［第１実施形態］
以下、図面等を参照しながら、本発明の実施形態をさらに詳しく説明する。
図１は、本発明による折り線ヒンジ構造の第１実施形態を示す斜視図である。
図２は、第１実施形態に係る折り線ヒンジ構造を説明する断面図である。
[First Embodiment]
Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings and the like.
FIG. 1 is a perspective view showing a first embodiment of a folding line hinge structure according to the present invention.
FIG. 2 is a cross-sectional view illustrating a folding line hinge structure according to the first embodiment.
（基本構造）
本実施形態に係る折り線ヒンジ構造１０は、図１に示すように、厚板材１の一方の面にヒンジを形成し、折り線ＦＬを境にして、所定の折り角で折ることができる構造であって、高剛性部１１と、低剛性部１２と、折曲案内線１３等とを備えている。
(Basic structure)
As shown in FIG. 1, a folding line hinge structure 10 according to the present embodiment has a structure in which a hinge is formed on one surface of a thick plate material 1 and can be folded at a predetermined folding angle around a folding line FL. And includes a high-rigidity portion 11, a low-rigidity portion 12, a bending guide line 13, and the like.
厚板材１は、ポリプロピレン等の樹脂を用いて成形された気泡ボード、例えば、中空状に膨出する多数の突起が成形されたコア材としてのキャップシートと、突起内に空気を封入して気泡を形成する一方の外装材としてのバックシートと、突起の頂面側に積層された他方の外装材としてのライナーシートとを備えた気泡ボードなどを好適に用いることができる。
厚板材１の厚みは、５〜１０００ｍｍ程度が好ましく、より好ましくは、１０〜５００ｍｍである。
The thick plate material 1 is made of a foam board formed using a resin such as polypropylene, for example, a cap sheet as a core material formed with a large number of protrusions that protrude in a hollow shape, and air is sealed in the protrusions to form air bubbles. It is possible to suitably use a bubble board or the like provided with a back sheet as one exterior material forming the above, and a liner sheet as the other exterior material laminated on the top surface side of the projection.
The thickness of the thick plate 1 is preferably about 5 to 1000 mm, more preferably 10 to 500 mm.
高剛性部１１は、折り線ＦＬの一方側に配置され、曲げ剛性が高い部分である。この高剛性部１１は、図２（ａ）に示すように、折り線ＦＬに直交する断面形状が折り線ＦＬ側に突出する凸状部（図中、高剛性部１１と重なって図示される一点鎖線より上側の部分）１１ａを備えている。 The high-rigidity portion 11 is arranged on one side of the fold line FL and has high bending rigidity. As shown in FIG. 2A, the high-rigidity portion 11 has a convex portion whose cross-sectional shape orthogonal to the fold line FL protrudes toward the fold line FL (in the drawing, the high-rigidity portion 11 overlaps the high-rigidity portion 11). (A portion above the one-dot chain line) 11a.
低剛性部１２は、折り線ＦＬの他方側に配置され、高剛性部１１よりも曲げ剛性が低い部分である。この低剛性部１２は、図２（ａ）に示すように、少なくとも高剛性部１１の凸状部１１ａを収容できる凹状部（図中、低剛性部１２側に図示される一点鎖線より下側の部分）１２ａを備えている。 The low rigidity portion 12 is a portion that is arranged on the other side of the folding line FL and has lower bending rigidity than the high rigidity portion 11. As shown in FIG. 2A, the low-rigidity portion 12 has a concave portion (at a lower side than the one-dot chain line shown on the low-rigidity portion 12 side in the figure) that can accommodate at least the convex portion 11a of the high-rigidity portion 11. ) 12a.
折曲案内線１３は、高剛性部１１と低剛性部１２の境界線に沿って、低剛性部１２が折り曲がることにより、折り曲げの案内になる線である。図２（ａ）の白抜きの矢印のように折り曲げて、折り曲げ加工をするときに、剛性の低い低剛性部１２が、高剛性部１１との境界である折曲案内線１３から折り曲がることにより、きれいに折り曲げることができる。
その結果、折り曲げ加工時に、折れ線にあそびができて、折り線の位置が定まり難いという問題を解消でき、折り線が設計通りの位置で折れないために、機構の頑健性が低くなるなどの問題が生じたりすることもない。
The bending guide line 13 is a line that guides the bending when the low-rigidity portion 12 is bent along the boundary between the high-rigidity portion 11 and the low-rigidity portion 12. When bending and bending as shown by the outline arrows in FIG. 2A, the low-rigidity portion 12 having low rigidity is bent from the bending guide line 13 which is a boundary with the high-rigidity portion 11. Thereby, it can be folded neatly.
