Description

The invention relates to a sound and heat insulating composite window according to the preamble of claim 1 and aims to further improve such composite windows with sound insulation ventilation.

In such a compound window, each of the two ventilation units, which consists of a core or a rotatable roller and a surrounding jacket or housing, must on the lower wing and upper wing of the main wing through an end opening in the corner area of the main wing are inserted in the longitudinal direction. This requires an additional manufacturing and processing effort, and it is also difficult to accommodate in the space between the provided reflector, blackout or the like, which can also be designed as snap blinds or blind inserts, in a simple and space-saving manner so that the blinds can be easily operated that two roller blinds arranged side by side in parallel in the space between the panes can be used both for additional thermal insulation and for using the different temperature influences acting on the outside and inside of the window to improve the ventilation effect and heat recovery and that the incidence of light when the blinds are open is impaired as little as possible .

There is already a ventilation device with a rotary valve provided with air flow openings and an external profile equipped with air flow openings for windows, doors, facades or the like (DE-OS 30 00 720), in which the rotary valves have labyrinthine ventilation channels with opposite stepped boundary surfaces which prevents direct airborne sound transmission and thus a corresponding sound insulation should be achieved. The stepped, opposite boundary surfaces of the ventilation ducts can be provided with sound-absorbing means in the form of a coating or a film, but the distance between the opposite, stepped boundary surfaces is so large that a straight-line sound passage is nevertheless possible between opposite gradations, so that the sound insulation is not in the desired dimensions.

The rotary valves of this ventilation device also have only two diametrically opposed air passages, namely an air inlet on one circumferential side of the rotary valve and an exhaust air opening on the opposite circumferential side, so that only air passage from the outside of the window to the inside of the window or vice versa, but not to the space between the glazing a compound window is possible. This ventilation device is therefore not to be installed in composite wing constructions of normal design. Although it has two side-by-side rotary valves which can be actuated in the same direction and synchronously, such ventilation devices can only be installed on windows and doors below and above, without a common actuation of such lower and upper ventilation devices.

The invention has for its object to further simplify and improve the construction of such sound and heat insulating composite windows with sound insulation ventilation in their construction.

This object is achieved essentially by the characterizing part of claim 1, while particularly advantageous developments of the invention are characterized in claims 2 to 9.

The invention has the advantage that the core of each of the two ventilation units is mounted directly on the shaft profile forming the lower wing part and the upper wing part of the main wing, which is open towards the space between the panes and does not require an additional jacket or housing. During assembly, the core can be opened into the space between the panes in the Cross-section U-shaped shaft profile simply inserted from the open cross-sectional side, which is then closed by a cover, which also forms a counter bearing for the core or for the rotatable roller of each ventilation unit and has the air passages to the space between the panes.

About which the lower wing piece and the Flü ^g eloberstück of the main wing forming U-shaped chute ^p rofile possible to make versatile, the bottom of each slot profile may be a strip-shaped support bearings used subsequently for the core.

To further simplify the ventilation units each Lüftun are the core ^g seinheit only two longitudinal rows of air passages at an angle of about 90 ° to 150 °, preferably about 120 ° to 130 °, to the longitudinal axis of the core, wherein namely dispensed that ventilation position, connects the outside of windows, the window inner side and the _'space between the panes with one another simultaneously. However, this ventilation position has not proven to be necessary.

In a further improvement of the invention, which also contributes to a simpler manufacture of the core of the ventilation units, the core between the air ducts can have a meandering air slot which is continuous over its entire length and has several folds in cross section, the side walls according to a further feature of the invention of the louvre between the side air ducts do not run parallel to each other, but have different curvatures. The sound entering the core or the roller is diffracted several times in this way by structurally particularly simple measures, the for a particularly good dispersion Sound waves is provided in that the side walls of the _L uftschlitzes are run by the different curvatures in varying mutual distances from each other and repeatedly curved. Due to the cross-sectional changes or swellings of the slot thus formed, the sound is also dampened with respect to the frequencies and to the changing length of the passage, so that the intensity of the sound is reduced accordingly. The length of the sound path from the entrance to the exit is multiplied compared to the diameter of the core.

