Description

The invention relates first to a soaked for delayed recovery foam sealing strip for sealing a used in a wall opening of a building object, wherein the foam sealing strip relative to a cross-section two opposite, respectively in the installed state of the inside or the outside of the building facing narrow sides and for attachment to the article or a soffit suitable broad sides, further wherein the foam-sealing strip has a partial longitudinal region and in the thickness direction of the foam sealing strip only partially connected to the partial longitudinal region part-longitudinal strips, wherein further the partial longitudinal region and the Part longitudinal strips made of the same foam and the foam sealing strip is permeable to air.

The state of the art is on the DE 10 2008 049 210 A1 to refer. In the case of the foam-sealing strip known from this, two strips, although of different widths, are juxtaposed arranged, which consist of different foam. From the WO 2009/138311 A1 It is known in the wound on the roll state to provide a folded area, which is achieved by a non-continuous separation section in the thickness direction. For installation, however, this partial longitudinal strip is folded over in the installed state to achieve a different vapor diffusion value or different airtightness with respect to the narrow sides.

Based on the cited prior art, the invention has the technical problem of providing an advantageous foam sealing strip, which is both inexpensive to pack as well as a high variability in terms of installation allows.

A solution of the indicated technical problem is provided by a foam-sealing strip according to claim 1, whereby by placing the partial longitudinal strip on the partial side region of the thus formed side region in the installed state due to higher compression in the support area is denser than the opposite side area. Such a configuration initially also allows installation without respect to the side regions of different vapor barrier effect. In addition, the embodiment allows installation with a at the the doubling by, for example, folding narrow side higher compression higher vapor barrier effect or a higher airtightness. In particular, the higher vapor barrier effect or higher airtightness can be achieved solely by the higher compression. In addition, such a foam sealing strip in the rectangle output state can be wound up to the role.

Advantageous embodiments will be apparent from the dependent claims.

The foam is preferably an open-cell flexible foam. For example, a polyurethane foam. The open cell nature can be characterized by an air permeability. The air permeability may for example be in the range of 20 to 1000 l / m ² s, preferably 20-500 l / m ² s or 20-250 l / m ² s, more preferably 20-150 l / m ² s or for other applications in the range of 50-200 l / m ² s, measured according to DIN EN 9237 on a 10 mm thick sample at 0, 5 mbar negative pressure, sample area 100 cm ² . The measurement can be carried out with a Frank device, for example the Frank device type 21443. The foam may have a density of, for example, 25 to 100 kg / m3.

With regard to the characterization that the foam of the partial longitudinal area and the partial longitudinal strip is the same foam, the background is that a uniform foam strip may be chosen as the starting material. The cuts are then made in this uniform foam strip. In particular, in embodiments which have a continuous cut with respect to the foam itself, although preferably the same, that is uniform, for example, polyurethane foams are preferably selected with the same air permeabilities, but not necessarily derived from the same block foam strips used.

Preferably, one of the at least two longitudinal incisions of the sealing strip is designed to form at least one partial longitudinal strip, which is easier to fold over due to the incision. This incision may be spaced from the narrow side (longitudinal side surface) of the sealing strip by 0.5 to 5 times or 1 to 3 times the thickness of the foam sealing strip with respect to the fully restored state and the output rectangular state , optionally also about 0.5 to 10 times the same.

In a further embodiment, according to a first alternative, it is preferred that the partial connection between the partial longitudinal region and the partial longitudinal strip by means of one of the two longitudinal incisions is given by the fact that this longitudinal incision only over a portion of the thickness of the foam Strip stretches. The foam sealing strip is thus preferably made of an initially integral uniform, rectangular foam strip formed having a corresponding incision. More preferably enforced by Nick also immediately the one broadside completely covering (first) self-adhesive layer.

In a further embodiment, it is also preferred that the first broad side, which is preferably completely covered with a (first) self-adhesive layer, has a cover layer. The self-adhesive layer may also extend only over a part of the first broad side, for example only over a part of the width of the partial longitudinal strip or not over this. The self-adhesive layer preferably extends over the entire width of the partial longitudinal region or over only a part of the width thereof.

At least one of the two incisions on the first broad side of the sealing strip preferably passes through the self-adhesive layer on this broad side, the incision (for example one of a plurality of this broad side) can also be introduced into the foam material next to the self-adhesive layer. Preferably, the incision (first incision) also passes through the cover layer of the self-adhesive strip. The cover layer may in particular be formed as a film or paper web, for example made of silicone paper. According to a modification, the self-adhesive layer and / or cover layer on the first broad side of the sealing strip is not severed, for example, the transection can be done on site. For this purpose, for example, the self-adhesive layer (preferably together with the cover layer) can be applied to the already provided with the (first) incision sealing strip. This may be advantageous under certain circumstances, since then provided with one or more incisions sealing strip has a greater stability and is easier to handle on site.

