Description

A Window System for Air Tightness Between the Window,

The present invention relates to a structure for improving the airtightness of a system window, and more particularly, to an air conditioner which improves the airtightness between windows to improve the heat insulation performance by blocking the flow of air circulating between the window frame and the window frame Which is related to the system window.

The windows used for viewing and daylighting of a building have problems due to heat loss at the same time, despite the advantage of the windows themselves. Generally, the heat insulation performance of building windows is 6 ~ 10 times lower than the insulation performance of outer walls, which is a heat - loss vulnerable area. Therefore, researches and efforts are being made to improve the insulation performance of windows.

In particular, research has been carried out to improve the airtightness and thermal insulation of the entire window including the windows and window frames as a so-called 'system window' as a method of enhancing the airtightness and insulation performance of the windows. Accordingly, the window frame material is made of a high- And a gasket having a high airtightness and a high heat insulating performance has been developed by using a gasket which can be fixed to a window frame.

The distribution of air that generates the greatest heat loss in the window structure is largely due to the gap between the horizontal frame of the window frame and the rail installed in the horizontal frame of the window frame and the gap between the vertical frame of the window frame and the vertical frame of the window frame, At the time of closing, the window frame is mainly formed in the gap of the intersection of the vertical frames. Therefore, in order to improve the airtightness performance of the conventional window, the most important point was to maintain the airtightness of the three upper portions, and a fine gap, for example, a space between the rails The air tightness of the perfect window in relation to the phenomenon that the air flows in the direction of the rail through the through hole is a little studied. However, such a small air distribution channel is a task that must be solved in the structure of a modern building window that pursues zero energy.

In addition, in order to apply the airtight structure to the window, a configuration called a "Filling Piece" applied to the window is utilized, which is installed in a sliding window sash (a sash window of a sashimi window) It can be said that it is an accessory for windows to improve the heat insulation and soundproof effect of the window by filling the space. Such a peeling piece is positioned on the surface of the window where the guide rail is formed. When the window is completely closed, the window is placed so that the windows are opposed to each other at the upper and lower ends of the overlapping portions. In this case, since the gap between the overlapping portions of the windows is sufficiently narrow and the overlapping portions are designed to be engaged with each other when the windows are completely closed, soundproofing and heat insulation can be expected to some extent. However, the upper and lower ends of the overlapping portions are inwardly And there is a space between them. This confidentiality tends to be independent of each other, rather than the overall relationship due to the organic relationship between the two, so that efficient means of maintaining the confidentiality of the window can not be provided.

In such a filling piece, Korean Patent No. 10-1336583 discloses " a high airtight structure of a window ".

The present invention can maintain the airtightness of the entire window completely without obstructing the movement of the window, thereby improving the heat insulation performance as well as preventing the heat loss by the convection, and having a high car sound. Tight structure of a window in which performance such as voice is not deteriorated at all.

However, in the case of the above-described structure, the peeling pieces are composed of a plurality of sheets of plates, and thus the windows can be torn as the windows move, and furthermore, as the use year of the windows increases, there is a disadvantage that they are liable to be torn or laid down. It is not suitable for long-term use.

As another prior art, Korean Patent Laid-Open No. 10-2013-0036749 discloses an opening-and-closing type screening apparatus installed on a door frame of a sliding window.

In the present invention, an opening and closing type anchor is installed on the door frame of the lower end of the door crossing point to form an indirect channel, and a rail cover is made of an aluminum material to cover the opening of the railway door to naturally open the rainwater inflow, The organic function such as blockage of the membrane, rail cover, and indirect water channel simultaneously cuts out the outside air and the inside air flow, maximizing the airtightness, thereby saving energy, soundproofing, This is about a film that can be further raised.

However, in this case, since the rail is directly covered with the curtain, the movement of the window may not be easy, and at the same time, there is a problem that the window can not be prepared for situations such as rubbing or worn.

