Description

Höheneinstellbarer ArbeitstischHeight adjustable work table
Die Erfindung bezieht sich auf einen höheneinstellbaren Arbeitstisch mit zwei Führungsschienen zur Aufnahme einer Arbeitsplatte, die durch einen Antriebsmotor mit Seiltrommeln und Zugseilen in ihrer Arbeitshöhe einstellbar ist.The invention relates to a height-adjustable work table with two guide rails for receiving a worktop, which is adjustable in its working height by a drive motor with cable drums and pull cables.
Es sind Arbeitstische bekannt, zu denen auch Schreibtische oder Werkbänke gehören, die aus einem metallischen Gestell bestehen, welches die sogenannte Arbeitsplatte trägt. Dabei besteht das Gestell zunächst aus einem Untergestell, welches aus mindestens zwei über eine Strebe mit Abstand verbundenen Außenrohren besteht, die eine unterschiedliche Querschnittsform und Querschnittsgröße aufweisen können. In den Außenrohren sind dabei Innenrohre verschiebbar geführt, die entweder ausschließlich über die Arbeitsplatte, bedarfsweise aber auch noch zusätzlich über eine Strebe, miteinander verbunden sind. Jeweils ein Außenrohr und ein Innenrohr bilden dabei ein Stützbein des Arbeitstisches. Um nun die Höhenlage der Arbeitsplatte verändern bzw. vergrößern zu können, ist jeweils im oberen Bereich des Untergestells, vorzugsweise im oberen Bereich des Außenrohres, ein Seil angeschlossen, welches zum unteren Ende des Innenrohres geführt, dort umgelenkt, wieder nach oben geführt und danach im oberen Bereich des Außenrohres in das Untergestell ragt und dort von einer Zugeinheit, die beispielsweise als Seiltrommel ausgebildet sein kann, aufgenommen wird. Dabei sind an die Zugeinheit alle Seile der Stützbeine angeschlossen. Durch entsprechendes Bewegen der Zugeinheit werden nun die Innenrohre aus den Außenrohren allmählich, jedoch in vorgegebenen Grenzen, herausgeschoben, so dass die Arbeitsplatte angehoben wird. Bei einer entgegengesetzten Bewegung der Zugeinheit werden die Zugseile wieder nachgelassen und die Innenrohre bewegen sich aufgrund des Gewichtes, insbesondere der Arbeitsplatte, wieder in die Außenrohre zurück. Die Zugeinheit kann dabei entweder von Hand oder über einen besonderen Antrieb bewegt werden.Work tables are known, which also include desks or workbenches which consist of a metallic frame which carries the so-called worktop. The frame initially consists of a base frame, which consists of at least two outer tubes which are spaced apart via a strut and which can have a different cross-sectional shape and cross-sectional size. Inner tubes are slidably guided in the outer tubes, which are connected to one another either exclusively via the worktop, but if necessary also additionally via a strut. An outer tube and an inner tube each form a support leg of the work table. In order to be able to change or enlarge the height of the worktop, a rope is connected in the upper area of the base frame, preferably in the upper area of the outer tube, which leads to the lower end of the inner tube, deflects there, leads up again and then in protrudes the upper region of the outer tube into the base frame and is picked up there by a pulling unit, which can be designed, for example, as a cable drum. All cables of the support legs are connected to the traction unit. By moving the traction unit accordingly, the inner tubes are now gradually pushed out of the outer tubes, but within predetermined limits, so that the worktop is raised. When the traction unit moves in the opposite direction, the traction cables are released again and the inner tubes move back into the outer tubes due to the weight, in particular the worktop. The pulling unit can be moved either manually or using a special drive.
