Die vorliegende Erfindung betrifft eine Sitzvorrichtung nach dem Oberbegriff des Patentanspruchs 1.The present invention relates to a seat device according to the preamble of the claim 1.

Bei bettlägerigen und pflegebedürftigen Personen in Spitälern, Pflegeheimen etc. ist es für verschiedene Verrichtungen im Rahmen der Betreuung und Pflege oft zweckmässig, die Person vorübergehend von einer liegenden in eine sitzende Stellung zu bringen. In vielen Fällen muss die Person die Füsse auf den Boden setzen können, ohne das Bett ganz verlassen zu müssen. Dabei besteht insbesondere das Problem, die Vorrichtung bezüglich ihrer Lage jederzeit zu stabilisieren und ein Verschieben auf dem Bett mit Sicherheit zu verhindern. Aus der US-PS 3 343 185 ist eine Sitzvorrichtung mit Rückenlehne bekannt, die quer zur Längsrichtung auf der Matratze eines Bettes angeordnet wird und mit der der Patient seitlich auf dem Bett eine sitzende Position einnehmen kann. Die Stabilisierung dieser Vorrichtung wird durch Festklemmen an der Matratze und durch zusätzlich an den Armlehnen angebrachte Hilfsmittel erreicht, die auf die Matratze drücken, wenn sich die Person auf die Armlehnen stützt. Diese Vorrichtung ist aufwendig und entsprechend teuer, weil sie aus vielen zusammengesetzten Teilen besteht.It is different for bedridden and people in need of care in hospitals, nursing homes etc. Performances in the context of care and maintenance are often appropriate, the person to temporarily move from a lying to a sitting position. In many cases the person can put their feet on the floor without having to leave the bed entirely. In particular, there is the problem of stabilizing the device's position at any time and certainly prevent moving on the bed. From U.S. Patent 3,343 185 is known a seat device with backrest, which is transverse to the longitudinal direction on the mattress a bed is arranged and with which the patient is sitting on the side of the bed Can take position. The stabilization of this device is done by clamping on the Mattress and achieved by means of additional devices attached to the armrests, which on the Press the mattress when the person rests on the armrests. This device is complex and accordingly expensive because it consists of many assembled parts.

Ferner ist aus der AU 0 558 658 eine Sitzvorrichtung mit einer Rückenlehne und einem einstükkigen Klemmteil bekannt, der über die Matratze geschoben wird. Die Rückenlehne ist an einem Gestell angebracht, das über weitere Befestigungsmittel mit dem Klemmteil verbunden ist. Auch bei dieser Vorrichtung ist der Herstellungsaufwand relativ gross.Furthermore, from AU 0 558 658 is a seat device with a backrest and one piece Known clamping part that is pushed over the mattress. The backrest is on one Mounted attached, which is connected to the clamping part via further fastening means. Also In this device, the manufacturing effort is relatively large.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art anzugeben, die aus wenigen Teilen aufgebaut ist und die sich dementsprechend kostengünstig herstellen lässt.The present invention is therefore based on the object of a device at the outset Specify the type mentioned, which is made up of a few parts and which is accordingly can be produced inexpensively.

