Description

Die Erfindung betrifft eine Hebe- und Transportvorrichtung für Kranke oder Behinderte gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a lifting and transport device for the sick or disabled according to the preamble of claim 1.

Durch die zunehmende Personalnot, insbesondere in Krankenhäusern, Senioren- und Behindertenheimen wird es immer wichtiger, dem Betreungspersonal Arbeitserleichterungen zu verschaffen. So sind z.B. zum Anheben von Patienten, z.B. zum Bettenmachen, zum Verlegen auf eine Krankentrage oder umgekehrt zum Verlegen von einer Krankentrage auf ein Bett, im allgemeinen wenigstens zwei Personen notwendig, wenn sich der Patient selbst nicht bewegen oder mithelfen kann. Gleiches gilt für ein Umlegen von einer Krankentrage oder einem fahrbaren Bett auf einen Behandlungstisch, wie z.B. einen Operationstisch, für die Computertomographie, zum Röntgen u.dgl.Due to the increasing shortage of staff, especially in hospitals, retirement homes and homes for the disabled, it is becoming more and more important to make work easier for care staff. For example, to lift patients, for example to make beds, to lay on a stretcher or vice versa to lay a stretcher on a bed, generally at least two people are necessary if the patient himself cannot move or help. The same applies to moving from a stretcher or a mobile bed to a treatment table, such as an operating table, for computed tomography, X-rays and the like.

Bekannt sind bereits einfache Hebeeinrichtungen, durch die bettlägrige Patienten z.B. in eine Badewanne gelegt werden können. Die bekannten Vorrichtungen sind jedoch zum einen relativ unbequem in der Bedienung und zum anderen nicht transportabel. Weiterhin ist häufig für die ausreichende Versorgung des Patienten doch noch eine zweite Person notwendig.Simple lifting devices are already known, through which bedridden patients e.g. can be placed in a bathtub. However, the known devices are relatively uncomfortable to use on the one hand and not portable on the other. Furthermore, a second person is often necessary to ensure adequate patient care.

Dokument US-A-2 565 536 beschreibt eine Vorrichtung gemäß dem Oberbegriff des Anspruchs 1.Document US-A-2 565 536 describes an apparatus according to the preamble of claim 1.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Hebe- und Transportvorrichtung für Kranke und Behinderte zu schaffen, die sehr universell einsetzbar ist, wobei zum Versorgen des Kranken oder Behinderten im Bedarfsfalle nur eine Person erforderlich ist, insbesondere wobei gleichzeitig auch eine Transportmöglichkeit gegeben ist.The present invention is therefore based on the object to provide a lifting and transport device for the sick and disabled, which can be used very universally, only one person being required to care for the sick or disabled if necessary, in particular with a transport option being provided at the same time .

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß das Basisteil (1) durch einen Motorantrieb (4) verfahrbar ist, daß das Basisteil (1) mit ausfahrbaren oder ausschwenkbaren Stützen (29) versehen ist und daß zur Durchführung der verschiedenen Bewegungen von Basisteil (1), Kranarm (9,14), Trageinrichtung (17), Stützen (29) und dergleichen eine Fernsteuereinrichtung (28) vorgesehen ist.According to the invention, this object is achieved in that the base part (1) can be moved by a motor drive (4), in that the base part (1) is provided with extendable or pivotable supports (29) and in that the various movements of the base part (1) are carried out. , Crane arm (9, 14), support device (17), supports (29) and the like, a remote control device (28) is provided.

Die erfindungsgemäße Hebe- und Transportvorrichtung ist sehr universell einsetzbar, wobei zu dessen Bedienung im Bedarfsfalle nur eine Person notwendig ist. So kann der Patient nicht nur durch die Trageinrichtung angehoben werden, sondern durch den Kranarm gleichzeitig auch noch seitlich bewegt werden. Wird zusätzlich noch die Verfahrbarkeit des Basisteiles benützt, so kann der angehobene Patient sogar noch über größere Strecken transportiert werden.The lifting and transport device according to the invention can be used very universally, only one person being required to operate it if necessary. In this way, the patient can not only be lifted by the carrying device, but can also be moved laterally by the crane arm. If the movability of the base part is also used, the raised patient can be transported even over longer distances.

