Description

{TWIST COLOR CRAYON}

The present invention relates to a sharp-type color pencil which can be drawn out, and more particularly, to a color pencil in which a color is rotated in the colored pencil main body only by rotating the color- And after the use of the colored pencil is rotated, the user rotates the turning cap knob of the colored pencil in the other direction, It is about possible Sharp color pencils.

In general, crayons, colored pencils, and solid shape markers are known as solid shape drawing bodies for expressing colors on handwriting surfaces such as paper or whiteboards by hand while drawing or writing. Colored pencils among solid shapes are easy to handle and are relatively thin, so that they are easy to express delicate parts when drawing, and are also widely used for children because they are convenient to use as writing instruments. The colored pencil is composed of a core member for drawing or writing, and a color pencil main body which is provided so as to surround the outside of the core member except for the tip end, and to be hand held when used.

The colored pencil thus formed is worn away as the drawing or writing is performed, so that the length of the front end portion exposed from the colored pencil body gradually becomes shorter, so that the length of the front end portion is shortened so that the length of the colored pencil body is also shortened. There is a problem that it is troublesome to carry out and it is always inconvenient to store and carry with the tip exposed.

In order to solve such a problem, Korean Utility Model Registration No. 261375 discloses a color image forming apparatus in which a predetermined color is formed by solidifying a predetermined pigment into a bar shape and a male thread of a predetermined pitch is formed on a circumferential surface of a semicircular shape, Wherein the male thread member for pulling out the color core and the male screw member from the inside and the female screw member for pulling out the color core are in contact with each other along the axial direction with one side edge of the thread of the male screw at the time of relative rotation, Wherein the coloring member is relatively rotatably coupled to one side of the casing so as to be rotatable relative to the color-threaded screw member to relatively rotate the male screw member with respect to the female screw member, And the color-correcting member is rotated by the color- It proposed the drawing take-off and formed to be withdrawn to the structure to boost the group color depth on one side.

However, in the case of using the proposed color pencil, the color pencil is gripped and painted by one hand of the user, and the color driving member is rotated with the other hand of the user in order to supplement the missing color as much as the used amount The two hands of the user are not free and the usability is very uncomfortable, and the color driving member for drawing out and withdrawing color depth is undesirably rotated by any external impact, so that the color depth inherent in the conventional color pencil is undesirably withdrawn And the problem of being broken still remains.

In order to solve such a problem, Korean Utility Model Publication No. 2014-0000802 discloses a colored pencil body in which a prescribed color colored deep-colored material is embedded and an open part is formed at one end thereof so that the deep colored material can be taken out; A rotary exit for rotating and conveying the shim member within the colored pencil body; And a rotating means which is connected to one end of the colored pencil and which rotates the rotary outlet. The rotary member formed at one end of the colored pencil body allows the user to draw the shim during use of the colored pencil, In this paper, we propose a rotary drawing color pencil which can prevent free rotation that is not desired by the user when a colored pencil is used by forming a stop groove and a stopping projection. However, unlike the operation principle of a sharp pencil used by a user, When the wear and tear is worn out, the ball comfort that the user has to rotate the rotary exit to withdraw the shim member still remains, and the problem that the shim member is inconvenient to replace the shim member still remains when the shim member is exhausted.