In Fig. 1 ist der prinzipielle Aufbau der Sitzvorrichtung gezeigt. Sie besteht aus einem Träger 1, der zwei wenigstens annähernd zueinander parallele L-förmige Teile 2, 3 mit je zwei Abschnitten 2a, 2b bzw. 3a, 3b und einen U-förmigen Teil mit zwei Schenkeln 4a, 4b aufweist. Als Träger 1 eignet sich insbesondere ein Rohr aus Edelstahl, das entsprechend geformt ist. Die beiden Abschnitte 2b, 3b der L-förmigen Teile 2, 3 sind an einem ihrer Enden so mit je einem Schenkel des U-förmigen Teils 4 verbunden, dass sie wenigstens annähernd parallel zum U-förmigen Teil 4 verlaufen und zu diesem einen Abstand aufweisen, der es erlaubt, dazwischen eine Sitzauflage, z.B. die Matratze 6 eines Bettes (Fig.2), aufzunehmen. Die beiden anderen Abschnitte 2a, 3a der L-förmigen Teile 2, 3 sind durch eine Ruckenlehne 5 miteinander verbunden, die ein-oder mehrteilig sein kann. Die Rückenlehne 5 wird in bekannter Weise zwischen oder auf den Abschnitten 2a und 3a befestigt.1 shows the basic structure of the seat device. It consists of a carrier 1, of the two at least approximately parallel L-shaped parts 2, 3, each with two sections 2a, 2b or 3a, 3b and a U-shaped part with two legs 4a, 4b. As carrier 1 a tube made of stainless steel, which is shaped accordingly, is particularly suitable. The two sections 2b, 3b of the L-shaped parts 2, 3 are at one of their ends with one leg each of the U-shaped part 4 connected that they are at least approximately parallel to the U-shaped part 4 run and have a distance from it that allows a seat pad between them, e.g. the mattress 6 of a bed (Fig.2). The other two sections 2a, 3a of the L-shaped parts 2, 3 are connected to one another by a backrest 5, which is in or out can be in several parts. The backrest 5 is in a known manner between or on the Sections 2a and 3a attached.

Fig. 2 zeigt die Sitzvorrichtung bei Anwendung in einem Bett. Fig. 2a zeigt eine Seitenansicht, d.h. eine Sicht vom fussseitigen Bettende auf die Sitzvorrichtung und Fig. 2b eine Vorderansicht. Die Vorrichtung wird seitlich so über die Matratze 6 geschoben, dass der U-förmige Teil unter die Matratze 6 auf das Bettgestell bzw. auf die Matratzenauflage 10 und die beiden Abschnitte 2b und 3b der L-förmigen Teile 2, 3 unmittelbar über der Matratze 6 zu liegen kommen. Der Abstand zwischen den Abschnitten 2b, 3b und dem U-förmigen Teil 4 entspricht in etwa der Dicke der Matratze 6. Wie aus Fig. 2a ersichtlich, sind die beiden Schenkel 4a, 4b des U-förmigen Teils 4 ungefähr so lang wie die Breite der Matratze 6, was die beste Stabilität für die Sitzvorrichtung und damit für die sitzende Person ergibt. Die Länge der beiden Abschnitte 2b, 3b ist so gewählt, dass der Abstand der Rückenlehne 5 zum Bettrand eine genügend grosse Sitzfläche für die sitzende Person ergibt.Fig. 2 shows the seat device when used in a bed. 2a shows a side view, i.e. a view from the foot end of the bed on the seat device and Fig. 2b is a front view. The device is pushed laterally over the mattress 6 so that the U-shaped Part under the mattress 6 on the bed frame or on the mattress pad 10 and the two sections 2b and 3b of the L-shaped parts 2, 3 come to lie directly above the mattress 6. Of the Distance between the sections 2b, 3b and the U-shaped part 4 corresponds approximately to that Thickness of the mattress 6. As can be seen from Fig. 2a, the two legs 4a, 4b of the U-shaped Part 4 approximately as long as the width of the mattress 6, which is the best stability for the Seat device and thus for the seated person. The length of the two sections 2b, 3b is chosen so that the distance between the backrest 5 and the edge of the bed is sufficiently large for the seated person.

