Definitions

  • the invention relates to a roller shutter box with a connecting element for connecting the roller shutter box to a frame element such as a window frame, door frame or the like, the connecting element having an outer holding strip, an inner holding strip and at least one sealing element, a positive connection with the frame element at least via the outer holding strip and the inner holding strip is produced, at least one sealing element is designed as an elastomeric sealing element, and is arranged between the outer holding strip and the inner holding strip.
  • Roller shutter boxes of this type are generally used to hold one or more roller shutters, which are used, for example, to darken, protect or isolate windows, doors, glazing or similar installations. For this reason, such roller shutter boxes are usually connected to the corresponding window frames, door frames, etc. at the top during the course of installation.
  • the object of the present invention is thus to avoid the disadvantages described and to provide a roller shutter box which reduces the risk of microbial infection.
  • the elastomeric sealing element is designed as a hollow profile.
  • the stated goal is achieved in particular by a combination of these features.
  • the sealing element is well protected from damage and direct mechanical environmental influences due to the arrangement between the outer and inner retaining strip, which ensures a long service life. Since it is not visible when the roller shutter box is connected to the window frame, it cannot be visually disturbing either, and painting, painting or other processing of the window frame or roller shutter box is possible without risk of damage to the sealing element in the connected state. It is advantageous to design at least one sealing element as an elastomeric sealing element, since elastomeric materials are easy to form, elastic and inexpensive. In addition, they can easily nestle against adjacent surfaces and therefore have good sealing properties. The compensation of larger thermal expansions can also be achieved without any problems.
  • elastomeric materials are particularly suitable due to the material properties. Of course, it may also be advantageous to have several sealing elements, if necessary to be provided in different places.
  • “Elastomeric” is understood to mean those materials which are dimensionally stable but are elastically deformable by tensile or compressive loading and return to their original shape when the load ceases to exist. This includes vulcanizates, natural rubber or silicone rubber, for example ethylene-propylene-diene rubber (EPDM). It can be provided, in addition to the positive connection or the positive connections between the connecting element and the frame element, to provide non-positive connections, such as screw connections.
  • roller shutter boxes generally extend over the entire width of the window, they have an elongated, essentially prismatic shape.
  • at least one sealing element extends over the entire length of the — generally narrow and elongated — connection between roller shutter box and window frame. It may even be advantageous if the sealing element extends beyond the length of the connection, in order to also prevent air flow on the sides of the sealing element. Thickened end elements can also be arranged on the end pieces of the sealing element, for example, in order to ensure an optimal seal.
  • the connecting element can be attached to the cover of the roller shutter box as an independent element of the roller shutter box.
  • This cover generally consists of two essentially mirror-like side elements, as well as side, top and bottom walls, at least one passage opening being provided in the area of the bottom walls through which the roller shutter can be unwound from the roller shutter box.
  • the connecting element is part of the casing. It is particularly advantageous if the connecting element is made in one piece with at least part of the casing. This can prevent any gaps in the seal between the connecting element and the cover of the roller shutter box. This also makes the structure more compact and easier.
  • the connecting element has a holding device in which the sealing element is held in a form-fitting manner. This means that gluing is no longer necessary and any incorrect gluing can be prevented.
  • the holding device is made in one piece with at least a substantial part of the remaining connecting element. This also prevents incorrect attachment of the holding device to the connecting element.
  • the sealing element is designed as a hollow profile, there is a particularly elastic shape that can easily adapt to different shapes.
  • this reinforcing element is designed in the form of a profile which is adapted to the shape of a profile chamber, the forces which act between the reinforcing element and the frame element can be distributed well by the reinforcing element.
  • connection between the frame element and the roller shutter box is additionally stabilized. If the guide lugs are made over the entire length of the connection, they additionally form a mechanical barrier to prevent foreign bodies from entering the connection area between the connection element and the frame element. Even if this does not result in a seal, at least larger particles can be prevented from penetrating into the area.
  • Another advantage is guiding the window frame while the connecting element and frame element, or roller shutter box and frame element, are being brought together, since the connecting element is usually first mounted on the remaining roller shutter box before it is connected to the frame element. When brought together, the frame element is guided into the correct position by the guide lugs so that the outer and inner retaining strip can easily connect to the connecting parts provided for this purpose, as well as the provided strips of the frame element.
