MECHANICAL PENCIL COMPRISING A RETRACTABLE LEAD GUIDE

摘要

The invention relates to a mechanical pencil comprising a tip (4) into which a lead guide (5) can be retracted. The lead guide comprises a conduit (6) through which a lead (9) can pass and be guided in translation. A deformable lead brake (13) is equipped with (i) at least one lead/lead brake friction area which limits the movement of the lead (9) in the lead guide (5) and (ii) at least one tip/lead brake friction area which limits the movement of the lead guide (5) in the tip (4). Each lead/lead brake friction area is offset angularly around an axis X in relation to each tip/lead brake friction area. ® KIPO & WIPO 2007
