- a groove can be provided in the winding shaft for this purpose, which roughly corresponds to the contour of the hook-shaped element and makes it possible to provide a connection between the hook-shaped element and the groove.
- the spring element or the second connecting element is mounted displaceably in the groove of the winding shaft.
- the displaceable mounting can in particular relate to an extension in the direction of the spring element in the operational alignment state.

- the hook-shaped element is arranged on an end face of the spring element in the second connecting section.
- the spring element according to the invention can preferably be provided as a one-part or multi-part leaf spring.
- a contour of the spring element can be shaped into a hook element, for example by a stamping process. This allows the end of the spring element in the second connecting section to be fixed directly in a recess or groove in the winding shaft.

- the spring element according to the invention can have any number of partial sections aligned parallel to one another in its central part. These several parallel sections can mutually stabilize their rigidity in the case of a linear alignment of the spring element between the roller shutter curtain and the winding shaft. This can have a positive influence in particular with regard to the service life of the spring element.
- the free space formed between the sections aligned in parallel can be produced, for example, by punching.

A lateral tilting of the spring element on the surface of the winding shaft relative to the direction of extension of the spring element can thereby be counteracted.
- the end of the spring element which carries the second connecting element is angled with respect to the central part of the spring element.
- the second connecting section can be excluded from the recurring curving and straightening of the central part of the spring element when the roller shutter curtain is rolled up and unrolled from the winding shaft; this can be of particular advantage with regard to the longevity of the connection between winding shaft and spring element.
- an extension is provided on the side of the spring element which carries the second connecting section, which extension provides an expanded contact surface of the spring element on the winding shaft. Accordingly, not only a flat support of the spring element, preferably across its width, can promote stabilization of the position of the spring element on the winding shaft, but also (or alternatively) an increased contact surface in the longitudinal direction of the spring element, for example over the connection area between winding shaft and spring element in the extension direction of the spring element going out. Accordingly, the second connecting portion between the extension and a central part of the spring element can be arranged. The extension preferably also rests flat on the surface of the winding shaft and thereby additionally increases the stability of the spring element.
- the stabilization here also relates to a relative displacement of the spring element itself with respect to the winding shaft, i.e. for example accidentally folding over the spring element on the winding shaft, whereby the top of the spring element would become the contact side with the winding shaft.
- a folding over can counteract a torque-increasing stiffening of the spring element between the winding shaft and the roller shutter curtain in an unfavorable manner.
- the extension extends in a longitudinal direction of the spring element beyond the second connecting section at the end.
- the extension can be in one piece or in several parts, the extension of the spring element providing a support surface thereof beyond the second connecting section or the second connecting element.
- extension is designed in the form of a band / loop and with its free end encompasses the winding shaft.
- the extension can in this case completely or partially enclose the winding shaft on the circumferential side and additionally be fixed on the winding shaft. As a result, the alignment of the spring element with respect to the winding shaft is additionally stabilized overall.
- the extension extends from the end of the spring element which carries the second connecting element around the winding shaft in a rolling direction of the same.
- the central part of the spring element is arranged in its linear state tangentially to the winding shaft in a cross-sectional view.
- the band-shaped / loop-shaped extension of the spring element can Here, starting from the second connecting section, extend in the same direction as the central part of the spring element, the extension being arranged against the linearly aligned central part of the spring element further around the outer circumference of the winding shaft.
- a free end of the extension can be fixed on the shaft, preferably engages in a fixing manner in a groove on the winding shaft.
- the free end of the extension is the free end of the band-shaped / loop-shaped extension
- the free end of the extension can have a further connection area, for example a hook-shaped element, which engages in a corresponding groove or receptacle in the winding shaft can.
- the extension with respect to the winding shaft is secured with its one end via the second connecting element and with its other end via the connection area at its free end opposite the winding shaft.
- the spring element can be fixed in a particularly reliable manner with respect to the winding shaft.
