Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
184 words
An illuminable safety and vehicle function display device, comprising: a casing having therein a first group of cells and a second group of cells, each of said first group of cells being connected to one of said second group of cells through an opening formed in said casing; a labelled display plate covering said first group of cells to allow the caution letters thereon to be positioned on the cells respectively; a figured display plate covering said second group of cells; a light shielding plate disposed between said figured display plate and said second group of cells, said shielding plate being formed therein with a plurality of translucent portions each of which is located at a given part of said figured display plate and is arranged on one of said second group of cells; and a single light source disposed in a portion which is open to said opening formed in the casing, whereby a given caution letter of said labelled display plate and also the corresponding translucent portion of said shielding plate are illuminated when said light source is energized to light up.
Claim 2
Dependent Claim
184 words
An illuminable safety and vehicle function display device, comprising: a casing having therein a first group of cells and a second group of cells, each of said first group of cells being connected to one of said second group of cells through an opening formed in said casing; a labelled display plate covering said first group of cells to allow the caution letters thereon to be positioned on the cells respectively; a figured display plate covering said second group of cells; a light shielding plate disposed between said figured display plate and said second group of cells, said shielding plate being formed therein with a plurality of translucent portions each of which is located at a given part of said figured display plate and is arranged on one of said second group of cells; and a single light source disposed in a portion which is open to said opening formed in the casing, whereby a given caution letter of said labelled display plate and also the corresponding translucent portion of said shielding plate are illuminated when said light source is energized to light up.
