Abstract

In a sealing arrangement for glass panes in wooden window or door leaves, in which the glass pane arranged in the window frame is supported on the outside of the frame against a glass rebate chamfer and on the inside of the frame against a glass retaining strip, while interposing an elastic strand seal in each case, the inside of the glass rebate chamfer also facing its frame opening is provided with an all-round web projecting there and over which is slipped a profile projection provided on the outer strand seal and which completely engages over the same in such a way that it also elastically presses against the outer face of the all-round web which is remote from the glass pane. The inner strand seal has a banana-shaped sealing section whose convexity, on fitting, is directed towards the glass retaining strip and is braced between the latter and the glass pane.

Description

The invention relates to an arrangement for sealing glass panes in window or door sashes made of wood, in which the glass pane arranged in the casement frame is supported on the outside of the frame against a glass rebate bend and on the inside of the frame against a glass retaining strip with the interposition of an elastic strand seal.

When designing wooden window glazing, it was previously known to use elastic putty between the outer surfaces of the window panes to be glazed and the inner surfaces of the associated glass rebate bend or glass retaining strip, which had to be highly adhesive because of the desired good sealing effect. To apply such putties, however, it was necessary to remove them from cartridges, tubes or similar. in the gap between the surface of the glass sheet and the surface of the inside of the glass facing Press in the glazing rebate bend or the glass retaining strip. However, the surface of this kit layer introduced in this way also had to be smoothed in order to achieve a clean appearance of the kit layer in the finished frame. In practice, however, it could hardly be avoided that the glass pane and / or the window frame were smeared by the putty, such smearings then being relatively difficult to remove. In addition, it could happen that if the inner layer of the kit layer was not carefully peeled off, leaks would occur due to voids which could jeopardize the desired sealing effect. Should it be necessary to replace the glass pane with such wooden window glazing, then relatively complex processing steps were necessary: because the entire frame is glued to the inside of the putty joint, so that after removing the pane previously used, it first had to be laboriously cleaned, for example by means of a knife or similar in order to remove the sealant that is still present. However, it could also happen that glass breakage occurred when the existing window pane was removed, if the sealant was not removed with sufficient care and the glass was still held in its position somewhat by kit remnants despite the putty being removed.

Instead of using elastic putties, attempts have already been made to use prefabricated sealing profiles. In the known sealing profiles used for this purpose, however, there was a need to provide cutouts or grooves on the surfaces of the glass retaining strip or the glass rebate bend facing the glass pane, which in turn brought the risk of undesired moisture ingress into such depressions. In this case, however, the penetrated moisture could no longer be removed, which leads to moisture in the wood and thus to the occurrence of fungus Destruction of the wood and other adverse consequences.

A profile seal is known from DE-U-82 15 352, which does not require the penetration of such cutouts or grooves in the glass retaining strip or the glazing rebate bend. However, this known sealing profile is only suitable for the inside of the window, thus for insertion between the window pane and the glass retaining strip, since it does not hold automatically and would otherwise fall out before the pane is installed. However, even with this known profile seal, it is not necessary to make a groove, but it does require the use of a back milling in the glass retaining strip. This in turn results in a relatively high amount of work when producing the glass holding strip. With a sealing arrangement that uses such a profile seal on the inside of the window, the tolerance compensation is satisfactory, but not always sufficient when larger tolerances occur.

Proceeding from this, the invention has for its object to improve an arrangement for sealing glass panes in window or door sashes of wood of the type mentioned that the need for the application of any undercuts, grooves or other recesses on the surfaces of the glass retaining strip facing the window pane and the glass rebate folding is completely eliminated, at the same time always. an excellent and reliable sealing effect against moisture is guaranteed and a particularly simple and quick assembly or removal of the pane is possible at any time.

