The housing has an upper with one edge having S-shaped cross-section, accommodating Z-section edge of the bottom part. The S-section edge (3) forms an undercut at between 10 and 40 deg. to the vertical. The top rib (6) of the Z-section edge (4) is at the same angle. In the unloaded state, the width (11) of the undercut (5) is approximately 2.2mm. The join between the middle (7) and top (6) ribs of the Z-section is via a curve (12) bearing against the spring free end of the top part (9) and a second higher one (13) in the opposite direction and extending through a smaller angle.

Description

Die Erfindung betrifft einen Rolladenkasten mit wenigstens einem Oberteil und einem Unterteil sowie seitlichen Blendenkappen, wobei ein Ende des Oberteils einen S-förmigen Aufnahmeabschnitt für einen Z-förmigen Verbindungsabschnitt aufweist, der am zugewandten Ende des Unterteils ausgebildet ist.The invention relates to a roller shutter box at least an upper part and a lower part as well side bezel caps with one end of the top an S-shaped receiving section for a Z-shaped Has connecting section, the facing end of the lower part is formed.

Ein Rolladenkasten dieser Art ist beispielsweise aus der EP-A-0 137 133 bekannt. Die Verbindung von Ober- und Unterteil ist dabei ziemlich kompliziert gewählt, was vor allem hohe Herstellkosten nach sich zieht. Außerdem ist ein weites Schwenken des Unterteils erforderlich, wenn es vom Oberteil getrennt werden soll.A roller shutter box of this type is, for example, from the EP-A-0 137 133 known. The connection of upper and Bottom part is chosen quite complicated, what before entails high manufacturing costs. Besides, is a wide swiveling of the lower part is required if it should be separated from the top.

Aus der Druckschrift EP-A-0 309 370 ist ebenfalls ein Rolladenkasten bekannt, bei dem das Oberteil und das Unterteil durch Zusammenstecken miteinander verbunden werden. Diese bekannte Ausführung hat vor allem den Nachteil, daß kein sicherer Sitz zwischen Ober- und Unterteil gegeben ist, insbesondere nicht, wenn die Rolladenkästen sich über eine größere Länge erstrecken.From EP-A-0 309 370 is also a Roller shutter box known, in which the upper part and Lower part connected by plugging together will. This well-known version has the Disadvantage that no secure fit between top and Lower part is given, especially not if the Roller shutter boxes extend over a greater length.

Der Erfindung liegt die Aufgabe zugrunde, einen Rolladenkasten der eingangs näher bezeichneten Art zu schaffen, der eine möglichst unkomplizierte, mit vertretbarem Aufwand herstellbare lösbare Verbindung von Oberteil und Unterteil aufweist und eine schnelle und bequeme Montage bzw. Demontage erlaubt.The invention has for its object a Roller shutter box of the type specified at the beginning create the most uncomplicated, with reasonable effort producible releasable connection of Has top and bottom part and a quick and easy assembly and disassembly allowed.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der S-förmige Aufnahmeabschnitt eine Hinterschneidung unter einem Winkel gegen die Senkrechte von α = 10 - 40° bildend gestaltet ist, daß der obere Steg des Z-förmigen Verbindungsabschnitts einen Winkel β gegen die Senkrechte von ebenfalls 10 - 40° aufweist, wobei die Winkel α und β entweder gleich groß sind oder der Winkel β größer als der Winkel α ausgebildet ist, daß der Spalt an dem S-förmigen Aufnahmeabschnitt im entspannten Zustand ca. 2,2 mm breit ausgebildet ist und daß die Verbindung zwischen dem Mittelsteg und dem oberen Steg des Z-förmigen Verbindungsabschnitts über einen am freien, federnden Ende des Aufnahmeabschnitts anliegenden Bogen und einen zweiten, gegenläufigen Bogen, der in der Ausdehnung kleiner als der Bogen ist, erfolgt.This object is achieved in that the S-shaped receiving section is designed to form an undercut at an angle to the vertical of α = 10-40 °, that the upper web of the Z-shaped connecting section forms an angle β to the vertical of likewise 10 - 40 °, wherein the angles α and β are either the same size or the angle β is larger than the angle α , that the gap on the S-shaped receiving section is designed in the relaxed state about 2.2 mm wide and that the connection between the central web and the upper web of the Z-shaped connecting section takes place via a bend resting on the free, resilient end of the receiving section and a second, opposite bend, which is smaller in size than the bend.

