Description

The object of the invention relates to a ventilation device according to the preamble of Claim 1.

Aero 90 - selbstriegelnde Klapplüftung" der Firma Renson bekannt. Die aus dem Stand der Technik bekannten Lüftungsvorrichtungen bestehen im wesentlichen aus einem schmalen, langgestreckten Gehäuse, welches so bemessen ist, daß es als Teil eines oder statt eines Füllelementes in einen Flügel- oder Rahmenschenkel eines Fensters oder einer Tür einsetzbar ist. Bei dem Einsatz zusätzlich mit einem Füllelement ist die Lüftungsvorrichtung über eine am Gehäuse angebrachte Verbindungseinrichtung einerseits sowohl mit dem Flügel- oder Rahmenschenkel des Fensters oder der Tür verbindbar, andererseits sind Gehäuse und Füllelement miteinander verbindbar. Dabei füllt die Lüftungsvorrichtung einen entsprechend der Abmessungen des Gehäuses angepaßten Spalt zwischen dem Füllelement und dem Flügel- oder Rahmenschenkel aus.Ventilation devices of the aforementioned type are already known, for example from BE 1 008 603 A6, BE 1 010 057 A6 or DE 295 17 175 U1. In addition, generic ventilation devices are also available through the company logo

Aero 90 - self-locking folding ventilation "from Renson. The ventilation devices known from the prior art essentially consist of a narrow, elongated housing which is dimensioned such that it is part of or instead of a filler element in a wing or frame leg of a When using an additional filling element, the ventilation device can be connected to the wing or frame leg of the window or door on the one hand by means of a connecting device attached to the housing, and on the other hand the housing and filling element can be connected to one another a gap adapted according to the dimensions of the housing between the filling element and the wing or frame leg.

The connection of the housing to the filling element takes place in the prior art through a U-shaped profile section which engages around an edge of the filling element. The U-shaped connecting section is rigid and can be used Sealing elements or the like are provided. In the design according to the DE 295 17 175 U1 is also provided that an assembly of Ventilation device optionally on the lower or upper horizontal frame leg can be done in that separate additional rails can be attached to the housing are, which in turn encompass the filler element and thus the upper one horizontal frame leg associated contact edge of the ventilation device for Connection modified with the filler.

In the embodiments of the above-described prior art provided that certain housing sections on the thickness of the filling element are coordinated. Furthermore, it is necessary that the connection of the housing with the Filling element can take place, here also different widths different Configurations of the housing cause.

This results in several versions of the housing and thus the Keep ventilation devices in stock.

The object of the invention is therefore to provide a ventilation device that addresses the Dimensions of the filling element, especially the thickness, can be adjusted and thus allows to use a ventilation device for a variety of filling elements.

The object is achieved by the characterizing part of claim 1.

The measures of the characterizing part can be achieved through several parts of the Adapt the housing edge formed to the thickness of the filling element, see above that the connection of the filling element with the housing or the housing with the Filling element can be easily adapted to the respective installation conditions.

To secure the connection of the profile rail and the intermediate body is included provided that the displaceable profile rail via a positive and / or Non-positive connection can be connected to the intermediate body. Such positive locking or Non-positive connections can be made, for example, by snap-in snap connections easy to manufacture and can after further training if necessary, be permanently secured with an adhesive connection. A a particularly advantageous embodiment provides that the inner profile rail a plastic profile is that the outer rail from an aluminum profile exists, and that the intermediate body is formed from an aluminum hollow profile. This allows a particularly simple and inexpensive manufacture of the Achieve housing components.

It is also provided that the inner rail and the intermediate body together form a mounting bracket, the dimensions of the strength of the Filler corresponds. This allows an assembly of the ventilation device on the Effect wing or frame legs, which essentially that of the filling element. 3 corresponds, since the dimensions of the filling element and the dimensions of the Attachment approach match.

It is also provided that the outer rail is designed as a weather protection profile and is releasably attached to the intermediate body via a snap connection. This leaves the weather protection profile may decrease and at least part of the Ventilation device can e.g. cleaned or replaced. If applicable also an adaptation through different designs of weather protection profiles possible.

