FLEXIBLE SEALING PROFILE, IN PARTICULAR FOR SEALING WINDOWS, DOORS OR THE LIKE.

The innovation concerns a flexible sealing profile, in particular for sealing between the stick frame and the casement of windows, doors or the like, with a section for insertion into a receiving groove, which on at least one side carries bendable projections.

15th

On the casement of a window or door, especially made of wood, plastic or metal, but also on container and hatch covers and the like, the casement has a circumferential groove which is used for receiving of the section of the sealing profile mentioned above is set up. The sealing profile has a second Section that protrudes from the groove and resilient and sealing against due to its inherent flexibility a surface of the associated stick frame, container or floor is applied.

The section inserted into the groove generally has longitudinal ribs on at least one side, which are the

art are inclined that they stand up when you try to pull the sealing profile across the groove from this pull out. This creates a clamping effect which reliably prevents the sealing profile pulled out of the groove during normal use.

The mentioned casement frames and the like are usually angular, so that the sealing profile consists of individual, straight profile strands is formed, which meet to form mitres.

Originally, only profile strands provided with a miter cut were inserted as sealing profiles, which at their ends rested against the miter cut surface of the adjacent profile strand. It has but found that a reliable seal without a tight connection of the miter cut surfaces is not was possible because the individual profile strands were cut with an exact final dimension or a slight undersize had to, in order to avoid that a profile strand the adjacent, adjoining profile strand from its Slot out.

In order to achieve a reliable seal, one then has the individual profile strands with the formation of Miters outside the frame are glued, welded or vulcanized to form a closed profile, wherein the length of the profile strands has been dimensioned such that a reliable seat of the sealing profile in the receiving circumferential groove was guaranteed. The sweat

The glue or vulcanization point was very clean because a thick connecting bead would have impaired the good seal.

In order to achieve an equally reliable seal with simplified assembly, molded corners have already been made Suggested rubber, which form a completely seamless miter and have such a profile that they merge flush with the adjacent profile strands.

When attaching the sealing profile, the molded corners are first placed, and then as Next, the extruded profile, cut exactly to fit, inserted between two shaped corners and with these butt glued. This glue point is necessary because the profile strand cannot be produced with oversize because otherwise it would push the shaped corners out of the groove in the casement.

With a rectangular casement, eight gluing points and four profile strands are required must be cut to fit so that the sealing profile can also be attached using Shape cornering is still very complex.

Based on this state of the art, the innovation is intended to develop the sealing profile mentioned at the beginning to the effect that that while ensuring a reliable sealing effect, attachment to a carrier such as about a casement is facilitated.

This object is achieved according to the invention in that at least some of the projections, which on the section are designed for insertion in a receiving groove, as separated in the longitudinal direction of the sealing profile individual projections which are arranged from one another and can be bent over at least towards this longitudinal direction are formed is.

These individual projections touch, as is also the case with the previous projections was the case, always a wall of the receiving groove; If a train is applied to the sealing profile in the longitudinal direction, then they bend thus the individual projections in the opposite direction to the pulling direction, whereby they tilt and / or squeeze each other, so that a longitudinal displacement of the sealing profile is effectively counteracted.

This amazingly simple measure makes it possible, for example, to design a profile strand in such a way that that once it is inserted into its groove, due to its inherent flexibility, it is in a exact final dimension can be pulled apart or compressed and then maintains this position. It is thus possible to cut parts of the profile strand according to the innovation with only rough dimensions, at the ends to be provided with a miter cut and then to be inserted into the receiving grooves in such a way that the miter cut surfaces collide just enough that they are close to one another, but not to one another Can push out the seat. In the same way, it is also possible to insert a corner between conventional shaped corners insert according to the invention formed profile strand, which is only roughly cut and then by pressing together or pulling apart is brought to an exact fit.

The innovation not only saves the amount of work previously required for precise cutting, but also ensures that even during the long period of use of the sealing profile this does not shift in its longitudinal direction, so that the full sealing effect is maintained. 35

In order to improve the holding effect of the sealing profile according to the innovation, the individual

projections arranged on two opposite sides of the sealing profile, wherein according to a further embodiment of the innovation advantageously the individual projections on one side of the sealing profile are longer than on the opposite side, so that they are as long as possible with full holding effect To achieve individual protrusions; because of the flexibility of these individual projections are therefore the requirements the dimensional accuracy of the receiving groove is particularly low, which conversely facilitates the insertion of the sealing profile according to the innovation in inaccurately dimensioned receiving grooves.

According to a particularly advantageous embodiment of the innovation, at least some of the individual projections are designed as cone-shaped knobs, whose Tips are preferably flattened. Due to the conical design, the knobs have a relatively

rigid foot, while the flattened tip of the knobs during a longitudinal movement of the profile insert between the foot and the associated inner wall of the receiving groove is expanded, so that a reliable Bracket is achieved. The tapered knobs are in in all bending directions equally effective, so that preferably separate, additional projections can be dispensed with, which to cause the sealing profile to be pulled out of the receiving groove.

According to a further embodiment of the innovation, the knobs are arranged offset from one another in the longitudinal direction, so that between the sealing profile and the associated wall of the receiving groove one distributed over the entire wall Support is established. At the same time, this design provides a good distribution of forces in the event of a load, so that overloading and giving way of individual knobs is effectively avoided.

