Definitions

  • the present invention relates to a new type of a bed base of the type constituted by a plurality bars or slats arranged parallel to each other to others transversely to the longitudinal axis of the bedspring.
  • said slats are flexible slats that are attached to each of their ends on a rigid frame thanks to a semi-rigid plastic tip.
  • 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 flexible tips. That said, and despite the end caps, such a box spring has the disadvantage of be flexible and pleasant only in the middle because it presents a certain stiffness when approaching of the frame.
  • US Patent 2,414,978 describes a type of box spring composed of modules linked to each other in a rigid frame, the modules are composed of a slat upper connected to one or more lower slats attached to a central beam which is integral with the frame bed.
  • This box spring remains relatively rigid due to the fact that it does not allow identical vertical deformation at any point of application of the load on the batten.
  • said slat sinks a certain height while the other end which is not subject to the charge remains stationary; it follows that when the sleeper is on the edge of the bed, the bed base is then fully tilted by side.
  • Patent EP 0 463 916 describes a new type of bed base in which the slats are mounted in modules carried by a central beam. This device has for advantage of removing the frame that connects the ends slats which no longer rest on one rigid chassis. But this device does not yet allow to ensure an integral distribution of the deformations across the full width of the bed.
  • box springs slats can consist of several parts articulated such as for example a central part fixed and two ends tilting upwards.
  • the mattress rests on the slats without fixing particular, it follows that when tilting the head the end of the mattress moves by sliding along the slats and this end is outside the frame of the box spring, which means that the elements covering the mattresses (sheets, blankets, etc.) are subject to this sliding and that their placement is affected.
  • too great a tilt of the head brings the slats closer together at the place of the folds to the point where the slats end up overlap. As a result, the head tilt is limited.
  • the object of the present invention is to resolve these different disadvantages that is to say to offer a box spring whose flexibility is distributed over the entire width of the bed wherever the charge and, salt has another embodiment, of propose such a box spring having the advantage of allow head tilt, not limited.
  • the present invention relates to a box spring comprising a plurality of crossbars connected to each of their end to a rigid frame by means of a nozzle comprising a hollow part and preferably two parts hollow intended to receive said bars and comprising, on its underside, two angled supports, characterized in that the lower branches of said bent supports are each end with a gear or wheel portion toothed which engages on the other.
  • Said cogwheels comprising in its center an orifice in which is engaged the end of a rigid rod integral in rotation of the toothed wheel, said rod connecting the end pieces between them and being carried at each of its ends to the frame rigid of the box spring thanks to bearings or rings allowing a rotational movement.
  • Said rigid rods comprise at one of their ends or at each of their ends on the same side of the box spring 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 spiral around the rigid rod and connected to the frame of the bed base by means of an adjustment pad.
  • the rigid frame has a plurality of adjustment pads mounted on a vertical axis one above the other so as to position the end of the spring on a desired height.
  • the rigid rods are preferably of square section or rectangular or crenellated round of a dimension slightly lower than the hole in which they fit.
  • the crossbars are preferably slats in non-flexible material.
  • the tips are preferably made of material semi-rigid with strong elastic memory.
  • box spring can be made up of several articulated parts and preferably in one fixed part and a movable back part mounted in rotation relative to the fixed central part characterized in that said central part comprises a curved ramp and said back part includes a carriage constitutes with two or three rollers intended for roll along the ramp.
  • the ramp is curved in a circular shape concave.
  • rollers are positioned on the carriage preferably with two rollers on one side of the ramp and the third roller on the opposite side of the ramp so that that as you raise or lower the moving part, said ramp slides between the rollers in staying in constant contact with them.
  • the ramp can also be formed in a groove hollow in which the rollers are positioned way to roll inside the ramp.
  • the bed base can also be articulated in a part fixed central unit and two movable end parts.
  • the box spring 1 is composed of cross 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 cross bars 4 are connected to each of their end to a rigid frame 3 through end caps 5.
  • the tip 5 which is preferably of semi-rigid plastic material with strong elastic memory is made up of one or more hollow parts 6 (two in the example shown) intended to receive the cross bars 4 ( Figures 3 and 4).
  • Said nozzle 5 has on its face lower two supports 7 bent outwards.
  • Said angled supports 7 are positioned symmetrically about the central axis of the nozzle 5 and each comprise an upper branch 8 and lower 8 'making an angle ⁇ 90 ° between them.
  • the lower branches 8 end with a portion of toothed wheel 9 with a hole 10 in its center square or rectangular or round section.
  • 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 pad 13 integral with the rigid frame 3, the said spring 12 being spiral mounted around the rigid rod 11.
  • the frame rigid 3 comprises a plurality of studs 13 fixed according to a vertical axis so as to allow the anchoring of the spring 12 at a desired height.
  • the nozzle 5 undergoes a deformation which causes symmetrical movement of the two gears 9. This movement is transmitted by rods 11 to the end piece 5 of the opposite end and therefore simultaneously reproduced at this end, which implies a uniform deformation on the bed base whatever where the load is applied.
  • the spring 12 fixed to one end of the rigid rod 11 allows the bed base 1 to return to its initial position and therefore to have a restoring force upward instant when the load is removed applied to the bed base 1.
  • the springs 12 can be fixed on one end of the rigid rod 11 and on the same side of the box spring since the said rod simultaneously transmits movement to 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 adjusts the force of return of the spring 12 according to the desired mode.
  • the bed base 1 can be made up of several parts: one part fixed central unit and at least one mobile part.
  • the box spring 1 is composed of a part fixed 14 and a movable part 15 which constitutes the backrest and which is rotated relative to the fixed part 14.
  • the whole fixed part 14 and part mobile 15 are connected on the one hand by a curved ramp 16 of concave circular shape, fixed by means of a chassis or other surface on the underside of said fixed part 14 and, on the other hand by a carriage 17 fixedly mounted by means of a chassis or the like 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 on the Figure 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.
  • rollers 18 roll along the ramp 16 while still remaining in contact with said ramp 16.
  • the bending radius of the ramp 16 is preferably equal to the distance between the fixed part 14 and the part mobile 15 so that when lifting said part mobile 15, the mattress which rests on the bed base 1 does not outside the frame of the box spring 1. Furthermore whatever either the position of the movable part 15 the bars or fixed slats that make up the box spring are never contact at the place of the fold and therefore does not never overlap.
  • the bending ramp 16 can be consisting of a hollow groove in which preferably two rollers 18 are positioned in order to roll inside the said ramp when raises or lowers the moving part 15 (Figure 7).
