Description

Die Erfindung betrifft eine Sonnenschutzeinrichtung gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a sun protection device according to the preamble of claim 1.

Eine derartige Sonnenschutzeinrichtung ist aus der EP 2 607 602 A1 bekannt. Diese Sonnenschutzeinrichtung umfasst einen auf einer Welle aufrollbaren Sonnenschutzbehang. Der Sonnenschutzbehang besteht aus einer Anordnung von in Aufrollrichtung hintereinander, über Gelenkverbindungen verbundene Lamellen, die jeweils eine Mehrfachanordnung von Lamellensegmenten aufweisen und in sich steif ausgebildet sind, so dass diese bei Aufrollen auf der Welle ihre Form beibehalten. Dasselbe gilt in entsprechender Weise für das Abrollen des Sonnenschutzbehangs von der Welle.Such sun protection device is from the EP 2 607 602 A1 known. This sun protection device comprises a rollable on a shaft sunshade. The Sonnenschutzbehang consists of an arrangement of in the winding direction one behind the other, connected via joints slats, each having a multiple arrangement of lamellar segments and are rigid in itself, so that they retain their shape when rolled on the shaft. The same applies in a similar manner for the unwinding of Sonnenschutzbehangs of the shaft.

Die einzelnen Lamellensegmente sind durch Einschub so miteinander verbunden, dass die optische Ansicht von außen sehr homogen wirkt, das heißt die Verbindung der einzelnen Lamellensegmente ist nicht sichtbar.The individual slat segments are interconnected by insertion so that the optical view from the outside looks very homogeneous, that is, the connection of the individual slat segments is not visible.

Der Sonnenschutzbehang ist so strukturiert, dass allein die Gelenkverbindungen zwischen den einzelnen Lamellen beweglich sind und so für die notwendige Formanpassung des Sonnenschutzbehangs bei einem Auf- oder Abrollen an der Welle sorgen. Die einzelnen Lamellen sind dagegen in sich steif ausgebildet und somit formstabil, das heißt diese biegen sich bei einem Auf- oder Abrollvorgang nicht auf. Durch diese Formstabilität der Lamellen weisen diese eine hohe Eigenstabilität auf.The Sonnenschutzbehang is structured so that only the joints between the individual slats are movable and so provide the necessary shape adaptation of the Sonnenschutzbehangs in a rolling up or rolling on the shaft. The individual slats, however, are inherently stiff and thus dimensionally stable, that is, these do not bend during a winding or unwinding. Due to this dimensional stability of the slats, these have a high intrinsic stability.

Zur Herstellung einer Gelenkverbindung zwischen zwei Lamellen einer derartigen Sonnenschutzeinrichtung weist typischerweise eine erste Lamelle ein erstes Gelenkelement auf, das in ein hierzu komplementäres Gelenkelement einer zweiten Lamelle eingeschoben wird. Die einzelne Lamelle ist so konstruiert, dass der Behang vorne und hinten abgerollt werden kann.To produce a joint connection between two lamellae of such a sunshade device, a first lamella typically has a first joint element, which in a complementary thereto hinge element a second blade is inserted. The single lamella is constructed in such a way that the curtain can be unrolled in front and behind.

Nach Einschieben der Gelenkelemente müssen diese gegen weitere horizontale Verschiebungen lagegesichert werden. Bei bekannten Sonnenschutzeinrichtungen erfolgt diese Lagesicherung dadurch, dass Verschlussteile an den längsseitigen Hohlräumen der Lamellen seitlich eingepresst oder eingeschlagen werden. Diese Art der Lagesicherung ist relativ einfach herzustellen und üblich.After inserting the joint elements, these must be secured in position against further horizontal displacements. In known sun protection devices, this position assurance takes place in that closure parts are pressed or impacted laterally against the longitudinal cavities of the lamellae. This type of position assurance is relatively easy to manufacture and common.

Das Vorsehen derartiger Verschlussteile ist jedoch dann problematisch, wenn es sich um Lamellen handelt ohne Hohlräume.The provision of such closure parts, however, is problematic when it comes to fins without cavities.

Die DE 87 02 763 U1 betrifft einen Rollladen, bestehend aus zusammengesteckten Profilstäben, die gegen Längsverschiebung gesichert sind. Die Verschiebesicherung erfolgt durch seitliche Nocken und Ausnehmungen.The DE 87 02 763 U1 relates to a roller shutter, consisting of assembled profile bars, which are secured against longitudinal displacement. The displacement protection is carried out by lateral cams and recesses.

Der Erfindung liegt die Aufgabe zugrunde, für eine Sonnenschutzeinrichtung der eingangs genannten Art eine Verriegelung bereitzustellen, welche bei geringem konstruktiven Aufwand eine hohe Mehrfach Funktionalität aufweist.The invention has for its object to provide a lock for a sun protection device of the type mentioned, which has a high multiple functionality with low design cost.

