Description

Die Erfindung bezieht sich auf ein zahnärztliches Gerät mit an Versorgungsleitungen gebundenen Handstücken, die in ihrer Nichtgebrauchslage in muldenförmigen Ablagevorrichtungen ablegbar sind und deren Versorgungsleitungen mittels Stützglieder in einer schräg aufwärts und von der Bedienstelle weg gerichteten Position gehalten werden, wobei die Stützglieder jeweils um eine horizontale Achslagerung schwenkbar und mit einer Rückstellkraft belastet angeordnet sind, um die Versorgungsleitung nach Ablage des Handstückes wieder in seine Nichtgebrauchslage zurückzuführen.The invention relates to a dental device with handpieces bound to supply lines, which in their non-use position can be stored in trough-shaped storage devices and whose supply lines are held in an obliquely upward direction and away from the operating point by means of support members, the support members in each case about a horizontal axis bearing are arranged pivotably and loaded with a restoring force in order to return the supply line to its non-use position after the handpiece has been put down.

Solche, häufig als "Peitschengeräte" bezeichneten Geräte sind beispielsweise aus DE-16 28 080, DE-23 34 054 unde DE-20 46 989 bekannt. Während bei den in den erstgenannten beiden Druckschriften offenbarten Geräten Handstück- "Peitschen" mit Stützgliedem in Form von federnden Elementen vorgesehen sind, sind bei dem in der zuletzt genannten Druckschrift beschriebenen Gerät die Versorgungsleitungen jeweils in Hohlprofilstangen geführt, die wiederum in zylindrischen Schwenklagem axial aneinandergereiht montiert sind. Zum Zwecke einer Nachrüstung, eines Austausches oder einer Umstellung der Reihenfolge der aneinandergereihten einzelnen "Peitschen" können die einzelnen Stützglieder zusammen mit den Schwenklagem von der gemeinsamen Schwenklagerachse abgezogen werden. Das Wechseln einer solchen "Peitsche" ist jedoch verhältnismäßig aufwendig und kann in der Regel nur von einem Servicefachmann vorgenommen werden.Such devices, often referred to as "whip devices", are known, for example, from DE-16 28 080, DE-23 34 054 and DE-20 46 989. While handpiece "whips" with support members in the form of resilient elements are provided in the devices disclosed in the first two documents, the supply lines are each guided in hollow profile rods in the device described in the last-mentioned document, which in turn are mounted axially in a row in cylindrical pivot positions are. For the purpose of retrofitting, exchanging or changing the order of the individual "lashes" lined up, the individual support members, together with the pivot bearings, can be removed from the common pivot bearing axis. However, changing such a "whip" is relatively complex and can generally only be carried out by a service specialist.

Der im Anspruch 1 angegebenen Erfindung liegt die Aufgabe zugrunde, demgegenüber ein verbessertes Gerät der eingangs genannten Gattung anzugeben, bei dem insbesondere die Bedien-und Servicefreundlichkeit verbessert ist.The object of the invention specified in claim 1, on the other hand, is to provide an improved device of the type mentioned at the outset, in which, in particular, the ease of use and service is improved.

Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind in den Unteransprüchen enthalten.Advantageous refinements and developments of the invention are contained in the subclaims.

Dadurch, daß sowohl die Versorgungsleitungen als auch das Stützglied einer jeden Handstück-Peitsche am Gerät betriebsmäßig, d.h. ohne Zuhilfenahme von Werkzeugen, lösbar gehaltert sind, ist jederzeit ein schneller Wechsel auch von einem Nichtfachmann möglich. Wenn auch noch die Versorgungsleitung am Stützglied durch betriebsmäßig zu lösende Halterungs-bzw. Führungsglieder abgestützt ist, so ist auch ein Wechsel lediglich der Versorgungsleitung möglich, ohne daß hierzu das zugehörige Stützglied abgenommen zu werden braucht. Die Stützglieder bestehen vorteilhafterweise aus einem Drahtbügel, zwischen dem wenigstens eine, vorzugsweise zwei in Lagern geführte Rollen angeordnet sind, an denen die Versorgungsleitung bei einer Schwenkbewegung des Stützgliedes bei Entnahme eines Handstückes aus seiner Ablage abrollen kann.Because both the supply lines and the support member of each handpiece whip on the device are operational, i.e. without the use of tools, are detachably held, a quick change is possible at any time even by a non-specialist. If also the supply line on the support member by operationally to be solved bracket or. Guide members is supported, so a change of only the supply line is possible without the associated support member needing to be removed for this purpose. The support members advantageously consist of a wire bracket, between which at least one, preferably two, rollers are arranged in bearings, on which the supply line can roll when the support member pivots when a handpiece is removed from its storage.

