In addition, there is no accident that a finger is caught between the leaves of the door, and widening of a space between the leaves of the door is minimized so that the door has excellent heat and sound insulation effects. According to the present invention, the door capable of being slid and partially folded includes: a pair of hinge frames (100, 100′) allowing upper and lower rotation devices to be fastened to the upper and lower portions thereof, respectively; a vertical frame (300) fastened to both sides of the hinge frames, wherein fastening pieces of the upper and lower rotation devices are fastened to the upper and lower portions thereof; and the upper and lower rotation devices (500, 700) fastened to the upper and lower portions of the hinge frames to rotate the door (D).

Description

Sliding and folding doors < RTI ID = 0.0 >

More particularly, the present invention relates to a door that can be opened and closed in both forward and backward directions, and can be opened by a full width of a door frame, and two doors can be opened at the same angle So that the closing and opening operation can be performed reliably, the accident that the fingers or the like are caught between the doors does not occur, the gap between the doors is minimized, and the sliding / It is about the door that can fold part.

Generally, a folding door having a structure in which a plurality of doors are hinged is not structurally robust but has an advantage of maximizing the opening width as compared with a general sliding door or a non-sliding door.

Such a folding door has an advantage that it can overcome the drawback that opening and closing of the door is inconvenient when an obstacle exists in the direction of opening the general sliding door because the turning radius is small when opening and closing.

Patent Document 1 discloses a folding sliding door in which a first door and a second door are connected by a hinge and the end of the first door is rotatably fixed to the wall. In the case of the folding sliding door having such a structure, When the second door with the handle is opened and closed by hand, the second door is first opened while being rotated by the hinge engaging part about the axis, and the first door is opened with the opening of the second door The opening force applied to the second door is not openly linked to the operation but is opened by reacting differently from the opening state of the second door depending on the direction of the operation of the strength or the force so that when the folding door is opened or closed , It is not easy to make a straight line between the second door with the handle at the time of closing and the first door so that the door is left in a state that it is not properly closed, Due to consumer demand and the improvement of these problems.

Patent Documents 2 to 4 disclose such folding sliding doors, but the same common problems as in Patent Document 1 still remain.
