Abstract

A raising plate (14) is supported by two guide arrangements (16) in the form of pivot frames (18, 20) connected to one another in a hinged manner. In the raised position of the plate (14), the pivot frames (18, 20) are so upright that the slide bearings (28, 34) of the pivot frames (18, 20) tend to jam in the rails (30) guiding them. If the raising arrangement is activated so as to effect a lowering movement of the plate (14), the plate (14) would retain its height position on account of the tendency of the slide bearings (28, 34) to jam. This tendency to jam is overcome by virtue of a spring arrangement (36) engaging in the area of the upper pivot bearing (34) of at least one guide arrangement (16). <IMAGE>

Description

Die Erfindung betrifft einen Badewanneneinsatz mit einem Bodengestell, einer Hubplatte, mindestens einer dazwischen angeordneten Führungseinrichtung sowie Hubeinrichtungen, wobei die Führungseinrichtung jeweils zwei scherenartig miteinander gelenkig verbundene Schwenkrahmen aufweist, die jeweils zwei koaxiale Festlager am Bodengestell bzw. der Hubplatte und jeweils zwei ebenfalls koaxiale Schiebelager an Hubplatte bzw. Bodengestell aufweisen und wobei an mindestens einem Schwenkrahmen der Führungseinrichtung eine Federanordnung mindestens in der letzten Schwenkphase des Schwenkrahmens bei der Aufwärtsbewegung der Hubplatte angreift. Die Hubplatte muß auf das Niveau des Badewannenrandes angehoben sein, wenn eine körperlich behinderte Person auf die Hubplatte gelangen will. Mit der Person wird die Hubplatte dann in die Badestellung abgesenkt.The invention relates to a bathtub insert with a floor frame, a lifting plate, at least one guide device arranged in between, and lifting devices, the guide device each having two scissor-like pivot frames that each have two coaxial fixed bearings on the floor frame or lifting plate and two coaxial sliding bearings Have lifting plate or floor frame and wherein at least one pivot frame of the guide means engages a spring arrangement at least in the last pivoting phase of the pivot frame during the upward movement of the lifting plate. The lifting plate must be raised to the level of the bath tub rim if a physically disabled person wants to get onto the lifting plate. The lifting plate is then lowered into the bathing position with the person.

Solche Badewanneneinsätze zeigen die DE-A-3324294 und die US-A-4,660,234. Tiefe Badewannen erfordern einen großen Hub der Hubplatte. Die Schwenkrahmen gelangen in so steile Stellungen, daß eine Selbstklemmung eintreten kann, insbesondere, wenn die Schiebelager in Schienen geführte Gleitstücke aufweisen. Die Hubplatte wird dann nicht mehr von der Hubeinrichtung gestützt und kann zu irgend einem Zeitpunkt schlagartig herabfallen, wenn durch eine Bewegung der von der Hubplatte getragenen Person die Selbstklemmung verloren geht.Such bathtub inserts are shown in DE-A-3324294 and US-A-4,660,234. Deep bathtubs require a large lift of the lifting plate. The swivel frames come into such steep positions that self-clamping can occur, especially if the sliding bearings have slide elements guided in rails. The lifting plate is then no longer supported by the lifting device and can drop suddenly at any point in time if the movement of the person carried by the lifting plate loses self-locking.

Man könnte zwar die Schwenkrahmen länger machen, doch müßten dann auch die Hubplatte und das Bodengestell verlängert werden, was bei kurzen Badewannen nicht möglich ist.You could make the swivel frame longer, but you would have to then the lifting plate and the base frame can be extended, which is not possible with short bathtubs.

Aufgabe der Erfindung ist es, einen Badewanneneinsatz zu schaffen, bei dem die Hubplatte mit steil stehenden Schwenkrahmen aus der angehobenen Position ruckfrei abgesenkt werden kann.The object of the invention is to provide a bathtub insert in which the lifting plate can be lowered smoothly from the raised position with the swivel frame standing upright.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Federanordnung auf diesen Schwenkrahmen ein seiner Aufwärts-Schwenkbewegung entgegenwirkendes Schwenkmoment ausübt, so das die größe gespeicherte Federkrafs bei Beginn der Absenkbewegung der Hubplatte zur Verfügung steht.This object is achieved in that the spring arrangement exerts a pivoting moment counteracting its upward pivoting movement on this pivoting frame, so that the stored spring force is available at the beginning of the lowering movement of the lifting plate.

