Adjustable configuration toy

This invention is for an adjustable configuration toy which can be adapted to form various configurations, such as the letters of the alphabet, numerals, truss and beam arrangements and the like. It consists of a plurality of module units which can be coupled together at their ends by male and female coupling elements.

BACKGROUND AND SUMMARY OF THE INVENTION 
This invention relates to toy devices for use by children or minors, and 
more particularly to an adjustable configuration toy formed of module 
units. 
In the past, it has always been difficult to teach the letters of the 
alphabet and to form numerals in the education of minors. 
It is an object of this invention, therefore, to provide an adjustable 
configuration toy which can be utilized to teach children how to readily 
and easily form letters of the alphabet or numerals for educational 
purposes and to keep them usefully occupied. 
Another object of this invention is to provide an educational toy structure 
formed of identical modules which can be used as an educational aid for 
children. 
Still even another object of this invention is to provide an educational 
toy which can be used by all types of children on a worldwide basis for 
teaching the formation of various types of configuration, such as the 
alphabet or numerals or various types of structures. 
Another object of this invention is to provide an economical toy that can 
be readily assembled for educational or amusement purposes and quickly 
disassembled for storage thereof.

DESCRIPTION OF THE PREFERRED EMBODIMENT 
Referring now to FIG. 1 of the drawing, there is shown an adjustable 
configuration toy 10 used for forming the letters of the alphabet, 
numerals, or other configurations. 
This toy 10 is formed of a plurality of identical modules or units, such as 
12, 13, 14, 15, 16, 17, 18, 19, 20, and 21, which are coupled together at 
their respective ends as will be described below. 
Each module or unit 12, 13, 14, 15, 16, 17, 18, 19, 20, and 21, is of 
substantially rectangular shape lengthwise and crosswise. 
Referring now to FIGS. 3 and 4, one end of a module, for example, module 
15, is formed with an aperture or recess 22 therein with a plurality of 
spaced detents 15 formed around the periphery of the aperture or recess 22 
and spaced outwardly therefrom. 
The end of module unit 16, on the other hand, which engages with the end 
just described for module 15, is provided with a male coupling pin 24 
having a locking lip 26 and a corresponding number of evenly spaced 
detents 30 likewise spaced from the male coupling pin 24 and when rotated 
fit and engage between the detents 28 of the end of module 15. 
Each module 12, 13, 14, 15, 16, 17, 18, 19, 20, and 21, is thus formed with 
a female coupling aperture or recess at one end with detents 28, and on 
the opposite face at the opposite end of each corresponding module 12, 13, 
14, 15, 16, 17, 18, 19, 20, and 21 with a male coupling pin 24 and a 
corresponding number of detents 30. 
Referring now to FIG. 5, there is shown the ends of the modules 15 and 16 
of FIGS. 3 and 4 assembled in an operative positioned so as to couple two 
modules 15 and 16 together to form various types of configurations of the 
letters of the alphabet, such as "A" or "Z" as shown in FIG. 2. 
Thus any number of modules 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, or more 
or less, can be used to form any of the letters of the alphabet, numerals, 
truss or beam arrangements, or any shape or configuration desired. 
If desired the coupling elements can be arranged on the same side of each 
module 12, 13, 14, 15, 16, 17, 18, 19, 20, and 21, for example a coupling 
male element can be located at an end of a module unit and a female 
coupling element at the opposite end and on the same side of the module 
unit. Any other arrangement can be used as required. 
As can be readily understood the aforegoing description of the preferred 
embodiment of the invention can be configured in different modes to 
provide for various arrangements of the modules. Such configuring in 
different modes that utilize the novel and unique concept of this 
invention are within the scope and intent of this invention.
