Im Beispiel des zweiten Transportfahrzeugs wurde der lange Anschlag 15 der Andocktraverse 6 benutzt. Zum Detektieren der Belegung des Pflegebetts dient mindestens ein Drucksensor 23, wie er auch bei der Beschreibung des Personen - Transportstuhls 21 erwähnt wird. Weiter sind für den auf dem Pflegebett zu transportierenden Patienten 26 ein Pulsmesser 19 und Sensoren zur Erfassung des Hautwiderstands und ein Sender 20 mit einem Taster zur Aussendung eines Notsignals und einer Notaus - Schaltung vorgesehen. Weiter sind in der Fig.3 auch Sicherheits - Sensoren 22 auf der Vorderseite bezeichnet, die für die Scanschatten - Minimierung sorgen.
Am Fußende des Pflegebetts ist eine Sende - und Empfangseinheit für die Steuereinheit und das Sicherheitssystem des Pflegebetts angebracht. Eine Kamera 17 für die Gesichtsüberwachung sorgt für die Übermittlung der Gefühle des Patienten.Again Fig. 3 As can be seen, a first or front transport vehicle 29 and a second or rear transport vehicle 30 are connected by means of a care bed mount 27 for transporting a care bed. Here, the first transport vehicle has a cross member 28 on which acts as a docking cross member 6, as described in the description for Fig.1 and was shown on the second transport vehicle. The two laser scanners 2 are designated for the interconnection of the first and the second transport vehicle. In the example of the second transport vehicle, the long stop 15 of the docking traverse 6 was used. At least one pressure sensor 23 is used to detect the occupancy of the care bed, as it is also mentioned in the description of the personal transport chair 21. Furthermore, a heart rate monitor 19 and sensors for detecting the skin resistance and a transmitter 20 with a button for sending an emergency signal and an emergency off circuit are provided for the patient 26 to be transported on the care bed. Next are in the Fig. 3 also designates safety sensors 22 on the front side, which ensure that the scan shadow is minimized.

Fig.4 : zeigt eine räumliche Detailansicht der Kinematik eines Transportfahrzeugs. Diese Abbildung zeigt ein Transportfahrzeug ohne das umhüllende Fahrgestell 1. Auf Verbindungen zu dem Fahrgestell 1 wird an entsprechender Stelle hingewiesen. Zunächst wird die Kinematik der Antriebsräder erläutert. Im Vordergrund sind das, aus der Fig-1 bekannte linksseitige Antriebsrad 12 und eine Drehachse 43 zu erkennen, wobei diese Drehachse 43 mit dem Fahrgestell 1 verbunden ist und dort nicht bezeichnet ist.
Das Achslager 46 für das linksseitige Antriebsrad 12 mit seinem darüber liegenden Servomotor 45 ist mittels eines, nicht näher bezeichneten und nur von hinten zu sehenden, Winkelblech zu einer Funktionseinheit verbunden. In diesem Winkelblech läuft ein Zahnriemen über den der Servomotor 45 die Rotationsachse des linksseitigen Antriebsrads 12 antreibt. Auf der gegenüber liegenden Seite ist der entsprechende Servomotor 57 für den rechtsseitigen Antrieb zu erkennen. Auf dieser Seite ist das entsprechende Winkelblech von der Rückseite zu sehen. Hier ist der in diesem Winkelblech laufende entsprechende Zahnriemen 55 zu erkennen. Die gesamte Funktionseinheit besteht aus dem Antriebsrad 12 mit dem Achslager 46, dem Servomotor 45 und dem Winkelblech mit seinem Zahnriemen, ist über den Winkelhebel 42 über die Drehachse 43 schwenkbar. Der Winkelhebel 42 ist über das Gelenk 40 an einem U - förmigen Querlenker 34 befestigt, an dessen anderem Ende das entsprechende Antriebsrad entsprechend befestigt ist. An dem Gelenk 40 ist weiter ein Federelement 41 gelagert, dessen anderer Lagerungspunkt am Gehäuse befestigt ist. Auf der in der Fig.4 sichtbaren linken Seite des Transportfahrzeugs ist dieser Anlenkpunkt, bzw. Lagerungspnkt, als klötzchenförmige, kaum erkennbare, Lagerung gezeigt. Dagegen ist auf der gegenüber liegenden Seite dieser Punkt als Anlenkpunkt 56 des rechten Federelements bezeichnet. Das Federelement 41 dient dem Zweck, über den Winkelhebel 42 das Antriebsrad 12 auf die Bodenfläche zu drücken und somit den Bodenkontakt des Antriebsrads 12 zu verbessern. Entsprechendes gilt für das gegenüber liegende rechte Antriebsrad. Fig. 4 : shows a spatial detailed view of the kinematics of a transport vehicle. This figure shows a transport vehicle without the surrounding chassis 1. Connections to the chassis 1 are indicated at the appropriate point. First, the kinematics of the drive wheels will be explained. The left-hand drive wheel 12 known from FIG. 1 and an axis of rotation 43 can be seen in the foreground, this axis of rotation 43 being connected to the chassis 1 and not being designated there.
The axle bearing 46 for the left-hand drive wheel 12 with its servomotor 45 located above it is connected to form a functional unit by means of an angle plate, which is not designated in more detail and can only be seen from the rear. A toothed belt, via which the servomotor 45 drives the axis of rotation of the drive wheel 12 on the left, runs in this angle plate. The corresponding servomotor 57 for the right-hand drive can be seen on the opposite side. The corresponding angle plate can be seen from the rear on this side. Here is the in This angle plate running corresponding toothed belt 55 can be seen. The entire functional unit consists of the drive wheel 12 with the axle bearing 46, the servo motor 45 and the angle plate with its toothed belt and can be pivoted via the angle lever 42 over the axis of rotation 43. The angle lever 42 is fastened via the joint 40 to a U-shaped wishbone 34, at the other end of which the corresponding drive wheel is correspondingly fastened. A spring element 41 is also mounted on the joint 40, the other mounting point of which is attached to the housing. On the in the Fig. 4 This articulation point, or bearing point, is shown as a block-shaped, barely recognizable bearing on the left-hand side of the transport vehicle. In contrast, on the opposite side, this point is referred to as the articulation point 56 of the right spring element. The spring element 41 serves the purpose of pressing the drive wheel 12 onto the ground surface via the angle lever 42 and thus improving the ground contact of the drive wheel 12. The same applies to the opposite right drive wheel.

Eine weitere kinematische Einrichtung wird im Folgenden zum Anheben der Brückenplattform 11, bzw. des auf ihr lastenden Personen - Transportstuhls oder eines Teils eines Patientenbetts als Last, erläutert.
Um eine Last aufnehmen zu können ist es erforderlich, dass das Transportfahrzeug nach dem Darunterfahren unter die jeweilige Last diese anhebt und ihren Bodenkontakt löst um sie transportieren zu können.
Diesem Zweck dienen in direktem Kontakt die vorderen Hubstangen 53 und die hinteren Hubstangen 36.
Angehoben und abgesenkt werden die Hubstangen 53 und 36 mittels eines Stellelements 31, das mittels einer Gewindespindel über einen ein - und ausfahrbaren Zylinder über einen Gelenkkopf 52 und einen angelenkten Hubdreh - Hebel 51 die hierfür notwendigen Kräfte aufbringt.
Aus der Fig.4 . ist linksseitig deutlich zu erkennen wie der Hubdreh - Hebel 51 im Zusammenwirken mit dem jeweils vorderen Hubstangenhebel 49 mittels entsprechenden Drehbewegungen um eine Drehachse 48 die notwendigen Lageveränderungen der beiden vorderen Hubstangen 53 bewirkt.
Die vorderen Hubstangen 53 tragen jeweils die entsprechende vordere Trägerplatten - Aufhängung 54.Another kinematic device is explained in the following for lifting the bridge platform 11, or the person transport chair that weighs on it, or a part of a patient's bed as a load.
In order to be able to pick up a load, it is necessary that the transport vehicle lifts the respective load after driving underneath it and releases it from contact with the ground in order to be able to transport it.
The front lifting rods 53 and the rear lifting rods 36 serve this purpose in direct contact.
The lifting rods 53 and 36 are raised and lowered by means of an adjusting element 31, which applies the necessary forces by means of a threaded spindle via an extendable and retractable cylinder via a joint head 52 and an articulated rotary lift lever 51.
From the Fig. 4 . can clearly be seen on the left-hand side how the lifting and rotating lever 51, in cooperation with the respective front lifting rod lever 49, effects the necessary changes in the position of the two front lifting rods 53 by means of corresponding rotary movements about an axis of rotation 48.
The front lifting rods 53 each carry the corresponding front carrier plate suspension 54.

Gleichzeitig ist diesem Bereich der Fig.4 zu entnehmen, dass an dem Hubdreh-Hebel 51 eine Schubstange 47 angelenkt ist, die die Bewegungen des Hubdrehebels 51 über einen Achshebel 38 auf jeweils einem hinteren Schubstangenhebel 39 überträgt. Die Bewegungen der hinteren Schubstangenhebel 39 führen zu den notwendigen Lageveränderungen der beiden hinteren Hubstangen 36.
Die hinteren Hubstangen 36 tragen jeweils die entsprechende hintere Trägerplatten-Aufhängung 35.
Die Bewegung des Stellelements 31 erfolgt über einen Antrieb 32 und eine, die Kraft umleitende, Kraftübertragung 33. Die Kraftübertragung 33 ist mittels eines Gabelkopfes 44 am Querlenker 34 befestigt. Da der der Gabelkopf 44 drehbar am Querlenker 34 gelagert ist, kann sich der Querlenker 34, als Verbindungselement zwischen den beiden Winkelhebeln 42, bewegen, und so wird ermöglicht, dass die beiden Antriebsräder voneinander unabhängige, vertikale Schwenkbewegungen ausführen.
