Abstract

An adjusting arrangement dispenses with the need for cable laying and wiring. Furthermore, it does not require accessories in the form of fastening elements, and can therefore be easily manipulated by the user. The necessary drives for adjusting the foot-rest and head-rest of the bed are arranged in a box-like housing (10). The adjusting spindles are connected to the opposing front faces of the housing (10). Guides for the adjusting screws (14) are formed on the inner faces of the housing (10). In addition, the housing (10) is provided with locking means for mounting the adjusting drives (11), which are controlled together or separately by a single control unit (24). This adjusting arrangement is particularly intended for beds in the domestic sector.

Description

Die vorliegende Erfindung betrifft eine Verstelleinrichtung für einen mit mindestens einem schwenkbaren Rückenteil und einem schwenkbaren Fußteil ausgerüsteten Lattenrost eines Bettes, bei der das Rücken- und das Fußteil jeweils durch einen elektromotorischen Stelltrieb verstellbar sind, der jeweils eine Stellspindel und eine darauf aufgeschraubte Stellmutter aufweist, wobei die Stelltriebe in einem kastenartigen, durch einen Deckel verschließbaren Gehäuse (10) angeordnet sind, daß die Stellspindeln einander gegenüberliegend den Stirnwänden des Gehäuses zugeordnet sind, und bei der die Stelltriebe mittels einer im Gehäuse montierten Steuereinheit gemeinsam oder unabhängig voneinander betätigbar sind.The present invention relates to an adjustment device for one with at least one pivotable Back part and a swivel foot part equipped slatted frame of a bed, in which the back and the foot part are each adjustable by an electromotive actuator, each having an adjusting spindle and has an adjusting nut screwed thereon, the actuating drives in a box-like manner, through a Lid lockable housing (10) are arranged that the adjusting spindles opposite each other End walls of the housing are assigned, and in which the actuators are mounted in the housing Control unit can be operated together or independently of one another.

Bei einer aus dem DE-GM 87 11 657 bekannten Verstelleinrichtung dieser Art sind die auf die Stellspindeln aufgeschraubten Stellmuttern als Gabelkopf ausgebildet, um sie mit einem Hebel gelenkig zu verbinden, der drehfest auf die Horizontalachsen des Rücken- und des Fußteils aufgesetzt sind. Die Verbindung erfolgt durch Stifte. Außerdem sind zusätzliche Maßnahmen notwendig, um die Stelltriebe im Gehäuse lagegerecht zu fixieren.In an adjustment device of this type known from DE-GM 87 11 657, these are on the adjusting spindles screwed adjusting nuts designed as clevis to articulate with a lever that are rotatably attached to the horizontal axes of the back and foot sections. The connection is made by Pencils. In addition, additional measures are necessary to fix the actuators in the housing in the correct position.

Diese vorbekannte Verstelleinrichtung ist äußerst aufwendig, bedingt durch die Festlegung der Stelltriebe mittels geeigneter Befestigungselemente. Ein weiterer gravierender Nachteil ist noch darin zu sehen, daß für die Montage der Verstelleinrichtung am Lattenrost Stiftverbindungen erforderlich sind, die vom Benutzer normalerweise nicht hergestellt werden können, da die entsprechenden Werkzeuge im Haushalt nicht vorhanden sind. Deshalb ist die vorbekannte Verstelleinrichtung zur Nachrüstung eines vorhandenen Lattenrostes nicht geeignet.This known adjusting device is extremely complex, due to the setting of the actuators using suitable fasteners. Another serious disadvantage is the fact that for The assembly of the adjustment device on the slatted frame requires pin connections that are normally performed by the user cannot be produced because the corresponding tools are not available in the household are. Therefore, the previously known adjustment device for retrofitting an existing slatted frame is not suitable.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Verstelleinrichtung gemäß dem Oberbegriff des Anspruches 1 in konstruktiv einfacher Weise montagefreundlich in der Weise zu gestalten, daß weder für die Festlegung der Stelltriebe im Gehäuse Befestigungselemente noch für die Anbringung am Lattenrost Befestigungsteile notwendig werden.The present invention has for its object an adjusting device according to the preamble of claim 1 in a structurally simple manner easy to assemble in such a way that neither for the setting of the actuators in the housing fasteners still for attachment to the slatted frame fasteners become necessary.

Diese Aufgabe wird durch dem Gegenstand des Anspruchs 1 gelöst.This object is solved by the subject matter of claim 1.