Derartige Arbeitstische sind in ihrer Herstellung verhältnismäßig aufwendig und teuer. Dies hängt insbesondere damit zusammen, dass die die Stützbeine bildenden Außen- und Innenrohre Sonderprofile sind und über besondere Gleitstücke sehr genau ineinander geführt werden müssen. Aufgrund der Ausgestaltung des Ober- und Untergestells ist der Arbeitstisch vor seiner Auslieferung immer fertig montiert, was hohe Transportkosten mit sich bringt. Ein solcher Arbeitstisch ist darüber hinaus verhältnismäßig schwer, was sich bei dessen Aufstellung nachteilig auswirkt.Such work tables are relatively complex and expensive to manufacture. This is due in particular to the fact that the outer and inner tubes that form the support legs are special profiles and have special sliders have to be brought together very precisely. Due to the design of the upper and lower frame, the work table is always fully assembled before delivery, which entails high transport costs. Such a work table is also relatively heavy, which has a disadvantageous effect when it is set up.
Der Erfindung liegt nun die Aufgabe zugrunde, einen Arbeitstisch mit höheneinstellbarer Arbeitsplatte zu schaffen, der ein verhältnismäßig geringes Gewicht besitzt und äußerst preiswert ist. Darüber hinaus soll der Arbeitstisch so gestaltet sein, dass er leicht in seine Einzelteile zerlegt werden kann, auf kleinem Raum verpackbar ist und von einem Laien problemlos zusammengebaut werden kann.The invention is based on the object of creating a work table with a height-adjustable worktop which has a relatively low weight and is extremely inexpensive. In addition, the work table should be designed so that it can be easily dismantled into its individual parts, can be packed in a small space and can be easily assembled by a layperson.
Zur Lösung dieser Aufgabe wird gemäß der Erfindung ein Arbeitstisch gemäß Anspruch 1 vorgeschlagen.To solve this problem, a work table according to claim 1 is proposed according to the invention.
Ein derartig ausgebildeter Arbeitstisch besitzt bei hoher Stabilität ein verhältnismäßig geringes Gewicht und ist preiswert herzustellen. Für die Führungsschienen können Standardrohre verwendet werden, so dass keine Sonderanfertigung erforderlich ist. Der Arbeitstisch kann - in Einzelteile zerlegt - bei geringem Platzbedarf in einen Karton verpackt, bei geringen Kosten gelagert und damit auch platzsparend transportiert werden. Seine Ausgestaltung ermöglicht es jedem Laien, den erfindungsgemäßen Arbeitstisch ohne besonderes fachliches Können zusammenzubauen. Die Abwärtsbewegung der Arbeitsplatte erfolgt durch deren Gewicht, so dass eine Quetschgefahr des Benutzers erheblich reduziert ist. Die Seilführung ist so ausgebildet, dass das Seil niemals aus seiner Laufbahn herausfällt. Die Arbeitsplatte kann an mehr als zwei Seilen aufgehängt sein, die jeweils angetrieben sind. Alle Antriebsseile werden auf einer Trommel geführt. Der Aufhängungspunkt liegt oberhalb der höchsten Tischposition. Vorzugsweise schaltet sich der Motor bei Entlastung mindestens eines Seiles vorzugsweise automatisch ab und/oder es erfolgt durch elektronische Ansteuerung eine Drehumkehr des Motors, um eine Verkanten der Arbeitsplatte oder eine Verletzung der Benutzer zu vermeiden. Verschiedene Tischhöhen können abgespeichert werden. Die Arbeitsplatte kann neigbar bzw. komplett wegklappbar gestaltet werden. Weitere Merkmale eines Arbeitstisches gemäß der Erfindung sind in den Ansprüchen 2 bis 9 offenbart.A work table designed in this way has a relatively low weight with high stability and is inexpensive to produce. Standard tubes can be used for the guide rails, so that no special production is required. The work table can be disassembled into individual pieces and packed into a carton with a small footprint, stored at low cost and thus transported in a space-saving manner. Its design enables any layperson to assemble the work table according to the invention without any special skill. The worktop is moved downwards by its weight, so that the risk of the user being crushed is considerably reduced. The rope guide is designed so that the rope never falls out of its career. The worktop can be suspended on more than two ropes, each of which is driven. All drive cables are guided on a drum. The suspension point is above the highest table position. When at least one rope is relieved, the motor preferably switches off automatically and / or the motor is reversed by electronic control in order to avoid tilting of the worktop or injury to the user. Different table heights can be saved. The worktop can be tilted or completely folded away. Further features of a work table according to the invention are disclosed in claims 2 to 9.
