Abstract
An illuminable pointer assembly for an instrument panel includes a transparent or translucent base, a transparent or translucent pointer blade, and a hub mounted on the base and supporting the pointer blade. The assembly is miniaturized or capable of being miniaturized by integrating reflectors into a lower surface of the pointer blade to internally reflect light propagated upwardly through the base in a lateral direction to uniformly illuminate the pointer blade.
Claims20
An illuminable pointer assembly for an instrument panel, comprising:
- a transparent or translucent base having a shaft portion and a disc portion that is perpendicular to the shaft portion and located at an upper end of the shaft portion;
- a transparent or translucent pointer blade having a lower surface facing an upper surface of the disc portion of the base;
- and
- reflectors integrally defined at the lower surface of the pointer blade for internally reflecting light propagated upwardly through the base in a lateral direction through the pointer blade.
An illuminable pointer assembly for an instrument panel, comprising:
- a hub having a top and circumferential side wall, the hub rotatable about a central axis of the hub;
- a pointer blade having an arm section extending radially away from the hub, a tail section extending opposite the arm section away from the hub, and a hub section disposed within the circumferential side wall of the hub between the arm section and the tail section;
- and
- wherein the top of the hub has an elongate opening, and an upper portion of the pointer blade extends through the elongate opening such that there is no gap between the upper portion of the pointer blade and the elongate opening.
An illuminable pointer assembly for an instrument panel, comprising:
- a transparent or translucent base having a shaft portion and a disc portion perpendicular to the shaft portion;
- a transparent or translucent pointer blade;
- and
- a diffuser sheet including a light-scattering diffuser area disposed between the disc potion of the base and the pointer blade.
