Abstract

The invention provides a hospital bed with two driving motors that are used in the vertically adjustable jack in order to increase the hoisting power of the bed so as to be able to lift heavy patients. The two driving motors are mounted so as to mechanically operate in parallel. In order to obtain a symmetric load distribution among the two motors, the motors are electrically connected in series and are supplied from a joint voltage source as a serial connection.

Description

Pflegebett mit DoppelmotorantriebCare bed with double motor drive
In der DE 10 2004 019 144 ist ein Pflegebett beschrieben, das einen höhenverstellbaren Heber aufweist, der auf dem Matratzenrahmen angeordnet ist. Mit Hilfe des höhenver¬ stellbaren Hebers soll der Matratzenrahmen mit dem darauf liegenden Patienten aus der normalen Betthöhe in eine Pflegehöhe gebracht werden, die es dem Personal erleichtert, Handhabungen am pflegebedürftigen Patienten vorzunehmen.In DE 10 2004 019 144 a nursing bed is described, which has a height-adjustable lift, which is arranged on the mattress frame. With the help of höhenver ¬ adjustable lift the mattress frame to be placed on a care level with the patient lying on it from the normal bed height, making it easier for the staff to carry out manipulations on long-term care patients.
Zur Höheverstellung weist das bekannte Bett einen Elektromotor auf, der über ein Schneckengetriebe eine Schraubspindel antreibt. Die Schraubspindel erstreckt sich zwischen dem Heberfuß und dem Heberkopf, um den Heber entsprechend in der Höhe zu strecken. Der Antrieb ist selbsthemmend. Der Elektromotor selbst ist ein Kleinspannungs- gleichstrommotor. Die Versorgungsspannung liegt bei ca. 24 Volt Gleichspannung. Mit dem bekannten Bett können Patienten bis zu einem konstruktiv vorgegebenen maximalen Körpergewicht gehoben und gesenkt werden. Die konstruktive Grenze ergibt sich im Wesentlichen aus der Hubkraft des verwendeten Elektromotors .For height adjustment, the known bed has an electric motor which drives a screw via a worm gear. The jackscrew extends between the lifter base and the lifter head to extend the lifter accordingly in height. The drive is self-locking. The electric motor itself is a low voltage direct current motor. The supply voltage is approx. 24 volts DC. With the known bed patients can be raised and lowered up to a design maximum body weight. The constructive limit results essentially from the lifting force of the electric motor used.
Ausgehend hiervon ist es Aufgabe der Erfindung ein Pflegebett zu schaffen, das in der Lage ist, Patienten mit einem höheren Körpergewicht heben und senken zu können.Based on this, it is an object of the invention to provide a nursing bed, which is able to raise and lower patients with a higher body weight.
Das erfindungsgemäße Pflegebett weist einen höhenverstellbaren Heber auf. Zur Höhenverstellung des Sockels sind zwei Elektromotoren vorgesehen, die kinematisch parallel arbeiten. Da diese Elektromotoren aufgrund des Gewindespindelantriebs selbstblockierend sind, können, wenn keine Gegenmaßnahmen getroffen werden, Verspannungen auftreten, die das Bett und die Motoren beschädigen. Wegen der Steifheit der Hebelmechanik des Sockels genügen hierzu geringe Wegunterschiede der Elektromotoren.The nursing bed according to the invention has a height-adjustable lift. To adjust the height of the base two electric motors are provided, which work kinematically in parallel. Since these electric motors are self-locking due to the threaded spindle drive, if no countermeasures are taken, tensions can occur which damage the bed and the motors. Because of the stiffness of the lever mechanism of the base to meet this small path differences of the electric motors.
Um dem vorzubeugen sind bei dem erfindungsgemäßen Pflegebett die beiden Elektromotoren elektrisch in Reihe geschaltet .To prevent this, the two electric motors are electrically connected in series in the nursing bed according to the invention.
