Description

Technical Field

[0001] The present invention belongs to the technical field of brush calligraphy, and particularly relates to a multi-functional adjustable electronic calligraphy grid ruler. Background Art

[0002] A calligraphy grid ruler is a special auxiliary tool for calligraphy practice and creation, aiming to help calligraphers or calligraphy enthusiasts accurately draw grids on paper, so as to better control the size and spacing of strokes, thereby improving the quality and aesthetics of calligraphy works. By providing an accurate grid-drawing function, it helps users improve their calligraphy skills, enhance the artistic expressiveness of their works, and provides strong support for the inheritance and development of calligraphy art.

[0003] Currently, the existing grid rulers on the market are all engraved in a similar template type and cannot adjust the grid size, with a single function. In the process of brush calligraphy creation, in order to solve the problems of inconsistent character sizes, unstable centers of gravity, and disproportionate proportions, it is necessary to fold grids. Traditional calligraphy creation uses the paper-folding method, where equal-sized grids or rows are divided by creases, so that each character occupies a fixed space. This method is not only time-consuming and laborious, but also leaves creases on the paper surface, affecting the creation effect.

[0004] A few years ago, when I was searching for "children's drawing boards" online to buy one for my child, I accidentally saw a kind of cold light luminous wire, which was used for decoration and mostly clamped on cloth curtains. So it gave me an inspiration. I thought if it was clamped on a felt, could it replace the grid? So I bought the luminous wire and clamped it on the felt according to the sizes of four-character and five-character large-character calligraphy as grids, and the effect was quite good. Later, I made a kind of ring for writing couplets, but the size could not be adjusted, so I could only make multiple rings of different sizes in a row. By selecting the size of the ring, the characters to be written could be of different sizes, but it was very troublesome.

[0005] Later, I began to study how to integrate the above functions. After several rounds of drawing, modifying, calculating, testing, modifying again, testing again... Finally, in April 2025, a "multi-functional adjustable electronic calligraphy grid ruler" was successfully developed. This grid ruler can write couplets in multiple specifications, as well as four-character and five-character large-character calligraphy, with multiple functions. Summary of the Invention

[0006] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a multi-functional adjustable electronic calligraphy grid ruler to solve the problems in the above background art.

[0007] The object of the present invention is achieved in this way: a multifunctional adjustable electronic calligraphy gridding device, which includes: a power module, a control module, a structural module, a circuit protection unit and a light source module; the light source module includes a circular ring and a positioning reference line array composed of multiple LED light strips, and the positioning reference line array includes multiple groups of circular rings, paper moving reference lines and common lines; the control module includes: a power switch, stepless dimming and a switching assembly; the switching assembly includes: a reset button and a multi-level control logic, which realizes a single-button triggering of a single group of circular rings and paper moving reference lines to light up or extinguish.

[0008] By utilizing the principle of electronic luminescence, the grid punch is placed under the calligraphy paper. The light source of its light source module can pass through the paper. The positioning reference line array composed of multiple LED light strips arranged on the grid punch can accurately realize grids of various sizes. The electronic grid punch does not require folding paper when writing, avoiding creases on the paper. During use, the folding step is omitted, which is more convenient and quicker.

[0009] Furthermore, the light source module also includes a special line for four-character banner writing and a special line for five-character banner writing, and the common lines include a center line, an upper left horizontal line, an upper right right angle line, a lower left horizontal line, and a lower right horizontal line; the special line for four-character banner writing includes a four-character upper left positioning line, a four-character upper right positioning line, a four-character inscription left line, and a four-character inscription right line; the special line for five-character banner writing includes a five-character upper left positioning line, a five-character upper right positioning line, a five-character inscription left line, and a five-character inscription right line; the control module also includes a downstream function key, and the downstream function key is used to trigger the downstream function key to jointly light up the corresponding special line for banner writing and the digital logo when the basic key is activated.

[0010] By setting multiple groups of circular rings and positioning reference lines, and coordinating with special lines for four-character banners and five-character banners, calligraphy works of various specifications can be gridded. They can be used for single-word practice of writing brush calligraphy with a width of 13-26cm, all couplet papers with a width of 16-40cm, four-foot-opening rice paper four-character banners, four-foot-opening rice paper five-character banners, four-foot-opening hollow scroll four-character banners, four-foot-opening hollow scroll five-character banners, four-character banners with a hollow scroll slightly smaller than four feet, and five-character banners with a hollow scroll slightly larger than four feet, increasing the applicability of this gridding device.

