Definitions

  • the invention relates to an adjustment tool for adjustment parts of base feet for furniture, such as kitchen cabinets or the like, which are provided with teeth, for example, with a headpiece having a receptacle for the adjustment part and a gearwheel connection, and with a handle connected to the headpiece.
  • Base feet for furniture such as kitchen cupboard furniture have a height-adjustable adjustment part in order to adapt the furniture exactly to the local installation conditions of the furniture.
  • precise adjustment work must be carried out on site in order to precisely adjust and align the furniture to be set up using base feet or similar supporting parts.
  • this adjustment tool only works if the teeth on the adjustment part of the base foot and the adjustment tool are aligned at the same height, which z. B. is not the case if z. B. a cupboard in a z.

  • the adjustment tool of the type mentioned is characterized in that the teeth of the gear connection of the head piece perpendicular to a horizontal longitudinal center plane of the adjustment tool and therefore are aligned parallel to the vertical extension of an adjustment part of a base foot or the like rigid connection is connected to a further gear, which is driven by a worm wheel from the electric motor drive.
  • all the gears are therefore arranged vertically and rotate about parallel axes.
  • the axis of the adjusting part is also aligned parallel thereto, so that these gears together form a gear that can step down the driving force generated by the electric motor drive.
  • the direction of the driving force is reversed from a horizontally aligned direction to a vertically aligned direction and therefore parallel to the toothing that is provided on the adjustment part.
  • the driving force of the electric motor drive is transmitted via a pinion shaft (worm wheel), the axis of the pinion shaft not being aligned parallel to the axes of the gear wheels, but perpendicular to them.
  • the axis of rotation of the pinion shaft is deflected from horizontal to the vertical axis of rotation of the gears. This deflection is carried out by two gear wheels that are firmly and inextricably linked to one another. Due to the forces arising during operation, this area of the gear pair is designed to be particularly stiff. A reduction gear is thereby formed.
  • the contact surfaces of the respective toothed surfaces are significantly increased compared to the adjustment tools according to the prior art. Therefore, the introduction of force through the two drive gears is significantly improved.
  • the total friction losses that occur are significantly reduced overall. Due to the vertical toothing on the adjustment surfaces, this can be made significantly longer than the horizontally aligned toothing in the prior art. This means that even larger unevennesses in the floor can be compensated with the adjustment tool, so that a base foot and the adjustment tool according to the invention do not have to be aligned at the same height, so that a base foot can also be supported on a floor surface lower than the height at which the adjustment tool acts.

In addition, a larger gear coupling is to be realized.

Description

Die Erfindung bezieht sich auf ein Verstellwerkzeug für insbesondere mit einer Verzahnung versehene Verstellteile von Sockelfüßen für Möbel wie beispielsweise Küchenschrankmöbel oder dgl. mit einem eine Aufnahme für das Verstellteil sowie eine Zahnradverbindung aufweisenden Kopfstück sowie mit einem mit dem Kopfstück verbundenen Handgriff.The invention relates to an adjustment tool for adjustment parts of base feet for furniture, such as kitchen cabinets or the like, which are provided with teeth, for example, with a headpiece having a receptacle for the adjustment part and a gearwheel connection, and with a handle connected to the headpiece.

Sockelfüße für Möbel wie beispielsweise Küchenschrankmöbel weisen ein höhenverstellbares Verstellteil auf, um die Möbel exakt an die örtlichen Aufstellverhältnisse des Möbels anzupassen. Dazu sind exakte Justierarbeiten vor Ort durchzuführen, um die aufzustellenden Möbel über Sockelfüße oder dgl. Abstützteile exakt zu justieren und auszurichten.Base feet for furniture such as kitchen cupboard furniture have a height-adjustable adjustment part in order to adapt the furniture exactly to the local installation conditions of the furniture. For this purpose, precise adjustment work must be carried out on site in order to precisely adjust and align the furniture to be set up using base feet or similar supporting parts.