Aufgrund dieser schaltungstechnischen Anordnung wird dafür gesorgt, dass die mechanische Belastung der beiden Motoren selbsttätig symmetriert wird. Bei demjenigen Motor, bei dem die mechanische Belastung größer ist, tritt eine, wenn auch kleine, Drehzahlreduzierung auf. Hierdurch reduziert sich die Gegen-EMK bei diesem Motor, was dazu führt, dass die für den anderen Motor zur Verfügung stehende Antriebsspannung höher wird. Durch diese höhere Spannung kann sich bei dem weniger stark belasteten Motor die Drehzahl entsprechend erhöhen solange, bis beide Motoren gleich belastet sind.Due to this circuit arrangement, it is ensured that the mechanical load of the two motors is automatically balanced. In the engine in which the mechanical load is greater, occurs, albeit small, speed reduction. This reduces the back EMF in this motor, which results in the higher the drive voltage available for the other motor. Due to this higher voltage, the speed can be reduced in the less heavily loaded motor increase accordingly until both motors are loaded equally.
Die Erfahrung hat gezeigt, dass verblüffenderweise diese Symmetrierung auch möglich ist, wenn die beiden Motoren mechanisch sehr starr miteinander gekoppelt sind und die mechanische Arbeit über Schraubspindelgetriebe, die eigentlich praktisch selbsthemmend sind, abgegeben wird.Experience has shown that, surprisingly, this balancing is also possible when the two motors are mechanically very rigidly coupled together and the mechanical work on Schraubspindelgetriebe, which are actually practically self-locking, is delivered.
Durch die Symmetrierung auf elektrischer Seite wird dafür gesorgt, dass beide Motoren etwa dieselben mechanische Leistung abgeben, was gleichbedeutend ist, dass beide Motoren etwa dieselbe Kraft erzeugen um den Patienten zu heben. Insbesondere werden hierdurch andauernde Verspannungen vermieden, die auftreten, weil u.U. ein Motor dem anderen Motor vorauseilt. Der vorauseilende Motor wäre gezwungen den überwiegenden Teil das Patientengewicht ständig zu tragen.Electrical balancing ensures that both motors deliver approximately the same mechanical performance, which means that both motors produce approximately the same force to lift the patient. In particular, this permanent tension is avoided, which occur because u.U. one engine leads the other engine. The anticipatory engine would be forced to carry the majority of the patient's weight constantly.
Im Übrigen sind Weiterbildungen der Erfindung Gegenstand von Unteransprüchen.Incidentally, developments of the invention are the subject of subclaims.
Beim Durchlesen der Figurenbeschreibung wird dem Fachmann klar, dass eine Reihe von Abwandlungen möglich sind, die aus den jeweiligen Gegebenheiten erfolgen. Außerdem sind weitere Kombinationen denkbar, die in allen Permutationen nicht darstellbar sind, ohne den Umfang der Figurenbeschreibung unnötig zu erhöhen.When reading the figure description, it will be clear to the person skilled in the art that a number of modifications are possible, which take place from the respective circumstances. In addition, further combinations are conceivable that can not be represented in all permutations without unnecessarily increasing the scope of the description of the figures.

Figur 1 zeigt in einer perspektivischen Darstellung ein Pflegebett 1 in der Liegestellung, während Figur 2 das Pflegebett 1 in der Sitz- oder Sesselstellung wiedergibt.Figure 1 shows a perspective view of a nursing bed 1 in the lying position, while Figure 2 shows the nursing bed 1 in the seat or chair position.
Das Pflegebett 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 wie veranschaulicht im Abstand zum Boden, womit zwischen ünterkante der Seitenwand 5 und dem Boden ein Spalt besteht, der es dem Pflegepersonal ermöglicht, die Fußspitzen unter das Bett zustellen. Die Seitenwand 5 ist beweglich gelagert und gelangt in der Sesselstellung des Pflegebetts 1 in eine nach unten verschobene Position, wie dies Figur 2 erkennen lässt. Die spezielle Lagerung der Seitenwand 5 ist beispielsweise ausführlich in der DE 199 12 937 A 1 erläutert.The nursing bed 1 has a Bettumrandung 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 reclining position as illustrated at a distance from the ground, so there is a gap between ünterkante the side wall 5 and the bottom, which allows the nursing staff to deliver the toes under the bed. The side wall 5 is movably mounted and arrives in the chair position of the nursing bed 1 in a downwardly shifted position, as can be seen Figure 2. The special mounting of the side wall 5 is explained for example in detail in DE 199 12 937 A 1.
