Definitions

  • This invention refers to the manufacturing field of elastic mattresses made of foamed materials and holding springs for getting a better support of human body during the rest period.
  • the main characteristic, that an efficient and ergonomic mattress must have, is the body support for guaranteeing a correct support to the spinal column during the rest period and the user's comfort necessary for a compete muscle relaxation, and it further avoids the formation of pressure points in which the blood does not circulate owing to excessive tissue compression.
  • the actually known spring mattresses supply the elastic support sometimes by steel springs or springs made of other materials, e.g. plastic material and natural or artificial fibres.
  • each spring is inserted singularly in a fabric sack that insulates it from the other ones.
  • This structure is characterised by its particular adaptability to the body form as, owing to the sack, each spring is relatively independent from the adjacent ones and then it supplies a differentiation of the body support thanks to the presence of a series of springs near and working in an independent manner with one another.
  • the springs can be completely independent (if they are not joined with one another) or relatively joined with one another in any manner and position.
  • connection of foam strata to the springs occurs by a mechanical process, e.g. clinching by metallic stitches or by glueing; these two operations are both costly as they require a rather long and tedious manual work and that must be made in the greater part manually by skilled workers.
  • the glueing operation can also compromise the mattress duration as using it for various years the glue can lose its adhesive capacity; further the manual glueings operation cannot be made in the correct manner or the glue cannot be applied in uniform manner on two pieces belonging to the same production lot or simply on the same piece.
  • the new system allows, if it is wished, to make different all of surfaces in areas having different densities or support capacities and forms for receiving in the more suitable manner the different human body zones in the rest position.
  • legs, shoulder zone, for getting a complete rest require a differentiated support and different absorption depth of the human body into the mattress.
  • the spring structure is inserted in a mold preferably made of aluminium alloy having dimensions slightly higher than the ones of the spring structure so that it remains an empty interspace between the mold and the structure in conjuction with each face, but not necessarily in conjuction with all faces.
  • One or many strata of any material can be put over the spring structure with the aim, for example, to insulate better the springs from the latex foam or to increase the mattress comfort or simply to increase its thickness.
  • the mold is closed hermetically by a cover on which there are applied "nozzles" suitably positioned so that they can inject the latex foam.
  • the latex foam injection establishes the filling of all of interspaces over, under and on the flanks of the spring structure, but not in the inside thereof, as the springs are sacked and the covering material causes them to become "impermeable" (completely or partially) against the latex foam, that is rather dense.
  • the surface, or the rest plane, can be smooth or machined for dividing the structure in zones; alveolar or filled; differentiated or equal on both sides.
  • the flanks can be filled or supplied with holes or machined.
  • composition and/or density of used latex foam can be changed in relation to characteristics of the finished product that it is wished.
  • the Figure 2 shows a typical structure of sacked springs as they are foreseen for the assembly of mattress of the present invention. It must be noticed that, in previous technics, these springs might be wound in wool or cotton wadding mass, or made of any other material foreseen for increasing the comfort.
  • the springs are wound by a proper material on each side, therefore they remain internally empty and then they can apply more efficiently the flexibility action on the user's body PE.
  • M shows the spring and EL shows the external material, of various compositions, but in any case impermeable (completely or partially) against the latex foam.
  • the Figure 3 shows a possible structure of a mattress made by the previous technics, that can be easily broken, as the various parts are glued, sawn or clinched and the same springs are glued or sewn or clinched in various manners to a sole latex stratum obtained precedently, then subject to breackages or to drawback of breakaway of glued, sewn or clinched parts.
  • the Figure 4 shows a possible hole structure suitable for getting the density variation.
  • the Figure 5 shows a possible mold structure for the injection 1 and the fulfilment of a mattress structure with springs embodied in the rubber latex, according to the present invention.
  • the mold is made up of the walls 2, 3, the wall 6 in the sheet plane and the wall 7 in the plane behind the sheet, a bottom 4, a cover 5 and the elements 8 for the aeration holes.
  • the bottom 4 or the cover 5, in its internal sides, are supplied with pins 11 having sections suitable for creating the differentiated holes of the mattress that were described with reference to Figure 4 and are laid on the faces 12 of the springs.
  • the springs 13 are sacked in any suitable material 14 ( Figure 6) for getting that the latex foam remains out (completely or partially) of the internal spring space. This allows a better flexibility and comfort.
  • the four lateral walls 2, 3, 6, 7 ( Figure 7) can be tilted in the moment of mattress extraction from the mold.
  • this material being a fabric, unweaved fabric, gauze, polyethylene, polyurethane, polyethylene, paper or any other material suitable for this aim, including jute, hemp, raffia and cotton, suitable to insulate the spring/s (completely or partially) with respect to the latex foam for avoiding that the spring/s is/are buried in latex foam and that in this manner the flexibility of the spring structure is reduced.
  • the Figure 6 shows the rest situation of springs 13, covered by impermeable material (completely or partially) onto latex foam 14 on all of sides.
  • the zones 20 adjacent to horizontal faces of springs are naturally filled with latex foam, therefore the springs are suspended on the pins 11 during the injection.
  • the pins 11 form also the support of springs for making them stable during the injection.
  • the Figure 7 shows a structure mold in perspective view in opened condition including the cover 5 and the pins for lateral aeration holes.
  • the shown mold includes a division wall 22 extractable/removable (preferably made of aluminium alloy), that allows to make the bed mattress for a sole person obtaining two mattresses contemporaneously, while extracting this wall it is possible to make a mattress for two persons with the same production modalities.
  • the cover 5 can be lifted for the insertion of springs into the mold and is closed and locked again when said load of springs is made.
  • the springs due to its weight and due to a light pressure applied by pins 11 remain stable during the injection.
  • the Figure 8 shows a possible final external structure of the mattress in a sole block with zones having different densities F1, F2, F3 substantially as the ones indicated in Figure 4, and indicates the holes 8 generated by pins 8, after having extracted the mattress from the mold. These holes make easier the air transpiration across the finished mattress.
  • the Figure 9 shows a further layout of the mattress in the mold with an internal structure UR made of various natural or artificial materials made of fibres or other expandable material, of polyurethane foam, or coco fibres or wool or polyester fibres for manufacturing a mattress in strata (sandwich) and/or with different zones.
