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.

Description
Die Erfindung betrifft eine Matratze aus Schaumstoff mit zwei übereinanderliegenden Schaumstoffplatten.The invention relates to a mattress made of foam with two superimposed foam sheets.
Eine derartige Matratze ist aus der DE-A-2 405 405 bekannt, bei der die einander zugewandten Flächen der beiden Schaumstoffplatten je eine sägezahnförmige Profilierung mit einer senkrechten und einer schrägen Zahnflanke aufweisen und bei der durch horizontale Verschiebung die beiden Schaumstoffplatten eine unterschiedliche Härte der Matratze einstellbar sein soll. Diese sägezahnförmige Profilierung ist jedoch bei beiden Schaumstoffplatten unterschiedlich, da einmal bei einer Platte sowohl die höchsten als auch die tiefsten Stellen der Profilierung horizontal abgeschnitten sind, und zum anderen bei der anderen Platte lediglich die Spitzen oben abgestumpft sind. Diese Matratze kann zwar durch horizontale Verschiebung der beiden Platten jeweils unterschiedliche Härte aufweisen, gleichzeitig ergibt sich dabei aber auch eine unterschiedliche Höhe der Gesamtmatratze und es besteht die Gefahr eines seitlichen Abrut- schens der aufeinanderliegenden schrägen Zahnflanken, so daß damit der angestrebte Effekt einer geringeren Härte bei entsprechender Verschiebung der Platte zueinander wieder zunichte gemacht wird.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. However, 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. Although 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.
Demgegenüber liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine Matratze zu schaffen, die je nach auftretender Belastung selbsttätig eine größere Härte aufweist und somit einen optimalen Liegekomfort bietet.In contrast, 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.
Zur Lösung dieser Aufgabe ist erfindungsgemäß eine Matratze aus Schaumstoff mit zwei übereinanderliegenden Schaumstoffplatten vorgesehen, die auf ihren einander zugewandten Flächen je eine sich über die gesamte Breite der Matratze erstreckende Profilierung mit jeweils gleichen Abständen von Profilspitzen und Profiltälern aufweisen und die beiden Schaumstoffplatten lose so aufeinandergelegt sind, daß die Profilspitzen der einen Schaumstoffplatte in die Profiltäler der anderen Schaumstoffplatte ragen, wobei die Profilierung beider Schaumstoffplatten entsprechend einer sinusförmigen Wellenlinie verläuft, die Wellenlinie der einen Schaumstoffplatte eine größere Amplitude als die Wellenlinie der anderen Schaumstoffplatte aufweist und die Wellenberge der Schaumstoffplatte mit der Wellenlinie größerer Amplitude mit ihren Spitzen an der tiefsten Stelle der Wellentäler der Schaumstoffplatte mit der Wellenlinie kleinerer Amplitude aufliegen.To achieve this object, 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.
Bei einer derartigen Ausbildung der Matratze mit einer Profilierung entsprechend einer sinusförmigen Wellenlinie unterschiedlicher Amplitude an den beiden Schaumstoffplatten berühren sich im unbelasteten Zustand die beiden Schaumstoffplatten nur linienförmig an den Spitzen der Wellenberge der Wellenlinie größerer Amplitude und den Wellentälern der Wellenlinie kleinerer Amplitude, während sich die übrigen Flächen nicht berühren, sondern freie Kanäle zwischen den beiden Schaumstoffplatten bilden. Bei einer Belastung wird nun jeweils entsprechend der aufgebrachten Last die Berührungsfläche zwischen den beiden Schaumstoffplatten stetig zunehmen, da immer mehr Bereiche der oberen und der unteren Platte miteinander in Berührung kommen. Dadurch ergibt sich zunächst eine weiche Federkennlinie, die mit zunehmender Belastung härter wird, bis zu dem Zeitpunkt, wo der Schaum vollständig trägt. Damit wird die Belastung langsam abgefangen, da kontinuierlich immer mehr Schaum miteinander in Eingriff kommt.With such a configuration of the mattress with a profile corresponding to a sinusoidal wave line of different amplitude on the two foam sheets, 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. When there is a load, 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.
