Description

Die Erfindung betrifft eine Hebeeinrichtung mit den Merkmalen des Oberbegriffes von Anspruch 1. Bei einer derartigen bekannten Einrichtung ( FR-OS 2 356 389 ) mit einer aus einer Pumpe und einem vertikal angeordneten hydraulischen Zylinder bestehenden Antriebsvorrichtung trägt die Kolbenstange eine Seil-Umlenkrolle. Das mit dem einen Ende am Grundrahmen und mit dem anderen Ende amTragboden befestigte Seil als Verbindungsmittel zwischen dem Tragboden und der Antriebsvorrichtung bewirkt die Verdoppelung des Kolbenhubes, verändert aber dabei seine belastete Länge nicht.The invention relates to a lifting device with the features of the preamble of claim 1. In such a known device (FR-OS 2 356 389) with a drive device consisting of a pump and a vertically arranged hydraulic cylinder, the piston rod carries a cable deflection roller. The amTragboden with one end on the base frame and with the other end attached cable as the connecting means between the T ragboden and the drive device causes a doubling of the piston stroke, but not altered thereby its load bearing length.

Die bekannte Hebeeinrichtung hat den Nachteil, aufwendig zu sein. Eine Fernsehtruhe in größerem Umfang zu einem allgemeinen Gebrauchsmöbel zu machen, setzt nämlich vor allem eine billig herstellbare Hebeeinrichtung voraus. Weiterer Nachteil des hydraulischen Antriebes in einer Wohnung ist die Gefahr des Undichtwerdens und des Auslaufens hydraulischer Flüssigkeit etwa auf einen Teppich.The known lifting device has the N downside of being expensive. To make a television chest to a large extent a general piece of furniture requires, above all, an inexpensive lifting device. Another disadvantage of the hydraulic drive in an apartment is the risk of leakage and leakage of hydraulic fluid, for example on a carpet.

Die Erfindung bezweckt, eine Hebeeinrichtung der bezeichneten Art zu schaffen, die billig herstellbar und auch sonst unbedenklich ist. Zur Lösung dieser Aufgabe sieht die Erfindung die Merkmale des kennzeichnenden Teils des Anspruches 1 vor und in bevorzugter Ausführungsform die Merkmale von Anspruch 2.The invention aims to provide a lifting device of the type described, which is inexpensive to manufacture and also otherwise harmless. To achieve this object, the invention provides the features of the characterizing part of claim 1 and, in a preferred embodiment, the features of claim 2.

Ein sich bei der Aufwärtsbewegung eines Tragbodens zwischen den Kraftangriffspunkten verkürzendes Verbindungsmittel, nämlich eine Seilanordnung, ist bei einem höhenverstellbaren Tisch an sich bekannt ( DE-PS 876 321 ).Log during the upward movement of the tray between the K raftangriffspunkten verkürzendes connecting means, namely, a cable arrangement, wherein a height-adjustable table is known per se (DE-PS 876 321).

Die zweckmäßige Ausführungsform nach Anspruch 3 sieht mit dem vergleichsweise schwach belasteten Seil aus Kunststofffasern ein besonders billiges Verbindungsmittel vor. Ferner läßt sich der geringen Kraft wegen ein für Fahrzeug-Scheibenwischer üblicher, also wegen Großstückzahlfertigung besonders billiger kleiner Motor mit Kunststoff-Schneckenrad verwenden. Dabei wird der Verbilligungseffekt nicht etwa durch den Aufwand einer sichernden Bremsvorrichtung wieder aufgehoben, sondern es ist der Einbau einer sichernden Bremsvorrichtung grundsätzlich bei allen denkbaren Hebeeinrichtungen von Fernsehtruhen geboten, bei der Erfindung nur in erhöhtem Maße.The expedient embodiment according to claim 3 provides a particularly inexpensive connecting means with the comparatively weakly loaded rope made of plastic fibers. Furthermore, because of the low force, a small motor with a plastic worm wheel that is customary for vehicle windshield wipers, that is to say because of large-scale production, is particularly cheap. Here, the V erbilligungseffekt rather than offset by the cost of a conservatory braking device, but it is fundamentally necessary to install a device-locking braking in all conceivable lifting equipment of TV tables Resting in the invention only to an increased extent.

