Abstract
Ein elektrisch leitfähiger Rollenbeschlag eines fahrbaren Möbels wie eines Rollenstuhls oder -bettes zur Ableitung der eletrostatischen Ladung auf den Boden, umfassend ein Rollenpaar mit zwei koaxial auf einer Achse drehbar gelagerten, elektrisch unleitfähigen Rollen (2) und eine Nabe (11) aufweist, die außermittig über ein Gelenk um eine vertikale Achse schwenkbar am unteren Ende eines Beins des Rollenstuhls oder -bettes gelagert ist, wobei die beiden Rollen (2) unter Bildung eines Zwischenraums mit Abstand voneinander angeordnet sind, in dem ein elektrisch leitfähiges Rädchen (24) drehbar gehalten und federelastisch gegen den Boden angedrückt ist, dadurch gekennzeichnet, daß das Rädchen (24) über einen zwischen den beiden Rollen (2) federnd um eine Querachse (222) schwenkbar gehaltenen Schwenkhebel (22) zwischen den beiden Rollen (2) gelagert ist, der nach hinten gekippt angeordnet ist.One electrically conductive Roller fitting of a mobile furniture such as a roller chair or bed for the derivation of eletrostatic Charge to the ground, comprising a pair of rollers with two coaxial On an axis rotatably mounted, electrically non-conductive rollers (2) and a hub (11) which eccentrically via a joint about a vertical Axis pivoting at the lower end of a leg of the roller chair or Bed is stored, the two rollers (2) under education a space spaced apart, in an electrically conductive cogs (24) rotatably supported and resiliently pressed against the ground, characterized characterized in that cogs (24) about one between the two rollers (2) resiliently about a transverse axis (222) pivotally held pivot lever (22) between the two rollers (2) is mounted, which is arranged tilted backwards.
Description
[Technisches Gebiet][Technical area]
Die Erfindung betrifft einen elektrisch leitfähigen Rollenbeschlag, insbesondere für einen Rollenstuhl oder ein Rollenbett.The The invention relates to an electrically conductive roller fitting, in particular for one Roller chair or a roll bed.
[Stand der Technik][State of the art]
Bei der instrumentellen Diagnose eines körperbehinderten Patienten, der auf einem Rollenstuhl oder einem Rollenbett aufsitzen oder -liegen muß, werden zur Vermeidung einer Störung infolge der elektrostatischen Ladung leitfähige Rollenbeschläge eingesetzt, um die elektrische Ladung auf den Boden abzuleiten. Zu diesem Zweck sind die Beine und die Rollenbeschläge eines solches Rollenstuhls oder -betts aus elektrisch leitfähigen Werkstoffen wie Metall hergestellt oder mit diesen überzogen. Hierdurch gilt der Rollenstuhl oder das Rollenbett als "geerdet", wobei eine elektrostatische Ladung vom Rollenstuhl oder -bett über ein metallisches Bein und eine metallische Achse auf eine elektrische leitfähige Laufrolle und dort über ihre Lauffläche auf den Boden abgeleitet wird. Hier kann die Rolle entweder einstückig aus einem Metall (eine metallische Lauffläche) hergestellt oder mit einem leitfähigen Gummi bereift sein. Im Falle einer rein metallischen Rolle fehlt es eine Dämpfung. Dagegen ist bei einem Rollenbeschlag mit einem Reifen aus elektrisch leitfähigem Gummi fehlt dieser eine Verschleißbeständigkeit und daher hat eine nur kurze Standzeit.at the instrumental diagnosis of a physically handicapped patient, sitting or lying on a roller chair or a roll bed must be to avoid a disturbance used as a result of the electrostatic charge conductive roller fittings, to divert the electrical charge to the ground. To this end are the legs and the roller fittings of such a roller chair or bed of electrically conductive Materials such as metal produced or coated with these. As a result, the roller chair or the roller bed is considered "grounded", with an electrostatic Cargo from rolling chair or bed over a metallic leg and a metallic axle on an electric conductive roller and over there her tread is derived to the ground. Here the role can be either one-piece from one Metal (a metallic tread) manufactured or with a conductive Rubber be frosted. In the case of a purely metallic role is missing it's a cushioning. In contrast, in a roller fitting with a tire made of electric conductive Rubber lacks this one wear resistance and therefore has one only short life.
So
in einer alten Erfindung des Erfinders wurde vorgeschlagen (siehe
Damit
das elektrische Rädchen
Der Erfindung liegt die Aufgabe zugrunde, einen elektrisch leitfähigen Rollenbeschlag zu schaffen, mit dem die o.g. Nachteile vermieden werden.Of the Invention is based on the object, an electrically conductive roller fitting to create, with the o.g. Disadvantages are avoided.
Nachteilig
ist beim "Sandwich-Rollenbeschlag", daß die Verlagerung
des innenliegenden Rädchens
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Rädchen nicht über eine vertikale federnde Führung, sondern über einen zwischen den beiden Rollen federnd um eine Querachse schwenkbar gehaltenen Schwenkhebel zwischen den beiden Rollen gelagert, der nach hinten gekippt angeordnet ist. Auf diese Weise kann bei Kontakt mit einer schmalen, steilen Erhebung das Rädchen gegen die Federwirkung nach hinten geschwenkt werden und diese problemlos überfahren.These Task is inventively characterized solved, that this cogs no over a vertical resilient guide, but about one between the two rollers resiliently pivotable about a transverse axis held pivot lever mounted between the two rollers, the arranged tilted backwards. That way, when in contact with a narrow, steep elevation the wheel against the spring effect be swung to the rear and run over these easily.
Die Erfindung wird nachfolgend anhand einer in der Zeichnung dargestellten Ausführiungsform näher erläutert. Es zeigen:The Invention will now be described with reference to a drawing Implementation form explained in more detail. It demonstrate:
