Abstract

A magnet fastener includes a carrier connectable to a first component and a magnet for attachment to a second, metal component. The carrier includes structures for holding a magnet assembly including the magnet in a manner that reduces rattle caused by vibration but provides flex so the magnet can articulate and adjust to a surface of the metal component.

Claims (29)

1. A fastener, comprising:

a carrier having a receiver including a floor and a holder extending from said floor, said floor having an inner surface, an outer surface and a thickness defined therebetween, said floor further having an inner surface, an outer surface and a thickness defined therebetween, said floor further having a pair of closely spaced slots extending through said floor on one side of said holder, said pair of closely spaced slots defining therebetween a narrow region of said floor, said narrow region of said floor including an area thereof that is thicker than said thickness defined between said inner and outer surface of said floor that projects above adjacent regions of said floor, said narrow region of said floor being downwardly deflectable between said pair of closely spaced slots;

a magnet assembly disposed in said receiver and held therein between said floor and a portion of said holder;

said portion of said holder engaging a first surface of said magnet assembly; and

said narrow region of said floor being engaged against an opposite surface of said magnet assembly.

2. The fastener of claim 1 , said floor having a plurality of pairs of slots therein defining a plurality of narrow regions of said floor between adjacent ones of said slots.

3. The fastener of claim 2 , said slots being curved.

4. The fastener of claim 3 , each of said regions of said floor between adjacent slots having a protuberance thicker than other regions of said floor immediately adjacent thereto.

5. The fastener of claim 1 , said holder being a post extending from said floor, said post having a deflectable tab angling outwardly therefrom.

6. The fastener of claim 5 , said narrow region of said floor urging said magnet assembly against said tab.

7. The fastener of claim 6 , said post having a plurality of tabs angling outwardly therefrom.

8. The fastener of claim 1 , said narrow region of said floor urging said magnet assembly against said holder.

9. The fastener of claim 1 , said carrier having a mount extending away from said receiver for attaching said carrier to a component.

10. A carrier for a magnet fastener, for retaining a magnet assembly, said carrier comprising:

a floor having an inner surface and first and second pairs of closely spaced slots extending therethrough, each of said pairs of closely spaced slots defining in said floor therebetween a narrow region of said floor, each of said narrow regions of said floor including a protuberance projecting above said inner surface, and each being downwardly deflectable between said pair of closely spaced slots on opposite sides thereof, said narrow regions of said floor including said protuberance being thicker in a direction perpendicular to said floor;

a wall at least partly surrounding said floor at the perimeter thereof;

a post extending from said floor between said first and second pairs of slots on opposite sides of said post;

at least one deflectable portion of said post extending outwardly therefrom; and

said narrow region of said floor being configured for engagement against a side of a magnet assembly and further configured for biasing the magnet assembly toward said deflectable portion of said post.

11. The carrier of claim 10 , said post being hollow and defining openings therein, and said post including outward angled deflectable tabs aligned with said openings.

12. The carrier of claim 10 , said post being hollow and defining openings therein, and said post including outward angled deflectable tabs aligned with said openings.

13. The carrier of claim 10 , including mounts for attaching said carrier to a component, said mounts extending away from said wall.

14. A magnet fastener, comprising:

a fastener carrier including a receiver having a floor with an inner surface, a wall at least partly surrounding said floor, and a post extending away from said floor; and securing mounts extending away from said receiver adapted for attaching said fastener carrier to a component;

said post being hollow and defining openings therein, said post having outwardly angled tabs aligned with said openings, said tabs being deflectable toward said openings;

a magnet assembly including a cup disposed on said post and a magnet disposed in said cup, said cup having a bottom encircling said post between said floor and said tabs; and

first and second narrow regions of said floor on opposite sides of said post, each of said narrow regions defined within said floor between different pairs of closely spaced slots extending through said floor, said narrow regions of said floor having a thicker portion in a direction perpendicular to said floor, and said narrow regions of said floor engaging said magnet assembly and urging said magnet assembly against said tabs.

15. The magnet fastener of claim 14 , said cup being metal and said fastener carrier being plastic.

16. The magnet fastener of claim 14 , said narrow regions of said floor between said slots of said pairs of slots having protuberances thereon, said protuberances supporting said bottom of said cup.