- the band-shaped / loop-shaped extension is particularly preferably fastened to or connected to the spring element in a section which lies between the second connecting element and the central part of the spring element. In this way, a folding of the spring element on the winding shaft around the second connecting element as the fulcrum is counteracted in a particularly reliable manner.
- Figure 1 shows a commercially available connection between a roller shutter 3 and a winding shaft 2 of a roller shutter arrangement, by means of a connecting band 4, which is present loosely between the winding shaft 2 and the roller shutter 3 in the unrolled state of the roller shutter 3.

- the spring element 5 can therefore extend beyond the connection of the same with the central shaft 2 in the longitudinal direction extend.
- the extensions 5a can counteract a folding over of the spring element with respect to the winding shaft 2, whereby a flat contact of the second connection area of the spring element 5 on the winding shaft 2 can be supported. This can in particular be beneficial for the stiffening of the spring element 5 between the winding shaft 2 and the roller shutter curtain 6 in the linearly aligned state of the spring element 5.
- Figure 5 shows an enlarged view of a section of the spring element 5 according to FIG Figure 4 , in particular a part of the central part and the second connection area with the second connection element and the extensions 5a.
- two extensions 5a are preferably arranged, one to the right and one to the left of the second connecting element. Since the spring element is preferably basically aligned flat, the location information with regard to the extensions 5a is to be understood within the expansion plane of the spring element.

Description
Die vorliegende Erfindung betrifft eine Rollladenanordnung mit einem Rollladenpanzer und einer Wickelwelle für den Rollladenpanzer, welche über ein Federelement miteinander verbunden sind, gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a roller shutter arrangement with a roller shutter curtain and a winding shaft for the roller shutter curtain, which are connected to one another via a spring element, according to the preamble of
Bei einer solchen Rollladenanordnung weist das Federelement zumindest 2 endseitige Verbindungsabschnitte und einen Mittelteil auf, wobei ein erstes Verbindungselement in dem ersten Verbindungsabschnitt zur Verbindung des Federelements mit dem Rollladenpanzer vorgesehen ist und ein zweites Verbindungselement in dem zweiten Verbindungsabschnitt zur Verbindung des Federelements mit der Wickelwelle angeordnet ist.In such a roller shutter arrangement, the spring element has at least 2 end connection sections and a central part, a first connection element being provided in the first connection section for connecting the spring element to the roller shutter curtain and a second connection element being arranged in the second connection section for connecting the spring element to the winding shaft .
Aus dem Stand der Technik sind motorisierte Rollladenanordnungen bekannt, bei denen in einer Schließposition des Rollladenpanzers die Wickelwelle automatisch zum Stehen kommt.Motorized roller shutter arrangements are known from the prior art, in which the winding shaft automatically comes to a standstill in a closed position of the roller shutter curtain.
Eine Endposition des Rollladenpanzers, in welcher dieser vollständig ausgefahren ist, wird traditionell über die Anzahl der Drehungen der Wickelwelle erfasst.An end position of the roller shutter curtain, in which it is fully extended, is traditionally recorded via the number of rotations of the winding shaft.
Dies kann bei langfristiger Nutzung zu einer Verstellung und Ungenauigkeiten beim maximalen Abrollen des Rollladenpanzers führen.In the event of long-term use, this can lead to an adjustment and inaccuracies when the roller shutter curtain unrolls as much as possible.
In diesem Zusammenhang stellt sich die vorliegende Erfindung die Aufgabe, eine Rollladenanordnung bereitzustellen, welche die mechanischen Voraussetzungen erfüllt, den vollständigen Schließzustand des Rollladenpanzers feststellen zu können.In this context, the present invention has the object of providing a roller shutter arrangement which meets the mechanical requirements of being able to determine the fully closed state of the roller shutter curtain.