Da derartige Sockelfüße oder sonstige Abstützteile mitunter nur schwer zugänglich sind, ist aus der WO 2015/053637 A2 ein Verstellwerkzeug mit einem eine Aufnahme aufweisenden Kopfstück sowie mit einem mit dem Kopfstück verbundenen Handgriff versehen, der endseitig ein verdrehbares Bedienteil aufweist, über das über eine drehfeste Verbindung ein in die Aufnahme ragendes Zahnrad zu verdrehen ist. Mit diesem Zahnrad kämmt eine Verzahnung, die auf dem Verstellteil eines Sockelfußes vorgesehen ist, und zwar an einem äußeren 360°-Kragen, so dass bei dem Sockelfuß mit dem daran angeordneten Verstellteil diese Verzahnung im wesentlichen horizontal und mithin parallel zu einer Aufstellfläche ausgerichtet ist. Dies ist nachteilig, da das Zahnrad nur eine sehr klein bauende Verzahnungsfläche für die Verzahnung des Verstellteils hat und daher bereits geringe Bewegungen des Handgriffes ausreichen, um das Verstellwerkzeug von dem Zahnkranz des Verstellteiles zu entkoppeln. Zudem ist die Handhabung dieses Verstellwerkzeuges kompliziert, da es mit zwei Händen zu ergreifen ist, um einerseits den Handgriff zu halten und andererseits das Verdrehteil des Handgriffes zu verdrehen und damit zu bedienen, um überhaupt eine Verstellung herbeiführen zu können. Dies ist insbesondere schwierig in Bereichen von z. B. Sockelfüßen und dgl. Abstützteilen, die in hinteren Schrankbereichen vorzusehen sind. Durch die Verzahnung an dem 360°-Kragen fallen beim Verstellvorgang hohe Reibungsverluste an, was ebenfalls sehr nachteilig ist. Zudem funktioniert dieses Verstellwerkzeug nur dann, wenn die Verzahnung am Verstellteil des Sockelfußes und das Verstellwerkzeug höhengleich ausgerichtet sind, was z. B. dann nicht der Fall ist, wenn z. B. ein Schrankmöbel in einem z. B. nicht durchgefliesten Küchenraum aufzustellen ist und ein hinterer Sockelfuß auf einer nicht gefliesten Fläche abzustützen ist, ein vorderer Sockelfuß aber auf einer gefliesten Fläche mit der dadurch bedingten Höhendifferenz.Since such base feet or other supporting parts are sometimes difficult to access, is from the WO 2015/053637 A2 an adjustment tool provided with a headpiece having a receptacle and with a handle connected to the headpiece, which has a rotatable operating part at the end, via which a gear wheel projecting into the receptacle can be rotated via a non-rotatable connection. A toothing provided on the adjustment part of a base foot meshes with this gear, specifically on an outer 360° collar, so that on the base foot with the adjustment part arranged on it, this toothing is aligned essentially horizontally and therefore parallel to a mounting surface. This is disadvantageous because the gear has only a very small toothed surface for the toothing of the adjustment part and therefore even small movements of the handle are sufficient to decouple the adjustment tool from the ring gear of the adjustment part. In addition, the handling of this adjusting tool is complicated because it has to be grasped with two hands in order to hold the handle on the one hand and to turn the turning part of the handle on the other hand and thus operate it in order to be able to bring about an adjustment at all. This is particularly difficult in areas of z. B. base feet and the like. Supporting parts that are to be provided in the rear cabinet areas. The teeth on the 360° collar result in high friction losses during the adjustment process, which is also very disadvantageous. In addition, this adjustment tool only works if the teeth on the adjustment part of the base foot and the adjustment tool are aligned at the same height, which z. B. is not the case if z. B. a cupboard in a z. B. is to be set up in a kitchen room that is not tiled and a rear base foot is to be supported on a non-tiled surface, but a front base foot on a tiled surface with the resulting height difference.

