Description

Technical Field

[0001] This utility model relates to the field of exercise equipment technology, and in particular to a limb exercise device for geriatrics. Background Technology

[0002] With the acceleration of global aging, the number of elderly people continues to grow. According to statistics from the World Health Organization, my country's population aged 60 and above has exceeded 260 million, accounting for 18.7% of the total population. Due to the decline in physical function, muscle strength, and joint flexibility, coupled with a variety of chronic diseases, the elderly population is seriously affected in terms of their physical mobility and quality of life. Their mobility difficulties not only limit their daily travel and social activities, but also increase the risk of accidents such as falls, placing a heavy burden on their families and society.

[0003] Currently, most geriatric wards and rehabilitation institutions are equipped with a limited variety of exercise equipment, mainly consisting of simple resistance bands, dumbbells, and other similar items. These devices have limited functionality and cannot meet the diverse exercise needs of the elderly. In particular, for elderly people with multiple limb diseases, a single device is insufficient to achieve rehabilitation training for multiple body parts. Therefore, we propose a limb exercise device for geriatric wards. Summary of the Invention

[0004] The purpose of this utility model is to provide a limb exercise device for geriatric wards, in order to solve the problem that most geriatric wards and rehabilitation institutions are equipped with a limited variety of exercise equipment, mainly consisting of simple resistance bands, dumbbells and other similar equipment. These devices have limited functions and cannot meet the diverse exercise needs of the elderly, especially for elderly people with multiple limb diseases, where a single device is insufficient to achieve rehabilitation training for multiple parts of the body.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a limb exercise device for geriatrics, comprising a support frame, a seat cushion fixedly installed on the top of the support frame, a backrest fixedly installed on the rear side of the seat cushion, an upper limb exercise component on the backrest, and a lower limb exercise component at the bottom of the seat cushion. The upper limb exercise component includes two sets of support seats fixedly installed on the top of the backrest, each set of support seats having a fixed pulley inside, and a limiting groove formed on the rear surface of the backrest. The two sets of fixed pulleys are connected to a handle and a pull block by a stabilizing rope.

[0006] As a preferred embodiment, two sets of railings are fixedly installed on the side of the backrest closest to the seat cushion, and the two sets of railings are located on both sides of the seat cushion. A flexible pad is fixedly installed on the side of the backrest closest to the seat cushion, and an anti-slip base is fixedly installed at the bottom of the support frame.

[0007] As a preferred embodiment, the stabilizing rope is wound around the inside of two sets of fixed pulleys, and limit sliders are fixedly installed on both sides of the pull block, with the limit sliders slidably connected to the inside of the limit groove. One end of the stabilizing rope is fixedly connected to the handle, and the other end is fixedly connected to the pull block.

[0008] As a preferred embodiment, an anti-slip pad is fixedly installed on the circumferential surface of the handle, and multiple sets of counterweights are movably installed inside the pull block.

[0009] As a preferred embodiment, the lower limb exercise component includes a mounting plate and two sets of lead screws fixedly installed inside the support frame. The front side of the seat cushion is rotatably connected to a leg support plate via a pivot. A servo motor is fixedly installed on the rear side of the mounting plate. Mounting seats are fixedly installed on the left front and rear ends and the right front end of the mounting plate. The lead screw on the left side is rotatably connected between the two sets of mounting seats, and the lead screw on the right side is fixedly connected to the output end of the servo motor.

[0010] As a preferred embodiment, threaded sliders are threadedly connected to the circumferential surfaces of both sets of lead screws, connecting blocks are fixedly installed on both sides of the bottom of the leg support plate, connecting rods are rotatably connected between the two sets of connecting blocks and the two sets of threaded sliders, pulleys are fixedly connected to the circumferential surfaces of both sets of lead screws, and belts are drivingly connected between the two sets of pulleys.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. By setting up an upper limb exercise component, when the elderly carry out upper limb training, they first sit on the cushion, add counterweights as needed, and pull the handle. During the process, the stabilizing rope moves around the groove of the fixed pulley. The fixed pulley, by virtue of its rotation around the axis, uses the groove to support and constrain the stabilizing rope, thereby pulling the block. At the same time, the limiting slider moves along the limiting groove. The fixed pulley and the limiting groove work together to maintain the stability of the pull, which greatly reduces the impact and pressure on the shoulder, elbow and other joints during the pull, and effectively avoids the risk of joint damage caused by training.

