Abstract

A strip-shaped louvre having two lateral reflectors and a plurality of transverse strips, having V-shaped extending limbs, arranged therebetween. In known louvres of this type, the end edges of the transverse strips have a shape which corresponds to the shape of the lateral reflectors. The connection of lateral reflectors and transverse strips is served by bending lugs projecting therefrom, which are plugged through slots in the lateral reflectors and are bent round behind the latter. It is the object of the invention to simplify this complicated mode of installation. According to the invention, this is achieved by a combination of spring lugs (314, 316) in the transverse strips (3) and stops (312, 12) in the lateral reflectors (1, 2) in accordance with the main claim, the result being that the installation is reduced to a simple plugging together.

Description

Die Erfindung betrifft ein Lamellenraster mit zwei Seitenreflektoren und mehreren zwischen diesen angeordneten Querlamellen mit V-förmig verlaufenden Schenkeln, die an ihren Enden aufeinander zu gerichtete Randstreifen aufweisen, wobei die Seitenreflektoren der Kontur der Querlamellen entsprechende Durchbrüche haben, durch die die Querlamellen gesteckt sind.The invention relates to a lamella grid with two side reflectors and a plurality of transverse lamellae arranged between them with V-shaped legs which have edge strips directed towards one another at their ends, the side reflectors having openings corresponding to the contour of the transverse lamellae through which the transverse lamellae are inserted.

Bei einem aus der US-PS 3 777 432 bekannten Lamellenraster weisen die Endkanten der Querlamellen den gleichen Verlauf wie die Seitenreflektoren auf. Zur Verbindung dienen Biegelappen, die von den Enden der Querlamellen abstehen und die durch entsprechende Aussparungen in den Seitenreflektoren gesteckt und hinter diesen umgebogen werden müssen.In a lamella grid known from US Pat. No. 3,777,432, the end edges of the transverse lamellae have the same course as the side reflectors. Bending tabs are used for the connection, which protrude from the ends of the transverse slats and which have to be inserted through corresponding recesses in the side reflectors and bent behind them.

Der Erfindung liegt die Aufgabe zugrunde, diese in der Montage verhältnismäßig aufwendige Konzeption zu vereinfachen.The invention has for its object to simplify this relatively complex design in assembly.

Die erfindungsgemäße Lösung dieser Aufgabe ist bei einem Lamellenraster der eingangs genannten Art dadurch gekennzeichnet, daß zwischen einem schmalen Abschnitt des Randstreifens im Endbereich jeder Querlamelle und einem breiteren Abschnitt des Randstreifens zwischen den Seitenreflektoren jeweils eine Stufe liegt, daß in die Durchbrüche der Seitenreflektoren von oben mittig jeweils eine Zunge hineinragt, deren Breite so bemessen ist, daß die Schenkel der Querlamellen durch die an den Kanten der Zunge anliegenden schmalen Abschnitte ihres Randstreifens fest gegen den Rand des Durchbruches gedrückt werden, daß im Endbereich jedes Schenkels einer Querlamelle wenigstens ein mit seinem freien Ende dem gegenüberliegenden Endbereich der Querlamelle zugewandter Federlappen nach außen absteht, der so angeordnet ist, daß er auf der Rückseite des Seitenreflektors aufliegt und diesen dabei einerseits mit seiner Zunge gegen die Stufe im Randstreifen der Querlamelle und andererseits mit einem Profilrand gegen die Endkante der Querlamelle drückt.The inventive solution to this problem is characterized in a lamella grid of the type mentioned in that between a narrow section of the edge strip in the end region of each transverse lamella and a wider section of the edge strip between the side reflectors there is a step that in the openings of the side reflectors in the center from above A tongue protrudes in each case, the width of which is dimensioned such that the legs of the transverse lamellae are pressed firmly against the edge of the opening by the narrow sections of their edge strip lying against the edges of the tongue, such that at least one with its free end in the end region of each leg of a transverse lamella the opposite end region of the transverse lamella facing spring tab projects outwards, which is arranged so that it rests on the back of the side reflector and this on the one hand with its tongue against the step in the edge strip of the transverse lamella and on the other hand with a profile edge presses against the end edge of the cross lamella.

