Description

本発明は電気光学装置、保持枠体及び電子機器に係り、特に、少なくとも一部が金属板よりなる保持枠体に関する。   The present invention relates to an electro-optical device, a holding frame, and an electronic apparatus, and more particularly, to a holding frame that is at least partially made of a metal plate.

一般に、電気光学装置である液晶表示装置としては、液晶表示パネルを合成樹脂や金属板よりなるフレームに装着したものが知られており、このフレームを介して液晶表示パネルを電子機器に搭載するようにしている。フレームとしては、液晶表示パネルを下方より支持する下フレーム若しくは支持フレームと、液晶表示パネルを観察側より保持する上フレーム若しくは保持フレームとがあり、液晶表示装置としては、これらの上下のフレームによって液晶表示パネルが挟持された状態とされる構成が知られている(たとえば、以下の特許文献1及び2参照)。   In general, a liquid crystal display device which is an electro-optical device is known in which a liquid crystal display panel is mounted on a frame made of a synthetic resin or a metal plate, and the liquid crystal display panel is mounted on an electronic device via the frame. I have to. The frame includes a lower frame or a support frame that supports the liquid crystal display panel from below, and an upper frame or a holding frame that holds the liquid crystal display panel from the observation side. A configuration in which the display panel is sandwiched is known (for example, see Patent Documents 1 and 2 below).

ところで、近年、携帯電話機や携帯型情報端末などの電子機器では小型化、薄型化がますます強く要請されるようになってきており、その結果、上記の電子機器に搭載される前述の液晶表示装置などのフレーム構造も薄型化せざるを得ないことから、耐衝撃性などを確保するためのフレーム強度を維持することが難しい状況にある。このため、フレーム構造として金属板よりなる金属枠を用いる場合が増えてきている。   Incidentally, in recent years, there has been an increasing demand for downsizing and thinning of electronic devices such as mobile phones and portable information terminals, and as a result, the above-described liquid crystal display mounted on the above electronic devices. Since the frame structure of the apparatus or the like must be thinned, it is difficult to maintain the frame strength for ensuring impact resistance and the like. For this reason, the case where the metal frame which consists of a metal plate is used as a frame structure is increasing.

しかしながら、金属板よりなる金属枠を用いる場合でも薄型化と耐衝撃性を両立しなければならない状況には変わりがないので、最近の電気光学装置の薄型化のさらなる進展により、金属板を用いた場合でも十分な剛性を確保することが難しくなってきている。   However, even when a metal frame made of a metal plate is used, the situation in which both thinning and impact resistance must be compatible remains unchanged. Even in such cases, it has become difficult to ensure sufficient rigidity.

また、板材で構成される箱体の補強構造としては上記特許文献3に示されるものがあるが、配電盤などといった小型化の要請の弱いものでは有効であるものの、リブを設けることでコンパクト性が犠牲になる反面、剛性向上効果が低いことから、小型化、薄型化の要請の強い携帯型電子機器に用いる場合には不十分である。   Further, as a reinforcing structure for a box made of a plate material, there is a structure shown in the above-mentioned Patent Document 3, but it is effective for a device with a small demand for downsizing such as a switchboard, but by providing ribs, compactness can be achieved. Although sacrificed, the rigidity improvement effect is low, so that it is insufficient when used in portable electronic devices that are strongly demanded to be reduced in size and thickness.

さらに、金属板で構成される保持枠体は樹脂成型で形成される樹脂フレームに比べて形状の自由度が低く、壁の形状を任意に形成することが難しく、また、液晶表示パネルを支持するための段差面を自由に形成することができないという問題点もある。   Furthermore, the holding frame made of a metal plate has a lower degree of freedom in shape than a resin frame formed by resin molding, it is difficult to arbitrarily form the wall shape, and supports the liquid crystal display panel. Therefore, there is a problem that the stepped surface cannot be freely formed.

そこで、本発明は上記問題点を解決するものであり、小型化、薄型化の要請に反することなく十分な強度を得ることが可能な保持枠体及びこれを用いた電気光学装置を提供することにある。   Therefore, the present invention solves the above-described problems, and provides a holding frame body capable of obtaining sufficient strength without contradicting the demand for downsizing and thinning, and an electro-optical device using the holding frame body. It is in.

Although it can be formed of the same metal plate and can be configured so as not to hinder downsizing and thinning, the rigidity of the wall can be greatly increased in all directions. Therefore, it is possible to meet the demand for downsizing and thinning while ensuring the impact resistance as an electro-optical device.

That is, the peripheral wall 132 is folded back from the lower side to the upper side, is returned to the inner side, and is folded back upward again. The laminated wall is formed by laminating a plurality of layers with folded portions 130x and 130y at both inner and outer ends. It has become.

また、周囲壁132では、外側の折り返し部130xが高さ方向にほぼ同一の平面位置に設けられているのに対して、周囲壁132の高さ方向の中間位置において、上層の内側の折り返し部130yより内側に下層の折り返し部130yが配置され、当該下層の金属板が内側へ張り出した部分があり、当該部分の表面が段差面となって上記パネル支持面132bを構成している。すなわち、周囲壁132では下部にある複数の層の内外方向の幅よりも上部の複数の層の内外方向の幅が小さく構成され、下部と上部の間に幅の差異によって段差面が構成されている。   In the peripheral wall 132, the outer folded portion 130x is provided at substantially the same planar position in the height direction, whereas the inner folded portion in the upper layer is provided at the intermediate position in the height direction of the peripheral wall 132. A lower folded portion 130y is disposed on the inner side of 130y, and there is a portion where the lower metal plate protrudes inward, and the surface of the portion forms a step surface to constitute the panel support surface 132b. That is, in the peripheral wall 132, the inner and outer widths of the upper layers are smaller than the inner and outer widths of the lower layers, and a step surface is formed by the difference in width between the lower and upper portions. Yes.

