Definitions

  • Box springs comprising a fixed part and, on the side of the head, a lifting movable part, the mattress resting simultaneously on this fixed part and on this mobile part.
  • Belgian patent 511.324 describes a sofa bed comprising a seat connected by connecting rods to a fixed box.
  • the seat consists of a rigid frame carrying a box spring and a mattress.
  • the bed base is in one part and when the inclination of the seat is changed, there is sliding of the mattress on the bed base.
  • Swiss patent 357,517 describes a seat which can be transformed into a rest surface. It includes a seat and two backs, each of which includes a cushion, is connected by links to the seat, and is separated from this seat by a dividing line.
  • the links are arranged so that each file swings around an immaterial axis which extends along the line of separation and coincides with it.
  • the backrest thus pivots around a fixed axis and its raising is not accompanied by a decline in its lower end.
  • the subject of the present invention is a box spring intended to be covered by a mattress, comprising a fixed part and, on the side of the head, a movable lifting part, and arranged to avoid any sliding of the mattress on the bed base during a variation of the inclination of its mobile part.
  • the bed base according to the invention is characterized in that its mobile part is connected to its fixed part by two sets of rods which are each arranged on one side of the bed base, each of these sets being made up of two rods forming a hinged quadrilateral with the fixed and mobile parts so that the lifting movement of the mobile part is accompanied by a decline in its lower end, which prevents the mattress from sliding over the fixed and mobile parts of the backrest.
  • a lockable pneumatic cylinder can be provided connecting the fixed and mobile parts to compensate for the weight of the mobile part and immobilize it in the desired position.
  • an antagonistic spring of short length mounted on the piston rod of the jack and coming into play when the jack is in the vicinity of its fully retracted part corresponding to the horizontal position of the movable part.
  • the bed base has a rectangular fixed frame 1 having in its central part two crosspieces 2a and 2b which are fixed above the side members of the frame, on which a fixed cushion 3 rests, and under which is fixed a substantially median longitudinal tube 5 and arranged in the plane of the frame. It also comprises, on the side of the head, a movable frame 6 on which is fixed a cushion 7 and having two crosspieces 8a and 8b.
  • the mattress 9 rests on the two cushions 3 and 7.
  • the movable frame 6 is connected to the fixed frame 1, on each side, by a first link 10 which is articulated at 11 on the frame 1 and at 12 on the frame 6, and by a second link 13 which is articulated at 14 and 15 respectively on the two frames. These two links constitute with the frames a deformable quadrilateral.
  • the frame 6 can thus be moved from a horizontal position in which it rests on the frame 1, the two cushions 3 and 7 then being in the same plane and practically contiguous, to a raised position shown in FIG. 1. During this movement, not only does the frame 6 pivot, but its lower end moves towards the rear, which prevents the mattress 9 from sliding on the cushions 3 and 7.
  • Elastic means are provided to balance the weight of the frame 6 and that of the cushion 7 as well as the force exerted on this cushion by the upper part of the user's body.
  • These means comprise an elastic cable 16 which is folded in two and the ends of which are hooked to a hoop 17 fixed to the cross-member 8b of the frame 6.
  • the central part of the cable passes over an adjusting element 18 which is movable on a rod 19 secured to the head part of the frame 1 and can be immobilized in the desired position by wedging.
  • a second elastic cable 20 forms a loop which connects a hook 21 secured to the tube 5 and a hook 22 which is fixed to a plate 29.
  • a pneumatic control cylinder 23 is also provided.
  • the cylinder of this cylinder is integral with a trigger 24 which is provided with an operating lever 25 and is pivotally mounted at 26 on the fixed tube 5.
  • the piston rod 27 of the jack is articulated at 28 on the plate 29 fixed to the crosspieces 8a and 8b.
  • a spring 30 is mounted on the rod 27 so as to only come into action when this rod is fully retracted into the cylinder.
  • the operating lever 25 is connected by two cables 31 to a transverse control bar 32 which is articulated at 33 on the longitudinal tube 5 and is provided at one or the other of its ends with a control handle 34.
  • the movable frame 6 located in a given position is locked in this position by the jack 23.
  • the user moves to the seated position and operates the handle 34 so as to pivot the control bar 32 and to actuate the lever 25 of the trigger 24.
  • the jack 23 is thus unlocked and its action as well as that of the elas cable tick 16 ensure the lifting of the frame.
  • the elastic cable 20 opposes this lifting; but it makes it possible, in combination with the jack 23 and the cable 16, to obtain an almost uniform straightening force whatever the position of the frame 6.
