Description

Technical Field

[0001] This invention relates to the field of rehabilitation equipment technology, and in particular to a rehabilitation and fitness stepper for the elderly. Background Technology

[0002] Stepping effectively exercises the lower limb muscle groups, including the thighs, calves, and buttocks, enhancing muscle strength and improving lower limb definition. As we age, muscle mass and strength gradually decrease. By age 50, muscle strength declines by approximately 12%-15% every decade, affecting daily functional abilities. Actions such as climbing stairs and standing up from a chair become more difficult. Stepping exercises can effectively combat these declines, helping older adults maintain independence. Stepping increases heart rate and lung capacity, contributing to improved cardiopulmonary function. Regular aerobic exercise can reduce the risk of heart disease and promote heart health. The alternating footwork in stepping helps improve coordination and prevent falls. With age, the risk of falls increases, especially with weakened balance. Progressive stepping training can improve balance and lower body strength in older adults, thereby improving overall quality of life and reducing the fear of falls.

[0003] Conventional stepping devices typically only allow for simple up-and-down linear movements. When patients step on them, their foot movements are relatively simple, mainly vertical. This cannot simulate the natural foot movements, resulting in a significant gap between the exercise and real-world scenarios. It is difficult to comprehensively train the patient's lower limbs and feet, leading to a disconnect between training and rehabilitation needs. Therefore, a new type of elderly rehabilitation fitness stepping machine is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies that cannot simulate the changes in foot movements under natural conditions, resulting in a significant gap between exercise and real-world scenarios, and to propose a rehabilitation and fitness stepping machine for the elderly.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A rehabilitation and fitness stepper for the elderly includes a support plate. Symmetrically mounted round rods are mounted on the upper part of the support plate. A rotating plate is rotatably connected to the outer side of the round rods. A step box is mounted on the upper part of the rotating plate. A step plate is rotatably connected to the inner side of the step box. A driving assembly for the step plate is provided on the rotating plate. The driving assembly includes a second rotating ring rotatably connected to the side of the rotating plate, a first rotating ring rotatably connected to the side of the step box, a second transmission belt jointly sleeved on the first and second rotating rings, and a transmission unit jointly provided on the rotating plate and the support plate. When the patient steps on the step plate with both feet, causing the rotating plate and step box to rotate for training, the transmission unit drives the first rotating ring to rotate. When the first rotating ring rotates, it drives the second rotating ring through the second transmission belt. The first and second rotating rings rotate, and the rotation of the step plate increases the twisting amplitude of the feet. An adjustment component is provided on both the first and second rotating rings. The adjustment component includes multiple extension blocks that are slidably disposed on the inner sides of the first and second rotating rings, movable blocks that are slidably disposed on the inner sides of the first and second rotating rings, movable rods that are movably connected to the two movable blocks respectively, and a bidirectional threaded rod that is rotatably connected to the side of the step box. The two movable rods are threadedly connected to the bidirectional threaded rod. Rotating the bidirectional threaded rod causes the two movable rods to move in opposite directions, and respectively causes the movable blocks inside the first and second rotating rings to move in opposite directions. When the two movable blocks move in opposite directions, they cause the multiple extension blocks inside the first and second rotating rings to expand and contract.

[0006] The above technical solution further includes: The upper part of the support plate is symmetrically and movably connected with damping rods, and the end of the damping rod away from the support plate is movably connected to the rotating plate.

[0007] The upper part of the support plate is equipped with handrails, which patients can hold onto with both hands when exercising.

[0008] The transmission unit includes a first gear mounted on the outer side of a round rod, a first rotating rod rotatably connected to the side of the rotating plate, and a second gear mounted on the end of the first rotating rod away from the rotating plate. The first gear and the second gear mesh with each other, and the second gear can be driven to rotate through the first gear when the rotating plate rotates.

[0009] The transmission unit also includes a second rotating rod rotatably connected to the side of the rotating plate. A first transmission belt is sleeved between the second rotating rod and the first rotating rod. The second rotating ring is installed at the end of the second rotating rod away from the rotating plate. When the first rotating rod rotates, it can drive the second rotating rod to rotate through the first transmission belt.

