Description

The invention relates to a seal for wall openings, such as window openings or door openings according to the preamble of the main claim.

In flood or avalanche danger, a major problem is that the water masses, snow masses or sludge masses can penetrate into the building interior through window openings or door openings. A sealing of these wall openings by normal blinds is not sufficient because the blinds do not close tightly and in many cases do not have the required stability to withstand the pressure acting on them.

The completion of wall openings, such as window openings or door openings to prevent access to a building interior, is a great need, for example, hunting lodges, holiday homes od. Like.

From the GB 23 05 453 A a seal for wall openings has become known, which consists of a frame which can be attached to the building wall, said frame is formed in cross-section U-shaped, so that in these U-profiles cover plates can be introduced to effect a seal. A special determination of the cover plates in the frame is not provided.

From the GB 23 66 825 A has also become known a sealing device for building openings, wherein retaining rails are provided, are used in the cover plates.

The cover plates are interconnected by means of toggle closures.

From the GB 22 43 393 A a sealing device for building openings has become known, wherein in cover rails inserted cover plates can be mounted from above by predetermined blocks with pressure.

The invention has for its object to provide a seal in which the actual cover plates can be fixed by insertable into the support rails clamping pieces and pressurized, so that thereby the required seal between the cover plates is reached.

This problem underlying the invention is achieved by the teaching of the main claim.

Advantageous embodiments of the invention are explained in the subclaims.

In other words, it is proposed that both sides of the wall opening C-shaped support rails are used, d. H. be attached to the wall and in these support rails one above the other individual cover plates, slats or other profiles are introduced, which connect with the interposition of a seal to each other. In this case, preferably, the width of the lamella is adapted to the guide slot of the retaining rail, so that a secure fixing of the lamella takes place in the support rails. The support rails in this case have a mounting flange which can be fastened by means of screws to the wall, said mounting flange can be aligned parallel to the blade, but also perpendicular to the blade so that thereby the mounting flange can be accommodated with the support rail, for example in the wall opening and can be set there and thus the attachment of the retaining rail is no longer accessible from the outside.

The determination of the slats in the support rails via clamping pieces, which are insertable into the support rails, the outgoing legs of the support rails are provided with a screening, preferably toothing and the clamping pieces also have a screening, preferably toothing, which cooperates with this toothing now z. B. by means of a screw clamping piece in the support rail is clamped. In addition, the clamping piece may also have a vertical screw which acts on the upper vertical flange of the lamella and now causes a sealed abutment of the lamellae one above the other by appropriate pressure application.

In other words, a clamping piece is proposed which has grids which can cooperate with corresponding counter-rasters on the profile element and thereby produce the positive connection between clamping piece and profile element. Furthermore, clamping means are provided in the clamping piece, whereby the actual clamping piece is anchored in the profile element by a frictional connection is made. The screening can be formed as a toothing or it can, for. B. cams are provided, which cooperate with corresponding holes or depressions of the counterpart. Also, a simple roughening be provided both on the clamping piece as the profile element, which acts as a toothing.

The serving for fixing the retaining rail bore may be formed according to a further feature of the invention as a so-called keyhole bore, d. H. the mounting screws are firmly attached to the wall and the support rails can now be placed on these mounting screws and pulled up or down and are determined by.

The lamellae are stepped at the upper end and have a horizontal flange, wherein this step-shaped design is also provided at the lower end and also a corresponding horizontal flange is provided here. In this case, the procedure is such that the lower end of the blade is set back by the amount that corresponds to the strength of the upper vertical flange. As a result, the slats partially overlap one another and lie with their horizontal flanges on each other, so that thereby a secure and stable connection the individual slats together. A z. B. provided in the lower region of the slats seal settles on the edge of the slat to be connected, so that there is a watertight sealing of the slats here.

To seal the wall opening is further provided that the bottom plate, which is inserted into the support rails, rests with the interposition of a sealing profile on the bottom surface. This sealing profile may for example be formed tubular and are mounted on the horizontal flange of the bottom plate, but it may also be a simple sealing profile, which is placed on the ground and on which the blade is pressed or which is fixed in a separate profile.

