Abstract

A bathtub insert for handicapped persons comprises a bottom frame, a seat plate, two pairs of scissor arms therebetween and a hose fillable with water in order to elevate the seat plate. A flexible cover sheet closes the front end of the bathtub insert between the seat plate and the bottom frame. One end of the cover sheet is fastened at a winding tube and a torsional spring therein holds the cover sheet tightly tensioned even in the lowermost position of the seat plate. The cover sheet at the same time avoids that handicapped persons can be injured by jamming their arms and legs and holds the bathtub insert in a flat-package transportable position.

Description

Die Erfindung betrifft einen Badewanneneinsatz bestehend aus einem Bodengestell, einer Sitzplatte, einer aus zwei Scherenarmpaaren bestehenden Führungseinrichtung zwischen Bodengestell und Sitzplatte, sowie einem mit Wasser füllbaren Schlauch als Hubeinrichtung, dessen geschlossene Enden je am Bodengestell und an der Sitzplatte befestigt sind, wobei die Sitzplatte zwei seitliche, in die Ebene der Sitzplatte vorgespannte Schwenkplatten aufweist.The invention relates to a bathtub insert consisting of a base frame, a seat plate, a guide device consisting of two pairs of scissor arms between the base frame and the seat plate, and a hose that can be filled with water as a lifting device, the closed ends of which are attached to the base frame and the seat plate, the seat plate being two has lateral pivot plates biased into the plane of the seat plate.

Ein Badewanneneinsatz dieser Art ist aus der EP-PS 74 460 bekannt. Die Sitzplatte erstreckt sich über die ganze Länge der Badewanne und weist ebenfalls stirnseitige Schwenkplatten auf, sodaß beim Absenken der Sitzplatte keine Spalten zwischen dieser und der Badewanne entstehen können, in denen sich Behinderte einklemmen könnten. Solche langen Badewanneneinsätze haben aus Stabilitätsgründen eine doppelte Führungseinrichtung, also zwei vordere und zwei hintere Scherenarmpaare. Wenn der Behinderte auf das Liegen in der Wanne verzichten kann, so genügt ein einfacherer Badewanneneinsatz, der eine kürzere Sitzplatte hat, die sich nur über etwa die halbe Wannenlänge erstreckt. Solche Badewanneneinsätze sind beispielsweise aus der US-PSen2 725578 und. 2 772 721 bekannt. Bei beiden bekannten Badewanneneinsätzen besteht das Problem, daß der Behinderte beim Absenken der Sitzplatte sich an dieser festzuhalten sucht und sich dabei durch Einklemmen verletzen kann. Beim Gegenstand der US-PS 27 25 578 kann dies zwischen den den Hubbalg aussteifenden Innenringen bzw. dem obersten Innenring und der Sitzplatte geschehen, während beim Badewanneneinsatz gemäß US-PS 27 72 721 Verklemmungsgefahr zwischen den Scherenarmen und der Sitzplatte und dem Bodengestell besteht. Behinderte haben erfahrungsgemäß häufig nicht volle Kontrolle über die Bewegungen ihrer Glieder und so ist es nicht nur möglich, sondern auch schon vorgekommen, daß bei bekannten Geräten Behinderte ihre Beinunterschenkel unter die Sitzplatte schwenken. Beim Abwärtsfahren der Sitzplatte sind dann erhebliche Verletzungen nicht vermeidbar.A bathtub insert of this type is known from EP-PS 74 460. The seat plate extends over the entire length of the bathtub and also has end-side swivel plates, so that when the seat plate is lowered, no gaps can arise between it and the bathtub, in which the disabled could get caught. For reasons of stability, such long bathtub inserts have a double guide device, ie two front and two rear scissor arm pairs. If the disabled person can do without lying in the tub, a simpler use of the bathtub with a shorter seat plate, which only extends over about half the tub length, is sufficient. Such bathtub inserts are, for example, from US Pat. No. 2,725,578 and. 2,772,721 is known. In both known bathtub inserts there is the problem that the disabled hold on to the seat panel when lowering it seeks and can injure itself by being pinched. In the subject of US-PS 27 25 578 this can happen between the inner bellows stiffening the bellows or the uppermost inner ring and the seat plate, while there is a risk of jamming between the scissor arms and the seat plate and the base frame when using the bathtub according to US-PS 27 72 721. Experience has shown that disabled people often do not have full control over the movements of their limbs and so it is not only possible, but has also happened that, in known devices, disabled people swivel their lower legs under the seat plate. When the seat plate is moved downwards, considerable injuries cannot be avoided.

