Description

本発明は、薄板状フレネルミラーの取付け構造に関する。   The present invention relates to a mounting structure for a thin plate Fresnel mirror.

フレネルミラーは、特許文献１等で周知のように、フラットな形状であるのに凸面鏡または凹面鏡の機能を有している。このうち、凸面鏡機能を有するフレネルミラーは、建物内の交差路などの壁面に取り付けられて、死角確認用の衝突防止手段として利用されている（例えば特許文献２参照）。壁面にミラーを取り付ける場合、凸面鏡の場合は取付けアームやボルト、ナットなどの取付け手段を使用するが、フレネルミラーでは、形状がフラットであるため、ボルト、ナットなどの取付け具は使用せず、両面接着テープなどの貼付け手段だけで壁面に面状に貼り付けることができる。そのため、壁に穴を開けることができない賃貸建物などの場合であっても、簡単に取り付けを行うことができる。
しかし、両面接着テープだけの取付けでは、フレネルミラーの重量が大きすぎると剥離落下の問題があるので、或る程度軽量であることが必要になる。その軽量化のための効果的な対策としては、フレネルミラーを薄肉化することであるが、好ましくは総厚さを１．０ｍｍ以下にすることである。このようなフレネルミラーの薄板化は、最近の加工技術の向上により容易に行えるようになっている。The Fresnel mirror has a function of a convex mirror or a concave mirror although it is a flat shape as well known in Patent Document 1 and the like. Among these, a Fresnel mirror having a convex mirror function is attached to a wall surface such as an intersection in a building and used as a collision prevention means for checking blind spots (for example, see Patent Document 2). When mounting a mirror on a wall, mounting means such as mounting arms, bolts, and nuts are used for convex mirrors, but Fresnel mirrors are flat in shape and do not use bolts, nuts, or other mounting tools. It can be affixed to the wall surface in a planar manner only by affixing means such as an adhesive tape. Therefore, even in the case of a rental building or the like that cannot make a hole in the wall, it can be easily attached.
However, when only the double-sided adhesive tape is attached, there is a problem of peeling and dropping if the weight of the Fresnel mirror is too large. An effective measure for reducing the weight is to reduce the thickness of the Fresnel mirror, but it is preferable to set the total thickness to 1.0 mm or less. Such thinning of the Fresnel mirror can be easily performed by recent improvements in processing technology.

一方、フレネルミラーの凸面鏡機能の特徴は、凸面鏡の球面の曲率半径に相当する見掛けの曲率半径を小さくするほど視野を拡大できるが、映像が小さくなって判別し難くなり、また見掛けの曲率半径を大きくすると映像が大きく見易くなるが、視野が狭くなってしまうという特性がある。フレネルミラーを死角確認用手段として使用する場合には、映像が大きく見易くなることは望ましいが、視野が狭くなることは致命的な欠点であるので、視野も広くなることが望ましい。   On the other hand, the feature of the convex mirror function of the Fresnel mirror is that the visual field can be enlarged as the apparent radius of curvature corresponding to the radius of curvature of the convex mirror is reduced, but the image becomes smaller and difficult to discern, and the apparent radius of curvature is reduced. Larger images make the image larger and easier to see, but have the property of narrowing the field of view. When the Fresnel mirror is used as the blind spot confirmation means, it is desirable that the image is large and easy to see, but since narrowing the field of view is a fatal defect, it is desirable that the field of view be widened.

そこでフレネルミラーを使用して、上記のような要望を可能にするには、フレネルミラーの壁面への取付けを、従来のような全体的な貼付けによる面状の取付けではなく、部分的な貼付けによる傾斜状態の取付けとすることで、視野の拡大を図るようにすることが考えられる。しかし、上述のようにフレネルミラーの総厚さを１．０ｍｍ以下という極薄にしたものでは、曲げ剛性が低下し可撓性になるため、壁面に面状に貼り付けるのであれば問題ないが、上述のように傾斜状態に取り付ける場合には、フレネルミラーが撓みやすくなって映像に歪みが生じる場合がある。   Therefore, in order to enable the above-mentioned demands using a Fresnel mirror, the mounting of the Fresnel mirror to the wall surface is not by the surface mounting by general pasting as in the past, but by partial pasting. It is conceivable to expand the field of view by mounting in an inclined state. However, if the total thickness of the Fresnel mirror is as thin as 1.0 mm or less as described above, the bending rigidity is reduced and the film becomes flexible. When mounting in an inclined state as described above, the Fresnel mirror is likely to bend and the image may be distorted.

