In order to prevent loosening of Aufschraubstücks 5, the bottom surface, that is, the second support track 54 of the second receiving groove 51 obliquely to the Aufschraubstück-back 53 is inclined. The Aufschraubstück back 53 is in the FIGS. 2 to 4 formed parallel or substantially parallel to the door opening direction TÖ and / or door closing direction TS. This second inclination is formed such that the second support track 54 of the second receiving groove 51, seen from the parallel to the door opening TÖ Aufschraubstück back 53 from, drops in the door closing direction TS, ie in door opening direction TÖ increases, ie exactly opposite to the first inclination of the embodiment in the sectional view AA (see Figures 2c . 3d in connection with 3e, 5a and 5b). The second inclination is formed at an angle α between the Aufschraubstück back 53 and the second support web 54.

By falling in the door closing direction TS second inclination of the second support track 54, the second adjusting screw 6 wedged with the Aufschraubstück 5 when the force F2 acts on the Aufschraubstück 5. The wedging occurs by the interaction of the screwed second adjusting screw 6 and rising in the door opening direction TÖ second support track 54. By the force F2, the Aufschraubstück 5 will move in the door closing direction TS, but by the fixed second adjusting screw 6 and the second support track 54, a displacement of the Aufschraubstücks 5 by the door opening direction TÖ rising direction of the second support track 54 only slightly or not at all is possible. The Aufschraubstück 5 is pressed by the force F2 even more firmly under the second adjusting screw 6.

The second adjusting screw 6 is arranged according to the second support track 54 at the angle α in Aufschraubstück 5. In the illustrated embodiment, the second threaded hole 44 is formed in the pivot case 4 for the second adjusting screw 6 at the angle α to the contact surfaces K, ie to the pivot latch front side 43 and the Aufschraubstück back 53. The contact surfaces are, as already mentioned above, in the illustrated embodiment of Figures 2 . 3 and 4 formed parallel or approximately parallel to the door opening direction.

In the FIGS. 3b to 3e simplified sectional views of the Aufschraubstücks 5 and the pivot latch 4 are shown in which the edges of the radii of curvature of the slot 52 and the receiving groove 51 are not shown. In the figures, the surfaces between which the inclination is formed, shown in bold, which in this embodiment, the support track 54 and the Aufschraubstück-back 53 are. Next, the angle α of the support track 54 to the front side 43 of the pivot latch 4 and the back 53 of the Aufschraubstücks 5 is shown. The angle α can for the absorption of the force F1 on the left side of the Aufschraubstücks 5 and the pivot latch 4 (section AA, shown in FIGS FIGS. 3b and 3c ), and for the force F2 on the right side of the Aufschraubstücks 5 and the pivot latch 4 (section BB, shown in the Figures 3d and 3e ) be formed in opposite directions. In this case, the Aufschraubstück 5 left a first support track 54, as in FIGS. 3b and 3c , for self-locking force F1 on and a second support track 54 right, as in the Figures 3d and 3e , for self-locking at force F2. The angles α of the inclinations of the left and right support webs 54 may be different in size.

In the FIGS. 4 and 5 are different positions of Aufschraubstücks 5 shown on the pivot latch 4, wherein in the FIGS. 4a and 4b the section AA through the door opener from the FIG. 1 . 2a or 3a is shown and in the FIGS. 5a and 5b the cut BB from the FIG. 1 . 2a or 3a is shown.

The FIGS. 4a and 4b show the section AA through the door opener 1 and thus also show the design of the door opener in section AA for self-locking the movement of the Aufschraubstücks 5 at a force F1. In FIG. 4a the Aufschraubstück 5 is fixed in the door closing direction TS maximum shifted position on the pivot latch 4. In the FIG. 4b the Aufschraubstück 5 is fixed in the door opening direction TÖ maximally ejected position on the pivot latch. Also in each position in between the Aufschraubstück 5 can be fixed by the continuous adjustment on the pivot case 4.

