Description

Die Erfindung bezieht sich auf ein Verfahren zur Schaffung einer Einstiegsöffnung in bestehende Badewannen.The invention relates to a method for creating a manhole in existing bathtubs.

Insbesonders aber nicht ausschließlich sind Altbauwohnungen mit Badewannen in den jeweiligen Badezimmern ausgestattet. Der Einbau von Duschtassen ergänzend oder anstatt von Badewannen ist erst seit kürzerer Zeit allgemein üblich.In particular, but not exclusively old apartments are equipped with bathtubs in the respective bathrooms. The installation of shower trays in addition to or instead of bathtubs has been common practice for a relatively short time.

Es ist allgemein bekannt, daß die Verwendung von Badewannen für ältere oder gebrechliche Personen problematisch ist. Zum Einsteigen in die Badewanne muß ein höherer Rand überstiegen werden; sowohl beim Ein- als auch beim Aussteigen aus der Badewanne besteht auf dem rutschigen Boden der Badewanne oder auf dem rutschigen Boden im Badezimmer die Gefahr des Ausrutschens. Darüber hinaus sind oftmals ältere Personen nicht mehr in der Lage die Füße über den hohen Badewannenrand zu heben.It is well known that the use of bathtubs for elderly or infirm persons is problematic. To get into the bathtub a higher edge must be exceeded; both when entering and exiting the bathtub there is a risk of slipping on the slippery floor of the bathtub or on the slippery floor in the bathroom. In addition, older people are often no longer able to lift their feet over the high edge of the bathtub.

Es besteht daher in der Praxis ein großes Bedürfnis nach Austausch der Badewanne gegen eine Duschtasse. Derartige Umbaumaßnahmen sind mit nicht unerheblichen Kosten verbunden, es muß die Badewanne vollständig abgerissen werden, wobei dabei zumeist die umgebenden Fliesen beschädigt werden. Ein weiteres Problem ist es, daß zumeist der Bereich des Badezimmers, der von der Badewanne bedeckt ist, nicht verfliest ist, sodaß beim Einbau einer Duschtasse auch Fliesenlegerarbeiten erforderlich sind. Zusätzlich müssen regelmäßig neue Anschluß- und Abflußleitungen verlegt werden. Dabei sind Stemmarbeiten notwendig, die mit einer großen Schmutzbelastung einhergehen.There is therefore a great need in practice for replacement of the bathtub against a shower tray. Such conversion measures are associated with significant costs, it must be completely demolished the bathtub, which usually the surrounding tiles are damaged. Another problem is that mostly the area of the bathroom, which is covered by the bathtub, is not tiled, so that when installing a shower tray tiling work is required. In addition, new connection and drain lines must be laid regularly. It requires caulking, which is associated with a large amount of dirt.

Darüber hinaus sind derartige Umbaumaßnahmen kostenintensiv, in der Praxis hat es sich gezeigt, daß insbesonders ältere Personen derartige Umbaukosten scheuen. Immer wieder wird das Argument gebracht, daß für die wenigen noch verbleibenden Jahre sich ein derartiger Umbau nicht lohnen würde.In addition, such conversion measures are costly, in practice, it has been shown that in particular older people shy away from such conversion costs. Again and again the argument is brought that for the few remaining years such a conversion would not be worthwhile.

Die Erfindung hat es sich daher zum Ziel gesetzt, ein Verfahren zum kostengünstigen Umbau einer bestehenden Badewanne in einen Duschbereich zu schaffen. Ein Ziel der Erfindung war es dabei, eine leichte Einstiegsmöglichkeit in bestehende Badewannen zu schaffen. Die Gefahr des Ausrutschens sollte dadurch minimiert werden. Darüber hinaus sollte der Charakter der Badewanne als Badewanne mit der Möglichkeit des Einlaufens von Wasser erhalten bleiben.The invention has therefore set itself the goal of creating a method for cost-effective conversion of an existing bathtub in a shower area. An object of the invention was to provide easy entry into existing bathtubs create. The risk of slipping should be minimized. In addition, the character of the bathtub should be preserved as a bathtub with the possibility of water ingress.

Dieses Ziel wurde dadurch erreicht, daß in die Badewanne eine Einstiegsöffnung geschnitten wird und in den Hohlraum zwischen Außenverkleidung der Badewanne und Badewanne ein Zwischenmittel eingebracht wird.This goal has been achieved by cutting a manhole into the bathtub and inserting an intermediate means into the cavity between the exterior of the bathtub and bathtub.

Eine Verbesserung des erfindungsgegenständlichen Verfahrens wird dadurch erreicht, daß in die Öffnung des Einstieges ein Türrahmen eingesetzt wird.An improvement of the inventive method is achieved in that a door frame is inserted into the opening of the entry.

Die Möglichkeit die Badewanne nicht nur als Duschtasse zu nützen, bliebt dadurch erhalten, wenn in den Türrahmen eine Türe eingebracht wird.The possibility not only to use the bathtub as a shower tray, survives thereby, if in the door frame a door is introduced.

Nachstehend wird die Erfindung anhand eines in Zeichnungen dargestellten Ausführungsbeispieles näher beschrieben, ohne auf dies Beispiel beschränkt zu sein.The invention will be described in more detail below with reference to an embodiment shown in the drawings, without being limited to this example.

Dabei zeigen die

  • Fig. 2 eine Ansicht einer herkömmlichen Badewanne, bei welcher das erfindungsgegenständliche Verfahren angewandt wurde,
  • Fig. 3 einen Schnitt entlang A-A in Fig. 2 und

The show
  • 1 is a view of a conventional bathtub,
  • 2 is a view of a conventional bathtub to which the subject method has been applied.
  • Fig. 3 is a section along AA in Fig. 2 and
  • Fig. 4 in view of a treated with the subject method bath in which a door frame was used.

Gemäß der Fig. 1 ist eine Badewanne 1 aus einem Badewannenkörper 2 aufgebaut. Nicht gezeigt sind die üblichen Armaturen (Kalt- und Warmwasserzulauf) und der Ablauf des Wassers.According to FIG. 1, a bathtub 1 is constructed from a bathtub body 2. Not shown are the usual fittings (cold and hot water supply) and the flow of water.

Der Badewannenkörper 2 ist auf eine hinter den Fliesen 3 befindliche Wand (nicht sichtbar) gestellt.The bathtub body 2 is placed on a wall located behind the tile 3 (not visible).

Gemäß der Fig. 2 wurde in die herkömmliche Badewanne 1 beispielsweise mit einer Trennscheibe (Diamantscheibe) durch den Badewannenkörper 2 selbst (der üblicherweise aus Stahlblech oder Polyester-Kunststoff besteht) und durch die, die Wanne umgebenden Trageelemente (Ziegelmauer 4, Fliesen 3) geschnitten.2 was in the conventional bathtub 1, for example, with a blade (diamond disc) through the bathtub body 2 itself (which usually consists of sheet steel or polyester plastic) and by the surrounding surrounding the tub support elements (brick wall 4, tiles 3) cut ,

Im gezeigten Ausführungsbeispiel wurde auf die Teilung der Fliesen 3 Rücksicht genommen, es entsteht dadurch ein optisch harmonischer Eindruck.In the illustrated embodiment, consideration was given to the division of the tiles 3, it creates a visually harmonious impression.

Handelt es sich um einen Badewannenkörper 2 aus einem Metall (z.B.: Stahlblech bei alten Badewannenkörpermodellen 2) ist es zweckmäßig, wenn die durch das Aufschneiden entstandenen Kanten 5 des Badewannenkörpers 2 mit einem Rostschutzmittel bestrichen werden.If it is a bathtub body 2 made of a metal (for example steel sheet in the case of old bathtub body models 2), it is expedient if the edges 5 of the bathtub body 2 created by the cutting are coated with a rust inhibitor.