Zur Lösung dieser Aufgabe sind die Merkmale des Anspruchs 1 vorgesehen. Vorteilhafte Ausgestaltungen und zweckmäßige Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben.To solve this problem, the features of claim 1 are provided. Advantageous embodiments and expedient developments of the invention are described in the subclaims.

Die erfindungsgemäße Sonnenschutzeinrichtung umfasst einen auf einer Welle aufrollbaren Sonnenschutzbehang. Der Sonnenschutzbehang besteht aus einer Anordnung von in Aufrollrichtung hintereinander, über Gelenkverbindungen verbundene Lamellen, welche jeweils eine Mehrfach-Anordnung von Lamellensegmenten aufweisen. Benachbarte Lamellen sind gegen seitliche Verschiebungen durch Verriegelungsteile lagegesichert, welche in Aussparungen in den Lamellen an deren Ober- oder Unterseiten eingerastet sind.The sun protection device according to the invention comprises a sunshade curtain which can be rolled up on a shaft. The Sonnenschutzbehang consists of an arrangement of rolling in the succession, connected via joints lamellae, which each have a multiple arrangement of lamellar segments. Adjacent lamellae are positionally secured against lateral displacements by locking parts which are latched into recesses in the lamellae at their upper or lower sides.

Ein wesentlicher Vorteil der Erfindung besteht darin, dass durch das Einrasten der Verriegelungsteile in die Aussparungen der Lamellen sehr einfach und schnell Lagesicherungen für die einzelnen Lamellen bereitgestellt werden. Der Sonnenschutzbehang kann damit schnell und einfach hergestellt beziehungsweise montiert werden. Besonders vorteilhaft ist, dass die Aussparungen an
den Oberseiten oder Unterseiten der Lamellen liegen, was ein besonders einfaches und komfortables Einrasten der Verriegelungsteile in diesen Aussparungen ermöglicht, indem diese Verriegelungsteile von oben oder unten in die Lamellen eingerastet werden.A significant advantage of the invention is that by locking the locking parts in the recesses of the slats very easy and quick position backups for individual slats are provided. The Sonnenschutzbehang can thus be quickly and easily manufactured or mounted. It is particularly advantageous that the recesses
the tops or undersides of the slats, which allows a particularly simple and comfortable locking of the locking parts in these recesses by these locking parts are snapped into the slats from above or below.

Zweckmäßigerweise sind an beiden längsseitigen Rändern der Lamellen Verriegelungsteile vorgesehen.Conveniently, locking parts are provided on both longitudinal edges of the slats.

Dadurch werden die Lamellen gegen ein gegenseitiges Verschieben vollständig gesichert.As a result, the slats are completely secured against mutual displacement.

Die hierzu verwendeten Verriegelungsteile bestehen aus Kunststoff im Gegensatz zu den Lamellen, die aus metallischen Werkstoffen wie Aluminium oder Edelstahl bestehen.The locking parts used for this purpose are made of plastic in contrast to the slats, which consist of metallic materials such as aluminum or stainless steel.

Die Verriegelungsteile bestehen vorzugsweise jeweils aus einem einzigen Kunststoff-Spritzgussteil, welches kostengünstig herstellbar ist. Besonders vorteilhaft sind alle Verriegelungsteile der Sonnenschutzeinrichtung identisch ausgebildet, wodurch diese Verriegelungsteile besonders rationell gefertigt werden können, da keine unterschiedlichen Varianten benötigt werden.The locking parts preferably each consist of a single plastic injection-molded part, which is inexpensive to produce. Particularly advantageously, all locking parts of the sun protection device are formed identically, whereby these locking parts can be made very efficient, since no different variants are needed.

Ein besonderer Vorteil der Erfindung besteht darin, dass mit den Verriegelungsteilen nicht nur eine Lagesicherung jeweils zweier gelenkig verbundenen Lamellen erzielt wird. Vielmehr erfüllen diese auch Schutzfunktionen für den gesamten Sonnenschutzbehang. Diese Schutzfunktion wird dadurch erfüllt, dass die Verriegelungsteile, die aus relativ weichem und damit nachgiebigem Material bestehen, die metallischen Lamellen gegen einen Kontakt mit ebenfalls metallischen Körpern bewahren und so die Lamellen vor Beschädigungen schützen.A particular advantage of the invention is that with the locking parts not only a position assurance each two hingedly connected slats is achieved. Rather, these also fulfill protective functions for the entire sunshade. This protective function is fulfilled by the fact that the locking parts, which are made of relatively soft and therefore yielding material, the metallic lamellae to prevent contact also with metallic bodies and thus protect the slats from damage.

Besonders vorteilhaft stehen Segmente der Verriegelungsteile seitlich über die längsseitigen Ränder der Lamellen hervor und bilden dadurch Anschlagflächen.Particularly advantageous segments of the locking members project laterally beyond the longitudinal edges of the slats and thereby form stop surfaces.

