Description

Window that combines convenience of opening and closing and excellent airtightness}

The present invention relates to a window that has been improved to have excellent airtightness as well as convenient opening and closing of the window, and more particularly, by configuring a pressing member in a portion where the closed windows overlap each other, the insulation provided on the window frame in the process of closing the window Excellent airtightness can be secured by automatically pressing the member and the airtight member in close contact, as well as the convenience of opening and closing that can improve the convenience of use while reducing manufacturing costs as locking members such as crescent can be omitted. It relates to a window that combines and excellent confidentiality.

In general, most buildings, such as houses/apartments/villas/buildings, have windows installed on the outside, and these windows decorate the exterior of the building more beautifully, and serve as a passage to let in and out of sunlight and wind, preventing heat and cold. In addition to this purpose, in modern times, fireproof/waterproof/soundproof functions add a pleasant environment to residents.

Most of the windows are fixedly installed as an opening of a wall formed in a rectangular shape in a building, and a sliding window that is opened and closed by slide movement is installed on these window frames, and a locking member to prevent external intrusion is mounted on the window.

Here, as the locking member, a mounting bracket mounted on one window and a crescent-shaped rotation bracket mounted on the other window are typically used as a locking member to lock a pair of windows.

As disclosed in Korean Patent Registration No. 10-2023066, such a crescent is applied by pulling force toward each other in the process of engaging the mounting bracket and the rotating bracket together with the locking of the window, blocking the gap between the window and the window. It is implemented closely with the gasket.

On the other hand, a locking member is practically unnecessary for a window that is located indoors among windows that are double installed in an opening of a building, or that is installed in a place such as a veranda or a terrace in an outdoor side of the building's opening.

However, as mentioned above, the locking member plays a role of locking the window and blocking the gap by making the window and the gasket close together.

Therefore, there is a problem in that the cost and time required for manufacturing and installation are increased as the locking member must be installed in order to secure airtightness even for windows and doors installed in a location where the locking member is not required.

In addition, after closing the window, there is a problem in that the rotation bracket of the locking member must be manipulated to engage the mount bracket every time, causing inconvenience in use.

In addition, conventionally, gaskets such as mohair are mounted in close contact regardless of whether the window is opened or closed to block the gap between the window and the window.

That is, in the open state of the window, the gasket is always in close contact even though airtightness is not required, so that relatively high frictional resistance is generated while the window is slidingly opened and closed, thereby increasing the force required for opening and closing, causing inconvenience.

In addition, the gasket is damaged or deformed due to frequent friction with the window, so that even when the window is closed, the degree of adhesion between the windows is lowered, and thus the airtightness of the window is deteriorated.

Here, the window frames 21 are all extruded into a rod shape like the inner/outer frames 11 and 12, and the ends cut in diagonal lines are engaged with each other, and are mutually coupled in vertical and horizontal directions to form a square door frame.

Therefore, in order to aid understanding of the description, a lower portion of the window frames 21 constituting the rectangular window 20 will be described based on the lower portion disposed horizontally and horizontally like the window frame 10 described above.

The window frame 21 has an upper end (left) and a lower end (right) of each concave cross-concave formed.

That is, an insulating space S is created in the left concave portion of the window frame 21 to block heat transfer, and the corner member 22 and the window wheel 23 are inserted and mounted in the right concave portion.

The corner member 22 surrounds the window rail 13 and is formed in a ㅂ-shaped cross-sectional shape in which an insulating space is created therein.

The corner member 22 is inserted into the window frame 21 at the lower end, that is, at each outer rim of the window frame 21 assembled in a square shape.

Here, a slot having a T-shaped cross-sectional shape to which the corner gasket 24 and the fixing bracket 52 of the pressing member 50 are mounted is formed inside the lower end of the corner member 22.

The window wheel 23 is mounted at the lower end of the window frame 21 and performs a rolling motion along the window rail 13 to slide.

The corner gasket 24 is slide-fitted to a slot provided on the inside of the corner member 22.

These corner gaskets 24 are in close contact with both sides or one side of the closed window rail 13 to block the gap.

For reference, FIG. 4B is a cross-sectional view of the side of the window frame 21 overlapping the other window 20 based on FIG. 2, and FIG. 4A is a cross-sectional view of the side of the window frame 21 of the remaining portion.

Here, the corner gasket 24 is preferably formed to have a thickness that does not come into close contact with the window rail 13 in the open state of the window 20, and the reason will be described again together with the pressing member 50 to be described later. .

