Ein Nachteil dieses bekannten Lattenrostes besteht darin, daß er aufgrund der Anordnung des relativ platzaufwendigen Verstellantriebes klobig und damit optisch unschön wirkt.A disadvantage of this known slatted base is that it looks clunky and thus visually unattractive due to the arrangement of the relatively space-consuming adjustment.
Ein weiterer Nachteil besteht darin, daß der Lattenrost mit dem Verstellantrieb eine erhebliche Bauhöhe aufweist. Dies erschwert den Transport und die Handhabung des Lattenrostes.Another disadvantage is that the slatted frame with the adjustment has a considerable height. This complicates the transport and handling of the slatted base.

Der Erfindung liegt die Aufgabe zugrunde, eine Stützeinrichtung der im Oberbegriff des Anspruchs 1 genannten Art anzugeben, die optisch vorteilhaft gestaltet ist und einfach und kostengünstig herstellbar ist.The invention has for its object to provide a support means referred to in the preamble of claim 1, which is optically advantageous and is simple and inexpensive to produce.
Diese Aufgabe wird durch die im Anspruch 1 angegebene Erfindung gelöst.This object is achieved by the invention defined in claim 1.
Auf diese Weise ist der Antrieb bei einer als Lattenrost ausgebildeten Stützeinrichtung unmittelbar unterhalb der Latten angeordnet und tritt optisch in den Hintergrund, so daß der Lattenrost optisch vorteilhaft gestaltet ist.In this way, the drive is arranged in a trained as a slatted support means immediately below the slats and enters visually in the background, so that the slatted frame is optically advantageous.
Durch die Verwendung eines Linearantriebs ist zudem der Aufbau der erfindungsgemäßen Stützeinrichtung vereinfacht und damit kostengünstiger gestaltet.By using a linear drive, the structure of the support device according to the invention is also simplified and thus designed more cost-effective.
Ein besonderer Vorteil der erfindungsgemäßen Lehre besteht darin, daß durch die erfindungsgemäße Anordnung des Antriebs zwischen horizontalen Begrenzungsebenen des ersten Stützteiles und damit des Grundkörpers der Stützeinrichtung die Bauhöhe der Stützeinrichtung im Vergleich zu herkömmlichen, nicht verstellbaren Stützeinrichtungen nicht oder nur geringfügig vergrößert ist. Damit ist die erfindungsgemäße Stützeinrichtung auch bei filigran wirkenden Möbelstücken einsetzbar, ohne daß deren optischer Eindruck nachteilig beeinflußt wird.A particular advantage of the teaching of the invention is that the height of the support device is not or only slightly increased by the inventive arrangement of the drive between horizontal boundary planes of the first support member and thus of the base body of the support device compared to conventional non-adjustable support means. Thus, the support device according to the invention can also be used in filigree furniture without their optical impression is adversely affected.
Aufgrund der geringen Bauhöhe der Stützeinrichtung, mit dem Antrieb ermöglicht die erfindungsgemäße Lehre auch erstmals die Integration des Lattenrostes mit einer Matratze zu einer Einheit. Eine solche Integration ist bei motorisch verstellbaren Stützeinrichtungen gemäß dem Stand der Technik wegen der sich dann ergebenden Bauhöhe nicht möglich.Due to the low height of the support means, with the drive, the teaching of the invention also allows for the first time the integration of the slatted frame with a mattress to a unit. Such integration is not possible with motor-adjustable support devices according to the prior art because of the resulting height.
Die erfindungsgemäße Stützeinrichtung ist robust im Aufbau, langlebig und vielfältig einsetzbar.The support device according to the invention is robust in construction, durable and versatile.
Eine andere Ausführungsform der erfindungsgemäßen Lehre sieht vor, daß der Antrieb lösbar mit dem ersten Stützteil, insbesondere mit einem der Längsholme, verbunden ist. Dies erhöht die Wartungsfreundlichkeit der erfindungsgemäßen Stützeinrichtung, da beispielsweise ein defekter Antrieb in einfacher Weise austauschbar ist .Another embodiment of the teaching according to the invention provides that the drive is releasably connected to the first support member, in particular with one of the longitudinal beams connected. This increases the ease of maintenance of the support device according to the invention, since, for example, a defective drive is easily replaceable.
Der Antrieb ist zweckmäßigerweise zwischen seitlichen Begrenzungsebenen des ersten Stützelementes angeordnet. Bei dieser Ausführungsform steht der Antrieb auch seitlich nicht über die Stützeinrichtung hervor und ist damit vollständig in dessen Grenzen aufgenommen.The drive is expediently arranged between lateral boundary planes of the first support element. In this embodiment, the drive is also not laterally on the support means and is thus completely absorbed within its limits.
