Definitions
- the invention relates to a darkening device for darkening a window opening of a roof window, in a building with a light-translucent curtain which can be wound onto a winding shaft between a darkening position and an open position, and with a frame having a cassette-shaped upper profile for receiving the winding shaft.
- Such blackout devices are used to avoid unwanted solar radiation, especially in the area of roof windows. It is desirable if the skylight window can be completely darkened by means of such a blackout blinds.
- the problem here is a light incident on the curtain over in particular directly or in the form of multiple reflections through the frame.
- German patent specification DE 60 2005 001 812 T2 shows a known darkening device, in which an unwanted passage of light, in particular by multiple reflections, is prevented by the frame by the curtain by providing a light-absorbing element within the frame.
- the object of the invention is to provide a darkening device with which an opening can be better darkened.
- the problem is solved in a darkening device of the type mentioned by a darkening element to darken a gap between the upper profile and the curtain.
- a darkening element to darken a gap between the upper profile and the curtain.
- a development of the invention is characterized in that the darkening element is elastically variable between a compressed state in which the extension of the darkening element in a transverse direction to the winding shaft corresponds to the gap in the open position and an expanded state in which the extension of the Darkening element in the transverse direction to the winding shaft corresponds to the gap in the darkening position.
- Such an elastic darkening element can adapt its extent to the respective gap and thus ensure a reliable darkening. Due to the elasticity, the friction between the darkening element and the curtain during winding or unwinding can be kept within limits at the same time.
- the obscuration element is also possible for the obscuration element to be movable between a retracted state in which the position of the obscuring element enables the gap to be darkened in the open position and an advanced state in which the position of the obscuring element enables the obscuring of the gap in the obscuring position is.
- a movable darkening element is particularly easy to produce. The friction during unwinding and winding can be largely minimized in this way.
- a particularly simple structure results when the darkening element is displaceable and / or pivotable.
- the darkening element should be displaceable and / or pivotable in the direction of the curtain. This results in a particularly simple structure and at the same time reliably ensures darkening of the gap.
- a particularly stable counter bearing for limiting the movement of the darkening element results when the obscuration element is movable in the direction of the curtain wound onto the winding shaft. It is particularly advantageous if the darkening element is movable in the direction of an upper region of the winding shaft, because here a drive for the movement of the darkening element is particularly easy to ensure.
- a further development is characterized in that the darkening element is movable by gravity into the advanced state.
- the darkening element can be driven by its own weight.
- a development of the invention is characterized in that the darkening element is mounted on the upper profile.
- the darkening element can be arranged in the upper profile, since here is the gap to be darkened. This results in a simple construction, when the darkening element is mounted movable, in particular displaceable and / or pivotable.
- the upper profile designed as a cassette has a bearing.
- the darkening element can be arranged in the bearing.
- the obscuring element is arranged pivotably about an axis in the bearing.
- the obscuring element may have an axis formed in particular as a thickening and a strip.
- the strip of the obscuration element may extend away from the axis of the obscuration element.
- the strip of the darkening element can rest on the curtain wound on the winding shaft.
- the axis of the obscuration element designed as a thickening element can be assigned to one side of the obscuration element which faces away from a light incidence opening.
- the darkening element is designed as a strip. This makes the production particularly easy. If the strip is elongated, it can be one-piece obscure the entire gap. In particular, the strip should be made of an opaque material, as this allows reliable darkening.
- the material for the darkening element is a synthetic resin material, metal, cardboard or a fabric or a mixture or a composite of the aforementioned materials provided. These materials are inexpensive and easy to process.
- the upper profile is a cassette.
- a cassette may be formed light-tight and allows almost complete darkening.
- the frame may also have lateral guide profiles. By means of these lateral guide profiles, an undesirable passage of light can be further improved. It is also advantageous if the lateral guide profiles terminate light-tight with the curtain and / or with a window frame and / or a window reveal. This allows for complete darkening.
- the curtain is associated with a lower end profile.
