Die Erfindung bezieht sich auf eine zum Öffnen einer Tür, insbesondere einer Kraftfahrzeugtür, bestimmte, vom Türschloß räumlich entfernt liegende, einen Handgriff aufweisende Vorrichtung, die beim Schließen der Tür diese mechanisch verriegelt und ein unbeabsichtigtes öffnen der Tür dadurch verhindert, daß der Handgriff zunächst einen vom Hub des an die Schloßfalle angehängten Gestänges unabhängigen Hub ausführen muß, bevor das Gestänge bewegt wird.The invention relates to a particular for opening a door, in particular a motor vehicle door, from the door lock spatially remote, a handle having device that when Closing the door this is mechanically locked and prevents the door from being opened unintentionally, that the handle is initially independent of the stroke of the linkage attached to the lock latch Must perform stroke before the linkage is moved.

Es ist eine derartige Sicherungsvorrichtung an Autotüren bekannt, bei welcher der Handgriff zunächst eine zur Bewegungsrichtung des Türriegels senkrechte Bewegung gegen Federwirkung ausführen muß, bevor er den Riegel betätigen kann. Eine solche unterschiedliche Bewegungsrichtung des Handgriffes bedeutet jedoch eine Erschwernis beim Öffnen der Tür, zumal sich der Griff bei einem axialen Hineindrücken oder Herausziehen leicht verklemmen kann. Es sind des weiteren Verriegelungsvorrichtungen für Türen bekannt, bei denen die Verriegelung wahlweise auf zwei Arten vorgenommen werden kann. Hierbei ist entweder der innere Türhandgriff auf den Verriegelungsbolzen wirksam, ohne daß dieser durch den äußeren Druckknopf bzw. Handgriff beeinflußt wird, oder aber die Einwirkung des Türhandgriffes auf den Riegelbolzen wird unterbrochen.Such a safety device is known on car doors, in which the handle initially execute a movement perpendicular to the direction of movement of the door bolt against the action of the spring must before he can operate the latch. Such a different direction of movement of the handle However, it means a difficulty when opening the door, especially since the handle is pushed in axially jamming or pulling out. There are also locking devices for Known doors in which the locking can be made optionally in two ways. Here either the inner door handle is effective on the locking bolt without this through the outer push button or handle is influenced, or the action of the door handle on the The locking bolt is interrupted.

Bei einer anderen bekannten Ausführung kann die Türfalle unabhängig von der Innen- oder von der Außenseite der Tür her betätigt werden. So kann sich die Falle beim Betätigen eines Türgriffes unabhängig von einer mit dem Griff formschlüssig verbundenen Kurbel bewegen. Die Falle wird hierbei von dem Türgriff über dessen ganzen Hub zwangläufig zum Entriegeln der Tür mitgenommen, ohne daß ein Spiel in der Betätigungsbewegung vorgesehen ist.In another known embodiment, the door latch can be independent of the interior or of the Outside of the door can be operated. In this way, the trap can operate independently when a door handle is operated move by a crank positively connected to the handle. The trap is here of the Door handle over its entire stroke inevitably taken to unlock the door without a game is provided in the actuation movement.

Die Erfindung bezweckt demgegenüber eine Sicherungsvorrichtung, welche trotz einfachster Mittel mit der erforderlichen Sicherheit ein bequemes Bedienen der Tür zum Entriegeln und Öffnen derselben gestattet. Sie besteht im wesentlichen darin, daß der Handgriff als ein um eine vorzugsweise lotrechte Achse schwenkbarer Hebelarm ausgebildet ist und mit einem um die gleiche Achse schwenkbaren, mit dem Gestänge für die Schloß falle verbundenen Hebelarm kniehebelartig mit Spiel in Schwenkrichtung mittels Mitnehmern zusammenwirkt und durch eine Rückstellkraft, z. B. die Kraft einer Feder, in eine durch einen Anschlag des Handgriffes bestimmte Ruhelage gedrängt wird, wobei die Mitnehmer entsprechend dem vorhandenen Spiel voneinander entfernt sind, so daß beim Schwenken des Handgriffes in Öffnungsrichtung dieser zunächst einen dem Spiel entsprechenden Leerhub ausführt und erst hierauf nach dem Vorrichtung zum öffnen einer Tür, insbesondere einer KraftfahrzeugtürThe invention aims at a safety device, which despite the simplest means with the required security allows convenient operation of the door to unlock and open the same. It consists essentially in the fact that the handle as a preferably perpendicular Axis pivotable lever arm is formed and with a pivotable about the same axis with the linkage for the lock case connected lever arm toggle-like with play in the pivoting direction means Drivers cooperate and by a restoring force, z. B. the force of a spring into a through a stop of the handle certain rest position is pushed, with the driver accordingly the existing game are removed from each other, so that when pivoting the handle in the opening direction this first executes an idle stroke corresponding to the game and only then after Device for opening a door, in particular a motor vehicle door

Anlegen der beiden Mitnehmer aneinander im gleichen Schwenkhub das die Türfalle betätigende Gestänge mitnimmt. Die Ausführung des Leerhubes und das Entriegeln bzw. Öffnen der Tür erfolgt also in einem einzigen entsprechend unterteilten Bewegungshub. Die Bedienung ist dadurch, insbesondere in Verbindung mit der schwenkbaren Lagerung des Bedienungsorgans, außerordentlich einfach, störungsfrei und bietet infolge des vorgeschalteten federnden Leerhubes trotzdem die erforderliche Sicherheit gegen ein unbeabsichtigtes Entriegeln und öffnen der Tür.Apply the two drivers to each other in the same swivel stroke the linkage actuating the door latch takes away. The execution of the idle stroke and the unlocking or opening of the door is done in one single correspondingly subdivided movement stroke. The operation is thereby, in particular, in connection with the pivoting mounting of the control element, extremely simple, trouble-free and offers as a result the upstream resilient idle stroke still provides the necessary security against an unintentional Unlock and open the door.