Zwar ist aus der GB-A-2156210 ein Badewanneneinsatz ohne Bodengestell und mit einer horizontal unter der Hubplatte angeordneten Hubeinrichtung bekannt, bei der eine Federanordnung in Form von ein oder zwei Zugfedern vorgesehen ist, die die oberen Schiebelager-Enden der Schwenkrahmen zu den oberen Festlager-Enden hinziehen. Die Ferderanordnung zieht die Hubplatte nach oben. In einer Steilstellung der Schwenkrahmen würde die Federanordnung eine Selbstklemmung eher unterstützen.From GB-A-2156210 a bathtub insert without a base frame and with a lifting device arranged horizontally under the lifting plate is known, in which a spring arrangement in the form of one or two tension springs is provided, which connects the upper sliding bearing ends of the swivel frame to the upper fixed bearing - Drag ends. The remote arrangement pulls the lifting plate up. In a steep position of the swivel frame, the spring arrangement would rather support self-clamping.

Aus der US-A-3,106,723 ist ein Badewanneneinsatz bekannt, bei dem die unteren Enden der Schwenkrahmen ortsfest und die oberen Enden verschiebbar sind. Die Hubplatte ist über eine Federanordnung mit den oberen Enden beider Schwenkrahmen so verbunden, daß sie in einer Mittelposition gehalten wird. Die Federanordnung zieht auch hier die Hubplatte nach oben.A bathtub insert is known from US-A-3,106,723, in which the lower ends of the swivel frame are stationary and the upper ends are displaceable. The lifting plate is connected via a spring arrangement to the upper ends of both swivel frames so that it is held in a central position. The spring arrangement also pulls the lifting plate up here.

Demgegenüber wird die Federanordnung gemäß der Erfindung während der Aufwärtsbewegung der Hubplatte gespannt. Die größte gespeicherte Federkraft steht bei Beginn der Absenkbewegung der Hubplatte zur Verfügung und wirkt in Richtung des Abwärtsschwenkens der Schwenkrahmen, wobei ein mögliches Verklemmen der Schiebelager verhindert wird. Vorteilhafterweise wirkt die Kraft der Federanordnung in Richtung der Schiebebewegung der Schiebelager, weil dann mit geringster Federkraft eine maximale Wirkung erreicht wird.In contrast, the spring arrangement according to the invention is tensioned during the upward movement of the lifting plate. The greatest stored spring force is available at the start of the lowering movement of the lifting plate and acts in the direction of the downward swiveling of the swivel frame, preventing possible jamming of the sliding bearings. The force of the spring arrangement advantageously acts in the direction of the sliding movement of the sliding bearings, because then a maximum effect is achieved with the lowest spring force.

