Description

Exercise device capable of adjusting exercise load {EXERCISE DEVICE WITH ADJUSTABLE EXERCISE LOAD}

Embodiments relate to an exercise device, and more particularly, to an exercise device capable of adjusting an exercise load.

As interest in health has recently increased, interest in exercise devices capable of assisting users' health has increased. For example, an exercise device is a device that can perform a function of providing stimulation to a person's muscles in order to improve a person's muscle strength or muscle mass.

The exercise load means a force applied to the user's body by the exercise device for the user's exercise, and the exercise device needs to adjust the exercise load step by step according to the user.

If the exercise load is not properly adjusted, for example, when the load provided by the exercise device is small, the user may not be able to achieve a desired degree of improvement in muscle strength even if he or she exercises using the exercise device. Also, if the load provided by the exercise device is excessive, the user may be injured while exercising using the exercise device.

Hereinafter, the present disclosure will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating an exercise device according to an embodiment.

An exercise device 7 according to an embodiment may include a thigh wearing part 1, a lower leg wearing part 2, a rotation resistance part 3, a cable 4, and a central shaft member 5.

The thigh wearing portion 1 is a portion worn on the user's thigh when the user wears the exercise device 7 . Here, the femur refers to a portion of the user's body between the user's knee joint and the pelvis.

The first cover 11 may be detachably coupled to the thigh wearing portion 1 . For example, the first cover 11 may be disposed to cover the back of the thigh of the user. Here, the back side of the thigh may refer to one side of the thigh facing a direction parallel to the direction the user's buttocks are facing.

The lower leg wearing part 2 is a part worn on the user's lower leg when the user uses the exercise device 7 . Here, the lower leg refers to a portion of the user's body between the user's knee joint and ankle joint.

The lower thigh wearing portion 2 may be coupled to the thigh wearing portion 1 so as to be rotatable with respect to the thigh wearing portion 1 . When the user wears the exercise device 7, the user performs an exercise to rotate the wearable part 2 for the lower leg with respect to the wearable part 1 for the thigh, thereby performing an exercise for improving the user's lower extremity muscles.

The second cover 21 may be detachably coupled to the lower leg wearable part 2 . For example, the second cover 21 may be disposed to cover the front of the user's lower leg. Here, the front side of the lower leg may refer to one side of the lower leg parallel to the direction in which the lower leg of the user faces.

The rotation resisting part 3 may apply force to the lower leg worn part 2 to prevent rotation of the lower leg worn part 2 relative to the thigh worn part 1 . In other words, the rotation resistance unit 3 may provide an exercise load to a user who wants to rotate the lower leg wearable unit 2 . In addition, the rotation resistance unit 3 may be disposed on the thigh wearing unit 1 .

As an example, when the user performs an operation of stretching the leg, the lower leg wearable part 2 rotates in the first rotational direction, and the rotational resistance part 3 moves the lower leg wearable part 2 with respect to the thigh wearable part 1. A force obstructing rotation may be applied to the lower leg wearable part 2 . Accordingly, the rotation resistance unit 3 may provide an exercise load to the user's body when the user performs an operation of stretching the legs.

Here, the first rotation direction may mean that the lower leg worn part 2 rotates with respect to the thigh worn part 1 in a direction in which the angle formed between the lower leg worn part 2 and the upper thigh worn part 1 increases. , the corresponding expression may be used in the same way below.

As another example, when the user performs a leg bending operation, the lower leg wearable part 2 rotates in the second rotational direction, and the rotation resistance part 3 moves the lower leg wearable part 2 with respect to the thigh wearable part 1. A rotation assisting force may be applied to the lower leg wearable part 2 . Accordingly, when the user performs a leg bending operation, the rotation resistance unit 3 helps the user to restore the position of the user's lower leg, so that the user can smoothly prepare for the next operation.

Here, the second rotation direction may mean that the lower leg worn part 2 rotates with respect to the thigh worn part 1 in a direction in which the angle formed between the lower leg worn part 2 and the upper thigh worn part 1 decreases. , the corresponding expression may be used in the same way below.

