Definitions

  • the present invention regards a mechanism for sofa-beds enabling the adjustment in three positions, said "bed”, “divan” and “relax", of a sofa-bed.
  • Such mechanisms are generally release mechanisms comprising two reciprocally moving angle-bars, a kinematism, similar to an articulated quadrilater, many intermediate elements forming a seat and a ratchet to lock the sofa-bed in the positions termed "divan” and "relax", and, at least, two toothed profiles that, engaging each other, determine the reciprocal position of the angle-bars and, also, the position of the frames supporting the sofa-bed.
  • the invention is different from the standards on the market thanks to the fact that the angle-bars constitute a release mechanism without the interposition of additional elements; wherein the first angle-bar has a shaped profile and is adapted to engage a pawl at two different points said pawl is positioned upon a back lever of an articulated quadrilateral arrangement and has variable relative motion with respect to said shaped profile; the second angle-bar has a toothed profile enabling a cam, fixed to said first angle-bar, to engage said toothed profile; in this way, the relative position between the two angle-bars is well determined to enable said three adjustment positions to be achieved.
  • the other aim of the invention is a remarkable reduction of the number of the hinges, number that, as it will be seen in the detailed description, is not higher than five.
  • the cam and the toothed profile of the second angle-bar are mutually stressed by means of compression, avoiding therefore any tangential stress for the teeth of the profiles.
  • the present sofa-bed is made of padding elements supported by two frames; said frames are connected so that they can reciprocally move by means of two angle-bars, concurrent in a point; one of said angle-bars 1 supports the frame which makes up the seat of the sofa-bed and the second one 2 supports the frame forming the back of the sofa-bed.
  • the angle-bar 2 is part of an articulated quadrilateral comprising a fixed lever 11 (which has two fixed hinges 11' and 11" at its ends), two movable levers, a front one 5 and a back one 6.
  • An elastic return element 8 connects the fixed lever 11 to the movable back lever 6.
  • the two levers 5 and 6 are connected to the second angle-bar by means of the hinges 12 and 6' respectively.
  • the angle-bars 1 and 2 and the front lever 5, meet at said hinge 12.
  • the angle-bars without interposition of additional elements, form a release mechanism enabling the desired positions; in fact, the first angle-bar 1 has a shaped profile 4, such to engage, at two different points 4' and 4", a pawl 7; said pawl is positioned on the back lever 6 of the articulated quadrilateral, and has variable relative motion with the respect to said shaped profile when in the positions "divan” and "relax"; moreover, the other angle-bar 2 has a toothed profile 3 enabling a cam 9 (fixed to said first angle-bar by means of the hinge 9" and submitted to the action of a return spring 10) to engage said toothed profile; in this way, the relative position among the two angle-bars is well determined to enable said three adjustment positions to be achieved.
  • cam 9 is on the same plane of the angle-bar 2 and, in particular, of its toothed profile 3. According to a preferential realisation, it is also possible to further ensure the complanarity between the cam and the angle-bar by means of a fixing plate 13.
  • the principle of functioning of the mechanism is very simple.
  • the shaped profile 4 of the first angle-bar 1 presents a hollow 4" receiving the pawl 7 in the said position "divan” and a projecting portion 4' able to stop the pawl 7 in the said position "relax".
  • the projecting portion 4' presents a flat surface, without hollow, and, therefore, the said position "relax” is determined by the contact at just one point between said projecting portion 4' and the pawl 7.
  • the positions "divan” and “relax” are obtained when the surface 9' of the cam 9 engages the toothed profile 3 of the second angle-bar 2; this fact, in a univocal way, determines the reciprocal position of the two angle-bars.
  • the way of working of the surface 9' of the cam and of the teeth of the toothed profile 3 is proper because they are both stressed by compression and not tangentially.
  • the mechanism in object is extremely simple, capable of performing, in an effective way, functions which, up to now, were performed only by very complex mechanisms with a large number of components.
  • the invention is remarkably different from the others, known as prior art, because it needs only five hinges, that is: the two fixed hinges 11' and 11" of the articulated quadrilateral, the hinge 6' which connects the back lever 5 of the quadrilateral 6 with the second angle-bar 2, the hinge 12 at which the two angle-bars 1 and 2 and the front lever 5 of the articulated quadrilateral meet and the hinge 9" which connects the first angle-bar 1 with the cam 9.