Damit wird auf konstruktiv einfache Weise verhindert, dass die Lamellen bei Auf- oder Abrollen auf der Welle seitlich in Kontakt mit einer Schiene oder einer sonstigen Führung kommen, was zu Beschädigungen der Lamellen führen könnte. Vielmehr kommen nur die seitlich über die Lamellen überstehenden Segmente der Verriegelungsteile in Kontakt mit der Schiene und schützen so die Lamellen gegen ein Anstoßen an die Schienen.This prevents in a structurally simple manner that the slats come laterally when rolling or rolling on the shaft in contact with a rail or other guide, which could lead to damage of the slats. On the contrary, only the segments of the locking parts projecting laterally beyond the slats come into contact with the rail and thus protect the slats against being hit against the rails.

Weiterhin vorteilhaft stehen Segmente der Verriegelungsteile über die Oberseiten oder Unterseiten der Lamellen hervor und bilden dadurch Schutzelemente bei Auf- oder Abrollen der Lamellen.Further advantageously, segments of the locking parts protrude beyond the upper sides or lower sides of the slats and thereby form protective elements when the slats are rolled up or unrolled.

Die nach oben und/oder über die Lamellen hervorstehenden Segmente verhindern, dass die Lamellen bei Auf- oder Abrollen miteinander dicht in Kontakt kommen und verhindern so Beschädigungen der Lamellen.The segments projecting upwards and / or over the lamellae prevent the lamellae from coming into tight contact with one another during winding or unrolling and thus prevent damage to the lamellae.

Besonders vorteilhaft sind alle Verriegelungsteile identisch ausgebildet, so dass nur ein Typ eines Verriegelungsteils für die gesamte Sonnenschutzeinrichtung benötigt wird. Dies ermöglicht einerseits eine rationelle Herstellung der Verriegelungsteile und vereinfacht zudem die Montage der Sonnenschutzeinrichtung, da nicht unterschiedliche Verriegelungsteile in bestimmten, unterschiedlichen Einbaupositionen montiert werden müssen.Particularly advantageously, all locking parts are identical, so that only one type of locking part for the entire sun protection device is needed. This allows on the one hand a rational production of the locking parts and also simplifies the installation of the sunshade, since not different locking parts must be mounted in certain, different mounting positions.

Gemäß einer besonders vorteilhaften konstruktiven Ausgestaltung weist jedes Verriegelungsteil ein Kopfstück auf, welches im Bereich einer Gelenkverbindung zwischen zwei Lamellen angeordnet ist und mittels dessen eine Lagesicherung zweier benachbarter Lamellen erhalten wird.According to a particularly advantageous structural design, each locking part has a head piece, which is arranged in the region of a hinge connection between two slats and by means of which a positional securing of two adjacent slats is obtained.

Dabei weist jedes Verriegelungsteil einen an das Kopfstück anschließenden Steg auf, welcher in Aussparungen nur einer Lamelle gelagert ist, wobei das Kopfstück des Verriegelungsteils eine größere Breite als der Steg aufweist.In this case, each locking member has a subsequent to the headpiece web, which is mounted in recesses of only one blade, wherein the head piece of the locking member has a greater width than the web.

Der in die Aussparungen einer Lamelle eingesetzte Steg bewirkt eine stabile Lagerung des Verriegelungsteils in der Lamelle und sorgt für eine korrekte Positionierung des Kopftstücks des Verriegelungsteils zwischen zwei Lamellen, so dass dieses seine Funktion der Lagesicherung der Lamellen gegen ein seitliches Verschieben erfüllen kann.The web inserted in the recesses of a lamella causes a stable mounting of the locking part in the lamella and ensures a correct Positioning the head piece of the locking part between two slats, so that this can fulfill its function of securing the position of the slats against lateral displacement.

Generell bilden die Aussparungen Linearanordnungen in Auf- beziehungsweise Abrollrichtung des Sonnenschutzbehangs, so dass die Längsachsen der Stege der Verriegelungsteile, die in diese Aussparungen eingesetzt sind, ebenfalls in dieser Richtung verlaufen.In general, the recesses form linear arrangements in the upward or unrolling direction of the sun protection curtain, so that the longitudinal axes of the webs of the locking parts which are inserted in these recesses also run in this direction.

Wenn das Kopfstück eines Verriegelungsteils mit etwas Spiel zwischen zwei Lamellen gelagert ist, können sich das Verriegelungsteil und insbesondere der Steg etwas in Längsrichtung bewegen.If the head piece of a locking part is supported with a little clearance between two slats, the locking part and in particular the web can move somewhat in the longitudinal direction.

Um eine derartige unerwünschte Bewegung des Verriegelungsteils zu vermeiden, weist vorteilhaft das Verriegelungselement einen Quersteg auf, dessen Längsachse erstreckt zur Längsachse des Stegs verläuft.In order to avoid such unwanted movement of the locking part, advantageously, the locking element has a transverse web, whose longitudinal axis extends to the longitudinal axis of the web.