In einer sehr vorteilhaften Weiterbildung der Erfindung ist vorgesehen, daß der Kranarm und die Trageinrichtung durch hydraulische Einrichtungen verstellbar und bewegbar sind.In a very advantageous development of the invention it is provided that the crane arm and the support device can be adjusted and moved by hydraulic devices.

Durch die Verwendung einer Hydraulikeinheit in Verbindung mit einer elektrischen und/oder elektronischen Steuerung über eine Batterie oder einen Akku als Energiequelle ist die erfindungsgemäße Vorrichtung von einer externen Energieversorgung unabhängig, womit sie sehr universell einsetzbar ist. Im Bedarfsfalle ist es lediglich erforderlich, für die elektrisch oder elektronisch betätigten Teile oder andere elektrische Zusatzeinrichtungen eine Batterie oder einen Akku vorzusehen, der bei Nichtbenutzung der Vorrichtung auf einfache Weise aufgeladen werden kann. Im allgemeinen wird man die Batterie oder den Akku im Basisteil anordnen.By using a hydraulic unit in conjunction with an electrical and / or electronic control system via a battery or a rechargeable battery as the energy source, the device according to the invention is independent of an external energy supply, which makes it very universally applicable. If necessary, it is only necessary to provide a battery or rechargeable battery for the electrically or electronically operated parts or other electrical additional devices, which can be charged in a simple manner when the device is not in use. In general you will arrange the battery in the base part.

Wenn in einer erfindungsgemäßen Weiterbildung vorgesehen ist, daß das Basisteil durch einen Motorantrieb verfahrbar ist, wird die Arbeit für die Betreuungsperson noch weiter erleichtert, denn auf diese Weise kann der Transport automatisch erfolgen.If it is provided in a further development according to the invention that the base part can be moved by a motor drive, the work for the caregiver is made even easier, because in this way the transport can take place automatically.

Damit in einfacher Weise auch Kurvenfahrten möglich sind, kann vorgesehen sein, daß für zwei sich gegenüberliegende Räder des Basisteiles je eine Antriebseinrichtung vorhanden ist, die unabhängig voneinander steuerbar sind.So that cornering is also possible in a simple manner, it can be provided that for two opposite wheels of the base part there is a drive device which can be controlled independently of one another.

Durch eine entsprechend unterschiedliche Ansteuerung der Antriebseinrichtungen kann damit das verfahrbare Basisteil Kurvenfahrten durchführen.By means of a correspondingly different actuation of the drive devices, the movable base part can therefore perform cornering.

Zur Drehmomentübertragung kann vorgesehen sein, daß hierfür ein Reibradantrieb in dem Basisteil angeordnet ist. Selbstverständlich sind im Rahmen der Erfindung jedoch auch noch andere Antriebs- und Steuermöglichkeiten denkbar.For torque transmission it can be provided that a friction wheel drive is arranged in the base part. Of course, other drive and control options are also conceivable within the scope of the invention.

Zur Stabilisierung und zur Lagesicherung für das Basisteil während des Anhebevorganges des Patienten und einer eventuellen Verschwenkung durch den Kranarm kann vorgesehen sein, daß das Basisteil mit ausfahrbaren oder ausziehbaren hydraulischen Stützen versehen ist.To stabilize and secure the position of the base part during the lifting process of the patient and a possible pivoting by the crane arm, it can be provided that the base part is provided with extendable or extendable hydraulic supports.

Selbstverständlich können im Rahmen der Erfindung auch mechanisch oder elektrisch betätigte Stützen vorgesehen sein.Of course, mechanically or electrically operated supports can also be provided within the scope of the invention.

Eine einfache Verbindung und Verschwenkbarkeit des Kranarmes mit dem Basisteil ist gegeben, wenn vorgesehen ist, daß der Kranarm gelenkig auf einer um eine vertikale Achse drehbaren und auf dem Basisteil angeordneten Platte befestigt ist.A simple connection and pivotability of the crane arm to the base part is provided if it is provided that the crane arm is articulated on a plate rotatable about a vertical axis and arranged on the base part.

