DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chopstick for practicing how to hold chopsticks for correcting the way of holding chopsticks in a short period of time and learning the correct way of holding the chopsticks.

[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 index finger, and the part of the chopstick tip is the first ring finger. It is supported at the upper part of the flank slightly ahead of the joint. (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 the thumb. Is supported by being slightly clamped in the abdomen from the first joint 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 chopsticks is 60
~ 80 degrees. (F) The angle of the thumb to the upper chopsticks as viewed from the end of the chopsticks is about 9
0 degrees. (G) The degree of freedom of the index finger and the middle finger is largely guaranteed.

[0003] On the other hand, an example of an unfavorable way of holding chopsticks is that the lower fingertip cannot place the ring finger located closer to the end of the chopstick than the thumb.

[0004] 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. 11, the training tool 50 for holding chopsticks includes an upper chopstick 51 and a lower chopstick 5.
2 and a spacer 53 interposed between the pair of wall members 54.
It is pinched at 55.

[0005] The chopstick holding training device 50 includes upper edges of the back surfaces of the walls 54 and 55 and upper ends 53 a of the spacers 53.
Are formed, and a lower chopstick supporting groove 57 is formed which is surrounded by lower back sides of the walls 54 and 55 and lower ends of the spacers 53.

Further, a thumb-side abdominal abutment piece 58 is formed so as to protrude near the chopstick hand of one wall 55, and a ring finger fixing portion 59 is formed on the other wall 54 near the chopstick tip. A lower chopstick fixing member 60 is removably fitted between the walls 54 and 55 forming the lower chopstick support groove 57.

[0007] Thus, the ring finger can be placed at the correct position, and the other fingers are also set at the correct position, so that it is possible to learn how to hold the chopsticks correctly.

[0008]

However, in the above-mentioned conventional training tool for holding chopsticks, since the upper chopsticks 51 are along the upper chopstick supporting grooves 56, the upper chopsticks 51 are restrained by the upper chopstick supporting grooves 56, and There is a problem that the degree of freedom of the chopsticks 51 is reduced.

In addition, the chopstick holding training device 50 is formed as a relatively large item that fits in the hand, so that the sense of holding the chopstick holding training device 50 is better than the feeling of holding the chopsticks. It is emphasized and has a problem that it is not very desirable as a training tool.

On the other hand, there is a so-called basting chopstick as a holding practice chopstick, which is insufficient as a structure for learning a proper way of holding the chopstick.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and has as its object to provide a holding practice chopstick that has a simple structure and can be easily learned to hold a correct chopstick. Is to do.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

As shown in FIG. 1, the holding practice chopsticks 1 (hereinafter, abbreviated as "practice chopsticks") 1 in the present embodiment are composed of a pair of chopsticks H composed of an upper chopstick H1 and a lower chopstick H2. The lower chopstick H2 is composed of two chopstick rear protruding members 2 and chopstick tip protruding members 3 which are finger guide members integrally formed at a predetermined interval.

The chopstick-side protruding member 2 and the chopstick-tip protruding member 3 are made of an elastic material such as rubber, soft resin or cork, and have the same shape. As shown in FIG. 2A, an outer peripheral portion 5 having, for example, a regular triangular shape is provided around a hole 4 formed so as to be inserted into and fitted to the lower chopstick H2.

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. Can also handle chopsticks H of triangular or hexagonal shape and chopsticks H of different thicknesses. Further, since the chopstick-side protruding member 2 and the chopstick-tip protruding member 3 are formed of an elastic material such as rubber, soft resin, or cork, the feeling of discomfort when held is reduced.

The chopstick-side protruding member 2 and the chopstick-tip protruding member 3 have a protruding portion 6 protruding outward from the outer peripheral portion 5 in the radial direction of the hole 4. And FIG.
As shown in (b), the upper surface 6a and the lower surface 6b of the protrusion 6
Are formed substantially flat, and thereby,
The thumb or ring finger can be easily placed or abutted. The upper surface 6a of the chopstick rear-side protruding member 2 is a rear end surface of the present invention, and the lower surface 6b of the chopstick tip-side protruding member 3 is a front end surface.

