Abstract

A chopstick manipulator comprises a bridge and clamps. Each clamp includes an inner support having an inner surface where an upper half of the inner surface has a mid portion so the bridge interconnects each mid portion thereof, a rear support extending from a rear end of the inner support so that about a right angle is formed by each outer surface of the inner and rear supports, and a distal support extending substantially forward from an outer end of the rear support while forming a substantially prismatic shape. The distal support is defined by an outer surface, a rearward slant surface and a forward slant surface so that a prismatic ridge by the respective slant surfaces approaches the outer surface of the inner support where an angle by the rear support and the rearward slant surface is less than 90 degrees.

Claims

1. A chopstick manipulator comprising;

a) a bridge; and

b) first and second clamps being symmetric to each other, wherein said each clamp includes;

(i) an inner support being a plate, wherein the bridge interconnects each inner surface of the inner supports;

(ii) a rear support being another plate and extending from a rear end of the inner support so that about a right angle is formed by each outer surface of the inner and rear supports; and

(iii) a distal support extending substantially forward from an outer end of the rear support while forming a substantially prismatic shape, wherein the distal support is defined by an outer surface, a rearward slant surface and a forward slant surface so that a prismatic ridge by the respective slant surfaces approaches the outer surface of the inner support, wherein at least one indentation is formed in and along said each prismatic ridge, wherein an angle by the rear support and the rearward slant surface of the distal support is less than 90 degrees.

2. The chopstick manipulator of claim 1 wherein the bridge is substantially domed to become upwardly waved.

3. The chopstick manipulator of claim 2 wherein the bridge has a thickness and a width, wherein said each inner support is less in thickness than the bridge.

4. The chopstick manipulator of claim 1 wherein the rearward slant surface is substantially larger in size than the forward slant surface.

5. The chopstick manipulator of claim 1 wherein each front side end of the inner supports is outwardly tapered to facilitate chopstick clamping by the clamps.

6. The chopstick manipulator of claim 1 wherein said each prismatic ridge is linearly straight.

7. The chopstick manipulator of claim 1 wherein said each prismatic ridge is parallel to the corresponding inner support.

8. A chopstick manipulator comprising:

a) a bridge; and

b) first and second clumps being symmetric to each other, wherein said each clamp includes;

(i) an inner support being a plate and having an inner surface, wherein an upper half of the inner surface has a mid portion, wherein the bridge interconnects said each mid portion of the inner surfaces of the inner supports;

(ii) a rear support being another plate and extending from a rear end of the inner support so that about a right angle is formed by each outer surface of the inner and rear supports; and

(iii) a distal support extending substantially forward from an outer end of the rear support while forming a substantially prismatic shape, wherein the distal support is defined by an outer surface, a rearward slant surface and a forward slant surface so that a prismatic ridge by the respective slant surfaces approaches the outer surface of the inner support, wherein at least one indentation is formed in and along said each prismatic ridge, wherein an angle by the rear support and the rearward slant surface of the distal support is less than 90 degrees.

9. The chopstick manipulator of claim 8 wherein the bridge is substantially darned and upwardly waved.

10. The chopstick manipulator of claim 9 wherein the bridge has a thickness and a width, wherein said each inner support is less in thickness than the bridge.

11. The chopstick manipulator of claim 8 wherein the rearward slant surface is substantially larger in size than the forward slant surface.

12. The chopstick manipulator of claim 8 wherein each front side end of the inner supports is outwardly tapered to facilitate chopstick clamping by the clamps.

13. The chopstick manipulator of claim 8 wherein said each prismatic ridge is linearly straight.

14. The chopstick manipulator of claim 8 wherein said each prismatic ridge is parallel to the corresponding inner support.
