Definitions

  • the invention relates to a tilting mechanism and a sofa and bed assembly equipped with such a mechanism.
  • the mechanical connection between the sofa and the bed is such that a vertical downward force exerted on the sofa in configuration of use tends to tilt the bed base to the configuration of use of the bed, hence a risk of unexpected bed opening.
  • the invention also provides a mechanism prohibiting unexpected opening of the bed when using the sofa.
  • the invention relates to a mechanism for tilting of a sofa and bed assembly between a first configuration where the sofa is usable while the bed is folded away, and a second position where the bed is can be used while the sofa is folded away.
  • This mechanism includes an articulated deflection arm at a first end, around a fixed axis, and, at a second end, to a structure forming the foot of the sofa.
  • This mechanism also includes a connecting rod connected by a first articulation, to a return lever articulated around a fixed axis and, by a second articulation, to the aforementioned return arm.
  • the axes of articulation of the return lever on the fixed part which supports it, on the one hand, and of the rod, respectively on the return lever and on the return arm, on the other hand, are globally aligned in the first configuration, i.e. in the configuration of use of the sofa.
  • This mechanism therefore includes an articulation of the "to toggle "created between the connecting rod, the return lever and the deflection arm capable of withstanding forces important that can be transmitted to it when an effort intense vertical directed downward is exerted on the seat of the couch.
  • the connecting rod works essentially in compression and can therefore withstand forces important because the knee joint is locked. Therefore, a vertical load on the seat of the sofa does not risk no lead to an unexpected opening of the bed.
  • the tilting movement of the bed allows to control retraction of the sofa but the sofa does not allow to control the tilting of the bed.
  • the invention also relates to a particular use of the aforementioned deflection arm.
  • the deflection arm is articulated, at its second end, to a first part of an armrest, one of which second part is articulated on a seat of the sofa, the axes of articulation of the deflection arm on the foot and on the armrest mentioned above being parallel and distinct.
  • a eccentric joint at the junction area between the deflection arm, the foot and the armrest of the sofa, so that the movement of the armrest can be differentiated foot movement between the two configurations of the mechanism.
  • the invention also relates to a sofa assembly and reads, capable of switching between a first configuration, where the sofa can be used while the bed is folded away, and a second configuration, where the bed is usable while the sofa is folded away, characterized in that it includes a tilting mechanism as above described.
  • a sofa assembly capable of switching between a first configuration, where the sofa can be used while the bed is folded away, and a second configuration, where the bed is usable while the sofa is folded away, characterized in that it includes a tilting mechanism as above described.
  • the sofa and bed assembly comprises a fixed frame 1 formed by two vertical uprights 2 and 2 'connected by an upper cross member 3.
  • a bed base 4 is articulated around an axis X 1 and fixed by compared to amounts 2 and 2 '.
  • the bed base 4 On its external face 4 a visible in FIG. 1, the bed base 4 carries a backrest 5 of a sofa 6 also comprising a seat 7 resting on the floor S by means of two feet 8.
  • the sofa 6 is equipped with two armrests 9 .
  • a bed mattress 10 is disposed against the internal face 4b of box spring 4 and can be used in the configuration of Figures 2 and 7, while the sofa 6 can be used in the configuration of Figures 1, 3 and 4.
  • the bed base 4 is supported by a structure 11 forming a foot, articulated on the external face 4 a of the bed base 4.
  • Plates are secured to the base 4 near the uprights 2 and 2 'and at the axis X 1 .
  • the plate 20 close to the upright 2 is the only one shown in the figures, it being understood that a second plate is provided on the side of the upright 2 '.
  • the plate 20 is articulated around the axis X 1 by means of a shaft 21 intended to be received in a corresponding bearing which is fixed relative to the upright 2. The plate 20 therefore allows tilting between the two aforementioned configurations.
  • a lever 22, of generally triangular shape, is articulated by means of a first axis 23 on the plate 20.
  • This lever 22 is also articulated on a first end 24 a of a connecting rod 24 thanks to a second axis 25.
  • the second end 24b of the connecting rod 24 is articulated on a fixed axis 26.
  • a box 27 is fixed against the internal face of the upright 2, this box extending between this amount and the plate 20.
  • a similar box 27 'visible in FIG. 1, is fixed against the internal face of the upright 2' to protect a second mechanism equivalent to that shown in FIGS. 3 to 7.
  • the box 27 is provided with a bearing 27 a for supporting the axis 26.
