That is, the flow of outside air through the gap between the horizontal window frame 120 and the window frame 220 constituting each window assembly 200 can be blocked through the horizontal sealing member 141 .

At this time, the horizontal seal member 141 is further formed with a horizontal sealing member fixing end 142 fixed to the wall surface of the horizontal partitioning part 140 in a concave position, so that it is easy on the wall surface of the horizontal partitioning part 140 . It would be desirable to be able to install it easily.

In addition, the vertical partitioning part 130 is installed to protrude from the two vertical window frame frames 110 constituting the chassis assembly 100 while crossing between portions where each window assembly 200 is movably installed. .

At this time, it is suggested that the vertical partition 130 is made of a polyamide material, and through this, heat conduction through the vertical partition 130 is minimized to improve thermal insulation.

At the same time, on a wall of each wall of the two vertical partitioning units 130 opposite to the window frame 220 , a vertical wall that closes a gap with the window frame 220 while closely adhering to the window frame 220 . It is further suggested that the sealing member 131 is provided.

It would be desirable to be able to install it easily.

Next, when each window assembly 200 reaches the closed position of the chassis assembly 100 , the proximity moving part 230 moves the window frame 220 of the corresponding window assembly 200 to the adjacent vertical partition part. It is configured to move close to 130 .

The proximity moving part 230 is fixed in the accommodating groove 222 of the window frame 220 constituting the respective window assembly 200 and the accommodating member 111 provided in the chassis assembly 100 is provided in the accommodating groove. When accommodated in the 222 , the window frame 220 is provided with a pushing force by the receiving member 111 so that the window frame 220 can be moved close to the vertical partitioning part 130 .

Such a proximity moving part 230 is fixedly installed in the receiving groove 222, and the proximity moving part fixing end 231 and the proximity moving part fixing end 231 of each wall surface in the accommodating groove 222 are fixed. A pressing force providing end 232 formed to extend to be positioned on the wall of the vertical side partition 130 and the closest side, and to gradually protrude toward the receiving member 111 toward the inside of the receiving groove 222 . is comprised of

That is, in the embodiment of the present invention, each window assembly 200 is automatically brought into proximity to the vertical partitioning part 130 while moving in the closing direction through the provision of the proximity moving part 230, so that the vertical As the vertical seal member 131 provided in the side partition 130 and the window frame 220 of the window assembly 200 can be in close contact with each other, airtightness of the gap between each other is possible.

Furthermore, when the corresponding window assembly 200 is moved in the open direction, the pressing force from the receiving member 111 provided to the proximity moving part 230 is released, so that the window frame 220 of the window assembly 200 moves in the above-mentioned direction. Since it is spaced apart from the vertical sealing member 131 , the opening movement of the corresponding window assembly 200 can be smoothly performed without any interference from the vertical sealing member 131 .

On the other hand, the structure for airtightness improved window structure according to the embodiment of the present invention described above is a structure for airtightness between the window frame 220 located on either side of each window assembly 200 and the vertical side partition 130 adjacent thereto. For this reason, between the window frame 220 located on the other side of each window assembly 200 and the window frame 220 of another window assembly 200 adjacent thereto (two adjacent to each other on the central side in the drawing) between the window frames) is not secured.

Accordingly, in the embodiment of the present invention, as shown in FIGS. 4 and 5 , when the two window assemblies 200 are moved to the closed position, a gap between the window frames 220 constituting the two window assemblies 200 is It further suggests that a gap closure part 240 is further included to close the .

Here, the gap closing part 240 includes an installation bracket 241 fixed to one side of the outer wall surface of the window frame 220 constituting each window assembly 200 , and an end surface of the installation bracket 241 , respectively. It is configured to include a resilient cushioning member 242 for maintaining airtightness by blocking the gap between the two window frames 220 while being provided in the .

At this time, the elastic buffer member 242 is formed of a rubber material capable of elastic deformation and is configured to completely block the gap between the two window frames 220 .

The gap closure part 240 configured in this way is preferably provided to have a length corresponding to the length between the portion of the window frame 220 forming the upper side and the lower side of the window frame 220, so that it is provided long up and down, but the window assembly ( 200), it is preferable that the upper and lower lengths are shorter than the length between portions of the window frame 220 constituting the upper and lower sides of the window frame 220 as interference occurs during attachment and detachment. That is, the gap closing part 240 is configured to be spaced apart from each horizontal partition part 140 by a predetermined distance, so that interference can be minimized when the window assembly 200 is attached and detached.

Accordingly, a separation space will be formed between each horizontal partitioning part 140 and the gap closing part 240 .

On the other hand, in the embodiment of the present invention, it is further suggested that a gap airtight member 300 is further provided in the horizontal partition 140 .

The gap airtight member 300 is in close contact with the elastic buffer member 242 constituting the gap closing part 240 when the chassis assembly 100 is sealed through the two window assemblies 200 to improve airtightness. When the chassis assembly 100 is sealed through the two window assemblies 200 , the airtightness is improved by filling the space formed between each horizontal partition 140 and the gap closing part 240 . did it

The gap airtight member 300 is formed by protruding from the support part 310 to one side and the support part 310 to be fixedly installed on the horizontal partition unit 140 and supported therein, and to be in close contact with the gap closing part 240 . It is composed of a protrusion 320 that improves airtightness by providing an area, and it is preferably made of a shape similar to the letter 'T'.

