Abstract

The support foot for the furniture leg (1) has an outer thread (5) which is threaded into the threaded ring (2) fitted to the bottom of the leg. A tensioner ring (8) between the threaded ring and a clamping ring (6), with inner thread, controls the relative spacing of the threaded ring and the clamping ring. The tensioner ring is released to allow easy adjustment of the threaded foot and is moved into the tension position to force the threaded ring and the clamping ring to secure grip the thread, without play. The clamping ring is rotationally coupled to the threaded ring by axial tags. The tensioner ring is coupled to the threaded ring by wedge profiles which alter the relative spacing of the two ring by rotating the tensioner ring. An outer sleeve (9) covers the adjustable foot and is slid up to effect the adjustment.

Description

Es sind bereits Höhenverstellvorrichtungen für Tische bekannt, bei denen ein mit Außengewinde versehener Fuß im Innengewinde eines Rohres drehbar gelagert ist, wobei durch die Verdrehung eines der Teile eine Höhenverstellung erfolgt. Derartige Tischfüße mit einem größeren Verstellbereich neigen jedoch einerseits durch das immer vorhandene Spiel im Gewinde und andererseits durch die geringe Überdeckung der Gewindeteile im Endbereich zum Wackeln. Da dies bei Tischen, insbesondere bei Schreibtischen, äußerst nachteilig ist, liegt der vorliegenden Erfindung die Aufgabe zugrunde, das zum Verstellen des Fußes notwendige Spiel zwischen den Gewindeteilen auf einfache Weise auszuschalten, so daß der Fuß auch im Endbereich so stabilisiert ist, daß ein fester Stand des Tisches in jeder Höhenlage erreicht wird.Height adjustment devices for tables are already known, in which a foot provided with an external thread is rotatably mounted in the internal thread of a tube, wherein the height is adjusted by rotating one of the parts. Such table feet with a larger adjustment range tend to wobble on the one hand due to the always existing play in the thread and on the other hand due to the slight overlap of the threaded parts in the end region. As this is extremely disadvantageous for tables, especially desks is, the present invention has for its object to turn off the necessary play for adjusting the foot between the threaded parts, so that the foot is stabilized in the end area so that a firm stand of the table is achieved at any height.

Hierzu ist erfindungsgemäß bei einer Verstellvorrichtung der beschriebenen Art das Innen- oder das Außengewinde einerseits auf das Rohr oder den Fuß und andererseits auf eine Spannhülse aufgeteilt, welche unverdrehbar aber axial verschiebbar mit dem das andere Gewindeteil aufweisenden Rohr oder Fuß verbunden ist, wobei zwischen diesem und der Spannhülse ein dieselben durch Drehverstellung auseinanderpressender Spannring gelagert ist. Durch die Verdrehung des Spannringes werden die beiden Gewindeteile so auseinandergedrückt, daß das Innen- und das Außengewinde gegenseitig verklemmen. Um die Vorrichtung in eine andere Höhenlage zu bringen, muß dann lediglich der Spannring in die entgegengesetzte Richtung gedreht werden, so daß sich wiederum ein Spiel zwischen den beiden aufgeteilten Gewindeteilen ergibt und eine Verstellung ermöglicht wird. Dabei ist es grundsätzlich nicht von Bedeutung, ob das Innen- oder das Außengewinde aufgeteilt wird und auf welchen der gegeneinander verstellbaren Teile das aufgeteilte Gewinde angeordnet ist.For this purpose, according to the invention, in an adjusting device of the type described, the internal or external thread is divided on the one hand onto the pipe or the foot and on the other hand onto a clamping sleeve, which is non-rotatably but axially displaceably connected to the pipe or foot having the other threaded part, between this and the clamping sleeve is supported by a clamping ring that presses it apart by rotating adjustment. By turning the clamping ring, the two threaded parts are pressed apart so that the internal and external threads jam each other. In order to bring the device to a different altitude, the clamping ring then only has to be rotated in the opposite direction, so that there is again play between the two divided threaded parts and adjustment is possible. It is basically irrelevant whether the internal or the external thread is divided and on which of the mutually adjustable parts the split thread is arranged.

