Abstract
The present invention comprises a writing instrument of rod-like conformation such as a pen or pencil, the instrument being adapted to pivot medially of its length about a pivot pin to alow the forwardmost writing portion of the instrument to be rotated through a 180 degree angle and received within a housing cavity formed in the rearmost handle portion of the instrument. In use, the present writing instrument can be utilized in the manner of a typical pen or pencil, that is, as a straight rod-like writing instrument, the present writing instrument being alternatively utilized by disposing the two portions at an angle to each other while in use.
Claims2
A compact, foldable writing instrument comprising, in combination:
- a first elongated body member having a generally frustum-shaped forward portion terminating at a free end, said free end having an aperture formed therein and running axially through said frustum, and a first body rear portion having a substantially rectangular cross section and extending from said frustum to and including a pivot axis;
- a writing means having a single ink containing portion connected to a single writing tip, said ink containing portion being received within said aperture and said writing tip extending through said aperture for contact with a writing surface;
- a second elongated body member having a pair of spaced substantially planar body side walls and a laterally extending connecting wall attached to said body side walls longitudinally along one peripheral edge of each body side wall for defining a cavity for receiving said first body member, said spaced side walls having aligned apertures formed therein, said aligned apertures being positioned in alignment with said pivot axis of said first body member;
- a pivot pin being received through said aligned apertures in said pivot axis thereby forming a pivotal engagement between said body members such that said first body member may be disposed in longitudinal alignment with said second body member or pivoted into a received position within said cavity formed by the walls of said second body member or disposed in any given angular orientation between the longitudinal alignment or received position;
- a longitudinally extending ridge member attached laterally of said frustum and extending away from said second body member when said first body member is in the received position;
- and
- an abutment formed on the pivoted end of the second body member to form a stop to prevent pivotal movement of the first body member beyond the longitudinally aligned position, said abutment being defined by a free end of said laterally extending wall and a recess formed in said laterally extending connecting wall proximate said abutment for receiving the pivotal end of said first body member and allowing free pivoting of that member until engagement with said abutment.
