Description

Die Erfindung betrifft ein Bett, bei dem es sich insbesondere um ein Kranken- oder ein Pflegebett handelt.The invention relates to a bed, which is in particular a hospital or a nursing bed.

Für insbesondere ältere und pflegebedürftige sowie kranke Personen existieren Pflege- und Krankenhausbetten, die über höhenverstellbare Untergestelle und verstellbare Matratzenauflagen verfügen. Diese Betten gewähren den Personen bzw. Patienten sowie dem Krankenhaus- bzw. Pflegepersonal ein Höchstmaß an Komfort.There are nursing and hospital beds for elderly and dependent persons as well as sick people, which have height-adjustable underframes and adjustable mattress pads. These beds provide the maximum comfort for the people or patients as well as the hospital or nursing staff.

Je nach dem Grad der Immobilität der ein derartiges Bett nutzenden Person kann es dennoch mühselig sein, ohne Hilfe aus dem Bett aufzustehen. Denn die Person muss sich zunächst in eine Position bewegen, in der sie mit dem Gesäß und gegebenenfalls den Oberschenkeln auf dem seitlichen Bettrand sitzt, um dann aufstehen zu können.However, depending on the degree of immobility of the person using such a bed, it can be cumbersome to get out of bed without help. Because the person must first move to a position in which she sits with the buttocks and possibly the thighs on the side edge of the bed to then get up.

Zur Erleichterung des Aufstehens aus einem Bett ist es aus JP-A-2000042053 und US-A-2004/0226093 bekannt, das Rückenteil und das Sitzflächenteil der Matratzenauflagevorrichtung relativ zum Unterschenkelteil der Matratzenauflagevorrichtung seitlich zu verschieben, und zwar über wahlweise eines der beiden Seitenteile des Bettrahmens hinaus. Im seitlich herausbewegten Zustand von Rückenteil und Sitzflächenteil der Matratzenauflagevorrichtung bedarf es einer Abstützung des Sitzflächenteils bzw. einer seitlichen Abstützung des Untergestells oder Bettrahmens, um die Gefahr des seitlichen Kippens des Betts zu verhindern.To facilitate getting up from a bed it is off JP-A-2000042053 and US-A-2004/0226093 known to laterally displace the back portion and the seat portion of the mattress overlay relative to the lower leg portion of the mattress overlay, over either one of the two side portions of the bed frame. In the laterally moved-out state of the back part and the seat part of the mattress support device, it is necessary to support the seat surface part or a lateral support of the underframe or bed frame in order to prevent the risk of lateral tilting of the bed.

Aus WO-A-2008/087288 , WO-A-2008/090278 und WO-A-2008/087289 ist es ferner bekannt, das Unterschenkelteil der Matratzenauflagevorrichtung eines Betts gegenüber den Rücken- und Sitzflächenteilen der Matratzenauflagevorrichtung seitlich über den Bettrahmen hinaus zu verschieben. Ferner ist es aus den zuvor genannten Schriften sowie aus DE-A-288 612 und US-A-4 805 246 bekannt, das Unterschenkelteil der Matratzenauflagevorrichtung eines Betts um eine vertikale Achse gegenüber dem verbleibenden Teil des Betts seitlich zu verschwenken bzw. das Unterschenkelteil zweiteilig auszuführen, wobei beide Teile beidseitig der Mittellängsachse des Betts angeordnet sind und jeweils um eine Vertikalachse gelenkig mit dem übrigen Teil (kopfteilseitigen Bereich) des Betts verbunden sind.Out WO-A-2008/087288 . WO-A-2008/090278 and WO-A-2008/087289 It is also known to move the lower leg portion of the mattress support device of a bed relative to the back and seat parts of the mattress support device laterally beyond the bed frame addition. Furthermore, it is off the aforementioned writings as well DE-A-288 612 and US-A-4,805,246 Known to pivot the lower leg portion of the mattress support device of a bed laterally about a vertical axis relative to the remaining part of the bed or the lower leg part in two parts, both parts are arranged on both sides of the central longitudinal axis of the bed and each articulated about a vertical axis with the remaining part (headboard side Area) of the bed are connected.

