Description

  The present invention relates to a writing posture correction device, and more particularly, to a writing posture correction device provided to a user for learning an accurate writing posture so that pain and injury caused by wrong writing are eliminated.

  Usually, writing instruments such as ballpoint pens, pencils, fountain pens, sign pens, marker pens, needle pens, needle pens, water pens and drawing pens are circular brush tubes, and these Because of the small arc of the writing instrument's writing tube, if a general person writes too much power over a long period of time, a deep dent will remain at the joint at the end of the middle finger, and the middle finger and thumb will be able to tap. . In addition, since the user puts too much force on the finger so that the thin and round writing tube of these writing tools does not move backward by writing, the index finger receives pressure and is distorted and deformed.

  A child's writing moment is said to be the beginning of all learning, so an accurate writing posture is especially important for children. However, such basic construction work is often ignored, so most people get used to the wrong writing attitude and writing habits from a young age.

  These inaccurate methods are, for example, as shown in FIGS. 1A and 1B, where the palm is not hollow and the joint becomes right-angled due to incorrect operation or excessive tension of the fingers, or with a pencil at the fingertip. And will put too much effort into writing. In this way, writers (especially children) are overwhelmed, feel pain when writing, muscles and skeletons are more likely to get tired, and can cause injury, and aversion to writing homework. This has a huge impact on the learning process.

  In order to solve the above problem, a writing practice device 10 is known as shown in FIGS. 2A and 2B. The writing practice device 10 is provided with an arc-shaped concave tank 10a for gripping with fingers and a pad 10b disposed in the concave tank 10a. The pad 10b is formed with a notch 10c for accommodating the writing instrument 100. However, although the writing practice device 10 contains five fingers in the concave tank 10a, the middle finger, ring finger, and little finger grip the concave tank 10a toward the writing direction, so the middle finger, ring finger, and little finger are tightly held in the palm of the hand. May be in the wrong posture.

  Traditionally, the point of writing is in the “false hand and fingers”, and the principle that the writing should follow is “There is no fixed law, it is imaginary and cheap”. Cannot correct the wrong writing posture and feels fatigue and discomfort in the hands. At the same time, as shown in Fig. 2B, the writing practice device 10 incorporates an accurate writing posture in which the fingers are housed in the recessed tank 10a, but the user's index finger supports the writing tube at an angle of approximately 90 degrees. Therefore, the user's index finger is not only deformed by pressure, but children who have just started to practice writing feel resistance to writing due to overwriting.

  In order to solve the above-mentioned problem of the writing practice device 10, Taiwan Utility Model Notification No. 314836 proposes a training device 20 for assisting writing. As shown in FIGS. 3A and 3B, the training device 20 mainly includes a brush fitting tube 21 and two penetration tubes 22 and 23. The brush fitting tube 21 is hollow and pierces the writing tube of the writing instrument 100. Used to enter. The two penetration cylinders 22 and 23 are used for penetration and positioning of the third finger portion of the index finger and the middle finger. The third finger part is the first finger part from the phalanx connected to the palm according to the order from the base of the finger (that is, the part connected to the palm part), and the second finger part is the next. It is. In general, the thumb has two fingers, but the other fingers naturally have three fingers.

  The training device 20 is provided with a notch 23a for supporting the writing tube by bending the middle finger at a middle position of the penetrating tube 22 and the penetrating tube 23 having a bending angle for penetrating the middle finger. However, because the size and thinness of the fingers and joints differ depending on different users, if the two penetration cylinders 22 and 23 are too small, the fingers and joints may be caught, making it difficult to penetrate or remove them. Can no longer penetrate. Therefore, if the two penetrating cylinders 22 and 23 are too small, it becomes impossible to determine and hold the positioning of the fingers, and writing becomes difficult.

  In addition, as shown in FIG. 3B, such a training device 20 is used to position the index finger and middle finger, thus ensuring an accurate writing posture for positioning the other fingers holding the `` imaginary palm ''. If the training device 20 is applied, the user must hold his / her finger due to a mistake in operation because the user cannot support the writing tube with his / her thumb tip and pinches the part away from the writing tip of the writing instrument 100. If you hold your palm tightly, excessive joint tension or fingertips may be too supportive for the brush tube, and you may not be able to relax your finger muscles and skeleton and become tired.

