Description

Die Erfindung betrifft einen Badewannenlifter mit abnehmbarer Rückenplatte.The invention relates to a bathtub lifter with a removable back plate.

Badewannenlifter dienen dazu, auch körperlich eingeschränkten Benutzern ein Bad zu ermöglichen oder ein solches zu erleichtern, indem sich diese auf eine auf angenehme Höhe gefahrene Sitzfläche des Badewannenlifters setzen und mit dieser behutsam in Richtung eines Badewannenbodens abgelassen werden.Bathtub lifters are used to enable physically handicapped users to take a bath or to make bathing easier by allowing them to sit on a seat of the bathtub lifter that is at a comfortable height and then gently lower them towards a bathtub floor.

Ein Badewannenlifter weist in seinem Grundaufbau hierzu eine Bodenplatte auf, die üblicherweise über Saugfüße beabstandet, auf einem Wannenboden aufliegt. Die Bodenplatte trägt eine Sitzplatte mit daran befestigter Rückenlehne, wobei die zwischen Boden- und Sitzplatte ein Scherensystem angeordnet ist. Die Rückenplatte ist relativ zur Sitzplatte in gewissen Winkeln verstellbar, um ein angenehmes Anlehnen eines Benutzers zu ermöglichen.In its basic structure, a bathtub lifter has a base plate for this purpose, which is usually spaced apart by suction feet and rests on a bathtub floor. The base plate carries a seat plate with a backrest attached to it, a scissors system being arranged between the base plate and the seat plate. The back plate is adjustable at certain angles relative to the seat plate in order to allow a user to lean comfortably.

An der Rückenplatte ist eine Verstellvorrichtung angeordnet, wie sie beispielsweise in der DE 10 2007 045 952 A1 beschrieben ist, und mit der sich der Abstand zwischen Sitz- und Bodenplatte einstellen läßt. Eine solche Verstellvorrichtung weist einen Antrieb und eine Kraftübertragung auf die Bodenplatte auf, beispielsweise in Form einer ein- und ausfahrbaren Zahnstange, einem Linearmotor oder anderem mehr. Über die Kraftübertragung drückt sich gleichsam die Sitzplatte über die Rückenlehne von der Bodenplatte bis zu einem maximalen Abstand ab. Ein maximaler Abstand entspricht in etwa der üblichen Badewannentiefe, sodass sich ein Benutzer auf den Badewannenlifter komfortabel wie auf einen Stuhl setzen kann, bevor er in Richtung Wannenboden zu einem minimalen Abstand von Sitzplatte zu Bodenplatte verfahren wird.An adjusting device is arranged on the back plate, as is for example in the DE 10 2007 045 952 A1 is described, and with which the distance between the seat and floor plate can be adjusted. Such an adjustment device has a drive and a power transmission to the base plate, for example in the form of an extendable and retractable rack, a linear motor or other means. Via the power transmission, the seat plate pushes itself over the backrest from the base plate up to a maximum distance. A maximum distance corresponds roughly to the usual bathtub depth, so that a user can sit comfortably on the bathtub lifter as if on a chair before moving towards the bathtub floor to a minimum distance from seat plate to floor plate.

Die Rückenplatten sind üblicherweise lösbar von der Sitzplatte, insbesondere bei spitzen Winkeln zwischen beiden, so dass ein Benutzerkörper auf der Sitzplatte ein versehentliches Lösen verhindernd ist. Beispielsweise sind Badewannenlifter bekannt, bei denen die Rückenlehne auf die Sitzplatte geklappt werden muss, um von dieser entfernbar zu sein. Üblicherweise trägt die Sitzplatte auf der Sitzflächenseite Kupplungseinrichtungen für die Verbindung mit der Rückenlehne. Mit den bekannten Rückenplatten ist es nicht in wünschenswertem Maße möglich, einem Benutzer ein entspanntes Zurücklehnen zu ermöglichen.The back panels are usually detachable from the seat panel, in particular at acute angles between the two, so that a user body on the seat panel prevents accidental detachment. For example, bathtub lifters are known in which the backrest must be folded onto the seat plate in order to be removable therefrom. The seat plate usually carries coupling devices on the seat surface side for connection to the backrest. With the known back plates, it is not possible to a desirable extent to allow a user to lean back and relax.

Im Stand der Technik sind weitere Badewannenlifter bekannt. Aus der DE 198 33 384 A1 ist ein Badewannenlifter bekannt, dessen Sperrvorrichtung aus Rastnoppen und dazu korrespondierende Rastausnehmungen besteht. Aus der DE 197 01 591 A1 ist ein Badewannenlifter mit einer an der Rückenlehne angeordneten und auf der Bodenplatte gelagerten Teleskopstange bekannt, bei der eine Sperrvorrichtung an der Sitzplatte angeordnet ist. Aus der DE 101 40 847 A1 ist ein Badewannenlifter mit einer Hubeinrichtung mit einer Antriebsvorrichtung bekannt. Aus der DE 41 30 323 A1 ist ein Badewannenlifter mit einer arretierbaren Rückenlehne bekannt.Further bathtub lifters are known in the prior art. From the DE 198 33 384 A1 a bathtub lifter is known whose locking device consists of locking knobs and corresponding locking recesses. From the DE 197 01 591 A1 a bathtub lifter is known with a telescopic rod arranged on the backrest and mounted on the base plate, in which a locking device is arranged on the seat plate. From the DE 101 40 847 A1 a bathtub lifter with a lifting device with a drive device is known. From the DE 41 30 323 A1 a bathtub lifter with a lockable backrest is known.

Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, einen Badewannenlifter mit einer sowohl benutzerfreundlichen als auch bedienerfreundlich entfernbaren Rückenplatte vorzuschlagen.The present invention is based on the object of proposing a bath tub lifter with a back plate that is both user-friendly and user-friendly removable.

Diese Aufgabe wird gelöst durch einen Badewannenlifter, aufweisend eine Bodenplatte, eine zu dieser abstandsveränderliche Sitzplatte, eine an der Sitzplatte lösbar angeordnete und relativ zu dieser bewegbare Rückenplatte, wobei die Rückenplatte eine angetriebene Verstellvorrichtung zur Verstellung des Abstandes zwischen Boden- und Sitzplatte aufweist und wobei eine Sperrvorrichtung zur Freigabe der Rückenplatte vorgesehen ist, wobei die Sperrvorrichtung nicht auf der von der Bodenplatte abgewandten Fläche der Sitzplatte angeordnet ist und ein Lösen der Rückenplatte nur in einer bodenplattenseitigen Endlage der Sitzplatte ermöglichend ist.This object is achieved by a bathtub lifter, having a base plate, a seat plate that can be spaced apart from this, a back plate which is detachably arranged on the seat plate and movable relative to it, the back plate being a driven adjustment device for adjusting the distance between the floor and the floor Has seat plate and wherein a locking device is provided for releasing the back plate, the locking device not being arranged on the surface of the seat plate facing away from the bottom plate and a release of the back plate only possible in a bottom plate-side end position of the seat plate.

Mit großem Vorteil ermöglicht die Erfindung sowohl ein komfortables Nutzen der gesamten Sitzplatte als Sitzfläche und ein völlig ungefährliches Entfernen der Rückenplatte durch eine Hilfsperson während der Benutzung des Badenwannenlifters, da dies nur in der tiefsten Stellung und damit sicher in der Badewanne erfolgen kann. Nach Entfernen der Rückenplatte steht einem Benutzer somit die gesamte Badewannenlänge hinter der Position des Badewannenlifters sowie die Rückenplatte der Badewanne selber zur Verfügung, er kann seine Sitzposition auf der gesamten Länge der Sitzplatte frei wählen, ohne dass ihn eine Sperrvorrichtung oder ein Gelenk auf dieser Fläche daran hindern könnten. Die Entfernbarkeit der Rückenplatte und damit -lehne nur in einer bodennahen Position der Sitzplatte ist erfindungsgemäße auf vielfältige Weise erreichbar: Beispielsweise mechanisch durch einen Sperrriegel, der nur in der bodenplattennächsten Position der Sitzplatte durch Kontakt zur Bodenplatte durch Verschwenken mechanisch entriegelnd ist, mechanisch durch einen Freigabestift in der Sitzplatte, der die Bodenplatte kontaktierend ist und sich beim Absenken der Sitzplatte linear in eine Freigabeposition begebend ist, elektronisch über einen Näherungs- oder Kontaktsensor, der eine Verriegelung motorisch freigebend ist und auf anderen Wegen mehr.With great advantage, the invention enables both a comfortable use of the entire seat plate as a seat and a completely safe removal of the back plate by an assistant while using the bathtub lifter, since this can only be done in the lowest position and thus safely in the bathtub. After removing the back plate, a user has the entire length of the bathtub behind the position of the bathtub lifter as well as the back plate of the bathtub itself at his disposal, he can freely choose his sitting position over the entire length of the seat plate without a locking device or a joint on this surface could prevent. The removability of the back plate and thus the backrest only in a position of the seat plate close to the floor can be achieved according to the invention in a variety of ways: for example mechanically by a locking bolt that is mechanically unlocked only in the position of the seat plate closest to the base plate by pivoting contact with the base plate, mechanically by means of a release pin in the seat plate, which is in contact with the base plate and moves linearly into a release position when the seat plate is lowered, electronically via a proximity or contact sensor that releases a lock by a motor and more in other ways.