[0011] Furthermore, the power supply module includes a 5V DC power input, a switch / dimmer, and the switch / dimmer is electrically connected to the control module. The circuit protection unit includes a choke diode, and the choke diode is connected in series to the driving circuit of the LED strip. By using modern popular LED lighting technology, combined with a switchable assembly, a shunt switch, and a choke diode, a calligraphy grid with multiple functions and adjustable size specifications is realized. With a 5V power supply and a choke diode set in the circuit, it is safer and more reliable to use, and has strong luminous stability.

[0012] Furthermore, the structural module includes a housing, and a light-transmitting panel is provided at the upper end of the housing. The light source module is disposed inside the housing and below the light-transmitting panel; the control module is disposed on the control panel of the housing; the power supply module and the circuit protection unit are disposed inside the housing.

[0013] Furthermore, a ruler and a detachable felt are provided on the upper surface of the light-transmitting panel. The ruler is used to measure the data of the blank space at the upper end of the couplet paper when writing couplets, and accurate dimensions can be obtained. The advantage of the felt is to prevent the paper from moving when writing, and at the same time absorb bleeding ink.

[0014] Furthermore, the diameters of the rings are classified as 14 cm, 18 cm, 22 cm, and 26 cm, and the center line of the common line lights up in any basic mode. In the four-character large-character calligraphy mode, the four-character large-character calligraphy dedicated line, the number "4", and the common line light up synchronously; in the five-character large-character calligraphy mode, the five-character large-character calligraphy dedicated line, the number "5", and the common line light up synchronously. The downstream function keys include a four-character large-character calligraphy key and a five-character large-character calligraphy key; the control module further includes a reset key, and the reset key is used to turn off all the activated LED strips associated in the switching assembly; the digital identifier and the large-character calligraphy dedicated line are integrated on the same light-transmitting panel, the number "4" corresponds to the four-character large-character calligraphy mode, and the number "5" corresponds to the five-character large-character calligraphy mode, and is selectively lit by the four-character large-character calligraphy key or the five-character large-character calligraphy key.

[0015] This grid maker is small in size and light in weight, and is convenient to carry when participating in relevant calligraphy activities.

[0016] When using this grid maker to write large-character calligraphy, a large tabletop is not required, and an ordinary desk, coffee table, dining table, and chair can all be used.

[0017] A long roll of paper with a width of 34 cm can be cut into the length of a standard four-foot cut in half, which is convenient to operate and has accurate grid marking. It consumes very little power and has a low energy consumption cost.

[0018] Advantages of the present invention: By utilizing the principle of electroluminescence, the grid divider is placed under the calligraphy paper, and the light source of its light source module can penetrate the paper. With the positioning reference line array composed of multiple LED light strips arranged and laid out on the grid divider, various grids of different sizes can be accurately achieved. When using the electronic calligraphy grid divider, there is no need to fold the paper during writing, avoiding creases on the paper surface, eliminating the paper folding step in the creation process, and making it more convenient and fast.

[0034] When in use, it is convenient: When writing, there is no need to fold the paper. It can accurately mark the grid, is convenient and fast, and has strong practicality. It has many functions: Because it can be adjusted, it can write characters of various specifications. It is small in size: It is small in size and light in weight, making it convenient to carry. It is safe: Both types of grid rulers use a 5V DC power supply and can directly use a mobile phone charger, power bank, socket with a USB port, computer USB, etc. as the power supply for this device. It is economical: It is not only safe but also consumes very little power, and the energy consumption is very economical, solving the problem of having to fold the paper when writing couplets or large-character calligraphy in the past.

[0035] The implementation process is as follows: Function 1: Single-character practice: Practicing single characters is beneficial for mastering the writing method of the brush, the skill of pen movement, and the structure of the characters. At the same time, it can also make the characters of equal size, which is helpful for writing couplets and large-character calligraphy. This grid ruler is used for practicing single characters of 13 - 26 cm in writing with a writing brush.

[0036] 1.1 Power on: Insert the 5V power supply “24” and turn on the “Power Switch / Stepless Dimming” “25”. At this time, the center line “1” is constantly lit. This line can prevent the writing from deviating from the center and avoid writing the character shape crooked.

