| Claim |
I claim:
1. In a chopsticks assembly,
- (a) a pair of elongated chopsticks,
- (b) pivot means interconnecting the chopsticks to allow scissors pivoting thereof in generally the same plane, and about a pivot axis, the chopsticks each including a handle at one longitudinal side of the pivot means, and a tong at the opposite longitudinal side of the pivot means,
- (c) a spring biasing the chopsticks to a spread apart position and allowing finger pivoting thereof toward a closed position so that the tongs may pick-up an edible,
- (d) retention means to releasably retain the chopsticks in said closed position, said retention means including a shallow protrusion on one handle and a shallow recess on the other handle to releasably receive the protrusion when the handles are closed together, said recess and protrusion having associated interengageable detent shoulders in spaced relation to the pivot means, said shoulders characterized as interfitting in such shallow and loose configuration as to be freed of interengagement in response to impact jarring of the closed together tongs,
- (e) the handles extending in overlapping relation in the direction of the pivot axis, as the handles pivot, the tong and handle of each chopstick having a juncture at which they extend in offset V-shaped configuration, in spaced relation to said pivot means, the closed together tongs having a rectangular outline, and the closed together handles having a rectangular outline, and
- (f) the spring being a torsion spring with arms extending in recesses defined by the handles proximate said pivot axis, said recesses and arms therein extending in the elongation direction of the chopsticks,
- (g) the tongs defining a common plane, normal to said axis, and the chopsticks interfitting in said closed position, with the handles extending in face to face relation in a first direction parallel to said axis, and the tongs extending in face to face relation in a second direction normal to said first direction.