Es ist Aufgabe der vorliegenden Erfindung, ein Verstellwerkzeug der eingangs genannten Art dahingehend zu verbessern, dass die Handhabung wesentlich vereinfacht ist.It is the object of the present invention to improve an adjusting tool of the type mentioned at the outset in such a way that handling is significantly simplified.

Zur Lösung dieser Aufgabe zeichnet sich das Verstellwerkzeug der eingangs genannten Art dadurch aus, dass die Zähne der Zahnradverbindung des Kopfstückes senkrecht zu einer horizontalen Längsmittelebene des Verstellwerkzeuges und mithin parallel zur Hocherstreckung eines Verstellteiles eines Sockelfußes oder dgl. Abstützelementes ausgerichtet sind, dass in der Aufnahme des Kopfstückes zwei Zahnräder zur Verstellung des Verstellteiles vorgesehen sind, die von einem gemeinsamen Zahnrad angetrieben sind, und dass das gemeinsame Zahnrad und/oder ein weiteres Zahnrad über eine starre Verbindung mit einem weiteren Zahnrad verbunden ist, das durch ein Schneckenrad von dem elektromotorischen Antrieb angetrieben ist.To solve this problem, the adjustment tool of the type mentioned is characterized in that the teeth of the gear connection of the head piece perpendicular to a horizontal longitudinal center plane of the adjustment tool and therefore are aligned parallel to the vertical extension of an adjustment part of a base foot or the like rigid connection is connected to a further gear, which is driven by a worm wheel from the electric motor drive.

Bei dem erfindungsgemäßen Verstellwerkzeug sind mithin alle Zahnräder vertikal angeordnet und drehen um parallele Achsen. Die Achse des Verstellteiles ist ebenfalls dazu parallel ausgerichtet, so dass diese Zahnräder insgesamt ein Getriebe ausbilden, das die von dem elektromotorischen Antrieb erzeugte Antriebskraft untersetzen kann. Zwischen der Antriebskraft des elektromotorischen Antriebes erfolgt eine Umkehr der Richtung der Antriebskraft aus einer horizontal ausgerichteten Richtung in eine vertikal ausgerichtete Richtung und mithin parallel zu Verzahnung, die an dem Verstellteil vorgesehen ist. Die Antriebskraftübertragung des elektromotorischen Antriebes erfolgt über eine Ritzelwelle (Schneckenrad), wobei die Achse der Ritzelwelle zu den Achsen der Zahnräder nicht parallel ausgerichtet ist, sondern senkrecht zu diesen. Dabei wird die Drehachse der Ritzelwelle von horizontal auf die vertikale Drehachse der Zahnräder umgelenkt. Diese Umlenkung erfolgt durch zwei fest und unlösbar miteinander verbundene Zahnräder. Aufgrund der im Betrieb entstehenden Kräfte ist dieser Bereich der Zahnradpaarung besonders steif ausgebildet. Dabei wird ein Untersetzungsgetriebe ausgebildet.In the adjustment tool according to the invention, all the gears are therefore arranged vertically and rotate about parallel axes. The axis of the adjusting part is also aligned parallel thereto, so that these gears together form a gear that can step down the driving force generated by the electric motor drive. Between the driving force of the electric motor drive, the direction of the driving force is reversed from a horizontally aligned direction to a vertically aligned direction and therefore parallel to the toothing that is provided on the adjustment part. The driving force of the electric motor drive is transmitted via a pinion shaft (worm wheel), the axis of the pinion shaft not being aligned parallel to the axes of the gear wheels, but perpendicular to them. The axis of rotation of the pinion shaft is deflected from horizontal to the vertical axis of rotation of the gears. This deflection is carried out by two gear wheels that are firmly and inextricably linked to one another. Due to the forces arising during operation, this area of the gear pair is designed to be particularly stiff. A reduction gear is thereby formed.

