Abstract

A toy object has an articulated shell structure which can change from a three-dimensional, polyhedral shape into a flattened shape. A biasing device applies force to the shell, that force tending to urge the shell structure into the three-dimensional, polyhedral shape. A holding device holds the shell structure in the flattened shape in opposition to the force applied by the biasing device, and a regulator regulates the period of time for which the holding device holds the shell structure in its flattened shape.

Claims

1. A toy object, comprising:

an articulated shell structure having a top cap, a bottom cap, and at least three fingers connecting said top cap and said bottom cap in a manner such that said articulated shell structure can selectively change from a three-dimensional, polyhedral shape into a flattened shape as said top cap and said bottom cap move together along a central axis;

an elastic member which is attached to at least two of said fingers, the elastic member applying a force to said fingers, the force tending to urge said shell structure into a three-dimensional, polyhedral shape;

a releasable lock which, when the shell structure is deformed to said flattened shape, applies a restraining force to said top cap and said bottom cap, the restraining force holding said shell structure in said flattened shape in opposition to the force applied by said elastic member; and

a variable timer which causes said releasable lock to apply the restraining force to the shell structure only during a period of time which can be varied, wherein after the period of time the variable timer causes said restraining force not to be applied, and the elastic member thereby urges said shell structure into the three-dimensional, polyhedral shape.

2. A toy object, comprising:

an articulated shell structure having a top cap, a bottom cap, and at least three fingers connecting said top cap and said bottom cap in a manner such that said articulated shell structure can selectively change from a three-dimensional, polyhedral shape into a flattened shape as said top cap and said bottom cap move together along a central axis;

an elastic member which surrounds said central axis and which is attached to at least three of said fingers, the elastic member applying a force to at least some of said fingers, the force tending to urge said shell structure into a three-dimensional, polyhedral shape;

a releasable lock which applies a restraining force to said top cap and said bottom cap, the restraining force holding said shell structure in said flattened shape in opposition to the force applied by said elastic member; and

a variable timer which causes said releasable lock to apply the restraining force to the shell structure only during a predetermined period of time,

wherein after the predetermined period of time the variable timer causes said restraining force not to be applied, and the elastic member thereby urges said shell structure into the three-dimensional, polyhedral shape.

3. A toy object as in claim 2, wherein said releasable lock comprises:

a suction cup attached to said top cap, said suction cup facing into said toy object; and

a surface opposing said suction cup,

wherein said suction cup is positioned such that as said shell structure deforms from the three-dimensional, polyhedral shape into the flattened shape and said top and said bottom caps move together, said suction cup and said surface move together into sealing engagement, and have a volume therebetween.

4. A toy object as in claim 3, wherein said variable timer comprises an adjustable valve which regulates a flow of air into the volume between said first suction cup and said surface.

5. A toy object as in claim 2, wherein said suction cup has an axial bore in fluid communication with a transverse bore, the transverse bore communicating with a surroundings, said valve comprising:

a valve handle;

a valve stem attached to said valve handle, said valve stem having an axial bore and a transverse bore communicating with said axial bore,

wherein said valve stem is disposed in said axial bore of said suction cup in a manner which allows said valve stem to rotate, said valve stem being dimensioned and disposed such that as said valve stem rotates in said axial bore, said transverse bore of said suction cup and said transverse bore of said valve stem come into registry, allowing fluid communication from the surroundings to the volume between the suction cup and the surface.

6. A toy object as in claim 2, wherein said surface opposing said suction cup comprises a second suction cup.

7. A toy object as in claim 2, wherein said at least three fingers are symmetrically disposed about said central axis.

8. A toy object as in claim 7, wherein said at least three fingers comprise six said fingers.

9. A toy object as in claim 2, wherein said elastic member lies in a plane.

10. A toy object as in claim 9, wherein said plane is perpendicular to said central axis.

11. A toy object as in claim 2, wherein said elastic member comprises at least one spring.

12. A toy object as in claim 8, wherein said elastic member comprises six springs.

13. A toy object as in claim 12, further comprising at least six rings, each said spring being connected at an end to a particular said ring, so that said six springs and said rings together form a hexagon.

14. A toy object as in claim 13, wherein each said ring comprises a bridle extending from that said ring to an associated said finger.

15. A toy object as in claim 2, wherein each said finger comprises a plurality of panels and a plurality of living hinges, said panels and said living hinges being arranged in alternation along a length of said finger.

16. A toy object as in claim 15, wherein each said finger is joined to said top cap by a first said living hinge and to said bottom cap by a second said living hinge.

17. A toy object as in claim 15, further comprising a plurality of bridles, each said bridle connecting the elastic member to an associated said living hinge.

18. A toy object as in claim 2, wherein said articulated shell structure has a perimeter, and further comprising a plurality of perimeter weights disposed on said perimeter.

19. A toy object as in claim 18, wherein said elastic member lies in a plane perpendicular to said central axis, and said perimeter weights are disposed in said plane.

20. A toy object as in claim 2, wherein said fingers and said bottom cap are formed as an integral unit.

21. A toy object, comprising:

an articulated shell structure having a top cap, a bottom cap, and at least three fingers connecting said top cap and said bottom cap in a manner such that said articulated shell structure can selectively change from a three-dimensional, polyhedral shape into a flattened shape;

biasing means for applying a force to at least some of said fingers, the force tending to urge said shell structure into the three-dimensional, polyhedral shape;

holding means for holding said shell structure in the flattened shape in opposition to the force applied by said biasing means; and

regulating means for regulating a period of time during which said holding means holds said shell structure in said flattened shape, so that said period of time during which said holding means holds said shell structure in said flattened shape can be varied.

22. A method of changing a configuration of a toy object, comprising the steps of:

providing the toy object, the toy object having an articulated shell structure deformable between a three-dimensional polyhedral shape and a flattened shape, a releasable lock which, when the shell structure is deformed to a position applies a restraining force to the shell structure to hold the shell structure in the position, and a variable timer which causes the releasable lock to apply the restraining force to the shell structure only during a period of time which can be varied;

applying a force to a portion of said shell structure, the force tending to urge the shell structure into the polyhedral shape;

holding the shell structure in the flattened shape using the releasable lock in opposition to the force applied; and

regulating a duration of said holding of the shell structure by the releasable lock in the flattened shape using the variable timer.
