Abstract

The flat upholstery body consists of at least one plate of spring-elastic material with a number of grille webs bounded by apertures at the edges. The grille plate (1) is in the form of an undulating profile body with the wave extremities of its contour with grille webs running through them, preferably with a clearance across the wave extension direction. The wave extremities are formed by wave ridges (5) and wave valleys (6) of a wave contour with equal wavelengths on the upper and lower sides of the profile body. The grille webs running through the wave extremities extend over parts of the wave ridges and wave valleys.

Description

Die Erfindung betrifft einen flächigen Polsterkörper, bestehend aus zumindest einer Gitterplatte aus federelastischem Material mit eine Vielzahl von Gitteröffnungen randseitig begrenzenden Gitterstegen.The invention relates to a flat cushion body consisting of at least one grid plate made of resilient material with a plurality of grid webs delimiting grid openings at the edge.

Bei bekannten derartigen Polsterkörpern (GB-A-307 755), wie sie insbesondere als Sitzpolster und Matratzen verwendet werden, hat die Gitterplatte eine ebene Grundausbildung, und die Polster- oder Federwirkung des Polsterkörpers im Belastungsfall beruht auf einer Druckverformung des federelastischen Materials, in dem bekannten Fall Schaumstoff, vorzugsweise Schaumgummi, im wesentlichen nur in den Kreuzungspunkten, wobei es zu hohen Spitzenspannungen durch Knicken im Schaum kommt, die schnell zu Zerstörung führen.In known such cushion bodies (GB-A-307 755), as they are used in particular as seat cushions and mattresses, the grid plate has a flat basic design, and the cushioning or spring action of the cushion body in the event of a load is based on a compression deformation of the resilient material, in which known case foam, preferably foam rubber, essentially only at the crossing points, with high peak voltages due to kinks in the foam, which quickly lead to destruction.

Der Erfindung liegt die Aufgabe zugrunde, einen flächigen Polsterkörper der eingangs angegebenen Art zu schaffen, der bei einer hervorragenden Belüftung eine verbesserte Federwirkung besitzt und eine lange Lebensdauer hat.The invention has for its object to provide a flat cushion body of the type mentioned, which has an excellent spring action with excellent ventilation and has a long life.

Diese Aufgabe wird nach der Erfindung dadurch gelöst, daß die Gitterplatte als Wellprofilkörper mit die Wellenextrema ihrer Wellenkontur durchlaufenden Gitterstegen ausgebildet ist von denen zumindest ein Großteil quer zu zumindest einer Wellenausbreitungsrichtung voneinander beabstandet sind.This object is achieved according to the invention in that the grid plate is designed as a corrugated profile body with grid webs passing through the wave extremes of its wave contour, at least a large part of which are spaced apart from one another transversely to at least one direction of wave propagation.

Bei dieser Ausgestaltung findet keine, sich für die Lebensdauer des Polsterkörpers als ungünstig erweisende Druckverformung des Polstermaterials im Belastungsfall statt, sondern es erfolgt erfindungsgemäß eine vorgegeben begrenzte Biegeverformung der Gitterplatte aufgrund deren Ausbildung als Wellprofilkörper, bei dem die Gitterstege nach Art von Einzel-Biegefedern weitgehend unabhängig voneinander verformt werden können. Hierdurch besitzt der Polsterkörper nach der Erfindung Federungseigenschaften, die sich durch ein hohes Maß an Punktelastizität auszeichnen. Die Wellenkontur gewährleistet einen günstigen Spannungsverlauf und eine gleichmäßige Aufnahme der Verformungsarbeit im Polstermaterial, was die lange Lebensdauer des Polsterkörpers begünstigt. In this embodiment, there is no compression deformation of the cushioning material, which proves to be unfavorable for the service life of the cushioning body, but rather a predetermined limited bending deformation of the grid plate takes place according to the invention due to its design as a corrugated profile body, in which the grid webs are largely independent in the manner of individual bending springs can be deformed from each other. As a result, the cushion body according to the invention has spring properties which are distinguished by a high degree of point elasticity. The wave contour ensures a favorable stress curve and a uniform absorption of the deformation work in the upholstery material, which favors the long life of the upholstery body.

Für geringe Federwege kann demgemäß eine einzige, nach der Erfindung als Wellprofilkörper ausgebildete Gitterplatte ausreichen, während bei erhöhten Polsterungsanforderungen, z.B. für eine Matratze, der Polsterkörper nach der Erfindung zwei oder mehr solche Gitterplatten in Übereinanderschichtung umfassen kann, wobei die jeweils obere Gitterplatte mit ihren unteren Wellenextrema(Wellenminima)auf den oberen Wellenextrema(Wellenmaxima)der nächstunteren Gitterplatte abgestützt ist.For short spring travel, a single one, according to the Invention designed as a corrugated profile body sufficient grid, while at elevated Upholstery requirements, e.g. for a mattress, the cushion body according to the invention can comprise two or more such grid plates in a layered arrangement, the upper grid plate with its lower wave extremes (wave minima) the upper wave extremes (wave maxima) of the next lower grid plate is supported.

Für lose Übereinanderschichtung, mit dem Vorteil hervorragender Reinigungsfähigkeit auch innerhalb des Polsterkörpers, bieten sich Gitterplatten mit einer Wellenausbreitungsrichtung an, deren Wellenkämme und -täler zum großen Teil von zu ihnen längsverlaufenden Gitterstegen gebildet werden. Die Gitterplatten werden abwechselnd mit zueinander orthogonal verlaufenden Wellenausbreitungsrichtungen übereinandergelegt, so daß sich die in Wellenkämmen und -tälem verlaufenden Gitterstege jeweils paarweise kreuzen. Auch bei der aufgrund der Belastung auftretenden Streckung der Gitterplatten bieten diese so genug Spielraum, sodaß der Abstützungseingriff der Gitterstege immer erhalten bleibt.For loose stacking, with the advantage of excellent cleanability even within the upholstery body, lattice plates with a wave propagation direction offer themselves, the wave crests and valleys of which are largely formed by lattice webs running longitudinally to them. The grid plates are alternately superimposed with directions of wave propagation that are orthogonal to one another, so that the grid webs running in wave crests and troughs each cross in pairs. Even when the grid plates are stretched due to the load, they offer enough leeway so that the support engagement of the grid webs is always retained.

