Embodiment Construction

[0018] figure 1 A cross-sectional view of a fastener according to an embodiment of the invention is shown, wherein the protrusion protrudes from a plate 10 having a thickness T and comprises an inner side 4 and an outer side 3 . The inner side 4 and the outer side 3 of the extrusion mainly form walls capable of receiving frictional or positive locking elements such as screws. In particular, the inner side is provided for contacting a frictional or positive locking member and thereby achieving a positive and / or frictional locking. Typically, the interior of the protrusion formed by the inner side of the protrusion is shaped approximately like a cylinder.

[0019] in detail, figure 1 It is shown that the plate 10 extending across the main plane A has a base surface 2 projecting away from it. A predetermined base surface passes over the inner side of the extruded part via the throat 2a. The throat 2 a is designed such that the circular segment expands at least partially in a ...

Abstract

The invention relates to a fastener arranged for frictional or positive locking engagement with a frictional or positive locking member, the fastener comprising a protrusion realized as an extrusion, wherein the protrusion Protrudes from a plate that extends along the main plane and has a base surface facing away from the protrusion; and the protrusion includes an inner side, wherein the inner side forms a circle with an inner diameter Di in a plane parallel to the main plane; where parallel A first plane to the main plane includes a circle with a first inner diameter Di', and a second plane parallel to the main plane includes a circle with a second inner diameter Di", and the first plane is closer to the base surface than the second plane, And the first inner diameter Di' is larger than the second inner diameter Di".

Description

Background technique [0001] The invention relates to the subject-matter stated in the preambles of the independent claims. [0002] Such fasteners are well known and are generally provided and designed for engagement with a frictional or positive locking member, such as a screw, in particular a threaded threaded screw. Typically, the height of the protrusion is equal to or greater than the diameter of the frictional or positive locking member, such as the diameter of a screw. At the same time, the inner side of the protrusion generally has straight sides, ie the wall forming the protrusion realizes a substantially cylindrical, in particular straight hollow cylinder. Another feature of this type of fastener known from the prior art is the throat, which joins the inner side of the protrusion to the basic surface of the plate, wherein the radius of the circular segment is compared to the plate / The thickness of the material is about 1.25 times. [0003] Although these fastener...
