国際公開第２０１６／１８９７７３号公報International Publication No. 2016/189773

人工光照明装置は高価であるとともに、植物の自由な成長に合わせて光源を最適位置へ移動調整することが必ずしも容易ではない。
また、反射シートを地面に広げる場合も、果樹の上部などには十分な光量の反射光が届きにくくなるなど、必要とする場所へ適正光量の反射光を確保することが困難な場合がある。
そこで本願は、植物の最適場所へ適正光量の反射光を照射でき、かつ安価な反射材及びその製法を提供する。 Artificial light illuminators are expensive, and it is not always easy to move and adjust the light source to the optimum position according to the free growth of the plant.
Further, even when the reflective sheet is spread on the ground, it may be difficult to secure an appropriate amount of reflected light to a required place, for example, it becomes difficult for the reflected light of a sufficient amount of light to reach the upper part of the fruit tree.
Therefore, the present application provides an inexpensive reflective material capable of irradiating the optimum place of the plant with reflected light of an appropriate amount of light and a method for producing the same.

以下、図面に基づいて一実施形態を説明する。
図１は、果実植物１０に対して反射材２０を取付けた状態を示す。なお、反射材２０は直径方向の断面で示してある。
この果実植物１０は、リンゴや桃などの適宜果実１２を有する果樹や、トマトやパプリカ等の適宜果実１２を有する果菜類からなる。果菜類は、地面から高く離れた果実も照射できるようにするため、比較的高性になるものが好ましい。 Hereinafter, one embodiment will be described with reference to the drawings.
FIG. 1 shows a state in which the reflector 20 is attached to the fruit plant 10. The reflective material 20 is shown in a cross section in the radial direction.
The fruit plant 10 is composed of a fruit tree having an appropriate fruit 12 such as an apple or a peach, or a fruit vegetable having an appropriate fruit 12 such as a tomato or paprika. Fruit vegetables are preferably relatively high in quality so that fruits that are far from the ground can be irradiated.

この果実植物１０は茎（幹）１４を、その周囲へ張り出す多数の枝１６を備え、枝１６には果実１２が垂れ下がり状もしくは起立状等種々に形成されている。また、この図では省略されているが、多数の葉も形成されている。 The fruit plant 10 includes a large number of branches 16 having a stem (stem) 14 protruding around the stem (stem) 14, and the fruit 12 is formed in various forms such as a hanging shape or an upright shape on the branch 16. Also, although omitted in this figure, many leaves are also formed.

茎（幹）１４や枝１６には反射材２０が直接取付けられている。茎（幹）１４や枝１６は本願発明における反射材の取付対象部である。
反射材２０は、ほぼ上方へ向かって拡開する傾斜面を有する略円錐状をなす部材であり、反射材２０へ向かって最適光量の反射光を照射する位置に設けられている。
なお、反射光は、反射材２０の内面２２により集光方向に形成される反射光Ｒ１と、外面２４により拡散方向に形成される反射光Ｒ２を含む。 The reflector 20 is directly attached to the stem (trunk) 14 and the branch 16. The stem (trunk) 14 and the branch 16 are attachment target portions of the reflective material in the present invention.
The reflective material 20 is a member having a substantially conical shape having an inclined surface that expands substantially upward, and is provided at a position where an optimum amount of reflected light is emitted toward the reflective material 20.
The reflected light includes the reflected light R1 formed in the condensing direction by the inner surface 22 of the reflector 20 and the reflected light R2 formed in the diffusing direction by the outer surface 24.

反射材２０の設置位置は、反射光Ｒ１が果実１２を照射するのに最適な位置とする。
なお、反射材２０は茎（幹）１４及び枝１６に対して着脱自在である。また茎（幹）１４及び枝１６の長さ方向に沿って移動することも自在であり、植物の成長に合わせて取付位置も適宜移動もしくは変更して調整できる。
さらに、反射材２０の茎（幹）１４及び枝１６に対する取付角度も自由に調整でき、茎（幹）１４及び枝１６に対して適当に傾けて取付けることにより、反射光の方向を最適となるように調整できる。 The position where the reflector 20 is installed is the optimum position for the reflected light R1 to irradiate the fruit 12.
The reflective material 20 is removable from the stem (trunk) 14 and the branch 16. Further, the stem (trunk) 14 and the branch 16 can be freely moved along the length direction, and the mounting position can be appropriately moved or changed according to the growth of the plant.
Further, the mounting angle of the reflector 20 with respect to the stem (stem) 14 and the branch 16 can be freely adjusted, and the direction of the reflected light can be optimized by mounting the reflector 20 at an appropriate inclination with respect to the stem (stem) 14 and the branch 16. Can be adjusted as

