Abstract

The invention relates to end cap elements (22) and supporting elements (2, 2', 42) for bed frames and mattress cores. Said elements have segmented, arched, flexible, non-crossing and crossing bridges (1, 11, 21, 31, 41, 51) whose ends can be connected to two adjoining end caps (22), supporting disks (2, 2', 42) or mattress spiral spring end rings (55) each so as to rotate and/or elastically deform. The segmented bridges (1, 11, 21, 31, 41, 51) are produced from permanently flexible plastics or from spring metal wires or strips. The longitudinal centers of the bridges (1, 11, 21, 31, 41, 51) are slidingly supported by or integrated into sliding blocks (5, 15, 25, 35, 45) that are fixed on retaining bolts, cross strips or supporting disks, or by means of spiral wires (54) in a mattress core. These elements, when inserted in bed frames and mattress cores, have a strong, interactive coupling force and a high negative and positive adaptation stroke h > H of the height of the structure, especially in a crossed arrangement of the bridges (1, 11, 21, 31, 41, 51) in pairs and spaced-apart at a defined distance, said bridges sliding under end caps (22) and disks (2, 2', 42). The inventive elements are especially suitable for motorized bed frames with a large head and foot adjustment range and for cross-side rail versions.

Description

Die Erfindung betrifft Endkappen- und Einzelunterstützungs-Elemente für Bettunterrahmen und Matratzenkerne mit segmentierten, bogenförmigen, elastischen Brücken, deren Enden mit je zwei benachbarten Unterstützungs-Elementen verbunden sind, und die um ihre Längsmitten durch fixierte Gleitschuhe gleitend unterstützt sind. Auf diese Weise können sich je nach Belastung die Brückenteile von einem Endkappen- oder Unterstützungs-Element zum anderen verschieben und so eine starke, interaktive Koppelung der Elemente und eine positive Hubanpassung bewirken. Die Brücken sind unter den Endkappen oder Unterstützungs-Tellern in einem Abstand voneinander oder über Kreuz mit an den Enden angeformten Drehachsen oder als solche ausgebildeten Querstegen in Laschen an den Endkappen oder Tellern drehbar gelagert, oder eine elastisch flexible Zone an den Enden der Brücken gewährleisten deren elastische Verform-barkeit und damit die maximale Absenkung.The invention relates to end cap and single support elements for bed underframes and mattress cores having segmented arcuate elastic bridges whose ends are connected to two adjacent support elements and which are slidably supported around their longitudinal centers by fixed sliding shoes. In this way, depending on the load, the bridge parts may shift from one endcap or support element to the other, causing a strong, interactive coupling of the elements and a positive stroke adjustment. The bridges are rotatably mounted under the end caps or support plates at a distance from each other or crosswise formed at the ends with rotary axes or formed as transverse webs in tabs on the end caps or plates, or ensure an elastically flexible zone at the ends of the bridges elastic deformability and thus the maximum reduction.

Bei beiden und besonders bei der Überkreuz-Anordnung wirkt die Interaktion stark progressiv und koppelt mehre als fünf, benachbarte Elemente stark miteinander.In both, and especially in the cross-over arrangement, the interaction is highly progressive and strongly couples more than five neighboring elements.

Die Endkappen- und Unterstützungs- Elemente mit diesen segmentierten, bogenförmigen Brücken weisen in den verschiedenen möglichen Konstruktionen die folgenden vorteilhaften Eigenschaften auf:

  1. 1. Interaktive Zwangskoppelung mehrerer Unterstützungs-Elemente im Bettunterrahmen sowie beim Einsatzt dieser gekopplten Elemente in Matratzenkernen. Sie bietet sehr große Variabilität im Einsatz und der Konfiguration der Brücken, insbesondere in der Kreuzungs- als auch in der beabstandeten Anordnung, bei der drehbaren Befestigung der Brücken- Enden direkt an den Endkappen-und Unterstützungs- Tellern, sowie der Zusammenfassung zu fest beabstandeten, gekreuzten, gleitenden Paaren mit Abstands- Haltern oder auf Gleitschlitten. Alle diese Versionen führen zu einer sich stark fortpflanzenden Kopplung.
  2. 2. Einem Gesamthub h ≥ H, mit H der Bauhöhe des Endkappen- oder Unterstützungs-Elementes, der sich mit h = hneg + hpos aus negativem und positivem Anpassungshub zusammensetzt.
  3. 3. Keine Versteifung beim Absenken durch Segmentierung der Brücken durch drehbare und/oder elastische oder verschieblich bewegliche Anbringung der Brücken an den Endkappen oder Unterstützungs-Tellern. Eine einfache Zonen-Aufteilung, eine Kopf- und Fußverstellung, auch für Motorrahmen, ist durch die Segmentierung der Brücken, ggf. auch durch Kombination von Einzelunterstützungs- und Endkappen-Elementen für Querleisten möglich.
  4. 4. Fertigung der Brücken aus dauerelastischem Kunststoff in einem Spritzguß-Verfahren oder aus Federmetall - Drähten oder -Flachbändern und der Teller in einem Extrudier-Verfahren ist preiswert möglich.
  5. 5. Der Einsatz in Matratzenkernen in der Kombinationen mit Spiralfedern in verschiedenen Versionen ergeben Matratzen mit interaktiver, positiver Hubanpassung.
The endcap and support elements with these segmented arcuate bridges have the following advantageous properties in the various possible constructions:
  1. 1. Interactive forced coupling of several support elements in the bed subframe and the use of these coupled elements in mattress cores. It offers great versatility in use and configuration of the bridges, particularly in the intersection and spaced arrangement, in the rotatable attachment of the bridge ends directly to the endcaps and support plates, as well as the summary to tightly spaced, crossed, sliding pairs with spacers or on sliding slides. All of these versions result in a highly communicative coupling.
  2. 2. A total stroke h ≥ H, where H is the height of the end cap or support element, which is composed of h = h neg + h pos of negative and positive adjustment strokes.
  3. 3. No stiffening when lowering by segmentation of the bridges by rotatable and / or elastic or displaceable movable attachment of the bridges to the end caps or support plates. A simple zone division, a head and foot adjustment, also for motor frames, is possible by the segmentation of the bridges, possibly also by combining individual support and end cap elements for cross bars.
  4. 4. Manufacturing the bridges of permanently elastic plastic in an injection molding process or made of spring metal - wires or flat bands and the plate in an extrusion process is inexpensive.
  5. 5. The use in mattress cores in combinations with coil springs in different versions provide mattresses with interactive, positive Hubanpassung.