Ferner ist es aus beispielsweise EP-B-0 744 934 bekannt, das Unterschenkelteil der Matratzenauflage eines Krankenhaus- bzw. Pflegebetts nach unten zu verschwenken, um, wie bei den zuvor genannten und beschriebenen begannten Betten, über das Fußende aus dem Bett aufstehen zu können.Further, it is for example EP-B-0 744 934 It is known to pivot the lower leg portion of the mattress overlay of a hospital bed to be able to stand out of the bed over the foot as in the previously mentioned and described beds.

Moderne Kranken- oder Pflegebetten verfügen über ein insbesondere höhenverstellbares Untergestell, an dem der Bettrahmen abgestützt ist und das im Regelfall vier Standbeine aufweist, welche auf dem Untergrund ruhen, Die kopfteilseitigen Standbeine bilden dabei das kopfteilseitige Ende des Untergestells, während die fußteilseitigen Standbeine das fußteilseitige Ende des Untergestells definieren, Diese in Längserstreckung des Betts liegenden Enden des Untergestells dürfen aus Sicherheitsgründen einen bestimmen maximalen Abstand zum Kopfteil bzw, Fußteil des Bettrahmens nicht überschreiten; denn andernfalls würde die Gefahr bestehen, dass das Bett bei vertikalen Belastungen auf das Kopf- bzw. Fußteil kippen kann. Das Unterschenkelteil der Matratzenauflagevorrichtung derartiger Betten weist im Regelfall eine derart große Erstreckung zwischen dem Fußteil des Bettrahmens und dem Sitzflächenteil der Matratzenauflagevorrichtung auf, dass die Verbindungsebene zwischen Unterschenkelteil und Sitzflächenteil oberhalb des Untergestells zwischen dessen beiden Enden angeordnet ist. Unterschenkelteile mit einer solchen Erstreckung in Längsrichtung des Betts sind komfortabel, um nämlich bei erwachsenen Personen unabhängig von der Größe der Person die gesamten Unterschenkel ab dem Kniegelenk durch das Unterschenkelteil stützen zu können.Modern hospital or nursing beds have a particular height adjustable base on which the bed frame is supported and which usually has four legs resting on the ground, the headboard side legs form the headboard side end of the base, while fußteilseitigen legs the fußteilseitige end For reasons of safety, these ends of the underframe, which lie in the longitudinal extent of the bed, must not exceed a certain maximum distance from the head part or foot part of the bed frame; otherwise there would be a risk that the bed could tip over onto the head or foot part when subjected to vertical loads. The lower leg part of the mattress support device of such beds usually has such a large extent between the foot part of the bed frame and the seat surface part of the mattress support device that the connection plane between the lower leg part and the seat surface part is arranged above the underframe between the two ends. Lower leg parts with such an extent in the longitudinal direction of the bed are comfortable, namely to be able to support in adults regardless of the size of the person, the entire lower leg from the knee joint through the lower leg part.

Wenn man nun bei dem zuvor beschriebenen bekannten Kranken- oder Pflegebett das Unterschenkelteil seitlich verschieben oder auf andere Art und Weise gegenüber dem übrigen Teil des Betts verschwenken, abnehmen o.dgl. würde, um der im Bett zu liegenden Person das Aufrichten aus dem Bett über das Fußende zu erleichtern, wären fußteilseitige Bereiche des Untergestells immer noch im Wege.If you move laterally in the previously described known hospital or nursing bed, the lower leg part or pivot in any other way with respect to the remaining part of the bed, lose weight or the like. In order to make it easier for the person lying in bed to get up from the bed over the foot, footrest side portions of the underframe would still be in the way.

