Illuminated chart holder
First Claim
1. An illuminated chart holder comprising, in combination:
- a plate assembly, said plate assembly having upper and lower light transmitting plates, said upper light transmitting plate having a flat top surface and a flat bottom surface, and said lower light transmitting plate having a flat bottom surface and a flat top surface generally spaced from direct contact with the flat bottom surface of the upper light transmitting plate, with said flat top surface of said upper light transmitting plate being generally parallel to said flat bottom surface of said lower light transmitting plate, said plate assembly having side edge portions covered by light reflective material, and with said assembly of said upper light transmitting plate and said lower light transmitting plate having a display portion and a light source pocket;
at least one light reflecting surface disposed adjacent said bottom plate in said light source pocket;
at least one bulb of a first emission color disposed in the light source pocket of said plate assembly; and
,at least one bulb of a second emission color disposed in the light source pocket of said plate assembly.

Abstract
An illuminated chart holder for aircraft use has upper and lower light transmitting plates, the upper plate having a flat top surface and a concave-shaped bottom surface, and the lower plate having a flat bottom surface and a convex-shaped top surface, which is shaped to mate with, but to be spaced from, the bottom surface of the upper plate, with the top surface of the upper plate being generally parallel to the bottom surface of the lower plate, the plate assembly being covered on all four sides with reflecting material, and with the assembly of plates having a display portion and a light source pocket; at least one light reflecting surface either above or below the bottom plate in the light source pocket; at least two bulbs of a first color (e.g. white) and at least two bulbs of a second color (e.g. ANVIS green) in the light source pocket; and variable resistors connected to control intensity of the lights.

13. An illuminator for providing information to an aircraft operator, said illuminator comprising:
-
a plate assembly, said plate assembly having upper and lower light transmitting plates, said upper light transmitting plate having a flat top surface and a concave-shaped bottom surface, and said lower light transmitting plate having a flat bottom surface and a convex-shaped top surface, the convex-shaped top surface being shaped to generally mate with, but to be generally spaced from direct contact with, the shaped bottom surface of the upper light transmitting plate, with said flat top surface of said upper light transmitting plate being generally parallel to said flat bottom surface of said lower light transmitting plate, said plate assembly having side edge portions covered by light reflecting material, and with said assembly of said upper light transmitting plate and said lower light transmitting plate having a display portion and a light source pocket; at least one light reflecting surface disposed adjacent said bottom plate in said light source pocket; two bulbs of a first color and two bulbs of a second color disposed within four holes in said lower plate, respectively; a first rheostat connected to control intensity of light emitted from said bulbs of a first color; and a second rheostat connected to control intensity of light emitted from said bulbs of a second color. - View Dependent Claims (14, 15, 16, 17, 18)