In Ausgestaltung der Erfindung ist vorgesehen, dass die Sperrvorrichtung mindestens zwei Formschlußbauteile aufweist, deren Formschluß durch die Verstellvorrichtung herstell- und lösbar ist. Eine solche mechanische wirkende Sperrvorrichtung ist aufgrund der geringen konstruktiven, motorischen und elektronischen Anforderungen bevorzugt. Sie nutzt mit großem Vorteil die zur Höhenverstellung der Sitzplatte schon vorhandene Verstellvorrichtung und stellt so sicher, dass die Lösbarkeit nur in der bodenplattennächsten Position der Sitzplatte erfolgen kann. Die Verstellvorrichtung wirkt dabei insbesondere nicht unmittelbar auf die Formschlußelemente ein, sondern ist deren relative Lage zueinander verändernd, insbesondere, indem sie auf die Rückenplatte eine Kraft ausübend ist oder nicht.In an embodiment of the invention it is provided that the locking device has at least two positive locking components, the positive locking of which can be established and released by the adjusting device. Such a mechanical locking device is due to the low structural, motor and electronic requirements are preferred. It uses the adjustment device already present for height adjustment of the seat plate with great advantage and thus ensures that it can only be released in the position of the seat plate that is closest to the base plate. The adjusting device in particular does not act directly on the interlocking elements, but changes their relative position to one another, in particular by exerting a force on the back plate or not.

In Weiterbildung der Erfindung ist vorgesehen, dass ein Formschlußbauteil ein an der Sitzplatte angeordneter Sperrbolzen und ein weiteres Formschlußbauteil ein an der Rückenplatte angeordnete Durchgangsöffnung zur Durchsetzung durch den Sperrbolzen ist, wobei die Verstellvorrichtung eine relative Lage der beiden Formschlußteile zueinander verändernd ist. Wie bereits erläutert, ist dies eine konstruktiv einfache und bediensichere Ausführung, bei der, insbesondere durch Kraftausübung auf die Rückenplatte, die Lage der beiden Formschlußteile zueinander veränderbar ist, vorzugsweise derart, dass eine Längsachse des Sperrbolzens entweder koaxial oder nicht-koaxial zur Durchgangsöffnung ist.In a further development of the invention it is provided that a form-locking component is a locking bolt arranged on the seat plate and a further form-locking component is a through opening arranged on the back plate for penetration through the locking bolt, the adjustment device changing a relative position of the two form-locking parts to one another. As already explained, this is a structurally simple and reliable design in which, in particular by exerting force on the back plate, the position of the two interlocking parts can be changed, preferably such that a longitudinal axis of the locking pin is either coaxial or non-coaxial with the through opening.

Ist der Sperrbolzen gegen eine Kraft linear bewegbar parallel zu der Fläche der Sitzplatte ausgebildet, so ist mit großem Vorteil eine sichere Führung ermöglicht als auch eine einfache Anordnung im Material der Sitzplatte, da so deren gesamte Dicke zur Verfügung steht.If the locking bolt is designed so that it can move linearly against a force parallel to the surface of the seat plate, a secure guidance is made possible with great advantage and also a simple arrangement in the material of the seat plate, since its entire thickness is available in this way.

In Ausgestaltung der Erfindung ist vorgesehen, dass Sitzplatte und Rückenplatte jeweils gekrümmte Gleitflächen mit korrespondierenden Radien aufweisen, wobei die Gleitfläche der Sitzplatte länger als die Gleitfläche der Rückenplatte ausgebildet ist. Mit dieser vorteilhaften Ausgestaltung ist eine Entriegelungsposition der beiden Formschlußelemente zueinander bei gleichzeitiger variabler Fügeposition von Rücken- und Sitzplatte definiert. Erfindungsgemäß weist die Gleitfläche der Sitzplatte einen bestimmten Abstand zur Längsachse des Sperrbolzens auf und die Gleitfläche der Rückenplatte einen bestimmten Abstand zur Durchgangsöffnung, wobei beide Abstände so gewählt sind, dass die Formschlußbauteile koaxial sind, wenn die Gleitflächen einander flächig kontaktierend sind. In dieser Position ist die Rückenplatte an die Sitzplatte koppel- oder entkoppelbar, wobei der Fügewinkel zwischen beiden im Rahmen der umfänglichen Länge der gebogenen Gleitflächen von einer Hilfsperson frei wählbar ist. Eine Änderung der Lage der Gleitflächen zueinander, beispielsweise durch Vergrößerung des Abstandes der Rückenplatte zur Sitzplatte, wie sie bei Betätigung der Verstellvorrichtung auftritt, ist mit großem Vorteil die Formschlußbauteile verriegelnd, da die Koaxialität aufgehoben ist. Mit anderen Worten ist die erfindungsgemäße Rückenplatte in einem großem Winkelbereich mit der Sitzplatte koppelbar, solange die Sitzplatte in ihrer bodenplattennächsten Position befindlich ist, also mit unwirksamer Verstellvorrichtung.In an embodiment of the invention it is provided that the seat plate and the back plate each have curved sliding surfaces with corresponding radii, the sliding surface of the seat plate being longer than the sliding surface of the back plate. With this advantageous embodiment there is an unlocking position of the two Positive locking elements to each other with simultaneous variable joining position of back and seat plate defined. According to the invention, the sliding surface of the seat plate is at a certain distance from the longitudinal axis of the locking bolt and the sliding surface of the back plate is a certain distance from the through opening, both distances being selected so that the form-locking components are coaxial when the sliding surfaces are in flat contact with one another. In this position, the back plate can be coupled or decoupled from the seat plate, the joining angle between the two being freely selectable by an assistant within the scope of the circumferential length of the curved sliding surfaces. A change in the position of the sliding surfaces to one another, for example by increasing the distance between the back plate and the seat plate, as occurs when the adjustment device is actuated, is of great advantage in locking the positive-locking components, since the coaxiality is eliminated. In other words, the back plate according to the invention can be coupled to the seat plate in a large angular range as long as the seat plate is in its position closest to the base plate, that is to say with an ineffective adjustment device.

