Description

Die Erfindung betrifft eine Strangpreßprofil-Leiste aus Metall für Möbel, insbesondere zur Verwendung als vertikale Stütze bei Industrie-und Büromöbeln.The invention relates to an extruded profile strip made of metal for furniture, in particular for use as a vertical support in industrial and office furniture.

Es sind zwar verschiedene Strangpreßprofil-Leisten aus Metall bekannt, die grundsätzlich auch zum Aufbau von Möbelstücken verwendbar sind ; derartige Leisten sind jedoch wenig dafür geeignet, zur Gestaltung eines universellen Möbelprogramms zu dienen, welches im Gebrauch praktischen Anforderungen ebenso wie ästhetischen Ansprüchen gerecht wird.Various extruded profile strips made of metal are known, which in principle can also be used to build up pieces of furniture; such moldings are, however, not very suitable for the design of a universal furniture program, which meets practical requirements as well as aesthetic demands.

Eine Strangpreß-Hohlprofil-Leiste der eingangs genannten Art ist aus der Druckschrift FR-A-21-80 403 bekannt. Diese bekannte Leiste ist zwar als Hohlprofil ausgebildet, sie weist aber im Hohlraum keine Maßnahmen auf, welche dazu beitragen würden, die Festigkeit des Profils wesentlich zu steigern. Ferner können Stützen, die in das Hohlprofil einhängbar sind, nur stufenweise in ihrer Höhe verstellt werden. Durch die Ausbildung von T-Nuten an den Stirnseiten des Profils wird das ästhetische Aussehen des Profils beeinträchtigt und ein Reinigen erschwert. Diese Profile sind zudem mit scharfen Kanten versehen, an welchen sich Personen stoßen können.An extruded hollow profile bar of the type mentioned is known from the document FR-A-21-80 403. Although this known strip is designed as a hollow profile, it has no measures in the cavity which would contribute to significantly increasing the strength of the profile. Furthermore, the height of supports that can be suspended in the hollow profile can only be adjusted in stages. The formation of T-slots on the end faces of the profile impairs the aesthetic appearance of the profile and makes cleaning more difficult. These profiles are also provided with sharp edges that people can bump into.

Des weiteren ist aus der GB-A-2064305 eine Stütze für Ausstellungsregale bekannt. Die Stütze hat einen quadratischen Querschnitt, dessen Querschnittsform die Aufnahme einer Stütze oder eines Möbelteils in nur einer T-förmigen Nut ermöglicht, welche in einer Seitenfläche des Profils angeordnet ist. Damit ist es infolge der geringen seitlichen Anlagefläche nicht möglich, einem Möbelstück eine erhöhte Seitenstabilität zu geben. Die in den Stirnseiten angebrachten T-förmigen Ausnehmungen bilden wiederum eine gewisse Verletzungsgefahr für Personen und sind einer Reinigung nur schwer zugänglich. Zudem bietet dieses bekannte Profil auch keinen umschlossenen Innenraum, durch welchen Stromkabei oder dergleichen geführt werden könnten.A support for exhibition shelves is also known from GB-A-2064305. The support has a square cross-section, the cross-sectional shape of which makes it possible to accommodate a support or a furniture part in only one T-shaped groove, which is arranged in a side face of the profile. As a result of the small lateral contact surface, it is not possible to give a piece of furniture increased lateral stability. The T-shaped recesses in the end faces in turn create a certain risk of injury for people and are difficult to access for cleaning. In addition, this known profile also does not offer an enclosed interior, through which current cables or the like could be guided.

Schließlich ist aus der US-A-3 824 747 ein mehrstückig aufgebauter Aluminium-Pfeiler bekannt. In seinen langgestreckten Seitenwänden sind keine Befestigungsmöglichkeiten für Möbelteile und keine Maßnahmen zur Festigkeitserhöhung vorgesehen.Finally, a multi-piece aluminum pillar is known from US-A-3 824 747. In its elongated side walls, no fastening options for furniture parts and no measures to increase strength are provided.

Der Erfindung liegt die Aufgabe zugrunde, eine Profil-Leiste der gattungsgemäßen Art zu schaffen, weiche eine große Festigkeit aufweist und bei ästetisch ansprechender Form zugleich vielseitige Befestigungsmöglichkeiten für Möbelteile bietet.The invention has for its object to provide a profile strip of the generic type, which has great strength and at the same time offers versatile fastening options for furniture parts with an aesthetically pleasing shape.

