Dabei wird der Stift 6 durch das lageveränderbare Element in den Puffer 3 gedrückt. Nun wird das lageveränderbare Element wieder geöffnet und mittels eines geeigneten Messinstrumentes der Abstand zwischen der Oberkante der Aufnahmehülse 2 und der Oberkante des Kopfteiles des Stiftes 6 gemessen. Der Stift 6 wird dann entfernt und der Puffer 3 soweit aus der Aufnahmehülse 2 herausgedreht, dass der vorher gemessene Abstand - ergänzt um ein vorgegebenes Vorspaπnungsmaß von beispielsweise 5/10 mm - nunmehr zwischen der Oberkante der Aufnahmehülse 2 und der Oberkante des Puffers 3 eingestellt ist.In the Aniieferzustand the pin 6 is over the buffer 3 on that results in a distance between the lower edge of the plate-like head portion and the upper edge of the buffer 3. The thus prepared stop buffer 1 is then inserted, for example, in an opening in the vehicle body. Then the iageverbarerbare element is carefully closed until it locks into a lock, for example. In this case, the pin 6 is pressed by the position-variable element in the buffer 3. Now the position-variable element is opened again and by means of a suitable Measuring the distance between the upper edge of the receiving sleeve 2 and the upper edge of the head portion of the pin 6 measured. The pin 6 is then removed and the buffer 3 as far removed from the receiving sleeve 2, that the previously measured distance - supplemented by a predetermined Vorspaπnungsmaß of example 5/10 mm - is now set between the upper edge of the receiving sleeve 2 and the upper edge of the buffer 3 ,
Zur schnellen Einstellung der Höhe des Puffers 3 ist dieser auf seiner gesamten Länge mit einer Markierung versehen, welche mit Markierungen an der Aufnahmehülse 2 zusammenwirkt, die vorzugsweise an deren oberen freien Rand vorgesehen sind. Der Abstand der Markierungen an der Aufnahmehülse 2 entspricht dabei in Abhängigkeit von der Steigung des Gewindes auf der Außenseite des Puffers 3 einem festgelegten Weg beim Verdrehen des Puffers 3. So kann auf einfache Weise das erforderliche Maß eingestellt werden.For rapid adjustment of the height of the buffer 3 this is provided over its entire length with a mark which cooperates with markings on the receiving sleeve 2, which are preferably provided at the upper free edge. The distance between the markings on the receiving sleeve 2 corresponds to a predetermined path when rotating the buffer 3 as a function of the pitch of the thread on the outside of the buffer 3. Thus, the required amount can be adjusted in a simple manner.
Nach einer zweiten, in Figur 2 dargestellten Ausführungsform, wird das verschiebbare Element von einem L-förmigen Büge! 7 gebildet, der an der Aufnahmehülse 2 verschiebbar gelagert ist. Dazu ist die Aufnahmehülse 2 mit einer Führung 8 versehen, welche am Außenumfang der Aufnahme- hülse 2 angeordnet ist. Die Führung 8 nimmt den längeren Schenkel des L-förmigen Bügels 7 auf, und der kürzere Schenkel erstreckt sich in Richtung auf den Puffer 3,According to a second embodiment shown in Figure 2, the displaceable element of an L-shaped strap! 7 formed, which is slidably mounted on the receiving sleeve 2. For this purpose, the receiving sleeve 2 is provided with a guide 8, which is arranged on the outer circumference of the receiving sleeve 2. The guide 8 receives the longer leg of the L-shaped bracket 7, and the shorter leg extends in the direction of the buffer 3,
