Die Erfindung betrifft eine Türschloßsicherung für Kraft wagen tür en, die mit einem von außen durch einen Türgriff und von innen durch einen Gegengriff zu betätigenden Schloß versehen sind, bei dem der innere und der äußere Betätigungsgriff unabhängig voneinander auf ein und denselben Schloßteil einwirken, dessen Verstellung das öffnen der Tür zuläßt.The invention relates to a door lock safety device for motor dare doors with one from the outside by one Door handle and are provided from the inside by a counter-handle to be operated lock, in which the inner and the outer operating handle act independently of one another on one and the same lock part, whose adjustment allows the door to be opened.

Bei derartigen Türschloßsicherungen ist es bereits bekannt, ein Sicherungsglied anzuordnen, das aus einer Außerbetriebsstellung in eine Sicherungsstellung oder umgekehrt verstellbar ist und in seiner Sicherungsstellung verhindert, daß die Tür vom Wageninnern aus geöffnet werfen kann. Die bekannten Schloßsicherungen dieser Art sind aber so ausgebildet, daß sie auf das gesamte Schloß derart einwirken, daß bei eingeschalteter Sicherung nicht nur das öffnen der Tür vom Wageninnern aus, sondern auch das öffnen der Tür von außen verhindert ist. Diese Sicherungen haben daher den schwerwiegenden Nachteil, daß bei Ausfall des Fahrers, z. B. infolge eines Unfalls, bei dem die am Fahrersitz befindliche Tür verklemmt worden ist, die Wageninsassen durch öffnen der übrigen Türen nicht befreit werden können, wenn für diese Türen die Schloß sicherungen eingeschaltet waren.In such door lock fuses, it is already known to arrange a locking member that consists of a Inoperative position is adjustable in a locking position or vice versa and in its locking position prevents the door from inside the car can throw open. The known lock fuses of this type are designed so that they are on the entire lock act in such a way that when the fuse is switched on, not only the opening of the door from Inside the car, but also prevents the door from being opened from the outside. Have these fuses hence the serious disadvantage that if the driver fails, e.g. B. as a result of an accident in which the on The door located in the driver's seat has been jammed, but not the car occupants by opening the other doors can be released if the lock fuses were switched on for these doors.

Zur Beseitigung dieser Nachteile ist es weiterhin bekannt, das als Nocken oder Hebel ausgebildete Sicherungsglied nur dem inneren Türgriff in solcher Anordnung zuzuordnen, daß es ein von diesem Türgriff betätigtes Glied des Schlosses verriegelt, ohne die weitere Öffnungsbewegung des Schloßriegels durch den äußeren Türgriff zu verhindern.To eliminate these disadvantages, it is also known that designed as a cam or lever Fuse link only to be assigned to the inner door handle in such an arrangement that there is one of this door handle actuated member of the lock is locked without further opening movement of the lock bolt to prevent the outside door handle.

Bei einer in dieser Weise ausgebildeten Türschloßsicherung ist es ferner bekanntgeworden, das Sicherungsglied so auszubilden, daß es nur mittels eines Schraubenziehers oder eines ähnlichen Werkzeuges betätigt werden kann, wodurch verhindert werden soll, daß die Tür durch im Wageninnern befindliche Kinder ungewollt geöffnet werden kann. Tatsächlich ist aber eine solche Sicherheit bei der bekannten Ausbildung nicht gewährleistet, da das zum Verstellen des Sicherungsgliedes dienende Glied völlig freiliegt und von jedem Kind, beispielsweise mittels eines Nagelreinigers oder eines Geldstückes od. dgl., betätigt werden kann.In a door lock safety device designed in this way, it has also become known, the safety member to be trained so that it can only be operated by means of a screwdriver or similar tool can be, which is to prevent the door by children inside the car can be opened unintentionally. In fact, however, there is such security in the known training not guaranteed, since the member used to adjust the locking member is completely exposed and from can be operated by any child, for example by means of a nail cleaner or a coin or the like.

Durch die vorliegende Erfindung soll dieser Nachteil dadurch vermieden werden, daß das zum Verstellen des Sicherungsgliedes dienende Glied mit einem Rändel- oder Schlitzkopf versehen ist oder eine Schloßhülse aufweist und an einer derartigen Stelle der Tür angeordnet ist, daß es bei offener Tür freiliegt, bei geschlossener Tür jedoch verdeckt ist oder nur mit dem Kontakt- oder Türschlüssel betätigt werden kann.The present invention is intended to avoid this disadvantage in that the adjustment the locking member serving member is provided with a knurled or slotted head or a lock sleeve and is arranged at such a point on the door that it is exposed when the door is open, when the door is closed However, the door is covered or can only be operated with the contact or door key.

