Abstract

A device may comprise a housing having a straight rounded edge. A self-aligning connector at the straight rounded edge may comprise a cylindrical magnet oriented with its axis substantially parallel to the straight rounded edge. The cylindrical magnet is for magnetically engaging a magnet of another connector so as to align and connect the self-aligning connector with the other connector. The self-aligning connector may comprise mounting structure configured to mount the cylindrical magnet at the straight rounded edge of the housing with the axis of the cylindrical magnet being substantially parallel to the straight rounded edge of the housing. The device may include two such self-aligning connectors, spaced apart from one another, along a single straight rounded edge of the device housing.

Claims

1. A magnetically connectable device comprising:

a generally cuboid-shaped housing having a surface that is either of a sidewall of the housing and a corner adjoining two adjacent faces of the housing, the surface being straight due to the generally cuboid shape of the housing but having a curved transverse cross section and defining a straight rounded edge;

a self-aligning connector at the straight rounded edge of the housing, the self-aligning connector comprising a magnetic cylinder oriented with its axis substantially parallel to the straight rounded edge, the magnetic cylinder for magnetically engaging a magnet of an other connector so as to align and connect the self-aligning connector with the other connector with hinge-like pivoting motion between the self-aligning connector and the other connector at the straight rounded edge of the housing.

2. The device of claim 1 wherein a curved face of the magnetic cylinder is substantially coextensive with a curved profile of the straight rounded edge of the housing.

3. The device of claim 1 wherein the straight rounded edge of the housing wraps around a curved face of the magnetic cylinder.

4. The device of claim 1 wherein the magnetic cylinder has a radius of curvature that is substantially equal to a radius of curvature of the straight rounded edge.

5. The device of claim 1 wherein a diameter of the magnetic cylinder is slightly smaller than a thickness of the device.

6. The device of claim 1 wherein the magnetic cylinder has an axial magnetic orientation and is fixed with respect to the housing.

7. The device of claim 1 wherein the magnetic cylinder has a diametric magnetic orientation and is rotatable along its axis with respect to the housing.

8. The device of claim 1 wherein the self-aligning connector is a first self-aligning connector, wherein the magnetic cylinder is a first magnetic cylinder, and wherein the device further comprises a second self-aligning connector at the straight rounded edge of the device, the second self-aligning connector comprising a second magnetic cylinder coaxial with the first magnetic cylinder of the first self-aligning connector, the second magnetic cylinder for magnetically engaging a magnet of a further connector so as to align and connect the second self-aligning connector with the further connector, the first and second self-aligning connectors being spaced apart from one another along the straight rounded edge.

9. The device of claim 1 wherein the housing is watertight and wherein the magnetic cylinder is encased by the watertight housing.

10. A self-aligning connector of a generally cuboid-shaped magnetically connectable device housing having a surface that is either of a sidewall of the housing and a corner adjoining two adjacent faces of the housing, the surface being straight due to the generally cuboid shape of the housing but having a curved transverse cross section and defining a straight rounded edge, the self-aligning connector comprising:

a magnetic cylinder for magnetically engaging a magnet of an other connector so as to align and connect the self-aligning connector with the other connector with hinge-like pivoting motion between the self-aligning connector and the other connector at the straight rounded edge of the housing; and

mounting structure configured to mount the magnetic cylinder at the straight rounded edge of the device housing with an axis of the magnetic cylinder being substantially parallel to the straight rounded edge of the device housing.

11. The self-aligning connector of claim 10 wherein the mounting structure is configured to position the magnetic cylinder with respect to the straight rounded edge so that a curved face of the magnetic cylinder is substantially coextensive with a curved profile of the straight rounded edge of the device housing.

12. The self-aligning connector of claim 10 wherein the mounting structure is configured to position the magnetic cylinder so that the straight rounded edge of the device housing wraps around at least a portion of a curved face of the magnetic cylinder.

13. The self-aligning connector of claim 10 wherein the magnetic cylinder has a radius of curvature that is substantially equal to a radius of curvature of the straight rounded edge of the device housing.

14. The self-aligning connector of claim 10 wherein the magnetic cylinder has a diameter that is slightly smaller than a thickness of the device housing.

15. The self-aligning connector of claim 10 wherein the magnetic cylinder has an axial magnetic orientation and wherein the mounting structure is configured to fix the magnetic cylinder with respect to the device housing.

16. The self-aligning connector of claim 10 wherein the magnetic cylinder has a diametric magnetic orientation and wherein the mounting structure is configured to allow the magnetic cylinder to rotate along its axis with respect to the device housing.

17. A device having a straight rounded edge that is magnetically interconnectable with an other device so as to permit hinge-like movement of the device at the straight rounded edge while maintaining a magnetic interconnection, the device comprising:

a generally cuboid-shaped housing having a surface that is either of a sidewall of the housing and a corner adjoining two adjacent faces of the housing, the surface being straight due to the generally cuboid shape of the housing but having a curved transverse cross section and defining a straight rounded edge;

two self-aligning connectors, spaced apart from one another, along the straight rounded edge of the housing, each of the self-aligning connectors including;