Die Aufgabe wird nach der vorliegenden Erfindung durch eine Rollladenanordnung mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst.The object is achieved according to the present invention by a roller shutter arrangement having the characterizing features of
Diese sind, dass das Federelement bei aufgerolltem Rollladenpanzer reversibel um eine Außenkontur der Wickelwelle biegbar ist, dass Federelement bei abgerollten Rollladenpanzer zwischen Rollladenpanzer und Wickelwendel zumindest in dem Mittelteil linear ausgerichtet ist und einer weiteren Rotation der Wickelwelle in einer Abrollrichtung des Rollladenpanzer versteift als Widerstand entgegensteht.These are that the spring element is reversibly bendable around an outer contour of the winding shaft when the roller shutter curtain is rolled up, that the spring element is linearly aligned between the roller shutter curtain and the winding coil at least in the middle part when the roller shutter curtain is unrolled and that it is stiffened as a resistance to further rotation of the winding shaft in an unrolling direction of the roller shutter curtain.
Hierdurch wird im abgerollten Zustand des Rollladenpanzers der Wickelwelle durch die lineare steife Ausrichtung des Federelements ein schlagartig erhöhter Drehmomentwiderstand entgegengesetzt, welcher durch entsprechende Einrichtungen, wie beispielsweise eine Drehmoment Sensoreinrichtung, detektierbar ist.As a result, in the unrolled state of the roller shutter curtain of the winding shaft, the linear stiff alignment of the spring element opposes a sudden increase in torque resistance, which can be detected by appropriate devices, such as a torque sensor device.
Die mechanischen Voraussetzungen für die Feststellung einer Endposition des Rollladenpanzers wird somit durch das erfindungsgemäße Federelement bereitgestellt.The mechanical prerequisites for determining an end position of the roller shutter curtain are thus provided by the spring element according to the invention.
Man erkennt, dass die Erfindung zumindest dann verwirklicht ist, wenn zwischen Wickelwelle und Rollladenpanzer ein Federelement bereitgestellt ist, welches im abgewickelten Zustand des Rollladenpanzers zwischen Rollladenpanzer und Wickelwelle linear ausgerichtet vorliegt und einer weiteren Drehbewegung der Wickelwelle in Abrollrichtung einen Widerstand entgegenstellt.It can be seen that the invention is implemented at least when a spring element is provided between the winding shaft and the roller shutter, which is linearly aligned between the roller shutter and the winding shaft in the unwound state of the roller shutter and opposes a further rotational movement of the winding shaft in the unwinding direction.
Nach einer bevorzugten Weiterbildung der vorliegenden Erfindung ist es vorgesehen, dass das Federelement zumindest in dem Mittelteil und/oder in dem zweiten Verbindungsabschnitt flach ausgebildet ist.According to a preferred development of the present invention, it is provided that the spring element is designed to be flat at least in the central part and / or in the second connecting section.
Eine flache Ausbildung des Federelements kann insbesondere bezüglich der Möglichkeit, diese um die Wickelwelle aufzurollen, zuträglich sein. Zur Erhöhung der Steifigkeit des Federelements kann dieses zumindest in einem Mittelteil eine in einer Querschnittsansicht gebogene Form aufweisen, wie sie auch von bistabilen Elementen bekannt ist.A flat design of the spring element can be beneficial, in particular with regard to the possibility of rolling it up around the winding shaft. To increase the rigidity of the spring element, it can have a curved shape in a cross-sectional view, at least in a central part, as is also known from bistable elements.
Eine flache Ausbildung des Federelements kann auch eine flächige Auflagefläche zwischen zweitem Verbindungsabschnitt und Wickelwelle bereitstellen.A flat design of the spring element can also provide a flat contact surface between the second connecting section and the winding shaft.
