Description

Technical Field

[0001] This invention belongs to the field of foot joint rehabilitation, specifically relating to a foldable foot pedal rebound exercise device for foot rehabilitation. Background Technology

[0002] Patients' feet suffer varying degrees of injury in daily life, especially during post-operative recovery, requiring effective rehabilitation exercises to achieve rapid foot health restoration. Currently, rehabilitation devices for the feet on the market have the following shortcomings: many devices only provide basic foot examinations or simple passive movement functions, lacking exercise components that allow patients to actively participate in resistance training, making it difficult to meet the comprehensive needs of different rehabilitation stages; the foot pedal components for exercise often permanently extend beyond the main body of the device, occupying significant space when not in use, which is inconvenient for storage and movement in home or hospital environments, and their complex structure and high cost make them unsuitable for widespread adoption in primary hospitals or patients' homes. Therefore, there is an urgent need for a foldable foot pedal rebound exercise device for foot rehabilitation. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing foot rehabilitation devices in the background art, which have limited functions, cannot meet the needs of patients for active exercise, and are inconvenient to store due to poor adjustability. The invention aims to realize a foldable foot pedal rebound exercise device for foot rehabilitation.

[0004] To achieve the above-mentioned objectives, the technical solution of this invention is: a foldable foot-operated rebound exercise device for foot rehabilitation, comprising a seat, multiple support legs fixedly installed on the underside of the seat, a rotating shaft rotatably installed on the underside of the front support leg, an assembly plate fixedly installed on the outer circumference of the rotating shaft, a track fixedly installed on the upper side of the assembly plate, two movable blocks slidably arranged along the length of the track, and a foot-operated rebound exercise component installed on the upper side of the movable blocks for subsequent foot-operated rehabilitation exercises for the patient's foot, a spacing adjustment component installed between the two movable blocks for adjusting the distance between the two movable blocks, and an angle adjustment component connected to the end of the rotating shaft to adjust the rotation of the rotating shaft to a suitable angle for folding or opening the foot-operated rebound exercise component.

[0005] Specifically, the angle adjustment component includes a side plate fixedly installed to the side of the seat. An installation plate is fixedly installed on the upper part of the side plate.

A telescopic rod is hinged to the lower part of the inner side of the connecting plate. A positioning cylinder is fixedly installed on the lower side of the installation plate. The telescopic rod is located inside the positioning cylinder and inserted into the positioning cylinder. A sliding plate is fixedly installed on the lower side of the telescopic rod. A placement plate is fixedly installed on the lower side of the side plate. The placement plate has a sliding groove. The sliding plate slides in the sliding groove. A lifting plate is fixedly installed on the side of the sliding plate near the side plate. A rack is fixedly installed at the lower end of the lifting plate. A gear is meshed with the rack. A first transmission shaft is fixedly installed in the middle of the gear. A transmission component is connected to the first transmission shaft. The transmission component is connected to a rotating shaft.

[0006] Specifically, the transmission component includes a protective housing fixedly installed with the support leg, a first transmission shaft rotatably connected to the protective housing, a second transmission shaft connected to the first transmission shaft via a bevel gear set, the second transmission shaft rotatably connected to the protective housing, and the second transmission shaft connected to a rotating shaft via a bevel gear set, the rotating shaft rotatably connected to the protective housing.

[0007] Specifically, the foot-operated rebound exercise component includes an upper connecting seat fixedly installed on the upper side of the moving block. Two parallel connecting rods are hinged to the upper sides of the upper connecting seat, and brackets are hinged to the outer sides of the two connecting rods. A pedal is fixedly installed on the side of the bracket away from the upper connecting seat, and an extension adjustment plate is hinged to the side of the pedal away from the connecting seat. A top seat is hinged to the upper side of the bracket, and a moving rod is fixedly installed on the lower side of the top seat. A base is hinged to the upper side of the upper connecting seat, and a long cylinder is fixedly installed on the upper side of the base. One side of the moving rod is located inside the long cylinder and can move freely along the length of the long cylinder. A spring is installed between the top seat and the base, and the spring is fitted onto the outer side of the moving rod and the long cylinder.