Aufgabe der Erfindung ist es, den Badewanneneinsatz der eingangs genannten Art so auszubilden, daß Verletzungen beim Gebrauch des Badewanneneinsatzes durch Behinderte mit Sicherheit vermieden werden.The object of the invention is to design the bathtub insert of the type mentioned at the outset in such a way that injuries to the use of the bathtub insert by the disabled are avoided with certainty.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß an der Vorderseite des Badewanneneinsatzes zwischen Sitzplatte und Bodengestell eine rolloartige, flexible Abdeckung vorgesehen ist, deren Breite nahezu gleich derjenigen des Bodengestells ist und deren eines Ende an der Sitzplatte oder dem Bodengestell befestigt und deren anderes Ende auf einem, am Bodengestell bzw. an der Sitzplatte drehbar gelagerten Wickelrohr befestigt ist, in das eine Torsionsfeder mit einer, die Abdeckung auch in der Tiefstellung der Sitzplatte in straffem Zustand haltenden Vorspannung eingesetzt ist.This object is achieved in that a roller blind-like, flexible cover is provided on the front of the bath insert between the seat plate and base frame, the width of which is almost equal to that of the base frame and one end of which is on the seat plate or the base frame strengthens and the other end of which is fastened to a winding tube which is rotatably mounted on the base frame or on the seat plate, into which a torsion spring with a pretensioning which holds the cover even in the lowered position of the seat plate is inserted.

Mit der Erfindung wird der Vorteil erreicht, daß sämtliche beweglichen Teile zwischen Sitzplatte und Bodengestell abgedeckt sind, sodaß der Behinderte weder mit den Füßen noch mit den Händen der Verklemmungsgefahr ausgesetzt ist. Die Abdeckung hat naturgemäß in der Hochstellung der Sitzplatte die stärkste Spannung und diese ist so stark, daß der Behinderte nicht einmal mutwillig die Abdeckung aus der geraden Strecklage einbuchten kann. Aber auch in der Tiefstellung und kurz bevor Erreichen der Tiefstellung hat die Abdeckung eine ausreichende Spannkraft, sodaß auch hier ein wirksamer Schutz besteht. Ein weiterer Vorteil der Erfindung besteht darin, daß die Vorspannung der Abdeckung ausreicht, daß die Sitzplatte von selbst an das Bodengestell herangezogen wird, sodaß die Ruhestellung des Badewanneneinsatzes gleichzeitig die Transportstellung ist, sodaß zusätzliche Verriegelungseinrichtungen entfallen. Die beiden seitlichen Schwenkplatten der Sitzplatte legen sich an die Badewanne selbsttätig an und verhindern hier eine Spaltenbildung. Seitlich ist der Behinderte also auch vor einem Einklemmen geschützt.The advantage of the invention is that all moving parts between the seat plate and the base frame are covered, so that the disabled person is not exposed to the risk of jamming, either with the feet or with the hands. The cover naturally has the greatest tension when the seat plate is in the high position and this is so strong that the handicapped cannot even want to book the cover from the straight stretched position. But even in the low position and shortly before reaching the low position, the cover has a sufficient clamping force, so that there is also effective protection here. Another advantage of the invention is that the pretensioning of the cover is sufficient for the seat plate to be pulled onto the base frame by itself, so that the rest position of the bathtub insert is at the same time the transport position, so that additional locking devices are not required. The two side swivel plates on the seat plate automatically attach themselves to the bathtub and prevent them a column formation here. So the handicapped person is also protected from being pinched.

