Elastic extruded sealing profile for Sealing glazing for the wings

of windows, doors or the like.

The invention relates to an elastic extruded sealing profile for sealing glazing for the wings of wooden windows, wooden doors or the like, with a head region and a foot region connected to it via an intermediate web, the head region consisting of two sealing lips and the foot region comprising two retaining ribs protruding from the lower end of the intermediate web, the sealing lips and the retaining ribs each point in opposite directions from the intermediate web, a sealing lip and the retaining rib pointing to the same side are provided in the installed state to rest on the surface of the glazing to be sealed, and putty fillings made of permanently plastic putty are arranged in chambers on both sides of the intermediate web.

To seal glazing in wooden windows, wooden doors, etc., prefabricated elastic plastic extruded sealing profiles can be used instead of cementing or sealing. Unlike with plastic or metal windows, where such extruded sealing profiles can be used from the outset in the glazing rebate area, since when the windows are extruded, corresponding groove profiles that allow the sealing profile base to hook or lock can be extruded without much additional effort, the use of such sealing profiles in wooden windows etc. is possible, but proves to be very complex, since the corresponding shaped grooves have to be milled in afterwards. For this reason, such seals with prefabricated profile extruded profiles are rarely used in wooden windows, since the introduction of corresponding profile grooves is a work step "against the production process".

When glazing wooden windows, wooden doors or similar, an essential criterion is that the upper visible edge has a

_R represents a "clean" finish of the sealant used. If a

If sealing or grouting is carried out, the ability of the person who injects the grouting or sealing compound into the corresponding groove on the side of the glazing is very important in order to achieve a clean upper finish. If a person who is experienced in this falls, for example,

_n , there is a great risk that a temporary worker will not work cleanly enough

and wavy or clearly uneven visible surfaces are created, which is immediately visible to every observer when looking at the finished window.

DE-GM 86 12 008 describes an extruded sealing profile in which the retaining lips of the foot area are on the side facing away from the glazing

and start from a thickened profile section at the base area, which is provided with a contact surface for the glazing on the side facing the glazing. Between this and the head area of the seal there are two elastically bendable sealing lugs above the thickened profile.

__. section, which in the non-installed state of the seal over the

The sealing on the glazing side is essentially carried out via the large contact surface along the strip seal and the two smaller sealing lips in front of it in the head area, with the foot area of the seal in cross-section just in the

2g Section where the contact surface is formed is particularly thick,

whereby a good connection over the entire contact surface and thus an effective seal can be achieved. Although this well-known wood glazing seal works completely satisfactorily in most applications, it has nevertheless been shown that sometimes, even if only

nn rare, but still leads to unwanted penetration of moisture

can occur, both on the side of the strip seal facing away from the glazing and on the side facing the glazing.

From DE-OS 37 06 503 a sealing profile of the type mentioned above is

O ₅ , in which the two sides of the middle intermediate bar in the foot area

provided putty fillings with permanently plastic putty in relatively small

Deventer Profile GmbH & Co. KG
(GM 490/55-90)

When the base area of this seal is pressed into the retaining groove, the receiving chambers are deformed in such a way that the putty fillings contained therein are at least partially pressed out and then form a seal against the counter surface to be sealed. This seal

can be installed quickly and easily and also provides an excellent upper visual surface. The overall structure of this well-known strip seal with individual, sometimes multiple receiving chambers on each side of the seal and intermediate sealing lips protruding between them is _1Ω relatively complicated and does lead to improved sealing results compared to seals without such lateral putty fillings, but there are still applications in which the sealing effect of this well-known strip seal is not yet completely satisfactory.

. ,- Based on this, the invention is based on the object of

To further develop the strip seal of the type mentioned above so that it while maintaining easy installation and a flawless design of the upper visible surface, it provides an even better sealing effect when sealing wooden glazing and at the same time a simple structure of the

2Q seal achieved.

