Description

Die Erfindung betrifft eine Vorrichtung zum Verlagern von Patienten mit einem auf Rollen gelagerten fahrbaren Gestell, einer an diesem freitragend angeordneten Plattform und einem Transportband, das die Oberseite und die Unterseite der Plattform mindestens teilweise überdeckt, um die freie patientennahe Längskante der Plattform herumgeführt und mittels einer Antriebsvorrichtung in beiden Richtungen verstellbar ist.The invention relates to a device for moving patients with a mobile frame mounted on rollers, a cantilevered platform arranged on this and a conveyor belt that at least partially covers the top and bottom of the platform, guided around the free longitudinal edge of the platform near the patient and by means of a Drive device is adjustable in both directions.

Eine Vorrichtung dieser Art ist beispielsweise aus dem deutschen Gebrauchsmuster 87 04 343 bekannt. Bei dieser Vorrichtung wird die Plattform relativ zum Gestell bewegt, wobei das Band entweder zusammen mit der Plattform oder relativ zu dieser bewegt werden kann. Nachteilig bei allen Ausführungsformen von derartigen Vorrichtungen, sogenannten Umbettern, mit nur einem Transportband ist, daß beim Unterschieben der Plattform unter den Patienten und gleichzeitiger Aufnahme des Patienten auf die Plattform das über die Unterseite der Plattform laufende Bandteil am Bettlaken reibt und dieses verschiebt. Dies erschwert eine reibungslose Aufnahme des Patienten auf die Plattform. Während der Ablage des Patienten auf das Bett ergibt sich der umgekehrte Vorgang.A device of this type is known for example from German utility model 87 04 343. In this device, the platform is moved relative to the frame, and the belt can be moved either together with the platform or relative to it. A disadvantage of all embodiments of such devices, so-called Umbetetten, with only one conveyor belt is that when the platform is pushed under under the patient and at the same time taking the patient onto the platform, the band part running over the underside of the platform rubs against the bed sheet and moves it. This makes it difficult for the patient to be taken on the platform smoothly. The reverse process occurs when the patient is placed on the bed.

Es sind bereits Umbetter bekannt, die zwei übereinanderliegende Plattformen verwenden, über die jeweils ein Band läuft. Durch geeignete Steuerung der beiden Bänder kann der oben beschriebene Nachteil vermieden werden. Allerdings ist diese Lösung relativ aufwendig und kompliziert sowohl hinsichtlich des mechanischen Aufwandes als auch hinsichtlich der Steuerung.Umbetter are already known that use two superimposed platforms, each of which runs a belt. The disadvantage described above can be avoided by suitable control of the two bands. However, this solution is relatively complex and complicated both in terms of mechanical effort and in terms of control.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art anzugeben, die einfach in ihrem Aufbau ist und dennoch eine reibungslose Aufnahme und Ablage von Patienten aus dem Bett bzw. in das Bett ermöglicht.The invention has for its object to provide a device of the type mentioned, which is simple in construction and yet allows a smooth reception and storage of patients from the bed or in the bed.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Transportband ausgehend von einer ersten im Gestell gelagerten Aufwickelwalze über die Oberseite der Plattform, um deren freie Längskante herum, entlang der Plattformunterseite, um eine im Gestell gelagerte zweite Aufwickelwalze herum zu einer nahe dem freien Längsrand der Plattform unterhalb derselben angeordneten Umlenkkante und um diese herum zur zweiten Aufwickelwalze zurückgeführt ist und daß die Bandenden so auf die Aufwickelwalzen auflaufen, daß sich diese beim Auf- und Abwickeln jeweils gleichsinnig drehen.This object is achieved in that the conveyor belt starting from a first winding roller mounted in the frame over the top of the platform, around its free longitudinal edge, along the underside of the platform, around a second winding roller mounted in the frame to a near the free longitudinal edge of the platform below the same arranged deflection edge and around this is returned to the second winding roller and that the ends of the tape run onto the winding rollers so that they each rotate in the same direction during winding and unwinding.

