Abstract

In the manufacture of frames, particularly wooden frames, the glued faces have to be pressed together along the bevelled cuts. For this purpose a clamping frame is suggested which comprises a closed rectangular clamping frame consisting of a first frame portion (10) consisting of two limbs (10a, 10b) at right-angles to each other and a second frame portion (16) consisting of two limbs (16a, 16b) at right-angles to each other. The second frame portion (16) is displaceable relatively to the first frame portion (10) and the limbs (16a, 16b) of the second frame portion (16) project outwardly beyond the limbs (10a, 10b) of the first frame portion (10). On the outside of the limbs (10a, 10b) of the first frame portion and parallel thereto there are pull rods (18) which intersect at the corner of the first frame portion (10) and engage the projecting limb sections of the second frame portion (16). Clamps (22) can be applied to the sections of the limbs of the second frame portion (16) that project beyond the limbs of the first frame portion (10) as well as to the pull rods (18), which clamps are supported on the outside of the limbs of the first frame portion (10) and with which the second frame portion (16) can be tightened to the first frame portion (10). By means of such a clamping frame, frames of different size can be clamped simply and conveniently.

Description

Die Erfindung betrifft einen Einspannrahmen für die Herstellung rechteckiger Rahmen, insbesondere Bilderrahmen, mit einem ersten aus zwei rechtwinkelig zueinander angeordneten und miteinander fest verbundenen Schenkeln bestehenden Rahmenteil und zwei weiteren, rechtwinkelig zueinander angeordneten und gegenüber dem ersten Rahmenteil verschieblich geführten Rahmenschenkein zur Bildung eines geschlossenen rechteckigen Spannrahmens, wobei die zwei weiteren Rahmenschenkel über die Schenkel des ersten Rahmenteils nach aussen vorstehen und ferner parallel zu den Schenkeln des ersten Rahmenteils auf deren Aussenseite verlaufende Zugstangen vorgesehen sind, die an den vorstehenden Abschnitten der zwei weiteren Rahmenschenkel angreifen.The invention relates to a clamping frame for the production of rectangular frames, in particular picture frames, with a first frame part consisting of two legs arranged at right angles and firmly connected to one another and two further frame legs arranged at right angles to one another and displaceably guided relative to the first frame part to form a closed rectangular tension frame , wherein the two further frame legs protrude outward beyond the legs of the first frame part and furthermore, parallel to the legs of the first frame part, are provided on the outside of the tie rods which engage the projecting sections of the two further frame legs.

Ein Einspannrahmen dieser Art ist beispielsweise aus der DK-PS 36 881 bekannt. Bei diesem Stand der Technik wird von einem ersten, aus zwei rechtwinkelig zueinander angeordneten Schenkeln bestehenden Rahmenteil und zwei weiteren, lose miteinander in Verbindung stehenden und gegenüber dem ersten Rahmenteil verschieblichen, ein zweites Rahmenteil bildenden Rahmenschenkeln zur Bildung eines geschlossenen Spannrahmens Gebrauch gemacht, wobei die zwei weiteren, lose gelagerten Rahmenschenkel jeweils durch eine Zugstange in Form einer Schraubenspindel getrennt voneinander gegen das erste Rahmenteil festgezogen werden können.A clamping frame of this type is known for example from DK-PS 36 881. In this prior art, use is made of a first frame part consisting of two legs arranged at right angles to one another and two further frame legs which are loosely connected to one another and displaceable relative to the first frame part and form a second frame part, to form a closed stenter frame, the two further, loosely supported frame legs can be tightened separately from each other against the first frame part by means of a pull rod in the form of a screw spindle.

Dabei sind die Schenkel des zweiten Rahmenteils in Längsschlitzen des ersten Rahmenteils geführt und sind die Schraubenspindeln an der Aussenseite der Schenkel des ersten Rahmenteils in mit dem ersten Rahmenteil starr verbundenen Führungsstücken gelagert.The legs of the second frame part are guided in longitudinal slots of the first frame part and the screw spindles are mounted on the outside of the legs of the first frame part in guide pieces rigidly connected to the first frame part.

In einer verbesserten Ausführungsform des Standes der Technik sind zwei weitere Schraubspindeln vorgesehen, die parallel zu den Schenkeln des zweiten Rahmenteils auf deren Aussenseite verlaufen, um jeweils die vorstehenden Enden der losen Schenkel des zweiten Rahmenteils gegenüber den vorstehenden Enden der festen Schenkel des ersten Rahmenteils festziehen zu können. Ein relativ aufwendiger Kettentrieb sorgt dafür, dass die zusätzlichen Schraubspindeln zusammen mit den ersten Schraubspindeln gedreht werden, so dass ein Verziehen des Spannrahmens vermieden wird.In an improved embodiment of the prior art, two further screw spindles are provided which run parallel to the legs of the second frame part on the outside thereof, in order to tighten the projecting ends of the loose legs of the second frame part relative to the projecting ends of the fixed legs of the first frame part can. A relatively complex chain drive ensures that the additional screw spindles are rotated together with the first screw spindles, so that warping of the clamping frame is avoided.

