Title (EN) MECHANICAL PENCIL
(FR) PORTE-MINE
Abstract:
(EN) A mechanical lead pencil having the capability of feeding different diameter leads. A first collet (21) is disposed in the pencil barrel (12) for feeding the lead (20) and a second collet (25) is located at the barrel open end for retaining the lead (20) during use of the pencil. An elastomeric disc (35) is provided between the two collets (21, 25), having a variable diameter opening (38) at the center thereof for frictionally engaging the lead (20) and preventing its release when the two collets (21, 25) are in the open position.
(FR) Porte-mine utilisable avec des mines ayant un diamètre différent. Dans le corps du porte-mine, une première pince de serrage (21) sert à fournir la mine (20) et une seconde pince de serrage (25) située au niveau de l'extrémité ouverte du corps sert à retenir la mine (20) lorsqu'on utilise le porte-mine. Une rondelle en élastomère (35) est placée entre les deux pinces de serrage (21, 25), celle-ci étant pourvue d'une ouverture à diamètre variable (38) située en son centre qui lui permet de retenir la mine (20) par frottement et qui empêche la mine de sortie lorsque les deux pinces de serrage (21, 25) sont en position ouverte.
