Description

TECHNISCHES GEBIETTECHNICAL AREA

Die Erfindung betrifft eine Rückenlehne nach dem Oberbegriff des Anspruchs 1, insbesondere für den Bürobereich.The invention relates to a backrest according to the preamble of claim 1, in particular for the office area.

Bei solchen Rückenlehnen ist es nicht nur wichtig, daß sie kostengünstig in großen Stückzahlen herzustellen sind, sondern sie müssen auch im Hinblick auf Transport, Lagerung, Montage und Demontage, Ästhetik und schließlich auch Entsorgbarkeit optimiert werden. Des weiteren sollen sie Variationen bei der Zusammenstellung der einzelnen Bauteile des Sitzmöbels im Sinne eines Baukastensystems ermöglichen.With such backrests, it is not only important that they can be produced inexpensively in large quantities, but they also have to be optimized with regard to transport, storage, assembly and disassembly, aesthetics and finally also disposability. Furthermore, they should enable variations in the composition of the individual components of the seating furniture in the sense of a modular system.

STAND DER TECHNIKSTATE OF THE ART

Bei den heute auf dem Markt befindlichen Rückenlehnen sind insbesondere zwei Arten zur Befestigung an den Holmen des Standgestells bekannt:In the backrests on the market today, two types of attachment to the uprights of the stand frame are known in particular:

Entweder weist die Rückenlehne zwei parallel verlaufende zylindrische Ausnehmungen auf, mittels derer die Lehne engsitzend auf die Holme aufgeschoben wird.Either the backrest has two parallel cylindrical recesses, by means of which the backrest is pushed tightly onto the bars.

Oder die Rückenlehne wird an die Holme angeschraubt.Or the backrest is screwed onto the bars.

Die erstgenannte Lösung hat insbesondere den Nachteil, daß die Ausnehmungen parallel verlaufen müssen, weil sonst kein stramm sitzendes Aufschieben der Lehne auf die Holme möglich ist. Des weiteren sind auch enge Passungen und festes Material erforderlich, damit die Lehne auch noch nach langem intensiven Gebrauch fest sitzt.The first-mentioned solution has the particular disadvantage that the recesses must run parallel, because otherwise it is not possible to push the backrest tightly onto the bars. Furthermore, tight fits are also tight Material required so that the backrest remains firmly in place even after long, intensive use.

Die zweitgenannte Lösung hat insbesondere die Nachteile, daß zur Montage Werkzeug erforderlich ist, daß die sichtbaren Schrauben ästhetisch stören, und daß ein relativ voluminöser Aufbau der Lehne unvermeidbar ist, da unvermeidbar eine gewisse minimale Materialstärke für die Schraubengewinde erforderlich ist.The second-mentioned solution has the disadvantages in particular that tools are required for assembly, that the visible screws are aesthetically disturbing, and that a relatively voluminous structure of the backrest is unavoidable since a certain minimum material thickness is inevitably required for the screw thread.

FR 982 302 also describes a specially designed construction for the backrest of a piece of seating.

DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION

Es ist die Aufgabe der Erfindung, Rückenlehnen der bekannten Arten dahingehend zu verbessern, daß sie eine geringe Bauhöhe, also einen flachen Aufbau, und ein kompaktes Volumen ermöglichen, kostengünstig herzustellen, leicht und insbesondere werkzeugfrei zu montieren und demontieren sowie platzsparend zu lagern sind, sie ein ästhetisch ansprechendes Design erlauben, und sie auch mit geringstmöglichem Aufwand zu entsorgen sind.It is the object of the invention to improve backrests of the known types such that they have a low overall height, that is to say a flat structure, and a compact volume, are inexpensive to manufacture, easy to assemble and disassemble, in particular without tools, and are space-saving to store allow an aesthetically pleasing design, and they can be disposed of with the least possible effort.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 und der Unteransprüche gelöst.This object is achieved by the features of claim 1 and the subclaims.

Der Kern der Erfindung besteht darin, daß die erfindungsgemäße Rückenlehne beidseits von Zahnleisten flankierte Ausformungen aufweist, in welche die Enden der Träger-Holme eingelegt werden, und die eingelegten Holme dann mittels Rastschiebern verriegelt werden.The essence of the invention is that the backrest according to the invention has flanks flanked on both sides by toothed strips, into which the ends of the Carrier spars are inserted, and the inserted spars are then locked using locking slides.

