Die Erfindung betrifft einen Dusch- und Toilettenstuhl mit einem höhenverstellbaren Sitz und einer Hubeinrichtung.The invention relates to a shower and toilet chair with a height-adjustable seat and a lifting device.
Ein Dusch- und Toilettenstuhl der in Rede stehenden Art ist beispielsweise aus der
Stühle der in Rede stehenden Art verfügen über eine Hubeinrichtung, mittels derer der Sitz angehoben und abgesenkt werden kann. Eine derartige Hubeinrichtung verfügt über eine Antriebsvorrichtung und über ein System aus Hebeln und Gelenken, das dazu dient, die Bewegung der Antriebsvorrichtung in eine Hub- oder Absenkbewegung des Sitzes umzuwandeln.Chairs of the type in question have a lifting device by means of which the seat can be raised and lowered. Such a lifting device has a drive device and a system of levers and joints, which serves to convert the movement of the drive device in a lifting or lowering movement of the seat.
Der Erfindung liegt die Aufgabe zugrunde, einen Dusch- und Toilettenstuhl der vorstehend genannten Art bereitzustellen, bei dem diese Hubeinrichtung vorteilhaft ausgeführt ist, insbesondere hinsichtlich Fertigung als auch hinsichtlich Funktion und Funktionalität.The invention has for its object to provide a shower and toilet chair of the aforementioned type, in which this lifting device is designed advantageously, in particular in terms of manufacturing as well as in terms of function and functionality.
Die Lösung dieser Aufgabe ist in Patentanspruch 1 angegeben. Vorteilhafte Ausführungsformen sind in den Unteransprüchen definiert.The solution of this problem is specified in claim 1. Advantageous embodiments are defined in the subclaims.
Der erfindungsgemäße Dusch- und Toilettenstuhl weist einen höhenverstellbaren Sitz und eine Hubeinrichtung auf, die zum Anheben und Absenken des Sitzes dient. Die Hubeinrichtung verfügt über eine Tragstrebe, die mit dem Sitz verbunden ist. Weiterhin verfügt die Hubeinrichtung über eine erste Strebe, die mit der Tragstrebe gelenkig verbunden ist, wodurch eine erste Schwenkachse definiert wird. Die erste Strebe ist zudem mit einem festen Strebenelement gelenkig verbunden, wodurch eine zweite Schwenkachse definiert wird. Des Weiteren verfügt die Hubeinrichtung über eine Antriebsvorrichtung, die schwenkbar an dem festen Strebenelement angeordnet ist, sowie ein von der Antriebsvorrichtung bewegbares Antriebselement, das mit der Tragstrebe gelenkig verbunden ist, wodurch eine dritte Schwenkachse definiert wird, die von der ersten Schwenkachse beabstandet ist. Die Anlenkung der Antriebsvorrichtung an dem festen Strebenelement ist so ausgeführt, dass die Antriebsvorrichtung um die zweite Schwenkachse verschwenkbar ist.The shower and toilet chair according to the invention has a height-adjustable seat and a lifting device which serves to raise and lower the seat. The lifting device has a support strut, which is connected to the seat. Furthermore, the lifting device has a first strut, which is pivotally connected to the support strut, whereby a first pivot axis is defined. The first strut is also hingedly connected to a fixed strut member defining a second pivot axis. Furthermore, the lifting device has a drive device, which is arranged pivotably on the fixed strut element, and a drive device movable by the drive element, which is pivotally connected to the support strut, whereby a third pivot axis is defined, which is spaced from the first pivot axis. The articulation of the drive device to the fixed strut element is designed so that the drive device is pivotable about the second pivot axis.
Die koaxiale Lagerung der verschwenkbaren Antriebsvorrichtung mit der ersten Strebe führt dazu, dass ein gemeinsames Lagerelement verwendet werden kann, d.h. ein multifunktionelles Bauteil, welches beide Funktionen, nämlich die Lagerung der ersten Strebe und der Antriebsvorrichtung übernimmt. Hierdurch ergibt sich eine Materialersparnis, die zur Senkung von Kosten führt und zudem durch die Einsparung von Ressourcen umweltfreundlich ist. Des Weiteren wird die Zahl der Montageschritte reduziert und eine entsprechende Zeitersparnis bei der Montage ermöglicht. Eine weitere Kostensenkung wird durch die Einsparung an Schraubensicherungslack und sonstiger Hilfsmittel ermöglicht. Schließlich werden in den entsprechenden Bauteilen die Spannungen reduziert, da die Kräfte in eine gemeinsame Drehachse eingeleitet werden.The coaxial mounting of the pivotable drive device with the first strut results in a common bearing element being used, i. a multifunctional component, which performs both functions, namely the storage of the first strut and the drive device. This results in a material savings, which leads to the reduction of costs and also by the conservation of resources is environmentally friendly. Furthermore, the number of assembly steps is reduced and allows a corresponding time savings during assembly. A further cost reduction is made possible by the savings on threadlocker and other aids. Finally, the stresses are reduced in the corresponding components, since the forces are introduced into a common axis of rotation.