In this embodiment, both the upper surface 6a and the lower 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 upper surface 6a or the lower surface 6b is formed. It is sufficient that only one of them is formed flat.

Further, the chopstick-side protruding member 2 and the chopstick-tip protruding member 3 have a regular triangular outer peripheral portion 5 around the hole 4 and are integrated with the lower chopstick H2 with an adhesive or the like. , But is not necessarily limited thereto, and may be formed integrally with the lower chopstick H2. In this case, the elasticity is based on the material of the chopstick H.

On the other hand, the chopstick H for attaching and fixing the chopstick rear projecting member 2 and the chopstick tip projecting member 3 is shown in FIG.
(B) 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. In addition, each 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. Note that the chopsticks H
It is not necessary to make the cross-sectional shape different between the gripper and the tip side.
For example, it may have a triangular cross-sectional shape that gradually tapers throughout the length of the chopsticks H.

The cross-sectional shape of the gripping portion is not necessarily limited to a triangle, but may be any of FIGS. 4 (a), 4 (b) and 4 (c).
As shown in the figure, a cross section of a regular hexagon is also possible.

On the other hand, the lower chopsticks H2 of the chopsticks H are shown in FIGS. 3 (a), (b) and (c) and FIGS. 4 (a) and (b).
At the mounting positions 11 and 11 indicated by oblique lines in (c),
The chopstick-side projecting member 2 and the chopstick-tip projecting member 3 are attached.

The mounting position 11 on the rear side of the lower chopstick H2
Is essentially a quarter of the length of the lower chopstick H2, which is inherently preferable as the position of the thumb on the lower chopstick H2.

Here, as shown in FIG. 1, the distance between the mounting positions 11 and 11 depends on the distance at the correct position of the flank base of the thumb and the flank of the first joint of the ring finger according to the size of the hand. This is a predetermined interval.

That is, in order to hold the chopsticks H correctly, the predetermined interval L at the above-mentioned mounting positions 11 and 11 is required to be as shown in FIG.
As shown in FIG. 5, the distance from the point A between the base of the thumb and the base of the index finger to the point B between the base of the middle finger and the base of the ring finger is larger than half, and the base of the thumb and the base of the index finger are larger. The distance is preferably smaller than half the distance from point A to point C to the base of the ring finger on the palm.

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

Therefore, in the present embodiment, the predetermined distance L at the mounting positions 11 is set to be the above distance. Specifically, the length of the chopsticks H is three types that can correspond to infants, school children, and adults, respectively.
The typical size of school children is, for example, 35 mm, and the typical size of adults is, for example, 40 mm.

The chopstick-side protruding member 2 and the chopstick-tip protruding member 3 attached to the lower chopstick H2 have the above-mentioned predetermined distance L, and as shown in FIGS. 6 (a) and 6 (b). The projections 6 are integrally fixed so as to face each other with a rotation angle of about 120 degrees.

Note that the approximately 120 degrees is, for example, 90 degrees to 150 degrees as an allowable range, and preferably 1 degree.
05 degrees to 135 degrees, and optimally 115 degrees to 125 degrees.

Next, a method of using the practice chopsticks 1 having the above configuration will be described. First, as shown in FIG. 1, the lower chopstick H2 is sandwiched between the bases of the thumbs, and the outer side of the finger pad near the base of the thumbs is an upper surface 6a which is a contact surface with the chopstick rear projecting member 2.
Place on top. Further, the finger pad near the tip of the ring finger is brought into contact with the lower surface 6b, which is the contact surface of the chopstick tip side projecting member 3.
As a result, the chopstick rear projecting member 2 and the chopstick tip projecting member 3 are sandwiched between the thumb and ring finger, the lower chopstick H2 is stably gripped, and the positional relationship between the lower chopstick H2 and the thumb / ring finger is correct. Can be set.

