Description

The invention relates to a glass sealing strip for frames and / or glass retaining strips of windows or doors with inserted glazing, the frame from sections of Profiles and connecting them made at their corners are and the glass sealing strip with a locking part for Attach in trained on the frame or the glass retaining strip Grooves and a sealing part for contact and sealing the glazing is formed and on the sealing part its sealing surface coming into contact with the glazing Adhesive layer is applied and the locking part from one stiff material with a higher shore hardness than that Sealing part is made, the locking part a Footbridge with a locking bar protruding on one side having.

It is known to manufacture windows and doors from frames that from profiles by cutting profile sections to length Frame length and connecting are made at the corners. The glazing subsequently used in such a frame is sealed against the frame using glass seals.

So far, these glass seals are in the form of Glass sealing strips in the already from the profile sections  manufactured frame immediately before inserting the Glazing inserted. The profiles that make up the frame are produced, have grooves for snapping the Glass sealing strips on. Since the glass sealing strips in the already finished frames are inserted, it is necessary these before inserting them into the corresponding grooves on the to cut the respective section lengths within the frame. This represents a significant expense in the manufacture of Windows and / or doors.

To set the glass pane at right angles in the frame to secure, support blocks are in the adjustment grooves of the Frame inserted on two or more sides. This means at Part of a considerable amount of work.

From GB 2 279 101 a glass sealing strip is known which in a conventional manner in a corresponding receiving groove Frame can be used and on its glazing facing side has an adhesive layer on the Surface of the glazing is sealingly glued. It can thereby making a window or door with in the frame used glazing can be simplified. However, the proposed structure of the known is disadvantageous Glass sealing strip with one made of a plastic foam trained intermediate layer on which the adhesive layer is applied. It has been shown that a permanently secure sealing of the glazing against the Frame when using such a plastic foam layer is not feasible. Either with one elastic plastic foam no for sealing required contact pressure of the glass sealing strip on the Generate frame and glazing, or else the Plastic foam is so inelastic that it is Contact pressure can be generated, but not sufficient The glass sealing strip is more flexible unavoidable frame movements, e.g. B. in sunlight and compensate for warming. So in both cases it works  after a relatively short time the sealing effect of the known Glass sealing strip lost.

The invention is therefore based on the object To propose glass sealing strip that the glazing of Rationally enables frames for windows and / or doors, but at the same time a permanently secure seal also strong weather influences over the life of the window or the door.

The invention solves the problem with a Glass sealing strip according to the characteristics of the Claim 1.

Advantageous embodiments of the invention are the Removable subclaims.

The invention proposes that the sealing part with at least one running in the longitudinal direction of the glass sealing strip and facing the support web of the locking part Reinforcement rib is equipped and the at least one Reinforcement rib the sealing part opposite the support web supports, with the adhesive layer on the the glazing facing side with a removable masking tape is. The adhesive layer causes a firm fixation of the Glazing on the glass sealing strip and thus one reliable sealing, but also a special one firm connection between the glazing and the frame.

In order to achieve a uniformly high contact pressure good sealing effect over the entire sealing surface of the To achieve glass sealing strip according to the invention, strikes the invention that the sealing part with at least one in Longitudinal extension of the glass sealing strip and the Support web facing reinforcement rib is equipped. This reinforcing rib supports the sealing part against the Support web from so that the contact pressure is as uniform as possible over the entire sealing surface when placing the glazing  is exercisable. It is also possible to have two reinforcing ribs in to form uniform distances from one another.

To provide a stable support for the sealing part against the To reach the landing stage is the support surface of the Reinforcement rib on the support web wider than that on Transition to the sealing part. Furthermore, the Reinforcement rib are firmly connected to the support web, for example by an extrusion so that they do not come out of their Position can be pushed away.

To further increase the sealing effect of the invention Glass sealing strip on the surface of the glazing proposed according to the invention that the sealing surface with respect to the level determined by the support bridge by an angle α is inclined from 3 ° to 10 °, such that the outer Sealing edge of the sealing surface a greater distance from that Support web has as the inner edge of the sealing surface. On this way the sealing surface is used for the sealing effect critical area, namely where the glazing in the Frame occurs, enlarged, so that, for example, at the Water droplets running down from the glazing surface outer sealing edge resulting from the increased contact pressure the inclination of the sealing surface is reliably applied by an admission to the frame can be held.

