Description

Einrichtung zum Heben bzw. Senken von Lasten, insbesondere von gebrechlichen oder behinderten Personen Device for lifting or lowering loads, especially for frail or disabled people
Beschreibungdescription
Die Erfindung betrifft eine Einrichtung zum Heben bzw. Senken von Lasten, insbesondere von gebrechlichen oder be¬ hinderten Personen, z.B. in Badewannen.The invention relates to a device for lifting or lowering loads, in particular of frail or disabled persons, e.g. in bathtubs.
Solche Einrichtungen sind bereits in verschiedener Form be¬ kannt. Sie weisen üblicherweise einen schwenkbaren Tragarm auf, der in der Nähe der Badewanne angeordnet wird. An die¬ sem Tragarm ist eine Sitzschlaufe vorgesehen, in welche die zu transportierende Person hineinzusetzen ist. Der Trag arm läßt sich dann über die Badewanne schwenken, so daß die Person zusammen mit der Sitzschlaufe in die Badewanne ab¬ gesenkt werden kann. Das Herausheben der Person aus der Badewanne erfolgt in entsprechender Weise. Eine derartige Einrichtung ist außerordentlich aufwendig, da das gesamte Gewicht der zu transportierenden Person aufgenommen und eine Schwenkbewegung durchgeführt werden muß. Außerdem er¬ fordert diese herkömmliche Einrichtung sehr viel Platz, damit der Schwenkbarm frei bewegt v/erden kann. Eine solche Kraneinrichtung ist insbesondere für Personen mit schwerste Behinderungen geeignet, z.B. solchen Personen, die völlig bewegungsunfähig sind und die eine Betreuungsperson benö- cjen.Such devices are already known in various forms. They usually have a pivoting support arm, which is arranged near the bathtub. A seat loop is provided on this support arm, into which the person to be transported is to be placed. The support arm can then be pivoted over the bathtub, so that the person can be lowered into the bathtub together with the seat loop. The person is lifted out of the bathtub in a corresponding manner. Such a device is extremely complex, since the entire weight of the person to be transported must be carried out and a pivoting movement must be carried out. In addition, this conventional device requires a lot of space so that the swivel arm can be moved freely. Such a crane device is particularly for people with the heaviest Disabilities suitable, for example, those who are completely unable to move and who need a caregiver.
Glücklicherweise ist die Behinderung von zahlreichen Perso¬ nen jedoch wesentlich geringer. Bei älteren oder korpulenten Personen besteht häufig lediglich die Schwierigkeit, sich in einer relativ .engen Badewanne- hinzusetzen und.sich nach dem Bad wieder aus der rutschigen Badewanne zu erheben. Die zuvor beschriebene Kraneinrichtung ist hier viel zu aufwendig.Fortunately, the disability of many people is much less. Older or obese people often only have the difficulty of sitting down in a relatively narrow bath tub and getting out of the slippery bath tub after the bath. The crane device described above is far too complex.
Die Aufgabe besteht nunmehr darin, in solchen Fällen für Ab¬ hilfe zu sorgen und eine Einrichtung anzugeben, die es bei ringem Bauaufwand1 und Platzbedarf bei geringen Kosten er- möglicht, daß sich behinderte oder gebrechliche Personen in eine Badewanne setzen und diese auch wieder aus eigener Kraft verlassen können.The task now is to provide remedial action in such cases and to provide a device which, with a small amount of construction 1 and space requirements at a low cost, enables disabled or frail persons to sit in a bathtub and remove it again can leave on their own.
Erfindungsgemäß ist eine solche Einrichtung dadurch gekenn- zeichnet, daß auf einem teleskopartig ein- und ausfahrbaren, etwa senkrecht stehenden Rohr ein Sitzbrett für die behinder¬ te JPer-sonen vorgesehen ist. Die Einrichtung läßt sich inner¬ halb der Badewanne abstellen, so daß der Platzbedarf außer¬ ordentlich gering ist. Außerhalb der Badewanne ist zusätz- licher Raum nicht erforderlich. Die Einrichtung ist außerdem sehr sicher, da der Sitz innerhalb der Badewanne angeordnet ist und damit Stürze ausgeschlossen werden können.According to the invention, such a device is characterized in that a seat board for the handicapped person is provided on a telescopically retractable and approximately vertical tube. The device can be parked inside the bathtub, so that the space requirement is extremely small. No additional space is required outside the bathtub. The device is also very safe because the seat is located inside the bathtub and falls can be excluded.
