Abstract

The supporting and suspending frame, detachably assembled from a plurality of supporting frame elements, serves to suspend flat reproductions, in particular photographic reproductions, of paper, film or fabric smoothly in the frame by means of tensioning springs. Every supporting frame element has an at least partly circularly curved narrow side and a contiguous flat wide side at right angles thereto. The inside face of the wide side is provided with a supporting member that extends in the longitudinal direction of the wide side and is open in the transverse direction of the wide side. The tensioning springs, which are fastened to the edges of the reproduction by means of eyes, can be suspended directly in and displaced along the supporting member. As a result, it is possible to wrap the reproduction over the wide side and the narrow side toward the back side of the supporting frame element and there fasten it smoothly by means of the suspended tensioning springs, so that the reproduction is clamped or displayed in a "borderless" manner.

Description

Die Erfindung betrifft eine Aufspannvorrichtung für flächen­hafte Reproduktionen, insbesondere photographische Reproduk­tionen, gemäss dem Oberbegriff des Patentanspruchs 1.The invention relates to a clamping device for two-dimensional reproductions, in particular photographic reproductions, according to the preamble of patent claim 1.

Es ist seit längerem bekannt, grossflächige photographische Bilder auf Papier oder Film in einem rechteckigen äusseren Rahmen mittels Spannfedern aufzuspannen, die einerseits längs des Randes des Bildes und andererseits längs des be­treffenden Rahmenstücks befestigt sind. Aus der Europäischen Patentameldung Nr. 84 304 393.6 (Publikation Nr. 0 132 953) ist zudem eine Aufspannvorrichtung dieser Art bekannt gewor­den, bei welcher mehrere lösbar durch Klemmverbindungsele­mente miteinander zu einem Rahmen zusammengesetzte Rahmen­profilstücke innere Schienen aufweisen, in welchen Gleiter angeordnet sind, in welchen die an der Reproduktion be­festigte Spannfedern eingehängt werden können. Nachteilig bei dieser bekannten Aufspannvorrichtung ist, dass ihre Herstellung verhältnismässig aufwendig ist, dass beim Zusammenbau des Rahmens immer darauf geachtet werden muss, ob ausreichend viele Gleiter eingelegt sind, und vor allem, dass es nicht möglich ist, eine optisch rahmenlose Auf­spannvorrichtung zu erzielen, das heisst, eine Aufspann­vorrichtung, bei der sich die Reproduktion allseitig bis an die äussersten Ränder erstreckt und nirgends durch ein sichtbares Rahmenteil abgedeckt ist.It has long been known to clamp large-area photographic images on paper or film in a rectangular outer frame by means of tension springs which are fastened on the one hand along the edge of the image and on the other hand along the relevant frame piece. From the European Patent Application No. 84 304 393.6 (publication No. 0 132 953), a clamping device of this type has also become known, in which several frame profile pieces detachably joined together to form a frame by means of clamping connecting elements have inner rails in which sliders are arranged, in which the tension springs attached to the reproduction can be attached. A disadvantage of this known clamping device is that it is relatively expensive to manufacture, that when the frame is being assembled, care must always be taken to ensure that a sufficient number of sliders are inserted, and above all, that it is not possible to achieve an optically frameless clamping device, that is, a clamping device in which the reproduction extends on all sides to the outermost edges and is nowhere covered by a visible frame part.

Aufgabe der vorliegenden Erfindung ist, eine Aufspannvor­richtung der eingangs genannten Art zu schaffen, die nur einfach ausgebildete Rahmenprofilstücke mit Mitteln zum direkten, jedoch verschiebbaren Einhängen von Spannfedern benötigt und die das Aufspannen von Reproduktionen ohne Abdeckung durch sichtbare Rahmenteile ermöglicht.The object of the present invention is to provide a clamping device of the type mentioned at the outset which only requires simple frame profile pieces with means for directly but displaceably suspending tension springs and which enables reproductions to be clamped without cover by visible frame parts.

