Description

Die vorliegende Erfindung betrifft eine Lamelle, insbesondere zum Einbau in ein Lamellenregister zur Beschattung von Gebäuden, mit einem Lamellenprofil aus einem extrudierbaren ersten Werkstoff, beispielsweise Aluminium.The present invention relates to a slat, in particular for installation in a slat register for shading buildings, with a slat profile of an extrudable first material, such as aluminum.

Im Stand der Technik sind Lamellenprofile bekannt, die aus extrudiertem Werkstoff, wie beispielsweise Aluminium oder anderen metallischen Werkstoffen, bestehen. Diese Profile weisen im Querschnitt eine Trapezform oder Ellipsenform auf und sind in ihrem Inneren durch Querwandungen unterteilt und bilden somit ein Hohlprofil mit mehreren Kammern aus. Solche Lamellen werden für eine Farbgestaltung eloxiert oder farbbeschichtet, so dass diese Lamellen in unterschiedlichen Farben in einem Lamelleregister montiert werden können. Bei diesen Lamellenprofilen gibt es lediglich eine einfarbige Oberflächengestaltung. Es ist nicht möglich, die Oberfläche unabhängig von dem gewählten Werkstoff für eine besondere Reflexion oder Absorption von Licht zu gestalten oder andere Funktionen in die Oberfläche zu integrieren. Auch ist die farbliche Gestaltungsmöglichkeit begrenztIn the prior art lamellar profiles are known which consist of extruded material, such as aluminum or other metallic materials. These profiles have a trapezoidal shape or elliptical shape in cross-section and are divided in their interior by transverse walls and thus form a hollow profile with a plurality of chambers. Such slats are anodised or color-coated for a color design, so that these slats can be mounted in different colors in a lamella register. These lamella profiles have only a single-color surface design. It is not possible to make the surface independent of the material chosen for a particular reflection or absorption of light or to integrate other functions into the surface. Also, the color scheme is limited

Die DE 43 25 121 zeigt einen aus einzelnen Metallstäben gebildeten Panzer für Rollläden, Rolltore oder Jalousien, bei dem an einem Metallprofil an gegenüberliegenden Seiten Nuten ausgebildet sind in die Stege eines Halteprofils zur Abdeckung des Metallprofils eingreifen. Dadurch ist die Außenfläche des Metallstabs ein Blendprofil überdeckt. Gerade bei größeren Längen der Metallstäbe kann es jedoch passieren, dass der Metallstab sich bei einer Belastung quer zur Ebene des Blendprofils durchbiegt. Zudem können sich in den Nuten und Zwischenräumen zwischen Blendprofil und Metallstab Verunreinigungen ansammeln.The DE 43 25 121 shows a tank formed from individual metal bars for shutters, roller shutters or blinds, in which grooves are formed on a metal profile on opposite sides in the webs of a holding profile to cover the metal profile. As a result, the outer surface of the metal rod is covered by a blend profile. Especially with larger lengths of the metal rods, however, it may happen that the metal rod sags when loaded transversely to the plane of the blend profile. In addition, impurities can accumulate in the grooves and spaces between blend profile and metal rod.

Die DE 90 17 508 zeigt eine Lamelle einer Jalousie, bei der in eine Aufnahme ein Einsatz eingefügt werden kann, der die Gestaltung der Lamelle auf einfache Weise verändern kann. Der Einsatz ist dabei randseitig durch eine Leiste überdeckt, so dass aufgrund der gestuften Ausbildung sich Verunreinigungen ansammeln können die schlecht zu entfernen sind. Zudem ist die Lamelle nur plattenförmig ausgebildet und sich gerade bei größeren Längen ebenfalls durchbiegen.The DE 90 17 508 shows a slat of a blind, in which an insert can be inserted into a receptacle that can change the design of the slat in a simple manner. The insert is covered on the edge by a bar, so that due to the stepped training can accumulate impurities are difficult to remove. In addition, the lamella is only plate-shaped and also bend at larger lengths also.

Die WO 90/05602 zeigt eine aus mehreren Profilen ausgebildete Lamelle, die eine teilweise plattenfi5rmige Außenkontur aufweist, so dass bei einer bestimmten Stellung der Lamelle sich Flüssigkeit ansammeln kann. Ferner weist die Lamelle keine Aufnahmenut für Einsatzelemente auf.The WO 90/05602 shows a lamella formed from a plurality of profiles, which has a partially plate-shaped outer contour, so that at a certain position of the lamella liquid can accumulate. Furthermore, the lamella has no receiving groove for insert elements.