Bei den verwendeten Stelltrieben handelt es sich um bekannte Linearantriebe. Da die im Betriebszustand auf die Stellspindeln aufgeschraubten Stellmuttern in Führungen gelagert sind, entfallen die ansonsten notwendigen Teile, um eine Drehung der Mutter zu verhindern. Außerdem werden die Befestigungsteile bzw. die Beschläge nur äußerst gering belastet, da der Kraftfluß ausschließlich durch das Gehäuse hindurch erfolgt. Daraus ergibt sich eine erhebliche Stabilisierung des Rahmens des Lattenrostes. Die Montage ist besonders einfach, da in den Seitenwänden des Gehäuses im Bereich der Stirnenden miteinander fluchtende Ausnehmungen vorgesehen sind, deren Grund als Halbkreis ausgebildet ist, daß in den Ausnehmungen die das Rücken- bzw. Fußteil tragenden Horizontalachsen eingelegt sind, und daß die die Ausnehmungen aufweisenden Bereiche der Seitenwände innenseitig horizontale Führungsnuten aufweisen, in die jeweils ein die Ausnehmungen bzw. die Horizontalachsen übergreifender, in der eingesteckten Stellung arretierter Schließer einführbar ist. Die Höhe der Ausnehmungen entspricht dem Durchmesser der Horizontalachsen, so daß diese formschlüssig in den Ausnehmungen festgelegt sind. Der Schließer verhindert in der montierten Stellung ein Herabfallen des Gehäuses. Der Hersteller des Lattenrostes braucht zur Montage der Verstelleinrichtung lediglich die Schließer soweit zu verschieben, daß die Ausnehmungen frei sind. Nach dem Anhängen des Gehäuses müssen lediglich die Schließer in die arretierte Betriebsstellung zurückgeschoben werden. Zum Anhängen sind deshalb weder Beschläge oder sonstige Befestigungsteile noch Werkzeuge erforderlich.The actuators used are known linear actuators. Because the in the operating state the adjusting nuts screwed onto the adjusting spindles are stored in guides, the otherwise necessary are not necessary Parts to prevent the nut from rotating. In addition, the fasteners and the Fittings are only subjected to extremely low loads, since the force flow occurs exclusively through the housing. This results in a considerable stabilization of the frame of the slatted frame. The assembly is special simply because recesses are flush with each other in the side walls of the housing in the area of the front ends are provided, the base of which is formed as a semicircle, that in the recesses Back or foot part bearing horizontal axes are inserted, and that the recesses Areas of the side walls have horizontal guide grooves on the inside, into each of which the recesses or the horizontal axes of the closer, which is locked in the inserted position can be introduced. The height of the recesses corresponds to the diameter of the horizontal axes, so that these are positively fixed in the recesses. The closer prevents in the assembled position Falling down the case. The manufacturer of the slatted frame only needs to assemble the adjustment device to move the closer so that the recesses are free. After attaching the case only the NO contacts have to be pushed back into the locked operating position. To attach therefore neither fittings or other fastening parts nor tools are required.

Zur Erhöhung der Versteifungs- und Verwindungsfestigkeit ist es zweckmäßig, wenn das Gehäuse Längs- und/oder Querversteifungsrippen aufweist. Da es am stärksten im Bereich der Beschlagaufnahmen belastet wird, ist in vorteilhafter Weise das Gehäuse in diesem Bereich doppelwandig ausgebildet und/oder mit Verstrebungen versehen. Das Gehäuse läßt sich in kostengünstiger Weise mit der notwendigen Festigkeit herstellen, wenn dieses aus einem hochbelastbaren, schlagfesten, flexiblen sowie unverformbaren Kunststoff gefertigt.To increase the stiffness and torsion resistance, it is useful if the housing and / or cross stiffening ribs. Since it is most heavily burdened in the area of the fittings is, the housing is advantageously double-walled in this area and / or with struts Mistake. The housing can be manufactured inexpensively with the necessary strength, if this is made of a heavy-duty, impact-resistant, flexible and non-deformable plastic manufactured.

Die Stelltriebe können mit der normalen Netzspannung, mit einer herabgesetzten Netzspannung oder mittels eines aufladbaren Akkumulators betrieben werden. Je nach Ausführung kann es kann notwendig werden, daß die Steuereinheit mit einem die Netzspannung herabsetzenden Transformator oder mit einem mittels eines Ladegerätes aufladbaren Akkumulator ausgerüstet istThe actuators can be operated with the normal mains voltage, with a reduced mains voltage or by means of a rechargeable battery can be operated. Depending on the version, it may be necessary that the control unit with a transformer reducing the mains voltage or with a means of Charger rechargeable battery is equipped

