Description

[Technical Field]

[0001] The present invention relates to an underlay having a plurality of protrusions formed on at least one surface of a flat plate. [Background technology]

[0002] Various underlays are available that have multiple protrusions formed on one side of a flat plate. For example, Patent Document 1 describes an underlay (referred to as an "underlay" in Patent Document 1) that has multiple protrusions arranged on the surface of a flat plate. The protrusions have a rectangular or octagonal bottom shape and are tapered toward the tip. Between the multiple protrusions are lattice-shaped guide grooves that guide the tip of a writing implement. A manuscript is placed on the surface of this underlay. When a writing implement is scanned over the manuscript, the tip of the writing implement is guided by the guide grooves, and parallel lines, orthogonal lines, etc. are drawn on the manuscript without the need for a ruler or the like.

[0003] [Patent Document 1] Special Publication No. 3-62159 Summary of the Invention [Problem to be solved by the invention]

[0004] The writing pad described in Patent Document 1 has an array of pyramidal protrusions on its flat surface to allow for drawing parallel or orthogonal lines on a manuscript. Meanwhile, there are cases where people with disabilities who have difficulty writing characters or children who want to practice writing characters use writing pads with multiple protrusions to improve their writing disabilities or their writing learning abilities. Characters often contain curved parts, such as "strokes" and "stroke strokes." Therefore, writing pads that allow for drawing parallel or orthogonal lines are difficult to use to improve writing disabilities or their writing learning abilities.

[0005] In addition, some people use underlays when coloring. When using conventional underlays, writing implements such as colored pencils can slip too much, causing the colors to go outside the designated lines.

[0006] To provide an underlay that not only enables a user to write neatly but also promotes the adjustment of writing pressure and the stabilization of handwriting, improves writing disorders, and improves the ability to learn writing. [Means for solving the problem]

[0013] An embodiment of an underlay according to the present invention will be described below with reference to Figs. 1 to 4. Fig. 1 is an enlarged perspective view of a main part of an embodiment of an underlay according to the present invention. Fig. 2 is a front view of an embodiment of an underlay according to the present invention. Fig. 3 is an enlarged perspective view of a main part of an embodiment of an underlay according to the present invention. Fig. 4 is an enlarged front view of a main part of an embodiment of an underlay according to the present invention.

[0014] The underlay of this embodiment comprises a plastic base plate 1 and a plurality of protrusions 2. This underlay is used in a B5 or A4 notebook, or placed under a sheet of paper. Characters are written on the paper placed on the surface of the underlay using a writing implement such as a pencil (hereinafter referred to mainly as a "pencil").

[0015] As shown in Figures 1 and 2, the base plate 1 is a thin, rectangular plate slightly larger than B5 or A4 paper that is sandwiched between two sheets of notebook paper. Each corner of the plate is arc-shaped for safe use. The underlay is made of a variety of plastics, such as polyethylene terephthalate (PET), hard polyvinyl chloride, or soft polyvinyl chloride, and is transparent or translucent.

[0016] The multiple protrusions 2 are formed in a densely packed, evenly spaced dot pattern on one side of the front surface of the substrate 1. "Densely packed" means that the spacing between adjacent protrusions 2 and the width of each protrusion 2 are the same or approximately the same. "Evenly spaced" means that multiple protrusions 2 are arranged around a single protrusion 2 at the same intervals. One side of the back surface of the substrate 1 is formed flat. The multiple protrusions 2 are formed in a truncated cone shape. The multiple protrusions 2 are formed with a diameter, pitch (the length between the apexes of adjacent protrusions 2), and height that allow writing with a pencil on paper placed on a writing pad.

[0017] As shown in FIG. 4, the multiple protrusions 2 are arranged in a dense array of equilateral triangular meshes. That is, on one side of the substrate 1, equilateral triangular units with sides of 1.3 mm are arranged adjacent to each other, and a protrusion 2 is arranged at each vertex of each unit. Six protrusions 2 are arranged around one protrusion 2 at equal angles of 60°. On one side of the substrate 1, equilateral triangular units are arranged adjacent to each other, and adjacent protrusions 2 are arranged in a dense array with a pitch of 1.3 mm. In this way, the multiple protrusions 2 shown in FIG. 4 are formed like shark skin. Therefore, the multiple protrusions 2 arranged in a dense array of equilateral triangular meshes are formed on the substrate 1 at equal intervals and densely packed.