Stand der TechnikState of the art

Der Stand der Technik ist in EP 0 793 432 und dem US Patent 5 924 149 beschrieben, in denen verschiedene Endkappen-Elemente als auch Einzelunterstützungs-Elemente aufgeführt sind. Die dort beschriebenen Endkappen werden in dem deutschen Gebrauchsmuster DE 299 02 965 auf Einzelunterstützungs-Elemente und Anwendungen in Matratzenkernen diversifiziert. In dem Gebrauchsmuster DE 20 2004 015 672 und der Patent Anmeldung DE 10 2005 026 013 werden Unterstützungs-Elemente mit steifen, gekreuzten und gleitenden Brücken beschrieben.The state of the art is in EP 0 793 432 and the U.S. Patent 5,924,149 describing various end-cap elements as well as single-support elements. The end caps described therein are in the German utility model DE 299 02 965 diversified to single support elements and mattress core applications. In the utility model DE 20 2004 015 672 and the patent application DE 10 2005 026 013 Support elements are described with stiff, crossed and sliding bridges.

Der Vorteil der hier beschriebenen Erfindung gegenüber der durchgehenden Wellenbandfederung, die in dem US Patent No. 6,647,574 B2 und der PCT Publication WO 01/50924 A1 beschrieben ist, besteht in den Punkten:

  • Die bogenförmigen, elastischen Brücken sind segmentiert und drehbar und/oder elastisch beweglich an beiden Enden an den Unterstützungs-Tellern oder Endkappen angeordnet.
  • So kommt es zu keiner Versteifung beim Absenken mehrerer Unterstützungs-Elemente durch Aufsummieren der Verschiebung mehrerer, gleichzeitig abgesenkter Brücken.
  • Die starke Interaktion wirkt über die nächsten Nachbarn hinaus, auf mindestens fünf Elemente, besonders aktiv und progressiv bei den gekreuzten Brücken.
  • Die Segmentierung der Brücken erlaubt eine einfache Zonen- Variation in Bettunterrahmen.
  • Die Herstellung der Einzel- Brücken ist materialsparend und damit preiswert möglich aus dauerelastischen Kunstoffen in einem Spritzgußverfahren oder aus Stahlbändern und -drähten.
The advantage of the invention described here over the continuous wave band springing, which in the US Pat. 6,647,574 B2 and the PCT Publication WO 01/50924 A1 is described in the points:
  • The arcuate elastic bridges are segmented and rotatably and / or elastically movably disposed at both ends on the support plates or end caps.
  • Thus, there is no stiffening when lowering several support elements by adding up the displacement of several simultaneously lowered bridges.
  • The strong interaction extends beyond the nearest neighbors, to at least five elements, especially active and progressive in the crossed bridges.
  • The segmentation of the bridges allows for easy zone variation in bed subframes.
  • The production of individual bridges is material-saving and thus inexpensive possible from permanently elastic plastic in an injection molding process or steel strips and wires.

Figurenbeschreibungfigure description

In Fig. 1 a, b und (d: dafür gelten die Elemente in Klammern) sind Längs- und Querschnitte gezeigt durch interaktive Doppel-Endkappen- 22 Elemente (Unterstützungs- 2 Element) mit elastischen, bogenförmigen, nicht gekreuzten Brücken 1 (21). Die Brücken- 1 (21) Bänder haben an beiden Enden beidseitig angeformte, runde Drehachsen 3 (einen Drehachsen- Quersteg 13), eingerastet in Einclips-Laschen 4 (14), welche an je zwei benachbarten Endkappen 22 (Unterstützungs- 2 Elementen) angeformt sind.In Fig. 1 a, b and (d: the elements in brackets) are longitudinal and cross sections shown by interactive double-end cap 22 elements (support 2 element) with elastic, arcuate, non-crossed bridges 1 (21) , The bridge 1 (21) bands have on both ends formed on both sides, round rotary axes 3 (a Drehachsen- transverse web 13), engages in Einclips-tabs 4 (14), which on two adjacent end caps 22 (support 2 elements) integrally formed are.

Die Brücken- 1 Bänder aus Kunststoff, Fig. 1 a und b (Brücken 21 aus Rund- oder Flachdraht- Paaren, aus Kunststoff oder Federstahl) sind etwa in ihrer Längsmitte durch Gleitschuhen 25 (15) gleitend unterstützt, die an Seitenholm- 20 festen Haltebolzen 17 integriert sind (mit einem Zwischensockel 26 auf Querleisten 10 befestigt sind, die quer im Bettunterrahmen verlaufen).The bridges 1 bands of plastic, Fig. 1 a and b (bridges 21 of round or flat wire pairs, plastic or spring steel) are approximately slidably supported in their longitudinal center by sliding blocks 25 (15), the fixed to Seitenholm- 20 Retaining bolts 17 are integrated (are fixed with an intermediate base 26 on transverse strips 10 which extend transversely in the bed subframe).

Abgerundete Einclips-Vorrichtungen 6 (16) an den Gleitschuhen 25 (15) erlauben eine einfache, sicherere Montage von oben, gewährleisten ein ungehindertes Durchgleiten der bogenförmigen Brücken 1 und sichern auch gegen unsachgemäßes Herausreißen der Brücken 1 (21) mit den Endkappen 22 (den Unterstützungs- Tellern 2).Rounded Einclips-devices 6 (16) on the shoes 25 (15) allow a simple, safer mounting from above, ensure unhindered slipping through the arched bridges 1 and also secure against improper tearing out of the bridges 1 (21) with the end caps 22 (den Support plates 2).

