Abstract

The seal corner (1) has rubber and/or plastic film that is arranged between non-woven layers. The wall section (8) is arranged at right angle to step portion (10), during mounting state. The step portion is connected to a connecting portion (9) that is extended in an opposite direction to the wall section. The step portion is formed at the intended transition of wall portion, such that permanently visible material action of rubber and/or plastic film and/or non-woven layer is achieved. An independent claim is included for seal set for sealing sanitary fitting such as bathtub or floor-level shower tray.

Description

The invention relates first to a sealing corner for sealing a sanitary fixture such as a tub, such as a bathtub, a shower tray or a floor-level shower tray, in particular to a surrounding wall, possibly also surrounding soil, wherein the sealing corner based on a rubber and / or plastic film , optionally with a nonwoven layer, is formed and is flexible overall, further wherein the sealing corner has a usable in a given state of installation as a wall section and a section at least in the installed state at right angles to extending corner inside paragraph section has, further the wall section and the paragraph section of material into each other go over and beyond the integrally formed with the wall portion paragraph section further in one piece in any case in the installed state also angled to the paragraph section extending and with respect to the Absatzabschn ittes in opposite directions to the wall portion extending connecting portion passes.

The invention further relates to a sealing set for sealing a sanitary fixture such as a tub, such as a bathtub or floor-level shower tray, to a surrounding wall.

From the DE 100 31 214 B4 For example, a self-adhesive tape for caulking that can be folded on itself is known. A sealing corner of the type mentioned, but no fleece or knitted fabric is provided, is, for example, from the DE 295 21 668 U1 known. Furthermore, the state of the art on the DE 299 05 152 U1 to refer. From this, the sealing of a shower tray to the surrounding soil is known. A sealing corner is in terms of longitudinal and narrow edges of a bathtub, for example, or other sanitary Then usually combined with a sealing tape in the required length.

Especially with regard to the sealing of a tub shape to an ascending wall or optionally also surrounding soil, the known sealing corners and sealing sets are still not satisfactory.

Proceeding from this, the invention is concerned with the task of specifying a sealing corner or a sealing set, which is particularly favorable for sealing a trough shape with respect to an ascending wall.

A possible solution of the problem is given according to a first inventive thought in a sealing corner, is aimed at that one for forming the heel section at the intended transition of the wall section in the heel section in the rubber and / or plastic film and / or the nonwoven layer a permanent visible material effect is present. The permanent visible action of the material can initially facilitate an optional buckling in the installed state (the given installation state can also mean a flat alignment, ie without the use of the bend, irrespective of the presence of visible material action). The remaining visible material action can also be given in a pre-embossed curvature, which in any case in this area does not mean that the rubber and / or plastic film lies flat, optionally combined with one or more nonwoven layers, but in the given case, resting on a level surface , A lifting of the film, optionally with the one or both sides also provided nonwoven layer, a total of the ground means. However, the mentioned material action can only mean that there is a reduction in cross-section, which in the area of the action of the material does not lie directly on a flat surface Surface of the prepared sealing corner results, but otherwise leaves a continuous planar formation of the material, which is optionally formed in the installed state, if necessary only to the sealing corner, and not preformed in terms of a support on a flat surface in the sense of a total contrasting curvature.

A further possible solution of the problem is given in a sealing corner, in which it is geared to that the molded, integrally formed with the wall portion shoulder portion further integrally into one, preferably also angled to the heel section and, moreover preferably with respect to the heel section in opposite directions merges the wall portion extending connecting portion, the inwardly facing connecting surface is provided with an adhesive strip.

Preferably, the invention operates with a preformed edge in the film part, which is formed on the basis of the rubber and / or plastic film, optionally with one or more nonwoven layers on the outside, which may otherwise be present substantially flat. The film part ultimately forms in the installed state in an integral, material-uniform manner, the sealing corner. The user is thus given the transition from the wall section into the heel section by means of a pre-embossed or pre-formed crease line or, more generally, by using a permanently visible material action. In the same way, the connecting portion may be present in the form of a bend or as a whole. Such a sealing corner can still be sent and stored in a flat superimposition even when training preformed edges. On the other hand, the advantage of installation is given.

