Definitions

  • the present invention relates to a new type of bed base of the type consisting of a plurality of bars or slats arranged parallel to each other transversely to the longitudinal axis of the bed base.
  • said slats are flexible slats which are fixed at each of their ends to a rigid frame by means of a semi-rigid plastic end piece.
  • the flexibility of the box spring is obtained on the one hand by the flexibility of the slats and on the other hand by the flexibility of the end caps. That said, and despite the tips, such a box spring has the drawback of being flexible and pleasant only in the middle because it has a certain stiffness when one approaches the frame.
  • US Patent 2,414,978 describes a type of box spring composed of modules connected to each other in a rigid frame, the modules are composed of an upper slat connected to one or more lower slats fixed to a central beam which is integral with the frame bed.
  • This bed base remains relatively rigid because it does not allow identical vertical deformation at any point of application of the load on the slat.
  • said batten sinks a certain height while the other end which is not subjected to the load remains stationary, it follows that when the sleeper is on the edge of bed, the bed base is then fully tilted to one side.
  • Patent EP 0 463 916 describes a new type of box spring in which the slats are mounted in modules carried by a central beam. This device has the advantage of eliminating the frame which connects the ends of the slats which no longer rest on a rigid frame. However, this device does not yet allow an integral distribution of the deformations transversely over the entire width of the bed.
  • these various slatted bed bases can be made up of several articulated parts such as for example a fixed central part and two ends which can be tilted upwards.
  • the mattress rests on the slats without any particular fixing, it follows that during the tilting of the head the end of the mattress moves by sliding along the slats and this end leaves the frame of the box spring, which causes that the elements covering the mattress (sheets, blankets ...) are subject to this sliding and that their positioning is affected.
  • an excessive inclination of the head causes the slats to come together at the location of the fold so that the slats end up overlapping. As a result, the tilt of the head is limited.
  • the object of the present invention is to solve these various drawbacks, that is to say to propose a box spring whose flexibility is distributed over the entire width of the bed regardless of where the load is located and, according to another mode. embodiment, to propose such a box spring having the advantage of allowing an inclination of the head, not limited.
  • the present invention relates to a bed base comprising a plurality of transverse bars connected at each of their ends to a rigid frame by means of an end piece comprising a hollow part and preferably two hollow parts intended to receive said bars, characterized in that said end piece comprises on its underside two bent supports, the lower branches of said bent supports each ending in a toothed wheel or portion of toothed wheel which engages on the other.
  • Said toothed wheels comprising in their center an orifice in which is engaged the end of a rigid rod integral in rotation with the toothed wheel, said rod connecting the end pieces together and being carried at each of its ends to the rigid frame of the box spring bearings or rings allowing rotational movement.
  • Said rigid rods comprise, at one of their ends or at each of their ends on the same side of the bed base or on both sides of the bed base, an elastic return means, intended to return the rods to their original position.
  • This return means is preferably a spring mounted in a spiral around the rigid rod and connected to the frame of the bed base by means of an adjustment stud.
  • the rigid frame comprises a plurality of adjustment pads mounted along a vertical axis one above the other so as to position the end of the spring at a desired height.
  • the rigid rods are preferably of square or rectangular or round crenellated section with a dimension slightly smaller than the orifice in which they fit.
  • the transverse bars are preferably slats made of non-flexible material.
  • the tips are preferably made of semi-rigid material with a strong elastic memory.
  • the bed base can be made up of several articulated parts and preferably a fixed part and a movable back part mounted in rotation relative to the fixed central part, characterized in that said part central has a curved ramp and said back portion comprises a carriage constitutes with two or three rollers intended to roll along the ramp.
  • the ramp is curved in a concave circular shape.
  • rollers are preferably positioned on the carriage with two rollers on one side of the ramp and the third roller on the opposite side of the ramp so that as the movable part is raised or lowered said ramp slides between the rollers while remaining permanently in contact with them.
