Abstract (en)
[origin: WO2008040912A2] The invention relates to a fixed-nib writing instrument (6) having a shaft (1), to the front of which a protective sleeve (2) is movably fitted coaxially relative to the shaft (1), the movement of said sleeve taking place between a protective position in which it covers the writing nib and a retracted position in which it permits writing. The sleeve (2) comprises a wall portion (2A) having at least one helical guide path (20, 21) that engages with at least one stud (10, 11) connected to the shaft (1). Means of retention of the rotation of the sleeve (2) are provided to prevent the sleeve rotating at less than a certain threshold effort in the two positions of protection and retraction, and comprise at least one lengthwise rib (26, 27) suitable for engaging elastically in a first groove (16, 17) and in a second groove (16', 17') for the protective and retracted positions, respectively.
