Description

Technical Field

[0001] This invention belongs to the field of training equipment technology, and in particular relates to a sports rehabilitation training device. Background Technology

[0002] Sports rehabilitation training equipment is a device specifically designed to restore motor function and improve physical function. It is widely used in rehabilitation medicine, sports training, community health and other scenarios.

[0003] Existing sports rehabilitation training equipment has relatively limited functionality; each piece of equipment can only target one body part for training and cannot provide multi-dimensional exercise training, thus limiting its effectiveness. Furthermore, most existing training equipment achieves different intensities of stress on body parts for rehabilitation training through weights or springs of varying sizes.

[0004] While weights allow for precise adjustment of training intensity based on the trainee's actual needs, improper movement patterns can lead to the use of momentum and body swaying to complete movements instead of engaging the target muscle groups. Long-term incorrect training not only fails to effectively build muscle but may also cause joint injuries due to abnormal stress and even lead to incorrect muscle memory. Furthermore, weights can become damaged from impacts and are difficult to store after prolonged use.

[0005] The expansion and contraction of a spring can lead to unstable intensity during training. The changes in the spring's expansion and contraction cause its force to change continuously, which can increase the burden on the joints that need rehabilitation training during the training process, making it difficult to achieve the purpose of rehabilitation training.

[0006] In addition, most of the existing sports rehabilitation training equipment is not easy to fold and store, making it inconvenient for home use, and it occupies activity space and affects people's activities when not in use.

[0007] This invention designs a sports rehabilitation training device to solve the above problems. Summary of the Invention

[0015] In one embodiment, one end of the second pull rope is guided by a first guide wheel located at the corner of the vertical rod and the insertion rod to be connected horizontally to the end of the second sliding column.

[0018] In one embodiment, the limiting structure includes a wheel seat disposed on the mounting frame, and fixed pulleys distributed around the fourth pull rope are disposed on the wheel seat. The center of the rim of the fixed pulley is provided with a first rope groove that cooperates with the fourth pull rope. Two conical tooth surfaces are symmetrically disposed on both sides of the first rope groove. The conical tooth surfaces on any two adjacent fixed pulleys mesh with each other, and the first rope grooves on the four fixed pulleys form a 360-degree surround on the fourth pull rope.

[0019] In one embodiment, the resistance assembly includes a housing mounted on a vertical rod. Within the housing, a third gear, a first variable-diameter wheel, a second variable-diameter wheel, a third variable-diameter wheel, and a fourth variable-diameter wheel are coaxially arranged via a tenth rotating shaft. Each of the first, second, third, and fourth variable-diameter wheels has a threaded sleeve on its surface. The threaded sleeve is connected to a fixing rod located at the top of the housing via a fourth spring. A locking screw that engages with a third slot on the tenth rotating shaft is located within the threaded sleeve. The first, second, third, and fourth variable-diameter wheels... Each of the fourth variable diameter wheels has a support ring on its surface to effectively stretch the corresponding fourth spring. The third gear meshes with a rack that slides vertically in a guide hole in the housing. The rack is connected to a push rod, which is connected to a top block located at the bottom of the energy storage sleeve on the outside of the housing. The top block is connected to a pressure block located at the top of the energy storage sleeve via a third spring. The pressure block has a pointer for indicating four graduations on the energy storage sleeve. The four graduations on the energy storage sleeve, from top to bottom, correspond one-to-one with the first, second, third, and fourth variable diameter wheels. The energy storage sleeve has an adjusting bolt that mates with the pressure block inside a threaded hole at its top. Second rope grooves are provided on the rims of the first, second, third, and fourth variable-diameter wheels. The minimum winding radius of the second rope grooves on these wheels is equal to the radius of the third gear. A fifth pull rope is provided in the second rope grooves of each wheel, with one end of the fifth pull rope connected to the end face at the maximum radius of the corresponding second rope groove. The other end is guided by the third guide wheel set on the corresponding fixed rod and passes through the rope hole on the top of the housing to be connected to the pull block on the upper side of the housing in a vertical state. Each of the four pull blocks is provided with a second insertion hole. The four second insertion holes correspond one-to-one with the first insertion hole of the connecting sleeve and are fitted with a pin. The radius of the second rope groove of the first variable diameter wheel, the second variable diameter wheel, the third variable diameter wheel and the fourth variable diameter wheel is proportional to the ratio of the rotation angle of the corresponding variable diameter wheel to the initial compression of the corresponding position of the third spring. The housing is provided with a switching port to facilitate the engagement of the screwdriver and the locking screw.

