Abstract

A fastening element includes a gripping portion having a gripping face and a back face opposite the gripping face, an anchoring portion comprising an anchor proximal end affixed to the gripping portion and an anchor distal end, the anchoring portion comprising at least one resilient clip configured to anchor the fastening element in a substrate with a retention force greater than an insertion force necessary for inserting the anchoring portion into a mounted position on a substrate.

First claim

What is claimed is:

1. A fastening element, comprising:
a gripping portion having a gripping face and a back face opposite the gripping face, wherein the gripping face comprises at least one of a plurality of hooks and/or a plurality of loops; and
an anchoring portion comprising an anchor proximal end affixed to the gripping portion and an anchor distal end, the anchoring portion comprising at least one resilient clip configured to anchor the fastening element in a substrate with a retention force greater than an insertion force necessary for inserting the anchoring portion into a mounted position on a substrate, wherein
the at least one resilient clip comprises:
a clip proximal end located in proximity to the anchor distal end and a clip distal end located in proximity to the anchor proximal end;
a compression portion extending from the clip proximal end and configured to cause a deflection of the at least one clip toward a longitudinal axis of the anchoring portion during insertion of the anchoring portion into a receiver of the substrate;
a shoulder extending from a terminus of the compression portion toward the longitudinal axis of the anchoring portion and parallel to a radial axis of the anchoring portion, wherein the radial axis is orthogonal to the longitudinal axis; and
a retaining portion configured to exert a retaining force on the substrate based on the resilient action of the at least one clip, the retaining portion extending at a non-orthogonal angle toward the clip distal end as measured relative to the radial axis of the anchoring portion.

2. The fastening element according to claim 1 , wherein in an at-rest position of the resilient clip, the shoulder extends substantially perpendicularly to the longitudinal axis of the anchoring portion.

3. The fastening element according to claim 1 , comprising a shoulder buffer portion extending substantially perpendicularly from the shoulder toward the clip distal end.

4. The fastening element according to claim 1 , wherein the non-orthogonal angle ranges between 10 and 80 degrees as measured relative to a radial axis of the anchoring portion.

5. The fastening element according to claim 1 , wherein the insertion force ranges between about 25 and 45 N and the retention force is higher than 133 N.

6. The fastening element according to claim 1 , wherein the gripping face comprises a plurality of hooks integrally molded with the fastening element.

7. The fastening element according to claim 1 , wherein a length of the at least one resilient clip ranges between 3.5 and 5.5 mm as measured from a tip of the clip distal end to a base of the clip proximal end.

8. The fastening element according to claim 1 , wherein the anchoring portion is integrally molded with the gripping portion.

9. The fastening element according to claim 1 , wherein the anchoring portion is fastened to the back face.

10. The fastening element according to claim 9 , wherein the fastening is performed by at least one of gluing and overmolding.

11. The fastening element according to claim 1 , wherein a clearance between the clip distal end and the back face ranges between 0.5 and 2 mm.

12. The fastening element according to claim 1 , wherein a width of the at least one clip ranges between 0.9 and 2.6 mm.

13. The fastening element according to claim 1 , wherein the fastening element and anchoring portion are molded of a thermoplastic material.

14. The fastening element according to claim 1 , wherein the shoulder has a width ranging from 0.4 to 1.5 mm.

15. A fastening element, comprising:
a gripping portion having a gripping face and a back face opposite the gripping face, wherein the dripping face comprises at least one of a plurality of hooks and/or a plurality of loops;
an anchoring portion comprising an anchor proximal end affixed to the gripping portion and an anchor distal end, the anchoring portion comprising at least one resilient clip configured to anchor the fastening element in a substrate with a retention force greater than an insertion force necessary for inserting the anchoring portion into a mounted position on a substrate, wherein
the at least one resilient clip comprises:
a clip proximal end located in proximity to the anchor end and a clip distal end;
a compression portion extending at an angle from the clip distal end and configured to cause a deflection of the at least one clip toward a longitudinal axis of the anchoring portion during insertion of the anchoring portion into a receiver of the substrate;
a shoulder extending from a terminus of the compression portion toward the longitudinal axis of the anchoring portion and parallel to a radial axis of the anchoring portion, wherein the radial axis is orthogonal to the longitudinal axis; and
a retaining portion configured to exert a retaining force on the substrate based on the resilient action of the at least one clip, the retaining portion extending at a non-orthogonal angle toward the clip proximal end as measured relative to the radial axis of the anchoring portion.
