Description

Technical Field

[0001] This invention relates to the technical field of health training equipment, and more particularly to a bone protection and motor function training device for obese children. Background Technology

[0002] In recent years, with the continuous rise in childhood obesity rates, related health problems have received increasing attention. Obese children are more prone to chronic diseases such as fatty liver, hypertension, and coronary heart disease, and also exhibit abnormalities in fat and glucose metabolism, which is one of the early symptoms of childhood diabetes. Furthermore, the impact of obesity on the mental health of adolescents should not be underestimated, affecting not only daily life and learning but also potentially having a negative impact on their future social lives.

[0003] Currently, although training equipment for the health management of obese children exists, such as the patent CN114558278B which discloses a comprehensive health training device and method for obese children, including a base plate, a standing seat fixedly connected to the upper outer wall of the base plate, a seat platform on one side of the standing seat, a rear seat with a correction component on the side of the seat platform near the standing seat, and an inner sliding seat fixedly connected to the lower outer wall of the standing seat, the above patent involves having the child sit on the seat platform and then pull the handle with their arms to lift their legs, thus simultaneously exercising the child's arms and legs. However, this training method only supports localized activities of the arms or lower limbs and cannot meet the training needs of whole-body movements such as standing, walking, turning, and jumping. It suffers from problems such as relatively simple training content and incomplete muscle activation. Long-term use of this type of equipment may lead to a phenomenon of "local fatigue and overall ineffectiveness," which will reduce training efficiency and make it difficult to improve overall physical fitness and athletic ability, thus hindering the physical coordination development and weight control goals of obese children. Summary of the Invention

[0004] In view of this, the present invention provides a skeletal protection and motor function training device for obese children, which can overcome the shortcomings of existing training devices that only support local activities of the arms or lower limbs and cannot meet the training needs of whole-body movements such as standing, walking, turning, and jumping.

[0006] In a preferred embodiment of the present invention, the lifting assembly includes: a drive motor mounted on the top of the fixed frame; a threaded rod connected to the output shaft of the drive motor, and the threaded rod passing through the middle of the first slide plate; and a threaded sleeve connected to the top of the second slide plate, and the threaded sleeve being threadedly connected to the threaded rod.

[0007] In a preferred embodiment of the present invention, the invention further includes: a guide tube connected to a support plate; a second pull rope slidably connected to the inside of the guide tube; a handle connected to one end of the second pull rope; a square frame slidably connected to the side of the support plate, and the other end of the second pull rope is fixedly connected to the square frame, with the first pull rope slidably passing through the inside of the square frame; and a second roller rotatably connected to the square frame, with the second roller contacting and engaging with the first pull rope.

[0008] In a preferred embodiment of the present invention, the device further includes: a fixed rod connected to the bottom of the arc-shaped frame; a first rotating rod rotatably connected to the lower end of the fixed rod; a second rotating rod rotatably connected to the lower end of the first rotating rod; straps symmetrically installed on the sides of the first rotating rod and the second rotating rod; and a swinging mechanism disposed on the fixed rod for driving the first rotating rod and the second rotating rod to swing.

[0009] In a preferred embodiment of the present invention, the swing mechanism includes: a first electric push rod, rotatably mounted on a fixed rod; a connecting rod, connected to the telescopic rod of the first electric push rod; a connecting frame, connected to the side of the first rotating rod, and the connecting rod and the connecting frame are movably engaged; a second electric push rod, rotatably mounted on the first rotating rod; and a hinge plate, rotatably connected to the telescopic rod of the second electric push rod, and the hinge plate and the second rotating rod are rotatably connected.

[0010] In a preferred embodiment of the present invention, the device further includes: a connecting seat, which is connected to the treadmill and the arc-shaped frame respectively; a rotating ball, which is rotatably connected to the inside of the connecting seat; a guide sleeve, which is connected to the lower rotating ball; a sliding rod, which is connected to the upper rotating ball and is slidably connected to the guide sleeve; a buffer spring, which is wrapped around the outside of the sliding rod and whose two ends are connected to the guide sleeve and the sliding rod respectively; a level sensor, which is mounted on one of the arc-shaped frames; and a locking mechanism, which is disposed on the guide sleeve and is used to lock the sliding rod.

