Description

according to patent ... (patent application P 30 43 783.3-25)

The invention relates to a sound and heat insulating composite window according to patent ... (patent application P 30 43 783.3-25) and has a further improvement of such composite windows with Soundproof ventilation to the goal.

In the case of the composite window according to the main patent application or according to the main patent, each of the two ventilation units that are made of consists of a core or a rotatable roller and a surrounding casing or housing, on the lower wing piece and on the upper wing

piece of the main wing through an opening on the front in the corner area of the main wing can be pushed in lengthways. This requires an additional manufacturing and processing effort, and there are also difficulties, the reflector, darkening strips or the like provided in the space between the panes, which are also used as snap-on blinds or roller blind inserts can be designed to accommodate in a simple and space-saving manner so that the blinds are operated easily can be that further two roller blinds arranged parallel next to each other in the space between the panes both for additional Thermal insulation as well as the use of those acting from the outside and inside of the window different temperature influences can serve to improve the ventilation effect and for heat recovery and that the incidence of light is impaired as little as possible when the blinds are open.

The invention is based on the task of training such Sound and heat insulating composite windows with sound insulation ventilation to further simplify and improve their structural design.

According to the invention, this object is essentially achieved by the Characterizing part of claim 1 solved, while in claims 2 to 8 particularly advantageous developments of Invention are characterized.

The invention has the advantage that the core of each of the two ventilation units directly on which the wing base and the upper wing piece of the main wing forming, towards the space between the panes open shaft profile is mounted and none requires additional jacket or housing. During assembly, the core can be inserted into the open space between the panes, in the

Cross-section U-shaped manhole profile can simply be inserted from the open cross-section side, which is then passed through a cover is closed each, which at the same time forms a counter bearing for the core or for the rotatable roller of each ventilation unit and the air passages to the space between the panes having.

Around the lower wing piece and the upper wing piece of the main wing Making U-shaped manhole profiles as versatile as possible can be used on the bottom of every manhole profile a strip-shaped support bearing for the core was subsequently inserted be.

To further simplify the ventilation units, there are only two longitudinal rows of air ducts at the core of each ventilation unit at an angle of about 90 ° to 150 °, preferably about 120 ° to 130 °, arranged to the longitudinal axis of the core, although on the one Ventilation position is dispensed with, the window outside, the window inside and the space between the panes at the same time connects with each other. 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 continuous cross section over its entire length, kinked several times, Have meander-shaped air slot, according to a further feature of the invention, the side walls of the air slot 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 generated several times in this way by means of structurally particularly simple measures flexed, being for a particularly good dispersion of the

Sound waves are provided by the fact that the side walls of the air slot through the different curvatures in changing mutual distances from each other and are curved several times. Due to the changes in cross-section formed in this way or swelling of the slot, the sound is also with respect to the frequencies and to the changing length of the passage way has an insulating effect, so that the intensity of the sound is reduced accordingly. The length of the sound path from Entry to exit is here multiplied compared to the diameter of the core.

A further improvement of such composite windows results furthermore, even if the two wing side pieces of the main wing are from the same U-shaped, to the space between the panes towards open shaft profiles such as the lower wing and upper wing pieces exist. It can then be horizontal without any structural changes in the wing side pieces of the main wing Extendable roller blind inserts be arranged, with the cover for the upper and lower wing pieces on both sides of the Row of air outlets to the space between the panes, two parallel longitudinal guides for the roller blinds of the two roller inserts can be in which the roller blinds from the two opposite wing side pieces in the horizontal direction can be moved past each other alternately to the closed position.

In addition to the ease of use of such horizontally extendable ones This means that roller blinds are one, depending on whether a single roller blind or both roller blinds are pulled out at the same time optimal additional heat or cold protection as well as a blackout option given.

By using the shaft profiles also for the wing side pieces of the main wing there is the further advantage,

! DOÖ I

that to avoid the turn-tilt position, which is questionable in terms of ventilation of window sashes, the air outlets that are already present on the shaft profiles are used as permanent ventilation can, wherein filter strips can be arranged between the air passages in the wing side pieces. Also results a particularly space-saving and easy-to-assemble arrangement of the for the joint adjustment of the upper and chain or toothed belt drives provided in the shaft profiles between the air outlets, the adjustment of the ventilation units by means of a slide that can be adjusted with respect to a scale is particularly user-friendly can be designed.

