Description
Die Erfindung bezieht sich auf eine Sesselmechanik zur Verstellung der Sitzfläche und der Rückenlehne mit den Merkmalen des Oberbegriffes des Anspruches 1.The invention relates to a chair mechanism for adjusting the seat and the Backrest with the features of the preamble of claim 1.
Sesselmechaniken vergleichbarer Art sind an sich bekannt. Beispielsweise wird diesbezüglich auf die AT 402 602 B und die AT 405 124 B verwiesen. In der konkreten Ausführungsform sind die die Sesselmechanik bildenden Bauteile überwiegend als geschweißte Stahlkonstruktionen ausgeführt. Diese Stahlkonstruktionen, die in der Regel keinen ästhetischen Anblick bieten, sind häufig von einer großräumigen, aus Kunststoff gefertigten Schale, die an der Unterseite der Sitzplatte festgelegt ist, verdeckt und von ihr aufgenommen. Diese großräumigen Kunststoffschalen lassen den Sessel schwer und klobig erscheinen.Chair mechanics of a comparable type are known per se. For example, in this regard refer to AT 402 602 B and AT 405 124 B. In the specific embodiment the components that make up the chair mechanics are predominantly welded steel structures executed. These steel structures, which usually don't offer an aesthetic sight often from a large, plastic shell that is on the underside of the seat plate is fixed, covered and absorbed by it. These spacious plastic trays make the armchair appear heavy and chunky.
Aus der EP-A-0 839 478 ist eine Sesselmechanik zur Verstellung der Sitzfläche und der Rückenlehne bekannt, die einen von einem vertikalen Steher getragenen und gegenüber diesem auskragenden Basisteil umfasst. Der Basisteil besteht aus zwei Schalen und besitzt annähernd U-Form mit zwei Schenkeln und einem Steg. An den Schenkeln des Basisteils ist über schwenkbare Gelenklaschen ein der Aufnahme einer Sitzplatte dienender Träger angelenkt, dessen Rückseite über ein die Rückenlehne tragendes Gestänge mit dem Basisteil schwenkbar verbunden ist. Das Schwenklager dieses Gestänges liegt nahe dem vertikalen Steher. Zwischen dem Basisteil und dem Träger ist eine Feder vorgesehen, die sich am zweiteiligen Basisteil abstützt. Die Gelenklaschen sind speziell ausgebildet und weisen zwei Seitenwandungen auf, die über zwei Querstege miteinander verbunden sind. Zur Anbindung an den Basisteil wird die Gelenklasche mit dem Quersteg auf einer von der unteren Schale des Basisteils abragenden, flachen Zunge gelagert Nachdem alle Bauteile in den in der unteren Schale dafür vorgesehenen stegartigen bzw. zungenartigen Aufnahmen gelagert sind, wird die obere Schale aufgesetzt und mit der unteren verbunden. Die Montage der Bauteile am Basisteil ist jedoch relativ mühsam, da die mit speziellen Anbindeteilen ausgestatteten Bauteile sehr leicht aus ihren Aufnahmen herausfallen können. Spezielle Anbindeelemente, wie beispielsweise die Gelenklaschen, sind relativ aufwändig und teuer in der Herstellung. Die Lagerung der Querstege in den Seitenwandungen erscheint wenig stabil und verschleissanfällig.From EP-A-0 839 478 is an armchair mechanism for adjusting the seat and the Backrest known, the one carried by a vertical post and opposite this cantilevered base part. The base part consists of two shells and has almost U-shaped with two legs and a web.

The assembly However, the components on the base part are relatively tedious because they have special connecting parts equipped components can easily fall out of their recordings. Specific Tying elements, such as the link plates, are relatively complex and expensive the production. The storage of the crossbars in the side walls appears little stable and prone to wear.
Hier setzt nun die Erfindung ein, die darauf abzielt, die Sesselmechanik in einer Weise konstruktiv so zu gestalten, daß nicht nur ihr Aufbau und ihre Montage gegenüber herkömmlichen Konstruktionen vereinfacht wird, sondern auch, daß sie einen ästhetisch befriedigenden Anblick bietet.This is where the invention comes in, which aims to construct the chair mechanics in a way to be designed so that not only their structure and assembly compared to conventional Constructions are simplified, but also that they are an aesthetically pleasing sight offers.
Die Erfindung löst diese komplexe Aufgabe durch jene Merkmale, die Inhalt und Gegenstand des Anspruches 1 sind.The invention solves this complex problem through those features, content and subject of claim 1 are.