Das Merkmal von Anspruch 4 ist an sich bekannt ( DE-GM 1 983 177 ). Der besondere Vorteil des Scherengestänges ist bei der Erfindung die Ausbildung der Hebeeinrichtung als fabrikmäßig fertig herstellbare und von einer Möbelfirma oder im Idealfall durch den Benutzer selbst nur nach hineinzustellende Kompakteinheit, wie weiter unten beschrieben ist. In dem Sinne beinhaltet der Anspruch 5 einen Kompromiß und der Anspruch 6 die optimale Ausführungsform.The feature of claim 4 is known per se (DE-GM 1 983 177). The particular advantage of the scissors linkage in the invention is the design of the lifting device as a factory-made compact unit that can only be inserted by a furniture company or ideally by the user himself, as described below. In this sense, claim 5 includes a compromise and claim 6 the optimal embodiment.

Die optimale Ausführungsform mit einem im wesentlichen horizontalen Flaschenzug besitzt mit der Entlastungsvorrichtung ein Mittel, das den Flaschenzug von der übergroßen Sehnenkraft des völlig eingefahrenen Scherengestänges befreit. Zwar ist es möglich, die übergroße Sehnenkraft mit einem Vielrollen-Flaschenzug allein zu beherrschen, aber das geht zu Lasten der Hubgeschwindigkeit des Tragbodens im mittleren und oberen Höhenbereich. Überdies würde die gesamte Stabkonstruktion für die Aufnahme der übergroßen Sehnenkraft ein zu großes Gewicht erhalten, was dem Kostenprinzip zuwiderläuft.The optimal embodiment with an essentially horizontal pulley has, with the relief device, a means which frees the pulley from the oversized tendon force of the fully retracted scissor linkage. It is possible to master the oversized tendon force with a multi-pulley pulley block alone, but this is at the expense of the lifting speed of the supporting floor in the middle and upper height range. In addition, the entire rod structure would be too heavy for the absorption of the oversized tendon force, which runs counter to the cost principle.

Die Alternativen gemäß den Ansprüchen 7 und 8 mit Anspruch 9 als zweckmäßige Ausführungsform von Anspruch 8 sehen als Entlastungsvorrichtung einmal eine Feder und zum anderen einen Winkelhebel vor. Dabei hat die etwas aufwendigere Winkelhebelausführung den Vorteil der vollendeten Optimalausführung der Kompakteinheit, bei der für den Einbau in das Möbelstück überhaupt kein besonderes Einzelteil nachträglich hinzuzufügen ist.The alternatives according to claims 7 and 8 with claim 9 as a useful embodiment of claim 8 provide a spring and on the other hand an angle lever as a relief device. The somewhat more complex angle lever design has the advantage of the perfect design of the compact unit, in which there is no need to add any special parts at all for installation in the piece of furniture.

Auf einer Fernsehtruhe 1 mit nach hinten heruntergeschwenktem Deckel 2 steht auf einem um die Achse 3 drehbaren Teller 4 ein Fernsehgerät 5. Ein kastenartig ausgebildeter Tragboden 6 nimmt mit seinem oberen Brett 6 a den Drehteller 4 und mit seinem unteren Brett 6 b einen Videorecorder 7 auf, der über eine an der Vorderwand der Truhe angelenkte Klappe 8 in die Gebrauchsstellung herausziehbar ist.On an F ernsehtruhe 1 with rearwardly heruntergeschwenktem cover 2 is mounted on a rotatable about the axis 3. Plate 4 is a television set 5. A box-like design support base 6 increases its upper board 6 a the turntable 4 and with its lower board 6 b a VCR 7 which can be pulled out into the use position via a flap 8 hinged to the front wall of the chest.