The glass window 25 is sealed with silicone while being placed in a double layer at a predetermined interval through a spacer on the top of the window frame 21.

Here, it is preferable to inject a transparent inert gas into the space between the windows 25 to block heat transfer while securing a view.

Subsequently, the heat insulating member 30 according to the present invention is extrusion-molded of polyamide, and is interposed between the inner/outer frames 11 and 12 as shown in FIGS. 1 and 2 to fill the gap with the window 20 and transfer heat. Blocks.

This insulating member 30 is a heat insulating plate 31 coupled to the lower side of the side of the inner / outer frame 11, 12, as shown in Figure 3, and the ㅗ-shaped cross-sectional heat insulating rod 32 coupled to the upper side of the It is divided into and organized.

Accordingly, an insulating space S is created between the insulating plate 31 and the insulating rod 32, that is, between the inner/outer frames 11 and 12, which blocks heat transfer.

Here, on both sides of the insulating plate 31 and the insulating rod 32, insulating protrusions 33 which are engaged with the coupling protrusion 15 and slide-fitted are protruding, respectively.

In addition, a slot having a T-shaped cross-sectional shape is provided on both sides of the vertically protruding portion of the insulating rod 32, and an insulating gasket 34 blocking a gap with the window 20 is slide-fitted to the slot.

At this time, a portion of the insulating rod 32 that protrudes vertically is formed as a hollow hollow inside to form an insulating space S that blocks heat transfer from one window 20 to the other window 20.

Subsequently, the airtight member 40 according to the present invention is vertically mounted between the insulating members 30 in which the closed windows 20 overlap each other as shown in FIGS. 1 and 2 to interlock with the closed windows 20 to block the gap. Do.

This airtight member 40 is composed of a rectangular airtight frame 41 and an airtight gasket 42 as shown enlarged in FIG.

The airtight frame 41 is extrusion-molded of aluminum or polyamide, and is fixedly mounted vertically between the heat insulating members 30 overlapping the closed windows 20.

The airtight gasket 42 is slide-fitted to the front/rear surfaces of the airtight frame 41 facing the window 20 to block a gap with the window 20.

Finally, the pressing member 50 according to the present invention is mounted on the upper/lower ends of the window frame 10 and the window 20 where the airtight member 40 is located, as shown in FIGS. 1 and 2.

That is, the pressing member 50 causes mutual interference between the window frame 10 and the window 20 toward the inside/outside at the point at which the window 20 is closed, so that the window 20 is connected to the heat insulating member 30 and the airtight member. Forces pressure to automatically close to (40).

As shown in FIG. 5, the pressing member 50 includes a fixing bracket 51 that is screwed to the upper end of the inner frame 11 adjacent to the airtight member 40, and a fixing bracket 51 as shown in FIG. 51) is composed of a flow bracket 52 that is coupled to one or more slides to the inside of the opposite corner member 22.

At this time, the pressing member 50 is shown to be composed only of the inner frame 11 and the corner member 22 of the window 20 mounted thereto, but in some cases, the outer frame 12 and the window 20 mounted thereto. ) Can also be composed of multiple.

That is, it can be applied to only one of the pair of windows 20 pressed by pressing when closing, and can be applied to all of the pair of windows 20.

First, as shown in FIG. 5, the fixing bracket 51 is formed in a b-shaped cross-sectional shape protruding vertically and horizontally so as to be in close contact with the upper surface of the inner frame 11 and the side surface of the window rail 13, respectively.

Here, at the center of the horizontal portion in close contact with the inner frame 11, one or more coupling holes 51a for inducing screwing are vertically penetrated.

It is preferable that the inner rim of the coupling hole 51a is formed by countersinking corresponding to the shape of the head so that the head of the screw is concealed.

In addition, a fitting protrusion 51b is formed on one surface of the vertical portion in close contact with the window rail 13 to protrude horizontally so as to induce a slide fit on the side of the window rail 13.

That is, as the fitting protrusion 51b is fitted to the locking protrusion 13a formed on the window rail 13, the coupling hole 51a may be omitted in the vertical portion.

Therefore, the fixing bracket 51 provides an advantage of easy installation as tight coupling is possible only by screwing through the coupling hole 51a.

Here, the other surface of the coupling protrusion 51b is formed with a pressing piece 51c that extends and protrudes in the thickness direction and selectively comes into contact with the flow bracket 52 which slides along the window 20.