Dadurch wird es insbesondere möglich, die Holme in Richtungen laufen zu lassen, die vom ästhetischen oder technischen Design her erwünscht sind, und die Lehnen werkzeugfrei zu montieren und zu demontieren. Des weiteren ist ein flacher und kompakter Aufbau gegeben, und wegen völlig fehlender Metallteile ist auch eine Entsorgung vereinfacht. Da an den Holmen keine Änderungen notwendig sind, können auch anders konstruierte Lehnen montiert werden, sodaß auch die gewünschte Variationsmöglichkeit hinsichtlich der eingesetzten Bauteile gegeben ist.This makes it possible, in particular, to let the spars run in directions that are desired in terms of aesthetic or technical design, and to assemble and disassemble the backrests without tools. Furthermore, a flat and compact structure is provided, and disposal is simplified because of the completely missing metal parts. Since no changes are necessary to the spars, differently designed backrests can also be installed, so that the desired variation in the components used is also possible.

WEGE ZUR AUSFÜHRUNG DER ERFINDUNGWAYS OF CARRYING OUT THE INVENTION

Fig.1 zeigt die Trägerschale 1 einer Rückenlehne für ein Sitzmöbel. Diese Trägerschale besteht zum Beispiel aus Polypropylen. Sie ist an den Holmen 2 des Standgestelles eines Stuhles zu befestigen.1 shows the carrier shell 1 of a backrest for seating. This carrier shell is made of polypropylene, for example. It is to be attached to the spars 2 of the stand frame of a chair.

Die Trägerschale 1 weist Ausformungen 3 mit der Form der Holme 2 auf. Beidseits dieser Ausformungen 3 sind an der Trägerschale 1 Zahnleisten 4 angebracht.The carrier shell 1 has formations 3 with the shape of the spars 2. On both sides of these formations 3 1 toothed strips 4 are attached to the carrier shell.

Des weiteren sind Rastschieber 5 vorgesehen. Diese Rastschieber 5, die zum Beispiel aus Polypropylen bestehen, sind mit Öffnungen 6 versehen, die mit den Zähnen 7 der Zahnleisten 4 korrespondieren.Furthermore, locking slide 5 are provided. This locking slide 5, which consist for example of polypropylene, are provided with openings 6 which correspond to the teeth 7 of the toothed strips 4.

An der linken Ausformung 3 in der Fig.1 ist gezeigt, wie der Rastschieber 5 in Richtung des gezeichneten Pfeils auf die Zahnleisten 4 aufgesetzt werden kann. An der rechten Ausformung 3 ist der Rastschieber 5 auf die Zahnleisten 4, von denen im Bild nur die Zähne 7 zu sehen sind, aufgesetzt. Wie in dem linken Teil der Fig.2 zu sehen ist, weisen die Zähne 7 der Zahnleisten 4 oben waagrecht nach außen gerichtete Nasen 8 auf. Im rechten Teil der Fig.2 sieht man, daß die Öffnungen 6 in den Rastschiebern 5 in ihrem oberen Teil Verengungen haben, sodaß eine Öffnung 6 insgesamt in etwa eine L-Form hat. Die Öffnungen 6 sind derart dimensioniert, daß die Nasen 8 der Zähne 7 der Zahnleisten 4 durch die breiten Teile der Öffnungen 6 hindurchtreten können, bei den Verengungen 9 jedoch nicht.1 shows how the latching slide 5 can be placed on the toothed strips 4 in the direction of the arrow shown. On the right-hand formation 3, the locking slide 5 is placed on the toothed strips 4, of which only the teeth 7 can be seen in the picture. As can be seen in the left part of FIG. 2, the teeth 7 of the toothed strips 4 have lugs 8 which are horizontally directed outwards at the top. In the right part of FIG. 2 you can see that the openings 6 in the locking slides 5 have constrictions in their upper part, so that an opening 6 has an overall approximately L-shape. The openings 6 are dimensioned such that the lugs 8 of the teeth 7 of the toothed strips 4 can pass through the wide parts of the openings 6, but not with the constrictions 9.

