Definitions
- the present invention relates to a container, which in a wall, for. B. a bathroom wall, to be installed sealed and has a seal provided for this purpose. It also refers to a corresponding use of this seal.
- the container is generally meant in the context of this presentation and can, for. B. a container for receiving a concealed cistern of a toilet or other water dispenser, z. B. a purge valve, be.
- the container can form a leakage protection for the water dispenser.
- WCs have a water rinse and the most common solution involves a cistern for storing a sufficient volume of rinse water.
- Modern cisterns usually consist essentially of an injection molded or blow molded plastic tank and in the past, ceramic cisterns were in use. Regardless of the choice of material cistern always has a certain residual risk of leakage. For example. For example, a small damage to the cistern may occur on the construction site or during the assembly process and remain undetected, which would result in concealed water leakage, especially when flush-mounted cisterns are no longer visible after installation in a room wall.
- the container may instead of receiving a water dispenser but also z. B. in the manner of a piece of furniture for storage of various user-side on and clear objects, z. B. in a shower area of a bathroom. It may have to trays, such as shelves, to store, for example, soap bars, shampoo bottles, towels or the like. Even such containers for sealed wall installation are known per se.
- the container may also be part of a water outlet, in particular in a bathroom, wall drains and floor drains being considered.
- wall also applies to a floor or a ceiling, with a vertical wall (in contrast to the floor and to the ceiling) being preferred.
- a container for receiving the draining water which is also installed in a manner sealed to the wall.
- the invention has the object of developing such a container with respect to the sealing provided for the seal.
- a container for sealed installation in a wall which container has an accessible after installation in the wall opening and a surrounding the opening flexible seal, which seal has a first surface portion, which angled in the installed state to the wall and is tightly secured to a container wall part, which is installed in the Condition to the wall is angled, and has a second surface portion which is tightly connected to the first surface portion and is adapted to extend in the installed state in the wall of the container surface parallel to the wall and around the opening close to the Abut the wall, wherein the seal consists of two composite, firmly connected parts, of which a first part in the first surface portion and a second part in the second surface portion is present, and by a corresponding use of such a seal and finally by a corresponding manufacturing method for Production of the container.
- a seal is provided which surrounds the opening of the container and establishes a seal between the container and the wall. This should on the one hand remain accessible to the opening after installation, on the other hand no water in particular can penetrate into an outside of the container or the opening area and thus uncontrollably in the wall.
- This of course, particularly, but not exclusively, relates to stem walls in bathrooms or drywall, but may be e.g. B. also protect wooden walls in wooden houses or other walls.
- the seal is designed for this purpose with two surface portions, of which a first is fastened tightly against a container wall part and a second is provided for a sealing engagement with the wall.
- the container wall part extends at an angle to the wall, preferably approximately perpendicular, and may in particular be sidewalls, bottom walls or ceiling walls of the container (in contrast, for example, to the rear wall).
- the two surface portions of the seal are also angled to each other, in particular approximately perpendicular to each other, so that the first surface portion is angled to the wall and so that it can be attached to the container wall section in a particularly favorable manner.
- the second surface portion in turn, at least in the final assembled state, approximately parallel to the wall and is thus suitable for the sealing system.
- the seal, and in particular the second surface portion may have a different orientation prior to final installation, for. B. be hammered in the opening of the container inwards.
- the first surface portion is preferably already tightly attached to the container wall part in the unassembled state and prior to installation of the container.
- the seal is according to the invention but a total of two parts (or multiple parts), wherein a first sealing part is present in the first surface portion and a second sealing member in the second surface portion. This does not exclude that the first sealing part protrudes into the second surface portion and / or vice versa. Preferably, however, the first sealing part is limited to the first surface portion.
- the two sealing parts are firmly and tightly connected.
- the second surface section in turn can then z. B. outside are applied sealingly on the planking, z. B. are glued, and then in turn be covered by a wall covering, z. B. be covered with tiles.
- the two sealing parts can be made of different materials including different thicknesses and optimized for their different tasks.
- the second sealing part may be somewhat stiffer and the first sealing part somewhat more flexible. Then, when the first sealing member over the distance to be bridged in some applications in a direction perpendicular to the wall to the second surface portion, ie to rest against the wall, excess, it can be pushed together easier due to its greater flexibility (or softness) and thus the actual lower distance to be bridged will be adjusted.
- slightly stiffer second seal part can be applied well and tends to be of great importance. a. when mounted on a vertical wall, less likely to collapse.
- the material of the first and the second sealing part may differ in terms of elastic properties.
- a ("stretch") material which reacts elastically in at least one direction may be preferred because, according to experience, it can be applied easily and without bubbles in a sealing manner, for B. when sticking.
- this property does not have to be important in the first sealing part.
- the just mentioned "softness” is in terms of collapsing and collapsing a typical requirement of the first and not the second sealing part.
- a preferred flexible sealing material has, for example, clearly direction-dependent elastic properties (thus being "anisotropic"). It happens that the material in the direction of greater elasticity or even in the only elastic direction with respect to the pushing or folding "softer" is.
- z. B. an opening is sealed circumferentially would (for simplicity of a rectangle starting), for example, on certain side edges this "soft" direction in the desired direction and not on other side edges, if not pieced but is made in one piece.
- a non-inventive in this sense namely one-piece seal could be generated from a lying in the plane of the second surface portion material by deep drawing and cutting, wherein the deep-drawn portion corresponds to the first surface portion.
- the first sealing member with the desired orientation can be produced from the material and the second sealing part thereof can be produced independently. Both parts are then connected together.
- the first sealing portion for the first surface portion may then be simply cut from the sheet material and, for example, joined together at a position to produce a closed circumferential shape.
- the desired orientation along the entire first sealing part have the preferred orientation.
- the invention thus achieves improved flexibility in adapting to specific requirements, in particular in terms of elastic properties or mechanical properties (with respect to collapsing or folding) of the material used.
- the seal runs naturally closed around the opening including all possible corners, because usually a seal is desired or required.
- the second sealing part considered in itself is one-piece in so far as it has been punched or cut from a material web and contains no joints where it is connected to itself.
- the opening is substantially rectangular, as z. B. is at a leakage protection for a cistern the rule.
- the shape of the seal is preferably adapted to this.
- the first and the second sealing part can be connected to one another in the first or in the second area section, wherein a connection in the first area section is preferred.
- the two sealing parts can be glued or welded together; this also applies to the aforementioned production of a closed circumferential shape of the first sealing part. Accordingly, if the second sealing part projects slightly into the first area section for this connection point, this is preferably limited to a portion of the first area section and does not extend significantly beyond the connection to the first sealing part. Conversely, in this embodiment, the first sealing part is preferably limited to the first surface portion and preferably does not extend significantly beyond the mentioned compound.