Das teleskopartige Rohr kann eine hydraulisch betriebene Zylindereinheit sein. Zusätzliche Hebeeinrichtungen, z.B.The telescopic tube can be a hydraulically operated cylinder unit. Additional lifting devices, e.g.
Seilzüge oder dergleichen sind nicht mehr erforderlich. Das teleskopierbare Rohr wird dabei mindestens zwei, gegebenen¬ falls auch mehr ineinander angeordnete und gegeneinander ver¬ schiebbare Rohrabschnitte aufweisen. Dadurch ist es möglich, die Höhe im zusammengeschobenen Zustand sehr gering zu halten, so daß ein sehr weitgehendes Absenken möglich ist. Die jeweilige Person kann dabei während des Bades auf der Einrichtung sitzen bleiben, was das Baden erleichtert. Ein Verlassen der Einrichtung, das unter Umständen Schwierig¬ keiten bereitet, ist nicht mehr erforderlich. Zwischen den Rohrabschnitten können Dichtelemente vorgesehen sein, die sicherstellen, daß das hydraulische Druckmittel nicht aus dem Rohr heraustreten kann.Cables or the like are no longer required. The telescopic tube will have at least two, possibly also more nested and mutually displaceable tube sections. This makes it possible to keep the height very low when pushed together, so that a very extensive lowering is possible. The respective person can be on the Furnishings stay in place, which makes bathing easier. Leaving the facility, which may cause difficulties, is no longer necessary. Sealing elements can be provided between the pipe sections, which ensure that the hydraulic pressure medium cannot emerge from the pipe.
Als Hydraulikmittel kann vorzugsweise Wasser Verwendung finden. Wasser läßt sich nämlich sehr leicht handhaben, insbesondere in einer Badewanne, in der ohnehin mit Wasser gearbeitet wird. Unbeabsichtigt austretendes Wasser kann dabei keinerlei Schaden anrichten, und ein spezielles Hy- draulikfluid, z.B. Öl, ist nicht erforderlich, obwohl es selbstverständlich im Bedarfsfall ebenfalls eingesetzt werden könnte. Das teleskopartige Rohr kann über eine An¬ schlußleitung an ein ohnehin vorhandenes Wasserleitungsnetz angeschlossen werden. Der Druck innerhalb des Wasserleitungs¬ netzes ist ausreichend, um den Sitz mit einer darauf sitzen¬ den Person zu heben, ohne daß dabei zusätzliche Pumpen oder Motoren erforderlich sind.Water can preferably be used as the hydraulic medium. Water is very easy to handle, especially in a bathtub in which water is used anyway. Unintentionally escaping water cannot cause any damage, and a special hydraulic fluid, e.g. Oil is not necessary, although it could of course also be used if necessary. The telescopic pipe can be connected via a connecting line to an already existing water supply network. The pressure within the water supply network is sufficient to lift the seat with a person sitting on it, without the need for additional pumps or motors.
Der Bauaufwand wird dadurch außerordentlich gering gehalten, da spezielle Antriebsvorrichtungen unnötig sind. Darüber hinaus ist das Wasserleitungsnetz in der Nähe einer Badewanne sehr leicht zugänglich, da hier Wasserhähne und ähnlicheThe construction effort is kept extremely low, since special drive devices are unnecessary. In addition, the water supply network near a bathtub is very easy to access, since there are taps and the like
Einrichtungen vorhanden sind, an die sich die Anschlußleitung sehr leicht anschließen läßt, z.B. die flexible Leitung für eine Handbrause.Facilities are available to which the connecting line can be connected very easily, e.g. the flexible pipe for a hand shower.
