Description
Die Erfindung betrifft einen verstellbaren Bettrost gemäß dem Oberbegriff des ersten Patentanspruches.The invention relates to an adjustable bed frame according to the preamble of the first Claim.
Es ist eine Vorrichtung zum Verschwenken von Hochstellteilen an Matratzenrahmen bekannt, DE-A-24 20 598, die über Verstelihebel verfügt, welche unterhalb des Innenrahmens an diesem anliegen, wobei die Verstellhebel über eine gemeinsame Antriebswelle miteinander verbunden sind, an der ein Hebelarm verdrehfest angeordnet ist, der über ein stangenförmiges Kupplungselement mit dem Verstellantrieb verbunden ist, welcher seinerseits gelenkig an einer im Rahmen festgelegten Querachse angeordnet ist.It is a device for pivoting raised parts on mattress frames known, DE-A-24 20 598, which has an adjusting lever which is below the inner frame abut against this, the adjustment lever via a common Drive shaft are connected to each other, on which a lever arm is arranged non-rotatably is that via a rod-shaped coupling element with the adjustment drive is connected, which in turn is articulated on a transverse axis defined in the frame is arranged.
Nachteilig an dieser vorbekannten Konstruktion ist, daß sie sehr aufwendig ausgebildet ist und viele unterschiedliche Bauteile benötigt, daß in der Antriebswelle für die Verstellhebel bei ungleicher Belastung der Liegefläche sehr starke Torsionsmomente auftreten können, so daß entweder die Antriebswelle relativ massiv und schwer ausgebildet sein muß oder aber der Innenrahmen des Bettrostes, da sich dieser bei einer einseitigen Belastung sonst sehr stark verwinden würde. Weiterhin erfordert das massive Kupplungselement zur Erzeugung einer Hub- und Schubbewegung das Vorhandensein von mechanisch aufwendig herzustellenden Gewindespindeln oder Spindelmuttern, so daß der gesamte Verstellmechanismus extrem fertigungs- und kostenintensiv und wenig flexibel ausgebildet ist.A disadvantage of this known construction is that it is very complex is and requires many different components that in the drive shaft for the Adjusting lever with uneven loading of the lying surface very strong torsional moments can occur so that either the drive shaft is relatively solid and heavy must be or the inner frame of the bed frame, as this is in a otherwise one-sided stress would twist very much. This also requires massive coupling element for generating a lifting and pushing movement the presence of mechanically complex to produce threaded spindles or Spindle nuts so that the entire adjustment mechanism is extremely manufacturing and is expensive and not very flexible.
Weiterhin ist ein verstellbarer Bettrost bekannt, US-A-4 095 296, der ein Zugmittel zur Kraftübertragung, insbesondere aber zur Kraftumlenkung nutzt, wozu dieses Zugmittel auch nicht durch Aufwickeln verkürzt wird, sondem ständig die gleiche Länge behält. Der Bettrost weist einen Verstellantrieb auf, der zur Winkelanpassung verschwenkbar in einem Bettrahmen angelenkt sein muß, da er mechanisch über einen aufwendigen Spindelantrieb direkt an einem Hebelarm eines Verstellhebels angreift. Dieser Verstellhebel ist unmütelbar unter einem Innenrahmen befestigt und über eine Schweißkonstruktion mit einem Querrohr und dem Hebelarm verbunden. Furthermore, an adjustable bed frame is known, US-A-4 095 296, which is a traction means used for power transmission, but especially for power redirection, for what this Traction means is not shortened by winding, but always the same Retains length. The bed frame has an adjustment drive for angle adjustment must be pivoted in a bed frame because it is mechanically over a complex spindle drive directly on a lever arm of an adjustment lever attacks. This adjustment lever is fastened firmly and under an inner frame connected to a cross tube and the lever arm via a welded construction.
Eine Schwenkbewegung eines Verstellhebels kann nur gleichzeitig um die Schwenkachse der Rostteile erfolgen, wobei deren Gelenke aufgrund der ungünstigen Hebelwirkungen große Querkräfte ertragen müssen. Auch diese bekannte Verstelleinrichtung ist damit sehr kompliziert, aufwendig und kostenintensiv ausgeführt.A pivoting movement of an adjustment lever can only be carried out simultaneously around the pivot axis of the grate parts, their joints due to the unfavorable leverage have to endure large lateral forces. This well-known adjustment device is very complicated, time-consuming and costly.