- the compounds mentioned, in particular those between the first and the second sealing part, preferably take place flatly, the materials thus being present (at least) in two layers. If, for example, they are welded together, their separate identity naturally dissolves somewhat in this double-layeredness.
- the double-layered means so strictly speaking initially only one phase during production and in the final state at least one increased material thickness.
- this region has an increased rigidity in comparison to the remaining regions of the seal. Since it is preferably limited to only one (with respect to the wall preferably outer) portion of the first surface portion, so that the pushing together and folding of the first sealing member preferably inwardly thereof (relative to the wall) and also the mounting of the seal on the container wall and , as far as they over this outwardly (relative to the wall), even when installed in the wall, additionally supported.
- a preferred material for the gasket is a flexible film having a fiber coating on at least one side, preferably on both sides.
- the fiber layer facilitates adhesion by improving the adhesion.
- it may be a pad of polypropylene nonwoven or other nonwoven.
- the film itself ie in the case of the two-sided fiber covering the "core” is preferably an elastomer, resulting in the already mentioned stretch properties.
- the anisotropy of the elastic properties can also be caused by the fiber coating, namely z. B. in one direction, the hindering and less obstructive fibers in a direction perpendicular thereto.
- the film has thermoplastic properties.
- a thermoplastic elastomeric film is preferred.
- a further embodiment has at least one fold in the first surface portion and there preferably in the first sealing part, which is already pre-stamped during installation, for. B. is ironed.
- This at least one fold facilitates pushing together in a direction perpendicular to the wall, if the seal in this regard has excess, and also avoids excessive influence the second surface portion by uncontrolled wrinkling.
- connection between the first and the second sealing part is, as already mentioned, preferably glued or welded, in particular ultrasonically welded.
- both options are also suitable for the connection between the seal, in particular the first sealing part, and the wall of the container.
- this wall is preferably rather dimensionally stable and the connection is therefore preferably glued.
- the first sealing part may be adhesively bonded to the container wall from the outside, as the exemplary embodiment shows. The adhesive can simultaneously ensure the seal and is present over the entire length of the seal.
- Fig. 1 shows a substantially box-like container 1, namely a leakage protection cover for a concealed cistern, the open front in Fig. 1 pointing forward to the right.
- This box-like container 1 is formed from a dimensionally stable solid plastic and tightly connected to a fully circumferential opening in the front flexible seal, namely a film seal 2 made of flexible plastic material.
- Fig. 1 indicates suggestively that connects to the box-like container 1 on its underside another and closely associated leakage protection enclosure, which is provided for a flushing pipe to the male concealed cistern.
- This leakage protection cover bears the reference numeral 3 and terminates in the same front plane as the film seal 2 with a further annular film seal 4th
- substantially horizontally extending rails 5 are provided, one of which is to be seen from the outside and one from inside and serve for later insertion of the cistern.
- Fig. 1 shows the leakage protection for a better understanding of the following figures, in a state that only starting Fig. 5 is present, ie with folded to the sides of film seals 2 and 4.
- the delivery state is based on Fig. 3 and 4 explained.
- Fig. 2 shows the leakage protection Fig. 1 with a built-in concealed cistern 6 and a mounting frame 7 for mounting the cistern in and a toilet in front of a wall.
- the container 1 is provided between the cistern 6 and the mounting frame 7. Further penetrates the downwardly facing end of the leakage protection cover 3 of the flushing pipe a transverse support of the mounting frame 7, so that the film seal 4 is located in front of this carrier. Also, this condition corresponds to the following description only the Fig. 5 and not the delivery condition.
- Fig. 3 shows the mounting frame 7 with the leakage protection Fig. 1 mounted between vertical uprights 8 for a lightweight wall.
- This assembly is conventional with respect to the conventional mounting frame 7.
- the assembled unit additionally has a building protection plate 9 on the front, which in the Fig. 1 and 2 recognizable opening of the container 1 largely covers.
- the film seals 2 and 4 are taken (and the film seal 4 is in turn also protected by an essay).
- Bauschplatte 9 the delivery condition; in Fig. 3
- the delivered and preassembled ensemble of mounting frame 7, container 1 and concealed cistern 6 is mounted with Bauschutzplatte 9.
- the lightweight wall 10 can then be mounted on the vertical supports 8, such as Fig. 4 shows, with the protective wall 9 serves as a reference line or stop. After their removal, the film seals 2 and 4 are then handled as Fig. 5 shows, and can be glued, for example, on the lightweight wall 10.
- Fig. 6 shows next to this situation on the lightweight wall 10 leaning a matching to the opening cover plate 11, are mounted on the fitting parts 12 not shown here.
- Fig. 7 shows how after mounting the cover plate 11 in the opening, the lightweight wall 10 has been tiled including the now flush with it cover plate 11.
- the tile layer has the reference numeral 13. It is provided on the outer contour of the cover plate 11 in the tiles a slot, in this example, the upper slot to a tile joint fits, but not the remaining three slots. These are realized by appropriate cuts in the tiles. All slots are then grouted with silicone. The tiles 13 are also glued to the folded film seals 2 and 4.
- Fig. 8 shows that around the Spülrohrstutzen and the drain pipe of the not yet visible toilets around a soundproofing plate 14 has been applied. This is conventional apart from a detail in itself. This detail is one of the Spülrohrstutzen from obliquely downwards (in Fig. 8 towards the bottom left) running gutter or depression 15.
- Fig. 9 the installation is then completed by a WC 16 and a conventional actuator plate 17 are mounted. If, in this situation, leaking should occur on the cistern 6 or its flushing pipe, the box-like container 1 or the corresponding envelope 3 leads the corresponding leakage water in the case shown here, at least through the enclosure 3 of the flushing pipe to the flushing pipe outlet and allows it to drain through the channel 15. The water is thus visible next to the toilet 16 on the floor as a puddle.
- the user recognizes the presence of a leak.
- the user can then initiate a repair.
- the craftsman cuts open the silicone joint, which separates the tiles from the cover plate 11 from the rest, and applies for example a suction cup on the tiles on the cover plate 11 at.
- the cover plate 12 can now be pulled forward due to the special design of the fitting parts, so that the cistern 6 is accessible.
- This can now be removed, including the flush pipe attached to it, by a tilting movement, which in Fig. 10 is indicated. It is in turn replaced by an intact cistern 6, whereupon the cover plate 11 is attached again, the silicone joint created again and the actuator plate 17 is mounted.
- Fig. 11 shows the film seal 2 alone in perspective view for a better understanding of their structure. It consists of two parts, namely a first part 20 and a second part 21.
- the first part is present in a rectangular all-round first surface section, which in comparison with z. B.
- Fig. 1, 2 and 5 can be seen perpendicular to the plane of the wall.