A further improvement of such composite window results further characterized when the two Flü elseitenstücke ^g of the main wing of the same U-shaped, consist pane gap is open towards the shaft as the profiles Flügelunter- and upper wing pieces. It can then be arranged without constructive changes in the wing side pieces of the main wing horizontally extendable roller blind inserts, with two parallel longitudinal guides for the roller blinds of the two roller inserts, in which the Blinds from the two opposite wing side pieces can be moved past each other in the horizontal direction alternately to the closed position.

In addition to the ease of use of such horizontally extendable roller blinds, depending on whether a single blind roller blind or both blind roller blinds are pulled out at the same time, there is optimal additional heat or cold protection and a possibility of blackout.

By using the shaft profiles for the Wing elsei- ^q least malice of the main wing, the further advantage, _d ate to avoid the ventilation-questionable turn-tilt position of window sashes, the air outlets already present on the shaft profiles can be used as permanent ventilation, whereby filter strips can be arranged between the air outlets in the wing side pieces. In addition, there is a particularly space-saving and easy-to-assemble arrangement of the chain or toothed belt drives provided for the joint adjustment of the upper and lower ventilation units in the shaft profiles between the air passages, the adjustment of the ventilation units being able to be designed in a particularly user-friendly manner by means of a slide that is adjustable relative to a scale.

• Bei Winddruck wird der äußere Nebenflügel in die Dichtung am _Hauptflügel gedrückt und dadurch auf besonders einfache Weise eine Schlagregensicherheit und Fugenundurchlässigkeit des Verbundfensters erreicht. Der nach außen öffnende Nebenflügel erleichtert außerdem das Säubern der Verglasungen von innen und außen und erlaubt deshalb ganz neue Fensterkombinationen. Zum Putzen lassen sich die Nebenflügel gegenüber dem Hauptflügel wechselweise öffnen, und es ist auch eine "Festverglasung" eines der beiden Nebenflügel möglich, wenn ein Zugang durch den Nebenflügel an der gegenüberliegenden Fensterseite gegeben ist. Bei Kombinationen von Fensterflügeln können größere, festgesetzte Hauptflügel verwendet werden, weil die äußeren Nebenflügel sich so nach außen öffnen und umschlagen lassen, daß sie vom Nachbarfenster aus geputzt werden können. Ferner können von innen putzbare "festverglaste" Fensterteile unbeschränkt kombiniert werden, was für die Gestaltung von Fensterwänden und deren Nutzung als Sonnenkollektoren in Verbindung mit der erfindungsgemäßen Schalldämmlüftung auch wirtschaftlich interessant sein kann. Im übrigen bietet das erfindungsgemäße Verbundfenster mit Schalldämmlüftung die Möglichkeit, die Fensterflügel nur für Einfachverglasung einzurichten. Der Glaseinstand an den Fensterflügeln kann dadurch verringert werden, und eine Belüftung des Glasfalzes kann entfallen, da aus wirtschaftlichen Gründen ohne weiteres eine sogenannte Naßverglasung vorgesehen sein kann. Verbessert wurde auch die notwendige Filterung der Außen- und zusätzlich der Innenluft, die durch die Lüftungseinrichtungen transportiert wird, durch den Einsatz von Trockenschichtfiltern, die auswaschbar oder als Einwegfilter bei geöffneten Nebenflügeln außen und innen als Band ringartig auf den Hauptflügel aufgelegt werden können und bei Verschmutzung durch einfache Verschiebung um eine Lüftungslochbreite erneut funktionstüchtig sind.

Finally, according to a further feature of the invention auptflügel on _H except for the inward-opening, a second side wing, be hinged outwardly opening side wing, whereby various advantages:

• In wind pressure of the outer side wing is pressed into the seal at the _H auptflügel and thereby achieved in a particularly simple manner, a driving rain and Fugenundurchlässigkeit of the laminated window. The side wing opening outwards also makes it easier to clean the glazing from the inside and outside and therefore allows completely new window combinations. For cleaning, the side wings can be opened alternately with respect to the main wing, and it is also possible to "permanently glaze" one of the two side wings if there is access through the side wing on the opposite side of the window. In the case of combinations of window sashes, larger, fixed main sashes can be used because the outer side sashes can be opened outwards and folded over so that they can be cleaned from the neighboring window. Furthermore, "permanently glazed" window parts that can be cleaned from the inside can be combined without restriction, which is also beneficial for the design of window walls and their use as solar collectors in connection with the sound insulation ventilation according to the invention can be socially interesting. In addition, the composite window according to the invention with sound insulation ventilation offers the possibility of setting up the window sashes only for single glazing. The glass opening on the window sashes can thereby be reduced, and ventilation of the glass rebate can be dispensed with, since so-called wet glazing can easily be provided for economic reasons. The necessary filtering of the outside and additionally the inside air, which is transported through the ventilation devices, has also been improved by using dry-film filters that can be washed out or used as a disposable filter with the side wings open and inside as a band on the main wing and when dirty are functional again by simply shifting one ventilation hole width.