Therefore, in order to solve the above-mentioned problems, there is a need to develop a system window which improves the airtightness between the windows to increase the heat insulation performance by blocking the flow of air circulating between the window frame and the window frame.

1 and 2 and 3, a system window having improved airtightness between windows 300 includes upper and lower horizontal frames (not shown) formed with at least one coupling hole 111 into which the fastener 430 is inserted 110 and a vertical frame 120 on the left and right sides; A pair of rails 200 protruding from the inner surface of the horizontal frame 110 in parallel with each other in the horizontal direction through the coupling hole 111 and forming a gap space with the horizontal frame 110, ; A plurality of windows 300 having rail grooves 310 which are horizontally extended in the upper and lower parts to slide along the rail 200; A spring 600 which is fixed to the coupling hole 111 through the fastener 430 to provide elasticity and a spring 600 which is connected to the boundary between the horizontal frame 110 and the vertical frame 120 And a support panel 410 that is elastically supported through the spring 600 to seal between the rail 200 and the window 300 in a state where the support panel 410 is fixed to the window 300. [ do.

First, the window frame 100 is mounted on a wall of a building to serve as a frame for fixing the window. The window frame 100 is generally formed in a rectangular shape, and a window 300 is installed through the central portion of the window frame 100 . In this case, the horizontal frame 110 extending in the horizontal direction and the vertical frame 120 extending in the vertical direction are formed on the left and right sides of the upper and lower sides, respectively. Here, at least one coupling hole 111 into which the fastener 430 is inserted is formed in the horizontal frame 110.

At this time, in the horizontal frame 110, at the surface of the horizontal frame 110 facing the inner side of the window frame 100 (i.e., the lower horizontal frame 110 is the upper surface, the upper horizontal frame 110 is the lower surface The rail 200 may be further formed to face each other. The rail 200 is extended in a horizontal direction (in the same extension direction as the horizontal frame 110) on the surface of the horizontal frame 110, ) Are formed in parallel with each other. However, since the window 300 is directly mounted on the rail 200 to be slidably moved, a sufficient space must be provided between the at least two windows 300 so that the windows 300 can overlap with each other. The space between the horizontal frame 110 and the two rails 200 may be referred to as a gap space.

When the window frame 100 is prepared, the window 300 is inserted into the window frame 100 and slidably moved. Here, the window 300 may be composed of a glass panel and a window frame that surrounds the glass panel. The glass panel 300 may be provided with a rail groove 310 which is fitted to the upper and lower portions of the glass panel, The rail groove 310 is provided in the window frame 300 so that the rail groove 310 can be engaged with the rail 200 to be slidably moved. In addition, since the window 300 has at least two windows, the rails 200 are also provided in pairs so that at least two windows 300 are provided.

Next, the air gap plate described above may be included in the gap space. The windshield plate 400 is configured to prevent winds or heat from entering or exiting due to a gap generated between the window frame 100 and the rail 200 or the window 300, As shown in Fig. In this case, the wind plate 400 is characterized in that it includes a spring 600 fixed to the coupling hole 111 via a fastener 430 to provide elasticity, and a spring 600 extending in a state having a width equal to the width of the gap space And a support panel 410 which is elastically supported via a spring 600 in a state where both ends are fixed to a boundary portion between the horizontal frame 110 and the vertical frame 120. In this case, the support panel 410 may be made of a material having elasticity.

4 is a conceptual diagram showing an embodiment of a windward plate structure of the present invention.

4 (A), 4 (B) and 4 (C) show a front surface, a rear surface, and a vertical cross-section, respectively, of the sidewall plate 400, .

At this time, if the central portion of the support panel 410 is continuously subjected to the force through the spring 600, there is a problem that only the portion receiving the force through the spring 600 is stretched and may be broken or broken . In order to solve this durability problem, the support panel 410 is mounted on the horizontal end of the main panel 411, and is formed of a non-stretchable material. Panel 415 as shown in FIG. That is, by giving the elasticity of the extension panel 415 located at both ends of the main panel 411 to the main panel 411 which is in direct contact with the spring 600 to receive the force, the force is received by the main panel 411, The extension and contraction of the spring 600 is performed on the extension panel 415 so that durability can be improved.

