Definitions

  • the invention relates to a mattress made of foam with two superimposed foam sheets.
  • Such a mattress is known from DE-A-2 405 405, in which the mutually facing surfaces of the two foam sheets each have a sawtooth profile with a vertical and an oblique tooth flank, and in the case of horizontal displacement, the two foam sheets have a different hardness of the mattress should be adjustable.
  • this sawtooth-shaped profile is different in the case of the two foam boards, since on one board both the highest and the lowest points of the profile are cut off horizontally, and on the other hand only the tips at the top are blunted.
  • this mattress can each have different hardness by horizontal displacement of the two plates, at the same time, however, results in the possibility of different heights of the overall mattress and there is the danger of a lateral Abrut - schens the superposed oblique tooth flanks so that so that the desired effect of a lower hardness with corresponding displacement of the plate to each other is canceled.
  • the present invention has for its object to provide a mattress that automatically has a greater hardness depending on the load and thus offers optimal comfort.
  • a mattress made of foam with two superimposed foam sheets is provided according to the invention, each of which has a profile that extends across the entire width of the mattress and has the same spacing of profile tips and profile valleys on their mutually facing surfaces, and the two foam sheets are loosely placed one on top of the other that the profile tips of one foam sheet protrude into the profile valleys of the other foam sheet, the profiling of both foam sheets extending according to a sinusoidal wavy line, the wavy line of one foam sheet having a greater amplitude than the wavy line of the other foam sheet and the wave crests of the foam sheet with the wavy line larger The amplitude of the tips lies at the deepest point in the wave troughs of the foam sheet with the wave line of smaller amplitude.
  • the two foam sheets only touch each other in a linear manner at the tips of the wave crests of the wave line of larger amplitude and the wave troughs of the wave line of smaller amplitude, while the rest are in the unloaded state Do not touch surfaces, but form free channels between the two foam sheets.
  • the contact area between the two foam sheets will increase steadily in accordance with the applied load, as more and more areas of the upper and lower sheets come into contact with one another. This initially results in a soft spring characteristic, which becomes harder with increasing load until the point at which the foam is fully supported. The strain is slowly absorbed as more and more foam interacts with one another.
  • the foam sheet with the wavy line of smaller amplitude has a greater compression hardness than the foam sheet with the wavy line of larger amplitude.
  • the foam sheet lying below it is also possible for the foam sheet lying below to have an insert made of foam with an additional compression hardness in the central region of the main load.
  • Another major advantage of the mattress designed in this way is that, with a corresponding symmetrical profile of the profiles from a cuboid base plate, two top plates or two bottom plates of the same profile can be manufactured without waste by a single cut.
  • Fig. 1 shows a longitudinal section through part of the mattress.
  • the mattress 1 consists of an upper foam sheet 2 and a lower foam sheet 3.
  • the upper foam sheet 2 has an undulating profile with wave crests 4 and wave troughs 5, while the lower plate 3 with an undulating profile of lower height with the wave crests 6 and the troughs 7 is provided.
  • the two foam sheets 2 and 3 are now placed one on top of the other so that the crests 4 and 6 respectively protrude into the troughs 5 and 7 of the opposite plate. Since the lower plate 3 now has a lower profile, hollow channels 8 remain between the crests 6 of this lower plate and the bottom of the troughs 5 of the upper plate 2, which extend over the entire width of the mattress 1.
  • the structure of the mattress is chosen so that the lower plate 3 has a greater compression hardness than the upper plate 2 - but generally with the same density.
  • a slatted frame specially tailored to the position of the individual profiles is not necessary for the full operation of the mattress, but basically any base can be used.
  • Another advantage of this mattress is that the constant change in cross-section of the hollow channels 8 ensures good cross-ventilation of the mattress, so that a possible build-up of moisture and heat is safely avoided.
  • transverse foam bar 9 can then be glued to the two end faces of the plates 2 and 3 only on the end faces.
  • both the wave crests 12 and the wave troughs 13 have a V-shaped course, with the V-tips 15 in the middle of the mattress width lie.
  • the two plates are placed one on top of the other in such a way that the wave crests of one plate protrude into the troughs of the other plate.
  • this mattress has the advantage that it is harder in the middle area because of the material accumulation there than in the side areas. The manufacture of this mattress is the same as that of the straight profile.