Dieser bekannte Spannrahmen erlaubt zwar schon in einfacher und bequemer Weise ein Einspannen von Rahmen unterschiedlicher Grösse, jedoch lässt bei der vereinfachten Ausführungsform die Stabilität des Einspannrahmens besonders an der durch die losen Schenkel des zweiten Rahmenteils gebildeten Ecke zu wünschen übrig. In der verbesserten Ausführungsform, bei der eine wesentlich gröseere Stabilität des Einspannrahmens beim Festziehen gegeben ist, ist der technische Aufwand relativ gross. Ferner ist das Einstellen auf unterschiedliche Bilderrahmengrössen relativ umständlich und zeitraubend, da dazu jedesmal die Schraubenspindeln mit der entsprechenden Anzahl von Umdrehungen betätigt werden müssen.Although this known clamping frame allows frames of different sizes to be clamped in a simple and convenient manner, in the simplified embodiment the stability of the clamping frame leaves a lot to be desired, particularly at the corner formed by the loose legs of the second frame part. In the improved embodiment, in which there is a much greater stability of the clamping frame when tightening, the technical effort is relatively great. Furthermore, the adjustment to different picture frame sizes is relatively cumbersome and time-consuming, since each time the screw spindles have to be actuated with the corresponding number of revolutions.

Aus der DE-PS 940 676 ist eine Vorrichtung zum Zusammenpressen von Holzrahmen bekannt, die eine Grundplatte aufweist, auf der ein aus zwei rechtwinkelig zueinander verlaufenden Rahmenschenkeln bestehendes erstes Rahmenteil befestigt ist. An den den festen Rahmenschenkeln des Einspannrahmens gegenüberliegenden Seiten ist jeweils mindestens eine Exzenterpresse vorgesehen, die auf die entsprechenden Seiten des einzuspannenden Rahmens unmittelbar einwirken. Diese Vorrichtung hat den Nachteil, dass sie sich nicht .zum Einspannen von Rahmen unterschiedlicher Grösse verwenden lässt, da dazu jedesmal die Position der Exzenterpressen geändert werden müsste.From DE-PS 940 676 a device for compressing wooden frames is known which has a base plate on which a first frame part consisting of two frame legs running at right angles to one another is fastened. At least one eccentric press is provided on each of the sides opposite the fixed frame legs of the clamping frame and acts directly on the corresponding sides of the frame to be clamped. This device has the disadvantage that it cannot be used for clamping frames of different sizes, since the position of the eccentric presses would have to be changed each time.

Aus der US-PS 27 53 902 ist ein Einspannrahmen bekannt, der im wesentlichen aus vier den Ecken des Einspannrahmens zugeordneten rechtwinkeligen Winkelstücken sowie aus vier Gewindestangen besteht, die jeweils in einem Schenkel eines Winkelstückes verankert und sich durch eine Bohrung im anderen Schenkel des anderen Winkelstückes lose hindurcherstrecken, wobei mit Hilfe einer Mutter das andere Winkelstück jeweils gegen das eine Winkelstück festgezogen werden kann.From US-PS 27 53 902 a clamping frame is known, which consists essentially of four assigned to the corners of the clamping frame right-angled elbows and four threaded rods, each anchored in one leg of an elbow and through a hole in the other leg of the other elbow stretch loosely, with the help of a nut the other elbow can be tightened against the one elbow.

Dieser Einspannrahmen erlaubt wiederum das Einspannen von Bilderrahmen unterschiedlicher Grösse, ist aber mit dem Nachteil behaftet, dass er beim Festspannen leicht verzogen werden kann, da die Winkelstücke erst beim Festspannen, das abwechselnd an allen vier Ecken des Rahmens zu erfolgen hat, in ihrer räumlichen Ausrichtung zueinander fixiert werden.This clamping frame in turn allows the clamping of picture frames of different sizes, but has the disadvantage that it can be easily warped when tightening, since the angular pieces only have to be spatially aligned when tightening, which has to take place alternately at all four corners of the frame fixed to each other.

