One of these parts forms an inner wall (8) with a row (9) of adjustment holes while the other part has an adjacent outer wall (7) with at least one fixing hole (10). In order to hold the top part (6) in its position of height, there is a fixing device with at least one insertion member (11) which can be inserted through the assigned fixing hole (10) and the relevant adjustment hole (9). The fixing device forms a contact surface (12) which comes to rest on the outside of the outer wall (7), and the insertion member (11) comprises a hooking projection (15), projecting in the longitudinal direction of the leg, with a sloping surface (14) facing the contact surface (12). In the position of use, in which the insertion member (11) is seated on the bottom part (5) and the top part (6) is seated on the insertion member (11), the hooking projection (15) grips behind the edge region of the adjustment hole (9) and, with its sloping surface (14), holds the inner wall (8) against the outer wall (7) supported on the contact surface (12). <IMAGE>

Description

Die Erfindung betrifft ein höhenverstellbares Standbein länglicher Gestalt für Möbelstücke od.dgl., mit einem Unterteil und einem Oberteil, von denen eines eine innere Wand mit einer in Beinlängsrichtung angeordneten Reihe von Verstellöchern und das andere eine der inneren Wand benachbarteäußere Wand mit mindestens einem Feststelloch aufweist, und mit einer das Oberteil in seiner jeweiligen Höhenlage am Unterteil haltenden Feststelleinrichtung die mindestens ein Steckglied enthält, das durch das zugeordnete Feststellloch und das in der jeweiligen Höhenlage mit diesem korrespondierende Verstelloch steckbar ist. Ein Standbein dieser Art ist beispielweise durch die FR-A-2 590 780 bekannt geworden.The invention relates to a height-adjustable leg of elongated shape for furniture or the like. With a lower part and an upper part, one of which has an inner wall with a row of adjustment holes arranged in the longitudinal direction of the leg and the other has an outer wall adjacent to the inner wall with at least one locking hole , and with a locking device holding the upper part in its respective height position on the lower part, which contains at least one plug-in element which can be inserted through the assigned fixing hole and which in the respective height position corresponds to this adjustment hole. A mainstay of this type has become known, for example, from FR-A-2 590 780.

Damit Tische, insbesondere Schreib- oder Arbeitstische für Kinder und Jugendliche, an die jeweils gewünschte Höhe bzw. an die Größe der jeweiligen Person angepaßt werden können, können sie höhenverstellbare Standbeine aufweisen. Solche Standbeine sind auch für andere Möbelstücke, beispielsweise für Regale usw. denkbar.So that tables, in particular desks or work tables for children and adolescents, can be adapted to the desired height or the size of the respective person, they can have height-adjustable legs. Such pillars are also conceivable for other pieces of furniture, for example for shelves, etc.

Aufgabe der vorliegenden Erfindung ist es, ein höhenverstellbares Standbein der eingangs genannten Art zu schaffen, bei dem die Höhenverstellung einfach in der Handhabung ist und die Feststelleinrichtung bei einfachem Aufbau einen stabilen Halt ergibt.The object of the present invention is to provide a height-adjustable pillar of the type mentioned, in which the height adjustment is easy to use and the locking device provides a stable hold with a simple structure.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Feststelleinrichtung eine an der der inneren Wand entgegengesetzten Außenseite der äußeren Wand zur Anlage gelangende Anlagefläche bildet und das Steckglied einen in Beinlängsrichtung vorstehenden, mit Abstand zur Anlagefläche angeordneten und an seiner der Anlagefläche zugewandten Seite eine Schrägfläche bildenden Hintergreifvorsprung aufweist, der in der Gebrauchslage, wenn unter dem Gewicht des Oberteils das Steckglied auf dem Unterteil und das Oberteil auf dem Steckglied aufsitzt, den Lochrandbereich des Verstelloches hintergreift und mit seiner Schrägfläche die innere Wand gegen die an der Anlagefläche abgestützte äußere Wand hält.This object is achieved in that the locking device forms a contact surface on the outside of the outer wall opposite the inner wall and the plug-in member projects in the longitudinal direction of the leg, arranged at a distance from the contact surface and on its side facing the contact surface forming an inclined gripping projection has in the position of use, when under the weight of the upper part the plug-in member sits on the lower part and the upper part on the plug-in member, engages behind the hole edge region of the adjustment hole and holds the inner wall with its inclined surface against the outer wall supported on the contact surface.

