Definitions

  • the invention relates to an office table according to the preamble of claim 1.
  • Such an office table is known from DE-A-251162.
  • Office tables of this type are generally known and in use, which for ergonomic reasons or for setting the most favorable position to the user are generally not only height-adjustable but also incline-adjustable with respect to the table top. Because of the freedom of movement of the legs underneath the table top that is as free as possible, such tables are designed more or less like a desk today, i.e. the table top is only cantilevered to the seat side between two side bolsters, at the lower ends of which cantilevered footrests are kept which are shorter compared to the table top are located. In such previously known tables, it is now relatively difficult to assign the table top to the two side bolsters or the actual table frame, both adjustable in height and inclination, since this leads to relatively complex fittings which are to be arranged between the table top and frame.

It is important that the table top is aligned with the upper ends of the side cheeks in the side cheeks vertical slot guides are arranged on the inside for the table top or table top support joints.
  • the guide channels arranged in the side walls are also used, in which simply compression springs sit under the slide rods.
  • the "normal position" of the table top thus corresponds to its maximum position, which does not require any special stop limitation, because the articulated processes on the slide rods, to which the support struts for the table top are articulated, ensure this.

Description

Die Erfindung betrifft einen Bürotisch gemäß Oberbegriff des Anspruches 1. Ein derartiges Bürotisch ist durch die DE-A-251162 bekannt.The invention relates to an office table according to the preamble of claim 1. Such an office table is known from DE-A-251162.

Derartige Bürotische sind allgemein bekannt und in Benutzung, die aus ergonomischen Gründen bzw. für eine Einstellung der günstigsten Position zum Benutzer in der Regel nicht nur höhensondern auch neigungseinstellbar bezüglich der Tischplatte ausgebildet sind. Wegen der zu fordernden möglichst unbehinderten Beinbewegungsfreiheit unterhalb der Tischplatte sind heute derartige Tische mehr oder weniger pultartig ausgebildet, d.h., die Tischplatte ist zur Sitzseite stärker auskragend lediglich zwischen zwei Seitenwangen angeordnet, an deren unteren Enden sich entsprechend auskragende, aber im Vergleich zur Tischplatte kürzergehaltene Fußstützen befinden. Bei derartig vorbekannten Tischen ist es nun relativ schwierig, die Tischplatte sowohl höhen- als auch neigungsverstellbar den beiden Seitenwangen bzw. dem eigentlichen Tischgestell zuzuordnen, da dies zu relativ aufwendigen Beschlägen führt, die zwischen Tischplatte und Gestell anzuordnen sind.Office tables of this type are generally known and in use, which for ergonomic reasons or for setting the most favorable position to the user are generally not only height-adjustable but also incline-adjustable with respect to the table top. Because of the freedom of movement of the legs underneath the table top that is as free as possible, such tables are designed more or less like a desk today, i.e. the table top is only cantilevered to the seat side between two side bolsters, at the lower ends of which cantilevered footrests are kept which are shorter compared to the table top are located. In such previously known tables, it is now relatively difficult to assign the table top to the two side bolsters or the actual table frame, both adjustable in height and inclination, since this leads to relatively complex fittings which are to be arranged between the table top and frame.

Aufgrund der pultartig dem Gestell zugeordneten Tischplatte bedarf diese zur auskragenden Seite hin einer ausreichenden Unterstützung, wenn die Tischplatte in jeder Höhen- und Neigungsstellung stabil sein soll.Due to the table top assigned to the frame, this requires sufficient support towards the cantilevered side if the table top is to be stable in any height and inclination position.

Bei den bekannten Seitenwangen für derartige Tische handelt es sich in der Regel um zweiteilig teleskopartig ausgebildete, im Querschnitt flache Profilrohre, von denen die nach oben ausziehbaren Teile durch eine geeignete Traverse verbunden sein müssen, um an dieser die Stütz- und Kippbeschläge für die Neigungseinstellung der Tischplatte ansetzen zu können, da dafür die relativ dünnwandigen Profilrohre der Seitenwangen nicht ausgenutzt werden können, in denen zwecks Höhenverstellbarkeit bspw. Verstellspindeln angeordnet sind, die untereinander verbunden sein müssen, um von einer Betätigungskurbel aus beiden Seitenwangen gleichmäßig verstellen zu können.The known side bolsters for such tables are generally two-part telescopically shaped, cross-sectionally flat profile tubes, of which the parts which can be pulled out upwards must be connected by a suitable crossmember in order for the support and tilting fittings for the inclination adjustment of the To be able to attach the table top, since the relatively thin-walled profile tubes of the side cheeks cannot be used, in which, for the purpose of height adjustability, for example, adjusting spindles are arranged, which have to be connected to one another in order to be able to adjust evenly from an operating crank from both side cheeks.

