Abstract
Description
Die vorliegende Erfindung betrifft ein Kranken- oder Pflegebett gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a hospital or nursing bed according to the preamble of claim 1.
Derartige Kranken- oder Pflegebetten, der Einfachheit halber wird im folgenden nur auf ein Krankenbett verwiesen, sind so konzipiert, daß ihre Liegefläche um eine gedachte Querachse schwenkbar ist, so daß insbesondere das kopfseitige Ende der Liegefläche gegenüber dem Fußende abgesenkt werden kann. Dies ist aus medizinischen Gründen vielfach erforderlich.Such hospital or nursing beds, for the sake of simplicity, reference is made below only to a hospital bed, are designed so that their lying surface is pivotable about an imaginary transverse axis, so that in particular the head-side end of the bed can be lowered relative to the foot. This is often necessary for medical reasons.
Aus
Die Absenkung des Kopfendes der Liegefläche erfolgt bisher entweder rein mechanisch oder durch eine entsprechend ausgebildete, über Nocken mit Endschaltern auslösbare Motorschaltung, durch die ein ausschließlich zur Verschwenkung der Liegefläche vorgesehener Motor entsprechend ein- und ausfahrbar ist.The lowering of the head end of the lying surface is done either purely mechanically or by a suitably trained, can be triggered via cams with limit switches motor circuit through which a provided exclusively for pivoting the bed surface motor according to and retractable.
Allerdings weist die bekannte Motor-Lösung sowohl bei der Herstellung des Krankenbettes wie auch bei dessen Betrieb erhebliche Nachteile auf.However, the known motor solution, both in the production of the hospital bed as well as in its operation significant disadvantages.
So sind zunächst einmal die relativ hohen Fertigungskosten zu nennen, die durch den zusätzlichen Einbau eines Motors für die Verschwenkung der Liegefläche, einschließlich der notwendigen Bauteile für die Motorschaltung, wie die genannten Nocken und Endschalter entstehen.So are first of all the relatively high manufacturing costs to mention, which arise through the additional installation of a motor for the pivoting of the bed, including the necessary components for the motor circuit, such as the cams and limit switches mentioned.
Darüber hinaus ist die Absenkung der Liegefläche in eine untere Lage bei einer Unterbrechung der Stromversorgung, bei einem fehlenden oder defekten Akku, oder bei einem elektrischen Defekt des Motors nicht möglich, wodurch sich naturgemäß Handhabungsprobleme ergeben.In addition, the lowering of the bed surface in a lower layer in an interruption of the power supply, a missing or defective battery, or in an electrical failure of the engine is not possible, which naturally arise handling problems.
Dies trifft gleichermaßen für eine Situation zu, in der die Liegefläche spontan in eine als Trendelenburg-Stellung bekannte Kopftieflage gebracht werden muß, da der Motor als quasi starres Koppelglied eine in diesem Fall wünschenswerte manuelle Verschwenkung der Liegefläche nicht zuläßt.This is equally true for a situation in which the lying surface must be spontaneously brought into a head depression position known as the Trendelenburg position, since the motor as a quasi-rigid coupling member does not permit a manual pivoting of the lying surface which is desirable in this case.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Krankenbett der gattungsgemäßen Art so weiter zu entwickeln, daß es kostengünstiger herstellbar ist, seine Betriebssicherheit verbessert und die Handhabung sicherer wird.The present invention is therefore based on the object to develop a hospital bed of the generic type so that it is cheaper to produce, improves its reliability and handling is safer.
Diese Aufgabe wird durch ein Krankenbett gelöst, das die Merkmale des Anspruchs 1 aufweist.This object is achieved by a hospital bed having the features of claim 1.
Ein solcher Art ausgebildetes Krankenbett zeichnet sich zunächst einmal dadurch aus, daß es einfacher und kostengünstiger herstellbar ist, da außer auf den Motor zur Höhenverstellung auf zusätzliche elektrische Aggregate einschließlich diverser Motorschaltungen bzw. Schaltungsteile verzichtet werden kann.Such a kind of trained hospital bed is initially characterized by the fact that it is easier and cheaper to produce, since except for the engine height adjustment can be dispensed with additional electrical units including various engine circuits or circuit parts.
Eine Bewegung der Liegefläche im Sinne eines Absenkens sowohl kopf- wie fußseitig ist nun manuell möglich, was auch eine Verbesserung hinsichtlich der Betriebssicherheit mit sich bringt.A movement of the lying surface in the sense of a lowering both head and foot side is now possible manually, which also brings an improvement in terms of reliability with it.
Da ein elektrisches Aggregat zur genannten Verschwenkung der Liegefläche fehlt, ist eine Behinderung dieser Verstellung durch Stromausfall oder Versagen des Aggregates ausgeschlossen.Since an electric aggregate for said pivoting of the bed area is missing, obstructing this adjustment is excluded by power failure or failure of the unit.
Selbst bei einem elektrischen Defekt des Motors zur Höhenverstellung der Liegefläche ist diese sowohl von einer hochgestellten Position in eine abgesenkte bringbar wie auch in die bereits erwähnte Trendelenburg-Stellung, in der die Liegefläche fußseitig angehoben wird, so daß das Kopfende dem Fußteil gegenüber tiefer liegt.Even with an electrical defect of the motor for height adjustment of the lying surface, this can be brought from a raised position into a lowered position as well as in the already mentioned Trendelenburg position, in which the lying surface is raised on the foot, so that the head end is lower compared to the foot part.
Nach einer vorteilhaften Weiterbildung der Erfindung ist vorgesehen, die beiden Schwenkbeschläge, die abständig zueinander einerseits an der Liegefläche und andererseits am Untergestell angelenkt sind, durch ein Koppelglied miteinander zu verbinden, das sowohl teleskopierbar wie auch in gewünschten unterschiedlichen Längen blockierbar ist.According to an advantageous embodiment of the invention, the two pivot fittings that are hinged to each other on the one hand on the bed surface and on the other hand, connected to the base by a coupling member to each other, which is both telescopic and lockable in desired different lengths.
In Blockierstellung stellt das Koppelglied, das vorzugsweise aus einer blockierbaren Gasfeder gebildet ist, eine starre Verbindung zwischen den beiden Schwenkbeschlägen dar, durch deren dann mögliche parallele Bewegung eine entsprechende Lageveränderung der Liegefläche möglich ist, beispielsweise um die Liegefläche parallel zum Untergestell anzuheben.In the blocking position, the coupling member, which is preferably formed from a blockable gas spring, a rigid connection between the two pivot fittings, through which then possible parallel movement a corresponding change in position of the bed is possible, for example, to raise the bed parallel to the frame.
Bei Auslösung der Blockade und bei gleichzeitiger Unterbrechung der Wirkverbindung zwischen dem Motor und dem daran angeschlossenen Schwenkbeschlag können beide Schwenkbeschläge in ihrer Bewegung unterschiedlich sein, wodurch sich die Niveauveränderung vom Kopf- zum Fußteil oder umgekehrt ergibt.Upon release of the blockade and simultaneous interruption of the operative connection between the motor and the pivot fitting connected thereto both pivot fittings may be different in their movement, resulting in the change in level from the head to the foot or vice versa.
Die Unterbrechung der Wirkverbindung des Motors, der, wie erwähnt, einseitig an einem ersten der Schwenkbeschläge angeschlossen ist und andererseits starr mit dem Untergestell verbunden ist, wird ermöglicht durch ein an sich bekanntes einschiebbares Hubrohr des Motors, dessen Eingriff mit einer Antriebsspindel mechanisch zu unterbrechen ist.The interruption of the operative connection of the motor, which, as mentioned, is unilaterally connected to a first of the swivel fittings and on the other rigidly connected to the base is made possible by a known per se stroke tube of the motor, the engagement with a drive spindle is mechanically interrupt ,
Zum Ausrücken des Motors ist eine Betätigungsstange vorgesehen, die, je nach Ausbildung einer Ausrückeinrichtung des Motors, als Druck- oder Zugstange ausgebildet ist, die wiederum betätigt wird von einer Lenkerlasche, die Bestandteil des zweiten Schwenkbeschlages ist, der dem gegenüber liegt, an dem der Motor angeschlossen ist.To disengage the motor, an actuating rod is provided, which, depending on the design of a disengagement of the motor, is designed as a push or pull rod, which in turn is actuated by a handlebar lug, which is part of the second pivot fitting, which is opposite to where the Motor is connected.
Dabei erfolgt die Unterbrechung der Wirkverbindung des Motors mit dem angeschlossenen ersten Schwenkbeschlag, d. h. die Betätigung der Ausrückeinrichtung nur dann, wenn das Koppelglied teleskopierbar ist.The interruption of the operative connection of the motor with the connected first pivot fitting, d. H. the actuation of the disengaging device only when the coupling member is telescopic.
Die Aufhebung der Blockade des Koppelgliedes erfolgt zweckmäßigerweise mittels einer Griffstange oder Betätigungshebel an der Liegefläche bzw. einem zugeordneten Matratzenrahmen. Denkbar ist aber auch, daß die Aufhebung der Blockade im Motor durch ein Fußpedal erfolgt, das am Untergestell befestigt ist. In jedem Fall kann so die Liegefläche stromlos parallel, also ohne Schwenkung, abgesenkt werden.The lifting of the blockage of the coupling member is advantageously carried out by means of a handle bar or operating lever on the bed or an associated mattress frame. It is also conceivable that the lifting of the blockage in the engine by a foot pedal, which is attached to the base. In any case, so the lying surface can be lowered without current parallel, ie without pivoting.
Für einen Freilauf der Lenkerlasche an der Betätigungsstange ist darin ein axial sich erstreckendes Langloch vorgesehen, in dem die Lenkerlasche endseitig geführt ist und erst in einer Endstellung im Sinne eines Drückens oder Ziehens zum Eingriff kommt. In den übrigen Bewegungsphasen der Liegefläche befindet sich der Motor in Wirkverbindung mit dem angeschlossenen Schwenkbeschlag.For a freewheel of the handlebar lug on the actuating rod an axially extending slot is provided therein, in which the handlebar lug is guided end and only comes in an end position in the sense of pushing or pulling for engagement. In the remaining movement phases of the lying surface, the motor is in operative connection with the connected pivot fitting.
Weitere vorteilhafte Ausbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Further advantageous embodiments of the invention are characterized in the subclaims.
