Pull-up aid apparatus to assist pull-up easily}

The present invention relates to a pull-up assistive device that helps to easily do pull-ups. More specifically, the present invention relates to a pull-up assistive device that helps beginners to quickly learn the pull-up position and stimulation area by supporting their feet when performing pull-up exercises while hanging on a bar by themselves, and to help them develop their back muscles. This is about a pull-up assistive device that helps you do pull-ups easily.

The exercise, commonly called a pull-up or chin-up, involves holding a bar with your hands and raising your body so that your chin rises above the bar. It is mainly used as a bodyweight exercise to stimulate the back muscles.

At this time, pull-ups stimulate the back muscles by raising the chin over the bar through contraction and relaxation of the back muscles, not the arms. For beginners, the back muscles are not properly developed, making pull-ups impossible or relying on the arm muscles.

If you do pull-ups based on your arm muscles, your back muscles will not be stimulated, so you will not be able to grow your back muscles even if you do pull-ups for a long time, and your pull-up posture will be messed up, so you need to learn the pull-up posture and stimulation position from the first time you start doing pull-up exercises. There is a need.

However, as mentioned earlier, because beginners' back muscles are underdeveloped, they cannot do even one pull-up at first, so there is a problem that they cannot develop their back muscles through pull-ups.

For this purpose, a conventional method is to wrap a fitness band around an iron bar and then support the feet to do a pull-up, as shown in Figure 1, so that part of the body weight is supported by the band so that one can easily do a pull-up. It is suggested that by holding and supporting the feet of the person, the body weight generated during pull-ups can be reduced, allowing the user to learn pull-ups.

However, when using a fitness band as in the past, you can exercise alone, but there is a problem that your posture is messed up due to the elasticity of the band and you have to prepare several bands depending on your body weight.

Additionally, when two people do pull-ups as a team, there is a problem in that they have to give up on pull-ups because it is difficult to exercise alone.

Korean Patent Publication No. 10-2020-0038575, which aims to solve this problem, relates to a steel bar auxiliary device. As shown in Figure 2, the iron bar attachment part 130 is fixed to the iron bar and then attached to the footrest part 140. It is designed to receive support when the user raises his or her feet and then does a pull-up using the force generated by the spring formed inside.

However, in the case of the prior art, since the force applied from the footrest is based on the elastic force formed inside, there was a problem in that if the user's body weight was greater than the elastic force, the user could not receive assistance from the elastic force and thus could not receive pull-up assistance.
