Description

TECHNICAL FIELD

[0001] The present application relates to the field of writing tools, in particular to a pencil. BACKGROUND

[0002] As one of the indispensable stationery in daily learning and office work, pencil has undergone hundreds of years of evolution and development. From the original natural graphite rod to the modern finely processed wooden wrapped pencil, its design has been continuously optimized to meet the needs of different groups of people.

[0003] The common pencil on the market at present mainly includes hexagonal rod, round rod and triangular rod and the like. Among them, the pencil used by children and students tends to adopt hexagonal rod and triangular rod design to guide the correct grip posture. However, due to the large curvature of the triangular pencil, beginners will produce "hugging" when holding the pencil. "Hugging" usually means holding the pencil tightly in the hand, and the fingers are wrapped around the pencil in a relatively compact manner, similar to the action of "hugging", rather than the more conventional and natural "three-point grip posture".

[0004] In addition, the grip position of many users will be pinched at the junction of the cut and uncut parts, and the grip position is too close to the pencil tip, which affects the observation of the pencil tip and is not conducive to writing. CONTENT OF THE INVENTION

[0005] The present application provides a pencil which helps to optimize the grip posture of the user and has good comfort. The following technical solutions are adopted:

[0006] A pencil, comprising a pencil shaft, the cross section of the pencil shaft is circular; a straight strip-shaped protrusion is arranged on the surface of the pencil shaft, and the protrusion is arranged along the length direction of the pencil shaft; the protrusion is provided with one or more.

[0007] By adopting the above technical solution, the pencil shaft is designed as a circular cross section, and the outer wall is a smooth arc surface, which has a good holding feeling. The arrangement of the protrusion can provide a calibration point. When holding the protrusion, the fingers will feel uncomfortable, so beginners can avoid the protrusion when holding the pencil to correct the grip posture.

[0008] In addition, after cutting, the protrusion forms a high cutting surface at the junction of the pencil tip and the pencil shaft, which makes it easier for beginners such as children to grasp the correct pencil holding height and reduces the problem of line of sight obstruction caused by holding the pencil too low.

[0009] Preferably, the protrusion is provided with three and is arranged around the periphery of the pencil shaft.

[0010] By adopting the above technical scheme, the three protrusions can be evenly distributed on the circumferential side of the pencil shaft, the included angle between the adjacent two protrusions and the center position of the pencil shaft is 120°, so that a holding point position can be formed between the adjacent two protrusions, thereby better correcting the holding posture of the user, and helping to develop a "three-point holding posture" pencil holding posture.

[0011] Preferably, the cross-sectional shape of the protrusion is any one, two or three of a square, a sector, a triangle, an arch, and a horseshoe.

[0012] By adopting the above technical scheme, the protrusion of the pencil has multiple cross-sectional shape designs, which can adapt to the pencil holding habits and needs of different users. Specifically, the selection of square, sector, triangle, arch, horseshoe and the like provides different degrees of pressure feedback and support force when the protrusion is contacted by the fingers, effectively guiding the user to form a correct "three-point holding posture". At the same time, the diversified shape design also adds differentiated characteristics to the product appearance, meeting the personalized market demand.

[0013] Preferably, the diameter of the cross section of the pencil shaft is 5mm-11.5mm; and the diameter of the circumscribed circle of the cross section of the pencil as a whole is 7mm-12mm.

[0014] By adopting the above technical scheme, the cross-sectional diameter of the pencil shaft is set in the range of 5mm-11.5mm, which can ensure that the pencil has an appropriate thickness, which is convenient for children to hold, and does not increase the carrying burden due to being too thick. At the same time, the diameter of the circumscribed circle of the cross section of the pencil as a whole is controlled between 7mm-12mm, so that the outer dimension of the protrusion is kept within a small range, so that the pencil is more in line with the palm in appearance, which helps to improve the writing experience.