In Weiterbildung der Erfindung ist vorgesehen, dass die Sitzplatte wenigstens einen Anschlag für die Rückenplatte aufweist, insbesondere einen vorderen Anschlag. Unter einem vorderen Anschlag wird erfindungsgemäß ein solcher verstanden, der einen geringstmöglichen Winkel zwischen Sitz- und Rückenplatte definiert, beispielsweise 95°, 100° oder 105°.In a further development of the invention it is provided that the seat plate has at least one stop for the back plate, in particular a front stop. According to the invention, a front stop is understood to be one which defines the smallest possible angle between the seat and back panels, for example 95 °, 100 ° or 105 °.

Ist die Durchgangsöffnung in einem Arm der Rückenplatte angeordnet, so ist konstruktiv einfach eine Anordnung der Sperrvorrichtung unterhalb der Sitzfläche erreichbar, insbesondere im Bereich der Dicke der Sitzplatte, da die Arme die Sitzplatte entsprechend umgreifend sind.If the through opening is arranged in an arm of the back plate, an arrangement of the locking device below the seat surface can be achieved in a structurally simple manner, in particular in the area of the thickness of the seat plate, since the arms accordingly encompass the seat plate.

In Ausgestaltung der Erfindung ist vorgesehen, dass der Arm eine Aufgleitfläche zur Betätigung des Sperrbolzens aufweist. Diese Aufgleitfläche ermöglicht mit großem Vorteil ein Aufsetzen der Rückenplatte von oben auf die Sitzplatte mit automatischem Eindrücken des Sperrbolzens gegen eine Kraft, insbesondere Federkraft.In an embodiment of the invention it is provided that the arm has a sliding surface for actuating the locking bolt. This sliding surface enables the back plate to be placed on the seat plate from above with great advantage, with the locking pin being automatically pushed in against a force, in particular a spring force.

Mit ganz großem Vorteil ist in Weiterbildung der Erfindung vorgesehen, dass die Verstellvorrichtung mindestens eine, bevorzugt zwei Zahnstangen aufweist. Anstelle der bekannten, einen Zahnstange der Verstellvorrichtung weisen zwei Zahnstangen einen deutlichen Vorteil hinsichtlich der Stabilität des Badewannenlifters auf. Da sie an zwei zueinander beabstandeten Stellen und nicht mehr nur an einer zentralen Stelle auf die Bodenplatte drückend sind, sind sie die Gewichtskraft des Benutzers besser auf die Bodenplatte verteilend. Insbesondere liegen die Krafteinleitungspunkte näher an oder nahebei den Saugfüßen der Bodenplatte, so dass die Gewichtskraft schonender in die Bodenplatte eingeleitet ist. Ein Durchbiegen der Bodenplatte und schlimmstenfalls ein punktuelles Aufsetzen der Bodenplatte auf den Wannenboden sind vermieden, die Gefahr des Brechens des Wannenbodens gebannt.In a development of the invention, it is provided with great advantage that the adjusting device has at least one, preferably two, toothed racks. Instead of the known, one toothed rack of the adjusting device, two toothed racks have a clear advantage with regard to the stability of the bathtub lifter. Since they are pressing on the base plate at two mutually spaced points and no longer just at a central point, they are better able to distribute the weight of the user on the base plate. In particular, the force introduction points are closer to or close to the suction feet of the base plate, so that the weight force is introduced into the base plate more gently. Bending of the base plate and, in the worst case, a punctual placement of the base plate on the tub bottom are avoided, and the risk of the tub bottom breaking is avoided.

Dies gilt umso mehr, als sich die Zahnstangen an der Bodenplatte abstützend sind, insbesondere geführt abstützend sind.This is all the more true as the racks are supported on the base plate, in particular are supported in a guided manner.

Schließlich ist erfindungsgemäß vorgesehen, dass die Rückenplatte in einem Winkel zur Sitzplatte zwischen 90° und 150°, insbesondere zwischen 100° und 140° anordenbar ist.Finally, it is provided according to the invention that the back plate can be arranged at an angle to the seat plate between 90 ° and 150 °, in particular between 100 ° and 140 °.

