Description

Technical Field

[0001] This utility model relates to the field of training equipment technology, and in particular to upper and lower limb training equipment. Background Technology

[0002] In the rehabilitation process, effective rehabilitation training is crucial for patients who are bedridden for extended periods, especially those with impaired limb motor function. Several rehabilitation devices have emerged on the market that train the upper and lower limbs of bedridden patients separately. However, these devices typically require moving the patient from a regular hospital bed to a specialized rehabilitation training bed, with doctors assisting with the training. This process places a significant burden on family members, caregivers, and medical staff. Therefore, devices that allow for limb rehabilitation training for bedridden patients without changing beds have appeared on the market.

[0003] For example, the Chinese utility model patent CN220967631U, entitled "A Mobile Upper and Lower Limb Muscle Strength Training and Rehabilitation Device," includes a support frame, which is an arch-shaped support frame. The support columns on both sides of the support frame are composed of a lower fixed column and an upper telescopic column. An upper limb auxiliary rehabilitation training device is set on the top crossbeam of the support frame. The upper limb auxiliary rehabilitation training device includes upper limb traction crossbars hinged to both sides of the top crossbeam. A tension spring is set at the movable end of the upper limb traction crossbar. A hand pull ring is set at the lower part of the upper limb traction crossbar via a traction belt. A lower limb auxiliary rehabilitation training device is set in the middle of the telescopic column via a transverse support shaft. The lower limb auxiliary rehabilitation training device includes a foldable support plate composed of a connecting plate and a front end plate hinged by a pivot. The root of the connecting plate is connected to the transverse support shaft. A rotating roller is set on the outer side of the end of the front end plate. Two cables are connected to the middle of the foldable support plate, which are respectively close to the ends of the tension springs of the two upper limb traction crossbars. The upper part of the cables is respectively hooked to two sets of fixed pulleys set on the top crossbeam of the support frame for guidance.

[0004] In the above program, both the patient's upper and lower limbs can be trained. However, during the rehabilitation training, the two lower limbs need to push the front plate forward to extend or pull the front plate backward to fold. Under the action of the cable, the two upper limbs move upward as the two lower limbs push forward and downward as the two lower limbs pull backward. The coordination is poor and the experience is poor. Utility Model Content

[0005] This invention addresses the problems of poor coordination and poor user experience when upper and lower limbs are trained together in rehabilitation training devices. The technical problem to be solved by this invention is to provide an upper and lower limb training device to solve the above problems.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: it includes a base and a support frame that spans across the base and is fixed to the base on the lower side. The base is rotatably provided with a mounting seat, which can be flipped up or down relative to the base to adjust its angle with the base. A support member is provided between the base and the mounting seat to support and limit the mounting seat after it is flipped. A stepper is fixedly provided on the mounting seat. Two pull ropes are slidably provided on the support frame. One end of the two pull ropes is connected to the left and right pedals of the stepper, respectively. The other end of the two pull ropes is used to connect the left and right upper limbs of the trainee. When training, the mounting seat is adjusted to flip up relative to the base so that the stepper rotates with the mounting seat to an angle suitable for the trainee to lie down or sit for training. The ends of the two pull ropes away from the stepper are connected to the upper limbs of the trainee. When the trainee uses the stepper, the stepper can drive the trainee's arms to move up and down through the two pull ropes.

[0007] A further preferred embodiment of this utility model is: two fixed pulleys are provided on both sides of the support frame, and two pull ropes are respectively looped on the fixed pulleys on the corresponding sides.

[0008] A further preferred embodiment of this utility model is: the base is provided with a mounting position for accommodating a mounting seat, the mounting seat is rotatably connected to the mounting position and flips towards the support frame when flipped.

[0009] A further preferred embodiment of this utility model is: the two side walls of the mounting position extend vertically above the upper surface of the base, and the mounting base can be flipped downwards and folded into the mounting position.

[0010] A further preferred embodiment of this utility model is as follows: the support member includes two support rods and one limiting rod. One end of each of the two support rods is rotatably connected to the two side walls of the mounting base, and the other end is fixed to both sides of the limiting rod. Both sides of the mounting base are provided with a row of slots that cooperate with the limiting rod and are arranged along the direction of the support frame. When the mounting base is flipped, both ends of the limiting rod are respectively locked in the corresponding slots to support and limit the mounting base.

