Abstract

The chassis (1) of the lift comprises a frame (5) for mounting purposes for example against a wall, and a second frame (6) articulated to the first frame. The transport apparatus (2), for example a rigid sliding support (15) secured to a device (23) capable of carrying a person, and the drive machine (21) for raising and lowering the transport apparatus (2) are arranged on the second frame (6). To balance the load, a pneumatic spring (22) is provided which maintains the sliding support (15) to the second frame (6). Thus, only part of the required drive force has to be provided by a drive machine of reduced size. For the pivoting, only hinges (12) are needed. They may be arranged at a height at a distance independent of the height of the support and beyond that distance, thereby reducing the forces of friction and of support at rest.

Description

Badelift für Körperbehinderte Bath lift for the physically handicapped
Die vorliegende Erfindung betrifft einen Badelift für Kör¬ perbehinderte mit einem Transportgerät, das an einem Ge¬ stell lotrecht verschiebbar und seitlich schwenkbar ange¬ ordnet und durch eine Antriebsmaschine heb- und senkbar ist.The present invention relates to a bath lift for physically handicapped persons with a transport device which is arranged vertically displaceably on a stand and can be pivoted sideways and can be raised and lowered by a drive machine.
Stand der TechnikState of the art
Badelifte dieser Art sind in verschiedenen Ausführungen bekannt (z.B. US-PS 3.914.808, DE-OS 2.714.358, CH-PS 570 937). Das Gestell solcher Badelifte besteht aus einer teleskopartig ausfahrbaren Säule, in welcher die Antriebs¬ maschine in Form eines hydraulisch betriebenen Arbeits¬ zylinders eingeschlossen ist. Allen derartigen Ausfüh¬ rungen ist der Nachteil gemeinsam, dass die Antriebsvor- richtung die ganze Belastung durch das beladene Trans¬ portgerät zu tragen hat oder in Verbindung mit einer Kraftübersetzung einen übermässig langen Arbeitshub haben muss. In beiden Fällen führt dies zu verhältnismässig massiven, schweren und entsprechend teuren Hebevorrich- tungen mit zum Teil grosser Bauhöhe.Bath lifts of this type are known in various designs (e.g. US-PS 3,914,808, DE-OS 2,714,358, CH-PS 570 937). The frame of such bath lifts consists of a telescopically extendable column in which the drive machine is enclosed in the form of a hydraulically operated working cylinder. All such designs have the disadvantage in common that the drive device must bear the entire load from the loaded transport device or, in conjunction with a power transmission, must have an excessively long working stroke. In both cases, this leads to relatively massive, heavy and correspondingly expensive lifting devices, some of which have a large overall height.
Die Schwenklagerung des Transportgerätes bietet bei sol-" chen Konstruktionen zudem besondere Schwierigkeiten. Um eine leichtgängige Schwenklagerung zu erreichen, ist auf möglichst geringe Lagerkräfte zu achten. Dieses Problem ist bei den bekannten Hebevorrichtungen ebenfalls nicht be¬ friedigend gelöst. ■ Die Ausführung nach der US-PS 3.914.808 ermöglicht das Schwenken des Transportgerätes durch dreh¬ bare Lagerung der Säule an deren Basis, was bedeutet, dass das ganze Gewicht des belasteten Badelifts und das Kipp¬ moment von dieser Säulenlagerung aufgenommen werden muss. Demgegenüber ist bei der Ausführung nach der DE-OS 2.714.358 das Transportgerät mit einer Hülse am Umfang des vertikal beweglichen Teils der Säule schwenkbar gelagert, wobei die achsiale Länge der Hülse nur einen BruchteilThe pivotal mounting of the transport device has at sol "chen constructions also special difficulties. In order to achieve a smooth swivel bearing, pay attention to the smallest possible bearing forces. This problem is also not be¬ resolved satisfactorily in the known lifting devices. ■ The execution after the US PS 3.914.808 enables the transport device to be pivoted by pivoting the column at its base, which means that the entire weight of the loaded bath lift and the tilting moment must be absorbed by this column bearing DE-OS 2.714.358 the transport device with a sleeve on the circumference of the vertically movable part of the column is pivotally mounted, the axial length of the sleeve only a fraction

Aehnliche Verhält¬ nisse liegen vor im Falle der Ausführung nach der CH-PS 570 937, bei der das Transportgerät mit dem oberen Ende einer drehbaren Kolbenstange der Antriebsmaschine verbun- den ist, wobei die Kolbenstange im ausgefahrenen Zustand nur auf einem Bruchteil ihrer Länge geführt ist. In jedem dieser Fälle ist also mit verhältnismässig hohen Lagerkräf¬ ten und dementsprechend hohen Reibungskräften zu rechnen. Derartige Schwenklager stellen hohe Anforderungen hinsicht- lieh Präzision, sind gross und schwer und dementsprechend aufwendig in der Herstellung.0MP1> the length of this column part. Similar conditions exist in the case of the version according to CH-PS 570 937, in which the transport device is connected to the upper end of a rotatable piston rod of the drive machine, the piston rod being guided only over a fraction of its length in the extended state . In each of these cases, relatively high bearing forces and, accordingly, high frictional forces are to be expected. Such swivel bearings make high demands with regard to precision, are large and heavy and are accordingly complex to manufacture.