- the second part 21 lies substantially in a second surface section lying perpendicular thereto and lying in the wall plane.
- the two parts are welded together in an overlapping region 22.
- These consist of a three-layer material, namely a middle thermoplastic elastomeric film which is coated on both sides with a polypropylene non-woven.
- the fleece is transversely extensible in one direction (in the area) and almost non-directional in the other direction perpendicular thereto.
- thermoplastic cores of the two parts 20 and 21 are capable of flow relative to one another at least at their boundary surface and thus produce the welded joint.
- the overlap area 22 is located in the in Fig. 11 top and with respect to the mounting position outermost part of the first surface portion and at the same time at the edge of the first part 20 and the second part 21. It follows that the second part has received by a conventional deep drawing a collar corresponding to the collar 22, the something in protrudes the first surface section.
- Fig. 11 Further, it indicates a seam 23 in the first seal part 20.
- the first seal part 20 has been cut out of the sheet raw material just like the second seal part 21, and then bent into the rectangular shape and ultrasonically welded to the seam 23 in the manner just described.
- the film seal 2 has Fig. 11 two ironed in folds, which in Fig. 11 not shown, but off Fig. 12 result.
- Fig. 11 two ironed in folds, which in Fig. 11 not shown, but off Fig. 12 result.
- FIG. 11 There is a schematic and perspective cutout representation, front left partially cut, a corner of the film seal 2 drawn in the installed state.
- a part of the mounting frame 7, namely a cut vertical stand 8, and additionally a part of the lightweight wall 10 can be seen.
- the first part 20 is glued in a manner also shown in section with an indicated adhesive layer on the outside of a front wall portion of the container 1 with respect to the installed position and thus sealed. Accordingly, the runs in Fig. 12 recognizable adhesive layer once closed around.
- Fig. 12 further shows the overlap region 22 at the upper end of the first surface portion and the first seal member 20 and the inner end of the second seal member 21 and the second surface portion and then at right angles.
- Fig. 12 is also the double-dashed lines the cover plate 11 (see. Fig. 6 ) indicated.
- cover plate 11 Under this indicated cover plate 11 can be seen a "zigzag-line" of the first seal member, namely a formed by three folds and approximately V-shaped inwardly facing bellows. This is characterized by three pre-stamped fold lines, a top fold line 24, a middle and in Fig. 12 inwardly directed fold line 25 and a third lower fold line 26 pre-stamped.
- the first sealing member 20 of the film seal 2 settles relatively easily and neatly not only because of the pre-ironed folds 24 to 26, but also because of the mechanical reinforcement due to the double layering of the material in the overlap region 22 (and the possible thickening of the elastomer core due to welding or, in other examples, by adhesive).
- This is a kind of rigid framework.
- the nonwoven-coated elastomeric material has in this case been processed for the first sealing part 20 so that the direction of maximum extensibility is perpendicular to the wall plane, ie in Fig. 12 vertical.
- the same material was used for the second sealing member 21, wherein here, depending on the leg of the rectangular shape, the direction of extensibility in this embodiment is partly perpendicular and partly parallel to the edges of the opening, in another embodiment, but also obliquely, approximately diagonally , could be.
- the substantially unilaterally extensible material has proven to be particularly favorable for achieving a flat contact without bubbles when gluing or
- the one-sided elastic material has proven particularly useful. At the same time, such material is typical to be the softest in the direction of maximum elasticity in terms of folding or pushing together.
- Fig. 12 recognizable bellows-like intake of excess material (in Fig. 12 in the vertical direction) works best with the least interference at the corner between the two surface portions of the two-part seal, when said seal at the first seal part is perpendicular (or approximately perpendicular) to the wall plane. This would not be possible with a one-piece production of the seal with complete deep drawing of the first surface portion.
- the two-sided nonwoven covering has the advantage in the second surface section, on the one hand to facilitate adhesion to the planking of the lightweight wall 10, cf. Fig. 12 on the other hand, but also to facilitate a later over-tiling or other sticking a wall cladding, see. Fig. 7 ,
- the flexible seal 2 has a total of the advantage of being able to be taken before installation in the opening of the container and can be removed from it and transferred to the outside only during or after assembly of the container in the manner described.
- the material has an approximate surface mass density of 300 to 350 g / m 2 and is stretchable in the elastic direction to three times its unloaded dimensions, in the direction perpendicular thereto only to one and a half times, both values corresponding to the elongation at break and thus extreme conditions.
- the thickness is about 0.6 to 0.7 mm.

Description
Die vorliegende Erfindung bezieht sich auf ein Behältnis, das in eine Wand, z. B. eine Badezimmerwand, abgedichtet eingebaut werden soll und eine hierzu vorgesehene Dichtung aufweist. Sie bezieht sich ferner auf eine entsprechende Verwendung dieser Dichtung.The present invention relates to a container, which in a wall, for. B. a bathroom wall, to be installed sealed and has a seal provided for this purpose. It also refers to a corresponding use of this seal.
Das Behältnis ist im Rahmen dieser Darstellung allgemein gemeint und kann z. B. ein Behältnis zur Aufnahme eines Unterputzspülkastens eines WC oder eines anderen Wasserabgabegeräts, z. B. eines Spülventils, sein. Insbesondere kann das Behältnis dabei einen Leckageschutz für das Wasserabgabegerät bilden.The container is generally meant in the context of this presentation and can, for. B. a container for receiving a concealed cistern of a toilet or other water dispenser, z. B. a purge valve, be. In particular, the container can form a leakage protection for the water dispenser.
WCs haben nämlich definitionsgemäß eine Wasserspülung und die häufigste Lösung beinhaltet einen Spülkasten zur Bevorratung eines ausreichenden Spülwasservolumens. Moderne Spülkästen bestehen in der Regel im Wesentlichen aus einem spritzgegossenen oder blasgeformten Kunststofftank und in der Vergangenheit waren auch keramische Spülkästen gebräuchlich. Unabhängig von der Materialwahl besteht bei Spülkästen immer ein gewisses kleines Restrisiko einer Leckage. Bspw. könnte eine kleine Beschädigung des Spülkastens auf der Baustelle oder während des Montagevorgangs auftreten und unentdeckt bleiben, was insbesondere bei nach Einbau in eine Raumwand nicht mehr sichtbarem Unterputzspülkästen eine verborgene Wasserleckage zur Folge hätte.By definition, WCs have a water rinse and the most common solution involves a cistern for storing a sufficient volume of rinse water. Modern cisterns usually consist essentially of an injection molded or blow molded plastic tank and in the past, ceramic cisterns were in use. Regardless of the choice of material cistern always has a certain residual risk of leakage. For example. For example, a small damage to the cistern may occur on the construction site or during the assembly process and remain undetected, which would result in concealed water leakage, especially when flush-mounted cisterns are no longer visible after installation in a room wall.