Die Stellelemente 50 für die vorderen Hubstangen 53 und die Stellelemente 37 für die hinteren Hubstangen 36 sind in der Fig.4 als geschwärzte Bereiche der entsprechenden Hubstangen gekennzeichnet.At the same time, this area is the Fig. 4 it can be seen that a push rod 47 is articulated on the lifting and rotating lever 51, which transfers the movements of the lifting and rotating lever 51 via an axle lever 38 to a respective rear push rod lever 39. The movements of the rear push rod levers 39 lead to the necessary changes in the position of the two rear lifting rods 36.
The rear lifting rods 36 each carry the corresponding rear carrier plate suspension 35.
The actuating element 31 is moved via a drive 32 and a force transmission 33 that diverts the force. The force transmission 33 is attached to the wishbone 34 by means of a fork head 44. Since the fork head 44 is rotatably mounted on the wishbone 34, the wishbone 34 can move as a connecting element between the two angle levers 42, and this enables the two drive wheels to perform vertical pivoting movements that are independent of one another.
The adjusting elements 50 for the front lifting rods 53 and the adjusting elements 37 for the rear lifting rods 36 are in the Fig. 4 marked as blackened areas of the corresponding lifting rods.

Insgesamt wird durch die aufgezeigte Anordnung der Hubstangen 36 und 53, die dazwischen liegende Hebelanordnung 38,47,49 ,51 und das Stellelement 31 in Zusammenwirkung mit dem Querlenker 34, sowie dessen Einwirken auf den Winkelhebel 42 erreicht, dass der Schwerpunkt der Last direkt im Bereich der Antriebsräder liegt.
Die Stützräder 8 haben deshalb im Wesentlichen eine stabilisierende Funktion. Es ist ein System zur Energieversorgung vorhanden, das entweder über induktive, im Boden verlegte, Leitungen, oder über stationär anfahrbare Energieversorgungs-Stationen für das Aufladen von Batterien versorgt wird.
Die Krankenbetten werden entweder in besonderen
Lagerräumen mir ihren Transportfahrzeugen gelagert oder sie lagern auf speziellen Lagergestellen die bezüglich der Höhe ihrer Unterlage ein Darunterfahren und Anheben mittels der Transportfahrzeuge ermöglichen.
Die Steuerung der mit den jeweiligen Transportfahrzeugen bestückten Krankenbetten oder Personentransportstühle erfolgt über eine, im jeweiligen Krankenhaus oder Pflegezentrum vorhandene, Steuerzentrale, die in sämtlichen zu befahrenden Gängen und Aufzügen einen wechselseitigen Funkkontakt mit allen Fahrzeugen auf einer besonderen Funkfrequenz ermöglicht.
Die Steuerung eines Krankenbetts erfolgt mittels einer besonderen Steuerung die die beiden am Transportvorgang beteiligte Fahrzeuge als eine Einheit betrachtet. Entscheidet die betreffende Steuerzentrale, dass ein Patient von einer Station A zu einer Station B zu befördern ist, fährt das Fahrzeug mit dem Patienten in dem betreffenden Krankenbett automatisch den vorgeschriebenen Weg. Hierbei entscheidet dann das jeweilige Pflegepersonal ob der Patient transportfähig ist und meldet den fertigen Transportzustand an die Steuerzentrale. Je nach dem Ausbauzustand des gesamten Transportsystems erfolgt dann der Transport entweder direkt aus dem Krankenzimmer oder von einer besonderen Anlaufstation der jeweiligen Krankenstation.Overall, the arrangement shown of the lifting rods 36 and 53, the lever arrangement 38,47,49, 51 in between and the actuating element 31 in cooperation with the wishbone 34 and its action on the angle lever 42 ensure that the center of gravity of the load is directly in the Area of the drive wheels.
The support wheels 8 therefore essentially have a stabilizing function. There is a system for energy supply that is supplied either via inductive lines laid in the ground or via stationary accessible energy supply stations for charging batteries.
The sick beds are either in special
Storage rooms with their transport vehicles or they are stored on special storage racks which, with regard to the height of their base, enable them to be driven underneath and lifted by means of the transport vehicles.
The control of the hospital beds or passenger transport chairs equipped with the respective transport vehicles takes place via one in the respective Hospital or care center, control center that enables two-way radio contact with all vehicles on a special radio frequency in all corridors and elevators to be used.
A hospital bed is controlled by means of a special control that considers the two vehicles involved in the transport process as one unit. If the relevant control center decides that a patient is to be transported from a station A to a station B, the vehicle automatically drives the prescribed route with the patient in the relevant hospital bed. The respective nursing staff then decides whether the patient is transportable and reports the completed transport status to the control center. Depending on the expansion status of the entire transport system, the transport takes place either directly from the hospital room or from a special contact point in the respective hospital ward.