Der betriebsmäßig lösbare Anschluß der Versorgungsleitungen liegt vorteilhafterweise im Bereich der Ablage der Handstücke, also der Bedienseite des Gerätes zugewandt, der Anschluß der Stützglieder dagegen der Bedienseite abgewandt, also im rückwärtigen Teil des Gehäuses. Durch eine solche Anordnung wird in der Gebrauchslage eine relativ große Leitungslänge zur Verfügung gestellt, wodurch die "Reichweite" des Handstückes vergrößert wird. Besonders günstig ist es, wenn die Handstückablagen in das Gerätegehäuse integriert und darüber hinaus so gestaltet sind, daß die geräteseitigen Endabschnitte der Versorgungsleitungen gleichsam in einer Vertiefung dieser Ablage geführt sind. Zur betriebsmäßigen Halterung der Stützglieder am Gerät ist vorteilhafterweise ein Drehsegment vorgesehen, welches in einem am Gerätegehäuse befestigten Trägerteil - schwenkbeweglich gelagert ist. Dieses Drehsegment kann gleichsam als Schaltelement für eine im Trägerteil gehalterte Steuereinrichtung, vorzugsweise eine Lichtschranke, dienen.The operationally releasable connection of the supply lines is advantageously in the area of the storage of the handpieces, that is to say on the operating side of the device, while the connection of the support members on the other hand is turned away from the operating side, that is to say in the rear part of the housing. Such an arrangement provides a relatively long line length in the position of use, which increases the "range" of the handpiece. It is particularly expedient if the handpiece trays are integrated into the device housing and, moreover, are designed such that the device-side end sections of the supply lines are, as it were, guided in a recess in this tray. For the operational mounting of the support members on the device, a rotating segment is advantageously provided, which is pivotally mounted in a carrier part fastened to the device housing. This rotating segment can serve as a switching element for a control device, preferably a light barrier, held in the carrier part.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung näher erläutert.An embodiment of the invention is explained below with reference to the drawing.

Die Figur 1 zeigt in einer schaubildlichen Darstellung ein zahnärztliches Gerät mit einem pultförmigen Gehäuse 1, an dem mehrere, an Versorgungsleitungen 2 gebundene zahnärztliche Handstücke 3 bis 6 unterschiedlichen Durchmessers gehaltert sind. Bei den Handstücken handelt es sich von links nach rechts gesehen um ein Spritzhandstück 3, ein Turbinenhandstück 4, ein Elektromotorhandstuck 5 und ein Handstück zur Zahnsteinentfernung 6. Zur Halterung der Handstücke in der Nichtgebrauchslage - (Handstücke 3, 4 und 6) sind am Gehäuse 1 - schräg angeordnete Ablagevorrichtungen 7 vorgesehen. Diese Ablagevorrichtungen 7 sind, um eine möglichst glattflächige und hygienefreundliche Ablage zu erzielen, in das Gehäuse integriert angeordnet und durch mulden-bzw. schlitzförmige Vertiefungen 8 gebildet. Nachdem die Vertiefungen 8 gleichsam zur Führung der geräteseitigen Endabschnitte 2a der Versorgungsleitungen 2 dienen sollen, sind diese entsprechend ausgebildet, d.h. die - schlitzförmige Vertiefung erweitwert sich, ausgehend von einer etwa dem Durchmesser einer Versorgungsleitung entsprechenden Schlitzbreite, im Bereich 8a nach außen hin bis zu einer Weite, die eine Ablage der unterschiedlichen Handstücke in der dargestellten Form ermöglicht. Die Ablagevorrichtungen 7 sind in ihrer Ausführung identisch, so daß die an sich unterschiedlich gestalteten Handstücke, wie später noch näher erläutert, in beliebiger Reihenfolge am Gerät plaziert werden können. Die Versorgungsleitungen 2 sind mittels vorteilhafterweise an der Unterseite des Gerätes angeordneter Anschlußarmaturen 9, 10 in bekannter Weise mit den notwendigen Medienquellen - (Luft, Wasser, Strom) verbunden; auch hier sind sowohl die geräteseitigen als auch die - schlauchseitigen Armaturen für alle Handstücke gleich ausgebildet und unter anderem so gestaltet, daß bei gelöstem Anschluß die Medienzufuhr unterbrochen ist.1 shows a diagrammatic representation of a dental device with a desk-shaped housing 1, on which several dental handpieces 3 to 6 of different diameters are attached, which are bound to supply lines 2. The handpieces seen from left to right are an injection handpiece 3, a turbine handpiece 4, an electric motor handpiece 5 and a handpiece for removing tartar 6. For holding the handpieces in the non-use position - (handpieces 3, 4 and 6) are on the housing 1 - Slanted storage devices 7 are provided. In order to achieve the most smooth and hygienic storage possible, these storage devices 7 are arranged in an integrated manner in the housing and are formed by troughs. slot-shaped depressions 8 formed. Since the recesses 8 are to serve as it were to guide the device-side end sections 2a of the supply lines 2, they are designed accordingly, i.e. the slot-shaped depression widens, starting from a slot width corresponding approximately to the diameter of a supply line, in the area 8a to the outside, which enables the different handpieces to be stored in the form shown. The storage devices 7 are identical in their design, so that the handpieces, which are designed differently per se, as will be explained in more detail later, can be placed on the device in any order. The supply lines 2 are advantageously connected to the necessary media sources (air, water, electricity) in a known manner by means of connection fittings 9, 10 arranged on the underside of the device; here too, both the device-side and the hose-side fittings for all handpieces are of the same design and are designed, among other things, in such a way that the media supply is interrupted when the connection is disconnected.