According to the invention, this is achieved in a strand seal of the type mentioned at the beginning in that a continuous putty filling is provided on both sides of the intermediate web, extending over the entire height of the intermediate web, which is limited at the top by the sealing lip of the head area projecting onto the relevant side and at the bottom by the corresponding retaining rib of the foot area, rests against the intermediate web and extends (in the unloaded state of the strand seal) up to close to the free end of the relevant sealing lip or retaining rib.

The strand seal according to the invention provides an almost ideal way of

The sealing advantage of a cement with the advantage of an easily insertable strand seal that always ensures a clean, flawless visible surface is achieved by incorporating corresponding, continuously effective cement fillings of relatively large volumes on both sides of the sealing gap into an elastic strand seal. As a result of the

Deventer Profile GmbH & Co. KG
(GM 490/55-90)

Due to the deformation of the elastic sealing profile that occurs when the strip seals the gap between the wooden rebate and the glazing, the putty fillings on both sides of the intermediate web are pressed into their laterally open ,- receiving chambers and are thereby pressed against the glazing or the

The permanently plastic properties of the putty fillings ensure that all gaps between the end areas of the sealing lips of the head area and the retaining ribs of the foot area that are adjacent to the corresponding counter surface (glazing or wood rebate) are completely and thoroughly filled.

extend over the entire height of the intermediate piece in the original state. This creates a putty seal on the glazing or the glass rebate over the entire height of the intermediate piece, whereby the elastic deformation of the retaining ribs and the

, c Sealing lips in the foot and head area between both sides of the

The permanently plastic putty fillings in the intermediate web are always under a certain pressure and are therefore held in good contact with the counter surface to be sealed. On both the glazing and the glass rebate side, a seal is required that extends over the entire height of the seal.

^ _n extending, continuous putty sealing surface is created so that a completely

excellent sealing effect that can hardly be improved. At the same time, the sealing lips arranged in the head area, which form the upper end of the filling to the outside, always ensure a visually flawless, "clean" visible surface, without the user needing any special skill. The permanently plastic mass of the putty fillings used in the strand seal according to the invention, which preferably consists of a butyl-based putty (such as the putty available commercially under the name "Egosit"), also ensures that in the event of any, even the smallest, changes in the position of the individual parts in relation to one another,

OQ and the putty filling always takes such changes into account, e.g. in

any cavities that occur are pressed in so that undesirable cavities do not occur. The elastic "supporting structure" of the inventive strand seal for the putty fillings, which, roughly speaking, is in the form of a "double-T-beam", also serves to

that the putty fillings are well stabilized and a problem-free and also

easy handling of the strip seal according to the invention at the installation

Deventer Profile GmbH & Co. KG
(GM 490/55-90)

It should also be mentioned here that the permanently elastic putty required in the invention generally also has a certain adhesive effect, which improves the sealing effect when the

Strand sealing further increased,
&ogr;

In the case of the strip seal according to the invention, the putty filling is particularly preferably introduced in the form of a putty strip into the two lateral receiving recesses formed by the intermediate web, the sealing lip pointing to the relevant side and the _ corresponding retaining rib. This

Putty strips can be easily and simply pressed into the receiving recess, whereby the permanently elastic putty adapts to the shape of the recess.

Preferably, the lateral outer surface of each putty filling facing the respective outer side of the strand seal _R runs in the strand cross-section

straight or wavy. If the cross-section is wavy, it is easier to insert the seal into the receiving gap, and the subsequent squeezing of the putty within the gap results in the wavy lines on the counter surface to be sealed being leveled out.

