Description
本発明は、照光式アナログ指針表示装置に関し、特に、発光体からの光を指針体に導光する場合の光透過部材の表面を格子状又は菱形状のローレット加工とすることにより、指針体への光の伝達性を向上させ指針照光部の輝度を向上させるための新規な改良に関する。 The present invention relates to an illuminated analog pointer display device, and more particularly, to a pointer body by making the surface of a light transmitting member in the case of guiding light from a light emitter to the pointer body into a lattice or rhombus knurling process. The present invention relates to a novel improvement for improving the light transmission property and improving the brightness of the pointer illumination portion.
従来、用いられていたこの種の照光式アナログ指針表示装置としては、社内製作のみで、特に特許出願等を行っていないため、ここでは、従来構成を示す特許文献等を開示していないが、従来構成としては、図４及び図５に示すことができる。 Conventionally, as this type of illuminated analog pointer display device that has been used, since it is only manufactured in-house, and in particular has not filed a patent application etc., here is not disclosed the patent literature showing the conventional configuration, etc. Conventional configurations can be shown in FIGS. 4 and 5. FIG.
図４において、符号１で示されるものは、全体形状がほぼ箱型をなすケース体であり、このケース体１の前面開口２には透明体よりなる前面カバー板３が設けられている。
前記ケース体１の底板４上には、アナログ状のレベル表示面５を有するレベル表示体６が設けられており、このレベル表示体６の上部には、透明なアクリル樹脂からなる光透過部材７が設けられている。
In FIG. 4, what is indicated by reference numeral 1 is a case body whose overall shape is substantially box-shaped, and a front cover plate 3 made of a transparent body is provided in the front opening 2 of the case body 1.
A level display body 6 having an analog level display surface 5 is provided on the bottom plate 4 of the case body 1, and a light transmitting member 7 made of a transparent acrylic resin is provided above the level display body 6. Is provided.
前記レベル表示体６内には、ＬＥＤ等の発光体８が内設され、前記光透過部材７の上方で、かつ、前記ケース体１の上蓋９の下方位置には、Ｌ字型に曲折され導光体からなる指針体１０が前記レベル表示面５に対して横方向すなわち左右方向に移動自在に設けられており、この指針体１０の基部１１から延設された先端には指針照光部１２が形成されている。 A light emitting body 8 such as an LED is provided in the level display body 6, and is bent in an L shape above the light transmitting member 7 and below the upper lid 9 of the case body 1. A pointer body 10 made of a light guide is provided so as to be movable in the lateral direction, that is, in the left-right direction with respect to the level display surface 5, and the pointer illuminating section 12 is provided at the distal end extending from the base 11 of the pointer body 10. Is formed.
前記光透過部材７は、板状をなす全体形状がアクリル樹脂による透明板であり、その表面７ａは、樹脂射出成形による成形面、すなわち、平滑面のままで肉眼では透明状態であり、図５に示されるように前記表面７ａには何らの後処理はなされていない。 The light-transmitting member 7 is a transparent plate made of acrylic resin with a plate-like overall shape, and its surface 7a remains a molded surface by resin injection molding, that is, a smooth surface and is transparent to the naked eye. As shown in FIG. 4, the surface 7a is not subjected to any post-treatment.
従って、前述の従来構成において、図示しない電源を投入し、前記発光体８が点灯すると、この発光体８からの光は、前記光透過部材７及び表面７ａを経て前記指針体１０に入射され、この指針体１０に入射された光は、この指針体１０の基部１１から先端の指針照光部１２へ導光され、レベル表示面５に対する指針照光部１２の位置が明示される。 Accordingly, in the above-described conventional configuration, when a power source (not shown) is turned on and the light emitter 8 is turned on, light from the light emitter 8 is incident on the pointer body 10 through the light transmitting member 7 and the surface 7a. The light incident on the pointer body 10 is guided from the base 11 of the pointer body 10 to the pointer illumination section 12 at the tip, and the position of the pointer illumination section 12 with respect to the level display surface 5 is clearly indicated.
