Anwendungsgebiet der ErfindungField of application of the invention

Die Erfindung betrifft eine Haltevorrichtung fur medizinische Beobachtungsgerate, wobei das Beobachtungsgerat über zwei als Gelenkparallelogramm ausgebildete Tragarme schwenkbar an einer Säule befestigt ist und eine mit dem Gelenkparallelogramm verbundene Feder zum Ausgleich des Gerategewichts vorgesehen ist Sie ist bei der Augenprufung, aber auch in der Augenheilkunde und der Mikrochirurgie anwendbarThe invention relates to a holding device for medical observation devices, the observation device is pivotally mounted on two columns designed as a joint parallelogram support arms on a pillar and connected to the Gelenkparallelogramm spring is provided to compensate for the device weight is in the eye examination, but also in ophthalmology and the Microsurgery applicable

Charakteristik der bekannten technischen LosungenCharacteristic of the known technical solutions

Bei Vorrichtungen zur Prüfung der Sehscharfe und des Binokularsehens ist es bekannt (DD-WP 226187), fur das rechte und das linke Auge des Patienten je ein separates Projektionssystem zur Abbildung von Testmarken und Korrekturlmsen vorzusehen, wobei jedes Projektionssystem um zwei jeweils senkrecht zueinander verlaufende Achsen schwenkbar und entlang dieser Achse verschiebbar istIn devices for examining visual acuity and binocular vision, it is known (DD-WP 226187) to provide for the right and left eye of the patient each have a separate projection system for imaging test marks and Korrekturlmsen, each projection system about two mutually perpendicular axes is pivotable and displaceable along this axis

Unter anderem zur Positionierung des Patienten auf dem Untersuchungsstuhl ist es sinnvoll, die gesamte Projektionseinrichtung, vorzugsweise nach oben, wegzuschwenkenAmong other things, for positioning the patient on the examination chair, it makes sense to wegzuschwenken the entire projection device, preferably upwards

Aufgrund der unsymmetrischen Lagerung der Projektionssysteme und des damit verbundenen extrem außermittigen Massenschwerpunktes sind die Halterungen starken Belastungen, insbesondere Torsionskraften, ausgesetzt Es ist bereits bekannt, bei optischen Beobachtungsgeraten ein verstellbares Stativ zu verwenden, das aus einem als Gelenkparallelogramm ausgebildeten Tragarm besteht Ein solcher Parallelogrammarm mit U-formigen Tragern kann ohne Deformation nur geringe Kräfte aufnehmen, da die erforderliche Torsionssteifigkeit nicht gegeben istDue to the asymmetrical mounting of the projection systems and the associated extremely eccentric center of gravity, the brackets are exposed to heavy loads, especially torsional forces. It is already known to use an adjustable tripod in optical observation devices, which consists of a trained as Gelenkparallelogramm support arm Such a Parallelogrammarm with U -formigen wearers can absorb only small forces without deformation, since the required torsional rigidity is not given

Ziel der ErfindungObject of the invention

Ziel der Erfindung ist eine Haltevorrichtung, die ein Verschwenken des Gerätes realisiert, wobei das Platznehmen des Patienten ohne jegliche Behinderung erfolgtThe aim of the invention is a holding device which realizes a pivoting of the device, wherein the seating of the patient takes place without any hindrance

Darlegung des Wesens der ErfindungExplanation of the essence of the invention

Aufgabe der Erfindung ist die Realisierung einer schwenkbaren Halterung unter Verwendung eines Parallelogrammarms, die eine hohe Torsionssteifigkeit aufweistThe object of the invention is the realization of a pivotable holder using a Parallelogrammarms, which has a high torsional rigidity

Erfindungsgemaß wird die Aufgabe bei einer Haltevorrichtung nach dem Oberbegriff des Hauptanspruchs durch die kennzeichnenden Merkmale des ersten Anspruchs gelostAccording to the invention the object is achieved in a holding device according to the preamble of the main claim by the characterizing features of the first claim

Bevorzugte Weiterbildungen sind in den Unteranspruchen beschriebenPreferred developments are described in the subclaims