- This lower end profile can also provide a light-tight closure of the darkening device at a lower end.
- the lower end profile should be arranged on the end of the curtain facing away from the winding shaft.
- This lower end profile also serves to weight and thus tighten the curtain in a darkening position.
- the lower end profile identifies a handle for actuating the obscuring device. In this way, the structure is particularly simple and it is no additional actuating means required.
- Fig. 1 shows a schematic partial view of a darkening device 10 with the features of the invention in an open position. Shown is a Darkening device 10 for a roof window 11. The roof window 11 has a light incident direction 28. The darkening device 10 has a frame 12.
- the frame 12 has an upper profile 13 and lateral guide profiles 14, of which only a left lateral guide profile 14 can be seen in the figure.
- the upper profile 13 is formed in the embodiment shown as a cassette 13.
- the lateral guide profiles 14 have on their mutually facing longitudinal sides in each case an elongated opening 15, which will be discussed in more detail below.
- a winding shaft 16 is arranged in a known manner, on which a curtain 17 is wound in the open position shown.
- the winding shaft 16 is loaded in a known manner with a spring such that the curtain 17 can be wound on the winding shaft 16 under spring tension.
- a final profile 18 is arranged at the end facing away from the winding shaft 16 of the curtain 17.
- the end profile 18 has a handle 19 and is guided at its end faces facing away from each other in the grooves 15 of the lateral guide profiles 14, respectively.
- a darkening element 20 is arranged in the interior of the cassette 13, which rests in the state shown from above on the wound on the winding shaft 16 curtain 17. On the darkening element 20 will be discussed in more detail below.
- the cassette 13 and the lateral guide profiles 14 are arranged on the roof window 11 in a known manner light-tight. Furthermore, the curtain 17 and the end profile 18 are guided in a light-tight manner in the grooves 15 of the lateral guide profiles 14. In addition, the cassette 13 is formed light-tight.
- Fig. 2 time a schematic partial representation similar Fig. 1 in a darkening position of the darkening device 10.
- the curtain 17 is unwound from the winding shaft 16 so far that the lower end profile 18 at the lower end of the window opening of the roof window 11 not shown in the figure is light-tight.
- the lower end profile 18 and the blind 17 are light-tight in the grooves 15 of the lateral guide profiles 14, which in turn are arranged light-tight on the inside of the frame of the roof window 11, no light can laterally bypassing the lateral guide sections 14 or the blind 17 through get through the darkened window opening.
- the cassette 13 in turn is also arranged in a light-tight manner in the roof window 11 and itself also light-tight.
- Fig. 3 shows a cross section of the darkening device 10 in the in Fig. 1 shown open position.
- the cassette 13 has a receiving portion 21 for receiving the wound on the winding shaft 16 blind 17.
- the cassette 13 is closed by a front panel 22.
- Receiving section 21 and front panel 22 are integrally formed in the embodiment shown.
- a bearing 23 is arranged in the embodiment shown.
- the bearing 23 is formed as a groove open on one side.
- an axis 24 of the darkening element 20 is arranged.
- the obscuring element 20 further has a strip 25 extending from the axis 24 in the bearing to the right of the light entrance opening 28.
- the strip 25 is pivotally mounted about the axis 24 in the bearing 23 and rests in the figure by its own weight the wound on the winding shaft 16 curtain. In the figure, the strip 25 rests on the curtain 17 from above and is pushed up almost as far as the receiving section 21 by the curtain 17.
- FIG. 12 is a diagram similar to that of the obscuration device 10 Fig. 3 in the in Fig. 2 shown blackout position. It can clearly be seen that the curtain 17 is almost completely unwound from the winding shaft 16. In this way, the diameter of the winding package, which is formed by the wound on the winding shaft 16 curtain 17, has become significantly smaller than in Fig. 3 , The increasing gap between the wound on the winding shaft 16 curtain 17 and the cartridge 13 closes in the same way the strip 25 of the darkening element 20. By its own weight, the strip 25 is pivoted about the axis 24 in the bearing 23 down so far that he on the wound on the winding shaft 16 curtain 17 rests and closes the gap between curtain 17 and cassette 13 reliably light-tight.