Zur weiteren Anpassung an die Belastung ist es darüber hinaus zweckmäßig, wenn die Schaumstoffplatte mit der Wellenlinie kleinerer Amplitude eine größere Stauchhärte als die Schaumstoffplatte mit der Wellenlinie größerer Amplitude aufweist. Darüber hinaus ist es auch möglich, daß die unten liegende Schaumstoffplatte im mittleren Bereich der Hauptbelastung einen Einsatz aus Schaumstoff zusätzlich höherer Stauchhärte aufweist.To further adapt to the load, it is also expedient if 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. In addition, 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.
Ein weiterer wesentlicher Vorteil der so gestalteten Matratze ergibt sich dadurch, daß bei einem entsprechenden symmetrischen Verlauf der Profilierungen aus einer quaderförmigen Grundplatte durch einen einzigen Schnitt jeweils zwei Oberplatten oder zwei Unterplatten gleicher Profilierung ohne Abfall fertigbar sind.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.
Anhand schematischen Zeichnungen sind Aufbau und Wirkungsweise einer Matratze nach der Erfindung näher erläutert. Fig. 1 zeigt ein Längsschnitt durch einen Teil der Matratze.The structure and mode of operation of a mattress according to the invention are explained in more detail using schematic drawings. Fig. 1 shows a longitudinal section through part of the mattress.
Nachdem dargestellten Ausführungsbeispiel besteht die Matratze 1 aus einer oberen Schaumstoffplatte 2 und einer unteren Schaumstoffplatte 3. Die obere Schaumstoffplatte 2 weist dabei eine wellenförmige Profilierung mit Wellenbergen 4 und Wellentälern 5 auf, während die untere Platte 3 mit einer wellenförmigen Profilierung geringerer Höhe mit den Wellenbergen 6 und den Wellentälern 7 versehen ist. Die beiden Schaumstoffplatten 2 und 3 sind nun so aufeinandergelegt, daß jeweils die Wellenberge 4 bzw. 6 in die Wellentäler 5 bzw. 7 der jeweils gegenüberliegenden Platte ragen. Da nun die untere Platte 3 eine Profilierung geringerer Höhe aufweist, verbleiben zwischen den Wellenbergen 6 dieser unteren Platte und dem Grund der Wellentäler 5 der oberen Platte 2 Hohlkanäle 8, die sich über die gesamte Breite der Matratze 1 erstrecken.According to the exemplary embodiment shown, 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.
Im allgemeinen ist der Aufbau der Matratze so gewählt, daß die untere Platte 3 eine größere Stauchhärte als die obere Platte 2 - im allgemeinen jedoch bei gleichem Raumgewicht - aufweist.In general, 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.
Bei einer Belastung der Matratze ergibt sich somit eine progressive Federkennlinie, da - entsprechend dem dargestellten Ausführungsbeispiel - zunächst nur die Wellenberge 4 der weicheren Platte 2 tragen. Wenn dann diese Wellenberge 4 soweit zusammengedrückt sind, daß die Wellentäler 5 mit den Wellenbergen 6 der unteren Platte 3 in Berührung kommen, und damit immer mehr Schaumstoff der oberen Platte und der unteren Platte zusammengedrückt wird, ergibt sich somit eine, abhängig von der Form und der Weite der Profilierung, steifer werdende Federung. Wenn schließlich die Kanäle 8 ganz zusammengedrückt sind, trägt das gesamte Schaumstoffmaterial der oberen Platte 2 und das Material der unteren Platte 3. Da insgesamt das Schaumstoffmaterial entsprechend der jeweiligen diskreten Belastung unterschiedlich eingedrückt wird, ergibt sich insgesamt mit einer derartigen Matratze eine optimale punktelastische Abstützung.When the mattress is loaded, a progressive spring characteristic results, because - in accordance with the embodiment shown game - initially only wear the wave crests 4 of the softer plate 2. If these wave crests 4 are then compressed so far that the wave troughs 5 come into contact with the wave crests 6 of the lower plate 3, and thus more and more foam of the upper plate and the lower plate is compressed, this results in a, depending on the shape and the width of the profiling, stiffer suspension. When the channels 8 are finally pressed together, the entire foam material of the upper plate 2 and the material of the lower plate 3 are supported. Since the foam material is pressed in differently in accordance with the respective discrete load, an optimal point-elastic support results overall with such a mattress.
