Description

Die vorliegende Erfindung betrifft eine Vorrichtung zur Härteneinstellung von Einzelstützelementen einer Stützvorrichtung, insbesondere einer Untermatratze.The present invention relates to a device for setting the hardness of individual support elements of a support device, in particular a lower mattress.

Bei Federkernmatratzen und Polstermöbeln sind Einzelstützelemente seit langem bekannt. Aber auch bei Federrahmen für Matratzen werden seit einiger Zeit derartige Einzelstützelemente anstelle der herkömmlichen Latten eingesetzt. Insbesondere im Schulter- und Beckenbereich kann durch die punktuelle Abstützung ein tieferes Eintauchen und damit eine Verbesserung des Liegekomforts erreicht werden.In spring mattresses and upholstery individual support elements have long been known. But even with spring frames for mattresses such single support elements are used instead of the conventional slats for some time. In particular, in the shoulder and pelvic area can be achieved by the selective support a deeper immersion and thus an improvement in lying comfort.

Wie bei herkömmlichen Lattenrosten ist auch bei Federrahmen mit Einzelstützelementen eine Einstellmöglichkeit zur individuellen Anpassung der Federeigenschaften wünschenswert. Hierfür ist es bekannt, die Federelemente der Einzelstützelemente unterschiedlich abzustützen und dadurch entweder den Federweg zu verändern oder eine Abstützung unterschiedlicher Elastizität bereitzustellen. Hierdurch kann die Federhärte verändert werden.As with conventional slatted frames, a setting option for individual adaptation of the spring properties is also desirable for spring frames with individual support elements. For this purpose, it is known to support the spring elements of the individual support elements differently and thereby either to change the spring travel or to provide a support of different elasticity. As a result, the spring hardness can be changed.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art anzugeben, die eine vorteilhafte Einstellmöglichkeit der Federhärte bietet.The invention has for its object to provide a device of the type mentioned, which offers an advantageous adjustment of the spring rate.

Diese Aufgabe wird durch eine Vorrichtung nach Anspruch 1 gelöst und insbesondere durch eine Vorrichtung zur Härteneinstellung von Einzelstützelementen einer Stützvorrichtung, insbesondere einer Untermatratze, mit einem um eine vertikale Achse zwischen einer ersten Stellung mit einer ersten Federhärte des Einzelstützelements und einer zweiten Stellung mit einer zweiten Federhärte des Einzelstützelements verdrehbaren Härteneinstellelement, insbesondere Härteneinstellring, wobei mindestens zwei Härteneinstellelemente über eine Schubstange derart miteinander verbunden sind, dass sich die beiden Härteneinstellelemente gemeinsam und gleichsinnig verdrehen.This object is achieved by a device according to claim 1 and in particular by a device for setting the hardness of individual support elements of a supporting device, in particular a lower mattress, with a vertical to a Axle between a first position with a first spring stiffness of the single support member and a second position with a second spring hardness of the single support member rotatable Härteinstellelement, in particular Härteinstellring, wherein at least two Härteinstellelemente are interconnected via a push rod such that the two hardening elements rotate together and in the same direction.

Durch die Verwendung eines um eine vertikale Achse verdrehbaren Härteneinstellelements ist eine einfache Verstellung der Federhärte möglich. Durch die mindestens zwei Härteneinstellelemente verbindende Schubstange können zwei oder mehr Einzelstützelemente gleichzeitig in ihrer Härte verstellt werden.By using a hardening element which can be rotated about a vertical axis, a simple adjustment of the spring hardness is possible. By connecting at least two hardening elements connecting push rod two or more individual support elements can be adjusted simultaneously in their hardness.

Zur Erleichterung der Härteneinstellung ist an mindestens einem Härteneinstellelement ein Betätigungsarm vorgesehen. Mit diesem Betätigungsarm wird das Härteneinstellelement des zugeordneten Einzelstützelements verstellt. Über die Schubstange erfolgt zugleich automatisch eine entsprechende Härteneinstellung der anderen Einzelstützelemente.To facilitate the hardening adjustment, an actuating arm is provided on at least one hardness setting element. With this actuating arm, the hardness setting element of the associated individual support element is adjusted. At the same time, a corresponding hardness setting of the other individual support elements takes place via the push rod.

Besonders bevorzugt sind bei mehreren in einer Reihe angeordneten Einzelstützelementen mit über eine Schubstange verbundenen Härteneinstellelementen jeweils an den beiden endseitigen Härteneinstellelementen Betätigungsarme vorgesehen. Dadurch kann die Härteneinstellung von beiden Seiten erfolgen, was insbesondere bei einer Untermatratze eines an einer Wand stehenden Bettes vorteilhaft ist.Particularly preferably, in a plurality of individual support elements arranged in a row with hardening adjustment elements connected via a push rod, actuation arms are respectively provided on the two end-side hardening setting elements. As a result, the hardening adjustment can take place from both sides, which is advantageous in particular with a lower mattress of a bed standing on a wall.