Innerhalb der Bettumrandung 2 befindet sich ein Bett- heber 7, wie es die Figur 3 erkennen lässt.Inside the bed surround 2 is a bed Lift 7, as it can be seen in Figure 3.
Zu dem Bettheber 7 gehören ein höhenverstellbarer Sockel 8, auf dessen Kopf ein Drehscharnier 9 mit einer vertikalen Drehachse befestigt ist, ein Zwischenrahmen 10, sowie ein Liegerahmen 11, auf dem sich eine Matratze 12 befindet. Der Liegerahmen 11 ist in der Draufsicht rechteckig.To the bed lifter 7 include a height-adjustable base 8, on the head of a rotary hinge 9 is fixed with a vertical axis of rotation, an intermediate frame 10, and a reclining frame 11, on which a mattress 12 is located. The reclining frame 11 is rectangular in plan view.

Der Unterschenkelabschnitt 16 ist an dem von dem Zentralabschnitt 13 abliegenden Ende des Oberschenkelabschnittes 15 anscharniert. Die Scharnierachsen, um die die Abschnitte 14, 15, 16 relativ zu dem Zentralabschnitt 13 beweglich sind, liegen horizontal. Schließlich gehört zu dem Liegerahmen 11. noch ein Fuß- abschnitt 17, der starr mit dem Sockel 8 unmittelbar verbunden ist.The reclining frame 11 is divided into a central portion .13, which is fixedly connected to the intermediate frame 10, a back portion 14 which is hinged to the central portion 13, a thigh portion 15, which is also hinged to the central portion 13, as well as a Lower leg section 16. The lower leg section 16 is hinged on the end remote from the central section 13 of the thigh section 15. The hinge axes about which the sections 14, 15, 16 are movable relative to the central section 13 are horizontal. Finally, the foot frame 11 still has a foot section 17, which is rigidly connected directly to the base 8.
Der Zentralabschnitt 13 des Liegerahmens 11 weist zwei parallel zueinander verlaufenden Längsholme 18 auf, die entsprechend der Breite des Pflegebetts 1 voneinander beabstandet sind. Wegen der seitlichen Ansicht verdeckt der sichtbare Längsholm 18 den dahinter liegenden zugehörigen Längsholm des Zentralabschnitts 13.The central portion 13 of the reclining frame 11 has two mutually parallel longitudinal bars 18, which are spaced apart according to the width of the nursing bed 1. Because of the lateral view, the visible longitudinal spar 18 conceals the associated longitudinal spar of the central section 13 lying behind it.
Der Rückenabschnitt 14 wird von einem Holm 19 sowie einem weiteren dazu parallelen Holm begrenzt, der- wegen der Darstellung in Figur 3 nicht zu erkennen ist.

Zu dem höhenverstellbaren Sockel 8 gehören ein oberer Rahmen 39 sowie ein unter Rahmen 41, die aus entsprechend mit einander verschweißten Vierkantrohren bestehen, von denen zwei zueinander parallele Vierkantrohre Längsholme 39a bzw 41a bilden. Über insgesamt vier Kniehebelpaare 42 und 43 stützt sich der Oberrahmen 39 auf dem Unterrahmen 41 ab. Das Drehscharnier 9 ist mit dem Oberrahmen 39 verbunden.To the height-adjustable base 8 include an upper frame 39 and a frame 41, which consist of correspondingly welded together square tubes, of which two mutually parallel square tubes longitudinal bars 39a and 41a form. Over a total of four toggle lever pairs 42 and 43, the upper frame 39 is supported on the lower frame 41. The rotary hinge 9 is connected to the upper frame 39.
Die Kniehebelpaare 42, 43 befinden sich jeweils neben einer Längsseite des Sockels 8, so dass die damit korrespondierenden Kniehebelpaare 42, 43 an der anderen Längsseite in der Seitenansicht von Figur 3 nicht erkennbar sind.The toggle pairs 42, 43 are each located next to a longitudinal side of the base 8, so that the corresponding toggle pairs 42, 43 on the other longitudinal side in the side view of Figure 3 are not visible.
Das Kniehebelpaar 42, 43 setzt sich aus einem oberen Kniehebelarm 44 und einem unteren Kniehebel 45 zusammen. Jeder Kniehebel 42, 43 ist über ein Scharnier 46 mit hori- zontaler Achse auf der betreffenden Bettseite mit dem oberen bzw. unteren Rahmen 39, 41 gelenkig verbunden.