Such a support part 310 is made in the shape of a square plate, and may be fixedly installed to each horizontal partition part 140 by an adhesive or a bolting method.

In addition, the protrusion 320 is formed in the shape of a rectangular flat plate, and is formed to protrude upward or downward from the support 310 .

On the other hand, the gap airtight member 300 is preferably made of an elastic body so that the adhesion with the elastic buffer member 242 can be increased and deformable by a physical force from the outside. That is, the protrusion 320 is configured to be bent to the left or right by a physical force applied from the outside, such as the window assembly 200 or a person, so that interference can be prevented when the window assembly 200 is attached and detached. Of course, when the physical force applied from the outside is removed, the protrusion 320 will have to be restored to its original state as shown in FIG. 6 .

That is, the gap airtight member 300 is made of an elastic body and is configured to be easily deformed and restored to improve workability.

Accordingly, the protrusion 320 may be fixed adjacent to the support 310 by a temporary fixing means such as an adhesive tape.

Therefore, when the window assembly 200 is attached and detached, the interference caused by the gap airtight member 300 can be eliminated, and through this, the removal and installation of the gap airtight member 300 when the window assembly 200 is attached and detached is additionally performed. The hassle of doing it will be reduced.

In addition, it is of course possible to configure the gap airtight member 300 so that only the protrusion 320 is made of an elastic body.

In the following, the action on the window structure with improved airtightness according to the embodiment of the present invention described above will be described in more detail.

First, attached FIG. 4 shows a state in which one of the two window assemblies 200 is partially opened.

In this way, one window assembly 200 is moved under the guidance of the guide member 121 protruding from the horizontal window frame 120 of the chassis assembly 100 and positioned in parallel with the other window assembly 200 back and forth. By achieving the state, the portion where the window assembly 200 was initially positioned before moving is opened.

On the other hand, when each window assembly 200 is moved to the closed position in the above-described state, one window assembly 200 closes one side of the chassis assembly 100 and the other window assembly 200 as shown in FIG. 5 . The window assembly 200 closes the other side of the chassis assembly 100 .

In particular, while the window assembly 200 is moved to the closed position as described above, the receiving member 111 provided in the chassis assembly 100 includes the receiving groove 222 of the window frame 220 constituting the corresponding window assembly 200 . In the process of being accommodated into the receiving groove 222, the pressing force providing end 232 of the proximity moving part 230 provided in the accommodating groove 222 is gradually pushed, and this causes the window frame 220 to be gradually moved to the vertical partitioning part 130. As the outer wall surface of the window frame 220 and the vertical seal member 131 provided in the vertical partition 130 come in close contact with each other, the gap for the corresponding portion is closed.

In addition, when the closing operation of each window assembly 200 is performed and each window assembly 200 is moved to the fully closed position, the elastic buffer member 242 of the gap closing part 240 is formed by the gap sealing member 300 . Further movement is prevented by touching the

In particular, in this case, the gap airtight member 300 fills the space between the elastic buffer member 242 and each horizontal partition 140, thereby preventing the flow of outside air and bet.

Accordingly, in a state in which the chassis assembly 100 is closed by the two window assemblies 200 , the window frame 220 located on one side of each window assembly 200 and the window frame 220 located on the other side of each window assembly 200 . is adjacent to the window frame 220 located on the other side of the vertical partition 130 and the other window assembly 200, respectively, the vertical seal member 131 and the elastic buffer member 242 and the gap airtight member 300 ) forms a closed state, and this prevents outside air from flowing into the room through each gap.

In particular, the horizontal seal members 141 provided on both side walls of the two horizontal partitioning parts 140 are in close contact with the window frame 220 on the opposite side, respectively, and block the air flow in the vertical direction by blocking the air flow in the vertical direction. The inflow of outside air into the room through the gap between the partition unit 140 and the window frame 220 is also prevented.

As a result, in the window structure with improved airtightness according to the present invention, when each window assembly 200 reaches the closed position, the proximity moving part 230 moves each part of the window assembly 200 to the opposite vertical partitioning part ( 130) and the other window assemblies 200, airtightness of all parts can be achieved when each window assembly 200 is closed.

That is, the horizontal seal member 141 and the gap airtight member 300 installed in the horizontal partition 140 by the forcible movement of the window assembly 200, and the vertical partition 130 installed in the The vertical sealing member 131 and the elastic buffer member 242 installed in the gap closing part 240 completely fill the gap between each window frame 220 or the gap between the window frame 220 and each partition part 130 and 140 . It becomes possible to seal, and the inflow of outside air through each gap can be fundamentally blocked.

Of course, when the opening operation occurs in the closed state of each window assembly 200, each window is spaced apart from the horizontal seal member 141 or the vertical seal member 131 and the elastic buffer member 242. During the sliding movement of the assembly 200, movement interference due to contact with each of the seal members 131 and 141 does not occur, and smooth sliding movement is possible.

On the other hand, the window structure with improved airtightness according to the present invention is not limited to being applied only to a structure in which both window assemblies 200 are slidably moved.

That is, it may be applied to a structure in which one window assembly 200 is fixed and only the other window assembly 200 is slidably moved.

In addition, it is natural that the window structure with improved airtightness according to the present invention can be applied to a double window structure. It is understandable that the right applicable to