Der Erfindung liegt die Aufgabe zugrunde, einen Bürotisch der eingangs genannten Art dahingehend zu verbessern, daß die sowohl für die Höhen- als auch für die Neigungsverstellung der Tischplatte erforderlichen Elemente einfach zu verwirklichen und die Verstellvorgänge einfach zu handhaben sind und zwar mit der Maßgabe, die Seitenwangen nicht als zweiteilige teleskopartig verschiebliche Profilrohre ausbilden zu müssen und auf mechanisch aufwendige Kippbeschläge zur Neigungsverstellung der Tischplatte verzichten zu können.The invention has for its object to improve an office table of the type mentioned in that the elements required for both the height and the inclination adjustment of the table top are easy to implement and the adjustment processes are easy to handle, with the proviso that No need to design side walls as two-part telescopically displaceable profile tubes and to be able to do without mechanically complex tilting fittings for tilting the table top.

Diese Aufgabe ist mit einem Bürotisch der eingangs genannten Art nach der Erfindung durch die im Kennzeichen des Anspruches 1 angeführten Merkmale gelöst. Vorteilhafte Weiterbildungen ergeben sich nach den abhüngigen Ansprüchen 2-11.This object is achieved with an office table of the type mentioned according to the invention by the features stated in the characterizing part of claim 1. Advantageous further developments result from the dependent claims 2-11.

Diese Lösung stellt praktisch ein in sich verstellbares Dreieck dar, dessen Seiten vom Schieber, von der Tischplattenstützstrebe und von der Tischplatte selbst bzw. dem Tischplattenträger gebildet werden, wobei das ganze Dreieck mit seinem Schieberteil in der betreffenden Seitenwange höhenverstellbar ist, d.h. die Stützstreben und die Tischplatte nehmen gemeinsam an der Höhenverstellung mit teil; nicht aber die Seitenwangen, von denen lediglich ein kleiner Teil als Führungskanal für die Schieberstangen ausgebildet ist, was noch näher erläutert wird. Wesentlich ist dabei, daß die Tischplatte in Höchststellung mit den oberen Enden der Seitenwangen fluchtet in den Seitenwangen sind innenseitig vertikale Schlitzführungen für die Tischplatten- bzw. Tischplattenträgergelenke angeordnet. Für die Druckbelastung der Schieberstangen sind ebenfalls die in den Seitenwangen angeordneten Führungskanäle ausgenutzt, in denen einfach Druckfedern unter den Schieberstangen sitzen. Die "Normalstellung" der Tischplatte entspricht also ihrer Höchststellung, die keiner besonderen Anschlagbegrenzung bedarf, weil dafür die an den Schieberstangen sitzenden Gelenkfortsätze sorgen, an denen die Stützstreben für die Tischplatte angelenkt sind. Durch die erfindungsgemäße Ausbildung ist auch die vorteilhafte Möglichkeit geschaffen, einen sich längs der hinteren Tischplattenkante erstreckenden Kabelkanal, deren Anbringung an solchen Tischen in der Regel gefordert wird, vorteilhaft an den oberen Enden der Schieberstangen anbringen zu können, der somit an einer etwaigen Höhenverstellung teilnimmt und in jeder Stellung der Tischplatte bündig zugeordnet bleibt. Ausgehend von der "Normalstellung", erfolgt also eine Höhenverstellung der Tischplatte beim erfindungsgemäßen Bürotisch immer zwischen dieser Normalstellung und einer möglichen Tiefststellung, die durch den unteren Rand der beteiligten Schlitze in den Seitenwangen definiert ist.This solution practically represents an adjustable triangle, the sides of which are formed by the slider, by the tabletop support strut and by the tabletop itself or the tabletop support, the entire triangle with its slider part being height-adjustable in the side cheek in question, i.e. the support struts and the table top take part in the height adjustment; but not the side walls, of which only a small part is designed as a guide channel for the slide rods, which will be explained in more detail. It is important that the table top is aligned with the upper ends of the side cheeks in the side cheeks vertical slot guides are arranged on the inside for the table top or table top support joints. For the pressure loading of the slide rods, the guide channels arranged in the side walls are also used, in which simply compression springs sit under the slide rods. The "normal position" of the table top thus corresponds to its maximum position, which does not require any special stop limitation, because the articulated processes on the slide rods, to which the support struts for the table top are articulated, ensure this. The design according to the invention also creates the advantageous possibility of advantageously being able to attach a cable duct extending along the rear edge of the table top, the attachment of which is generally required on such tables, to the upper ends of the slide rods, which thus participates in any height adjustment and remains flush with the table top in every position. Starting from the "normal position", the table top in the office table according to the invention is therefore always adjusted between this normal position and a possible lowest position, which is defined by the lower edge of the slits involved in the side cheeks.