Aufgabe der Erfindung ist die Schaffung eines Badelifts, der unter Vermeidung der vorerwähnten Nachteile nur einen Bruchteil der bisher erforderlichen Antriebskraft benötigt und dadurch eine kompaktere und weniger aufwendige Bauart ermöglicht. Weiter ist mit der Erfindung eine Herabset¬ zung der Lagerkräfte in der Schwenklagerung des Transport¬ gerätes beabsichtigt, um einfachere und weniger aufwendige Schwenklager anwenden zu können.The object of the invention is to provide a bath lift which, while avoiding the aforementioned disadvantages, requires only a fraction of the previously required driving force and thereby enables a more compact and less complex design. Furthermore, the invention intends to reduce the bearing forces in the pivot bearing of the transport device in order to be able to use simpler and less complex pivot bearings.
Die Erfindung löst diese Aufgabe dadurch, dass das Trans¬ portgerät und die Antriebsmaschine an einem schwenkbaren Gestellteil angeordnet sind und dass das Transportgerät durch eine dem Lastausgleich dienende Gasfederanordnung am schwenkbaren Gestellteil abgestützt ist.The invention achieves this object in that the transport device and the drive machine are arranged on a pivotable frame part and in that the transport device is supported on the pivotable frame part by a gas spring arrangement serving for load balancing.
Die Gasfederanordnung nimmt in jeder Höhenlage des Trans¬ portgerätes den grössten Teil der Last auf, so dass die Antriebsmaschine nur für die geringe Restkraft zum Anhe¬ ben des Transportgerätes dimensioniert zu werden braucht. Das geringe Mass der benötigten Stellkraft rührt vor allem daher, dass sich die von einer Gasfeder ausgeübte Gegen¬ kraft über den ganzen Federweg nur wenig ändert.The gas spring arrangement absorbs most of the load at any height of the transport device, so that the drive machine need only be dimensioned for the low residual force for lifting the transport device. The small amount of actuating force required stems above all from the fact that the counterforce exerted by a gas spring changes only slightly over the entire spring travel.
Die verringerte Baugrösse der Antriebsmaschine ermöglicht es, insbesondere bei Verwendung hydraulisch oder pneuma¬ tisch betriebener Arbeitszylinder, für diese wie auch für die Gasfedern handelsübliche Bauformen einzusetzen. Eine solche Lösung benötigt daher im Gegensatz zu den bekannten Ausführungen keine besondere Konstruktion der Antriebs¬ mittel.The reduced size of the drive machine makes it possible, especially when using hydraulically or pneumatically operated working cylinders, for these as well as for use the gas springs commercially available designs. In contrast to the known designs, such a solution therefore does not require any special construction of the drive means.
Es ist zwar aus der DE-AS 2.730.305 bekannt, bei einem Badelift durch Federn einen Lastausgleich zu erzielen. Da¬ bei handelt es sich jedoch um mechanische Federn an einem von Hand anzuhebenden Transportgerät. Gegen Ende des Hubes ist die Federkraft nurmehr gering, so dass in diesem Be¬ reich fast die volle Kraft zum Anheben der Last vom Benut¬ zer aufgebracht werden muss.It is known from DE-AS 2.730.305 to achieve a load balance by springs in a bath lift. However, this involves mechanical springs on a transport device that can be lifted by hand. Towards the end of the stroke, the spring force is only slight, so that in this area almost the full force for lifting the load must be applied by the user.
