Definitions

  • the present invention relates to a mattress support.
  • the invention is conceived for a mattress support based on renewable composite materials.
  • mattress support must be interpreted in the broadest sense of the word and also comprises any type of support structure or frame conceived for supporting a user with certain comfort, and it therefore relates, in addition to a mattress support, to other types of furniture as well for sitting or lying down, lawn furniture, beach chairs, recliners, orthopedic apparatuses, etc.
  • Mattress supports called slatted mattress supports or Lattoflex are already known; these supports are made up of several parallel slats, oriented in the transverse direction and supported laterally on flexible rubber support points.
  • Mattress supports which are made up of a large amount of flexible frame elements or projections (Lattoflex 200-300) which are each assembled individually on support arms serving as torsion springs, are also known.
  • Document BE 1012356A3 of the company LS Bedding, of Belgium also discloses a device for assembling in an elastic and height-adjustable manner with respect to the edge of the bed, the bending slats of a slatted mattress support, made up of a curved flexible arm which must be fixed inside the structure of the bed, in which every time the end of at least one slat of the slatted mattress support fits, and a height-adjustable casing which is fixed on the structure of the bed to support the previously mentioned flexible arm, which when being used mainly extends horizontally and has an upper end and a lower end, of which the upper end extends enough above to support one or more slats at the height of the structure of the bed and in which the upper and lower ends of the curved flexible arm previously mentioned are interconnected by an elastic intermediate part.
  • document EP 1 127 520 B1 of the company Oniris SA of France describes a mattress for a solar bed in which transversely arranged slats of wood parallel with respect to one another are glued in a flexible material, which serves as an articulating element between the slats.
  • the assembly must have a series of steel springs and a protective layer of foam to make it a usable assembly.
  • the separating elements in fact consist of the elements that are generally known and used for slatted mattress supports and are installed in the grid element in an extractable and flexible manner.
  • This structure is arranged on a rigid board in which there are three separate bags filled with viscoelastic foam.
  • Document EP 1 281 339 A1 of the Compagnie desêt Epeda et Merinos of France describes a frame for a bed made up of flexible slats oriented parallel in the longitudinal direction which allow lifting of the frame from a horizontal lying down position to a more vertical sitting position.
  • Document EP 1063081 discloses a method of making a mattress support which is made up of at least one textile fabric as a flexible material and ofmissionments.
  • the aim of the present invention is to offer a solution for at least one of the previously mentioned drawbacks and others, given that it offers a method and a device which allow making a mattress support which is made up of at least one textile fabric as a flexible material and of reinforcements, in which the reinforcements are formed by arranging the textile fabric in several layers one on top of the other and then hardening them locally with a hardening substance and alternating these pieces with pieces of non-reinforced textile fabric.
  • One advantage is that the construction of a mattress support is thus substantially simplified.
  • the invention allows the manufacturing of the flexible material support, in the form of textile fabric, and the reinforced pieces, arranged, for example, in the form of a strip, from one single part and from one common material, which will then be locally reinforced with a second material.
  • Another advantage is that the entire design of a mattress support can be done by using biological and/or recyclable and/or renewable materials.
  • the mattress support is completely biodegradable and recyclable.
  • Another advantage of the invention is that an elastic assembly can be formed in the manner previously mentioned which can be used as a mattress support of a desired shape and at the same time meets the user's comfort requirements.
  • the mattress support can be made in a very simple manner and, where appropriate, even in a continuous process, with maximum savings in energy, emissions, production time, manual labor and raw materials.
  • Another advantage is that the method allows using the most common and classical production techniques for preparing the raw materials and assembling the mattress support according to the invention.
  • Another further advantage is that the reinforcements can be arranged in the most indicated places, in the most optimal shape and in a simple manner, to realize the best force distribution and reinforcements, but also at the same time to be able to achieve maximum sitting or lying comfort for the user.
  • a textile fabric is used as a flexible material which is completely or partially made up of natural fibers, such as linen, sisal, cotton, hemp, coconut, jute, balsa, for example, or the like, where appropriate, combined with synthetic fibers such as for example poly(ethylene terephthalate) (PET) or polypropylene or derivatives or mixtures thereof.
  • natural fibers such as linen, sisal, cotton, hemp, coconut, jute, balsa, for example, or the like, where appropriate, combined with synthetic fibers such as for example poly(ethylene terephthalate) (PET) or polypropylene or derivatives or mixtures thereof.
  • PET poly(ethylene terephthalate)
  • polypropylene polypropylene
  • the reinforcements are applied on or in it by arranging the textile fabric in several layers one on top of the other, then impregnating them locally and in strips with a hardening substance and then hardening the material.
  • thermoplastic material is used as a hardening material, which is obtained, where appropriate, from of a recyclable and/or renewable source and is CO 2 neutral, particularly from a biomaterial, such as for example a polylactide or derivatives or mixtures thereof.
  • a heat-setting resin is used as a hardening material, which is obtained, for example, from a recyclable and/or renewable source and is CO 2 neutral, particularly from a biomaterial, such as for example furfuryl alcohol or derivatives and mixtures thereof.
