Abstract
Description
Die Erfindung betrifft ein insbesondere für motorisch behinderte Personen geeignetes Laufrad mit wenigstens einem ein Hinterrad tragenden Hinterbau, einem wenig stens ein Vorderrad tragenden Vorderbau, einem Sattel und einer Lenkeinrichtung.The invention relates in particular to motor wheelchair suitable for disabled people with at least a rear wheel supporting a rear wheel, a little Mostly a front wheel bearing front structure, a saddle and a steering device.
Laufräder (auch als Draisine bezeichnet), bei denen der Fahrer auf einem Sattel sitzend sich mit den Füßen an dem Erdboden abstößt, fanden vor Erfindung des Tretrads Verwendung.Impellers (also called draisine), where the Rider sitting on a saddle with his feet repels the earth, found before the invention of the bicycle Use.
Vielen Menschen, insbesondere behinderten ist die Ver wendung eines solchen Fahrrads nicht möglich. Auch die - seit langem nicht mehr gebräuchlichen - Laufräder können von vielen Menschen nicht verwendet werden, da ihnen das Aufsteigen auf derartige Laufräder nicht möglich ist. Many people, especially disabled people, are not possible to use such a bicycle. Also the - Wheels that have not been used for a long time cannot be used by many people because they do not get on such wheels is possible.
Der Erfindung liegt die Aufgabe zugrunde, ein Laufrad zu schaffen, das von motorisch behinderten Personen verwendet werden kann und diesen so eine bisher nicht erreichte Mobilität geben.The invention has for its object an impeller to create that by motor disabled people can be used and so far not one give achieved mobility.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß der Sattel in seinem vorderen Bereich um eine horizon tale Achse nach unten verschwenkbar gelagert ist, wobei vorzugsweise eine den Sattel in der ausgeschwenkten Stellung sichernde Verriegelung vorgesehen ist.According to the invention, this object is achieved in that the saddle in its front area around a horizon tale axis is pivotally mounted down, wherein preferably one the saddle in the swung out Locking position is provided.
Vorzugsweise ist der Hinterbau in seinem dem Sattel benachbarten Bereich um eine zweite horizontale Achse verschwenkbar gelagert.The rear end is preferably in its saddle adjacent area around a second horizontal axis pivoted.
Dabei kann ein den Hinterbau mit dem Sattel verbinden des Untersetzungsgetriebe vorgesehen sein, das vorzugs weise aus drei Zahnrädern besteht.You can connect the rear triangle to the saddle the reduction gear can be provided, the preferred wise consists of three gears.
Um eine höhere Stabilität des Laufrades zu erreichen, ist vorzugsweise der Vorderbau mit zwei Vorderrädern versehen.In order to achieve a higher stability of the wheel, is preferably the front structure with two front wheels Mistake.
Die Erfindung wird im folgenden anhand einer Zeichnung erläutert. Dabei zeigtThe invention is described below with reference to a drawing explained. It shows
Fig. 1 eine Seitenansicht des Laufrades, Fig. 1 is a side view of the impeller,
Fig. 2 eine Vorderansicht des in Fig. 1 gezeig ten Laufrades, und Fig. 2 is a front view of the impeller shown in Fig. 1, and
Fig. 3 eine Fig. 1 entsprechende Darstellung in eingeschwenktem Zustand. Fig. 3 is a Fig. 1 corresponding representation in the pivoted state.
Das Laufrad besteht aus einem ein Hinterrad 10 tragen den Hinterbau 12, einem zwei Vorderräder 14, 14′ tra genden Vorderbau 16, einem Sattel 18 und einer Lenkein richtung 20.The impeller consists of a rear wheel 10 carry the rear end 12 , a two front wheels 14, 14 ' tra lowing front end 16 , a saddle 18 and a Lenkein direction 20th
Der Sattel 18 ist um eine im vorderen Bereich des Sat tels 18 angeordnete erste horizontale Achse 22 nach unten abschwenkbar (Fig. 3) gelagert. Der Hinterbau 12 ist in seinem oberen Bereich an den Vorderbau 16 um eine zweite horizontale Achse 26 nach vorne verschwenk bar (Fig. 3) gelagert. Hinterbau 12 und Sattel 18 sind über ein Übersetzungsgetriebe bestehend aus einem er sten, auf der ersten Achse 22 aufsitzenden Zahnrad 28, einem zweiten auf der zweiten Achse aufsitzenden Zahn rad 30 und ein drittes, mit dem ersten Zahnrad 22 und mit dem zweiten Zahnrad 30 in Eingriff stehenden Zahn rad 32 verbunden, so daß ein nach vorne Verschwenken des Hinterbaus 12 zu einem Abschwenken des hinteren Endes des Sattels 18 führt.The saddle 18 is pivoted about a arranged in the front region of the Sat 18 first horizontal axis 22 downward ( Fig. 3). The rear structure 12 is mounted in its upper region on the front structure 16 about a second horizontal axis 26 to the front ( FIG. 3). Rear triangle 12 and saddle 18 are via a transmission gear consisting of a he most, on the first axis 22 seated gear 28 , a second tooth on the second axis gear 30 and a third, with the first gear 22 and with the second gear 30 in Engaged gear wheel 32 connected so that a forward pivoting of the rear end 12 leads to a pivoting of the rear end of the saddle 18 .
