Description

Die vorliegende Erfindung betrifft einen einstellbaren Tisch, insbesondere einen vierfüßigen Tisch.The present invention relates to an adjustable table, in particular a four-legged table.

Tische, insbesondere vierfüßige Tische, beispielsweise die weit verbreiteten und einen eigenen Standard darstellenden transportablen Bistro-Tische mit vier gebogenen Stahlrohr-Beinen, von denen zwei seitlich klappbar sind, mit ebenfalls klappbaren, meist runden Tischplatten von beispielsweise 80 cm Durchmesser und mit Tisch-Höhen von ca. 70 cm und ca. 110 cm, werden häufig an einem anderen Standort mit jeweils anderem Bodenrelief aufgestellt und wackeln fast immer auf nahezu jedem Untergrund, wenn dieser auch nur geringe Unebenheiten hat, weil dann eines der vier Beine keinen Bodenkontakt hat, mit der Folge, dass der Tisch bei Gebrauch nahezu jedes Mal heftig ruckartig wackelt und dabei Getränke überschwappen lässt oder die Einnahme von Mahlzeiten zu einem ärgerlichen Balance-Akt geraten lässt.Tables, especially four-legged tables, for example the widespread transportable bistro tables that represent a standard of their own with four curved tubular steel legs, two of which can be folded to the side, with also foldable, mostly round table tops, for example 80 cm in diameter and with table heights of approx. 70 cm and approx. 110 cm, are often set up in a different location with a different floor relief and almost always wobble on almost any surface, even if it has only slight unevenness, because one of the four legs is then not in contact with the ground As a result, the table jerks violently almost every time it is used, causing drinks to spill over or taking meals into an annoying balancing act.

Die üblichen Gegenmaßnahmen, beispielsweise Unterlegen kleiner Gegenstände oder Verstellen von Ausgleichs-Schrauben an einem Tisch-Fuß, sind meist unzureichend, unzumutbar wegen Schmutz an den Tisch-Füßen oder sind mangels Material unmöglich, auf jeden Fall aber sind sie lästig und unterbleiben vielfach aus mindestens einem dieser Gründe.The usual countermeasures, for example placing small objects underneath or adjusting compensating screws on a table foot, are mostly inadequate, unreasonable because of dirt on the table feet or are impossible due to a lack of material, but in any case they are annoying and often do not occur at least one of those reasons.

Wirte, Kellner und Gäste sind weltweit täglich mit diesem Problem konfrontiert.Hosts, waiters and guests around the world are confronted with this problem every day.

Insbesondere für vollständig klappbare, mobile Tische existiert bisher keine zufriedenstellende Lösung des Wackel-Problems.In particular for completely foldable, mobile tables, there has so far been no satisfactory solution to the wobbling problem.

Die WO 2006/101279 A1 offenbart einen Tisch, bei dem die Höhe einer Oberseite eines Tisches gemäß der Größe eines Benutzers eingestellt werden kann, um den Komfort des Benutzers zu verbessern. Der Tisch umfasst ein erstes Bein, das mit einer Oberseite eines Tisches verbunden ist, und ein zweites Bein zum Tragen der horizontal zu haltenden Oberseite, wobei das zweite Bein mit dem ersten Bein verbunden ist und in Längsrichtung ausziehbar und zusammenziehbar ist. Ein Verriegelungsabschnitt ist entweder am ersten Bein oder am zweiten Bein vorgesehen, um den Beinabschnitt mittels eines Betätigungshebels zu verriegeln und freizugeben. Mit dieser Struktur kann der Tisch für verschiedene Größen von Benutzern zu Hause, in Büros oder in Schulen verwendet werden.The WO 2006/101279 A1 discloses a table in which the height of a top of a table can be adjusted according to the size of a user to improve the comfort of the user. The table includes a first leg connected to a top of a table and a second leg for supporting the horizontally to be held top, wherein the second leg is connected to the first leg and can be extended and contracted in the longitudinal direction.