Eine zweckmäßige Weiterbildung der vorliegenden Erfindung kann darin bestehen, dass die Kontur des zweiten Verbindungsbereichs einer Außenkontur der Wickelwelle nachempfunden ist. Eine Wickelwelle für einen Rollladenpanzer kann eine runde oder eine mehreckige Form im Querschnitt aufweisen. Insbesondere für eine flächige Auflage des Federelements auf der Wickelwelle kann zunächst ein Teil des zweiten Verbindungsabschnitt eine Runde beziehungsweise abgewinkelte Form, die der Außenkontur der Wickelwelle im Kontaktbereich mit dem zweiten Verbindungsabschnitt entspricht, aufweisen.An expedient development of the present invention can consist in that the contour of the second connection area is modeled on an outer contour of the winding shaft. A winding shaft for a roller shutter curtain can have a round or polygonal shape in cross section. In particular for a flat support of the spring element on the winding shaft, part of the second connecting section can initially have a round or angled shape that corresponds to the outer contour of the winding shaft in the contact area with the second connecting section.
Nach einer bevorzugten Weiterbildung der vorliegenden Erfindung ist es vorgesehen, dass das zweite Verbindungselement als hakenförmiges Element für einen Eingriff in eine Nut an der Wickelwelle ausgebildet ist. Zweckmäßigerweise kann die Verbindung zwischen Federelement und Wickelwelle reversibel sein. Dafür kann auf eine Vernietung oder Verschweißung des Federelements mit der Wickelwelle verzichtet werden.According to a preferred development of the present invention, it is provided that the second connecting element is designed as a hook-shaped element for engagement in a groove on the winding shaft. The connection between the spring element and the winding shaft can expediently be reversible. For this, riveting or welding of the spring element to the winding shaft can be dispensed with.
Besonders bevorzugt wird ein Bereich des Federelements mit der Wickelwelle lösbar verhakt, wodurch ein leichter Austausch des Federelements, insbesondere werkzeugfrei, ermöglicht ist. Dafür kann eine Nut in der Wickelwelle vorgesehen sein, welche der Kontur nach in etwa dem hakenförmigen Element entspricht und es ermöglicht, eine Verbindung zwischen hakenförmigem Element und Nut bereitzustellen.Particularly preferably, a region of the spring element is releasably hooked to the winding shaft, as a result of which the spring element can be easily exchanged, in particular without tools. A groove can be provided in the winding shaft for this purpose, which roughly corresponds to the contour of the hook-shaped element and makes it possible to provide a connection between the hook-shaped element and the groove.
Nach einer zweckmäßigen Weiterbildung der vorliegenden Erfindung ist es vorgesehen, dass das Federelement beziehungsweise das zweite Verbindungselement in der Nut der Wickelwelle verschieblich gelagert ist. Die verschiebliche Lagerung kann sich insbesondere auf eine Erstreckung Richtung der des Federelements im betriebsgemäßen Ausrichtungszustand beziehen. Somit kann zwar das Federelement in der Nut der Wickelwelle festgelegt sein, also aus dieser in betriebsgemäße Ausrichtung des Federelements gegenüber der Wickelwelle an dieser festgelegt sein, jedoch in Erstreckungsrichtung des Federelements ein gewisses Spiel über die Länge der Nut aufweisen. Bevorzugt ist das Federelement als längliche Verbindung zwischen Rollladenpanzer und Wickelwelle ausgebildet.According to an expedient development of the present invention, it is provided that the spring element or the second connecting element is mounted displaceably in the groove of the winding shaft. The displaceable mounting can in particular relate to an extension in the direction of the spring element in the operational alignment state. Thus, although the spring element can be fixed in the groove of the winding shaft, that is to say it can be fixed therefrom in operational alignment of the spring element with respect to the winding shaft, it can, however, have a certain amount of play over the length of the groove in the direction of extension of the spring element. The spring element is preferably designed as an elongated connection between the roller shutter curtain and the winding shaft.
