Abstract

A stay for the bonnet (2) of a motor vehicle has two gas springs (6, 7), the first, (6), of which has a shorter travel than the second, (7), and its travel is such that it is fully extended when the bonnet (2) is in a first opening position. To take the bonnet (2) to a second position giving virtually free access to the engine compartment (1) it is necessary merely slightly to raise the bonnet (2) to overcome the static friction in the second gas spring (7) and the residual pressure in this gas spring is sufficient to open the bonnet (2) completely. This opening movement is not hampered by the first gas spring since on its cylinder (8) there is a movable casing tube (14) which provides the link between the first gas spring (6) and the hinge (13) on the bonnet (2).

Description

AUFSTELLVORRICHTUNG FÜR DIE MOTOR- ODER KOFFERRAUMHAUBE SET-UP DEVICE FOR THE ENGINE OR TRUNK COVER
Beschreibungdescription
Die Erfindung bezieht sich auf eine AufStellvorrichtung für die Motor- oder Kofferraumhaube eines Kraftfahrzeuges ent¬ sprechend dem Oberbegriff des Anspruchs 1.The invention relates to an installation device for the engine or trunk hood of a motor vehicle according to the preamble of claim 1.
Eine derartige, beispielsweise aus der DE-A 37 18 842 bekannte AufStellvorrichtung hat den Zweck, ein Öffnen der Haube über eine erste oder normale Öffnungsstellung hinaus in eine zweite Öffnungsstellung bringen zu können, die bei¬ spielsweise erforderlich ist, um größere Arbeiten im Motor¬ raum ohne den sonst notwendigen Ausbau der Motorhaube durchführen zu können oder um sperrige Güter transportieren zu können, die bei normal geöffneter Kofferraumhaube nicht untergebracht werden können. Ein Nachteil der bekannten Vorrichtung besteht darin, daß die Haube von Hand von der ersten Öffnungsstellung in die zweite Öffnungsstellung an¬ gehoben werden muß und daß der Benutzer einen Stützhebel entsperren muß, um die zweite Öffnungsstellung der Haube erreichen zu können, in welcher der Stützhebel selbsttätig verriegelt wird. Zum Schließen der Haube muß der Stützhebel wieder manuel entriegelt werden, worauf die Haube in ihrer ersten Öffnungsstellung und durch Zusammendrücken der Gasfedern in ihre Schließstellung gebracht werden kann.Such a stand-up device, known for example from DE-A 37 18 842, has the purpose of being able to bring an opening of the hood beyond a first or normal opening position into a second opening position, which is necessary, for example, for larger work in the engine space without being able to carry out the otherwise necessary removal of the bonnet or to be able to transport bulky goods that cannot be accommodated with the trunk lid normally open. A disadvantage of the known device is that the hood must be lifted by hand from the first open position into the second open position and that the user must unlock a support lever in order to be able to reach the second open position of the hood, in which the support lever automatically is locked. To close the hood, the support lever must be manually unlocked again, whereupon the hood can be brought into its closed position in its first open position and by compressing the gas springs.
Der Erfindung liegt die Aufgabe zugrunde, eine AufStellvor¬ richtung der gattungsgemäßen Art zu schaffen, bei der die Öffnungsbewegung von der ersten in die zweite Öffnungsstel¬ lung weitgehend durch Federkraft erfolgt und eine handbetä¬ tigte Sperr- oder Stützvorrichtung nicht erforderlich ist. Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Patentanspruchs angegebenen Merkmale gelöst.The invention has for its object to provide an opening device of the generic type, in which the opening movement from the first to the second opening position is largely effected by spring force and a manually operated locking or support device is not required. This object is achieved by the features specified in the characterizing part of the patent claim.
Bei dem erfindungsgemäßen Vorschlag wird die Haube nach dem Lösen der Verriegelung durch die kombinierte Kraft der bei¬ den Gasfedern in die erste Öffnungsstellung gebracht, in welcher die erste Gasfeder am Ende ihres Hubs angelangt ist. Die zweite Gasfeder ist allein nicht in der Lage, die Haube aus einer Ruhestellung heraus in die zweite Öffnungs¬ stellung zu bringen. Wenn aber die Haube nur geringfügig von Hand angehoben und damit die Anfangsreibung überwunden wird, so kann die zweite Gasfeder die Haube mit ihrem Resthub in die zweite Öffnungsstellung bringen. Um der ersten Gasfeder diesen zusätzlichen Öffnungsweg zu er¬ möglichen, ist das auf dem Zylinder oder der Kolbenstange dieser ersten Gasfeder verschiebbar angeordnete Mantelrohr vorgesehen, das sich zwischen dieser Gasfeder und einer ihrer Anlenkstellen erstreckt. Ein derartiges Mantelrohr ist an sich aus den DE-A 32 25 974 und 34 33 735 bekannt. Dort ist das Mantelrohr verschiebbar auf dem Zylinder der Gasfeder angeordnet. Der gleiche Effekt wird jedoch er¬ zielt, wenn ein entsprechendes Mantelrohr verschiebbar auf der Kolbenstange angeordnet ist.In the proposal according to the invention, the cover is brought into the first open position after the release of the locking by the combined force of the two gas springs, in which the first gas spring has reached the end of its stroke. The second gas spring alone is not able to bring the hood out of a rest position into the second opening position. However, if the hood is only raised slightly by hand and the initial friction is thus overcome, the second gas spring can bring the hood with its remaining stroke into the second open position. In order to make this additional opening path possible for the first gas spring, the jacket tube which is displaceably arranged on the cylinder or the piston rod of this first gas spring is provided and extends between this gas spring and one of its articulation points. Such a jacket tube is known per se from DE-A 32 25 974 and 34 33 735. There the jacket tube is slidably arranged on the cylinder of the gas spring. The same effect is achieved, however, if a corresponding jacket tube is slidably arranged on the piston rod.