Die beweglichen Füße sind von den unbeweglichen Tischbeinen getrennt und bilden mit Holm und Schaft eine auf und ab bewegliche Baugruppe für den Niveau-Ausgleich.The clamping mechanism locks the movable feet by means of a force fit between the vertical shaft and the immovable table legs. The movable feet are separated from the immovable table legs and, together with the spar and shaft, form an up and down assembly for level compensation.

Der erfindungsgemäße Tisch erfreut Wirte, Kellner und Gäste, indem er Schluss macht mit lästigen Wackeleien von Tischen, die bisher zu vielerlei Verdruss Anlass gaben.The table according to the invention delights innkeepers, waiters and guests by putting an end to annoying wobbling of tables, which up to now have given rise to all sorts of annoyance.

Die vorliegende Erfindung gibt ihren Anwendern Gelegenheit, transportable, vollständig klappbare Tische bereits während des Aufstellens Boden-Unebenheiten ausgleichen zu lassen, bis diese Tische eine wackelfreie Position eingenommen haben, um sie dann mit einer Handbewegung in dieser Position zu fixieren.The present invention gives its users the opportunity to have transportable, completely foldable tables compensate for unevenness in the floor while they are being set up, until these tables have assumed a wobble-free position, in order to then fix them in this position with one movement of the hand.

Einander entsprechende Merkmale sind in allen Figuren durch gleiche Bezugszeichen gekennzeichnet.Features that correspond to one another are identified by the same reference symbols in all figures.

Lage- und Orientierungsangaben sind auf eine Gebrauchslage des Tisches bezogen.Position and orientation information are based on a position of use of the table.

In Figur 1a ist schematisch ein Tisch 1, insbesondere ein Bistro-Tisch mit vier Füßen 4, 5, 8, 9, dargestellt. In der Abbildung steht der Tisch 1 übertrieben schief um den nachteiligen Einfluss einer Boden-Unebenheit B, auf dem der Fuß 9 des Tischs 1 steht, zu verdeutlichen. Figur 1a zeigt den Tisch 1 mit zwei seitlich klappbaren Beinen 2, 3 und deren Füßen 4, 5, sowie mit zwei diagonal einander gegenüber befindlichen starren Beinen 6, 7, denen die davon getrennten vertikal beweglichen Füße 8, 9 zugeordnet sind, welche an einem Holm 10 befestigt sind, an welchem ein vertikaler Schaft 11 befestigt ist mit einer oben angebrachten Führung 12, die zwischen den Beinen 6, 7 angeordnet ist.In Figure 1a a table 1, in particular a bistro table with four feet 4, 5, 8, 9, is shown schematically. In the figure, the table 1 is exaggeratedly crooked in order to illustrate the disadvantageous influence of an unevenness in the floor B on which the foot 9 of the table 1 stands. Figure 1a shows the table 1 with two laterally foldable legs 2, 3 and their feet 4, 5, as well as with two diagonally opposite rigid legs 6, 7, to which the vertically movable feet 8, 9 separated therefrom are assigned, which are attached to a spar 10 are attached, to which a vertical shaft 11 is attached with a guide 12 attached above, which is arranged between the legs 6, 7.

Füße 8, 9, Holm 10, Schaft 11 und Führung 12 sind verbunden zu einer gemeinsam auf und ab beweglichen Baugruppe.Feet 8, 9, spar 10, shaft 11 and guide 12 are connected to form an assembly that can move up and down together.

