For assembly into permanent form (i.e. nonseparable):
(under subclass 85) Device wherein the parts are permanently fixed by the child.
(1) Note. Many toys are purchased in unassembled form, to be assembled prior to their first use, and many patents address the ease with which a toy is assembled. The original patents in this subclass; however, disclose toys in which a primary purpose is that the child carry out the assembly into a permanent form. A typical example is the "cut-paste" toy.
