Description
Beschreibung Die bekannten Abdeckfolien haben den Nachteil'daß sie bei warmen Wetter die Innentemperatur der abgedeckten Räume stark ansteigen lassen,den oftmals benötigten Regen abhalten und beim Gießen angehoben werden müssen.Description The known cover films have the disadvantage that they let the internal temperature of the covered rooms rise sharply in warm weather, the often needed to keep out rain and have to be lifted when watering.
Erfindungsgemäß wird daher vorgeschlagen in die Abdeckfolie beispielsweise halbkugelförmige Vertiefungen zu drücken die in der Mitte geschlitzt sind und von Spannfäden umgeben werden.According to the invention it is therefore proposed, for example, in the cover film to press hemispherical indentations which are slit in the middle and of Tension threads are surrounded.
Durch die Ausführung wird erreicht,daß z.Beispiel eine wartungsfreie frühe Aussaat im Garten und Freiland möglich ist. Zudem kann ein Frühbeet ohne Anheben der Folienfenster gegossen werden.The implementation ensures that, for example, a maintenance-free early sowing in the garden and outdoors is possible. In addition, a cold frame can be used without lifting it the foil window can be cast.
In der Zeichnung ist ein AusSührun;sbeispiel dargestellt es zeigt Bild 1 Ausschnitt einer witterungsaktiven Abdeckfolie mit Verstärkungswulsten und Spanndrähten.In the drawing, an embodiment is shown, it shows Fig. 1 Section of a weather-active cover film with reinforcement beads and Tension wires.
Bild 2 bei kalter Temperatur spannt sich die Folie und schließt die Halbkugel. Image 2 at cold temperatures the film tensions and closes Hemisphere.
Bild 3 bei normalem Regen drückt das Wasser durch sein Eigengewicht den Schlitz auseinander. Fig. 3 In normal rain, the water pushes through its own weight the slit apart.
Bild 4 bei einem Platzregen fließt das überschüssige Wasser nach außen ab. Fig. 4 When there is a downpour, the excess water flows in outside.
Bild 5 bei warmer Temperatur gibt die Folie nach,die Halbkugel öffnet durch ihr von Wulsten erhöhtes Eigen-gewicht Bild 6 wird die Folie gedreht,so kann kein Wasser ein= dringen und der Schlitz wird durch das Eigen= gewicht der Halbkugel zusätzlich zugedrückt,sodaß sie wie eine normale Abdeckfolie verwendet werden kann. Fig. 5 At a warm temperature, the film gives way, the hemisphere opens Due to its own weight, which is increased by beads, Fig. 6, the film is rotated, so can no water can penetrate and the slot is made by the weight of the hemisphere additionally pressed so that it can be used like a normal cover sheet.
ei starkem Temperaturabfall bildet sich an der tiefsten Stelle der Halbkugel ein Tropfen Kondenswasser,sodaß bei Minusgraden der Schlitz zufriert.A sharp drop in temperature forms at the lowest point of the Hemisphere a drop of condensed water, so that the slot freezes over at sub-zero temperatures.