[0013] 2. By setting up a lower limb exercise component, when the elderly perform lower limb exercises, they only need to sit on the cushion, place their legs on the leg support plate, start the servo motor, and the motor drives two sets of lead screws to rotate synchronously through pulleys and belts, which in turn drives the threaded sliders on the lead screws to move. Under the action of the connecting rod, the leg support plate rotates around the cushion, causing the elderly to repeatedly lift and lower their legs. This process can fully exercise the front and back of the thighs and calf muscles, accelerate blood circulation in the legs, enhance muscle strength, effectively prevent muscle atrophy, and improve the flexibility of the leg joints.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1:

[0022] Please see the appendix Figure 1 - Appendix Figure 3 and appendix Figure 5A limb exercise device for geriatric patients includes a support frame 1, a seat cushion 2 fixedly mounted on the top of the support frame 1, a backrest 3 fixedly mounted on the rear side of the seat cushion 2, an upper limb exercise component 6 on the backrest 3, and a lower limb exercise component 5 at the bottom of the seat cushion 2. The upper limb exercise component 6 includes two sets of support seats 602 fixedly mounted on the top of the backrest 3, each set of support seats 602 having a fixed pulley 603 inside. A limit groove 601 is formed on the rear surface of the backrest 3. The two sets of fixed pulleys 603 are connected to a handle 606 and a pull block 605 by a stabilizing rope 604. Two sets of rails are fixedly mounted on the side of the backrest 3 near the seat cushion 2. The backrest 3 has a flexible pad 7 fixedly installed on the side surface of the backrest 3 near the seat cushion 2. The bottom of the support frame 1 has an anti-slip base 8 fixedly installed. The stabilizing rope 604 is wound around the inside of the two sets of fixed pulleys 603. The two sides of the pull block 605 are fixedly installed with limit sliders 607, and the limit sliders 607 are slidably connected to the inside of the limit groove 601. One end of the stabilizing rope 604 is fixedly connected to the handle 606, and the other end is fixedly connected to the pull block 605. The circumferential surface of the handle 606 is fixedly installed with an anti-slip pad. The pull block 605 has multiple sets of counterweights 608 movably installed inside.

[0023] The pull block 605 has multiple slots for installing counterweights 608. The counterweights 608 can be added or removed appropriately according to the needs of the elderly, so as to change the stretching force and effectively avoid physical injury caused by improper training intensity. With the help of the fixed pulley 603 to change the direction of the pulling force, the elderly do not need to directly overcome gravity to lift the heavy object, which reduces the difficulty of upper limb training. The simple action of pulling the handle 606 is in line with the physical function and operating habits of the elderly, making training easier.

[0024] Specifically, when an elderly person sits on the cushion 2 and needs to train their upper limbs, the number of counterweights 608 can be increased as needed. Pulling the handle 606 causes the stabilizing rope 604 to pass through the groove of the fixed pulley 603 and contact the surface of the fixed pulley 606. The fixed pulley 606 can rotate around its axis, and its groove provides support and constraint for the rope, thereby pulling the pull block 605. The limiting slider 607 moves within the limiting groove 601. The fixed pulley 603 and the limiting groove 601 ensure the stability of the pull, resulting in a smooth pulling process that reduces the impact and pressure on joints such as the shoulders and elbows, thus lowering the risk of joint damage caused by training.

