摘要

A collapsible writing instrument including a first plate pair consisting of lateral and oppositely lateral plates having upper and lower ends; a first hinge interconnecting the lateral and oppositely plates' lower ends; a second plate pair consisting of an upper lateral plate and lower lateral plate having proximal and distal ends; second hinge interconnecting the lateral plate's upper end and the lower lateral plate's proximal end; a third hinge interconnecting the upper and lower lateral plates' distal ends; a third plate pair consisting of an upper oppositely lateral plate and a lower oppositely lateral plate having proximal and distal ends; a fourth hinge interconnecting the oppositely lateral plate's upper end and the lower oppositely lateral plate's proximal end; a fifth hinge interconnecting the upper and lower lateral plates' distal ends; and a pen cartridge attached to the upper lateral and upper oppositely lateral plates' proximal ends.

主权项

1. An ergonomic and collapsible writing instrument having a longitudinal dimension, said instrument comprising:
(a) a first plate pair comprising lateral and oppositely lateral plates, each plate among the first plate pair having upper and lower ends; (b) first pivoting means interconnecting the lateral and oppositely lateral plates' lower ends; (c) a second plate pair comprising an upper lateral plate and lower lateral plate, each plate among the second plate pair having proximal and distal ends; (d) second pivoting means interconnecting the lateral plate's upper end and the lower lateral plate's proximal end; (e) third pivoting means interconnecting the upper and lower lateral plates' distal ends; (f) a third plate pair comprising an upper oppositely lateral plate and a lower oppositely lateral plate, each plate among the third plate pair having proximal and distal ends; (g) fourth pivoting means interconnecting the oppositely lateral plate's upper end and the lower oppositely lateral plate's proximal end; (h) fifth pivoting means interconnecting the upper and lower oppositely lateral plates' distal ends; and (i) scribing means fixedly attached to the upper lateral and upper oppositely lateral plates' proximal ends.
