Die Befestigungsstrebe des Gestells ist bevorzugt rohr- oder stangenförmig ausgestaltet, bevorzugt mit einer im Wesentlichen kreisrunden Querschnittsform. Das Material des Gestells und seiner Befestigungsstrebe ist grundsätzlich beliebig, bevorzugt ausgewählt aus Metall, Kunststoff und Holz. Das Material der Sitzschale ist grundsätzlich beliebig, bevorzugt ausgewählt aus Kunststoff und Holz, vorzugsweise als Kunststoff-Blasformschale gefertigt. Das Material der Klemmleiste ist grundsätzlich beliebig, bevorzugt Metall oder Kunststoff.The fastening strut is preferably an integral part of the frame. The mounting strut of the frame is preferably tubular or rod-shaped, preferably with an essentially circular cross-sectional shape. The material of the frame and its fastening strut is basically arbitrary, preferably selected from metal, plastic and wood. The material of the seat shell is basically arbitrary, preferably selected from plastic and wood, preferably made as a plastic blow molded shell. The material of the terminal block is basically arbitrary, preferably metal or plastic.
In einer Ausgestaltung der Erfindung weist der Befestigungsabschnitt des Aufnahmeprofils ein erstes Führungselement auf, das im Wesentlichen parallel zur Längsrichtung des Befestigungsabschnitts verläuft, und weist die Klemmleiste ein zweites Führungselement auf, das im Wesentlichen parallel zur Längsrichtung des Befestigungsabschnitts verläuft und das mit dem ersten Führungselement am Befestigungsabschnitt in der Endposition der Klemmleiste im Befestigungsabschnitt in Eingriff steht. Durch das Ineinandergreifen der beiden Führungselemente wird die Klemmleiste auf einfache Weise in der Richtung senkrecht zur Ebene der Sitzschale im Befestigungsabschnitt des Aufnahmeprofils fixiert. Das erste Führungselement erstreckt sich wahlweise über die gesamte Länge, über eine Teillänge oder abschnittweise über mehrere Teillängen des Befestigungsabschnitts. Das zweite Führungselement erstreckt sich wahlweise über die gesamte Länge, über eine Teillänge oder abschnittweise über mehrere Teillängen der Klemmleiste.In one embodiment of the invention, the fastening section of the receiving profile has a first guide element that runs essentially parallel to the longitudinal direction of the fastening section, and the clamping strip has a second guide element that essentially parallel to the longitudinal direction of the fastening section runs and which is in engagement with the first guide element on the fastening section in the end position of the terminal block in the fastening section. The interlocking of the two guide elements fixes the terminal strip in a simple manner in the direction perpendicular to the plane of the seat shell in the fastening section of the receiving profile. The first guide element optionally extends over the entire length, over a partial length or in sections over several partial lengths of the fastening section. The second guide element optionally extends over the entire length, over a partial length or in sections over several partial lengths of the terminal strip.
Vorzugsweise steht das zweite Führungselement an der Klemmleiste mit dem ersten Führungselement am Befestigungsabschnitt auch schon während des Einschiebens der Klemmleiste in den Befestigungsabschnitt in Eingriff. Auf diese Weise kann die Montage der Klemmleiste vereinfacht oder unterstützt werden.The second guide element on the terminal strip is preferably already engaged with the first guide element on the fastening section while the terminal block is being pushed into the fastening section. In this way, the assembly of the terminal block can be simplified or supported.
In einer Ausgestaltung der Erfindung weist der Befestigungsabschnitt des Aufnahmeprofils ein erstes Rastelement auf und weist die Klemmleiste ein zweites Rastelement auf, das mit dem ersten Rastelement am Befestigungsabschnitt in der Endposition der Klemmleiste im Befestigungsabschnitt in Eingriff steht, um die Klemmleiste in der Längsrichtung des Befestigungsabschnitts zu verrasten.In one embodiment of the invention, the fastening section of the receiving profile has a first latching element and the clamping bar has a second latching element which engages with the first latching element on the fastening section in the end position of the clamping bar in the fastening section in order to close the clamping bar in the longitudinal direction of the fastening section latch.
