[Prior art]

As shown in Utility Application No. 55-108031, which was previously proposed by the inventor of the present invention, the conventional chopstick holding correction exercise tool consists of a spacer that is held between a pair of walls and an upper chopstick support groove and a lower chopstick support groove. A chopstick support part is formed, and a thumb-side belly contact part is provided on the side edge of the wall near the chopstick tip, and the upper chopstick support groove supports the upper chopsticks, and the lower chopstick support part supports the lower chopsticks. At the same time, the correct position of the lower thumb relative to the chopsticks is controlled by the thumb-side pad contact portion, thereby enabling the user to learn the correct way to hold the chopsticks.

However, in the structure in which the thumb-side belly contact part is provided on the side edge of the wall body closer to the chopstick tip, it is difficult to form a medicine finger fixing part that guides and regulates the ring finger, which is located closer to the chopstick tip than the thumb, to the correct position. Therefore, the above-mentioned
(b) It becomes difficult to control the correct position of the ring finger as in the second half. In addition, the position of the thumb side belly contact part is not necessarily clear, so the side thumb side should not be brought into contact with the side edge of the wall near the chopstick tip, but the side of the thumb should be brought into contact with other parts of the corrective exercise tool. There is a risk that the corrective exercise equipment may be used incorrectly. Furthermore, depending on the type of chopsticks, incompatibility may occur between the lower chopsticks and the lower chopstick support.
This causes the lower chopsticks to wobble, making it impossible to achieve the stable and immobile state of the lower chopsticks described in (c) above. In order to eliminate the above-mentioned non-conformity, it is necessary to prepare individual corrective training tools equipped with lower chopstick support parts that match the types of chopsticks, which is an economically disadvantageous problem. have

[Purpose of invention]

The present invention has been developed in consideration of the above-mentioned conventional problems, and it makes it easier to understand the correct way to use the corrective exercise tool, and makes it easier to learn the correct way to hold chopsticks. The purpose of this invention is to provide a training tool for correcting how to hold chopsticks, which can be used regardless of the type of chopsticks.

[Structure of the idea]

The chopstick holding correction training tool of the present invention has a spacer interposed between the upper and lower chopsticks that is clamped between a pair of walls, and the upper chopsticks that are surrounded by the top piece of the back surface of the wall and the upper end of the spacer. A support groove is formed, and a lower chopstick support groove is formed surrounded by the lower side of the back surface of the wall body and the lower end of the spacer, and a thumb side belly abutment piece is formed to protrude from one wall body on the side closer to the chopsticks. , a ring finger fixing part is formed on the side edge of the other wall closer to the tip of the chopsticks, and a removable lower chopstick fixing member is fitted between the walls forming the lower chopstick support groove, so that the thumb and ring finger can be fixed. The present invention is characterized in that it is configured so that the lower chopsticks can be kept in a stable and immovable state regardless of the type of chopsticks as well as correctly regulating their position.

[Embodiment 1] A first embodiment of the present invention will be described below based on FIGS. 1 to 4.

FIG. 1 is a perspective view of the corrective exercise tool 1 of this embodiment, in which a spacer 2 fitted between upper and lower chopsticks H ₁ and H ₂ is viewed from the front and back by a pair of substantially triangular walls 3. , 3', and a thumb-side belly abutting piece 7 is formed protruding from the wall 3 on the front side of the corrective exercise tool 1 near the chopsticks, and the chopsticks are held between the opposing walls 3, 3'. A lower chopstick fixing member 8 is fitted into the tip portion.

The spacer 2 that maintains a constant distance between the upper and lower chopsticks H ₁ and H ₂ is arranged so that its upper end is slightly below the upper ends of the walls 3 and 3', and its upper end surface 2a and the wall The upper chopsticks H1 are supported by the upper chopstick support grooves 4 formed by the upper pieces of the back surface of the upper chopsticks 3 and ₃ '. In addition, the lower end of the spacer 2 is
The lower chopstick support groove 5 formed by the lower end surface 2b of the spacer 2 and the lower back piece of the wall 3, 3' is positioned slightly above the lower end of the wall 3, 3'. It is configured to support the lower chopstick _H2 . Here, the upper end surface 2a of the spacer 2, which becomes the bottom surface of the upper chopstick support groove 4, is not parallel to the lower end surface 2b of the spacer 2 that supports the lower chopstick _H2 , and the chopstick is not parallel to the lower end surface 2a. A downward slope is given to the tip side.