Das Steckglied wird bei leicht angehobenem Oberteil durch das Feststelloch und das betreffende Verstelloch gesteckt, wonach das Oberteil abgesenkt wird. Hierdurch verringert sich der lichte Querschnitt des von dem Feststelloch und dem Verstelloch gebildeten Durchtritts, so daß die Schrägfläche wirksam wird, die die Gewichtskraft des Oberteils in eine Querkraft umsetzt, durch die die beiden Wände zwischen dem Hintergreifvorsprung und der Anlagefläche fest miteinander verspannt werden. Auf diese Weise wird nicht nur die Höhenlage des Oberteils sicher fixiert sondern gleichzeitig die Möglichkeit eines Wackelns des Oberteils verhindert, so daß sich ein sehr stabiler Zusammenhalt ergibt. Dabei hält das Steckglied ohne irgend ein Zusatzteil sicher an Ort und Stelle und kann nicht unabsichtlich aus dem Verstelloch herausgezogen werden.With a slightly raised upper part, the plug-in element is inserted through the fixing hole and the relevant adjusting hole, after which the upper part is lowered. This reduces the clear cross-section of the passage formed by the locking hole and the adjusting hole, so that the inclined surface is effective, which converts the weight of the upper part into a transverse force, by means of which the two walls are firmly clamped to one another between the engagement grip projection and the contact surface. That way not only securely fixes the height of the upper part but at the same time prevents the possibility of the upper part wobbling, so that there is very stable cohesion. The connector holds securely in place without any additional part and cannot be accidentally pulled out of the adjustment hole.

Will man eine Höhenverstellung vornehmen, muß man nur das Oberteil leicht anheben, so daß sich der lichte Querschnitt des von dem Feststelloch und dem Verstelloch gebildeten Durchtritts wieder auf ein Maß vergrößert, das das Herausziehen des Steckgliedes ermöglicht.If you want to make a height adjustment, you only have to lift the upper part slightly, so that the clear cross section of the passage formed by the fixing hole and the adjusting hole increases again to a level that enables the plug-in member to be pulled out.

Es ist ersichtlich, daß auch eine einfache Handhabung vorliegt. Ferner ist zum Erreichen des gewünschten Ziels nur die genannte Formgebung des Steckgliedes erforderlich, so daß auch die Gestehungskosten niedrig sind.It can be seen that there is also simple handling. Furthermore, only the aforementioned shape of the plug-in member is required to achieve the desired goal, so that the production costs are also low.

Der aus den Fig. 1 und 2 hervorgehende Tisch 1 weist eine Tischplatte 2 auf, die von zwei jeweils an einem seitlichen Tischende angeordneten, gleich ausgebildeten Standbeinen 3 gehalten wird. An jedem Standbein 3 ist unten noch ein Horizontalfuß 4 befestigt, so daß sich ein standsicherer Tisch ergibt, obwohl nur zwei Standbeine vorhanden sind.The table 1 shown in FIGS. 1 and 2 has a table top 2 which is held by two legs 3 of the same design which are each arranged on a side end of the table. On each leg 3 a horizontal foot 4 is attached below, so that there is a stable table, although there are only two legs.

Die Standbeine 3 sind höhenverstellbar, so daß die Tischplatte 2 in die gewünschte Höhe gebracht werden kann. Wegen der gleichen Ausbildung wird im folgenden nur eines der Standbeine beschrieben. Dabei wird zunächst noch darauf hingewiesen, daß sich die Anzahl der Standbeine nach dem jeweiligen Möbelstück richtet, das nicht unbedingt ein Tisch sein muß sondern auch beispielsweise ein Regal sein kann.The legs 3 are adjustable in height so that the table top 2 can be brought to the desired height. Because of the same training, only one of the mainstays is below described. It is initially pointed out that the number of legs depends on the respective piece of furniture, which does not necessarily have to be a table but can also be a shelf, for example.

Das längliche Standbein 3 weist ein dem Boden zugewandtes Unterteil 5 und ein Oberteil 6 auf, die sich überlappen und mit unterschiedlich großer Überlappungslänge aneinander festgelegt werden können. Eines der beiden Teile, im dargestellten Falle das Oberteil 6, bildet eine äußere, bei der Handhabung der Feststelleinrichtung dem Benutzer zugewandte Wand 7, während das andere Teil, beim Ausführungsbeispiel das Unterteil 5, eine der äußeren Wand 7 benachbarte und parallel zu ihr verlaufende innere Wand 8 bildet. Dabei handelt es sich im dargestellten Falle sowohl beim Unterteil 5 als auch beim Oberteil 6 um ein Rohr mit rechteckigem Querschnitt, wobei Metall als Herstellungsmaterial vorgesehen ist. Die beiden das Unterteil und das Oberteil bildenden Rohre sind teleskopartig ineinandergesteckt und dabei aufgrund ihres rechteckigen Querschnitts unverdrehbar aneinander geführt.The elongated pillar 3 has a lower part 5 facing the floor and an upper part 6 which overlap and can be fixed to one another with different lengths of overlap. One of the two parts, in the case shown the upper part 6, forms an outer wall 7 facing the user when handling the locking device, while the other part, in the exemplary embodiment the lower part 5, is an inner wall adjacent to the outer wall 7 and parallel to it Wall 8 forms. In the case shown, both the lower part 5 and the upper part 6 are a tube with a rectangular cross section, metal being provided as the production material. The two tubes forming the lower part and the upper part are telescopically inserted into one another and, due to their rectangular cross-section, are non-rotatably guided together.

