Claim 1
Independent Claim
203 words
A constructional toy consisting of: a first, generally L-shaped block (L), provided with bores (L1, L2, . . . , L10) of a diameter (d) arranged according to the following coordinates: L1: X=0; Y=0 L2: X=2P; Y=0 L3: X=3P; Y=0 L4: X=21/2P; Z=0 L5: X=-1/2P; Z=0 L6: X=-1/2P; Z=2P L7: Y=P; Z=0 L8: Y=-P; Z=0 L9: Y=0; Z=P L10: Y=0; Z=2P wherein X-Y-Z are the axes of right-angles coordinates system at the intersection of the three planes of symmetry of the block, and P is a fixed length greater than the diameter (d) of the bores; a second, generally U-shaped block (U) provided with bores (U1, U2, . . . , U14) arranged according to the following coordinates. U1: X=0; Y=0 U2: X=2P; Y=0 U3: X=3P; Y=0 U4: X=-3P; Y=0 U5: X=-4P; Y=0 U6: X=11/2P; Z=0 U7: X=21/2P; Z=0 U8: X=21/2P; Z=P U9: X=-21/2P; Z=0 U10: X=-21/2P; Z=P U11: X=-31/2P; Z=0 U12: X=-31/2P; Z=P U13: X=P; Z=P U14: Y=-P; Z=P; - a set of pins (R) slidingly receivable within the bores; - a set of strips (S) having bores arranged equidistantly therealong; and - a set of assembling blocks (A) of a prismatic shape, provided with split bores extending in perpendicularly, crossing directions.

Dependent Claim
203 words
A constructional toy consisting of: a first, generally L-shaped block (L), provided with bores (L1, L2, . . . , L10) of a diameter (d) arranged according to the following coordinates: L1: X=0; Y=0 L2: X=2P; Y=0 L3: X=3P; Y=0 L4: X=21/2P; Z=0 L5: X=-1/2P; Z=0 L6: X=-1/2P; Z=2P L7: Y=P; Z=0 L8: Y=-P; Z=0 L9: Y=0; Z=P L10: Y=0; Z=2P wherein X-Y-Z are the axes of right-angles coordinates system at the intersection of the three planes of symmetry of the block, and P is a fixed length greater than the diameter (d) of the bores; a second, generally U-shaped block (U) provided with bores (U1, U2, . . . , U14) arranged according to the following coordinates. U1: X=0; Y=0 U2: X=2P; Y=0 U3: X=3P; Y=0 U4: X=-3P; Y=0 U5: X=-4P; Y=0 U6: X=11/2P; Z=0 U7: X=21/2P; Z=0 U8: X=21/2P; Z=P U9: X=-21/2P; Z=0 U10: X=-21/2P; Z=P U11: X=-31/2P; Z=0 U12: X=-31/2P; Z=P U13: X=P; Z=P U14: Y=-P; Z=P; - a set of pins (R) slidingly receivable within the bores; - a set of strips (S) having bores arranged equidistantly therealong; and - a set of assembling blocks (A) of a prismatic shape, provided with split bores extending in perpendicularly, crossing directions.