Ein Ausführungsbeipiel der Erfindung wird im folgenden unter Bezugnahme auf die Zeichnungen beschrieben. Es zeigt:An embodiment of the invention is described below with reference to the drawings. It shows:
Fig.l eine perspektivische Ansicht des Vorderteils eines Kraftfahrzeuges mit einer Motorhaube, die in eine erste Öffnungsstellung angehoben ist, undFig.l is a perspective view of the front part of a motor vehicle with a hood, which is raised in a first open position, and
Fig.2 die gleiche Ansicht wie Fig. 1, jedoch mit ganz geöffneter Motorhaube.2 shows the same view as FIG. 1, but with the bonnet fully open.
Das in den Figuren dargestellte Vorderteil eines Kraftfahr¬ zeugs enthält einen Motorraum 1, in welchem der nicht dar- 2 gestellte Antriebsmotor des Kraftfahrzeuges angeordnet ist und der durch eine Motorhaube 2 verschließbar ist. Die Mo¬ torhaube 2 ist über Scharniere 3 schwenkbar an der Karos¬ serie 4 des Kraftfahrzeuges angelenkt. Um nach Lösen einer Verriegelungsvorrichtung, von welcher nur der an der Motor¬ haube 2 angeordnete Fanghaken 5 sichtbar ist, ein selbst¬ tätiges Öffnen der Motorhaube 2 zu erreichen, sind zwei Gasfedern 6 und 7 vorgesehen, die jeweils aus einem mit Druckgas gefüllten Zylinder 8 bzw. 9 und einem darin ver¬ schiebbaren, mit einer Kolbenstange 10 bzw. 11 verbundenen Kolben bestehen. Die Gasfedern 6, 7 sind jeweils zwischen einer Anlenkstelle 12 an der Karosserie 4 und einer Anlenk- stelle 13 an der Motorhaube 2 angeordnet.The front part of a motor vehicle shown in the figures contains an engine compartment 1, in which the not shown 2 provided drive motor of the motor vehicle is arranged and which can be closed by a hood 2. The engine hood 2 is hinged to the body 4 of the motor vehicle via hinges 3. In order to achieve an automatic opening of the bonnet 2 after releasing a locking device, of which only the catch hook 5 arranged on the bonnet 2 is visible, two gas springs 6 and 7 are provided, each of which consists of a cylinder 8 filled with compressed gas or 9 and a piston slidable therein, connected to a piston rod 10 or 11. The gas springs 6, 7 are each arranged between an articulation point 12 on the body 4 and an articulation point 13 on the bonnet 2.
Die erste Gasfeder 6 hat einen kleineren Hub als die zweite Gasfeder 7, und ihr Hub ist so bemessen, daß sie ganz aus¬ gefahren ist, wenn sich die Motorhaube 2 in ihrer ersten, in Fig. 1 gezeigten Öffnungsstellung befindet. Die Motor¬ haube 2 wird durch die kombinierte Kraft der Gasfedern 6 und 7 in diese erste Öffnungsstellung gebracht, in der die zweite Gasfeder 7 noch nicht am Ende ihres Hubes angelangt ist. Ihre Kraft reicht jedoch nicht aus, um die Motorhaube 2 allein in die in Fig. 2 dargestellte volle Öffnungsstel¬ lung zu bringen.The first gas spring 6 has a smaller stroke than the second gas spring 7, and its stroke is dimensioned such that it is fully extended when the bonnet 2 is in its first opening position, shown in FIG. 1. The bonnet 2 is brought into this first opening position by the combined force of the gas springs 6 and 7, in which the second gas spring 7 has not yet reached the end of its stroke. However, their force is not sufficient to bring the bonnet 2 alone into the full opening position shown in FIG. 2.