Ähnliche Probleme stellen sich dementsprechend auch bei anderen Unterputz-Wasserabgabegeräten, z. B. Unterputzspülventilen, also Ventilen für eine Spülkasten-lose WC-Spülung, Unterputzarmaturen und Unterputzmischventilen.Accordingly, similar problems arise with other flush-mounted water dispensers, z. B. flush-mounted flush valves, so valves for a cistern-less toilet flushing, concealed fittings and flush-mounted mixing valves.
Die beschriebenen unentdeckten Leckagen sind vor allem für Holzhäuser oder Holzelemente in Häusern hochproblematisch und können zu erheblichen Schäden führen. Daher sind zusätzliche Schutzmaßnahmen je nach betroffenem Land erwünscht oder sogar vorgeschrieben.The described undetected leaks are especially problematic for wooden houses or wooden elements in houses and can lead to considerable damage. Therefore, additional protective measures are desired or even required depending on the country concerned.
In diesem Zusammenhang gibt es unterschiedliche Lösungen in Form von mehr oder weniger vom Spülkasten entfernten Hartkunststoffschalen oder - umhüllungen, die das Wasser aus einem Leck z. B. auf den Badezimmerfußboden und damit in einen sichtbaren Bereich leiten sollen. Beispielhaft wird verwiesen auf die
Das Behältnis kann statt zur Aufnahme eines Wasserabgabegeräts aber auch z. B. in der Art eines Möbels zur Aufbewahrung von verschiedenen benutzerseitig ein- und auszuräumenden Gegenständen dienen, z. B. in einem Duschbereich eines Badezimmers. Es kann dazu Tragböden, etwa Einlegeböden, aufweisen, um bspw. Seifenstücke, Shampooflaschen, Handtücher oder Ähnliches zu lagern. Auch solche Behältnisse zum abgedichteten Wandeinbau sind an sich bekannt.The container may instead of receiving a water dispenser but also z. B. in the manner of a piece of furniture for storage of various user-side on and clear objects, z. B. in a shower area of a bathroom. It may have to trays, such as shelves, to store, for example, soap bars, shampoo bottles, towels or the like. Even such containers for sealed wall installation are known per se.
Schließlich kann das Behältnis auch Teil eines Wasserablaufs sein, insbesondere in einem Badezimmer, wobei Wandabläufe und Bodenabläufe in Betracht kommen. Der Begriff der "Wand" ist im Rahmen dieser Erfindung nämlich auch auf einen Boden oder eine Decke zu beziehen, wobei eine vertikale Wand (im Gegensatz zum Boden und zur Decke) bevorzugt ist. In Wand- oder Bodenabläufen gibt es in der Regel ein Behältnis zur Aufnahme des ablaufenden Wassers, das ebenfalls in einer zur Wand abgedichteten Weise eingebaut wird.Finally, the container may also be part of a water outlet, in particular in a bathroom, wall drains and floor drains being considered. Namely, in the context of this invention, the term "wall" also applies to a floor or a ceiling, with a vertical wall (in contrast to the floor and to the ceiling) being preferred. In wall or floor drains, there is usually a container for receiving the draining water, which is also installed in a manner sealed to the wall.
Der Erfindung liegt die Aufgabe zugrunde, ein solches Behältnis hinsichtlich der für die Abdichtung vorgesehenen Dichtung weiterzubilden.The invention has the object of developing such a container with respect to the sealing provided for the seal.
Gelöst wird diese Aufgabe durch ein Behältnis zum abgedichteten Einbau in eine Wand, welches Behältnis eine nach dem Einbau in die Wand zugängliche Öffnung aufweist und eine die Öffnung umgebende flexible Dichtung aufweist, welche Dichtung einen ersten Flächenabschnitt hat, welcher im eingebauten Zustand zu der Wand gewinkelt und an einem Behälterwandteil dicht befestigt ist, der im eingebauten Zustand zu der Wand gewinkelt verläuft, und einen zweiten Flächenabschnitt hat, der dicht mit dem ersten Flächenabschnitt verbunden ist und dazu ausgelegt ist, in dem in die Wand eingebauten Zustand des Behältnisses flächig parallel zu der Wand zu verlaufen und um die Öffnung herum dicht an der Wand anzuliegen, wobei die Dichtung aus zwei zusammengesetzten, miteinander fest verbundenen Teilen besteht, von denen ein erstes Teil in dem ersten Flächenabschnitt und ein zweites Teil in dem zweiten Flächenabschnitt vorliegt, sowie durch eine entsprechende Verwendung einer solchen Dichtung und schließlich durch ein entsprechendes Herstellungsverfahren zur Herstellung des Behältnisses.This object is achieved by a container for sealed installation in a wall, which container has an accessible after installation in the wall opening and a surrounding the opening flexible seal, which seal has a first surface portion, which angled in the installed state to the wall and is tightly secured to a container wall part, which is installed in the Condition to the wall is angled, and has a second surface portion which is tightly connected to the first surface portion and is adapted to extend in the installed state in the wall of the container surface parallel to the wall and around the opening close to the Abut the wall, wherein the seal consists of two composite, firmly connected parts, of which a first part in the first surface portion and a second part in the second surface portion is present, and by a corresponding use of such a seal and finally by a corresponding manufacturing method for Production of the container.
Bevorzugte Ausgestaltungen sind Gegenstand der abhängigen Ansprüche und werden im Folgenden neben der Erfindung in ihrem allgemeinen Sinn näher erläutert. Dies bezieht sich auf das Behältnis und die Verwendung gleichermaßen, ohne dass zwischen diesen beiden im Einzelnen explizit unterschieden wird.Preferred embodiments are the subject of the dependent claims and are explained in detail below in addition to the invention in its general sense. This relates to the container and the use alike, without explicitly distinguishing between the two.
Erfindungsgemäß ist eine Dichtung vorgesehen, die die Öffnung des Behältnisses umgibt und eine Abdichtung zwischen dem Behältnis und der Wand herstellt. Damit soll einerseits die Öffnung nach dem Einbau zugänglich bleiben, andererseits insbesondere kein Wasser in einen außerhalb des Behältnisses bzw. der Öffnung liegenden Bereich und damit unkontrolliert in die Wand eindringen können. Dies bezieht sich natürlich besonders, aber nicht ausschließlich, auf Vorbauwände in Badezimmern oder Trockenbauwände, kann aber z. B. auch Holzwände in Holzhäusern oder andere Wände schützen.According to the invention, a seal is provided which surrounds the opening of the container and establishes a seal between the container and the wall. This should on the one hand remain accessible to the opening after installation, on the other hand no water in particular can penetrate into an outside of the container or the opening area and thus uncontrollably in the wall. This, of course, particularly, but not exclusively, relates to stem walls in bathrooms or drywall, but may be e.g. B. also protect wooden walls in wooden houses or other walls.