Diese Aufgabe wird gemäß dem kennzeichnenden Merkmal des Anspruches 1 gelöst.This object is achieved according to the characterizing feature of claim 1.

Die erfindungsgemäße Leiste läßt sich praktisch bei allen Schränken, Gestellen, Regalen, Schreibtischen, Arbeitstischen, Labortischen, Besprechungstischen, Schreibmaschinentischen und vielen anderen Möbelstücken als vertikale Stütze verwenden, die vorzugsweise im Bereich der Ecken der Möbelstücke angeordnet ist. Mit Hilfe der T-Nuten lassen sich vertikale Wände und Türen sowie in gleicher Weise auch horizontale Böden oder Platten auf beliebiger Höhe außerordentlich einfach und zugleich besonders fest und stabil anbringen. Da sich die T-Nuten über die gesamte Höhe der Leiste erstrecken, ist auf jedem gewünschten Niveau eine Befestigungsmöglichkeit gegeben.The bar according to the invention can be used as a vertical support in practically all cupboards, racks, shelves, desks, work tables, laboratory tables, meeting tables, typewriter tables and many other pieces of furniture, which is preferably arranged in the area of the corners of the pieces of furniture. With the help of the T-slots, vertical walls and doors as well as horizontal floors or panels can be attached at any height in an extremely simple and at the same time particularly firm and stable. Since the T-slots extend over the entire height of the bar, there is a mounting option at any desired level.

Weiterhin bietet die erfindungsgemäße Leiste den Vorteil, daß eine Platte oder ein Boden, nachdem die Anbringung zunächst auf einer bestimmten Höhe erfolgt ist, ohne Schwierigkeit nachträglich in der Höhe verstellt werden kann.Furthermore, the strip according to the invention has the advantage that a plate or a floor, after the attachment has been carried out first at a certain height, can be adjusted in height without difficulty.

Die Abmessungen der erfindungsgemäßen Leiste sind so gewählt und in ihren Proportionen derart aufeinander abgestimmt, daß für den praktischen Gebrauch die Stabilität und die Festigkeit in ausreichendem Maß gewährleistet sind und dabei zugleich eine ästhetisch besonders ansprechende Formgebung erreicht ist. Insbesondere werden durch die parallel zueinander verlaufenden T-Nuten nicht nur hervorragende Befestigungsmöglichkeiten geboten, sondern es werden vielmehr auch die verhältnismäßig großen Seitenflächen der erfindungsgemäßen Leiste in ästhetischer Hinsicht vorteilhaft unterteilt und gegliedert. Es wird nämlich durch die T-Nuten die Entstehung einer breiteren geschlossenen Fläche verhindert, so daß durch eine Unterbrechung und Gliederung ein besonders vorteilhafter optisch-ästhetischer Eindruck geschaffen wird, ohne dabei die Festigkeit der erfindungsgemäßen Leiste zu beeinträchtigen. Im Gegenteil, durch die nach innen einspringenden T-Nuten wird eine Wand-Versteifung herbeigeführt, die zu einer erheblichen Biegefestigkeit und Knickfestigkeit der Leiste führt. Der optisch- ästhetische Eindruck ebenso wie rein praktische Eigenschaften im Gebrauch werden dadurch vorteilhaft gestaltet, daß im Querschnitt der Leiste zwischen den Längsseiten und den abgerundeten Stirnseiten ein stetiger Übergang vorhanden ist. Dabei kann vorteilhafterweise auch vorgesehen sein, daß der Querschnitt der abgerundeten Stirnseiten halbkreisförmig ausgebildet ist. Die abgerundeten und vorzugsweise halbkreisförmig ausgebildeten Stirnseiten erweisen sich nämlich im praktischen Gebrauch deshalb als besonders vorteilhaft, weil einerseits die Gefahr vermindert wird, daß Personen sich an scharfen Kanten stoßen könnten und weil andererseits die Reinigung erleichtert wird.The dimensions of the strip according to the invention are selected and their proportions are coordinated with one another in such a way that the stability and strength are sufficiently ensured for practical use and at the same time an aesthetically particularly appealing shape is achieved. In particular, the T-grooves running parallel to each other not only offer excellent fastening options, but rather the relatively large side surfaces of the strip according to the invention are also advantageously divided and divided from an aesthetic point of view. It is namely prevented by the T-grooves, the formation of a wider closed surface, so that a particularly advantageous optical-aesthetic impression is created by an interruption and structure, without affecting the strength of the strip according to the invention. On the contrary, the inwardly projecting T-slots provide wall stiffening, which leads to considerable bending strength and kink resistance of the bar. The optical-aesthetic impression as well as purely practical properties in use are advantageously designed in that there is a constant transition in the cross section of the strip between the long sides and the rounded end faces. It can advantageously also be provided that the cross section of the rounded end faces is semicircular. The rounded and preferably semicircular end faces turn out to be particularly advantageous in practical use because on the one hand the risk is reduced that people could bump against sharp edges and on the other hand cleaning is made easier.

