layer cutting mechanism cuts the elastic surface layer, the material end automatically falls into the clamping range of the corresponding surface layer clamping piece, and then the clamping cylinder is activated to make the surface layer clamping piece clamp the material end of the elastic surface layer. The cut surface layer can automatically fall into the corresponding surface layer clamping piece and then be clamped by the clamping cylinder. This design makes the operation smoother and more efficient, and improves the processing speed.

[0056] Preferably, in step a, the two movable clamping blocks and the two hinge frames are controlled to a flattened state by the corresponding power sources, and their positions are detected and confirmed by sensors. Pre-controlling and detecting the positions of the two movable clamping blocks and the two hinge frames can ensure the normal operation of the equipment and reduce the possibility of equipment failures and errors.

[0057] Preferably, in step i, the connection between the elastic surface layer and the skeleton is not limited to using staples, and may also include using glue, heat fusion welding, soldering or other appropriate fixing methods. In addition to using staples, other methods such as glue and soldering can also be used to fix the elastic surface layer and the skeleton, increasing the flexibility and applicability of the operation.

[0058] In summary, the present invention has the following advantages compared with the prior art:

[0059] 1. Efficient automated operation: The entire system performs automated covering processing through precise mechanical devices and clear operation steps. From the placement, cutting, unfolding of the fabric to the final covering and fixing, this process is executed precisely and efficiently, greatly improving production efficiency and quality;

[0060] 2. Flexible and diverse processing methods: Not only can staples be used to fix the elastic surface layer and the skeleton, but other methods such as glue and soldering can also be used, which increases the flexibility and adaptability of the work;

[0061] 3. High precision and quality: Through precise mechanical design and automated operation, the accuracy and quality of the covering processing are ensured. For example, precise translation mechanisms, cutting mechanisms, lifting mechanisms, and detailed propulsion component designs all contribute to improving the accuracy and quality of the covering processing;

[0062] 4. Reducing errors and failures: Through the detection of preset positions and actions, errors can be detected and corrected in a timely manner, reducing the possibility of equipment failures and operation mistakes, and improving the stability and reliability of the equipment;

[0063] 5. Strong adaptability: By adopting a detachable module design, it can easily handle workpieces with different hole shapes, improving the adaptability of the equipment.

[0064] Generally speaking, this invention provides an efficient, precise, stable and flexible covering processing solution, which helps to improve production efficiency and product quality, reduce the risk of errors and failures, and improve the adaptability and flexibility of the equipment.

Detailed implementation mode

[0083] The following describes the present invention in further detail with reference to the embodiments shown in the drawings, referring to Figure 1-16 All the drawings;

[0084] Embodiment 1

[0085] Figure 3 The combined multi-functional Pilates fitness equipment 100 of the present invention is shown, which provides users with more choices of training methods.

[0086] The fitness equipment 100 includes:

[0087] 1. A fixed frame 110 that can be stably placed on the ground to support a user sitting or standing on the upper part. The fixed frame 110 includes two parallel bottom beams 111. To increase the overall stability, (optionally) a strengthening cross beam is connected between the two parallel bottom beams 111;

[0088] 2. A climbing pole frame 120 fixedly connected to one end of the fixed frame 110 and extending upward;

[0089] 3. An improved stable stepping chair 210 slidably and lockably arranged at the other end of the fixed frame 110. The improved stable stepping chair 210 includes two side plates 211 that can slide and lock relative to the two bottom beams 111 respectively, a chair surface 212 installed at the upper ends of the two side plates 211, and the side plates 211 and the chair surface 212 together form a box-shaped frame structure. The improved stable stepping chair 210 further includes an expandable telescopic chair 300 that can slide and lock relative to the sliding direction of the side plates 211 and is hidden or exposed outside the box-shaped frame structure, as well as a pair of separate pedals 213 installed on the box-shaped frame structure and an elastic device 214 that provides tension to the pedals 213, and a vertical armrest 215 installed on each of the two side plates 211.

[0090] The expandable telescopic chair 300 is entirely located above the pedals 213. The specific positioning and connection method of the pedals 213 and the elastic device 214 are the same as the commonly used structures in the prior art, that is, each pedal is connected to the free distal end of a pivot arm, and the other end of the pivot arm is rotatably connected to the box-shaped frame structure using a self-lubricating bearing hinge for fixation to achieve smooth operation and rotation of the arm. The elastic device 214 can be one or more elastic members, such as a helical spring, and one end of each spring is connected to the pivot arm through a saddle or eye strap, a hook-eye bolt, or a knob anchor.

