Lateral pieces (5) abut with the outer end (7) on the Beckenumrandung (11) and are connected to the inner end (8) by means of a movable non-resilient restoring compound (15) to the middle piece (6). If the lateral pieces (5) were not curved at the outer end (7), the lateral piece (5) would rest on the basin edge (12) instead of on the pelvic border (11). This would have the consequence that the longitudinal edge (13) of the roll-up covering device instead of the pool border (11) abut into the air. The load of the roll-up covering device along the middle piece (6) takes over the swimming pool film (1) by the buoyancy and the expansion in the swimming pool film (1), Fig. 4 ,

  • the middle piece (6) is 2-3 times longer than the side pieces (5).
  • the middle piece (6) of lightweight plastic materials is also the composite support (2) is much lighter than the non-composite support made of aluminum. As a result, the handling of the roll-up cover device is easier.
  • the swimming pool film (1) and one-way valves (14) can be installed. These drain the rainwater from the surface of the pool liner (1) into the pool.
  • the pool sheet (1) has a similar specific gravity as the water and the middle piece (6) usually has a pipe shape and is closed at both ends which gives it a relatively high lift.
  • the tensioned roll-up covering device thus has enough buoyancy so that most of the rainwater flows through the one-way valves (14) into the basin.
  • the one-way valves (14) are located in the middle of the two composite supports (2).
  • the one-way valves (14) are locked in the load of the swimming pool film (1) and do not allow the entry of the pool water to the surface of the swimming pool film (1). You can also lock the one-way valves (14) so that the rainwater does not mix with the pool water. In that case the rainwater is removed by means of a pump.
  • the composite carrier (2) stretches when abutting on the already rolled collar (17) because the middle piece (6) and the two lateral pieces (5) and attached to the pool sheet (1) in a straight line are, Fig. 5 , Extended composite beam (2) stretches the pool sheet (1) along the composite beam (2).
  • the lateral piece (5) abuts with its inner end (8) to the water surface.
  • the lateral pieces (5) are usually shorter than in and out of aluminum tubes and can withstand the stresses of about 100Kg without plastic deformation.

  • the composite carrier (2) extends after the end of the load because of the movable elastic restoring compounds (16) and returns to its original shape.
  • the middle piece (6) is shorter than the composite support (2), and since most of the load takes over the pool sheet (1), the middle piece (6) may be of a smaller diameter aluminum tube than the uncompounded backing. As a result, the composite carrier (2) is lighter which allows easier handling of the roll-up cover device.
  • the composite support (2) where the composite support (2) consists only of the two lateral pieces (5) connected by means of a movable resilient return connection (16), the two lateral pieces (5) are not exposed the water surface, Fig. 8 , Composite carrier (2) from both side pieces (5) is stretched out like a non-composite carrier.

  • the length of a lateral piece (5) is only half of the length of the carrier in one piece and thereby the lateral piece (5) is much more resilient than the carrier in a piece if both of the same material and the same shape are in the cut. Since the lateral piece (5) can withstand the maximum allowable load of the carrier in one piece with a smaller diameter, the lateral piece (5) is also lighter due to lower material consumption, and thereby easier handling of the roll-up covering device is made possible.

Abstract

Die aufrollbare Abdeckvorrichtung besteht aus Schwimmbadfolie, quer zur Längsrichtung ausgerichtete zusammengesetzte Träger, einen Aufwickelrohr und Spanner der Schwimmbadfolie. Der zusammengesetzte Träger besteht aus drei Stücken und zwar aus zwei seitlichen Stücken und aus einem mittleren Stück. Die zwei seitlichen Stücke sind mittels einer beweglichen unelastischen oder beweglichen elastisch rückstellenden Verbindung mit den mittleren Stück verbunden. Bei einer Belastung der aufrollbaren Aufrollvorrichtung stosst der mittlere Stück auf die Wasseroberfläche an und die Schwimmbadfolie übernimmt durch den Auftrieb die meiste Belastung und nicht der zusammengesetzter Träger selbst.The roll-up covering device consists of a swimming pool film, composite carriers oriented transversely to the longitudinal direction, a winding tube and tensioner of the swimming pool film. The composite support consists of three pieces, namely two side pieces and one middle piece. The two lateral pieces are connected to the middle piece by means of a movable inelastic or movable elastically restoring connection. With a load of the roll-up retractable device, the middle piece pushes on the water surface and the swimming pool film takes over the buoyancy most of the load and not the composite carrier itself.

