Description

Die Erfindung betrifft ein neues Federelement, das z. B. in sogenannte Lattenroste eingesetzt wird und das vorwiegend in Sitz- oder Liegemöbelstücke verwendet wird. Der Lattenrost übernimmt in den meisten Fällen die Auflagefunktion für Matratzen oder Polster sowie die Grundhärteeinstellung für den Schlaf- bzw. Sitzkomfort.The invention relates to a new spring element, the z. B. in so-called Slatted frames are used, mainly in seating or reclining furniture is used. The slatted frame takes on the support function in most cases for mattresses or upholstery as well as the basic hardness setting for the Comfortable sleeping or sitting.

Bei einigen Lattenrosten ist die Härte durch Gummielemente, die zwischen zwei Federleisten verschiebbar gelagert sind, einstellbar. Bei anderen bekannten Konstruktionen, die eine Grundhärteverstellung der Federleisten realisiert haben, wird durch eine oder mehrere kürzere Federelemente, die an der Federleiste verschiebbar angebracht sind, die Härte der Federleiste eingestellt.With some slatted frames, the hardness due to rubber elements is between two Female connectors are slidably mounted, adjustable. With other known ones Constructions that have adjusted the hardness of the female connectors is by one or more shorter spring elements attached to the female connector are slidably attached, the hardness of the female connector is adjusted.

Die Nachteile dieser Konstruktionen sind in der Funktionsweise der Federleisten selbst begründet. Sie müssen aus statischen Gründen auf der Auflageseite ballig konvex ausgebildet sein, um einen einigermaßen kontinuierlichen Höhenverlauf sowie einer entsprechenden Rückstellkraft der Federleisten zu gewährleisten. Bauartbedingt ist keine gleichmäßige punktuelle Druckdurchbiegung an jeder Stelle der Federleiste zu realisieren. Eine einigermaßen genaue Grundhärteeinstellung der Federleisten in einem Bettlattenrost und in den drei Komfortzonen, Kopf-, Fuß- und Schulterbereich, ist mit diesen bekannten Ausführungen nicht zu realisieren.The disadvantages of these designs are in the way the female connectors work self-justified. For structural reasons they must be crowned on the support side be convex to have a reasonably continuous height profile as well as a corresponding restoring force of the female connectors. Due to the design, there is no uniform punctual pressure deflection on everyone Realize the female connector. A reasonably accurate basic hardness setting the slats in a slatted bed frame and in the three comfort zones, Head, foot and shoulder area is not possible with these known designs realize.

Aufgrund dieser bauartbedingten Nachteile der Federleisten ist ein Schlaf- bzw. Liege- und Sitzkomfort nur durch technisch aufwendige Matratzen und Polsterkonstruktionen, die zwangsläufig zu einer hohen Bauhöhe führen, zu realisieren. Dadurch wird auch die Durchlüftung und Feuchtigkeitsabgabe der Matratzen bzw. Polster erschwert.Due to these design-related disadvantages of the female connectors, a sleeping or Lying and sitting comfort only through technically complex mattresses and upholstery constructions, which inevitably lead to a high overall height. This also ensures the ventilation and moisture release of the mattresses or Upholstery difficult.

Gravierend wird dieser Nachteil bekannter Lattenrostkonstruktionen besonders bei der Verwendung in Pflegebetten, in denen Patienten über einen längeren Zeitraum verweilen. Hier liegen ganz unterschiedliche Patienten mit unterschiedlichem Körpergewicht, ihren individuellen Körperformen und mit ganz unterschiedlichen Krankheitsbildern in der Regel auf einem standardisierten Lattenrost ohne jegliche Verstellmöglichkeit der Auflagehärte. Die darauf befindliche einfache Matratze kann diese bauartbedingten konstruktiven Nachteile des Lattenrostes nicht kompensieren.This disadvantage is particularly serious with known slatted frame constructions use in nursing beds in which patients have an extended period of time Linger period. There are very different patients here different body weights, their individual body shapes and with whole different clinical pictures usually on a standardized Slatted frame without any adjustment of the hardness. The one on it A simple mattress can have these design-related disadvantages do not compensate for the slatted frame.

Ähnliche Problembereiche bestehen im Bürostuhlbereich und bei Autositzen. Auch hier sind individuelle Einstellungsmöglichkeiten in bezug auf Sitzkomfort und anatomisch richtiges Sitzen für die Benutzergruppen nicht optimal gelöst.Similar problem areas exist in the office chair area and car seats. Here, too, there are individual setting options with regard to seating comfort and anatomically correct sitting not optimally solved for the user groups.