Erfindungsgemäss weist die Aufspannvorrichtung die im kenn­zeichnenden Teil des Patentanspruchs 1 angeführten Merkmale auf.According to the invention, the clamping device has the features stated in the characterizing part of patent claim 1.

Embodiments of the invention are explained in more detail below with reference to the drawing. Show it :
  • Figure 1 shows the cross section of a frame profile piece according to the invention with a reproduction spanned according to an "edge-free";
  • FIG. 2 shows the cross section of the frame profile piece of FIG. 1 with a stretched reproduction covered at the edge by the frame;

Fig. 1 zeigt den Querschnitt eines beispielsweisen Rahmen­profilstücks gemäss der Erfindung. Generell gesehen hat das Rahmenprofilstück eine Schmalseite 1 und eine Breitseite 2. Die Schmalseite 1 ist im wesentlichen halbkreisbogenförmig mit einem kurzen, nach innen abgebogenen Endbereich 3. Die Breitseite 2 ist eben und weist einen unteren Endbereich 4 auf, der ebenfalls kreisbogenförmig ausgebildet ist, jedoch mit einem kleineren Radius als derjenige der halbkreisbogen­förmigen Schmalseite 1. Im Inneren des Rahmenprofilstücks sind verschiedene vorspringende Profilteile vorgesehen, die unterschiedlichen Zwecken dienen. Ein solcher an erster Stelle zu erwähnendes Profilteil ist ein in dem von der Schmalseite 1 abgewandten Endbereich der Breitseite 2 be­findlicher schienenartiger Vorsprung 5, der zum kreisbogen­ förmigen Endbereich 4 hin offen ist und der sich über die ganze Länge des Rahmenprofilstücks erstreckt. Wie darge­stellt, dient der schienenartige Vorsprung 5 zum Ein­hängen mehrerer Spannfedern 6 (nur eine in Fig. 1 sicht­bar), die mit ihren entgegengesetzten Enden in längs des betreffenden Randes der flächenhaften Reproduktion 7 ange­brachten Oesen 8 eingehängt sind. Die Reproduktion 7 ist, wie ersichtlich, um die halbkreisbogenförmige Schmalseite 1 über die anschliessende Breitseite 2 geführt und erstreckt sich dann bis zu einem gegenüberliegenden Rahmenprofilstück des Aufspannrahmens, wo sie in gleicher Weise über dessen Breitseite und Schmalseite zur Innenseite des Rahmenprofil­stücks geführt ist und dort mittels Spannfedern am Rahmen­profilstück eingehängt ist. Das gleiche gilt auch für die beiden anderen Seiten der Reproduktion bzw. des Aufspann­rahmens.Fig. 1 shows the cross section of an exemplary frame profile piece according to the invention. Generally speaking, the frame profile piece has a narrow side 1 and a broad side 2. The narrow side 1 is essentially semicircular in shape with a short end region 3 which is bent inwards. The broad side 2 is flat and has a lower end region 4, which is likewise designed in the shape of a circular arc, however with a smaller radius than that of the semicircular narrow side 1. In the interior of the frame profile piece, various projecting profile parts are provided, which serve different purposes. Such a profile part to be mentioned in the first place is a rail-like projection 5 located in the end region of the broad side 2 facing away from the narrow side 1, which protrudes toward the arc shaped end portion 4 is open and which extends over the entire length of the frame profile piece. As shown, the rail-like projection 5 serves to hang in a plurality of tension springs 6 (only one visible in FIG. 1), which are suspended with their opposite ends in eyelets 8 attached along the relevant edge of the areal reproduction 7. The reproduction 7, as can be seen, is guided around the semicircular narrow side 1 over the adjoining broad side 2 and then extends to an opposite frame profile piece of the clamping frame, where it is guided in the same way over the broad side and narrow side to the inside of the frame profile piece and there by means of Tension springs is attached to the frame profile piece. The same applies to the other two sides of the reproduction or the mounting frame.

