The innovation relates to a glazing of the type mentioned in the generic term of claim 1.

Such a glazing seal is already known (BP-PS 22 130 and 22 131). It has the advantage of lower manufacturing costs compared to glazing seals made of different materials, namely a homogeneous round rubber body and an inhomogeneous foam rubber part with a large number of axially closed cavities, as formed in patent application P 36 17 853. It is important with such glazing seals that they can also be easily installed around corners without the sealing function being impaired by the formation of folds.

The innovation is based on the task of further improving the glazing seal of the type mentioned above, despite its simple manufacture, so that it can be easily installed around bridges and is characterized by good sealing function even in firedamp conditions.

Hett&reag is a Sshtttaaaeprttefc l identified and in onteranPröchen as well as in the character description further developments of the same are given.

Instead of very soft foam rubber, which is provided with many small cavities and has only a very low big end depth,

"2 ·■ 18.02.1988

ability, it is recommended to use inherently rigid, homogeneous, pore-free material, especially with gunnnie-elastic properties, to improve the sealing and to improve the profile shape. It is not necessary to use rubber. Soft PVC is recommended as a suitable material, especially on a plastic basis. A polynorbornene elastomer, such as that sold under the brand name N(HtSOREX by CdF, also has very good properties. According to DIN 7724, elastomers are steel-elastic at low temperatures and rubber-elastic at normal temperatures of 20* and above, with high reversible deformability and shear modulus values between 0.1 and 100 MPa. TPE (thermoplastic elastomers) and plastics with less rubber-elastic behavior can also be used in special cases.

In itself, it is already known (OE-PS 31 21 230) to have a web protrude from the base part of a profile seal, on the side opposite an anchor foot, which serves as a kind of "anvil" for a leg-shaped sealing lip when it is pressed by the window glass towards the base part onto the outer surface of the web. The web is located here approximately in the middle of the base part, but does not act as a sealing lip.

In addition, a sealing strip is also known (DS-GM 1 912 214) in which a swan-shaped leg in cross-section is attached to one side of the base part and a sealing lip with an approximately triangular cross-section is attached to the other side. Apart from the fact that no anchoring by means of an anchor base is provided here, the sealing lip has another task with considerable curvature towards the outside and has shown that such sealing lines are difficult to lay around beacons without forming folds.

However, with the new training, the tasks can be solved in a very good way.

After developing the innovation, it is recommended that the sealing lip is placed on the base part on the side facing the weather side and opposite an anchor foot in such a way that a rounded tip of the "triangular profile" that serves as a sealing dome is furthest away from the base part. The base part can even be completely missing on the other side facing away from the weather side, because the anchor foot provides sufficient stability there. This makes laying around corners much easier.

For example, if the cross-sectional thickness or cross-sectional height of a profiled sealing lip with a substantially triangular cross-section is approximately twice to three times as large as the cross-sectional thickness or cross-sectional height of the base part, in order to counteract the resulting concentration of material in the area of the sealing lip, it is recommended to create a cavity, particularly in the center of the sealing lip, which also has a substantially triangular cross-section with well-rounded tips or corners. The cross-sectional width of a preferably molded sealing handle, on the other hand, should be considerably smaller than the total cross-sectional thickness or height of the sealing lip and, if possible, also of the base part.

As with the state of the art, it is recommended that the head of an additional leg in the relaxed position is at least as far from the base part as the tip of the sealing lip. It was found that a ratio of between 1.05 and 1.5, and in particular at least 1.1, between the distance of the head of the leg from the base surface of the base part to the distance of the tip of the sealing lip from the base surface allows particularly favorable conditions for laying and sealing.

or frame side a wave-shaped indentation. The cavity in the sealing lip and/or in the anchor foot can have various shapes such as circle, triangle, oval, rectangle, square, ellipse or carafe. The base part can have a bead on the side facing away from the sealing lip. The side edge, which extends diagonally from the top to the base part, is inclined at an angle of between about 20 and 40° to the normal to the central axis MA of the anchor foot; this angle of inclination is also called the "lip inclination". All of these measures serve to make the seal even more rubber-elastic due to its geometry.

