Description

Die vorliegende Erfindung betrifft eine Vorrichtung zur Härteneinstellung von Einzelstützelementen einer Stützvorrichtung, insbesondere einer Untermatratze.The present invention relates to a device for adjusting the hardness of individual support elements of a support device, in particular a base 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.Individual support elements have been known for a long time in spring mattresses and upholstered furniture. However, such individual support elements have also been used in place of conventional slats for spring frames for mattresses for some time. In particular in the shoulder and pelvic area, the selective support allows 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, an adjustment option for individual adjustment 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 support of different elasticity. This allows the spring stiffness to be changed.

Die CH 507 691 A zeigt eine Vorrichtung mit den Merkmalen des Oberbegriffs des Anspruchs 1. Eine weitere Vorrichtung zur Härteneinstellung von Einzelstützelementen einer Stützvorrichtung ist aus der DE 20 2005 003 749 U1 bekannt.The CH 507 691 A shows a device with the features of the preamble of claim 1. Another device for setting the hardness of individual support elements of a support device is from DE 20 2005 003 749 U1 known.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art anzugeben, die eine vorteilhafte Einstellmöglichkeit der Federhärte bietet.The invention is based on the object of specifying a device of the type mentioned at the outset which offers an advantageous possibility of setting the spring stiffness.

Diese Aufgabe wird durch eine Vorrichtung nach Anspruch 1 gelöst.This object is achieved by a device according to claim 1.

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.The use of a hardness adjustment element that can be rotated about a vertical axis enables the spring hardness to be adjusted easily. The hardness of two or more individual support elements can be adjusted at the same time by the push rod connecting at least two hardness setting elements.

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 setting of the hardness, an actuating arm is provided on at least one hardness setting element. The hardness setting element of the associated individual support element is adjusted with this actuating arm. At the same time, a corresponding setting of the hardness of the other individual support elements takes place automatically 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.In the case of several individual support elements arranged in a row with hardness setting elements connected via a push rod, actuating arms are particularly preferably provided on each of the two end hardness setting elements. As a result, the hardness can be adjusted from both sides, which is particularly advantageous in the case of a mattress base for a bed standing against a wall.

Nach der Erfindung weisen die Härteneinstellelemente Nocken auf, die zur Abstützung von Federarmen des jeweils zugehörigen Einstellelements dienen. Dabei können die Federarme in der ersten Stellung durch Nocken einer geringeren Höhe abgestützt werden als in der zweiten Stellung. 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 the invention, the hardness adjustment elements have cams which serve to support spring arms of the respectively associated adjustment element. The spring arms can be supported in the first position by cams of a lower height than in the second position. Alternatively or additionally, the cams that are effective in the first position can have a lower hardness than the cams that are effective in the second position. In this way, a different hardness can advantageously be set with simple means.

Fig. 5
a top view of the section of Fig. 4 .

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 section of a base mattress shown are attached in a row on a bar 2. Further such strips 2 with individual support elements 1 can be provided distributed over a base 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 at one end to the base 3 and are connected in pairs at their other ends via a support ring 5. An associated cover plate 6 is connected to the spring body of the individual support element formed by the spring arms 4 via the support rings 5 of an individual support element 1 (see FIG Figs. 3 to 5 ).

Unterhalb der Federarme 4 eines jeden Einzelstützelements 1 ist ein Härteneinstellring 7 vorgesehen. Dieser ist mit Nocken 8 ausgebildet, aufweichen 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.A hardness setting ring 7 is provided below the spring arms 4 of each individual support element 1. This is designed with cams 8, on which the spring arms 4 can be supported during compression. The hardness setting ring 7 can be rotated about a vertical axis I which coincides with the central axis of the spring element.

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 setting rings 7 takes place via an actuating arm 9 with a handle 10, which is provided on at least one of the hardness setting rings 7. The rotation of the hardness setting ring 7 provided with an actuating arm 9 is transmitted to the hardness setting rings 7 of the other individual support elements 1 via a push rod 11. For this purpose, the hardness adjustment rings 7 have tabs 12 to which the push rod 11 is pivoted. This does not prevent the hardness setting rings 7 from rotating, but the hardness setting rings 7 are coupled to one another, so that each rotation takes place jointly and in the same sense.

Erfindungsgemäß sind Nocken unterschiedlicher Höhe oder unterschiedlicher Elastizität vorgesehen, um eine unterschiedliche Härte einzustellen. Durch Verdrehen der Härteneinstellringe 7 über den Betätigungsarm 9 können die unterschiedlichen Nocken 8 zum Einsatz gebracht werden.According to the invention, cams of different heights or different elasticities are provided in order to set a different hardness. By turning the hardness setting rings 7 via the actuating arm 9, the different cams 8 can be used.