Weiter ist eine Verriegelung 24 vorgesehen, die den Sattel 18 in der ausgeschwenkten Stellung verriegelt, wobei diese Verriegelung 24 manuell lösbar ist.Furthermore, a lock 24 is provided, which locks the saddle 18 in the pivoted-out position, wherein this lock 24 can be released manually.
Die Lenkeinrichtung 20 besteht aus einem Lenkrad, einer Lenkstange und Mitteln zum Übertragen der Lenkbewegung auf die Vorderräder 14, 14′, auf eine eingehende Be schreibung kann hier verzichtet werden, da die Ausbil dung derartiger Lenkeinrichtungen bekannt ist.The steering device 20 consists of a steering wheel, a steering rod and means for transmitting the steering movement to the front wheels 14, 14 ' , an in-depth description can be omitted here, since the training of such steering devices is known.
Die vorgeschlagene Ausgestaltung hat den Vorteil, daß das Aufsteigen auch motorisch behinderten Personen mög lich ist: Diese stellen sich in der in Fig. 3 gestell ten Stellung mit gespreizten Beinen hinter das Laufrad und ziehen sodann an den Griff der Lenkeinrichtung 20 zu sich heran. Dies bewirkt, daß der Vorderbau 16 des Laufrads sich um die erste horizontale Achse 22 relativ zu dem Hinterbau 12 nach vorne verschwenkt. Diese Rela tivdrehung bewirkt die Übertragung eines Drehmoments von dem zweiten Zahnrad 30 über das dritte Zahnrad 32 auf das erste Zahnrad 28, das mit dem Sattel 18 fest verbunden ist; das hintere Ende des Sattels 18 wird somit um die Achse 22 in die in Fig. 1 gezeigte Stel lung nach oben verschwenkt, der Fahrer sitzt jetzt auf dem Laufrad auf. Diese im wesentlichen horizontale Aus richtung des Sattels 18 wird durch Einlegen der Verrie gelung 24 in eine entsprechende Ausnehmung in dem Vor derbau 16 gesichert (obwohl an sich eine Stabilität des Sattels bei Belastung auch schon über das Getriebe bewirkt wird).The proposed embodiment has the advantage that the ascent is also possible for people with motor disabilities: these stand in the position shown in FIG. 3 with the legs apart behind the impeller and then pull the handle of the steering device 20 towards them. This causes the front structure 16 of the wheel to pivot forward about the first horizontal axis 22 relative to the rear structure 12 . This Rela tiv rotation causes the transmission of a torque from the second gear 30 via the third gear 32 to the first gear 28 , which is fixedly connected to the saddle 18 ; the rear end of the saddle 18 is thus pivoted upward about the axis 22 in the position shown in FIG. 1, the driver now sits on the wheel. This essentially horizontal direction of the saddle 18 is secured by inserting the locking 24 into a corresponding recess in the front derbau 16 (although in itself a stability of the saddle under load is already effected via the transmission).
Zum Absteigen von dem Laufrad wird die Verriegelung 24 wieder gelöst, der Sattel 18 schwenkt sich nach unten ab, wobei der Hinterbau 12 sich wieder an den Vorderbau 16 annähert.To get off the wheel, the lock 24 is released again, the saddle 18 swings downward, the rear end 12 again approaching the front end 16 .
Das so gebildete Laufrad kann einfach transportiert werden, in dem eingeschwenkten Zustand ist der Platzbe darf ausgesprochen gering.The impeller thus formed can be easily transported in the swiveled-in state is the Platzbe may be extremely low.