Another embodiment provides that the snap connection for fastening the Profile rail on the intermediate body in a U-shaped section open to the outside (or a groove), which opens into the passage opening of the intermediate body.

It is further provided that the outer profile rail designed as a weather protection profile together with the intermediate body essentially two over the entire length of the Ventilation device-forming chambers. These chambers work on one closed or blocked flow path as thermal insulation chambers, since a Air exchange is only possible when the flow path is open.

A disadvantage of the known prior art is that the rigid Connection via a U-shaped grip around the edge of the filling element complicated assembly of the ventilation device together with the filling element necessary makes. During assembly, the filler element may have a large one Dimension and a high weight at the same time with - this filling element over the encircling the edge in a U-shape - ventilation device in the sash or frame to insert. This is particularly difficult if the assembly of the Ventilation device on the lower horizontal frame or wing leg, because the additional profile rails attached via the clamp connections slip could and the sometimes heavy filling element gently into the only slightly larger dimensioned U-shaped receptacle of the housing must be used.

It is therefore provided in a further development that the attachment of the housing to the Filler from an L-shaped leg of the housing and one on the housing attachable bar, which encompass the filling element in a U-shape. The filling element is therefore on an L-shaped leg of the housing, so that there is none closed U-shaped connection on the housing of the ventilation device results. The Ventilation device can therefore first on the wing or frame leg can be created that the filling element in the corresponding free Gap inserted between the wing or frame legs and the ventilation device is, the filling element already on the L-shaped leg of the housing lies on. The housing is then attached to the filling element by the housing attachable bar, through which - in connection with the L-shaped Leg of the housing - the filling element is finally embraced in a U-shape.

This simplification of the assembly results from an arrangement of the Ventilation device on the upper as well as on the lower horizontal wing or Frame legs. In this case, the assembly of the ventilation device can, if necessary the building opening has already been completed, which is particularly the case if sashes or frames that cannot be opened are provided. With these in Windows generally known as fixed glazing are attached to the Ventilation device without a wing profile directly on one of the frame legs, so that before inserting the filler element, attach the corresponding one Frame legs must be made at the building opening.

It is also provided that the L-shaped leg integrally with the housing is trained. This also eliminates additional loosely attached to the housing Profile rails that could possibly prevent assembly.

It is also provided that the bar via a positive connection on the housing can be coupled. This ensures an easy but safe installation of the bar. A particularly simple embodiment provides that the bar one of the housing assigned an undercut groove, extending over the entire length of the bar Has locking hook. You can use the undercut groove and the locking hook an easy to manufacture and yet secure connection of the bar to the housing accomplish.

To avoid a jagged view of the ventilation device, it is also provided that that the bar has a cover web that the housing and / or the groove at least covers areas.

Another embodiment relates to a housing, which consists of an inner and a outer rail is formed, this by a z. B. thermal insulation Intermediate bodies are interconnected. After that, the bar of the inner Profile rail are assigned so that the fasteners for the bar of are easily accessible on the inside, but also have long connecting elements possibly other housing components, which are only on the inner profile rail should be led past, avoided.

An inexpensive and precise production of the bar is guaranteed if this as Aluminum profile is formed.

A particularly advantageous embodiment provides that the bar is flat and applies less to the filling element than the circumferential seal between Filler and wing or frame leg. This arrangement prevents that with the installed ventilation device and the bar attached to it attached between the glazing bead and the filling element or the ventilation device Seal is strongly deformed or even partially or completely if necessary must be eliminated. The seal can therefore continue along its entire length assigned to the corresponding glazing bead and only overlaps the flat applying bar effortlessly, without lifting the seal in one Partial area must be feared due to larger transitions.

It is also provided that the inner profile rail is substantially U-shaped is and encompasses the intermediate body with legs, the legs of the longitudinal contact edges of the filling element and the wing or Form frame legs. This arrangement ensures that the stability of the inner profile rail is additionally reinforced by the intermediate body, so that the Contact edges of the filler the corresponding weight of the filler can transfer easily.