Eine Weiterbildung besteht noch darin, daß die Abdeckung in der Hochstellung der Sitzplatte sich unter einem Winkel im Bereich von 10° bis etwa 20° nach oben und hinten erstreckt. Die Zugwirkung der Abdeckung erfolgt also mit einer auf die Sitzplatte ausgeübten Vorwärtskomponente. Dies ist insbesondere vorteilhaft in-Verbindung mit einer in bestimmter Form ausgebildeten Führungseinrichtung, die erfindungsgemäß dafür sorgt, daß beim Heben der Sitzplatte sich diese gleichzeitig mit einer Komponente nach hinten bewegt. Dies wird erfindungsgemäß dadurch erreicht, daß die Enden der vier Arme beider Scherenarmpaare jeweils ein festes Schwenklager und ein Schwenklager in einem, in einer Schiene verschiebbaren Schiebestück aufweisen, daß die vier festen Schwenklager im Hinterbereich des Badewanneneinsatzes angeordnet sind und daß die zwischen der gemeinsamen Mittelgelenkachse aller vier Arme und den beiden Schwenklagern an den vorderen bodenseitigen Schiebestücken jeweils gemessene Hebellänge größer als die drei anderen jeweils zwischen der Mittelgelenkachse und den Schwenklagern gemessenen Hebellängen ist. Mit dieser Maßnahme bewegt sich die Sitzplatte angenähert parallel zur schrägen Wannenendfläche. Der zwischen Sitzplatte und Wannenendfläche gebildete Spalt kann sich also nicht so verkleinern, daß hier eine Verletzungsgefahr durch Einklemmen besteht. Gleichzeitig hat diese Art der Bewegung der Sitzplatte den Vorteil, daß diese beim Heben allmählich eine leichte Neigungslage nach hinten einnimmt, was den großen Vorteil hat, daß der Behinderte auf der Sitzplatte nicht nach vorn rutschen kann.A further development is that the cover extends upwards and backwards at an angle in the range from 10 ° to approximately 20 ° in the high position of the seat plate. The pulling action of the cover thus takes place with a forward component exerted on the seat plate. This is particularly advantageous in connection with a guide device designed in a certain shape, which according to the invention ensures that when the seat plate is lifted, it moves backwards simultaneously with a component. This is achieved according to the invention in that the ends of the four arms of both pairs of scissor arms each have a fixed pivot bearing and a pivot bearing in a sliding piece which can be displaced in a rail, that the four fixed pivot bearings are arranged in the rear region of the bathtub insert and that between the common central joint axis of all four arms and the two pivot bearings on the front bottom sliding pieces each measured lever length is greater than the three other lever lengths measured between the central joint axis and the pivot bearings. With this measure, the seat plate moves approximately parallel to the sloping end surface of the tub. The one between the seat plate and the tub end Area formed gap can not be reduced so that there is a risk of injury by pinching. At the same time, this type of movement of the seat plate has the advantage that it gradually assumes a slight inclination towards the rear when lifting, which has the great advantage that the disabled cannot slide forward on the seat plate.

Um die Wasserfüllung in der Badewanne möglichst gut ausnützen zu können, muß eine möglichst niedrige Tiefstellung der Sitzplatte erreicht werden. Dabei darf aber die Stabilität der Führungseinricht nicht verringert werden. Zu diesem Zweck besteht ein weiteres Erfindungsmerkmal darin, daß die zwischen der gemeinsamen Mittelgelenkachse und den beiden Schwenklagern an den vorderen tischplattenseitigen Schiebestücken jeweils gemessene Hebellänge kleiner als die anderen drei Hebellängen ist. Diese Maßnahme würde für sich allein genommen zu einer Neigung der Sitzplatte nach vorne führen, was unerwünscht ist. In Verbindung mit der maßgeblichen Vergrößerung der an den bodenseitigen Schiebestücken angreifenden Armhebeln, wird jedoch eine solche Nachvorneneigung nicht nur kompensiert sondern,in eine Abwärtsneigung nach hinten verwandelt, wenn die Sitzplatte sich in der Hochstellung befindet. Die beiden hinteren, an den Festlagern angreifenden Armhebel sind vorzugsweise gleich lang. Bezüglich dieser Armhebellängen ist die vordere untere Armhebellänge im Bereich von etwa 10% bis etwa 20% größer, während die kürzere obere vordere Armhebellänge etwa 7% bis etwa 15% kürzer ist. Dadurch ergibt sich, daß die beiden Arme jedes Scherenarmpaars unterschiedlich lang sind und zwar ist der zum hinteren oberen Festschwenklager der Sitzplatte führende Arm im Bereich von etwa 10% bis etwa 15% länger als der andere Arm. Vorzugsweise hat dieses Armlängenverhältnis den Wert von 1,12.In order to be able to use the water filling in the bathtub as well as possible, the lowest possible position of the seat plate must be reached. However, the stability of the management facility must not be reduced. For this purpose, a further feature of the invention is that the lever length measured between the common central joint axis and the two pivot bearings on the front table-top sliding pieces is smaller than the other three lever lengths. This measure alone would lead to an inclination of the seat plate to the front, which is undesirable. In connection with the significant enlargement of the arm levers engaging on the sliding pieces on the bottom, such a forward inclination is not only compensated for, but is converted into a downward inclination towards the rear when the seat plate is in the high position. The two rear arm levers engaging on the fixed bearings are preferably of the same length. Regarding these arm lever lengths is the Front lower arm length is in the range of about 10% to about 20% longer, while the shorter upper front arm length is about 7% to about 15% shorter. This means that the two arms of each pair of scissor arms are of different lengths, namely that the arm leading to the rear upper fixed pivot bearing of the seat plate is in the range from about 10% to about 15% longer than the other arm. This arm length ratio is preferably 1.12.

