Abstract

The equipment comprises a seat plate (1) lifted and lowered by a drive mechanism, together with a backrest (6), while an actuator works between the mechanism and the plate. The actuator incorporates a support (9) engaging with the plate and extensible downwards from it. This acts against a baseplate, so as to lift the plate. There can be a scissor linkage (3) between the seat plate and baseplate. A rack consisting of toothed segments (8.1) stored in a shaft can engage with the top end of the support. A motor-driven pinion (12) meshes with the segments. It, the motor (11) and the shaft are accommodated in the backrest above the seat plate.

Description

Die Erfindung betrifft eine Vorrichtung zum Einsetzen in eine Badewanne oder dergleichen als Ein- und Ausstiegshilfe.The invention relates to a device for inserting into a bathtub or the like as an entry and exit aid.

Derartige Vorrichtungen sind für ältere oder gebrechliche Personen hilfreich oder unerläßlich. Sie ermöglichen ein sicheres und bequemes Ein- und Aussteigen in eine Badewanne, einen Zuber oder dergleichen.Such devices are helpful or essential for the elderly or frail. They enable safe and convenient entry and exit into a bathtub, tub or the like.

Die Grundkonstruktion hat in jedem Falle eine Sitzplatte. Die Sitzplatte ist im allgemeinen von einem Scherengestell getragen, dessen Scherenhebel verstellbar sind und damit ein Verändern der Höhe der Sitzplatte bewirken. Auch bezüglich des Antriebes gibt es mehrere Möglichkeiten. Der Antrieb kann elektromotorisch sein oder pneumatisch oder in der Ausnutzung des Wasserdruckes des kommunalen Wassernetzes bestehen.The basic construction always has a seat plate. The seat plate is generally carried by a scissor-type frame, the scissor levers of which are adjustable and thus cause a change in the height of the seat plate. There are also several options for the drive. The drive can be electromotive or pneumatic or consist of utilizing the water pressure of the municipal water network.

Die bisher bekanntgewordenen Vorrichtungen haben sich mehr oder minder gut bewährt. Schwachpunkte sind jedoch immer wieder Mangel der Sicherheit, zu großes Gewicht sowie geringer Bedienungskomfort.The devices which have become known to date have more or less proven their worth. Weak points are always lack of security, excessive weight and low ease of use.

Der Erfindung liegt die Aufgabe zugrunde, Sicherheit und Bedienungskomfort zu steigern, aber das Gewicht zu senken.The invention has for its object to increase safety and ease of use, but to reduce the weight.

Diese Aufgabe wird durch die kennzeichnenden Merkmale von Anspruch 1 gelöst.This object is solved by the characterizing features of claim 1.

Ein ganz entscheidender Vorteil, der sich aus der Erfindung ergibt, besteht darin, daß es hierbei möglich ist, den Motor an der Rücklehne anzubringen, ja sogar in deren oberem Bereich, so daß er vom Niveau des Wassers in der Badewanne möglichst weit weg ist.A very decisive advantage resulting from the invention is that it is possible to mount the motor on the backrest, even in the upper area, so that it is as far away from the level of water in the bath as possible.

Die Erfindung ist anhand der Zeichnung näher erläutert. Figur 1 zeigt eine Sitzvorrichtung in einer Seitenansicht. Man erkennt dort die Sitzplatte 1 sowie eine Bodenplatte 2. Diese beiden sind mittels eines Scherengestells 3 miteinander verbunden. Im vorderen Bereich auf der Oberseite der Sitzplatte befinden sich zwei Drucktasten, mit denen der Benutzer das Auffahren bzw. Abfahren steuern kann.The invention is explained in more detail with reference to the drawing. Figure 1 shows a seat device in a side view. The seat plate 1 and a base plate 2 can be seen there. These two are connected to one another by means of a scissor-type frame 3. In the front area on the top of the seat plate there are two pushbuttons with which the user can control the opening and closing.

