Description

Die Erfindung betrifft eine Badewanne oder eine Duschtasse aus einem Kunststoff mit einer in den Boden davon eingearbeiteten Verstärkungseinlage, eine derartige Verstärkungseinlage, die Verwendung dieser Verstärkungseinlage zur Herstellung eines verstärkten Bodenbereiches einer Badewanne oder Duschtasse und ein Verfahren zur Herstellung einer Badewanne oder Duschtasse.The invention relates to a bathtub or a shower tray from a Plastic with a in the bottom of it incorporated Reinforcement insert, such a reinforcing insert, the Use of this reinforcing insert for producing a reinforced floor area of a bath or shower tray and a Method of making a bathtub or shower tray.

Nachstehend soll nur noch auf Badewannen Bezug genommen werden, wobei dieser Begriff Badewanne auch eine Duschtasse oder ähnliches mit umfasst.In the following, only bathtubs will be referred to, this term bathtub also a shower tray or similar includes.

Badewannen werden heute entweder aus einem emaillierten Blech oder aus einem Kunststoffmaterial hergestellt. Die zum Benutzer zeigende Seite der Badewanne wird dabei häufig aus Acrylglas bzw. Sanitärglas hergestellt. Bei diesem Acrylglas handelt es sich um PMMA (Polymethylmethacrylat).Bathtubs are today either made of enamelled sheet metal or made of a plastic material. The pointing to the user Side of the bathtub is often made of acrylic glass or sanitary glass produced. This acrylic glass is PMMA (Polymethyl methacrylate).

Zur Herstellung der zum Benutzer zeigenden Seite der Badewanne wird eine dünne PMMA-Kunststoffplatte durch Tiefziehen in die eigentlichen Grundform gebracht. Das so erhaltene Gebilde ist jedoch instabil. Zur Verstärkung wird dann auf die untere Seite und somit auf die von Benutzer abgewandte Seite eine oder mehrere Lagen aus einem Kunststoffmaterial aufgebracht, beispielsweise durch Aufspritzen oder durch Auflegen etc., wie z.B. in GB-A-2 040 676.To make the user facing side of the bathtub a thin PMMA plastic plate by deep drawing into the actual Basic form brought. However, the structure thus obtained is unstable. to Reinforcement is then on the lower side and thus on the User side facing one or more layers of one Applied plastic material, for example by spraying or by hanging up etc., such as in GB-A-2 040 676.

Es ist nun bekannt, im besonders belasteten Bodenbereich und somit in dem Bereich, in dem der Benutzer zum Stehen kommt bzw. steht, eine Verstärkungseinlage einzuarbeiten bzw. einzulaminieren. Diese Verstärkungseinlage wird zweckmäßigerweise vollständig in das Kunststoffmaterial eingebettet, so dass diese Verstärkungseinlage von außen nicht sichtbar ist. Als Verstärkungseinlage wird üblicherweise eine Holzplatte oder eine Pressspanplatte eingesetzt. It is now known in the heavily loaded ground area and thus in the area where the user comes to a standstill Incorporate reinforcing insert or einzulaminieren. These Reinforcement insert is suitably completely in the Embedded plastic material, so this reinforcement insert of is not visible on the outside. As a reinforcing insert is usually a wooden plate or a pressboard used.

Diese bekannten Verstärkungseinlagen haben den Nachteil, dass die Verbindung zu dem Kunststoffmaterial ungenügend ist. Dies kann einerseits durch vorhandene Feuchtigkeit oder andererseits durch Lufteinschlüsse bedingt sein. Zudem neigt das Kunststoffmaterial dazu, an den Seiten der Verstärkungseinlage wegzufließen, so dass die Randbereiche dieser bekannten Verstärkungseinlage bei der fertigen Duschwanne von außen noch zu sehen sind etc.These known reinforcing inserts have the disadvantage that the Connection to the plastic material is insufficient. This can on the one hand by existing moisture or on the other hand by Air pockets be conditional. In addition, the plastic material tends to flow away at the sides of the reinforcing insert, so that the Edge regions of this known reinforcing insert in the finished Shower tray can still be seen from the outside etc.