Description

Die Erfindung betrifft eine aufrollbare Abdeckvorrichtung für ein Schwimmbecken welche aus einer Abdeckfolie an die quer zur Längsrichtung ausgerichteten Träger besteht.The invention relates to a roll-up covering device for a swimming pool which consists of a cover to the transversely oriented to the longitudinal direction carrier.

Aufgabe der Erfindung ist es eine aufrollbare Abdeckvorrichtung der eingangs genannten Art weiter zu verbessern, wobei diese grosse Belastungen übernehmen kann, ist trotzdem leicht vom Gewicht und ist praktisch für den Transport.The object of the invention is to further improve a roll-up covering device of the type mentioned, wherein this can take over large loads, is still light in weight and is convenient for transport.

Es sind viele aufrollbare Abdeckvorrichtungen bekannt wie z.B. DE3906275 (A1 ).There are many roll-up covering devices known, for example DE3906275 (A1 ).

Bei allen bekannten Lösungen braucht man um die Tragfähigkeit zu vergrössern stärkere Träger. Durch stärkere Träger, in der Regel Aluminium-Rohre, vergrösserte Tragfähigkeit erhöht auch das Gewicht der aufrollbaren Abdeckvorrichtung und erschwert das Aufrollen. Dadurch ist eine einfache Benutzung der aufrollbaren Abdeckvorrichtung die als Schutz vor Schmutz und als Kinderschutz dient erschwert. Bei allen bekannten Lösungen ist auch das Paket in dem man die aufrollbare Abdeckvorrichtung transportiert mindestens so lang wie die Länge der eingebauten Träger.In all known solutions to increase the carrying capacity stronger carrier needs. Increased load capacity, usually aluminum tubes, increased load capacity also increases the weight of the roll-up cover and makes it difficult to roll up. As a result, a simple use of the roll-up cover device which serves as protection against dirt and as child protection is difficult. In all known solutions, the package in which one transports the roll-up cover at least as long as the length of the built-in carrier.

Aufgabe der Erfindung wird bei der eingangs genannten aufrollbaren Abdeckvorrichtung durch den Austausch von Träger in einem Stück mit einem Träger bestehend aus mehreren Stücken gelöst. Zwei Ausführungsbeispiele des Gegenstandes der Erfindung werden anhand der Zeichnungen näher beschrieben, dabei zeigen:

Die aufrollbare Abdeckvorrichtung besteht aus Schwimmbadfolie (1), quer zur Längsrichtung ausgerichtete zusammengesetzte Träger (2), einen Aufwickelrohr (3) und Spanner (4) der Schwimmbadfolie, Fig. 1.The roll-up covering device consists of swimming pool film (1), transverse to the longitudinal direction aligned composite carrier (2), a winding tube (3) and tensioner (4) of the swimming pool film, Fig. 1 ,

Zusammengesetzter Träger (2) besteht aus drei Stücken und zwar aus zwei seitlichen Stücken (5) und einen mittleren Stück (6) wie auf dem Fig. 2. Der mittlere Stück (6) und beide seitlichen Stücke (5) sind in einer geraden Linie an die Schwimmbadfolie (1) angebracht. Die innere Endstücke der seitlichen Stücke (8) sind mittels einer beweglichen Verbindung (9) an den mittleren Stück (6) verbunden. Bei einer kostengünstigeren Ausführung des Zusammengesetzten Trägers (2) kann der Zusammengesetzte Träger (2) nur aus den beiden seitlichen Stücken (5) die mittels einer beweglichen Verbindung (9) verbunden sind bestehen, Fig. 8.
Je nach dem ob die bewegliche Verbindung (9) auch elastisch rückstellend ist oder nicht sind zwei Ausführungen der aufrollbaren Abdeckvorrichtung möglich.Composite support (2) consists of three pieces, namely two side pieces (5) and a middle piece (6) as on the Fig. 2 , The middle piece (6) and both side pieces (5) are attached in a straight line to the swimming pool sheet (1). The inner end pieces of the side pieces (8) are connected by a movable connection (9) to the middle piece (6). In a more cost effective embodiment of the composite support (2), the composite support (2) may consist only of the two lateral pieces (5) which are connected by means of a movable connection (9), Fig. 8 ,
Depending on whether the movable connection (9) is also resiliently resetting or not two versions of the roll-up cover device are possible.

