Description

Die vorliegende Erfindung betrifft eine mit Füßen versehene, verschwenkbare Platte gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a footed, pivotable plate according to the preamble of claim 1.

Derartige Platten, vorzugsweise Tischplatten, finden beispielsweise als Klapptische Verwendung, wie sie in vielen Bereichen zum Einsatz kommen.Such plates, preferably table tops, find use, for example, as folding tables, as they are used in many areas.

Dabei kann eine Verschwenkung der Platte in eine Schräglage gewünscht sein, wie sie bei Benutzung als Zeichen- oder Arbeitstisch sinnvoll ist oder aber eine Verschwenkung in eine vertikale Position, um eine Vielzahl von Tischen bei Nichtgebrauch platzsparend voreinander stellen zu können.In this case, a pivoting of the plate may be desired in an inclined position, as it makes sense when used as a drawing or working table or a pivoting in a vertical position to place a variety of tables when not in use to save space.

Hierzu ist es bekannt, nicht nur die Tischplatte entsprechend zu verschwenken, sondern auch die Füße so zu verdrehen, daß sie einen kleinstmöglichen Raum einnehmen, d. h., daß sie geringstmöglich über die dann vertikal ausgerichtete Tischplatte vorstehen.For this purpose, it is known not only to pivot the table according to, but also to rotate the feet so that they occupy the smallest possible space, ie, that they least protrude over the then vertically oriented table top.

Bislang wird dies dadurch erreicht, daß die Tischplatte an einer nur dieser zugeord-neten Schwenkachse befestigt ist, während die Füße an separaten Schwenkachsen gelagert sind. In jedem Fall müssen die Tischplatte und die Füße jeweils für sich in die entsprechende Endposition verschwenkt werden.So far, this is achieved in that the table top is attached to a only this zugeord-Neten pivot axis, while the feet are mounted on separate pivot axes. In any case, the table top and the feet must be pivoted in each case in the appropriate end position.

Ein solcher Klapptisch ist beispielsweise aus der DE 94 17 585 U1 bekannt. Allerdings ist die Handhabung dieses Tisches nur äußerst umständlich zu bewerkstelligen, da beim Verdrehen der Füße genau darauf geachtet werden muß, daß die abzuklappende Tischplatte, die im weiteren Verlauf des Verschwenkens der Füße ihre Unterstützung verliert, gehalten wird bzw. deren Schwenken in eine Nichtgebrauchsposition durch manuelles Nachführen gesichert wird.Such a folding table is for example from the DE 94 17 585 U1 known. However, the handling of this table is extremely cumbersome to accomplish, as the rotation of the feet must be taken to ensure that the folded table top, which loses its support in the further course of the pivoting of the feet is held or their pivoting in a non-use position manual tracking is saved.

Zum Aufschwenken der Tischplatte in eine Gebrauchsposition muß diese zunächst manuell angehoben werden. Danach erfolgt die Verschwenkung der Füße. Für eine wirklich befriedigende Verschwenkung der Tischplatte ist diese Konstruktion nicht geeignet.To pivot the table top in a position of use, this must first be manually raised. Thereafter, the pivoting of the feet. For a really satisfactory pivoting of the table top, this construction is not suitable.

Dies trifft gleichermaßen auf einen Tisch zu, der aus der DE 198 37 987 A 1 bekannt ist. Hier ist zwar eine Kopplung der Schwenkbewegung der Füße und der Tischplatte vorgesehen, jedoch ist diese gleichzeitige Verschwenkung nur mit einem erheblichen Kraftaufwand möglich. Hinzu kommt, daß diese Zwangsführung konstruktiv sehr aufwendig ausgebildet ist und für den gedachten Einsatzzweck wenig praktikabel.This applies equally to a table, which is known from DE 198 37 987 A1. Here, although a coupling of the pivotal movement of the feet and the table top is provided, but this simultaneous pivoting is possible only with a considerable effort. In addition, this forced operation is structurally very complicated and not very practical for the intended purpose.

Die CH-A-681850 offenbart ein klappbares Gestell, mit über kugelgelenke angelenkten Streben.The CH-A-681 850 discloses a hinged frame, with hinged over ball joints struts.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Platte mit Füßen der gattungsgemäßen Art so auszubilden, daß mit geringstmöglichem konstruktiven Aufwand eine einfache und bequeme, gleichzeitige Verschwenkung der Platte und der Füße möglich ist.The present invention is therefore based on the object, a plate with feet of the generic type so that with the least possible design effort a simple and comfortable, simultaneous pivoting of the plate and the feet is possible.

Diese Aufgabe wird durch eine Platte gelöst, die die Merkmale des Anspruchs 1 aufweist.This object is achieved by a plate having the features of claim 1.

