Description

Insulated window frame with improved insulation by using composite materials

The present invention relates to an insulated window frame, and more particularly, to an insulated window frame using a composite material in which a synthetic resin material is inserted and combined between the metal materials on both sides to significantly improve the thermal insulation of the window frame. will be.

Since most of the conventional window frames are made of aluminum, especially in winter, when there is a large temperature difference between indoors and outdoors, condensation occurs on the frame and partially corrodes, or when water accumulates in the window frame, it freezes, or water runs down the wall. There was a problem in that the aesthetics and durability of the frame were deteriorated, and eventually the frame had to be replaced early. To solve these problems, double-glazed windows have appeared in which windows are installed outside and inside at regular intervals to improve sound insulation and insulation. However, there is a problem in that the insulating function is inferior due to the high thermal conductivity due to the characteristics of the metal material.

In order to solve the problems caused by these materials, a technique to prevent dew condensation by using a frame made of synthetic resin (PVC) material as much as possible, such as Utility Model Registration No. 149614 "Synthetic resin prefabricated windows", has emerged. . However, PVC windows made of synthetic resin have the advantage of compensating for the defects of aluminum, but have very low strength compared to aluminum windows and require a separate finishing treatment due to uniform color.

In order to compensate for the defects of aluminum windows and synthetic resin (PVC) windows as described above, aluminum and synthetic resin frames are installed on the outside and inside, as in Patent Registration No. A technique of placing each and combining them into one frame, or a technique of inserting a metal frame inside a synthetic resin frame, such as Patent Registration No. 946306 "Insulation composite window", has emerged.

In addition, as in Patent Registration No. 1959813 "Composite Insulation Window of Miseogi Chang", a frame in which metal frames are arranged on both sides and an insulation frame made of synthetic resin is inserted between the metal materials to be integrated into one frame appeared. I have the same problem.

First, since it is a structure in which fitting projections and fitting grooves are formed on the inner upper side of each metal frame disposed on both sides, and an insulation frame of synthetic resin material is inserted between fitting grooves formed in each metal frame, and combined, between the metal frames on both sides by the heat insulation frame Although it is possible to block the conduction heat transmitted to There is a problem in that the thermal insulation of the

Second, since the metal frame disposed on both sides and the insulation frame inserted therebetween are combined by the knurling method, a separate automatic processing machine is required to combine the metal frame and the synthetic resin insulation frame by the knurling method, Because it has to go through the knurling process, it takes unnecessary manpower and time, and since the frame once combined with the knurling method cannot be separated, a part of the frame is damaged and there is a problem that the entire frame must be replaced when parts are to be replaced or repaired.

Third, the corner brackets are inserted and coupled between the insertion grooves respectively formed on the inner sides of the lower ends of both sides of the metal frame. If the thickness of the glass changes, the spaced distance between the metal materials and the width of the corner brackets must be different, so they are combined by a knurling method. Since the metal frame and synthetic resin insulation frame cannot be separated once they are combined, the thickness of the glass is different when inserting double glazing and when inserting triple glazing. There is a problem that it cannot.

Fourth, the corner bracket is inserted into the corner of the window frame, that is, the corner where the horizontal frame and the vertical frame meet, and fixed hardware such as bolts are fastened in the corner bracket. Since there is no means to hold the window for a long period of time, not only the bolts may corrode, but also the fastening may become loose, so the coupling force is weakened. there is

Fifth, the corner brackets must be fastened to the corners located at the upper and lower portions of the window frame, respectively. The corner brackets fastened to the lower corners of the window frame must be coupled to the sliding doors on the rail, and the corners fastened to the upper corners. Since the bracket must have a structure without a door part, there is a significant difference in the structure of the corner bracket depending on the presence or absence of the door part due to the structure for fixing the door part, so there is no compatibility. In addition, there is a problem that the fastening must be done with care when fastening.

The present invention has been devised to solve the above problems, and an object of the present invention is to arrange a thermal insulation frame between metal frames disposed on both sides and combine them in a one-touch method to provide excellent bonding properties as well as thermal insulation properties. In order to provide an insulated window frame with improved thermal insulation by using a composite material that can be used by replacing only the metal frame disposed on both sides while using the insulating frame as it is when the thickness of the glass is different.

Another object of the present invention is to form means for coupling the corner brackets at both lower and upper inner sides of the insulating frame, so that it is easy to couple the corner brackets to the insulating frame, and to be fastened to the upper and lower corners of the window frame. This is to provide an insulated window frame with improved insulation using a composite material, which is easy and convenient to assemble the window frame by making the corner brackets compatible with each other.

The insulated window frame with improved thermal insulation by using the composite material according to the present invention is assembled by arranging a metal frame on the indoor side and the outdoor side, respectively, inserting a synthetic resin insulation frame between the metal frames, and combining them. A pair of first fastening parts are formed to protrude inward from the upper part and the lower part of the plate-shaped metal plate part, and a gap between the pair of first fastening parts to maintain a gap with the insulating frame a metal frame configured by protruding retaining protrusions; It is made of synthetic resin material and the cross section is formed in a '□' shape so that a bracket insertion space is formed inside, and the central part of the lower part is open, and the upper part is open on both sides of the open central part of the lower part.

It is formed in a 'C' shape, and is fitted and coupled to the bracket insertion space formed inside the insulating frame, and insertion protrusions are formed at both ends of the open side in the 'C' shape, so that the insertion protrusions are inserted into the insulating frame. It is configured to include a corner bracket that is installed while being coupled to the formed recess, and the first fastening part and the second fastening part are respectively formed in the metal frame and the insulating frame in corresponding shapes to be fastened to each other, so that the metal frame is connected to the insulating frame. It is characterized in that the window frame is coupled in a one-touch method that is pressed and coupled to the side.

Preferably, the horizontal part of the corner bracket is further provided with a roller part so that the sliding window can be opened and closed while sliding on the rail, and the roller part includes a roller that rotates and slides on the rail, and a roller that fixes the position of the roller It is configured with a fixing bracket, and is installed by being inserted into the 'C' shape of the corner bracket.

As it is fastened with the piece, the roller part is fixed.

Preferably, each side of the '□' shape in the heat insulation frame is formed as a double wall having a hollow portion, and a partition wall dividing the plurality of spaces is formed inside the hollow portion.

Preferably, guide projections protruding inward are formed on the inner surface of the upper portion forming the ceiling in the '□' shape constituting the heat insulation frame, and the outer surface of the upper portion forming the ceiling in the 'C' shape of the corner bracket. A guide projection insertion groove of a corresponding concave shape is formed so that the guide projection can be fitted, so that the guide projection insertion groove of the corner bracket and the pair of insertion projections are formed in the guide projection and a pair of recesses, respectively, on the insulating frame. As they are matched and combined, the corner bracket is installed in the bracket insertion space of the insulation frame.

The insulating window frame according to the present invention has a structure in which an insulating frame made of synthetic resin is disposed between metal frames disposed on both sides, and a shape corresponding to each other is formed in each frame, so that the metal frame is pressed toward the insulating frame in a one-touch method. castle is excellent In addition, since there is a structure in which a gap maintaining protrusion is formed to maintain a certain distance from the insulating frame in the inner direction of the metal frame, if the thickness of the glass inserted into the window frame is different, the metal frame disposed on both sides while using the insulating frame as it is It is very economical because the window frame can be used as it is by replacing it with a frame with different heights of retaining protrusions.

In addition, since the insulation frame is a frame formed from the upper part to the lower part where the glass is inserted in the metal frame, when the insulation frame and the metal frame are combined, the metal frames disposed on both sides are spaced apart from each other to block the conductive heat transferred between the metal materials. In addition, since the insulation frame is positioned in the entire space formed between the metal frames arranged spaced apart, no empty space is formed between the metal frames, so it is possible to block the heat transmitted by convection phenomenon as well as improve the strength and significantly improve the insulation can do it

In addition, since the means for coupling the corner brackets are respectively formed on both lower and upper inner sides of the insulation frame, it is very easy to combine the corner brackets inserted into the insulation frame, and the upper and lower corners of the window frame Since the structure of the corner brackets fastened to the frame is the same, the corner brackets are compatible with each other, making it very easy and convenient to assemble the window frame.

