Den foreliggende opfindelse angâr en madras af skum-stof med to over hinanden liggende skumstofplader, der pâ de mod hinanden vendte flader hver har en b01geformet pro-filering, som hver har samme afstand mellem b01gebjerge og 5 b0lgedale, og hvor de to plader er lagt 10st oven pâ hinanden pâ èn sâdan mâde, at den ene plades b0lgebjerge rager ind i den anden plades b0lgedale.The present invention relates to a foam mattress having two superimposed foam sheets, each of which has a curved profile on each facing surface, each having the same distance between wall mountains and 5 waves, and the two sheets are laid 10st on top of each other in such a way that the waves of one plate protrude into the waves of the other plate.

En sâdan madras er kendt fra beskrivelsen til tysk brugsm0nster nr. 1796366. Ved den kendte madras kan de to 10 skumstofplader, som danner madrassen, pâ de mod hinanden vendende flader hâve listeformede forh0jninger af vilkâr-lig type, idet de modstâende forh0jninger griber ind mellem hinanden, nâr de lægges sammen. Med sâdanne lister og tilsvarende udtagninger skal der under en materialebespa-15 relse kunne opnâs en st0rre madrash0jde uden at fjedrings- komforten bliver eller skal blive pâvirket.Such a mattress is known from the specification for German Application No. 1796366. In the known mattress, the two 10 foam sheets forming the mattress can have, on opposite faces, molded elevations of any type, with the opposing elevations intervening between when they are put together. With such moldings and similar recesses, a greater mattress height must be achieved during a material saving without the spring comfort being or must be affected.

Derudover kendes der fra DE-OS nr. 24 05 405 en madras, pâ hvis mod hinanden vendende flader pâ hver af de to skumstofplader der er en savtakket profilering med en 20 lodret og en skrâ tandflanke og hvor man ved en horisontal forskydning af de to skumstofplader skal kunne indstille madrassen til forskellig hârdhed. Bortset fra, at denne madras ved forskelligt indstillet hârdhed ogsâ har forskellig h0jde, er der en risiko for en medglidning i sideretningen 25 af de to tandflader mod hinanden, hvorved den tilstræbte effekt meget hurtigt forsvinder igen,In addition, from DE-OS No. 24 05 405 a mattress is known on whose faces facing each other on each of the two foam sheets there is a sawed profiling with a 20 vertical and a sloping tooth flank and where a horizontal displacement of the two foam sheets must be able to set the mattress to different hardness. Apart from the fact that this mattress has different heights at different heights at different heights, there is a risk of co-slip in the lateral direction 25 of the two tooth surfaces towards one another, whereby the desired effect very quickly disappears again.

Den opgave, som s0ges l0st ved den foreliggende opfindelse, er at tilvejebringe en madras, som ait efter den optrædende belastning automatisk indstiller en st0rre hârd-30 hed og sâledes byder pâ en optimal liggekomforte Pâ basis af den indledningsvis omtalte kendte teknik tilvejebringes der til l0sning af den stillede opgave en madras, der if01ge opfindelsen er ejendommelig ved det i den keridetegnende del af krav 1 nævnte, 35 Ved en sâdan udformning af madrassen, ved hvilken afstanden mellem de enkelte b01gebjerge og -dale altid har 2The object solved by the present invention is to provide a mattress which, after the occurrence of load, automatically adjusts a greater hardness and thus offers an optimal lying comfort on the basis of the prior art mentioned prior art solution is provided. of the positioned task a mattress according to the invention is peculiar to that mentioned in the drawing-on part of claim 1, 35 In such a design of the mattress, at which the distance between the individual boulders and valleys always has 2

samme st0rrelse er i ubelastet tilstand kun toppene af bjergene af den h0jere profilering i ber0ring med dalene af den lavere profilering, medens de 0vrige flader ikke 5 ber0rer hinanden, men danner fri kanaler mellem de to del-madrasser. Ved en belastning vil i afhængighed af be-lastningens st0rrelse ber0ringsfladerne mellem de to del-madrasser stadig tiltage, efterhânden som st0rre omrâder af den 0vre og nedre madras kommer i ber0ring med hinanden.the same size, in the unstressed state, only the peaks of the mountains of the higher profile are in contact with the valleys of the lower profile, while the other surfaces do not touch each other but form free channels between the two part mattresses. At a load, depending on the size of the load, the contact surfaces between the two mattresses will still increase as larger areas of the upper and lower mattress come into contact with each other.