Die Einstellung des Puffers 3 mit Hilfe des Bügels 7 geht wie folgt vor sich:The adjustment of the buffer 3 by means of the bracket 7 is as follows:
Im Anlieferzustand steht der kürzere Schenkel des L-förmigen Bügels 7 so über den Puffer 3 über, dass sich ein Abstand zwischen der Unterkante des Schenkels und der Oberkante des Puffers 3 ergibt. Der so vorbereitete Anschlagpuffer 1 wird dann beispielsweise in eine Öffnung in der Fahrzeugkarosserie gesteckt. Dann wird das lageveränderbare Element vor- sichtig geschlossen, bis dieses beispielsweise in ein Schioss einrastet Dabei wird der Bügel 7 durch das lageveränderbare Element in der Führung 8 verschoben. Nun wird das lageveränderbare Element wieder geöffnet und der Puffer 3 soweit herausgedreht, bis er an der Unterkante des kürzeren Schenkels des Bügels 7 anliegt. Nunmehr wird der Bügel 7 entfernt. Danach wird der Puffer 3 um ein derartiges Maß weiter herausgedreht, welches der Materiaistärke des Bügels 7 plus dem erforderlichen Vorspannungsmaß (beispielsweise 5/10 mm) entspricht,In the delivery condition, the shorter leg of the L-shaped bracket 7 projects beyond the buffer 3 such that there is a spacing between the lower edge of the leg and the upper edge of the buffer 3. The thus prepared stop buffer 1 is then inserted, for example, in an opening in the vehicle body. Then the position-variable element becomes closed visibly, until this example engages in a Schioss Here, the bracket 7 is displaced by the position variable element in the guide 8. Now the position-variable element is opened again and the buffer 3 is turned out until it rests against the lower edge of the shorter leg of the bracket 7. Now the bracket 7 is removed. Thereafter, the buffer 3 is further unscrewed to such an extent, which corresponds to the material thickness of the bracket 7 plus the required Vorspannungsmaß (for example, 5/10 mm),
Auch bei dieser Ausführungsform ist zur schnellen Einstellung der Höhe des Puffers 3 dieser auf seiner gesamten Länge mit einer Markierung versehen, welche mit Markierungen an der Aufnahmehülse 2 zusammenwirkt, die vorzugsweise an deren oberen freien Rand vorgesehen sind. Der Abstand der Markierungen an der Aufnahmehülse 2 entspricht dabei in Abhängigkeit von der Steigung des Gewindes auf der Außenseite des Puffers 3 einem festgelegten Weg beim Verdrehen des Puffers 3.Also in this embodiment, for rapid adjustment of the height of the buffer 3, this is provided over its entire length with a marking which cooperates with markings on the receiving sleeve 2, which are preferably provided at the upper free edge. The distance between the markings on the receiving sleeve 2 corresponds in dependence on the pitch of the thread on the outside of the buffer 3 a fixed path during rotation of the buffer third
Nach einer dritten, in Figur 3 dargestellten Ausführungsform, wird das verschiebbare Element von einer auf den Puffer 3 aufsetzbaren hülsenförmi- gen und in Achsrichtung des Puffers 3 verschiebbaren Messkappe 9 gebildet, Die Messkappe 9 ist mit einem Fenster 10 versehen, an dessen Rand eine Messskala 11 angeordnet ist.According to a third embodiment shown in FIG. 3, the displaceable element is formed by a sleeve-shaped measuring cap 9 which can be placed on the buffer 3 and displaceable in the axial direction of the buffer 3. The measuring cap 9 is provided with a window 10, at the edge thereof a measuring scale 11 is arranged.