Weiter sind Halterungen 13, 14 dargestellt, welche die seitlich klappbaren Beine 2, 3 mit den starren Beinen 6, 7 verbinden. Die Halterungen 13, 14 gestatten, für Transportzwecke die Beine 2, 3 seitlich so zu klappen, dass deren Füße 4, 5 an den vertikal beweglichen Füßen 8, 9 etwa parallel anliegen, statt quer und sperrig von diesen kreuzförmig abzustehen. Diese Klapp-Mechanik ist seit langem Standard bei Tischen dieser Art, um kompakte Abmessungen beim Transport zu erzielen.Holders 13, 14 are also shown, which connect the laterally foldable legs 2, 3 to the rigid legs 6, 7. The brackets 13, 14 allow the legs 2, 3 to be folded sideways for transport purposes so that their feet 4, 5 rest approximately parallel on the vertically movable feet 8, 9 instead of protruding cross-shaped and bulky from them. This folding mechanism has long been standard for tables of this type in order to achieve compact dimensions during transport.

Führung 12 lässt den Holm 10 vertikal zwischen den Beinen 6, 7 gleiten, sobald unebener Untergrund beim Aufstellen des Tischs 1 erfordert, dass Holm 10 und die daran befestigten Füße 8, 9 sich entweder gemeinsam aufwärts oder abwärts bewegen, um zu erreichen, dass alle vier Füße 4, 5, 8, 9 gleichzeitig Bodenkontakt haben.Guide 12 allows the bar 10 to slide vertically between the legs 6, 7 as soon as uneven ground when setting up the table 1 requires that the bar 10 and the feet 8, 9 attached to it move either up or down together in order to achieve that all four feet 4, 5, 8, 9 have contact with the ground at the same time.

Auf einem tragenden Gestell von Tisch 1, welches hauptsächlich die Beine 2, 3, 6, 7 und die zugehörigen Füßen 4, 5, 8, 9 umfasst, befindet sich eine Tischplatte 15.A table top 15 is located on a supporting frame of table 1, which mainly comprises legs 2, 3, 6, 7 and the associated feet 4, 5, 8, 9.

Figur 1a zeigt den Tisch 1 in wackeliger Aufstellung auf unebenem Boden. Die Tischplatte 15 von Tisch 1 würde zusammen mit dem gesamten Tisch-Untergestell wegen der Boden-Unebenheit B unter Fuß 9 entweder zum Fuß 5 oder zum Fuß 4 hin kippen. Außerdem wäre der Tisch 1 relativ stark zum Fuß 8 hin geneigt. Figure 1a shows the table 1 in a shaky position on uneven ground. The table top 15 of table 1, together with the entire table underframe, would tilt either towards the foot 5 or towards the foot 4 because of the uneven floor B under foot 9. In addition, the table 1 would be inclined relatively sharply towards the foot 8.

Figur 1b zeigt den Tisch 1 nach erfolgtem Ausgleich der Boden-Unebenheit B unter Fuß 9 in wackelfreier Aufstellung, welche durch vertikale Bewegung der aus Füßen 8, 9, Holm 10, Schaft 11 und Führung 12 bestehenden Baugruppe bewirkt wurde, erkennbar in Figur 1b daran, dass der Abstand zwischen Führung 12 und Halterung 14 kleiner ist als in Figur 1a. Figure 1b shows the table 1 after the unevenness of the floor B under foot 9 has been leveled out in a wobble-free setup, which was caused by vertical movement of the assembly consisting of feet 8, 9, spar 10, shaft 11 and guide 12, recognizable in FIG Figure 1b that the distance between guide 12 and bracket 14 is smaller than in Figure 1a .

Die Beine 2, 3, 6 und 7 stehen nicht exakt senkrecht, sondern immer noch relativ leicht nach links vorn zum Fuß 8 hin geneigt, jedoch ist die Neigung der Beine 2, 3, 6 und 7 nur noch halb so stark wie in dem Zustand, den Figur 1a zeigt.The legs 2, 3, 6 and 7 are not exactly vertical, but still inclined relatively slightly to the left in front of the foot 8, but the inclination of the legs 2, 3, 6 and 7 is only half as strong as in this state , the Figure 1a shows.

