[0001] The present invention relates to the technical field of rehabilitation equipment, in particular to a stair climbing and descending rehabilitation exerciser. Background Art

[0002] In modern society, with the development of rehabilitation medicine, various rehabilitation exercise equipment has emerged to help people in need of rehabilitation to restore their physical functions. Especially in terms of the ability to go up and down stairs, traditional rehabilitation methods often rely on the guidance and assistance of physical therapists, but this method is not only labor-intensive, but also depends on the experience and skills of the therapist. Therefore, the market is in urgent need of a device that can simulate the action of going up and down stairs, is safe and effective, and can be used for autonomous rehabilitation exercises.

[0003] Most traditional stair rehabilitation equipment adopts a simple straight up and down motion mode. Although it can exercise the patient's leg muscles and joints to a certain extent, it is quite different from the movement mode of going up and down stairs in real life. In actual stair walking, the footsteps need to complete complex spatial displacement and angle changes, which puts higher demands on the patient's balance ability, coordination ability and leg muscle strength. Therefore, the development of a rehabilitation exerciser that can simulate the real stair walking trajectory is of great significance to improving the rehabilitation effect and shortening the rehabilitation cycle.

[0004] In addition, safety is also a factor that cannot be ignored in the design of rehabilitation equipment. In the early stages of rehabilitation, patients have limited physical functions and weak balance and coordination abilities, so they must have adequate safety measures when using rehabilitation equipment. Existing rehabilitation equipment often has deficiencies in safety protection, such as lack of stable support, safety belts and other protective devices, which to a certain extent limits the scope of use and rehabilitation effect of patients.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The present invention provides a stair climbing and descending rehabilitation exerciser, such as Figure 1-Figure 8 As shown, it includes a handrail 1, the bottom of the handrail 1 is supported and fixed by a bracket 3, two groups of baffle assemblies 4 are symmetrically installed at the bottom of the bracket 3, three pedals 5 are installed between the baffle assemblies 4, and the pedals 5 are driven by a driving assembly 7 to perform a circular motion in a triangular trajectory. A safety belt 2 is installed on one side of the top of the handrail 1, and the driving assembly 7 includes an outer track 71 and an inner track 72, and the outer track 71 and the inner track 72 are connected by a transmission rod 73, and the middle side of the transmission rod 73 is connected to the pedal 5. The handrail 1 is supported and fixed by the bracket 3 at the bottom, and the two groups of baffle assemblies 4 are symmetrically installed at the bottom of the bracket 3, and the stair climbing rehabilitation exerciser provided by the present invention ensures the stability and safety of the overall structure. This design not only provides a stable exercise platform for patients, but also further enhances the safety of patients during exercise through the support of the safety belt 2, effectively preventing risks such as accidental falls.

[0033] The pedal 5 is driven by the driving assembly 7 to perform a circular motion in a triangular trajectory, which cleverly simulates the actual motion trajectory of going down stairs. This motion mode can not only help patients better adapt to and restore the ability to go up and down stairs, but also effectively improve the patient's sense of balance, coordination and leg muscle strength, thereby accelerating the recovery process.

[0034] The driving assembly 7 is a combination of an outer track 71 and an inner track 72, and is connected to the pedal 5 through a transmission rod 73, thereby realizing precise driving and control of the pedal 5. This design not only improves the driving efficiency, but also ensures the stability and reliability of the pedal 5 during the movement, providing patients with a smooth and natural rehabilitation exercise experience.

[0035] Since the pedal 5 performs a circular motion in a triangular trajectory through the driving assembly 7, the parameters such as the motion trajectory, speed and amplitude can be flexibly adjusted according to the patient's rehabilitation needs and physical condition. This design enables the present invention to adapt to the rehabilitation needs of different patients and provide a more personalized rehabilitation solution.

[0036] In this embodiment, a support foot 6 is installed at the bottom of the baffle assembly 4. The installation of the support foot 6 enhances the stability of the baffle assembly 4, thereby improving the stability and safety of the entire rehabilitation exerciser. This ensures that during the use of the patient, the device can firmly support the patient's weight and the force generated by the movement, prevents the device from shaking or tilting, and provides a more secure and stable rehabilitation environment for the patient.