The anchor foot is preferably offset eccentrically in relation to the base part. The anchor foot preferably has a conical taper in cross-section that is away from the base part and possibly also faces it, which makes insertion much easier, and is designed in the manner of a dovetail. The anchor foot preferably has a rounded crown arm and, as already mentioned above, can also have a cavity.

The parallelogram-shaped or triangular sealing lip has, appropriately, a wave-shaped indentation on the glass side and/or frame side, possibly with a steep hill. The cavity in the sealing lip and/or in the anchor base can have various shapes such as a circle, triangle, oval, rectangle, square, ellipse or carafe. The sealing lip can have a bead on the base part. All of these measures serve to make the seal even more rubber-resistant due to its geometry, without having to use foam rubber with its disadvantages.

Thread made of e.g. cord, polyester, glass fibers, polyamide or metal extruded in. It is already known (US-PS 19 18 134) to embed springs in sealing cords.

Furthermore, the use of a non-cellular, i.e. cell-free solid material (apart from the large cavities mentioned above) with a hardness between 15 and 70, especially between 30 and 60 IRHD for the sealing lip is recommended:.

The glazing seal according to Fig. 1 consists of a base part 1, from which a sealing lip 2 with a parallelogram-shaped cross-section extends on the weather side W and a leg 3 on the inside R of the room. The double-gram-shaped sealing lip 2 has a wave-shaped indentation 4 on its glass side, i.e. the sealing side or surface 20 facing away from the base part 1. This extends between the projection 21 on the weather-side outer corner of the sealing surface 20 and a support surface which is wider than the projection 21 _, for example for the glass pane 12 of Fig. 7. The axis of symmetry SA of the parallelogram-shaped sealing lip 2 is inclined outwards towards the weather side W at an angle of inclination/7 of approximately 20* in relation to the normal NE on the base part 1. In the area la the base part 1 and the sealing lip 2 overlap. The angle of inclination |* should be between 10* and 60*, in particular between 10* and 30*.

An anchor foot 7 protrudes from the underside of the base part 1. The anchor foot 7 has the shape of a rounded cross and is located approximately in the middle of the base part 1. It can also be slightly offset in the direction of the leg 3 or the parallelogram-shaped sealing lip. A thread 8 made of textile cord is embedded in the middle of the sealing lip.

According to Fig. 2, the parallelogram-shaped sealing lip 2 has a

circular cavity 6 and a wave-shaped indentation 4. The thread 8 is located here approximately in the middle j of the anchor foot 7.

According to Fig. 4, the parallelogram-shaped sealing lip 2 is formed in the direction of the outside and the inner space R at a corner 2U of a leg 3, in the sealing lip 2 there is a circular cavity 6 and on the base part 1 of the sealing lip 2 there is a wave-shaped indentation 4. In the base part 1, approximately in the middle, there is a thread 8. In the anchor foot 7 there is an approximately oval cavity 9. The upper sealing edge of the head 14 of the leg 3 is at a distance A14 from the base surface 16 of the base part 1, which corresponds approximately to 1.35 times the distance Al5 of the sealing surface on the tip 15 of the sealing lip 2 from the base surface 16.

According to Fig. 5, the leg 3 protrudes from the base part 1 next to the parallelogram-shaped sealing lip 2 and faces away from it towards the inside of the room R. The leg 3 has a swan neck shape in cross section, just like in Fig. 4. In the base part 1, approximately in the middle, a thread 8 made of cord is extruded. The sealing lip 2 has a circular cavity 9 and the anchor foot 7 has a carafe-shaped cavity.

In Fig. 6 and 7, a glazing seal according to Fig. 4 is shown in the installed position. The window frame 10 has an inverted T-shaped receiving groove 11 for receiving the anchor foot 7, so that the glazing seal 13 can be anchored without interruption and mounted around the corner. The ends of the glazing seal 13 are only connected to one another at a single joint (not shown), e.g. by gluing. The glass pane 12 lies tightly against the head 14 of the leg 3 and against the tip IS of the parallelogram-shaped sealing lip 2.

