Travel multiplier mechanisms for writing instruments |
摘要 |
A writing instrument includes a travel multiplier mechanism that includes a cam member that pivots about a pivot axis in response to motion of a push button member. The cam member engages a sliding piston member in order to provide a travel multiplying effect such that a distance of travel of the sliding piston member exceeds a distance traveled by the push button member. The cam member may be configured to rotate about an axis that is located in a plane perpendicular to a primary axis of a barrel of the writing instrument.
