Description

I. AnwendungsgebietI. Field of application

Die vorliegende Erfindung betrifft ein Rahmenelement für einen Spannrahmen zum Aufspannen eines flächigen Materials wie beispielsweise einer in der Kunstmalerei verwendeten Leinwand.The present invention relates to a frame member for a tenter for mounting a sheet material such as a canvas used in art painting.

II. Technischer HintergrundII. Technical background

Ein Spannrahmen zum Aufspannen eines flächigen Materials wie einer Leinwand ist insbesondere aus der DE 103 12 637 A1 bekannt. In der dortigen Fig. 6 ist ein Rahmenelement 11 mit einer Fixieraussparung 81 und einer Nut 111 gezeigt. Die Leinwand 5 wird mit Hilfe des Einsteckteils 82 des Stützelements 91 reibschlüssig in der Fixieraussparung 81 fixiert. Wie in Absatz [0079] offenbart können bei dem bekannten Spannrahmen das Stützelement 91 und das Einspannteil 92 abweichend von Fig. 6 auch als einheitliches Bauteil integral miteinander verbunden sein. Dieses einheitliche Bauteil 91, 92 wirkt dann wie eine von dem Rahmenelement 11 separat vorgesehene Feder und drückt die Leinwand 5 in die Nut 111. A clamping frame for mounting a sheet material such as a canvas is in particular from DE 103 12 637 A1 known. In the local Fig. 6 For example, a frame member 11 having a fixing recess 81 and a groove 111 is shown. The canvas 5 is fixed by means of the insertion part 82 of the support member 91 frictionally engaged in the fixing recess 81 . As disclosed in paragraph [0079] , in the known stenter frame, the support member 91 and the chuck member 92 may differ from FIG Fig. 6 also be integrally connected as a single component. This unitary component 91, 92 then acts like a spring provided separately from the frame element 11 and presses the canvas 5 into the groove 111.

Besonders vorteilhaft ist es bei der Variante gemäß Fig. 6 , dass das Fixieren der Leinwand 5 an einem Ende des in der Art einer Feder wirkenden Stützelements 91 und das Spannen der Leinwand 5 an dem anderen Ende des in der Art einer Feder wirkenden Stützelements 91 stattfindet. Dadurch wird eine erleichterte Handhabung beim Spannen und Fixieren der Leinwand 5 erreicht. Eine derartige Erleichterung ist beispielsweise bei der in Fig. 5 der DE 103 12 637 A1 gezeigten Variante nicht gegeben. Dort findet sowohl das Spannen als auch das Fixieren der Leinwand 5 mit Hilfe des Befestigungselements 6 an demselben Ende, dem oberen Ende, des Gegenhalteelements 7 statt, was zu einer komplizierteren Handhabung führt.It is particularly advantageous in the variant according to Fig. 6 in that the fixing of the screen 5 takes place at one end of the spring-type supporting member 91 and the tensioning of the screen 5 at the other end of the spring-type supporting member 91 . As a result, easier handling when clamping and fixing the screen 5 is achieved. Such a relief is for example in the in Fig. 5 of the DE 103 12 637 A1 not shown variant. There, both the tensioning and fixing of the canvas 5 by means of the fastening element 6 at the same end, the upper end of the counter-holding element 7 takes place, which leads to a more complicated handling.

Bei dem bekannten Spannrahmen gemäß Fig. 6 der DE 103 12 637 A1 ist es jedoch nachteilig, dass das Stützelement 91 und das Einspannteil 92 aus dem Rahmenelement 11 hervorstehen. Beim Tragen oder sonstigen Handhaben des bekannten mit Leinwand 5 bespannten Spannrahmens kommt es immer wieder vor, dass insbesondere das Stützelement 91 unvorsichtig berührt und dadurch gelöst wird. Dies erfordert, dass die Leinwand 5 im Bereich der gelösten Stützelemente 91 wieder gespannt und die Einsteckteile 92 der entsprechenden Stützelemente 91 wieder in die für sie vorgesehenen Fixieraussparungen des Rahmenelements 11 gesteckt werden müssen. Dieser Aufwand ist naturgemäß unerwünscht.In the known clamping frame according to Fig. 6 of the DE 103 12 637 A1 However, it is disadvantageous that the support member 91 and the chucking part 92 protrude from the frame member 11 . When wearing or other handling of the known strung with canvas 5 stretcher, it happens again and again that in particular the support member 91 carelessly touched and thereby solved. This requires that the canvas 5 again stretched in the area of the released support elements 91 and the insertion parts 92 of the corresponding support elements 91 must again be inserted into the fixing recesses of the frame element 11 provided for them. This effort is naturally undesirable.

III. Darstellung der ErfindungIII. Presentation of the invention a) Technische Aufgabea) Technical task

Es ist daher die Aufgabe der vorliegenden Erfindung, ein Rahmenelement für einen Spannrahmen zum Aufspannen eines flächigen Materials wie beispielsweise einer in der Kunstmalerei verwendeten Leinwand zu schaffen, welches gewährleistet, dass unter Beibehaltung der erleichterten Handhabung beim Spannen und Fixieren des flächigen Materials die die Spannung des flächigen Materials bewirkenden und separat von dem Rahmenelement vorgesehenen Federn nicht durch unvorsichtige Handhabung des aus mehreren Rahmenelementen zusammengesetzten Spannrahmens gelöst werden können.It is therefore an object of the present invention to provide a frame member for a clamping frame for mounting a sheet material such as a canvas used in art painting, which ensures that while maintaining the ease of handling when clamping and fixing the sheet material, the voltage of the laminar material causing and provided separately from the frame member springs can not be solved by careless handling of the composite of several frame elements clamping frame.

b) Lösung der Aufgabeb) Solution of the task

Diese Aufgabe wird mittels eines Rahmenelements mit den Merkmalen des Anspruchs 1 gelöst. Weitere Ausgestaltungen der vorliegenden Erfindung ergeben sich aus den Unteransprüchen.This object is achieved by means of a frame element with the features of claim 1 . Further embodiments of the present invention will become apparent from the dependent claims.