Eine andere bekannte Vorrichtung, US-A-4 225 988, weist zum Wenden einer in einem Bett liegenden Person eine Mechanik auf, bei der über eine unterhalb eines Längsholmes eines Bettrahmens verlaufende Welle mit einem Handrad ein Kabel aufwickelbar ist, welches an einer Hebelmechanik angreift, welche ebenfalls direkt unterhalb eines verschwenkbaren Seitenteils mit diesem verschraubt ist. Eine funktionsiüchtige Verstellung von Rücken- oder Fußteilen lässt sich mit einer solchen Vorrichtung nicht verwirklichen, wie auch die höchst komplizierte Rücken- und Fußteilverstellung der gleichen Veröffentlichung zeigt.Another known device, US-A-4,225,988, has one to turn in one Person lying on a mechanism on which one is below a bed Longitudinal spar of a bed frame running shaft with a handwheel a cable can be wound up, which engages a lever mechanism, which also directly is screwed to this below a pivotable side part. A functional one Adjustment of back or foot parts can be done with such a device not realize, like the highly complicated back and foot part adjustment the same publication shows.
Bekannt ist weiterhin eine über Ketten betriebene Kopf- und Fußteilverstellung eines Bettes, US-A-1 658 776, die ebenfalls nicht verkürzt werden, sondern die über einen Spindelantrieb Kurvenscheiben bewegen, an denen sich nach oben erstreckende Streben angeordnet sind, die gelenkig mit den Kopf- und Fußteilen verbunden sind. Auch diese Ausführungsform eines verstellbaren Bettrostes benötigt mehrere aufwendige Bauteile und erforderte einen erhöhten Fertigungsaufwand.A head and foot part adjustment operated via chains is also known Bettes, US-A-1 658 776, which are also not shortened, but rather over one Spindle drive to move cam discs on which extend upwards Struts are arranged, which are articulated to the head and foot parts. This embodiment of an adjustable bed frame also requires several complex ones Components and required an increased manufacturing effort.
Aufgabe der Erfindung ist es, einen elektromotorisch verstellbaren Bettrost zur Verfügung zu stellen, der einfach und aus wenigen Bauteilen aufgebaut und kostengünstig herzustellen ist.The object of the invention is to provide an electromotively adjustable bed frame to provide the simple and made up of a few components and inexpensive is to be produced.
Zur Lösung dieser Aufgabe wird von einem verstellbaren Lattenrost der im Patentanspruch
1 genannten gattungsgemäßen Art ausgegangen, welcher erfindungsgemäß
die im kennzeichnenden Teil desselben aufgeführten Merkmale aufweist.To solve this problem is of an adjustable slatted frame in the
Dadurch, daß das Kupplungselement für jeden Verstellhebel aus einem Zugmittel besteht, welches auf einer vom Verstellantrieb angetriebenen Welle aufgewickelt werden kann, ergeben sich wesentliche Vorteile gegenüber den vorbekannten Vorrichtungen. Der Verstellantrieb kann beispielsweise rahmenfest an einem der Längsoder Querholme befestigt werden, ohne daß er schwenkbar gelagert sein muß, um einen Winkelversatz eines eine massive Schub- oder Druckstange bewegenden Antriebes auszugleichen. Weiterhin entfällt aufgrund der fehlenden Antriebswelle der Verstellhebel auch die Torsionsbelastung der Antriebswelle, wobei die vom Verstellantrieb angetriebene Welle einen solch geringen Durchmesser aufweist, daß das darauf aufgewickelte Zugmittel nur einen sehr geringes Drehmoment auf die Welle ausüben kann. Ein weiterer Vorteil dieses verstellbaren Bettrostes besteht darin, daß das Zugmittel entsprechend der geforderten Länge einfach abzulängen ist, so daß der Abstand von Verstellantrieb zum Verstellhebel frei wählbar ist. Gleichzeitig weist diese erfinderische Konstruktion nur ein sehr geringes Gewicht auf und benötigt keine aufwendigen Beschläge zur Befestigung an einem Rahmen, so daß dieser Verstellmechanismus auch auf einfachste Art und Weise an bestehenden Bettrosten nachgerüstet werden kann. Dazu kann die Welle zum Aufwickeln des Zugmittels einfach der