Wie erwähnt, bildet im dargestellten Falle das Oberteil 6 die äußere Wand 7 und das Unterteil 5 die an der äußeren Wand 7 dem Benutzer der Feststelleinrichtung abgewandte innere Wand 8. Dies könnte jedoch auch umgekehrt sein, d.h. das Oberteil könnte die innere Wand und das Unterteil die äußere Wand bilden. Diese Variante ist nicht gesondert dargestellt. Die bei dieser Variante vorliegenden Verhältnisse ergeben sich durch einfaches Umdrehen der Figuren. Ferner wird bereits an dieser Stelle darauf hingewiesen, daß bei dieser umgekehrten Anordnung die gleiche Feststelleinrichtung verwendet werden kann, was wiederum durch einfaches Umdrehen vor allem der Fig. 3, 4,11 und 12 ohne weiteres ersichtlich wird.As mentioned, in the illustrated case the upper part 6 forms the outer wall 7 and the lower part 5 forms the inner wall 8 facing away from the user of the locking device on the outer wall 7. However, this could also be reversed, ie the upper part could be the inner wall and the lower part form the outer wall. This variant is not shown separately. The conditions in this variant result from simply turning the figures over. Furthermore, it is already pointed out at this point that the same locking device can be used in this reverse arrangement, which in turn is readily apparent by simply turning around, in particular FIGS. 3, 4, 11 and 12.

Die innere Wand 8 weist eine in Beinlängsrichtung angeordnete Reihe von Verstellöchern 9 und die äußere Wand 7 mindestens ein Feststelloch 10 auf. Beim Ausführungsbeispiel sind drei solche Feststellöcher 10 vorhanden, die im Rasterabstand oder einem mehrfachen hiervon der Verstellochreihe 9 angeordnet sind. Das Oberteil 6 wird in seiner jeweiligen Höhenlage am Unterteil 5 mittels einer Feststelleinrichtung gehalten, die mindestens ein Steckglied 11 enthält, das durch das zugeordnete Feststelloch 10 und das in der jeweiligen Höhenlage mit diesem korrespondierende Verstelloch 9 steckbar ist. Dabei entspricht die Anzahl der Steckglieder 11 der Anzahl der Feststellöcher 10. Diese Anzahl richtet sich nach den Stabilitätserfordernissen, d.h. nach dem Gewicht, das von dem bzw. den Steckgliedern von oben her aufgenommen wird.The inner wall 8 has a row of adjustment holes 9 arranged in the longitudinal direction of the leg and the outer wall 7 has at least one locking hole 10. In the exemplary embodiment there are three such fixing holes 10 which are arranged at a grid spacing or a multiple thereof of the adjusting hole row 9. The upper part 6 is held in its respective height on the lower part 5 by means of a locking device which contains at least one plug-in element 11 which can be inserted through the associated locking hole 10 and which in the respective height position corresponds to the adjusting hole 9. The number of plug-in links 11 corresponds to the number of locking holes 10. This number depends on the stability requirements, i.e. according to the weight that is taken up by the connector (s) from above.

Die Feststellöcher 10 besitzen gleiche Gestalt wie die Verstellöcher 9, so daß man, ist das mindestens eine Steckglied 11 noch nicht eingesteckt, durch Anheben des Oberteils 6 das betreffende Feststelloch 10 in eine fluchtende Lage zum die Höhenstellung des Oberteils bestimmenden Verstellloch 9 bringen kann, in der sich das Feststelloch und das Verstelloch überdecken (Fig. 3). Steckt man das mindestens eine Steckglied 11 ein, kann man das Oberteil 6 loslassen, wonach es auf dem mindestens einen Steckglied 11 aufsitzt, das seinerseits auf dem Unterteil 5 aufliegt, so daß die Höhenlage des Oberteils 6 fixiert ist (Fig. 4).The locking holes 10 have the same shape as the adjustment holes 9, so that, if the at least one plug-in member 11 has not yet been inserted, the locking hole 10 in question can be brought into an aligned position by lifting the upper part 6 into the adjustment hole 9 determining the height of the upper part which overlap the locking hole and the adjustment hole (Fig. 3). If you insert the at least one plug-in member 11, you can let go of the upper part 6, after which it sits on the at least one plug-in member 11, which in turn rests on the lower part 5, so that the height of the upper part 6 is fixed (FIG. 4).