It may also be present in a development of a immediately three-dimensional design of the sealing corner, so that it already corresponds to the state of installation in the delivery state. In this respect, one possible solution is the task according to a further inventive idea given at a sealing corner, in which the molded, integrally formed with the wall portion shoulder portion further integrally merges into a likewise angled to the heel portion extending and with respect to the heel portion in opposite directions to the wall portion extending connecting portion. Here, an inwardly facing connecting surface of the connecting portion, as in the first described article, be provided with an adhesive strip, such as a butyl strip.

The molded-edge shaping can be given for example by deep drawing, optionally also at elevated temperature, ie thermally assisted deep drawing. It may also be a thermoforming as such, in which, for example, the total of heated to a deformation temperature sealing corner, or heated in the local area to a deformation temperature sealing corner, bent over an edge and / or pulled.

The abovementioned permanently visible material action can also be carried out in such a way that it essentially only has an effect in a then preferably unilateral nonwoven layer which is then preferably provided. Here, the fleece can be melted together as it were to a reduced level or compressed, optionally also pressed into the rubber and / or plastic film, be given. A certain effect on the underlying rubber and / or plastic film is certainly possible. Also in the sense of a certain thickness reduction of the rubber and / or plastic film. In a further preferred two-sided nonwoven layer arranged on the outside, this action on the nonwoven layer can be provided on both sides opposite each other. This results in one or both sides of a line of weakness, which can be installed on the surface with material present during installation with a low ausbildbaren thereby kink. Due to the indentation of the described design, preferably also with regard to the connecting portion, results in a predetermined design, which favors a correct application installation of the sealing corner. The formation of the sealing corner based on a rubber or plastic film, optionally with a nonwoven layer, nevertheless makes it possible to form the sealing corner in a freely foldable and bendable manner, for example even for packaging purposes directly superimposed on one another. Due to the molded geometry but immediately results in the handling of such a sealing corner for the purpose of installation the desired design.

The connecting portion and the heel portion in both embodiments integrally one piece, the same material, even in a corner center, into each other. Due to the indentation of the design or the edge formation, which does not affect the integral overall design of the sealing corner, there is no danger of a production-caused about leaks.

The arrangement of an adhesive strip, such as butyl strip, on the inwardly facing connecting surface of the connecting portion can be this low in the installed state with a vertical edge portion of a trough shape, such as at a bead, connect.

The aligned in the installed state on a horizontal paragraph section is preferably formed in the area of the center of the corner with greater extent to the interior of the corner as in more distant from the center of the corner areas. He can thus spans the resulting Freiraumzwickel between the tub corner and the corner center of the rising wall so low.

A further possible solution of the problem is given in terms of a sealing set in that there is a sealing corner with one or more of the Characteristics as described here for the sealing corner comprises and further comprises a sealing tape, which is suitable for flexibility for connection to a molded-in inner corner portion of the sealing corner. With such a seal set, a tub, for example in the form of a bathtub or floor-level shower tray, or another type of tub, can be conveniently sealed. The vote of the sealing tape on the sealing corner with molded inside corner section can ensure that on the entire sealed circumference, especially where an upstanding wall connects, a secure seal can be achieved. The indentation need not be provided on the sealing strip. Preferably, it is a planar in the initial state sealing tape, but due to the specified flexibility can invest on the connection area to the sealing corner at the molded-in paragraph section low and can connect by an adhesive also correspondingly tight.

Further features of the invention are described below, also in the figure description and the drawing, often in their preferred association with the concept already explained above, but they can also be assigned to only one or more individual features described or illustrated or independently or in any other overall concept.

Thus, it can also be provided that the heel section, with reference to a corner center, forms two preferably right-angled corner legs of different widths. In particular, a corner leg may be formed, which does not pass into a wall section. To seal this around a corner that merges into an ascending wall on one side, but on the other side into an adjacent flat floor surface, for example.

It is also possible to provide a plurality of edge formations, preferably next to one another and more preferably parallel to one another. Thus, with the same sealing corner, a different heel area can optionally be bridged to an ascending wall.

The sanitary fixture can also be an acrylic or steel tub, be it a bathtub or a floor-level shower tray. In addition to a conventional shower tray, which is formed in a known form with a raised edge opposite the adjacent floor.