[0091] When the expandable telescopic chair 300 slides towards the side away from the climbing pole frame 120, it will press the pedals 213 to the unfolded horizontal state. At this time, the pedals 213 and the elastic device 214 are basically covered by the expandable telescopic chair 300, which gives a simple and beautiful tactile feedback. This is usually the normal state when not using the stepping exercise. Another advantage of this is that users can combine different training modes through the expandable telescopic chair 300 and the improved lying bucket 220 or the improved stable stepping chair 210. In addition, the expandable telescopic chair 300 can also be taken out and placed on the side close to the climbing pole frame 120, or directly slid to this side to be used in combination with the improved lying bucket 220. The difference is that the way of taking out can adjust the direction of the expandable telescopic chair 300.

[0092] 4. An improved lying bucket 220 is stacked and set on the improved stable stepping chair 210. The improved lying bucket 220 refers to Figure 5, including a skeleton 221 in the shape of a semi-cylinder cut along the axis of the cylinder, a flexible material 222 adhered to the arc surface of the skeleton 221, and an elastic surface layer 223 that wraps the flexible material 222 and is fixed to the skeleton 221. The elastic surface layer 223 is not shown in Figure 5 and the elastic surface layer 223 can be leather or a fabric with a certain elasticity. The improved lying bucket 220 further includes a sealing plate 224 fixedly connected to the bottom surface of the skeleton and first, second, third, and fourth enclosing plates 225, 226, 227, and 228 serving as surface layers on the side of the skeleton; the sealing plate 224 and each enclosing plate form a frame structure, and the inner hollow shape and size of the structure are consistent with the periphery of the chair surface 212 to be stable and firm when the two are sleeved. At the same time, each enclosing plate also covers the fixing parts such as staples that connect the elastic surface layer 223 and the skeleton 221 to achieve an aesthetic effect.

[0093] The combined multifunctional Pilates fitness equipment 100 has the following advantages compared with the existing stable stepping chair and wooden ladder bucket:

[0094] 1. Integration and diversity: The overall design integrates the functions of the stable stepping chair and the wooden ladder bucket, combines the two, and provides users with more choices of training methods. This enhances the diversity and application scope of the fitness equipment, enabling users to carry out more comprehensive and diverse training.

[0095] 2. Improved design of the stable stepping chair: Due to the addition of the expandable telescopic chair 300, the stable stepping chair can become simple and beautiful when not in use for stepping exercises, and different training modes can be combined. This enhances the practicality and aesthetics of the stable stepping chair.

[0096] 3. Flexibility: The expandable telescopic chair 300 can be moved or removed and can be used in combination with the improved lying bucket 220 or the improved stable stepping chair 210. The improved lying bucket 220 can be stacked on the improved stable stepping chair 210 or removed. The two detachable combination methods provide more usage possibilities and flexibility.

[0097] 4. Stability: The improved stable stepping chair 210 forms a connection with the fixed frame 110, increasing the overall stability, making the equipment more stable and suitable for various people to use.

[0098] 5. Improved design of the lying bucket: The height of the improved lying bucket 220 is reduced by nearly half compared with the original lying bucket 024. Such an improvement not only saves materials and reduces production costs but also makes the fitness equipment more reasonable in space occupation, which is more practical for users or gyms.

[0099] 6. Combination of the stable stepping chair and the climbing pole rack: The combination of the stable stepping chair and the climbing pole rack provides more training methods. By combining the climbing pole rack with the stable stepping chair with improved stability, users can carry out more diverse training, thereby obtaining a more comprehensive physical exercise.

[0100] In summary, the improved multi-functional Pilates fitness equipment has been optimized and improved in terms of diversity, practicality, aesthetics, stability, and cost-effectiveness compared with the existing equipment, providing more comprehensive training methods and being more efficient and effective in use and production.

[0101] Figure 5 Shows an improvement in the positioning device for the lying bucket in the Pilates fitness equipment during the leather covering operation. Specifically, this is an auxiliary assembly line for improving the leather covering processing of the lying bucket, which provides assistance for various processes such as loading and unloading transmission, surface layer feeding, and locking and positioning of the semi-finished lying bucket.

[0102] The auxiliary assembly line for leather covering processing includes:

[0103] 1. The device frame 1, which includes four columns 11 standing at the corners on the ground to support the frame. Each column has a distal end 12 extending obliquely upward, and a middle beam 13 detachably connected to each distal end. The overall frame height is greater than the height of an ordinary person to facilitate the operation of the operator to bend down for construction.