Die bogenförmigen Brücken 1, 21, 21' sind hergestellt aus einem dauerelasischen KunststoffBand wie Hytrel®, Amitel®, ESPS, Makrolon®, oder ähnlichem, bzw. aus parallelen Flachband- oder Draht- Paaren aus denselben Kunststoffen bzw. aus Federstahl oder -bronze, die Einclips-Gleitschuhe 15, 25, auch die 5, 45 in Fig. 2,3 und 5 aus einem gleitfähigem, ggf. selbstschmierenden Kunststoff wie Delrin® oder auch aus Nylon® oder aus einem Kohlefaser-verstärktem Kunststoff.The arc-shaped bridge 1, 21, 21 'are made of a plastic tape dauerelasischen as Hytrel ®, Amitel ®, ESPS, Makrolon ®, or the like, or of parallel flat ribbon or wire pairs from the same plastic or of spring steel or -bronze , the Einclips sliding shoes 15, 25, and the 5, 45 in Fig. 2,3 and 5 of a lubricious, possibly self-lubricating plastic such as Delrin ® or nylon ® or a carbon fiber reinforced plastic.

Die elastischen, bogenförmigen Brücken 1, 21 erlauben zwei Arten der Hubanpassung:

  1. 1. Bei starker Absenkung von der unbelasteten Stellung I in die stark belastete Stellung II zweier benachbarter Endkappen- 22 (bzw. Unterstützungs- 2) -Elemente verformt sich der elastische Brücken- 1 (21) Bogen in eine liegende Doppel-S-Form durch Drehung der Achsen 3 (Querstege 13) an den Enden in den Laschen 4 (14), siehe linke Seite in Fig. 1 a.
  2. 2. Bei geringer Druckbelastung eines zu einem Endkappen- 22 (Unterstützungs-) Element etwa in Stellung II benachbarten Elementes wird dieses durch Durchgleiten der bogenförmigen Brücke 1(21) durch den (die) Gleitschuh(e) 25 (15) von Stellung I in die positive Hubstellung III angehoben, siehe rechte Seite von Fig. 1 a.
The elastic, arcuate bridges 1, 21 allow two types of Hubanpassung:
  1. 1. When strongly lowered from the unloaded position I to the heavily loaded position II of two adjacent end cap 22 (or support 2) elements, the elastic bridge 1 (21) arc deforms into a horizontal double S shape Rotation of the axes 3 (transverse webs 13) at the ends in the tabs 4 (14), see the left side in Fig. 1 a.
  2. 2. At low pressure load of an adjacent to an Endkappen- 22 (support) element approximately in position II element this by sliding through the arcuate bridge 1 (21) by the (the) shoe (s) 25 (15) of position I in raised the positive stroke position III, see the right side of Fig. 1 a.

Der Gesamthub h = hneg + hpos, siehe Fig. 1 a, setzt sich so aus einem negativen und positiven Hubanteil zusammen, wobei h ≥ H, der Gesamthub h größer als die Aufbauhöhe H ist. Dies gilt analog für die nicht- sowie für die gekreuzten, bogenförmige Brücken- 1', 11,11' bzw. 31, 31', 41 -Versionen, die in Fig. 2 bis 4 beschrieben sind.The total stroke h = h neg + h pos , see FIG. 1 a, is thus composed of a negative and positive stroke component, where h ≥ H, the total stroke h is greater than the assembly height H. This applies analogously to the non- as well as to the crossed, arcuate bridges 1 ', 11, 11' and 31, 31 ', 41 versions, respectively, which are described in FIGS. 2 to 4.

In Fig. 2 a und b und (c: dafür gelten die Elemente in Klammern) sind gezeigt Längschnitte durch und die Untersicht auf interaktive Unterstützungs- 2 Elemente mit elastischen, bogenförmigen, gekreuzten Brücken 11 (31). Die Brücken- 11(31) Bänder haben an beiden Enden beidseitig angeformte, runde Drehachsen 3 (einen Drehachsen- Quersteg 13), um die Einclips-Laschen 4 (14), welche an je zwei benachbarten Unterstützungs- Tellern 2 angeformt sind, durch (über) die Bänder 11 (31) greifend einrasten.In Figs. 2 a and b and (c: the elements in parentheses are shown) are shown longitudinal sections through and the bottom view of interactive support 2 elements with elastic, arcuate, crossed bridges 11 (31). The bridge 11 (31) bands have on both ends formed on both sides, round rotary axes 3 (a Drehachsen- transverse web 13) to the Einclips-tabs 4 (14), which are integrally formed on two adjacent support plates 2, by ( over) engage the bands 11 (31) in a gripping manner.

Die Brücken 11 (31) Bänder sind wieder etwa in ihrer Längsmitte durch Gleitschuhen 5 (15) gleitend unterstützt, die auf starren oder auf Federholz-Querleisten 10 befestigt.The bridges 11 (31) bands are again slidably supported approximately in their longitudinal center by sliding shoes 5 (15), which are fastened to rigid or spring-wood transverse strips 10.

Der Vorteil der in Fig. 2 über Kreuz angeordneten Brücken 11, 31 besteht in folgendem:

  1. 1. Die Neigung der hochgestellten geringer belasteten Unterstützungs-Elemente erfolgt immer zum abgesenkten, stärker belasteten Element hin.
  2. 2. Durch diese richtige Stufen-Ausbildung kommt es zu einer stark progressiv sich fortpflanzenden Koppelung der Unterstützungs- bzw. Endkappen-Elemente, da die gekreuzte, links oben angeschlagene Brücke 11, siehe Stellung III in Fig. 2 a, wieder zum nächsten rechten Unterstützungs-Element hin verschoben wird. Auf diese Weise kommt es zu einer starken Koppelung von mehr als fünf Unterstützungs-Elementen.
  3. 3. Durch die Doppel-S-förmige Verformung der gekreuzten Brücken 11 (31) ist wieder ein starkes Absenken auch direkt benachbarter Elemente möglich, siehe die zwei linken Unterstützungs- 2 Elemente in Fig. 2 a.
  4. 4. Es kommt also zu keiner Versteifung bei der Absenkung mehrerer, auch benachbarter Elemente bei starker, aufliegender Druckbelastung. Dies gilt auch für die in Fig. 1 bis 4 gezeigten Unterstützungs- bzw. Endkappen- Elemente.
The advantage of the bridges 11, 31 arranged crosswise in FIG. 2 consists in the following:
  1. 1. The slope of the raised lower loaded support elements is always towards the lowered, more heavily loaded element.
  2. 2. Through this correct stage training, there is a strong progressively propagating coupling of the support or end caps elements, since the crossed, top left battered bridge 11, see position III in Fig. 2a, back to the next right support Element is moved. In this way, there is a strong coupling of more than five support elements.
  3. 3. By the double S-shaped deformation of the crossed bridges 11 (31) again a strong lowering of directly adjacent elements is possible, see the two left support 2 elements in Fig. 2 a.
  4. 4. Thus, there is no stiffening in the lowering of several, even adjacent elements with strong, overlying pressure load. This also applies to the support or end cap elements shown in FIGS. 1 to 4.

In Fig. 2 b ist die Untersicht auf ein Unterstützungs- 2 Element mit den beiden gekreuzten Bücken 11, die im Bereich der möglichen Überlappung 19 Ausnehmungen 12 besitzen.In Fig. 2 b is the bottom view of a support 2 element with the two crossed stoop 11, which have 19 recesses 12 in the region of the possible overlap.

Bei der Ausnehmung 12 im Kreuzungsbereich 19 der Brücken 11 ist vorteilhafterweise die Wandstärke der Brücken 11 etwa proportional der dritten Potenz der verringerten Breite verstärkt, um etwa das gleiche Flächen- (biege) Moment zu erreichen.In the recess 12 in the crossing region 19 of the bridges 11, the wall thickness of the bridges 11 is advantageously increased approximately proportionally to the cube of the reduced width in order to achieve approximately the same area (bending) moment.

Die Flachdraht- Paar- Brücken 31 in Fig. 2 c sind um etwas mehr als die Band- bzw. Draht-Breite versetzt angeordnet.The flat-wire pair bridges 31 in FIG. 2 c are arranged offset by slightly more than the strip or wire width.

Natürlich können an den Brücken- 1, 11 Enden von Fig.1 und 2 auch Klammer- Ösen 9 wie an den Brücken 11' in Fig. 3, siehe unten, angeformt sein, die drehbar auf an den Endkappen 22 oder Unterstützungs-Tellern 2 angeformten Drehachsen eingerastet sind.Of course, at the bridge 1, 11 ends of Figs. 1 and 2, clip ears 9 as well as the bridges 11 'in Fig. 3, see below, may be integrally formed on the end caps 22 or support plates 2 rotatably molded rotary axes are engaged.

Fig. 3 a und b zeigen Läng- und Querschnitte durch eine Unterstützungs- 2 Element-Version mit gekreuzten, bogenförmigen Brücken 11', die in fixiertem Endabstand drehbar auf einem Schlitten 8 befestigt sind, der unter den Unterstützungs- Tellern 2 mit beidseitig angeformten Gleitkufen 39 in zwei Gleitschienen 23 verfahrbar ist. Zur Reduzierung der Reibung ist eine Hinterstechung 38 des Unterstützungs-Tellers 2' fast über die gesammte Breite der Gleitschienen- 23 Bahn vorgesehen.Fig. 3 a and b show longitudinal and cross sections through a support 2 element version with crossed, arcuate bridges 11 ', which are rotatably mounted at a fixed end distance on a carriage 8, which under the support plates 2 with both sides integrally formed skids 39 in two slides 23 is movable. To reduce the friction, a Hinterstechung 38 of the support plate 2 'is provided almost over the entire width of the Gleitschienen- 23 web.

Die gekreuzten Brücken 11' sind, wie im Querschnitt in Fig. 3 b gezeigt, um die Mitte der Breite in geringem Abstand voneinander versetzt angeordnet und haben über die fast gesamte Länge die gleiche Breite und Wandstärke, bis auf einen an beiden (oberen) Enden angeformten, gesamtbreiten Steg 29, an welchem Klammer- Ösen 9 angeformt sind Diese Klammer-Ösen 9 sind drehbar aufgeclipst auf an dem Schlitten 8 angeformte Drehachsen 7.The crossed bridges 11 'are, as shown in cross-section in Fig. 3 b, offset by the middle of the width at a small distance from each other and have the same width and wall thickness over almost the entire length, except for one at both (upper) ends integral, total width web 29, to which clip eyelets 9 are integrally formed These clip eyelets 9 are rotatably clipped on integrally formed on the carriage 8 axes of rotation. 7

Der Schlittens 8 hat etwa die halbe Länge der Unterstützungs- Teller 2 und ist über die gleiche Strecke verfahrbar.The carriage 8 has about half the length of the support plate 2 and can be moved over the same distance.

Die Verformung der Brücken 11' ist wegen des verfahrbaren Schlittens 8 deutlich geringer als die der Brücken 11 in Fig. 2, daher kann hier ihre Wandstärke etwas dicker gewählt werden, wodurch das Ausmaß der positiven Hubbewegung vorteilhaft begünstigt wird, siehe Fig. 3 a, rechtes Unterstützungs- 2 Element.The deformation of the bridges 11 'is significantly lower than that of the bridges 11 in Fig. 2 because of the movable carriage 8, therefore, here their wall thickness can be chosen slightly thicker, whereby the extent of the positive stroke movement is advantageously favored, see Fig. 3 a, right support 2 element.

