Definitions

  • This invention relates to a slatted bedstead, particularly for orthopaedic beds, and a slat used in the said bedstead.
  • a slatted bedstead consists of a plurality of slats or bars, usually made of strips of wood, the ends of which rest on a rigid frame.
  • the slats are made of flexible wood and normally have a bowed shape, with the concavity facing downwards, so that under the user's weight they tend to bend and curve in the opposite direction.
  • the compliance of the bedstead is provided by the deformation of the slats loaded with the user's weight; this deformation is always limited and not very adaptable to the shape of the body, either lengthways or transversely.
  • Bedsteads have also been proposed in which the slats or bars are substantially rigid or inflexible, and rest at the ends or elastically compliant supports.
  • These supports may, for example, be made of moulded rubber and constrain the ends of each slat to the fixed structure of the bedstead.
  • the said compliant supports are constituted by tubes of elastic material filled with a fluid of appropriate density, so that the weight of the person lying on the bedstead crushes the tubes most in correspondence with the slats subjected to most stress, and crushes them far less, if at all, or even leaves a "swelling", in correspondence with the slats not under load.
  • the said compliant supports at the ends of the slats are constituted by structural sections made of elastically deformable plastic or a combination of deformable plastic structural sections and fluid-filled tubes in order to increase the response time to the stresses which are generated by a body lying on the bedstead or caused by relatively abrupt movements, and therefore reduce the "oscillation" phenomenon caused by movements of the liquid in the tubes in the both directions, of decreasing extent.
  • the fact that the slats are substantially rigid or inelastic prevents the bedstead from adapting to the user's body in the transverse direction because the deformation has a bowed shape, and very thick mattresses are consequently required to make the bed comfortable.
  • bedsteads different from the slatted type described above to which the invention relates, have a rigid frame and a plurality of flexible bands or cables constrained at the ends to the said frame.
  • This bedstead is substantially different from the slatted type, and presents the same drawbacks as slatted bedsteads with a rigid frame, although its transverse adaptability is improved.
  • GB990241A describes a plurality of slats for a bed, according to the preamble of claim 1, comprising a substantially rigid tensioning element and elastic elements pre-tensioned by said tensioning element.
  • the purpose of the invention is to eliminate the drawbacks of the bedsteads described above, especially for orthopaedic beds, by combining the advantages of one with those of the others to obtain good longitudinal and transverse adaptability while using mattresses of lesser thickness.
  • one purpose of the invention is to provide a highly ergonomic slatted bedstead that adapts perfectly to the user's body in the different positions adopted during rest.
  • Another purpose of the invention is to provide such a slatted bedstead which is simple and cheap to manufacture, and in particular obtainable from bedsteads with conventional supports merely by changing the conformation of the slats.
  • the invention also relates to a slat usable in such a bedstead which presents the characteristics described in the annexed independent claim 11, and an orthopaedic bed made with such a bedstead in accordance with claim 12.
  • the bedstead in accordance with the invention comprises a plurality of slats resting at the ends on elastically compliant supports, wherein each slat comprises at least one substantially rigid tensioning element 10 and at least one flexible elastic element with fixed tension, the ends of which are constrained to the ends of the said tensioning element.
  • the tensioning element will have a curved shape, with the concavity facing upwards, namely towards the said at least one flexible element which is pre-tensioned by the tensioning element.
  • the tensioning element can be made of wood, curved plywood, moulded thermoplastic material, one or more steel rods, sheet steel or the like, while the flexible element consists of a belt or cable which has some degree of elasticity but is very tough, being made, for example of nylon, kevlar, teflon, rayon or the like.
  • the elastically compliant supports may be moulded rubber supports which constrain the ends of each slat to a rigid frame, or elastically compliant longitudinal members on which the ends of the slats rest.
  • the said elastically compliant longitudinal members may in turn consist of (i) tubes filled with a fluid of appropriate density (gel), (ii) elastically deformable plastic (polyurethane/latex foam), or (iii) a tubular combination filled with fluid and compliant plastic.
  • each slat in accordance with the invention is highly flexible and its ends rest on the elastically compliant supports, it adapts ergonomically to the positions adopted by the user in the bed.
  • Figure 1 illustrates, highly schematically and in partial view, a slatted orthopaedic bedstead in accordance with the invention, globally indicated as no. 1.
  • Bedstead 1 comprises a plurality of slats 2, the structure of which will be described in greater detail by reference to figures 3 to 7, the ends 3 of which slats rest on the longitudinal members 4 of a supporting frame.
  • the supports of slats 2 will also be more particularly described hereafter by reference to figures 8 to 11.
  • each slat 2 comprises a curved tensioning element 10 with the concave side facing upwards, the ends of which are connected on the concave side to at least one pre-tensioned elastic element 11.
  • tensioning element 10 consists of a curved bar made of wood, in particular plywood, or a moulded thermoplastic panel, and there are a plurality of elements 11 consisting of cables made of an elastic but very tough material such as nylon, kevlar, teflon or the like.
  • tensioning element 10 includes two steel rods that bear ends 3 of the slat to which elastic cables 11 are fixed.
  • the tensioning element consists of a steel sheet which is also fitted below elastic cables 11.
  • the embodiment shown in figure 6 includes two elastic belts 11, conveniently made of the same materials as the above-mentioned cables, with tensioning element 10, made of plywood or moulded plastic as shown in figure 3, fitted below them.
  • the embodiment shown in figure 7 includes a single elastic belt 11, held taut by the tensioning element 10 shown in figures 6 and 3.
  • Slats 2 are attached to longitudinal members 4 via elastically compliant supports.
  • elastically compliant supports 20 made of moulded rubber are fitted at ends 3 of each slat 2, and the said supports are attached in turn to longitudinal members 4.
  • support 20 is a block of rubber with large through apertures 21, which enables them to yield elastically at the point where a force is exerted, and two cavities 22 destined to house a corresponding end 3 of slat 2, which has a central slot 13 for this purpose.
  • Support 20 can be attached to a corresponding longitudinal member 4 via rods 23.
  • the elastically compliant support on which ends 3 of slats 2 rest consists of a structural section 120 made of elastically deformable plastic such as polyurethane or latex foam, which said structural section is housed in longitudinal members 4 and projects above them.
  • the elastically compliant support consists of a tube of elastic material 220 containing a gel, which extends along the whole length of longitudinal members 4.
  • elastically compliant support 320 is a combination of plastic structural section 120 illustrated in figure 9 and gel-filled tube 220 illustrated in figure 10.
  • slat 2 ends 3 of which rest on elastically compliant supports 20, 120, 220 and 320, which said slat consists of a tensioning element 10 and elastic elements 11, adapts perfectly to the user's positions.
  • the orthopaedic bedstead in accordance with the invention therefore presents considerable advantages over the slatted bedsteads described above.
