Description

Technical Field

[0001] This invention relates to the field of rehabilitation training technology, and more specifically, to a multifunctional training device for sports injury rehabilitation. Background Technology

[0002] Rehabilitation training aims to gradually restore an athlete's dynamic balance and coordination on the field. Complete foot immobilization weakens the neuromuscular system's ability to adapt to dynamic environments. Therefore, restraints provide moderate fixation, allowing for safe micro-movements of the ankle, distributing pressure, and reducing excessive load on individual joints. For example, when an athlete pedals, the ankle can naturally adjust its angle to adapt to the pedal's trajectory, reducing the risk of joint injury.

[0003] However, as training intensity increases, when the athlete's foot is at the highest point of pedal rotation, the pressure exerted on the pedal by the foot increases, which can easily cause slippage between the foot and the pedal. At this time, the foot is in a tilted state, resulting in longitudinal slippage, which reduces training efficiency and affects the athlete's athletic performance and movement stability. Summary of the Invention

[0004] This invention provides a multifunctional training device for sports injury rehabilitation, which provides support for the front of the foot by supporting the foot pedal and tightening the restraint strap, thereby solving the problem mentioned in the background art, namely: the foot is in an inclined state and longitudinal sliding occurs.

[0005] To achieve the above objectives, a multifunctional training device for sports injury rehabilitation includes a support frame, a seat back, a handle, and a flywheel assembly. Anti-slip foot pedals are provided on both sides of the flywheel assembly, and locking components are provided on both sides of the anti-slip foot pedals. The locking components secure the feet to the anti-slip foot pedals by fixing the two ends of the restraint straps.

[0006] A longitudinal movement zone is formed between the binding strap on both sides and the foot. A support mechanism is movably installed at the front end of the anti-slip foot pedal surface. The support mechanism is used to support the forefoot and limit the lateral displacement between the forefoot and the anti-slip foot pedal. When the training intensity increases, the forefoot applies pressure to the support mechanism, driving it to rotate and press down. An extension mechanism is provided on both sides of the support mechanism, located inside the binding strap. The downward pressure of the support mechanism causes the extension mechanisms on both sides to move longitudinally, thereby tightening the foot and reducing the longitudinal movement zone to firmly bind the foot to the anti-slip foot pedal.

[0007] The locking component includes a guide plate and a limiting buckle fixed to the anti-slip foot pedal. The guide plate is located above the limiting buckle and has a slot for the restraint strap to pass through. One end of the restraint strap is fixed to one of the limiting buckles, and the other end is fitted onto another limiting buckle. The restraint strap has several square holes.

[0008] The load-bearing mechanism includes a support pedal that is rotatably mounted on the anti-slip foot pedal. The support pedal is fan-shaped and has an arc surface and two cut surfaces. One of the cut surfaces has an anti-slip groove that corresponds to the front end of the foot to support the foot. The anti-slip foot pedal has a notch with the same radius as the support pedal.

[0009] Stops are fixedly installed on both sides of the support pedal. The stops extend outward and block the wedge block installed below.

[0010] An arc-shaped groove corresponding to the stop block is provided on the anti-slip foot pedal. The arc-shaped groove and the support pedal are on the same axis. A slider is symmetrically fixed on one side of the wedge block. The anti-slip foot pedal corresponding to the slider has a T-shaped groove.

[0011] The extension mechanism includes an extension plate and an extension block disposed on the outside of the anti-slip foot pedal. The extension plate and the extension block are both located inside the restraint strap, and the restraint strap is pushed outward by longitudinal displacement. The extension block is fixed to one end of the extension plate, and the other end of the extension plate extends to the bottom of the wedge block.

[0012] An auxiliary rod is fixedly installed on the anti-slip foot pedal. The auxiliary rod extends through the outer plate below the wedge block and is slidably connected to the outer plate.

[0013] A tension spring is elastically connected between the anti-slip foot pedal and the outer extension plate, and the tension spring is sleeved on the auxiliary rod.

[0014] The wedge block has a guide surface with a sunken end and a raised end. Under normal conditions, the outer plate is in the sunken end position. When the wedge block moves down, the guide surface pushes the outer plate outward by squeezing, causing the restraint band to expand outward, thereby reducing the longitudinal movement area and restraining the sides of the foot.

[0015] The extension block is arc-shaped with a semi-circular cross-section that contacts the binding strap. Two rollers are provided in the groove of the guide plate. The binding strap passes through the gap between the rollers on both sides, and the extension block is located on the path through which the binding strap passes.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] This multifunctional training device for sports injury rehabilitation uses a support pedal to support the front of the foot. On the one hand, it increases the pressure between the foot and the anti-slip foot pedal and the support pedal, making the foot fit more closely with them and providing more stable support for the athlete. On the other hand, by tightening the restraint straps, the longitudinal movement zone is reduced, which effectively restrains the sides of the foot and limits the tendency of the foot to slide to the sides, effectively improving the anti-slip effect, thereby ensuring a stable posture and force exertion during training.