さらに、周囲壁132の外面には外側の折り返し部130xが一部内側へずれた位置に形成されている部分があり、当該部分に形成された凹部が上記係合穴132tを形成している。なお、当該係合穴132tが、折り返し部130xの位置の変更ではなく、金属板に形成した孔で形成されるようにしてもよい。   Further, the outer surface of the peripheral wall 132 has a portion where the outer folded portion 130x is formed at a position partially displaced inward, and the recess formed in the portion forms the engagement hole 132t. Note that the engagement hole 132t may be formed by a hole formed in the metal plate instead of changing the position of the folded portion 130x.

一方、図2(b)に示すように、保持フレーム140においては、上面部141が一枚の金属板で構成されるとともに、この金属板の周縁部分が上面部141の周囲に張り出して、電気光学パネル120の厚み方向下方へ折り返され、この折り返し部を内外両側に備えた態様で積層することで周囲壁142が構成されている。すなわち、周囲壁142は上方から外側で下方へ折り返され、内側に戻って再び下方へ折り返されるというように、内外両端にそれぞれ折り返し部140x、140yを備え、複数層が積層されてなる積層壁となっている。   On the other hand, as shown in FIG. 2B, in the holding frame 140, the upper surface portion 141 is composed of a single metal plate, and the peripheral portion of the metal plate protrudes around the upper surface portion 141, The peripheral wall 142 is configured by folding the optical panel 120 downward in the thickness direction and stacking the folded portions on both the inner and outer sides. That is, the peripheral wall 142 is folded back from the upper side to the lower side, returned to the inner side, and folded back downward again, so that the inner and outer ends have folded portions 140x and 140y, respectively, and a laminated wall formed by laminating a plurality of layers. It has become.

また、周囲壁142の外面には外側の折り返し部140yが一部内側へずれた位置に形成されている部分があり、当該部分によって形成された凸部が上記係合突起142tを形成している。なお、当該係合突起142tが、折り返し部140yの位置の変更ではなく、金属板の一部を内側に張り出させた突片部によって構成されるようにしてもよい。   Further, the outer surface of the peripheral wall 142 has a portion where the outer folded portion 140y is formed at a position partially displaced inward, and the convex portion formed by the portion forms the engaging protrusion 142t. . Note that the engagement protrusion 142t may be configured by a projecting piece portion in which a part of the metal plate protrudes inward, instead of changing the position of the folded portion 140y.

Then, the metal plate is moved inward and outward (along the surface of the electro-optical panel 120) by providing folded portions 130x and 130y at the upper and lower ends, respectively. The peripheral wall 132 which is a laminated wall laminated in the same direction) is configured. Here, the panel support surface 132b is formed by an upper folded portion 130y formed lower than the upper edge 132a of the peripheral wall 132. The engagement hole 132t is configured by a hole formed in the outer metal plate.

一方、図3(b)に示すように、保持フレーム140においても、上面部141(上記表示窓140aが開口した金属板で構成される。)を構成する一枚の金属板が上面部141より外側に張り出して下側へ折り曲げられて下方へ伸び、下部で外側へ折り返されて上方へ伸びた後、上部で外側へ折り返されて再び下方へ伸びるというように、上下両端にそれぞれ折り返し部140xと140yが設けられることにより、金属板が内外(電気光学パネル120の表面に沿った方向)に積層された積層壁である周囲壁142が構成されている。ここで、上記係合突起142tは、最も内側の金属板を切り欠いて内側に突出させた突片部によって構成されている。   On the other hand, as shown in FIG. 3B, also in the holding frame 140, a single metal plate constituting the upper surface portion 141 (comprised of a metal plate having the display window 140 a opened) is formed from the upper surface portion 141. Each of the folded portions 140x extends to the upper and lower ends so as to project outward and bend downward and extend downward, bend outward at the lower portion and extend upward, and then bend outward at the upper portion and extend downward again. By providing 140y, a peripheral wall 142, which is a laminated wall in which metal plates are laminated inside and outside (direction along the surface of the electro-optical panel 120), is configured. Here, the engaging protrusion 142t is constituted by a protruding piece portion that is cut out from the innermost metal plate and protrudes inward.

Note that the difference in height between the peripheral walls 132 and 133 or the peripheral walls 142 and 143 can be formed by changing the number of stacked layers in the example shown in FIG. 2, and in the example shown in FIG. It can be formed by changing the position (height) of the folded portions 130y, 140y. In the second embodiment, the peripheral walls 132 and 142 are formed by folding outside the bottom surface portion 131 or the top surface portion 141 in both cases. Good. These points are the same in the following configuration examples.

[Configuration near the corner]
Next, a configuration example of the corner portion of the peripheral wall according to the present embodiment will be described with reference to FIGS. 4 to 13. In addition, although each structural example demonstrated below shows the example which comprises the support frame 130, it can also be used for the holding | maintenance frame 140 about the same structure. Further, the detailed structure (the panel support surface 132b, the engagement hole 132t, the engagement protrusion 142t, etc.) shown in FIG. 2 or 3 is omitted in the following drawings and description. Furthermore, in each figure, what is shown by the alternate long and short dash line is a partial development view of the metal plate, the alternate long and short dash line indicates the outer edge shape of the metal plate, and the alternate long and two short dashes line indicates the folding line or the folding line of the metal plate. . Moreover, the drawing shown by the solid line in the drawing drawn at the tip of the arrow with respect to the partially developed view is a partial plan view near the corner portion of the support frame 130 after the metal plate is bent or folded back.

