An ankle-bending exercise apparatus according to the present invention is used to perform an ankle-bending exercise while sitting with the knees straight, and allows each user to adjust the maximum height to which the user can raise the user's feet in a straightened-out state while sitting according to the physical condition of the user, thus making it possible to raise the feet to the maximum height allowed by the muscles at the back of the feet and bend the ankles when the muscles at the back of the legs are pulled to the maximum extent and thereby maximizing the ankle-bending effect. Moreover, the exercise apparatus is provided with a backrest for preventing the upper body of the user from leaning backward when the exercise apparatus is being operated, thus preventing the upper body from leaning backward so that the muscles at the back of the feet relax and reduce the effect of the exercise when a footrest is rotated in order to bend the feet, and improving the stretching effect.

Description

ankle twister

[0001] The present invention relates to exercise equipment. More specifically, it relates to an exercise equipment that allows the user to sit with their knees extended and their feet turned toward the user with their ankles as an axis.

[0002] Conventional exercise equipment requires the user to sit with their knees extended, pull on a handle, and bend their feet toward the body, using the ankles as an axis. This method is known to be more efficient than placing the feet on the floor and pulling on the handles. It's important to raise the feet as high as possible and bend the ankles to maximize the stretch of the muscles in the back of the legs. However, this method limits the maximum stretch height depending on the user's physical strength and muscle power, making it unsuitable for all users.

[0003] Furthermore, conventional exercise equipment tends to tilt the upper body backward when the user pulls the handle, making it difficult to maintain tension in the muscles at the back of the legs. This reduces the muscle stretching effect when the ankles are fully flexed. Therefore, there is a pressing need to find new ways to prevent the upper body from tilting backward and enhance exercise effectiveness.

[0004] The present invention was developed to solve the problems of the prior art as described above, and the purpose of the present invention is to provide an ankle-bending exercise device formed with a floor that can adjust the height of the feet to suit each user according to the height at which each user can raise his or her feet in response to a fixed floor.

[0005] In addition, the purpose of the present invention is to provide an ankle-bending exercise machine that increases efficiency by allowing the user to support the back by appropriately adjusting the position according to the height or physical condition of each user when operating the exercise machine, so that the effect of raising the feet is offset when the upper body is leaned back when operating the exercise machine by raising the feet to a higher height.

[0006] To maximize the effect of ankle bending, you should sit with your knees straight and raise your feet as high as your back leg muscles allow, and then bend your ankles when the back leg muscles are fully stretched.

[0007] In order to achieve the above purpose, an ankle-breaking exercise device according to one embodiment of the present invention has the following configuration.

[0008] It is an exercise machine that allows you to sit with your knees extended and do ankle bending exercises.

[0009] A fixed part (2) that fixes the moving part (1);

[0010] A bottom part (11) that supports the user's buttocks when in use;

[0011] A moving part (1) having a moving axis (6) formed in an up-and-down direction, a rotating axis (3) provided at the upper end of the moving axis (6), and a heel sole (7) extended from the moving axis toward the bottom (11) to support the user's foot when in use;

[0012] It has a foot plate (4) that is attached to the rotation axis (3) at one end and rotates around the rotation axis (3).

[0013] At this time, the fixed part (2) further includes an upper and lower adjustment part (12) that acts on the lower part of the moving shaft (6) to adjust the height of the moving shaft (6) up and down, and a fixed support (9) that supports the moving shaft (6).

[0014] The vertical movement of the above moving part (1) is arranged so as not to interfere with the bottom part (11).

[0015] The exercise device according to the present invention can be used by rotating the foot plate (4) around the rotation axis (3) while adjusting the height of the heel sole (7) using the upper and lower adjustment part (12) to the maximum height allowed by the muscles of the back of the leg.

[0016] Meanwhile, a handle (5) may be further provided at the other end of the footrest (4), and may be extended by being bent at a predetermined angle toward the bottom (11) based on the footrest (4), or a separate motor and controller for electrically rotating the footrest (40) may be further provided.

[0017] Meanwhile, a backrest (13) supporting the user's upper body is provided at the opposite end of the moving part (1) of the floor part (11).

[0018] A floor adjustment part (14) that adjusts the distance between the moving axis (6) and the backrest (13) by adjusting the length of the floor part (11) may be further provided.

[0019] Instead of the floor adjustment unit (14), a backrest adjustment unit (15) for adjusting the distance between the moving axis (6) and the backrest (13) may be provided.

[0020] Meanwhile, a motor may be further provided to electrically drive the upper and lower adjustment unit (12) to adjust the upper and lower height of the moving shaft (6).

[0021] In the past, the maximum effect of ankle bending could be achieved by raising the foot to the maximum height allowed by the muscles at the back of the foot and bending the ankle when the muscles at the back of the leg were maximally stretched. However, the problem was that the maximum height to which the foot could be raised while sitting and straightened varied depending on the user, and thus the exercise equipment had a problem in that it was impossible to limit the maximum height to which the foot could be raised.