[0018] A large number of groove-like lines are formed between adjacently arranged protrusions 2. The groove-like lines are formed by drawing a plurality of horizontal lines La parallel to the upper and lower sides of the substrate 1, a plurality of oblique lines Lb inclined at an angle of 30° to the upper and lower sides of the substrate 1, and a plurality of oblique lines Lc inclined at an angle of 150° to the upper and lower sides of the substrate 1.

[0019] The multiple protrusions 2 are formed on the substrate 1 by thick printing. Thick printing involves dropping UV-curable ink, which hardens under ultraviolet light, at equal intervals on one side of the substrate 1, to form truncated cone-shaped protrusions 2 in a dot pattern. Therefore, the multiple protrusions 2 are formed on the inside of the substrate 1, excluding the outer peripheral edge 1a. In other words, the multiple protrusions 2 are not formed on the outer peripheral edge 1a of the substrate 1. The multiple protrusions 2 formed by UV thick printing are highly abrasion-resistant and scratch-resistant. As shown in Figure 3, the top surface of the truncated cone-shaped protrusions 2 is formed into a smooth, fillet-like curve without any corners. Therefore, the tip of a pencil does not get caught on the top surface of the protrusions 2 through the paper, and moves smoothly across the paper.

[0020] This underlay is configured as described above. It can be used by being sandwiched between two sheets of paper in a notebook, by placing a sheet of paper on top of the underlay, or by any other method. In either case, the paper is placed on top of the multiple protrusions 2 on the underlay. This underlay is used, for example, by users such as people with disabilities who have difficulty writing or children who are not used to writing, to practice writing.

[0021] The user of the underlay moves the tip of a pencil across the paper placed on the underlay. The slight resistance felt by the multiple protrusions 2 through the paper allows the user to practice writing. In other words, this underlay not only enables users to write neatly, but also encourages adjustment of writing pressure and stabilization of writing, thereby improving writing disorders and improving writing learning ability.

[0022] Characters contain many curved parts such as "hane" (strokes) and "harai" (stroke strokes). This writing pad has multiple protrusions 2 arranged in a finely detailed equilateral triangular mesh pattern. Therefore, the user of this writing pad can move a pencil so that the tip of the pencil lead curves. With this writing pad, the user can practice writing characters that include "hane" (strokes) and "harai" (stroke strokes). When you no longer need to practice writing characters using this writing pad, the back side can be used as a regular writing pad.

[0023] The embodiments of the underlay according to the present invention are not limited to the above, but include modifications and improvements within the scope of achieving the object of the present invention.

[0024] In the above embodiment, the multiple protrusions 2 are arranged in a dense array of equilateral triangular meshes. However, as shown in FIG. 5, the multiple protrusions 2 may also be arranged in a square mesh lattice array. The "equally spaced" multiple protrusions 2 shown in FIG. 5 means that four protrusions 2 are arranged at equal 90° angles around a central protrusion 2, and that the central protrusion 2 and the four protrusions 2 arranged around it are spaced at equal intervals. For example, in this underlay, multiple protrusions 2 are arranged at each vertex of a square unit with a side length of 1.0 mm on one side of the substrate 1. The square units are arranged adjacent to each other on one side of the substrate 1, and adjacent protrusions 2 are arranged in a lattice array with a pitch of 1.0 mm. Therefore, the multiple protrusions 2 shown in FIG. 5 are arranged in a square mesh lattice array. Therefore, the multiple protrusions 2 arranged in a square mesh lattice array are formed on the substrate 1 at equal intervals and densely packed.

[0025] Therefore, on one side of the substrate 1, a plurality of protrusions 2 are formed densely in a square mesh-like lattice arrangement. Numerous groove-like lines are formed vertically and horizontally between the protrusions 2 that are lined up next to each other in a dense lattice arrangement. The groove-like lines are formed in a checkerboard pattern by a plurality of horizontal lines Lx parallel to the top and bottom sides of the substrate 1 and vertical lines Ly parallel to the left and right sides of the substrate 1. This writing pad allows for effective practice of writing characters that have angular portions that intersect at right angles, such as the kanji character (kuchi).

