Description

Joint exercise device for home

The present invention relates to a home joint exercise apparatus, and more particularly, to a home joint exercise apparatus capable of performing joint movement by using a pedal driven by a motor or by rotating a pedal directly by a user.

With the increase of the elderly population and the spread of leisure sports, surgeries for knee joint function impairment are increasing. If the joint is left untreated after knee joint-related procedures such as artificial joint surgery to repair damage, cruciate ligament reconstruction, and meniscus treatment, the joint function will gradually be lost. In order to prevent such joint contracture, joint rehabilitation exercise must be performed within 3 to 4 days after surgery.

However, since the joint exercise device for joint rehabilitation is large and expensive, it is only provided in hospitals specializing in rehabilitation treatment, and it is difficult to perform joint exercise at home because small and inexpensive home joint exercise equipment is not supplied.

Therefore, some elderly or surgical patients are performing joint exercises instead of the joint exercise device with an indoor bicycle exercise device. However, in the case of the elderly or surgical patients, it is difficult to maintain a posture while sitting on a bicycle or exercise by applying force on their own because muscle strength is insufficient and joint function is weakened. Since it is difficult to perform joint movement by patient's own strength accompanied by pain, an indoor bicycle exercise device that needs to perform movement depending on patient's magnetism is not suitable as a joint exercise device for the elderly or a joint rehabilitation exercise device for a surgical patient.

1 is a view showing a schematic appearance of a home joint exercise device according to an embodiment of the present invention, Figure 2 is a view showing an exploded state of the home joint exercise device according to an embodiment of the present invention. And FIG. 3 is a diagram conceptually illustrating a pedal unit according to an embodiment of the present invention.

The joint exercise device according to the present embodiment is an exercise device that allows the user's ankle and knee joints to be exercised in the process of rotating the pedal like a bicycle after the user's foot is mounted on the pedal.

Referring to FIG. 1 , for this purpose, the joint exercise device may be configured to include a body part 10 , a pedal part 30 , and a support housing 50 .

More specifically, the pedal unit 30 includes a pair of pedals 31 coupled to both sides of the body unit 10 , and after the user puts their feet on the pedals 31 , the pedals 31 are operated like a bicycle. By rotating it, you can exercise your ankle and knee joints. The support housing 50 is disposed on the lower side of the main body 10 to support the main body 10 so that the main body 10 maintains an erected state from the ground, and prevents the user from moving or tilting the joint exercise device during pedal exercise. This allows the user to exercise stably.

Here, the joint exercise device according to the present embodiment is not provided with a separate saddle unlike the bicycle. Therefore, in the joint exercise device according to this embodiment, the user can exercise while standing on the pedal 31, but preferably, while sitting or lying on the floor, the user places his or her feet on the pedal 31 for joint movement in a comfortable posture. can be performed.

The joint exercise device according to the present embodiment includes a manual mode in which the user rotates the pedal 31 by a user's own force for joint movement, and the pedal 31 rotates by a motor to enable joint movement without the user applying a separate force. You can select and drive one of the automatic modes. The user may select one of the manual mode and the automatic mode through the input/output unit 11 provided in the body unit 10 .

Accordingly, the user may select any one of the manual mode and the automatic mode to perform joint exercise according to his/her muscle or joint state. Specifically, if the user's muscle or joint is in a relatively recovered state, he/she may select a manual mode to rotate the pedal 31 by magnetic force and perform joint motion. On the other hand, a user who is determined to be in a weakened state of his or her muscles or joints may select an automatic mode and place the feet on the pedal 31 rotated by a motor to perform joint motion.

In order to enable joint movement through such an automatic mode, the pedal unit 30 according to the present embodiment includes a motor 32 and a pair of rotating disks 33 to automatically rotate the pedal 31 during automatic mode. ) may be included.

2, the motor 32 is built into the main body 10, and the rotating disk 33 is coupled to the motor 32 on both sides of the main body 10 to be connected to the motor 32. rotated by At this time, the rotation disk 33 has a guide protrusion 331 spaced apart from the center is formed, and the pedal 31 has a coupling hole 311 through which the guide protrusion 331 is rotatably inserted and coupled. When the guide protrusion 331 is inserted and fastened into the coupling hole 311 , when the rotation disk 33 is rotated by the motor 32 , the pedal 31 can rotate in a circle in the circumferential direction of the rotation disk 33 . have. In this case, the user may select the rotation speed of the pedal 31 step by step through the input/output unit 11 , and the rotation speed of the motor 32 may be controlled according to the selected step.

