Description
Vierbeiniges, mit einer Rückenlehne versehenes Sitzmöbel Die vorliegende Erfindung betrifft ein vierbeiniges, mit einer Rückenlehme versehenes Sitzmöbel, bei wel chem der Sitzrahmen, der Rahmen der Rückenlehne und die beiden Vorderbeine des Sitzmöbels eine starre Einheit bilden.
Gemäss der Erfindung kennzeichnet sich dieses Sitzmöbel dadurch, dass die mittels einer Querstrebe miteinander verbundenen Hinterbeine desselben um eine Querachse schwenkbar angeordnet und in ver schiedenen Schräglagen sickerbar sind. Dadurch ist es möglich, das Sitzmöbel von seiner normalen Sitzstel lung in eine nach hinten geneigte Ausruhstellung zu überführen.
Auf der beiliegenden Zeichnung ist ein Ausfüh rungsbeispiel des Erfindungsgegenstandes veranschau licht.
Fig. 1 und 2 sind zwei senkrechte Schnitte durch das Sitzmöbel in zwei verschiedenen Zustandslagen, und Fig. 3 ist ein in einem grösseren Massstabe ge zeichneter Ausschnitt aus Fig. 1 zur besseren Ver anschaulichung einer Einzelheit.
Das vierbeinige, mit einer Rückenlehne versehene Sitzmöbel gemäss Fig. 1 und 2 hat ein Rahmengestell a, das gleichzeitig den Sitzrahmen; und den Rahmen der Rückenlehne bildet. Am Sitzrahmen sind die bei den Vorderbeine b befestigt, so dass die beiden oben erwähnten Rahmen und die Vorderbeine b zusam men eine starre Einheit bilden. Die beiden Hinter beine c sind mittels einer Querstrebe cl miteinander verbunden und um eine Querachse schwenkbar am Sitzrahmen angeordnet. Hierzu ist für jedes dieser beiden Hinterbeine ein aus zwei Anschlagstücken bestehendes Beschläge vorgesehen.
Das eine, mit d bezeichnete Anschlagstück (siehe Fig.3) ist mittels Schrauben auf der Innenseite des betreffenden Sitz- rahmenschenkels befestigt. Dieses Anschlagstück d weist an seinem Umfang nach innen umgebogene, Zähne bildende Vorsprünge dl und auch in ähnlicher Weise umgebogene Seitenteile d2, die ihrerseits Be grenzungsanschläge bilden. Das andere, mit e bezeich nete Anschlagstück hat. einen U-förmigen Querschnitt und ist mittels Schrauben auf der Aussenseite des obe ren Endteiles des betreffenden hinteren Beines c be festigt.
Dieses Anschlagstück e ist mit einem längsver laufenden Schlitz e1 versehen, durch den hindurch sich ein am andern Anschlagstück d befestigter Bol zen f erstreckt. Zwischen den beiden Anschlagstücken e und d ist demnach eine Schlitz- und Bolzenverbin- dung vorgesehen, die im Bereich des Schlitzes e eine Verschiebung des Anschlagstückes e gegenüber dem Anschlagstück d zulässt. Am Aussenende des An schlagstückes e sind zwei symmetrisch zur Längs mittellinie desselben angeordnete Nocken e2 ausgebil det, zwischen welchen die Zähne dl des Anschlag stückes d eingreifen können.
Ein zwischen diesen beiden Nocken liegender Randteil ist nach innen um gebogen und bildet einen Anschlag g, zwischen wel chem und dem Bolzen f eine Druckfeder<I>h</I> vorgese hen ist, die das Anschlagstück e nach aussen drückt und so den Eingriff zwischen den Nocken e2 und den Zähnen dl sichert.
Um die Hinterbeine c von ihrer in Fig. 1 gezeig ten Stützlage in die Lage gemäss Fig. 2 zu überführen, kippt man das Sitzmöbel etwas nach vorn, fasst dann die Querstrebe cl und zieht die Nocken e2 entgegen der Wirkung der Federn h aus der Verzahnung des Anschlagstückes e heraus.
Die Hinterbeine c lassen sich nun um den Bolzen f herum nach hinten ver- schwenken, wonach durch Nachlassen des auf die Querstrebe cl ausgeübten Druckes der Eingriff der Nocken e2 in die Verzahnung des Anschlagstückes e durch die Druckfedern h herbeigeführt wird.
Four-legged seating furniture provided with a backrest The present invention relates to a four-legged seating furniture provided with a backrest in which the seat frame, the frame of the backrest and the two front legs of the seating furniture form a rigid unit.
According to the invention, this piece of seating furniture is characterized in that the rear legs, which are connected to one another by means of a transverse strut, are arranged pivotably about a transverse axis and can seep in different inclined positions. This makes it possible to transfer the seating furniture from its normal Sitzstel development to a backward sloping resting position.
On the accompanying drawing, an exemplary embodiment of the subject invention is illustrated.
Fig. 1 and 2 are two vertical sections through the seating in two different states, and Fig. 3 is a ge in a larger scale section from Fig. 1 for better illustration of a detail.
The four-legged seating furniture provided with a backrest according to FIGS. 1 and 2 has a frame a, which at the same time is the seat frame; and forms the frame of the backrest. The front legs b are attached to the seat frame, so that the two frames mentioned above and the front legs b together form a rigid unit. The two rear legs c are connected to one another by means of a cross strut cl and are arranged on the seat frame so as to be pivotable about a transverse axis. For this purpose, a fitting consisting of two stop pieces is provided for each of these two rear legs.
The one stop piece marked d (see Fig. 3) is fastened by means of screws on the inside of the relevant seat frame leg. This stop piece d has on its circumference inwardly bent, teeth-forming projections dl and also similarly bent side parts d2, which in turn form limiting stops Be. The other, with e designated stop piece has. a U-shaped cross-section and is fastened by means of screws on the outside of the obe Ren end portion of the relevant rear leg c be.
This stop piece e is provided with a longitudinal slot e1 through which a bolt zen f attached to the other stop piece d extends. Accordingly, a slot and bolt connection is provided between the two stop pieces e and d, which allows the stop piece e to be displaced relative to the stop piece d in the region of the slot e. At the outer end of the stop piece e, two cams e2 arranged symmetrically to the longitudinal center line thereof are ausgebil det, between which the teeth dl of the stop piece d can engage.
An edge part lying between these two cams is bent inwards and forms a stop g, between wel chem and the bolt f a compression spring <I> h </I> is provided, which presses the stop piece e outwards and thus engages between the cams e2 and the teeth dl secures.
In order to transfer the rear legs c from their support position shown in FIG. 1 to the position shown in FIG. 2, the seating furniture is tilted a little forward, then grips the cross strut cl and pulls the cams e2 out of the teeth against the action of the springs h of the stop piece e.
The rear legs c can now be pivoted backwards around the bolt f, after which the engagement of the cams e2 in the teeth of the stop piece e is brought about by the compression springs h by releasing the pressure exerted on the cross strut cl.
