SOLUTION: A grip for a writing instrument to be fitted into a square-shaped writing instrument, from a contact portion in contact with a chevron portion of the writing instrument inside a cylindrical elastic body, and an outer shape of the chevron portion of the writing instrument extending behind the contact portion. A large non-contact portion was provided. [Selection diagram] Fig. 1

Description

The present invention relates to a movable grip that is attached to the outer circumference of a writing instrument.

Traditionally, pencils have many hexagons and are thin and hard, so they require strength to write letters, and children in the lower grades of elementary school mainly use 4B pencils that can write deeply without any effort. Even so, if you use it for a long time, you may get tired, and the corners of the pencil may hit your fingers, causing imprints or pain on your fingers. Use a round pencil to avoid it, but it has the problem of slipperiness.

Prior art

Conventionally, a fixed grip that is easy to hold with mechanical pencils, ballpoint pens, etc., and does not get tired even after long-term use has been installed.

For example, a hexagonal pencil is thin and hard, so if you do not hold it firmly, it will be slippery, and if you use it for a long time, the hexagonal corners of the pencil will be imprinted on your finger and you will get tired easily. Some people hold it irregularly to avoid it. Therefore, the subject of the present invention is that it can be easily fitted into a writing tool such as a square pencil, the tip can be cut as necessary to reduce the holding force, and the grip can be gripped when the core is broken or reduced. The purpose is to provide a stationery grip that allows the pencil to be easily moved and sharpened.

In order to solve the above problem, the grip for a writing instrument according to claim 1 is larger than the outer shape of the contact portion in contact with the chevron portion of the writing instrument inside the cylindrical elastic body and the chevron portion of the writing instrument adjacent to the contact portion. It is characterized in that a non-contact portion is provided, the grip can be held by the contact portion, and the contact portion can be cut as necessary to reduce the holding force. It is also possible to shorten the total length of the grip so that only the contact part is shaped.

The writing tool grip according to claim 2 is characterized in that it can be held by a round writing tool by providing a plurality of protruding portions inside a cylindrical elastic body.

The grip for a writing instrument according to the invention of claim 1 can be easily fitted into a writing instrument, and if necessary, the tip is cut to reduce the frictional force, the holding force and the moving force can be adjusted, and even if writing is performed for a long time. It is hard to get tired and there are no imprints on the fingers. In addition, the outer shape can be made into a shape that is easy to grip, for example, a shape such as a triangle, and the correct way of holding can be forcibly corrected.

The grip for a writing instrument according to the invention of claim 2 can be attached to a round pencil by providing a plurality of protruding portions inside.

It is a figure which shows the embodiment of one Example of this invention, and shows the state of the writing tool grip attached to the hexagonal pencil as a writing tool, for example. FIG. 1 is an enlarged view of A view from the front direction in the axial direction of a pencil equipped with a grip for writing tools of the embodiment shown in FIG. 1, and FIG. 1 (b) shows an enlarged view of B view from the rear in the axial direction. It is sectional drawing which shows the modification of the grip for a writing instrument of this invention shown in FIG. It is sectional drawing which shows the other embodiment which attached the grip which provided the protruding part inside.

The writing tool grip according to the present invention shown in FIG. 1 has a shape having a contact portion L1 which corresponds to a chevron portion of a pencil and a non-contact portion L2 which is adjacent to the contact portion L1 and does not come into contact with the pencil. It has a holding force and is configured to be movable in the axial direction. Further, by cutting a part of the grip 1 in the direction of the tip of the pencil, the strength of the holding force of the grip can be adjusted.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows an axial cross-sectional view in which the writing tool grip 1 of the present invention is attached to, for example, a hexagonal pencil 2. The writing tool grip 1 according to the present invention is formed of an elastic body such as rubber or resin in a cylindrical shape. When using the writing tool grip 1, the grip 1 is fitted from the front of the pencil 2 and used.

FIG. 2 shows an axial cross-sectional view of the writing tool grip 1 fitted in the pencil 2. In the figure, L1 is a contact portion that contacts the chevron portion of the pencil 2, and L2 is a non-contact portion that does not contact the chevron portion of the pencil 2 that extends behind the contact portion L1 and has a shape that is easy to fit when attached to the pencil. It is being struck by. That is, the writing tool grip 1 is formed so as to have a taper over the entire length L and toward the rear portion of the pencil 1.

By making the inner diameter of the contact portion L1 slightly smaller than the outer diameter of the chevron of the pencil 2, a frictional force is generated between the chevron portion of the pencil 1 and the contact portion L1 of the writing instrument holding grip so that the contact portion L1 can be held on the pencil. The grip 1 can be moved by applying a force in the axial direction of the pencil. It does not move with a weak force when writing.

When adjusting the holding force of the writing tool holding grip 1, the grip tip portion can be used by cutting an appropriate width, for example, about 1 mm with scissors or the like. If the holding force is too strong and it is difficult to move, the cut width may be increased.

In FIG. 2, (a) is an enlarged view of a pencil equipped with the grip for a writing tool of the present invention as viewed from the A direction, and (b) is an enlarged view as viewed from the B direction.

FIG. 3 is an axial sectional view showing a modified example of the writing tool grip shown in FIG. 1. It is a figure which shows the example which shortened the length of the total length L shown in the Example of FIG. 1, eliminated the non-contact part L2 part, and attached only the contact part L1 to a pencil 2.

In the above-described embodiment, an example of application to a hexagonal pencil has been shown, but it goes without saying that the application is not limited to a hexagon, but can be applied to a pencil having a triangle, a square, a pentagon, or more.

FIG. 4 is a diagram showing a modified example of the writing tool grip 4 of the present invention attached to the round pencil 6. In the figure, reference numeral 5 denotes a plurality of protruding portions provided inside the cylindrical writing tool grip 4. The inner diameter of the protruding portion 5 is made slightly smaller than the diameter of the round pencil 6 so that it can be held on the surface of the round pencil 6 and can be moved on the pencil 6 by applying an axial force.

The number of the projecting portions 5 may be any number of 3 or more. Further, the protruding portion 5 may be formed over the entire length inside the writing tool grip 4, or may be formed only on a portion of the writing tool 4 held by the user's fingertips.

Claims (2)

The grip for a writing instrument according to claim 1 is provided with a contact portion in contact with a chevron portion of the writing instrument and a non-contact portion adjacent to the contact portion and larger than the outer shape of the chevron shape of the writing instrument on the inside of a cylindrical elastic body for writing. It is characterized in that it can sometimes hold the grip and further cut the contact portion as needed to reduce the holding force. It is also possible to shorten the total length of the grip so that only the contact part is shaped. The grip for a writing tool according to claim 2 is characterized in that a plurality of protruding portions are provided inside a cylindrical elastic body.