In die Truhe ist eine Hebeeinrichtung hineingebaut, deren Einzelteile an entsprechenden Innenteilen der Truhe befestigt sind. In der Summe der Teile besteht die Hebeeinrichtung aus einem unterhalb des Tragbodens 6 angeordneten selbstsperrenden "etriebemotor 9, nämlich einem Schneckengetriebemotor. Die durchgehende Schneckenradwelle ist mit einem Paar Windeltrommer10 versehen, so daß insgesamt vier Seilwicklungen vorhanden sind.A lifting device is built into the chest, the individual parts of which are fastened to corresponding inner parts of the chest. In the sum of the parts, the lifting device consists of a self-locking "drive motor 9", namely a worm gear motor, which is arranged underneath the support base 6. The continuous worm gear shaft is provided with a pair of diaper drums 10, so that a total of four cable windings are present.

Vier Seile 11 als Verbindungsmittel zwischen dem Trommelpaar 10 als dem einen Kraftangriffspunkt und dem unteren Brett 6 b das Tragbodens als dem anderen Kraftangriffspunkt verkürzen sich bei der Aufwärtsbewegung des Tragbodens durch Aufwickeln. Die Seile sind über fest angeordnete Umlenkrollen 12 so verlegt, daß der an seinen vier Ecken abgetragene Tragboden in allen Höhenlagen die Horizontale beibehält, also im Gleichlauf geführt ist. Zur Gleichlaufführung gehören ferner die Leisten 13, die das seitliche Spiel des Tragbodens eng begrenzen und bei einem Riß eines der vier Seile den sich dadurch verkantenden Tragboden verklemmen, also festbremsen.Four ropes 11 as connecting means between the pair of drums 10 as the force application point and the lower board 6 b the supporting base than the other force application point of the T are reduced with the upward movement ragbodens by winding. The ropes are laid over fixed deflection pulleys 12 so that the supporting floor removed at its four corners maintains the horizontal at all altitudes, that is to say is guided in synchronism. The synchronism also includes the strips 13, which narrowly limit the lateral play of the support floor and, if one of the four ropes breaks, jam the support floor which is thereby tilted, that is, brake it.

Die Seilkraft und die Seilgeschwindigkeit sind auch dann über den ganzen Hubweg mit der Last und der Hubgeschwindigkeit des Tragbodens proportional, wenn die Seile über Flaschenzugrollen verlegt sind. Das ist eine positive Eigenschaft der Einrichtung. Positiv ist auch der minimale Materialbedarf. Negativ ist die Notwendigkeit, daß der Möbeln tischler an jeder Truhe die Hebeeinrichtung Teil für Teil montieren muß und für die Gesamtfunktion verantwortlich ist. Das ist lohnintensiv, so daß die im Vergleich zum Stand der Technik billigere Herstellung in der Summe nur bedingt vorhanden ist. Demgegenüber zeigt die in Seilkraft und Seilgeschwindigkeit vergleichbare Ausführungsform nach Figur 4 bis 6 eine außerhalb der Möbelfabrik in einem Gerätebaubetrieb herstellbare Kompakteinheit, die zwar einen etwas höheren Materielaufwand aufweist, dafür aber deutlich weniger lohnintensiv ist.The rope force and the rope speed are then also with the load and the lifting speed over the entire stroke of the supporting floor is proportional if the ropes are laid over pulley blocks. This is a positive feature of the facility. The minimal material requirement is also positive. Negative is the need that the rest furniture carpenter at each T, the lifter must assemble part by part and esamtfunktion for G is responsible. This is wage-intensive, so that the sum of the cheaper production compared to the prior art is limited. In contrast, the comparable in cable force and line speed to embodiment of Figure 4 Figure 6 shows a manufacturable outside the furniture factory in a device Construction compact unit which, while having a slightly higher M aterielaufwand, but is much less labor-intensive.