Im allgemeinen wird ein einarmig frei auskragender Kranarm ausreichend sein. Damit neben der Verschwenkbarkeit um eine vertikale Achse auch die notwendige Höhenverstellbarkeit gegeben ist, kann vorgesehen sein, daß neben dem Kranarm ein Hydraulikzylinder gelenkig auf der Platte befestigt ist, während das vordere Ende des Kolbens des Hydraulikzylinders an dem Kranarm angreift.In general, a single-arm cantilever arm will be sufficient. So that in addition to the pivotability about a vertical axis and the necessary height adjustability is provided, it can be provided that in addition to the crane arm, a hydraulic cylinder is articulated on the plate, while the front end of the piston of the hydraulic cylinder engages the crane arm.

Durch ein entsprechendes Aus- und Einfahren des Kolbens läßt sich der Kranarm durch eine Änderung seiner Schrägstellung gegenüber der Vertikalachse in der Höhe verstellen, wenn er entsprechend mit einer schrägen Achse zur Vertikalen an der Platte gelenkig befestigt ist.By appropriately extending and retracting the piston the crane arm can be adjusted in height by changing its inclined position relative to the vertical axis if it is articulated on the plate with an inclined axis to the vertical.

In Weiterbildung der Erfindung kann vorgesehen sein, daß der Kranarm einen vorderen, in horizontaler Richtung abgewinkelten Hebearm aufweist, auf dem ein parallel zu dem Hebearm verlaufender Hydraulikzylinder angeordnet ist, an dessem Kolben eine Aufhängeeinrichtung für die Trageinrichtung befestigt ist.In a further development of the invention it can be provided that the crane arm has a front lifting arm which is angled in the horizontal direction, on which a hydraulic cylinder running parallel to the lifting arm is arranged, on the piston of which a suspension device for the carrying device is attached.

Durch den Hydraulikzylinder mit seinem Kolben sind auf diese Weise auch horizontale Ausgleichsbewegungen zur genauen Positionierung der Trageinrichtung möglich.The hydraulic cylinder with its piston also enables horizontal compensatory movements for precise positioning of the carrying device.

Durch ein Drehglied, das um eine vertikale Achse drehbar mit der Aufhängeeinrichtung verbunden ist bzw. ein Teil davon bildet, kann die Trageinrichtung ebenfalls exakt zu dem anzuhebenden Patienten positioniert werden.The support device can also be positioned exactly in relation to the patient to be lifted by means of a rotating member which is connected to the suspension device or forms part of it, so that it can rotate about a vertical axis.

Eine einfache Ausgestaltung der Trageinrichtung kann darin bestehen, daß sie zwei Greifarme aufweist, die jeweils mit Schienen versehen sind, von deren unteren Enden aus jeweils Auflageteile mit wenigstens annähernd horizontalen Achsen nach innen ragen.A simple embodiment of the support device can consist in that it has two gripping arms, each of which is provided with rails, the lower of which Protruding ends from support parts with at least approximately horizontal axes protrude inwards.

Durch eine gemeinsame Betätigung der beiden Greifarme läßt sich damit die Trageinrichtung auf einfache Weise öffnen und schließen, womit die anzuhebende Person ähnlich der Kinematik eines Baggers mit zwei seitlichen Schaufeln umfaßt werden kann.By a joint actuation of the two gripping arms, the carrying device can be opened and closed in a simple manner, whereby the person to be lifted can be encompassed with two side buckets similar to the kinematics of an excavator.

In Weiterbildung der Erfindung kann dabei vorgesehen sein, daß die Schienen auf jeder Seite an einem gemeinsamen horizontalen Träger angeordnet sind, an der eine hydraulische Verstelleinrichtung für eine Öffnungs- und Schließbewegung der beiden Greifarme angreift.In a further development of the invention it can be provided that the rails are arranged on each side on a common horizontal support on which a hydraulic adjusting device engages for an opening and closing movement of the two gripping arms.

Durch die beiden seitlichen Träger ist eine Zentraleinheit geschaffen, an der die hydraulische Verstelleinrichtung angreifen kann. Gleichzeitig können an dem Träger in einer gewünschte Reihenfolge und einem gewünschten Abstand entsprechend Schienen in Abhängigkeit von dem Anwendungsfall angeordnet werden.A central unit is created by the two side supports, on which the hydraulic adjustment device can engage. At the same time, rails can be arranged on the carrier in a desired order and a desired distance depending on the application.

