| Abstract: |
Two parallel chopsticks are interconnected by a transversely extending spring member which extends directly across between the two chopsticks to form a perpendicular extension from one chopstick which directly interconnects with the other chopstick. An ornamental design may extend from opposite edges of the transverse interconnecting member in a direction extending parallel to the chopsticks. The spring member is designed to give the correct feel for use of chopsticks. The cross-section of the spring member can be modified to give this correct feel. An additional feature is a guide locking member which interconnects the two chopsticks approximately at their mid-points.

| Claim |
I claim:
1. A chopstick assembly comprising:
- a pair of chopsticks,
- a spring member interconnecting said pair of chopsticks to space said chopsticks away from each other and for biasing one end of each of said chopsticks away from each other, and
- locking means interconnecting said pair of chopsticks (1) for resisting the bias of said spring member, (2) for preventing twisting of said chopsticks relative to each other and (3) for preventing excessive movement of said one end of said chopsticks away from each other which would cause breakage of said spring member,
- said locking means including a first projection extending laterally from one of said chopsticks towards the other of said chopsticks, a second projection extending laterally from said one chopsticks and towards said other chopstick, and a third projection extending laterally from said other chopstick towards said one chopstick,
- said first projection being U-shaped and having two legs interconnected at one end by a crosspiece, a free end of each of said two legs being connected to said one chopstick,
- said second projection extending parallel to said first projection and spaced from said first projection to form a gap,
- said third projection having, at a free end opposite to an end connected to said other chopstick, a hooked-shaped end extending perpendicular to said third projection, said hook-shaped end engaging said crosspiece due to the bias of said spring member on said chopsticks and said hook-shaped end being moveable to engage said one chopstick to limit movement of the chopsticks with respect to each other and said third projection being located in said gap between said first projection and said second projection and said third projection slidingly engaging said first projection and said second projection when said chopsticks are moved toward each other to prevent twisting of said chopsticks relative to each other.
