Abstract

A hospital bed features a bed frame that is provided with a movable back rest and a movable head rest. A mechanism ensures that the head rest and the back rest can be moved by means of a single motor. Lifting of the back rest begins after the head rest has reached the maximum raised position.

Description

Bei Pflegebetten ist der Liegerahmen, auf dem sich die Matratze befindet, in mehrere Abschnitte aufgeteilt. Hierdurch soll es möglich sein Füße und/oder Rücken gegenüber einem zentralen Bereich oder den Beinen anzuheben.For nursing beds, the lying frame on which the mattress is located is divided into several sections. This should make it possible to lift feet and / or back against a central area or the legs.

Dokument CH-A-682124 offenbart ein Bett mit einem Grundrahmen von mindestens einem darin durch einen Antrieb bewegbar angeordneten Teil eines Lattenrostes."document CH-A-682 124 discloses a bed having a base frame of at least one part of a slatted frame movably disposed therein by a drive. "

Zur Verstellung des Rückenbereiches wird ein Elektromotor verwendet, der über eine Schraubspindel den Rückenabschnitt anhebt oder absenkt. Für den Kopfabschnitt dagegen wird eine manuell zu betätigende Rasteinrichtung verwendet. Für den im Bett liegenden Patienten ist es damit nicht möglich das Kopfteil zu verstellen. Eine vollkommen flach liegende Position kann nur mit fremder Hilfe erreicht werden, wenn durch die Hilfsperson das Kopfteil flachgelegt wird. Umgekehrt ist auch eine Anhebung des Kopfabschnittes durch den Patienten selbst nicht möglich. Auch hierzu benötigt er eine Hilfskraft, die das Kopfteil in die aufgerichtete Position bringt. Insbesondere ist es für den Patienten auch unmöglich, beliebige Zwischenstellungen des Kopfteils zu erreichen.To adjust the back area, an electric motor is used, which raises or lowers the back section via a screw spindle. For the head section, however, a manually operated locking device is used. For the patient lying in bed it is therefore not possible to adjust the headboard. A completely flat lying position can only be achieved with outside help if the head part is laid flat by the helper. Conversely, an elevation of the head section by the patient is not possible. Again, he needs an assistant who brings the headboard in the upright position. In particular, it is also impossible for the patient to achieve any intermediate positions of the head part.

Ausgehend hiervon ist es Aufgabe der Erfindung ein Pflegebett gemäß dem Oberbegriff des Anspruchs 1, zu schaffen, bei dem mit Hilfe eines einzigen Antriebs sowohl der Rückenabschnitt als auch der Kopfabschnitt des Liegerahmens motorisch verstellbar ist.Based on this, it is an object of the invention to provide a nursing bed according to the preamble of claim 1, wherein by means of a single drive, both the back portion and the head portion of the reclining frame is adjustable by motor.

Bei dem neuen Pflegebett ist in der bekannten Weise der Liegerahmen, auf dem sich die Matratze befindet, in mehrere Abschnitte oder Segmente gegliedert. Eines der Segmente bildet den Rückenabschnitt, d.h. jenen Abschnitt auf dem der Rücken des Patienten liegt. An den Rückenabschnitt oder das Rückensegment schließt sich der Kopfabschnitt an, wobei die Scharnierachse zwischen den beiden Abschnitten bezogen auf einen im Bett liegenden Menschen etwa im Bereich des Halses verläuft.In the new nursing bed, the lying frame on which the mattress is located is divided into several sections or segments in the known manner. One of the segments forms the spine portion, i. the section on which the patient's back lies. The back section or the back segment is adjoined by the head section, wherein the hinge axis extends between the two sections in relation to a person lying in bed approximately in the area of the neck.

Zum Verstellen des Rückenabschnitts wird ein Linearantrieb verwendet, dessen Bewegungsachse unter einem spitzen Winkel zu dem Kopfabschnitt verläuft. Die Anordnung ist so getroffen, dass beim Ausfahren des Linearantriebs dessen bewegliches Ende sich in Richtung auf den Kopfabschnitt bewegt, also nach distal.To adjust the back portion, a linear drive is used whose axis of movement extends at an acute angle to the head portion. The arrangement is such that when the linear drive is extended, its movable end moves in the direction of the head section, that is to say distally.

Um die Bewegung des Kopfabschnittes zu erzwingen, greift der Linearantrieb über einen Zwischen- oder Schwenkhebel an dem Rückenabschnitt an. Von dem Schwenk- oder Zwischenhebel führt eine Koppelstrebe zu dem Kopfteil.In order to force the movement of the head section, the linear drive engages via an intermediate or pivot lever on the back portion. From the pivot or intermediate lever leads a coupling strut to the headboard.

Aufgrund dieser Anordnung wird eine sequentielle Bewegung des Kopfabschnitts und des Rückenabschnitts erreicht.Due to this arrangement, a sequential movement of the head portion and the back portion is achieved.

Wenn, ausgehend von der flachliegenden Stellung beider Liegerahmenabschnitte, der Linearantrieb in Gang gesetzt wird, bewegt sich zunächst der Kopfabschnitt in eine angehobene oder nach oben angewinkelte Stellung. Erst wenn die Endposition des Kopfabschnittes erreicht ist, beginnt sich auch der Rückenabschnitt zu heben. Damit ist der Patient in der Lage eine angenehme Kopfhaltung zu erreichen. Eine unergonomische Kopfhaltung mit flach liegendem Kopf bei angehobenem Rücken wird vermieden. Der Patient kann die entsprechenden Positionen über den Linearantrieb selbsttätig ohne fremde Hilfe einstellen.If, starting from the flat position of both Liegerahmenabschnitte, set the linear drive in motion is initially moved, the head portion in a raised or upwardly angled position. Only when the end position of the head portion is reached, also the back portion begins to lift. Thus, the patient is able to achieve a comfortable head posture. An unergonomic head position with flat lying head with raised back is avoided. The patient can adjust the corresponding positions automatically via the linear drive without external help.