Thus, it is preferred that the sealing corner is composed of a multilayer material. It is preferably a 3-layer composite. In this case, it is further preferred that an inner plastic layer and two nonwoven layers applied on both sides are provided. The plastic layer may consist of a thermoplastic elastomer. It can also be an NBR material.

With regard to a nonwoven layer, it may be, for example, a nonwoven based on a spunbonded fabric or a nonwoven fabric. In particular, it may be a water jet fleece. It may also be spun fibers consolidated with a binder. The fibers or the base material of the fleece are preferably made of polypropylene. However, it may also be, for example, polyamide or polyester.

Such a nonwoven layer can in particular also be equipped to block water. Here, a wax-based, for example, based finish or other hydrophobing agent may be incorporated into the nonwoven layer. The sealing strip, also in the mentioned 3-layer composite, is preferably formed with a small cross-sectional thickness. The total thickness can be 2.5 mm or less, for example, 1 mm to 2 mm, but also 0.1 mm to 1 mm, preferably about 0.5 mm to 0.9 mm, amount.

It is also preferred that a cross-sectional length of the connecting portion is greater than a cross-sectional length of the shoulder portion. Moreover, it is preferred that a cross-sectional length of the wall section is greater than a cross-sectional length of the connecting section.

The total width of the sealing corner, based on an installed state, ie the vertical height, can be, for example, 5 cm to 15 cm, preferably about 12 cm. For example, the connecting portion may have a dimension of 1 cm to 3 cm with respect to the said width, the wall portion may have a dimension of 7 cm to 12 cm.

The heel portion can have an extension in the direction of the center of the corner, again in the installed state, of a few millimeters, for example 2 mm to 8 mm, but also up to the centimeter range, for example 1 cm or 2 cm.

The heel portion is formed in particular in the corner center. It can also, based on a length of the sealing corner, in the installed state so in the horizontal direction, be provided expiring, d. H. be provided in a then common plane of wall portion and connecting portion temporarily.

The sealing corner may preferably be formed as a deep-drawn part. Here, starting from a surface piece, preferably in the three-layered training described, this surface piece can be placed in a corresponding thermoforming mold and embossed by stretching and / or temperature influence the corner shape described.

The adhesive strip, for example the butyl strip, is preferably also continuous in the center of the corner. The adhesive strip provides primarily the well-adhering connection between the connecting portion and the tub shape. In addition, however, in the finished installed state between the trough shape and the wall, for example, a tiling, yet another Verfugung with jointing compound, for example in the form of a Silikonverfugung made.

With regard to the sealing strip as part of the sealing set may be the same materials with respect to the material of the sealing strip, which are also specified in terms of the sealing corner. So the mentioned fleece formations or training of the plastic layer or combinations thereof.

With regard to the disclosure, the ranges and / or ranges of values or multiple ranges given above also include all intermediate values, in particular in one-tenth of the dimension, if appropriate also dimensionless, for example one step is one-tenth of a length, referred to one centimeter, ie one millimeter, where Further, an area (for a length) indicated by, for example, 3 cm to 5 cm is also disclosed in terms of 3.1 cm to 5 cm, 3 cm to 4.9 cm, 3.1 cm to 4.9 cm, etc. , on the one hand to delimit the mentioned range limits from below and / or above, alternatively or additionally but also to the disclosure of one or more singular values from the respectively specified range.

With regard to the permanently visible effects of material, for example the edge formations, it can also be provided that two or more intersecting material influences are formed. This has the advantage that a given due to the action of material transition between a paragraph section and a wall section can be used optionally can. Hereby, right / left arrangements can be formed with the same sealing corner. In particular, in the case that with respect to a corner region, a subsequent rising wall is given and is given with respect to another corner region a level adjoining floor.

With regard to a permanently visible material action, for example an edge formation, as such, it is also preferred for it to be continuous between two opposing peripheral edges of the shower enclosure. So it opens without interruption in each case in an edge of the sealing corner.

It is also preferable that the connecting portion regardless of the otherwise, d. H. outside a transition of the paragraph section in the connecting portion, if necessary, specifically provided permanently visible material action, always pre-embossed, based on an installed state of the shoulder portion downwardly projecting is formed. In this respect, with regard to transport or storage, it is not always possible to achieve an immediately planar layer formation of the sealing corner, but only such a (superimposed) layer formation with wrinkling or a three-dimensional superimposition. Often, however, the advantage given by this with regard to the predetermined orientation of the connecting section appears more important than the perfectly flat superimposition in the transport or storage state.

