Abstract

A novel educational toy is provided which comprises, in combination, an elongated support rod and a plurality of separated magnetic members slideably received on the rod. Each member has a pair of opposed faces, the faces having an opposite polarity to each other, and the members are arranged on the rod so members of separate groups are magnetically attracted to one another, while each group repels adjacent groups, so that groups are effectively spaced along the rod. Each magnetic member bears identifying indicia, the members of each group also collectively providing separate distinct group indicia. The member indicia may be symbols, numbers, letters, or the like. Alternatively, they may be configurations for the members which resemble solid objects.

A handle may be provided for moving the entire toy. The members can be easily aligned with each other by means of for example, matching detents on adjoining faces, and/or tabs to facilitate handling thereof. The rod may be in a hoop configuration, or in a square or a straight length, and a plurality of rods can be employed to form a ladder or abacus configuration or the like. The toy is simple, inexpensive, and durable, and is capable of teaching physical dexterity, letter combinations, etc., to form words, simple mathematical computations and other relationships, while amusing the child user.

Claims

1. A novel educational toy comprising in combination:

a. an elongated support rod;

b. a plurality of separate magnetic members slideably received on said rod, each said member having a pair of opposite sides of opposite magnetic polarity, said members being mutually magnetically attracted into separate groups on said rod, said groups being mutually magnetically repelled from each other so as to be spaced along said rod;

c. wherein some of said members bear identifying indicia;

d. wherein members of each of said groups collectively provide a separate distinctive group indicium; and

e. wherein said indicia are letters of the alphabet.

2. The educational toy of claim 1 wherein each group has related letters which form words.

3. The educational toy of claim 1 wherein the groups collectively spell out a sentence.

4. A novel educational toy comprising in combination:

a. an elongated support rod;

b. a plurality of separate magnetic members slideably received on said rod, each said member having a pair of opposite sides of opposite magnetic polarity, said members being mutually magnetically attracted into separate groups on said rod, said groups being mutually magnetically repelled from each other so as to be spaced along said rod;

c. wherein some of said members bear identifying indicia;

d. wherein members of each of said groups collectively provide a separate distinctive group indicium; and

e. wherein all said members of each group have the same configuration and wherein the members of each said group differ in configuration from members of said other groups.

5. A novel educational toy comprising in combination:

a. an elongated support rod;

b. a plurality of separate magnetic members slideably received on said rod, each said member having a pair of opposite sides of opposite magnetic polarity, said members being mutually magnetically attracted into separate groups on said rod, said groups being mutually magnetically repelled from each other so as to be spaced along said rod;

c. wherein some of said members bear identifying indicia;

d. wherein members of each of said groups collectively provide a separate distinctive group indicium; and

e. wherein a plurality of said rods are disposed in a ladder configuration, wherein said group indicia are numbers and wherein the indicia of the members of each said group bear mathematical relationship to the indicium of that group.