Größere Federhärte ist mit Gitterplatten erreichbar, deren in Abstützungseingriff stehende Gitterstege durch Stoff- oder Formschluß aneinander fixierbar ausgebildet sind. Dabei können Gitterstege punktartige Bereiche in Wellenkämmen und -tälem bilden, die sich bei Übereinanderschichtung paarweise genau gegenüberliegen. Dazu können jedoch auch Gitterplatten verwendet werden, deren Wellenkontur von einer Wellenausbreitung in zwei unterschiedlichen Richtungen geprägt ist. Die dann punktförmigen Wellenextrema werden von Gitterstegen durchlaufen und kommen bei Übereinanderschichtung mehrerer Gitterplatten in Abstützungseingriff, wo sie aneinander fixiert werden.Greater spring hardness can be achieved with grid plates, which are in support engagement standing bars can be fixed to each other by material or form locking are trained. Lattice bars can create point-like areas in wave crests and form valleys that are exactly opposite in pairs when stacked. However, grid plates can also be used for this, the wave contour of wave propagation is shaped in two different directions. The then punctiform wave extremes are traversed by grid webs and come along Stacking several grids in support engagement where they are against each other be fixed.

Für einfache Polsterungen mit geringeren Anforderungen an die Punktelastizität können erfindungsgemäße Polsterplatten auch ohne Abstand der Gitterstege quer zur Wellenausbreitungsrichtung mit Vorteil eingesetzt werden.For simple upholstery with lower demands on the Upholstery panels according to the invention can also have point elasticity without a spacing between the grid bars transverse to the direction of wave propagation can be used with advantage.

Gitterplatten aus vernetzten Elastomeren, wie Naturkautschuk, werden gepreßt und anschließend nachgestanzt. Die Herstellung aus Thermoplasten, wie auch TPE, erfolgt im Spritzgießverfahren oder durch Extrusion und Stanzen. Platten aus Federstahl werden gebogen und gestanzt.Grid plates made of cross-linked elastomers, such as natural rubber, are pressed and then die-cut. The production from thermoplastics, like TPE, is made by injection molding or by extrusion and stamping. plates spring steel is bent and punched.

In Fig. 1 ist als flächiger Polsterkörper eine als Ganzes mit 1 bezeichnete Gitterplatte mit einer in Draufsicht rechteckigen Polsterfläche gezeigt. Die Gitterplatte 1 besteht aus federelastischem Material wie insbesondere elastomerem Material, ggfs. mit Fasereinlagerungen, und umfaßt Gitterstege 2 und 3 in einem sich gleichmäßig wiederholenden Muster, die eine Vielzahl von Gitteröffnungen 4 randseitig umgrenzen.In Fig. 1 is shown as a flat cushion body as a whole with 1 grid plate with a rectangular upholstery surface in plan view. The grid plate 1 consists of resilient material such as, in particular, elastomeric material, possibly with fiber inclusions, and comprises grid webs 2 and 3 in a uniformly repeating pattern which delimit a large number of grid openings 4 on the edge.

Die Gitterplatte 1 ist als Wellprofilkörper mit die Wellenextrema seiner Wellenkontur durchlaufenden Gitterstegen 2 ausgebildet. Die Wellenextrema sind von Wellenkämmen 5 und Wellentälern 6 einer Wellenkontur mit einer Wellenausbreitungsrichtung, konstanter Wandstärke und gleicher Wellenlänge von Oberseite 7 und Unterseite 8 des Wellprofilkörpers gebildet. Die Gitterstege 2 erstrecken sich hierbei jeweils über Teilstücke der Wellenkämme 5 und Wellentäler 6 in deren Längsrichtung. Endseitig münden die Gitterstege 2 unter Bildung jeweils eines Knotenpunktes 17 in die Gitterstege 3 ein, die sich in Wellenausbreitungsrichtung erstrecken. Der gegenseitige, constante, jeweils durchgängig über nahezu eine gesamte Wellenlänge laufende - das heißt verbindungsfreie - Querabstand zwischen benachbarten, sich parallel zueinander über die gesamte Länge der Gitterplatte 1 in Wellenausbreitungsrichtung erstreckenden Gitterstegen 3 definiert hierbei einen Längsabstand zwischen quer zur Wellenausbreitungsrichtung benachbarten Gitterstegen 2, wodurch die versteifende Wirkung der Wellprofil-Form senkrecht zur Wellenausbreitungsrichtung größtenteils wieder aufgehoben und eine hohe Punktelastizität der Gitterplatte 1 erzielt wird. Der Längsabstand zwischen benachbarten Gitterstegen 2 ist gleich dem Quermaß, bezogen auf die Wellenausbreitungsrichtung, der Gitteröffnungen 4.The grid plate 1 is designed as a corrugated profile body with grid webs 2 passing through the wave extremes of its wave contour. The wave extremes are formed by wave crests 5 and wave troughs 6 of a wave contour with a wave propagation direction, constant wall thickness and the same wavelength from top 7 and bottom 8 of the corrugated profile body. The lattice webs 2 each extend over sections of the wave crests 5 and troughs 6 in their longitudinal direction. At the end, the lattice webs 2 open into the lattice webs 3, each forming a node 17, which extend in the direction of wave propagation. The mutual, constant, each running continuously over almost an entire wavelength - that is, connection-free - transverse distance between adjacent, parallel to each other over the entire length of the grating plate 1 in the wave propagation direction 3 defines a longitudinal distance between adjacent grating webs 2 transverse to the direction of wave propagation, whereby the stiffening effect of the corrugated profile shape perpendicular to the direction of wave propagation largely canceled and a high point elasticity of the grid plate 1 is achieved. The longitudinal distance between adjacent grating webs 2 is equal to the transverse dimension, based on the direction of wave propagation, of the grating openings 4.

