Description

Dei Erfindung betrifft ein Polsterelement für ein Liege- oder Sitzmöbel gemäss dem Oberbegriff des Anspruchs 1. Derartige Polsterelemente können insbesondere als Obermatratzen in Betten eingesetzt werden, aber auch als Sitz- oder Rücklehnenpolster in Sitzmöbeln. Bei derartigen Elementen muss wegen der unvermeidlichen diffusionsbedingten Verluste der Luftkern regelmässig nachgefüllt werden.The invention relates to a cushion element for a couch or Seating furniture according to the preamble of claim 1. Such upholstery elements can in particular as Upper mattresses can be used in beds, but also as Seat or backrest upholstery in seating. With such Elements must because of the inevitable diffusion Air core losses are regularly replenished.

Aus der US-A-4 306 322 ist ein gattungsgemässes Polsterelement bekannt, das als Obermatratze ausgebildet ist mit einem ausklappbaren integrierten Pumpenkörper, welcher über ein Einwegventil und ein umstellbares Dreiwegventil direkt mit dem Luftkern der Matratze verbunden ist. Zum Nachfüllen des Luftkerns wird der Pumpenkörper ausgeklappt und manuell komprimiert.From US-A-4 306 322 is a generic Upholstery element known, which is designed as a top mattress with a fold-out integrated pump body, which via a one-way valve and a convertible three-way valve is directly connected to the air core of the mattress. To the The pump body is folded out to refill the air core and compressed manually.

Bei Systemen dieser Art muss der Luftdruck im Luftkern verhältnismässig häufig durch manuelles Pumpen nachgeführt werden. Dabei kann es verhältnismässig leicht vorkommen, dass der Luftkern überfüllt wird und zu hart ist, so dass wiederum Luft durch das Dreiwegventil abgelassen werden muss. Durch die Notwendigkeit häufigen manuellen Nachpumpens und die Schwierigkeit, den Druck manuell richtig einzustellen ist das System unbequem in der Bedienung.In systems of this type, the air pressure in the air core relatively often tracked by manual pumping will. It can be relatively easy that the air core gets overfilled and is too hard, so that again air can be discharged through the three-way valve got to. Due to the need for frequent manual pumping and the difficulty of manually printing correctly the system is uncomfortable to use.

Aufgabe der Erfindung ist es, ein gattungsgemässes Polsterelement zu schaffen, bei dem der Luftkern automatisch dosiert nachgespeist wird. Dieses Aufgabe wird durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale gelöst. Weitere Merkmale der Erfindung sind Gegenstand der abhängigen Ansprüche 2 bis 10. The object of the invention is a generic To create cushioning element in which the air core automatically dosed is replenished. This task is accomplished by the specified in the characterizing part of claim 1 Features resolved. Other features of the invention are the subject of dependent claims 2 to 10.

Beim erfindungsgemässen Polsterelement wird stets nur so viel Luft in den Luftkern nachgeliefert, wie erforderlich ist, um einen bestimmten Innendruck in demselben aufrechtzuerhalten. Es kann leicht so ausgebildet werden, dass der Innendruck und damit die Härte des Luftkerns über einen weiten Bereich stufenlos regelbar ist. Die Nachfüllung kann vollständig automatisch erfolgen, so dass ein manuelles Nachpumpen in aller Regel nicht erforderlich ist. In the upholstery element according to the invention, this is always the only way lots of air is added to the air core as required is to a certain internal pressure in the same maintain. It can easily be trained that the internal pressure and thus the hardness of the air core over a wide range is continuously adjustable. The refill can be done completely automatically, so a manual Post-pumping is generally not necessary.

Funktkionsweise:Functionality:

Bei Belastung der Obermatratze entsteht durch das Körpergewicht des Benützers zonenweise Belastungsdruck. Dieser, bei Anfangs oder Endbenützung insbesondere im Randbereich der Obermatratze verstärkt auftretende Druck presst Luft aus den integrierten Pumpenkörpern (1) in das unbelastete Luftreservoir (2). Die beiden Einwegventile (3) bewirken das Strömen der Luft in stets nur einer Richtung. Die aus den Pumpenkörpern (1) verdrängte Luft wird im Luftreservoir (2) komprimiert und dient als Reserve. Diese komprimierte Luftreserve gleicht den Druck im Luftkern (4) bis zu jenem Wert aus, welcher anhand der Skala (6) am Druckregulierventil (5) eingestellt wurde. Dieser Ausgleich geschieht spätestens bei Entlastung der Obermatratze. Wird die Randzone entlastet, saugen die Pumpenkörper (1) durch die Rückkehr in ihre Ausganglage, Umgebungsluft durch das eine Ventil. Die Pumpe ist damit für weitere Luftspeisung bereit. Das einstellbare Druckregulierventil (5) sorgt zusammen mit der im Luftreservoir (2) komprimierten Luft für genau dosierte Nachspeisung im Luftkern (4). Die Skala (6) erlaubt genaue Einstellung des gewünschten Druckes und damit der benötigten Tragfähigkeit der Obermatratze. Die Obermatratze ist damit von weich bis hart stufenlos verstellbar.
Das Körpergewicht der die Obermatratze benützenden Person quetscht beim Belasten der Randzone der Obermatratze die Pumpenkörper (1) und verringert damit deren Volumen. Die sich im Pumpenkörper befindende Luft wird durch die Luftleitungen (7) und die Einwegventile (3) hindurch in das Luftreservoir (2) gepresst und dort komprimiert. Somit sorgt das Körpergewicht der die Obermatratze benützenden Person über das integrierte Luftsystem für stets vorhandenen Luftdruck im Reservoir (2), was Nachfüllung und gleichbleibende Tragfähigkeit des Luftkerns (4) bewirkt. Es braucht für die Nachfüllung des Luftkerns (4) weder Zeit noch gesondert Energie aufgewendet zu werden. Der Luftkern (4) in der Obermatratze wird durch die in Intervallen stattfindenden Belastungen des Systems, allein durch Benützung der Obermatratze stets soweit gefüllt als dies gewünscht, das heisst an der Skala (6) eingestellt ist.When the top mattress is loaded, the body weight of the user creates zone-by-zone pressure. This pressure, which occurs increasingly at the beginning or end of use, particularly in the edge area of the top mattress, presses air out of the integrated pump bodies (1) into the unloaded air reservoir (2). The two one-way valves (3) cause the air to flow in only one direction at a time. The air displaced from the pump bodies (1) is compressed in the air reservoir (2) and serves as a reserve. This compressed air reserve balances the pressure in the air core (4) up to the value that was set on the pressure regulating valve (5) using the scale (6). This compensation takes place at the latest when the top mattress is relieved. If the edge zone is relieved, the pump bodies (1) suck ambient air through the one valve by returning to their starting position. The pump is now ready for further air supply. The adjustable pressure regulating valve (5) together with the air compressed in the air reservoir (2) ensures precisely metered replenishment in the air core (4). The scale (6) allows precise setting of the desired pressure and thus the required load capacity of the top mattress. The top mattress is thus infinitely adjustable from soft to hard.
The body weight of the person using the top mattress squeezes the pump body (1) when the edge zone of the top mattress is loaded, thereby reducing its volume. The air in the pump body is pressed through the air lines (7) and the one-way valves (3) into the air reservoir (2) and compressed there. The body weight of the person using the top mattress ensures that the air pressure in the reservoir (2) is always present via the integrated air system, which results in refilling and constant load-bearing capacity of the air core (4). There is no need for time or energy to refill the air core (4). The air core (4) in the top mattress is always filled as far as desired by the loads on the system that occur at intervals, simply by using the top mattress, i.e. it is set on the scale (6).

Mit Luftkernen (4) ausgestattete Obermatratzen passen sich auch der sie tragenden Unterlage weitgehend an. Durch Verwendung verstellbarer Untermatratzen sind Kopf und Fusshochlagerungen oder Sitzpositionen ohne weiteres möglich.Upper mattresses equipped with air cores (4) also fit largely on the supporting document. By using adjustable bottom mattresses are head and foot elevations or sitting positions possible without further ado.