Erfindungsgemäß wird ein Rahmenelement für einen Spannrahmen zum Aufspannen eines flächigen Materials wie beispielsweise einer in der Kunstmalerei verwendeten Leinwand vorgeschlagen, welches einen Spannhohlraum zum Spannen des flächigen Materials und eine Fixiereinrichtung zum Fixieren des flächigen Materials an dem Rahmenelement aufweist. Dabei ist das flächige Material mittels eines Fixierendes einer separat von dem Rahmenelement vorgesehenen Feder an der Fixiereinrichtung festklemmbar. Das Fixierende der Feder wirkt derart mit der Fixiereinrichtung zusammen, dass das fixierte flächige Material mittels eines dem Fixierende gegenüberliegenden Spannendes der Feder in den Spannhohlraum vorspannbar ist. Die Fixiereinrichtung ist in dem Spannhohlraum angeordnet und der Spannhohlraum ist derart bemessen, dass die Feder samt ihrem Fixierende und ihrem Spannende vollständig in dem Spannhohlraum des Rahmenelements aufnehmbar ist.According to the invention, a frame element is proposed for a clamping frame for mounting a sheet material such as a canvas used in art painting, which has a clamping cavity for clamping the sheet material and a fixing device for fixing the sheet material to the frame member. In this case, the sheet material can be clamped to the fixing device by means of a fixing of a spring provided separately from the frame element. The fixing end of the spring interacts with the fixing device in such a way that the fixed sheet material can be prestressed into the clamping hollow space by means of a clamping end of the spring lying opposite the fixing end. The fixing device is arranged in the clamping cavity and the clamping cavity is dimensioned such that the spring together with its fixing end and its exciting part is completely receivable in the clamping cavity of the frame member.

Dadurch, dass die separate Feder vollständig in dem Spannhohlraum des Rahmenelements aufnehmbar ist, ragt sie nicht mehr aus dem Profil des Rahmenelements heraus und kann daher nicht mehr durch unvorsichtige Handhabung berührt und gelöst werden. Die Feder ist vollständig im Inneren des Profils des Rahmenelements angeordnet. Vorteilhaft ist außerdem, dass das erfindungsgemäße Rahmenelement keine elastischen Elemente oder Bereiche aufweisen muss, sondern in sich vollkommen starr ausgebildet werden kann, was die Herstellung des Rahmenelements vereinfacht. Die erforderliche Elastizität wird von der separaten Feder mitgebracht, die zum Spannen des flächigen Materials an dem Rahmenelement montiert wird.Characterized in that the separate spring is completely received in the clamping cavity of the frame member, it no longer protrudes from the profile of the frame member and therefore can not be touched and solved by careless handling. The spring is arranged completely inside the profile of the frame element. It is also advantageous that the frame element according to the invention does not have to have elastic elements or regions, but can be made completely rigid in itself, which simplifies the production of the frame element. The required elasticity is brought by the separate spring which is mounted on the frame element for tensioning the sheet material.

Das erfindungsgemäße Rahmenelement kann nicht nur zur Herstellung von Spannrahmen für den Künstlerbedarf verwendet werden, sondern überall dort, wo flächige Materialien auf Rahmen aufgespannt werden. Beispielsweise ist insbesondere die Verwendung im Rahmen des Messebaus denkbar, wo häufig zur Herstellung von Trenn- oder Präsentationswänden flächige Materialien auf Rahmen aufgezogen werden.The frame element according to the invention can be used not only for the production of stenter for the artist's needs, but everywhere, where sheet materials are clamped on frames. For example, in particular the use in the context of exhibition construction is conceivable, where often for the production of separation or presentation walls surface materials are mounted on frames.

Bei der in dem Spannhohlraum angeordneten Fixiereinrichtung kann es sich beispielsweise um eine Fixieraussparung handeln, in welche das Fixierende der Feder zum Fixieren des flächigen Materials einsetzbar ist. Dabei weist die Fixieraussparung eine Öffnung auf, durch welche hindurch sie in den verbleibenden Spannhohlraum mündet. Im Falle der Ausbildung der Fixiereinrichtung als Fixieraussparung ist die Feder samt ihrem Fixierende und ihrem Spannende vollständig in dem von der Fixieraussparung und dem verbleibenden Spannhohlraum gebildeten Raum aufnehmbar. Sie befindet sich vollständig innerhalb des Rahmenelements und steht nicht aus diesem hervor.The fixing device arranged in the clamping cavity may be, for example, a fixing recess into which the fixing end of the spring can be inserted for fixing the sheet material. In this case, the fixing recess has an opening through which it opens into the remaining clamping cavity. In the case of the formation of the fixing device as a fixing recess, the spring together with its fixing end and its exciting is completely accommodated in the space formed by the fixing recess and the remaining clamping cavity. It is completely inside the frame element and does not stand out from it.