Entsprechend ist die Platte 15 von Tisch 1 nicht exakt horizontal ausgerichtet sondern ebenfalls, - wie die Beine 2, 3, 6 und 7, leicht zum Fuß 8 hin geneigt, jedoch nur halb so stark wie in Figur 1a dargestellt.Correspondingly, the plate 15 of table 1 is not aligned exactly horizontally but also - like the legs 2, 3, 6 and 7 - slightly inclined towards the foot 8, but only half as much as in FIG Figure 1a shown.

Die in Figur 1a gezeigte relativ starke Schief-Stellung von Tisch 1 zum Fuß 8 hin wäre auf nachteilige Weise unverändert geblieben, falls wie herkömmlich Bierdeckel oder Keile oder ähnliche Gegenstände unter einem der Füße 4, 5 angebracht worden wären.In the Figure 1a The relatively strong inclined position shown from the table 1 to the foot 8 would have remained unchanged in a disadvantageous manner if, as conventionally, beer mats or wedges or similar objects had been attached under one of the feet 4, 5.

Der Ausgleich der Boden-Unebenheit B unter Fuß 9 durch die erfindungsgemäße Mechanik des Tischs 1 bewirkt also nicht nur, dass seine wackelige Aufstellung beendet ist, sondern auch, dass seine Tischplatte 15 um 50 % weniger schief geneigt ist als bei Verwendung der bisherigen Notbehelfe, z.B. Bierdeckel oder Keile.The compensation of the unevenness of the floor B under foot 9 by the mechanism according to the invention of the table 1 not only has the effect that its wobbly installation is ended, but also that its table top 15 is inclined 50% less obliquely than when using the previous makeshift aids, e.g. beer mats or wedges.

Solange Tisch 1 nach erfolgtem Ausgleich der Boden-Unebenheit B unter Fuß 9 nicht mehr hin und her wackelt, sondern nur in der beschriebenen Weise leicht schräg steht, ist diese geringe Neigung der Tischplatte 15 von Tisch 1 hinnehmbar, da sie kaum auffällt und meist lediglich unterhalb der Größenordnung des Gefälles, welches Trottoirs oder Terrassen als typische Stellflächen von Tisch 1 zwecks Regenwasser-Ablaufs ohnehin meist aufweisen und etwa 2 % beträgt, und welches eine entsprechende leichte Schräg-Stellung der Tischplatte 15 bewirkt, selbst wenn in diesen Fällen die Ebenen von Stellfläche des Tischs 1 und der Tischplatte 15 völlig parallel sind.As long as table 1 no longer wobbles back and forth after compensating for the unevenness in the floor B under foot 9, but only stands slightly inclined in the manner described, this slight inclination of table top 15 of table 1 is acceptable because it is hardly noticeable and mostly only below the order of magnitude of the slope, which sidewalks or terraces as typical parking areas of table 1 for the purpose of rainwater runoff usually have anyway and is about 2%, and which causes a corresponding slight inclination of the table top 15, even if in these cases the levels of Footprint of the table 1 and the table top 15 are completely parallel.

Keineswegs besteht erhöhte Gefahr, dass Gegenstände von der Tischplatte 15 rollen, sogar falls ein unachtsamer Nutzer kugelförmige oder zylindrische Gegenstände auf die Platte 15 legt. Selbst wenn kugelförmige oder zylindrische Gegenstände auf der Tischplatte 15 liegen würden, wäre durch die erfindungsgemäße Vorrichtung die Schrägstellung der Tischplatte 15 um 50 % gemindert gegenüber der herkömmlichen Bauweise und auf diese Weise würde ein Wegrollen kugelförmiger oder zylindrischer Gegenstände nur noch halb so heftig auftreten und nur noch halb so wahrscheinlich vorkommen wie bei herkömmlicher Bauweise.There is by no means an increased risk of objects rolling off the table top 15, even if an inattentive user places spherical or cylindrical objects on the table top 15. Even if spherical or cylindrical Objects would lie on the table top 15, the inclination of the table top 15 would be reduced by 50% compared to the conventional design by the device according to the invention and in this way a rolling away of spherical or cylindrical objects would only occur half as violently and only half as likely as with conventional construction.

