Description

DEVICE FOR THE CORRECT GRIPPING OF WRITING TOOLS TECHNICAL FIELD The present invention relates to a device for correct grip of writing tools and, more particularly, to a device for correct grip of writing tools having an ergonomically curved body and seating portions formed on specific parts of the body. for the seat of the thumb, the forefinger and the greater finger of the user in a preferential posture, which thus naturally corrects the grip posture while allowing to grip the writing tool.

Background art Incorrect grip of a writing tool causes deformation of the user's fingers, particularly of children, and fatigue the fingers, wrist, shoulders and other parts of the user's body. In more detail, the correct and preferable grasping posture is that a predetermined spatial part is formed between the thumb and the index finger when both fingers of the user take the writing tool (see FIG 11). At this time, since excessive force is applied to the portions of meridian points of the fingertips if the user grasps the writing tool for a prolonged period, the thumb and index finger gradually enter into close contact with each other. and therefore, the volume of the spatial part formed between those fingers is gradually reduced (see Fig. 12). This incorrect grip position is one of the main causes of finger deformity and it is therefore necessary to have a writing tool that provides a natural and effective grip position, able to maintain a correct grip condition even when the user Use the tool for a long time.

Disclosure of the Invention Accordingly, the present invention will be made in view of the problems expressed above and the object thereof is to provide a device for correct grip of writing tools, including seats for the thumb and index curved thereof shape that the spatial portion formed between the thumb and forefinger, as well as a seat for the greater that extends to a part where the writing tool and the major finger come into contact with each other, from the front and bottom portion of the seats of thumb and forefinger in order to support a portion of the greater finger and thus prevent there being close contact between the thumb and index finger when separating them. Another object of the present invention is to provide a device for correct grip of writing tools, which also includes a thumb support part formed in the lower part of the seating part thereof and supporting the thumb, through holes formed in the seats of the thumb and forefinger to absorb perspiration, as well as carved portions for pressure and prevention of the sliding of the fingers, thus allowing the user to use it more safely and pleasantly.

To achieve the foregoing objectives, the present invention provides a device for correct grip of writing tools that includes: a body with a curved surface; a part that avoids the contact of the thumb and another that avoids the contact of the curved index on the upper surface of the body in the same way as the space formed between the thumb and index of the user when he takes the writing tool with these fingers, so as to avoid a close contact of the thumb and forefinger with the tool, the parts preventing the contact of the thumb and index finger in contact with the upper surface of the body; a part of the thumb seat formed on the surface of the side wall of the lower portion of the part that avoids contact with the thumb, for the settlement of the thumb therein; a part of the index seat formed on the surface of the side wall of the lower portion of the part that avoids contact with the index, for the settlement of the index therein; a part of the seat of the greater finger that extends in descending form from the anterior and inferior portion of the body to a portion in which the writing tool and the user's major finger are in contact with each other, to support a part of the greater finger; as well as a coupling part for fixing the writing tool to the body at a predetermined angle. It is preferable that the device for correct grip of writing tools additionally includes a thumb supporting part that extends from the supporting part of the major finger to support the thumb.