Mit der vorstehenden Armlängenausbildung wird einmal erreicht, daß die vier Festschwenklager in der Tiefstellung der Sitzplatte wenigstens angenähert koaxial liegen. Alle vier Arme liegen weiterhin in der Tiefstellung der Schwenkplatte auf dem selben Niveau. Daraus resultiert eine möglichst niedrige Tiefstellung der Schwenkplatte.With the above arm length training it is once achieved that the four fixed pivot bearings are at least approximately coaxial in the lowered position of the seat plate. All four arms are still at the same level when the swivel plate is lowered. This results in the lowest possible lowering of the swivel plate.

Um die Stabilität der Führungseinrichtung zu erhöhen sind je zwei gleichsinnig bewegte Arme der beiden Scherenarmpaare im Nachbarbereich ihrer verschiebbaren Schwenklager durch eine Querstrebe zu einem starren Schwenkrahmen verbunden. Somit ergeben sich zwei starre Schwenkrahmen. Gleichwohl können dank der unterschiedlichen vorderen Armlängen die Schwenkrahmen ineinander fahren, denn die Enden der die Schiebestücke tragenden Arme des inneren Schwenkrahmens liegen in der Tiefstellung der Sitzplatte unmittelbar benachbart hinter der Querstrebe des äußeren Rahmens.In order to increase the stability of the guide device, two arms of the two pairs of scissor arms, moved in the same direction, are connected in the adjacent region of their displaceable pivot bearings by a cross strut to form a rigid pivot frame. This results in two rigid swivel frames. Nevertheless, thanks to the different front arm lengths, the swivel frames can move into each other, because the ends of the rails Load-bearing arms of the inner swivel frame are in the lower position of the seat plate immediately adjacent to the cross strut of the outer frame.

Ein weiterer besonderer Vorteil der straffgespannten Abdeckung ist darin zu sehen, daß die Sitzplatte nach Gebrauch des Badewanneneinsatzes von selbst und ohne zusätzliche Belastung in die abgesenkte Ruhestellung gelangt, wobei das Wasser im Hubschlauch ausgepreßt wird, nachdem der Benutzer das Ventil umgeschaltet hat. Für das Personal in Krankenhäusern usw. bedeutet dies eine maßgebliche Arbeitserleichterung.Another particular advantage of the taut cover can be seen in the fact that the seat plate, after use of the bathtub insert, goes into the lowered rest position by itself and without additional load, the water in the lifting hose being squeezed out after the user has switched the valve. For the staff in hospitals etc. this means a significant reduction in work.

Anhand der Zeichnung, die ein Ausführungsbeispiel darstellt, sei die Erfindung näher beschrieben.The invention will be described in more detail with reference to the drawing, which represents an exemplary embodiment.

Der allgemein mit 10 bezeichnete Badewanneneinsatz besteht aus einem Bodengestell 12, einer Sitzplatte 14, zwei Scherenarmpaaren 16 sowie einer Hubeinrichtung in Form eines Schlauches 18, dessen geschlossene Enden am Bodengestell 12 und an der Sitzplatte befestigt sind. Die Sitzplatte 14 hat zwei seitliche, in die Ebene der Sitzplatte vorgespannte Schwenkplatten 20, die über die ganze Länge der Sitzplatte 14 reichen. Im Abstand vom Hinterende der Sitzplatte 14 ist in dieser eine Rückenlehne 22 lösbar eingesteckt.The bathtub insert, generally designated 10, consists of a base frame 12, a seat plate 14, two pairs of scissor arms 16 and a lifting device in the form of a hose 18, the closed ends of which are fastened to the base frame 12 and to the seat plate. The seat plate 14 has two lateral pivot plates 20 which are prestressed in the plane of the seat plate and extend over the entire length of the seat plate 14. At a distance from the rear end of the seat plate 14, a backrest 22 is detachably inserted therein.