[0037] 1.2 Select paper: According to the size of the characters you want to write, select the appropriate paper. The paper should basically match the selected ring, and the four sides of the paper should be larger than the ring. Old books, old newspapers, etc. can all be used. It is better to buy yellow-edge paper for practice.

[0038] 1.3 Selection Button: According to the size of the characters you want to write, you can switch and select the ring that basically matches the paper by using the buttons in the switching assembly.

[0039] The first group: When pressing 26 - 1, "2" and "3" will light up at this time, which is suitable for writing characters about 13 cm in size.

[0040] The second group: When pressing 26 - 2, "4" and "5" will light up at this time, which is suitable for writing characters about 17 cm in size.

[0041] The third group: When pressing 26 - 3, "6" and "7" will light up at this time, which is suitable for writing characters about 21 cm in size.

[0042] The fourth group: When pressing 26 - 4, "8" and "9" will light up at this time, which is suitable for writing characters about 25 cm in size.

[0043] Note: The keys "3, 5, 7, 9" are the positioning lines for paper movement when writing couplets. Although these keys light up during single-character writing practice, their functions are ignored at this time.

[0044] Function 2: Writing couplets: It can write all couplet papers with a width of 16 - 40 cm.

[0045] 2.1 Power on: Insert the 5V power supply "24", turn on the "Power Switch / Stepless Dimming" "25", and at this time the central vertical line "1" will be constantly on. This line can prevent writing from deviating from the center and avoid writing distorted characters.

[0046] 2.2 Select couplet paper: When selecting couplet paper, its length and width should basically match the number of characters to be written.

[0047] 2.3 Selection Button: Select the corresponding ring according to the width of the couplet paper: The first group: When pressing 26 - 1, "2" and "3" will light up simultaneously, which is suitable for writing couplet papers with a width of 16 - 19 cm. Among them, "3" is the positioning reference line for paper movement.

[0048] The second group: When pressing 26 - 2, "4" and "5" will light up simultaneously, which is suitable for writing couplet papers with a width of 20 - 24 cm. Among them, "5" is the positioning reference line for paper movement.

[0049] The third group: When pressing 26 - 3, "6" and "7" will light up simultaneously, which is suitable for writing couplet papers with a width of 25 - 31 cm. Among them, "7" is the positioning reference line for paper movement.

[0050] The fourth group: When pressing 26 - 4, "8" and "9" will light up simultaneously, which is suitable for writing couplet papers with a width of 32 - 40 cm. Among them, "9" is the positioning reference line for paper movement.

[0051] For each of the above groups of rings, the size of the characters can be adjusted by writing the characters inside the ring or filling the ring.

[0052] 2.4. White Space: The upper white space of the couplet is called "Tian Tou" and the lower white space is called "Di Tou". Traditionally, "Tian Tou" is slightly larger than "Di Tou". However, for the sake of overall coordination and beauty, the upper and lower white spaces are mostly equal now. (For the convenience of description, couplets between 1 - 2 meters are hereinafter referred to as "small couplets", and couplets over 2 meters are hereinafter referred to as "large couplets"). The upper and lower white spaces of small couplets are generally between 5 - 10 cm. The upper and lower white spaces of large couplets are generally between 10 - 15 cm.

[0053] 2.5. Paper Shifting: Before the first writing on the couplet paper, the paper shifting distance needs to be measured. First, select the corresponding ring according to the width of the paper. For example, when the selected ring is pressed to 26 - 1, both the ring "2" and the positioning reference line "3" light up, and then operate according to the following situations: 2.5.1. Small Couplets: Set the upper white space of the couplet paper to 5 cm, measure it with the left - hand side ruler "29" on the surface of the grid - drawing tool. Then, press the upper side of "3" with the left index finger, press the lower side of the ring "2" with the right index finger, and move both hands horizontally upward while sticking to the surface of the grid - drawing tool. When the right index finger moves to the upper side of "3", release the left hand and let it return to the right index finger to alternate with the right index finger. Do the same for each character written.

[0054] (1) After shifting the last character, if the lower end is exactly 5 cm, then shift the paper by pressing the upper side of "3" after each character is written.

[0055] (2) After shifting the last character, if the remaining paper at the lower end is less than 5 cm, then set the paper - shifting position 1 cm below "3" each time. If the remaining paper at the lower end exceeds 5 cm after using this method, then evenly divide the excess part and the upper - end white space. Write the characters smaller and adjust several times in combination with the upper and lower white spaces.

