[0002]

2. Description of the Related Art It is considered that a proper way of holding chopsticks satisfies the following requirements (a) to (g). That is, (a) the lower chopsticks (hereinafter, referred to as "lower chopsticks") are partially clamped at the base of the thumb and the forefinger, and part of the chopstick tip is the first joint of the ring finger. Slightly supported on the upper flank.

(B) The upper chopsticks (hereinafter referred to as "upper chopsticks") have a part of the hand side extending from the abdomen near the second joint of the index finger to the abdomen of the fingertip or the abdomen near the first joint of the middle finger. And it is supported by being pinched lightly in the abdomen from the first joint of the thumb to the fingertip.

(C) The lower chopsticks are kept almost immobile.

(D) The operation of the chopsticks is mainly performed by moving the index finger and the upper chopsticks. At this time, the thumb is only applied lightly.

(E) The angle of the thumb from the chopstick tip side to the lower chopstick is 60 to 80 degrees.

(F) The angle of the thumb from the chopstick tip side to the upper chopstick is about 90 degrees.

(G) The degree of freedom of the index finger and the middle finger is largely guaranteed.

[0009] On the other hand, an example of an unfavorable way of holding chopsticks is that the lower fingernail cannot place the ring finger closer to the end of the chopstick than the thumb.

As a conventional training tool for holding chopsticks in consideration of such problems, for example, Japanese Utility Model Application Laid-Open No. 61-176578.
Is disclosed in Japanese Patent Application Laid-Open Publication No. HEI 9-203 (1995). As shown in FIG. 14, a spacer 53 interposed between an upper chopstick 51 and a lower chopstick 52 is sandwiched between a pair of wall bodies 54 and 55 on the practice device 50 for holding chopsticks. Upper side of back surface of 54/55 and spacer 5

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 FIGS. 1 to 12 show an embodiment of the present invention.
This will be described below.

As shown in FIG. 1, an exercise device 1 for holding chopsticks (hereinafter, abbreviated as "exercise device") 1 according to the present embodiment includes upper chopsticks H1 as upper chopsticks and lower chopsticks as lower chopsticks. H2, and two identical finger guide members 2.3 attached to the lower chopstick H2 at a predetermined interval.
It is composed of

The one finger guide member 2 is made of an elastic material such as rubber, soft resin or cork, for example, and is inserted into the lower chopstick H2 as shown in FIG. An outer peripheral portion 5 having an equilateral triangular shape is provided around the hole 4 that is bored.

The hole 4 is formed to be slightly smaller than the diameter of the lower chopstick H2, and combined with being formed of an elastic material such as rubber, the chopstick H having a different cross-sectional shape, for example, a cross-section described later. It can also handle chopsticks H having a triangular or hexagonal shape and chopsticks H having different thicknesses. Further, since the finger guide member 2 is formed of an elastic material such as rubber, soft resin, or cork, the finger guide member 2 has less uncomfortable feeling when held.

The finger guide member 2 has a projecting portion 6 projecting radially outward of the hole 4 from the outer peripheral portion 5. Then, as shown in FIG.
Both the rear surface 6a and the front surface 6b are formed substantially flat, so that the thumb or ring finger can be easily placed or abutted.

In this embodiment, both the rear surface 6a and the front surface 6b of the protruding portion 6 are formed substantially flat. However, the present invention is not limited to this. For example, at least the rear finger guide member 2 or the front surface 6b of the finger guide member 2 on the front side may be formed flat.

Further, in the finger guide member 2 described above, the outer peripheral portion 5 and the protruding portion 6 are formed by integral molding. However, the present invention is not limited to this. For example, FIGS. As described above, the outer peripheral portion 5 and the protruding portion 6 may be formed of different members, and these may be joined by bonding or the like.

On the other hand, the above chopsticks H are shown in FIGS.
As shown in (c), for example, three types having different lengths are prepared so as to be applicable to infants, school children and adults.