図２は反射光の説明図、図３は反射材２０単品の斜視図である。
図２に示すように、反射材２０は、中心線ＣＬに直交する水平面ｈに対してθなる傾きを有する反射面２１（傾斜面）を有する。この反射面２１により、図３にも示すように、反射材２０は、図の上方へ向かって開放された略円錐状の容器状をした立体形状をなす。なお、反射材２０は中心線ＣＬに沿って見たとき円板状をなす。
反射面２１の上方は凹部をなし、この凹部に臨む反射面２１の表面を内面２２とする。また、凹部の反対側は、図の下方へ凸状をなし、この凸側の表面を外面とする。 FIG. 2 is an explanatory view of the reflected light, and FIG. 3 is a perspective view of the reflective material 20 alone.
As shown in FIG. 2, the reflector 20 has a reflecting surface 21 (inclined surface) having an inclination of θ with respect to the horizontal plane h orthogonal to the center line CL. As shown in FIG. 3, the reflective surface 21 makes the reflective material 20 have a three-dimensional shape in the shape of a substantially conical container that is open toward the upper part of the figure. The reflective material 20 has a disk shape when viewed along the center line CL.
The upper part of the reflective surface 21 has a concave portion, and the surface of the reflective surface 21 facing the concave portion is an inner surface 22. Further, the opposite side of the concave portion has a convex shape downward in the drawing, and the surface on the convex side is the outer surface.

内面２２は、反射材２０からの反射光よりなる自然光や人工光もしくは他の種々な方向の入射光Ｌを中心線ＣＬ方向へ集めるように反射する反射光Ｒ１とする集光面をなす。
外面２４は、逆に、入射光を中心線ＣＬから離れる方向へ反射して拡散させる反射光Ｒ２とする拡散面をなす。
外面２４による拡散光は、植物の果実１２や葉などへ光を集中させずに分散して照射することにより広範囲に照射して、果実１２等の生育を促すことにより、光を有効利用する。 The inner surface 22 forms a condensing surface as a reflected light R1 that is reflected so as to collect natural light, artificial light, or other incident light L in various directions, which is composed of the reflected light from the reflective material 20, in the center line CL direction.
On the contrary, the outer surface 24 forms a diffusion surface as the reflected light R2 that reflects and diffuses the incident light in the direction away from the center line CL.
The diffused light from the outer surface 24 is irradiated over a wide range by irradiating the fruits 12 and leaves of the plant in a dispersed manner without concentrating the light, thereby promoting the growth of the fruits 12 and the like, thereby effectively utilizing the light.

反射材２０の中心部には、中心穴２６が貫通して形成され、ここに茎（幹）１４や枝１６を通すようになっている。中心穴２６の直径は、取付対象として最小の細枝の直径よりもさらに小さい程度の小さなものである。 A central hole 26 is formed through the central portion of the reflector 20, through which the stem (trunk) 14 and the branch 16 pass. The diameter of the center hole 26 is as small as the diameter of the smallest twig to be attached.

中心穴２６の周囲には、放射方向へ複数の中心穴スリット２３が形成されている。中心穴スリット２３の一端は中心穴２６に達して開放され、他端は止め穴２５に達している。
止め穴２５は、中心穴スリット２３から反射面２１へ向かって破れが進まないようにするためのものであり、中心穴２６を囲む共通の同心円（仮想）上に形成されている。 A plurality of center hole slits 23 are formed around the center hole 26 in the radial direction. One end of the center hole slit 23 reaches the center hole 26 and is opened, and the other end reaches the stop hole 25.
The stop hole 25 is for preventing the tear from proceeding from the central hole slit 23 toward the reflecting surface 21, and is formed on a common concentric circle (virtual) surrounding the central hole 26.

反射面２１のうち、隣り合う中心穴スリット２３の間において、中心穴２６に臨む部分が自由変形できる自由端２７をなす。
この自由端２７を設けることにより、中心穴２６より大きな直径の茎（幹）１４や枝１６を中心穴２６に通しても、自由端２７が変形してこれを通すとともに、自由端２７が茎（幹）１４や枝１６の外周に密着して長さ方向への移動を阻止する。
このため、反射材２０は中心穴２６により、茎（幹）１４及び枝１６の外周へ直接固定される。 Of the reflecting surfaces 21, the portion facing the center hole 26 forms a free end 27 that can be freely deformed between the adjacent center hole slits 23.
By providing the free end 27, even if a stem (trunk) 14 or a branch 16 having a diameter larger than that of the central hole 26 is passed through the central hole 26, the free end 27 is deformed and passed through, and the free end 27 is passed through the stem. It adheres to the outer periphery of the (trunk) 14 and the branch 16 to prevent movement in the length direction.
Therefore, the reflector 20 is directly fixed to the outer periphery of the stem (trunk) 14 and the branch 16 by the center hole 26.

