Abstract

The device comprises a buoyant shutter (16) consisting of articulated profile bars (17), a winding shaft (15) onto which the shutter (16) is wound, and a drivable winding device. To simplify the drive and make it easier to remove and install the shutter for assembly and repair, the weight of the shutter reel (18) when arranged outside liquid rests on a winding device which is formed by two rollers (2, 3) and at least one belt (11, 12, 13) wrapped around the latter, the winding shaft (15) being freely displaceable in its vertical position. At least one of these rollers (2) is coupled to a drive. By virtue of the friction forces acting on the circumference of the shutter reel (18), the shutter (16) is extended and retracted at a linear speed which is always uniform (Fig. 1). According to an alternative embodiment, the shutter reel (18) when arranged below the level (24) of the liquid rests against the underside of the winding device, the buoyancy of the shutter reel (18) ensuring frictional engagement between the shutter (16) and the belt (11, 12, 13).

Description

Die Erfindung betrifft eine Abdeckvorrichtung für Schwimmbecken, mit einem aus gelenkig miteinander verbundenen Profilstäben bestehenden schwimmfähigen Rolladen und einer Wickelwelle zum Aufwickeln desselben.The invention relates to a covering device for swimming pools, with a floating roller shutter consisting of hinged profile bars and a winding shaft for winding the same.

Es ist bereits eine Abdeckvorrichtung bekannt, bei der ein oder mehrere Bänder zusammen mit dem Rolladen auf die Wikkelwelle aufrollbar sind, wobei durch das Aufwickeln der Bänder auf eine oberhalb der Wickelwelle angebrachte Vorrichtung der Rolladen von dem Rolladenwickel abgerollt und in die Abdeckstellung gebracht wird. Diese Vorrichtung benötigt einen komplizierten Antrieb, da sowohl die Wickelwelle als auch die Bänderwelle angetrieben sein müssen. Es ist ferner bereits eine Abdeckvorrichtung bekannt, bei der die Wickelwelle so hoch über oder so tief unter dem Wasserspiegel angeordnet ist, daß durch das Gewicht bzw. den Auftrieb des von dem Wickel bis zur Wasseroberfläche reichenden Rolladenteils der Rolladen selbsttätig abrollt. Diese. Vorrichtung hat den Nachteil, daß die Wickelwelle in einem bestimmten Mindestabstand von der Wasseroberfläche angeordnet sein muß, damit das Abwickeln ungestört vor sich geht und kein Aufblähen des Rolladenwickels in sich selbst. auftritt (DE-PS 1 236 164).A covering device is already known in which one or more strips can be rolled up together with the roller shutter onto the winding shaft, the roller shutter being rolled off the roller shutter roll and brought into the covering position by winding the strips onto a device mounted above the winding shaft. This device requires a complicated drive, since both the winding shaft and the ribbon shaft must be driven. It is also already known a cover device in which the winding shaft is arranged so high above or so deep below the water level that the roller shutter automatically rolls due to the weight or buoyancy of the roller shutter part extending from the winding to the water surface. These. The device has the disadvantage that the winding shaft must be arranged at a certain minimum distance from the water surface, so that the unwinding takes place undisturbed and there is no inflation of the roller shutter winding itself (DE-PS 1 236 164).

Es ist ferner bereits eine Schwimmbadabdeckung bekannt (US-PS 3 144 665), bei der der Rolladen unter Zuhilfenahme eines an diesem angreifenden und in der Nähe des Schwimmbeckenrandes liegenden Rades abgewickelt wird. Hierbei müssen jedoch sowohl die Wickelwelle als auch das Rad antreibbar ausgebildet sein.A swimming pool cover is also already known (US Pat. No. 3,144,665), in which the roller shutter is unwound with the aid of a wheel engaging on it and lying near the edge of the swimming pool. Here, however, both the winding shaft and the wheel must be designed to be drivable.

Der Erfindung liegt die Aufgabe zugrunde, eine Abdeckvorrichtung für Schwimmbecken der eingangs genannten Art zu schaffen, bei der sowohl zum Aufwickeln als auch zum Abwickeln lediglich eine Welle angetrieben zu sein braucht und bei der der Rolladenwickel leicht abnehmbar ist.The invention has for its object to provide a cover for swimming pools of the type mentioned, in which only one shaft needs to be driven both for winding and unwinding and in which the roller shutter winder is easily removable.

Eine Lösung dieser Aufgabe ist darin zu sehen, daß der Rolladenwickel bei seiner Anordnung außerhalb von Flüssigkeit auf einer Wickeleinrichtung aufliegt, die durch zwei Walzen und mindestens ein diese umschlingendes endloses Band gebildet ist,wobei die Wickelwelle mindestens in ihrer Höhenlage frei verschieblich gelagert ist und daß mindestens eine der Walzen mit einem Antrieb gekuppelt ist. Bei einer derartigen Abdeckung liegt der Rolladenwickel mit seinem Gewicht auf dem Band auf und wird auf diese Weise durch auf seinen Umfang wirkende Kräfte mit stets gleichbleibender Lineargeschwindigkeit aufgewickelt bzw. abgewickelt.A solution to this problem is to be seen in the fact that the roller shutter winding, when it is arranged outside of liquid, rests on a winding device which is formed by two rollers and at least one endless belt wrapping around it, the winding shaft being freely displaceable at least in its height and that at least one of the rollers is coupled to a drive. With such a cover, the roller shutter roll lies on the belt with its weight and is wound or unwound in this way by forces acting on its circumference at a constant linear speed.

Alternativ liegt der Rolladenwickel bei seiner Anordnung unterhalb von Flüssigkeit an derUnterseite einer Wickeleinrichtung an, die durch zwei Walzen und mindestens ein diese umschlingendes endloses Band gebildet ist, wobei mindestens eine der Walzen mit einem Antrieb gekuppelt ist. Auch dabei ist die Wickelwelle mindestens in ihrer Höhenlage frei verschieblich gelagert.Alternatively, the roller shutter roll, when it is arranged below liquid, rests on the underside of a winding device which is formed by two rolls and at least one endless belt wrapping around them, at least one of the rolls being coupled to a drive. Here, too, the winding shaft is freely displaceable at least in its height.

Die Wickeleinrichtung liegt vorzugsweise in der Ebene des Wasserspiegels des Schwimmbeckens. Dadurch lassen sich zusätzliche Führungseinrichtungen für den Rolladen vermeiden.The winding device is preferably in the level of the water level of the swimming pool. This means that additional guide devices for the roller shutters can be avoided.

Bei der zuerst genannten Ausführung kann die Wickeleinrichtung oberhalb des Wasserspiegels des Schwimmbeckens liegen, etwa auf einem Rand desselben angebracht sein.In the first-mentioned embodiment, the winding device can lie above the water level of the swimming pool, for example be attached to an edge thereof.

Gemäß einer Weiterbildung ist die Wickeleinrichtung um die Achse einer der Walzen schwenkbar gelagert. Beim Herausschwenken aus der Betriebsstellung kann der auf die Wickeleinrichtung aufgelegte Rolladenwickel daher von der Wickeleinrichtung herabgleiten bzw. der nach der Alterna= tivanordnung unterhalb des Flüssigkeitsspiegels angeordnete Rolladenwickel aus seiner Tauchlage auftauchen. Dies ist günstig bei der Montage oder für Wartungsabeiten.According to a further development, the winding device is mounted so as to be pivotable about the axis of one of the rollers. When swiveling out of the operating position, the roller shutter roll placed on the winding device can therefore slide down from the winding device or the roller shutter roll arranged below the liquid level according to the alternative arrangement can emerge from its immersion position. This is convenient for assembly or for maintenance.

Gemäß einer anderen Weiterbildung kann die Wickelwelle in horizontaler Richtung mit begrenzter Beweglichkeit gelagert sein, so daß sie in keinem Fall ungewollt von der Wickeleinrichtung freikommen kann.According to another development, the winding shaft can be mounted in the horizontal direction with limited mobility, so that it can under no circumstances be released from the winding device unintentionally.

Insbesondere um erhöhte Schubkräfte auf den Rolladen ausüben zu können, ist es vorteilhaft, wenn mindestens eine Andruckwalze vorgesehen ist, die mit derjenigen Walze zusammenwirrit, die der Ablaufstelle des Rolladens vom Rolla= denwickel benachbart ist.In particular, in order to be able to exert increased thrust forces on the roller shutters, it is advantageous if at least one pressure roller is provided which interacts with the roller which is adjacent to the outlet point of the roller shutter from the roller shutter roll.

Die Erfindung ist im folgenden anhand schematischer Zeichnungen an mehreren Ausführungsbeispielen ergänzend beschrieben.The invention is described below with reference to schematic drawings of several embodiments.