Dabei steht der Quersteg beidseits über den Steg hervor, wobei die Kontur des Querstegs an die Lamellensegmente der Lamellen angepasst ist.Here, the crosspiece protrudes on both sides over the web, wherein the contour of the crosspiece is adapted to the slat segments of the slats.

Durch den Quersteg ist somit das gesamte Verriegelungsteil gegen ein unerwünschtes Verschieben gesichert in der jeweiligen Lamelle gelagert, da es formschlüssig in der Struktur der Lamellensegmente liegt.By the cross bar thus the entire locking member is secured against unwanted displacement stored in the respective blade, since it is positively in the structure of the slat segments.

Alternativ münden an gegenüberliegenden Seitenwänden des Stegs eines Verriegelungselements Noppen aus.Alternatively, nubs open out on opposite side walls of the web of a locking element.

Diese Noppen bilden eine reibschlüssige Verbindung mit den an die Aussparungen angrenzenden Rändern der Aussparungen in einer Lamelle und sorgen somit ebenfalls für eine Lagesicherung des Verriegelungsteils in der Lamelle.These knobs form a frictional connection with the adjacent edges of the recesses of the recesses in a lamella and thus also ensure a secure position of the locking member in the lamella.

Generell kann ein Verriegelungsteil zur Lagesicherung in einer Lamelle sowohl mit einem Quersteg als auch mit Noppen ausgestattet sein.In general, a locking member for securing the position in a lamella can be equipped both with a transverse web and with nubs.

Besonders vorteilhaft sind die Aussparungen in den Lamellen zur Aufnahme von Verriegelungsteilen Ausfräsungen oder Ausstanzungen.Particularly advantageous are the recesses in the slats for receiving locking parts cutouts or punched.

Die Aussparungen in den Lamellen können somit rationell und hochgenau hergestellt werden.The recesses in the slats can thus be produced efficiently and with high precision.

Gemäß einer besonders vorteilhaften Ausgestaltung der Erfindung sind die Aussparungen in einem Vorgang mit dem Zuschneiden von Lamellen hergestellt.According to a particularly advantageous embodiment of the invention, the recesses are made in one operation with the cutting of slats.

Bei Zuschneiden von Lamellen aus einem langen Grundmaterial können somit mit dem Sägevorgang, mit dem die Lamellen ausgeschnitten werden, gleichzeitig an die Schnittlinie zwischen den Lamellen beidseitig angrenzend die Aussparungen durch Einfräsen oder Ausstanzen eingebracht werden. Damit wird eine weitere Rationalisierung des Herstellungsprozesses der Lamellen erzielt.When cutting slats from a long base material can thus be introduced by milling or punching simultaneously on the cutting line between the slats on both sides adjacent to the cutting process, with the sawing process with which the slats are cut. This achieves a further rationalization of the manufacturing process of the slats.

Figur 1 zeigt die wesentlichen Komponenten der erfindungsgemäßen Sonnenschutzeinrichtung 1, die insbesondere als Sonnenschutz an Fenstern von Gebäuden und dergleichen eingesetzt werden kann. FIG. 1 shows the essential components of the sun protection device 1 according to the invention, which can be used in particular as a sunscreen on windows of buildings and the like.

Die Sonnenschutzeinrichtung 1 umfasst einen Sonnenschutzbehang 2, der auf einer Welle 3 auf- und abgerollt werden kann. Figur 1 zeigt den an der Welle 3 abgerollten Sonnenschutzbehang 2. Der Sonnenschutzbehang 2 ist dann in einer vertikalen Ebene orientiert und liegt in der Öffnung eines Fensters oder dergleichen.The sun protection device 1 comprises a sunshade curtain 2 which can be rolled up and unrolled on a shaft 3. FIG. 1 shows the rolled on the shaft 3 Sonnenschutzbehang 2. The Sonnenschutzbehang 2 is then oriented in a vertical plane and lies in the opening of a window or the like.

Der Sonnenschutzbehang 2 ist aus einer Mehrfachanordnung von einzelnen Lamellen 4 aufgebaut. Figur 2 zeigt zwei miteinander gekoppelte Lamellen 4, die in der vertikalen Ebene des auf der Welle 3 abgerollten Sonnenschutzbehangs 2, wie in Figur 1 dargestellt, orientiert sind.The Sonnenschutzbehang 2 is constructed from a multiple arrangement of individual slats 4. FIG. 2 shows two mutually coupled slats 4, in the vertical plane of the unrolled on the shaft 3 Sonnenschutzbehangs 2, as in FIG. 1 represented, oriented.

Die Lamellen 4 sind jeweils in sich steif ausgebildet, das heißt sie weisen eine so große Materialstärke auf, dass diese formstabil und nicht biegsam sind.The slats 4 are each rigid in itself, that is, they have such a large material thickness that they are dimensionally stable and not flexible.