Besonders vorteilhaft ist es, die Fixieraussparung als Drehlager zur begrenzt drehbaren Aufnahme des Fixierendes der Feder auszubilden. Dabei ist ein Anschlag bzw. eine Anschlagfläche in der Fixieraussparung angeordnet, wodurch die Drehbewegbarkeit des Fixierendes der Feder in derjenigen Drehrichtung begrenzt wird, in welche das Spannende der Feder durch Drehen des Fixierendes entgegen einer Spannrichtung zum Spannen des flächigen Materials bewegbar ist. Die Anschlagfläche kann in die Fixieraussparung hineinragen oder von einer ohnehin vorhandenen Begrenzungswandung der Fixieraussparung gebildet werden.To form the fixing recess as a pivot bearing for limited rotatable recording of the fixing of the spring is particularly advantageous. In this case, a stop or a stop surface is arranged in the fixing recess, whereby the rotational movement of the fixing of the spring is limited in that direction in which the exciting of the spring by rotating the fixing end against a clamping direction for clamping the sheet material is movable. The abutment surface may protrude into the fixing recess or be formed by an already existing boundary wall of the Fixieraussparung.

Das gespannte flächige Material trachtet danach, die Feder entgegen der vorgenannten Spannrichtung um ihr Fixierende zu drehen. Eine solche Drehung ist nur solange möglich, bis das Fixierende von der Anschlagfläche gestoppt wird. Ab diesem Moment wird die Feder aufgrund ihrer Eigenelastizität durch die Vorspannung des flächigen Materials gebogen. Sobald sich die Rückstellkraft der Feder im Gleichgewicht mit der von der Vorspannung des flächigen Materials auf die Feder ausgeübten Kraft befindet, ist ein stabiler Zustand erreicht und die von der Feder erzeugte Rückstellkraft hält das flächige Material dauerhaft in Spannung. Dabei wird es in den Spannhohlraum des Rahmenelements hereingezogen.The tensioned sheet material seeks to rotate the spring against the aforementioned tensioning direction around its fixation. Such a rotation is only possible until the fixing end of the stop surface is stopped. From this moment, the spring is bent due to its inherent elasticity by the bias of the sheet material. As soon as the restoring force the spring is in equilibrium with the force exerted by the bias of the sheet material on the spring force, a stable state is achieved and the restoring force generated by the spring keeps the sheet material permanently in tension. It is pulled into the clamping cavity of the frame member.

Vorteilhaft ist es, die Öffnung der Fixieraussparung mit einer lichten Öffnungsweite zu versehen, die kleiner als eine Breite des Fixierendes der Feder ist. Eine Feder mit in Richtung ihrer Breite elastisch ausgebildetem Fixierende ist dann formschlüssig in die Fixieraussparung einrastbar. Beim Einführen in die Fixieraussparung verjüngt sich das Fixierende zunächst auf die lichte Öffnungsweite der Öffnung bevor es sich nach dem Durchdringen der Öffnung wieder aufweitet.It is advantageous to provide the opening of the Fixieraussparung with a clear opening width which is smaller than a width of the fixing of the spring. A spring with in the direction of its width elastically formed fixing is then positively locked in the Fixieraussparung. When inserted into the fixing recess, the fixing element initially tapers to the clear opening width of the opening before it widens again after penetration of the opening.

Zum abschnittsweisen Führen des flächigen Materials von dem Fixierende in Richtung des Spannendes der Feder kann auf einer Seite der Öffnung der Fixieraussparung eine Führungsfläche ausgebildet werden, an welcher das flächige Material abschnittsweise anliegen kann. Dabei verläuft die Führungsfläche vorzugsweise teilweise innerhalb sowie teilweise außerhalb der Fixieraussparung. Hierbei ist es vorteilhaft, die Anschlagfläche zum Begrenzen der Drehbewegbarkeit des Fixierendes der Feder in die Fixieraussparung hineinragen zu lassen und auf der Rückseite des innerhalb der Fixieraussparung verlaufenden Abschnitts der Führungsfläche anzuordnen.For partially guiding the sheet material from the fixing end in the direction of the exciting end of the spring, a guide surface can be formed on one side of the opening of the fixing recess, against which the flat material can abut in sections. In this case, the guide surface preferably extends partially within and partially outside the Fixieraussparung. In this case, it is advantageous to allow the abutment surface to project into the fixing recess for limiting the rotational movement of the fixing end of the spring and to arrange it on the rear side of the section of the guide surface extending within the fixing recess.

Die Haltekraft, welche das flächige Material in der Fixieraussparung hält, ergibt sich aus der Haftreibung, die durch die Klemmung des flächigen Materials zwischen dem Fixierende der Feder einerseits und der Innenwandung der Fixieraussparung andererseits bewirkt wird. Um einen zusätzlichen Widerstand des in der Fixieraussparung geklemmten flächigen Materials gegen ein Herausziehen aus der Fixieraussparung zu erzeugen, können an der Innenwand der Fixieraussparung Widerhaken für den Eingriff in das flächige Material angeordnet werden.The holding force which holds the sheet material in the Fixieraussparung, resulting from the static friction, which is caused by the clamping of the sheet material between the fixing end of the spring on the one hand and the inner wall of the Fixieraussparung on the other. In order to generate an additional resistance of the clamped in the Fixieraussparung sheet material against withdrawal from the Fixieraussparung, barbs for engagement in the sheet material can be arranged on the inner wall of the Fixieraussparung.

