Description

The invention relates to a sanitary sealing element having a first portion and a second portion, wherein the sealing element is provided to sealingly connect a sanitary object with an adjacent wall and / or bottom surface.

In particular, the sanitary sealing element is to be arranged at the corner of a sanitary object in the form of a bath or shower tray or even a carrier or carrier system for such a sanitary tub. The then arranged at a corner of the sanitary object sanitary sealing element can be combined with conventional sealing tapes to ensure a reliable seal of the sanitary object. As a rule, a peripheral frame is formed with a plurality of sanitary sealing elements and sealing tapes connected to one another, which then ensures a complete seal by the connection with a sanitary tub or a sanitary tub support system.

Very high demands are placed on the sealing of a sanitary object exposed to water, in order to permanently and reliably prevent the escape of water. Absolute watertightness must be guaranteed not only immediately after installation, but also over the long term.

To seal sanitary objects against wall corners, a simple sealing tape can be used, as can be seen from the DE 100 31 214 A1 is known. However, if a sanitary object in the form of a shower tray, a bathtub or a tub support system to be connected to a flat floor surface, so must be superimposed at the corners sealing strips and interconnected, so that there is an increased risk of leakage.

Accordingly, for example, from the DE 299 05 152 U1 preformed sanitary sealing elements with which a sanitary object in the form of a bath or shower tray waterproof can be connected to an adjacent floor surface. The sanitary sealing element in this case has a first portion which can be fixed with adhesive to the edge of a sanitary tub, in particular a shower tray. In the usual installation situation, the first section is aligned vertically and extends on the outer periphery of the sanitary object over corner. A second L-shaped flat section connects to the first section via a bend, with which the sanitary object can be connected to a flat floor surface ( 1a of the DE 299 05 152 U1 ). If a floor surface joins the one leg of the sanitary object and a wall surface on the other leg, the preformed sanitary sealing element can be folded accordingly ( 1b of the DE 299 05 152 U1 ).

Finally, individual sanitary sealing elements - possibly together with a common sanitary sealing tape - can be formed into a peripheral frame ( 5 of the DE 299 05 152 U1 ).

The known system has proven itself in practice, because it is thus no longer necessary that a simple sealing tape on the construction site is freely pieced together and glued by a fitter.

In order to bridge steps and paragraphs, gaps and clearances and compensate, sanitary sealing elements can also be preformed with appropriate paragraphs and steps, with such a sanitary sealing element for the arrangement in a wall corner EP 2 774 516 A2 is known.

The known sanitary sealing elements and sanitary sealing tapes frequently have a carrier layer, in particular a film and a cover layer of nonwoven fabric. Such laminates have a certain flexibility and stretchability, but the geometric adaptability is limited. Especially with dimensional deviations, assembly inaccuracies or a setting behavior after assembly is locally and in particular at corners often the need for compensation. If such deviations and inaccuracies can not be compensated by the mobility of the sanitary sealing element, uneven installation, wrinkling or even tearing of the sanitary sealing element can not be safely avoided.

Against this background, the present invention seeks to provide a sanitary sealing element, which is characterized by a particularly good handling and allows a far-reaching compensation of deviations and height differences just at corners.

The invention relates to a solution and the problem is a sanitary sealing element according to claim 1. The invention further relates to a sanitary installation with a sanitary object and with the sanitary sealing element according to the invention.

Accordingly, the invention relates to a sanitary sealing element having a first portion and a second portion, wherein between the sections by a pocket-shaped material supply a spatially limited by ends and preferably angled or curved in plan view extending movement fold is formed and wherein the decreases perpendicular to the course of the movement fold certain length of the pocket-shaped material supply starting from a central region of the movement fold along its course in the direction of the ends.

The length is to be determined perpendicular to the course of the movement fold, for example, based on a cross section and on the other hand results from the maximum range of motion, which is available for a shift of the two sections.

Preferably, the length of the pocket-shaped material supply decreases continuously, in particular evenly, starting from the middle region. If, for example, the movement fold has an angled shape in plan view, then a maximum displacement between the first and the second section can be achieved exactly in the middle of the movement fold along its course, in which case a triangular gusset is formed at the height offset from the middle area to the ends.

The first portion and the second portion may each form an L-shaped surface or connect to each other at least at an L-shaped connecting line.

Within the scope of such an embodiment, the movement fold is then located on a section of this connection line. Outside the movement fold, the two sections can then merge directly, via an angling or a step.