Die Lamellen 4 bestehen aus metallischen Werkstoffen wie Aluminium oder Edelstahl.The slats 4 are made of metallic materials such as aluminum or stainless steel.

Im vorliegenden Ausführungsbeispiel besteht der Sonnenschutzbehang 2 aus einer Mehrfachanordnung von identisch ausgebildeten Lamellen 4. Jede Lamelle 4 wiederrum besteht aus einer Mehrfachanordnung von identisch ausgebildeten Lamellensegmenten 5. Figur 2a zeigt eine vergrößerte Einzel Darstellung eines solchen Lamellensegments 5.In the present embodiment, the Sonnenschutzbehang 2 consists of a multiple arrangement of identically designed lamellae 4. Each lamella 4 in turn consists of a multiple arrangement of identically formed Slat segments 5. FIG. 2a shows an enlarged single representation of such a slat segment. 5

Jedes Lamellensegment 5 umfasst ein erstes Teilsegment 6, das in der Anordnung gemäß Figur 2 in einer vertikalen Ebene (y-Ebene) verlaufend angeordnet ist. In diesem Teilsegment 6 ist eine Anordnung von Lichtschlitzen 7 angeordnet, die sich im Wesentlichen über die gesamte Breite der Lamelle 4 erstrecken. Die einzelnen Lichtschlitze 7 können durch Stege 15, welche Bestandteile des Teilsegments 6 sind, getrennt sein.Each slat segment 5 comprises a first sub-segment 6, which in the arrangement according to FIG. 2 is arranged to run in a vertical plane (y-plane). In this sub-segment 6, an array of light slots 7 is arranged, which extend substantially over the entire width of the lamella 4. The individual light slots 7 can be separated by webs 15, which are components of the subsegment 6.

Oberhalb des ersten Teilsegments 6 mit dem Lichtschlitz 7 schließt ein vollständig lichtundurchlässig ausgebildetes zweites Teilsegment 8 an. Wie insbesondere aus Figur 2a ersichtlich, besteht das zweite Teilsegment 8 aus einem an dem oberen Rand des ersten Teilsegments 6 anschließenden, in x-Richtung verlaufen Abschnitt 8a, an welchen ein in y-Richtung abschließender Abschnitt 8b anschließt. An diesem Abschnitt 8b wiederrum schließt ein in y-Richtung verlaufender Abschnitt 8c an. Diese drei Abschnitte 8a-8c bilden ein rechteckförmiges Profilstück an der Außenseite der Lamelle 4 aus, das den einfallenden Sonnenstrahlen (in Figur 2 mit S gekennzeichnet) zugewandt ist. Von diesem rechteckigen Profilstück mündet ein schräg nach oben verlaufender Abschnitt 8d des Teilsegments 8 aus, der zum unteren Rand des ersten Teilsegments 6 der nächsten Lamellensegmente 5 hin verläuft.Above the first subsegment 6 with the light slot 7, a second subsegment 8, which is completely opaque, terminates. As in particular from FIG. 2a it can be seen, the second sub-segment 8 consists of a subsequent to the upper edge of the first sub-segment 6, extending in the x-direction section 8a, which is followed by a final in the y-direction section 8b. At this section 8b, in turn, a section 8c extending in the y-direction adjoins. These three sections 8a-8c form a rectangular profile piece on the outside of the lamella 4, which the incident sun rays (in FIG. 2 marked with S) facing. From this rectangular profile piece opens an obliquely upwardly extending portion 8d of the sub-segment 8, which extends to the lower edge of the first sub-segment 6 of the next slat segments 5 out.

Durch diese Ausbildung der Lamellensegmente 5 wird eine direkte Sonneneinstrahlung durch die Lichtschlitze 7 weitgehend verhindert. Vielmehr gelangt nur in einem engen Winkelbereich einfallendes Sonnenlicht nach Reflexion an den Grenzflächen des Lamellensegments 5, insbesondere des Abschnitts 8d des zweiten Teilsegments 8, durch die Lichtschlitze 7. Damit wird durch die spezifische Ausbildung der Struktur der Lamellensegmente 5 ein kontrollierter Lichteinfall durch die Lichtschlitze 7 erhalten.This design of the lamellar segments 5 direct sunlight is largely prevented by the light slots 7. Rather, only in a narrow angular range incident sunlight after reflection at the boundary surfaces of the lamellar segment 5, in particular of the section 8d of the second subsegment 8, through the light slots 7. Thus, by the specific formation of the structure of the lamellar segments 5, a controlled light incidence through the light slots. 7 receive.

Wie aus Figur 2 ersichtlich, sind die einzelnen Lamellen 4 in y-Richtung hintereinander angeordnet und über Gelenkverbindungen 9 gelenkig miteinander verbunden. Zur Ausbildung der Gelenkverbindungen 9 ist an jedem unteren Rand einer Lamelle 4 ein erstes Gelenkelement 10 vorgesehen, während am oberen Rand der Lamelle 4 ein zum ersten Gelenkelement 10 komplementäres zweites Gelenkelement 11 vorgesehen ist.How out FIG. 2 can be seen, the individual slats 4 are arranged in the y-direction one behind the other and articulated joints 9 together connected. To form the articulated joints 9, a first joint element 10 is provided at each lower edge of a lamella 4, while at the upper edge of the lamella 4, a second joint element 11 complementary to the first joint element 10 is provided.