Zweckmäßigerweise ist es vorgesehen, dass das hakenförmige Element an einer Stirnseite des Federelements in dem zweiten Verbindungsabschnitt angeordnet ist. Bevorzugt kann das erfindungsgemäße Federelement als einteilige oder mehrteilige Blattfeder vorgesehen sein. An dessen Kopfende im zweiten Verbindungsabschnitt kann eine Kontur des Federelements, beispielsweise durch ein Stanzverfahren, zu einem Hakenelement geformt sein. Dadurch lässt sich das Ende des Federelements im zweiten Verbindungsabschnitt direkt in einer Ausnehmung beziehungsweise Nut der Wickelwelle festlegen.It is expediently provided that the hook-shaped element is arranged on an end face of the spring element in the second connecting section. The spring element according to the invention can preferably be provided as a one-part or multi-part leaf spring. At its head end in the second connecting section, a contour of the spring element can be shaped into a hook element, for example by a stamping process. This allows the end of the spring element in the second connecting section to be fixed directly in a recess or groove in the winding shaft.
Zweckmäßigerweise kann es vorgesehen sein, dass das hakenförmige Element als Doppelhaken ausgebildet ist, dessen Hakenelemente in zwei gegenläufige Richtungen ausgerichtet sind. Für eine besonders zuverlässige Festlegung des Federelements an der Wickelwelle kann ein Doppelhaken eine zuverlässige Verbindung zwischen Federelement und Wickelwelle bereitstellen, wodurch das Federelement in zwei gegenläufigen Richtungen an der Nut beziehungsweise Ausnehmung stabilisiert beziehungsweise festgelegt ist.It can expediently be provided that the hook-shaped element is designed as a double hook, the hook elements of which are oriented in two opposite directions. For a particularly reliable fixing of the spring element on the winding shaft, a double hook can provide a reliable connection between the spring element and the winding shaft, whereby the spring element is stabilized or fixed in two opposite directions on the groove or recess.
Besonders bevorzugt ist es vorgesehen, dass die Hakenelemente im Abstand zueinander und/oder deren Breite die Maße der Nut an der Wickelwelle nicht überschreiten. Die begrenzte Bemaßung des zweiten Verbindungselements beziehungsweise der Hakenelemente erlauben ein einfaches Einführen der selbigen in die Nut an der Wickelwelle. Das Einführen kann beispielsweise in einem 90° Winkel relativ zur betriebsgemäßen Ausrichtung des Federelements gegenüber der Wickelwelle erfolgen. Durch anschließendes Ausrichten des Federelements gegenüber der Wickelwelle werden die, bevorzugt passgenauen, Hakenelemente in ihrer Ausrichtung gegenüber der Nut gedreht, wodurch diese die Nut hintergreifen und dadurch das Federelement an der Nut festlegen können.It is particularly preferred that the spacing between the hook elements and / or their width do not exceed the dimensions of the groove on the winding shaft. The limited dimensions of the second connecting element or the hook elements allow the same to be easily inserted into the groove on the winding shaft. The introduction can take place, for example, at a 90 ° angle relative to the operational alignment of the spring element with respect to the winding shaft. By subsequently aligning the spring element with respect to the winding shaft, the, preferably precisely fitting, hook elements are rotated in their alignment with respect to the groove, as a result of which they engage behind the groove and thereby fix the spring element on the groove.
Zweckmäßigerweise ist es vorgesehen, dass der Mittelteil des Federelements mindestens zweiteilig ausgebildet ist und mindestens 2 zueinander parallele Abschnitte aufweist, welches sich zwischen dem ersten und dem zweiten Verbindungsabschnitt erstrecken.It is expediently provided that the middle part of the spring element is designed in at least two parts and has at least 2 mutually parallel sections which extend between the first and the second connecting section.