Ein wesentliches Element ist eine Rückenlehneneinheit 5, die mehrere Einzelteile umfaßt. Die Einheit 5 weist eine Rückenlehne 6 auf, die ähnlich wie die Sitzplatte 1 aufgebaut sein kann. Auf der Rückseite der Rückenlehnenplatte befindet sich ein Mechanismus, der ganz wesentliche Elemente der Erfindung enthält, die man besonders gut aus den Figuren 2, 4 und 5 erkennt.An essential element is a backrest unit 5, which comprises several individual parts. The unit 5 has a backrest 6, which can be constructed similarly to the seat plate 1. On the back of the backrest plate there is a mechanism which contains very essential elements of the invention, which can be seen particularly well from FIGS. 2, 4 and 5.

Figur 2 ist eine Ansicht auf die Sitzvorrichtung in benutzungsfähigem Zustand von hinten. Wie man sieht, geht der Führungsschacht 6.1 in einen weiteren Schacht 6.2 über, wobei diese beiden Schächte gemeinsam wenigstens annähernd die Gestalt eines Spazierstockes haben. In Führungsschacht 6.1 befindet sich eine Zahnstange 8. Diese ist aus einer Vielzahl von Zahnstangensegmenten 8.1 aufgebaut. Die Zahnsegmente 8.1 sind gelenkig miteinander verbunden. Sie laufen einerseits im Führungsschacht 6.1, andererseits im Schacht 6.2, der im folgenden "Zahnstangenschacht" genannt wird.Figure 2 is a rear view of the seat assembly in a usable condition. As can be seen, the guide shaft 6.1 merges into a further shaft 6.2, whereby these two shafts together have at least approximately the shape of a walking stick. In the guide shaft 6.1 there is a rack 8. This is made up of a plurality of rack segments 8.1. The tooth segments 8.1 are connected to one another in an articulated manner. They run on the one hand in the guide shaft 6.1, and on the other hand in the shaft 6.2, which is referred to below as the "rack shaft".

Figur 5 ist eine vergrößerte Teilansicht des Gegenstandes von Figur 2. Diese Figur läßt Einzelheiten des Aufbaus der Zahnstange 8 erkennen. Wie man sieht, ist ein Ritzel 12 vorgesehen, dessen Zähne mit den Zähnen der Zahnstangensegmente 8.1 kämmen. Auf diese Weise ist die Zahnstange 8 in Führungsschacht 6.1 sowie in Zahnstangenschacht 6.2 gleitend verschiebbar und kann dabei der Kanalkrümmung im oberen Bereich der Einheit 5 folgen.Figure 5 is an enlarged partial view of the object of Figure 2. This figure reveals details of the structure of the rack 8. As can be seen, a pinion 12 is provided, the teeth of which mesh with the teeth of the rack segments 8.1. In this way, the rack 8 is slidably displaceable in the guide shaft 6.1 and in the rack shaft 6.2 and can follow the channel curvature in the upper region of the unit 5.

Wiederum insbesondere aus den Figuren 1 und 2 ersichtlich, erkennt man, daß am unteren Ende der Zahnstange 8 eine Stütze 9 angreift. Bei einer Verschiebung der Zahnstange 8 in den genannten Schächten 6.1 und 6.2 findet somit auch eine Bewegung der Stütze 9 statt, und zwar abwärts bzw. aufwärts.Again, particularly from Figures 1 and 2, it can be seen that a support 9 engages at the lower end of the rack 8. When the rack 8 is displaced in the shafts 6.1 and 6.2 mentioned, there is therefore also a movement of the support 9, namely downwards or upwards.