Schließlich ist es aus JP 03 063329 U , EP-A-0 178 951 und WO-A-2005/027813 bekannt, bei einem Bett, das ein Fußteil aufweist, welches nicht nach oben über die Liegefläche aufragt, d.h. z.B. keine hochkant stehende Platte o.dgl. Rahmen bzw. Gestelle aufweist, die Matratzenauflagevorrichtung gegenüber dem Bettgestellt über das Fußende zu verschieben, bis der Unterschenkelteil der Matratzenauflagevorrichtung über das Fußende ragt und nach unten weist. In dieser Position kann das Rückenteil hochgestellt sowie das Sitzteil nach vorne geneigt werden, womit sich die Situation wie bei einem Sessel mit Aufstehhilfe ergibt.Finally it is over JP 03 063329 U . EP-A-0 178 951 and WO-A-2005/027813 known in a bed having a foot, which does not rise up above the lying surface, ie, for example, no upstanding plate or the like. Frame or frames, to move the mattress support device relative to the bed placed over the foot until the lower leg portion of the mattress support device protrudes over the foot and facing down. In this position, the backrest can be raised and tilted the seat part forward, which is the situation like a chair with stand-up help.

Aus EP-A-2 181 684 und WO-A-2010/060717 sind verschiedene Variationen eines Betts bekannt, bei dem sich das Fußende vom restlichen Teil des Betts entfernen lässt, um bei wegbewegtem Fußende des Betts aus diesem bequem aussteigen bzw. sich auf das Bett setzen zu können.Out EP-A-2 181 684 and WO-A-2010/060717 Various variations of a bed are known in which the foot can be removed from the remaining part of the bed to get off the bed with wegbewegtem foot of this comfortable or to be able to sit on the bed.

FR 2909549 offenbart, ein Bett mit allen technischen Merkmalen des Oberbegriffs des Anspruchs 1. FR 2909549 discloses a bed with all the technical features of the preamble of claim 1.

Aufgabe der Erfindung ist es daher, ein Bett, insbesondere Kranken- oder Pflegebett zu schaffen, das sich auf einfache Art und Weise in eine Position verfahren lässt, in der das Aufrichten aus dem Bett und das Absetzen in das Bett über dessen Fußende bequem möglich ist.The object of the invention is therefore to provide a bed, in particular hospital or nursing bed, which can be moved in a simple manner in a position in which the raising from the bed and settling in the bed over the foot is easily possible ,

Zur Lösung dieser Aufgabe wird mit der Erfindung ein Bett vorgeschlagen, bei dem es sich insbesondere um ein Kranken- oder Pflegebett handelt und das versehen ist mit den Merkmalen des Anspruchs 1. Einzelne Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.To solve this problem, a bed is proposed with the invention, which is in particular a hospital or nursing bed and which is provided with the features of claim 1. Individual embodiments of the invention are the subject of the dependent claims.

Das erfindungsgemäße höhenverstellbare und trennbare Bett weist ein unterteiltes Untergestell auf, das wie der Bettrahmen und die Matratzenauflagevorrichtung längs einer sich parallel zu den Kopf- und Fußenden des Betts sowie quer zur Längserstreckung des Bett erstreckenden Unterteilungsebene unterteilbar bzw. unterteilt ist. Das gesamte Fußende des Betts, zu dem das fußendeseitige Teil der Matratzenauflagevorrichtung, das fußendeseitige Teil des Bettrahmens und das fußendeseitige Untergestellteil gehört, lässt sich vom Kopfende des Betts wegbewegen. Zum Kopfende des Betts gehören das kopfendeseitige Teil der Matratzenauflagevorrichtung, das kopfendeseitige Teil des Bettrahmens und das kopfendeseitige Untergestellteil.The height-adjustable and separable bed according to the invention comprises a subdivided sub-frame which, like the bed frame and the mattress support device, can be subdivided or subdivided along a subdivision plane extending parallel to the head and foot ends of the bed and transversely to the longitudinal extent of the bed. The entire foot of the bed, to which the foot-end-side part of the mattress-covering device, the foot-end-side part of the bed frame and the foot-end base part belongs, can be moved away from the head of the bed. The head of the bed includes the head end-side portion of the mattress overlay, the head-end portion of the bed frame, and the head-end base portion.