Günstige konstruktive Verhältnisse ergeben sich, wenn der Rückenabschnitt zwei Längsholme aufweist, von denen jeder über ein zugehöriges Scharnier mit dem Zentralabschnitt verbunden ist.Favorable constructive conditions arise when the back portion has two longitudinal bars, each of which is connected via an associated hinge with the central portion.

Die Anlenkung des Rückenabschnitts insbesondere bei Pflegebetten mit drehbarem Liegerahmen, wie sie in der DE 103 30 759 beschrieben sind, gestaltet sich einfach, wenn der Rückenabschnitt zwei verlängerte Längsholme aufweist, die seitlich neben dem Kopfabschnitt verlaufen und über diesen hinausragen. An ihrem freien Ende sind die Längsholme durch eine Querstrebe miteinander verbunden. Der Kopfabschnitt ist zwischen den Längsholmen schwenkbar gelagert.The articulation of the back section, especially in nursing beds with rotatable lying frame, as shown in the DE 103 30 759 are described, designed simply when the back portion has two elongated longitudinal beams, which extend laterally adjacent to the head portion and project beyond this. At its free end, the longitudinal beams are connected by a cross brace. The head portion is pivotally mounted between the longitudinal beams.

Eine lastunabhängige Begrenzung für das Anheben des Kopfteils wird erreicht, wenn die Schwenkbewegung des Zwischenhebels im Sinne eines Aufrichtens oder Absenkens des Rückenabschnitts mittelbar oder unmittelbar begrenzt ist. Die Begrenzung kann mit Hilfe der Begrenzung der Schwenkbewegung des Kopfteils an dem Rückenabschnitt erfolgen oder indem an dem Zwischenhebel ein Anschlag ausgebildet ist, der das Anheben begrenzt.A load-independent limitation for the lifting of the head part is achieved when the pivoting movement of the intermediate lever in the sense of erecting or lowering the spine portion is directly or indirectly limited. The limitation can be made by means of limiting the pivotal movement of the head part on the back portion or by a stop is formed on the intermediate lever, which limits the lifting.

Das Absenken des Kopfabschnitts kann durch Anschläge begrenzt sein, die an den Längsholmen des Rückenabschnitts vorgesehen sind, oder durch einen weiteren Anschlag an dem Schwenkhebel.The lowering of the head portion may be limited by stops which are provided on the longitudinal beams of the back portion, or by another stop on the pivot lever.

Der Zwischenhebel kann über ein Tragscharnier an dem Rückenabschnitt anscharniert sein.The intermediate lever may be hinged to the spine portion via a support hinge.

Ein Antriebsscharnier kann den Schwenkhebel mit dem Linearantrieb verbinden, wobei die Achsen des Tragscharniers und die des Antriebsscharniers in einer gemeinsamen Ebene liegen.A drive hinge may connect the pivoting lever to the linear drive with the axes of the support hinge and the drive hinge in a common plane.

Günstige Kraftverhältnisse ergeben sich, wenn die Ebene, in der die beiden Achsen liegen, einen Winkel mit dem Rückenabschnitt einschließen der größer als 60° vorzugsweise größer als 70° ist. Hierdurch wird erreicht, dass ohne sonstige Belastung, in jedem Falle zunächst der Kopfabschnitt hochfährt, ehe sich der Rückenabschnitt beginnt anzuheben.Favorable power relations arise when the plane in which the two axes lie encloses an angle with the back section which is greater than 60 °, preferably greater than 70 °. This ensures that without any other load, in each case, first the head portion starts up before the back portion begins to lift.

Der Zwischenhebel ist über ein Koppelstrebenscharnier mit der Koppelstrebe verbunden. Die Achse des Koppelstrebenscharniers liegt in einer Ebene in der auch die Achse des Tragscharniers liegt. Die so gebildete Ebene kann mit dem Rückenabschnitt einen Winkel größer 80° einschließen, wenn sich der Rückenabschnitt und der Kopfabschnitt in einer gemeinsamen Ebene liegen, d.h. der Rückenabschnitt vollständig abgesenkt ist.The intermediate lever is connected via a coupling strut hinge with the coupling strut. The axis of the coupling strut hinge lies in a plane in which the axis of the support hinge is located. The plane thus formed may include an angle greater than 80 ° with the spine portion when the spine portion and the spine portion are in a common plane, i. the back portion is completely lowered.

Der Zwischenhebel kann in einfachster Weise von einer Platte gebildet sein, die insgesamt drei Bohrungen enthält und durch die Scharnierbolzen hindurch führen. Um ein seitliches Verkippen des Zwischenhebels zu vermeiden, kann jene Bohrung, die mittelbar das Tragscharnier bildet, eine Büchse enthalten, die mit der Platte starr verbunden ist.The intermediate lever can be formed in the simplest way by a plate which contains a total of three holes and pass through the hinge pin. To a side To avoid tilting the intermediate lever, that bore, which indirectly forms the support hinge, may include a sleeve which is rigidly connected to the plate.

Wenn die Koppelstrebe aus zwei deckungsgleichen Teilstreben besteht, die durch Distanzelemente verbunden sind, sind spezielle Gabelköpfe an den Enden entbehrlich. Insbesondere ist es auf diese Weise möglich auch kompliziert verlaufende Koppelstreben zu erzeugen, damit die Koppelstrebe an anderen, quer verlaufenden Strukturelementen des Bettes vorbeigelangen kann. Die Verwendung von zwei deckungsgleichen Teilstreben ermöglicht auf einfache Weise die Herstellung der jeweiligen Teilstrebe als lasergeschnittenes Teil. Da jede Teilstrebe für sich verhältnismäßig dünn ist, ist der Energieaufwand zum Schneiden gering und es können sehr genau maßhaltige Teile erzeugt werden.If the coupling strut consists of two congruent partial struts, which are connected by spacers, special clevises at the ends are unnecessary. In particular, it is possible in this way to produce complicated running coupling struts, so that the coupling strut can get past other, transverse structural elements of the bed. The use of two congruent partial struts allows the production of the respective partial strut as a laser-cut part in a simple manner. Since each strut is relatively thin for itself, the energy required for cutting is low and it can be produced very accurate dimensionally stable parts.