The sound and heat-insulating Verburid window 10 is formed with a frame 11 and a composite sash 12, which consists of two separately glazed window sashes. The compound window has a main wing 16 and two secondary wings 17, 17a attached to it, of which only the secondary wing 17 opens inwards, while the second secondary wing 17a can be opened to the outside of the window 10a. Both secondary wings 17, 17a can be provided with single glazing.

Am _F lügelunterstück 16A and at the sash top piece 16B of the main wing 16 is located one each Schalldämmlüftung 18a, 18b with an adjustable core 40 with angled air passages 31, 33 between the outside of windows 10a and the window inner side 10b, wherein the Schalldämmlüftung with one adjustable ventilating unit 18a, 18b is formed, which has meandering shaped air channels, which can be connected to the outside and inside of the window 10a, 10b and to the pane 24. The main wing 16 has on its wing lower section 16A and on its wing upper section 16B a shaft profile 60 which is approximately U-shaped in cross section and is open to the space between the panes 24, on which the core 40 of each ventilation unit 18a, 18b at 62a over its entire length between the air passages 31 , 33 is mounted to the outside of the window 10a and the inside of the window 10b in a strip-like manner.

Each of the two U-shaped shaft profiles 60 is closed on the lower wing part 16A and on the upper wing piece 16B on its open cross-sectional side by a cover 61 which can be used subsequently and which also forms a counterbearing for the core 40 or for the rotatable roller of each ventilation unit 18a, 18b and which Has air passages 32 to the disc space 24, which are arranged between strip-shaped seals 62b, 62c with respect to the core.

At the bottom of each shaft profile 60, a strip-shaped support bearing 63 for the core 40 or for the rotatable roller of each ventilation unit 18a, 18b is retrofitted.

As can be further seen in FIG. 4, the core 40 of each _L üftungseinheit 18a, 18b, only two longitudinal rows of air passages 41, 43 at an angle 40a of about 90 ° to about 150 °, preferably about 120 ° to 130 °, to the longitudinal axis 40b of the core 40 are arranged such that by displacement or rotation of the core 40 of each ventilation unit 18a, 18b, optionally, the outside of windows 10a and the space between the panes 24, the _S cheibenzwischenraum24und the window inner side 10b or outside of windows 10a and the window inner side to be brought 1 Whether in ventilation compound can, as shown in the illustrations of FIGS. 7 to 9 described below, using various ventilation positions. Depending on the position, the outside or inside air flowing through the ventilation units is cleaned of suspended matter by the band-shaped dry-film filter 52 arranged in a ring between the main wing 16 and each of the two secondary wings 17, 17a along the side air passages 31, 33.

The core 40 or the rotatable roller can moreover be produced in a particularly simple manner from an extrudable material, such as plastic or light metal, since the air channels 41, 43 on the core 40 have a continuous cross-section to the longitudinal extent of the core 40 meandering shaped and several times bent in cross section louvre 49 are connected. The row of air channels 41, 43 can be subsequently drilled from the outside into the inner air slot 49 of the core 40.

The side walls 49a, 49b of the air slot 49 do not run parallel to each other between the side air channels 41, 43, but have different curvatures and are curved differently from each other so that the sound waves entering the air slot 49 are not uniformly reflected from one of the adjacent slot walls 49a or 49b to the opposite wall 49b or 49a, but are deflected differently and refracted several times.

As can also be seen in the drawing, the two wing side pieces 16C, 16D of the main wing 16 also consist of the same U-shaped shaft profiles 60, which are open towards the window space 24 as the lower and upper wing pieces 16A, 16B, and in the two shaft profiles 60 two mutually opposite, horizontally extendable roller blind inserts 19A, 19B are arranged, the roller blind sheets 19a, 19b of which are guided in two parallel longitudinal guides 19c on the horizontal covers 61 of the lower and upper wing parts 16A, 16B on both sides of the row of air passages 32 to the intermediate space 24 such that the two roller blinds 19a, 19b can be moved alternately in the horizontal direction past one another by the two opposite wing side pieces 16C, 16D until they close, as is shown in detail in FIG. 6 with the enlarged detail VI from FIG. 3.