According to the invention, two (ie at least two) or more incisions, spaced apart in the width direction of the foam sealing strip, are formed. This allows a (at least) double doubling or multiple layer duplication in the installed state, so as to achieve an even higher vapor barrier effect and / or higher humidity at the respective side area in the installed state and / or the installation width of the foam sealing strip low on different widths objects For example, different width roller shutter boxes to adapt. The cuts are preferably spaced from one another 0.5 to 5 times or 1 to 3 times the thickness of the foam sealing strip with respect to the fully restored state and the output rectangular state, and optionally also 0.5 to 10 times , The distance of a first cut from the associated narrow side is preferably equal to the distance between the first and second cut as described in the same way and the same dimensional bandwidth provided. The total width of such a foam sealing strip in the rectangle output state may be, for example, 5 to 40 cm. The thickness may be between 0.5 and 10 cm in relation to said initial rectangular state and the fully restored state.

It is also according to the invention that the second longitudinal incision is formed in the opposite direction to the first longitudinal incision. Thus, while the first longitudinal incision is made starting from a first broad side of the foam-sealing strip, the second longitudinal incision may be formed starting from the opposite second broad side of the foam-sealing strip. This includes that more than two longitudinal incisions are also formed alternately in opposite directions to the respectively adjacent longitudinal incision. Preferably, the second longitudinal incision is not made continuously.

The foam sealing strip is preferably designed such that the (at least) second longitudinal incision does not sever the self-adhesive layer. If more than two longitudinal cuts are provided, then is preferably the second of two adjacent longitudinal incisions the self-adhesive layer is not formed by severing.

It is also preferred that a longitudinal incision does not sever the covering layer. A longitudinal incision can enforce the foam sealing strip in terms of its thickness, for example, to 60 to 99% or 55-95% or 50-90%.

The invention comprises a foam sealing strip in which a first broad side is completely provided with a self-adhesive layer.

Furthermore, it is alternatively or additionally preferred for a second self-adhesive layer to be provided on the first broad side of the sealing strip opposite the (first) self-adhesive layer formed over the entire broad side of the sealing strip, the second self-adhesive layer only over a part of the width of the second Broadside extends. Preferably, the second self-adhesive layer extends over a portion of the width of the partial longitudinal region, the second self-adhesive layer may also extend in combination therewith or independently thereof across part or all of the width of the partial longitudinal strip. Optionally, the self-adhesive layer may extend over only part or all of the width of the partial longitudinal strip.

The second self-adhesive layer in the width direction of the foam-sealing strip between two longitudinal incisions is preferably formed on the foam-sealing strip according to the invention.

In the context of the invention, alternatively or additionally, the sealing strip may alternatively or additionally have the second self-adhesive layer or another connecting layer arranged spanning a longitudinal cut in the width direction of the foam sealing strip.

On the foam sealing strip according to the invention, the partial connection between the partial longitudinal region and the partial longitudinal strip can generally be longitudinally passed through a longitudinal extent of the foam sealing strip and the foam of the foam sealing strip over the entire thickness (d) Be formed.

In particular, it is also preferred that the second self-adhesive layer or another connecting layer is arranged spanning a longitudinal cut in the width direction of the foam sealing strip. This in particular concerning the embodiment with complete separation of the foam. The second self-adhesive layer or the bonding layer then acts in this area as it were also as a hinge. The connection layer can be, for example, a fleece or fabric layer or film. The connection layer is preferably a non-foam layer. The connection layer is not an integral part of the foam sealing strip and is preferably made of a different material than this.

Moreover, it is also preferred that all longitudinal cuts are provided throughout the foam. In the case where two self-adhesive layers are formed opposite one another with respect to a longitudinal incision, it is also preferred in this context for one of the self-adhesive layers to be severed, but not the other.

