Description

Technical Field

[0001] The present invention relates to the technical field of exercise equipment, and in particular to an exercise auxiliary device for obese patients. Background Art

[0002] For obese patients, proper exercise is an important way to lose weight and improve health. However, due to their excessive weight, obese patients often face many difficulties in the exercise process. On the one hand, they may find it difficult to find an exercise method that suits them, because traditional exercise methods may put too much strain on their bodies. On the other hand, obese patients are also more likely to get injured during exercise, so they need safer and more effective exercise assistive devices to help them exercise.

[0003] The exercise assisting devices in the prior art often exercise obese patients by performing strength training on the user's upper and lower limbs. However, in the process of performing strength training on obese patients, the exercise assisting devices in the prior art often lack a limit on the amount of operation, resulting in a heavy exercise burden on obese patients and poor training effect.

[0004] In summary, how to solve the problem that the existing exercise assisting device often lacks the limitation of the running amount during the strength training of obese patients, resulting in a heavy exercise burden on obese patients and poor training effect has become a difficult problem that needs to be solved in the current field. Therefore, it is necessary to propose a more reasonable exercise assisting device for obese patients. Summary of the invention

[0005] In order to solve the above problems, the present invention provides an exercise assisting device for obese patients. The design of the foot pedals and gears can perform strength training on the patient's lower limbs, the design of the T-shaped frame and the top rod can transmit the force, and the design of the push-pull rod and the armrest frame can realize strength training on the patient's upper limbs; at the same time, the design of the limit rod and the slide rail will limit the movement range of the push-pull rod, thereby reducing the exercise burden of obese patients and improving the exercise effect.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: an exercise auxiliary device for obese patients, comprising a base and a seat fixedly connected to the top of the base, a training box also fixedly connected to the top of the base, a push-pull rod slidingly fitted inside the training box, and an end of the push-pull rod away from the training box is fixedly connected to an armrest frame; a T-shaped frame and a limit rod are fixedly connected to the side wall of the push-pull rod; a gear and a cam are rotatably fitted to the inner side wall of the training box, and a push rod for pushing the T-shaped frame and the cam is symmetrically fixedly connected to the side wall of the gear; a slide rail is fixedly connected to the side wall of the cam, and the limit rod is located in the slide rail and slidably fitted therewith; a center rod is coaxially fixedly connected to the gear, both ends of the center rod pass through the side wall of the training box and rotatably fit therewith, and both ends of the center rod are hinged with foot pedals.

[0007] The training box is also provided with a limiting component for limiting the user's exercise amount and an adjusting component for adjusting the movement resistance of the push-pull rod.

[0008] The technical principles of the above scheme are as follows:

[0009] The user places his feet on the foot pedal and uses his feet to rotate the foot pedal to perform strength training for the lower limbs; at the same time, the foot pedal will drive the center rod and the gear to rotate, and the gear will drive the push rod to rotate; the push rod will continuously push the T-shaped frame and the cam to move; when the push rod pushes the T-shaped frame to move, the T-shaped frame will pull the armrest to move, and then drive the user's upper limbs to move to one side; when the push rod pushes the cam to rotate counterclockwise, the cam will drive the slide rail to rotate counterclockwise, and the slide rail will move the limit rod, and then drive the push-pull rod and the armrest to move, and drive the user's upper limbs to move to the other side, thereby realizing training of the patient's upper limbs; due to the limiting effect of the slide rail on the limit rod, the movement stroke of the push-pull rod is relatively moderate, avoiding excessive exercise burden on obese patients.

[0010] In this process, the total amount of the user's movement can be adjusted by limiting the component, and the movement resistance of the push-pull rod can be adjusted by adjusting the component, thereby adjusting the difficulty of the user's movement.

[0011] The above scheme has the following beneficial effects:

[0012] 1. The exercise assisting devices in the prior art, due to the lack of limitation on the movement, rely solely on the user to control the movement range during the training process. Obese patients are often more likely to feel tired and uncomfortable during physical exercise due to their large weight. If the movement range is too large, it will not only increase the difficulty of the patient's exercise, but may also cause unnecessary physical injuries. The present invention can effectively limit the movement range through the design of the limit rod and the slide rail. During the training process, due to the limiting effect of the slide rail on the limit rod, the movement range of the push-pull rod is effectively controlled within a moderate range. While ensuring the training effect, it can also ensure that the patient will not bear excessive physical burden during the training process due to excessive movement.