Innenbreite eines Bettrahmens angepaßt werden, so daß die erfinderische Konstruktion auch vollkommen unabhängig von der Breite eines Bettrahmens ist. Zudem besitzt diese Konstruktion eine sehr geringe Bauhöhe, so daß sich die Transportkosten der fertigen Bettroste gegenüber anderen elektromotorisch verstellbaren Bettrosten deutlich reduziert.Characterized in that the coupling element for each adjusting lever from a traction device exists, which is wound on a shaft driven by the adjustment drive can be, there are significant advantages over the previously known devices. The adjustment drive can, for example, be fixed to the frame on one of the longitudinal or Crossbars are attached without it having to be pivoted to an angular offset of a drive moving a massive push or push rod compensate. Furthermore, due to the missing drive shaft, the Adjustment lever also the torsional load on the drive shaft, being that of the adjustment drive driven shaft has such a small diameter that the traction means wound thereon have very little torque on the shaft can exercise. Another advantage of this adjustable bed base is that the traction means can be easily cut to length, so that the distance from the adjustment drive to the adjustment lever can be freely selected. At the same time this inventive construction is very light and does not require any elaborate fittings for attachment to a frame, so that this adjustment mechanism also in the simplest way on existing bed frames can be retrofitted. The shaft can be used to wind up the traction device simply be adjusted to the inside width of a bed frame, so that the inventive Construction also completely independent of the width of a bed frame is. In addition, this construction has a very low profile, so that the Transport costs of the finished bed frames compared to other electric motor adjustable Bed rust significantly reduced.
Die Konstruktion ist dabei nicht auf Bettroste mit Latten beschränkt, sondern kann auch bei Bettrosten mit separaten Rostflächen, die beispielsweise mit einzelnen Federelementen bestückt sind, Verwendung finden.The construction is not limited to bed slats with slats, but can also for bed gratings with separate grate surfaces, for example with individual spring elements are equipped, find use.
Weitere vorteilhafte Ausgestaltungen des Gegenstandes der Erfindung ergeben sich aus und in Kombination mit den weiteren Unteransprüchen.Further advantageous configurations of the subject matter of the invention result from and in combination with the other subclaims.
Gemäß einer besonders bevorzugten Ausführungsform des Gegenstandes der Erfindung ist der Verstellantrieb an einem Längsholm rahmenfest angeordnet und das Zugmittel als einfaches Gurt- oder Flechtband mit hoher Zugfestigkeit ausgebildet.According to a particularly preferred embodiment of the subject of the invention the adjustment drive is fixed to the frame on a longitudinal beam and that Traction means designed as a simple belt or braid with high tensile strength.
Als Zugmittel können ebenfalls Federstahlbänder oder kettenförmige Gebilde verwendet werden. Ein solches Band läßt sich dann unmittelbar auf der Welle oder auf einem separaten Aufrollsegment, welches zusätzlich mit seitlichen Führungen versehen sein kann, lagenförmig auf der Welle zu einer Rolle aufwickeln. Vorteilhaft ist ebenfalls, daß der Verstellantrieb auch extern an einem Bettgestell oder einem Bettkasten angeordnet werden kann, so daß unabhängig von der Bauart eines Bettes eine optimale Plazierung möglich wird. Spring steel strips or chain-like structures can also be used as traction means become. Such a band can then be placed directly on the shaft or on a separate roll-up segment, which also has side guides can be wound in a layer on the shaft to form a roll. It is advantageous also that the adjustment drive is also external to a bed frame or a bed box can be arranged so that regardless of the design of a bed optimal placement becomes possible.