Die Erfindung wird nachfolgend anhand der Zeichnungen 1 - 14 erläutert. Diese Erläuterungen sind lediglich beispielhaft und schränken den allgemeinen Erfindungsgedanken nicht ein.The invention is explained below with reference to drawings 1-14. These explanations are only examples and do not limit the general idea of the invention.

In Figur 1 ist ein Arbeitstisch 1 gemäß der Erfindung in seitlicher Aufrissdarstellung im Schnitt gezeigt, wobei der Schnitt parallel zur Schmalseite einer Arbeitsplatte 2 verläuft. Der Arbeitstisch 1 besteht aus zwei senkrecht verlaufenden Führungsschienen 3, die im dargestellten Ausführungsbeispiel als Stützbeinen ausgeführt, an der Rückseite der Arbeitsplatte 2 angeordnet und jeweils aus einem Vierkantrohr gefertigt sind und vorteilhaft quadratischen Querschnitt besitzen. Selbstverständlich können auch andere Querschnittsformen gewählt werden. Dabei ist es zweckmäßig, möglichst solche Querschnittsformen zu verwenden, die als Standardrohre auf dem Markt zu erhalten sind und keine Sonderanfertigung erforderlich machen. Das äußere Querschnittsmaß der Stützbeine 3 beträgt etwa 40 bis 50 mm. Im unteren Bereich jedes Stützbeines 1 sind zwei schräg zum Stützbein 3 verlaufende Streben 4,5, beispielsweise durch Schweißung, angeschlossen, die ebenfalls aus einem handelsüblichen Rohr bestehen, die zueinander unter einem Winkel von etwa 90° verlaufen und über die sich das Stützbein 3 auf dem Boden abstützt. Das Stützbein 3 ist somit mit den beiden Streben 4,5 einstickig ausgebildet.In Figure 1, a work table 1 according to the invention in side elevation is shown in section, the section running parallel to the narrow side of a worktop 2. The work table 1 consists of two vertically running guide rails 3, which in the exemplary embodiment shown are designed as support legs, are arranged on the rear of the worktop 2 and are each made from a square tube and advantageously have a square cross section. Of course, other cross-sectional shapes can also be selected. It is advisable to use cross-sectional shapes that are available on the market as standard tubes and that do not require special production do. The outer cross-sectional dimension of the support legs 3 is approximately 40 to 50 mm. In the lower area of each support leg 1, two struts 4, 5, which run obliquely to the support leg 3, are connected, for example by welding, which also consist of a commercially available tube, which run at an angle of approximately 90 ° to one another and over which the support leg 3 extends supports the ground. The support leg 3 is thus formed in one piece with the two struts 4, 5.
Beide derartig mit den Streben 4,5 einstückig ausgebildeten Stützbeine 3 sind durch ein L-förmigen Querschnitt aufweisendes Blech 6 fest, jedoch lösbar miteinander verbunden. Diese Verbindung erfolgt, wie in der Zeichnung angedeutet, durch Schrauben 7. Diese Schrauben 7 werden in sogenannte Knotenbleche 8 eingesteckt, die im Blech 6 eingesetzt sind. Es ist jedoch auch möglich, diese Teile formschlüssig, beispielsweise durch „Einhaken" miteinander zu verbinden. Diese lösbare Verbindung gibt die Möglichkeit, den Arbeitstisch 1 zu zerlegen und dann die Stützbeine 3 mit den Streben 4,5 auf kleinstem Raum zu verpacken. Bei der eigentlichen Montage werden also zunächst die beiden Stützbeine 3 aufgestellt und über das Blech 6 miteinander verbunden. Dadurch entsteht eine stabile, tragende Einheit. Das einen L-förmigen Querschnitt aufweisende Blech 6 kann als sogenannter Kabelkanal genutzt werden.Both support legs 3 formed in one piece with the struts 4, 5 are fixed, but releasably connected by a sheet 6 having an L-shaped cross section. This connection is made, as indicated in the drawing, by screws 7. These screws 7 are inserted into so-called gusset plates 8, which are inserted in the plate 6. However, it is also possible to connect these parts to one another in a form-fitting manner, for example by “hooking in.” This detachable connection enables the work table 1 to be disassembled and then the support legs 3 with the struts 4, 5 to be packed in the smallest space Actual assembly, the two support legs 3 are first set up and connected to one another via the sheet 6. This creates a stable, load-bearing unit 6. The sheet 6, which has an L-shaped cross section, can be used as a so-called cable duct.