According to the invention, this is achieved in a sealing arrangement of the type mentioned at the outset in that the glass rebate fold on its inside facing the frame opening with a circumferential web projecting there is provided, over which a profile projection attached to the outer strand seal, which completely engages over the circumferential web, is slipped over in such a way that it also resiliently presses onto the outer surface of the circumferential web facing away from the glass pane, and that the inner strand seal one in the relaxed state in Cross section has an approximately banana-shaped sealing section which is aligned with its curvature towards the glass retaining strip in the installed state and is clamped between the glass retaining strip and the glass pane in such a way that the curvature rests against the glass pane on its rear side at least along a partial section of its rear surface. The sealing arrangement according to the invention enables extremely simple and rapid installation or disassembly of such wooden window glazings without the need for specially trained personnel. The outer sealing profile is first arranged on the window frame with the glass rebate bend, in that its projecting and circumferential profile projection is put over the corresponding circumferential web on the glass rebate bend. In this way, an impeccable fit and proper mounting of the profile on the glass rebate bend is initially achieved, although the window pane is not yet installed. If the outer extruded sealing profile is installed in the frame in this way, the window pane to be sealed is then simply pushed into the frame (the term “window pane” or “glass pane” of course not being limited to the use of a single pane, but rather the pane to be inserted). Should refer to the installation unit as a whole, thus also includes the case of multiple glazing or insulating glazing, which consists of different individual panes). After the glass pane has been pushed in, only the glass retaining strip is then attached and the inner profile seal with its in the gap formed between the glass retaining strip and the inner surface of the window pane Banana-shaped sealing section pressed in from above. The banana-shaped curvature of the inner strand seal enables even relatively large tolerances to be compensated for without problems, since such a banana-shaped curved sealing section has a relatively large lateral protrusion, which is then reduced to the size of the gap when it is introduced into the gap between the pane and the glass holding strip. The circumferential profile projection arranged on the outer profile, which from the inside of the glass rebate folds encompasses and projects behind the projecting circumferential web ("nose") from the inside out, not only brings the fastening effect already mentioned, which thus facilitates the assembly of the overall arrangement , but also prevents undesired moisture penetration in a particularly effective manner. Because for the penetration of moisture, it would be necessary that moisture could penetrate between the elastically pressed profile projection and the circulation web, which in view of the small dimensions of such a web, the relative contact pressure between the elastic profile projection and the surfaces of the circulation web, and taking into account the repeated use considerable change in direction, which inevitably results from the outer contours of the small circular web profile, is almost impossible. In such a way, the moisture would also always have to overcome an upward surface between the elastically pressed profile and the glass rebate bend, thus penetrating "uphill" on a route between an elastically pressed and a fixed part, which likewise almost completely prevents moisture from entering. The mutually adapted design of the outer circumferential web and the projection that completely overlaps and encompasses it on the sealing profile thus results in a combinatorial effect both with regard to easier installation (holding effect of the installed seal on the glass rebate bend without an inserted glass pane), and also with regard to a particularly effective prevention of the penetration of moisture (excellent sealing effect), which is particularly important when sealing panes in wooden windows or wooden doors (moisture, fungus formation). The commonality of the features according to the invention achieves the object on which the invention is based in a surprisingly simple and effective manner. Here, the interaction of the inner seal with a banana-shaped curved sealing section and the mentioned outer seal in its special design, as well as the interaction between the outer seal and the circumferential web on the glazing rebate fold, complement one another to a successful construction of the overall arrangement, whereby the interaction of all the individual features is only the desired overall effect of a particularly simple Construction - with quick and easy assembly, excellent sealing effect, best tolerance compensation and excellent functionality.

An advantageous embodiment of the sealing arrangement according to the invention is that the profile projection on the outer strand seal engages around the circumferential web (seen in cross section) essentially in a U-shape, which is not only a simple design, but also leads to a particularly favorable sealing and holding effect .