Die Feststelleinrichtung bildet eine an der der inneren Wand 8 entgegengesetzten Außenseite der äußeren Wand 7 zur Anlage gelangende Anlagefläche 12. Zweckmäßigerweise wird diese Anlagefläche 12 von einer Anlageplatte 13 od.dgl. gebildet, die sich in Beinlängsrichtung erstreckt und von der das mindestens eine Steckglied 11 absteht, das zapfen- oder hackenähnliche Gestalt besitzt und zweckmäßigerweise einstückig an die Anlageplatte 13 od.dgl. angeformt ist, falls es sich um ein Kunststoffteil handelt. Ferner weisen die Steckglieder 11 jeweils einen in Beinlängsrichtung vorstehenden, mit Abstand zur Anlagefläche 12 angeordneten und an seiner der Anlagefläche 12 zugewandten Seite eine Schrägfläche 14 bildenden Hintergreifvorsprung 15 auf, der in der aus den Fig. 4,10 und 12 hervorgehenden Gebrauchslage, wenn, wie schon erwähnt, unter dem Gewicht des Oberteils 6 das Steckglied 11 auf dem Unterteil 5 und das Oberteil 6 auf dem Steckglied 11 aufsitzt, den Lochrandbereich des betreffenden Verstelloches 9 hintergreift und mit seiner Schrägfläche 14 die innere Wand 8 gegen die an der Anlagefläche 12 abgestützte äußere Wand 7 hält.The locking device forms a contact surface 12 on the outside of the outer wall 7 opposite the inner wall 8. This contact surface 12 is expediently covered by a contact plate 13 or the like. formed, which extends in the longitudinal direction of the leg and from which the at least one plug-in member 11 protrudes, has the shape of a peg or hook, and expediently integrally or similarly on the contact plate 13. is molded, if it is a plastic part. Furthermore, the plug-in members 11 each have a rear engagement projection 15 which projects in the longitudinal direction of the leg, is arranged at a distance from the contact surface 12 and forms an inclined surface 14 on its side facing the contact surface 12, which in the position of use shown in FIGS. 4, 10 and 12 when As already mentioned, the plug member 11 sits on the lower part 5 and the upper part 6 on the plug member 11 under the weight of the upper part 6, engages behind the hole edge region of the adjustment hole 9 in question and with its inclined surface 14 supports the inner wall 8 against the one supported on the contact surface 12 outer wall 7 holds.

Somit ergibt sich ausgehend von der Stellung nach Fig. 3 folgende Wirkungsweise:
Bei weggenommener Feststelleinrichtung wird das Oberteil 6 von Hand angehoben, bis die Feststellöcher 10 jeweils mit einem Verstelloch 9 fluchten. Jedes Feststelloch 10 bildet dann mit dem zugewandten Verstelloch 9 einen Durchtritt mit größtmöglichem Querschnitt, so daß das betreffende Steckglied 11 hindurchpaßt. Sodann werden die an der Anlageplatte 13 od.dgl. sitzenden Steckglieder 11 durch die Lochpaare 9,10 gesteckt. Hierbei gelangt der Hintergreifvorsprung 15 jedes Steckgliedes 11 hinter die der äußeren Wand 7 entgegengesetzte Innenseite der inneren Wand 8. Anschließend senkt man das Oberteil 6 ab, so daß sich die lichte Höhe des von dem jeweiligen Feststelloch 10 mit dem zugehörigen Verstelloch 9 gebildeten Durchtritts verkleinert, so daß das betreffende Steckglied 11 in Höhenrichtung gesehen zwischen den entgegengesetzten Lochrandbereichen des Feststelloches und des Verstelloches eingeklemmt wird. Hierbei verlagert sich der Hintergreifvorsprung 15 in Höhenrichtung relativ zum zugewandten Lochrandbereich des Verstelloches 9, so daß dieser von der Schrägfläche 14 hintergriffen wird. Das Gewicht des Oberteils 6 drückt die Schrägfläche 14 fest gegen die innenseitige Kante des Verstelloch-Wandbereichs, so daß dieser und somit die innere Wand 8 nach außen gegen die äußere Wand 7 und diese gegen die Anlagefläche 12 gedrückt wird. über die Schrägfläche 14 wird also die Gewichtskraft in eine Querkraft umgesetzt, durch die die Anlagefläche 12, die beiden Wände 7,8 und die Schrägfläche 14 fest miteinander verspannt werden.
Based on the position according to FIG. 3, this results in the following mode of operation:
When the locking device is removed, the upper part 6 raised by hand until the locking holes 10 are each aligned with an adjusting hole 9. Each locking hole 10 then forms with the facing adjustment hole 9 a passage with the largest possible cross section, so that the relevant plug member 11 fits through. Then the or the like on the contact plate 13. seated plug-in members 11 inserted through the pairs of holes 9,10. In this case, the rear grip projection 15 of each plug-in member 11 comes behind the inside of the inner wall 8 opposite the outer wall 7. Then the upper part 6 is lowered so that the clear height of the passage formed by the respective fixing hole 10 with the associated adjusting hole 9 is reduced, so that the relevant plug member 11 is seen in the vertical direction between the opposite hole edge regions of the locking hole and the adjustment hole. Here, the rear gripping projection 15 is displaced in the height direction relative to the hole edge region of the adjustment hole 9, so that the inclined surface 14 engages behind it. The weight of the upper part 6 presses the inclined surface 14 firmly against the inside edge of the adjustment hole wall area, so that it and thus the inner wall 8 are pressed outwards against the outer wall 7 and this against the contact surface 12. Via the inclined surface 14, the weight force is converted into a transverse force, by means of which the contact surface 12, the two walls 7, 8 and the inclined surface 14 are firmly clamped together.

