Description

Frame structure for door < RTI ID = 0.0 >

The present invention relates to a door frame structure, and relates to a frame installed in a vertical direction of a door on which a glass is installed.

BACKGROUND OF THE INVENTION [0002] In general, a folding door is widely applied in recent years to a door without a space for fully opening a door installed outside a doorway of a wall, or to allow an entrance to be fully opened to achieve affinity with other surrounding environments.

Such a folding door is provided so as to be slidable along the rails provided on the door frame, as well as hinged to the plurality of individual doors so as to be rotatable with respect to each other.

Accordingly, the doors are sequentially moved and folded by pushing or pulling the individual doors in one direction, thereby opening or closing the door.

However, such a conventional folding door has a structure in which a handle for fixing the door frame is protruded. Therefore, there is a problem that interference due to the knob is generated during the folding process and the folding is not completed.

If the individual doors are not completely folded together, the open space is not only reduced but also is not suitable for appearance.

In addition, in the case of the folding door, the glass is installed inside the door frame, and the frame on which the glass is installed has a disadvantage that the weight is large. There is a problem.

As a prior art for solving the above problems, a "folding door" is disclosed in Japanese Unexamined Patent Application Publication No. 2007-112359 (published on November 23, 2007). The folding door is located between doors. On both left and right sides, A handle frame extending from the handle frame; An annular guide groove formed integrally with the outer end of the plate and coupled to the pivot shaft of the corresponding handle frame is formed at one side A tilt frame formed of a guider having a 90-degree angular opening formed therein; A handle rotatably inserted into an outer side of the center of the handle frame and rotatably coupled to the carrier in an upward and downward direction along an inner surface of the handle frame by pivoting; And upper and lower engaging plates respectively coupled to the carriers and selectively engaging and disengaging the engaging grooves of the door frame by rotation of the handle.

The folding door constructed as described above is constructed by connecting a plurality of doors, and the weight of the door frame and the glass is increased, so that the door can not be easily moved.

Further, in the case of the handle provided between the door frame and the frame, there is a problem in that the weight is added to the door frame because it is installed between the door and the door.
