Abstract
Description
Die Erfindung betrifft eine Schnelllösevorrichtung, und insbesondere betrifft sie eine Schnelllösevorrichtung einer für ein elektrisches Krankenbett geeigneten Stelleinrichtung.The Invention relates to a quick release device, and in particular it relates to a quick-release device for electric Hospital bed suitable adjusting device.
Es ist gut bekannt, dass Stelleinrichtungen bei elektrischen Krankenbetten, Laufbändern und Rollstühlen in weitem Umfang dazu verwendet werden können, Positionen oder Neigungen derselben einzustellen. Wenn ein Patient einer medizinischen Notbehandlung unterzogen wird, kann mittels einer Schnelllösevorrichtung, mit der an der Stelleinrichtung ein Schnelllösevorgang ausgeführt werden kann, die Position des Betts, auf dem er liegt, schnell eingestellt werden, um damit die Zeit zum Retten des Patienten optimal zu nutzen. Daher ist es sehr wichtig, zuverlässig funktionierende Schnelllösevorrichtungen für Stelleinrichtungen zu schaffen.It It is well known that adjusting devices in electrical hospital beds, treadmills and wheelchairs can be used to a great extent, positions or inclinations to stop it. If a patient has a medical emergency treatment can be subjected by means of a quick release device, with at the Actuator a quick release accomplished The position of the bed on which it lies can be quickly adjusted to optimally use the time to rescue the patient. Therefore, it is very important to have reliable quick release devices for adjusting devices to accomplish.
Im Dokument TW-B-M275836 ist eine herkömmliche Schnelllösevorrichtung für eine Stelleinrichtung offenbart. Die Stelleinrichtung verfügt über eine Motoreinrichtung und eine Übertragungseinrichtung. Die Motoreinrichtung verfügt über einen Motor und eine Schnecke, die vom Zentrum desselben aus nach außen steht. Die Übertragungseinrichtung verfügt über eine Gewindestange, ein mit einem Ende derselben verbundenes Schneckenrad, das mit der Schnecke in Eingriff steht, und ein Sitzgehäuse, das ein Ende der Gewindestange und des Schneckenrads bedeckt. Die Schnelllösevorrichtung nutzt einen Dreharm und ein mit einem Ende desselben verbundenes Kabel dazu, die Kupplungswirkung zwischen dem Schneckenrad und der Schnecke zu kontrollieren, um dadurch den Schnelllösevorgang für die Stelleinrichtung zu bewerkstelligen.in the Document TW-B-M275836 is a conventional quick release device for one Actuator disclosed. The actuator has a Motor device and a transmission device. The engine device has a Motor and a worm, which stands out from the center of the same. The transmission device has one Threaded rod, a worm wheel connected to one end thereof, which is engaged with the worm, and a seat housing, the one End of the threaded rod and the worm wheel covered. The quick release device uses a pivot arm and a connected to one end thereof Cable to the coupling effect between the worm wheel and the To control the worm, thereby the quick release process for the Actuating device to accomplish.
Wenn sich die herkömmliche Schnelllösevorrichtung für eine Stelleinrichtung in Gebrauch befindet, bestehen jedoch immer noch einige Nachteile. Da der Dreharm durch einen solchen Drehpunkt auf das Sitzgehäuse drückt, das er auf bogenförmige Weise verschwenkt, ändert sich die Richtung der auf den Dreharm und das Kabel wirkenden Kräfte dauernd. Im Ergebnis muss eine relativ große Kraft aufgewandt werden, und die Bedienung ist nicht ganz gleichmäßig. Ferner muss das Sitzgehäuse mit Löchern zum Einsetzen des Dreharms versehen werden, wodurch Feuchtigkeit oder Staub in es eindringen kann, was zu einer Korrosion der Komponenten im Inneren und einer erheblichen Verkürzung der Lebensdauer führt.If the traditional ones Quick release device for one Actuator is in use, but still exist some disadvantages. Since the rotary arm by such a fulcrum on the seat housing suppressed, he in a bow-shaped way pivots, changes the direction of the forces acting on the rotating arm and the cable is continuous. As a result, a relatively large force must be expended and the operation is not quite even. Furthermore, the seat housing with holes be fitted for insertion of the rotary arm, whereby moisture or dust can penetrate it, resulting in corrosion of the components in the Inside and a significant shortening of the life leads.
Der Erfindung liegt die Aufgabe zugrunde, eine Schnelllösevorrichtung für eine Stelleinrichtung zu schaffen, die so aufgebaut ist, dass auf das von einem Bediener zu bedienende Kabel eine relativ kleine Zugkraft auszuüben ist.Of the Invention is based on the object, a quick release device for one To provide adjusting device which is constructed so that on the operator-to-use cables have a relatively small pulling force exercise is.
Diese Aufgabe ist durch die Schnelllösevorrichtung gemäß dem beigefügten Anspruch 1 gelöst. Bei ihr ist eine Zugstangenanordnung mit einem Schwenkarm zum Übertragen einer bogenförmigen Schwenkbewegung in eine Linearverschiebung verbunden, was zur gewünschten Verringerung der aufzubringenden Zugkraft führt.These Task is through the quick release device according to the appended claim 1 solved. at her is a pull rod assembly with a swivel arm for transmitting an arcuate pivoting movement connected to a linear displacement, resulting in the desired Reduction of the applied tensile force leads.
Vorteilhafterweise ist eine Zugeinrichtung fest in einem oberen Gehäuse angebracht, das ein unteres Gehäuse bedeckt, wodurch das Zusammenbauen der Stelleinrichtung vereinfacht werden kann und damit die Zusammenbauzeit verkürzt werden kann.advantageously, a pulling device is fixedly mounted in an upper housing, the lower one casing covered, thereby simplifying the assembly of the actuator can be shortened and thus the assembly time can be shortened.
Ferner ist es von Vorteil, das obere und das untere Gehäuse integral abgedichtet herzustellen, wozu wasserdichte Dichtungen zwischen dem oberen Gehäuse und der Zugstange angebracht werden, wodurch Staubdichtigkeit, Wasserdichtigkeit und Feuchtigkeitsdichtigkeit erzielt werden.Further it is advantageous to make the upper and lower housing integrally sealed, including waterproof seals between the upper housing and the drawbar attached which are dust-proof, waterproof and moisture-proof be achieved.
Die Erfindung wird nachfolgend von anhand von Figuren veranschaulichten Ausführungsformen näher erläutert.The Invention will be illustrated below with reference to figures Embodiments explained in more detail.