Bei den Ausführungsformen, bei denen der Antrieb nicht in einem der Längsholme des ersten Stützteiles aufgenommen ist, kann der Antrieb in einem Gehäuse aufgenommen sein, wie dies eine andere Ausführungsform vorsieht. Auf diese Weise ist der Antrieb bei der Handhabung oder dem Transport der Stützeinrichtung vor Beschädigungen geschützt.In the embodiments in which the drive is not accommodated in one of the longitudinal struts of the first support member, the drive may be accommodated in a housing, as provided for by another embodiment. In this way, the drive during handling or transport of the support device is protected from damage.
Das Gehäuse kann bei der vorgenannten Ausführungsform an einem mit dem ersten Stützteil verbundenen separaten Halteteil gehalten sein. Zweckmäßigerweise ist das Gehäuse jedoch mit einem der Längsholme und/oder einem Querholm des ersten Stützteiles verbunden ist. Dies erleichtert die Befestigung des Gehäuses und vereinfacht den Aufbau.In the aforementioned embodiment, the housing may be held on a separate holding part connected to the first support part. Conveniently, however, the housing is connected to one of the longitudinal members and / or a cross member of the first support member. This facilitates the attachment of the housing and simplifies the structure.
Grundsätzlich ist es ausreichend, daß in jedem Gehäuse ein einzelner Antrieb angeordnet ist. Entsprechend den jeweiligen Anforderungen können jedoch in dem Gehäuse zwei Antriebe angeordnet sein, derart, daß ein Doppelantrieb gebildet ist. Bei dieser Ausführungsform kann beispielsweise ein Linearantrieb zum Verschwenken eines Beinstützteiles und der andere zum Verschwenken eines Oberkörperstützteiles dienen.In principle, it is sufficient that a single drive is arranged in each housing. According to the respective requirements, however, two drives can be arranged in the housing, such that a double drive is formed. In this embodiment, for example, a linear drive for pivoting a leg support part and the other serve for pivoting a upper body support member.
Gemäß einer anderen Ausführungsform weist das erste Stützteil zwei in Querrichtung der Stützeinrichtung zueinander beabstandete Längsholme auf, wobei jedem Längsholm ein Gehäuse zugeordnet ist, in dem wenigstens ein Antrieb aufgenommen ist.According to another embodiment, the first support part has two longitudinal spars spaced apart from one another in the transverse direction of the support device, wherein each longitudinal rail is assigned a housing in which at least one drive is accommodated.
Vorteilhafterweise ist das Abtriebsorgan des Antriebs im wesentlichen in Längsrichtung der Stützeinrichtung beweglich. Auf diese Weise ist zum Verschwenken eines Stützteiles nur ein einfacher Schwenkmechanismus erforderlich, beispielsweise ein einfacher Schwenkhebel.Advantageously, the output member of the drive is movable substantially in the longitudinal direction of the support means. In this way, only a simple pivot mechanism is required for pivoting a support member, such as a simple pivot lever.
Der Antrieb ist erfindungsgemäß ein Linearantrieb. Linearantriebe bestehen als einfache und kostengünstige Standardbauteile zur Verfügung. Darüber hinaus sind mit Linearantrieben hohe Kräfte aufbringbar, so daß eine Verstellung der Stützeinrichtung auch unter hoher Last ohne weiteres möglich ist.The drive is according to the invention a linear drive. Linear actuators are available as simple and inexpensive standard components. In addition, high forces can be applied with linear drives, so that an adjustment of the support means is readily possible, even under high load.
Zweckmäßigerweise ist das Abtriebsorgan des Linearantriebs eine Spindelmutter, die verdrehsicher und in Schraubrichtung beweglich auf einer von dem Elektromotor drehantreibbaren Gewindespindel gehalten ist, wobei die Spindelmutter in Wirkungsverbindung mit einem Schwenkmechanismus steht zum Verschwenken wenigstens eines der Stützteile relativ zu dem ersten Stützteil. Eine derartige Anordnung ist einfach und robust im Aufbau.Conveniently, the output member of the linear drive is a spindle nut, which is held against rotation and movable in the screw on a rotatably driven by the electric motor threaded spindle, wherein the spindle nut is in operative connection with a pivot mechanism for pivoting at least one of the support members relative to the first support part. Such an arrangement is simple and robust in construction.
