Die Erfindung bezieht sich auf das Gebiet der Möbelindustrie. Sie betrifft eine Vorrichtung und ein Verfahren zur Befestigung einer hohlen Rückenlehne für Sitzmöbel.The invention relates to the field of the furniture industry. It affects one Device and method for attaching a hollow backrest for Seating.

Stand der TechnikState of the art

Es ist bekannt, als Rückenlehnen für Sitzmöbel geblasene Kunststoffhohlkörper zu verwenden, welche je nach gewünschter Ausführung der Sitzmöbel gepolstert oder ungepolstert eingesetzt werden können.It is known as a backrest for seating blown plastic hollow body to use, which is padded depending on the desired version of the seating or can be used without padding.

Bisher werden derartige hohle Blasformteile aus Kunststoff mit Einlegemuttern versehen, welche in eine Wand des Hohlkörpers eingelassen werden. Diese Einlegemuttem werden dann zum Verschrauben der Kunststoffteile mit dem Rohrgestell verwendet, so dass eine kraftschlüssige Verbindung entsteht.So far, such hollow blow molded parts made of plastic with insert nuts provided, which are embedded in a wall of the hollow body. These motherfuckers are then used to screw the plastic parts to the tubular frame used so that a positive connection is created.

Die Nachteile dieses bekannten Standes der Technik bestehen darin, daß das Werkzeug zur Einbringung der Einlegemuttem störanfällig ist, daß die Herstellungszeit der Kunststoffhohlkörper durch diesen zusätzlichen Verfahrensschritt verlängert wird, und schließlich der Verfahrensablauf insofern gestört wird, als daß das Blasformen ein kontinuierlicher Vorgang ist, das Einsetzen der Einlegemuttern aber diskontinuierlich erfolgen muß. Um Kräfte abzuleiten müssen außerdem generell mehrere Verschraubungen vorgesehen werden, damit die Beanspruchung der einzelnen Eihfeemuttcr nicht zu hoch wird.The disadvantages of this known prior art are that Tool for inserting the insert nut is prone to failure that the manufacturing time the plastic hollow body through this additional process step is extended, and finally the process is disrupted in that that blow molding is a continuous process, inserting the insert nuts but must be done discontinuously. To derive forces also have to Generally several screw connections are provided so that the stress the individual egg yeast nut does not become too high.

Darstellung der ErfindungPresentation of the invention

Die Erfindung versucht, die beschriebenen Nachteile des Standes der Technik zu vermeiden. Ihr liegt die Aufgabe zugrunde, eine einfache Vorrichtung und ein leicht ausführbares Verfahren zur Befestigung einer aus einem Blasformteil gebildeten hohlen Rückenlehne für Sitzmöbel zu schaffen, welche sich gegenüber dem bekannten Stand der Technik durch einen verringerten Zeit- und Kostenaufwand sowie eine verbesserte Qualität der Befestigung auszeichnet, wobei die Befestigung beinahe unsichtbar sein soll.The invention attempts to overcome the disadvantages of the prior art described avoid. It is based on the task of a simple device and a easily executable method for attaching a blow molded part to create hollow backrest for seating, which face each other the known prior art through a reduced expenditure of time and money as well as an improved quality of attachment, the Attachment should be almost invisible.

Erfindungsgemäß wird dies bei einer Vorrichtung gemäß Oberbegriff des Patentanspruches 1 dadurch errreicht, daß einerseits der Rahmen zwecks Aufnahme der Rückenlehne einen am Rahmen fest angebrachten, in die hohle Rückenlehne einschiebbaren Lagerbügel aufweist, und daß andererseits eine Klemmleiste vorgesehen ist, welche einen Formschluß und einen Kraftschluß zwischen der Rückenlehne und dem Rahmen herstellt.According to the invention, this becomes in a device according to the preamble of the claim 1 thereby achieved that on the one hand the frame for the purpose of recording the backrest one firmly attached to the frame, into the hollow backrest insertable bearing bracket, and that on the other hand a terminal block is provided, which has a positive connection and a frictional connection between the Backrest and the frame manufactures.

Die Vorteile der Erfindung bestehen darin, daß eine vergleichsweise einfache Befestigung der Rückenlehne am Rahmen erfolgt, die aber sehr stabil ist. Der Lagerbügel nimmt einerseits die Anlehnkräfte auf und dient andererseits gemeinsam mit der Klemmleiste zur Befestigung der Rückenlehne.The advantages of the invention are that they are comparatively simple The backrest is attached to the frame, but it is very stable. The Bearing bracket on the one hand absorbs the leaning forces and on the other hand serves together with the terminal block for fastening the backrest.

Es ist zweckmäßig, wenn die Klemmleiste und der Rahmen mittig jeweils eine Öffnung zur Aufnahme eines Verbindungsstückes, vorzugsweise einer Schraube oder eines Blindnietes aufweisen. Auf diese Weise läßt sich eine sehr gute kraftschlüssige Verbindung zwischen der hohlen Rückenlehne und dem Rahmen des Sitzmöbels herstellen. It is useful if the terminal block and the frame in the middle each Opening for receiving a connector, preferably a screw or have a blind rivet. In this way, a very good frictional Connection between the hollow backrest and the frame of the Manufacture seating furniture.

