Leg stretching device according to the present invention by stretching or unwinding the wire (70, 71) up and down by moving the leg support (50, 51) in the horizontal direction to stretch or stretch the user's legs. Various materials such as metal, synthetic resin, or wood can be used as the material of the leg stretching device, and use a material with high strength to stably support the stretching exercise of the user and for durability.

The vertical frame 10 is disposed in the vertical direction to support the movement of the leg stretching device and to support the movement of the wires 70 and 71. The lower end of the vertical frame 10 is coupled to the support 20 for stably supporting the leg stretching device on the floor. In addition, the horizontal frame (30, 31) is coupled to extend in the horizontal direction of the vertical frame 10 to support the movement of the wire.

The chair 60 is a space for the user to sit for the stretching exercise, is coupled to the front of the vertical frame 10 and the horizontal frame (30, 31).

The leg rests 50 and 51 are arranged while being exposed to the front of the chair so that the user can put both legs in a state coupled to the chair 60. The leg rests 50 and 51 are provided with two left and right so that the user can put both legs. Hereinafter, an end exposed to the front of the chair 60 among the both ends of the leg rests 50 and 51 is referred to as a 'first end' and an end coupled to the chair is referred to as a 'second end'. The second ends of the leg rests 50, 51 are pivotally coupled to the chair 60, preferably to be pivotally coupled to the bottom of the chair. Accordingly, the leg supports 50 and 51 may be rotated in the left and right horizontal directions along the rotation axis to open or retract the legs. Preferably, the two leg rests 50 and 51 are configured to be extended up to 180 ° to 200 °. In addition, leg fixing parts 90 and 91 are disposed at the first ends of the leg rests 50 and 51 to fix the leg of the user, which is placed on the leg rest, respectively. Further, wires 70 and 71 for rotating the leg supports in the horizontal direction are respectively coupled to the first ends of the leg supports 50 and 51, respectively.

The leg fixing parts 90 and 91 may be configured in the form of sidewalls protruding upward so that the user's legs cannot move left or right, or may be configured in the form of a belt so as to stably bind the user's legs. Preferably, the leg fixing portion (90, 91) is to form a wide width in the front and rear direction so that the user's ankle and calf can be wrapped and fixed together. In addition, the lower portion of the leg fixing portion (90, 91) includes a coupling portion (90a, 91a) formed in the front and rear direction so that the leg support (50, 51) is fitted to secure the leg fixing portion to the leg support through the coupling portion In the state in which the leg rests 50 and 51 are fitted to the coupling parts 90a and 91a, the leg fixing parts 90 and 91 are moved along the leg rests in the front and rear directions to adjust the position according to the user's height. In addition, the bottom of the coupling portion (90a, 91a) and the leg support (50, 51) forms a screw groove step by step according to the user's height, and by tightening the screw (not shown) before and after the leg fixing portion (90, 91) Adjust the position of the direction so that it can be fixed. On the other hand, as described above, when the legs 50 and 51 are coupled to the bottom of the chair 60, the height of the legs and the height of the chair are different by the thickness of the chair, so that the leg fixing parts 90 and 91 are It is formed to be as high as the height of the chair above the leg rests 50 and 51 so that the user's legs are positioned equal to the height of the chair to provide comfort. Therefore, the leg fixing parts 90 and 91 form a '┖┙' shape in the left and right directions.