- Fig. 5 shows an enlarged view of the cartridge 13 with therein arranged obscuring element 20. It can be seen that the bearing 23 has two holding portions 26, 27, which together with the front panel 22 form a groove open on one side. Adjacent to the open longitudinal side, the holding portions 26, 27 are bent towards each other, so that the groove tapers towards its open side.
- the axis 24 is arranged by insertion parallel to the longitudinal direction of the cassette 13 in this formed by the holding portions 26, 27 groove and can not pass through the taper to the open side out of the groove through this open side. In this way, a kind of pivotal position is formed, so that the arranged on the axis 24 elongated strip 25 is pivotally mounted about the axis 24 between holding portions 26, 27.
- the strip 25 is in the embodiment shown integral with the axis 24.
- a suitable, for example, thermoplastic resin material can be used. In this case, the production takes place for example by injection molding. But it is also possible to produce the strip 25 of cardboard, a metal such as aluminum die-cast, or a fabric. It is important that the strip 25 is formed light-tight.

Description
Die Erfindung betrifft eine Verdunkelungsvorrichtung zum Verdunkeln einer Fensteröffnung eines Dachflächenfensters, in einem Gebäude mit einem zwischen einer Verdunkelungsposition und einer offenen Position auf eine Wickelwelle aufwickelbaren lichtundurchlässigen Behang, und mit einem Rahmen, der ein als Kassette ausgebildetes oberes Profil zu Aufnahme der Wickelwelle aufweist.The invention relates to a darkening device for darkening a window opening of a roof window, in a building with a light-translucent curtain which can be wound onto a winding shaft between a darkening position and an open position, and with a frame having a cassette-shaped upper profile for receiving the winding shaft.
Derartige Verdunkelungsvorrichtungen, insbesondere Verdunkelungsrollos, werden benutzt, um unerwünschte Sonneneinstrahlung insbesondere im Bereich von Dachflächenfenstern zu vermeiden. Dabei ist es wünschenswert, wenn sich mittels eines derartigen Verdunkelungsrollos das Dachflächenfenster vollständig lichtdicht verdunkeln lässt. Problematisch ist hierbei ein Lichteinfall an dem Behang vorbei insbesondere direkt oder in Form von Mehrfachreflexionen durch den Rahmen.Such blackout devices, in particular blackout blinds, are used to avoid unwanted solar radiation, especially in the area of roof windows. It is desirable if the skylight window can be completely darkened by means of such a blackout blinds. The problem here is a light incident on the curtain over in particular directly or in the form of multiple reflections through the frame.
Die Deutsche Patentschrift
Es verbleibt allerdings das Problem, dass selbst bei Ausbildung des oberen Profiles als Kassette ein Zwischenraum zwischen dem auf die Wickelwelle aufgewickelten Behang und der Kassetteninnenseite eine variable Ausdehnung hat. So variiert ein verbleibender Spalt zwischen dem auf die Wickelwelle aufgewickelten Behang und der Innenseite der Kassette abhängig von der Dicke des Wickelpaketes. Gerade in der Verdunkelungsposition, wenn der Behang von der Wickelwelle abgewickelt ist, ergibt sich ein unerwünscht großer Spalt zwischen dem auf der Wickelwelle verbleibenden aufgewickelten Behang und der Innenseite der Kassette, durch den Licht hindurchtreten kann.However, there remains the problem that even with the formation of the upper profile as a cassette, a gap between the wound on the winding shaft curtain and the inside of the cassette has a variable extent. Thus, a remaining gap between the wound on the winding shaft curtain and the inside of the cassette varies depending on the thickness of the winding package. Especially in the darkening position, when the curtain is unwound from the winding shaft, there is an undesirably large gap between the remaining on the winding shaft wound curtain and the inside of the cassette through which light can pass.