Each knee lever 42, 43 is connected via a hinge 46 with hori Zontaler axis articulated on the bed side in question with the upper and lower frame 39, 41. All axes of the hinges 46 are parallel to each other. The hinges 46 are coaxial with their axes to the axes of the hinges of the unrecognizable toggle 42, 43.

Die Achsen der Scharniere 47 sind zu den Achsen der Scharniere 46 parallel, wobei die Achsen von Scharnieren 46, 47, die auf den beiden Seiten einander entsprechen, zueinander koaxial sind.Hinges 47 connect the toggle pairs 42, 43 to the lower frame 41. The axes of the hinges 47 are parallel to the axes of the hinges 46, the axes of hinges 46, 47 corresponding to each other on both sides being coaxial with each other.
Die beiden Kniehebelpaare 42, 43 auf jeder Seite des Sockels 8 sind jeweils durch eine zugehörige horizontale Koppelstrebe 48 miteinander gekoppelt. Jede Koppelstrebe 48 ist wie gezeigt, mit dem Kniegelenk 49 jedes Kniehebelpaars 42, 43 scharnierartig verbunden.The two toggle pairs 42, 43 on each side of the base 8 are each coupled by an associated horizontal coupling strut 48 with each other. Each coupling strut 48 is, as shown, hingedly connected to the knee joint 49 of each toggle lever pair 42,43.
Schließlich verbindet auf jeder Seite des Sockels 8 eine schräg verlaufende Koppelstrebe 50 den oberen Kniehebelarm 44 des Kniehebelpaares 42 mit dem unteren Kniehebelarm 45 des Kniehebelpaares 43. Zumindest die miteinander fluchtenden Kniehebel 45 auf beiden Seiten des Bettes am Fußende sind durch eine Welle miteinander verbunden, von denen lediglich die Welle 51 in Fig. 4 zu erkennen ist. Das gleiche gilt für die beiden unteren Kniehebel 45 am Kopfende .Finally, connects on each side of the base 8, a sloping coupling bar 50, the upper toggle lever 44 of the toggle pair 42 with the lower toggle arm 45 of the toggle pair 43. At least the aligned knee lever 45 on both sides of the bed at the foot are connected by a shaft, from which only the shaft 51 can be seen in Fig. 4. The same applies to the two lower toggle 45 at the head end.
Zum Einstellen der Höhe des Hebers 8 sind gemäß Fig. /S zwei Spindelhubantriebe 52 und 53 vorgesehen. Zu dem Spindelhubantrieb 52 gehört ein permanent erregter Elektromotor 54a und ein in einem Getriebegehäuse 55a enthaltenes Schneckengetriebe. An das Getriebegehäuse 55a des Schneckenge- triebes schließt sich ein äußeres Teleskoprohr 5βa an, in dem längsverschieblich ein inneres Teleskoprohr 57a geführt ist. Das innere Teleskoprohr 57a wird in bekannter Weise mittels einer darin enthaltenen Schraubspindel hin und her bewegt .For adjusting the height of the lift 8 has two spindle lifting drives 52 and 53 are shown in FIG. / S provided. To the Spindelhubantrieb 52 includes a permanently energized electric motor 54a and a worm gear included in a transmission housing 55a. To the gear housing 55a of the worm gear drive is followed by an outer telescopic tube 5βa, in the longitudinally displaceable inner telescopic tube 57a is guided. The inner telescopic tube 57a is reciprocated in a known manner by means of a screw spindle contained therein.
Das innere Teleskoprohr 57a ist über eine Lasche 58 -an einer unteren Quertraverse 59 schwenkbar verankert. Die Quertraverse 59 erstreckt sich neben der Welle 51, d.h. neben den unteren Enden der beiden Kniehebelarme 45.The inner telescopic tube 57a is pivotally anchored via a lug 58 on a lower transverse beam 59. The cross-beam 59 extends adjacent to the shaft 51, i. next to the lower ends of the two toggle arms 45.
