Abstract

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.

Claims

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.

2. The ergonomic and collapsible writing instrument of claim 1 wherein the first, second, third, fourth, and fifth pivoting means are adapted for facilitating plate pair flexing and extending movements among the first, second, and third plate pairs;

said flexing and extending movements being between a T configuration and a collapsed configuration, the lateral, oppositely lateral, lower lateral, upper lateral, lower oppositely lateral and upper oppositely lateral plates moving toward the T configuration upon the flexions of the first, second, and third plate pairs, and said plates moving toward the collapsed configuration upon the extensions of said plate pairs.

3. The ergonomic and collapsible writing instrument of claim 2 wherein the pivoting means comprise hinges selected from the group consisting of living hinges, pin and sleeve hinges, and snap lug and snap socket hinges.

4. The ergonomic and collapsible writing instrument of claim 3 wherein the scribing means comprise a line drawing implement selected from the group consisting of ballpoint pens, felt-tipped pens, felt-tipped markers, paint pens, touch screen styluses, and mechanical pencils.

5. The ergonomic and collapsible writing instrument of claim 4 wherein each plate among the lateral, oppositely lateral, upper lateral, lower lateral, upper oppositely lateral and lower oppositely lateral plates is composed of plastic.

6. The ergonomic and collapsible writing instrument of claim 5 wherein the proximal ends of the upper lateral and the upper oppositely lateral plates form a longitudinally extending sleeve.

7. The ergonomic and collapsible writing instrument of claim 6 wherein the line drawing implement is nestingly received within the longitudinally extending sleeve.