Weiterhin ist es von Vorteil, wenn der Lagerbügel zumindestens teilweise mit einem Dämpfungselement ummantelt ist. Das Dämpfungselement besteht dabei aus einem Ausgleichsmaterial und bewirkt vorteilhaft, daß beim Anlehnen eine Geräuschbildung vermieden und ein weicher Anschlag nach hinten sichergestellt wird.Furthermore, it is advantageous if the bearing bracket at least partially with is encased in a damping element. The damping element is there made of a compensating material and advantageously causes a Noise is avoided and a soft stop to the rear is ensured becomes.

Das erfindungsgemäße Verfahren zur Befestigung der Vorrichtung ist dadurch gekennzeichnet, daß die hohle Rückenlehne mit ihrer unteren, partiell offenen Seite zunächst teilweise über den Lagerbügel geschoben wird, danach die Klemmleiste in die untere Seite der Rückenlehne so eingelegt wird, daß beim nachfolgenden kompletten Überschieben der hohlen Rückenlehne über den Lagerbügel die Öffnungen im Rahmen und in der Klemmleiste nahezu deckungsgleich aufeinander zu liegen kommen und anschließend durch die Öffnungen das Verbindungsteil geschoben und befestigt wird.The method according to the invention for fastening the device is thereby characterized in that the hollow backrest with its lower, partially open Side is partially pushed over the bracket, then the Terminal strip is inserted into the lower side of the backrest so that when then completely push the hollow backrest over the bearing bracket the openings in the frame and in the terminal strip are almost congruent come to lie on top of each other and then through the openings Connection part is pushed and fastened.

Weg zur Ausführung der ErfindungWay of carrying out the invention

Nachfolgend wird die Erfindung anhand eines Ausführungsbeispieles und der Figur näher erläutert. The invention based on an embodiment and the Figure explained in more detail.

Die einzige Figur zeigt in perspektivischer Ansicht einen Teil eines metallischen Rohrrahmens 1 für einen Stuhl mit einer an diesem Rahmen 1 zu befestigenden hohlen Rückenlehne 2 und den dafür notwendigen Zusatzteilen. Der Zusammenbau der Einzelteile ist mit gestrichelten Pfeilen in der Figur angedeutet.The single figure shows a perspective view of part of a metallic Tubular frame 1 for a chair with a to be attached to this frame 1 hollow backrest 2 and the necessary additional parts. The assembly the individual parts are indicated by dashed arrows in the figure.

Die Rückenlehne 2 besteht aus Kunststoff und ist als Blasformteil gefertigt. Aus der Figur geht nicht hervor, daß die untere schmale Seite 7 der Rückenlehne überwiegend offen ausgebildet ist und lediglich von der vorderen und der hinteren Seite der Rückenlehne 2 jeweils ein schmaler Rand zur Seite 7 umgebogen ist. Die anderen Seiten des Blasformteiles 2 sind geschlossen. Die Form der unteren Seite 7 der Lehne 2 ist der Form des Rahmens 1 angepaßt, so daß bei einer Befestigung der Lehne am Rahmen ein Formschluß gegeben ist.The backrest 2 is made of plastic and is manufactured as a blow molded part. Out the figure does not show that the lower narrow side 7 of the backrest is predominantly open and only from the front and rear Side of the backrest 2 each has a narrow edge bent to the side 7. The other sides of the blow molded part 2 are closed. The shape of the bottom Page 7 of the backrest 2 is adapted to the shape of the frame 1, so that at one Attachment of the backrest to the frame is given a positive fit.

Am Rahmen 1 ist in dem Bereich, in welchem die Rückenlehne 2 angebracht werden soll, ein u-förmiger Lagerbügel 3 aus Metall befestigt. In vorliegenden Ausführungsbeispiel sind die beiden Schenkel des Lagerbügels 3 an ihren offenen Enden mit dem Rahmen 1 verschweißt. Der die Schenkel verbindende Quersteg des Lagerbügels 3 ragt dabei nach oben. In der Mitte des Quersteges ist um den Lagerbügel 3 herum ein Dämpfungselement 4, welches aus einem Ausgleichsmaterial besteht, angebracht. Der Lagerbügel 3 dient dazu, die Anlehnkräfte aufzunehmen. Durch das Dämpfungselement 4 wird eine Geräuschbildung beim Anlehnen vermieden und ein weicher Anschlag nach hinten sichergestellt.The frame 1 is in the area in which the backrest 2 is attached should, a u-shaped bracket 3 made of metal attached. In the present embodiment are the two legs of the bracket 3 at their open Welded ends to the frame 1. The crossbar connecting the legs the bracket 3 protrudes upwards. In the middle of the crossbar is around Bearing bracket 3 around a damping element 4, which is made of a compensating material exists, attached. The bracket 3 serves to absorb the leaning forces. The damping element 4 causes noise when leaning avoided and a soft stop to the rear ensured.

