Wie aus den Figuren ferner zu ersehen ist, sind in den Gelenken 6, 7 und 8 Drehwinkelgeber 13, 14, 15 und 16 vorgesehen. Der Drehwinkelgeber 13 erzeugt Winkelsignale, die proportional der Winkelstellung sind, welche die beiden Liegeflächenteilstücke 2 und 3 zueinander haben. Der Drehwinkelgeber 16 erzeugt Winkelsignale, die proportional den Winkelstellungen sind, die die beiden Liegeflächenteilstücke 4 und 5 zueinander haben. Im Gelenk 6 sind zwei Drehwinkelgeber 14 und 15 angeordnet. Der Drehwinkelgeber 14 erzeugt ein Winkelsignal, welches proportional zur Winkelstellung ist, die das Liegeflächenteilstück 3 gegenüber einer Bezugswinkellage (Null-Lage) einnimmt. Der Drehwinkelgeber 15 liefert ein Winkelsignal, welches proportional einem Winkel ist, den das Liegeflächenteilstück 4 gegenüber der Bezugswinkellage (Null-Lage) einnimmt. Die Bezugswinkellage kann durch ein ortsfestes Teil des Gelenkes 6 oder durch ein Konstruktionsteil der Tragsäule 18 bestimmt sein. In bevorzugter Weise handelt es sich um eine vertikale oder horizontale Bezugsebene. Der Winkelbezug kann konstruktiv, beispielsweise durch einen Gelenkbolzen 24, erreicht werden, welcher zur Bildung des Gelenks 6 fest mit der Tragsäule 18, insbesondere dem vertikal verschiebbaren Säulenmantel, verbunden ist, wie es beispielsweise aus der EP 0 406 462 B1 bekannt ist. Mit dem Gelenkbolzen können Rotore 25 und 26 der als Potentiometer ausgebildeten Drehwinkelgeber 14 und 15 drehfest verbunden sein. Die drehfeste Verbindung kann durch Schweißen, Formschluß oder in anderer geeigneter Weise mit dem Gelenkbolzen 24 erfolgen. Gehäuse 27 und 28 der Drehwinkelgeber, insbesondere Potentiometer, sind drehfest mit den beiden Liegeflächenteilstücken 3 und 4, beispielsweise über fest mit den Liegeflächenteilstücken verbundenen Scharnierstücke, welche zur Bildung des Gelenkes 6 zusammen mit dem Gelenkbolzen 24 dienen, verbunden. Durch die Relatiwerdrehung der Rotore 25 und 26 gegenüber den Gehäusen 27 und 28 läßt sich beim Verschwenken der Liegeflächenteilstücke 3 und 4 in bekannter Weise eine Verstellung von Abtastmitteln in den bevorzugt als Potentiometer ausgebildeten Drehwinkelgebern erreichen, wodurch den Schwenkwinkeln proportionale elektrische Winkelsignale erzeugt werden. Da der Gelenkbolzen 24 fest mit der Tragsäule 18 verbunden ist, läßt sich eine Bezugswinkelposition (Null-Lage) definieren, bezüglich welcher die Verdrehung bzw. Verschwenkung der Liegeflächenteilstücke 3 und 4 bestimmt wird.As can also be seen from the figures, 6, 7 and 8 are rotary angle sensors in the joints 13, 14, 15 and 16 are provided. The rotary encoder 13 generates angle signals, which are proportional to the angular position which the two lying surface sections 2 and Have 3 to each other. The rotary encoder 16 generates angle signals that are proportional are the angular positions that the two lying surface sections 4 and 5 to each other to have. In the joint 6, two rotary angle sensors 14 and 15 are arranged. The rotary encoder 14 generates an angle signal that is proportional to the angular position that the Lying surface section 3 occupies a reference angular position (zero position). The Angle of rotation encoder 15 supplies an angle signal which is proportional to an angle occupies the lying surface section 4 with respect to the reference angular position (zero position). The