また、自由端２７が変形自由なため、反射材２０を茎（幹）１４及び枝１６へ直接取付けても、茎（幹）１４及び枝１６が傷付かないように保護される。
しかも、反射材２０を長さ方向へ力を加えることにより、自由端２７を変形させて反射材２０を移動させることができる。このため、反射材２０を取り外すことなく、植物の成長に合わせて反射材２０の取付位置を長さ方向へ移動及び変更調整可能になる。
なお、中心穴スリット２３の数や長さは適宜に設定できる。
また、図３及び図４において、中心穴スリット２３、止め穴２５及び自由端２７の符号指示は、煩雑さを避けるため、一部だけとし、他は省略している。符号Oは反射材２０及び中心穴２６の中心である。 Further, since the free end 27 is freely deformable, even if the reflective material 20 is directly attached to the stem (trunk) 14 and the branch 16, the stem (trunk) 14 and the branch 16 are protected from being damaged.
Moreover, by applying a force to the reflector 20 in the length direction, the free end 27 can be deformed and the reflector 20 can be moved. Therefore, the mounting position of the reflector 20 can be moved and changed in the length direction according to the growth of the plant without removing the reflector 20.
The number and length of the center hole slits 23 can be appropriately set.
Further, in FIGS. 3 and 4, the reference numerals of the center hole slit 23, the stop hole 25, and the free end 27 are only partially shown and the others are omitted in order to avoid complication. Reference numeral O is the center of the reflector 20 and the center hole 26.

次に、反射材２０の成形方法を説明する。
図４は、反射材２０の基になる円板状の原板３０を成形する状態を示す。原板３０は略円板状をなし、反射性部材３１からカットされる。
反射性部材３１は、反射しやすい素材、例えば白色の平板状をなすシート状部材であり、復元弾性に富む、腰がありかつ軽い軟質フォーム材料からなり、例えば発泡スチロールからなる。ただし、ポリエチレンフォーム、ポリウレタンフォーム等適宜フォーム材料が可能である。また、雨に濡れても重くならないようにするため、独立気泡性のものが好ましい。 Next, a method of molding the reflective material 20 will be described.
FIG. 4 shows a state in which the disc-shaped original plate 30 that is the base of the reflective material 20 is formed. The original plate 30 has a substantially disk shape and is cut from the reflective member 31.
The reflective member 31 is a material that is easily reflected, for example, a sheet-like member having a white flat plate shape, is made of a soft foam material having abundant restoring elasticity, and is chewy and light, and is made of, for example, styrofoam. However, foam materials such as polyethylene foam and polyurethane foam can be used as appropriate. Further, in order to prevent the weight from becoming heavy even when it gets wet with rain, a closed cell type is preferable.

なお、腰があるとは、所定大きさの外力（風など）に対して形状保持が可能な剛性を備え、かつ所定大きさを越えた外力により変形しても、この大きな外力が除かれると変形前の状態へ復元する弾力を有する状態を意味する。また、後述する係合部において係合時に曲げても、折れ線を形成して復元できない状態に折れ曲がるようなことがなく、曲げの力を除くと曲げる前の状態に復元できるような性質も含む。 It should be noted that having a waist means that it has rigidity capable of maintaining its shape against an external force of a predetermined size (wind, etc.), and even if it is deformed by an external force exceeding the predetermined size, this large external force is removed. It means a state having elasticity to restore to the state before deformation. Further, even if the engaging portion described later is bent at the time of engagement, it does not bend to a state where it cannot be restored by forming a polygonal line, and it also includes a property that it can be restored to the state before bending when the bending force is removed.

この反射性部材３１に対して、原板３０の外径より若干大きな所定形状に形成されたパンチ型（図示省略）によりプレスカットすれば、原板３０が形成される。３２はこのときの抜き溝である。
なお、このプレスカット時において、中心穴２６、中心穴スリット２３、止め穴２５及びスリット２８並びに係合凸部３４及び係合凹部３５が同時に形成される。係合凸部３４及び係合凹部３５は本願発明における係合部を構成する。 The original plate 30 is formed by press-cutting the reflective member 31 with a punch mold (not shown) formed in a predetermined shape slightly larger than the outer diameter of the original plate 30. Reference numeral 32 denotes a punching groove at this time.
At the time of this press cut, the center hole 26, the center hole slit 23, the stop hole 25 and the slit 28, and the engaging convex portion 34 and the engaging concave portion 35 are formed at the same time. The engaging convex portion 34 and the engaging concave portion 35 form the engaging portion in the present invention.