In the context of the invention, an L-shaped designation is a profile with two legs which adjoin one another at right angles or at least approximately at right angles. The length of the individual legs should be insignificant. Of course, the L-shape is only mentioned as an example, although other angular orientations and arcs may be considered.

Although the movement fold has an L-shape, so the two legs can be carried out in particular the same length. In an L-shaped configuration of the movement fold in a plan view, the two legs are usually not connected by a sharp bend but by a radius, wherein the movement fold can basically also run as a bow. In any case, other shapes such as a straight course or a structure with branches are possible. In particular, the movement fold can be designed T-shaped depending on the application with three legs.

As already explained above, the greatest freedom of movement results in the middle region of the movement fold. By the movement fold the sections are movable over a height h against each other, wherein the height h, so the maximum stroke between the two sections may be for example between 5 mm and 50 mm. If one of the sections is arranged, for example, in a middle position, then the other section can be adjusted starting from the specified height range between +/- 5 mm and +/- 50 mm.

In order to process the sanitary sealing element well and in particular to be able to glue, according to a preferred embodiment of the invention, the first section and the second section are at least partially covered with a textile covering material, in particular a nonwoven fabric. On at least one side of the sanitary sealing element, such a covering material can be placed over the entire surface, wherein the area of the movement fold is to be omitted. Often the cover material is used in the sanitary sealing element on both opposite sides.

According to one embodiment of the invention, it is provided that the sanitary sealing element has different nonwoven blanks, which are applied separately from each other. It is then also possible to arrange on the first section and the second section nonwoven blanks with different fiber orientation and / or different fiber structure. In the context of the invention, a different fiber structure can also be achieved by forming the nonwoven fabric from a plurality of layers, wherein different fiber types and / or different fiber orientations are then used within these layers.

Fiber orientation often results in non-woven fabrics with an anisotropic elongation behavior. Even if the nonwoven fabric is formed from long fibers or continuous fibers and these have a designated preferred direction, the nonwoven fabric along the fiber longitudinal direction is relatively stiff and transverse to this easier to stretch.

While relatively large steps, unevenness and dimensional deviations can be compensated within the scope of the invention for the movement fold, a certain expansion and mobility of the two sections can also be achieved by a specific selection and arrangement of the nonwoven blanks. A low extensibility in different directions, for example, is achieved when the nonwoven fabric is formed of multiple layers with different fiber orientation.

The textile cover material can outside of the movement fold on at least one side of the entire surface be arranged. It then results in a closed, continuous surface, which also allows a complete bonding.

In order optionally to allow easy folding or even a residual expansion, the textile cover material may be provided outside the movement fold between the first and second sections and / or within at least one of the sections with a perforation. For example, the second portion may be formed so that it can be fully connected to a bottom surface or alternatively also a bottom surface and an adjacent wall surface. From a substantially flat arrangement in the connection exclusively with a bottom surface, a part of the second section is folded up for connection to a wall surface, for which purpose the perforation can serve as a bending line. Depending on the requirement, a plurality of perforation lines can also be formed next to one another and / or with an offset of the perforation openings. By these measures, the mobility can be increased or the position of a bend line to be formed can be varied. In addition to perforation lines and perforated surfaces can be provided. In this case, successive perforation cuts rotated in each case by 90 ° or also by another angle are particularly expedient in order to define preferred expansion regions. Alternatively, as an articulation aid also an impression or the like may be provided.

The movement fold is expediently formed from plastic, wherein the plastic can optionally also extend as a flat layer material on the first section and the second section. The movement fold can, for example, be injection-molded or deep-drawn from a film.

Due to the length of the pocket-shaped material supply a particularly easy and largely power-free mobility is made possible on the movement fold. If the first section and the second section are adjusted relative to one another on the movement fold, then the material supply of the movement fold rolls to a certain extent, whereby initially only the orientation of the pocket-shaped material supply and not the total length determined in a cross section changes.

According to one embodiment of the invention, the movement fold can also be formed from a stretchable, in particular an elastically extensible plastic to provide in addition to the described rolling at a height adjustment even by stretching an expanded range of motion and even with relatively large to be bridged stages To avoid tearing the material safely.

Suitable, for example, a layer of foamed plastic, which preferably has closed cells. Due to the lattice-like arrangement of the pores in the widest sense, a foam structure achieves a certain elasticity and also elasticity, whereby only comparatively low tensile forces are necessary with regard to plastic deformation due to foaming. In particular, a foamed polyolefin such as polyethylene or polypropylene may be provided. The density may be, for example, between 0.3 and 0.8 g / cm ³ .