The FIGS. 5a and 5b show the section BB through the door opener 1 and thus show the design of the door opener in section BB for self-locking the movement of the Aufschraubstücks 5 at a force F2. In FIG. 5a the Aufschraubstück 5 is fixed in the door closing direction TS maximally inserted position on the pivot latch 4. In the FIG. 5b the Aufschraubstück 5 is fixed in the door opening direction TÖ maximally ejected position on the pivot latch. Also in each position in between the Aufschraubstück 5 can be fixed by the continuous adjustment on the pivot case 4.

In order to obtain the desired position of Aufschraubstücks 5, both adjusting screws 6 must be solved. The Aufschraubstück 5 can then be moved according to the position of the lock latch, not shown. Subsequently, by fixing the two adjusting screws 6, the Aufschraubstück 5 held securely on the pivot latch 4.

As in the FIGS. 2a and 3a 4, two guide strips 91 are parallel to the door opening direction formed on the front side 43 of the pivoting latch 4, which engage in two guide grooves 92 in the Aufschraubstück back 53 and thus form a guide 9 of the Aufschraubstücks 5 on the pivoting latch 4. Due to the design of the guide rails 91 and the guide grooves 92 parallel to the door opening direction, the Aufschraubstück 5 exactly guided parallel, or substantially parallel, be moved to the door opening direction. A rotation of the Aufschraubstücks 5 on the latch 4 about an axis perpendicular to the contact surfaces is prevented by the guide 9. If in the embodiment of FIGS. 1 . 2 and 3 the force F1 acts on the Aufschraubstück, the first adjusting screw 6 causes a self-locking but the second adjusting screw 6 has the urge to solve. When the force F2 acts on the Aufschraubstück, causes the second adjusting screw 6 is a self-locking but the first adjusting screw 6 has the urge to disengage, since the inclinations are formed in opposite directions. Through the guide 9 a tilted position of the Aufschraubstücks 5 is prevented on the lock latch 4 and prevents loosening of the corresponding adjusting screws 6.

In the FIGS. 6 In addition to the first embodiment of the inclinations between the support track 54 and the Aufschraubstück-back 53 further embodiments are shown. It is essential that in all embodiments in the FIGS. 6 an inclination between the Aufschraubstück back 53 and the support web 54 is formed. The surfaces between which the inclination is formed are in the FIGS. 6 shown in bold. The embodiments differ from each other in how the Aufschraubstück back 53 and the support track 54 to the door opening direction TÖ, or to the door closing direction TS are formed. In the FIGS. 6 the adjusting screw 6 is not shown. The underside of the adjusting screw 6, not shown, acts in all embodiments of the FIG. 6 with the support track 54 and causes at force F1 or F2 a self-locking in the door opening direction TÖ or door closing direction TS.

The Figures 6a and 6b show an education of the inclination at an angle a, as already associated with the FIGS. 1 to 5 has been described. It is possible that both support tracks 54 of the door opener 1 of the Aufschraubstücks 4 as in FIG. 6a or 6b are formed. As a result, a self-locking is always possible only in the door opening direction TÖ or door closing direction TS. It is also possible that a support track 54 of the Aufschraubstücks 4, as in FIG. 6a and the second as in FIG. 6b shown, are formed. This allows self-locking in the door opening direction TÖ and in the door closing direction TS.

In contrast to the previously described embodiments are in the FIGS. 6c and 6d the support tracks 54 formed parallel or substantially parallel to the door opening direction TÖ and door closing direction TS and the Aufschraubstück back 53 formed at an angle α to the door opening direction TÖ or door closing direction TS. In this case, the swivel trap front side 43 is formed according to the angle α to the door opening direction TÖ or door closing direction TS. The inclination in this embodiment is by the door opening direction TÖ or door closing direction TS parallel or substantially parallel support tracks 54 and the lower formed on the angle α to the door opening direction TÖ or door closing direction TS Aufschraubstück back 53. In the FIG. 6c a self-locking is achieved by the action of the force F1 on the Aufschraubstück 5.

