Somier para camillo-bed perfected (Machine-translation by Google Translate, not legally binding)

摘要

Base for armchair-bed, perfected, essentially characterized because it is divided into four sections, which allow a perfect folding. The first section or head is joined to the foot, properly speaking, by means of two hinged plates on semitubular rivets. A coil spring maintains the necessary pressure in the foot-plate connection.