Der Arbeitstisch 1 weist ferner zwei Traversen 9 auf, die U-förmig aus Blech mit einer Wandstärke von 2,00 bis 4,00 mm gekantet und nach unten offen sind. An ihren rückwärtigen Enden ist der Steg dieser Traversen 9 ausgeklinkt, so dass jeweils eine Traverse 9 von oben über ein Stützbein 3 aufgeschoben werden kann. Beide Traversen 9 sind durch ein U-Profilblech 10 mit einer Wandstärke von 1 ,50 bis 3,00 fest miteinander verbunden. Diese Verbindung kann dabei bereits werksseitig hergestellt werden und lösbar oder unlösbar ausgelegt sein. Für das Verpak- ken des Arbeitstisches 1 muss diese Verbindung jedoch nicht getrennt werden, da diese Einheit in ihrer Grundfläche nicht größer ist als die Gesamtfläche der Stützbeine 3. Um nun die beiden Traversen 9 an den Stützbeinen 3 bewegen und damit heben und senken zu können, besitzt jede Traverse 9 eine obere, hintere und eine untere, vordere Laufrolle 11 ,12, die beispielsweise durch ein Kugellager gebildet und drehbar zwischen den Schenkeln einer Traverse 9 gehalten sind und an einem Stützbein 3 anliegen. Zusätzlich ist an jedem seitlichen Schenkel der Traversen 9 ein ebenfalls am senkrechten Stützbein 3 anliegendes Gleitstück vorgesehen, so dass eine gute und sichere Führung der Traversen 9 an den Stützbeinen 3 sichergestellt ist.The work table 1 also has two crossbeams 9, which are bent in a U-shape from sheet metal with a wall thickness of 2.00 to 4.00 mm and are open at the bottom. The web of these cross members 9 is notched at their rear ends, so that one cross member 9 can be slid on from above via a support leg 3. Both trusses 9 are firmly connected to one another by a U-shaped sheet 10 with a wall thickness of 1.50 to 3.00. This connection can already be made at the factory and can be designed to be detachable or non-detachable. For the packaging of the work table 1, however, this connection does not have to be separated, since the base area of this unit is not larger than the total area of the support legs 3. In order to be able to move the two crossbeams 9 on the support legs 3 and thus be able to raise and lower them , Each crossmember 9 has an upper, rear and a lower, front rollers 11, 12, which are formed, for example, by a ball bearing and are rotatably held between the legs of a crossmember 9 and on one Support leg 3. In addition, on each side leg of the crossbeams 9 there is also a sliding piece which bears against the vertical support leg 3, so that good and secure guidance of the crossbeams 9 on the support legs 3 is ensured.
Das U-Profilblech 10 ist nach oben offen zwischen die beiden Traversen 9 eingesetzt und nimmt einen an sich bekannten Antriebsmotor mit einer Welle und mindestens einer Seiltrommel mit zwei über Umlenkrollen geführten Zugseilen 13 auf. Auch die Anordnung von zwei Seiltrommeln ist möglich. Diese Teile sind an sich bekannt und wurden deshalb nicht in der Zeichnung eingezeichnet.The U-shaped plate 10 is inserted open between the two traverses 9 and accommodates a drive motor known per se with a shaft and at least one cable drum with two pull cables 13 guided over deflection rollers. The arrangement of two rope drums is also possible. These parts are known per se and were therefore not shown in the drawing.