Durch das Vorsehen von zwei mit dem Verstellteil direkt korrespondierenden Antriebszahnräder sind die Kontaktflächen der jeweiligen Verzahnungsflächen gegenüber den Verstellwerkzeugen nach dem Stand der Technik wesentlich erhöht. Deshalb ist die Krafteinleitung durch die beiden Antriebszahnräder wesentlich verbessert. Die insgesamt auftretenden Reibungsverluste sind insgesamt wesentlich verringert. Durch die vertikale Verzahnung an den Verstellflächen kann diese wesentlich länger ausgebildet sein kann als die horizontal ausgerichtete Verzahnung im Stand der Technik. Damit können auch größere Bodenunebenheiten mit dem Verstellwerkzeug ausgeglichen werden, so dass ein Sockelfuß und das erfindungsgemäße Verstellwerkzeug nicht höhengleich ausgerichtet sein müssen, so dass ein Sockelfuß auch tiefer auf einer Bodenfläche abgestützt sein kann als die Höhe, in der das Verstellwerkzeug angreift. Durch das durch die mehreren Zahnräder gebildete Getriebe ist sicherzustellen, dass die Umlenkung der Antriebskraft aus der horizontalen Richtung in die vertikale Richtung ausschließlich im Verstellwerkzeug selbst erfolgt, das mithin sehr steif auszubilden ist mit nicht lösbaren Verbindungen der Zahnräder. Mithin haben die beiden mit dem Verstellteil des Sockelfußes zusammenwirkende beiden Zahnräder lediglich den Antriebskontakt aufrecht zu erhalten, ohne dass große manuelle Bedienkräfte aufzubringen sind. Durch das Vorsehen von zwei Zahnrädern sind nicht nur die Kontaktflächen erhöht. Vielmehr können die Antriebskräfte auf das Verstellteil jeweils von zwei Seiten symmetrisch auf das Verstellteil aufgebracht werden, wodurch nur geringe Reibkräfte anfallen. Dadurch ist es möglich, mit nur geringem Kraftaufwand das Verstellwerkzeug zur Verstellung des Verstellteil eines Sockelfußes im Einhandbetrieb durchzuführen.By providing two drive gears that correspond directly to the adjustment part, the contact surfaces of the respective toothed surfaces are significantly increased compared to the adjustment tools according to the prior art. Therefore, the introduction of force through the two drive gears is significantly improved. The total friction losses that occur are significantly reduced overall. Due to the vertical toothing on the adjustment surfaces, this can be made significantly longer than the horizontally aligned toothing in the prior art. This means that even larger unevennesses in the floor can be compensated with the adjustment tool, so that a base foot and the adjustment tool according to the invention do not have to be aligned at the same height, so that a base foot can also be supported on a floor surface lower than the height at which the adjustment tool acts. The transmission formed by the several gears ensures that the driving force is deflected from the horizontal direction to the vertical direction exclusively in the adjustment tool itself, which therefore has to be made very stiff with non-detachable connections of the gears. Consequently, the two gear wheels interacting with the adjustment part of the base foot only have to maintain the drive contact, without the need to apply large manual operating forces. The provision of two gears not only increases the contact surfaces. Rather, the driving forces on the adjustment part can be applied symmetrically to the adjustment part from two sides, resulting in only low frictional forces. This makes it possible to carry out the adjusting tool for adjusting the adjusting part of a base foot in one-handed operation with only little effort.