従来の照光式アナログ指針表示装置は、以上のように構成されているため、次のような課題が存在していた。
すなわち、光透過部材の表面は、何らの後処理がなされていない平滑面であるため、この光透過部材を透過した後の光は、図４の矢印で示されるように、同じ方向、すなわち、一方向への出射であるため、指針体に対する光の伝達性が低く、指針照光部における発光量が十分でなく、発光量の向上が切望されていた。
Since the conventional illuminated analog pointer display device is configured as described above, the following problems exist.
That is, since the surface of the light transmissive member is a smooth surface that has not been subjected to any post-treatment, the light after passing through the light transmissive member has the same direction, as indicated by the arrows in FIG. Since the light is emitted in one direction, the light transmission to the pointer body is low, the amount of light emitted from the pointer illumination portion is not sufficient, and an improvement in the amount of light emitted is desired.
本発明による照光式アナログ指針表示装置は、レベル表示面を有するレベル表示体が内設されたケース体と、前記レベル表示体の上面に形成された光透過部材と、前記ケース体の上蓋の下方で左右方向に移動自在に配設されＬ字型をなす指針体と、前記指針体の先端に形成され前記レベル表示面の外側に位置する指針照光部と、前記レベル表示体の後方で、かつ、前記光透過部材の内側に配設された発光体と、を備え、前記光透過部材の表面は、ローレット加工により形成された格子状又は菱形状の模様を有し、前記発光体からの光は、前記模様を有する前記表面から前記指針体の基部を経て前記指針照光部に導光される構成であり、また、前記光透過部材は、アクリル樹脂よりなる構成である。 An illuminated analog pointer display device according to the present invention includes a case body in which a level display body having a level display surface is provided, a light transmitting member formed on an upper surface of the level display body, and a lower part of the upper lid of the case body. An L-shaped pointer body that is movably disposed in the left-right direction, a pointer illumination portion that is formed at the tip of the pointer body and is located outside the level display surface, behind the level display body, and A light emitter disposed inside the light transmissive member, and the surface of the light transmissive member has a lattice-like or rhombic pattern formed by knurling, and light from the light emitter. Is configured to be guided from the surface having the pattern to the pointer illumination unit through the base of the pointer body, and the light transmitting member is configured of an acrylic resin.
本発明による照光式アナログ指針表示装置は、以上のように構成されているため、次のような効果を得ることができる。
すなわち、レベル表示体の上部に設けられた光透過部材の表面が、従来の平滑面ではなく、ローレット加工による格子状又は菱形状に形成された表面、すなわち、周知のアヤ目加工で構成されているため、光透過部材を通過した光は、図２の矢印で示されるように、多方向に散乱して指針体に入射するため、従来よりも光の伝達性が向上し、指針照光部の発光量が従来よりも増大し、より明確な指針表示を行うことができる。
Since the illuminated analog pointer display device according to the present invention is configured as described above, the following effects can be obtained.
That is, the surface of the light transmitting member provided on the upper portion of the level display body is not a conventional smooth surface, but a surface formed in a lattice shape or rhombus shape by knurling, that is, a known iris processing. Therefore, as shown by the arrow in FIG. 2, the light that has passed through the light transmitting member is scattered in multiple directions and enters the pointer body. The light emission amount is increased as compared with the prior art, and a clearer guideline display can be performed.
本発明は、発光体からの光を指針体に導光する場合の光透過部材の表面を格子状又は菱形状のローレット加工とすることにより、指針体への光の伝達性を向上させ指針照光部の輝度を向上させるようにした照光式アナログ指針表示装置を提供することを目的とする。 The present invention improves the transmissibility of light to the pointer body by improving the surface of the light transmitting member when light from the light emitter is guided to the pointer body by a grid or rhombus knurling process. It is an object of the present invention to provide an illuminated analog pointer display device that improves the brightness of a part.
以下、図面と共に本発明による照光式アナログ指針表示装置の好適な実施の形態について説明する。
尚、従来例と同一又は同等部分については同一符号を用いて説明する。
図１及び図２において符号１で示されるものは、全体形状がほぼ箱型をなすケース体であり、このケース体１の前面開口２には透明体よりなる前面カバー板３が設けられている。
前記ケース体１の底板４上には、アナログ状のレベル表示面５を有するレベル表示体６が設けられており、このレベル表示体６の上部には、透明なアクリル樹脂からなる光透過部材７が設けられている。
A preferred embodiment of an illuminated analog pointer display device according to the present invention will be described below with reference to the drawings.