スリット２８は、原板３０の径方向に、中心穴２６から原板３０の外周部まで連続して形成あれるスリット状の分離部であり、スリット２８に臨む一対の端縁３３を周方向へ分離し、原板３０の外方から茎（幹）１４及び枝１６をスリット２８を通して中心穴２６へ密に入れるようになっている。
このスリット２８を設けることにより、原板３０を、茎（幹）１４や枝１６の側方よりその外周へ取付けることができる。スリット２８の幅Ｗ７（図５）の大きさは自由である。但し、できるだけ狭い方が組立時の反射面積を大きくできる。 The slit 28 is a slit-shaped separating portion formed continuously from the center hole 26 to the outer peripheral portion of the original plate 30 in the radial direction of the original plate 30, and separates the pair of end edges 33 facing the slit 28 in the circumferential direction. , The stem (trunk) 14 and the branch 16 are densely inserted into the center hole 26 through the slit 28 from the outside of the original plate 30.
By providing the slit 28, the original plate 30 can be attached to the outer periphery of the stem (trunk) 14 or the branch 16 from the side. The size of the width W7 (FIG. 5) of the slit 28 is free. However, the one that is as narrow as possible can increase the reflection area at the time of assembly.

係合凸部３４及び係合凹部３５は、中心穴２６の同心円Ｅ１及びＥ２上に形成される。係合凸部３４は一方の端縁３３近くに一つ形成される。
係合凹部３５は他方の端縁３３近くから、同心円Ｅ１及びＥ２上に周方向へ所定間隔もしくは不等間隔で複数形成される。但し、単一でもよい。 The engaging convex portion 34 and the engaging concave portion 35 are formed on the concentric circles E1 and E2 of the center hole 26. One engaging protrusion 34 is formed near one end edge 33.
A plurality of engaging recesses 35 are formed on concentric circles E1 and E2 from the vicinity of the other end edge 33 at predetermined intervals or unequal intervals in the circumferential direction. However, it may be single.

図５は図４の丸囲み部における係合凸部３４及び係合凹部３５を拡大して示す図である。なお、図５中の丸囲み部Aに、係合凸部３４の曲げ時状態、同Ｂに係合凹部３５の曲げ時状態を併せて示してある。
係合凸部３４は、径方向にて比較的幅の狭い基部３６と、その端縁３３側に径方向内外へ張り出した係合拡大部３７を有するよう、抜き溝３８により切り出される。但し、基部３６の係合拡大部３７と反対側部分は、反射面２１と連続して切り離されておらず、接続部３９をなす。 FIG. 5 is an enlarged view showing the engaging convex portion 34 and the engaging concave portion 35 in the circled portion of FIG. The circled portion A in FIG. 5 shows the bent state of the engaging convex portion 34, and the same B shows the bent state of the engaging concave portion 35.
The engaging convex portion 34 is cut out by a drawing groove 38 so as to have a base portion 36 having a relatively narrow width in the radial direction and an engaging expanding portion 37 protruding inward and outward in the radial direction on the end edge 33 side thereof. However, the portion of the base 36 opposite to the engaging expansion portion 37 is not continuously separated from the reflecting surface 21 and forms a connecting portion 39.

係合拡大部３７は、丸囲み部Aに示すように、上から指で押すことにより下方へ押し出され、係合拡大部３７は接続部３９から曲がるようになっている。但し、指を放すと、復元弾性により係合拡大部３７及び基部３６は曲がりからほぼ水平状態に戻る。また、係合拡大部３７を下方へ切り起こし状に曲げると、抜き溝３８に沿って、係合拡大部３７が下方へ突出した後の穴３８ａが形成される。この穴３８ａも、係合拡大部３７が復元変形するとほぼ消滅する。 As shown in the circled portion A, the engagement expanding portion 37 is pushed downward by pushing with a finger from above, and the engaging expanding portion 37 bends from the connecting portion 39. However, when the finger is released, the engagement expanding portion 37 and the base portion 36 return to a substantially horizontal state from bending due to the restoring elasticity. Further, when the engaging expanding portion 37 is bent downward in a raised shape, a hole 38a is formed after the engaging expanding portion 37 protrudes downward along the drawing groove 38. This hole 38a also almost disappears when the engaging expansion portion 37 is restored and deformed.