[0020] The beneficial effects of this invention are: 1. The first training component and the second training component in this invention can be disassembled and folded for storage. They can be placed in public places or used at home, expanding their application scenarios. When not in use, this invention can be stored away without taking up too much space, making it easier to free up more activity space for people.

[0021] 2. The present invention can provide three training modes: shoulder training, waist training and leg training through the first training component and the second training component. After the first training component and the second training component are assembled together, the resistance component in the first training component can be used to carry out rehabilitation training of different intensities for the shoulder, waist or legs as needed. This overcomes the shortcomings of traditional training equipment with single function and is conducive to people carrying out multi-dimensional exercise rehabilitation training on the same equipment, which greatly improves the efficiency of people's rehabilitation training.

[0022] 3. The resistance component in the second training component of this invention provides four levels of training intensity to the rehabilitation trainee simply by adjusting the compression of a third spring. The preset compression and corresponding elasticity changes of the third spring at each level are matched with the diameter change patterns of the first, second, third, and fourth variable-diameter wheels, ensuring that the resistance output of the resistance component remains constant at each level. This guarantees that the trainee receives a consistent training intensity at each level, preventing the user from unconsciously using inertia or body swaying to "borrow" force to complete movements due to non-standard movement patterns. This facilitates the activation of target muscle groups and joints, preventing injuries caused by abnormal joint stress. Compared to the traditional method of providing training intensity through weights, the resistance component is smaller and lighter, and more convenient, effectively overcoming the disadvantages of using weights to provide training intensity.

[0023] 4. The present invention effectively overcomes the problem of mismatch between the extension distance of the fourth pull rope and the extension distance of the third spring in the resistance component by means of the transmission structure set on the crossbeam of the second training component. This makes the third spring have a smaller compression distance when the fourth pull rope has a large pull distance, which helps to reduce the overall volume of the second training component and makes it easier for the second training component to occupy less space after being folded and stored.

A third synchronous belt 241 is connected between 43. A seventh pulley 245 is provided on the fifth rotating shaft 244. A fourth synchronous belt 246 is connected between the seventh pulley 245 and the eighth pulley 247, which is provided on the mounting frame 226 via the sixth rotating shaft 248. A ninth pulley 249 is provided on the sixth rotating shaft 248. A fifth synchronous belt 250 is connected between the ninth pulley 249 and the tenth pulley 251, which is provided on the mounting frame 226 via the seventh rotating shaft 252. An eleventh pulley 253 is provided on the seventh rotating shaft 252. A sixth synchronous belt 254 is connected between the eleventh pulley 253 and the twelfth pulley 255, which is provided on the mounting frame 226 via the eighth rotating shaft 256. A thirteenth pulley 257 is provided on the eighth rotating shaft 256. The thirteenth pulley 257 is connected to the fourteenth pulley 259 via the seventh synchronous belt 258.

[0036] In a further embodiment, such as Figure 22As shown, the transmission ratio of the first gear 229 to the second gear 230 is 1:2; the diameter ratio of the first pulley 232 to the second gear 230 is 2:1; the transmission ratio of the first pulley 232 to the second pulley 233 is 1:2; the diameter ratio of the second pulley 233 to the third pulley 236 is 1:2; the transmission ratio of the third pulley 236 to the fourth pulley 238 is 1:2; the diameter ratio of the fourth pulley 238 to the fifth pulley 240 is 1:2; the transmission ratio of the fifth pulley 240 to the sixth pulley 243 is 1:2; the diameter ratio of the sixth pulley 243 to the seventh pulley 245 is 1:2; and the transmission ratio of the seventh pulley 245 to the eighth pulley 247 is 1:2. The diameter ratio of the eighth pulley 247 to the ninth pulley 249 is 1:2. The transmission ratio of the ninth pulley 249 to the tenth pulley 251 is 1:2. The diameter ratio of the tenth pulley 251 to the eleventh pulley 253 is 1:2. The transmission ratio of the eleventh pulley 253 to the twelfth pulley 255 is 1:2. The diameter ratio of the twelfth pulley 255 to the thirteenth pulley 257 is 1:2. The transmission ratio of the thirteenth pulley 257 to the fourteenth pulley 259 is 1:2. The diameter of the fourteenth pulley 259 is smaller than the winding diameter of the second winding wheel 261. This ensures that the variable diameter wheel has a small rotation angle when the fourth pull rope 262 is pulled for a long time, while a portion of the fifth pull rope 292 is still wound on the variable diameter wheel.

