A pressure sensor (not shown) capable of measuring the degree of external force may be provided. Accordingly, when the user performs the squat exercise, the degree of pressure applied to the second body 220 may be sensed, and through this, it is possible to estimate whether the user's squat exercise is performed in a correct posture. Although not shown, the sensed pressure may be output through a display or speaker of smart rehabilitation exercise equipment, etc., and whether or not the exercise posture calculated according to the sensed pressure is appropriate, and a posture correction guide according to the sensed pressure are also used through the display or speaker. Can be output.

Hereinafter, the operating mechanism of the calf pressing unit 200 will be described with reference to FIG. 4.

Figure 4 (a) is a state in which the user using the squat exercise assisting device 1000 takes a basic squat sitting posture on the calf pressing unit 200, and Figure 4 (b) shows the middle of the user's sitting position. This is shown, and Figure 4(c) shows the state in the posture where the user fully arose.

Referring to Figure 4 (a), the calf pressing unit 200 basically takes the same structure as in Figure 4 (a). This is a state in which the angle formed by the second body 220 with respect to the first body 210 due to gravity is the maximum, and the elastic part 230 is not compressed. At this time, the calf pressing unit 200 contacts the user's calf, but the first body 210 and the second body 220 are not close, so the second body 220 is moved by the elastic unit 230 to the user’s calf. Do not press the side. The user can sit down so that the calf corresponds to the second body 220 of the calf pressing unit 200 and start the squat operation.

Referring to FIG. 4B, this is a process that occurs in a sitting position of the user squat. At this time, the user's calf pushes the second body 220, and the elastic part 230 is compressed as the second body 220 approaches the first body 210. Accordingly, the elastic force of the elastic portion 230 increases, and the force by which the elastic portion 230 pushes the second body 220 increases. Accordingly, the force of the second body 220 pushing the user's calf increases.

As described above, the closer the second body 220 is to the first body 210, that is, the closer the user is to the posture that occurred in the sitting posture of the squat, the greater the elastic force of the elastic part 230. Accordingly, the force by which the second body 220 pushes the user's calf is also simultaneously increased.

4C shows a state in which the user stands up completely. At this time, the user's calf is pushing the second body 220, and the first body 210 is fixed to the base portion 100, so that the elasticity between the first body 210 and the second body 220 The unit 230 is in a very compressed state. Accordingly, the elastic part 230 presses the second body 220 with a strong force, and this force leads to a force that the second body 220 presses the user's calf. Accordingly, when the user's calf is fully awakened from the squat posture as described above, the user's calf is subjected to the greatest pressure by the calf pressing unit 200. That is, the pressure of the second body 220, which is changed from the state (a) of FIG. 4 to the state (b) and (c), and is pressed against the user's calves, gradually increases.

In the squat exercise assisting apparatus 1000 according to an embodiment of the present invention, when the user raises the calf in a position toward the second body 220, the second body 220 is an elastic part 230 to press the user's calf. By being pressurized by, it can have a similar effect to squat with heavy weight.

In addition, by the force of the second body 220 pressing the calf, the user does not simply need muscle strength in the calf, but in order to straighten the bent knee, the thigh also needs a greater force than the original squat force. . Therefore, if the squat exercise assisting device 1000 according to an embodiment of the present invention is used, a similar effect can be obtained without squat with a heavy weight. This reduces the risk of injuries that can occur when squatting with a real heavy weight.

In addition, as the other end of the second body 220 is closer to the first body 210, the elastic part 230 of the squat exercise assisting device 1000 according to an embodiment of the present invention is attached to the second body 220. By applying a greater elastic force, the user is not in an unstable posture in which the user is sitting, but a user with a relatively stable posture applies force to the user's calf in a standing posture, so that the user loses the center while using the squat exercise assisting device 1000 Can reduce accidents.

Meanwhile, the calf pressing unit 200 may further include a locking ring 242. The locking hook 242 may fix the second body 220 near the first body 210.

Referring to FIG. 2, the locking ring 242 may be hinged 241 with the second surface 212 on the upper side of the second surface 212 of the first body 210. The locking ring 242 may be disposed to overlap the second surface 212 of the first body 210 when using the calf pressing unit 200. The second bar 232 may protrude outward from the first surface 222 of the second body 220. In addition, the locking ring 242 may be provided with a locking ring groove 243 through which the second bar 232 can be locked.

Referring to FIG. 3, the second bar 232 is caught in the locking hook groove 243 so that the second body 220 may be maintained at a fixed distance from the first body 210.

Through this, when the user is not using the calf pressing unit 200, by placing the second body 220 close to the first body 210 using the locking ring 242, the first body 210 and the 2 It is possible to prevent accidents such as an object being caught in the space between the body 220.

5 is a view showing a squat exercise assisting apparatus according to another embodiment of the present invention. Contents overlapping with those described in FIGS. 1 to 4 will be omitted for convenience of description.

The squat exercise assisting apparatus 2000 according to another exemplary embodiment of the present invention may include a first body 1210, a second body 1220, and an elastic part 1230.

The first body 1210 may form a certain angle with respect to the base part 1100 and may be formed to be rotatable or fixed with respect to the base part 1100. The first body 1210 may include a first surface 1211 fixed to the base portion 1100 and a second surface 1212 formed at an angle of 90 degrees to the first surface 1211. In this case, the length of the second surface 1212 may be short. Through this structure, not only the size of the product can be reduced, but also the production cost can be lowered. Meanwhile, unlike in the drawings, the method in which the first surface 1211 of the first body 1210 is coupled to the base unit 1100 may be coupled in the same manner as in the embodiments described in FIGS. 1 and 2. .

The second body 1220 has one end hingedly coupled to the lower end of the first body 1210 so that the second body 1220 is rotatable with respect to the first body 1210, and the other end is rotatable so that the angle formed with the base part 1100 changes. Can be done.

In this case, the fixing protrusion 1260 may be formed on the inner surface of the second body 1220. Specifically, referring to FIG. 5, fitting grooves 1250 into which an extension plate 1300 to be described later can be inserted may be formed on both sides of a surface of the second body 1220 facing the base 1100. . Further, a fixing protrusion 1260 having an uneven shape may be formed on an inner surface of the fitting groove 1250.

The extension plate 1300 may be fixed to the second body 1220 by the fixing protrusion 1260 described above. Specifically, a fitting protrusion 1330 may be formed on the side of the extension plate 1300 to be fitted to the fixing protrusion 1260 described above. Through this, when the extension plate 1300 is inserted into the fitting groove 1250 and pressed, the fitting protrusion 1330 engages with the fixing protrusion 1260, and the extension plate 1300 may be fixed to the second body 1220. . As a result, the second body 1220 may be formed to be elongated in the length direction.

That is, the squat exercise assisting apparatus 2000 according to an embodiment of the present invention further includes an extension plate 1300 that is formed long in the length direction of the second body 1220, so that the entire calf fits the body ratio of the user. Can pressurize.

Meanwhile, the elastic part 1230 may be disposed between the base part 1100 and the lower end side of the second body 1220. As the angle between the second body 1220 and the base portion 1100 increases, an elastic force applied to the second body 1220 may increase. For example, the elastic body 1234 of the elastic portion 1230 may be formed of a tension spring.

Through this, as described in FIG. 4, when the user performs the squat while the calf is placed on the side of the second body 1220, the second body 1220 is moved away from the base portion 1100 and is stretched.