A particularly favorable pressing behavior of the elastic profile projection with respect to the outer surfaces of the circulating web can be achieved in that the profile projection overlapping the circulating web (again seen in cross section) is of essentially the same thickness over its entire length. This ensures that the profile projection can still be pressed against the outer surface of the circulating web in the region of its free end with a relatively good elastic contact force.

A further improvement in the sealing effect can be achieved in that, in a sealing arrangement according to the invention, the profile projection is provided with projecting longitudinal ribs on its sides facing the circumferential web. With this design, when the profile projection is pressed elastically against the circulating web at the tips of the longitudinal ribs when the same pressure peaks are pressed, which, particularly in the case of the arrangement of several such longitudinal ribs, provide particularly favorable support for the penetration of moisture.

Another preferred embodiment of the sealing arrangement according to the invention also consists in that the outer strand seal on its outer surface facing the glass rebate bend (thus in the area of the sealing gap between the glass pane and glass rebate bend) is provided with projecting longitudinal ribs: this allows an increased holding effect also within the sealing gap and additionally achieve an improved sealing effect against the penetration of moisture from outside.

In the case of the aforementioned attachment of longitudinal ribs, it is particularly advantageous if such longitudinal ribs are sawtooth-shaped in cross-section, with, again preferably, these longitudinal ribs (viewed in the longitudinal direction of the sealing profile) being arranged in a zigzag shape. Such longitudinal ribs are also advantageously arranged parallel to one another.

Another preferred embodiment of the sealing arrangement according to the invention is that the profile projection completely covers the peripheral web on the outside thereof. This means that the circumferential web projecting from the glazing rebate bend as a whole and, also on its side lying on the outside of the glazing rebate bend, is completely covered or covered by the profile projection, thus the entire outer contour of the circulation web from the profile projection in the form of an overall elastically pressing "cap" is covered.

A further improvement of the sealing effect on the outside of the window can be achieved in that a sealing lip directed from the strand seal against the glass pane and pressed obliquely against the glass pane in the installed state is additionally provided in the foot region of the profile projection. is. Thereby, the location of the outer Stran is substantially ^g addressed seal, outside of the profile projection protruding from the out according to the coverage of the circulating web: therefore, herein, the outwardly projecting lobe in an inward, ie projecting to the outer surface of the window and there (as a result elastic bending) pass over the obliquely pressed sealing lip, which not only allows an improved sealing effect to be achieved there, but also gives a pleasing appearance (the profile projection on the outside that covers the circumferential web in a cap-like manner continuously changes into a sealing lip directed towards the inside) .

Another very particularly preferred embodiment of the sealing arrangement according to the invention also consists in that the outer strand seal on its inner side facing the glass pane, in addition to elastically deformable sealing lips, also has at least one projection as a stop for the glass pane, again, preferably, two such projections serving as stops being provided are one of which (seen in cross-section of the seal) is located approximately at the height of the profile projection for covering the circulating web on the glass rebate bend and the other in the region of the other end of the profile seal: this makes it easy to achieve the great advantage that not only when inserting the glass pane during assembly on the outside there is a precisely defined assembly stop for the glass pane, but moreover this also prevents the remaining ones from the outside String seal against the surface of the glass pane sealing lips could be deformed too much, so that no undesirable crushing of the sealing lips or the like can occur, which increases the sealing effect.

A further preferred embodiment of the sealing arrangement according to the invention also consists in the fact that the inner strand seal has a sealing projection on its side facing the glass holding bar, which in the installed state is pressed against and covers the inner edge of the glass holding bar facing it. This simple design of the inner strand seal ensures that when it is installed, namely if it is inserted from above into the open sealing gap between the glass pane and the glass retaining strip, this sealing projection provides a type of "stop" in such a way that it is not accidentally is inserted too deep into the sealing gap. By covering the inner edge of the glass retaining strip there over this sealing projection, an improved sealing effect on the inside of the room is also achieved at the same time.