Ausführung der aufrollbaren Abdeckvorrichtung mit einer beweglichen Verbindung (9) die nicht elastisch rückstellend ist.
Bei einer beweglichen nicht elastisch rückstellenden Verbindung (15) zwischen den mittleren Stück (6) und beiden seitlichen Stücken (5) legt sich der mittlere Stück an die Wasseroberfläche, Fig. 3. Eine einfache Ausführung einer beweglichen nicht elastisch rückstellenden Verbindung (15) ist auch schon ein plastisches Band welches mit einem Ende an innere Ende des seitlichen Stückes (8) und mit dem anderen Ende an das Ende des mittleren Stückes (10) gebunden ist. Eine andere einfache Ausführung einer beweglichen nicht elastisch rückstellenden Verbindung (15) ist auf die Schwimmbadfolie (1) angebrachter Saum in welchen beide seitlichen Stücke (5) und der mittlere Stück (6) eingesteckt sind. Eine bewegliche nicht elastisch rückstellende Verbindung (15) kann auch ein Gelenk sein. Beide seitlichen Stücke (5) sind am äusseren Ende (7) leicht gekrümmt. Seitliche Stücke (5) liegen mit dem äusseren Ende (7) an der Beckenumrandung (11) an und sind mit dem inneren Ende (8) mittels einer beweglichen nicht elastisch rückstellenden Verbindung (15) an den mittleren Stück (6) verbunden. Würden die seitlichen Stücke (5) am äusseren Ende (7) nicht gekrümmt sein so würde der seitliche Stück (5) statt an der Beckenumrandung (11) auf den Beckenrand (12) aufliegen. Das hätte zur Folge das der Längsrand (13) der aufrollbaren Abdeckvorrichtung statt auf die Beckenumrandung (11) anzuliegen in die Luft ragte.
Die Belastung der aufrollbaren Abdeckvorrichtung entlang des mittleren Stückes (6) übernimmt die Schwimmbadfolie (1) durch den Auftrieb und der Dehnung in der Schwimmbadfolie (1), Fig. 4.Execution of the roll-up cover device with a movable connection (9) which is not resiliently resetting.
In a movable non-resilient restoring joint (15) between the middle piece (6) and both side pieces (5), the middle piece lays against the water surface, Fig. 3 , A simple embodiment of a movable non-elastically restoring compound (15) is also already a plastic band which is bound with one end to the inner end of the side piece (8) and with the other end to the end of the middle piece (10). Another simple embodiment of a movable non-resilient restoring connection (15) is on the pool sheet (1) mounted hem in which both side pieces (5) and the middle piece (6) are inserted. A movable non-resilient return connection (15) may also be a hinge. Both lateral pieces (5) are slightly curved at the outer end (7). Lateral pieces (5) abut with the outer end (7) on the Beckenumrandung (11) and are connected to the inner end (8) by means of a movable non-resilient restoring compound (15) to the middle piece (6). If the lateral pieces (5) were not curved at the outer end (7), the lateral piece (5) would rest on the basin edge (12) instead of on the pelvic border (11). This would have the consequence that the longitudinal edge (13) of the roll-up covering device instead of the pool border (11) abut into the air.
The load of the roll-up covering device along the middle piece (6) takes over the swimming pool film (1) by the buoyancy and the expansion in the swimming pool film (1), Fig. 4 ,