Es ist ersichtlich, dass bei dieser Aufspannvorrichtung keine Randpartien der Reproduktion durch irgendwelche Rahmenteile abgedeckt sind, und dass sich ein glattes Spannen der Reproduktion in einfacher Weise durch passen­des Verschieben der Spannfedern 6 in den schienenartigen Vorsprüngen 5 erzielen lässt. Zudem ermöglicht diese "randlose" Ausbildungsform ein praktisch nahtloses Aneinan­derreihen mehrerer gleicher Aufspannvorrichtungen zu einem sehr grossflächigen Grossbild.It can be seen that in this clamping device no marginal parts of the reproduction are covered by any frame parts, and that a smooth clamping of the reproduction can be achieved in a simple manner by appropriately moving the tension springs 6 in the rail-like projections 5. In addition, this "borderless" form of training enables a practically seamless stringing together of several identical clamping devices to form a very large-scale image.

In Fig. 2 ist der Querschnitt eines gleichen Rahmenprofil­stücks dargestellt, bei welchem ein weiteres vorspringen­des Profilteil benutzt wird. Es ist dies ein nahe der Schmalseite 1 an der Innenfläche der Breitseite 2 vorge­sehener schienenartiger Vorsprung 9, der zur Schmalseite 1 hin offen ist und der sich über die ganze Länge des Rahmen­profilstücks erstreckt. Wie dargestellt, dient der schie­nenartige Vorsprung 9 zum Einhängen mehrerer Spannfedern 6 (nur eine in Fig. 2 sichtbar), die mit ihren entgegenge­setzten Enden wiederum in längs des betreffenden Randes der flächenhaften Reproduktion 7 angebrachten Oesen 8 einge­hängt sind. Bei dieser mit den gleichen Rahmenprofilstücken erzielbaren Aufspannart sind jedoch die Randpartien der Reproduktion 7 durch die Breitseite 2 und die Schmalseite 1 in an sich bekannter Weise abgedeckt. Die gebogenen Formen der Schmalseite 1 und des Endbereichs 4 der Breit­seite 2 schaffen jedoch ein wesentlich gefälligeres und leichteres Aussehen des sichtbaren Rahmens.In Fig. 2 the cross section of a same frame profile piece is shown, in which a further projecting profile part is used. This is a rail-like projection 9 provided near the narrow side 1 on the inner surface of the broad side 2, which is open towards the narrow side 1 and extends over the entire length of the frame profile piece. As shown, the rail-like projection 9 serves to hang in a plurality of tension springs 6 (only one visible in FIG. 2), which in turn are hooked with their opposite ends into eyelets 8 attached along the relevant edge of the areal reproduction 7. In this type of clamping which can be achieved with the same frame profile pieces, however, the edge parts of the reproduction 7 are covered by the broad side 2 and the narrow side 1 in a manner known per se. However, the curved shapes of the narrow side 1 and the end region 4 of the broad side 2 create a much more pleasing and light appearance of the visible frame.

Ein vollständiger Aufspannrahmen wird aus mehreren Rahmen­profilstücken gemäss Fig. 1 und 2 zusammengesetzt, wobei fugenlose Eckverbindungen durch entsprechende Gehrungs­schnitte erzielt werden. Wird die Reproduktion 7 gemäss Fig. 1 aufgespannt, das heisst über die Breitseiten 2 und die gebogenen Schmalseiten 1 gezogen, so ist selbstver­ständlich ein Eckzuschnitt der Reproduktion 7 erforderlich, um ein störendes Ueberlappen zu vermeiden. In Fig. 3 ist ein entsprechender Eckzuschnitt 10 einer mit den Randösen 8 versehenen Reproduktion 7 dargestellt. Bei einem derart ausgebildeten Zuschnitt stossen die Ränder 11 des Zu­schnitts 10 direkt, das heisst ohne Ueberlappung und ohne Trennfugenbildung, aneinander.A complete mounting frame is composed of several frame profile pieces according to FIGS. 1 and 2, with seamless corner connections being achieved by corresponding miter cuts. If the reproduction 7 is stretched according to FIG. 1, that is to say pulled over the broad sides 2 and the curved narrow sides 1, then a corner cut of the reproduction 7 is of course necessary. to avoid annoying overlap. FIG. 3 shows a corresponding corner cut 10 of a reproduction 7 provided with the eyelets 8. In the case of a blank of this type, the edges 11 of the blank 10 abut one another directly, that is to say without overlap and without formation of parting lines.