In a ventilation device in which the inner passage opening through a Closure flap is closable, it is also advantageous if the closure flap is assigned to the inner profile rail, the inner profile rail with a longitudinal groove is provided, which has the inner passage opening and which with respect to the Longitudinal central axis of the longitudinal groove arranged and formed symmetrically longitudinal grooves is limited laterally, and that the closure flap in the lower groove is pivotally mounted. This will arrange the shutter causes that little about the interior view of the ventilation devices or the Filling element protrudes and is accordingly easy to clean. At the same time is an easy and simple installation of the flap in the longitudinal groove possible. A development of the above embodiment provides that the Locking flap optionally with one of the, with respect to the longitudinal central axis of the longitudinal groove symmetrically arranged, grooves can be coupled hinge-like. This can be an embodiment be taken, with the flap optionally in one of the two grooves can be fastened, which means that the entire ventilation device without changing the inner Profile rail for installation on both the lower and the upper horizontal Frame leg is suitable. The flap is coupled to the lower groove, see above that a secured opening position of the closure flap by gravity alone is guaranteed.

It is further provided that the grooves are at least partially circular Have cross-section. As a result, in particular in the Closure flap claimed a symmetrical groove in a simple manner Fasten the hose seal without paying particular attention to the orientation.

A particularly advantageous embodiment also provides that the Closure flap carries a longitudinal bearing approach that approximately has circular cross section. As a result, the lower groove forms a bearing for the Closure flap, while according to a further embodiment that of the hinge-like Storage of the flap opposite groove at the same time the recording for forms a sealing hose.

To the section between the tailgate and the longitudinal end of the To be able to complete ventilation device, it is also provided that the longitudinal groove is limited by profile sections that can be coupled to the longitudinal groove or the grooves are. These profile sections serve as end pieces of the longitudinal groove and are after one further configuration on the thickness of the circumferential seal between the filling element and wing or frame legs matched. This ensures that the All-round seal of the glazing beads on the almost flat by the profile sections trained inner visible edge of the ventilation device can rest and itself a closed, little jagged interior view results.

The state of the art according to the company script Aero 90 - Self-regulating flap ventilation "known ventilation devices has a flow path with an elongated flow cross-section, which is formed by a narrow, elongated housing of the ventilation device. A movable, flow-defining elastic element is arranged in the housing, that due to its fastening or its own Elasticity and the flow force determined by the pressure difference between the outside and inside of the building assume an equilibrium position and thereby regulate the flow cross-section in such a way that this changes approximately in inverse proportion to the pressure difference.

Similar ventilation devices of the aforementioned type are already known, for example by DE 2118030 B1 or GB-PS 1176314.

In these known ventilation devices it is provided that the element in the ventilation cross section is taken hanging or in the case of DE 2118030 B1 known is guided laterally. In the design according to GB-PS 1176314 results thereby a certain height of the ventilation device, since the elastic element plus an at least existing ventilation gap in the ventilation cross section must be provided. This takes place in the configuration according to DE 2118030 B2 Fastening, however, the longitudinal ends of the ventilation device, which the length-dependent provision of such a ventilation device is disadvantageous.

From the company script Aero 90 - self-locking folding ventilation "from Renson, an arrangement of the element according to GB-PS 1176314 is known. In addition, a closure flap is provided in the interior of the ventilation device, through which the ventilation cross section can be completely closed.

It is also disadvantageous here that due to the arrangement of the closure flap and the elastic element is a comparatively large height, what when used as part of or instead of a filling element in a wing or Frame leg of a window limits the usable window area.

The arrangement of the element results in a space-saving arrangement full mobility of the element ensured without the function of the Element is affected. It is also of particular advantage that the chamber, in which the element is arranged, formed by two components of the housing, so that the element despite the arrangement in the chamber at least before the assembly of the Housing is accessible.

Furthermore, the invention provides that the outer rail together with the Intermediate body forms a second chamber in the flow direction from the Looking inside the building - in front of the element.