Die Federanordnung kann z.B. als Blatt- oder Schenkelfeder ausgebildet sein und im Gelenkbereich der beiden Schwenkrahmen montiert werden, derart, daß sich die Feder bei Verkleinerung des Winkels zwischen beiden Rahmen spannt. Auch liegt es im Rahmen der Erfindung, eine Zugfeder z.B. in Form eines starken Gummibandes zu verwenden, das an dem, den Schiebelagern zugeordneten Schenkel eines Schwenkrahmens befestigt wird und mit seinem anderen Ende an einem festen Punkt der Hubplatte bzw. des Bodengestells so befestigt wird, daß die Schiebelager von ihren Festlagern weggezogen werden. Eine besonders bevorzugte Ausführung der Erfindung besteht darin, daß die Federanordnung eine gerade Stange aufweist, auf der eine Schraubendruckfeder angeordnet ist, die an einem Ende gegen einen Kopf der Stange drückt, welcher einen Anschlag für den Schiebelagerbereich des Schwenkrahmens bildet und daß das andere Ende der Stange in einer Bohrung oder einem Kanal eines Befestigungsbeschlages axial verschiebbar geführt ist, der eine Vorderfläche und eine Hinterfläche aufweist und sich die Bohrung bzw. der Kanal zwischen Vorder- und Hinterfläche erstreckt und daß das andere Ende der Schraubendruckfeder sich an der Vorderfläche abstützt und ein am anderen Ende der Stange vorgesehener Fuß die Hinterfläche des Befestigungsbeschlages hintergreift. Vorzugsweise ist die Schraubendruckfeder vorgespannt, sodaß sich auch der Fuß der Stange an der Hinterfläche des Befestigungsbeschlages abstützt. Dieser Befestigungsbeschlag ist vorzugsweise innerhalb einer Schiene untergebracht, die auch ein Schiebelager eines Schwenkrahmens führt. Das Schiebelager bzw. ein von diesem bewegter Mitnehmer tritt somit bei der letzten Schwenkphase des Schwenkrahmens mit dem Kopf der Stange der Federanordnung in Berührung und verschiebt die Stange unter axialer Kompression der Schraubendruckfeder. Diese Ausführung ist deswegen vorteilhaft, weil sie nur eine geringe Einbaulänge benötigt. Der dafür erforderlich Raum ist zwischen den auf gleichem Niveau liegenden Lagern der beiden Schwenkrahmen jeder Führungseinrichtung immer vorhanden, auch dann, wenn die Schwenkrahmen sehr steil stehen.The spring arrangement can, for example, be designed as a leaf or leg spring and be mounted in the joint area of the two swivel frames in such a way that the spring tensions between the two frames when the angle is reduced. It is also within the scope of the invention to use a tension spring, for example in the form of a strong rubber band, which is attached to the leg of a swivel frame associated with the sliding bearings and is attached with its other end to a fixed point on the lifting plate or the base frame, that the sliding bearings from their fixed bearings be pulled away. A particularly preferred embodiment of the invention is that the spring arrangement has a straight rod, on which a helical compression spring is arranged, which presses at one end against a head of the rod, which forms a stop for the sliding bearing region of the pivot frame and that the other end of the Rod is axially displaceably guided in a bore or a channel of a fastening fitting, which has a front surface and a rear surface and the bore or the channel extends between the front and rear surfaces and that the other end of the helical compression spring is supported on the front surface and one on other end of the rod provided foot engages behind the rear surface of the mounting bracket. The helical compression spring is preferably pretensioned, so that the foot of the rod is also supported on the rear surface of the fastening fitting. This mounting bracket is preferably housed within a rail that also carries a sliding bearing of a swivel frame. The sliding bearing or a driver moved by it thus comes into contact with the head of the rod of the spring arrangement during the last pivoting phase of the pivoting frame and displaces the rod with axial compression of the helical compression spring. This version is advantageous because it only requires a small installation length. The space required for this is always available between the bearings of the two swivel frames of each guide device, which are on the same level, even if the swivel frames are very steep.

Anhand der Zeichnung, die einige Ausführungsbeispiele darstellt, sei die Erfindung näher beschrieben.The invention will be described in more detail with reference to the drawing, which shows some exemplary embodiments.

Ein Badewanneneinsatz 10 besteht aus einem Bodengestell 12, einer Hubplatte 14, zwei Führungseinrichtungen 16 in Form von je zwei gelenkig miteinander verbundenen Schwenkrahmen 18, 20, die mittels Lenkerstangen 22 für eine gemeinsame Bewegung synchronisiert sind, sowie zwei Druckwasserschläuchen 24, deren Enden am Bodengestell 12 und an der Hubplatte 14 befestigt sind.A bathtub insert 10 consists of a floor frame 12, a lifting plate 14, two guide devices 16 in the form of two articulated swivel frames 18, 20, which are synchronized by means of handlebars 22 for joint movement, and two pressurized water hoses 24, the ends of which are on the floor frame 12 and are attached to the lifting plate 14.