Die Steuerung der Einrichtung erfolgt dabei über ein in der Anschlußleitung vorgesehenes Mehrwegeventil. Ein solches Mehrwegeventil vereinfacht die Steuerung, da zum Heben le¬ diglich die Wasserzuleitung zu öffnen ist, der Wasserdruck dann das teleskopartige Rohr ausfährt und das Brett mit der darauf sitzenden Person anhebt. Zum Absenken ist dann le¬ diglich die Zuleitung über das Mehrwegeventil zu öffnen, so daß das Wasser aus dem teleskopartigen Rohr in die Badewanne ablaufen kann. Ein geschlossener Kreislauf für das Druck- fluid ist nicht erforderlich, was den Bauaufwand weiter ver_rin.ger .The device is controlled via a multi-way valve provided in the connecting line. Such a multi-way valve simplifies the control, since only the water supply line has to be opened for lifting, the water pressure then extends the telescopic tube and the board with the person sitting on it lifts. For lowering, the supply line then only has to be opened via the multi-way valve, so that the water from the telescopic tube into the bathtub can expire. A closed circuit for the pressure fluid is not necessary, which further reduces construction costs.
An dem, dem Sitzbrett gegenüberliegenden unteren Ende des teleskopartigen Rohres oder einer daran angebrachten Basis¬ platte geeigneter Form können höhenverstellbare StützfüBe vorgesehen sein. Mit solchen Stützfußen lassen sich Rundun¬ gen innerhalb der Badewanne leicht ausgleichen, so daß die Einrichtung einen festen und sicheren Stand aufweist.At the opposite, the seat board lower end of the telescopic tube or an attached base plate ¬ a suitable form may be provided height-adjustable StützfüBe. With such support Fussen is Rundun ¬ gen can compensate so that the device has a safe and secure position within the tub easily.
Die Rohrabschnitte können aus Kunststoff bestehen, so daß sie leicht herzustellen und leicht zu pflegen sind. Das Si-tzbπett kann .dabei austauschbar auf dem teleskopartigen Rohr befestigt sein. Die Einrichtung läßt sich auf dieseThe pipe sections can be made of plastic, so that they are easy to manufacture and easy to maintain. The Si-tzbπett can be.

Die Einrichtung zum Heben und Senken weist gemäß Fig. 1 ein teleskopartig ausgebildes Rohr 1 auf. Es setzt sich aus mehreren, zweckmäßigerweise zylindrischen Rohrabschnitten 2 von unterschiedlichem Durchmesser zusammen, welche inein¬ anderschiebbar sind. Das obere Ende des jeweiligen Rohrab¬ schnittes .2 ist dabei mit einem radial nach innen vorstehen- den Rand 3 versehen, z.B. einem Ringflansch, der mit einem radial nach außen überstehenden, komplementären Rand 4, zweckmäßigerweise auch einem Ringflansch, am unteren Ende des jeweiligen Rohrabschnittes 2 zusammenarbeitet. Diese Ränder 3 und 4 begrenzen die Bewegungsmöglichkeiten der in- einandergesteckten Rohrabschnitte 2, insbesondere beim Aus¬ fahren des teleskopartigen Rohres 1.1, the device for lifting and lowering has a telescopic tube 1. It exposes itself several, expediently cylindrical pipe sections 2 of different diameters, which can be pushed into one another. The upper end of the respective pipe section . 2 is provided with a radially inwardly projecting edge 3, for example an annular flange, which cooperates with a complementary edge 4 projecting radially outwards, expediently also an annular flange, at the lower end of the respective pipe section 2. These edges 3 and 4 limit the possibilities of movement of the nested pipe sections 2, in particular when the telescopic pipe 1 is extended.
Die Ränder 3 und 4 bilden gegenseitige Anschläge beim Aus¬ fahren der Rohrabschnitte 2, im eingefahrenen Zustand ge- maß Fig. 4 stützen sich die Ränder 3 und 4 in radialer Rich¬ tung oben und unten aneinander ab, so daß die Einrichtung eine gute Standfähigkeit hat.The edges 3 and 4 form mutual stops when the tube sections 2 are extended, in the retracted state according to FIG. 4 the edges 3 and 4 are supported against one another in the radial direction at the top and bottom, so that the device has good stability Has.
Der Rohrabschnitt 2 mit dem größten Durchmesser, der zugleich der unterste Abschnitt ist, ist auf seiner Unterseite durch einen Boden 5 verschlossen. Im innersten Rohrabschnitt 2 ist ein verschiebbarer Kolben 6 geführt, der am unteren Rand eine nach außen überstehende Schulter 12 aufweist, die mit dem Rand 3 des innersten Rohrabschnittes 2 zusammenarbeitet. Im Inneren des Rohres 1 ist auf diese Weise ein geschlosse¬ ner Raum gebildet, dessen Volumen veränderbar ist. Am Kol^ ben 6 ist oben eine Sitzplatte 7 vorgesehen, deren Verbin¬ dung lösbar ausgebildet sein kann.The tube section 2 with the largest diameter, which is also the lowest section, is closed by a bottom 5 on its underside. In the innermost pipe section 2, a displaceable piston 6 is guided, which has an outwardly projecting shoulder 12 on the lower edge, which cooperates with the edge 3 of the innermost pipe section 2. In this way, a closed space is formed in the interior of the tube 1, the volume of which can be changed. At the top of the piston 6, a seat plate 7 is provided, the connection of which can be detachable.