(第1構成例)最初に図4を参照して上記周囲壁132の角部近傍の構成及び製造方法について説明する。この構成例は図2に示す積層構造を有する周囲壁の角部を形成するための構造を示すものである。当該構成例では、矩形状の底面部131の隣接する2辺からそれぞれ外側へ張り出した金属板の張り出し領域132A、132Bを別々に設け、各張り出し領域132A、132Bにそれぞれ底面部131側より順に周囲壁132の平面方向に沿った幅に相当する幅を有する屈折片部132A1,132A2、・・・及び132B1、132B2、・・・を設定する。当該張り出し領域132Aと132Bの端縁132Ap、132Bpは、外側角点Oから外側へ向けて相互に分離されて伸び、いずれも底面部131より外側に順次設けられる屈折片部毎に外側へ向けて交互に逆向きに傾斜した端縁部132Ap1、132Ap2、・・・、132Bp1、132Bp2、・・・を備えている。   (First Configuration Example) First, the configuration and manufacturing method in the vicinity of the corner portion of the peripheral wall 132 will be described with reference to FIG. This configuration example shows a structure for forming a corner portion of the peripheral wall having the laminated structure shown in FIG. In this configuration example, the metal plate overhanging areas 132A and 132B projecting outward from the two adjacent sides of the rectangular bottom surface 131 are provided separately, and each of the overhanging areas 132A and 132B is sequentially surrounded from the bottom surface 131 side. Refraction pieces 132A1, 132A2,... And 132B1, 132B2,... Having a width corresponding to the width along the plane direction of the wall 132 are set. Edges 132Ap and 132Bp of the overhanging regions 132A and 132B are separated from each other and extend outward from the outer corner point O, and both are directed outward for each refracting piece portion sequentially provided outward from the bottom surface portion 131. , 132Bp1, 132Bp2,... Alternately inclined in opposite directions.

上記のように構成された金属板のうち、底面部131の外側に隣接する屈折片部132A1及び132B1を外側角点Oを通過する折り返し線で底面部131の外周部上に折り返す。このとき、屈折片部132A1の端縁部132Ap1と屈折片部132B1の端縁部132Bp1とが整合し、これらの端縁部同士が密接するようになっている。このとき、上記外側角点Oは上記端縁部132Ap1、132Bp1の最外端に配置される。次に、屈折片部132A2及び132B2を逆向きに上記屈折片部132A1及び132B1上に折り返す。この場合にも、角部132pにおいては端縁部132Ap2と132Bp2とが整合して密接する。さらに、これ以後、張り出し領域132Aの屈折片部132A3・・・及び張り出し領域132Bの屈折範囲132B3・・・を順次に折り返していくことで、上記外側角点Oを最外端とする角部132pを備えた周囲壁132が形成される。なお、本明細書において「密接する」とは、僅かな隙間を介して対向する場合をも含むものとする。   Of the metal plate configured as described above, the refracting piece portions 132A1 and 132B1 adjacent to the outside of the bottom surface portion 131 are folded back on the outer peripheral portion of the bottom surface portion 131 by a folding line passing through the outer corner point O. At this time, the end edge portion 132Ap1 of the refracting piece portion 132A1 and the end edge portion 132Bp1 of the refracting piece portion 132B1 are aligned, and these end edge portions are in close contact with each other. At this time, the outer corner point O is disposed at the outermost end of the end edge portions 132Ap1 and 132Bp1. Next, the refracting pieces 132A2 and 132B2 are folded back on the refracting pieces 132A1 and 132B1 in the opposite direction. Also in this case, the end portions 132Ap2 and 132Bp2 are aligned and closely contacted at the corner portion 132p. Further thereafter, by sequentially folding back the refracting piece portions 132A3 of the overhanging region 132A and the refraction range 132B3 of the overhanging region 132B, the corner portion 132p having the outer corner point O as the outermost end is formed. A peripheral wall 132 is formed. In the present specification, “closely” includes a case where they face each other through a slight gap.

上記のように構成すると、周囲壁132の角部132pでは、上記複数の端縁部132Ap1、132Ap2・・・が積層されてなる端面132p1と、上記複数の端縁部132Bp1、132Bp2・・・が積層されてなる端面132p2とがそれぞれ略平坦に形成されるとともに、相互に密接した状態となる。したがって、隣接する辺が交差する角部132pにおいても周囲壁132の一体性を確保することができ、周囲壁132の収容機能、位置決め機能、保持機能などを支障なく発揮できるように構成することが可能である。特に、周囲壁132に外側から内側へ応力が加わったときに端面132p1と132p2とが当接して支えあうため、周囲壁132の剛性を高めることができる。   If comprised as mentioned above, in the corner | angular part 132p of the surrounding wall 132, end surface 132p1 formed by laminating | stacking several said edge part 132Ap1, 132Ap2 ..., and several said edge part 132Bp1, 132Bp2 ... will be mentioned. The laminated end face 132p2 is formed substantially flat and is in close contact with each other. Therefore, it is possible to ensure the integrity of the peripheral wall 132 even at the corner 132p where adjacent sides intersect, and to be able to exhibit the accommodation function, positioning function, holding function, and the like of the peripheral wall 132 without hindrance. Is possible. In particular, when stress is applied to the peripheral wall 132 from the outside to the inside, the end faces 132p1 and 132p2 come into contact with each other and support each other, so that the rigidity of the peripheral wall 132 can be increased.