[0031] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0032] Therefore, to address the issue of slippage between the foot and the foot pedal, this invention provides a multifunctional training device for sports injury rehabilitation, referencing... Figures 1-2As shown, the device includes a support frame 100, a seat back 101, a handle 102, and a flywheel assembly 103. Anti-slip footrests 110 are provided on both sides of the flywheel assembly 103. The seat back 101 is capable of moving in the lateral direction (where the lateral direction is...). Figure 2 The direction indicated by the middle arrow is vertical. Figure 7 (As shown by the middle arrow), this is to accommodate people of different heights; during rehabilitation training, the athlete first adjusts the distance of the seat back 101, then sits on the seat back 101, with both feet on the non-slip foot pedals 110, and hands on the handles 102, and then, combined with... Figure 3 , Figure 4 As shown, locking devices are provided on both sides of the anti-slip foot pedal 110. The locking devices fix the two ends of the restraint strap 104 to bind the foot to the anti-slip foot pedal 110, preventing the foot from loosening and affecting training.

[0033] First, when securing the restraint strap 104, the locking mechanism includes a guide plate 111 and a limiting buckle 112 fixed to the anti-slip foot pedal 110. The guide plate 111 is located above the limiting buckle 112, and has a slot for the restraint strap 104 to pass through. One end of the restraint strap 104 is fixed to one of the limiting buckles 112, and the other end is fitted onto the other limiting buckle 112. The restraint strap 104 also has several square holes. Thus, before the foot is placed on the anti-slip foot pedal 110, the restraint strap... One end of the strap 104 is fixed, while the other end is in a released state. After the foot steps on the anti-slip foot pedal 110, the strap 104 wraps around the surface of the foot and then passes through the groove of the guide plate 111 at the other end. Finally, the square hole on the strap 104 is fastened to the limit buckle 112, so that the foot is bound to the anti-slip foot pedal 110, initially restricting the sliding between the foot and the anti-slip foot pedal 110. In addition, the anti-slip foot pedal 110 also has anti-slip grooves to increase the friction between the foot and the anti-slip grooves.

[0034] Secondly, longitudinal movement zones 113 are formed on both sides of the restraint strap 104 between the foot and the forefoot. A support mechanism 120 is movably installed at the front end of the anti-slip foot pedal 110. The support mechanism 120 supports the forefoot and restricts lateral displacement between the foot and the anti-slip foot pedal 110. When the training intensity increases, the forefoot applies pressure to the support mechanism 120, driving it to rotate and press down. At this time, extension mechanisms 130 located inside the restraint strap 104 are provided on both sides of the support mechanism 120. The downward pressure of the support mechanism 120 causes the extension mechanisms 130 on both sides to move longitudinally, thereby tightening the foot and reducing the longitudinal movement zone 113 to firmly bind the foot to the anti-slip foot pedal 110. The specific process is shown below:

[0035] The support mechanism 120 includes a support pedal 121 rotatably mounted on the anti-slip foot pedal 110. The support pedal 121 is fan-shaped, with an arc surface and two cut surfaces. One of the cut surfaces has an anti-slip groove corresponding to the front of the foot to support the foot. The anti-slip foot pedal 110 has a notch with the same radius as the support pedal 121 (see reference). Figure 7 (As shown in the dotted line portion); Thus, when the foot steps on the anti-slip pedal 110, the front of the foot contacts the anti-slip groove on one of the cut surfaces, and the support pedal 121 supports the front part of the foot. Then, the rear of the foot contacts the anti-slip groove on the anti-slip pedal 110. Following the fixing steps of the restraint strap 104 described above, the restraint strap 104 fixes the foot to the anti-slip pedal 110. At this time, due to the pressure of the foot, the support pedal 121 will... Figure 5 As indicated by the middle arrow, rotating counterclockwise will cause part of the support pedal 121 to rotate into the notch.

[0036] In the initial state, the supporting pedal 121 is as follows: Figure 5 As shown, immediately following the rotation of the support pedal 121, stop blocks 123 are fixedly installed on both sides of the support pedal 121. The stop blocks 123 extend outward and block the wedge block 122 installed below; on the other hand, combined with Figure 6 , Figure 7 As shown, an arc-shaped groove 115 corresponding to the stop block 123 is provided on the anti-slip foot pedal 110. The arc-shaped groove 115 and the support pedal 121 are on the same axis. A slider is symmetrically fixed on one side of the wedge block 122. The anti-slip foot pedal 110 corresponding to the slider has a T-shaped groove 116. Therefore, during the rotation of the support pedal 121, the two support pedals 121 drive the stop block 123 to rotate synchronously. The stop block 123 slides along the trajectory of the arc-shaped groove 115. Since the stop block 123 blocks the wedge block 122, the stop block 123 pushes the wedge block 122 downward by applying pressure to the wedge block 122. The sliders on both sides slide in the T-shaped groove 116 to keep the T-shaped groove 116 stable, so that the wedge block 122 moves downward.