Der erfindungsgemäße Bürotisch und vorteilhafte Weiterbildungsformen werden nachfolgend anhand der zeichnerischen Darstellung von Ausführungsbeispielen näher erläutert.The office table according to the invention and advantageous forms of further training are explained in more detail below with reference to the drawing of exemplary embodiments.

Wie aus Fig. 1 erkennbar, besteht der Bürotisch aus einem aus zwei untereinander verbundenen Seitenwangen 1 gebildeten Gestell 33, an dem die Tischplatte 7 höhenund neigungseinstellbar angeordnetist. In den Führungskanälen 2 der Seitenwangen 1 sind dabei höhenverstell- und fixierbar Schieberstangen 4 gelagert, an deren oberen Enden 5 die Tischplatte 7 angelenkt ist und an denen schwenkbar Tischplattenstützträger 11 angeordnet sind, deren tischplattenseitigen Enden 12 in mindestens zwei Stellungen mit der Tischplatte 7 fixierbar ausgebildet sind. Im dargestellten Ausführungsbeispiel ist die Anlenkung der Tischplatte 7 nicht direkt an den Schieberstangen und den Stützträgern 11 vorgesehen, sondern zwischen diesen Elementen und der Tischplatte 7 ist ein Tragrahmen 15 als Tischplattenträger 8 angeordnet, auf bzw. an dem die Tischplatte 7 in geeigneter Weise, in ihrer Ebene verbleibend, verschieblich gelagert ist, um auf diese Weise den vorteilhaft mit an den Schieberstangen 4 befestigten Kabelkanal 17 zugänglich machen zu können. Die Schieberstangen 4 sind, wie deutlicher aus Fig. 12 erkennbar, mit Klemmbacken 3 und mit Klemmschrauben 3' versehen, die gemäß Fig. 12 die Schieberstangen 4 im Bereich eines Schlitzes 4' durchgreifen. Jede Schieberstange 4 ist dabei in den Führungskanälen 2 mittels nach unten abgestützter Druckfeder 13 elastisch gelagert, wodurch bei gelösten Klemmschrauben 3' die Tischplatte 7 in gewünschte Stellung nach unten gedrückt und in dieser durch Feststellen der beiden Klemmschauben 3' fixiert werden kann. Vorteilhaft sind ferner die Schieberstangen 4 und die betreffenden Wände der Führungskanäle 2 jeweils mit mehreren Schnappverrastungselementen 14 ausgestattet, die in ausgewählten Stellungen eine vorläufige Verrastung der entsprechend niedergedrückten Tischplatte 7 ermöglichen, die dann durch Festsapnnen der Klemmschrauben 3' gesichert wird. Die Tischplattenstützträger 11, die nicht zwingend die dargestellte Bogenform aufweisen müssen, sind an den Schieberstangen 4 gelenkig gelagert und mit ihren tischplattenseitigen Enden 12 verschieblich und schwenkbar an der Tischplatte 7 bzw. am Tragrahmen 15, wie im Ausführungsbeispiel dargestellt, befestigt. Hierfür sind, wie aus Fig. 3 ersichtlich (links), kleine exzenterartige Festspannelemente 16 geeignet, mit denen ein Schraubenkopf gegen die geschlitzte Anlenklasche 12' am Ende jeden Tischplattenstützträgers 11 festgespannt werden kann. Da sich die Anlenkstelle jedes Stützträgers 11 bei Höhenverstellung der Schieberstangen 4 mitbewegt, müssen natürlich die Seitenwangen 1 in diesem Bereich mit einem entsprechend langen Schlitz 10 versehen sein. Gleiches gilt für die Gelenke 6 am oberen Ende jeder Schieberstange, an dem die Tischplatte 7 bzw. der Tragrahmen 15 angelenkt ist. Diese seitlichen Schlitzführungen an den Seitenwangen 1 sind mit 29 bezeichnet.As can be seen from Fig. 1, the office table consists of a frame 33 formed from two interconnected side walls 1, on which the table top 7 is arranged to be adjustable in height and inclination. In the guide channels 2 of the side walls 1, height-adjustable and fixable slide rods 4 are mounted, on the upper ends 5 of which the table top 7 is articulated and on which pivotable table top support supports 11 are arranged, the table top ends 12 of which are designed to be fixable with the table top 7 in at least two positions are. In the illustrated embodiment, the articulation of the table top 7 is not provided directly on the slide rods and the support beams 11, but between these elements and the table top 7, a support frame 15 is arranged as a table top support 8, on or on which the table top 7 in a suitable manner, in their level remaining, is slidably mounted in order to be able to access the cable duct 17, which is advantageously fastened to the slide rods 4. As can be seen more clearly from FIG. 12, the slide rods 4 are provided with clamping jaws 3 and with clamping screws 3 'which, according to FIG. 12, pass through the slide rods 4 in the region of a slot 4'. Each slide rod 4 is elastically supported in the guide channels 2 by means of a compression spring 13 supported downwards, so that when the clamping screws 3 'are loosened, the table top 7 can be pressed down into the desired position and can be fixed in it by locking the two clamping screws 3'. Furthermore, the slide rods 4 and the walls of the guide channels 2 are advantageously each equipped with a plurality of snap-locking elements 14 which, in selected positions, enable the correspondingly depressed table top 7 to be temporarily locked, which is then secured by tightening the clamping screws 3 '. The tabletop support beams 11, which do not necessarily have to have the arched shape shown, are articulated on the slide rods 4 and are slidably and pivotably attached to the table top 7 ends 12 on the table top 7 or on the support frame 15, as shown in the exemplary embodiment. For this purpose, as can be seen from FIG. 3 (left), small eccentric clamping elements 16 are suitable, with which a screw head can be clamped against the slotted link bracket 12 'at the end of each tabletop support bracket 11. Since the articulation point of each support bracket 11 also moves when the slide rods 4 are adjusted in height, the side cheeks 1 must of course be provided with a correspondingly long slot 10 in this area. The same applies to the joints 6 at the upper end of each slide rod to which the table top 7 or the support frame 15 is articulated. These lateral slot guides on the side cheeks 1 are designated 29.