In the FIG. 6d a self-locking is achieved by the action of the force F2 on the Aufschraubstück 5. In the embodiments of the FIGS. 6c and 6d It should be noted that a self-locking either in the door opening direction TÖ or in the door closing direction TS can be achieved by the different obliquely formed Aufschraubstück back 53. In the various embodiments, therefore, the Aufschraubstück-back 53 may be formed inclined in their entirety only in one direction in order to ensure a continuous displacement of the Aufschraubstücks 5 on the pivoting latch 4.

Another embodiment of the inclinations is in the FIGS. 6e to 6f shown. As in the preceding embodiment of the FIGS. 6c and 6d the Aufschraubstück back 53 is formed at an angle β to the door opening direction TÖ or door closing direction TS and not parallel thereto. In the FIGS. 6e and 6f In addition to the inclination of the Aufschraubstück-back 53, the support track 54 is formed inclined. The inclination between Aufschraubstück back 53 and support track 54 includes the angle α. That is, the support track 54 is inclined at an angle α + β to the door opening direction TÖ or door closing direction TS. It is in FIG. 6e the Aufschraubstück back 53 formed at the angle β falling to the door opening direction TÖ and the support path 54 formed at the angle α also falling to the door opening direction TÖ. In FIG. 6f is the Aufschraubstück back 53 at the angle β falling to Door closing direction TS formed and the support path 54 formed at the angle α also falling to the door closing direction TS. In the FIG. 6e a self-locking is achieved by the action of the force F1 on the Aufschraubstück 5. In the FIG. 6f a self-locking is achieved by the action of the force F2 on the Aufschraubstück 5.

In the embodiments of the Figures 6g and 6h is the inclination between Aufschraubstück back 53 and support track 54 to each other in opposite directions to the door opening direction TÖ or door closing direction TS formed at an angle γ. It is in FIG. 6g the Aufschraubstück back 53 formed at the angle β rising to the door opening direction TÖ and the support web 54 formed at the angle α falling to the door opening direction TÖ. The angle α is greater than the angle β. As a result, self-locking is achieved when the force F1 acts on the screw-on piece 5. In the FIG. 6h the Aufschraubstück back 53 is formed at the angle β rising to the door closing direction TS and the support track 54 formed at the angle α falling to the door closing direction TS. The angle α is greater than the angle β. As a result, self-locking is achieved when the force F1 acts on the screw-on piece 5.

As in the embodiments of the FIGS. 6c and 6d also applies to the embodiments of FIGS. 6e to 6g in that a self-locking in the door opening direction TÖ or in the door closing direction TS can be achieved by the different obliquely formed Aufschraubstück back 53. In the various embodiments, therefore, the Aufschraubstück-back 53 may be formed inclined in their entirety only in one direction in order to ensure a continuous displacement of the Aufschraubstücks 5 on the pivoting latch 4.

The FIGS. 7a and 7b schematically show a portion of Aufschraubstücks 5. Aufschraubstück the front side 55 is in the FIGS. 7 indicated by an oval circle and not fully illustrated. FIG. 8 shows a Aufschraubstück 5 with two support webs 54, which as in the Figure 7a are formed, in which case the formation of the support webs 54 can be seen in the Aufschraubstück 5. In the Figure 7a the support track 54 is designed for a cylinder head screw. In the receiving groove 51, which can receive the screw head 61 of the cylinder head bolt and the screw head in the door opening direction TÖ or door closing direction TS, a slot 52 is formed, which is penetrated by the screw shaft 62. The support track 54 in the Figure 7a is designed as a plane.

FIG. 7b shows a support track 54 for a countersunk screw. Like in the Figure 7a is in the FIG. 7b a receiving groove 51 and a slot 52 is formed. In contrast to Figure 7a is in the FIG. 7b formed the support track 54 as a support surface for a countersunk screw. The support track 54 is formed V-shaped, wherein at the top of the V, the slot 52 is formed.