The cable 4 may transfer the force of the rotation resistance unit 3 to the lower leg wearing unit 2 . The cable 4 may connect the lower leg wearable part 2 and the rotation resistance part 3. For example, one end of the cable 4 is connected to the fixed end 22 of the lower leg wearing part 2, and the other end of the cable 4 is the rotation resistance part 3 disposed on the thigh wearing part 1. ) can be connected to Accordingly, when the lower leg wearable part 2 rotates, the cable 4 moves together with a part of the rotation resistance part 3 by the lower leg wearable part 2 and can transmit force to the lower leg wearable part 2. However, a detailed description of this will be described later.

The central shaft member 5 may connect the wearable part 1 on the thigh and the wearable part 2 on the lower leg, and provide a rotational center of the wearable part 2 on the lower leg. Accordingly, the wearable part 2 for the lower leg can rotate with respect to the wearable part 1 for the thigh with the central shaft member 5 as the center of rotation.

The first pulley 51 may be coupled to the central shaft member 5 to support the cable 4 . For example, the first pulley 51 may be circular. In this case, when the wearable lower leg 2 rotates with respect to the wearable thigh 1, at least a portion of the cable 4 moving together with the wearable lower leg 2 winds at least a portion of the first pulley 51. As a result, the first pulley 51 can guide the smooth movement of the cable 4.

For example, the first pulley 51 may be coupled to the central shaft member 5 to be rotatable with respect to the central shaft member 5 in the form of a pulley, but is not limited thereto.

Meanwhile, although the first pulley 51 is shown in a circular shape as a whole in FIG. 1, it is not limited thereto, and only a portion of the first pulley 51 in contact with at least a portion of the cable 4 may have a circular shape. .

The second pulley 12 may be disposed on the thigh wearing part 1 to support the cable 4 . Accordingly, the second pulley 12 prevents the cable 4 from escaping to the outside of the thigh wearing part 1, and the cable 4 can move smoothly together with the lower leg wearing part 2. In addition, since the second pulley 12 supports the cable 4, the cable 4 can smoothly transmit the force of the rotation resistance unit 3 to the lower leg wearable part 2.

For example, the second pulley 12 may be rotatably coupled to the thigh wearing part 1 in the form of a pulley, but is not limited thereto.

On the other hand, although the second pulley 12 is shown in a circular shape as a whole in FIG. 1, it is not limited thereto, and only a portion of the second pulley 12 in contact with at least a portion of the cable 4 may have a circular shape. .

In addition, although the number of second pulleys 12 is shown as two in FIG. 1, it is not limited thereto and the number of second pulleys 12 may be changed as needed by those skilled in the art to which the present embodiments belong. will be self-evident.

FIG. 2 is a diagram illustrating an operating state of the exercise device shown in FIG. 1 . Referring to FIG. 2 , the operating state of the exercise device 7 shown in FIG. 1 can be seen in more detail.

Referring to FIG. 2 , the rotation resistance unit 3 may include a support unit 31 , a transfer unit 32 and an elastic unit 33 .

The support part 31 may be disposed on the thigh wearing part 1 . For example, a plurality of coupling grooves 14 are formed in the thigh wearing portion 1, and the support portion 31 is worn on the thigh by a coupling pin 31a coupled to some of the plurality of coupling grooves 14. (1) can be fixed.

The conveying part 32 is connected to the cable 4 and may be disposed on the thigh wearing part 1 so as to be slidable with respect to the thigh wearing part 1 . For example, the conveying part 32 can slide with respect to the thigh wearing part 1 in a direction toward the central axis member 5 or in a direction away from the central axis member 5 by means of the cable 4 .

The elastic part 33 may be compressed or expanded according to the movement of the conveying part 32 . For example, when the conveying part 32 moves in a direction toward the central axis member 5, the elastic part 33 is stretched, and when the conveying part 32 moves in a direction away from the central axis member 5, the elastic part 33 is elastic. Section 33 may be compressed.

For example, the elastic part 33 may include a spring, but is not limited thereto and may include various elastic bodies following Hooke's Law.

As an example, the user may wear the exercise device 7 and rotate the lower leg wearable part 2 in the first rotational direction. When the lower leg wearing part 2 rotates in the first rotational direction, the conveying part 32 can slide in a direction toward the central axis member 5 by means of the cable 4 . When the elastic part 33 is stretched by the movement of the conveying part 32, the elastic part 33 applies a force to the conveying part 32 in a direction away from the central axis member 5, so that the lower leg wearing part 2 is Rotation in the first rotation direction may be hindered.