Eine weitere Ausführung der Erfindung besteht darin, daß der Spalt halb so breit ist wie der Abstand zwischen dem Anlagepunkt des oberen stegs an der Hinterschneidung und der Innenseite des freien Endes des Aufnahmeabschnitts.Another embodiment of the invention is that the gap is half as wide as the distance between the Point of contact of the upper web on the undercut and the inside of the free end of the Recording section.

Die mit der Erfindung erzielten Vorteile bestehen im wesentlichen darin, daß, im Gegensatz zu dem bekannten Rolladenkasten mit einer scharnierartigen Verbindung zwischen Oberteil und Unterteil, ein einfacheres und damit bequemeres Zusammenfügen von Unterteil und Oberteil möglich ist, wonach Ober- und Unterteil durch eine Art Klemmverbindung lösbar miteinander verbunden sind. Durch die verhältnismäßig einfache Konstruktion der Verbindung von Oberteil und Unterteil ergibt sich darüber hinaus ein kostengünstig herstellbarer Rolladenkasten und Ober- und Unterteil sind sicher miteinander verklemmt trotz kleinem Schwenkwinkel zum Lösen des Unterteils.The advantages achieved by the invention are essential in that, in contrast to the known Roller shutter box with a hinge-like connection between top and bottom, a simpler and thus more convenient joining of the lower part and upper part it is possible, according to which the upper and lower part by a kind Clamp connection are releasably connected. By the relatively simple construction of the connection the upper and lower part also result roller shutter box and upper and lower cost Lower part are securely clamped together despite the small Swivel angle for loosening the lower part.

In Fig. 1 ist mit 1 das Oberteil des Rolladenkastens bezeichnet und 2 ist das Unterteil. In dem dargestellten Ausführungsbeispiel besteht demnach der Rolladenkasten praktisch aus zwei rechtwinklig abgekanteten Blechen. In dem durch das Oberteil 1 und das Unterteil 2 eingeschlossenen Raum befindet sich, strichpunktiert angedeutet, die Tragrolle 8 für den Rolladen.In Fig. 1, 1 is the upper part of the roller shutter box designated and 2 is the lower part. In the illustrated Accordingly, the embodiment is the roller shutter box practically from two sheets bent at right angles. In the through the upper part 1 and the lower part 2 enclosed space is, dash-dotted indicated, the support roller 8 for the roller shutter.

Von besonderer Bedeutung ist die Verbindung von Ober- und Unterteil, was als Einzelheit A aus Fig. 1 in den Fig. 2 und 3 dargestellt ist, wobei Fig. 2 den Zustand zeigt, wo das Unterteil 2 in das Oberteil 1 eingesetzt wird, während Fig. 3 den fertig montierten Zustand zeigt, ebenso wie Fig. 6.The connection of top and bottom is of particular importance Lower part, which as detail A from FIG. 1 in FIG. 2 and 3 is shown, with FIG. 2 showing the state where the lower part 2 is inserted into the upper part 1, 3 shows the fully assembled state, as well as Fig. 6.

Fig. 2 entspricht der ausgeschwenkten, gestrichelt gezeichneten Stellung des Unterteils 2 in Fig. 1 und Fig. 3 eingeschwenkten, stark ausgezogen gezeichneten Stellung des Unterteils 2 in Fig. 1. Der Doppelpfeil 10 deutet die Schwenkbewegung des Unterteils 2 an. Fig. 2 corresponds to the swung out, dashed drawn position of the lower part 2 in Fig. 1 and Fig. 3 swung in, strongly drawn position of the lower part 2 in FIG. 1. The double arrow 10 indicates the pivoting movement of the lower part 2.