The glass sealing strip is preferably in the frame applicable. But it is also possible to use them on both sides the glazing, i.e. also to be used in the glazing bead.

The adhesive layer is on the glazing Provide side with a removable masking tape. So it is possible, the glass sealing strip according to the invention already immediately after the production of the profiles for the frame, d. H. before cutting the profiles to those for the frame required profile sections, in the trained on the profile Retract groove for the glass sealing strip, the applied on the sealing surface  Adhesive layer for the glazing protected under the masking tape is. If now the profiles on the for the frame required profile sections will be cut to length at the same time the one already inserted in the profile Glass sealing strip shortened to the desired length, see above that when connecting the profile sections to a frame this already with the one running along its frame sections Glass sealing strip is provided. The previously required cumbersome process of subsequent cutting and Insert the glass sealing strip into the already finished one The frame can therefore be completely eliminated. To insert the It is now only glazing in the frame required that peelable masking tape be removed from the adhesive layer on the sealing surface of the glass sealing strip and the Glazing after setting in the frame on the Put the sealing surface on and press on, creating the seal the glazing on the frame has already been effected. Thus through Use of the glass sealing strip according to the invention significant simplification in the manufacture of windows and / or doors. But at the same time it becomes one improved positioning of the glazing in the frame, thereby reducing the support blocks to angled Adjusting the glazing results.

The adhesive layer on the sealing surface of the glass sealing strip can advantageously be made from a double-sided adhesive tape a thickness of 0.1 to 0.3 mm can be formed. Such Adhesive tapes are used as transfer adhesives, for example Rolled goods are commercially available and can be sold in large quantities inexpensive to manufacture the invention Glass sealing strip on the sealing surface of the sealing part apply.

To ensure that the glazing fits securely on the sealing surface of the To ensure glass sealing strip according to the invention, has the adhesive layer has an adhesive force of at least 15 N / 25 mm, preferably at least 20 N / 25 mm. That way on the one hand a firm seat of the glazing in the frame,  on the other hand also a good sealing effect between the Glass sealing strip and glazing manufactured. An adhesive on the is advantageous for the adhesive layer Base of an acrylate used.

Because of the locking part or the sealing part of the invention Glass sealing strip different functional The invention continues to propose requirements before that the locking part made of a rigid material with a higher shore hardness than the sealing part. By the higher rigidity of the locking part becomes a fixed and permanent locking in the slot of the profile allows while the softer sealing part with its lower Shore hardness a more flexible application on the Surface of the glazing as well as applying one for the Sealing effect required contact pressure allows. For this purpose, the sealing part advantageously has a Shore hardness of at most 68, while the locking part has a Shore hardness of has at least 72.

In a preferred embodiment, the locking part has a Shore hardness of at least 85, while the sealing part one Shore hardness from 55 to 65. Such Glass sealing strip with locking part and sealing part of the specified Shore hardening can be produced, for example, by that the glass sealing strip with a locking part from a hard set PVC and with a sealing part made of a soft set PVC of the specified Shore hardness by extrusion is made together.

The glass sealing strip according to the invention enables the combination of hard-soft material the recording or the Compensation for temperature-related shrinkage or expansion of the Frame.

To insert the glass sealing strip according to the invention in the receiving groove of the profile has a locking part Support bar to rest on the profile surface with a  one side of the support web protruding locking bar for Insert into the receiving groove of the profile. The locking bar is advantageously hollow and has at least one hook-shaped projection, which is approximately parallel to Footbridge extends to. The hollow design of the locking bar makes it easier to insert it into the slot because the Snap bar is so easy to compress while the protruding hook-shaped projections a latching of Cause locking bar in the receiving groove of the profile, so that permanent attachment of the invention Glass sealing strip is given in the profile.

In a preferred development, the sealing part also has a Hollow chamber on, which is above the locking bar extends opposite side of the support web. The Sealing part can, for example, by extrusion on the Support web of the locking part to be attached to this.