Von Vorteil ist es dabei, wenn die Schienen an einer horizontalen Achse einstellbar mit dem Träger verbunden sind.It is advantageous if the rails are adjustably connected to the carrier on a horizontal axis.

Auf diese Weise können die Schienen an die jeweils anzuhebende Person optimal angepaßt werden, denn auf diese Weise sind Seitenbewegungen möglich, und die Auflageteile der Schienen können in Abhängigkeit von der Größe des Patienten exakt z.B. unter dem Knie, unter dem Gesäß und zum Beispiel am Hals positioniert werden.In this way, the rails can be optimally adapted to the person to be lifted, because lateral movements are possible in this way, and the support parts of the rails can, depending on the size of the patient, be exactly e.g. under the knee, under the buttocks and for example on the neck.

Von Vorteil ist es dabei, wenn weiterhin vorgesehen ist, daß die Schienen längenverstellbar sind.It is advantageous if it is further provided that the rails are adjustable in length.

Durch die Längenverstellbarkeit wird die Anpaßmöglichkeit an den Patienten noch weiter verbessert.The adjustability to the patient is further improved by the length adjustability.

Eine einfache Möglichkeit für eine Längenverstellbarkeit kann darin bestehen, daß die Schienen zweiteilig mit einem Oberteil, das an dem Träger gelenkig befestigt ist, und einem Unterteil, von dem aus die Auflageteile abzweigen, ausgebildet sind.A simple possibility for a length adjustability can consist in that the rails are formed in two parts with an upper part which is articulated to the carrier and a lower part from which the support parts branch off.

In einer Weiterbildung der Erfindung kann vorgesehen sein, daß die hydraulische Verstelleinrichtung lösbar mit den Trägern verbunden ist.In a development of the invention it can be provided that the hydraulic adjustment device is detachably connected to the carriers.

Durch eine Lösbarkeit zwischen der hydraulischen Verstelleinrichtung und den Trägern kann im Bedarfsfalle auch die gesamte Trageinrichtung ausgetauscht werden.Due to a detachability between the hydraulic adjustment device and the carriers can also be replaced if necessary, the entire support device.

So ist es z.B. möglich, statt horizontalen Trägern Träger vorzusehen, die abgewinkelt sind, wobei an jedem Schenkel der Winkelteile Schienen einstellbar befestigt sind.So it is e.g. possible instead of horizontal beams to provide beams that are angled, rails being adjustably attached to each leg of the angular parts.

Durch eine auf diese Weise ausgebildete Trageinrichtung können Patienten damit auch in einer sitzenden oder halbsitzenden Position angehoben und transportiert werden, was für diese bequemer ist, sofern der Gesundheits- oder Behindertenzustand diese Transportmöglichkeit zuläßt.By means of a carrying device designed in this way, patients can thus also be lifted and transported in a seated or semi-seated position, which is more convenient for them if the state of health or handicap allows this transport option.

Im allgemeinen werden vier auf Abstand nebeneinander angeordnete Schienen pro Träger auf jeder Seite ausreichend sein. Im Bedarfsfalle sind selbstverständlich jedoch auch mehr Schienen möglich, wobei man die Auflageteile der Schienen mit Polsterungen versehen kann, um an dem Patienten Druckstellen oder sogar Verletzungen zu vermeiden.In general, four spaced rails per beam on each side will be sufficient. If necessary, however, more rails are of course also possible, and the support parts of the rails can be provided with upholstery in order to avoid pressure points or even injuries on the patient.

Nachfolgend ist ein Ausführungsbeispiel der Erfindung anhand der Zeichnung prinzipmäßig beschrieben.An exemplary embodiment of the invention is described in principle with reference to the drawing.