  • At least one outer guide lug is further away from the rest of the connecting element than the inner guide element.
  • This unequal arrangement makes it easier to bring the frame element together with the connecting element.
  • the frame element can be inserted quickly and easily at an acute angle inclined towards the inner guide lug between the outer and inner guide lugs. It may also make sense to make the inner guide lug further away than the outer guide lug, this depends on the exact embodiment of the holding strips and other connecting elements.
  • this at least partially changes its shape when the described connection between the frame element and the connecting element is established. If this connection has not yet been established, that is to say the seal is not loaded by the frame element, then this is fully deployed, as a result of which at least one extension point of the seal element is as far as possible from the connection element or roller shutter box.
  • This extension point represents the point of the sealing element that is furthest away from the rest of the roller shutter box or connecting element in the unloaded state.
  • the sealing element does not extend beyond the guide lugs in the unloaded state, that is to say the guide lugs protrude beyond the sealing element. This can prevent the sealing element from being damaged or twisted before or during installation, since it is protected by the guide lugs.
  • disadvantageous warping of the sealing element by shear movements of the frame element on the connecting element can be prevented, since the frame element is centered first by the guide lugs before it comes into the vicinity of the sealing element.
  • a connecting surface of the frame element in the connected state with the connecting element is closer to the connecting element than the extension point of the sealing element in the unloaded state. This can ensure that the sealing element in the connected state lies directly on the connecting surface and is at least slightly deformed, as a result of which it achieves a seal.
  • Fig. 1 and Fig. 2 show an embodiment variant in which the connecting element 1 has an elastomeric sealing element 11 in a non-connected state with a frame element 20.
  • the connecting element 1 delimits a passage opening 2 on one side and is part of a casing of the roller shutter box.
  • the shell has two side plates 3, an upper plate 4, a lower plate 5 and two mirror-like side elements 6, only one side element 6 being shown.
  • the side plates 3, top plate 4, bottom plate 5 and side elements 6 can be at least partially inserted into one another or screwed together to form a shell that is as stable as possible, with the exception of any inspection openings that may be provided.
  • the connecting element 1 has an outer holding strip 12 and an inner holding strip 13, both of which are designed as an elongated outer strip 12a and inner strip 13a with an outer hook 12b or inner hook 13b. They are slightly bent away from each other, so that a frame element 20 (not shown), which has suitably shaped cavities or strips 22, can be easily clipped or pushed into one another.
  • Such a frame element 20 is then also guided by an outer guide lug 14 and an inner guide lug 16 and thus further stabilized, resulting in a firm connection with the frame element 20.
  • the outer guide lug 14 is arranged in a first plane E14, which - in relation to the intended installation position - lies below a second plane E16 on which the inner guide lug 16 is arranged.
  • the frame element 20 can thus be brought together with the connecting element, the frame element 20 of the inner guide nose 16 being slightly inclined. This further facilitates the connection. Since the connecting element is shown in a state not connected to the frame element 20, the sealing element 11 is unloaded and fully deployed. An extension point 11c is as far away from the connecting element or holding element 15 as possible, and lies on the third plane E11.
  • the sealing element 11 is designed as a hollow profile which has a cavity 11a and a belt 11b, which engages in a holding device 15 and thus fastens the sealing element 11 in the holding device 15.
  • This embodiment is particularly advantageous since a tight connection can be made in a positive manner without adhesive and the sealing element 11 can be replaced at any time.
  • the size of the sealing element 11 and the holding device 15 are dimensioned such that when the connecting element 1 and the frame element 20 are brought together, the sealing element 11 is compressed, but there is still enough space to be able to be compressed even further when the parts are thermally contracted. At the same time, however, the sealing element 11 should still have a tight connection to the frame element 20 even when the parts are thermally expanded.
  • the sealing element 11 When assembled, the sealing element 11 can simply be inserted or pushed into the holding device 15. Furthermore, the connecting element 1 has an -in Fig. 2 not shown-reinforcing element 17, which is designed as a metallic, curved profile. This profile can extend over the entire length of the connection, but can also be present only in sections in the form of a plurality of profiles arranged in a row.
  • FIG. 3 the same connecting element 1 as in Fig. 2 shown, but it is already connected to the frame element 20.
  • the frame element 20 has strips 22 which engage in the outer holding strip 12 and the inner holding strip 13 and thus form a positive connection.
  • the sealing element 11 is pressed against a connecting surface 21 of the frame element 20, whereby a tight connection between the connecting element 1 and the frame element 20 is produced.
  • the outer guide lug 14 and inner guide lug 16 bear directly on the frame element 20.
  • the connecting surface 21 lies on a fourth level E21, which lies above the third level E11, which ensures the tight connection.