A further advantageous embodiment of the sealing arrangement according to the invention also consists in the fact that the inner strand seal has an inner sealing lip in the extension of its banana-shaped sealing section, the inner surface of which faces the glass pane in the installed state is pressed against the glass pane over its entire length and the outer surface of which merges with that of the sealing projection. Also thereby, not only is a particularly gefälli ^g e optics reaches the entire upper slot cover on the inside of the wooden window or door of the timber, but in addition also a very effective improvement of the sealing effect on the indoor side.

A further advantageous embodiment of the sealing arrangement according to the invention consists in that hollow chambers extending in the longitudinal direction of the strand are provided within this inner sealing section in the inner strand seal in the region of the banana-shaped sealing section. As a result, the overall elasticity of the banana-shaped sealing section can be influenced to the desired extent, with an appropriate arrangement of such internal cavities also making it possible to improve the tolerance compensation.

In general it should be noted that the tolerance compensation of the complete sealing assembly can be carried out exclusively via the inner strand seal in the formation of the outer strand seal ^g with on its side facing the glass pane inside provided Profilvorsprün s which are to serve as stops for the glass sheet, because due to the attacks the pressing position of the glass pane is precisely defined on the outer strand seal and any existing tolerances occur exclusively at the inner sealing gap between the glass pane on the inside of the window and the glass retaining strip, so that they can only be compensated for by the inner strand seal. Particularly in view of this, the banana-shaped design of the sealing section on the inner strand seal used according to the invention proves to be particularly suitable for compensating for the tolerances that occur there. In this case, however, achieved by this sealing profile not only a tolerance compensation with regard to the sealing function, but also a tolerance compensation of the elastic tensioning of the window pane reaches respect within the overall arrangement between the two Strangdichtun ^g en, wherein the desired fixed position of the glass pane is fully assured. The special design of the inner strand seal thus includes within the overall arrangement the effect of tolerance compensation both with regard to the sealing function and with regard to the bracing and holding effect for the glass pane to be assembled.

A further preferred embodiment of the sealing arrangement according to the invention also consists in that outside the banana-shaped sealing section on the inner strand seal in the end region of the strand seal covered by the glass retaining strip, additionally obliquely projecting sealing lips are pressed against the inner surface of the glass retaining strip, whereby the overall sealing effect in particular improved, but certain improvements also occur with regard to the holding effect exerted on the pane.

A further advantageous embodiment of the invention consists in that stiffening inserts are attached in the area of the banana-shaped sealing section within the inner strand seal, so that - with a suitable arrangement of such stiffening inserts as well as with the use of suitable stiffening materials - overall a certain "spring characteristic" when elastically squeezing the Can reach sealing section.

In the sealing arrangement according to the invention, the outer strand seal is furthermore particularly advantageously designed in such a way that, in the relaxed state, it has a profile central web, at one end of which (seen in profile cross section) a profile projection is provided on one side, which is inclined at an acute angle to the profile. Center bar protrudes and at its end is provided with a short nose protruding towards it approximately at right angles to the center bar, that the profile projection in its foot area at the center bar merges into a sealing lip which projects on the other side of the center bar in an extension of the profile projection , on this side directly below the sealing lip and at the other end of the agent A protrusion provided with a stop surface for the glass pane and a further sealing lip projecting obliquely at an obtuse angle to the central web are arranged on each of these projections. This configuration of the outer strand seal represents a particularly favorable sealing profile shape with regard to the use of such a strand seal within a sealing arrangement according to the invention, which not only has the abovementioned stops for the glass pane, but also additionally ensures through its special design of the profile projection when installing the circulating web to be covered by the profile projection is always contacted by the profile projection under elastic pretension.