Neben dem Getriebegehäuse 55a ist in Verlängerung des inneren Teleskoprohrs 57a eine weitere Anschlussgabel 61a vorgesehen. Diese Anschlussgabel 61a ist auf einer Lasche 62 schwenkbar verankert. Die Lasche 62 sitzt an einer Quertraverse 63, die sich zwischen den Längsholmen 39a des oberen Heberrahmens 9 erstreckt.In addition to the gear housing 55a, a further connecting fork 61a is provided in extension of the inner telescopic tube 57a. This connecting fork 61a is pivotally anchored to a tab 62. The tab 62 is seated on a cross-beam 63 which extends between the longitudinal beams 39a of the upper lifter frame 9.
Der Spindelhubantrieb 53 liegt zu dem Spindelhubantrieb 52 mechanisch parallel und ist aus denselben Bauelementen aufgebaut, weshalb die dort auftretenden Konstruk- tions- und Strukturelemente mit demselben Bezugszeichen und dem Zusatz b versehen sind. Der Spindelhubantrieb 53 erstreckt sich zwischen Laschen 64 und 65, die an der unteren Traverse 59 bzw. der oberen Traverse 63 vorgesehen sind.The Spindelhubantrieb 53 is mechanically parallel to the Spindelhubantrieb 52 and is composed of the same components, which is why the construction and structural elements occurring there are provided with the same reference numeral and the addition b. The Spindelhubantrieb 53 extends between tabs 64 and 65, which are provided on the lower cross member 59 and the upper cross member 63.
Es ist unschwer anhand der Fig. 4 zu erkennen, dass jegliche Ungleichmäßigkeit im Hub der beiden Spindelhubantriebe 52 und 53 zu einer Verspannung in dem Heber 8 führt, mit der Konsequenz, dass lediglich der vorauseilende Motor beim Heben die Last übernehmen würde. Es besteht insoweit eine große Gefahr, diesen Motor mechanisch zu überlastet und seine Getriebeteile zu zerstören. Um die beiden Spindelhubantriebe miteinander zu synchronisieren, ist eine Schaltungsanordnung gemäß Fig. 5 vorgesehen.It can easily be seen from FIG. 4 that any unevenness in the stroke of the two screw spindle drives 52 and 53 leads to a tension in the lift 8, with the consequence that only the anticipatory motor would take over the load when lifting. There is a great danger so far, this engine mechanically overloaded and destroy its gear parts. In order to synchronize the two Spindelhubantriebe together, a circuit arrangement according to FIG. 5 is provided.
Bei den Elektromotoren 54a und 54b und der beiden Spindelhubantriebe 52 und 53 handelt es sich um permanent erregte Gleichstrommotoren. Ihre Stromversorgung geschieht über zwei zweipolige Anschlusskabel ββa und 66b. Somit gehören zu dem Spindelhubantrieb 52 zwei elektrische Anschlüsse 67a und 68a und zu dem anderen Spindelhubantrieb 53 die elektrischen Anschlüsse 67b und 68b.The electric motors 54a and 54b and the two Spindelhubantriebe 52 and 53 are permanently excited DC motors. Their power is supplied by two two-pole connection cables ββa and 66b. Thus, two electrical connections 67a and 68a belong to the spindle lifting drive 52 and the electrical connections 67b and 68b to the other spindle lifting drive 53.
Die beiden Elektromotoren 54a und 54b sind elektrisch in Serie geschaltet, d.h. der Motorstromeingang 68a ist mit dem Motorstromeingang 67b verbunden. Der Motorstromeingang 67a führt zu einem beweglichen Kontakt eines Tastschalters 69, während der Stromeingang 68b mit einem beweglichen Kontakt eines weiteren Tastschalters 70 verbunden ist. Deren Ruhekontakte 71 und 72 liegen gemeinsam an einem Anschluss 73 einer' Spannungs- oder Stromquelle 74.The two electric motors 54a and 54b are electrically connected in series, that is, the motor current input 68a is connected to the motor current input 67b. The motor current input 67a leads to a movable contact of a key switch 69, while the power input 68b is connected to a movable contact of another key switch 70. The normally closed contacts 71 and 72 are connected in common to a terminal 73 of a "voltage or current source 74th
Die beiden Tastschalter 69 und 70 weisen außerdem Arbeitskontakte 75 und 76 auf, die ebenfalls galvanisch miteinander verbunden sind und an einem zweiten Anschluss 77 der Spannungsquelle 74 liegen.The two key switches 69 and 70 also have working contacts 75 and 76, which are also galvanically connected to each other and are connected to a second terminal 77 of the voltage source 74.
