Description

Die vorliegende Erfindung betrifft einen zahnärztlichen Behandlungsstuhl gemäß dem Oberbegriff des Anspruchs 1, bei dem eine Sitzbank gegenüber einer Basis des Behandlungsstuhls zwischen einer Grundposition und einer Höchstposition höhenverstellbar ist.The present invention relates to a dental treatment chair according to the preamble of claim 1, wherein a seat is height adjustable relative to a base of the treatment chair between a home position and a maximum position.

Zahnärztliche Behandlungsstühle sind in der Regel in mehreren Freiheitsgraden verstellbar, um den Patienten ergonomisch und behandlungsgerecht für die vorzunehmende Behandlung positionieren zu können. Ein klassischer Behandlungsstuhl besteht dabei aus einer höhenverstellbaren Sitzbank, an deren Ende eine gegenüber der Sitzbank verschwenkbare Rückenlehne angeordnet ist. An die Rückenlehne wiederum schließt sich üblicherweise ein Kopfpolster zur Lagerung des Patientenkopfes an. Die Einstellung der Position der Rückenlehne und des Kopfpolsters ist dabei in der Regel unabhängig von der Höheneinstellung der Sitzbank möglich. Darüber hinaus sind Behandlungsstühle bekannt, bei denen die Sitzbank nicht nur höhenverstellbar, sondern darüber hinaus auch noch leicht verschwenkbar ist, um eine so genannte Trendelenburg-Bewegung zu ermöglichen.Dental treatment chairs are usually adjustable in several degrees of freedom in order to position the patient ergonomically and treatment-appropriate for the treatment to be performed. A classic dental chair consists of a height-adjustable seat, at the end of a seat back against the seat pivoting backrest is arranged. The backrest, in turn, is usually followed by a head pad for supporting the patient's head. The adjustment of the position of the backrest and the head cushion is usually possible regardless of the height adjustment of the seat. In addition, treatment chairs are known in which the seat not only height adjustable, but also also slightly pivotable to allow a so-called Trendelenburg movement.

Die vorliegende Erfindung befasst sich insbesondere mit der Höhenverstellbarkeit der Sitzbank des Behandlungsstuhls. Hierzu sind verschiedene Antriebs- und Übertragungsmechanismen bekannt, welche eine Verstellung zwischen einer niedrigen Grundposition und einer Höchstposition ermöglichen. Der Antrieb und der Hubmechanismus können dabei beispielsweise unterhalb der Sitzbank angeordnet sein, es sind allerdings auch zahnärztliche Behandlungsplätze bekannt, bei denen die zentrale Versorgungseinrichtung durch eine quaderförmige Säule gebildet ist, wobei der Patientenstuhl dann seitlich der Säule angeordnet und mit einem sich in der Säule befindenden Antrieb gekoppelt ist.The present invention is particularly concerned with the height adjustability of the bench of the treatment chair. For this purpose, various drive and transmission mechanisms are known which allow adjustment between a low home position and a maximum position. The drive and the lifting mechanism can be arranged for example below the seat, but there are also dental treatment stations are known in which the central supply device is formed by a rectangular column, the patient chair then arranged laterally of the column and with a located in the column Drive is coupled.

Die Höhenverstellbarkeit des Behandlungsstuhls soll sich dabei in einem Bereich bewegen, der eine für den behandelnden Zahnarzt optimale bzw. angenehme Behandlung ermöglicht. Da Zahnärzte unterschiedliche Größen aufweisen, bedeutet dies, dass auch die Höhenverstellbarkeit innerhalb bestimmter Grenzen liegen sollte, die von der Größe des Arztes abhängig sind. Des Weiteren sollte der Bewegungsspielraum davon abhängig sein, ob der Zahnarzt Behandlungen bevorzugt stehend oder sitzend durchführt. Schließlich hängt die Anordnung des Behandlungsstuhls gegenüber der säulenartigen Basis auch davon ab, ob es sich bei dem Zahnarzt um einen Links- oder Rechtshänder handelt.The height adjustment of the treatment chair should move in a range that allows optimal or pleasant treatment for the treating dentist. Since dentists have different sizes, this means that the height adjustment should also be within certain limits, which are dependent on the size of the doctor. Furthermore, the range of motion should be dependent on whether the dentist prefers treatments performed standing or sitting. Finally, the arrangement of the Treatment chair opposite the columnar base also on whether the dentist is a left or right handed person.

