Description

Die Erfindung betrifft eine Verschlußvorrichtung für Motorhauben von Kraftfahrzeugen, bei welcher ein den Verschlußhaken tragender, mit einem schraubenförmigen Schlitz ausgestatteter Bolzen im Innern eines die Motorhaubenwand schräg durchsetzenden Stutzens längsverschiebbar ist. Das Wesen der Erfindung besteht darin, daß der den Verschlußhaken tragende, längsverschiebbare BolzenThe invention relates to a locking device for hoods of motor vehicles, in which one carrying the locking hook, equipped with a helical slot Bolt is longitudinally displaceable in the interior of a stub transversely penetrating the hood wall. The essence of the invention consists in the fact that the longitudinally displaceable bolt carrying the locking hook

ίο rohrförmig gestaltet und gegen Drehung gesichert ist und daß in den schraubenförmigen Schlitz dieses Bolzens ein Stift eingreift, der jn den zylindrischen Fortsatz eines in den Stutzen' eingesetzten, drehbaren, aber nicht verschiebbaren Einstellgliedes eingelassen ist. Auf der Zeichnung sind die Abb. 1 und 2 Achsialschnitte durch die Verschlußvorrichtung bei geöffneter bzw. geschlossener Stellung des Hakens.ίο tubular design and secured against rotation is and that in the helical slot of this bolt engages a pin which jn the cylindrical extension of a rotatable, but not inserted, into the socket slidable adjusting member is embedded. On the drawing are Figs. 1 and 2 Axial sections through the locking device in the open or closed position of the hook.

ao Die Motorhaubenwand 1 besitzt eine Öffnung zur Aufnahme des schräg gerichteten Stutzens 5, der durch die Haubenwand hindurchreicht. Im Innern des Stutzens ist ein rohrförmig gestalteter Bolzen 13 längsverschiebbar gelagert und gegen Drehung gesichert. Er trägt an seinem unteren Ende den Verschlußhaken 4, der den Zweck hat, mit diem Steg 3 eines Bügels 2 zusammenzuwirken, welcher im Innern der Haube angeordnet ist.ao The hood wall 1 has an opening for receiving the obliquely directed nozzle 5, which extends through the hood wall. In the interior of the connecting piece, a tubular bolt 13 is mounted so as to be longitudinally displaceable and secured against rotation. It carries the locking hook 4 at its lower end, which has the purpose of making one with the bridge 3 Cooperate bracket 2, which is arranged inside the hood.

Der Bolzen 13 besitzt zwei Schlitze 14, die einander gegenüberliegen und deren Längsachse parallel zur Achse des Stutzens 5 verläuft. Ein Querbolzen 15 ist in dem Stutzen S befestigt und durchdringt Schlitze 14. Er dient dazu, einen Kolben 16 in seiner Stellung zu erhalten, der sich im Innern des rohrförmigen Bolzens 13 befindet. Am oberen Ende dieses Bolzens ist ein schraubenförmiger Schlitz 17 vorgesehen, in den ein an dem zylindrischen Fortsatz 19 des Einstellgliedes 8 sitzender Stift 18 eingreift. Der Fortsatz 19 besitzt einen Bund 20, der sich gegen einenThe bolt 13 has two slots 14 which are opposite one another and the longitudinal axis of which runs parallel to the axis of the connecting piece 5. A cross bolt 15 is in the socket S. fastens and penetrates slots 14. It serves to maintain a piston 16 in position inside the tubular Bolt 13 is located. At the top of this bolt is a helical one Slot 17 is provided, in which a on the cylindrical extension 19 of the adjusting member 8 seated pin 18 engages. The extension 19 has a federal government 20, which is against a

inwardly directed projection of the connecting piece 5 sets. A coil spring 21 located inside the bolt 13 is supported on the one hand against the piston 16 and on the other hand against the. cylindrical extension 19. The operation of the locking device is as follows: In the position of the parts shown in Fig. 1, the hood is locked. For the purpose of opening xo, the adjusting member 8 is rotated counterclockwise, the pin 18 sliding in the helical slot 17 of the bolt 13 acting on the bolt in such a way that it moves it downwards because the through the. Cross bolt 15 guided bolts cannot rotate. When the pin 18 has reached the upper end of the slot 17, the locking hook 4 has reached the end of the opening collar. If the hook is reversed from the open position according to Fig. 2 into the closed position according to Fig 13 is pulled upwards. At the end of the stroke, the pin 18 lies against the lower end of the slot 17. Here, an incision can be provided into which the pin 18 falls at the end of the locking stroke of the hook in order to secure the hook in its position. A spring 21 arranged between the piston 16 and the cylindrical extension 19 of the adjusting member 8 serves to press the collar of the extension 19 against the projection of the connecting piece 5. F ATENT claims:

1. Closure device for hoods of motor vehicles, in which a the Bolt carrying locking hooks, equipped with a helical slot, inside one of the hood wall is obliquely penetrating connector is longitudinally displaceable, characterized in that the locking hook (4) carrying, longitudinally displaceable bolt (13) is tubular and secured against rotation and that in the helical slot (17) of this bolt (13) a pin (18) engages, which is inserted into the cylindrical extension (19) of one in the nozzle (5), rotatable but not displaceable adjusting member (8) is embedded.

2. Device according to claim 1, characterized in that the adjusting member (8) under the action of a spring (21) whose 'one end is against the extension (19) of the adjusting member (8) and its other end against one inside of the tubular bolt (13) located piston (16) supports the (16) of one in the connecting piece (5), two opposite slots (14) of the tubular Bolt (13) penetrating cross bolt (15) is held.
