Description:
STUDYING CHOPSTICKS FOR DEVELOPING CHILDREN'S INTELLECTUAL POWERS BACKGROUND OF THE INVENTION (1) Field of the Invention The present invention relates to chopsticks for developing intellectual faculties, more particularly to a pair of training chopsticks having a removable coupling member formed between the upper sides of the first and the second stick, a thumb-inserting hole formed on the first stick, a forefinger and second finger-inserting hole formed on the second stick, and removable pads for picking up solids formed on the lower sides of the first and the second stick. The training chopsticks are of good use to novice or child users who make poor use of chopsticks.

(2) Description of the Related Arts Chopsticks, widely used throughout Asia as an eating utensil, are effective in exercising the joints of fingers or wrists. Moreover, chopsticks are known to be effective in developing children's intelligence, specially, during their growth period, since the moving of fingers can arouse their brains.

However, chopsticks can be difficult and frustrating to use for novice users suffering from a disability, and are rarely used by children.

A number of inventions have been developed to assist the use of chopsticks. The Japanese Patent specification of No. 10-137101

describes a pair of training chopsticks on which rings for inserting fingers are formed. Referring to Fig. 1, the rings 11,12, 21,22 are formed on the chopsticks 10,20, and inclined to insert fingers suitably. Marks for indicating the finger to be inserted into each ring are recorded on the rings, and arrows are marked on each top of the chopsticks in order to indicate the direction for grasping.

However, since the rings 21,22 are fixed on the chopsticks, the chopsticks should be made in various form according to the size of the fingers. Further, it is difficult to insert fingers into the rings, since the inserting angle for the rings is steep.

Korea utility model No. 2001-23369 describes more improved training chopsticks. Referring Fig. 2, the upper sides of the chopsticks 50a, 50b are connected to each other by a connecting pin 51 including the hinge 51'. A grasp hole for the thumb 51 is formed on the chopstick 50a, and a grasp hole for the forefinger 52 and a grasp hole for the second finger 53 are formed on the other chopstick 50b. The grasp holes 51,52, 53 are inclined to the chopsticks to fit the inserting angle of the fingers. A grasping unit 55 has the grasp hole for the forefinger 52 and the grasp hole for the second finger 53 which are formed in a body. A male screw 55b is formed on the outside of the chopstick 50b and a female screw 55a is formed on the inside of the grasping unit 55, so that the fixing position of the grasping unit 55 can be adjusted to fit the finger size of users.
