Abstract

The cushion, mat, mattress or the like has an elastic insert (1), a covering (2; 2', 2"), which surrounds said insert and is made of a material which is impervious to air, and an air closure of the cushion interior. Whilst maintaining the functional advantages of such a cushion, it is to be simplified both in manufacture and in handling. For this purpose, provision is made for the insert (1) to be compressed to a fraction (b) of the thickness (a) which it has in the unstressed state, for the covering (2; 2', 2") to rest essentially on the insert and, without the use of a valve, to form the air closure of the cushion interior merely by its material on all sides. Furthermore, the invention relates to a method of manufacturing such a cushion. <IMAGE>

Description

Die Erfindung betrifft zunächst ein Polster, eine Matte, eine Matratze oder dergleichen (im folgenden kurz "Pol­ster" genannt) gemäß dem Oberbegriff des Anspruches 1. Solche Polster sind im Prinzip beispielsweise aus DE-PS 99773 bekannt. Man kennt sie auch in Form eines soge­nannten Ringkissens. Der luftdichte Abschluß geschieht mit Hilfe eines Ventiles, das in die Umhüllung einge­setzt ist und wahlweise geöffnet oder geschlossen werden kann. Bei geöffnetem Ventil kann man das Polster um einen gewissen Betrag zusammendrücken, wobei der entsprechende Anteil der im Polster befindlichen Luft durch das geöffne­te Ventil herausgepreßt wird. Wird dann das Ventil ge­schlossen so behält das Polster mit der komprimierten Einlage etwa seine Form bei, da einem sich Wiederaus­dehnen der Einlage der dann im Polsterinnern bestehende Luftunterdruck entgegensteht. Funktionell hat sich dieses Polster bewährt. Nachteilig sind die höheren Gestehungs­kosten durch die Herstellung und Einbringung des Ventiles, ferner die Gefahr, daß das Ventil bei unsachgemäßer Hand­habung abreißan, zumindest an seiner Verbindungsstelle mit der Umhüllung einreißen kann (wodurch das Polster aber unbrauchbar werden würde) und schließlich daß ungeschickte Personen, insbesondere durch Alter oder Gebrechen behinderte Personen, mit der Handhabung (Öffnen und Schließen) des Ventiles nicht zurechtkommen können.The invention initially relates to a cushion, mat, mattress or the like (hereinafter referred to as "cushion") according to the preamble of claim 1. Such cushions are known in principle, for example, from DE-PS 99773. They are also known in the form of a so-called ring pillow. The airtight closure takes place with the aid of a valve which is inserted into the casing and can be opened or closed as desired. When the valve is open, the cushion can be compressed by a certain amount, the corresponding portion of the air in the cushion being pressed out by the opened valve. If the valve is then closed, the upholstery with the compressed insert maintains approximately its shape, since a re-expansion of the insert is opposed by the negative air pressure inside the upholstery. This pad has proven itself functionally. Disadvantages are the higher production costs due to the manufacture and introduction of the valve, as well as the risk that the valve will tear off due to improper handling, at least at its connection point the cover can tear (which would make the cushion unusable) and finally that clumsy people, especially people who are disabled due to age or infirmity, cannot cope with the handling (opening and closing) of the valve.

Die Erfindung will ein Polster gemäß dem Oberbegriff des Anspruches 1 so ausbilden, daß bei Beibehaltung seiner funktionellen Vorteile eine Vereinfachung sowohl in der Herstellung, als auch in der Handhabung geschaffen wird.The invention intends to design a cushion according to the preamble of claim 1 in such a way that, while maintaining its functional advantages, simplification is achieved both in manufacture and in handling.

Der Lösung dieser Aufgabe dienen, ausgehend vom Oberbe­griff des Anspruches 1, die Merkmale des Kennzeichens des Anspruches 1. Sämtliche geschilderten Nachteile des vor­bekannten Polsters sind vermieden. Es ist ein Polster mit teilweise komprimierter Einlage geschaffen, die eine relativ harte, in gewissen Grenzun aber noch elastisch nachgiebige Sitzschale bildet. Dies ist in vielen Fällen nicht nur vorteilhaft sondern auch erwünscht, in denen eine lediglich zusammendrückbare Schaumstoffeinlage mit irgendeinem Überzug zu weich und nachgiebig wäre.The solution to this problem, starting from the preamble of claim 1, serve the features of the characterizing part of claim 1. All the disadvantages of the known upholstery described are avoided. A cushion with partially compressed insert is created, which forms a relatively hard, but in certain limits still resilient seat shell. In many cases, this is not only advantageous but also desirable in which a compressible foam insert with any coating would be too soft and compliant.