Im dargestellten Falle wird, wie schon erwähnt, die innere Wand 8 vom Unterteil 5 gebildet. Hierbei steht der Hintergreifvorsprung 14 nach unten hin vom Steckglied 11 vor, so daß er den unteren Randbereich des betreffenden Verstellloches 9 hintergreift.In the case shown, as already mentioned, the inner wall 8 is formed by the lower part 5. Here, the rear gripping projection 14 projects downward from the plug-in member 11, so that it engages behind the lower edge region of the adjustment hole 9 concerned.

Wird die innere Wand dagegen vom Oberteil gebildet, steht der Hintergreifvorsprung nach oben hin vor und hintergreift dann mit seiner Schrägfläche den oberen Randbereich des jeweiligen Verstelloches.If, on the other hand, the inner wall is formed by the upper part, the rear gripping projection protrudes upwards and then engages behind with its inclined surface the upper edge area of the respective adjustment hole.

Will man die Höhenlage des Oberteils 6 verändern, hebt man dieses an, bis der von den Lochpaaren 9,10 gebildete Durchtrittsquerschnitt das Herausziehen des betreffenden Steckgliedes 11 gestattet.If you want to change the height of the upper part 6, you raise it until the passage cross-section formed by the pairs of holes 9, 10 allows the relevant plug-in member 11 to be pulled out.

Aus Fig. 12 die eine ansonsten gleiche Anordnung zeigt, geht eine variierte Steckgliedgestalt hervor, indem das Steckglied 11a einen dem Hintergreifvorsprung 15 in vertikaler Richtung entgegengesetzten Hintergreifabsatz 16 aufweist, der in der Gebrauchslage innerhalb des Verstelloches 9 angeordnet ist und am Lochrandbereich des Feststelloches 10 anliegt. Dieser Hintergreifabsatz 16 ist an sich für den festen Zusammenhalt der verschiedenen Einzelteile nicht erforderlich, er stabilisiert jedoch das Steckglied 11a zusätzlich an der äußeren Wand 7. über ihn wird das Steckglied 11a an der dem Hintergreifvorsprung 15 entgegengesetzten Seite abgestützt, was einem evtl. leichten Verbiegen des Steckgliedes 11a durch die über die Schrägfläche 14 ausgeübten Kraft entgegenwirkt. Der Hintergreifabsatz 16 kann eine am Lochrandbereich des Feststelloches 10 angreifende und die äußere Wand 7 gegen die Anlagefläche 12 haltende Schrägfläche 17 bilden.12, which shows an otherwise identical arrangement, shows a varied plug-in shape in that the plug-in member 11a has a rear-engaging shoulder 16 which is opposite the rear-engaging projection 15 in the vertical direction and which, in the position of use, is arranged within the adjustment hole 9 and bears against the hole edge region of the locking hole 10 . This rear gripping heel 16 is not required per se for the solid cohesion of the various individual parts, but it additionally stabilizes the plug-in member 11a on the outer wall 7. The plug-in member 11a is supported on it on the side opposite the rear gripping projection 15, which may result in slight bending counteracts the plug member 11a by the force exerted on the inclined surface 14. The rear gripping shoulder 16 can form an inclined surface 17 engaging the hole edge region of the fixing hole 10 and holding the outer wall 7 against the contact surface 12.

Die Verstellöcher 9 und das mindestens eine Feststelloch 10 sind zweckmäßigerweise Langlöcher mit abgerundeten Lochenden, wie vor allem aus Fig. 5 hervorgeht. Das mindestens eine Steckglied 11; 11a besitzt eine im wesentlichen der Lochbreite entsprechende Breite, wobei mindestens die auf der inneren Wand 8 aufsitzende Steckgliedpartie sowie die Steckgliedpartie, auf der die äußere Wand 7 aufsitzt, den Langlochenden entsprechend abgerundet sind. In einem solchen Falle erhält man eine großflächige und daher stabile Kraftaufnahme.The adjustment holes 9 and the at least one locking hole 10 are expediently elongated holes with rounded hole ends, as can be seen above all from FIG. 5. The at least one connector 11; 11a has a width essentially corresponding to the hole width, at least the plug-in part sitting on the inner wall 8 and the plug-in part on which the outer wall 7 is seated being rounded off in accordance with the elongated hole ends. In such a case, a large and therefore stable force absorption is obtained.