Gasfedern für den Lastausgleich sind bereits in zahlreichen Anwendungsformen bekannt. Sie haben in vielen Fällen zu grundlegend neuen Konstruktionen von Bewegungsapparaten ge¬ führt. Im Falle ihres Einsatzes beim erfindungsgemässen Badelift bieten sie unter anderem die Möglichkeit zu einer Vereinfachung der Schwenklagerung des Transportgerätes.. Eine bevorzugte Ausführungsform der Erfindung besteht näm¬ lich darin, dass das Gestell aus einem feststehenden Mon¬ tagerahmen und einem mit diesem gelenkig verbundenen Schwenkrahmen besteht und dass das Transportgerät einen an zwei am Schwenkrahmen vorgesehenen lotrechten Führungs- stangen gelagerten Schlitten aufweist, an dem eine Perso- nentragvorrichtung befestigt ist. Dabei ist der Montage¬ rahmen vorzugsweise mindestens so hoch wie der Schwenkrah¬ men, so dass am unteren und oberen Ende des Schwenkrahmens Gelenkverbindungen vorgesehen werden können. Dadurch lässt sich die ganze durch den erforderlichen Schlittenhub be¬ dingte Gestellhöhe für die Plazierung der Schwenklager aus¬ nutzen, so dass die Lagerkräfte auf ein Minimum reduziert werden und trotz des zusätzlichen Gewichts der am Schwenk¬ rahmen befindlichen Antriebsmittel geringer ausfallen als bei herkömmlichen Lösungen, da das Gewicht der Antriebs¬ mittel nur einen Bruchteil des Gesamtgewichts des be¬ lasteten Transportgerätes ausmacht. Befänden sich die Antriebsmittel und der Schlitten am Montagerahmen und die Schwenklager für das Transportgerät am Schlitten, so würde bei gleicher Gestellhöhe nur die geringere Schlittenhöhe für die Schwenklagerung verfügbar sein, was höhere Lager- kräfte zur Folge hätte.Gas springs for load balancing are already known in numerous application forms. In many cases they have led to fundamentally new designs of musculoskeletal systems. If they are used in the bath lift according to the invention, they offer, among other things, the possibility of simplifying the swivel mounting of the transport device. A preferred embodiment of the invention consists in the fact that the frame consists of a fixed mounting frame and a swivel frame connected to it in an articulated manner and that the transport device has a carriage mounted on two vertical guide rods provided on the swivel frame, to which a person carrying device is attached. The mounting frame is preferably at least as high as the swivel frame, so that articulated connections can be provided at the lower and upper ends of the swivel frame. As a result, the entire frame height due to the required slide stroke can be used for the placement of the swivel bearings, so that the bearing forces are reduced to a minimum and, despite the additional weight of the drive means located on the swivel frame, are lower than in conventional solutions. since the weight of the drive means makes up only a fraction of the total weight of the loaded transport device. If they were Drive means and the slide on the mounting frame and the swivel bearings for the transport device on the slide, so with the same frame height only the lower slide height would be available for the swivel bearing, which would result in higher bearing forces.

Der gezeigte Badelift umfasst ein Gestell 1, an dem ein Transportgerät 2 lotrecht verschiebbar und seitlich schwenkbar angeordnet und durch eine Antriebsmaschine 3 heb- und senkbar ist.The bath lift shown comprises a frame 1, on which a transport device 2 is vertically displaceable and laterally pivotable and can be raised and lowered by a drive machine 3.
Das Gestell besteht aus einem an einer Wand 4' befestig¬ baren Montagerahmen 5 und einem mit diesem gelenkig ver¬ bundenen Schwenkrahmen 6. Die beiden Rahmen 5, 6 sind im Aufriss gleich gross und beispielsweise aus Seitentei¬ len 7 bzw. 8 und Stirnplatten 9 bzw. 10 zusammengesetzt, z.B. durch Schweissen. Als Seitenteile 7, 8 werden vor¬ zugsweise U-förmige Abkantprofilstücke verwendet. Zur Verstärkung und Wandbefestigung des Montagerahmens 5 sind dessen Seitenteile 7 ausserdem durch Traversen 11 verbun¬ den. Je ein Scharnier 12 am oberen und unteren Ende des Gestells bilden die Gelenkverbindung zwischen Schwenk- rahmen 6 und Montagerahmen 5, wobei der Schwenkrahmen je einen Schwenkarm 13 aufweist, der an einem auf der be¬ treffenden oberen bzw. unteren Stirnplatte 9 sitzenden Schwenkbolzen 14 gelagert ist. Vorzugsweise sind solche Schwenkarme 13 und Lagerbohrungen für die Aufnahme der Schwenkbolzen 14 auf beiden Gestellseiten vorgesehen, so dass bei der Montage des Badelifts die Schwenklagerung wahlweise auf der linken oder rechten Gestellseite einge¬ richtet und somit das Transportgerät den baulichen Verhält¬ nissen entsprechend nach links oder rechts ausgeschwenkt werden kann.The frame consists of a mounting frame 5 which can be fastened to a wall 4 ' and a swivel frame 6 which is connected to it in an articulated manner. The two frames 5, 6 are of equal size in elevation and, for example, from side parts 7 or 8 and end plates 9 or 10 assembled, for example by welding. U-shaped folding profile pieces are preferably used as side parts 7, 8. For reinforcement and wall mounting of the mounting frame 5, the side parts 7 are also connected by cross members 11. One hinge 12 each at the upper and lower ends of the frame form the articulated connection between the swivel frame 6 and mounting frame 5, the pivot frame each having a pivot arm 13 which is mounted on a pivot pin 14 seated on the relevant upper and lower end plate 9. Such swivel arms 13 and bearing bores are preferably provided for receiving the swivel pins 14 on both sides of the frame, so that when the bath lift is installed, the swivel mounting is set up either on the left or right side of the frame, and the transport device thus moves to the left or to the structural conditions can be swung out to the right.