Es ist daher Aufgabe der vorliegenden Erfindung, eine Lamelle zu schaffen, deren Oberflächenstruktur an unterschiedliche Einsatzzwecke anpassbar ist.It is therefore an object of the present invention to provide a blade whose surface structure is adaptable to different purposes.

Diese Aufgabe wird mit einer Lamelle mit den Merkmalen des Anspruches 1 gelöst.This object is achieved with a blade with the features of claim 1.

Wenn an mindestens einer Seite des Lamellenprofils ein Einsatzelement aus einem anderen Werkstoff als dem Werkstoff des Lamellenprofils vorgesehen ist, kann die Oberflächenstruktur unabhängig vom gewählten Werkstoff für das Lamellenprofil gestaltet werden. Insbesondere kann die Oberfläche reflektierend ausgebildet sein, um einen Innenraum mit indirektem Licht zu durchfluten. Demgegenüber kann die Oberfläche auch absorbierend ausgebildet sein, um auftreffendes Licht nicht über Reflexion in den Innenraum gelangen zu lassen. Auch andere technische Funktionen, wie die Dämpfung von Niederschlägen auf die Lamellen können mit den Einsatzelementen realisiert werden.If an insert element made of a material other than the material of the lamellar profile is provided on at least one side of the lamellar profile, the surface structure can be designed independently of the selected material for the lamellar profile. In particular, the surface may be designed to be reflective in order to flood an interior space with indirect light. In contrast, the surface may also be designed to be absorbent in order to prevent incident light from reaching the interior via reflection. Other technical functions, such as the damping of rainfall on the slats can be realized with the insert elements.

Dabei ist das Einsatzelement plattenförmig ausgebildet und an die Außenkontur des Lamellenprofils angepasst. Dies ermöglicht ein besonders formschönes, gleichmä-ßiges Erscheinungsbild der Lamelle. Ferner ist das Einsatzelement in einer Aufnahmenut des Lamellenprofils aufgenommen. Unter Aufnahmenut wird dabei ein zurückgesetzter Bereich verstanden, in den das Einsatzelement eingepasst werden kann, so dass Randleisten des Lamellenprofils und die Außenfläche der Einsatzelemente eine glatte Außenkontur (Sollkontur) bilden.In this case, the insert element is plate-shaped and adapted to the outer contour of the lamella profile. This allows a particularly shapely, uniform appearance of the lamella. Furthermore, the insert element is received in a receiving groove of the lamellar profile. In this case, a recessed area is understood as the receiving groove, into which the insert element can be fitted so that edge strips of the lamella profile and the outer surface of the insert elements form a smooth outer contour (nominal contour).

Erfindungsgemäß ist das Lamellenprofil im Querschnitt im wesentlichen oval mit abgerundeten Außenflächen ausgebildet, wobei die Einsatzelemente eine der Au-Benfläche entsprechende Krümmung aufweisen. Dadurch wird verhindert, dass sich Regen- oder Kondenswasser an der Lamelle ansammeln kann.According to the invention the lamellar profile is formed in cross-section substantially oval with rounded outer surfaces, wherein the insert elements have a curvature corresponding to the Au Benfläche. This prevents rain or condensation from accumulating on the lamella.

Vorzugsweise ist an dem Lamellenprofil beidseitig jeweils ein Einsatzelement aus dem zweiten Werkstoff vorgesehen. Es ist auch möglich, verschiedene Einsatzelemente auf beiden Seiten des Lamellenprofils vorzusehen, um beispielsweise auf einer Seite die Absorption und auf der anderen Seite die Reflexion des eintreffenden Lichtes zu realisieren. Als Werkstoffe für die Einsatzelemente können Bleche verschiedener Metalle, Edelstahl, Glas, Keramik, Gummi, Kunststoff, Holz u.a. Materialien eingesetzt werden.Preferably, an insert element made of the second material is provided on both sides of the lamellar profile. It is also possible to provide different insert elements on both sides of the lamellar profile in order, for example, to realize the absorption on one side and the reflection of the incident light on the other side. As materials for the insert elements can sheets of various metals, stainless steel, glass, ceramic, rubber, plastic, wood u.a. Materials are used.