Das anpassungsfähige und körperfreundliche Luftpolster eignet sich dank der stufenlosen Einstellbarkeit von weich bis hart für den Normalverbraucher als auch für therapeutische Zwecke. Der Antidekubituseffekt wird bei langanhaltender Bettlägerigkeit sehr geschätzt. Es können aber auch andere in der therapeutischen Anwendung gewünschte Effekte erreicht werden. Es können zum Beispiel mehrere Luftkammern mit den entsprechenden Druckregulierventilen verwendet werden. Es sind für therapeutische Anwendungen auch spezielle Bauarten der Luftkerne (4) denkbar. Matratzen (Polster) für Sitzmöbel sind in einer Weiterentwicklung realisierbar. Damit bietet der Einsatz solcher Betten/Polster welche sich bei Benützung mit Luft selbsttätig nachfüllen auch in therapeutischem Bereich willkommene Ergänzung oder Ablösung bisheriger Möglichkeiten.The adaptable and body-friendly air cushion is suitable thanks to the infinitely variable adjustability from soft to hard for the normal consumer as well as for therapeutic purposes. Of the Anti-decubitus effect becomes with long-lasting bedriddenness very appreciated. But there can also be others in the desired therapeutic effects can be achieved. It can, for example, several air chambers with the corresponding Pressure regulating valves are used. It is for therapeutic applications also special types of air cores (4) conceivable. Mattresses (cushions) for seating are in one Further development possible. The use of such offers Beds / upholstery which automatically use air refill also welcome addition in the therapeutic area or replacing previous options.

Die Pumpenkörper (1) wie auch das Reservoir (2) werden gefertigt aus luftdichter Folie (12). Die an geigneter Stelle eingeschweissten Schlauchenden (19) erlauben die Aufnahme der Schlauchverbinder für die Luftschläuche (7). Die schlauchförmig gefertigen Pumpenkörper (1) werden mit aus dem Rahmen (9) geschnittenen, luftdurchlässigen Schaumstoff gefüllt. Das garantiert ein gutes Luftvolumen sowie einwandfreies Rückstellvermögen der Pumpenkörper (1) auch nach jahrelangem Gebrauch. Die Einwegventile (3) werden so eingesetzt, dass Luft stets nur in einer Richtung fliessen kann. Dies garantiert das perfekte funktionieren des Pumpvorganges. Die für den Luftkern (4) verwendete luftdichte Folie (12) wird mit einer dünnen Schicht Schaumstoff (13) flammlaminiert. Dadurch werden Folie und Schaumstoff homogen verbunden. Nach der Fertigung des Luftkerns (4) wird eine Lage Baumwollfrotté (14) aufgebracht. Dieses Verfahren verunmöglicht das entstehen von Kondenswasser in der Obermatratze auch bei grösseren Temperaturunterschieden, verursacht beispielsweise durch Wärmeflasche oder Heizkissen im Bett. Die sich mit Abstand gegenüber liegenden Folien (12) des Luftkerns (4) werden durch querlaufende Verbindungsstege (8) verbunden. Die Stege sind so konstruiert, dass Luft durch Freiräume (24) in genügender Menge durchfliessen kann (Geräuschvermeidung). Durch geschickte Formgebung der Luftkerne werden verschieden harte Zonen geschaffen. So sind zum Beispiel die Zwischenstege (8) in einem Luftkern für eine Obermatratze wie sie in Betten verwendet werden, nicht in stets gleichem Abstand angebracht. Ein vergrösserter Abstand im Mittelbereich des Luftkerns bringt automatisch mehr Volumen und damit grössere Tragfähigkeit. (Mittelzonenverstärkung). Bei Luftsystemen für Sitzpolster (vorgesehene Weiterentwicklung) wird der gewünschte Effekt, das heisst, zumehmende Tragfähigkeit im vorderen Drittel des Sitzes und mehr Widerstand im Kreuzbereich der Rücklehne durch geeignete Formgebung der Luftkerne mühelos erreicht.The pump body (1) and the reservoir (2) are manufactured made of airtight film (12). The welded in a suitable place Hose ends (19) allow the admission of the Hose connector for the air hoses (7). The tubular finished pump body (1) are also from the frame (9) cut, breathable foam filled. The guarantees a good air volume as well as perfect Resilience of the pump body (1) even after many years Use. The one-way valves (3) are used so that air can only flow in one direction. This guarantees that perfect functioning of the pumping process. The one for the air core (4) airtight film (12) is used with a thin Layer of foam (13) flame-laminated. This will be slide and foam connected homogeneously. After manufacturing the A layer of cotton terry cloth (14) is applied to the air core (4). This process prevents the formation of condensation in the top mattress even with larger temperature differences, caused for example by hot water bottle or heating pad in the Bed. The oppositely lying foils (12) of the Air core (4) through transverse connecting webs (8) connected. The webs are designed so that air can pass through A sufficient amount of free space (24) can flow through (noise avoidance). By cleverly shaping the air cores zones of different hardness created. For example, they are Intermediate webs (8) in an air core for a top mattress like this used in beds, not always at the same distance appropriate. An enlarged distance in the middle of the Air core automatically brings more volume and thus larger Load capacity. (Middle zone reinforcement). For air systems for Seat cushion (planned further development) will be the desired one Effect, that is, increasing load-bearing capacity in the front third of the seat and more resistance in the cross area of the backrest easily achieved by suitable shaping of the air cores.