Zur Begrenzung der Verfahrung des Schlittens 8 sind an den Längsseiten- Rändern der Unterstützungs-Teller 2 zwischen den Schienen 23 Stopper 36, 36' angebracht. Dabei kann ein Stopper 36 als Rand an den Unterstützungs-Teller 2 angeformt sein, während der andere Stopper 36', nach Einschieben des Schlittens 8 in die Gleitschienen 23 des Tellers 2, mittig dazwischen eingeclipst oder eingesteckt wird.To limit the passage of the carriage 8 stoppers 36, 36 'are mounted on the longitudinal side edges of the support plate 2 between the rails 23. In this case, a stopper 36 may be integrally formed as an edge on the support plate 2, while the other stopper 36 ', after insertion of the carriage 8 in the slide rails 23 of the plate 2, is clipped or inserted centrally in between.

Die anderen Elemente sind wie in Fig. 2 bezeichnet.The other elements are as indicated in Fig. 2.

Der Schlitten 8 verfährt beim Absenken der Brücken 11' um hneg zu jeweils entgegengesetzten Rändern benachbarter Unterstützungs-Teller 2 hin, wodurch die gekreuzten, an den Schlitten 8 aufgeclipsten, Bücken 11' durch die Gleitschuhe 5 zum jeweiligen außen liegenden Längsende des Nachbar-Unterstützungs-Element hin verschoben werden, siehe Fig. 3a, linke Unterstützungs-Elemente.The carriage 8 moves when lowering the bridges 11 'to h neg to each opposite edges of adjacent support plate 2 out, whereby the crossed, on the carriage 8 aufgeklipsten, stoop 11' through the shoes 5 to the respective outer longitudinal end of the Nachbar-Unterstützungs Element, see Fig. 3a, left support elements.

Ist das nächst gelegene Unterstützungs-Element mit geringerem Auflagedruck beaufschlagt, wird es um hpos nach oben gedrückt, siehe Fig. 3 a, rechtes Element, wobei der positive Hub hpos ≤ hneg fast die Größe von hneg und h = hneg + hpos > H erreichen kann.If the next support element is subjected to a lower contact pressure, it is pushed upwards by h pos , see FIG. 3 a, right element, where the positive stroke h pos ≦ h neg is almost the magnitude of h neg and h = h neg + h pos > H can reach.

Die Rückstellung ist aufgrund der paarweise an jedem Schlitten 8 angreifenden gekreuzten Brücken 11' gegeben.The provision is given due to the pairs of each carriage 8 attacking crossed bridges 11 '.

Somit ergeben sich für die in Fig. 3 a und b (sowie c und d) beschrieben Versionen die folgenden vorteilhaften Eigenschaften:

  • eine besonders aktive Kopplung der Unterstützungs-Elemente, mit
  • ein Anpassungshub h = hpos + hneg deutlich größer als die Aufbau-Höhe H, mit hpos ≤ hneg,
  • ohne die Doppel-S-förmige Verformung der gekreuzten Brücken, siehe Fig. 1a und 2a,
  • sowie eine ausgeprägte Zonen-Aufteilung möglich
  • Die Unterstützungs-Teller 2 (2') können sehr preiswert, ggf. mit Stabilisierungs-Stegen 37 an den Längs-Randseiten, in einem Extrudier-Verfahren hergestellt werden.
Thus, for the versions described in Figs. 3a and b (as well as c and d), the following advantageous properties result:
  • a particularly active coupling of the support elements, with
  • an adjustment stroke h = h pos + h neg significantly greater than the setup height H, with h pos ≤ h neg ,
  • without the double S-shaped deformation of the crossed bridges, see Figs. 1a and 2a,
  • and a pronounced zoning possible
  • The support plates 2 (2 ') can be produced very inexpensively, optionally with stabilizing webs 37 on the longitudinal edge sides, in an extrusion process.

Dies gilt auch für die vereinfachte Konstruktion, die in Fig. 3 c und d im Längs- und Querschnitt gezeigt ist, und in welcher der Schlitten 8 von Fig. 3 a und b ersetzt wird.This also applies to the simplified construction, which is shown in Fig. 3 c and d in the longitudinal and cross-section, and in which the carriage 8 of Fig. 3a and b is replaced.

An die Enden der hier nicht gekreutzen, bogenförmigen Brücken 1" ist je eine Gleit-Drehachse 30 angeformt, welche in zwei Gleitschienen 23' drehend laufen, die unterhalb des Unterstützungs- Tellers 2' angeformt sind.At the ends of the not gekreutzen here, arcuate bridges 1 "each have a sliding axis of rotation 30 is formed, which run in two slide rails 23 'rotating, which are formed below the support plate 2'.

Ein auf die Gleit- Drehachsen 30 jeweils neben den Brücken 1" aufgeclipster Abstands- Halter 18 verbindet diese und hält sie in definiertem Abstand, so daß der Halter 18 effektiv die Funktion des Schlittens 8 übernimmt.A distance holder 18, which is clipped onto the sliding axes of rotation 30 next to the bridges 1 "in each case, connects them and holds them at a defined distance, so that the holder 18 effectively takes over the function of the carriage 8.

Als Härte- und Zonen -Verstellung ist hier ein weiteres elastisches Rückstell-Element vorgesehen zusätzlich zu den Variations- Möglichkeiten der Shore-Härte der Brücken und der Kombination von Teller- und Endkappen- Elementen.As a hardness and zone Verstellung here another elastic return element is provided in addition to the variations possibilities of Shore hardness of the bridges and the combination of plate and Endkappen- elements.

Das zusätzliche Rückstell- Element ist ein Draht 64 aus Federstahl oder Rund- bzw. Flachstäben aus dauerelastischem Kunststoff eingesetzt in einer Öse 62 mittig angeformt an die Abstands- Klammern 18 und zwei Gleit-Ösen 63, die fest verbunden sind mit demThe additional return element is a wire 64 made of spring steel or round or flat bars made of permanently elastic plastic inserted in an eyelet 62 centrally formed on the distance brackets 18 and two sliding eyelets 63 which are firmly connected to the

Unterstützungs-Teller 2'. Dieser an den beiden äußeren Vierteln der Länge vorteilhafterweise gegen den Teller 2' hin abgekröpfte Rückstell-Draht 64 verbiegt sich in der Ebene unter dem Teller 2' zu einem Kreisbogen beim Verfahren der beabstandeten Drehachsen-30 Klammern 18 soweit, bis die beiden Haken 65 an beiden Enden des Drahtes an den Gleit-Ösen 63 anliegen.Support Dish 2 '. This at the two outer quarters of the length advantageously against the plate 2 'out bent back wire 64 bends in the plane below the plate 2' to a circular arc in the process of spaced rotary axes-30 brackets 18 so far until the two hooks 65 at abut both ends of the wire to the sliding lugs 63.