Das Vorderende des Badewanneneinsatzes 10 ist zwischen Bodengestell 12 und Sitzplatte 14 durch eine flexible rolloartige Abdeckung 24 geschlossen. Die Abdeckung 24 hat nahezu dieselbe Breite wie das Bodengestell 12. Das obere Ende der Abdeckung 24 ist mittels einer Leiste 26 an der Unterseite der Sitzplatte 14 befestigt, während das untere Ende der Abdeckung 24 auf einem Wickelrohr 28 aufgewickelt ist, in das eine etwa koaxiale Torsionsfeder 30 eingesetzt ist. Das eine Ende des Wickelrohres 28 ist durch einen Stopfen 32 geschlossen, der einen koaxialen nach außen vorstehenden Achsstummel 34 aufweist, der in einem Lagerbock 36 an der Außenseite des Bodengestells 12 drehbar gelagert ist. In das andere Ende des Wickelrohres 28 ist ein Endstück 37 undrehbar eingesetzt, in welchem eine koaxiale Hohlachse 38 drehbar gelagert ist, deren gegenüberliegendes Ende in einem in das Wickelrohr 28 eingesetzten Scheibenring 40 geführt ist. Durch eine Bohrung im Endstück 37 ragt ein koaxialer Fortsatz 42 der Hohlachse 38 in diese hinein und ist mit der.Hohlachse 38 drehfest verklemmt. Dieser. koaxialer Fortsatz 42 ist im linksseitigen Lagerbock 44 undrehbar gehaltert und mittels eines Radialstiftes 46 gegen Drehung gesichert. Die Torsionsfeder 30 ist auf einem in das Wickelrohr 28 eingreifenden Gewindeabschnitt des Endstückes 37 aufgeschraubt. Das gegenüberliegende Ende der Torsionsfeder 30 ist auf einen Innendurchmesser reduziert, der dem Außendurchmesser der Hohlachse 28 entspricht. Dreht man vor der Montage des Wickelrohres 28 die Hohlachse 38 bei festgehaltenem Wickelrohr 28, so verklemmt sich das im Durchmesser reduzierte Ende der Torsionsfeder 30 auf der Hohlachse 38.und die Torsionsfeder 30 läßt sich in einen starken Spannungszustand versetzen. In diesem Zustand wird das Wickelrohr 28 dann in der beschriebenen Weise am Bodengestell 12 montiert und das andere Ende der Abdeckung 24 wird an der Sitzplatte 14 befestigt.The front end of the bath insert 10 is closed between the floor frame 12 and the seat plate 14 by a flexible roller blind-like cover 24. The cover 24 has almost the same width as the base frame 12. The upper end of the cover 24 is fastened to the underside of the seat plate 14 by means of a strip 26, while the lower end of the cover 24 is wound on a winding tube 28 into which an approximately coaxial Torsion spring 30 is used. One end of the winding tube 28 is closed by a plug 32, which has a coaxial stub shaft 34 projecting outwards, which is in a bearing block 36 the outside of the base frame 12 is rotatably mounted. In the other end of the winding tube 28, an end piece 37 is rotatably inserted, in which a coaxial hollow shaft 38 is rotatably mounted, the opposite end of which is guided in a disk ring 40 inserted into the winding tube 28. A coaxial extension 42 of the hollow axis 38 projects through a bore in the end piece 37 and is clamped in a rotationally fixed manner with the hollow axis 38. This. coaxial extension 42 is non-rotatably supported in the left-hand bearing block 44 and secured against rotation by means of a radial pin 46. The torsion spring 30 is screwed onto a threaded section of the end piece 37 which engages in the winding tube 28. The opposite end of the torsion spring 30 is reduced to an inner diameter which corresponds to the outer diameter of the hollow axis 28. If, before the winding tube 28 is assembled, the hollow axis 38 is rotated while the winding tube 28 is held tight, the end of the torsion spring 30 with reduced diameter is jammed on the hollow axis 38. And the torsion spring 30 can be put into a strong state of tension. In this state, the winding tube 28 is then mounted in the manner described on the base frame 12 and the other end of the cover 24 is on the Seat plate 14 attached.