Die gezeigte Stellung ist die Ruhestellung der beiden Tastschalter 69, 70 und führt dazu, dass die beiden Elektromotoren 54a und 54b der Spindelhubantriebe 52, 53 stromlos sind.The position shown is the rest position of the two key switches 69, 70 and causes the two electric motors 54a and 54b of the Spindelhubantriebe 52, 53 are de-energized.
Wenn der Tastschalter 69 betätigt wird; liegt der Stromeingang 67a der Serienschaltung der beiden Elektro- motoren 54a und 54b ah dem Anschluss 77 der Gleichspannungsquelle 74, während er andere Stromanschluss 68b mit dem Anschluss 73 verbunden ist. Dadurch werden die beiden Spindelhubantriebe 52, 53 beispielsweise im Sinne des Aus- fahrens bzw. Streckens des Hebers 8, also gleichsinnig, in Gang gesetzt.When the key switch 69 is operated; is the current input 67a of the series connection of the two electric motors 54a and 54b to the terminal 77 of the DC power source 74, while other power terminal 68b is connected to the terminal 73. As a result, the two spindle lifting drives 52, 53 are set in motion, for example in the sense of extending or extending the lifter 8, ie in the same direction.
Durch Loslassen und Betätigen des anderen Tastschalters 70 wird der Stromeingang 68b mit dem Anschluss 77 in der Spannungsquelle 74 verbunden, während der Stromeingang 67a der Serienschaltung der beiden Spindelhubantriebe 52 und 53 an dem Anschluss 77 der Spannungsquelle 74 angeschlossen bleibt. Auf diese Weise kann die Serienschaltung der beiden Spindelhubantriebe 52, 53 beispielsweise im Sinne des Einfahrens des Hebers 8 in Gang gesetzt werden.By releasing and pressing the other key switch 70, the power input 68b is connected to the terminal 77 in the voltage source 74, while the current input 67a of the series connection of the two Spindelhubantriebe 52 and 53 remains connected to the terminal 77 of the voltage source 74. In this way, the series connection of the two Spindelhubantriebe 52, 53 are set, for example, in the sense of retraction of the lifter 8 in motion.
Aufgrund der gezeigten Schaltung erfolgt eine selbsttätige Symmetrierung der Lastverteilung zwischen den beiden Spindelhubantrieben 52 und 53.Due to the circuit shown, an automatic balancing of the load distribution between the two Spindelhubantrieben 52 and 53.
Ohne Anspruch auf Vollständigkeit der Theorie der Wirkungsweise der Schaltung wird folgende Erklärung gegeben:Without any claim to completeness of the theory of the operation of the circuit, the following explanation is given:
Zur. Erläuterung des Sachverhalts sei angenommen, dass beim Betätigen beispielsweise des Tasters 69 im Sinne des Hebens der Spindelhubantrieb 52, in einer Stellung steht, in der er dem Spindelhubantrieb 53 vorauseilen würde. Eine solche Situation kann beispielsweise auftreten, wenn der Heber 8 aus der unteren mechanischen Endlage anfährt. Das Vorauseilen führt zunächst zu einer vergrößerten Lastübernahme verglichen mit dem Spindelhubantrieb 53. Aufgrund der höheren Belastung des Spindelhubantriebs 52 ist die Drehzahl des antreibenden zugehörigen Elektromotors 54a gering- fügig kleiner als die Drehzahl des anderen Elektromotors 54b. Dadurch ist die Gegen-EMK, die der Anker dieses Motors 54a erzeugt, kleiner als die Gegen-EMK des Ankers des Elektromotors 54b. Hierdurch kann der Strom durch die Seri- schaltung der Motoren steigen. Da aber der Motor 54a stärker belastet ist kann sich seine Drehzahl weniger schnell erhöhen als die des weniger belasteten Motors 54b. Somit kann der geringer belastete Elektromotor 54b wegmäßig aufholen. Er wird in der Beschleunigung erst gebremst, wenn seine Ausfahrstellung die des zunächst stärker belasteten Elekromotors 54a überholt.To. Explanation of the facts is assumed that when pressing, for example, the button 69 in terms of lifting the Spindelhubantrieb 52, in a position in which he would precede the Spindelhubantrieb 53. Such a situation may occur, for example, when the lifter 8 starts from the lower mechanical end position. The anticipation first leads to an increased load transfer compared to the spindle lifting drive 53. Due to the higher load on the screw lifting drive 52, the rotational speed of the driving associated electric motor 54a is low. gradually smaller than the speed of the other electric motor 54b. As a result, the back EMF generated by the armature of this motor 54a is smaller than the back EMF of the armature of the electric motor 54b. As a result, the current can rise through the series connection of the motors. However, since the motor 54a is more heavily loaded, its speed may increase less rapidly than that of the less loaded motor 54b. Thus, the lower loaded electric motor 54b can catch up. It is slowed down in the acceleration only when its extended position overtakes that of the initially more heavily loaded electric motor 54a.
