Definitions

  • the invention relates to a spring mattress comprising, in a flexible envelope, an elastic carcass composed of an assembly of springs distributed in transverse assemblies forming successive rows, the springs of each assembly being inscribed in a prism with a substantially base rectangular and these prisms, juxtaposed in the longitudinal direction of the mattress, defining by their free opposite lateral faces the two main surfaces of the mattress, while two adjacent sets of springs are interconnected exclusively at the contiguous edges of the prisms which delimit them, located in said main surfaces.
  • Spring mattresses of this kind are well known and widely used. They have the advantages of being more hygienic on foam or latex mattresses thanks to the large volume of air they contain, of not presenting any risk of allergy for users and of offering excellent shape stability. in time. However, they are relatively rigid and do not lend themselves to use on articulated mattresses, which must receive foam or latex mattresses, these having the flexibility necessary to adapt to the angular configuration that such mattresses can take. .
  • the term "box springs" should be understood here to mean supports of all shapes for mattresses, including slatted frames.
  • the invention aims to remedy this drawback in order to allow the use of spring mattresses on articulated bed bases.
  • At least two adjacent sets among the sets of springs composing the carcass of the mattress are arranged with a certain mutual space and are connected, through the gap thus created, by elastically deformable elements, capable to resume efforts of both extension and compression, which allow the edges facing the prisms delimiting these assemblies to approach or move away from each other, and thus allow a breakage of the main surfaces of the mattress by bending at the right of said interval.
  • these two sets of springs are not in mutual contact and directly connected to each other as is usual, but connected by means of elastically deformable elements which create between these two sets a flexible zone playing the role of a hinge and thus allowing the carcass, and therefore the mattress, to fold along a corresponding transverse break line.
  • This hinge area being arranged opposite an articulation of the articulated bed base called to receive the mattress, the latter can bend and take an angular configuration similar to that given to the bed base.
  • the articulation (s) of an articulated mattress can be in various positions along its length, it is preferable that all the sets of springs are spaced apart and connected in the intervals thus created by elastically deformable elements, as well as has been described above for at least two adjacent sets.
  • the carcass is thus provided with a large number of transverse break lines located between the successive sets of springs.
  • the aforementioned connecting elements comprise first elastically deformable elements arranged between the homologous edges of the sets of springs respectively located in the same main surface of the mattress and, to ensure the horizontal stability of the mattress, second elements elastically deformable disposed at an angle in the thickness of the carcass between the non-contiguous edges of said adjacent assemblies situated respectively in one and in the other of said main surfaces.
  • first elastically deformable elements Only the connections in a given main surface could be provided by first elastically deformable elements, the connections in the other main surface being made by non-deformable articulation elements. But it is preferable, in order to increase the possibilities of angular bending of the mattress, than the contiguous homologous edges of the adjacent sets of springs located in both of the main surfaces are connected by first elastically deformable elements.
  • first elastically deformable elements On the other hand, to improve the stability of the mattress with respect to shearing forces along its longitudinal direction, it should be provided that the attachment edges of the second elements located in the same main surface belong alternately, along of the corresponding interval, one and the other of the two sets connected by these elements, which are thus arranged obliquely sometimes in one direction, sometimes in the other.
  • the connecting elements may be constituted by elastic rods shaped in the form of a flat zigzag, namely preferably in the form of an S flattened for the first elements and, preferably also, in the form of E for the second elements. At least some of the elastic rods constituting the connecting elements can also be wound on themselves in one or more loops in the region of at least one of the angles which they comprise.
  • the connecting elements are grouped into connecting members formed of an elastic rod in one piece which is shaped to reveal two first elements in parallel planes and a second element interposed at an angle between them, the planes of these three elements thus united being arranged so that their section by a perpendicular plane has the shape of a Z.
  • a spring mattress according to the invention comprises an elastic frame or carcass formed of an assembly of springs 1, which is covered by a flexible textile envelope (not shown).
  • the springs 1 are conventional biconical springs, constituted by a winding of elastic metallic wire which ends in two flat and circular turns forming the heads or horns of the spring.
