Abstract

The invention relates to construction, namely to soundproof windows, and can be used in the construction of houses located near noise highways. The purpose of the invention is to simplify the design and increase the sound insulation of the window. The noise protection window contains external and internal glazed partitions, on the last of which a valve covering the ventilation gap is articulated. A louvre is mounted on the external partition from the outside, and inside the window, the middle sash floor with through holes in the side ends is pivotally fixed to the partition. In the ventilation mode, the middle leaf deviates to adjoin the inner one and forms air ducts with labyrinth channels of variable cross-section and volume. 4 ill.

Description

The invention relates to construction and can be used in homes located close to noisy highways and airways. ,:,. ;.; - :;

The aim of the invention is to simplify the design and increase the sound insulation of the window. :

Figure 1 shows a window, a general view of the room; figure 2 is a section I-I of figure 1 with the open middle sash; on figs - t, about the same when the middle position of the sash is closed; in Fig.4 - section H-Pfig. 1.

The noise-proof ventilation window contains a frame 1, external and internal 3 and 4 attached to it by hinges 2, respectively, glazed partitions with ventilation slots between the racks 5,6 and 7,8, respectively. On the rack 8 of the internal partition 4 through the hinges 9 installed valve

10. The ventilation slit of the outer partition 3 is closed by a louvre grille 11, and on the pillar 6 inside the window, through the vertically removed hinges 9, is fixed a block of the middle sash 12 with through holes 13 at the side ends. The surface of the middle sash 12 along the perimeter of the abutment adjacent to the external partition, the surface of the abutment of the valve 10 to the struts 7.8 and the abutment surface of the partitions 3 and 4 to the frame 1 are equipped with sealing gaskets 14. The middle sash 12 is also equipped with a sound absorber 15.

The noise ventilation window is operated as follows.

To ventilate the room, open valve 10 and move the middle leaf 12 from the closed position shown in FIG. 3 to the position shown in FIG. 2 until it contacts the inside

a glazed partition 4. In this case, air will enter through the louvre grille 11 into the inter-glass space, then through the through holes 13, the cavity of the middle sash 12 and the ventilation gap between the posts 7 and 8 - into the room, as shown by the arrows in Fig. 2.

As the air duct has a variable volume, as indicated by the arrows in Fig. 2, the sound loses energy, due to which there is a reduction in the noise level coming into the room with air. With this, sufficient air exchange is ensured. The presence of sound absorbers 15 contributes to the improvement of soundproofing properties. windows when airing.

Claims (1)

The claims Noise-protective ventilation window, including the outer and inner glazed partitions with ventilation slots formed between the posts, of which the slot in the inner partition is blocked by a valve, and the middle shutter pivotally mounted on the outer partition with the possibility of adjoining to the inner partition, due to the fact that, in order to simplify the construction of the door, the middle leaf is hollow with through holes at the side ends for air passage . {ABOUT 0 AND 8 FIG 7 - f 1191511
