Title (EN) RETRACTABLE WRITING INSTRUMENT
(FR) INSTRUMENT D'ECRITURE RETRACTABLE
Abstract:
(EN) A writing utensil configurable between retracted and extended configurations is provided. The writing utensil includes a body having an interior volume and an aperture. A reciprocally movable nib assembly is located in the body and includes a nib that, when in the extended configuration, traverses the aperture. To prevent the nib from drying when in the retracted configuration, a sealing element seals the aperture. In an embodiment, the sealing element is a resilient valve element that can be opened by a sleeve slidably engaging the nib assembly. After the sleeve opens the valve, the sleeve slides with respect to the nib assembly to expose the nib. In another embodiment, the sealing element can be a sliding door that is attached to the nib assembly and overlays the aperture. When the nib assembly is moved to the extended configuration, the sliding door slides in a manner that opens the aperture.
(FR) L'invention concerne un instrument d'écriture rétractable pouvant passer de la configuration rétractée à la configuration déployée, qui comprend un corps à volume intérieur et ouverture. Un ensemble pointe à mouvement de va et vient se trouve dans le corps. La pointe une fois déployée traverse l'ouverture. Une obturation ferme l'ouverture pour empêcher la pointe rétractée de sécher. Selon une variante, l'obturation est une soupape souple susceptible d'être ouverte par un manchon qui s'imbrique coulissant avec l'ensemble pointe. Une fois la soupape ouverte par le manchon, la pointe est exposée car le manchon coulisse par rapport à l'ensemble. Selon une autre variante, l'obturation peut être une porte coulissante fixée à l'ensemble et chevauchant l'ouverture. Lorsque l'ensemble se déplace vers la position déployée, la porte coulissante coulisse de façon à libérer l'ouverture.