In the invention, it is particularly advantageous if the head area

or the sealing lips forming it are made of a softer, elastic material than the intermediate web and the foot area or the retaining ribs forming it. This is because the soft design of the sealing lips enables them to easily conform to the counter surfaces of the glazing or the

The glass rebate is reinforced, while the harder intermediate web and foot area contribute to better anchoring in the receiving groove and to an effective support structure for the putty fillings.

ofl A further, particularly preferred embodiment of the inventive

The advantage of the extruded sealing profile is that the intermediate web has a cross web in its upper end section facing the head area of the seal, which runs transversely to it and is connected to the underside of the corresponding sealing lip(s) and which is at a distance

O ₅ from the free end of the sealing lip(s) covering it still within the

lateral putty filling(s). This crossbar is particularly preferred only

Deventer Profile GmbH & Co. KG
(GM 490/55-90)

on one side from the intermediate web, advantageously on the side that faces away from the glazing when installed. If the head area, i.e. the upper sealing lips of the strip seal that form it, are made of softer, elastic material than the intermediate web and the retaining ribs on the foot area, then the preferred design of the invention described means that the middle section of the head area, which in any case also covers the middle area of the receiving groove when the strip seal is inserted into the receiving groove, is advantageously stiffened by this cross web, while the softer end areas of the sealing lips that protrude beyond the cross web nestle particularly well against the corresponding counter surfaces for sealing and can easily carry out the stronger deflections that occur particularly on the glazing. This ensures a very good sealing effect both against the glazing and against the glass rebate in the area of the head sealing

lips achieved.

A further, preferred embodiment of the strip seal according to the invention is achieved by providing the intermediate web with openings. As a result, the putty fillings on both sides of the intermediate web can be connected to one another via these openings, which results in further stabilization of the putty fillings and improved retention of the same on the intermediate web (when the strip seal is not yet installed).

A preferred further development of the invention also consists in the fact that the retaining ribs are set upwards towards the head area and each form an acute angle with the intermediate web. This facilitates the introduction of the strip seal according to the invention into its

on _the side of the glazing. Especially

Preferably, the holding ribs are elastically deformed by the putty filling in the direction of an increased angle of attack (relative to the intermediate web), i.e. the angle of attack of the holding ribs relative to the intermediate web is smaller before the putty filling is introduced into the strand seal, so that

of- the retaining ribs are elastically bent by the putty filling

become.

Preferably, in the extruded sealing profile according to the invention, the entire top of the head area is covered with a removable paint protection film in order to adequately protect the sealing lips on the profile head until the painting work on the window has been completed, after which the paint protection film can be easily removed by hand.

_ In the case of the strip seal according to the invention, the relatively large putty masses, which are stored in the side pockets, ensure excellent filling of the groove by the putty over a large sealing area, and open up the possibility of being able to implement the strip seal profile in the frame corner without corner welding, since

_R Deflection of the profiles in the frame corner only the hard profile part (intermediate

web and retaining ribs on the foot part), while the soft profile part (head area) can remain without cutting. Before the frame is pressed in, an appropriate amount of putty is injected into the corner of the frame in the window or similar using a syringe and then the profile frame is inserted. The putty filled with the syringe will then

The open frame corner area between the gaping (harder) profile parts is completely filled (if not enough putty has been applied, more putty can be added using the syringe), so that a continuous, self-contained strangle profile frame with excellent sealing properties is created that is easy to manufacture and assemble.

The invention is explained in more detail below using the drawing as an example. They show:

Fig. 3 is an enlarged view of the installation of the extruded sealing profile shown in Fig. 1 for sealing a wooden glazing, as well as

Fig. 4 shows an (enlarged) corner section of a surrounding profile frame with an extruded sealing profile according to the invention as shown in Fig. 1.

Fig. 1 shows an enlarged perspective view of a short section of an elastic sealing profile strand for sealing wooden glazing, i.e. a pane of glass in a wooden frame that accommodates it, for example in a wooden window or a wooden door. The elastic sealing profile strand has a head area I, a foot area 3 and an intermediate web 2 connecting the head area to the foot area. The foot area 3 is made in one piece with the intermediate web 2 from a suitable elastic material, which, however, has a greater hardness than the elastic material of the head area 1. Such profile cross-sections consisting of two elastic materials of different hardness can be produced without difficulty by coextrusion.

