"Power-operated device for closing doors, lids or the like, in particular of motor vehicles "

The invention relates to a power operated device for closing doors, lids, or the like, especially of motor vehicles that are in a the closed position of the door or the like closely adjacent position can be activated via a switch and the form-fitting cooperating with one another, on the door or the like and on an adjoining one Has actuating elements arranged fixed to the vehicle, one of which is stationary and one of which is via the auxiliary power drive is designed to be movable.

Such a locking device is already known from DE-AS 10 57 496. The known device requires a rack, a pinion and an overrunning clutch that is inserted into the pinion drive.

is switched. It thus has a relatively complicated structure.

The present invention was therefore based on the object of developing such a locking device so that it has a simple, uncomplicated structure and is therefore inexpensive to manufacture.

In the case of a locking device of the type defined above, this object is achieved according to the invention in that that the movable actuator as "" to a Axis pivotable closing finger and the interacting with it fixed actuating element is designed as a driving buffer, and that the interacting Areas of both actuators are designed so that they can only be taken over a limited swivel angle range of the closing finger.

Advantageous embodiments of the invention can be found in the further patent claims.

The subject matter of the invention is intended below with reference to an exemplary embodiment shown in the drawing are explained in more detail.

FIG. 2 shows, on a larger scale, a section along the line II-II in FIG. 1.

The door 1 of a motor vehicle 2 shown in the drawing is in two different positions in FIG. 2 shown. And that once in broken lines in a position and closely adjacent to the closed position on the other hand in solid lines in their closed position. To transfer the door 1 from the former Position in the second-named position is used by a servo-locked position Locking device, which will be described in more detail below.

At the door 1 is connected to the vehicle electrical system electric switch 3 attached, the plunger 3a when the door 1 is pressed into the with interrupted The position shown in the lines is supported on a component 4 fixed to the vehicle. This actuates switch 3 and an electric motor 5 fixed to the vehicle is activated via a line connection (not shown), which is used to drive a closing finger 7 pivotable about an axis 6. This closing finger 7, the 360 ° is pivotable, acts - as can be seen from Fig. 2 of the drawing - only in a limited pivot angle range with a fixed drive buffer 8 arranged on the door 1 in a form-fitting manner for moving the door 1> in their closed position drawn with continuous lines. The pivoting of the closing finger 7 takes place in the direction of arrow 9.

In Fig. 2 of the drawing, the closing finger 7 is with solid lines in its starting position, with broken lines at the beginning of its working area with the take-away buffer 8 and with dash-dotted lines at the end of this cooperation area shown.

The control of the electric motor 5 can be done in such a way that it is activated via the switch 3 only when closing, i.e. pressing it, door 1 is activated and the closing finger 7 then pivoted through 360 °. But it would also be conceivable to open the electric motor 5 each time and To activate the closing of the door 1 and thus to cause pivoting movements of the closing finger 7 of 180 ° in each case.

The solution according to the invention thus becomes a simple one Possibility created to achieve a comfortable and quiet closing of vehicle doors, with manual only It is necessary to press the door lightly until it is close to its closed position.