Alternativ kann statt der Festspannelemente 16 gemäß Fig. 3 (linke Seite) ein Verrastungsgestänge 35 (rechte Seite in Fig. 3) mit einem Stellhebel 36 vorgesehen werden, mit dem dann gleichzeitig die Enden 12 beider Stützträger 11 fixiert werden können.Alternatively, instead of the clamping elements 16 according to FIG. 3 (left side), a locking linkage 35 (right side in FIG. 3) can be provided with an adjusting lever 36, with which the ends 12 of both support brackets 11 can then be fixed simultaneously.

Bei der Ausführungsform nach Fig. 5 sind die Flankenwandungsteile 18 der Seitenwangen 1 mit einem zurückgesetzten Wandungsteil versehen, wodurch außen an jeder Seitenwange 1 eine Wangenausnehmung 19 entsteht, in der der jeweilige Stützträger 11 geführt ist und zwar, wie beschrieben, mittels der in der Seitenwange 1 angeordneten verstell- und fixierbaren Schieberstange 4. Innerhalb des langlochartigen Schlitzes 10' kann dabei eine Rolle 37 angeordnet sein, die auf einem Verbindungszapfen zwischen wangenseitigen Ende 20 des Stütztträgers 11 und Schieberstange 4 sitzt. Die Fixierung des anderen tischplattenseitigen Endes 12 der Stützträger 11 an der Tischplatte 7 oder am Tragrahmen 15 erfolgt in der einen oder anderen Art, wie zu Fig. 3 beschrieben.In the embodiment according to FIG. 5, the flank wall parts 18 of the side cheeks 1 are provided with a recessed wall part, as a result of which a cheek recess 19 is formed on the outside of each side cheek 1, in which the respective support bracket 11 is guided, as described, by means of those in the side cheek 1 arranged adjustable and fixable slide rod 4. Inside the slot-like slot 10 ', a roller 37 can be arranged, which sits on a connecting pin between the cheek-side end 20 of the support bracket 11 and the slide rod 4. The other end 12 of the support bracket 11 on the table top is fixed on the table top 7 or on the support frame 15 in one way or another, as described for FIG. 3.