Nach einem weiteren Merkmal der Erfindung weisen der Spannring ein oder mehrere Keile und das mit dem aufgeteilten Gewinde versehene Teil sowie die Spannhülse Gleitflächen für den oder die Keile auf. Bei einer bevorzugten Ausführungsform sind der Fuß mit Außengewinde und das Rohr sowie die Spannhülse mit dem aufgeteilten Innengewinde versehen.According to a further feature of the invention, the clamping ring has one or more wedges and the part provided with the split thread and the clamping sleeve have sliding surfaces for the wedge or wedges. In a preferred embodiment, the foot is with Provide the external thread and the pipe as well as the adapter sleeve with the split internal thread.

Eine besonders einfache Ausführungsform ergibt sich, wenn der Innengewindeteil des Rohres und die Gleitflächen für die Keile an einer im Rohr angeordneten Einpreßhülse vorgesehen sind. Auf diese Weise kann man jedes beliebige Rohr ohne besondere Bearbeitung für diesen Zweck verwenden.A particularly simple embodiment is obtained if the internal thread part of the tube and the sliding surfaces for the wedges are provided on a press-in sleeve arranged in the tube. In this way, any tube can be used for this purpose without special processing.

Zur Verbindung der Spannhülse in Drehrichtung mit der Einpreßhülse, bei axialer Beweglichkeit gegeneinander, ist die Spannhülse mit axial überstehendem Ansätzen versehen, welche in entsprechende Ausnehmungen in der Einpreßhülse eingreifen. Da ein vollständiges Herausdrehen des Fußes aus dem Rohr bzw. der Einpreßhülse verhindert werden soll, ist der Fuß an seinem dem Rohr zugewandten Ende mit einem Sicherungszapfen versehen, welcher in den Gewindebereich hineinragt. Um ein Verschmutzen von Kleidungsstücken an dem unter Umständen mit Schmiermittel versehenen Gewinde des Fußes zu verhindern, trägt dieser eine Abdeckung, welche über das Rohr hinausragt und auf diesem verschiebbar ist. Weiterhin ist es zweckmäßig, wenn der Benutzer auf einfache Weise das Maß der Höhenverstellung erkennen kann. Zu diesem Zwecke ist an der Einpreßhülse eine Rastnase vorgesehen, welche mit einer Längsnut des Fußes zusammenwirkt. Bei jeder vollständigen Umdrehung des Fußes ergibt sich dann eine genau definierte Raststellung. Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung. Es stellen dar:

To connect the adapter sleeve in the direction of rotation with the press-in sleeve, with axial mobility relative to one another, the adapter sleeve is provided with axially projecting projections which engage in corresponding recesses in the press-in sleeve. Since a complete unscrewing of the foot from the pipe or the press-in sleeve is to be prevented, the foot is provided at its end facing the pipe with a safety pin which projects into the threaded area. In order to prevent clothing from getting dirty on the thread of the foot, which may be provided with lubricant, this carries a cover which projects beyond the tube and can be displaced thereon. Furthermore, it is expedient if the user can easily recognize the degree of height adjustment. For this purpose, a locking lug is provided on the press-in sleeve, which interacts with a longitudinal groove of the foot. With each complete turn of the foot there is a precisely defined locking position. The drawing shows an embodiment of the invention. They represent:

Die Verstellvorrichtung nach Figur 1 besteht aus einem Rohr 1, welches beispielsweise in nicht dargestellter Weise an einer Tischplatte befestigt ist. In das untere Ende des Rohres 1 ist eine Einpreßhülse 2 eingesetzt, in deren Innengewinde 3 ein Tischfuß 4 mit Außengewinde 5 eingeschraubt ist. Außerdem ist auf dem Außengewinde 5 des Tischfußes 4 noch eine Spannhülse 6 mit Innengewinde 7 aufgeschraubt, wobei das Innengewindeteil 3 und das Innengewindeteil 7 Teile eines Gesamtgewindes darstellen. Zwischen der Einpreißhülse 2 und der Spannhülse 6 befindet sich noch ein Spannring 8, dessen Funktionen weiter unten erläutert werden. Auf dem Rohr 1 ist eine ebenfalls rohrförmige Abdeckung 9 verschiebbar gelagert, welche wie Figur 2 zeigt mit dem unteren Ende 10 des Fußes 5 fest verbunden ist.The adjusting device according to FIG. 1 consists of a tube 1, which is fastened, for example, to a table top in a manner not shown. In the lower end of the tube 1, a press-in sleeve 2 is inserted, in the internal thread 3 of which a table base 4 with an external thread 5 is screwed. In addition, an adapter sleeve 6 with an internal thread 7 is screwed onto the external thread 5 of the table base 4, the internal thread part 3 and the internal thread part 7 representing parts of an overall thread. Between the crimping sleeve 2 and the clamping sleeve 6 there is still a clamping ring 8, the functions of which are explained further below. On the tube 1 there is also a tubular cover 9 slidably mounted, which as shown in Figure 2 is firmly connected to the lower end 10 of the foot 5.

