Abstract
A writing instrument is disclosed having a display flag attached to an internal pen holder such that the flag may be displayed either by pulling it laterally through any elongated opening in an external pen holder, or by axially extending the internal pen holder from the external pen holder. A positioning block attached to the internal pen holder limits the relatively axial sliding movement between the internal and external pen holders to prevent the user from completely pulling the internal pen holder from the external pen holder. The writing instrument may also be placed in a base such that the flag may be displayed while the base rests on a desk, table, or the like.
Claims5
A writing instrument having means to display a flag or the like comprising:
- (a) an external pen holder having generally hollow cylindrical shape and defining an elongated opening extending along less than the length of the external pen holder, through a wall of the external pen holder, the elongated opening having a bottom;
- (b) an internal pen holder axially slidably and rotatably received in the external pen holder having a generally hollow cylindrical shape, the internal pen holder defining a slot extending completely along its length such that the internal pen holder has a generally "C" shaped cross-sectional configuration;
- (c) an obstruction hole defined by the external pen holder near an upper end thereof;
- (d) a positioning block fixedly attached to a lower portion of the internal pen holder, the positioning block having a projecting edge extending into the elongated opening in the external pen holder and a flexible tenon extending from a side thereof such that relative axial sliding movement between the internal and external pen holders is limited in a first direction by contact between the projecting edge of the positioning block and the bottom of the elongated opening and in an opposite direction by engagement of the obstruction hole and the flexible tenon;
- and,
- (e) means attached to the internal pen holder to deform its cross-sectional shape so as to close the slot such that an edge of the flag or the like is clamped onto the internal pen holder.