  • the springs 1 are distributed in linear assemblies 2 forming transverse rows which follow one another in the longitudinal direction 3 of the mattress, their pavilions being respectively contained in two parallel planes 4, 5 which define the main surfaces of the mattress.
  • the sets 2 of springs 1 are part of transverse prismatic volumes, of rectangular section, the edges of which are materialized by long wires 6, 7 helically spherical, in the turns of which are taken lateral parts of the pavilions of the springs 1.
  • D other helical wires 8 extend along the longitudinal edges of the mattress and are engaged on parts of the pavilions of the extreme springs of the assemblies 2.
  • the successive sets 2 of springs 1 are not placed side by side, but spaced by intervals 11 equal in width, in which resilient connecting members take place which ensure the assembly of said sets 2.
  • Each of these members 10 is constituted by a elastic wire, preferably metallic (of the "piano string” type), bypassed to reveal (figure 3) three flat elastic elements, namely the first two elements lOa, lOb in the form of flattened S joined by a second element lOc in the form of ⁇ .
  • the planes A, B of the first elements 10a, 10b are parallel and distant by an amount equal to the height of the springs 1, that is to say to the thickness e of the mattress frame (figure 1).
  • the plane C in which the intermediate element 10c is contained is not perpendicular to the planes A, B of the extreme elements lOa, lOb, but extends obliquely with respect to them, so that a section through a plane perpendicular to the three aforementioned planes has the shape of a Z.
  • the extreme branches of the element 10c in the form of ⁇ coincide with the intersections of the plane C with the planes A and B and are merged with the respective extreme branches of the elements lOa, lOb by which the latter are connected to the element 10c.
  • the S-shaped elements lOa and lOb are identical.
  • each elastic element 10a, 10b, 10c can work in its plane both in compression and in extension. Elastic angular deformations can also occur between each of the elements 10a, 10b and the intermediate element 10c.
  • the connecting members 10 are arranged in the intervals 11 separating the sets 2 of springs 1 adjacent.
  • the elements 10a and 10b of these members are taken up by their end branches, terminated by locking tails 13, in the helical attachment wires 6, 7 (FIG. 1), so that these elements are contained respectively in the planes 4 and 5.
  • Several connecting members are used to join two adjacent sets 2, which are distributed over the length of the corresponding interval 11.
  • These members 10 are oriented alternately in one direction and in the other, so that the planes C of their intermediate elements 10c have an obliquity of alternating direction, the section of these planes by a perpendicular plane having the shape of an X , as can be seen in FIGS. 1 and 4.
  • These elements, obliquely connecting the heads of the springs 1 through the thickness e of the carcass ensure, by an effect of crossed triangulation, the stability thereof despite the deformability of the connecting elements 10a, 10b located in the main planes 4, 5.
  • the spring carcass described is capable of leaving its natural plane conformation and of bending, along a transverse break line (FIG. 4), in line with an interval 11 between two adjacent sets 2 of springs, to match the different conformations that can take an articulated base 15 (here a slatted frame).
  • the connecting members 10 introduced between these sets of springs are in fact elastically deformable; along the break line, the elements 10a located in the plane 4 compress and the opposite elements 10b located in the plane 5 expand.
  • the slats 12 are distributed so that there is a slat under each of the rows of springs 1 and of connecting members 10.
  • the slats 12 can be arranged only under the rows of members 10 (FIG. 5) , or only under the rows of springs 1 ( Figure 6).
  • the connecting members 10 have approximately the same extent, in the transverse direction, as the springs 1, and are distributed in this direction at the same pitch as the latter, each member 10 coinciding with a pair of facing springs 1 which it connects together.
  • this is not essential, and it is possible to envisage connecting members dimensioned and distributed differently with respect to the springs 1 of the successive sets 2.
  • the elements 10c of the carcass of a mattress according to the invention, interposed between the two main surfaces, are involved in the degree of flexibility of the mattress, together with the springs 1. It is therefore possible, by playing on the characteristics of these elements which thus constitute auxiliary springs, to modify the comfort properties of the mattress without touching the springs 1.
