Description

Technical Field

[0001] This invention relates to the technical field of medical devices, and in particular to an exercise device for leg muscle atrophy. Background Technology

[0002] Leg muscle atrophy refers to a significant reduction in the volume of leg muscle tissue, thinning of muscle fibers, and even a decrease in the number of muscles, caused by disease, injury, malnutrition, or prolonged immobilization and lack of activity. Its core issue is an imbalance between muscle protein synthesis and catabolism, with catabolism exceeding synthesis. This manifests primarily as reduced leg circumference, muscle weakness and flaccidity, accompanied by a decline in muscle strength, endurance, and motor function, requiring the use of exercise equipment for recovery.

[0003] Leg muscle atrophy rehabilitation exercise equipment is a tool specifically designed to stimulate and restore the function and volume of atrophied muscles. Its core definition is to help patients safely and effectively conduct muscle re-education and strength training by providing controlled, progressive resistance or assisted movement.

[0004] However, current equipment offers limited training methods, especially for cycling exercises. The pedals are rigidly connected, requiring equal force on both sides. For patients with different degrees of muscle atrophy in their legs, the weaker leg does not receive sufficient exercise. Furthermore, most current exercise equipment occupies a large area, cannot be folded, and is inconvenient for storage and transportation. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an exercise device for leg muscle atrophy, which aims to solve the technical problems of the single exercise method and large size in the prior art.

[0006] To achieve the above objectives, the present invention proposes an exercise device for leg muscle atrophy, comprising a main body and a seat frame movably mounted on the main body, wherein the main body is also provided with an exercise mechanism and a massage mechanism. The exercise mechanism includes two symmetrically arranged rotating wheels that rotate within the machine body. An adjusting rod is movably arranged within each rotating wheel. At least two limiting protrusions are fixed to the inner end face of each rotating wheel. The limiting protrusions are evenly distributed circumferentially. The position of the adjusting rod replaces the position of one of the limiting protrusions. The adjusting levers abut against each other or against the limiting protrusions on opposite sides to make the two wheels rotate synchronously.

[0007] Preferably, the adjusting rod slides within the rotating wheel, and the adjusting rod has a built-in lock and extends outward. The portion of the adjusting rod located within the rotating wheel is square to prevent the adjusting rod from rotating on its own, and a collar is movably installed on the outer portion of the adjusting rod.

[0008] Preferably, the adjusting rod and the rotating wheel are connected together by a tension spring, an abutment shaft is fixedly installed on the inner side of the adjusting rod, and a push rod is fixed on the outer periphery of the abutment shaft.

[0009] Preferably, the two abutting shafts are provided with interlocking protrusions and grooves on their opposite sides, and both of them match the restricting protrusions on the opposite side.

[0010] Preferably, the machine body has a working cavity inside, the rotating wheel extends into the working cavity, and the front and rear end faces of the working cavity have extension cavities and limiting grooves, wherein two limiting grooves are provided on one side, respectively located on both sides of the extension cavity.

[0011] Preferably, a limiting block is slidably disposed in the limiting groove, and limiting springs are fixedly installed on both the upper and lower sides of the limiting block, with the other end of the limiting springs connected to the inner wall of the limiting groove.

[0012] Preferably, the massage mechanism includes two symmetrically arranged massage grooves, which are located at a right angle diagonally above the body of the machine and are recessed inward to conform to the shape of the legs. Several massage rollers are arranged inside the massage grooves, and the bottom of the massage rollers is connected to a motor, which drives the massage rollers to rotate. Several protrusions are arranged on the outer periphery of the massage rollers.

[0013] Preferably, the seat frame is slidably mounted on the body, with a seat and a movable backrest fixed on top of it, and a rear support frame rotatably connected to the bottom of the seat frame. Preferably, the backrest is rotatably mounted on the seat, and two rear support frames are provided.

[0014] Preferably, a pressure friction module is also provided inside the machine body, the pressure friction module abuts against the rotating wheel, two front support brackets are rotatably mounted on the bottom of the machine body, and two opposite support brackets are fixed on the side end faces of the machine body.

[0015] Compared with the prior art, the beneficial effects of the exercise device for leg muscle atrophy provided by the present invention are as follows: 1. Different muscle groups can be exercised by cycling, lifting the legs, and pressing down, which can fully exercise the legs of patients with muscle atrophy and accelerate the patient's recovery process.

[0016] 2. With two independent rotating wheels, each can rotate independently after the adjusting lever is pulled. At this time, the adjusting lever is locked by a latch, so pressure can be applied to one side of the rotating wheel at will. This can adapt to patients with asymmetrical muscle atrophy. Since the strength of the two legs of the patient is different, rotating wheels with different friction are used to exercise the two legs separately, so that both legs can be effectively exercised and stimulated.

