死角補助装置Blind spot assist device
　本発明は、障害物によって遮られる死角領域の像を視認させる死角補助装置に関する。 The present invention relates to a blind spot assisting device for visually recognizing an image of a blind spot area blocked by an obstacle.
　特許文献１には、車両のフロントピラーなどの障害物によって遮られる死角領域の像を視認させる死角補助装置が開示されている。この装置は、死角領域の像を表す光を透過可能な第１ミラーと、第１ミラーに入射した光をユーザ側へと反射させる第２ミラーとからなる一対のミラーの反射作用により死角領域の像をユーザに視認させる。一対のミラーは、第１ミラー越しに見える像と、第２ミラーに映る像とが連続するように調整されている。そして、第１ミラーのユーザ側には、余計な外光がユーザ側へと反射しないように、複数の遮光板（ルーバー）が設けられている。 Patent Document 1 discloses a blind spot assisting device that visually recognizes an image of a blind spot area obstructed by an obstacle such as a front pillar of a vehicle.

　遮光板があることによる表示の見づらさを緩和するためには、複数の遮光板それぞれの第１ミラーに対する傾斜を、想定されるユーザの視点位置に応じて適切に設定する必要がある（例えば特許文献１の図４参照）。しかし、使用環境（例えば、ユーザ毎の体格の違いや、ユーザの姿勢や位置など）によって想定される視点位置が変化するため、何の対策も施さなければ、あるユーザにとっては遮光板があることによる表示の見づらさが適切に緩和されない。 In order to alleviate display difficulty due to the presence of the light shielding plate, it is necessary to appropriately set the inclination of each of the plurality of light shielding plates with respect to the first mirror according to the assumed viewpoint position of the user (for example, patents).

　本発明の一実施形態に係る死角補助装置を、図面を参照して説明する。 A blind spot assisting device according to an embodiment of the present invention will be described with reference to the drawings.
（第１実施形態）
　本発明の第１実施形態に係る死角補助装置１００は、図１に示すように、車両１内に配置される。車両１において、ユーザ（主に、ステアリング１０が配置された運転席に着座する運転者）は、フロントガラス２０とサイドガラス３０，４０越しに、車両１外部の風景を視認する。しかし、何の対策も施さなければ、ユーザは、ピラー（フロントピラー）５０,６０によって遮られて死角となる領域（死角領域Ｄ。図２参照）の像を視認できない。 (First embodiment)
The blind spot assisting device 100 according to the first embodiment of the present invention is disposed in a vehicle 1 as shown in FIG. In the vehicle 1, a user (mainly a driver seated in a driver's seat on which the steering 10 is disposed) visually recognizes the scenery outside the vehicle 1 through the windshield 20 and the side glasses 30 and 40. However, if no measures are taken, the user cannot visually recognize the image of the area (dead area D, see FIG. 2) that is blocked by the pillars (front pillars) 50 and 60 and becomes a blind area.
　死角補助装置１００は、上記のように生じる死角領域Ｄ内の像を視認可能とする。死角補助装置１００は、ピラー５０，６０のうち、右側のピラー５０に図示しないホルダ部材を介して配置される。 The blind spot assisting device 100 makes it possible to visually recognize the image in the blind spot area D generated as described above. The blind spot assisting device 100 is arranged on the right pillar 50 of the pillars 50 and 60 via a holder member (not shown).
　なお、フロントガラス２０の端部には、図１に示すように、黒色のセラミックからなる遮光部２１，２２が印刷等により形成されていることが一般的である。右側のピラー５０に近接した遮光部２１によっても若干の死角が生じるが、死角補助装置１００によれば、このように生じる死角の像も視認可能となる。以下では、説明の理解を容易にするため、遮光部２１によって生じる死角は、ピラー５０によって生じる死角に含まれるものとする。 In addition, as shown in FIG. 1, it is common that the light shielding parts 21 and 22 which consist of black ceramics are formed in the edge part of the windshield 20 by printing etc. As shown in FIG. Although some blind spots are also generated by the light shielding portion 21 close to the right pillar 50, the blind spot assisting device 100 can also visually recognize the resulting blind spot image. Hereinafter, in order to facilitate understanding of the description, it is assumed that the blind spot generated by the light shielding unit 21 is included in the blind spot generated by the pillar 50.
　死角補助装置１００は、図２～図８に示すように、反射部１１０と、ルーバー１２０と、支持体１３０と、可動部材１４０と、を備える。 The blind spot assisting device 100 includes a reflecting portion 110, a louver 120, a support 130, and a movable member 140, as shown in FIGS.
（反射部１１０）
　反射部１１０は、互いに対向する第１ミラー１１１と第２ミラー１１２という、一対の（二枚の）平面ミラーから構成されている。第１ミラー１１１と第２ミラー１１２とは、互いに向かい合う面が平行となるように、図示しない筐体（前記のホルダ部材と一体でも別体でもよい）に固定され、配置されている。第１ミラー１１１と第２ミラー１１２とは、図２等に示すように、概ね水平方向に段違い状となるように配置される。 (Reflecting part 110)
The reflection unit 110 includes a pair of (two) plane mirrors, a first mirror 111 and a second mirror 112 that face each other. The first mirror 111 and the second mirror 112 are fixed and arranged in a housing (not shown) (which may be integral with or separate from the holder member) so that the surfaces facing each other are parallel to each other. As shown in FIG. 2 and the like, the first mirror 111 and the second mirror 112 are arranged so as to be substantially stepped in the horizontal direction.
　なお、一対のミラーは、互いに対向配置されるものであれば、完全な平行に配置されていなくともよい。また、一対のミラーの少なくとも一方は、平面ミラーでなく曲面ミラーであってもよい。 It should be noted that the pair of mirrors need not be arranged completely in parallel as long as they are arranged to face each other. Further, at least one of the pair of mirrors may be a curved mirror instead of a plane mirror.
　第１ミラー１１１は、入射光の一部を反射させて他の一部を透過させる。第１ミラー１１１は、第２ミラー１１２よりも視認者側に配置され、例えばポリエチレンテレフタレート、ポリカーボネート、ポリエチレン、アクリル等の透光性の樹脂材料からなる基材の表面にアルミなどの金属を蒸着させることにより、所望の反射率を有するように反射率調整層を形成してなる。反射率調整層の厚さや種類などにより、反射率（透過率）が調整される。例えば、第１ミラー１１１における透過光と反射光の光量比は、透過光：反射光＝１：９である。なお、第１ミラー１１１は、基材の表面に誘電体多層膜をコーティングして形成されてもよい。 The first mirror 111 reflects part of the incident light and transmits the other part. The first mirror 111 is disposed closer to the viewer than the second mirror 112, and deposits a metal such as aluminum on the surface of a base material made of a translucent resin material such as polyethylene terephthalate, polycarbonate, polyethylene, or acrylic. Thus, the reflectance adjustment layer is formed so as to have a desired reflectance. The reflectance (transmittance) is adjusted depending on the thickness and type of the reflectance adjusting layer. For example, the light quantity ratio between the transmitted light and the reflected light in the first mirror 111 is transmitted light: reflected light = 1: 9. The first mirror 111 may be formed by coating the surface of the base material with a dielectric multilayer film.
　第２ミラー１１２は、第１ミラー１１１で反射した光を第１ミラー１１１に向けて反射させる。第２ミラー１１２は、例えば、上述の透光性樹脂材料からなる基材の表面にアルミなどの金属を蒸着させてなる、平面アルミ蒸着ミラーである。 The second mirror 112 reflects the light reflected by the first mirror 111 toward the first mirror 111. The second mirror 112 is, for example, a planar aluminum vapor deposition mirror formed by vapor-depositing a metal such as aluminum on the surface of a base material made of the above-described translucent resin material.
　第１ミラー１１１と第２ミラー１１２とは、反射部１１０において光Ｌが反射を繰り返しながら進む方向（以下、進行方向Ｆという。図３参照）に対して、垂直方向の幅が反射部１１０における光Ｌの進行方向に向かって徐々に小さくなるように、略楔状に形成されている。これは、視認者の視野範囲から外れる不要箇所を除去して小型化及び軽量化を図るためである。また、第１ミラー１１１と第２ミラー１１２とは、互いの平面形状が略相似となるように形成されている。 The first mirror 111 and the second mirror 112 have a width in the vertical direction with respect to the direction in which the light L travels while being repeatedly reflected by the reflecting unit 110 (hereinafter referred to as the traveling direction F; see FIG. 3). It is formed in a substantially wedge shape so that it gradually decreases in the traveling direction of the light L. This is to reduce the size and weight by removing unnecessary portions that are out of the visual field range of the viewer. The first mirror 111 and the second mirror 112 are formed so that their planar shapes are substantially similar to each other.
　また、第１ミラー１１１の入射側端部（入射側の側辺）Ｅ１０と、第２ミラー１１２の入射側端部（入射側の側辺）Ｅ１１とは、フロントガラス２０のガラス面に沿って傾斜している。これは、フロントガラス２０のガラス面に近接して配置可能とするためである。 Further, the incident side end (incident side side) E10 of the first mirror 111 and the incident side end (incident side side) E11 of the second mirror 112 are along the glass surface of the windshield 20. Inclined. This is because it can be arranged close to the glass surface of the windshield 20.
　ここで、図２を参照して、反射部１１０の作用について説明する。視点（アイポイント）２は、視認者が車両１の運転席に着座した状態における視点を示している。 Here, with reference to FIG. 2, the operation of the reflection unit 110 will be described. A viewpoint (eye point) 2 indicates the viewpoint in a state where the viewer is seated in the driver's seat of the vehicle 1.