Das gewindefreie Teilstück der Stellmutter 14 ist im querschnitt U-förmig ausgebildet, wobei die offene Seite der Oberseite des Gehäuses 10 bzw. dem Deckel 30 zugewandt liegt und mit einer Führungsplatte 31 verschlossen ist. Das gewindefreie Teilstück der Stellmutter 14 ist zur Verstärkung mit innenliegenden Rippen versehen. Das dem Gewindeteil der Stellmutter 14 gegenüberliegende Ende ist durch eine Stirnwand 20 verschlossen. Die Außenfläche dieser Stirnwand 20 und das freie Ende des Winkelhebels 18 berühren sich. In der Fig. 1 ist die Horizontallage des Rücken- bzw des Fußteils 16 in Vollinien dargestellt. In dieser Stellung befindet sich die Stellmutter 14 in der linken Endstellung, d.h. dem Antriebsmotor 13 zugewandt. Durch das Eigengewicht des Fuß- bzw. Rückenteils 16 bleibt der Winkelhebel 18 ständig in Kontakt mit der Stellmutter 14. Die andere Endstellung der Stellmutter 14 ist mit 14' bezeichnet und in strichpunktierten Linien dargestellt. Auch die ausgeschwenkte Stellung des Fuß- bzw. des Rückenteils 16 und des Winkelhebels 18 ist in gleicher Weise dargestellt und durch die Bezugszeichen 16' bzw. 18' gekennzeichnet. Die Verstellung des Fuß- bzw. Rückenteils 16 erfolgt stufenlos. Oberhalb der Stellmutter 14 ist zur Verbesserung der Führung der Stellmutter 14 die Führungsplatte 31 mit dem Gehäuse 10 verschraubt Zwischen den Stirnenden des Deckels 30 und den Stirnenden des Gehäuses 10 sind die Seitenwände des Gehäuses 10 innenseitig mit auf gleicher Höhe liegenden Führungsnuten versehen, in die ein Schließer 21 eingeschoben ist. Dadurch wird die Horizontalachse 17 im Gehäuse 10 festgesetzt.For the sake of illustration, only part of a housing 10, in which two Actuators 11 designed as linear drives are arranged. 1 and 2, however, is only one actuator shown. The second actuator is arranged in mirror image.

Wird der Bedienungstaster S3 gedrückt, zieht das Relais K1 nicht an, da der obere Endschalter S 7 geöffnet ist. Wird der Bedienungstaster S4 gedrückt, zieht das Relais K2 an, da der untere Endschalter S8 noch geschlossen ist. Der Wechselkontakt des Relais K2 schaltet um, so daß der Motor M1 Spannung bekommt, d.h. zum Einfahren der Stellmutter 14 in Drehung versetzt wird. Der Motor M1 schaltet ab, sobald der Bedienungstaster S4 losgelassen wird, da das Relais K2 abfällt und die zugeordneten Kontakte geöffnet werden. Zwei weitere Kontakte schließen, um den Motor M1 generatorisch abzubremsen, wie noch näher bechrieben wird. Wird der Bedienungstaster S4 solange gedrückt, bis die Stellmutter 14 den Endschalter S8 betätigt, läuft der zuvor beschriebene Vorgang ebenfalls ab.The function of the motor M1 is described below. The function of the motor M2 is corresponding, so that the description is omitted. The drawing shows the drive motors 13 and M1, M2 with extended adjusting nuts 14. Relays K1, K2, control buttons S3, S4 and assigned the limit switches S7, S8. If the button S3 is pressed, the relay K1 does not pick up because the upper limit switch S 7 is open. If the control button S4 is pressed, the relay K2 picks up because the lower limit switch S8 is still closed. The changeover contact of the relay K2 switches, so that the motor M1 gets voltage, i.e. is rotated to retract the adjusting nut 14. The motor M1 switches as soon as the control button S4 is released, because the relay K2 drops out and the assigned contacts be opened. Close two more contacts to brake the motor M1 as a generator is described in more detail. The control button S4 is pressed until the adjusting nut 14 the limit switch When S8 is pressed, the process described above also takes place.

    Um das Fuß- bzw. Rückenteil 16 in jeder Lage zu halten, ist die Steuereinheit so ausgelegt, daß beim Stillstand des Motors oder beim Abschalten dieser stark elektrisch belastet wird, wodurch eine sofortige Abbremsung bzw. ein sofortiges Anhalten erreicht wird. Außerdem läßt sich die Motorwelle im Stillstand nur durch großen Kraftaufwand drehen. Dazu wird der Motor M1 durch die Relais K1, K2 mit den zugeordneten Wechselkontakten kurzgeschlossen.In order to keep the foot or back part 16 in any position, the control unit is designed such that when it is at a standstill of the motor or when it is switched off is subjected to a high electrical load, which results in immediate braking or an immediate stop is achieved.
