Description

Die Erfindung betrifft ein Fahrgestell für eine drehbare Patientenplattform. Die Patientenplattform kann insbesondere eine Patientenaufstehhilfe, einen Patientenlifter oder einen Stehtrainer tragen.The invention relates to a chassis for a rotatable patient platform. The patient platform may, in particular, carry a patient lift-up aid, a patient lift or a standing coach.

Stand der TechnikState of the art

Fahrbare Gestelle für drehbare Patientenplattformen mit darauf angebrachten Aufstehhilfen, Patientenliftern und Stehtrainern in unterschiedlichsten Ausführungen sind seit langem bekannt.Mobile racks for rotatable patient platforms with stand-up aids, patient lifts and standing trainers in various designs have long been known.

Die DE 196 47 498 A1 beschreibt eine Vorrichtung zum Aufrichten von Patienten aus einer sitzenden in eine aufrechte Position. Diese weist einen Rahmen auf, der aus vier rechtwinklig zueinander angeordneten hohlprofilförmigen Streben besteht, wobei die kürzer ausgebildeten Streben zwischen den länger ausgebildeten Streben angeordnet sind. Der Rahmen umgibt eine Grundplatte. Zwischen der Grundplatte und einer Fußstütze sind gleichmäßig über den Umfang verteilt Stützrollen angeordnet. Diese dienen der Aufnahme der Patientengewichtskraft und der Drehermöglichung des Patienten. Der Nachteil dieser Konstruktion besteht darin, dass eine große Bodenfläche bei kleinem Platzangebot für die Vorrichtung beansprucht wird. Zum andern ist zur Aufnahme der Stützrollen eine Grundplatte notwendig. Die Hohlprofilform der Streben bedingt eine gewisse Breite, welche jedoch zu ihrer Steifigkeit nur wenig beiträgt, sich jedoch gewichtsmäßig negativ auswirkt. Da die Patientengewichtskraft nicht direkt von den Streben, sondern erst indirekt über die Grundplatte aufgenommen wird, entsteht ein Verlust an Steifigkeit. Des Weiteren benötigt dieses Konstruktionsprinzip viele Einzelteile, die erst mechanisch fest miteinander verbunden werden müssen.The DE 196 47 498 A1 describes a device for raising patients from a sitting to an upright position. This has a frame, which consists of four perpendicular to each other arranged hollow profile-shaped struts, wherein the shorter struts formed between the longer struts are arranged. The frame surrounds a base plate. Between the base plate and a footrest support rollers are uniformly distributed over the circumference arranged. These serve to record the patient's weight and the Drehermöglichung the patient. The disadvantage of this design is that a large floor space is claimed in a small amount of space for the device.

Die DE 10 2006 039 602 A1 offenbart eine Vorrichtung zum Umsetzen einer Person. Diese weist eine bodenseitige Basisplatte und eine Drehscheibe auf zwischen denen eine Mehrzahl von Tragarmen angeordnet sind. Der wesentliche Nachteil dieser Konstruktion liegt darin, dass die Tragarme nicht direkt miteinander verbunden, sondern nur über die dünne Bodenplatte miteinander verknüpft sind. Demgemäß kommt es zwischen den Tragarmen wegen des geringen Widerstands- bzw. Trägheitsmomentes der Bodenplatte zu einer Steifigkeitsminderung des Fahrgestells, was sich dann beim Umsetzen von schweren Personen dadurch zeigt, dass die Bodenplatte sich stark durchbiegt und damit zusätzlich die Bodenfreiheit der Vorrichtung vermindert wird. Weiterhin weist die schwere Basisplatte hohe Herstellungskosten auf, da sie zunächst mittels Laserfertigung hergestellt und anschließend aufwändig mit den Tragarmen bestückt werden muss. Hinzu kommt, dass der geringe Abstand zwischen der Basisplatte und der Drehscheibe nur kleine und damit schwache Stützrollen erlaubt.The DE 10 2006 039 602 A1 discloses a device for implementing a person. This has a base-side base plate and a turntable between which a plurality of support arms are arranged. The main disadvantage of this design is that the support arms are not directly connected to each other, but are linked together only through the thin bottom plate. Accordingly, it comes between the support arms due to the low resistance or moment of inertia of the bottom plate to a rigidity reduction of the chassis, which then shows when moving heavy persons in that the bottom plate bends strongly and thus in addition the ground clearance of the device is reduced. Furthermore, the heavy base plate on high production costs, since they must first be made by laser production and then laboriously equipped with the support arms. In addition, the small distance between the base plate and the hub allows only small and thus weak support rollers.