Aufgabe der vorliegenden Erfindung ist es, eine verbesserte Verstärkungseinlage für Badewannen oder Duschtassen bereitzustellen, die auf einfache Weise in den Boden eingearbeitet werden kann und sicher und fest damit verbunden ist.Object of the present invention is to provide an improved Provide reinforcing insert for bathtubs or shower trays, which can be easily incorporated into the soil and securely and firmly connected with it.

Gelöst wird diese Aufgabe durch die Lehre der Ansprüche.This problem is solved by the teaching of the claims.

Bei der erfindungsgemäßen Badewanne besitzt die Verstärkungseinlage eine im wesentlichen flache Grundplatte, die im eingearbeiteten Zustand zur Wanne hin zeigt. Auf der bodenabgewandten Fläche der Grundplatte sind Wände vorhanden, welche die Fläche der Grundplatte in mehrere Abteile unterteilen. Pro Abteil ist mindestens ein durchgehendes Loch in der Grundplatte ausgenommen. Beim Einbau dieser Verstärkungseinlage in den Boden einer Badewanne wird diese Verstärkungseinlage mit ihrer Grundplatte an den unverstärkten oder noch nicht vollständig verstärkten Bodenbereich der Badewanne angelegt. Dann wird das zur Herstellung des verstärkten Boden eingesetzte Kunststoffmaterial in die Abteile und natürlich auch in die Löcher in der Grundplatte eingebracht. Die Löcher werden dabei zweckmäßigerweise vollständig vom diesem Kunststoffmaterial ausgefüllt, während die Abteile als solche zumindest teilweise und vorzugsweise ebenfalls vollständig ausgefüllt werden.In the bath according to the invention has the reinforcing insert a substantially flat base plate, the incorporated state pointing to the tub. On the floor-facing surface of the base plate There are walls which make up the surface of the base plate in several Divide compartments. Per compartment is at least one through hole in excluded from the base plate. When installing this Reinforcing insert in the bottom of a bathtub becomes this Reinforcement insert with its base plate to the unreinforced or not yet fully reinforced floor area of the bathtub created. Then that will be used to make the reinforced floor used plastic material in the compartments and of course in the Holes introduced in the base plate. The holes will be there suitably completely from this plastic material filled out, while the compartments as such at least partially and preferably also completely filled out.

Dieses Kunststoffmaterial verbindet sich beim Ausreagieren bzw. beim Aushärten bzw. haftet an dem Bodenbereich der Badewanne und stellt somit, indem der Kunststoff durch die Löcher quasi hindurch ragt, eine formschlüssige Verbindung der Verstärkungseinlage mit dem Boden dar, wenn der Kunststoff ausgehärtet ist bzw. ausreagiert hat. Durch das Ausfüllen der Abteile als solche wird sichergestellt, dass der Boden über eine ausreichende Dicke verfügt und den mechanischen Anforderungen standhält. Durch die Grundplatte wird zudem erreicht, dass die Reaktionswärme des in dem Abteil reagierenden Kunststoffmaterials zum Boden hin isoliert wird, wodurch verhindert wird, dass von oben gesehen in der Badewanne im Bodenbereich farbliche Veränderungen oder andere Veränderungen auftreten, die durch eine zu große Wärmeentwicklung hervorgerufen werden.This plastic material combines when reacting or when Curing or sticking to the bottom area of the bathtub and posing thus, by the plastic practically protrudes through the holes, a positive connection of the reinforcing insert with the ground, when the plastic has hardened or has reacted. By the Filling the compartments as such will ensure that the floor is over has sufficient thickness and mechanical requirements withstand. By the base plate is also achieved that the Heat of reaction of the plastic material reacting in the compartment is insulated to the ground, which prevents being from above seen in the bathtub in the floor area changes in color or other changes that occur due to a too large Heat development are caused.