Die Hubeinrichtung kann zudem eine weitere Strebe aufweisen, die gelenkig an dem festen Strebenelement und an der Tragstrebe angeordnet ist, wobei die Anlenkung der zweiten Strebe an der Tragstrebe so ausgeführt sein kann, dass die zweite Strebe um die dritte Schwenkachse schwenkbar ist, und die Anlenkung der zweiten Strebe an dem festen Strebenelement so ausgeführt sein kann, dass eine vierte Schwenkachse definiert wird, die von der zweiten Schwenkachse beabstandet ist. Mit dieser vorteilhaften Ausführungsform wird eine Parallelogrammstruktur verwirklicht, die bei entsprechender Ausführung eine für den vorliegenden Anmeldungsfall besonders geeignete Hubbewegung verwirklichen kann.The lifting device may also comprise a further strut which is articulated to the fixed strut element and the support strut, wherein the articulation of the second strut on the support strut may be designed so that the second strut is pivotable about the third pivot axis, and the articulation the second strut on the fixed strut element may be configured such that a fourth pivot axis is defined, which is spaced from the second pivot axis. With this advantageous embodiment, a parallelogram structure is realized which, with a corresponding design, can realize a lifting movement which is particularly suitable for the present application.
Vorzugsweise sind zwei derartige Hubeinrichtungen vorgesehen und parallel zueinander angeordnet. Es können demnach zwei Antriebsvorrichtungen und zwei Hebelstrukturen, insbesondere Parallelogrammstrukturen verwirklicht werden, die auf je einer Seite des Dusch- und Toilettenstuhls angeordnet sind und gemeinsam den Sitz tragen sowie heben und absenken.Preferably, two such lifting devices are provided and arranged parallel to each other. It can therefore be realized two drive devices and two lever structures, in particular parallelogram, which are arranged on each side of the shower and toilet chair and together wear the seat and raise and lower.
Die zweite Schwenkachse, d.h. diejenige Schwenkachse, welche sowohl Schwenkachse für die erste Strebe als auch Schwenkachse für die Antriebsvorrichtung ist, kann vorzugsweise durch einen Lagerbolzen gebildet sein. Auf dem Lagerbolzen kann ein erster Lagersitz zur Lagerung der ersten Strebe und ein zweiter Lagersitz zur Lagerung der Antriebsvorrichtung ausgebildet sein, wobei zwischen dem ersten Lagersitz und dem zweiten Lagersitz ein Sechskant und am Ende des Lagerbolzens ein Gewindezapfen ausgebildet sein kann, mit dem der Lagerbolzen in dem festen Strebenelement verschraubt werden kann. Der Sechskant, der funktional und räumlich den ersten Lagersitz von dem zweiten Lagersitz trennt, kann zum Ansetzen eines Schraubenschlüssels beim Einschrauben des Lagerbolzens in das feste Strebenelement dienen.The second pivot axis, i. that pivot axis, which is both pivot axis for the first strut and pivot axis for the drive device, may preferably be formed by a bearing pin. On the bearing pin, a first bearing seat for supporting the first strut and a second bearing seat for supporting the drive device may be formed, wherein between the first bearing seat and the second bearing seat a hexagon and at the end of the bearing bolt a threaded pin may be formed with which the bearing pin in can be screwed to the solid strut element. The hexagon, which separates functionally and spatially the first bearing seat from the second bearing seat, can be used to attach a wrench when screwing the bearing bolt in the fixed strut element.
Es versteht sich, dass anstelle eines Außengewindes am Ende des Lagerbolzens auch eine Bohrung mit Innengewinde vorgesehen sein kann, so dass der Lagerbolzen über einen entsprechenden Gewindestift geschraubt werden kann, der an dem festen Strebenelement vorgesehen ist.It is understood that instead of an external thread at the end of the bearing pin and a bore with internal thread can be provided so that the bearing pin can be screwed via a corresponding threaded pin, which is provided on the fixed strut element.