Sobald die vorbeschriebene Montage durchgeführt ist, werden die freien Enden der Zugseile jeweils an einem oberen Ende der Stützbeine 3, welche dazu besonders ausgebildet sind, eingehängt. Die Zugseile 13 sind in Umlenkrollen so geführt, dass diese die Laufnut der Umlenkrollen, auch bei nachlassender Seilspannung, niemals verlassen können. Dies gilt auch dann, wenn der Arbeitstisch 1 für einen Transport zerlegt und dazu die Zugseile 13 ausgehängt werden. Nach dem Anschalten des Antriebsmotors werden nun beide Traversen 9 gleichzeitig und gleichmäßig stufenlos durch den Motor nach oben gezogen oder nach unten durch ihr Eigengewicht und das Gewicht der Arbeitsplatte 2 abgelassen. Damit kann die Arbeitsplatte 2, die auf den beiden Traversen 9 beispielsweise mittels Schrauben befestigt ist, angehoben oder abgesenkt werden. Die Abwärtsbewegung der Traversen 9 und damit das Absenken der Arbeitsplatte 2 erfolgt ausschließlich durch das Eigengewicht von Arbeitsplatte 2, Traversen 9 und U-Profilblech 10 mit den darin befindlichen Antriebsteilen. Der Antrieb übt dazu keinerlei Kräfte auf die Traversen 9 aus. Bei nachlassender Spannung der Zugseile wird der Antriebsmotor sofort über einen besonderen Schalter abgeschaltet. Der Verstellhub der Arbeitsplatte 2 beträgt etwa 600 mm und ermöglicht eine Arbeitshöhe der Arbeitsplatte 2 zwischen 650 und 1250 mm.As soon as the assembly described above has been carried out, the free ends of the traction cables are each attached to an upper end of the support legs 3, which are specially designed for this purpose. The traction cables 13 are guided in deflection pulleys in such a way that they can never leave the running groove of the deflection pulleys, even when the cable tension decreases. This also applies when the work table 1 is disassembled for transport and the traction cables 13 are unhooked for this purpose. After the drive motor has been switched on, both traverses 9 are pulled upwards simultaneously and smoothly by the motor, or let down by their own weight and the weight of the worktop 2. The worktop 2, which is fastened on the two cross members 9, for example by means of screws, can thus be raised or lowered. The downward movement of the crossbeams 9 and thus the lowering of the worktop 2 takes place exclusively through the dead weight of worktop 2, crossbeams 9 and U-shaped sheet metal 10 with the drive parts located therein. The drive does not exert any forces on the crossbeams 9. If the tension of the traction cables diminishes, the drive motor is switched off immediately via a special switch. The adjustment stroke of the worktop 2 is approximately 600 mm and enables a working height of the worktop 2 between 650 and 1250 mm.
In Abänderung des erläuterten Ausführungsbeispieles ist es möglich, die senkrechten Rohre der Stützbeine 3 nicht rückseitig, sondern seitlich an der Arbeitsplatte 2 anzuordnen. Die Traversen 9 sollten dann jedoch möglichst quer vor den Stützbeinen 3 verlaufen, damit eine ausreichende Standsicherheit des Arbeitsti- sches 1 gewährleistet ist. Gegebenenfalls sind dann auch die Stützbeine 9 mit den Streben 4,5 anders auszubilden.In a modification of the exemplary embodiment explained, it is possible not to arrange the vertical tubes of the support legs 3 on the rear, but laterally on the worktop 2. The crossbeams 9 should then run as far as possible in front of the support legs 3 so that sufficient stability of the work sches 1 is guaranteed. If necessary, the support legs 9 with the struts 4, 5 are then to be designed differently.
Figur 2 zeigt eine mögliche Ausgestaltungsform des Antriebes der Arbeitsplatte 2, die wie oben beschrieben an den Führungsschienen 3 gelagert ist. Das Zugseil 13 ist mit seinem einen Ende am oberen Ende der Führungsschiene 3 gelagert. Das Zugseil wird auf der Seiltrommel 14 mittels des Motors 15 auf und abgerollt.Figure 2 shows a possible embodiment of the drive of the worktop 2, which is mounted on the guide rails 3 as described above. The pull rope 13 is supported at one end at the upper end of the guide rail 3. The traction cable is rolled up and down on the cable drum 14 by means of the motor 15.