Grundsätzlich kann das erfindungsgemäße Federelement eine beliebige Anzahl von parallel zueinander ausgerichteten Teilabschnitten in seinem Mittelteil aufweisen. Diese mehreren parallelen Abschnitte können sich gegenseitig hinsichtlich ihrer Steifigkeit bei einer linearen Ausrichtung des Federelements zwischen Rollladenpanzer und Wickelwelle stabilisieren. Dies kann insbesondere hinsichtlich der Lebensdauer des Federelements einen positiven Einfluss haben.In principle, the spring element according to the invention can have any number of partial sections aligned parallel to one another in its central part. These several parallel sections can mutually stabilize their rigidity in the case of a linear alignment of the spring element between the roller shutter curtain and the winding shaft. This can have a positive influence in particular with regard to the service life of the spring element.
Der zwischen den parallel ausgerichteten Abschnitten gebildete Freiraum kann beispielsweise durch Stanzen erzeugt werden. Nach einer vorteilhaften Weiterbildung der vorliegenden Erfindung kann das Material des Federelements, welches beim Bilden der Freiräume zwischen den parallel ausgerichteten Abschnitten entfernt wird, in zumindest einem Bereich weiterhin mit dem Federelement verbunden sein. Dieses Material kann beispielsweise zur Befestigung des Federelements an der Wickelwelle verwendet werden. Eine Befestigung des Federelements an der Wickelwelle kann beispielsweise in Form einer offenen Schlaufe erfolgen, dessen freies Ende an der Wickelwelle festlegbar ist. Die Festlegung kann hierbei in ähnlicher Weise erfolgen wie die Verbindung zwischen dem zweiten Verbindungselement und der Wickelwelle also beispielsweise durch eine Nut-Haken Verbindung.The free space formed between the sections aligned in parallel can be produced, for example, by punching. According to an advantageous development of the present invention, the material of the spring element, which is removed when the free spaces are formed between the parallel-aligned sections, can still be connected to the spring element in at least one area. This material can be used, for example, to attach the spring element to the winding shaft. The spring element can be attached to the winding shaft, for example, in the form of an open loop, the free end of which is attached to the Winding shaft is fixable. The fixing can take place in a similar way to the connection between the second connecting element and the winding shaft, for example by means of a groove-hook connection.
Zweckmäßigerweise ist es vorgesehen, dass das freie Ende des Federelements, welches das zweite Verbindungselement trägt, in seiner Außenkontur an die Wickelwelle angepasst ist.It is expediently provided that the free end of the spring element, which carries the second connecting element, is adapted in its outer contour to the winding shaft.
Besonders bevorzugt ist es vorgesehen, dass der zweite Verbindungsabschnitt zumindest teilweise flach auf der Wickelwelle aufliegt. Dies kann insbesondere bezüglich einer seitlichen Stabilisierung der Verbindung zwischen Federelement und Wickelwelle zuträglich sein. Ein seitliches Verkippen des Federelements auf der Oberfläche der Wickelwelle zur Erstreckungsrichtung des Federelements kann dadurch entgegengewirkt sein.It is particularly preferably provided that the second connecting section rests at least partially flat on the winding shaft. This can be beneficial in particular with regard to a lateral stabilization of the connection between the spring element and the winding shaft. A lateral tilting of the spring element on the surface of the winding shaft relative to the direction of extension of the spring element can thereby be counteracted.
Vorteilhafterweise ist es vorgesehen, dass das Ende des Federelements, welches das zweite Verbindungselement trägt, gegenüber dem Mittelteil des Federelements abgewinkelt ist. Durch diesen vorgesehenen Winkel kann der zweite Verbindungsabschnitt aus dem wiederkehrenden Krümmen und Begradigen des Mittelteils des Federelements beim Aufrollen und Abrollen des Rollladenpanzers von der Wickelwelle ausgenommen werden, dies kann insbesondere hinsichtlich der Langlebigkeit der Verbindung zwischen Wickelwelle und Federelement von Vorteil sein.It is advantageously provided that the end of the spring element which carries the second connecting element is angled with respect to the central part of the spring element. With this provided angle, the second connecting section can be excluded from the recurring curving and straightening of the central part of the spring element when the roller shutter curtain is rolled up and unrolled from the winding shaft; this can be of particular advantage with regard to the longevity of the connection between winding shaft and spring element.