Die Dehnung in der Schwimmbadfolie (1) in der Längsrichtung der zusammengesetzten Träger (2) übernehmen die zusammengesetzte Träger (2) und die Dehnung quer zur Längsrichtung der zusammengesetzten Träger (2) die Spanner (4). Die Belastung der aufrollbaren Abdeckvorrichtung entlang des mittleren Stückes (6) hat keine dauerhafte Wirkung auf den mittleren Stück (6) da dieser meistens aus leichten elastischen Kunststoffmaterialien, welche sehr große Beugungen ohne plastische Deformation erlauben, besteht. Die Belastung der aufrollbaren Abdeckvorrichtung entlang der seitlichen Stücke (5) übernehmen die seitlichen Stücke (5). Die seitlichen Stücke (5) sind meistens leichte bis Im lange Aluminium-Rohre welche die Belastungen bis ca. 100Kg aushalten können ohne sich dabei plastisch zu deformieren und tragen zum Gewicht der aufrollbaren Abdeckvorrichtung wenig bei. Der mittlere Stück (6) ist 2-3 mal länger als der seitliche Stücke (5). Ist der mittlere Stück (6) aus leichten Kuntstoffmaterialien ist auch der zusammengesetzter Träger (2) wesentlich leichter als der nichtzusammengesetzter Träger aus Aluminium. Dadurch wird die Handhabung der aufrollbaren Abdeckvorrichtung leichter.
In die Schwimmbadfolie (1) können auch Einwegventile (14) eingebaut sein. Diese lassen das Regenwasser von der Oberfläche der Schwimmbadfolie (1) in das Schwimmbecken durch. Die Schwimmbadfolie (1) hat eine ähnliche spezifische Dichte wie das Wasser und der mittlere Stück (6) hat üblicherweise eine Rohr-Form und ist an beiden Enden geschlossen was ihm relativ viel Auftrieb verleiht. Die gespannte aufrollbare Abdeckvorrichtung hat dadurch genug Auftrieb damit das meiste Regenwasser durch die Einwegventile (14) ins Becken abfließt. Die Einwegventile (14) befinden sich in der Mitte der zwei zusammengesetzten Träger (2). Die Einwegventile (14) werden bei der Belastung der Schwimmbadfolie (1) gesperrt und erlauben nicht das Eintreten des Schwimmbecken-Wassers an die Oberfläche der Schwimmbadfolie (1). Man kann die Einwegventile (14) auch sperren damit sich das Regenwasser mit dem Schwimmbecken-Wasser nicht mischt. In dem Fall wird das Regenwasser Mittels einer Pumpe entfernt.
Beim Aufrollen der aufrollbarer Abdeckvorrichtung streckt sich der zusammengesetzte Träger (2) beim anstossen auf den schon zusammengerollten Bund (17) aus weil der mittlere Stück (6) und die beiden seitlichen Stücke (5) and die Schwimmbadfolie (1) in einer geraden Linie angebracht sind, Fig. 5. Ausgestreckter zusammengesetzter Träger (2) dehnt die Schwimmbadfolie (1) entlang des zusammengesetzten Trägers (2). Würde die Schwimmbadfolie (1) nicht entlang des zusammengesetzten Trägers (2) ausgestreckt sein so würde sich beim Zusammenrollen die aufrollbare Abdeckvorrichtung nicht in ein Bund sondern in eine formlose Form zusammenrollen. Ausführung der aufrollbaren Abdeckvorrichtung mit einer beweglichen Verbindung (9) die elastisch rückstellenden ist.
Bei einer beweglichen elastisch rückstellenden Verbindung (16) zwischen den mittleren Stück (6) und beiden seitlichen Stücken (5) liegt der mittlere Stück (6) nicht auf die Wasseroberfläche auf, Fig. 6. Zusammengesetzter Träger (2) ist ausgestreckt wie ein nicht zusammengesetzter Träger. Beide seitlichen Stücke (5) brauchen am äusseren Ende (7) nicht gekrümmt sein da die an die Beckenumrandung (11) horizontal anlegen.
Bei einer Belastung der aufrollbaren Abdeckvorrichtung entlang der seitlichen Stücke (5) beugen sich zuerst die beiden beweglichen elastisch rückstellenden Verbindungen (16), Fig. 7. Der seitliche Stück (5) stosst mit seinem inneren Ende (8) an die Wasseroberfläche auf. Die seitlichen Stücke (5) sind üblicherweise kürzer als Im und aus Aluminium-Rohren und können die erwrteten Belastungen von ca. 100Kg ohne plastische Deformation aushalten. Bei einer Belastung der aufrollbaren Aufrollvorrichtung entlang des mittleren Stückes (6) werden sich zuerst die beiden beweglichen elastisch rückstellenden Verbindungen (16) beugen. Der mittlere Stück (6) liegt dabei an die Wasseroberfläche auf und die meiste Belastung übernimmt die Schwimmbadfolie (1) in Form des Auftriebes und der Dehnung in der Schwimmbadfolie (1). Der zusammengesetzter Träger (2) streckt sich nach beenden der Belastung wegen der beweglichen elastisch rückstellenden Verbindungen (16) aus und nimmt wieder seine ursprüngliche Form an. Da der mittlere Stück (6) kürzer ist als der zusammengesetzter Träger (2) und da die meiste Belastung die Schwimmbadfolie (1) übernimmt kann der mittlere Stück (6) aus einem im Durchmesser kleineren Aluminium-Rohr sein als der nicht zusammengesetzter Träger. Dadurch ist der zusammengesetzter Träger (2) leichter was eine einfachere Handhabung der aufrollberer Abdeckvorrichtung ermöglicht.