This allows an accurate and targeted flow within the housing effect that ensures a defined and effective taking of the element.

It is then provided that in the second chamber along the outside open passage opening of the outer profile rail, a second element is provided, which blocks the passage opening when there is no pressure difference Closes flow cross section or a flow directed from the inside to the outside. This simple measure achieves a so-called diode effect, in which the Flow direction inside the ventilation device only from the outside of the building the inside of the building. Such restrictions of Flow directions are particularly advantageous when separate Exhaust devices already exist. Furthermore, this arrangement achieves that with a blocked or closed flow cross-section, in which none There is a pressure difference between the inside of the building and the outside of the building the ventilation device itself is closed. This can be the case, for example be when the ventilation device special locking devices, for. B. flaps or the like, are provided by which the flow cross section is shut off can be. Then through the installation of the second element in the second chamber these sealed to the outside of the building, so that in the second chamber standing air layer arises in connection with that also in the first chamber standing air layer to a substantial increase in the thermal insulation of the whole Ventilation device contributes.

1 shows a ventilation device 1 on a wing 2 of a window or a door, in the external view of the wing 2 shown in FIG. 1, only an external one Profile rail is visible, as will be explained more clearly later. The wing 2 is with provided a filler 3, the z. B. from an insulating glass pane, a panel or similar exists. From the inside view of the wing 2 shown in FIG can be seen that the filling element 3 attached along the edge from the inside and visible strips, the so-called glass strips 4, is encompassed.

The structure of the ventilation device 1 is shown in FIG. 3. From this it can be seen that the ventilation device 1 in a gap between a wing leg 5 and the Filling element 3 is used. The housing 6 consists essentially of one inner and an outer profile rail 7, 8, which by an intermediate body 9th are interconnected. The intermediate body 9 is also a profile rail formed and has at least one passage opening 10, the one Flow cross section within the elongated housing 6 opens. In the outer Profile rail 8 is also provided a passage opening 11, which together with a passage opening 12 a flow path to the outside of the building 13 Open inside of building 14.

The filling element 3 is the ventilation device 1 on a designated Attachment section assigned, the attachment of the housing 6 to the Filling element 3 is formed on the one hand from an L-shaped leg 20 of the housing 6 and on the other hand by a bar 21 which can be fastened to the inner profile rail 7, which together encompass the edge 22 of the filling element 3 in a U-shape.

The bar 21 is, as is particularly clear from FIG. 3, via a locking hook 23 connectable to the inner profile rail 7, the latching hook 23 being perpendicular to the Level of the bar 21 rear projecting profile web 24 is formed, which over the entire length of the strip 21 is sufficient. While the bar 21 on the filling element 3 associated end carries a seal 25, which is close to the profile web 24 Longitudinal edge formed as a cover web 26, which is also on the inner profile rail 7 abuts and the provided for cooperation with the locking hook 23, at least undercut groove 27 completely covered. The bar 21 is dimensioned so that the contact edge 28 of the filling element 3 assigned to the edge 22 on the Ventilation device 1 is completely covered.

Through the profile web 24, the bar 21 receives an additional, perpendicular to its plane acting reinforcing web, which makes it difficult to deform or twist the bar 21. There is also an additional by the overlapping of the glass strips 4 on the strip 21 Attachment of the bar 21 ensures that it no longer from the groove 27th can be removed.

The bar 21 is designed overall as a relatively flat, but slightly curved aluminum profile rail, so that the bar 21 can easily cooperate at its longitudinal ends with the seals 29 of the vertical glass strips 4, without the seals 29 or the glass strips 4 removed partially or completely Need to become.
Due to the bar 21, which is only flat on the whole, an almost uninterrupted contact of the seal 29 with the filling element 3, the housing 6 and the fastening section between them is also ensured. In the case of a solid bar 21, the seal 29 would otherwise have to be lifted off, at least in the transition area to the filling element 3. In order to support a uniform contact of the seal 29, it is provided that the bar 21, which is only slightly bulky, runs flat on its leg 30 assigned to the filling element 3.