　視認者（視点２）の前方視界には、ピラー５０によって遮られる死角領域Ｄが生じる。したがって、視点２からは死角領域Ｄに存在する物体Ｍを直接視認することができない。
　一方、物体Ｍを表す光Ｌは、反射部１１０に入射し、反射部１１０の間で反射を繰り返しつつ進行する。このように進行する光Ｌの一部は第１ミラー１１１を透過して、反射部１１０から射出され、視点２に達する。これにより、視点２からは、第２ミラー１１２に映る物体Ｍの像を第１ミラー１１１越しに視認可能となる。 In the front view of the viewer (viewpoint 2), a blind spot area D that is blocked by the pillar 50 is generated. Accordingly, the object M present in the blind spot area D cannot be directly viewed from the viewpoint 2.
On the other hand, the light L representing the object M enters the reflection unit 110 and travels while being repeatedly reflected between the reflection units 110. A part of the light L traveling in this way passes through the first mirror 111 and is emitted from the reflection unit 110 to reach the viewpoint 2. Thereby, from the viewpoint 2, the image of the object M reflected on the second mirror 112 can be visually recognized through the first mirror 111.
　なお、光Ｌは反射部１１０の間で反射を繰り返すので、光Ｌが第１ミラー１１１にｎ回入射した場合、物体Ｍの像を示すｎ個の光Ｌが１つの反射部１１０から射出される。すなわち、反射部１１０からは、視認者から見た左右方向に概ね沿って、ｎ個の物体Ｍの像を示す光Ｌが射出されることになる。したがって、視認者は左右方向の広い範囲で物体Ｍの像を視認することができる。
　また、死角領域Ｄのうち、ピラー５０の背面側の僅かな領域（図２でハッチングを付した領域）における像については、反射部１１０によって映すことができない。しかし、死角領域Ｄにおいて、そのような領域以外のほとんどの像は反射部１１０によって視認可能となる。 Since the light L is repeatedly reflected between the reflecting portions 110, when the light L is incident n times on the first mirror 111, n light L indicating an image of the object M is emitted from one reflecting portion 110. The That is, the light L indicating the image of the n objects M is emitted from the reflecting portion 110 substantially along the left-right direction viewed from the viewer. Therefore, the viewer can view the image of the object M in a wide range in the left-right direction.
Further, in the blind spot area D, an image in a slight area on the back side of the pillar 50 (area hatched in FIG. 2) cannot be reflected by the reflection unit 110. However, in the blind spot area D, most of the images other than such areas are visible by the reflection unit 110.
（ルーバー１２０）
　ルーバー１２０は、第１ミラー１１１の視認者側に設けられる非透光性部材であり、例えば黒色の合成樹脂材料からなる。ルーバー１２０は、図４などに示すように、視認者側から第１ミラー１１１に所定の角度で入射する光を遮る、複数の遮光板１２１～１２６を有する。 (Louvre 120)
The louver 120 is a non-translucent member provided on the viewer side of the first mirror 111, and is made of, for example, a black synthetic resin material. As shown in FIG. 4 and the like, the louver 120 includes a plurality of light shielding plates 121 to 126 that shield light incident on the first mirror 111 from the viewer side at a predetermined angle.
　遮光板１２１～１２６は、図５に平面視で示すように、第１ミラー１１１が延びる方向に沿って所定の間隔を空けて設けられている。また、遮光板１２１～１２６は、それぞれ、後述する支持体１３０（図６、図７参照）に支持される。そして、遮光板１２１～１２６の各々は、後述するように第１ミラー１１１に対する傾斜角度が可変となっており、使用環境（例えば、ユーザ毎の体格の違いや、ユーザの姿勢や位置など）に応じて調整可能となっている。 The light shielding plates 121 to 126 are provided at predetermined intervals along the direction in which the first mirror 111 extends, as shown in a plan view in FIG. Further, each of the light shielding plates 121 to 126 is supported by a support 130 (see FIGS. 6 and 7) described later. Each of the light shielding plates 121 to 126 has a variable inclination angle with respect to the first mirror 111, as will be described later, so that the usage environment (for example, differences in physique among users, user postures and positions, etc.) can be used. It can be adjusted accordingly.
　以下では、遮光板１２１～１２６が、第１ミラー１１１と略平行となっている状態をルーバー１２０の「閉状態」（図９（ａ）参照）と言い、当該閉状態以外の状態を「開状態」（図９（ｂ）、（ｃ）参照）と言う。 Hereinafter, a state in which the light shielding plates 121 to 126 are substantially parallel to the first mirror 111 is referred to as a “closed state” of the louver 120 (see FIG. 9A), and a state other than the closed state is referred to as “open”. State "(see FIGS. 9B and 9C).
　ルーバー１２０の開状態では、図４に示すように、遮光板１２１～１２６は、各々の先端が視認者側に向くように、第１ミラー１１１の視認者側の面に対して所定の角度だけ傾いた状態となる。 In the open state of the louver 120, as shown in FIG. 4, the light-shielding plates 121 to 126 have a predetermined angle with respect to the viewer-side surface of the first mirror 111 so that the front ends thereof face the viewer-side. It will be tilted.
　ここで、図４を参照して、ルーバー１２０（遮光板１２１～１２６）の作用について説明する。 Here, the operation of the louver 120 (the light shielding plates 121 to 126) will be described with reference to FIG.
　反射部１１０には、死角領域Ｄからの光Ｌ以外に、視認者（視点２）側からも外光が入射する。視認者側から反射部１１０に入射する外光のうち、第１ミラー１１１の視認者側の面の法線Ｐに対して傾いて入射する光（以下、迷光ＳＬという）は、第２ミラー１１２に映る物体Ｍの像の視認性を低下させる要因となる。というのは、迷光ＳＬは、（ｉ）第１ミラー１１１で反射して視点２に到達したり、（ｉｉ）第１ミラー１１１を透過し、第２ミラー１１２で反射後に再度第１ミラー１１１を透過して視点２に到達したり、するからである。 Outside the light L from the blind spot area D, external light is also incident on the reflector 110 from the viewer (viewpoint 2) side. Of the external light that enters the reflector 110 from the viewer side, light that is inclined with respect to the normal P of the viewer-side surface of the first mirror 111 (hereinafter referred to as stray light SL) is the second mirror 112. This is a factor that reduces the visibility of the image of the object M reflected on the screen. This is because the stray light SL (i) is reflected by the first mirror 111 and reaches the viewpoint 2, or (ii) is transmitted through the first mirror 111 and reflected by the second mirror 112. This is because it passes through and reaches the viewpoint 2.
　遮光板１２１～１２６は、このような迷光ＳＬが第１ミラー１１１に入射することを低減する。なお、遮光板１２１～１２６は、その幅が大きいほど少数で迷光ＳＬを遮ることができるが、幅を大きくしすぎると、視点２から第２ミラー１１２に映る像を見る際の視界を遮るおそれがある。このことを考慮して、遮光板１２１～１２６の個数や各々の幅は、第１ミラー１１１に入射する迷光ＳＬを効果的に遮るように、且つ、視点２から第２ミラー１１２に映る像を見る際の視界を遮らないように、適切に定めればよい。本実施形態では、６つの遮光板１２１～１２６で迷光ＳＬを遮る例を示している。なお、迷光ＳＬの全てが遮光板１２１～１２６で遮られることが好ましいが、迷光ＳＬの一部さえ遮ることができれば、死角領域Ｄの像の視認性を向上させることができる。 The light shielding plates 121 to 126 reduce the incidence of such stray light SL on the first mirror 111. The light shielding plates 121 to 126 can block the stray light SL with a smaller number as the width is larger. However, if the width is too large, there is a risk of blocking the field of view when viewing the image reflected on the second mirror 112 from the viewpoint 2. There is. In view of this, the number of light shielding plates 121 to 126 and the width of each of the light shielding plates 121 to 126 are such that the stray light SL incident on the first mirror 111 is effectively shielded and an image reflected on the second mirror 112 from the viewpoint 2 is displayed. What is necessary is just to determine appropriately so that the field of vision at the time of seeing may not be obstructed. In the present embodiment, an example in which the stray light SL is blocked by the six light blocking plates 121 to 126 is shown. Although all of the stray light SL is preferably blocked by the light shielding plates 121 to 126, the visibility of the image of the blind spot region D can be improved if even a part of the stray light SL can be blocked.
　次に、ルーバー１２０が開状態の場合における、遮光板１２１～１２６の位置及び角度について、図３及び図５を参照して説明する。 Next, the position and angle of the light shielding plates 121 to 126 when the louver 120 is in the open state will be described with reference to FIGS.
　視点２から反射部１１０に映される死角領域Ｄの像を視認しようとすると、その像以外に、下記（ｉ）～（ｉｉｉ）のように視認されることになる。
　（ｉ）第１ミラー１１１の視認者側に設けられた遮光板１２１～１２６自体が、上下方向（視認者から見ての上下方向）に沿う線状に視認される。（ｉｉ）また、第２ミラー１１２の入射側端部Ｅ１１も、それ自体が上下方向に沿う線状に視認される。（ｉｉｉ）さらには、第２ミラー１１２の入射側端部Ｅ１１の像を示す光は、反射部１１０内で反射を繰り返すことで、第２ミラー１１２上において複数の像Ｅ１２～Ｅ１４として視認され、これらの各々も上下方向に沿う線状に視認される。
　これらが別々に視認されると、死角補助装置１００の視認性が損なわれるおそれがある。 When an image of the blind spot area D projected on the reflection unit 110 from the viewpoint 2 is to be visually recognized, the image is visually recognized as (i) to (iii) below in addition to the image.