Zweckmäßigerweise kann es vorgesehen sein, dass an der Seite des Federelements, welches den zweiten Verbindungsabschnitt trägt, eine Verlängerung vorgesehen ist, welche eine erweiterte Auflagefläche des Federelements an der Wickelwelle bereitstellt. Demnach kann nicht nur eine flächige Auflage des Federelements, vorzugsweise über seine Breite eine Stabilisierung der Lage des Federelements an der Wickelwelle begünstigen, sondern auch (oder alternativ) eine erhöhte Auflagefläche in Längsrichtung des Federelements beispielsweise über den Verbindungsbereich zwischen Wickelwelle und Federelement in Erstreckungsrichtung des Federelements hinausgehend. Demnach kann der zweite Verbindungsabschnitt zwischen der Verlängerung und einem Mittelteil des Federelements angeordnet sein. Bevorzugt liegt die Verlängerung hierbei ebenfalls flächig auf der Oberfläche der Wickelwelle auf und erhöht dadurch zusätzlich die Stabilität des Federelements. Die Stabilisierung bezieht sich hierbei ebenfalls auf eine relative Verlagerung des Federelements an sich gegenüber der Wickelwelle, also beispielsweise einem versehentlichen Umklappen des Federelements an der Wickelwelle, wodurch die Oberseite des Federelements zur Kontaktseite mit der Wickelwelle werden würde. Ein solches Umklappen kann einer drehmomenterhöhenden Versteifung des Federelements zwischen Wickelwelle und Rollladenpanzer in ungünstiger Weise entgegenstehen.It can expediently be provided that an extension is provided on the side of the spring element which carries the second connecting section, which extension provides an expanded contact surface of the spring element on the winding shaft. Accordingly, not only a flat support of the spring element, preferably across its width, can promote stabilization of the position of the spring element on the winding shaft, but also (or alternatively) an increased contact surface in the longitudinal direction of the spring element, for example over the connection area between winding shaft and spring element in the extension direction of the spring element going out. Accordingly, the second connecting portion between the extension and a central part of the spring element can be arranged. The extension preferably also rests flat on the surface of the winding shaft and thereby additionally increases the stability of the spring element. The stabilization here also relates to a relative displacement of the spring element itself with respect to the winding shaft, i.e. for example accidentally folding over the spring element on the winding shaft, whereby the top of the spring element would become the contact side with the winding shaft. Such a folding over can counteract a torque-increasing stiffening of the spring element between the winding shaft and the roller shutter curtain in an unfavorable manner.
Nach einer besonders bevorzugten Ausführungsform der vorliegenden Erfindung ist es vorgesehen, dass sich die Verlängerung in einer Längsrichtung des Federelements über den zweiten Verbindungsabschnitt hinaus endseitig erstreckt. Die Verlängerung kann einteilig oder mehrteilig sein, wobei die Verlängerung des Federelements eine Auflagefläche desselbigen über den zweiten Verbindungsabschnitt beziehungsweise das zweite Verbindungselement hinaus bereitstellt.According to a particularly preferred embodiment of the present invention, it is provided that the extension extends in a longitudinal direction of the spring element beyond the second connecting section at the end. The extension can be in one piece or in several parts, the extension of the spring element providing a support surface thereof beyond the second connecting section or the second connecting element.
Eine weitere besonders bevorzugte Ausführungsform der vorliegenden Erfindung kann darin gesehen werden, dass die Verlängerung bandförmig/schlaufenförmig ausgebildet ist und mit seinem freien Ende die Wickelwelle umfasst. Die Verlängerung kann die Wickelwelle hierbei ganz oder teilweise umfangseitig umschließen und an der Wickelwelle zusätzlich festgelegt sein. Hierdurch wird insgesamt die Ausrichtung des Federelements gegenüber der Wickelwelle zusätzlich stabilisiert.Another particularly preferred embodiment of the present invention can be seen in the fact that the extension is designed in the form of a band / loop and with its free end encompasses the winding shaft. The extension can in this case completely or partially enclose the winding shaft on the circumferential side and additionally be fixed on the winding shaft. As a result, the alignment of the spring element with respect to the winding shaft is additionally stabilized overall.