[0010] The first and second rotating rings are each equipped with a support rod on their inner sides. The movable block is slidably disposed on the outer side of the support rod. The ends of the two movable rods are each equipped with a rotating block, and the rotating block and the movable block are rotatably connected.

[0011] Multiple connecting rods are rotatably connected to the outer side of the movable block. The end of the connecting rod away from the movable block is rotatably connected to the extension block. When the movable block moves, the connecting rods push or pull the multiple extension blocks to move.

[0012] The first and second rotating rings each have multiple square grooves on their inner sides. The square grooves are slidably connected to the expansion block. The size of the opening of the square groove is adapted to the size of the expansion block, and the expansion block can move along the square groove.

[0013] The end of the bidirectional threaded rod is equipped with a rotating handle.

[0014] The inner side of the step box is rotatably connected to a third rotating rod, the step plate is installed on the outer side of the third rotating rod, and the third rotating rod is fixedly connected to the first rotating ring.

[0015] The present invention has the following beneficial effects: 1. In this invention, when the patient performs stepping training by stepping on the stepping box with both feet, the stepping board can be rotated by the drive component to increase the range of foot twisting. This can simulate the movement changes of the foot in this natural state to a certain extent, making the exercise closer to the real scene. It can also increase foot twisting exercise, enrich the exercise method, and help improve the patient's lower limb and foot motor ability.

[0016] 2. In this invention, the two movable rods moving in opposite directions can drive the expansion blocks on the first and second rotating rings to expand and contract, adjust the transmission ratio of the first and second rotating rings, and ultimately adjust the twisting amplitude of the step board foot. This takes into account the needs of different patients, and can flexibly adjust the exercise intensity according to the patient's own condition, thus improving the applicability and personalization of the device.

[0019] 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.

[0020] Example 1 like Figure 1 - Figure 6As shown, the present invention proposes an elderly rehabilitation fitness stepper, comprising a support plate 1, with round rods symmetrically mounted on the upper part of the support plate 1, a rotating plate 4 rotatably connected to the outer side of the round rods 3, a step box 6 mounted on the upper part of the rotating plate 4, and step plates 7 rotatably connected to the inner side of the step box 6. A driving assembly for the step plates 7 is provided on the rotating plate 4. The driving assembly includes a second rotating ring 14 rotatably connected to the side of the rotating plate 4, a first rotating ring 13 rotatably connected to the side of the step box 6, a second transmission belt 15 jointly sleeved on the first rotating ring 13 and the second rotating ring 14, and a transmission unit jointly provided on the rotating plate 4 and the support plate 1. When the patient steps on the step plates 7 with both feet, causing the rotating plate 4 and the step box 6 to rotate for training, the transmission unit drives the first rotating ring 13 to rotate. When the first rotating ring 13 rotates, it drives the second rotating ring 7 through the second transmission belt 15. The ring 14 and the step plate 7 rotate, and the rotation of the step plate 7 increases the twisting amplitude of the foot. The first rotating ring 13 and the second rotating ring 14 are jointly provided with an adjustment component. The adjustment component includes multiple extension blocks 19 that are slidably disposed on the inner side of the first rotating ring 13 and the second rotating ring 14, movable blocks 17 that are slidably disposed on the inner side of the first rotating ring 13 and the second rotating ring 14, movable rods 21 that are movably connected to the two movable blocks 17 respectively, and a bidirectional threaded rod 23 that is rotatably connected to the side of the step box 6. The two movable rods 21 are threadedly connected to the bidirectional threaded rod 23. Rotating the bidirectional threaded rod 23 causes the two movable rods 21 to move in opposite directions, and respectively causes the movable blocks 17 inside the first rotating ring 13 and the second rotating ring 14 to move in opposite directions. When the two movable blocks 17 move in opposite directions, they cause the multiple extension blocks 19 inside the first rotating ring 13 and the second rotating ring 14 to expand and contract.

[0021] The upper part of the support plate 1 is symmetrically and movably connected with a damping rod 5, and the end of the damping rod 5 away from the support plate 1 is movably connected to the rotating plate 4.