As a result, it is possible to solve the problem that the folding line can play at the bending line and it is difficult to determine the position of the folding line, and the fold line can not be broken at the designed position, resulting in poor robustness of the mechanism. Does not occur.
（テーパ部のプロポーション）
本実施形態のような高剛性部１１及び低剛性部１２がない場合には、厚板材１は、図２（ｂ）に示すように、テーパ部２を形成するときに、厚板材１の展開状態に直交する平面に対称な断面形状により、厚みＴをコントロールすることになる。
具体的には、折り角（展開状態において０、谷折りで正、山折りで負になるようにとる。）の限界値をρとおくと、底面３から測ったテーパ部２の角度（テーパ角）θは、
θ＝（π−ρ）／２ ・・・（１）
となり、厚みＴの厚板材１であれば、テーパ部２の幅ｗは、
ｗ＝Ｔ×ｔａｎ（ρ／２） ・・・（２）
となる。
(Proportion of the tapered part)
In the case where there is no high-rigidity portion 11 and low-rigidity portion 12 as in the present embodiment, as shown in FIG. 2B, when the tapered portion 2 is formed, the thick plate 1 is developed. The thickness T is controlled by a cross-sectional shape symmetrical to a plane orthogonal to the state.
Specifically, if the limit value of the folding angle (taken to be 0 in the unfolded state, positive in the valley fold, and negative in the mountain fold) is ρ, the angle of the tapered portion 2 measured from the bottom surface 3 (taper Angle) θ is
θ = (π−ρ) / 2 (1)
In the case of a thick plate material 1 having a thickness T, the width w of the tapered portion 2 is
w = T × tan (ρ / 2) (2)
Becomes
本実施形態では、折り角ρを１３５°としてあるので、テーパ角θは、
θ＝（１８０°−１３５°）／２＝２２．５°
であり、厚みＴに対して、２．４（≒ｔａｎ（１３５／２））倍程度の細長いプロポーションのテーパ部２でヒンジ構造を支えることになる。
In the present embodiment, since the folding angle ρ is set to 135 °, the taper angle θ is
θ = (180 ° −135 °) /2=22.5°
The hinge structure is supported by the tapered portion 2 having an elongated proportion of about 2.4 (≒ tan (135/2)) times the thickness T.
（曲げ剛性の向上）
本実施形態によれば、高剛性部１１を設けているので、左右対称の場合（図２（ｂ）の場合）に比較して、２倍以上の曲げ剛性が容易に達成される。
例えば、図２（ａ）に示すように、テーパ部２を０°と４５°のテーパに分割した場合には、低剛性部１２の剛性は０である一方で、剛性は厚みの３乗に比例することから、高剛性部１１の先端部の剛性は、２２．５°づつとした場合（図２（ｂ）の場合）の１４（≒（ｔａｎ４５）３／（ｔａｎ２２．５）３）倍程度となり、低剛性部１２と高剛性部１１との平均で、７（＝（０＋１４）／２）倍程度の曲げ剛性をもつことが期待でき、曲げ剛性は向上することがわかる。
(Improvement of bending rigidity)
According to the present embodiment, since the high-rigidity portion 11 is provided, a bending rigidity of twice or more can be easily achieved as compared with the case of the left-right symmetry (the case of FIG. 2B).
For example, as shown in FIG. 2A, when the tapered portion 2 is divided into 0 ° and 45 ° tapers, the rigidity of the low rigidity portion 12 is 0, but the rigidity is a cube of the thickness. Since it is proportional, the rigidity of the tip end of the high-rigidity portion 11 is 14 (≒ (tan45) 3 /(tan22.5) 3 ) times when the angle is 22.5 ° (in the case of FIG. 2B). The bending rigidity can be expected to be about 7 (= (0 + 14) / 2) times the average of the low rigidity part 12 and the high rigidity part 11, and the bending rigidity is improved.
また、本実施形態に係る折り線ヒンジ構造１０は、折り線ＦＬに対して、高剛性部１１と低剛性部１２を配置して、非対称な断面形状とすることにより、高剛性部１１と低剛性部１２の境界線にある折曲予定線１３に沿って、曲げ剛性の低い低剛性部１２が折り曲がるようにした。
このため、曲げ加工時に、折り線ＦＬに対して左右対称な断面形状である場合に、折り位置が定まらなかったというようなことはなくなり、折曲予定線１３に沿って、正確かつ容易の折り曲げることができるようになった。
In addition, the folding line hinge structure 10 according to the present embodiment arranges the high-rigidity portion 11 and the low-rigidity portion 12 with respect to the folding line FL to have an asymmetrical cross-sectional shape, so that the high-rigidity portion 11 and the low-rigidity portion 11 are low. The low-rigidity portion 12 having low bending rigidity is bent along the predetermined bending line 13 at the boundary of the rigidity portion 12.