[0037] Specifically, the handrail 1 is a U-shaped structure, and safety belt interfaces 13 are provided at both ends of the handrail 1, and the safety belt interfaces 13 are connected to the ends of the safety belt 2. A control panel 11 is installed on the handrail 1, and grip handles 12 are installed on the top of both sides of the handrail 1. The U-shaped structure of the handrail 1 provides a wider support area for the patient, which is convenient for the patient to hold from multiple angles, and enhances the comfort and safety of use. The safety belt interface 13 is connected to the end of the safety belt 2, providing additional safety protection for the patient, especially during exercise, which can effectively prevent the patient from falling due to loss of balance. The integration of the control panel 11 makes the operation easier, and medical staff or patients can easily adjust the exercise parameters as needed. The design of the grip handle 12 further enhances the patient's experience of use, especially when performing simulated exercises of going up and down stairs, providing patients with a more stable grip point.

[0038] Further, the baffle assembly 4 includes an outer baffle 41, a first inner baffle 42 is arranged inside the outer baffle 41, and a second inner baffle 43 is arranged in the middle of the first inner baffle 42. The layered design of the baffle assembly 4 (outer baffle 41, first inner baffle 42, second inner baffle 43) not only enhances the strength of the structure, but also provides the necessary installation space and limit grooves for the drive assembly 7, ensuring the stable operation of the drive assembly. This layered design also helps to reduce the overall weight of the device while maintaining sufficient rigidity and stability.

[0039] Furthermore, the surface of the outer baffle plate 41 is provided with a first outer track limiting groove 411 and a first inner track limiting groove 412, the surface of the first inner baffle plate 42 is provided with a second outer track limiting groove 421, and the surface of the second inner baffle plate 43 is provided with a second inner track limiting groove 431. The limiting grooves (the first outer track limiting groove 411, the first inner track limiting groove 412, the second outer track limiting groove 421, the second inner track limiting groove 431) provided on the outer baffle plate 41, the first inner baffle plate 42, and the second inner baffle plate 43 ensure the stability and accuracy of the outer track 71 and the inner track 72 during the movement. The design of the limiting grooves also helps to reduce the friction and wear between the track and the baffle plate, thereby extending the service life of the equipment.

[0040] Furthermore, a triangular hole 422 is provided in the middle of the first inner baffle plate 42, and the second inner baffle plate 43 is provided inside the hole 422. The triangular hole 422 in the middle of the first inner baffle plate 42 not only reduces the weight of the baffle plate, but also provides the necessary passage space for the inner track 72, ensuring the smooth operation of the inner track. The second inner baffle plate 43 is provided inside the hole 422, further enhancing the stability and strength of the structure.

[0041] Furthermore, one side of the pedal 5 is driven to rotate by the pedal adjustment motor 76, the housing of the pedal adjustment motor 76 is fixed on the transmission rod 73, and a plurality of anti-slip strips 51 are installed on the surface of the pedal 5. This ensures that the pedal always remains horizontal during exercise, thereby improving the comfort and safety of the patient. The anti-slip strips 51 installed on the surface of the pedal effectively prevent the patient from slipping during exercise, further enhancing the safety of the device.

[0042] Furthermore, the outer track 71 is driven by an outer track driving motor 74 , and the inner track 72 is driven by an inner track driving motor 75 . Sprockets are installed on the output shafts of the outer track driving motor 74 and the inner track driving motor 75 .

[0043] Furthermore, the structures of the outer track 71 and the inner track 72 are the same. The outer track 71 includes a connecting column 711, and spherical ends 712 are installed at both ends of the connecting column 711. A snap groove 713 is installed on one side of the connecting column 711. A sleeve 714 is installed on the outer side of the snap groove 713. Adjacent snap grooves 713 are connected and matched through the sleeve 714 and the connecting column 711. The spherical end 712 of the outer track 71 slides with the first outer track limiting groove 411 and the second outer track limiting groove 421 respectively, and the spherical end 712 of the inner track 72 slides with the first inner track limiting groove 412 and the second inner track limiting groove 431 respectively. The snap groove 713 of the outer track 71 cooperates with the output shaft sprocket of the outer track driving motor 74, and the snap groove 713 of the inner track 72 cooperates with the output shaft sprocket of the inner track driving motor 75. The installation of the outer track drive motor 74 and the inner track drive motor 75 provides independent and powerful driving force for the outer track 71 and the inner track 72, ensuring stable operation and precise control of the drive assembly 7. The special structure of the track (connecting column 711, spherical end 712, buckle groove 713, sleeve 714) not only enhances the strength and durability of the track, but also ensures close fit and smooth operation between the track and the drive motor sprocket.

