Abstract

An artificial tree has a central trunk, a number of main branches suspended from an upper portion of the trunk in a downwardly and outwardly inclined orientation, and a preformed tree top section extending upwardly from the upper portion of the trunk. Each main branch includes a number of sub-branch clusters and a bundle of fiber optic conduits which terminate in the sub-branches. The bundles of fiber optic conduits are received in an opaque enclosure housing a high intensity light source, which enclosure is attached to the upper portion of the trunk. Electric lights are disclosed as an alternative means to illuminate the tree. The trunk includes upwardly open hook elements which receive pin elements within the interior of rigid support members of the main branches. Each sub-branch cluster is pivotally connected to an associated rigid support member to articulate between a collapsed position for storage and shipping, and an extended position for display.

wherein each main branch includes a set of fiber optic conduits, each conduit having a first end portion terminating in one of said clusters of sub-branches, having an intermediate portion extending along said length of said support member of said main branch, and having a second end portion;

a source of light is connected to said central trunk member, said source of light being enclosed in an opaque enclosure;

said opaque enclosure having a number of openings suitable to permit the passage of light therethrough, said source of light being suitable to project light through said openings in said opaque enclosure; and

fiber optic conduit retainers suitable to releasably retain said second end portions of said sets of fiber optic conduits in alignment with said openings in said opaque enclosure to expose said second end portions of said sets of fiber optic conduits to light emitted from said source of light.

2. An artificial tree as in claim 1, wherein:

said central trunk member further comprises a top portion and said artificial tree further comprises a pre- formed tree-top portion being removably attachable to said top portion of said central trunk member;

said tree-top portion includes

a support member having bottom portion,

a number of sub-branches disposed along a length of said support member,

a set of fiber optic conduits, each fiber optic conduit having a first end portion terminating in one of said sub-branches of said tree-top portion, having an intermediate portion extending along said length of said support member of said tree-top portion, and having a second end portion; and

one of said fiber optic conduit retainers connected to said central trunk member being suitable to releasably retain said second end portions of said set of fiber optic conduits of said tree-top portion in alignment with one of said openings in said opaque enclosure to expose said second end portions of said set of fiber optic conduits of said tree-top portion to light emitted from said source of light.

3. An artificial tree as in claim 1, wherein said means to support said bottom portions of said main branches further comprises a lower support connected to said central trunk member below a top portion thereof, said bottom portions of said support members of said main branches contacting said lower support, and said lower support being spaced radially from said vertical longitudinal axis of said central trunk member a distance sufficient to support said main branches at said second predetermined perpendicular distance from said vertical longitudinal axis.

4. An artificial tree as in claim 3, wherein said means to removably mount said main branches to said central trunk member comprises generally upwardly-open support hooks connected to said central trunk member, said support hooks being radially outwardly spaced from and being angularly disposed around said vertical longitudinal axis of said central trunk member and each main branch comprising a pin member fixedly connected to said top portion of said main branch, said support hooks being suitable to receive said pin members of said main branches.

5. An artificial tree as in claim 1, further comprising a pre-formed tree-top portion, said tree-top portion being removably attachable to a top portion of said central trunk member.

6. An artificial tree as in claim 2, wherein said bottom portion of said support member of said tree-top portion encloses said set of fiber optic conduits.

7. An artificial tree as in claim 1, wherein:

said opaque enclosure includes a top portion having said openings therein;

said fiber optic conduit retainers are integrally formed with said opaque enclosure, each fiber optic conduit retainer surrounds one of said openings and is sized and shaped to closely receive and releasably retain one of said second end portions of said sets of fiber optic conduits.

8. An artificial tree as in claim 7, wherein:

said means to removably mount said main branches to said central trunk member comprises generally upwardly-open support hooks integrally formed with said opaque enclosure, said support hooks being radially outwardly spaced from and angularly disposed around said vertical longitudinal axis of said central trunk member and each main branch comprising a pin member fixedly connected to said top portion of said main branch, said support hooks being suitable to receive said pin members of said main branches.

9. An artificial tree as in claim 1, further comprising:

an optical disc disposed between said source of light and said second end portions of said sets of fiber optic conduits, said optical disc being enclosed within said opaque enclosure; and

a motor mechanically connected to said optical disc, said motor being suitable to rotate said optical disc with respect to said sets of fiber optic conduits; and

said optical disc including means to vary the characteristics of light projected onto said fiber optic conduits.

10. An artificial tree as in claim 9, wherein:

said opaque enclosure includes a top portion having said openings therein;

said fiber optic conduit retainers are integrally formed with said opaque enclosure, each fiber optic conduit retainer surrounds one of said openings and is sized and shaped to closely receive and releasably retain one of said second end portions of said sets of fiber optic conduits;

said openings and retainers being regularly angularly spaced about an axis of rotation of said optical disc.

11. An artificial tree, comprising:

(a) a support structure;