[0011] A further preferred embodiment of this utility model is: two rows of card slots are symmetrically arranged, with at least one card slot in each row.

[0012] A further preferred embodiment of this utility model is: the support frame includes two parallel columns and a crossbeam fixed to the upper end of the two columns, and the lower side of the columns is fixed to the base.

[0013] A further preferred embodiment of this utility model is as follows: the column includes an upper upright, a sleeve, and a lower upright. The lower side of the upper upright and the upper side of the lower upright are both located inside the sleeve and can slide relative to the sleeve to adjust the height of the column. The lower side of the upper upright and the upper side of the lower upright are both provided with fixing members. When the upper upright and / or the lower upright slide to the target position, the fixing members fix the upper upright and / or the lower upright inside the sleeve.

[0014] A further preferred embodiment of this utility model is that the upper pipe, sleeve, and lower pipe are non-circular tubes.

[0015] A further preferred embodiment of this utility model is as follows: A fixing seat is provided on both sides of the base. The fixing seat has a fixing groove for inserting the lower end of the column. The fixing groove has a shaft hole that extends horizontally through both sides of the groove wall and several mounting holes distributed circumferentially around the shaft hole. The lower side of the column has a connecting hole and a fixing hole. The distance between the connecting hole and the fixing hole is equal to the distance between the shaft hole and any mounting hole. The column is rotatably connected to the fixing seat via a rotating shaft passing through the connecting hole and the shaft hole. When the support frame rotates around the shaft to any mounting hole position, the fixing hole corresponds to the mounting hole at that location. Bolts are passed through the mounting holes and fixing holes, and then nuts are used to fix the column to the base.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. A mounting base that can flip up or down relative to the base is installed on the base. A stepper is fixed on the mounting base, and two pull ropes slide on the support frame. One end of the two pull ropes is connected to the left and right pedals of the stepper, respectively. The other end of the two pull ropes is used to connect the left and right upper limbs of the trainee. When the trainee uses the stepper to train the lower limbs, the movement of the stepper can drive the arm movement. When the right pedal of the stepper is stepped forward, the right upper limb moves upward. When the left pedal of the stepper is stepped forward, the left upper limb moves upward. At the same time, the right pedal moves backward and the right upper limb moves downward. The left and right upper limbs always maintain an upward and downward movement state, and the left and right lower limbs always maintain a forward and backward state. By rotating the stepper and pulling the pull ropes, the upper limbs of the trainee, especially those with hemiplegia or muscle weakness, are coordinated with the lower limbs, achieving the purpose of coordinated rehabilitation of the upper and lower limbs and improving the effect of rehabilitation training.

[0018] 2. The flip-up mounting base allows the stepper to be adjusted to meet the training needs of different trainees, especially those with hemiplegia or myasthenia gravis, thus improving the applicability and flexibility of the equipment. Attached Figure Description

[0028] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0029] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0030] This embodiment mainly describes the upper and lower limb training device, as detailed below:

[0031] like Figures 1 to 5 As shown, the upper and lower limb training device includes a base 1 and a support frame 2. The base 1 is used for placement on a bed, serving as support and mounting. The support frame 2 spans across the base 1, and its lower side is fixed to the base 1. The base 1 is provided with a mounting seat 4 that can be flipped up or down relative to the base 1. A support member 5 is provided between the base 1 and the mounting seat 4 to provide support and limit the mounting seat 4 after it is flipped. A stepper 6 is fixed to the mounting seat 4 by bolts and nuts. Two pull ropes 7 are slidably mounted on the support frame 2. One end of the two pull ropes 7 is connected to the left pedal 61 and the right pedal 62 of the stepper 6, respectively, and the other end of the two pull ropes 7 is used to connect the trainee's left and right upper limbs, respectively. When performing rehabilitation training, the trainee can lie on a bed or sit on a stool. This new training device can be used while sitting or lying down, allowing the user to choose according to their physical condition and personal habits. When the trainee is lying down, the device is placed on the bed, and the mounting base 4 is adjusted to tilt upwards relative to the base 1, causing the stepper 6 to rotate to an angle suitable for the trainee's lying position. When the trainee is sitting, the device is placed on the ground, and the mounting base 4 is adjusted to rotate the stepper 6 to a training angle suitable for the trainee's sitting position. Two pull ropes 7 are connected to the upper limbs of the trainee at the ends furthest from the stepper 6. When the trainee uses the stepper 6, the two pull ropes 7 can move the trainee's arms up and down. When the right pedal 62 of the stepper 6 is stepped forward, the right upper limb moves upward; when the left pedal 61 of the stepper 6 is stepped forward, the left upper limb moves upward. At the same time, the right pedal 62 moves backward and the right upper limb moves downward. The left and right upper limbs always maintain an up-and-down movement, and the left and right lower limbs always maintain a forward-and-backward movement. In this design, the rotation of the stepper pulls the ropes, enabling the trainee, especially those with hemiplegia or myasthenia gravis, to move their upper limbs, achieving the goal of coordinated upper and lower limb rehabilitation and improving the effectiveness of rehabilitation training. Simultaneously, the flip-up mounting base allows the stepper's position to be adjusted to meet the training needs of different trainees, especially those with hemiplegia or myasthenia gravis, improving the applicability and flexibility of the equipment. This training device is primarily designed for people with hemiplegia or myasthenia gravis, but it is not limited to use by people with hemiplegia or myasthenia gravis; it is also suitable for use by completely healthy individuals for limb training.

[0032] Specifically, the support frame 2 has two fixed pulleys 8 on both sides, and two pull ropes 7 are respectively fitted onto the fixed pulleys 8 on the corresponding sides. The fixed pulleys 8 can change the direction of force on the pull ropes 7, making the pull ropes 7 smoother when moving the trainee's arms, reducing friction between the pull ropes 7 and the support frame 2, extending the service life of the pull ropes 7, and also improving comfort and safety during training, ensuring that the trainee can perform upper and lower limb coordinated training more smoothly during training.

[0033] like Figure 4 As shown, the base 1 has a mounting position 11 for accommodating the mounting seat 4. The mounting seat 4 is rotatably connected to the mounting position 11 via a shaft and flips towards the support frame 2 during rotation. By setting the mounting position 11, a stable mounting base is provided for the mounting seat 4, allowing it to be firmly connected to the base 1 and smoothly flip towards the support frame 2 along a predetermined trajectory during rotation. This ensures the smoothness and accuracy of the rotation action of the mounting seat 4, further improving the stability and reliability of the equipment and providing a good foundation for rehabilitation training.

[0034] Specifically, the two side walls of the mounting position 11 extend vertically above the upper surface of the base 1, and the mounting base 4 can be flipped down and folded into the mounting position 11. This design allows the mounting base 4 to be completely stored in the mounting position 11 when not in use, reducing the overall size of the equipment, facilitating storage and transportation, and also preventing the mounting base 4 from occupying too much space when not in use, thus improving the space utilization of the equipment and making it more suitable for use in places with limited space, such as homes.

[0035] Specifically, the support component 5 includes two support rods 51 and a limiting rod 52. One end of each support rod 51 is rotatably connected to the two side walls of the mounting base 4, and the other end is fixedly connected to both sides of the limiting rod 52. Both sides of the mounting position 11 are provided with a row of slots 12 that cooperate with the limiting rod 52 and are arranged along the direction of the support frame 2. When the mounting base 4 is flipped, both ends of the limiting rod 52 are respectively engaged in the corresponding slots 12 to support and limit the mounting base 4. This structure of the support component 5 enables stable support and limiting of the mounting base 4 at different flipping angles. When the mounting base 4 is flipped to a suitable angle, the limiting rod 52 can be engaged in the corresponding slot 12, thereby firmly fixing the mounting base 4 in that position, ensuring that the stepper 6 maintains a stable angle during training, allowing the trainee to train more comfortably. At the same time, this adjustable support and limiting method allows for flexible adjustment of the stepper 6 angle according to the trainee's physical condition, improving the personalized adaptability of the equipment and better meeting the training needs of different trainees.

