Abstract

The lifting device comprises essentially a flat, rigid frame suitable for wall fixing, formed by two longitudinally slotted vertical guide posts connected together at top and bottom by cross-struts. Within each guide post a screw-shaft spindle is set on bearings, and the two spindles can be driven in the same sense of rotation by a common motor. Two nuts placed above each other a certain distance apart run on each screw-shaft spindle and are guided along the slot in their respective post. A cantilever is attached to the pair of nuts in each guide post and projects from the plane of the frame. When a bed or other load is in a raised position, the space below it is left completely free and is freely accessible.

Description

Die Erfindung betrifft eine Hebevorrichtung, insbesondere für Betten, mit zwei vertikalen Führungssäulen in Form von längsgeschlitzten Hohlprofilen, je im Innern der Führungssäulen gelagerten, gemeinsam antreibbaren Gewindespindeln und durch den Längsschlitz jeder Führungssäule hindurch mit Spindelmuttern verbundenen, heb- und senkbaren Lastaufnahmeorganen.The invention relates to a lifting device, in particular for beds, with two vertical guide columns in the form of longitudinally slotted hollow profiles, threaded spindles mounted in the interior of the guide columns, and through the longitudinal slot of each guide column connected with spindle nuts, lifting and lowering load-bearing members.

Es sind bereits verschiedene Vorrichtungen vorgeschlagen worden, welche dazu dienen, ein Bett bei Nichtbenutzung gegen die Zimmerdecke anzuheben, um auf dem Boden Platz zu gewinnen. Manche dieser Vorschläge sehen aufwendige, im Bettgestell eingebaute Spezialantriebe vor (DE-A-37 36 012, DE-A-38 27 300), und eine weitere bekannte Vorrichtung weist vier Ecksäulen mit je einer Spindel auf, wobei alle Spindeln über Kegelzahnräder angetrieben sind (FR-A-2 584 283). Vor allem wegen den frei im Raum stehenden Säulen sind die praktische Anwendbarkeit und der Nutzen der genannten Vorrichtungen sehr in Frage gestellt.Various devices have been proposed which serve to lift a bed against the ceiling when not in use in order to gain space on the floor. Some of these proposals provide complex, special drives installed in the bed frame (DE-A-37 36 012, DE-A-38 27 300), and a further known device has four corner pillars, each with a spindle, all spindles being driven by bevel gearwheels (FR-A-2 584 283). Especially because of the free-standing columns, the practical applicability and the benefits of the devices mentioned are very much in question.

Eine Hebevorrichtung der eingangs genannten Art (zum Anheben von Fahrzeugen in Automobilwerkstätten) ist aus der US-A-1,497,046 bekannt. Bei dieser sind zwei freistehende, einzeln am Boden abgestützte Säulen vorhanden. Deren beide Gewindespindeln sind gemeinsam von Hand über Kegelradgetriebe und eine Zwischenwelle antreibbar. Dadurch ist in der einen Säule eine rechtsgängige und in der anderen Säule eine linksgängige Spindel mit entsprechender Mutter erforderlich. Zwei mit je einer Spindelmutter verbundene Fahrzeugrad-Aufnehmer befinden sich zwischen beiden Säulen.A lifting device of the type mentioned (for lifting vehicles in automobile workshops) is known from US-A-1,497,046. There are two free-standing columns, each supported on the floor. The two threaded spindles can be driven together by hand via bevel gear and an intermediate shaft. As a result, there is a right-handed spindle in one column and a left-handed spindle in the other column required with appropriate mother. Two vehicle wheel sensors, each connected to a spindle nut, are located between the two columns.

Aufgabe der vorliegenden Erfindung ist es, eine Hebevorrichtung zu schaffen, welche die erwähnten Mängel bekannter Vorrichtungen vermeidet und die insbesondere einfach zu montieren ist und eine praktisch vollständige, freie Nutzung des unter beispielsweise einem angehobenen Bett befindlichen Raumes zulässt.The object of the present invention is to provide a lifting device which avoids the above-mentioned shortcomings of known devices and which is particularly easy to assemble and permits practically complete, free use of the space under, for example, a raised bed.

Die erfindungsgemässe Hebevorrichtung, welche diesen Anforderungen gerecht wird, ist dadurch gekennzeichnet, dass die Führungssäulen mittels oberen und unteren Querverbindern zu einem ebenen, starren, für Wandbefestigung eingerichteten Rahmen verbunden sind, und dass an jeder Gewindespindel zwei im Abstand übereinander geführte Muttern laufen, an denen ein aus der Ebene des Rahmens herausragender Ausleger befestigt ist.The lifting device according to the invention, which meets these requirements, is characterized in that the guide columns are connected by means of upper and lower cross connectors to form a flat, rigid frame designed for wall mounting, and that two threaded nuts run on each threaded spindle, on which a jib protruding from the plane of the frame is attached.

