Die Aufgabe der Erfindung besteht darin, ein Bettsofa anzugeben, bei welchem die Umwandlung der Sofafunktion in die Bettfunktion ohne ein Entlangrollen oder Entlangschleifen von Elementen des Bettsofas am Fußboden erfolgen kann.The object of the invention is to provide a sofa bed in which the conversion of the sofa function in the bed function can be done without rolling along or along elements of the sofa bed on the floor.
Diese Aufgabe wird durch ein Bettsofa mit den im Anspruch 1 angegebenen Merkmalen gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind den abhängigen Ansprüchen angegeben.This object is achieved by a sofa bed with the features specified in
Die Vorteile der Erfindung bestehen darin, dass bei einem Bettsofa gemäß der Erfindung beim Herausziehen des Fußteils und des Mittelteils kein Element des Bettsofas auf dem Fußboden bzw. einem darauf liegenden Teppich entlangrollt oder entlangschleift. Folglich tritt bei einer Umwandlung der Sofafunktion in die Bettfunktion keinerlei Beschädigung des Fußbodens bzw. Teppiches auf. Weiterhin gewährleistet der im Anspruch 1 angegebene Verwandlungsbeschlag eine Bodenfreiheit in dem Sinne, dass dieser Beschlag in der Sofafunktion des Bettsofas an seiner niedrigsten Stelle beispielsweise ca. 15 cm über dem Boden angeordnet, deshalb hinter bzw. unter den weiteren Bestandteilen des Bettsofas verborgen und damit von außen nicht sichtbar ist.The advantages of the invention are that in a sofa bed according to the invention when pulling out the foot part and the middle part no element of the sofa bed on the floor or a carpet lying on it rolls or along. Consequently, if the sofa function is converted to the bed function, there is no damage to it Floor or carpet on. Furthermore, specified in
Ein Bettsofa mit den im Anspruch 1 angegebenen Merkmalen wird von der Sofafunktion in die Bettfunktion dadurch umgewandelt, dass das Fußteil nach vorne und gleichzeitig schräg nach oben herausgezogen wird. Bei diesem Herausziehen werden zunächst das Fußteil und das Sitzteil gleichzeitig nach vorne oben bis zu einem Anschlag herausgezogen. Nach dem Erreichen dieses Anschlags erfolgt lediglich noch ein weiteres Herausziehen des Fußteils bis in eine Endposition. Beim Erreichen dieser Endposition hat sich ein Stützbügel, der im vorderen Bereich an der Unterseite des Fußteils vorgesehen ist, aufgeklappt. Mittels dieses Stützbügels kann das Fußteil auf dem Fußboden bzw. dem Teppich abgestellt werden. Während des gesamten Herausziehvorganges hat ein an einem ersten Hebelbeschlag Vorgesehenes Stützelement keinen Kontakt mit dem Fußboden bzw. dem darauf aufgelegten Teppich. Erst in der Endposition ist das Stützelement nach unten verschwenkt, so dass es auf dem Fußboden bzw. dem Teppich aufliegt und eine Bodenstütze bildet.A sofa bed with the features specified in
Bei diesem Stützelement handelt es sich vorzugsweise um eine Rolle. Dies hat den Vorteil, dass bei in die Bettfunktion umgewandeltem Bettsofa auftretenden kleinen Positionsveränderungen des Bettsofas keine Beschädigungen des Fußbodens bzw. Teppichs auftreten.This support element is preferably a roller. This has the advantage that small changes in position of the bed sofa occurring in the bed function converted bed sofa no damage to the floor or carpet occur.
Dieser Effekt wird weiter verbessert, wenn - wie es im Anspruch 3 angegeben ist - die Rollen als Gummirollen ausgeführt sind.This effect is further improved if - as stated in claim 3 - the rollers are designed as rubber rollers.
Der im Anspruch 4 angegebene zweite Hebelbeschlag wirkt auf das Sitzteil ein, hebt dieses beim Herausziehen des Fußteils an und bildet für das Sitzteil den Anschlag beim Herausziehen.The specified in
Ist der zweite Polsterträger mit einem Scharnier verbunden und befindet sich der Drehpunkt dieses Scharniers am Sitzunterrahmen, dann ist gewährleistet, dass das Fußteil auch ohne vorheriges Anheben des Sitzpolsters herausgezogen werden kann.If the second cushion support is connected to a hinge and the pivot point of this hinge is located on the seat subframe, then it is ensured that the foot part can also be pulled out without prior lifting of the seat cushion.