  • the lever 22 is articulated by a third axis 28 on one end 29 a of a rod 29 of a gas spring 30 whose body 31 is articulated around a fixed axis 32 supported by the box 27 at level of a second level not shown.
  • the function of the gas spring 30 is to control the tilting of the plate 20, that is to say of the bed base 4, between the two configurations of FIGS. 1 and 2 by compensating for the moments due to the apparent weights of this bed base and of this sofa with respect to the axis X 1 .
  • F 1 the force exerted by the jack 30 on the lever 22.
  • F 2 the force exerted by the connecting rod 24 on the lever 22 and we denote by F 3 the result of the forces F 1 and F 2 which is equal to the force exerted by the lever 22 on the plate 20 at the axis 23.
  • the force F 1 is permanently directed from the rod 29 towards the lever 22.
  • the direction of the force F 2 depends on the position of the plate 20.
  • the connecting rod 24 works in extension in the configuration of FIG. 3A then that it works in compression in the configuration of FIG. 7A, the force F 2 varying between these configurations.
  • the resultant F 3 therefore has a variable value, adapted to the moments exerted on the plate 20 by the apparent weights of the bed base 4 and of the sofa 6, as a function of the angular position of this bed base around the axis X 1 .
  • lever 22 makes it possible to combine the forces F 1 and F 2 generated by the gas spring 30 and by the connecting rod 24, in order to permanently create a resultant F 3 on the plate 20 adapted to these moments, which effectively assists the tilting movement regardless of the open position of the bed.
  • a bell crank arm 40 is articulated at a first end 40 about a shaft 41 fixed relative to the frame 1 and supported by a housing of the bearing 27. At its second end 40b, the arm 40 is articulated by an axis 42 on a frame 43 of the foot 8. This frame is, moreover, articulated by a pin 44 on the seat 7 of the sofa.
  • the armrest 9 is hinged around an axis 46 at the end 40 b of the reference arm 40, the axes 42 and 46 being parallel and separate.
  • the armrest 9 is, moreover, articulated to the seat 7 by means of an axis 47.
  • the eccentric system thus created makes it possible to generate a movement to free up the space needed to pivot the bed thanks to the retraction of the seat 7 of the sofa.
  • the armrest 9 allows the seat 7 to pivot about its axis 44 to reach a position where it is substantially parallel to the foot 8 which is then itself generally at the level of the floor, as shown in figure 7.
  • the sofa then left its place in the bed whose mattress 10 is then horizontal.
  • the armrest 9 works in extension to support the front of seat 7.
  • a return lever 50 is articulated around an axis 51 fixed relative to the frame 1 and supported by a bearing of the box 27.
  • the lever 50 is articulated by means of an axis 52 on a first end 53 a of an angled lever 53 whose second end 53b is articulated around an axis 54 fixed on the plate 20.
  • the pivoting movement of the plate 20 around the axis X 1 induces a pivoting movement of the lever 53 around the axis 54 and, thereby, a pivoting movement of the return lever 50 around the axis 51.
  • the return lever 50 is also articulated by an axis 55 on a first end 56 has a connecting rod 56 whose second end 56 b is articulated by an axis 57 on a yoke 58 secured to the deflection arm 40. Thanks to the articulation of the deflection lever 50 and the connecting rod 56, the pivoting movement of the deflection lever 50 around the axis fixed 51, which is generated by the pivoting of the plate 20, is transmitted to the arm 40, which makes it possible to pass it from the configuration of FIGS. 3 and 4 to that of FIG. 7 passing through the positions of FIGS. 5 and 6.
  • the deflection arm, the deflection lever and the lever thus make it possible to transmit at the foot of the sofa and the elements it supports tilting movements of the plate.
  • the rod 56 is adjustable in length, which allows a adjustment of the relative positions of axes 51, 55 and 57 during mounting the mechanism, in order to obtain the alignment used in the knee joint.
  • the connecting rod 56 can be in one piece and obtained in the form of a foundry piece, its length then being predefined during its design for optimal operation of the system knee pad.
  • the armrest 9 pivots around the axis 46 and tends to press the seat 7 towards the ground S, this movement being obtained by the eccentricity of the movements of the axes 42 and 46.
  • the box 27 is provided with lights 59 and 60 in an arc of circle for the passage of these axes.
  • the invention has been described with a gas spring; she is however applicable with other means of control, and especially with all types of cylinders.
