Abstract
Abstract This application discloses toy building blocks of similar shape but constructed to different modules. They are buildable together and, to this end, the inner protrusions of the smaller blocks coact with the outer projections of the larger blocks differently from the coaction within the module which is disclosed in U.S. Pat. No. 3,005,282.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
232 words
A toy building set of the type comprising downwardly open, rectangular, box-shaped building elements, each of which on the outer surface opposite the open side is provided with an even number, not less than four, of primary coupling studs serving to couple the element to a corresponding element by engagement between the sidewalls of the latter element said primary coupling studs being arranged with their axes in the corner of squares, said toy building set comprising at least two types of elements, smaller-type elements and larger-type elements, the smaller-type elements having a given basic module with respect to external dimensions and positioning of coupling studs, having a secondary stud arranged within the hollow space of the element centrally in relation to each square formed by the axes of the primary studs and so dimensioned as to engage four primary studs of another element of the same basic module, the larger-type elements having a module which is an integral multiple of the said basic module, its primary coupling studs being tubular, the external diameter of the secondary studs of the smaller-type elements being equal to the internal diameter of said primary studs of the larger-type elements and to the space between adjacent primary studs on such larger-type elements whereby adjacent secondary studs of a smaller-type element are capable of being gripped alternately within and between adjacent primary coupling studs of a largertype element.

Claim 3
Dependent Claim
49 words
A toy building set according to claim 1, characterized in that the ratio of the outer radius ''''A'''' of the said tubular primary studs to the radius ''''a'''' of the primary studs of the base element and its wall thickness ''''b'''' is substantially as follows: A a+(a+b) (2- 2).
Claim 4
Dependent Claim
33 words

Claim 6
Dependent Claim
211 words
A toy building set of the type comprising downwardly open, box-shaped building elements, each of which on the outer surface opposite the open side is provided with primary coupling studs serving to couple the element to a corresponding element by engagement between the sidewalls of the latter element said primary coupling studs being arranged with their axes in the corner of squares, said toy building set comprising at least two elements, a smaller one of which is considered as a base element of a given basic module with respect to external dimensions and positioning of coupling studs, said base element having at least three secondary studs within the hollow space of the element so dimensioned as to engage centrally four primary studs of another element of the same basic module, a larger second element having a module which is an integral multiple of the said basic module, its primary coupling studs being tubular, the external diameter of the secondary studs of the base element being equal to the internal diameter of said primary stUds of the second element and to the space between adjacent primary studs on said secondary element, whereby adjacent secondary studs are capable of being gripped alternately within and between adjacent primary coupling studs of said larger element.
Claim 7

Claim 8
Dependent Claim
125 words
A building set comprising at least two box-shaped building elements, a smaller one and a large one which has a module which is an integral multiple of that of the small one, each having sidewalls, a top wall, the large one having at least two studs on the upper surface of said top walls and the small one having at least three projections on the under surface of its top wall, the studs of said larger block being hollow and having an inside diameter equal to that of the under surface projections of the smaller block and being so spaced that the shortest path between the external surface of adjacent studs is substantially equal to the outside diameter of the projections of the smaller block.
Claim 9
Dependent Claim