Die so gestaltete Hebevorrichtung lässt sich mit dem ebenen, auf den Boden gestellten Rahmen "flach" an der Zimmerwand befestigen, wobei z.B. ein Bett mit den Längsseiten parallel zur Wand von den beiden Auslegern aufgenommen wird. Das Bett ist somit an drei Seiten vollständig frei. Unter dem Bett befinden sich nur die beiden Ausleger, welche zusammen mit dem Bett gehoben werden. Selbstverständlich kann die erfindungsgemässe Hebevorrichtung anstelle eines Bettes auch andere Lasten aufnehmen, im Wohnbereich etwa sperrige Spieleinrichtungen wie Modelleisenbahn-Anlagen usw.; aber auch gewerbliche Anwendungen sind denkbar, etwa die Schaffung von höhenverstellbaren Arbeitsflächen für Montagearbeiten oder dergleichen.The lifting device designed in this way can be attached "flat" to the wall of the room using the flat frame placed on the floor, e.g. a bed with the long sides parallel to the wall is picked up by the two outriggers. The bed is therefore completely free on three sides. Under the bed are only the two outriggers, which are lifted together with the bed. Of course, the lifting device according to the invention can also take up other loads instead of a bed, in the living area, for example, bulky play equipment such as model railroad systems, etc .; but commercial applications are also conceivable, such as the creation of height-adjustable work surfaces for assembly work or the like.

Die dargestellte Hebevorrichtung weist als tragende Konstruktion einen ebenen, starren Rahmen auf, bestehend aus zwei vertikalen Führungssäulen 10, die oben und unten durch je einen Querverbinder 12 verbunden sind (Achsen 13 von Verbindungsschrauben im Querschnitt der Säule 10 in Fig. 4 eingezeichnet). An beiden Querverbindern 12 (und/oder an den Führungssäulen 10) sind Befestigungslaschen oder -winkel 14 angebracht. Mit Hilfe dieser Befestigungsorgane lässt sich die Hebevorrichtung, auf den Fussboden gestellt, leicht an einer Zimmerwand 6 montieren (Fig. 2). Jede der Führungssäulen 10 ist zweckmässigerweise durch ein Vierkant-Hohlprofil mit einem Längsschlitz 11 gebildet; vorzugsweise sind sie als Strangpressprofil aus einer Leichtmetallegierung hergestellt, so dass eine Nachbearbeitung nicht erforderlich ist. Jeder der Führungssäulen 10 ist eine Gewindespindel 20 zugeordnet, die parallel zur Säule im Innern des Profils verläuft und am Rahmen bzw. je im oberen und unteren Querverbinder in einem Lager 21 gelagert ist. An jeder Gewindespindel 20 laufen zwei im Abstand übereinander angeordnete Muttern 22, die an der zugeordneten Führungssäule 10 geführt sind, im vorliegenden Fall an den Innenwänden des Vierkant-Hohlprofils. Zweckmässigerweise sind die Muttern 22 aus einem abriebfesten Kunststoff hergestellt; hinsichtlich Abrieb- und Gleiteigenschaften gegenüber der Führungssäule 10 und einer Gewindespindel 20 mit gerolltem Gewinde ist eine Niederdruck-Polyäthylenmischung (Handelsname "Polydur") besonders geeignet.The lifting device shown has a flat, rigid frame as a supporting structure, consisting of two vertical guide columns 10, which are connected at the top and bottom by a cross connector 12 each (axes 13 of connecting screws in the cross section of the column 10 shown in FIG. 4). Fastening tabs or brackets 14 are attached to both cross connectors 12 (and / or to the guide columns 10). With the help of these fastening elements, the lifting device, placed on the floor, can easily be mounted on a room wall 6 (FIG. 2). Each of the guide columns 10 is expediently formed by a square hollow profile with a longitudinal slot 11; they are preferably produced as an extruded profile from a light metal alloy, so that post-processing is not necessary. Each of the guide columns 10 is assigned a threaded spindle 20 which runs parallel to the column inside the profile and is mounted in a bearing 21 on the frame or in each case in the upper and lower cross connector. Run on each threaded spindle 20 two spaced nuts 22, which are guided on the associated guide column 10, in the present case on the inner walls of the square hollow profile. The nuts 22 are expediently made of an abrasion-resistant plastic; With regard to abrasion and sliding properties compared to the guide column 10 and a threaded spindle 20 with a rolled thread, a low-pressure polyethylene mixture (trade name "Polydur") is particularly suitable.