In an advantageous embodiment of the invention Sealing part on the longitudinal extension of the glass sealing strip running side edges of the support web of the locking part attached. The support web on one of the longitudinal side edges with an angled web equipped, and advantageously at the side edge that the outer sealing edge to the glass pane and weather side and lies outside the frame part.

Using the glass sealing strips according to the invention equipped with an adhesive layer, it becomes possible to carry out the following steps in the manufacture of such frames for windows and / or doors:

• a) Making profiles with grooves for the Glass sealing strips
• b) pulling in with an adhesive layer and masking tape equipped glass sealing strips in the profiles  
• c) Cutting the provided with the glass sealing strips Profiles on the profile sections corresponding to the frame
• d) connecting the corner areas of the profile sections into one frame
• e) pulling off the masking tape from the adhesive layer ( 315 ) of the glass sealing strips
• f) inserting the glazing into the frame and pressing on the glass sealing strips
• g) inserting glazing beads on the Glass sealing strips on the opposite side of the Glazing and fastening them to the frame.

Here are both profiles according to characteristic (a) for blind frames, casements, glass retaining strips.

According to the invention, it becomes possible to use the glass sealing strips already at the factory, d. H. in the manufacture of profiles in which To draw profiles for the frame and in this form to the to supply individual manufacturers. So that's one Significant labor savings and relief in Ready-made operation given that there is no separate one Storage for the glass sealing strips more required is and the operation of pulling the Glass sealing strips in the frame, namely for four Frame sides four glass sealing strip sections, d. H. four individual operations are eliminated.

Also insert the glazing in the with the Glass sealing strip according to the invention provided frame considerably simplified, since only the removable cover tape be removed from the adhesive layer of the glass sealing strip must and then the glazing can be used. The Adhesive layer provides a good seal and one adequate fixation of the glazing in the frame.  

This way it also becomes possible, contrary to the usual Manufacture of windows and / or doors during which Insert the glazing support blocks for the glazing are used one after the other along all frame sections, so that the glazing with these support blocks in the frame can be tensioned, this work process significantly shorten. Surprisingly, it turns out that using the glass sealing strip according to the invention of their adhesive layer that fixes the glazing is still required to support the glazing in the footprint, d. H. in the lower horizontal frame part of the frame on which the glazing due to its Dead weight after installing the window or door, to insert. In the remaining three frame sections there is one such blockage because of the gluing of the glazing the glass sealing strips are no longer required, so that again three operations in the manufacture of windows or doors by using the invention Glass sealing strip can be saved.

In a further advantageous embodiment of the invention also the glass retaining bar, which on the the stop bar of the Frame on the opposite side clipped into the frame and is in contact with the glazing, accordingly with a Glass sealing strip designed according to the invention become.

The glass sealing strip according to the invention is for profiles applicable from plastic, wood or aluminum. Here can be profiles as hollow profiles, also multi-chambered Hollow profiles or also as solid profiles, like wood, be trained.

The glass sealing strips can be used for sash frames or can be used for frames with fixed glazing. The glass sealing strip according to the invention can advantageously be used  for the mass production of windows such as Use cellar windows with single glazing.

A major advantage with the invention Glass sealing strip is reached is also an increased Burglar resistance due to the glass pane being glued together the glass sealing strip.

The invention is described below with reference to the drawings Exemplary embodiment explained in further details. Show it

Fig. 1 shows a cross section on an enlarged scale through a glass sealing strip according to the invention

Fig. 2 is a perspective view of a partial cross section through a window with a frame and casement and glazing with a glass sealing strip according to FIG. 1 in natural size

Fig. 3 is a schematic representation of a frame profile with inserted glass sealing strip before the glazing is inserted.

In Fig. 1 in an enlarged representation of the cross section of a glass sealing strip 3 according to the invention. The glass sealing strip 3 comprises a locking part 300 made of a plastic, for example hard PVC, with a Shore hardness of, for example, 96 and a sealing part 310 , which is likewise made of a plastic, such as soft PVC, with a Shore hardness of, for example, 62 consists. The glass sealing strip is produced by extrusion, the sealing part being extruded onto the locking part.