Jedes Scherenarmpaar 16 besteht aus zwei unterschiedlich langen Armen 48, 50. Alle vier Arme 48, 48, 50, 50 sind durch eine gemeinsame mittlere Gelenkachse 52 schwenkbar miteinander verbunden. Der Arm 48 hat ein im Hinterbereich der Sitzplatte 14 fest angebrachtes Schwenklager 54 und ein unteres, an einem Schiebestück 56 vorgesehenes Schwenklager 58. Das Schiebestück 56 ist in einer Schiene 60 verschiebbar geführt, wobei die Mittelachse des Armes 48 mit der Mittelachse der Schiene 60 in derselben vertikalen Längsebene liegt. Obwohl die Schiene 60 sich nur von vorn bis etwa in den Mittelbereich des Bodengestells 12 zu erstrecken brauchte, reicht sie im Ausführungsbeispiel über nahezu die gesamte Länge des hier als Platte dargestellten Bodengestells, wodurch an Stabilität gewonnen wird.Each pair of scissor arms 16 consists of two arms 48, 50 of different lengths. All four arms 48, 48, 50, 50 are pivotally connected to one another by a common central joint axis 52. The arm 48 has a swivel bearing 54 fixedly attached in the rear region of the seat plate 14 and a lower swivel bearing 58 provided on a sliding piece 56. The sliding piece 56 is guided displaceably in a rail 60, the central axis of the arm 48 being aligned with the central axis of the rail 60 in is the same vertical longitudinal plane. Although the rail 60 only had to extend from the front to approximately in the central region of the base frame 12, in the exemplary embodiment it extends over almost the entire length of the base frame shown here as a plate, which increases stability.

In ähnlicher Weise sind die beiden Arme 50 jeweils innenseitig neben den Schienen 60 an hinteren festen Bodenschwenklagern 62 des Bodengestells 12 gelagert, während ihre oberen Enden in Schwenklagern 64 von Schiebestücken 66 gelagert sind, die ihrerseits in Schienen 68 längsverschiebbar geführt sind, welche an der Unterseite der Sitzplatte 14 befestigt sind. Auch hier würde es ansich genügen, die Schienen 68 nur in der vorderen Hälfte der Sitzplatte 14 anzuordnen. Die Verlängerung nach hinten bewirkt aber eine höhere Stabilität.Similarly, the two arms 50 are each mounted on the inside next to the rails 60 on rear fixed floor pivot bearings 62 of the floor frame 12, while their upper ends are mounted in pivot bearings 64 by sliding pieces 66, which in turn are guided in rails 68 which are longitudinally displaceable, which on the underside the seat plate 14 are attached. Here, too, it would in itself suffice to only engage the rails 68 in the front half of the seat plate 14 organize. The extension to the rear results in greater stability.

Nahe den bodenseitigen Schiebelagern 56 sind die Arme 48 durch eine hohle Querstrebe 70 miteinander zu einem starren Schwenkrahmen 72 verbunden. Die Montage erfolgt sehr einfach unter Verwendung eines in die beiden Arme 48 hineinreichenden Zugankers 74, auf den endseitig Muttern 76 aufgeschraubt sind. Der von den beiden äußeren Armen 48 und der Querstrebe 70 gebildete äußere Schwenkrahmen 72 hat also eine U-Form. Die beiden inneren Arme 50 sind ebenfalls benachbart der oberen Schiebestücke 66 durch eine Querstrebe 76 miteinander verbunden. Zusätzlich ist auch nahe den festen Schwenklagern 62 eine entsprechende Querstrebe 78 vorgesehen, sodaß ein innerer, ringsum geschlossener Schwenkrahmen 80 gebildet wird.Near the bottom sliding bearings 56, the arms 48 are connected to one another by a hollow cross strut 70 to form a rigid swivel frame 72. Installation is very simple, using a tie rod 74 which extends into the two arms 48 and on which nuts 76 are screwed on the end. The outer pivot frame 72 formed by the two outer arms 48 and the cross strut 70 thus has a U-shape. The two inner arms 50 are also connected to one another adjacent to the upper sliding pieces 66 by a cross strut 76. In addition, a corresponding cross strut 78 is also provided near the fixed pivot bearings 62, so that an inner pivot frame 80 which is closed all round is formed.