Aufgabe der Erfindung ist es, eine Verdunkelungsvorrichtung anzugeben, mit der sich eine Öffnung besser verdunkeln lässt.The object of the invention is to provide a darkening device with which an opening can be better darkened.
Das Problem wird bei einer Verdunkelungsvorrichtung der eingangs genannten Art gelöst durch ein Verdunkelungselement zum Verdunkeln eines Spaltes zwischen dem oberen Profil und dem Behang. Mittels dieses Verdunkelungselementes wird ein Lichtdurchtritt durch den Spalt zuverlässig verhindert.The problem is solved in a darkening device of the type mentioned by a darkening element to darken a gap between the upper profile and the curtain. By means of this darkening element a passage of light through the gap is reliably prevented.
Eine Weiterbildung der Erfindung zeichnet sich dadurch aus, dass das Verdunkelungselement elastisch zwischen einem komprimierten Zustand, in dem die Ausdehnung des Verdunkelungselementes in eine Querrichtung zu der Wickelwelle dem Spalt in der offenen Position entspricht, und einem expandierten Zustand variabel ist, in dem die Ausdehnung des Verdunkelungselementes in die Querrichtung zu der Wickelwelle dem Spalt in der Verdunkelungsposition entspricht. Ein derartig elastisches Verdunkelungselement kann seine Ausdehnung dem jeweiligen Spalt anpassen und so für eine zuverlässige Verdunkelung sorgen. Durch die Elastizität lässt sich gleichzeitig die Reibung zwischen dem Verdunkelungselement und dem Behang beim Aufwickeln beziehungsweise Abwickeln in Grenzen halten.A development of the invention is characterized in that the darkening element is elastically variable between a compressed state in which the extension of the darkening element in a transverse direction to the winding shaft corresponds to the gap in the open position and an expanded state in which the extension of the Darkening element in the transverse direction to the winding shaft corresponds to the gap in the darkening position. Such an elastic darkening element can adapt its extent to the respective gap and thus ensure a reliable darkening. Due to the elasticity, the friction between the darkening element and the curtain during winding or unwinding can be kept within limits at the same time.
Es ist auch möglich, dass das Verdunkelungselement zwischen einem zurückgezogenen Zustand, in dem die Position des Verdunkelungselementes ein Verdunkeln des Spaltes in der offenen Position ermöglicht, und einem vorgeschobenen Zustand, in dem die Position des Verdunkelungselementes ein Verdunkeln des Spaltes in der Verdunkelungsposition ermöglicht, bewegbar ist. Ein solches bewegbares Verdunkelungselement lässt sich besonders einfach herstellen. Die Reibung beim Abwickeln und Aufwickeln kann auf diese Weise weitgehend minimiert werden. Ein besonders einfacher Aufbau ergibt sich dann, wenn das Verdunkelungselement verschiebbar und/oder verschwenkbar ist. Vorzugsweise sollte das Verdunkelungselement in Richtung auf den Behang verschiebbar und/oder verschwenkbar sein. Dies ergibt einen besonders einfachen Aufbau und gewährleistet gleichzeitig zuverlässig ein Verdunkeln des Spaltes. Ein besonders stabiles Gegenlager zum Begrenzen der Bewegung des Verdunkelungselementes ergibt sich dann, wenn das Verdunkelungselement in Richtung auf den auf die Wickelwelle aufgewickelten Behang bewegbar ist. Von besonderem Vorteil ist es, wenn das Verdunkelungselement in Richtung auf einen oberen Bereich der Wickelwelle bewegbar ist, weil hier ein Antrieb für die Bewegung des Verdunkelungselementes besonders leicht zu gewährleisten ist.It is also possible for the obscuration element to be movable between a retracted state in which the position of the obscuring element enables the gap to be darkened in the open position and an advanced state in which the position of the obscuring element enables the obscuring of the gap in the obscuring position is. Such a movable darkening element is particularly easy to produce. The friction during unwinding and winding can be largely minimized in this way. A particularly simple structure results when the darkening element is displaceable and / or pivotable. Preferably, the darkening element should be displaceable and / or pivotable in the direction of the curtain. This results in a particularly simple structure and at the same time reliably ensures darkening of the gap. A particularly stable counter bearing for limiting the movement of the darkening element results when the obscuration element is movable in the direction of the curtain wound onto the winding shaft. It is particularly advantageous if the darkening element is movable in the direction of an upper region of the winding shaft, because here a drive for the movement of the darkening element is particularly easy to ensure.
