Definitions

  • the present invention relates to mattresses and, more particularly to mattresses based on vegetable fibers.
  • Mattresses can be covered on one or both sides with a layer of latex.
  • coconut fiber mattresses covered on their upper face with a layer of latex and which, to improve comfort, are composed of several coconut fiber parts of different densities (density of 60 kg / m3 at the head and at the foot, 80 kg / m3) at the back.
  • the parts of different densities are separated and connected by means of transverse layers composed of latex.
  • a disadvantage of these different types of mattresses is that, when they are placed on deformable bed bases comprising for example liftable head and foot ends, there is a risk of breakage of the mattresses because of the low flexibility of these mattresses. vegetable fibers.
  • Another drawback lies in the fact that, when the layer of vegetable fibers is covered with a foam layer, the latter tends to form beads or hollows at the location of the fold lines of the bed base.
  • the object of the invention is to provide a mattress based on plant fibers which can undergo localized deformation along a fold line while keeping the continuity of the surface of the mattress.
  • the subject of the invention is a mattress comprising at least one layer of material based on vegetable fibers produced in at least two blocks, the junction zone of which is approximately in a transverse plane, characterized in that the junction zone between said blocks is arranged along a fold line of the mattress and in that at least in the vicinity of the junction zone, on either side of said transverse plane there is provided a fixed foam layer on each of the two upper and lower faces of the layer based on vegetable fibers.
  • the blocks of material based on vegetable fibers are contiguous or almost contiguous, so that their end portions located on either side of the junction zone are free to move apart from one another by forming a dihedral around an axis corresponding substantially to the fold line, thus avoiding any risk of breaking the plant fibers.
  • a preferred foam for producing the mattresses according to the invention is a natural latex foam and the vegetable fiber is preferably coconut fiber agglomerated with natural latex micro-particles.
  • the density of the foam is substantially the same as that of the layer of material based on vegetable fibers.
  • the mattress comprises at least two blocks 1,2 of material based on vegetable fibers arranged end to end in the longitudinal direction of the mattress.
  • the junction zone located in a transverse plane with respect to this longitudinal direction is designated by the reference 3.
  • Each block comprises at the junction zone a terminal part 4.5 of reduced thickness located in the middle part of each blocks. The latter thus delimit on either side of the junction zone and on the upper and lower faces of the mattress, a recess 6, 7.
  • Each recess is filled with a strip or layer 8, 9 of foam material fixed by example by gluing on said end portions. This bonding is preferably carried out on the horizontal 10 and vertical 11 surfaces delimiting the recesses 6, 7.
  • the width of the recess is advantageously 25 cm.
  • the end portions 4, 5 of the blocks of vegetable fiber material separate from one another to form a dihedral 12.
  • the strips of foam 8, 9 located above and below the junction zone deform and stretch, thanks to the elasticity properties of the latex. It is noted that in this way, in the event of bending of the mattress, the forces are applied mainly tangentially to the bonding surface of the foam layer with the layer of vegetable fibers and do not cause tearing.
  • the mattress comprises a layer of foam material 8 fixed on an entire face of the layer of material based on vegetable fibers. Due to the presence of this foam layer 8, only one recess 7 is necessary. The recess 7 with a width of the order of 25 cm is located on the face based on vegetable fibers not covered with foam and filled with a layer or strip of foam material 9 fixed on the terminal parts 4 and 5.
  • the mattress comprises fixed on each face of the layer based on plant fibers a layer of foam material 8 and 9. Because of this three-layer structure, it is not necessary to provide 'of course.
  • the thickness of the terminal parts 4 and 5 of the blocks 1 and 2 located on either side of the junction zone 3 is not reduced, the thickness of the layer of vegetable fibers being substantially the same over the entire length of the mattress.
  • the thickness of the vegetable fiber blocks prefferably be of the order of one third of the total thickness of the mattress, which makes it possible to produce the mattress according to the invention easily technically and economically by assembly and bonding of blocks of substantially equal thickness.
  • blocks of material based on coconut fibers are assembled, so as to form three superimposed layers, the blocks of material based on coconut of the central layer being offset from the other two blocks of material based on coconut fibers to form a junction as described above at the desired location of the fold line.
  • blocks of material based on coconut fibers are assembled so as to form two superimposed layers and so that the blocks of material based on coconut fibers of the top layer form a junction at the desired location of the fold line.
  • the mattresses according to the present invention can be mattresses for beds, deckchairs, sofas, beds, etc. They can exist in all the sizes usually available and can be covered with the covers traditionally used.
  • the present invention avoids the drawbacks of the prior art in the sense that the mattresses which it offers have neither a break in the layer of plant fibers nor a discontinuity in the surface in the event of bending. They are technically simple to make and their manufacture is inexpensive.