Die Figuren 3 und 4 zeigen die Sitzvorrichtung bei zusammengeklapptem Scherengestell 3. In diesem Zustand befinden sich Sitzplatte 1 und Bodenplatte 2 so nahe beieinander, wie dies die Konstruktion erlaubt. Dabei befindet sich die Zahnstange 8 nunmehr vollständig im Zahnstangenschacht 6.2, und die Stütze 9 befindet sich vollständig in Führungsschacht 6.1.FIGS. 3 and 4 show the seat device with the scissor frame 3 folded. In this state, the seat plate 1 and base plate 2 are as close to one another as the construction allows. The rack 8 is now completely in the rack shaft 6.2, and the support 9 is completely in the guide shaft 6.1.

Die Sitzvorrichtung arbeitet wie folgt:
Befindet sich die Sitzvorrichtung in dem Zustand, der in den Figuren 3 und 4 gezeigt ist, und wird Ritzel 12 von Getriebemotor 11 im Gegenzeigersinn angetrieben, so wird hierdurch die Zahnstange 8 in Bewegung versetzt, und zwar derart, daß ihr in Figur 4 rechtes Ende abwärts gedrückt wird. Wegen der Verbindung zwischen Zahnstange 8 und Stütze 9 wird Stütze 9 ebenfalls nach unten gedrückt. Dabei wird ein Druck gegen die Bodenplatte 2 ausgeübt, so daß die Rückenlehneneinheit 5 und damit auch die mit dieser fest verbundene Sitzplatte 1 angehoben wird. Dies geht so lange, bis der in den Figuren 1 und 2 dargestellte Zustand erreicht ist.The seat device works as follows:
If the seat device is in the state shown in FIGS. 3 and 4 and the pinion 12 is driven by the geared motor 11 in the counterclockwise direction, the rack 8 is set in motion in such a way that its right end in FIG. 4 is pressed down. Because of the connection between rack 8 and support 9, support 9 is also pressed down. A pressure is exerted against the base plate 2 so that the backrest unit 5 and thus also the seat plate 1 firmly connected to it is raised. This continues until the state shown in FIGS. 1 and 2 is reached.

Will man die Sitzplatte 1 absenken (und damit auch zwangsläufig die Rückenlehneneinheit 5), so wird Getriebemotor 11 im umgekehrten Drehsinn angetrieben, so daß Ritzel 12 im Zeigersinn umläuft. Zahnstange 8 wird somit mehr und mehr in den Zahnstangenschacht 6.1 eingeschoben, und Stütze 9 verschwindet mehr und mehr in Führungsschacht 6.1.If you want to lower the seat plate 1 (and thus necessarily the backrest unit 5), the geared motor 11 is driven in the opposite direction, so that the pinion 12 rotates clockwise. Rack 8 is thus pushed more and more into the rack shaft 6.1, and support 9 disappears more and more into the guide shaft 6.1.

Befindet sich die Sitzvorrichtung im Zustand gemäß der Figuren 3 und 4, so läßt sich die Rückenlehneneinheit 5 umklappen, so daß der in Figur 6 dargestellte Zustand erreicht wird. Damit ist die Sitzvorrichtung zu einem relativ kleinen und handlichen Paket zusammengeklappt. Bei entsprechend geringem Gewicht läßt sich die Vorrichtung leicht transportieren. Dies kann dann wichtig sein, wenn beispielsweise behinderte oder ältere Menschen auf Reisen gehen.If the seat device is in the state according to FIGS. 3 and 4, the backrest unit 5 can be folded down, so that the state shown in FIG. 6 is reached. So that the seat device is folded into a relatively small and handy package. With a correspondingly low weight, the device can be easily transported. This can be important if, for example, disabled or elderly people travel.