Um das Einstecken der Steckglieder 11; 11a in die Feststelllöcher 10 zu erleichtern, kann der der Anlagefläche 12 abgewandte Endbereich der Steckglieder eine sich zum Ende hin verjüngende Gestalt aufweisen. Diese sich verjüngende Gestalt läßt sich durch eine umlaufende, im wesentliche konusförmige Umfangsfläche 18 erhalten.In order to insert the plug-in members 11; 11a into the fixing holes 10, the end region of the plug-in members facing away from the contact surface 12 can have a shape that tapers towards the end. This tapered shape can be obtained by a circumferential, essentially conical peripheral surface 18.

Wie erläutert, wird das Gewicht des Oberteils 6 ausgenutzt, um das jeweilige Steckglied 11; 11a in der Gebrauchslage zu halten. Im Falle eines Anhebens des ganzen Möbelstücks, beispielsweise wenn man den Tisch 1 verstellen möchte und ihn hierzu an der Tischplatte 2 hochhebt, verlagert sich das Oberteil 6 jedoch relativ zum Unterteil 5 so weit nach oben, daß das jeweilige Feststelloch 10 und das benachbarte Verstelloch 9 in eine solche Relativlage zueinander gelangen, daß das Steckglied 11; 11a durch beide hindurchpaßt, so daß die Feststelleinrichtung unabsichtlich vom Standbein wegfallen kann.As explained, the weight of the upper part 6 is used to the respective connector 11; 11a to keep in the position of use. In the event that the entire piece of furniture is lifted, for example if you want to adjust the table 1 and lift it up on the table top 2, the upper part 6 is displaced relative to the lower part 5 so far that the respective fixing hole 10 and the adjacent adjusting hole 9 get into such a relative position to one another that the plug-in member 11; 11a fits through both, so that the locking device can accidentally fall off the mainstay.

Um dies zu verhindern, kann die äußere Wand 7 ein in Gebrauchslage mit einem Verstelloch 9 korrespondierendes Sicherungsloch 19; 19a aufweisen, wobei ein Sicherungsstück 20; 20a vorhanden ist, das zwischen einer durch das Sicherungsloch 19; 19a in das Verstelloch 9 eingreifenden wirksamen Stellung und einer aus dem Verstelloch 9 entfernten unwirksamen Stellung bewegbar ist.To prevent this, the outer wall 7 can be an in Use position with an adjustment hole 9 corresponding securing hole 19; 19a, wherein a securing piece 20; 20a is present, which between one through the securing hole 19; 19a can be moved into the active position engaging the adjustment hole 9 and an inactive position removed from the adjustment hole 9.

Das betreffende Sicherungsstück 20; 20a greift also in seiner wirksamen Stellung durch das Sicherungsloch 19; 19a hindurch in das benachbarte Verstelloch 9, wobei die Anordnung so getroffen ist, daß das Sicherungsstück 20; 20a einem Anheben des Oberteils 6 entgegensteht.The relevant securing piece 20; 20a thus engages in its effective position through the securing hole 19; 19a into the adjacent adjustment hole 9, the arrangement being such that the securing piece 20; 20a prevents the upper part 6 from being raised.

Im Falle des Ausführungsbeispiels nach den Fig. 3,4,9 und 10 durchgreift das Sicherungsstück 20 die Anlageplatte 13 od.dgl. Dabei enthält die Anlageplatte 13 od.dgl. eine schlüssellochartige Durchbrechung 21. Ferner weist das Sicherungsstück 20 ein hakenartiges Ende 22 auf, das radial von einer zylindrischen Sicherungsstückpartie 23 absteht, die in einen dem Hakenende 22 zugewandten Bereich 24 kleineren Durchmessers und in einen dem Hakenende 22 abgewandten Bereich 25 größeren Durchmessers unterteilt ist. Dieses Sicherungsstück 20 ist durch die Durchbrechung 21 der Anlageplatte 13 od.dgl. steckbar. Hierbei gelangt die Partie 23 durch die zylindrische Erweiterung 26 der schlüssellochförmigen Durchbrechung 21, während das Hakenende 22 durch den Langlochbereich 27 der Durchbrechung 21 hindurchtritt. Die zylindrische Erweiterung 26 der Durchbrechung 21 ist gestuft, und zwar derart, daß außen ein Bereich 28 größeren Durchmessers und innen ein Bereich 29 kleineren Durchmessers vorhanden ist.In the case of the exemplary embodiment according to FIGS. 3, 4, 9 and 10, the securing piece 20 extends through the contact plate 13 or the like. The contact plate 13 or the like. a keyhole-like opening 21. Furthermore, the securing piece 20 has a hook-like end 22 which projects radially from a cylindrical securing piece section 23 which is divided into an area 24 of smaller diameter facing the hook end 22 and an area 25 of larger diameter facing away from the hook end 22. This locking piece 20 is through the opening 21 of the contact plate 13 or the like. pluggable. The part 23 passes through the cylindrical extension 26 of the keyhole-shaped opening 21, while the hook end 22 passes through the elongated hole region 27 of the opening 21. The cylindrical extension 26 of the opening 21 is stepped in such a way that there is an area 28 of larger diameter on the outside and an area 29 of smaller diameter on the inside.