[0104] 2. The base platform 2, at least partially located within the range covered by the device frame, has a certain height. Preferably, the platform is a box-shaped frame structure with a space in the middle. The frame provides a place for installing relevant action mechanisms, and the middle space leaves room for the mechanisms to move. The whole is firmly connected to the device frame.

[0105] 3. The loading and unloading transfer assembly 3, whose supporting part is fixed on the ground, and the output end of the transfer part is close to or enters one end of the base platform.

[0106] 4. The translation mechanism 4, which is designed to carry multiple functional components. It includes two guide rails 41 fixed on the base platform 2 and arranged parallel to the conveying direction of the loading and unloading transfer assembly 3, an installation platform 43 slidably matched with the two guide rails 41 through a plurality of sliders 42, and a translation power transmission system 44 for driving the installation platform 43 to move along the guide rails 41; the translation power transmission system 44 includes racks 45 arranged adjacent to each guide rail 41, gears (gears not shown) meshing with the racks 45, bevel gear sets 46 coaxially installed with the gears, a synchronous shaft 47 connecting the two bevel gear sets 46, and a driving motor 48 fixed on the installation platform 43 and drivingly connected to the synchronous shaft 47; when the translation mechanism works, after the driving motor 48 is started, it drives the two bevel gear sets 46 to act synchronously, and the two synchronously rotating gears mesh with the racks 45, thereby pushing the linear movement of the installation platform 43.

[0107] 5. The surface layer unwinding mechanism 5 is designed to replace manual surface layer laying. It comprises two centrally opposed bearing frames 51 and a unwinding frame 52 fixed to the mounting platform 43, a unwinding roller 53 rotatably connected between the two bearing frames 51, and multiple transition rollers 54 rotatably connected between the two unwinding frames 52, at least one of which is connected to a power motor 55. After the rolled elastic surface layer 223 is inserted into the unwinding rollers 52, the starting end of the elastic surface layer 223 passes through the multiple transition rollers 54. After the power motor 55 is activated, the elastic surface layer 223 is unwound or rewound via the transition rollers 54.

[0108] 6. The surface layer cutting mechanism 6 is designed to replace manual cutting of the surface layer. It includes a cylinder 61 with a guide rod or a slide fixedly mounted on two material discharging racks 52, a mounting seat 62 at the end of the telescopic free end of the cylinder 61, a profile guide rail 63 fixedly arranged between the two mounting seats 62, a sliding knife seat 64 mounted on the profile guide rail 63, and a cutting power transmission system 65 that drives the sliding knife seat 64 to move along the profile guide rail 63. The cutting power transmission system 65 can adopt a variety of existing technical forms, such as a screw motor drive. A blade is installed on the sliding knife seat 64. During operation, the cylinder 61 controls the distance between the profile guide rail 63 and the elastic surface layer 223. When the blade enters the appropriate distance for cutting the elastic surface layer 223, the cutting power transmission system 65 is started, and the movement of the sliding knife seat 64 causes the blade to cut the elastic surface layer 223.

[0109] 7. Locking and positioning mechanism 7, designed to lock the improved lying bucket to be covered, so as to facilitate the covering operation. Figure 5 , Figure 9 , Figure 11 It includes a downward pressing component 71 installed on the central beam 13, a clamping component 72 located below the central beam 13, and the clamping component 72 includes a fixed clamping block 721 located directly below the central beam 13, and a movable clamping block 722 located on both sides of the fixed clamping block 721. The two movable clamping blocks 722 are hinged to the frame of the base platform 2 on the side close to the fixed clamping block 721, and also include a first power cylinder 723 and a second power cylinder 724 that independently push the movable clamping blocks 722 to rotate. The downward pressing component 71 includes a downward pressing cylinder 711 and a downward pressing beam plate 712 installed at the telescopic free end of the cylinder. The concave arc surface of the two movable clamping blocks 722 and the one fixed clamping block 721 is preferably consistent with the curvature of the reclining bucket.