Die Hebe- und Transportvorrichtung für Kranke oder physisch Behinderte, wozu auch Patienten mit Unfallverletzungen gehören, weist ein Basisteil 1 auf, das im wesentlichen ein fahrbares Gehäuse darstellt, welches mit zwei größeren angetriebenen Rädern 2 und ein oder zwei kleineren vorderen um eine vertikale Achse drehbaren Führungsrädern 3 versehen ist. Die beiden hinteren Räder 2 sind jeweils unabhängig voneinander von einem Motor 4 über einen Keilriemen und eine mit dem Rad 2 verbundenen Keilriemenscheibe 6 antreibbar.The lifting and transport device for the sick or physically handicapped, which also includes patients with accident injuries, has a base part 1, which essentially represents a mobile housing which can be rotated about a vertical axis with two larger driven wheels 2 and one or two smaller front wheels Guide wheels 3 is provided. The two rear wheels 2 can each be driven independently of one another by a motor 4 via a V-belt and a V-belt pulley 6 connected to the wheel 2.

Auf der Oberseite des Basisteiles 1 ist eine Drehplatte 7 angeordnet, die motorisch, z.B. über einen Hydraulikantrieb, um eine vertikale Achse drehbar ist. Auf der Drehscheibe 7 ist über ein Gelenk 8 ein Ende eines Kranarmes 9 schwenkbar befestigt. Auf Abstand davon ist über ein weiteres Gelenk 10 ein Hydraulikkolben 11 ebenfalls auf der Drehscheibe 7 befestigt. Das oben aus dem Hydraulikzylinder 11 ragende Ende des dazugehörigen Hydraulikkollbens 12 stützt sich an einer Konsole 13 des Kranarmes 9 ab. Oberhalb der Konsole 13 ist der Kranarm 9 mit einem in horizontaler Richtung abgewinkelten Hebeteil 14 versehen. Auf dem abgewinkelten Hebeteil 14 des Kranarmes 9 ist ein weiterer Hydraulikzylinder 15 angeordnet, dessen Hydraulikkolben 16 nach vorne herausragt. Je nach der Position des im allgemeinen schräg von der Drehscheibe 7 nach oben ragenden Kranarmes 9 wird sich der abgewinkelte Hebeteil 14 des Kranarmes 9 und damit auch der Hydraulikkolben 16 wenigstens annähernd in horizontaler Richtung erstrecken. Grundsätzlich kann der Kranarm 9 jedoch in Pfeilrichtung um das Gelenk 8 entsprechend der Verschiebemöglichkeit des Hydraulikkolbens 12 in Pfeilrichtung verschwenkbar sein. Auf diese Weise kann eine Trageinrichtung 17, die über eine Aufhängeeinrichtung 18 mit dem vorderen Ende des Hydraulikkolbens 16 und über eine Schubstange 19 mit dem abgewinkelten Hebeteil 14 des Kranarmes 9 verbunden ist, horizontal und vertikal positioniert werden.A rotary plate 7 is arranged on the upper side of the base part 1 and can be rotated about a vertical axis by a motor, for example via a hydraulic drive. On the turntable 7, one end of a crane arm 9 is pivotally attached via a joint 8. At a distance from this, a hydraulic piston 11 is also fastened to the turntable 7 via a further joint 10. The end of the associated hydraulic piston 12 protruding from the hydraulic cylinder 11 is supported on a bracket 13 of the crane arm 9. Above the console 13, the crane arm 9 is provided with a lifting part 14 which is angled in the horizontal direction. A further hydraulic cylinder 15 is arranged on the angled lifting part 14 of the crane arm 9, the hydraulic piston 16 of which protrudes forward. Depending on the position of the crane arm 9, which generally projects obliquely upward from the turntable 7, the angled lifting part 14 of the crane arm 9 and thus also the hydraulic piston 16 will extend at least approximately in the horizontal direction. Basically, however, the crane arm 9 can be pivoted in the direction of the arrow about the joint 8 in accordance with the possibility of displacement of the hydraulic piston 12 in the direction of the arrow. In this way, a support device 17, which is connected via a suspension device 18 to the front end of the Hydraulic piston 16 and is connected via a push rod 19 to the angled lifting part 14 of the crane arm 9, can be positioned horizontally and vertically.