The sealing arrangement according to the invention thus results from a successful combination of individual elements not only an overall simple structure with excellent long-term sealing effect, but also an equally simple installation or removal for the window pane, without the need to employ particularly qualified specialist personnel or to carry out lengthy work. A practical experiment has shown that the sealing arrangement according to the invention can be assembled or disassembled in a remarkable speed that has not been achieved by previously known sealing arrangements. The advantage of using prefabricated sealing profiles is combined with the advantage of particularly clean workability during assembly, as well as repair glazing that can be carried out at any time without problems and with little effort, advantages that have not been achieved so far with wooden window glazing.

The invention is explained in more detail below in principle on the basis of the drawing. Show it:

• Figure 1 is a basic sectional view of a sealing arrangement according to the invention in the installed state in a wooden window.

• Fig. 4 shows an inner strand seal according to the invention (shown in cross section and in a relaxed state).

1 shows a basic illustration of a cross section through a sealing arrangement according to the invention in the installed state in a wooden window: a window frame (casement frame) 1 is provided on its outside with a projecting glass rebate bend 2. A glass pane assembly 3 is accommodated within the casement 1, which in the example shown is designed as double insulation glazing with two glass panes 3. This double insulation glazing 3 is supported by blocks 5 with respect to the frame 1.

An outer strand seal 8 is arranged between the insulating glazing 3 and the projecting glass rebate bend 2 and an inner strand seal 9 between the insulating glazing 3 and the glass retaining strip 4. Here, the glazing 3 protruding profile stops 15 and 26 is supported with its lying on the window outside glass surface opposite to the outer strand seal ^p rofile 8 inward to the glass cover 3, so that their position relative to the Glasfalzabkantung 2 by the stops of the outer strand seal 8 pretty is precisely defined.

The outer strand seal 8 has on its side turned towards the outside of the frame 1 a profile projection 11 which, as shown in FIG. 3, in the relaxed state of the outer profile seal 8 obliquely at an acute angle to the profile central web 12 (cf. 3) protrudes and is provided at its outer end with a short nose 13 which is bent approximately at right angles to it and which points back to the central web 12 at an acute angle. The sash 1 encloses a frame opening 6 on its outside of the frame (ie in FIG. 1: the left side of the frame in the drawing) and the glass retaining strip 4 encloses an opening 7 on the opposite side of the frame. The glass rebate bend 2, which defines the boundary on the outside of the sash 1 of the frame opening 6, has on its circumferential inner edge facing the outer glass pane 3 (ie the edge at which the inner side surface of the glass rebate fold 2 facing the outer glass pane 3 merges into the radially outer boundary surface 29 of the frame opening 6 to form the outer frame opening 6). a in the direction of the frame opening 6 protruding small circulation web 10, which is completely covered in the form of a cap by the profile projection 11 of the outer strand seal 8 and the outer nose 13 attached to it. The length of the nose 13 of the profile projection 11 is selected so that it completely covers the outer side surface 18 (ie the outer surface of the circulating web 10 facing away from the outer glass pane 3) and with its end surface as far as possible against the circumferential surface 29 which defines the opening 6 radially on the outside comes to the plant. The profile shape of the outer strand seal 8 (cf. also illustration according to FIG. 3) is to be chosen in a relaxed state, that the shape of the profile projection 11 and its end nose 13 are essentially adapted to the shape of the circumferential web 10, although - as from Fig. 3 can be seen - the rest position of the profile projection 11 and the nose 13 of the outer profile seal 8 is selected so that it in assembled state, that is to say when the circulating web 10 is covered, undergo an elastic prestress. 1 that the outer side surface 18 and the inner side surface of the circulating web 10 facing the outer glass pane 3 run parallel to one another in the embodiment shown, while - as FIG. 3 shows - the sealing profile of the outer seal 8 in the relaxed state has no parallelism of the nose 13 and the central web 12, reference being expressly made to the drawing in FIG. 3 in this respect: rather, the nose 13, as can be seen from FIG. 3, is inclined at a slight angle to the central web 12 , This angular inclination is chosen so that in the assembled state (see FIG. 1) there is a corresponding elastic pressing force of the nose 13 against the outer surface 18 of the circumferential web 10. The same also applies to the profile projection 11, which in its rest position also has a smaller angle to its central web 12 than during later installation (FIG. 1). In this way it is achieved that in the entire area of coverage, ie in the entire contact surface between the profile projection 11 and the end lug 13 on the one hand and the corresponding outer surfaces of the circumferential web 10 on the other hand, an elastic pressing of the profile of the outer seal 8 against the circumferential web 10 in assembled state takes place. As can also be seen from FIG. 3, longitudinal ribs 27 are arranged on the inside of the nose 13 and longitudinal ribs 15 are also arranged on the outside of the central web 12: in the assembled state, this can result in pressure peaks occurring at the corresponding contact points because of the elastic pressure, So that penetration of moisture from the outside, for example, is prevented even better by the seal, in particular since this moisture can get through between the sealing projection 11 and the nose 13 on the one hand and the circulating web 10 on the other hand, and would even have to migrate "uphill" .