Die Einstellung des Puffers 3 mit Hilfe der Messkappe 9 geht wie folgt vor sich:The setting of the buffer 3 with the aid of the measuring cap 9 is as follows:
Der Anschlagpuffer 1 wird beispielsweise in eine Öffnung in der Fahrzeugkarosserie gesteckt, Dann wird die Messkappe 9 derart auf den Puf- fer 3 gesetzt, dass ein größtmöglicher Freiraum zwischen der Oberkante des Puffers 3 und dem Boden der Messkappe 9 erhalten bleibt. Nunmehr wird das lageveränderbare Element vorsichtig geschlossen, bis dieses beispielsweise in ein Schioss einrastet. Dabei wird die Messkappe 9 durch das lageveränderbare Element auf den Puffer 3 gedrückt. Nun wird das lageveränderbare Element wieder geöffnet. Durch das Fenster 10 in einer Seitenwand der Messkappe 9 ist nun in Verbindung mit der neben dem Fenster 10 angeordneten Messskala 11 ersichtlich, wie weit die Messkap- pe 9 auf dem Puffer 3 aufgeschoben werden ist. Dieser Wert wird abgelesen, Nunmehr wird die Messkappe 9 entfernt und ein Einstellring 12 über den Puffer 3 geschoben. An dem Einstellring 12 sind vorzugsweise an dessen Oberkante Markierungen 13 angebracht, welche mit einer Markierung 14 auf der Oberseite des Puffers 3 zusammenwirken. Der Einstellring 12 wird nun beispielsweise mit Hilfe eines vorzugsweise einstückig angeformten Handgriffs 15 so ausgerichtet, dass eine der Markierungen 13 an dem Einstellring 12 mit der Markierung 14 auf der Oberseite des Puffers 3 übereinstimmt. Nunmehr wird der Puffer 3 durch Herausdrehen aus der Aufnahmehülse 2 entsprechend dem zuvor an der Messkappe 9 abgele- sen Wert plus einem vorgegebenen Vorspannungsmaß von beispielsweise 5/10 mm eingestellt. Während der Einstellung ist sicher zu stellen, dass der Einstellring 12 seine einmal eingestellte Lage nicht verändert.The stop buffer 1 is inserted, for example, into an opening in the vehicle body. Then, the measuring cap 9 is placed on the buffer 3 in such a way that the greatest possible clearance is maintained between the upper edge of the buffer 3 and the bottom of the measuring cap 9. Now, the position-variable element is carefully closed until it snaps into place, for example, in a Schioss. In this case, the measuring cap 9 through pressed the position-variable element on the buffer 3. Now the position-variable element is opened again. Through the window 10 in a side wall of the measuring cap 9, in conjunction with the measuring scale 11 arranged next to the window 10, it can be seen how far the measuring cap 9 is pushed onto the buffer 3. This value is read, now the measuring cap 9 is removed and an adjusting ring 12 is pushed over the buffer 3. On the adjusting ring 12, markings 13 are preferably attached to its upper edge, which cooperate with a marking 14 on the upper side of the buffer 3. The adjusting ring 12 is now aligned for example by means of a preferably integrally molded handle 15 so that one of the marks 13 on the adjusting ring 12 coincides with the mark 14 on the top of the buffer 3. Now, the buffer 3 is adjusted by unscrewing from the receiving sleeve 2 in accordance with the previously read on the measuring cap 9 value plus a predetermined preload of, for example, 5/10 mm. During adjustment, make sure that the adjusting ring 12 does not change its once set position.
Auf den Einstellring 12 kann auch verzichtet werden, wenn die Markierungen 13 an der Anschlaghülse 2, insbes. an deren Oberseite angebracht sind.On the adjustment ring 12 can also be omitted if the markers 13 are attached to the stop sleeve 2, esp. At the top.
Nach einer vierten, in Figur 5 dargestellten Ausführungsform, ist das verschiebbare Element ebenfalls von einer auf den Puffer 3 aufsetzbaren hülsenförmigeπ und in Achsrichtung des Puffers 3 verschiebbaren Messkappe 9 gebildet. Die Messkappe 9 ist an ihrem Innenumfang mit Rastvor- Sprüngen versehen, welche mit Rastvorsprüngen 16 an dem Außenumfang des Puffers 3 zusammenwirken.According to a fourth embodiment shown in FIG. 5, the displaceable element is likewise formed by a sleeve-shaped sleeve 3 which can be placed on the buffer 3 and a measuring cap 9 which can be displaced in the axial direction of the buffer 3. The measuring cap 9 is provided on its inner circumference with Rastvor- jumps which cooperate with latching projections 16 on the outer periphery of the buffer 3.
