摘要

The folding door has multiple hinged sheets approaches their faces in continuous open position. Each sheet provides a puller in one of their faces. One puller acts from one of the sheets to open the door and another puller from another sheet to close the door. The sheets are provided with a head-holder bearer of an upper vertical roller and a lower horizontal roller, which are guided by two separate rolling lanes fixed to pre frames. Each head-holder relates to one sheet by a hinge, which occupies the full height without buckling.