Der Querschnitt der Fixieraussparung kann verschiedene Formen annehmen. Je nachdem, welche Querschnittsgeometrie gewählt wird, kommen Federn mit entsprechend angepasster Geometrie ihrer Fixierenden zum Einsatz. Denkbar ist beispielsweise, dass der Querschnitt der Fixieraussparung im Wesentlichen eine Kreisform, im Wesentlichen die Form eines ¼-Kreisringes oder im Wesentlichen eine längliche geradlinige Form aufweist. Grundsätzlich denkbar sind auch hiervon abweichende Formen.The cross section of the fixing recess can take various forms. Depending on which cross-sectional geometry is selected, springs with appropriately adapted geometry of their fixators are used. It is conceivable, for example, that the cross section of the fixing recess substantially has a circular shape, substantially the shape of a ¼-circular ring or substantially an elongated rectilinear shape. In principle, deviating forms are also conceivable.

Als Alternative zu der Gestaltung der Fixiereinrichtung als Fixieraussparung besteht die Möglichkeit, die Fixiereinrichtung im Rahmen der vorliegenden Erfindung als in den Spannhohlraum hineinragenden Fixiervorsprung auszubilden, auf welchen das Fixierende der Feder zum Fixieren des flächigen Materials durch Verklemmen zwischen dem Fixiervorsprung und dem Fixierende aufsetzbar ist.As an alternative to the design of the fixing device as Fixieraussparung it is possible to form the fixing in the context of the present invention as projecting into the clamping cavity fixing projection on which the fixing end of the spring for fixing the sheet material by jamming between the fixing projection and the fixing end can be placed.

Das erfindungsgemäße Rahmenelement wird vorzugsweise als stranggepresste Aluminiumprofilleiste hergestellt. Das vergleichsweise geringe Gewicht von Aluminium führt dazu, dass dieses Material für Spannrahmen im Bereich der Kunstmalerei gut geeignet ist.The frame element according to the invention is preferably produced as an extruded aluminum profile strip. The comparatively low weight of aluminum means that this material is well suited for tenter frames in the field of art painting.

Das erfindungsgemäße Rahmenelement kann so ausgebildet werden, dass vier zusammengesetzte Rahmenelemente einen Spannrahmen bilden. Bei Bedarf können zwei Versteifungsstreben zur Stabilisierung des fertigen Spannrahmens verwendet werden. Das flächige Material kann dann mit Hilfe mehrerer Federn unmittelbar aufgespannt werden.The frame element according to the invention can be formed so that four composite frame elements form a clamping frame. If required, two stiffening braces can be used to stabilize the finished tenter frame. The sheet material can then be clamped directly by means of several springs.

Denkbar ist jedoch auch, das erfindungsgemäße Rahmenelement als an einem herkömmlichen Holzrahmen befestigbare Spanneinrichtung auszugestalten, so dass vier erfindungsgemäße Rahmenelemente auf der Rückseite eines ggf. bereits mit zwei Versteifungsstreben stabilisierten Holzrahmens befestigt werden können.It is also conceivable, however, to design the frame element according to the invention as a tensioning device which can be fastened to a conventional wooden frame, so that four frame elements according to the invention can be fastened on the rear side of a wooden frame which may already be stabilized with two stiffening struts.

Fig. 1 zeigt den Querschnitt eines ersten Ausführungsbeispiels des erfindungsgemäßen Rahmenelements 1. Es handelt sich um eine stranggepresste Aluminiumprofilleiste, die sich mit ihrer Längsrichtung in Blickrichtung der Fig. 1 erstreckt. Vier dieser Rahmenelemente 1 können wie in Fig. 1 der DE 103 12 637 A1 gezeigt zu einem fertigen quadratischen oder rechteckigen Spannrahmen zusammengesetzt werden, der hier nicht gezeigt ist. Fig. 1 shows the cross section of a first embodiment of the frame element according to the invention 1. It is an extruded aluminum profile strip, which with its longitudinal direction in the direction of the Fig. 1 extends. Four of these frame elements 1 can, as in Fig. 1 of the DE 103 12 637 A1 shown assembled into a finished square or rectangular tenter, which is not shown here.

Die in Fig. 1 der vorliegenden Anmeldung teilweise dargestellte Versteifungsstrebe 14 entspricht einer der beiden in Fig. 1 der DE 103 12 637 A1 gezeigten Versteifungsstreben 3 und 4. Die Versteifungsstrebe 14 ist vorzugsweise ebenso als stranggepresste Aluminiumprofilleiste hergestellt und greift in eine an dem Rahmenelement 1 vorgesehene Strebenaufnahme 15 ein. Das Rahmenelement 1 weist eine weitere Strebenaufnahme 16 auf, die bei dem konkret in Fig. 1 gezeigten Rahmenelement 1 nicht gebraucht wird. Die Strebenaufnahme 16 dient bei zwei anderen Rahmenelementen desselben Spannrahmens zur Aufnahme der hier nicht gezeigten Versteifungsstrebe, die senkrecht zu der in Fig. 1 gezeigten Versteifungsstrebe 14 verläuft.In the Fig. 1 The present invention partially illustrated stiffening strut 14 corresponds to one of the two in Fig. 1 of the DE 103 12 637 A1 shown stiffening struts 3 and 4. The stiffening strut 14 is preferably also prepared as an extruded aluminum profile strip and engages in a provided on the frame member 1 strut mount 15 a. The frame element 1 has a further strut receptacle 16 , which in the concrete in Fig. 1 shown frame element 1 is not needed. The strut receptacle 16 is used in two other frame members of the same clamping frame for receiving the reinforcing strut, not shown here, perpendicular to the in Fig. 1 shown stiffening strut 14 extends.