Die Gelenkelemente 10, 11 sind einstückig mit der jeweiligen Lamelle 4 ausgebildet und erstrecken sich vorzugsweise über die gesamte Breite der Lamelle 4, wobei die Querschnitte der Gelenkelemente 10, 11 über die gesamte Breite konstant sind.The hinge elements 10, 11 are integrally formed with the respective lamella 4 and preferably extend over the entire width of the lamella 4, wherein the cross sections of the hinge elements 10, 11 are constant over the entire width.

Das erste Gelenkelement 10 weist einen im Wesentlichen kreisförmigen Querschnitt auf, wobei das Gelenkelement 10 einen Hohlraum umschließt, der an der Unterseite eine Ausmündung aufweist. Alternativ kann das erste Gelenkelement 10 hakenförmig ausgebildet sein.The first hinge element 10 has a substantially circular cross-section, wherein the hinge element 10 encloses a cavity having an opening at the bottom. Alternatively, the first joint element 10 may be hook-shaped.

Das hierzu komplementär ausgebildete Gelenkelement 11 weist an einem freien Ende eine kreisförmige Querschnittsverbreiterung auf.The thereto complementary formed hinge member 11 has at a free end on a circular cross-sectional widening.

Zur Herstellung der Gelenkverbindung 9 wird die kreisförmige Querschnittsverbreiterung des zweiten Gelenkelements 11 in den Hohlraum des ersten Gelenkelements 10 eingeschoben. Damit ist die Gelenkverbindung 9 hergestellt, so dass die zwei so verbundenen Lamellen 4 in der x-y Ebene gegeneinander geschwenkt werden können.To produce the articulated connection 9, the circular cross-sectional broadening of the second articulated element 11 is inserted into the cavity of the first articulated element 10. Thus, the hinge connection 9 is made, so that the two lamellae 4 thus connected in the x-y plane can be pivoted against each other.

Wenn die Gelenkelemente 10, 11 zweier benachbarter Lamellen 4 ineinander eingeschoben sind, können die Lamellen 4 noch in deren Längsrichtung gegeneinander verschoben werden. Um diese Verschiebbarkeit zu unterbinden und so eine Lagesicherung der Lamellen 4 zu erzielen, sind, wie in Figur 3 dargestellt, Verriegelungsteile 12 vorgesehen, die von der Oberseite des Sonnenschutzbehangs 2 in entsprechende Aufnahmen am Rand der Lamellen 4 eingesetzt werden. Die Figuren 4a und 4b zeigen ein solches Verriegelungsteil 12 in einer Einzeldarstellung.When the joint elements 10, 11 of two adjacent lamellae 4 are inserted into one another, the lamellae 4 can still be displaced relative to one another in their longitudinal direction. In order to prevent this displacement and to achieve a positional securing of the slats 4, as in FIG. 3 illustrated, locking members 12 are provided, which are used by the upper side of the Sonnenschutzbehangs 2 in corresponding receptacles on the edge of the slats 4. The FIGS. 4a and 4b show such a locking member 12 in a single representation.

Die Figuren 5 und 6 zeigen die Aufnahmen für die Verriegelungsteile 12, die in Form von Aussparungen 13, 13a, 13b in identischer Weise im Bereich beider längsseitigen Ränder jeder Lamelle 4 eingearbeitet sind.The FIGS. 5 and 6 show the receptacles for the locking parts 12, which are incorporated in the form of recesses 13, 13a, 13b in an identical manner in the region of both longitudinal edges of each blade 4.

Die Aussparungen 13, 13a, 13b werden durch Fräs- oder Stanzvorgange in die einzelnen Lamellen 4 eingearbeitet. Dabei sind erste Aussparungen 13 dadurch gebildet, dass die Teilsegmente 8 der einzelnen Lamellensegmente 5 einer Lamelle 4 vollständig abgetragen sind, so dass sich diese Aussparungen bis zur Ebene der Teilsegmente 6, in welchen die Lichtschlitze 7 eingearbeitet sind erstrecken. Wie insbesondere aus Figur 6 ersichtlich, weisen die identisch ausgebildeten Aussparungen 13 einen rechteckigen Querschnitt auf.The recesses 13, 13a, 13b are incorporated by milling or punching process in the individual blades 4. Here, first recesses 13 are formed by the fact that the sub-segments 8 of the individual slat segments 5 of a blade 4 are completely removed, so that these recesses extend to the level of the sub-segments 6, in which the light slots 7 are incorporated. As in particular from FIG. 6 can be seen, the identically shaped recesses 13 have a rectangular cross-section.