Die Koppelstrebe kann beim Kopfabschnitt an einem Hebel angreifen, der starr mit dem Kopfabschnitt verbunden ist. Dieser Hebel sitzt zweckmäßigerweise an einer Querstrebe des Kopfabschnittes in der Nähe der Scharnierachse bezüglich derer der Kopfabschnitt gegenüber dem Rückenabschnitt bewegbar ist.The coupling strut can engage the head portion on a lever which is rigidly connected to the head portion. This lever is expediently located on a transverse strut of the head section in the vicinity of the hinge axis with respect to which the head section is movable relative to the back section.

Die wirksame Hebellänge, über die die Koppelstrebe an dem Kopfabschnitt angreift und das Drehmoment einleitet, kann zwischen dem 0,8 und dem 1,5-fachen des Achsabstandes liegen, den das Koppelstrebenscharnier von dem Tragscharnier hat.The effective lever length over which the coupling strut engages the head portion and initiates the torque may be between 0.8 and 1.5 times the axial distance that the coupling strut hinge has from the support hinge.

Der Achsabstand zwischen dem Tragscharnier und dem Antriebsscharnier liegt zweckmäßigerweise zwischen 20 mm und 80 mm. Je kleiner dieser Abstand ist, umso größer sind die Kräfte zum Aufstellen des Kopfabschnitts, was dazu führen kann, dass im unbelasteten Zustand nicht zunächst der Kopfabschnitt aufgerichtet wird, wenn der Antriebsmotor in Gang gesetzt wird.The axial distance between the support hinge and the drive hinge is suitably between 20 mm and 80 mm. The smaller this distance, the larger the forces to set up the head portion, which can lead to that in the unloaded state, not the head portion is first erected when the drive motor is set in motion.

Als Linearantrieb dient vorzugsweise ein Schraubspindelantrieb. Dieser setzt sich in bekannter Weise aus einem über einen permanent erregten Gleichstrommotor angetriebenen Schneckengetriebe und einem Schraubspindelgetriebe zusammen. Das Schneckenrad sitzt drehfest auf der Schraubspindel. Auf dieser läuft eine drehgesicherte Mutter, die mit einem Ausschubrohr gekuppelt ist um die Bewegung des Motors in eine Linearbewegung umzuwandeln.As a linear drive is preferably a screw drive. This is composed in a known manner from a driven via a permanent-magnet DC motor worm gear and a Schraubspindelgetriebe. The worm wheel is non-rotatably mounted on the screw spindle. On this run a non-rotating nut, which is coupled with a Ausschubrohr to convert the movement of the motor into a linear movement.

Der Linearantrieb kann so gestaltet werden, dass er lediglich in der Lage ist, Druckkräfte auf den Rückenabschnitt zu übertragen.The linear drive can be designed so that it is only able to transmit compressive forces on the back portion.

Fig. 1 zeigt in einer perspektivischen Darstellung das erfindungsgemäße Dreh- und Aufstehbett 1 in der Liegestellung, während Fig. 2 das Bett 1 in der Sitz- oder Sesselstellung wiedergibt. Fig. 1 shows in a perspective view of the inventive turning and Aufstehbett 1 in the lying position, while Fig. 2 the bed 1 in the seat or chair position reproduces.

Das Bett 1 weist eine Bettumrandung 2 mit einem Kopfteil 3, einem Fußteil 4 sowie Seitenwänden 5 und 6 auf. Die dem Betrachter zugekehrte Seitenwand 5 befindet sich in der Liegestellung. Die Seitenwand 5 steht in einem größeren Abstand zum Boden, womit zwischen der Unterkante der Seitenwand 5 und dem Boden ein Spalt besteht, der es dem Pflegepersonal ermöglicht, die Fußspitzen unter das Bett zu stellen. Die Seitenwand 5 ist beweglich gelagert und gelangt in der Sesselstellung des Bettes 1 in einer weiter nach unten verschobene Position, wie dies Fig. 2 erkennen lässt. Die spezielle Lagerung der Seitenwand 5 ist beispielsweise ausführlich in der DE 199 12 987 A1 erläutert.The bed 1 has a bed border 2 with a head part 3, a foot part 4 and side walls 5 and 6. The viewer facing side wall 5 is located in the lying position. The side wall 5 is at a greater distance from the ground, whereby there is a gap between the lower edge of the side wall 5 and the floor, which allows the nursing staff to put the toes under the bed. The side wall 5 is movably mounted and arrives in the chair position of the bed 1 in a further downwardly shifted position, as this Fig. 2 lets recognize. The special storage of the side wall 5 is for example in detail in the DE 199 12 987 A1 explained.

Innerhalb der Bettumrandung 2 befindet sich ein Heber 8, der ausschnittsweise in Fig. 2 zu erkennen ist. Auf dem Heber 8 ist über ein nicht weiter erkennbares Drehscharnier ein Liegerahmen 9 befestigt, der einer Matratze 11 trägt. Der Heber 8 dient dazu, den Liegerahmen 9 samt der darauf befindlichen Matratze 11 in unterschiedliche Höhen zu bringen. Der Aufbau des Hebers ist beispielsweise in der DE 10 2004 019 144 A1 ausführlich erläutert, auf die insoweit Bezug genommen wird.Within the Bedumrandung 2 is a lifter 8, the fragmentary in Fig. 2 can be seen. On the lifter 8, a reclining frame 9 is attached via a not further recognizable rotary hinge, which carries a mattress 11. The lifter 8 serves to bring the reclining frame 9 together with the mattress 11 thereon to different heights. The structure of the lift is for example in the DE 10 2004 019 144 A1 explained in detail, to which reference is made.

Der Liegerahmen 9 gliedert sich in mehrere, gegeneinander bewegliche Abschnitte. Die Bezeichnungen der einzelnen Abschnitte entsprechen im Wesentlichen der Bezeichnung der darauf ruhenden Körperteile eines im Bett liegenden Menschen.The lying frame 9 is divided into several, mutually movable sections. The names of the individual sections essentially correspond to the description of the body parts resting on it of a person lying in bed.

