Abstract
Device for blocking the inclination of a drawing board, characterized in that it comprises a horizontal cylindrical tube externally attached to the legs of the drawing table, which tube is joined at its ends to two separate frustoconical bearings with their smaller diameter mouths facing each other, having arranged in its interior so many frustoconical half-axes that on its external face have an annular step coupled to the eye of respective brackets joined to corresponding profiles that support the board; said axle shafts are linked together by a brace that passes through them and that at one end bears a nut and retaining nut, while at the other end it has a cylindrical head that has one part running through the respective semi-axle and another part of greater diameter diametrically crossed by a bar of section in the form of eccentric and commanded, by a lever form of eccentric and commanded by a perpendicular lever of accionamiento; the ends of the bar protrude from the cylindrical head, being attached, with interposition of a washer, to the external base of the respective semiaxis and, when the flattened portion is in contact with said washer, the semiaxes have possibility of turning inside their bearings at object to be able to vary the inclination of the board while, when actuating the lever and turning the eccentric a traction applied to the tie is produced, which forces to wedge and compact the pairs of semiejes bearings, blocking, therefore, the inclination granted to the board.