Description

Die Erfindung betrifft einen Rollladenkasten mit einem Verbindungselement zum Verbinden des Rollladenkastens mit einem Rahmenelement wie einem Fensterrahmen, Türrahmen oder ähnlichen, wobei das Verbindungselement eine äußere Halteleiste, eine innere Halteleiste und zumindest ein Dichtungselement aufweist, eine formschlüssige Verbindung mit dem Rahmenelement zumindest über die äußere Halteleiste und die innere Halteleiste hergestellt wird, zumindest ein Dichtungselement als elastomeres Dichtungselement ausgeführt ist, und zwischen der äußeren Halteleiste und inneren Halteleiste angeordnet ist.The invention relates to a roller shutter box with a connecting element for connecting the roller shutter box to a frame element such as a window frame, door frame or the like, the connecting element having an outer holding strip, an inner holding strip and at least one sealing element, a positive connection with the frame element at least via the outer holding strip and the inner holding strip is produced, at least one sealing element is designed as an elastomeric sealing element, and is arranged between the outer holding strip and the inner holding strip.

Rollladenkästen dieser Art dienen in der Regel zur Aufnahme von einem oder mehreren Rollläden, welche beispielsweise zur Abdunkelung, zum Schutz, oder als Isolation von Fenstern, Türen, Verglasungen oder ähnlichen Installationen verwendet werden. Deswegen werden solche Rollladenkästen im Zuge des Einbaus in der Regel mit den entsprechenden Fensterrahmen, Türrahmen, etc. an deren Oberseite verbunden.Roller shutter boxes of this type are generally used to hold one or more roller shutters, which are used, for example, to darken, protect or isolate windows, doors, glazing or similar installations. For this reason, such roller shutter boxes are usually connected to the corresponding window frames, door frames, etc. at the top during the course of installation.

Aus der DE 102 12 294 A1 ist ein Zusammenfügungsset für einen Rollladenkasten bekannt, wobei ein Dichtprofil zwischen Bodenrevisionsteil und Blendrahmenebene angeordnet ist. Dies ist jedoch nachteilig, da so die in der Regel nicht sehr ansehnliche Dichtung sichtbar ist, und die Dichtung durch den direkten Zugang eventuellen Beschädigungen ausgesetzt ist. Außerdem muss bei nachträglicher Lackierung, Bemalung und dergleichen darauf geachtet werden, dass die Dichtung nicht beschädigt wird.From the DE 102 12 294 A1 an assembly set for a roller shutter box is known, a sealing profile being arranged between the floor inspection part and the frame level. However, this is disadvantageous since the seal, which is generally not very attractive, is visible and the seal is exposed to possible damage due to the direct access. In addition, care must be taken when retrofitting, painting and the like that the seal is not damaged.

In anderen, bereits bekannten, Ausführungsformen für Rollladenkästen sind Verbindungselemente vorgesehen, wobei im Inneren der Verbindung ein Dichtungsband eingeklebt wird, welches die Verbindung zwischen Rollladenkasten und Fensterrahmen abdichtet. Dies ist jedoch oft nachteilig, da handelsübliche Dichtungsbänder oft nicht dick genug sind, um eine ausreichende Abdichtung zu erreichen. Größenveränderungen der angrenzenden Teile durch Temperaturschwankungen können des Weiteren zu einer Verbreiterung des Raumes zwischen Fensterrahmen und Verbindungselement führen, welche unter Umständen nicht in vollem Maße vom Dichtungsband ausgeglichen werden kann. Außerdem kann sich im Laufe der Zeit durch die ständige Temperatureinwirkung der Klebstoff lösen und das Band verrutschen, was zu Lücken in der Dichtung führen kann. Auch kann es leicht durch falsches oder ungenaues Anbringen des Dichtungsbandes an dem Fensterrahmen bzw. Rollladenkasten zu solchen Lücken kommen.In other, already known, embodiments for roller shutter boxes, connecting elements are provided, a sealing tape being glued in the interior of the connection, which seals the connection between the roller shutter box and window frame. However, this is often disadvantageous since standard sealing tapes are often not thick enough to achieve an adequate seal. Changes in the size of the adjacent parts due to temperature fluctuations can also lead to a widening of the space between the window frame and the connecting element, which under certain circumstances cannot be fully compensated for by the sealing tape. In addition, the constant exposure to temperature can cause the adhesive to loosen and the tape to slip, which can lead to gaps in the seal. It can also easily pass through incorrect or inaccurate attachment of the sealing tape to the window frame or roller shutter box lead to such gaps.

In der EP 3 216 970 A1 wird eine Verbindungsanordnung für die Verbindung eines Rollladenkastens mit einem Fenster- oder Türrahmen beschrieben, wobei eine Dichtungslippe zwischen äußerer und innerer Halteleiste angeordnet ist. Dadurch wird das Dichtungselement vor Beschädigung und Korrosion geschützt. Dabei ist die Lippe meist am Kasten montiert und drückt im zusammengebauten Zustand auf den Rahmen. Nachteilig ist jedoch, dass die Größe der Dichtungslippe genau an die Größe des Zwischenraumes zwischen Rollladenkasten und Fenster- oder Türrahmen abgestimmt sein muss, da einerseits wenig Platz für die Dichtungslippe vorhanden ist, diese jedoch in einem zusammengefügten Zustand von Kasten und Rahmen mit genug Kraft auf den Rahmen drücken muss. Es kommt dabei auch oft bei den meist lang ausgeführten Dichtungslippen immer wieder zu undichten Stellen. Diese sonst unwesentlichen, sehr kleinen Undichtheiten können aufgrund der Temperaturunterschiede zwischen den Fensterseiten zu einer Kondensation von Wasser aus der durchziehenden Luft führen, was mikrobiellen Befall und Schimmelbildung begünstigt.In the EP 3 216 970 A1 describes a connection arrangement for connecting a roller shutter box to a window or door frame, wherein a sealing lip is arranged between the outer and inner retaining strip. This protects the sealing element from damage and corrosion. The lip is usually mounted on the box and, when assembled, presses on the frame. It is disadvantageous, however, that the size of the sealing lip must be precisely matched to the size of the space between the roller shutter box and the window or door frame, since on the one hand there is little space for the sealing lip, but in an assembled state of the box and frame with enough force must press the frame. There are often leaks in the mostly long sealing lips. Due to the temperature differences between the window sides, these otherwise insignificant, very small leaks can lead to condensation of water from the passing air, which favors microbial infestation and mold growth.