Das Muster der Gitterstege 2 und 3 bildet, in Draufsicht gesehen, ein in zwei Richtungen rapportmäßiges Muster. Die Rapportlänge bildet das Einfache oder ein ganzes Vielfaches der Wellenlänge. Umgekehrt kann statt dessen die Wellenlänge das Einfache oder ein ganzes Vielfaches der Rapportlänge betragen. Die Rapportlänge und die Wellenlänge sind in beiden Richtungen gleich.The pattern of the bars 2 and 3 forms, seen in plan view, a two-way pattern. The repeat length is the simple thing or a whole multiple of the wavelength. Conversely, the wavelength can be used instead the single or a whole multiple of the repeat length. The repeat length and the wavelength is the same in both directions.

Die die Wellenextrema durchlaufenden Gitterstege 2,3 sind so geformt und angeordnet, daß beim Wenden der Gitterplatte 1 durch Drehung um eine der beiden in ihrer Mittelebene gelegenen Mittelachsen 16 um 180° Wellenminima und Wellenmaxima jeweils wechselseitig, in Draufsicht gesehen, deckungsgleich ineinander übergehen.
Bei Drehung um die zu ihrer Mittelebene orthogonal und zu ihren Außenbereichen mittig verlaufende Achse 19 um 90° oder 270° kommen Wellenmaxima und Wellenminima jeweils wechselseitig paarweise, in Draufsicht gesehen, teilweise zur Deckung.
The lattice webs 2, 3 passing through the wave extremes are shaped and arranged in such a way that when the lattice plate 1 is turned by rotating about one of the two central axes 16 in its central plane 16 by 180 ° wave minima and wave maxima, they alternate with one another, seen in plan view, congruently.
When rotated by 90 ° or 270 ° about the axis 19 running orthogonally to its central plane and centrally to its outer regions, wave maxima and wave minima come to an alternate pair, as seen in plan view, in part.

Wie insbesondere aus den Fig. 2 bis 4 ersichtlich ist, sind die Gitterstege 2 zwischen den benachbarten Gitterstegen 3 jeweils mittig versetzt zueinander angeordnet. Nach einer in der linken Ecke der Fig. 2 veranschaulichten Abwandlung sind die Gitterstege 2 durch Ansätze 9 verlängert, die über den jeweils angrenzenden Gittersteg 3 hinausgeführt und gegeneinander gerichtet sind. Die Ansätze 9 verringern den Längsabstand zwischen zwei Gitterstegen 2, wodurch bei losem Übereinanderlegen mehrerer Gitterplatten 1 mit sich kreuzenden Wellenkämmen 5 und Wellentälern 6 die zulässige Toleranz für ein gegenseitiges Verschieben erhöht wird, in der der Abstützungseingriff zwischen zwei Gitterstegen noch gewährleistet ist und dadurch keine Fixierung der Gitterstege 2 erforderlich ist. Den Ansätzen 9 entsprechen Ansätze 9', die vom Rand 10 der Gitterplatte 1 ausgehen, der, wie auch die übrigen drei Ränder der Gitterplatte 1, von Gitteröffnungen 4 freigehalten ist.As can be seen in particular from FIGS. 2 to 4 , the lattice webs 2 between the adjacent lattice webs 3 are each offset in the center. According to a modification illustrated in the left corner of FIG. 2, the lattice webs 2 are extended by lugs 9, which extend beyond the respectively adjacent lattice web 3 and are directed towards one another. The lugs 9 reduce the longitudinal distance between two crosspieces 2, which, when loosely stacking several crossplates 1 with intersecting wave crests 5 and troughs 6, increases the permissible tolerance for mutual displacement, in which the support engagement between two crosspieces is still guaranteed and therefore no fixation the grid webs 2 is required. The lugs 9 correspond to lugs 9 'which start from the edge 10 of the grid plate 1, which, like the other three edges of the grid plate 1, is kept free from grid openings 4.

Die Dicke der Gitterstege 2, 3 kann auch in Wellenausbreitungsrichtung eine unterschiedliche Bemessung aufweisen. Hierdurch können auch in Wellenausbreitungsrichtung aufeinanderfolgende Zonen unterschiedlicher Federhärte bzw. Biegesteifigkeit der Gitterplatte 1 erzeugt werden. Bei dem in Fig. 5 dargestellten Beispiel ist anhand eines Gittersteges 3 ein erster Bereich A mit einer gegebenen Stegdicke gezeigt, an den sich ein Bereich B mit verkleinerter Stegdicke und entsprechend vergrößerter Wellenamplitude der Wellenkontur anschließt, so daß das Wellenprofil der Gitterplatte 1 ungeachtet solcher Unterschiede in der Stegdicke eine gleichbleibende Gesamthöhe aufweist. Darüberhinaus lassen sich durch unterschiedliche Dicke der Gitterstege 2,3 die Spitzenspannungen reduzieren und die Formänderungsarbeit gleichmäßig verteilen.The thickness of the lattice webs 2, 3 can also have different dimensions in the direction of wave propagation. As a result, successive zones of different spring hardness or bending stiffness of the grid plate 1 can also be produced in the direction of wave propagation. In the example shown in FIG. 5 , a grid area 3 shows a first area A with a given web thickness, to which an area B with a reduced web thickness and a correspondingly increased wave amplitude of the wave contour adjoins, so that the wave profile of the grid plate 1 regardless of such differences has a constant overall height in the web thickness. In addition, the peak voltages can be reduced by varying the thickness of the grid webs 2, 3 and the deformation work can be distributed evenly.