The reference angular position can be determined by a fixed part of the joint 6 or by a construction part the support column 18 to be determined. It is preferably a vertical or horizontal reference plane. The angle reference can be constructive, for example by a hinge pin 24, which is used to form the Joint 6 fixed to the support column 18, in particular the vertically displaceable column casing, is connected, as is known for example from EP 0 406 462 B1. With the hinge pin rotors 25 and 26 can be designed as potentiometers Angle of rotation encoder 14 and 15 are connected in a rotationally fixed manner. The non-rotatable connection can by welding, positive locking or in another suitable way with the hinge pin 24 take place. Housing 27 and 28 of the rotary encoder, in particular potentiometers, are non-rotatably with the two lying surface sections 3 and 4, for example with fixed the lying surface sections connected hinge pieces, which form the joint 6 serve together with the hinge pin 24, connected. By the relative rotation the rotors 25 and 26 relative to the housings 27 and 28 can be pivoted the lying surface sections 3 and 4 in a known manner an adjustment of Reach scanning means in the rotary angle sensors, which are preferably designed as potentiometers, thereby generating electrical angle signals proportional to the swivel angles become. Since the hinge pin 24 is firmly connected to the support column 18, one can Define the reference angle position (zero position) with respect to which the rotation or Pivoting the lying surface sections 3 and 4 is determined.

Auch für die Drehwinkelgeber 13 und 16 kann eine Anordnung, wie sie in der Fig. 3 gezeigt ist, gewählt werden. Dabei ist das Gehäuse 27 bzw. 28 des Drehwinkelgebers drehfest mit einem der beiden Liegeflächenteilstücken 2 oder 3 bzw. 4 oder 5 verbunden, und der Rotor 25 bzw. 26 ist mit einem beispielsweise bolzenförmigen Konstruktionselement, welches zur Gelenkbildung dient und drehfest mit dem anderen Liegeflächenteilstück verbunden ist, drehfest verbunden. Auf diese Weise erreicht man ebenfalls Winkelsignale, die proportional einem Winkel sind, den die beiden Liegeflächenteilstücke 2 und 3 bzw. 4 und 5 zueinander einschließen. Da über die beiden mittleren Liegeflächenteilstücke 3 und 4 die Winkelstellung zu einer Bezugswinkellage (Null-Lage) durch die Drehwinkelgeber 14 und 15 bestimmt wird, ist eine definierte Positionierung auch der beiden äußeren Liegeflächenteilstücke 2 und 5 gewährleistet.An arrangement as shown in FIG. 3 can also be used for the rotary angle sensors 13 and 16 is selected. The housing 27 or 28 of the rotary angle encoder non-rotatably connected to one of the two lying surface sections 2 or 3 or 4 or 5, and the rotor 25 or 26 is, for example, a bolt-shaped construction element, which is used to form joints and rotatably with the other lying surface section is connected, non-rotatably connected. In this way you can also be reached Angle signals that are proportional to an angle that the two lying surface sections Include 2 and 3 or 4 and 5 to each other. Because over the two middle lying surface sections 3 and 4 the angular position to a reference angular position (zero position) the angle of rotation encoder 14 and 15 is determined, a defined positioning is also the two outer lying surface sections 2 and 5 guaranteed.