In der in FIG. 4 dargestellten Tiefstellung des Badewanneneinsatzes liegt der äußere Schwenkrahmen 72 auf den bodenseitigen Schienen 60 auf und der innere Schwenkrahmen 80 liegt zum äußeren Schwenkrahmen 72 niveaugleich, wobei die oberen Schienen 68 die Arme 50 des inneren Schwenkrahmens 80 berühren.In the in FIG. 4, the lower position of the bathtub insert is shown, the outer swivel frame 72 rests on the bottom rails 60 and the inner swivel frame 80 is level with the outer swivel frame 72, the upper rails 68 touching the arms 50 of the inner swivel frame 80.

Bezogen auf die mittlere Gelenkachse 52 hat der Arm 48 einen unteren Hebel 48a und einen oberen Hebel 48b und der Arm 50 hat einen unteren Hebel 50a und einen oberen Hebel 50b. Die beiden Hebellängen 50a und 48b sind gleich lang, sodaß die Schwenkachsen 54 und 62 aller vier Arme in Querrichtung ausgefluchtet sind, wenn sich der Badewanneneinsatz in der Tiefstellung befindet. Der untere Hebel 48a ist etwa 13% länger als die beiden gleich fangen Hebel 50a, 48b. Dadurch wird erreicht, daß die Sitzplatte 14 beim Hubvorgang sich gleichzeitig nach hinten verlagert und dabei die Sitzplatte 14 in eine nach hinten abwärts geneigte Schrägstellung bringt. Der Hebel 50b des Armes 50 ist etwa 9% kürzer als die beiden gleich langen Armhebel 50a, 48b. Dadurch wird die nach hinten gerichtete Abwärtsneigung der Sitzplatte 14 teilweise kompensiert, jedoch bleibt eine gewissen Abwärtsneigung erhalten, die für das sichere Sitzen günstig ist. Die verringerte Länge der Armhebel 50b gegenüber den Armhebeln 48a ermöglicht die Anordnung der Querstrebe 70 und damit die Bildung des äuBeren starren Rahmens 72, denn die Enden dieser Armhebel 50b liegen dicht benachbart der Querstrebe 70 etwa in der gleichen Ebene, wenn die Tiefstellung erreicht ist.The arm has relative to the central articulation axis 52 48 has a lower lever 48a and an upper lever 48b and the arm 50 has a lower lever 50a and an upper lever 50b. The two lever lengths 50a and 48b are of equal length, so that the pivot axes 54 and 62 of all four arms are aligned in the transverse direction when the bathtub insert is in the lowered position. The lower lever 48a is about 13% longer than the two levers 50a, 48b with the same catch. It is thereby achieved that the seat plate 14 is simultaneously displaced rearwards during the lifting process and thereby brings the seat plate 14 into an inclined position which is inclined downwards towards the rear. The lever 50b of the arm 50 is approximately 9% shorter than the two arm levers 50a, 48b of the same length. This partially compensates for the rearward downward inclination of the seat plate 14, but a certain downward inclination remains which is favorable for safe sitting. The reduced length of the arm levers 50b compared to the arm levers 48a enables the arrangement of the cross strut 70 and thus the formation of the outer rigid frame 72, because the ends of these arm levers 50b lie closely adjacent to the cross strut 70 in approximately the same plane when the lower position is reached.

Verschiedene Abwandlungen liegen im Rahmen der Erfindung. So kann das Wickelrohr 28 an der Unterseite der Sitzplatte gelagert werden, während die Befestigungsleiste 26 am Bodengestell befestigt wird. Auch kann bei dem Bodengestell 12 auf die dargestellte Bodenplatte verzichtet werden, wenn die Bodenschienen 60 durch Querschienen zu einem Bodenrahmen verbunden werden, an dem dann die Schwenklager 62, die Lagerböcke 36, 44 für die Wickeltrommel 28 und das bodenseitige Ende des Schlauches 18 befestigt werden.Various modifications are within the scope of the invention. So the winding tube 28 at the bottom of the Seat plate are stored while the mounting bar 26 is attached to the floor frame. The base plate shown can also be dispensed with in the base frame 12 if the base rails 60 are connected by transverse rails to form a base frame, to which the pivot bearings 62, the bearing blocks 36, 44 for the winding drum 28 and the bottom end of the hose 18 are then attached .