Näheres über den Anschluß ist in der deutschen Patent anmeldung entsprechend DE-32 43 294 beschrieben.More about the connection is described in the German patent application corresponding to DE-32 43 294.

Etwa auf halber Länge sind die Versorgungsleitungen in Stützgliedern 11 so geführt, daß sie in der Nichtgebrauchslage in einer schräg aufwärts und von der Bedienstelle weg gerichteten Position gehalten werden. Die Stützglieder 11 bestehen vorteilhafterweise aus einem gebogenen Drahtbügel 12 mit etwa parallel verlaufenden Stäben 12a, 12b, deren Enden in einem Anschlußteil 13 gefaßt sind, welches so ausgeführt ist, daß es in der Ruhestellung der "Peitschen" die Gehäusekontur fortführt, d.h. die Oberfläche des Anschlußteils schließt bündig mit der Gehäuseobertläche ab. Der Drahtbügel 12 ist an seinem oberen Ende 12c leicht abgewinkelt und enthält in dem darunterliegenden Bereich zwei Abstützelemente 14, die unter anderem dafür sorgen, daß die Versorgungsleitung 2, wie dargestellt, schlaufenförmig gehalten wird.About half the length of the supply lines in support members 11 are guided so that they are held in the non-use position in an obliquely upward direction and away from the control point. The support members 11 advantageously consist of a curved wire bracket 12 with approximately parallel bars 12a, 12b, the ends of which are contained in a connecting part 13, which is designed so that it continues the housing contour in the rest position of the "whips", i.e. the surface of the connector is flush with the surface of the housing. The wire bracket 12 is slightly angled at its upper end 12c and contains two support elements 14 in the area below which, among other things, ensure that the supply line 2, as shown, is held in a loop.

Die Figur 3 zeigt in einer schaubildlichen Darstellung ein vom Gerät abgenommenes Stützglied 11 ohne Versorgungsleitung. Das Anschlußteil 13 ist spangenförmig ausgebildet und enthält einen oberen, mit einer Rastnase 16 versehenen Spangenabschnitt 13a und einen unteren Spangenabschnitt 13b. Die beiden Abstützelemente 14, die normalerweise am Drahtbügel 12 festgeklemmt sind, sind hier in einem aufgeklappten Zustand gezeichnet, in dem die Versorgungsleitung ohne Demontage von Handstück oder Anschlußarmatur entnommen werden kann.FIG. 3 shows a diagram of a support member 11 removed from the device without a supply line. The connecting part 13 is designed in the form of a clasp and contains an upper clasp section 13a provided with a locking lug 16 and a lower clasp section 13b. The two support elements 14, which are normally clamped to the wire bracket 12, are shown here in an opened state in which the supply line can be removed without dismantling the handpiece or connection fitting.