[0013] 2. The present invention transmits the power generated by the lower limbs to the upper limbs through the rotation of the foot pedal driving gear, and then through the design of the push rod, T-shaped frame, cam, slide rail and limit rod, thereby realizing simultaneous training of the patient's lower limbs and upper limbs. This comprehensive training mode helps to improve the patient's overall physical fitness. While enhancing the patient's upper and lower limb muscle strength and endurance, it can also train the patient's limb coordination ability, thereby improving the training effect.

[0014] 3. The present invention adjusts the total amount of exercise according to the patient's physical condition and training needs through the design of limiting components and adjusting components, and through the overall control of the exercise process, it ensures that the training is effective while not causing excessive fatigue to the user; the adjusting component can adjust the difficulty of each force exerted by the user according to the patient's physical condition and training needs, and then adjust the training difficulty. The combination of the two makes each exercise more friendly and reasonable to obese patients.

[0015] Furthermore, the limiting component includes a controller and a toothed plate meshing with the gear, the toothed plate slidingly cooperates with the training box; the toothed plate is fixedly connected to an output plate at one end away from the training box, the top of the base at one end away from the training box is fixedly connected to a support plate, the side wall of the support plate is fixedly connected to a telescopic rod, and the output shaft of the telescopic rod is fixedly connected to a baffle for hindering the movement of the output plate; the controller is used to control the operation of the telescopic rod, and thereby adjust the position of the baffle.

[0016] Beneficial effect: When the foot pedal rotates clockwise, the foot pedal will drive the gear to rotate clockwise. Since the tooth plate is meshed with the gear, the gear will drive the tooth plate to push the output plate to move toward the baffle. When the output plate contacts the baffle, the tooth plate cannot continue to move toward the baffle, and the gear and foot pedal cannot rotate clockwise, thereby reminding the user that the total amount of exercise has been reached. Pushing the output plate back into the training box can set a new total amount of exercise. The user can adjust the output distance of the telescopic rod through the controller to adjust the position of the baffle, and then adjust the movable distance of the output plate to set different total amounts of exercise.

[0017] Furthermore, the adjustment component includes a piston plate, which is fixedly connected to one end of the push-pull rod away from the armrest; a piston chamber for the piston plate to slide is opened in the training box, and the side wall of the piston chamber is fixedly connected to an intake check valve and an exhaust check valve; the controller is used to control the operation of the intake check valve and the exhaust check valve, thereby adjusting the air pressure in the piston chamber.

[0018] Beneficial effects: when the push-pull rod slides back and forth in the training box, the piston plate also slides back and forth in the piston cavity. In the initial state, the intake check valve and the exhaust check valve remain closed, and there is a certain amount of gas in the piston cavity, and thus a certain amount of pressure; when the user pulls the push-pull rod to the left, a negative pressure will be generated on the right side of the piston plate, so that the user needs more force to pull the push-pull rod; when the user pushes the push-pull rod to the right, due to the certain air pressure on the right side of the piston plate, the user needs more force to push the push-pull rod, thereby producing a training effect; by controlling the intake check valve to intake air through the controller, the air pressure in the piston cavity will increase, thereby increasing the training resistance; by controlling the exhaust check valve to exhaust air through the controller, the air pressure in the piston cavity will decrease, thereby reducing the training resistance.

[0019] Furthermore, a plurality of rollers for limiting the push-pull rods are rotatably connected in the training box.

[0020] Beneficial effects: The roller can limit the push-pull rod and reduce the shaking of the push-pull rod during movement. At the same time, the roller can reduce the friction between the push-pull rod and the training box during movement, making the push-pull rod move more smoothly and increasing the service life of the training box and the push-pull rod.

[0021] Furthermore, a display for displaying the user's exercise duration and motion images is fixedly connected to one end of the slide rail away from the cam, and a controller is used to control the operation of the display; a moving slot for the display to move is opened on the top of the training box.

[0022] Beneficial effects: The display can show the user's exercise duration and exercise images, which is convenient for the user to understand his or her own exercise status. At the same time, when the slide rail rotates, it will also drive the display to rotate together. When the user pulls the push-pull rod to the left, the slide rail and the display will rotate to the left. When the user pulls the push-pull rod to the right, the slide rail and the display will rotate to the right, so that the display can be kept as parallel as possible to the patient's body, so that the patient can better observe his or her own exercise status during exercise.

[0023] Furthermore, a speed sensor is fixedly connected to the gear, and the controller is used to receive the speed value monitored by the speed sensor, and control the operation of the intake check valve and the exhaust check valve based on the speed value.