Aufgabe der vorliegenden Erfindung ist damit die beschriebenen Nachteile zu vermeiden und einen Rollladenkasten bereitzustellen, der das Risiko eines mikrobiellen Befalls vermindert.The object of the present invention is thus to avoid the disadvantages described and to provide a roller shutter box which reduces the risk of microbial infection.

Dies wird erfindungsgemäß dadurch erreicht, dass das elastomere Dichtungselement als Hohlprofil ausgeführt ist.This is achieved according to the invention in that the elastomeric sealing element is designed as a hollow profile.

Insbesondere durch eine Kombination dieser Merkmale wird das genannte Ziel erreicht. Durch Anordnung zwischen der äußeren und inneren Halteleiste ist das Dichtelement gut vor Beschädigungen und direkten mechanischen Umwelteinflüssen geschützt, wodurch eine hohe Lebensdauer erreicht wird. Da sie nicht sichtbar ist, wenn der Rollladenkasten mit dem Fensterrahmen verbunden ist, kann sie auch visuell nicht stören, und eine Lackierung, Bemalung oder sonstige Bearbeitung des Fensterrahmens, bzw. Rollladenkastens ist ohne Gefahr einer Beschädigung des Dichtungselements im verbundenen Zustand möglich. Es ist vorteilhaft, zumindest ein Dichtungselement als elastomeres Dichtungselement auszuführen, da elastomere Werkstoffe leicht formbar, elastisch und kostengünstig sind. Außerdem können sie sich leicht an anliegende Oberflächen anschmiegen und weisen daher gute abdichtende Eigenschaften auf. Der Ausgleich größerer Wärmedehnungen kann so auch problemlos erreicht werden. Es kann zwar sinnvoll sein, mehrere Dichtungselemente aus unterschiedlichen Material vorzusehen, jedoch sind elastomere Materialien aufgrund der Materialeigenschaften besonders geeignet. Selbstverständlich kann es auch vorteilhaft sein, mehrere Dichtungselemente, eventuell auch an unterschiedlichen Stellen vorzusehen. Dabei werden unter "elastomer" solche Materialien verstanden, welche formfest, aber durch Zug- oder Druckbelastung elastisch verformbar sind und bei Wegfallen der Belastung wieder ihre Ursprüngliche Form einnehmen. Darunter fallen Vulkanisate, Naturkautschuk oder Silikonkautschuk, beispielsweise Ethylen-Propylen-Dien-Kautschuke (EPDM). Es kann vorgesehen sein, zusätzlich zur formschlüssigen Verbindung bzw. den formschlüssigen Verbindungen zwischen Verbindungselement und Rahmenelement kraftschlüssige Verbindungen vorzusehen, wie beispielsweise Verschraubungen.The stated goal is achieved in particular by a combination of these features. The sealing element is well protected from damage and direct mechanical environmental influences due to the arrangement between the outer and inner retaining strip, which ensures a long service life. Since it is not visible when the roller shutter box is connected to the window frame, it cannot be visually disturbing either, and painting, painting or other processing of the window frame or roller shutter box is possible without risk of damage to the sealing element in the connected state. It is advantageous to design at least one sealing element as an elastomeric sealing element, since elastomeric materials are easy to form, elastic and inexpensive. In addition, they can easily nestle against adjacent surfaces and therefore have good sealing properties. The compensation of larger thermal expansions can also be achieved without any problems. Although it may make sense to provide several sealing elements made of different materials, elastomeric materials are particularly suitable due to the material properties. Of course, it may also be advantageous to have several sealing elements, if necessary to be provided in different places. “Elastomeric” is understood to mean those materials which are dimensionally stable but are elastically deformable by tensile or compressive loading and return to their original shape when the load ceases to exist. This includes vulcanizates, natural rubber or silicone rubber, for example ethylene-propylene-diene rubber (EPDM). It can be provided, in addition to the positive connection or the positive connections between the connecting element and the frame element, to provide non-positive connections, such as screw connections.

