Abstract
Abstract A craft is provided which employs one or more rigid frames which are so constructed as to facilitate the winding of one or more filaments or wires therearound to form an envelope or envelopes of the filaments to permit the construction of geometric configurations representing abstract art, figures, animals and other forms. In one form, the frames are produced of molded plastic and contain scalloped edges which are shaped with indentations in which indentations a filament may be nested as it is wrapped around the frame so as to predeterminately dispose the filament in selected spaced-apart locations on the frame. In another form, the frames are molded with a plurality of equispaced protrusions around which filament material may be wrapped and retained thereby to form the envelope of filamentary wrappings. The frames are also constructed so that they may be easily assembled and retained together to form a three-dimensional skeletal support for the filamentary material.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
229 words
An assembly toy and craft comprising in combination: a first member shaped in the configuration of a closed frame and having integrally formed therein of the material thereof a plurality of irregular formations which are configured to receive and retain a filamentary material, a second member of sheet-like configuration and having the peripheral border portions thereof shaped with a plurality of irregular formations for retaining a filamentary material, respective inside edge portions of said first frame member and outside edge portions of said second frame member being configured to permit the frictional assembly and retention of said second frame member within and across the inside of said first frame member whereby most of the border portions of said second frame member extend laterally outwardly of said first frame member and wherein said irregularly shaped formations of said first and second frame members are exposed to and may serve as guides for a filamentary material such as a thread, metal wire or flexible plastic filament which is wrapped around the assembly a number of times and may be retained by the side surfaces of said irregular formations as a plurality of turns of a winding of said filamentary material around the assembly of said first and second members wherein each of said turns is substantially fixed in location on the assembly with respect to the other turns of filamentary material.
Claim 2
Dependent Claim
229 words
An assembly toy and craft comprising in combination: a first member shaped in the configuration of a closed frame and having integrally formed therein of the material thereof a plurality of irregular formations which are configured to receive and retain a filamentary material, a second member of sheet-like configuration and having the peripheral border portions thereof shaped with a plurality of irregular formations for retaining a filamentary material, respective inside edge portions of said first frame member and outside edge portions of said second frame member being configured to permit the frictional assembly and retention of said second frame member within and across the inside of said first frame member whereby most of the border portions of said second frame member extend laterally outwardly of said first frame member and wherein said irregularly shaped formations of said first and second frame members are exposed to and may serve as guides for a filamentary material such as a thread, metal wire or flexible plastic filament which is wrapped around the assembly a number of times and may be retained by the side surfaces of said irregular formations as a plurality of turns of a winding of said filamentary material around the assembly of said first and second members wherein each of said turns is substantially fixed in location on the assembly with respect to the other turns of filamentary material.
Claim 3
Dependent Claim
53 words
A toy and craft in accordance with claim 1 wherein each of said irregular formations formed in said first and second members is of substantially similar configuration as a plurality of the others permitting the filamentary material wrapped around the assembly to be formed into a plurality of turns of substantially equal spacing.
Claim 4
Dependent Claim
33 words
A toy and craft assembly in accordance with claim 1 wherein said irregular formations in said first and second members comprise irregular formations along the outer edges of said first and second members.
Claim 5
Dependent Claim
60 words
A toy and craft in accordance with claim 3 wherein said irregular formations along the outer edges of said first and second members comprise scallopping therein defined by respective narrow gullies between adjacent scallop formations with each gully adapted to receive and retain at least one turn of said filamentary material against sliding movement along the edge of the member.
Claim 6
Dependent Claim
23 words
An assembly toy and craft in accordance with claim 1 wherein said second member is also configured in the shape of a frame.
Claim 7
Dependent Claim
59 words
An assembly toy and craft in accordance with claim 1 wherein said first member contains respective slot-like indentations formed in its inside surface diametrically across the frame and said second member is configured with portions thereof adapted to frictionally assemble with and be retained by the surfaces of said slot-like indentations in said inside portions of said first member.
Claim 8
Dependent Claim
75 words
An assembly toy and craft in accordance with claim 1 wherein said first and second members are configured to represent, when assembled together, a character such as an animal, fish or other known character shape and the wrapping of a filamentary material a number of times around the assembly of said first and second members is operable to form an envelope of said filamentary material which somewhat represents the three-dimensional surface configuration of said character.