Accordingly, the user can perform an exercise for improving muscle strength by rotating the wearable part 2 on the lower leg so that the wearable part 2 on the lower leg overcomes the force of the elastic part 33 transmitted from the cable 4 .

As another example, when the lower leg wearable part 2 rotates in the second rotational direction, the transfer part 32 may slide in a direction away from the central shaft member 5 by the elastic part 33 . Accordingly, the exercise device 7 can be restored to the state shown in FIG. 1 again.

FIG. 3 is a view showing a state in which the force of the resistance control unit of the exercise device shown in FIG. 1 is changed. Referring to FIG. 3 , a method of adjusting the force transmitted from the rotation resistance unit 3 to the lower leg wearing unit 2 can be seen in more detail. Specifically, FIG. 3 shows a state in which the support part 31 is disposed closer to the central shaft member 5 than in FIG. 1 .

The femoral wearing part 1 may include a plurality of coupling grooves 14 formed in the thigh wearing part 1 along one direction. Depending on the position where the coupling pin 31a fixing the support portion 31 is coupled to the coupling groove 14, the force applied to the lower leg wearable portion 2 by the elastic portion 33 may be different.

As an example, in a state before rotating the wearable part 2 for the lower leg, the user may move the support part 31 in a direction toward the central shaft member 5 and fix it to the wearable part 1 for the thigh. In this case, the distance between the support part 31 and the transfer part 32 decreases, and the elastic part 33 disposed between the support part 31 and the transfer part 32 can be compressed. As the elastic part 33 is compressed, the force applied by the elastic part 33 to the wearable part 2 for the lower leg in a state before the wearable part 2 for the lower leg is rotated may increase.

Accordingly, as the force of the elastic part 33 that the user must overcome in order to rotate the wearable part 2 for the lower leg increases, the exercise load performed by the user through the exercise device 7 may increase.

As another example, before rotating the wearable part 2 on the lower leg, the user may move the support part 31 in a direction away from the central axis member 5 and fix it to the wearable part 1 on the thigh. In this case, the distance between the support part 31 and the transfer part 32 is further increased, and the elastic part 33 disposed between the support part 31 and the transfer part 32 can be stretched. As the elastic part 33 is stretched, the force applied by the elastic part 33 to the wearable part 2 for the lower leg in a state before the wearable part 2 for the lower leg is rotated may be reduced.

Accordingly, as the force of the elastic part 33 that the user must overcome to rotate the wearable part 2 for the lower leg is reduced, the exercise load performed by the user through the exercise device 7 can be reduced.

That is, as described above, the exercise device 7 according to one embodiment includes a plurality of coupling grooves 14 capable of adjusting the position of the support part 31, so that the user can conveniently exercise the exercise device 7 can be adjusted. In addition, the user may be able to perform an exercise suitable for the user according to the situation by finely adjusting the exercise load applied by the exercise device 7 step by step.

Here, one side of the central axis member 5 means a part of the central axis member 5 facing the user's body when the user wears the exercise device 7, and the other side of the central axis member 5 is the center. It may mean a portion of the central axis member 5 in a direction opposite to one side of the axis member 5.

Referring to FIGS. 4 and/or 5 , it can be seen in more detail how the rotational angle of the exercise device 7 is adjusted.

The lower leg wearable part 2 may include at least one limiting groove 23 at one end 2a of the lower leg worn part 2 adjacent to the central axis member 5 . For example, the restriction groove 23 may be disposed along the circumferential direction of the central axis member 5 so as to surround the central axis member 5 .

Specifically, one end 2a of the lower leg wearing portion 2 is sequentially formed in a direction away from the thigh wearing portion 1 in the first limiting groove 23a formed at one end 2a of the lower leg wearing portion 2. , a second limiting groove 23b, and a third limiting groove 23c.

The exercise device 7 may include a limiting protrusion 24 . The limiting protrusion 24 is accommodated in the limiting groove 23 and rotates together with the wearable part 2 for the lower leg, but may prevent the wearable part 2 for the lower leg from rotating beyond a certain angle.