Die Dichtung ist dazu mit zwei Flächenabschnitten ausgestaltet, von denen ein erster dicht an einem Behälterwandteil befestigt ist und ein zweiter für eine dichtende Anlage an der Wand vorgesehen ist. Der Behälterwandteil verläuft dabei gewinkelt zur Wand, vorzugsweise ungefähr senkrecht, und es kann sich insbesondere um Seitenwände, Bodenwände oder Deckenwände des Behälters handeln (im Unterschied z. B. zur Rückwand). Die beiden Flächenabschnitte der Dichtung sind dabei ebenfalls zueinander gewinkelt, insbesondere ungefähr senkrecht zueinander, sodass der erste Flächenabschnitt gewinkelt zur Wand verläuft und damit besonders günstig dicht an dem Behälterwandabschnitt angebracht werden oder sein kann. Der zweite Flächenabschnitt wiederum verläuft, jedenfalls im endgültig montierten Zustand, in etwa parallel zur Wand und eignet sich damit für die dichtende Anlage.The seal is designed for this purpose with two surface portions, of which a first is fastened tightly against a container wall part and a second is provided for a sealing engagement with the wall. The container wall part extends at an angle to the wall, preferably approximately perpendicular, and may in particular be sidewalls, bottom walls or ceiling walls of the container (in contrast, for example, to the rear wall). The two surface portions of the seal are also angled to each other, in particular approximately perpendicular to each other, so that the first surface portion is angled to the wall and so that it can be attached to the container wall section in a particularly favorable manner. The second surface portion in turn, at least in the final assembled state, approximately parallel to the wall and is thus suitable for the sealing system.
Wenn hier von "ungefähr senkrecht" oder "senkrecht" die Rede ist, kann dies vorzugsweise einen Winkel von 70 ° bis 110 °, besonders bevorzugter Weise 75 ° bis 105 ° bzw. 80 ° bis 100 ° oder 85 ° bis 95 ° bedeuten, wobei die Wahl der Grenzen in den verschiedenen Sinnzusammenhängen natürlich unabhängig voneinander erfolgt.When this is referred to as "approximately vertical" or "perpendicular", this may preferably be an angle of 70 ° to 110 °, particularly preferably 75 ° to 105 ° or 80 ° to 100 ° or 85 ° to 95 °, Of course, the choice of boundaries in the different contexts is independent of each other.
Allerdings kann die Dichtung und kann insbesondere der zweite Flächenabschnitt vor dem endgültigen Einbau eine andere Orientierung haben, z. B. in die Öffnung des Behälters nach innen eingeschlagen sein. Der erste Flächenabschnitt wiederum ist im noch nicht montierten Zustand und vor Einbau des Behälters vorzugsweise bereits an dem Behälterwandteil dicht angebracht.However, the seal, and in particular the second surface portion may have a different orientation prior to final installation, for. B. be hammered in the opening of the container inwards. The first surface portion, in turn, is preferably already tightly attached to the container wall part in the unassembled state and prior to installation of the container.
Für die Herstellung einer solchen Dichtung bietet sich konventioneller Weise ein flächiges Folienmaterial an, aus dem die gewünschte winklige Struktur (bei der der erste zum zweiten Flächenabschnitt gewinkelt ist) z. B. durch Tiefziehen oder anderes Umformen in einem Stück erzeugt wird.For the production of such a seal conventionally offers a sheet-like sheet material, from which the desired angular structure (in which the first is angled to the second surface portion) z. B. is produced by deep drawing or other forming in one piece.
Die Dichtung ist erfindungsgemäß aber insgesamt zweiteilig (oder mehrteilig), wobei ein erster Dichtungsteil in dem ersten Flächenabschnitt vorliegt und ein zweiter Dichtungsteil in dem zweiten Flächenabschnitt. Das schließt nicht aus, dass der erste Dichtungsteil in den zweiten Flächenabschnitt hineinragt und/oder umgekehrt. Vorzugsweise allerdings beschränkt sich der erste Dichtungsteil auf den ersten Flächenabschnitt. Die beiden Dichtungsteile sind fest und dicht miteinander verbunden.The seal is according to the invention but a total of two parts (or multiple parts), wherein a first sealing part is present in the first surface portion and a second sealing member in the second surface portion. This does not exclude that the first sealing part protrudes into the second surface portion and / or vice versa. Preferably, however, the first sealing part is limited to the first surface portion. The two sealing parts are firmly and tightly connected.
Beim Einsatz der Dichtungen und des Behälters können dabei verschiedene Situationen auftreten, die zu unterschiedlichen Maßen hinsichtlich der Richtung senkrecht zur Wand führen. Z. B. können beim Einbau unterschiedlich starke Beplankungen der Wand Verwendung finden. Es ist dann von großem Vorteil, mit dem ersten Flächenabschnitt der Dichtung entsprechend überbrücken zu können und infolge eines Übermaßes und einer gewissen Flexibilität auf unterschiedliche Maße Rücksicht nehmen zu können. Der zweite Flächenabschnitt wiederum kann dann z. B. außen auf die Beplankung dichtend aufgebracht werden, z. B. aufgeklebt werden, und danach seinerseits wiederum von einer Wandverkleidung überdeckt werden, z. B. mit Fliesen beklebt werden.When using the seals and the container, various situations can occur, the direction in different dimensions lead perpendicular to the wall. For example, different thicknesses of the wall can be used during installation. It is then of great advantage to be able to bridge accordingly with the first surface portion of the seal and due to an excess and a certain flexibility to be able to take account of different dimensions. The second surface section in turn can then z. B. outside are applied sealingly on the planking, z. B. are glued, and then in turn be covered by a wall covering, z. B. be covered with tiles.
Die zweiteilige Ausführung kann dabei in verschiedener Weise vorteilhaft genutzt werden. So können die beiden Dichtungsteile aus verschiedenen einschließlich verschieden dicken Materialien bestehen und für ihre unterschiedlichen Aufgaben optimiert sein. Insbesondere kann dabei der zweite Dichtungsteil etwas steifer sein und der erste Dichtungsteil etwas flexibler. Wenn dann der erste Dichtungsteil gegenüber der in manchen Anwendungsfällen zu überbrückenden Distanz in einer Richtung senkrecht zur Wand bis zu dem zweiten Flächenabschnitt, also zur Anlage an der Wand, Übermaß aufweist, kann er infolge seiner größeren Flexibilität (oder Weichheit) leichter zusammengeschoben und damit an die tatsächlich geringere zu überbrückende Distanz angepasst werden.The two-part design can be used advantageously in various ways. Thus, the two sealing parts can be made of different materials including different thicknesses and optimized for their different tasks. In particular, the second sealing part may be somewhat stiffer and the first sealing part somewhat more flexible. Then, when the first sealing member over the distance to be bridged in some applications in a direction perpendicular to the wall to the second surface portion, ie to rest against the wall, excess, it can be pushed together easier due to its greater flexibility (or softness) and thus the actual lower distance to be bridged will be adjusted.