Beide Untergestellteile verfügen über selbsttätige und vorzugsweise synchron zueinander betätigbare Hubeinheiten, auf denen die fußendeseitigen Teile von Matratzenauflagevorrichtung und Bettrahmen einerseits bzw. die kopfendeseitigen Teile von Matratzenauflagevorrichtung und Bettrahmen andererseits ruhen. Im getrennten Zustand bedarf es also zur Abstützung der zuvor genannten fußendeseitigen und kopfendeseitigen Teile des Betts keinerlei weiterer Stützmaßnahmen. Das erfindungsgemäße Bett weist also insoweit selbsttätig und getrennt voneinander funktionsfähige höhenverstellbare Untergestellteile sowohl für das Fußende als auch für das Kopfende des Betts auf.Both underframe parts have automatic and preferably synchronously operable lifting units on which rest the Fußendeseitigen parts of mattress support device and bed frame on the one hand and the Kopfendeseitigen parts of mattress support device and bed frame on the other. In the separated state, therefore, it requires no further support measures to support the aforementioned foot-side and head-end parts of the bed. Thus, the bed according to the invention has, independently and separately from one another, functional height-adjustable underframe parts both for the foot end and for the head end of the bed.

Damit also lässt sich das Bett bequem teilen, indem das Fußende abgerückt werden kann und man damit über die "neu geschaffene" Ausstiegskante am unteren Ende des kopfteilseitigen Bettrahmenteils aus dem Bett aussteigen kann bzw. sich in das Bett niedersetzen kann.Thus, the bed can be easily divided by the foot can be moved off and you can get out of the bed so the "newly created" exit edge at the bottom of the headboard side bed frame part or can sit down in the bed.

Erfindungsgemäß ist ferner vorgesehen, dass die beiden Untergestellteile bei aneinander anliegenden koprendeseitigen und fußendeseitigen Teilen der Matratzenauflagevorrichtung sowie bei aneinander anliegenden fußendeseitigen und kopfendeseitigen Bettrahmenteilen elektrisch miteinander gekoppelt sind, und zwar durch eine lösbare Steckverbindung oder steckerlos, insbesondere drahtlos wie induktiv und/oder kapazitiv und/oder optisch gekoppelt sind. Beide Hubeinheiten sind motorisch angetrieben, benötigen also elektrische Energie für ihren Betrieb. Das Untergestell kann einen einzigen Spannungsversorgungsanschluss an einem seiner beiden Teile aufweisen, Die Energie für den nicht in diesem Teil untergebrachten Hubmechanismus wird dann dem jeweils anderen Untergestellteil über die Steckverbindung zugeführt. Alternativ ist es auch möglich, dass einer der beiden Untergestellteile über eine eigene autarke Energieversorgung in Form beispielsweise von Batterien bzw. wiederaufladbaren Elektrizitätsspeicher verfügt. Die Ansteuerung des autark mit Energie versorgten Untergestellteils kann dann über eine Kommunikationsverbindung zwischen beiden Untergestellteilen erfolgen, die automatisch hergestellt wird, wenn die beiden Untergestellteile aneinandergesetzt sind. Andere Ausgestaltungen für die Kommunikation und Energieversorgung beider Untergestellteile sind ebenfalls denkbar. So könnte man beispielsweise auch beide Untergestellteile und damit deren Hubeinheiten getrennt voneinander an das Spannungsversorgungsnetz anschließen, wozu beide Untergestellteile ein entsprechendes spannungsführendes Kabel aufweisen sollten.According to the invention it is further provided that the two underframe parts electrically adjacent to abutting koprendeseitigen and Fußendeseitigen parts of the mattress support device and adjacent foot-side and Kopfendeseitigen bed frame parts are coupled together, by a detachable plug connection or without a plug, in particular wirelessly such as inductive and / or capacitive and / or optically coupled. Both lifting units are motor-driven, so they need electrical energy for their operation. The subframe may have a single power supply terminal on one of its two parts. The power for the lifting mechanism not housed in this part is then supplied to the other subframe part via the plug connection. Alternatively, it is also possible that one of the two underframe parts has its own self-sufficient energy supply in the form of, for example, batteries or rechargeable electricity stores. The control of the autonomously supplied with power base part can then be done via a communication link between the two base parts, which is automatically prepared when the two base parts are juxtaposed. Other configurations for the communication and energy supply of both subframe parts are also conceivable. So you could, for example, both sub-frame parts and thus their lifting units separately connected to the power supply network, including both sub-frame parts should have a corresponding live cable.

