Abstract

Ziel der Erfindung ist es, eine Seitenstuetze fuer Kraftraeder zu entwickeln, die bei einfacher Bauart eine hohe Funktionssicherheit gewaehrleistet sowie im Park- und Fahrbetrieb keine Unfallquelle darstellt. Die Aufgabe der Erfindung besteht in der Entwicklung einer manuell in die Parkstellung ausschwenkbaren Seitenstuetze fuer Kraftraeder, die durch seitliches Abkippen des Kraftrades verriegelt und Kraft fuer das Entriegeln speichert. Das Entriegeln des Stuetzfusses sowie dessen Schwenk zurueck in die Fahrstellung sollen selbsttaetig beim Rueckfuehren des Kraftrades in die senkrechte Gebrauchslage erfolgen. Erfindungsgemaess wird die Aufgabe dadurch geloest, dass der Stuetzfuss aus einer beidseitig offenen Fuehrungshuelse mit einer darin federnd aufgenommenen Stuetze besteht. Die Fuehrungshuelse wird von einem mit zwei Freiheitsgraden ausgestatteten Drehgelenk getragen, das auf einer ueblichen Grundplatte befestigt ist. Drehgelenkseitig fungiert das austretende Ende der Stuetze als Riegelzapfen, dem ein Verriegelungsanschlag auf der Grundplatte zugeordnet ist. Fig. 2The aim of the invention is to develop a Seitenstuetze for Kraftraeder, which guarantees a high level of reliability in a simple design and is no accident source in parking and driving. The object of the invention is to develop a manually pivotable in the parking position Seitenstuetze for motorcycles, which locks by lateral tilting of the motorcycle and stores power for unlocking. The unlocking of the Stuetzfusses and its pivot back into the driving position should be carried out automatically when returning the motorcycle in the vertical position of use. According to the invention, the object is achieved in that the support foot consists of a guide sleeve open on both sides with a support resiliently received therein. The guide sleeve is supported by a two degrees of freedom pivot, which is mounted on a common base plate. On the hinge side, the emerging end of the supports acts as a locking pin, which is associated with a locking stop on the base plate. Fig. 2

Description

Drehgelenks 9 wirkt. Während die eine Kraftkomponente stets versucht den Stützfuß bis zum Anschlag 8 in die Fahrstellung zu schwenken, hält die andere Kraftkomponente den Stützfuß im unbelasteten Zustand so, daß seine Führungshülse 1 unterhalb der Gelenkebene an der Grundplatte 3 anliegt, also der Winkel α seinen kleinsten Wert hat. Dazu ist die Zugfeder 6 auf der der Längsmittelebene des Kraftrades zugewandten Seite der Seitenstütze angebracht. Die Funktion der Seitenstütze ist wie folgt:·Swivel joint 9 acts. While one force component always tries to pivot the support leg up to the stop 8 in the driving position, the other force component keeps the support leg in the unloaded state so that its guide sleeve 1 rests below the joint plane on the base plate 3, so the angle α has its smallest value , For this purpose, the tension spring 6 is mounted on the longitudinal center plane of the motorcycle facing side of the side support. The function of the side support is as follows:

Zum Abstellen des Kraftrades mittels Seitenstütze schwenkt der Fahrer zunächst die in der Führungshülse 1 gelagerte Stütze 2 aus der Fahrstellung vom Anschlag 8 gegen den Anschlag 7 in die Parkstellung, wobei er die Kraft der Zugfeder 6 überwindet. Bei senkrechter Stellung des Kraftrades erreicht das untere Ende der Stütze 2 den Boden nicht (Figur 1 und 2). Diese Position wird manuell so lange gehalten, bis das Kraftrad seitlich abgekippt wurde, wodurch sich die Seitenstütze selbsttätig verriegelt. Während des Abkippvorganges erreicht das untere Ende der Stütze 2 den Boden und verharrt dort auch bei weiterem Abkippen. Gleichzeitig verschiebt sich die Stütze 2 gegen die Kraft der vorgespannten Druckfeder 11 bis der Anschlag 12 die Führungshülse 1 erreicht. Nun ragt der Riegelzapfen 4 vollständig aus dem oberen Ende der Führungshülse 1 heraus, dem der Verriegelungsanschlag 5 zugeordnet ist. Damit wird sicher gewährleistet, daß der durch den Gelenkzapfen 10 gegebene Freiheitsgrad des Drehgelenks 9 für jede Dreh richtung blockiert ist, solange sich das Kraftrad in der geneigten Parkstellung gemäß Figur 3 befindet.To park the motorcycle by means of side support, the driver first pivots the support 2 mounted in the guide sleeve 1 from the driving position from the stop 8 against the stop 7 in the parking position, wherein it overcomes the force of the tension spring 6. When the motorcycle is in a vertical position, the lower end of the support 2 does not reach the ground (FIGS. 1 and 2). This position is manually held until the motorcycle has been tipped sideways, causing the side support to lock automatically. During the Abkippvorganges the lower end of the support 2 reaches the ground and remains there on further tipping. At the same time, the support 2 shifts against the force of the prestressed compression spring 11 until the stop 12 reaches the guide sleeve 1. Now the locking pin 4 protrudes completely out of the upper end of the guide sleeve 1, which is associated with the locking stopper 5. This ensures that the given by the pivot pin 10 degree of freedom of the rotary joint 9 is blocked for each direction of rotation, as long as the motorcycle is in the inclined parking position according to Figure 3.