Note that the same or equivalent parts as in the conventional example will be described using the same reference numerals.
1 and FIG. 2 shows a case body whose overall shape is substantially box-shaped, and a front cover plate 3 made of a transparent body is provided in the front opening 2 of the case body 1. .
A level display body 6 having an analog level display surface 5 is provided on the bottom plate 4 of the case body 1, and a light transmitting member 7 made of a transparent acrylic resin is provided above the level display body 6. Is provided.
前記レベル表示体６内には、ＬＥＤ等の発光体８が内設され、前記光透過部材７の上方で、かつ、前記ケース体１の上蓋９の下方位置には、Ｌ字型に曲折され導光体からなる指針体１０が前記レベル表示面５に対して横方向すなわち左右方向に移動自在に設けられており、この指針体１０の基部１１から延設された先端には指針照光部１２が形成されている。 A light emitting body 8 such as an LED is provided in the level display body 6, and is bent in an L shape above the light transmitting member 7 and below the upper lid 9 of the case body 1. A pointer body 10 made of a light guide is provided so as to be movable in the lateral direction, that is, in the left-right direction with respect to the level display surface 5, and the pointer illuminating section 12 is provided at the distal end extending from the base 11 of the pointer body 10. Is formed.
前記光透過部材７は、板状をなす全体形状がアクリル樹脂による透明板であり、その表面７ａは、図３で示されるように、周知のローレット加工により格子状又は菱形状となるように浅い形状の切削による直線溝を多数形成し、直線溝を形成しない部分との組合わせにより、全体として前記表面７ａが前述の格子状又は菱形状の模様（当業者ではアヤ目加工と称し、肉眼では曇硝子状）を呈することになる。 The light transmitting member 7 is a transparent plate made of acrylic resin with a plate-like overall shape, and its surface 7a is shallow so as to become a lattice shape or a rhombus shape by a known knurling process as shown in FIG. By forming a large number of straight grooves by cutting the shape and combining with the portion not forming the straight grooves, the surface 7a as a whole is the above-mentioned lattice-like or rhombus-like pattern (the person skilled in the art refers to the iris processing, (Cloudy glass).
従って、前述の構成において、図示しない電源を投入し、前記発光体８が点灯すると、この発光体８からの光は、前記光透過部材７及び表面７ａを経て前記指針体１０に入射され、この指針体１０に入射された光は、この指針体１０の基部１１から先端の指針照光部１２へ導光され、前記発光体８によって照光されているレベル表示面５に対する指針照光部１２の位置が明示される。 Accordingly, in the above-described configuration, when a power source (not shown) is turned on and the light emitter 8 is turned on, light from the light emitter 8 is incident on the pointer body 10 through the light transmitting member 7 and the surface 7a. The light incident on the pointer body 10 is guided from the base 11 of the pointer body 10 to the pointer illumination section 12 at the tip, and the position of the pointer illumination section 12 with respect to the level display surface 5 illuminated by the light emitter 8 is changed. It is clearly shown.
前述の場合、前記発光体８からの光は、前記光透過部材７を透過する際に、前記表面７ａの前述の模様により、図２で示されるように、その光の方向が一方向ではなく、多方向となって前記指針体１０に入射する。この現象により従来の一方向に揃う光と異なり、指針体１０内で反射する光の方向も多方向となり前記指針照光部１２へ導光される光量が従来よりも多くなり高輝度の指針照光部１２を得ることができる。 In the above case, when the light from the light emitter 8 passes through the light transmitting member 7, the direction of the light is not unidirectional as shown in FIG. 2 due to the pattern of the surface 7a. The light enters the pointer body 10 in multiple directions. Due to this phenomenon, unlike the conventional light aligned in one direction, the direction of the light reflected in the pointer body 10 is also multi-directional, and the amount of light guided to the pointer illuminating unit 12 is larger than that in the conventional case, and the pointer illuminating unit has a high luminance. 12 can be obtained.