Der Lagerbolzen kann aus Vollmaterial gefertigt sein. Abhängig von der Wahl des Materials und der Dimensionierung der jeweiligen Bauteile kann der Lagerbolzen auch innen hohl oder mit entsprechend abgesetzten Innendurchmessern ausgeführt sein.The bearing pin can be made of solid material. Depending on the choice of material and dimensioning the respective components of the bearing pin can also be made hollow inside or with corresponding remote inner diameters.
Die Durchmesser der beiden Lagersitze können abhängig von den gewählten Hebelverhältnissen und hieraus resultierenden Kräften gleich groß oder auch unterschiedlich groß sein, sowohl in der axialen Länge der Lagersitze als auch hinsichtlich der Durchmesser.The diameters of the two bearing seats can be the same size or different sizes, depending on the selected lever ratios and resulting forces, both in the axial length of the bearing seats and in terms of diameter.
Als Antriebsvorrichtung kann sowohl ein Elektromotor verwendet werden, wobei bei der parallelen Anordnung von zwei Hubeinrichtungen zwei Elektromotoren verwendet werden können, als auch hydraulische, pneumatische oder manuell zu bedienende mechanische Antriebseinheiten.As the drive device, both an electric motor can be used, wherein in the parallel arrangement of two lifting devices two electric motors can be used, as well as hydraulic, pneumatic or manually operated mechanical drive units.
Der erfindungsgemäße Dusch- und Toilettenstuhl kann zudem über eine Neigevorrichtung verfügen, die ein Neigen des Sitzes bewirkt. Zudem kann der Stuhl mit vier Lenkrollen ausgerüstet sein, d.h. Rädern, welche eine oder mehrere frei drehbare Rollen aufweisen, die an Trägern montiert sind, welche vertikale Rotationsachsen aufweisen, wobei die horizontalen Drehachsen der Rollen von den vertikalen Rotationsachsen der Träger beabstandet sind, d.h. einen so genannten Nachlauf aufweisen.The shower and toilet chair according to the invention may also have a tilting device, which causes a tilting of the seat. In addition, the chair can be equipped with four castors, i. Wheels having one or more freely rotatable rollers mounted on supports having vertical axes of rotation, the horizontal axes of rotation of the rollers being spaced from the vertical axes of rotation of the supports, i. have a so-called caster.

Fig. 3 eine Seitenansicht der Ausführungsform gemäßFig. 1 in einer Stellung zeigt, in der der Sitz abgesenkt ist, -
Fig. 4 eineFig. 3 entsprechende Darstellung ist, in der der Sitz angehoben ist, und -
Fig. 5 eine Ausführungsform eines Lagerbolzens zeigt.
In den Figuren dargestellt ist ein elektrisch betriebener Dusch- und Toilettenstuhl mit einemSitz 101, der eineRückenlehne 102, eineKopfstütze 103,Armlehnen 104 undFußstützen 105 aufweist. Auf einem Fahrgestell ist eine Hubmechanik angeordnet, mittels derer derSitz 101 in der Höhe verstellt werden kann.Fig. 3 zeigt denSitz 101 in einer abgesenkten Stellung undFig. 4 zeigt denSitz 101 in einer angehobenen Stellung.
An den vier äußeren Punkten des Fahrgestells sindLenkrollen 109 angeordnet.
Die Hubmechanik weist zwei parallel zueinander angeordnete Hubeinrichtungen auf, von denen jeweils eine auf einer Seite des Dusch- und Toilettenstuhls angeordnet ist. DerSitz 101 ist auf jeder seiner beiden Seiten jeweils mit einemHalteelement 145 verbunden, welches Bestandteil der Hubeinrichtung ist. Hierdurch ergibt sich auf jeder Seite desSitzes 101 einBefestigungspunkt 107. Jeweils einweiterer Befestigungspunkt 108 ergibt sich durch Verbindung mit zwei Elementen einerNeigeeinrichtung 180, die dazu ausgelegt ist, denSitz 101 in seiner Neigung zu verstellen.
Im Folgenden wird die auf der linken Seite des Dusch- und Toilettenstuhls angeordnete Hubeinrichtung beschrieben. Es versteht sich, dass eine entsprechende Hubeinrichtung parallel hierzu auf der rechten Seite des Dusch- und Toilettenstuhls vorgesehen ist. Entsprechend sind auf der linken Seite eine Antriebsvorrichtung in Form einesElektromotors 150L und auf der rechten Seite einentsprechender Elektromotor 150R vorgesehen. Derlinke Elektromotor 150L und derrechte Elektromotor 150R können identisch und lediglich seitenverkehrt zueinander auf den jeweiligen Seiten verbaut sein.
