Description

Die Erfindung betrifft eine Untermatratze mit Querträgern als Auflage für eine Obermatratze, bei der jeder Querträger mittels eines in seiner Federstärke veränderbaren elastischen Verbindungsstückes am Auflagerahmen der Untermatratze befestigt ist, wobei jedes Verbindungsstück eine Druckfeder aufweist, die mittels einer Einstellmutter vorspannbar ist.The invention relates to a bottom mattress with cross members as a support for a top mattress, in which each cross member is fastened to the support frame of the bottom mattress by means of an elastic connecting piece which can be changed in spring strength, each connecting piece having a compression spring which can be pretensioned by means of an adjusting nut.

Eine derartige Untermatratze ist nach der DE-AS 25 32 583 bekannt. Die Federung aus Gummischeiben oder Schraubenfedern kann maximal 1 cm vorgespannt werden, während der Federweg maximal 2 cm beträgt.Such a bottom mattress is known from DE-AS 25 32 583. The suspension made of rubber washers or coil springs can be preloaded by a maximum of 1 cm, while the spring travel is a maximum of 2 cm.

Der genannte Vorspannwert der Federung von 1 cm führt dazu, daß unterschiedliche Körpergewichte, z.B. von 50 oder 100 kg, nicht ausreichend in der Federhärte berücksichtiqt werden können. Außerdem reicht der Federweg von 2 cm nicht aus, um bei einer Obermatratze von handelsüblicher Elastizität auch in der Seitenlage, also bei einer geringeren Auflagefläche und höherem Auflagedruck die Ausbuchtungen des Körpers im Schulter- und Hüfthprpich durch den Federdruck der Untermatratze so aufzufangen, daß ein orthopädisch entspanntes und gesundes Liegen ermöglicht wird. Wegen der geringen Vorspannmöglichkeit und des niedrigen Federweges ist es nur in Einzelfällen möglich, das Gefühl eines Schwebezustandes zu vermitteln. Unzweckmäßig ist weiter, daß die Querträger in ihrer Stabilität durch die im Verhältnis zu ihrer Dicke relativ große kalottenförmige Ausbildung geschwächt werden, sodaß es bei einem höheren Körpergewicht bei maximaler Vorspannung, während einer ruckartigen Schlafbewegung zum Bruch eines Querträgers kommen kann bzw. ein Querträger aus seiner kardanischenAufhängung kippt.Said bias value of the suspension of 1 cm resulting in different body weights, for example kg of 50 or 100, can not be sufficiently in the spring hardness berücksichti q t. In addition, the spring travel of cm is not enough of 2 to I collect at a top mattress of commercial elasticity also in the side position, that is at a lower support surface and a higher contact pressure, the protrusions of the body in the shoulder and Hüfth p r p by the spring pressure of the base mattress so that an orthopedically relaxed and healthy lying is made possible. Due to the low preloading option and the low spring travel, it is only possible in individual cases to convey the feeling of a floating state. It is furthermore unsuitable that the stability of the crossbeams is weakened by the dome-shaped design, which is relatively large in relation to its thickness, so that, with a higher body weight with maximum preload, a crossbeam or a crossbeam can break out of it during a jerky sleep movement gimbal tilts.

Der Erfindung liegt die Aufgabe zugrunde, diese Nachteile zu vermeiden, indem die Vorspannung der Federung und der Federweg so vergrößert werden, daß sie für alle vorkommenden Körpergewichte ausreichend sind.The invention has for its object to avoid these disadvantages by increasing the preload of the suspension and the spring travel so that they are sufficient for all occurring body weights.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß jedes Verbindungsstück aus einer in einer Aufnahmebohrung des Auflagerahmens angeordneten und mit diesem fest verbundenen unteren Teleskophülse zur Aufnahme der Einstellmutter und des unteren Teiles der Druckfeder sowie einer mit der unteren verbundenen oberen Teleskophülse besteht, welch letztere mit dem Querträger fest verbunden ist und den oberen Teil der Druckfeder aufnimmt, wobei beide Teleskophülsen in der Weise miteinander verbunden sind, daß die obere Hülse in ihrer Bewegung nach oben durch den Einstelldruck der Druckfeder begrenzt ist.This object is achieved in that each connector consists of an arranged in a receiving bore of the support frame and firmly connected to this lower telescopic sleeve for receiving the adjusting nut and the lower part of the compression spring and one connected to the lower connected upper telescopic sleeve, the latter with the cross member is firmly connected and receives the upper part of the compression spring, both telescopic sleeves being connected to one another in such a way that the upper sleeve is limited in its upward movement by the setting pressure of the compression spring.