(第2構成例)図5に示す構成例は図3に示す積層構造を有する周囲壁132の角部を構成する例を示すものである。この構成では、内側角点Iから外側へ分離して伸びる端縁132Ap及び132Bpをそれぞれ備えた張り出し領域132Aと132Bを備えている。そして、各屈折片部132A1、132A2・・・及び132B1、132B2・・・の端縁部132Ap1、132Ap2・・・及び端縁部132Bp1、132Bp2・・・は、それぞれが金属板の厚み方向に交互に逆方向に斜めにカットされるとともに、順次に外側へ向けて徐々に張り出すように構成されている。   (Second Configuration Example) The configuration example shown in FIG. 5 shows an example in which the corner portion of the peripheral wall 132 having the laminated structure shown in FIG. 3 is configured. In this configuration, overhanging regions 132A and 132B having end edges 132Ap and 132Bp extending separately from the inner corner point I are provided. .. And 132B1, 132B2... And edge portions 132Bp1, 132Bp2... And edge portions 132Bp1, 132Bp2... Are alternately arranged in the thickness direction of the metal plate. In addition to being cut obliquely in the opposite direction, the projection is gradually projected outward.

上記の結果、底面部131の外側に隣接する屈折片部132A1、132B1を底面部131側に屈折させて立設させ、次の屈折片部132A2、132B2を反対の外側に折り返して外側に重ね、さらに次の屈折片部132A3、132B3を内側に折り返して外側に重ねるといったように、順次に外側に交互に逆に折り返して重ねていくことで、図3に示す構造の積層壁である周囲壁132を形成することができる。   As a result of the above, the refractive piece portions 132A1 and 132B1 adjacent to the outside of the bottom surface portion 131 are refracted to the bottom surface portion 131 side, and the next refractive piece portions 132A2 and 132B2 are folded back to the opposite outer side and overlapped outside. Further, the peripheral wall 132, which is a laminated wall having the structure shown in FIG. 3, is formed by sequentially folding the next refracting pieces 132A3 and 132B3 back to the inner side and overlapping the outer side alternately. Can be formed.

この構成例では、周囲壁132の角部132pにおいて、張り出し領域132Aで形成された周囲壁の上記端縁部132Ap1、132Ap2・・・が積層されてなる端面132p1と、同様に張り出し領域132Bで形成された周囲壁の上記端縁部132Bp1、132Bp2・・・が積層されてなる端面132p2がそれぞれ略平坦に形成されるとともに、相互に密接した状態となる。したがって、隣接する辺が交差する角部132pにおいても周囲壁132の一体性を確保することができ、周囲壁132の収容機能、位置決め機能、保持機能などを支障なく発揮できるように構成することが可能である。特に、周囲壁132に対して外側から内側に応力が加えられたときに上記端面132p1と132p2とが当接しあって周囲壁132を支えるので、高い剛性を得ることができる。   In this configuration example, in the corner portion 132p of the peripheral wall 132, the end surface 132p1 formed by laminating the edge portions 132Ap1, 132Ap2,... Of the peripheral wall formed in the overhang region 132A is formed similarly in the overhang region 132B. The end surfaces 132p2 formed by laminating the edge portions 132Bp1, 132Bp2,... Of the surrounding walls are formed substantially flat and are in close contact with each other. Therefore, it is possible to ensure the integrity of the peripheral wall 132 even at the corner 132p where adjacent sides intersect, and to be able to exhibit the accommodation function, positioning function, holding function, and the like of the peripheral wall 132 without hindrance. Is possible. In particular, when stress is applied from the outside to the inside with respect to the surrounding wall 132, the end faces 132p1 and 132p2 come into contact with each other to support the surrounding wall 132, so that high rigidity can be obtained.

(第3構成例)図6に示す構成例では、矩形状の底面部131の隣接する2辺から張り出した金属板の張り出し領域132A、132Bを別々に設け、各張り出し領域132A、132Bにそれぞれ底面部131側より順に周囲壁132の平面方向に沿った幅に相当する幅を有する複数の屈折片部132A1、132A2・・・及び132B1、132B2・・・を外側に向けて順次に設定し、これらの各屈折片部を底面部131の外周部上に折り重ねて周囲壁132を形成する点では第1構成例と同様である。   (Third Configuration Example) In the configuration example shown in FIG. 6, metal plate overhang regions 132A and 132B overhanging from two adjacent sides of the rectangular bottom surface portion 131 are provided separately, and the bottom surfaces are respectively provided in the overhang regions 132A and 132B. A plurality of refractive piece portions 132A1, 132A2,... And 132B1, 132B2... Having a width corresponding to the width along the planar direction of the peripheral wall 132 are sequentially set outward from the portion 131 side. Each of the refracting piece portions is folded on the outer peripheral portion of the bottom surface portion 131 to form the peripheral wall 132, which is similar to the first configuration example.