Die Erfindung wird in einer bevorzugten Ausführungsform unter Bezugnahme auf folgende Figuren beispielhaft beschrieben, wobei weitere vorteilhafte Einzelheiten den Figuren zu entnehmen sind. Funktionsmäßig gleiche Teile sind dabei mit den gleichen Bezugszeichen versehen.The invention is described by way of example in a preferred embodiment with reference to the following figures, further advantageous details being shown in the figures.

Fig. 1 zeigt eine schematische Ansicht eines erfindungsgemäßen Badewannenlifters 1. Der Badewannenlifter 1 besteht im Wesentlichen aus einer Bodenplatte 2, welche im Benutzungsfall auf dem Badewannenboden aufliegend, bzw. mittels Füßen von ihm beabstandet ist, eine Sitzplatte 3 für einen Benutzer, ein Scherensystem 16 zur möglichst stabilen Kraftübertragung von der benutzten Sitzplatte 3 zur Bodenplatte 2 und einer Rückenplatte 4, welche eine angetriebene Verstellvorrichtung 5 tragend ist. Diese Verstellvorrichtung 5 ist entweder motorisch, insbesondere elektromotorisch, oder manuell angetrieben ausgebildet und bewirkt eine insbesondere vertikale Verstellung der Sitzplatte relativ zur Bodenplatte. Die Verstellvorrichtung 5 ist dabei erfindungsgemäß entweder auf das Scherensystem 16 oder auf die Bodenplatte wirkend, insbesondere mittels einer Zahnstange 15 auf die Bodenplatte. Indem die Zahnstange 15 - oder eine entsprechende Vorrichtung wie ein Linearmotor - entlang des Doppelpfeils ein- oder ausgefahren wird, verändert sie den Abstand zwischen Bodenplatte 2 und Sitzplatte 3. In eingefahrenem Zustand der Zahnstange 15 befindet sich die Sitzplatte 3 in einer bodenplattennahen Position, im ausgefahrenen Zustand in einer bodenplattenferneren Position, wobei die Zahnstange 15 im ersten Fall die Bodenplatte 2 nicht kontaktierend oder mindestens nicht mit Kraft beaufschlagend ist. Fig. 1 shows a schematic view of a bathtub lifter 1 according to the invention. The bathtub lifter 1 consists essentially of a base plate 2 which, when in use, rests on the bathtub floor or is spaced from it by means of feet, a seat plate 3 for a user, a scissor system 16 for the most stable possible Power transmission from the seat plate 3 used to the base plate 2 and a back plate 4, which supports a driven adjustment device 5. This adjusting device 5 is designed either to be motor-driven, in particular by an electric motor, or to be driven manually, and it effects a particularly vertical adjustment of the seat plate relative to the base plate. According to the invention, the adjusting device 5 acts either on the scissors system 16 or on the base plate, in particular by means of a toothed rack 15 on the base plate. As the rack 15 - or a corresponding device such as a linear motor - is retracted or extended along the double arrow, it changes the distance between the base plate 2 and seat plate 3. In the retracted state of the rack 15, the seat plate 3 is in a position close to the base plate, in extended state in a position further away from the base plate, the toothed rack 15 in the first case not making contact with the base plate 2 or at least not applying force.

Die Sitzplatte 3 ist auf der oberen, von der Bodenplatte 2 abgewandten, Seite - der Sitzfläche - erfindungsgemäß weitestgehend flach und ergonomisch ausgestaltet, sodass sowohl ein Sitzen als auch ein Liegen des Benutzers auf der Sitzplatte 3 ohne Komforteinbußen ermöglicht ist. Erfindungsgemäß ist keine Erhöhung auf dieser Seite vorgesehen, wie sie im Stand der Technik zur Verbindung mit der Rückenplatte 4 vorgesehen ist.The seat plate 3 is designed largely flat and ergonomically on the upper side facing away from the base plate 2 - the seat surface - according to the invention, so that the user can both sit and lie on the seat plate 3 without sacrificing comfort. According to the invention, no elevation is provided on this side, as is provided in the prior art for connection to the back plate 4.

Die Rückenplatte 4 ist lösbar an der Sitzplatte 3 angeordnet und zu dieser verschwenkbar.The back plate 4 is detachably arranged on the seat plate 3 and can be pivoted relative to it.

Fig. 2 zeigt in vier Teilfiguren eine erste Ausführungsform der Erfindung. Fig. 2 shows a first embodiment of the invention in four partial figures.

