Abstract
Abstract A toy element comprising at least two cup-like parts, each of said parts having a lower portion and an upper portion, said lower portion being shorter than that upper portion, the lower portion and the upper portion of each cup-like part having such a cross-sectional surface that said lower portion may be fitted clampingly in the upper portion of each one of the cup-like parts of another toy element, the cup-like parts of the toy element being interconnected by at least one connecting part, all this in such a way that with a number of said toy elements different spatial structures and compositions may be made.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
120 words
A toy element comprising at least two cup-like parts, each of said parts having a lower portion extending upwards from the bottom and an upper portion, said lower portion having an outer cross-sectional surface which is substantially equal to the inner cross-sectional surface of the upper portion so that said lower portion clampingly fits in the upper portion of a cup-like part of another toy element, said upper portions having a height which is larger than the height of the lower portion, the portions of greater height of the cup-like parts of the toy element being interconnected by at least one connecting part forming a single piece with the upper portions of the two cup-like parts of said toy element.
Claim 2
Dependent Claim
120 words
A toy element comprising at least two cup-like parts, each of said parts having a lower portion extending upwards from the bottom and an upper portion, said lower portion having an outer cross-sectional surface which is substantially equal to the inner cross-sectional surface of the upper portion so that said lower portion clampingly fits in the upper portion of a cup-like part of another toy element, said upper portions having a height which is larger than the height of the lower portion, the portions of greater height of the cup-like parts of the toy element being interconnected by at least one connecting part forming a single piece with the upper portions of the two cup-like parts of said toy element.
Claim 3
Dependent Claim
19 words
A toy element according to claim 1, characterized in that the cup-like parts of said toy element are identical.
Claim 4
Dependent Claim
29 words
A toy element according to claim 1, characterized in that the cross-section of each of the cup-like parts of said toy element has the shape of an equilateral polygon.
Claim 5
Dependent Claim
25 words
A toy element according to claim 1, characterized in that the cross-section of each of the cup-like parts has the shape of an equilateral octagon.
Claim 6
Dependent Claim
24 words
A toy element according to claim 1, characterized in that the cross-section of each of the cup-like parts has the shape of a circle.
Claim 7
Dependent Claim
43 words
A toy element according to claim 1, characterized in that the inner wall of each cup-like part is provided with at least one projection such as a rib and a raised portion, said projection extending over at least part of said inner wall.
Claim 8
Dependent Claim
33 words
A toy element according to claim 1, characterized in that the inner wall of the sides of each of the cup-like parts is alternately provided with two ribs extending parallel to each other.
Claim 9
Dependent Claim
63 words
A toy element according to claim 1, characterized in that the cup-like parts have an equilateral polygonal cross-section, said connecting part comprising two parallel sheet-like connecting members, each connecting members connecting two sides of said cup-like parts at the angular points and having a width which is substantially equal to the width of the sides of the polygonal cross-section of the cup-like parts.
Claim 10
Dependent Claim
88 words
A toy element according to claim 1, characterized in that the cup-like parts have an equilateral polygonal cross-section, said connecting part comprising two parallel sheet-like connecting members, said connecting members connecting two sides of said cup-like parts at the angular points and having a width which is substantially equal to the width of the sides of the polygonal cross-section of the cup-like parts, the lower ends of the sheet-like connecting members being connected by a bottom which is likewise connected with the corresponding walls of the cup-like parts.
Claim 11
Dependent Claim
121 words
A toy element comprising at least two cup-like parts, each of said parts having a lower portion and an upper portion, said lower and upper portions having complementary external and internal cross-sectional shapes, respectively, for removable frictionally resisted telescoping engagement of said lower portion into the upper portion of an identical toy element, said upper portions each being of an interior height greater than the exterior height of each lower portion, said cup-like parts being disposed in side-by-side spaced apart relation, and connecting structure formed integrally with and extending between adjacent sides of said upper portions, said connecting structure establishing a spacing between adjacent sides of said lower portions greater than the sum of the wall thicknesses of said upper portions.
Claim 12
Dependent Claim
121 words
A toy element comprising at least two cup-like parts, each of said parts having a lower portion and an upper portion, said lower and upper portions having complementary external and internal cross-sectional shapes, respectively, for removable frictionally resisted telescoping engagement of said lower portion into the upper portion of an identical toy element, said upper portions each being of an interior height greater than the exterior height of each lower portion, said cup-like parts being disposed in side-by-side spaced apart relation, and connecting structure formed integrally with and extending between adjacent sides of said upper portions, said connecting structure establishing a spacing between adjacent sides of said lower portions greater than the sum of the wall thicknesses of said upper portions.