当該張り出し領域132Aと132Bの端縁132Ap、132Bpは、外側角点Oから外側へ向けて分離されて伸び、いずれも底面部131より外側に順次設けられる二つの屈折片部毎に、外側角点Oと同位置に配置された端縁部と、これより離間する側に引き込まれた位置に配置された端縁部とが交互に設けられている。これによって、張り出し領域132Aに属する屈折片部132A1、132A2・・・と張り出し領域132Bに属する屈折片部132B1、132B2・・・とが2枚ずつ交互に重なる態様で角部132pが構成される。したがって、角部132pにおいては屈折片部132A1、132A2・・・と屈折片部132B1、132B2・・・とが交互に嵌合する態様で積層され、より具体的には角部132pにおいて一方の端面132p1と他方の端面132p2とが平面視矩形状(図示正方形状)の領域において互い違いに噛み合った状態となることから、角部132pの一体性をさらに高めることができる。特に、周囲壁132に対して上方から下方へ、或いは、下方から上方へ向かう方向に加わる応力に対しても剛性を高めることができる。   Edges 132Ap and 132Bp of the overhanging regions 132A and 132B are separated and extended outward from the outer corner point O, and the outer corner points are provided for each of the two refracting piece portions sequentially provided outside the bottom surface portion 131. The edge part arrange | positioned in the same position as O, and the edge part arrange | positioned in the position pulled in the side farther from this are alternately provided. As a result, the corner portions 132p are configured in such a manner that the refractive piece portions 132A1, 132A2,... Belonging to the protruding region 132A and the refractive piece portions 132B1, 132B2,. Therefore, in the corner portion 132p, the refracting piece portions 132A1, 132A2,... And the refracting piece portions 132B1, 132B2,... Are alternately stacked, and more specifically, one end face in the corner portion 132p. Since 132p1 and the other end surface 132p2 are alternately engaged in a rectangular shape (square shape in the figure) in plan view, the integrity of the corner portion 132p can be further improved. In particular, the rigidity can be increased even with respect to the stress applied to the surrounding wall 132 from the upper side to the lower side or from the lower side to the upper side.

なお、本構成例では2層ごとに交互に両張り出し領域に属する屈折片部が積層されているが、各張り出し領域132A,132Bの端縁を各屈折片部の一つの端縁部ごとに交互に外側角点O側に出没させる(端縁部を一つおきに突出させる)ことで、角部132pにおいて1層ずつ交互に屈折片部が積層されるように構成することも可能である。   In this configuration example, the refracting pieces belonging to the two overhanging regions are alternately laminated every two layers, but the edge of each of the overhanging regions 132A and 132B is alternated for every one edge of each refracting piece. It is also possible to make it so that the refractive piece portions are alternately laminated one by one in the corner portion 132p by projecting toward and away from the outer corner point O (by projecting every other edge portion).

(第4構成例)図7に示す構成例では、矩形状の底面部131の隣接する2辺から張り出した金属板の張り出し領域132A、132Bを別々に設け、各張り出し領域132A、132Bにそれぞれ底面部131側より順に周囲壁132の平面方向に沿った幅に相当する幅を有する複数の屈折片部132A1、132A2・・・及び132B1、132B2・・・を外側に向けて順次に設定し、底面部131の外縁上において立設した状態に外側へ向けて順次に折り重ねて周囲壁132を形成する点では第2構成例と同様である。   (Fourth Configuration Example) In the configuration example shown in FIG. 7, metal plate projecting regions 132A and 132B projecting from two adjacent sides of the rectangular bottom surface portion 131 are separately provided, and the bottom surfaces are respectively provided in the projecting regions 132A and 132B. A plurality of refracting pieces 132A1, 132A2,... And 132B1, 132B2,... Having a width corresponding to the width along the planar direction of the peripheral wall 132 are sequentially set from the side of the portion 131 toward the outside, and the bottom surface. It is the same as that of the second configuration example in that the peripheral wall 132 is formed by sequentially folding the portion 131 toward the outside while standing on the outer edge of the portion 131.

当該張り出し領域132Aと132Bの端縁132Ap、132Bpは、内側角点Iから外側へ向けて分離されて伸び、いずれも底面部131より外側に順次設けられる二つの屈折片部毎に、内側角点Iより離れるに従って順次に他方の張り出し領域の二つの屈折片部の積層厚みと同幅だけ端縁部が突出するように構成されている。これによって、張り出し領域132Aに属する屈折片部132A1、132A2・・・の端縁部と張り出し領域132Bに属する屈折片部132B1、132B2・・・の端縁部とが2枚ずつ交互に突き合わされる態様で角部132pが構成される。したがって、角部132pにおいては屈折片部132A1、132A2・・・と屈折片部132B1、132B2・・・とが交互に嵌合する態様で積層されることから、角部132pの一体性をさらに高めることができる。   Edges 132Ap and 132Bp of the overhanging regions 132A and 132B are separated and extended outward from the inner corner point I, and both of the inner corner points are provided for each of the two refracting pieces sequentially provided outside the bottom surface portion 131. As the distance from I increases, the end edge portion protrudes sequentially in the same width as the thickness of the two refracting piece portions in the other overhang region. As a result, the edge portions of the refracting pieces 132A1, 132A2,... Belonging to the overhanging region 132A and the edge portions of the refracting piece portions 132B1, 132B2,. In this manner, the corner portion 132p is configured. Therefore, in the corner portion 132p, the refractive piece portions 132A1, 132A2,... And the refractive piece portions 132B1, 132B2,. be able to.

なお、本構成例では2層ごとに両張り出し領域に属する屈折片部が交互に突き合わされるように構成されているが、各張り出し領域132A,132Bの端縁を各屈折片部の一つの端縁部ごとに他方の屈折片部の1層の厚み分だけ順次に突出するように構成することで、角部132pにおいて1層ずつ交互に屈折片部が突き合わされるように構成することも可能である。   In this configuration example, the refractive piece portions belonging to the two protruding regions are alternately abutted every two layers, but the edge of each protruding region 132A, 132B is used as one end of each refractive piece portion. It is also possible to configure so that the refractive piece portions are alternately abutted one by one at the corner portion 132p by sequentially configuring the edge portion by the thickness of one layer of the other refractive piece portion. It is.