Unmittelbar am Kopfende befindet sich ein schwenkbarer und in Fig. 1 nach oben geschwenkter Kopfabschnitt 12, an den sich in Richtung auf das Fußende ein Rückenabschnitt 13 anschließt. Der Rückenabschnitt 13 ist an einem Zentralabschnitt 14 anscharniert, der seinerseits unmittelbar über das Drehscharnier mit dem Heber oder Lifter 8 verbunden ist. Auf den Zentralabschnitt 14 folgt ein Oberschenkelabschnitt 15, der in einen Unterschenkelabschnitt 16 übergeht. Schließlich bildet die Liegefläche noch ein Fußabschnitt 17. Im gedrehten Zustand bleibt der Fußabschnitt 17 ortsfest im Bett, während lediglich die Abschnitte 12 bis 16 bewegt werden.Immediately at the head end is a swiveling and in Fig. 1 upwardly pivoted head portion 12, to which a back portion 13 connects in the direction of the foot end. The back portion 13 is hinged to a central portion 14, which in turn is connected directly via the rotary hinge with the lifter or lifter 8. The central section 14 is followed by a thigh section 15, which merges into a lower leg section 16. Finally, the lying surface still forms a foot section 17. In the rotated state, the foot section 17 remains stationary in bed, while only the sections 12 to 16 are moved.

Der Liegerahmen 9 ist auf einem Zwischenrahmen 18 aufgebaut, der seinerseits auf dem auch nicht dargestellten Drehscharnier sitzt, das den Zwischenrahmen 18 mit dem Heber 8 verbindet. Der Zwischenrahmen 18 besteht, wie die Figur 3 erkennen lässt, aus zwei zueinander parallelen Längsholmen 19, von denen wegen der Seitenansicht lediglich einer der beiden Längsholme zu erkennen ist.The lying frame 9 is constructed on an intermediate frame 18, which in turn on the not shown Rotary hinge sits, which connects the intermediate frame 18 with the lifter 8. The intermediate frame 18 is made as the FIG. 3 can be seen from two mutually parallel longitudinal beams 19, of which only one of the two longitudinal beams can be seen because of the side view.

Der Zentralabschnitt umfasst zwei Längsholme 19, die auf zugehörigen Auslegern 20 sitzen, die an der seitlichen Flanke des Zwischenrahmens 18 befestigt ist. Der Abstand der Längsholme 19 voneinander entspricht der Breite der Liegefläche und ist etwas schmäler als die Breite der Matratze 11.The central portion comprises two longitudinal spars 19 which sit on associated cantilevers 20 attached to the lateral flank of the intermediate frame 18. The distance between the longitudinal bars 19 from one another corresponds to the width of the lying surface and is slightly narrower than the width of the mattress eleventh

Der Zentralabschnitt 14, der durch die beiden zueinander parallelen Holme 21 gebildet wird, ist bezüglich des Zwischenrahmens 18 unbeweglich.The central portion 14, which is formed by the two parallel spars 21, is immovable with respect to the intermediate frame 18.

Der Oberschenkelabschnitt 15 besteht ebenfalls aus zwei zueinander parallelen Holmen 22, von denen wiederum lediglich der dem Betrachter zugekehrte Holm 22 in der Fig. zu erkennen ist. Der andere Holm befindet sich auf der Speicherhöhe in der Zeichenebene dahinter.The thigh portion 15 also consists of two mutually parallel bars 22, of which in turn only the viewer facing Holm 22 can be seen in the Fig. The other spar is located at the storage level in the drawing plane behind it.

Die jeweils auf derselben Seite liegenden Holme 21 und 22 sind über Scharniere 23 auf beiden Seiten des Liegerahmens 9 gelenkig miteinander verbunden. Die Scharnierachsen der beiden Scharniere 23 liegen koaxial zueinander.The respectively lying on the same side spars 21 and 22 are hingedly connected to each other via hinges 23 on both sides of the reclining frame 9. The hinge axes of the two hinges 23 are coaxial with each other.

Auf jeder Seite ist über Scharnier mit einer Scharnierachse 24 an den betreffenden Holm 22 ein Holm 25 anscharniert, der zusammen mit einen auf der anderen Seite des Bettes liegenden dazu parallelen Längsholm 25 die seitliche Begrenzung des Unterschenkelabschnittes 16 bildet.On each side hinged by hinge with a hinge axis 24 to the relevant spar 22, a spar 25 which forms the lateral boundary of the lower leg portion 16 together with a lying on the other side of the bed parallel thereto longitudinal beam 25.

Die beiden Holme 25 sind durch eine Quertraverse 26 miteinander verbunden. Vom freien Ende des Unterschenkelabschnittes 16 führen im Abstand zueinander zwei zueinander parallele Schienen 27 in Richtung auf den Zentralabschnitt 14. In ihnen laufen Rollen einer Schwenkhebelanordnung 28, die bei 29 am Fußende des Zwischenrahmens 18 zwischen dessen Längsholmen 19 anscharniert ist. Die Achse des Scharnierlagers 29 liegt parallel zu den Scharnierachsen 23 und 24, so dass die Hebelanordnung 28 entsprechend geschwenkt werden kann. Beim Herauf- und Herunterschwenken werden das Oberschenkelabscnitt 15 und das Unterschenkelabschnitt 16 unter Ausbildung eines Knieknicks, wie in Fig. 3 gezeigt, angehoben oder in der gedrehten Stellung gemäß Fig. 2 abgesenkt. In dieser Stellung führt der Unterschenkelabschnitt 16 vertikal nach unten.The two spars 25 are connected by a crossbeam 26 with each other. From the free end of the lower leg portion 16 lead at a distance to each other two mutually parallel rails 27 in the direction of the central portion 14. In them run rollers of a pivot lever assembly 28 which is hinged at 29 at the foot of the intermediate frame 18 between the longitudinal beams 19. The axis of the hinge bearing 29 is parallel to the hinge axes 23 and 24, so that the lever assembly 28 can be pivoted accordingly. When swaying up and down, the thigh portion 15 and the lower leg portion 16 become a knee bend, as in FIG Fig. 3 shown, raised or in the rotated position according to Fig. 2 lowered. In this position, the lower leg portion 16 leads vertically downwards.