  • a typical two-component resin is used as a hardening substance, which resin can be, for example, based on polyester, epoxy, polyurethane, ureaformaldehyde, melamine, polyimide, etc.
  • the reinforcements are previously made as individual mechanical components which are then introduced in or on the flexible material.
  • These components are, where appropriate, made up of several layers of textile fabric which have previously been arranged one on top of the other, molded in the desired shape, impregnated with hardening material and hardened.
  • the hardening takes place by areas and the hardened areas are interconnected to one another by non-hardened flexible textile fabric.
  • the hardened areas are arranged according to straight lines crosswise along the length of the mattress support inside or on the flexible material.
  • the hardened areas are arranged according to a mechanically, dynamically and/or aesthetically optimized pattern.
  • the reinforcements are given a smooth and glossy surface structure; in another embodiment, however, they are given a rough and dull surface structure.
  • the local reinforcements are previously given a slightly curved and convex shape.
  • the elastic structure which, according to the invention, is obtained as previously mentioned, is used directly as a mattress support by installing it on a lower elastic structure.
  • the elastic layer made up, for example, of polyether, polyurethane foam or of metal coil springs is arranged on a self-supporting structure made of wood or aluminum, for example.
  • linen is used as a flexible material.
  • biocomposite material When it is used in combination with bioresins, as is the case in a preferred embodiment of the invention, a biocomposite material will be formed which has the following advantages, among others:
  • a bioresin such as a polylactide or polymerized furfuryl alcohol for forming reinforcements, as is done in a preferred embodiment of the invention, are, among others, that these resins are made from a biomass containing lignin, cellulose or hemicellulose, and because of that it can originate from, for example, residues of the sugar or agricultural industry.
  • bioresins are made from CO 2 neutral and renewable raw materials, and they can be completely recycled.
  • the linen is supplied as a woven textile.
  • the band of linen is locally saturated with a hardening substance, for example with furfuryl alcohol, and the assembly will then be hardened by exposing it, for example, to an increased temperature.
  • a hardening substance for example with furfuryl alcohol
  • preimpregnated and partially polymerized insertions pre-pregs
  • fiber spraying resin injection, reactive injection, wet pressing, sheet or bulk compound moulding, pultrusion, wrapping, steamer treatment, vacuum moulding, etc.
  • Figure 1 schematically shows a perspective view of the embodiment of a mattress support 1 according to the invention in which a textile fabric 2, in this case in the form of a linen fabric, is introduced in a die or mould 3 having the desired profile, in this case in the form of parallel cross members 4 which are oriented at a regular distance from one another in the longitudinal direction 5.
  • the flexible material 2 here in the form of a linen fabric, is folded in the established manner by the profile of the cross members 4, and then it is locally impregnated with a hardening resin.
  • the flexible material 2 is removed from the mould or die 3 on which, where appropriate, a suitable release agent was previously applied (not shown), whereby an impression of the profile of the die or mould 3 is formed in or on the flexible material 2, in this case in the form of the previously mentioned parallel cross members 4, which now appear as reinforcements in or on the flexible material 2.
  • FIG 2 shows an enlarged detail of the part indicated in Figure 1 with F2.
  • Figure 3 shows a practical variant 8 of the embodiment of Figure 1 .
  • the reinforcements are made by additionally containing several layers of folded material 9 one on top of the other in the textile fabric 2, which material 9, where appropriate, can consist of the previously separately folded actual textile fabric 2.
  • Figure 4 shows on a larger scale a partial section of an enlarged detail of the part indicated with F4 in Figure 3 .
  • These reinforcements 9 are introduced as insertions in the textile fabric 2 which, as is shown in Figure 1 , is furthermore locally reinforced with the reinforcements 6, thanks to the impregnation above and below.
  • the multiple composite reinforced parts 6, 9 are alternated in this case with non-reinforced parts 7, which consist of non-reinforced textile fabric 2.
  • Figure 5 schematically shows a cross-section according to line V-V of Figure 3 of the mattress support 8, consisting of the supporting and elastic structure shown in Figures 3 and 4 .
  • the hardened strips 12, formed, for example, by means of the impregnation 6 and the containment of the linen fabric 9 folded on itself under the influence of a force indicated with the arrow 10, can move freely with respect to one another, for example, by rotating as indicated in a simplified manner in the direction of the arrows 11.
  • Figure 6 shows a general perspective view of a mattress support 1 on which a vertical force is locally exerted in the direction of the arrow 13.
  • Said figure shows, simplified by line 14, how this local force followed over a local deformation is caught and distributed by several reinforcements 12, given that the reinforcements 12, which are in the preferred embodiment shown made up of a series of elastic strips separated by non-reinforced textile fabric 7, are interconnected in a physically interactive manner and as a result cooperate in a mechanical manner.
  • Figure 7 shows a section according to line VII-VII of Figure 6 of a reinforced part 12 on which a vertical force is exerted according to the arrow 13.
  • Figure 8 finally shows a perspective view of a supporting elastic construction 15 made as previously mentioned, assembled on a foam core 16 and a self-supporting frame 17 to form a composite mattress support 1 according to the invention.
