Abstract

A fastening element is provided. The fastening element includes a gripping portion having a first face and a second face the first face of the gripping portion comprising a plurality of gripping elements, and an anchoring portion offset from the second face and extending parallel thereto so as to form a flange portion, wherein the flange portion comprises at least one chamfer located at a terminal section of the flange portion.

First claim

What is claimed is:

1. A fastening element, comprising:
a gripping portion having a first face and a second face, the first face of the gripping portion comprising a plurality of gripping elements; and
an anchoring portion offset from the second face and extending parallel thereto so as to form a flange portion, wherein the flange portion comprises at least two chamfers located at a terminal section of the flange portion, one of the at least two chamfers extending in a plane forming an acute angle to the second face.

2. The fastening element of claim 1 , wherein at least one chamfer of the at least two chamfers extends along a first plane perpendicular to the second face.

3. The fastening element of claim 2 , wherein at least one chamfer of the at least two chamfers forms an angle with a second plane perpendicular to the second face ranging between 1 and 60 degrees.

4. The fastening element of claim 1 , wherein the acute angle ranges between 10 and 30 degrees.

5. The fastening element according to claim 1 , comprising a supporting portion between the gripping portion and the anchoring portion, wherein the supporting-portion width is between 5 and 95 percent of the gripping portion width.

6. The fastening element according to claim 1 , wherein at least two other sides of the gripping portion and the anchoring portion are void of any flange.

7. The fastening element according to claim 1 , wherein a thickness of the fastening element, defined as the distance from a plane comprising a top of the first face to a plane comprising a bottom surface of the anchoring portion, is between 4 and 10 millimeters.

8. A fastening element, comprising:
a gripping portion having a first face and a second face, the first face of the gripping portion comprising a plurality of gripping elements;
a supporting portion being defined by at least two supporting-portion walls extending from the gripping portion in a direction opposite that of the gripping elements, the supporting portion having a supporting-portion width smaller than a gripping-portion width of the gripping portion, such that a top flange is formed by the gripping portion relative to the supporting portion on at least one side of the fastening element; and
an anchoring portion extending from a distal end of at least one supporting-portion wall and parallel to the gripping portion thereby defining a bottom flange relative to the supporting portion on the at least one side corresponding to the top flange,
wherein the bottom flange comprises at least two chamfers located at a terminal section of the bottom flange, wherein one of the at least two chamfers forms an angle with a plane perpendicular to the second face ranging between 1 and 60 degrees.

9. The fastening element according to claim 8 , wherein one of the at least two chamfers is a top chamfer, the top chamfer forming an acute angle when measured relative to the second face.