In Fig. 2a ist in schematischer Seitenansicht eine Sitzplatte 3 mit angelenkter Rückenplatte 4 in zwei Winkelstellungen zur Sitzplatte 3 dargestellt. Die Fläche 7 bildet die Sitzfläche, die glatt, plan oder ergonomisch geformt ist. Zu erkennen ist die Sperrvorrichtung 6, die bei diesem Ausführungsbeispiel seitlich angeordnet ist, so dass die Rückenplatte 4 die Sitzplatte 3 mit zwei Armen 13 umgreifend ist. Obwohl diese Anordnung bevorzugt ist, wäre auch eine Anordnung der Sperrvorrichtung innerhalb oder unterhalb der Sitzplatte erfindungsgemäß. Zu erkennen ist ein Sperrbolzen 8' als Formschlußteil 8 und eine Durchgangsöffnung 9' als Formschlußteil 9, die jeweils Teil der Sperrvorrichtung sind. Diese Position ist in Fig. 2b genauer dargestellt.In Fig. 2a a seat plate 3 with an articulated back plate 4 is shown in two angular positions to the seat plate 3 in a schematic side view. The surface 7 forms the seat, which is smooth, flat or ergonomically shaped. The locking device 6 can be seen, which is arranged laterally in this exemplary embodiment, so that the back plate 4 encompasses the seat plate 3 with two arms 13. Although this arrangement is preferred, an arrangement of the locking device inside or below the seat plate would also be according to the invention. A locking bolt 8 'can be seen as a form-fit part 8 and a through opening 9' as a form-fit part 9, which are each part of the locking device. This position is in Figure 2b shown in more detail.

In Fig. 2b ist die koaxiale Anordnung von Sperrbolzen 8' und Durchgangsöffnung 9' zu erkennen. In dieser Anordnung ist die Sperrvorrichtung 6 entriegelbar, indem der Sperrbolzen 8' gegen eine Kraft in Richtung auf die Sitzplatte gedrückt wird, woraufhin die Rückenplatte 4 abgenommen werden kann. Die dargestellte Position entspricht dabei einer bodenplattennächsten Position der Sitzplatte 3 mit eingefahrener Zahnstange, bzw. mit einer Zahnstange in einer Position, in der sie keine Kraft mehr auf die Bodenplatte ausübend ist.In Figure 2b the coaxial arrangement of locking pin 8 'and through opening 9' can be seen. In this arrangement, the locking device 6 can be unlocked in that the locking bolt 8 'is pressed against a force in the direction of the seat plate, whereupon the back plate 4 can be removed. The position shown corresponds to a position of the seat plate 3 that is closest to the base plate retracted rack, or with a rack in a position in which it no longer exerts any force on the base plate.

Zu erkennen sind weiterhin zwei Anschläge 12 sowie eine gebogene Gleitfläche 10 der Sitzplatte 3 und eine korrespondierend gebogene Gleitfläche 11 der Rückenplatte 4. Dargestellt ist eine Stellung der Rückenplatte 4 in der diese mit der Sitzplatte 3 einen größtmöglichen stumpfen Winkel einschließt, insbesondere 140°. Der vordere Anschlag 12 begrenzt die untere Grenze des Winkels, insbesondere auf 100°. Mit großem Vorteil ermöglicht die Erfindung so einen vorderen Anschlag, der die Stabilität der Vorrichtung erhöht. In diesem Winkelbereich ist die Rückenplatte 4 mit der Sitzplatte 3 verbind- und lösbar. Eine Hilfsperson muß daher mit großem Vorteil nicht erst eine bestimmte Winkelstellung suchen, vielmehr reicht eine ungefähre Winkelstellung aus, um beide Teile miteinander zu verbinden oder voneinander zu lösen.Two stops 12 as well as a curved sliding surface 10 of the seat plate 3 and a correspondingly curved sliding surface 11 of the back plate 4 can also be seen. A position of the back plate 4 is shown in which it forms the largest possible obtuse angle with the seat plate 3, in particular 140 °. The front stop 12 limits the lower limit of the angle, in particular to 100 °. With great advantage, the invention thus enables a front stop which increases the stability of the device. In this angular range, the back plate 4 can be connected to and released from the seat plate 3. It is therefore very advantageous for an assistant not to first look for a specific angular position, rather an approximate angular position is sufficient to connect the two parts to one another or to detach them from one another.