Figur 2a zeigt Einzelheiten einer Klemmvorrichtung des Tischs 1. Zunächst zeigt Figur 2a in Vergrößerung den am Holm 10 befestigten Schaft 11 mit der oben daran angebrachten Führung 12, einen beiderseits daraus hervor ragenden Stift 16, ein Band 17 mit Bolzen 18 sowie in einer beispielhaften Ausführung einen manuell zu betätigenden Klemm-Hebel 19 mit Exzenter-Wulst 20 und ein zwischen dem Klemm-Hebel 19 und dem Bein 7 befindliches Zwischenstück 21, auf welchem der Exzenter-Wulst 20 gleiten kann und auf welches der Klemm-Hebel 19 Druck ausübt, wenn er nach unten umgelegt ist, um die Füße 8, 9 zu fixieren. Die Führung 12 und/oder das Zwischenstück 21 können Hohlkehlen aufweisen, die passend zu einem zylindrischen Querschnitt der Beine 6, 7 ausgebildet sein können. Bei einer anderen Querschnittsform der Beine 6, 7 kann eine entsprechend andere Form der Führung 12 und/oder des Zwischenstücks 21 vorgesehen sein, um die Beine 6, 7 möglichst gut in Eingriff zu nehmen. Der Stift 16 befestigt die Führung 12 am Band 17 so, dass sich diese gemeinsam in vertikaler Richtung bewegen können, jedoch eine beschränkte unabhängige Bewegung in horizontaler Richtung möglich ist. Hierzu ist im Band 17 beispielsweise mindestens ein Langloch, vorzugsweise zwei Langlöcher, zur Aufnahme des Stifts 16 vorgesehen. Figure 2a shows details of a clamping device of the table 1. First, FIG Figure 2a in an enlargement of the shaft 11 attached to the spar 10 with the guide 12 attached to the top, a pin 16 protruding therefrom on both sides, a band 17 with bolts 18 and, in an exemplary embodiment, a manually operated clamping lever 19 with an eccentric bead 20 and an intermediate piece 21 located between the clamping lever 19 and the leg 7, on which the eccentric bead 20 can slide and on which the clamping lever 19 exerts pressure when it is folded down to fix the feet 8, 9 . The guide 12 and / or the intermediate piece 21 can have fillets which can be designed to match a cylindrical cross section of the legs 6, 7. In the case of a different cross-sectional shape of the legs 6, 7, a correspondingly different shape of the guide 12 and / or the intermediate piece 21 can be provided in order to engage the legs 6, 7 as well as possible. The pin 16 attaches the guide 12 to the belt 17 so that they can move together in the vertical direction, but limited independent movement in the horizontal direction is possible. For this purpose, for example, at least one elongated hole, preferably two elongated holes, is provided in the band 17 for receiving the pin 16.

In der dargestellten Ausführungsform ist die erfindungsgemäße Vorrichtung, ein Boden-Unebenheiten B ausgleichender Tisch 1, mit Klemm-Hebel 19 und Exzenter-Wulst 20 ausgestaltet. Alternativ kann aber auch eine andere Art von Klemm-Mechanismus vorgesehen sein, beispielsweise ein manuell zu bedienender Dreh-Knauf, ein Klemm-Keil oder ein anderer Mechanismus, welcher geeignet ist, das Band 17 um die Beine 6 und 7 zu spannen.In the embodiment shown, the device according to the invention, a table 1 compensating for unevenness in the floor B, is designed with a clamping lever 19 and an eccentric bead 20. Alternatively, however, another type of clamping mechanism can also be provided, for example a manually operated rotary knob, a clamping wedge or another mechanism which is suitable for tensioning the band 17 around the legs 6 and 7.