Next, the upper chopstick H1 is gripped by three fingertips of the thumb, the middle finger and the index finger. At this time, the abdomen near the first joint of the thumb is brought into contact with the upper chopstick H1 so that the thumb is orthogonal to the upper chopstick H1. That is, the lower chopstick H2 and the upper chopstick H
The relationship between 1 and the thumb is generally set to maintain a triangle with 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, the middle finger, and the forefinger and the upper chopstick H1 is set, and a stable gripping state is achieved, and the upper chopstick H1 is held between the forefinger and the middle finger. Can be operated freely.

When using the practice chopsticks 1, as shown in FIG. 8, a finger guide member 20 having the same shape as the chopstick rear projecting member 2 is separately attached to the upper chopstick H 1. Is preferred. 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, the mounting position of the finger guide member 20 on the upper chopstick H1 is about 5 mm from the mounting position of the lower chopstick H2 on the rear side of the rear chopstick protruding member 2 of the lower chopstick H2. Is preferred. As a result, when the correct chopstick H is held, the tip of the upper chopstick H1 and the tip of the lower chopstick H2 match.

As described above, in the practice chopsticks 1 of the present embodiment, the chopsticks rear projecting member 2 and the chopstick tip projecting members 3 are arranged in the front and rear directions of the lower chopstick H2 at a predetermined distance L according to the size of the hand. And each of the protrusions 6 are attached with a rotation angle of about 120 degrees, so that the chopstick-side protruding members 2 and the chopstick-side protruding members 3 project in the protruding direction. The outer side of the finger pad near the base of the thumb and the finger pad near the tip of the ring finger can be contacted and guided so as to be substantially orthogonal.

Therefore, 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 upper surface 6a or the lower surface 6b in a stable state, so that the lower chopstick H2 is stably gripped and the lower chopstick H2 is held. H2 can be kept constantly immobile.

The mounting positions of the chopstick rear side protruding member 2 and the chopstick front side protruding member 3 have a predetermined interval L in the front and rear direction of the lower chopstick H2 according to the size of the hand with respect to an infant, school child or adult. Therefore, 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 according to the size of each hand. You can have it correctly.

Next, while the lower chopstick H2 is in this gripping state, the upper chopstick H1 is gripped by three fingertips of the thumb, the middle finger and the index finger. At this time, the abdomen near the first joint of the thumb is brought into contact with the upper chopstick so that the thumb is orthogonal to the upper chopstick.

Here, in the present embodiment, by grasping the upper chopstick H1 as described above, the three fingertips of the upper chopstick H1, the thumb, the middle finger and the index finger, can be easily and naturally guided. . In addition, by this, the positional relationship between the three fingers of the thumb, the middle finger and the index finger and the upper chopsticks is set,
A stable gripping state is achieved, and the upper chopstick H1 can be freely operated with the index finger and the middle finger.

As a result, it is possible to easily hold the correct chopsticks by learning the correct way of holding the chopsticks.

On the other hand, the training chopsticks 1 are simple in configuration because only two chopstick-side projecting members 2 and chopstick-tip projecting members 3 of the same shape are attached. Therefore, there is not much feeling that the training tool is attached to the lower chopstick H2, so that it is easy to be familiar and the cost can be reduced.

In the present embodiment, the rotation angle of the chopstick-side protruding member 2 with respect to the chopstick-tip protruding member 3 is the lower chopstick H2.
Is 120 degrees clockwise as viewed from the rear side, but the rotation angle is not necessarily limited to 120 degrees and can be set to 120 degrees counterclockwise. Can also be handled.

In the training chopsticks 1 of the present embodiment, the predetermined distance L between the chopstick-side protruding member 2 and the chopstick-tip protruding member 3 is:
A point greater than half the distance from point A between the base of the thumb and the base of the index finger to point B between the base of the middle finger and the base of the third finger, and between the base of the thumb and the base of the index finger Point C between A and the base of the ring finger on the palm
Is less than half the distance to

That is, the size of the hands of infants, school children, adults and the like varies widely, but the two chopstick rear projecting members 2 and the chopstick tip projecting members 3 attached to the front and rear directions of the lower chopstick H2.
By setting the predetermined distance L in this way, the direction of the thumb and the direction of the fingertip up to the first joint of the ring finger can be made parallel, whereby the lower chopstick H can be securely held regardless of age or gender. You will be able to hold it correctly.