Die Stopper 36, 36' an den Längsenden des Tellers 2' können hier entfallen.The stoppers 36, 36 'at the longitudinal ends of the plate 2' can be omitted here.

Die Ösen 62 und 63 können auch mit Öffnungen zum Einclipsen des Rückstell-Drahtes 64 versehen werden.The eyelets 62 and 63 may also be provided with openings for clipping the return wire 64.

Der Vorteil der Versionen in Fig. 3 besteht weiterhin darin, daß die Unterstützungs-Teller 2 ihre Position unterhalb der Matratze weitestgehend beibehalten und so ein Schaben an dem Matratzenüberzug vermieden wird.The advantage of the versions in Fig. 3 further consists in that the support plates 2 maintain their position below the mattress as far as possible and so avoid scraping on the mattress cover.

Optimal ist der Einsatz dieser Unterstützungs-Elemente, siehe Fig. 3 (auch als Endkappen) für den Schulter- und Becken-Bereich, in Kombination mit den Unterstützungs-Elementen von Fig. 2 für den Kopf-, Lordose und Fuß-Bereich eines Bettunterrahmens. Auf diese Weise wird der negative Absenkungshub hneg am besten in aktiv positive Hubanpassung hpos umgesetzt durch die sehr effektive Weitergabe und Verteilung der im Schulter- und Becken-Bereich geleisteten Druckarbeit an die geringer druckbeaufschlagten Unterstützungs-Elemente. So werden die Druckspitzen ausgeglichen und vermieden, und eine optimaler Anpassung an alle Körper-Konturen in den vorkommenden Liegestellungen mit starker positiver Unterstützung erreicht. Auch eine Kombination von Einzel-Unterstützungs-Elementen mit Endkappen für Querleisten ergibt eine ausgeprägte Zonen-Ausbildung im Bettunterrahmen.Optimal is the use of these support elements, see Fig. 3 (also as end caps) for the shoulder and pelvic region, in combination with the support elements of Fig. 2 for the head, lordosis and foot region of a bed subframe , In this way, the negative lowering stroke h neg is best converted into actively positive stroke adjustment h pos by the very effective transfer and distribution of the work done in the shoulder and pelvic area to the less pressurized support elements. Thus, the pressure peaks are balanced and avoided, and achieved an optimal adaptation to all body contours in the existing reclining positions with strong positive support. Also, a combination of single support elements with end caps for cross bars results in a pronounced zonal formation in the bed subframe.

Die Erfahrung mit allen in dieser Anmeldung beschriebenen Unterstützungs- und Endkappen-Elementen zeigt, daß diese sich schon unter deutlich geringerer Belastung, als sie durch die Auflage einer Matratze von 7 bis 20 kg gegeben ist, wieder in eine Gleichgewichtslage, d.h. sich in gleiche Höhe der Unterstützungs-Teller oder der Endkappen mit Querleisten einstellt.The experience with all the support and end cap elements described in this application shows that they are in an equilibrium position, even under significantly lower load than is given by the support of a mattress from 7 to 20 kg. adjusts to the same height of the support plates or the end caps with transverse strips.

Fig. 4 a (und b) zeigt die Untersicht auf ein Unterstützungs-Element 2 mit einem (zwei) gleich breiten gekreuzten, bogenförmigen Flachband Brücken-Paaren 31 (31') aus elastischen Kunststoff, die alternierend anggeordnet sind und in Einzel- 24 (bzw. Doppel- 44) Einclips-Laschen, angeformt an den Unterstützungs-Tellern 2, mit endseitig angeformten, beidseitig überstehenden Drehachsen 33 eingerastet sind.4 a (and b) shows the bottom view of a support element 2 with a (two) equally wide crossed, arcuate flat band bridge pairs 31 (31 ') made of elastic plastic, which are arranged alternately and in individual 24 (FIG. or double 44) Einclips tabs, integrally formed on the support plates 2, are engaged with end formed on both sides protruding axes of rotation 33.

In Fig. 4 b ist die Untersicht gezeigt auf ein Unterstützungs- Element 2 mit bogenförmigen Brücken bestehend aus einem äußeren Flachband-Paar 31" und einem inneren, kreuzenden Brücken-Band 41, etwa doppelt so breit wie die beiden äußeren Bänder 3 1 "zusammen, alle jeweils aus Kunststoff. An die Bänder 31" bzw. 41 sind wieder endseitig, beidseitig überstehende Drehachsen 33' bzw, eine innere Drehachse 33", die in Einclips- Laschen 24 bzw. 44', angeformt an den Unterstützungs-Tellern 2 einrasten.In Fig. 4b, the bottom view is shown on a support element 2 with arcuate bridges consisting of an outer ribbon pair 31 "and an inner, crossing bridge band 41, about twice as wide as the two outer bands 3 1" together , all made of plastic. On the bands 31 "and 41 are again end, on both sides protruding axes of rotation 33 'and, an inner axis of rotation 33", which engage in Einclips- tabs 24 and 44', integrally formed on the support plates 2.

Diese Anordnungen in Fig. 4 a bis c benötigen keine Ausnehmungen mit einer Wandverstärkung der Bänder und gewährleisten ein gleichmäßiges, geführtes Absenken der Unterstützungs-Teller 2. Diese Bänder sind in einem Spritzgußverfahren aus dauerelastischem Kunststoff preiswert herstellbar.These arrangements in Fig. 4a to c need no recesses with a wall reinforcement of the bands and ensure a uniform, guided lowering of the support plate 2. These bands are produced inexpensively in an injection molding of permanently elastic plastic.