The contact edge 28 of the filling element 3 is equally from the Intermediate body 9 and the inner profile rail 7 are formed. The L-shaped leg 20 is formed in one piece with the intermediate body 9.

The strip 21 is namely like the inner profile rail 7 and the intermediate body 9 dimensioned according to the width of the filling element 3 and thus almost completely fills the gap otherwise available to the filling element 3.

As is also clear from FIG. 3, the inner profile rail 7 is in the essentially U-shaped, with the horizontally extending U-legs 31, 32, means 33 for connecting the intermediate body 9 to the inner profile rail 7 are provided, which will be explained in more detail below. The intermediate body 9 and the inner profile rail 7 form on the one hand already mentioned contact surface 28 for the Filling element 3, but on the other hand also a contact edge 34 for attachment to the To ensure glass rebate 35 of the wing leg 5.

When installing the filling element 3 is usually between the glass rebate 35 and the filling element 3, a spacer block 36 is provided for the precise alignment of the Wing 2 to filler 3 is used and a slight correction of the shape of wing 2 allows. The spacer blocks 36 are introduced before assembly the glazing beads 30, with possible shape deviations of the wing by different distance blocks 36 are compensated.

This method, generally known as padding, is carried out using the method shown in FIG shown ventilation device 1 and the filling element 3 in the known manner and Way performed.

The ventilation device 1 is installed by inserting the ventilation device 1, if necessary together with the spacer blocks 36 in the glass rebate 35 Filling element 3 also inserted, between the filling element 3 and the Ventilation device 1 also one or more spacer blocks 37 can be provided. Then the filling element 3 and the ventilation device 1 are fixed the circumferential glass fold 35 by adding dimensionally coordinated spacer blocks 36 between the glass rebate 35 and the contact edge 34 on the one hand and between the Filling element 3 and the glass rebate 35 of the adjacent wing or frame legs on the other hand. Is the filling element 3 together with the ventilation device 1 free of play the revolving glass rebate 35 is added, the bar 21 to cover the Edge 22 or the contact surface 28 between ventilation device 1 and filler element 3 appropriate. Finally, the glass strips 4 on the wing or Frame leg 5 attached, in the illustrated embodiment by a Snap connection are attached. The ventilation device 1 behaves accordingly when installing similar to the installation of a filling element 3 and no further is required or additional handling of rails or the like that between Filling element 3 and housing 6 must be inserted. The ventilation device 1 and the filling element can be handled almost completely separately from one another.

As is apparent from FIGS. 3 and 4 and explained with reference to FIG. 4, the Flow cross section can be closed via a closure flap 40. To do this, the inner one Profile rail 7 has a longitudinal groove 41, which with its vertical groove bottom of the inner passage opening 12 is provided with respect to that indicated in FIG. 4 Longitudinal central axis 42 of the longitudinal groove 41 is symmetrical. On the longitudinal groove 41 are grooves 43, 44 running along their longitudinal edges, at least one have partially circular cross-section, preferably more than semicircular. The Closure flap 40 carries a bearing projection 45 running over its entire length, which also has an approximately circular cross section. The closure flap 40 can be selected with one of the grooves 43 or 44 couple hinge-like, as can be seen from the comparison of FIGS. 3 and 4. In the 4 is the ventilation device 1 on a lower horizontal Wing leg 5 '(Fig. 2) arranged. As a result, the filling element 3 sits above the Ventilation device 1, and the inner rail 7 is to the embodiment of FIG Used rotated by 180 °. However, the closure flap 40 should continue to be the same Be usable and due to gravity automatically in the open position stop. Therefore, the bearing projection 45 of the closure flap 40 can optionally the groove 43 or groove 44 are coupled in a hinge-like manner, each of which is not due to the Bearing approach 45 filled groove is filled by a sealing hose 46. The the hinge-like mounting of the closure flap 40 opposite groove (e.g. groove 43 in Fig. 4) therefore forms a receptacle for the sealing hose 46 and ensures reliable sealing of the passage opening 12 by engaging the closure flap 40 on the sealing tube 46.

