Description
Technical Field
[0001] This invention relates to the field of training device technology, and more specifically, to a modular, combined, multifunctional physical training device. Background Technology
[0002] The physical fitness circuit device is an integrated, multi-functional training equipment that organically combines arm pushing and pulling exercises (such as rowing and shoulder press) with leg extension exercises (such as leg presses and cycling) through a linkage system. Users can perform upper and lower limb strength and endurance training synchronously or sequentially on a single device in an alternating cycle, simulating a full-body coordinated force movement pattern, improving cardiopulmonary function and muscle coordination, and achieving efficient whole-body fitness training. Furthermore, some parts of the physical fitness training device are modularly designed, allowing the structure to be adjusted according to individual needs to achieve different training methods.
[0003] Existing training devices have limited and fixed functions. For example, in leg press or arm press training, although the support position (such as foot spacing or grip width) can be manually pre-adjusted to emphasize different muscle groups, once set, the support position remains unchanged throughout the entire training movement. This static and isolated training method can only provide repetitive and concentrated stimulation to local muscles and cannot simulate the dynamic adjustment of body posture in actual sports. In complex sports scenarios such as running, climbing, and throwing, the support distance and angle of the limbs need to change in real time with the force exertion phase (such as the natural adjustment of foot spacing when jumping and the extension of the hand trajectory when pushing). The whole body's muscles achieve balanced use and power transfer in dynamic coordination. The fixed mode of existing devices lacks this dynamic adaptability of the support position during the movement process, which limits the authenticity and effectiveness of training in transforming sports performance. Summary of the Invention
[0004] This invention provides a modular, combined, multifunctional physical training device that solves the problems mentioned in the background art by gradually changing the support positions of the hands and feet, namely: fixed support positions and single function.
[0005] To achieve the above objectives, a modular, combined, multifunctional physical training device includes a flat plate with a backrest mounted on it by screws. A support plate, opposite to the backrest, is connected to the flat plate. The support plate has movable areas on both sides, with the junction of the two movable areas being a preset position for the support plate. When the support plate is subjected to a pushing force, it will move away from the backrest within the movable area; when it is subjected to a pulling force, it will move closer to the backrest within the movable area. Two symmetrically arranged foot pedals are provided on the support plate, each connected to a pull rod. An adjustment part on the support plate drives the two foot pedals to move away from or closer to each other. A left support leg and a right support leg are connected to the lower ends of the flat plate, respectively. A cavity is provided inside the left support leg, and a weight block is placed within the cavity. The weight block is connected to the support plate via a connecting part. When the support plate moves away from or closer to the backrest from the preset position, the connecting part drives the weight block to rise.
[0006] In the above technical solution, the adjustment part includes two sets of arc-shaped sliding grooves formed on the support plate. The two pedals are slidably installed in the two sets of arc-shaped sliding grooves respectively. A rotating shaft is rotatably connected to the rear wall of the support plate. A drive gear is installed on the rotating shaft. Arc-shaped racks are connected to both pedals. The two sets of arc-shaped racks are meshed and connected to both sides of the drive gear respectively. A motor that drives the rotating shaft to rotate is fixedly installed on the support plate. The arc-shaped sliding grooves are provided with strip grooves corresponding to the arc-shaped racks so that the two pedals can automatically move closer or further apart.
[0007] Based on the above, the connecting part includes a traction rope fixedly connected to the lower end of the support plate. The end of the traction rope is connected to the load block. When the support plate is in the preset position, the traction rope is basically taut and perpendicular to the plate. The plate has a through hole corresponding to the traction rope. Two symmetrically arranged guide wheels are rotatably installed in the through hole. The traction rope is located between the two guide wheels. When the support plate moves and pulls the traction rope, the traction rope presses against one of the guide wheels. This allows the entire device to achieve both pushing and pulling training.
[0008] Secondly, a support column is fixedly connected to the plate, and an inclined guide rod is slidably installed on the support column. The support plate is installed on the guide rod. When the support plate is subjected to pushing or pulling force, the support plate moves horizontally and simultaneously produces a compound motion of gradually descending or rising along the inclined direction of the guide rod, in order to make the training movements smoother and more comfortable.