Das Druckregulierventil (5) ist stufenlos einstellbar im Bereich von 0 bis 6o Millibar. Die angebrachte Skala (6) erlaubt eine genaue und stufenlose Einstellung des Luftdruckes im Luftkern (4) und damit der Tragfähigkeit der Obermatratze. The pressure regulating valve (5) is infinitely adjustable in the range from 0 to 60 millibars. The attached scale (6) allows one precise and continuous adjustment of the air pressure in the air core (4) and thus the load capacity of the top mattress.

Bei Verwendung von mehreren Druckregulierventilen und Luftkernen können bei Matratzen oder Sitzpolstern individuell einstellbare Zonen geschaffen worden. Das heisst, es kann zum Beispiel die Festigkeit das Sitzes und dar Rücklehne einzeln reguliert werden.When using multiple pressure regulating valves and air cores can be individually adjusted for mattresses or seat cushions Zones have been created. That means it can, for example Strength of the seat and the backrest individually regulated will.

Der als tragendes Element konstruierte offenzellige und damit luftdurchlässige Schaumstoffrahmen (9) verleiht der Obermatratze die nötige Seitenstabilität. In diesen Rahmen werden die Komponenten der Luftspeisung eingebaut. Bei Uebereinanderlegen von mehreren Pumpenkörpern (1) wird die Effizienz der Lufstpeisung enorm erhöht. Als Füllung für die Pumpenkörper (1) wie auch das Reservoirs (2) werden die für die Aufnahme der Pumpenkörper (1) aus dem Schaumstoffrahmen geschnittenen zylinderförmigen, lufttdurchlässigen Schaumteile verwendet. Der Luftkern (4) wird aus luftdichter Folie (12) gefertigt. Diese wird, bevor sie zur Verarbeitung gelangt, einseitig mit einer dünnen Schicht Schaumstoff (13) flammlaminiert. Diese homogene Verbindung behindert das Verschweissen der Folie in keiner Weise, dient jedoch der Isolation und ermöglicht ein späteres Aufbringen von weiterem Material zum Beispiel Frottéstoff (14) auf den Luftkern (4). Unlaminierte Folie dient für die Zwischenstege (8) des Luftkerns wie auch für den Verbindungsstreifen (24'). Ein an geeigneter Stelle eingeschweisstes Formteil (17) dient als Luft-Ein/Auslass für den Luftkern (4). Nach dem Einschweissen der Zwischenstege (8) sowie der Verbindungsstreifen (24') beendigt das Verschweissen der Ecken die Grundkonstruktion des Luftkerns (4).The open-celled and thus constructed as a load-bearing element air-permeable foam frame (9) gives the top mattress the necessary lateral stability. In this framework, the Components of the air supply installed. When stacking of several pump bodies (1) the efficiency of the Air supply increased enormously. As filling for the pump body (1) as well as the reservoirs (2) are used to hold the Pump body (1) cut out of the foam frame cylindrical, air-permeable foam parts are used. Of the Air core (4) is made of airtight film (12). This is one-sided with a thin layer of foam (13) flame laminated. This homogeneous Connection in no way hinders the welding of the film Wise, however, serves for isolation and enables later Application of further material, for example terry cloth (14) on the air core (4). Unlaminated film is used for the Intermediate webs (8) of the air core as well as for the connecting strip (24 '). A welded in a suitable place Molding (17) serves as an air inlet / outlet for the air core (4). After welding the intermediate webs (8) and the The connecting strip (24 ') ends the welding of the corners the basic construction of the air core (4).

Das Aufbringen von Gewebe, vorzugsweise Frottéstoff (14) auf die Schaumstofflage (13) des Luftkerns (4) verbessert neben der Isolation auch dessen mechanische Festigkeit.The application of fabric, preferably terry cloth (14) to the Foam layer (13) of the air core (4) improves in addition to Isolation also its mechanical strength.