Zum erwähnten Zusammensetzen mehrerer Rahmenprofilstücke gemäss Fig. 1 und 2 kommen mit Vorteil an sich bekannte Klemmverbindungselemente zur Anwendung. In Fig. 4 ist die rückseitige Ansicht eines vollständigen Aufspann­rahmens 12 mit solchen Klemmverbindungselementen darge­stellt.For the aforementioned assembly of a plurality of frame profile pieces according to FIGS. 1 and 2, known clamping connection elements are advantageously used. FIG. 4 shows the rear view of a complete clamping frame 12 with such clamping connection elements.

Gemäss Fig. 4 sind vordere Längs-Klemmverbindungselemente 13 und seitliche Längs-Klemmverbindungselemente vorge­sehen, die Schrauben enthalten und deshalb ohne weiteres lösbar sind. Entsprechende vordere Eck-Klemmverbindungs­elemente 15 und seitliche Eck-Klemmverbindungselemente 16 sind in den inneren Ecken des Aufspannrahmens 12 vorge­sehen. Falls die Längenabmessung des Aufspannrahmens 12 beträchtlich ist, empfiehlt es sich zudem, zur Vermeidung eines Durchhangs eingelegte Abstützstäbe 17 vorzusehen.4, front longitudinal clamping connecting elements 13 and lateral longitudinal clamping connecting elements are provided, which contain screws and are therefore easily detachable. Corresponding front corner clamp connection elements 15 and lateral corner clamp connection elements 16 are provided in the inner corners of the mounting frame 12. If the length dimension of the mounting frame 12 is considerable, it is also advisable to provide support rods 17 to prevent sagging.

Die Ausbildung der Rahmenprofilstücke zur Aufnahme der Klemmverbindungselemente 13 bis 16 und der Abstützstäbe ergibt sich aus Fig. 5, in welcher der Querschnitt eines Rahmenprofilstücks gemäss Fig. 1 und nochmals dargestellt ist. Zur Aufnahme der vorderen Längs-Klemmverbindungsele­mente 13 sowie der Schenkel der vorderen Eck-Klemmver­bindungslemente 15 ist die Innenfläche der Breitseite 2 mit zwei schienenartigen Vorsprüngen 18 und 19 versehen, von welchen der eine Vorsprung 18 einstückig mit dem zum Einhängen der Spannfedern vorgesehenen schienenartigen Vor­sprung 5, und der andere Vorsprung 19 einstückig mit dem ebenfalls zum Einhängen der Spannfedern vorgesehenen schienenartigen Vorsprung 9 ausgebildet ist. Zur Aufnahme der seitlichen Längs-Klemmverbindungselemente 14 und der Schenkel der seitlichen Eck-Klemmverbindungselemente 16 sind im Innern der halbkreisbogenförmigen Schmalseite 1 zwei weitere schienenartige Vorsprünge 20 vorgesehen. Um die Abstützstäbe 17 an die inneren Wände der halbkreisbogen­förmigen Schmalseiten anlegen zu können, sind diese mit einer in Fig. 5 dargestellte, als ebene Auflagefläche ausgebildeten Verdickung 21 versehen.The formation of the frame profile pieces for receiving the clamping connecting elements 13 to 16 and the support rods results from Fig. 5, in which the cross section of a frame profile piece according to Fig. 1 and is shown again. To accommodate the front longitudinal clamping connection elements 13 and the legs of the front corner clamping connection elements 15, the inner surface of the broad side 2 is provided with two rail-like projections 18 and 19, of which one projection 18 is made in one piece with the rail-like projection 5 provided for hanging the tension springs, and the other projection 19 is formed in one piece with the rail-like projection 9, which is also provided for hooking in the tension springs. Two additional rail-like projections 20 are provided in the interior of the semicircular narrow side 1 to accommodate the lateral longitudinal clamping connecting elements 14 and the legs of the lateral corner clamping connecting elements 16. In order to be able to place the support rods 17 against the inner walls of the semicircular narrow sides, these are provided with a thickening 21 shown in FIG. 5 and designed as a flat bearing surface.

