Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
160 words
A marking display structure for a motor vehicle window, comprising: a light-permeable pattern provided on the inner surface of a glass membrane for a window of the motor vehicle; illuminating means for illuminating said pattern, said illuminating means comprising a luminescent lamp which comprises a light-permeable electrode layer, a rear electrode layer, and a luminescent layer interposed between said light-permeable electrode layer and said rear electrode, said light-permeable electrode being disposed in facing relationship with said pattern such that portions of said lamp are viewable through said pattern; and energizing means for energizing said lamp, said energizing means comprising a DC-AC converter, such that (a) when said lamp is not energized by said energizing means, said portions of said lamp are viewable with external illumination alone of said display structure, and (b) when said lamp is energized by said energizing means, said pattern is illuminated by said lamp, whereby said pattern is viewable without external illumination of said display structure.
Claim 2
Dependent Claim
160 words
A marking display structure for a motor vehicle window, comprising: a light-permeable pattern provided on the inner surface of a glass membrane for a window of the motor vehicle; illuminating means for illuminating said pattern, said illuminating means comprising a luminescent lamp which comprises a light-permeable electrode layer, a rear electrode layer, and a luminescent layer interposed between said light-permeable electrode layer and said rear electrode, said light-permeable electrode being disposed in facing relationship with said pattern such that portions of said lamp are viewable through said pattern; and energizing means for energizing said lamp, said energizing means comprising a DC-AC converter, such that (a) when said lamp is not energized by said energizing means, said portions of said lamp are viewable with external illumination alone of said display structure, and (b) when said lamp is energized by said energizing means, said pattern is illuminated by said lamp, whereby said pattern is viewable without external illumination of said display structure.
Claim 3
Dependent Claim
32 words
A marking display structure as in claim 1, wherein said pattern comprises light-permeable portions corresponding to said pattern formed in a light-impermeable film disposed on the inner surface of said glass membrane.
Claim 4
Dependent Claim
20 words
A marking display structure as in claim 1, wherein said pattern is formed of light-permeable and light-impermeable films laminated together.
Claim 5
Dependent Claim
78 words
A marking display structure according to claim 1, further comprising a cover member having a recessed portion and a peripheral flange-like portion, and holding means provided on said cover member for holding said DC-AC converter, wherein said illuminating means is attached to the inner surface of said recessed portion, and said cover member is attached at said peripheral flange-like portion to the inner surface of said glass membrane, with said illuminating means being accommodated in said recessed portion.
Claim 6
Dependent Claim
26 words
A marking display structure according to claim 1, further comprising holding means provided on an interior trim of the motor vehicle for holding said DC-AC converter.
Claim 7
Dependent Claim
36 words
A marking display structure according to claim 1, further comprising holding means provided on a bracket attached to an opening flange of a rear pillar outer panel of the motor vehicle for holding said DC-AC converter.
Claim 8
Dependent Claim
22 words
A marking display structure according to claim 1, further comprising a light-permeable colored film interposed between said light-permeable pattern and said lamp.
Claim 9
Dependent Claim
136 words
A marking display structure for a motor vehicle, comprising: illuminating means for illuminating a pattern, comprising a luminescent lamp having a light-permeable electrode layer, a rear electrode layer, and a luminescent layer interposed between said light-permeable layer and said rear electrode layer; a light-permeable pattern provided on the surface of said luminescent lamp such that portions of such lamp are viewable through said pattern; and energizing means for energizing said lamp, said energizing means comprising a DC-AC converter, such that (a) when said lamp is not energized by said energizing means, said portions of said lamp are viewable with external illumination alone of said display structure and (b) when said lamp is energized by said energizing means, said pattern is illuminated by said lamp, whereby said pattern is viewable without external illumination of said display structure.
Claim 10
Dependent Claim
136 words
A marking display structure for a motor vehicle, comprising: illuminating means for illuminating a pattern, comprising a luminescent lamp having a light-permeable electrode layer, a rear electrode layer, and a luminescent layer interposed between said light-permeable layer and said rear electrode layer; a light-permeable pattern provided on the surface of said luminescent lamp such that portions of such lamp are viewable through said pattern; and energizing means for energizing said lamp, said energizing means comprising a DC-AC converter, such that (a) when said lamp is not energized by said energizing means, said portions of said lamp are viewable with external illumination alone of said display structure and (b) when said lamp is energized by said energizing means, said pattern is illuminated by said lamp, whereby said pattern is viewable without external illumination of said display structure.
