Definitions

• the present invention relates to a writing instrument.
• a writing instrument has a bar-shaped body portion, an ink container positioned in the body and a tip mounted to the container so that writing on a paper with ink flown out from the tip becomes possible.
• Such writing instruments can be classified, according to function thereof, into various types such as a fountain pen, a boll-point pen, a pencil, a sharp pencil, a magic pen, a name pen etc. and most thereof have a body portion with a bar or stick shape whose cross section is a circle, a square, a octagon or a triangle.
• the conventional writing instrument comprises a bar-shaped body portion 1, a tip 3 and a cap 2 fixed to an upper end or a lower end of the body portion 1 for protecting the tip 3.
• a tip holder 4 is screw- coupled to the lower end of the body portion 1 and a finger holder 5 made up of a soft and elastic material is used to reduce a sense of oppression and a load when a user grasps the writing instrument. Since the finger holder 5 is made up of the soft and elastic material and fixed to the lower end portion of the body portion 1, the index finger, the thumb and the middle finger of a user are prevented from directly becoming in contact with a hard surface of the body portion 1 to provide the user with a comfortable grip sense.
• the finger holder 5 since the finger holder 5 has a streamlined shape corresponding to the shape of fingers of a normal adult and in addition, may have a slow-curved square or triangle as needed, it serves for reducing a load imposed on the fingers in grasping it for a long time.
• the user having grasped the conventional stick-shaped writing instrument diagonally with the thumb and the index finger is supposed to exert force on the ends of the thumb and the index finger for writing with the writing instrument supported by a first knuckle of the middle fmger.
• the stick-shaped body portion is pushed by the tips of the thumb and the middle finger, there is a problem that the writing cannot be continued for a long time in a comfortable state.
• the conventional writing instrument has a relative small contact area, there is a problem that it provides users having a bad writing ability such as a baby, a student, an old man and a disabled person with inconvenience.
• An object of the present invention is to provide a V-shaped writing instrument in which natural intimacy can be induced from a streamlined shape thereof like a body and wings of a bird, a sense of oppression of the index finger can be released, a hardened skin can be prevented from being formed on the middle finger through increase in the contact area of the middle finger and a writing work can be performed in a comfortable grip state.
• a writing instrument comprising: a tip holder in which a penetration opening is formed at one end to protrude outward a tip of a core containing a writing material and a hollow inserting portion is formed at the other end; and a main frame having at least two wing portions at one end and coupling with the tip holder, for receiving the core, is provided.
• the writing instrument can further comprise a finger holder which is fixed between the two wing portions and constitutes wing portions having a shape corresponding to the shape of the two wing portions.
• the two wing portions are asymmetrical.
• a cap fixing portion is formed at the other end of said main frame, and a cap for protecting the tip of the core is coupled to the cap fixing portion. More preferably, the cap fixing portion is protrusion-shaped eccentric toward the lower-left side from one side end of the main frame and the cap is formed eccentric toward the lower-left side from the center thereof.
• a receiving groove extending to a lower surface through a space between the two wing portions is formed on an upper surface of said main frame, and the finger holder is coupled to the main frame, correspondingly to the receiving groove.
• the finger holder comprises a middle-finger-shaped portion, a lower support portion and a wave-shaped portion formed on both sides of the finger holder to be closely coupled to the receiving groove.

• the main frame 40 has an elegant and modern design as a whole together with both wing portions 41a, 41b, 51a, 51b and has a dynamic shape capable of providing the lower surface and the respective side surfaces of the thumb and the middle finger with a relatively large contact area.
• the finger holder 50 having a shape conesponding to the streamlined shape of the main frame 40 includes the index finger shape portion 54 and the wave shape portions 52, 53 formed along both axes conespondingly to the receiving groove 48, and as a result, this writing instrument is designed as a high-tech product capable of supporting the index finger comfortably and adding a comfort due to a smooth curve. Furthermore, when the finger holder 50 is coupled to the main frame 40, the thicknesses in the width direction of the left wing portions 41b, 51b conesponds to the gap between the index finger and the middle finger and are usually very thin. On the contrary, the right wing portions 41a, 51a are a little thicker than the left wing portions 41b, 51b. As shown in FIG.