Die Vorteile der Verwendung einer Rolle, wie sie Gegenstand des Anspruchs 7 ist, bestehen darin, dass das Herausziehen des Sitzunterrahmens vereinfacht ist.The advantages of using a roller as claimed in
Die im Anspruch 8 angegebene erste Verbindungsstange dient in vorteilhafter Weise in der Sofafunktion des Bettsofas als Abstützung für das Fußteil und das darüber positionierte Sitzteil, so dass diese Teile nicht in unerwünschter Weise nach unten abklappen können. Des Weiteren begünstigt diese erste Verbindungsstange ein gleichmäßiges Herausziehen des Fußteiles und des Sitzteiles.The specified in
Die im Anspruch 9 angegebene zweite Verbindungsstange begünstigt das weitere Herausziehen des Fußteils, wenn das Sitzteil beim Herausziehen den oben genannten Anschlag erreicht hat.The specified in
Das im Anspruch 10 angegebene Verbindungseisen mit Langloch und das im Anspruch 11 angegebene Führungselement ermöglichen beim Herausziehen des Fußteils ein automatisches Aufklappen des Stützbügels und bei einem Hineinschieben des Fußteils ein automatisches Einklappen des Stützbügels.The specified in

In dieser Bettfunktion des Bettsofas befinden sich die Polsterteile 8, 12 und 15 jeweils in ihrer zweiten Position, wobei das erste Polsterteil als Kopfpolster des Bettes, das zweite Polsterteils als Mittelpolster des Bettes und das dritte Polsterteil 15 als Fußpolster des Bettes dient. Die genannten Polsterteile stoßen fluchtend aneinander, so dass eine ebene Liegefläche vorliegt. Das Kopfpolster kann leicht geneigt sein; so dass der Kopf einer auf der Liegefläche liegenden Person leicht erhöht liegt. Die Höhe der Liegefläche des Bettsofas in seiner Bettfunktion entspricht vorzugsweise der Höhe der Sitzfläche des Bettsofas in seiner Sofafunktion.In this bed function of the sofa bed, the
Bei dem Stützelement 17 handelt es sich vorzugsweise um eine Rolle, insbesondere eine Gummirolle. Dies hat den Vorteil, dass auch dann, wenn in der Bettfunktion des Bettsofas geringfügige Positionsveränderungen des Bettsofas erfolgen, keine Beschädigungen des Fußbodens 6 bzw. eines darauf liegenden Teppichs auftreten.The
Die Verbindungsstangen 22 und 23 bewirken in vorteilhafter Weise ein gleichzeitiges und gleichmäßiges Herausziehen der Polsterteile auf beiden Seiten des Bettsofas. Dies vereinfacht und erleichtert den Herausziehvorgang.The connecting
Die vorliegende Erfindung betrifft nach alledem ein Bettsofa, welches einen bodenfreien Verwandlungsbeschlag aufweist. Dies bedeutet, dass bei der Umwandlung des Bettsofas von der Sofafunktion in die Bettfunktion keine Elemente des Bettsofas auf dem Fußboden bzw. einem darauf liegenden Teppich entlangrollen oder gezogen werden. Dennoch ist aufgrund des oben beschriebenen Verwandlungsbeschlages sichergestellt, dass auch in der Bettfunktion des Bettsofas die notwendigen Abstützungen der Polsterträger und damit der Polsterteile des Bettsöfas gegenüber dem Fußboden vorliegen. Insbesondere wird bei der Umwandlung der Sofafunktion in die Bettfunktion ein in der Sofafunktion keinen Bodenkontakt aufweisendes Stützelement derart verschwenkt, dass es in der Bettfunktion Bodenkontakt hat und folglich als Bodenstütze dienen kann. Dieses Stützelement ist vorzugsweise an einen Hebelbeschlag angelenkt, dessen anderer Endbereich an das Fußteil des Bettes angelenkt ist.The present invention, after all, relates to a sofa bed which has a bottomless transformation fitting. This means that in the conversion of the sofa bed from the sofa function in the bed function, no elements of the sofa bed on the floor or on a carpet lying on it roll or pulled. Nevertheless, it is ensured due to the above-described transformation fitting that even in the bed function of the sofa bed the necessary supports the upholstery and thus the upholstery parts of Bettsöfas be present to the floor. In particular, in the conversion of the sofa function in the bed function in the sofa function no ground contact exhibiting support member is pivoted so that it has in the bed function ground contact and consequently can serve as a floor support. This support element is preferably hinged to a lever fitting whose other end portion is hinged to the foot part of the bed.