Bei Anwendung der Sitzvorrichtung begibt sich die im Bett liegende Person zunächst in eine Seitenlage auf dem Bett bzw. wird in diese Seitenlage gebracht. Anschliessend wird die Sitzvorrichtung von der Längsseite des Bettes über die Matratze 6 geschoben. Hierauf wird die Person aufgerichtet und in eine Position gebracht, in der sie seitlich auf dem Bettrand sitzt und mit dem Rücken an die Rückenlehnen 5 lehnt. Dabei ist es möglich, die Füsse auf den Boden zu setzen. Sie kann dann selbständig in dieser Sitzposition verbleiben und fühlt sich wie auf einem Stuhl sitzend. Dies ist vor allem bei pflegebedürftigen und gebrechlichen Personen von Vorteil, da sie so eine sitzende Position einnehmen können, in der sie das Pflegepersonal betreuen und versorgen kann, ohne dass sie das Bett ganz verlassen müssen. In dieser Position stabilisiert die Person die Sitzvorrichtung zusätzlich, indem das auf die Matratze wirkende Körpergewicht die beiden Schenke 4a, 4b zwischen der Unterseite der Matratze und der Matratzenauflage 10 festklemmt. Eine besonders angenehme Sitzposition wird erreicht, wenn die Abschnitte 2a, 3a leicht nach hinten geneigt sind und die Rückenlehne 5 bogenförmig leicht nach hinten gewölbt ist.When using the seat device, the person lying in bed first moves into one Lateral position on the bed or is brought into this lateral position. Then the seat device pushed from the long side of the bed over the mattress 6. Then the person erected and brought into a position in which she sits on the side of the bed and with the Leaning back against the backrests 5. It is possible to put your feet on the floor. She can then remain in this sitting position independently and feels like she is on a chair sitting. This is particularly advantageous for people in need of care and frail as they can take a seated position in which they look after and care for the nursing staff can without having to leave the bed entirely. In this position the Person the seat device additionally by the body weight acting on the mattress two bars 4a, 4b between the underside of the mattress and the mattress cover 10 stuck. A particularly comfortable sitting position is achieved when the sections 2a, 3a are slightly inclined backwards and the backrest 5 is arched slightly backwards is.

Der Träger 1 kann aus einem einzigen Stück oder aus mehreren Stücken gefertigt sein. Wählt man für den Träger 1 ein Rohr mit einem Durchmesser in der Grössenordnung von 20 mm, kann er gemäss Fig. 1 ohne weiteres einstückig gefertigt werden. In einer anderen Ausführungsform könnte der Träger 1 aus zwei gleichen Stücken, bestehend je aus einem L-förmigen Teil 2 bzw. 3 und einem Schenke 4a bzw. 4b des Teils 4 gefertigt werden, die beispielsweise über einen U-förmigen Abschnitt miteinander verbunden sind.The carrier 1 can be made from a single piece or from several pieces. Elects a tube with a diameter of the order of 20 mm is used for the support 1, 1 it can be manufactured in one piece without further notice. In another embodiment the carrier 1 could consist of two identical pieces, each consisting of an L-shaped Part 2 or 3 and a bar 4a or 4b of part 4 are made, for example a U-shaped section are connected to each other.

Für den Teil 4 der Sitzvorichtung sind auch andere Ausführungsformen denkbar. So muss die Verbindung der beiden Schenkel 4a, 4b des Teils 4 nicht unbedingt U-förmig sein; die beiden Schenkel 4a, 4b können auch direkt miteinander verbunden sein, so dass der Teil 4 eine Dreieckform erhält. Der Teil 4 kann aber auch mit zwei freie Enden aufweisenden Schenkeln 4a, 4b ausgeführt werden, d.h. die U-förmige Verbindung zwischen den freien Enden der Schenke 4a, 4b gemäss Fig. 1 entfällt.Other embodiments are also conceivable for part 4 of the seat device. So it has to Connection of the two legs 4a, 4b of part 4 is not necessarily U-shaped his; the two Legs 4a, 4b can also be connected directly to one another, so that part 4 has a triangular shape receives. The part 4 can, however, also have legs 4a, 4b with two free ends be carried out, i.e. the U-shaped connection between the free ends of the leg 4a, 4b according to FIG. 1 is omitted.