Finally, according to a further feature of the invention, in addition to the inwardly opening secondary wing, on the main wing a second, outward-opening secondary wing must be attached, which results in various advantages:

When there is wind pressure, the outer secondary wing is inserted into the seal on the Main sash pressed and thereby a particularly simple way a driving rain security and joint impermeability of the composite window achieved. The outward-opening secondary wing also makes it easier to clean the glazing inside and out outside and therefore allows completely new window combinations. The secondary wings opposite the main wing can be cleaned for cleaning open alternately, and "fixed glazing" is also possible for one of the two secondary wings, if access is through the side wing is given on the opposite side of the window. In the case of combinations of window sashes, larger, Fixed main wings are used because the outer secondary wings can be opened outwards and turned over, that they can be cleaned from the neighboring window. Furthermore, "permanently glazed" window parts that can be cleaned from the inside can be used without restriction can be combined, which is related to the design of window walls and their use as solar panels with the sound insulation ventilation according to the invention also economically

can be economically interesting. In addition, offers the invention Composite windows with soundproof ventilation offer the option of setting up the window sash for single glazing only. The glass inset on the window sash can be reduced and ventilation of the glass rebate can be omitted. because so-called wet glazing can easily be provided for economic reasons. Has been improved also the necessary filtering of the outside air and also the inside air that is transported through the ventilation systems becomes washable through the use of dry sheet filters or as a disposable filter with the secondary wings open, placed on the outside and inside as a band in a ring-like manner on the main wing and if they are dirty they can be operated again by simply shifting the width of a ventilation hole are.

In the following description are the same parts as in the main patent provided with the same reference numerals.

The sound and heat insulating composite window 10 is just like the main patent with a frame 11 and two separate glazed window sashes. However, in contrast to the main patent, the composite window consists of a main sash 16 and two attached secondary wings 17, 17a, of which only the secondary wing 17 opens inwards as in the main patent, while the second secondary wing 17a to the outside of the window 10a can be opened. Both secondary wings 17, 17a can be provided with single glazing.

On the lower wing piece 16 A and on the upper wing piece 16B of the main wing 16 there is a sound insulation ventilation with angled air passages between the outside of the window 10a and the inside of the window 10b, the soundproof ventilation with each one adjustable ventilation unit 18a, 18b is formed, which has meander-like shaped air ducts, which with the window outer and the inside of the window 10a, 10b as well as with the space 24 between the panes. The main wing 16 has on its lower wing piece 16A and on his Upper wing piece 16B each one open to the space between the panes 24, in cross section approximately U-shaped shaft profile 60 on to which the core 40 of each ventilation unit 18a, 18b at 62a over its entire length between the air passages 31, 33 The outside of the window 10a and the inside of the window 10b are strip-shaped is stored sealed.

Each of the two U-shaped shaft profiles 60 is on the wing base 16A and on the upper wing piece 16B on its open cross-sectional side completed by a cover 61 that can be inserted at a later date, which also has a GegonJager for the core 40 or forms for the rotatable roller of each ventilation unit 18a, 18b and has the air passages 32 to the space between the panes 24, which are arranged between strip-shaped seals 62b, 62c with respect to the core 40.

At the bottom of each shaft profile 60 is a strip-shaped Support bearings 63 for the core 40 or for the rotatable roller of each ventilation unit 18a, 18b are used subsequently.

As can also be seen in FIG. 4, there are only two longitudinal rows of air ducts on the core 40 of each ventilation unit 18a, 18b 41, 43 at an angle 40a of approximately 90 ° to approximately 150 °, preferably approximately 120 ° to 130 °, to the longitudinal axis 40b of the core 40 arranged such that by a displacement or rotation of the core 40 of each ventilation unit 18a, 18b optionally the Outside window 10a and the space between the panes 24, the space between the panes 24 and the inside of the window 10b or the The outside of the window 10a and the inside of the window 10b can be brought into ventilation connection, as shown below Described representations of Fig. 7 to 9 is shown on the basis of different ventilation positions. Depending on the position the ventilation units flowing outside or inside air is through the between the main wing 16 and each of the two secondary wings 17, 17a along the side air passages 31, 33 annularly arranged band-shaped dry film filters 52 from Cleaned suspended solids.

The core 40 or the rotatable roller can also be made of an extrudable material such as plastic in a particularly simple manner or light metal, since the air ducts 41, 43 on the core 40 by a continuous over the said length, transversely to the longitudinal extent of the core 40, a meandering air slot with a cross section bent several times 49 are connected. The row of air channels 41, 43 can subsequently be inserted from the outside into the air slot 49 of the inside Core 40 can be drilled.

The side walls 49a, 49b of the air slot 49 run in the the rest between the lateral air ducts 41, 43 are not parallel to one another, but have different curvatures and

are differently curved several times, so that the sound waves arriving in the air slot 4 9 are not uniform from one of the adjacent slot walls 49a or 49b to the opposite wall 49b or 49a, but rather be deflected differently and broken several times.