The invention also provides a sealing set for sealing a sanitary fixture such as a tub, such as a bathtub, shower tray or floor-level shower tray, in particular to a surrounding wall. It should be noted that a sealing corner is provided in the set with one or more of the features as described above with respect to the sealing corner, preferably with the features that a wall portion and a shoulder portion is provided, wherein the molded, integral with the wall portion formed paragraph section further integrally merges into an angled extending to the shoulder portion connecting portion, the inwardly facing connecting surface is provided with an adhesive strip.

Shown and described is a sealing corner 1 first embodiment, which can serve to seal a sanitary fixture such as a tub, in particular a bathtub, to a surrounding wall, in particular an ascending wall.

The sealing corner 1 consists, in particular in FIG. 2 illustrates, from at least one, in the embodiment, two nonwoven layers 2, 3 and on a nonwoven layer 2, 3 applied plastic layer 4. The plastic layer 4 is a middle layer in the embodiment. At the same time, it connects the two nonwoven layers 2 and 3, each forming an outer surface.

The sealing corner 1 is flexible overall, it can be folded on each other for example for packaging purposes. The sealing corner 1 further has a corner center 5, in which the immediate transition from a first longitudinal leg 6 is given to a second longitudinal leg 7, on. The corner center 5 is preferably preformed like a kink. It is a permanently visible material action in the sense of a pre-marked curvature. However, this crease-like preforming preferably does not penetrate the heel section 10, which will be explained below. In this case, the preforming is preferably interrupted.

Relative to a cross-sectional representation, as they are in particular FIG. 3 can be seen, the sealing corner on a wall portion 8 and a connecting portion 9. The wall portion 8 and the connecting portion 9 extend in the installed state and in the in FIG. 1 illustrated usual handling form rectified or approximately vertical. Between them extends as a transition said paragraph section 10, which is approximately horizontal with respect to the handling or installation.

The connecting portion 9 is further corner inside provided with an adhesive strip 11, which is formed in the embodiment and preferably as Butylstreifen.

A cross-sectional length L _{1 of} the connecting portion, compare in particular FIG. 2 , is greater than a cross-sectional length L _{2 of} the heel section. Preferably, the length L ₁ corresponds to one or more times the length L ₂ . For example, two to ten times.

Further, a cross-sectional length L _{3 of} the wall portion is greater than the cross-sectional length L _{1 of} the connecting portion. For example, the length L ₃ can be 1.2 to five times the length L ₁ .

The heel portion 10 is formed enlarged in the region of the corner center, so that the corner center 5 is less curved in the region of the connecting portion 9 than in the region of the wall portion 8.

The adhesive strip 11, in particular the addressed butyl strip, is preferably also continuous in the area of the corner center 5, as in FIG FIG. 1 indicated, trained. Preferably, it extends uninterruptedly over the entire length (when projecting into a plane of the sealing corner 1) of the sealing corner 1. The adhesive strip 11 is more preferably covered with a cover strip 12, which is removed prior to installation. This cover strip 12 may, as in FIG. 1 also shown, continuously, in particular in the corner center 5 continuously running, be provided. He can thus be deducted in one piece.

Related to the in FIG. 3 shown installation state that the sealing corner 1 by means of a sealing compound 13, which also serves as a primer layer, is attached. It may be about a polymer dispersion, z. B. an acrylate dispersion. This may also be enriched, if appropriate, with organic and / or mineral fillers. It can also consist of a plastic mortar combination. These are understood as meaning, in particular, mixtures of hydraulically setting binders (for example Portland cement) and additives. These mixtures may have mineral additives and / or organic additives and / or polymer dispersions as a proportion. It may further be an MS polymer (silyl-terminated polymers). In addition, this may also be bitumen or butyl, also an acrylate adhesive. The acrylate adhesive may also be formed as an adhesive strip, for example for processing on a roll. It is then, as it were, a double-sided adhesive tape, which, however, consists entirely of this acrylate adhesive.