Weiterhin ist am oberen Rand jeder Lamelle 4 im Bereich des Gelenkelements 11 eine Aussparung 13a in Form einer rechteckigen Ausnehmung in einer Ecke der Lamelle 4 vorgesehen. Eine entsprechende Aussparung 13b in Form einer Ausnehmung ist in der gegenüberliegenden Ecke im Bereich des Gelenkelements 10 vorgesehen.Furthermore, a recess 13a in the form of a rectangular recess in a corner of the lamella 4 is provided at the upper edge of each lamella 4 in the region of the joint element 11. A corresponding recess 13b in the form of a recess is provided in the opposite corner in the region of the hinge element 10.

Figur 5 zeigt zwei Lamellen 4 mit einander gegenüberliegenden längsseitigen Rändern, wobei die Längsachsen dieser Lamellen 4 entlang einer Geraden verlaufen. Diese Anordnung veranschaulicht den Vorgang der Konfektionierung der Lamellen 4, indem diese mit einem Sägewerkzeug aus einem langen stangenförmigen Grundmaterial in der gewünschten Länge zugeschnitten werden. Das Schneiden zur Trennung der beiden in Figur 5 dargestellten Lamellen 4 erfolgt längs einer Schnittlinie A. Während dieses Schneid- oder Sägevorgangs werden simultan entlang der Fräslinien F1, F2 die Aussparungen 13 in die längsseitigen Ränder der Lamellen 4 eingearbeitet. FIG. 5 shows two blades 4 with opposite longitudinal edges, wherein the longitudinal axes of these blades 4 extend along a straight line. This arrangement illustrates the process of assembling the sipes 4 by cutting them with a sawing tool of a long bar-shaped base material of the desired length. The cutting to separate the two in FIG. 5 shown slats 4 along a section line A. During this cutting or sawing process, the recesses 13 are simultaneously incorporated along the milling lines F 1 , F 2 in the longitudinal edges of the slats 4.

Zur Lagesicherung der Lamellen 4 gegen eine Längsverschiebung werden die identisch ausbildeten Verriegelungsteile von oben in die Aussparungen 13, 13a, 13b an beiden längsseitigen Rändern der einzelnen Lamellen 4 eingesetzt.To secure the position of the slats 4 against longitudinal displacement, the identically formed locking parts are inserted from above into the recesses 13, 13a, 13b at both longitudinal edges of the individual slats 4.

Die Figuren 4a und 4b zeigen das Verriegelungsteil 12 in einer Einzeldarstellung. Das Verriegelungsteil 12 besteht aus Kunststoff. Dieses Verriegelungsteil 12 umfasst ein Kopfstück 14 sowie einen an das Kopfstück 14 angrenzenden Steg 15, der im Wesentlichen in Form eines langgestreckten Quaders ausgebildet ist. Die Breite des Kopfstücks 14 ist größer als die Breite des Stegs 15, so dass das Kopfstück 14 über die Seitenwände 15a, 15b des Stegs 15 hervorsteht. Die Unterseite des Kopfstücks 14 ist an dem dem Steg 15 zugewandten Ende abgeschrägt (Figur 4a).The FIGS. 4a and 4b show the locking member 12 in a single view. The locking member 12 is made of plastic. This locking part 12 comprises a head piece 14 and a web 15 which adjoins the head piece 14 and which is formed essentially in the form of an elongated cuboid. The width of the head piece 14 is greater than the width of the web 15, so that the head piece 14 projects beyond the side walls 15a, 15b of the web 15. The underside of the head piece 14 is beveled at the end facing the web 15 ( FIG. 4a ).

Weiterhin umfasst das Verriegelungsteil 12 einen Quersteg 16, dessen Längsachse senkrecht zur Längsachse des Stegs 15 verläuft und der über die Seitenwände 15a, 15b des Stegs 15 hervorsteht. Die Kontur des Querstegs 16 ist an die Konturen der Lamellensegmente 5 der Lamellen 4 angepasst.Furthermore, the locking part 12 comprises a transverse web 16 whose longitudinal axis is perpendicular to the longitudinal axis of the web 15 and which projects beyond the side walls 15a, 15b of the web 15. The contour of the cross bar 16 is adapted to the contours of the slat segments 5 of the slats 4.

Schließlich weist das Verriegelungsteil 12 Noppen 17 auf, die von den Seitenwänden 15a, 15b des Stegs 15 hervorstehen.Finally, the locking part 12 has knobs 17 which project from the side walls 15a, 15b of the web 15.

Sämtliche vorgenannten Komponenten des Verriegelungsteils sind Bestandteil eines Kunststoff-Spritzgussteils. Das so ausbildete Verriegelungsteil 12 ist spiegelsymmetrisch bezüglich einer durch dessen Längsachse verlaufenden Symmetrieebene.All of the aforementioned components of the locking part are part of a plastic injection molded part. The thus formed locking part 12 is mirror-symmetrical with respect to a plane passing through its longitudinal axis of symmetry.

