Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
138 words
An assembly toy comprising: a plurality of devices for removably connecting a plurality of cylindrical objects, each device including means for coupling to a cylindrical object, each cylindrical object having a longitudinal axis, and means for removably coupling each device to another such device and wherein said means for removably coupling comprises a first engagement element and second and third engagement elements, said second engagement element being arranged for rotatable locking engagement with a first engagement element on another such device, said rotatable locking being with respect to a rotation axis which is perpendicular to the longitudinal axes of adjacent cylindrical objects, and said third engagement element being arranged for non-rotatable locking engagement with a first engagement element on another such device in any one of a plurality of predetermined angular relationships with respect to adjacent longitudinal axes.

Claim 3
Dependent Claim
18 words
An assembly toy according to claim 1 and wherein said means for removably coupling comprises snap fitting means.
Claim 4
Dependent Claim
25 words
An assembly toy according to claim 1 and wherein said means for removably coupling provides orientation of the cylindrical objects in predetermined relative axial orientations.
Claim 5
Dependent Claim
25 words
An assembly toy according to claim 1 and wherein said means for removably coupling provides orientation of the cylindrical objects in selectable relative axial orientations.
Claim 6
Dependent Claim
20 words
An assembly toy according to claim 1 and comprising means for providing axial friction fit engagement with the cylindrical elements.
Claim 7
Dependent Claim
19 words
An assembly toy according to claim 1 and comprising means for providing snap fit engagement with the cylindrical elements.
Claim 8
Dependent Claim
52 words
An assembly toy according to claim 1 and wherein said first engagement element comprises a universal socket, said second engagement element comprises a circular protrusion engageable with said universal socket in a free-azimuth coupling and said third engagement element comprises a non-circular protrusion engageable with said universal socket in a fixed-azimuth coupling.