The length of the above chopsticks H is, for example, 225 mm,
195mm or 165mm, 1 each
It has a grip portion of the same thickness of 05 mm, 93 mm or 81 mm. The grip portion has a substantially equilateral triangular cross-sectional shape, and the distal end side of the grip portion has a circular cross-sectional shape. It is not always necessary to make the cross-sectional shape of the grip portion of the chopstick H different from that of the tip of the chopstick H as described above. For example, a triangular cross-sectional shape that gradually tapers throughout the length of the chopstick H may be used.

Further, the cross-sectional shape of the gripping portion is not necessarily limited to a triangle, and is not limited to a triangular shape as shown in FIGS.
As shown in the figure, a cross section of a regular hexagon is also possible.

On the other hand, the lower chopstick H2 in the above chopsticks H includes:
FIGS. 4A, 4B, and 5C and FIGS. 5A, 5B, and 5C.
As shown by oblique lines, interval marks 11 for specifying positions for attaching the finger guide members 2 and 3 are provided at predetermined intervals in accordance with the size of the hand.
The interval marks 11 are, for example, painted in color with lower chopsticks H2.
Is applied or printed in a belt shape over the entire circumference. Note that the coloring is not necessarily performed on the entire circumference of the lower chopstick H2, but may be performed only on each side surface of the lower chopstick H2 having a regular triangular cross section or a regular hexagonal shape, also serving as an angle mark described later. The interval mark 11 attached to the rear side of the lower chopstick H2 is the lower chopstick H
The position of approximately 1/4 of the length of 2 is inherently preferable as the position of the thumb of the lower chopstick H2.

Here, as shown in FIG. 1, the distance between the distance marks 11 indicates the distance at the correct position of the base of the flank of the thumb and the flank of the first joint of the ring finger.

That is, in order to hold the chopsticks H correctly, the predetermined interval L in the interval marks 11 is, as shown in FIG. 6, the point A between the base of the thumb and the base of the index finger and the middle finger. The distance from the point A between the base of the thumb and the index finger to the point C between the base of the thumb and the base of the index finger, which is larger than half the distance to the point B between the base of the ring and the base of the ring finger. It is preferred that the distance be less than half of.

That is, it is preferable that AB / 2 ≦ L ≦ AC / 2.

Therefore, in the present embodiment, the predetermined distance L in the distance marks 11 is set to be the above distance. Specifically, the length of chopstick H is
Since there are three types that can correspond to infants, school children, and adults, the typical size of infants is, for example, 30 mm, the typical size of school children is, for example, 35 mm, and the typical size of adults is, for example, 40 mm.

The finger guide members 2 and 3 attached to the lower chopstick H2 have the same shape, but the finger guide members 2 and 3 have the above-mentioned predetermined distance L and have the same configuration as shown in FIG. (B) As shown in (b), the projections 6 are attached so that they can face each other with a rotation angle of approximately 120 degrees.

In the present embodiment, the mutually protruding portions 6.6 of the finger guide members 2.3 are substantially one.
As shown in FIG. 8, for example, lower chopsticks H having a regular triangular cross section are used as angle marks for facing each other with a rotation angle of 20 degrees.
2 indicates the direction in which the protrusions 6 project, for example, A.
A is described. Note that the angle mark is not necessarily limited to A · A, but may be a number such as 1.1, or may be a picture of an animal or the like or a simple color painting. Similarly, the lower chopstick H2 with a regular hexagonal cross section also
A / A is described on every other side as the above-mentioned angle mark.

A method of using the training tool 1 having the above configuration will be described.

First, for example, as shown in FIG.
As shown in FIG. 1, finger guide members 2.3 are fitted to the color-marked interval markers 11 of the lower chopstick H2. At this time,
As shown in FIG. 8, the protrusions 6, 6 of the finger guide members 2, 3 are positioned so as to protrude so as to coincide with the side surfaces of A, A which are angle marks on the lower chopstick H2 of the equilateral triangle.

As a result, each of the protrusions 6
They can face each other with a rotation angle of 0 degrees.