Zweckmäßige Ausgestaltungen der Erfindung sind in den Unteransprüchen festgehalten.Appropriate configurations of the Invention are set out in the subclaims.
Um die Erfindung zu veranschaulichen, wird anhand der Zeichnung ein Ausführungsbeispiel
näher beschrieben, ohne dadurch die Erfindung auf diese konkrete Ausführungsform zu beschränken.
Es zeigen:
Die Sesselmechanik nach Fig. 1 besitzt einen Basisteil 1, der am oberen Ende eines vertikalen
Stehers 2 eines hier nicht gezeigten Sesselfußes herkömmlicher Bauart gelagert und um dessen
vertikale Achse verdrehbar ist. Dieser Basisteil 1 kragt gegenüber dem Steher 2 seitlich
aus, und an der frei auskragenden Vorderseite sind um eine horizontale Achse 4 verschwenkbar
Lenker 5 angeordnet, die ihrerseits mit der Vorderseite eines plattenförmigen Trägers 6 verbunden
sind, der die Sitzplatte, die hier nicht dargestellt ist, aufzunehmen hat. Die Sitzplatte kann
auf diesem Träger 6 verschiebbar gelagert sein. Diese Verbindung zwischen Lenker 5 und Träger
6 ist ebenfalls scharnierartig ausgebildet, und die Achse 7 dieser scharnierartigen Verbindung
liegt parallel zur Achse 4. Die hintere Seite des Trägers 6 ist scharnierartig um die Achse
9 schwenkbar mittels eines Gestänges 8 mit dem Basisteil 1 verbunden, wobei das Gestänge 8
am Basisteil 1 ebenfalls scharnierartig angelenkt ist und die Achse 10 dieser scharnierartigen
Verbindung nahe dem vertikalen Steher 2 liegt. Das nach hinten - in Fig. 1 nach rechts - ausladende
Gestänge 8 trägt die hier nicht dargestellte Rückenlehne.1 has a base part 1, which is at the upper end of a vertical
Stored 2 of a conventional design not shown here and around it
vertical axis is rotatable. This base part 1 laterally protrudes from the upright 2
off, and on the freely projecting front are pivotable about a
Es handelt sich hier bei der vorstehend erörterten Sesselmechanik um eine synchrone Sesselmechanik, das heißt, daß Sitzfläche und Rückenlehne gemeinsam, jedoch um unterschiedliche Winkel verstellbar sind.The chair mechanism discussed above is a synchronous chair mechanism, this means that the seat and backrest are common, but different Angles are adjustable.
Um die Sesselmechanik in einer vorgegebenen Lage zu halten, ist eine Feder 11 vorgesehen,
die im - von oben gesehen - mittleren Abschnitt des Basisteiles 1 liegt und deren eines Ende
an einem die Schwenkachse 7 bildenden Bolzen festgelegt sein kann und deren anderes Ende
sich an einem Stützbolzen abstützt, dessen Achse 12 in der selben Ebene liegt wie die Achsen
4 und 10 der scharnierartigen Anlenkungen. Aus Gründen der Übersichtlichkeit sind Einzelheiten
dieser Feder nicht dargestellt, die im übrigen so ausgebildet ist, daß sie hinsichtlich ihrer
jeweiligen Wirkkraft einstellbar ist. In der Regel handelt es sich hier um eine Federkombination,
bestehend aus einer mechanischen Schraubenfeder und einer diese mittig durchsetzenden
Luftfeder. Zur Einstellung der Federkraft ist ein hier nicht dargestellter Hebel vorzusehen.In order to keep the chair mechanism in a predetermined position, a
Fig. 2 zeigt nun den Basisteil 1 von der Seite wie in Fig. 1, wobei die vorstehend beschriebenen
Bauteile entfernt sind. Dieser Basisteil hat in Drauf- bzw. Untersicht (Fig. 3 bis 6) eine V-Form
mit zwei Schenkeln 13 und einen diese Schenkel 13 verbindenden Steg 14. Dieser Basisteil 1
besteht aus zwei Schalen, nämlich einer unteren Schale 15 und einer oberen Schale 16, die
beispielsweise aus Aluminiumdruckguß gefertigt sein können. Die Trennebene 17 dieser beiden
Schalen 15 und 16 durchsetzt den Steg 14 und die beiden Schenkel 13. Ferner liegen die Achsen
4, 10 und 12 in dieser Trennebene.FIG. 2 now shows the base part 1 from the side as in FIG. 1, the ones described above
Components are removed. This base part has a V-shape when viewed from above or from below (FIGS. 3 to 6)
with two
Die Fig. 3 und 4 zeigen nun die untere Schale 15 in Untersicht und Draufsicht. Eine im Steg 14
vorgesehene Bohrung 18 mit größerem Durchmesser nimmt das obere Ende des vertikalen
Stehers 2 auf. Des weiteren ist in diesem Steg 14 eine beidseitig offene Rinne 19 vorgesehen,
die der Aufnahme eines Lagerbolzens dient, der die Achse 10 bildet. An diesem Lagerbolzen
mit der Achse 10 ist das Gestänge 8 angelenkt. Darüberhinaus sind in dieser Schale 15 einseitig
offene, rinnenartige und paarweise vorgesehene Vertiefungen 20, 21 und 22 vorgesehen,
die zylindrisch ausgebildet sind und die dazu dienen, Lagerbolzen und Stützbolzen aufzunehmen.