以下、本発明の実施態様を説明するが、本発明は以下に説明する態様に限定されず、特許請求の範囲に記載の精神および範囲から逸脱しない任意の変更態様が包含される。図面において、同一の符号が付された要素は、同様の構成または機能を有することを意味する。   Hereinafter, embodiments of the present invention will be described, but the present invention is not limited to the embodiments described below, and includes any modifications that do not depart from the spirit and scope described in the claims. In the drawings, elements denoted by the same reference numerals have the same configuration or function.

本発明の実施態様を説明する前に、取付け対象のフレネルミラーについて説明する。   Before describing the embodiment of the present invention, a Fresnel mirror to be attached will be described.

本発明において取付け対象のフレネルミラー１は、図８に示すように、主要部がフラットな透明プラスチック板５からなる。透明プラスチック板５の裏面側に、多数の環状の傾斜面６が中心軸Ｏの周りに同心円状かつ多段に形成され、これら傾斜面６にアルミニウム等の金属膜が被覆されて反射面７を形成している。さらに反射面７に保護層８として塗料が塗布され、その保護層８の外側にプラスチックの裏板９が貼り付けられている。ただし、裏板９は必ずしも必要ではなく、省略されていても良い。このように形成されたフレネルミラー１の透明プラスチック板５側が鏡面１ａになり、裏板９側が裏面１ｂになる。   As shown in FIG. 8, the Fresnel mirror 1 to be mounted in the present invention is made of a transparent plastic plate 5 whose main part is flat. A large number of annular inclined surfaces 6 are formed concentrically and in multiple stages around the central axis O on the back surface side of the transparent plastic plate 5, and the reflecting surfaces 7 are formed by coating these inclined surfaces 6 with a metal film such as aluminum. doing. Further, a coating material is applied to the reflecting surface 7 as a protective layer 8, and a plastic back plate 9 is attached to the outside of the protective layer 8. However, the back plate 9 is not necessarily required and may be omitted. The transparent plastic plate 5 side of the Fresnel mirror 1 formed in this way is the mirror surface 1a, and the back plate 9 side is the back surface 1b.

フレネルミラー１に形成された同心状で多段の環状の反射面７は、凸面鏡の鏡面を同心状に輪切りにした多数の環状傾斜面を平面状に並べ替えたものに相当する。したがって、フレネルミラー１は凸面鏡と同等の反射機能を有し、凸面鏡の球面の曲率半径に対応する見掛けの曲率半径を有し、その見掛けの曲率半径が大きいほど、映像が大きく見易くなるが視野が狭くなる。また、見掛けの曲率半径が小さいほど、視野は拡大するが映像が小さく判別し難くなるという凸面鏡と同じ特性を有する。   The concentric and multistage annular reflecting surface 7 formed on the Fresnel mirror 1 corresponds to a large number of annular inclined surfaces in which the mirror surfaces of the convex mirrors are concentrically arranged in a plane. Accordingly, the Fresnel mirror 1 has a reflection function equivalent to that of a convex mirror, and has an apparent radius of curvature corresponding to the radius of curvature of the spherical surface of the convex mirror. The larger the apparent radius of curvature, the larger the image becomes easier to see but the field of view becomes. Narrow. In addition, the smaller the apparent radius of curvature, the larger the field of view, but the smaller the image becomes, and the same characteristics as a convex mirror that makes it difficult to discriminate.

したがって、このフレネルミラー１を交差路の壁面に死角確認手段として取り付ける場合、映像を大きくするため見掛けの曲率半径を大きくすると視野が狭くなり、視認可能な死角領域は狭くなる。映像を大きくしながら必要な死角確認領域を確保するには、フレネルミラーを特許文献２のように壁面に面状に貼り付けずに、図５や図６に例示するように、フレネルミラーの縁部だけ壁面Ｗに取り付け傾斜状態にするのがよい。   Therefore, when this Fresnel mirror 1 is attached to the wall surface of the intersection as a blind spot confirmation means, the visual field is narrowed and the visible blind spot area is narrowed if the apparent radius of curvature is increased in order to enlarge the image. In order to secure the necessary blind spot confirmation region while enlarging the image, the edge of the Fresnel mirror is used as shown in FIGS. It is preferable that only the portion is attached to the wall surface W to be in an inclined state.