[0036] Specifically, the two rows of slots 12 are symmetrically arranged, with at least one slot in each row. The symmetrical arrangement of the slots 12 ensures that the supporting force on both sides of the mounting base 4 is evenly distributed during the flipping process, further improving the stability of the mounting base 4. At the same time, the presence of multiple slots in each row provides multiple selectable support positions for the mounting base 4, making the angle adjustment of the stepper 6 more flexible and diverse. This allows for more precise fulfillment of the trainee's needs for training angles at different training stages, enhancing the functionality and practicality of the equipment.

[0037] like Figure 1 As shown, the support frame 2 includes two parallel columns 21 and a crossbeam 22 fixed to the upper ends of the two columns 21. The lower sides of the columns 21 are fixed to the base 1, and the aforementioned fixed pulleys 8 are respectively located on both sides of the crossbeam 22. This structure of the support frame 2 has good stability and load-bearing capacity, providing stable support for the pull rope 7 and the stepper 6. The combined structure of the two columns 21 and the crossbeam 22 ensures that the support frame 2 can maintain balance in both the vertical and horizontal directions, ensuring the overall stability of the equipment during rehabilitation training and providing a safe and reliable training environment for the trainee.

[0038] like Figure 5 As shown, the support column 21 includes an upper upright tube 211, a sleeve 212, and a lower upright tube 213. The lower side of the upper upright tube 211 and the upper side of the lower upright tube 213 are both located within the sleeve 212 and can slide relative to the sleeve 212 to adjust the height of the support column 21. Both the lower side of the upper upright tube 211 and the upper side of the lower upright tube 213 are equipped with fixing members. When the upper upright tube 211 slides to the target position, the fixing members secure it within the sleeve 212; when the lower upright tube 213 slides to the target position, the fixing members secure it within the sleeve 212; when both the upper upright tube 211 and the lower upright tube 213 slide to their respective target positions, the fixing members secure both the upper upright tube 211 and the lower upright tube 213 within the sleeve 212. This height-adjustable support column 21 structure allows for flexible adjustment of the support frame 2 according to the trainee's height and training needs. During adjustment, simply slide the upper riser 211 or lower riser 213 relative to the sleeve 212 to the appropriate position, and then fix it inside the sleeve 212 using the fasteners. The operation is simple and convenient. This height-adjustable design allows the equipment to better adapt to users of different heights, improving the equipment's versatility and adaptability. It ensures that the user is in the most comfortable position during training, thereby improving training effectiveness and user experience.

[0039] Specifically, the fixing component 3 consists of bolts and nuts. Specifically, the sleeve 212 has several limiting holes 2121 along the vertical direction. The lower side of the upper riser 211 and the upper side of the lower riser 213 each have two positioning holes 2111 with the same diameter as the limiting holes 2121. The distance between the two positioning holes 2111 is equal to the distance between two adjacent limiting holes 2121. The upper riser 211 and the lower riser 213 are fixed to the sleeve 212 by two bolts passing through the limiting holes 2121 and the positioning holes 2111 respectively. When it is necessary to adjust the height of the column 21, the bolts and nuts on the upper riser 211, or the bolts and nuts on the lower riser 213, or the bolts and nuts on both the upper riser 211 and the lower riser 213, can be removed for adjustment. The fastener can also be a V-shaped or arc-shaped spring and a column fixed on both sides of the spring. The end face of the column is spherical. One spring and two columns form a set. Specifically, the upper riser 211 and the lower riser 213 are respectively provided with two sets of springs corresponding to the positioning hole 2111 and columns corresponding to the springs. The columns pass through the upper riser 211 and the lower riser 213 through both sides of the positioning hole 2111. When only the upper riser 211 is slid, when the upper riser 211 slides until the column in the upper riser 211 corresponds to the limiting hole 2121, the column in the upper riser 211 slides into the limiting hole 2121 under the elastic force of the spring, fixing the upper riser 211 to the sleeve 212. When only the lower riser 213 is slid... When the lower riser 213 slides until the column inside the lower riser 213 corresponds to the limiting hole 2121, the column slides into the limiting hole 2121 under the action of the spring plate, fixing the lower riser 213 to the sleeve 212. When the upper riser 211 and the lower riser 213 are slid simultaneously for height adjustment, when the upper riser 211 slides until the column inside the upper riser 211 corresponds to the limiting hole 2121, the column inside the upper riser 211 slides into the limiting hole 2121 under the action of the spring plate, fixing the upper riser 211 to the sleeve 212. Similarly, under the action of the spring plate in the lower riser 213, the column inside the lower riser 213 slides into the limiting hole 2121, fixing the lower riser 213 to the sleeve 212.

