Description
Die Erfindung betrifft einen Stuhl mit gegen den Sitzschaft federnd neigbarem Sitz und besteht darin, daß eine der beiden zur Abstützung des Sitzes dienenden Platten fest auf dem Sitzschaft gelagert ist und die Neigung der anderen und des mit ihr fest verbundenen Sitzes durch eine Feder beeinflußt wird, die der Aufwärtsbewegung eines im Sitzschaft gelagerten, am Sitz angelenkten Führungsstückes entgegenwirkt.The invention relates to a chair with a seat that is resiliently tiltable against the seat shaft and consists in that one of the two plates serving to support the seat is fixed is mounted on the seat and the inclination of the other and that firmly attached to it Seat is influenced by a spring, the upward movement of an im Counteracts the seat shaft mounted on the seat articulated guide piece.
Zwei Ausführungsbeispiele des Erfindungsgegenstandes sind auf der Zeichnung im
Längsschnitt dargestellt, und zwar zeigt
Abb. ι die erste Ausführungsform mit Innenfeder undTwo embodiments of the subject matter of the invention are shown in the drawing in longitudinal section, namely shows
Fig. Ι the first embodiment with inner spring and
Abb. 2 eine zweite Ausführungsform mit Außenfeder.Fig. 2 shows a second embodiment with an external spring.
Der Sitz 1 ist auf zwei zueinander parallel angeordneten Sitzträgern 2 aufgeschraubt. Mit 3 ist ein Führungsstück bezeichnet, das durch ein Kreuzgelerik mit zwei senkrecht zueinander stehenden Zapfen 4 und 5' mit den Sitzträgern 2 verbunden ist. Mit letzteren ist ferner die Platte 14 fest verbunden. DieThe seat 1 is screwed onto two seat supports 2 arranged parallel to one another. With 3 is a guide piece referred to, which by a Kreuzgelerik with two perpendicular to each other standing pins 4 and 5 'is connected to the seat supports 2. With the latter is also the plate 14 is firmly connected. the
»5 Platte 14 stützt sich auf eine Platte 6, die mit dem Schaft 5 fest verbunden ist. Der Schaft 5 und die Platte 6 sind fest im Gestell des Stuhles, das strichpunktiert angedeutet ist, gelagert. Das Führungsstück 3 ist innerhalb des Schaftes gleitbar und besitzt eine mit Gewinde versehene Bohrung 15, in welche die Stellstange 16 eingeschraubt ist. Um ein Verdrehen des Teiles 3 im Sitzschaft 5 zu verhindern, ist im Teil 3 eine Nut 17, να. welche ein im Sitzschaft 5 fester Stift 18 hineinragt. Ferner ist ein Ring 19 durch eine Stellschraube 20 in der Hülse befestigt und bildet ein Widerlager für das eine Ende der die Stellstange 16 umgebenden Feder 9, deren anderes Ende gegen einen im Sitzschaft 5 geführten Ring 21 auf ruht, der gegen einen verdickten Teil 22 der Stellstange 16 anliegt. Im unteren Ende des Sitzschaftes 5 ist eine Hülse 23 geführt und dient zur Führung der Stellstange 16. Ein Handrädchen 24 ist auf dem mit Gewinde versehenen Ende der Stange 16 verstellbar. Außerdem ist auf dem unteren Ende der Stange 16 eine Flügelmutter 8 befestigt, welche zur Verstellung der Federspannung dient, indem durch sie die Stange 16 mehr oder weniger in das Führungsstück 3 eingeschraubt werden kann.»5 Plate 14 is supported on a plate 6 which is firmly connected to the shaft 5. The shaft 5 and the plate 6 are fixedly mounted in the frame of the chair, which is indicated by dash-dotted lines. The guide piece 3 is slidable within the shaft and has a threaded bore 15 into which the control rod 16 is screwed. In order to prevent the part 3 from rotating in the seat shaft 5, there is a groove 17, να in part 3. which a pin 18 fixed in the seat shaft 5 protrudes. Furthermore, a ring 19 is fastened by an adjusting screw 20 in the sleeve and forms an abutment for one end of the spring 9 surrounding the adjusting rod 16, the other end of which rests against a ring 21 guided in the seat shaft 5, which rests against a thickened part 22 of the Control rod 16 is applied. A sleeve 23 is guided in the lower end of the seat shaft 5 and serves to guide the adjusting rod 16. A handwheel 24 is adjustable on the end of the rod 16 provided with a thread. In addition, a wing nut 8 is attached to the lower end of the rod 16 and is used to adjust the spring tension by allowing the rod 16 to be more or less screwed into the guide piece 3.
