Description

Die Erfindung betrifft eine Ablagevorrichtung für zahnärztliche Arbeitsutensilien, insbesondere Instrumentarium u. dgl., mit einem auf einer Halterung mit horizontaler Auflagefläche auflegbarem Aufnahmeteil, welches die Utensilien direkt oder indirekt über ein Ablagetablett aufnimmt und dessen äußere Begrenzung wenigstens teilweise am Umfang einen Rand mit in bezug auf die Ablagefläche des Aufnahmeteils nach unten gezogenem Randendteil enthält.The invention relates to a storage device for dental work utensils, especially instruments and. Like., With a receptacle part that can be placed on a holder with a horizontal support surface, which receives the utensils directly or indirectly via a storage tray and the outer boundary of which at least partially contains an edge on the circumference with an edge end part pulled downward with respect to the storage surface of the receiving part.

Zur Ablage und Bereitstellung von zahnärztlichen Arbeitsutensilien, insbesondere Instrumentarium, verwendet der Zahnarzt Aufnahmeteile in Form sogenannter Trays oder Kassetten, die in entsprechenden Vertiefungen von meist auf Tragarmen montierten speziellen Halterungen ablegbar sind (US-A-33 46 957).For the storage and provision of dental work utensils, in particular instruments, the dentist uses receiving parts in the form of so-called trays or cassettes, which can be stored in corresponding recesses of special brackets usually mounted on support arms (US-A-33 46 957).

Auf dem Markt haben sich bisher zwei in ihren Abmessungen genormte, in ihrer Größe jedoch voneinander abweichende Trays eingeführt. Um dem Kunden die Benutzung sowohl des einen als auch anderen Trays zu ermöglichen, sind vom Gerätehersteller Halterungen für beide Traygrößen anzubieten. Dies bedeutet jedoch eine erhöhte Lagerhaltung. Ein späteres Auswechseln der Trayhalterung beim Kunden ist mit erhöhten Umrüstungskosten verbunden.So far, two standardized trays have been introduced on the market, but their sizes differ from one another. To enable the customer to use both one and the other tray, the device manufacturer has to offer holders for both tray sizes. However, this means increased inventory. Later replacement of the tray holder at the customer is associated with increased conversion costs.

Aus der DE-A-19 53 694 ist eine Halterung für in horizontaler Ebene verschwenkbare Instrumententabletts mit nach oben stehendem Rand bekannt, bei der entsprechend einer bevorzugten Ausführungsform das das Tablett aufnehmende Lagerteil von der Seite gesehen in Form eines liegenden U ausgebildet ist. Der untere Schenkel des U-förmigen Lagerteils ist als breite Auflagelasche ausgebildet, der obere Schenkel weist ein den in den Lagerteil eingeführten Rand des aufzunehmenden Instrumententabletts hintergreifendes Sicherungselement auf. Dieses Sicherungselement ist in einer Ausführungsform in Form eines schwenkbar gelagerten Hebels, der mehrere den Rand hintergreifende Zähne enthält, ausgebildet.DE-A-19 53 694 discloses a holder for instrument trays which can be pivoted in the horizontal plane and has an upstanding edge, in which, according to a preferred embodiment, the bearing part receiving the tray is in the form of a lying U when viewed from the side. The lower leg of the U-shaped bearing part is designed as a broad support tab, the upper leg has a securing element which engages behind the edge of the instrument tray to be accommodated which is inserted into the bearing part. In one embodiment, this securing element is designed in the form of a pivotably mounted lever which contains a plurality of teeth which engage behind the edge.

Abgesehen davon, daß die bekannte Konstruktion ausschließlich zur Halterung von Tabletts mit nach oben gezogenem Rand geeignet ist, beinhaltet die dort aufgezeigte Hebelanordnung vorstehende Teile, die nicht nur aus hygienischer Sicht zu vermeiden sind, sondern auch noch den Nachteil haben, daß ein versehentliches Betätigen erfolgen und damit das Tablett ungewollt aus seiner Halterung herausfallen kann. Des weiteren ist bei dieser Ausführungsform und auch bei den anderen, in der genannten Schrift aufgezeigten Lösungsvorschlägen, insbesondere bei dem Vorschlag einer Arretierung des Tabletts mittels eines herausnehmbaren Bolzens, die. Handhabung relativ umständlich und erlaubt keine Einhandbedienung.Apart from the fact that the known construction is only suitable for holding trays with the edge pulled upwards, the lever arrangement shown there contains protruding parts which are not only to be avoided from a hygienic point of view, but also have the disadvantage that they are operated accidentally and so that the tray can accidentally fall out of its holder. Furthermore, in this embodiment and also in the other proposed solutions indicated in the cited document, in particular in the proposal of locking the tray by means of a removable bolt, the. Handling relatively cumbersome and does not allow one-handed operation.