Additionally or alternatively, however, the plastic may also have elastic properties, with thermoplastic elastomers being particularly preferably used. Suitable are, for example, olefin-based (TPO) -based thermoplastic elastomers, styrene-based thermoplastic elastomers (TPS), polyurethane-based thermoplastic elastomers (TPU), and crosslinked rubber (TPV) -based thermoplastic elastomers. Furthermore, mixtures of the polymers mentioned are also suitable. Corresponding materials are described, for example, in the "Saechtling Kunststoff-Taschenbuch", 31st Edition, 2013.

In the use of thermoplastic material and in particular thermoplastic elastomer also results in the advantage that the movement fold easily - as described above - can be formed by injection molding or deep drawing. For example, it can be provided that a suitable, initially flat film is deformed under the action of pressure and temperature with a correspondingly shaped tool to locally form the movement fold with the pocket-shaped material supply. In this case, a deformation by vacuum is included. In an injection molding, it is also possible to form only the movement fold. For example, the first and second portions may be formed of a conventional sheet material with an opening, with the motion fold then being molded. If several sections of the sheet material are provided, additional expansion zones may alternatively be created.

It is within the scope of the invention to first deep draw such a film and then to occupy with the cover material. Alternatively, it is also possible to form a laminate of the film and the covering material, in which case the area to be formed during deep-drawing is then recessed from the covering material to form the movement fold.

The first section and the second section may be substantially up to a displacement and inclination by the movement fold be arranged parallel to each other. Such an arrangement is useful, for example, when the first section is to be connected in a horizontal plane with a sanitary object. In a parallel orientation, the first section and the second section can lie in a plane as required or connect to each other via a step, for example, to compensate for a given height offset can.

The sanitary object may be, for example, a sanitary tub or a tub support system for a sanitary tub. A horizontal attachment of the first section to a sanitary tub can in particular take place when the sanitary tub expires flat at its edge without an angled or lower edge.

Alternatively, the first portion and the second portion may be disposed substantially perpendicular to one another except for a displacement and an inclination by the movement fold. Such a structure of the sealing element is useful, for example, when the first section is to be fastened to a vertical connection surface of a sanitary tub or a tub support system. The vertical connection surface can be formed for example by a lateral fold of a shower tray or bathtub, which is common in conventional designs.

The invention is finally also a sanitary installation with a sanitary object and with a sanitary sealing element, wherein the sealing element described above is sealingly attached to the first portion at a corner of the sanitary object and with the second portion to a wall and / or bottom surface of a building.

The connection to the sanitary object and the wall and / or bottom surface can be done in the usual way with adhesive. In this case, the adhesive can either be applied during assembly or already kept ready on the sanitary sealing element. The adhesive can be provided for example as a coating, adhesive bead, Klebstoffnstreifen or double-sided adhesive tape. Conveniently, in the sanitary sealing element, the adhesive is first covered with a release paper or the like, wherein such a release paper is removed only during assembly.

The 1a shows a sanitary sealing element according to the invention with a first flat section 1 and a second area section 2 , which are each L-shaped and adjacent to each other. The sanitary sealing element is intended to seal a sanitary object to an adjacent wall and / or floor surface. Corresponding is a shower area 3 on the first section 1 indicated. The shower area 3 may be formed for example of steel enamel and not shown by adhesive with the first section 1 be glued.

The second section 2 is then provided to allow a secure seal against an adjacent floor surface, wherein the corresponding area can be subsequently flowed out. To be on the perimeter of the shower area 3 overall to achieve a self-contained seal, the sanitary sealing element is combined with not shown further sanitary sealing elements or conventional sealing tapes, these additional sealing tapes or sanitary sealing elements are glued usually with an overlap.

In the 1a can be seen that to bridge a height difference between the first section 1 and the second section 2 a step 4 is provided. The stage 4 may extend to the entire sanitary sealing element or only part. In particular, the stage 4 also leak to the edges of the sanitary sealing element. Just at the corner of the shower area 3 and therefore also the corners of the L-shaped sections 1 . 2 allow for the occurrence of deviations adjustment and tensile forces Avoid, there is between the sections 1 , 2 through a bag-shaped material supply 5 one by ends 6 spatially limited movement fold 7 educated.