Preferably, the pedal 31 may be provided with a coupling hole 311 on one side of the front end and a wheel 312 on the lower side of the rear end. Therefore, when the motor 32 is driven, the front end of the pedal 31 rotates in a circle along the circumferential direction of the rotating disk 33 , and the rear end of the pedal 31 reciprocates in the front-rear direction. Accordingly, during exercise, the user's ankle joint is not fixed, but bends and stretches, and it can be a natural ankle joint movement. At this time, as shown in FIG. 2 , when the pedal 31 rotates, a guide groove 51 into which a lower portion of the wheel 312 is inserted into the upper surface of the support housing 50 to guide the reciprocating path of the wheel 312 . ) can be formed. The guide groove 51 is formed so that the wheel 312 does not deviate from a predetermined path during reciprocating motion.

The joint exercise device according to the present embodiment is provided with a manual mode so that a user whose muscle or joint state has relatively recovered may perform an exercise while rotating the pedal 31 with his/her own power, but the user's muscles or joints performing joint motion in the manual mode Since the state is also weaker than that of the general public, even in the manual mode, the pedal 31 should be rotated with a small force.

To this end, the guide protrusion 331 of the pair of rotating disks 33 may be fixedly coupled to the drive shaft of the motor 32 so as to be spaced apart from each other in opposite directions from the center of the rotating disk 33 . Therefore, the pedals 31 on both sides are fixedly coupled to the drive shaft of the motor 32 so as to be spaced apart from each other in opposite directions from the center of the rotation disk 33 . Assuming that the user rotates the pedal 31 clockwise, a relatively small force is required to rotate the pedal 31 arranged at 12 o'clock to 6 o'clock, but the pedal 31 arranged at 6 o'clock Relatively large force is required to rotate to the 12 o'clock position. However, as described above, when the pedals 31 on both sides are fixedly coupled to the drive shaft of the motor 32 so as to be spaced apart from each other in opposite directions from the center of the rotation disk 33, one side of the pedal 31 is positioned in the 6 o'clock direction. The pedal 31 on the other side is positioned at 12 o'clock. Therefore, when the pedal 31 on one side located at the 6 o'clock position is positioned in the 12 o'clock direction, a small force is applied to the pedal 31 on the other side located in the 12 o'clock direction without applying force to the pedal 31 on the one side to 6 o'clock. In the process of positioning in the direction, the pedal 31 on one side is positioned at 12 o'clock. Accordingly, the user may alternately apply force to the pedals 31 on both sides through both feet so that the pedals 31 on both sides rotate in a circle even if a small force is applied.

4 is a view showing a side cross-section of the guide groove according to an embodiment of the present invention, Figure 5 is a graph showing the kinetic energy of the wheel according to the position of the guide groove according to an embodiment of the present invention.

As described above, the joint exercise device according to the present embodiment should allow the user to rotate the pedal 31 with a small force even in the manual mode.

Referring to FIG. 4 , for this purpose, the guide groove 51 may be formed to have a different depth according to a reciprocating path. Specifically, at least some sections of the entire section of the guide groove 51 form a downhill slope that gradually increases in depth along the longitudinal direction. As shown in FIG. 5 , the downhill slope can accelerate the rotation of the pedal 31 by changing the potential energy along the reciprocating path of the wheel 312 . That is, when the wheel 312 of the pedal passes the downhill slope, the rotation of the pedal 31 is accelerated so that the user can rotate the pedal 31 with less force. Accordingly, since the pedal 31 can maintain rotational motion even with less force, the user can perform joint motion even with a weak force, and also rhythmic joint motion by acceleration may be possible.

Here, even if the entire section of the guide groove 51 forms a downhill slope in one direction, the wheel 312 reciprocates along the guide groove 51. When the wheel 312 passes an uphill slope, since acceleration occurs in the process of passing the downhill slope, the wheel 312 can naturally pass through the uphill slope without applying a large force.

At this time, the guide groove 51 is formed to gradually deepen from one end toward the center along the longitudinal direction and gradually become shallower toward the other end through the center, so that the longitudinal section of the guide groove 51 forms one gentle trough. can In this case, since the wheel 312 reciprocates along the guide groove 51 when the pedal 31 rotates once, it passes through two downhill slope sections. Accordingly, the effect can be further improved than when the wheel 312 passes through one downhill slope section.

As described above, the effect may be improved as the number of times the wheel 312 passes through the downhill slope in the process of reciprocating along the guide groove 51 increases, but the number of downhill slope sections in the guide groove 51 of a predetermined length. If is excessively increased, the downhill slope section may become too short, making it difficult to generate sufficient acceleration. Therefore, preferably, the wheel 312 may pass through the number 4 downhill slope in the process of reciprocating along the guide groove 51 .

Specifically, as shown in FIG. 4 , the guide groove 51 according to this embodiment gradually deepens along the longitudinal direction from one end and becomes shallower again toward the center, gradually deepens along the longitudinal direction from the center and then again toward the other end. can be shallow. That is, the cross section of the guide groove 51 forms two valleys, and a ridge may be formed between the two valleys.