The air passages 31, 33 on the U-shaped shaft profiles 60 of the wing side pieces 16C, 16D serve as permanent ventilation, and filter strips 64 are arranged between the air passages. In addition, the two trains or sections of the circulating chain or toothed belt drive 50 for the joint adjustment of the upper and lower ventilation units 18a, 18b are guided on the side main wing pieces 16C, 16D on both sides of the filter strip 64, the train or section lying on the inside of the window 10b over a slide 66 projecting through a slot guide on the inside of the relevant wing side piece 16C and adjustable relative to a scale 65 can be actuated in a simple manner.

Since in addition to the inward-opening secondary wing 17 struck on the main wing 16, a second, outwardly opening secondary wing 17a is also struck, glazing on the main wing 16 can be dispensed with. Single glazing 25, 26 in the two secondary wings 17, 17a are sufficient. Between the two glazings 25, 26 there is an approximately 8 cm wide air space, and due to the special design of the open shaft profiles 60, the ventilation chamber with a core arranged therein or with the rotatable roller is approximately 40 mm wide and approximately 40 mm deep accessible in full length. The static effectiveness of Profilwandun ^g s is attained only by the serving as the stopper cover 61 to the full.

7 to 9 show in detail how the heat from the outside of the window 10a and / or from the inside of the window 10b can be used for ventilation.

In Fig. 7 the sound insulation ventilation is in the ventilation position "summer". In the lower ventilation unit 18a, the rotatable core 40 with its two air channels 41, 43 connects the air passages 33 on the inside of the window 10b with the air openings 32 to the window space 24, and the core 40 of the upper ventilation unit 18b is in a position in which it Inter-pane space 24 connects to the outside 10a of the window. The roller blind 19b of the roller blind insert 19B, that is to say that the roller blind located near the inner glazing 26 is pulled out and absorbs through its special coating the incident solar radiation through the outer glazing 25 in such a way that it is converted into heat radiation in the middle infrared range and because there is glass in it Radiation area is impermeable to heat radiation, is not released again to the outside. The result is a so-called greenhouse effect, through which the air in the intermediate space 24 heats up and in additional lift is generated, the sponding ents for a ^p re- ventilation at the inside of the window 10b provides. At the same time, the extended roller blind 19b, which has a special coating reflecting heat radiation on the side facing the interior, in conjunction with the inner glazing 26 constitutes thermal insulation similar to an inner insulating glazing. The used room air is thus extracted from the room to be ventilated by the soundproofing ventilation, and, in addition, the extended blind sheet 19b prevents heating of the inside of the window 10b by the warm air present on the outside of the window 10a.

8 shows a ventilation position "winter" in which the lower ventilation unit 18a connects the window outer side 10a to the window space 24 and the upper ventilation unit 18b connects the window space 24 to the window inner side 10b. Here too, the roller blind 19b located next to the inner glazing 26 is extended, so that winter sunlight from the outside of the window can be used in the manner just described for the supply of fresh air to the inside of the window 10b. There is a so-called sun trap. In addition, the roller blind 19b in connection with the inner glazing 26 also serves as thermal insulation similar to an inner insulating glazing and prevents the transfer of room heat and thus the loss to the outside of the window.

Also in FIG. 9, the sound insulation is in the ventilation position of FIG. 8, but not the inner blind sheet, but rather the blind sheet 19a of the blind insert 19A which is closer to the outer glazing 25 and which has a coating reflecting heat radiation on both sides .

In this case, thermal insulation in the manner of insulating glazing is achieved towards the outside of the window 10a, while the transmission heat entering from the inside of the window 26 through the inner glazing 26 into the space between the panes 24 hits the inside of the roller blind 19a, where it is reflected, and partly in the form of heat recovery for the Buoyancy of the supplied fresh air in the intermediate space 24 is made available.

By appropriate adjustment of the two fan units 18a, 18b of Schalldämmlüftung and by selectively extracting the roller blind webs 19a, 19b of the two roller blind inserts 19A, 19B are numerous other Lüftungsstellun ^g en avoiding condensation phenomena on the glazing possible, both with heat recovery as well as thermal insulation against the Heat transfer or the transition from cold to the window interior or vice versa.