[0008] Specifically, a tension spring is installed between the extension adjustment plate and the pedal, and the extension adjustment plate, the pedal, and the tension spring all form a triangle when the extension adjustment plate is extended or retracted.

[0009] Specifically, the spacing adjustment component includes pull plates that are fixedly installed with the moving block. Each pull plate is threadedly connected to an adjusting screw. The two adjusting screws are fixedly connected and their outer sides are rotatably mounted with the assembly plate. An adjusting shaft is connected to the middle side of the two adjusting screws through a bevel gear set.

[0013] 1. This invention achieves the overall flipping of the foot pedal rebound exercise component through the cooperation of the angle adjustment component and the transmission component, which opens the foot pedal rebound exercise component and facilitates the exercise of the patient's foot joints. When the device is not in use, the foot pedal rebound exercise component can be folded under the seat, which greatly reduces the size of the device and makes it easy to store and move.

[0014] 2. By setting a spacing adjustment component, the present invention can easily adjust the distance between the two moving blocks, i.e. the foot pedal rebound exercise component, to adapt to the exercise needs of patients with different body types or different limb conditions, thereby improving the versatility and comfort of the device.

[0015] 3. This invention uses a foot-operated rebound exercise component, allowing patients to perform active foot-operated rehabilitation training while seated. This helps to strengthen the joints of the patient's feet, enhance the strength of the plantar muscles, and improve local blood circulation, making it suitable for subsequent rehabilitation treatment of the patient's foot joints.

[0028] The foldable foot-operated rebound exercise device for foot rehabilitation of the present invention will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0029] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0030] This embodiment discloses a foldable foot pedal rebound exercise device for foot rehabilitation, such as... Figure 1-7 As shown, the device includes a seat 1, with multiple support legs 2 fixedly installed on the lower side of the seat 1. A rotating shaft 13 is rotatably installed on the lower side of the front support legs 2. An assembly plate 10 is fixedly installed on the outer circumference of the rotating shaft 13. A track 7 is fixedly installed on the upper side of the assembly plate 10. Two moving blocks 11 are slidably arranged along the length of the track 7. A foot pedal rebound exercise component 6 is installed on the upper side of the moving blocks 11 for subsequent foot pedaling rehabilitation exercises for the patient's feet. A spacing adjustment component is installed between the two moving blocks 11 to adjust the distance between the two moving blocks 11. An angle adjustment component 3 is connected to the end of the rotating shaft 13 to adjust the rotating shaft 13 to rotate to a suitable angle for the foot pedal rebound exercise component 6 to retract or expand.

[0031] First, the patient sits on the seat board 1 with both feet placed on the two foot pedal rebound exercise components 6. During rehabilitation exercises, the angle adjustment component 3 drives the rotating shaft 13 to rotate, which in turn drives the mounting plate 10 to rotate around the axis of the shaft 13. This opens the track 7, the moving block 11, and the entire foot pedal rebound exercise component 6 from the retracted position to the predetermined working angle. Then, according to the natural distance between the patient's feet, the distance adjustment component is operated to drive the two moving blocks 11 to slide towards or away from each other on the track 7, thereby adjusting the lateral distance between the two foot pedal rebound exercise components 6. After adjustment, the patient can perform foot pedaling rehabilitation exercises. The foot pedal rebound exercise component 6 provides rebound resistance opposite to the pedaling force, achieving the purpose of exercising the foot joints and foot muscles. After treatment or exercise, the angle adjustment component 3 rotates the entire foot pedal rebound exercise component 6 in the opposite direction to retract it to the retracted position.

[0032] like Figure 7 As shown, the angle adjustment component 3 includes a side plate 9 fixedly installed to the side of the seat plate 1. A mounting plate 304 is fixedly installed on the upper part of the side plate 9. A lifting plate 302 is hinged to the upper side of the mounting plate 304. A connecting plate 303 is hinged to the outer side of the middle of the lifting plate 302. A telescopic rod 305 is hinged to the lower inner part of the connecting plate 303. A positioning cylinder 306 is fixedly installed on the lower side of the mounting plate 304. The telescopic rod 305 is located inside the positioning cylinder 306 and inserted into it. The lower side of the telescopic rod 305 is fixedly mounted... The slide plate 307 is equipped with a placement plate fixedly installed on the lower side of the side plate 9. The placement plate has a sliding groove, and the slide plate 307 slides in the sliding groove. A lifting plate is fixedly installed on the side of the slide plate 307 near the side plate 9. A rack 308 is fixedly installed at the lower end of the lifting plate. The rack 308 is meshed with a gear 309. A first transmission shaft is fixedly installed in the middle of the gear 309. The first transmission shaft is connected to a transmission component 4. The transmission component 4 is connected to a rotating shaft 13. A handle 301 is fixedly installed at the upper end of the lifting plate 302.