20 Herved fremkommer der en fjederkarakteristik, som svarer til at madrassen ved lav belastning er bl0d, men ved til-tagende belastning bliver hârdere, indtil det tidspunkt, hvor skummet bærer overalt. Herved opfanges bêlastningen langsomt, efterhânden som stadig mere af skummet kontinuer-25 ligt kommer til indbyrdes indgreb.20 This results in a spring characteristic which corresponds to the mattress at low load is soft, but at increasing load becomes harder until the time when the foam wears everywhere. Hereby, the loading load is slowly intercepted, as more and more of the foam continuously interacts with one another.

Til yderligere tilpasning til belastningen kan de to skumstofplader hâve forskellig st0dhârdhed og/eller forskel-lig rumvægt, hvorved der bliver yderligere mulighed for at variere hârdheden. Det er mest hensigtsmæssigt, at det er 20 pladen med den mindste profilering, der har st0rst st0d-hârdhed og er anbragt som underplade.For further adaptation to the load, the two foam sheets may have different stiffness and / or different room weight, thereby providing further opportunity to vary the hardness. It is most convenient that it is the plate with the least profiling that has the greatest shock hardness and is placed as a bottom plate.

For deruover at sikre en yderligere tilpasning, navnlig til ydre belastninger og en onsket hârdere opfprsel af madrassen er det muligt at den nedenunder liggende plade med storre 25 stodhârdhed i det midterste omrâde for hovedbelastningen har en indsats af skumstof med en yderligere storre stpdhârdhed.In addition, to ensure further adaptation, in particular to external loads and a desirable hardening of the mattress, it is possible that the plate below with greater 25 stiffness in the middle area of the main load has an insert of foam material with a further greater stiffness.

I forbindelse med en skematisk tegning er opbygningen og virkningsmâden for en madras ifplge opfindelsen nærmere belyst. Pâ fig. 1 er der sâledes vist et længdesnit gennem 30 en del af madrassen.In connection with a schematic drawing, the structure and mode of operation of a mattress according to the invention are further elucidated. In FIG. 1, a longitudinal section through a portion of the mattress is thus shown.

Ifplge det viste udforelseseksempel bestâr madrassen 1 af en 0vre skumstofplade 2 og en nedre skumstofplade 3.According to the embodiment shown, the mattress 1 consists of an upper foam plate 2 and a lower foam plate 3.

Den ovre skumstofplade 2 udviser en bplgeformet profilering med bplgebjerge 4 og bolgedale 5, mens den nedre plade 3 er 35 forsynet med en bolgeformet profil med mindre h0jde med bolge-bjerge 6 og bplgedale 7. De to skumstofplader 2 og 3 er nu lagt oven pâ hinanden pâ en sâdan mâde, at hver af bolgebjer-gene 4 henholdsvis 6 rager ind i bplgedalene 5 henholdsvis 3The upper foam plate 2 exhibits a wave-shaped profiling with bump mountains 4 and bulging valleys 5, while the lower plate 3 is provided with a lower-shaped wave-shaped profile with bulge mountains 6 and bale valleys 7. The two foam plates 2 and 3 are now superimposed on each other in such a way that each of the bolster mountains 4 and 6 respectively project into the bale valleys 5 and 3 respectively.

7 i den over for liggende pladen. Da nu den nedre plade 3 udviser en profilering med mindre hojde forbliver der mellem bolgebjergene 6 i denne nedre plade og bunden af b0lgedalene 5 i den 0vre plade 2 hulkanaler 8, der strækker sig over madras-5 sens 1 samlede bredde.7 in the opposite plate. Now that the lower plate 3 exhibits a lesser profile, there remains between the bulb mountains 6 in this lower plate and the bottom of the wave valleys 5 in the upper plate 2 hollow channels 8 extending over the total width of the mattress 5.

I almindelighed er opbygningen af madrassen valgt sâle-des, at den nedre plade 3 udviser en storre stodhârdhed end den 0vre plade 2, i almindelighed dog med samme rumvægt.In general, the structure of the mattress is chosen so that the lower plate 3 exhibits a greater stiffness than the upper plate 2, however, in general, with the same room weight.