Da sich Rollladenkästen in der Regel über die gesamte Breite des Fensters erstrecken, weisen sie eine längliche, im Wesentlichen prismatische Form auf. Um eine möglichst lückenlose Dichtung zu erreichen ist es vorteilhaft, wenn sich zumindest ein Dichtungselement über die gesamte Länge der - in der Regel schmalen und länglichen - Verbindung zwischen Rollladenkasten und Fensterrahmen erstreckt. Es kann sogar vorteilhaft sein, wenn sich das Dichtungselement über die Länge der Verbindung hinaus erstreckt, um so auch einen Luftstrom an den Seiten des Dichtungselements zu verhindern. Auch können an den Endstücken des Dichtungselements beispielsweise verdickte Endelemente angeordnet sein, um eine optimale Dichtung zu gewährleisten.Since roller shutter boxes generally extend over the entire width of the window, they have an elongated, essentially prismatic shape. In order to achieve a seal that is as complete as possible, it is advantageous if at least one sealing element extends over the entire length of the — generally narrow and elongated — connection between roller shutter box and window frame. It may even be advantageous if the sealing element extends beyond the length of the connection, in order to also prevent air flow on the sides of the sealing element. Thickened end elements can also be arranged on the end pieces of the sealing element, for example, in order to ensure an optimal seal.

Das Verbindungselement kann als eigenständiges Element des Rollladenkastens an die Hülle des Rollladenkastens angebracht sein. Diese Hülle besteht in der Regel aus zwei im Wesentlichen spiegelgleichen Seitenelementen, sowie Seiten-, Ober- und Unterwänden, wobei zumindest eine Durchtrittsöffnung im Bereich der Unterwände vorgesehen ist, durch die der Rollladen aus dem Rollladenkasten abgewickelt werden kann. Vorteilhaft ist es aber, wenn das Verbindungselement Teil der Hülle ist. Besonders vorteilhaft ist, wenn das Verbindungselement mit zumindest einem Teil der Hülle einstückig ausgeführt ist. Dadurch können eventuell auftretende Dichtungslücken zwischen dem Verbindungselement und der Hülle des Rollladenkastens verhindert werden. Außerdem wird dadurch der Aufbau kompakter und einfacher.The connecting element can be attached to the cover of the roller shutter box as an independent element of the roller shutter box. This cover generally consists of two essentially mirror-like side elements, as well as side, top and bottom walls, at least one passage opening being provided in the area of the bottom walls through which the roller shutter can be unwound from the roller shutter box. However, it is advantageous if the connecting element is part of the casing. It is particularly advantageous if the connecting element is made in one piece with at least part of the casing. This can prevent any gaps in the seal between the connecting element and the cover of the roller shutter box. This also makes the structure more compact and easier.

Es ist günstig, wenn das Verbindungselement eine Haltevorrichtung aufweist, in welcher das Dichtungselement formschlüssig gehalten wird. Damit wird ein Aufkleben nicht mehr nötig und ein eventuell falsches Aufkleben kann verhindert werden. Besonders bevorzugt sind Ausführungsformen, bei denen die Haltevorrichtung mit zumindest einem wesentlichen Teil des restlichen Verbindungselements einstückig ausgeführt ist. Damit wird ebenso das falsche Anbringen der Haltevorrichtung an dem Verbindungselement verhindert.It is favorable if the connecting element has a holding device in which the sealing element is held in a form-fitting manner. This means that gluing is no longer necessary and any incorrect gluing can be prevented. Embodiments are particularly preferred in which the holding device is made in one piece with at least a substantial part of the remaining connecting element. This also prevents incorrect attachment of the holding device to the connecting element.

Da das Dichtungselement als Hohlprofil ausgeführt ist, ergibt sich eine besonders elastische Form, die sich besonders leicht verschiedenen Formen anpassen kann.Since the sealing element is designed as a hollow profile, there is a particularly elastic shape that can easily adapt to different shapes.

Außerdem bietet sie eine gute Dichtung in beide Richtungen, während beispielsweise Lippendichtungen in eine Richtung meist eine verminderte Dichtung aufweisen. Dadurch wird der Luftfluss von einer Seite zur anderen und die Kondensation von Wasser verhindert. Damit wird die Gefahr von mikrobiellen Befall stark gesenkt.It also offers a good seal in both directions, while lip seals in one direction, for example, usually have a reduced seal. This prevents air flow from one side to the other and water condensation. This greatly reduces the risk of microbial infestation.

Um die Stabilität des Verbindungselements zu erhöhen, kann es vorteilhaft sein, ein metallisches Verstärkungselement im Verbindungselement vorzusehen. Insbesondere wenn dieses Verstärkungselement in Form eines Profils ausgeführt ist, das an die Form einer Profilkammer angepasst ist, können die Kräfte, die zwischen Verstärkungselement und Rahmenelement wirken, gut durch das Verstärkungselement verteilt werden.In order to increase the stability of the connecting element, it can be advantageous to provide a metallic reinforcing element in the connecting element. In particular if this reinforcing element is designed in the form of a profile which is adapted to the shape of a profile chamber, the forces which act between the reinforcing element and the frame element can be distributed well by the reinforcing element.

