Description

Die vorliegende Erfindung betrifft ein vorgefertigtes Schwimmbecken, welches aus Metall, insbesondere aus Edelstahl, aus Kunststoff, aus Kunststoff mit Keramikeinlage oder aus Betonfertigteilen gefertigt ist und über eine Wasserumwälzeinrichtung entweder ständig oder in regelmäßigen Zeitabständen Teile des Beckenwassers aus dem Schwimmbecken entfernt, durch einen Schmutzfilter leitet und wieder in das Becken zurückführt, wodurch eine Strömung im Beckenwasser durch die Umwälzung des Beckenwassers erzielt wird, wobei der Beckenboden zumindest teilweise entlang einer seiner Achsen gewölbt ist.The present invention relates to a prefabricated swimming pool, which is made of metal, in particular stainless steel, plastic, plastic with ceramic insert or precast concrete parts and via a water circulation either permanently or at regular intervals parts of the pool water from the swimming pool, passes through a dirt filter and returns to the basin, whereby a flow in the pool water is achieved by the circulation of the pool water, wherein the pool floor is at least partially curved along one of its axes.

Schwimmbecken aus Edelstahl oder aus Kunststoff, welche fabriksmäßig vorgefertigt sind und am Ort ihrer Aufstellung mittels Hebekran montiert werden, sind seit langem bekannt. Sie weisen genau so wie die aus Formsteinen gebauten Schwimmbecken, welche innen mit einer wasserdichten Folie ausgekleidet sind, den Nachteil auf, dass die umlaufende Wasserströmung im Bereich der Bodenecken und Bodenkanten aufgrund der Scherkräfte zwischen dem Beckenwasser und den Seitenwänden bzw. dem Beckenboden, in diesen Bereichen besonders verlangsamt ist. Dies begünstigt die Entstehung von Ablagerungen in diesen Bereichen und führt dort zu einer bevorzugten Ansammlung von Feststoffverunreinigungen, welche nur durch zusätzlichen Reinigungsaufwand entfernbar sind. Derartige Schwimmbecken sind beispielsweise in der US 3,660,957 A , der US 5,787,519 A der US 4,306,394 A oder der DE 11 80 114 B offenbart.Swimming pools made of stainless steel or plastic, which are factory prefabricated and mounted at the place of their installation by means of lifting crane, have long been known. They have the same as the built of molded blocks swimming pools, which are lined inside with a waterproof film, the disadvantage that the circumferential flow of water in the bottom corners and bottom edges due to the shear forces between the pool water and the side walls or the pelvic floor, in these Areas is particularly slowed down. This favors the formation of deposits in these areas and leads there to a preferred accumulation of solid contaminants, which are removable only by additional cleaning. Such swimming pools are for example in the US Pat. No. 3,660,957 , of the US 5,787,519 A of the US 4,306,394 A or the DE 11 80 114 B disclosed.

Das Dokument US 3,660,957 A offenbart die Merkmale des Oberbegriffs von Anspruch 1.The document US 3,660,957 A discloses the features of the preamble of claim 1.

Um hier zumindest größtenteils Abhilfe zu schaffen, stellt sich die vorliegende Erfindung die Aufgabe, das Schwimmbecken so auszugestalten, dass zumindest im Bereich einer Achse des Beckens, bevorzugt entlang seiner Längsachse keine erhöhten Scherkräfte auftreten.In order to remedy this, at least for the most part, the present invention has the object of designing the swimming pool in such a way that, at least in the region of an axis of the basin, preferably along its longitudinal axis, no increased shearing forces occur.

Schon bisher wurde versucht, dies durch entsprechende Abrundung der Bodenkanten zu erreichen, jedoch nur mit unzureichendem Erfolg. Trotz der Abrundung der Bodenkanten und Bodenecken treten nach wie vor in diesen Bereichen vermehrt Ansammlungen von Feststoffverunreinigungen auf bzw. kommt es in diesen Bereichen leichter zur Algenbildung als an den übrigen Begrenzungsflächen des Beckens. Der Grund liegt darin, dass die bekannten Kantenrundungen in ihrem Ausmaß viel zu gering sind, um einen Einfluss auf die Scherkräfte nehmen zu können. Die herkömmlichen Kantenrundungen haben meist eine Schenkellänge von 10 Zentimeter. Diese knappe Bemessung der Kantenrundung wird bei bekannten Schwimmbecken bewusst in Kauf genommen, um den optischen Eindruck eines flachen Beckenbodens nicht zu beeinträchtigen.So far, attempts have been made to achieve this by rounding off the bottom edges, but only with insufficient success. Despite the rounding of the bottom edges and bottom corners, accumulations of solid contaminants continue to occur in these areas, or algae is more easily formed in these areas than at the other boundary surfaces of the basin. The reason is that the known edge roundings are far too small in extent to be able to influence the shear forces. The conventional edge roundings usually have a leg length of 10 centimeters. This brief assessment of the edge rounding is deliberately accepted in known swimming pools in order not to affect the visual impression of a flat pelvic floor.

Die vorliegende Erfindung löst die gestellte Aufgabe dadurch, dass der Beckenboden tonnenförmig gewölbt ist und dass ein Schnitt durch den Beckenboden den Umriss eines Viertel- oder Halbkreises oder einer Viertel- oder Halbellipse zeigt, und der Beckenboden (1) unterhalb seiner gewölbten Fläche über diese Fläche verteilt mehrere im Abstand zueinander angeordnete Stützspanten (6, 7) aufweist. Natürlich kann der erfindungsgemäße Vorteil auch bei einem Beckenboden erzielt werden, dessen Radialschnitt den Umriss eines Viertelkreises oder einer Viertelellipse aufweist. Diese Ausführungsform ist jedoch entlang einer Bodenkante wieder mit den bekannten Nachteilen behaftet, hat aber den Vorteil, einen größeren Bereich mit entsprechender Tiefe für ungehindertes Schwimmen aufzuweisen. Diese Ausführungsvariante wird bevorzugt dann zur Anwendung kommen, wenn die freie Grundstücksfläche eher gering ist.The present invention solves this problem in that the pelvic floor is barrel-shaped and that a section through the pelvic floor shows the outline of a quarter or semicircle or a quarter or half ellipse, and the pelvic floor (1) below its curved surface over this area distributed has a plurality of spaced apart support ribs (6, 7). Of course, the advantage of the invention can also be achieved in a pelvic floor, the radial section has the outline of a quarter circle or a quarter ellipse. However, this embodiment is again associated with the known disadvantages along a bottom edge, but has the advantage of having a larger area with a corresponding depth for unhindered swimming. This embodiment variant is preferably used when the free plot area is rather low.

Bevorzugterweise deckt die gewölbte Fläche mindestens 25%, bevorzugt 50%, und insbesondere bevorzugt 100% der gesamten Bodenfläche ab. Dabei wird die Veränderung des optischen Erscheinungsbildes bewusst in Kauf genommen. Die Wölbung ist in einem so weiten Bereich ausgeführt, dass sie optisch klar erkennbar ist.Preferably, the curved surface covers at least 25%, preferably 50%, and most preferably 100% of the total bottom surface. The change in the visual appearance is deliberately accepted. The curvature is designed in such a wide range that it is optically clear.

Eine optimale Ausführung stellt ein Beckenboden dar, dessen Querschnitt die Form einer Halbellipse hat und der eine durchgehende Wölbung entlang seiner Querachse hat. Hier sind die beiden Längskanten aufgelöst und mittig befindet sich ein breiter Bereich mit ausreichender Schwimmtiefe, d.h. die Beckentiefe ermöglicht ein ungehindertes Brustschwimmen, ohne dass ein störender Kontakt der Füße beim Schwimmen mit dem Beckenboden zu befürchten ist.An optimal embodiment is a pelvic floor, whose cross section has the shape of a semi-ellipse and has a continuous curvature along its transverse axis. Here, the two longitudinal edges are dissolved and in the middle there is a wide area with sufficient swimming depth, i. the pelvic depth allows unhindered breaststroke, without fear of disturbing contact of the feet when swimming with the pelvic floor.

Diese optimale Ausführungsform ist in den Figuren in verschiedenen Varianten wiedergegeben. Darin zeigt Fig. 1 eine Beckenansicht von unten mit einem durchgehend gewölbten Beckenboden und senkrechten Seitenwänden, welche zugleich als Stützspanten ausgebildet sind.This optimal embodiment is shown in the figures in different variants. It shows Fig. 1 a pool view from below with a continuous curved pelvic floor and vertical side walls, which are also designed as supporting frames.

In Fig. 2 ist dieselbe Beckenansicht mit zusätzlichen Stützspanten über den Beckenboden verteilt zu sehen.In Fig. 2 the same pelvic view is to be seen with additional support frames distributed over the pelvic floor.

Fig. 3 zeigt eine Schrägansicht von oben des Beckens nach Fig. 2, wobei an einem Beckenrand eine Überlaufrinne angeformt ist. Selbstverständlich, können auch an mehreren Beckenrändern solche Überlaufrinnen vorhanden sein. Fig. 3 shows an oblique view from the top of the pelvis Fig. 2 , wherein at an edge of the pool an overflow channel is formed. Of course, such overflow channels may also be present on several pool edges.

In Fig. 4 ist eine weitere Variante mit einer sogenannten Römertreppe an einer Schmalseite dargestellt.In Fig. 4 Another variant is shown with a so-called Roman steps on a narrow side.

Die Figuren 5 und 6 zeigen zwei mögliche Beckenquerschnitte. Ein vollständig entlang einer Achse gewölbter Beckenboden nach Fig. 5 weist beispielsweise wie hier gezeigt, den Querschnitt einer Halbellipse auf. Eine weitere Variante hingegen weist den Querschnitt einer Viertelellipse mit angrenzendem Flachbereich wie in Fig. 6 gezeigt auf. Statt Halb- oder Viertelellipsen sind jedoch auch Halb- oder Viertelkreise denkbar.The Figures 5 and 6 show two possible tank cross sections. A pelvic floor completely curved along one axis Fig. 5 For example, as shown here, has the cross section of a semi-ellipse. A further variant, however, has the cross section of a quarter ellipse with adjacent flat area as in Fig. 6 shown on. Instead of half or quarter ellipses, however, half or quarter circles are also conceivable.

Eine optimale Ausführung stellt ein Beckenboden dar, dessen Querschnitt die Form einer Halbellipse hat und der eine durchgehende Wölbung entlang seiner Querachse hat. Hier sind die beiden Längskanten aufgelöst und mittig befindet sich ein breiter Bereich mit ausreichender Schwimmtiefe, d.h. die Beckentiefe ermöglicht ein ungehindertes Brustschwimmen, ohne dass ein störender Kontakt der Füße beim Schwimmen mit dem Beckenboden zu befürchten ist.An optimal embodiment is a pelvic floor, whose cross section has the shape of a semi-ellipse and has a continuous curvature along its transverse axis. Here, the two longitudinal edges are dissolved and in the middle there is a wide area with sufficient swimming depth, i. the pelvic depth allows unhindered breaststroke, without fear of disturbing contact of the feet when swimming with the pelvic floor.

Die Ausführungsvariante nach Fig. 1 besitzt einen entlang der Querachse durchgehend gewölbten Beckenboden 1 mit halbellipsenförmigem Querschnitt. Je nach gewünschter Beckenlänge setzt sich der Beckenboden 1 aus mehreren Segmenten 1' zusammen. Die beiden Schmalseiten werden von senkrechten Seitenwänden 2 und 3 gebildet, welche angeformte Stützspanten 4 und 5 besitzen, mit welchen das Becken gegen den Untergrund hin abgestützt wird.The embodiment according to Fig. 1 has a pelvic floor 1 with a semi-elliptical cross-section that is continuously curved along the transverse axis. Depending on the desired pelvic length, the pelvic floor 1 is composed of several segments 1 '. The two narrow sides are formed by vertical side walls 2 and 3, which have molded supporting ribs 4 and 5, with which the basin is supported against the ground.

In der bevorzugten Ausführungsvariante nach Fig. 2 sind zusätzlich über den Beckenboden 1 gleichmäßig weitere Stützspanten 6, 7 verteilt angeordnet, wodurch die Formstabilität des Beckens während der Hinterfüllung erhöht wird.In the preferred embodiment according to Fig. 2 are in addition to the pelvic floor 1 uniformly further support ribs 6, 7 arranged distributed, whereby the dimensional stability of the pelvis during backfill is increased.

Selbstverständlich kann das erfindungsgemäße Becken mit allen bekannten Zusatzeinrichtungen ausgestattet werden, etwa mit Skimmer 8 oder Überlaufrinnen 9, wie aus Fig. 3 hervorgeht. Es sind aber auch angeformte Senkkästen für Rollabdeckungen, integrierte Unterwasserscheinwerfer, Unterwassermassagedüsen und vieles mehr denkbar.Of course, the basin according to the invention can be equipped with all known ancillary equipment, such as skimmer 8 or overflow 9, as from Fig. 3 evident. But there are also molded caissons for roll covers, integrated underwater lights, underwater massage jets and much more conceivable.

Auch weitere Ausführungsvarianten sind möglich, etwa die in Fig. 4 dargestellte Römertreppe 10. Eine solche Einstiegstreppe lässt sich jedoch auch sehr vorteilhaft in eine gewölbte Längsseite integrieren.Other variants are possible, such as in Fig. 4 illustrated Roman steps 10. However, such an entry stairs can be very advantageous to integrate into a curved longitudinal side.

Es ist auch möglich das Becken so auszuführen, dass die Wölbung sowohl entlang der Querachse als auch entlang der Längsachse ausgebildet ist. Auch sind andere Varianten von Einstiegstreppen denkbar. Diese können auch im Eckbereich angeordnet sein.It is also possible to design the pelvis so that the camber is formed both along the transverse axis and along the longitudinal axis. Also other variants of entry stairs are conceivable. These can also be arranged in the corner area.