Beide Schwenkrahmen 18, 20 sind Rechteckrahmen, die im Mittelbereich durch eine Gelenkstange miteinander gelenkig verbunden sind. Der Schwenkrahmen 20 ist schmaler als der Schwenkrahmen 18, sodaß er in der abgesenkten Stellung der Hubplatte 14 in diesen hineinpaßt. Der äußere Schwenkrahmen 18 hat zwei obere Festlager 26 und zwei untere Schiebelager 28, die in Schienen 30 am Bodengestell 12 geführt sind. Der innere Schwenkrahmen 20 hat zwei untere Festlager 32 und zwei obere Schiebelager 34, die in entsprechenden Schienen an der Unterseite der Hubplatte 14 geführt sind.Both swivel frames 18, 20 are rectangular frames which are articulated to one another in the central region by an articulated rod. The swivel frame 20 is narrower than the swivel frame 18 so that it fits into the lifting plate 14 in the lowered position thereof. The outer pivot frame 18 has two upper fixed bearings 26 and two lower sliding bearings 28 which are guided in rails 30 on the base frame 12. The inner swivel frame 20 has two lower fixed bearings 32 and two upper sliding bearings 34 which are guided in corresponding rails on the underside of the lifting plate 14.

Am oberen Querholm zwischen beiden Schiebelagern 34 des inneren Schwenkrahmens 20 ist eine Federanordnung 36 in Form eines starken Gummiseiles angebracht, dessen anderes Ende zum benachbarten oberen Querholm zwischen den Festlagern 26 des äußeren Schwenkrahmens 18 der anderen Führungseinrichtung 16 führt. Dieses Ende des Gummiseiles kann ebensogut an der Unterseite der Hubplatte 14 unmittelbar befestigt werden.On the upper cross member between the two sliding bearings 34 of the inner pivot frame 20, a spring arrangement 36 is attached in the form of a strong rubber rope, the other end of which leads to the adjacent upper cross member between the fixed bearings 26 of the outer pivot frame 18 of the other guide device 16. This end of the rubber cord can also be attached directly to the underside of the lifting plate 14.

Fährt nun die Hubplatte 14 in die in FIG. 2 dargestellte Hochstellung, so wird die Federanordnung 36 zunehmend gespannt. Die Schwenkrahmen 18, 20 jeder Führungseinrichtung 16 können sehr steil gestellt werden, ohne daß beim anschließenden Entlasten der Druckwasserschläuche 24 die Schiebelager 34 in den Schienen 30 verklemmen, da die Federanordnung 36 ein solches Verklemmen verhindert oder überwindet.Now moves the lifting plate 14 in the in FIG. 2 high position shown, the spring assembly 36 is increasingly tensioned. The swivel frames 18, 20 of each guide device 16 can be set very steeply without the sliding bearings 34 jamming in the rails 30 when the pressure water hoses 24 are subsequently relieved, since the spring arrangement 36 prevents or overcomes such jamming.

Die Figuren 3 und 4 veranschaulichen eine abgewandelte Ausführungsform einer Federanordnung 36, die einen Befestigungsbeschlag 38 aufweist, dessen Querschnitt etwa dem lichten Querschnitt der Schiene 30 an der Bodenseite der Hubplatte 14 entspricht und der sich über eine gewisse Länge innerhalb dieser Schiene 30 erstreckt. Durch die ganze Länge des Befestigungsbeschlages 38 hindurch erstreckt sich eine gerade Stange 40, die eine im hinteren Teil des Befestigungsbeschlages 38 vorgesehene Bohrung 42 mit Schiebespiel durchsetzt. Die Bohrung 42 erstreckt sich durch eine Querwand des Befestigungsbeschlages 38, an die sich nach vorn ein oben offener kanalartiger Durchbruch 44 anschließt, der einen etwas größeren Querschnitt als die Bohrung 42 hat. Auf der Stange 40 ist eine zylindrische Schraubendruckfeder 46 längsverschiebbar geführt, deren eines Ende sich an einer auf die Stange 40 aufgeschraubten Mutter abstützt, die für die Stange 40 einen Kopf 48 bildet. Das andere Ende der Schraubendruckfeder 46 liegt an der Vorderfläche der die Bohrung 42 aufweisenden Querwand an. Die Schraubendruckfeder 46 ist mit Vorspannung eingebaut, sodaß sich eine auf das hintere Ende der Stange 40 aufgeschraubte Mutter an der Hinterfläche dieser Querwand abstützt. Diese Mutter bildet einen Fuß 50 der Stange 40. Der Befestigungsbeschlag 38 ist in Form eines Kunststoffkörpers ausgebildet, der mittels zweier Schrauben 52 an einer Seitenwand der Schiene 30 festgeschraubt ist.FIGS. 3 and 4 illustrate a modified embodiment of a spring arrangement 36 which has a fastening fitting 38, the cross section of which corresponds approximately to the clear cross section of the rail 30 on the bottom side of the lifting plate 14 and which extends over a certain length within this rail 30. A straight rod 40 extends through the entire length of the fastening fitting 38 and passes through a bore 42 provided in the rear part of the fastening fitting 38 with sliding play. The bore 42 extends through a transverse wall of the fastening fitting 38, which is adjoined at the front by a channel-like opening 44 which is open at the top and which has a somewhat larger cross section than the bore 42. A cylindrical helical compression spring 46 is guided in a longitudinally displaceable manner on the rod 40, one end of which is supported on a nut screwed onto the rod 40, which forms a head 48 for the rod 40. The other end of the helical compression spring 46 rests on the front surface of the transverse wall having the bore 42. The helical compression spring 46 is installed with pretension so that a nut screwed onto the rear end of the rod 40 is supported on the rear surface of this transverse wall. This nut forms a foot 50 of the rod 40. The mounting bracket 38 is in the form of a plastic body which is screwed onto a side wall of the rail 30 by means of two screws 52.

