Abstract

Improved retractable ball pen, of the type in which the exit or concealment of the inscribing tip is achieved by the displacement of a push button associated with the ink load and the expansion of an opposing spring linked to said load, characterized in that said positions are reached by means of axial and angular displacements of a moving part having the peripheral area of one of its ends configured with radial equally spaced radial fins, so that its angular displacements are initially caused when it is pushed axially downwards by a pushbutton bottomed in crown with pointed teeth, which affect the bevelled surfaces, and complement when said piece backs down due to the expansion of the spring, thus affecting projections provided inside the constituent part of the body of the ballpoint pen in the piece constitutive of the pen body in which it slipped a, the spaces between said projections being alternately provided with stops, so that the ink load of the axial displacements of said piece is integral, the inscription tip will be alternately protruding to the outside or retracted inside the pen, according to which the fins radials of said moving part are introduced in spaces between gifted or non-stop projections.