Eine Weiterbildung zeichnet sich dadurch aus, dass das Verdunkelungselement durch die Schwerkraft in den vorgeschobenen Zustand bewegbar ist. Dies ergibt einen besonders einfachen und langlebigen Antrieb. Insbesondere kann das Verdunkelungselement durch sein Eigengewicht angetrieben werden. Es ist aber auch möglich, eine Feder zum Bewegen des Verdunkelungselementes in den vorgeschobenen Zustand zu verwenden, auch in Kombination mit einem Antrieb durch die Schwerkraft. Auf diese Weise lassen sich die gewünschten Bewegungsparameter besonders einfach und definiert erzielen.A further development is characterized in that the darkening element is movable by gravity into the advanced state. This results in a particularly simple and durable drive. In particular, the darkening element can be driven by its own weight. But it is also possible to use a spring for moving the obscuring element in the advanced state, even in combination with a drive by gravity. In this way, the desired movement parameters can be achieved in a particularly simple and defined manner.
Eine Weiterbildung der Erfindung zeichnet sich dadurch aus, dass das Verdunkelungselement an dem oberen Profil gelagert ist. Dies ergibt einen einfachen Aufbau und ermöglicht die Lagerung des Verdunkelungselementes in unmittelbarer Nähe zu dem zu verdunkelnden Spalt. Insbesondere kann das Verdunkelungselement in dem oberen Profil angeordnet sein, da hier der zu verdunkelnde Spalt ist. Es ergibt sich ein einfacher Aufbau, wenn das Verdunkelungselement bewegbar, insbesondere verschiebbar und/oder verschwenkbar gelagert ist.A development of the invention is characterized in that the darkening element is mounted on the upper profile. This results in a simple structure and allows the storage of the darkening element in close proximity to the gap to be darkened. In particular, the darkening element can be arranged in the upper profile, since here is the gap to be darkened. This results in a simple construction, when the darkening element is mounted movable, in particular displaceable and / or pivotable.
Bei einer vorteilhaften Weiterbildung hat das als Kassette ausgebildete obere Profil ein Lager. Das Verdunklungselement kann in dem Lager angeordnet sein. Insbesondere ist das Verdunklungselement um eine Achse schwenkbar in dem Lager angeordnet. Das Verdunkelungselement kann eine insbesondere als Verdickung ausgebildete Achse und einen Streifen haben. Insbesondere kann sich der Streifen des Verdunklungselements von der Achse des Verdunklungselements weg erstrecken. Der Streifen des Verdunklungselements kann auf dem auf die Wickelwelle aufgewickelten Behang aufliegen. Insbesondere kann die als Verdickung ausgebildete Achse des Verdunklungselements einer Seite des Verdunkelungselements zugeordnet sein, die von einer Lichteinfallsöffnung abgewandt ist.In an advantageous development, the upper profile designed as a cassette has a bearing. The darkening element can be arranged in the bearing. In particular, the obscuring element is arranged pivotably about an axis in the bearing. The obscuring element may have an axis formed in particular as a thickening and a strip. In particular, the strip of the obscuration element may extend away from the axis of the obscuration element. The strip of the darkening element can rest on the curtain wound on the winding shaft. In particular, the axis of the obscuration element designed as a thickening element can be assigned to one side of the obscuration element which faces away from a light incidence opening.
