DETAILED DESCRIPTION OF THE INVENTION

[0039] FIG. 1 shows an enlarged detail of a perspective view of a motor vehicle door handle arrangement with the carrier 1 of the motor vehicle door handle arrangement. In the illustration according to FIG. 1, the securing element 2 and the actuation screw 3 are already inserted into the carrier 1. The cylindrical receptacle 5 can be discerned at the left image edge, which serves for receiving a closing cylinder not illustrated in FIG. 1.

[0040] As soon as the closing cylinder has been inserted into the cylindrical receptacle 5 from above, the securing element 2 is displaced to the right in the image plane according to FIG. 1 by means of the actuation screw 3 for assembling and securing the closing cylinder. This is effected in that the screw is screwed into the thread in the securing element 2. Displacing the securing element 2 to the right in the image plane according to FIG. 1 achieves a form fit between corresponding protrusions on the securing element 2 and the inserted closing cylinder. Thereby the closing cylinder is fixed and secured in its mounting position by means of the securing element 2. The securing element 2 is a slider in the form of a U-shaped bracket, which can be displaced to the right or to the left in the image plane according to FIG. 1 by actuation of the actuation screw 3. As can as well be taken from the illustration according to FIG. 1, the securing element 2 has a stop nose 4, which rests against the head of the actuation screw 3 in the final mounting position.

[0041] FIGS. 2 to 4 show the section A-A according to FIG. 1 with the securing element 2 and the actuation screw 3 in different positions.

[0042] FIG. 2 shows the section A-A according to FIG. 1 with the position of the actuation screw 3 when inserting securing element 2 and actuation screw 3 into the carrier 1. As can be discerned from FIG. 2, the carrier 1 comprises a recess 6, which is dimensioned such that the head of the actuation screw 3 can be inserted in the carrier 1 by means of said recess 6 in the carrier 1.

[0043] After insertion into the carrier 1 of the securing element 2 and the actuation screw 3 screwed into a thread of the securing element 2, the actuating screw 3 is screwed out until said screw is brought in its transport position according to the illustration in FIG. 3. In the transport position, the actuating screw 3 is secured on the carrier 1 configured as a cage both in axial direction and radial direction by means of respective stops on the carrier 1. Here, the term axial direction or radial direction refers to the axis of the actuation screw 3 respectively the radial direction perpendicular to said axis of the actuation screw 3. To that end, the carrier 1 comprises a radial stop 7, against which the actuation screw rests in radial direction in the transport position according to FIG. 3. The carrier 1 furthermore comprises a radial stop preventing that the actuation screw 3 may again pivot out upwards or downwards from the transport position in the image plane according to FIG. 3. By the configuration of the carrier 1, the actuating screw 3 is thus secured in its position in the transport position according to FIG. 3. Due to the fact that the actuating screw 3 still engages in the thread in the securing element 2, the securing element 2 is secured in the transport position according to FIG. 3 at the same time.

[0044] After insertion of the closing cylinder into the cylindrical receptacle 5 provided to that end in the carrier 1 of the motor vehicle door hand arrangement, the actuation screw 3 is brought into the mounting position according to FIG. 4. To that end, the actuation screw 3 is screwed into the thread in the securing element 2 until the actuation screw 3 buts against the stop 8 on the carrier 1. Once the actuation screw 3 is brought into the position according to FIG. 4 and buts against the stop 8 on the carrier 1, further actuation of the actuation screw 3 automatically leads to a displacement of the securing element 2 in the rightward direction in the image plane according to FIG. 4. By means of said displacement of the securing element 2 to the right in the image plane, the U-shaped bracket, which serves as a securing element 2, comes into form-fit engagement with the closing cylinder, thereby securing the closing cylinder in the mounting position thereof.

[0045] As can be taken from the plan view according to FIG. 5 in the mounting position, the securing element 2 has a stop nose 4, which in the mounting position rests against the head of the actuation screw 3. Just as well, FIG. 5 shows that the head of the actuation screw 3 rests against the stop 8 on the carrier 1. Furthermore, the stop nose 4 on the securing element 2 is dimensioned such that a contact between the head of the actuation screw 3 and the stop nose 4 occurs, but the securing element 2 does not rest against the carrier 1 in a pressing manner apart from that. This prevents a planar pressing between the securing element 2 and the carrier 1. As a result, damages to the carrier 1 during the assembly of the securing element 2 are prevented. This further enables that it is possible to eventually replace the closing cylinder without possible damages occurring during re-installation since contact and thus planar pressing between the securing element 2 and the carrier 1 is reliably prevented by the dimensioning of the stop nose 4 on the securing element 2.

[0046] By means of the, in the axial direction, rear stop 7 on the carrier 1 it is in turn enabled to screw the actuation screw 3 out of the thread in the securing element 2 such that upon reaching the stop 7 in the axial direction when screwing-out the actuation screw 3, a further actuation of the actuation screw 3 in the screw-out direction effects a displacement of the securing element 2 to the left in the image plane. As a result, the securing element 2 can in turn be displaced all the way to the left until the securing element 2 abandons the engagement on the closing cylinder and then the closing cylinder can be replaced.
