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 that is installed in a window or a veranda door and is opened and closed by hinging a plurality of window doors.

The folding door is installed in a built-in cabinet or a display case and can be opened and closed.

1, the folding door is installed in a state in which the first and second open / close doors D1 and D2 are opened and closed and the first and second open / close doors D1 and D2 are opened / The folding door H is constructed including the hinge G which is provided over several places and is folded.

Three first to third openable and closable doors are hinged to each other by a hinge, and the two side open and close doors are brought into contact with each other by the hand to pull the both openable and closable doors open while being folded.

When completely opened, three open / close doors are folded and overlapped to one side.

However, conventionally, there is a disadvantage in that opening and closing operations can not be performed properly because it is inconvenient to hold the side bar of the opening and closing door by hand.

Meanwhile, in order to facilitate grasping by hand during opening / closing operation, a method of forming a hole in the glass to form a grasping hole has been proposed. However, since the grasping air is blown from the outside through the grasping hole and the internal temperature is lost, There were disadvantages.

FIG. 8 is an exploded perspective view of a folding door according to another embodiment of the present invention. , FIG. 9 is a plan view of a 'handle cover' of a folding door according to another embodiment when the door is closed, and FIG. 10 is a plan view showing a folding door of the folding door according to another embodiment It is a flat section for when it is opened.

1 to 10, the folding door A according to the embodiment includes a door frame 100 composed of an upper frame 120, a lower frame 140 and a side frame 160, And a plurality of window doors 200 coupled to the door 100. Each of the window doors 200 is hinged to the hinge 300 and folded.

The window door 200 is composed of three pieces in the door frame 100. For convenience of classification, it is named as the first window door or the third window door.

Each window door 200 has a rectangular shape in which a horizontal bar 210 and a vertical bar 220 are connected to each other and glass is coupled.

Here, a handle groove 230 is formed in the vertical bar 220 to facilitate gripping.

The vertical bar 220 is an extruded frame, and the handle groove 230 is formed at an engraved center using a machining center.

The handle groove 230 is formed in an elliptical shape having a length enough to insert a plurality of fingers at the same time, and is formed in a substantially vertical direction.

In the illustrated embodiment, only one handle groove 230 is formed. However, the present invention is not limited thereto and a plurality of handle grooves 230 may be formed.

On the other hand, each of the plurality of window doors 200 is formed with a guide slot 202 in a longitudinal direction thereof.

A guide slot 180 is formed in the door frame 100 in the longitudinal direction. Preferably, a guide slot 180 is formed in the upper frame 120 of the door frame 100.

A guide shaft 170 coupled to the guide slot 202 of the window door 200 is formed in the guide slot 180 of the door frame 100.

The guide shaft 170 can be folded and operated on the plurality of the window doors 200 while linearly moving along the guide slots 180 and the guide slots 202. [

When the window door 200 is completely opened, the guide shaft 170 is perpendicular to the door 100 and the guide shaft 170 reaches an intermediate position between the guide elongated hole 180 and the guide elongated hole 202.

According to another embodiment of the present invention, a knob cover 2 hinged to the knob groove 230 to open and close the knob groove 230 may be included to prevent the foreign material from entering the knob groove 230.

The handle cover 2 includes a rotary plate 21 having hinge shafts 22 formed at both ends thereof and the hinge shafts 22 fitted into the knob grooves 230 to be rotationally operated. And an elastic member 26 coupled to the hinge shaft 22 of the rotary plate 21 and exhibiting an elastic restoring force.

The rotating plate 21 is an area that can completely block or partially cover the handle groove 230 and has a hinge shaft 22 formed at the upper and lower ends thereof to press the fitting hole 230 formed on the inner side and the lower side of the handle groove 230, And can be opened or closed while being rotated.

The elastic member 26 is coupled to the hinge shaft 22 to automatically return to the original state when the external force is released after the opening operation, and includes a torsion spring.

The operation of the thus configured embodiment will be described as follows.

The first window door to the third window door are inserted into the door 100 and each window door 200 connects the hinge 300 to the lower end and the upper end of the vertical bar 220.

The positions of the hinges 300 are differently formed so that the three window doors 200 can be folded in a zigzag fashion.

In order to open the window door 200, as shown in FIGS. 4 to 6, the adjacent vertical bars 220 of the two window doors 200 are held while the handle grooves 230 on both sides are held between the thumb and the rest The two window doors 200 can be opened when they are folded and pulled while gripping with the fingers.

Therefore, the user can easily grasp it by using the handle groove 230, and a plurality of the window doors 200 can be opened or closed while keeping the state without grasping the force.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention, It is obvious that the claims fall within the scope of the claims.