[0037] In a further embodiment, such as Figures 19-21 As shown, the limiting structure 264 includes a wheel seat 265 disposed on the mounting frame 226. The wheel seat 265 is provided with fixed pulleys 266 distributed around the fourth pull rope 262. The center of the rim of the fixed pulley 266 is provided with a first rope groove 267 that cooperates with the fourth pull rope 262. Two conical tooth surfaces 268 are symmetrically arranged on both sides of the first rope groove 267. The conical tooth surfaces 268 on any two adjacent fixed pulleys 266 mesh with each other. The first rope grooves 267 on the four fixed pulleys 266 form a 360-degree surround of the fourth pull rope 262.

[0038] In a further embodiment, such as Figures 13-18As shown, the resistance assembly 269 includes a housing 270 mounted on a vertical rod 203. Within the housing 270, a third gear 274, a first variable-diameter wheel 282, a second variable-diameter wheel 283, a third variable-diameter wheel 284, and a fourth variable-diameter wheel 285 are coaxially mounted via a tenth rotating shaft 272. Each of the first variable-diameter wheel 282, the second variable-diameter wheel 283, the third variable-diameter wheel 284, and the fourth variable-diameter wheel 285 has a threaded sleeve 287 on its surface. The threaded sleeve 287 is connected to a fixing rod 289 located at the top of the housing 270 via a fourth spring 288. A locking screw 291 is provided within the threaded sleeve 287 to engage with a third slot 273 on the tenth rotating shaft 272. The first variable-diameter wheel 282, the second variable-diameter wheel 283, and the third variable-diameter wheel... Both wheel surfaces of 284 and the fourth variable diameter wheel 285 are provided with support rings 286 to effectively stretch the corresponding fourth spring 288. The third gear 274 meshes with a rack 275 that slides vertically in a guide hole on the housing 270. The rack 275 is connected to a push rod 276, which is connected to a top block 277 located at the bottom of the energy storage sleeve 278 located outside the housing 270. The top block 277 is connected to a pressure block 280 located at the top of the energy storage sleeve 278 via a third spring 279. A pointer 295 is connected to the pressure block 280 to indicate four graduations on the energy storage sleeve 278. The four graduations on the energy storage sleeve 278, from top to bottom, are respectively connected to the first variable diameter wheel 282, the second variable diameter wheel 283, the third variable diameter wheel 284, and the fourth variable diameter wheel 288. Each of the variable diameter wheels 285 corresponds to a pressure block 280. An adjusting bolt 281, which mates with the pressure block 280, is installed in the threaded hole at the top of the energy storage sleeve 278. Second rope grooves 296 are provided on the rims of the first, second, third, and fourth variable diameter wheels 282, 283, 284, and 285. The minimum winding radius of the second rope grooves 296 on each of these wheels is equal to the radius of the third gear 274. A fifth pull rope 292 is installed in the second rope grooves 296 of each of the first, second, third, and fourth variable diameter wheels 282. One end of the fifth pull rope 292 is connected to the corresponding second rope groove 296. The end face is connected at the large radius, and the other end is guided by the third guide wheel 290 set on the corresponding fixed rod 289 and passes through the rope hole at the top of the housing 270 to connect vertically to the pull block 293 on the upper side of the housing 270. Each of the four pull blocks 293 is provided with a second insertion hole 294. The four second insertion holes 294 correspond one-to-one with the first insertion hole 217 of the connecting sleeve 216 and are fitted with a pin 218. The radius of the second rope groove 296 of the first variable diameter wheel 282, the second variable diameter wheel 283, the third variable diameter wheel 284 and the fourth variable diameter wheel 285 is proportional to the ratio of the rotation angle of the corresponding variable diameter wheel to the initial compression amount of the corresponding gear of the third spring 279. The housing 270 is provided with a switching port 271 to facilitate the engagement of the screwdriver and the locking screw 291.

[0039] Assuming the initial compression of the third spring 279 in resistance assembly 269 is X0 for each gear, the rotation angle of the first variable diameter wheel 282, the second variable diameter wheel 283, the third variable diameter wheel 284, or the fourth variable diameter wheel 285 is α, the radius of the first variable diameter wheel 282, the second variable diameter wheel 283, the third variable diameter wheel 284, or the fourth variable diameter wheel 285 is R2, and the radius of the third gear 274 is R1, then R2 = R1 + α * π * R1² / 180 * X0, thus ensuring that the motion resistance is a constant value during training at a certain intensity level.