In Fig. 5 a und b ist die Untersicht auf und ein Längsschnitt gezeigt durch einen interaktiven, einstöckigen Matratzenkern mit einem Unterstützungs-Teller- 42 System mit gekreuzten, bogenförmigen Brücken-Paaren 51 aus Federstahl- Drähten, die etwas versetzt angeordnet sind. Die durchgehenden 53 und die unterbrochenen 53' endseitigen Querstege der Drahtpaare 51 sind in Einclips-Laschen 54 eingerastet, die versetzt an den Unterstützungs-Tellern 42 angeformt sind.In Figs. 5 a and b, the bottom view and a longitudinal section through an interactive, one-tier mattress core with a support plate 42 system with crossed, arcuate bridge pairs 51 of spring steel wires, which are arranged slightly offset. The continuous 53 and the interrupted 53 'end-side transverse webs of the wire pairs 51 are snapped into Einclips-tabs 54 which are offset to the support plates 42 integrally formed.

Die Minima der Brücken-Paare 51 laufen gleitend mit einer guten Seitenführung in je zwei Einclips-Gleitschuhen 45, die auf die Kreuzungspunkte eines Stahldraht-Netzes geclipst sind, das aus Längsdrähten 43 und aufgepunkteten Querdraht-Paaren 40 besteht.The minimums of the bridging pairs 51 slidingly provide good lateral guidance in each pair of clip-on shoes 45 which are clipped onto the intersections of a steel wire net consisting of longitudinal wires 43 and dotted cross wire pairs 40.

Abgerundete Einclips-Vorrichtungen 46 sichern die Draht-Brücken-Paare 51 gegen Herausrutschen und gewährleisten das ungehinderte Durchgleiten der Brücken-Drähte 51.Rounded clip-in devices 46 secure the wire-bridge pairs 51 from slipping out and ensure unhindered sliding of the bridge wires 51.

Das Draht-Netz 40, 43 liegt auf einer Schaum-Platte 47, z.B. aus Kaltschaum mit einem hohen Raumgewicht oder einem stabilen Polsterträger.The wire mesh 40, 43 rests on a foam plate 47, e.g. made of cold foam with a high volume weight or a stable padding support.

Auf den Unterstützungs-Tellern 42 liegt eine flexible, anpassungsfähige Kaltschaum- oder Latex-Platte 48 mit geringerem Raumgewicht, gefolgt von einer Vliesschicht 49 und umgeben von einem entsprechend elastischen Matratzen-Überzug 50.On the support plates 42 is a flexible, conformable cold foam or latex plate 48 of lesser density, followed by a nonwoven layer 49 and surrounded by a suitably resilient mattress cover 50.

Die Oberseite dieses Matratzenkerns ist sehr anpassungsfähig, mit einem interaktivem, negativen als auch positiven Hub, an jeden aufliegenden Körper mit allen oben in der Beschreibung von Fig. 1 bis 3 angeführten und geschilderten Vorteilen. Auf dieser Oberseite kann vorteilhafterweise auch eine separate Abschlußdecke aufgeclipst werden.The top of this mattress core is very adaptable, with an interactive, negative as well as positive stroke, to each resting body with all the advantages given and described above in the description of Figs. 1-3. On this top can be clipped advantageously also a separate end cover.

Die in Fig. 5 gezeigte Konstruktion kann auch zweistöckig gefertigt werden, durch gespiegelte Anordnung eines zweiten Unterstützungs-Teller- 42 -System mit gekreuzten, bogenförmigen Brücken-Paaren 51 auf der Unterseite des Stahldraht-Netzes, das dann als neutrale Faserebene fungiert. In dieser Version ist der Matratzenkern dann auch beidseitig gleich anpassungsfähig verwendbar.The construction shown in Fig. 5 can also be made in two stages by mirroring a second support plate 42 system with crossed arcuate bridge pairs 51 on the underside of the steel wire mesh, which then acts as a neutral fiber plane. In this version, the mattress core is then equally adaptable usable on both sides.

Die Unterstützungs-Teller- 42 können aus sehr preiswerten Massen- Kunststoffen wie Polypropylen (PP), Polyethylen (PE) oder ähnlichem hergestellt werden.The support plates 42 can be made from very inexpensive bulk plastics such as polypropylene (PP), polyethylene (PE) or the like.

Die in Fig. 3 a bis c beschriebenen Versionen, insbesondere die mit dem Abstands- Halter 18 beabstandeten nichtgekreuzten Brücken 1" aus einem Kunstoff Flachband kann vorteilhaft in einem Matratzenkern, zwischen Schamstoffplatten und Pölsterträgern, eingesetzt werden, vergleiche Fig. 5 a und b. Hierbei werden die Gleitschuhe 5 auf unteren Unterstützungs-Tellern (anstelle der Querleisten) und die Brücken- Enden drehbar mit den oberen Unterstützungs- Tellern verbunden. Hierbei bleibt die Lage der Unterstützungs- Tellern wieder weitestgehends erhalten, sodaß es zu keiner Abschabung an den Schamstoffplatten oder Pölsterträgern kommt.The versions described in FIGS. 3 a to c, in particular the non-crossed bridges 1 "made of a plastic flat strip spaced apart from the spacer holder 18, can advantageously be used in a mattress core, between filament plates and peat carrier, cf. FIGS. 5 a and b. In this case, the sliding blocks 5 on lower support plates (instead of the transverse strips) and the bridge ends are rotatably connected to the upper support plates.Here the position of the support plates is largely retained again, so that there is no scraping on the Schamstoffplatten or Pölsterträgern comes.

In Fig. 6 a und b ist der Längsschnitt durch und die Draufsicht gezeigt auf einen zweistöckigen Matratzenkern bestehend aus Bonnell- 56 oder LFK- Spiralfedern (Einhüllende gestrichelt gezeichnet) in alternierenden Reihen Schachbrett- artig angeordnet und verbunden mit sich kreuzenden, bogenförmigen Brücken- 51' Paaren, ebenfalls aus Federstahldraht.In Fig. 6 a and b, the longitudinal section through and the plan view is shown on a two-story mattress core consisting of Bonnell- 56 or LFK coil springs (envelope dashed lines drawn) arranged in alternating rows of checkerboard-like and connected with intersecting, arcuate bridges 51 'pairs, also made of spring steel wire.

