Abstract:
1. A retractable adaptor for holding an off-the-shelf writing instrument having a writing tip, wherein the adaptor comprises: an adapter body having a distal end and a proximal end; a lumen within the adapter body to at least partially enclose the writing instrument; an opening at the distal end of the adapter body allowing a writing tip of the writing instrument to pass through; a holder disposed within the lumen of the adapter body to contact the writing instrument; a contact surface disposed on an inner side of the holder to make engaging contact with the writing instrument; a retractable mechanism to selectively move the holder within a defined longitudinal distance within the adapter body such that movement of the holder towards the distal end causes the writing tip to extend through the opening and be exposed from the adapter body for writing, and movement of the holder towards the proximal end causes the writing tip to retract through the opening and be hidden and protected within the adapter body; and wherein the off-the-shelf writing instrument is a pen having an ink filling holding ink, an outer tubular body having an outer diameter of at least 6 mm and encloses the ink filling.