[0056] (3) After shifting the last character, if the remaining paper exceeds 5 cm, then evenly divide the excess part and the upper - end white space. If the remaining paper exceeds a lot, the paper - shifting position can be set 1 cm above "3", and adjust several times in combination with the upper and lower white spaces.

[0057] 2.5.2. Large Couplets: Set the upper white space of the couplet paper to 10 cm, measure it with the left - hand side ruler "29" on the surface of the grid - drawing tool. Then, press the upper side of "3" with the left index finger, press the lower side of the ring "2" with the right index finger, and move both hands horizontally upward while sticking to the surface of the grid - drawing tool. When the right index finger moves to the upper side of "3", release the left hand and let it return to the right index finger to alternate with the right index finger. Do the same for each character written.

[0058] (1) After shifting the last character, if the lower end is exactly 10 cm, then shift the paper by pressing the upper side of "3" after each character is written.

[0059] (2) After moving the last character, if the remaining paper at the lower end is less than 10 cm, then set the position of each paper movement 1 cm below "3". If the remaining paper at the lower end exceeds 10 cm after using this method, then evenly divide the excess part and the upper blank space. The characters should be written smaller, and adjust several times in combination with the upper and lower blank spaces.

[0060] (3) After moving the last character, if the remaining paper exceeds 10 cm, evenly divide the excess part and the upper blank space. If the remaining paper exceeds a lot, the paper movement position can be set 1 cm above "3", and adjust several times in combination with the upper and lower blank spaces.

[0061] Function 3: Writing four-character horizontal inscribed boards on rice paper: 3.1 Laying the felt: First, lay a relatively thin white calligraphy and painting felt on the grid ruler. The advantage of laying the felt is to prevent the paper from moving when writing and can absorb the bleeding ink at the same time.

[0062] 3.2 Turning on the machine: Insert the 5V power supply "24" and turn on the "Power Switch / Stepless Dimming" "25".

[0063] 3.3 Selecting the keys: Press the "26 - 4" key and the "Four-character Horizontal Inscribed Board" key "28", and at this time, the number "4" is displayed on the panel. (Note: When writing four-character horizontal inscribed boards, although the positioning reference line "9" is lit, this function is ignored at this time).

[0064] 3.4 Placing the paper: Take a piece of four-foot double-fold (34X138 cm) rice paper, align the upper right edge of the paper with the center line of the horizontal line of the "Upper Right Right Angle Line" "15", and align the right edge of the paper with the right side of the vertical line of the "Upper Right Right Angle Line" "15" and place it well. Then align the upper left edge of the paper with the center line of the "Upper Left Horizontal Line" "10". At this time, the lower edge of the paper is exactly flush with the center lines of the "Lower Left Horizontal Line" "20" and the "Lower Right Horizontal Line" "21", and press the paper with a paperweight.

[0065] 3.5 Writing and moving the paper: After pressing it with a paperweight, write the first character. After writing the first character, use chalk or a pencil (or you can also use your fingernail) to draw a mark on the center line of the paper surface of the "Upper Left Positioning Line" "11", and then move the paper to the right so that the drawn mark coincides with the center line of the "Upper Right Positioning Line" "14", press the paper with a paperweight, and then write the second character. After writing the second character, operate according to the previous step, and so on until the fourth large character is written.

[0066] 3.6 Signing and stamping: After writing the four large characters, there is no need to move the paper anymore. Directly write the signature between the signature lines "16, 18" and stamp the seal.

[0067] Finally, wipe off the marks drawn above (if the marks are drawn with fingernails, there is no need to deal with them), and it is completed.

[0068] Function 4: Writing five-character large calligraphy on xuan paper 4.1. Place the felt pad: (Same as item 3.1).

[0069] 4.2. Turn on the machine: (Same as item 3.2).

[0070] 4.3. Select the button: Press the "26-3" key and the "Five-character large calligraphy" key "27", and at this time, the number "5" is displayed on the panel. (Note: When writing five-character large calligraphy, although the positioning reference line "7" is on, this function is ignored at this time).

[0071] 4.4. Place the paper: (Same as item 3.4).