  In order to solve the above-mentioned drawbacks of the conventional apparatus, a writing practice device 30 is proposed in Taiwan Utility Model Notification No. 454705. As shown in FIG. 4A, the writing practice device 30 has a hollow columnar shape, and is provided with openings 31 on both sides for penetrating the writing tube to which the writing tool 100 is connected. On the surface of the writing practice device 30, there are provided a positioning point 32 and a position shift body 33 for finger positioning and position shifting.

  However, such a writing practice device 30 can only position three fingers, such as the thumb, index finger, and middle finger, and cannot maintain the correct posture of the ring finger and little finger muscles and skeleton, and when writing, it is shown in FIG. As shown, the ring finger and little finger are firmly held in the palm of the hand, which is a burden of force. Therefore, when such a writing practice device 30 is applied, the user cannot relax the muscles and the skeleton and is easily fatigued, and thus cannot solve the drawbacks of the conventional technology.

  In addition, although the writing practice device 30 is used only for positioning the finger, the positioning point 32 does not have an ergonomic writing structure, so that the finger touching the positioning point 32 is painless after a certain writing time. Will feel. Further, since the hollow portion of the writing practice device 30 can only accommodate a writing tool of a specific size, it cannot be applied to a writing tool of a different size, and the labor for replacement increases when using a different writing tool.

  Moreover, when the writing practice device 30 is integrally formed with the writing instrument 100, the writing practice device 30 has three position shift bodies 33 that open in a wing shape, so that it is difficult to accommodate in the container and is portable. For example, it is inconvenient to store it in a pocket of a jacket. Therefore, such a writing practice device 30 cannot accurately provide the user with correction of the writing posture, and the appearance of the writing instrument is not beautiful, and there are various disadvantages such as storage and form defects.

  In addition, the above-mentioned conventional technology cannot issue a warning even if the user writes in the wrong posture, so if the user is not writing in the correct posture, it will be used even if there is a position to position the finger. It is impossible to correct whether a person's fingering is wrong, overpowered, or writing in another wrong posture. Therefore, the user cannot learn an accurate writing posture.

  Therefore, in order to solve the above-mentioned various disadvantages of the prior art, the user can write “false hand real finger” by correcting the writing posture and providing a writing posture correcting device considering different age, sex and usage habits. It is extremely important to understand the point and to have fun learning with accurate, easy, and comfortable handwriting functions.

  In view of the above problems, an object of the present invention is to provide a user with a writing posture calibration device for avoiding pain and injury caused by wrong writing and for accurately learning the writing posture.

  Another object of the present invention is to provide a user with a writing posture correction device that has a detection function and can issue a warning so that an error in writing posture or excessive force can be improved. .

  Another object of the present invention is to provide a user with a writing posture correction device having a detection function in order to avoid excessive force during writing by accurate writing and grasp an appropriate force.

  In order to achieve the above object, the writing posture correction device according to the present invention provides the user with a writing posture correction device for avoiding pain and injury caused by wrong writing and for accurately learning the writing posture. For the purpose. One of the preferred embodiments of the writing posture correcting device of the present invention is a main body for a user to hold in the palm of the hand, an abutting portion formed on the top of the main body and abutting on the user's tiger mouth, A first positioning part formed on one side of the main body for positioning the user's thumb; a second positioning part formed on another side of the main body for positioning the writing instrument; and Formed on one side of the second positioning portion away from the main body, between the third positioning portion for positioning the middle finger of the user, and between the second positioning portion and the third positioning portion A fourth positioning part for positioning the index finger of the user, and one side away from the second positioning part of the third positioning part, the user's ring finger and little finger It is characterized by comprising a grip part for naturally curving That.

  Using the first positioning unit, the second positioning unit, and the fourth positioning unit, the force points of the user's thumb, middle finger, and index finger are combined, and the user's ring finger and little finger are attached after the middle finger. Therefore, when the user's finger can correct the writing posture with the writing posture correcting device of the present invention and grips the writing instrument, the finger does not naturally curve and touch the palm, and the palm is held in a hollow state. Become.