Das Rahmenelement 1 weist einen Spannhohlraum 2 auf, der in Fig. 1 durch eine Strichlinie 17 gekennzeichnet ist und bei dem gezeigten Ausführungsbeispiel im Wesentlichen eine Rechteckform aufweist. Der Spannhohlraum 2 wird von den Profilwänden 18, 19 und 20 sowie einem Teil der Fixiereinrichtung 10 begrenzt. Auf seiner in Fig. 1 linken Seite ist der Spannhohlraum 2 offen, so dass er von dieser Seite aus zugänglich ist.The frame element 1 has a clamping cavity 2 , which in Fig. 1 is characterized by a dashed line 17 and in the embodiment shown has a substantially rectangular shape. The clamping cavity 2 is bounded by the profile walls 18, 19 and 20 and a part of the fixing device 10 . On his in Fig. 1 left side of the clamping cavity 2 is open, so that it is accessible from this side.

In Verlängerung der Profilwand 18 nach rechts ist eine weitere Profilwand 21 vorhanden. Das linke Ende der Profilwand 18 ist mit einer Verdickung 22 und das rechte Ende der Profilwand 21 mit einer Verdickung 23 versehen. Wie in Fig. 1 zu erkennen, dienen die Verdickung 23, die Profilwand 21, die Profilwand 18 und die Verdickung 22 der Führung des flächigen Materials 5 in Form einer Leinwand, die durch eine gepunktete Linie dargestellt ist.In extension of the profile wall 18 to the right, a further profile wall 21 is present. The left end of the profile wall 18 is provided with a thickening 22 and the right end of the profile wall 21 with a thickening 23 . As in Fig. 1 recognize the thickening 23, the profile wall 21, the profile wall 18 and the thickening 22 of the guide of the sheet material 5 in the form of a canvas, which is represented by a dotted line.

In dem Spannhohlraum 2 befindet sich eine Vielzahl von Federn 4, wobei in der Querschnittsdarstellung gemäß Fig. 1 nur eine Feder 4 gezeigt ist. Die Feder 4 beaufschlagt die Leinwand 5 in dem Spannhohlraum 2 in einer Spannrichtung SR mit einer Spannkraft SK. Dabei drückt ein hakenförmig gebogenes Spannende 7 der Feder 4 in der Spannrichtung SR gegen die Leinwand 5. Die Feder 4 ist mit einem dem Spannende 7 gegenüberliegenden Fixierende 6 an der Fixiereinrichtung 10 fixiert.In the clamping cavity 2 is a plurality of springs 4, wherein in the cross-sectional view according to Fig. 1 only one spring 4 is shown. The spring 4 acts on the screen 5 in the clamping cavity 2 in a clamping direction SR with a clamping force SK. This presses a hook-shaped curved exciting 7 of the spring 4 in the tensioning direction SR against the screen 5. The spring 4 is fixed to the fixing device 10 by means of a fixing end 6 opposite the exciting end 7 .

Die Fixiereinrichtung 10 besteht bei dem gezeigten Ausführungsbeispiel aus einer im Querschnitt im Wesentlichen kreisförmigen Fixieraussparung 3. Zum Fixieren der Leinwand 5 in der Fixieraussparung 3 wird ein Abschnitt der Leinwand 5 zunächst durch eine Öffnung 9 in die Fixieraussparung 3 eingebracht. Dann wird das Fixierende 6 der Feder 4 durch die Öffnung 9 gedrückt. Anschließend kann das freie Ende 24 der Leinwand 5 in Fig. 1 nach links gezogen werden bis sich das Spannende 7 der Feder 4 entgegen der eingezeichneten Spannrichtung SR bewegt. In diesem Zustand ist die Feder 4 schließlich gespannt und drückt in Fig. 1 im Wesentlichen von links oben in Spannrichtung SR auf die Leinwand 5. Dabei liegt die Leinwand 5 nicht an der Profilwand 19 an, so dass die Leinwand 5 unter mechanischer Spannung steht.In the exemplary embodiment shown, the fixing device 10 comprises a fixing recess 3 , which is essentially circular in cross-section . For fixing the screen 5 in the fixing recess 3 , a section of the screen 5 is first introduced through an opening 9 into the fixing recess 3 . Then, the fixing end 6 of the spring 4 is pushed through the opening 9 . Subsequently, the free end 24 of the canvas 5 in Fig. 1 are pulled to the left until the exciting 7 of the spring 4 moves against the drawn clamping direction SR. In this state, the spring 4 is finally stretched and pushes in Fig. 1 essentially from the top left in the tensioning direction SR on the screen 5. In this case, the screen 5 does not rest against the profile wall 19 , so that the screen 5 is under mechanical tension.

In ihrem gespannten Zustand trachtet die Leinwand 5 danach, das Spannende 7 der Feder 4 entgegen der Spannrichtung SR zu bewegen. Diese Bewegung des Spannendes 7 hätte eine Drehbewegung der Feder 4 um das Fixierende 6 im Gegenuhrzeigersinn zur Folge. Eine solche Drehbewegung lässt die bei dem gezeigten Ausführungsbeispiel als Drehlager ausgebildete Fixieraussparung 3 nur in begrenztem Umfang zu.In its tensioned state, the screen 5 seeks to move the exciting 7 of the spring 4 against the clamping direction SR. This movement of the exciting end 7 would result in a rotational movement of the spring 4 about the fixing end 6 in the counterclockwise direction. Such a rotational movement can be in the embodiment shown as a pivot bearing formed Fixieraussparung 3 only to a limited extent.

