Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assisting tool which can be attached to a pair of chopsticks so that they can be used as chopsticks in a very natural style.

[0002]

2. Description of the Related Art Apart from clumsiness and clumsiness, it is becoming more difficult for younger people to hold and operate chopsticks correctly. The use of forks and spoons since childhood has spurred this. On the other hand, chopsticks are regarded as a weak tool by foreigners other than Orientals. Many proposals have been made so far for instruments that are attached to chopsticks to practice and correct how to hold them properly. However, they have a complicated structure and are difficult to put on and take off, and in the case of a simple mechanism, there are inconveniences such as a limitation in the direction of movement and a special practice tool, and they are not widely used.

[0003]

DISCLOSURE OF THE INVENTION The present invention has a simple structure and can be easily mounted without modifying the main body of the chopstick, and can be used as an orthodontic practice tool as it is. The movement is natural and there is no discomfort in the fingers,
To provide a proper tool for holding chopsticks so that one of the chopsticks can swing freely in the direction in which both chopsticks are lined up.

[0004]

In order to achieve the above object, the present invention provides a reference chopstick insertion portion (2) and a moving chopstick insertion portion (3) having insertion holes (2a) and (3a) at the upper end of chopsticks. ) Is integrally formed. Then, the previous insertion hole (3a) of the chopstick insertion part (3) is provided with a corrugated bent body (4) in a transverse direction inside the chopstick insertion part (3), and the vertical direction is not bent but the vertical direction. The corrugated body (4) is bent, and the wavy body (4) acts as a rotation axis in the longitudinal direction, and the ring (3b) is mounted on the ring (3b) so that the swing movement can be freely performed. An auxiliary tool (1) is configured.
As the material, it is desirable that the whole is made of plastic from the viewpoint of its elasticity and manufacturing of the wavy bent body. Further, in the above structure, the chopsticks proper holding aid (1) is formed by inclining the moving chopsticks insertion part (3) downward at an obtuse angle with respect to the reference chopsticks insertion part (2).

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION As shown in the plan view of FIG. 1, when the AA direction is the longitudinal direction and the BB direction is the transverse direction, the wavy bending body (4) is provided in the BB direction rather than the AA direction. The wavy bent body is used because the movement of the chopsticks inserted into the moving chopstick insertion part (3) can be freely swung about the wavy bent body (4) together with the ring (3b). B for chopsticks
When a force acting in the B direction is exerted, one side of the wavy bending body (4) becomes the extension of the spring, and the other side becomes the contraction of the spring, and the mutual forces are exerted toward the center of the moving chopstick insertion part (3). Brake,
This is because the outer circle of the chopstick insertion part (3) keeps a concentric circle with the ring (3b) while always complementing the force.

Next, the wavy bent body (4) is formed in the BB direction and in the left-right direction, that is, the so-called longitudinal direction. This is because the movement of the chopsticks inserted into the moving chopstick insertion part (3) can freely swing around the wavy bending body (4) as a rotation axis together with the ring (3b). If the chopsticks are formed in the left-right direction, that is, in the vertical direction, the degree of freedom of swinging the chopsticks is increased, and the chopsticks are easy to move freely.

If the height of the wavy bent body (4) is the same as the height of the moving chopstick insertion portion (3), the anti-rotational force against the rotational force is large and it is difficult to freely move the chopsticks. It is preferable to make it smaller than the insertion portion (3) to increase the degree of freedom of swinging.

Further, it is appropriate that the number of bending cycles of the wavy bending body (4) is about 2 in terms of the degree of freedom of swinging. When the number of bending cycles is large, the degree of freedom in the up-down direction is added and is small. As in the case, the degree of freedom in swinging is reduced in both cases.

The chopsticks provided with the corrugated bending body (4) in the transverse direction of the BB and inserted into the moving chopsticks insertion portion (3) are the ring (3b).
Together with this, the wavy bending body (4) freely forms a swinging motion, the wavy direction is bent in the AA longitudinal direction, and its height is about 1/2 of that of the chopstick insertion part (3). age,
Bending is formed in about 2 cycles to give durability and flexibility.

The material is PE, PP, in order to form a flexible plastic molding which has good fluidity to the mold.
Made of PET and other materials that are safe for children to put in their mouths.
In addition, the moving chopsticks insertion part (3) with respect to the reference chopsticks insertion part (2)
Obliquely tilting downward is intended to generate chopstick length and food gripping force between both chopsticks within 10 °, especially 5-7
Let be °.

1 to 3, (2) is a reference chopstick insertion portion, and (3) is a chopstick insertion portion integrally formed with the reference chopstick insertion portion (2) with an obtuse downward inclination. In (3), there are insertion holes (2a) and (3a) at the upper end of the chopsticks.

Then, the previous insertion hole (3a) of (3) has a wavy bent body (4) in the transverse direction inside the moving chopstick insertion part (3).
Moreover, the wavy bending body (4) functions as a rotation axis in the longitudinal direction, and the ring (3b) is attached so as to allow swinging movement freely. ), The correct holding aid for chopsticks according to the present invention (1) is constructed. The material shall be plastic as a whole.

[0013]

Now, in order to use the assisting tool of the present invention, as shown in FIG. 4, the reference chopstick insertion portion is provided at the upper end portion of the reference chopsticks (chopsticks indicated by the valley between the thumb and forefinger and the ring finger). (2)
Of the moving chopstick insertion part (3) at the upper end of the moving chopsticks (the chopsticks that are moved in the direction between the index finger and the middle finger while holding them with the thumb). Hole (3
Insert a) and connect both chopsticks.

That is, the attachment to the chopsticks is extremely easy. As shown in FIG. 5, since it is attached to the upper end of the chopsticks, the chopsticks are grasped in the same natural style as before and the chopsticks are moved in the same manner. Then, the reference chopsticks and the moving chopsticks move in the sandwiching direction with respect to the reference chopstick while the upper ends of the connected chopsticks hold a predetermined interval between the insertion holes (2a) and (3a).

At this time, in the structure in which the moving chopsticks insertion part (3) is inclined downward at an obtuse angle with respect to the reference chopsticks insertion part (2),
Since the tips of both chopsticks come in close contact with each other at the start point, the movement in the pinching direction can be performed more smoothly.

More specifically, the moving chopstick is provided with a wavy bent body (4) at the upper end thereof in the transverse direction inside the moving chopstick insertion part (3), and is formed by bending in the longitudinal direction instead of bending in the vertical direction. Furthermore, since the corrugated bent body (4) functions as a rotation axis in the longitudinal direction, the wavy bent body (4) is inserted into the insertion hole (3a) of the ring (3b) mounted so that the swinging movement can be freely performed as this axis. The movable chopsticks can be freely tilted by the swinging action of the wavy bending body (4) without being displaced with respect to the reference chopsticks. Specifically, the target object can be accurately grasped and carried to the mouth. In both the grasping state and the operating state, since the fingers do not touch the assisting tool, there is no discomfort. It can be used not only as a training tool but also as a regular item. The simple structure and inexpensive mass production are also major advantages.
