    • Fig.2 the platform 3 in the folded position;
    • Figure 3 the electric drive 1 in a particularly advantageous embodiment, from below.
  • Ausführung der ErfindungEmbodiment of the invention
  • Fig.1 zeigt den erfindungsgemäßen Elektroantrieb 1 an einem konventionellen, serienmäßig produzierten Rollator 2 in perspektivischer Ansicht in einer bevorzugten Ausführungsform. Je nach Ausführung des serienmäßigen Rollators 2 können dafür technische Anpassungen erforderlich sein. Fig.1 shows the electric drive 1 of the invention on a conventional, mass-produced rollator 2 in a perspective view in a preferred embodiment. Depending on the version of the standard rollator 2 technical adjustments may be required.
  • Wie aus Fig.1 ersichtlich, sind an der Plattform 3 in einer besonders vorteilhaften Ausgestaltung des Elektroantriebes 1 zu ihrer Fortbewegung Laufräder 4 vorgesehen. Die Lenkbarkeit des Elektroantriebs 1 ist für den Antrieb des Rollators 2 entscheidend und muss daher besonderen Anforderungen hinsichtlich seines Lenkverhaltens bestehen. Um diesen Anforderungen gerecht zu werden, sind einzelne oder sämtliche Laufräder 4 vorteilhafterweise als Lenkrollen 8 ausgestaltet, Zusätzlich sollte der Drehpunkt, über den die Plattform 3 mit dem Rollator 2 verbunden ist, möglichst nahe der Plattform liegen. Vorzugsweise sind hierzu Lenkrollen 8 zumindest im vorderen Bereich unterhalb der Plattform 3 angeordnet, nahe dem Bereich, in dem die Befestigungselemente 6 angeflanscht sind. In einer weiteren Ausführungsform könnte die Plattform 3 insgesamt selbst lenkbar konstruiert werden, so dass das Zusammentreffen mit den Rädern des Rollators 2 bei Kurvenfahrten gänzlich unterbunden würde.How out Fig.1 can be seen, wheels 4 are provided on the platform 3 in a particularly advantageous embodiment of the electric drive 1 for their movement. The steerability of the electric drive 1 is crucial for the drive of the rollator 2 and therefore has special requirements with regard to its steering behavior. To meet these requirements, individual or all wheels 4 are advantageously designed as castors 8, In addition, the pivot point over which the platform 3 is connected to the rollator 2 should be as close to the platform. Preferably, for this purpose, steering rollers 8 are arranged at least in the front region below the platform 3, near the area in which the fastening elements 6 are flanged. In a further embodiment, the platform 3 could be constructed as a whole steerable itself, so that the meeting with the wheels of the rollator 2 would be completely prevented when cornering.
  • Vorzugsweise ist der Elektromotor 5 selbst unterhalb der Plattform 3 angeordnet. Mit dessen Hilfe kann über ausgewählte Laufräder 4 die Bewegung der Plattform 3 realisiert werden. Vorzugsweise ist der unter der Plattform 3 befindliche Elektromotor 5 mit einer elektronischen Steuerungseinrichtung versehen, die ein sanftes und ruckelfreies Anfahren der Plattform 3 gewährleistet. Um ein sanftes Anfahren der Plattform 3 zu erreichen, können aber auch entsprechende dem Fachmann bekannte mechanische Komponenten an dem Elektroantrieb 1 bzw. der Plattform 3 eingesetzt werden, beispielsweise hydromechanische Antriebselemente (Kupplung, Getriebe) oder dergleichen.Preferably, the electric motor 5 itself is arranged below the platform 3. With the help of selected wheels 4, the movement of the platform 3 can be realized. Preferably located under the platform 3 electric motor 5 is provided with an electronic control device, which ensures a smooth and smooth starting of the Platform 3 guaranteed. In order to achieve a smooth start-up of the platform 3, however, corresponding mechanical components known to the person skilled in the art can also be used on the electric drive 1 or the platform 3, for example hydromechanical drive elements (clutch, transmission) or the like.
  • In einer besonders vorteilhaften Ausführung des Elektroantriebs 1 ist dieser - wie in Fig.1 dargestellt - beweglich mit dem Rollator 2 verbunden. Dadurch kann der Nutzer durch wechselseitiges Betätigen der Bremsen des Rollators 2 einen Lenkvorgang auslösen.In a particularly advantageous embodiment of the electric drive 1 is this - as in Fig.1 shown - movably connected to the rollator 2. As a result, the user can trigger a steering operation by alternately actuating the brakes of the rollator 2.

