A-R
A/R - Before the automatic closing mechanism was invented, it was enough to tilt the axis of rotation of a door to make it shut by itself. A solution so simple and fascinating. The design process of this patent has led us to find a solution that possessed a lightweight nature: the addition of materials was reduced to a minimum, the product took on the characteristics of a folded sheet of paper and, consequently, the shutter`s structure and functioning was brought to their essence.