Wie in Fig. 1 gezeigt ist das Fixierende 6 der Feder 4 in der Art eines Hakens etwa halbkreisförmig gebogen. Eine Anschlagfläche 8 ragt im Wesentlichen radial in die kreisförmige Fixieraussparung 3 hinein. Sobald das freie Ende des hakenförmigen Fixierendes 6 an der Anschlagfläche 8 anliegt, wird die Drehbewegung der Feder 4 im Gegenuhrzeigersinn unterbunden und die Feder 4 wird durch Biegen im Gegenuhrzeigersinn gespannt. Ihre Rückstellkraft wirkt dann in der Spannrichtung SR auf die Leinwand 5. Des Weiteren drückt in diesem Zustand das Fixierende 6 einen Abschnitt der in der Fixieraussparung 3 befindlichen Leinwand 5 gegen die kreisförmig gewölbte Innenwand der Fixieraussparung 3. Dadurch wird dieser Abschnitt der Leinwand 5 zwischen dem Fixierende 6 und der Innenwand der Fixieraussparung 3 ein- bzw. festgeklemmt. Eine zusätzliche Klemmung der Leinwand 5 erfolgt außerdem zwischen dem freien Ende des Fixierendes 6 und der Anschlagfläche 8. Die Leinwand 5 wird somit reibschlüssig aufgrund der Haftreibung zwischen der Leinwand 5 und dem Fixierende 6 einerseits sowie der Leinwand 5 und der Innenwand der Fixieraussparung 3 andererseits in der Fixieraussparung 3 gehalten.As in Fig. 1 shown, the fixing end 6 of the spring 4 is bent in the manner of a hook approximately semicircular. A stop surface 8 projects substantially radially into the circular fixing recess 3 . As soon as the free end of the hook-shaped fixing 6 rests against the stop surface 8 , the rotational movement of the spring 4 is prevented in the counterclockwise direction and the spring 4 is tensioned by bending in the counterclockwise direction. Their restoring force then acts on the screen 5 in the tensioning direction SR. Furthermore, in this state, the fixing end 6 presses a portion of the screen 5 located in the fixing recess 3 against the circularly curved inner wall of the fixing recess 3. As a result, this portion of the screen 5 between the fixing end 6 and the inner wall of the Fixieraussparung 3 on or clamped. An additional clamping of the screen 5 also takes place between the free end of the fixing 6 and the stop surface 8. The canvas 5 is thus frictionally due to the static friction between the canvas 5 and the fixing end 6 on the one hand and the canvas 5 and the inner wall of Fixieraussparung 3 on the other held the Fixieraussparung 3 .

Bei dem gezeigten Ausführungsbeispiel ist auf der in Fig. 1 rechten Seite der Öffnung 9 eine Führungsfläche 11 angeordnet. Auf dieser Führungsfläche 11 kann die Leinwand 5 abschnittsweise anliegen, wodurch sie aus der Fixieraussparung 3 herausgeführt wird. Bei dem gezeigten Ausführungsbeispiel verläuft ein größerer Teil der Führungsfläche 11 außerhalb der Fixieraussparung 3 und ein kleinerer Teil der Führungsfläche 11 innerhalb der Fixieraussparung 3. Genau auf der Rückseite des innerhalb der Fixieraussparung 3 verlaufenden Teils der Führungsfläche 11 befindet sich die Anschlagfläche 8. In the embodiment shown is on the in Fig. 1 right side of the opening 9, a guide surface 11 is arranged. On this guide surface 11 , the canvas 5 abut in sections, whereby it is led out of the Fixieraussparung 3 . In the embodiment shown, a larger part of the guide surface 11 extends outside of the Fixieraussparung 3 and a smaller part of the guide surface 11 within the Fixieraussparung 3. Exactly on the back of extending within the Fixieraussparung 3 part of the guide surface 11 is the stop surface. 8

Wie in Fig. 1 zu erkennen ist, befindet sich die separat von dem Rahmenelement 1 vorgesehene Feder 4 samt ihrem Spannende 7 und ihrem Fixierende 6 vollständig in dem Spannhohlraum 2. Kein Bestandteil der Feder 4 ragt in ihrem an dem Rahmenelement 1 montiertem Zustand nach links über die Strichlinie 17 hinaus aus dem Spannhohlraum 2 heraus. Die Gefahr, dass durch die Handhabung eines aus mehreren erfindungsgemäßen Rahmenelementen 1 zusammengesetzten Spannrahmens, auf den eine Leinwand 5 aufgespannt ist, eine oder mehrere der Federn 4 gelöst werden, ist erheblich reduziert. Aufwändiges und lästiges Wiedereinsetzen gelöster Federn wie im Stand der Technik erübrigt sich daher.As in Fig. 1 can be seen, is provided separately from the frame member 1 spring 4 together with its exciting 7 and its fixing end 6 completely in the clamping cavity 2. No component of the spring 4 protrudes in its mounted on the frame member 1 state to the left on the dotted line 17 addition out of the clamping cavity 2 out. The risk that one or more of the springs 4 are solved by the handling of a composite of several inventive frame members 1 clamping frame on which a canvas 5 is clamped, is considerably reduced. Elaborate and annoying re-insertion of dissolved springs as in the prior art is therefore unnecessary.