Die Aufhängeeinrichtung 18 ist mit einem um eine vertikale Achse drehbaren Drehglied 20 versehen, das z.B. hydraulisch verdrehbar ist. Mit dem Drehglied 20 ist über ein Gestänge 21 jeweils seitlich ein Träger 22 verbunden. An den beiden Trägern 22, die sich in ihrer Grundposition in horizontaler Richtung erstrecken, sind nebeneinander und auf Abstand voneinander angeordnet jeweils vier Schienen 23 jeweils über einen Drehpunkt 31 mit ihren einen Enden gelenkig verbunden. Die gelenkige Verbindung kann jedoch durch eine Klemmeinrichtung (nicht dargestellt) bei Bedarf auch in einer gewünschten Lage fixiert werden. Hierzu können z.B. Klemmschrauben dienen. Die Schienen 23 sind jeweils zweiteilig ausgebildet, und zwar bestehen sie jeweils aus einem oberen Teil 23 und einem längeneinstellbar damit verbundenen unteren Teil 230. Die Längeneinstellbarkeit kann z.B. durch ein Langloch 24 erfolgen, das z.B. jeweils in dem oberen Teil der Schiene 23 angeordnet ist und über einen Gewindezapfen 25, der jeweils in dem unteren Teil 230 der Schiene 23 befestigt ist und durch eine Klemmschraube nach einer entsprechenden Positionierung in dem Langloch 24 entsprechend festgeklemmt wird. Auf diese Weise ist die Gesamtlänge jeder Schiene 23 einstellbar, und zwar individuell pro Schiene.The suspension device 18 is provided with a rotary member 20 which can be rotated about a vertical axis and which can be rotated hydraulically, for example. A carrier 22 is laterally connected to the rotary member 20 via a linkage 21. On the two supports 22, which extend in their basic position in the horizontal direction, four rails 23 are arranged next to one another and at a distance from one another, each having an articulated connection at one end via a pivot point 31. However, the articulated connection can also be fixed in a desired position by a clamping device (not shown) if required. For example, clamping screws can be used. The rails 23 are each formed in two parts, namely they each consist of an upper part 23 and a length-adjustable lower part 230. The length can be adjusted, for example, by an elongated hole 24, which is arranged, for example, in the upper part of the rail 23 and via a threaded pin 25 which is fastened in each case in the lower part 230 of the rail 23 and by a clamping screw after a corresponding positioning in the elongated hole 24 is clamped. In this way, the total length of each rail 23 can be adjusted, individually for each rail.

Von den unteren Teilen 230 der Schienen 23 erstrecken sich jeweils horizontale Auflageteile 26 nach innen, die in einfacher Weise durch eine entsprechende Umlenkung der unteren Teile 230 der Schienen gebildet sind und damit mit den Schienen einstückig sind. Jede Schiene 26 kann bei Bedarf mit einem Auflagepolster 27 versehen sein.Horizontal support parts 26 each extend inward from the lower parts 230 of the rails 23, which are formed in a simple manner by a corresponding deflection of the lower parts 230 of the rails and are therefore integral with the rails. Each rail 26 can be provided with a support pad 27 if necessary.

Bei dem in der Fig. 3 dargestellten Ausführungsbeispiel der Trageinrichtung 17 verlaufen die beiden Träger 22 linear und in Grundstellung in horizontaler Richtung, wobei bei einer entsprechenden Länge der Schienen 23 auch die daraus sich ergebende Auflagefläche für eine anzuhebende und zu transportierende Person auf den Auflageteilen 26 im wesentlichen horizontal verläuft.In the embodiment of the carrying device 17 shown in FIG. 3, the two carriers 22 run linearly and in the basic position in the horizontal direction, with the corresponding length of the rails 23 also the resulting bearing surface for a person to be lifted and transported on the bearing parts 26 runs essentially horizontally.

In der Fig. 4 ist eine Ausgestaltung einer Trageinrichtung 17 dargestellt, die für eine sitzende oder halbsitzende Position einer anzuhebenden Person geeignet ist. Grundsätzlich ist die Trageinrichtung jedoch in gleicher Weise aufgebaut wie die Trageinrichtung nach der Fig. 3. Der wesentliche Unterschied besteht lediglich darin, daß der Träger 22A nunmehr gegen die horizontale Richtung abgewinkelt ist. Bei einer entsprechenden Anordnung der Schienen 23 im wesentlichen jeweils vertikal zu der Längsrichtung der beiden Teile der Träger 22A ergibt sich somit auch eine gegenüber der horizontalen nach oben abgeknickte Auflagefläche für die anzuhebende Person und damit eine sitzende oder halbsitzende Anhebe- und Transportlage.FIG. 4 shows an embodiment of a carrying device 17 which is suitable for a seated or half-seated position of a person to be lifted. Basically, however, the support device is constructed in the same way as the support device 3. The essential difference is only that the carrier 22A is now angled against the horizontal direction. With a corresponding arrangement of the rails 23 essentially vertically to the longitudinal direction of the two parts of the brackets 22A, this also results in a support surface for the person to be lifted which is bent upwards relative to the horizontal and thus a seated or semi-seated lifting and transport position.