Werden innere und äußere Führungsnasen vorgesehen, welche zusätzlich zu den Halteleisten am Rahmenelement im verbundenen Zustand anliegen, so wird die Verbindung zwischen Rahmenelement und Rollladenkasten zusätzlich stabilisiert. Werden die Führungsnasen über die gesamte Länge der Verbindung ausgeführt, so bilden sie zusätzlich noch eine mechanische Barriere um das Eindringen von Fremdkörpern in den Verbindungsbereich zwischen Verbindungselement und Rahmenelement zu verhindern. Auch wenn dadurch keine Abdichtung erreicht wird, so können doch zumindest größere Partikel daran gehindert werden, in den Bereich vorzudringen. Ein weiterer Vorteil ist, die Führung des Fensterrahmens während des Zusammenführens von Verbindungselement und Rahmenelement, bzw. von Rollladenkasten und Rahmenelement, da in der Regel meist zuerst das Verbindungselement am restlichen Rollladenkasten montiert wird, bevor dieser mit dem Rahmenelement verbunden wird. Bei Zusammenführung wird das Rahmenelement durch die Führungsnasen in die richtige Position geführt, damit die äußere und innere Halteleiste leicht mit den dafür vorgesehenen Verbindungsteilen wie dafür vorgesehenen Leisten des Rahmenelements verbinden kann.If inner and outer guide lugs are provided which, in addition to the retaining strips, bear against the frame element in the connected state, the connection between the frame element and the roller shutter box is additionally stabilized. If the guide lugs are made over the entire length of the connection, they additionally form a mechanical barrier to prevent foreign bodies from entering the connection area between the connection element and the frame element. Even if this does not result in a seal, at least larger particles can be prevented from penetrating into the area. Another advantage is guiding the window frame while the connecting element and frame element, or roller shutter box and frame element, are being brought together, since the connecting element is usually first mounted on the remaining roller shutter box before it is connected to the frame element. When brought together, the frame element is guided into the correct position by the guide lugs so that the outer and inner retaining strip can easily connect to the connecting parts provided for this purpose, as well as the provided strips of the frame element.

Besonders vorteilhaft ist, wenn zumindest eine äußere Führungsnase vom restlichen Verbindungselement weiter entfernt ist als das innere Führungselement. Durch diese ungleiche Anordnung wird das Zusammenführen des Rahmenelements mit dem Verbindungselement erleichtert. Das Rahmenelement kann in einem spitzen, der inneren Führungsnase zugeneigten Winkel zwischen der äußeren und inneren Führungsnase schnell und einfach eingeführt werden. Es kann zwar auch sinnvoll sein, die innere Führungsnase weiter entfernt auszuführen als die äußere Führungsnase, dies ist abhängig von der genauen Ausführungsform der Halteleisten und anderen verbindungsgebenden Elementen.It is particularly advantageous if at least one outer guide lug is further away from the rest of the connecting element than the inner guide element. This unequal arrangement makes it easier to bring the frame element together with the connecting element. The frame element can be inserted quickly and easily at an acute angle inclined towards the inner guide lug between the outer and inner guide lugs. It may also make sense to make the inner guide lug further away than the outer guide lug, this depends on the exact embodiment of the holding strips and other connecting elements.

Durch die elastische Ausführungsform des Dichtungselements verändert dieses zumindest teilweise seine Form, wenn die beschriebene Verbindung zwischen Rahmenelement und Verbindungselement hergestellt wird. Wenn diese Verbindung noch nicht hergestellt wird, die Dichtung also vom Rahmenelement nicht belastet wird, so ist dieses voll entfaltet, wodurch zumindest ein Erstreckungspunkt des Dichtungselements vom Verbindungselement bzw. Rollladenkasten so weit wie möglich entfernt ist. Dabei stellt dieser Erstreckungspunkt den Punkt des Dichtungselements dar, der im unbelasteten Zustand am weitesten vom restlichen Rollladenkasten, bzw. Verbindungselement entfernt ist.Due to the elastic embodiment of the sealing element, this at least partially changes its shape when the described connection between the frame element and the connecting element is established. If this connection has not yet been established, that is to say the seal is not loaded by the frame element, then this is fully deployed, as a result of which at least one extension point of the seal element is as far as possible from the connection element or roller shutter box. This extension point represents the point of the sealing element that is furthest away from the rest of the roller shutter box or connecting element in the unloaded state.

Besonders vorteilhaft ist, wenn sich das Dichtungselement im unbelasteten Zustand nicht über die Führungsnasen hinaus ausdehnt, also die Führungsnasen das Dichtungselement überragen. Dadurch kann verhindert werden, dass vor oder während des Einbaus das Dichtungselement beschädigt oder verdreht wird, da es durch die Führungsnasen geschützt wird. Während des Einbaus kann ein unvorteilhaftes Verziehen des Dichtungselements durch Scherbewegungen des Rahmenelements am Verbindungselement verhindert werden, da durch die Führungsnasen das Rahmenelement zuerst zentriert wird, bevor es in die Nähe des Dichtungselements kommt.It is particularly advantageous if the sealing element does not extend beyond the guide lugs in the unloaded state, that is to say the guide lugs protrude beyond the sealing element. This can prevent the sealing element from being damaged or twisted before or during installation, since it is protected by the guide lugs. During installation, disadvantageous warping of the sealing element by shear movements of the frame element on the connecting element can be prevented, since the frame element is centered first by the guide lugs before it comes into the vicinity of the sealing element.