Um die Ausgestaltung derartiger Behandlungsstühle jeweils an die Wünsche eines Zahnarztes individuell anpassen zu können, waren bisher aufwändige Maßnahmen erforderlich. Diese waren mit einem verhältnismäßig hohen Kostenaufwand verbunden, der im Hinblick darauf, dass der Patientenstuhl nach einer endgültigen Montage nur noch lediglich in einem bestimmten, auf den Zahnarzt abgestimmten Bereich höhenverstellbar sein muss, nicht gerechtfertigt war.In order to be able to individually adapt the design of such treatment chairs to the wishes of a dentist, elaborate measures have hitherto been necessary. These were associated with a relatively high cost, which was not justified in view of the fact that the patient chair after a final assembly only in a certain, adapted to the dentist area must be adjustable in height.

Aus der GB 1 203 329 ist ein zahnärztlicher Behandlungsstuhl mit einer säulenartigen Basis und einer seitlich davon höhenverstellbar angeordneten Sitzbank bekannt. In der Basis ist ein Antrieb zur Höhenverstellung der Sitzbank angeordnet. Die Sitzbank ist mit dem Antrieb über einen Übertragungsmechanismus gekoppelt, der einen vertikal verfahrbaren Trägerarm aufweist. Die Angriffspunkte des Trägerarms an dem Antrieb und an der Sitzbank sind unterschiedlich hoch.From the GB 1 203 329 is a dental treatment chair with a columnar base and a laterally arranged height adjustable seat known. In the base of a drive for height adjustment of the seat is arranged. The seat is coupled to the drive via a transmission mechanism having a vertically movable support arm. The points of attack of the carrier arm on the drive and on the seat are of different heights.

Der vorliegenden Erfindung liegt deshalb die Aufgabe zu Grunde, eine neuartige und insbesondere kostengünstige Möglichkeit anzugeben, die Höhenverstellbarkeit und Anordnung eines zahnärztlichen Behandlungsstuhls in einfacher Weise auf die Bedürfnisse eines Zahnarztes abzustimmen.The present invention is therefore based on the object to provide a novel and particularly cost-effective way to tailor the height adjustment and arrangement of a dental treatment chair in a simple manner to the needs of a dentist.

Die Aufgabe wird durch einen zahnärztlichen Behandlungsstuhl, welcher die Merkmale des Anspruchs 1 aufweist, gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.The object is achieved by a dental treatment chair, which has the features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.

Die erfindungsgemäße Lösung beruht auf der Idee, die Kopplung zwischen Sitzbank des Behandlungsstuhls und Antrieb mit einem vertikal verfahrbaren Trägerarm auszugestalten, an dessen dem Antrieb abgewandten Ende die Sitzbank befestigt ist, wobei der Trägerarm derart geneigt ausgebildet ist, dass die Angriffspunkte des Trägerarms an dem Antrieb und der Sitzbank in vertikaler Richtung verschieden sind. Diese Lösung ermöglicht es, durch die Verwendung unterschiedlich gestalteter, vorzugsweise Z-artiger Trägerarme die Höhenverstellbarkeit und Anordnung der Sitzbank in einfacher Weise an die Bedürfnisse eines Zahnarztes anzupassen. Insbesondere ist im wesentlichen der Einsatz zweier verschiedener Trägerarme ausreichend, welche wahlweise genutzt werden können, wobei bei einem der beiden Trägerarme der Angriffspunkt an dem Antrieb oberhalb des Angriffspunkts an der Sitzbank liegt und bei dem anderen Trägerarm der Angriffspunkt an dem Antrieb unterhalb des Angriffspunkts an der Sitzbank liegt. Je nachdem, ob der Zahnarzt bevorzugt Behandlungen im Stehen oder im Sitzen durchführt, kann der Patientenstuhl dann mit dem entsprechenden Trägerarm an den Antrieb gekoppelt werden. Bei einer Anlenkung der Trägerarme in entgegengesetzter Richtung könnte wiederum die Sitzbank in einfacher Weise von einem klassischen Rechtshänderbetrieb auf einen Linkshänderbetrieb umgestellt werden. Auch hier können beide Trägerarme wahlweise eingesetzt werden, um den Spielraum der Höhenverstellbarkeit an die bevorzugte Arbeitsweise des Zahnarztes anzupassen.The solution according to the invention is based on the idea of designing the coupling between the seat of the treatment chair and drive with a vertically movable support arm, at the end facing away from the drive, the seat is fixed, wherein the support arm is formed inclined so that the points of application of the support arm to the drive and the seat are different in the vertical direction. This solution makes it possible to adjust the height adjustment and arrangement of the seat in a simple manner to the needs of a dentist by using differently shaped, preferably Z-like support arms. In particular, the use of two different support arms is sufficient, which can optionally be used, wherein in one of the two support arms of the attack on the drive above the point of attack on the bench and the other support arm of the attack on the drive below the point of attack on the Bench is located. Depending on whether the dentist preferably performs treatments while standing or sitting, the patient chair can then be coupled with the corresponding support arm to the drive. In an articulation of the support arms in the opposite direction, in turn, the seat could be converted in a simple manner from a classic right-handed operation to a left-handed operation. Again, both support arms can optionally be used to adjust the scope of height adjustment to the preferred operation of the dentist.