Im allgemeinen werden vier auf Abstand voneinander angeordnete Schienen ausreichend sein, wobei man die beiden äußeren jeweils als Auflagefläche für den Kopf bzw. Hals und den Kniebereich und die beiden inneren Schienen für den Gesäßbereich der anzuhebenden Person verwenden wird.In general, four spaced-apart rails will be sufficient, the two outer rails being used as support for the head or neck and the knee region and the two inner rails for the buttock region of the person to be lifted.

Zur Bedienungserleichterung und hauptsächlich auch deshalb, damit die Hebe- und Transportvorrichtung von einer Betreuungsperson alleine bedient werden kann, ist diese mit einer Fernsteuereinrichtung 28 versehen, die z.B. in dem Basisteil 1 angeordnet ist. Derartige Fernsteuereinrichtungen mit einem Empfangs- und einem Steuerteil sind allgemein bekannt, weshalb diese nachfolgend nicht mehr beschrieben werden. Die Fernsteuerung kann z.B. über Funk, über Infrarot, Ultraschall o.dgl. erfolgen. Selbstverständlich kann das Basisteil 1 jedoch auch mit einem entsprechenden Schaltpult zur direkten manuellen Bedienung versehen sein.To facilitate operation and mainly also so that the lifting and transporting device can be operated by one caregiver alone, this is provided with a remote control device 28, which is arranged, for example, in the base part 1. Such remote control devices with a receiving and a control part are generally known, which is why they are no longer described below. The remote control can for example via radio, infrared, ultrasound or the like. respectively. Of course, the base part 1 can also be provided with a corresponding control panel for direct manual operation.

Die Hebe- und Transportvorrichtung funktioniert auf folgende Weise:
Das Basisteil 1 wird durch eine entsprechende Steuerung der beiden Antriebsmotore 4 an die gewünschte Stelle, z.B. ein Bett mit einer darin liegenden Person, so weit wie möglich herangefahren. Anschließend fährt man die Hydraulikstützen 29 aus, damit das Basisteil 1 positioniert und gesichert ist. Durch eine entsprechende Verschwenkung des Kranarmes 9 sind noch horizontale und vertikale Anpaßeinstellungen der Trageinrichtung 17 möglich. Zusätzlich kann auch noch eine letzte Feineinstellung durch eine entsprechende Verstellung des Hydraulikkolbens 16 vorgenommen werden. Durch das Drehglied 20 kann die Trageinrichtung 17 mit den beiden Trägern 22 so über bzw. seitlich neben der anzuhebenden Person positioniert werden, daß die Träger 22 parallel zur Längsrichtung der liegenden Person verlaufen.The lifting and transport device works in the following way:
The base part 1 is moved as far as possible by appropriate control of the two drive motors 4 to the desired location, for example a bed with a person lying in it. The hydraulic supports 29 are then extended so that the base part 1 is positioned and secured. By appropriately pivoting the crane arm 9, horizontal and vertical adjustment settings of the carrying device 17 are still possible. In addition, a final fine adjustment can also be made by a corresponding adjustment of the hydraulic piston 16. By means of the rotary member 20, the support device 17 with the two supports 22 can be positioned above or to the side of the person to be lifted such that the supports 22 run parallel to the longitudinal direction of the person lying down.

Anschließend wird die Verstelleinrichtung mit dem Gestänge 21 derart betätigt, daß die horizontalen Auflageteile 26 einander so weit angenähert werden, daß sie die anzuhebende Person untergreifen. Die Wirkungsweise des Gestänges 21 entspricht z.B. der Wirkungsweise eines Baggers mit zwei Schaufeln und ist allgemein bekannt, weshalb nachfolgend nicht näher darauf eingegangen wird.Then the adjusting device is operated with the linkage 21 such that the horizontal support parts 26 are so close to each other that they reach under the person to be lifted. The mode of operation of the linkage 21 corresponds, for example, to the mode of operation of an excavator with two buckets and is generally known, which is why it will not be discussed in more detail below.