[0012] In a preferred embodiment of the present invention, it further includes: rubber sheaths symmetrically fitted onto the handrails of the treadmill.

[0013] Compared with the prior art, the present invention has the following advantages: 1. The present invention enables obese children to perform whole-body exercise training such as standing, walking and running in a weight loss state through the combination of treadmill, arc frame and safety belt. The elastic support system composed of first slide, second slide and connecting spring can adjust the support force according to the child's weight, effectively reduce the load on bones and avoid joint damage caused by excessive weight.

[0014] 2. The present invention adopts a linkage design of the second pull rope, the square frame and the second roller. Children can pull down the handle to drive the first pull rope to bend, forming a resistance training. This structure, combined with the elastic resistance of the connecting spring, makes upper limb training more flexible and controllable, while avoiding the limitations of traditional equipment that only relies on local muscle movement.

[0015] 3. This invention uses a horizontal sensor to monitor the tilt angle of the arc-shaped frame in real time. When a risk of imbalance is detected, the wireless controller immediately activates the electromagnet to attract the sliding rod. Combined with the buffering effect of the buffer spring, the sliding rod can be quickly locked to prevent children from falling. This mechanism, combined with the omnidirectional adjustment capability of the rotating ball and the guide sleeve, ensures the safety and stability of the training process.

Detailed Implementation

[0026] Example: A bone protection and motor function training device for obese children, such as... Figures 1-3As shown, the treadmill includes a treadmill 1, first rollers 2, fixed frames 3, first slide plates 4, second slide plates 5, connecting springs 6, support plates 7, guide wheels 8, first pull ropes 9, arc-shaped frames 10, buckles 11, arc-shaped rods 12, safety belts 13, carabiners 14, and lifting components. Multiple first rollers 2 are rotatably connected to the lower front and rear sides of the treadmill 1. Two fixed frames 3 are symmetrically connected to the lower front and rear of the treadmill 1. First slide plates 4 are slidably connected to the upper inner sides of both fixed frames 3. Each of the four treadmills 1 has a second slide plate 5 slidably connected to it. A connecting spring 6 is symmetrically connected between the bottom of the first slide plate 4 and the top of the second slide plate 5. Two support plates 7 are connected to the front and rear sides of the treadmill 1. A guide wheel 8 is rotatably connected to the upper part of each of the four support plates 7. A first pull rope 9 is slidably connected inside each of the four support plates 7, and the first pull rope 9 passes over the first roller 2 and the guide wheel 8. One end of the first pull rope 9 is fixedly connected to the first slide plate 4. Two arc-shaped frames 10 are provided, and the right sides of the two arc-shaped frames 10 are hinged together (to...). Figure 1 (Described from the perspective shown), and the other ends of the two first pull ropes 9 on the rear side are connected to the arc-shaped frame 10 on the rear side, while the other ends of the two first pull ropes 9 on the front side are connected to the arc-shaped frame 10 on the front side. A buckle 11 is installed on the left side of the two arc-shaped frames 10. Two arc-shaped rods 12 are connected to the side of the two arc-shaped frames 10 that are close to each other. A safety belt 13 is provided below the arc-shaped frame 10. Four carabiners 14 are symmetrically installed on the safety belt 13, and the carabiners 14 can be fastened to the arc-shaped rods 12. A lifting component for controlling the second slide 5 to rise and fall is provided on the fixed frame 3.

[0027] like Figure 2 As shown, the lifting assembly includes a drive motor 15, a threaded rod 16, and a threaded sleeve 17. The drive motor 15 is installed at the top center of both fixed frames 3. The output shaft of the drive motor 15 is connected to the threaded rod 16, and the threaded rod 16 passes through the middle of the first slide plate 4. The top of the second slide plate 5 is connected to the threaded sleeve 17, and the threaded sleeve 17 is threadedly connected to the threaded rod 16.