Um eine besonders hohe Festigkeit zu erreichen, ist vorgesehen, daß die T-Nuten derart paarweise angeordnet sind, daß jeweils einer T-Nut auf der einen Längsseite eine T-Nut auf der anderen Längsseite direkt gegenübersteht, und daß zwischen den beiden T-Nuten eines T-Nutenpaares wenigstens ein Verbindungssteg vorhanden ist.In order to achieve a particularly high strength, it is provided that the T-slots are arranged in pairs such that a T-slot on one long side is directly opposite a T-slot on the other long side, and that between the two T-slots A pair of T-slots has at least one connecting web.

Die Erfindung sieht vor, daß wenigstens zwischen den beiden T-Nuten eine in der Mitte der Längsseiten angeordneten T-Nutenpaares zwei auf Abstand voneinander angeordnete Verbindungsstege angeordnet sind und daß die einander zugewandten Seiten der Verbindungsstege derart ausgebildet sind, daß eine kreisrunde Öffnung gebildet ist. Die kreisrunde Öffnung des Erfindungsgegenstandes läßt sich zur Befestigung verschiedenster Bauteile bequem verwenden.The invention provides that at least two The two T-grooves are arranged in the middle of the long sides of the pair of T-grooves, two spaced-apart connecting webs are arranged and that the mutually facing sides of the connecting webs are designed such that a circular opening is formed. The circular opening of the subject matter of the invention can be used conveniently for fastening a wide variety of components.

Ausreichende Befestigungsmöglichkeiten ergeben sich dadurch, daß entlang einer Längsseite wenigstens zwei T-Nuten vorhanden sind, insbesondere dann, wenn die Anordnung weiterhin derart getroffen ist, daß die T-Nuten jeweils in dem Endbereich der Längsseiten angeordnet sind, welcher an die abgerundeten Stirnseiten angrenzt.Sufficient fastening options result from the fact that there are at least two T-slots along one long side, in particular if the arrangement is further made such that the T-slots are each arranged in the end region of the long sides which adjoins the rounded end faces.

Die Befestigungsmöglichkeiten für weitere Teile von Möbelstücken können vorzugsweise noch dadurch verbessert werden, daß mittig zwischen zwei im Endbereich der Längsseiten angeordneten T-Nuten jeweils eine weitere T-Nut vorhanden ist.The attachment options for other parts of furniture can preferably be further improved by the fact that a further T-groove is provided in the middle between two T-grooves arranged in the end region of the long sides.

Weitere Befestigungsmöglichkeiten ergeben sich dadurch, daß der Verbindungssteg zwischen den beiden T-Nuten die jeweils im Endbereich der Längsseiten angeordnet sind, zwei klammerartige Ansätze aufweist, die in den durch die abgerundeten Stirnseiten umschlossenen Raum ragen, wodurch aus dem Verbindungssteg und den klammerartigen Anstäzen jeweils eine hufeinsenförmige Querschnittskonfiguration gebildet ist. Dabei kann vorzugsweise vorgesehen sein, daß die klammerartigen Ansätze parallel zu den abgerundeten Stirnseiten angeordnet sind. Dabei kann die Anordnung vorzugsweise so getroffen sein, daß die klammerartigen Ansätze bei halbkreisförmigen Stirnseiten konzentrisch zu den Stirnseiten angeordnet sind.Further fastening options result from the fact that the connecting web between the two T-grooves, which are each arranged in the end region of the long sides, has two clip-like projections which protrude into the space enclosed by the rounded end faces, whereby one each from the connecting web and the clip-like projections hoof-shaped cross-sectional configuration is formed. It can preferably be provided that the clip-like approaches are arranged parallel to the rounded end faces. The arrangement can preferably be such that the bracket-like approaches are arranged concentrically to the end faces in the case of semicircular end faces.

