Benefits of technology

[0041]Providing a hinge on chopsticks is a known idea. A current hinge for chopsticks is shown in FIG. 28, and includes a C-shaped element arranged on the lower chopstick member, and a hole 90 and a pivot 91 both arranged on the upper chopstick member. Starting from the existing hinge, the present invention designs a new hinge (as shown in FIG. 29), where the diameter of the pivot is intentionally made to be smaller than the inner diameter of the C-shaped element, enabling the C-shaped element loosely hooks onto that pivot.

Example

[0064]In the followings the present invention will be described in details with reference to the Figures.

[0065]In the first example (as shown in FIG. 5), an ergonomic device 133 for the thumb is separated from the lower chopstick member 20, and fixed on the upside of the front surface of the lower chopstick member through a fixing element 131 (e.g., a pillar) at a position between the upper chopstick member and the lower chopstick member. The thumb ergonomic device is formed in a curved shape, and opens towards the head 28 of the chopsticks in order to prevent the ulnar side of the thumb from deflecting excessively to the tail 29 of the lower chopstick member, thus avoiding the distorted chopsticks holding posture as shown in FIG. 3. Because this thumb ergonomic device is fixed relative to the lower chopstick member, it can help the thumb to maintain at a correct position with respect to the lower chopstick member. Also, the ergonomic device does not directly contact the lower chops...

Abstract

A pair of training chopsticks comprises an upper chopstick member and a lower chopstick member. A thumb ergonomic device is provided, which does not directly contact the lower chopstick member, but fixed at the upside of the front surface of the lower chopstick member through a fixing element. The thumb ergonomic device is shaped in a curve, the opening of which substantially directs to the head of chopsticks, so that when the chopsticks are held, the curve opening touches a region of the ulnar side of the thumb not touching the lower chopstick member, for maintaining the correct relative position between the thumb and the lower chopstick members.
