Abstract

A binocular/goggle stereo vision device is provided which when worn on the head of a person will send stereoscopic images and stereophonic sounds directly to the eyes and ears of the person. The stereoscopic images are carried by a pair of liquid crystal displays while the stereophonic sounds are carried by a pair of earphones.

Claims

1. A stereo vision device which comprises:

(a) a band member adapted to be worn on the head of a person;

(b) an optical unit carried on said band member and adapted to be used by both eyes of the person;

(c) a pair of liquid crystal displays disposed in a side by side relationship in said optical unit, each of said displays adapted to receive one portion of stereoscopic images and disposed along a line of sight associated with one of the eyes of the person so as to supply three dimensional images to the eyes;

(d) a pair of earphones, each of said earphones carried on said band member adjacent to an ear of the person to receive one portion of stereophonic sounds; and

(e) a remote receiver/power supply pack for receiving stereo video signals and sending the stereoscopic images to said liquid crystal displays and receiving stereo audio signals and sending the stereophonic sounds to said earphones, wherein said optical unit is a pair of binoculars with a pair of adjustable eye pieces in which each said eye piece includes;

(f) an internally threaded sleeve rotatably mounted to housing of said binoculars;

(g) an externally threaded hollow shank engagably carried within said sleeve, said shank having a longitudinal slot therein; and

(h) a finger extending internally from the housing into the slot in said shank to prevent said shank from rotating with said sleeve but allowing said shank to move in and out with respect to the housing.

2. A stereo vision device which comprises:

(a) a band member adapted to be worn on the head of a person;

(b) an optical unit carried on said band member and adapted to be used by both eyes of the person;

(c) a pair of liquid crystal displays disposed in a side by side relationship in said optical unit, each of said displays adapted to receive one portion of stereoscopic images and disposed along a line of sight associated with one of the eyes of the person so as to supply three dimensional images to the eyes;

(d) a pair of earphones, each of said earphones carried on said band member adjacent to an ear of the person to receive one portion of stereophonic sounds; and

(e) a remote receiver/power supply pack for receiving stereo video signals and sending the stereoscopic images to said liquid crystal displays and receiving stereo audio signals and sending the stereophonic sounds to said earphones, wherein said optical unit is a pair of binoculars with a pair of adjustable eye pieces in which each said eye piece includes;

(f) an internally threaded sleeve rotatably mounted to housing of said binoculars;

(g) an externally threaded hollow shank engagably carried within said sleeve, said shank having a longitudinal slot therein; and

(h) a finger extending internally from the housing into the slot in said shank to prevent said shank from rotating with said sleeve but allowing said shank to move in and out with respect to the housing wherein the housing of said binoculars is adjustable with respect to said band member by a track assembly; and

(i) a stationary arm member extending downwardly from end of the track assembly and threadably extending through the threaded hole so that when said screw is rotated the track arm will move on the track assembly for a fine adjustment for said binoculars.