Um das Lamellenprofil in einem Lamellenregister montieren und bewegen zu können, ist dieses vorzugsweise als Hohlprofil mit einem Lagerkanal und mindestens einem Schraubkanal zur Festlegung einer Abdeckung ausgebildet. Mit der Abdeckung läßt sich das Einsatzelement in axialer Richtung fixieren. Das Einsatzelement kann dabei entweder in das Lamellenprofil eingeschoben werden und ist dann randseitig an dem Lamellenprofil gehalten, oder in das Lamellenprofil verrastet werden. Auch andere Befestigungsformen, wie Kleber, mechanische Verbindungsmittel, Schrauben oder Nieten können eingesetzt werden.In order to mount the lamellar profile in a lamellar register and move, this is preferably formed as a hollow profile with a bearing channel and at least one screw to define a cover. With the cover, the insert element can be fixed in the axial direction. The insert element can either be inserted into the lamella profile and is then held at the edge of the lamella profile, or locked in the lamella profile. Other forms of attachment, such as adhesives, mechanical fasteners, screws or rivets can be used.

Gemäß einer weiteren Ausführungsform der Erfindung sind auf einer Seite des Lamellenprofils zwei Einsatzelemente vorgesehen. Dies ermöglicht die gezielte Lichtumlenkung innerhalb eines Lamellenregisters, so dass bei einer halbgeöffneten Stellung das Licht mittels eines Einsatzelementes reflektiert wird, während bei einer geschlosseneren Stellung die Reflexion durch den Einsatz eines weiteren absorbierenden Einsatzelementes gedämpft wird. Um die beiden Einsatzelemente abgedichtet an dem Lamellenprofil zu verriegeln, ist vorzugsweise ein Keder aus Gummi zwischen den Einsatzelementen vorgesehen.According to a further embodiment of the invention, two insert elements are provided on one side of the fin profile. This allows the targeted light deflection within a lamellae register, so that in a half-open position, the light is reflected by an insert element, while in a closed position, the reflection is damped by the use of another absorbent insert element. In order to lock the two insert elements sealed on the slat profile, a rubber piping is preferably provided between the insert elements.

Gemäß einer weiteren Ausführungsform der Erfindung ist das Einsatzelement als fotovoltaisches Elemente ausgebildet, so dass mittels entsprechender Leitungen das Lamellenregister zur Stromerzeugung eingesetzt werden kann. Auch eine Wärmeabsorption durch die Lamellenoberfläche ist möglich.According to a further embodiment of the invention, the insert element is designed as a photovoltaic element, so that by means of appropriate lines, the fin register can be used to generate electricity. Also a heat absorption by the lamellar surface is possible.

Die in den Figuren 1 bis 4 dargestellte Lamelle 1 umfaßt ein Lamellenprofil 2, das als stranggepreßtes Hohlprofil aus Aluminium ausgebildet ist und im wesentlichen die Außenkontur der Lamelle 1 vorbestimmt. Das Lamellenprofil 2 besitzt an zwei gegenüberliegenden Enden Lamellenrandleisten 3, die randseitig die Außenkontur der Lamelle 1 vorgeben. Zwischen den Lamellenrandleisten 3 befindet sich an zwei gegenüberliegenden Seiten jeweils eine Aufnahmenut 4, deren Nutboden 5 sich zwischen den beiden Lamellenrandleisten 3 erstreckt. Als Aufnahmenut 4 wird dabei der zurückgesetzte Bereich zwischen den beiden Lamellenrandleisten 3 bezeichnet.The slat 1 shown in Figures 1 to 4 comprises a slat profile 2, which is formed as extruded hollow profile made of aluminum and substantially the outer contour of the slat 1 predetermined. The lamellar profile 2 has at two opposite ends lamellar edge strips 3, which define the outer contour of the lamella 1 at the edge. Between the slat edge strips 3 is located on two opposite sides in each case a receiving groove 4, the groove bottom 5 extends between the two slat edge strips 3. As a receiving groove 4 while the recessed area between the two slat edge strips 3 is referred to.