In der Figur ist außerdem eine Klemmleiste 5 dargestellt. Die Klemmleiste 5 ist ein gebogenes rinnenartiges Blechstück, dessen Krümmung einen Innenradius aufweist, welcher etwa dem Außenradius des Rohrrahmens 1 entspricht. In der Mitte der Klemmleiste 5 ist eine Bohrung 8 angebracht, welche ein Innengewinde aufweist. Im Rohrrahmen 1 ist mittig zwischen den beiden Schenkeln des Lagerbügels 3 eine durchgehende Öffnung 9 vorgesehen. Die Öffnungen 8 und 9 dienen der Aufnahme eines Verbindungsstückes 6. Das Verbindungsstück 6 ist im vorliegenden Ausführungsbeispiel ein Schraube. Es könnte aber anstelle der Schraube z. B. auch ein Blindniet verwendet werden.In the figure, a terminal block 5 is also shown. The terminal block 5 is a curved gutter-like piece of sheet metal, the curvature of which has an inner radius, which corresponds approximately to the outer radius of the tubular frame 1. In the middle the terminal strip 5 has a bore 8 which has an internal thread. In the tubular frame 1 is centered between the two legs of the bracket 3 a through opening 9 is provided. The openings 8 and 9 serve the inclusion of a connector 6. The connector 6 is in present embodiment a screw. But instead of Screw z. B. a blind rivet can also be used.

Die beschriebene erfindungsgemäße Vorrichtung wird folgendermaßen zusammengebaut Die hohle Rückenlehne 2 wird zunächst mit ihrer unteren, partiell offenen Seite 7 teilweise über den Lagerbügel 3 geschoben, so daß sich das Dämpfungselement 4 im Inneren der hohlen Rückenlehne 2 befindet. Nun wird die Klemmleiste 5 in die untere Seite 7 der Rückenlehne 2 eingeschoben und so gedreht, daß einerseits ihre gewölbte Fläche nach oben zeigt, und andererseits die Klemmleiste 5 auf den seitlichen Rändern der Seite 7 innen aufliegt. Die Klemmleiste 5 wird so verschoben und justiert, daß beim nun folgenden kompletten Überschieben der Lehne 2 über den Lagerbügel 3 die Öffnung 9 im Rohrrahmen 1 und die Öffnung 8 mit der Gewindebohrung in der Klemmleiste 5 annähernd deckungsgleich aufeinander zu liegen kommen. Abschließend wird durch die Öffnung 9 eine Schraube 6 eingeführt und mit dem Gewindedurchzug 8 verschraubt, so daß nunmehr der Rahmen 1, die Klemmleiste 5 und die Rückenlehne 2 fest miteinander verbunden sind. Die Klemmleiste 5 gewährleistet einerseits einen Formschluß zwischen dem Blasformteil 2 und dem Rahmen 1, andererseits auf Grund der Verschraubung einen Kraftschluß. Somit ist die Befestigungsqualität sehr gut. Ein weiterer Vorteil der Erfindung besteht darin, daß die Befestigung beinahe unsichtbar geschieht.The described device according to the invention is assembled as follows The hollow backrest 2 is initially with its lower, partial open side 7 partially pushed over the bracket 3, so that the Damping element 4 is located inside the hollow backrest 2. Now the Terminal strip 5 inserted into the lower side 7 of the backrest 2 and turned so that on the one hand its curved surface points upwards and on the other hand the Terminal strip 5 rests on the side edges of page 7 on the inside. The terminal block 5 is shifted and adjusted so that the next complete Push the back 2 over the bracket 3, the opening 9 in the tubular frame 1 and the opening 8 with the threaded hole in the terminal block 5 approximately come to lie congruently on one another. Finally, through the opening 9 a screw 6 is inserted and screwed to the threaded passage 8, so that now the frame 1, the terminal block 5 and the backrest 2 fixed are interconnected. The terminal block 5 ensures one hand Form fit between the blow molded part 2 and the frame 1, on the other hand Due to the screw connection a frictional connection. So the quality of the fastening very good. Another advantage of the invention is that the attachment happens almost invisibly.

Selbstverständlich ist die Erfindung nicht auf das beschriebene Ausführungsbeispiel beschränkt. So kann der erforderliche Kraftschluß zwischen Rahmen 1, Klemmleiste 3 und Rückenlehne 2 auch mittels Einbringung eines Blindnietes anstelle einer Verschraubung realisiert werden. Neben der beschrieben Verwendung einer ungepolsterten Rückenlehne ist die Erfindung natürlich auch zur Befestigung einer gepolsterten hohlen Rückenlehne geeignet. Bei diesen beiden Varianten ist lediglich der Zwischenraum zwischen den Blasformteilen und dem Rahmen unterschiedlich groß. Dies wird durch die Klemmleiste ausgeglichen. Of course, the invention is not based on the described embodiment limited. So the required adhesion between frame 1, Terminal strip 3 and backrest 2 also by inserting a blind rivet instead of a screw connection. In addition to the use described an unpadded backrest is of course also the invention Attachment of a padded hollow backrest suitable. With these two The only variant is the space between the blow molded parts and the Different sizes of frames. This is compensated for by the terminal block.