Gemäß Figur 4 bis 6 bilden ein Grundrahmen 14, ein Tragboden 15 und zwei sich kreuzende Stabpaare 16 und 17 ein Scherengestänge 18. Der Tragboden entspricht dem "ragboden 6, ist aber in dem Beispiel nicht kastenartig ausgebildet. In der Gesamttiefe A einer Fernsehtruhe nimmt das Scherengestänge 18 nur den vorderen Teil ein entsprechend der Tiefe des quaderförmigen Gehäusevorderteils eines Fernsehgerätes. Der freie hintere Teil der Tiefe A läßt daher Platz für einen Schaltkasten 19, der auch den Getriebemotor 20 aufnimmt.According to figure 4 to 6 forming a base frame 14, a tray 15, and two crossing rod pairs 16 and 17 is a projecting arm 18. The support base corresponds ragboden 6 the ", but is not formed like a box in the example. In the G esamttiefe A of a TV tables takes the scissors linkage 18, only the front part of a corresponding to the depth of the block-shaped housing front part of a television device. the free rear part of the depth a may therefore accommodate a switch 19, which also etriebemotor the G receives 20th

Auf der Schneckenradwelle des Getriebemotors 20 sitzt eine sich über die Tiefe des Scherengestänges erstreckende Windentrommel 21 mit zwei Seilwicklungen. Ein mittig angeordneter vertikaler Holm 22 trägt am oberen Ende den Festrollensatz 23 von zwei vertikalen, symmetrisch zum Holm angeordneten Flaschenzügen 24 mit je einer Losrolle 25. Wegen der Zwangsführungseigenschaft des Scherengestänges genügt in der aus der FR-OS 2 356 389 bekannten Weise der einseitige Kraftangriff am Tragboden.On the worm shaft of the G etriebemotors 20 extending over the depth of the scissors linkage winch drum 21 sits with two cable windings. A centrally arranged vertical spar 22 carries at the upper end the fixed roller set 23 of two vertical pulleys 24 arranged symmetrically to the spar, each with a loose roller 25 on the supporting floor.

Gemäß Figur 5 und 6 ist der Holm 22 mit zwei Schrauben 26 leicht lösbar an einem Distanzstück 27 des Grundrahmens 14 befestigt. Die Befestigung kann auch eine köcherartige Einsteckverbindung sein. Im Transportzustand der Einrichtung ist der Holm 22 nämlich ausgebaut und liegt gemäß Figur 6 auf dem Tragboden 15 des eingefahrenen Scherengestänges auf. Das Maß B bezeichnet die Höhe des Packstückes. Vor dem Einbau der Hebeeinrichtung in die Truhe befestigt der Möbel« tischler den Holm 22 am Grundrahmen, ordnet das versandmäßig fertig verlegte Seilsystem und erhält damit die strichpunktiert angedeutete Gebrauchsform der Kompakteinheit.According to FIGS. 5 and 6, the spar 22 is easily detachable with two screws 26 on a spacer 27 of the base frame 14 attached. The attachment can also be a quiver-like plug-in connection. In the transport state of the device, the spar 22 is namely removed and, according to FIG. 6, rests on the support base 15 of the retracted scissor linkage. The M aß B denotes the height of the package. Before the lifting device is installed in the chest, the cabinet maker attaches the spar 22 to the base frame, arranges the rope system, which has been laid out ready for shipment, and thus receives the use form of the compact unit indicated by dash-dotted lines.

In Figur 4 and 6 ist ein Stoßdämpfer 28 eingezeichnet, der als Bremsvorrichtung bei Seilbruch oder bei irgendeiner anders begründeten Überschreitung der vorbestimmten Abwärtsgeschwindigkeit wirksam wird und verhindert, daß das Fernsehgerät schlagartig herabfällt. Zu dem Zweck zusätzlich die Pufferfeder 29. Eine derartige oder auch anders wirkende Bremsvorrichtung ist bei den anschließend beschriebenen Ausführungsformen der Hebeeinrichtung ebenfalls vorgesehen, wenn auch nicht gezeichnet.4 and 6 show a shock absorber 28 which acts as a braking device in the event of a rope break or any other reasoned exceeding of the predetermined downward speed and prevents the television set from falling suddenly. For this purpose, the buffer spring 29 is also provided. A brake device of this type, or a brake with a different effect, is also provided in the embodiments of the lifting device described below, although not shown.