(I) The light-shielding plates 121 to 126 provided on the viewer side of the first mirror 111 are viewed in a line along the vertical direction (vertical direction as viewed from the viewer). (Ii) The incident side end E11 of the second mirror 112 is also visually recognized as a line along the vertical direction. (Iii) Furthermore, the light indicating the image of the incident side end E11 of the second mirror 112 is repeatedly reflected in the reflecting unit 110, so that it is visually recognized as a plurality of images E12 to E14 on the second mirror 112, Each of these is also visually recognized as a line along the vertical direction.
If these are viewed separately, the visibility of the blind spot assisting device 100 may be impaired.
　そこで、本実施形態では、図５に示すように、基準視点位置として予め定められる視点２から見て、第２ミラー１１２の入射側端部Ｅ１１と、像Ｅ１２～Ｅ１４（第２ミラー１１２の入射側端部Ｅ１１の反射像）との各々に重なるように、遮光板１２３～１２６を配置することで、視認性の低下を防止している。
　具体的には、遮光板１２３～１２６の各々を、第２ミラー１１２の入射側端部Ｅ１１（入射側の側辺）と平行に延びるように設ける（図３参照）と共に、図５に示すような角度で配置する。 Therefore, in the present embodiment, as shown in FIG. 5, when viewed from the viewpoint 2 that is predetermined as the reference viewpoint position, the incident side end E11 of the second mirror 112 and the images E12 to E14 (incident of the second mirror 112) The light shielding plates 123 to 126 are arranged so as to overlap each of the reflection images of the side end portion E11), thereby preventing the visibility from being deteriorated.
Specifically, each of the light shielding plates 123 to 126 is provided so as to extend in parallel with the incident side end E11 (side of the incident side) of the second mirror 112 (see FIG. 3), as shown in FIG. Arrange at a proper angle.
　遮光板１２３については、視点２から見て入射側端部Ｅ１１と重なるように、視点２と入射側端部Ｅ１１とを結ぶ直線Ｓ１に沿う角度で配置する。
　なお、直線Ｓ１は、視点２から見て第１ミラー１１１を介して背景を視認する領域（１回目）と、第１ミラー１１１、第２ミラー１１２の順で反射されて再度（２回目）第１ミラー１１１に入射する像を視認する領域との境界となる。 The light shielding plate 123 is arranged at an angle along the straight line S1 connecting the viewpoint 2 and the incident side end E11 so as to overlap with the incident side end E11 when viewed from the viewpoint 2.
The straight line S1 is reflected in the order of the first mirror 111 and the second mirror 112 in the order of viewing the background through the first mirror 111 when viewed from the viewpoint 2, and the second mirror 112 again (second time). It becomes a boundary with the area | region which visually recognizes the image which injects into 1 mirror 111. FIG.
　遮光板１２４については、視点２から見て第２ミラー１１２に映り込む像Ｅ１２と重なるように、視点２と像Ｅ１２の位置とを結ぶ直線Ｓ２に沿う角度で配置する。
　なお、第１ミラー１１１と第２ミラー１１２との間隔を「間隔Ａ」とすると（図５参照）、直線Ｓ２は、入射側端部Ｅ１１と、入射側端部Ｅ１１から第２ミラー１１２の背面の法線方向に「２×Ａ」だけ移動した点Ｅ２１とを結ぶ直線となる。また、直線Ｓ２は、２回目に第１ミラー１１１に入射する像を視認する領域とさらに第１ミラー１１１、第２ミラー１１２の順で反射されて再度（３回目）第１ミラー１１１に入射する像を視認する領域との境界となる。 The light shielding plate 124 is arranged at an angle along the straight line S2 connecting the viewpoint 2 and the position of the image E12 so as to overlap the image E12 reflected on the second mirror 112 when viewed from the viewpoint 2.
If the interval between the first mirror 111 and the second mirror 112 is “interval A” (see FIG. 5), the straight line S2 is the incident side end E11 and the back side of the second mirror 112 from the incident side end E11. This is a straight line connecting the point E21 moved by “2 × A” in the normal direction. In addition, the straight line S2 is reflected in the order in which the image that is incident on the first mirror 111 for the second time is visually recognized, and further in the order of the first mirror 111 and the second mirror 112, and is incident on the first mirror 111 again (third time). It becomes a boundary with the area where the image is viewed.
　遮光板１２５については、視点２から見て第２ミラー１１２に映り込む像Ｅ１３と重なるように、視点２と像Ｅ１３の位置とを結ぶ直線Ｓ３に沿う角度で配置する。
　なお、直線Ｓ３は、入射側端部Ｅ１１と、入射側端部Ｅ１１から第２ミラー１１２の背面の法線方向に「４×Ａ」だけ移動した点Ｅ３１とを結ぶ直線となる。また、直線Ｓ３は、３回目に第１ミラー１１１に入射する像を視認する領域とさらに第１ミラー１１１、第２ミラー１１２の順で反射されて再度（４回目）第１ミラー１１１に入射する像を視認する領域との境界となる。 The light shielding plate 125 is arranged at an angle along the straight line S3 connecting the viewpoint 2 and the position of the image E13 so as to overlap the image E13 reflected on the second mirror 112 when viewed from the viewpoint 2.
The straight line S3 is a straight line connecting the incident side end E11 and the point E31 moved from the incident side end E11 by “4 × A” in the normal direction of the back surface of the second mirror 112. In addition, the straight line S3 is reflected in the order of the first mirror 111 and the second mirror 112 in the order of viewing the image incident on the first mirror 111 for the third time, and then enters the first mirror 111 again (fourth time). It becomes a boundary with the area where the image is viewed.
　遮光板１２６については、視点２から見て第２ミラー１１２に映り込む像Ｅ１４と重なるように、視点２と像Ｅ１４の位置とを結ぶ直線Ｓ４に沿う角度で配置する。
　なお、直線Ｓ４は、入射側端部Ｅ１１と、入射側端部Ｅ１１から第２ミラー１１２の背面の法線方向に「６×Ａ」だけ移動した点Ｅ４１とを結ぶ直線となる。また、直線Ｓ４は、４回目に第１ミラー１１１に入射する像を視認する領域とさらに第１ミラー１１１、第２ミラー１１２の順で反射されて再度（５回目）第１ミラー１１１に入射する像を視認する領域との境界となる。 The light shielding plate 126 is disposed at an angle along a straight line S4 connecting the viewpoint 2 and the position of the image E14 so as to overlap the image E14 reflected on the second mirror 112 when viewed from the viewpoint 2.
The straight line S4 is a straight line connecting the incident side end E11 and the point E41 moved from the incident side end E11 by “6 × A” in the normal direction of the back surface of the second mirror 112. In addition, the straight line S4 is reflected in the order of the first mirror 111 and the second mirror 112 in the order of viewing the image incident on the first mirror 111 for the fourth time, and is incident on the first mirror 111 again (fifth time). It becomes a boundary with the area where the image is viewed.
　また、視点２から反射部１１０に映される死角領域Ｄの像を視認しようとすると、第２ミラー１１２の入射側端部Ｅ１１だけでなく、第１ミラー１１１の入射側端部Ｅ１０も、それ自体が上下方向に沿う線状に視認される。 Further, when an image of the blind spot area D projected on the reflecting portion 110 is viewed from the viewpoint 2, not only the incident side end E11 of the second mirror 112 but also the incident side end E10 of the first mirror 111 It is visually recognized as a line along the vertical direction.
　そこで、本実施形態では、図５に示すように、遮光板１２１を基準視点位置として予め定められる視点２から見て、第１ミラー１１１の入射側端部Ｅ１０と重なるように配置することで、視認性の低下を防止している。
　具体的には、遮光板１２１を、第１ミラー１１１の入射側端部Ｅ１０（入射側の側辺）と重なるように設けると共に、図５に示す角度で配置する。つまり、遮光板１２１を、視点２から見て入射側端部Ｅ１０と重なるように、視点２と入射側端部Ｅ１０とを結ぶ直線Ｓ０に沿う角度で配置する。なお、直線Ｓ０は、視点２から見て直接背景を視認する領域と第１ミラー１１１を介して背景を視認する領域との境界となる。 Therefore, in the present embodiment, as shown in FIG. 5, the light shielding plate 121 is disposed so as to overlap the incident side end E10 of the first mirror 111 when viewed from the viewpoint 2 that is predetermined as the reference viewpoint position. The visibility is prevented from decreasing.
Specifically, the light shielding plate 121 is provided so as to overlap the incident side end E10 (incident side side) of the first mirror 111, and is arranged at an angle shown in FIG. That is, the light shielding plate 121 is disposed at an angle along the straight line S0 connecting the viewpoint 2 and the incident side end E10 so as to overlap the incident side end E10 when viewed from the viewpoint 2. The straight line S <b> 0 serves as a boundary between a region in which the background is visually recognized as viewed from the viewpoint 2 and a region in which the background is visually recognized via the first mirror 111.
　遮光板１２２は、遮光板１２１の長さを低減するために遮光板１２１と遮光板１２３との間に設けられる。遮光板１２２の第１ミラー１１１の平面に対する角度θ２は、一例として、遮光板１２１の第１ミラー１１１の平面に対する角度θ１よりも大きく、視点２に向く角度としている。 The light shielding plate 122 is provided between the light shielding plate 121 and the light shielding plate 123 in order to reduce the length of the light shielding plate 121. As an example, the angle θ2 of the light shielding plate 122 with respect to the plane of the first mirror 111 is larger than the angle θ1 of the light shielding plate 121 with respect to the plane of the first mirror 111 and is an angle toward the viewpoint 2.