しかし、フレネルミラーを壁面に傾斜状態に接着だけで取り付けると、幅方向の縁部だけの接着であるため支持が不安定になる。それを回避するには、フレネルミラーを極力軽量化して、縁部の接着部に対する重量負荷を極力小さくする必要がある。本発明では、その対策として取付け対象のフレネルミラーの総厚さを０．３ｍｍ以上１．０ｍｍ以下の薄板状にする。しかし、このように薄板状にしたフレネルミラーは、当業者が手の力だけで容易に曲げられる可撓性を有するため、単に壁面に傾斜状態に取り付けるだけでは、撓みにより映像に歪みを生ずることがある。   However, if the Fresnel mirror is attached to the wall surface in an inclined state only by bonding, the support becomes unstable because it is bonding only at the edge in the width direction. In order to avoid this, it is necessary to reduce the weight of the Fresnel mirror as much as possible and to reduce the weight load on the bonded portion of the edge as much as possible. In the present invention, as a countermeasure, the total thickness of the Fresnel mirror to be attached is made a thin plate having a thickness of 0.3 mm to 1.0 mm. However, since the Fresnel mirror made into a thin plate in this way has the flexibility that a person skilled in the art can easily bend it with only the force of the hand, simply attaching it to the wall surface in an inclined state can cause distortion in the image due to the bending. There is.

図１及び図２は、本発明の実施態様を示し、図５はＬ字交差路Ｃlにおける壁面Ｗに取り付けた場合を例示し、図６はＴ字交差路Ｃtにおける壁面Ｗに取り付けた場合を例示する。   1 and 2 show an embodiment of the present invention. FIG. 5 illustrates the case of being attached to the wall surface W at the L-shaped intersection C1 and FIG. 6 is the case of being attached to the wall surface W at the T-shaped intersection Ct. Illustrate.

図１及び図２において、フレネルミラー１は総厚さが０．３ｍｍ以上１．０ｍｍ以下の薄板状である。この薄板状フレネルミラー１が、鏡面１ａを外側に、裏面１ｂを壁面Ｗ側に向け、横幅方向の一方の縁部を連結治具２により壁面Ｗに連結され、かつ幅方向の中間部が角度調整治具３により壁面Ｗに対して傾斜角度αをなすように傾斜状態に取り付けられている。   1 and 2, the Fresnel mirror 1 has a thin plate shape with a total thickness of 0.3 mm to 1.0 mm. The thin plate-like Fresnel mirror 1 has the mirror surface 1a facing outward, the back surface 1b facing the wall surface W, one edge in the width direction is connected to the wall surface W by the connecting jig 2, and the intermediate portion in the width direction is angled. The adjusting jig 3 is attached in an inclined state so as to form an inclination angle α with respect to the wall surface W.

上記連結治具２は、ストリップ状支持板２１と取付板２２とを屈曲部２３を介してＶ字状かつ屈曲自在に連結して構成され、そのストリップ状支持板２１をフレネルミラー１の幅方向の縁部に接着させ、取付板２２を壁面Ｗに接着させている。ストリップ状支持板２１及び取付板２２の接着は、それぞれ両面接着テープ４により行われる。   The connecting jig 2 is configured by connecting a strip-shaped support plate 21 and a mounting plate 22 via a bent portion 23 so as to be V-shaped and bendable, and the strip-shaped support plate 21 is connected in the width direction of the Fresnel mirror 1. The attachment plate 22 is adhered to the wall surface W. The strip-shaped support plate 21 and the attachment plate 22 are bonded to each other by the double-sided adhesive tape 4.

上記ストリップ状支持板２１はフレネルミラー１の縁部に対して、その縁部の上下方向長さの少なくとも８０％以上１００％以下の長さに亘るように接着している。このようにストリップ状支持部２１がフレネルミラー１の縁部に長手方向の略全体に接着していることにより、薄板状フレネルミラーの曲げ剛性が向上し、傾斜状態の取付けであっても撓みを発生しにくくなって、映像にも歪みが発生しなくすることができる。   The strip-shaped support plate 21 is bonded to the edge of the Fresnel mirror 1 so as to extend over a length of at least 80% to 100% of the vertical length of the edge. As described above, the strip-like support portion 21 is bonded to the edge of the Fresnel mirror 1 substantially in the longitudinal direction, so that the bending rigidity of the thin plate-like Fresnel mirror is improved. It becomes difficult to occur, and distortion can be prevented from occurring in the video.