Aus Fig.2 ist auch ersichtlich, daß an der Trägerschale 1 in den Ausformungen 3 Zapfen 10 angebracht sind. Diese Zapfen 10 korrespondieren zu Bohrungen in den Holmen 2.From Figure 2 it can also be seen that 3 pins 10 are attached to the carrier shell 1 in the formations. These pins 10 correspond to bores in the spars 2.

Die Funktion einer Rückenlehne nach der Erfindung ist nun wie folgt:The function of a backrest according to the invention is now as follows:

Zur Montage wird die Trägerschale 1 mit den Ausformungen 3 auf die Holme 2 aufgesetzt. Dabei rasten die Zapfen 10 in (nicht gezeigte) Bohrungen der Holme 2 ein. Sodann werden die beiden Rastschieber 5 mit den breiten Teilen ihrer Öffnungen 6 über die Zähne 7 der Zahnleisten 4 geführt.For assembly, the carrier shell 1 with the formations 3 is placed on the spars 2. The pins 10 snap into bores in the spars 2 (not shown). Then the two locking slides 5 are guided with the wide parts of their openings 6 over the teeth 7 of the toothed strips 4.

Danach erfolgt eine Verschiebung der Rastschieber 5 in Richtung des bei der rechten Ausformung 3 gezeigten Pfeiles nach unten, sodaß die Zähne 7 der Zahnleisten 4 in die Verengungen 9 der Öffnungen 6 eintreten und die Nasen 8 den Rastschieber 5 verriegeln, wodurch dann die ganze Trägerschale 1 an den Holmen 2 fixiert ist.This is followed by a shift of the locking slide 5 in the direction of the arrow shown in the right-hand formation 3, so that the teeth 7 of the toothed strips 4 enter the constrictions 9 of the openings 6 and the lugs 8 lock the locking slide 5, as a result of which the entire carrier shell 1 is fixed to the spars 2.

Um die Rastschieber 5 gegen ein unbeabsichtigtes Entriegeln zu sichern, sind zwei Möglichkeiten vorgesehen:In order to secure the locking slide 5 against unintentional unlocking, two options are provided:

Wenn die Trägerschale 1 mit einer komplementären, nicht gezeigten Schale abgeschlossen wird, welche dann das Rückenpolster trägt, so ist es vorteilhaft, in dieser Polsterschale Ausnehmungen für die Rastschieber 5 vorzusehen, in welchen nach der Verbindung der beiden Schalen die Rastschieber 5 unverschiebbar festliegen.If the carrier shell 1 is completed with a complementary shell, not shown, which then carries the back cushion, it is advantageous to provide recesses for the locking slide 5 in this cushion shell, in which the locking slide 5 are immovably fixed after the connection of the two shells.

Es ist jedoch auch oder zusätzlich möglich, die Rastschieber 5 mit wie in Fig.2 gezeigten Zungen 11 zu versehen, die an ihrem Ende Zapfen 12 tragen: Diese Zapfen 12 gleiten dann beim verriegelnden Verschieben der Rastschieber 5 über die Holme 2, bis sie schließlich in die Öffnungen 13 der Holme 2 einrasten und die Rastschieber 5 gegen unbeabsichtigtes entriegelndes Verschieben sichern.However, it is also or additionally possible to provide the locking slides 5 with tongues 11 as shown in FIG. 2, which have pins 12 at their ends: these pins 12 then slide over the bars 2 when the locking slides 5 are moved in a locking manner until they finally engage in the openings 13 of the spars 2 and secure the locking slides 5 against unintentional unlocking shifting.

Die Öffnungen 13 in den Holmen 2 können übrigens serienmäßig vorgesehen werden, um dann gegebenenfalls für die Befestigung einer Lehne mittels Schrauben zu dienen.The openings 13 in the spars 2 can, by the way, be provided in series, in order then to serve, if necessary, for fastening a backrest by means of screws.

Die in Fig.1 gezeigten, nicht mit Bezugszahlen versehenen Elemente dienen zur Verbindung der Trägerschale 1 mit einer komplementären Polsterschale, wie dies in einer anderen, früher eingereichten Patentanmeldung der gleichen Anmelderin mit dem Titel "Bauteil für den Sitz oder die Lehne eines Sitzmöbels" beschrieben ist.The elements shown in FIG. 1, not provided with reference numbers, serve to connect the carrier shell 1 to a complementary cushion shell, as described in another, previously filed patent application by the same applicant with the title “component for the seat or the back of a piece of seating furniture” is.