[0009] Furthermore, both sides of the plate are provided with strip grooves, and sliders are slidably installed in both strip grooves. The bottom of the sliders is locked to the plate by positioning bolts. The bottom of the plate is provided with multiple positioning holes that are equally spaced to facilitate adjustment of the position of the backing plate.
[0010] Therefore, by using a motor-driven linkage mechanism to dynamically adjust the support between the hands and feet during training, the muscle groups of the upper and lower limbs can receive continuous stimulation from multiple angles in a single movement. This breaks through the limitations of traditional fixed support, simulates the coordinated force exertion pattern in actual movement, and comprehensively improves training effectiveness and functional efficiency.
[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this modular, multi-functional physical training device, a motor-driven adjustment unit dynamically adjusts the distance between the pedals and the linked levers along an arc-shaped trajectory during training. This design achieves synchronous, real-time changes in the distance between the feet and the grip width, allowing the leg and upper limb muscle groups to receive progressive stimulation from multiple angles within a single training cycle. This not only overcomes the limitations of traditional fixed support positions but also simulates the natural pattern of coordinated muscle exertion in actual exercise, significantly improving the comprehensiveness, functionality, and efficiency of training. 2. In this modular, multi-functional physical training device, through the ingenious design of the traction rope and guide wheel structure, a single weight block can simultaneously respond to both pushing and pulling action modes. Whether performing leg extension, arm press, or back pull training, the load is provided through the same resistance system, thereby achieving seamless integration of the pushing and pulling bidirectional training functions that traditionally require multiple machines on a single device. This realizes a high degree of integration of leg and arm multi-muscle group training, significantly improving the functional density and space utilization efficiency of the equipment. 3. In this modular, multi-functional physical training device, the inclined guide rod mechanism enables the support plate to simultaneously generate a vertical displacement that conforms to the natural human body when moving horizontally. This accurately simulates the biomechanical characteristics of the changes in the spatial position of the hands and feet when the limbs are extended. Together with the adjustable backrest, the inclined training angle formed by the detachable support legs, the protective cover, and the stabilizing auxiliary components, it constitutes a humanized adjustment and protection system. This makes the training movements more in line with the natural force exertion mode, improving training comfort and effectiveness. Attached Figure Description

[0014] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.
[0015] Because existing training devices have fixed and singular functions—for example, during leg presses or shoulder presses, the support position needs to be manually pre-adjusted and remains unchanged throughout the movement—this static, isolated training can only concentrate on stimulating local muscles and cannot simulate the dynamic force application patterns in actual sports. In actual sports such as running or throwing, the distance and angle of the limbs need to change in real time with each stage of the movement to coordinate the use of all muscle groups. Existing devices lack this dynamic adaptability, leading to a disconnect between training effects and actual athletic performance.
[0016] Therefore, in view of the above-mentioned problems, the present invention provides a modular, combined, multifunctional physical training device, with reference to... Figures 1-3As shown, the device includes a horizontally positioned flat plate 1. A backrest 2 for supporting the trainee's back and chest is mounted on the flat plate 1 via screws. A support plate 3, positioned opposite the backrest 2, is connected to the flat plate 1. The support plate 3 has movable areas on both sides, with the junction of the two movable areas marking a preset position for the support plate 3. When the support plate 3 is subjected to a pushing force, it will move away from the backrest 2 within the movable area; when the support plate 3 is subjected to a pulling force, it will move closer to the backrest 2 within the movable area. The support plate 3 has two symmetrically arranged foot pedals 6, each connected to a pull rod 19. The support plate 3 has an adjustment part that drives the two foot pedals 6 to move away from or closer to each other. The lower end of the plate 1 is connected to a left support leg 15 and a right support leg 17, respectively. The left support leg 15 has a cavity, and a weight block 14 to increase training intensity is set in the cavity. The weight block 14 is connected to the support plate 3 through a connecting part. When the support plate 3 moves away from or closer to the backing plate 2 from a preset position, the connecting part drives the weight block 14 to rise.