Eine andere Weiterbildung der Erfindung zeichnet sich dadurch aus, dass das Verdunkelungselement als Streifen ausgebildet ist. Dies macht die Herstellung besonders einfach. Wenn der Streifen langgestreckt ausgebildet ist, kann er einteilig den gesamten Spalt verdunkeln. Insbesondere sollte der Streifen aus einem lichtundurchlässigen Material bestehen, da dies ein zuverlässiges Verdunkeln ermöglicht. Vorzugsweise ist als Material für das Verdunkelungselement ein Kunstharzmaterial, Metall, Pappe oder ein Gewebe beziehungsweise eine Mischung oder ein Verbund aus den vorgenannten Materialien vorgesehen. Diese Materialien sind kostengünstig und lassen sich einfach verarbeiten.Another development of the invention is characterized in that the darkening element is designed as a strip. This makes the production particularly easy. If the strip is elongated, it can be one-piece obscure the entire gap. In particular, the strip should be made of an opaque material, as this allows reliable darkening. Preferably, as the material for the darkening element is a synthetic resin material, metal, cardboard or a fabric or a mixture or a composite of the aforementioned materials provided. These materials are inexpensive and easy to process.
Bei der Erfindung ist es außerdem von Vorteil, wenn das obere Profil eine Kassette ist. Eine derartige Kassette kann lichtdicht ausgebildet sein und ermöglicht eine nahezu vollständige Verdunkelung. Der Rahmen kann außerdem seitliche Führungsprofile aufweisen. Mittels dieser seitlichen Führungsprofile lässt sich ein unerwünschter Lichtdurchtritt weiter verbessern. Es ist außerdem von Vorteil, wenn die seitlichen Führungsprofile lichtdicht mit dem Behang und/oder mit einem Fensterrahmen und/oder einer Fensterleibung abschließen. Dies ermöglicht eine vollständige Verdunkelung.In the invention, it is also advantageous if the upper profile is a cassette. Such a cassette may be formed light-tight and allows almost complete darkening. The frame may also have lateral guide profiles. By means of these lateral guide profiles, an undesirable passage of light can be further improved. It is also advantageous if the lateral guide profiles terminate light-tight with the curtain and / or with a window frame and / or a window reveal. This allows for complete darkening.
Eine andere vorteilhafte Ausgestaltung der Erfindung zeichnet sich dadurch aus, dass dem Behang ein unteres Abschlussprofil zugeordnet ist. Dieses untere Abschlussprofil kann für einen lichtdichten Abschluss der Verdunkelungsvorrichtung auch an einem unteren Ende sorgen. Insbesondere sollte dazu das untere Abschlussprofil am von der Wickelwelle abgewandten Ende des Behangs angeordnet sein. Dieses untere Abschlussprofil dient gleichermaßen zum Beschweren und damit Straffen des Behangs in einer Verdunkelungsposition. Es ist außerdem von Vorteil, wenn das untere Abschlussprofil einen Griff zum Betätigen der Verdunkelungsvorrichtung ausweist. Auf diese Weise wird der Aufbau besonders einfach und es ist kein zusätzliches Betätigungsmittel erforderlich.Another advantageous embodiment of the invention is characterized in that the curtain is associated with a lower end profile. This lower end profile can also provide a light-tight closure of the darkening device at a lower end. In particular, the lower end profile should be arranged on the end of the curtain facing away from the winding shaft. This lower end profile also serves to weight and thus tighten the curtain in a darkening position. It is also advantageous if the lower end profile identifies a handle for actuating the obscuring device. In this way, the structure is particularly simple and it is no additional actuating means required.