The latching part 300 has a support web 304 , on one side of which a projecting latching strip 301 is formed.

The sealing part 310 extends on the side of the support web 304 opposite the latching strip 301 , forming hollow chambers 312 a, b. For this purpose, the sealing part 310 is fastened with its two legs 311 a, 311 b to the longitudinal side edges 306 , 307 of the support web 304 of the locking part 300 by extrusion. The sealing part 310 also has a sealing surface 314 , which connects the two legs 311 a, 311 b of the sealing part 310 to one another. An adhesive layer 315 is applied to the sealing surface 314 . This adhesive layer 315 is formed by a double-sided adhesive tape which, for example, uses a nonwoven as the carrier material and is impregnated with an acrylic dispersion as an adhesive. On the adhesive layer 315, a peelable cover strip 316 is placed, which protects the adhesive layer 315th This masking tape can be formed, for example, by a siliconized masking paper.

The further features of the glass sealing strip 3 according to the invention are further explained below with the aid of FIG. 2. In this Fig. 2, a window is shown in a partial section through the lower horizontal frame part by way of example. The window has a frame 1 and a sash, frame 1 and sash 2 are made of multi-chamber hollow profiles made of a thermoplastic and are provided with reinforcing profiles 11 , 21 on the inside. In the closed state of the window shown in FIG. 2, the frame 1 and the sash 2 are mutually sealed by stop seals 10 , 20 inserted into corresponding receiving grooves 12 , 22 .

A glazing 4 is inserted into the casement 2 . The glazing rests on Aufstellklötzen 6, which are placed only on the mounting surface 25 of the lower horizontal frame member of the sash frame 2 shown in Fig. 2 and is on one side of an inserted into a guide groove 24 with a projection 52 glazing bead 5 with a in a receiving bore 50 inserted lip seal 51 sealed, while the sealing against the casement 2 is effected by the glass sealing strip 3 according to the invention as shown in FIG. 1. It is also possible to use a glass sealing strip 3 according to the invention instead of the lip seal 51 in the glass holding strip 5 .

The glass sealing strip 3 is fastened with its latching part 300 to the sash frame 2 in that the latching strip 301 of the latching part 300 is inserted into the receiving groove 23 of the sash frame profile 2 and the support web 304 rests on the sash frame 2 . In order to make it easier to insert the locking bar 301 into the receiving groove 23 , the locking bar 301 is hollow, as shown in FIG. 1, and encloses a cavity 302 . In this way, the locking bar 301 can be compressed somewhat when inserted into the groove 23 and can without much effort into the groove 23 engaged are. Furthermore, the locking bar 301 has two hook-shaped projections 302 which extend approximately parallel to the support web 304 and cause the locking bar 301 to be locked in the inserted state in the receiving groove 23 , so that the locking bar 301 is prevented from sliding out of the receiving groove 23 of the sash profile 2 . Since the locking strip 301, like the other parts of the locking part 300, is made of a rigid material with a Shore hardness of at least 72, a firm fit of the glass sealing strip 3 according to the invention is ensured in the receiving groove 23 .

On the other side of the support web 304 of the latching part 300 , the sealing part 310 rests with its sealing surface 314 on the surface of the glazing 4 and seals the glazing 4 against the casement 2 . The adhesive layer 315 applied to the sealing surface 314 , which is accessible after removal of the masking tape 316 , results in a firm connection of the sealing surface 314 with the surface of the glazing 4 , so that on the one hand a reliable seal is achieved and on the other hand the glazing 4 with sufficient strength is fixed to the sash 2 . Since the sealing part 310 is made of a soft PVC with a Shore hardness of at most 68, it is very elastic and pliable and can lay against the surface of the glazing 4 and at the same time a contact pressure on the sealing surface 314 which is desirable for increasing the sealing effect exercise.