Die Hebeeinrichtungen nach Figur 7 bis 9 und nach Figur 10 bis 12 gehen zeichnerisch von Figur 6 aus. Wesentlicher Unterschied ist die Anordnung des Flaschenzuges in der Horizontalen, das heißt in Sehnenrichtung des Scherengestänges 18. Damit wird ermöglicht, den Tragboden 15 bis an den oberen Rand der Truhe 1 zu heben, ohne daß er dazu eine vertikale Mindesterstreckung, etwa die Kastenform gemäß Figur 2 erhält. Das Hindernis der Höhendifferenz der Rollen 23 und 25 der Figur 5 besteht hier nicht. Ohne irgendeine Veränderung am Scherengestänge läßt sich jetzt ein solch langer Tragboden verwirklichen, das Fernsehgerät 5 und den Videorecorder 7 auf dem Tragboden nebeneinander aufzustellen und dazu noch einen Plattenspieler, wenn nicht bevorzugt wird, den Videorecorder und den Plattenspieler übereinander anzuordnen. Im Sinne der Aufgabenstellung der Erfindung ist dies ein wesentlicher Nebenvorteil.The lifting devices according to FIGS. 7 to 9 and according to FIGS. 10 to 12 are illustrated in FIG. 6. The essential difference is the arrangement of the pulley in the horizontal direction, that is in a chordal direction of the scissors linkage 18. Thus, it is possible to lift the tray 15 up to the upper R and the chest 1 without having to a minimum vertical extension, such as the box shape according to Figure 2 receives. The obstacle to the height difference of the rollers 23 and 25 of FIG. 5 does not exist here. Without any change in the standard arm now such a long tray can be realized, the TV 5 and the VCR 7 on the T ragboden next to each other to set up plus a record player, if not preferable to place the VCR and the record player over the other. In the sense of the task of the invention, this is a substantial N advantage.

Die untere Sehne des Scherengestänges 18 ist gemäß Figur 9 der Abstand des Drehpunktes 30 des Stabpaares 17 vom Laufrollenpunkt 31 des Stabpaares 16. Diese Sehne entspricht im eingefahrenen Zustand des Scherengestänges etwa der Länge des Grundrahmens 32. Sie wird beim Übergang in den voll ausgefahrenen Zustand des Gestänges nur um etwa die halbe Hubhöhe kleiner. Folglich benötigt der Flaschenzug 33 bei gleic: großer Seilbelastung wie bei der Anordnung nach Figur 4 die doppelte Anzahl Rollen unter der Voraussetzung, daß die im Bereich des eingefahrenen Scherengestänges zur abnehmenden Hubhöhe rasch wechselnde Sehnenkraft nur teilweise vom Flaschenzug aufgenommen wird. Dies besorgt eine Entlastungsvorrichtung in Gestalt einer zwischen dem Tragboden 15 und dem Grundrahmen 32 eingefügten vertikalen Druckfeder 34. Durch sie kann es für den Flaschenzug bei besagter Rollenanzahl bleiben. Hubzeit, Windentrommel und Getriebemotor sind dann dieselben wie bei der Ausführung nach Figur 4 bis 6. Nur die Rollenanzahl ist doppelt so groß.According to FIG. 9, the lower chord of the scissor linkage 18 is the distance of the pivot point 30 of the pair of rods 17 from the roller point 31 of the pair of rods 16. This chord corresponds approximately to the length of the base frame 32 when the scissor linkage is retracted. It becomes the transition to the fully extended state of the The boom is only about half the height lower. Consequently, the pulley 33 requires the same number of pulleys for large rope loads as in the arrangement according to FIG. 4, provided that the tendon force which changes rapidly in the area of the retracted scissor linkage to the decreasing lifting height is only partially absorbed by the pulley. This is provided by a relief device in the form of a vertical compression spring 34 inserted between the supporting floor 15 and the base frame 32. It can remain with said number of rollers for the pulley system. Lifting time, winch drum and geared motor are then the same as in the embodiment according to FIGS. 4 to 6. Only the number of rollers is twice as large.