Der Erfindung liegt nun die Aufgabe zugrunde, einen Einspannrahmen der eingangs genannten Art so auszubilden, dass bei geringem technischen Aufwand der Einspannrahmen verziehungsfrei festgespannt und ohne grössere Umstände jederzeit auf unterschiedliche Bilderrahmengrössen eingestellt werden kann.The invention is based on the object of designing a clamping frame of the type mentioned at the outset in such a way that the clamping frame can be clamped without warping with little technical effort and can be adjusted to different picture frame sizes at any time without major circumstances.

Diese Aufgabe wird erfindungsgemäss dadurch gelöst, dass die zwei weiteren Rahmenschenkel zur Bildung eines zweiten Rahmenteils fest miteinander verbunden sind, dass sich die Zugstangen an der Ecke des ersten Rahmenteils kreuzen und dass an den über die Schenkel des ersten Rahmenteils vorstehenden Abschnitten der Schenkel des zweiten Rahmenteils sowie der Zugstangen anbringbare und sich an der Aussenseite der Schenkel des ersten Rahmenteils abstützende Spannzwingen zum Festspannen des zweiten Rahmenteils am ersten Rahmenteil vorgesehen sind.This object is achieved according to the invention in that the two further frame legs are firmly connected to one another to form a second frame part, in that the tie rods intersect at the corner of the first frame part and in that on the portions of the legs of the second frame part protruding beyond the legs of the first frame part and the tie rods that can be attached and are supported on the outside of the legs of the first frame part are provided for clamping the second frame part on the first frame part.

Der Kern der Erfindung wird also im wesentlichen darin gesehen, dass der Einspannrahmen aus zwei gegeneinander verschieblichen festen bzw. starren Rahmenteilen zusammengesetzt ist, die mit Hilfe von Spannzwingen gegeneinander festlegbar sind. Auf diese Weise lässt sich der rechte Winkel an den Ecken des Einspannrahmens, insbesondere an den diagonal gegenüberliegenden Ecken, die durch die beiden festen Rahmenteile gebildet werden, beim Festspannen exakt aufrechterhalten, so dass sich in Verbindung mit der Verwendung von Spannzwingen - die überdies ein rasches Verstellen der Rahmengrösse gestatten - ein verziehungsfreies Festspannen des Einspannrahmens ergibt.The essence of the invention is therefore essentially seen in the fact that the clamping frame is composed of two fixed or rigid frame parts which are displaceable relative to one another, which can be fixed against each other with the help of clamps. In this way, the right angle at the corners of the clamping frame, in particular at the diagonally opposite corners, which are formed by the two fixed frame parts, can be exactly maintained when tightening, so that in connection with the use of clamping clamps - which moreover is quick Allow adjustment of the frame size - a distortion-free clamping of the clamping frame results.

Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben. Die Erfindung wird nun an einem Ausführungsbeispiel und anhand der einzigen beiliegenden, die Erfindung veranschaulichenden Figur erläutert.Further advantageous embodiments of the invention are specified in the subclaims. The invention will now be explained using an exemplary embodiment and with the aid of the single enclosed figure which illustrates the invention.

Wie aus der Figur hervorgeht, ist ein aus zwei rechtwinkelig zueinander angeordneten Schenkeln 10a, 10b bestehendes starres Rahmenteil 10 auf einer Grundplatte 12 derart befestigt, dass die im Profil L-förmig ausgebildeten Schenkel 10a und 10b die Grundplatte 12 untergreifen. Die Schenkel 10a und 10b des Rahmenteils 10 weisen jeweils einen Längsschlitz 14 auf, die von den zueinander rechtwinkelig verlaufenden Schenkeln 16a, 16b eines zweiten starren Rahmenteils 16 durchsetzt sind. Der zweite Rahmenteil 16 bildet dabei mit dem ersten Rahmenteil 10 einen rechteckigen Spannrahmen, dessen Grösse durch Verschieben des zweiten Rahmenteils 16 gegenüber dem ersten Rahmenteil 10 geändert werden kann.As can be seen from the figure, a rigid frame part 10 consisting of two legs 10a, 10b arranged at right angles to one another is fastened on a base plate 12 in such a way that the legs 10a and 10b, which are L-shaped in profile, engage under the base plate 12. The legs 10a and 10b of the frame part 10 each have a longitudinal slot 14 which are penetrated by the legs 16a, 16b of a second rigid frame part 16 which run at right angles to one another. The second frame part 16 forms with the first frame part 10 a rectangular clamping frame, the size of which can be changed by moving the second frame part 16 relative to the first frame part 10.

