Description
Fahrrad. Die Erfindung bezieht sich auf ein Fahr rad, welches sich besonders als Renner eignet und sich dadurch auszeichnet, dass es zwecks Verringerung des Luft- bezw. Fahrwiderstan des zum Fahren in der Bauchlage des Kör pers eingerichtet ist.
Die beiliegende Zeichnung veranschaulicht ein Ausführungsbeispiel des Erfindungs gegenstandes.
F'ig. 1 zeigt das Rad in Seitenansicht und Fig. 2 in Draufsicht.
Das beispielsweise dargestellte Fahrrad besitzt ein gegenüber dem Hinterrad 1 kleine res Vorderrad 2; an dessen Gabel 3 ist die Lenkstange 4 derart vertieft angeordnet, dass die Griffe 5 sich annähernd auf der Höhe der Vorderradachse befinden (Fig. 1).
Der obere Träger 6 des Fahrzeugrahmens besteht aus zwei parallelen, durch Verstre bungen 7 miteinander starr verbundenen Stangen (Fig. 2), auf denen Querleisten 8 und 9 befestigbar und längsverstellbar aufliegen, auf denen Körperstützen 10, 10a und 11, 11cz befestigbar und verstellbar sind. Die Stützen 10, 10a dienen als Bruststützen und die Stüt zen 11, 11a als Hüftstützen.
Durch die Ver- stellbarkeit der Querleisten und der Stützen können letztere den verschiedenen Körperfor men des Fahrers angepasst werden. a Der Träger 6 des Fahrzeugrahmens ist über das Hinterrad 1 hinaus verlängert und dort bis auf die Höhe der Hinterradachse nach unten gebogen, scharf abgekröpft und mit einem Arm 6a wieder nach vorn geführt. In der Abkröpfung des Trägers 6 hinter dem Hinterrad 1 ist die Nabe 12 der Pedale 13 befestigt. Am Ende des Trägerarmes 6a ist das Lager 14 für die Hinterradachse 15 ange bracht.
Vom Ende des Trägerarmes 6a, der mit den übrigen Verstrebungen des Rahmens ver bunden ist, führt eine Verstrebungsstange 16 zum Träger 6, die nach oben verlängert ist, wo sie zusammen mit einer zur Abkröpfung des Trägers 6 führenden Stange 17 eine waagrecht angeordnete Muffe 18 für einen Sattel 19 trägt. Die Wirkungs- und Fahrweise des Fahr rades ergibt sich ohne weiteres aus Fig. l , ivo ein Fahrer strichpunktiert in der Fahr stellung eingezeichnet ist.
Der Fahrer findet: die zum Treten der Pedale 13 nötigen Gegen stützen in den Stützen 10, 10a bezw. 11, 11a, auf denen er mit der Brust bezw. den Hüften aufliegt.
Durch die Fahrstellung in der Bauchlabe wird gegenüber der bisherigen Sitzlage eine bedeutende Herabminderung des Fahr- bezw. Luftwiderstandes erzielt, was besonders beim Rennfahren von wesentlichem Vorteil für di Fahrgeschwindigkeit ist.
Bicycle. The invention relates to a bicycle, which is particularly suitable as a racer and is characterized by the fact that it BEZW for the purpose of reducing the air. Driving resistance is set up for driving in the prone position of the body.
The accompanying drawing illustrates an embodiment of the subject invention.
F'ig. 1 shows the wheel in side view and FIG. 2 in plan view.
The bicycle shown for example has a relative to the rear wheel 1 small res front wheel 2; on its fork 3, the handlebar 4 is recessed in such a way that the handles 5 are approximately at the level of the front wheel axle (FIG. 1).
The upper support 6 of the vehicle frame consists of two parallel rods rigidly connected to one another by struts 7 (Fig. 2), on which cross bars 8 and 9 are fastened and longitudinally adjustable, on which body supports 10, 10a and 11, 11cz can be fastened and adjusted . The supports 10, 10a serve as chest supports and the supports 11, 11a as hip supports.
The adjustability of the cross bars and the supports means that the latter can be adapted to the different body shapes of the driver. a The carrier 6 of the vehicle frame is extended beyond the rear wheel 1 and there bent down to the level of the rear wheel axle, bent sharply and guided forward again with an arm 6a. The hub 12 of the pedals 13 is fastened in the bend of the carrier 6 behind the rear wheel 1. At the end of the support arm 6a, the bearing 14 for the rear wheel axle 15 is introduced.
From the end of the support arm 6a, which is connected to the other struts of the frame, a strut rod 16 leads to the carrier 6, which is extended upward, where it together with a leading to the bend of the carrier 6 rod 17 has a horizontally arranged sleeve 18 for carries a saddle 19. The mode of operation and driving of the bicycle is readily apparent from Fig. 1, ivo a driver is shown in phantom in the driving position.
The driver finds: the necessary to step on the pedals 13 counter support in the supports 10, 10a respectively. 11, 11a, on which he resp. rests on the hips.
Due to the driving position in the abdomen, compared to the previous sitting position, a significant reduction in driving and / or driving position is achieved. Achieved air resistance, which is of particular advantage for the driving speed when racing.