Figur 3a zeigt eine bevorzugte Ausführungsform der Aufhängung 16 des Seiles 13 an dem oberen Ende der Führungsschiene. Die Aufhängung 16 besteht im wesentlichen aus einem Stopfen 17, der vorzugsweise zumindest teilweise formschlüssig von der Führungsschiene 3 aufgenommen wird und sich auf deren Wandung abstützt. In dem Stopfen 17 ist das Seil so angeordnet, dass es auf Zug (durch den Pfeil dargestellt) belastbar ist. Zur Montage des erfindungsgemäßen Arbeitstisches wird der Stopfen 17 auf die Führungsschiene 3 aufgesteckt und kann bei der Demontage wieder angenommen werden.Figure 3a shows a preferred embodiment of the suspension 16 of the rope 13 at the upper end of the guide rail. The suspension 16 essentially consists of a stopper 17, which is preferably at least partially positively received by the guide rail 3 and is supported on the wall thereof. The rope is arranged in the plug 17 in such a way that it can be subjected to tension (represented by the arrow). To assemble the work table according to the invention, the plug 17 is pushed onto the guide rail 3 and can be accepted again during the disassembly.
Figur 3b zeigt eine bevorzugte Ausführungsform der Lagerung der Traverse 9 an der Führungsschiene 3 in zwei Ansichten. In dem vorliegenden Fall greifen die Rollen 11, 12 an dem inneren Querschnitt des Profils 3 an, wobei die Rollen 12 vorne und die Rollen 11 hinten angeordnet sind. Der Fachmann erkennt, dass das Profil in diesem Fall einen Schlitz 20 aufweisen muss, in dem sich die Traverse auf- und ab bewegt. In der Traverse ist zusätzlich eine Rolle 18 angebracht, um die das Seil 13 von der Seiltrommel (nicht dargestellt) zu der Halterung 16 (nicht dargestellt) umgelenkt wird.Figure 3b shows a preferred embodiment of the mounting of the crossmember 9 on the guide rail 3 in two views. In the present case, the rollers 11, 12 engage the inner cross section of the profile 3, the rollers 12 being arranged at the front and the rollers 11 at the rear. The person skilled in the art recognizes that in this case the profile must have a slot 20 in which the crossmember moves up and down. In addition, a roller 18 is attached in the traverse, around which the cable 13 is deflected by the cable drum (not shown) to the holder 16 (not shown).
Figur 4 zeigt die Lagerung des Motors 15 und der Seiltrommel 14 an der Arbeitsplatte 2 dargestellt, wobei die Arbeitsplatte 2 nicht dargestellt ist. Das Zugseil 13 wird von der Seiltrommel 14 über eine Rolle 19 zu der Rolle 18 geleitet. Es ist zu erkennen, dass zwei Zugseile 13 auf einer Rolle 14 laufen, so dass die Auf- und Abwärtsbewegung an den beiden Führungsschienen 3 (nur eine dargestellt) nicht synchronisiert werden muss. Der Fachmann erkennt, dass auch drei oder mehr Zugseile auf einer Seiltrommel geführt werden können. Figuren 5 - 14 zeigt mögliche Ausführungsformen des erfindungsgemäßen Arbeitstisches. Bei der Ausführungsform gemäß Figur 8 weist der Arbeitstisch drei Führungsschienen 3 auf, so dass die Arbeitsplatte an drei Stellen angehoben bzw. abgesenkt wird. Der Arbeitstisch gemäß Figur 10 weist ein Scharnier 21 auf, so dass die Arbeitsplatte 2 abklappbar ist und Scharniere 25, mit denen die Beinausleger 26 einklappbar sind. Bei der Ausführungsform gemäß Figur 11 ist der Arbeitstisch in einer Kiste angeordnet, um beispielsweise einen Fernseher anheben oder absenken zu können. In Figur 12 sind die Führungsschienen 3 an einer Wand montiert und in Figur 13 sind die Führungsschienen 3 als Stützbeine ausgeführt und durch die Traverse 22 kraftschlüssig miteinander verbunden. Figur 14 zeigt eine weitere Ausführungsform