Gemäß der Erfindung ist auch für die notwendige Sicherheit beim Betrieb der Sitzvorrichtung Sorge getragen. Durch besondere bauliche Maßnahmen ist zunächst sichergestellt, daS die Stütze 9 beim Ein- und Ausfahren exakt und zuverlässig in der Position verbleibt, die sie beim Ein- oder Ausfahren haben soll. Es wird somit genau der Winkel eingehalten, unter dem sie sich bei den Zuständen gemäß der Figuren 1 und 2 sowie 3 und 4 in Bezug auf die Bodenplatte 2 befindet. Wie dies ausgeführt ist, ist in Figur 7 veranschaulicht. Vor dem Fuß der Stütze 9 befindet sich nämlich ein Rastwinkel 10. In diesem ist ein Schieber 10.1 gleitend geführt. Schieber 10.1 weist ein Langloch auf, durch welches ein in Rastwinkel 10 eingelassener Sicherungsstift 10.3 hindurchgreift. Schieber 10.1 weist eine Axialbohrung auf, die eine Zugfeder 10.2 enthält. Schieber 10.1 weist an seinem vorderen Ende ein Winkelstück auf. Dieses arbeitet mit einem Keil 1.1 zusammen, der an Sitzplatte 1 befestigt ist. Die beiden Teile, nämlich Winkelstück und Keil 1.1 haben Anschlagflächen, die im dargestellten Zustand gemäß Figur 7 aneinander anliegen. Wie man ferner sieht, liegt dem hinteren Ende des Schiebers 10.1 eine Bohrung im Fuß der Stütze 9 gegenüber. In diesem hier dargestellten Zustand greift Schieber 10.1 nicht in diese Bohrung ein.According to the invention, the necessary safety when operating the seat device is also taken care of. Special structural measures initially ensure that the support 9 remains exactly and reliably in the position it is supposed to have when entering or exiting when extending and retracting. The angle at which it is in relation to the base plate 2 in the states according to FIGS. 1 and 2 and 3 and 4 is thus observed. How this is carried out is illustrated in FIG. 7. In front of the foot of the support 9 there is a latching angle 10. A slide 10.1 is slidably guided in this. Slider 10.1 has an elongated hole through which a locking pin 10.3 inserted into the detent bracket 10 extends. Slider 10.1 has an axial bore which contains a tension spring 10.2. Slider 10.1 has an elbow at its front end. This works together with a wedge 1.1, which is attached to the seat plate 1. The two parts, namely the angle piece and the wedge 1.1, have abutment surfaces which bear against one another in the state shown in FIG. 7. As can also be seen, there is a hole in the foot of the support 9 opposite the rear end of the slide 10.1. In the state shown here, slide 10.1 does not engage in this bore.

Wird die Sitzvorrichtung ausgefahren, so daß sich Sitzplatte 1 nach oben bewegt und damit von Bodenplatte 2 entfernt, so entfernt sich auch Keil 1.1 vom Winkelstück des Schiebers 10.1. Die beiden genannten Anschlagflächen gelangen somit außer Eingriff. In diesem Augenblick kann die Zugefeder 10.2 wirken. Sie ist mit ihrem hinteren Ende am Anschlagstift 10 befestigt und mit ihrem vorderen Ende an Schieber 10.1. Sie bewirkt, daß Schieber 10.1 mit seinem hinteren Ende in die Bohrung im Fuß der Stütze 9 einrastet. Damit ist Stütze 9 gegen ein Verrutschen oder Verschieben gesichert. Diese Sicherung hält an während des gesamten Verstellvorganges und selbstverständlich auch in ausgefahrenem Zustand der Sitzplatte 1.If the seat device is extended so that the seat plate 1 moves upwards and thus from the base plate 2 removed, wedge 1.1 also moves away from the contra-angle of the slide 10.1. The two abutment surfaces mentioned thus come out of engagement. The spring 10.2 can act at this moment. It is attached with its rear end to the stop pin 10 and with its front end to slide 10.1. It causes slide 10.1 to engage with its rear end in the bore in the foot of support 9. So that support 9 is secured against slipping or moving. This fuse lasts during the entire adjustment process and of course also when the seat plate 1 is extended.