Um eine optimale Dichtung zu erreichen, ist es vorteilhaft, wenn eine Verbindungsfläche des Rahmenelements im verbundenen Zustand mit dem Verbindungselement näher am Verbindungselement liegt als der Erstreckungspunkt des Dichtungselements in unbelasteten Zustand. Dadurch kann sichergestellt werden, dass das Dichtungselement im verbundenen Zustand direkt an der Verbindungsfläche anliegt und zumindest leicht deformiert wird, wodurch sie eine Abdichtung erreicht.In order to achieve an optimal seal, it is advantageous if a connecting surface of the frame element in the connected state with the connecting element is closer to the connecting element than the extension point of the sealing element in the unloaded state. This can ensure that the sealing element in the connected state lies directly on the connecting surface and is at least slightly deformed, as a result of which it achieves a seal.

In der Folge wird die vorliegende Erfindung anhand der in den Figuren dargestellten nicht einschränkenden Ausführungsvariante näher erläutert. Es zeigen:

Fig. 1
einen erfindungsgemäßen Rollladenkasten in einer schematischen Darstellung in einem Schnitt;
Fig. 2
ein Verbindungselement im Detail in einem Schnitt;
Fig. 3
ein Verbindungselement, verbunden mit einem Rahmenelement in einem Schnitt.
The present invention is explained in more detail below on the basis of the non-restrictive embodiment variant shown in the figures. Show it:
Fig. 1
a roller shutter box according to the invention in a schematic representation in a section;
Fig. 2
a connecting element in detail in a section;
Fig. 3
a connecting element connected to a frame element in one section.

Fig. 1 und Fig. 2 zeigen eine Ausführungsvariante, bei der das Verbindungselement 1 ein elastomeres Dichtungselement 11 aufweist in einem nicht verbunden Zustand mit einem Rahmenelement 20. Das Verbindungselement 1 begrenzt eine Durchtrittsöffnung 2 an einer Seite und ist Teil einer Hülle des Rollladenkastens. Fig. 1 and Fig. 2 show an embodiment variant in which the connecting element 1 has an elastomeric sealing element 11 in a non-connected state with a frame element 20. The connecting element 1 delimits a passage opening 2 on one side and is part of a casing of the roller shutter box.

Des Weiteren weist die Hülle zwei Seitenplatten 3, eine Oberplatte 4, eine Unterplatte 5 sowie zwei spiegelgleiche Seitenelemente 6 auf, wobei nur ein Seitenelement 6 dargestellt ist. Die Seitenplatten 3, Oberplatte 4, Unterplatte 5 und Seitenelemente 6 können zumindest zum Teil ineinandergesteckt bzw. miteinander verschraubt sein, um eine möglichst stabile Hülle zu bilden, mit Ausnahme eventuell vorgesehener Revisionsöffnungen. Das Verbindungselement 1 weist eine äußere Halteleiste 12 und eine innere Halteleiste 13 auf, wobei beide als eine längliche äußere Leiste 12a und innere Leiste 13a mit einer äußeren Verhakung 12b, bzw. inneren Verhakung 13b ausgeführt sind. Sie sind leicht voneinander weg gebeugt, wodurch ein nicht dargestelltes Rahmenelement 20, das geeignet geformte Hohlräume oder ebenso Leisten 22 aufweist, leicht eingeklipst oder ineinandergeschoben werden kann. Ein derartiges Rahmenelement 20 wird dann auch von einer äußeren Führungsnase 14 und einer inneren Führungsnase 16 geführt und damit weiter stabilisiert, wodurch sich eine feste Verbindung mit dem Rahmenelement 20 ergibt. Die äußere Führungsnase 14 ist in einer ersten Ebene E14 angeordnet, die - in Bezug auf die bestimmungsgemäße Einbauposition - unterhalb einer zweiten Ebene E16 liegt, auf der die innere Führungsnase 16 angeordnet ist. Damit kann das Rahmenelement 20 mit dem Verbindungselement zusammengeführt werden, wobei das Rahmenelement 20 der inneren Führungsnase 16 leicht zugeneigt ist. Dadurch wird das Verbinden weiter erleichtert. Da das Verbindungselement in einem mit dem Rahmenelement 20 nicht verbunden Zustand dargestellt ist, ist das Dichtungselement 11 unbelastet und voll entfaltet. Ein Erstreckungspunkt 11c ist so weit vom Verbindungselement bzw. Halteelement 15 entfernt wie möglich, und liegt auf der dritten Ebene E11.Furthermore, the shell has two side plates 3, an upper plate 4, a lower plate 5 and two mirror-like side elements 6, only one side element 6 being shown. The side plates 3, top plate 4, bottom plate 5 and side elements 6 can be at least partially inserted into one another or screwed together to form a shell that is as stable as possible, with the exception of any inspection openings that may be provided. The connecting element 1 has an outer holding strip 12 and an inner holding strip 13, both of which are designed as an elongated outer strip 12a and inner strip 13a with an outer hook 12b or inner hook 13b. They are slightly bent away from each other, so that a frame element 20 (not shown), which has suitably shaped cavities or strips 22, can be easily clipped or pushed into one another. Such a frame element 20 is then also guided by an outer guide lug 14 and an inner guide lug 16 and thus further stabilized, resulting in a firm connection with the frame element 20. The outer guide lug 14 is arranged in a first plane E14, which - in relation to the intended installation position - lies below a second plane E16 on which the inner guide lug 16 is arranged. The frame element 20 can thus be brought together with the connecting element, the frame element 20 of the inner guide nose 16 being slightly inclined. This further facilitates the connection. Since the connecting element is shown in a state not connected to the frame element 20, the sealing element 11 is unloaded and fully deployed. An extension point 11c is as far away from the connecting element or holding element 15 as possible, and lies on the third plane E11.