  • the ramp can also be formed in a hollow groove in which the rollers are positioned so as to roll inside the ramp.
  • the bed base can also be articulated in a fixed central part and two movable end parts.
  • the bed base 1 is composed of transverse bars 4 which are preferably rigid slats arranged perpendicular to the main axis 2 of the bed base, and regularly spaced along said main axis 2.
  • the transverse bars 4 are connected at each of their ends to a rigid frame 3 by means of end caps 5.
  • the tip 5, which is preferably of semi-rigid plastic material with strong elastic memory is composed of one or more hollow parts 6 (two in the example shown) intended to receive the bars 4 ( Figures 3 and 4).
  • Said nozzle 5 has on its lower face two supports 7 bent outwards. Said bent supports 7 are positioned symmetrically with respect to the central axis of the nozzle 5 and each comprise an upper 8 and lower 8 'branch making an angle ⁇ 90 ° between them.
  • the lower branches 8 end with a portion of toothed wheel 9 pierced in its center with an orifice 10 of square or rectangular or round section.
  • FIG. 3 it can be seen that the end pieces 5 situated at the two ends of the same bar 4 are connected to each other by a rigid rod 11 which is fixed in the orifice 10.
  • Said rigid rod 11 is of square or rectangular or round crenellated section of dimension slightly smaller than the orifice 10 so as to be integral in rotation and is carried at each of its ends to the frame 3 of the bed base (FIG. 4) by means of bearings or rings 19 allowing a rotating movement.
  • a spring 12 is fixed on the one hand to the end of the rigid rod 11 and on the other hand is anchored on an adjustment stud 13 secured to the rigid frame 3, the said spring 12 being mounted in a spiral around the rigid rod 11.
  • the rigid frame 3 comprises a plurality of studs 13 fixed along a vertical axis so as to allow the spring 12 to be anchored at a desired height.
  • the end piece 5 undergoes a deformation which causes a symmetrical movement of the two toothed wheels 9. This movement is transmitted by the rods 11 at the tip 5 of the opposite end and therefore simultaneously reproduced at this end, which implies a uniform deformation on the bed base regardless of where the load is applied.
  • the spring 12 fixed to one of the ends of the rigid rod 11 allows the bed base 1 to return to its initial position and therefore to have an instantaneous upward return force when the load applied to the bed base 1 is removed.
  • the springs 12 can be fixed on a single end of the rigid rod 11 and on the same side of the bed base since the said rod simultaneously transmits the movement at the end opposite and therefore on the opposite side.
  • the plurality of studs 13 fixed one above the other on the frame 3 along a vertical axis makes it possible to adjust the return force of the spring 12 according to the desired mode.
  • the bed base 1 can be made up of several parts: a fixed central part and at least one movable part.
  • the base 1 is composed of a fixed part 14 and a movable part 15 which constitutes the backrest and which is rotatably mounted relative to the fixed part 14.
  • the fixed part 14 and mobile part 15 assembly are connected on the one hand by a curved ramp 16 of concave circular shape, fixed by means of a frame or other surface on the underside of said fixed part 14 and, on the other hand by a carriage 17 mounted fixed by the through a chassis or other surface, on the underside of the movable part 15 so that said carriage 17 comes to move on the ramp 15.
  • Said carriage 17 comprises two rollers and preferably three rollers 18 as illustrated in FIG. 6, that is to say two rollers 18 on one side of the ramp 16 and the third on the opposite side of said ramp 16.
  • the bending radius of the ramp 16 is preferably equal to the distance between the fixed part 14 and the mobile part 15 so that during the lifting of said mobile part 15, the mattress which rests on the bed base 1 does not leave the frame of the bed base 1. Furthermore, whatever the position of the movable part 15, the fixed bars or slats which make up the bed base are never in contact at the place of the fold and therefore never overlap.
  • the bending ramp 16 can consist of a hollow groove in which preferably two rollers 18 are positioned in order to roll inside said ramp when raises or lowers the moving part 15 (Figure 7).