[0040] The first training component 100 and the second training component 200 of this invention can be disassembled and folded for storage, allowing them to be placed in public places or used at home, thus expanding their application scenarios. When not in use, the invention can be stored away without taking up too much space, freeing up more activity space for people. This invention provides three training modes—shoulder training, waist training, and leg training—through the first training component 100 and the second training component 200. Furthermore, after being assembled together, the first training component 100 and the second training component 200 can utilize the resistance component 269 in the first training component 100 to perform rehabilitation training of different intensities on the shoulders, waist, or legs as needed. This overcomes the shortcomings of traditional training equipment with its single function, facilitating multi-dimensional exercise rehabilitation training on the same equipment and greatly improving the efficiency of rehabilitation training. The resistance component 269 in the second training component 200 of this invention provides four levels of training intensity to the rehabilitation trainee simply by adjusting the compression of a third spring 279. The preset compression and corresponding elasticity changes of the third spring 279 at each level are matched with the diameter variation patterns of the first variable-diameter wheel 282, the second variable-diameter wheel 283, the third variable-diameter wheel 284, and the fourth variable-diameter wheel 285, ensuring that the resistance output of the resistance component 269 maintains a constant value at each level. This ensures that the trainee receives a constant intensity training at each level, preventing the user from unconsciously using inertia or body swaying to "borrow" force to complete movements due to non-standard movement patterns. This is beneficial for the target muscle groups and joints to exert force, avoiding injuries caused by abnormal joint stress. Compared to the traditional method of providing training intensity through weights, the resistance component 269 is smaller and lighter, and more convenient, effectively overcoming the disadvantages of using weights to provide training intensity. The present invention effectively overcomes the problem of mismatch between the extension distance of the fourth pull rope 262 and the extension distance of the third spring 279 in the resistance component 269 by means of the transmission structure 225 set on the crossbeam 202 of the second training component 200. This makes the third spring 279 have a smaller compression distance when the fourth pull rope 262 has a large pull distance, which helps to reduce the overall volume of the second training component 200 and makes it easier for the second training component 200 to occupy less space after being folded and stored.

[0041] The operation flow of this invention is as follows: In the initial state, the first training component 100 and the second training component 200 are in the assembled and connected unfolded state. The first locking lugs 133 on the two sockets 132 and the second locking lugs 219 on the corresponding vertical rods 203 are connected and locked by the locking rods 134. The second locking sleeves 207 on the insert rods 205 are fitted onto the corresponding second guide sleeves 122 to lock the corresponding second guide sleeves 122 and the insert rods 205. The insert block 210 on the second slide post 209 is inserted into the second slot 128 on the corresponding first slide post 127. The insert plate 206 at the end of the insert rod 205 is inserted into the first slot 123 at the end of the corresponding second guide sleeve 122. The two slide blocks 221 are both located at their lowest height and abut against the corresponding fourth limiting block 220. The two slide sleeves 214 are both located at their lowest height. The two first locking sleeves 131 are both fitted onto the corresponding side rods 129 and support rods 130 to lock the open state of the support rods 130. Each resistance assembly 269 has four pull blocks 293 located within its corresponding connecting sleeve 216. The footrest 117 and backrest 115 are in the open position, while the side supports 107, rear support 106, and front support 104 are in the extended position. The four pull blocks 293 in the resistance assembly 269 abut against the upper side of the housing 270, and the portion of the fourth pull rope 262 connected to the corresponding pull block 293 is tangent to the minimum radius of the corresponding variable-diameter wheel. The top block 277 is located at the bottom of the energy storage sleeve 278 under the action of the third spring 279. The seat plate 114 in the first training assembly 100 is closest to the footrest 117 under the action of the first spring 111, and the two first rollers 121 abut against the first pull rope 126.

[0042] When training is required using this invention, first determine the resistance level of the resistance component 269 according to actual needs. Insert the pin 218 into the second socket 294 and the corresponding first socket 217 on the corresponding pull block 293. Rotate the adjusting bolt 281 to move the top block 277 by a certain amplitude, so that the pointer 295 points to the scale of the corresponding level. Rotate the locking screw 291 on the corresponding variable diameter wheel of the corresponding level with a screwdriver to insert it into the corresponding third slot 273 on the tenth rotating shaft 272 to lock the corresponding variable diameter wheel with the tenth rotating shaft 272. The other variable diameter wheels will not rotate synchronously with the tenth rotating shaft 272 and will be in the initial state where the fifth pull rope 292 is tangent to its minimum radius under the action of the corresponding fourth spring 288. The strength resistance provided by the first variable diameter wheel 282, the second variable diameter wheel 283, the third variable diameter wheel 284 and the fourth variable diameter wheel 285 increases sequentially, and the initial compression of the corresponding level of the third spring 279 of the four gradually increases.

