"Ausfahrbare-Stoßstange" für Kraftfahrzeuge zur Minderung und Vermeidung von Auffahrunfällen."Extendable bumper" for motor vehicles to reduce and prevent rear-end collisions.
Im weiteren Schreiben "Ausfahrstoßstange" genannt.In the following text referred to as "extension bumper".
Die täglich passierenden Auffahr-Unfalle fordern Leben, Gesundheit und verursachen große Sachschäden. Meines Wissens gibt es bis dato keine Vorrichtung, welche die Stoßkräfte beim Zusammenstoß zweier Fahrzeuge, außerhalb des Fahrzeuges, im Entstehungsmoment aufnimmt und die Knautschwirkung erheblich mindert oder ganz aufhebt.The rear-end collisions that occur every day claim lives, health and cause major material damage. To my knowledge, there is currently no device that absorbs the impact forces when two vehicles collide, outside the vehicle, at the moment they occur and significantly reduces or completely eliminates the crumple effect.
Die hier beschriebene Erfindung, "Ausfahrstoßstange" mindert, oder hebt bei leichter Kollision, Auffahrunfälle ganz auf.The invention described here, the "extending bumper", reduces or even completely eliminates rear-end collisions in the case of minor collisions.
Aufbau:Construction:
Die "Ausfahrstoßstange" besteht aus der Profilstahl-Montageschiene (1) der eigentlichen "Ausfahrstoßstange" (2) die Flanschen gegeneinander gerichtet, so daß ein quadratischer oder rechteckiger Hohlraum entsteht.The "extension bumper" consists of the profile steel mounting rail (1) of the actual "extension bumper" (2) with the flanges facing each other so that a square or rectangular cavity is created.
In diesem Hohlraum sind 2 Doppel-Gelenkarme (3-4), Stoß-Zug-Dämpfer (5), Zweifach-Verriegelung (6), Einzugsmechanik (7) mit Wickelbänder (8), Diametralstange (12), und 6 Schenkelfedern (17) eingebaut.In this cavity, 2 double-joint arms (3-4), shock absorbers (5), double locking (6), retraction mechanism (7) with winding straps (8), diametrical rod (12), and 6 leg springs (17) are installed.
Die Ausfahrarme (3-4) bilden über die 3, bzw. 6 Scharniere (9-10-11) Gelenke und verbinden Montageschiene (1) mit Ausfahrstoßstange (2) . Die Achsbolzen der 6 Scharniere dienen zugleich zur Aufnahme der 6 starken, vorgespannten Schenkelfedern (17) welche die Ausfahrstoßstange (2) nach Auslösung der Verriegelung (6) die über Bautenzug, Gestänge, oder hydraulisch mit der Fußbremse verbunden ist und nur bei einer Vollbremsung die Verriegelung in Stellung d, Fig. 2 bringt. Dadurch können die 6 Schenkelfedern in Aktion treten und die Ausfahrstoßstange (2) in einem Bruchteil einer Sekunde, in die ausgefahrene Einsatzstellung von (a) nachThe extension arms (3-4) form joints via the 3 or 6 hinges (9-10-11) and connect the mounting rail (1) with the extension bumper (2). The axle bolts of the 6 hinges also serve to accommodate the 6 strong, pre-tensioned leg springs (17) which the extension bumper (2) is held in place after the locking mechanism (6) is triggered, which is connected to the foot brake via a cable, rods or hydraulically and only brings the locking mechanism into position d, Fig. 2 in the event of an emergency stop. This allows the 6 leg springs to come into action and the extension bumper (2) can be moved into the extended operating position from (a) to (b) in a fraction of a second.
(b) bringen.(b) bring.
Die Scharniere (9-10-11) welche die Ausfahrarme (3-4) verbinden, sind so gestaltet, daß ein Knickwinkel (c) durch Zusammentreffen der Profilrücken erhalten bleibt, der beim Aufprall das Ausschwenkmoment der Ausfahrarme (3-4) garantiert.The hinges (9-10-11) which connect the extension arms (3-4) are designed in such a way that a bending angle (c) is maintained by the meeting of the profile backs, which guarantees the pivoting moment of the extension arms (3-4) in the event of an impact.
Der justierte Stoß-Zug-Dämpfer (5) und die 6 Schenkelfedern (9-10-11) bewirken im Zusammenwirken nur ein sehr gedämpftes Zurückweichen der Ausfahrstoßstange (2) wodurch der Aufprall optimal gedämpft- und das Unfallausmaß erheblich gemindert, wenn nicht ganz aufgehoben wird.The adjusted shock-tension damper (5) and the 6 leg springs (9-10-11) work together to cause only a very dampened retreat of the extension bumper (2), which optimally dampens the impact and significantly reduces, if not completely eliminates, the extent of the accident.
Der Einzug der ausgefahrenen Ausfahrstoßstange (2) kann von Hand mittels Kurbel, elektrisch oder hydraulisch, je nach Wagentyp, geschehen. Im vorliegenden Fall ist Handeinzug vorgesehen. Über eine Welle mit Vierkant (7) wird an 2 Stellen (8) ein Zug-Wickelband das an der Ausfahrstoßstange (2) befestigt ist, aufgewickelt, die Ausfahrstoßstange (2) eingezogen, wodurch die 2 Riegel (6) über die 2 Riegelbolzen (14) Fig. 2 einrasten und die Ausfahrstoßstange einsatzbereit festhält.The extended bumper (2) can be retracted manually using a crank, electrically or hydraulically, depending on the type of vehicle. In this case, manual retraction is provided. A tension winding tape that is attached to the bumper (2) is wound up at two points (8) via a square shaft (7), the bumper (2) is retracted, whereby the two latches (6) engage via the two latch bolts (14) Fig. 2 and the bumper is held in place ready for use.
Die Diametralstabilisierstange (12) stabilisiert den Ausfahrvorgang .The diametrical stabilizing rod (12) stabilizes the extension process.