Unter einem Kunststoffmaterial wird im Rahmen der hier vorliegenden Unterlagen das Reaktionsgemisch zur Herstellung des ausreagierten bzw. ausgehärteten Kunststoffes verstanden.Under a plastic material is in the context of the present here Substrate the reaction mixture to produce the reacted or cured plastic understood.

Beim Einarbeiten der Verstärkungseinlage wird diese im übrigen zweckmäßigerweise auf eine auf den Boden der Badewanne außen aufgebrachte erste Lage aus einem Kunststoffmaterial aufgelegt. Durch die vorhandenen Löcher kann die Luft bzw. können evtl. vorhandene Blasen beim Andrücken der Verstärkungseinlage von unten gegen den Boden entweichen. Eventuell sich bildende Hohlräume unterhalb der Grundplatte können beim Ausfüllen der Abteile mit dem Kunststoffmaterial, das in diesem Zustand noch mehr oder weniger flüssig ist, ausgefüllt werden. Dazu dringt dieses Kunststoffmaterial durch die Löcher hindurch und füllt evtl. Hohlräume aus. Für alle diese Vorgänge wird die Badewanne üblicherweise auf den Kopf gestellt, so dass das aufgebrachte und in die Abteile eingefüllte Kunststoffmaterial alleine durch die Schwerkraft durch die Löcher und in ggf. vorhandene Hohlräume unterhalb der Grundplatte eindringen kann. Zweckmäßigerweise wird die Menge des Kunststoffmaterials derart bemessen, dass die Verstärkungseinlage vollständig in das Kunststoffmaterial eingearbeitet ist bzw. vollständig von diesem verhüllt wird. Das Kunststoffmaterial wird dabei zweckmäßigerweise lagenweise, beispielsweise durch Aufsprühen oder andere bekannte Techniken aufgebracht und in die Abteile eingetragen.When incorporating the reinforcing insert this is otherwise expediently on a on the bottom of the bathtub outside applied first layer of a plastic material. By the existing holes can be the air or possibly existing Bubbles when pressing the reinforcing insert from below against the Escape soil. Possibly forming cavities below the Base plate can be filled with the Plastic material that in this condition is more or less is liquid, to be filled out. For this penetrates this plastic material through the holes and fills possibly cavities. For all these Incidentally, the bathtub is usually turned upside down, so that the applied and filled in the compartments plastic material solely by gravity through the holes and in possibly existing Cavities can penetrate below the base plate. Conveniently, the amount of plastic material is so measured that the reinforcing insert completely into the Plastic material is incorporated or completely covered by this becomes. The plastic material is expediently in layers, for example, by spraying or other known techniques applied and registered in the compartments.

Nach einer bevorzugten Ausführungsform sind alle Abteile vollständig von Wänden umgrenzt, wobei alle Wände vorzugsweise die gleiche Höhe haben. Weiterhin bevorzugt wird die gesamte Fläche der Grundplatte in Abteile mit in etwa gleicher Größe unterteilt. Die Größe der Abteile und die Größe des Loches pro Abteil werden zweckmäßigerweise derart gewählt, dass einerseits eine gute Verbindung mit dem Bodenbereich der Badewanne erreicht wird und andererseits eine möglichst optimale Isolierung der auftretenden Reaktionswärme sichergestellt wird. Die entsprechenden Abmessungen der Abteile und des Loches können von einem Fachmann ohne weiteres in Abhängigkeit von dem eingesetzten Kunststoff in geeigneter Weise gewählt werden. Gewünschtenfalls können auch zwei, drei, vier oder mehr als vier Löcher pro Abteil vorhanden sein. Die Form der Abteile, die man auch als eine Art Waben bezeichnen könnte, ist dabei beliebig. Vorzugsweise ist die Grundfläche dieser Abteile quadratisch.In a preferred embodiment, all compartments are complete bounded by walls, with all walls preferably the same Have height. Further preferred is the entire surface of the Base plate divided into compartments with approximately the same size. The size the compartments and the size of the hole per compartment will be suitably chosen such that on the one hand a good Connection with the floor area of the bathtub is achieved and on the other hand, the best possible isolation of occurring Reaction heat is ensured. The corresponding dimensions The compartments and the hole can easily be obtained by a person skilled in the art depending on the plastic used in a suitable manner to get voted. If desired, two, three, four or There will be more than four holes per compartment. The shape of the compartments, which could also be described as a kind of honeycomb, is arbitrary. Preferably, the base of these compartments is square.