  • Fig. 1 zeigt einen Querschnitt durch eine Abdeckvorrichtung, bei der der Rolladenwickel über dem Wasserniveau liegt;Fig. 1 shows a cross section through a cover device, in which the roller shutter roll is above the water level;
  • Fig. 2 zeigt einen Querschnitt durch eine Abdeckvorrichtung, bei der der Rolladenwiekel unter dem Wasserniveau liegt ;Fig. 2 shows a cross section through a cover device, in which the roller shutter is below the water level;
  • Fig. 3 ist eine Draufsicht auf die Wickelvorrichtung nach Fig. 1;Fig. 3 is a plan view of the winding device of Fig. 1;
  • Fig. 4 zeigt im Querschnitt eine Wickelvorrichtung gemäß Fib. 2 mit einem Gegenlager.Fig. 4 shows in cross section a winding device according to Fi b . 2 with a counter bearing.

Die in den Figuren 1 und 2 dargestellte Abdeckvorrichtung umfaßt eine Wickeleinrichtung, welche zwei parallel und im Abstand zueinander angeordnete Walzen 2 und 3 aufweist, deren Wellen 4 und 5 drehbar in Seitenteilen 6 und 7 (Fig. 3) gelagert sind. Wie aus Fig. 3 zu erkennen ist, sind die beiden wellen an drei Stellen 8, 9 und 10, die in Längsrichtung der Wellen im Abstand voneinander liegen, ballig ausgebildet. Um diese balligen Stellen ist jeweils ein flexibles, endloses Band 11, 12 bzw. 13 gelegt. Die Welle, 4 ist mit einem Antrieb gekuppelt, wie durch die Antriebsscheibe 14 angedeutet ist.The cover device shown in Figures 1 and 2 comprises a winding device which has two parallel and spaced rollers 2 and 3, the shafts 4 and 5 are rotatably mounted in side parts 6 and 7 (Fig. 3). As can be seen from Fig. 3, the two shafts are spherical at three points 8, 9 and 10, which are spaced apart in the longitudinal direction of the waves. A flexible, endless band 11, 12 or 13 is placed around each of these spherical points. The shaft 4 is coupled to a drive, as indicated by the drive disk 14.

Auf die so gebildete Wickeleinrichtung ist ein auf eine Wickelwelle 15 aufgewickelter Rolladen 16 gelegt, der aus einzelnen miteinander gelenkig verbundenen Profilstäben 17 besteht (vgl. Fig. 1) . Fig. 1 zeigt den so gebildeten Rolladenwickel 18 im fast vollständig aufgewickelten Zustand. Man erkennt, daß die endlosen Bänder, beispielsweise 11, durch das Gewicht des Rolladenwickels 18 oben muldenförmig durchgebogen sind. Durch diese Durchbiegung wird erreicht, daß der Rolladenwickel nicht über eine der Walzen 2 oder 3 hinüberrollen kann, sondern immer in der Mulde liegen bleibt, selbst wenn der Rolladenwickel freischwebend und ohne horizontale Bewegungsbegrenzungen in dieser Mulde liegt.A roller shutter 16, which is wound onto a winding shaft 15 and is composed of individual profiled bars 17 which are connected to one another in an articulated manner, is placed on the winding device thus formed (cf. Fig. 1 shows the roller shutter roll 18 thus formed in the almost completely wound state. It can be seen that the endless belts, for example 11, are bent in a trough-shaped manner by the weight of the roller shutter roll 18 at the top. This deflection ensures that the roller shutter roll can not roll over one of the rollers 2 or 3, but always remains in the trough, even if the roller shutter roll is floating and without horizontal movement restrictions in this trough.

Um einen wirkungsvolleren Kraftschluß der Wickeleinrichtung mit dem Rolladen zu erreichen, sind gemäß Fig. 1 Andruckwalzen 19 vorgesehen, die jeweils in Richtung auf die zugeordnete Welle 4 vorgespannt sind und den dazwischenliegenden Rolladen 16 gegen die Walze 2 drücken. Diese AndruckWalzen sind zur Verbesserung der Übersicht in Fig. 3 fortgelassen.In order to achieve a more effective frictional connection of the winding device with the roller shutter, pressure rollers 19 are provided according to FIG. 1, which are each prestressed in the direction of the assigned shaft 4 and press the roller shutter 16 lying therebetween against the roller 2. These pressure rollers are omitted in FIG. 3 to improve the overview.