Der im Anspruch 1 angegebenen Erfindung liegt die Aufgabe zugrunde, eine Ablagevorrichtung der eingangs genannten Gattung zu schaffen, die keine vorstehenden und deshalb zu Fehlbedienungen neigenden Halte- oder Arretierungsglieder aufweist und bei der das Aufnahmeteil, welches die Arbeitsutensilien direkt oder indirekt über eine Kassette aufnehmen kann, relativ einfach und leicht (Einhandbedienung) vom Benutzer gegen ein anderes Aufnahmeteil, z. B. zum Zwecke eines leichteren Vorbestückens oder Reinigens bzw. Sterilisierens des Aufnahmeteils, ausgewechselt werden kann.The invention specified in claim 1 has for its object to provide a storage device of the type mentioned, which has no protruding and therefore prone to incorrect operation holding or locking members and in which the receiving part, which can accommodate the work utensils directly or indirectly via a cassette , relatively simple and easy (one-handed operation) by the user against another receiving part, e.g. B. for the purpose of easier pre-loading or cleaning or sterilizing the receiving part, can be replaced.

Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind in den Unteransprüchen angeführt. Ein Ausführungsbeispiel der Erfindung wird nachfolgend anhand der Zeichnung näher erläutert.Advantageous refinements and developments of the invention are set out in the subclaims. An embodiment of the invention is explained below with reference to the drawing.

Es zeigen :

  • Figur 1 die erfindungsgemäße Ablagevorrichtung in einer Seitenansicht,
  • Figuren 2 und 5 Teile der Vorrichtung nach Figur 1 im Schnitt.
  • Figuren 3 und 4 Querschnittsprofil von zwei verschiedenen Aufnahmeteilen.
Show it :
  • FIG. 1 shows the storage device according to the invention in a side view,
  • Figures 2 and 5 parts of the device of Figure 1 in section.
  • Figures 3 and 4 cross-sectional profile of two different receiving parts.

Die Figur 1 zeigt die erfindungsgemäße Ablagevorrichtung in einer Seitenansicht. An einer Wand- oder Bodensäule 1 ist ein abgewinkelter Haltearm 2 schwenkbar gehaltert. Dieser Haltearm ist ortsfester Träger eines abnehmbar gehalterten, in der Darstellung gestrichelt angedeuteten Aufnahmeteils 3 für z. B. Instrumentarium. Das Aufnahmeteil 3 kann das Instrumentarium direkt oder indirekt über ein oder mehrere Tabletts (Kassetten) aufnehmen. Das Aufnahmeteil 3 enthält wenigstens teilweise am Umfang, vorzugsweise jedoch umlaufend über den gesamten Umfang, einen geformten (umgebördelten) Rand 4 mit gleichbleibendem Profilquerschnitt (Figuren 3 oder 4). Der Rand 4 weist einen in bezug auf die Auflagefläche 5 hochgezogenen oberen Randteil 4a und einen nach unten auslaufenden unteren Randendteil 4b auf. Im oberen Randbereich ist der Rand 4 mit einer Abschrägung 6 versehen.Figure 1 shows the storage device according to the invention in a side view. An angled holding arm 2 is pivotally supported on a wall or floor column 1. This holding arm is a fixed support of a detachably mounted, shown in dashed lines in the receiving part 3 for z. B. Instruments. The receiving part 3 can record the instruments directly or indirectly via one or more trays (cassettes). The receiving part 3 contains, at least partially on the circumference, but preferably all around the circumference, a shaped (flanged) edge 4 with a constant profile cross section (FIGS. 3 or 4). The edge 4 has an upper edge part 4a which is pulled up with respect to the bearing surface 5 and a lower edge end part 4b which runs downwards. The edge 4 is provided with a bevel 6 in the upper edge region.