Die vorstehend beschriebene Lösung verwendet nur ein Band, wobei auch nur eine Antriebsvorrichtung zum Antrieb einer der beiden Aufwickelwalzen beim Aufwickeln bzw. Abwickeln erforderlich ist. Trotz dieser konstruktiv und steuerungstechnisch einfacheren Lösung lassen sich mit der erfindungsgemäßen Lösung die gleichen Vorteile erreichen, die sonst nur üblicherweise mit zwei getrennten Bändern bzw. Plattformen erreicht werden. Durch die erfindungsgemäße Bandführung wird erreicht, daß sich das zur Auflage auf dem Patientenbett oder Bettlaken kommende Untertrumm des Bandes und das über die Oberseite der Plattform laufende Obertrumm des Bandes, das den Patienten aufnehmen soll, unabhängig von der Laufrichtung des Bandes stets gleichsinnig bewegen. Damit läßt sich der oben beschriebene Nachteil zuverlässig vermeiden. Die Plattform läßt sich aufgrund der Bandbewegungen des Untertrumms und des Obertrumms mit nur geringem Widerstand zwischen den Patienten und das Bettlaken einschieben, wobei das Bettlaken nicht durch die Reibung an dem Banduntertrumm verschoben wird.The solution described above uses only one band, and only one drive device is required to drive one of the two winding rollers during winding or unwinding. Despite this solution, which is simpler in terms of construction and control technology, the solution according to the invention can achieve the same advantages which are otherwise usually only achieved with two separate belts or platforms. The tape guide according to the invention ensures that the lower run of the tape coming to rest on the patient bed or bed sheet and the upper run of the tape running over the top of the platform, which is intended to accommodate the patient, always move in the same direction, regardless of the direction of travel of the tape. The disadvantage described above can thus be reliably avoided. The platform can be inserted with little resistance between the patient and the bed sheet due to the belt movements of the lower run and the upper run, the bed sheet not being displaced by the friction on the belt lower run.

Um die Plattform einschließlich der Bänder möglichst flach zu halten, ist die Umlenkkante vorzugsweise von einer Leiste gebildet, die in eine Aussparung an der Unterseite der Plattform eintaucht und mit der Plattform verbunden ist. Auf diese Weise ist die gesamte Anordnung nur unwesentlich dicker als die Plattform selber.In order to keep the platform, including the straps, as flat as possible, the deflection edge is preferably formed by a strip which dips into a recess on the underside of the platform and is connected to the platform. In this way, the entire arrangement is only slightly thicker than the platform itself.

Die Plattform selbst kann höhenverstellbar an dem Gestell angeordnet sein, so daß sie auf verschiedene Betthöhen einstellbar ist.The platform itself can be arranged height-adjustable on the frame, so that it can be adjusted to different bed heights.

Zum Verschieben des Umbetters ist an dem Gestell auf der der Plattform fernen Seite eine sich parallel zu dieser erstreckende Griffstange befestigt. Zur Erleichterung der Bedienung ist erfindungsgemäß vorgesehen, daß die Bedienungselemente für die Antriebssteuerung in der Griffstange angeordnet sind.To move the converter, there is a parallel to the frame on the side remote from the platform this extending handlebar attached. To facilitate operation, the invention provides that the operating elements for the drive control are arranged in the handle bar.

Da die Aufwickelwalzen gleichsinnig angetrieben werden, ist es zur Vereinfachung zweckmäßig, wenn beide Aufwikkelwalzen ständig mit der Antriebseinrichtung gekoppelt sind, beispielsweise über eine gemeinsame Antriebskette. In diesem Falle tritt jedoch das Problem auf, daß beim Wechsel der Aufwickelrichtung die bandabgebende Aufwickelwalze des größeren Wickeldurchmessers mehr Band abgibt als die synchron angetriebene, das Band aufnehmende Walze mit ihrem noch kleineren Durchmesser aufnehmen kann. Dies kann dazu führen, daß das Band Falten schlägt und beschädigt wird.Since the winding rollers are driven in the same direction, it is expedient for simplification if both winding rollers are constantly coupled to the drive device, for example via a common drive chain. In this case, however, the problem arises that when the winding direction is changed, the tape-dispensing winding roller of the larger winding diameter releases more tape than the synchronously driven, the tape-receiving roller with its even smaller diameter can take up. This can cause the tape to wrinkle and become damaged.

Um dies zu vermeiden, wird erfindungsgemäß vorgeschlagen, daß zwischen den Aufwickelwalzen und der Antriebseinrichtung jeweils ein Drehspiel vorgesehen ist und daß jede der Aufwickelwalzen in ihre Aufwickelrichtung vorgespannt ist.To avoid this, it is proposed according to the invention that a rotational play is provided between the winding rollers and the drive device and that each of the winding rollers is biased in its winding direction.

Auf diese Weise kann trotz der ständigen Kopplung der beiden Aufwickelwalzen mit der Antriebseinrichtung und trotz des sich ändernden Durchmessers der Aufwickelwalzen durch das Abwickeln bzw. Aufwickeln des Bandes sichergestellt werden, daß das Band stets gespannt bleibt. Das Drehspiel muß dabei natürlich so bemessen sein, daß es den zu erwartenden Längenunterschied beim Aufwickeln des Bandes auf die eine Aufwickelwalze einerseits und beim Abwickeln des Bandes von der anderen Aufwickelwalze andererseits ausgleichen kann.In this way, despite the constant coupling of the two winding rollers with the drive device and despite the changing diameter of the winding rollers by unwinding or winding the tape, it can be ensured that the tape always remains tensioned. The rotational play must of course be such that it can compensate for the expected difference in length when winding the tape on one take-up roller on the one hand and when unwinding the tape from the other take-up roller on the other.

Bei einer besonders einfach zu realisierenden und zweckmäßigen Ausführungsform ist erfindungsgemäß vorgesehen, daß die Aufwickelwalzen jeweils auf einer Welle drehbar gelagert sind, wobei die Wellen mit der Antriebseinrichtung gekoppelt sind und der Drehwinkel der jeweiligen Aufwickelwalze gegenüber ihrer Welle durch Anschläge begrenzt ist, und daß zwischen der jeweiligen Aufwickelwalze und ihrer Welle eine Feder zur Erzeugung der Vorspannung angeordnet ist.In a particularly simple to implement and expedient embodiment, the invention provides that the winding rollers are each rotatably mounted on a shaft, the shafts are coupled to the drive device and the angle of rotation of the respective winding roller relative to its shaft is limited by stops, and that between the respective winding roller and its shaft, a spring for generating the bias is arranged.

Der in den Figuren 1 und 2 dargestellte mobile Umbetter zum Transport und zur Verlagerung von Patienten umfaßt ein allgemein mit 10 bezeichnetes Gestell mit zwei kurzen horizontalen Querholmen 12 und einem sie verbindenden Längsholm 14, die jeweils auf Rollen 16 gelagert sind. An den Verbindungsstellen der Querholme 12 mit dem Längsholm 14 sind vertikale Säulen 18 angeordnet, an denen eine allgemein mit 20 bezeichnete Plattform zur Aufnahme und zum Transport eines Patienten freitragend und höhenverstellbar angeordnet ist. Dabei ist die Plattform 20 an einem an den Säulen 18 vertikal verstellbar geführten, einen Längsträger 22 und zwei Querträger 24 umfassenden Rahmen befestigt. Da die Höhenverstellung der Plattform 20 in an sich bekannter Weise auf eine beliebige Art erfolgen kann, wird sie hier nicht näher beschrieben.Further features and advantages of the invention will become apparent from the following description, which in connection with the accompanying drawings explains the invention using an exemplary embodiment.

The mobile Umbetter shown in Figures 1 and 2 for the transport and transfer of patients comprises a frame, generally designated 10 with two short horizontal cross members 12 and a longitudinal spar 14 connecting them, each of which is mounted on rollers 16. At the junctions of the cross bars 12 with the longitudinal spar 14 are arranged vertical columns 18, on which a platform, generally designated 20, for accommodating and transporting a patient is arranged in a self-supporting and height-adjustable manner. The platform 20 is fastened to a frame which is vertically adjustable on the columns 18 and comprises a longitudinal beam 22 and two cross beams 24. Since the height of the platform 20 can be adjusted in any manner in a manner known per se, it is not described in more detail here.

Innerhalb der Säulen 18 und des Längsträgers 22 sind zwei Aufwickelwalzen 26 und 28 drehbar gelagert, die über einen nicht dargestellten Kettentrieb mit einer in Figur 3 nur schematisch angedeuteten Antriebsvorrichtung 30 verbunden sind. Diese ist über eine Bedienungstastatur 32 steuerbar, die in einer auf der Rückseite des Umbetters parallel zur Längsrichtung der Plattform 20 verlaufenden Griffstange 35 angeordnet ist, so daß sie von der Bedienungsperson bequem bedient werden kann.Within the columns 18 and the longitudinal beam 22, two winding rollers 26 and 28 are rotatably mounted, which are connected via a chain drive, not shown, to a drive device 30, which is only schematically indicated in FIG. This can be controlled via an operating keyboard 32 which is arranged in a handle bar 35 running on the rear of the converter parallel to the longitudinal direction of the platform 20, so that it can be operated comfortably by the operator.