In der Rahmenebene gesehen, sind die Längsschlitze 11 beider Führungssäulen 10 einander zugekehrt, und die Muttern 22 ragen durch den betreffenden Schlitz hindurch etwas aus dem Profil 10 hervor (Fig. 4). An den beiden übereinanderliegenden Muttern 22 jeder Führungssäule ist ein aus der Ebene des Rahmens herausragender Ausleger für die Lastaufnahme befestigt. Beim vorliegenden Beispiel sind die Ausleger als im wesentlichen ebene Platten 24 gestaltet, mit deren oberem Rand ein Vierkantrohr 25 fest verbunden ist. Bei synchronem Antrieb der beiden Spindeln 20 sind die Ausleger 24 gleichlaufend entlang den zugeordneten Führungssäulen 10 heb- und senkbar; in Fig. 1 sind die beiden Ausleger nahe ihrer unteren Endlage dargestellt. Auf der Oberkante jedes Auslegers sind Halteorgane 26 angebracht, um das Gestell oder den Rahmen 8 eines Bettes 7 aufzunehmen (Fig. 2). Bei Bedarf können die Halteorgane 26 verschiebbar auf den Auslegern befestigt sein, oder die Ausleger können längenverstellbar (ausziehbar) sein, um eine Anpassung an verschieden breite Bettgestelle 8 zu ermöglichen. Am freien Ende jedes Auslegers kann ein Stützfuss 27 angebracht sein, der bei angehobenem Ausleger nach oben geklappt werden kann und dabei unter das Vierkantrohr 25 zu liegen kommt (in Fig. 1 nicht dargestellt).Seen in the frame plane, the longitudinal slots 11 of both guide columns 10 face each other, and the nuts 22 protrude somewhat from the profile 10 through the slot in question (FIG. 4). On the two superimposed nuts 22 of each guide column, an outrigger projecting from the plane of the frame is attached for the load bearing. In the present example, the cantilevers are designed as essentially flat plates 24, with the upper edge of which is connected to a square tube 25. When the two spindles 20 are driven synchronously, the arms 24 can be raised and lowered in the same direction along the associated guide columns 10; in Fig. 1, the two arms are shown near their lower end position. Holding members 26 are mounted on the upper edge of each boom to receive the frame or frame 8 of a bed 7 (Fig. 2). If necessary, the holding members 26 can be slidably attached to the outriggers, or the outriggers can be adjustable in length (extendable) in order to allow adaptation to bed frames 8 of different widths. At the free end of each boom, a support foot 27 can be attached, which can be folded up when the boom is raised and thereby comes to rest under the square tube 25 (not shown in FIG. 1).

Für den synchronen Antrieb der beiden Gewindespindeln 20 ist ein gemeinsamer Antriebsmotor 15 vorgesehen, welcher z. B. am oberen Querverbinder 12 montiert ist. Die Antriebsverbindung vom Ritzel 17 des Motors auf je ein Ritzel 19 am oberen Ende jeder Spindel 20 erfolgt mittels eines Zahnriemens 16, welcher über die genannten Ritzel sowie Führungsrollen 18 und eine Spannrolle 18′ umläuft. Dank diesem Antrieb der Spindeln mit gleichem Drehsinn sind auf beiden Seiten identische Spindeln und Muttern mit Rechtsgewinde verwendbar. Mittels an den Führungssäulen 10 montierten Endschaltern 33, die mit den Muttern 22 zusammenwirken, wird die obere und untere Endlage der Ausleger 24 festgelegt.For the synchronous drive of the two threaded spindles 20, a common drive motor 15 is provided, which, for. B. is mounted on the upper cross connector 12. The drive connection from the pinion 17 of the motor to a pinion 19 at the upper end of each spindle 20 takes place by means of a toothed belt 16, which via the said pinion and guide rollers 18 and one Tension roller 18 'rotates. Thanks to this drive of the spindles with the same direction of rotation, identical spindles and nuts with right-hand thread can be used on both sides. The upper and lower end positions of the brackets 24 are fixed by means of limit switches 33 mounted on the guide columns 10, which interact with the nuts 22.

