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. On the legs of the base part is A bracket for the inclusion of a seat plate via swiveling hinged brackets articulated, the back of which is connected to the base part via a linkage supporting the backrest is pivotally connected. The pivot bearing of this boom is close to the vertical Stayer. Between the base part and the carrier, a spring is provided, which is on supports two-part base part. The link plates are specially designed and have two Side walls that are connected to each other via two crossbars. to Connection to the base part is the hinge plate with the crossbar on one of the lower shell of the base part protruding, flat tongue stored after all components in the web-like or tongue-like receptacles provided in the lower shell are stored, the upper shell is put on and connected to the lower one. 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.

  • 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 horizontal axis 4 Handlebar 5 arranged, which in turn connected to the front of a plate-shaped carrier 6 are who has to take the seat plate, which is not shown here. The seat plate can be slidably mounted on this carrier 6. This connection between the handlebar 5 and the carrier 6 is also hinge-like, and the axis 7 of this hinge-like connection lies parallel to the axis 4. The rear side of the carrier 6 is hinge-like around the axis 9 is pivotally connected to the base part 1 by means of a linkage 8, the linkage 8 is also hinged to the base part 1 and the axis 10 of this hinge-like Connection is close to the vertical post 2. That to the rear - to the right in Fig. 1 - protruding Linkage 8 carries the backrest, not shown here.

    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 spring 11 is provided, which is - seen from above - the central section of the base part 1 and one end thereof can be fixed to a bolt forming the pivot axis 7 and the other end thereof is supported on a support bolt, the axis 12 of which lies in the same plane as the axes 4 and 10 of the hinge-like linkages. For reasons of clarity, details are this spring is not shown, which is otherwise designed so that it with respect to their respective active power is adjustable. As a rule, this is a spring combination, consisting of a mechanical coil spring and a central spring Air spring. To adjust the spring force, a lever, not shown here, must be provided.

    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 legs 13 and a web 14 connecting these legs 13. This base part 1 consists of two shells, namely a lower shell 15 and an upper shell 16, the for example, can be made of die-cast aluminum. The parting plane 17 of these two Shells 15 and 16 pass through the web 14 and the two legs 13. Furthermore, the axes are located 4, 10 and 12 in this parting plane.

    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 lower shell 15 in bottom and top views. One in web 14 provided bore 18 with a larger diameter takes the upper end of the vertical Stand up 2. Furthermore, a groove 19 open on both sides is provided in this web 14, which serves to receive a bearing pin which forms the axis 10. On this bearing pin with the axis 10, the linkage 8 is articulated. In addition, 15 are one-sided in this shell open, channel-like depressions 20, 21 and 22 provided in pairs, which are cylindrical and which serve to receive bearing bolts and support bolts. These bearing and support bolts are indicated here by dashed lines. This for Formation of the bearing provided recesses 20, 21 and 22 are in the legs 13 of Shell 15 molded. These paired groove-like depressions 20, 21 and 22 are closed on the sides facing away from each other, so that these recesses have defined depths measured in the plane of the drawing. Bores 23 in this shell 15 are used to hold screws with which the two shells 15 and 16 together be tense.

    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 lower shell 15 on, here too there are recesses 20, 21 with the shell 15 in a congruent position and 22. These recesses form when the shells are screwed together and combined and 16 bearings for receiving the ends of the bearing bolts and support bolts that pass through here dashed lines are symbolized. The free ends of the respective legs 13 are fork-like designed. In the extensions 24 of this fork-like design, the above-described, depressions 20 and 21 arranged in pairs.

    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 Shell 16. the bearing or support bolts inserted into the recesses 20, 21 and 22, the at the free ends of the legs 13 provided bearing bolts with the handlebars 5 be equipped. Through the design and shaping of the wells described here 20, 21 and 22, these bearing and support bolts are clearly and securely positioned. On the shell 16 prepared in this way is now placed on the second shell 15 and subsequently the two shells 15 and 16 are connected by means of screws which extend from the bores 23 be included. The two congruent channels 19 in the web 14 then form a continuous cylindrical bore for receiving a bearing pin on which the Linkage 8 is articulated.

    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 legs 13 between those forming the fork Extensions 24 arranged.

    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 bore 25 visible in FIG. 2 in the base part 1 serves to receive an actuating lever, with which, for example, the spring can be influenced. Because of this closed Construction of the base part dispenses with the arrangement of a large and bulky cover, that prevents the view of the chair mechanism.