Wie aus den Fig. 1 und 3 erkennbar, ist die Tischplatte 7 vorteilhaft auf einem Tragrahmen 15 und der Kabelkanal 17 an diesem bzw. den Schieberstangen 4 angeordnet, wobei die Tischplatte 7 parallel zum Tragrahmen 15 verschieblich an diesem und in Endstellung an dem trogartig ausgebildeten und nach oben offenen Kabelkanal 17 überdeckend gelagert ist. Unter der Tischplatte 7 ist gemäß Fig. 6, 7 auf jeder Seite mindestens ein mit Rolle 21 versehener Beschlag 22 vorgesehen, wobei die jeweilige Rolle 21 am Tragrahmen 15 geführt und der Tragrahmen 15 dafür vorteilhaft aus Hohlprofilen 23 gebildet ist. Die die Tischplattenführung bildenden Hohlprofile 23 sind mit seitlichen Profileintiefungen 24 versehen (Fig. 8). In diese seitlichen Profileintiefungen 24 greifen- diemit ihrer Drehachse senkrecht zur Tischplatte 7 angeordneten Rollen 21 ein. Diese Eintiefungen 24 werden an den die Seitenholme des Tragrahmens 15 bildenden Hohlprofilen 23 einfach durch entsprechende Prägeverformung ausgebildet. Durch diese Ausbildung ergibt sich ein räumlich wenig auftragendes Gebilde aus Tischplatte 7 und Tragrahmen 15, wobei vorteilhaft die Tischplatte 7 bis auf die kabelkanalseitige Kante 7" (Fig. 9) mit einem Randprofil 7' versehen ist, das den Tragrahmen 15, wie aus Fig. 7 erkennbar, seitlich überdeckt.As can be seen from FIGS. 1 and 3, the table top 7 is advantageously arranged on a support frame 15 and the cable duct 17 on this or the slide rods 4, the table top 7 being displaceable parallel to the support frame 15 on this and in the end position on the trough-shaped and cable duct 17 which is open at the top is mounted so as to overlap. 6, 7, at least one fitting 22 provided with roller 21 is provided under the table top 7, the respective roller 21 being guided on the supporting frame 15 and the supporting frame 15 being advantageously formed from hollow profiles 23 for this purpose. The hollow profiles 23 forming the table top guide are provided with lateral profile recesses 24 (FIG. 8). The rollers 21 arranged perpendicularly to the table top 7 engage in these lateral profile recesses 24 with their axis of rotation. These recesses 24 are formed on the hollow sections 23 which form the side rails of the support frame 15 simply by appropriate stamping deformation. This configuration results in a space-saving structure consisting of table top 7 and support frame 15, with the advantage that the table top 7 is provided with an edge profile 7 'apart from the cable channel-side edge 7 "(FIG. 9), which supports the support frame 15, as shown in FIG 7 recognizable, covered laterally.

Wie aus Fig. 10, 11 ersichtlich, besteht eine vorteilhafte und bevorzugte Ausführungsform darin, daß am oberen Ende jeder Seitenwange 1 ein Kurbeltrieb 25 angeordnet ist und die beiden Kurbeltriebe 25 mit einer gemeinsamen, am Gestell 33 bzw. einer Gestelltraverse 30 gelagerten Drehachse 26 verbunden sind, wobei das Stellglied 27 jedes Kurbeltriebes 25 mit dem Tischplattengelenk 6 in einer vertikalen Schlitzführung 29 der Seitenwange 1 geführt ist. In Rücksicht auf eine raumsparende Anordnung und inbezug auf die vertikale Verstellbewegung der Gelenke 6 ist das Stellglied 27 mit einem abgeknickten, kurbelfernen Ende 31 versehen, an dem das jeweilige Gelenk 6 angeordnet ist. Sofern lediglich die beiden Kurbeltriebe für die Höheneinstellung und eine Parallelführung zur Anwendung kommen, was grundsätzlich möglich wäre, ist zumindest ein Kurbeltrieb 25 in unterschiedliche Stellungen in bezug auf das Gestell 33 fixierbar ausgebildet, was nicht besonders dargestellt ist, da sich für derartige Fixierungen die unterschiedlichsten Möglichkeiten (Spannschrauben, Klemmschrauben, Verrastungselemente od. dgl.) anbieten und zwar ebenfalls an den unterschiedlichsten Stellen, d.h., entweder an der der Drehachse 26 selbst oder am Stellglied 27 bzw. dem Kurbelarm oder im Bereich der Schlitzführung 29.As can be seen from FIGS. 10, 11, an advantageous and preferred embodiment consists in that a crank mechanism 25 is arranged at the upper end of each side cheek 1 and the two crank mechanisms 25 are connected to a common axis of rotation 26 mounted on the frame 33 or a frame traverse 30 are, the actuator 27 of each crank mechanism 25 is guided with the table top joint 6 in a vertical slot guide 29 of the side wall 1. In consideration of a space-saving arrangement and in relation to the vertical adjustment movement of the Joints 6, the actuator 27 is provided with a bent end 31 remote from the crank, on which the respective joint 6 is arranged. If only the two crank drives are used for the height adjustment and a parallel guide, which would be possible in principle, at least one crank drive 25 is designed to be fixable in different positions with respect to the frame 33, which is not shown in particular since the most varied of such fixings Offer possibilities (clamping screws, clamping screws, latching elements or the like) and also at the most varied of locations, ie either on the axis of rotation 26 itself or on the actuator 27 or the crank arm or in the region of the slot guide 29.