Gemäß der Darstellung in Figur 3 ist das eine Bandende mit der oberen Aufwickelwalze 26 verbunden und von dieser über die Oberseite 34 der Plattform 20, um die freie Randkante 36 der Plattform 20 herum zur Plattformunterseite 38 geführt. Von hier aus verläuft das Band zu den Säulen 18 zurück und ist ausgehend vom gestellseitigen Ende der Plattform 20 um die zweite Aufwickelwalze 28 herum wieder in Richtung auf den freien Plattformrand 36 geführt. Nahe dem freien Plattformrand 36 und unterhalb der Plattform 20 befindet sich eine Umlenkleiste 40, die parallel zum freien Plattformrand 36 verläuft und an ihren Längsenden mithilfe von Bolzen 42 (Figur 2) an der Plattform 20 befestigt ist. Das Transportband 44 ist um diese Umlenkleiste 40 herum nun zurück zur zweiten Aufwickelwalze 28 geführt, wobei es auf diese in der zur Aufwickelwalze 26 entgegengesetzten Aufwickelrichtung aufläuft.According to the illustration in FIG. 3, the one band end is connected to the upper take-up roller 26 and is guided from the latter over the upper side 34 of the platform 20, around the free edge 36 of the platform 20 to the underside 38 of the platform. From here, the belt runs back to the columns 18 and, starting from the end of the platform 20 on the frame side, is guided around the second winding roller 28 again in the direction of the free platform edge 36. Near the free platform edge 36 and below the platform 20 there is a deflection strip 40 which runs parallel to the free platform edge 36 and is fastened to the platform 20 at its longitudinal ends by means of bolts 42 (FIG. 2). The Conveyor belt 44 is now guided around this deflection strip 40 back to the second winding roller 28, where it runs onto the latter in the winding direction opposite to the winding roller 26.

Wird das Transportband 44 zur Aufnahme eines Patienten in der durch die Pfeile angegebenen Richtung angetrieben, wobei es genügt, die Aufwickelwalze 26 anzutreiben, so erkennt man, daß sich das Untertrumm 46 und das Obertrumm 48 des Transportbandes gleichsinnig bewegen ebenso wie die miteinander in Berührung stehenden Zwischenabschnitte 50 und 52 des Transportbandes. Wird die Drehrichtung umgekehrt, so ergeben sich gleiche Umlaufverhältnisse nur in der entgegengesetzten Richtung. Wird bei der Aufnahme des Patienten die Plattform zwischen den Patienten und das Bettlaken mit einer geeigneten Geschwindigkeit eingeschoben, so findet keine Relativbewegung zwischen dem Transportband und dem Bettlaken statt, so daß dieses nicht verschoben wird. Die Plattform läßt sich ohne größeren Widerstand unter den Patienten einschieben. Die gleichen Verhältnisse ergeben sich nur in umgekehrter Drehrichtung bei der Ablage des Patienten.If the conveyor belt 44 is driven to accommodate a patient in the direction indicated by the arrows, it being sufficient to drive the winding roller 26, it can be seen that the lower run 46 and the upper run 48 of the transport belt move in the same direction as those in contact with one another Intermediate sections 50 and 52 of the conveyor belt. If the direction of rotation is reversed, the same circulation conditions only result in the opposite direction. If the platform is inserted between the patient and the bed sheet at a suitable speed when the patient is being taken in, there is no relative movement between the conveyor belt and the bed sheet, so that this is not shifted. The platform can be inserted under the patient without any great resistance. The same conditions only arise in the opposite direction of rotation when the patient is placed down.

Mit 54 ist in Figur 1 ein Sicherungsbügel bezeichnet, der zur Aufnahme eines Patienten hochgeklappt werden kann und dazu dient, das Herunterfallen des Patienten von der Plattform zu verhindern. Der Bügel ist in Figur 2 nicht dargestellt.1 in FIG. 1 denotes a securing bracket which can be folded up to accommodate a patient and which serves to prevent the patient from falling off the platform. The bracket is not shown in Figure 2.