Erfindungsgemäß wird also ein zahnärztlicher Behandlungsstuhl bereit gestellt, der eine säulenartige Basis, eine seitlich von der Basis angeordnete und gegenüber dieser zwischen einer Grundposition und einer Höchstposition höhenverstellbare Sitzbank, einen in der Basis angeordneten Antrieb zur Höhenverstellung der Sitzbank sowie einen die Sitzbank mit dem Antrieb koppelnden Übertragungsmechanismus aufweist, der einen vertikal verfahrbaren Trägerarm umfasst, an dessen dem Antrieb abgewandten Ende die Sitzbank befestigt ist, wobei erfindungsgemäß der Trägerarm derart geneigt ausgebildet ist, dass die Angriffspunkte des Trägerarms an dem Antrieb und der Sitzbank in vertikaler Richtung unterschiedlich sind.According to the invention, therefore, a dental treatment chair is provided which has a columnar base, a seat arranged laterally from the base and height-adjustable relative thereto between a home position and a maximum position, a drive arranged in the base for height adjustment of the seat, and a seat coupled to the drive Transmission mechanism comprising a vertically movable support arm, at the end facing away from the drive, the seat is fixed, according to the invention, the support arm is formed inclined so that the points of application of the support arm on the drive and the seat are different in the vertical direction.

Der bzw. die Trägerarme sind vorzugsweise rohrförmig ausgebildet, wobei für den Fall, dass zwei verschiedene Trägerarme wahlweise bereitgestellt werden, diese auch unterschiedliche horizontale Längen aufweisen können. Hierdurch kann nochmals die Anordnung der Sitzbank in besonderer Weise an die bevorzugte Arbeitsweise des Arztes angepasst werden.The or the support arms are preferably tubular, wherein in the event that two different support arms are selectively provided, they may also have different horizontal lengths. As a result, once again the arrangement of the seat can be adapted in a special way to the preferred mode of operation of the physician.

Als Antrieb ist vorzugsweise ein in der Basis angeordneter Spindelantrieb vorgesehen, der eine vertikal ausgerichtete Antriebsspindel aufweist, welche in geeigneter Weise mit dem Träger gekoppelt ist. Auch der Einsatz eines pneumatischen oder hydraulischen Antriebs wäre denkbar.As drive, a spindle drive arranged in the base is preferably provided, which has a vertically oriented drive spindle, which is suitably coupled to the carrier. The use of a pneumatic or hydraulic drive would be conceivable.

Der in Figur 1 allgemein mit dem Bezugszeichen 10 versehene erfindungsgemäße Behandlungsstuhl ist Bestandteil eines zahnärztlichen Arbeitsplatzes 1. Dieser Arbeitsplatz 1 weist als zentrales Element 2 eine säulenartige Versorgungseinrichtung auf, welche der Halterung, Ansteuerung und Versorgung der entsprechenden Komponenten des Behandlungsplatzes 1 dient. Hierunter fallen beispielsweise ein erster Servicetisch 4, der über einen Schwenkarm 3 mit der säulenartigen Basis 2 verbunden ist. Dieser Servicetisch 4 wird primär von dem behandelnden Zahnarzt genutzt und dient der Lagerung beziehungsweise Ansteuerung zahnärztlicher Behandlungsinstrumente wie zum Beispiel Bohrer, Zahnsteinentferner und dergleichen. Über mehrere Bedienelemente, die an dem Servicetisch 4 ausgebildet sind, kann eine Steuerung der entsprechenden Komponenten des Behandlungsplatzes 1 vorgenommen werden. Beispielsweise können diese Eingabeelemente dazu genutzt werden, den Behandlungsstuhl 10 zu verstellen.The in FIG. 1 This treatment chair according to the invention generally provided with the reference numeral 10 is part of a dental workstation 1. This workstation 1 has as a central element 2 a columnar supply device which serves to hold, control and supply the corresponding components of the treatment station 1. This includes, for example, a first service table 4, which is connected to the columnar base 2 via a pivoting arm 3. This service table 4 is primarily used by the treating dentist and is used for storage or control of dental treatment instruments such as drills, scaler and the like. Via a plurality of operating elements, which are formed on the service table 4, a control of the corresponding components of the treatment station 1 can be carried out. For example, these input elements can be used to adjust the treatment chair 10.