At this time, the following structure may be further applied to the extension panel 415 in order to further enhance the elasticity. First, an incision part 412 cut horizontally is formed at the central part of the extension panel 415, and the first extension part 413 and the second extension part 413, which are separated from each other by the incision part 412, (414). This separation is also related to the role of the landing plate 400. The landing plate 400 supports the window 300 in all situations, such as when the windows 300 are overlaid on each other or when they are facing each other . At this time, there is no great correlation in the case of overlapping. However, when facing opposite to each other, substantially only half of the support panel 410 comes into contact with the window 300, and the other half is located at a position where there is no window 300 . Therefore, if half of the support panel 410 located at a position where the window 300 is not present receives the same elasticity from the spring 600, there is no way to solve it, which is a very unstable state. Therefore, if the both ends are connected to each other by the extended portions 413 and 414, not only the force can be dispersed but also the stress due to the excessive elasticity of the spring 600 can be reduced can do.

When this structure is temporarily provided, the support panel 410 is positioned in the gap space in the shape of an arcuate or trapezoidal shape. However, this configuration has the problem that the support panel 410 may be leaked or circulated through the open side when it is subjected to the force. The configuration of the diaphragm 417 extending vertically toward the horizontal frame 110 at the vertical ends of the main panel 411 and the extension panel 415 is formed of an elastic material so as to prevent the opened side surface . ≪ / RTI > The diaphragm 417 is most ideal to extend to touch the horizontal frame 110, but it is not necessary that the extended length is sufficient to touch the horizontal frame 110, It is basically blocked by the rail 200, and it can of course serve as the diaphragm 417 sufficiently.

At this time, however, the extension portions 413 and 414 may still be exposed to excessive expansion and contraction, and thus there is a need to further disperse the stretchable portion. In order to solve this problem, a first mounting groove 701 and a second mounting groove 702 are formed on both sides of the main panel 411, respectively. The first mounting groove 701 is formed on the surface of the main panel 411 facing the inside of the window frame 100 while the second mounting groove 702 is formed on the surface of the main panel 411 facing the horizontal frame 110 Plane. It should be noted, however, that the mounting grooves 701 and 702 are formed at positions spaced apart from both ends in the horizontal direction by a predetermined distance as shown in the figure. After the extension panel 415 is placed in a state of being slightly overlapped with the main panel 411 without directly connecting the extension panel 415 to the main panel 411, the first extension portion 413 and the second extension A first connecting band 711 made of an elastic material is further attached to the end of the portion 414. The first connecting band 711 is inserted into the first mounting groove 701 and is coupled through a fixing method such as adhesion or pressing so that the first extending portion 413, the second extending portion 414, (411) are elastically connected to each other. The second connecting band 712 may be connected to the second mounting groove 702. The second connecting band 712 may be connected to the first extending portion 413 and the second extending portion 414 And the other end is inserted into the second mounting groove 702 while one end is coupled to the surface facing the horizontal frame 110.

At this time, the first connection band 711 and the second connection band 712 are preferably configured to have a width equal to or slightly larger than the widths of the first extension portion 413 and the second extension portion 414 This is because the first connection band 711 and the second connection band 712 cover the space separated from the extension panel 415 and the main panel 411. This is because the first connecting band 711 and the second connecting band 712 are elongated and contracted, and the length is increased while the width is reduced when the first connecting band 711 and the second connecting band 712 are elongated.

In addition, FIG. 4D is an enlarged view of the vertical section, and a unique vertical section configuration of the main panel 411 can be seen through the enlarged vertical section.