Wie sich der Figur entnehmen lässt, weist der Rahmen 12 ein oberes Profil 13 und seitliche Führungsprofile 14 auf, von denen in der Figur nur ein linkes seitliches Führungsprofil 14 zu sehen ist. Das obere Profil 13 ist bei dem gezeigten Ausführungsbeispiel als Kassette 13 ausgebildet. Die seitlichen Führungsprofile 14 haben an ihren einander zugewandten Längsseiten jeweils eine langgestreckte Öffnung 15, auf die nachfolgend noch näher eingegangen wird.As can be seen from the figure, the
Im Innern der Kassette 13 ist eine Wickelwelle 16 auf bekannte Weise angeordnet, auf die ein Behang 17 in der gezeigten offenen Position aufgewickelt ist. Die Wickelwelle 16 ist auf bekannte Weise mit einer Feder derart belastet, dass der Behang 17 unter Federspannung auf die Wickelwelle 16 aufgewickelt werden kann. Am von der Wickelwelle 16 abgewandten Ende des Behangs 17 ist ein Abschlussprofil 18 angeordnet. Das Abschlussprofil 18 weist einen Griff 19 auf und ist an seinen voneinander abgewandten Stirnseiten in den Nuten 15 der seitlichen Führungsprofile 14 jeweils geführt.Inside the
Wie sich der Figur weiter entnehmen lässt, ist im Innern der Kassette 13 ein Verdunkelungselement 20 angeordnet, das in dem gezeigten Zustand von oben auf dem auf die Wickelwelle 16 aufgewickelten Behang 17 aufliegt. Auf das Verdunkelungselement 20 wird nachfolgend noch näher eingegangen.As can be seen from the figure, a darkening
Die Kassette 13 und die seitlichen Führungsprofile 14 sind an dem Dachflächenfenster 11 auf bekannte Weise lichtdicht angeordnet. Ferner ist der Behang 17 und das Abschlussprofil 18 lichtdicht in den Nuten 15 der seitlichen Führungsprofile 14 geführt. Darüber hinaus ist auch die Kassette 13 lichtdicht ausgebildet.The
Am in der Figur gezeigten oberen linken von der Lichteintrittsöffnung 28 abgewandten Bereich der Kassette 13, wo die Frontblende 22 und der Aufnahmeabschnitt 21 aufeinander treffen, ist bei dem gezeigten Ausführungsbeispiel ein Lager 23 angeordnet. Das Lager 23 ist als einseitig offene Nut ausgebildet. In dem Lager 23 ist eine Achse 24 des Verdunkelungselementes 20 angeordnet. Das Verdunkelungselement 20 hat weiter einen sich von der Achse 24 in dem Lager in der Figur nach rechts der Lichteintrittsöffnung 28 zugewandt erstreckenden Streifen 25. Der Streifen 25 ist um die Achse 24 in dem Lager 23 schwenkbar angeordnet und liegt in der Figur durch sein Eigengewicht auf dem auf die Wickelwelle 16 aufgewickelten Behang auf. In der Figur liegt der Streifen 25 von oben her auf dem Behang 17 auf und ist nahezu bis an den Aufnahmeabschnitt 21 anliegend durch den Behang 17 hochgedrückt.At the upper left shown in the figure from the light inlet opening 28 facing away from the area of the
Die Achse 24 ist durch Einschieben parallel zur Längsrichtung der Kassette 13 in dieser durch die Halteabschnitte 26, 27 gebildeten Nut angeordnet und kann durch die Verjüngung zur offenen Seite hin nicht aus der Nut durch diese offene Seite hindurch gelangen. Auf diese Weise wird eine Art Schwenklage gebildet, so dass der an der Achse 24 angeordnete langgestreckte Streifen 25 um die Achse 24 schwenkbar zwischen Halteabschnitten 26, 27 gelagert ist. Der Streifen 25 ist bei dem gezeigten Ausführungsbeispiel einstückig mit der Achse 24. Als Material für den Streifen 25 kann ein geeignetes, beispielsweise thermoplastisches Kunstharzmaterial verwendet werden. In diesem Fall erfolgt die Herstellung beispielsweise im Spritzgussverfahren. Es ist aber auch möglich, den Streifen 25 aus Pappe, einem Metall, wie beispielsweise Aluminiumdruckguss, oder einem Gewebe herzustellen. Wichtig dabei ist, dass der Streifen 25 lichtdicht ausgebildet ist.The