der Traverse 22, die in dem vorliegenden Fall formschlüssig mit den Stützbeinen 3 zusammenwirkt , die durch die Seile 23 miteinander verspannt sind.FIG. 4 shows the mounting of the motor 15 and the cable drum 14 on the worktop 2, the worktop 2 not being shown. The pull rope 13 is guided by the rope drum 14 via a roller 19 to the roller 18. It can be seen that two traction cables 13 run on a roller 14, so that the up and down movement on the two guide rails 3 (only one shown) does not have to be synchronized. The person skilled in the art recognizes that three or more traction cables can also be guided on a cable drum. FIGS. 5-14 show possible embodiments of the work table according to the invention. In the embodiment according to FIG. 8, the work table has three guide rails 3, so that the worktop is raised or lowered at three points. The work table according to FIG. 10 has a hinge 21 so that the worktop 2 can be folded down and hinges 25 with which the leg supports 26 can be folded in. In the embodiment according to FIG. 11, the work table is arranged in a box, for example in order to be able to raise or lower a television. In Figure 12, the guide rails 3 are mounted on a wall and in Figure 13, the guide rails 3 are designed as support legs and non-positively connected by the cross member 22. FIG. 14 shows a further embodiment of the crossmember 22, which in the present case interacts positively with the support legs 3, which are braced together by the ropes 23.
In Figur 15 ist eine weitere Ausführungsform des Arbeitstisches 1 gemäß der Erfindung gezeigt. Der Arbeitstisch 1 besteht aus zwei senkrecht verlaufenden Führungsschienen 3, die im dargestellten Ausführungsbeispiel als Stützbeinen ausgeführt, an der Rückseite der Arbeitsplatte 2 angeordnet und jeweils aus einem Vierkantrohr gefertigt sind und vorteilhaft quadratischen Querschnitt besitzen. Selbstverständlich können auch andere Querschnittsformen gewählt werden. Dabei ist es zweckmäßig, möglichst solche Querschnittsformen zu verwenden, die als Standardrohre auf dem Markt zu erhalten sind und keine Sonderanfertigung erforderlich machen. Das äußere Querschnittsmaß der Stützbeine 3 beträgt etwa 40 bis 50 mm. Im unteren Bereich jedes Stützbeines 1 sind zwei schräg zum Stützbein 3 verlaufende Streben 4,5, beispielsweise durch Schweißung, angeschlossen, die ebenfalls aus einem handelsüblichen Rohr bestehen, die zueinander unter einem Winkel von etwa 90° verlaufen und über die sich das Stützbein 3 auf dem Boden abstützt. Das Stützbein 3 ist somit mit den beiden Streben 4,5 einstückig ausgebildet.FIG. 15 shows a further embodiment of the work table 1 according to the invention. The work table 1 consists of two vertically running guide rails 3, which in the exemplary embodiment shown are designed as support legs, are arranged on the rear of the worktop 2 and are each made from a square tube and advantageously have a square cross section. Of course, other cross-sectional shapes can also be selected. It is advisable to use cross-sectional shapes that are available on the market as standard tubes and that do not require special production. The outer cross-sectional dimension of the support legs 3 is approximately 40 to 50 mm. In the lower region of each support leg 1, two struts 4, 5, which run obliquely to the support leg 3, are connected, for example by welding, which also consist of a commercially available tube, which run at an angle of approximately 90 ° to one another and over which the support leg 3 extends supports the ground. The support leg 3 is thus formed in one piece with the two struts 4, 5.