Through the movement fold 7 there can be the second section 2 opposite the first section 1 be adjusted in the vertical direction over a relatively large height h. The 1a shows an example of the second section 2 in the area of the movement fold in a lowered state. In the same way, the second section 2 there also be raised by the same height h.

The 1b shows the sanitary sealing element according to the 1 in a top view.

The 1c shows a section along the line AA of Fig. 1b, with the details of the through the material supply 5 formed motor fold 7 become clear. The movement fold 7 is formed of a stretchable plastic, which is preferably foamed and / or elastic. About in the 1c shown height h, the first section 1 and the second section 2 largely free of forces are shifted against each other, with only the supply of material 5 shifted along the vertical direction by a rolling motion.

Starting from a middle position of the first section 1 can the second section 2 be shifted for example by a height h of 5 to 50 mm. Even if larger height differences are to be compensated for, this can be due to the material supply 5 formed motor fold 7 if necessary, then stretch, in particular stretch elastically.

From a comparative consideration of Fig. 1a and the 1c It can also be seen that the length of the pocket-shaped material supply 5 (which in the 1c approximately the height h) from a central region of the movement fold 7 towards the ends 6 continuously and evenly on the step 4 expires.

In the embodiment of 1a to 1c has the movement fold 7 according to the sections 1 . 2 an L-shaped course, wherein the two legs of the movement fold 7 are connected by a radius to a uniform unwinding of the stock of material 5 to enable.

Basically come for the movement fold 7 also other forms into consideration. In the context of the invention, the movement fold can also be straight, arcuate or branched, for example T-branched.

The sanitary sealing element is on the first section 1 and at the second section 2 provided on both sides with nonwoven fabric as a cover material, with only the area of the movement fold 7 is recessed from the cover material.

The 2a to 2c show an alternative embodiment of the sealing element. Going out from a comparable framework are at the second section 2 starting from the bend of the movement fold 7 expansion zones 8th provided on which the cover material is recessed. The entire sanitary sealing element can, for example, have a carrier foil, which then adjoins the movement fold 7 as well as at the expansion zones 8th is not covered with nonwoven fabric or another textile as cover material.

The uncovered areas can then be easily deformed under a force and cause a balance. If the carrier film is formed from an elastic polymer, certain restoring forces are produced even without wrinkling.

The predetermined movement fold 7 is different from the expansion zones 8th among other things, that a stock of materials 5 is provided, which may be formed for example in the film by deep drawing. Due to the supply of material, a particularly large adjustment range is provided, in which case optionally a plastic and / or elastic deformation of the material supply may still follow the rolling movement of the material supply 5 can connect.

In the 2a and 2 B are also perforations 9 indicated. At the perforations 9 can be sections of the second sections 2 be folded up to connect the sanitary sealing element there then also to a wall section.

The embodiment according to the 2a to 2c This also differs from the embodiment according to FIGS. 1a to 1c, that no stage 4 between the first section 1 and the second section 2 is available.

Based on the embodiment according to the 2a show the 3 a further modification in which the previously described strain zones 8th are modified so that the cover material made of nonwoven fabric is not completely interrupted, but also at the expansion zones 8th still in the form of bars 10 remains to at least a slightly increased strength at the expansion zones 8th to achieve. Through the bars 10 becomes excessive and uncontrolled deformation at the expansion zones 8th prevents, but at the same time a sufficient mobility is provided.

In the embodiments according to the 1a to 3 are the first section 1 and the second section 2 L-shaped designed, in which case in the usual arrangement of a shower surface 3 the corner of the shower area 3 from the angled movement fold 7 is bounded.

To illustrate that other embodiments are possible within the scope of the invention, the show 4a and 4b an embodiment in which the shower area 3 in the mounted state only to one leg of the angled movement fold 7 borders. The shower area is to a subarea 1a of the first section 1 hung up while a second subarea 1b for connection to a wall surface when mounted along a perforation 9 can be folded up.

According to the embodiments described so far, the sanitary sealing element is - except for the movement fold 7 and the optionally provided stage 4 - Designed essentially flat. As a variant is against this background in the 5a shown that the first section 1 also opposite the second section 2 can be angled, for example, to the vertical edge portion of a conventional shower tray 11 to be connected.

The 5b shows at a section along the line DD of 5a the attachment of the first section 1 on the shower tray 11 , wherein in a middle orientation of the second section 2 the stock of materials 5 the movement fold 7 a bag forms.