Die Verstärkungseinlage ist vorzugsweise aus einem Kunststoffmaterial hergestellt und vorzugsweise einstückig, insbesondere spritzgeformt. Es kann sich dabei um jeden beliebigen Kunststoff (z. B. Polycarbonat) handeln, beispielsweise einen thermoplastischen oder einen duroplastischen Kunststoff, wobei ein thermoplastischer Kunststoff bevorzugt ist. Insbesondere wird Sanitär-Acrylglas (PMMA = Polymethylmethacrylat) eingesetzt.The reinforcing insert is preferably made of a plastic material manufactured and preferably in one piece, in particular injection-molded. It can be any plastic (eg polycarbonate) act, for example, a thermoplastic or a thermosetting plastic, being a thermoplastic is preferred. In particular, sanitary acrylic glass (PMMA = Polymethylmethacrylate).

Die Erfindung wird im folgenden anhand der Zeichnungen näher erläutert. Von den Zeichnungen zeigen:

Die in der Figur 1 gezeigte Badewanne 1 ist aus Sanitär-Acrylglas gefertigt. Auf der unteren Seite und somit auf der vom Benutzer wegzeigenden Seite ist die Badewanne 1 insbesondere im Bereich des Bodens 2 verstärkt. In diesen Boden 2 ist eine Verstärkungseinlage 3 eingebracht. Diese Verstärkungseinlage kann dabei aus nur einer derartigen Verstärkungseinlage 3 oder aus mehreren nebeneinander angeordneten, jedoch separaten Verstärkungseinlagen 3 aufgebaut sein. Mit anderen Worten, die Verstärkungseinlage insgesamt kann aus mehreren Segmenten von Verstärkungseinlagen 3 bestehen.The bath 1 shown in Figure 1 is made of sanitary acrylic glass manufactured. On the lower side and thus on the user pointing away is the bathtub 1 in particular in the area of Bodens 2 reinforced. In this bottom 2 is a reinforcing insert. 3 brought in. This reinforcing insert can only one such reinforcing insert 3 or more side by side arranged, but separate reinforcing inserts 3 constructed be. In other words, the overall reinforcing insert may turn off consist of several segments of reinforcing inserts 3.

Die Verstärkungseinlage 3 ist insbesondere in der Figur 2 gezeigt und besteht aus einer dünnen Grundplatte 4 und mehreren Wänden 5, die derart angeordnet sind, dass die gesamte Fläche der Grundplatte 4 in in etwa gleiche quadratische Abteile 6 unterteilt. Pro Abteil 6 ist ein in der Grundplatte 4 ausgenommenes Loch 7 vorhanden, das in etwa in der Mitte der Abteile 6 angeordnet ist.The reinforcing insert 3 is shown in particular in FIG. 2 and consists of a thin base plate 4 and several walls 5, the are arranged such that the entire surface of the base plate 4 in in divided about the same square compartments 6. Pro compartment 6 is one in the Base plate 4 excluded hole 7 available, which is approximately in the Center of the compartments 6 is arranged.