Mit jedem Ausleger ist ferner eine Abdeckung für den Längsschlitz 11 an der zugeordneten Führungssäule 10 verbunden; es handelt sich um ein zu einer Schleife geformtes Band 31, welches über untere und obere Umlenkrollen 32 geführt ist und beim Heben und Senken der Ausleger mitläuft. Dadurch sind die Spindeln 20 und die innenliegenden Gleitflächen der Führungssäulen 10 gegen Verschmutzung und unbefugten Zugriff geschützt.A cover for the longitudinal slot 11 on the associated guide column 10 is also connected to each boom; it is a band 31 formed into a loop, which is guided over lower and upper deflection rollers 32 and moves with the lifting and lowering of the booms. As a result, the spindles 20 and the inner sliding surfaces of the guide columns 10 are protected against dirt and unauthorized access.

Die beschriebene Hebevorrichtung lässt sich sehr leicht als Einheit transportieren, wobei lediglich die beiden Ausleger noch nicht mit den Muttern 22 verschraubt sind. Der flache Rahmen lässt sich ohne Umstände an einer Zimmerwand befestigen, und anschliessend werden die beiden Ausleger montiert. Nach Erstellung des elektrischen Anschlusses für den Antriebsmotor 15 ist die Vorrichtung gebrauchsfertig. Damit das Heben und Senken der Ausleger nicht unbefugt oder mutwillig (z.B. durch Kinder) erfolgen kann, wird mit Vorteil ein Motorschalter mit Schlüsselsicherung oder Sicherung durch Eingabe einer Codezahl o. dgl. vorgesehen; auch eine Fernbedienung mittels Infrarot-Steuerung o. dgl. ist denkbar.The lifting device described can be transported very easily as a unit, with only the two arms not yet being screwed to the nuts 22. The flat frame can be easily attached to a room wall, and then the two brackets are installed. After establishing the electrical connection for the drive motor 15, the device is ready for use. A motor switch with key lock or security by entering a code number or the like is advantageously provided so that the jibs cannot be raised or lowered unauthorized or willfully (e.g. by children); remote control using infrared control or the like is also conceivable.

Die dargestellte Konstruktion mit zwei an den Säulen 10 geführten Muttern 22 ermöglicht eine sehr wirksame Lastaufnahme und Führung der belasteten Ausleger an den Führungssäulen. Ausserdem kann der Höhenabstand der beiden Muttern auf den Spindeln nach Bedarf gewählt werden, um verschieden hohe Auslegerplatten befestigen können. Mit der Hebevorrichtung können handelsübliche Betten verwendet werden, an deren Rahmen keinerlei Aenderungen oder Montagearbeiten erforderlich sind. Das Bett wird mit der einen Längsseite parallel zur Wand bzw. zum Rahmen von den beiden Auslegern aufgenommen, wobei die drei übrigen Seiten des Bettes völlig frei bleiben. Vor allem ist es von Vorteil, dass bei angehobenem Bett der darunter befindliche Raum, abgesehen von dem flachen, auf der Wand montierten Rahmen, völlig frei zugänglich und nutzbar ist, wie vor allem aus der Fig. 2 hervorgeht. Die Lastaufnahme über selbsthemmend an Spindeln geführte Muttern bietet auch ein hohes Mass an Sicherheit, im Gegensatz etwa zur Lastaufhängung an Seilzügen, Ketten oder dergleichen. Um ein wohnliches Aussehen zu erreichen, kann der gesamte Rahmen hinter einer z.B. als Wohnwand gestalteten Verkleidung verdeckt werden (nicht dargestellt), in welcher zur Durchführung der beiden plattenförmigen Ausleger nur zwei schmale Schlitze vorzusehen sind.The construction shown with two nuts 22 guided on the columns 10 enables a very effective load absorption and guidance of the loaded cantilevers on the guide columns. In addition, the height spacing of the two nuts on the spindles can be selected as required in order to be able to fasten boom plates of different heights. Commercially available beds can be used with the lifting device, on the frame of which no changes or assembly work are required. The bed is with one long side parallel to the wall or frame of the two outriggers, leaving the three remaining sides of the bed completely free. Above all, it is advantageous that when the bed is raised, the space underneath, apart from the flat frame mounted on the wall, is completely freely accessible and usable, as can be seen above all from FIG. 2. The load suspension via self-locking nuts on spindles also offers a high degree of safety, in contrast to the load suspension on cables, chains or the like. In order to achieve a homely appearance, the entire frame can be hidden behind a cladding, for example designed as a wall unit (not shown), in which only two narrow slots are to be provided for carrying out the two plate-shaped brackets.
