Description

Door linkage

The present invention relates to a connecting device for installing the door to the door frame, and more specifically, the connection device for connecting the door made of aluminum or steel to the door frame is embedded in the upper and lower parts of the door frame to facilitate the installation of the door and to level the door. A door connection device that can be easily adjusted.

Today, due to changes in the residential environment and changes in the shape of the house, houses such as townhouses, multi-family houses and apartments have been widely used. In the case of these houses, the front door is used as a separation from the outside and a role of a doorway. In addition, the user demands not only a security function but also an aesthetic appearance for such a front door, and recently, an aluminum front door with a decoration is widely used as a front door of a multi-family house.

These front doors generally have a structure in which the doors are installed in aluminum door frames, and hinges (also called 'hinge') are most commonly used as a means of connecting the doors to the door frames.

Here, the installation structure of the door using the hinge of the prior art will be briefly described, and the door frame is installed at the position where the front door is to be installed, and the door corresponding to the door frame is constructed by a hinge. That is, the door is mounted on the door frame by fixing the hinge with a screw on one side portion to which the door of the door frame is attached, and fixing the door to the door using the screw on the other side of the hinge.

However, when mounting the door to the door frame using the hinge as described above, it is difficult to level the door and also difficult to install. That is, when three hinges are fixed to one side of the door, and then the other side of the hinge is fixed to the door frame, it is very difficult to fix the screws by leveling the door.

In addition, a phenomenon in which the door's center of gravity does not prevent the phenomenon of being pulled to one side is caused to be mounted or tilted in one direction by the center of gravity of the door after mounting. If the door is inclined to one side, the screw installed on the hinge should be removed and re-installed to re-level the door again. However, at this time, the part where the screw was once fixed is difficult to install the door again because of the hole of the screw, and the screw marks remain to damage the aesthetics. In addition, in the case of doors and door frames made of metal such as aluminum, when the door is installed by using a hinge, a hole in the door and the door frame where the screw is to be fixed in advance by using a tool of drills should be used. That is, the hinge is attached to the door and the door frame to be attached to the predetermined position of the door and the door in advance to fix the hinge and the door and the door frame has a disadvantage that the door installation work is difficult.

Accordingly, an object of the present invention is to provide a door connection device for overcoming the disadvantage of the difficulty of installing the door horizontally when installing the door to the door frame to facilitate the installation and horizontal adjustment of the door.