Zur Herstellung der erfindungsgemäßen Badewanne 1 wird als erstes der obere Teil der Badewanne 1 durch Tiefziehen einer dünnen Kunststoffplatte aus Sanitär-Acrylglas hergestellt und erhält dabei ihre Grundform. Die so hergestellte Grundform hat nach oben hin und somit auf der zum Benutzer hin zeigenden Seite eine glatte Oberfläche.For the preparation of the bathtub 1 according to the invention is the first the upper part of the bath 1 by deep drawing a thin Plastic plate made of sanitary acrylic glass and receives their Basic form. The basic shape thus produced has upwards and thus on the side facing the user a smooth surface.

Auf die gegenüberliegende Seite bzw. Fläche dieser Grundform werden eine oder mehrere Lagen aus einem Kunststoffmaterial aufgebracht. Dazu wird die durch Tiefziehen hergestellte Grundform auf den Kopf gestellt. Zum Einarbeiten der Verstärkungseinlage 3 in den Boden 2 der Badewanne 1 werden dann eine oder mehrere erste Lagen aus Sanitär-Acrylglas auf diese Grundform aufgesprüht. Anschließend wird eine Verstärkungseinlage 3 oder werden mehrere Verstärkungseinlagen 3 mit ihrer unteren Seite 9 der Grundplatte 4 auf den Boden 2 aufgelegt und an das noch nicht ausreagierte Kunststoffmaterial angepresst. Danach wird weiteres Kunststoffmaterial durch Aufspritzen in die Abteile 6 eingebracht, bis die Verstärkungseinlage(n) 3 vollständig in das Kunststoffmaterial eingebettet ist(sind). Als Kunststoffmaterial wird ein Methylmethacrylatharzsystem verwendet, das mit einer 2-Komponenten-Airless-Spritzanlage verarbeitet wird. Dabei kann sogar auf den Einsatz von Glasfaser-Rovings verzichtet werden, die bei anderen bekannten Verfahren zum Aufbringen von Kunststoffmaterial eingesetzt werden.Be on the opposite side or surface of this basic shape applied one or more layers of a plastic material. For this purpose, the basic shape produced by deep drawing is turned upside down posed. To incorporate the reinforcing insert 3 in the bottom 2 of the Bathtub 1 will then be one or more first layers of plumbing acrylic glass sprayed on this basic form. Subsequently, a Reinforcement insert 3 or more reinforcing 3 with her lower side 9 of the base plate 4 placed on the bottom 2 and pressed against the not yet reacted plastic material. After that is further plastic material by spraying in the compartments. 6 introduced until the reinforcing insert (s) 3 completely in the Plastic material is embedded (are). As plastic material is a Methyl methacrylate resin system used with a 2-component airless spray gun is processed. It may even be on the insert Fiberglass rovings are dispensed with, which in other known Method for applying plastic material can be used.

Das Kunststoffmaterial füllt dabei die Löcher 7 und auch die Abteile 6 aus. Die Verstärkungseinlage(n) 3 besteht/bestehen ebenfalls aus Sanitär-Acrylglas. Aufgrund der chemischen Verwandtschaft der für die Verstärkungseinlage 3 und die Badewanne 1 eingesetzten Kunststoffmaterialien kommt es zu einem dauerhaften, festen Verbund. Wegen dieser Gegebenheit ist es ohne weiteres möglich, das Herstellungsverfahren zu automatisieren.The plastic material fills the holes 7 and also the compartments 6 out. The reinforcing insert (s) 3 is / are also made Sanitary acrylic glass. Due to the chemical relationship of the for Reinforcement insert 3 and the bath 1 used Plastic materials make it a durable, solid composite. Because of this condition, it is easily possible that Automate manufacturing process.

Die Wände 5 der Verstärkungseinlage 3 besitzen im übrigen alle die gleiche Höhe und umgrenzen die Abteile 6 vollständig, so dass vollständig voneinander separierte Abteile 6 vorhanden sind.The walls 5 of the reinforcing insert 3, moreover, all have the same height and completely circumscribe the compartments 6, so that completely separated compartments 6 are present.