It is easy to understand that the closure flap 40 is made slightly shorter must be as the ventilation device 1, the length of which is essentially the width of the Filling element 3 corresponds. The closure flap 40 must not pass through the glass strips 4 be overlapped, otherwise an opening would no longer be possible. Therefore are laterally on the flap 40 also with the grooves 43 or 44 can be coupled, rigid Profile sections 47 are provided which close the longitudinal groove 41 and flush one Ensure completion of the inner rail 7. This is particularly the case 5 can be seen in the isometric representation. The profile section 47 is made essentially consisting of a flat strip which corresponds to the one Bearing projection 45 of the closure flap 40 has a fastening projection 48.

Characterized in that the profile sections 47 a flush surface of the inner rail 7 and ensure the longitudinal groove 41, it is also ensured that the circumferential seal 29th the glazing beads 4 without interruption and without the possibility of lifting off the Ventilation device 1 is present.

3, 4 and 5 also show that the closure flap 40 next to the bearing shoulder 45 has an operating lever 49 which opens and closes the closure flap 40 by an operator. On the back is the flap 40 a web 50 from that with a fastener fastened in the passage opening 12 51 cooperates in the closed position. For this purpose, the closure member 51 has a elastic latching hook 52, with the web also designed as a latching hook 50 can enter into a snap-lock connection. The fastening of the closure member 51 in the passage opening 12 is likewise carried out by a snap-snap connection, here with the longitudinal edges 53, 54 of the passage opening 12 cooperating locking hooks 55, 56 are provided. This is the passage opening 12 formed by vertically aligned side by side elongated holes in their Width are coordinated with the closure member 51. Possibly. can a flap 40th also several adjacent closure members 40 can be assigned.

The length of the locking hook 52 or its protrusion over the longitudinal groove 41 decides thereby - in cooperation with the web 50 - via the contact pressure of the Closure flap 40 on the sealing tube 46. It can therefore also be provided that by a possibly extended locking hook 52 on the closure member 51 a Desired permanent opening position of the closure flap 40 is achieved completely closing makes impossible. This can be useful, for example, if constant permanent ventilation of the inside of the building 14 is absolutely necessary or the residents are to be induced to have permanent ventilation. This can be the reason also the operation of combustion plants or similar be a constant fresh air supply make necessary. The locking member 51 can be connected via the latching snap connection if necessary, be replaced later.

As is apparent from FIGS. 3 and 4 and has already been mentioned, the Ventilation device 1 both for installation on an upper horizontal wing or Frame leg 5 suitable (Fig. 3), as well as for installation on a lower horizontal wing or frame leg 5 'provided (Fig. 4). Find in essentially the same components (7, 8, 9) use, the intermediate body 9 and the inner profile rail 7 are retained in both installation situations and can only be used rotated by 180 °. The outer rail 8 is, however the installation on the upper horizontal wing or frame leg 5 compared to Installation on the lower horizontal wing or frame leg 5 'with a light modified form.

So that the intermediate body 9 can continue to be used in the present form can, the outer rail 8, which is designed as a weather protection profile, with this releasably connected via a latching connection 60 (FIG. 4). The latching connection 60 is located here in a U-shaped outwardly open section 61 (or a groove), which in its Has floor in the passage opening 10. The latching connection 60 is then over internally facing legs 62, 63 of the outer profile rail 8 formed in engage longitudinal undercut grooves 64 on the intermediate body 9 and form the side walls of the flow path. The legs 62, 63 are aligned with their insides essentially with the passage opening 10, while the lower Leg 63 has the passage opening 11.

Via the snap connection 60, the outer profile rail 8 can therefore correspond to the Install the installation conditions either for the respective installation location. At the same time can by the releasable attachment of the outer rail 8 cleaning at least the outer flow path can be made easily. The Legs 62, 63 form an open U, which after removing the outer Profile rail is easily accessible from the inside. At the same time, the legs 62, 63 together with the intermediate body 9, a first chamber 65 and the L-shaped Leg 20 and a matching profile section 66 (in Fig. 3) or 67 (in 4) a second chamber 68 or 69. The chamber 69 is located in that in FIG. 4 Installation example shown above the flow path and is not by this permeated. 3, on the other hand, chamber 68 forms one Part of the flow path and closes essentially below the Passage opening 11, and in turn has a further passage opening 11 '.

