Abstract[English]
The invention discloses a portable stationery device designed to be worn on the wrist, integrating a pencil sharpener with a retractable eraser. The core mechanism involves an eraser connected via a cord to a spool, which is driven by a spiral spring. Pulling the eraser causes the cord to extend and the spring to compress. A locking mechanism secures the eraser in its extended position. Releasing the lock permits the stored energy in the spring to retract the eraser by winding the cord back onto the spool. The pencil sharpener is fixed adjacent to the eraser compartment, forming a unified, wearable unit attached to a wrist strap. This innovative design significantly reduces the risk of losing stationery items and minimizes choking hazards, particularly for children, while greatly enhancing user convenience and accessibility during writing and drawing tasks.[French]
L'invention concerne un dispositif de papeterie portable destiné à être porté au poignet, intégrant un taille-crayon à gomme escamotable. Le mécanisme central comprend une gomme reliée par l'intermédiaire d'un cordon à une bobine, qui est entraînée par un ressort en spirale. La traction de la gomme amène le cordon à s'étendre et le ressort à se comprimer. Un mécanisme de verrouillage fixe la gomme dans sa position étendue. La libération du verrou permet à l'énergie stockée dans le ressort de rétracter la gomme en enroulant le cordon sur la bobine. Le taille-crayon est fixé de manière adjacente au compartiment de gomme, formant une unité unifiée pouvant être portée fixée à un bracelet. Cette conception innovante réduit significativement le risque de perte d'articles de papeterie et réduit au minimum les risques d'étouffement, en particulier pour les enfants, tout en améliorant considérablement la commodité et l'accessibilité de l'utilisateur lors de tâches d'écriture et de dessin.
