Abstract

A magnet fastener includes a cup, a magnet received in the cup and a carrier. The carrier receives and holds the cup while the resilient support includes at least one projection that engages the cup and provides a biasing force to prevent rattling or ticking of the cup on the carrier.

First claim

What is claimed:

1. A magnet fastener, comprising:
a cup;
a magnet received in said cup; and
a carrier including a base and a resilient support including a planar disc that receives and holds said cup, said resilient support including at least one projection engaging said cup, wherein said resilient support has a substantially flat upper surface not including any sidewalls extending from the upper surface to prevent excess rigidity to said resilient support.

2. The magnet fastener of claim 1 , wherein said resilient support is substantially planar.

3. The magnet fastener of claim 2 , wherein said carrier includes an integral stem and lock.

4. The magnet fastener of claim 3 , wherein said cup includes an aperture received around said stem and captured between said resilient support and said lock.

5. The magnet fastener of claim 4 , wherein said upper surface faces said cup.

6. The magnet fastener of claim 5 , wherein said at least one projection projects from said upper surface toward said cup.

7. The magnet fastener of claim 6 , wherein engagement between said at least one projection and said cup deflects said planar disc causing said resilient material of said disc to provide a force biasing said cup on said stem into engagement with said lock whereby said cup is securely and positively held in place so as to prevent rattling of said cup on said carrier.

8. The magnet fastener of claim 7 , wherein said upper surface is continuous.

9. The magnet fastener of claim 8 , wherein said magnet is annular in shape and includes a central opening.

10. The magnet fastener of claim 7 , wherein said at least one projection comprises two opposed ribs on said upper surface of said disc.

11. The magnet fastener of claim 10 , wherein said magnet is annular in shape and includes a central opening.

12. The magnet fastener of claim 10 , wherein said upper surface is continuous.

13. The magnet fastener of claim 12 , wherein said at least one projection projects from said upper surface toward said cup whereby engagement of said cup by said at least one projection deflects said resilient support so as to produce a biasing force to securely and positively hold said cup in place on said carrier and prevent rattling.

14. A headliner assembly comprising a headliner and said magnet fastener of claim 2 .

15. A headliner assembly comprising a headliner and said magnet fastener set forth in claim 1 .