Die Fig. 6 veranschaulicht eine weitere Ausführungsform, bei der die Gitterplatte 1 das gleiche Grundmuster der die Gitteröffnungen 4 begrenzenden Gitterstege 2' und 3 aufweist. Die Wellenkontur der Gitterplatte 1 ist hierbei jedoch von einer Wellenausbreitung in zwei unterschiedlichen Richtungen geprägt, wobei die Gitterstege 2',3 die Wellenextrema jeweils in einem Punkt durchlaufen. Durch diese Wellenkontur mit in zwei unterschiedlichen, und zwar bei dem dargestellten Beispiel rechtwinklig zueinander, horizontal verlaufenden Wellenformen erhält die Gitterplatte 1 eine Ausbildung nach Art eines Eierkartons. Bei Drehung der Gitterplatte 1 um eine ihrer Mittelachsen 16 um 180° gehen Wellenmaxima und Wellenminima, in der Draufsicht gesehen, jeweils ganz bzw. teilweise wechselseitig deckungsgleich ineinander über. 6 illustrates a further embodiment, in which the grid plate 1 has the same basic pattern of the grid webs 2 ′ and 3 delimiting the grid openings 4. However, the wave contour of the grating plate 1 is characterized by wave propagation in two different directions, the grating webs 2 ', 3 each passing through the wave extremes at one point. Due to this wave contour with two different wave shapes that run horizontally to one another in the example shown, the grid plate 1 is designed in the manner of an egg carton. When the grid plate 1 is rotated about one of its central axes 16 by 180 °, wave maxima and wave minima, viewed in plan view, each completely or partially mutually congruent.

Die Knotenpunkte 17 sind in den Bereichen 18 der Wellenextrema so ausgebildet, daß sie dort stoffschlüssig an den jeweils bei Übereinanderschichtung mehrerer Gitterplatten 1 mit ihnen in Abstützungseingriff gelangenden Gitterstegen 2, 3 der benachbarten Gitterplatte 1 fixierbar sind.The nodes 17 are in the areas 18 of the wave extremes designed so that they are cohesive there at the respective layering several grid plates 1 with them in support engagement grid webs 2, 3 of the adjacent grid plate 1 can be fixed.

Fig. 13 zeigt dazu ein ähnliches Ausführungsbeispiel der Erfindung im Detail mit die Wellenextrema durchlaufenden Gitterstegen 2"', 3""'. 13 shows a similar exemplary embodiment of the invention in detail with lattice webs 2 "', 3""' passing through the wave extremes.

Die Fig. 7 veranschaulicht anhand eines Ausschnitts der Gitterplatte 1 in Draufsicht eine Ausbildungsform, bei der die sich über Teillängen der Wellenkämme 5 und Wellentäler 6 erstreckenden Gitterstege 2 unter Bildung von Knotenpunkten 17 endseitig in Gitterstege 3' einmünden, die sich schräg zur Wellenausbreitungsrichtung erstrecken. Alle jeweils quer zur Wellenausbreitungsrichtung benachbarte Gitterstege 2,3' sind in dieser Richtung jeweils durchgängig über nahezu eine gesamte Wellenlänge voneinander beabstandet angeordnet, sodaß sich die Einzel-Biegefedern bildenden Paare von Gitterstegen 3' weitgehend unabhängig voneinander verformen können. Damit ergibt sich eine hohe Punktelastizität der Gitterplatte 1. Die Gitterstege 2 bilden hierbei mit den Gitterstegen 3' beidseits jeweils ein Paar von Gitteröffnungen 4', die in Draufsicht die Grundform gleichschenkeliger Dreiecke aufweisen. Die Paare von Dreiecken bzw. Gitteröffnungen 4' sind in der aus Fig. 7 ersichtlichen Weise in Längsrichtung der Wellenkämme und -täler 5,6 mittig zueinander versetzt und ineinandergeschachtelt angeordnet. FIG. 7 illustrates, on the basis of a section of the grating plate 1, a top view of an embodiment in which the grating webs 2 extending over partial lengths of the wave crests 5 and troughs 6 open at the end into lattice webs 3 ′, which extend obliquely to the direction of wave propagation. All of the grating webs 2, 3 'adjacent to the direction of wave propagation are each spaced apart in this direction continuously over almost an entire wavelength, so that the pairs of grating webs 3' forming the individual spiral springs can largely deform independently of one another. This results in a high point elasticity of the grid plate 1. The grid webs 2 form here with the grid webs 3 'on both sides in each case a pair of grid openings 4', which have the basic shape of isosceles triangles in plan view. The pairs of triangles or lattice openings 4 'are offset in the longitudinal direction of the wave crests and valleys 5, 6 from one another in the manner shown in FIG. 7 and are nested one inside the other.

Der Längsabstand zwischen den in Längsrichtung der Wellenkämme und -täler verlaufenden Gitterstegen 2 ist bei diesem Ausführungsbeispiel von vergleichsweise schmalen Öffnungsspalten 11 zwischen den einzelnen Stegen 2 gebildet. Gegenüber den vergleichsweise großen Abständen zwischen den in Längsrichtung der Wellenextrema aufeinanderfolgenden Gitterstegen 2, wie sie bei dem Ausführungsbeispiel nach den Fig. 1 bis 4 durch das Quermaß der Gitteröffnungen 4 definiert sind, bietet die Ausgestaltung der Gitterplatte 1 nach Fig. 7 eine maximale Toleranz gegenüber Verschiebungen zweier übereinanderliegender Gitterplatten 1. Durch insgesamt längere Steglängen reagiert diese Ausführungsform weicher. Beim Wenden der Gitterplatte 1 um eine ihrer Mittelachsen 16 gehen Wellenminima und Wellenmaxima jeweils wechselseitig, in Draufsicht gesehen, vollständig deckungsgleich ineinander über.The longitudinal distance between the in the longitudinal direction of the wave crests and valleys extending webs 2 is in this embodiment of comparatively narrow opening gaps 11 formed between the individual webs 2. Compared to the comparatively large distances between those in the longitudinal direction the wave extremes of successive webs 2, as in the embodiment 1 to 4 are defined by the transverse dimension of the grid openings 4, the design of the grid plate 1 according to FIG. 7 offers a maximum tolerance towards Displacements of two superimposed grid plates 1. By a total longer web lengths this embodiment reacts softer. When turning the grid plate 1 wave minima and wave maxima each go around one of their central axes 16 mutually, seen in plan view, completely congruent with each other.