Es ist Aufgabe der vorliegenden Erfindung, ein Fahrgestell mit einer darauf drehbaren Patientenplattform zur Verfügung zu stellen, welches eine hohe Steifigkeit aufweist und gleichzeitig mit wenigen Bauteilen eine kompakte und leichte Bauweise ermöglicht. Ferner sollen auf der Plattform Andockmöglichkeiten für Patientenaufstehhilfen, Patientenlifter und Stehtrainer vorgesehen sein.It is an object of the present invention to provide a chassis with a rotatable patient platform available, which has a high rigidity and at the same time allows a compact and lightweight design with few components. Furthermore, docking possibilities for patient support aids, patient lifts and standing trainers should be provided on the platform.

Offenbarung der ErfindungDisclosure of the invention

Diese Aufgabe wird durch das erfindungsgemäße Fahrgestell gelöst. Dieses weist eine Patientenplattform auf. Eine Nabe ist so in der Mitte der Patientenplattform angeordnet, dass die Patientenplattform drehbar um die Nabe gelagert ist. Mehrere Tragarme sind mit der Nabe verbunden. Die Tragarme sind außerdem miteinander verbunden. An jedem Ende eines Tragarms ist mindestens ein Rollkörper angeordnet. Mehrere Stützrollen sind so unterhalb der Patientenplattform an Schenkeln der Tragarme angeordnet, dass die Patientenplattform auf den Stützrollen gelagert ist und um die Nabe drehbar ist. Sowohl die Rollkörper als auch die Stützrollen sind insbesondere unmittelbar oder einstückig mit den Tragarmen verbunden.This object is achieved by the chassis according to the invention. This has a patient platform. A hub is located in the center of the patient platform such that the patient platform is rotatably mounted about the hub. Several brackets are connected to the hub. The brackets are also connected to each other. At least one rolling element is arranged at each end of a support arm. Several support rollers are arranged below the patient platform on legs of the support arms, that the patient platform is mounted on the support rollers and is rotatable about the hub. Both the rolling elements and the support rollers are in particular directly or integrally connected to the support arms.

Eine zusätzlich zu der Patientenplattform vorgesehene Basisplatte ist im erfindungsgemäßen Fahrgestell unnötig, da die Tragarme selbst mittels an ihren Schenkeln angebrachten Rollenhaltern die Aufnahme der Stützrollen übernehmen können. Zudem bilden die miteinander verbundenen Tragarme einen Kraftknoten, was eine Basisplatte ebenfalls überflüssig macht. Unter einem Kraftknoten wird erfindungsgemäß der Punkt der Krafteinleitung gemäß DIN 75078-2 verstanden. Indem jedes Ende eines Tragarms einen Rollkörper tragen kann, erfüllt ein Tragarm des erfindungsgemäßen Fahrgestells die Aufgabe von zwei Tragarmen herkömmlicher Fahrgestelle. Dies bedeutet einen geringeren Montageaufwand.A provided in addition to the patient platform base plate is unnecessary in the chassis according to the invention, since the support arms can take over the recording of the support rollers even by means mounted on their legs roll holders. In addition, the interconnected support arms form a power node, which also makes a base plate superfluous. A force node according to the invention is understood to mean the point of introduction of force according to DIN 75078-2. By each end of a support arm can carry a rolling body, a support arm of the chassis according to the invention fulfills the task of two support arms of conventional chassis. This means less installation effort.