In der ersten Öffnungsstellung gemäß Fig. 1 können die üb¬ lichen einfachen Wartungsarbeiten, wie Ölstandskontrolle, Ölwechsel, Bremεflüssigkeitskontrolle, Kühlwasserkontrolle usw. ausgeführt werden, die auch häufig von dem Fahrzeug¬ halter selbst durchgeführt werden. In dieser ersten Öff¬ nungsstellung kann die Motorhaube 2 zum Schließen auch von relativ kleinen Personen ergriffen werden. Wenn nun größere Reparaturarbeiten ausgeführt werden sollen, beispielsweise der Motor ausgebaut werden muß, so muß die Motorhaube 2 weiter geöffnet werden. Dies erfolgt durch leichtes Anheben der Motorhaube 2 von Hand, wodurch die statische Reibung insbesondere in der zweiten Gasfeder 7 überwunden wird und die Gasfeder 7 unter dem noch in ihr vorhandenen Gasdruck bis zum Ende ihres Hubes ausgefahren wird, in welcher die Motorhaube 2 die in Fig. 2 dargestellte Lage einnimmt. Die erste Gasfeder 6 trägt zu diesem Öffnungsvorgang nichts bei, da sie, wie gesagt, bereits in der ersten Öffnungs¬ stellung der Motorhaube 2 gemäß Fig. 1 am Ende ihres Hubes angelangt ist. Die weitere Öffnungsbewegung in die volle Öffnungsstellung gemäß Fig. 2 wird von der ersten Gasfeder 6 dadurch nicht behindert, daß zwischen ihrem Zylinder 8 und der Anlenkstelle 13 an der Motorhaube 2 ein Mantelrohr 14 angeordnet ist, das verschiebbar auf dem Zylinder 8 sitzt. Der Zylinder 8 bleibt also in der zweiten Öffnungs¬ stellung der Motorhaube 2 gemäß Fig. 2 in seiner ausgefah¬ renen Stellung und es verschiebt sich lediglich das Mantel¬ rohr 14 auf dem Zylinder 8, wie dies aus Fig. 2 ersichtlich ist.In the first opening position according to FIG. 1, the usual simple maintenance work, such as oil level control, oil change, brake fluid control, cooling water control, etc. can be carried out, which are also often carried out by the vehicle owner himself. In this first opening position, the bonnet 2 can also be gripped by relatively small people for closing. If major repair work is now to be carried out, for example the engine must be removed, the hood 2 must be opened further. This is done by slightly lifting the bonnet 2 by hand, which causes static friction is overcome in particular in the second gas spring 7 and the gas spring 7 is extended under the gas pressure still present in it to the end of its stroke, in which the bonnet 2 assumes the position shown in FIG. 2. The first gas spring 6 does not contribute to this opening process, since, as said, it has already reached the first opening position of the bonnet 2 according to FIG. 1 at the end of its stroke. The further opening movement into the full open position according to FIG. 2 is not hindered by the first gas spring 6 in that a jacket tube 14 is arranged between its cylinder 8 and the articulation point 13 on the bonnet 2, said tube being slidably seated on the cylinder 8. The cylinder 8 thus remains in its extended position in the second opening position of the bonnet 2 according to FIG. 2 and only the jacket tube 14 moves on the cylinder 8, as can be seen from FIG. 2.
Der erfindungsgemäße Vorschlag hat gegenüber dem Stand der Technik den Vorteil, daß die Motorhaube 2 im wesentlichen durch die Restkraft der zweiten Gasfeder 7 aus der ersten Öffnungsstellung gemäß Fig. 1 in die zweite Öffnungsstel¬ lung gemäß Fig. 2 gebracht wird und daß keine manuell zu betätigenden Ver- oder Entriegelungsvorrichtungen erforder¬ lich sind, um die Motorhaube 2 in die zweite Öffnungsstel¬ lung zu bringen, in dieser Öffnungsstellung zu halten und aus dieser Öffnungsstellung wieder zu lösen.The proposal according to the invention has the advantage over the prior art that the bonnet 2 is brought essentially from the first open position according to FIG. 1 into the second open position according to FIG. 2 by the residual force of the second gas spring 7 and that none is closed manually actuating locking or unlocking devices are required to bring the bonnet 2 into the second opening position, to hold it in this opening position and to release it from this opening position.
Die Erfindung ist nicht auf eine Aufstellvorrichtung für die Motorhaube beschränkt, sondern gleichermaßen auch für das Aufstellen der Kofferraumhaube einsetzbar, da auch dort der Wunsch bestehen kann, die Kofferraumhaube im Bedarfs¬ fall weiter öffnen zu können als normal. The invention is not limited to an installation device for the bonnet, but can equally be used for the installation of the trunk hood, since there may also be a desire to be able to open the trunk hood further than normal if necessary.
