Description

Technical Field

[0001] This invention relates to the field of knee joint exercise and fall prevention, specifically a telescopic fall prevention knee joint exercise device. Background Technology

[0002] The knee joint is a vital joint for walking and movement, and knee rehabilitation significantly impacts daily activities and sports. After knee surgery, patients typically use a footstool for rehabilitation exercises, placing the affected foot on the stool and bending the knee to press down, thus performing knee flexion training. However, standard footstools cannot be adjusted for different flexion angles, failing to meet the needs of patients at different stages of rehabilitation; furthermore, their small bottom contact area makes them prone to slipping, posing a safety hazard during training. Most commercially available exercise equipment relies on a fixed bottom support area, taking up considerable space and easily tipping over, also presenting safety risks. Therefore, a solution that increases the support area during knee training in case of forward or lateral tilting, while also being easily folded away to minimize space usage, is a pressing issue for professionals in this field.

[0003] Contents of the telescopic anti-fall knee joint exercise device

[0004] The purpose of this invention is to provide a telescopic anti-fall knee joint exercise device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a telescopic anti-fall knee joint exercise device, comprising a base plate, the base plate being shell-shaped with an opening to the left, and a telescopic mechanism that extends to the left to increase the support area for fall prevention is inserted inside the base plate. A flip-top that can rotate counterclockwise is hinged to the upper end of the base plate, and a vertical plate is mounted on the flip-top. A support plate with its right end tilting downwards and resting on the upper end of the vertical plate is mounted on the support plate. The device also includes a pull rope mechanism disposed between the support plate and the telescopic mechanism. The pull rope mechanism can pull the telescopic mechanism to the left when the support plate and the flip-top rotate counterclockwise around the base plate. It should be noted that the base plate can be relatively heavy so that the bottom does not flip with the flip-top, and the bottom is also more stable and safer.

[0006] Preferably, the telescopic mechanism includes a telescopic plate inserted into the base plate, and the telescopic plate has a horizontally arranged strip-shaped placement groove in the middle. The telescopic plate is installed inside the base plate with a clearance fit, so that the resistance is small when it is pulled out, it is not easy to get stuck, and it is not easy to cause the base plate to tip over.

[0007] Preferably, the pull rope mechanism includes a rope hole on the upper part of the base plate, located on the upper left side of the lower placement groove. The flip plate has an upper placement groove corresponding to the position and shape of the lower placement groove, and a pull rope extending to the left is connected to the right wall of the lower placement groove. The pull rope passes upward through the rope hole and then extends to the right along the upper placement groove. After reaching its end, it bends upward and is installed on the lower right side of the pallet. The mechanism also includes a steering mechanism installed on the base plate to fix the bent pull rope to the pallet. The steering mechanism is mainly used to turn the pull rope, providing a support point for pulling it to the left. The rope hole mainly provides a support point for bending the pull rope to the right. This converts the distance the pallet flips into the distance the telescopic plate extends to the left, achieving better support. Simultaneously, there is a distance between the vertical plate and the left end of the flip plate, making it less prone to tipping over.

[0008] Preferably, the steering mechanism includes a guide ring fixed to the base plate, and the guide ring is located within the upper placement groove, with the guide ring positioned near the right end of the upper placement groove. The guide ring serves a steering function.

[0009] Preferably, it also includes a magnetic attraction mechanism disposed between the telescopic plate and the right wall of the base plate to prevent the telescopic plate from sliding freely.

[0010] Preferably, the magnetic attraction mechanism includes an outer magnet engaged with the right end of the base plate, and an inner magnet engaged with the outer magnet at the right end of the telescopic plate. The telescopic plate is fixed by the attraction between the outer and inner magnets.

[0011] Preferably, it also includes a guide mechanism disposed between the vertical plate and the flip plate to achieve height adjustment of the tray. This height adjustment accommodates patients of different sizes.

[0012] Preferably, the guiding mechanism includes a sleeve plate that fits onto the vertical plate from below, with the lower end of the sleeve plate fixed to a flap plate. A fastening knob, whose inner end abuts against the vertical plate, is threaded onto the circumferential direction of the sleeve plate. Loosening the fastening knob allows for vertical adjustment of the support plate's height.

[0013] Preferably, the upper end of the tray is provided with anti-slip guards on both the front and rear sides to prevent slipping.

[0014] Preferably, a safe distance is maintained between the rotational connection point of the flap and the base plate and the left end of the base plate to prevent the base plate from tipping over. This ensures that when the flap tipps over, a downward force is applied to the base plate, preventing it from tipping over, guaranteeing the normal extension and retraction of the telescopic plate, and ensuring safety.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The patient places their feet on the support board for exercise. If the patient falls forward, the support board will rotate around the base plate. The support board pulls the rope, which extends the telescopic board to the left through the rope hole to provide support. This increases the forward distance and prevents the patient from falling forward, ensuring safety.

