Description
【発明の詳細な説明】 〔産業上の利用分野〕 この発明は板，特に厚板に点字が圧出して形成された点
字板およびその製造方法に関するものである。Description: TECHNICAL FIELD The present invention relates to a plate, particularly a Braille plate formed by pressing Braille on a thick plate, and a method for manufacturing the same.
盲人にも各種の施設，設備等を自由に利用できるよう
に，点字板によつて案内することは周知であり，例えば
これをエレベーターのかご内操作盤に適用したものが実
開昭５５−９６８６９号公報に示されている。It is well known that a blind person can use various facilities and equipment freely by using a Braille plate. It is shown in the publication.
第５図は上記文献等で示された施設に用いられる点字板
を示す縦断面図であり，板（厚さ１mm以下のアルミニウ
ム板，ステンレス鋼板，黄銅板，鋼板等）(1)に，裏面
から表面に向かつて突起(2)を押出し加工により圧出
し，これを点字形状に配列したものとなつている。FIG. 5 is a vertical cross-sectional view showing a Braille plate used in the facility shown in the above-mentioned documents, etc., the plate (aluminum plate having a thickness of 1 mm or less, stainless steel plate, brass plate, steel plate, etc.) (1), the back surface The protrusions (2) are extruded from the surface toward the surface by extrusion and are arranged in a Braille shape.
しかし，上記のものは，押出し加工により板(1)の表裏

ないようにする場合は，盤面を板(1)の厚さ分だけ切削
し，盤面と板(1)の表面が一致するように取り付けてい
る。However, in the case of the above, since the front and back of the plate (1) are simultaneously deformed by extrusion processing to form the protrusion (2), the plate (1)
Becomes thicker, processing becomes difficult. Therefore, if the board surface of the device (for example, the cover of the operation panel in the car) is a plate (1) having a thickness of 2 to 3 mm, make the plate (1) a thin plate and bond it with an adhesive, screw, or rivet. I am trying to fix it. In addition, when the thickness of the plate (1) is not shown on the board surface due to its appearance, the board surface is cut by the thickness of the board (1) so that the board surface and the surface of the board (1) are aligned. It is attached as follows.
また，第６図に示すように，板(1)に貫通穴(3)を穿設
し，これに丸頭のリベツト(4)を表面側に丸頭が現れる
ように打ち込んで，点字を形成することも行われてい
る。Further, as shown in FIG. 6, a through hole (3) is bored in the plate (1), and a round head ribet (4) is driven into this so that the round head appears on the surface side to form Braille. Things are also being done.
この外，鋳造，モールド等によつて作られた点字板を，

なければならず，実用的には頭径２mm以下，頭高0.5〜
0.6mmと極めて小形となり，製作が容易でないという問
題点がある。Among the conventional braille plates configured as described above, the one shown in FIG. 5 has a problem in that the thickness of the plate (1) of the braille plate appears on the board surface, which makes the product unattractive. Further, if the braille plate is provided so that the board surface and the surface of the board (1) are aligned, there is a problem that the processing of the board surface becomes expensive. In addition, in the case shown in FIG. 6, the round head rivets (4) must be arranged in a Braille shape, and in practical use, the head diameter is 2 mm or less and the head height is 0.5 to
The size is extremely small at 0.6 mm, and there is a problem that it is not easy to manufacture.
この発明は上記問題点を解決するためになされたもの
で，たとえ盤面の厚さが厚くても，点字が形成された板
の厚さが見えることなく，点字部分だけを突出させるこ
とができるようにした点字板およびその製造方法を提供
することを目的とする。The present invention has been made to solve the above problems. Even if the board surface is thick, it is possible to project only the Braille part without seeing the thickness of the plate on which the Braille is formed. It aims at providing the Braille plate and the manufacturing method thereof.

が上記表面から突出して形成された突起とを設けたもの
である。The braille plate according to the present invention is a thin wall formed between the bottom surface of the non-through holes and the surface, the plurality of non-through holes provided at the position of the Braille by being drilled from the back surface to the front surface of the plate. And a protrusion formed so as to protrude from the surface.

する工程とを備えたものである。Further, the method for manufacturing a braille plate according to the present invention comprises a step of forming a plurality of non-through holes from the back surface to the front surface of the plate, and a thin wall formed between the bottom surface of the non-through holes and the surface. And a step of forming a protrusion by pressing a predetermined braille constituting region of the portion onto the surface.
この発明においては、非貫通穴の薄肉部は板の厚さより
も薄く形成されるため、この部分の圧出により点字に適
合する突起が板の表面に形成される。In the present invention, since the thin portion of the non-through hole is formed thinner than the thickness of the plate, a protrusion adapted to Braille is formed on the surface of the plate by press-out of this portion.