Diese Lager- und Stützbolzen sind hier durch strichlierte Linien angedeutet. Diese zur
Bildung der Lager vorgesehenen Vertiefungen 20, 21 und 22 sind in den Schenkeln 13 der
Schale 15 ausgeformt. Diese paarweise vorgesehenen rinnenartigen Vertiefungen 20, 21 und
22 sind auf den einander jeweils abgewandten Seiten verschlossen, so daß diese Vertiefungen
definierte Tiefen aufweisen gemessen in der Zeichenebene. Bohrungen 23 in dieser Schale 15
dienen zur Aufnahme von Schrauben, mit welchen die beiden Schalen 15 und 16 miteinander
verspannt werden.3 and 4 now show the
Die obere Schale 16 (Fig. 5 und 6) weist eine mit der unteren Schale 15 deckungsgleiche Kontur
auf, auch hier finden sich mit der Schale 15 in deckungsgleicher Lage Vertiefungen 20, 21
und 22. Diese Vertiefungen bilden bei miteinander verschraubten und vereinigten Schalen 15
und 16 Lager für die Aufnahme der Enden der Lagerbolzen und Stützbolzen, die hier durch
strichlierte Linien versinnbildlicht sind. Die freien Enden der jeweiligen Schenkel 13 sind gabelartig
gestaltet. In den Fortsätzen 24 dieser gabelartigen Gestaltung liegen die vorstehend beschriebenen,
paarweise angeordneten Vertiefungen 20 und 21.The upper shell 16 (FIGS. 5 and 6) has a contour congruent with the
Bei der Montage werden in eine der beiden nach oben offenen Schalen, beispielsweise der
Schale 16. die Lager- bzw. Stützbolzen in die Vertiefungen 20, 21 und 22 eingelegt, wobei die
an den freien Enden der Schenkel 13 vorgesehenen Lagerbolzen vorerst mit den Lenkern 5
bestückt werden. Durch die Ausgestaltungen und Ausformung der hier beschriebenen Vertiefungen
20, 21 und 22 sind diese Lager- und Stützbolzen eindeutig und sicher positioniert. Auf
die so vorbereitete Schale 16 wird nun die zweite Schale 15 aufgelegt und anschließend werden
die beiden Schalen 15 und 16 mittels Schrauben verbunden, die von den Bohrungen 23
aufgenommen werden. Die beiden deckungsgleich liegenden Rinnen 19 im Steg 14 bilden dann
eine durchlaufende zylindrische Bohrung für die Aufnahme eines Lagerbolzens, an dem das
Gestänge 8 angelenkt wird.During assembly, one of the two upwardly open shells, for example the
Der so gestaltete Basisteil 1 vermittelt dem Beschauer somit einen geschlossenen Eindruck, da
keine stirnseitigen Enden von Bolzen zu sehen sind und aus diesem Grund auch keine Anordnung
vorgesehen werden muß, die Bolzen lagemäßig zu sichern. Die Lenker 5 sind in den gabelartigen
Ausformungen der freien Enden der Schenkel 13 zwischen den die Gabel bildenden
Fortsätzen 24 angeordnet.The base part 1 designed in this way thus gives the viewer a closed impression, since
no front ends of bolts are visible and for this reason no arrangement
must be provided to secure the bolts positionally. The handlebars 5 are in the fork-like
Formations of the free ends of the
Die in Fig. 2 sichtbare Bohrung 25 im Basisteil 1 dient zur Aufnahme eines Betätigungshebels,
mit dem beispielsweise die Feder beeinflußt werden kann. Aufgrund dieser geschlossenen
Bauweise des Basisteils erübrigt sich die Anordnung einer großräumigen und klobigen Abdeckschale,
die den Blick auf die Sesselmechanik verhindert.The