In einer Ausführungsform der Erfindung ist es bevorzugt, dass die Tragarme aus einem gebogenem Flachmaterial bestehen. Dieses kann einfach mittels eines Lasers ausgeschnitten und gebogen werden. Aus den profilhochkant gestellten und miteinander verbundenen Tragarmen resultiert eine großes Trägheits- und Widerstandsmoment, was wiederum eine hohe Steifigkeit des gesamten Fahrgestells bedeutet. Durch die - von oben betrachtet - dünnen Tragarme entsteht gleichzeitig mehr Platz zwischen den Tragarmen, so dass beispielsweise ein Rollstuhl unproblematisch an die Patientenplattform herangefahren werden kann. Des Weiteren besteht ein Vorteil darin, dass die in Profilquerrichtung bestehende dünne Materialdicke der Tragarme sich positiv auf das Fahrgestellgewicht auswirkt.In one embodiment of the invention, it is preferred that the support arms consist of a bent sheet material. This can simply be cut out and bent by means of a laser. From the profiled upright and connected support arms results in a large moment of inertia and resistance, which in turn means a high rigidity of the entire chassis. The - viewed from above - thin support arms creates more space between the support arms, so that, for example, a wheelchair unproblematically moved up to the patient platform can be. Furthermore, there is an advantage in that the thin material thickness of the support arms in the transverse direction of the profile has a positive effect on the chassis weight.

In einer alternativen Ausführungsform der Erfindung ist es bevorzugt, dass die Schenkel der Tragarme jeweils in einem Gussteil zusammengefasst sind.In an alternative embodiment of the invention, it is preferred that the legs of the support arms are each combined in a casting.

An jedem Schenkel steht vorzugsweise eine Stützrolle einer weiteren Stützrolle auf der gegenüberliegenden Seite desselben Schenkels gegenüber.On each leg is preferably a support roller of another support roller on the opposite side of the same leg opposite.

Die Tragarme weisen bevorzugt parallel zueinander verlaufende Abschnitte auf und sind über diese parallel verlaufenden Abschnitte miteinander verbunden. In einer Ausführungsform der Erfindung ist es besonders bevorzugt, dass die parallel verlaufenden Abschnitte unmittelbar miteinander verbunden sind. In einer anderen Ausführungsform der Erfindung ist es besonders bevorzugt, dass die parallel verlaufenden Abschnitte mittels parallel verlaufender Hochstege miteinander verbunden sind. Dabei kann zwischen den Hochstegen horizontal eine Halteplatte verankert sein, auf der die Nabe befestigt ist. In noch einer anderen Ausführungsform der Erfindung ist es besonders bevorzugt, dass die parallel verlaufenden Abschnitte mittels horizontal übereinander verlaufender Stege miteinander verbunden sind. Am oberen dieser Stege kann die Nabe befestigt werden. In noch einer anderen Ausführungsform der Erfindung ist es besonders bevorzugt, dass die parallel verlaufenden Abschnitte mittels einer Traverse miteinander verbunden sind. Dabei ist es ganz besonders bevorzugt, dass die Traverse mindestens ein Hohlprofil aufweist, welches mindestens eine Antikippsicherungsschiene führt.The support arms preferably have mutually parallel sections and are connected to each other via these parallel sections. In one embodiment of the invention, it is particularly preferred that the parallel sections are directly connected to each other. In another embodiment of the invention, it is particularly preferred that the parallel sections are interconnected by means of parallel high webs. It can be anchored horizontally between the high webs a support plate on which the hub is mounted. In yet another embodiment of the invention, it is particularly preferred that the parallel sections are connected to each other by means of horizontally stacked webs. At the top of these webs, the hub can be attached. In yet another embodiment of the invention, it is particularly preferred that the parallel sections are interconnected by means of a crossbar. It is very particularly preferred that the traverse has at least one hollow profile, which leads at least one anti-tilt bar.

Die Patientenplattform weist an ihrem Außenumfang vorzugsweise Nuten auf, die eingerichtet sind, damit Riegel, insbesondere Fallriegel, in die Nuten eingreifen können.The patient platform preferably has grooves on its outer circumference, which are configured so that bolts, in particular latch bolts, can engage in the grooves.

Bevorzugt weist die Patientenplattform Andockpunkte für Patientenaufstehhilfen und/oder Patientenlifter und/oder Stehtrainer auf. Alternativ oder zusätzlich weist die Patientenplattform auf ihrer den Tragarmen abgewandten Seite einen Mitnehmer auf, der Andockpunkte für Patientenaufstehhilfen und/oder Patientenlifter und/oder Stehtrainer aufweist.The patient platform preferably has docking points for patient standing aids and / or patient lifts and / or standing trainers. Alternatively or additionally, the patient platform on its side facing away from the support arms on a driver, the docking points for patient support aids and / or patient hoist and / or standing coach has.