Die Aufnahmenut 4 dient zur Aufnahme eines plattenförmigen Einsatzelementes 10, dessen Dicke der Tiefe der Aufnahmenut 4 entspricht. Dementsprechend sind die Übergänge der Einsatzelemente 10 zu den Lamellenrandleisten 3 glatt ausgebildet.The receiving groove 4 serves to receive a plate-shaped insert element 10 whose thickness corresponds to the depth of the receiving groove 4. Accordingly, the transitions of the insert elements 10 to the slat edge strips 3 are smooth.

Zur Festlegung der Einsatzelemente ist an den Lamellenrandleisten ein Hinterschnitt 7 ausgebildet, welcher durch eine in die Aufnahmenut 4 hervorstehende Nutrandleiste 8 begrenzt wird. Das Einsatzelement 10 weist einen zurückgesetzten Vorsprung 11, der im montierten Zustand in den Hinterschnitt 7 eingreift. Je nach Werkstoff kann das Einsatzelement entweder gebogen werden und somit nach Art einer Rastverbindung an dem Lamellenprofil 2 festgelegt werden oder seitlich in das Lamellenprofil 2 eingeschoben werden.Laying down the insert elements, an undercut 7 is formed on the lamella edge strips, which is bounded by a groove groove 8 protruding into the receiving groove 4. The insert member 10 has a recessed projection 11 which engages in the undercut 7 in the mounted state. Depending on the material, the insert element can either be bent and thus according to Art a latching connection to be fixed to the slat profile 2 or laterally inserted into the slat profile 2.

In der Mitte des Lamellenprofils befindet sich ein Lagerkanal 100, der eine Drehachse für die Lamelle 1 bildet, so daß die Stellung der Lamelle 1 in einem Lamellenregister variiert werden kann. Im Bereich des Lagerkanals 100 ist eine hinterschnittene Nut 9 in dem Nutboden 5 vorgesehen. In diese Nut 9 können an dem Einsatzelement 10 angeordnete Fixierleisten 12 eingebracht werden, wobei zwischen den Fixierleisten 12 ein Kanal 13 ausgebildet ist. Bei der Montage der Einsatzelemente 10 kann eine Vorfixierung stattfinden, wenn das Einsatzelement 2 noch nicht durch einen Lamellendeckel gesichert ist. Hierbei wird ein Bolzen 16 in den Kanal 13 der Fixierleiste 12 eingetrieben, der sich zusätzlich am Nutgrund der Nut 9 abstützt. Der Bolzen 16 ist so bemessen, daß er die Fixierleiste 12 auseinandertreibt, so daß diese an den hinterschnittenen Nutwandungen der Nut 9 klemmend zur Anlage kommt.In the middle of the lamellar profile is a bearing channel 100 which forms an axis of rotation of the lamella 1, so that the position of the lamella 1 can be varied in a lamellae. In the region of the bearing channel 100, an undercut groove 9 is provided in the groove bottom 5. In this groove 9 arranged on the insert member 10 fixing strips 12 can be introduced, wherein between the fixing strips 12, a channel 13 is formed. When mounting the insert elements 10 may take place a prefixing when the insert element 2 is not yet secured by a blade cover. In this case, a bolt 16 is driven into the channel 13 of the fixing strip 12, which is additionally supported on the groove bottom of the groove 9. The bolt 16 is dimensioned so that it disengages the fixing strip 12 so that it comes to rest on the undercut Nutwandungen the groove 9 by clamping.

Wie insbesondere aus Figur 1 ersichtlich ist, wird das Lamellenprofil 2 beidseitig mit einem Einsatzelement 10 bestückt, das mittels Bolzen 16 in der beschriebenen Weise vorfixiert wird. Am Stirnende des Lamellenprofils 2 wird anschließend ein Lagerschild 23 mittels Schrauben 25 befestigt, die in Schraubkanäle 14, 15 in dem Lamellenprofil 2 eingedreht werden. Das Lagerschild 23 besitzt einen Ausleger 27, der endseitig ein Lagerauge 26 besitzt, das eine Anlenkachse für einen Beschlag zur Schwenkbetätigung der Lamelle 1 bildet. Durch den Lagerschild 23 kann der Anlenkpunkt bzw. die Anlenkachse des Stellbeschlages variiert werden. Durch diese Maßnahme kann der Weg des Beschlages zur Lenkung der Lamelle optimiert werden. Der Verstellhub des Verstellbeschlages kann durch Heranrücken der Anlenkachse an eine Schwenkachse der Lamelle 1 verringert werden. Die Schwenkachse ist durch einen Lagerbolzen 21 gebildet, der in den Lagerkanal 100 eingetrieben ist und mittels eines Ringes 30 in axialer Richtung fixiert ist.As can be seen in particular from FIG. 1, the lamellar profile 2 is equipped on both sides with an insert element 10 which is prefixed by means of bolts 16 in the manner described. At the front end of the slat profile 2, a bearing plate 23 is then fastened by means of screws 25 which are screwed into screw channels 14, 15 in the slat profile 2. The bearing plate 23 has a boom 27, the end has a bearing eye 26 which forms a pivot axis for fitting for pivotal actuation of the blade 1. By the end plate 23, the articulation point or the pivot axis of the adjusting fitting can be varied. By this measure, the way the fitting for steering the slat can be optimized. The adjustment stroke of the adjustment fitting can be reduced by approaching the pivot axis to a pivot axis of the slat 1. The pivot axis is formed by a bearing pin 21 which is driven into the bearing channel 100 and is fixed by means of a ring 30 in the axial direction.

