  • the shaped coupling is realized for example by means of a square shape, or a four-pointed star, or through holes and protrusions positioned in correspondence with the cardinal points.
  • Such constructive choice simplifies the production of the hinge: by making an insert couplable to the body with alternative rotations (0, 90, 180, 270 degrees), it is possible to obtain different coupling configurations of the hinge with the same two elements.