The presentation of the FIG. 3 also applies to the preferred embodiment of the further seal with a sealing tape according to the sealing set. In this case, the shoulder portion 10 is preferably not pre-stamped contained in the sealing tape, but the sealing strip can be laid in this form due to its flexibility without further notice. The relocation is supported by the possible arrangement of the sound damping band 18 in the described form.

As a rule, the sealing compound is first applied to the wall and the sealing corner, especially here the wall section 8, is inserted or incorporated. The sealant then also continue to extend below the sealing corner wall side. The incorporation can also lead to the sealing corner, here the wall section 8, also front side coated with sealing compound.

On the sealing compound 13 or possibly also partially, directly on the relevant front side of the Abdichtecke 1, a tile adhesive 15 is applied, with the help of which then tiles 16 can be further attached to the front.

The arrangement of the sealing corner 1 with respect to an indicated here only in terms of their edge trough shape 16, it may for example be a bath or shower tray shape, is preferably provided such that the heel portion 10 is located approximately at a height of an edge top 17 of the tub shape.

Below the heel portion 10, the connecting portion 9 extends between the connecting portion 9 and the wall 14 is formed by the paragraph portion 10 a certain pocket, in which preferred and arranged in the embodiment, a Dämmmband 18 in the installed state. The sound damping strip 18 is also used in particular for sound decoupling, with respect to twill sound transmission. The sound barrier strip 18 may be connected directly to the manufacturing site with the sealing corner 1. But it can also, and this is preferred, be provided as a separate part, which is attached separately. It is preferred here first attached to the corresponding section of the sealing corner and the sealing corner then as a whole connected in the manner described with the wall. The attachment to the sealing corner may mean a bonding of the sound damping band 18 with the sealing corner.

On the front side or Eckinnenseitig the connecting portion 9, an adhesive strip 11, preferably formed as Butylklebestreifen arranged, as shown in the installed state according to FIG. 3 the immediate attachment to the edge of the tub shape allows.

Specifically, this is a downwardly facing leg of the rim of the tub shape, which forms an approximately vertical surface, which can be used for connection by means of the adhesive strip 11 with the sealing corner 1 meaningful and is usually used in this way.

A lowermost tile 16 is preferably arranged with a certain vertical distance v to the edge upper side 17 of the trough shape. This makes it possible to subsequently introduce a silicone bead 19 in the remaining gusset.

The vertical distance v can, what is not shown in detail here, installation by means of a spacer, for example, a foam part, be given, which is placed on the edge top 17 and thus inevitably the distance of the lower end face of the tile 16 to the edge top 17 of the tub shape 16 pretends. After such installation and tiling then the Schalldämmband can be removed again and the said silicone gasket 19 are introduced.

It is understood that for clarity the individual layers and layers in the figures, in particular in FIG. 3 , are shown exaggeratedly thick.

The processing of a sealing corner as described here and also of a sealing tape is preferably carried out in such a way that first the sealing corner 1 is attached to the trough mold 16, as in FIG FIG. 4 shown. In addition, the further sections of the sealing strip 20, preferably a sealing strip 20 in the form described, and optionally, if provided, a Schalldämmband 18. Then the so-equipped pan mold 16 is placed in place in the wall corner, if necessary also in a there already existing tub support, which may be formed as a foam tub support, for example, introduced. The tub shape can also be mounted in a known form on tub feet.

The wall can be previously or after the trough shape has taken said position, provided with the sealing compound 13, which is then applied to the upper side of the sealing corner or the sealing tape.

It then results in the state according to FIG. 5 , Then the tiling takes place, so that in the cross section then the state according to FIG. 3 ultimately yields.

Out FIG. 4 and especially FIG. 5 it can be seen that the heel portion 10 in the region of the center of the corner in plan view extends in a circular arc. In particular, as a result, the desired tight connection to the associated also circular arc or curved outer corner of the tub shape 16 is reached.

Related to the FIGS. 6 to 9 are sealing corners 1 second embodiment shown.

These sealing corners can be constructed in terms of material in the same way as the above-described sealing corners. 1

The sealing corners 1 second embodiment initially have different width paragraph sections 10, 10 '. The heel portion 10 'does not transition into a wall portion 8 even in an extension direction of the heel portions 10. However, it is unilaterally, in extension of an edge formation 21 between the wall portion 8 and the shoulder portion 10 via this edge formation 21 in the wall portion 8 via.

