Abstract

Abstract Disclosed is an educational device for dyslexic children which comprises a base, a shaft mounted on the base, a plurality of blocks mounted on the shaft for rotation relative to the base, and a mirror mounted on the base facing the shaft. Mirror-image and/or totally backwards indicia are carried by the blocks on at least one face of each of the blocks, whereby the blocks can be rotated to positions in which the indicia are reflected by the mirror.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 288 words
An educational device for dyslexic children, said device comprising: (a) a base; (b) a shaft mounted on said base; (c) a plurality of blocks mounted on said shaft for rotation relative to said base; (d) a mirror mounted on said base facing said shaft; (e) mirror-image alphabetic indicia carried by at least some of said blocks on at least one face of each of said at least some of said blocks in position to be directly visible to the user of said device, said indicia having a normal orientation when seen by normal children and a mirror-image orientation when seen by dyslexic children and said mirror-image indicia being the mirror-image of the form in which they are seen by non-dyslexic children, whereby said blocks can be rotated to positions in which said mirror-image indicia appear in normal orientation in said mirror, allowing the use of said device to compare the mirror-image indicia carried by said blocks with their mirror-images (that is, their normal appearance) in said mirror by simply turning the blocks so that the mirror-image indicia reflect in the mirror; and (f) totally backwards alphabetic indicia carried by said at least some of said blocks on at least one face of each of said at least some of said blocks, said totally backwards indicia and said mirror-image indicia on each of said at least some of said blocks being related so that, when the totally backwards indicium is directly visible, the corresponding mirror-image indicium is reflected in said mirror in its normal orientation, allowing the user of the device to compare directly the totally backwards indicia carried by said at least some of said blocks with their normal appearance in said mirror, since both are simultaneously visible.
Claim 2
Dependent Claim 288 words
An educational device for dyslexic children, said device comprising: (a) a base; (b) a shaft mounted on said base; (c) a plurality of blocks mounted on said shaft for rotation relative to said base; (d) a mirror mounted on said base facing said shaft; (e) mirror-image alphabetic indicia carried by at least some of said blocks on at least one face of each of said at least some of said blocks in position to be directly visible to the user of said device, said indicia having a normal orientation when seen by normal children and a mirror-image orientation when seen by dyslexic children and said mirror-image indicia being the mirror-image of the form in which they are seen by non-dyslexic children, whereby said blocks can be rotated to positions in which said mirror-image indicia appear in normal orientation in said mirror, allowing the use of said device to compare the mirror-image indicia carried by said blocks with their mirror-images (that is, their normal appearance) in said mirror by simply turning the blocks so that the mirror-image indicia reflect in the mirror; and (f) totally backwards alphabetic indicia carried by said at least some of said blocks on at least one face of each of said at least some of said blocks, said totally backwards indicia and said mirror-image indicia on each of said at least some of said blocks being related so that, when the totally backwards indicium is directly visible, the corresponding mirror-image indicium is reflected in said mirror in its normal orientation, allowing the user of the device to compare directly the totally backwards indicia carried by said at least some of said blocks with their normal appearance in said mirror, since both are simultaneously visible.
Claim 3
Dependent Claim 17 words
An educational device as recited in claim 1 wherein said blocks are rotatably mounted on said shaft.
Claim 4
Dependent Claim 18 words
An educational device as recited in claim 1 wherein said mirror-image indicia are releasably mounted on said blocks.
Claim 5
Dependent Claim 61 words
An educational device as recited in claim 1 and further comprising: (a) two bearing blocks, one mounted at each end of said base, said bearing blocks having open-topped slots therein sized to journal said shaft, and (b) a peg mounted in and projecting from each end of said shaft outside said bearing blocks, thereby limiting the axial movement of said shaft.
Claim 6
Dependent Claim 35 words
An educational device as recited in claim 4 wherein said bearing blocks are releasably mounted on said base, said pegs are releasably mounted in said shaft, and said blocks are releasably mounted on said shaft.
Claim 7
Dependent Claim 14 words
An educational device as recited in claim 1 wherein said indicia are raised surfaces.
Claim 8
Dependent Claim 14 words
An educational device as recited in claim 6 wherein said indicia are roughened surfaces.
