Description

{DOOR HANDLE FOR FOLDING DOOR}

The present invention relates to a door handle for a folding door used in a folding door, more particularly, a hinge for connecting folding doors is integrally provided to perform a role of a hinge and a handle, The present invention relates to a door handle for a folding door which can open and close a folding door even by force.

Generally, windows (windows) are installed in buildings such as shopping malls, apartments, and buildings for ventilation, lightning, indoor and outdoor ventilation, moving in and out, and people entering and leaving.

The window can be installed on a part of a wall or on a wall of the wall, and can be installed on the wall in accordance with the method of climbing to make it impossible to open or close the window. The door can be opened or closed in the installation direction of the wall, There is a folding type window in which a plurality of individual doors are hinged to each other so as to be rotatable.

Generally, a handle provided on a window is formed by inserting a handle into both grooves on both sides of a window, and a knob is formed with an inner groove, and a flange is formed on the outer periphery. A fixing hole into which the fixing member is inserted is formed.

Such a handle is fixed to the surface of the window frame by fastening the bottom surface of the flange in close contact with the window by means of interference fit in the groove formed in the window and then fastening with the fixing member through the fixing hole formed in the flange.

However, since the above-described conventional handle has to dig a groove separately on both side surfaces of a window and separately attach a handle to each groove, not only the time required for the operation is considerably long, but also when the positions of the two side grooves are not correctly aligned, There is a problem that it is not done. When the groove is not formed in the same shape as the recessed groove of the handle, a space is formed between the groove and the recessed groove, and when the handle is moved due to this, a fruit is generated when the fixing member is fastened, There is a problem that the screw holes are already formed in the folding door so that they are overlapped with each other and are not properly fastened to each other.

Particularly, the folding door is designed so that the doors are sequentially moved and folded by the pushing or pulling of the individual doors in the lateral direction to open or close the doors or windows, or by pushing or pulling the individual doors forward or backward, Doors are folded to open or close the entrance or window.

Therefore, since the door is provided to move the individual door, the door is prevented from being fully folded due to the interference caused by the door handle in the folding process of the individual doors. .

As described above, if the individual doors can not be completely folded together, the open space is not only reduced but also not suitable for appearance. Therefore, there is a need to develop a door handle for a folding door which can sufficiently fold individual doors.

Korean Registered Utility Model No. 20-0448040 (Notice of Mar. 10, 2010) Korean Utility Model Registration No. 20-0257626 (published on December 24, 2001) Korean Patent Publication No. 10-2010-0111464 (published on October 15, 2010)

Therefore, it is an object of the present invention to omit the use of hinges, which are indispensably required for installing a folding door, and to minimize the force used to open and close the folding door when the handle is fixed to the folding door To provide a door handle for a folding door.

Since the handle of the folding door according to the present invention is disposed in a direction in which the folding door is folded, neighboring folding doors can be brought into close contact with each other as much as possible, so that a wide open space can be secured. In other words, the general folding door acts as a stumbling block to obstruct the close contact of the individual doors when the door is installed on the individual door so that the individual door and the individual door closely contact each other. However, The door is disposed at the position of the hinge connecting between the individual doors, and the handle portion is positioned in the direction in which the individual doors are folded, so that the close contact of the individual doors is not hindered.

Further, according to the present invention, when an external force acting on the handle portion is released after individual doors are sequentially moved and folded by the operation of pushing or pulling the handle portion in the lateral direction so that the doorway or the window is opened or closed, The handle can be used at any time because it pivots to maintain the forward position of the door.

In addition, the present invention can partially omit the use of hinges, which are indispensable for installing a folding door, and can be disposed at a position of a hinge to easily open and close the folding door even with a small force.

Further, the present invention can prevent the occurrence of safety accidents such as the user's hand being caught between the individual door and the individual door, because the user uses the handle without pushing or pulling the individual door and the individual door by hand.