Das erfindungsgemäße Befestigungskonzept für das Gestell am Sitz ermöglicht es, dass vorzugsweise die Befestigungsstrebe des Gestells und die Klemmleiste in dem Aufnahmeprofil der Sitzschale eingebettet sind. D.h. weder die Befestigungsstrebe noch die Klemmleiste ragen merklich aus der Unterseite der Sitzschale heraus. Dies hat den Vorteil, dass bei bestimmten Gestellformen wie beispielsweise mit Stuhlbeinen in C-Form ein Stapeln mehrerer Stühle übereinander und/oder ein Aufsetzen eines Stuhls mit seinem Sitz auf eine Tischplatte (sog. "Aufstuhlen") problemlos und ohne die Gefahr einer Beschädigung des unteren Stuhls bzw. der Tischplatte oder der Klemmleisten möglich sind. Hierzu sind lediglich eine ausreichend große Dicke der Sitzschale und eine ausreichend große Tiefe des Aufnahmeprofils in der Sitzschalenunterseite vorzusehen.The fastening concept according to the invention for the frame on the seat enables the fastening strut of the frame and the terminal strip to be preferably embedded in the receiving profile of the seat shell. I.e. neither the fastening strut nor the terminal strip protrude noticeably from the underside of the seat shell. This has the advantage that with certain frame shapes such as, for example, with chair legs in a C-shape, stacking several chairs one above the other and / or placing a chair with its seat on a table top (so-called “chairing”) is problem-free and without the risk of damaging the lower chair or the table top or the terminal strips are possible. For this purpose, only a sufficiently large thickness of the seat shell and a sufficiently large depth of the receiving profile in the underside of the seat shell should be provided.
In einer Ausgestaltung der Erfindung weist die Klemmleiste an ihrer der Sitzschale zugewandten Seite ein Aufnahmeprofil auf, das parallel zur Längsrichtung des Befestigungsabschnitts verläuft und einen Umfangsabschnitt der Befestigungsstrebe formschlüssig umgreift.In one embodiment of the invention, the clamping strip on its side facing the seat shell has a receiving profile which runs parallel to the longitudinal direction of the fastening section and engages in a form-fitting manner around a peripheral section of the fastening strut.
In einer weiteren Ausgestaltung der Erfindung weist die Klemmleiste an ihrer der Sitzschale abgewandten Seite eine Eingriffsnut auf, in die ein Hilfselement zum Einschieben und Verrasten der Klemmleiste in den / dem Befestigungsabschnitt des Aufnahmeprofils eingreifen kann. Auf diese Weise kann die Montage der Klemmleiste vereinfacht oder unterstützt werden. Bei dem Hilfselement handelt es sich zum Beispiel um eine Art Stift oder Bolzen, der zum Beispiel mit einem Hammer beaufschlagt werden kann, um die Klemmleiste in den Befestigungsabschnitt zu treiben.In a further embodiment of the invention, the clamping strip on its side facing away from the seat shell has an engagement groove into which an auxiliary element for inserting and locking the clamping strip can engage in the / the fastening section of the receiving profile. In this way, the assembly of the terminal block can be simplified or supported. The auxiliary element is, for example, a type of pin or bolt that can be acted on with a hammer, for example, in order to drive the terminal strip into the fastening section.
In einer weiteren Ausgestaltung der Erfindung sind mehrere Klemmleisten zum vorzugsweise formschlüssigen Festklemmen der Befestigungsstrebe in mehreren Befestigungsabschnitten des Aufnahmeprofils der Sitzschale vorgesehen. So kann die Stabilität der Befestigung der Befestigungsstrebe an der Sitzschale erhöht werden.In a further embodiment of the invention, a plurality of clamping strips are provided for preferably positively clamping the fastening strut in a plurality of fastening sections of the receiving profile of the seat shell. In this way, the stability of the fastening of the fastening strut to the seat shell can be increased.
Falls das Gestell des Stuhls mehrere Befestigungsstreben aufweist, sind vorzugsweise für jede dieser mehreren Befestigungsstreben wenigstens ein Befestigungsabschnitt im Aufnahmeprofil und wenigstens eine Klemmleiste vorgesehen.If the frame of the chair has several fastening struts, at least one fastening section in the receiving profile and at least one clamping strip are preferably provided for each of these several fastening struts.
In einer weiteren Ausgestaltung der Erfindung weist das Aufnahmeprofil mehrere unterschiedliche Befestigungsabschnitte zum Aufnehmen von Befestigungsstreben von unterschiedlich ausgebildeten Gestellen auf. Das heißt, eine Ausführungsform eines Sitzes bzw. einer Sitzschale kann in Kombination mit verschiedenen Ausführungsformen von Gestellen verwendet werden.In a further embodiment of the invention, the receiving profile has a plurality of different fastening sections for receiving fastening struts from differently designed frames. That is, an embodiment of a seat or a seat shell can be used in combination with various embodiments of frames.
Gegenstand der Erfindung ist auch ein System, das eine Sitzschale und eine oder mehrere Klemmleisten für einen oben beschriebenen Stuhl der Erfindung aufweist.The invention also relates to a system which has a seat shell and one or more clamping strips for a chair of the invention described above.