On the side of the outer strand seal 3 facing the outer glass pane 3, in addition to the abovementioned stops 15 and 26, inclined sealing lips 16 are also arranged between the two stops 15 and 26.

Furthermore, the profile projection 11 merges into a sealing lip 14 which is oriented obliquely towards the outer glass pane 3 (cf. also FIG. 3), which in the installed state (cf. FIG. 1) is also elastically bent by the outer glass pane 3 and thereby again under elastic There is pressure against this glass.

The entire inner end part of the outer profile seal 8, which consists of the sealing lip 14, the profile projection 11 and the outer covering nose 13, is a self-contained, optically pleasing and extremely effective sealing device at the relevant end of the central web 12, the profile projection 11 and the nose 13 prevents the undesired penetration of moisture between the profile seal and the circulating web 10, and the sealing lip 14 together with the sealing lips 16 prevent moisture penetration on the way directly over the outer surface of the outer glass pane 3.

The fact that the outer seal 8 is slipped onto the glass rebate bend 2 by means of the profile projection 11 and the nose 13 over the circumferential web 10 also ensures that a particularly simple and quick assembly and disassembly is ensured during assembly of the entire arrangement: because before the glass pane 3 is inserted into the opening within the casement 1, the outer strand seal 8 is first attached by being pushed over the circulation web "10 in the manner already described: this not only prevents the undesired penetration of moisture later, but before the installation of the glass panes 3 ensures that the assembled outer strand seal 8 has a firm mounting seat. If the outer strand seal 8 is attached, the glazing, for example the insulating glazing 3 shown, is then pushed in, then the glass retaining strip 4 is installed and fastened from the inside of the casement 1, and finally the inner strand seal 9 is then inserted into the sealing gap between the inner glazing bead 3 and inserted the inner side surface of the glass holding strip 4.

The inner strand seal has a profile in the idle state, as is shown by way of example in FIG. 4: the essential thing about this profile is that it has a sealing section 19 which, as shown in FIG. 4, is bent approximately banana-shaped: with "banana-shaped "A round bulge is to be understood here, in which — as shown in FIG. 4 - the curvature of the profile center line of the profile cross-section has a curvature radius that continuously decreases somewhat in the area mentioned. Experiments have shown that such a "banana-shaped" curvature gives the best results; in some cases, however, satisfactory results can also be achieved even with curvatures which are purely in the form of a circular arc. The "banana-shaped" curvature required for the inner strand seal should therefore generally indicate in general that this is not a purely circular-arched curvature, but that in addition to circular-arched curvatures, in particular, curvatures with a changing curvature radius should also be recorded.