In weiterer vorteilhafter Ausgestaltung der Erfindung ist vorgesehen, dass die kopfendeseitigen und fußendeseitigen Teile der Matratzenauflagevorrichtung und, sofern gewünscht, auch die kopfendeseitigen und fußendeseitigen Bettrahmenteile jeweils durch mindestens ein trennbares Verbindungselement mechanisch gekoppelt sind. Ferner kann bei dieser Variante, aber auch unabhängig von dieser Variante, vorgesehen sein, dass die kopfendeseitigen und fußendeseitigen Bettrahmenteile und, sofern gewünscht, auch die kopfendeseitigen und fußendeseitigen Teile der Matratzenauflagevorrichtung im miteinander mechanisch gekoppelten Zustand und/oder die kopfendeseitigen und fußendeseitigen Untergestellteile gegen unbeabsichtigte Abrückbewegungen in Längserstreckungsrichtung des Bettrahmens gesichert sind, und zwar insbesondere durch eine lösbare mechanische Verbindung gesichert sind. Die mechanische Kopplung der zuvor beschriebenen Bettrahmenteile bzw.

Fig. 1 zeigt ein Ausfuhrungsbeispiel eines erfindungsgemäßen Betts 10, das uber ein geteiltes Untergestell 12 einen geteilten Bettrahmen 14 und eine geteilte Matratzenauflagevorrichtung 16 verfügt. Das Bett 10 weist ein Fußende 18 und ein Kopfende 20 auf. Am Fußende 18 befindet sich ein Fußteil 22, während am Kopfende 20 ein Kopfteil 24 angeordnet ist. Fig. 1 shows an exemplary embodiment of a bed 10 according to the invention, a divided bed frame 12 a divided bed frame 14 and a divided Mattress topper 16 has. The bed 10 has a foot end 18 and a head end 20. At the foot end 18 is a foot part 22, while at the head end 20, a head part 24 is arranged.

Das Fußende 18 des Betts 10 umfasst ein fußendeseitiges Untergestellteil 26, ein fußendeseitiges Bettrahmenteil 28 sowie ein fußendeseitiges Matratzenauflageteil 30. Dementsprechend umfasst das Kopfende 20 des Betts 10 ein kopfendeseitiges Untergestellteil 32, ein kopfendeseitiges Bettrahmenteil 34 sowie ein kopfendeseitiges Matratzenauflageteil 36. Dieses Matratzenauflageteil 36 ist seinerseits unterteilt in ein verstellbares Rückenteil 38, ein feststehendes Sitzteil 40 und ein verstellbares Oberschenkelteil 42, wie dies an sich im Stand der Technik bekannt ist. Zum fußendeseitigen Teil 30 der Matratzenauflagevorrichtung 16 gehört ein Beinteil 44, das in diesem Ausführungsbeispiel als Unterschenkelteil ausgebildet ist, welches zweckmäßigerweise gelenkig mit dem Oberschenkelteil 42 verbunden ist, was bei 46 angedeutet ist. Die auf der Matratzenauflagevorrichtung 16 aufliegende Matratze umfasst ein kopfendeseitiges Matratzenteil 47 und ein fußendeseitiges Matratzenteil 48.The foot end 18 of the bed 10 comprises a foot-end base portion 26, a foot-side bed frame portion 28, and a foot-end mattress seat portion 30. Accordingly, the head end 20 of the bed 10 includes a head-end base portion 32, a bed-side bed frame portion 34, and a head-end mattress seat portion 36. This mattress base portion 36 is itself divided into an adjustable back part 38, a fixed seat part 40 and an adjustable thigh part 42, as is known per se in the prior art. To the foot end side part 30 of the mattress support device 16 includes a leg portion 44, which is formed in this embodiment as a lower leg part, which is advantageously hingedly connected to the upper leg portion 42, which is indicated at 46. The mattress resting on the mattress support device 16 comprises a head-end mattress part 47 and a foot-side mattress part 48.