Durch die beschriebene Ausbildung der Matratze und die relativ geringen Abstände der Wellenberge bzw. Wellentäler voneinander ist für die volle Wirkungsweise der Matratze auch ein speziell auf die Lage der einzelnen Profilierungen abgestimmter Lattenrost nicht erforderlich, sondern es kann im Grunde jede beliebige Unterlage benutzt werden. Ein weiterer Vorteil dieser Matratze besteht darin, daß durch die dauernde Querschnittsveränderung der Hohlkanäle 8 eine gute Querbelüftung der Matratze gewährleistet ist, so daß ein evtl. Stau von Feuchtigkeit und Wärme sicher vermieden wird.Due to the described design of the mattress and the relatively small distances between the crests or troughs from one another, 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.
Um die Wirkungsweise der beiden aufeinanderliegenden Platten 2 und 3 zu optimieren, sind diese Platten nur lose aufeinandergelegt. Zur zusätzlichen Verbindung kann dann lediglich an den Stirnseiten ein querverlaufender Schaumstoffbalken 9 mit den beiden Stirnseiten der Platten 2 und 3 verklebt werden.In order to optimize the operation of the two plates 2 and 3 lying on top of one another, these plates are only placed loosely on top of one another. For the additional connection, a transverse foam bar 9 can then be glued to the two end faces of the plates 2 and 3 only on the end faces.
Für eine noch härtere Charakteristik der Matratze ist es dabei möglich, insbesondere in den hochbelasteten Bereichen in der unteren Platte 3, etwa zwischen den gestrichelten Linien 10 einen Schaumstoffabschnitt mit noch höherer Stauchhärte und evtl. höherem Raumgewicht einzusetzen.For an even harder characteristic of the mattress, it is possible to use a foam section with an even higher compression hardness and possibly higher density, especially in the highly stressed areas in the lower plate 3, for example between the
Durch die symmetrische Profilierung der beiden Platten ist auch eine abfallose Herstellung dieser Matratzen möglich, da dann durch einen einzigen wellenförmigen Schnitt aus einem quaderförmigen Schaumstoffblock jeweils 2 gleichartige Oberplatten 2 bzw. Unterplatten 3 anfallen.Due to the symmetrical profiling of the two plates, a waste-free production of these mattresses is also possible, since then two identical top plates 2 and bottom plates 3 are obtained from a cuboid foam block through a single undulating cut.
Durch die Verwendung von Schaumstoff unterschiedlicher Stauchhärte gleichen oder unterschiedlichen Raumgewichtes oder aber auch unterschiedlichen Raumgewichtes allein, lassen sich somit auch unterschiedliche Härten und Federkennlinien der Matratze einstellen. Da die Matratze bei gleicher Wirkungsweise beidseitig benutzbar ist, stellt sich dann auch jeweils ein unterschiedliches Härtegefühl ein, je nachdem, ob der Schaumstoff mit der weicheren oder der härteren Stauchhärte oben liegt.By using foam of different compression hardness of the same or different density or also different density alone, different hardness and spring characteristics of the mattress can be set. Since the mattress can be used on both sides with the same mode of action, there is a different feeling of hardness, depending on whether the foam with the softer or the harder compression hardness is on top.
Bei dem in Fig. 2 dargestellten Ausführungsbeispiel, das einen Blick auf die untere Platte 14 einer Matratze 11 zeigt, weisen sowohl die Wellenberge 12 als auch die Wellentäler 13 einen V-förmigen Verlauf auf, wobei die V-Spitzen 15 in der Mitte der Matratzenbreite liegen. Auch hierbei sind die beiden Platten so aufeinandergelegt, daß die Wellenberge der einen Platte in die Wellentäler der anderen Platte ragen. Bei dieser Gestaltung ergeben sich ebenfalls durchgehende Kanäle für eine gute Durchlüftung. Zusätzlich hat diese Matratze noch den Vorteil, daß sie im mittleren Bereich wegen der dort vorhandenen Materialanhäufung härter ist als in den Seitenbereichen. Die Herstellung dieser Matratze ist dabei die gleiche wie bei der mit gerade durchgehender Profilierung.In the embodiment shown in FIG. 2, which shows a view of the