Das Transportgerät 2 weist einen Schlitten 15 auf, der an zwei lotrechten, in den Stirnplatten 10 des Schwenkrahmens 6 verankerten Führungsstangen 16 gelagert ist. Der Schlit- ten 15 besitzt zwei Lagerbalken 17, die an den Lagerstellen vorzugsweise mit Kugelbüchsen 18 ausgerüstet sind. Zwei vertikale Stege 19 verbinden die beiden Lagerbalken 17 mit¬ einander und sind an ihrem oberen Ende durch eine Stütz¬ platte 20 gegenseitig verbunden.The transport device 2 has a carriage 15 which is mounted on two vertical guide rods 16 anchored in the end plates 10 of the swivel frame 6. The carriage 15 has two bearing beams 17, which are preferably equipped with ball bushings 18 at the bearing points. Two vertical webs 19 connect the two bearing beams 17 to one another and are connected to one another at their upper end by a support plate 20.
Als Antriebsmittel für das Transportgerät 2 dienen eine An¬ triebsmaschine in Form eines pneumatisch betriebenen Ar¬ beitszylinders 21 und zwei für den Lastausgleich vorge¬ sehene Gasfedern 22. Der Arbeitszylinder 21 und die Gas- federn 22 sind in der Ebene des Schwenkrahmens 6 angeord¬ net und stützen sich einerseits an der unteren Stirnplattte 10 des Schwenkrahmens 6 und andererseits an der oben .lie¬ genden Stützplatte 20 des Schlittens 15 ab. Beim Arbeits¬ zylinder 21 befindet sich der Zylinderteil unten und die Kolbenstange oben, bei- den Gasfedern 22 ist es umgekehrt.A drive machine in the form of a pneumatically operated working cylinder 21 and two gas springs 22 provided for load balancing serve as drive means for the transport device 2. The working cylinder 21 and the gas springs 22 are arranged in the plane of the swivel frame 6 and are supported on the one hand on the lower end plate 10 of the swivel frame 6 and on the other hand on the upper support plate 20 of the slide 15. In the case of the working cylinder 21, the cylinder part is at the bottom and the piston rod is at the top, with the gas springs 22 the reverse is the case.
Am Schlitten 15 des Transportgerätes 2 ist die Personen- tragvorrichtung 23 befestigt, und zwar ist im vorliegen¬ den Beispiel an zwei Holmen 24, die seitlich an den Lager- balken 17 des Schlittens 15 angebracht sind, ein Liege¬ sitz 25 um die Gelenke 26 hochklappbar montiert. Ferner können an den Holmen 24 hochklappbare Armlehnen vorgesehen sein.The person carrying device 23 is fastened to the carriage 15 of the transport device 2, and in the present example there is a reclining seat 25 around the joints 26 on two bars 24, which are attached laterally to the bearing beams 17 of the carriage 15 mounted foldable. Furthermore, 24 foldable armrests can be on the spars be provided.
Zum Betrieb des Arbeitszylinders 21 kann eine Druckfla¬ sche mit gespeichertem Gas, z.B. CO_, vorgesehen sein, wobei in diesem Fall vorzugsweise das Gestell 1 eine nicht besonders gezeichnete Halterung für diese Druck¬ flasche aufweist.To operate the working cylinder 21, a pressure bottle with stored gas, e.g. CO_, can be provided, in which case the frame 1 preferably has a holder (not shown) for this pressure bottle.
In Abänderung zu dem vorstehend beschriebenen Ausführungs- beispiel kann der Montagerahmen 5 auch Teil eines ortsfest oder fahrbaren Ständers bilden. In bezug auf den Antrieb des Transportgerätes 2 besteht ferner z.B. die Möglich¬ keit einen hydraulisch betriebenen Antriebszylinder oder einen elektromotorischen Spindel- oder Kettentrieb vor- zusehen. In a modification of the exemplary embodiment described above, the mounting frame 5 can also form part of a stationary or mobile stand. With regard to the drive of the transport device 2 there is also e.g. the possibility of providing a hydraulically operated drive cylinder or an electromotive spindle or chain drive.