Fig. 2 zeigt dasselbe Ausführungsbeispiel des Rahmenelements 1 wie Fig. 1 . Allerdings kommt hier eine andersartig geformte Feder 4 zum Einsatz. Der größte Teil des Federquerschnitts gemäß Fig. 2 verläuft gewölbt. Während das Fixierende 7 der in Fig. 1 gezeigten Feder hakenförmig gekrümmt ist, endet das Spannenende 7 der Feder 4 gemäß Fig. 2 ohne hakenförmige Krümmung. Der Übergang des Federkörpers in das Fixierende 6 erfolgt in Fig. 2 mittels einer Übergangskante 25. Das Fixierende 6 ist auch in Fig. 2 in etwa mit einem halbkreisförmigen Querschnitt ausgebildet. Das Zusammenwirken der in Fig. 2 gezeigten Feder 4 mit dem erfindungsgemäßen Rahmenelement 1 erfolgt in derselben Weise wie sie voranstehend in Zusammenhang mit der Fig. 1 beschrieben wurde. Fig. 2 shows the same embodiment of the frame member 1 as Fig. 1 , However, a differently shaped spring 4 is used here. The largest part of the spring cross-section according to Fig. 2 runs arched. While the fixating 7 of in Fig. 1 the spring shown is curved hook-shaped, that ends Clamping end 7 of the spring 4 according to Fig. 2 without hook-shaped curvature. The transition of the spring body in the fixing end 6 takes place in Fig. 2 by means of a transitional edge 25. The fixing end 6 is also in Fig. 2 formed approximately with a semicircular cross-section. The interaction of in Fig. 2 shown spring 4 with the frame element 1 according to the invention is carried out in the same manner as described above in connection with the Fig. 1 has been described.

Fig. 3 zeigt ein zweites Ausführungsbeispiel eines Querschnitts des erfindungsgemäßen Rahmenelements 1. Es unterscheidet sich von dem Ausführungsbeispiel gemäß der Fig. 1 und 2 durch eine abweichende Gestaltung der Fixiereinrichtung 10. Die Fixiereinrichtung 10 weist bei diesem Ausführungsbeispiel eine Fixieraussparung 3 mit einem Querschnitt in Form eines ¼-Kreisringes auf. An gegenüberliegenden Begrenzungswandungen der Fixieraussparung 3 sind Widerhaken 12 angeordnet, welche in die Leinwand 5 eingreifen und dadurch eine formschlüssige Sicherung der Leinwand 5 in der Fixieraussparung 3 gegen Herausziehen ermöglichen. Fig. 3 shows a second embodiment of a cross section of the frame element according to the invention 1. It differs from the embodiment according to the Fig. 1 and 2 by a different design of the fixing device 10. The fixing device 10 has in this embodiment a Fixieraussparung 3 with a cross section in the form of a ¼-circular ring. At opposite boundary walls of the Fixieraussparung 3 barbs 12 are arranged, which engage in the canvas 5 and thereby allow a positive securing the screen 5 in the Fixieraussparung 3 against pulling out.

Das Fixierende 6 der Feder 4 gemäß Fig. 3 ist flacher gekrümmt als die in den Fig. 1 und 2 gezeigten Fixierenden 6 und folgt in seinem Krümmungsverlauf in etwa der Querschnittsform der Fixieraussparung 3. Wenn das freie Ende des Fixierendes 6 die eine Begrenzungswandung der Fixieraussparung 3 bildende Endfläche 26 erreicht, wirkt die Endfläche 26 wie die Anschlagfläche 8 in Fig. 1 als Anschlag zur Begrenzung der Drehbewegung der Feder 4. The fixing end 6 of the spring 4 according to Fig. 3 is curved more flat than the one in the Fig. 1 and 2 fixing shown in 6 and follows its curvature roughly to the cross-sectional shape of the locating recess 3. When the free end of the bracing 6, a boundary wall of the fixing recess 3 forming end surface 26 is reached, the end surface 26 acts as the stop surface 8 in Fig. 1 as a stop for limiting the rotational movement of the spring . 4

Das Spannende 7 der Feder 4 ist geringfügig gebogen und der Querschnitt des Federkörpers verläuft im Übrigen geradlinig. Wie in Fig. 3 zu erkennen ist, kann die Leinwand 5 dadurch flächig an der Feder 4 anliegen. Die grundsätzliche Funktionsweise des Ausführungsbeispiels gemäß Fig. 3 ist im Übrigen dieselbe wie sie in Zusammenhang mit Fig. 1 beschrieben wurde.The exciting 7 of the spring 4 is slightly bent and the cross section of the spring body is otherwise rectilinear. As in Fig. 3 can be seen, the canvas 5 can thereby lie flat against the spring 4 . The basic operation of the embodiment according to Fig. 3 is, moreover, the same as related to Fig. 1 has been described.