[0043] When shoulder joint training is required, sit on the seat 114 with your back against the backrest 115, raise your hands and firmly grasp the two pull rings 263, and simultaneously swing forward to pull the two fourth pull ropes 262. The limiting structure 264 that works with the fourth pull ropes 262 ensures that the fourth pull ropes 262 will not detach from the second winding wheel 261 when swinging forward and provides minimal resistance. The two fourth pull ropes 262 drive the corresponding second winding wheel 261 to rotate, releasing the fourth pull ropes 262. Both second winding wheels 261 drive the corresponding first winding wheel 227 to decelerate and rotate through the corresponding transmission structure 225, winding the third pull rope 223 and pulling the corresponding... The slide block 221 moves upward. Both slide blocks 221 drive the corresponding sliding sleeve 214 to move upward slowly through the corresponding movable pulley 213 and the third pull rope 223. The sliding sleeve 214 drives the corresponding variable diameter wheel to rotate with a slowly increasing diameter through the connecting sleeve 216, the pin 218, the corresponding pull block 293 and the fifth pull rope 292. The variable diameter wheel drives the top block 277 to compress the third spring 279 through the tenth rotating shaft 272, the third gear 274, the rack 275 and the top rod 276. The compression of the third spring 279 provides the fourth pull rope 262 with tensile resistance to achieve the corresponding intensity of shoulder forward swing training.

[0044] When both arms are swung upwards from the front, the fourth pull rope 262 is wound back under the reset action of the fourth spring 288 and the third spring 279 in the corresponding variable diameter wheel. After the two fourth pull ropes 262 have finished winding back, both arms are raised. Then, the arms are swung downwards to the sides to pull the two fourth pull ropes 262 for training. The limiting structure 264 allows the fourth pull ropes 262 to change direction and stretch without detaching from the second winding wheel 261. At this time, the operation of the second training component 200 is exactly the same as described above.

[0045] When leg joint training is required, retract your hands and place your feet on the footrest 117 to perform leg extension and flexion exercises. When the legs extend, the buttocks will cause the seat 114 to move backward. The seat 114 pulls the first pull rope 126 backward through the first rollers 121 at the ends of the two swing arms 120 of the rotating column 113. The first pull rope 126 pulls the two first sliding columns 127. The two first sliding columns 127 drive the corresponding variable diameter wheel of the corresponding gear through the corresponding second sliding column 209, second pull rope 211, sliding sleeve 214, connecting sleeve 216 and corresponding stop pull block 293, which in turn drives the third spring 279 to compress. The compression of the third spring 279 provides a constant strength resistance for leg extension training. When the legs contract and bend, the seat 114 returns to its original position under the combined action of the first spring 111, first pull rope 126, second spring 125, third spring 279 and fourth spring 288.

[0046] When waist training is required, grip the two handles 119 with both hands and twist your waist to make the seat 114 swing back and forth. The seat 114 alternately pushes the first pull rope 126 backward through the first rollers 121 at the ends of the two swing arms 120 on the rotating column 113. The first pull rope 126 provides the corresponding training intensity resistance through the extension and contraction of the third spring 279 on one side of the transmission, ensuring effective training.

[0047] When not using this invention, remove the locking rod 134, slide the first locking sleeve 131 onto the corresponding support rod 130 to disengage from the corresponding side rod 129, slide the second locking sleeve 207 onto the corresponding insertion rod 205 and disengage from the corresponding second guide sleeve 122, and then remove the second training component 200 upward from the socket 132 of the first training component 100. During the disengagement process, the insertion block 210 on the second sliding post 209 disengages from the second slot 128 on the first sliding post 127.

[0048] After separating the first training component 100 and the second training component 200, the two crossbars of the second training component 200 are folded by swinging them toward each other relative to the connecting rod 201. Then, the front support 104, rear support 106, two side supports 107, foot pedal, backrest 115 and two support rods 130 of the first training component 100 are folded.

[0049] The first training component 100 in this invention can be purchased and used separately by replacing the first spring 111 and the second spring 125 with different elastic coefficients at the factory, thus saving costs. In this case, the first training component 100 provides a certain range of intensity for the waist and leg training of the rehabilitation trainee through the extension and contraction of the first spring 111 and the second spring 125, respectively. When the first training component 100 is used in conjunction with the second training component 200, the elastic coefficients of the first spring 111 and the second spring 125 are very small, and they are only used to reset the first sliding column 127 and the seat plate 114, respectively. At this time, the elastic force changes of the first spring 111 and the second spring 125 during the extension and contraction process have little impact on the waist and leg joints, and the intensity resistance required for waist and leg training is mainly provided precisely by the resistance component 269 in the second training component 200.