Ausführungsbeispiele der ErfindungEmbodiments of the invention

In einem ersten Ausführungsbeispiel des erfindungsgemäßen Fahrgestells, das in den Fig. 1 bis 3 dargestellt ist, weist dieses zwei Tragarme 6, 7 auf, welche jeweils aus Flachmaterial ausgeschnitten sind. Jeder Tragarm 6, 7 weist einen Abschnitt 62, 72 auf, von dem zwei Schenkel 60, 61, 70, 71 in dieselbe Richtung abgewinkelt sind. Die Schenkel 60, 61 des ersten Tragarms 6 verlaufen linear. Die Schenkel 70, 71 des zweiten Tragarms 7 sind zueinander hin abgewinkelt. Die beiden Abschnitte 62, 72 verlaufen parallel. An den Abschnitten 62, 72 sind die Tragarme 6, 7 über Hochstege 11 fest miteinander verbunden, wodurch ein Kraftknoten gebildet wird. Die Hochstege 11 ihrerseits sind oberseitig mit einer auf ihnen befestigten Nabenhalteplatte 12 versehen. Darauf angebracht ist eine Nabe 2, welche als Radiallager einer drehbaren Patientenplattform 1 dient. Ein mit einer Lagerbuchse 4 ausgerüsteter Mitnehmer 5 ist auf der Patientenplattform 1 fixiert und umschließt die feststehende Nabe 2, welche mit einem an ihrer Oberseite aufweisenden Lagerdeckel 3 verhindert, dass die Patientenplattform 1 im Betrieb über das zulässige vertikale Lagerspielmaß hinaus ausweicht. Zur horizontalen Abstützung der Patientenplattform 1 und deren Drehermöglichung sind an den Schenkeln 60, 61, 70, 71 der Tragarme 6, 7 Rollenhalter 10 mit daran enthaltenen Stützrollen 9 angebracht. An jedem Schenkel 60, 61, 70, 71 stehen sich zwei Stützrollen 9 gegenüber. Die Tragarme 6, 7 weisen jeweils an beiden Enden Rollkörper 8 zur Verfahrbarkeit des Fahrgestells auf. Die Patientenplattform 1 weist an ihrem Außenumfang Nuten (nicht dargestellt) auf. Diese sind eingerichtet, damit Fallriegel (nicht dargestellt) in die Nuten eingreifen können. Die Fallriegel sind an den Schenkeln 60, 61, 70, 71 der Tragarme 6, 7 vertikal schwenkbar befestigt. Sie können die Patientenplattform 1 temporär in einer bestimmten Winkelposition zur Nabe 2 fixieren. Um eine Patientenaufstehhilfe, einen Patientenlifter oder einen Stehtrainer auf der Patientenplattform 1 befestigen zu können, weisen die Patientenplattform 1 und der Mitnehmer 5 Andockpunkte (nicht dargestellt) für Patientenaufstehhilfen, Patientenlifter oder Stehtrainer auf.In a first embodiment of the chassis according to the invention, which in the Fig. 1 to 3 is shown, this has two support arms 6, 7, which are each cut out of flat material. Each support arm 6, 7 has a portion 62, 72, of which two legs 60, 61, 70, 71 are angled in the same direction. The legs 60, 61 of the first support arm 6 are linear. The legs 70, 71 of the second support arm 7 are angled towards each other. The two sections 62, 72 are parallel. At the sections 62, 72, the support arms 6, 7 are firmly connected to each other via high webs 11, whereby a force node is formed. The high webs 11 in turn are provided on the upper side with a hub holding plate 12 fastened to them. Attached thereto is a hub 2, which serves as a radial bearing of a rotatable patient platform 1. A driver 5 equipped with a bearing bush 4 is fixed on the patient platform 1 and encloses the fixed hub 2, which prevents a bearing cap 3 having on its upper side, that the patient platform 1 evades in operation beyond the permissible vertical bearing clearance. For horizontal support of the patient platform 1 and its Drehermöglichung 7 roller holders 10 are attached to the legs 60, 61, 70, 71 of the support arms 6, 7 with support rollers contained therein. On each leg 60, 61, 70, 71 are opposed to two support rollers 9. The support arms 6, 7 each have at both ends rolling body 8 to the mobility of the chassis. The patient platform 1 has grooves (not shown) on its outer circumference. These are arranged so that latch (not shown) can engage in the grooves. The latch bolts are attached to the legs 60, 61, 70, 71 of the support arms 6, 7 vertically pivotally mounted. You can fix the patient platform 1 temporarily in a certain angular position to the hub 2. To be able to attach a patient support, a patient lift or a standing coach on the patient platform 1, the patient platform 1 and the driver 5 docking points (not shown) for patient support aids, patient lift or standing coach on.