That is, the main panel 411 may have a plate shape, but may have a more complex profile as shown in (D). That is, when the outermost portion is designated as the start point 801 and the center portion is designated as the end point 805, the first curve portion 801 formed to be convex inward in the first curve from the start point 801 to the first inflection point 802 A second curve portion 832 formed to be convex outward from a first inflection point 802 to a second inflection point 803 by a second curved line that is smaller than the first curved line and a second inflection point 832 formed from the second inflection point 803 to a third inflection point 803, A third curved portion 833 formed outwardly convex by a third curve larger than the second curved line from the third inflection point 804 to the end point 805 and a horizontal portion 834 formed horizontally from the third inflection point 804 to the end point 805 are symmetrically Respectively.

In the case of the first curve portion 831, by forming concave portions in contact with the extension panel 411 (the first extension portion 413 or the second extension portion 414), a space in which the extension panel 411 can be mounted (Particularly the second connection band 721) of the first connection band 711 and the second connection band 721 is extended through the first curve portion 831 to the extension panel 411 The portion where the concave portion of the first connecting band 711 is separated from the first connecting band 711 through the first bending portion 831 and the second bending portion 832 is constructed to prevent the problem such as friction and tension change due to friction, The second connection band 721 and the first connection band 711 are separated from each other to prevent the same problem. In addition, the first bend section 831 is configured to be able to be lifted up and down by a certain degree by the second bend section 832. This is because the first bend section 711 and the second connection bend section 721 extend and contract The first bend section 831 is moved up and down so that a more flexible grip can be formed. Further, the second bend section 832 and the third bend section 833 elastically support the first bend section 831 at different slopes. When the first bend section 831 is supported at one slope The first connecting band 711 and the second connecting band 721 are provided with a portion having a different inclination by one step when the second connecting band 711 and the second connecting band 721 are maximally extended to prevent the case where the first connecting band 711 and the second connecting band 721 can not be restored to the over- would.

At this time, although the drawing shows that the extension panel 411 is hardly inserted into the concave portion of the first curve portion 831 in order to show the shape of the first curve portion 831 in detail, The extension panel 411 may be extended to a sufficient length so as not to be easily detached from the concave portion of the first curve portion 831 when the extension panel 411 is extended.

Accordingly, through the above-described structure, the stretchability of the first extended portion 413, the second extended portion 414, the first connecting band 711, the second connecting band 712, and further to the main panel 411 The elasticity received from the spring 600 is divided and burdened, so that a stable elastic distribution can be achieved as a whole, thereby preventing a problem such as a force being applied to one side.

FIG. 5 is an enlarged view showing an embodiment in which a fixing structure is applied to a windward plate of the present invention.

The cover plate 731 covered with the same material as the panel 415 extending from the joining portion of the first extension portion 413 and the second extension portion 414 to one side in the horizontal direction is formed in the first connection band 711, And the cover plate 731 may be exposed to the outside according to the elongation of the first connection band 711. As mentioned in the foregoing description, each connecting band can be stretched and its width can be reduced, and when it is stretched, its durability is deteriorated, so that it is likely to be damaged if it is subjected to a force by the window 300 or the like. Since the first connection band 711 is located in a direction which is inevitably exposed in the case of the first connection band 711, It is necessary to protect the first connection band 711 from an external force by further including a configuration that can protect the first connection band 711 like the plate 731.

Further, if the cover plate 731 is detached from the first mounting groove 701, the cover plate 731 can not be properly performed. Thus, the cover plate 731 is prevented from being excessively discharged, and a hooking part 732 is further formed on one side of the end of the cover plate 731 and projected in the width direction. In the first mounting groove 701, And further includes a plurality of fastening rings 416 formed at both inner ends thereof to receive the fastening part 732. That is, a separate ring-ring bond is formed, so that the cover plate 731 is prevented from completely falling through the first mounting groove 701 through the ring.

Fig. 6 is a cross-sectional view showing another embodiment of the wind direction plate constitution of the present invention.