It is provided in each case that the wing or frame leg 5, 5 ' facing profile sections 70 of the outer rail 8 each spaced from the outer peripheral edge 71 of the wing or frame leg remain to a Cleaning the peripheral edge 71 and the outer rail 8 or loosening the To allow snap-in connection. The chambers 65 and 68 each extend over the Entire length of the ventilation device 1.

It is further provided that the intermediate body 9 in turn has two chambers 72, 73 forms, as can be seen in FIGS. 3 and 4.

These chambers 72, 73 serve essentially for thermal insulation between Building exterior 13 and building interior 14.

As has already been indicated with reference to FIG. 3, the intermediate body 9 and the inner profile rail 7 can be connected to one another via means 33. It is provided that the inner profile rail 7 can be moved transversely with respect to the intermediate body 9 is arranged. The displaceable arrangement is a Form-fit connection or the like can be secured so that the set position of Intermediate body 9 and rail 7 can be fixed. In the embodiment according to Fig. 6 this can be done, for example, by a suitable adhesive connection between the Intermediate body 9 and the profile rail 7 take place on the contact surface 75. If necessary, the contact surface 75 of the U-legs 31, 32 and the Intermediate body 9 are additionally provided with locking elements or the like cause a positive connection.

In the embodiment of FIG. 3, however, is on the inner rail 7 groove 77 delimited by latching webs 76 for receiving a barbed one Bridge 78 attached. The groove 77 is open towards the intermediate body 9, so that the inner rail 7 and the intermediate body 9 relative to each other without problems are movable.

Due to the relative displacement of the profile rail 7 relative to the intermediate body 9 the width of the contact edge 28 can be adapted to the thickness 79 of the filling element 3. It will usually different strengths of the in different installation situations Filling element 3 used, for example if an insulating glass pane with special thermal or burglar-resistant design should be used. Here can vary the thickness 79 of the filling element 3 in a certain range, what can be compensated for by the relative displacement.

For the design of the locking connection but also for a suitable thermal insulation of the entire housing 6, it is advantageous if the inner profile rail is made of a plastic profile, while the outer rail 6 consists of a Aluminum alloy is manufactured. The intermediate body 9 is as Hollow aluminum profile formed, making the chambers 72 and 73 easy to manufacture to let. At the same time, the load-bearing capacity of the construction is significantly increased because of the torsion-resistant and favorable in terms of its section modulus of the intermediate body completely between the wing or frame leg 5.5 'and the Filling element 3 is added.

To attach the housing 6 to the wing or frame leg 5, 5 'is also provided that the inner rail 7 and the intermediate body 9 together a Form attachment lug 80, the dimensions of the thickness 79 and the width the filling element 3 corresponds. The attachment lug 80 is used for the system the glass rebate 35 or on the spacer block 36, as in particular in FIGS. 3 and 4 is recognizable. The attachment projection 80 forms the on its outer edge Contact edge 34, which is assigned to the spacer block 36.

3, 4 and 6, the contact surfaces 75 and the grooves 77 are so designed that the maximum displaceability of the inner rail 7 compared the intermediate body 9 is limited. In the embodiment according to FIG. 6, the Fastening approach 80 a web 81 is provided, which with the U-leg 32 of the inner Profile rail 7 cooperates in the displacement end position. In the case of the filling element 3 associated contact edge 28, the L-shaped leg 20 forms a contact edge for the lower U-leg 31.

3, however, it is provided that the locking webs 76 in the Initiate the final displacement position on the intermediate body 9.

In the minimally adjustable thicknesses 79 of the filling element 3 shown in FIGS. 3 and 6 the arrangement or length of the U-legs 31, 32 is chosen so that between the Intermediate body 9 and the inner rail 7, a chamber 82 remains, which to a insulating air cushion between the intermediate body 9 and the inner Profile rail 7 leads.