係合凹部３５は、径方向へ延びる抜き溝４０と、その中間部から周方向へ延びる抜き溝４２を略Ｔ字状に形成し、各抜き溝４０及び抜き溝４２の端部を係合凹部３５にて止めたものである。
抜き溝４０と抜き溝４２の接続部４４は連続している。したがって、係合凹部３５は、抜き溝４２を挟んで径方向外側及び内側の部分が自由変形部４６をなしている。 In the engaging recess 35, a punching groove 40 extending in the radial direction and a punching groove 42 extending in the circumferential direction from the intermediate portion thereof are formed in a substantially T shape, and the end portions of each punching groove 40 and the pulling groove 42 are engaged recesses. It was stopped at 35.
The connection portion 44 between the punch groove 40 and the punch groove 42 is continuous. Therefore, in the engaging recess 35, the outer and inner portions in the radial direction form the free deformation portion 46 with the punching groove 42 interposed therebetween.

丸囲み部Ｂに示すように、抜き溝４２の上から係合拡大部３７を下方へ押し込むと、各自由変形部４６は抜き溝４２を押し開き、接続部４４から下方へ曲がるようになっている。この自由変形部４６の曲がりにより、抜き溝４２部分は大きな開口４８をなし、この開口４８を通って係合拡大部３７を下方へ押し出すことが可能になる。
なお、抜き溝４０の長さ（径方向幅Ｗ５）は、基部３６の径方向幅Ｗ１と略等しい。抜き溝４２の周方向長さは、係合拡大部３７の周方向長さよりも長くなっている。 As shown in the circled portion B, when the engaging expansion portion 37 is pushed downward from above the punching groove 42, each free deformation portion 46 pushes open the pulling groove 42 and bends downward from the connecting portion 44. There is. Due to the bending of the free deformation portion 46, the punching groove 42 portion forms a large opening 48, and the engaging expansion portion 37 can be pushed downward through the opening 48.
The length of the draft groove 40 (diameter width W5) is substantially equal to the radial width W1 of the base portion 36. The circumferential length of the punching groove 42 is longer than the circumferential length of the engaging expansion portion 37.

図６は係合凸部３４の大きさを説明するための図であり、係合凸部３４を係合凹部３５の上へ重ねた状態を示す。基部３６及び係合拡大部３７の上には、指Ｆもしくはこの指Ｆを収容した手袋の指部Ｇが係合凸部３４を押すために置かれる。基部３６の径方向幅Ｗ１及びこれより大きい係合拡大部３７の径方向幅Ｗ２は、それぞれ指Ｆの先端部の幅Ｗ３もしくは手袋の指部Ｇにおける先端部の幅Ｗ４と同程度以上になっている。このため、係合凸部３４を指Ｆの先端部もしくは手袋の指部Ｇで押すことができる。 FIG. 6 is a diagram for explaining the size of the engaging convex portion 34, and shows a state in which the engaging convex portion 34 is overlapped on the engaging concave portion 35. A finger F or a finger portion G of a glove accommodating the finger F is placed on the base portion 36 and the engagement expanding portion 37 to push the engaging convex portion 34. The radial width W1 of the base portion 36 and the radial width W2 of the engagement expanding portion 37 larger than this are equal to or more than the width W3 of the tip portion of the finger F or the width W4 of the tip portion of the finger portion G of the glove, respectively. ing. Therefore, the engaging convex portion 34 can be pushed by the tip portion of the finger F or the finger portion G of the glove.

このようにすると、指Ｆの先端部もしくは手袋の指部Ｇで係合凸部３４を押すだけで容易に係合凸部３４を係合凹部３５と係合させることができる。
しかも、係合凸部３４と係合凹部３５は、上下に重ねて下方へ押し込むだけで係合できるので、係合作業が迅速である。
そのうえ、係合凸部３４と係合凹部３５は原板３０のカット時と同時にワンパンチで形成されるので製造が容易になる。 In this way, the engaging convex portion 34 can be easily engaged with the engaging concave portion 35 simply by pushing the engaging convex portion 34 with the tip portion of the finger F or the finger portion G of the glove.
Moreover, since the engaging convex portion 34 and the engaging concave portion 35 can be engaged by simply stacking them vertically and pushing them downward, the engaging work is quick.
Moreover, since the engaging convex portion 34 and the engaging concave portion 35 are formed by one punch at the same time as the original plate 30 is cut, the manufacturing becomes easy.