Fig. 2c zeigt die verriegelte Stellung in einer Detailansicht. Diese Stellung wird automatisch eingenommen, sobald die Verstellvorrichtung die Sitzplatte 3 von der Bodenplatte entfernt, sie also angehoben hat. Die Sitzplatte 3 wird dabei von der Rückenplatte 4 hochgezogen, die die ihrerseits die mit einem Antrieb 17 versehene Verstellvorrichtung 5 trägt, mit der über die ausfahrende Zahnstange 15 auf die Bodenplatte 2 drückt (siehe Fig. 1). Erfindungsgemäß ist die Durchgangsöffnung 13 mit zwei axialen Abschnitten mit unterschiedlichem Radius ausgebildet, wobei auch der kleinere Radius größer ist als der Radius des Sperrbolzens 8'. Hierdurch ergibt sich ein radiales Spiel des Sperrbolzens 8' in der Durchgangsöffnung 9', so dass die Rückenplatte 4 im Maß dieses Spiels von der Sitzplatte 3 abhebbar oder allgemeiner entfernbar ist. Dies ist auch an der Beabstandung zwischen den beiden Gleitflächen 10, 11 zu erkennen. Mit anderen Worten ist ein Entfernen der Rückenplatte nur dann ermöglicht, wenn die Sitzplatte dichtestmöglich an der Bodenplatte angeordnet ist, sich ein Benutzer also bereits in einer Badewanne befindet und durch die Badewannenwände gesichert ist. Dies bedeutet auch, dass die Sitzplatte 3 an den Sperrbolzen 8' hochgezogen wird, die daher entsprechend dimensioniert sind. Figure 2c shows the locked position in a detailed view. This position is assumed automatically as soon as the adjustment device has removed the seat plate 3 from the base plate, ie has raised it. The seat plate 3 is pulled up by the back plate 4, which in turn carries the adjusting device 5, which is provided with a drive 17 and with which presses on the base plate 2 via the extending rack 15 (see FIG Fig. 1 ). According to the invention, the through opening 13 is formed with two axial sections with different radii, the smaller radius also being larger than the radius of the locking pin 8 '. This results in a radial play of the locking pin 8 'in the through opening 9', so that the back plate 4 can be lifted off the seat plate 3 or, more generally, removed to the extent of this play. This can also be seen from the spacing between the two sliding surfaces 10, 11. In other words, the back plate can only be removed if the seat plate is as close as possible to the base plate is arranged, so a user is already in a bathtub and is secured by the bathtub walls. This also means that the seat plate 3 is pulled up on the locking bolts 8 ', which are therefore dimensioned accordingly.

Fig. 2d zeigt eine teilweise geschnittene Rückansicht der erfindungsgemäßen Vorrichtung im Bereich der Verbindung von Rücken- und Sitzplatte. Fig. 2d shows a partially sectioned rear view of the device according to the invention in the area of the connection of the back and seat plate.

Zu erkennen ist der radial gestufte axiale Verlauf der Durchgangsöffnung 9' mit einem radial größeren, äußeren und einem radial kleineren, inneren axialen Abschnitt. Beide Abschnitte sind durchmessergrößer als der Sperrbolzen 8', der an seinem äußeren Ende wiederum durchmessergrößer als an seinem inneren Ende ausgebildet ist. Diese Ausgestaltung der Durchgangsöffnung 9' ermöglicht ein Eindrücken und ein Verschieben des Sperrbolzens 8' in eine verriegelte Position, wie sie hier dargestellt ist. Zu erkennen ist weiter der in der Sitzplatte 3 in einer Bohrung aufgenommene Sperrbolzen 8' sowie eine Feder 18, insbesondere eine Spiralfeder, die auf den dargestellten Sperrbolzen 8' wirkend ist und gegen deren Kraft der Sperrbolzen 8' in seine zurückgezogene Freigabeposition verbringbar ist. Anstelle der dargestellten Feder 18 ist auch jeder andere elastische Körper erfindungsgemäß, beispielsweise ein Elastomerkörper.The radially stepped axial profile of the through opening 9 'can be seen with a radially larger, outer and a radially smaller, inner axial section. Both sections are larger in diameter than the locking pin 8 ', which is in turn formed with a larger diameter at its outer end than at its inner end. This configuration of the through opening 9 'enables the locking pin 8' to be pressed in and moved into a locked position, as shown here. The locking pin 8 'received in a bore in the seat plate 3 and a spring 18, in particular a spiral spring, which acts on the locking pin 8' shown and against whose force the locking pin 8 'can be brought into its retracted release position can also be seen. Instead of the illustrated spring 18, any other elastic body is also according to the invention, for example an elastomer body.

In einer alternativen und nicht dargestellten Ausführungsform ist der Sperrbolzen 8' zentral, insbesondere aber per Knopfdruck einziehbar ausgestaltet. Das Einziehen kann dabei durch einen Elektromotor oder aber auch beispielsweise mechanisch über eine Gelenkstange oder ähnlichem geschehen. Dies hat den Vorteil, dass ein direkter Zugang zur in der Badewanne befindlichen Sperrvorrichtung nicht erforderlich ist, ein Eingreifen in das Badewasser durch die Hilfsperson wird mit Vorteil vermieden.In an alternative and not shown embodiment, the locking bolt 8 'is designed centrally, but in particular retractable at the push of a button. The retraction can be done by an electric motor or, for example, mechanically by means of a joint rod or the like. This has the advantage that direct access to the locking device located in the bathtub is not required Intervention in the bath water by the assistant is advantageously avoided.