(第5構成例)図8に示す構成例では、矩形状の底面部131の隣接する2辺から張り出した金属板の張り出し領域132A、132Bを別々に設け、各張り出し領域132A、132Bにそれぞれ底面部131側より順に周囲壁132の内外方向の厚みに相当する幅を有する複数の屈折片部132A1、132A2・・・及び132B1、132B2・・・を外側に向けて順次に設定し、底面部131の外周部上に折り重ねて周囲壁132を形成する点では第1構成例と同様である。   (Fifth Configuration Example) In the configuration example shown in FIG. 8, metal plate projecting regions 132A and 132B projecting from two adjacent sides of the rectangular bottom surface portion 131 are separately provided, and the bottom surfaces are respectively provided in the projecting regions 132A and 132B. A plurality of refracting pieces 132A1, 132A2,... And 132B1, 132B2,... Having a width corresponding to the thickness in the inner and outer directions of the peripheral wall 132 are sequentially set from the side of the portion 131 toward the outer side. It is the same as that of the first configuration example in that the peripheral wall 132 is formed by being folded on the outer peripheral portion.

また、当該張り出し領域132Aと132Bの端縁は外側角点Oから外側へ向けて分離されて伸び、いずれも底面部131より外側に順次設けられる屈折片部に、外側角点Oと同位置に配置された端縁部と、これより他方の張り出し領域の屈折片部の幅だけ引き込まれた位置に配置された端縁部とが交互に設けられ、これらによって、張り出し領域132Aに属する屈折片部132A1、132A2・・・と張り出し領域132Bに属する屈折片部132B1、132B2・・・とが重なる態様で角部132pが構成される点で上記第3構成例と同様である。   In addition, the end edges of the overhanging regions 132A and 132B are separated and extended outward from the outer corner point O, and both are located at the same position as the outer corner point O on the refracting piece portions sequentially provided outside the bottom surface portion 131. The arranged end edge portions and the end edge portions arranged at the positions drawn by the width of the refracting piece portion of the other overhanging region are alternately provided, and thereby, the refraction piece portions belonging to the overhanging region 132A. Are similar to the third configuration example in that the corner portion 132p is configured in such a manner that 132A1, 132A2,... And the refractive piece portions 132B1, 132B2,.

本構成例では、外側角点Oの内側の底面部131の外周部に屈折片部132A1が折り重ねられ、屈折片部132B1、132B2及び132B3が上記屈折片部132A1の角部に配置される部分を避けるように底面部131の外周部に折り重ねられる。しかしながら、屈折片部132B4の突出部132B4aを突出させるとともに、その先にさらに折り返し突片部132B4b、132B4cを設け、これらを下方に(すなわち、上方への折り重ね積層手順とは逆方向に)折り返した状態で上記屈折片部132A1上に重ねる点で上記構成例とは異なる。その後、屈折片部132A5をその突出部が突出部132B4a上に折り重ねられるように折り返し、屈折片部132B5を角部132pを避けて折り重ねる。   In this configuration example, the refractive piece portion 132A1 is folded on the outer peripheral portion of the bottom surface portion 131 inside the outer corner point O, and the refractive piece portions 132B1, 132B2, and 132B3 are arranged at the corner portions of the refractive piece portion 132A1. Is folded on the outer peripheral portion of the bottom portion 131. However, the protruding portion 132B4a of the refracting piece portion 132B4 is made to protrude, and further folded protruding piece portions 132B4b and 132B4c are provided at the tip thereof, and these are folded downward (that is, in the direction opposite to the upward folding and stacking procedure). In this state, it is different from the above configuration example in that it is superimposed on the refractive piece portion 132A1. Thereafter, the refracting piece portion 132A5 is folded back so that the protruding portion is folded on the protruding portion 132B4a, and the refracting piece portion 132B5 is folded avoiding the corner portion 132p.

上記のように上方へ屈折片部を順次に折り重ねていく途中で或る屈折片部の突片部を逆に下方へ折り返すことで、角部132pにおける端面部132p1と132p2の嵌合構造をより自由に構成することが可能になる。   In the middle of sequentially folding the refracting piece portions upward as described above, the projecting piece portion of a certain refracting piece portion is turned back to the opposite side, so that the fitting structure of the end face portions 132p1 and 132p2 in the corner portion 132p can be obtained. It becomes possible to configure more freely.

なお、本構成例では張り出し領域132Bにのみ上記折り返し突片部を設けたが、張り出し領域132Aに設けてもよく、或いは、張り出し領域132Aと132Bに交互に設けてもよい。   In the present configuration example, the folded protrusions are provided only in the overhanging area 132B, but they may be provided in the overhanging area 132A or alternately in the overhanging areas 132A and 132B.

(第6構成例)図9に示す構成例では、矩形状の底面部131の隣接する2辺から張り出した金属板の張り出し領域132A、132Bを別々に設け、各張り出し領域132A、132Bにそれぞれ底面部131側より順に周囲壁132の内外方向に沿った厚みに相当する幅を有する複数の屈折片部132A1、132A2・・・及び132B1、132B2・・・を外側に向けて順次に設定し、底面部131の外縁上において立設した状態に折り返して周囲壁132を形成する点では第2構成例と同様である。   (Sixth Configuration Example) In the configuration example shown in FIG. 9, metal plate overhang regions 132A and 132B overhanging from two adjacent sides of the rectangular bottom surface portion 131 are provided separately, and the bottom surfaces are respectively provided in the overhang regions 132A and 132B. A plurality of refractive piece portions 132A1, 132A2,... And 132B1, 132B2... Having a width corresponding to the thickness along the inner and outer directions of the peripheral wall 132 are sequentially set from the side of the portion 131 toward the outer side. It is the same as that of the second configuration example in that the peripheral wall 132 is formed by folding it back up on the outer edge of the portion 131.