[0044] Furthermore, through the operation of the driving assembly 7, the transmission rod 73 is driven to move in a triangular circle with the center of the baffle assembly 4 as the center, thereby driving the pedal 5 to move in a triangular circle, and the pedal 5 is kept in a horizontal state through the flip adjustment of the pedal adjustment motor 76. This exercise mode not only simulates the actual movement trajectory of going up and down stairs, but also effectively improves the patient's balance ability, coordination and leg muscle strength. The flip adjustment of the pedal adjustment motor 76 ensures that the pedal 5 always remains in a horizontal state during the exercise, providing a stable and comfortable exercise platform for the patient.

[0045] Finally, it should be noted that the electronic components of the outer track drive motor 74, the inner track drive motor 75, the pedal adjustment motor 76, etc. involved in this embodiment are all universal standard parts or parts known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or through conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires respectively. The specific connection means should refer to the working sequence between the electrical components in the above-mentioned working principle to complete the electrical connection, which are all well-known technologies in the art.

[0046] When the stair climbing and descending rehabilitation exerciser of the present invention is used, first when the device is started, the outer track driving motor 74 and the inner track driving motor 75 start to work. The two motors provide power to the outer track 71 and the inner track 72 respectively. Sprockets are installed on the output shafts of the motors, and these sprockets cooperate with the buckle grooves 713 on the outer track 71 and the inner track 72, thereby driving the tracks to move.

[0047] The outer crawler 71 and the inner crawler 72 start to move under the drive of the motor. Since the outer crawler 71 and the inner crawler 72 are connected by the transmission rod 73, their movements are synchronized. The spherical end 712 of the outer crawler 71 slides in the first outer crawler limit groove 411 and the second outer crawler limit groove 421, while the spherical end 712 of the inner crawler 72 slides in the first inner crawler limit groove 412 and the second inner crawler limit groove 431. These limit grooves ensure the stability and accuracy of the crawler during the movement. As the crawler moves, the transmission rod 73 performs a triangular circular movement centered at the center of the baffle assembly 4.

[0048] The middle side of the transmission rod 73 is connected to the pedal 5, so when the transmission rod 73 moves, the pedal 5 also moves in a triangular trajectory. In order to ensure that the pedal 5 always remains horizontal during the movement, the pedal adjustment motor 76 starts to work. The housing of this motor is fixed on the transmission rod 73, and the pedal 5 is kept horizontal by turning over and adjusting. The surface of the pedal 5 is installed with an anti-slip strip 51, which helps prevent the patient from slipping during the exercise.

[0049] The patient stands on the pedal 5 and holds the handrail 1 or the handle 12 to maintain balance. As the pedal 5 moves in a triangular circle, the patient simulates the actual movement trajectory of going down the stairs. This exercise mode helps the patient restore the ability to go up and down stairs and improves the sense of balance, coordination and leg muscle strength.

[0050] A safety belt 2 is installed on one side of the top of the handrail 1, providing additional safety for the patient. The safety belt 2 is connected to the handrail 1 through the safety belt interface 13 to ensure that the patient will not fall due to loss of balance during exercise. The bracket 3 and the baffle assembly 4 (including the outer baffle 41, the first inner baffle 42 and the second inner baffle 43) together form a stable support structure to ensure the stability and safety of the equipment.

[0051] Medical staff or patients can easily adjust exercise parameters, such as motion trajectory, speed and amplitude, etc., through the control panel 11. This enables the present invention to adapt to the rehabilitation needs of different patients and provide a more personalized rehabilitation solution.

[0052] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
