Abstract
Description
[Technical field]
[0001] This invention relates to a set of three chopsticks that is used by foreigners who are using chopsticks for the first time or elderly people who have some difficulty moving their fingers when eating Japanese food that requires chopsticks. [Background technology]
[0002] Traditionally, a pair of thin rods called issen were held in one hand, and food, mainly Japanese food, was picked up by pinching it near the tip and brought to the mouth. Incidentally, chopsticks and chopstick assisting tools that can effectively assist the opening movement of chopsticks are known (see Patent Document 1). Also, a clamping tool is known that can be easily operated even by people with impaired hands or those who are unfamiliar with the tool, and that is easy to handle during cleaning and the like (see Patent Document 2). Furthermore, traditional chopsticks are difficult for foreigners to use, and they tend to be unfamiliar with Japanese food and are avoided, so tweezers-type chopsticks that are easy to use are now known (see Patent Document 3).

[0003] [Patent Document 1] Patent No. 6910694 [Patent Document 2] Patent Publication No. 2021-053391 [Patent Document 3] JP2017-189566Publication Summary of the Invention [Problem to be solved by the invention]
[0004] With the traditional pair of thin, stick-like Issen chopsticks, it was impossible for foreigners using chopsticks for the first time or elderly people with some difficulty in moving their fingers to easily and comfortably bring difficult-to-pick Japanese foods to their mouths and eat them without the need for practice or skill. The present invention has been made in order to solve the above problems.
[0005] The chopsticks are equipped with a rectangular, flat, rounded thumb rest, on which the thumb rests, and two finger rests of the same shape and configuration, on which the index finger and middle finger rests, A first chopstick part, which is rod-shaped like conventional chopsticks, is provided at the center of the front end part of the thumb rest part, and a second chopstick part and a third chopstick part are provided on the left and right of the front end part of the two finger rest part, respectively. The first chopstick portion, the second chopstick portion and the third chopstick portion each have a joint portion near the rear end and a chopstick tip portion near the front end, A bifold connecting portion is provided at the rear end portions of the thumb rest portion and the two finger rest portions. The chopsticks are made up of three pieces and are a single unit.
[0006] To provide an invention that enables anyone to easily, comfortably and stably pick up food that is difficult for foreigners using chopsticks for the first time or elderly people with some handicap, without needing to become accustomed to chopsticks or to have operating skills, to bring it to their mouth and eat it, which was previously thought to be impossible. Also, there is no need for a chopstick rest when you are taking a chopstick rest. [Brief description of the drawings]

[0008] Hereinafter, an embodiment of the present invention will be described. First, the set of three chopsticks (1) of the present invention comes in three types: for right-handed adult men, adult women, and children, and three types for left hands. This embodiment will explain the right-handed chopsticks for adult men. Claim 1 (a) The chopsticks are equipped with a rounded, oval-like, flat thumb rest (3) for the thumb (O) and two finger rests (4) of the same shape for the index finger (H) and middle finger (N). (b) The chopstick body (2) is made of plastic or wood. (c) The thumb rest portion (3) and the two finger rest portion (4) are about 9 cm long, 4 cm wide, and 2 mm thick. (iv) A first chopstick part (5) is provided in the center of the front tip part of the thumb rest part (3) and has the same rod-like shape as conventional chopsticks. (e) A second chopstick portion (6) and a third chopstick portion (6) having the same shape and configuration as the first chopstick portion (5) are provided on the left and right positions of the front tip portion of the two finger rest portion (4). (f) The second chopstick portion (6) and the third chopstick portion (7) are spaced apart by a minimum of about 3 mm near the front tip and a maximum of about 1 cm near the rear tip. (g) The first chopstick part (5), the second chopstick part (6), and the third chopstick part (7) are about 9 cm long and made of plastic or wood, etc., in a round or square rod shape, with a chopstick tip part (8a) near the tapered tip on the front side and a connecting part (8) near the tip on the rear side. (h) Each of the connecting portions (8) forms the first chopstick portion (5) and the thumb rest portion (3) integrally, and forms the second chopstick portion (6) and the third chopstick portion (7) integrally with the two finger rest portion (4). (i) A connecting portion (9) is provided near the rear tip portion of each of the thumb rest portion (3) and the two finger rest portion (4) to fold the thumb rest portion (3) and the two finger rest portion (4) in half. Claim 2 (j) A vertically raised thumb holding portion (3a) for contacting the thumb (O) is provided near the center of the right edge of the surface of the thumb rest portion (3) toward the front. (k) The thumb holder (3a) is made of plastic or wood, has an elliptical shape with a length of about 3 cm, a height of about 1-5 cm and a thickness of about 2 mm, and is attached by adhesive or fitting. Claim 3 (l) A vertically raised finger holding portion (4a) to be held between the index finger (H) and middle finger (N) is provided near the center of the surface of the finger rest portion (4). (m) The two finger holding portion (4a) is made of plastic or wood, has an elliptical shape with a length of about 4 cm, a height of about 2 cm and a thickness of about 2 mm, and is attached by adhesive or fitting. Claim 4 (f) A rectangular control portion (9a) extending forward from the two bifold tip portions of the connecting portion (9) is provided facing each other on the back surfaces of the thumb rest portion (3) and the two finger rest portion (4). (Y) The control part (9) is about 5 cm long and 3-5 cm wide and is attached with adhesive. The present invention has the above-mentioned structure. When using the pair of chopsticks (1) of the present invention, the chopsticks are first placed on the table with the tips (8a) of the chopsticks' main bodies (2) facing forward. Next, the index finger (H) and middle finger (N) of the dominant hand (T) pinch the two-finger holding portion (4a) from the left and right and place it on the two-finger rest portion (4), and then the thumb (O) is abutted against the thumb rest portion (3) to support the thumb holding portion (3a) from below and maintain the posture. It is now ready for use. Next, with the tips of the thumb (O), index finger (H), and middle finger (N), close the thumb rest part (3) and the two finger rest part (4) as if you were picking up food (S), and pinch the food (S) with the tips of the three chopsticks (8a) to surround it, pick it up, and bring it to your mouth and eat it in the same way as with conventional chopsticks. This series of steps is simple and does not require any experience or skill, so anyone, regardless of age or gender, including foreigners using chopsticks for the first time, can enjoy a meal easily, comfortably, and with peace of mind. In addition, with the conventional pair of two chopsticks, small round foods (S) or thin, flat foods (S) that are difficult to pick up can be easily picked up by pinching them with the three chopsticks (1) of the present invention, as the three chopstick tips (8a) surround and pinch the food (S) and the number of contact points with the food (S) increases. Furthermore, the control unit (9a) prevents the thumb rest unit (3) and the two finger rest unit (4) from moving left and right when opening and closing, and the first chopstick unit (5), the second chopstick unit (6), and the third chopstick unit (7) can be moved accurately in a set trajectory, making it safe to use. Furthermore, when it is time to use the chopsticks for a chopstick rest, simply place them on either side, and the tips (8a) of the chopsticks will always be suspended in the air, eliminating the need for a chopstick rest, which is hygienic and secure.