Der im Patentanspruch 1 und den Unteransprüchen angegebenen Erfindung liegt das Problem zugrunde, ein in der Härte einfach und genau einzustellendes Federelement zu schaffen ,das vorwiegend in Lattenrosten von Betten, Büroarbeitsstühlen oder Autositzen eingesetzt werden soll.The invention specified in claim 1 and the dependent claims based on the problem of a hardness that is simple and precisely adjustable To create spring element, which is mainly in slatted frames of beds, Office work chairs or car seats should be used.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß zwischen den Auflagepunkten in Längsrichtung des Federelementes ein Spannelement, welches in wenigstens einer ersten Querrichtung auslenkbar ist, mit einstellbarer Vorspannung auf Zug gespannt ist und entlang dem Spannelement auf der Belastungsseitezwischen den Auflagepunkten miteinander verbundene Kettenelemente so angeordnet sind, daß sich die Kettenelemente in Längsrichtung aneinander abstützen und um Schwenkachsen, die quer zur Längsrichtung und quer zur ersten Querrichtung verlaufen, relativ zueinander schwenkbar sind. According to the invention the object is achieved in that between the support points in the longitudinal direction of the spring element, a clamping element, which in at least a first transverse direction is deflectable, with adjustable Preload is tensioned on train and along the tensioning element on the Chain elements connected to one another between the load points are arranged so that the chain elements in the longitudinal direction support each other and about swivel axes that are transverse to the longitudinal direction and extend transversely to the first transverse direction, are pivotable relative to one another.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß das in seiner Härte leicht und genau einstellbare Federelement besonders für Pflegebetten, zu Hause oder in Krankenhäusern, Kliniken, Sanatorien, Alten- und Pflegeheimen, geeignet ist, da hier besondere variable Einstellwerte bezüglich der Druckverteilung und Einsinktiefe im Auflagebereich gefordert werden. Zudem sind die meisten Pflegebetten im Kopf- und Fußteil verstellbar und die Matratze kann daher, da ihre Bauhöhe aufgrund der Biegeanforderungen geringer ist als eine normale Schlafmatratze, nicht die Funktion einer optimalen anatomischen Abstützung der Wirbelsäule und der Lendenwirbelsäule übernehmen. Von daher kommt dem Lattenrost eine besondere Bedeutung bezüglich der Einsinktiefe und Druckverteilung zu.The advantages achieved by the invention are in particular that the in its hardness easily and precisely adjustable spring element especially for Nursing beds, at home or in hospitals, clinics, sanatoriums, old people's and Nursing homes, is suitable, since here special variable setting values with regard to the Pressure distribution and sinking depth in the support area are required. Also are most nursing beds adjustable in the head and foot section and the mattress can this is because their height is less than one due to the bending requirements normal sleeping mattress, not the function of an optimal anatomical Support the spine and lumbar spine. Due to this the slatted frame is of particular importance with regard to the sinking depth and Pressure distribution too.

Durch die Verwendung eines Obergurtes der in Querrichtung auslenkbar, jedoch in Längsrichtung druckfest ist, entsteht eine vom Druckpunkt ausgehende breitere Einsinktiefe und damit eine längere Druckverteilungskurve, mit einem kontinuierlichen Verlauf. Eine optimale Einsinktiefe an den Auflagepunkten des Federelementes z. B. bei der Verwendung von zwei Lattenrosten für ein breites Doppelbett, ist durch die Verwendung von zwei Federelementen, die in ihrer Auslenkungsrichtung zueinander kombiniert sind, zu erreichen.By using a top chord that can be deflected in the transverse direction, however is pressure-resistant in the longitudinal direction, a wider one arises from the pressure point Sink depth and thus a longer pressure distribution curve, with a continuous Course. An optimal sinking depth at the contact points of the spring element z. B. when using two slatted frames for a wide Double bed, is through the use of two spring elements that are in their Direction of deflection are combined to achieve each other.

Im Sitzbereich, z. B. bei Büroarbeitsstühlen ,wird durch die Verwendung des Federelementes im Sitz- wie im Rückenlehnenbereich ein weitgehend dynamisches und druckausgleichendes Sitzen ermöglicht. Durch die Verwendung von Federelementen mit Mittelgurt in der Rückenlehne von Autositzen kann die Aufprallenergie, die bei einem Heckauffahrunfall durch einen anderen PKW für den Fahrer im vorderen PKW entsteht, der in dieser Situation gegen die Rückenlehne gepreßt wird, dadurch für den Fahrer reduziert werden, daß die Rückenlehne kontrolliert nach hinten und für den Fahrer dämpfend ausweichen kann.In the seating area, e.g. B. in office chairs, is through the use of Spring element in the seat and backrest area a largely dynamic and enables pressure-equalized sitting. By the use of Spring elements with center belt in the backrest of car seats can Impact energy caused by another car in a rear-end collision the driver in the front car arises, who in this situation against the Backrest is pressed, this can be reduced for the driver that the Control the backrest backwards and dodge it for the driver can.