On the surface of the wall 3 on the front side of the corrective exercise tool 1, on the side nearer to the chopsticks, a thumb side belly abutment piece 7 is formed to protrude perpendicularly to the wall 3. Thumb side belly contact piece 7
are arranged so that the lower end surface 2a of the spacer 2 is used as a reference plane, and the angle seen from the extended position on the chopstick tip side with respect to the reference plane is 60 to 80 degrees.

A lower chopstick fixing member 8 made of an elastic material such as rubber or plastic is removably fitted between the walls 3 and 3' of the chopstick tip end of the lower chopstick support groove 5, and a lower chopstick fixing member 8 is detachably fitted on the upper end surface 8a. Therefore, the lower chopstick H ₂ is pushed up toward the lower end surface 2b of the spacer 2, and the lower chopstick H ₂ is pushed into the lower chopstick support groove 5 by the upper end surface 8a of the lower chopstick fixing member 8 and the lower end surface 2b of the spacer 2. It is designed to be fixed in an immobile state. The chopstick tip side side 8b of the lower chopstick fixing member 8 is parallel to the chopstick tip side edges of the walls 3, 3', and its upper end surface 8a is parallel to the spacer 2.
They are each formed parallel to the lower end surface 2b of. The chopstick tip side edges of the wall bodies 3 and 3' and the chopstick tip side side surface 8b of the lower chopstick fixing member 8 form a chopstick tip side side surface of the corrective training tool 1, and the back surface of the correction training tool 1. A ring finger fixing portion 3'a for guiding and regulating the ring finger is formed on the side edge of the side wall body 3' closer to the chopstick tip.

3 and 4 show a state in which the above-mentioned corrective exercise tool 1 is used to hold the upper and lower chopsticks H ₁ and H ₂ . The entire corrective exercise device 1 is constructed of a wall 3′ on its back side.
The upper edge of the side of the chopsticks nearer to the proximal side is applied to the lower side of the index finger extending from the lower part of the second joint to the second joint, and the thumb side belly contact piece 7 provided on the wall 3 on the surface side is applied to the side of the index finger. The surface of the wall 3 on the side closer to the chopsticks is applied to the abdomen of the thumb, so that it is sandwiched between the thumb and forefinger. Further, a ring finger fixing part 3'a formed on the side surface of the corrective training tool 1 near the chopstick tip is applied to the upper side of the ring finger extending from slightly beyond the first joint to the fingertip. The spacer 2 is interposed between the upper and lower chopsticks H ₁ and H ₂ , thereby maintaining the proximal sides of the upper and lower chopsticks H ₁ and H ₂ at a predetermined distance. Here, the lower chopstick H ₂ is
Wall bodies 3, 3' at the tips of the lower chopstick support grooves 5 closer to the chopstick tips
It is pushed upward by the upper end surface 8a of the lower chopstick fixing member 8 fitted therebetween, and is immovably fixed to the lower chopstick support groove 5 along the lower end surface 2b of the spacer 2. In this state, by placing a portion of the upper chopstick along the flank or abdomen from the second joint of the index finger to the fingertip, and the flank near the first joint of the middle finger, each finger will naturally be in the correct position relative to the chopsticks. Positioned.

That is, a part of the lower chopstick H ₂ on the hand side is held between the base of the thumb and index finger, and a part on the chopstick tip side is supported by the first joint of the ring finger and the upper part of the side of the tip. This will satisfy the requirement (a) for the correct way to hold chopsticks. In particular, in the present invention, by providing the ring finger fixing portion 3'a, it becomes easier to regulate the correct position of the ring finger compared to the conventional example. Furthermore, lower chopsticks
As mentioned above, H ₂ is in an immovable state and cannot be moved by finger operation. This satisfies the above-mentioned requirement (c) of how to hold the chopsticks correctly, and in the present invention, the lower chopstick support groove 5 is fitted between the walls 3 and 3' at the tip of the chopsticks. By means of the lower chopstick fixing member 8, the wall body 3 of the lower chopstick support groove 5,
Since the lower chopstick _H2 can be fixed even if there is a mismatch between the lower chopstick H2 and the lower chopstick H2, the lower chopstick _H2 can be fixed.
H ₂ does not wobble and can achieve a more stable immobile state than conventional examples. Furthermore, this is true regardless of the type of chopsticks.

