Document Type and Number:
WIPO Patent Application WO/1986/004253
Kind Code:
A1
Abstract:
This invention has been developed by eliminating the drawbacks encountered in conventional toy blocks or teaching materials. Toy blocks according to the present invention consist of bodies having a square surface, a rectangular surface or a surface of some other shapes, on which a letter, a numeral or a symbol is shown. The blocks have on their side surfaces racks consisting of alternate projections and recesses of the same dimensions. Therefore, such blocks can be combined horizontally, vertically and at acute and obtuse angles at any portions of the racks in a variety of ways by the collective functions of the racks, so that the blocks can be used to teach the construction of a letter, how to arrange words, how to count numbers and how to use symbols. Also, these blocks can be combined to form an object with the letters on their surfaces arranged to show the name thereof, or a special model which must be formed by combining the blocks incliningly.
