Description
Die Erfindung betrifft einen Rollstuhllift an Nutzfahrzeugen, insbesondere Omnibussen.The invention relates to a wheelchair lift on commercial vehicles, especially buses.
Es sind Rollstuhllifte an Omnibussen bekannt, die mittels Spindelantrieb oder vertikal angeordneter Hydraulikzylinder gesenkt und gehoben werden. Diese Antriebseinrichtungen sind in ihrer Höhenausdehnung platzraubend und stören vor allem im Bereich der am Einstieg angeordneten Sitze.There are wheelchair lifts on buses that use Spindle drive or vertically arranged hydraulic cylinder be lowered and raised. These drive devices are in terms of its height, it is bulky and, above all, disturbs in the area of the seats arranged at the entrance.
Der Erfindung liegt die Aufgabe zugrunde, in Omnibussen eine Einstieghilfe für Rollstuhlfahrer, mit geringem Platzbedarf, vor allem hinsichtlich der Hebeeinrichtung, zu schaffen.The invention is based on the object in buses Entry aid for wheelchair users, with little space requirement, especially with regard to the lifting device.
Dies wird erfindungsgemäß dadurch gelöst, daß zur Überwindung der Einstieghöhe von der Fahrbahn- bzw. Bordsteinebene zur Mittelganghöhe eine Hub/Senkvorrichtung mit einem Parallelo grammlenkergetriebe von geringer Gesamthöhe (a) und kleinster Ausladung (b) vorgesehen ist und das Parallelogrammlenkerge triebe von einem fluidbeaufschlagten, mit dem Omnibus orts fest, aber schwenkbar, verbundenen Zylinder angetrieben ist. Solcherart wird mit einem Antriebsorgan eine Verschiebung der Plattform für den Rollstuhl in zwei Ebenen erreicht, wo bei das Parallelogrammlenkergetriebe so ausgelegt werden kann, daß es den unterschiedlichsten Anforderungen, auch im Hinblick auf verschiedene Omnibustypen, gerecht wird.This is achieved according to the invention in that, in order to overcome the entry height from the roadway or curb level to the central aisle height, a lifting / lowering device with a parallelogram handlebar transmission of low overall height ( a ) and smallest projection ( b ) is provided and the parallelogram linkage is driven by a fluid-loaded, with the omnibus fixed, but pivotable, connected cylinder is driven. In this way, the drive for the wheelchair is displaced in two planes with a drive element, where the parallelogram link mechanism can be designed in such a way that it meets the most varied of requirements, including with regard to different types of buses.
Nach einem wesentlichen Merkmal der Erfindung ist die äußere Schwinge als Winkelhebel ausgebildet, dessen über den Dreh punkt des einen Lagers herausragender Arm gelenkig mit dem Kolben des horizontal zur Mittelgangebene angeordneten Zylin ders verbunden ist und der Zylindermantel ortsfest, aber schwenkbar, am Omnibus in einem Drehpunkt gelagert ist. Auf diese Weise kann mit einem Zylinder geringer Länge ein verhältnismäßig großer Hub und eine geringe seitliche Ausla dung erzielt werden, wobei der horizontal liegende Zylinder im Bereich unterhalb der Sitze angeordnet werden kann, so daß kein Platz im Businneren verschenkt wird.According to an essential feature of the invention, the outer Swing arm designed as an angle lever, its over the turn point of one bearing projecting arm articulated with the Piston of the cylinder arranged horizontally to the central aisle level ders connected and the cylinder jacket stationary, but swiveling, is mounted on the bus in a pivot point. In this way you can use a cylinder of short length relatively large stroke and a small lateral outlet can be achieved with the horizontal cylinder can be arranged in the area below the seats, so that no space inside the bus is given away.
Nach einem weiteren Merkmal der Erfindung ist die in Fahrzeu gen mit Servolenkung vorhandene Ölpumpe für die Servolenkung auch für den Betrieb des Antriebszylinders für die Hub/Senk einrichtung vorgesehen. Durch diese Maßnahme ist keine zu sätzliche Antriebsquelle notwendig, da die Pumpe in Halteposi tion des Omnibusses für die Servolenkung nicht benötigt wird und somit für das Heben und Senken des Rollstuhlliftes zur Verfügung steht, was zur Verbilligung der Einrichtung bei trägt.According to a further feature of the invention is in the vehicle Oil pump with power steering for power steering also for the operation of the drive cylinder for the lifting / lowering facility provided. With this measure, none is closed Additional drive source necessary because the pump is in stop position tion of the bus for power steering is not required and thus for lifting and lowering the wheelchair lift What is available to make the facility cheaper wearing.
Weitere Vorteile und Merkmale der Erfindung sind den Ansprü chen, der Figurenbeschreibung und der Zeichnung zu entnehmen.Further advantages and features of the invention are the claims Chen, the description of the figures and the drawing.
Die Erfindung ist in einem Ausführungsbeispiel dargestellt.The invention is shown in one embodiment.
Es zeigt:It shows:
Fig. 1 einen Rollstuhllift im angehobenen und (strichli niert) im abgesenkten Zustand. Fig. 1 shows a wheelchair lift in the raised and (dashed lines) in the lowered state.
Die Plattform 5 der Hub/Senkvorrichtung 6 ist zum Zweck eines Rollstuhlein- und -ausstiegs von der Mittelganghöhe 1 zu einer Fahrbahn- oder Bordsteinebene 2 um das Maß (h) absenkbar bei einer seitlichen Ausladung um das Maß (b). Für den Antrieb der Plattform 5 ist ein Parallelogrammlenkergetriebe 4 mit Zylinder 3 vorgesehen. Mit der Plattform 5 ist ein senkrecht stehendes Trägerblech 13 fest verbunden. Am Trägerblech 13 sind in den Gelenken 11 und 12 die Schwingen 9 und 10 ange lenkt, die anderenends in den busfesten Lagern 7 und 8 schwenkbar angeordnet sind. Die Schwinge 10, als Winkelhe bel ausgebildet, weist einen über das Lager 8 hinausragen den Arm 14 auf, der gelenkig mit dem Kolben 15 des horizon tal angeordneten Zylinders 3 verbunden ist, dessen Zylinder mantel 16 anderenends im Drehpunkt 17 ortsfest, aber drehbar, mit dem Omnibus verbunden ist. Der Zylinder 3 wird von einem Fluid beaufschlagt, vorzugsweise über die Ölpumpe für die Servolenkung, die bei Bushalt nicht für ihren ureigenen Zweck benötigt wird. The platform 5 of the lifting / lowering device 6 can be lowered by the dimension ( h ) for a wheelchair entry and exit from the central aisle height 1 to a roadway or curb level 2 with a lateral projection by the dimension ( b ). A parallelogram linkage 4 with cylinder 3 is provided for driving the platform 5 . A vertically standing support plate 13 is firmly connected to the platform 5 . On the support plate 13 , the rockers 9 and 10 are in the joints 11 and 12 , the other ends in the bus-fixed bearings 7 and 8 are pivotally arranged. The rocker 10 , formed as a Winkelhe bel, has a protruding beyond the bearing 8 on the arm 14 , which is articulated to the piston 15 of the horizontally arranged cylinder 3 , the cylinder jacket 16 at the other end at the pivot point 17 stationary, but rotatable, with connected to the omnibus. The cylinder 3 is acted upon by a fluid, preferably via the oil pump for the power steering, which is not required for its own purpose when the bus stops.