Die Figur 4 zeigt die Einzelteile eines Abstützelementes 14. Danach ist eine Rolle 17 vorgesehen, die zwischen beidseitig angeordneten und im montierten Zustand ineinandergesteckten Teilen 18 und 19 gelagert ist. Die beiden Teile 18 und 19 enthalten eine Klemmeinrichtung in Form von halbseitig offenen Klemmbuchsen 20 für eine leicht lösbare Befestigung an den beiden Stäben 12a, 12b des Drahtbügels 12. Diese Klemmung kann von Hand sehr leicht in und außer Eingriff gebracht werden. Um zu vermeiden daß bei stärkerem Zug am Handstück die Abstützelemente nicht mit dem Drahtbügel außer Eingriff kommen, erfolgt die Klemmung -wie dargestellt - zweckmäßigerweise von der Peitschenrückseite aus. Zu einem Wechsel eines Versorgungsschlauches brauchen die beiden Abstützelemente nur einseitig, wie in Figur 3 dargestellt, mit dem einem Stab 12a des Drahtbügels außer Eingriff gebracht und um den anderen Stab 12b geschwenkt werden; danach kann die Versorgungsleitung aus ihrer Führung innerhalb des Drahtbügels entnommen werden.FIG. 4 shows the individual parts of a support element 14. A roller 17 is then provided, which is mounted between parts 18 and 19 which are arranged on both sides and are nested in the assembled state. The two parts 18 and 19 contain a clamping device in the form of half-open clamping bushes 20 for an easily releasable attachment to the two rods 12a, 12b of the wire bracket 12. This clamping can be very easily brought in and out of engagement by hand. In order to avoid that the support elements do not come out of engagement with the wire bracket when there is a strong pull on the handpiece, the clamping — as shown — is expediently carried out from the back of the whip. To change a supply hose, the two support elements only need to be disengaged on one side, as shown in FIG. 3, with one rod 12a of the wire bracket and pivoted about the other rod 12b; the supply line can then be removed from its guide inside the wire bracket.

Obwohl an sich ein (gegebenenfalls größer dimensioniertes) Abstützelement 14 ausreichend wäre, so ist es doch vorteilhaft, zwei solcher Abstützelemente vorzusehen. Ebenso ist es denkbar, die halbseitig offene Klemmbuchse nur an einer Seite der Abstützelemente vorzusehen und die andere Seite als z.B. geschlossene Lager -bzw. Schwenkbuchse auszubilden. Die dargestellte Ausführungsform mit beidseitig offenen Klemmbuchsen ist jedoch der leichteren Auswechselbarkeit wegen besonders vorteilhaft.Although a (possibly larger) support element 14 would be sufficient in itself, it is nevertheless advantageous to provide two such support elements. It is also conceivable to provide the half-open socket on only one side of the support elements and the other side as e.g. closed warehouse or Train swivel bush. However, the embodiment shown with clamping bushes open on both sides is particularly advantageous because it is easier to replace.

Das Halteteil 13 ist betriebsmäßig, d.h. ohne Zuhilfenahme eines Werkzeuges, am Gerät gehaltert. Hierzu ist für jedes Stützglied 13 ein in den Figuren 5 bis 8 dargestelltes Drehsegment 21 vorgesehen. Dieses Drehsegment 21 ist wiederum in einem im Gerätegehäuse 1 fest montierten Trägerteil 22 schwenkbar gelagert, welches in Figur 10 in der Draufsicht und in Figur 11 in der Seitenansicht, teilweise im Schnitt, dargestellt ist.The holding part 13 is held in operation, ie without the aid of a tool, on the device. For this purpose, a rotating segment 21 shown in FIGS. 5 to 8 is provided for each support member 13 seen. This rotary segment 21 is in turn pivotally mounted in a support part 22 which is fixedly mounted in the device housing 1 and which is shown in FIG. 10 in plan view and in FIG. 11 in side view, partly in section.

Das Drehsegment 21 enthält eine Lagerachse 23, die in am Trägerteil 22 angeordneten, halbseitig offenen Lagerbuchsen 24 eingeschnappt werden können. Im Bereich der Lagerachse 23 weist das Drehsegment 21 eine Führungsnut 25 auf, in die im montierten Zustand der untere Abschnitt 13b der beiden Spangenabschnitte 13a, 13b des Halteteils 13 eingreift. Mit 26 ist eine Vertiefung bezeichnet, in die die im oberen Spangenabschnitt 13a angeordnete Rastnase 16 des Halteteils 13 einrastet und das Stützglied 11 gegen unbeabsichtigtes axiales Lösen sichert.The rotating segment 21 contains a bearing axis 23 which can be snapped into bearing bushes 24 which are arranged on the carrier part 22 and are open on one side. In the area of the bearing axis 23, the rotating segment 21 has a guide groove 25, into which the lower section 13b of the two clasp sections 13a, 13b of the holding part 13 engages in the assembled state. A recess is designated by 26, into which the locking lug 16 of the holding part 13 arranged in the upper clasp section 13a engages and secures the support member 11 against unintentional axial loosening.

Anschlußteile 13 ohne Drahtbügel können als sogenannte Blindabdeckblenden auf das Drehsegment 21 aufgeschoben werden, wenn an dieser Stelle kein Handstück mit Versorgungsschlauch benötigt wird, wie in Figur 1 (zwischen Handstück 5 und 6) gezeigt (Position 13a).Connection parts 13 without a wire bracket can be pushed onto the rotating segment 21 as so-called blind covers if no handpiece with supply hose is required at this point, as shown in FIG. 1 (between handpiece 5 and 6) (position 13a).

Das Drehsegment 21 enthält weiterhin eine nach unten offene Ausnehmung 27 und eine Bohrung 28, in die eine Stellschraube 29 eingeführt werden kann. In die Ausnehmung 27 wird eine in Figur 9 dargestellte Stellmutter 30 eingelegt, die durch die Stellschraube 29 im Drehsegment 21 gesichert ist. Die Stellmutter 30 enthält einen Haken 31, an dem eine an einem Zapfen 32 des Trägerteils 22 (Figuren 10/11) eingehängte Zugfeder 33 angreift. Mittels der Zugfeder 33 wird die notwendige Rückstellkraft für das Stützglied 11 erzeugt. Die Rückstellkraft kann durch Verstellen der Stellschraube 29 relativ zur Stellmutter 30 individuell je nach Bestückung des Handstückes und der gewünschten Rückstellkraft eingestellt werden.The rotating segment 21 also contains a downwardly open recess 27 and a bore 28 into which an adjusting screw 29 can be inserted. An adjusting nut 30 shown in FIG. 9 is inserted into the recess 27 and is secured in the rotating segment 21 by the adjusting screw 29. The adjusting nut 30 contains a hook 31 on which a tension spring 33 which is suspended on a pin 32 of the carrier part 22 (FIGS. 10/11) acts. The necessary restoring force for the support member 11 is generated by means of the tension spring 33. The restoring force can be adjusted individually by adjusting the adjusting screw 29 relative to the adjusting nut 30 depending on the equipment of the handpiece and the desired restoring force.

Das Trägerteil 22 weist beidseitig Auslegerarme 35 auf, an denen Aufnahmebuchsen 36 zur Halterung einer aus Sender und Empfänger bestehenden Lichtschranke vorgesehen sind. Die Lichtschranke wird gesteuert von dem in Figur 5 mit 37 bezeichneten, die Stellschraube 29 aufnehmenden Fortsatz am Drehsegment 21; dieser Fortsatz unterbricht den Lichtstrom zwischen Sender und Empfänger bei abgelegtem Handstück und aktiviert die Steuereinrichtung, wenn das Stützglied 11 bei Entnahme eines Handstückes aus der Ablage nach vorne, also zur Bedienseite hin, geschwenkt wird.The carrier part 22 has cantilever arms 35 on both sides, on which receiving bushings 36 are provided for holding a light barrier consisting of transmitter and receiver. The light barrier is controlled by the extension on the rotary segment 21, designated 37 in FIG. 5 and receiving the set screw 29; this extension interrupts the luminous flux between the transmitter and receiver when the handpiece is put down and activates the control device when the support member 11 is pivoted forwards, ie towards the operating side, when a handpiece is removed from the deposit.