Es ist eine weitere Sicherungsmaßnahme getroffen, die dafür sorgt, daß die Rückenlehneneinheit 5 in aufgerichtetem Zustand stets in ein und derselben Position verbleibt. Diese Sicherungsmaßnahme ist in Figur 8 veranschaulicht. Diese Figur zeigt die Sitzvorrichtung in einer Seitenansicht ähnlich der Darstellung gemäß Figur 1, jedoch stark vergrößert und ohne die Zahnstange 8 mit Stütze 9. Man erkennt im einzelnen wieder die Sitzplatte 1, die Gelenklasche 7, an welcher die Rückenlehneneinheit 5 mittels Gelenkachse 7.1 angelenkt ist, den Führungsschacht 6.1 zur Aufnahme der hier nicht gezeigten Stütze, und schließlich die Bodenplatte 2.A further safety measure has been taken, which ensures that the backrest unit 5 always remains in the same position in the erected state. This security measure is illustrated in FIG. 8. This figure shows the seat device in a side view similar to the illustration according to FIG. 1, but greatly enlarged and without the rack 8 with support 9. One can again see in detail the seat plate 1, the articulated bracket 7, to which the backrest unit 5 is articulated by means of the articulated axis 7.1 , the guide shaft 6.1 for receiving the support, not shown here, and finally the base plate 2.

Die entscheidenden Bauteile sind ein Kipphebel 30, der um eine Gelenkachse 30.1, welche am Führungsschacht 6.1 angeordnet ist, kippbar ist, ferner eine Sperrklinke 31, die um eine Gelenkachse 31.3 schwenkbar ist. Sie ist dort von einem Lagerbock 32 gelagert. Weitere wichtige Bauteile sind eine Zugfeder 33, eine Druckfeder 34 sowie ein Auslösestift 35.The decisive components are a rocker arm 30, which can be tilted about an articulation axis 30.1, which is arranged on the guide shaft 6.1, and also a pawl 31, which can be pivoted about an articulation axis 31.3. It is supported there by a bearing block 32. Other important components are a tension spring 33, a compression spring 34 and a release pin 35.

Wie man sieht, arbeiten Kipphebel 30 und Sperrklinke 31 derart zusammen, daß sie ineinander einrasten können. Man beachte die Keilspitze 31.4 von Sperrklinke 31 sowie die entsprechende Aussparung 30.2 von Kipphebel 30. Greifen diese beiden Teile ineinander, so ist die Rückenlehneneinheit 5 gegen Umkippen nach vorn gesichert. Sind die beiden Teile hingegen voneinander gelöst, so kann die Rückenlehneneinheit 5 nach vorn umgeklappt werden, so daß der in Figur 6 dargestellte Zustand erreicht wird. Das Letztere ist dann erwünscht, wenn Sitzplatte 1 und Bodenplatte 2 einander angenähert werden. Dieses Auslösen erfolgt zwangsläufig bei einem gegenseitigen Annähern von Sitzplatte 1 und Bodenplatte 2, und zwar dadurch, daß der vordere Teil der Sperrklinke 34 am Auslösestift 35 anschlägt.As can be seen, rocker arm 30 and pawl 31 work together in such a way that they can snap together. Note the wedge tip 31.4 of pawl 31 and the corresponding recess 30.2 of rocker arm 30 these two parts into one another, so the backrest unit 5 is secured against tipping forward. However, if the two parts are detached from each other, the backrest unit 5 can be folded forward so that the state shown in FIG. 6 is reached. The latter is desirable when the seat plate 1 and base plate 2 are brought closer together. This release takes place inevitably when the seat plate 1 and the base plate 2 approach each other, specifically in that the front part of the pawl 34 strikes the release pin 35.

Es versteht sich, daß die Rückenlehnensicherung gemäß Figur 8 auch unabhängig von dem Hauptgedanken der Erfindung mit Zahnstange und Stütze anwendbar ist.It goes without saying that the backrest safety device according to FIG. 8 can also be used independently of the main idea of the invention with a toothed rack and support.