In die Anlenkachse 26 ist eine Hülse 28 zur Lagerung eines nicht dargestellten Bolzens eingefügt.In the pivot axis 26, a sleeve 28 is inserted for supporting a bolt, not shown.

Auf der gegenüberliegenden Seite ist ein Achsbolzen 22 in den Lagerkanal 100 eingefügt, der durch einen Ring 30 in axialer Richtung fixiert ist. Zur Festlegung der Einsatzelemente 10 ist ein Lagerschild 24 mittels Schrauben 25 an dem Lamellenprofil 2 gehalten, wobei die Schrauben 25 in die entsprechenden Schraubkanäle 14 und 15 eingedreht sind.On the opposite side, a pivot pin 22 is inserted into the bearing channel 100, which is fixed by a ring 30 in the axial direction. Laying down the insert elements 10, a bearing plate 24 is held by means of screws 25 on the blade profile 2, wherein the screws 25 are screwed into the corresponding screw 14 and 15.

In Figur 5A ist ein zweites Ausführungsbeispiel einer erfindungsgemäßen Lamelle gezeigt. Das Lamellenprofil 2 entspricht dem Lamellenprofil des ersten Ausführungsbeispiels, so daß die gleichen Bezugszeichen für die entsprechenden Abschnitte verwendet wurden. Wie in Figur 5B zu sehen ist, wurde bei diesem Ausführungsbeispiel ein plattenförmiges Einsatzelement 6 verwendet, das an seinen beiden Enden 60 biegbar ausgestaltet ist und so in den Hinterschnitt 7 des Lamellenprofils 2 eingefügt werden kann. Eine mittige Befestigung an der Aufnahmenut 9 ist bei diesem Ausführungsbeispiel nicht vorgesehen.FIG. 5A shows a second embodiment of a lamella according to the invention. The fin profile 2 corresponds to the fin profile of the first embodiment, so that the same reference numerals have been used for the corresponding sections. As can be seen in Figure 5B, a plate-shaped insert element 6 was used in this embodiment, which is designed to be bendable at its two ends 60 and can be inserted into the undercut 7 of the lamellar profile 2. A central attachment to the receiving groove 9 is not provided in this embodiment.

In den beiden Kammern benachbart zu dem Lagerkanal 100 sind jeweils Versteifungselemente 101 einfügbar, die es ermöglichen, daß das sich über mehrere Meter erstreckende Lamellenprofil 2 statisch verstärkt wird.In the two chambers adjacent to the bearing channel 100 each stiffening elements 101 can be inserted, which make it possible that the extending over several meters slat profile 2 is statically reinforced.

In den Figuren 6 und 7 ist ein drittes Ausführungsbeispiel einer Lamelle dargestellt. Das Lamellenprofil 2 ist wie bei den vorangegangenen Ausführungsbeispielen ausgebildet.In the figures 6 and 7, a third embodiment of a blade is shown. The slat profile 2 is formed as in the previous embodiments.