ものである。1 to 3 are views showing an embodiment of the present invention.
The drawing is a sectional view taken along the line I--I of FIG. 2, FIG. 2 is a plan view, and FIG. 3 is a processing explanatory view, and (1) and (2) are the same as those of the conventional device.
図中，Ａ，Ｂはそれぞれ板(1)の表面及び裏面，(6)は裏
面Ｂから表面Ａに向かつて突起(2)とほぼ同径に穿設さ

の厚さよりも薄い薄肉部(2a)が形成され，これが圧出さ
れて表面Ａに突起(2)が形成される。そしてこれが点字
形状に配列されている。In the figure, A and B are the front and back surfaces of the plate (1), respectively, and (6) is a non-through hole bored from the back surface B to the front surface A with the same diameter as the projection (2), and its bottom surface. Between the surface A of the plate (1) the plate (1)
A thin portion (2a) thinner than the thickness of is formed and is extruded to form a protrusion (2) on the surface A. And this is arranged in a Braille shape.
第２図の突起(2)の配列は数字の「２」を表している。The array of protrusions (2) in FIG. 2 represents the number "2".
上記のように構成される点字板の加工手順を第３図によ
り説明する。The processing procedure of the Braille plate having the above structure will be described with reference to FIG.
まず，板(1)の裏面Ｂに非貫通穴(6)を穿設し，これを点
字形状（ただし裏文字）に配列する。この状態で第３図
に示すように，棒状体(7)の先端(7a)を非貫通穴(6)に挿

になつているため，薄肉部(2a)は表面Ａから突出し，突
起(2)が形成され点字が構成される。First, a non-through hole (6) is bored in the back surface B of the plate (1) and arranged in a Braille shape (provided that it is a reverse character). In this state, as shown in FIG. 3, when the tip (7a) of the rod-like body (7) is inserted into the non-through hole (6) and the other end (7b) is hammered, the thin portion (2a) is Since it is thin, the thin portion (2a) protrudes from the surface A, and the protrusion (2) is formed to form Braille.
薄肉部(2a)の厚さは，突起(2)の形成に適当な値に定め
ればよく，非貫通穴(6)の深さで自在に調節可能であ
る。また，突起(2)はハンマ等の簡単な工具で容易に形
成できるためコスト安となる。また，裏面Ｂの切削加工
は突起(2)とほぼ同じ小径の非貫通穴(6)だけであるた
め，穿設加工は容易で，かつ非貫通穴(6)は相互に連通
していないため，圧出加工作業の位置決めも容易であ
る。The thickness of the thin portion (2a) may be set to an appropriate value for forming the protrusion (2), and can be freely adjusted by the depth of the non-through hole (6). In addition, the projections (2) can be easily formed with a simple tool such as a hammer, which reduces the cost. Further, since the back surface B is cut only with the non-through holes (6) having the same small diameter as the protrusions (2), the boring process is easy and the non-through holes (6) are not connected to each other. ， Positioning of extrusion processing is easy.
なお，非貫通穴(6)の底部は第３図に示すように平面と
したが，山形になつていても差支えない。The bottom of the non-through hole (6) is a flat surface as shown in FIG. 3, but it may have a chevron shape.
第４図はこの発明の他の実施例を示す縦断面図で，板
(1)の厚さが特に厚い（５mm以上）の場合に適用したも
のである。FIG. 4 is a vertical sectional view showing another embodiment of the present invention.
It is applied when the thickness of (1) is particularly thick (5 mm or more).
すなわち，裏面Ｂから非貫通穴(6)の径よりも大径の円
柱状の座ぐり(6a)，又は皿状の座ぐり(6b)を加工し，そ
の後所定の非貫通穴(6)を穿設したものである。That is, a cylindrical counterbore (6a) or dish-shaped counterbore (6b) having a diameter larger than that of the non-through hole (6) is machined from the back surface B, and then a predetermined non-through hole (6) is formed. It has been drilled.
上記各実施例は，第５図のように板(1)を表裏同時に変
形させるものが，板(1)の厚さが厚い場合には不可能に
なるのと異なり，板厚に関係なくプレス作業により容易
に加工できる。また，材質も金属板だけでなく，厚板の
紙材，合成樹脂板等にも適用可能である。In each of the above embodiments, unlike the case where the plate (1) is deformed at the same time as the front and back as shown in FIG. 5, it becomes impossible when the plate (1) has a large thickness. Can be easily processed by work. Further, the material is not limited to a metal plate, and can be applied to a thick paper material, a synthetic resin plate, or the like.
以上説明したとおりこの発明では，板の裏面に複数個の
非貫通穴を穿設し，この非貫通穴の薄肉部を板の厚さよ
りも薄く形成し，この薄肉部を表面方向へ圧出して板の
表面に突起を形成して点字を構成したので，板の厚さが
厚い場合でも，点字が形成された板の厚さが見えること
なく，点字部分だけを突出させることができ，見栄えが
よく，かつコスト安の点字板が容易に得られる効果があ
る。As described above, in the present invention, a plurality of non-through holes are formed in the back surface of the plate, the thin portion of the non-through hole is formed thinner than the thickness of the plate, and the thin portion is extruded toward the surface. Since Braille is formed by forming protrusions on the surface of the plate, even if the plate is thick, it is possible to project only the Braille part without seeing the thickness of the plate on which the Braille is formed, and it looks good. A good and cost-effective Braille plate can be easily obtained.