The partial longitudinal region of the foam sealing strip particularly preferably has a rectangular cross section, preferably the sealing strip as a whole. The sealing strip is thereby particularly simple and dimensionally accurate to produce, so that the water-diffusion resistance of the folded sealing strip can be accurately determined. If appropriate, the partial longitudinal region and / or the at least one partial longitudinal strip may also have a non-rectangular cross section. For example, the partial longitudinal strip may have a non-rectangular cross-section, for example wedge-shaped or otherwise profiled (for example wavy), wherein the partial longitudinal region of the sealing strip preferably has a rectangular cross section, but for certain applications may also have a different cross section, for example, also wedge-shaped (or wavy). The wedge-shaped cross-sectional area can taper to the adjacent narrow side of the sealing strip or optionally also expand. In this way, the accumulation of material and thus also compression of the folded foam sealing tape at the respective cross-sectional area can be adapted to the respective requirements, in particular with regard to the water vapor diffusion resistance. With regard in particular to the foam roll-up strip wound in the form of a roll, the features already described above or otherwise generally within the scope of the invention concerning the foam-sealing strip are preferably provided as such.

Preferably, the first broad side is provided with a self-adhesive layer, which extends over a larger area of the sealing strip than the second broad side. For this purpose, the first broad side may, for example, be provided with such a self-adhesive layer over the whole area or at least in the area of the longitudinal area over its full area. In this case, "full area" is preferably continuous throughout, optionally also "distributed over the whole area", e.g. full area with interposed not provided with self-adhesive layer areas.

Preferably, the sealing strip is formed such that the partial longitudinal strip is folded over to the second broad side, ie on the broad side with a lower self-adhesive surface. The longitudinal cuts are to be set accordingly. After a modification, if necessary, the partial longitudinal strips can also be folded over to the first broad side. The first broad side is usually attached to the corresponding component such as a frame member (eg window or door frame). For this purpose, then the top of the partial longitudinal strip (which is folded after folding then to the first width page) be provided with a self-adhesive area, optionally (although less preferred) but not if, for example, the width is sufficiently low so as not to affect the attachment of the sealing strip to the component.

With regard to the disclosure, the ranges given above and below (of dimensions or relative variables, for example) also include all intermediate values, in particular in 1/10 increments of the respective dimension, if appropriate also dimensionless, for example 1/10 mm steps, on the one hand for delimiting said range limits from below and / or above, alternatively or additionally but with regard to the disclosure of one or more singular values from the respective range.

Shown and described, first with reference to Fig. 1 , A wound in the form of a roll 1 foam sealing strip 2. The foam sealing strip 2 consists of an open-celled and delayed to delayed recovery soft foam.

The foam sealing strip 2 has a first broad side 3 and a second broad side 4. The first broad side 3 is provided with an over the entire width extending self-adhesive layer 5. On the second broad side 4, a second self-adhesive layer 6 is applied, which, however, extends only over a partial area (width dimension T) of the width B of the foam sealing strip 2. The first and / or second self-adhesive layer 5, 6 is preferably reinforced by an inserted thread grid.

The foam sealing strip 2 also has a first narrow side 7 and a second narrow side 8.

The second self-adhesive layer 6 is arranged both at a distance a in the width direction to the first narrow side 7 as with a distance b to the second narrow side 8. It is preferred that the distance b to the narrow side 7 is greater than the distance a to the narrow side 8. The distance a may, for example, 1 to 5 times a thickness d of the foam sealing strip (based on a non-duplicated area) be. The distance b can, for example 5 to 30 times the thickness d. This can generally apply in the context of the invention.

The second self-adhesive layer 6 may also be provided with a cover layer 9, just as the first self-adhesive layer 5 may be provided with a cover layer 10. The cover layers 9,10 cover at least the entire width of the self-adhesive layer 5,6.

The foam sealing strip 2 also has two longitudinal cuts 11, 12. The longitudinal cuts extend over the entire length of the foam sealing strip. Preferably also over the entire length with the same depth t ₁ or t ₂ , see also Fig. 2 ,

The longitudinal incisions 11, 12 divide the foam sealing strip 2 into a partial longitudinal region 13 and two partial longitudinal strips 14, 15. A partial longitudinal strip 14,15 is preferably formed with a smaller width than the partial longitudinal region 13. In addition, both partial longitudinal strips 14,15 are preferably formed with the same width. In the exemplary embodiment, the width of the partial longitudinal region results from the total width B minus twice the width c. The first longitudinal incision 11 is after FIG. 1 However, according to another, most preferred, embodiment of the longitudinal incision 11 cuts through the self-adhesive layer and / or the cover layer (not shown), particularly preferably both layers or Layers, so that the longitudinal strip can be folded directly on site and not first the cover layer and / or the self-adhesive layer must be severed.