　このように、遮光板１２１～１２６を配置すると、遮光板１２１～１２６の第１ミラー１１１の平面に対する角度θ１～θ６が、反射部１１０における光Ｌの進行方向に沿って徐々に（段階的に１つずつ）大きくなるように設けられることとなる（θ１＜θ２＜θ３＜θ４＜θ５＜θ６）。 As described above, when the light shielding plates 121 to 126 are arranged, the angles θ1 to θ6 of the light shielding plates 121 to 126 with respect to the plane of the first mirror 111 gradually (in a stepwise manner) along the traveling direction of the light L in the reflection unit 110. (One by one) provided to be larger (θ1 <θ2 <θ3 <θ4 <θ5 <θ6).
　なお、角度θ２を角度θ１と同様とし（θ１＝θ２）、複数の遮光板１２１～１２６は、第１ミラー１１１の平面に対する角度θ１～θ６が、反射部１１０における光Ｌの入射側から射出側に向かって、ある程度段階的に大きくなるように設けられてなるものであってもよい（θ１＝θ２＜θ３＜θ４＜θ５＜θ６）。 Note that the angle θ2 is the same as the angle θ1 (θ1 = θ2), and the plurality of light shielding plates 121 to 126 have the angles θ1 to θ6 with respect to the plane of the first mirror 111 such that the angles L1 to θ6 on the reflecting portion 110 It may be provided so as to increase to a certain degree toward the direction (θ1 = θ2 <θ3 <θ4 <θ5 <θ6).
　遮光板１２１～１２６は、それぞれ、第１ミラー１１１側に設定された回転軸線（図６の点線参照）を中心に独立して回転可能に、支持体１３０に支持されている。 The light shielding plates 121 to 126 are supported by the support 130 so as to be independently rotatable around a rotation axis set on the first mirror 111 side (see the dotted line in FIG. 6).
　遮光板１２１～１２６が支持体１３０へ支持される構造は同様であるため、以下では、主に遮光板１２３について説明する。また、遮光板１２３の回転軸線を、図６、図７に示すように「回転軸線ＡＸ」とする。 Since the structure in which the light shielding plates 121 to 126 are supported on the support 130 is the same, the light shielding plate 123 will be mainly described below. Further, the rotation axis of the light shielding plate 123 is assumed to be a “rotation axis AX” as shown in FIGS.
　図６は、図５に示す平面視から視点２側にやや傾いて見た場合における遮光板１２２～１２５などの概略斜視図である。また、図７は、遮光板１２３の傾斜方向に沿って切った場合の、遮光板１２３、支持体１３０及び可動部材１４０の概略断面図である。なお、遮光板１２３については、見易さを考慮して断面を表すハッチングは省略している。 FIG. 6 is a schematic perspective view of the light shielding plates 122 to 125 and the like when viewed slightly tilted toward the viewpoint 2 side from the plan view shown in FIG. FIG. 7 is a schematic cross-sectional view of the light shielding plate 123, the support 130, and the movable member 140 when cut along the inclination direction of the light shielding plate 123. In addition, about the light shielding plate 123, the hatching showing a cross section is abbreviate | omitted in consideration of legibility.
　遮光板１２３は、支持体１３０に対して回転可能に設けられていることで第１ミラー１１１に対する傾斜角度が可変となっており、当該回転の回転軸線ＡＸに沿う第１軸部１２７と、第２軸部１２８と、を有する。 Since the light shielding plate 123 is provided so as to be rotatable with respect to the support 130, the inclination angle with respect to the first mirror 111 is variable, and the first shaft portion 127 along the rotation axis AX of the rotation, A biaxial portion 128.
　第１軸部１２７は、遮光板１２３の第１ミラー１１１側に位置し、図７に示すように、遮光板１２３の上下各々に突出して、一対設けられている。 The first shaft portion 127 is located on the first mirror 111 side of the light shielding plate 123, and as shown in FIG.
　第２軸部１２８は、第１軸部１２７と離れて位置し（回転軸線ＡＸの径方向に離れて位置し）、遮光板１２３の上下各々に突出して、一対設けられている。 The second shaft portion 128 is located apart from the first shaft portion 127 (positioned away from the radial direction of the rotation axis AX), and is provided in a pair so as to protrude above and below the light shielding plate 123.
　例えば、一対の第１軸部１２７と、一対の第２軸部１２８とは、共に、遮光板１２３と一体に形成されている。なお、第１軸部１２７と第２軸部１２８との少なくとも一方は、遮光板１２３に形成された穴（上下方向に延びる穴）に挿入された棒であってもよい。 For example, the pair of first shaft portions 127 and the pair of second shaft portions 128 are both formed integrally with the light shielding plate 123. Note that at least one of the first shaft portion 127 and the second shaft portion 128 may be a rod inserted into a hole (a hole extending in the vertical direction) formed in the light shielding plate 123.
　遮光板１２３以外についても同様に、遮光板１枚につき、一対の第１軸部１２７と、一対の第２軸部１２８とが設けられている。 Similarly, except for the light shielding plate 123, a pair of first shaft portions 127 and a pair of second shaft portions 128 are provided for each light shielding plate.
（支持体１３０）
　支持体１３０は、例えば、第１ミラー１１１及び第２ミラー１１２を保持する筐体（図示せず）と一体に形成される。なお、支持体１３０は、当該筐体と別体であってもよい。 (Support 130)
The support 130 is formed integrally with a housing (not shown) that holds the first mirror 111 and the second mirror 112, for example. The support body 130 may be a separate body from the casing.
　支持体１３０は、図７に示すように、ルーバー１２０（図７では遮光板１２３のみ示した）の下側に位置する下板部１３１と、上側に位置する上板部１３２と、を有する。 As shown in FIG. 7, the support 130 has a lower plate portion 131 positioned on the lower side of the louver 120 (only the light shielding plate 123 is shown in FIG. 7) and an upper plate portion 132 positioned on the upper side.
　下板部１３１には、一対の第１軸部１２７の一方を受ける軸受部１３１ａと、一対の第２軸部１２８の一方が挿入される規制部１３１ｂとが形成されている。
　上板部１３２には、一対の第１軸部１２７の他方を受ける軸受部１３２ａと、一対の第２軸部１２８の他方が挿入される規制部１３２ｂとが形成されている。 The lower plate portion 131 is formed with a bearing portion 131a that receives one of the pair of first shaft portions 127 and a restriction portion 131b into which one of the pair of second shaft portions 128 is inserted.
The upper plate portion 132 is formed with a bearing portion 132a that receives the other of the pair of first shaft portions 127 and a restriction portion 132b into which the other of the pair of second shaft portions 128 is inserted.
　つまり、支持体１３０には、一対の軸受部１３１ａ，１３２ａと、一対の規制部１３１ｂ，１３２ｂとが形成されている。なお、平面視において（図７に示す矢視Ｇにおいて）、軸受部１３１ａと軸受部１３２ａとは同様の形状をなし、規制部１３１ｂと規制部１３２ｂとは同様の形状をなす。そのため、以下では、主に軸受部１３１ａと規制部１３１ｂについて説明する。 That is, the support 130 is formed with a pair of bearing portions 131a and 132a and a pair of restricting portions 131b and 132b. In a plan view (in the arrow G shown in FIG. 7), the bearing portion 131a and the bearing portion 132a have the same shape, and the restricting portion 131b and the restricting portion 132b have the same shape. Therefore, below, the bearing part 131a and the control part 131b are mainly demonstrated.
　軸受部１３１ａは、第１軸部１２７を回転可能に軸支するものであり、図７に示すように、下板部１３１を回転軸線ＡＸに沿って貫通する貫通孔として形成されている。なお、軸受部１３１ａは、有底孔であってもよい。 The bearing portion 131a pivotally supports the first shaft portion 127 and is formed as a through-hole penetrating the lower plate portion 131 along the rotation axis AX as shown in FIG. The bearing portion 131a may be a bottomed hole.
　規制部１３１ｂは、第２軸部１２８が挿入されると共に、遮光板１２３の回転に伴って移動する第２軸部１２８の可動範囲を規制するものである。規制部１３１ｂは、下板部１３１を貫通する孔として形成され（図７参照）、平面視では、回転軸線ＡＸを中心とした円弧状に形成されている（図８参照）。なお、規制部１３１ｂは、有底孔（円弧状の溝）として形成されてもよい。 The regulating portion 131b regulates the movable range of the second shaft portion 128 that is moved along with the rotation of the light shielding plate 123 while the second shaft portion 128 is inserted. The restricting portion 131b is formed as a hole penetrating the lower plate portion 131 (see FIG. 7), and is formed in an arc shape around the rotation axis AX in a plan view (see FIG. 8). Note that the restricting portion 131b may be formed as a bottomed hole (arc-shaped groove).
　支持体１３０の上板部１３２には、図７に示すように、可動部材１４０を収容する収容部１３３が設けられている。収容部１３３は、例えば、上板部１３２の上面側に設けられ、可動部材１４０をスライド移動可能に収容する。 As shown in FIG. 7, the upper plate portion 132 of the support 130 is provided with a housing portion 133 that houses the movable member 140. The accommodating part 133 is provided on the upper surface side of the upper plate part 132, for example, and accommodates the movable member 140 so as to be slidable.