[0017] During leg training, the trainee leans against the backrest 2 with both feet on the two foot pedals 6. By intermittently extending and retracting the legs, the support plate 3 is driven to pull the weight block 14 via the connecting part, thereby achieving resistance training for the legs. When retracting, the weight block 14 pulls the support plate 3 back to its original position. The key point is that during the training process, the adjustment part drives the two foot pedals 6 to gradually move closer or further apart along an arc trajectory, dynamically changing the distance between the feet. This causes the dominant muscle group of the legs to change at different stages of the movement, thereby stimulating other muscle groups in a balanced way, avoiding over-concentration training of a single muscle group, and comprehensively improving the training effect.
[0018] When performing hand pushing exercises, the backrest 2 should be adjusted to be close to the support plate 3. The trainee holds the pull bar 19 with both hands and pushes the support plate 3 back and forth in a manner similar to leg exercises. Since the pull bar 19 is connected to the pedal 6, the change in the distance of the pedal 6 will be transmitted to the pull bar 19 in sync, so that the grip width of the hands changes intermittently during the training. This allows the pectoral muscles, anterior deltoids of the shoulders and triceps to be stimulated from a more comprehensive angle, resulting in better training effects.
[0019] When performing hand pull training, adjust the backrest 2 to be away from the support plate 3. The trainee leans against the backrest 2, holds the pull bar 19 with both hands, and pulls the support plate 3 back intermittently. Since the pull bar 19 is connected to the pedal 6, the dynamic change of the pedal 6 distance will synchronously change the hand grip distance, so that the back muscles such as the latissimus dorsi, rhomboids and biceps brachii can be trained in a balanced way from multiple angles throughout the movement.
[0020] Reference Figure 5 and Figure 6As shown, the adjustment part includes two sets of arc-shaped sliding grooves 7 formed on the support plate 3. The two arc-shaped sliding grooves 7 are symmetrically distributed on the support plate 3. The two pedals 6 are slidably installed in the two sets of arc-shaped sliding grooves 7 respectively. The rear wall of the support plate 3 is rotatably connected to a rotating shaft 8. A drive gear 9 is installed on the rotating shaft 8. Arc-shaped racks 10 are connected to the two pedals 6 and are distributed in a front-back manner on the support plate 3. The two sets of arc-shaped racks 10 are respectively meshed and connected to both sides of the drive gear 9. A motor 11 that drives the rotating shaft 8 to rotate is fixedly installed on the support plate 3. The output shaft of the motor 11 is connected to the rotating shaft 8 through a worm gear assembly 12. The arc-shaped sliding grooves 7 are provided with strip-shaped grooves 29 corresponding to the arc-shaped racks 10. The support plate 3 is provided with a cover 28 that shields the motor 11, the arc-shaped racks 10, and the drive gear 9.
[0021] When it is necessary to adjust the distance between the two pedals 6, the motor 11 is started. The motor 11 drives the rotating shaft 8 to rotate through the worm gear assembly 12. The rotating shaft 8 drives the drive gear 9 on it to rotate synchronously. The drive gear 9 meshes with the arc-shaped racks 10 arranged symmetrically on both sides, driving the two arc-shaped racks 10 to move synchronously in opposite directions along both sides of the support plate 3, thereby driving the two pedals 6 to move away from each other. Conversely, if the output shaft of the motor 11 is reversed, the two pedals 6 can be brought closer to each other through the same transmission chain.
[0022] Reference Figures 3-7 As shown, the connecting part includes a traction rope 13 fixedly connected to the lower end of the support plate 3. The traction rope 13 can actually be a steel wire rope. The end of the traction rope 13 is connected to the load block 14. When the support plate 3 is in the preset position, the traction rope 13 is basically tensioned and perpendicular to the plate 1. The plate 1 is provided with a through hole 18 corresponding to the traction rope 13. The lower end of the traction rope 13 passes downward through the through hole 18 and is connected to the load block 14. Two symmetrically arranged guide wheels 16 are rotatably installed in the through hole 18. The traction rope 13 is located between the two guide wheels 16. When the support plate 3 moves and pulls the traction rope 13, the traction rope 13 presses against one of the guide wheels 16.