Am zum Kopfende zeigenden Ende des Zentralabschnittes 14 ist der Rückenabschnitt 13 anscharniert. Die Scharnierachse ist bei 29 zu erkennen. Der Rückenabschnitt 13 besteht aus zwei zueinander parallelen Holmen 31, von denen in Fig. 3 lediglich der auf der linken Bettseite zu erkennen ist, während der dazu parallele Holm 31 aus Fig. 2 ersichtlich ist.At the end of the central portion 14 facing the head end, the back portion 13 is hinged. The hinge axis can be seen at 29. The back section 13 consists of two mutually parallel bars 31, of which in Fig. 3 only to be recognized on the left side of the bed, while the parallel to the spar 31 from Fig. 2 is apparent.

Diese beiden Holme 31 sind unter anderem durch eine Querstrebe 33 miteinander verbunden, die nahe dem distalen Ende des Rückenabschnitts 13 liegt. Ferner haben sie eine Länge die größer ist, als es für den Rückenabschnitt 13 erforderlich ist. Sie reichen bis über den beweglichen Kopfabschnitt 12 hinaus und sind dort über eine weitere Querstrebe 34 verbunden.These two spars 31 are interconnected inter alia by a transverse strut 33, which is located near the distal end of the spine portion 13. Further, they have a length which is larger than required for the back portion 13. They extend beyond the movable head section 12 and are connected there via a further transverse strut 34.

Der Kopfabschnitt 12 ist zwischen den beiden zueinander parallelen Holmen 31 schwenkbar gelagert. Sein Scharnier- oder Beugegelenk 35 ist in Fig. 3 angedeutet. Es wird beispielsweise durch durch den jeweiligen Holm 31 hindurch gesteckte Bolzen gebildet. Mittels des Scharniergelenks 35 kann der Kopfabschnitt 12 aus einer Stellung, in der die aufgelegte Matratze 11, die in gerader Verlängerung des Rückenabschnitts 13 liegt, dort in eine angehobene Stellung gebracht werden, wie sie in den Fig. 1 und 2 gezeigt ist. In dieser Stellung ist die Matratze 11 im Kopfabschnitt entsprechend leicht, ca. 15° bis 20° nach oben abgewinkelt. Die Biegestelle liegt ergonomisch an einer günstigen Stelle. Bei einem im Bett liegenden Patienten etwa im Bereich der Halswirbelsäule.The head portion 12 is between the two to each other parallel spars 31 pivotally mounted. Its hinged joint 35 is in Fig. 3 indicated. It is formed, for example, by bolts inserted through the respective spar 31. By means of the hinge joint 35, the head portion 12 from a position in which the laid mattress 11, which lies in straight extension of the back portion 13, there are brought into a raised position, as shown in the Fig. 1 and 2 is shown. In this position, the mattress 11 in the head section is correspondingly light, about 15 ° to 20 ° angled upward. The bending point is ergonomically located at a convenient location. In a patient lying in bed, for example, in the area of the cervical spine.

Zum Bewegen des Lifters 8, zum Drehen des Liegerahmens 9 aus der Bettstellung gemäß Fig. 1 in die Stuhlstellung nach Fig. 2 sowie zum Bewegen des Oberschenkelabschnitts 15 und des Unterschenkelabschnitts 16 sind eine Anzahl von Spindelhubmotoren vorgesehen, die im Einzelnen nicht gezeigt sind, da dies zum Verständnis der Erfindung nicht erforderlich ist. Diese Spindelhubmotoren werden über eine zentrale Mikroprozessorsteuerung über einer Handbedienung angesteuert.To move the lifter 8, to rotate the reclining frame 9 from the bed position according to Fig. 1 in the chair position Fig. 2 and for moving the thigh portion 15 and the lower leg portion 16, a number of Spindelhubmotoren are provided, which are not shown in detail, since this is not necessary for understanding the invention. These Spindelhubmotoren be controlled via a central microprocessor control via a manual operation.

Zum Bewegen des Rückenabschnitts 13 ist ebenfalls ein Spindelhubmotor vorgesehen, von dem lediglich das starre Führungsrohr 36 und da bewegliche und teleskopartig ausfahrbare Hubrohr 37 erkennbar sind. Der schwenkbare Anlenkungspunkt für den Motor ist verdeckt.To move the back section 13, a spindle lifting motor is also provided, of which only the rigid guide tube 36 and the movable and telescopically extendable lifting tube 37 can be seen. The pivotable articulation point for the engine is covered.

Die kinematische Verbindung zwischen dem Hubrohr 37 und dem Rückenabschnitt 13 sowie dem Kopfabschnitt 12 ist im Einzelnen in Fig. 4 vergrößert und im Ausschnitt gezeigt.The kinematic connection between the lifting tube 37 and the back portion 13 and the head portion 12 is in detail in Fig. 4 enlarged and shown in the clipping.

Fig. 4 zeigt einen Betätigungsmechanismus 43 vergrößert und im Ausschnitt, der dazu eingerichtet ist, eine sequentielle Bewegung des Kopfabschnittes 12 und des Rückenabschnittes 13 zu erreichen. Zu dem Betätigungsmechanismus 43 gehören ein schwenkbarer Zwischenhebel 44 sowie eine Koppelstrebe 45. Fig. 4 shows an actuating mechanism 43 enlarged and in the cut-out, which is adapted to achieve a sequential movement of the head portion 12 and the back portion 13. To the actuating mechanism 43 includes a pivotable intermediate lever 44 and a coupling strut 45th

Von dem Zwischenrahmen 18 ist dessen auf der rechten Bettseite befindlicher Längsholm 19 zu erkennen. Der dazu parallele auf der linken Bettseite befindliche Längsholm 19 ist weggenommen, um den Blick auf die Betätigungseinrichtung 43 nicht zu verdecken.Of the intermediate frame 18 whose located on the right side bed longitudinal beam 19 can be seen. The parallel thereto on the left side of the bed longitudinal beam 19 is removed so as not to obscure the view of the actuator 43.

