Description

Sesselmechanik Chair mechanics
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, reference is made to AT 402 602 B and AT 405 124 B in this regard. In the specific embodiment, the components forming the armchair mechanism are predominantly designed as welded steel structures. These steel structures, which are usually not aesthetically pleasing, are often covered by and taken up by a large plastic shell, which is attached to the underside of the seat plate. These spacious plastic shells make the armchair appear heavy and chunky.
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- Die Erfindung löst diese komplexe Aufgabe durch jene Merkmale, die Inhalt und Gegenstand des kennzeichnenden Teiles des Anspruches 1 sind. Zweckmäßige Ausgestaltungen der Erfindung sind in den Unteransprüchen festgehalten.This is where the invention comes in, which aims to construct the armchair mechanics in a way that not only simplifies their construction and assembly compared to conventional constructions, but also that they offer an aesthetically satisfactory sight - the invention solves this complex task by those features that are the content and subject of the characterizing part of claim 1. Expedient embodiments 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:To illustrate the invention, an embodiment will be described in more detail with reference to the drawing, without thereby restricting the invention to this specific embodiment. Show it:
Fig. 1 eine Seitensicht einer Sesselmechanik und Fig. 2 eine Seitensicht des Basisteiles; die Fig. 3 und 4 Untersicht und Draufsicht auf die untere Schale des Basisteiles; die Fig. 5 und 6 die Draufsicht und Untersicht auf die obere Schale des Basisteiles-1 shows a side view of an armchair mechanism and FIG. 2 shows a side view of the base part; Figures 3 and 4 bottom and top view of the lower shell of the base part. 5 and 6, the top and bottom view of the upper shell of the base part
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 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 Trä- ger 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 mounted at the upper end of a vertical post 2 of a conventional type of chair foot, not shown here, and can be rotated about its vertical axis. This base part 1 protrudes laterally from the upright 2, and on the freely projecting front are arranged pivotable about a horizontal axis handlebars 5, which in turn are connected to the front of a plate-shaped carrier 6, which receive the seat plate, which is not shown here Has. The seat plate can be slidably mounted on this support 6. This connection between handlebar 5 and bracket ger 6 is also hinge-like, and the axis 7 of this hinge-like connection is parallel to the axis 4. The rear side of the carrier 6 is hinged about the axis 9 by means of a linkage 8 connected to the base part 1, the linkage 8 on the base part 1st is also hinged and the axis 10 of this hinge-like connection is close to the vertical post 2. The to the rear - in Fig. 1 to the right - projecting 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, which means that the seat and backrest can be adjusted together, but by different angles.
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 - seen from above - lies in the central section of the base part 1 and one end of which can be fixed to a bolt forming the pivot axis 7 and the other end of which can be fixed to one Supports support bolt, the axis 12 is in the same plane as the axes 4 and 10 of the hinge-like linkages. For reasons of clarity, details of this spring are not shown, which, moreover, is designed so that it can be adjusted with regard to its respective active force. As a rule, this is a combination of springs, consisting of a mechanical coil spring and an air spring passing through it in the middle. To adjust the spring force, a lever (not shown here) is to 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, 0 und 12 in dieser Trennebene.FIG. 2 now shows the base part 1 from the side as in FIG. 1, the components described above being removed. This base part has a top or bottom view (FIGS. 3 to 6) of a V-shape 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, which can be made of die-cast aluminum, for example. The parting plane 17 of these two shells 15 and 16 passes through the web 14 and the two legs 13. Furthermore, the axes 4, 0 and 12 lie 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. A bore 18 with a larger diameter provided in the web 14 receives the upper end of the vertical post 2. Furthermore, a groove 19 which is open on both sides is provided in this web 14 and serves to receive a bearing pin which forms the axis 10. The linkage 8 is articulated on this bearing pin with the axis 10. In addition, in this shell 15, one-sided open, channel-like and paired recesses 20, 21 and 22 are provided, which are cylindrical and which serve to receive bearing bolts and support bolts. These bearing and support bolts are indicated here by dashed lines. These recesses 20, 21 and 22 provided to form the bearings are formed in the legs 13 of the shell 15. These paired groove-like depressions 20, 21 and 22 are closed on the sides facing away from each other, so that these depressions have defined depths measured in the plane of the drawing. Bores 23 in this shell 15 serve to receive screws with which the two shells 15 and 16 are clamped together.
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 that is congruent with the lower shell 15; here too, recesses 20, 21 and 22 are found with the shell 15 in a congruent position. These recesses form when the shells 15 are screwed together and combined and 16 bearings for receiving the ends of the bearing bolts and support bolts, which are symbolized here by dashed lines. The free ends of the respective legs 13 are designed like a fork. In the extensions 24 of this fork-like design, the above-described paired depressions 20 and 21 are located.
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, v/obei 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, the bearing or support bolts are inserted into the recesses 20, 21 and 22 in one of the two upwardly open shells, for example the shell 16, v / obei the bearing bolts provided on the free ends of the legs 13 initially with the Handlebars 5 are equipped - By designing and shaping the depressions 20, 21 and 22 described here, these bearing and support bolts are clearly and securely positioned. The second shell 15 is now placed on the thus prepared shell 16 and then the two shells 15 and 16 are connected by means of screws which are received by the bores 23. The two congruent channels 19 in the web 14 then form a continuous cylindrical bore for receiving a bearing pin to 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 the bolts can be seen and for this reason no arrangement must be provided to secure the bolts in position. The links 5 are arranged in the fork-like formations of the free ends of the legs 13 between the extensions 24 forming the fork.
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. Due to this closed construction of the base part, there is no need to arrange a large and bulky cover that prevents the chair mechanics from being seen.
