Title: WRITING INSTRUMENT WITH RESETTING OPERATING UNIT
Abstract:
The invention relates to a writing instrument (2) which has a housing (4) for receiving a writing material (6), an operating end (10), and a writing end (12). The housing (4) is equipped with an adjusting mechanism which comprises a guide sleeve (14) and a spring-loaded cam pin (16) that is concentrically arranged in the guide sleeve and can be brought into engagement with the end of the writing material (6). The cam pin (16) can be moved into at least two latching positions which are offset along the longitudinal axis (8). The writing instrument (2) further has a control assembly (18) with a resetting device (20), a freewheel mechanism (22) which can be coupled to an operating unit (24) arranged at the operating end (10), and a cam sleeve (26) which can be coupled to the freewheel mechanism (22). The resetting device (20) exerts a returning force on the operating unit (24). The freewheel mechanism (22) is designed as a first rotatably mounted body, at least part of which becomes operatively connected to a second body (32) mounted for concentric rotation with respect to the first body. One of the first (22) and the second (32) rotatably mounted bodies is freely rotatable about its longitudinal axis (8) through a first angular range, and when outside the angular range it transmits rotation from the operating unit (24) to the cam sleeve (26).