Die Montage eines erfindungsgemäßen Lamellenrasters reduziert sich.auf ein einfaches Zusammenstecken von Querlamellen und Seitenreflektoren.The assembly of a lamella grid according to the invention is reduced to a simple plugging together of transverse lamellae and side reflectors.

Die Erfindung wird anhand eines in den Figuren dargestellten Ausführungsbeispieles näher erläutert; es zeigen

  • Fig. 1 einen Querschnitt durch einen Teil eines Lamellenrasters,
  • Fig. 2 einen Schnitt entlang Linie II-II in Fig. 1 über einen Teil der Länge des Rasters (Seitenansicht),
  • Fig. 3 einen Teilschnitt entlang Linie III-III in Fig.1 in etwas vergrößerter Darstellung, und
  • Fig. 4 einen Teilschnitt entlng Linie IV-IV in Fig. 1 in vergrößerter Darstellung.
The invention is explained in more detail using an exemplary embodiment shown in the figures; show it
  • 1 shows a cross section through part of a lamella grid,
  • 2 shows a section along line II-II in FIG. 1 over part of the length of the grid (side view),
  • Fig. 3 is a partial section along line III-III in Fig.1 in a somewhat enlarged view, and
  • Fig. 4 is a partial section along line IV-IV in Fig. 1 in an enlarged view.

Zwischen den unterschiedlich gekrümmten Seitenreflektoren 1 und 2 eines Lamellenrasters verlaufen mehrere Querlamellen 3 mit jeweils V-förmigem Querschnitt. Jeder Seitenreflektor hat unten einen nach oben offenen, U-förmigen Profilrand 12. Die Seitenreflektoren 1, 2.weisen Durchbrüche 11 zum Durchstecken der Querlamellen 3 auf; die Kontur dieser Durchbrüche entspricht dem gewünschten Verlauf der Schenkel 31 der Querlamellen. In Fig. 2 ist einer dieser Durchbrüche 11 mit eingesteckter Querlamelle 31 und einer ohne Querlamelle dargestellt. In jeden solchen Durchbruch 11 ragt mittig von oben eine Zunge 111.Between the differently curved side reflectors 1 and 2 of a lamella grid, several transverse lamellae 3 each have a V-shaped cross section. Each side reflector has a U-shaped profile edge 12 which is open at the bottom. The side reflectors 1, 2 have openings 11 for inserting the transverse slats 3; the contour of these openings corresponds to the desired course of the legs 31 of the transverse lamellae. In Fig. 2, one of these openings 11 is shown with inserted cross plate 31 and one without cross plate. A tongue 111 projects centrally from above into each such opening 11.

Jede Querlamelle 3 hat zwei Schenkel 31, die an ihrem Ende aufeinander zu gerichtete Randstreifen aufweisen; diese Randstreifen haben im Bereich zwischen den Seitenreflektoren 1 und 2 einen breiten Abschnitt 312 und ausserhalb der Seitenreflektoren einen schmalen Abschnitt 311. Zwischen diesen Abschnitten liegt jeweils eine Stufe 313 (Fig. 3). Von dem schmalen Abschnitt 311 bis zu der Endkante 30 der Querlamelle verjüngt sich die Breite des Randstreifens stetig, wodurch das Zusammenstecken erleichtert wird.Each transverse lamella 3 has two legs 31 which have edge strips directed towards one another at their end; these edge strips have a wide section 312 in the area between the side reflectors 1 and 2 and a narrow section 311 outside the side reflectors. A step 313 lies between each of these sections (FIG. 3). From the narrow section 311 to the end edge 30 of the transverse lamella, the width of the edge strip tapers continuously, which makes it easier to plug it together.

Die schmalen Abschnitte 311 stützen sich gegen die Kanten der Zungen 111 ab, deren Breite so bemessen ist, daß die Schenkel 31 der Querlamellen 3 durch diese Zungen fest gegen die Kanten des Durchbruches 11 gedrückt werden (Fig. 2).The narrow sections 311 are supported against the edges of the tongues 111, the width of which is dimensioned such that the legs 31 of the transverse slats 3 are pressed firmly against the edges of the opening 11 by these tongues (FIG. 2).