Der Winkel α zwischen der Längsmittelebene des Kraftrades und der Längsachse vergrößert sich durch den Drehfreiheitsgrad, welcher über die Zapfen 13 gegeben ist, bis zum Winkel β geringfügig, ohne dabei den Abstellvorgang durch Gleiten des unteren Endes der Stütze 2 auf der Abstellfläche zu behindern.The angle α between the longitudinal center plane of the motorcycle and the longitudinal axis increases by the rotational degree of freedom, which is given over the pins 13, slightly up to the angle β , without hindering the shutdown by sliding the lower end of the support 2 on the shelf.

Vor Fahrtantritt richtet der Fahrer das seitlich abgekippte Kraftrad lediglich auf. Die Kraft der gespannten Druckfeder 11 schiebt die Stütze 2 in der Führungshülse 1 nach unten; der Riegelzapfen 4alsobererTeil der Stütze 2 zieht sich dabei zwangsweise in die Führungshülse 1 zurück. Der Verriegelungsanschlag 5 wird damit wirkungslos, ebenso die oben beschriebene Winkeländerung zwischen Längsmittelebene des Kraftrades und der Längsachse des Stützfußes. Die gespannte Zugfeder 6zieht die freigegebene Führungshülse 1 in die etwa waagerechte Fahrstellung bis zum Anschlag 8 ohne weiteres Mitwirken des Fahrers selbsttätig zurück. Mögliches unbeabsichtigtes Belassen der Seitenstütze in Parkstellung bei Fahrtantritt und damit eine unfallträchtige Situation sind ausgeschlossen.Before driving, the driver merely straightens the side-tipped motorcycle. The force of the tensioned compression spring 11 pushes the support 2 in the guide sleeve 1 downwards; the locking pin 4 alsoberer part of the support 2 forcibly retracts into the guide sleeve 1. The locking stop 5 is thus ineffective, as well as the angle change described above between the longitudinal center plane of the motorcycle and the longitudinal axis of the support foot. The tensioned tension spring 6 pulls the released guide sleeve 1 in the approximately horizontal driving position to the stop 8 without further involvement of the driver automatically back. Possible unintentional leaving the side support in parking position when driving and thus a accident-prone situation are excluded.

Field of application of the invention

The invention relates to a side support for motorcycles, which is hinged to the frame of the motorcycle and swung against the action of a spring from the retracted driving position and held securely by the weight of the dumped motorcycle in parking position.

Characteristic of the known technical solutions

The side support shown in DE-PS 3016865 C1 must touch the ground already at still vertical motorcycle when manually swinging out of the folded driving position with her foot. The final pivoting into the parking position of the side support on the dead position of the two springs is possible only with ground contact; as well as the manual pivoting back of the side support in driving position. At the same time, the side support must be pushed laterally away from the solvent level of the motorcycle at the lateral tilting of the motorcycle until reaching the Endkipplage. Both circumstances, the constant contact with the ground and the lateral pushing away of the side support will complicate the safe parking of the motorcycle, especially in uneven footprint, so that multiple maneuvering may be required. Furthermore, the non-locked side support described here in the direction of travel down parked motorcycle can not prevent the independent pivoting of the side support by Hangabtriebkraft and thus damaging the motorcycle. Similar effects can be caused by bumps in actually flat parking areas.

There are other devices known {eg DE-AS 2453870 and DE-OS 2718982), which return an optionally forgotten by the driver in parking position side support in the driving position. However, these are technically complex and only costly feasible.

Object of the invention

The aim of the invention is to provide a cost-effective, low-maintenance and functionally reliable side support for motorcycles, which is an accident source neither in park or while driving.

Explanation of the essence of the invention

The object of the invention is to develop a manually pivotable in the parking position side support for motorcycles, which locks by lateral tilting of the motorcycle and stores power for unlocking. The unlocking of the support leg and its Schwenkzurück in the driving position should be done automatically when returning the motorcycle in the vertical position of use.

According to the invention the object is achieved in that the support leg consists of a guide sleeve open on both sides with a resiliently received therein support. The guide sleeve is supported by a two-degree-of-freedom pivot mounted on a common base plate. On the hinge side, the emerging end of the support acts as a locking pin, which is associated with a locking stop on the base plate.

embodiment

The invention will be explained in more detail using an exemplary embodiment and the figures. They show:

Figure 1: unlocked side support in park position

FIG. 2: side view of FIG. 1

Figure 3: locked side support in park position

The side support according to the invention is usually mounted by means of a base plate 3 on the frame of my motorcycle. According to the variant illustrated in FIGS. 1 to 3, the rotary joint 9, which is equipped with two degrees of freedom, is rotatably connected to the base plate 3 via the pivot pin 10. The second degree of freedom of the rotary joint 9 is realized by the pins 13 which carry the guide sleeve 1. Therein, the support 2, over which a compression spring 11 is arranged against the force thereof to the stop 12 received axially displaceable. Below the joint plane is the conventional stop for parking position 7, while above a locking stop 5 is provided, which corresponds to the parking position according to Figure 3, ie at maximum pushed through the guide sleeve 1 support 2, with the locking pin 4. The tension spring 6 is fixed between the base plate 3 and the guide sleeve 1 so that they always on both degrees of freedom
