Abstract
A viewer that creates an enhanced and immersive image is disclosed. Also disclosed is a novel collapsible viewer that assembles into a substantially rigid structure to maintain proper optical alignment of the lenses and the image(s). This viewer also excludes extraneous light, while allowing the user to focus the device to compensate for variations in eyesight of the users. Also disclosed is a novel means for interchanging images and locking them into optical alignment with the lenses of the viewer.

7. A box-like collapsible viewer comprising:
-
a front wall, said front wall having at least one lens receiving opening defined therein and a lens affixed thereto, said front wall having a bottom edge and a top edge, said front wall having two lateral edges, with at least one slit opening there through along each of said lateral edges of said front wall, a rear wall, said rear wall having at least one light admitting opening defined therein, said rear wall having top, bottom, right, and left edges, a bottom wall, said bottom wall being continuous with both said front and rear walls, along the respective bottom edges of said front and rear walls, a top wall, said top wall being continuous with said rear wall along said top edge of said rear wall, said top wall being attached to said front wall along at least a portion of said top edge of said front wall to define a collapsible box assembly, and a right side wall and a left side wall, said right and left side walls being continuous with said rear wall along right and left fold lines that define said right and left edges of said rear wall, respectively, said right and left side walls having outer edges that are opposite said right and left fold lines defined by right and left arcuate fold lines, said outer edges of said right and left side walls further having key means attached or integral thereto, said outer edges further having tongue flaps, said tongue flaps being continuous with said right and left side walls along said arcuate fold lines of said right and left side walls, said tongue flaps of said right and left side walls adapted to be folded inwardly along said right and left arcuate fold lines, said tongue flaps being positionable between said top and bottom walls of said box assembly, said tongue flaps further being positionable against said front wall of said box assembly, said key means of said right and left side walls being positionable in said slit openings of said front wall of said box assembly, said right and left side walls being of sufficient length such that said outer arcuate edges of said right and left side walls contact the inner face of said front wall, thereby forcing said front wall to conform to the profile of said outer arcuate edges and thereby predisposing the front wall to flex outwardly when the user presses said top and bottom walls together. - View Dependent Claims (8, 9, 10)
