Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of Braille writing, in particular to a Braille writing board which can be flipped in sections. Background Art
[0002] Braille, also known as Braille, is an internationally accepted text symbol composed of six raised dots as its basic structure. It is a text symbol specially designed for blind students to read and write by touch. When learning, blind students usually use a Braille pen to write out the three-dimensional Braille characters, then turn the paper 180 degrees and read it by touch with their fingers.
[0003] At present, the Braille writing board is rectangular and consists of two pieces, the upper piece is called the cover plate and the lower piece is called the base plate. There are many rectangular holes on the cover plate and there are corresponding concave braille molds on the base plate.
[0004] Existing Braille tablets are designed to open and close on one side. In addition, Braille follows the rule of writing backwards and touching the front. Therefore, when using a Braille tablet, a blind student needs to sandwich the Braille paper in the middle of the tablet. After writing the Braille words, he or she needs to take out the Braille paper and turn it 180 degrees before reading by touch. After reading by touch, he or she needs to continue writing in the same way. This separates writing and reading for the blind student, making it difficult to detect writing errors and interrupting the writing process, leading to writing mistakes. Although there are also designs with three tablets connected end to end, which do not require taking out the Braille paper for touch reading, for mathematical calculations with complex steps, the board needs to be frequently turned over to touch the completed result and then apply it to the next step. This not only greatly reduces efficiency but also makes it easy to make mistakes, causing great difficulties for the blind student. Utility Model Content

[0037] like Figures 1-9 As shown, the preferred embodiment of the utility model:
[0038] A segmentally flippable Braille writing board comprises an upper plate unit 1, a middle plate unit 2 and a bottom plate unit 3 which are sequentially connected end to end in a rotating manner.
[0039] The upper plate unit 1 includes at least two upper templates flipped in the same direction, and a number of blind writing point holes 15 are provided on the upper template. In this embodiment, four upper templates are provided, namely the first upper template 11, the second upper template 12, the third upper template 13, and the fourth upper template 14. They are vertically aligned in sequence on the horizontal plane, and the left end portions are rotatably connected to the hollow plate provided in the middle plate unit 2 through the first connecting unit 5. The first connecting unit 5 is provided with a first rotating shaft 51.
[0040] The middle plate unit 2 is provided with a hollow plate corresponding to the upper template. In this embodiment, four hollow plates that can be flipped in the same direction are provided, namely the first hollow plate 21, the second hollow plate 22, the third hollow plate 23, and the fourth hollow plate 24. They are respectively connected to the first upper template 11, the second upper template 12, the third upper template 13, and the fourth upper template 14 through the first connecting unit 5 at the left end. The right ends of the first hollow plate 21, the second hollow plate 22, the third hollow plate 23, and the fourth hollow plate 24 are respectively connected to the bottom plate 36 provided in the bottom plate unit 3 through the second connecting unit 6, and a second rotating shaft 61 is provided in the second connecting unit 6.
[0041] The first rotating shaft 51 and the second rotating shaft 61 are parallel to each other.
[0042] The base plate 36 is a complete flat plate, and the upper surface 361 of the base plate 36 is provided with template areas corresponding to the upper templates. In this embodiment, the first template area 31, the second template area 32, the third template area 33, and the fourth template area 34 are respectively provided to correspond to the first upper template 11, the second upper template 12, the third upper template 13, and the fourth upper template 14. Each template area is provided with a number of braille molds 35 corresponding one-to-one to the blind writing point holes 15.
[0043] The hollow board includes a rectangular frame, and the frame is an inner hollow area 25 as a whole, and the area of the inner hollow area 25 is not less than the area occupied by the several blind writing point holes provided on the corresponding upper template. Taking the first hollow board 21 as an example: the first hollow board 21 includes a frame 26, and the frame 26 is a complete inner hollow area 25, and the area of the inner hollow area 25 is not less than the area occupied by the several blind writing point holes 15 provided on the corresponding first upper template 11. Figure 6 、 Figure 2 shown.
[0044] When in the folded state, the corresponding first upper template 11, the first hollow plate 21, and the first template area 31 are aligned vertically, and the same applies to other parts. Figure 1-Figure 3 shown.
[0045] The upper template, the hollow plate and the template area are all rectangular. The hollow plate is located between the upper template and the bottom plate 36, and the template area is provided with a plurality of dot molds 35. The template area protrudes to the inner hollow area 25 of the hollow plate and the top is flush with the upper surface of the hollow plate. Take the second hollow plate 22 as an example: the second hollow plate 22 is located between the second upper template 12 and the bottom plate 36, and the second template area 32 containing a plurality of dot molds 35 protrudes from the upper surface 361 of the bottom plate 36 and extends to the inner hollow area 25 of the second hollow plate 22, and the top height is flush with the upper surface of the second hollow plate 22, as shown in FIG. Figure 1 、 Figure 5 shown.
[0046] The four corners of the frame 26 of the hollow board are respectively provided with positioning pins 221. Taking the first hollow board 21 as an example: the center line of the positioning pins 221 at the left end of the first hollow board 21 and the center line of the positioning pins 221 at the right end are both parallel to the vertical frame 26, the center line of the positioning pin 221 at the upper left end and the center line of the positioning pin 221 at the upper right end, and the center line of the positioning pin 221 at the lower left end and the center line of the positioning pin 221 at the lower right end are both parallel to the horizontal frame 26. When the Braille paper is inserted on the four positioning pins 221, the Braille paper is in a standard placement position.