[0033] When the angle of the foot pedal rebound exercise component 6 needs to be adjusted, the operator presses down on the lifting plate 302. The lifting plate 302 rotates around the hinge point with the mounting plate 304, causing the connecting plate 303 to move downward. The connecting plate 303 then pulls the telescopic rod 305 to slide downward within the positioning cylinder 306. The telescopic rod 305 drives the lifting plate and the rack 308 fixed at its lower end to move downward together through the sliding plate 307. The downward movement of the rack 308 drives the gear 309 meshing with it to rotate. The rotation of the gear 309 drives the first transmission shaft to rotate. The first transmission shaft transmits power to the subsequent transmission component 4, which ultimately drives the rotating shaft 13 to rotate, realizing the unfolding of the foot pedal rebound exercise component 6. Conversely, pulling the lifting plate 302 upward realizes the folding down of the foot pedal rebound exercise component 6.

[0034] The transmission component 4 includes a protective housing 5 fixedly mounted to the support leg 2. A first transmission shaft is rotatably connected to the protective housing 5. The first transmission shaft is connected to a second transmission shaft 14 via a bevel gear set. The second transmission shaft 14 is rotatably connected to the protective housing 5. The second transmission shaft 14 is connected to a rotating shaft 13 via a bevel gear set. The rotating shaft 13 is rotatably connected to the protective housing 5. The first transmission shaft drives the second transmission shaft 14 to rotate via the bevel gear set. The second transmission shaft 14 drives the rotating shaft 13 to rotate via the bevel gear set. The protective housing 5 provides rotational support for the first transmission shaft, the second transmission shaft 14, and the rotating shaft 13. The combination of the two sets of bevel gear sets and the first transmission shaft, the second transmission shaft 14, and the rotating shaft 13 realizes the reversal of power in space and long-distance transmission.

[0035] like Figure 3 He Ru Figure 4 As shown, the foot-operated rebound exercise component 6 includes an upper connecting seat 606 fixedly mounted to the upper side of the moving block 11. Two parallel connecting rods 605 are hinged to the upper sides of the upper connecting seat 606. A bracket 603 is hinged to the outer side of each connecting rod 605. A pedal 602 is fixedly mounted on the side of the bracket 603 away from the upper connecting seat 606. An extension adjustment plate 601 is hinged to the side of the pedal 602 away from the connecting seat 606. A top seat 609 is hinged to the upper side of the bracket 603. A moving rod 608 is fixedly mounted on the lower side of the top seat 609. A base 610 is hinged to the upper side of the upper connecting seat 606. A long cylinder 607 is fixedly mounted on the upper side of the base 610. One side of the moving rod 608 is located inside the long cylinder 607 and moves freely along the length of the long cylinder 607. A spring is installed between the top seat 609 and the base 610, and the spring is fitted onto the outer side of the moving rod 608 and the long cylinder 607. An adjusting nut 611 is threadedly connected to the outer circumference of the long cylinder 607 near the base 610. The upper side of the adjusting nut 611 is connected to the spring through a circular washer. The washer can move freely along the length of the long cylinder 607. When the adjusting nut 611 is tightened clockwise, the adjusting nut 611 moves along the long cylinder 607 toward the spring, and then drives the spring to move away from the base 610 through the washer. Thus, by changing the original stroke of the spring, that is, changing the initial compression of the spring, it can adapt to the exercise intensity required by different patients.