In addition, the rotation angle of the lower leg wearable part 2 may be different according to the location of the limiting groove 23 in which the limiting protrusion 24 is accommodated. For example, when the limiting protrusion 24 is accommodated in the third limiting groove 23c than when the limiting protrusion 24 is accommodated in the first limiting groove 23a, the rotatable angle of the lower leg wearable part 2 may be greater.

The exercise device 7 may include a fixing member 52 rotatably disposed on the central shaft member 5 and fixing the limiting protrusion 24 . The fixing member 52 may fix the limiting protrusion 24 so that the limiting protrusion 24 rotating together with the lower leg wearable part 2 is not separated from the limiting groove 23 . For example, the limiting protrusion 24 may be coupled with the fixing member 52 in a manner that is fitted to the fixing member 52 .

The femoral wearing part 1 may include a locking jaw 13 . For example, the locking protrusion 13 may protrude outward from the femoral wearing part 1 . The limiting protrusion 24 rotates together with the lower leg wearable part 2 and is caught on the locking jaw 13, thereby preventing the lower leg wearable part 2 from further rotating.

As an example, the limiting protrusion 24 may be accommodated in the first limiting groove 23a. When the lower leg wearable part 2 rotates in the first rotational direction, the limiting protrusion 24 may rotate together with the lower leg wearable part 2 . As the lower leg wearable part 2 rotates, the limiting protrusion 24 moves in a direction approaching the locking jaw 13, and the limiting protrusion 24 is caught on the locking jaw 13, thereby lowering the lower leg wearing part 2. rotation can be limited.

As another example, the limiting protrusion 24 may be accommodated in the third limiting groove 23c. When the lower leg wearable part 2 rotates in the first rotational direction, the limiting protrusion 24 rotates together with the lower leg wearable part 2 and may move in a direction approaching the locking jaw 13 .

When the limiting protrusion 24 is accommodated in the third limiting groove 23c, the limiting protrusion 24 must move to be caught on the locking jaw 13 than when the limiting protrusion 24 is accommodated in the first limiting groove 23a. distance may increase. Accordingly, the rotatable angle of the lower leg wearable part 2 may be further increased when the limiting protrusion 24 is accommodated in the third limiting groove 23c than when the limiting protrusion 24 is accommodated in the first limiting groove 23a.

As described above, the exercise device 7 according to an embodiment can provide a user with various ranges of motion by stepwise adjusting the rotational angle of the lower leg wearable part 2 with respect to the thigh wearable part 1 .

For example, the piston 342 may move in a direction toward the second gear 36 or away from the second gear 36 inside the inner cylinder 341 .

The piston 342 may include a check valve 342a. For example, the check valve 342a may be closed when the piston 342 moves in a direction toward the second gear 36 and opened when the piston 342 moves in a direction away from the second gear 36. there is.

The restoration spring 343 may press the piston 342 away from the second gear 36 .

The discharge groove 344a formed in the outer cylinder 344 may be inclined with respect to the longitudinal direction of the outer cylinder 344 . Accordingly, the area of the outer cylinder 344 covering the discharge hole 341a may be changed according to the rotation of the outer cylinder 344 . For example, the discharge groove 344a may have an obliquely perforated outer surface of the outer cylinder 344, but is not limited thereto.

As an example, an area of the outer cylinder 344 covering the discharge hole 341a may be increased by rotation of the outer cylinder 344 . Accordingly, discharge of the fluid from the discharge hole 341a may be inhibited, and flow resistance inside the rotation resistance unit 3 may increase.

In other words, if the area of the outer cylinder 344 that covers the discharge hole 341a increases due to the rotation of the outer cylinder 344, the flow resistance of the rotational resistance unit 3 that the user must overcome increases, so the user can exercise more strongly. Exercises with load can be performed.

As another example, the area of the outer cylinder 344 covered by the discharge groove 344a and the discharge hole 341a may be reduced by rotation of the outer cylinder 344 . Accordingly, fluid is smoothly discharged from the discharge hole 341a, and flow resistance inside the rotation resistance unit 3 can be reduced.

In other words, if the area of the outer cylinder 344 that covers the discharge hole 341a is reduced by the rotation of the outer cylinder 344, the flow resistance of the rotational resistance unit 3 that the user must overcome decreases, so the user can move more weakly. Exercises with load can be performed.