It is also worth mentioning that the attachment projection 80 has a height 83, which is dimensioned essentially so that the seals 29 of the upper horizontal Glazing beads 4 reach right up to the longitudinal groove 41. In connection with the bar 21, the cover web 26 and the closure flap 40 is almost a perfect coverage 40 of the inner rail 7 causes. This eliminates any necessary color adjustments to the inner rail 7, the - how has already been stated above - is produced as a plastic profile. A color Adjustment is therefore only on the closure flap 40, the profile section 47 and the Strip 21 necessary, while the profile rail 7 made of black plastic, to match the seals 29, which are usually colored black, can be carried out. The function of the ventilation device 1 will be explained with reference to FIG. 6. The Ventilation device 1 is intended to automatically ventilate the inside of the building 14 and therefore has, in a manner known per se, an elastic element 90 which in the Flow cross section or flow path 91 is arranged.

The element 90 is designed and arranged within the housing 6 that it can be moved by a flow along the flow path 91. Here the length of the element 90 corresponds almost to the outer profile rail 8. Depending on Volume flow that depends on the pressure difference between the outside of the building 13 and the inside of the building 14, the element 90 is deflected so far that the Leg 92 narrows the flow cross-section and - with increasing Volume flow - abuts web 93 of outer profile rail 8. The available free flow cross section in an almost inverse proportion to the Height of the pressure difference changed.

As can be seen from FIG. 6, the element 90 is in one piece with the element 90 executed V-shaped fastening section 94 in a complementarily shaped Groove 95 recorded and inclined to the vertical, executed and takes an angle of about 30 ° to 45 °. The element 90 becomes in the chamber 65 added by the intermediate body 9 and the outer profile rail 8 is formed together. As a result, the element 90 is when the profile rail 8 is not mounted accessible and can be easily mounted on this in the groove 95. Because of the inclination of the element 90 a comparatively space-saving position is achieved, so that the Chamber 65 can be kept very small in its vertical extent. The overall necessary overall height of the housing 6 is reduced accordingly.

The element 90 consists of the fastening section 94 and the leg 92 a section 96 which forms a film hinge and very much in comparison to the leg 92 is thin. This makes the necessary mobility of the element 90 ensures that, for example, by extruding a suitable rubber or Plastic material can be produced. 3 and 4 is the Section 96 is short and additional wings are on the leg 92 attached that in the equilibrium position, with the flow cross section almost is fully released, cooperate with the housing 6 and the Limit end pivot positions.

In the embodiment according to FIG. 6, this is done by the webs 93 and 97, the Element 90 with the flow cross section on web 97 almost completely released supports, which spaced the element 90 from the passage opening 11.

A second element 98 is fastened to the passage opening 11 '. This element 98 closes in its initial position in which there is no volume flow along the Flow path 91 is conveyed, the passage opening 11 '. With a volume flow to the inside of the building 14, the flat against the profile section 66 and on its longitudinal edge 99 on this fastened element 98 on the longitudinal edge 100 raised, as indicated in FIG. 6.

The second element 98 therefore causes on the one hand that no flow from the Building inside 14 can get outside. On the other hand, the Passage opening 11 'in the absence of a pressure difference, blocked Flow cross-section or a flow directed from the inside to the outside closed, for example with a closed flap 40, being about the second element in the chambers 65, 68 a standing and by the Building outside 13 separate air layer is created, which leads to an increased Thermal insulation of the entire housing 6 leads. The second element 98 thus effects a diode effect in which a flow can have only one direction, and at the same time improves the thermal insulation of the ventilation device 1. Such Limitations of the flow directions are particularly advantageous if there are already separate exhaust air devices. By in just one The direction of the standing volume flow can also be significant Simplified design of the first element 90 take place because a control of the Volume flow to the outside of the building 13 is omitted and at the same time corresponding Stops or the like to avoid influencing the first element 90 can be omitted.