Bei einer kostengünstigeren Ausführung des Zusammengesetzten Trägers (2) wo der Zusammengesetzte Träger (2) nur aus den beiden seitlichen Stücken (5) die mittels einer beweglichen elastisch rückstellenden Verbindung (16) verbunden sind besteht, liegen die beiden seitlichen Stücke (5) nicht auf die Wasseroberfläche auf, Fig. 8. Zusammengesetzter Träger (2) aus beiden seitlichen Stücken (5) ist ausgestreckt wie ein nicht zusammengesetzter Träger.
Bei einer Belastung der aufrollbaren Abdeckvorrichtung entlang der seitlichen Stücke (5) beugt sich die bewegliche elastisch rückstellende Verbindungen (16). Die beiden seitlichen Stücke (5) stossen mit dem inneren Ende (8) an die Wasseroberfläche auf. Das Nachsetzen der seitlichen Stücke (5) verhindert an die seitlichen Stücke (5) angebrachte Schwimmbadfolie (1) durch den Auftrieb, Fig. 9. Die Länge eines seitlichen Stückes (5) beträgt nur die hälfte der Länge des Trägers in einem Stück und dadurch ist der seitliche Stück (5) wesentlich belastbarer als der Träger in einem Stück wenn beide aus gleichen Material und gleicher Form im Schnitt sind. Da der seitliche Stück (5) die maximale erlaubte Belastung des Trägers in einem Stück bei einem kleineren Durchmesser aushält ist der seitliche Stück (5) wegen geringeres Materialverbrauchs auch leichter und dadurch ist eine einfachere Handhabung der aufrollbarer Abdeckvorrichtung ermöglicht. Der zusammengesetzter Träger (2) streckt sich nach beenden der Belastung wegen der beweglich elastisch rückstellender Verbindung (16) aus und nimmt wieder seine ursprüngliche Form an.
Eine einfache bewegliche elastisch rückstellende Verbindung (16) ist auch schon ein flexibler Band oder ein flexibler Rohr der mit einem Ende an/in das innere Ende des seitlichen Stückes (8) und mit dem anderen Ende an/in das Ende des mittleren Stückes (10) oder an/in das innere Ende des seitlichen Stückes (8) gebunden ist.
Eine bewegliche elastisch rückstellende Verbindung (16) bei welcher man die Beugekraft des zusammengesetzten Trägers (2) verstellen kann besteht aus einem U-Profil (19), zwei Achsen (20), zwei Stiften (22) mit dem Gewinde am Ende, zwei Unterlegscheiben (24) und zwei Muttern (23), Fig. 12 und Fig. 14. Beide Achsen (20) sind jede an einem Ende des U-Profils (19) quer zu deren Längsachse an U-Profil (19) durch die Löcher (26) fixiert, Fig. 11, Fig. 12. An beide Achsen (20) sind Stücke (18) durch die Löcher (25) befestigt, Fig. 10. Stück (18) kann sowohl ein seitlicher Stück (5) als auch ein mittleres Stück (6) sein. U-Profil (19) hat in der Mitte zwei Öffnungen (27) in welche beide Stifte (22) eingelassen sind. Auch die Stücke (18) haben Öffnungen (29) durch welche die Stifte (22) durchgehen. Zwischen der Öffnung (29) und der Feder (21) welche an dem Stift (22) eingesteckt ist befindet sich eine Unterlegscheibe (24) welche der Feder (21) ein Vorschub durch die Öffnung (29) verhindert. Am Ende des Stiftes (22) ist eine Mutter (23) angeschraubt welche das Stück (18) mittels Feder (21) in die Richtung U-Profil (19) drückt, Fig. 14. Bei einer Belastung des Stückes (18) dreht sich das Stück (18) um die Achse (20) und drückt die Feder (21) zusammen, Fig. 13 und Fig. 15. Winkel zwischen den beiden Stücken (18) ändert sich. Nach dem Beenden der Belastung streckt sich die Feder (21) wieder aus in die Ausgangsposition und der Winkel zwischen beiden Stücken (18) ist wieder gleich wie vor der Belastung. Im Stück (18) gegenüber der Öffnung (29) befindet sich auch eine Öffnung (30) welche leichteres zuschrauben der Mutter (23) ermöglicht, Fig. 10.
In der Schwimmbadfolie (1) sind beim Einsatz von der beweglichen elastisch rückstellenden Verbindung (16) die Abwässerungslöcher notwendig. Diese Abwässerungslöcher sind gleich wie bei einer aufrollbaren Abdeckvorrichtung mit nicht zusammengesetzten Trägern.
Zusammengesetzter Träger (2) ist beim Zusammenrollen der aufrollbaren Abdeckvorrichtung ausgestreckt da auf ihn während dieses Vorganges keine Belastung auftritt. Das Aufrollen ist gleich wie beim aufrollbaren Abdeckvorrichtungen mit nicht zusammengesetzten Trägern.