In addition, the thumb, whose position is regulated by the thumb-side belly contact piece 7, is set at an angle of 60 to 80 degrees with respect to the lower chopsticks _H2 when viewed from the chopstick tip side, which is the requirement for the correct way of holding chopsticks as described above. e). Moreover, as long as the thumb is placed along the thumb-side belly abutment piece 7, the abdomen from the first joint to the fingertip can be placed along the first joint of the index finger or the flank close to this. In addition to avoiding or correcting the incorrect way of holding chopsticks, such as when holding chopsticks H ₁ , the above-mentioned requirement (b) of the correct way of holding chopsticks (the part regarding the thumb) is met. Here, in the present invention, the abutment position of the thumb side belly is more clearly determined by the thumb side belly abutment piece 7 compared to the conventional example, so that the corrective exercise tool 1 may be used incorrectly. There is less risk, and the thumb can easily come into contact with the corrective exercise tool, so that the corrective exercise tool 1 can be held between the thumb and index finger more stably.

Upper chopstick H ₁ supported by upper chopstick support groove 4
As mentioned above, is held between the index finger and the middle finger, and is moved up and down using the end of the upper end surface 2a of the spacer 2 closer to the chopstick side as a fulcrum. Moreover, since the upper end surface 2a has a downward slope toward the chopstick tip side that does not restrict the movement of the upper chopstick _H1 , the degree of freedom of the index finger and middle finger is greatly guaranteed. . These things satisfy the requirements (b), (d), and (c) for the correct way to hold chopsticks mentioned earlier.

[Embodiment 2] Figures 5 to 7 show a second embodiment of the present invention, in which the walls 3, 3' of the tip of the lower chopstick support groove 5 supporting the lower chopstick _H2 are disposed toward the tip of the chopstick. Projections 5a, 5a are formed on the back surface substantially parallel to the lower edge thereof. As shown in FIG. 7, the protrusions 5a, 5a are sloped so that the interval between the inner ends of the protrusions 5a, 5a narrows as it goes from the tip closer to the tip of the chopsticks to the side closer to the chopsticks. There is.

_The lower chopstick fixing member 8 is moved in the direction shown by the _arrow in FIG. It will be done. here,
The lower chopstick fixing member 8 is fixed to the lower chopstick support groove 5, and the lower chopsticks _H2 are fixed to the lower chopstick support groove 5 by the protrusions formed on the back surfaces of the walls 3, 3'. can be made stronger than in the first embodiment shown above. Other configurations are the first
This is the same as in the embodiment, and the same members are given the same reference numerals.

[Effect of idea]

The present invention has the above-described configuration, and the following effects can be obtained.

(a) The correct position of each finger relative to the chopsticks is regulated, and the lower chopsticks are held in an immovable state by the lower chopstick support groove and the lower chopstick support member fitted therein, so the correct way to hold the chopsticks is correct. can be acquired in a short period of time. In particular, by providing the thumb side belly contact piece and ring finger fixing part in the embodiment, the above-mentioned learning can be accomplished more easily and in a shorter period of time.

(b) The thumb side belly contact piece restricts the thumb to be at an appropriate angle with respect to the chopsticks, so the thumb can be placed along the first joint of the index finger or the flank close to this, and the thumb If you hold the upper chopsticks with only your index fingers, you can avoid or correct the incorrect way you hold the chopsticks.

(c) Due to the lower chopstick fixing member fitted between the walls forming the lower chopstick support groove, even if there is wobbling due to misfit of the lower chopsticks in the lower chopstick support groove,
The lower chopsticks can be kept in a stable and immobile state. Therefore, one corrective training tool can be used for various types of chopsticks, which is economically advantageous. In addition, since the lower chopstick fixing member is detachable between the walls, the lower chopstick fixing member can be removed when cleaning the corrective exercise equipment, so the lower chopstick support groove can be cleaned. It is easy and convenient to maintain hygiene.

(d) The protrusion formed on the back surface of the wall of the lower chopstick support groove makes the fixation of the lower chopstick support member in the lower chopstick support groove, and ultimately the fixation of the lower chopsticks in the lower chopstick support groove, even stronger. As a result, a more stable and immobile state of the lower chopsticks can be realized, and as a result, it becomes easier to learn how to hold the chopsticks correctly.