Fig. 4 zeigt ein drittes Ausführungsbeispiel eines Querschnitts des erfindungsgemäßen Rahmenelements 1. Es unterscheidet sich von den Ausführungsbeispielen gemäß der Fig. 1-3 durch eine abweichende Gestaltung der Fixiereinrichtung 10. Die Fixiereinrichtung 10 ist hier in Form einer Fixieraussparung 3 mit einem länglichen geradlinigen Querschnitt ausgebildet, der einen linken Hinterschneidungsbereich 27 und einen rechten Hinterschneidungsbereich 28 aufweist. Fig. 4 shows a third embodiment of a cross section of the frame element according to the invention 1. It differs from the embodiments according to the Fig. 1-3 by a different design of the fixing device 10. The fixing device 10 is formed here in the form of a Fixieraussparung 3 with an elongated rectilinear cross section having a left undercut region 27 and a right undercut region 28 .

Der Querschnitt des Fixierendes 6 der Feder 4 ist bei dem in Fig. 4 gezeigten Ausführungsbeispiel in der Art eines auf dem Kopf stehenden großen T ausgebildet. Das in die Fixieraussparung 3 eingeführte Fixierende 6 hintergreift mit seinem in Fig. 4 horizontal verlaufenden T-Steg die Hinterschneidungsbereiche 27 und 28. Im gespannten Zustand der Leinwand 5 stellt sich eine geringfügige Verkantung des T-Stegs in der Fixieraussparung 3 derart ein, dass der in Fig. 4 linke Bereich des T-Stegs an der unteren Begrenzungswand der Fixieraussparung 3 anliegt und der in Fig. 4 rechte Bereich des T-Stegs an der oberen Begrenzungswand des Hinterschneidungsbereichs 28 anliegt. Dadurch ergibt sich eine leicht im Gegenuhrzeigersinn geneigte Kippstellung der Feder 4. The cross section of the fixing end 6 of the spring 4 is in the in Fig. 4 embodiment shown formed in the manner of an inverted large T. The introduced into the Fixieraussparung 3 Fixierende 6 engages with his in Fig. 4 horizontally extending T-bar the undercut areas 27 and 28. In the tensioned state of the screen 5 is a slight tilting of the T-bridge in the Fixieraussparung 3 such that the in Fig. 4 left portion of the T-bar rests against the lower boundary wall of Fixieraussparung 3 and the in Fig. 4 right portion of the T-bar on the upper boundary wall of the undercut region 28 abuts. This results in a slightly counterclockwise tilted position of the spring . 4

Abweichend von den Ausführungsbeispielen gemäß der Fig. 1-3 ermöglicht die Geometrie der Fixieraussparung 3 gemäß Fig. 4 keine drehlagerartige Funktionalität. Ein Drehen der Feder 4 um ihr Fixierende 6 ist nur im Umfang der voranstehend erläuterten Verkantung des T-Stegs in der Fixieraussparung 3 möglich.Notwithstanding the embodiments according to the Fig. 1-3 allows the geometry of the Fixieraussparung 3 according to Fig. 4 no rotary bearing-like functionality. A rotation of the spring 4 about its fixing end 6 is possible only in the scope of the above-explained tilting of the T-bar in the fixing recess 3 .

Im Vergleich zu der in Fig. 2 gezeigten Feder ist der in Fig. 4 gezeigte Federkörper zunächst flacher gekrümmt und läuft schließlich an seinem Spannende 7 mit einer stärkeren Krümmung aus. Mit Ausnahme der voranstehend genannten Unterschiede ist die grundsätzliche Funktionsweise des Ausführungsbeispiels gemäß Fig. 4 dieselbe wie sie in Zusammenhang mit Fig. 1 beschrieben wurde.Compared to the in Fig. 2 shown spring is the in Fig. 4 shown spring body initially curved flat and finally runs at its exciting 7 with a greater curvature. With the exception of the differences mentioned above, the basic mode of operation of the exemplary embodiment is according to FIG Fig. 4 the same as her in connection with Fig. 1 has been described.

Fig. 5 zeigt ein viertes Ausführungsbeispiel eines Querschnitts des erfindungsgemäßen Rahmenelements 1. Es unterscheidet sich von den Ausführungsbeispielen gemäß der Fig. 1-4 durch eine abweichende Gestaltung der Fixiereinrichtung 10. Anstelle einer Fixieraussparung wie in den Ausführungsbeispielen gemäß der Fig. 1-4 ist hier ein Fixiervorsprung 13 vorgesehen, der unter einem Neigungswinkel aus der Profilwand 20 hervorsteht. Der Fixiervorsprung 13 ragt als Leiste aus der Profilwand 20 heraus, die an ihrem in Fig. 5 oberen, freien Ende eine im Querschnitt etwa kreisförmige Verdickung 29 aufweist, die einer nicht zu scharfkantigen Führung der Leinwand 5 um das freie Ende des leistenförmigen Fixiervorsprungs 13 dient. Fig. 5 shows a fourth embodiment of a cross section of the frame element according to the invention 1. It differs from the embodiments according to the Fig. 1-4 by a different design of the fixing device 10. Instead of a Fixieraussparung as in the embodiments according to the Fig. 1-4 Here, a fixing projection 13 is provided which protrudes from the profile wall 20 at an angle of inclination. The Fixiervorsprung 13 protrudes as a bar out of the profile wall 20 , at its in Fig. 5 upper, free end has a cross-sectionally approximately circular thickening 29 , which serves a not too sharp-edged guide the canvas 5 to the free end of the strip-shaped fixing projection 13 .

Das Fixierende 6 der Feder 4 ist in Fig. 5 in der Art einer Negativform des Fixiervorsprungs 13 ausgebildet. Das Fixierende 6 weist einen Federhohlraum 30 auf, mit welchem das Fixierende 6 auf den Fixiervorsprung 13 gesteckt wird.
