Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a writing implement made of a soft elastic material and having a shaft hole, which is removably covered on a shaft of a ballpoint pen, a mechanical pencil, an electronic pen or other writing implement or a sleeve of a core body (hereinafter referred to as a pen body). More specifically, the grip coverings for a plurality of writing implements are formed by gradually changing the gripping diameter of each of the plurality of grip coverings, and each of them can be selectively used according to the writing mode including the finger length and the writing pressure. The present invention relates to a set of different diameters of a grip covering for a writing instrument, which is a set of accessories or supplies that can be used and replaced. Here, the grip diameter is the grip diameter (outer diameter) at the time of mounting, and the covering means the covering mounting.

[0002]

[Prior art]

 Conventionally, ballpoint pens, mechanical pencils, electronic pens and other writing instruments have a shaft diameter of approximately 7 to 8 mm, and their cross-sectional shapes are often circular or polygonal.

[0003] In recent years, a relatively soft material has been applied to the grip portion of the finger to hit the finger to increase the friction coefficient and absorb the grip pressure, thereby assisting the maintenance of the writing pressure and supporting the muscle load. Some are trying to reduce (fatigue).

Under these circumstances, from the knowledge that it is effective to reduce the grip pressure by increasing the grip diameter (grip diameter), a so-called thick-axis writing instrument (hereinafter, thick-axis pen) has been proposed. And can be easily seen at stationery stores. Again, many grips have a covering attached (covered).

[0005] The inventor has made several proposals for a suitable covering (grip covering in the present invention). For example, see Japanese Patent Nos. 2141299 and 2851084. [Hereinafter, the coated body of the prior application. Today, there is a commercial product based on these [“Dr. GRIP” (registered trademark) manufactured by Pilot Corporation].

[0006] By the way, as a health disorder due to a long writing operation (including a writing operation), there are tendonitis and writing spasticity. In order to reduce the burden on the upper limb of writing work and prevent tendonitis or writing spasticity, the characteristics of individual finger length and grip pressure (grip strength) along with the friction coefficient of grip and elasticity of grip were used. Proper grip diameter is important.

A grip that is too thin or too thick for an individual puts an extra burden on the finger and causes the above-mentioned health problems.

In general, in individuals with long fingers, a slightly larger diameter is appropriate for individuals with short fingers in view of muscle fatigue. And the stronger the individual, the less muscle fatigue the thicker the grip.

When writing at a relatively slow speed for a long time, the diameter of the grip is preferably slightly larger, and when writing quickly in a short time, a slightly smaller diameter is appropriate in view of muscle fatigue.

[0010] Furthermore, in long-time writing work, a change in the grip diameter within a certain range in the middle is more likely to interrupt the sustained tension of the same muscle of the finger and to concentrate nerve fatigue in the same part of the cerebral motor cortex. It is effective in avoiding tenosynovitis and callospasm.

[0011]

[Problems to be solved by the invention]

 However, the grip diameter of a commercially available writing instrument is fixed and cannot be adjusted to an appropriate diameter according to the length of an individual's finger, nor can the diameter be adjusted according to the manner of writing.

[0012] Therefore, regardless of the length of the finger and the writing conditions, the existing average diameter must be used, which is one of the causes of the above-mentioned health problems.

The present invention has been made in view of such circumstances, and solves the above-mentioned problems. The present invention is made of a soft elastic material, and has a plurality of shaft holes which are detachably mounted on a pen body. Different diameter sets of grip coverings for writing implements, in which the grip coverings can be selectively used according to the writing style including finger length and writing pressure and are available as a set of replaceable accessories or supplies. To provide.

[0014]

[Means for Solving the Problems]

 In order to solve the problem, the present invention provides a grip covering for a writing instrument, which is made of a soft elastic material, has a shaft hole, and is removably covered on a pen body. The outer diameter set of the grips for writing instruments is formed so that the outer diameter of the mounting ends is the same and the outer diameter of the middle part is gradually different. It is characterized in that a plurality of types of holding diameters are selectively used and exchangeable accessories or supplies are provided according to a writing mode including pressure.

In some cases, a plurality of grips for writing implements are formed so that the taper angle from the front end to the middle part is the same, and the gripping diameter is gradually different from each other.