Die Merkmale des Anspruches 2 beinhalten eine bevorzugte Ausführungsform der Erfindung.The features of claim 2 include a preferred embodiment of the invention.

Eine weitere Ausgestaltungsmöglichkeit der Erfindung ist Gegenstand des Anspruches 3. Hierdurch kann zum einen, so­fern erwünscht, mit einem solchen Polster ein Kühleffekt erreicht werden. Ein weiterer Vorteil besteht darin, daß das spezifische Gewicht eines solchen, teilweise mit einem fließfähigen Medium (z.B. Wasser oder Gel) gefüllten Polster größer ist, so daß es bei Benutzung in einer Bade­wanne nicht so stark aufschwimmt, ggfls. sogar absinkt.A further possible embodiment of the invention is the subject of claim 3. In this way, if desired, a cooling effect can be achieved with such a cushion. Another advantage is that the specific weight of such a pad, partially filled with a flowable medium (eg water or gel), is greater, so that it does not float as strongly when used in a bathtub, if necessary. even drops.

Die Ansprüche 4 und 5 beinhalten Ausgestaltungsmöglich­keiten der Einlage.Claims 4 and 5 contain design options for the insert.

Die Erfindung beinhaltet ferner gemäß Anspruch 6 ein Verfahren zur Herstellung eines solchen Polsters.The invention further includes according to claim 6 a method for producing such a cushion.

Weitere Vorteile und Merkmale der Erfindung sind der nachfolgenden Beschreibung und der zugehörigen Zeich­nung von erfindungsgemäßen Ausführungsmöglichkeiten zu entnehmen. In der Zeichnung zeigt:

  • Fig. 1: im Schnitt gemäß der Linie I-I in Fig. 2 ein Polster nach der Erfindung,
  • Fig. 2: die Draufsicht auf Fig. 1,
  • Fig. 3: das Polster nach Fig. 1, 2 mit einer nicht vollständig ge­schlossenen Umhüllung.
Further advantages and features of the invention can be found in the following description and the associated drawing of possible embodiments according to the invention. The drawing shows:
  • 1: in section along the line II in Fig. 2, a cushion according to the invention,
  • 2: the top view of FIG. 1,
  • Fig. 3: the cushion of Fig. 1, 2 with a not completely closed cover.

