Cardboard stool that is sold as a sheet to be assembled by the customers by bending and folding it
BRISVI is made from just a sheet of cardboard or other similar material, which appropriately bended and folded reaches its definitive form. The stool is formed by ruled and developable surfaces; the body of the stool is formed by a developable surface called convoluted; the seat of the stool by a cylindrical, and thus developable, surface; the base of the stool is flat, with elliptic or circular shape; and the internal stiffeners of the stool are also flat surfaces.
BRISVI is easy to store and distribute (it takes up very little space in its form of a sheet), lightweight, easy to assemble, resistant and cheap (little material, low-priced and easily produced). It is useful in the events in which it is necessary to have a variable number of seating places as reserve.
The body and the seat of the stool are sorted out by curved, continuous surfaces. These surfaces must be developable, so than we can produce (and then, supply and sell) it from a unique surface.
The flat sheet of cardboard (or other material with similar characteristics) is produced by die-cutting and marking it. The pre-cutting, folding and bending lines are made with the same die.
The sheet of cardboard (or other material with similar characteristics) is pre-cutting in order that the shapes forming the future stool can be easily separated.