Der Bereich 28 nimmt den Bereich 25 und der Bereich 29 den Bereich 24 der Sicherungsstückpartie 23 auf. Hierbei stößt der zwischen den beiden Bereichen 24 und 25 vorhandene Ringabsatz 30 der Sicherungsstückpartie 23 gegen die Stufenfläche 31 der Durchbrechung 21. Im eingesteckten Zustand - das Einstecken erfolgt erst, wenn das Oberteil 6 abgelassen ist und die Steckglieder 11 sich in ihrer Verriegelungsstellung befinden - greift das Sicherungsstück 20 also durch das Sicherungsloch 19 und das zugewandte Verstelloch 9, so daß es seine wirksame Stellung einnimmt, in der es zwischen einer durch die Durchbrechung 21 und die beiden Löcher 19,9 passenden Löseposition (entspricht der in Fig. 4 mit ausgezogenen Linien gezeichneten Drehlage) und einer Verriegelungsposition (in Fig. 4 gestrichelt angedeutet) verdrehbar ist, in der das Hakenende 22 die innere Wand 8 hintergreift. Beim Verdrehen ist das Sicherungsstück 20 in der zylindrischen Erweiterung 26 der Durchbrechung 21 gelagert.The area 28 receives the area 25 and the area 29 the area 24 of the securing piece section 23. Here, the ring shoulder 30 of the securing piece section 23 present between the two areas 24 and 25 abuts against the step surface 31 of the opening 21. In the inserted state - the insertion takes place only when the upper part 6 is drained and the plug-in members 11 are in their locking position the securing piece 20 thus through the securing hole 19 and the facing adjustment hole 9, so that it assumes its effective position in which it is between a release position fitting through the opening 21 and the two holes 19.9 (corresponds to that in FIG. 4 with solid lines drawn rotational position) and a locking position (indicated by dashed lines in Fig. 4) in which the hook end 22 engages behind the inner wall 8. When rotating the locking piece 20 is mounted in the cylindrical extension 26 of the opening 21.

Damit das Hakenende 22 in seiner Verriegelungsposition festhält, kann seine die Innenseite der inneren Wand 8 hintergreifende Verriegelungsfläche 32 abgerundet sein, so daß sie beim Verdrehen des Sicherungsstücks gut über die Randkante des Verstelloches 9 laufen kann und anschließend durch Selbsthemmung festhält. Nach innen hin kann das Hakenende 22 nicht ausweichen, da das Sicherungsstück im dargestellten Falle über der Ringabsatz 30 an der Stufenfläche 31 anliegt.So that the hook end 22 holds in its locking position, its locking surface 32 engaging behind the inside of the inner wall 8 can be rounded, so that it can run well over the edge of the adjustment hole 9 when the locking piece is turned and then holds by self-locking. The hook end 22 cannot deflect towards the inside, since in the illustrated case the securing piece rests on the step surface 31 via the ring shoulder 30.

An die Außenseite des Sicherungsstücks 20 ist ein Drehgriff 33 angesetzt, der beim Ausführungsbeispiel tellerähnliche Form aufweist.On the outside of the securing piece 20, a turning handle 33 is attached, which in the exemplary embodiment is plate-like Has shape.

Die Drehlage der Löseposition und der Verriegelungsposition des Sicherungsstücks 20 kann durch einen Anschlag vorgegeben sein. Hierzu kann von der Aussenseite der Anlageplatte 13 od.dgl. ein Anschlagstift 34 vorstehen, gegen den der Drehgriff 33 sowohl in der Lösepositon als auch in der Verriegelungsposition läuft. Der Drehgriff 33 kann dosenförmige Gestalt mit zum Anschlagkörper 34 hin offener Dosenseite aufweisen, wobei im Drehgriff 33 Radialstege 35 bis 39 (die weiteren Radialstege wurden der Übersichtlichkeit wegen nicht mit einer Bezugsziffer belegt) verlaufen können, von denen die Radialstege 35 und 39, die etwa um 180o gegeneinander versetzt sind, jeweils einen Anschlag für den Anschlagstift in der Löseposition bzw. in der Verriegelungsposition bilden. In Fig. 9 ist links unten beim Radialsteg 35 strichpunktiert der Anschlagstift dargestellt, wobei sich der Drehgriff und somit das Sicherungsstück 20 in der Löseposition befindet, in der es herausgezogen oder eingesteckt werden kann. Dreht man den Drehgriff 33 in Richtung gemäß Pfeil 40, überfährt der Drehgriff 30 den Anschlagstift 34, bis sein Radialsteg 39 am Anschlagstift zur Anlage gelangt. Die dazwischen liegenden Radialstege 36,37,38 weisen jeweils eine Aussparung 41 für den Durchtritt des Anschlagstifts beim Verdrehen des Drehgriffs auf.The rotational position of the release position and the locking position of the securing piece 20 can be predetermined by a stop. For this purpose, or the like from the outside of the contact plate 13. project a stop pin 34 against which the rotary handle 33 runs both in the release position and in the locking position. The rotary handle 33 can have a can-shaped configuration with the can side open towards the stop body 34, the radial bars 35 to 39 (the other radial bars were not assigned a reference number for reasons of clarity) can run in the rotary handle 33, of which the radial bars 35 and 39, the approximately are offset from each other by 180 o , each form a stop for the stop pin in the release position or in the locking position. 9, the stop pin is shown in dash-dot lines at the bottom left of the radial web 35, the rotary handle and thus the securing piece 20 being in the release position in which it can be pulled out or inserted. If you turn the rotary handle 33 in the direction of arrow 40, the rotary handle 30 passes over the stop pin 34 until its radial web 39 comes into contact with the stop pin. The radial webs 36, 37, 38 between them each have a recess 41 for the passage of the stop pin when the twist grip is turned.

