Olivetti Praxis 48 vintage typewriter para reparação.
Ettore Sottsass, like many Italian designers, was originally trained as an architect before going on to a long career in multi-disciplinary design. That background may help explain the architectural look of the Praxis 48 typewriter that Sottsass designed for Olivetti. Unlike the personal, portable, and manual Valentine for which he is more famous, the Praxis 48 is large, heavy, electrically-powered, and intended for day-in, day-out office use. But despite its size, weight and angularity, the Praxis 48 is a masterful example of creating visual tension and contrast.

In describing the Praxis 48 for its winning of the Compasso d'Oro Italian design prize in 1970, the judges praised "it clearly shows its structure; the spaces between the different parts are clean and emphasized. Thus the machine is truly 'composed', it looks like an assembly of various elements. Elements reduced to an extreme simplicity of profiles and planes." (1)

Let's begin from the side. It's this side view that first struck me when I saw a picture of the Praxis 48 years ago. A wonderfully proportioned block presents up the keyboard cantilevered out the front in a dramatic gesture. And it's not cantilevered just by a little bit. The floating keyboard is a full third of the depth of the machine. There's a tension between the suspended keyboard (onto which you are pounding with your fingers) and the visually and actually heavy main block. Technical innovation by Olivetti's engineers led to a more compact keyboard mechanism. Another innovation allowed the carriage to be set lower into the main box for a sleeker look.