Der Haltearm 2 weist ein etwa bis zur Mitte des Aufnahmeteils 3 reichendes Stützteil 7 auf, auf den ein in Richtung des Pfeiles 8 längsverschiebbar geführtes Tragteil 9 gehaltert ist. Das Tragteil 9 enthält an seinem freien, etwa auf halber Breite des Aufnahmeteils liegenden Ende eine Auflage- bzw. Stützfläche 10 und an seinem anderen Ende eine durch beispielsweise einen Hinterschnitt gebildete Vertiefung 11, in die der untere Randendteil 4b des Aufnahmeteils 3 formschlüssig eingreifen kann. In der Eingriffsposition ist das Aufnahmeteil gegen Herausziehen und auch gegen Verdrehen gesichert. Der Haltearm 2 enthält außerdem in einem der Randhöhe entsprechenden Abstand von der Vertiefung einen Vorsprung 12, der die Abschrägung 6 des Aufnahmeteils 3 im gehalterten Zustand etwas übergreift. Durch den Vorsprung ist das Aufnahmeteil flächenmäßig geführt und bei versehentlichem Anstoßen von unten her gegen Herausfallen gesichert.The holding arm 2 has a support part 7 which extends approximately to the center of the receiving part 3 and on which a support part 9 which is guided in the direction of the arrow 8 and is longitudinally displaceable is held. The support part 9 contains at its free end, which is approximately half the width of the receiving part, a support or support surface 10 and at its other end a depression 11 formed by, for example, an undercut, into which the lower edge end part 4b of the receiving part 3 can engage in a form-fitting manner. In the engaged position, the receiving part is secured against pulling out and also against twisting. The holding arm 2 also contains, at a distance from the depression corresponding to the edge height, a projection 12 which somewhat overlaps the bevel 6 of the receiving part 3 in the held state. Due to the projection, the receiving part is guided in terms of area and is secured against falling out if it is accidentally bumped from below.

Die Auflagefläche 10 wird (Figur 2) durch zwei übereinander angeordnete, in einer entsprechenden Ausnehmung im Tragteil 9 eingebettete, gegen Anlageflächen 9a des Tragteils 9 aufliegende Einlageteile 16a, 16b gebildet. Das Einlageteil 16b ist mit Abstandsstegen 16c versehen und kann um 180° gewendet eingelegt werden. In der dargestellten Einlageposition wird eine gegenüber der übrigen Oberfläche des Tragteils 9 etwas erhöhte Auflagefläche und in der anderen Einlageposition, in der die Abstandsstege 16c nicht zum Tragen kommen, eine mit der übrigen Oberfläche bündige Auflagefläche gebildet. Durch diese Wahlposition kann hinsichtlich ihrer Randausbildungen unterschiedlich gestalteten Aufnahmeteilen Rechnung getragen werden. Die Wahlposition kann vorteilhafterweise am Einlegeteil markiert sein.The contact surface 10 is formed (FIG. 2) by two insert parts 16a, 16b which are arranged one above the other and are embedded in a corresponding recess in the support part 9 and bear against contact surfaces 9a of the support part 9. The insert part 16b is provided with spacer webs 16c and can be inserted turned through 180 °. In the insert position shown, a somewhat increased contact surface is formed compared to the rest of the surface of the support part 9, and in the other insert position, in which the spacer webs 16c do not come into play, a contact surface which is flush with the rest of the surface is formed. With this choice position, differently designed receiving parts can be taken into account with regard to their edge configurations. The selection position can advantageously be marked on the insert.

Das Tragteil 9 besteht aus Kunststoff und ist mittels eines durch Druckfeder 13 belasteten Bolzens 14 in einem Langloch 15 des Stützteils 7 federbelastet geführt, wobei durch die Federwirkung das Tragteil 9 zum Stützteil 7 hin gedrückt wird.The support member 9 is made of plastic and is guided in a spring-loaded manner in a slot 15 of the support member 7 by means of a bolt 14 loaded by compression spring 13, the support member 9 being pressed toward the support member 7 by the spring action.