[0022] The upper part of the support plate 1 is equipped with a handrail 2, which the patient can hold onto with both hands when exercising.

[0023] The transmission unit includes a first gear 8 mounted on the outer side of the round rod 3, a first rotating rod 10 rotatably connected to the side of the rotating plate 4, and a second gear 9 mounted on the end of the first rotating rod 10 away from the rotating plate 4. The first gear 8 and the second gear 9 mesh with each other, and the second gear 9 can be driven to rotate through the first gear 8 when the rotating plate 4 rotates.

[0024] The transmission unit also includes a second rotating rod 12 rotatably connected to the side of the rotating plate 4. A first transmission belt 11 is sleeved between the second rotating rod 12 and the first rotating rod 10. The second rotating ring 14 is installed at the end of the second rotating rod 12 away from the rotating plate 4. When the first rotating rod 10 rotates, it can drive the second rotating rod 12 to rotate through the first transmission belt 11.

[0025] In this embodiment, when the patient exercises by stepping on the step box 6, they hold the handrails 2 with both hands and step on the step plates 7 inside the step box 6 with both feet. The damping rod 5 causes the rotating plate 4 to rotate back and forth along the round rod 3. When the rotating plate 4 rotates, it drives the second gear 9 to rotate through the first gear 8. When the second gear 9 rotates, it drives the first rotating rod 10 to rotate. Since the first rotating rod 10 and the second rotating rod 12 are connected by a first transmission belt 11, the rotation of the first rotating rod 10 can drive the second rotating rod 12 to rotate through the first transmission belt 11. When the second rotating rod 12 rotates, it drives the second rotating ring 14 to rotate. Since the first rotating ring 13 and the second rotating ring 14 are connected by a second transmission belt 15, the rotation of the second rotating ring 14 can drive the first rotating ring 13 to rotate. When the first rotating ring 13 rotates, it drives the step plate 7 to rotate through the third rotating rod 25. The rotation of the step plate 7 increases the twisting amplitude of the feet.

[0026] Example 2 like Figure 1 - Figure 6 As shown, based on Embodiment 1, support rods 16 are installed on the inner sides of the first rotating ring 13 and the second rotating ring 14, the movable block 17 is slidably disposed on the outer side of the support rod 16, and rotating blocks 22 are installed at the ends of the two movable rods 21, and the rotating blocks 22 are rotatably connected to the movable blocks 17.

[0027] Multiple connecting rods 18 are rotatably connected to the outer side of the movable block 17, and the end of the connecting rod 18 away from the movable block 17 is rotatably connected to the extension block 19.

[0028] The first rotating ring 13 and the second rotating ring 14 each have a plurality of square grooves 20 on their inner sides. The square grooves 20 are slidably connected to the expansion block 19. The size of the opening of the square groove 20 is adapted to the size of the expansion block 19, and the expansion block 19 can move along the square groove 20.

[0029] A rotating handle 24 is installed at the end of the bidirectional threaded rod 23.

[0030] The inner side of the step box 6 is rotatably connected to a third rotating rod 25, and the step plate 7 is installed on the outer side of the third rotating rod 25. The third rotating rod 25 is fixedly connected to the first rotating ring 13.

[0031] In this embodiment, when the patient needs to adjust the twisting amplitude of the foot during stepping training, the bidirectional threaded rod 23 is rotated by rotating the rotating handle 24. When the bidirectional threaded rod 23 rotates, it drives two movable rods 21 to move in opposite directions. When the movable rods 21 move, they can drive two movable blocks 17 to move in opposite directions through the rotating block 22. The movable blocks 17 can move along the support rod 16. When the movable blocks 17 move, they can push or pull multiple extension blocks 19 along the square groove 20 through the connecting rod 18 to expand and contract. At this time, multiple extension blocks 19 slidably set on the first rotating ring 13 and the second rotating ring 14 expand and contract along the square groove 20 respectively. The transmission ratio of the first rotating ring 13 and the second rotating ring 14 is adjusted, thereby adjusting the twisting amplitude of the foot on the stepping plate 7.

[0032] 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.