Aus Fig. 11 geht eine andere Ausführungsform für das Sicherungsstück hervor. Wiederum durchgreift das Sicherungsstück 20a die Anlageplatte 13 od.dgl., wobei es sich um einen hin und her schraubbaren Gewindebolzen handelt.11 shows another embodiment for the securing piece. Again, the securing piece 20a passes through the contact plate 13 or the like, which is a threaded bolt that can be screwed back and forth.

In seiner in der Anlageplatte 13 od.dgl. vorgeschraubten, wirksamen Stellung dringt er durch das Sicherungsloch 19a der äußeren Wand 7 sowie durch das zugewandte Verstelloch 9. Hebt man das Oberteil 6 an, schlägt das Sicherungsstück 20a am Lochrand des Verstelloches 9 an, bevor das Oberteil 6 so weit angehoben ist, daß die Steckglieder 11 aus den Verstellöchern austreten können. Verschraubt man das Sicherungsstück 20a nach außen, gibt er das zugeordnete Verstelloch 9 frei, so daß die Anlageplatte 13 mit den Steckgliedern 11 weggenommen und die neue Höheneinstellung des Standbeins vorgenommen werden kann. Die Anlageplatte 13 od.dgl. besitzt eine Gewindebohrung für den Gewindebolzen 20a, die von einer drehfest in die Anlageplatte 13 od.dgl. eingesetzten Gewindemutter 42 gebildet werden kann. Wiederum steht das Sicherungsstück 20a von einem tellerartig geformten Drehgriff 33a ab.In his or the like in the contact plate 13. pre-screwed, effective position, it penetrates through the securing hole 19a of the outer wall 7 and through the facing adjustment hole 9. If the upper part 6 is raised, the securing piece 20a strikes the edge of the hole in the adjusting hole 9 before the upper part 6 is raised so far that the Plug-in members 11 can emerge from the adjustment holes. If you screw the locking piece 20a outwards, it releases the associated adjustment hole 9, so that the contact plate 13 with the plug-in members 11 can be removed and the new height adjustment of the supporting leg can be carried out. The contact plate 13 or the like. has a threaded hole for the threaded bolt 20a or the like from a rotationally fixed in the contact plate 13. inserted nut 42 can be formed. Again, the securing piece 20a protrudes from a plate-shaped rotary handle 33a.

Als Verstelloch, durch das das Sicherungsstück 20; 20a greift, kann jedes Verstelloch 9 dieser Lochreihe verwendet werden. Hierzu ist das Sicherungsstück 20; 20a an der Anlageplatte 13 od.dgl. an der zutreffenden Stelle gelagert. Das Sicherungsloch 19; 19a der äußeren Wand 6 ist dagegen ein zusätzliches Loch, dessen Abstand zu den Feststellöchern 10 nicht dem Rasterabstand der Verstelllöcher 9 entspricht. Dies rührt daher, daß die Feststelllöcher 10 vor dem Einsetzen der Steckglieder 11 (Fig. 3) mit den Verstellöchern 9 fluchten und bei über die Steckglieder fixiertem Oberteil 6 in Höhenrichtung versetzt zu den verstellöchern angeordnet sind (Fig. 4), während das Sicherungsloch 19; 19a bei durch die Steckglieder fixierter Höhenlage mit dem jeweils zugewandten Verstelloch 9 fluchten muß.As adjustment hole through which the securing piece 20; 20a engages, each adjustment hole 9 of this row of holes can be used. For this purpose, the securing piece 20; 20a on the contact plate 13 or the like. stored in the appropriate place. The securing hole 19; 19a of the outer wall 6, on the other hand, is an additional hole whose distance to the fixing holes 10 does not correspond to the grid spacing of the adjusting holes 9. This is due to the fact that the locking holes 10 are aligned with the adjustment holes 9 before the insertion of the plug-in members 11 (FIG. 3) and are offset in height with the upper part 6 fixed via the plug-in links to the adjustment holes (FIG. 4), while the locking hole 19 ; 19a at through the plug-in links fixed altitude with the facing adjustment hole 9 must be aligned.
