Abstract

Ballpoint pen, of the type comprising a hollow handle, inside which are lodged several writing arrangements, each formed by a tubular ink tank, which supports at one end the writer tip, characterized the pen by the fact that the handle consists basically of two pieces joined together under pressure, integrating a rectangular section tube, one of the pieces of plastic material, which ends in a conical section and a through hole at its tip, which can access the outside any of the three writer dispositions housed in the handle, which are guided in its deposit by two holes drilled in a core introduced under pressure in the other basic part of the handle, which is metallic, thus dividing the internal space of the handle, integrating an upper compartment in which each writing arrangement has a spring wound on the end of its deposit, which is supported, in the mouth, supe of its bore, each tank being fixed with a spring by an angled piece, which on the one hand forms a pivot that is snapped into the mouth of the tank, and on the other side peeks out of the handle, on a button which is housed in a longitudinal slit formed in the wall of the metal part of the handle, which slit is curved at its lower end, so that the tension of each spring tends to keep the writing arrangement away from the lower mouth of the handle,. What is overcome: when the user slides the button in the slit. Until it is lodged in the curvature, where it is retained, with which the precise stroke in the writer's disposition will have been made so that it protrudes out of the handle, and recovering the occluded assumption by simply moving the button slightly, so that it is lifted from its seat. In, the curvature of the slit, again act the spring in the straight section of this one, doing it to go back. (Machine-translation by Google Translate, not legally binding)