[0072] 4.5. Writing and paper movement: After pressing down with the paperweight, write the first character. After writing the first character, use a piece of chalk or a pencil (you can also use your fingernail) to make a mark on the center line of the paper surface of the "Upper left positioning line" "12". Then move the paper to the right so that the marked trace coincides with the center line of the "Upper right positioning line" "13". Press the paper with the paperweight and write the second character. After writing the second character, repeat the above operation until the fifth large character is written.

[0073] 4.6. Sign and seal: After writing the five large characters, there is no need to move the paper anymore. Directly write the signature between the signature lines "17, 19" and then seal it. Finally, wipe off the trace drawn above (if it is a trace made by fingernail, no treatment is required), and it is completed.

Place the paper: Align the upper right edge line of the core part of the four-foot double-fold scroll painting (34X138cm) with the center of the horizontal line of the "Upper right right-angle line" "15", and align the right edge line of the core with the right side of the vertical line of the "Upper right right-angle line" "15". Then align the upper left edge line of the core with the center line of the "Upper left horizontal line" "10". Finally, observe the coverage of "10", "15", "20", and "21". If there is any deviation, adjust it up and down to make the coverage position appropriate.

[0086] Function 7: The painting core is slightly smaller than the four-foot double-width of the scroll. Some merchants make empty scrolls that are not 34X138cm, which is not a standard four-foot double-width.

[0087] This section mainly describes the method of paper feeding. Other items are similar to the above items.

[0088] Paper Feeding: First, measure the size of the painting core with a ruler to see how much smaller the length and width are compared to the standard four-foot double-width of 34X138cm. For example, if the measured painting core is 30X134cm, then the upper right edge line of the painting core is placed 2cm downward at the center of the horizontal line 15 away from the "upper right right angle line"; the right edge line of the painting core is 2cm to the left of the right side of the vertical line 15. The upper left edge line of the painting core is placed 2cm downward at the center of the horizontal line 10 away from the "upper left horizontal line". That is to say, when the painting core is small, the outer part is used to make up the number of the four-foot double-width.

[0089] The method of paper feeding for writing four characters and writing five characters is the same. For other steps, if writing four characters, refer to Function 5 "Writing Four-Character Scroll Calligraphy in Big Characters", and if writing five characters, refer to Function 6 "Writing Five-Character Scroll Calligraphy in Big Characters".

[0090] Function 8: The painting core is slightly larger than the four-foot double-width of the scroll: This section mainly describes the method of paper feeding. Other items are similar to the above items.

[0091] Paper Feeding: First, measure the size of the painting core with a ruler to see how much larger the length and width of the painting core are compared to the standard four-foot double-width. For example, if the measured painting core is 36X140cm, then the upper right edge line of the painting core is placed 1cm upward at the center of the horizontal line 15 away from the "upper right right angle line"; the right edge line of the painting core is 1cm to the right of the right side of the vertical line 15 away from the "upper right right angle line". The upper left edge line of the painting core is placed 1cm upward at the center of the horizontal line 10 away from the "upper left horizontal line". That is to say, when the painting core is larger than the standard four-foot double-width, the extra part can be extended to the outer part.

[0092] The method of paper feeding for writing four characters and writing five characters is the same. For other steps, if writing four characters, refer to Function 5 "Writing Four-Character Scroll Calligraphy in Big Characters", and if writing five characters, refer to Function 6 "Writing Five-Character Scroll Calligraphy in Big Characters".

[0093] Function 9: When writing on a long roll of paper, the paper can be cut into a length of 138 cm. If using a 20m, 30m, 50m, or 100m long roll of paper, after writing the inscription for each calligraphy piece, do not move the paper, and use a paperweight to press the paper firmly. Then, use scissors to cut along the outside of the stainless steel edge strip on the left side of the grid ruler. Whether writing four-character or five-character large-character calligraphy, the cut paper is exactly the length of a four-foot cut paper, which is 138 cm.

[0094] Function 10: It is possible to create large-character calligraphy on a relatively small tabletop. When using the DKQ-B type grid ruler to write large-character calligraphy, there is no need for a large tabletop. Only a tabletop with a length of 80 cm and a width of 60 cm is required for operation. It can also be written on an ordinary desk, dining table, coffee table, bedside table, or the surface of an ordinary chair. Even if there is no spacious room to place a large tabletop, this DKQ-B type grid ruler can still be used to write large-character calligraphy in the size of a four-foot cut paper.
