Abstract:
The “Pivot Pencil” is a writing instrument: carpenters pencil, mechanical pencil, pen, marking pen, etc; A Pivot Swivel Joint inserted into the center of the Wooden Outer Casing that “allows the tool to pivot in various angles”, which allows the pencil access in tight spots and around corners. If you can&#39;t reach the surface you wish to mark, you might as well guess. But the “Pivot Pencil” can take away all the guesswork. The unique pivoting design is all the accuracy you need.

Referring to  FIGS. 4 ,  5 ,  5 A, the female end  15 , of the swivel joint assembly  11 , has a shaft 0.187 of an inch in diameter on one end and a spherical ball shape 0.250 of an inch in diameter on the opposite end. The female end  15 , measures 0.688 of an inch in total length. (2) tongs are cut out on the center line of the spherical ball shaped end parallel to the length of the shaft to form a fork like shape. Each tong is 0.083 of an inch in thickness with a 0.083 of an inch space between the tongs, and a depth of 0.250 of an inch. The male end  14 , of the swivel joint assembly  11 , has a shaft 0.187 of an inch in diameter on one end, and a spherical ball shape 0.250 of an inch in diameter on the opposite end, and measures 1.250 inches in total length. (1) tong is cut out on the center line of the spherical ball shaped end parallel to the length of the shaft. The tong is 0.08 of an inch in thickness and 0.250 of an inch in depth. A hole is drilled through the 0.250 inch diameter spherical part of the male  14 , and female  15  of the swivel joint assembly  11 , perpendicular to the longitude of the shaft and center line of the 0.250 diameter sphere, and then tapped. A screw  16  is mounted in the spherical center point of the swivel joint assembly  11 , swivel ably connecting the female  15 , and male  14 . Referring to  FIGS. 1 and 2 , The elongated shaft of the female end  15  and the male end  14  of the swivel joint  11  are inserted into bores  17 , and  18 , of segments  2 A, and  2 B respectively, and positioned geometrically to where the pivot axis of the swivel joint assembly  11 , is perpendicular to the longitude, and parallel to the width of segments  2 A,  2 B, then permanently secured by a bonding agent such as glue or epoxy (not shown). Referring to  FIG. 3A , which shows a sectional view of the writing instrument  1 , of  FIG. 2  taken at the sectioning plane, and in the direction indicated by the section arrows  3 A- 3 A. This sectional view shows the initial position of the writing instrument  1 . Referring to  FIG. 3B , the subsequent view of  FIG. 3A , segment  2 A, in a subsequent moved position. The attached segments  2 A,  2 B, are tapered to a 45 degree angle  22 , to prevent interference with the swivel joint assembly  11 . Referring to  FIGS. 1-5A , the spherical center point of the swivel joint assembly  11 , pivots allowing approximately 360 degree range of free movement of attached segments  2 A,  2 B, The swivel joint assembly  11 , is encased in a single ply of heat shrink tubing  21 , 0.500 of an inch in diameter, 1.125 inches in length, and 0.0625 of all inch thick. The writing instrument  1  can be made in a variety of configurations colors, sizes, and core-element marking means  9 . Users can set the writing instrument  1  at a desired angle by pivoting one or both segments  2 A,  2 B, in order to reach within and mark upon surfaces as needed.
