Abstract

A targeting device comprising a transparent casing having a circumferential wall formed with circumferentially aligned openings. A transparent lens is enclosed by and in firm contact with the circumferential wall of the casing, has it circumferential surface disposed directly opposite the opening in the casing, and has one of its plane surfaces formed with a reticle of reflective material. Light emitting diodes are disposed in the casing openings and are connected to a power source. Coating material is provided on the casing for inhibiting light from escaping from the casing, while intensifying reflection of light from the diodes into the casing and then into the lens for illumination of the reticle.

Claims

1. A targeting device comprising:

a transparent casing having a circumferential wall

the circumferential wall having inner and outer surfaces and being formed with at least one opening,

a transparent lens having two opposite plane surfaces and a circumferential surface,

the lens being enclosed by and in firm contact with the inner surface of the circumferential wall of the casing, having its circumferential surface disposed directly opposite said opening, and having one of its plane surfaces formed with a reticle of reflective material, at least one light source, said light source being disposed in said opening,

an energy source connected to said light source, and

coating means on the casing for inhibiting light from escaping from the casing while intensifying reflection of light from the light source into the casing between the inner and outer surfaces of said circumferential wall and then into the lens by way of said circumferential surface for illumination of the reticle.

2. The device of claim 1 wherein the casing is tubular and said at least one opening includes three opening spaced from one another in said circumferential wall, said at least one light source includes three light sources, one of said three light sources being disposed in each of the openings, the energy source is connected to each of the light sources, the lens is circular and has said circumferential surface disposed directly opposite the openings and in firm contact with the inner surface of the circumferential wall of the casing, and the coating means intensifies reflection of light from the light sources into the casing.

3. The device of claim 2 wherein the light sources are light emitting diodes.

4. The device of claim 1 wherein the reticle is formed by red paint.

5. The device of claim 1 wherein the inner surface of the circumferential wall of the casing is formed with a seat for the lens.

6. The device of claim 1 wherein the coating means includes a layer of black paint on top of a layer of white paint.

7. The device of claim 1 wherein the casing and lens are formed by plastic material.

8. The device of claim 1 in combination with an archery bow having a central body portion wherein means are provided to secure the device to the central body portion of the bow including an arc-shaped brace attached to the outer surface of the circumferential wall of the casing.