Anschließend kann durch eine entsprechende Hubbewegung des Kranarmes 9 durch ein Ausfahren des Hydraulikkolbens 12 die von der Trageinrichtung 17 erfaßte Person angehoben werden. Durch eine Betätigung der Drehscheibe 7 kann die angehobene Person dann in horizontaler Richtung beliebig verschwenkt werden, wobei durch eine Betätigung des Drehgliedes 20 auch Lageänderungen bezüglich der Längsrichtung der Person möglich werden, um diese z.B. richtig auf ein anderes Bett zu legen, das winklig zu dem ersten Bett steht. Durch eine entsprechend umgekehrte Bewegungsrichtung des Hydraulikkolbens 12, d.h. ein Einfahren in den Hydraulikzylinder 11, kann die Person dann an der gewünschten Stelle abgelegt werden. Anschließend wird die Trageinrichtung 17 durch ein Auseinanderfahren der Auflageteile 26 wieder geöffnet.The person gripped by the carrying device 17 can then be lifted by a corresponding lifting movement of the crane arm 9 by extending the hydraulic piston 12. By actuating the turntable 7, the lifted person can then be pivoted as desired in the horizontal direction, with actuation of the rotary member 20 also making changes in position with respect to the longitudinal direction of the person possible, e.g. properly put on another bed that is angled to the first bed. By a correspondingly reversed direction of movement of the hydraulic piston 12, i.e. retracting into the hydraulic cylinder 11, the person can then be placed at the desired location. The support device 17 is then opened again by moving the support parts 26 apart.

Falls die angehobene Person weiter transportiert werden soll, z.B. in einen Operationssaal oder ein anderes Zimmer, so ist dies mit der Hebe- und Transportvorrichtung ebenfalls möglich. Hierzu ist es lediglich erforderlich, die Hydraulikstützen 29 einzufahren und die beiden Antriebsmotore 4 für die Räder 2 entsprechend zu betätigen, womit die gesamte Einheit mit der in der Trageinrichtung 17 liegenden Person verfahren werden kann.If the person being lifted is to be transported further, for example to an operating room or another Room, this is also possible with the lifting and transport device. For this it is only necessary to retract the hydraulic supports 29 and to actuate the two drive motors 4 for the wheels 2 accordingly, with which the entire unit can be moved with the person lying in the carrying device 17.

Die für die Hydraulikmotoren erforderlichen Einrichtungen, wie z.B. eine Hydraulikpumpe, können im Basisteil 1 angeordnet werden, wobei im Inneren des Kranarmes 9 und dessen abgewinkelten Hebeteil 14 entsprechend verlaufende Hydraulikleitungen für eine Energieversorgung des Hydraulikkolbens 16 des Drehgliedes 18 und der Verstelleinrichtung 21 dienen. Für die elektrische oder elektronische Steuerung und Aktivierung der angetriebenen Teile können in dem Basisteil 1 eine Batterie oder ein Akku 30 zur Energieversorgung angeordnet sein.The equipment required for the hydraulic motors, e.g. a hydraulic pump, can be arranged in the base part 1, with correspondingly extending hydraulic lines in the interior of the crane arm 9 and its angled lifting part 14 serving to supply energy to the hydraulic piston 16 of the rotary member 18 and the adjusting device 21. A battery or rechargeable battery 30 for energy supply can be arranged in the base part 1 for the electrical or electronic control and activation of the driven parts.

Um die Trageinrichtung 17 bei Bedarf auswechseln zu können, z.B. um einen Austausch zwischen dem Ausführungsbeispiel nach der Fig. 3 oder der Fig. 4 vornehmen zu können, wird man die Verbindung des Gestänges 21 mit dem dazugehörigen hydraulischen Betätigungsteil 31 lösbar ausbilden.In order to be able to replace the carrying device 17 if necessary, e.g. In order to be able to carry out an exchange between the exemplary embodiment according to FIG. 3 or FIG. 4, the linkage of the linkage 21 with the associated hydraulic actuating part 31 will be detachable.
