DETAILED DESCRIPTION

(11) The following description is merely exemplary in nature and is in no way intended to limit the present disclosure or its application or uses. It should be understood that throughout the description, corresponding reference numerals indicate like or corresponding parts and features.

(12) In FIG. 1, an isometric view of an exemplary wedge drive tool 1, in general a slider arrangement 1, is shown. This slider arrangement 1 has a slider upper portion 10 and a slider lower portion 20 which, due to a relative movement with respect to the slider upper portion 10 can be displaced along guides 30 from an initial position into a working position and vice versa. The bracket 31 holds the components in the guide 30. However, this could also be implemented differently and is not relevant for the present invention.

(13) In FIG. 2, an isometric view of a portion of the wedge drive tool 1 from FIG. 1 is shown, wherein the return device 40 is shown in a non-mounted position for a better understanding of example embodiments of the invention. In this figure, an attachment means 60 is represented, as is used in the solution according to the example embodiments according to FIGS. 7 and 8. For such an embodiment, only a single mounting position M1 for the attachment means 60 is provided. Depending on the final rotational position in which the screw plug 50 is mounted in its mounting position, the attachment means 60 shown can be mounted only in a certain orientation, in which the projection 65 of the attachment means is positioned either below or above the projection 51 of the screw plug 50. These two mounting positions of the attachment means 60 are shown in FIGS. 7 and 8. And likewise, the corresponding rotational position of the screw plug 50. The protruding projection 65 of the attachment means 60 extends in each case into the region within the envelope contour of the screw head 52, which is represented with dotted lines. During the rotation on the screw plug 50, said screw plug is blocked by the projection 65.

(14) In FIG. 3, an isometric view of the portion of the wedge drive tool 1 according to a conventional solution with a partial cross-sectional view in the region of the return device 40 can be found. The screw plug is secured by a washer against unscrewing. This securing is a not positive locking; the force acts (cyclically) axially on the locking screw.

(15) The return device 40 is designed to bring about the initial position of the slider upper portion 10 and slider lower portion 20 in the tool. Moreover, it can be seen that the return device 40 comprises said screw plug 50 at the end in order to attach the return device 40 in a recess 11 of the slider arrangement 1, which can be seen more clearly in the view of FIG. 4. In order to limit the rotation angle of the screw plug 50, said screw plug cooperates with the attachment means 60 which is also shown.

(16) In FIGS. 5 to 8, example embodiments of the implementation of the rotation prevention means are shown. In each case, the front view onto the region with the screw plug 50 can be seen. For this purpose, in the examples shown, the screw plug 50 in each case comprises 5 rotation prevention means 51 in the form of projections extending radially outward, thus transversely with respect to the direction of actuation of the return device 40. Another number of the projections 51 is also conceivable.

(17) For the mounting of the attachment means 60, in the embodiment according to FIGS. 5 and 6, two alternative mounting positions M1, M2 are provided, wherein, depending on the angular position of the screw plug 50, only a mounting in one of the two mounting positions M1, M2 is possible, while the respective other mounting position is blocked or partially covered by a projection 51 or a protrusion of the rotation prevention means 51. These two mounting possibilities are shown for the example embodiment in FIGS. 5 and 6.

(18) The rotation prevention means 51 shown are provided on the screw head 52. In all the embodiment variants, the rotation of the screw plug 50 beyond a maximum acceptable rotation angle is prevented (indicated by the two dotted lines in FIG. 5 and the angle in between). To the extent that the rotation prevention means 51 are arranged at an equidistant spacing when viewed in circumferential direction, the maximum acceptable rotation angle with respect to the positions of the rotation prevention means 51 is always the same size, wherein, depending on the angular position of the screw plug 50, the actually possible rotation angle can also turn out to be smaller.