Weiterbil dungen der Erfindung sind in den Unteransprüchen enthalten. Insbesondere durch die Maßnahme des Anspruchs 5 mit der Anordnung eines Halteknopfes und einer Verstellschraube und deren Verbindung durch einen Haltestrang wird erreicht, daß sich die Querträger in der Liegestellung nicht verschieben und bei Nichtbelastung in der Liegeebene gehalten werden.Further developments of the invention are contained in the subclaims. In particular, by the measure of claim 5 with the arrangement of a holding button and an adjusting screw and their connection by a holding strand is achieved that the crossbeams do not move in the lying position and are held in the lying level when not in use.

In Fig. 1 ist in einem Längsquerschnitt eine erste Ausführungsform der Erfindung dargestellt. Sie zeigt einen Auflegerahmen 1 mit einer Aufnahmebohrung 2, in der eine untere Teleskophülse 3 an Befestigungsschrauben 8 angeordnet ist. In der unteren Teleskophülse befindet sich eine Einstellmutter 6 mit Schüssellöchern 7. Weiterhin weist die Hülse ein Innengewinde 4 und eine nach innen zeigende Abkröpfung 5 auf, die eine obere Teleskophülse 9 an deren nach außen zeigender Abkröpfung 10 durch den Einstelldruck einer Druckfeder 14 in ihrer Bewegung nach oben arretiert, so daß der Gesamtfederweg durch die Höhe der oberen Teleskophülse vorgegeben ist. Auf der Oberfläche der Teleskophülse befinden sich in deren Mitte Befestigungsschrauben 11, die einen Querträger 13 über einen Gummipuffer 12 fixieren. Die Vorspannung der Druckfeder 14 wird an den Schlüssellöchern 7 mit einem passenden Schlüssel vorgenommen. Es können Winkelaufleger 15 vorgesehen sein, die der Reduzierung der Auflagehöhe um die Dicke des Auflegerahmens 1 bei Verwendung der Untermatratze zum Einlegen in ein Bett oder in eine Liege dienen.1 shows a first embodiment of the invention in a longitudinal cross section. It shows a support frame 1 with a receiving bore 2, in which a lower telescopic sleeve 3 is arranged on fastening screws 8. In the lower telescopic sleeve there is an adjusting nut 6 with bowl holes 7. Furthermore, the sleeve has an internal thread 4 and an inward-pointing bend 5, which an upper telescopic sleeve 9 on its outward-facing bend 10 by the setting pressure of a compression spring 14 in its movement locked upwards so that the total spring travel is determined by the height of the upper telescopic sleeve. On the surface of the telescopic sleeve there are fastening screws 11 in the middle, which fix a cross member 13 via a rubber buffer 12. The compression spring 14 is pretensioned at the key holes 7 with a suitable key. Angle supports 15 can be provided, which serve to reduce the support height by the thickness of the support frame 1 when using the base mattress for insertion in a bed or in a couch.