Aus dem Endbereich jedes Schenkels 31 einer Querlamelle 3 sind im Abstand voneinander jeweils zwei Federlappen 314, 316, 315 und 317 herausgebogen, und zwar so, daß die freien Enden dieser Lappen jeweils auf den gegenüberliegenden Endbereich der Querlamelle gerichtet sind. Diese Federlappen stehen aus der Ebene der Schenkel der Querlamellen etwa um die Materialstärke dieser Schenkel heraus (Fig. 4). Die Lage dieser Federlappen ist so gewählt und der jeweils gewünschten Kontur des Seitenreflektors angepaßt, daß sie auf der Rückseite jedes Seitenreflektors aufliegen und diesen gegen Anschläge drükken, die einerseits von den Stufen 313 in den Randstreifen und andererseits von den Endkanten 30 der Querlamellen 3 gebildet werden. Insbesondere halten die unteren Federlappen 316, 317 das Randprofil 12 des Seitenreflektors 1 gegen die Endkante 30 und die oberen Federlappen 314, 315 die Zunge 111 gegen die Stufe 313 (Fig. 3).Two spring tabs 314, 316, 315 and 317 are bent out from the end region of each leg 31 of a transverse lamella 3 at a distance from one another, in such a way that the free ends of these lobes are each directed towards the opposite end region of the transverse lamella. These spring tabs stand out from the plane of the legs of the transverse lamellae about the material thickness of these legs out (Fig. 4). The position of these spring tabs is chosen and adapted to the desired contour of the side reflector in such a way that they rest on the back of each side reflector and press them against stops which are formed on the one hand by the steps 313 in the edge strips and on the other hand by the end edges 30 of the transverse slats 3 . In particular, the lower spring tabs 316, 317 hold the edge profile 12 of the side reflector 1 against the end edge 30 and the upper spring tabs 314, 315 hold the tongue 111 against the step 313 (FIG. 3).

Sofern die unteren Federlappen in einem Bereich liegen, in dem der Schenkel der Querlamelle praktisch nicht mehr elastisch ist, beim Zusammenstecken daher nicht mehr nachgibt, ist für eine ausreichende Federeigenschaft dieser Federungen selbst zu sorgen, z.B. durch einen kleinen Spalt entlang der Schnittkante.If the lower spring tabs are in an area in which the limb of the transverse lamella is practically no longer elastic and therefore no longer yields when plugged together, it is necessary to ensure that these springs have sufficient spring properties themselves, e.g. through a small gap along the cutting edge.

Bei der Montage werden die Querlamellen einfach in die Durchbrüche 11 eingesteckt, bis sie mit ihren Endkanten 30 gegen den Profilrand 12 anschlagen; beim Durchstecken werden die Schenkel 31 der Querlamellen durch die Federlappen zunächst etwas nach innen gedrückt; in der Endstellung federn sie jedoch zurück und die Federlappen verhaken sich hinter der Rückseite der Seitenreflektoren. Das Einstecken der Querlamellen in die Durchbrüche 11 wird durch die stetige Abnahme der Breite der Randstreifen im Randbereich der Querlamellen erleichtert (Fig. 3).During assembly, the transverse slats are simply inserted into the openings 11 until their end edges 30 strike the profile edge 12; when inserting, the legs 31 of the transverse lamellae are initially pressed somewhat inwards by the spring tabs; in the end position, however, they spring back and the spring tabs get caught behind the back of the side reflectors. The insertion of the transverse slats into the openings 11 is facilitated by the constant decrease in the width of the edge strips in the edge area of the transverse slats (FIG. 3).

Unter der Bezeichnung "V-förmiger Querschnitt" ist jede zweischenkelige Anordnung zu verstehen, bei der der Abstand zwischen den Schenkeln im Bereich der oberen freien Schenkelenden größer ist als im Verbindungsbereich der Schenkel.The term “V-shaped cross section” is to be understood as any two-leg arrangement in which the distance between the legs is greater in the area of the upper free leg ends than in the connecting area of the legs.