Die von den Drehwinkelgebem 13, 14, 15 und 16 erzeugten Winkelsignale können in zweierlei Hinsicht ausgewertet werden. Wie aus der Fig. 2 zu ersehen ist, sind die Drehwinkelgeber 13 bis 16 mit einer Speichereinrichtung 19 verbunden. Hierdurch läßt sich erreichen, daß Winkelstellungen der Liegeflächenteilstücke, die sich als besonders vorteilhaft bei einer bestimmten Behandlungsart an einem Patienten erwiesen haben, in der Speichereinrichtung 19 gespeichert werden können. Für spätere Behandlungen dieser Art am Patienten oder auch an anderen Patienten mit im wesentlichen gleichen Körpermaßen und Krankheitssymptomen können dann diese eingespeicherten Positionen der Liegeflächenteile abgerufen werden zur Aktivierung der Steuereinrichtung 17, welche mit der Speichereinrichtung 19 verbunden ist. Die Steuereinrichtung 17 steuert dann die jeweiligen Arbeitszylinder 9 bis 12 so, daß diese die Liegeflächenteilstücke in die gewünschten Positionen bringen. Wie aus der Fig. 2 ferner zu ersehen ist, ist eine Vergleichseinrichtung 22 vorgesehen, welche mit den jeweiligen Drehwinkelgebern 13, 14, 15 und 16 verbunden ist. Femer ist die Vergleichereinrichtung 22 mit der Speichereinrichtung 19 verbunden. Durch Vergleich der in der Speichereinrichtung 19 gespeicherten Winkelpositionen mit den von den Drehwinkelgebem 13 bis 16 gelieferten Winkelsignalen erfolgt eine Überwachung des jeweiligen Stellvorganges, der von den Arbeitszylindem 9 bis 12 an den Liegeflächenteilstücken 2 bis 5 durchgeführt wird, bis die gewünschte Winkelpositionierung zwischen den einzelnen Liegeflächenteilstücken erreicht ist. Die Vergleichereinrichtung 22 liefert dann an die Steuereinrichtung 17 ein entsprechendes Signal, welches angibt, daß die Liegeflächenteilstücke in den gespeicherten Winkelpositionen sich befinden. Wie die Fig. 2 zeigt, ist die Vergleichereinrichtung 22 mit der Steuereinrichtung 17 verbunden.The angle signals generated by the rotary angle sensors 13, 14, 15 and 16 can be in be evaluated in two ways. As can be seen from Fig. 2, the Angle of rotation encoder 13 to 16 connected to a storage device 19. This leaves achieve that angular positions of the lying surface sections, which prove to be special have proven to be advantageous for a certain type of treatment on a patient, in the storage device 19 can be stored. For later treatments of this Kind on the patient or also on other patients with essentially the same body dimensions and disease symptoms can then be stored in these positions of the lying surface parts are called up to activate the control device 17, which is connected to the storage device 19. The control device 17 then controls the respective working cylinders 9 to 12 so that these the lying surface sections in the bring desired positions. As can also be seen from FIG. 2, there is a comparison device 22 is provided, which with the respective angle of rotation sensors 13, 14, 15 and 16 is connected. The comparator device 22 with the memory device is furthermore 19 connected. By comparing those stored in the memory device 19 Angular positions with the angle signals supplied by the rotary angle sensors 13 to 16 the respective adjustment process is monitored by the working cylinders 9 to 12 is carried out on the lying surface sections 2 to 5 until the desired Angular positioning between the individual lying surface sections reached is. The comparator device 22 then delivers a corresponding one to the control device 17 Signal that indicates that the lying surface sections in the stored Angular positions are. As FIG. 2 shows, the comparator device 22 is included connected to the control device 17.

Die Speichereinrichtung 19 kann eine Aufnahmeeinrichtung für auswechselbare Speicher, beispielsweise in Form von Magnetkarten bzw. Magnetstreifen aufweisen, die patientenbezogen und/oder bezogen auf die Behandlungsart die entsprechenden Winkelstellungen der Liegeflächenteilstücke 2 bis 5 aufweisen. Es ist jedoch auch möglich, in einem zentralen Speicher an entsprechenden Speicherplätzen die Winkelpositionsdaten zu speichern, so daß sie bei Bedarf für die gesteuerte Betätigung der Arbeitszylinder 9 bis 12 abgerufen werden können.The storage device 19 can be a receiving device for exchangeable memories, for example in the form of magnetic cards or magnetic strips that are patient-related and / or the corresponding angular positions based on the type of treatment the lying surface sections have 2 to 5. However, it is also possible to the central position data in corresponding storage locations to save so that they can be used for the controlled actuation of the working cylinder 9th can be called up to 12.