Des Weiteren ist an der Basis 2 über einen zweiten Schwenkarm 5 ein Helferinnenelement 6 befestigt. Dieses vorzugsweise von einer Hilfskraft genutzte Element 6 dient ebenfalls der Lagerung und Ansteuerung einzelner Instrumente wie Sauger oder so genannter Spritzhandstücke. Ferner kann auch die Steuerung des Patiententeils 7, welches eine Speischale sowie eine Wasserversorgung umfasst, über dieses Helferinnenelement 6 vorgenommen werden. In dieser Hinsicht entspricht der in Figur 1 dargestellte zahnärztliche Behandlungsplatz 1 klassischen dentalmedizinischen Behandlungsplätzen.Furthermore, a helper inner element 6 is attached to the base 2 via a second pivot arm 5. This preferably used by an assistant element 6 also serves to store and control individual instruments such as suckers or so-called spray handpieces. Furthermore, the control of the patient part 7, which includes a spittoon as well as a water supply, can be made via this helper inner element 6. In this regard, the equivalent in FIG. 1 illustrated dental treatment center 1 classic dental treatment stations.

Die Zentralsäule 2 dient zusätzlich auch der Halterung des Behandlungsstuhls 10, der zunächst eine Sitzbank 11 aufweist. Am rückseitigen Ende der Sitzbank 11 sind ferner eine gegenüber dieser verschwenkbare Rückenlehne 12 sowie sich daran anschließend eine Kopfstütze 13 angeordnet. Beide Komponenten - Rückenlehne 12 und Kopfstütze 13 - können unabhängig voneinander in gewünschter Weise verstellt werden, um diese an den Patienten, insbesondere dessen Größe, sowie die Arbeitsweise des Zahnarztes anzupassen. Die Verstellmöglichkeiten für die Rückenlehne 12 und die Kopfstütze 13 sind allerdings nicht Gegenstand der vorliegenden Erfindung und sollen dementsprechend nachfolgend nicht näher erläutert werden.The central column 2 additionally serves to hold the treatment chair 10, which initially has a seat 11. At the rear end of the seat 11 are also a relative to this pivotable backrest 12 and then a headrest 13 is arranged thereafter. Both components - backrest 12 and headrest 13 - can be adjusted independently of one another in the desired manner, in order to adapt them to the patient, in particular its size, as well as the operation of the dentist. However, the adjustment of the backrest 12 and the headrest 13 are not the subject of the present invention and accordingly shall not be explained in detail below.

Die vorliegende Erfindung betrifft wie bereits erwähnt stattdessen die Höhenverstellbarkeit des Behandlungsstuhls 10. Eine erste Besonderheit besteht hierbei darin, dass der hierzu erforderliche Antrieb nicht - wie bislang überwiegend der Fall - unterhalb der Sitzbank 11 sondern stattdessen in der als Basis dienenden Versorgungseinheit 2 angeordnet ist. Unter der Sitzbank 11 verbleibt somit ein Feiraum, der zur Anbringung einer Trittplatte 14 genutzt werden kann.As already mentioned, the present invention relates instead to the height adjustability of the treatment chair 10. A first special feature is that the drive required for this purpose is not arranged below the seat 11, as was previously the case, but instead in the supply unit 2 serving as a base. Thus, under the seat 11 there remains a free space which can be used to attach a footboard 14.

