| Abstract: |
A fiber optic Christmas tree is set forth wherein a conical Christmas tree of traditional configuration is presented wherein a series of parallel planes intersect the conical configuration to define the series of stacked, segments of the tree. The segments include a hollow cylindrical axially aligned transparent conduit housing an elongate light source. Each segment of the conical Christmas tree includes radially through-extending apertures defining a matrix therethrough wherein the exterior openings of the apertures accept a like number of fiber optic wands wherein a terminal end of the wands include a series of flared fiber optic fibers extending therefrom to simulate foliage of the tree wherein each of the wands is formed of various colorations to present a desired effect upon viewing of the tree. The segments are aligned relative to one another by the transparent conduit and by upstanding bosses formed to upper surfaces of the segments aligned with confronting grooves of the next adjacent upper segment to maintain the rigidity of the tree once erected.

What is claimed as being new and desired to be protected by Letters Patent of the United States is as follows:
1. A fiber optic Christmas tree comprising,
- a conical Christmas tree including a plurality of conical segments, each segment formed with an axially aligned cylindrical central chamber, and
- a plurality of light conducting conduits radially directed from said central chamber to an exterior surface of each segment, and
- a light source positionable axially of said Christmas tree when said segments are stacked upon one another, and
- a plurality of fiber optic members selectively positionable within said conduits to visually direct light from said light source through said fiber optic members, and
- wherein the fiber optic members are formed in a variety of colors, and
- wherein a cap socket is positionable on an uppermost segment of the Christmas tree when the segments are stacked upon one another, wherein the cap socket includes an electrical socket for electrical association of the light source with a base segment wherein said base segment is positionable at the lowermost terminal end of the segments when stacked, and
- wherein a transparent cylindrical diffuser tube is positionable through the axial chamber of each of the plurality of segments to effect diffusion of the light source and provide stability to the stack of segments, and
- wherein each conical segment is defined by a parallel upper and lower surface, and wherein each upper surface includes at lease one arcuate tab directed upwardly and orthogonally relative to the upper surface, and each lower surface contains a cylindrical groove to slidingly receive a tab from a lowermost segment.
