Abstract
A handwriting instrument consists of a top part (1) and a connected intermediate part (2), on the end of which a tip (3) is fastened. To make it possible to insert the intermediate part (2) into the top part (1) rapidly and securely during the assembly of the handwriting instrument, there are two detent elements (5) and two lead-in bevels (8) on the top part (1), which guide two flexible studs (4) into the detent elements (5), where the studs (4) are locked. A sleeve (11) fastened to the intermediate part (2) by means of a bayonet connection (13, 21; 12, 14, 20) covers the studs (4) and the detent elements (5). For easy handling of the writing instrument, there is a grip (18) made of non-slip but soft rubber on the intermediate part (2).
Claims7
Handwriting instrument with a refill consisting of a top part (1), an intermediate part (2) and a tip (3) that can be fastened to the lower end of the intermediate part (2), characterized by the fact that at least one flexible stud (4) located on the intermediate part (2) is guided in a diagonal detent element (5) of the top part (1) so that the intermediate part (2) can be displaced in the longitudinal direction relative to the top part (1) by rotating the intermediate part (2) relative to the top part (1), whereby depending on the direction of rotation, the tip (6) of the refill (7) is exposed or covered, and that on the lower end of the top part (1) there is an lead-in bevel (8) to guide the studs (4) during insertion of the intermediate part (2) into the top part (1).
