Definitions

  • the present invention relates to a supporting mattress for conventional mattresses of a kind as stated in the preamble of the following independent claim 1.
  • the above mentioned supporting mattress is intended to be underlaying a common spring mattress or a foamed plastic mattress so as to enhance the springiness of the latter, when subjected to a load.
  • springiness of spring mattresses and other mattresses is limited by stationary bed boards.
  • resilient bed board means e.g. lattice means were designed.
  • Such a bed lattice system may, e.g. in a case of a known commercially available means comprise thin, often laminated list members or ribs of a slightly curved shape which provides a bias, such list members being placed with their convex face upwards in a bed frame to form a support which is convex upwards across the longitudinal direction of the bed.
  • Such list members may also be mounted to be resilient/springy towards the sides of the bed frame. In this manner a springy bed support is achieved which permits the underside of the mattress to be shaped in accordance with varying loads exerted on the mattress by different parts of the body of a lying person.
  • the lumped load on a conventional mattress which is supported by said supporting mattress will automatically be transferred to other portions of the mattress to increase the counter pressure there correspndingly. In this manner, not only a more pronounced support is achieved, but also a more active mattress which will displace the counter pressure or support at the slightest movement by the person lying on it.
  • the aid of the supporting mattress according to the present invention it was possible to utilize the advantages of water beds, becoming more and more acknowledged, for conventional mattresses. Quality of sleep is experienced differently, some people prefer a water bed, others find a traditional mattress to be the best alternative.
  • the advantages of a water bed and a traditional mattress may be combined.
  • the support mattres as shown in the drawings, and especially in Figure 1, comprises a mattress base 1 having a flat underside 2, and an upper side 3 with a recess 4 which extends over a substantial portion of the length and width of mattress base 1, and is defined by resiliently compressible rims 5.
  • the top surface 6a of water bag 6 is flush with upper surfaces 5a of the resiliently compressible edges 5 and will, combined with the latter, form a supporting surface for a conventional mattress, when the supporting mattress is placed in a bed frame with a rigid bed board arrangement, or on another rigid foundation.
  • the height of the supporting mattress is less than that of a conventional mattress, preferably, it is substantially less, so that the volume of water in water bag 6 is in the order of 40-60 litres.
  • a supporting mattress of this kind will, thus, be so lightweight that it may be used in any bed having a rigid bottom which serves as a foundation of all kinds of tradi­ tional mattresses.
  • a supporting mattress of the above mentioned kind may be sold at a reasonable price, since it does not need electrical heating, the user being kept isolated from the water bag 6 by the aid of the conventional mattress placed on top of the supporting mattress.
  • the supporting mattress naturally, may be provided with an electric heater, as shown in Figure 4, where the heating element is designated 9.
  • the insignificant water content of the supporting mattress represents a minimum hazard in case of a leakage.
  • the supporting mattress is not very heavy, and it may readily and inexpensively be stored and transported, as it is possible to roll/fold it up and pack it in a handy packing.
  • mattress base 1 comprises a sheet 2a of a rigid or soft foamed plastic material or a thin fibreboard which is preferably divided into a number of sections 2c, 2d, 2e, 2f, 2g, as shown in Figures 1, 4, and 5, said sections being hinged together, e.g. by the aid of folding lines 2b, so that the total size of the sections corresponds to that of a conventional mattress size.
  • a rim 5 of a resiliently compressible material, e.g. foamed plastic material is secured.
  • Rims 5 and bottom plate 2a define the recess 4 in which water bag 6 is placed.
  • Water bag 6 may be of a conventional design, but it is substantially slimmer (more shallow) with a water depth of only approximately 4-7 cm.
  • the resiliently compressible rims 5, e.g. consisting of foamed plastic, may be attached to bottom plate 2a of mattress base 1, e.g. by the aid of an adhesive.
  • Said rims 5 may have an oblique wall 5b extending from top face 5a of rim 5 and inwards into recess 4 in order to provide a smooth transition for the water bag 6 from bottom plate 2a of the mattress base to top face 5a of the lateral edges.
  • mattress base 1 with water bag 6 of the supporting mattress is enveloped by a tensioned mattress cover 8 contributing to hold together the components of the supporting mattress in use, and during folding operations for storage or transport.
  • mattress cover 8 may be produced from a preferably waterproof, flexible material forming a container which comprises a bottom 8a with upward side walls 8b, c, d, e, and extended flaps 8b′, c′, d′, and e′.
  • extended flaps will form the top of mattress cover 8, as shown in Figure 7.
  • the extended flaps are preferably provided with fastening means to be joined in a closed state, e.g. of the hook and loop cloth type.
  • Figures 8 and 9 show an alternative embodiment of mattress base 1.
  • the mattress base comprises a foamed plastic sheet 2a with compressed material on one face forming a substantially tight skin 7 on the opposite side of the face with flexibly compressible rims 5.
  • Plate 2a with said rims 5 in its position for use is provided with said rims 5 facing down, and with water bag 6 placed against skin 7 of the foamed plastic sheet facing upwards.
  • water bag 6 will then force the face of the foamed plastic sheet with skin 7 down between said compressible rims 5 and provide a recess 4 for water bag 6, as shown in Figure 9, when mattress base 1 is placed upside down in a bed frame with a bed boards arrangement 10.
  • Skin 7 may, if it is not waterproof, be treated in a suitable manner to achieve a waterproof condition, so that any leakage from water bag 7 will be caught inside recess 4 in mattress base 1.
  • the advantage of the above disclosed alternative embodiment of mattress base 1 is that it may be manufactured from a foamed plastic web, which is in production automatically provided with a compressed exterior layer on its top and bottom, respectively, as it is passing through a fashioning tunnel, where said skin is formed.
  • the foamed plastic web with a skin on both sides is split into two equal halves and is cut into lengths cor­responding to desired lengths of mattresses. Then the manufactured foamed plastic members may be subjected to a cutting operation for cutting a recess 4′ into the split faces, i.e. opposite to their faces which are provided with a skin 7. In this manner the resiliently compressible lateral rims 5 will be automatically formed and will define recess 4′ of mattress base 1, which recess corresponds to recess 4 in Figures 1 and 4.
  • mattress base 1 is turned upside down for use, as shown in Figure 9, so that said recess 4′ is flattened when water bag 6 is placed on top of mattress base skin 7 and forces the central portion of mattress base 1 down, so that a recess 4 is formed on top of skin 7, which recess 4 corresponds to the recess shown in Figures 1 and 4.
  • a mattress base recess 4 which is made waterproof by the aid of skin 7 at the production stage, or may be made waterproof by a further waterproof film which is glued to the surface or by the aid of a waterproof coating material which cures on the face.