Andererseits kann der etwas steifere zweite Dichtungsteil gut angelegt werden und neigt, v. a. bei Montage an einer vertikalen Wand, weniger zu einem Kollabieren.On the other hand, the slightly stiffer second seal part can be applied well and tends to be of great importance. a. when mounted on a vertical wall, less likely to collapse.
Zusätzlich oder alternativ können sich das Material des ersten und das des zweiten Dichtungsteils unterscheiden hinsichtlich elastischer Eigenschaften. Es kann etwa im zweiten Dichtungsteil ein zumindest in einer Richtung elastisch reagierendes ("Stretch"-) Material bevorzugt sein, weil sich dieses erfahrungsgemäß leicht und blasenfrei dichtend anlegen lässt, z. B. beim Aufkleben. Diese Eigenschaft muss aber beim ersten Dichtungsteil nicht von Bedeutung sein. Umgekehrt ist die gerade erwähnte "Weichheit" hinsichtlich eines Zusammenschiebens und Zusammenfaltens eine typische Anforderung des ersten und nicht des zweiten Dichtungsteils.Additionally or alternatively, the material of the first and the second sealing part may differ in terms of elastic properties. For example, in the second sealing part, a ("stretch") material which reacts elastically in at least one direction may be preferred because, according to experience, it can be applied easily and without bubbles in a sealing manner, for B. when sticking. However, this property does not have to be important in the first sealing part. Conversely, the just mentioned "softness" is in terms of collapsing and collapsing a typical requirement of the first and not the second sealing part.
Auch wenn, was an sich bevorzugt ist, für beide Dichtungsteile das gleiche Material Verwendung findet, kann die Erfindung ähnliche Vorteile bieten, z. B. wenn dieses Material richtungsabhängige Eigenschaften hat. Ein bevorzugtes flexibles Dichtungsmaterial weist bspw. deutlich richtungsabhängige elastische Eigenschaften auf (ist also "anisotrop"). Dabei kommt es vor, dass das Material in der Richtung der größeren Elastizität oder überhaupt in der einzig elastischen Richtung im Hinblick auf das Zusammenschieben oder -falten "weicher" ist.Even if, which is preferred per se, the same material is used for both sealing parts, the invention can offer similar advantages, for. B. if this material has directional properties. A preferred flexible sealing material has, for example, clearly direction-dependent elastic properties (thus being "anisotropic"). It happens that the material in the direction of greater elasticity or even in the only elastic direction with respect to the pushing or folding "softer" is.
Wenn z. B. eine Öffnung umlaufend abgedichtet wird, dann würde (zur Vereinfachung von einem Rechteck ausgehend) bspw. an bestimmten Seitenkanten diese "weiche" Richtung in der gewünschten Richtung liegen und an anderen Seitenkanten nicht, wenn nicht gestückelt sondern einstückig gearbeitet wird. Z. B. könnte eine in diesem Sinn nicht erfindungsgemäße, nämlich einteilige Dichtung aus einem in der Ebene des zweiten Flächenabschnitts liegenden Material durch Tiefziehen und Zuschneiden erzeugt werden, wobei der tiefgezogene Bereich dem ersten Flächenabschnitt entspricht. Wenn nun erfindungsgemäß eine Zweiteiligkeit gewählt wird, kann der erste Dichtungsteil mit der gewünschten Ausrichtung aus dem Material erzeugt werden und der zweite Dichtungsteil davon unabhängig hergestellt werden. Beide Teile werden dann miteinander verbunden.If z. B. an opening is sealed circumferentially, then would (for simplicity of a rectangle starting), for example, on certain side edges this "soft" direction in the desired direction and not on other side edges, if not pieced but is made in one piece. For example, a non-inventive in this sense, namely one-piece seal could be generated from a lying in the plane of the second surface portion material by deep drawing and cutting, wherein the deep-drawn portion corresponds to the first surface portion. Now, if a bipartite is chosen according to the invention, the first sealing member with the desired orientation can be produced from the material and the second sealing part thereof can be produced independently. Both parts are then connected together.
Der erste Dichtungsteil für den ersten Flächenabschnitt kann dann einfach aus dem Bahnmaterial geschnitten und bspw. an einer Stelle zur Erzeugung einer geschlossenen umlaufenden Form zusammengefügt werden. Dabei kann die gewünschte Ausrichtung entlang dem gesamten ersten Dichtungsteil die Vorzugsorientierung haben.The first sealing portion for the first surface portion may then be simply cut from the sheet material and, for example, joined together at a position to produce a closed circumferential shape. In this case, the desired orientation along the entire first sealing part have the preferred orientation.
Durch eine Herstellung aus zwei zunächst getrennten und dann zusammengesetzten und miteinander fest und dicht verbundenen Teilen erreicht die Erfindung also eine verbesserte Flexibilität in der Anpassung an bestimmte Anforderungen, insbesondere hinsichtlich der elastischen Eigenschaften oder mechanischen Eigenschaften (hinsichtlich Zusammenschieben oder -falten) des verwendeten Materials.By manufacturing from two initially separate and then assembled and tightly and tightly connected parts, the invention thus achieves improved flexibility in adapting to specific requirements, in particular in terms of elastic properties or mechanical properties (with respect to collapsing or folding) of the material used.
Vorzugsweise läuft die Dichtung natürlich geschlossen um die Öffnung herum einschließlich aller eventuellen Ecken, denn im Regelfall ist eine Abdichtung rundum gewünscht oder erforderlich. Vorzugsweise ist das zweite Dichtungsteil für sich betrachtet insoweit einteilig, als es aus einer Materialbahn ausgestanzt oder - geschnitten wurde und keine Verbindungsstellen enthält, an denen es mit sich selbst verbunden ist.Preferably, the seal runs naturally closed around the opening including all possible corners, because usually a seal is desired or required. Preferably, the second sealing part considered in itself is one-piece in so far as it has been punched or cut from a material web and contains no joints where it is connected to itself.
Vorzugsweise ist die Öffnung im Wesentlichen rechteckig, wie dies z. B. bei einem Leckageschutz für einen Spülkasten der Regelfall ist. Daran ist die Form der Dichtung vorzugsweise angepasst.Preferably, the opening is substantially rectangular, as z. B. is at a leakage protection for a cistern the rule. The shape of the seal is preferably adapted to this.