Das Oberteil 1 hat einen S-förmigen Aufnahmeabschnitt 3, dem ein Z-förmiger Verbindungsabschnitt 4 zugeordnet ist, der sich am Ende des Unterteils 2 befindet. Der S-förmige Aufnahmeabschnitt 3 weist eine Hinterschneidung 5 auf, die unter einem Winkel α gegen die Senkrechte von 10 - 40° verläuft. Dazu passend ist der obere Steg 6 des Z-förmigen Verbindungsabschnitts 4 unter einem Winkel gegen die Senkrechte von ebenfalls 10 bis 40° angeordnet. Die Winkel α und β sind im Normalfall gleich groß, beispielsweise sind α und β gleich 30°. So ergibt sich, wie die Fig. 1 und 3 zeigen, im montierten Zustand eine formschlüssige Verbindung zwischen Oberteil 1 und Unterteil 2: Der obere Steg 6 des Z-förmigen Verbindungsabschnitts 4 liegt einerseits an der Hinterschneidung 5 an und der Bogen 12 stützt sich andererseits am freien, federnd ausgebildeten Ende 9 des Aufnahmeabschnitts 3 ab. Der Spalt 11 an dem S-förmigen Aufnahmeabschnitt 3 ist im entspannten Zustand (Fig. 4) ca. 2,2 mm breit, was für gängige Materialstärken von Ober- und Unterteil gilt, d.h. Materialstärken von 0,88 bis 1,25 mm.The upper part 1 has an S-shaped receiving section 3, to which a Z-shaped connecting section 4 is assigned, which is located at the end of the lower part 2. The S-shaped receiving section 3 has an undercut 5, which extends at an angle α against the vertical of 10-40 °. To match, the upper web 6 of the Z-shaped connecting section 4 is arranged at an angle to the vertical of likewise 10 to 40 °. The angles α and β are normally the same size, for example α and β are 30 °. As shown in FIGS. 1 and 3, this results in a positive connection between the upper part 1 and lower part 2 in the assembled state: the upper web 6 of the Z-shaped connecting section 4 rests on the undercut 5 on the one hand and the arch 12 is supported on the other hand from the free, resilient end 9 of the receiving section 3. The gap 11 on the S-shaped receiving section 3 is about 2.2 mm wide in the relaxed state (FIG. 4), which applies to common material thicknesses of the upper and lower part, ie material thicknesses of 0.88 to 1.25 mm.

Von besonderer erfindungsgemäßer Bedeutung ist die Ausbildung des Übergangs von dem Mittelsteg 7 zu dem oberen Steg 6 des Z-förmigen Verbindungsabschnitts 4, was in Fig. 6 vergrößert dargestellt ist: Zwischen dem Mittelsteg 7 und dem oberen Steg 6 ist ein am freien, federnden Ende 9 des Aufnahmeabschnitts 3 anliegender Bogen 12 vorgesehen, dem ein zweiter, gegenläufiger Bogen 13 folgt, der in seiner Ausdehnung kleiner als der Bogen 12 ist. Durch diese Maßnahme ergibt sich im montierten Zustand (Fig. 6) eine absolut sichere Verklemmung zwischen dem Oberteil 1 und dem Unterteil 2. Ein weiterer Effekt dieser konstruktiven Maßnahme ist, daß der Spalt 17 zwischen Oberteil 1 und Unterteil 2 kleiner als bei bekannten Ausführungen ist, was technisch und optisch einer perfekteren Lösung gleichkommt.Of particular importance according to the invention is the Training the transition from the Mittelsteg 7 to the upper web 6 of the Z-shaped connecting section 4 what is shown enlarged in Fig. 6: Between the Mittelsteg 7 and the upper web 6 is an outdoor, resilient end 9 of the receiving section 3 adjacent Sheet 12 is provided, the second, opposite sheet 13 follows, the extent of which is smaller than the arc 12 is. This measure results in the assembled Condition (Fig. 6) an absolutely safe jamming between the upper part 1 and the lower part 2. Another The effect of this constructive measure is that the gap 17 between the upper part 1 and lower part 2 smaller than in known designs is what is technical and visual is a perfect solution.

Gegebenenfalls kann auch vorgesehen sein, daß eine federnde Verbindung von Oberteil und Unterteil 2 verwirklicht wird, indem der Winkel β größer als der Winkel α gewählt wird, um eine ausgeprägte Federwirkung zu erreichen.If necessary, it can also be provided that a resilient connection of the upper part and lower part 2 is achieved by selecting the angle β greater than the angle α in order to achieve a pronounced spring action.

Bei einer bevorzugten Ausführungsform (Fig. 6) ist der Spalt 11 halb so breit wie der Abstand 14 zwischen dem Anlagepunkt 15 und der Innenseite 16 des freien Endes 9 des Aufnahmeabschnitts 3; es hat sich bei Versuchen gezeigt, daß bei einer solchen Ausbildung eine optimale Verklemmung zwischen Oberteil 1 und Unterteil 2 vorhanden ist.In a preferred embodiment (Fig. 6) Gap 11 half as wide as the distance 14 between the Contact point 15 and the inside 16 of the free end 9 the receiving section 3; it has been tried shown that with such training an optimal There is jamming between the upper part 1 and lower part 2 is.