[0110] 8. The stretching and wrapping mechanism 8 is designed to flatten the cut elastic surface layer 223 as needed, replacing the manual tightening and flattening action while fixing. The original gradual tightening step is improved to a pre-tightening and flattening in one go, so that the operator only needs to focus on the fixing work when fixing the surface layer. Figure 9 , Figure 11 , Figure 12, it includes two hinge frames 81 respectively coaxially hinged to one of the movable clamping blocks 722 on both sides of the fixed clamping block 721. Telescopic stops 82 at the end away from the hinge on each hinge frame 81, two extension cylinders 83 with the body fixedly installed below the hinge frame 81 and their telescopic members fixedly connected to the telescopic stops 82, a third power cylinder 84 and a fourth power cylinder 85 respectively pushing the two hinge frames 81 to rotate, a surface layer clamping member 86 hinged to the side of each telescopic stop 82 away from the fixed clamping block 721, and a clamping cylinder 87 with the body fixed to the telescopic free end of the extension cylinder 83 and its telescopic rod hinged to the surface layer clamping member 86. Preferably, a guiding mechanism is provided between the hinge frame 81 and the telescopic stop 82. The guiding mechanism can be the cooperation of a guide rod and a hole, or other forms, such as a track.

[0111] 9. The design purpose of the lifting mechanism 9 is to cooperate with the translation mechanism 4 to extract the improved lying bucket to be covered with skin from the loading and unloading transfer assembly 3, send it to the locking and positioning mechanism 7 for locking and positioning and covering the skin. After completion, it is transported back to the loading and unloading transfer assembly 3. In this way, it can replace manual handling or the intervention of other mechanisms for handling.

[0112] The lifting mechanism 9 includes gear sets 91 respectively fixedly installed on the outer sides of each material rack 52. A bent arm 92 with one end fixedly connected to one of the gears, a sector gear 911 with an extension arm on the other gear, and a pry bar 93 with both ends fixedly connected to the extension arms of the two sector gears 911 respectively. A base is fixedly installed on the installation platform 43, and a lifting cylinder 94 with its telescopic free end rotatably sleeved on the pry bar 93 through a support. The other end of the bent arm 92 is a free end, and a propulsion assembly 95 is provided on the free ends of both bent arms 92. The propulsion assembly 95 includes a seat body 951, a propulsion cylinder 952 installed in the seat body 951, and a protruding block 953 fixedly connected to the free end of the telescopic rod body of the propulsion cylinder 952.

[0113] Figure 5 It shows that the semi-finished product 229 of the improved lying bucket is placed in the loading and unloading transfer assembly 3. In the structure of the semi-finished product 229, from Figure 4 It can be seen that both side walls of the skeleton 221 have kidney-shaped holes. These kidney-shaped holes facilitate the manual handling of the lying bucket. The shape of the protruding block 953 matches this kidney-shaped hole to minimize shaking during lifting. To adapt to different specifications of kidney-shaped holes or to cope with changes in the shape of the kidney-shaped hole, the protruding block 953 is further made into a detachable module. Specifically, a connecting seat 954 can be fixedly connected to the free end of the telescopic rod body of the propulsion cylinder 952 first, and then the protruding block 953 is detachably connected to the connecting seat 954, such as by bolt connection.

[0114] In addition, the lifting mechanism 9 adopts a lever - type prying and lifting structure, which has the characteristics of short stroke and high lifting efficiency. However, when lifting, the center of gravity of the object will tilt due to the rotation of the bent arm 92. Although it can also complete the lifting and lowering, the landing point during lowering will lose stability, especially when the placed surface of the object is an arc surface. Therefore, it is necessary to further optimize the propulsion component 95 so that the semi - finished product 229 is in a state of balanced center of gravity throughout the whole process of picking up, lifting, and finally putting down.

[0115] Combined with Figure 15 and Figure 16 , the propulsion component 95 can be set as follows:

[0116] 1. The connecting seat 954 can be rotated relative to the axis of the telescopic rod body of the propulsion cylinder 952;

[0117] 2. A propulsion frame 955 is added. This frame includes an external connection plate 001 connected to the free end of the telescopic rod body of the propulsion cylinder 952, a guide rod 002 with one end fixedly connected to the external connection plate 001 and sliding tightly as a whole in the seat body 951, and an internal connection plate 003 fixedly connected to the other end of the guide rod 002. After installation, the whole internal connection plate 003 of the propulsion frame 955 is located inside the seat body 951, and the external connection plate 001 is located outside the seat body 951;

[0118] 3. A fixed shaft 004 is fixedly arranged on the bottom surface of the connecting seat 954 on the side away from the external connection plate 001. The connecting seat 954 can be rotatably sleeved tightly on the free end of the fixed shaft 004. And, a limiting groove 005, preferably an arc - shaped limiting groove, is provided on the bottom surface of the connecting seat 954 on the side facing the internal connection plate 003. A stop rod 006 that enters the limiting groove 005 is provided in the fixed shaft 004. The range within which the connecting seat 954 can rotate is the active range between the stop rod 006 and the limiting groove 005;

[0119] 4. A reset torsion spring 007 is arranged between the bottom surface of the connecting seat 954 on the side facing the internal connection plate 003 and the internal connection plate 003. One end of the reset torsion spring 007 is clamped or inserted on the internal connection plate 003, and the other end is clamped or inserted on the connecting seat 954.

