Abstract
Abstract An educational device comprising a box having a mirror surface therein disposed at a predetermined angle and a viewing surface disposed above the angled mirror surface and containing two pairs of adjacent slots therein with one pair of slots being disposed in a row and being angled substantially parallel to the mirror surface while the other pair of slots are disposed in an adjacent row substantially parallel thereto. The slots are also disposed in columns so that one slot comprises a viewing slot and the corresponding slot in the other row comprises a display slot. Means, such as cubes having indicia on each face thereof are removably mountable in the display slots for providing a pair of visible adjacent images at the viewing slots.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
203 words
An educational device comprising a housing having a viewing surface, said viewing surface having a first pair of adjacent apertures therein disposed in a first row and a second pair of adjacent apertures therein disposed in a second row substantially parallel to said first row, said first and second rows being substantially adjacent, one aperture of said first pair of apertures being adjacent to one aperture of said second pair of apertures in a first column and the other aperture of said first pair of apertures being adjacent to said other aperture of said second pair of apertures in a second column; a substantially planar mirror surface disposed below said first pair of apertures at a predetermined angle relative to said first pair of apertures, said second pair of apertures being disposed in said viewing surface at an angle substantially equivalent to said mirror surface predetermined angle; and means removably mountable in said second pair of apertures for providing a pair of visible adjacent images at said first pair of apertures, the angle of reflection of said images with respect to said mirror surface enabling said incident images through said second pair of apertures to be visible through said first pair of apertures.
Claim 2
Dependent Claim
203 words
An educational device comprising a housing having a viewing surface, said viewing surface having a first pair of adjacent apertures therein disposed in a first row and a second pair of adjacent apertures therein disposed in a second row substantially parallel to said first row, said first and second rows being substantially adjacent, one aperture of said first pair of apertures being adjacent to one aperture of said second pair of apertures in a first column and the other aperture of said first pair of apertures being adjacent to said other aperture of said second pair of apertures in a second column; a substantially planar mirror surface disposed below said first pair of apertures at a predetermined angle relative to said first pair of apertures, said second pair of apertures being disposed in said viewing surface at an angle substantially equivalent to said mirror surface predetermined angle; and means removably mountable in said second pair of apertures for providing a pair of visible adjacent images at said first pair of apertures, the angle of reflection of said images with respect to said mirror surface enabling said incident images through said second pair of apertures to be visible through said first pair of apertures.
Claim 3
Dependent Claim
78 words
An educational device in accordance with claim 1 wherein said image providing means comprises a pair of multifaceted members, each member having indicia on each of the faces thereof, each of said members being individually removably mountable In one of said second pair of apertures with the face thereof containing the indicia whose image is to be visible through said corresponding aperture of said first pair of apertures directly covering said one of said second pair of apertures.
Claim 4
Dependent Claim
14 words
An educational device in accordance with claim 2 wherein said multifaceted members are cubes.
Claim 5
Dependent Claim
41 words
An educational device in accordance with claim 2 wherein said indicia on one of said multifaceted members has a predetermined relationship with respect to a corresponding indicia on the other of said multifaceted members, each face thereof having different indicia thereon.
Claim 6
Dependent Claim
20 words
An educational device in accordance with claim 1 wherein said housing further includes illuminating means for illuminating said mirror surface.
Claim 7
Dependent Claim