Means for coupling the corner brackets are provided on both sides of the inner upper and lower sides, so that the combination of the corner brackets is made accurate and easy. By making it compatible, it is convenient to assemble the window frame.

In the insulating window frame 10 according to the present invention, metal frames 11 and 11' are disposed on the indoor side and the outdoor side, respectively, and the insulating frame 12 made of synthetic resin is inserted between the both sides of the metal frame 11 and 11'. It is a window frame of Miseogi Chang assembled by combining them together. The window frame 10 is manufactured by combining the horizontal frame 101 and the vertical frame 102 by inserting corner brackets 20 into each corner.

The metal frames 11 and 11' are positioned so that the plate-shaped metal plate part 111 faces outward, and a pair of first fastenings in the upper part and the lower part in the plate part 111 in the inward direction. The portion 112 is formed to protrude, and between the pair of first fastening portions 112, a gap maintaining protrusion 113 for maintaining a predetermined distance from the heat insulating frame 12 is formed to protrude. The first fastening part 112 formed at the lower end of the plate part 111 is bent vertically in the inner direction (the 'inside' refers to the side where the heat insulating plate is located, and is the same in this specification) of the plate part 111. This is a space in which the glass is inserted above the first fastening part 112 formed in the upper part of the plate part 111 .

The insulating frame 12 is made of a synthetic resin material and serves to connect and couple the metal frames 11 and 11' respectively disposed on the indoor and outdoor sides, as well as conduction and It blocks the heat transferred by convection. Insulation frame 12 is located from the upper part to the lower part, which is the part where the first fastening part 112 is formed in the remaining part except for the space in which the glass is inserted, that is, the metal frame 11, 11'. 11'), since there is no space where they directly face each other, heat transfer due to convection between the metal frames 11 and 11' is blocked, and the strength of the frame is also reinforced (refer to FIG. 2a).

The insulating frame 12 is provided with both side plates 121, an upper plate 122, and a lower plate (reference numeral not specified) so that a cross-section is formed in a '□' shape, and a bracket insertion space 124 is formed therein. , '□'-shaped lower plate has an open central portion, and recessed portions 125 with an upper open side are formed on both sides of the lower open central portion, respectively, and the '□'-shaped upper surface and At both ends of the lower surface, that is, the second fastening portion 123 is formed on both ends of the upper plate 122 and the lower plate (see FIG. 2B ).

In the heat insulation frame 12, the side plate 121, the upper plate 122, and the lower plate are formed as a double wall with a hollow portion formed therein to improve thermal insulation, and a partition wall dividing the hollow portion into a plurality of spaces is provided in the hollow portion. It is preferable that it is formed.

A first fastening part 112 and a second fastening part 123 are respectively formed in the metal frame 11 and 11' and the heat insulating frame 12 to have a corresponding shape, such as a concave-convex shape, so that they can be fastened to each other. The frames 11 and 11' are combined in a one-touch method in which the frames 11 and 11' are pressed toward the heat insulating frame 12, and the window frame 10 is assembled.

Since it is a structure combined with a one-touch method, it is easy to combine and separate the frame, so the bonding property is excellent. ') is separated from the insulation frame 12 and replaced. In addition, since the gap maintaining protrusions 113 and 113 ′ for maintaining a certain distance with the insulating frame are formed in the inner direction of the metal frame, when the protruding height of the gap maintaining protrusions 113 and 113 ′ is different, the metallic frame The width of the space where the glass is sandwiched between (11, 11') is changed. Therefore, when the thickness of the glass inserted into the window is different, for example, when replacing the double glass with the triple glass, the insulating frame 12 is used as it is and the gap maintaining protrusion in the metal frames 11 and 11' disposed on both sides. It is very economical because the window frame can be used as it is by replacing only the frame formed with different heights (see FIG. 4).