特に、手袋の指部Ｇにより係合作業をできるようにしたので、作業中に手袋を着脱せずに済むため、大幅に作業性が向上する、
また、反射材２０の素材を腰のあるものにしたので、係合後に指Ｆもしくは手袋の指部Ｇを放すと、係合凸部３４及び係合凹部３５の変形が復元し、係合状態を堅固に維持できる。また、係合凸部３４の折りしわが付いたままにならないので、強い係合が可能であり、係合凸部３４の曲がったままになることにより、開口部が形成されたままとなることがないので、反射面積の減少を防ぐことができる。 In particular, since the engagement work can be performed by the finger part G of the glove, it is not necessary to put on and take off the glove during the work, so that the workability is greatly improved.
Further, since the material of the reflective material 20 is made to have a waist, when the finger F or the finger portion G of the glove is released after engagement, the deformation of the engaging convex portion 34 and the engaging concave portion 35 is restored, and the engaged state is restored. Can be maintained firmly. Further, since the engaging convex portion 34 does not remain wrinkled, strong engagement is possible, and the engaging convex portion 34 remains bent so that the opening remains formed. Since there is no such thing, it is possible to prevent a decrease in the reflection area.

図７は係合工程を示す。
図７のＡは、図５の７−７線断面である。この図において、係合凸部３４側の端縁３３を係合凹部３５側の端縁３３の上に重ねると、原板３０は、略円錐形の立体形状をなす反射材２０になる。
さらに、係合凸部３４を係合凹部３５の上に重ねると、図７のＢのようになるので、係合凸部３４を指Ｆ（もしくは手袋の指部Ｇ）で下方に押す。
すると、図７のＣに示すように、係合凸部３４は、係合拡大部３７が係合凹部３５の抜き溝４２を押し開いて自由変形部４６を曲げることにより、係合凹部３５の下方へ突出する。
係合拡大部３７の径方向幅Ｗ２は、抜き溝４０の径方向幅Ｗ５よりも大きいため、係合拡大部３７の径方向両端部が抜き溝４０の両端部へ係合し、両端縁３３が連結され、反射材２０となる。 FIG. 7 shows the engagement process.
FIG. 7A is a cross section taken along line 7-7 of FIG. In this figure, when the edge 33 on the engaging convex portion 34 side is overlapped on the edge 33 on the engaging concave portion 35 side, the original plate 30 becomes a reflective material 20 having a substantially conical three-dimensional shape.
Further, when the engaging convex portion 34 is placed on the engaging concave portion 35, the result is as shown in FIG. 7B. Therefore, the engaging convex portion 34 is pushed downward by the finger F (or the finger portion G of the glove).
Then, as shown in C of FIG. 7, in the engaging convex portion 34, the engaging expanding portion 37 pushes open the extraction groove 42 of the engaging concave portion 35 and bends the free deformation portion 46, so that the engaging concave portion 35 is formed. It protrudes downward.
Since the radial width W2 of the engagement expanding portion 37 is larger than the radial width W5 of the punching groove 40, both ends of the engaging expanding portion 37 in the radial direction engage with both ends of the punching groove 40, and both end edges 33. Are connected to form the reflective material 20.

次に、反射材２０の使用方法を説明する。
まず、図４に示すように、反射性部材３１から原板３０をカットする。
この原板３０のスリット２８を植物の取付対象部となる茎（幹）１４や枝１６の側部へ当て、スリット２８内へ押し込み、自由端２７を変形させて中心穴２６内へ入れる。 Next, how to use the reflective material 20 will be described.
First, as shown in FIG. 4, the original plate 30 is cut from the reflective member 31.
The slit 28 of the original plate 30 is applied to the side portion of the stem (trunk) 14 or the branch 16 to be attached to the plant, pushed into the slit 28, and the free end 27 is deformed and inserted into the center hole 26.

この状態から、係合凸部３４側の端縁３３を係合凹部３５側の端縁３３の上へ重ね、さらに係合凸部３４を係合凹部３５の上へ重ね、係合凸部３４を指Ｆ（又は手袋の指部Ｇ）で押すと、係合凸部３４と係合凹部３５が係合する。
これにより、反射材２０は略円錐形の立体形状となり、かつ茎（幹）１４又は枝１６は、中心穴２６内へ自由端２７の弾性変形により弾力的に支持されることにより、直接固定される。 From this state, the end edge 33 on the engaging convex portion 34 side is overlapped on the edge edge 33 on the engaging concave portion 35 side, and the engaging convex portion 34 is further overlapped on the engaging concave portion 35, and the engaging convex portion 34 is overlapped. Is pressed with the finger F (or the finger portion G of the glove), the engaging convex portion 34 and the engaging concave portion 35 are engaged.
As a result, the reflector 20 has a substantially conical three-dimensional shape, and the stem (trunk) 14 or branch 16 is directly fixed into the center hole 26 by being elastically supported by the elastic deformation of the free end 27. NS.