[0028] When an obese child needs to use this device for training, first, the safety belt 13 is put on the child. Then, the buckle 11 is opened, and the two curved frames 10 are rotated to the side furthest from each other. The child then stands on the treadmill 1, positioned between the two curved frames 10. Next, the two curved frames 10 are rotated to the side closest to each other and the buckle 11 is closed. Then, the carabiner 14 is fastened to the curved rod 12 to secure the safety belt 13 to the curved frame 10. Then, according to the child's weight, the drive motor 15 drives the threaded rod 16 to rotate a specified number of times. The threaded rod 16 can drive the threaded sleeve 17 and the second slide plate 5 to move upward, thereby narrowing the gap between the first slide plate 4 and the second slide plate 5. The distance is such that the connecting spring 6 is compressed, thereby adjusting the degree of compression of the connecting spring 6. Under the elastic force of the connecting spring 6, the first slide plate 4 will be subjected to an upward pulling force. The first slide plate 4 can provide an upward pulling force to the arc frame 10 through the first pull rope 9. The arc frame 10 can apply the above pulling force to the child's body through the safety belt 13, thereby overcoming the child's own weight through the above pulling force, so as to reduce the weight borne by the child's bones. Then the child can carry out full-body movement training on the treadmill 1, and can also carry out running training with the help of the treadmill 1. During the training process, since the child is in a weight loss state, the child's bones can be protected to prevent their bones from being damaged due to the child's own excessive weight.

[0029] like Figure 4 and Figure 5 As shown, it also includes a guide tube 18, a second pull rope 19, a handle 20, a square frame 21, and a second roller 22. The two support plates 7 on the right side are each connected to a guide tube 18, and the two guide tubes 18 are each slidably connected to a second pull rope 19. The upper ends of the two second pull ropes 19 are each connected to a handle 20. The lower parts of the two support plates 7 on the right side are each slidably connected to a square frame 21. The lower ends of the second pull ropes 19 are fixedly connected to the square frames 21, and the first pull rope 9 slides through the inner side of the square frame 21. The lower parts of the two square frames 21 are each rotatably connected to a second roller 22, and the top of the second roller 22 contacts and engages with the first pull rope 9.

[0030] When a child needs to perform upper limb training alone, they can stand directly on the treadmill 1, adjust the compression of the connecting spring 6, then hold the handle 20 and pull it down. The handle 20, through the second pull rope 19, can pull the square 21 and the second roller 22 upwards. The second roller 22 will squeeze the first pull rope 9 and cause it to bend and deform. When the first pull rope 9 bends and deforms, it needs to overcome the elasticity of the connecting spring 6, thus forming a resistance training. Then, release the handle 20, and the first pull rope 9 will return to its original shape due to the elasticity of the connecting spring 6. The first pull rope 9 will also squeeze the square 21 and the second roller 22 downwards. The square 21, through the second pull rope 19, can pull the handle 20 upwards to return to its original position. Repeat this operation to complete the upper limb training.

[0031] like Figure 6 As shown, it also includes a fixed rod 23, a first rotating rod 24, a second rotating rod 25, straps 26, and a swing mechanism. The bottom of each of the two arc-shaped frames 10 is connected to a fixed rod 23. The lower end of the fixed rod 23 is rotatably connected to the first rotating rod 24, and the lower end of the first rotating rod 24 is rotatably connected to the second rotating rod 25. Two straps 26 are installed on the sides of the first rotating rod 24 and the second rotating rod 25 that are close to each other on both the front and rear sides. The fixed rod 23 is provided with a swing mechanism for driving the first rotating rod 24 and the second rotating rod 25 to swing. The swing mechanism includes a first... The device includes an electric push rod 27, a connecting rod 28, a connecting frame 29, a second electric push rod 30, and a hinge plate 31. The upper part of the two fixed rods 23 is rotatably mounted with the first electric push rod 27. The telescopic rod of the first electric push rod 27 is connected to the connecting rod 28. The sides of the two first rotating rods 24 are connected to the connecting frame 29, and the connecting rod 28 is located inside the connecting frame 29. The second electric push rod 30 is rotatably mounted on the two first rotating rods 24. The telescopic rod of the second electric push rod 30 is rotatably connected to the hinge plate 31, and the hinge plate 31 is rotatably connected to the second rotating rod 25.