Auf der Aussenseite der Schenkel 10a, 19b des ersten Rahmenteils 10 ist jeweils eine parallel zu dem Schenkel verlaufende Zugstange 18 vorgesehen, die in U-förmigen Führungsstücken 20 geführt ist und an dem jeweils zugehörigen Schenkel 16a, 16b des zweiten Rahmenteiis angreift. Die Verbindung von Zugstange 18 und Schenkel 16a bzw. 16b ist dabei dergestalt, dass der Schenkel 16a bzw. 16b in seiner Längsrichtung gegenüber der Zugstange verschoben werden kann. Wie aus der Figur ferner hervorgeht, sind die Zugstangen derart orientiert, dass sie sich an der Ecke des ersten Rahmenteils 10 schneiden.On the outside of the legs 10a, 19b of the first frame part 10 there is a pull rod 18 running parallel to the leg, which is guided in U-shaped guide pieces 20 and engages the respectively associated legs 16a, 16b of the second frame part. The connection between tie rod 18 and leg 16a or 16b is such that leg 16a or 16b can be displaced in its longitudinal direction with respect to the tie rod. As can also be seen from the figure, the tie rods are oriented such that they intersect at the corner of the first frame part 10.

Den Ecken des aus den Rahmenteilen 10 und 16 bestehenden Spannrahmens sind Winkelstücke 20' zugeordnet, wobei die Winkelstücke, deren Schenkel sich über einen nur verhältnismässig kurzen Abschnitt der Schenkel 10a, 10b, 16a, 16b erstrecken, an den Ecken der Rahmenteile 10 bzw. 16 starr mit diesen verbunden sind, während die anderen Winkelstücke 20", die den durch die Schnittstellen der Schenkel 10a, 16a bzw. 10b, 16b gebildeten Ecken zugeordnet sind, verschieblich in den Längsschlitzen 14 geführt sind und lose an den Schenkeln 16a, 16b des zweiten Rahmenteils 16 anliegen. Die letzteren Winkelstücke 20" tragen im wesentlichen Umfang mit zu einer rechtwinkeligen Ausrichtung des Spannrahmens bei.Angle pieces 20 'are assigned to the corners of the clamping frame consisting of the frame parts 10 and 16, the angle pieces, the legs of which extend over a relatively short section of the legs 10a, 10b, 16a, 16b, at the corners of the frame parts 10 and 16, respectively are rigidly connected to these, while the other angle pieces 20 ″, which are assigned to the corners formed by the intersections of the legs 10a, 16a and 10b, 16b, are displaceably guided in the longitudinal slots 14 and loosely on the legs 16a, 16b of the second Bearing frame part 16. The latter angle pieces 20 "contribute substantially to the right-angled alignment of the tenter frame.

Auf den nach aussen vorstehenden Abschnitten der Schenkel 16a, 16b des zweiten Rahmenteils 16 sowie der Zugstange 18 sind Spannzwingen 22 angeordnet, die sich auf der Aussenseite der Schenkel 10a, 10b des ersten Rahmenteils 10 abstützen. Mit Hilfe der Spannzwingen 22 kann nun, wie ohne weiteres aus der Figur ersichtlich, das zweite Rahmenteil 16 zum Einspannen eines in der Figur gestrichelt eingezeichneten Rahmens 24 gegenüber dem ersten Rahmenteil 10 derart festgezogen werden, dass der Rahmen von allen Seiten her zusammengepresst wird. Durch die Verwendung der Zugstangen 18 wird dabei sichergestellt, dass die Zugkräfte, die in der Figur durch Pfeile dargestellt sind, im Sinne einer ausgeglichenen Belastung aufgeteilt werden können. Die innenseitig angeordneten Winkelstücke 20', 20", mit denen der eingespannte Rahmen 24 in Anlage kommt, garantieren, dass der rechte Winkel des Rahmens 24 beim Einspannen aufrechterhalten wird, d.h., dass die Ecken des eingespannten Rahmens 24 nicht einer den rechten Winkel des Rahmens 24 deformierenden Belastung unterworfen werden.Clamping clamps 22 are arranged on the outwardly projecting sections of the legs 16a, 16b of the second frame part 16 and the pull rod 18, which are supported on the outside of the legs 10a, 10b of the first frame part 10. With the aid of the clamping clamps 22, the second frame part 16 can now be tightened relative to the first frame part 10 in such a way that the frame is pressed together from all sides, in order to clamp a frame 24 shown in broken lines in the figure. The use of the tie rods 18 ensures that the tensile forces, which are represented by arrows in the figure, can be distributed in the sense of a balanced load. The internally arranged angle pieces 20 ', 20 ", with which the clamped frame 24 comes into contact, guarantee that the right angle of the frame 24 is maintained during clamping, ie that the corners of the clamped frame 24 do not match the right angle of the frame 24 subjected to deforming stress.