Die Kennlinie einer zylindrischen Schraubenfeder und die Kennlinie der anfänglichen Sehnenkraft sind leicht in Übereinstimmung zu bringen. Bei Übereinstimmung ergibt sich eine konstante Seilkraft im unteren Hubbereich, das heißt bei der Aufwärtsfahrt bis zu dem Punkt des Hubweges, in dem der Tragboden von der Feder abzuheben beginnt. In dem Zustand nach Figur 8 hat der Tragboden bereits abgehoben. Das Maß C ist der Federweg, während dem die Seilkraft konstant ist.The characteristic of a cylindrical coil spring and the characteristic of the initial tendon force are easy to match. If there is a match, there is a constant rope force in the lower lifting range, that is to say when driving upwards to the point of the lifting path at which the supporting floor begins to lift off the spring. In the state according to FIG. 8, the supporting floor has already taken off. The dimension C is the spring travel during which the rope force is constant.

Zur zeichnerischen Darstellung wird noch bemerkt, daß die Figur 9 den völlig eingefahrenen Zustand des Gestänges nur deshalb nicht zeigt, weil die Zeichnung dann zu unübersichtlich wäre. Ferner, die Befestigungsstelle des abgebrochen ge-zeichneten Endes 11'des Kunststoffseiles ist in den Figuren 7 bis 12 vernachlässigt worden.For the graphic representation, it is also noted that FIG. 9 does not show the fully retracted state of the linkage only because the drawing would then be too confusing. Furthermore, the attachment point of the broken end 11 ′ of the plastic rope has been neglected in FIGS. 7 to 12.

Der Flaschenzug 33 hat seinen Losrollensatz 35 im unteren Laufrollenpunkt 31 und seinen am Grundrahmen gelagerten Festrollensatz 36 in der Erstreckung der Scherensehn ter Belassung von Platz für die ffeder 34. Die in nicht gezeichneter Weise gegen Einknicken gesicherte zylindrische Schraubenfeder 34 steht gemäß Figur 7 im ausgefahrenen Scherenzustand so frei, daß sie bequem herausgehoben werden kann. Sie wird dann herausgenommen, wenn die Hebeeinrichtung lastlos ist, also im Leerlauf auf- oder abwärts fährt. Daher liegt die Feder 34 der Verpackungseinheit lose bei. Im Gegensatz zu dem Holm 22 der Figur 6 entfällt aber beim Einbau der Kompakteinheit in die Truhe ein Festschrauben des losen Teils und ein Ordnen der Seile.The block and tackle 33 has its loose roller set 35 in the lower roller point 31 and its fixed roller set 36 mounted on the base frame in the extension of the scissors tendon Leaving of space for the FF 34. The Eder in a manner not shown is secured against buckling cylindrical helical spring 34 is in accordance with Figure 7 in the extended state scissors so clear that it can be easily lifted out. It is then removed when the lifting device is idle, i.e. when it is idling up or down. Therefore, the spring 34 is loose in the packaging unit. In contrast to the spar 22 of FIG. 6, there is no need to screw the loose part and to arrange the cables when installing the compact unit in the chest.

In der Ausführungsform nach Figur 10 bis 12 ist ein sich nur angenähert horizontal erstreckender Flaschenzug 37 vorhanden. Ansonsten entspricht der Flaschenzug in der Anzahl Rollen und der Seilkraft dem Flaschenzug 33. Der Festrollensatz 36 ist nahe der Windentrommel 21 und nahe dem Drehpunkt 30 im Stabpaar 17 gelagert. Der Losrollensatz 35 ist im Scheitelpunkt 38 eines rechtwinkligen Winkelhebels 39 gelagert.In the embodiment according to FIGS. 10 to 12, there is an only approximately horizontally extending pulley 37. Otherwise, the pulley corresponds to the pulley 33 in terms of the number of rollers and the cable force. The fixed roller set 36 is mounted in the pair of rods 17 near the winch drum 21 and near the pivot point 30. The idler roller set 35 is mounted at the apex 38 of a right-angled angle lever 39.