Der erste und der zweite Dichtungsteil können im ersten oder im zweiten Flächenabschnitt miteinander verbunden werden, wobei eine Verbindung im ersten Flächenabschnitt bevorzugt ist. Bspw. können die beiden Dichtungsteile miteinander verklebt oder verschweißt werden; das gilt auch für die zuvor erwähnte Herstellung einer geschlossenen umlaufenden Form des ersten Dichtungsteils. Wenn dementsprechend der zweite Dichtungsteil zu dieser Verbindungsstelle etwas in den ersten Flächenabschnitt hineinragt, so begrenzt sich das vorzugsweise auf einen Anteil des ersten Flächenabschnitts und geht nicht wesentlich über die Verbindung zum ersten Dichtungsteil hinaus. Umgekehrt ist bei dieser Ausgestaltung der erste Dichtungsteil vorzugsweise auf den ersten Flächenabschnitt begrenzt und geht vorzugsweise nicht wesentlich über die erwähnte Verbindung hinaus.The first and the second sealing part can be connected to one another in the first or in the second area section, wherein a connection in the first area section is preferred. For example. the two sealing parts can be glued or welded together; this also applies to the aforementioned production of a closed circumferential shape of the first sealing part. Accordingly, if the second sealing part projects slightly into the first area section for this connection point, this is preferably limited to a portion of the first area section and does not extend significantly beyond the connection to the first sealing part. Conversely, in this embodiment, the first sealing part is preferably limited to the first surface portion and preferably does not extend significantly beyond the mentioned compound.
Die erwähnten Verbindungen, insbesondere die zwischen dem ersten und dem zweiten Dichtungsteil, erfolgen vorzugsweise flächig, wobei die Materialien damit (mindestens) doppellagig vorliegen. Wenn sie beispielsweise miteinander verschweißt werden, löst sich natürlich in dieser Doppellagigkeit ihre voneinander getrennte Identität etwas auf. Die Doppellagigkeit meint also streng genommen zunächst nur eine Phase während der Herstellung und im endgültigen Zustand mindestens eine erhöhte Materialstärke.The compounds mentioned, in particular those between the first and the second sealing part, preferably take place flatly, the materials thus being present (at least) in two layers. If, for example, they are welded together, their separate identity naturally dissolves somewhat in this double-layeredness. The double-layered means so strictly speaking initially only one phase during production and in the final state at least one increased material thickness.
Infolge der erwähnten Doppellagigkeit oder einer anderen Form der Versteifung im Verbindungsbereich, etwa durch Klebstoff, hat dieser Bereich gegenüber den übrigen Bereichen der Dichtung eine erhöhte Steifigkeit. Da er sich vorzugsweise nur auf einen (in Bezug auf die Wand vorzugsweise äußeren) Teil des ersten Flächenabschnitts beschränkt, kann damit das Zusammenschieben und Zusammenfalten des ersten Dichtungsteils vorzugsweise einwärts davon (bezogen auf die Wand) und auch die Montage der Dichtung an der Behälterwand und, soweit sie über diese nach außen (bezogen auf die Wand) übersteht, auch beim Einbau in der Wand, zusätzlich unterstützt werden.As a result of the mentioned double-layeredness or another form of stiffening in the connection region, for example by means of adhesive, this region has an increased rigidity in comparison to the remaining regions of the seal. Since it is preferably limited to only one (with respect to the wall preferably outer) portion of the first surface portion, so that the pushing together and folding of the first sealing member preferably inwardly thereof (relative to the wall) and also the mounting of the seal on the container wall and , as far as they over this outwardly (relative to the wall), even when installed in the wall, additionally supported.
Ein bevorzugtes Material für die Dichtung ist eine flexible Folie, und zwar mit einem Faserbelag auf mindestens einer Seite, vorzugsweise auf beiden Seiten. Der Faserbelag erleichtert das Verkleben durch Haftungsverbesserung. Z. B. kann es sich um einen Belag aus Polypropylenvlies oder einem anderen Vlies handeln. Die Folie selbst, also im Fall des zweiseitigen Faserbelags der "Kern" ist vorzugsweise ein Elastomer, woraus sich die bereits erwähnten Stretcheigenschaften ergeben. Die Anisotropie der elastischen Eigenschaften kann dabei auch durch den Faserbelag bedingt sein, nämlich z. B. in einer Richtung die Dehnung behindernde und in einer dazu senkrechten Richtung weniger behindernde Fasern.A preferred material for the gasket is a flexible film having a fiber coating on at least one side, preferably on both sides. The fiber layer facilitates adhesion by improving the adhesion. For example, it may be a pad of polypropylene nonwoven or other nonwoven. The film itself, ie in the case of the two-sided fiber covering the "core" is preferably an elastomer, resulting in the already mentioned stretch properties. The anisotropy of the elastic properties can also be caused by the fiber coating, namely z. B. in one direction, the hindering and less obstructive fibers in a direction perpendicular thereto.
Für die erwähnten Schweißeigenschaften ist es günstig, wenn die Folie thermoplastische Eigenschaften hat. Insbesondere ist eine thermoplastische Elastomerfolie bevorzugt.For the mentioned welding properties, it is favorable if the film has thermoplastic properties. In particular, a thermoplastic elastomeric film is preferred.
Eine weitere Ausgestaltung weist zumindest eine Falte in dem ersten Flächenabschnitt und dort vorzugsweise in dem ersten Dichtungsteil auf, die schon beim Einbau vorgeprägt ist, z. B. gebügelt ist. Diese mindestens eine Falte erleichtert das Zusammenschieben in einer zu der Wand senkrechten Richtung, wenn die Dichtung diesbezüglich Übermaß hat, und vermeidet auch eine zu starke Beeinflussung des zweiten Flächenabschnitts durch unkontrollierte Faltenbildung. Vorzugsweise sind mindestens zwei und besonders bevorzugter Weise genau drei Falten vorgesehen. Die Funktionsweise ähnelt dann einem Balg.A further embodiment has at least one fold in the first surface portion and there preferably in the first sealing part, which is already pre-stamped during installation, for. B. is ironed. This at least one fold facilitates pushing together in a direction perpendicular to the wall, if the seal in this regard has excess, and also avoids excessive influence the second surface portion by uncontrolled wrinkling. Preferably, at least two and more preferably exactly three folds are provided. The operation then resembles a bellows.