Next, the lower chopstick H2 is sandwiched between the bases of the thumbs,
The outer side of the finger pad near the base of the thumb is arranged on the rear surface 6 a which is the contact surface with the finger guide member 2. Further, the finger pad near the tip of the ring finger is brought into contact with the front surface 6 b, which is the contact surface of the finger guide member 3. As a result, the finger guide members 2 and 3 are sandwiched between the thumb and the ring finger, the lower chopstick H2 is stably gripped, and the positional relationship between the lower chopstick H2 and the thumb / ring finger can be set correctly.

Next, the upper chopstick H1 is gripped by three fingertips of the thumb, the middle finger and the index finger. At this time, the thumb is the upper chopstick H1
Abdomen near the first joint of the thumb
Contact 1 That is, the relationship among the lower chopstick H2, the upper chopstick H1, and the thumb is generally set so as to maintain a triangle having an angle as shown in FIG.

By gripping the upper chopstick H1 in this manner, the positional relationship between the three fingers of the thumb, middle finger and index finger and the upper chopstick C1 is set, and a stable gripping state is obtained.
Can be freely operated with the index finger and the middle finger.

When using the training tool 1 described above,
As shown in FIG. 10, a finger guide member 20 having the same shape as the finger guide member 2 can be separately attached to the upper chopstick H1. This makes it possible to further stabilize the position of the upper chopstick H1 on the side of the thumb near the first joint. At this time, it is preferable that the mounting position of the finger guide member 2 on the upper chopstick H1 be about 5 mm from the mounting position on the rear side of the finger guide member 2 of the lower chopstick H2 on the tip side of the upper chopstick H1. This allows the tip of the upper chopstick H1 and the tip of the lower chopstick H2 to match when the correct chopstick H is held.

As described above, in the training device 1 of the present embodiment, the two finger guide members 2.3 have a predetermined interval L in the front and rear directions of the lower chopstick H2 according to the size of the hand, and Since the protrusions 6 are attached to each other so as to face each other with a rotation angle of approximately 120 degrees, the finger pad outer side near the base of the thumb with respect to the protrusion direction of each protrusion 6, 6, and The finger pad near the tip of the ring finger can be contacted so as to be substantially orthogonal. Therefore, since the outer side of the finger pad near the base of the thumb and the finger pad near the tip of the ring finger abut against the rear surface 6a or the front surface 6b in a stable state, the lower chopstick H2 is stably gripped and the lower chopstick H2 is constantly immobile. Can be kept in a state.

The attachment positions of the two finger guide members 2 and 3 have a predetermined distance L in the front and rear direction of the lower chopstick H2 according to the size of the hand with respect to an infant, a school child or an adult. Therefore, according to the size of each hand, the direction of the thumb and the direction of the fingertip up to the first joint of the ring finger can be made parallel to each other.
The lower chopstick H2 can be correctly held.

When holding the upper chopsticks H1, the training implement 1 of the present embodiment grips the lower chopsticks H2.
The three fingertips of the upper chopstick H1, the thumb, the middle finger and the index finger, can be easily guided.

By grasping the lower chopstick H2 and the upper chopstick H1 in this way, it is possible to easily learn how to hold a correct chopstick.

In addition, this training tool 1 includes a finger guide member 2 having a protrusion 6 on the lower chopstick H2 and a finger guide member 3 having the same shape.
The configuration is simple because only the components are attached. Therefore, there is not much feeling that the training tool 1 is attached to the lower chopsticks H2, so that the training tool 1 can be easily used and the cost can be reduced.

Further, since the finger guide members 2 and 3 can be fitted freely, the chopsticks H can be easily washed, and two finger guide members 2 and 3 are provided according to the learning stage of how to hold the chopsticks H correctly. Of the finger guide members 2 and 3 can be omitted.

Furthermore, since the finger guide members 2 and 3 can be freely fitted, by changing the direction of the protruding portions 6, 6, it is possible to cope with left-handed use.