[0037] The extension mechanism 130 consists of an extension plate 131 and an extension block 132 located on the outside of the anti-slip foot pedal 110. Both the extension plate 131 and the extension block 132 are located in the inner area of ​​the restraint strap 104. The two can push the restraint strap 104 outward through the thrust generated by the longitudinal displacement, thereby adjusting the position of the restraint strap 104 and tightening the restraint strap 104.

[0038] The extension block 132 is fixed to one end of the extension plate 131, and the other end of the extension plate 131 extends to the lower position of the wedge block 122. An auxiliary rod 133 is provided on the anti-slip foot pedal 110. The auxiliary rod 133 extends through the part of the extension plate 131 below the wedge block 122, and the auxiliary rod 133 and the extension plate 131 are slidably connected, so that the extension plate 131 can move longitudinally under the guidance of the auxiliary rod 133.

[0039] Furthermore, combined with Figure 8 It can be seen that the anti-slip foot pedal 110 and the outer extension plate 131 are elastically connected by a tension spring 134, and the tension spring 134 is sleeved on the auxiliary rod 133. In the initial state, the tension spring 134 is in a contracted state. At this time, the outer extension plate 131 abuts against the extension block 132, and the elastic potential energy stored in the tension spring 134 restricts the downward movement of the wedge block 122. At the same time, because the wedge block 122 resists the stop block 123, the support pedal 121 can be stably maintained at its position. Figure 5 The state shown.

[0040] When the foot applies pressure to the support pedal 121, the wedge block 122 has a guide surface with two parts: a recessed end and a raised end. Under normal conditions, the extension plate 131 is in the recessed end position, and the entire device is in a stable state.

[0041] Then, as the wedge block 122 moves downward, the guide surface applies pressure to the extension plate 131, causing the guide surface to make extrusion contact with the extension plate 131 during the downward movement of the wedge block 122. The extrusion pushes the extension plate 131 outward. At the same time, the slider stabilizes the wedge block 122, preventing it from shifting during the downward movement and ensuring its stability.

[0042] After the wedge block 122 pushes the extension plate 131 outward, the restraint band 104 expands outward, which in turn reduces the space of the longitudinal movement zone 113, thereby achieving restraint on both sides of the foot, providing athletes with more stable and reliable support and fixation during training, and ensuring force exertion and balance during exercise.

[0043] Next, the extension block 132 is set to be arc-shaped, with a semi-circular cross-section that contacts the binding strap 104. Two rollers 114 are provided in the groove of the guide plate 111, and the binding strap 104 passes through the space between the two rollers 114. The extension block 132 is located on the path through which the binding strap 104 passes. As the wedge block 122 moves downward, the extension plate 131 moves along the guide surface... Figure 8The center arrow moves outward, and with the restriction of the rollers 114 on both sides, the binding strap 104 above the foot tightens, and the longitudinal movement zone 113 formed on both sides of the foot also contracts. This increases the pressure between the foot and the anti-slip foot pedal 110 and the support pedal 121, while also restricting the foot from sliding to the sides and improving the anti-slip effect.

[0044] The extension block 132 is set to be arc-shaped with a semi-circular cross-section, so that it can contact the binding strap 104 and expand the binding strap 104 outward. At the same time, two rollers 114 are provided in the slot of the guide plate 111, and the binding strap 104 passes through the gap between the two rollers 114. The extension block 132 is located on the path through which the binding strap 104 passes, so that the extension block 132 expands the binding strap 104 outward.

[0045] When the wedge block 122 moves downward, under the action of the guide surface, the extension plate 131 moves according to... Figure 8 The direction indicated by the middle arrow moves outward. At this time, due to the restriction of the two sides of the binding strap 104 by the roller 114, the outward movement of the extension plate 131 will cause the binding strap 104 located above the foot to gradually tighten. At the same time, the longitudinal movement area 113 formed on both sides of the foot will also contract synchronously.

[0046] In other words, by using the support pedal 121 to support the front of the foot, on the one hand, it can increase the pressure between the foot and the anti-slip foot pedal 110 and the support pedal 121, making the foot fit more closely with them and providing more stable support for the athlete; on the other hand, by tightening the restraint strap 104, the space of the longitudinal movement zone 113 is reduced to effectively restrain the sides of the foot, restricting the tendency of the foot to slide to the sides, effectively improving the anti-slip effect, thereby ensuring a stable posture and force exertion during training.

[0047] Once training is complete, simply remove the two side straps 104 from the soles of your feet.