Durch diese konstruktive Ausgestaltung wird auf einfache, jedoch äußerst wirkungsvolle Art eine gekoppelte Schwenkbewegung der Platte einerseits und der Füße andererseits ermöglicht.This structural design is a simple, but extremely effective way a coupled pivoting movement of the plate on the one hand and the feet on the other hand allows.

Dabei besteht das Charakteristikum der Erfindung darin, daß die Schwenkachse im Sinne einer Raumachse sowohl die Führung für die Platte als auch für den zugeordneten Fuß bildet.The characteristic of the invention is that the pivot axis in the sense of a spatial axis forms both the guide for the plate and for the associated foot.

Zweckmäßigerweise wird die Schwenkachse fest mit der Platte verbunden. Prinzipiell ist jedoch auch eine feste Verbindung mit dem Fuß möglich, wobei in jedem Fall eine bestimmte Schwenkbewegung des Fußes und der Platte, abhängig voneinander, gegeben ist.Conveniently, the pivot axis is firmly connected to the plate. In principle, however, a firm connection with the foot is possible, wherein in each case a certain pivoting movement of the foot and the plate, depending on each other, is given.

Die Erfindung beschränkt sich nicht auf den Einsatz in einem Klapptisch, sondern ist durchaus auch einsetzbar in Staffeleien, Tafeln, Lesehilfen oder Halterungen jedweder Art, bei denen es auf eine einfache Verschwenkung der Platte ankommt, die durchaus in unterschiedlichen Winkelstellungen festsetzbar sein kann. Dies kann beispielsweise durch eine Rasterung der Schwenkachse erfolgen. Denkbar ist aber auch, eine stufenlose Verstellung zu ermöglichten, bei der dann die Schwenkachse in der gewünschten Position, beispielsweise durch eine Bremse oder dergleichen, festsetzbar ist.The invention is not limited to use in a folding table, but is also quite applicable in easels, panels, reading aids or brackets of any kind in which it depends on a simple pivoting of the plate, which may well be set in different angular positions. This can be done for example by a screening of the pivot axis. It is also conceivable to allow a continuous adjustment, in which then the pivot axis in the desired position, for example by a brake or the like, can be fixed.

Weiter ist die Erfindung auch bei einem Tisch einsetzbar, der lediglich einen Fuß aufweist, wobei dann vorzugsweise mindestens drei Streben oder ein entsprechend ausgebildeter Standfuß vorgesehen sind, mit denen er sich fußbodenseitig abstützt.Further, the invention is also applicable to a table having only one foot, then preferably at least three struts or a suitably trained stand are provided, with which he is supported on the floor side.

Auch können die Füße mit Rollen versehen sein, wodurch sich eine besonders einfache Verschwenkung um eine etwa vertikale Achse erreichen läßt, bei der der Fuß von einer Position, die die größtmögliche Auflagesicherheit bietet, wenn die Platte in eine horizontale oder nahezu horizontale Lage verschwenkt ist, in eine Position, in der der Fuß die kleinstmögliche Stellfläche einnimmt.Also, the feet may be provided with rollers, whereby a particularly simple pivoting about an approximately vertical axis can be achieved, in which the foot of a position that provides the greatest possible safety when the plate is pivoted in a horizontal or nearly horizontal position, in a position in which the foot occupies the smallest possible footprint.

Im letzteren Fall, bei dem die Platte in eine vertikale Nichtgebrauchsstellung verschwenkt ist, ist eine äußerst platzsparende Lagerung vieler aneinander stehender Tische möglich.In the latter case, in which the plate is pivoted into a vertical non-use position, a very space-saving storage of many adjacent tables is possible.

Nach der Erfindung ist vorteilhafterweise vorgesehen, dass die Schwenkachse aus einer trichterförmigen Hülse besteht, die fest mit der Platte verbunden ist, sowie einem darin gelagerten Kegelteil, das an einem Fuß angeschlossen ist. Die gemeinsame Mittellängsachse, die gleichzeitig eine Symmetrieachse bildet, ist räumlich schräg zur Platte angeordnet, wobei bei zwei vorgesehenen Füßen die Symmetrieachsen etwa aufeinander zugerichtet verlaufen, so dass bei einer Verschwenkung der Platte von einer horizontalen in eine vertikale Position die außen liegenden Füße bzw. ihre Stellstreben aufeinander zu gedreht werden. Bei einer genau horizontalen oder vertikalen Lage der Platte sind die Füße vertikal ausgerichtet.According to the invention is advantageously provided that the pivot axis consists of a funnel-shaped sleeve which is fixedly connected to the plate, and a cone member mounted therein, which is connected to a foot. The common central longitudinal axis, which simultaneously forms an axis of symmetry, is spatially arranged obliquely to the plate, wherein at two provided feet, the symmetry axes are approximately aligned with each other, so that when pivoting the plate from a horizontal to a vertical position, the outer feet or their Stellstreben be turned towards each other. In an exactly horizontal or vertical position of the plate, the feet are aligned vertically.

