Description

118543

The invention relates to a window structure comprising a valve adapted to act as an air flow control valve.

State of the Art 10 Window structures are now increasingly equipped with replacement air intake valves. There are a number of window frame designs available on the market. Existing designs require an opening through the window frame. This causes the window frame to become significantly thinner at the opening, causing a reduction in the technical properties of the window. Window attachment becomes more difficult, window latches are more difficult to install, jambs are more difficult to mount, frame strength is reduced, and flotation of the duct gap also causes problems. In addition, replacement air devices are installed in an opening against unprotected wood, whereby condensation moisture can cause window decay and, (.t mold damage. Substituting air holes cause production problems and confusion, because only some windows will have openings and j into windows). guide two or three *** ·. ···, 20 apertures This also causes problems when installing windows on the site, as • • · · ♦ small windows can have unopened, single, double or triple apertures.

···· • · · · · ·; * · *: In prior art solutions, the valve was made in a frame structure. To this end, separate arrangements were needed to direct the airflow into the duct provided in connection with the frame structure and further through the valve structure to the room. In this application, ϊ *: avoids interference with the frame structure. No separate flow channels that technology. ** ·. level solutions were made in connection with the frame structure, there is no need to create it separately in this ice-breaking embodiment of the invention. The application utilizes the gap between the frame structure and the wall surface into which the valve is fitted. The valve is fastened to the upper surface of the frame structure 30 by screws, and preferably a valve structure comprising a separate housing * · '* is used. The inlet end of the enclosure is bent downwardly so that it opens in the direction of the window plane 2 118543 and thereby provides the best possible way to direct replacement air inside the enclosure structure and further into the room. The valve fitting is made by means of a separate inner cover strip, preferably a wood cover strip, by screwing a through opening for the valve.

According to the invention, the housing structure is screwed onto the upper surface of the frame. The fact that the valve is located on the upper surface of the frame is the most advantageous solution for air circulation. However, the invention is not intended to be limited solely to the aforesaid position, but the valve may also be located in other frame members, for example, vertical frame members, and so on, such that it is housed in a space between the vertical frame member and the wall element. Once the frame is in place, the spaces between the frame and the wall are filled with cellular plastic, preferably polyurethane. The polyurethane hardens in place due to the effect of the air and permanently attaches the valve to a specific mounting point. The polyurethane also seals the structure so that no air leakage occurs outside of the valve housing structure.

The invention is characterized by what is stated in the claims.

The invention will now be described with reference to certain preferred embodiments of the invention shown in the figures of the accompanying drawings, which are not, however, to be construed as merely limiting the invention.

Figure 1 is an axonometric view of a structure according to the invention. The air flow control regulating device L1, or valve 10, comprises a frame part 11, fixed by screws R on the upper surface K 'of the window frame K. The frame parts of the window are shown by a reference handle B. According to the invention, the valve 10 is disposed on the upper surface of the frame part K1 above the window frame and is fastened to the upper surface K 'by screws R. It is located between the frame K and wall E.

In the figure, the valve 10 at its end opening into the room is arranged to pass through the opening 13a of the inner cover strip 13. Thus, the inner cover strip 13, preferably made of wood, is provided with an opening 13a through which the valve 10 is passed through its body 11 and out of which 10 the protruding wall 1 Id of the elongated flow upwardly guiding the body 11 of the valve 10 and the end wall 12 '. By pulling the slide member 12 fully out, the valve 10 can be easily cleaned.

Thus, the valve 10 according to the invention is simple to install and does not require any special arrangement when compared to a valve to be inserted into the frame. It is only necessary to provide one inner cover strip 13 with a through hole 13a for the valve 10 to pass through. Furthermore, the valve body 11 is easy to construct so that the air flow Li through the valve can be drawn in the direction of the window surface, the body 11 of the valve 10 having an inlet portion 1a and perpendicular to the upper surface K 'of the upper surface K'. · ·. ···, 20 of its share 1 Ib. Thus, the flow Li first enters upward (L) and turns to a portion of 1 lb · · ··· (L) and passes through the flow space defined by the skate member 12 within the body 11 to the end of the skate member 12 and further, depending on the slide position. *: *. amount of room space.

Figure 2 shows a section I -1 of Figure 1. As shown in the figure, the valve 10 is disposed with the window opening E 'of the wall E so that the valve 10 is located on the upper surface K' of the frame K. ···. and the wall E 'defining the window aperture wall E'.

• · · ♦ «• · *. Frame K and window aperture E 'are formed such that the window aperture forms ··· * ”*. The wall interface E 'further has a vertical portion E "attached thereto. Thus, the frame is adapted to provide a kind of wall E recess. The casing Ranko 11 comprises a casing section 11a extending downwardly as shown in FIG. that the supply air flow, as shown by arrow Li, enters the flow state D of the valve body 11 in a direction parallel to the plane of the window glass, said flow space D comprising a slide section 12 which at its end comprises a sloping wall section 12 'corresponding to a slope portion can be moved in space D inside the housing 11 with the slanting wall portion 12 'of the slider portion 12 in the closed position against the sloping wall portion 1 Id of the housing body 11. The airflow A between the sloping wall portions 1 Id and 12' can thus be closed and opened 11 movement e C 1 and C 2 are located between the upper surface 11 'of the housing 11 and the wall 10 E.

Fig. 3 is a sectional view Π - Π of Fig. 1. As shown in the figure, the polyurethane insulator U is fitted between the window frame K and the wall E for those parts where the housing body 11 of the valve 10 does not exist. This prevents airflow Li other than through valve 1015.
