Abstract

A doll head is disclosed having a magnetically adjustable facial contour, along with a method for assembling same. In one embodiment, the doll head includes a face mask support on which is mounted an elastically deformable face mask. Movable adjustment mechanisms and associated motors and power supplies for moving the adjustment mechanisms are disposed in the face mask support. Each adjustment mechanism generates an applied magnetic field. First magnets are affixed to an inner surface of the face mask, and second magnets in magnetic communication with the first magnets are slidably disposed on an exterior surface of the face mask support. The adjustment mechanisms selectively apply magnetic fields that slidably adjust position of the second magnets. As position of the second magnets slidably adjust, the first magnets move to a like extent. As the first magnets move, contour of the face mask adjusts to change expression of the doll head.

Claims

1. A doll head having a magnetically adjustable facial contour, the doll head comprising:

a face mask support;

a face mask mountable on the face mask support;

a first magnet connectable to the face mask; and

a second magnet connectable to the face mask support, the second magnet being adjustable over a range of positions and configured to magnetically couple with the first magnet,

whereby adjusting the second magnet from a first position of the range to a second position of the range causes the first magnet to move therewith, thereby causing movement of at least a portion of the face mask to which the first magnet is connected, and thereby alters the facial contour of the face mask from a first facial contour of the face mask to a second facial contour of the face mask.

2. The doll head of claim 1, further comprising an adjustment mechanism coupled to the second magnet for adjusting the second magnet over the range of positions.

3. The doll head of claim 2, further comprising a motor connectable to the adjustment mechanism for operating the adjustment mechanism.

4. The doll head of claim 3, further comprising a power supply connectable to the motor and the adjustment mechanism for supplying power to the motor and the adjustment mechanism.

5. The doll head of claim 1, wherein the face mask support defines a slot therethrough sized to slidably receive the second magnet for slidably adjusting the second magnet.

6. The doll head of claim 1, further comprising an eye element movably connected to the face mask support.

7. The doll head of claim 6, wherein the eye element is magnetically movable.

8. A doll head having a magnetically adjustable facial contour, the doll head comprising:

a face mask support defining a cavity therein and at least one slot therethrough;

a face mask mounted on the face mask support, the face mask having an interior surface and an exterior surface defining a facial contour; and

for each of the at least one slots;

a first magnet coupled to a guide means, the guide means received in the slot to guide the second magnet through a range of positions defined by the slot; and

a first magnet affixed to the interior surface of the face mask, the first and second magnets configured to be magnetically coupled with one another,

whereby adjusting the first magnet from a first position of the range to a second position of the range causes the second magnet to move therewith, thereby causing movement of at least a portion of the face mask to which the second magnet is connected, and thereby alters the facial contour of the face mask from a current facial contour to a different facial contour.

9. The doll head of claim 8, further comprising:

an adjustment mechanism magnetically coupled to the first magnet for adjusting the first magnet through the range of positions defined by the slot;

an electrically operable motor connected to the adjustment mechanism for electrically operating the adjustment mechanism; and

an electrical power supply electrically connected to the electric motor and the adjustment mechanism for supplying electricity to the electric motor and the adjustment mechanism.

10. The doll head of claim 9, wherein the electrical power supply is a battery.

11. The doll head of claim 10, wherein the battery is a rechargeable battery.

12. The doll head of claim 8, wherein the face mask support defines an eye socket therein.

13. The doll head of claim 12, further comprising:

a movable eye element disposed in the eye socket, the eye element having a magnetically responsive portion; and

a bi-directional adjustment mechanism magnetically coupled to the magnetically responsive portion of the eye element for moving the eye element bidirectioinally.

14. The doll head of claim 13, further comprising:

an electric motor connected to the bi-directional adjustment mechanism for electrically operating the bi-directional adjustment mechanism; and

an electrical power supply electrically connected to the electric motor for supplying electricity to the electric motor.

15. The doll head of claim 14, wherein the electrical power supply is a battery.

16. The doll head of claim 15, wherein the battery is a rechargeable battery.

17. The doll head of claim 8, wherein the face mask support includes a hinged jaw assembly movable between an open position and a closed position.

18. The doll head of claim 17, wherein the jaw assembly is magnetically operable.

19. The doll head of claim 17, wherein the jaw assembly is mechanically operable.

20. A method of assembling a doll head having a magnetically adjustable facial contour, comprising:

providing a face mask support;

mounting a face mask on the face mask support, the face mask having an interior surface and an exterior surface defining a facial contour;

connecting a first magnet to the face mask;

connecting a second magnet to the face mask support, the second magnet being to adjustable through a range of positions and configured to magnetically couple with the first magnet,

whereby adjusting the second magnet from a first position of the range to a second position of the range causes the first magnet to move therewith, thereby causing movement of at least a portion of the face mask to which the first magnet is connected, and thereby alters the facial contour of the face mask from a current facial contour to a different facial contour.