The shape of the seal allows for a large tolerance range when installing. Even if the dimensions of the glass pane 12, the sash, the frame 11 or the clear strip are thicker than theoretical, this seal will ensure the function of the glass pane 12.

fulfills a "solid seal against atmospheric influences" requirement. The same applies vice versa if the dimensions of the oil seal are thinner than usual. The glazing beads behave similarly according to fig. 1, 2, 3 and 5.

Due to the possibility of avoiding the compressed, parallelogram-shaped sealing lip 2, which is not made of μγβα rubber and is always mounted on the weather side W*, the formation of folds is practically impossible with this type of glazing seal.

Of course, the seal can also be used to seal panes or panels other than glass. It can also be used on door frames.

A temperature range between 15 and 7C IRHD, especially between 30 and 50 IRHD, is preferred.

According to Fig. 8, the glazing seal does not have an anchor foot, in its place the base surface 1b of the base part 1 is fastened by means of an adhesive layer 23. Here too, the weather-side outer corner of the sealing lip 2 is provided with a rounded projection 21, to which the concave recess 4 adjoins, before it merges into the convexly curved support surface 22.

The glazing seal according to Fig. 9 consists of a base part 1, from which a substantially flat cross-sectional sealing lip 2 protrudes on the weather side W and a leg 3 on the roof side F. In addition, the sealing lip ? has on its glass side, ie the sealing side on the surface 20, a wave-shaped indentation 4 below the cap 15 serving as the seal - indented in relation to the seal. The axis of symmetry SA of the sealing lip 2 is here under an inclination.

angle A/ of approximately 60° to the normal NE on the base part 1 or its base surface Ib. With this design, inclination angles between approximately 50" and 80* are preferred.

An anchor foot 7 protrudes from the underside of the base part 1, which has the shape of a dovetail in profile and is offset from the center of the base part 1 in the direction of the leg 3. A thread 8 made of textile cord is embedded in the center of the anchor foot 7 - in the area of its center axis HA.

As in Fig. 10, the sealing lip 2 has a hollow space 6 which is elongated in cross-section or profile, the ends of which are rounded and the width or height of which increases with the width or height of the sealing lip 2 to the left in Figs. 9 and 10, ie towards the weather side W. j

The anchor foot 7 has conically inclined lower edge surfaces 7d, ie tapering towards the central axis A, with an angle of inclination of about 20-25°, as well as further, adjoining upper edge surfaces 7a and 7b, whose angles of inclination d~ are about 3*10* and £ about 25-35*, i.e. they are different. The alternative in Fig. 10 has the advantage of being very easy to lay around corners, since the base part 1 in the area of the anchor foot 7 above the side facing the interior of the room R with the upper edge surface 7a with the larger angle of inclination of 30* is missing.

The glazing seal 1 is provided with a bead 5 on the edge of the base part 1 in the area of the weather side W. The bead 5 protrudes from the ease surface 16 of the base part 1 in the same direction as the anchor foot 7.

According to Fig. 9, the glazing seal is provided with a swan-neck-shaped leg 3. The upper sealing edge of the head 14 of the leg 3 is at a significantly greater distance from the base surface 16 of the base part 1 than the sealing surface on the tip 15 of the sealing lip 2 is from the base surface 16 (in the relaxed state). The leg 3 starts from the right edge of the base part 1 and from this (edge facing the inside of the room) and is directed towards the weather side W and towards the sealing lip 2 with an upwardly curved shape.

The shape of the seal allows for a large tolerance range during use: If, for example, a pane of glass, to which the head 14 and the dome 15 seal, is chosen to be thicker than theoretical, the glazing seal will fulfil its function and ensure good sealing against atmospheric influences. The same applies vice versa, i.e. if the dimensions of the pane of glass are chosen to be thinner than usual. The possibility of deflection of the sealing lip 2, which is compressed in the sealing state and is always mounted on the weather side W, practically eliminates the formation of folds with this type of glazing seal. Of course, the seal can also be used to seal panes or panels other than those made of glass. It can also be used on door frames.

Here too, a hardness between 15 and 70 IRHD, especially between 30 and 50 IRHD, is preferred.
