Definitions

  • the utility sample is a bed insert equipped with air-mattress by means of which a lying or if necessary sitting piece of furniture can be created with adjustable rigidity and the condition of which is kept also after being used for a long period.
  • the main characteristic of the mattresses is the lying surface ensured for the person using it.
  • the lying surface - depending on the type of the load- bearing construction - can have different springiness and rigidity as required by the user. According to the actual state of technology there are several different solutions regarding the inner load-bearing construction of beds.
  • the other widespread solution is the coverage of the lying surface with a thick coat of foam.
  • the disadvantage of this solution is that the foam becomes age-worn and porous, and the springiness of this mattress type also will be reduced on the much used parts.
  • the further disadvantage of both of the foam coat and that of the interior-sprung mattress is that their springiness can not be adjusted as required by the user.
  • a well-known solution for lying surfaces is the water-bed, in the case of which the lying as well as load-bearing surface of the bed is solved by means of a flexible tank filled with water.
  • This type of solution is published also in the publication document PCT No. WO 89/12414.
  • the springiness of the water-bed can be set by adjusting the water pressure of the tank.
  • the disadvantages of the water-bed is temperature stability and the inhibition of currents in the tank have to be solved, and the long usage of this type of mattress can be damaging to health.
  • patent No. US 5 170 522 introduces a bed which was produced using an air-mattress. Its drawback is that it is a complex and intricate structure. The air-mattress, used in this type of bed, does not make possible the universal and bed-independent usage.
  • the bed insert contains one or, if necessary, more air-mattress(es) surrounded by foam stiffeners, and above the air mattress(es) there is an upper foam layer, and the bed insert is fitted with a practical outer cover as well.
  • the utility sample is a bed insert equipped with an air-mattress and this bed insert has a load-bearing structure built-up by the application of air- mattresses.
  • the bed insert consists of one or, if necessary, more air- mattresses surrounded by foam stiffeners, and above the air mattress(es) there is an upper foam layer, and the bed insert is fitted with a practical outer cover as well.
  • the inner side of the lateral foam stiffeners are arched-shaped and they are equipped with cross ribs, and the horizontal size of the lateral foam stiffeners has to be at least 8 cm.
  • the bed insert has double air sealing, and includes air-mattresses divided into cells.
  • the figure 1. shows the segment of a possible structural design of the bed insert according to the sample.
  • the figure 2. shows the perspective drawing of a preferred inner design of the bed insert according to the sample.
  • the bed insert according to the sample to be seen in figure 1. shows the segment of a possible structural design.
  • the figure 1. shows the air-layers (1) which are surrounded by the lateral foam stiffeners (2), and between them there is a middle foam stiffener (3). Above the air-mattresses (1) there is the upper foam layer (4), and under them there is a bottom foam layer (5).
  • the bed insert designed in this way is fitted with an outer cover (6).
  • the bed insert to be seen in the figure 1. includes two air-mattresses (1) in an asymmetrical lay-out, the mattress, to be found on the left side, is narrower and the right one is broader.
  • the lay-out has different rigidity on the left and right side, and the result of this is a dynamic type lying surface.
  • the figure 2 shows the perspective drawing of the inner design of the utility sample.
  • the air-mattresses (1) to be seen are surrounded by lateral foam stiffeners (2), and between them there is a middle foam stiffener (3).
  • the outer cover (6) of the bed insert is to be seen also in section.
  • the air-mattresses (1) When lying on the mattress, the air-mattresses (1) will be squeezed in a mainly lateral direction, so it is important to assure the expansion possibility in a lateral direction. This can be achieved by the appropriate formation of the inner side of the lateral foam stiffeners (2), which makes possible the displacement in a lateral direction by means of the appropriate design of the inner side.
  • the width of the lateral foam stiffeners (2) is 8....20 cm
  • the thickness of the upper foam layer (4) is 0.5....10 cm.
  • the whole thickness of the bed insert is 15....25 cm. It is possible to apply air-mattresses on the two sides of the bed having different thickness, as this type of design makes possible the formation of a lying surface with an asymmetrical shape, different springiness and rigidity.
  • the air inlet to the air-mattresses (1) is solved by a filling tube built into the bed insert.
  • the other solution is when there is slot made in the mattress which makes access possible to the filling opening of the air-mattress (1) and which can be opened and closed by the well-known methods, for example by Velcro, zip fastener, press studs.
  • the air-mattresses (1) used in the sample bed insert are treated with ageing retarder and they are advantageously perfumed.
  • the mattress in the case of a concrete formation, can be used for making a sitting surface.
  • the air-mattress (1) has to be used in the required size.
  • the bed insert has adjustable rigidity, and in a special case, the rigidity of the bed insert can be dissimilar in different parts of the lying surface.
  • the springiness of the bed insert will not change during its usage period, and there is no concaving on the surface even after a long time of usage because of the property of the air-mattress.
  • Further advantage is that it can be widely applied, as well as the bed can be shaped depending on different requirements.