Auf diese Weise ist nunmehr mit voller Sicherheit verhindert, daß die Tür durch im Wageninnern befindliche Kinder unbefugt geöffnet werden kann, da völligIn this way, it is now prevented with full certainty that the door is located in the interior of the car Children can be opened without authorization because completely

ausgeschlossen ist, daß das zum Betätigen des Sicherungsgliedes dienende Glied durch Kinder betätigt werden kann. Denn wenn dieses Glied gemäß der Erfindung so angeordnet ist, daß es bei geschlossener Tür verdeckt ist, so ist überhaupt nicht erreichbar, und wenn es, wie die Erfindung weiterhin vorsieht, nur mit dem Kontakt- oder Türschlüssel zu betätigen ist, so kann es von Kindern nicht unbeabsichtigt verstellt werden, da sie nicht im Besitz des Kontakt- oder Türschlüssels sind.it is excluded that the member used to operate the safety member is operated by children can be. Because if this member is arranged according to the invention so that it is with the door closed is covered, so is not attainable at all, and if it, as the invention further provides, only with is to be operated with the contact or door key so that children cannot unintentionally move it because they do not have the contact or door key.

Nach Fig. 1 bis 3 weist das Türschloß ein Sperrad 1 auf, das gleichachsig und drehfest mit einem äußeren Sperrad 10 verbunden ist. Das Sperrad 10 wirkt mitAccording to FIGS. 1 to 3, the door lock has a ratchet wheel 1 which is coaxially connected to an outer ratchet wheel 10 in a rotationally fixed manner. The ratchet wheel 10 is involved

Claims

a pawl 11 seated on the door frame. To open the door, the ratchet wheel 1 must be released, which is made possible by tilting the pawl 2 . Either the lever 3 operated by the outer door handle 12 or the lever 4 operated by the inner door handle 13 acts on this common pawl 2 when the door handle 13 is rotated in the direction of the arrow f _t (FIG. 2). In its position 5 , shown in broken lines in FIG. 2, the lever 4 also locks the door from the outside, since it does not allow the lever 3 to move.

To block the actuation of the lock by the inner door handle 13 , a cam 6 is arranged according to the invention, which is braked by an elastic washer 7 and is rotatably connected to a pivot pin 8 that can be operated from inside the car so that it consists of the one shown in FIG End position 6 shown in solid lines & can be pivoted into a further end position 6 a shown in dashed lines. The fitting in its two end positions against a stop 9 cams operates as follows: In the "rest position" 6 a of the cam, the lock operates normally, and the cam is used where appropriate, only as a stop for the lever 4 when it reaches the end of its path of movement. In the "working position" 6b , the cam prevents the action of the lever 4 on the pawl 2, but allows the lever 4 to be turned into the position 5 . In this case it is not possible to open the door with the help of the inner door handle 13. However, there is nevertheless the possibility of moving the lever 4 into position 5 in the opposite direction to the arrow direction f _t by actuating the inner handle 13 and thereby locking the outer door handle or moving the lever to the position shown in FIG. 2 by means of the inner handle 13 To pivot the position shown in the lines, in which the outer door handle is operated and the door can thus be opened from the outside, since the positions of the cam 6 on the latch 2 and the lever 3 have no influence.

In order to prevent with certainty that the cam 6 can be unintentionally adjusted from inside the car by children, the pivot 8 actuating the cam 6 is arranged in such a way that it is inaccessible to children sitting in the car. According to one feature of the invention, this is achieved in that the pivot is not visible when the door is closed. For this purpose, the pivot 8, as shown in FIG. 1, is attached to the inside of the door close to the door rebate, where it can be covered by a sealing bead 14 of the cladding. It is also possible to arrange the pin 8 in the door rebate parallel to the axis 15 of the locking wheels 1 and 10. The pivot pin 8 can be actuated, for example, by a knurled head, a button or the like. In particular, however, it can be turned by means of a commonly used tool, such as a contact key, which the driver of the car always has to hand. In this case, it would be sufficient to provide a slot 16 on the front end of the pin 8 , into which the contact key can be inserted as a rotary key (cf. FIG. 3a).

An opening 17 can be provided in the cladding 14 in order to enable locking when the door is closed.

If the condition of inaccessibility for children is e.g. B. can not be met for reasons of space, the pivot pin 8 can be modified in the

explained arrangement can also be rotated via a lock drum actuated by the contact key.

Another embodiment of the invention is shown in FIGS. 4, 5 and 6 in the application to a different type of lock. In this case, the door is opened in such a way that the common lock bolt 21 is withdrawn from the tumbler 22 by either the outer door handle 23, for example, directly or the inner door handle 24 , which is non-rotatable with the lever 25, via the when the door is opened in the Arrow direction / ₂ displaceable rod 26 and the adjustment spring 27 is brought to the lock bolt 21 to act.

According to the invention, the lock safety device in this case has a safety lever 28 which can be pivoted about a pin 29 and which, in its locked position shown in solid lines in FIG. 5, rests with its inner end 31 against the actuating lever 25 and thus prevents the door from opening. The other end 32 of the lever 28 protrudes into a slot 30 of the door rebate and forms a handle through which the locking lever, made possible in the slot, can be shifted from the locking position into the inoperative position shown in broken lines in FIG. 5 and vice versa. Since the slot 30 is arranged in the door rebate, the safety lever can only be actuated when the door is open, so that the door cannot be opened from inside the car when the lock safety device is switched on.
In this embodiment too, the opening of the door by the inner door handle 24 can thus be prevented by appropriate adjustment of the securing element embodied as a lever 28 , without the operation or the fixing of the outer door handle 23 being impaired.

When the safety device is switched on, it is impossible for children or other people to operate the inner door handle, and it is also impossible to switch off the safety device, since it can only be switched after the door has been opened when the end of the lever 28 is exposed.