In Figur 4 erkennt man ähnlich wie in Figur 3 die beiden Aufwickelwalzen 26 und 28. Diese sind von Hohlzylindern gebildet, die jeweils auf einer Welle 56 bzw. 58 frei drehbar gelagert sind. Mit jeder der Wellen ist ein radialer Fortsatz 60 verbunden, der jeweils in einen sektorförmigen Ausschnitt 62 in der jeweiligen Aufwickelwalze 26 bzw. 28 eingreift. Der Winkelbereich, über den sich der sektorförmige Ausschnitt 62 erstreckt, bestimmt ein Drehspiel zwischen der jeweiligen Aufwickelwalze 26 bzw. 28 und ihrer Welle 56 bzw. 58.In FIG. 4, similar to FIG. 3, the two winding rollers 26 and 28 can be seen. These are formed by hollow cylinders, each of which is freely rotatably mounted on a shaft 56 or 58. A radial extension 60 is connected to each of the shafts a sector-shaped cutout 62 engages in the respective winding roller 26 or 28. The angular range over which the sector-shaped cutout 62 extends determines a rotational play between the respective winding roller 26 or 28 and its shaft 56 or 58.

Jede der Wellen 56, 58 ist mit einem Kettenzahnrad 64 bzw. 66 drehfest verbunden und wird über eine Kette 68 angetrieben, die über ein Kettenzahnrad 70 läuft, das seinerseits mit der Antriebswelle 72 einer im übrigen nicht dargestellten Antriebseinrichtung drehfest verbunden ist.Each of the shafts 56, 58 is non-rotatably connected to a sprocket wheel 64 or 66 and is driven by a chain 68 which runs over a sprocket wheel 70 which in turn is non-rotatably connected to the drive shaft 72 of a drive device (not shown).

Jede der Aufwickelwalzen 26, 28 ist durch eine schematisch angedeutete Feder 74 in ihre Aufwickelrichtung vorgespannt. Für die Aufwickelwalze 26 ist dies die Drehrichtung im Uhrzeigersinn und für die Aufwickelwalze 28 ist dies die Drehrichtung gegen den Uhrzeigersinn. Für die Erzeugung dieser Vorspannung kann jede geeignete Feder auch beispielsweise eine Torsionsfeder gewählt werden.Each of the winding rollers 26, 28 is biased in its winding direction by a schematically indicated spring 74. For the winding roller 26, this is the direction of rotation in the clockwise direction and for the winding roller 28, this is the direction of rotation in the counterclockwise direction. Any suitable spring, for example a torsion spring, can also be selected to generate this preload.

Diese Anordnung hat folgende Aufgabe. Angenommen, das Band sei auf eine der Aufwickelwalzen aufgerollt. Dann ist der Durchmesser dieser Aufwickelwalze einschließlich des Bandwickels größer als der Durchmesser der anderen Aufwickelwalze. Wenn nun die Aufwickelrichtung umgekehrt wird, wäre bei synchronem und gleichsinnigem Antrieb der beiden Wellen 56, 58 die Bandaufnahme auf der aufwickelnden Walze geringer als die Bandabgabe an der bandabgebenden Walze. Dies würde dazu führen, daß das Band zwischen den beiden Aufwickelwalzen durchhängt oder Falten schlägt und dann leicht beschädigt werden kann. Die zwischen der jeweiligen Aufwickelwalze und ihrer zugehörigen Welle angeordnete Feder bewirkt aufgrund des vorhandenen Drehspiels, daß die Aufwickelwalze stets in Aufwickelrichtung vorgespannt wird. Sofern das Drehspiel groß genug ist, kann damit ein Durchhängen oder ein Faltenschlagen des Bandes vermieden werden.This arrangement has the following task. Assume that the tape is rolled up on one of the take-up rollers. Then the diameter of this winding roller including the tape roll is larger than the diameter of the other winding roller. If the winding direction is now reversed, if the two shafts 56, 58 are driven synchronously and in the same direction, the tape take-up on the winding roller would be less than the tape delivery on the tape-dispensing roller. This would cause the tape to sag or wrinkle between the two take-up rollers and then be easily damaged. The spring arranged between the respective take-up roller and its associated shaft causes the take-up roller due to the existing rotational play is always biased in the winding direction. If the turning play is large enough, sagging or folding of the tape can be avoided.
