Description

Folding door

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding door, and more particularly, to a folding door capable of opening and closing a door in both directions so as to efficiently utilize space.

2. Description of the Related Art Generally, a folding door is a door that is folded and unfolded while a plurality of doors are connected to each other with a structure similar to a folding screen. Recently, the folding door has been applied to a partition partitioning a balcony or an interior wall or a room. In conventional folding doors, the sliding doors are installed and folded on the upper frame in which the upper rail is formed. That is, the load of the sliding doors is supported by the upper frame. Therefore, in the conventional folding door, the upper frame supporting the load of the sliding doors is bent without being able to withstand the load.

In order to solve such a problem, as shown in FIG. 1, Korean Patent Registration No. 10-1540218 discloses a door unit 200 comprising a plurality of doors; And a frame enclosing at least one of upper and lower portions of the door connected to the connection unit 230; (250) which is provided at a side of the door which is not connected to the connection part (230) and which is connected to and fixed to the wall of the space where the door frame or the door is installed; And a driver 240 installed in at least one of upper and lower portions of the door without the fixing part 250 of the door so that the door can be rotated about the vertical direction in the vertical direction; And a door circular magnet 212 is provided on the first door 210 of the door unit 200 at a distance of 60 to 90 mm from the upper side and the lower side of the left side of the first door 210, The first door 210 and the left side frame 320 abut on the left side frame 320 of the door frame 300 at a position corresponding to the door circle magnet 212 on the side where the first door 210 and the left side frame 320 abut, And a door frame circular magnet 322 having a polarity opposite to that of the magnet 212 is provided so that when the door is closed, the magnets are attracted to each other by the attraction force of each other and the lower part of the door part 200, The door unit 300 is provided with mohair in the direction in which the door is opened in the right and left directions and the direction in which the guide rail 312 is located in the upper and lower sides of the door frame unit 300, A slide part (241) for moving in the lateral direction along the rail (312); A rotation part 242 coupled to a lower end of the slide part 241 and allowing the first door 210 to rotate clockwise and counterclockwise; And the slide part 241 can be separated from and coupled to the rotation part 242. This is because when the door is opened or closed, clothes or fingers There is a problem that an accident can occur and a noise can be generated.

In order to solve the problems described above, it is an object of the present invention to provide a folding door capable of efficiently using a door without restriction of a space when the door is opened and closing, do.

There is provided a folding door comprising a first door provided with a hand and a main locking device, a second door provided with a fixed-portion bidirectional hinge, and a second door coupled to the upper and lower ends of the first door and the second door, Directional hinge and a connecting portion that is coupled to the center between the first door and the second door.

According to another aspect of the present invention, the connection portion bi-directional hinge includes a hinge release preventing portion at one end thereof, the connection portion includes a diffraction portion folded in both directions, and a pair of hinge portions provided on both sides of the diffraction portion, And a coupling plate coupled to the first coupling portion and the second coupling portion and having a plate hole.

According to another aspect of the present invention, a urethane foam is provided between the connecting portion bidirectional hinge and the connecting portion, and the urethane foam is provided with protrusion coupling holes at both ends thereof. The hinge protrusion is provided at the connection portion bidirectional hinge, To the subprojection.

As described above, the folding door according to the present invention can open and close the door in both the interior and the exterior directions, so that it can be utilized effectively without any limit of space and the urethane foam is attached to the connection part, . In addition, the plate holes can minimize the interference of the door that occurs when the elliptical connection is folded