Beide derartig mit den Streben 4,5 einstückig ausgebildeten Stützbeine 3 sind durch ein Blech (nicht dargestellt) fest, jedoch lösbar miteinander verbunden. Diese lösbare Verbindung gibt die Möglichkeit, den Arbeitstisch 1 zu zerlegen und dann die Stützbeine 3 mit den Streben 4,5 auf kleinstem Raum zu verpacken. Bei der eigentlichen Montage werden also zunächst die beiden Stützbeine 3 aufgestellt und über das Blech miteinander verbunden. Dadurch entsteht eine stabile, tragende Einheit.Both support legs 3 formed in one piece with the struts 4, 5 are fixed to one another by a sheet metal (not shown), but are detachably connected to one another. This detachable connection gives the opportunity to disassemble the work table 1 and then pack the support legs 3 with the struts 4, 5 in the smallest space. In the Actual assembly, the two support legs 3 are first set up and connected to one another via the sheet metal. This creates a stable, load-bearing unit.
Der Arbeitstisch 1 weist ferner zwei Traversen 9 auf, die U-förmig aus Blech mit einer Wandstärke von 2,00 bis 4,00 mm gekantet und nach unten offen sind. Um nun die beiden Traversen 9 an den Stützbeinen 3 bewegen und damit heben und senken zu können, besitzt jede Traverse 9 eine obere, hintere und eine untere, vordere Laufrolle 11 ,12, die beispielsweise durch ein Kugellager gebildet und drehbar zwischen den Schenkeln einer Traverse 9 gehalten sind und an einem Stützbein 3 anliegen. Der Fachmann erkennt, dass das Profil in diesem Fall einen Schlitz aufweisen muss, in dem sich die Traverse auf- und ab bewegt.The work table 1 also has two crossbeams 9, which are bent in a U-shape from sheet metal with a wall thickness of 2.00 to 4.00 mm and are open at the bottom. In order to be able to move the two crossbeams 9 on the support legs 3 and thus raise and lower them, each crossbeam 9 has an upper, rear and a lower, front roller 11, 12, which is formed, for example, by a ball bearing and rotatable between the legs of a crossbeam 9 are held and rest on a support leg 3. The person skilled in the art recognizes that in this case the profile must have a slot in which the crossmember moves up and down.
Sobald die vorbeschriebene Montage durchgeführt ist, wird das Zugseil 13 von dem Motor 15 über eine Umlenkrolle 30 geführt und im Bereich der Rolle 12 an der Traverse 9 befestigt. Nach dem Anschalten des Antriebsmotors werden nun beide Traversen 9 gleichzeitig und gleichmäßig stufenlos durch den Motor nach oben gezogen oder nach unten durch ihr Eigengewicht und das Gewicht der Arbeitsplatte 2 abgelassen. Damit kann die Arbeitsplatte 2, die auf den beiden Traversen 9 beispielsweise mittels Schrauben befestigt ist, angehoben oder abgesenkt werden. Die Abwärtsbewegung der Traversen 9 und damit das Absenken der Arbeitsplatte 2 erfolgt ausschließlich durch das Eigengewicht von Arbeitsplatte 2 und Traversen 9. Der Antrieb übt dazu keinerlei Kräfte auf die Traversen 9 aus. Bei nachlassender Spannung der Zugseile wird der Antriebsmotor sofort über einen besonderen Schalter abgeschaltet. Der Verstellhub der Arbeitsplatte 2 beträgt etwa 600 mm und ermöglicht eine Arbeitshöhe der Arbeitsplatte 2 zwischen 650 und 1250 mm. As soon as the assembly described above has been carried out, the pull cable 13 is guided by the motor 15 over a deflection roller 30 and fastened to the cross member 9 in the region of the roller 12. After the drive motor has been switched on, both traverses 9 are pulled upwards simultaneously and smoothly by the motor, or let down by their own weight and the weight of the worktop 2. The worktop 2, which is fastened on the two cross members 9, for example by means of screws, can thus be raised or lowered. The downward movement of the crossbeams 9 and thus the lowering of the worktop 2 takes place exclusively through the weight of the worktop 2 and crossbeams 9. The drive does not exert any forces on the crossbeams 9 for this purpose. If the tension of the traction cables diminishes, the drive motor is switched off immediately via a special switch. The adjustment stroke of the worktop 2 is approximately 600 mm and enables a working height of the worktop 2 between 650 and 1250 mm.