For this reason, when the cross-sectional shape is symmetrical with respect to the folding line FL at the time of bending, it does not happen that the folding position is not determined, and accurate and easy bending is performed along the planned bending line 13. Now you can do it.
また、第１実施形態に係る折り線ヒンジ構造１０は、図１に示すように、高剛性部１１及び低剛性部１２は、折り線ＦＬに沿って複数組（１０−１、１０−２、１０−３、１０−４、・・・）形成されており、隣接する組ごとに（例えば、ヒンジ構造１０−２とヒンジ構造１０−３）、高剛性部１１及び低剛性部１２の配置が逆になっている。
この折り線ヒンジ構造１０は、高剛性部１１を作ることにより、反対側の低剛性部１２の曲げ剛性が減ることになる。このため、本実施形態では、折り線ＦＬに沿って、高剛性部１１の反転を、繰り返すことにより、折り線ＦＬ全体で平均して面外剛性を保てるようにしてある。
Further, in the folding line hinge structure 10 according to the first embodiment, as shown in FIG. 1, the high rigidity portion 11 and the low rigidity portion 12 include a plurality of sets (10-1, 10-2, 10-3, 10-4,...), And the arrangement of the high-rigidity portion 11 and the low-rigidity portion 12 is set for each adjacent pair (for example, the hinge structure 10-2 and the hinge structure 10-3). It is upside down.
In the folding line hinge structure 10, by forming the high rigidity portion 11, the bending rigidity of the opposite low rigidity portion 12 is reduced. For this reason, in the present embodiment, the inversion of the high-rigidity portion 11 is repeated along the folding line FL, so that the out-of-plane rigidity can be maintained on average over the entire folding line FL.
また、高剛性部１１と低剛性部１２を互い違いに配置し、最大折り角ρまで折り曲げたときに、厚板材１の折り線ヒンジ構造１０が互いに嵌合するように構成すれば、最大折り角ρまで折り曲げた状態を維持することも可能となり、施工性の向上が期待できる。 Further, if the high-rigidity portions 11 and the low-rigidity portions 12 are arranged alternately and are bent to the maximum folding angle ρ, the folding line hinge structures 10 of the thick plate 1 are fitted to each other, so that the maximum folding angle is obtained. It is also possible to maintain the state of being bent to ρ, and improvement in workability can be expected.
（加熱・加圧部）
図３は、本実施形態に係る折り線ヒンジ構造の製造に使用する加熱・加圧部を説明する斜視図である。
加熱・加圧部５０は、図１の折り線ヒンジ構造１０を熱成形するための焼き鏝であり、折り線ヒンジ構造１０を構成する凹凸部の逆型になっている。
つまり、加熱・加圧部５０は、折り線ヒンジ構造１０の高剛性部１１を成形する凹型部５１と、低剛性部１２を成形する凸型部５２とが、交互に配置されている（凸型部５２−１、凹型部５１−１と、凹型部５１−２、凸型部５２−２とが交互になっている）。
(Heating / pressing part)
FIG. 3 is a perspective view illustrating a heating / pressing unit used for manufacturing the folding line hinge structure according to the present embodiment.
The heating / pressing unit 50 is a trowel for thermoforming the folding line hinge structure 10 of FIG. 1, and is an inverse of the concave and convex portions forming the folding line hinge structure 10.
That is, in the heating / pressing unit 50, the concave portions 51 for forming the high rigidity portion 11 of the folding line hinge structure 10 and the convex portions 52 for forming the low rigidity portion 12 are alternately arranged (convex). The mold part 52-1, the concave part 51-1 and the concave part 51-2, the convex part 52-2 are alternately arranged).