The chopsticks H in the practice chopsticks 1 are formed in an equilateral triangle or a regular hexagon. Therefore,
When the chopsticks H having the regular triangular cross section are mounted so that the protruding portions 6.6 of the chopstick rear protruding member 2 and the chopstick front protruding member 3 are opposed to each other with a rotation angle of about 120 degrees,
If the protruding portions 6 are provided on each of the adjacent side surfaces, they will inevitably face each other with a rotation angle of 120 degrees. In the case of chopsticks H having a regular hexagonal cross section, if the protruding portions 6, 6 are provided on each of the side surfaces on which one is placed, both of them are inevitably 120
They face each other with a rotation angle of degrees.

Accordingly, the two protruding portions 6, 6 of the chopstick-side protruding member 2 and the chopstick-tip protruding member 3 can be easily opposed to each other so as to have a rotation angle of 120 degrees, thereby facilitating manufacture. It is.

It should be noted 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-described embodiment, the chopstick-side protruding member 2 and the chopstick-side protruding member 3 have the outer peripheral portion 5 having a substantially triangular shape. However, the present invention is not particularly limited thereto. As shown in FIG. 10, the outer peripheral portion 5 can be circular, and the protruding portion 6 is not limited to a square shape, but can have a curved shape as shown in FIG. 10. It is. Accordingly, the cross-sectional shape of the chopstick H can be any shape.

Things.

Therefore, the chopstick tip side protruding member and the chopstick rear protruding member have a predetermined interval corresponding to the size of the hand in the front and rear directions of the lower chopsticks, and the protruding portions of the chopsticks are approximately 120 degrees. Since it is attached with a rotation angle, the outer side of the finger pad near the base of the thumb and the finger pad near the tip of the ring finger with respect to the protruding direction of each chopstick tip side protruding member and the chopstick rear side protruding member are approximately The contact can be made to be orthogonal.

Accordingly, the outer side of the finger pad near the base of the thumb and the finger pad near the tip of the ring finger are stably guided in contact with the rear end face and the tip face, so that the lower chopstick is stably gripped, The lower chopsticks can be kept constantly immobile.

The mounting positions of the chopstick tip-side protruding member and the chopstick rear-side protruding member are set at predetermined intervals in the front-rear direction of the lower chopsticks, for example, according to the size of the hand with respect to an infant, school child, adult, or the like. 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, so that the lower chopstick can be correctly held.

Further, in the present invention, by gripping the lower chopsticks as described above, the three fingertips of the upper chopstick, namely the thumb, the middle finger and the index finger, can be easily and naturally guided. This also sets the positional relationship between the three fingers, the thumb, the middle finger, and the index finger, and the upper chopstick, stabilizes the gripping state, and allows the upper chopstick to be freely operated with the index finger and the middle finger. As a result, it is possible to easily hold the correct chopsticks by learning how to hold the correct chopsticks.

On the other hand, this holding practice chopstick has a simple structure because the finger guide member composed of the chopstick tip side projecting member and the chopstick rear projecting member is simply attached to the lower chopstick. Therefore, there is little sense that the training tool is attached to the chopsticks, so that the training device can be easily used and the cost can be reduced.

The holding practice chopsticks of the invention according to claim 2 are:
As described above, in the holding practice chopstick according to claim 1, the predetermined distance between the chopstick tip-side protruding member and the chopstick rear-side protruding member is from the base of the thumb to the base of the index finger to the base of the middle finger. The distance is larger than half the distance between the base of the third finger and the base of the index finger, and is smaller than half the distance between the base of the thumb and the base of the index finger and the base of the palm.

Therefore, the size of the hands of infants, school children, adults and the like varies widely, but the predetermined distance between the chopstick tip-side protruding member and the chopstick rear-side protruding member attached in the front-to-rear direction of the lower chopsticks is set to this value. With this 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.

As a result, in addition to the effect of the invention according to the first aspect, there is an effect that the lower chopstick can be reliably held correctly regardless of age or gender.
