Abstract

Abstract A Christmas tree illuminated by a multiplicity of optic fiber sprays is provided in which an illuminator or light source is positioned in the base of the Christmas tree and bundled separately encapsulated fiber optic conduits extend upwardly from the base along the tree trunk. These fiber optic conduits branch out from the bundle along the tree trunk to extend laterally along the branches of the tree. The conduits terminate in a spray of optical fibers to provide a radiant multiplicity of pin pointlike ornamental lights over the entire tree.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 334 words
An artificial Christmas tree illuminated by optic fiber sprays, comprising, a hollow base for the tree; a plastic artificial Christmas tree mounted on the base, said tree having a central trunk extending upwardly from the base and a plurality of branches extending laterally from the trunk, said branches having imitiation foliage thereon; an assemblage of flexible optic fiber conduits, each said conduit comprising a multiplicity of generally axially aligned flexible optic fibers and means retaining the multiplicity of fibers together as a separate and discrete bundle, said conduits being in part disposed axially relative the trunk of the tree and being fixed in positions about the tree trunk at several locations, such that the assemblage substantially encloses the tree trunk adjacent the base and said assemblage of conduits extends into the base; said conduits extending laterally from said assemblage above the base at locations generally corresponding to the location of branches on the tree, each end of each such conduit having the fibers therein extending in an restrained manner beyond said retaining means, and said flexible fibers projecting in random configurations under their own weight and tensile strength to define sprays of separate optic fibers interspersed among the branches and foliage of the tree; a support engaging said assemblage of conduits extending into the base and closely gathering the conduits in a fixed position therewithin to define a generally planar fiber optic termination surface, said tree trunk being enclosed within the group of conduits also being held in position by said same support such that said tree and said conduits are held together as a unit; a light source positioned in the base adjacent the termination and directed to project light onto the termination surface; a color wheel within the base positioned between the light source and the termination surface; and means for rotating the color wheel such that the sprays of fibers produce the effect of a multicolored and changing multiplicity of pinpoint-like lights which emerge from within the foliage of the tree.
Claim 2
Dependent Claim 334 words
An artificial Christmas tree illuminated by optic fiber sprays, comprising, a hollow base for the tree; a plastic artificial Christmas tree mounted on the base, said tree having a central trunk extending upwardly from the base and a plurality of branches extending laterally from the trunk, said branches having imitiation foliage thereon; an assemblage of flexible optic fiber conduits, each said conduit comprising a multiplicity of generally axially aligned flexible optic fibers and means retaining the multiplicity of fibers together as a separate and discrete bundle, said conduits being in part disposed axially relative the trunk of the tree and being fixed in positions about the tree trunk at several locations, such that the assemblage substantially encloses the tree trunk adjacent the base and said assemblage of conduits extends into the base; said conduits extending laterally from said assemblage above the base at locations generally corresponding to the location of branches on the tree, each end of each such conduit having the fibers therein extending in an restrained manner beyond said retaining means, and said flexible fibers projecting in random configurations under their own weight and tensile strength to define sprays of separate optic fibers interspersed among the branches and foliage of the tree; a support engaging said assemblage of conduits extending into the base and closely gathering the conduits in a fixed position therewithin to define a generally planar fiber optic termination surface, said tree trunk being enclosed within the group of conduits also being held in position by said same support such that said tree and said conduits are held together as a unit; a light source positioned in the base adjacent the termination and directed to project light onto the termination surface; a color wheel within the base positioned between the light source and the termination surface; and means for rotating the color wheel such that the sprays of fibers produce the effect of a multicolored and changing multiplicity of pinpoint-like lights which emerge from within the foliage of the tree.
Claim 3
Dependent Claim 39 words
An artificial Christmas tree illuminated by optic fiber sprays in accordance with claim 1, including a motor and drive mechanism adapted to rotate as a unit both the tree and fiber conduit assemblage as well as the color wheel.
Claim 4
Dependent Claim 31 words
An artificial Christmas tree illuminated by optic fiber sprays in accordance with claim 1, in which the fibers extend beyond said retaining means for a length in excess of two inches.
Claim 5
Dependent Claim 21 words
An artificial Christmas tree illuminated by optic fiber sprays in accordance with claim 1, in which the fibers are glass fibers.
Claim 6
Dependent Claim 21 words
An artificial Christmas tree illuminated by optic fiber sprays in accordance with claim 1, in which the fibers are plastic fibers.