[0015] Preferably, a coating layer is arranged on the surface of the pencil shaft, and the coating layer is a colored varnish coating layer.

[0016] By adopting the above technical scheme, the colored varnish coating layer can form a clear color difference between the pencil tip after being sharpened and the pencil shaft that has not been sharpened, so as to guide the holding height of children.

[0017] In summary, the present application includes at least one of the following beneficial technical effects:

[0018] 1. The pencil shaft of the pencil adopts a circular cross section and is provided with straight strip-shaped protrusions on the surface, a holding point position is formed between adjacent two protrusions, and the protrusions can provide calibration points, thereby better correcting the holding posture of the user, and helping to develop a correct pencil holding habit of "three-point holding posture";

[0019] 2. After cutting, the convex at the joint of the pencil tip and the pencil shaft forms a higher cutting surface, which makes it easier for beginners such as children to hold the pencil at the correct height, reducing the problem of visual obstruction caused by holding the pencil too low; the pencil shaft surface is provided with a colored varnish coating, which can effectively distinguish the pencil tip and the pencil shaft, guide the holding height, and increase the writing field of view;

[0020] 3. The convex has various cross-sectional shape designs, which can adapt to the habits and needs of different users. BRIEF DESCRIPTION OF DRAWINGS

[0024] In the drawings, the marks are: 1, pencil shaft; 2, convex. DETAILED DESCRIPTION

[0025] The following will be described in detail in combination with the drawings Figures 1-3 The present application will be further described in detail.

[0026] The pencil provided by the embodiment of the present application, with reference to Figure 1 , comprises a pencil shaft 1 and a straight strip-shaped convex 2 arranged on the surface thereof, wherein the convex 2 is arranged along the length direction of the pencil shaft 1, and the number thereof is one or more, which achieves the purpose of optimizing the pencil holding posture.

[0027] Specifically, with reference to Figure 1 and Figure 2 , the cross section of the pencil shaft 1 is designed as a circle, and the diameter d can be selected as any value in the range of 5mm to 11.5mm. For example, 10mm can be selected as the size version for children, or 6mm can be selected as the adult version. In addition, the diameter D of the circumscribed circle of the entire pencil (including the convex 2) is limited to 7mm to 12mm, so as to limit the volume of the convex 2. After the user's finger is pressed on the convex 2, a strong uncomfortable feeling is generated, and even a painful feeling is generated after a long time of pressing, thereby achieving a better positioning and correcting effect.

[0028] The protrusions 2 on the pen barrel 1 can be flexibly designed in various styles as needed. For example, the cross-sectional shape of a single protrusion 2 can be one of the common geometric forms such as square, fan, triangle, arch, or horseshoe, or it can be freely combined from one or more of these types. If a square shape is used, its regular edges are easy to identify, making it easier for beginners to grasp the correct application point; if an arch shape is used, the curved surface provides better wrapping performance, thus reducing fatigue caused by prolonged holding. In addition, the diverse shape design also adds a differentiated feature to the product's appearance, meeting the personalized market demand.

[0029] Furthermore, the total number of protrusions 2 is preferably three, evenly distributed around the periphery of the pen barrel 1. The two adjacent protrusions 2 are distributed at an angle of 120°, which can form a grip point between the two adjacent protrusions 2, thereby better correcting the user's grip posture and helping to develop a "three-point grip" pen-holding posture.

[0030] Reference Figure 3 After the pencil is cut, the protrusion 2 forms a higher cutting surface at the junction of the tip and the barrel 1, which makes it easier for children and other beginners to hold the pencil at the correct height and reduces the problem of vision obstruction caused by holding the pencil too low.

[0031] In addition, to further enhance the product's usability and durability, a colored varnish coating can be added to the outer surface of the pen barrel 1 and the protrusion 2. Common colors such as black and red can be used, or other colors can be employed. This coating not only improves the grip but also indicates the appropriate pen-holding height through the color difference between the pen barrel and the pen tip after sharpening.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