[0025] Example 2:

[0026] Please see the appendix Figure 1 - Appendix Figure 4Furthermore, based on Embodiment 1, the lower limb exercise component 5 includes a mounting plate 501 fixedly installed inside the support frame 1 and two sets of lead screws 503. The front side of the seat cushion 2 is rotatably connected to a leg support plate 507 via a rotating shaft. A servo motor 502 is fixedly installed on the rear side of the surface of the mounting plate 501. Mounting seats 504 are fixedly installed on the left front and rear ends and the right front end of the mounting plate 501. The left lead screw 503 is rotatably connected between the two sets of mounting seats 504. The right lead screw 503 is fixedly connected to the output end of the servo motor 502. Threaded sliders 505 are threadedly connected to the circumferential surfaces of the two sets of lead screws 503. Connecting blocks 508 are fixedly installed on both sides of the bottom of the leg support plate 507. Connecting rods 506 are rotatably connected between the two sets of connecting blocks 508 and the two sets of threaded sliders 505. Pulleys 509 are fixedly connected to the circumferential surfaces of the two sets of lead screws 503, and a belt 510 is drivingly connected between the two sets of pulleys 509.

[0027] The servo motor 502 possesses high-precision speed and position control capabilities. Combined with the stable transmission of the pulley 509 and belt 510, it can precisely control the rotation speed and angle of the lead screw 503. This means that the range of motion parameters such as the lifting and lowering amplitude and speed of the leg support plate 507 can be precisely set, ensuring consistent movement standards in each exercise session. Compared to manual assisted exercise, this significantly improves the accuracy and effectiveness of the exercise. The operating parameters of the servo motor 502 can be adjusted according to the elderly person's physical condition and rehabilitation needs to customize a personalized exercise plan. For example, for elderly people in the early stages of rehabilitation, a slower movement speed and smaller range of motion can be set. As the rehabilitation progresses, the intensity and difficulty of the exercise can be gradually increased to meet the exercise needs at different stages.

[0028] Specifically, when elderly people need to exercise their lower limbs, they sit on the cushion 2 with their legs placed on the leg support plate 507. The servo motor 502 is activated, causing the two sets of lead screws 503 to rotate synchronously under the action of the pulley 509 and belt 510. Subsequently, the two sets of threaded sliders 505 move on the surfaces of the two sets of lead screws 503. Through the action of the connecting rod 506, the leg support plate 507 rotates around the cushion 2, allowing the elderly person's legs to lift and lower back and forth. This provides ample exercise for the muscles of the front and back of the thighs and calves, promotes blood circulation in the legs, strengthens muscles, prevents muscle atrophy, and improves the flexibility of the leg joints.

[0029] The working principle of this utility model is as follows: This utility model is a limb exercise device for geriatric patients. The elderly person sits on the seat cushion 2, with side rails 4 providing protection. The flexible pad 7 on the backrest 3 provides comfortable support for the elderly person's back. When upper limb training is needed, the number of counterweights 608 can be appropriately increased. Pulling the handle 606 causes the stabilizing rope 604 to pass through the groove of the fixed pulley 603 and contact the surface of the fixed pulley 606. The fixed pulley 606 can rotate around its axis, and its groove provides support and constraint for the rope, thereby pulling the pull block 605. The limiting slider 607 moves within the limiting groove 601. The stability of the pull is ensured by the fixed pulley 603 and the limiting groove 601. The stable pulling process reduces the impact and pressure on joints such as the shoulders and elbows. When lower limb exercise is needed, sit on the cushion 2 with your legs placed on the leg support plate 507, start the servo motor 502, and under the action of the pulley 509 and belt 510, make the two sets of lead screws 503 rotate synchronously. Then, the two sets of threaded sliders 505 move on the surfaces of the two sets of lead screws 503. Under the action of the connecting rod 506, the leg support plate 507 rotates around the cushion 2, allowing the elderly person's legs to be raised and lowered back and forth. This allows the muscles of the front and back of the thighs and calves of the elderly person to be fully exercised, promotes blood circulation in the legs, enhances muscle strength, and prevents muscle atrophy. At this point, the entire process is complete.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