As can also be seen in the drawing, the two wing side pieces 16C, 16D of the main wing 16 also consist the same U-shaped shaft profiles 60 open towards the space between the panes 24 as the lower wing and upper wing pieces 16A, 16B, and in the two shaft profiles 60 are two opposite, horizontally pull-out roller blind inserts 19A, 19B arranged, their roller blind strips 19a, 19b in two parallel longitudinal guides 19c on the horizontal covers 61 of the lower wing and upper wing pieces 16A, 16B on both sides of the row of Air passages 32 are guided to the space between the panes 24 in such a way that the two roller blinds 19a, 19b are separated from the two opposite ones Wing side pieces 16C, 1 6D moved in the horizontal direction past each other alternately until they close can be, as shown in Fig. 6 with reference to the enlarged section VI of Fig. 3 in detail.

The air passages 31, 33 on the U-shaped shaft profiles 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 on the side main wing pieces 16C, 16D on both sides of the Filter strip 64 out, the train or section lying on the inside of the window 10b via a slot guide on the inside of the relevant wing side piece 16C protruding, relative to a scale 65 adjustable slide can be operated in a simple manner.

Since apart from the one hinged on the main wing 16 / opening inward Secondary wing 17, a second, outwardly opening secondary wing 17a is / can be attached to a glazing on the main wing 16 can be waived. Single glazings 25, 26 in the two secondary wings 17, 17a are sufficient. Between the two glazings 25, 26 is an approximately 8 cm wide air space, and the special design of the open shaft profiles 60 is from here the ventilation chamber about 40 mm wide and about 40 mm deep with the core arranged in it or with the rotatable one Full length roller accessible. The static effectiveness of the profile walls is only determined by the one used as a locking piece Cover 61 reached in full.

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

In FIG. 7, which corresponds to FIG. 4b of the main patent, the soundproof ventilation is in the "summer" ventilation position. In the case of the lower ventilation unit 18a, the rotatable core 40 connects the air passages with its two air ducts 41, 43 33 on the inside of the window 10b with the air passages 32 to the space between the panes 24, and the core 40 of the upper ventilation unit 18b is in a position in which it is the The space between the panes 24 connects to the outside of the window 10a. The roller blind 19b of the roller blind insert 19B, that is to say the The blind sheet located near the inner glazing 26 is drawn out and, thanks to its special coating, absorbs the through the outer glazing 25 incident solar radiation in such a way that it is converted into heat radiation in the mid-infrared range and, because glass is impermeable to thermal radiation in this radiation area, it is not released to the outside again will. The result is a so-called greenhouse effect, which increases the air in the space between the panes 24.

warms and an additional buoyancy is generated, which for a corresponding ventilation on the inside of the window 10b cares. At the same time, the extended roller blind 19b, which reflects thermal radiation on the side facing the interior Special coating has, in connection with the inner glazing 26, a thermal insulation similar to an inner one Insulating glazing. From the room to be ventilated, the used room air is extracted by the sound insulation ventilation, and also through the extended blind sheet 19b a The inside 10b of the window is heated by the outside of the window 10a existing hot air avoided.

8, which corresponds to FIG. 4c of the main patent, shows a "winter" ventilation position in which the lower ventilation unit 18a the outside of the window 10a with the space between the panes 24 and the upper ventilation unit 18b with the space between the panes 24 connects to the inside of the window 10b. Here is the one too the roller blind 19b located next to the inner glazing 26 is pulled out, so that a winter sunlight from the window outside in the manner just described for the supply is made usable of fresh air to the window inside 10b. A so-called sun trap results. Besides, also serves here the roller blind 19b in connection with the inner glazing 26 as thermal insulation similar to an inner insulating glazing and prevents the transfer of room heat and thus its loss to the outside of the window.

Also in Fig. 9, which corresponds to Fig. 4d of the main patent, is located the sound insulation ventilation is in the ventilation position of FIG. 8, however, it is not the inner roller blind, but the closer to the outer glazing 25 located roller blind 19a of the roller blind insert 19A, the one on both sides Thermal radiation reflective coating has pulled off.

Here, thermal insulation in the manner of insulating glazing is achieved towards the outside of the window 10a, while that of the inside of the window through the inner glazing 26 into the space between the panes 24 to the Inside of the roller blind 19a hits, reflected there, and partly in the form of a heat recovery for the buoyancy of the fresh air supplied in the space between the panes 24 is made usable.

By adjusting the two ventilation units accordingly 18a, 18b of the sound insulation ventilation and by optionally pulling out of the roller blinds 19a, 19b of the two roller blind inserts 19A, 19B are numerous other ventilation positions taking into account the avoidability already described in the main patent condensation on the glazing possible, both with heat recovery and with thermal insulation opposite the transfer of heat or the transfer of cold to the interior of the window or vice versa.