[0026] The plurality of protrusions 2 may be arranged in a rectangular, square-mesh lattice arrangement. The plurality of protrusions 2 are arranged so that adjacent protrusions 2 in the horizontal direction are equally spaced, adjacent protrusions 2 in the vertical direction are equally spaced, and the spacing between the protrusions in the vertical and horizontal directions is different. The plurality of protrusions may also be arranged in a honeycomb-patterned mesh arrangement, with units each having a protrusion 2 at each corner of a hexagon. The plurality of protrusions 2 are arranged so that they are adjacent to each other at equal intervals of 120°. Whether the arrangement is a rectangular, square-mesh lattice arrangement or a hexagonal honeycomb-patterned mesh, the spacing between adjacent protrusions 2 is, for example, 1.3 mm to 1.0 mm.

[0027] In the above embodiment, the protrusion 2 is formed in a truncated cone shape with a fillet on the top surface. However, the protrusion 2 may be formed in a truncated cone shape with a corner on the top surface. Furthermore, the protrusion 2 may be formed in a truncated polygonal pyramid shape, such as a truncated square pyramid shape with a fret or a truncated square pyramid shape without a fillet.

[0028] In the above embodiment, the plurality of protrusions 2 are formed by thick printing. However, the plurality of protrusions 2 may also be formed by injection molding, embossing, or the like. In this case, the protrusions 2 may be formed up to the edge of the substrate 1. The embossed writing pad has a plurality of recesses formed on the back surface, but if the back surface is not used, it does not hinder penmanship practice.

[0029] In the above embodiment, each protrusion 2 is formed with a diameter of 0.6 mm, a pitch of 1.0 mm, and a height of 0.05 mm. However, the size and pitch of the protrusions 2 are not limited. For example, each protrusion 2 may be formed with a diameter of 0.9 mm, a pitch of 1.3 mm, or a diameter of 1.2 mm, a pitch of 1.9 mm, and a height of 0.05 mm. That is, the closely spaced protrusions 2 may be formed with a diameter of 0.3 mm to 2.0 mm, a pitch of 0.4 mm to 3.0 mm, and a height of 0.02 mm to 0.2 mm. The substrate 1 is not limited to a size of approximately B5 or A4, and various sizes, such as approximately B4 or A5, may be provided. By providing a wide variety of substrates 1 and writing pads with protrusions 2 of various sizes, it is possible to select a writing pad with protrusions 2 of a diameter and pitch that suits the level of disability of the disabled person using the writing pad or the level of a child wishing to improve their calligraphy learning ability.

[0030] In the above embodiment, the plurality of protrusions 2 are formed on one side of the substrate 1. However, the plurality of protrusions 2 may be formed not only on the front side but also on the back side of the substrate 1, i.e., on both sides. In this case, the diameter, pitch, and height of the protrusions 2 may be different between the front and back sides. Furthermore, the protrusions may be arranged in a lattice pattern of equilateral triangles on the front side of the underlay, and the protrusions may be arranged in a lattice pattern of squares on the back side.

[0031] In the above embodiment, the underlay has a single substrate 1 on which a plurality of protrusions 2 are formed. However, the underlay may also be formed by sandwiching various sheets between a plastic substrate 1 on which a plurality of protrusions 2 are formed and another plastic substrate 1 on which a plurality of protrusions 2 may or may not be formed. The sheets may be made of various materials, such as paper, metal plates such as iron or steel, non-ferrous metal plates such as copper or aluminum alloys, wood plates, rubber plates, or fabrics. Such sheets are sandwiched between two substrates 1 like a pouch. Furthermore, for example, kanji characters learned in first grade of elementary school may be written on the paper.

[0032] In the above embodiment, a pencil has been described as an example of a writing implement. However, the user may choose any writing implement they wish to use, such as a ballpoint pen, a fountain pen, or a felt-tip pen. This writing pad is suitable for use by people with disabilities and children, but may also be used for rehabilitation of cerebral infarction, hemiplegia, etc. Furthermore, this writing pad can be used when coloring, as it can help adjust the writing pressure and stabilize the writing stroke.

[0033] In summary, the underlay to which the present invention is applied is sufficient if it has the following configuration, and can take on a variety of different embodiments.

[0034] The underlay of the present invention comprises: a plastic substrate 1; a plurality of protrusions 2 arranged in a dense, equally spaced dot pattern on one surface of the substrate 1; Equipped with The plurality of protrusions 2 are formed at intervals and heights that allow scanning with a writing implement.

[0035] This underlay has a plurality of dot-patterned protrusions 2 formed on one side, and when a writing implement is placed on the paper, the protrusions 2 create a sense of resistance, preventing the writing implement from moving too much, allowing the user to consciously move the writing implement and practice writing.