That is, in the present embodiment, the rotation angle of the finger guide member 2 with respect to the finger guide member 3 is 120 degrees clockwise as viewed from the rear side of the lower chopstick H2, but is not limited to this. The rotation angle can be set to 120 degrees counterclockwise, which makes it possible to cope with a person holding the chopstick H with the left hand. In this case,
For a left-handed person, a chopstick H having an angle mark of 120 degrees in a counterclockwise direction is provided, or for example, a side face on which A is displayed as an angle mark on a lower chopstick H2 of an equilateral triangle. Different sides are marked with B and C angle markers, respectively, and right-handed persons align the protrusions 6.6 with the sides of the A and A angle markers, while left-handed persons mark A and B angle markers. It is desirable that the protruding portions 6, 6 be aligned with the side surfaces of the.

The predetermined distance L between the finger guide members 2 in the training tool 1 is between the point A between the base of the thumb and the base of the index finger and between the base of the middle finger and the base of the ring finger. The distance is greater than half the distance to point B and less than half the distance from point A between the base of the thumb and the base of the index finger to point C between the base of the ring finger of the palm. I have.

That is, the size of the hand of an infant, school child, adult or the like varies widely, but the predetermined distance L between the two finger guide members 2.3 attached in the front and rear directions of the lower chopstick H2 is as described above. By setting, the direction of the thumb and the direction of the fingertip up to the first joint of the ring finger can be made parallel, so that the lower chopstick H can be correctly held regardless of age or gender. Become. Also, the finger guide members 2 and 3
Since it can be fitted freely, it is possible to make fine adjustments so that the above-mentioned predetermined interval L is set according to the size of each person's hand.

The chopsticks H in the training device 1 are formed in a regular triangle or regular hexagonal cross section. Therefore, 2
When the mutually protruding portions 6.6 of the finger guide members 2 and 3 are fitted so as to face each other with a rotation angle of approximately 120 degrees, the chopstick H having an equilateral triangular cross section is attached to each of the adjacent side surfaces. If the protruding parts 6, 6 are installed, both are inevitably 12
They face each other with a rotation angle of 0 degrees. In the case of chopsticks H having a regular hexagonal cross section, the projections 6
Is inevitably arranged so as to face each other with a rotation angle of 120 degrees.

Therefore, the projections 6, 6 of the two finger guide members 2, 3 can be easily opposed to each other so as to have a rotation angle of 120 degrees.

The lower chopstick H2 of the training tool 1 has an equilateral triangular or hexagonal cross section, and has a predetermined distance L according to the size of the hand. Marks 11 are provided.

Therefore, when the two finger guide members 2.3, which can be freely fitted to the lower chopstick H2, are fitted to the space marks 11,
By fitting according to 11, the interval between the two finger guide members 2 and 3 can be inevitably set to the predetermined interval L according to the size of the hand.

As a result, the interval between the two finger guide members 2 and 3 can be easily set to the predetermined interval L according to the size of the hand.

The lower chopstick H2 of the training tool 1 has an equilateral triangular or hexagonal cross section, and the protruding portions 6.6 of the two finger guide members 2.3 are opposed to each other with a rotation angle of approximately 120 degrees. Angle marks such as A and A are provided to indicate the installation direction of the protruding portions 6 to be disposed.

Therefore, when the two finger guide members 2.3, which can be freely fitted to the lower chopstick H2, are fitted according to the angle mark, the two finger guide members 2, necessarily.
The protrusions 6 at 3 have a rotation angle of approximately 120 degrees.

As a result, the two finger guide members 2.3 can be easily fitted to the lower chopstick H2 so that the projecting portions 6.6 have a rotation angle of approximately 120 degrees.

Note that the present invention is not limited to the above embodiment, and various changes can be made within the scope of the present invention. For example, in the above embodiment, the finger guide member 2
Has a substantially triangular outer peripheral portion 5, but is not particularly limited thereto. For example, as shown in FIGS. 11 and 12, a circular outer peripheral portion 5 can be used.
Further, the protruding portion 6 is not limited to a square shape, but may have a curved shape as shown in FIG.

Further, in this embodiment, three types of different lengths for infants, school children, or adults are prepared, but the present invention is not limited to this, and one adult length chopstick is used. By attaching various interval marks 11 and angle marks for infants, school children or adults to H, it is possible for the whole family to practice how to hold chopsticks correctly, for example.