That is, the pressing piece 51c causes interference with the flow bracket 52 moving along the window 20 and presses the window 20 in the opposite direction of the pressing piece 51c.

At this time, inclined surfaces 51c-1 are formed on one or both sides of the pressing piece 51c, which is in contact with the flow bracket 52, that is, the interference starts.

This inclined surface 51c-1 is formed as a curved surface gently rounded in the entry and exit direction of the flow bracket 52 so that the interference protrusion 52a of the flow bracket 52 to be described later is gradually pressed.

Therefore, while preventing noise in the process of closing the window 20 by the inclined surface 51c-1, it is possible to induce a smooth closed movement of the window 20 to satisfy the overall user's desire.

In addition, a stop groove (51c-2) is formed in the pressing piece (51c) at the point where the interference protrusion (52a) of the flow bracket (52) stops due to the complete closing of the window (20).

These stop grooves (51c-2) are concave and concave formed to engage and restrain the interference protrusion (52a) which is pressed in the state the window 20 is completely closed.

Therefore, the window 20 can continuously maintain the closed state even with external forces other than the open external force, that is, external force generated from the wind or the buffer member.

Subsequently, the flow bracket 52 is formed in a ㅕ-shaped cross-sectional shape so as to be slide-fitted into a slot provided in the corner member 22 as shown in FIG. 5.

That is, the flow bracket 52 has a plate-shaped body having a size covering the slot of the corner member 22, and a hook-shaped fitting piece that protrudes upward and downward from the rear of the body and slides into the slot, Has a formed structure.

The flow bracket 52 extends horizontally to one surface facing the pressing piece 51c to form a dome-shaped interference protrusion 52a that slides and presses into contact with the pressing piece 51c.

Here, the interference protrusion 52a is not limited to a dome shape, and may be formed in a triangle or a square with rounded corners when viewed from a plane.

In this case, as shown in FIG. 7, the flow bracket 52 may further include a fixing piece 52b extending and protruding to the other surface in the direction to be inserted into the corner member 22.

The fixing piece 52b moves along the window 20 and acts as a stopper to prevent slipping in the slot of the corner member 22 in the process of interfering with the pressing piece 51c.

Hereinafter, the operation of the pressing member 50 according to the opening and closing of the window 20 according to the present invention and the pressing process of the window 20 due to the pressing member 50 will be described as follows.

First, when the window 20 is open, the fixing bracket 51 and the flow bracket 52 are spaced apart from each other as shown in FIG. 8A.

That is, when the window 20 is opened, the heat insulation gasket 34 of the heat insulation member 30 and the hermetic gasket 42 of the hermetic member 40 are spaced apart from the window frame 21 as shown in FIG. 9. And have a gap (T).

In addition, the corner gasket 24 of the window rail 13 and the corner member 22 is also spaced apart from each other to have a gap T.

Accordingly, as the open window 20 has a state separated from the corner gasket 24 or the heat insulation gasket 34, the window 20 can be opened and closed with a small force due to the significantly lowered frictional resistance.

Above all, it is possible to prevent damage or deformation of the corner gasket 24 to the airtight gasket 42, thereby ensuring a high service life.

Subsequently, when the closing of the window 20 begins, as shown in FIG. 8B, the pressing piece 51c of the fixing bracket 51 and the interference protrusion 52a of the flow bracket 52 interfere with the pressing piece 51c. They are spaced apart from each other by the sum of the thickness and the protruding length of the interference protrusion 52a.

That is, when the fixing bracket 51 and the flow bracket 52 interfere with each other, the window 20 moves toward the corner gasket 24 to the airtight gasket 42 to establish close contact with each other as shown in FIG. Will have.

Therefore, since the window 20 is automatically pressed into close contact with the heat insulating member 30 and the airtight member 40 provided on the window frame 10, excellent airtightness can be expected.

Finally, when the closing of the window 20 is completed, the interference protrusion 52a of the flow bracket 52 is engaged with the stop groove 51c-2 of the fixing bracket 51 as shown in FIG. 8C to have a constrained state. do.

Therefore, as long as the user does not apply an open external force, it can continuously maintain a stable closed state like the existing Crescent.

In the above, preferred embodiments of the present invention have been illustrated and described, but the present invention is not limited to the specific embodiments described above, and is generally used in the technical field to which the present invention belongs without departing from the gist of the present invention claimed in the claims. Of course, various modifications may be implemented by those skilled in the art, and these modified embodiments should not be individually understood from the technical spirit or prospect of the present invention.
