[0075] In addition, in the vertical pulldown machine 100 according to one embodiment of the present invention, when the distance from one end of the support frame 110 closest to the seat 170 to the other end closest to the main frame 120 is defined as a width (W), the center of the seat 174 may be located within a range of 34 to 43% of the width (W) from the end closest to the seat 170, and the rotation axis of the rotating unit 140 may be located within a range of 76 to 85% of the width from the end closest to the seat 170. Furthermore, when the distance from the floor to the top end of the rotating unit 140 is defined as a height (H), the center of the weight plate may be located within a range of 13 to 22% of the height (H) from the floor, the rotation axis of the rotating unit 140 may be located within a range of 63 to 72% of the height (H) from the floor, and the grip unit 160 may be located within a range of 76 to 85% of the height (H) from the floor. By configuring the vertical pulldown machine 100 as described above, the grip portion can rotate linearly above the user's head, enhancing the exercise effect.

[0076] The operation of the vertical pulldown machine 100 of the present invention will be described below with reference to FIG.

[0077] FIG. 8 is a diagram illustrating the operation of a vertical pulldown machine according to one embodiment of the present invention.

[0078] Referring to FIG. 8, (a) shows a state before the user lowers the grip portion 160, and (b) shows a state after the user has lowered the grip portion 160.

[0079] First, a user can attach a weight plate of a desired weight to the weight unit 130. Then, the handle 161 can be adjusted to a desired angle using the handle angle adjustment unit 162 and attached to the weight unit 130. Next, the user sits on the seat 170 with their back to the main frame 120 and can adjust the height of the seat 174 to suit their body size. Then, the angle of the knee support unit 176 can be adjusted using the support angle adjustment unit 177 to secure the user's legs. Depending on the user's needs, the user can grip the handle 161 with one or both hands and lower the grip unit 160 to move one end of the rotating unit 140 from the raised position (see FIG. 8(a)) to the lowered position (see FIG. 8(b)), thereby lifting the weight plate of the weight unit 130 and performing exercise. Of course, the above-described operations can also be performed while looking at the main frame 120. When a user grips the grip part 160 and lowers it, the rotating part 140 connected to the grip part 160 rotates, and the weight part 130 connected to the connecting part 150 is lifted by the rotation of the rotating part 140. If a user desires to change the weight during exercise, the weight can be changed by adjusting the length of the connecting part 150.

[0080] As described above, according to one embodiment of the present invention, the grip portion rotates linearly above the user's head, which has the effect of enhancing the effectiveness of exercise.

[0081] In addition, the vertical pulldown machine according to one embodiment of the present invention is provided with a handle angle adjustment unit, which allows the user to adjust the handle angle to various angles according to their needs, select a grip type, and perform concentrated exercises targeting specific parts of the body. Furthermore, the user can select one-arm or two-arm exercises to perform the exercise, which has the effect of allowing the user to perform customized exercises according to the purpose of the exercise.

[0082] In addition, the vertical pulldown machine according to one embodiment of the present invention can adjust the height of the seat, the angle of the knee support, the angle and position of the chest support, etc., thereby making it possible to accommodate a variety of user body sizes.

[0083] Although one embodiment of the present invention has been described above based on limited examples and drawings, the embodiment of the present invention is not limited to the above example, and various modifications and variations can be made by those skilled in the art based on such description. Therefore, one embodiment of the present invention should be understood only by the scope of the following claims, and all equivalent or similar modifications are considered to fall within the scope of the present invention.
