Abstract

Toy blocks and sets of toy blocks containing Braille characters for teaching young, sight-impaired children. A typical wooden block is cubical, comprising a pair of opposite, spaced apart display sides having recessed surfaces. One recessed surface contains a raised Braille character, and the opposite side displays the corresponding alphabetic or numerical character or characters. The recessed sides have borders comprising a bottom tactile-sensing portion that includes a plurality of raised nubs adapted to be touched for orienting the characters properly. Smaller Braille characters are preferably disposed beneath each alphabetic character.

Claims

1. A toy block for teaching Braille, said block comprising:

a generally cubical body having a plurality of faces;

a first of said faces comprising a Braille character; and

,

a second of said faces comprising an alphabetic or numeric character of characters equivalent to said Braille character;

wherein said first and second faces comprise a recessed surface from which said characters upwardly project for tactile perception; and

wherein each recessed surface comprises a raised peripheral boarder.

2. The toy block of claim 1 further comprising a bottom capable of tactile sensing that enables the user of said block to properly orient said characters for tactile reading.

3. A toy block for teaching Braille to children, said block comprising:

a generally cubical body having six faces;

a first one of said faces comprising a recessed surface displaying a Braille character; and

,

a second one of said faces comprising a recessed surface displaying the alphabetic or numeric character of characters equivalent to said Braille character;

wherein said characters are raised from said recessed surface for tactile sensing; and

wherein each recessed surface comprises a raised peripheral boarder.

4. The toy block of claim 3 further comprising tactile stimulating means for enabling the user of said block to properly orient said characters for tactile sensing.

5. The toy block of claim 3 wherein said raised peripheral border comprises tactile stimulating means for enabling the user of said block to properly orient said characters for tactile sensing.

6. The toy block of claim 5 wherein four of the faces of said block not marked with characters are serially contiguous and form a tactile-discoverable boundary between said first and second faces.

7. A toy block set for teaching Braille to children, said block set comprising a plurality of individual blocks comprising:

a generally cubicle body having a plurality of faces;

a first face comprising a recessed surface displaying a raised Braille character;

a second face comprising a recessed surface displaying alphabetic or numeric character or characters corresponding to said Braille character, said second face disposed on said body opposite from said first face, and said second face displaying a raised Braille character physically smaller than said last mentioned Braille character but corresponding to it.

8. The toy block set of claim 7 wherein each of said recessed surfaces comprise a raised peripheral border and said raised peripheral border comprises a tactile stimulating portion for enabling the user of said block to properly orient said characters for tactile sensing.

9. The toy block set of claim 8 wherein a plurality of said faces of each block in said block set are not marked with characters, and they are serially contiguous and form a tactile discoverable boundary between the faces marked with characters.