Gemäß einer anderen vorteilhaften Ausführungsform des Gegenstandes der Erfindung ist das Zugmittel als einfaches, im Querschnitt rundes Seil, Drahtseil oder Kunststoffseil ausgebildet. Bevorzugterweise wird dazu ein Drahtseil mit einer Kunststoffbeschichtung verwendet, so daß bei einer hohen Biegefähigkeit die Verletzungsgefahr an dem Kunststoffdrahtseil ebenso wie der Verschleiß minimiert wird. Weiterhin wirkt sich dies auf eine gleichmäßigeres Aufwickeln auf einem als Aufwickelvorrichtung ausgebildeten Bereich der vom Verstellantrieb angetriebenen Welle aus, in dem ein Ende des Zugmittels festgelegt ist, welches durch Drehung um die Welle auf dieser aufgewickelt wird. Durch eine vorteilhafte, in einer leicht von der rein radialen Richtung abweichend eingebrachten Ausnehmung zur Aufnahme des Endes eines Drahtseiles erhält das Zugmittel eine seitliche Anfangsausrichtung, so daß sich beim Aufwickeln alle folgenden Windungen nebeneinander anordnen.According to another advantageous embodiment of the subject of the invention is the traction device as a simple rope, wire rope or round in cross section Plastic rope formed. For this purpose, a wire rope with a plastic coating is preferably used used, so that the risk of injury with a high flexibility on the plastic wire rope as well as wear is minimized. Farther this affects a more uniform winding on as a winder trained area of the shaft driven by the adjusting drive, in which one end of the traction means is fixed, which by rotating around the shaft this is wound up. By an advantageous, in a slightly different from the purely radial Direction of recess made to accommodate the end of a Wire rope receives the traction device a lateral initial orientation, so that when Place all subsequent turns next to each other.
Vorteilhaft ist eine Ausführungsform, bei der auf der Welle ein kreiszylindrisches Aufrollsegment angeordnet ist, welches eine schraubenförmige Ringnut zur Aufnahme des Zugmittels aufweist, so daß die gewünschte geordnete Form des Aufwickelns des Drahtseiles auf der Welle bzw. dem Aufrollsegment weiter unterstützt wird.An embodiment is advantageous in which a circular cylindrical on the shaft Rollup segment is arranged, which has a helical annular groove for receiving of the traction means, so that the desired orderly form of winding of the wire rope on the shaft or the reel segment is further supported.
Von besondere Bedeutung ist weiterhin, daß die für die verschiedenen Zugmittel jeweils verwendeten Aufrollsegmente unterschiedliche Außendurchmesser aufweisen können, so daß durch ihren Austausch eine einfache und schnelle Variation in der Bewegungsgeschwindigkeit bzw. der Zugkraft möglich ist, ohne daß weitere Änderungsmaßnahmen am Verstellantrieb erforderlich werden. Somit läßt sich der Verstellantrieb optimal an alle bestehenden Größen und Abmessungen der unterschiedlichsten Bettroste anpassen.It is also of particular importance that each for the different traction means used roll segments have different outer diameters can, so that a simple and quick variation in the Movement speed or the tractive force is possible without further change measures on the actuator. The adjustment drive can thus be operated optimal to all existing sizes and dimensions of the most varied Adjust bed slats.
Eine besonders vorteilhafte Ausführungsform weist als Antrieb einen in einem Rohr angeordneten Elektromotor, ähnlich einem Rolladenantrieb, auf, auf dem das Zugmittel aufgewickelt wird.A particularly advantageous embodiment has a drive in a tube arranged electric motor, similar to a roller shutter drive, on which the traction device is wound up.
Das Zugmittel greift bevorzugterweise am Ende des Hebelarmes an, welcher als Funktionseinheit mit dem Verstellhebel, insbesondere einteilg, ausgebildet ist, wobei die Wirkungslinie der Kraft durch das Zugmittel und unterhalb der Schwenklagerung des Verstellhebels verläuft, so daß keine seitlichen wirkenden Kräfte oder Momente in dem gesamten Mechanismus erzeugt werden, die sich nachteilig auf dessen Funktion und Dauerhaltbarkeit auswirken könnten. The traction means preferably acts on the end of the lever arm, which as Functional unit with the adjusting lever, in particular one part, is formed, wherein the line of action of the force through the traction device and below the pivot bearing of the adjustment lever runs so that no lateral forces or moments generated in the entire mechanism, which adversely affects its Function and durability could affect.
Vorteilhaft ist ebenfalls eine Ausführungsform der Erfindung, deren Verstellantrieb zur Verschwenkung eines Fuß- und eines Rückenteils wahlweise zwei Wellen gleichzeitig oder unabhängig voneinander einzeln antreibt, so daß kein zweiter Motor zum Verschwenken eines zweiten Rahmenteils notwendig ist. Hierzu ist der Verstellantrieb mit einer entsprechenden Kupplung ausgestattet.Also advantageous is an embodiment of the invention, the adjustment drive for swiveling a foot and a back part optionally two shafts at the same time or drives independently of each other, so that no second motor to Swiveling a second frame part is necessary. This is the adjustment drive equipped with a corresponding coupling.