As can be seen in particular from the top view FIG. 7 and the rear view according to FIG. 8 results, a width b of the shoulder portion 10 'is chosen so large that it corresponds to a quarter or more of the cross-sectional length L _{3 of} the wall portion. The width b can also exceed the dimension L ₃ . For example, up to 1.5 or 2 times. The width b may in particular be equal to or greater than the sum of the cross-sectional lengths L ₃ and L ₂ .

A sealing corner second embodiment according to the FIGS. 6 to 9 serves to seal in particular a trough-shaped corner, which adjoins a straight running upstanding wall, but on the one side, on which the shoulder portion 10 'is formed, merges into a planar bottom region.

The sealing corner according to FIG. 9 serves to seal an opposite corner with the same configuration in terms of rising wall and flat bottom surface.

In reference to FIG. 10 a further sealing corner 1 is shown, in plan view, in which there are intersecting permanent visible material influences 21, 21 ', 21 ", 22. Reference numeral 22 indicates that even further permanently visible material influences, possibly also as pre-embossed edge formations, not like the permanently visible material effects 21 perpendicular to each other, may be formed. The multiple, preferably mutually parallel, permanently visible material influences 21, 21 ', 21 "allow the processor to vary the actual width of a heel section which may be formed in the installed state, and can optionally use one of the material influences to form an actual bend in the installed state ,

A sealing corner according to FIG. 10 is associated with the advantage that they both for training in the installed state of a sealing corner according to FIG. 6 as well as a sealing corner according to FIG. 9 can be used. The Eckausbildung in the wall portion can then be either by folding, which may be provided about the other permanently visible material effects 22, or by cutting the permanently visible material action 21, suitably up to about the intersection of the permanently visible material effects 21st

The sealing corner according to FIG. 10 is also associated with the advantage that it can be laid flat without the possibility of corner training.

In FIG. 11 is an edge formation, as preferred in any case in the embodiment of FIGS. 1 to 5 present, shown in more detail. The Kantenausformung is in the film from which the sealing corner is formed, pre-stamped. The cross-sectional representation can be seen that a significant bulge of the present material as a whole, so the rubber and / or plastic film, preferred and provided in the embodiment on both sides with a nonwoven layer (see in more detail approximately cross-sectional view of FIG. 2 ). This edge shaping of the FIG. 11 is shown singular, you can see here one of the two edge formations, which can be seen then are provided in opposite directions, to form the heel section 10 according to FIG. 2 correspond.

The edge shaping as in FIG. 11 is shown, as stated earlier, for example, be made by hot stamping or deep drawing.

In FIG. 12 is a permanently visible material action shown, which leaves a surface extension of the film or the rubber and / or the plastic film with double-sided nonwoven layer, substantially unaffected. As shown here somewhat exaggerated, only the nonwoven layers 2, 3 are significantly influenced, namely significantly reduced in thickness, while the rubber and / or plastic film 4 is unaffected or at least passed through substantially unaffected.

The material action according to FIG. 12 can be made by force and / or heat, for example with a rolling wheel or a blade-like part (without cutting through).

The edge shaping according to FIG. 11 is permanently formed in the material, so that although the sealing corner in the storage condition, such as FIG. 10 corresponds, can be laid essentially flat, but the installation state is then immediately given by the Kantenausformungen.

In particular, in the embodiment of the FIG. 10 , but also in the embodiments of the FIGS. 6 and 9 With regard to the transition to a wall section, a permanently visible material action, for example, as a pre-embossed edge formation 21, 21 ', 22, is provided continuously from a first peripheral edge 23 to a second, opposite peripheral edge 24 of the sealing corner.

In FIG. 3 It can be seen a free space F remained between the silicone bead 19, the adhesive strip 11, the sealing corner 1 and the sealing compound 13 and a portion of the tub 16. It may be limited in practice, if necessary, otherwise. Such a free space F can also continue, although possibly in a reduced cross-sectional extent, in the region of a subsequent sealing strip 20. In the case of a free-standing bath rim, this can sometimes result in an opening on the front side. It is preferable to fill a resulting opening thus the free space F, starting from the free edge of the tub, if necessary, with another filler. The filler may be a cord, for example a butyl round cord. This can be plugged over a certain length, for example, in the free space F.