（可動部材１４０）
　可動部材１４０は、例えばユーザの手動操作（以下、スライド操作）によって、支持体１３０の収容部１３３内をスライド可能に設けられている。この実施形態では、可動部材１４０は、図９（ｂ）、（ｃ）に示すスライド方向Ｓ（順方向だけでなく逆方向も含む。また図３に示す進行方向Ｆと略一致）に沿って移動可能となっている。可動部材１４０は、板状の部材であり、例えば、平面視で上板部１３２よりも一回り小さく形成されている。 (Movable member 140)
The movable member 140 is provided so as to be slidable within the accommodating portion 133 of the support 130 by, for example, a manual operation (hereinafter referred to as a slide operation) by a user. In this embodiment, the movable member 140 is along the sliding direction S (including not only the forward direction but also the reverse direction shown in FIGS. 9B and 9C, and substantially coincides with the traveling direction F shown in FIG. 3). It is movable. The movable member 140 is a plate-like member, and is formed, for example, slightly smaller than the upper plate portion 132 in plan view.
　可動部材１４０は、第２軸部１２８の一部が挿入される挿入部１４１を有する。この実施形態では、挿入部１４１は、貫通孔として形成されている。図７に示すように、一方の（上側の）第２軸部１２８は、上板部１３２の規制部１３２ｂと、可動部材１４０の挿入部１４１とを通過して、その上端が可動部材１４０の上面から露出するような格好となる。
　なお、挿入部１４１が有底孔として形成され（つまり溝形状）、第２軸部１２８の上端が、可動部材１４０の上面から露出しないようにしてもよい。 The movable member 140 has an insertion portion 141 into which a part of the second shaft portion 128 is inserted. In this embodiment, the insertion portion 141 is formed as a through hole. As shown in FIG. 7, one (upper) second shaft portion 128 passes through the restriction portion 132 b of the upper plate portion 132 and the insertion portion 141 of the movable member 140, and the upper end of the second shaft portion 128 of the movable member 140. It looks like it is exposed from the top.
The insertion portion 141 may be formed as a bottomed hole (that is, a groove shape) so that the upper end of the second shaft portion 128 is not exposed from the upper surface of the movable member 140.
　挿入部１４１は、遮光板１２１～１２６の各々に対応して複数（遮光板と同数）設けられている。なお、１枚の遮光板と１つの挿入部１４１との関係は同様なので、以下では、主に、図８（ａ）に示した任意の遮光板（遮光板１２３）に着目して、挿入部１４１の形状について説明する。 A plurality of insertion portions 141 are provided corresponding to each of the light shielding plates 121 to 126 (the same number as the light shielding plates). Since the relationship between one light shielding plate and one insertion portion 141 is the same, the insertion portion will be mainly focused on the arbitrary light shielding plate (light shielding plate 123) shown in FIG. The shape 141 will be described.
　図８（ａ）は、図７に示した矢視Ｇから見た場合における支持体１３０の上板部１３２と、一部の遮光板（遮光板１２１～１２３）との関係を表した概略平面図である。図８（ｂ）は、同じく矢視Ｇから見た場合における可動部材１４０の概略平面図である。 FIG. 8A is a schematic plan view showing the relationship between the upper plate portion 132 of the support 130 and a part of the light shielding plates (light shielding plates 121 to 123) when viewed from the arrow G shown in FIG. FIG. FIG. 8B is a schematic plan view of the movable member 140 when viewed from the same direction G.
　図８（ａ）と図８（ｂ）を比較してわかるように、挿入部１４１は、円弧状に形成された規制部１３２ｂと交差する方向に延びるように形成されている。なお、図示しないが、同様に円弧状に形成された規制部１３１ｂとも挿入部１４１は交差する。 As can be seen by comparing FIG. 8A and FIG. 8B, the insertion portion 141 is formed to extend in a direction intersecting with the restricting portion 132b formed in an arc shape. Although not shown, the insertion portion 141 also intersects with a restriction portion 131b similarly formed in an arc shape.
　なお、図８（ｂ）では、挿入部１４１を直線的に表し、また遮光板１２１～１２３の各々に対応する挿入部１４１を同様な形状で表しているが、これらは簡易的に表したものである。実際は、挿入部１４１は直線的に延びるものに限られず、また、複数の挿入部１４１は各々異なる形状で形成されている。これについては、次に述べる動作説明において、併せて説明する。 In FIG. 8B, the insertion portion 141 is represented linearly and the insertion portion 141 corresponding to each of the light shielding plates 121 to 123 is represented in the same shape, but these are simply represented. It is. Actually, the insertion portion 141 is not limited to a linearly extending portion, and the plurality of insertion portions 141 are formed in different shapes. This will be described together in the following description of the operation.
　ここからは、図９（ａ）～（ｃ）と、図５を参照して、可動部材１４０の移動による遮光板１２１～１２６の回転動作（角度調整）と、挿入部１４１の形状について説明する。 From here, with reference to FIGS. 9A to 9C and FIG. 5, the rotational operation (angle adjustment) of the light shielding plates 121 to 126 by the movement of the movable member 140 and the shape of the insertion portion 141 will be described. .
　なお、図９（ａ）～（ｃ）は、図８（ａ）、（ｂ）と対応した図であり、見易さのため可動部材１４０を破線で示したものである。また、可動部材１４０の移動による遮光板１２１～１２６の概略動作は同様であるため、ここでも遮光板１２３に着目して説明する。また、以下に図９を用いて説明する際の上下左右方向とは、特に断りが無い場合は、同図における上下左右方向を示すものとする。 9A to 9C are diagrams corresponding to FIGS. 8A and 8B, and the movable member 140 is indicated by a broken line for easy viewing. Further, since the general operation of the light shielding plates 121 to 126 by the movement of the movable member 140 is the same, the description will be given here also focusing on the light shielding plate 123. In addition, the vertical and horizontal directions in the following description with reference to FIG. 9 indicate the vertical and horizontal directions in the figure unless otherwise specified.
　図９（ａ）は、ルーバー１２０の閉状態を示す図である。閉状態においては、上板部１３２に対して、可動部材１４０は下側（死角補助装置１００に対してユーザ側に相当）にずれた状態に位置している。閉状態では、遮光板１２３の第２軸部１２８は、規制部１３２ｂの右端に位置し、且つ、可動部材１４０の挿入部１４１の右端に位置している。 FIG. 9A is a diagram showing the closed state of the louver 120. In the closed state, the movable member 140 is positioned downward with respect to the upper plate portion 132 (corresponding to the user side with respect to the blind spot assisting device 100). In the closed state, the second shaft portion 128 of the light shielding plate 123 is located at the right end of the restricting portion 132 b and is located at the right end of the insertion portion 141 of the movable member 140.
　なお、一対の第２軸部１２８のうち他方の第２軸部１２８については、同様に、下板部１３１の規制部１３１ｂの右端に位置する。下板部１３１に対応した第２軸部１２８の挙動は、上板部１３２に対応した第２軸部１２８の挙動と同様であるため、以下では説明を割愛する。 In addition, about the other 2nd axial part 128 among a pair of 2nd axial parts 128, it is located in the right end of the control part 131b of the lower board part 131 similarly. Since the behavior of the second shaft portion 128 corresponding to the lower plate portion 131 is the same as the behavior of the second shaft portion 128 corresponding to the upper plate portion 132, description thereof will be omitted below.
　図９（ａ）の閉状態から、可動部材１４０がスライド方向Ｓ（上方向）にスライド操作（例えば、ユーザが可動部材１４０を前方に押し出す操作）されると、挿入部１４１に挿入された第２軸部１２８が、図９（ｂ）、（ｃ）に順に示すように、規制部１３２ｂに沿って左上へと移動する。これにより、遮光板１２３が第１軸部１２７を中心に、図９における時計周りに回転する。 When the movable member 140 is slid in the sliding direction S (upward) from the closed state in FIG. 9A (for example, the user pushes the movable member 140 forward), the first inserted into the insertion unit 141 is the first. As shown in FIG. 9B and FIG. 9C in order, the biaxial portion 128 moves to the upper left along the restricting portion 132b. Accordingly, the light shielding plate 123 rotates around the first shaft portion 127 in the clockwise direction in FIG.
　このような可動部材１４０の移動に伴い、遮光板１２３と同様にして、図９に示す遮光板１２１，１２２や、その他の遮光板１２４～１２６も一度に回転する。
　反対に、可動部材１４０がスライド方向Ｓ（下方向）にスライド操作（例えば、ユーザが可動部材１４０を引っ張る操作）されると、遮光板１２１～１２６が一度に反時計周りに回転する。 As the movable member 140 moves, the light shielding plates 121 and 122 shown in FIG. 9 and the other light shielding plates 124 to 126 rotate at the same time as the light shielding plate 123.
Conversely, when the movable member 140 is slid in the sliding direction S (downward) (for example, an operation in which the user pulls the movable member 140), the light shielding plates 121 to 126 rotate counterclockwise at a time.
　概ね上記のように遮光板１２１～１２６は回転動作するが、詳細には、死角補助装置１００は、可動部材１４０のスライド方向Ｓにおける移動量に対して、遮光板１２１～１２６各々の回転量が異なるように設定されている。 In general, the light shielding plates 121 to 126 rotate as described above. Specifically, the blind spot assisting device 100 has a rotational amount of each of the light shielding plates 121 to 126 with respect to the amount of movement of the movable member 140 in the sliding direction S. Are set differently.
　具体的には、図５に示すように、ルーバー１２０が開状態において遮光板１２１～１２６の各々が視点２（予め定めた想定点）に同時に向くように設定される。
　ここで、従来のように遮光板が固定されていた場合における表示の見づらさは、主に運転席の前後方向（図５の「前」「後」を付した両端矢印参照）の座席移動により視点２が前後方向に移動してしまうことで、視点２に対する遮光板の傾斜が変化してしまうことに起因する。なお、図５に示すように、第１ミラー１１１と第２ミラー１１２が沿う方向に対して、運転席に着座したユーザにとっての前後方向は斜めの関係となる（死角補助装置１００はピラー５０に配置されるため）。 Specifically, as shown in FIG. 5, when the louver 120 is in an open state, each of the light shielding plates 121 to 126 is set so as to face the viewpoint 2 (predetermined assumption point) simultaneously.