Am oberen Rand 3 und/oder am unteren Rand 4 bzw. der Schul¬ ter 12 können Dichtelemente 13 bzw. 14 beispielsweise in Form von Dichtringen vorgesehen bzw. eingebettet sein, wie es schematisc in Fig. 1 bzw. Fig. 4 angedeutet ist; sofern die Rohrabschnitte 2 glatt und bündig ineinander passen, können derartige Dichtelemente gegebenenfalls auch entfallen. Am unteren Rohrabschnitt 2 ist eine Anschlußleitung 8 ange¬ schlossen, durch welche das hydraulische Druckmittel, im vorliegenden Falle.vorzugsweise Wasser, in den Innenraum des Rohres 1 geleitet wird. Diese Anschlußleitung 8 ist da- zu an das Wasserleitungsnetz anschließbar, was im einzelnen nicht gezeigt ist. Hierzu können bekannte Schraub- oder Steckanschlüsse Verwendung finden. In der Anschlußleitung 8 ist ein Mehrwegeventil 9 vorgesehen, mit welchem, sich das Aus- bzw. Einfahren des teleskopartigen Rohres 1 sehr leicht steuern läßt. Verschiedene Stellungen dieses Mehrwegeven- tiles 9 sind in den Fig. 1, 2 und 3 dargestellt.At the upper edge 3 and / or at the lower edge 4 or the shoulder 12, sealing elements 13 or 14 can be provided or embedded, for example in the form of sealing rings, as is schematically indicated in FIG. 1 or FIG. 4; if the pipe sections 2 fit smoothly and flush into one another, such sealing elements may also be omitted. At the lower tube portion 2 is a connection line 8 is closed ¬ through which the hydraulic pressure medium, is guided in the present Falle.vorzugsweise water into the interior of the pipe. 1 This connecting line 8 can therefore be connected to the water supply network, which is not shown in detail. Known screw or plug connections can be used for this. In the connecting line 8, a multi-way valve 9 is provided, with which the extension or retraction of the telescopic tube 1 can be controlled very easily. Different positions of this reusable valve 9 are shown in FIGS. 1, 2 and 3.
Bei dem Mehrwegeventil 9 handelt es sich im vorliegenden Falle .um ein Dxeiwegeventil, das außen an die Anschlußlei- tung 8 an eine offene Leitung 10 angeschlossen ist. In der Position gemäß Fig. 1 ist das Mehrwegeventil 9 nach allen Seiten hin offen. Zum Ausfahren des teleskopartigen Rohres 1 ist das Mehrwegeventil 9 in die Stellung gemäß Fig. 2 zu bringen. Zusätzlich ist ein Wasserhahn im Wasserleitungs- netz zu öffnen. Das Wasser tritt dann durch das Mehrwege¬ ventil 9 in den Innenraum des Rohres 1 ein, so daß es aus¬ gefahren wird, bis es schließlich in die Position gemäß Pig. 1 gelangt. 'Der Wasserdruck -"ist dabei ausreichend, um eine auf dem Sitzbrett 7 befindliche Person mit anzuheben. Das Mehrwegeventil 9 und der Wasserhahn können dann abge¬ sperrt werden, so daß die Einrichtung in dieser Position beharrt.In the present case, the multi-way valve 9 is a double-way valve which is connected to the outside of the connecting line 8 to an open line 10. In the position shown in FIG. 1, the multi-way valve 9 is open on all sides. To extend the telescopic tube 1, the multi-way valve 9 is to be brought into the position shown in FIG. 2. In addition, a tap in the water supply network must be opened. The water then enters through the multi-way valve 9 into the interior of the tube 1, so that it is extended until it finally reaches the position according to Pig. 1 arrives. The water pressure is sufficient to lift a person on the seat board 7. The multi-way valve 9 and the water tap can then be shut off so that the device remains in this position.