Das Polster besteht aus einer teilweise komprimierten elastischen Einlage 1 und einer diese Einlage umgebenden allseitig luftdichten Umhüllung 2, die im wesentlichen an der Einlage anliegt. Dies können zwei Bahnen 2′, 2˝ sein, die entlang ihrer umlaufenden Kanten 2 miteinander luftdicht verbunden, bevorzugt verschweißt sind. Die Herstellung eines solchen Polsters ist sehr einfach. Man nimmt zunächst die nicht komprimierte Einlage 1 (siehe Fig. 3) und umgibt diese mit den beiden Umhüllungshälften 2′, 2˝, wobei eine Seite, z.B. die in Fig. 3 mit 4 be­zifferte und dort rechts gelegene Seite noch nicht luft­dicht abgeschlossen ist. Dann erfolgt die Komprimierung der Einlage 1, z.B. gemäß einer bevorzugten Ausführungs­form der Erfindung um etwa 60 Prozent, und zugleich ein Verschweißen der auf der Seite 4 gelegenen Ränder 3. Damit verringert sich die Dicke der Einlage 1 von dem Betrag a des nicht komprimierten Zustandes und im komprimier­ten Bereich auf den demgegenüber kleineren Betrag b (siehe Fig. 1). Die Einlage dieses Polsters (siehe Fig. 1,2) ist und bleibt entsprechend komprimiert, was auch durch die gegenüber Fig. 3 dichtere Schraffur zeichnerisch angedeu­tet ist. Es bildet eine Art Sitzschale, die relativ fest und widerstandsfähig ist, d.h. nur noch eine geringe Elastizität aufweist. Dabei ist der weitere Vorteil ge­geben, daß die einmal erzielte Formgebung dieser Sitz­schale ohne weiteres durch entsprechenden Druck auf die Oberfläche der oberen Umhüllungshälfte 2′ geändert werden kann. Jedoch ist ein sich Wiederausdehnen der Einlage 1 auf die Dicke a gemäß Fig. 3 nicht möglich, da mit dem Zusammendrücken der Einlage 1 auf die Dicke b gemäß Fig. 1 und die hierdurch bewirkte Verkleinerung des Raumes inner halb der Umhüllung 2′, 2˝ der gesamte Innenraum des Polsters entsprechend verkleinert und außerdem luftdicht abgeschlos­sen ist. Ein sich Wiederausdehnen der Einlage würde zu einer Vergrößerung dieses Innenraumes führen. Dem steht aber der äußere Luftdruck in Verbindung mit dem inneren Unterdruck entgegen. Die gebildete "Sitzschale" bleibt also erhalten und zwar auch dann, wenn keine Person auf diesem Polster sitzt. Andererseits kann die "Sitzschale" aber durch Druck (wie vorstehend erwähnt) in eine andere Form gebracht werden, z.B. wenn sich eine andere Person mit anderen Körperformen auf das Polster setzt. Wenn vor­ stehend beispielsweise vom Sitzen bzw. einer "Sitzschale" gesprochen is, so ist die Erfindung jedoch hierauf nicht beschränkt. So kann z.B. ein Polster nach der Erfindung auch als Matratze ausgebildet sein und dergleichen mehr.The cushion consists of a partially compressed elastic insert 1 and an all-round airtight covering 2 surrounding this insert, which essentially bears against the insert. These can be two webs 2 ', 2˝, which are connected to one another in an airtight manner along their circumferential edges 2, preferably welded. The manufacture of such a cushion is very simple. First, take the non-compressed insert 1 (see Fig. 3) and surround it with the two wrapping halves 2 ', 2˝, one side, for example the numbered 4 in Fig. 3 and the right side there is not yet airtight . Then the compression takes place the insert 1, for example according to a preferred embodiment of the invention by about 60 percent, and at the same time welding the edges 3 on the side 4. The thickness of the insert 1 thus decreases from the amount a of the uncompressed state and in the compressed area the smaller amount b (see Fig. 1). The insert of this cushion (see FIGS. 1, 2) is and remains compressed accordingly, which is also indicated in the drawing by the hatching which is denser than that in FIG. 3. It forms a kind of seat shell, which is relatively firm and resistant, ie only has a low elasticity. There is the further advantage that the shape of this seat shell once achieved can be easily changed by appropriate pressure on the surface of the upper envelope half 2 '. However, a re-expansion of the insert 1 to the thickness a according to FIG. 3 is not possible, since with the compression of the insert 1 to the thickness b according to FIG. 1 and the resulting reduction in the space within the envelope 2 ', 2˝ the entire interior of the upholstery is reduced accordingly and is also airtight. A re-expansion of the insert would lead to an enlargement of this interior. This is countered by the external air pressure in connection with the internal negative pressure. The "seat shell" thus formed is retained even if no person is sitting on this cushion. On the other hand, the "seat shell" can be brought into a different shape by pressure (as mentioned above), for example if another person with different body shapes sits on the cushion. If before standing, for example, sitting or a "seat shell", the invention is not limited to this. For example, a cushion according to the invention can also be designed as a mattress and the like.

Für Sonderfälle, die oben bereits erwähnt wurden, kann das Polsterinnere auch teilweise mit einer Flüssigkeit, bevorzugt Wasser, gefüllt sein (nicht dargestellt). Die allseits luftdichte Umhüllung verhindert ein Austreten der Flüssigkeit.For special cases, which have already been mentioned above, the interior of the cushion can also be partially filled with a liquid, preferably water (not shown). The airtight cover prevents the liquid from escaping.

Die elastische Einlage 1 kann ein elastischer Schaumstoff, aber auch ein anderes elastisch zusammendrückbares Ma­terial, z.B. Gummifasern, sein.The elastic insert 1 can be an elastic foam, but also another elastically compressible material, e.g. Rubber fibers.