Wie anhand der Fig. 1 zu erkennen ist, sind die zuvor genannten Teile beidseitig einer Unterteilungsebene 50 angeordnet. Durch Bewegen von Kopfende 20 bzw. Fußende 18 längs der Pfeile 51,52 lassen sich die beiden Enden des Betts 10 voneinander wegbewegen bzw. bei Bewegung in umgekehrter Richtung wieder zusammensetzen (siehe Fig. 5).As based on the Fig. 1 can be seen, the aforementioned parts are arranged on both sides of a subdivision plane 50. By moving the head end 20 or foot end 18 along the arrows 51, 52, the two ends of the bed 10 can be moved away from each other or put together again when moving in the opposite direction (see FIG Fig. 5 ).

Die Besonderheit des Betts 10 besteht in der Unterteilung des Untergestells 12 in die beiden Teile 26 und 32, die jeweils eine Hubeinheit 54,56 aufweisen, von denen jede das ihr zugeordnete Untergestellteil selbstständig stützt und gegebenenfalls auch bei getrenntem Bett selbstständig anheben und absenken könnte. Die Hubeinheit 56 des kopfendeseitigen Teils 32 des Untergestells 12 ist dabei Teil eines Gestells 58, das auf insgesamt vier Füßen 60,62 ruht und eine vordere sowie eine hintere Hubvorrichtung 64,66 aufweist. Die beiden dem Kopfteil 24 zugewandten Füße 60 tragen dabei die vordere Hubvorrichtung 64, während die hintere Hubvorrichtung 66 von den Füßen 62 getragen wird. Die Füße 60 bilden also das kopfendeseitige Ende 68 des Untergestells 12. Die zweite Hubeinheit 54 ist Teil des fußendeseitigen Untergestellteils 26 und wird von vier Fußen 70,72 getragen, die das fußendeseitige Ende 74 des Untergestells 12 bilden. Die fußendeseitige Hubeinheit 54 stutzt das fußendeseitige Bettrahmenteil 28 ab und weist eine vordere und eine hintere Hubvorrichtung 76,78 auf, die von den Füßen 70 bzw. 72 getragen werden.The peculiarity of the bed 10 consists in the subdivision of the undercarriage 12 in the two parts 26 and 32, each having a lifting unit 54,56, each of which independently supports the sub-frame part assigned to it and, if necessary, could raise and lower independently even with a separate bed. The lifting unit 56 of the head end-side part 32 of the undercarriage 12 is part of a frame 58 which rests on a total of four feet 60,62 and has a front and a rear lifting device 64,66. The two heads 60 facing the head part 60 carry the front lifting device 64, while the rear lifting device 66 is supported by the feet 62 becomes. The feet 60 thus form the head end-side end 68 of the undercarriage 12. The second lifting unit 54 is part of the Fußendeseitigen base part 26 and is supported by four feet 70,72, which form the Fußendeseitige end 74 of the undercarriage 12. The foot-end lifting unit 54 braces the foot-side bed frame member 28 and has front and rear elevators 76, 78 supported by the feet 70, 72, respectively.