Eine andere vorteilhafte Weiterbildung der erfindungsgemäßen Lehre sieht vor, daß die Gewindespindel im wesentlichen parallel zu der Abtriebswelle des Elektromotors angeordnet ist und mit dieser über ein Getriebe in Antriebsverbindung steht. Auf diese Weise ist der Platzbedarf des Linearantriebs in Richtung der Gewindespindel verringert. Beispielsweise können die Abtriebswelle und die Gewindespindel übereinander oder nebeneinander angeordnet sein.Another advantageous development of the teaching of the invention provides that the threaded spindle is arranged substantially parallel to the output shaft of the electric motor and is in drive connection with this via a transmission. In this way, the space requirement of the linear drive is reduced in the direction of the threaded spindle. For example, the output shaft and the threaded spindle can be arranged one above the other or side by side.
Grundsätzlich ist es ausreichend, wenn die erfindungsgemäße Stützeinrichtung aus zwei zueinander verstellbaren Stützteilen besteht. Bei dieser Ausführungsform besteht die Verstellmöglichkeit dann beispielsweise darin, die Neigung eines Bettes im Bereich des Oberkörpers einer auf dem Bett liegenden Person zu verstellen. Es ist jedoch vorteilhaft, wenn die Stützeinrichtung mehr als zwei Stützteile aufweist. Hierzu sieht eine Ausführungsform vor, daß das erste Stützteil durch ein mittleres Stützteil und das zweite Stützteil durch ein Oberkörperstützteil gebildet ist und daß ein Beinstützteil vorgesehen ist, das mit dem mittleren Stützteil auf dessen dem Oberkörperstützteil abgewandter Seite gelenkig und um eine zur Schwenkachse des Oberkörperstützteiles parallele Schwenkachse verschwenkbar verbunden ist. Bei dieser Ausführungsform ist nicht nur die Neigung des Oberkörperstützteiles relativ zu dem mittleren Stützteil, sonden auch die Neigung des Beinstützteiles relativ zu dem mittleren Stützteil verstellbar. Auf diese Weise sind die Verstellmöglichkeiten erweitert, so daß die Anpassung der Stützeinrichtung an die Sitz- oder Liegeposition einer auf einer mit der Stützeinrichtung abgestützten Matratze ruhenden Person verbessert ist.In principle, it is sufficient if the support device according to the invention consists of two mutually adjustable support parts. In this embodiment, the adjustment is then, for example, to adjust the inclination of a bed in the region of the upper body of a person lying on the bed. However, it is advantageous if the support means has more than two support parts. For this purpose, an embodiment provides that the first support member is formed by a central support member and the second support member by an upper body support member and that a leg support member is provided, the articulated with the middle support member on the upper body support member side and a parallel to the pivot axis of the upper body support member Swivel axis is pivotally connected. In this embodiment, not only the inclination of the upper body support member relative to the central support member, but also the inclination of the leg support member relative to the central support member is adjustable. In this way, the adjustment options are expanded, so that the adaptation of the support means to the sitting or lying position of a supported on a support mattress is improved.
Eine Weiterbildung der vorgenannten Ausführüngsform sieht vor, daß ein Kopfstützteil vorgesehen ist, das mit dem Oberkörperstützteil auf dessen dem mittleren Stützteil abgewandter Seite gelenkig und um eine zur Schwenkachse des Oberkörperstützteiles im wesentlichen parallele Schwenkachse verschwenkbar verbunden ist. Hierdurch ist eine Verstellung der Stützeinrichtung im Kopfbereich ermöglicht.A development of the aforementioned Ausführüngsform provides that a headrest part is provided which is pivotally connected to the upper body support member on its side facing away from the central support member and pivotable about a pivot axis of the upper body support member substantially parallel pivot axis. As a result, an adjustment of the support device in the head area is possible.
Eine andere vorteilhafte Weiterbildung der vorgenannten Ausführungsformen sieht vor, daß ein Wadenstützteil vorgesehen ist, das mit dem Beinstützteil auf dessen dem mittleren Stützteil abgewandter Seite gelenkig und um eine zur Schwenkachse des Beinstützteiles im wesentlichen parallele Schwenkachse verschwenkbar verbunden ist. Bei dieser Ausführungsform ist zusätzlich eine Verstellung der Stützeinrichtung im Wadenbereich ermöglicht.Another advantageous development of the aforementioned embodiments provides that a calf support member is provided which is pivotally connected to the leg support member on its side facing away from the central support member and pivotable about a substantially parallel to the pivot axis of the leg support member pivot axis. In this embodiment, an adjustment of the support device in the calf area is also possible.