[0017] 2. A safe distance is left between the connection point of the flip panel and the base plate and the left end of the base plate. In this way, the flip panel gives the base plate a downward force, which prevents the base plate from tipping over and makes it safer. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1 to 5This invention provides a telescopic anti-fall knee joint exercise device: A telescopic anti-fall knee joint exercise device includes a base plate 1, which is shell-shaped and opens to the left. A telescopic mechanism that extends to the left to increase the support area and prevent falls is inserted into the base plate 1. A flip plate 2, capable of counter-clockwise rotation, is hinged to the upper end of the base plate 1. A vertical plate 3 is mounted on the flip plate 2, and a footrest 4, with its right end tilted downwards, is mounted on the upper end of the vertical plate 3. Anti-slip edges are provided on both the front and rear sides of the upper end of the footrest 4. The device also includes a pull rope 9 mechanism located between the footrest 4 and the telescopic mechanism. The pull rope 9 mechanism can pull the telescopic mechanism to the left when the footrest 4 and the flip plate 2 rotate counter-clockwise around the base plate 1. It should be noted that the base plate 1 can be heavier so that the bottom does not flip with the flip plate 2, and the bottom is more stable and safer.

[0026] The telescopic mechanism includes a telescopic plate 5 inserted into the base plate 1, and the telescopic plate 5 has a strip-shaped lower placement groove 6 arranged on the left and right sides in the middle. The telescopic plate 5 is installed in the base plate 1 with a clearance fit, so that the resistance is small when it is pulled out, it is not easy to get stuck, and it is not easy to cause the base plate 1 to tip over.

[0027] The pull rope 9 mechanism includes a rope hole 7 on the upper end of the base plate 1, located on the upper left side of the lower placement groove 6. An upper placement groove 8, corresponding in position and shape to the lower placement groove 6, is provided on the flip plate 2. A pull rope 9 extending to the left is connected to the right wall of the lower placement groove 6. The pull rope 9 passes upward through the rope hole 7 and then extends to the right along the upper placement groove 8. After reaching its end, it bends upward and is installed on the lower right side of the support plate 4. The mechanism also includes a steering mechanism mounted on the base plate 1 to fix the bent pull rope 9 to the support plate 4. The steering mechanism is mainly used to turn the pull rope 9, providing a support point for pulling it to the left. The rope hole 7 mainly provides a support point for bending the pull rope 9 to the right. This converts the distance the support plate 4 flips into the distance the telescopic plate 5 extends to the left, achieving better support. Meanwhile, there is a distance between the vertical plate 3 and the left end of the flip plate 2, making it less likely for the flip plate 2 to tip over. The steering mechanism includes a guide ring 10 fixed to the base plate 1, and the guide ring 10 is located within the upper placement groove 8, near the right end of the upper placement groove 8. The guide ring 10 serves a steering function. A safe distance is maintained between the rotational connection point of the flip plate 2 and the base plate 1 and the left end of the base plate 1 to prevent the base plate 1 from tipping over. This way, when the flip plate 2 tipps over, it will exert a downward force on the base plate 1, preventing the base plate 1 from tipping over, ensuring the normal extension and retraction of the telescopic plate 5, and ensuring safety.

[0028] It also includes a magnetic attraction mechanism disposed between the telescopic plate 5 and the right wall of the base plate 1. This prevents the telescopic plate 5 from sliding freely. The magnetic attraction mechanism includes an outer magnet 11 that engages with the right end of the base plate 1, and an inner magnet 12 that engages with the outer magnet 11 at the right end of the telescopic plate 5. The telescopic plate 5 is fixed in place by the engagement of the outer magnet 11 and the inner magnet 12.

[0029] It also includes a guide mechanism positioned between the vertical plate 3 and the flip plate 2 to adjust the height of the tray 4. This height adjustment accommodates patients of different sizes. The guide mechanism includes a sleeve 13 that fits onto the vertical plate 3 from below, with the lower end of the sleeve 13 fixed to the flip plate 2. A fastening knob, whose inner end abuts against the vertical plate 3, is threaded onto the circumferential direction of the sleeve 13. Loosening the fastening knob allows the height of the tray 4 to be adjusted up and down.

[0030] Working principle: When the patient's foot is placed on the support plate 4 for exercise, if it tilts forward, the flip plate 2 will rotate around the base plate 1. The flip plate 2 pulls the pull rope 9, which, through the rope hole 7, pulls the telescopic plate 5 to the left to provide support. This increases the forward distance, preventing further tilting and ensuring safety. A safe distance is maintained between the connection point of the flip plate 2 and the left end of the base plate 1. This allows the flip plate 2 to exert a downward force on the base plate 1, preventing it from tilting and further enhancing safety.

[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