Der Zwischenhebel 44 ist an der Verbindungs- oder Querstrebe 33 schwenkbar gelagert. Die Strebe 33 befindet sich, wie die Figur erkennen lässt, in einem kurzen Abstand neben der Scharnierachse 35 in Richtung auf den Zentralabschnitt 15 versetzt. Etwa mittig sind an der Querstrebe 33 im Abstand zueinander zwei Laschen 47 angeschweißt, die in Richtung auf den Zentralabschnitt 14 zeigen. Zwischen ihnen ist auf einem durchgesteckten zylindrischen Bolzen 48 der Zwischenhebel 44 gelagert.The intermediate lever 44 is pivotally mounted on the connecting or transverse strut 33. The strut 33 is, as the figure can be seen, offset at a short distance next to the hinge axis 35 in the direction of the central portion 15. Approximately in the middle, two tabs 47 are welded to the cross member 33 at a distance from each other, pointing in the direction of the central portion 14. Between them, the intermediate lever 44 is mounted on a plugged cylindrical pin 48.

Der Zwischenhebel 44 hat die Gestalt einer angenähert rechteckigen Platte mit einer rechteckigen Ausnehmung bei 49. Die Ausnehmung 49 lässt eine gerade Anschlagfläche 50 entstehen, die mit der Unterseite der im Querschnitt rechteckigen Querstrebe 33 zusammenwirkt, um die Schwenkbewegung des Zwischenhebels 44 im Gegenuhrzeigersinn, bezogen auf die Darstellung, zu begrenzen.The intermediate lever 44 has the shape of an approximately rectangular plate with a rectangular recess at 49. The recess 49 can be a straight stop surface 50 is formed, which cooperates with the underside of the cross-sectionally rectangular cross member 33 to the pivotal movement of the intermediate lever 44 in the counterclockwise direction, based on the presentation, limit.

Der Zwischenhebel 44 enthält insgesamt drei Bohrungen 51, 52 und 53, mit denen einzelne Scharniere realisiert sind. Durch die Bohrung 53 führt eine Büchse 54 hindurch, die beispielsweise mit dem Zwischenhebel 44 verschweißt ist. Die Länge der Büchse 54 entspricht dem Abstand der starren Laschen 47. Die Büchse 54 dient dazu, den Zwischenhebel 54 kippsicher auf dem Steckbolzen 48 zu lagern. Auf diese Weise wird sichergestellt, dass der Zwischenhebel 44 lediglich eine Bewegung um die Achse des Bolzens 48, und damit parallel, zu den sonstigen Scharnierachsen des Liegerahmens 9 vollführen kann.The intermediate lever 44 includes a total of three holes 51, 52 and 53, with which individual hinges are realized. Through the bore 53 performs a sleeve 54 through which is welded, for example, with the intermediate lever 44. The length of the sleeve 54 corresponds to the distance of the rigid tabs 47. The sleeve 54 serves to store the intermediate lever 54 tilt-proof on the locking pin 48. In this way it is ensured that the intermediate lever 44 can perform only a movement about the axis of the bolt 48, and thus parallel to the other hinge axes of the reclining frame 9.

In das Hubrohr 37 des Schraubspindelmotors ist ein Gabelkopf 56 eingeschraubt, der mit seinem Gabelende den Zwischenhebel 44 übergreift. Durch die miteinander fluchtenden Bohrungen führt ein zylindrischer Gelenkbolzen 57, der auf diese Weise eine scharnierartige Verbindung zwischen dem Gabelkopf 56 und dem Schwenkhebel 44 herstellt.In the lifting tube 37 of the Schraubspindelmotors a clevis 56 is screwed, which engages over the intermediate lever 44 with its fork end. Through the aligned bores performs a cylindrical hinge pin 57, which produces in this way a hinge-like connection between the clevis 56 and the pivot lever 44.

Mit Hilfe der Koppelstrebe 45 wird die Schwenkbewegung des Zwischenhebels 44 auf den Kopfabschnitt 12 übertragen. Von dem Kopfabschnitt 12 ist der linke der beiden Längsholme 39 zu sehen, der wie der andere als L-profil ausgeführt ist. Die beiden Längsholme 39 sind über eine Querstrebe 58 miteinander verbunden. Die Querstrebe 58 befindet sich in der Nähe des Scharnierbolzens 35. An der Querstrebe 58 ist eine Lasche 59 befestigt, die in Richtung auf den Schwenk- oder Zwischenhebel 44 zeigt. Sie ist mit einer Querbohrung versehen, in der ein Zylinderbolzen 61 steckt, der die Verbindung zwischen der Lasche 59 und der Koppelstrebe 45 herstellt.With the help of the coupling strut 45, the pivotal movement of the intermediate lever 44 is transmitted to the head portion 12. From the head portion 12 of the left of the two longitudinal beams 39 can be seen, which is designed as the other as L-profile. The two longitudinal members 39 are connected to one another via a transverse strut 58. The cross strut 58 is located in the vicinity of the hinge pin 35. On the cross strut 58, a tab 59 is fixed, which points in the direction of the pivot or intermediate lever 44. It is provided with a transverse bore in which a cylinder pin 61 inserted, which establishes the connection between the tab 59 and the coupling strut 45.

Die Koppelstrebe 45 besteht aus zwei im Abstand zueinander verlaufenden und deckungsgleichen Teilstreben 62 und 63, die über mehrere Distanzstücke 64 auf Abstand entsprechend der Dicke des Schwenkhebels 44 bzw. der Lasche 59 gehalten werden. Mittels durchführender Niete 65 sind die beiden Teilstreben 62 und 63 starr miteinander verbunden.The coupling strut 45 consists of two spaced apart extending and congruent part struts 62 and 63, which are held over a plurality of spacers 64 at a distance corresponding to the thickness of the pivot lever 44 and the tab 59. By means of performing rivet 65, the two partial struts 62 and 63 are rigidly interconnected.

