Frame corner piece assembly structure that can stably maintain the combined state without shaking}

The present invention relates to a frame corner piece assembly structure that can stably maintain the coupling state of the corners of various window frames or door frame frames made of a metal material without shaking. In joining the corners where the vertical frames meet through the corner clamping operation, the structure of the corner piece fitted inside the corner is improved so that the horizontal frame and the vertical frame are firmly combined with the corner piece without shaking. It relates to a frame corner piece assembly structure capable of stably maintaining a new type of combined state that can maintain a solid joint state of the corner piece stably for a long period of time without shaking.

In general, in buildings constructed for the purpose of allowing people to enter and live or engage in specific activities, windows are installed to ventilate the indoor space. It also has a purpose for

In addition, it is common for windows to be installed with insect screens or insect screens to prevent insects from penetrating into the room when they are opened. may also be installed.

In addition, as for the window frame or the door frame through which a person enters as described above, each corner of the upper, lower, left, and right door frame frames made of a rectangular parallelepiped is cut at 45°, and then each corner is fixed by fastening screws or a corner piece inside the frame. A window frame or a door frame is formed by combining the frame and corner piece through bolting or corner clamping work on the outer peripheral surface of the frame where it is fitted.

However, the method of connecting the corners of a window frame or door frame as described above has a problem that the assembly state of each corner part is slightly shifted or pushed when fixing the corner part, and accordingly, when the door frame is assembled and construction is completed, after the door and door leaf assembly There was a problem with the lack of mutual confidentiality.

In addition, a problem that the frame shakes frequently occurs because the connection part between the corner piece and the frame is easily deformed. In order to solve this problem, various types of corner pieces have recently been studied.

Patent Registration No. 10-1420367 (registration date: July 10, 2014) as a conventionally known technology for corner pieces as described above, a method for fixing a corner of a window frame and a corner piece used therefor, a vertical bar and a horizontal bar are formed at right angles, In the corner piece in which at least one vertical locking groove is formed on the outer surface of the vertical bar and at least one horizontal locking groove is formed on the outer surface of the horizontal bar, a vertical locking protrusion piece is formed in the vertical locking groove of the vertical bar, The locking stone piece is configured such that a vertical cut-out bent part is bent between the vertical locking protrusions to form a locking space between the vertical locking protrusion and the vertical locking protrusion, and a horizontal locking stone piece is formed in the horizontal locking groove of the horizontal bar. The horizontal incision bent portion is bent between the horizontal locking protrusions, and a locking space is formed between the horizontal locking protrusions and the horizontal locking projections. When fixing the vertical frame in such a way that the vertical bending locking piece is caught in the vertical locking groove while forming, the vertical bending hooking piece is inserted while pressing the vertical locking protrusion and is caught between the vertical locking projections so as not to move in the front and rear direction, and the horizontal frame is placed on the horizontal bar When inserting, cutting and bending a part of the horizontal frame to form a horizontal bending locking piece and fixing the horizontal frame in such a way that the horizontal bending hooking piece is caught in the horizontal locking groove, the horizontal bending hooking piece is inserted while pressing the horizontal stopping protrusion It is characterized in that it is configured not to move in the forward and backward directions.

On the other hand, the patent registration No. 10-2341460 (registration date: December 16, 2021) pre-registered by the present applicant is a metal door frame frame right angle corner assembly device, the metal door frame frame right angle corner assembly device has a 'L' shape A right-angled frame on which the metal door frame is disposed, a gripping tool disposed close to the edge of the right-angled frame and holding the edge of the metal door frame disposed on the right-angled frame so that the edge of the right-angled frame does not move; and a side press-fitting tool for press-fitting the side surface of the metal door frame frame disposed on the side of the right-angled frame, wherein the forward/backward operation part of the holding tool is fixed to the front side and the working distance is limited at the rear It consists of a movable shaft on which the sphere is fixed and a pneumatic cylinder body for moving the movable shaft forward and backward, and the movable limiting distance of the movable shaft is limited by changing the length of the working distance limiting sphere disposed at the rear, and the side press-fitting tool is , a press-fitting part for pressing the side of the rectangular frame to be in close contact with the side of the metal door frame frame, and formed on one side of the press-adhesive part to press-fit the side of the metal doorframe frame in a state in close contact with the press-adhesive part to deform and fix it It characterized in that it comprises a press-fitting deformation part, and a press-fitting forward and backward operation part for moving the press-fitting deformation part and the press-fitting part back and forth in the direction of the side surface of the metal door frame frame.

However, the conventional corner piece for connecting the window or door frame including the prior art uses a bolting coupling method using bolts, screws, pieces, etc. or corner clamping to connect the frame and the corner piece. ) because the coupling method is applied, in the case of bolting coupling, there is a problem in that the aesthetics is deteriorated along with the productivity decrease due to the bolting coupling process such as the process of forming holes in the frame and corner pieces. When a window frame or door frame is used, the connection part between the frame and the corner piece of the window frame or door frame becomes loose and the window frame or door frame frame shakes. There was a problem that the connection part between the frame and the corner piece of the frame was loosened and the problem that the window frame or the door frame frame was shaken repeatedly continued.

Registered Patent Publication No. 10-1420367 (Registration date: July 10, 2014) "Corner fixing method of window frame and corner piece used therefor" Registered Patent Publication No. 10-1157086 (Registration Date: June 11, 2012) "Assembly Structure of Window Doors with Joints of 45°" Registered Patent Publication No. 10-2341460 (Registration Date: December 16, 2021) "Metal Material Door Frame Right Angle Corner Assembly Device"