The wires 70 and 71 are connected and disposed over the vertical frame 10 and the horizontal frames 30 and 31 with one end coupled to the leg supports 50 and 51. In the following description, one end of the two ends of the wires 70 and 71 that engages with the leg rests 50 and 51 is called a 'first end' and the other end is called a 'second end'. Two wires 70 and 71 are provided to be coupled to the two leg rests 50 and 51, respectively. Thus, the two leg rests 50 and 51 can be moved independently. Each wire 70, 71 is wound around a plurality of pulleys 80, 81 mounted on the vertical frame 10 and the horizontal frames 30, 31, installed over the vertical frame and the horizontal frame, and moved along the pulley. The pulleys 80 and 81 convert the force transmitted in the vertical direction to the wires 70 and 71 in the horizontal direction. The pulleys 80, 81 are respectively disposed at the upper end of the vertical frame 10, between the vertical frame and the horizontal frame 30, 31, and at the left and right ends of the horizontal frame 30, 31, respectively. Are orthogonal to each other. That is, the pulleys 80 and 81 disposed at the upper end of the vertical frame 10 rotate in the vertical direction, and the pulleys disposed between the vertical frame and the horizontal frame 30 and 31 rotate in the horizontal direction and the horizontal direction. The pulleys disposed at the left and right ends of the frame rotate in the front and rear horizontal directions. Accordingly, the vertical force applied to the second ends of the wires 70 and 71 is converted to the force in the front and rear directions through the respective pulleys 80 and 81 to move the leg supports 50 and 51. The second ends of the wires 70 and 71 are provided with handles 40 and 41, respectively, for the user to hold the wires.

Referring to the operation of the leg stretching device according to the present invention is as follows.

With the two leg rests 50, 51 of the leg stretching device gathered in the center, the user is seated on the chair 60 and the legs are placed on the leg rests. Then, the ankles or calves are fixed to the leg fixing parts 90 and 91.

When the user pulls down the handles 40 and 41 located at the upper end of the vertical frame 10, a second force of the wires 70 and 71 is applied in the vertical direction to pull the wires down. The vertical force applied to the second ends of the wires 70 and 71 is converted to the force in the left and right direction through the pulleys 80 and 81 disposed between the vertical frame 10 and the horizontal frames 30 and 31. In addition, while passing through the pulley disposed at the left and right ends of the horizontal frame, it is converted to the force in the front-rear direction and transmitted to the first ends of the leg supports 50 and 51. Since the second ends are coupled to the chair 60 with the rotation shaft, the leg supports 50 and 51 are gradually opened while rotating in the horizontal direction by the force transmitted by the wires 70 and 71. Therefore, both legs of the user mounted on the leg rests 50 and 51 are gradually opened. At this time, since the two wires 70 and 71 are connected to the two leg rests 50 and 51, respectively, the two leg rests may be moved independently of each other by varying the pulling force of the handles 40 and 41. On the other hand, if you feel the pain by stretching the legs too wide while stretching the force to pull the handle (40, 41) is reduced to the force applied to the leg support (50, 51) it is possible to retract both legs.

Variant

In the above description, an embodiment in which the user moves the leg supports 50 and 51 by directly pulling the handles 40 and 41 is different. Alternatively, the second end of the wires 70 and 71 is interlocked with a separate drive motor to drive the same. It can also be configured to move the leg support by automatically pulling or releasing the wire by controlling the motor to generate one or the opposite direction of driving force. Therefore, the user can move the leg rests 50 and 51 as much as desired by only operating a switch, and can exercise more conveniently.

Leg stretching device according to the present invention has the following effects.

1. You can stretch as conveniently as you want by yourself without the help of others.

2. You can adjust the intensity freely according to the user's flexibility, and if the pain is severe, you can immediately release the stretching state to prevent injury.

3. Stretching while sitting on a chair, the user can exercise in a more comfortable posture without shaking the center.

4. It is economical and does not generate noise because it operates by user's power without extra power, so it can be used conveniently regardless of place or time.

5. Since the two legs can be moved independently with two wires, the two legs can be moved independently so that only one leg can be stretched or the angle can be varied.

6. Using the leg fixing part to fix the user's leg to the leg support, so that the slight pain during exercise to prevent the foot from being removed from the leg support to maintain the correct posture can improve the exercise effect and prevent injury.

7. If you have a separate drive motor to be configured to wind or unwind the wire, the foot rest can be moved automatically only by the operation of the switch.

8. It can be used for aerobics, dance, ballet, taekwondo, yoga, and fitness that require flexibility of legs.
