Element for toy or model system - is assembled with similar elements to form smooth flat or three dimensional structure.

摘要

The flat smooth surface are either parallel or at right angles to one another and are symmetrical with the diagonal axis (3). Each two interlocking elements have shared surfaces which are parallel to each other or stand vertically on one another. With the exception of a cube, all the cavities in the paired elements are always completely filled by protuberances for form a connection which is form-locking and frictionally resistant. The broad protuberances are divided symmetrically by slits (2). USE/ADVANTAGE - The element has a simple, attractive and clear shape which when assembled forms a stable structure made of simple economical and natural materials which can be sawn or milled.