Figur 3 zeigt eine Anordnung mehrerer gelenkig verbundener Lamellen 4 der Sonnenschutzeinrichtung 1, die mit den Verriegelungsteilen 12 gegen unkontrollierte Verschiebungen in deren Längsrichtung gesichert sind. FIG. 3 shows an arrangement of a plurality of hingedly connected slats 4 of the sun protection device 1, which are secured with the locking parts 12 against uncontrolled displacements in the longitudinal direction.

Das Kopfstück 14 eines Verriegelungsteils ist damit im Bereich der Gelenkverbindung 9 zweier Lamellen 4 gelagert. Dabei liegt das Kopfstück 14 in der Aussparung 13a einer ersten Lamelle 4 und in der Aussparung 13b der angrenzenden Lamelle 4. Der Steg 15 des Verriegelungsteils liegt in den Aussparungen 13, 13a, 13b in den Lamellensegmenten 5 einer jeden Lamelle 4 und erstreckt sich somit nahezu über die gesamte Breite einer Lamelle 4. Das Verriegelungsteil 12 wird von oben an die Lamelle 4 aufgesetzt, wodurch das Kopfstück 14 und der Steg 15 in die jeweiligen Aussparungen 13, 13a, 13b eingesetzt werden. Eine Bewegung des Verriegelungsteils in dessen Längsrichtung wird dabei durch den Quersteg 16 verhindert, der formschlüssig in den Bereich zwischen zwei Lamellensegmenten 5 eingerastet ist. Weiterhin verhindern auch die Noppen 17 am Steg 15 des Verriegelungsteils 12 toleranzbedingte Verschiebungen des Verriegelungsteils in dessen Längsrichtung, da die Noppen 17 reibschlüssig an den die Aussparungen 13, 13a, 13b begrenzenden Rändern der Lamellensegmente 5 anliegen. Prinzipiell kann ein Verriegelungsteil 12 zur Lagesicherung an den Aussparungen 13, 13a, 13b auch nur mit Noppen 17 oder alternativ nur mit einem Quersteg 15 ausgestattet sein.The head piece 14 of a locking part is thus mounted in the region of the articulated connection 9 of two blades 4. In this case, the head piece 14 is located in the recess 13a of a first blade 4 and in the recess 13b of the adjacent blade 4. The web 15 of the locking member lies in the recesses 13, 13a, 13b in the blade segments 5 of each blade 4 and thus extends almost over the entire width of a blade 4. The locking member 12 is placed from above to the blade 4, whereby the head piece 14 and the web 15 are inserted into the respective recesses 13, 13a, 13b. A movement of the locking member in its longitudinal direction is prevented by the transverse web 16, which is positively locked in the region between two lamella segments 5. Furthermore, the knobs 17 prevent on the web 15 of the locking member 12 tolerance-related displacements of the locking member in the longitudinal direction, since the knobs 17 frictionally abut the recesses 13, 13a, 13b limiting edges of the lamella segments 5. In principle, a locking part 12 for securing the position at the recesses 13, 13a, 13b may also be equipped only with nubs 17 or alternatively only with a transverse web 15.

Jedes Verriegelungsteil 12 ist so dimensioniert, dass dann, wenn das Verriegelungsteil 12 in den Aussparungen 13, 13a, 13b der Lamellen 4 gelagert ist, der seitliche Rand des Kopfstücks 14 etwas über die seitlichen Ränder der Lamellen 4 hervorstehen. Damit erfüllt das Kopfstück 14 seine Schutzfunktion derart, dass die Lamellen 4 bei Auf- und Abrollen des Sonnenschutzbehangs 2 nicht gegen Schienen oder sonstige Führungen schlagen, wodurch die Lamellen 4 gegen Beschädigungen geschützt sind.Each locking member 12 is dimensioned so that when the locking member 12 is mounted in the recesses 13, 13a, 13b of the blades 4, the lateral edge of the header 14 project slightly beyond the lateral edges of the blades 4. Thus, the headpiece 14 fulfills its protective function such that the slats 4 do not hit against rails or other guides when the sunshade curtain 2 rolls up and down, whereby the slats 4 are protected against damage.

Weiterhin steht das Verriegelungsteil, insbesondere dessen Kopfstück 14 auch nach oben über die Lamellen 4 geringfügig hervor. Damit erfüllen die Verriegelungsteile eine weitere Schutzfunktion derart, dass bei Auf- und Abrollen des Sonnenschutzbehangs 2 die Lamellen 4 nicht gegeneinander schlagen, was auch zu Beschädigungen der Lamellen 4 führen könnte.Furthermore, the locking part, in particular the head piece 14 also protrudes slightly above the slats 4 upwards. In order for the locking parts fulfill a further protective function such that when rolling up and unrolling the Sonnenschutzbehangs 2, the slats 4 do not strike against each other, which could also lead to damage to the slats 4.