The support rails close with the interposition of a sealing strip to the masonry, so that penetration of water or fine snow is excluded in this area.

A complete seal can be achieved according to the invention further characterized in that jointing compound is introduced into the front region of the system of the lamellae on the support rails, but also in the lower region of the lowermost lamella such jointing compound can be provided.

The invention proposes that the support rails and the slats are preferably made of galvanized metal. Preferably, a galvanized slit strip is rolled for the slats, and the ends are folded to defuse the cut edges. Other materials are also possible.

In the drawings, 1 denotes a wall in which in. In Fig. 1 illustrated embodiment, a door opening 2 is provided. It is expressly pointed out that in the illustration in Fig. 1 the seal according to the invention is not used to illustrate the inventive concept beyond the actual door opening 2 out, but the representation in Fig. 1 should clarify how cover plates and support rails interact.

Furthermore, in Fig. 1 Support rails 3 and 4 are shown, are inserted into the cover plates, which are referred to in the following as slats 5. In the lower part of the seal formed from retaining rails 3 and 4 and slats 5, a sealing profile 6 is indicated.

The design of the individual components is clearer from the following descriptions of the figures.

In Fig. 2 is the support rail 4 recognizable, which - as clearly the Fig. 3 shows - C-shaped, wherein the free legs 14, 15 at their free edges a screening, preferably toothing 16 have.

In the guide slot 10 ( Fig. 3 ) Lamellae 5 are used, which are aligned substantially vertically and at the top End 28 are step-shaped, ie it is a vertical flange 22 and a horizontal flange 19 created. If the slats made of rolled slit strip, the upper vertical flange is doubled and also the horizontal flange 19 folded to defuse cutting edges.

The lower end 20 of each blade is also stepped and has a horizontal flange 21, wherein in this case the blade is set back by the amount that corresponds to the strength of the vertical flange 22 of the slat to be connected thereto. In addition, a seal 11 is rolled, which rests on stacked slats on the upper edge of the vertical flange 22.

In Fig. 2 is also recognizable that the support rail 4 - and the same applies to the support rail 3 - is provided on its back with a sealing strip 7, wherein a mounting hole 8 is formed, which - as clearly the Fig. 2 and the Fig. 5 shows - is designed as a keyhole. Here, the longitudinal axis of the mounting hole 8 can be aligned both vertically and horizontally.

The representation in Fig. 3 shows that the attachment of the support rail 3 - and the same applies to the support rail 4 - via a mounting flange 12 which is defined by one or more guided through the mounting hole 8 mounting screws 18.

In the illustrations according to the figures, the mounting flange 12 is always aligned parallel to the lamella 5. But it is obvious that it is also possible, the mounting flange Orientate 12 perpendicular to the blade, thereby inserting the mounting flange in the wall opening is possible, thereby access to the mounting flange and the mounting screw 18 is impossible for unauthorized persons.

To set the slats 5 in the support rails 3 and 4, close to the topmost plate clamping pieces 9, which in adaptation to the teeth 16 also have a screening, preferably toothing 17. This clamping piece 9 is fixed by screws 23 within the support rails 3 and 4, by the screw 23 is supported on the inside of the mounting rail and thereby inserts the clamping piece 9 with the toothing 17 in the teeth 16 of the free-running legs 14 and 15. In order additionally to achieve a clamping of the slats with each other, a vertical screw 24 may be provided, which leads with an external thread in an internal thread of the clamping piece 9 and acts with its free end on the upper edge of the vertical flange 22.

The drawing illustrates that the width of the slats, in particular the horizontal flanges 19 and 21, approximately corresponds to the width of the guide slot 10, so that the slats 5 are stored pretty tight in the guide slots and can not rattle and can hardly move.

An additional seal of the overall arrangement is achieved by the joint sealant 25 shown in the drawings. This joint sealant can be applied over the entire height of the support rails and the slats, but can also be provided in the lower region of the lowermost slat.

Instead of the joint sealant 25, it is also possible to equip the C-shaped support rail 3, 4 with seals that are fed into these rails, glued or rolled, these seals can be provided on both sides of the opening so that so the use of jointing compound would be avoided.

Not shown in the drawing is also the possibility that the lowermost slat is fitted with a special sealing profile before insertion into the support rails 3, 4, for example, a hose profile, which compensates for unevenness in the soil and thereby creates a watertight seal of the lower blade. The lower openings of the support rails 3 and 4 are also correspondingly tight, for example, by plastic plugs used od. Like. Also on-site seals are possible.

Not shown in the drawing is the possibility of forming the clamping pieces 9 also closable, d. H. to equip as a castle or with a lock, so that unintentional loosening of the clamping pieces of unauthorized persons is not possible.

By specially shaped angle clamps, it is possible to produce a positive connection for rectangular constructions.

One opposite the representation in Fig. 2 modified cover plate 5 is in the Fig. 6 and 7 shown.

This cover 5 according to Fig. 6 is bent in the upper and lower end of a U-shape and has an upper and lower horizontal flange 30, 31. At this horizontal flange joins in the upper and lower regions depending on a vertical flange 32, 33, the bent-back an upper and lower support flange 34, 35 carries. By this configuration, a particularly stable against water pressure element, ie a particularly stable cover plate is provided, wherein the defined by the vertical flanges 32 and 33 and the main surface of the cover plate width of the opening width of the support rails 3, 4 corresponds, so that the cover plates 5 also in this Embodiment firmly in the support rails 3, 4 are held.

In the horizontal flange 30, 31 upwardly directed bends 36, 37 are provided, which concave with stacked cover plates 5 together, so that here a positive connection between the individual cover plates is achieved.

In addition, the upper horizontal flange 30 and / or the lower horizontal flange 31, a seal 38 may be provided, wherein preferably this seal 38 is provided on the lower horizontal flange 31.

Fig. 7 shows an embodiment with which the resistance of the cover plate 5 can be additionally increased. In this case, a stabilizing blade 39 is provided, which has horizontal flanges 42 and 43 and in addition a pot-like bottom part 40, wherein this pot-like bottom part can be inserted into the space formed between the supporting flanges 34 and 35. This stabilizing blade 39 can be connected by screws or a weld with the vertical flanges 32 and 34 of the cover plate 5.

In the horizontal flanges 42 and 43 openings or holes 41 are provided through which, for example, reaching into the ground anchoring rods, which are not shown for reasons of clarity in the drawing, can be used.

If the sealing device used in a wall opening, the slats can be set in a holding rail, while the other holding rail against the slats is slightly movable, and then the keyhole holes are preferably aligned horizontally, so that precisely matched the overall arrangement of retaining rails and slats in the wall opening can be introduced, then a retaining rail is inserted so that both retaining rails can be connected with their keyhole to the corresponding screws and then the arrangement is determined by horizontal displacement.

ln the Fig. 8 to 10 Various additional embodiments of clamping pieces are shown and explained below, but what the invention is not limited. This in Fig. 8 shown clamping piece has a screening 16, which is formed in the illustrated embodiment as a toothing. The screw 23 allows a frictional fixing of the clamping piece 9 in the rail 3 or 4, in the Fig. 8 to 10 is not shown for clarity. Further holes for receiving clamping means, such as screws may be provided in the corresponding legs of the clamping piece 9.

The vertical leg of the clamping piece 9 is in Fig. 8 with 45 and the horizontal leg of the clamping piece 9 is denoted by 46, wherein the horizontal leg 46 extends transversely to the longitudinal extent of the male leg 45 to be received by the vertical leg or cover plate. In the same way it is also possible, as in Fig. 9 shown, the horizontal leg 46 to be aligned so that it extends parallel to the male in the vertical leg 45 slats.

In the training according to Fig. 10 extend the two legs in the same direction, so that here the connection of superimposed rails 3 or 4 is possible.

Other than the illustrated and described angular positions are possible and are within the scope of the invention.

The clamping pieces can be made of steel, non-ferrous metals or plastic.