Der Polsterkörper gemäß Fig. 8 ist von einem als Ganzes mit 12 bezeichneten Schichtenaufbau mehrerer Gitterplatten 1 gebildet, von denen die Gitterausbildung der oberen Gitterplatte 1, die derjenigen nach den Fig. 1 bis 4 entspricht, durch Wegbrechen eines Eckbereichs einer oberen ebenen Abdeckplatte 13 sichtbar gemacht ist.
Gegenüber der Darstellung in Fig. 1 ist die obere, bei dem dargestellten Beispiel gleichseitige Gitterplatte 1 jedoch um 90° um eine Hochachse gedreht dargestellt. Bei dem dargestellten Beispiel mit insgesamt fünf übereinandergeschichteten quadratischen Gitterplatten 1 ist die jeweils obere Gitterplatte 1 mit ihren unteren Wellenextrema, den in Längsrichtung der Wellentäler 6 verlaufenden Gitterstegen 2, auf den oberen Wellenextrema, den in Längsrichtung der Wellenkämme 5 verlaufenden Gitterstegen 2, der nächstunteren Gitterplatte 1 einander mittig kreuzend abgestützt, wie dies insbesondere aus den Fig. 2 bis 4 ersichtlich ist. Die vorgegebene gegenseitige Lage der einzelnen Gitterplatten 1 kann durch randseitige gegenseitige Fixierung, wie es durch die randseitigen Befestigungspunkte 14 veranschaulicht ist, über Stoff- oder Formschluß aufrechterhalten werden.
8 is formed by a layer structure of a plurality of grid plates 1, designated as a whole by 12, of which the grid formation of the upper grid plate 1, which corresponds to that according to FIGS. 1 to 4, is visible by breaking away a corner region of an upper flat cover plate 13 is made.
Compared to the illustration in FIG. 1, the upper grid plate 1, which in the example shown is equilateral, is shown rotated by 90 ° about a vertical axis. In the example shown with a total of five stacked square grid plates 1, the upper grid plate 1 with its lower wave extremes, the grid webs 2 running in the longitudinal direction of the wave troughs 6, on the upper wave extremes, the grid webs 2 running in the longitudinal direction of the wave crests 5, is the next lower grid plate 1 supported each other in the middle, as can be seen in particular from FIGS. 2 to 4. The predetermined mutual position of the individual lattice panels 1 can be maintained by mutual mutual fixation, as illustrated by the edge-side fastening points 14, via material or form-fitting.

Zur Erzielung dieser gegenseitigen Abstützung der Gitterplatten 1 im Schichtenaufbau an den Wellenextrema ist das Muster der Gitterstege 2, 3, in Draufsicht gesehen, so gewählt, daß bei Spiegelung an einer in der Draufsichtsebene gelegenen, das Muster halbierenden Achse 15 (Fig. 2) die die Wellenextrema durchlaufenden Gitterstege 2 sich kreuzend, und zwar bei dem dargestellten Beispiel mittig, übereinanderliegen. Die Achse 15 ist hier die Winkelhalbierende durch einen Eckpunkt.To achieve this mutual support of the grid plates 1 in the layer structure at the wave extremes is the pattern of the lattice webs 2, 3, in Top view seen, chosen so that when mirroring on one in the top view plane located, the pattern bisecting axis 15 (Fig. 2) passing through the wave extremes Crossbars 2 intersecting, in the example shown in the middle, lie on top of each other. The axis 15 here is the bisector through a corner point.

Sofern der Polsterkörper eine Polsterfläche hat, die in Draufsicht eine Außenform darbietet, die gegenüber einer Drehung um zumindest einen bestimmten Winkel - von z.B. 90° bei einem Quadrat - invariant ist, kann die Übereinanderschichtung einzelner Gitterplatten 1 mit nur einer Wellenausbreitungsrichtung zu einem Polsterkörper mit einer einzigen, identischen Form der Gitterplatte 1 durch dazu abgestimmte Musterwahl und -versatz zum Rand herbeigeführt werden. Solche Formen sind z.B. ein Kreis oder ein gleichseitiges Polygon. In anderen Fällen, insbesondere bei einer in Draufsicht rechteckigen Gitterplatte 1 mit einem Paar langer und einem Paar kurzer Seitenränder, sind zur Bildung eines Polsterkörpers mit mehreren übereinander geschichteten Gitterplatten 1 entsprechend Fig. 8 zwei verschiedene Formen der Gitterplatte 1 erforderlich, bei denen die Wellenausbreitungsrichtungen rechtwinklig zueinander verlaufen können.If the upholstery body has an upholstery surface which, when viewed from above, has an outer shape which is invariant with respect to rotation by at least a certain angle - for example 90 ° for a square - the stacking of individual grating plates 1 with only one direction of wave propagation can result in an upholstery body with one single, identical shape of the grid plate 1 can be brought about by coordinated pattern selection and offset to the edge. Such shapes are, for example, a circle or an equilateral polygon. In other cases, in particular in the case of a grid plate 1 which is rectangular in plan view and has a pair of long and a pair of short side edges, two different forms of the grid plate 1 are required to form a cushion body with a plurality of stacked grid plates 1 according to FIG. 8, in which the wave propagation directions are at right angles can run to each other.

Bei Gitterplatten 1 mit zwei Wellenausbreitungsrichtungen und/oder punktförmiger Ausbildung der Wellenextrema ist bei entsprechender Musterwahl und -versatz zum Rand auch in diesen Fällen eine Übereinanderschichtung identischer Gitterplatten 1 möglich.For grating plates 1 with two directions of wave propagation and / or point-shaped formation of the wave extremes is with appropriate choice of pattern and offset to the edge, even in these cases, an identical layering Grid plates 1 possible.