Die Koppelstrebe 45 enthält auch in den beiden Teilstreben 62 und 63 in der Nähe des Schwenkhebels 44 eine entsprechende Durchgangsbohrung. Ein durch diese Bohrungen sowie durch die Bohrung 51 durchführender Zylinderstift 66 bildet das Scharnier zum gelenkigen Verbinden der Koppelstrebe 45 mit dem Zwischenhebel 44.The coupling strut 45 also contains a corresponding through bore in the two partial struts 62 and 63 in the vicinity of the pivoting lever 44. A through this holes and through the bore 51 performing cylinder pin 66 forms the hinge for articulated connection of the coupling strut 45 with the intermediate lever 44th

Der wirksame Radius unter dem die Koppelstrebe 45 an dem Kopfabschnitt 12 angreift, ist etwa genauso groß wie der Abstand zwischen der Bohrung 53 und der Bohrung 52. Die Anordnung ist etwa so getroffen, dass der Schwenk- oder Zwischenhebel 44 denselben Winkelbereich durchläuft, wie der Kopfabschnitt 12.The effective radius under which the coupling strut 45 acts on the head portion 12 is about the same size as the distance between the bore 53 and the bore 52. The arrangement is made such that the pivot or intermediate lever 44 passes through the same angular range as the Head section 12.

Um ein Durchfallen des Kopfabschnitts 12 nach unten zu verhindern, sitzen an dem distalen Ende der Längsholme 31 Anschläge 67, auf die sich die Längsholme 39 des Kopfabschnitts auflegen, wenn die Liegefläche vollkommen eben sein soll.In order to prevent falling through of the head portion 12 down, sitting at the distal end of the longitudinal members 31 stops 67 on which hang the longitudinal members 39 of the head section, when the lying surface should be completely flat.

Die Funktionsweise ist wie folgt:The operation is as follows:

In der Liegeposition ist der für den Rückenabschnitt 13 zuständige Schraubspindelantrieb vollständig eingefahren, d.h. das Hubrohr 37 ist soweit zurückgezogen, dass der Kopfabschnitt 12 mit seinen beiden Längsholmen 39 auf den Anschlägen 67 aufliegen kann. Vorzugsweise ist um die Justierung zu vereinfachen der entsprechende Schraubspindelantrieb als entkoppelter Antrieb ausgeführt, in dem Sinne, dass lediglich eine Druckkraft auf das Hubrohr 37 ausgeübt werden kann. Der Motor selbst kann damit in eine praktisch beliebige Endlage zurücklaufen, ohne dass es in der Betätigungseinrichtung 43 zu Verspannungen kommen kann.In the lying position of the responsible for the back portion 13 screw drive is fully retracted, ie the lifting tube 37 is pulled back so far that the head portion 12 can rest with its two longitudinal members 39 on the stops 67. Preferably, the adjustment To simplify the corresponding screw drive as a decoupled drive running, in the sense that only a compressive force on the lifting tube 37 can be exercised. The motor itself can thus run back into a practically arbitrary end position, without it being possible for tension to occur in the actuating device 43.

In der abgesenkten Stellung liegt außerdem der Rückenabschnitt 13 mit der Querstrebe 33 auf der Oberseite der Längsholme 19 des Zwischenrahmens 18 auf.In the lowered position, furthermore, the back section 13 with the transverse strut 33 rests on the upper side of the longitudinal struts 19 of the intermediate frame 18.

Die Verbindungsebene, in denen die Achsen der Bohrungen 53 und 52 liegen, verläuft gegenüber einer Senkrechten auf dem abgesenkten Rückenabschnitt 13 unter einem Winkel von ca 15°.The connecting plane, in which the axes of the bores 53 and 52 are located, runs at an angle of approximately 15 ° with respect to a vertical on the lowered back section 13.

Wenn in dieser Position der betreffende Spindelhubmotor in Gang gesetzt wird, um das Hubrohr 37 auszuschieben, das unter einem spitzen Winkel von ca. 30° gegenüber der Ebene des Rückenabschnitts 12 angreift, wird zunächst der Zwischenhebel 44, bezogen auf die Darstellung nach Fig. 4 im Gegenuhrzeigersinn verschwenkt. Die Schwenkbewegung des Zwischenhebels 44 wird über die Koppelstrebe 45 auf die Lasche 59 des Kopfabschnittes 12 übertragen. Der Kopfabschnitt 12 wird entsprechend der Schwenkbewegung des Zwischenhebels 44 bzw. dem Ausfahrhub des Hubrohrs 37 aus der flach liegenden Stellung angehoben. Wie weit der Kopfabschnitt 12 angehoben werden soll, wird durch den Bewegungshub des Hubrohrs 37 gesteuert. Wenn der Benutzer eine angenehme Kopfhaltung erreicht hat, kann er durch ein entsprechendes Loslassen der jeweiligen Steuertaste den Spindelhubmotor stillsetzen und damit die Hubbewegung des Hubrohrs 37 beenden. Dadurch kann in der Liegeposition ein für den im Bett liegenden Menschen angenehme Kopfhaltung, beispielsweise zum Schlafen, erreicht werden. Der Benutzer ist nicht auf fremde Hilfe zum Einstellen der Kopfanhebung angewiesen.If in this position, the respective Spindelhubmotor is set in motion to eject the lifting tube 37, which acts at an acute angle of about 30 ° relative to the plane of the back portion 12, first the intermediate lever 44, based on the illustration to Fig. 4 pivoted counterclockwise. The pivotal movement of the intermediate lever 44 is transmitted via the coupling strut 45 on the tab 59 of the head portion 12. The head portion 12 is raised in accordance with the pivotal movement of the intermediate lever 44 and the extension stroke of the lifting tube 37 from the flat position. How far the head portion 12 is to be raised, is controlled by the movement stroke of the lifting tube 37. If the user has reached a comfortable head posture, he can stop by a corresponding release of the respective control button the Spindelhubmotor and thus stop the lifting movement of the lifting tube 37. This can be in the lying position one for the comfortable lying in bed, for example, to sleep, can be achieved. The user is not dependent on outside help to adjust the head lift.