Die Ausnehmungen ebenso wie die Öffnung führen zu einer Materialersparnis bei der Herstellung der erfindungsgemäßen Leiste und erfüllen zugleich den Zweck, zur Befestigung von verschiedenen Bauteilen zu dienen.The recesses as well as the opening lead to material savings in the manufacture of the strip according to the invention and at the same time serve the purpose of fastening various components.

Durch die Formgebung der erfindungsgemäßen Leiste wird eine ausreichende Festigkeit auch dann noch erreicht, wenn die Wandstärke der Hohlprofil-Leiste etwa 2 mm beträgt.Due to the shape of the strip according to the invention, sufficient strength is achieved even if the wall thickness of the hollow profile strip is approximately 2 mm.

Die Erfindung wird nachfolgend beispielsweise anhand der Zeichnung beschrieben ; in dieser zeigt die einzige Figur einen Querschnitt durch eine Strangpreßprofil-Leiste.The invention is described below, for example with reference to the drawing; in this the only figure shows a cross section through an extruded profile strip.

Die in ihrer Gesamtheit mit 10 bezeichnete Strangpreßprofil-Leiste gemäß der Zeichnung hat im Querschnitt die Form eines langgestreckten Rechteckes, an dessen Längsseiten 19 und 20 jeweils drei T-Nuten 11, 13, 15 bzw. 12, 14, 16 ausgebildet sind, wobei die T-Nuten in den Profil-Innenraum einspringen. An die beiden Längsseiten 19 und 20 schließen sich jeweils in einem stetigen Übergang abgerundete Stirnseiten 17 und 18 an. Bei der in der Zeichnung dargestellten Ausführungsform des Erfindungsgegenstandes weisen die beiden Stirnseiten 17 und 18 jeweils halbkreisförmige Wände auf, die tangential in die Längsseiten 19 und 20 übergehen.The generally designated 10 extruded profile strip according to the drawing has in cross section the shape of an elongated rectangle, on the long sides 19 and 20 of which three T-grooves 11, 13, 15 and 12, 14, 16 are formed, respectively Jump T-slots into the profile interior. On the two long sides 19 and 20, rounded end faces 17 and 18 are connected in a continuous transition. In the embodiment of the subject matter shown in the drawing, the two end faces 17 and 18 each have semicircular walls which merge tangentially into the longitudinal sides 19 and 20.

Die T-Nuten sind paarweise zueinander angeordnet, so daß jeweils in den beiden Endbereichen der Längsseiten 19 und 20 ein T-Nuten-Paar 11, 12 bzw. 15, 16 vorhanden ist und ein weiteres T-Nuten-Paar 13, 14 in der Mitte der Längsseiten 19 und 20 vorhanden ist. Zwischen den beiden T-Nuten eines Paares sind jeweils Verbindungsstege 21, 22 bzw. 23 vorhanden. Durch die zwischen den einander gegenüber angeordneten T-Nuten vorgesehenen Verbindungsstege wird die Festigkeit des Strangpreßprofils erheblich erhöht.The T-slots are arranged in pairs to each other, so that in each case in the two end regions of the long sides 19 and 20 there is a pair of T-slots 11, 12 and 15, 16 and another pair of T-slots 13, 14 in the Middle of the long sides 19 and 20 is present. Between the two T-grooves of a pair there are connecting webs 21, 22 and 23, respectively. The strength of the extruded profile is considerably increased by the connecting webs provided between the T-grooves arranged opposite one another.

Der Verbindungssteg zwischen den im mittleren Bereich der Längsseiten 19 und 20 angeordneten T-Nuten 13 und 14 ist unterteilt, so daß zwei Teilstege 22a und 22b entstanden sind. Die einander zugewandten Seiten dieser Teilstege sind derart geformt, daß zwischen diesen beiden Teilstegen eine kreisrunde Öffnung 24 gebildet ist. Diese kreisrunde Öffnung 24 kann zur Aufnahme von mechanischen Befestigungselementen vorteilhaft verwendet werden.The connecting web between the T-grooves 13 and 14 arranged in the central region of the long sides 19 and 20 is subdivided, so that two partial webs 22a and 22b have been created. The mutually facing sides of these partial webs are shaped such that a circular opening 24 is formed between these two partial webs. This circular opening 24 can advantageously be used for receiving mechanical fastening elements.