Zur Höhenverstellung des Fußes 5 wird dieser in die Spannhülse 6 und die Einpreßhülse 2 mehr oder weniger tief eingeschraubt. Die Spannhülse 6 ist dabei mit der Einpreßhülse 2 drehbar aber axial verschiebbar verbunden. Dazu greifen Ansätze 11 der Spannhülse 6 in Ausnehmungen 12 der Einpreßhülse 2 ein, so daß beide Teile in Drehrichtung verbunden sind, jedoch noch ein größeres axiales Spiel möglich ist. Der Spannring 8 ist drehbar zwischen der Einpreßhülse 2 und der Spannhülse 6 gelagert und mit 3 Keilen 13 versehen, welche auf den Gleitflächen 14 der Einpreßhülse 2 und den Gleitflächen 15 der Spannhülse 6 liegen. Durch Verdrehen des Spannringes pressen die Keile 13 die Spannhülse 6 und die Einpreßhülse 2 auseinander, so daß keinerlei Spiel zwischen dem Außengewinde 5 des Tischfußes 4 und den Innengewindeteilen 3 und 7 der Einpreßhülse 2 in der Spannhülse 7 mehr besteht und die Gewinde miteinander verklemmt werden. Auf diese Weise wird eine stabile Verbindung zwischen dem Rohr 1 und dem Fuß 5 geschaffen.To adjust the height of the foot 5, it is screwed more or less deeply into the clamping sleeve 6 and the press-in sleeve 2. The clamping sleeve 6 is rotatably connected to the press-in sleeve 2 but axially displaceable. For this purpose approaches 11 of the clamping sleeve 6 engage in recesses 12 of the press-in sleeve 2, so that both parts are connected in the direction of rotation, but still greater axial play is possible. The clamping ring 8 is rotatably mounted between the press-in sleeve 2 and the clamping sleeve 6 and provided with 3 wedges 13 which lie on the sliding surfaces 14 of the pressing-in sleeve 2 and the sliding surfaces 15 of the clamping sleeve 6. By turning the clamping ring, the wedges 13 press the clamping sleeve 6 and the press-in sleeve 2 apart, so that there is no more play between the external thread 5 of the table leg 4 and the internal thread parts 3 and 7 of the press-in sleeve 2 in the clamping sleeve 7 and the threads are clamped together. In this way, a stable connection between the tube 1 and the foot 5 is created.

Um die beiden letztgenannten Teile wieder gegeneinander zu verstellen, wird der Spannring 8 in die entgegengesetzte Richtung gedreht, so daß die Spannhülse 6 wieder mit Spiel auf dem Außengewinde 5 des Fußes 4 zu liegen kommt.To adjust the latter two parts again against each other, the clamping ring 8 is rotated in the opposite direction, so that the clamping sleeve 6 comes to rest on the external thread 5 of the foot 4 with play.

Zur genauen Höheneinstellung ist auf dem Fuß 4 eine Skala 16 vorgesehen. Außerdem weist die Einpreßhülse 2 noch eine Rastnase 17 auf, welche mit einer aus der Zeichnung nicht zu ersehenden der Skala 16 gegenüberliegenden Nut des Fußes 4 zusammenwirkt, so daß bei jeder vollen Umdrehung eine Raststellung erreicht wird, und auf diese Art und Weise eine genaue Höheneinstellung möglich ist.A scale 16 is provided on the foot 4 for precise height adjustment. In addition, the press-in sleeve 2 still has a locking lug 17, which with a not seen from the drawing Scale 16 opposite groove of the foot 4 cooperates so that a stop position is reached with each full rotation, and in this way an accurate height adjustment is possible.

Der Fuß 4 weist an seinem der Einpreßhülse 2 zugewandten Ende einen Sicherungszapfen 18 auf, welcher in das Gewinde 5 des Fußes 4 hineinragt und ein vollständiges Herausdrehen des Fußes 4 zwangsläufig verhindert.The foot 4 has at its end facing the press-in sleeve 2 a securing pin 18 which projects into the thread 5 of the foot 4 and inevitably prevents the foot 4 from being completely unscrewed.