Am unteren Ende eines Arms 13 der Rückenplatte 4 ist eine Aufgleitfläche 14 angeordnet, die ein Eindrücken des Sperrbolzens 8' bei einem Koppeln der Rückenplatte 5 mit der Sitzplatte 3 automatisch bewirkend ist. Beim Einführen der Rückenplatte 4 von oben wird der Sperrbolzen 8' durch die Aufgleitfläche 14 eingedrückt und springt, sobald die Rückenplatte 4 so weit auf die Sitzplatte 3 geschoben ist, dass sich die Durchgangsöffnung 9' über dem Sperrbolzen 8' befindet, in eine beide Platten aneinander verriegelnde Position zurück.At the lower end of an arm 13 of the back plate 4 there is a sliding surface 14 which automatically causes the locking pin 8 'to be pressed in when the back plate 5 is coupled to the seat plate 3. When the back plate 4 is inserted from above, the locking bolt 8 'is pressed in by the sliding surface 14 and, as soon as the back plate 4 is pushed so far onto the seat plate 3 that the through opening 9' is above the locking bolt 8 ', jumps into one of the two plates interlocking position.

Dargestellt ist ebenfalls eine Zahnstange 15, ein Antrieb 17 sowie dazwischen angeordnete Zahnräder 19, die zum einen als Übersetzung und zum anderen als Kraftübertragung von dem Antrieb 17 auf die Zahnstange 15 dienend sind. Mit besonders großem Vorteil sind bei dieser Ausführungsform zwei Zahnstangen 15 vorgesehen, so dass sich aufgrund ihrer zueinander beabstandeten Aufstandspunkte auf der Bodenplatte in der Nähe der Füße ein besonders stabiler Badenwannenlifter mit höchsten Nutzungskomfort ergibt.Also shown is a toothed rack 15, a drive 17 and toothed wheels 19 arranged in between, which are used on the one hand as a translation and on the other hand as a power transmission from the drive 17 to the toothed rack 15. With a particularly great advantage, two toothed racks 15 are provided in this embodiment, so that a particularly stable bathtub lifter with the highest level of convenience results due to their mutually spaced contact points on the base plate in the vicinity of the feet.

Fig. 3 zeigt die erfindungsgemäße Anordnung der beiden Zahnstangen 15 sowie des Antriebes 17 der Verstellvorrichtung 5 mit den entsprechenden Zahnrädern 19, die als Übersetzung zwischen der Drehzahl des Antriebes, eines Elektromotors, und der gewünschten Vorschubgeschwindigkeit der Zahnstangen dient. Das Vorsehen von zwei außermittigen Zahnstangen 15 anstelle einer einzigen, mittigen Zahnstange hat bei schwierigeren Antriebssituation gleich zwei Vorteile, nämlich die bessere Verteilung der auf der nicht dargestellten Sitzplatte angeordneten Last auf die ebenfalls nicht dargestellte Bodenplatte, so dass die Gefahr eines Durchbiegens der Bodenplatte womöglich bis auf den Wannenboden minimiert ist und so dass die Krafteinleitung näher an den wannenseitigen Füßen der Bodenplatte erfolgend ist. Gleichzeitig können die einzelnen Zahnstangen geringer dimensioniert sein als im Falle einer einzigen, mittigen Zahnstange. Anstelle der bei diesem Ausführungsbeispiel dargestellten Zahnstangen ist auch jede andere Ausführungsform erfindungsgemäß, die zwei in ihrer wirksamen Länge veränderliche Bauteile aufweist, beispielsweise Teleskoprohre, Linearantriebe und dergleichen mehr. Fig. 3 shows the inventive arrangement of the two racks 15 and the drive 17 of the adjusting device 5 with the corresponding gears 19, which serves as a translation between the speed of the drive, an electric motor, and the desired feed speed of the racks. The provision of two eccentric racks 15 instead of a single, central rack has two advantages in difficult drive situations, namely the better distribution of the load arranged on the seat plate, not shown, to the floor plate, also not shown, so that the risk of the floor plate sagging up to is minimized to the tub bottom and so that the introduction of force is closer to the tub-side feet of the base plate. At the same time, the individual racks can be dimensioned smaller than in the case of a single, central rack. Instead of the toothed racks shown in this exemplary embodiment, any other embodiment is also according to the invention which has two components whose effective length is variable, for example telescopic tubes, linear drives and the like.

Die Erfindung stellt mit großem Vorteil einen Badewannenlifter zur Verfügung, dessen Rückenplatte nur in einer sicheren Betriebsposition von der Sitzplatte lösbar ist und dessen Sitzplatte aufgrund fehlender störender Bauteile eine glatte und gänzlich nutzbare Sitzplatte aufweist, so dass ein Benutzer eine möglichst liegende Stellung in einer Badewanne einnehmen kann Hierbei ist die Rückenplatte erfindungsgemäß auch dann von der Sitzplatte entfernbar, wenn auf dieser ein Benutzer sitzt, sofern sie sich in einer untersten Position nahe des Wannenbodens befindet.The invention provides a bathtub lifter with great advantage, the back plate of which can only be detached from the seat plate in a safe operating position and the seat plate of which, due to the lack of interfering components, has a smooth and fully usable seat plate, so that a user can assume a position in a bathtub that is as recumbent as possible Here, according to the invention, the back plate can also be removed from the seat plate when a user is sitting on it, provided it is in a lowermost position near the tub bottom.
