Abstract:
A side knocking-type writing instrument comprising: a barrel having a longitudinal axis, a front end, and a rear end; a sliding member for supporting a writing component and being disposed in the barrel for undergoing forward and rearward sliding movement along the longitudinal axis of the barrel, the sliding member having a shoulder comprised of a generally L-shaped side wall having a first wall portion extending along the longitudinal axis and a second wall portion extending transversely to the longitudinal axis; a knocking member mounted for pivotal movement in a direction transverse to the longitudinal axis of the barrel about a fulcrum point disposed at a rear portion of the knocking member, the knocking member having a pressing portion disposed at a front portion thereof; and a linking pawl disposed between the knocking member and the sliding member for undergoing pivotal movement therebetween and axial movement along the longitudinal axis, the linking pawl having an outward end disposed in contact with the pressing portion of the knocking member and an inward end disposed in contact with the shoulder of the sliding member; wherein when the pressing portion of the knocking member is pressed, the knocking member undergoes movement in the transverse direction so that the linking pawl is moved axially while being pivoted and the sliding member is slid forwardly to thereby protrude the writing component from the front end of the barrel.
