Description

BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS

(1) The invention will be explained in detail in the following using only one exemplary embodiment of the invention. In it

(2) FIG. 1 shows a perspective side view from obliquely below of the clip according to the invention,

(3) FIG. 2 shows a perspective view from below of the tip of the clip according to the invention, and

(4) FIG. 3 shows a sectional, perspective side view of the clip according to the invention.

DETAILED DESCRIPTION OF THE INVENTION

(5) The clip shown in the FIG. for fastening a first element on a second element comprises a head 1 and a tip 2. A shaft 3 composed of several partial sections extends between the head 1 and the tip 2.

(6) The shaft 3 has a first side 4 and a second side 5 arranged oppositely, relative to the first side 4, on a longitudinal axis A of the clip and running parallel to the first side 4. The first side 4 as well as the second side 5 extend from the head 1 in the direction of the tip 2. The first side 4 ends in an arched bent section 6 which is bent inward starting from the first side 4. The vertex of the arch of the bent section 6 forms a part of the tip 2. The second side 5 ends in an arched bent section 7 which is bent inward. The vertex of the arch of the bent section 7 forms a part of the clip tip 2.

(7) The first side 4 merges via an edge 8 into the flat base body 9 of a first side wall 10 extending from the first side 4 in the direction of the second side 5. The second side 5 merges via an edge 11 into the flat base body 12 of a second side wall 13 extending from the second side 5 in the direction of the first side 4.

(8) The clip shown in the FIGS. is constructed with mirror symmetry relative to a plane containing the longitudinal axis A and running parallel to the base body 9 and to the base body 12. Therefore, a third side wall 50 (not shown in FIG. 1) extends from the side 4 in the direction of the second side 5, wherein the third side wall 50 is constructed in accordance with the first side wall 10. Furthermore, a fourth side wall 51 not shown in the FIG. 1 extends from the second side 5 in the direction of the first side 4, wherein the fourth side wall 51 is constructed in accordance with the second side wall 13. The clip according to the invention in the embodiment shown in the FIGS. is a one-piece element and was produced by bending sections of a metallic section.

(9) The first side wall comprises a first protruding finger 14 which overlaps an area of the second side wall 13. To this end the second side wall 13 has the receptacle, which can be better seen in FIG. 3, in the shape of a depression 15. Furthermore, the first side wall 10 comprises a second protruding finger 16 (cf. FIG. 3). This second protruding finger 16 of the first side wall 10 overlaps another area of the second side wall 13. The first protruding finger 14 of the first side wall is aligned here with the flat base body 9 of the first side wall, whereas the second protruding finger 16 is bent inward and extends behind the second side wall 13. To this end the second finger 16 has a bent section 18 provided between the flat base body 9 and the end section 17 of the second finger 16 and which is at first bent inward and is then bent in the opposite direction so that the end section 17 of the finger 16 runs parallel to the base body 12 of the second side wall 13. The second side wall 13 comprises a protruding finger 19 which overlaps an area of the first side wall 10. The protruding finger 19 of the second side wall 13 is constructed comparable to the second protruding finger 16 in the first side wall and has an end section 20 which runs parallel to the base body 9 of the first side wall and has a bent section 21 which is provided between the base body 12 of the second side wall 13 and the end section 20.

(10) The base body 9 of the first side wall 10 has a narrow side 25. The base body 12 of the second side wall 13 has a narrow side 26. The narrow side 25 and the narrow side 26 are designed plane over a first section and run substantially parallel to one another in the section, wherein the plane section of the narrow side 26 of the second side wall 13 is longer than the plane section of the narrow side 25 of the first side wall 10. The second protruding finger 16 overlaps an area of the base body 12 of the second side wall 13 which borders the plane section of the narrow side 26 of the second side wall. In the area in which the second protruding finger 16 extends behind the base body 12 of the second side wall 13, the latter comprises a plane section of the narrow side 26. As can be especially well seen in the FIGS. 1 and 2, the plane section of the narrow side 25 and the plane section of the narrow side 26 are followed by a profile of projections 27, 28 and recesses 29, 30. Here, the particular projection 27, 28 of the particular side wall 10, 13 engages into an offset 30, 29 of the opposite side wall 13, 10. The projections 27, 28 are constructed in such a manner that they do not overlap with an area of the opposite side wall but rather only engage in offsets 29, 30 provided there.

(11) In the exemplary embodiment shown in the FIGS. the first side 4 and the second side 5 each have a flat base body. It can be recognized in FIG. 1 that the otherwise flat base body 4 has a small elevation 31. This clarifies that fact that the understanding of the concept “flat base body” used in the framework of this description, which provides a geometrically exactly flat base body only in an especially preferred embodiment, but in other embodiments—such as here—such base bodies can also be designated as “flat base bodies” which deviate from a geometrically exactly flat shape due to small projections.

(12) In the exemplary embodiment shown in the FIGS. the flat base body of the first side 4 stands at an angle of 90 degrees from the flat base body 9 of the first wall 10. The flat base body of the second side 5 stands at an angle of 90 degrees from the flat base body 12 of the second side wall 13. The first side wall 10 and the second side wall 13 are aligned with one another (their outwardly facing surfaces are in a plane). The embodiment shown in the FIGS. comprises four clip surfaces 40, 41, 42, 43. Each clip surface is part of a flexible element passing through a recess 44, 45, 46, 47 located in the particular transition between the side 4, 5 and the first side surface 10, the second side surface 13, the third side surface 50 and the fourth side surface 51. The particular elastic element comprises a bevel 48 which brings it about that the lacking element comes in contact with the hole edge when the clip is introduced into a hole of an element and is pressed inward by the further pushing into the clip counter to the resilient force, but after having passed through the hole in the element it springs outward again on account of the resilient force and as a result extends behind the corresponding element.

(13) The clip surfaces 40, 41, 42, 43 face the head 1. The head comprises four head surfaces 55, 56, 57, 58 which face the clip surfaces 40, 41, 42, 43. The first element and the second element are held between the clip surfaces 40, 41, 42, 43 and the head surfaces 50, 56, 57, 58 and as a result the second element is fastened on the first element.

(14) The head 1 has a side surface 100 and the contact surface (head surface) 55 facing the tip 2, wherein the side surface 100 of the head merges via a first rounded edge 101 into the contact surface 55 of the head and facing the tip 2, and the first side 3 merges via a second rounded edge 102 into the first side wall 10, and the first rounded edge 101 merges via an arched section 103 into the second rounded edge 102. The contact surface 55 of the head 1, which contact surface faces the tip 2, merges via an arched section 104 into the first side wall 10.