As in Fig. 3 shown, the foam strip 2 can be placed according to the first longitudinal incision 12 in a first unfolded position. The thus formed second narrow side 8 'has correspondingly practically a double thickness compared to the opposite narrow side 7. The doubling achieved by the two partial longitudinal strips 14, 15 in this embodiment, but also only from a partial longitudinal strip 14, optionally with a corresponding larger width, possibly so twice the width as they are approximately in Fig. 2 is shown, preferably extends in the cross section shown over half of the width B 'of the thus formed, ready for incorporation foam sealing strip. More preferably, an extension is over one third to two thirds of the width B '. This first open position thus creates a visible side area of the foam sealing strip configured in this way, which in the installed state - assuming a joint width that is the same throughout in cross-section - has a denser construction than the opposite side area.

Another possible design is in Fig. 4 shown. In this case, the first narrowing of the two longitudinal side strips 14, 15 is according to FIG. 1. In this embodiment, first of all a first folding over of both longitudinal side strips 14, 15 is provided Fig. 3 in which case the longitudinal side strip 15 is again folded back onto the longitudinal side strip 14. This has the effect that the longitudinal side strip 14 is connected to the longitudinal part 13 only by a self-adhesive layer, the self-adhesive layer 6, However, the partial longitudinal strips 14,15 are connected to each other by a double-layer self-adhesive layer.

In addition, in this constellation it is also preferred that the narrow side 8 "is also externally provided with a self-adhesive layer over part of its height, over a further part of its height, here formed by the topmost layer due to the partial longitudinal strip 14, but not with one Edge cover is covered according to a self-adhesive strip.

The Fig. 5 shows a possible installation of such a foam sealing strip on a roller shutter box 16. The roller shutter box is known to have a much greater width compared to a window frame (dimension in the depth direction, so based on a conventional installation, the horizontal dimension from outside to inside), so that the width B or B 'of the foam-sealing strip can be provided adapted thereto. The multiple preferred provided longitudinal incisions 11,12 also allow in this regard an adaptation (possibly also as by separation at the longitudinal incisions). Preferably, however, in this embodiment, the use of one or more of the partial longitudinal strips 14, 15 for adaptation to the width of a joint (dimension in the height direction of a wall).

With regard to the further possible applications mentioned further above, an adaptation to the width of the window or the blockhouse wall element would accordingly be given, but in particular also adaptation to a joint width in these other applications.

The Fig. 6 Finally, indicates the installation state of such a sealed up against a window reveal 17 shutter box. The representation is not to scale to compare with the representations of the foam sealing strip alone. Assigned to an interior 18 is by the triple layer of the foam sealing strip in. Installation state in this side area achieved a much higher compression than the outside. The seal is accordingly, as required by the regulations inside denser, so leads inside to a higher vapor-tightness. The foam sealing strip still has an expansion reserve over its entire width in this installed state. The air permeability of the sealed joint is ≤ 0.1 m ³ / [hour x meter (daPa) 2/3] according to DIN EN 1026.

In reference to Fig. 7 is a wound up in the form of a roll 1 foam sealing strip 2 second embodiment shown.

The same reference numerals as in the first embodiment mean a same embodiment, so that reference is made to the explanations there. The second embodiment according to the FIGS. 7 to 11 differs first of the first embodiment in that with respect to a longitudinal incision 12 which completely cuts through the foam, a second self-adhesive layer. 6 opposite to the first self-adhesive layer 5, the longitudinal recess 12 is arranged spanning in the width direction of the foam sealing strip. The second self-adhesive layer 6 can be seen to be continuous, also with regard to the cover layer 9 (in the width direction). It can, therefore, how about from the Figures 10 and 11 results, according to a hinge allow a relevant Aufklappung for doubling the foam strip. The same applies to a spanning connection layer of another material, such as a nonwoven fabric or the like.

Further, with respect to this second embodiment, the further longitudinal incision 11 is formed continuously with respect to the foam. But not with respect to the self-adhesive layer 5 and its cover layer 10. Accordingly, this also arises in this regard, such as from Fig. 11 shows a hinge function of the self-adhesive layer 5.

The representations of the Figures 10 and 11 with respect to the doubled state, in particular with regard to the in Fig. 10 shown column in the region of the longitudinal incision 11 and seen from the narrow side 8 'beyond the here then double-layer given self-adhesive layer 6 are exaggerated for the purpose of a clear representation. In practice, this is essentially an immediate investment.

In Fig. 12 a further embodiment is shown in which the partial longitudinal strips 14,15 are provided on both sides of the partial longitudinal region. It is here apparent to the initial state, for example. The state as it is in wound form in the roll.

Accordingly arise here on both sides of the Aufdoppelungsmöglichkeiten, as in the Figures 10 and 11 are shown. However, only one page can be doubled or not on one side the condition according to Fig. 10 be prepared and on the other hand the condition according to Fig. 11 ,