Nach einer speziellen Ausgestaltung der Erfindung weisen die Härteneinstellelemente Nocken auf, die zur Abstützung von Federarmen des jeweils zugehörigen Einstellelements dienen. Dabei kann in der ersten Stellung der Härteneinstellvorrichtung eine kleinere Anzahl von Federarmen über Nocken abgestützt sein als in der zweiten Stellung. Alternativ oder zusätzlich können die Federarme in der ersten Stellung durch Nocken einer geringeren Höhe abgestützt werden als in der zweiten Stellung. Ebenfalls alternativ oder zusätzlich können die in der ersten Stellung wirksamen Nocken eine geringere Härte aufweisen als die in der zweiten Stellung wirksamen Nocken. Auf diese Weisen kann eine unterschiedliche Härte mit einfachen Mitteln vorteilhaft eingestellt werden.According to a special embodiment of the invention, the hardening elements have cams which serve to support spring arms of the respectively associated adjusting element. In this case, a smaller number of spring arms may be supported via cams in the first position of the Härteinstellvorrichtung than in the second position. Alternatively or additionally, the spring arms in the first Position be supported by cams of a lower height than in the second position. Also alternatively or additionally, the effective in the first position cams may have a lower hardness than the effective in the second position cams. In this way, a different hardness can be set advantageously with simple means.

Die Einzelstützelemente 1 des dargestellten Abschnitts einer Untermatratze sind in einer Reihe auf einer Leiste 2 angebracht. Weitere derartige Leisten 2 mit Einzelstützelementen 1 können über eine Untermatratze verteilt vorgesehen sein.The individual support elements 1 of the illustrated portion of a lower mattress are mounted in a row on a bar 2. Other such strips 2 with individual support elements 1 may be provided distributed over a lower mattress.

Die Einzelstützelemente 1 bestehen jeweils aus einer Basis 3 und Federarmen 4, die mit in ihrem einen Ende an der Basis 3 angesetzt sind und paarweise mit ihren anderen Enden über einen Stützring 5 verbunden sind. Über die Stützringe 5 eines Einzelstützelements 1 ist eine zugehörige Deckplatte 6 mit dem durch die Federarme 4 gebildeten Federkörper des Einzelstützelements verbunden (siehe Fig. 3 bis 5).The individual support elements 1 each consist of a base 3 and spring arms 4, which are attached with in one end to the base 3 and in pairs with their other ends are connected via a support ring 5. Via the support rings 5 of a single support element 1, an associated cover plate 6 is connected to the spring body of the single support element formed by the spring arms 4 (see Fig. 3 to 5 ).

Unterhalb der Federarme 4 eines jeden Einzelstützelements 1 ist ein Härteneinstellring 7 vorgesehen. Dieser ist mit Nocken 8 ausgebildet, auf welchen sich die Federarme 4 beim Einfedern abstützen können. Der Härteneinstellring 7 ist um eine vertikale Achse I, die mit der zentralen Achse des Federelements zusammenfällt, verdrehbar. In einer ersten Drehstellung des Härteneinstellrings 7 befinden sich vier Nocken im Einfederweg von vier Federarmen 4, während in einer zweiten Drehstellung acht Nocken 8 im Federweg der acht Federarme 4 befindlich sind. Dabei ergibt sich in der ersten Stellung des Härteneinstellrings 7 eine geringere Härte als in der zweiten Stellung.Below the spring arms 4 of each individual support element 1, a hardness setting ring 7 is provided. This is formed with cams 8, on which the spring arms 4 can be supported during compression. The hardness adjusting ring 7 is rotatable about a vertical axis I, which coincides with the central axis of the spring element. In a first rotational position of the Härteinstellrings 7 are four cams in the compression travel of four spring arms 4, while in a second rotational position eight cams 8 in the spring travel of the eight spring arms 4 are located. This results in the first position of the hardness setting 7 a lower hardness than in the second position.

Die Verstellung der Härteneinstellringe 7 erfolgt über einen Betätigungsarm 9 mit einem Handgriff 10, der an mindestens einem der Härteneinstellringe 7 vorgesehen ist. Über eine Schubstange 11 wird die Verdrehung des mit einem Betätigungsarm 9 versehenen Härteneinstellrings 7 auf die Härteneinstellringe 7 der anderen Einzelstützelemente 1 übertragen. Hierfür weisen die Härteneinstellringe 7 Laschen 12 auf, an denen die Schubstange 11 drehbar angelenkt ist. Dadurch wird ein Verdrehen der Härteneinstellringe 7 nicht behindert, die Härteneinstellringe 7 aber miteinander gekoppelt, so dass eine Verdrehung jeweils gemeinsam und im gleichen Sinne erfolgt.The adjustment of the hardness adjustment rings 7 via an actuating arm 9 with a handle 10 which is provided on at least one of the hardness setting rings 7. Via a push rod 11, the rotation of the provided with an actuating arm 9 Härteinstellrings 7 is transmitted to the Härteinstellringe 7 of the other single support elements 1. For this purpose, the hardness adjustment rings 7 lugs 12 on which the push rod 11 is pivotally articulated. As a result, twisting of the hardness setting rings 7 is not hindered, but the hardness setting rings 7 are coupled with each other, so that rotation takes place together and in the same sense.

Anstelle einer unterschiedlichen Anzahl von Nocken 8, durch welche die Federarme 4 abgestützt werden, können auch Nocken unterschiedlicher Höhe oder unterschiedlicher Elastizität vorgesehen werden, um eine unterschiedliche Härte einzustellen. Durch Verdrehen der Härteneinstellringe 7 über den Betätigungsarm 9 können die unterschiedlichen Nocken 8 zum Einsatz gebracht werden.Instead of a different number of cams 8, by which the spring arms 4 are supported, also cams of different height or different elasticity can be provided to adjust a different hardness. By rotating the Härteinstellringe 7 via the actuating arm 9, the different cams 8 can be used.