[0017] 3. After exercising, you can directly place your legs into the massage tub and use the massage rollers to massage your legs, relieving congestion caused during exercise, reducing lactic acid, and further shortening the recovery process when combined with exercise.

[0018] 4. The movable seat frame allows for continuous changes in exercise posture during workouts, enhancing muscle-building effects. Adjusting the seat frame position also accommodates individuals with varying leg lengths. The rear support frame can be extended and retracted; when extended, it works in conjunction with the extended front support frame to significantly increase equipment stability and prevent tipping. Furthermore, its retractable design greatly reduces the space occupied by the exercise device when not in use, making it easy to transport and store.

[0019] The features and advantages of the present invention will be described in detail through embodiments and in conjunction with the accompanying drawings. Attached Figure Description

[0034] See Figure 1-9 This invention provides an exercise device for leg muscle atrophy, including a body 10 and a seat frame 20 movably mounted on the body 10. The body 10 also includes an exercise mechanism and a massage mechanism. The exercise mechanism includes two symmetrically arranged rotating wheels 40 that rotate within the body 10. An adjusting rod 41 is movably disposed within each rotating wheel 40. At least two limiting protrusions 401 are fixed to the inner end face of each rotating wheel 40, and the limiting protrusions 401 are evenly distributed circumferentially. The adjusting rod 41 replaces the position of one of the limiting protrusions 401. The adjusting rod 41 abuts against each other or against the limiting protrusions 401 on the opposite side to make the two rotating wheels 40 rotate simultaneously. As the machine body 10 rotates, a pressure friction module 60 is also installed inside. The pressure friction module 60 abuts against the rotating wheel 40. The friction plates inside the pressure friction module 60 can be driven electronically or hydraulically, in conjunction with an external controller, to precisely control the force required to rotate the rotating wheel 40. Two front support frames 11 are also rotatably installed at the bottom of the machine body 10. Extending the two front support frames 11 to both sides can effectively increase the overall stability of the equipment and avoid the risk of the patient falling over during exercise. Two opposite 12 are also fixed on the side end face of the machine body 10. The 12 is movable and can be cylindrical or long strip to adapt to the position of the patient's legs.

[0035] The adjusting rod 41 slides within the rotating wheel 40 and has a built-in lock (not shown in the figure). When the lock is not unlocked, the adjusting rod 41 will not slide. Only after the adjusting rod 41 is unlocked can it be pulled to slide. The adjusting rod 41 also extends outward. The part of the adjusting rod 41 inside the rotating wheel 40 is square to prevent the adjusting rod 41 from rotating on its own. The outer part of the adjusting rod 41 is movably fitted with a collar 411, which can rotate freely. The patient's foot can be placed on the collar 411 for exercise.

[0036] The adjusting rod 41 and the rotating wheel 40 are connected by a tension spring 412. An abutment shaft 413 is fixedly installed on the inner side of the adjusting rod 41, and a push rod 414 is fixed on the outer periphery of the abutment shaft 413. The opposing surfaces of the two abutment shafts 413 are provided with interlocking protrusions and grooves, which are matched with the opposite limiting protrusions 401. That is, when the two adjusting rods 41 are pulled out, the two rotating wheels 40 are independent and can rotate independently. At this time, they are locked by a lock, and pressure can be applied to one side of the rotating wheel 40 at will, so that it can adapt to patients with asymmetrical muscle atrophy. The strength of the two legs of the patient is different. Using rotating wheels 40 with different friction forces, the two legs can be exercised separately, so that both legs can be effectively exercised and stimulated.

[0037] By setting the adjustable levers 41, the adjustable levers 41 can be installed on the upper and lower sides of the rotating wheel 40 respectively, so that the abutment shaft 413 enters the corresponding limiting protrusion 401 on the opposite side. When the angle between the two adjustable levers 41 is 180°, it is similar to the pedal of a straight bicycle. Then, the patient exercises the leg atrophy by simulating riding a bicycle. At this time, the force used by the two legs is consistent, and the relative position of the adjustable levers 41 can be adjusted at will so that the angle between the two adjustable levers 41 is less than 180°. At this time, the force used by the two legs is inconsistent. The patient's legs are exercised when the two adjustable levers 41 are at different angles, so that the legs are fully exercised and the muscle atrophy is recovered as soon as possible. Since the abutment shaft 413 enters the limiting protrusion 401, the push rod 414 is exactly located at the extension cavity 102. When the rotating wheel 40 drives the push rod 414 to rotate, it will not affect other parts.