Gemäß Figur 12 ist der Winkelhebel 39 im Laufrollenbereich des eingefahrenen Scherengestänges 18 angeordnet. Dabei liegt der Scheitelpunkt 38 so hoch, daß das auf den Losrollensatz 35 auflaufende Seil 11 die Stellfläche des rahmenförmigen Tragbodens 15 nahezu tangiert. Der eine, sich bis zum äußerstem Ende des Stabpaares 17 erstreckende Schenkel 40 endet in einer Rolle 41, die an der Unterseite des Stabpaares 17 entlangläuft. Der andere, sich abwärts erstreckende Schenkel 42 ist im Punkt 43 an der Unterseite des anderen Stabpaares 16 angelenkt.According to FIG. 12, the angle lever 39 is arranged in the roller area of the retracted scissor linkage 18. The apex 38 is so high that the rope 11 running onto the loose roller set 35 almost touches the footprint of the frame-shaped support base 15. One leg 40, which extends to the extreme end of the pair of rods 17, ends in a roller 41 which runs along the underside of the pair of rods 17. The other, downwardly extending leg 42 is articulated at point 43 on the underside of the other pair of rods 16.

Die Figur 12 läßt deutlich erkennen, daß die anfängliche Kraft des Flaschenzuges 37 nur wenig größer ist als die durch die Rolle 41 ausgeübte, der Last entsprechende vertikale Kraft. Eine Kraft in Sehnenrichtung des Gestänges 18 wird anfangs völlig umgangen. Wie die Figur 11 ausweist, geht die Resultierende der von den Punkten 41 und 43 auf das Scherengestänge ausgeübten Kräfte mit zunehmender Aufwärtsbewegung des Tragbodens 15 erst allmählich in die angenäherte Sehnenrichtung über. Dabei erreicht der Winkelhebel 39 gemäß Figur 10 schließlich eine Position, in der die nahe an den Scherenpunkt 44 herangekommene Rolle 41' in Bezug auf den Anfangszustand jenseits der vertikalen Mitte 45 der Punkte 38 und 43 liegt. Diese Position ist nicht etwa wie die eines Kniehebelpunktes streng funktionell zu werten. Sie soll nur die ungefähren geometrischen Verhältnisse der Größe und Anordnung des Winkelhebels bezeichnen. Die Bedingung wäre also auch schon erfüllt, wenn der Rollenpunkt 41 in der höchsten Gestängestellung statt jenseits der vertikalen Mitte in der vertikalen Mitte zu liegen kommt.FIG. 12 clearly shows that the initial force of the block and tackle 37 is only slightly greater than the vertical force which is exerted by the roller 41 and corresponds to the load. A force in the chord direction of the linkage 18 is initially completely avoided. As FIG. 11 shows, the resultant goes from points 41 and 43 the scissors linkage forces exerted with increasing upward movement of the T ragbodens 15 only gradually in the approximate chord-wise direction over. 10 finally reaches a position in which the roller 41 'which has come close to the scissors point 44 lies beyond the vertical center 45 of points 38 and 43 with respect to the initial state. This position is not strictly functional, like that of a toggle point. It should only describe the approximate geometric relationships of the size and arrangement of the bell crank. The condition would therefore already be fulfilled if the roller point 41 comes to lie in the highest linkage position in the vertical center instead of beyond the vertical center.

Die Hebeeinrichtung nach Figur 10 bis 12 ist eine vom Transportzustand (Kartonquader) aus sofort betriebsbereite Kompakteinheit. Der Montageaufwand des Möbeltischlers ist damit minimal.The lifting device according to FIGS. 10 to 12 is a compact unit which is immediately ready for operation from the transport state (box cuboid). The assembly effort of the cabinet maker is minimal.