Ein zusammengesetzter Träger (2) besteht aus Stücken die nicht länger sind als die Hälfte des Trägers in einem Stück. Dadurch ist es auch möglich die aufrollbere Abdeckvorrichtung für den Transport viel kleiner zu Verpacken. Wenn man eine bewegliche Verbindung (9) mit eine nicht bewegliche Verbindung ersetzt bekommt man einen zusammengesetzten Träger mit den ähnlichen Eigenschaften des Trägers in einem Stück jedoch mit der Möglichkeit diesen kleiner zu verpacken. Um die Verpackung noch zu verkleinern kann man die seitlichen Stücke (5) aus zwei Stücken zusammensetzen welche eine unbewegliche Verbindung verbindet. Eine einfache unbewegliche Verbindung ist schon ein Rohr in welches zwei Stücke(18) eingesteckt sind. Der Aufwickelrohr (3) ist mittels unbeweglicher Verbindung wegen des Transportes aus mindestens zwei Stücken zusammengesetzt.The elongation in the swimming pool film (1) in the longitudinal direction of the composite supports (2) take over the composite supports (2) and the elongation transverse to the longitudinal direction of the composite supports (2) takes over the tensioners (4). The loading of the roll-up covering device along the middle piece (6) has no lasting effect on the middle piece (6) since this is usually made of light elastic plastic materials, which allow very large deflections without plastic deformation. The load of the roll-up covering device along the lateral pieces (5) take over the lateral pieces (5). The side pieces (5) are mostly light to long aluminum tubes which can withstand the loads up to 100Kg without deforming plastically and contribute to the weight of the roll-up cover little. The middle piece (6) is 2-3 times longer than the side pieces (5). If the middle piece (6) of lightweight plastic materials is also the composite support (2) is much lighter than the non-composite support made of aluminum. As a result, the handling of the roll-up cover device is easier.
In the swimming pool film (1) and one-way valves (14) can be installed. These drain the rainwater from the surface of the pool liner (1) into the pool. The pool sheet (1) has a similar specific gravity as the water and the middle piece (6) usually has a pipe shape and is closed at both ends which gives it a relatively high lift. The tensioned roll-up covering device thus has enough buoyancy so that most of the rainwater flows through the one-way valves (14) into the basin. The one-way valves (14) are located in the middle of the two composite supports (2). The one-way valves (14) are locked in the load of the swimming pool film (1) and do not allow the entry of the pool water to the surface of the swimming pool film (1). You can also lock the one-way valves (14) so that the rainwater does not mix with the pool water. In that case the rainwater is removed by means of a pump.
When rolling up the roll-up cover device, the composite carrier (2) stretches when abutting on the already rolled collar (17) because the middle piece (6) and the two lateral pieces (5) and attached to the pool sheet (1) in a straight line are, Fig. 5 , Extended composite beam (2) stretches the pool sheet (1) along the composite beam (2). If the swimming pool film (1) were not stretched along the composite carrier (2), the roll-up covering device would not curl up into a bundle but into an informal shape during rolling up. Execution of the roll-up cover device with a movable connection (9) which is elastically resetting.
In a movable elastic restoring connection (16) between the middle piece (6) and both side pieces (5), the middle piece (6) is not on the water surface, Fig. 6 , Composite support (2) is stretched out like a non-composite support. Both lateral pieces (5) do not need to be curved at the outer end (7) because they attach horizontally to the pelvic border (11).
Upon loading of the roll-up covering device along the lateral pieces (5), first the two flexible elastically restoring joints (16) bend, Fig. 7 , The lateral piece (5) abuts with its inner end (8) to the water surface. The lateral pieces (5) are usually shorter than in and out of aluminum tubes and can withstand the stresses of about 100Kg without plastic deformation. Upon loading of the roll-up retractor along the middle piece (6), first, the two movable elastically restoring joints (16) will bend. The middle piece (6) rests against the water surface and the swimming pool film (1) takes over most of the load in the form of buoyancy and expansion in the swimming pool film (1). The composite carrier (2) extends after the end of the load because of the movable elastic restoring compounds (16) and returns to its original shape. Since the middle piece (6) is shorter than the composite support (2), and since most of the load takes over the pool sheet (1), the middle piece (6) may be of a smaller diameter aluminum tube than the uncompounded backing. As a result, the composite carrier (2) is lighter which allows easier handling of the roll-up cover device.