Die Querstege 61 der Brücken- 51' Enden sind wellenförmig (bzw. gerade) ausgebildet, stehen über die äußeren Bonnell-Federendringe 55 hinaus und sind mit diesen in der mittigen Quersteg- 61 Einbuchtung mit Cramspangen 60 drehbar-beweglich verbunden. Auf diese Weise bekommen die Brücken 51', hier im oberen horizontalen Teil eine zusätzliche Stabilität gegen Verbiegung und es werden der große Abstand zwischen den beabstandeten Bonnell-Federendringen 55 etwa zur Hälfte überbrückt und ein Einklemmen der aufliegenden Schaumstoff-Platte vermieden.The transverse webs 61 of the bridge 51 'ends are wave-shaped (or straight), project beyond the outer Bonnell spring end rings 55 and are rotatably movably connected to them in the central transverse web 61 indentation with Cram clips 60. In this way, get the bridges 51 ', here in the upper horizontal part of an additional stability against bending and it is the large distance between the spaced Bonnell Federendringen 55 bridged about halfway and avoid jamming of the overlying foam sheet.

Das Hochstellen der überstehenden Querstege 61 ist selbst bei großen negativem und positivem Hub gering, da sich der Abknickwinkel zwischen den Brücken 51' und den Stegen 61 kaum ändert.The raising of the protruding transverse webs 61 is small even with large negative and positive stroke, since the Abknickwinkel between the bridges 51 'and the webs 61 barely changes.

Die Brücken- 51 Drähte sind vorteilhafterweise an einer Quersteg- 61 Welle mit einer Cramphülse 58 miteinander zu einem geschlossenen Gebilde verbunden. Die inneren Bonnell- Federendringe 55' sind mit durchgehenden Spiraldrähten 59 an jeweils gegenüberliegenden Seiten verbunden und bilden damit eine neutrale Faserebene des zweistöckigen Matratzenkerns aus. Diese Brücken-Paare 51' sind um eine Spiraldraht- 59 Windung versetzt angeordnet und berühren die innern Windungen der taillierten Bonnell-Federn 56 (Einhüllende in Fig. 6 a gestrichelt gezeichnet) auch beim Absenken nicht.The bridgewire wires are advantageously connected to one another at a transverse web 61 shaft with a crimp barrel 58 to form a closed structure. The inner Bonnell spring end rings 55 'are connected to continuous spiral wires 59 on respective opposite sides, thus forming a neutral fiber plane of the two-tier mattress core. These pairs of bridges 51 'are offset by a spiral winding 59 and touch the inner turns of the waisted Bonnell springs 56 (envelope in Fig. 6 a dashed lines) not even when lowering.

Die Mitten der Brücken 51' liegen in nebeneinander liegenden Windungen von je zwei querlaufenden, benachbarten Spiraldrähten 59 auf und werden so gleitend unterstützt. Ggf. ist der Mittelbereich der Brücken 51' zusätzlich mit einer Gleitschicht aus Gleitbronze, Teflon oder einem ähnlichen, selbstschmierenden Material beschichtet, um das ungestörte, lautlose Gleiten zu gewährleisten, oder die Brücken 51' bestehen aus (Gleit-) Bronze oder einer Duraluminum-Legierung.The centers of the bridges 51 'are located in adjacent turns of two transverse, adjacent spiral wires 59 and are thus supported slidably. Possibly. In addition, the central region of the bridges 51 'is additionally coated with a sliding layer of sliding bronze, Teflon or a similar self-lubricating material to ensure undisturbed, silent sliding, or bridges 51' are made of (sliding) bronze or a duraluminum alloy.

Versuche ergaben schon bei unbeschichteten Brücken- 51 Drähten ein geräuschloses Gleiten. Am Matratzenkern-Rand kann mindestens eine geschlossene Reihe Bonnell-Federn 56, oben und unten verbunden mit Spiral drähten 59, als Abschluß angeordnet sein.Experiments showed a noiseless glide even with uncoated bridge wires. At Matatzenkern edge at least one closed series Bonnell springs 56, connected at the top and bottom with spiral wires 59, be arranged as a conclusion.

Diese zwei Konstruktionen, Fig. 5 und 6, sind interaktiv gekoppelte Matratzenkerne mit positiver Hubanpassung.These two constructions, Figs. 5 and 6, are interactively coupled mattress cores with positive stroke adjustment.

Die in Fig. 6 ist nur aus Federstahl-Drähten und daher sehr preiswert herstellbar und hat die o.a. Vorteile, dazu eine zusätzliche Rückstellung aufgrund der Bonnell-Spiralfedern 56, aber auch eine etwas reduzierte positive Hubanpassung, je nach verwendeter Drahtstärke und Federkraft der Bonnell-Spiralfedern 56 und der bogenförmigen Brücken 51'.The in Fig. 6 is only spring steel wires and therefore very inexpensive to produce and has the o.a. Benefits, plus an additional provision due to the Bonnell coil springs 56, but also a slightly reduced positive Hubanpassung, depending on the wire size and spring force of the Bonnell coil springs 56 and the arcuate bridges 51 '.

Die in Fig. 5 und 6 gezeigten Draht-Brücken-Paar- 51 bzw. 51' Versionen können vorteilhafterweise auch nur in den kritischen Schulter-und Hüft- Bereichen des Matratzenkerns eingesetzt werden. Die restlichen Kopf- und Bein- Bereiche werden dann mit normalen Matratzenkern- (Bonnell-) Federn oder auch mit einem Schaumstoff-Kern ausgestattet.The wire-bridge pairs 51 and 51 'versions shown in FIGS. 5 and 6 can advantageously also be used only in the critical shoulder and hip regions of the mattress core. The remaining head and leg areas are then fitted with normal mattress core (Bonnell) springs or with a foam core.