Die Figuren 9, 10 und 11 zeigen eine weitere Ausführungsform der Erfindung. Der Grundgedanke ist hierin beibehalten. Es ist nämlich wiederum eine Stütze 9 vorgesehen, die eine Änderung des Abstandes zwischen Sitzplatte 1 und Bodenplatte 2 bewirkt, und somit das Auseinanderfahren bzw. Zusammenfahren des Scherengestelles 3. Auch hier ist wiederum ein Getriebemotor 11 vorgesehen, der auf einer Motorkonsole 22 sitzt und der ein Ritzel 12 antreibt. Läuft das Ritzel 12 in Figur 9 im Gegenzeigersinn um, so wandert es gewissermaßen an der Stütze 9 nach unten entlang und nimmt damit die Sitzplatte 1 mit der Rückenlehne 6 mit, wobei das Scherengestell 3 zusammengefaltet wird.Figures 9, 10 and 11 show a further embodiment of the invention. The basic idea is retained here. This is because a support 9 is again provided, which causes a change in the distance between the seat plate 1 and the base plate 2, and thus the moving apart or moving together of the scissors-type frame 3. Here too, a geared motor 11 is again provided, which sits on a motor console 22 and which a pinion 12 drives. If the pinion 12 rotates in the counterclockwise direction in FIG. 9, it migrates downward along the support 9 and thus takes the seat plate 1 with the backrest 6 along, the scissor-type frame 3 being folded up.

Im Unterschied zur Ausführungsform gemäß der Figuren 1 bis 8 fehlen hier die gelenkige Zahnstange mit dem Zahnstangenschacht. Die Stütze 9 ist selbst als Zahnstange ausgebildet. Ein Führungsschacht fehlt ebenfalls.In contrast to the embodiment according to FIGS. 1 to 8, the articulated rack with the rack shaft is missing here. The support 9 is itself designed as a rack. A guide shaft is also missing.

Wichtig ist, daß auch bei dieser Ausführungsform gemäß der Figuren 9, 10 und 11 die Vorzüge der Erfindung voll und ganz erhalten bleiben. Diese bestehen in einer extrem einfachen und damit leichten Konstruktion, einer vollständigen Zusammenklappbarkeit zu einem kleinen Paket sowie in der Sicherheit und dem Komfort der Bedienung.It is important that in this embodiment according to Figures 9, 10 and 11, the advantages of the invention fully and remain intact. These consist of an extremely simple and therefore lightweight construction, a complete collapsibility into a small package and the safety and comfort of operation.

Die Figuren 12, 13 und 14 zeigen eine weitere Ausführungsform der Erfindung. Auch hier ist wiederum eine Stütze 9 vorgesehen. Diese ist jedoch als Gewindespindel ausgebildet. Sie ist durch eine Mutter hindurchgeführt (im einzelnen nicht dargestellt). Die Mutter ist ihrerseits an der Sitzplatte 1 ortsfest fixiert, jedoch durch den Getriebemotor 11 antreibbar, so daß sie entlang der Stütze 9 auf- und abwandert, und damit auch die Sitzplatte 1 samt Lehne 6 mitnimmt. Figur 12 zeigt den ausgefahrenen Zustand mit der Sitzplatte 1 in der maximalen Höhe, Figur 3 den eingefahrenen Zustand, bei dem sich Sitzplatte 1 und Bodenplatte 2 so nahe wie möglich beieinander befinden, und Figur 14 zeigt den zusammengeklappten Zustand, bereit zum Transport.Figures 12, 13 and 14 show a further embodiment of the invention. Here again, a support 9 is provided. However, this is designed as a threaded spindle. It is passed through a nut (not shown in detail). The mother is in turn fixed in place on the seat plate 1, but can be driven by the geared motor 11, so that it moves up and down along the support 9, and thus also takes the seat plate 1 together with the backrest 6. FIG. 12 shows the extended state with the seat plate 1 at the maximum height, FIG. 3 shows the retracted state in which the seat plate 1 and base plate 2 are as close as possible to one another, and FIG. 14 shows the folded state, ready for transport.