Ved en belastning af madrassen opnâs der dermed en 3_g progressiv f jederkarakteristik, som svarende til det viste udforelseseksempel fprst kun den blodere plades 2 bolgebjer-ge 5 bærer. Nar sa disse b0lgebjerge 4 er trykket sâ vidt sammen, at b0lgedalene 5 kommer i beroring med bolgebjergene 6 i den nedre plade 3, og skumstoffet i den 0vre plade og den 15 nedre plade dermed stadig sammentrykkes mere, opnâs der dermed en stivere blivende fjedring afhængig af formen og bredden af proflieringen. Nâr endelig kanalerne 8 er trykket helt sammen, bærer den 0vre plades 2 samlede skumstofmateriale og den nedre plades 3 materiale. Da skumstofmaterialet ait i 20 ait svarende til den pâgældende diskrete belastning indtryk-kes forskelligt, opnâs der ait i ait med en sâdan madras en optimal punktelastisk afstotning.With a load on the mattress, a 3 g progressive spring characteristic is obtained, which, according to the embodiment shown above, only carries the 2 bolts of the bleeding plate 5. When these corrugated mountains 4 are compressed to such an extent that the corrugated valves 5 come into contact with the corrugated mountains 6 in the lower plate 3, and the foam in the upper plate and the lower plate is still more compressed, thus a stiffer spring suspension dependent of the shape and width of the profiling. Finally, when channels 8 are fully compressed, the upper sheet 2 carries the total foam material and the lower sheet 3 material. Since the foam material is pressed into 20 ait corresponding to the discrete load in question differently, an optimum point elastic repulsion is obtained with such a mattress.

Ved hjælp af den beskrevne udformning af madrassen og den forholdsvis ringe afstand imellem henholdsvis bplgebjer-25 ge og bolgedale er det til den fulde virkningsmâde for madrassen ikke nodvendigt med en speciel gitterrist der er afpasset efter placeringen af de enkelte profileringer, men der kan i grunden benyttes ethvert vilkârligt underlag. En yderligere fordel fordel ved denne madras bestâr i at der med den vedva-30 rende tværsnitsforandring af hulkanalerne 8 sikres en god tværbeluftning af madrassen, sâledes at en eventuelt stille-stâen af fugtighed og varme pâ sikker mâde kan undgâs.By means of the described design of the mattress and the relatively small distance between bpl mountain and bolgedale respectively, to the full mode of operation of the mattress is not necessary with a special grille that is adapted to the location of the individual profiles, but can basically any arbitrary substrate is used. A further advantage of this mattress is that, with the continuous cross-sectional change of the hollow ducts 8, a good cross-ventilation of the mattress is ensured, so that a possible standstill of moisture and heat can be safely avoided.

For at optimere virkningsmâden af de to pâ hinanden liggende plader 2 og 3 er disse plader kun lagt l0st pâ hinan-35 den. Til yderligere forbindelse kan der sâ blot pâ endesiden klæbes en tværgâende skumstofbjælke 9 til de to endesider af pladerne 2 og 3.In order to optimize the mode of action of the two adjacent plates 2 and 3, these plates are only loosely mounted on one another. For further connection, a transverse foam beam 9 can then simply be adhered to the two end sides of plates 2 and 3.

Til at opnâ en endnu hârdere karakteristik af madrassen er det sâ muligt, navnlig i de h0jt belastede omrâder af den nedre plade, ca. mellem de stiplede linjer 10, at indsætte et skumstofafsnit med endnu h0jere st0dhârdhed og eventuelt h0j-5 ere rumvægt.In order to obtain an even tougher characteristic of the mattress, it is then possible, especially in the high-stressed areas of the lower plate, approx. between the dashed lines 10, to insert a foam section with even higher shear strength and optionally higher-5 room weight.

Ved hjælp af den symmetriske profilering af de to pla-der er det ogsâ muligt at udf0re en affaldsfri fremstilling af disse madrasser, idet man da ved et enkelt b0lgeformet snit ud fra en kasseformet skumstofblok kan fremstille hen-10 holdsvis to ensartede overplader 2 eller to ensartede under-plader 3.By means of the symmetrical profiling of the two sheets it is also possible to carry out a waste-free manufacture of these mattresses, whereby a single wavy section from a box-shaped foam block can produce two uniform tops 2 or two respectively. uniform sub-plates 3.

Ved at anvende skumstof med forskellig st0dhârdhed, den samme eller forskellig rumvægt eller ogsâ ved at alene at anvende forskellig rumvægt kan man derved indstille madras-15 sen pâ forskellige hârdheder og fjederkarakteristikker. Da madrassen med samme virkningsmâde kan benyttes pâ begge sider kan man ogsâ dermed opnâ en forskellig hârdhedsfolelse i afhæn-gighed af om skumstoffet med den blodere eller med den hârdere stodhârdhed ligger overst.By using foam with different strengths, the same or different room weights or also by using different room weights alone, the mattress can be adjusted to different hardness and spring characteristics. Since the mattress with the same mode of action can be used on both sides, one can also achieve a different feeling of hardness depending on whether the foam with the bleed or with the harder stiffness is at the top.