In a more cost effective embodiment of the composite support (2) where the composite support (2) consists only of the two lateral pieces (5) connected by means of a movable resilient return connection (16), the two lateral pieces (5) are not exposed the water surface, Fig. 8 , Composite carrier (2) from both side pieces (5) is stretched out like a non-composite carrier.
Upon loading of the roll-up cover device along the lateral pieces (5), the movable elastically restoring joints (16) bends. The two lateral pieces (5) abut with the inner end (8) on the water surface. The Nachsetzen the lateral pieces (5) prevents attached to the side pieces (5) swimming pool film (1) by the buoyancy, Fig. 9 , The length of a lateral piece (5) is only half of the length of the carrier in one piece and thereby the lateral piece (5) is much more resilient than the carrier in a piece if both of the same material and the same shape are in the cut. Since the lateral piece (5) can withstand the maximum allowable load of the carrier in one piece with a smaller diameter, the lateral piece (5) is also lighter due to lower material consumption, and thereby easier handling of the roll-up covering device is made possible. The composite carrier (2) extends after completion of the load because of the movable elastic restoring connection (16) and returns to its original shape.
A simple movable elastic return connection (16) is also already a flexible band or tube having one end on / in the inner end of the side piece (8) and the other end on / in the end of the middle piece (10 ) or at / in the inner end of the lateral piece (8) is bound.
A movable resilient return connection (16) in which one can adjust the flexing force of the composite support (2) consists of a U-profile (19), two axles (20), two threaded end pins (22), two washers (24) and two nuts (23), FIGS. 12 and 14 , Both axes (20) are each fixed at one end of the U-profile (19) transversely to the longitudinal axis of the U-profile (19) through the holes (26), Fig. 11 . Fig. 12 , On both axes (20) pieces (18) through the holes (25) are fixed, Fig. 10 , Piece (18) can be both a side piece (5) and a middle piece (6). U-profile (19) has two openings (27) in the middle in which both pins (22) are embedded in the middle. The pieces (18) have openings (29) through which pass the pins (22). Between the opening (29) and the spring (21) which is inserted on the pin (22) there is a washer (24) which prevents the spring (21) from advancing through the opening (29). At the end of the pin (22) a nut (23) is screwed which presses the piece (18) by means of spring (21) in the direction U-profile (19), Fig. 14 , When the piece (18) is loaded, the piece (18) rotates about the axis (20) and compresses the spring (21), FIGS. 13 and 15 , Angle between the two pieces (18) changes. After termination of the load, the spring (21) extends back to the starting position and the angle between the two pieces (18) is again the same as before the load. In the piece (18) opposite the opening (29) is also an opening (30) which allows easier screwing the nut (23), Fig. 10 ,
In the swimming pool film (1), the drainage holes are necessary when using the movable elastic restoring connection (16). These drainage holes are the same as in a roll-up cover device with non-composite straps.
Composite carrier (2) is stretched when rolling up the roll-up cover since there is no load on it during this process. The rolling up is the same as in the roll-up cover devices with non-composite carriers.
A composite carrier (2) consists of pieces no longer than half of the carrier in one piece. As a result, it is also possible to pack the roll-up cover device much smaller for transport. Replacing a movable connection (9) with a non-movable connection gives a composite support with the similar characteristics of the support in one piece but with the possibility to pack it smaller. To make the package even smaller you can put the side pieces (5) of two pieces which connects a stationary connection. A simple immovable connection is already a tube in which two pieces (18) are inserted. The take-up tube (3) is assembled by means of immovable connection because of the transport of at least two pieces.
