Description

Window assembly with multiple airtight structure {WINDOWS AND DOORS ASSEMBLY HAVING MULTI-LAYERED SEALING STRUCTURE}

The present invention relates to a window assembly having a multi-airtight structure, and more particularly, by providing a multi-tight structure in the form of "U" and inverted "C" in the fastening area, the intermediate space among the rails of the door frame or the window frame It relates to a window assembly having a multi-airtight structure that can prevent heat loss due to indoor and outdoor thermal bridges due to conduction, convection, and radiation through conduction, convection and radiation.

Windows and doors refer to windows and doors, which are used to separate indoor and outdoor areas to block the wind while allowing sunlight to enter the room or to ventilate the room.

The structure of a window is basically composed of a window frame (or door frame) that forms the main frame and a window frame (or door leaf) mounted therein.

Windows and doors are classified according to the way they are opened, such as opening type, sliding type, or fixed type.

In addition, depending on the number of window frames (or door frames) installed on one window frame (or door frame), it is divided into single window, double window, and triple window. Insulation and sound insulation by injecting an inert gas into the space in between or by forming a space layer to increase the insulation and sound insulation performance of double-layered glass and three single-pane glasses, respectively, and injecting an inert gas into the space between them or forming a space layer It is sometimes classified as triple (or triple layer) glass with improved performance.

In addition to this, various classifications exist.

In addition, the material constituting the window frame (door frame) and the window frame (door leaf) has been used a lot in the past, but recently aluminum and polyvinyl chloride (PVC, hereinafter referred to as 'synthetic resin') materials are widely used. Aluminum does not cause decay, deformation, or oxidation like wood, so it is usually installed on verandas or buildings with gorgeous exteriors.

However, due to its high thermal conductivity, aluminum has structural disadvantages in that the insulation effect is poor, and when used for a long period of time due to thermal deformation, there is a gap in the assembly area, which reduces the sound insulation and insulation effect.

On the other hand, synthetic resin is superior to aluminum in thermal insulation effect, so in most cases, it is installed in the form of double-glazed windows at the boundary of parts in contact with the outside of apartments, houses, schools, etc.

Meanwhile, since July 1, 2012, the energy efficiency rating system, which has been applied to home appliances and automobiles, has been implemented for windows and doors. is becoming

Invented from the above point of view, there may be mentioned "rail windbreak device for sliding windows" (hereinafter referred to as prior art) of Korean Patent Registration No. 10-1722060.

The prior art relates to a rail windbreak device for sliding windows positioned between a rail and a rail of a window frame, and for maintaining airtightness by blocking a gap between the bottom surface of a pair of first and second windows and the bottom of the window frame, the rail and a windbreak member comprising a lower plate fitted between the rails and installed on the bottom of the window frame, and a pair of close contact pieces formed symmetrically by protruding outward on both sides of the lower plate; and the first and second windows are fixed to the first and second windows, and in a state in which the first and second windows are closed, the close contact piece of the windbreak member is pressed in close contact with the bottom surfaces of the first and second windows, and the first and second windows are closed. When moving in the opening direction, it is spaced apart from the contact piece and includes a pressing member for releasing the pressure of the contact piece.

However, considering that heat loss and inflow of dust, wind, or foreign substances occur not only through the lower side of the window frame, but also through the space between the window frame and the adjacent window frame, the prior art is concerned with heat loss and It can be said that the invention has a clear limit to prevent deterioration of airtight performance.

In addition, in the existing double-glazed window structure, an assembly of a structure in which a windbreak frame is mounted only on overlapping windows or doors can be applied. There were also concerns.

And, by installing the airtight insulation unit 300 according to the present invention to the inner window or door 120 and the outer window or door 210, it is possible to provide a highly reliable product by increasing the installation freedom according to the installation environment. have special advantages.

And, the airtight insulation unit 300 according to the present invention, as constituting the main frame 310, one side of both sides of the inner window or door leaf 120, or one side of both sides of the outer window or door leaf 210 The main core piece 313 mounted on the, extending from the edge of the main core piece 313 to face the front or rear of the inner window or door 120 or facing the front or rear of the outer window or door 210 By including the main reinforcing pieces 311 and 312 and a brush 314 formed on the outer surface of the main reinforcing pieces 311 and 312 to block the inflow of foreign substances, dust and wind from the inside and outside the brush 314 made of a plurality of mohair, It has the advantage of being able to simultaneously implement insulation and airtight performance with a relatively simple structure.

In addition, the airtight insulation unit 300 according to the present invention constitutes the main reinforcement pieces 311 and 312 , and extends from one edge of the main core piece 313 to the front or rear surface of the inner window or door 120 . The first main reinforcing piece 311 and the main reinforcing pieces 311 and 312 facing or facing the front or rear of the outer window or door 210, which constitutes the main reinforcing pieces 311 and 312, from the other edge of the main core piece 313 It extends and includes a second main reinforcing piece 312 facing the front or rear of the outer window or door 210 or facing the front or rear of the inner window or door 120, and the brush 314 includes the first main By making it to be formed on some or all of the outer surface of the reinforcing piece 311 and the second main reinforcing piece 312, the thermal insulation performance of reliably blocking the passage of heat inside and out in the process of opening and closing a window or door can be further strengthened. has the advantage of being able to

In addition, the airtight insulation unit 300 according to the present invention, from the inner surface of the first main reinforcing piece 311, the front or rear of the outer window or door 210, or the front or rear of the inner window or door 120 From the inner surface of the first gap maintaining rib 315a and the second main reinforcing piece 312 protruding toward the front or rear of the inner window or door 120 or the front or rear of the outer window or door 210 The protruding second spacing rib 315b, the pair of insertion ribs 316 protruding from the inner surface of the main core piece 313, and the pair of insertion ribs 316 protrude from the outer surface of the distal end of each By further providing a hook piece 316h that is hooked and fixed to the recessed portion 121 formed on both sides of the outer window or door 210 or on both sides of the inner window or door 120, it is possible to maintain structural strength, of course, Since it has an intuitive structure for the operator, it has the advantage of greatly improving the convenience of work in that it can be easily installed on or easily separated from the window or door regardless of skill level.

As described above, the present invention provides a multi-airtight structure in the form of "C" and inverse "C" in the fastening zone, so that the indoor and outdoor thermal bridge phenomenon due to conduction, convection and radiation through the intermediate space among the rails of the door frame or window frame It can be seen that the basic technical idea is to provide a window assembly having a multi-airtight structure that can prevent heat loss.

And, within the scope of the basic technical spirit of the present invention, many other modifications and applications are also possible for those of ordinary skill in the art.
