Illuminated pointer enabling independent pointing on two scales simultaneously
View Patent ↗An illuminated pointer includes an outer pointer that surrounds an inner pointer. The outer pointer extends from a base and is generally elliptical. The inner pointer extends from the base into the void of the outer pointer. The illuminated pointer utilizes a single light source for illuminating both the outer and inner pointer. The inner pointer provides easier reading of a dual scale gauge such as with a speedometer having both English and Metric speed scales.
1. An illuminated pointer assembly for an instrument panel comprising:
a shaft;
a body portion supported atop said shaft, said body portion including a light reflecting surface;
a first pointer having a first leg and a second leg extending from said body portion in a first direction; and
a second pointer extending in the first direction from said body portion between said first and second legs, wherein said light reflecting surface includes a first light reflecting surface to direct light into said first leg, a second light reflecting surface to direct light into said second leg and a third light reflecting surface to direct light into said second pointer, wherein each of said first, second and third reflecting surfaces direct light generally in the first direction.
2. The assembly as recited in claim 1 , wherein said first and second legs are joined at a pointer segment opposite said body portion.
3. The assembly as recited in claim 1 , wherein said light reflecting surface is disposed along an axis of rotation defined by said shaft.
4. The assembly as recited in claim 1 , wherein said light reflecting surface is on a side of said shaft common to said first pointer and said second pointer.
5. The assembly as recited in claim 1 , wherein said light reflecting surface is on a side of said shaft opposite said first pointer and said second pointer.
6. The assembly as recited in claim 1 , wherein said first and second legs include a top surface, a bottom surface and two sides between said top surface and said bottom surface, said top surface and said bottom surface including a width between each of said two sides, wherein said width of said top surface is greater than a width of said bottom surface.
7. The assembly as recited in claim 6 , including a reflective coating disposed on at least a portion of said bottom surface.
8. The assembly as recited in claim 1 , wherein said pointer rotates about an axis, and said first, second and third reflecting surfaces direct light toward a common side of said axis.
9. An illuminated pointer assembly including:
a body;
a first pointer extending from said body in a first direction and including a tip and an opening;
a second pointer extending from said body in said first direction partially into said opening;
a first light reflecting surface on the body to direct light into the first pointer in the first direction; and
a second light reflecting surface on the body to direct light into the second pointer.
10. The assembly as recited in claim 9 , including a shaft extending from said body transverse to said first pointer and said second pointer, said shaft mountable for rotation about a first axis.
11. The assembly as recited in claim 10 , wherein said shaft is hollow and directs light onto said light reflecting surface.
12. The assembly as recited in claim 9 , including a third light reflecting surfaces directing light into said first pointer.
13. The assembly as recited in claim 12 , wherein said first pointer includes a first leg and a second leg joined extending on one end from said body and jointed on another end at said tip, wherein said first light reflecting surface directs light into said first leg and said third light reflecting surface directs light into said second leg.
14. The assembly as recited in claim 13 , wherein said second light reflecting surface directs light into said second pointer.
15. The assembly as recited in claim 9 , wherein said pointer rotates about an axis, and said first and second light reflecting surfaces direct light toward a common side of said axis.