また、ストリップ状支持板２１の幅としては、好ましくはフレネルミラー１の幅方向長さの１０％〜２５％であるようにするのがよい。また、ストリップ状支持板２１をフレネルミラー１の縁部に接着させる両面接着テープ４は、図２に示すように、ストリップ状支持板２１の長手方向の両端部２カ所のほか、中間部１カ所を加えた少なくとも３カ所に配置するとよく、さらに好ましくは、ストリップ状支持板２１の長手方向全長に連続配置するとよい。ストリップ状支持板２１および取付板２２の厚さは、好ましくは０．３ｍｍ〜２．０ｍｍにするのがよい。   The width of the strip-shaped support plate 21 is preferably 10% to 25% of the length in the width direction of the Fresnel mirror 1. Further, as shown in FIG. 2, the double-sided adhesive tape 4 for bonding the strip-shaped support plate 21 to the edge portion of the Fresnel mirror 1 has one intermediate portion in addition to the two end portions in the longitudinal direction of the strip-shaped support plate 21. It is good to arrange in at least three places to which is added. More preferably, it is good to arrange continuously in the longitudinal direction full length of the strip-like support plate 21. The thickness of the strip-like support plate 21 and the mounting plate 22 is preferably 0.3 mm to 2.0 mm.

一方、角度調整治具３は、支持部３５を中間に有し、その支持部３５の前後両端に対して、一方に屈曲部３３を介して板状接着部３１を屈曲自在に連結し、他方に屈曲部３４を介して板状接着部３２を屈曲自在に連結して構成されている。一方の板状接着部３１はフレネルミラー１の幅方向中間部に両面接着テープ４で接着させ、他方の板状接着部３２は壁面Ｗに両面接着テープ４で接着させる。この角度調整治具３の取り付けにより、フレネルミラー１の壁面Ｗに対する傾斜角度αが一定に保持される。フレネルミラー１の傾斜角度αは、板状接着部３２の壁面Ｗに沿う方向の接着位置を板状接着部３１に対して相対的に変位させることにより変化させることができる（例えば傾斜角度α’のように）。   On the other hand, the angle adjusting jig 3 has a support portion 35 in the middle, and a plate-like adhesive portion 31 is flexibly connected to the front and rear ends of the support portion 35 via a bent portion 33 on the other side. The plate-like adhesive portion 32 is connected to bendable via a bent portion 34. One plate-like adhesive portion 31 is adhered to the intermediate portion in the width direction of the Fresnel mirror 1 with the double-sided adhesive tape 4, and the other plate-like adhesive portion 32 is adhered to the wall surface W with the double-sided adhesive tape 4. By attaching the angle adjusting jig 3, the inclination angle α with respect to the wall surface W of the Fresnel mirror 1 is kept constant. The inclination angle α of the Fresnel mirror 1 can be changed by displacing the bonding position in the direction along the wall surface W of the plate-like adhesive portion 32 relative to the plate-like adhesive portion 31 (for example, the inclination angle α ′ like).

薄板状フレネルミラー１を壁面Ｗに取り付ける際の作業は、図２のように予めフレネルミラー１の裏面１ｂに連結治具２と角度調整治具３とを取り付けた状態にしてから実施するとよい。例えば、図５のようにフレネルミラー１をＬ字交差路Ｃｌにおける壁面Ｗに取り付けるときは、先ず壁面Ｗに対する取付け高さを設定し、その高さにフレネルミラー１の裏面１ｂにある連結治具２の取付板２２を両面接着テープ４により接着させる。次いで、フレネルミラー１を連結治具２の屈曲部２３を支点に揺動させて、フレネルミラー１の映像を覗きながら、その中に必要な死角領域が含まれるようにフレネルミラーの傾斜角度αを調整した後、角度調整治具３の板状接着部３２を壁面Ｗに接着させ、上記調整した傾斜角度αを確定させる。   The operation when attaching the thin plate-like Fresnel mirror 1 to the wall surface W is preferably performed after the connecting jig 2 and the angle adjusting jig 3 are attached to the back surface 1b of the Fresnel mirror 1 in advance as shown in FIG. For example, when the Fresnel mirror 1 is attached to the wall surface W in the L-shaped intersection Cl as shown in FIG. 5, the attachment height with respect to the wall surface W is first set, and the connecting jig on the back surface 1b of the Fresnel mirror 1 is set to that height. The two mounting plates 22 are bonded by the double-sided adhesive tape 4. Next, the Fresnel mirror 1 is swung with the bent portion 23 of the connecting jig 2 as a fulcrum, and while looking at the image of the Fresnel mirror 1, the inclination angle α of the Fresnel mirror is set so that the necessary blind spot area is included therein. After the adjustment, the plate-like adhesive portion 32 of the angle adjustment jig 3 is adhered to the wall surface W to determine the adjusted inclination angle α.

