The present invention relates to a hanger door in which an upper roller is mounted on an upper rail in a multi-stage sliding door that is opened and closed by using a roller and a rail.

In particular, the present invention relates to a multi-stage sliding hanger door in which a pair of adjacent door panels are supported in a balanced state by upper rails symmetrically arranged on both sides of the upper structure, thereby increasing balance and stability of each door panel and improving durability. .

Generally, doors are divided into sliding type and sliding type according to the opening and closing method. The sliding type has a disadvantage that the door width is relatively large compared to the sliding type, which takes up a lot of space for installation and adversely affects safety and privacy, but the sliding type does not require a separate space when opening or closing the door. Therefore, it has the advantage that it can be used even in a space where the opening door is not allowed.

The sliding door is a method of opening and closing the door using a rail and a roller among sliding doors, and a door structure in which the door panel is supported by the upper rail because the upper roller is mounted on the upper rail among the sliding doors is called a hanger door. .

The hanger door is a structure in which part of the load of the door panel is caught on the upper rail, and the upper part of the upper roller is in contact with the rail. do.

1 is a side cross-sectional view of a conventional general multi-stage sliding hanger door. Referring to this, a roller (w) is provided on each door panel (p), and each door panel (p) is provided on an upper portion of the frame (f). Many rails r for the rollers w) are provided. Such a hanger door has a structure in which each door panel p is supported by one rail r through a roller w.

Hanger door as shown in Figure 1 is a structure that requires a large space on the top of the frame. That is, as shown in Figure 1, the rail (r) is installed on the side wall of the frame, the rail for the second door panel should be installed at a position higher than the rail for the first door panel, not shown, but the third door The rails for the panels shall be installed at a higher position than the rails for the second door panel. As the number of door panels increases, the upper part of the frame should be higher.

In addition, the hanger door as shown in Figure 1 is poor in balance and stability and durability of each door panel. One side of each rail r is fixed to the side wall of the frame f, and the other side is loaded with a door panel p. When the door panel of such a structure is large in size and heavy, not only does the rail r have a considerable force, but also the door panel p is inclined to one side during opening and closing. This is especially true when the door panels are exposed to the outside and affected by wind, such as evacuation tunnels in tunnels.

Thus, the pair of door panels need to be balanced by the symmetrical positions and supported by the upper rail. Such a structure is disclosed in Korean Patent Laid-Open Publication No. 2001-36191, "Pocket Frame of Sliding Door."

However, the patent discloses that the roller has two wheels, and the rail surrounds the roller, as shown in FIG. Such a structure is generally used in curtains and the like. When the object supported by the roller is light as curtains, it is efficient, but when it is heavy as door panels, opening and closing is inefficient. In addition, in the event of a roller failure, the roller and the door panel attached to it must be completely removed from the rail for maintenance.

The present invention has been made to solve the above-mentioned conventional problems, a pair of adjacent door panels are symmetrically arranged and supported in an upper structure provided with a rail, the sliding hanger with excellent balance, stability and durability To provide a door.

In addition, it is an object of the present invention to provide a hanger door in which all door panels are linked and opened according to opening and closing of the first door panel.

Multi-stage sliding hanger door of the present invention for achieving the above object is a frame; An upper structure arranged on the frame and including a central support member, a horizontal member protruding symmetrically on both sides of the support member, and an upper rail positioned on the horizontal member; A plurality of roller sets mounted on a rail of the upper structure and having a plurality of upper rollers assembled; It comprises a; a plurality of door panels having one set of the roller.

And lower portion of the frame is provided with a lower rail, each door panel is characterized in that it is provided with a lower roller to move along the lower rail,

Unlike the illustrated door structure, the door may be modified in various opening and closing forms and the number of panels. For example, it may be deformed in the form of a double door, or in a form in which a fixed door panel and a moving door panel are accommodated in a wall.

The upper structure 30 is arranged and fixed to the upper body 3 of the frame (F), the two upper rails (33A, 33B) horizontal members 32A, 32B protruding symmetrically on both sides of the central support member 31 ) Is formed. As described above, the door panels P1 / P2 and P3 / P4 are supported by the upper rails 33A and 33B on both sides of the central support member 31, so that the upper structure 30 is balanced without being pulled to one side. Under load. Therefore, the upper structure 30 is uniformly received on both sides despite the load by the door panels (P1 / P2, P3 / P4), so that deformation such as bending in one direction is prevented for a long time. In addition, since the deformation is prevented as described above, the opening and closing of the door panel is also stably made in a balanced state for a long time.

One upper structure 30 is equipped with two door panels (P1 / P2), if the total number of the door panel will be mounted to the number of the upper structure corresponding to the door panel pair, the odd door panel N The door panel located on the opposite side of the first door panel may be used as a fixed panel.