To further increase the contact pressure over the entire sealing surface 314 , a reinforcing rib 313 is formed in the interior of the cavity surrounded by the sealing part 310 and the support web 304 , which divides the cavity into two parts 312 a, 312 b. The reinforcing rib 313 supports the sealing surface 314 against the support web 304 , so that an increased contact pressure can also be transmitted to the sealing surface 314 in this area. The reinforcing rib runs continuously in the longitudinal extent of the glass sealing strip and is wider with its support surface on the support web 304 than at the transition to the sealing part 310 , so that it cannot deflect laterally when the glazing 4 is pressed onto the sealing surface 314 . The stability of the reinforcing rib 313 can moreover be increased further in that it is not only molded onto the sealing surface 314 on one side, but is also attached to the support web 304 .

For a further increase in the contact pressure of the sealing part 310 on the sealing surface 314 , in particular in the critical area of the outer sealing edge 317 of the sealing surface 314 , the sealing surface 314 is inclined by an angle α with respect to the plane determined by the support web 304 . The angle α is approximately 3 ° to 10 ° and is oriented such that the outer sealing edge 317 of the sealing surface 314 is at a greater distance from the support web 304 than the inner sealing edge 318 of the sealing surface 314 . In this way, when the glazing 8 is placed and pressed onto the sealing surface 314, the further protruding outer sealing edge 317 is pushed back more strongly in the direction of the support web 304 , which is reflected in an increased contact pressure in the area of the outer sealing edge 317 .

To create the inclined sealing surface by the angle α, an angled web 305 is formed on the longitudinal side edge 306 of the support web 304 , at the end of which the leg 311 a of the sealing part 310 is extruded and thus the inclined position of the sealing surface 314 relative to that determined by the support web 304 Level.

In addition to the particularly good sealing of the glazing with respect to the casement profile 2 by the adhesive layer 315 applied to the sealing surface 314 , a very firm connection of the glazing 4 to the casement 2 is also brought about, so that the previously usual blockage of the glazing 4 along all horizontal and is necessary vertical frame portions Aufstellklötzen 6 stops, but it is perfectly adequate, only on the installation surface 25 on which the glazing 4 is resting as a result of their own weight to provide Aufstellklötze 6, whereby a substantial simplification of the manufacturing process for windows or doors is achieved. This manufacturing process is shown schematically in FIG. 3.

Analogously to the window shown in FIG. 2, a frame profile 2 a of a window or a door in the lower horizontal frame part is shown in detail in FIG. 3. The glass sealing strip 3 of the invention has been retracted already immediately after the manufacture of the frame profile 2 a in the receiving groove 23 and is fixed with its locking bar 301 and the projecting hook-shaped projections 302 in the receiving groove 23rd The adhesive layer 315 located on the sealing surface 314 is covered with a removable cover strip 316 .

The frame profile 2 a thus equipped with a glass sealing strip 3 according to the invention can now be assembled into a frame by cutting required sections and connecting the sections at their corners, but this is not shown in FIG. 3 for easier understanding. To insert the glazing, it is now only necessary to place mounting blocks 6 on the installation surface 25 of the lower horizontal frame part shown, on which the glazing will later rest due to its own weight.

To insert the glazing 4 , the cover strip 316 is then pulled off from the adhesive layer 315 on the sealing surface 314 of the glass sealing strip 3 in accordance with arrow P1 and the glazing 4 is placed and pressed onto the sealing surface 314 of the glass sealing strip 3 in the direction of arrow P2. Via the adhesive layer 315 there is an immediate connection and sealing of the glazing 4 and the frame 2 by means of the glass sealing strip 3 , so that the operations required for the production of windows or doors are made considerably easier. Suitable, mechanical devices ensure during this glazing process that the glazing is inserted and glued into the frame at an angle.

After the glazing has been inserted, it is now only necessary to carry out glazing beads 5 according to FIG. 2 on the side of the glazing 8 opposite the glass sealing strips 3 and to attach them to the frame. The all-round gluing of the glazing with the glass sealing strip 3 according to the invention then ensures the firm seating of the glazing in the frame.

By significantly simplifying the work processes at Manufacture of windows or doors using the Glass sealing strip according to the invention becomes a considerable one Cost savings possible, so that the invention Glass sealing strip especially for the production of Basement windows, windows for building shacks or containers as well Similar applications where it is as inexpensive as possible Window arrives, is suitable.