Der innerhalb der Basis 2 angeordnete und in Figur 1 nicht näher dargestellte Antrieb dient dementsprechend dazu, ein vertikales Verfahren der Sitzbank 11 zu ermöglichen. Hierbei sollte die Sitzbank 11 und damit der Patientenstuhl 10 in einem Bereich verstellt werden können, der eine optimierte Arbeitsweise für den Zahnarzt ermöglicht. Dabei ist zu berücksichtigen, dass sowohl eine Behandlung im Stehen als auch im Sitzen denkbar ist, wobei unterschiedliche Präferenzen auf Seiten des Zahnarzts bestehen können. Der Bereich, in dem der Patientenstuhl 10 höhenverstellt werden kann, sollte also an die Bedürfnisse bzw. Wünsche des Zahnarztes angepasst werden. In gleicher Weise sollte auch eine Anordnung des Behandlungsstuhls 10 auf der gegenüberliegenden Seite der Basis 2 ermöglicht sein, um eine Nutzung auch durch Linkshänder zu ermöglichen. Eine Lösung, welche in einfacher Weise eine Anpassung an die Bedürfnisse des Zahnarztes ermöglicht und kostengünstig realisiert werden kann, soll anhand der nachfolgenden Figuren nunmehr erläutert werden.The arranged within the base 2 and in FIG. 1 Drive not shown serves accordingly to allow a vertical movement of the seat 11. Here, the seat 11 and thus the patient chair 10 should be able to be adjusted in a range that allows optimized operation for the dentist. It should be noted that both a treatment while standing and sitting is conceivable, with different preferences may exist on the part of the dentist. The area in which the patient chair 10 can be adjusted in height, should therefore be adapted to the needs or wishes of the dentist. In the same way, an arrangement of the treatment chair 10 on the opposite side of the base 2 should be made possible to allow use by left-handers. A solution which allows a simple adaptation to the needs of the dentist and can be realized inexpensively, will now be explained with reference to the following figures.

Die erfindungsgemäße Lösung beruht darauf, einen speziellen Übertragungsmechanismus zur Kraftübertragung für die Höhenverstellbarkeit des Behandlungsstuhl einzusetzen, der aufgrund seiner Ausgestaltung ein einfaches Anpassen des Verstellbereichs an die individuellen Wünsche des Zahnarztes ermöglicht. Die Figuren 2 und 3 zeigen hierzu die Details der erfindungsgemäßen Ankopplung des Behandlungsstuhls an den innerhalb der säulenartigen Basis befindlichen Antrieb.The solution according to the invention is based on using a special transmission mechanism for power transmission for the height adjustment of the treatment chair, which, due to its design, enables a simple adaptation of the adjustment range to the individual wishes of the dentist. The FIGS. 2 and 3 show the details of the coupling of the treatment chair according to the invention to the drive located within the columnar base.

Der Antrieb 20 ist in dem dargestellten Ausführungsbeispiel als Spindelantrieb 20 ausgeführt und weist hierzu einen Motor 21 auf, der mit einer vertikal ausgerichteten Antriebsspindel 22 gekoppelt ist. Mit der Antriebsspindel 22 ist ferner ein Führungsteil 24 gekoppelt, welches an einer innerhalb der Basis angeordneten Führungssäule 23 vertikal verschiebbar gelagert ist. Hierzu wirkt das Führungsteil 24 mit entsprechenden, an den Seitenwänden der Führungssäule 23 ausgebildeten Führungsschienen 25 zusammen. Die Laufflächen werden in diesem Fall durch Stahlbänder gebildet. Durch einen entsprechenden Betrieb des Motors 21 wird dann das Führungsteil 24 in gewünschter Weise vertikal entlang der Säule 23 verfahren.The drive 20 is designed in the illustrated embodiment as a spindle drive 20 and has for this purpose a motor 21 which is coupled to a vertically oriented drive spindle 22. With the drive spindle 22, a guide member 24 is further coupled, which is mounted vertically displaceably on a guide column 23 arranged within the base. For this purpose, the guide member 24 cooperates with corresponding, formed on the side walls of the guide column 23 guide rails 25 together. The treads are formed in this case by steel bands. By a corresponding operation of the motor 21, the guide member 24 is then moved vertically along the column 23 in the desired manner.

Alternativ zu dem dargestellten Spindelantrieb könnte beispielsweise auch ein pneumatischer oder hydraulischer Antrieb eingesetzt werden.As an alternative to the spindle drive shown, for example, a pneumatic or hydraulic drive could be used.

