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 it is difficult to prevent the shaking even if the door is fixed by the magnet.

Korean Registered Patent No. 10-1540218 (July 27, 2015) Korean Patent Publication No. 10-2014-0033901 (Apr. 19, 2014)

In order to solve the above-mentioned problems, the present invention provides a folding door that can be efficiently used without restriction of a space when a door is opened and a urethane foam is provided at a connecting portion to prevent pinching and wobbling The purpose.

A second door having a first door having a handle, a main locking device and a first exterior finish, a fixed-body bidirectional hinge and a second exterior finish, a first door having a first door and a second door, A pair of hinges connected to the upper and lower ends of the door, and a diffracting portion folded in both directions. The hinges are coupled to the first and second couplings provided on both sides of the first door and the second door, And a connecting frame connected to the center between the first door and the second door, and a connection frame rotatably mounted on the front or rear surface of the first exterior finisher, And a case frame engaging portion to which the above-mentioned frame is joined and separated.

In another aspect of the present invention, the connection portion bi-directional hinge is provided at one end with a hinge release prevention portion.

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 hole can minimize the interference of the door that occurs when the elliptical connection portion is folded, and since the locking device is installed at the connection portion, the door can be unstably shaken or the door can be prevented from being opened / have.

FIG. 3 is a front view of the folding door according to the present invention, FIG. 4 is a top view of the folding door according to the present invention, and FIG. 5 is a top view of the folding door BB ' The following is an explanation.

The present invention provides a folding door comprising: a first door (10) having a handle (11), a main locking device (12) and a first exterior finish material (14); a fixed door bidirectional hinge (21) A second door 20 having a first door 20 and a second door 20, and a connecting portion bi-directional hinge 30 connected to the upper and lower ends of the first door 10 and the second door 20; And a first coupling portion 13 provided on both sides of the first door 10 and the second door 20 and a second coupling portion 13 provided on both sides of the diffraction portion 41, A connecting portion 40 formed at the center between the first door 10 and the second door 20 and formed of a connecting plate 43 coupled to the first portion 10 and the second portion 22 and having a plate hole 42; And a case frame 62 on the front or rear surface of the second exterior finish material 23 and the case frame 62 rotatable with respect to the case frame shaft 61 on the front surface or the rear surface of the first external surface finishing material 14, And a locking unit (63) for locking and disengaging the locking unit (63).

At this time, the connecting portion bidirectional hinge 30 and the fixed portion bidirectional hinge 21 are known from Korean Patent Laid-Open Publication No. 10-2014-0033901 as disclosed in Fig. 2 so that the door can be efficiently opened and closed in both directions You can apply a hinge. Various known bi-directional folding hinges can be applied.

The connecting plate 43 may be fixedly coupled to the first door 10 and the second door 20, respectively. In addition, the plate holes 42 can minimize the interference of the doors when the first door 10 and the second door 20 flow to the left and right with the elliptical shape and the connecting portion 40 is folded .

When the case frame 62 is detached from the case frame fitting part 63 and rotated in the counterclockwise direction with respect to the case frame shaft 61 on the connecting part 40, the door can be opened and closed, When the door 62 is coupled to the case frame engaging part 63, the connecting part 40 is fixed by the locking device 60, so that the door is unstably shaken and the door is prevented from being opened or closed by an external force such as wind. have.

And a hinge release preventing portion 31 is provided at one end of the connecting portion bidirectional hinge 30. The hinge release preventing portion 31 prevents the connection portion bi-directional hinge 30 coupled between the first door 10 and the second door 20 from being detached.

Further, the urethane foam 50 is provided between the connecting portion bidirectional hinge 30 and the connecting portion 40.

FIG. 6 is a perspective view of a urethane foam of a folding door according to the present invention, and the construction and the joining method of the urethane foam 50 will be described in detail as follows.

The urethane foam 50 is provided with protrusion defect holes 51 at both ends and has hinge protrusions 32 provided on the connecting part bidirectional hinge 30 and diffraction part protrusions 44 provided on the connecting part 40 . The urethane foam 50 is divided into a lower part on the connecting plate 43 and a lower part. The urethane foam 50 is excellent in elasticity and flexibility, so that there is no danger that the clothes or fingers are caught in the connection portion 40 when the door is opened, thereby preventing a safety accident and also preventing noise. Come back.