Einfestes Strebenelement 141 ist ortsfest, d. h. nicht schwenkbar mit dem Fahrgestell des Dusch- und Toilettenstuhls verbunden. An demfesten Strebenelement 141 sind schwenkbar eineerste Strebe 142 und einezweite Strebe 143 angeordnet. Dieerste Strebe 142 und diezweite Strebe 143 sind schwenkbar mit einerTragstrebe 144 verbunden, an der dasHalteelement 145 befestigt ist. Der Schwenkpunkt derersten Strebe 142 mit derTragstrebe 144 definiert eineerste Schwenkachse 146. Der Schwenkpunkt derersten Strebe 142 mit demfesten Strebenelement 141 definiert einezweite Schwenkachse 147. Der Schwenkpunkt derzweiten Strebe 143 mit derTragstrebe 144 definiert einedritte Schwenkachse 148 und der Schwenkpunkt derzweiten Strebe 143 mit demfesten Strebenelement 141 definiert einevierte Schwenkachse 149. Alle vier 146, 147, 148 und 149 sind voneinander beabstandet und dasSchwenkachsen feste Strebenelement 141, dieerste Strebe 142, diezweite Strebe 143 und dieTragstrebe 144 bilden eine Parallelogrammstruktur.
DerElektromotor 150L ist verschwenkbar an demfesten Strebenelement 144 angelenkt, wobei die Schwenkachse desElektromotors 150 L um dasfeste Strebenelement 141 diezweite Schwenkachse 147 ist. Mit demElektromotor 150L verbunden ist einAntriebselement 151. Je nach Drehrichtung desElektromotors 150L wird dasAntriebselement 151 eingefahren, d.h. in Richtung auf denElektromotor 150L hin bewegt, oder ausgefahren, d.h. in Richtung von demElektromotor 150L weg bewegt.Das dem Elektromotor 150L gegenüberliegende Ende desAntriebselements 151 ist gelenkigmit der Tragstrebe 144 verbunden, wobei der Schwenkpunkt derTragstrebe 144 gegenüberdem Antriebselement 151die dritte Schwenkachse 148 ist.
Wenn der Elektromotor 150L und der ihm entsprechendeElektromotor 150R auf der rechten Seite des Dusch- und Toilettenstuhls (inFig. 3 nicht gezeigt) so betrieben werden, dass diejeweiligen Antriebselemente 151 ausgefahren werden, wird derSitz 101 angehoben. BeiEinfahren des Antriebselements 151 zu 150L, 150R hin wird derdem jeweiligen Elektromotor Sitz 101 abgesenkt. Aus dem Vergleich der Darstellungen gemäß denFiguren 3 und4 ergibt sich, dass hierbei derElektromotor 150L und selbstverständlich auch der auf der anderen Seite angeordneteElektromotor 150R eine Schwenkbewegung um diezweite Schwenkachse 147 ausführen.Die erste Strebe 142 führt ebenfalls eine Schwenkbewegung um diezweite Schwenkachse 147 aus.
Im Folgenden wird anhand vonFig. 5 die Ausführungsform eines Lagerbolzens erläutert, dessen Mittellinie auf der zweiten Schwenkachse 147 liegt und der somit die erläuterten Schwenkbewegungen ermöglicht. In Verbindung mitFig. 5 istFig. 2 zu sehen, die in einer vergrößerten Detaildarstellung die Anordnung weiterer Bauteile aufdem Lagerbolzen 170 zeigt.
Der Lagerbolzen 170 verfügt über einenGewindezapfen 174, überden der Lagerbolzen 170 mitdem festen Strebenelement 141 verschraubt ist.Zwischen dem Gewindezapfen 174 und einem aufdem Lagerbolzen 170ausgebildeten Sechskant 173ist ein Lagersitz 171 zur Lagerung der erstenStrebe 142 ausgebildet. Auf der gegenüberliegenden Seite desSechskants 173ist ein Lagersitz 172 zur Aufnahme desElektromotors 150L ausgebildet. Es versteht sich, dass die Befestigung desLagerbolzens 170 andem festen Strebenelement 141 auch durch andere geeignete Ausführungsformen bewirkt werden kann, beispielsweise durch Verwendung eines Innenmehrkants, einer Bohrung oder eines Schlitzes oder dergleichen. Es versteht sich zudem, dass die Dimensionierung der Lagersitze in Abhängigkeit der einzuleitenden Kräfte erfolgt und von der dargestellten Ausführungsform abweichen kann.