Die Ankopplung des Behandlungsstuhls 10 an den Antrieb erfolgt nun über einen Trägerarm 30, der mit seinem einen Ende mit dem Führungsteil 24 und mit seinem anderen Ende mit dem Patientenstuhl 10 beziehungsweise der Sitzbank 11 verbunden ist. Die Ausgestaltung dieses Trägerarms 30 kann näher den Figuren 4a und 4b entnommen werden.The coupling of the treatment chair 10 to the drive is now via a support arm 30 which is connected at one end to the guide member 24 and at its other end to the patient chair 10 and the seat 11, respectively. The design of this support arm 30 can closer to FIGS. 4a and 4b be removed.

Wie in diesen beiden Figuren gezeigt, ist der Trägerarm 30 Z-artig bzw. geneigt abgewinkelt ausgebildet. Er weist hierzu zunächst ein erstes Ende 31 in Form eines Befestigungsflansches auf, der zur Befestigung an dem Führungsteil 24 vorgesehen ist. Ein zweites Ende 32 wiederum dient der Befestigung an der Sitzbank bzw. einem unterhalb der Sitzbank befindlichen Trägerteil. Beide Enden 31, 32 sind hierbei über einen Verbindungsabschnitt 33 verbunden, der insbesondere derart ausgeführt ist, dass bei horizontaler Anordnung des Trägerarms 30 insgesamt das zweite, zur Befestigung an dem Patientenstuhl 10 vorgesehene Ende 32 unterhalb des ersten Endes 31 liegt. Mit anderen Worten, der Angriffspunkt des Trägerarms 30 an dem Antrieb liegt oberhalb des Angriffspunkts an der Sitzbank 11 des Behandlungsstuhl, wie den Darstellungen in den Figuren 2 und 3 entnommen werden kann.As shown in these two figures, the support arm 30 is formed Z-like or inclined angled. For this purpose, it first has a first end 31 in the form of a fastening flange, which is provided for attachment to the guide part 24. A second end 32 in turn serves the attachment to the seat or a support member located below the seat. Both ends 31, 32 are in this case connected via a connecting portion 33, which is designed in particular such that in the horizontal arrangement of the support arm 30 a total of the second, provided for attachment to the patient chair 10 end 32 is below the first end 31. In other words, the point of application of the support arm 30 on the drive is above the point of attack on the bench 11 of the treatment chair, as the representations in the FIGS. 2 and 3 can be removed.

Alternativ zu dem in den Figuren 4a und 4b dargestellten Trägerarm 30 könnte nunmehr allerdings auch ein zweiter Trägerarm zur Befestigung des Behandlungsstuhls 10 an dem Antrieb 20 genutzt werden, der in den Figuren 5a und 5b dargestellt und mit den Bezugszeichen 40 versehen ist. Auch dieser alternative Trägerarm 40 weist ein erstes Ende 41 zur Befestigung an dem Führungsteil 24 und ein zweites Ende 42 zur Befestigung an dem Patientenstuhl 10 auf, wobei beide Enden 41, 42 wiederum über ein Verbindungsteil 43 abgewinkelt miteinander verbunden sind. Ebenso wie der erste Trägerarm 30 ist auch der zweite Trägerarm 40 rohrförmig ausgebildet und beispielsweise durch ein Gussteil gebildet.Alternatively to that in the FIGS. 4a and 4b However, now shown, a second support arm for attaching the treatment chair 10 could be used on the drive 20, which in the FIGS. 5a and 5b is shown and provided with the reference numeral 40. Also, this alternative support arm 40 has a first end 41 for attachment to the guide member 24 and a second end 42 for attachment to the patient chair 10, both ends 41, 42 are in turn connected via an interconnecting part 43 angled together. Like the first carrier arm 30, the second carrier arm 40 is tubular and formed, for example, by a casting.

