Abstract

A cover for a key is disclosed. The cover includes: a first wall; a second wall opposite to the first wall; and an outer wall extending between the first wall and the second wall, the outer wall defining a pair of slots extending therethrough, the slots being positioned opposite to each other on the outer wall, wherein the first wall, the second wall, and the outer wall define a closed chamber for receiving a bow of the key and an opening to the chamber.

Claims

1. A cover for a key, comprising:

a first wall, wherein the first wall defines a first cavity extending partially from an exterior surface of the first wall to an opposite interior surface of the first wall;

a metallic plate embedded in the first wall and positioned at least partially within the first cavity;

a first magnet inserted in the first cavity and fixedly attached to the metallic plate;

a second wall opposite to the first wall; and

an outer wall extending between the first wall and the second wall, the outer wall defining a pair of slots extending therethrough, the slots being positioned opposite to each other on the outer wall, wherein the slots are sized to interlock with lateral bow tips of an SC1 key and wherein the slots are rectangular slits,

wherein the first wall, the second wall, and the outer wall define a closed chamber for receiving a bow of the key and an opening to the chamber.

2. The cover of claim 1, wherein the slots are positioned on opposite sides of a plane which extends orthogonally through the first and second walls and which bisects the outer wall.

3. The cover of claim 1, wherein a width of at least one of the slots is greater than 0.75 millimeters.

4. The cover of claim 1, wherein a length of at least one of the slots is greater than 2 millimeters.

5. The cover of claim 1, wherein the first wall is in parallel spaced relation to the second wall and wherein a distance between the first wall and the second wall is between 0.75 millimeter and 12 millimeters.

6. The cover of claim 1, wherein a side edge of the first wall, a second side edge of the second wall, and end surfaces of the outer wall together form a rim which defines the opening.

7. The cover of claim 1, wherein a length of the opening is between 15 millimeters and 40 millimeters.

8. The cover of claim 1, wherein the first cavity is cylindrical.

9. The cover of claim 1, wherein the first magnet is a ring magnet.

10. The cover of claim 1, wherein the first magnet is a disk magnet.

11. The cover of claim 1, wherein the metallic plate comprises a metallic disk and wherein a first end face of the metallic disk forms a bottom wall of the first cavity.

12. The cover of claim 11, wherein a surface area of the first end face of the metallic disk is greater than a cross-sectional area of the first cavity.

13. The cover of claim 1, wherein the metallic plate comprises a metallic ring defining a central hole.

14. The cover of claim 1, wherein the second wall defines a second cavity extending partially from an exterior surface of the second wall to an opposite interior surface of the second wall.

15. The cover of claim 14, further comprising a second magnet inserted in the second cavity.

16. The cover of claim 1, wherein the first wall defines a first key ring aperture extending therethrough and the second wall defines a second key ring aperture extending therethrough, the first key ring aperture being in alignment with the second key ring aperture.

17. The cover of claim 1, wherein the metallic plate includes a plurality of protrusions extending from a planar surface of the metallic plate.

18. The cover of claim 1 wherein the magnet is attached to the metallic plate using an adhesive.

19. The cover of claim 1 wherein a first end face of the metallic plate forms a bottom wall of the first cavity.

20. The cover of claim 19 wherein a cross-sectional area of the metallic plate is greater than a cross-sectional area of the first cavity.
