Abstract

The invention provides a writing tool which comprises a pen core, a tip sleeve, a middle section, a soft sheath, a lower rod of the pen and the like. The outer periphery of the cross section of the middle section pen holding part of the pen is triangular, the outer periphery of the cross section of other parts of the middle section is circular, and meanwhile, the soft sheath arranged outside the middle section is barrel-shaped, so that an 'inner triangle' structure of the pen holding part is formed. The outer surface of the middle section covered by the soft sheath is provided with raised anti-skid patterns; the inner surface of the soft sheath is provided with concave anti-skid patterns. When the pen is not in use, the middle section of the pen is cylindrical, the aesthetic of the masses is met, when the pen is in use, the soft sheath of the pen is sunken into a triangular shape, the contact part of the finger and the middle section is a plane, the finger fatigue is greatly relieved, the pen is more stable and skid-proof, the ergonomics is better met, and meanwhile, a writer can be enabled to maintain a correct pen holding posture.

Description

Writing tool

Technical Field

The invention relates to the field of writing tools, in particular to a pen with more comfortable hand feeling.

Background

The currently known finger holding parts of neutral pens, ball pens, pencils, mechanical pencils and the like are mostly cylindrical, and the contact part of the finger and the pen is small, so that the finger is easy to fatigue during long-time writing.

Although the existing part of pens are added with a soft sheath at the pen holding position, or the pen holder is directly made into a triangle shape. The soft sheath can slightly reduce writing fatigue, but the nature is the same, and the contact area of the finger and the pen is not increased; the triangular pen with the pen holder greatly increases the contact area between the finger and the pen, has stable pen holding and better hand feeling, and does not accord with the aesthetic sense of the public.

Disclosure of Invention

The invention aims to provide the writing tool which not only keeps the cylindrical shape of the penholder which accords with the mass aesthetic, but also has the advantages of stable and comfortable holding of the triangular pen of the penholder, and better hand feeling than the prior pen with the soft sheath, and greatly reduces the writing fatigue.

The main technical content of the invention is as follows:

a writing instrument, characterized by: the outer periphery of the cross section of the middle section (3) E to F is triangular, the outer periphery of the cross section of the middle section (3) C to E and the outer periphery of the cross section of the middle section (F to D) are circular, and meanwhile, the soft sheath (4) arranged outside the middle section (3) is barrel-shaped, so that an 'inner triangle' structure between the pen holding parts E to F is formed; the outer surface between the middle sections (3) C and D is provided with raised anti-skid patterns; the inner surface of the soft sheath (4) is provided with concave anti-skid patterns.

The invention has the beneficial effects that: by adopting the scheme, when the pen is not in use, the middle section part of the pen is cylindrical, the aesthetic of the masses is met, when the pen is in use, the soft sheath of the finger pen holding part is inwards sunken into a triangle, the contact part of the finger and the middle section is a plane, the finger fatigue is greatly relieved, the pen holding is more stable and skid-proof, the ergonomics is more met, and meanwhile, the writer can be enabled to maintain a correct pen holding posture.

Description of the drawings:

the invention is further described below with reference to the drawings and examples.

FIG. 7 is a schematic cross-sectional view of a writing instrument taken along the line A of FIG. 5 according to an embodiment of the present invention;

fig. 8 is a schematic cross-sectional view of a writing instrument according to an embodiment of the present invention along a central axis of a middle section when a soft sheath is tightly attached to the middle section in a pen-holding state.

Fig. 9 is a schematic diagram of a cross-section of the writing instrument of fig. 8 along point B according to an embodiment of the present invention.

The specific embodiment is as follows:

examples: as shown in fig. 1 and 2, the writing tool according to the present embodiment includes a tip sleeve (1), a pen core (2), a middle section (3), a soft sheath (4), and a lower pen rod (5); the tip sleeve (1) is in a cone shape, is in threaded connection with the middle section (3), the middle section (3) is in threaded connection with the lower pen rod (5), the lower pen rod (5) is in a cylindrical shape with the outer diameter of about 1 cm, and the ratio of the outer diameter of other accessories to the size of the lower pen rod (5) is shown in figure 1; the soft sheath (4) is arranged on the periphery of the middle section (3), and the pen core (2) is arranged inside the tip sleeve (1), the middle section (3) and the pen lower rod (5). As shown in fig. 3, 5 and 7, the outer circumferences of the cross sections of the C-E part and the F-D part of the middle section (3) are circular, so that the soft sheath (4) is cylindrical in the non-use state; as shown in fig. 4 and 6, the outer periphery of the cross section between the pen holding parts E to F of the middle section (3) is triangular, so that when a finger holds a pen, the soft jacket (4) is tightly attached to the middle section (3), the cross section of the soft jacket (4) is changed into triangular, as shown in fig. 8 and 9, the contact part of the finger and the soft jacket (4) is a plane, so that the finger fatigue is greatly relieved, the pen holding is more stable, the ergonomics are more met, and meanwhile, a writer can maintain a correct pen holding posture. As shown in FIG. 2, the length from the point G at the top end of the pen point of the writing tool to the point E at the pen holding position of the middle section (3) is 22 mm, and the length from the point E at the pen holding position of the middle section (3) to the point F is 19 mm. The outer surface of the middle section (3) is provided with convex anti-slip lines, and the inner surface of the soft sheath (4) is provided with concave anti-slip lines, so that hands are not easy to slip during writing.