As another method of utilizing the main panel 411 and the extension panel 415, a locking protrusion 810 may be further formed at both ends of the main panel 411 in the horizontal direction so as to protrude along the ends thereof . As a corresponding structure, a plurality of fixing grooves 820 are further formed on the surface of the extension panel 415 overlapping with the main panel 411 by a predetermined distance along the horizontal direction. That is, the fixing groove 820 has a plurality of grooves in which the locking protrusions 810 can be engaged in association with the locking protrusions 810. At this time, a plurality of fixing grooves 820 are formed along the horizontal direction So that the locking protrusion 810 is caught in the fixing groove 820 at a position where the main panel 411 and the extension panel 415 are elongated at maximum and can be more stably fixed.

It is preferable that the width of the fixing groove 820 is larger than the width of the engaging protrusion 810. The extension panel 415 and the main panel 411 are pushed or extended by the expansion and contraction of the spring 600 When the widths of the fixing grooves 820 and the locking protrusions 810 are made the same, the locking protrusions 810 are stopped at positions where the fixing grooves 820 are not formed so that the locking protrusions 810 ) Can not be mounted.

A frictional pad 821 having a frictional force larger than the surface frictional force of the elongated panel 415 is provided on the surface on which the fixing grooves 820 are formed for facilitating the engagement between the fixing grooves 820 and the engaging protrusions 810. [ Even if the engaging protrusion 810 is completely inserted into the fixing groove 820 or the engaging protrusion 810 is positioned at a position where the fixing groove 820 is not formed, a high frictional force is exerted through the friction pad 821 So that the locking protrusion 810 can be mounted more strongly.

In this way, a problem may occur even if the space between the window 300 and the rail 200 is closed by providing the elasticity through the spring 600. That is, the surface of the support panel 410 pressed by the spring 600 may be uneven And the support panel 410 has an arch shape when it is pressed through the spring 600. This is because the end portion of the arcuate image may not be able to touch the window 300 properly. In order to solve such a problem, the following configuration may be further included.

Fig. 7 is a conceptual diagram of a configuration in which a membrane wall portion and an extending wall portion are applied to a drift plate of the present invention.

As shown in Fig. 7 (B), a film protruding and extending toward the inside of the window frame 100 so as to horizontally cross the main panel 411 on the surface of the main panel 411 of the support panel 410 440 extending from both sides of the wall portion 440 and the extending wall portion 443 to the position where both ends of the wall portion 440 are in contact with the vertical frame 120, And a mohair 442 which is fitted into the mohair insertion groove 441. The mohair insertion groove 441 may be formed by a plurality 7A, the curtain wall portion 440 is vertically extended from the surface of the main panel 411 and is inserted into each window 300 when the window 300 is superimposed thereon And the extension wall portion 443 extends from the both ends of the wall portion 440 toward the vertical frame 120 and is separated from the extension panel 415 by a window 300 located on the upper or lower portion of the extension panel 415, As shown in FIG. That is, since the extension panel 415 has elasticity as described above, when the extension part 415 is stretched or contracted, when the membrane part 440 is formed on the extension panel 415, Can not function properly. The extended wall portion 443 can be formed between the wall portion 440 and the window 300 located above or below the extended panel 415 separately from the extended panel 415. [ At this time, the mohair 442 is positioned between the wall portion 440 and the window 300, preferably, the mohair 442 contacts the side surface of the window 300, A space between the window 443 and the window 300 is blocked to prevent passage of wind introduced through the rail groove 310 of the window 300. [

Here, the mohair 442 means a member having a smooth volume characteristic with a certain volume, which is easy to expand and contract, and is applied to fill a gap that is not covered even after physical coupling in a sash with a physically fixed shape. The mohair 442 mounted on the mohair insertion groove 441 may be formed of a material such as a mohair 442 sold in the market if the length or area is suitable. ) Can be applied as it is.