Eine weitere vorteilhafte Ausgestaltung der Erfindung ist neben der einfachen manuellen Einstellung der Härte der Federelemente, z. B. durch einen einfachen Drehmomentschlüssel, die programmierte Steuerung der Härte von einzelnen Federelementen mittels Software und elektrischer Schrittmotoren. Besonders vorteilhaft ist diese Anwendung bei Pflege- und Krankenhausbetten mit einer ständig wechselnden Bettenbelegung und unterschiedlichen Krankheitsbildern der Patienten. Bei Langzeit- und pfegebedürftigen Patienten kann aus medizinischen Gesichtspunkten über einen festgelegten Zeitraum eine intervallmäßige Steuerung der Härte von unterschiedlichen Härtezonen oder von einzelnen Federelementen über die elektronische Steuerung realisiert werden. Ausführungsbeispiele der Erfindung werden im folgenden unter Bezugnahme auf die beigefügten Zeichnungen näher beschrieben.A further advantageous embodiment of the invention is in addition to the simple one manual adjustment of the hardness of the spring elements, e.g. B. by a simple Torque wrench, the programmed control of hardness by individual Spring elements using software and electrical stepper motors. Especially This application is advantageous for nursing and hospital beds with one constantly changing bed occupancy and different clinical pictures of the Patients. Long-term and long-term care patients can be out of medical Intermittent control over a defined period of time the hardness of different hardness zones or of individual spring elements can be realized via the electronic control. embodiments of the invention will hereinafter be described with reference to the accompanying Drawings described in more detail.

Die Figuren 29 und 30 zeigen im Längs- sowie Querschnitt eine Variante, bei der der Obergurt 14 in Abständen gegen das Spannelement 4 abragende, insbesondere einstückig ausgebildete, Fortsätze 14' aufweist. Die Kettenelemente 1 sind auf die freien Enden der Fortsätze 14' aufgesteckt und nehmen diese in entsprechend geformten Taschen auf, die etwas größer ausgebildet sind als die Fortsätze 14'. Bei Belastung auf den Obergurt quer zum Spannelement verformt sich der Obergurt 14, so daß unter Umständen auch die Fortsätze 14' nicht mehr exakt zueinander parallel stehen, und die aneinander grenzenden Kettenelemente 1 rollen etwas mit ihren gegeneinander gerichteten Stirnseiten 9 aneinander ab entsprechend der Wirkung eines Gelenkes. Das Spannelement 4 kann ein Spanngurt sein, der an einer unteren Nut der Kettenelemente 1 liegt.Figures 29 and 30 show in longitudinal and cross section a variant in which the upper flange 14 protrudes at intervals against the tensioning element 4, has in particular integrally formed extensions 14 '. The chain elements 1 are plugged onto the free ends of the extensions 14 'and take them in appropriately shaped pockets that are slightly larger than that Extensions 14 '. Deformed transversely to the tensioning element when loaded on the top chord the upper chord 14, so that under certain circumstances also the extensions 14 'no longer are exactly parallel to each other, and the adjacent chain elements 1 roll something against each other with their mutually facing end faces 9 according to the effect of a joint. The clamping element 4 can be a Be tension belt, which lies on a lower groove of the chain elements 1.

Wie die Aufsicht der Fig. 33 zeigt, erstreckt sich der Obergurt zu beiden Seiten um ein Mehrfaches der Breite der Fortsätze 14' über diese seitlich hinaus, ist in Längsrichtung von den Seiten her in Abständen eingeschnitten bis etwa auf die Tiefe der Fortsätze 14' und weist in diesen seitlichen Überständen großflächige Durchbrüche auf. Ein solches Federelement bietet auf großer Fläche eine Abstützung, ohne innerhalb dieser Fläche eine Durchlüftung durch den Obergurt 14 hindurch vollständig zu behindern.As the top view of FIG. 33 shows, the upper flange extends on both sides a multiple of the width of the extensions 14 'beyond these laterally is in Cut longitudinally from the sides at intervals apart from about Depth of the extensions 14 'and has large areas in these lateral projections Breakthroughs. Such a spring element provides support over a large area, without ventilation through the upper chord 14 within this area completely hindering it.

Fig. 35 zeigt eine ähnliche Ausführungsform wie Fig. 25, mit dem Unterschied, daß auf der vom Spannelement 4 abgewandten Seite der Kettenelemente 1 auf jedem Kettenelement ein quer zur Richtung des Spannelementes 4 seitlich weit überstehender Querausleger 28 angeordnet ist, um ebenfalls durch ein einziges Federelement eine breite Unterstützungsfläche zu bieten. Die Kettenelemente 1 können dabei über einzelne Gelenke miteinander verbunden sein oder über einen Obergurt 14.35 shows a similar embodiment to FIG. 25, with the difference that that on the side facing away from the tensioning element 4 of the chain elements 1 each chain element laterally far to the direction of the tensioning element 4 projecting cross-arm 28 is arranged to also by a single Spring element to offer a wide support surface. The chain elements 1 can be connected to each other via individual joints or via a Upper chord 14.