On the other hand, when the user rotates the pedal 31 in the manual mode or mounts the foot on the rotating pedal 31 in the automatic mode, if the contact state between the user's foot and the pedal 31 is not maintained, ankle or knee The joint may not be properly exercised.

To prevent this, the pedal 31 according to the present embodiment may be provided with an anti-separation strap (not shown) that is fastened to the user, the foot, and the ankle to prevent the user's foot from being separated from the pedal 31 during exercise.

Specifically, the detachment prevention strap is formed such that a part of the section is fixedly coupled to the pedal 31 and is fastened to wrap the user's foot and ankle through the remaining section, so that the close contact between the user's foot and the pedal 31 can be maintained. have. At this time, the detachment prevention strap is formed to be fastened while wrapping the user's foot and ankle, as well as being fastened to cover the calf above the ankle, thereby reducing the force applied to the user's ankle when the pedal 31 rotates. By dispersing it, it is possible to prevent excessive force from being applied to the ankle. In particular, in the manual mode, the user mainly rotates the pedal 31 by applying a force in the form of pushing the pedal 31 with the foot. can be rotated, so that it is possible to rotate the pedal 31 more easily and perform joint motion.

6 is a functional block diagram of a main body according to an embodiment of the present invention.

Referring to FIG. 6 , the main body 10 according to the present embodiment includes an input/output unit 11 , a mode selection unit 12 , a driving control unit 13 , a target speed determination unit 14 , a music playback unit 15 , and It may be configured to include a rotation speed sensing unit (16).

The input/output unit 11 allows the user to input an exercise stage (rotation speed stage of the motor), mode selection, exercise time, whether to play music, or the like, or output an exercise stage being performed, remaining exercise time, music being played, etc. . At this time, the modes selectable through the input/output unit 11 include an automatic mode in which the pedal 31 is automatically rotated by driving the motor 32 and a manual mode in which the pedal 31 is rotated by the user's power. The mode in which the mode selector 12 operates may be determined according to the mode selected in the unit 11 . The driving controller 13 may drive and control the motor 32 so that the pedal 31 automatically rotates when the automatic mode is determined by the mode selector 12 .

The music reproducing unit 15 may reproduce and output music so that the user can exercise with a pleasant and comfortable mind. In this case, the music reproducing unit 15 may notify the user through the music reproducing speed whether the user is exercising at an appropriate speed. Specifically, the rotation speed sensor 16 detects the rotation speed of the pedal 31 , and the music playback unit 15 plays the music according to the rotation speed of the pedal 31 detected by the rotation speed detection unit 16 . can be adjusted differently. Here, the rotational speed sensor 16 may directly sense the rotational speed of the pedal 31 , but indirectly sense the rotational speed of the pedal 31 by sensing the rotational speed of the motor 32 or the rotational disk 33 . You may. In addition, an encoder, a Hall sensor, or the like may be applied as the rotation speed sensing unit 16 .

Preferably, the music playback unit 15 may adjust the playback speed of music differently only in the manual mode. In the automatic mode, since the pedal 31 is rotated by the motor 32, the rotation speed is kept constant at the set speed, so there is no need to induce the user to rotate the pedal 31 at a constant speed through the playback speed of music. to be.

The target speed determination unit 14 may determine a target exercise speed of the pedal 31 suitable for the user. If the automatic mode is selected, the driving control unit 13 may drive and control the motor 32 to rotate according to the target movement speed determined by the target speed determination unit 14 .

The target speed determination unit 14 may determine the target speed based on the target speed directly input by the user through the input/output unit 11 or the exercise stage. For example, the user may directly select the target speed in any one of upper/middle/lower, or in more detail, may directly select the target speed in any one of the upper/middle/lower according to the age of the user.

Preferably, when the user inputs the user's age or surgery history and elapsed date through the input/output unit 11, the target speed may be automatically determined according to the inputted contents. For example, the target speed determining unit 14 may determine a slow speed as the target speed if the user's age is high, a major operation has been performed, or the elapsed date from the date of surgery is not long.

If the target speed is determined in the manual mode, the music playback unit 15 determines the music playback speed based on the determined target speed and plays music at the determined music playback speed. That is, when the rotational speed of the pedal 31 is within the critical range of the target speed, the music reproduction speed is determined as a constant speed to reproduce the music at the constant speed, and the rotational speed of the pedal 31 is out of the critical range of the target speed and is higher than the target speed. If it is fast, the music playback speed is determined to be a fast speed in proportion to the difference between the target speed and the rotation speed, and music is played quickly. The music can be played slowly by determining the music playback speed as a slow speed in proportion to the difference between the speed and the rotation speed. Accordingly, the user can enjoy the exercise with a pleasant and comfortable mind while listening to the music, and when exercising in the manual mode, the user can know the exercise speed suitable for the user through the music reproduction speed.
