Definitions

  • the present invention relates generally to a bed base and more particularly a box spring usually called slatted bed base because that it comprises a series of slats arranged parallel to each other and perpendicular to the axis of the bed base, said slats constituting the plane on which the mattress is placed.
  • the slats rest at their ends on a frame rigid by being positioned in elastic end caps allowing movements relative of said ends of slats with respect to the rigid frame when a load is applied to the bed base.
  • the object of the present invention is to eliminate the problem created by the lack resistance to bent levers while keeping the synchronism of the movements of the two ends of the slats and improving the return means elastic.
  • the bed base according to the present invention is a slatted bed base of the type in which the slats are carried at each end by a support, the two supports of the two ends with mechanical means by which movements of the two supports are synchronized so that each slat or each pair of slats moves while remaining parallel to itself, characterized in that said mechanical means consist of at least one gear wheel meshing on a vertical rack, the gear wheels of each end being connected to each other by a hollow rod which makes them integral in rotation, the hollow rod comprising a torsion spring located inside said rod.
  • the slats are represented in pairs, because it is customary in the case of slatted bases to arrange them thus, but the invention is not limited to this particular case, the slats being able to be worn individually by the devices according to the invention.
  • the slats 1 are arranged in pairs and carried each of their ends by a support 10.
  • Each support 10 is constituted by a U-shaped frame 12, each side of which vertical comprises a rack 15, the two racks being symmetrical, facing and facing the inside of the U.
  • the base of the U 12 is horizontal.
  • the U-shaped frame 12 is surmounted by a cross member 13 so as to constitute a closed frame.
  • This cross member 13 has two orifices 11 of rectangular section, each receiving the end of a batten 1.
  • the toothed wheels 16 are carried by the chassis 2.
  • the hollow rod 19 connects one of the toothed wheels 16 of a support 10 to the wheel corresponding tooth 16 of the other support 10.
  • the rod 19 is of square section and engages on a protrusion 17 of one of the wheels 16 which is also of square section, of so that the rod 19 is integral in rotation with this toothed wheel. It is the same with the other end of the rod 19; so that the gear wheels of the two supports 10 are integral in rotation.
  • a rod 3, intended to play the role of a torsion bar, is arranged at inside the rod 19 and fixed to a core 37 (FIG. 3).
  • the core 37 is of section square, so that it cannot rotate inside the rod 19.
  • This rod 3 passes through the toothed wheel 16 secured to the rod 19, passing to inside the tube 26, and protrudes beyond the frame 2, passing through a flange 32 fixed to said frame 2 by screws 31, to lead to a part 33 to which it is rigidly fixed.
  • the flange 32 has a hexagonal orifice 34 and the part 33 is a hexagon nut of corresponding dimensions, provided with a lug 35.
  • All the rods 3 of all the slats 1 therefore constitute the spring of the bed base.
  • the core 37 cannot rotate in the hollow rod 19, but it can slide inside this rod. It is therefore possible, by means of the lug 35, to remove the nut 33 from its housing, rotate it in one direction or another which twists more or less rod 3: we can see that we can adjust the restoring force at will elastic of each rod 3 and therefore adjust at will the tension of the springs of the bed base and that individually. This allows differential adjustment of the elasticity of the bedspring.
  • the invention is not limited to the use of a nut and a hexagonal hole: any other mechanical means allowing the position to be adjusted of the part 33 relative to the flange 32.
  • any other mechanical means allowing the position to be adjusted of the part 33 relative to the flange 32.
  • the U-shaped frame 12 is closed at its upper part by a crosspiece 12a which carries the part 13 by means of a part 14 having a some flexibility, for example a silent block.
  • FIG. 5 represents an assembly which is the reverse of that of FIGS. 1 to 4.
  • the frame 12 is then fixed to the frame 2 of the bed base.
  • the two toothed wheels 16 are carried by the horizontal bar 40a of a inverted T-piece 40 which is fixed at its base to the cross-member 13 carrying the slats 1.
  • the two wheels 16 of two supports 10 which correspond, are made integral in rotation by a hollow rod 19 in which is placed a rod 3 locked in rotation by a core 37 which can slide inside the rod 19.
  • the latter is integral a nut 43 (similar to nut 33) which fits into a hexagonal orifice 44 (similar to orifice 34) made in a plate 42 (similar to flange 32) secured to the T-piece 40.
  • Figures 7 and 8 show a simplified version of the device according to the Figures 1 to 4.
  • This device is similar to that of FIGS. 1 to 4, but only comprises one toothed wheel 116 (instead of two wheels 16) which meshes on a single rack 115, located on one side of an angle 112.
  • a sliding strip 115a made of a material having good friction characteristics, is arranged opposite the rack 115 for maintain the gear 116 in engagement with the rack while guiding it.
  • the hollow rod is of square section because this is easier to make it integral with a wheel 16 or 116 and to block the core 37, but it is obvious that it can be cylindrical, provided you have appropriate blocking means.
