Description

Speed-Adjustable Folding Door System}

The present invention relates to a folding door system capable of adjusting speed, and more particularly, to a folding door system capable of adjusting speed in which the opening and closing speed can be adjusted in the process of opening and closing the folding door.

A conventional door refers to a structure composed of a door leaf and a door frame, and refers to a structure made to be opened and closed at a place where people enter and exit, such as a boundary between places in a building or an entrance of a building.

These doors serve to connect or divide places or to open spaces, and recently, folding doors are used as doors to maximize the role of securing space and giving a sense of openness to spaces.

The folding door is provided with a wire and a damper inside so that the door can be opened and closed by sliding to the side, and a wide space can be secured by the folded door, enabling efficient use of space even in a narrow space.

However, the wire has a disadvantage in that, when the folding door is light, the door operates quickly and generates noise due to an impact against the damper, and in severe cases, the damper or other parts are damaged and the durability is shortened.

In addition, in the process of installing the folding door, there is a disadvantage in that frequent replacement is required because the durability of the parts connecting the door rapidly decreases as problems arise in the construction environment and the error of the constructor.