As shown in Fig. 1, the head region 1 consists of only two sealing lips 4, 5 and the foot region 3 consists of the intermediate web 2 with only two retaining ribs 6, 7 projecting laterally at its lower end, whereby the sealing lips 4, 5 and the retaining ribs 6, 7 are arranged relative to the intermediate web 2 in such a way that

on each of the two sides of the intermediate web 2, one sealing lip 4 25

or 5 and a holding rib 6 or 7 protrudes. In the area between the sealing lips k, 5 and the holding ribs 6, 7, no further intermediate lips or intermediate ribs are formed. The width of the head region 1 is greater than that of the foot region 3, since the foot region 3 only has to be accommodated in a receiving groove with a narrower groove width than its lateral width, while the sealing lips 4, 5 of the head region 1 not only cover the receiving groove for the strand seal, but also have to form an additional sealing contact surface against the glazing and the wooden rebate with their lateral end regions, as can be seen from Fig. 3, which shows such a seal in a basic representation in the installed state.

According to Fig. 1, a crossbar 9 is formed integrally with the upper end of the intermediate web 2, which runs transversely to it and only protrudes from the intermediate web 2 on one side, namely on the side that faces away from the glazing when installed (see Fig. 3). This crossbar 9 is attached to the sealing lip 5 on the underside of the head area 1 in a suitable manner, which is achieved, for example, by coextrusion. Since the head area 1 consists of an elastic material of less hardness than the intermediate web 2 (and the foot area 3), the crossbar 9 in the middle area of the head area 1 (slightly offset to the right) on the underside of the "soft" sealing lip 5 forms a reinforcement for the latter. However, the crossbar 9 only extends over part of the total extension of the sealing lip 5, i.e. it ends well before its free end. This makes it possible for the sealing lip 5 to be able to support itself particularly well against the counter surface on which it comes to rest or to "snuggle up" there due to its softer material (see Fig. 3).

On both sides of the central web 2, the sealing lip 4 and retaining rib 6 or sealing lip 5 and retaining rib 7 protruding on one side each

trough-shaped receiving chambers for two putty fillings 10 made of permanent A U

plastic putty, preferably butyl-based. These putty fillings 10 are preferably introduced into the receiving chambers in the form of putty strips, whereby, as shown in Fig. 1, in the non-installed state of the strip seal the entire receiving area of each trough up to the respective side

_ _R outer end surface 10a of the putty filling 10 completely with putty

The putty filling extends from the intermediate web 2 laterally to close to the free ends of the sealing lips 4, 5 and the retaining ribs 6, 7, whereby the putty fillings 10 extend up to a distance A (Fig. 1) to the free end of the sealing lips 4, 5 or by a distance B to the free end of the

_qn retaining ribs 6, 7. The distance A is greater than the distance

B, preferably 2 to 3 times larger.

The retaining ribs 6, 7 formed in the foot area 3 run in a pointed

Angle to the intermediate web 2 (upwards, i.e. towards the head area 1)

„p- inclined. The angle is slightly

smaller than after their insertion, since the retaining ribs 6, 7 under the

Deventer Profile GmbH & Co. KG
(GM 490/55-90)

IO-

The effect of the putty fillings 10 can be elastically bent slightly in the direction of a larger value of the angle.

c Between the two retaining ribs 6, 7 there is a small round notch 8 at the foot area 3

designed to facilitate pivoting of the two retaining ribs 6, 7 relative to the intermediate web 2.

In Fig. 2, another embodiment of such a sealing profile is shown. This differs from the profile shape according to Fig. I in

in that the upper crosspiece 9a protrudes over the intermediate web 2 on both sides, whereby a stiffening is created not only for the sealing lip 5 resting on the glass rebate, but also for the sealing lip k resting on the glazing in the middle area of the sealing head. Furthermore, p. the intermediate web 2 has several

Openings 18 into which the putty fillings 10 are pressed when they are inserted into the receiving recesses and thus come into a holding connection with one another.

