Description

  The present invention relates to a small writing instrument that can be written in a state of being pinched only by a fingertip.

  Conventionally, a stick-shaped writing instrument widely used, a writing instrument wrapped in the palm of a hand, and a writing instrument attached to a fingertip are known. Bar-shaped writing instruments are known for everyday use, such as pencils and ballpoint pens. Examples of writing instruments that are wrapped in the palm of the hand are disclosed in Japanese Unexamined Patent Application Publication No. 2011-25509 and Japanese Unexamined Patent Application Publication No. 2011-154274. Examples of writing instruments to be attached to the fingertips are those disclosed in JP-A-11-245582 and JP-A-63-127881.

  A stick-shaped writing instrument can have various functions and decorations, but because it is stick-shaped, it holds the top of the writing instrument with a finger and supports the middle of the shaft with the base of the index finger and thumb Therefore, there is a problem that a certain length and thickness are required, and it cannot be extremely miniaturized. A writing instrument wrapped in the palm of the hand is not supported by a finger, so there is an advantage that writing can be done by just grasping, but there is a problem that a certain size is required like a stick-shaped writing instrument. Although the writing instrument attached to the fingertip is small, there is a problem that it is troublesome to attach to the fingertip and there is a feeling of pressure on the finger even if the finger can be attached.

  An object of the present invention is to provide a small-sized writing instrument with improved portability that allows writing while being supported only by a fingertip.

  In order to solve the above problems, the writing instrument of the present invention comprises a writing body, a plate-like support portion sandwiched between the thumb and forefinger, and a plate-like blade portion sandwiched between the support finger and the index finger and the middle finger, The support part and the blade part are formed in a V shape to form a support body, and are attached by bending the writing body to the side of the support part along the connection of the support part and the blade part. It is desirable to fold the support part and the blade part by connecting the support part and the blade part with a tiltable structure such as a hinge.

  According to the writing instrument of the present invention, it becomes a small writing instrument that is a size that can be supported only by the thumb, the index finger, and the middle finger, and the portability can be improved. In addition, since writing is performed while being supported by the fingertip, there is no troublesome attachment to the fingertip, and writing can be performed without feeling pressure on the finger.

It is a perspective view of the writing instrument which concerns on this invention. FIG. 2 is an exploded view of FIG. 1. FIG. 3 is an exploded view of FIG. 2. It is a figure explaining the use condition of a writing instrument.

Hereinafter, embodiments of the writing instrument according to the present invention will be described with reference to FIGS.
The writing instrument 1 includes a support body 2 and a writing body 5, and the support body 2 includes a support part 3 and a blade part 4, and the support part 3 and the blade part 4 form a substantially triangular shape.

  The length of the side 3a and the side 4a is about the length of the first joint of the index finger (2 cm to 3 cm, preferably 2.5 cm) so that writing is supported only by the fingertip. The thickness of the support part 3 is such that it does not exceed the thickness of the cursive body 5 (3 mm) in order to reduce the level difference between the support part 3 and the cursive body 5 so that there is no sense of incongruity when supporting with a finger. is there. The blade portion 4 has a thickness (1 mm to 2 mm, preferably 1 mm) that does not cause a sense of incongruity when sandwiched between the index finger and the middle finger.

  The side 3b is a part along the axis 5b of the cursive body 5. Although it may be constituted by a straight line, it is preferably a curved line in order to follow the axis 5b.

  Reference numerals 3 d and 3 e are fitting holes provided in the support portion 3. 4b is a fitting hole provided in the blade portion 4, and constitutes a hinge together with the fitting hole 3d and the fitting hole 3e. The inner diameters of the fitting holes 3d, 3e, and 4b are slightly larger than 3 mm so that the writing body 5 can be inserted smoothly.

  The shaft 5b of the cursive body 5 is a flexible material that can be bent such as plastic resin. The length of the cursive body 5 is a length (6 cm to 9 cm, preferably about 6 cm) that does not exceed the length of the entire circumference of the side of the support portion 3 (the total length of 3a, 3b, and 3c). It is.

  The side 3a and the side 4a are aligned so that the support part 3 and the blade part 4 are line symmetric with respect to the side 3a and the side 4a, the fitting holes 3d, 4b, and 3e are aligned, and the tip 5a of the writing body 5 is aligned. Are inserted in the order of the fitting holes 3e, 4b, and 3d, and the writing tip 5a protrudes from the fitting hole 3d by about 5 mm.

  The shaft 5b of the cursive body 5 is bent along the side 3b of the support portion 3 and reaches a fastener 3f described later.

  The fastener 3f is provided in the support part 3 and fastens the terminal end 5c of the cursive body 5. The fastener 3f has a cylindrical shape that is not closed, and can be attached and detached so that the terminal end 5c of the cursive body 5 is hidden from the open portion of the cylinder.

  With reference to FIG. 4, how to handle the writing instrument 1 will be described. The writing instrument 1 is supported in a state where the support part 3 is sandwiched between the thumb and forefinger and the blade part 4 is sandwiched between the index finger and the middle finger, and writing is performed at the writing tip 5a. At the time of storage, the support part 3 and the blade part 4 are folded to be in a more miniaturized state.

  The material of the support part 3 and the blade | wing part 4 has a rigidity which can fix the writing body 5, such as a metal, a plastic resin, a timber, and rubber | gum.

  The shaft 5b is preferably a plastic resin that can be bent. However, the shaft 5b may be a rigid body such as a metal as long as the length of the writing body 5 is within the length of the side 3a.

Claims (2)

  It consists of a cursive body and a support body that is formed in a V shape by connecting the support portion and the wing portion and attaches the cursive body. The cursive body is attached along the edge of the support body, and the support body is sandwiched between fingers. Writing instrument characterized by doing.   The writing instrument according to claim 1, wherein the support part and the blade part can be folded.