Die Hülse kann gemeinsam mit einer an der Platte befestigten Aufnahme als dekoratives Element ausgebildet sein, das insoweit bei Verwendung einer Platte aus Glas den Gesamteindruck des in diesem Falle Tisches in gestalterischer Hinsicht beeinflusst.The sleeve may be formed together with a receptacle attached to the plate as a decorative element, which influences the extent of the design of the table in this case when using a plate made of glass.

Weitere vorteilhafte Ausbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet. Further advantageous embodiments of the invention are characterized in the subclaims .

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der beigefügten Zeichnungen beschrieben.An embodiment of the invention will be described below with reference to the accompanying drawings.

In den Figuren 1-4 ist ein Klapptisch dargestellt, der in seinem Grundaufbau aus einer als Tischplatte ausgebildeten Platte 1 und zwei Füßen 2 besteht, die über Schwenkbeschläge 5 mit der Platte 1 verbunden sind, wobei sowohl die Platte 1 wie auch die Füße 2 bewegungsabhängig von einer Gebrauchsstellung, wie sie in den Figuren 1 und 2 gezeigt ist, in eine Nichtgebrauchsstellung, entsprechend der Figur 4 verschwenkbar ist. In letzterer ist die Platte 1 in eine vertikale Stellung gebracht und die Füße 2 so weit eingeschwenkt, daß sie eine geringstmögliche Stellfläche einnehmen.In the Figures 1-4 a folding table is shown, which consists in its basic construction of a plate formed as a plate 1 and two feet 2, which are connected via pivot fittings 5 with the plate 1, wherein both the plate 1 as well as the feet 2 movement dependent on a use position, as they in the FIGS. 1 and 2 is shown in a non-use position, according to the FIG. 4 is pivotable. In the latter, the plate 1 is brought into a vertical position and the feet 2 pivoted so far that they occupy a minimum possible footprint.

Jeder Fuß 2 besteht aus einem rohrförmigen Holm 4, an dessen der Platte 1 abgewandtern Ende zwei Stellstreben 3 befestigt sind.Each foot 2 consists of a tubular bar 4, at the end of the plate 1 facing away from two adjusting struts 3 are attached.

Jeder Schwenkbeschlag 5 ist mittels einer Aufnahme 6 an der Unterseite der Platte 1 befestigt und durch einen Zapfen 7, der in den Holm 4 hineinragt und durch eine Flügelschraube 8 (Figur 3) darin verdrehsicher gehalten ist, an dem Fuß 2.Each swivel fitting 5 is fastened by means of a receptacle 6 on the underside of the plate 1 and by a pin 7, which projects into the spar 4 and by a thumb screw 8 (Fig. FIG. 3 ) held therein against rotation, on the foot of the second

In der Figur 3 ist eine schräge Lage der Platte 1 dargestellt, wie sie beispielsweise bei Verwendung als Arbeitstisch sinnvoll ist.In the FIG. 3 an oblique position of the plate 1 is shown, as it makes sense when used as a work table, for example.

Wie die Figur 6 sehr deutlich wiedergibt, weist der Schwenkbeschlag 5 im vorliegenden Ausführungsbeispiel eine mit der Aufnahme 6 fest verbundene Hülse 12 auf, die trichterförmig ausgebildet ist und dabei einen konischen, sich zur Tischplatte hin verjüngende Bereich aufweist, in dem ein Kegelteil 13 gelagert ist, an das der Zapfen 7 angeschlossen ist, der, wie beschrieben, mit dem Holm 4 verbunden ist.As the FIG. 6 reproduces very clearly, the pivot fitting 5 in the present embodiment, a firmly connected to the receptacle 6 sleeve 12 which is funnel-shaped and has a conical, tapering towards the table top area in which a cone portion 13 is mounted, to which Pin 7 is connected, which, as described, is connected to the spar 4.

Prinzipiell bilden die Hülse 12 und das Kegelteil 13 mit ihrer gemeinsamen Mittellängsachse, die räumlich schräg zur Platte 1 angeordnet ist, eine Schwenkachse, um die sowohl die Platte 1 als auch der Fuß 2 schwenkbar sind.In principle, form the sleeve 12 and the cone member 13 with its common central longitudinal axis, which is spatially arranged obliquely to the plate 1, a pivot axis about which both the plate 1 and the foot 2 are pivotable.

Hierbei dreht sich das Kegelteil 13 in der feststehenden Hülse 12, so daß die beiden sich gegenüber liegenden Füße aufeinander zu verschwenkt werden, bis sie eine Endstellung einnehmen, wie sie in der Figur 5 gezeigt ist. Darin ist zu erkennen, daß die Stellstreben 3 so angeordnet sind, daß ein Einschieben benachbarter Klapptische zu einem geringstmöglichen Abstand möglich ist.Here, the cone member 13 rotates in the stationary sleeve 12, so that the two opposite feet are pivoted toward each other until they occupy an end position, as shown in the FIG. 5 is shown. It can be seen that the adjusting struts 3 are arranged so that an insertion of adjacent folding tables to a minimum possible distance is possible.

