It relates to an invention to adjust the.

In general, weight training is a resistance training to develop strong physical strength through muscle development, lifting a barbell of various weights, or applying a load to the muscle with a universal gym or nautilus, and various weight apparatuses are used for weight training. .

Among them, weight devices that are connected to the actuator through cables and pulleys connected to the weight blocks are used to develop the required muscles. These weight devices are mainly used in chairs where the user sits on a chair or has a backrest. It is designed to allow weight training while lying at an angle.

The weight mechanism chair can adjust the height according to the user's body shape to suit the movement, mainly the hydraulic cylinder such as shock absorber is mounted to the lower part of the chair to operate the lever while sitting on the chair valve When the chair is opened, the chair is lowered, and when the valve is opened in the standing state, the chair is gradually raised, and the height of the chair is adjusted by closing the valve by closing the lever at the required height.

The above-described hydraulic cylinder is configured to slowly raise and lower the chair by using oil resistance. When the chair is mounted vertically, the height adjustment operation is performed smoothly, but the lever is mounted when the chair is inclined. Even if the valve is opened by operating the closed and raised operation of the chair is not made smoothly.

That is, since the force of the spring mounted inside the cylinder is controlled by hydraulic pressure, the restoring force of the spring is remarkably lowered, so that it is difficult to raise the chair in the inclined direction even when the valve is opened.

In addition, when sitting on the inclined chair mounted at an inclination of about 40 °, it was not possible to apply the exact load in the vertical direction, and thus the chair supported by the spring and the hydraulic force could not be lowered.

Therefore, the user has to adjust the height by operating the lever while pressing the chair vertically or pulling it up by hand, which makes the height adjustment work very inconvenient, and the hydraulic cylinder has a complicated structure and oil inside the airtight container. Because of the need to inject, the overall manufacturing cost of the height adjustment device is raised, such as the closing.