Der Unterschied zwischen beiden Trägerarmen 30, 40 besteht nunmehr darin, dass die Neigung des Verbindungsabschnitts 43 zwischen dem ersten und zweiten Ende 41, 42 des zweiten Trägerarms 40 entgegengesetzt zu dem Verbindungsabschnitt 33 des ersten Trägerarms 30 ist. Wie insbesondere der Darstellung in Figur 5b entnommen werden kann, bedeutet dies, dass der Angriffspunkt an dem Patientenstuhl 10 nunmehr oberhalb des Angriffspunkts an dem Antrieb liegt. Die sich hieraus ergebenden Konsequenzen können den Figuren 6 und 7 entnommen werden, welche jeweils die Anordnung der beiden Trägerarme 30, 40 an dem Antrieb 20 zeigen, wobei sich das Führungsteil 24 jeweils in der untersten möglichen Position an der Führungssäule 23 befindet.The difference between the two support arms 30, 40 is now that the inclination of the connecting portion 43 between the first and second ends 41, 42 of the second support arm 40 is opposite to the connecting portion 33 of the first support arm 30. As in particular the representation in FIG. 5b can be removed, this means that the point of attack on the patient chair 10 is now above the point of attack on the drive. The resulting consequences can be the FIGS. 6 and 7 are removed, which respectively show the arrangement of the two support arms 30, 40 on the drive 20, wherein the Guide member 24 is located in each case in the lowest possible position on the guide column 23.

Deutlich ist erkennbar, dass das zweite Ende 32 bzw. 42 des Trägerarms 30 bzw. 40, welches der Halterung des Behandlungsstuhls 10 dient, bei dem ersten Trägerarm 30 niedriger angeordnet ist als bei dem zweiten Trägerarm 40. Dies bedeutet, dass der Spielraum zur Verstellung des Behandlungsstuhls 10 im Rahmen der Hubbewegung unterschiedlich ist. Während mit Hilfe des ersten Trägerarms 30 der Patientenstuhl 10 zwischen einer besonders niedrigen und einer vorgegebenen Maximalposition verstellbar ist, kann mit Hilfe des zweiten Trägerarms 40 der Patientenstuhl von einer etwas höheren Ausgangsposition, die in Figur 7 dargestellt ist, bis zu einer maximalen Höhe verstellt werden. Dementsprechend wird der erste Trägerarm 30 vorzugsweise in solchen Fällen eingesetzt, bei denen der Zahnarzt eine Behandlung im Sitzen bevorzugt. Der Trägerarm 40 wiederum dient insbesondere zur Realisierung einer Verstellmöglichkeit, die für einen bevorzugt stehenden Zahnarzt von Vorteil ist.It can clearly be seen that the second end 32 or 42 of the support arm 30 or 40, which serves to hold the treatment chair 10, is arranged lower at the first support arm 30 than at the second support arm 40. This means that the clearance for adjustment of the treatment chair 10 is different within the scope of the lifting movement. While with the aid of the first support arm 30 of the patient chair 10 is adjustable between a particularly low and a predetermined maximum position, with the help of the second support arm 40 of the patient chair from a slightly higher starting position, the FIG. 7 is shown to be adjusted to a maximum height. Accordingly, the first support arm 30 is preferably used in those cases where the dentist prefers a sitting treatment. The support arm 40 in turn serves in particular for the realization of an adjustment, which is advantageous for a preferred dentist.

Durch die erfindungsgemäße Ausgestaltung des Antriebs beziehungsweise Übertragungsmechanismussees zur Höhenverstellbarkeit des Behandlungsstuhls kann also der Verstellbereich durch die Wahl des geeigneten Trägerarms in einfacher Weise an die Bedürfnisse eines Zahnarztes angepasst werden. Hierbei besteht ferner auch die Möglichkeit, die horizontale Länge des Verbindungsabschnitts 33 beziehungsweise 34 in entsprechender Weise zu wählen, um die Anordnung des Behandlungsstuhls 10 in horizontaler Richtung einzustellen.Due to the inventive design of the drive or transmission mechanism lake for height adjustment of the treatment chair so the adjustment can be adjusted by the choice of the appropriate support arm in a simple manner to the needs of a dentist. In this case, it is also possible to choose the horizontal length of the connecting portion 33 or 34 in a corresponding manner to adjust the arrangement of the treatment chair 10 in the horizontal direction.