Die Verbindung zwischen dem ersten und dem zweiten Dichtungsteil ist, wie bereits erwähnt, vorzugsweise geklebt oder geschweißt, insbesondere ultraschallgeschweißt. Beide Möglichkeiten kommen natürlich auch für die Verbindung zwischen der Dichtung, insbesondere dem ersten Dichtungsteil, und der Wand des Behältnisses in Betracht. Diese Wand ist allerdings vorzugsweise eher formstabil und die Verbindung ist daher vorzugsweise geklebt. Insbesondere kann der erste Dichtungsteil von außen an die Behälterwand angeklebt sein, wie das Ausführungsbeispiel zeigt. Dabei kann der Klebstoff gleichzeitig die Abdichtung sicherstellen und ist über die gesamte Länge der Dichtung vorhanden.The connection between the first and the second sealing part is, as already mentioned, preferably glued or welded, in particular ultrasonically welded. Of course, both options are also suitable for the connection between the seal, in particular the first sealing part, and the wall of the container. However, this wall is preferably rather dimensionally stable and the connection is therefore preferably glued. In particular, the first sealing part may be adhesively bonded to the container wall from the outside, as the exemplary embodiment shows. The adhesive can simultaneously ensure the seal and is present over the entire length of the seal.

Auch wenn das Wasser bei einer anderen Ausgestaltung ohne Spülrohrumhüllung infolge eines Spülkastenlecks nach vorne zur vorderseitigen Öffnung des Behältnisses 1 gelangen sollte, würde es letztlich ohne Probleme auf den Fußboden des Badezimmers gelangen, weil die Vorderseite der Leichtbauwand 10 üblicherweise wasserfest ausgestaltet ist.Even if the water should go in another embodiment without Spülrohrumhüllung due to a Spülkastenlecks forward to the front opening of the container 1, it would ultimately go without any problems on the floor of the bathroom, because the front of the
In jedem Fall erkennt der Benutzer das Vorliegen eines Lecks. Daraufhin kann der Benutzer eine Reparatur veranlassen. Der Handwerker schneidet die Silikonfuge auf, die die Fliesen vor der Abdeckplatte 11 von den übrigen trennt, und bringt zum Beispiel einen Saugnapf auf den Fliesen auf der Abdeckplatte 11 an. Nach der noch zu beschreibenden Demontage der Betätigungsplatte 17 kann nun die Abdeckplatte infolge der besonderen Ausgestaltung der Beschlagteile 12 nach vorne herausgezogen werden, sodass der Spülkasten 6 zugänglich ist. Dieser wiederum kann nun einschließlich des fest an ihm angebrachten Spülrohrs durch eine Kippbewegung entnommen werden, die in
Die beiden Teile sind in einem Überlappungsbereich 22 miteinander verschweißt. Diese bestehen dazu aus einem Dreilagenmaterial, nämlich einer mittleren thermoplastischen Elastomerfolie, die beidseits mit einem Polypropylen-Vlies beschichtet ist. Das Vlies ist in einer Richtung (in der Fläche) quer dehnbar und in der anderen dazu senkrechten Richtung so gut wie nicht.The two parts are welded together in an overlapping
Bei dem Verschweißen werden in der Überlappungszone 22 durch Ultraschall und Reibungswärme die jeweiligen thermoplastischen Kerne der beiden Teile 20 und 21 zumindest an ihrer Grenzfläche zueinander fließfähig und erzeugen somit die Schweißverbindung.During welding, in the overlapping
Der Überlappungsbereich 22 befindet sich in dem in
Ferner weist die Foliendichtung 2 aus
Unter dieser angedeuteten Abdeckplatte 11 erkennt man eine "Zick-Zack-Linienführung" des ersten Dichtungsteils, nämlich eine durch drei Falten gebildete und ungefähr V-förmig nach innen weisende Faltenbalgform. Diese ist durch drei vorgeprägte Faltlinien, eine obere Faltlinie 24, eine mittlere und in
Das nimmt Rücksicht auf das in dem Beispiel in
Der erste Dichtungsteil 20 der Foliendichtung 2 legt sich nicht nur wegen der vorgebügelten Falten 24 bis 26 relativ unproblematisch und ordentlich zusammen, sondern auch wegen der mechanischen Verstärkung infolge der Doppellagigkeit des Materials im Überlappbereich 22 (und der eventuellen Verdickung des Elastomerkerns infolge des Verschweißens oder, bei anderen Beispielen, durch Klebstoff). Damit ist gewissermaßen ein versteifter Rahmen gegeben.The
Das vliesbeschichtete Elastomermaterial ist hierbei für den ersten Dichtungsteil 20 so verarbeitet worden, dass die Richtung der maximalen Dehnbarkeit senkrecht zur Wandebene liegt, also in
Blasen unter Ausnutzung der elastischen Eigenschaften "wegdrücken" zu können. Grundsätzlich gilt das auch für in alle Richtungen gleich elastisch dehnbares Material, das einseitig elastische Material hat sich aber besonders bewährt. Gleichzeitig ist für solches Material typisch, dass es in der Richtung der maximalen Elastizität hinsichtlich eines Zusammenfaltens oder Zusammenschiebens am weichsten ist. Die in
Für das Anlegen und Glattstreichen des zweiten Dichtungsteils 21 im zweiten Flächenabschnitt spielt es erfahrungsgemäß keine wesentliche Rolle, in welcher Richtung die Elastizität vorliegt und man kann sich mit den Streichbewegungen auch daran anpassen.For the application and smoothing of the
Der zweiseitige Vliesbelag hat im zweiten Flächenabschnitt den Vorteil, einerseits das Ankleben auf der Beplankung der Leichtbauwand 10 zu erleichtern, vgl.
Wie anhand der
Die beschriebenen Eigenschaften und auch Verfahrensschritte gelten natürlich in gleicher Weise für andere Behältnisse, z. B. zum Leckageschutz bei einem Unterputzmischventil oder einer Unterputzarmatur oder einem Unterputzspülventil, aber auch zum dichten Einbau z. B. eines Möbel-ähnlichen Behältnisses oder eines Wand- oder Bodenablaufs.The described properties and also process steps of course apply in the same way for other containers, eg. As for leakage protection in a flush-mounted mixing valve or a concealed fitting or a concealed flush valve, but also for tight installation z. B. a furniture-like container or a wall or floor drain.
Das Material hat eine ungefähre Flächenmassendichte von 300 bis 350 g/m2 und ist in der elastischen Richtung auf das dreifache seiner unbelasteten Maße dehnbar, in der Richtung senkrecht dazu nur auf das eineinhalbfache, wobei beide Werte der Bruchdehnung entsprechen und damit Extrembedingungen. Die Stärke beträgt etwa 0,6 bis 0,7 mm.The material has an approximate surface mass density of 300 to 350 g / m 2 and is stretchable in the elastic direction to three times its unloaded dimensions, in the direction perpendicular thereto only to one and a half times, both values corresponding to the elongation at break and thus extreme conditions. The thickness is about 0.6 to 0.7 mm.
Im Übrigen gelten die obigen Ausführungen sinngemäß auch für die Foliendichtung 4, vgl. die