Durch ein derartiges erfindungsgemäßes Verstellwerkzeug sind die Zahnräder des Kopfstückes des Verstellwerkzeuges autark nach entsprechender Einschaltung von einem elektromotorischen Antrieb anzutreiben und mithin für eine Verstellbewegung zu nutzen. Der Benutzer muss keinerlei Verdrehbewegung an einem Bedienteil mehr durchführen, sondern braucht nur einen Schalter zu betätigen für eine Drehrichtung, um die gewünschte Verstellung in die eine oder in die andere Richtung durchführen zu können. Damit läuft er auch nicht Gefahr, dass das Verstellwerkzeug durch geringe Bewegungen entkoppelt wird, da er zudem eine Hand frei hat, um beispielsweise auch eine Wasserwaage oder dgl. Geräte zu bedienen, um eine exakte Ausrichtung des aufzustellenden Möbels sicherzustellen.With such an adjustment tool according to the invention, the gear wheels of the head piece of the adjustment tool can be driven independently by an electric motor drive after they have been switched on accordingly and can therefore be used for an adjustment movement. The user no longer has to perform any twisting movement on an operating part, but only needs to actuate a switch for one direction of rotation in order to be able to carry out the desired adjustment in one direction or the other. He also does not run the risk of the adjusting tool being decoupled by small movements, since he also has one hand free to operate a spirit level or similar devices, for example, in order to ensure exact alignment of the piece of furniture to be set up.

In vorteilhafter Weise lässt sich der elektromotorische Antrieb so schalten, dass er in gegensinnige Bewegungen, also einmal im Uhrzeigersinn und einmal gegen den Uhrzeigersinn rotieren kann. Besonders bevorzugt wird, wenn die Verzahnung an dem Zahnrad und auch an dem Verstellteil gegenüber dem vorbekannten Verstellteil exakt um 90° anders ausgerichtet ist, also bei horizontaler Ausrichtung des Verstellwerkzeuges in senkrechter Richtung, womit die Verzahnung des Zahnrades sowohl bei dem Zahnrad des Kopfstückes als auch bei der Verzahnung am Verstellteil wesentlich länger ausgebildet werden als beim bekannten Stand der Technik kann mit dem Ergebnis, dass eine unbeabsichtigte Entkopplung von Verstellwerkzeug und Verstellteil während eines Bedienvorganges nahezu ausgeschlossen ist. Darüber hinaus ist eine größere Verzahnungskopplung zu realisieren. Darüber hinaus ist vorgesehen, dass nicht nur ein Zahnrad im Kopfstück vorgesehen ist, sondern zwei, die von einem gemeinsamen Zahnrad ihrerseits angetrieben werden, so dass eine wesentlich vergrößerte Zahnradkontaktfläche über beide Zahnräder am Verstellteil zur Verfügung gestellt werden kann. Das gemeinsame Zahnrad kann seinerseits über ein weiteres Zahnrad mit einem Schneckenrad (Rizelwelle) verbunden sein, das seinerseits von dem elektromotorischen Antrieb angetrieben wird. Insgesamt ist damit ein Verstellwerkzeug zur Verfügung gestellt, dessen Bedienung wesentlich vereinfacht ist.Advantageously, the electromotive drive can be switched in such a way that it can rotate in opposite directions, ie once clockwise and once counterclockwise. It is particularly preferred if the toothing on the gear wheel and also on the adjustment part is aligned exactly 90° differently from the previously known adjustment part, i.e. with a horizontal alignment of the adjustment tool in the vertical direction, whereby the toothing of the gear wheel is aligned both on the gear wheel of the head piece and the toothing on the adjustment part can be made much longer than in the known prior art, with the result that an unintentional decoupling of the adjustment tool and adjustment part during an operating process is almost impossible. In addition, a larger gear coupling is to be realized. In addition, it is provided that not only one gear is provided in the head piece, but two, which are in turn driven by a common gear, so that a significant increased gear contact area can be made available via both gears on the adjustment part. The common gear can in turn be connected via another gear to a worm wheel (pinion shaft), which in turn is driven by the electric motor drive. Overall, an adjustment tool is thus made available whose operation is significantly simplified.