[0023] When the support plate 3 is subjected to pushing or pulling force at the preset position, the weight block 14 will move upward along the guide rail through the traction rope 13. During this process, the guide wheel 16 provides support for the traction rope 13 and guides its movement direction. Through this structure, the same device can realize both pushing and pulling training modes at the same time, which significantly enhances the functionality and training diversity of the equipment.
[0024] Reference Figures 3-5As shown, a support column 4 is fixedly connected to the plate 1, and an inclined guide rod 5 is slidably installed on the support column 4. The axial cross-section of the guide rod 5 is circular. The support plate 3 is installed on the guide rod 5. When the support plate 3 is subjected to a pushing force or a pulling force, the support plate 3 moves horizontally and simultaneously generates a combined motion of gradually descending or rising along the inclined direction of the guide rod 5.
[0025] When the support plate 3 moves toward the support column 4 (for push training or leg extension), the support plate 3 drives the guide rod 5 to slide downward along the support column 4. This downward movement simulates the natural force exertion pattern of the human body: in actual exercise, when the arms or legs extend from a flexed state to a straight state, the position of the hands and feet will naturally decrease. By matching this movement trajectory, the training movements are made more in line with the biomechanical characteristics of the human body, thereby improving the naturalness and efficiency of training.
[0026] Reference Figure 4 As shown, both sides of the plate 1 are provided with strip grooves 26, and sliders 25 are slidably installed in both strip grooves 26. The bottom of the sliders 25 is locked to the plate 1 by positioning bolts 24. The bottom of the plate 1 is provided with a plurality of positioning holes 21 arranged at equal intervals.
[0027] When the position of the backing plate 2 needs to be adjusted, first loosen the positioning bolt 24, then push the backing plate 2 horizontally to the target position, and finally align the positioning bolt 24 and screw it into the positioning hole 21 corresponding to the position to lock it. This operation is simple and can quickly complete the position adjustment of the backing plate 2.
[0028] Reference Figure 4 As shown, the bottom of the plate 1 is connected to two clamping plates 30 that are away from the load block 14. A counterweight 22 is clamped between the two clamping plates 30. The counterweight 22 can improve the stability of the tail of the plate 1 and prevent the plate 1 from tilting up during training.
[0029] Reference Figures 1-3 The right support leg 17 is connected to the plate 1 by screws. When the right support leg 17 is removed, the plate 1 forms a support state that is inclined relative to the horizontal plane under the sole support of the left support leg 15.
[0030] During use, it was found that the right support leg 17, which is connected by screws, is easy for users to install and remove. After removal, the training platform is tilted, allowing trainees to lean back on the backrest 2 in a more comfortable posture, thereby optimizing the force angle and improving the training effect.
[0031] Reference Figure 2 and Figure 3As shown, a strip cover 23 is connected between the bottom of the support plate 3 and the flat plate 1. The strip cover 23 is made of rubber, and the axial cross-section of the strip cover 23 is C-shaped. The opening of the strip cover 23 faces the traction rope 13.
[0032] During the translation of the support plate 3, the flexible strip cover 23 can extend and retract with the movement, effectively shielding the operating area of the traction rope 13, thereby eliminating the risk of pinching or snagging on the trainee by the rope and significantly improving the safety of equipment use.
[0033] Reference Figure 1 and Figure 2 As shown, crossbars 20 are fixedly connected to both sides of the plate 1, and an inclined footrest 27 is connected between the left support leg 15 and the side wall of the plate 1.
[0034] When performing leg training, trainees can hold onto the fixed horizontal bar 20 with both hands to better control their body posture, maintain balance, and assist in generating force; while when performing arm training, trainees can place their feet on the footrests 27 to ensure trunk stability and concentrate the training load more on the target upper limb muscle groups.
[0035] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