Soll -die Einrichtung nunmehr abgesenkt werden, ist das Mehr- Wegeventil 9 in die Stellung gemäß Fig. 3 zu bringen. Durch das Eigengewicht des Rohres 1 und zusätzlich durch das Ge¬ wicht einer gegebenenfalls darauf sitzenden Person kann nun¬ mehr das im Innenraum des teleskopartigen Rohres 1 befind¬ liche Wasser über- die Anschlußleitung 8 und die Leitung 10 ins Freie bzw. die Badewanne gedrückt werden. Das Rohr 1 schiebt sich dabei zusammen, bis schließlich die Stellung gemäß Fig. 4 erreicht ist. Am unteren Rohrabschnitt 2 bzw. einer daran angebrachtenIf the device is now to be lowered, the multi-way valve 9 is to be brought into the position according to FIG. 3. Because of the weight of the tube 1 and additionally because of the weight of a person who may be sitting thereon, the water in the interior of the telescopic tube 1 can now be pressed out into the open or the bathtub via the connecting line 8 and the line 10 . The tube 1 pushes together until finally the position shown in FIG. 4 is reached. Attached to the lower pipe section 2 or one
Stützplatte bzw. einem außen anschließenden Stützring sind mehrere höhenverstellbare Stützfüße 11 vorgesehen, die es ermöglichen, die Einrichtung in einer Badewanne horizontal abzustellen und damit das teleskopierbare Rohr 1 wirklich senkrecht aufzurichten. Die Standfestigkeit wird dadurch wesentlich erhöht, da üblicherweise der Wannenboden leicht gewölbt ausgebildet ist.Support plate or an adjoining support ring, several height-adjustable support feet 11 are provided, which make it possible to place the device horizontally in a bathtub and thus to raise the telescopic tube 1 really vertically. The stability is significantly increased, since the tub floor is usually slightly arched.
Das Rohr 1 bzw. die Rohrabschnitte 2 können aus Kunststoff gefertigt sein. Die Einrichtung ist auf diese Weise sehr leicht bei hoher Festigkeit und außerdem korrosionsbeständig Zusätzlich oder alternativ können auch Dichtringe 15 in den radial außen liegenden Wänden der unteren Ränder 4 eingelegt sein und für die Abdichtung am anliegenden Rohrabschnitt 2 sorgen. Darüber hinaus kann die Sitzplatte 7 austauschbar und drehbar angeordnet sein, so daß sie sich den jeweiligen Erfordernissen anpassen läßt bzw. gegen eine entsprechende, anders geformte Sitzplatte 7, gegebenenfalls mit Lehne, austauschen läßt. Da das teleskopartige Rohr 1 aus mehreren Rohrabschnitten 2 aufgebaut ist, läßt sich die Einrichtung auf eine außerordentlich geringe Höhe zusammenschieben. Dies ist von besonderer Bedeutung, da die zu badende Person in der Wanne auf der Einrichtung sitzenbleiben kann, was eine wesentliche Erleichterung darstellt. Zusatzeinrichtungen wie Pumpen, Motoren oder dergleichen sind nicht weiter er¬ forderlich. Im Bedarfsfall kann die Einrichtung auch pneu¬ matisch betrieben werden, wobei der Aufbau grundsätzlich beibehalten werden kann; es ist lediglich auf eine ent- sprechende Abdichtung des Innenraumes des Rohres zu achten. The tube 1 or the tube sections 2 can be made of plastic. The device is very light in this way with high strength and is also corrosion-resistant. Additionally or alternatively, sealing rings 15 can also be inserted in the radially outer walls of the lower edges 4 and ensure the sealing on the adjacent pipe section 2. In addition, the seat plate 7 can be arranged interchangeably and rotatably, so that it can be adapted to the respective requirements or can be exchanged for a corresponding, differently shaped seat plate 7, optionally with a backrest. Since the telescopic tube 1 is constructed from several tube sections 2, the device can be pushed together to an extremely low height. This is of particular importance since the person to be bathed can remain seated in the tub on the device, which is a significant relief. Additional devices such as pumps, motors or the like are no longer required. If necessary, the device can also be operated pneumatically, whereby the structure can in principle be retained; it is only necessary to ensure that the interior of the pipe is properly sealed.