上述した連結治具２および角度調整治具３は、それぞれ帯状のプラスチック板から一体に製作することができる。連結治具２の場合は、図９に示すように、帯状のプラスチック板の幅方向の中央に凹状溝２５を長手方向に沿って直線状に成形し、その凹状溝２５を屈曲部２３として、左右両側にストリップ状支持部２１と取付部２２とを形成する。角度調整治具３の場合は、帯状プラスチック板の長手方向の中間に、前後２箇所の凹溝状の屈曲部３３，３４によって区分された支持部３５を形成すればよい。これにより、支持部３５の前後方向の一方に屈曲部３３を介して板状接着部３１が形成され、他方に屈曲部３４を介して板状接着部３２が形成される。   The connecting jig 2 and the angle adjusting jig 3 described above can be integrally manufactured from a strip-shaped plastic plate. In the case of the connecting jig 2, as shown in FIG. 9, a concave groove 25 is formed linearly along the longitudinal direction in the center in the width direction of the belt-shaped plastic plate, and the concave groove 25 is used as a bent portion 23. A strip-like support portion 21 and an attachment portion 22 are formed on both the left and right sides. In the case of the angle adjusting jig 3, a support portion 35 divided by two concave and convex bent portions 33 and 34 at the front and rear portions may be formed in the middle of the longitudinal direction of the belt-shaped plastic plate. As a result, the plate-like adhesive portion 31 is formed on one side of the support portion 35 in the front-rear direction via the bent portion 33, and the plate-like adhesive portion 32 is formed on the other side via the bent portion 34.

連結治具２及び角度調整治具３の製作に使用する帯状のプラスチック材としては、例えばポリエチレン、ポリプロピレン、ＡＢＳ、ポリ塩化ビニル、ポリエチレンテレフタレートなどを例示することが出来る。帯状のプラスチック板の厚さは、０．３ｍｍ〜２．０ｍｍが好ましい。   Examples of the strip-shaped plastic material used for manufacturing the connecting jig 2 and the angle adjusting jig 3 include polyethylene, polypropylene, ABS, polyvinyl chloride, and polyethylene terephthalate. The thickness of the strip-shaped plastic plate is preferably 0.3 mm to 2.0 mm.

本発明において、薄板状フレネルミラーの形状は特に限定されないが、好ましくは四角形にするのがよい。四角形としては、長方形及び正方形のいずれであってもよい。四角形の一辺当たりの長さは、１００ｍｍ以上４００ｍｍ以下が好ましい。フレネルミラーの映像を大きく見やすくする場合の凸面鏡機能の見掛けの曲率半径としては、２００ｍｍ〜９００ｍｍが好ましく、さらに好ましくは２５０ｍｍ〜９００ｍｍがよい。   In the present invention, the shape of the thin plate-shaped Fresnel mirror is not particularly limited, but is preferably a quadrangular shape. The rectangle may be either a rectangle or a square. The length per side of the rectangle is preferably 100 mm or more and 400 mm or less. The apparent radius of curvature of the convex mirror function for making the Fresnel mirror image large and easy to see is preferably 200 mm to 900 mm, more preferably 250 mm to 900 mm.