Gemäß FIG. 3 schwenkt der innere Schwenkrahmen 20 jeder der beiden Führungseinrichtungen 16 im Uhrzeigergegedrehsinn nach oben und die beiden Schiebelager 34 in Form von in den Schienen 30 laufenden Gleitstücken kommen je mit dem Kopf 48 der verschiebbaren Stange 40 in Berührung. Beim Weiterschwenken des Schwenkrahmens 20 wird die Stange 40 nach links verschoben und die Druckfeder 46 komprimiert. Je steiler die Schwenkrahmen 18, 20 gestellt werden, umso stärker wird die gespeicherte Kraft der Druckfeder 46. Die Kraft der Feder 46 ist so bemessen, daß die durch Steilstellung der Schwenkrahmen 18, 20 entstehende Klemmneigung der Schiebelager 34 in den Schienen 30 überwunden wird.According to FIG. 3, the inner swivel frame 20 pivots each of the two guide devices 16 in a clockwise direction upwards and the two sliding bearings 34 in the form of sliding pieces running in the rails 30 come into contact with the head 48 of the displaceable rod 40. When pivoting the pivot frame 20, the rod 40 is shifted to the left and the compression spring 46 is compressed. The steeper the swivel frames 18, 20 are set, the stronger the stored force of the compression spring 46. The force of the spring 46 is dimensioned such that the tendency of the sliding bearings 34 in the rails 30 to clamp due to the steep position of the swivel frames 18, 20 is overcome.

In der Praxis hat es sich als ausreichend erwiesen, einen nutzbaren Federweg für die Federanordnung 36 von etwa 60 mm bis etwa 80 mm vorzusehen. Die gesamte Federanordnung 36 hat dann etwa die doppelte Länge. Dank der maßgeblichen Länge des Befestigungsbeschlages 38 innerhalb der Schiene 30 ist die Druckfeder 46 zwangsgeführt und zwar dadurch, daß sie durch die innenverlaufende Stange 40 stabilisiert ist, die am hinteren Ende eine Schiebeführung in der Bohrung 42 aufweist, während der kanalartige Durchbruch 44 die Schraubenfeder 46 bis zum vorderen Ende des Befestigungsbeschlages 38 hin unmittelbar führt.In practice, it has proven sufficient to provide a usable spring travel for the spring arrangement 36 of approximately 60 mm to approximately 80 mm. The entire spring arrangement 36 then has approximately twice the length. Thanks to the significant length of the mounting bracket 38 within the rail 30, the compression spring 46 is positively guided, namely in that it is stabilized by the inner rod 40, which has a sliding guide in the bore 42 at the rear end, while the channel-like opening 44, the coil spring 46 leads directly to the front end of the mounting bracket 38.

Claims (10)