Durch die spezielle Ausfuhrung des Parallelogrammarms werden die auftretenden Torsionskrafte von dem als Hohlkörper ausgebildeten Tragarm aufgenommen und dadurch eine ausreichende Festigkeit erreicht Unerwünschte Deformationen werden dadurch vermieden Überraschend hat sich gezeigt, daß die erfmdungsgemaße Haltevorrichtung überall angewendet werden kann, wo der bisher übliche Parallelogrammarm Verwendung fand Die Vorteile sind eine höhere Festigkeit bei möglicher Materialeinsparung und daraus folgendem geringerem GewichtDue to the special execution of the Parallelogrammarms occurring torsional forces are absorbed by the formed as a hollow body support arm and thereby achieved sufficient resistance Unwanted deformations are avoided Surprisingly, it has been shown that the erfmdungsgemaße holding device can be used anywhere where the previously common Parallelogrammarm use found The Advantages are a higher strength with possible material savings and consequent lower weight

Ausführungsbeispielembodiment

Die Erfindung wird nachstehend anhand der schematischen Darstellung in Fig. 1 näher erläutert.The invention is explained below with reference to the schematic representation in Fig. 1 in more detail.

An einer Säule 1, die seitlich neben dem nicht dargestellten Patientenstuhl steht, ist an einer festen Drehachse 2 der als Hohlkörper ausgebildete Tragarm 3 des Parallelogrammarms gelagert. Eine zweite Drehachse 4 ist in fester Beziehung zur Drehachse 2 in der Säule 1 gelagert. Sie bildet die Schwenkachse des zweiten Tragarms 5, der innerhalb des Tragarms 3 verläuft.On a column 1, which is laterally adjacent to the patient chair, not shown, is mounted on a fixed axis of rotation 2 of the trained as a hollow body support arm 3 of the Parallelogrammarms. A second axis of rotation 4 is mounted in a fixed relationship to the axis of rotation 2 in the column 1. It forms the pivot axis of the second support arm 5, which extends within the support arm 3.

An der Fortsetzung des Tragarms 3 greift eine Zugfeder 6 an, die mit ihrem anderen Ende ebenfalls an Säule 1 fest gelagert ist.At the continuation of the support arm 3 engages a tension spring 6, which is also fixedly mounted with its other end to column 1.

Durch die Feder 6 wird das Gewicht des Tragarms und des zu schwenkenden Gerätes ausgeglichen.By the spring 6, the weight of the support arm and the device to be pivoted is compensated.

Zur geräteseitigen Verbindung der beiden Arme des Parallelogrammarms ist eine Koppel 7 vorgesehen, deren Lagerung im Tragarm 3 als hohle Achse 8 ausgebildet ist.For device-side connection of the two arms of the Parallelogrammarms a coupling 7 is provided, the bearing is formed in the support arm 3 as a hollow axis 8.

In der hohlen Achse 8 sind zwei Traghülsen 9 und 10 gelagert, die zueinander und zur hohlen Achse 8 rotatorisch und translatorisch beweglich sind.In the hollow axis 8, two support sleeves 9 and 10 are mounted, which are rotationally and translationally movable relative to each other and to the hollow axis 8.

Die Traghülsen 9 und 10 tragen stilförmige Arme 11 und 12, die zur Halterung von zwei (gestrichelt angedeuteten) Projektoren 13 und 14 dienen.The support sleeves 9 and 10 carry stile-shaped arms 11 and 12, which serve to support two (dashed lines indicated) projectors 13 and 14.

An der Koppel 7 sind zwei Stellgetriebe 15 und 16 befestigt, welche die rotatorische Bewegung je eines stielförmigen Armes über Kupplungsglieder 17 bewirken. Für Arm 11 ist das Kupplungsglied über einen zusätzlichen Hebel 18 mit Traghülse 10 verbunden.At the coupling 7 two actuating gear 15 and 16 are fixed, which cause the rotational movement depending on a stalk-shaped arm via coupling members 17. For arm 11, the coupling member is connected via an additional lever 18 with support sleeve 10.

Beim Platznehmen des Patienten wird der Parallelogrammarm in eine obere Stellung geschwenkt (zum Beispiel durch manuelle Verschiebung mittels eines am Tragarm befestigten Griffes).When the patient is seated, the parallelogram arm is pivoted to an upper position (for example, by manual displacement by means of a handle attached to the support arm).
