摘要:
Mechanism for a sofa-bed enabling the adjustment in three positions comprising padding elements supported by two frames; said frames can reciprocally move by means of two angle-bars, concurrent in a point; one of said angle-bars 1 supports the frame forming the seat of the sofa-bed and the second one 2 supports the frame forming the back of the sofa-bed; moreover comprising a kinematism which supports said second angle-bar. The mechanism is characterised in that the angle-bars, without interposition of additional elements, constitute a release mechanism enabling the three positions; having the first angle-bar 1 a shaped profile 4, connected to a pawl 7 at two different points 4' and 4'', and having the second angle-bar a toothed profile 3 enabling a cam 9, fixed to said first angle-bar 1, to engage said toothed profile 3; in this way, the relative position among the two angle-bars is well determined both for "divan" and "relax".

In a reclining structure (1, 21, 41, 61) according to the present invention, support members (2, 22, 42, 62), a seat member (3, 23, 43, 63) and a back member (5, 25, 45, 55, 75) are connected to one another freely with at least two kinds of members out lof these support members, seat member and back member being joined together by a rod (11, 31, 51, 71) of a locking means (13, 33, 53, 73), the rod being disposed so as to cross one of these two kinds of members.. These two kinds of members are locked so as not to be moved with respect to each other with a force imparted only between the rod-crossed member and rod. Accordingly, in order to I re-adjust the reclining structure, a user changes his posture on a chair (1, 21, 61) or a bed (41) so as to release the rod-crossed member and rod from the force imparted therebetween and set the support members, seat member and back member, which constitute the reclining structure, freely movable. After the re-adjustment operation is finished, the user sits or lies on the seat member to cause the rod-crossed member and rod to be locked.

Disclosed is a sofa bed, comprising a mattress frame, a back frame, two arm frames and two cross beams, two arm frames are connected by the two cross beams, wherein the mattress frame and the back frame are rotatably pivoted, the inner side of the arm frame is disposed with a linking mechanism, the linking mechanism comprises a front connecting piece, rear connecting piece and a bridge connecting piece, two ends of the bridge connecting piece are respectively pivoted to the front connecting piece and the rear connecting piece, the bottom end of the front connecting piece is pivoted to the arm frame, the bottom end of the rear connecting piece is pivoted to the arm frame. The linking mechanism comprises a front connecting piece, rear connecting piece and a bridge connecting piece, the components quantity is fewer, the structure is simple, the cost can be reduced at least 10%, also reduced is the weight. The thickness of the linking mechanism is thin, before the sofa bed leaves the factory, the linking mechanism is fixed to the arm frames, not influencing the integral package. When assembling, the top end of the front connecting piece is pivoted to the mattress frame, the top end of the rear connecting piece is pivoted to the back frame, the assembling steps are fewer, making the assembling conveniently. The screw quantity of the sofa bed is efficiently reduced, further reduced is the cost and the weight.
摘要:
Das Polstermöbel (1) weist ein Basiselement (2) und ein insbesondere ein Sitzpolster tragendes Sitzelement (3) auf. Das Basiselement (2) und das Sitzelement (3) sind durch Führungselemente (5, 6) derart verbunden, dass das Sitzelement (3) durch eine kombinierte translatorische und rotatorische Bewegung gegenüber dem Basiselement (2) von einer ersten Position, insbesondere einer Sitzposition, in eine zweite Position, Liegeposition, hin- und herbewegt werden kann. Das Polstermöbel (1) ist derart gestaltet, dass ein wenigstens am hinteren Teil des Sitzelements (3) angeordneter Abschnitt (25) bei der Bewegung von der ersten Position in die zweite Position eine etwa S-förmige Trajektorie durchläuft. Dies führt dazu, dass sich ein an dem Sitzelement (3) angeordnetes Stützelement (17) zur Abstützung des Sitzelements (3), insbesondere eine Stützrolle, zunächst beabstandet dem der Bodenfläche (18) unter dem Basiselement (2) entsprechenden Bodenniveau in Richtung der Vorderseite des Polstermöbels (1) bewegt und sich erst nach dem Überschreiten einer vorgegebenen Wegstrecke auf das Bodenniveau absenkt.