„_. In addition, the profile in Fig. 2 also has the

Sealing lip 5 of the head area 1 at its free end area 13, with which it projects over the underlying crosspiece 9a, is designed with a smaller cross-sectional thickness than in the middle area of the head part 1, so that here the putty filling 10 extends laterally over the crosspiece 9a by a larger distance

_O c can run up to the bottom of the thinner end area 13. This

End region 13, which is made of softer material than the intermediate web 2, due to its thin design, enables particularly good and easy conformability to the surface of the glass rebate on which it comes to rest.

The strip seal shown in Fig. 1 to 3 is on its head area 1

covered with a paint protection film 1 1, which can be easily removed after the strip seal has been installed and after the wooden frame has been painted. The surface 10a on the outside of the putty fillings 10 is, as shown in Fig. qc 1, smooth, i.e. in cross-section the surface 10a appears in the form of a straight line

However, it can also, as in the embodiment shown in Fig. 2, be

(GM 490/55-90)

The cross-section should be wavy, which makes it easier to insert the extruded profile into the receiving groove between the wooden rebate 15 and the glazing 14 (see Fig. 3).

Fig. 3 shows a greatly enlarged section of a

Arrangement consisting of a glazing 14 and a wooden glass retaining strip 15, which is provided with a retaining groove 16 for receiving a strip seal at its upper end facing the glazing 14. The strip seal shown in Fig. 3 _n is one with a sealing profile according to Fig. 1. As Fig. 3 shows, in the strip seal pressed into the receiving groove 16 from above, the retaining ribs 6, 7 have been angled relative to the intermediate web 2 by the effect of the pressing, so that the angle of attack (Fig. 2) is smaller than in the non-installed state. This results in a volume reduction and displacement in the

lateral receiving chambers for the putty fillings 10, so that the putty is pressed under the pressure occurring within the respective receiving chamber in such a way that the relatively large amount of putty completely covers the entire area between the intermediate web 2 and the sealing lip 4 or 5 as well as the retaining rib 6 _or 7 and the counter surface of the glazing 14 or glass retaining strip 15.

This achieves two effects, namely the aforementioned pressure build-up in the putty, which leads to a good filling of the receiving chambers, and in addition an additional anchoring effect of the profile in the receiving groove 16 by the elastically deformed retaining ribs 6, 7.

Finally, Fig. 4 shows (greatly enlarged) a 90° frame corner of a profile frame made from such an extruded profile, with an extruded sealing profile with the profile cross-section shown in Fig. 1 being used. To form the frame corner, only the area below the head area is used.

oQ, the intermediate web 2, the foot area 3 and the putty fillings 10

The area of the strip seal is cut open, after which the two parts separated by the cut are "unfolded" at the interface by a 90° deflection of the head area 1, as shown in Fig. 4. The two parts are only connected in this corner area via the

og head area 1. Before installing this sealing frame, a

Deventer Profile GmbH & Co. KG
(GM 490/55-90)

Putty pre-filling 17 is introduced, e.g. using a putty syringe, and only then is the prepared, pre-cut frame inserted. When the frame is inserted, the putty pre-filling 17 in the receiving groove connects with the two cut end surfaces 19, 20 and fills the corresponding

free corner of the support frame between the end surfaces 19, 20 completely.

In this way , the all-round sealing frame can be installed quickly and easily and always results in an excellent-looking, uniform visible edge.

The crossbar 9 or 9a, with its end facing away from the glazing, represents a kind of "stop edge" which, when the extruded profile is pressed into -,&rgr;- the receiving groove 16 (Fig. 3), prevents a possible lateral

The upper profile part could move outwards (i.e. towards the glass rebate) too much. This is because the harder crossbar 9 or 9a in the direction of the wood then acts as a suitable "stop" that prevents the upper profile part from moving outwards to an undesirable extent.