According to a further embodiment of the innovation, the knobs are arranged close together, with 'at the' foot of the Knobs measured, the distance between two adjacent knobs is smaller than their diameter. Here the space between the individual knobs is dimensioned such that it excludes with certainty that in the event of a load, adjacent knobs mutually support each other hinder. In the case of a staggered arrangement, however, the knobs can also stand so close together that they fall a load in the longitudinal direction wedge itself with the following, offset knobs and thus the Increase the spreading effect.

Finally, the close-up arrangement of the knobs ensures that a relatively short section of the sealing profile effectively prevents its longitudinal displacement, so that not only the correct fit Insertion of a longer profile strand is facilitated, but also shorter, according to the innovation Profile sections can be used to seal a different type of profile strand between each other to pinch.

It is basically possible to have the foot diameter of the longer and shorter knobs essentially the same and then align the knobs on both sides of the sealing profile so they are flush with one another, to give the sealing profile better transverse rigidity. According to a further embodiment the innovation, however, it is advantageous that the foot diameter of the longer individual projections forming Knobs is larger than that of the opposite, shorter knobs in order to make them sufficiently flexible so that they contribute to the holding-spreading effect when the sealing profile is longitudinally loaded.

But at the same time the Ouersteifigkeit of the innovation according to To ensure the sealing profile, the number of shorter knobs is greater than that of the longer knobs, so that they are always supported across the profile by several shorter knobs. So it becomes prevents the longer knobs from being able to give way in their longitudinal direction in the event of a load.

Instead of the knobs or in addition to them, the individual projections can also form profiles, as they are, for example are known from shoe soles; According to preferred embodiments, this can be oblique comb-like elevations arranged to the longitudinal direction and / or around projections with open, suction cup-like depressions Act.

Finally, it is possible to have individual projections of different types on both sides of the sealing profile provide, for example, long knobs on one side and short, suction cup-like projections on the other side.

According to a further embodiment of the innovation, the individual projections are relative to a center line of the Profile foot arranged symmetrically, so that with longitudinal load ces sealing profile occurring - transversely to this directed resultant forces cancel each other, so that it is effectively prevented that the sealing profile is displaced in its position in the receiving groove.

As far as individual projections are provided which have a large width in relation to their height, such as for example in the case of the suction cup-like training, it is according to a further embodiment of the innovation of The advantage that the individual projections are undercut in the area of their foot, these undercuts advantageously transversely to the longitudinal direction

extend. As a result, the individual projections form to a certain extent flexibly attached to the profile foot Blocks / which tilt when loaded in the longitudinal direction and thus the sealing profile in its respective Lock the situation, so to speak. The preferred arrangement of the undercuts ensures that this tilting effect does not occur when the sealing profile is transverse to its longitudinal direction in the receiving groove is pushed in.

An advantageous embodiment of the innovation is, as already mentioned, is that the sealing profile at least least a profile strand extending essentially in a straight line, preferably made of extruded plastic includes ,, which is post-treated in order to be included in the profile strand, to introduce transversely extending depressions which separate the individual projections from one another.

However, according to a further embodiment of the innovation, it is also advantageous that the sealing profile a shaped corner formed from an angled profile strand is formed, which at the corners of a Window sash can be pressed into the grooves provided; because of the individual protrusions the shaped corners can only be moved with considerable effort in the respective longitudinal direction of the profile, so that a material connection between the corner of the mold and adjoining profile strand is not always required.

According to a further, particularly advantageous embodiment, a rectilinear corner closes at the shaped corner Profile strand without individual projections butt, with a conventional, commercially available profile as a profile strand can be used, which can be used particularly easily.

Here it is also possible to weld or glue the connection point between the molded corner and the extruded profile or to connect by vulcanization without the mold corner being stretched in any way during this work needs.

According to a further, but particularly advantageous embodiment The only innovation is the profile strand in its receiving groove between two shaped corners arranged at its ends trapped without being materially connected to it; due to the press fit between the profile strand and The molded corner is completely sealed without the molded corner being able to be displaced from its position. This refinement of the innovation enables the particularly simple and quick attachment: it is only for this purpose It is necessary to first apply the shaped corners to a frame and then subsequently cut the profile strands with plus dimensions, and these ι then to be pressed between the corners of the mold. The usage

On the one hand, to allow the widest possible use of commercially available profiles, and on the other hand To facilitate the insertion of the molded corners and to make their production cheaper, the legs of the Molded corners should only be long enough to ensure that they fit securely. According to a further embodiment As a result of the innovation, the shaped corner has a leg length of 8 cm, with the longer knobs

transversely to the longitudinal direction two are arranged, the opposite of the two following in the longitudinal direction, with the same transverse distance arranged knobs are offset by half a transverse distance, and of the shorter knobs in the transverse direction alternately three or four knobs are provided, which each have the same transverse distance and offset in groups one after the other by half a transverse distance are. Such a shaped corner has proven to be particularly advantageous and satisfies all of the above Requirements.

It is expressly pointed out at this point that under the profile insert according to the innovation not only the entire seal, but also a single corner is understood.

It is possible to produce the shaped corners from a profile strand in that two profile length sections are mitered together. According to a further, particularly advantageous embodiment of the innovation however, the molded corner is designed as an injection-molded part and is therefore largely free of shape particularly easy to manufacture.

The shaped corner according to the innovation is preferably formed from solid, preferably thermoplastic plastic; the massive training reduces the flexibility of the sealing profile in the transverse direction, so that at Force action in the longitudinal direction a secure clamping effect is achieved. The use of thermoplastic Finally, plastic allows - if desired, welding to the adjoining profile strand, what was not possible with the previously known molded corner made of rubber, and thus enables a simple, fabric-