[0040] Specifically, the upper upright 211, sleeve 212, and lower upright 213 are non-circular tubes, such as hollow triangular prisms or quadrangular prisms. This non-circular tube design effectively prevents the upright 21 from rotating during adjustment, thus ensuring the accuracy of the height adjustment direction. In practical use, when the trainee needs to adjust the height of the support frame 2, the non-circular tube structure ensures that the upright 21 slides smoothly along the predetermined axis, avoiding adjustment deviations caused by rotation. This further improves the stability and reliability of the equipment and simplifies the height adjustment process, allowing trainees or medical personnel to adjust the equipment more conveniently.

[0041] Specifically, the base 1 has fixing seats 9 on both sides. Each fixing seat 9 has a fixing groove 91 for inserting the lower end of the column 21. The fixing groove 91 has a shaft hole 92 that extends horizontally through both sides of the groove wall and several mounting holes 93 circumferentially distributed around the shaft hole 92. The lower upright tube 213 of the column 21 has a connecting hole 2131 and a fixing hole 2132 on its lower side. The distance between the connecting hole 2131 and the fixing hole 2132 is equal to the distance between the shaft hole 92 and any mounting hole 93. The lower upright tube 213 is rotatably connected to the fixing seat 9 via a rotating shaft passing through the connecting hole 2131, the shaft hole 92, and the fixing seat 9. When the support frame 2 rotates around the rotating shaft to any mounting hole 93 position, the fixing hole 2132 corresponds to that mounting hole 93. Bolts are passed through the mounting holes 93 and the fixing holes 2132, and nuts are used to fix the column 21 to the base 1. This design allows the support frame 2 to rotate around the rotating shaft and, after rotating to a suitable position, can be fixed to the base 1 with bolts and nuts. By providing multiple mounting holes 93, the support frame 2 offers several selectable fixing positions, allowing for flexible adjustment of the angle between the support frame 2 and the base 1 according to the trainee's physical condition and training needs. This adjustable angle design further enhances the device's personalization adaptability, enabling it to better meet the training requirements of different trainees and improving its functionality and practicality. Furthermore, when the rehabilitation training rack is not in use, the support frame 2 can be folded to fit snugly against the base 1, thus reducing the space occupied by the rehabilitation training rack.

[0042] Preferably, there are five mounting holes 93. Two mounting holes 93 are at the same horizontal level as the shaft hole 92, so that the support frame 2 can be folded toward the mounting base 4 or away from the mounting base 4. The line connecting the three mounting holes 93 to the shaft hole and the base forms angles of 60 degrees, 90 degrees and 120 degrees respectively. The trainee can adjust the support frame 2 to a position of 60 degrees, 90 degrees and 120 degrees with the base according to the training needs.

[0043] Specifically, the aforementioned stepper is not limited to being fixed on the base mentioned above; it can also be detached and fixed on other auxiliary rehabilitation frames, as long as a mounting bracket for the pull rope is provided above the base of the stepper, ensuring that the pull rope can slide relative to the mounting bracket. For example, it can be used on the support frame of the Chinese utility model patent "Rehabilitation Training Device" with patent publication number CN219814624U. Specifically, the stepper is fixed to the first support rod of the patent by bolts and nuts, and two traction components are set on the second support rod. Two pull ropes are respectively looped on the corresponding traction components. One end of the two pull ropes is connected to the left and right pedals of the stepper, respectively, and the other end of the two pull ropes is used to connect the left and right upper limbs of the trainee, respectively.

The column is fixed to the base by passing a bolt through the mounting hole and the fixing hole and then using a nut.