Die Einstellung des Puffers 3 mit Hilfe dieser Messkappe 9 geht wie folgt vor sieh: Der Anschlagpuffer 1 wird beispielsweise in eine Öffnung in der Fahrzeugkarosserie gesteckt. Dann wird die Messkappe 9 derart auf den Puffer 3 gesetzt, dass ein größtmöglicher Freiraum zwischen der Oberkante des Puffers 3 und dem Boden der Messkappe 9 erhalten bleibt. Nunmehr wird das lageveränderbare Element vorsichtig geschlossen, bis dieses beispielsweise in ein Schloss einrastet. Dabei wird die Messkappe 9 durch das tageveränderbare Element auf den Puffer 3 gedrückt, wobei die Rastvorsprünge am Innenumfang der Messkappe 9 und die Rastvorsprünge 16 am Außenumfang des Puffers 3 solange aneinander entlang gleiten, bis sie eine durch das lageveränderbare Element vorgegebene Endlage erreicht haben. Nun wird das lageveränderbare Element wieder geöffnet. Jetzt muss nur noch das vorgegebene Vorspannungsmaß von beispielsweise 5/10 mm eingestellt werden. Dies geschieht dadurch, dass die Messkappe 9 um den Betrag des vorgegebenen Vorspannungsmaßes wieder nach oben gezogen wird. Besonders einfach lässt sich dies bewerkstelligen, wenn die Rastvorsprünge einen Abstand voneinander haben, welcher dem Vorspannungsmaß, beispielsweise 5/10 mm, entsprichtThe setting of the buffer 3 with the aid of this measuring cap 9 is as follows: The stop buffer 1 is inserted, for example, in an opening in the vehicle body. Then, the measuring cap 9 is placed on the buffer 3 such that the greatest possible space between the upper edge of the buffer 3 and the bottom of the measuring cap 9 is maintained. Now, the position-variable element is carefully closed until it snaps into a lock, for example. In this case, the measuring cap 9 is pressed by the variable-day element on the buffer 3, wherein the locking projections on the inner circumference of the measuring cap 9 and the locking projections 16 on the outer periphery of the buffer 3 as long along slide until they have reached a predetermined by the position variable element end position. Now the position-variable element is opened again. Now only the preset preload of, for example, 5/10 mm has to be set. This happens because the measuring cap 9 is pulled up again by the amount of the predetermined Vorspannungsmaßes. This can be accomplished particularly easily if the latching projections are at a distance from one another, which corresponds to the preload, for example 5/10 mm
Bei allen Ausführungsformen des Anschlagpuffers ist zwischen der Auf- nahmehüise 2 und dem Kragen 4 ist eine Sollbruchsteile vorgesehen, welche einen passiven Fußgängerschutz bildet. Sollte es zu einem Zusammenstoß mit einem Fußgänger kommen, drückt das lagerveränderbare Element, beispielsweise die Motorhaube, den Puffer 3 und die Aufnahmehülse 2 in Richtung auf den Kragen 4. Durch diese Belastung bricht die Verbindung zwischen Aufnahmehülse 2 und Kragen 4 an der zwischen diesen beiden Bauteilen vorgesehenen Sollbruchstelle, Nunmehr kann sie Aufnahmehülse 2 zusammen mit dem Puffer 3 durch den Kragen 4 in Richtung der Rastelemente 5 rutschen, wodurch das lageveränderbare Element eine gewisse Nachgiebigkeit erfährt, die einem passiven Fußgängerschutz dient. Die vorhergehende Beschreibung der vorliegenden Erfindung dient nur zu illustrativen Zwecken und nicht zum Zwecke der Beschränkung der Erfindung. Im Rahmen der Erfindung sind verschiedene Änderungen und Modifikationen möglich, ohne den Umfang der Erfindung sowie ihrer Äqutvaien- te zu verlassen. In all embodiments of the stop buffer, a predetermined breaking part is provided between the receiving recess 2 and the collar 4, which forms a passive pedestrian protection. Should it come to a collision with a pedestrian, the bearing variable element, such as the hood, presses the buffer 3 and the receiving sleeve 2 in the direction of the collar 4. By this load, the connection between receiving sleeve 2 and collar 4 breaks at the between these two Components provided predetermined breaking point, Now they can slip receiving sleeve 2 together with the buffer 3 through the collar 4 in the direction of the locking elements 5, whereby the variable-position element undergoes a certain compliance, which serves a passive pedestrian protection. The foregoing description of the present invention is for illustrative purposes only, and not for the purpose of limiting the invention. Within the scope of the invention, various changes and modifications are possible without departing from the scope of the invention and its Äqutvaien- te.