In den Fig. 9 und 10 sind zwei Ausführungsbeispiele einer Gitterplatte 1 mit einer Wellenausbreitungsrichtung und gegenüber den vorhergehenden Ausführungsbeispielen bogenförmigen Gitterstegen 3" bzw. 3"' dargestellt.
Die bei der Belastung der Gitterplatte 1 aufgrund des Flachlegens des Wellenprofils auftretende Streckung in Wellenausbreitungsrichtung wird durch Stauchen der sich in Wellenausbreitungsrichtung erstreckenden, bogenförmigen Gitterstege 3" bzw. 3"' wieder ausgeglichen, sodaß die Verschiebung zweier übereinanderliegender Gitterplatten 1 gegeneinander verringert wird. Dies erlaubt die Realisierung größerer Wellenamplituden mit größerer Steifheit und größerem Federweg und damit höhere Polsterkörper bei gleicher Anzahl von Gitterplatten 1, was zu einer Verringerung der Gesamtkosten führt. Die Federwirkung wird durch bogenförmige Gitterstege 3" bzw. 3"' weicher aufgrund der vergrößerten Länge der von den Gitterstegen 3" bzw. 3"' gebildeten Biegefedern.
9 and 10 show two exemplary embodiments of a grid plate 1 with a wave propagation direction and, compared to the previous exemplary embodiments, curved grid webs 3 "and 3"', respectively.
The stretching in the direction of wave propagation which occurs when the grating plate 1 is loaded due to the wave profile being laid flat is compensated for by upsetting the arc-shaped grating webs 3 "or 3"'extending in the direction of wave propagation, so that the displacement of two grating plates 1 lying one above the other is reduced. This allows the realization of larger wave amplitudes with greater rigidity and greater spring travel and thus higher cushion bodies with the same number of grid plates 1, which leads to a reduction in the total costs. The spring action is softer due to the arcuate lattice webs 3 "or 3"'due to the increased length of the spiral springs formed by the lattice webs 3 "or 3"'.

Die Fig. 11 und 12 zeigen zwei Ausführungsbeispiele einer Gitterplatte 1 nach der Erfindung, die ursprünglich aus Wellprofil-Platten mit einer Wellenausbreitungsrichtung erzeugbar sind, nach Einbringen des Gittermusters unter punktförmiger Ausbildung der Wellenextrema jedoch mehrere Wellenausbreitungsrichtungen - in Fig. 11 drei, in Fig. 12 vier - erkennen lassen. 11 and 12 show two exemplary embodiments of a grating plate 1 according to the invention, which can originally be produced from corrugated profile plates with a wave propagation direction, but after introducing the grating pattern with punctiform formation of the wave extremes, several wave propagation directions - in FIG. 11 three, in FIG. 12 four - show.

Die Gitterstege 2" und 3"" bzw. 2"' und 3""' bilden Knotenpunkte 17 , in denen sie sich orthogonal kreuzen. Alle jeweils quer zur Wellenausbreitungsrichtung - das heißt hier in Richtung der ursprünglichen Wellenkämme 5 und Wellentäler 6 - zueinander Benachbarte der Gitterstege 2" und 3"" bzw. 2"' und 3""' sind quer zur Wellenausbreitungsrichtung jeweils durchgängig über nahezu eine gesamte Wellenlänge voneinander beabstandet angeordnet, wobei in diesen Ausführungsbeispielen ihre Abstände in dieser Richtung nicht - wie im Ausführungsbeispiel nach Fig. 1 bis 6 - über eine Wellenlänge constant, sondern entsprechend der Ausformung der Gitterstege 2" und 3"" bzw. 2"' und 3""' unterschiedlich sind.The grid bars 2 "and 3" "or 2" 'and 3 ""' form nodes 17 in which they cross orthogonally. All of them transverse to the direction of wave propagation - that means here in the direction of the original wave crests 5 and wave troughs 6 - Adjacent to each other the bars 2 "and 3" "or 2" 'and 3 ""' are transverse to Wave propagation direction consistently over almost an entire wavelength spaced from each other, their in these embodiments Distances in this direction are not - as in the exemplary embodiment according to FIGS. 1 to 6 a wavelength constant, but according to the shape of the grid bars 2 " and 3 "" or 2 "'and 3" "' are different.

Beim Durchlaufen eines Wellenextremums bilden die Gitterstege 2", 3"" bzw. 2"', 3""' im Bereich 18 kreisförmige Verbreiterungen, an denen sie bei Übereinanderschichtung zweier oder mehrerer Gitterplatten 1 in Abstützungseingriff kommen und stoffschlüssig an den jeweils mit ihnen in Abstützungseingriff gelangenden Gitterstegen 2", 3"" bzw. 2"', 3""' der benachbarten Gitterplatten 1 durch zum Beispiel Klebstoff oder Schweißen stoffschlüssig fixierbar sind.The grid webs form when passing through an extreme wave 2 ", 3" "or 2" ', 3 ""' in the area 18 circular widenings on which they are stacked two or more grid plates 1 come into support engagement and cohesively on the lattice webs that come into support engagement with them 2 ", 3" "or 2" ', 3 ""' of the adjacent grid plates 1 by, for example, adhesive or welding can be firmly fixed.

Bei Drehung der Gitterplatte 1 um die zu ihrer Mittelebene orthogonal und zu ihren Außenrändem mittig verlaufenden Achse 19 um 90 oder 270° kommen Wellenmaxima und Wellenminima jeweils paarweise, in Draufsicht gesehen, zur Deckung, wodurch sie bei Übereinanderschichten zweier identischer, in dieser Weise zueinander gedrehter Gitterplatten 1 im Ausführungsbeispiel gemäß Fig. 12 alle, gemäß Fig. 11 zu etwa 50% wechselseitig paarweise in Abstützungseingriff gelangen. Upon rotation of the grid plate 1 about the orthogonal to its central plane and to their outer edges of the central axis 19 by 90 or 270 ° wave maxima and wave minima come in pairs, seen in plan view, to cover, which means that when two identical layers are stacked on top of one another 12 rotated relative to each other in the embodiment of FIG. 12, According to FIG. 11, approximately 50% alternately come into support engagement in pairs.

In Fig. 11 liegen die Knotenpunkte 17 jeweils zwischen den Bereichen 18. Das Muster der Gitterstege 2", 3"" ist so gewählt, daß bei Spiegelung an hier beispielhaft gewählten Mittelachsen 16 der Polsterfläche die Bereiche 18 übereinanderliegen, sodaß ein mehrschichtiger Polsterkörper mit nur einer Gitterplatte 1 realisierbar ist, indem diese Gitterplatte 1 in der jeweils folgenden Lage um die Mittelachse 16 um 180° gewendet wird, wodurch die Wellentäler 6 der oberen Gitterplatte 1 mit den Wellenkämmen 5 der unteren Gitterplatte 1 in ihren Bereichen 18 in Abstützungseingriff kommen und dort aneinander fixiert werden können.In Fig. 11 , the nodes 17 each lie between the areas 18. The pattern of the lattice webs 2 ", 3""is chosen so that when mirroring at the central axes 16 of the upholstered surface chosen here as an example, the areas 18 lie one above the other, so that a multi-layered upholstered body with only a grid plate 1 can be realized by turning this grid plate 1 in the following position around the central axis 16 by 180 °, as a result of which the troughs 6 of the upper grid plate 1 come into support engagement with the wave crests 5 of the lower grid plate 1 in their areas 18 and there can be fixed to each other.