An dem Lamellenprofil 2 sind beidseitig jeweils zwei Einsatzelemente 17 vorgesehen. Dieses Einsatzelement 17 weist eine Randkante 35 auf, die der Form des Hinterschnittes 7 des Lamellenprofils 2 entspricht. Eine Kante 26 an der Randkante 35 dient dabei als Anschlag und liegt an der Nutrandleiste 8 an. An der gegenüberliegenden Seite des Einsatzelementes 17 befindet sich ein Steg 18, der in die Nut 9 im Nutgrund der Aufnahmenut 4 eingreift und den Hinterschnitt dieser Nut 9 untergreift. Da beide Hinterschnitte der Nut 9 bzw. des Hinterschnittes 7 gleichgerichtet sind, kann das Einsatzelement 17 von oben in das Lamellenprofil 2 bzw. dessen Aufnahmenut 4 eingesetzt werden. Zwischen den montierten Einsatzelementen 17 bildet sich ein längs verlaufender Spalt 19 aus, in den ein Keder 20 eintreibbar ist. Dieser Keder 20 kann aus Metall, Kunststoff, insbesondere aber aus Gummi bestehen. Im Spalte 19 sind durch entsprechende Profilierungen der Einsatzelemente 17 Hinterschnitte ausgebildet, an denen sich der entsprechend geformte bzw. profilierte Keder 20 verrasten kann. Durch den Keder 20 ist die Lage der Einsatzelemente 17 vorfixiert und dauerhaft gesichert. Auch bei diesem Ausführungsbeispiel wird durch entsprechende Enddeckel bzw. Lageschilder die Lamelle verschlossen und die Einsatzelemente 17 gesichert.At the fin profile 2 two insert elements 17 are provided on both sides. This insert element 17 has a peripheral edge 35 which corresponds to the shape of the undercut 7 of the lamellar profile 2. An edge 26 on the peripheral edge 35 serves as a stop and is located on the Nutrandleiste 8. On the opposite side of the insert element 17 is a web 18 which engages in the groove 9 in the groove bottom of the receiving groove 4 and engages under the undercut of this groove 9. Since both undercuts of the groove 9 and the undercut 7 are rectified, the insert element 17 from above into the slat profile 2 and dessen Receiving groove 4 are used. Between the assembled insert elements 17, a longitudinally extending gap 19 is formed, into which a piping 20 can be driven. This piping 20 may be made of metal, plastic, but especially rubber. In the column 19, 17 undercuts are formed by appropriate profiling of the insert elements to which the correspondingly shaped or profiled piping 20 can lock. By the piping 20, the position of the insert elements 17 is pre-fixed and permanently secured. Also in this embodiment, the blade is closed by appropriate end cover or position plates and secured the insert elements 17.

Bei den vorgenannten Ausführungsbeispielen besteht zwischen den Einsatzelementen 6, 10 und 17 und dem Nutboden 5 ein kleiner Spalt, so daß die Einsatzelemente 6, 10 und 17 eine Dämpfungswirkung, beispielsweise gegenüber von außen auftreffenden Niederschlag besitzen. Dämpfung wird vor allem dann erzielt, wenn als Material für die Einsatzelemente dämpfende Werkstoffe, wie Gummi, Holz oder Kunststoff in vorzugsweise geschäumter Form, oder Kombinationen der Werkstoffe eingesetzt werden. Die Einsatzelemente 6, 10, 17 können eine Oberflächenstruktur mit reflektierender, absorbierender oder anderweitig profilierter Oberfläche besitzen, um gewünschte optische Effekte zu erreichen. Für sämtliche Lamellentypen kann ein Lamellenprofil 2 eingesetzt werden.In the aforementioned embodiments, there is a small gap between the insert elements 6, 10 and 17 and the groove bottom 5, so that the insert elements 6, 10 and 17 have a damping effect, for example against rainfall incident from the outside. Damping is achieved especially when used as material for the insert elements damping materials such as rubber, wood or plastic in preferably foamed form, or combinations of materials. The insert elements 6, 10, 17 may have a surface structure with a reflective, absorbent or otherwise profiled surface to achieve desired optical effects. For all types of slats a slat profile 2 can be used.

Es ist auch möglich, die Flächen der Lamellen 1 mit einer Reihe nebeneinander liegender Nuten aufzuteilen, um mittels einzelner nebeneinander liegender Einsatzelemente die Optik und auch die Funktion der Flächen dieser Lamellen partiell unterschiedlich zu gestalten.It is also possible to divide the surfaces of the slats 1 with a series of juxtaposed grooves in order to make partially different by means of individual juxtaposed insert elements, the appearance and the function of the surfaces of these slats.