Die gesteuerte Beaufschlagung der Arbeitszylinder 9 bis 12 mit einem Druckmittel, insbesondere Hydraulikflüssigkeit (Hydrauliköl) kann in der Weise erfolgen, wie es in Fig. 2 dargestellt ist. Hierbei sind die einzelnen Arbeitszylinder 9 bis 12 über zugeordnete von der Steuereinrichtung 17 ansteuerbare Ventile 29, 30, 31 und 32 mit einer gemeinsamen Druckmittelquelle 33 verbunden. Die Druckmittelquelle kann ein Druckmittelreservoir für die Hydraulikflüssigkeit und eine Pumpe zur Erzeugung des erforderlichen Arbeitsdrukkes aufweisen. Die Arbeitszylinder sind in bevorzugter Weise als einfach wirkende Zylinder ausgebildet. Wenn die jeweiligen Arbeitszylinder in ihren Arbeitsräumen mit dem Druckmittel versorgt sind, werden die damit verbundenen Liegeflächenteilstücke 2 bis 5 in die gewünschten Winkelpositionen gebracht. Das Zurückbringen der Arbeitszylinder in ihre Ausgangsstellung kann durch Schwerkraftwirkung erfolgen, wenn die Druckbeaufschlagung in den Arbeitsräumen der Zylinder abgeschaltet ist. Für die Druckmittelbeaufschlagung der Arbeitszylinder werden die zugeordneten Ventile 29 bis 32 von der Steuereinrichtung 17 angesteuert. Zur Betätigung der Pumpe der Druckmittelquelle 33 kann diese ebenfalls mit der Steuereinrichtung 17 verbunden sein. Bei gleichzeitiger Druckbeaufschlagung der Arbeitszylinder 9 bis 12 über die geöffneten Ventile 29 bis 32 mit dem von der gemeinsamen Druckmittelquelle 33 gelieferten Druckmittel erfolgt in den Arbeitsräumen der Arbeitszylinder ein Druckmittelausgleich, insbesondere dann, wenn auf der Auflagefläche ein Patient während des Bewegens der Liegeflächenteilstücke in ihre Sollpositionen liegt. Das von Patienten ausgeübte Gewicht wirkt der Kraft des Druckmittels entgegen, so daß eine harmonische Verstellgeschwindigkeit der einzelnen Liegeflächenteilstücke in ihre gewünschten Winkelpositionen stattfindet. In bevorzugter Weise erfolgt hierzu die Beaufschlagung der Arbeitszylinder 9 bis 12 gleichzeitig durch gleichzeitiges Öffnen der Ventile 29 bis 32 mit dem von der Druckmittelquelle 33 gelieferten Druckmittel.The controlled loading of the working cylinders 9 to 12 with a pressure medium, in particular Hydraulic fluid (hydraulic oil) can take place in the manner shown in FIG. 2 is shown. Here, the individual working cylinders 9 to 12 are assigned by the control device 17 controllable valves 29, 30, 31 and 32 with a common Pressure medium source 33 connected. The pressure medium source can be a pressure medium reservoir for the hydraulic fluid and a pump to generate the required working pressure exhibit. The working cylinders are preferably single-acting cylinders educated. If the respective working cylinders in their work rooms with the Pressure medium are supplied, the lying surface sections 2 to 5 connected with it brought into the desired angular positions. Returning the working cylinders in their initial position can be due to the action of gravity when pressurized in the workrooms the cylinder is switched off. For pressurization the working cylinder, the assigned valves 29 to 32 by the control device 17 controlled. To actuate the pump of the pressure medium source 33 can these are also connected to the control device 17. With simultaneous pressurization the working cylinder 9 to 12 via the open valves 29 to 32 with the Pressure medium supplied by the common pressure medium source 33 takes place in the work rooms the working cylinder pressure compensation, especially if on the A patient's support surface while moving the lying surface sections into their desired positions lies. The weight exerted by patients acts on the force of the pressure medium counter, so that a harmonious adjustment speed of the individual lying surface sections takes place in their desired angular positions. In a preferred manner for this purpose the application of the working cylinders 9 to 12 simultaneously by simultaneous Opening the valves 29 to 32 with the pressure medium supplied by the pressure medium source 33.