[0038] The machine body 10 has a working cavity 101 inside, and the rotating wheel 40 extends into the working cavity 101. The front and rear end faces of the working cavity 101 have extension cavities 102 and limiting grooves 103. There are two limiting grooves 103 on one side, located on both sides of the extension cavity 102. A limiting block 50 is slidably installed in the limiting groove 103. Limiting springs 501 are fixedly installed on the upper and lower sides of the limiting block 50. The other end of the limiting spring 501 is connected to the inner wall of the limiting groove 103. Since the limiting block 50 has a certain thickness and the push rod 414 just enters the limiting groove 103 along the edge, the push rod 414 cannot be pushed out from the other end under the restriction of the limiting block 50. It can only rotate in the opposite direction again and move out from the entry end.

[0039] At this time, the adjustable levers 41 are installed in contact with each other. The position of the push rod 414 is opposite to the limiting groove 103. So when the wheel 40 drives it to rotate, it will enter the limiting groove 103 and abut against the limiting block 50. When the push rod 414 rotates from the bottom away from the seat frame 20 and abuts against the bottom of the limiting block 50, the patient can put the back of both feet against the collar 411 and lift their feet up, which will cause the limiting block 50 to compress and stretch the limiting spring 501. This can exercise the muscle group when lifting the feet. When the push rod 414 rotates from the top towards the seat frame 20 and abuts against the top of the limiting block 50, the patient can put the soles of both feet on the collar 411 and press down. This can exercise the muscle group when pressing down the feet. Therefore, by adjusting the relative position of the two adjustable levers 41, different muscle groups can be exercised by riding a bicycle, lifting the feet and pressing down, so that the legs of patients with muscle atrophy can be fully exercised and the patient's recovery process can be accelerated.

[0040] The massage mechanism includes two symmetrically arranged massage grooves 30, which are located at a right angle diagonally above the body 10. They are concave inward and conform to the shape of the legs. Several massage rollers 301 are installed inside the massage grooves 30. The bottom of the massage rollers 301 is connected to a motor, which drives the massage rollers 301 to rotate. Several protrusions are provided on the outer periphery of the massage rollers 301. After exercise, the legs can be placed directly into the massage grooves 30 to massage the legs with the massage rollers 301, relieving congestion caused during exercise, reducing lactic acid, and further shortening the recovery process when combined with exercise.

[0041] The seat frame 20 is slidably mounted on the machine body 10, with a seat 201 and a movable backrest 202 fixed on top of it. The bottom of the seat frame 20 is rotatably connected to a rear support frame 203. The backrest 202 is rotatably mounted on the seat 201. There are two rear support frames 203. Through the movable seat frame 20, the exercise posture can be continuously changed during exercise to enhance muscle building. Moreover, the position of the seat frame 20 can be adjusted to accommodate people with different leg lengths. The rear support frame 203 can be extended and retracted. When extended, it works in conjunction with the extended front support frame 11 to significantly increase the stability of the equipment and prevent it from tipping over. The retractable feature also greatly reduces the footprint of the exercise device when it is not in use, making it easy to transport and store.

[0042] Working principle: When in use, pull back the seat frame 20 and adjust it to a suitable position. The patient sits on the seat 201 with the inside of the knees or the bottom of the thighs on 12 and the feet on the collar 411.

[0043] When cycling-style exercise is needed, the two adjusting levers 41 can be installed at different axis positions, that is, the abutment shaft 413 abuts against the limiting protrusion 401 on the opposite side. At this time, the patient's foot is placed on the collar 411, the pressure of the pressure friction module 60 is adjusted to a suitable value, and then the leg force is exerted to carry out the exercise.

[0044] When leg-raising exercises are required, the two adjusting rods 41 need to be installed at the bottom coaxial position, that is, the two abutting shafts 413 abut against each other and snap together. Then, the adjusting rods 41 are rotated forward from the bottom, and the patient's instep abuts against the collar 411. The patient then begins to exert upward force with the leg to perform the exercise. The limiting spring 501 can play a role in resetting.

[0045] When a downward pressing exercise is needed, based on the leg raising exercise, adjust the rotating bar 41 installed at the top, then rotate it backward from the top, and then the patient performs the exercise by pressing down with their feet.

[0046] After the exercise, the patient places their legs into the massage tank 30, then starts the motor to rotate the massage roller 301, which massages and relaxes the leg muscles.

[0047] After use, the seat frame 20 can be folded back to reduce its space occupation and stored.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