Das Kegelteil 13 des Schwenkbeschlages 5 nach Figur 6 ist drehbar auf einem Spannbolzen 10 gelagert, der in die Hülse 12 eingeschraubt ist, und zwar in dem der Platte 1 zugewandten Ende.The cone part 13 of the pivot fitting 5 after FIG. 6 is rotatably mounted on a clamping bolt 10 which is screwed into the sleeve 12, in the plate 1 facing the end.

In diesem Endbereich ist auf dem Spannbolzen 10 eine Druckfeder 14 geführt, die sich einerseits an der Hülse 12 und andererseits am Kegelteil 13 abstützt.In this end region, a compression spring 14 is guided on the clamping bolt 10, which is supported on the one hand on the sleeve 12 and on the other hand on the cone part 13.

An dem der Druckfeder 14 gegenüber liegenden Ende ist an dem Spannbolzen 10 schwenkbar ein Hebel 9 angeschlossen, der im Verbindungsbereich mit dem Spannbolzen 10 einen Exzenter 11 aufweist, der an das Kegelteil 13 anpreßbar ist.At the opposite end of the compression spring 14, a lever 9 is pivotally connected to the clamping bolt 10, which has an eccentric 11 in the connection region with the clamping bolt 10, which can be pressed against the cone part 13.

Zur Festsetzung des Kegelteiles 13 in der Hülse 12, um so eine bestimmte Position der Platte 2 zu arretieren, wird der Hebel 9 so verschwenkt, daß sich der Exzenter 11 an das Kegelteil 13 andrückt, wobei gleichzeitig die konische Mantelfläche des Kegelteiles 13 an die Innenfläche der Hülse 12 gepreßt wird. Hierdurch wird ein Reibschluß erreicht, der eine Festsetzung der Platte in der entsprechenden Position sichert. Zur Erhöhung der Reibwirkung zwischen dem Kegelteil 13 und der Hülse 12 sind in dem Kegelteil 13 Bremsbeläge 15 angeordnet, die einen höheren Reibungskoeffizienten als das Material des Kegelteiles 13 aufweisen.To fix the cone member 13 in the sleeve 12, so as to lock a certain position of the plate 2, the lever 9 is pivoted so that the eccentric 11 presses against the cone member 13, wherein at the same time the conical surface of the cone member 13 to the inner surface the sleeve 12 is pressed. As a result, a frictional engagement is achieved, which ensures a fixing of the plate in the appropriate position. To increase the friction between the cone portion 13 and the sleeve 12 13 brake pads 15 are arranged in the cone portion having a higher coefficient of friction than the material of the cone portion 13.

Zum Lösen des Reibschlusses, um die Platte 1 frei verschwenken zu können, wird durch Betätigen des Hebels 9 der Exzenter 11 aus seiner Spannstellung gelöst, so daß durch die Druckfeder 14 das Kegelteil 13 auf dem Spannbolzen 10 so weit axial verschoben wird, daß das Kegelteil 13 aus der Anlage mit der Hülse 12 gelöst wird.To release the frictional engagement in order to pivot the plate 1 freely, the eccentric 11 is released from its clamping position by actuating the lever 9, so that the cone member 13 is displaced so far axially on the clamping bolt 10 by the compression spring 14, that the cone part 13 is released from the system with the sleeve 12.

Dieses Ausführungsbeispiel des Schwenkbeschlages 5 bietet die Möglichkeit einer stufenlosen Verschwenkung der Platte 1, wobei, wie erwähnt, die Füße 2 ebenfalls verschwenkt werden, und zwar um eine im wesentlichen vertikale Achse.This embodiment of the swivel fitting 5 offers the possibility of a stepless pivoting of the plate 1, wherein, as mentioned, the feet 2 are also pivoted, namely about a substantially vertical axis.

Diese Verschwenkung des Fußes 2 erfolgt durch die räumliche Lageveränderung der Schwenkachse, in diesem Fall der Hülse 12 des Kegelteiles 13 durch die Verschwenkung der Platte 1.This pivoting of the foot 2 is effected by the spatial position change of the pivot axis, in this case the sleeve 12 of the cone member 13 by the pivoting of the plate. 1

Dabei paßt sich der Schwenkwinkel den bodenseitigen Gegebenheiten an, wodurch wie durch eine Federung Unebenheiten ausgeglichen werden und eine hohe Standsicherheit erreicht wird.In this case, the pivot angle adjusts the bottom conditions, which are compensated as by a suspension bumps and high stability is achieved.
