Abstract
Improvements in the construction of drawing boards, characterized, essentially, because the system of blockade of inclination of the board itself, consists essentially of a tube traversed longitudinally by two rigid rods, at whose ends is fixed and if necessary susceptible to protrude through the tube cap, running between both rods two sectors, fixed to the board orthogonal to it and aligned according to the ideal geometric axis, the locking device constituting a roller eccentrically stamped on the ends of the rods, roller comprising a semi-cylindrical side recess operative to locate a cylinder that affects the sector, actuating the position of the roller according to a conventional handle, the cylinder constituting the lever mechanism that determines the handle and roller assembly whose mechanism determines the traction and axial sliding of the rods inside the tube that contains them and the retention of the opposite sector by a fork arrangement.