［第２実施形態］
図４は、本発明による折り線ヒンジ構造の第２実施形態を示す斜視図である。
なお、以下に説明する第２、第３、第４実施形態では、第１実施形態と同様な機能を果たす部分には、末尾に共通する符号を付して、重複する説明を適宜省略する。
第２実施形態に係る折り線ヒンジ構造２０は、図４に示すように、高剛性部２１と、低剛性部２２と、折曲案内線２３とを備えている。
この折り線ヒンジ構造２０は、互い違いにする高剛性部２１と低剛性部２２のピッチｐが第１実施形態よりも狭くなっている。
第２実施形態によれば、互い違いにする高剛性部２１と低剛性部２２のピッチｐを狭くすることで、折り線ヒンジ構造１０が互いに嵌合する面積が増えるため、最大折り角ρまで折り曲げたときに、より容易に、その状態を維持できるようにすることが可能になる。
[Second embodiment]
FIG. 4 is a perspective view showing a second embodiment of the folding line hinge structure according to the present invention.
In the second, third, and fourth embodiments described below, parts that perform the same functions as in the first embodiment are denoted by the same reference numerals at the end, and redundant description will be omitted as appropriate.
As shown in FIG. 4, the folding line hinge structure 20 according to the second embodiment includes a high rigidity portion 21, a low rigidity portion 22, and a bending guide line 23.
In the fold line hinge structure 20, the pitch p between the high rigidity portions 21 and the low rigidity portions 22 that are alternately arranged is narrower than in the first embodiment.
According to the second embodiment, the narrower pitch p between the high-rigidity portions 21 and the low-rigidity portions 22 that are alternately provided increases the area where the folding line hinge structures 10 fit each other. , It becomes possible to maintain the state more easily.
［第３実施形態］
図５は、本発明による折り線ヒンジ構造の第３実施形態に係る折り線ヒンジ構造を説明する説明図であり、折り線ＦＬに直交する断面形状を示している。
また、図５は、折り角ρを９０°とした場合の例を示しており、参考として、対称な断面形状による例を図５（ｃ）に示している。
本実施形態では、図５（ａ）に示すように、凸状部２１ａ及び凹状部２２ａの断面外形形状は、折れ線形状としてある。
このような本実施形態によれば、折曲予定線２３の部分を十分に曲げ剛性を低くして、折り曲げやすくしても、この凹状部２２ａの断面形状により、徐々に肉厚を厚くすることができ、低剛性部２２の曲げ剛性を上げることができる。
第３実施形態によれば、第１実施形態の効果に加えて、第１実施形態では低剛性部２２側に厚みゼロの領域があるのに対して、この形態では、若干のテーパが低剛性部２２側に残り、厚みがゼロとならない部分があるので、加工時に端材が出ないことや、気密性の保持が期待できる。
[Third embodiment]
FIG. 5 is an explanatory view for explaining a fold line hinge structure according to a third embodiment of the fold line hinge structure according to the present invention, and shows a cross-sectional shape orthogonal to the fold line FL.
FIG. 5 shows an example in which the folding angle ρ is 90 °, and FIG. 5C shows an example of a symmetrical cross-sectional shape for reference.
In the present embodiment, as shown in FIG. 5A, the cross-sectional external shape of the convex portion 21a and the concave portion 22a is a polygonal line shape.
According to the present embodiment, even if the bending portion 23 has a sufficiently low bending rigidity so that it can be easily bent, the thickness is gradually increased by the cross-sectional shape of the concave portion 22a. Thus, the bending rigidity of the low rigidity portion 22 can be increased.
According to the third embodiment, in addition to the effect of the first embodiment, in the first embodiment, there is a region of zero thickness on the low-rigidity portion 22 side. Since there is a portion remaining on the side of the portion 22 and the thickness does not become zero, it is possible to expect that no scrap is produced during processing and that airtightness is maintained.
（変形例）
本実施形態では、図５（ｂ）に示すように、凸状部２１ａ−１及び凹状部２２ａ−１の断面外形形状が、曲線（円弧）形状とされた、折り線ヒンジ構造２０−１としてもよい。
このような変形例によれば、前記効果に加えて、折曲予定線２３−１で折り曲げ工程が進むにつれて、徐々に連続的に対向面が重なるようになるので、安定して折曲加工をすることができる。
この例では、テーパの先端部分のシャープさをとることにより、応力集中を避けることができ、また、熱罫線や型抜きをするときの加工がしやすいという効果がある。
(Modification)
In the present embodiment, as shown in FIG. 5B, a folded line hinge structure 20-1 in which the cross-sectional outer shape of the convex portion 21a-1 and the concave portion 22a-1 is a curved (arc) shape. Is also good.
According to such a modified example, in addition to the above-described effects, as the bending process proceeds at the planned bending line 23-1, the facing surfaces gradually and continuously overlap, so that the bending process can be stably performed. can do.
In this example, there is an effect that stress concentration can be avoided by taking sharpness of the tip portion of the taper, and processing at the time of hot crease or die cutting is facilitated.