Von den in den Seitenteilen 6 und 7 gelagerten Wellen 4 und 5 ist nur die Lagerstelle für die Welle 5 durch eine Platte 20 abgedeckt, so daß die Welle 4 nicht ohne weiteres aus ihrer Lagerung herausgehoben werden kann, während die Lagerstelle 21 für die Welle 5 nach oben offen ist. Die bei= den Wellen 4 und 5 sind ferner an beiden Seiten mittels Platinen 22 und 23, die jeweils zwei Bohrungen aufweisen, miteinander gekuppelt. Auf diese Weise läßt sich die Walze 3 um die Welle 4 als Drehachse nach oben verschwenken, beispielsweise für Reparaturzwecke. Zur Vergrößerung des Auflagegewichts des Rolladenwickels 18 auf die Wickeleinrichtung kann der innerhalb der Wickelwelle 15 vorhandene geschlossene Hohlraum 28 mit Wasser gefüllt sein. Dadurch, daß die Wickeleinrichtung in einem Behälter 27 mit Entkeimungsflässigkeit liegt, kann ein Algenbewuchs des Rolladens 16 während des Auf- und Abwickelns bekämpft werden.Of the shafts 4 and 5 mounted in the side parts 6 and 7, only the bearing point for the shaft 5 is covered by a plate 20, so that the shaft 4 cannot easily be lifted out of its mounting while the bearing point 21 for the shaft 5 is open at the top. The at = the shafts 4 and 5 are further coupled on both sides by means of boards 22 and 23, each having two holes. In this way, the roller 3 can be pivoted upward about the shaft 4 as an axis of rotation, for example for repair purposes. To increase the bearing weight of the roller shutter roll 18 on the winding device, the closed cavity 28 present within the winding shaft 15 can be filled with water. Due to the fact that the winding device lies in a container 27 with disinfectant liquid, algae growth of the roller shutter 16 can be combated during the winding and unwinding.

Fig. 2 zeigt eine abgeänderte Ausführungsform, bei der der Rolladenwickel 18 unter der Wasseroberfläche 24 liegt und an der Unterseite der Walzen 2 und 3 und der darum liegenden Bänder anliegt, von denen in Fig. 2 nur das Band 11 dargestellt ist. Die Wickelwelle 15 ist durch zu beiden Seiten angeordnete vertikale, im Querschnitt U-förmige Profilteile 25 vertikal frei beweglich, jedoch in horizontaler Lage fixiert geführt.FIG. 2 shows a modified embodiment in which the roller shutter roll 18 lies below the water surface 24 and bears against the underside of the rollers 2 and 3 and the belts around them, of which only the belt 11 is shown in FIG. 2. The winding shaft 15 is vertically freely movable by vertical parts arranged on both sides and U-shaped in cross section, but fixed in a horizontal position.

Die Abdeckvorrichtung nach der Erfindung hat den Vorteil. daß sich ein und dieselbe Wickeleinrichtung für einen großen Bereich von Längen des Rolladens verwenden läßt. Je länger der Rolladen ist, desto größer ist auch der Durchmesser des Rolladenwickels und dessen Gewicht bzw. Auftrieb, so daß auch die Reibungskraft an den Bändern 11, 12 und 13 und an den Walzen 2 und 3 zunimmt. Wie man aus den Figuren erkennen kann, sind keine zusätzlichen Führungen für den Rolladen nötig, wenn derselbe in der Nähe des Wasserspiegels 24 von dem Rolladenwickel abläuft. Sowohl zum Aufwickeln als auch zum Abwickeln braucht lediglich eine Walze, beispielsweise die Walze 2, angetrieben zu werden. Daher läßt sich die Antriebseinrichtung einfach gestalten.The covering device according to the invention has the advantage. that one and the same winding device can be used for a large range of lengths of the roller shutter. The longer the roller shutter is, the larger the diameter of the roller shutter roll and its weight or buoyancy, so that the frictional force on the belts 11, 12 and 13 and on the rollers 2 and 3 also increases. As can be seen from the figures, no additional guides for the roller shutters are necessary if the latter is in the vicinity of the water level 24 runs off the roller shutter roll. Only one roller, for example roller 2, needs to be driven both for winding and for unwinding. Therefore, the drive device can be designed easily.

'.iie in Fig. 1 durch den gestrichelten Bereich 26 dargestellt ist, kann der Rolladen 16 auch mit entgegengesetzter Wickelrichtung aufgewickelt werden. Da der Antrieb des Rolladenwickels 18 immer durch an seinem Umfang wirkende Kräfte erfolgt, kann grundsätzlich kein Aufblähen des Wikkels in sich stattfinden.'.iie in Fig. 1 by the dashed area 26, the roller shutter 16 can also be wound with the opposite winding direction. Since the drive of the roller shutter roll 18 is always carried out by forces acting on its circumference, it is fundamentally impossible for the winding to expand in itself.