Fig. 1 shows a perspective view of an embodiment of the shower and toilet chair according to the invention, -
Fig. 2 an enlarged perspective view of the detail Z according toFig. 1 shows, -
Fig. 3 a side view of the embodiment according toFig. 1 in a position in which the seat is lowered, -
Fig. 4 aFig. 3 corresponding representation is in which the seat is raised, and -
Fig. 5 shows an embodiment of a bearing pin.
Shown in the figures is an electrically operated shower and toilet chair with aseat 101 having abackrest 102, aheadrest 103,armrests 104 andfootrests 105. On a chassis a lifting mechanism is arranged, by means of which theseat 101 can be adjusted in height.Fig. 3 shows theseat 101 in a lowered position andFig. 4 shows theseat 101 in a raised position.
At the four outer points of thechassis castors 109 are arranged.
The lifting mechanism has two mutually parallel lifting devices, one of which is arranged on each side of the shower and toilet chair. Theseat 101 is connected on each of its two sides in each case with a holdingelement 145 which is part of the lifting device. This results in anattachment point 107 on each side of theseat 101. In each case afurther attachment point 108 results from connection to two elements of atilting device 180, which is designed to adjust theseat 101 in its inclination.
In the following, the lifting device arranged on the left side of the shower and toilet chair will be described. It is understood that a corresponding lifting device is provided parallel to this on the right side of the shower and toilet chair. Accordingly, a driving device in the form of anelectric motor 150L is provided on the left side, and a correspondingelectric motor 150R is provided on the right side. The leftelectric motor 150L and the rightelectric motor 150R may be identical and installed only side-inverted to each other on the respective sides.
Asolid strut element 141 is stationary, ie not pivotally connected to the chassis of the shower and toilet chair. On the fixedstrut element 141, afirst strut 142 and asecond strut 143 are pivotally arranged. Thefirst strut 142 and thesecond strut 143 are pivotally connected to asupport strut 144 to which thesupport member 145 is attached. The pivot point of thefirst strut 142 with thesupport strut 144 defines afirst pivot axis 146. The pivot point of thefirst strut 142 with the fixedstrut element 141 defines asecond pivot axis 147. The pivot point of thesecond strut 143 with thesupport strut 144 defines athird pivot axis 148 and Pivot point of thesecond strut 143 with the fixedstrut element 141 defines afourth pivot axis 149. All four 146, 147, 148 and 149 are spaced apart and thepivot axes strut 141, thefirst strut 142, thesecond strut 143 and thesupport strut 144 form a parallelogram.
Theelectric motor 150L is pivotably coupled to the fixedstrut element 144, wherein the pivot axis of theelectric motor 150 L about the fixedstrut element 141 is thesecond pivot axis 147. Connected to theelectric motor 150L is adrive member 151. Depending on the direction of rotation of theelectric motor 150L, thedrive member 151 is retracted, ie, moved toward theelectric motor 150L, or extended, ie, moved in the direction away from theelectric motor 150L. Theelectric motor 150L opposite end of thedrive member 151 is pivotally connected to thesupport strut 144, wherein the pivot point of thesupport strut 144 relative to thedrive member 151 is thethird pivot axis 148.
When theelectric motor 150L and its correspondingelectric motor 150R on the right side of the shower and toilet chair (in FIGFig. 3 not shown) are operated so that therespective drive elements 151 are extended, theseat 101 is raised. When retracting theDrive member 151 to the respective 150L, 150R down theelectric motor seat 101 is lowered. From the comparison of the representations according toFigures 3 and4 shows that in this case theelectric motor 150L and, of course, also theelectric motor 150R arranged on the other side perform a pivotal movement about thesecond pivot axis 147. Thefirst strut 142 also performs a pivotal movement about thesecond pivot axis 147.
The following is based onFig. 5 explains the embodiment of a bearing pin whose center line is located on thesecond pivot axis 147 and thus allows the described pivoting movements. Combined withFig. 5 isFig. 2 to see the arrangement of other components on thebearing pin 170 in an enlarged detail.
Thebearing pin 170 has a threadedpin 174, via which thebearing pin 170 is screwed to the fixedstrut element 141. Between the threadedpin 174 and ahexagon 173 formed on thebearing pin 170, abearing seat 171 for mounting thefirst brace 142 is formed. On the opposite side of thehexagon 173, abearing seat 172 for receiving theelectric motor 150L is formed. It is understood that the attachment of thebearing pin 170 to the fixedstrut element 141 can also be effected by other suitable embodiments, for example by using an internal polygon, a bore or a slot or the like. It is also understood that the dimensioning of the bearing seats takes place as a function of the forces to be introduced and can deviate from the illustrated embodiment.