[0022] According to the present invention, the maximum height at which the user can sit and straighten their feet can be adjusted, thereby increasing the effectiveness of the exercise.

[0023] Additionally, the backrest can be adjusted to fit the user's back according to their height and physical condition, thereby preventing the upper body from leaning back, thereby achieving the maximum stretching effect.

[0044] Hereinafter, an example of implementing the ankle-breaking exercise device of the present invention will be described through a specific embodiment.

[0045] Figure 1 is a perspective view of an ankle-bending exercise device according to the present invention, and Figure 2 is a longitudinal cross-sectional view of an ankle-bending exercise device according to the present invention.

[0046] Referring to FIGS. 1 and 2, the effect of ankle flexion is maximized when the ankle is flexed when the muscles in the back of the leg are maximally pulled while sitting with the knees straight and the feet raised to the maximum height allowed by the muscles in the back of the leg. Therefore, the ankle flexion exercise device of the present invention has the following configuration so that each person can raise the feet to their optimal height.

[0047] A fixed part (2) that fixes the moving part (1);

[0048] A bottom part (11) that supports the user's buttocks when in use;

[0049] A moving part (1) having a moving axis (6) formed in an up-and-down direction, a rotating axis (3) provided at the upper end of the moving axis (6), and a heel sole (7) extended from the moving axis toward the bottom (11) to support the user's foot when in use;

[0050] A footrest (4) is provided, one end of which is connected to the above-mentioned rotation axis (3) and rotates around the above-mentioned rotation axis (3).

[0051] The above fixed part (2) further includes a vertical adjustment part (12) that acts on the lower part of the moving shaft (6) to adjust the height of the moving shaft (6) up and down, and a fixed support (9) that supports the moving shaft (6).

[0052] The above moving part (1) is positioned so that the vertical movement does not interfere with the bottom part (11), and when in use, the height of the heel sole (7) is adjusted using the vertical adjustment part (12) to the maximum height allowed by the muscles in the back of the leg, and the footrest (4) is rotated around the rotation axis (3).

[0053] Figure 3 is a cross-sectional view of the preparation stage of the ankle bending exercise device according to the present invention.

[0054] According to Fig. 3, it can be confirmed that the preparation stage before using the exercise equipment is depicted, in which the user places the sole of the foot on the footrest (4), places the foot on the heel (7), sits with the knees stretched out on the floor (11), and adjusts the position of the backrest (13) so that it touches each person's back in order to use the exercise equipment.

[0055] Figure 4 is a cross-sectional view of the foot height adjustment stage of the ankle bending exercise device according to the present invention.

[0056] In Fig. 4, it is exemplified that the height of the heel sole (7) is adjusted to the optimal height by operating the upper and lower adjustment unit (12) up and down in the preparation stage shown in Fig. 3.

[0057] Figure 5 is a cross-sectional view of a step of using an ankle bending exercise device according to the present invention.

[0058] Figure 5 illustrates an exercise device in which the heel sole (7) of Figure 4 is adjusted to the optimal height for ankle bending to suit the physical condition of each user, and the backrest (13) is adjusted to contact each user's back. The step of implementation is illustrated to maximize the effect by bending the foot by pulling the handle (5) or controlling the controller to rotate the footrest (4).

[0059] The bottom part (11) can be formed by combining an inner bottom (16) and an outer bottom (17).

[0061] At this time, when the feet are placed on the heel (7), the knees are straightened, the upper body is raised, and the position of the back is different for each person depending on the height and body size when sitting on the bottom part (11) of the exercise machine, so a bottom adjustment part (14) can be additionally provided to adjust the length of the bottom part (11) to suit each individual so that the backrest (13) touches the back of each person.

[0062] By using the floor adjustment part (14), the user can adjust the backrest so that it touches his or her own back, thereby preventing the upper body from leaning backwards when stretching.

[0063] Meanwhile, in the example of Fig. 2, the length of the floor part (11) was adjusted by the floor adjustment part (14) so ​​that the backrest (13) touches each user's back, but in the modified example shown in Fig. 6, the floor part (11) and the backrest (13) are formed separately, and a backrest adjustment part (15) that can adjust the position of the backrest (13) to a position where it touches each user's back is formed between the floor part (11) and the backrest (13), so that the user can use the backrest (13) by adjusting it so that it touches each user's back.

[0064] That is, compared to the example of Fig. 2, the floor adjustment part (14) can be replaced with a backrest adjustment part (15).

[0065] Meanwhile, the positions of the upper and lower adjustment unit (12), the position adjustment unit (14), and the backrest adjustment unit (15) can be adjusted by manual operation of the user, but a separate motor for electric driving, a wireless controller for controlling the motor, and a separate power supply for supplying power to the motor may be further provided.

[0066] The upper and lower adjustment unit (12), the floor adjustment unit (14), and the backrest adjustment unit (15) can optionally use elements such as a rack and pinion gear, a worm and worm gear, a screw jack, a hydraulic jack, a mechanical jack, and an air jack.