[0024] Beneficial effects: When the user is exercising, the gears will rotate continuously, and the speed sensor will be used to monitor the speed of the gears, which can represent the user's exercise frequency. When the user just starts exercising, his physical condition is better, and the speed value at this time represents the user's exercise frequency under normal circumstances. When the speed value decays by a certain proportion, the controller will open the exhaust one-way valve to reduce the gas in the piston chamber, thereby reducing the air pressure in the piston chamber, thereby reducing the difficulty of training and avoiding excessive exercise burden on obese patients.

[0025] Furthermore, one end of the tooth plate away from the output plate is fixedly connected to a limit plate, and the limit plate is slidably matched with the bottom wall of the training box.

[0026] Beneficial effect: The design of the limit plate can prevent the tooth plate from slipping and deflecting from the training box, thereby improving the running stability of the tooth plate.

[0027] Furthermore, a weight scale is fixedly connected to the seat, and the controller is used to receive the weight value monitored by the weight scale and control the operation of the telescopic rod, the air intake check valve and the exhaust check valve based on the weight value.

[0028] Beneficial effects: When the user sits on the chair, the scale will detect the patient's weight, and the controller will adjust the output distance of the telescopic rod according to the user's weight to adjust the total amount of exercise, while controlling the operation of the intake check valve and the exhaust check valve to adjust the difficulty of the exercise.

[0029] Furthermore, a sponge cover is fixedly connected to the handrail frame.

[0030] Beneficial effect: The sponge cover can increase the comfort of the user's hands and improve the comfort of exercise.

[0031] Furthermore, an anti-skid layer is fixedly connected to the foot pedals.

[0032] Beneficial effect: The anti-skid layer can increase the friction between the sole of the user's foot and the anti-skid layer, allowing the user to exercise better.

[0033] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The following is further described in detail through specific implementation methods:

[0039] Embodiment 1:

[0040] As attached Figure 1-3 As shown: an exercise auxiliary device for obese patients, comprising a base 1 and a seat 2 fixedly connected to the top of the base 1 by bolts, a training box 3 is also fixedly connected to the top of the base 1 by bolts, a push-pull rod 4 is slidably fitted inside the training box 3, and a handrail frame 9 is fixedly connected to the left end of the push-pull rod 4 by bolts; a T-shaped frame 5 and a limit rod 18 are fixedly connected to the side wall of the push-pull rod 4 by bolts; a gear 6 and a cam 10 are rotatably fitted to the inner side wall of the training box 3, and a top rod 7 for pushing the T-shaped frame 5 and the cam 10 is symmetrically fixedly connected to the side wall of the gear 6 by bolts; a slide rail 17 is fixedly connected to the side wall of the cam 10 by bolts, and the limit rod 18 is located in the slide rail 17 and slidably fits therewith; a center rod 8 is coaxially fixedly connected to the gear 6 with bolts, both ends of the center rod 8 pass through the side wall of the training box 3 and rotatably fit therewith, and both ends of the center rod 8 are hinged with foot pedals 20.

[0041] The training box 3 is also provided with a limiting component for limiting the user's exercise amount and an adjusting component for adjusting the movement resistance of the push-pull rod 4.

[0042] The limiting component includes a controller and a toothed plate 11 meshing with the gear 6, and the toothed plate 11 is slidably matched with the training box 3; the left end of the toothed plate 11 is bolted fixedly connected to the output plate 12, the top left end of the base 1 is bolted fixedly connected to the support plate 21, the side wall of the support plate 21 is fixedly connected to the telescopic rod 22, and the output shaft of the telescopic rod 22 is bolted fixedly connected to the baffle 23 used to hinder the movement of the output plate 12; the controller is used to control the operation of the telescopic rod 22, and then adjust the position of the baffle 23.

[0043] The adjusting assembly includes a piston plate 13, which is fixedly connected to the right end of the push-pull rod 4 with bolts; a piston cavity for the piston plate 13 to slide is opened in the training box 3, and the side walls of the piston cavity are fixedly connected with an intake check valve 14 and an exhaust check valve 15 by bolts; the controller is used to control the operation of the intake check valve 14 and the exhaust check valve 15, thereby adjusting the air pressure in the piston cavity.

[0044] A speed sensor is screw-fixedly connected to the gear 6 , and the controller is used to receive the speed value monitored by the speed sensor, and control the operation of the intake check valve 14 and the exhaust check valve 15 based on the speed value.