[0036] The patient steps down on pedal 602 or extension adjustment plate 601, causing pedal 602 to swing downwards via bracket 603 and two parallel connecting rods 605. The downward swing of bracket 603 causes top seat 609 to move downwards, compressing the springs on the outside of moving rod 608 and long cylinder 607. Simultaneously, moving rod 608 retracts into long cylinder 607, ensuring directional movement. When the patient lifts their foot to release the force, the compressed springs return to their original shape, pushing top seat 609, bracket 603, and pedal 602 back upwards. This process is repeated to complete one resistance pedaling exercise. The two sets of parallel connecting rods 605 ensure that pedal 602 remains parallel to its initial state throughout the up-and-down movement. The springs provide variable, gentle rebound resistance, avoiding rigid impact and making foot rehabilitation exercises safer for patients.

[0037] A tension spring 604 is installed between the extension adjustment plate 601 and the pedal 602. The extension adjustment plate 601, the pedal 602, and the tension spring 604 form a triangle when the extension adjustment plate 601 is in the extended or retracted state. The tension spring 604 here automatically keeps the extension adjustment plate 601 in a fixed state after it is opened or retracted, and it will not be folded or bent at will due to gravity or vibration, making it more reliable.

[0038] like Figure 5 He Ru Figure 6 As shown, the spacing adjustment component includes pull plates that are fixedly installed with the moving block 11. Both pull plates are threadedly connected to adjusting screws 8. The two adjusting screws 8 are fixedly connected and their outer sides are rotatably disposed with the mounting plate 10. The middle sides of the two adjusting screws 8 are connected to adjusting shafts through bevel gear sets. The adjusting shafts are rotatably disposed with the mounting plate 10. Adjusting nuts 12 are fixedly installed on the upper end of the adjusting shafts. The threads of the two adjusting screws 8 have opposite directions.

[0039] When it is necessary to adjust the distance between the two foot pedals 602, use a tool or your hand to turn the adjusting nut 12. The adjusting nut 12 drives the adjusting shaft to rotate. The adjusting shaft transmits the rotational power to the adjusting screw 8, which consists of two sections of opposite threads, through a bevel gear set. When the adjusting screw 8 rotates, since the two sections of threads are in opposite directions, the two pull plates connected to it will drive their respective moving blocks 11 to move in opposite directions along the track 7, that is, to move closer or further away at the same time. This achieves synchronous and equidistant adjustment of the foot pedal distance. It realizes that only one adjusting nut 12 is needed to drive the synchronous and symmetrical movement of the two foot pedals 602. It has the functions of high adjustment accuracy and fast speed, ensuring that the two feet are always symmetrically distributed around the center line of the seat 1, which conforms to human biomechanics.

[0040] Both sides of the seat board 1 are fixedly equipped with armrests, and the backrest is integrally connected to the rear side of the seat board 1. When the patient sits on the seat board 1, his back can be supported by the backrest, and his hands can be placed on the armrests on both sides to maintain body stability and facilitate smooth foot pedaling exercises.

[0041] The length of the mounting plate 10 is less than the distance between the two front support legs 2, ensuring that the entire foot pedal exercise component can be folded into the space under the seat 1. When the mounting plate 10 is flipped upward to near horizontal by the angle adjustment component 3, since its length is less than the distance between the two support legs 2, it can be accommodated between the two front support legs 2 without interference, making the folded state more compact and flat, avoiding structural protrusion, and optimizing the storage effect and overall appearance of the device.

[0042] In use, the device is first placed on a flat, solid surface. All components are checked for integrity. The patient rests their back against the backrest, with their hands lightly holding the armrests on either side for stability. During rehabilitation exercises, the angle adjustment component 3 and transmission component 4 work together to drive the rotating shaft 13. The shaft 13 drives the assembly plate 10 to rotate around its axis, opening the track 7, moving blocks 11, and the entire foot-pedal rebound exercise component 6 from the retracted position to a predetermined working angle. Then, based on the patient's natural foot spacing, the spacing adjustment component is operated to drive the two moving blocks 11 to slide towards or away from each other on the track 7, adjusting the lateral distance between the two foot-pedal rebound exercise components 6. After adjustment, the patient can perform foot-pedaling rehabilitation exercises. The foot-pedal rebound exercise component 6 provides rebound resistance opposite to the stepping force, achieving the purpose of exercising the foot muscles. After treatment or exercise, the angle adjustment component 3 and transmission component 4 work together to rotate the entire foot-pedal rebound exercise component 6 back to the retracted position.