このように、円形の反射面２１と、その中心に形成される中心穴２６と、この中心穴から径方向外方に達する分離部２８とを備え、植物の取付対象部を分離部２８から中心穴２６へ密に入れることにより、植物の取付対象部へ直接着脱自在に取付けた。
このため、反射材２０を植物の反射光を必要とする場所へ、簡単かつ迅速に設置できる。その結果、最適な場所で十分な光量の反射光を照射可能になる。しかも、軽量にできるので植物への直接取付が可能になり、かつ安価に製造できる。 As described above, the circular reflecting surface 21, the center hole 26 formed at the center thereof, and the separating portion 28 extending radially outward from the center hole are provided, and the plant mounting target portion is centered from the separating portion 28. By closely inserting it into the hole 26, it was directly and detachably attached to the attachment target portion of the plant.
Therefore, the reflector 20 can be easily and quickly installed in a place where the reflected light of the plant is required. As a result, it becomes possible to irradiate a sufficient amount of reflected light at an optimum location. Moreover, since it can be made lightweight, it can be directly attached to a plant and can be manufactured at low cost.

また、中心穴２６は、径方向へ放射状に延びる複数の中心穴スリット２３を周囲に備えるので、中心穴２６の周囲部分が変形自由な自由端２７となる。このため、植物の取付対象部を中心穴２６へ密に入れても、自由端２７の変形により植物の取付対象部を支持するので、植物の取付対象部に対する反射材２０の直接取付を可能にするとともに、植物の取付対象部を傷つけないように保護できる。 Further, since the center hole 26 is provided with a plurality of center hole slits 23 extending radially in the radial direction around the center hole 26, the peripheral portion of the center hole 26 becomes a freely deformable free end 27. Therefore, even if the plant mounting target portion is densely inserted into the center hole 26, the plant mounting target portion is supported by the deformation of the free end 27, so that the reflector 20 can be directly mounted on the plant mounting target portion. At the same time, it is possible to protect the plant attachment target part from being damaged.

さらに、分離部２８を挟んで、対向する一対の端縁３３を重ねることにより、略円錐形の立体形状をなす反射材２０としたので、植物に対する固定と同時に反射材２０を略円錐形の立体形状にすることができる。 Further, by overlapping the pair of opposite edge 33s with the separating portion 28 sandwiched between them, the reflective material 20 has a substantially conical three-dimensional shape. Can be shaped.

また、重ね合わされた端縁３３は、それぞれに設けられた係合凸部３４と係合凹部３５により結合されるので、分離部２８を容易に連結して閉じることができる。 Further, since the overlapped end edges 33 are connected by the engaging convex portion 34 and the engaging concave portion 35 provided respectively, the separating portion 28 can be easily connected and closed.

そのうえ、係合凸部３４は、係合凹部３５へ重ねられた状態で、押し込むことにより係合凹部３５へ係合されるので、簡単かつ迅速に係合でき、作業性が向上する。特に、係合部の大きさを、手袋の指部Ｇで押すことができる程度にすれば、手袋を外さずに係合作業ができるので、光制御部材２０の取付作業が効率化する。 Further, since the engaging convex portion 34 is engaged with the engaging concave portion 35 by pushing it in a state of being overlapped with the engaging concave portion 35, it can be easily and quickly engaged and the workability is improved. In particular, the size of the engagement portion, if enough to be pressed with a finger portion G of the glove, since it is engaged work without removing the glove, mounting operation of the light control member 20 is more efficient.

また、本願発明における反射材の製法は、平板状の反射性部材３１から円板状の原板３０をカットするとともに、この原板は、中心穴２６と、この中心穴から径方向外方へ延びて外周へ達する分離部２８とを同時に形成し、その後、この分離部２８を挟む一対の端縁３３を重ね合わせることにより、略円錐形の立体形状にすることを特徴とする。
このようにすると、平板状の部材をワンパンチでカットするだけですむので、製造が容易かつ短時間で済むことになり、製造コストも安価になる。 Further, in the method for producing a reflective material in the present invention, a disk-shaped original plate 30 is cut from a flat plate-shaped reflective member 31, and the original plate extends radially outward from the center hole 26 and the central hole. It is characterized in that a separating portion 28 reaching the outer periphery is formed at the same time, and then a pair of end edges 33 sandwiching the separating portion 28 are overlapped to form a substantially conical three-dimensional shape.
In this way, since it is only necessary to cut the flat plate-shaped member with one punch, the manufacturing can be completed easily and in a short time, and the manufacturing cost can be reduced.

