Document Type and Number:
WIPO Patent Application WO/2019/076172
Kind Code:
A1
Abstract:
An overlapped type platform screen door, relating to the field of platform safety door equipment, and comprising a door sill (2), a side vertical column (61), a middle vertical column (62), a fixed door (1), and an overlapped sliding door; the side vertical column (61), the middle vertical column (62), the fixed door (1), and the overlapped sliding door are all disposed on the door sill (2), and the fixed door (1) is fixed between the side vertical column (61) and the middle vertical column (62); the overlapped sliding door comprises an inner sliding door (4) and an outer sliding door (3); the fixed door (1), the inner sliding door (4), and the outer sliding door (3) are arranged layer by layer; when the overlapped sliding door is folded, the fixed door (1), the inner sliding door (4), and the outer sliding door (3) are sequentially overlapped from inside to outside; when the inner sliding door (4) and the outer sliding door (3) are horizontally and slidably expanded, one side of the outer sliding door (3) is connected to an edge frame, and two sides of the inner sliding door (4) are in contact with the middle vertical column (62) and the other side of the outer sliding door (3). Under the requirement of a same net opening degree, the width of the fixed door next to the sliding door can be reduced by half, the space of the fixed door is saved, and the problem that an existing platform screen door cannot be arranged and the net opening degree of the sliding door cannot be multiplied when the size of the fixed door is limited is resolved.