[0120] The action process and principle of the propulsion component 95 are as follows: First, the extension block 953 installed on the connecting seat 954 when it is unloaded is preset by the reset torsion spring 007 and is limited to a unified initial position by the cooperation of the torsion spring torque and the limiting groove and the rod. This is conducive to the accurate entry of the extension block 953 into the target every time it grabs. Secondly, after the installation position of the connecting seat 954 changes, its distance relative to the internal connection plate 003 is fixed, which is convenient for arranging the reset torsion spring 007.

[0121] Figure 8 and Figure 9It shows the process of lifting the semi-finished product 229. When the semi-finished product 229 is lifted, it is bent by the bending arm and rotates, the center of gravity changes, and a torsional force is generated. This torsional force opposes the torsional force of the return torsion spring 007, and the torsional force of the return torsion spring 007 is much smaller than the torsional force generated by the change of the center of gravity. Therefore, the semi-finished product 229 can always be in a state with a stable center of gravity.

[0122] The operation method of the auxiliary production line for covering leather is as follows:

[0123] 1. First, control the two movable holding blocks 722 and the two hinge frames 81 to the flattened state through the corresponding power sources, and control the surface layer clamping member 86 to the open state through the corresponding power source;

[0124] 2. The translation mechanism 4 moves, driving the surface layer feeding mechanism 5 to the telescopic stop 82 at the far end. The power motor 55 starts to feed, and the starting end of the elastic surface layer 223 is placed down into the clamping area of the surface layer clamping member 86. The power motor 55 stops, and the clamping cylinder 87 starts, and the surface layer clamping member 86 clamps the starting end of the elastic surface layer 223;

[0125] 3. The translation mechanism 4 moves to the telescopic stop 82 on the other side. At the same time, the power motor 55 starts to feed again, and the elastic surface layer 223 is laid along the traveling route. Refer to Figure 11 and Figure 10 , Figure 11 is the start, Figure 10 is the state where the laying is completed. The translation mechanism 4 moves until it is below the telescopic stop 82 on the other side;

[0126] 4. The surface layer cutting mechanism 6 starts to cut the elastic surface layer 223. Since the surface layer cutting mechanism 6 is located at a certain distance above the surface layer laying, after cutting, the material end will automatically fall into the clamping range of the surface layer clamping member 86 on this side, and the clamping cylinder 87 starts, and the surface layer clamping member 86 clamps the material end of the elastic surface layer 223;

[0127] 5. The two stretching cylinders 83 on both sides start to stretch out simultaneously, and the elastic surface layer 223 to be covered with leather is stretched and flattened;

[0128] 6. The translation mechanism 4 moves to one side of the input semi-finished product 229, and the lifting mechanism 9 starts to transport the semi-finished product 229 into the locking and positioning mechanism 7;

[0129] 7. The two hinge frames 81 rotate upward around the semi-finished product 229 under the push of the corresponding power cylinders until the semi-finished product 229 is completely covered;

[0130] 8. The pressing cylinder 711 is activated, and the pressing beam plate 712 presses the semi-finished product 229 from top to bottom. The two movable clamping blocks 722 are gradually pushed by the corresponding power cylinders to clamp the semi-finished product 229 covered by the surface layer from both sides (refer to Figure 9 ), at this time, the surface layer has wrapped the flexible material 222 in a large area and flatly. Then, loosen the two surface layer clamping members 86 and reset the two hinge frames 81;

[0131] 9. At this time, the operator uses fixing parts such as staples to connect the elastic surface layer 223 with the skeleton. After completion, cut off the excess material heads. Finally, loosen the pressing beam plate 712 and the movable clamping blocks 722, and the translation mechanism 4 drives the lifting mechanism 9 to transport the semi-finished product 229 with the surface layer wrapped to the output of the loading and unloading transfer assembly 3.

[0132] The specific embodiments described in the text are only examples to illustrate the spirit of the present invention. Those skilled in the technical field to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