Der elektromotorische Antrieb ist mit einer Mess- und Steuerungsvorrichtung verbunden, wobei die Mess- und Steuerungsvorrichtung den Neigungswinkel beispielsweise eines Möbels zur Horizontalen ermittelt, wobei über die Mess- und Steuerungsvorrichtung der elektromotorische Antrieb in Abhängigkeit des ermittelten Neigungswinkels gesteuert wird. Damit kann über diese Mess- und Steuereinrichtung eine Verstellung und damit ein Höhenausgleich auf automatische Weise erfolgen. Die entsprechenden Daten und Steuerbefehle können übermittelt werden über verschiedene Übermittlungsstrecken, z. B. über Funk, USB, Kabel oder dgl.. Die Justierung und damit Höhennivellierung erfordert in aller Regel nur eine geringe Zeit, wobei ein Nachjustieren durch eine Bedienperson nicht erforderlich ist, weil die exakte Höheneinstellung automatisch erfolgt. Zudem kann ein Sichtfenster vorgesehen sein, um Bedienanweisungen anzuzeigen, die die Bedienperson wahrnehmen kann.The electric motor drive is connected to a measuring and control device, the measuring and control device determining the angle of inclination, for example, of a piece of furniture to the horizontal, the measuring and control device controlling the electric motor drive depending on the determined angle of inclination. This means that an adjustment and thus a height adjustment can take place automatically via this measuring and control device. The corresponding data and control commands can be transmitted via various transmission paths, e.g. B. via radio, USB, cable or the like .. The adjustment and thus height leveling usually requires little time, with readjustment by an operator is not required because the exact height adjustment is done automatically. In addition, a viewing window can be provided to display operating instructions that the operator can perceive.

In der Zeichnung sind übereinstimmende Teile mit übereinstimmenden Bezugsziffern versehen. Allgemein mit 1 ist ein Verstellwerkzeug beziffert, das einen Handgriff 2, ein Kopfstück 4 sowie einen Aufnahmeraum 5 im Kopfstück aufweist. Wie näher Fig. 3 zu entnehmen ist, ist innerhalb des Kopfstückes 4 ein Aufnahmeraum 3 vorgesehen, in dem ein elektromotorischer Antrieb 6 angeordnet ist. Dieser wird von nicht dargestellten Batterien oder einem Akku mit elektrischer Energie versorgt.In the drawing, corresponding parts are provided with corresponding reference numbers. An adjustment tool is generally labeled 1 and has a handle 2, a head piece 4 and a receiving space 5 in the head piece. How closer 3 can be seen, there is a receiving space 3 inside the head piece 4 provided, in which an electric motor drive 6 is arranged. This is powered by batteries, not shown, or a rechargeable battery with electrical energy.

Das Verstellteil V (Fig. 4) ist - bezogen auf eine horizontale Bezugsebene - ausgerichtet mit einer vertikal ausgerichteten Verzahnung Z versehen. Diese Verzahnung Z kann von zwei Zahnrädern 7 und 8, die in die Aufnahme 5 (Fig. 3) ragen, angetrieben werden. Diese beiden Zahnräder 7 und 8 werden von einem weiteren Zahnrad 9 angetrieben. Dieses weitere Zahnrad 9 ist über eine Verbindung 10 mit einem weiteren Zahnrad 11 antriebsmäßig gekoppelt. Dieses weitere Zahnrad 11 wird von einem Schneckenrad 12 angetrieben, das wiederum von dem elektromotorischen Antrieb angetrieben wird. Des Weiteren ist ein Halterteil 13 in der Aufnahme 5 vorgesehen, das in dem gezeigten Ausführungsbeispiel als ortsfest positionierte Rolle ausgebildet ist. Zusätzlich ist ein weiteres Halterteil 14 vorgesehen, dass auch als Rolle ausgebildet ist, dass allerdings schwenkbar und von einer Feder 15 belastet angeordnet ist, so dass die Rolle 14 mithilfe der Feder 15 bei einem Ansetzen des Verstellwerkzeuges 1 auf ein Verstellteil V zunächst ausweichen kann und nach dem Aufsetzen dann mithilfe der Feder 15 gegen die Verzahnung Z gedrückt wird. Durch entsprechende Betätigung des Schalters 16 in die eine oder andere Richtung kann jetzt der elektromotorische Antrieb 6 eingeschaltet werden, um das Verstellteil V über das Gewinde G (Fig. 4) an einem Sockelfuß (nicht gezeigt) zu verstellen. Dies ist mit einfachem Bedienaufwand möglich.The adjustment part V ( 4 ) is - in relation to a horizontal reference plane - aligned with a vertically aligned toothing Z. This toothing Z can of two gears 7 and 8, which are in the recording 5 ( 3 ) protrude, be driven. These two gears 7 and 8 are driven by another gear 9 . This further gear wheel 9 is drivingly coupled to a further gear wheel 11 via a connection 10 . This additional gear 11 is driven by a worm wheel 12, which in turn is driven by the electric motor drive. Furthermore, a holder part 13 is provided in the receptacle 5, which is designed as a stationary positioned roller in the exemplary embodiment shown. In addition, another holder part 14 is provided, which is also designed as a roller, but which is pivotable and loaded by a spring 15, so that the roller 14 can initially give way with the help of the spring 15 when the adjustment tool 1 is applied to an adjustment part V and after it has been placed, it is then pressed against the toothing Z with the help of the spring 15. By appropriate actuation of the switch 16 in one direction or the other, the electric motor drive 6 can now be switched on in order to adjust the adjustment part V via the thread G ( 4 ) on a base foot (not shown). This is possible with a simple operating effort.