Here, when the shading plate is fixed as in the conventional case, the display difficulty is mainly due to the movement of the seat in the front-rear direction of the driver's seat (see the double-headed arrows with “front” and “rear” in FIG. 5). This is because the inclination of the light shielding plate with respect to the viewpoint 2 changes due to the viewpoint 2 moving in the front-rear direction. As shown in FIG. 5, the front-rear direction for the user seated in the driver's seat is oblique with respect to the direction along which the first mirror 111 and the second mirror 112 are aligned (the blind spot assisting device 100 is connected to the pillar 50). To be placed).
　死角補助装置１００は、図５に示す前後方向に沿う視点２の移動を遮光板１２１～１２６が同時に追うことが可能に設定される。前述の通り、遮光板１２１～１２６の第１ミラー１１１の視認者側の面に対する角度θ１～θ６は、「θ１＜θ２＜θ３＜θ４＜θ５＜θ６」という関係を満たす。これは、視点２が図５のように前後方向に移動した際（同図の白丸を参照）でも同様である。
　そのため、可動部材１４０の同一移動量に対しては、図５における上側から、遮光板１２１、遮光板１２２、・・遮光板１２６の順に、回転量が大きくなるように設定される。 The blind spot assisting device 100 is set so that the light shielding plates 121 to 126 can simultaneously follow the movement of the viewpoint 2 along the front-rear direction shown in FIG. As described above, the angles θ1 to θ6 of the light shielding plates 121 to 126 with respect to the viewer-side surface of the first mirror 111 satisfy the relationship “θ1 <θ2 <θ3 <θ4 <θ5 <θ6”. This is the same even when the viewpoint 2 moves in the front-rear direction as shown in FIG. 5 (see white circles in the figure).
Therefore, for the same movement amount of the movable member 140, the rotation amount is set to increase in the order of the light shielding plate 121, the light shielding plate 122, and the light shielding plate 126 from the upper side in FIG.
　図９（ｂ）、（ｃ）に示すように、スライド方向Ｓに沿って所定量だけ可動部材１４０が移動した場合における、遮光板１２１の回転量をＲ１、遮光板１２２の回転量をＲ２、遮光板１２３の回転量をＲ３とすると、当該所定量に対する回転量は、Ｒ１＜Ｒ２＜Ｒ３という関係を満たすことになる。 As shown in FIGS. 9B and 9C, when the movable member 140 moves along the slide direction S by a predetermined amount, the rotation amount of the light shielding plate 121 is R1, the rotation amount of the light shielding plate 122 is R2, When the rotation amount of the light shielding plate 123 is R3, the rotation amount with respect to the predetermined amount satisfies the relationship R1 <R2 <R3.
　同様な考えで、各遮光板１２１～１２６の角度変化量を個別に設定可能となる。これは各挿入部１４１の形状を、遮光板１２１～１２６毎にパターンを変えておくことで容易に実現できる。例えば挿入部１４１を急な傾斜で設ければ、一定のスライド量に対して遮光板は急に角度を変えることになり、逆に挿入部１４１を緩い傾斜で設ければルーバーの角度変化は少なくなる。これが可能になることは死角補助装置１００においては極めて重要である。既に特許文献１に記載されている通り、ルーバーが視認性に影響を及ぼす点を鑑み、個々のルーバー角度は視認者の視点に向ける等の配慮を行ってきている。この視点が移動する場合を想定しての角度調整が、この実施形態に係る死角補助装置１００の特徴の一つであるが、移動する一点（視点２の位置を想定した想定点）に各遮光板１２１～１２６を正確に向けるには、想定点と各遮光板１２１～１２６との距離の違いに応じて、遮光板１２１～１２６の角度変化量を個々に変える必要が出てくる（想定点との距離が近いほど角度変化量を大きくする必要がある）。本実施形態のように、視点２と死角補助装置１００が比較的近い距離にある場合には、遮光板１２１～１２６の角度変化量の違いはより顕著に生じる。
　そのため、この実施形態では、視点２が変化し得る位置（図５に示す前後方向に沿う線上の位置）を予測しておき、それぞれの位置における理想的な遮光板１２１～１２６各々の角度設定を、可動部材１４０の挿入部１４１の形状に反映しておく手順を踏むことにより容易に実現することができる。 Based on the same idea, the amount of change in angle of each light shielding plate 121 to 126 can be set individually. This can be easily realized by changing the pattern of each insertion portion 141 for each of the light shielding plates 121 to 126. For example, if the insertion portion 141 is provided with a steep slope, the light shielding plate will suddenly change the angle with respect to a certain slide amount. Conversely, if the insertion portion 141 is provided with a gentle slope, the angle change of the louver is small. Become. It becomes extremely important in the blind spot assisting device 100 to enable this. As already described in Patent Document 1, in consideration of the influence of the louver on the visibility, consideration has been given such that the individual louver angles are directed toward the viewer's viewpoint. The angle adjustment on the assumption that the viewpoint moves is one of the features of the blind spot assisting device 100 according to this embodiment. However, each of the light shielding points at the moving point (the assumed point assuming the position of the viewpoint 2). In order to accurately direct the plates 121 to 126, it is necessary to individually change the amount of change in the angle of the light shielding plates 121 to 126 according to the difference in distance between the assumed point and each of the light shielding plates 121 to 126 (assumed points). It is necessary to increase the amount of angle change as the distance between As in the present embodiment, when the viewpoint 2 and the blind spot assisting device 100 are at a relatively close distance, the difference in the amount of change in angle between the light shielding plates 121 to 126 occurs more significantly.
Therefore, in this embodiment, a position where the viewpoint 2 can change (position on the line along the front-rear direction shown in FIG. 5) is predicted, and the ideal angle setting of each of the light shielding plates 121 to 126 at each position is set. It can be easily realized by following the procedure reflected in the shape of the insertion portion 141 of the movable member 140.
　具体的には、可動部材１４０に遮光板１２１～１２６の各々に対応して形成された挿入部１４１は、遮光板１２１～１２６の各々が視点２に同時に向くように（前後方向に沿う視点２の移動を同時に追うように）、形成される。前記の通り、所定量の可動部材１４０の移動に対しての遮光板１２１～１２６の回転量は、それぞれ異なるため、複数（遮光板１２１～１２６と同数）の挿入部１４１は、各々異なる形状で形成される。各挿入部１４１の形状は、図５に示す前後方向に沿う線上における想定点の位置と、当該想定点を同時に追うことが可能な遮光板１２１～１２６の角度θ１～θ６と、可動部材１４０のスライド量との関数によりを定めることが可能である。このように定めると、挿入部１４１の各々は、直線的な形状に限られず、傾斜角度も適宜に異なることになる。また、挿入部１４１の形状として、可動部材１４０のスライド量に対する遮光板１２１～１２６それぞれの回転量を調整すべく曲率が徐変する曲線が含まれてもよい。 Specifically, the insertion portion 141 formed on the movable member 140 corresponding to each of the light shielding plates 121 to 126 is arranged so that each of the light shielding plates 121 to 126 faces the viewpoint 2 simultaneously (viewpoint 2 along the front-rear direction). At the same time). As described above, the rotation amounts of the light shielding plates 121 to 126 with respect to the movement of the predetermined amount of the movable member 140 are different from each other. Therefore, the plurality of insertion portions 141 (the same number as the light shielding plates 121 to 126) have different shapes. It is formed. The shape of each insertion portion 141 is such that the position of the assumed point on the line along the front-rear direction shown in FIG. 5, the angles θ1 to θ6 of the light shielding plates 121 to 126 that can simultaneously follow the assumed point, and the movable member 140 It can be determined by a function of the slide amount. If it defines in this way, each of the insertion part 141 will not be restricted to a linear shape, but an inclination angle will also differ suitably. Further, the shape of the insertion portion 141 may include a curve in which the curvature gradually changes so as to adjust the rotation amount of each of the light shielding plates 121 to 126 with respect to the sliding amount of the movable member 140.
　なお、ルーバー１２０が開状態（図９（ａ）に示す閉状態以外の状態）の全範囲において、遮光板１２１～１２６の各々が、図５に示す前後方向に沿う線上の想定点に、同時に向くようにする必要はなく、ルーバー１２０が開状態の範囲内のうち特定範囲において、同時に向くようにすればよい。この特定範囲は、運転席の前後方向の調整可能範囲に応じて、適切に定めればよい。第１実施形態の説明は以上である。 Note that, in the entire range of the louver 120 in an open state (a state other than the closed state shown in FIG. 9A), each of the light shielding plates 121 to 126 simultaneously reaches an assumed point on a line along the front-rear direction shown in FIG. The louvers 120 do not have to face each other, and the louvers 120 may face each other in a specific range within the open state. This specific range may be appropriately determined according to the adjustable range in the front-rear direction of the driver's seat. This is the end of the description of the first embodiment.
　ここからは、支持体と可動部材との位置関係が第１実施形態とは異なる、第２実施形態に係る死角補助装置２００を説明する。以下では、第１実施形態とは異なる点を中心に説明を行う。なお、第１実施形態と同様の機能を有する部材については、第１実施形態と同一の符号を付して適宜説明を省略する。 From here, the blind spot assisting device 200 according to the second embodiment, in which the positional relationship between the support and the movable member is different from that of the first embodiment, will be described. Below, it demonstrates focusing on a different point from 1st Embodiment. In addition, about the member which has a function similar to 1st Embodiment, the code | symbol same as 1st Embodiment is attached | subjected and description is abbreviate | omitted suitably.