In Fig. 4 ist im Querschnitt eine Wickeleinrichtung 29 gemäß Fig. 2,mit einem Gegenlager zur Aufnahme der Auftriebskräfte des unter dem Wasserniveau angeordneten Rolladenwickels 30 dargestellt. Bei langen Schwimmbecken, beispielsweise mit einer Bahnlänge von 50 m, weist die zu einem Rolladenwickel 30 zusammengerollte Rolladenabdeckung einen beträchtlichen Durchmesser auf; dieser Rolladenwickel 30 erzeugt einen seiner Wasserverdrängung entsprechend großen Auftrieb, der gegen die Wickeleinrichtung 29 wirkt. Da insbesondere bei einem nachträglichen Einbau diese Auftriebskräfte nicht einfach in die Seitenwand 31 des Schwimmbeckens 32 eingeführt werden können, ist ein Gegenlager vorgesehen, das im wesentlichen aus einem dem maximalen Auftrieb entsprechenden Gegengewicht 33 und einem Verbindungssteg 34 zwischen diesem Gegengewicht und der Montageplatte 35 für die Wickeleinrichtung 29 besteht. In der dargestellten Ausführungsform sind Gegenlager, Verbindungssteg und Montageplatte in Form von U-förmigen Beton-Fertigteilelementen ausgebildet, die vor der Seitenwand 31 des Schwimmbeckens 32 auf den Beckenboden 36 aufgesetzt werden. Es kann aber auch aus einer Stahlkonstruktion bestehen. Die zum Beckeninneren hin offene Seite des U-förmigen Fertigteilelements wird durch eine abnehmbare Wand 37 abgedeckt. Bei dieser Ausgestaltung ist ein nachträglicher Einbau einer Rolladenabdeckung in bereits bestehende Schwimmbecken ohne Veränderungen der Beckeneinfassung und ohne störende Überbauten am Beckenrand ohne weiteres möglich. Außerdem bleibt die Wickeleinrichtung für Reparaturarbeiten leicht zugänglich. Der obere Schenkel des U-förmigen Fertigteilelements, der auch als Montageplatte für die Wickeleinrichtung 29 dient, sollte eine solche statische Festigkeit aufweisen, daß er begehbar ist. Um große Rolladenwickel und damit große Auftriebskräfte zu vermeiden, kann eine zweiteilige Abdeckvorrichtung mit jeweils einem Rolladenwickel an den beiden sich gegenüberliegenden Schmalseiten des Schwimmbeckens vorgesehen sein. Wenn die Wettkampfbahnlänge eines Schwimmbeckens von beispielsweise 50 m nicht durch den nachträglichen Einbau einer Unterwasser-Wickeleihrichtung an einer der Schmalseiten des Beckens zerstört werden soll, kann diese Wickeleinrichtung auch an einer der Langseiten des Schrrimmbeckens angeordnet werden.FIG. 4 shows in cross section a winding device 29 according to FIG. 2 with a counter bearing for absorbing the buoyancy forces of the roller shutter roll 30 arranged below the water level. In the case of long swimming pools, for example with a length of 50 m, the roller shutter cover rolled up to form a roller shutter roll 30 has a considerable diameter; this roller shutter roll 30 generates a lift corresponding to its water displacement, which acts against the winding device 29. Since these buoyancy forces cannot easily be introduced into the side wall 31 of the swimming pool 32, in particular when retrofitted, a counterbearing is provided which essentially consists of a counterweight 33 corresponding to the maximum buoyancy and a connecting web 34 between this counterweight and the mounting plate 35 for the Winding device 29 exists. In the illustrated embodiment, the counter bearing, connecting web and mounting plate are designed in the form of U-shaped prefabricated concrete elements which are placed on the pool floor 36 in front of the side wall 31 of the swimming pool 32. But it can also consist of a steel structure. The side of the U-shaped prefabricated element that is open towards the inside of the pool is covered by a removable wall 37. At this A subsequent installation of a roller shutter cover in existing swimming pools without changes to the pool surround and without disruptive superstructures at the pool edge is easily possible. In addition, the winding device remains easily accessible for repair work. The upper leg of the U-shaped prefabricated element, which also serves as a mounting plate for the winding device 29, should have such a static strength that it can be walked on. In order to avoid large roller shutter coils and thus large buoyancy forces, a two-part covering device, each with a roller shutter coil, can be provided on the two opposite narrow sides of the swimming pool. If the competition track length of a swimming pool of 50 m, for example, is not to be destroyed by the subsequent installation of an underwater winding direction on one of the narrow sides of the pool, this winding device can also be arranged on one of the long sides of the shrink pool.
