Molecular model for chemistry
First Claim
1. A molecular model building member comprising a main portion with two arms connected to and emanating outwardly from said main portion, said member being formed of relatively flexible material permitting said arms to be bendable relative to said main portion, one of said arms being comprised of a first section connected to said main portion and a second section connected to said first section so that said first section is interposed between said main portion and said second section, said second section of said one of said arms having an annular rib around the periphery thereof and having a smaller cross-section than said first section so as to form a first annular shoulder at their intersection, the other of said arms having a bore therein to receive the second section of said one of said arms of another of said molecular model building members and to frictionally engage the annular rib provided thereon.

Abstract
A molecular model building set for the formation of models of molecules and compounds primarily in the field of organic chemistry is disclosed. The set includes dimensionally accurate model building members (10, 60) that are rotatable about their axes, and can be interconnected and/or interlocked to form specific molecular models. Model building members depicting a double molecular bond (80) and a triple molecular bond (90) are also provided and can be interconnected and/or interlocked with the model building members (10, 60). All of the aforementioned model building members (10, 60, 80 and 90) are formed from a polypropylene copolymer material resulting in the members being inherently flexible while retaining sufficient rigidity to depict strain in molecular bonding. Because of this flexibility, the rotatability of the members, and the manner in which the members can be interconnected and/or interlocked, models of all known molecules and compounds in the field of organic chemistry can be formed.