Eine Weiterbildung der Erfindung ist in den Fig. 2 und 3 dargestellt. In einem Auflegerahmen 16 befindet sich die Aufnahmebohrung 17 für die Federhülse 18 und ein Innengewinde 19, in dem die Einstellmutter 20 mit Schlüssellöchern 21 und Gewinde 22 in der Höhe verstellt werden kann. Auf der Einstellmutter 20 ruht die Druckfeder 29 und ist mit einer Isolierscheibe 30 abgedeckt und mit dem Querträger durch Befestigungsklammern 31' verbunden. Der Querträger 31 weist hinter der Druckfeder eine Bohrung 27 auf, auf welcher ein Halteknopf 28 mit einer Schelle 26 und einem Haltering 26' angeordnet sind. Durch den Haltering 26' läuft ein Haltestrang 25. Vom Halteknopf 28 ist zu beiden Seiten ein weiterer Haltestrang 25' zu einem zwischen zwei Querträgern 31 vorgesehenen Haltepunkt 35 angeordnet. Der Haltestrang 25 ist an der Halterung des Bolzens 23 der Verstellschraube 23' befestigt. Mit dieser kann über die Gewindebohrung 24 einer feststehenden Mutter 34 sowohl die Höhe gewählt als auch die Sicherung gegen seitliches Verschieben der Querträger vorgenommen werden. Der Vorteil dieser Anordnung besteht darin, daß der Querträger durch Direkteinwirkung der Druckfedern 29 auch um seine Querachse sich den anatomisch verschiedenen Druckbelastungen anpaßt. Durch die Anordnung der Haltestränge werden die Querträger 31 axial durch die Halteknöpfe 36 zentriert. Durch Verwendung einer Gurthalterung wird eine Längs- und Querverschiebung der Querträger vollständig vermieden.A further development of the invention is shown in FIGS. 2 and 3. In a support frame 16 is the receiving bore 17 for the spring sleeve 18 and an internal thread 19 in which the adjusting nut 20 with key holes 21 and thread 22 can be adjusted in height. The compression spring 29 rests on the adjusting nut 20 and is covered with an insulating washer 30 and connected to the cross member by fastening clips 31 '. The cross member 31 has a bore 27 behind the compression spring, on which a holding button 28 with a clamp 26 and a retaining ring 26 'are arranged. A holding strand 25 runs through the holding ring 26 '. From the holding button 28, a further holding strand 25' is arranged on both sides to a holding point 35 provided between two cross members 31 arranges. The holding strand 25 is attached to the holder of the bolt 23 of the adjusting screw 23 '. With this, both the height can be selected and the securing against lateral displacement of the crossbeam can be made via the threaded bore 24 of a fixed nut 34. The advantage of this arrangement is that the cross member adapts to the anatomically different pressure loads by direct action of the compression springs 29 also about its transverse axis. Due to the arrangement of the holding strands, the cross members 31 are axially centered by the holding buttons 36. By using a belt holder, longitudinal and transverse displacement of the cross beams is completely avoided.

In Fig. 4 wird gezeigt, wie die Querträger durch einen Doppelhaltegurt 39 mit Hilfe einer Abnähung 40 fixiert sind und über Gurtschlitze 41, die in den Auflegerahmen 1 eingelassen sind, geführt werden und mit einem Gurtfeststeller 42 in ihrer Federhöhe einstellbar sind. Durch diese Anordnung können sich die Querträger in der Liegestellung nicht verschieben und werden gleichzeitig konstant bei Nichtbelastung in einer Liegeebene gehalten. Durch diese Vorrichtung kann mit einer θrundeinstel lungein bestimmtes Körperauflagegewicht bei der Einstellung berücksichtigt werden, während die Feineinstellung der einzelnen Körperzonen an der Druckfeder 29 mittels der Einstellschraube 20 vorgenommen wird.In Fig. 4 it is shown how the cross members are fixed by a double tether 39 with the aid of a stitching 40 and are guided via belt slots 41 which are embedded in the support frame 1 and are adjustable in their spring height with a belt lock 42. This arrangement means that the crossbeams cannot move in the lying position and are simultaneously held in a lying level when not in use. By means of this device, a specific body support weight can be taken into account with the adjustment with a basic adjustment, while the fine adjustment of the individual body zones on the compression spring 29 is carried out by means of the adjusting screw 20.

Die seitliche Verschiebung der Querträger wird durch ebenfalls einstellbare Gummigurte 43, die an Halterungen 44 der Querträger 31 befestigt und über Gummigurtschlitze 45 geführt sind, an Gummigurtfeststellern 46 fixiert. Diese Anordnung hat den Vorteil, daß bei Druckbelastungen bei seitlichen Schubwirkungen jeweils der Gegengurt in Aktion tritt und den Querträger auch bei Belastung in dieser Richtung stablilisiert.The lateral displacement of the crossbeams is also fixed to rubberbelt arrestors 46 by rubber straps 43 which are also adjustable and which are fastened to brackets 44 of the crossbeams 31 and are guided via rubber belt slots 45. This arrangement has the advantage that, in the event of pressure loads in the event of lateral thrust effects, the opposite belt comes into action and stabilizes the cross member even in this direction when loaded.