  1. Es handelt sich um einen Mechanismus für Bettsofas, der eine Einstellung in drei unterschiedliche Positionen ermöglicht. Die Sofapolsterung wird teilweise von zwei miteinander verbundenen Rahmen gehalten, so dass diese sich wechselseitig auf zwei Winkeleisen, die an einem Punkt zusammentreffen, verschieben lassen. Ein Scharnier (1) hält den Rahmen, der die Sitzfläche bildet und ein zweites Scharnier (2) hält den Rahmen der Rückenlehne und enthält auch ein vierseitiges Getriebe, das das og. zweite Winkeleisen bewegt. Hierbei ist wichtig, dass die beiden Winkeleisen, ohne Zwischenstellung zusätzlicher Elemente, einen Schnappmechanismus bilden, der von den og. drei Positionen mindestens zwei zu erreichen ermöglicht. Dies erfolgt mittels des Profils (4) des ersten Winkeleisens (1), das so geformt ist, dass es an zwei verschiedenen Punkten (4', 4") mit einem Sperrzapfen (7) in Kontakt kommt. Dieser Zapfen befindet sich auf dem Hebel (6) einer vierseitigen Gelenkvorrichtung und hat einen relativ variablen Bewegungsspielraum hinsichtlich des og. Profils (4), während das zweite Winkeleisen (2) mit seinem Zahnprofil (3) einem am ersten Winkeleisen (1) befestigten Nocken (9) eine Verbindung zu demselben Zahnprofil (3) ermöglicht, so dass die Position zwischen den beiden Winkeleisen so festgestellt wird, dass die Regelung in 3 Positionen möglich ist.
  2. Mechanismus wie unter 1), dadurch charakterisiert, dass das dem ersten Winkeleisen (1) angepasste Profil (4) sowohl eine Einkerbung aufweist (4"), so dass der Sperrzapfen (7) in der "Divano" genannten Position einrastet, als auch einen kleinen Vorsprung (4'), so dass der Sperrzapfen (7) in der "Relax" genannten Position blockiert wird.
  3. Mechanismus wie unter 2), dadurch charakterisiert , dass der kleine Vorsprung (4') eine ebene Oberfläche hat, ohne Einkerbungen, so dass die "Relax" genannte Position durch einen einzigen Kontakt zwischen demselben Vorsprung (4') und dem Sperrzapfen (7) bestimmt wird.
  4. Mechanismus wie unter 1), dadurch charakterisiert , dass der Nocken (9) eine Oberfläche aufweist (9'), die abwechselnd in Kontakt tritt mit dem Zahnradprofil (3) und dem zweiten Winkeleisen (2), so dass die wechselseitige Position der beiden Winkeleisen einseitig festgelegt wird.
  5. Mechanismus wie unter 1)- 4), dadurch charakterisiert , dass die Vorsprünge (9') des Nockens (9) und des Zahnprofils (3) des zweiten Winkeleisens (2) untereinander gegenseitig durch Kompressionsdruck belastet werden.
  6. Mechanismus wie unter 1), dadurch charakterisiert, dass der Nocken (9) komplanar zum zweiten Winkeleisen (2) mit Zahnprofil (3) ist.
  7. Mechanismus wie unter 6), dadurch charakterisiert, dass die Komplanation zwischen dem Nocken (9) und dem Winkeleisen (2) noch durch eine zusätzliche Abstützplatte (13) abgesichert wird.
  8. Mechanismus wie unter 1), 4), 5), 6) und 7), dadurch charakterisiert, dass der Nocken (9) einem elastischen Kontrollelement (10) untersteht.
  9. Mechanismus wie unter 1), dadurch charakterisiert, dass in dem Vereinigungspunkt (12) zwischen den beiden Winkeleisen (1) (2) auch der Vorderhebel (5) der vierseitigen Gelenkvorrichtung konvergiert.
  10. Mechanismus wie unter 1), dadurch charakterisiert, dass er nur 5 Gelenke benötigt, und zwar im Einzelnen die beiden festen Scharniere (11' und 11") der vierseitigen Gelenkvorrichtung, das Scharnier (6'), das den hinteren Arm der vierseitigen Gelenkvorrichtung (6) mit dem zweiten Winkeleisen (2) bewegt, das Scharnier (12), in dem die beiden Winkeleisen (1) (2) und der Vorderhebel (5) der vierseitigen Gelenkvorrichtung konvergieren und das Scharnier (9"), das das erste Winkeleisen (1) mit dem Nocken (9) verbindet.