Zweckmäßigerweise ist es vorgesehen, dass sich die Verlängerung von dem Ende des Federelements, welches das zweite Verbindungselement trägt, um die Wickelwelle in einer Abrollrichtung derselbigen erstreckt.It is expediently provided that the extension extends from the end of the spring element which carries the second connecting element around the winding shaft in a rolling direction of the same.
Vorzugsweise ist es vorgesehen, dass der Mittelteil des Federelements in seinem linearen Zustand tangential zur Wickelwelle in einer Querschnittsansicht angeordnet ist. Die bandförmige/schlaufenförmige Verlängerung des Federelements kann sich hierbei ausgehend vom zweiten Verbindungsabschnitt in derselben Richtung erstrecken, wie der Mittelteil des Federelements, wobei die Verlängerung entgegen dem linear ausgerichteten Mittelteil des Federelements weiter um den Außenumfang der Wickelwelle herum angeordnet ist.It is preferably provided that the central part of the spring element is arranged in its linear state tangentially to the winding shaft in a cross-sectional view. The band-shaped / loop-shaped extension of the spring element can Here, starting from the second connecting section, extend in the same direction as the central part of the spring element, the extension being arranged against the linearly aligned central part of the spring element further around the outer circumference of the winding shaft.
Zweckmäßigerweise ist es vorgesehen, dass ein freies Ende der Verlängerung an der Welle festlegbar ist, vorzugsweise in eine Nut an der Wickelwelle fixierend eingreift.It is expediently provided that a free end of the extension can be fixed on the shaft, preferably engages in a fixing manner in a groove on the winding shaft.
Bevorzugt, wenn es sich bei dem freien Ende der Verlängerung um das freie Ende der bandförmige/schlaufenförmige Verlängerung handelt, kann das freie Ende der Verlängerung einen weiteren Verbindungsbereich, beispielsweise ein hakenförmiges Element, aufweisen, welches in eine entsprechende Nut oder Aufnahme in der Wickelwelle eingreifen kann. Hierdurch ist die Verlängerung gegenüber der Wickelwelle mit ihrem einem Ende über das zweite Verbindungselement und mit ihrem anderen Ende über den Verbindungsbereich an seinem freien Ende gegenüber der Wickelwelle gesichert. Hierdurch kann das Federelement in besonders zuverlässiger Weise gegenüber der Wickelwelle festgelegt sein.Preferably, if the free end of the extension is the free end of the band-shaped / loop-shaped extension, the free end of the extension can have a further connection area, for example a hook-shaped element, which engages in a corresponding groove or receptacle in the winding shaft can. As a result, the extension with respect to the winding shaft is secured with its one end via the second connecting element and with its other end via the connection area at its free end opposite the winding shaft. As a result, the spring element can be fixed in a particularly reliable manner with respect to the winding shaft.
Besonders bevorzugt ist die bandförmige/schlaufenförmige Verlängerung in einem Abschnitt an dem Federelement befestigt oder mit diesem verbunden, welcher zwischen dem zweiten Verbindungselement und dem Mittelteil des Federelements liegt. Hierdurch wird in besonders zuverlässiger Weise einem Umlegen des Federelements an der Wickelwelle um das zweite Verbindungselement als Drehpunkt entgegengewirkt.The band-shaped / loop-shaped extension is particularly preferably fastened to or connected to the spring element in a section which lies between the second connecting element and the central part of the spring element. In this way, a folding of the spring element on the winding shaft around the second connecting element as the fulcrum is counteracted in a particularly reliable manner.