Anhand von Fig. 2 ist erkennbar, wie die beiden Hubeinheiten 54,56 mit jeweils zwei Hubvorrichtung 64,66 bzw. 76,78 den Bettrahmen 14 anheben. Die beiden Bettrahmenteile 28,34 sind dabei mit Hilfe zweier Versteifungselemente 73 miteinander mechanisch gekoppelt, so dass der Bettrahmen 14 im angehobenen Zustand entlang der Unterteilungsebene 50 nicht zusammenfallen kann und auch unter Last stabil bleibt.Based on Fig. 2 can be seen how the two lifting units 54,56 with two lifting device 64,66 and 76,78 lift the bed frame 14. The two bed frame parts 28, 34 are mechanically coupled to one another with the aid of two stiffening elements 73, so that the bed frame 14 in the raised state along the dividing plane 50 can not collapse and remains stable under load.

Die Fign. 3 und 4 zeigen, dass das Bett gemäß diesem Ausführungsbeispiel wie ein herkömmliches Pflege- bzw. Krankenhausbett verschiedene Schrägstellungen und verschiedenen Höhenpositionen einnehmen kann, wie beispielsweise die Trendelenburg- oder die Anti-Trendelenburg-Position,The FIGS. 3 and 4 show that the bed according to this embodiment, like a conventional nursing bed, can assume different inclinations and different height positions, such as the Trendelenburg or the anti-Trendelenburg position,

Im vom Kopfende 20 des Betts 10 abgerückten Zustand des Fußendes 18, wie es in Fig. 5 gezeigt ist, kann man nun über die so geschaffene zum Fußende weisende Ausstiegskante 80 aus dem Bett aussteigen bzw. umgekehrt sich in dem Bett niederlassen (siehe wiederum Fig. 5).In the withdrawn from the head 20 of the bed 10 state of the foot end 18, as shown in Fig. 5 is shown, you can now get over the thus created foot-facing exit edge 80 from the bed or vice versa to settle in the bed (see again Fig. 5 ).

Wie in den Figuren angedeutet ist, sind die beiden Untergestellteile 26,32 elektrisch miteinander verbunden, um nämlich die beiden Hubeinheiten 54,56 automatisch betätigen zu können. Die Anordnung von Lauf- bzw. Lenkrollen 82 in den acht Fußen 60,62 und 70,72 des Untergestells 12 dienen der Verfahrbarkeit des Betts 10 bei dessen Normaleinsatz und der Verfahrbarkeit des Fußendes 18, wenn dieses vom Rest des Betts, nämlich vom Kopfteil 20 des Betts 10 abgerückt und wegbewegt wird.As indicated in the figures, the two subframe parts 26, 32 are electrically connected to one another, namely to be able to actuate the two lifting units 54, 56 automatically. The arrangement of running or castors 82 in the eight feet 60,62 and 70,72 of the base 12 serve the mobility of the bed 10 in its normal use and the mobility of the foot end 18, if this from the rest of the bed, namely from the head part 20th the bed 10 is moved away and moved away.

Die Hubeinheiten 54,56 des Untergestells 12 sind in diesem Ausführungsbeispiel als Hubkopftraversen mit z.B. Hydraulik- oder Spindelantrieben als Hubvorrichtungen ausgeführt. Als Hubeinheiten eignen sich auch Scherenhubmechanismen, wobei jedes Untergestellteil ein, zwei oder mehr Paare von Scherenhebeln umfassen kann.The lifting units 54,56 of the undercarriage 12 are in this embodiment as Hubkopftraversen with e.g. Hydraulic or spindle drives designed as lifting devices. Scissor lifting mechanisms are also suitable as lifting units, wherein each underframe part can comprise one, two or more pairs of scissor levers.