Bei dieser besonders bevorzugten Ausgestaltung des Elektroantriebs 1 bzw. der Befestigungselemente 6 der Plattform 3 kann diese, wenn der Elektroantrieb 1 nicht benötigt wird, hochgeklappt bzw. an den Rollator 2 angeklappt werden. Der Rollator 2 ist dann in der gewohnten Weise als Gehhilfe nutzbar. Fig.2 shows the electric drive 1 according to the invention in the folded-up position. In this particularly preferred embodiment of the electric drive 1 or the fastening elements 6 of the platform 3, this can, when the electric drive 1 is not needed, folded up or folded onto the rollator 2. The rollator 2 can then be used in the usual way as a walker.
  • Um das Gewicht des Rollators 2 bei seiner Verwendung in dieser Ausführungsform möglichst zu reduzieren, sollten die einzelnen Bauteile des Elektroantriebs 1 bzw. der Plattform 3, der Antriebselemente 5 sowie Laufräder 4 und Befestigungselemente 6 aus einem leichten Material, z. B. Aluminium oder einem festen Kunststoff, gefertigt sein. Nach dem Hochklappen der Plattform 3 wird diese an dem Rollator 2 vorzugsweise mittels einer oder mehrerer Befestigungseinrichtungen arretiert.In order to reduce the weight of the rollator 2 as possible in its use in this embodiment, the individual components of the electric drive 1 and the platform 3, the drive elements 5 and wheels 4 and fasteners 6 should be made of a lightweight material, eg. As aluminum or a solid plastic, be made. After folding up the platform 3, it is preferably locked to the rollator 2 by means of one or more fastening devices.
  • Um ein sanftes Ablassen der Plattform 3 zu gewährleisten, können die Befestigungselemente 6 in einer vorteilhaften Ausführung mindestens eine Dämpfungseinrichtung aufweisen, beispielsweise in Form von Hydraulikzylindern, Federn oder einer bzw. mehrerer Bremsen.In order to ensure a gentle deflation of the platform 3, the fastening elements 6 may have in an advantageous embodiment at least one damping device, for example in the form of hydraulic cylinders, springs or one or more brakes.
  • Fig.3 zeigt den Elektroantrieb 1 in einer besonders vorteilhaften Ausführung, von unten. Wie aus Fig.3 ersichtlich, erfolgt das Absenken und das Hochklappen der Plattform 3 mit Hilfe des Elektromotors 5, beispielsweise über ein Gurtband 7, welches auf einer Rolle aufwiekefbar ist. Figure 3 shows the electric drive 1 in a particularly advantageous embodiment, from below. How out Figure 3 it can be seen, the lowering and the folding up of the platform 3 by means of the electric motor 5, for example via a webbing 7, which aufwiekefbar on a roll.
  • Der Elektromotor 5 dient vorteilhafterweise gleichzeitig dem Antrieb als auch dem Hochklappen der Plattform 3. Der Antrieb kann hierzu jeweils über Treibriemen mit Zahnung (Zahnriemen 10,11) erfolgen, die formschlüssig in gezahnten Riemenscheiben laufen, die vorzugsweise axial nebeneinander an der Antriebswelle des Elektromotors 5 angeordnet sind. Besonders bevorzugt ist an der Einrichtung zum Hochklappen / Senken der Plattform 3 ein Kupplungs- und Bremssystem (bestehend aus Kupplung 12, Bremse 14 und Zugmagneten 13) vorgesehen.The drive can be done for this purpose respectively via drive belt with teeth (toothed belt 10,11), which run positively in toothed pulleys, preferably axially adjacent to each other on the drive shaft of the electric motor. 5 are arranged. Particularly preferably, a coupling and brake system (consisting of coupling 12, brake 14 and tension magnet 13) is provided on the device for folding / lowering the platform 3.
  • Dadurch kann bei der Verwendung des Elektroantriebs 1 für den Nutzer jegliches Bücken oder Heben vermieden werden. Die Steuerung kann vorzugsweise per Knopfdruck betätigt werden, wobei der Vorgang zur Vermeidung von Verletzungen jeweils von einem Sicherheitssystem überwacht werden kann. In einer besonders bevorzugten Ausführung erfolgt die Dämpfung der Plattform 3 beim Ablassen in der Weise, dass an der Rolle des Gurtbandes 7 eine Bremse 14 vorgesehen ist. Der für das Absenken und/oder Hochklappen verwendete Elektroantrieb ist vorzugsweise ebenfalls der Elektromotor 5.As a result, when using the electric drive 1 for the user any bending or lifting can be avoided. The control can preferably be actuated by pressing a button, wherein the process for preventing injury can be monitored by a security system. In a particularly preferred embodiment, the damping of the platform 3 during deflation occurs in such a way that a brake 14 is provided on the roller of the webbing 7. The electric drive used for lowering and / or folding up is preferably also the electric motor 5.