Fig. 5 zeigt das Verstellwerkzeug, das vom Grundsätzlichen her so aufgebaut ist, wie das Verstellwerkzeug, wie es in den Fig. 1 bis 4 beschrieben ist. Zusätzlich ist ein Schrank 20 gezeigt, der über einstellbare Füße 21 auf dem Boden eines Gebäudes abzustellen und über das Verstellwerkzeug 1 hinsichtlich des Höhenniveaus angepasst werden kann. Dazu ist die Steuermesseinrichtung 22 vorgesehen, die eine elektronische Waage beinhaltet. Diese kann über verschiedene Verbindungsstecker oder über sonstige Übertragungstechniken mit dem Verstellwerkzeug verbunden sein. In dem dargestellten Ausführungsbeispiel nach Fig. 5 soll dies über eine Funkstrecke erfolgen. Über eine Tastatur kann ein gewünschter Zustand eingestellt und auch angezeigt werden. Ebenfalls kann ein Display vorgesehen sein. Die elektronische Mess- und Steuereinheit steuert den elektrischen Antrieb des Verstellwerkzeuges über die Funkstrecke soweit, dass dieser Antrieb dann stoppt, wenn der exakte Höhenausgleich vorgenommen wurde und eine exakte horizontale Ausrichtung des Schrankes eingestellt ist. figure 5 shows the adjustment tool, which is basically constructed in such a way as the adjustment tool, as in the Figures 1 to 4 is described. Additionally is a cabinet 20 is shown, which can be placed on the floor of a building via adjustable feet 21 and adjusted via the adjustment tool 1 with regard to the height level. The control measuring device 22, which contains an electronic scale, is provided for this purpose. This can be connected to the adjusting tool via various connecting plugs or via other transmission technologies. In the illustrated embodiment after figure 5 this should be done via a radio link. A desired state can be set and also displayed via a keyboard. A display can also be provided. The electronic measuring and control unit controls the electric drive of the adjustment tool via the radio link to such an extent that this drive stops when the exact height adjustment has been made and an exact horizontal alignment of the cabinet has been set.

Das Ausführungsbeispiel nach Fig. 6 zeigt am Verstellwerkzeug 1 noch einmal eine Buchse 23 zur Aufnahme eines Steckers für eine Kabelverbindung zwischen der Steuer- und Messeinheit 22 und dem Verstellwerkzeug 1. Des Weiteren kann eine Verbindung zu einem PCT vorgesehen sein.The embodiment after 6 1 shows a socket 23 on the adjusting tool 1 for receiving a plug for a cable connection between the control and measuring unit 22 and the adjusting tool 1. A connection to a PCT can also be provided.