[0045] The specific implementation process is as follows:

[0046] by Figure 1 and Figure 2 For example, before the start of exercise, the user can adjust the output distance of the telescopic rod 22 through the controller according to his own situation, so as to adjust the position of the baffle 23, and then adjust the movable distance of the output plate 12, so as to set the total amount of exercise for this exercise; then open the air intake check valve 14 through the controller, keep the exhaust check valve 15 closed, and input a certain amount of gas into the piston chamber, so that there is a certain pressure in the piston chamber to serve as the resistance of the user during this exercise; when the user pulls the push-pull rod 4 to the left, negative pressure will be generated on the right side of the piston plate 13, so that the user needs more force to pull the push-pull rod 4; when the user pushes the push-pull rod 4 to the right, due to the presence of a certain air pressure on the right side of the piston plate 13, the user needs more force to push the push-pull rod 4, thereby training the user's upper limb strength.

[0047] After the pressure adjustment is completed, the user sits on the seat 2, holds the armrest 9, places the feet on the foot pedal 20, and uses the foot to rotate the foot pedal 20 clockwise, so as to perform strength training for the lower limbs; at the same time, the foot pedal 20 will drive the center rod 8 and the gear 6 to rotate clockwise, and the gear 6 will drive the push rod 7 to rotate clockwise; the push rod 7 will continuously push the T-shaped frame 5 and the cam 10 to move; when the push rod 7 pushes the T-shaped frame 5 to move to the right, the T-shaped frame 5 will pull the armrest 9 to move to the right, thereby driving the user's upper limbs to move to the right; After one push rod 7 is separated from the T-shaped frame 5, the other push rod 7 will immediately push the cam 10 to rotate counterclockwise, and the cam 10 will drive the slide rail 17 to rotate counterclockwise, and the slide rail 17 will cause the limit rod 18 to move to the left, thereby driving the push-pull rod 4 and the armrest frame 9 to move to the left, and driving the user's upper limbs to move to the left, so as to achieve training of the patient's upper limbs; and in this process, due to the limiting effect of the slide rail 17 on the limit rod 18, the movement stroke of the push-pull rod 4 is relatively moderate, thereby effectively avoiding excessive exercise burden on obese patients. The limit rod 18 will also limit the slide rail 17. When the push-pull rod 4 moves to the right, the limit rod 18 will drive the slide rail 17 and the cam 10 to swing to the right and reset, thereby swinging back and forth.

[0048] During this process, when the foot pedal 20 rotates clockwise, the foot pedal 20 will drive the gear 6 to rotate clockwise. Since the toothed plate 11 is meshed with the gear 6, the gear 6 will drive the toothed plate 11 to push the output plate 12 to move toward the baffle 23. When the output plate 12 contacts the baffle 23, the toothed plate 11 cannot continue to move toward the baffle 23, and the gear 6 and the foot pedal 20 cannot rotate clockwise either, thereby reminding the user that the total amount of exercise has been reached and appropriate adjustments can be made. The user can also judge the current amount of exercise based on the output distance of the output plate 12. For example, if the output plate 12 is still half the distance from the baffle 23, the current amount of exercise is about 50% of the total amount of exercise, which has not yet reached the total amount of exercise and needs to continue exercising, so that the user can understand his or her own exercise situation more clearly and improve the controllability of the exercise.

[0049] When the user is exercising, the controller can control the intake check valve 14 to intake air, increase the air pressure in the piston chamber, and thus increase the training resistance; the controller can also control the exhaust check valve 15 to exhaust air, reduce the air pressure in the piston chamber, and thus reduce the training resistance. During the user's exercise, the gear 6 will rotate continuously, and the speed sensor monitors the speed value of the gear 6, which can represent the user's exercise frequency; when the user just starts to exercise, the physical condition is good, and the speed value at this time represents the user's exercise frequency under normal circumstances. When the speed value is reduced to a certain value, the controller will open the exhaust check valve 15 to reduce the gas in the piston chamber, thereby reducing the air pressure in the piston chamber, and then reduce the training difficulty; the more the speed value is reduced, the lower the training difficulty, so as to achieve adaptive adjustment of the training difficulty and avoid excessive exercise burden on obese patients.

[0050] After the exercise is finished, the user can push the output plate 12 back into the training box 3, so that it is convenient to set a new total amount of exercise and perform a new exercise next time.

