A writing instrument (10) includes a travel multiplier mechanism (12) that includes a cam member (16) that pivots about a pivot axis in response to motion of a push button member (14). The cam member engages a sliding piston member (22) in order to provide a travel multiplying effect such that a distance of travel of the sliding piston member exceeds a distance traveled by the push button member. The cam member (16) may be configured to rotate about an axis that is located in a plane perpendicular to a primary axis of a barrel of the writing instrument.
L'invention concerne un instrument d'écriture comprenant un mécanisme multiplicateur de déplacement présentant un élément à came pivotant autour d'un axe de pivot en réponse au mouvement d'un élément de bouton à pousser. L'élément à came vient en prise avec un élément de piston coulissant afin de conférer un effet multiplicateur de déplacement, de manière que la distance de déplacement de l'élément de piston coulissant dépasse une distance parcoure par l'élément de bouton à pousser. L'élément à came peut être conçu de manière à tourner autour d'un axe situé dans un plan perpendiculaire à un axe principal du corps de l'instrument d'écriture.