[0032] When children are training to walk or run, the straps 26 on the first rotating rod 24 and the second rotating rod 25 can be tied to the child's thighs and calves respectively. Then, the first electric push rod 27 and the second electric push rod 30 can be controlled to reciprocate. The first electric push rod 27 can drive the first rotating rod 24 to swing with its upper end as the center of rotation through the cooperation of the connecting rod 28 and the connecting frame 29. The second electric push rod 30 can drive the second rotating rod 25 to swing with its upper end as the center of rotation through the hinge plate 31. This can assist children in training to walk or run and can correct the child's walking posture.

[0033] like Figures 7-9As shown, it also includes a connecting seat 32, a rotating ball 33, a guide sleeve 34, a sliding rod 35, a buffer spring 36, a level sensor 37, and a locking mechanism. Two connecting seats 32 are connected to the lower right side of the treadmill 1, and two connecting seats 32 are connected to the right sides of the two arc-shaped frames 10. There are four connecting seats 32, arranged in pairs. A rotating ball 33 is rotatably connected inside each of the four connecting seats 32. Guide sleeves 34 are connected to the two lower rotating balls 33. Sliding rods 35 are slidably connected inside each of the two guide sleeves 34, with the upper end of the sliding rod 35 connected to the upper rotating ball 33. A buffer spring 36 is wound around the outer side of each sliding rod 35, and the two ends of the buffer spring 36 are connected to the guide sleeve 34 and the sliding rod 35, respectively. The front... A horizontal sensor 37 is installed on the right side of the arc-shaped frame 10. The horizontal sensor 37 is equipped with a corresponding wireless controller (not shown in the figure). The guide sleeve 34 is provided with a locking mechanism for locking the sliding rod 35. The locking mechanism includes a fixed cylinder 38, an electromagnet 39 and a connecting wire 3901. The outer sides of the two guide sleeves 34 are connected to the fixed cylinder 38. Three electromagnets 39 are installed on each of the two fixed cylinders 38. The sliding rod 35 is made of iron. After the electromagnet 39 is energized and magnetized, it can attract the sliding rod 35 by magnetic force to lock the sliding rod 35. The three electromagnets 39 are connected in series through the connecting wire 3901 so that the three electromagnets 39 can work synchronously. The electromagnets 39 are electrically connected to the wireless controller.

[0034] When a child is engaged in full-body movement training, the curved frame 10 will sway with the child's body movement, causing the sliding rod 35 to slide within the guide sleeve 34. The buffer spring 36 will adapt by extending and contracting. The guide sleeve 34 and the sliding rod 35 will also adapt by oscillating in conjunction with the connecting seat 32 and the rotating ball 33. The curved frame 10 will also cause the horizontal sensor 37 to sway. The horizontal sensor 37 can detect the tilt angle of the curved frame 10. When the horizontal sensor 37 detects that the tilt angle of the curved frame 10 exceeds a safety threshold, the table... If a child loses balance and falls, the electromagnet 39 is activated via the wireless controller. The energized electromagnet 39 generates a strong magnetic field, attracting the iron sliding rod 35 and fixing it inside the guide sleeve 34. This limits the further tilting of the arc frame 10, providing fall protection and improving safety. Once the child regains their footing, the horizontal sensor 37 detects that the tilt angle of the arc frame 10 is less than a preset value. The horizontal sensor 37 sends a signal, and the wireless controller, upon receiving the signal, de-energizes the electromagnet 39 to release the lock on the sliding rod 35.

[0035] like Figure 1As shown, it also includes rubber sleeves 40. Both the front and rear handrails on the upper part of the treadmill 1 are covered with rubber sleeves 40. When children exercise on the treadmill 1, they can hold onto the handrails of the treadmill 1. The rubber sleeves 40 are used to increase the friction between the child's hands and the handrails of the treadmill 1 to prevent slipping and to prevent the child from bumping into the handrails of the treadmill 1, thus improving safety.