（第２実施形態）
　第２実施形態に係る死角補助装置２００は、第１実施形態と同様の反射部１１０及びルーバー１２０と、図１０及び図１１に示す支持体２３０及び可動部材２４０と、を備える。 (Second Embodiment)
The blind spot assisting device 200 according to the second embodiment includes the same reflector 110 and louver 120 as those in the first embodiment, and the support 230 and the movable member 240 shown in FIGS. 10 and 11.
　第２実施形態に係る死角補助装置２００においては、図１０に示すように、遮光板１２３には、第１実施形態と同様に一対の第１軸部１２７が設けられているが、第２軸部１２８は、上方にのみ突出して設けられている。遮光板１２３以外についても同様に、遮光板１枚につき、一対の第１軸部１２７と、上方にのみ突出した第２軸部１２８とが設けられている。 In the blind spot assisting device 200 according to the second embodiment, as shown in FIG. 10, the light shielding plate 123 is provided with a pair of first shaft portions 127 as in the first embodiment. The portion 128 is provided so as to protrude only upward. Similarly, except for the light shielding plate 123, a pair of first shaft portions 127 and a second shaft portion 128 protruding only upward are provided for each light shielding plate.
　支持体２３０は、図１０に示すように、ルーバー１２０（図１０では遮光板１２３のみ示した）の下側に位置する下板部２３１と、上側に位置する上板部２３２と、を有する。 As shown in FIG. 10, the support body 230 includes a lower plate portion 231 located on the lower side of the louver 120 (only the light shielding plate 123 is shown in FIG. 10) and an upper plate portion 232 located on the upper side.
　下板部２３１には、一対の第１軸部１２７の一方を受ける軸受部２３１ａが形成されている。上板部２３２には、一対の第１軸部１２７の他方を受ける軸受部２３２ａが形成されている。なお、第２実施形態に係る下板部２３１及び上板部２３２には、第１実施形態の規制部１３１ｂ，１３２ｂに相当する穴は設けられていない。つまり、支持体２３０には、一対の軸受部２３１ａ，２３２ａが形成されている。 The lower plate portion 231 is formed with a bearing portion 231 a that receives one of the pair of first shaft portions 127. A bearing portion 232 a that receives the other of the pair of first shaft portions 127 is formed on the upper plate portion 232. Note that the lower plate portion 231 and the upper plate portion 232 according to the second embodiment are not provided with holes corresponding to the restriction portions 131b and 132b of the first embodiment. In other words, the support 230 is formed with a pair of bearing portions 231a and 232a.
　支持体２３０の上板部２３２には、図１０に示すように、下方に突出し、互いに対向する一対の壁部２３２ｂ，２３２ｃが設けられている。この一対の壁部２３２ｂ，２３２ｃの間に形成される凹部は、可動部材２４０をスライド可能に収容する収容部２３３として機能する。つまり、第２実施形態では、可動部材２４０は、支持体２３０（上板部２３２）と遮光板１２３との間に位置する。 As shown in FIG. 10, the upper plate portion 232 of the support body 230 is provided with a pair of wall portions 232 b and 232 c that protrude downward and face each other. The concave portion formed between the pair of wall portions 232b and 232c functions as an accommodating portion 233 that accommodates the movable member 240 in a slidable manner. That is, in the second embodiment, the movable member 240 is located between the support body 230 (upper plate portion 232) and the light shielding plate 123.
　また、上板部２３２は、図１１に示すように、収容部２３３の内面から可動部材２４０に向かって突起する突起部２３３ａが設けられている。突起部２３３ａは、後述のガイド孔２４２内に位置する。 Further, as shown in FIG. 11, the upper plate portion 232 is provided with a protruding portion 233 a that protrudes from the inner surface of the accommodating portion 233 toward the movable member 240. The protrusion 233a is located in a guide hole 242 described later.
　可動部材２４０は、スライド操作によって、支持体２３０の収容部２３３内をスライド方向Ｓに沿ってスライド可能に設けられている。可動部材２４０は、第１実施形態と同様に第２軸部１２８の一部が挿入される挿入部２４１と、図１１に示すガイド孔２４２及び操作ノブ２４３と、を有する。 The movable member 240 is provided so as to be slidable along the sliding direction S in the accommodating portion 233 of the support 230 by a sliding operation. Similar to the first embodiment, the movable member 240 has an insertion portion 241 into which a part of the second shaft portion 128 is inserted, and a guide hole 242 and an operation knob 243 shown in FIG.
　ガイド孔２４２は、スライド方向Ｓに沿って形成され、例えば、隣り合う挿入部２４１の間に位置する。ガイド孔２４２は、可動部材２４０をスライド方向Ｓに沿って安定して移動させるために設けられている。可動部材２４０に対して支持体２３０の突起部２３３ａがガイド孔２４２内をスライド方向Ｓに沿って摺動することにより、可動部材２４０は、スライド方向Ｓに沿って安定して移動することができる。なお、上板部２３２が有する一対の壁部２３２ｂ，２３２ｃの間隔を調整することによって、可動部材２４０をスライド方向Ｓに沿って案内する構成としてもよい。 The guide hole 242 is formed along the sliding direction S, and is located between, for example, the adjacent insertion portions 241. The guide hole 242 is provided for stably moving the movable member 240 along the slide direction S. When the protrusion 233a of the support 230 slides in the guide hole 242 along the slide direction S with respect to the movable member 240, the movable member 240 can move stably along the slide direction S. . In addition, it is good also as a structure which guides the movable member 240 along the slide direction S by adjusting the space | interval of a pair of wall part 232b, 232c which the upper board part 232 has.
　操作ノブ２４３は、可動部材２４０を操作し易くするためのものであり、図１１に示すように、上板部２３２の壁部２３２ｂに形成された切り欠きから、外部に突出するように設けられている。操作ノブ２４３は、可動部材２４０に対して不動であればよく、可動部材２４０と一体であっても別体であってもよい。ユーザは、このように露出した操作ノブ２４３をつまみながら、スライド方向Ｓに動かすことで、可動部材２４０をスライド方向Ｓに動かすことができる。 The operation knob 243 is for facilitating operation of the movable member 240, and is provided so as to protrude outside from a notch formed in the wall portion 232b of the upper plate portion 232 as shown in FIG. ing. The operation knob 243 may be immovable with respect to the movable member 240 and may be integrated with the movable member 240 or may be a separate body. The user can move the movable member 240 in the slide direction S by moving it in the slide direction S while holding the operation knob 243 thus exposed.
　挿入部２４１は、貫通孔として形成され、遮光板１２１～１２６の各々に対応して複数（遮光板と同数）設けられている。なお、１枚の遮光板と１つの挿入部２４１との関係は同様なので、図１１に示した任意の遮光板（遮光板１２３）に着目する。図１１は、下板部２３１を取り外した死角補助装置２００の要部斜視図である。 The insertion portion 241 is formed as a through hole, and a plurality (the same number as the light shielding plates) is provided corresponding to each of the light shielding plates 121 to 126. Since the relationship between one light shielding plate and one insertion portion 241 is the same, attention is paid to an arbitrary light shielding plate (light shielding plate 123) shown in FIG. FIG. 11 is a perspective view of a main part of the blind spot assisting device 200 with the lower plate portion 231 removed.
　挿入部２４１は、図１１に示すように、概ね直線状に形成されている。なお、同図では、挿入部２４１が沿う方向を、方向Ｈとして表している。この方向Ｈとスライド方向Ｓとから分かるように、挿入部２４１は、可動部材２４０の移動方向であるスライド方向Ｓと交差する方向に延びるように形成されている。 The insertion portion 241 is generally formed in a straight line as shown in FIG. In addition, in the same figure, the direction along which the insertion part 241 follows is represented as the direction H. As can be seen from the direction H and the slide direction S, the insertion portion 241 is formed to extend in a direction that intersects the slide direction S, which is the moving direction of the movable member 240.
　挿入部２４１の形状は、可動部材２４０のスライド方向における位置と、当該位置において実現したい遮光板１２３の傾斜角度とから決まる第２軸部１２８の位置を求め、求めた第２軸部１２８の位置の集合からなる軌跡に応じて定められる。
　このように定められる挿入部２４１の形状によって、可動部材２４０の移動量に対する遮光板１２３の傾斜角度（第１軸部１２７を中心とした回転量）が定められている。 The shape of the insertion portion 241 is obtained by obtaining the position of the second shaft portion 128 determined from the position of the movable member 240 in the sliding direction and the inclination angle of the light shielding plate 123 to be realized at the position, and obtaining the position of the obtained second shaft portion 128. It is determined according to the trajectory consisting of a set of
The inclination angle of the light shielding plate 123 with respect to the amount of movement of the movable member 240 (the amount of rotation about the first shaft portion 127) is determined by the shape of the insertion portion 241 thus determined.
