Definitions

  • the present patent application relates to an adjustment mechanism in three positions, called “bed”, “couch” and “relax”, of a bed-couch whose cushioning elements are supported by two mutually movable frames made up angles, the first supporting the back frame and the second supporting the seat frame, the angle supporting the back frame being further connected in the form of a hinge joint by two sets of two arms so connected mutually movable to an element of the frame of the sofa bed, a ratchet mechanism which determines two or three of said positions cooperating with a finger.
  • the object of the invention is therefore to present a mechanism in which the profiles forming part of the frame (seat support) and those forming part of the frame (support for the backrest) have a hinge point situated sufficiently low so that the two frames can be fitted with the same mattress part or with two parts joined together.
  • the aforementioned finger which is fixed relative to an angle iron which supports the seat frame and which is shaped so that it comes into contact, in two different places, with a single stop which is provided on the one of said arms movably connected, in this case the arm which is located closest to the aforementioned finger.
  • said finger has on one side a curvature which is profiled so that this curvature comes to strike said single stop during the movement which brings the frame forming the backrest, in an intermediate position, called “relax", between the bed position and the couch position of this frame.
  • said arm has, at its free end, a hollow which bears against said single stop when the frame forming the backrest is brought into its most raised position, that is to say into the " couch".
  • Figure 1 shows the mechanism according to the invention in the position in which the sofa bed is used as a bed.
  • Figure 2 shows the mechanism according to the invention in the position in which the sofa bed is used in the so-called intermediate or "relax" position.
  • Figure 3 shows the mechanism according to the invention in the position in which the sofa bed is used as a sofa.
  • a first part 2 which is fixed to the frame 1 is a fixed part which causes the movably connected arms 5 and 5 'to pivot at 3 and 4.
  • the arm 5 is subjected to the action of a spring 6 which tends to move it in the direction of arrow 7.
  • the angle 11 supports the frame which is part of the seat.
  • Mattresses 12 and 13 which are shown schematically in phantom, equip the frames forming the backrest on the one hand and the seat on the other hand.
  • angles 10 and 11 which form elements of the backrest and of the seat, are interconnected in an articulated manner at 14, each of the angles 10 and 11 having for this purpose a portion in excess thickness designated by the respective references 15 and 16.
  • a ring 14 'forming an intermediate part maintaining a distance is slid on this axis 14 and determines the distance between the planes in which the extra thickness parts 15 and 16 are located.
  • the mechanism according to the invention is of a particularly compact type and the cited drawbacks can be completely eliminated.
  • the compactness of the mechanism is further reinforced by the mounting of the finger 18 and in particular of the part which constitutes this finger as well as the ratchet mechanism which is described below.
  • the finger 18 is constituted by a part which is firmly connected to the angle iron 11 via said axis 14 and by means of a second axis 21 which connects the part of which finger 18 is part to the angle iron 10 which supports the frame forming the backrest.
  • the second axis 21 serves as a stop for each of the notches 22 and 23 of the part 24 which constitutes the main element of the ratchet mechanism.
  • This part 24 is mounted so as to be able to pivot relative to the angle iron 10 at 25 and it is subjected to the action of a return spring in the form of a leaf spring 26.
  • FIG. 2 illustrates the position in which the notch 23 of the part 24 abuts against the second axis 21 while in FIG. 3, it is noted that it is the second notch, in particular the notch 22, which is engaged with the second axis forming a stop.
  • the ratchet mechanism is therefore designed in a very compact manner and fits entirely within the joint between the angles 10 and 11 of the mechanism.
