Definitions

  • the present invention relates to a mechanism of articulation of elements forming a bench convertible, more specifically a bench for two positions i.e. seat and bed, such a mechanism is run FR-A-2,553,984.
  • the articulation according to the invention is presented in the form of a removable assembly, which can be interchangeable. It is designed to work assembled in pairs (one on the right side and one on the side left).
  • the articulation makes it possible to assemble all the elements constituting the bench and it constitutes the connection system between the seat and folder, these elements can change position one in relation to each other, and in relation to the base, in allowing the transition from seat to bed, and Conversely.
  • the joint according to the invention works under a synchronized principle, that is to say that we moves from one seat operation from the seat position to the bed position, and vice versa.
  • the joint is more of the non type protruding, that is to say that no constituent body this joint only protrudes in the part reserved for the mattress, on the sleeping surface and on the surface seat, and cannot cause damage to the covering of the entire seat.
  • the articulation is fixed on the back elements and laterally inside these elements to each end, not being visible externally and allowing individual cover seat and back support elements.
  • the operation or operation of the bench done by the user, all at once, facing the furniture by acting on the seat element or on the side of it by action on the element of folder.
  • the existing benches based on the same principle, can only work by performing two maneuvers, that is to say one at the front and the other on the side, to convert the furniture from the sitting position to the lying position and vice versa.
  • the joint according to the invention allows, in the seat position, to access the trunk bedding located inside the base, from the front of the furniture, by lifting the seat element vertically, which stops in this position by allowing the user to have access to the bedding chest on its entire length, without having to hold the element seat.
  • the joint which connects a seat element and a support element backrest each provided with an independent mattress, characterized in that it includes a connecting rod tilting control linked at one end to the element seat, and a connecting rod connecting the other end of said control rod to the element backrest support, so that a pulling movement or thrust applied to the seat element controls a synchronized tilting of the backrest support element horizontally or vertically ensuring obtaining the bed position or the position of seat.
  • the rocker control link at its intermediate part around an axis carried by the base of the cabinet, while its ends are articulated one to a support of the seat element and the other to said connecting rod liaison.
  • the back support element is articulated around an axis carried by a support member fixed to the base, while the seat element is connected to the base by a seat rotation rod which determines with the control rod a parallelogram deformable.
  • a tension spring arranged between the seat element support and connecting rod ensures balance and recall of the support element backrest and seat element.
  • the joint according to the invention allows, during conversions, a easy and effortless handling, whether from the front or side, for benches that may have surfaces sleeping up to two meters long and 1.60 meters wide.
  • a convertible bench equipped on each side with a connecting rods ensuring the passage from the seat position to the bed position and vice versa.
  • the connecting rod located on the side right when we look at the bench, but we will understand that the crankshaft (not shown) which is on the side left is exactly symmetrical with respect to the plane vertical transverse median.
  • the connecting rod assembly comprises a fixing flank 1 laterally secured to the base 2 of the cabinet.
  • a seat rotation rod 4 On the fixing flank 1 is articulated at one end, around an axis 3, a seat rotation rod 4 the other end of which is articulated around an axis 5 to a support 6 to which is fixed a seat element 7.
  • a mattress 8 On the latter is placed a mattress 8, which serves as a suspension in the seat position as in the bed position.
  • a coil spring 20 is hooked to a end to support piece 6 and its other end to the connecting rod 13, to ensure the recall and balancing of the seat element 7 and the backrest element 16 when handling conversion from seat to bed and vice versa.
  • a bar coupling (not shown in the drawing) connects together the control rods 4 placed from the two sides of the bench, ensuring operation symmetrical of the two connecting rods.
  • FIG. 2 represents a position intermediate during movement, and in Figure 3 the final position in bed obtained once the element backrest support 16 has taken a flat position.
  • the spring 20 is tensioned to ensure the recall of the back support element 16 towards the position of seat.