Auf beiden Seiten des Verbindungssteges 21 sind klammerartige Ansätze 25 und 26 angebracht, so daß aus dem Verbindungssteg 21 und den beiden klammerartigen Ansätzen 25 und 26 eine hufeisenförmige Anordnung gebildet ist. Der Innenraum der hufeisenförmigen Ausnehmung ist als kreisförmige Ausnehmung 31 ausgebildet. Zwischen den beiden freien Schenkeln der Ansätze 25 und 26 ist eine Öffnung vorhanden, die einen zentralen Öffnungswinkel von etwa 60 Grad aufweist. Die kreisförmige Ausnehmung kann beispielsweise zur Aufnahme eines mechanischen Befestigungselementes dienen, wobei es sich als vorteilhaft erweisen kann, daß die beiden Ansätze 25 und 26 auf Grund ihrer Elastizität leicht nach außen federn können. Es kann die kreisförmige Ausnehmung 31 jedoch auch ebenso wie der zwischen den beiden Ansätzen 25 und 26 einerseits und der Stirnseite 17 andererseits gebildete Freiraum zur Aufnahme von Leitungen oder dergleichen verwendet werden.Clamp-like projections 25 and 26 are attached on both sides of the connecting web 21, so that a horseshoe-shaped arrangement is formed from the connecting web 21 and the two clamp-like projections 25 and 26. The interior of the horseshoe-shaped recess is designed as a circular recess 31. Between the two free legs of the lugs 25 and 26 there is an opening which has a central opening angle of approximately 60 degrees. The circular recess can serve, for example, to accommodate a mechanical fastening element, it being advantageous that the two lugs 25 and 26 can spring slightly outwards due to their elasticity. However, the circular recess 31 can also be used for receiving lines or the like, as can the free space formed between the two shoulders 25 and 26 on the one hand and the end face 17 on the other hand.

Eine entsprechende Anordnung, wie sie durch den Verbindungssteg 21, die Ansätze 25 und 26 sowie die kreisförmige Ausnehmung 31 gebildet ist, ist auf der gegenüberliegenden Seite des Profils durch den Verbindungssteg 23, die Ansätze 27 und 28 und die dazwischen gebildete kreisförmige Ausnehmung 32 vorhanden.A corresponding arrangement, as it is formed by the connecting web 21, the lugs 25 and 26 and the circular recess 31, is provided on the opposite side of the profile by the connecting web 23, the lugs 27 and 28 and the circular recess 32 formed therebetween.

Besonders große Freiräume 29 und 30 sind jeweils zwischen benachbarten Paaren von T-Nuten ausgebildet und können zur Aufnahme von elektrischen Kabeln oder sonstigen Versorgungsleitungen verwendet werden. Die beiden Freiräume 29 und 30 weisen im wesentlichen eine Rechteck-Konfiguration auf, wobei sich an den Rechteck-Querschnitt jeweils eine Nische anschließt, die sich in den Bereich zwischen den beiden T-Nuten 11 und 12 einerseits bzw. 15 und 16 andererseits erstreckt.Particularly large free spaces 29 and 30 are each formed between adjacent pairs of T-slots and can be used to hold electrical cables or other supply lines. The two free spaces 29 and 30 essentially have a rectangular configuration, with a rectangle each adjoining the rectangular cross section, which extends into the area between the two T-grooves 11 and 12 on the one hand and 15 and 16 on the other.

Der in der Zeichnung dargestellte Querschnitt der erfindungsgemäßen Leiste ermöglicht nicht nur vielfältige Anwendungsmöglichkeiten auf Grund seiner räumlichen Gestaltung und Gliederung, es ist vielmehr auch ein wesentlicher Aspekt der Erfindung, daß durch die oben beschriebene Querschnittskonfiguration eine besonders hohe Biegefestigkeit und eine entsprechend hohe Knickfestigkeit gewährleistet sind.The cross section shown in the drawing The strip according to the invention not only enables a wide range of applications due to its spatial design and structure, it is also an essential aspect of the invention that the cross-sectional configuration described above ensures a particularly high flexural strength and a correspondingly high kink resistance.