図３及び図４は、本発明の他の実施態様を示し、図７は、これをＬ字交差路Ｃlにおける壁面Ｗに取り付けた場合を例示する。
図３及び図４において、薄板状のフレネルミラー１は、交差路で直角に接続する二つの壁面Ｗ，Ｗ間に跨るように架け渡され、かつ幅方向の両縁部を連結治具２，２により両壁面Ｗ，Ｗに接着させて傾斜状態に取り付けられている。3 and 4 show another embodiment of the present invention, and FIG. 7 illustrates a case where this is attached to the wall surface W in the L-shaped intersection Cl.
3 and 4, the thin plate-like Fresnel mirror 1 is laid across two wall surfaces W, W connected at right angles at the intersection, and both edges in the width direction are connected to the connecting jig 2, 2 is attached to both wall surfaces W, W in an inclined state.

薄板状フレネルミラー１の幅方向両端部に取り付けられた連結治具２，２は、前述した実施態様に使用されている連結治具２と同じ構成であり、そのストリップ状支持板２１を両面接着テープ４によりフレネルミラー１の幅方向の縁部に接着させ、取付板２２を両面接着テープ４により壁面Ｗに接着させている。しかも、フレネルミラー１の幅方向の縁部に接着させたストリップ状支持板２１は、その縁部の上下方向長さの少なくとも８０％以上１００％以下の長さに亘って接着している。   The connecting jigs 2 and 2 attached to both ends in the width direction of the thin plate-like Fresnel mirror 1 have the same configuration as the connecting jig 2 used in the above-described embodiment, and the strip-like support plate 21 is bonded on both sides. The tape 4 is adhered to the edge in the width direction of the Fresnel mirror 1, and the mounting plate 22 is adhered to the wall surface W by the double-sided adhesive tape 4. Moreover, the strip-like support plate 21 bonded to the edge in the width direction of the Fresnel mirror 1 is bonded over a length of at least 80% to 100% of the vertical length of the edge.

このようにストリップ状支持部２１をフレネルミラー１の幅方向の縁部に接着させたことにより、薄板状フレネルミラー１の曲げ剛性が向上して撓みを発生しにくくなり、そのためフレネルミラー１の映像にも歪みが発生しなくなる。   By adhering the strip-like support portion 21 to the edge in the width direction of the Fresnel mirror 1 in this way, the bending stiffness of the thin plate-like Fresnel mirror 1 is improved and it is difficult for bending to occur. No distortion occurs.

この実施態様において、図７のように、交差路Ｃlに直角に交差する二つの壁面Ｗ，Ｗに薄板状フレネルミラー１を取り付ける際の作業は、前述した実施態様の場合と同様に、図４のように予めフレネルミラー１の裏面１bの両縁部に連結治具２、２を取り付けた状態にしてから実施するとよい。   In this embodiment, as shown in FIG. 7, the operation for attaching the thin plate Fresnel mirror 1 to the two wall surfaces W, W perpendicular to the intersection Cl is the same as that in the above-described embodiment. As described above, the connection jigs 2 and 2 are preferably attached to both edges of the back surface 1b of the Fresnel mirror 1 in advance.

先ず、交差する壁面Ｗ，Ｗに対する取付け高さを設定し、その高さでフレネルミラー１の映像を覗きながら、そのフレネルミラー１の壁面Ｗに対する傾斜角度を変化させる。そして、フレネルミラー１の映像の中に、必要とする死角確認領域が含まれるように傾斜角度を調整し、その最適の傾斜角度αのところで幅方向両縁部の連結治具２，２の取付板２２，２２をそれぞれ壁面Ｗ，Ｗに接着させ、上記調整した傾斜角度αを確定する。   First, the mounting height with respect to the intersecting wall surfaces W, W is set, and the inclination angle of the Fresnel mirror 1 with respect to the wall surface W is changed while looking at the image of the Fresnel mirror 1 at that height. Then, the inclination angle is adjusted so that the necessary blind spot confirmation region is included in the image of the Fresnel mirror 1, and the connecting jigs 2 and 2 at the both edges in the width direction are attached at the optimum inclination angle α. The plates 22 and 22 are bonded to the wall surfaces W and W, respectively, to determine the adjusted inclination angle α.

本発明の薄板状フレネルミラーの取付け構造は、工場、事務所、学校、病院、役所などの屋内の交差路において、衝突防止用の死角確認手段として有効に利用することができる。   The attachment structure of the thin plate-like Fresnel mirror of the present invention can be effectively used as a blind spot confirmation means for collision prevention in indoor intersections such as factories, offices, schools, hospitals, and government offices.