Ein weiterer Vorteil der erfindungsgemäßen Lösung besteht auch darin, dass der Patientenstuhl in einfacher Weise derart konfiguriert werden kann, dass er für die Nutzung im Linkshänderbetrieb geeignet ist. Hierzu ist im Wesentlichen lediglich eine vertauschte Anordnung des Trägerarms beziehungsweise des Führungsteils 24 an der Führungssäule 23 erforderlich. Dabei ist ersichtlich, dass wiederum durch die Nutzung der beiden in den Figuren 4a bis 5b dargestellten Trägerarme unterschiedliche Verstellhöhen beziehungsweise Verstellbereiche für den Patientenstuhl 10 realisiert werden können. Da in diesem Fall ein verdrehtes Befestigen der Trägerarme erforderlich ist, bedeutet dies, dass nunmehr die Nutzung des ersten Trägerarms 30 zur Realisierung eine Verstellbereichs für größere Höhen erforderlich ist, während hingegen der zweite Trägerarm 40 niedrigere Verstellhöhen ermöglicht und damit insbesondere für ein Nutzung im Sitzen geeignet ist.A further advantage of the solution according to the invention is also that the patient chair can be configured in a simple manner so that it is suitable for use in left-handed operation. For this purpose, essentially only a reversed arrangement of the support arm or of the guide part 24 on the guide column 23 is required. It can be seen that again by the use of the two in the FIGS. 4a to 5b carrier arms shown different adjustment heights or adjustment ranges for the patient chair 10 can be realized. Since in this case a twisted fastening of the support arms is required, this means that now the use of the first support arm 30 for realizing an adjustment for larger heights is required, while the second support arm 40 allows lower adjustment heights and thus in particular for use in a sitting position suitable is.

Insgesamt gesehen können also die unterschiedlichen Verstellmöglichkeiten für den Behandlungsstuhl sowie die Anordnung auf der gewünschten Seite der zentralen Versorgungseinrichtung des Versorgungsplatzes durch die zur Verfügungstellung lediglich zweier verschiedener Trägerarme zur realisiert werden. Die erfindungsgemäße Lösung zeichnet sich dementsprechend durch ihre Einfachheit und insbesondere auch dadurch aus, dass sie kostengünstig zu realisieren ist.Overall, therefore, the different adjustment options for the treatment chair and the arrangement on the desired side of the central Supply device of the supply station by the provision of only two different support arms to be realized. The solution according to the invention is accordingly distinguished by its simplicity and, in particular, by the fact that it can be realized inexpensively.

Abschließend ist in den Figuren 8 bis 10 eine alternative Ausführungsform zur Lagerung und Führung der Trägerarme gezeigt. Bei dieser Ausführungsform, bei der zu dem ersten Ausführungsbeispiel der vorherigen Figuren identische Elemente mit dem gleichen Bezugszeichen versehen sind, kommt wiederum ein Spindelantrieb mit einem Motor 21 und einer Antriebsspindel 22 zum Einsatz. Die Führung des Trägerarms 30 entlang der Säule 23 erfolgt nunmehr allerdings über eine sog. Kugelumlaufführung. Hierzu ist an der dem Trägerarm 30 zugewandten Seite der Säule 23 eine Führungsschiene 50 vorgesehen, auf der ein Schlitten 51 bewegbar gelagert ist, wobei der Schlitten 51 ferner auch mit der Antriebsspindel 22 gekoppelt und mit dem Trägerarm 30 verbunden ist. Eine reibungsfrei Führung des Schlittens 51 in vertikaler Richtung wird dadurch erzielt, dass innerhalb des Schlittens 51 Kugeln gelagert sind, welche entlang von Laufflächen abrollen können, die an Seitenflächen der Führungsschiene 50 ausgebildet sind. Hinsichtlich der weiteren Eigenschaften dieses zweiten Ausführungsbeispiels kann auf die Ausführungen zu dem ersten Ausführungsbeispiel verwiesen werden. Auch bei dieser Variante können die Verstellmöglichkeiten für den Behandlungsstuhl in einfacher Weise an die entsprechenden Wünsche des Benutzers individuell angepasst werden.Finally, in the FIGS. 8 to 10 an alternative embodiment for the storage and management of the support arms shown. In this embodiment, in which identical elements to the first embodiment of the previous figures are provided with the same reference numeral, again a spindle drive with a motor 21 and a drive spindle 22 is used. However, the guide of the support arm 30 along the column 23 now takes place via a so-called ball recirculation guide. For this purpose, a guide rail 50 is provided on the side facing the support arm 30 side of the column 23, on which a carriage 51 is movably mounted, wherein the carriage 51 is further coupled to the drive spindle 22 and connected to the support arm 30. A friction-free guidance of the carriage 51 in the vertical direction is achieved in that within the carriage 51 balls are mounted, which can roll along running surfaces, which are formed on side surfaces of the guide rail 50. With regard to the further properties of this second embodiment, reference may be made to the comments on the first embodiment. In this variant too, the adjustment possibilities for the treatment chair can be adapted in a simple manner to the corresponding wishes of the user.