In einer besonders einfachen und zweckmäßigen Ausführungsform der Erfindung ist die Nabe des mit dem Gestänge verbundenen Hebelarmes mit einer durchgehenden geraden ersten Mitnehmerfläche und die Nabe des gleichachsig mit dem Hebelarm gelagerten Handgriff-Hebelarmes mit zwei dem Spiel entsprechend winklig zueinander stehenden Flächen, einer Anschlagsfläche und einer zweiten Mitnehmerfläche, versehen, von denen die Anschlagsfläche in der Ruhelagen an der erstgenannten Mitnehmerfläche anliegt und die zweite Mitnehmerfläche mit der ersten einen spitzen Winkel bildet, derart, daß beim Schwenken des Handgriffes die Mitnahme des Gestänges erst stattfindet, wenn die zweite Mitnehmerfläche des Handgriffes an die erste Mitnehmerfläche des Gestängehebels anschlägt.In a particularly simple and expedient embodiment of the invention, the hub is with the linkage connected lever arm with a continuous straight first driver surface and the hub of the handle lever arm mounted coaxially with the lever arm with two play correspondingly angled surfaces, a stop surface and a second driver surface, provided, of which the stop surface rests in the rest position on the first-mentioned driver surface and the second driver surface forms an acute angle with the first such that when pivoting of the handle the entrainment of the rod only takes place when the second driver surface of the Handle strikes against the first driver surface of the linkage lever.

Claims

An exemplary embodiment of the invention is shown in the drawings, namely: FIG. 1 shows an overall view of the door opening device, FIG. 2 shows the plan view of the opening device in section along line 2-2 of FIG. 3 shows a section along line 3-3 of FIG. 2 with the door closed, FIG. 4 shows the same section as FIG. 2, but in an intermediate position of the door handle, FIG. 5 shows the same section as FIGS. 2 and 4, but in one position the end position of the handle corresponding to the open position of the door, and FIG. 6 shows a section along line 6-6 of FIG. 1 on a larger scale. Fig. 1 shows the door 10, which is articulated with a vertical axis of rotation 11 on the body. The door lock 12 is designed in a manner known per se and contains a door latch 13 which can be opened from the outside by a push button 14. A locking device 15 can be provided in order to lock the lock from the inside in such a way that it cannot be opened from the outside (e.g. when the plunger 15 is pressed down). To open the door from the inside, the linkage 16 is used, which is connected to a lever arm 17 which, together with a second lever arm 18 to be operated by hand, forms the handle. The lever arms 17 and 18 are mounted on the inner wall 19 of the door on a bearing block 20 fastened to the wall by means of screws 20a and 20b by means of a bearing journal 21 so as to be rotatable with respect to one another. The fork ends 17 a and 17 b of the lever arm 17 encompass the hub 22 of the lever arm 18. In the hub 22, a circular section-shaped recess 23 is provided which encloses the pin 21 with play. A hairpin spring 24 is interposed between the wall of the recess 23 and the pin 21. One end of the spring 24 rests against the contact surface 25 formed by the wall of the recess 23, the other end against the first driver surface 26 of the lever arm 17. The hub 22 of the lever arm 18 also has two V-shaped surfaces 27 and 28 which are alternately brought into contact with the driver surface 26 of the lever arm 17 when the lever arm 18 is rotated about the pin 21. A cap 29 provided with a slot for the lever arm 18 can cover the joint on the outside. In Fig. 2, the device consisting of the two lever arms 17 and 18 is shown in a position corresponding to the closed position of the door. The linkage 16 is pulled to the right by the lock spring arranged in the lock 12, while the spring 24 continues to adjust the manually operated lever arm 18 clockwise until the stop surface 27 of the lever arm 18 rests on the driver surface 26 of the lever arm 17 and the lever arm 18 comes as close as possible to the inner lining of the body 19, but leaves so much space free that it can still be comfortably operated by hand. To open the door, the lever arm 18 is pivoted about the pin 21 in the direction of the arrow χ. Since the tension of the small spring 24 is significantly less than that of the lock spring, the lever arm 17 remains at rest in accordance with the play that exists between the second driver surface 28 on the lever arm 18 and the first driver surface 26 on the lever arm 17. Only after the position according to FIG. 4 has been exceeded, in which the second driver surface 28 rests against the first driver surface 26, the lever arm 17 is taken along when the lever arm 18 is moved further in the direction of arrow χ by coupling the two lever arms to one another in the manner of a knee joint. The linkage 16 is adjusted to the left in the direction of the arrow y, thereby opening the door. In Fig. 5, the extreme position of the handle is shown with the door open. By adjusting the linkage 16, the locking device 15 can also be unlocked at the same time, provided that it was previously in the locking position. On the basis of the above explanations, an explanation of FIG. 6, which shows the device in the rest position and on an enlarged scale, can be dispensed with. Patent claims:
