<p>The invention relates to means for designing and modelling ready-made spectacles, including the different modifications and standard sizes thereof. The inventive unit-construction assembly comprises a set of three-dimensional elements which are embodied in such a way that they are fixable to each other by means of the protrusions (1) formed on one parts of elements and mortises (2) which are produced on the other part of elements and fit the shape of said protrusions. Said set of three-dimensional elements is embodied in the form of an aggregate of the following spectacle parts: right (3) and left (4) eye glasses interconnected by a nose bridge (5) provided with a nose rest (6), right (8) and left (11) ear arms provided with right (9) and left (12) endpieces and right (7) and left (10) brackets for connecting eye glasses to the ear arms, wherein the number of each three-dimensional elements ranges from one to one hundred. The three-dimensional elements of the same denomination are embodied in such away that they have different shapes and sizes. The unit-construction assembly is provided with a sectional container and makes it possible to rapidly and easily interchange the spectacle elements.</p> |