Das Tragteil 9 ist mit einem hochstehenden Rand 9b versehen, mit dem es an der korrespondierenden Fläche des Stützteils 7 bzw. Haltearmes 2 anliegen kann. Mittels einer am Rand 9b angespritzten federnden Zunge 9c (Figur 5) wird eine gewisse Vorspannung und damit Lagestabilisierung für das Tragteil 9 geschaffen.The support part 9 is provided with a raised edge 9b, with which it can rest against the corresponding surface of the support part 7 or holding arm 2. By means of a resilient tongue 9c molded onto the edge 9b (FIG. 5), a certain pretension and thus position stabilization for the supporting part 9 are created.

In der gezeichneten Eingriffsposition, in der das Aufnahmeteil 3 am Haltearm 2 gehaltert ist, liegt ein Zapfen 17 an einem vorteilhafterweise einstellbaren Anschlag 18 des Stützteils 7 an. Wird das Tragteil 9 durch Anheben an dem zweckmäßigerweise als Griff ausgebildeten Endteil 19 angehoben, so kommt der Zapfen 17 über den Anschlag 18 zu liegen. Unterstützt durch die federnde Zunge 9c wird das Tragteil in Richtung des Pfeiles 8 so weit herausgeschoben, bis eine Kante 20 an einem weiteren Anschlag 21 des Stützteils 7 anliegt. In dieser Position liegt der Rand 4 außerhalb des Vorsprungs 12, wodurch das Aufnahmeteil 3 leicht abgenommen werden kann.In the illustrated engagement position, in which the receiving part 3 is held on the holding arm 2, a pin 17 bears against an advantageously adjustable stop 18 of the support part 7. If the supporting part 9 is raised by lifting the end part 19, which is expediently designed as a handle, the pin 17 comes to rest over the stop 18. Supported by the resilient tongue 9c, the supporting part is pushed out in the direction of arrow 8 until an edge 20 abuts another stop 21 of the supporting part 7. In this position, the edge 4 lies outside the projection 12, as a result of which the receiving part 3 can be easily removed.

Das Aufstecken geschieht in umgekehrter Reihenfolge, d. h., zunächst wird das Aufnahmeteil 3 mit dem unteren Randendteil 4b in die Vertiefung 11 eingesetzt. Sodann wird das Tragteil 9 entgegen der Richtung des Pfeiles 8 leicht eingeschoben. Die Schräge kommt dabei unter den Vorsprung zu liegen. Anschließend wird das Tragteil 9 nach unten gedrückt, wodurch der Zapfen 17 wieder am Anschlag 18 zur Anlage kommt.The attachment takes place in reverse order, i. that is, the receiving part 3 with the lower edge end part 4b is first inserted into the depression 11. Then the support member 9 is inserted slightly counter to the direction of arrow 8. The slope comes under the ledge. Then the support member 9 is pressed down, whereby the pin 17 comes to rest against the stop 18.

Es sei darauf hingewiesen, daß die Randausbildung und Größe des Aufnahmeteils an sich beliebig sein kann. Die Figuren 3 und 4 zeigen beispielsweise zwei unterschiedlich gestaltete Profile, die für das Aufnahmeteil 3 in Frage kommen. Wenn, wie vorteilhafterweise vorgeschlagen, das Aufnahmeprofil ein umlaufendes, im Querschnitt gleichbleibendes Randprofil aufweist, kann das Aufnahmeteil an jeder beliebigen geraden Außenkante gehaltert werden. Auch ein nachträgliches Verschieben ist leicht möglich. Ausgehend von einem solchen Grundprofil können an einem solchen Aufnahmeteil in gleicher Weise weitere Aufnahmeelemente, wie z. B. Medikamentenbehälter, Filmbetrachter oder auch Griffe, gehaltert werden.It should be noted that the edge formation and size of the receiving part can be arbitrary. Figures 3 and 4 show, for example, two differently designed profiles that are suitable for the receiving part 3. If, as advantageously proposed, the receiving profile has a peripheral edge profile that remains the same in cross section, the receiving part can be held on any straight outer edge. Subsequent moving is also easily possible. On the basis of such a basic profile, further receiving elements such as, for example, B. medication containers, film viewers or handles are held.