Wenn der Spindelhubmotor lange genug angeschaltet bleibt, wird das Hubrohr 37 soweit ausgefahren, bis sich der Zwischenhebel 44 mit seiner Anschlagfläche 50 an der Unterseite der Querstrebe 33 anlehnt. Damit ist die maximale Verschwenkung des Zwischenhebels 44 gegen über dem Längsholm 31 des Rückenabschnitts 12 erreicht. Diese Schwenkbewegung entspricht einem Aufrichten des Kopfteils um ca. 15° bis maximal 20°, wobei 20° eher schon zuviel ist.If the Spindelhubmotor remains switched on long enough, the lifting tube 37 is extended so far until the intermediate lever 44 with its stop surface 50 on the underside of the cross member 33 is based. Thus, the maximum pivoting of the intermediate lever 44 is achieved with respect to the longitudinal beam 31 of the back portion 12. This pivotal movement corresponds to an erection of the head part by about 15 ° to a maximum of 20 °, with 20 ° is already too much.

Eine weitere Betätigung des entsprechenden Antriebs, verbunden mit einem weiteren Ausschieben des Hubrohrs 37, führt nunmehr dazu, dass, nachdem das Kopfteil 12 maximal hochgestellt ist, auch das Rückenabschnitt 13 beginnt sich anzuheben solange, bis der Benutzer den betreffenden Antrieb wieder still setzt.Further actuation of the corresponding drive, connected to a further pushing out of the lifting tube 37, now leads to that, after the head part 12 is maximally raised, and the back portion 13 begins to lift until the user sets the relevant drive again.

Das Kopfabschnitt 12 bleibt in jeder beliebigen Einstellung des Rückenabschnitts 13 in der jeweils maximal abgewinkelten Stellung gegenüber dem Rückenabschnitt 13. Die Figuren 2 und 3 veranschaulichen Zwischenstellungen mit unterschiedlichen Neigungswinkeln des Rückenabschnittts 13.The head portion 12 remains in any setting of the back portion 13 in the respective maximum angled position relative to the back portion 13. Die Figures 2 and 3 illustrate intermediate positions with different angles of inclination of the spine portion 13th

Wenn der betreffende Antrieb in der entgegengesetzten Richtung in Umdrehung versetzt wird, fährt das Hubrohr 37 wieder ein. Damit wird zunächst der Rückenabschnitt 13 soweit abgesenkt, bis es in die horizontale Lage zurückgekehrt ist. In der horizontalen Lage wird eine weitere Abwärtsbewegung durch das formschlüssige Zusammenwirken der Querstrebe 33 mit den Holmen 19 des Zwischenrahmens 18 begrenzt. Erst wenn diese Stellung erreicht ist, und somit von dem Zwischenhebel 44 keine Kraft mehr auf die Strebe 33 übertragen werden muss, beginnt sich der Zwischenhebel 44 gegenüber dem Rückenabschnitt 13 zu verschwenken. Diese Verschwenkung bedeutet, dass der Kopfabschnitt 12 ebenfalls abgesenkt wird.When the drive in question is rotated in the opposite direction, the lifting tube 37 retracts. Thus, first, the back portion 13 is lowered so far until it has returned to the horizontal position. In the horizontal position will be another downward movement limited by the positive cooperation of the transverse strut 33 with the bars 19 of the intermediate frame 18. Only when this position is reached, and thus no more force has to be transmitted to the strut 33 of the intermediate lever 44, the intermediate lever 44 begins to pivot relative to the back portion 13. This pivoting means that the head portion 12 is also lowered.

Ohne die Verwendung eines weiteren Elektroantriebs kann der Benutzer den Kopftabschnitt 12 ohne fremde Hilfe in eine ergonomisch angenehme Position bringen. Die praktische Erfahrung zeigt, dass in jeder beliebigen Sitzposition mit mehr oder weniger stark angehobenem Rückenabschnitt 13 immer die maximale Anhebung des Kopfabschnitts 12 erwünscht ist.Without the use of another electric drive, the user can bring the head section 12 into an ergonomically comfortable position without assistance. Practical experience shows that in any sitting position with more or less raised back portion 13 always the maximum lift of the head portion 12 is desired.

Der zwangsläufige Antrieb des Kopfteils sorgt außerdem für die richtige Reihenfolge und erspart zusätzlichen steuerungstechnischen Aufwand in der zentralen Steuerung des Bettes.The inevitable drive of the head part also ensures the correct order and saves additional control engineering effort in the central control of the bed.

Es ist unschwer zu erkennen, dass der Schwenkanschlag, gebildet durch die Anschlagfläche 50 und die Querstrebe 33 genauso gut im Bereich der Längsholme 39 des Kopfabschnitts 12 untergebracht werden kann. Der Vorteil der beschriebenen Anordnung besteht darin, dass bei Bedarf die Bewegung des Kopfteils durch Aushängen der Koppelstrebe 45 stillgesetzt werden kann, ohne dass am sonstigen Antrieb des Rückenteils irgendetwas verändert werden muss. Das Pflegepersonal kann also ohne weiteres das Bett in einen anderen Betriebsmodus umstellen, wenn dies bei speziellen Erkrankungen erforderlich wäre.It is easy to see that the pivot stop, formed by the stop surface 50 and the cross member 33 can just as well be accommodated in the region of the longitudinal members 39 of the head portion 12. The advantage of the arrangement described is that, if necessary, the movement of the head part can be stopped by unhooking the coupling strut 45 without having to change anything on the other drive of the back part. The nursing staff can thus easily change the bed to another mode of operation, if necessary for specific illnesses.

Ein Pflegebett weist einen Liegerahmen auf, der mit einem beweglichen Rückenteil und einem beweglichen Kopfteil versehen ist. Über eine Getriebeeinrichtung wird dafür gesorgt, dass mit einem einzigen Motor das Kopfteil und das Rückenteil bewegt werden. Das Anheben des Rückenteils beginnt zwangsläufig nachdem das Kopfteil die maximal angehobene Stellung erreicht hat.A nursing bed has a lying frame which is provided with a movable back part and a movable head part. A transmission device ensures that the head part and the back part are moved with a single motor. The lifting of the back part inevitably begins after the head part has reached the maximum raised position.