Wenn der Sitz 1 unter dem Einfluß des Körpergewichtes nach irgendeiner Seite geneigt wird, so kippt die Platte 14 auf der Platte 6, und das Führungsstück 3 mit Stange 16 bewegt sich unter Anspannung der Druckfeder 9 nach oben. Durch Einstellen des Handrädchens 24 kann der Hub der Teile 3, 16 beim Neigen des Sitzes, der durch den Abstand des Handrädchens 24 von der Unterkante des Schaftes 5 gegeben ist, nach Belieben gewählt werden. Diese Ausführung bringt den Vorteil, daß 'die Feder 9 und die sich bewegenden Teile staubsicher innerhalb des Schaftes 5 untergebracht sind.When the seat 1 is inclined to either side under the influence of the body weight is, the plate 14 tilts on the plate 6, and the guide piece 3 with rod 16 moves under tension of the compression spring 9 upwards. By setting the Handwheel 24, the stroke of the parts 3, 16 when tilting the seat, which is by the Distance of the handwheel 24 from the lower edge of the shaft 5 is given, at will to get voted. This embodiment has the advantage that 'the spring 9 and the moving parts are housed dust-proof within the shaft 5.
Die Ausführungsform nach Abb. 2 unterscheidet sich von der vorbeschriebenen da-The embodiment according to Fig. 2 differs from the one described above.
durch, daß bei ihr eine Außenfeder 9' angeordnet ist. Zu diesem Zweck ist das untere Ende des Schaftes 5 mit Gewinde versehen, und auf ihm ist eine Scheibe 19' aufgeschraubt, gegen welche das eine Ende der Feder 9 aufruht. Das andere Ende der letzteren stützt sich auf das Handrädqhen 8', das auf das untere, mit Gewinde versehene Ende der Stange 16 aufgeschraubt ist. Durch Verstellen des Handrädchens 8' kann die Vorspannung der Feder 9' verändert werden. Die Hubbegrenzung ergibt sich aus dem einstellbaren Abstand zwischen dem unteren Ende des Schaftes 5 und einer auf dem Handrädchen 8' aufruhenden Hülse 23'. Die Wirkungsweise dieser Ausführungsform ist die gleiche wie diejenige nach Abb. 1.by that an outer spring 9 'is arranged in her. For this purpose is the lower one The end of the shaft 5 is threaded and a washer 19 'is screwed onto it, against which one end of the spring 9 rests. The other end of the latter rests on the handwheel 8 ', the is screwed onto the lower, threaded end of the rod 16. By adjusting of the handwheel 8 ', the bias of the spring 9' can be changed. The stroke limitation results from the adjustable Distance between the lower end of the shaft 5 and one on the handwheel 8 'resting sleeve 23'. The mode of operation of this embodiment is as follows same as the one in Fig. 1.
Während beim Stuhl nach Abb. 1 die Durchtrittsöffnung des Schaftes in der Symmetrie-While with the chair according to Fig. 1 the passage opening of the shaft in the symmetry
ao achse der Platten 6 und 14 liegt, so daß der Neigung des Sitzes nach verschiedenen Richtungen ein gleich großer Widerstand entgegengesetzt wird, so sind nach der Ausführungsform nach Abb. 2 Platten 14 und 6 gewählt, welche unsymmetrische Form in bezug auf den Durchtrittspunkt des Schaftes haben. In diesem Falle ist der Widerstand, der dem Neigen des Sitzes in verschiedenen Richtungen entgegensteht, je nach dem Abstand des Kippunktes von der Schaftachse verschieden.ao axis of the plates 6 and 14 is so that the Inclination of the seat in different directions an equal resistance opposite will, so are according to the embodiment according to Fig. 2 plates 14 and 6 selected, which asymmetrical shape in relation have on the point of passage of the shaft. In this case the resistance is which prevents the seat from tilting in different directions, depending on the distance of the tipping point different from the shaft axis.
An Stelle des Kreuzgelenkes 4, 5 könnte das Führungsstück 3 mit einer einfachen Verdickung versehen sein, gegen welche die Platte 14 in der geneigten Lage zwecks Begrenzung der Neigung sperrt. Es ist sogar ein Weglassen der Feder denkbar, da der Sitz durch das Gewicht der auf dem Stuhl ruhenden Person selbsttätig wieder von der geneigten Lage in seine Ausgangslage zurückgebracht wird.Instead of the universal joint 4, 5, the guide piece 3 could have a simple thickening be provided against which the plate 14 in the inclined position for the purpose of limitation the slope locks. It is even conceivable to omit the spring, since the seat is made by the weight of the chair resting person is automatically brought back from the inclined position to its starting position will.
