Abstract

Abstract A light-passing decorative object made of light-passing synthetic resin is characterized in that a film piece on which letters, patterns or the like are displayed in such a manner as to be seen therethrough is intimately bonded to a notch-cut back side of a light-passing decorative member. The decorative member is provided a back side thereof with a face brightening device. The face brightening device has optical fibers arranged in parallel relation. The optical fibers being provided with a notched portion so as to be brightened. One ends of the optical fibers are bundled to form a bundle portion and attached to a coupler for coupling to a light source.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 176 words
A light-passing decorative object comprising: a light-passing decorative member made of a light-passing synthetic resin, said decorative member including a notch-cut back side; a film piece having indicia which is viewable through the film piece, the film piece being bonded to the notch-cut back side of the decorative member; and a face brightening device which illuminates the film piece, the brightening device including (a) a plurality of optical fibers having a bundled end, (b) a coupler for coupling the bundled end of the optical fibers to a light source, and (c) an illuminating surface attached to the decorative member with the film piece between the illuminating surface and the back side of the decorative member, the illuminating surface being formed by the optical fibers which are arranged in parallel relation and provided with notched portions through which light conducted through the optical fiber passes and illuminates the film piece, the indicia being formed by openings in a no-light-passing layer applied on the film piece and wherein a light-passing metallic layer is attached to the film piece.
Claim 2
Dependent Claim 176 words
A light-passing decorative object comprising: a light-passing decorative member made of a light-passing synthetic resin, said decorative member including a notch-cut back side; a film piece having indicia which is viewable through the film piece, the film piece being bonded to the notch-cut back side of the decorative member; and a face brightening device which illuminates the film piece, the brightening device including (a) a plurality of optical fibers having a bundled end, (b) a coupler for coupling the bundled end of the optical fibers to a light source, and (c) an illuminating surface attached to the decorative member with the film piece between the illuminating surface and the back side of the decorative member, the illuminating surface being formed by the optical fibers which are arranged in parallel relation and provided with notched portions through which light conducted through the optical fiber passes and illuminates the film piece, the indicia being formed by openings in a no-light-passing layer applied on the film piece and wherein a light-passing metallic layer is attached to the film piece.
Claim 3
Dependent Claim 34 words
A light-passing decorative object as claimed in claim 1 characterized in that the optical fibers have a second bundled end attached to the coupler for coupling the second bundled end to a light source.
Claim 4
Dependent Claim 39 words
A light-passing decorative object as claimed in claim 1 characterized in that the optical fibers have a second bundled end and a second coupler to which the second bundled end is attached for coupling to a second light source.
Claim 5
Dependent Claim 25 words
A light-passing decorative object as claimed in claim 1, characterized in that the openings of the no-light-passing layer are punched out from the no-light-passing layer.
Claim 6
Dependent Claim 39 words
A light-passing decorative object as claimed in claim 1, characterized in that a second light-passing film piece overlaps the no-light-passing layer so that the no-light-passing layer is sandwiched between the first mentioned film piece and the second film piece.
Claim 7
Dependent Claim 180 words
A light-passing decorative object comprising: a light-passing decorative member made of a light-passing synthetic resin, said decorative member including a notch-cut back side; a film piece having indicia which is viewable through the film piece, the film piece being bonded to the notch-cut back side of the decorative member; and a face brightening device which illuminates the film piece, the brightening device including (a) a plurality of optical fibers having a bundled end, (b) a coupler for coupling the bundled end of the optical fibers to a light source, and (c) an illuminating surface attached to the decorative member with the film piece between the illuminating surface and the back side of the decorative member, the illuminating surface being formed by the optical fibers which are attached in parallel relation and provided with notched portions through which light conducted through the optical fiber passes and illuminates the film piece, the indicia being formed by openings in a no-light-passing layer applied on the film piece and, wherein said face brightening device includes a reflecting film provided at a back side thereof.
Claim 8
Dependent Claim 180 words
A light-passing decorative object comprising: a light-passing decorative member made of a light-passing synthetic resin, said decorative member including a notch-cut back side; a film piece having indicia which is viewable through the film piece, the film piece being bonded to the notch-cut back side of the decorative member; and a face brightening device which illuminates the film piece, the brightening device including (a) a plurality of optical fibers having a bundled end, (b) a coupler for coupling the bundled end of the optical fibers to a light source, and (c) an illuminating surface attached to the decorative member with the film piece between the illuminating surface and the back side of the decorative member, the illuminating surface being formed by the optical fibers which are attached in parallel relation and provided with notched portions through which light conducted through the optical fiber passes and illuminates the film piece, the indicia being formed by openings in a no-light-passing layer applied on the film piece and, wherein said face brightening device includes a reflecting film provided at a back side thereof.