Das Dichtungselement 11 ist als Hohlprofil ausgebildet, welches einen Hohlraum 11a, sowie einen Gurt 11b aufweist, wobei dieser in eine Haltevorrichtung 15 eingreift und so das Dichtungselement 11 in der Haltevorrichtung 15 befestigt. Diese Ausführungsform ist besonders vorteilhaft, da so ohne Klebstoff auf formschlüssige Weise eine dichte Verbindung hergestellt werden kann und das Dichtungselement 11 jederzeit ausgewechselt werden kann. Die Größe des Dichtungselements 11 sowie der Haltevorrichtung 15 sind so dimensioniert, dass bei der Zusammenführung von Verbindungselement 1 und Rahmenelement 20 das Dichtungselement 11 zusammengedrückt wird, jedoch genug Platz bleibt, um bei thermisch bedingten Zusammenziehen der Teile noch weiter zusammengedrückt werden zu können. Gleichzeitig sollte aber auch bei thermisch bedingter Ausdehnung der Teile das Dichtungselement 11 trotzdem noch eine dichte Verbindung mit dem Rahmenelement 20 aufweisen. Bei Zusammenbau ist das Dichtungselement 11 einfach in die Haltevorrichtung 15 hineinsteckbar oder hineinschiebbar. Des Weiteren weist das Verbindungselement 1 ein -in Fig. 2 nicht dargestelltes-Verstärkungselement 17 auf, welches als metallisches, gebogenes Profil ausgeführt ist. Dieses Profil kann sich über die gesamte Länge der Verbindung erstrecken, kann aber auch nur abschnittsweise in Form von mehreren aneinander gereihten Profilen vorliegen.The sealing element 11 is designed as a hollow profile which has a cavity 11a and a belt 11b, which engages in a holding device 15 and thus fastens the sealing element 11 in the holding device 15. This embodiment is particularly advantageous since a tight connection can be made in a positive manner without adhesive and the sealing element 11 can be replaced at any time. The size of the sealing element 11 and the holding device 15 are dimensioned such that when the connecting element 1 and the frame element 20 are brought together, the sealing element 11 is compressed, but there is still enough space to be able to be compressed even further when the parts are thermally contracted. At the same time, however, the sealing element 11 should still have a tight connection to the frame element 20 even when the parts are thermally expanded. When assembled, the sealing element 11 can simply be inserted or pushed into the holding device 15. Furthermore, the connecting element 1 has an -in Fig. 2 not shown-reinforcing element 17, which is designed as a metallic, curved profile. This profile can extend over the entire length of the connection, but can also be present only in sections in the form of a plurality of profiles arranged in a row.

In Fig. 3 wird das gleiche Verbindungselement 1 wie in Fig. 2 dargestellt, jedoch ist es bereits mit dem Rahmenelement 20 verbunden. Das Rahmenelement 20 weist Leisten 22 auf, welche in die äußere Halteleiste 12 und die innere Halteleiste 13 eingreifen und damit eine formschlüssige Verbindung eingehen. Das Dichtungselement 11 ist zusammengedrückt anliegend an einer Verbindungsfläche 21 des Rahmenelements 20, wodurch eine dichte Verbindung zwischen dem Verbindungselement 1 und dem Rahmenelement 20 hergestellt wird. Die äußere Führungsnase 14 und innere Führungsnase 16 liegen direkt am Rahmenelement 20 an. Die Verbindungsfläche 21 liegt auf einer vierten Ebene E21, welche oberhalb der dritten Ebene E11 liegt, wodurch die dichte Verbindung sichergestellt ist.In Fig. 3 the same connecting element 1 as in Fig. 2 shown, but it is already connected to the frame element 20. The frame element 20 has strips 22 which engage in the outer holding strip 12 and the inner holding strip 13 and thus form a positive connection. The sealing element 11 is pressed against a connecting surface 21 of the frame element 20, whereby a tight connection between the connecting element 1 and the frame element 20 is produced. The outer guide lug 14 and inner guide lug 16 bear directly on the frame element 20. The connecting surface 21 lies on a fourth level E21, which lies above the third level E11, which ensures the tight connection.