[0051] The exercise assisting device in the prior art lacks the limitation on the movement, and the movement range is controlled by the user alone during the training process. Obese patients are often more likely to feel tired and uncomfortable during physical exercise due to their large weight. If the movement range is too large, it will not only increase the difficulty of the patient's exercise, but may also cause unnecessary physical injuries. This embodiment can effectively limit the movement range through the design of the limit rod 18 and the slide rail 17, and can effectively set the total amount of exercise through the design of the output plate 12 and the baffle 23; during the training process, while ensuring the training effect, it can also ensure that the patient will not bear too much physical burden due to excessive movement during the training process.

[0052] The gear 6 is driven by the rotation of the foot pedal 20, and then the power generated by the lower limbs is transmitted to the upper limbs through the design of the top rod 7, T-shaped frame 5, cam 10, slide rail 17 and limit rod 18, thereby realizing simultaneous training of the patient's lower limbs and upper limbs. This comprehensive training mode helps to improve the patient's overall physical fitness. While enhancing the patient's upper and lower limb muscle strength and endurance, it can also train the patient's limb coordination ability, thereby improving the training effect.

[0053] Embodiment 2:

[0054] As attached Figure 2 As shown, different from the above-mentioned embodiment, a plurality of rollers 16 for limiting the push-pull rod 4 are rotatably connected in the training box 3 .

[0055] The specific implementation process is as follows: during the exercise, the roller 16 can limit the push-pull rod 4 to reduce the shaking of the push-pull rod 4 during the movement. At the same time, the roller 16 can reduce the friction between the push-pull rod 4 and the training box 3 during the movement, making the push-pull rod 4 move more smoothly and improving the service life of the training box 3 and the push-pull rod 4.

[0056] Embodiment 3:

[0057] As attached Figure 1 As shown, different from the above-mentioned embodiment, the end of the slide rail 17 away from the cam 10 is bolted and fixedly connected with a display 24 for displaying the user's exercise duration and motion images, and the controller is used to control the operation of the display 24; a movable slot for the display 24 to move is opened on the top of the training box 3.

[0058] The specific implementation process is as follows: during exercise, the display 24 can display the user's exercise duration and exercise images, which is convenient for the user to understand his or her own exercise status. At the same time, when the slide rail 17 rotates, it will also drive the display 24 to rotate together. When the user pulls the push-pull rod 4 to the left, the slide rail 17 and the display 24 will rotate to the left. When the user pulls the push-pull rod 4 to the right, the slide rail 17 and the display 24 will rotate to the right, so that the display 24 can be kept as parallel as possible to the patient's body, so that the patient can better observe his or her own exercise status during exercise.

[0059] Embodiment 4:

[0060] As attached Figure 2 As shown, what is different from the above-mentioned embodiment is that a limiting plate 19 is welded to the right end of the tooth plate 11 , and the limiting plate 19 is slidably matched with the inner bottom wall of the training box 3 .

[0061] The specific implementation process is as follows: the design of the limiting plate 19 can prevent the tooth plate 11 from slipping out and deflecting from the training box 3, thereby improving the operating stability of the tooth plate 11.

[0062] Embodiment 5:

[0063] As attached Figure 1 As shown, different from the above-mentioned embodiment, a weight scale (not shown in the figure) is embedded in the seat 2, and the controller is used to receive the weight value monitored by the weight scale, and control the operation of the telescopic rod 22, the air intake check valve 14 and the exhaust check valve 15 based on the weight value.

[0064] The specific implementation process is as follows: when the user sits on the seat 2, the weight scale will detect the patient's weight, and the controller will adjust the output distance of the telescopic rod 22 according to the user's weight to adjust the total amount of exercise, and at the same time control the operation of the air intake check valve 14 and the exhaust check valve 15 to adjust the difficulty of the exercise. The heavier the user's weight, the greater the user's exercise burden. The controller will increase the output distance of the telescopic rod 22, reduce the total amount of exercise, close the air intake check valve 14, open the exhaust check valve 15, reduce the air pressure in the piston chamber, and reduce the difficulty of exercise, thereby reducing the burden on the body while achieving the exercise effect.

[0065] Embodiment 6:

[0066] As attached Figure 1 As shown, what is different from the above-mentioned embodiment is that a sponge cover is fixedly bonded to the handrail frame 9.

[0067] The specific implementation process is as follows: the sponge sleeve can increase the comfort of the user's hands and improve the comfort of exercise.

[0068] Embodiment 7:

[0069] As attached Figure 1 As shown, different from the above-mentioned embodiment, an anti-slip layer is fixedly bonded on the foot pedal 20 .

[0070] The specific implementation process is as follows: the anti-slip layer can increase the friction between the user's sole and the anti-slip layer, allowing the user to exercise better.

[0071] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
