Abstract

A magnetic joint includes a first component having a first interface; a second component having a second interface; a first magnet adjacent to the first interface; and a spherical magnet within a cavity formed in the second component, the cavity adjacent to the second interface, the spherical magnet movable within the cavity such that the spherical magnet is attracted to the first magnet to retain the first component to the second component such that the second component is articulatable with respect to the first first component.

Claims (26)

1. A magnetic joint, comprising:

a first component having a first interface;

a second component having a second interface;

a first magnet adjacent to the first interface; and

a spherical magnet within a non-spherical cavity formed in the second component, the non-spherical cavity adjacent to the second interface and is conformal with respect to the second interface, the second interface at least partially fits within the first interface and the spherical magnet movable within the non-spherical cavity such that the spherical magnet is attracted to the first magnet to retain the first component to the second component such that the second component is articulatable with respect to the first component.

2. The magnetic joint as recited in claim 1 , wherein the first component is a first bone and the second component is a second bone adjacent to the first bone.

3. The magnetic joint as recited in claim 1 , wherein the first component and the second component are adjacent components of an articulatable figure.

4. The magnetic joint as recited in claim 1 , wherein the first component and the second component are adjacent components of a skeleton.

5. The magnetic joint as recited in claim 1 , wherein the first magnet is partially exposed at the first interface.

6. The magnetic joint as recited in claim 1 , wherein the first magnet is completely hidden within the first component.

7. A magnetic joint for an articulatable figure, comprising:

a first component having a first interface;

a second component having a second interface, the second interface adjacent to the first interface the second component an articulatable portion of the articulatable figure;

a first magnet adjacent to the first interface; and

a spherical magnet within a non-spherical cavity formed in the second component, the non-spherical cavity adjacent to the second interface and conformal with respect to the second interface, the spherical magnet movable within the non-spherical cavity such that the spherical magnet is attracted to the first magnet to retain the first component to the second component such that the second component is articulatable with respect to the first component.

8. The magnetic joint as recited in claim 7 , wherein the first component is a torso and the second component is an arm.

9. The magnetic joint as recited in claim 7 , wherein the first component is a torso and the second component is a leg.

10. The magnetic joint as recited in claim 7 , wherein the first component is thigh and the second component is a lower leg.

11. The magnetic joint as recited in claim 7 , wherein the first component is an upper arm and the second component is a forearm.

12. The magnetic joint as recited in claim 7 , wherein the second interface at least partially fits within the first interface.

13. A magnetic joint for a skeleton, comprising:

a first bone having a first interface;

a second bone having a second interface, the second interface adjacent to the first interface, the second bone an articulatable portion of the skeleton;

a first magnet adjacent to the first interface; and

a spherical magnet within a non-spherical cavity formed in the second bone, the non-spherical cavity adjacent to the second interface and conformal with respect to the second interface, the spherical magnet movable within the non-spherical cavity such that the spherical magnet is attracted to the first magnet to retain the first bone to the second bone such that the second bone is articulatable with respect to the first bone.

14. The magnetic joint as recited in claim 13 , wherein the first bone and the second bone are synthetic.