In Fig. 12 sind die Knotenpunkte 17 in Bereichen 18 der Wellenkämme 5 bzw. Wellentäler 6 angeordnet. Dort sind sie bei Übereinanderschichtung zweier oder mehrerer Gitterplatten 1 stoffschlüssig an dem jeweils mit ihnen in Abstützungseingriff gelangenden Gittersteg 2"', 3""' der benachbarten Gitterplatte 1 fixierbar. 12 , the nodes 17 are arranged in areas 18 of the wave crests 5 or wave troughs 6. There, when two or more grid plates 1 are layered one on top of the other, they can be fixed cohesively to the grid web 2 "', 3""' of the neighboring grid plate 1 that comes into support engagement with them.

Beispielhaft sind wieder zwei Mittelachsen 16 zweier möglicher den Ausschnitt der Fig. 12 bildender Gitterplatten 1 markiert. Bei Spiegelung an diesen Mittelachsen 16 sind die Bereiche 18 deckungsgleich, wodurch entsprechend Fig. 11 beim Wenden einer Gitterplatte 1 durch Drehung um eine Mittelachse 16 um 180° die Bereiche 18 der Wellenkämme 5 der unteren Gitterplatte 1 mit den Bereichen 18 der Wellentäler 6 der oberen Gitterplatte 1 in Abstützungseingriff gelangen und stoffschlüssig aneinander fixierbar sind.Two central axes 16 of two possible are again exemplary the section of FIG. 12 forming grid plates 1 marked. When mirroring on this The central axes 16 are congruent with the areas 18, so that according to FIG. 11 when turning a grid plate 1 by rotating about a central axis 16 by 180 ° Areas 18 of the wave crests 5 of the lower grid plate 1 with the areas 18 of the Troughs 6 of the upper grid plate 1 come into support engagement and cohesively are fixable to each other.

Die bogenförmigen Gitterstege 2"', 3""' verringern die Ausdehnung der Gitterplatte 1 bei Belastung durch Flachlegen ihrer Wellenkontur, indem sie über Verringerung des Bogenradius durch Biegen gestaucht werden.The arcuate lattice webs 2 "', 3" "' reduce the expansion the grid plate 1 when loaded by flattening its wave contour by can be compressed by bending to reduce the radius of the arc.

Die Gitterstege 2"', 3""' durchlaufen die Wellenextrema, indem sie endseitig unter Bildung eines Knotenpunktes 17 ineinander einmünden. Ihr Endpunkt ist jeweils vier Gitterstegen 2"',3""' gemeinsam und ist gleichzeitig der in einem Wellenextremum angeordnete Knotenpunkt 17.The bars 2 "', 3" "' pass through the wave extremes by they open into one another at the end to form a node 17. Your end point is four grid bars 2 "', 3" "' in common and is at the same time in a wave extreme arranged node 17.

Während Fig. 13 eine Verbindung zweier Gitterplatten 1 in ihren einander gegenüberliegenden Bereichen 18 durch Stoffschluß zeigt, zeigt Fig. 14 eine Fixierung durch Formschluß. Die Wellenkontur wird aus einem trapezförmigen Polygonzug gebildet, dessen Eckpunkte jeweils in den Wellenextrema angeordnet sind. Die Stege 2"',3""' der Gitterplatten 1 sind geradlinig und gehen zum Wellental 6 in einen Knotenpunkt 17 über, der mittig mit einem konischen Durchgangsloch im Bereich 18 des Wellentales 6 versehen ist. Die anderen Enden der Gitterstege 3""' gehen ebenfalls in Knotenpunkte 17 über, die einen nach oben konisch auslaufenden Zapfen 20 bilden, der im Bereich 18 der Wellenkämme 5 angeordnet ist. While FIG. 13 shows a connection of two grid plates 1 in their mutually opposite regions 18 by means of material locking, FIG. 14 shows a fixation by means of positive locking. The wave contour is formed from a trapezoidal polygon whose corner points are arranged in the wave extremes. The webs 2 "', 3""' of the grid plates 1 are rectilinear and go to the wave trough 6 at a node 17, which is provided in the center with a conical through hole in the area 18 of the wave trough 6. The other ends of the grid bars 3""' likewise merge into nodes 17, which form an upwardly tapering pin 20 which is arranged in the region 18 of the shaft ridges 5.

Die untere Gitterplatte 1 ist gegenüber der oberen um eine vertikale Achse 19 (Fig. 12) um 90° gedreht. Das Muster der Gitterstege 2"', 3""' ist so ausgebildet, daß bei dieser Drehung die nach oben stehenden konischen Zapfen 20 der Bereiche 18 in den Wellenkämmen 5 mit den Durchgangslöchern der Bereiche 18 in den Wellentälern 6 in Abstützungseingriff gelangen, wobei der Konus der Durchgangslöcher zweistufig ausgebildet ist. Der erste Bereich dient zum Einfädeln des konischen Zapfens 20 bis zum Fluchten ihrer beiden Mittelachsen. Der zweite Bereich dient zum paßgenauen Abstützungseingriff beider, sodaß sich beide bei Belastung des Polsterkörpers zentrieren und ineinander verkeilt werden, sodaß ein um Reibkräfte verstärkter Formschluß entsteht.The lower grid plate 1 is vertical to the upper one Axis 19 (Fig. 12) rotated by 90 °. The pattern of the webs 2 "', 3" "' is designed that with this rotation the upstanding conical pin 20 of the areas 18 in the wave crests 5 with the through holes of the areas 18 in the Valleys 6 come into support engagement, the cone of the through holes is designed in two stages. The first area is used to thread the conical spigot 20 until the alignment of their two central axes. The second area is used for a perfect fit Support engagement of both, so that both are when the cushion body is loaded center and be wedged into each other, so that a positive engagement increased by frictional forces arises.

