Description

  The present invention is a folding door-type drawing door that opens and closes a pair of folding doors, and if one side folding door is opened and closed, the other side folding door is also opened and closed in conjunction with it. The present invention relates to an interlocking draw-type folding door device that is easy to use for a user.

  In general, since the draw door can secure a relatively wide area of the opening when opened, it is preferably installed, for example, in hospitals and other facilities where stretchers and beds pass, Sliding door type doors need to secure a retracting space for sliding doors along the walls on the left and right sides of the opening, so there are usually folding door type sliding doors in places where there are no walls next to the opening. It is attached.

However, in the case of folding door type drawer doors, for example, when opening, normally one side of the folding door is opened by folding one side of the door, and then the other side of the folding door is opened by folding the other side of the door. For the first time, for example, a disabled person using a wheelchair or a care recipient who wants to open and close in the same way must move left and right each time. Has the disadvantage of not being easy and inconvenient. Therefore, some of the conventional draw-type folding door devices have a structure that automatically opens and closes by interlocking the left and right folding doors by driving an electric motor so that people with disabilities can easily open and close them. It is done.
