"Sealing tape"

■ Lawyer file 33> 5 Pt.

The invention relates to a sealing tape for sealing between a glass pane and a frame rebate against which the glass pane is pressed by clamping elements.

A proposal for such a disk holder can be found in DBGM 7 211 452 by the same applicant. However, this utility model does not represent a novelty prejudice. The latter is on the inside of the window, while a double-sided adhesive tape is provided between the glass pane and the contact fold on the weather side. The latter takes over the sealing on the outside of the ^ ¥ © tter, whereby the. The adhesive properties of the sealing structure s® are great, so that the seal is not lost even under strong winds.

This construction has proven itself. However, there is a factual part from the fact that the sealing tape is constantly subjected to pressure by the tensioning elements. To achieve an optimal For an adhesive effect, however, it would be sufficient to compress the tape only a few tenths of a millimeter at right angles to the plane of the pane Bu and then relieving them of these compressive forces in the permanent operating state.

The invention is thus based on the Aur ^ abe, starting from the the above knowledge of the inventor, the sealing tape intended for the pane holder explained above with regard to its To improve the sealing effect.

This object is achieved according to the invention in that the self-adhesive sealing tape made of a permanently plastic material, e.g. polyisobutylene PlB and over its Length at a distance from each other, the sealing tape has transversely penetrating recesses, in each of which an elastic, e.g. made of neoprene or SBB rubber? "Standing buffer inserted whose length is less than the thickness of the sealing tape.

The sealing tape can have concave contact surfaces, the length of the buffers then being approximately the thinnest Cross-section of the sealing tape corresponds.

The new sealing tape fulfills the mechanical condition explained above with relatively little effort. By the Inserting the clamping elements into the pane holder, the sealing tape is elastic except for the free ends of the inserted Deformed buffer. The deformation path of the

Tape up to the point of contact on the buffers be about 1.0 "to 1.5 mm", because then an optimal adhesive effect is achieved. If the contact surfaces are concave, the Waviness in the glass can be absorbed without reducing the sealing effect. The sealing tape is relieved of wind pressure and spring forces during operation due to the mechanical stabilization the locally inserted elastic buffer. The latter are expediently made of a material that covers the glass surface not injured when touching contact. SBH rubber can be used because the buffers acting as spacers with the Do not come into contact with the outside atmosphere.

The recesses for receiving the elastic buffers can be in the sealing tape can be punched or embossed in a continuous process.

In order to achieve a high level of stabilization of the buffers with the smallest possible surface, they preferably have a doubly symmetrical one Cross-section on. The centrifugal moment Jxy is then 0; the Mohr's ellipse of inertia thus forms one Circle.

Some exemplary embodiments of the invention are shown in the drawing. Show it:

FIG. 4 shows various embodiments in cross section the elastic buffer.

The pane holder shown in FIG. 3 consists of a glass retaining bead 1 and arranged on the inside of the window an optionally consisting of several clamping elements arranged at a distance from each other clamping profile 2, which is with one of its legs is supported on the glass retaining bead 1 and with its other leg on the glass pane 3. The latter will printed under the pressure of the clamping profile against a frame fold 4, with one on both sides between the glass pane and the Hahmenfalz adhesive sealing tape 5 is provided. Figure 1 shows that the contact surfaces 6 of the sealing tape 5 are concave can be formed. The gap between the glass retaining bead 1 and the glass pane 3 is preferably made of plastic existing profile 7 covered.

The figures show that over the length of the sealing tape 5 arranged at a distance from one another and the sealing tape transversely penetrating recesses 8 are provided, in each of which a elastic buffer 9 is inserted. The latter has a length which corresponds to the thinnest cross section of the sealing tape Fig. 1 corresponds to or is smaller than the thickness of the sealing tape (Fig. 2). Figure 4- shows different embodiments of the Buffers, all of which have a double-symmetrical cross-section.

The pane holder is installed from inside the tree. When inserting the clamping profile 2, the contact surfaces 6 of the belt 5 are deformed so far that the inward facing ends of the elastic buffers 9 lie within the vertical sealing surface and thus on the glass pane 3.

The elasticity of the buffer 9 must be considerably less than that of the sealing tape 5 »so that the buffer acts as a stabilizing element works.
