Training chopsticks

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.

1 . Chopsticks, comprising an upper chopstick member, a lower chopstick member and a hinge provided between the upper chopstick member and lower chopstick member, the hinge comprising a C-shaped element arranged on the lower chopstick member, and a hole and a pivot both arranged on the upper chopstick member, wherein the C-shaped element is hooked on the pivot so that the head of the upper chopstick member can rotate around the pivot, and wherein the diameter of the pivot is less than the inner diameter of the C-shaped element, such that the C-shaped element loosely hooks onto the pivot, allowing the upper chopstick member not only can rotate around the pivot, but can also turn sideway. 
     
     
         2 . The chopsticks according to  claim 1 , wherein further comprising an index finger ergonomic device, which is a projection extending from the back surface of the lower chopstick member, for touching the third section of the index finger at the chopsticks holding status. 
     
     
         3 . The chopsticks according to  claim 2 , wherein further comprising a first inclined plane from the projection, which inclines to the head of the lower chopstick member and directs to the upper chopstick member. 
     
     
         4 . The chopsticks according to  claim 2 , wherein further comprising a pillar, the bottom end of which connects to the lower chopstick member, and the top end of which extends to a position between the upper chopstick member and the lower chopstick member and connects to the projection. 
     
     
         5 . The chopsticks according to  claim 2 , wherein further comprising a thumb ergonomic device for touching the ulnar side of the thumb at the chopsticks holding status. 
     
     
         6 . The chopsticks according to  claim 5 , wherein the index finger ergonomic device and the thumb ergonomic device cooperate with each other, so as to maintain the relative position between the third section of the index finger and the thumb. 
     
     
         7 . The chopsticks according to  claim 5 , wherein the thumb ergonomic device is arranged on the lower chopstick member, and is structured as a protrusion protruding from the front surface of the lower chopstick member, a thumb insertion ring, a half barrel shaped member, or a barrel shaped member. 
     
     
         8 . The chopsticks according to  claim 5 , wherein the thumb ergonomic device is arranged on the upper chopstick member, and is structured as a protrusion protruding from the front surface of the upper chopstick member or a thumb insertion ring. 
     
     
         9 . The chopsticks according to  claim 5 , wherein the thumb ergonomic device is located at the upside of the front surface of the lower chopstick member and fixed to the lower chopstick member through a fixing element. 
     
     
         10 . The chopsticks according to  claim 9 , wherein the thumb ergonomic device has a curved surface which is open toward the head of the chopsticks. 
     
     
         11 . The chopsticks according to  claim 9 , wherein the thumb ergonomic device extends toward the lower chopstick member, reaching at or beyond the front surface of the lower chopstick member. 
     
     
         12 . The chopsticks according to  claim 2 , wherein the projection directly bulges from the back surface of the lower chopstick member.