In einem nicht dargestellten zweiten Ausführungsbeispiel wird der Kraftknoten nicht mittels vertikal angeordneter Hochstege erzeugt. Stattdessen wird er mittels horizontal zwischen den beiden Abschnitten 62, 72 und diese an deren Ober- und Unterseite fest verbindenden Stegen gebildet.In a second embodiment, not shown, the power node is not generated by means of vertically arranged webs. Instead, it is formed by means of horizontally between the two sections 62, 72 and these at the top and bottom firmly connecting webs.

In einem weiteren nicht dargestellten dritten Ausführungsbeispiel wird der Kraftknoten ausschließlich über die beiden Abschnitte 62, 72 gebildet. Hierzu sind diese direkt fest miteinander verbundenen. Die Nabe 2 wird mit einer an ihrer Unterseite eingefrästen Nut über die Feder der verbundenen Abschnitte 62, 72 gesteckt und mit diesen ebenfalls fest verknüpft, um eine Nut-Feder-Verbindung zu erhalten.In a further third exemplary embodiment, which is not shown, the force node is formed exclusively via the two sections 62, 72. For this purpose, these are directly connected to each other. The hub 2 is inserted with a groove milled on its underside on the spring of the connected portions 62, 72 and also firmly linked with these, to obtain a tongue and groove connection.

Ein viertes Ausführungsbeispiel der Erfindung ist in den Figuren 4 bis 6 dargestellt. Hierin weisen die Abschnitte 62, 72 eine sie fest verbindende Traverse 13 und damit einen sich bildenden Kraftknoten auf. Die Traverse 13 ihrerseits beinhaltet neben steifigkeitserhöhenden Zwischenstegen 80 noch zwei Hohlprofile 161,171 in welchen jeweils eine Antikippsicherungsschiene 16, 17 geführt ist. Die Antikippsicherungsschiene 16, 17 weist an ihrem, vom Kraftknoten wegzeigenden Ende, einen um 90° vertikal schwenkbaren Kipphebel 20, 21 auf. Die beiden möglichen Positionen dieser Kipphebel 20, 21 sind in den Figuren 4 und 5 dargestellt. An der ausgefahrenen Antikippsicherungsschiene 17 ist der Kipphebel 21 nach unten geschwenkt. Er erhält so annähernd Bodenkontakt, um im Falle, dass ein Patient mit seinem Körperschwerpunkt über die Plattform 1 hinaus gelangt, ein Gegenmoment zur Vorbeugung einer Fahrgestell-Kippung zu erzeugen. An der zurückgeschobenen Antikippsicherungsschiene 16 ist der Kipphebel 20 nach oben geschwenkt.A fourth embodiment of the invention is in the FIGS. 4 to 6 shown. Here, the sections 62, 72 have a traverse 13 which firmly connects them and thus a forming force node. The traverse 13 in turn contains in addition to stiffness-increasing intermediate webs 80 still two hollow sections 161,171 in each of which a Antikippsicherungsschiene 16, 17 is guided. The Antikippsicherungsschiene 16, 17 has at its, pointing away from the power node end, a 90 ° vertically pivotable rocker arm 20, 21. The two possible positions of these rocker arms 20, 21 are in the FIGS. 4 and 5 shown. At the extended Antikippsicherungsschiene 17 of the rocker arm 21 is pivoted downwards. He thus receives approximately ground contact, in order, in the event that a patient passes with his body of gravity beyond the platform 1, to generate a counter-torque to prevent a chassis tilting. At the pushed back Antikippsicherungsschiene 16 of the rocker arm 20 is pivoted upwards.

In jedem der aufgeführte Ausführungsbeispiele des Fahrgestells können die Schenkel 60, 61, 70, 71 der Tragarme 6, 7 jeweils in einem Gussteil zusammengefasst sein, anstatt dass die Tragarme 6, 7 aus einem Flachmaterial ausgeschnitten sind.In each of the illustrated embodiments of the chassis, the legs 60, 61, 70, 71 of the support arms 6, 7 may each be combined in a casting, instead of the support arms 6, 7 are cut out of a flat material.
