Abstract

Abstract A toy comprises a number of mutually connected bodies of wood, plastic, metal, cork or the like arranged in a row in which consecutive bodies are joined turnably in such manner that the friction between the surfaces of the bodies resting against each other counteracts the turning. In each body both such contact surfaces have different directions, that is that in each body both turning axes have different directions.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 170 words
A toy comprising a plurality of parts each said part having opposite inclined planar surfaces, each of said parts having a bore extending from one said surface thereof to the other, an elastic connecting band extending through the bores of the parts to hold the parts in assembled end-to-end relation to form an assembly having one said part at each end and the remaining said parts therebetween, with the surfaces of each said remaining part in contact with the surfaces of adjacent ones of said parts, and means securing the elastic connecting member at the ends thereof to the parts at the opposite ends of the assembly, said elastic connecting member being in tension and thereby exerting pressure on said parts and developing friction between the contacting surfaces, whereby the shape of the assembly is variable by mutually independently turning said parts and the shape resulting is maintained by the pressure and friction which is developed, each said part being a symmetrical body and the bore therein being substantially axial.
Claim 2
Dependent Claim 170 words
A toy comprising a plurality of parts each said part having opposite inclined planar surfaces, each of said parts having a bore extending from one said surface thereof to the other, an elastic connecting band extending through the bores of the parts to hold the parts in assembled end-to-end relation to form an assembly having one said part at each end and the remaining said parts therebetween, with the surfaces of each said remaining part in contact with the surfaces of adjacent ones of said parts, and means securing the elastic connecting member at the ends thereof to the parts at the opposite ends of the assembly, said elastic connecting member being in tension and thereby exerting pressure on said parts and developing friction between the contacting surfaces, whereby the shape of the assembly is variable by mutually independently turning said parts and the shape resulting is maintained by the pressure and friction which is developed, each said part being a symmetrical body and the bore therein being substantially axial.
Claim 3
Dependent Claim 19 words
A toy as claimed in claim 1, wherein each said part is cylindrical and said surfaces are end faces.
Claim 4
Dependent Claim 16 words
A toy as claimed in claim 2, wherein said bore is coaxial in the cylindrical part.
Claim 5
Dependent Claim 26 words
A toy as claimed in claim 3, wherein said end faces are inclined to said axis at equal and opposite angles and said parts are identical.
Claim 6
Dependent Claim 28 words
A toy as claimed in claim 3, wherein said elastic band has ends with knots secured in the bores in the parts at the ends of the assembly.