[0047] The positioning pins 221 are symmetrically arranged on the upper surface and the lower surface of the frame 26. Figure 5 shown.
[0048] The upper template and the bottom plate 36 are respectively provided with through holes that match the positioning pins 221 on the upper and lower sides of the frame 26. The through holes include a circular hole 16 at one end and an oblong hole 17 at the other end for facilitating the displacement of the positioning pin 221, so that the Braille paper is fixed between the upper plate unit 1 and the middle plate unit 2, and the position of the middle plate unit 2 and the bottom plate unit 3 is positioned.
[0049] Taking the fourth upper template 14 as an example: the fourth upper template 14 is provided with two circular holes 16 at the left end and two oblong holes 17 at the right end, which are respectively matched and plugged with the four positioning pins 221 on the upper surface of the fourth hollow plate 24 to install and fix the Braille paper; the two circular holes 16 at the left end and the two oblong holes 17 at the right end of the upper surface 361 of the bottom plate 36 are respectively matched and plugged with the four positioning pins 221 on the lower surface of the fourth hollow plate 24 for positioning.
[0050] When installing Braille paper, turn over the first upper template 11, the second upper template 12, the third upper template 13, and the fourth upper template 14 respectively, and place the Braille paper on the first hollow board 21, the second hollow board 22, the third hollow board 23, and the fourth hollow board 24 in a flat state. After the four positioning pins 221 on each hollow board are passed through the Braille paper, the round holes 16 and the oblong holes 17 on the first upper template 11, the second upper template 12, the third upper template 13, and the fourth upper template 14 are passed through the positioning pins 221 one by one and then flattened. The Braille paper is in the standard position.
[0051] The oblong holes 17 facilitate fine adjustment when positioning the positioning pin 221 , and therefore, the oblong holes 17 are all located on the same side to ensure accurate positioning of the Braille paper.
[0052] The upper surfaces of all upper templates are provided with a plurality of ridge lines 18, and the plurality of ridge lines 18 are horizontally parallel to each other and parallel to the long sides of the rectangle. The ridge lines 18 divide the blind writing point hole area into a plurality of areas, so that the blind students can easily identify the exact position of the blind writing point hole 15. Take the first upper template 11 as an example: three ridge lines 18 are horizontally arranged on the first upper template 11, which are respectively located at the top, middle and bottom of the rectangular blind writing point hole 15 area, dividing the blind writing point hole 15 area into an upper area and a lower area, so as to assist the blind students to distinguish which area the point is to be written when touching the ridge lines 18, and all the upper templates of the upper plate unit 1 are provided with the same ridge lines 18, such as Figure 4 shown.
[0053] The upper surface 361 of the bottom plate 36 is provided with a cutting unit 4 between two adjacent templates. The cutting unit 4 is provided with a paper cutter 43 for cutting the Braille paper fixed between the upper plate unit 1 and the middle plate unit 2.
[0054] The cutting unit 4 includes a guide rail 41 provided on the bottom plate 36, a slider 42 slidably mounted on the guide rail 41, and a paper cutter 43 mounted on the slider 42, so that after the braille writing on the first upper template 11 is completed, the slider 42 can be pushed to cut the braille paper horizontally, and the first upper template 11 and the corresponding fixed first hollow plate 21 can be turned over, and the braille writing can continue on the second upper template 12. At the same time, the braille convex dots on the back of the first upper template 11 can be touched by hand while writing.
[0055] The guide rail 41 extends from the left end of the bottom plate 36 to the left to form a placement end 411 for placing the slider 42. The width h of the placement end 411 should be smaller than the spacing H between two adjacent upper templates so that the placement end 411 is not touched when the upper template and the hollow plate are flipped. Figure 2 、 Figure 3 、 Figure 7 shown.
[0056] The bottom of the slider 42 is provided with a positioning protrusion 421, and the middle of the slider 42 is provided with a gap 422 for installing the paper cutter 43. Figure 8 、 Figure 9 shown.
[0057] Specific usage:
[0058] Turn over the first upper template 11, the second upper template 12, the third upper template 13, and the fourth upper template 14 section by section, place the Braille paper on the first hollow plate 21, the second hollow plate 22, the third hollow plate 23, and the fourth hollow plate 24 that are in a flat state, and after the four positioning pins 221 on each hollow plate are passed through the Braille paper, the round holes 16 and the oblong holes 17 on the first upper template 11, the second upper template 12, the third upper template 13, and the fourth upper template 14 are passed through the positioning pins 221 one by one and then flattened. The Braille paper is installed.
[0059] The blind student touches the ridge line 18 on the first upper template 11 with his hand, determines the position and starts to write Braille from top to bottom. After using the first upper template 11, he pushes the slider 42 with his hand to make the paper cutter 43 cut the Braille paper between the first upper template 11 and the second upper template 12, flips the first upper template 11 and the corresponding fixed first hollow plate 21 over, and continues to write Braille on the second upper template 12. At the same time, he can touch the Braille convex dots on the back of the first upper template 11 with his hand while writing. Especially when calculating mathematical formulas with complex steps, it is necessary to read the calculation results while touching them and apply them to the next calculation, that is, writing on the second upper template 12 while touching the Braille convex dots on the back of the first upper template 11 with his hand. Other templates are used in a similar manner, which makes it convenient for blind students to calculate complex formulas. It not only greatly improves the calculation efficiency, but also has high accuracy, providing blind students with an excellent experience.
[0060] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the purpose of the present invention and the claims, all of which are within the protection of the present invention.