Figur 2a zeigt die Klemmvorrichtung des Tischs 1 vor oder während des Ausgleichs der Boden-Unebenheit B unter Fuß 9:
Der Exzenter-Wulst 20 am Klemm-Hebel 19 ist so gedreht, dass er keinen Zug auf Bolzen 18 und Band 17 ausübt, so dass Band 17 lose um die Beine 6 und 7 liegt. Führung 12, Schaft 11, Holm 10 und die beweglichen Füße 8 und 9 können eine vertikale Ausgleichs-Bewegung aufwärts oder abwärts vornehmen, je nachdem, welche Art der Bewegung durch das Boden-Relief beim Aufstellen des Tischs 1 auf seinem Untergrund vorteilhaft ist. Figure 2a shows the clamping device of the table 1 before or during the leveling of the unevenness in the floor B under foot 9:
The eccentric bead 20 on the clamping lever 19 is rotated in such a way that it does not exert any tension on the bolt 18 and belt 17, so that the belt 17 lies loosely around the legs 6 and 7. Guide 12, shaft 11, spar 10 and the movable feet 8 and 9 can make a vertical compensation movement upwards or downwards, depending on which type of movement is advantageous through the floor relief when setting up the table 1 on its surface.

Figur 2b zeigt die Klemmvorrichtung nach Beendigung des Ausgleichs der Boden-Unebenheit B unter Fuß 9 im Zustand der Fixierung der Füße 8, 9. Im dargestellten Fall sind Füße 8, 9, Holm 10, Schaft 11 und Führung 12 an den Beinen 6, 7 aufwärts geglitten, um eine erhabene Boden-Unebenheit auszugleichen. Der Exzenter-Wulst 20 ist durch Abwärts-Bewegung des KlemmHebels 19 so gedreht, dass er am Bolzen 18 zieht und das Band 17 fest um die Beine 6, 7 spannt, so dass Führung 12, Schaft 11, Holm 10 und Füße 8, 9 sich vertikal nicht mehr bewegen können und Tisch 1 bei Gebrauch nicht mehr wackeln kann. Die Pfeile in Figur 2b links und rechts von Band 17 symbolisieren die Richtung, in welcher durch den Klemm-Hebel 19 Zug ausgeübt wird auf das Band 17. Figure 2b shows the clamping device after completion of the equalization of the unevenness of the ground B under foot 9 in the state of the feet 8, 9 being fixed. In the case shown, feet 8, 9, spar 10, shaft 11 and guide 12 have slid upwards on legs 6, 7 to level out any raised unevenness in the floor. The eccentric bead 20 is rotated by the downward movement of the clamping lever 19 so that it pulls on the bolt 18 and tightens the band 17 around the legs 6, 7, so that the guide 12, shaft 11, spar 10 and feet 8, 9 can no longer move vertically and table 1 can no longer wobble during use. The arrows in Figure 2b left and right of band 17 symbolize the direction in which tension is exerted on band 17 by clamping lever 19.

Alle Teile oder eine Anzahl der Teile des Untergestells von Tisch 1, das heißt alle Teile unterhalb der Tischplatte 15, können aus Metall, beispielsweise aus Stahl, hergestellt sein. Holm 10, Führung 12, Klemm-Hebel 19 und Zwischenstück 21, können auch aus Hartplastik gebildet sein.All parts or a number of the parts of the underframe of table 1, that is to say all parts below the table top 15, can be made of metal, for example steel. Spar 10, guide 12, clamping lever 19 and intermediate piece 21 can also be made of hard plastic.

Führung 12 und Zwischenstück 21 können horizontale Vertiefungen aufweisen, durch welche das Band 17 geführt wird, um diese drei Bauteile stets zusammenzuhalten.Guide 12 and intermediate piece 21 can have horizontal depressions through which the belt 17 is guided in order to always hold these three components together.

Figur 3 zeigt schematisch Details einer weiteren Ausgestaltung des Tischs 1. Figure 3 shows schematically details of a further embodiment of the table 1.