In den durch das Aufschneiden entstandenen Hohlraum zwischen Badewannenkörper 2 und der Ziegelmauer 4 wird ein schnellhärtender Schaum 6 (z.B.: PU-Schaum) eingebracht. Der ausgehärtete Schaum 6 wurde mit einem Schneidewerkzeug (z.B.: Tapezierermesser) ausgeschnitten und somit der rechteckigen Form des Ausschnittes angepaßt.In the resulting from the cutting cavity between the bath body 2 and the brick wall 4, a fast-curing foam 6 (z.B .: PU foam) is introduced. The cured foam 6 was cut with a cutting tool (e.g., wallpapering knife) and thus adapted to the rectangular shape of the cutout.

Über den PU-Schaum 6 wurde anschließend eine handelsübliche Spachtelmasse (z.B.: Polyester- Spachtelmasse) aufgetragen um eventuelle Ungenauigkeiten des Ausschneidens mit dem Schneidewerkzeug auszugleichen. Zweckmäßiger weise wurde weiters die ausgehärtete Spachtelmasse mit feinem Schleifpapier abgeschliffen.A commercially available filler (eg. Polyester putty) was then applied over the PU foam 6 to compensate for any inaccuracies of cutting with the cutting tool. Conveniently, the cured putty was further sanded with fine sandpaper.

Zur Erzielung eines optisch schönen Eindruckes und zur Erzielung einer Feuchtigkeitsundurchlässigkeit ist es anschließend zweckmäßig, wenn über die abgeschliffene Polyester-Spachtelmasse ein wasserbeständiger Lack (z.B.: Bootslack) aufgebracht wird. Durch diesen wasserbeständigen Lack wird einerseits das Stahlblech vor Wasser geschützt und andererseits eine optische Abdeckung der Schnittkante erreicht. Der Lack kann in der Farbe des Badewannenkörpers 2 gehalten werden.In order to achieve a visually beautiful impression and to achieve a moisture impermeability, it is then expedient if a water-resistant paint (for example: boat paint) is applied over the ground polyester putty. This water-resistant paint on the one hand protects the steel sheet from water and on the other hand achieves optical coverage of the cut edge. The paint can be kept in the color of the bath body 2.

In der Fig. 3 (Schnitt A-A nach Fig. 2) ist der Badewannenkörper 2 sichtbar. Auf die Ziegelmauer 4 sind Fliesen 3 geklebt.In Fig. 3 (section AA of FIG. 2), the bathtub body 2 is visible. On the brick wall 4 tiles 3 are glued.

In den vormals bestehenden Hohlraum zwischen Badewannenkörper 2 und Ziegelmauer 4 wurde PU-Schaum 7 eingebracht.In the formerly existing cavity between bath body 2 and brick wall 4 PU foam 7 was introduced.

In der Fig. 4 wurde in die geschnittene Öffnung des Einstieges ein Türrahmen 8 eingesetzt. Der Türrahmen 8 weist einen Anschlag 9 auf. Nicht sichtbar sind Magneten, die eine Tür 10 am Anschlag 9 festhalten. Diese nicht sichtbaren Magneten bewirken einen ausreichend großen Vordruck auf die in den Türrahmen 8 eingelassene Dichtung. Wird Wasser in die Badewanne 1 eingelassen, entsteht eine genügende Abdichtung. Das Wasser dringt nicht zwischen Tür 10 und Türrahmen 8 aus der Badewanne 1.In Fig. 4, a door frame 8 was inserted into the cut opening of the Einstieges. The door frame 8 has a stop 9. Not visible are magnets that hold a door 10 on the stop 9. These invisible magnets cause a sufficiently large form on the recessed into the door frame 8 seal. If water is introduced into the bathtub 1, a sufficient seal is created. The water does not penetrate between the door 10 and door frame 8 from the bathtub. 1

Im Rahmen der Erfindung sind zahlreiche Abänderungen möglich, Insbesonders ist die Einbringung einer Türe und eines Türrahmens nicht notwendig. Auch ist der Anwendungsbereich nicht auf die gezeigte Badewanne beschränkt, auch Sitzbadewannen oder dergleichen können durch Anwendung des erfindungsgegenständlichen Verfahrens leichter betreten werden.In the context of the invention, numerous modifications are possible, especially the introduction of a door and a door frame is not necessary. Also, the scope is not limited to the bathtub shown, and hip baths or the like can be easily entered by applying the inventive method.