本構成例では、張り出し領域132A及び132Bにおいてそれぞれ複数の屈折片部が嵌合した構造の角部132pが構成される点で上記第4構成例と同様であるが、張り出し領域132Bの屈折片部132B4に突出部132B4aが設けられ、この突出部132B4aに対して内側角点I側に延長して設けられた突片部132B4b及びその先にさらに接続された突片部132B4cが設けられている点で異なる。すなわち、張り出し領域132Aの屈折片部132A1が底面部131側に立設され、その後、屈折片部132A2が屈折片部132A1の外側に重なるように折り返される一方、張り出し領域132Bの屈折片部132B1、132B2及び132B3が同様に順次に折り重ねられると、屈折片部132A2の突出部132A2aが屈折片部132B1、132B2及び132B3の端縁部の外側に重なるように組み合わされる。さらに、屈折片部132B4が同様にさらに外側に折り重ねられ、その突出部132B4aに延長形成された突片部132B4b及び132B4cを逆に内側角点I側へ向けて順次に折り返して重ねると、屈折片部132A2aの外側に組み合わされる。そして、その外側へ屈折片部132A3及び132A4をさらに折り重ねることで、突片部132A4aが上記突出部132B4a、突片部132B4b及び132B4cの外側に組み合わされる。   This configuration example is similar to the fourth configuration example in that a corner portion 132p having a structure in which a plurality of refraction pieces are fitted in each of the overhang regions 132A and 132B is configured. However, the refraction piece portion of the overhang region 132B is configured. A protrusion 132B4a is provided on 132B4, and a protrusion 132B4b provided to extend toward the inner corner I with respect to the protrusion 132B4a and a protrusion 132B4c further connected to the tip are provided. It is different. That is, the refractive piece portion 132A1 of the overhang region 132A is erected on the bottom surface portion 131 side, and then the refractive piece portion 132A2 is folded back so as to overlap the outside of the refractive piece portion 132A1, while the refractive piece portion 132B1 of the overhang region 132B. Similarly, when 132B2 and 132B3 are sequentially folded, the protrusions 132A2a of the refracting piece portions 132A2 are combined so as to overlap the outer edges of the refracting piece portions 132B1, 132B2, and 132B3. Further, the refracting piece portion 132B4 is similarly folded further outward, and when the protruding piece portions 132B4b and 132B4c extended from the protruding portion 132B4a are sequentially folded back toward the inner corner I side, they are refracted. Combined on the outside of the piece 132A2a. Then, by further folding the refracting piece portions 132A3 and 132A4 to the outside, the protruding piece portion 132A4a is combined with the protruding portion 132B4a and the protruding piece portions 132B4b and 132B4c.

上記のように屈折片部を外側へ順次に折り重ねていく途中で逆に内側に折り重ねる部分を設けることも可能であり、これによって、角部132pの両側の端面部132p1と132p2の嵌合態様をより自由に構成できる。   As described above, it is also possible to provide a portion that folds the refracting piece portion inward in the middle while the refracting piece portion is folded inward, thereby fitting the end face portions 132p1 and 132p2 on both sides of the corner portion 132p. The aspect can be configured more freely.

(第7構成例)図10に示す構成例では、第1構成例と同様に屈折片部を底面部131の外周部上に折り返して上方へ折り重ねていく構造を有するが、張り出し領域132Aの屈折片部132A1、132A2に相互に連続する切り欠き部132A1a、132A2aが設けられ、屈折片部が折り重ねられたときに上記の切り欠き部によって角部132pに凹部が構成される。一方、張り出し領域132Bでは屈折片部132B1、132B2に突出部132B1a、132B2aが設けられ、これらが屈折片部132B1、132B2が折り重ねられたときに屈折片部132A1、132A2の折り重ね部分に構成された上記凹部に嵌合する凸部を構成するようになっている。本構成例では、上記構造上には、さらに屈折片部132A3及び132A4に設けられた突出部132A3a、132A4aと、屈折片部132B3及び132B4に設けられた切り欠き部132B3a、132B4aが上記とは逆の関係で凹凸嵌合する。さらに、その上には、切り欠き部132A5を備えた屈折片部132A5と、突出部132B5aを備えた屈折片部132B5とが嵌合している。   (Seventh Configuration Example) The configuration example shown in FIG. 10 has a structure in which the refracting piece portion is folded over the outer peripheral portion of the bottom surface portion 131 and folded upward as in the first configuration example. The refracting pieces 132A1 and 132A2 are provided with notches 132A1a and 132A2a that are continuous with each other, and when the refracting pieces are folded, a recess is formed in the corner 132p by the notches. On the other hand, in the overhang region 132B, the protruding portions 132B1a and 132B2a are provided in the refracting piece portions 132B1 and 132B2, and these are configured as folded portions of the refracting piece portions 132A1 and 132A2 when the refracting piece portions 132B1 and 132B2 are folded. Further, a convex portion that fits into the concave portion is configured. In this configuration example, the protrusions 132A3a and 132A4a provided on the refraction pieces 132A3 and 132A4 and the notches 132B3a and 132B4a provided on the refraction pieces 132B3 and 132B4 are further opposite to the above. Concave and convex fitting due to the relationship. Furthermore, a refracting piece portion 132A5 having a notch portion 132A5 and a refracting piece portion 132B5 having a protruding portion 132B5a are fitted thereon.

本構成例では、上記のように角部132pにおいて張り出し領域132Aの屈折片部と張り出し領域132Bの屈折片部とが重なるだけでなく相互に嵌合する構造を有するため、角部132pの剛性をさらに高めることができる。   In this configuration example, since the refracting piece portion of the overhanging region 132A and the refracting piece portion of the overhanging region 132B overlap each other at the corner portion 132p as described above, the rigidity of the corner portion 132p is increased. It can be further increased.

