Abstract
A writing instrument may include a barrel having a longitudinal axis, a cartridge, a writing tip, a self-retracting system for sliding the cartridge inside the barrel between a first position wherein the writing tip extends outside the barrel and a second position wherein the writing tip is retracted, the system comprising a button configured to move the cartridge between the first and the second position, and a sealing member configured to be actuated between a closed position closing a writing passage of the writing instrument, wherein the self-retracting system further comprises a linkage that connects the button and the cartridge, the linkage being configured to convert an actuation of the button into a linear motion of the cartridge along the longitudinal axis.
Claims18
A writing instrument comprising:
- a barrel having a longitudinal axis,
- a cartridge,
- a writing tip provided at one end of the cartridge,
- a self-retracting system configured to slide the cartridge axially inside the barrel between a first extended forward position wherein the writing tip extends outside the barrel and a second retracted rearward position wherein the writing tip is retracted inside the barrel from the first extended forward position along an axial rearward direction, the self-retracting system comprising:
- a button configured to, when actuated, move the cartridge into the first extended forward position, and when not actuated, move the cartridge into the second retracted rearward position, and
- wherein the self-retracting system further comprises a linkage that connects the button and the cartridge, the linkage being configured to convert an actuation of the button into a linear motion of the cartridge along the longitudinal axis, and wherein the linkage comprises a first sliding end configured to slide against an inclined surface of the cartridge, the linkage and the cartridge being configured so that upon actuation of the button, the first sliding end exerts pressure on the inclined surface so as to move the cartridge frontward.