After the window glasses 3 and the glass retaining strip 4 have been installed, the inner strand seal 9 is then pushed into the gap formed between the glass retaining strip 4 and the glazing 3 from the side of the opening 7. As shown in FIG. 4, a small protruding nose 23 is attached to the end of the bulging section 19 on the side of the seal 9 facing the glass retaining strip 4, which protrudes as a stop and alignment aid when inserting the Stran ^g seal 9 is used in the gap mentioned: the seal is inserted until the nose 23 on the inner edge 28 of the glass retaining strip 4 comes to a stop. When the sealing profile 9 is inserted into the gap mentioned, the curved sealing section 19 of the inner strand seal 9 between the inner glass pane 3 and the inner side surface of the glass holding strip 4 facing it is deformed in the direction of a reduction in the bulge, and thereby a pretension is generated with which the entire glazing 3 is clamped both between the outer strand seal 8 and the inner strand seal 9. All tolerances that have to be compensated are compensated for by the elasticity of the curved sealing section 19 of the inner strand seal. It is recommended, however, to form the bulge section 19 of the inner strand seal 9, as also shown in FIG. 4, so that it is also able to exert the necessary prestressing and supporting forces for the glazing 3.

The sealing section 19 of the inner strand seal 9 is adjoined by a base part 20, which is provided on its side facing the glass retaining strip 4 with sealing lips 21, which are also elastically deformed when the inner extruded profile 9 is inserted ^- into the gap mentioned and thus under elastic prestress in make sealing contact with the inside of the glass retaining strip 4.

When the bulge section 19 is deformed during assembly, its inner bulge surface 25 facing the glass pane 3 is brought into an increasingly less arched position with increasing deformation: due to the deformation and tension that occurs, the said bulge rear side 25 of the banana-shaped arched sealing area 19 is at least over during installation brought a partial area of it into complete contact with the facing outer surface of the glass pane 3, as is shown in FIG. 1 with the reference symbol 30: it it can be seen there that, in the installation state shown, a complete contact with the glass pane 3 has already taken place over the entire foot region up to approximately half of the arch section. 1 and 4, there are hollow chambers 22 extending in the longitudinal direction of the profile, by means of which the stiffening behavior of the bulge area 19 can be suitably influenced: one or, as in FIG and 4, use two or more such hollow chambers, the cross-sectional profile of which can also be designed according to the respective requirements (round, oval, kidney-shaped or the like). In special cases, it can also be advantageous if plastic fibers (in particular glass fibers or carbon fibers) are attached here instead of or in addition to such hollow chambers. All suitable elastic sealing materials can be used as the material for the outer as well as the inner strand seal, it being particularly recommendable to provide the seals made of foamed material, although it is an advantage here, a completely closed, thin outer seal skin and only use a foamed material inside.

Also in the inner strand seal 9, as shown in FIGS. 1 and 4, the small nose 23 continuously merges into a sealing lip 24 directed obliquely against the glass pane 3, which is applied against the glass pane 3 under elastic pressure.

In Fig. 2 is a perspective schematic representation (partially sectioned) of a window with the sealing arrangement according to the invention is shown: one recognizes the sash 1 with the glass rebate 2, the window panes 3 arranged in the sash 1 and the glass retaining strip 4 mounted from the inside of the frame Glasfalzabkantung 2 and the outer window pane 3, the outer strand seal 8 and between the inner window pane 3 and the glass retaining strip 4, the inner strand seal 9 is shown in the assembled state. The figure shows particularly clearly that the sealing arrangement described in particular also leads to its very pleasing external overall impression.

The sealing arrangement shown is described using the example of a wooden window, but can equally well be used in a door with a window insert or in other wooden sashes in which window panes are to be fitted in a sealing manner.

The sealing arrangement according to the invention thus makes it possible, with simple construction and rapid assembly, to also provide glazing in wooden windows or wooden doors, in which a secure seal against the ingress of moisture is ensured even when relatively large installation tolerances occur. Prefabricated sealing profile strands can be used without the need to mill special undercut grooves on the sides of the glazing bead or glass rebate cover facing the glass surfaces. The problematic entry of even the smallest amounts of moisture into the sealing gap in wooden windows or wooden doors is reliably and permanently avoided by the invention.