Bei dem in Fig. 5 dargestellten Klemmverbindungselement 13 ist als Betätigungsorgan in bekannter Weise eine Flügelmutter 22 vorgesehen. Aus Gründen knapper Raumverhältnisse wird beim Klemmverbindungselement 14 als Betätigungsorgan mit Vorteil eine Inbus-Schraube 23 verwendet.5, a wing nut 22 is provided as an actuator in a known manner. For reasons of limited space, an Allen screw 23 is advantageously used as the actuating member in the clamping connection element 14.

Es sind vorgängig Ausführungsformen von Rahmenprofilstücken beschrieben worden, bei welchen die Schmalseite des Profil­stücks halbkreisbogenförmig ist. Es ist aber auch möglich, diese Schmalseite so auszubilden, dass sie nur teilweise einer kreisbogenförmigen Verlauf hat, nämlich vorzugsweise in den beiden Kantenbereichen der Schmalseite. Auch dann ist es noch möglich, die flächenhafte Reproduktion von den Breitseiten her über die Schmalseiten zu den Rückseiten der Rahmenprofilstücke zu ziehen und dort mittels der in den Rahmenprofilstücken einhängbaren und verschiebbaren Spann­federn glatt zu spannen. Eine solche Ausführungsform mit nur teilweise kreisbogenförmigen Schmalseiten kann wegen des kleineren Krümmungsradius an den Kanten besonders dann von Vorteil sein, wenn, wie bereits erwähnt, mehrere Aufspann­vorrichtungen der vorliegenden Art zur Herstellung eines Grossbildes aneinandergefügt werden.Embodiments of frame profile pieces have previously been described in which the narrow side of the profile piece is semicircular. However, it is also possible to design this narrow side in such a way that it only partially has an arc-shaped course, namely preferably in the two edge regions of the narrow side. Even then, it is still possible to pull the areal reproduction from the broad sides over the narrow sides to the rear sides of the frame profile pieces and to tension them there smoothly by means of the tension springs which can be suspended and displaced in the frame profile pieces. Such an embodiment with only partially arcuate narrow sides can be particularly advantageous because of the smaller radius of curvature at the edges if, as already mentioned, several clamping devices of the present type are joined together to produce a large image.

Die vorliegende Aufspannvorrichtung bzw. ihre Rahmenprofil­stücke lassen sich verhältnismässig einfach und kostengünstig aus einem Leichtmetall herstellen, wobei eine hohe Steifig­keit erzielt wird. Das Aufhängen und Spannen einer flächen­haften Reproduktion aus Papier, einem Kunststoffmaterial oder einem textilen Material kann problemlos erfolgen. Die durch die Erfindung ermöglichte "randlose" Aufspannung einer Reproduktion ist von ganz besonderem praktischem und ästhe­tischem Interesse.The present clamping device or its frame profile pieces can be produced relatively easily and inexpensively from a light metal, with high rigidity being achieved. A flat reproduction made of paper, a plastic material or a textile material can be hung and tensioned without any problems. The "borderless" clamping of a reproduction made possible by the invention is of very special practical and aesthetic interest.