Zur seitlichen Stabilisierung des aus den Beinen 2, 3, 6, 7 und Füßen 4, 5, 8, 9 gebildeten Untergestells des Tischs, um Hin- und Her-Schwingen der Tischplatte 15, beispielsweise in Längsrichtung der Klemmvorrichtung zu verhindern, kann eine Aussteifung des Untergestells vorgesehen sein. Diese kann so beschaffen sein, dass an den beiden beweglichen Füßen 8, 9 jeweils eine senkrecht nach oben gerichtete Rohr-Halbschale 22 angeordnet ist, beispielsweise jeweils starr angebracht durch Schweißen. Beide Rohr-Halbschalen 22 liegen beispielsweise außen, das heißt auf voneinander abgewandten Seiten der starren Beine 6, 7, an den starren Beinen 6, 7 des Untergestells an. In einer anderen Ausführungsform können die Rohr-Halbschalen 22 an einer anderen Stelle, beispielsweise innen an den starren Beinen 6, 7 anliegen.To laterally stabilize the base of the table, which is formed from legs 2, 3, 6, 7 and feet 4, 5, 8, 9, in order to prevent the table top 15 from swinging back and forth, for example in the longitudinal direction of the clamping device, a stiffener can be used the underframe be provided. This can be designed in such a way that a tube half-shell 22 directed vertically upwards is arranged on each of the two movable feet 8, 9, for example each rigidly attached by welding. Both pipe half-shells 22 are, for example, on the outside, that is to say on sides of the rigid legs 6, 7 facing away from one another, on the rigid legs 6, 7 of the underframe. In another embodiment, the pipe half-shells 22 can rest at another point, for example on the inside of the rigid legs 6, 7.

Ein Innendurchmesser der Rohr-Halbschalen 22 kann geringfügig größer gewählt sein als ein Außendurchmesser der starren Beine 6, 7.An inner diameter of the pipe half-shells 22 can be selected to be slightly larger than an outer diameter of the rigid legs 6, 7.

Aufgabe dieser Rohr-Halbschalen 22 ist, seitlich pendelnde Schwing-Bewegungen des Untergestells an dessen oberem Teil zu unterdrücken.The task of these pipe half-shells 22 is to suppress sideways oscillating oscillating movements of the underframe on its upper part.

Damit die Rohr-Halbschalen 22 nicht an den Beinen 6, 7, welche an ihren Innenseiten liegen, scheuern, können sie dünne Halbschalen aus gleitfähigem Kunststoff auf der Innenseite tragen oder mit einer Beschichtung, beispielsweise aus gleitfähigem Kunststoff, versehen sein.So that the pipe half-shells 22 do not rub against the legs 6, 7, which are on their insides, they can carry thin half-shells made of slidable plastic on the inside or be provided with a coating, for example made of slidable plastic.

Damit die Rohr-Halbschalen 22 sich starr verhalten und so den Tisch stabilisieren sobald der Tisch 1 durch den Klemmhebel 19 verriegelt wird, können die oberen Enden der Rohr-Halbschalen in die Klemmvorrichtung einbezogen sein, derart, dass sie von unten in die Klemmvorrichtung hineinragen und durch diese an den starren Beinen 6, 7 auf der Innenseite der Rohr-Halbschalen 22 festgeklemmt werden.So that the pipe half-shells 22 behave rigidly and thus stabilize the table as soon as the table 1 is locked by the clamping lever 19, the upper ends of the pipe half-shells can be included in the clamping device in such a way that they protrude into the clamping device from below and are clamped by these on the rigid legs 6, 7 on the inside of the pipe half-shells 22.

Anstelle der Rohr-Halbschalen 22 kann auch je ein längliches Bauteil mit einem anderen Profil verwendet werden, die an den starren beinen 6, 7 anliegt und beispielsweise in die Klemmvorrichtung hinein geführt ist.Instead of the pipe half-shells 22, it is also possible to use an elongated component with a different profile, which rests against the rigid legs 6, 7 and is guided into the clamping device, for example.
