Description

[Detailed Description of the Invention] The present invention relates to a writing instrument holder that is attached to a writing instrument such as a pencil, sharp pencil, or ballpoint pen.

Various holders have been proposed for teaching young children the correct way to hold a writing instrument. Such a conventional holder has a main body that is cylindrical or becomes cylindrical when attached to a writing instrument, and has holes for positioning the thumb, index finger, and middle finger.

With such conventional holders, it is possible to easily teach the correct way to hold the writing instrument regarding the positional relationship of each finger, but it is not possible to teach how far away from the tip of the writing instrument the writing instrument should be held. Also, many writing instruments have a hexagonal shape,
When holding such a hexagonal writing instrument, the correct way to hold it is to place each finger on the surface of the hexagonal prism, but when using a conventional holder, the positioning hole does not always open on the surface. For this reason, there is a risk that the corners, which are the boundaries between the surfaces, may become creased when placed with a finger.

The present invention was made to improve the above-mentioned problems of the conventional writing instrument holder, and in particular, it is a writing instrument holder that allows the user to learn the correct way to hold a hexagonal columnar writing instrument naturally without any special instruction. The purpose is to provide

In order to achieve this object, the holder according to the present invention has six protrusions formed at equal intervals on the peripheral edge of the tip of the cylindrical body, and three protrusions also formed on the body of the cylindrical body at equal intervals in the circumferential direction. A hole for holding a finger is formed, and the center line in the length direction of this hole is made to substantially match the longitudinal line passing through the apex of the protrusion, and the protrusion is connected to the tapered part of the tip of the hexagonal columnar writing instrument. The gist of this is that by aligning it with the wavy portion that forms the boundary with the surface of the column, the finger hole opens into the surface of the hexagonal column.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is an overall perspective view of the writing instrument holder according to the present invention. The cylindrical body 1 of the writing instrument holder is molded from a soft material such as rubber or synthetic resin, and its inner diameter is the same as that of the writing instrument holder when attached to the writing instrument. On the other hand, the inner circumferential surface is pressed to the extent that it does not shift.

Six protrusions 2 are formed at equal intervals on the peripheral edge of the tip of the cylindrical body 1, and three finger hooks of the same shape are formed on the body of the cylindrical body 1 at equal intervals in the circumferential direction. A long hole 3 for... is formed. Here, the positional relationship between the protrusion 2 and the elongated hole 3 is a longitudinal line passing through the center line _l1 in the longitudinal direction (axial direction of the cylindrical body) of the elongated hole 3 and the apex 2a of the protrusion 2. The relationship is such that l ₂ is approximately the same. Thus, a long hole 3 is provided at every other protrusion 2.

FIG. 2 is a perspective view showing a state in which a holder is attached to a hexagonal columnar pencil 4 used as a writing instrument. A plurality of protrusions 2 of the cylindrical main body 1 are attached to the wavy part 5 formed at the boundary between the tapered part 4a formed by sharpening the tip of the pencil 4 and the hexagonal columnar surface 4b of the pencil 4. Align the uneven parts consisting of. Then, as mentioned above, the apex 2 of the protrusion 2
Since the longitudinal line l ₂ passing through a and the longitudinal center line l ₁ of the elongated hole 3 approximately coincide, the elongated hole 3 is connected to the pencil 4.
The opening will be in the surface area.

Here, when the uneven part consisting of a plurality of protrusions 2 and the wavy part 5 are aligned, the surface 4b of the pencil 4 will protrude slightly from the uneven part, as shown in FIG. The amount of output is considered to be approximately constant even though there are individual differences. Therefore, by setting the distance between the protrusion 2 and the elongated hole 3 to an appropriate value, the pencil 4 can be gripped at a portion that is the most appropriate distance away from the tip. Further, since the elongated hole 3 opens on the surface of the pencil 4, each of the thumb, index finger, and middle finger can be appropriately placed on the surface.

FIG. 3 is an end view of the writing instrument holder of the present invention, in which a hexagonal columnar portion 6 is formed in at least a part of the inner circumference of the cylindrical body 1, and the outer periphery of the hexagonal columnar writing instrument inserted through the hexagonal columnar portion 6. I try to keep the parts. Therefore, in this embodiment, when the cylindrical main body 1 is attached to a writing instrument, the hole 3 opens into the surface of the writing instrument without any alignment. In the drawing, all three long holes 3 have the same shape so that they can be used at any position, but the holes may have different shapes for each finger.

As explained above, according to the writing instrument holder according to the present invention, when a child or the like uses a hexagonal column-shaped writing instrument, he or she does not put his or her finger on the corner of the boundary between the surfaces of the hexagonal column, and the above-mentioned The holder can be learned how to hold it correctly without any special instruction, and the holder itself is easy and inexpensive to manufacture.

[Brief explanation of the drawing]

FIG. 1 is an overall perspective view of a writing instrument holder according to the present invention, FIG. 2 is a perspective view showing the writing instrument holder attached to a writing instrument, and FIG. 3 is an end view of the writing instrument holder. In the drawings, 1 is a cylindrical body, 2 is a protrusion, 2a is the apex of the protrusion, 3 is a hole, 4 is a writing instrument, 5 is a wavy part, l ₁
is the center line of the hole, and l ₂ is the line passing through the apex of the protrusion.

Claims (1)

[Scope of utility model registration request] To be attached to a writing instrument, a cylindrical body having an inner diameter that is approximately the same as the diameter of the writing instrument and at least a portion of the inner periphery is a hexagonal column has a tapered portion at the tip and its tip when attached to a hexagonal column. Six protrusions are formed at equal intervals to match the wavy shape formed at the boundary with the prismatic surface, and three finger rests are provided on the body of the main body at equal intervals in the circumferential direction. A writing instrument holder characterized in that holes are formed, and the longitudinal center lines of these holes are made to substantially coincide with the longitudinal line passing through the apex of the protrusion.