　可動部材２４０に遮光板１２１～１２６の各々に対応して形成された挿入部２４１は、遮光板１２１～１２６の各々に設けられた第２軸部１２８の可動範囲を規制する。また、可動部材２４０は、第１実施形態と同様に、遮光板１２１～１２６の各々が視点２に同時に向くように形成される。可動部材２４０の移動量に対しての遮光板１２１～１２６の回転量は、それぞれ異なるため、複数の挿入部２４１は、各々異なる形状で形成される。各挿入部２４１の形状は、想定点の位置と、当該想定点を同時に追うことが可能な遮光板１２１～１２６の角度と、可動部材２４０のスライド量との関数により定めることが可能である。このように定めると、挿入部２４１の各々は、直線的な形状に限られず、傾斜角度も適宜に異なることになる。また、挿入部２４１の形状として、可動部材２４０のスライド量に対する遮光板１２１～１２６それぞれの回転量を調整すべく曲率が徐変する曲線が含まれてもよい。 The insertion portion 241 formed on the movable member 240 corresponding to each of the light shielding plates 121 to 126 regulates the movable range of the second shaft portion 128 provided on each of the light shielding plates 121 to 126. In addition, the movable member 240 is formed so that each of the light shielding plates 121 to 126 faces the viewpoint 2 at the same time as in the first embodiment. Since the amount of rotation of the light shielding plates 121 to 126 with respect to the amount of movement of the movable member 240 is different, the plurality of insertion portions 241 are formed in different shapes. The shape of each insertion portion 241 can be determined by a function of the position of the assumed point, the angles of the light shielding plates 121 to 126 that can simultaneously follow the assumed point, and the sliding amount of the movable member 240. If it defines in this way, each of the insertion part 241 will not be restricted to a linear shape, but an inclination angle will also differ suitably. Further, the shape of the insertion portion 241 may include a curve whose curvature gradually changes so as to adjust the rotation amount of each of the light shielding plates 121 to 126 with respect to the sliding amount of the movable member 240.
　第２実施形態に係る死角補助装置２００における、可動部材２４０の移動による遮光板１２１～１２６の回転動作（角度調整）は、第１実施形態と同様である。なお、第１実施形態に係る挿入部１４１も、図９（ｂ）及び（ｃ）を参照して分かるように、スライド方向Ｓと交差する方向に延びるように形成されている。また、挿入部１４１の形状によって、可動部材１４０の移動量に対する遮光板１２３の傾斜角度が定められている点も同様である。また、第１実施形態では、支持体１３０に形成した規制部１３１ｂ，１３２ｂにより、第２軸部１２８の可動範囲を規制する例を示したが、これに限られない。例えば、第２軸部１２８の可動範囲は、挿入部１４１の形状によって規制され、支持体１３０に形成した規制部１３１ｂ，１３２ｂに相当する構成は、第２軸部１２８の移動を妨げないように、第２軸部１２８と当接しないように形成されるものであってもよい。 Rotational operation (angle adjustment) of the light shielding plates 121 to 126 by the movement of the movable member 240 in the blind spot assisting device 200 according to the second embodiment is the same as that of the first embodiment. In addition, the insertion part 141 which concerns on 1st Embodiment is also formed so that it may extend in the direction which cross | intersects the sliding direction S so that it may understand with reference to FIG.9 (b) and (c). The same is true in that the shape of the insertion portion 141 determines the inclination angle of the light shielding plate 123 relative to the amount of movement of the movable member 140. Moreover, although 1st Embodiment showed the example which controls the movable range of the 2nd axial part 128 by the control parts 131b and 132b formed in the support body 130, it is not restricted to this. For example, the movable range of the second shaft portion 128 is restricted by the shape of the insertion portion 141, and the configuration corresponding to the restriction portions 131b and 132b formed on the support 130 does not hinder the movement of the second shaft portion 128. Further, it may be formed so as not to contact the second shaft portion 128.
　なお、本発明は上記実施形態及び図面によって限定されるものではない。上記実施形態及び図面に変更（構成要素の削除も含む）を加えることができるのはもちろんである。 In addition, this invention is not limited by the said embodiment and drawing. It goes without saying that changes (including deletion of components) can be added to the embodiment and the drawings.
　以上では、操作性を踏まえ、可動部材１４０，２４０を用いて一度に各遮光板１２１～１２６を調整する例を示したが、これに限られない。遮光板１２１～１２６の各々を別々に調整可能としてもよい。また、可動部材１４０，２４０を、支持体１３０の上板部１３２側でなく、下板部１３１側に設けてもよい。また、連動する可動部材１４０，２４０を２つ用意し、一方を上板部１３２側に、他方を下板部１３１側に設けるようにしてもよい。 In the above, an example in which the light shielding plates 121 to 126 are adjusted at once using the movable members 140 and 240 in consideration of operability has been described, but the present invention is not limited thereto. Each of the light shielding plates 121 to 126 may be separately adjustable. Further, the movable members 140 and 240 may be provided not on the upper plate portion 132 side of the support 130 but on the lower plate portion 131 side. Alternatively, two movable members 140 and 240 to be interlocked may be prepared, and one may be provided on the upper plate portion 132 side and the other on the lower plate portion 131 side.
　また、可動部材１４０，２４０のスライド操作が電動で行われる構成としてもよい。ただし、死角補助装置１００，２００は、電動制御のカメラや画像表示器等を必要とすることなく、死角領域Ｄの像を視認可能である点が優れた点の一つであるため、この優れた点を考慮して死角補助装置１００，２００を構成することが好ましい。 Further, the movable members 140 and 240 may be configured to be electrically operated by a slide operation. However, since the blind spot assisting devices 100 and 200 are one of the excellent points that an image of the blind spot area D can be visually recognized without requiring an electrically controlled camera, an image display, or the like. It is preferable to configure the blind spot assisting devices 100 and 200 in consideration of the above points.
　また、ルーバー１２０を構成する遮光板の数は任意である。複数であることが好ましいが、遮光板は１枚であってもよい。また、ルーバー１２０の閉状態（第１ミラー１１１が覆われる状態）を用意しなくともよい。ただし、閉状態を用意したほうが、死角補助装置１００の不使用時に、第１ミラー１１１にゴミや埃が付着することや、傷がつくことなどを防止することができ、好ましい。また、遮光板１２１～１２６の素材は任意である。例えば、シリコーンなどの柔軟性を有する材料によって構成すれば、視認者等が誤って死角補助装置１００に接触した際に緩衝部材としての機能を果たすことができる。 Further, the number of light shielding plates constituting the louver 120 is arbitrary. Although it is preferable to have a plurality of light shielding plates, the number of light shielding plates may be one. Further, it is not necessary to prepare a closed state of the louver 120 (a state in which the first mirror 111 is covered). However, it is preferable to prepare the closed state because dust and dust can be prevented from being attached to the first mirror 111 and scratched when the blind spot assisting device 100 is not used. The material of the light shielding plates 121 to 126 is arbitrary. For example, if it is made of a flexible material such as silicone, it can serve as a buffer member when a viewer or the like accidentally contacts the blind spot assisting device 100.
　以上では、死角補助装置１００，２００が右側のピラー５０に配置される例を示したが、左側のピラー６０に配置してもよい。また、死角補助装置１００，２００を、左右のピラー５０，６０双方に配置してもよい。また、死角補助装置１００，２００は、車両１のセンターピラーやリアピラーなどに配置され、これらによって遮られる死角領域の像を映すものであってもよい。 Although the example in which the blind spot assisting devices 100 and 200 are arranged on the right pillar 50 has been described above, they may be arranged on the left pillar 60. Moreover, you may arrange | position the blind spot auxiliary | assistance apparatus 100,200 in both the left and right pillars 50,60. Further, the blind spot assisting devices 100 and 200 may be arranged on a center pillar, a rear pillar, or the like of the vehicle 1 and project an image of a blind spot area blocked by these.
　また、死角補助装置１００，２００は、車両以外の用途にも広く適用することができる。例えば、住宅に用いる場合、大面積の死角補助装置１００，２００を天井に取り付けて、外光の入射部分のみを屋外に向ける（壁などから屋外に露出するようにしてもよい）ことで、屋内に居ながら空の様子を見ることができたり、屋内に太陽光を導いたりすることができる。これは、住宅密集地や通常の窓を付けられない事情のある住宅には特に好適である。 Also, the blind spot assisting devices 100 and 200 can be widely applied to uses other than vehicles. For example, when used in a house, the blind spot assisting devices 100 and 200 having large areas are attached to the ceiling, and only the incident portion of the outside light is directed outdoors (may be exposed to the outdoors from a wall or the like), so that You can see the sky and stay indoors and guide the sunlight indoors. This is particularly suitable for densely populated houses and houses with circumstances that cannot be fitted with normal windows.
　また、例えば観光施設等の高層建築物で、高層階の床下に大面積の死角補助装置１００，２００を埋め込み、光入射部分のみを屋外に出すことで、床下の死角補助装置１００，２００で眼下の風景を直接足下に感じることが可能となり、建築物の高さを強調することができる。同様の効果を得るために、従来は床下に空間を設ける必要があったが、死角補助装置１００，２００によれば既存の建築物にも容易に配置することができ好適である。 In addition, for example, in a high-rise building such as a tourist facility, a blind spot assisting device 100, 200 having a large area is embedded under the floor of a higher floor, and only the light incident part is exposed to the outside. It is possible to feel the scenery directly under the feet, and to emphasize the height of the building. In order to obtain the same effect, it has been conventionally necessary to provide a space under the floor. However, the blind spot assisting devices 100 and 200 are suitable because they can be easily arranged in existing buildings.
　また、道路に近接して塀が立っている見通しの悪い交差点などにおいて、塀の角に死角補助装置１００，２００を配置することで、死角領域の歩行者や車両の存在をいち早く認識可能なようにしてもよい。こうすれば、出会い頭の事故の防止に貢献することができる。 In addition, by arranging the blind spot assisting devices 100 and 200 at the corners of the saddle at an intersection where the fence is standing near the road and has a poor visibility, it is possible to quickly recognize the presence of pedestrians and vehicles in the blind spot area. It may be. In this way, it can contribute to the prevention of encounter accidents.