Der Komfort der Sitzvorrichtung kann durch Anbringen von Armlehnen 9a, 9b (Fig.1) erhöht werden. Fig. 3 zeigt Einzelheiten einer solchen Ausführungsform. Am Abschnitt 2a des L-förmigen Teils 2 ist auf der gegen die Sitzfläche gerichteten Seite ein Längsschlitz 13 angebracht, z.B. eingefräst. Eine Armlehne 9a - z.B. mit zylindrischer Form und aus Holz - ist mit einer Halteplatte 14 - z.B. aus Metall - verbunden, die einen abgewinkelten Rastteil 15 mit einem Schlitz 16 aufweist. Die Breite des Rastteils 15 entspricht etwa dem Innendurchmesser des Rohres. Zum Anbringen der Armlehne 9 wird der Rastteil 15 durch den Längsschlitz 13 in den Abschnitt 2a eingesetzt. Ein senkrecht zur Halteplatte 14 und zur Rohrachse durch das Rohr des Abschnittes 2a ragender Bolzen 17 greift in den Schlitz 16 ein. Der Rastteil 15 lässt sich so entlang des Längsschlitzes 13 in Richtung der Rohrachse bewegen. Dabei ist die Lage des Bolzens 17 am Abschnitt 2a bezüglich des Längsschlitzes 13 so gewählt, dass die Halteplatte 14 in der gezeichneten Lage sich auf dem unteren Ende des Längsschlitzes 13 abstützt und in der oberen Lage um 90 Grad nach unten geschwenkt werden kann. Dadurch kann die Armlehne 9a bei Nichtgebrauch entweder eingeklappt oder durch Herausziehen des Bolzens 17 ganz entfernt werden, was beim Transport der Sitzvorrichtung von Vorteil ist. Der Bolzen 17 kann durch an seinen Enden angebrachte Splinte entfernbar fixiert werden. In gleicher Weise wird auch am Abschnitt 3a des L-förmigen Teils 3 eine Armlehne 9b angebracht.The comfort of the seat device can be increased by attaching armrests 9a, 9b (FIG. 1) become. Fig. 3 shows details of such an embodiment. At section 2a of the L-shaped Part 2 has a longitudinal slot 13 on the side facing the seat, e.g. milled in. An armrest 9a - e.g. with cylindrical shape and made of wood - is with a holding plate 14 - e.g. made of metal - connected an angled locking part 15 with a Has slot 16. The width of the locking part 15 corresponds approximately to the inner diameter of the tube. To attach the armrest 9, the locking part 15 is through the longitudinal slot 13 in the section 2a used. A perpendicular to the holding plate 14 and the tube axis through the tube of the Section 2a projecting bolt 17 engages in the slot 16. The locking part 15 can thus be along of the longitudinal slot 13 move in the direction of the tube axis. Here is the location of the bolt 17 selected on section 2a with respect to the longitudinal slot 13 so that the holding plate 14 in the drawn position is supported on the lower end of the longitudinal slot 13 and in the upper Position can be swiveled down 90 degrees. This allows the armrest 9a Not in use either folded in or removed completely by pulling out the bolt 17 become, which is an advantage when transporting the seat device. The bolt 17 can by the ends of the split pins are removably attached. In the same way is also on Section 3a of the L-shaped part 3 attached an armrest 9b.