(第8構成例)図11に示す構成例は、第2実施形態と同様に張り出し領域132A、132Bの各屈折片部を底面部131の外縁部上に立設させた状態で折り重ねることで周囲壁132を設ける構造に関する。この構成例では、張り出し領域132Aの屈折片部132A1、132A2に切り欠き部132A1a、132A2aを設けるとともに、張り出し領域132Bの屈折片部132B3、132B4にそれぞれ突出部132B3a、132B4aを設けている。   (Eighth Configuration Example) The configuration example shown in FIG. 11 is formed by folding each of the refracting pieces 132A and 132B on the outer edge of the bottom portion 131 in the same manner as in the second embodiment. The present invention relates to a structure in which a peripheral wall 132 is provided. In this configuration example, notches 132A1a and 132A2a are provided in the refracting pieces 132A1 and 132A2 of the overhanging region 132A, and protrusions 132B3a and 132B4a are provided in the refracting pieces 132B3 and 132B4 of the overhanging region 132B, respectively.

本構成例では、張り出し領域132Aについては各屈折片部を外側へ順次に折り返していくことで周囲壁132を形成するが、張り出し領域132Bでは各屈折片部を内側へ順次に折り返して周囲壁を形成する。したがって、張り出し領域132Aでは両張り出し領域の端縁の分岐点である側方角点Kの外側に周囲壁が形成され、張り出し領域132Bでは側方角点Kの内側に周囲壁が形成される。   In this configuration example, the surrounding wall 132 is formed by sequentially folding each refracting piece portion outwardly in the overhanging region 132A, but in the overhanging region 132B, each refracting piece portion is sequentially folded inward to form the surrounding wall. Form. Accordingly, in the overhang region 132A, a peripheral wall is formed outside the side corner point K, which is a branch point of the edges of both overhang regions, and in the overhang region 132B, a peripheral wall is formed inside the side corner point K.

また、本構成例では、上記のように各屈折片部を折り返していくことで、上記切り欠き部132A1a、132A2aで構成される凹部に上記突出部132B3a、132B4aで構成される凸部が嵌合するので、角部132pの剛性をさらに高めることができる。   Further, in this configuration example, by folding each refracting piece portion as described above, the convex portion constituted by the protruding portions 132B3a and 132B4a is fitted into the concave portion constituted by the notched portions 132A1a and 132A2a. Thus, the rigidity of the corner portion 132p can be further increased.

(第9構成例)図12に示す構成例は、側方角点Kの一側の張り出し領域132Aにおいては第2構成例と同様に底面部131の外縁に立設した屈折片部を内外に折り重ねていくことで周囲壁132を構成し、他側の張り出し領域132Bにおいては第1構成例と同様に底面部131の外周部上に折り重ねられた屈折片部を上下に折り重ねていくことで周囲壁132を構成したものである。   (Ninth Configuration Example) In the configuration example shown in FIG. 12, in the projecting region 132A on one side of the side corner point K, the refracting piece portion erected on the outer edge of the bottom surface portion 131 is folded inward and outward in the same manner as in the second configuration example. The surrounding wall 132 is configured by overlapping, and in the overhang region 132B on the other side, the refractive piece portion folded on the outer peripheral portion of the bottom surface portion 131 is folded up and down similarly to the first configuration example. The peripheral wall 132 is configured as described above.

そして、角部132pでは、張り出し領域132Aの屈折片部132A1、132A2に設けられた切り欠き部132A1a、132A2aによって構成される上下に伸びる凹溝中に、張り出し領域132Bの屈折片部132B1〜132B5に設けられた突出部132B1a〜132B5aで構成される上下に伸びる積層構造の凸リブが嵌合することで剛性の高い角部132pが形成される。   In the corner portion 132p, the refraction piece portions 132B1 to 132B5 of the overhang region 132B are inserted into the vertically extending concave grooves formed by the cutout portions 132A1a and 132A2a provided in the refraction piece portions 132A1 and 132A2 of the overhang region 132A. A corner portion 132p having high rigidity is formed by fitting convex ribs of a laminated structure formed by the provided protruding portions 132B1a to 132B5a extending vertically.

(第10構成例)図13に示す構造は、内側角点Iの外側に第2構成例と同様に張り出し領域132A、132Bの双方において底面部131に対して立設した状態で各屈折片部を外側へ順次に折り重ねていくようにしているが、この折り重ねただけでは、角部132pにおいて張り出し領域132Aの端縁で構成される端面132p1と張り出し領域132Bの端縁で構成される端面132p2とが離間したままとなるように構成されている。そこで、この構成例では、その後、角部132pを内側へプレス等で折り曲げ(絞り)加工することで、図示実線で示すように端面132p1、132p2を密接させてある。この構成例では、追加加工を組み合わせることで角部132aの剛性を高めることが可能となっている。   (Tenth Configuration Example) The structure shown in FIG. 13 has each refracting piece portion in a state of standing on the bottom surface portion 131 in both the projecting regions 132A and 132B outside the inner corner point I in the same manner as the second configuration example. Are folded sequentially outward, but only by folding, the end surface 132p1 constituted by the edge of the overhang region 132A and the end surface constituted by the edge of the overhang region 132B at the corner 132p. 132p2 is configured to remain separated. Therefore, in this configuration example, the end surfaces 132p1 and 132p2 are brought into close contact with each other as shown by the solid line in the drawing by bending (drawing) the corner portion 132p inward with a press or the like. In this configuration example, the rigidity of the corner portion 132a can be increased by combining additional processing.
