Abstract

A bolt-action pen body is adapted as a universal receiver of an ink cartridge refill. The bolt action pen includes a hollow cylindrical pen body. A tip is removably coupled with an outer barrel at the distal end of the pen body. A refill cartridge is selectively extensible and retractable from the tip by a lever action movement of a bolt and a bolt carrier within a slot defined through a sidewall of the pen body. The bolt action pen provides for universal adjustment to various shapes of refill cartridges. An inner barrel is coupled with the pen body and is configured to adjust the pen body to a longitudinal length of the refill cartridge. A collet carried within the tip is configured for compressive adjustment to a diameter of writing end of the refill cartridge.

A bolt action pen for universal reception of a refill cartridge, comprising:

a pen body having a proximal end, a distal end, an inner surface, an outer surface, an interior cavity, and a first thread on the inner surface extending inwardly from the distal end;
a bolt and a bolt carrier, configured to selectively advance and retract the refill cartridge between a writing position and a stowed position, via a slot extending through the proximal end of the pen body;
an inner barrel dimensioned to adjustably receive a reservoir end of the refill cartridge, the inner barrel having an adjustment thread at a proximal end received with the first thread of the pen body, and a threaded shoulder region at a distal end;
an outer barrel having an inner bore and a second thread defined in a distal end of the inner bore, the second thread configured to couple with a proximal end of the threaded shoulder region;
a tip carried on a distal end of the threaded shoulder region;
and a collet carried within the tip, the collet configured for compressive adjustment to a writing end of the refill cartridge.