また、分離部２７を挟む一対の端縁３３のうち、一方の端縁３３の近くに設けられた係合凸部３４と、他方に設けられた係合凹部３５を、前記原板３０の形成と同時に形成するとともに、
この係合凸部３４を係合凹部３５へ重ね合わせて、係合凸部３４を押し込むことにより、係合凸部３４を係合凹部３５に係合するので、平板状の原板３０を略円錐形の立体形状をなす光制御部材２０を容易に形成できるとともに、係合も簡単にすることができる。 Further, of the pair of end edges 33 that sandwich the separation portion 27, the engaging convex portion 34 provided near one end edge 33 and the engaging concave portion 35 provided on the other are formed of the original plate 30. At the same time as forming
By superimposing the engaging convex portion 34 on the engaging concave portion 35 and pushing the engaging convex portion 34, the engaging convex portion 34 is engaged with the engaging concave portion 35 , so that the flat plate-shaped original plate 30 is substantially conical. The optical control member 20 having a three-dimensional shape can be easily formed, and the engagement can be simplified.

なお、本実施形態では、複数の係合凹部３５を設けてある。したがって、係合凹部３５を選択して係合凸部３４を係合すると、円錐形状が変化し、反射面２１の傾斜角度θ（図２）が変化する。すなわち、端縁３３から遠い係合凹部３５と係合すると傾斜角度がきつくなる。したがって、反射面２１の傾斜角度θを調整可能となり、使用目的に応じて反射光の光量を調整する自由度を大きくできる。 In this embodiment, a plurality of engaging recesses 35 are provided. Therefore, when the engaging concave portion 35 is selected and the engaging convex portion 34 is engaged, the conical shape changes and the inclination angle θ (FIG. 2) of the reflecting surface 21 changes. That is, when engaged with the engaging recess 35 far from the edge 33, the inclination angle becomes tight. Therefore, the inclination angle θ of the reflecting surface 21 can be adjusted, and the degree of freedom for adjusting the amount of reflected light can be increased according to the purpose of use.

その後、必要により茎（幹）１４や枝１６の取付対象部に対する反射材２０の取付角度を調整する等すれば、反射材２０の内面２２による集光及び外面２４による拡散光により、果実１２の熟成や植物全体の育成が促進される。
また、植物の成長に応じて、外面２４の位置を茎（幹）１４や枝１６の長さ方向に沿って調整して、反射光の最適化を図ることができる。 After that, if necessary, the mounting angle of the reflective material 20 with respect to the mounting target portion of the stem (trunk) 14 or the branch 16 is adjusted, and the light collected by the inner surface 22 of the reflective material 20 and the diffused light by the outer surface 24 of the reflective material 20 causes the fruit 12 to grow. Maturation and growth of the whole plant are promoted.
Further, the position of the outer surface 24 can be adjusted along the length direction of the stem (trunk) 14 and the branch 16 according to the growth of the plant to optimize the reflected light.

なお、本願は上記実施形態に限らず、種々変形可能である。
例えば、図７に示すように、反射面２１を階段状にすれば、反射効率を変えずに全体を薄くすることができる。 The present application is not limited to the above embodiment, and various modifications can be made.
For example, as shown in FIG. 7, if the reflecting surface 21 has a stepped shape, the entire surface can be thinned without changing the reflection efficiency.

また、図８に示すように、反射面２１を曲面状にすることもできる。このようにすれば、特定の照射ポイントに向けた集光量をより大きくすることができる。符号Ｏは反射面２１をなす凹曲面の中心である。
なお、図７及び８の例は、いずれもプレス成形により形状を成形する必要がある。但し、これらの例でも、ワンパンチで中心穴２６、中心穴スリット２３、スリット２８、係合凸部３４、係合凹部３５の形成が可能である。
Further, as shown in FIG. 8, the reflecting surface 21 can be curved. In this way, the amount of light collected toward a specific irradiation point can be increased. Reference numeral O is the center of the concave curved surface forming the reflecting surface 21.
In each of the examples of FIGS. 7 and 8, it is necessary to form the shape by press molding. However, even in these examples, the center hole 26, the center hole slit 23, the slit 28, the engaging convex portion 34, and the engaging concave portion 35 can be formed with one punch.