Es kann auch jedem Kurbeltrieb 25 eine Druckfeder 32, wie bspw. dargestellt, zugeordnet werden, die den Kurbeltrieb immer in Höchststellung drückt, wobei, sofern kein anderes Verstellbetätigungselement vorgesehen ist (bspw. Stellhebel an der Außenflanke einer der Seitenwangen 1 mit der Drehachse 4 in Verbindung stehend), die Höhenverstellung einfach durch Drukkausübung auf die Tischplatte 7 bzw. den Tragrahmen 15 bewirkt und die neu eingenommene Höheneinstellung in geeigneter Weise mit entsprechenden Elementen fixiert wird. Bevorzugt wird jedoch das Ausführungsbeispiel nach Fig. 11, bei dem der Bürotisch derart ausgebildet ist, daß die Tischplatten- bzw. Tischplattentragrahmengelenke 6 jedes Kurbeltriebes 25 mit der in den betreffenden Seitenwange 1 angeordneten Schiebrstange 4 gelenkig verbunden ist.A compression spring 32, as shown, for example, can also be assigned to each crank mechanism 25, which always pushes the crank mechanism into the highest position, whereby, unless another adjustment actuating element is provided (e.g. adjusting lever on the outer flank of one of the side walls 1 with the axis of rotation 4 in Connected), the height adjustment simply by exerting pressure on the table top 7 or the support frame 15 and the newly adopted height adjustment is fixed in a suitable manner with appropriate elements. However, the embodiment according to FIG. 11 is preferred, in which the office table is designed in such a way that the table top or table top support frame joints 6 of each crank mechanism 25 are connected in an articulated manner to the push rod 4 arranged in the side cheek 1 in question.

Bei dieser Ausführungsform haben die beiden durch die Drehachse 26 verbundenen Kurbeltriebe 25 lediglich eine Parallelführungsfunktion. Vorteilhaft sind aber die Kurbeltriebe auch, wie ohne weiteres vorstellbar, für die Höhenverstellung selbst ausnutzbar, wenn nämlich mit geeigneten Mitteln an der die beiden Kurbeltriebe 25 starr verbindenden Drehachse 26 dafür gesorgt wird, daß man diese verdrehen kann. Sofern, wie vorerwähnt, Fixierungselemente an mindestens einem der Kurbeltriebe 25 angeordnet sind, können die vorbeschriebenen Fixierungselemente an den Schieberstangen 4 entfallen. Gleiches gilt für die Druckfedern 13, wenn an den Kurbeltrieben 25 Druckfedern 32 angeordnet sind. Für die Höhenverstellung der Tischplatte 7 genügen 10 bis 12 cm, und entsprechend lang sind alle Schlitze bzw. Schlitzführungen ausgebildet.In this embodiment, the two crank drives 25 connected by the axis of rotation 26 only have a parallel guide function. However, the crank mechanisms are also advantageous, as is readily conceivable, for the height adjustment itself, namely if suitable means are provided on the axis of rotation 26 rigidly connecting the two crank mechanisms 25 so that they can be rotated. If, as mentioned above, fixing elements are arranged on at least one of the crank drives 25, the above-described fixing elements on the slide rods 4 can be omitted. The same applies to the compression springs 13 if 25 compression springs 32 are arranged on the crank drives. For the height adjustment of the table top 7, 10 to 12 cm are sufficient, and all slots or slot guides are correspondingly long.