Je nach der Elastizität, gegen die die beiden Spindelhubantriebe 52 und 53 arbeiten, wiederholt sich abwechselnd dieses Kompensationsspiel bis nach wenigen Wechseln, die Last zwischen den beiden Motoren 54a, 54b symmetrisch verteilt ist und beide in gleichem Maße Kraft erzeugen, um den Heber 8 zu strecken.Depending on the elasticity against which the two Spindelhubantriebe work 52 and 53, this compensation game is repeated alternately until after a few changes, the load between the two motors 54a, 54b is symmetrically distributed and both generate force to the same extent to the lifter 8 stretch.
Aufgrund der Schwungmasse der Anker der beiden Elektromotoren 54a und 54b tritt nach dem Erreichen der Gleichgewichtsbedingung ein gewisses Überschwingen auf, was die oben erwähnten Regelschwingungen hervorruft. Die Regelschwingungen klingen jedoch innerhalb kurzer Zeit nach wenigen Überschwingern ab.Due to the inertia of the armature of the two electric motors 54a and 54b occurs after reaching the equilibrium condition, a certain overshoot, which causes the above-mentioned control oscillations. However, the control vibrations stop within a short time after a few overshoots.
Damit das gewünschte Ziel erreicht werden kann, müssen, weil beide Motoren 54a, 54b dieselbe Kraft erzeugen sollen, zwangsläufig die Motoren 54a, 54b auch hinsichtlich der für die Krafterzeugung und Schwungmassen maßgeblichen Konstruktionsdetails weitgehend übereinstimmen. Die Drehrichtung hingegen spielt keine Rolle. Zweckmäßig ist es um eine maximale Auslastung zu erreichen, wenn die Nennspan- nung von jedem der beiden Spindelhubantriebe 52, 53 halb so groß ist wie die Ausgangsspannung der Stromquelle 74.In order for the desired goal to be achieved, since both motors 54a, 54b are to generate the same force, the motors 54a, 54b must also largely coincide with respect to the design details relevant to the force generation and flywheel masses. The direction of rotation, however, does not matter. It is expedient to achieve a maximum utilization if the nominal clamping tion of each of the two Spindelhubantriebe 52, 53 is half as large as the output voltage of the power source 74th
Die Erfindung ist in Verbindung mit einem drehbaren Pflegebett beschrieben. Es versteht sich jedoch, dass auf die Drehbarkeit auch verzichtet und die Erfindung auch auf ein normales Pflegebett angewendet werden kann.The invention is described in connection with a rotatable care bed. It is understood, however, that dispensed with the rotation and the invention can also be applied to a normal nursing bed.
Um die Hebefähigkeit eines Pflegebetts zu erhöhen und schwere Patienten heben zu können, werden im höhenverstellbaren Heber zwei Antriebsmotoren verwendet. Die beiden Antriebsmotoren sind mechanisch parallel wirkend eingebaut. Um eine symmetrische Lastverteilung zwischen den beiden Motoren zu erhalten, sind sie elektrisch in Reihe geschaltet und werden als Reihenschaltung aus einer gemeinsamen Spannungsquelle versorgt. To increase the lifting capacity of a nursing bed and to be able to lift heavy patients, two drive motors are used in the height-adjustable lift. The two drive motors are installed mechanically parallel. In order to obtain a symmetrical load distribution between the two motors, they are electrically connected in series and are supplied as a series connection from a common voltage source.