In den Fig. 15 und 16 ist ein weiteres Ausführungsbeispiel einer erfindungsgemäßen Gitterplatte 1 mit einer Wellenausbreitungsrichtung aber punktförmiger Ausbildung der Wellenextrema gezeigt. Die Wellenmaxima werden von Zapfen 20',20", die Wellenminima von kegelförmigen Membranen 21 mit gegenüber den Gitterstegen 2"',3""' geringerer Dicke gebildet, die mit einem Schlitz 22 versehen sind. 15 and 16 show a further exemplary embodiment of a grating plate 1 according to the invention with a wave propagation direction but a punctiform design of the wave extremes. The wave maxima are formed by pins 20 ', 20 ", the wave minima by conical membranes 21 with a smaller thickness than the lattice webs 2"', 3 ""', which are provided with a slot 22.

Beim Übereinanderschichten zweier Gitterplatten 1 wölbt der Zapfen 20',20" die Membran 21 im Bereich des Schlitzes 22 nach oben, wodurch die Schlitzbreite bis auf die Zapfendicke vergrößert wird und der Zapfen 20',20" vom Schlitz 22 aufgenommen und dort verkeilt wird. Es kommt zur Anlage des ringförmigen Knotenpunktes 17 des Wellenminimums der oberen Gitterplatte 1 auf den Gitterstegen 2"',3""' der unteren Gitterplatte 1. Beide Gitterplatten 1 sind gegenüber Verschiebung in der Gitterplattenebene aneinander fixiert. Bei Auftreten von vertikalen Zugkräften, die zum Trennen beider Gitterplatten 1 führen könnten, nimmt der Zapfen 20',20" den Innenrand des Schlitzes 22 aufgrund der hohen Reibwerte von Elastomeren mit, was aufgrund der Geometrie zu einem noch stärkeren Verkeilen beider führt.When two lattice panels 1 are stacked on top of one another, the Pin 20 ', 20 "the membrane 21 in the area of the slot 22 upwards, thereby the Slot width is increased to the pin thickness and the pin 20 ', 20 "from the slot 22 is picked up and wedged there. The ring-shaped node is created 17 of the wave minimum of the upper grid plate 1 on the grid webs 2 "', 3" "' of the lower grid plate 1. Both grid plates 1 are in relation to displacement in the grid plate level fixed to each other. When vertical tensile forces occur, the could lead to separation of both grid plates 1, the pin 20 ', 20 "takes the inner edge of the slot 22 due to the high coefficients of friction of elastomers with what due the geometry leads to an even stronger wedging of both.

Durch Ausformen eines Hinterschnitts am Zapfen 20" kann ein Abstützungseingriff mit reinem Formschluß sowohl in vertikaler als auch in horizontaler Richtung erzielt werden, nach Art eines Druckknopfes.By forming an undercut on the pin 20 ", a Support engagement with pure positive locking in both vertical and horizontal Direction can be achieved in the manner of a push button.

Die Wellenkontur bildet keine mathematische Funktion, sondern kehrt S-förmig in Schleifen teilweise wieder zurück. 17 are top 7 and bottom 8, on the other wave crests 5 and troughs 6, i.e. the areas of the wave maxima and wave minima, the corrugated profile grid plate 1 of different wave contours educated. The wave contour does not form a mathematical function, but returns in an S-shape partly back in loops.

In Fig. 18 ist das Wellenprofil punktsymmetrisch zu den Wendepunkten der Profilmittellinie, wodurch Wellenmaxima und Wellenminima gleich ausgeformt sind. In beiden Ausführungsbeispielen differieren die Dicken des Wellprofils auf der Wellenlänge zum Ausgleich von Spannungsspitzen und gleichmäßiger Verteilung der Formänderungsarbeit und sind die Wellenkonturen symmetrisch zu zur Gitterplatten-Mittelebene senkrechten Mittelachsen.In Fig. 18 the wave profile is point symmetrical to the turning points the profile center line, whereby wave maxima and wave minima are shaped equally are. In both exemplary embodiments, the thicknesses of the corrugated profile differ the wavelength to compensate for voltage peaks and even distribution the deformation work and the wave contours are symmetrical to the center plane of the grid plate vertical central axes.

Es ist auch keine stetige Wiederholung gleicher Wellen erforderlich. Die Wellenkontur kann von Welle zu Welle differieren mit unterschiedlichen Amplituden, unterschiedlichen Wellenlängen, unterschiedlichen Wandstärken oder Wandstärkeverläufen und unterschiedlicher Formgebung.Embodiments according to the invention are also effective, the wave contours of which are not perpendicular to the central plane of the grid plate Center axis are formed symmetrically. It is also not a constant repetition of the same Waves required. The wave contour can differ from wave to wave with different Amplitudes, different wavelengths, different wall thicknesses or wall thickness profiles and different shapes.

Für die Anwendung des Polsterkörpers bei Matratzen und Sitzpolstern kommt vorzugsweise eine Wellenamplitude im Bereich von 5 bis 50 mm in Betracht. Hieraus ergibt sich eine Dicke der Gitterstege 2,3; 2',3; 2,3'; 2,3"; 2,3"'; 2",3""; 2"',3""' im Bereich von etwa 0,5 bis 50 mm.In the cushion bodies shown and described so far the total area of the grid openings is 4.4 ', 4' ', 4' '', 4 '' '' or 4 "" 'in plan view of the Grid 1 about 45% to 95% of the total area of grid 1. The thickness of the Bars 2,3; 2 ', 3; 2,3 '; 2.3 "; 2.3" '; 2 ", 3" "; 2" ', 3 ""' can be about 10 to 100% of the wave amplitude the grid plate 1. For the use of the upholstered body on mattresses and seat cushions preferably have a wave amplitude in the range of 5 up to 50 mm.
