Description

Corrective apparatus for writing posture}

The present invention relates to a writing posture correcting mechanism for acquiring and correcting a correct posture of a finger holding a writing instrument.

Writing postures are difficult to fix for a lifetime once they get into habit. However, a bad writing posture can quickly exhaust the use of writing instruments and can lead to finger deformities, so it is very important to acquire the correct writing posture from the beginning.

To this end, various types of writing posture correctors have been applied and produced. However, most of the pre-applied and conventionally produced orthodontic instruments form a groove or jaw at a contact point of a finger which is located when the writing instrument is correctly grasped at a handle portion of the writing instrument, or such a groove or jaw is formed in the writing instrument. In many cases, assembling a detachable orthodontic mechanism to induce a writing instrument user to grab a finger in the groove or jaw so that the writing posture is corrected.

Further, in general, the latter method of attaching or detaching a separate fixing device to the writing instrument is industrially advantageous, rather than the former method of directly forming a groove or jaw directly in the writing instrument itself, and thus is widely used.

However, in the case of such a conventional method, the size of the calibration mechanism is not large, and the method of directly inserting or detaching the pencil into a pencil is not very widely used.

Thus, the tubular tools having a predetermined length to directly insert a portion of the writing instruments in addition to the calibration mechanism are further included, thereby making the utilization of the calibration mechanism more advantageous. However, writing instruments, such as pencils, whose length can only be reduced according to their use, must be inserted and reinserted with the tool according to their usage, and the writing instrument must be separated from the tool in order to reshape the core of the writing instrument. Therefore, the hassle of frequent detachment and detachment of the combination between the writing instrument and the corrective device, which is a conventional problem, still remains unresolved.

On the other hand, in addition to the above-described conventional embodiment, the handle may be a ring type formed so as to correctly guide the writing posture while the finger used for writing is fixed.

Therefore, the present invention has been devised to solve the above problems, and even if a writing instrument whose length varies according to the amount of use, such as a pencil, is used for the instrument for correcting the writing posture, there is no need to repeat the insertion and insertion of the writing instrument during use. It is an object of the present invention to provide a writing posture correcting mechanism that enables a more efficient writing posture correction by greatly reducing inconvenience in use caused by a shortening of a writing instrument.