Um die Sitzvorrichtung an verschiedene Breiten von Matratzen 6 anzupassen, sind in einer Weiterbildung der Erfindung die Abschnitte 2b, 3b in der Länge veränderbar ausgeführt. Einzelheiten hierzu zeigt Fig. 4 für den Abschnitt 3b. Der Abschnitt 3b ist vom Abschnitt 3a getrennt. Am freien Ende des horizontal verlaufenden Bereichs des Abschnittes 3a ist ein rohrförmiges Verbindungselement 7b, beispielsweise mittels einer Presspassung eingesetzt. Der Aussendurchmesser des Verbindungselementes 7b ist in dem aus dem Abschnitt 3a herausragenden Teil so gewählt, dass der Abschnitt 3b gleitend darüber gestülpt werden kann und so gegenüber dem Abschnitt 3a verschiebbar ist. Das Verbindungselement 7b weist zudem in bestimmten Abständen auf einer Linie angeordnete Bohrungen 18 auf, in die ein Stift 8 einer am Abschnitt 3b angebrachten Rastvorrichtung 19 (Fig. 5) eingreift. Der Stift 8 ist mit einem z.B. kugelförmigen Rastknopf 12 verbunden und verläuft axial in einer spiralförmigen Druckfeder 22 in einem Federraum 21 eines am Abschnitt 3b befestigten Aufsatzes 20. Fig. 5 zeigt ein Schnittbild der Rastvorrichtung 19 im eingerasteten Zustand, in welchem der Stift 8 in eine Bohrung 18 des Verbindungselementes 7b eingreift. Dabei liegt ein mit dem Stift 8 verbundener Anschlag 23 auf dem Abschnitt 3b auf. Die Druckfeder 22 ist zwischen dem Anschlag 23 und dem oberen Ende des Federraums 21 angeordnet. Beim Anheben des Rastknopfes 12 wird der Stift 8 entgegen der Federkraft aus der Bohrung 18 herausgezogen, worauf der Abschnitt 3b entsprechend der gegebenen Matratzenbreite verschoben werden kann. Beim Loslassen des Rastknopfes 12 greift der Stift 8 unter Wirkung der Federkraft in die gewünschte Bohrung des Verbindungselementes 7b ein. In gleicher Weise wird auch der Abschnitt 2b verschiebbar ausgeführt. Diese Ausführungsform der Erfindung erlaubt, die Rückenlehne 5 in Abhängigkeit von der Breite der Matratze 6 optimal in eine für die sitzende Person komfortable Position zu bringen.To adapt the seat device to different widths of mattresses 6 are in one Further development of the invention, the sections 2b, 3b are made variable in length. details 4 shows this for section 3b. Section 3b is separate from section 3a. At the free end of the horizontal region of section 3a is a tubular one Connecting element 7b, used for example by means of a press fit. The outside diameter of the connecting element 7b is in the protruding from the section 3a Part chosen so that section 3b can be slid over it and so opposite the section 3a is displaceable. The connecting element 7b also has certain Spaces on a line arranged holes 18 into which a pin 8 one at section 3b attached locking device 19 (Fig. 5) engages. The pin 8 is e.g. spherical Locking button 12 connected and extends axially in a spiral compression spring 22 in a spring chamber 21 of an attachment 20 attached to section 3b. FIG. 5 shows a sectional view of the latching device 19 in the locked state, in which the pin 8 in a bore 18 of the connecting element 7b engages. Here is a stop 23 connected to the pin 8 on the Section 3b. The compression spring 22 is between the stop 23 and the upper end of the Spring chamber 21 arranged. When the locking button 12 is raised, the pin 8 is counter to the Spring force pulled out of the bore 18, whereupon the section 3b according to the given Mattress width can be moved. When you release the locking button 12 engages the pin 8 under the action of the spring force in the desired bore of the connecting element 7b a. Section 2b is also designed to be displaceable in the same way. This embodiment the invention allows the backrest 5 depending on the width of the mattress 6 optimally in a position comfortable for the seated person.

Nach dem gleichen Prinzip kann die Sitzvorrichtung auch für verschiedene Dicken der Matratze 6 ausgestaltet werden. Hierzu werden die Abschnitte 2b, 3b nicht einstückig mit den Schenkeln 4a, 4b verbunden, sondern ebenfalls je über ein Verbindungselement, das beispielsweise in den nach unten gerichteten Teil des Abschnitts 2b bzw. 3b eingepresst ist und über das der nach oben gerichtete Teil des Schenkels 4a bzw. 4b gestülpt ist und auf diesem gleiten kann. Die Länge der Verbindungselemente sowie die Anzahl und der Abstand der daran angebrachten Bohrungen wird entsprechend den verschiedenen Dicken der Matratzen 6 gewählt.According to the same principle, the seat device can also be used for different mattress thicknesses 6 can be designed. For this purpose, the sections 2b, 3b are not made in one piece with the legs 4a, 4b, but also each via a connecting element, for example in the downward-facing part of section 2b or 3b is pressed in and via which the after part of the leg 4a or 4b directed upwards and can slide on it. The Length of the connecting elements as well as the number and the distance of the attached Bores are selected according to the different thicknesses of the mattresses 6.
