【発明の属する技術分野】
本発明は、例えば屋内外での集会や催物や行事等に用いられる折畳み式テントフレームの改良に関する。
【０００２】
【従来の技術】
従来、テントフレームとしては、支柱を折畳み式にして保管時の全高を低くするもの（特許文献１、特許文献２）や、屋根構造に索条と頂点支柱を用いて軽量化を図ったもの（特許文献３参照）が知られている。

【発明が解決しようとする課題】
ところが、何れのものも、一長一短があり、保管時の全高を低くすると共に、屋根構造の軽量化を図るものがなかった。又、後者のものは、各索条毎に張力調節器を設けていたので、張力調節に手間が掛かると共に、コストが高く付く難点があった。
【０００５】
本発明は、叙上の問題点に鑑み、これを解消する為に創案されたもので、その課題とする処は、保管時の全高を低くすると共に、屋根構造の軽量化を図り、然も、張力調節に掛かる手間とコストを削減できる様にした折畳み式テントフレームを提供するにある。
【０００６】
【課題を解決するための手段】
本発明の折畳み式テントフレームは、基本的には、平面方形を呈すべく配された縦横の梁材と、隣接する梁材同士を連結する継手と、各継手に設けられて梁材に折重なる折畳み位置から直立位置まで折畳み可能な支柱と、対角線上に位置する継手間に着脱可能に架設される二つの索条と、一方の索条のみに設けられて張力を調節する張力調節器と、から構成した事に特徴が存する。
【０００７】
各支柱を折畳み位置にすると、折畳み式テントフレームの全高が低くなる。従って、これの保管や運搬が容易になる。
各支柱を直立位置にすると、折畳み式テントフレームが立ち上がり、使用可能になる。
張力調節器に依り一方の索条を緊張させると、四つの梁材に依り形成される方形の一方の対角線間が短縮される。そうすると、前記方形が極端に言えば菱形に変形される事になり、他方の対角線間が伸長されてこの間にある索条が自動的に緊張される。従って、張力調節器は、一方の索条のみに設けて置けば良く、各索条に設ける必要がない。
【０００８】
両索条の交差部には、頂点支柱が着脱可能に立設されているのが好ましい。この様にすれば、中心を高くした所謂角錐型の屋根構造にする事ができる。
【０００９】
継手は、縦梁材が嵌合される縦筒体と、横梁材が嵌合される横筒体と、支柱が嵌合される垂直筒体と、索条の端部を係止する係止部とを備え、垂直筒体と支柱との間には、支柱が嵌合される嵌合位置とこれから下方に引き抜かれて折畳み可能な引き抜き位置とをとり得る枢軸手段が設けられているのが好ましい。この様にすれば、支柱の直立位置の時には、支柱が継手の垂直筒体に嵌合されるので、強度が増大する。
【００１０】
継手は、縦筒体と横筒体を備えた上継手と、垂直筒体を備えた下継手とに二分割されていると共に、これらの間には下継手に対して上継手を横軸廻りに回動可能にする角度調節手段が設けられているのが好ましい。この様にすれば、支柱に対して縦梁材を傾斜させる事ができ、所謂片流れ型の屋根構造にする事ができる。
【００１１】
【発明の実施の形態】
以下、本発明の実施の形態を、図面に基づいて説明する。
図１は、本発明の第一例に係る折畳みテントフレームを示す正面図。図２は、図１の平面図。図３は、折畳み状態を示す正面図。図４は、要部を拡大して示す正面図。図５は、要部を拡大して示す側面図。図６は、要部を拡大して示す平面図。図７は、図６の縦断面図である。
【００１２】
折畳み式テントフレーム１は、梁材２、継手３、支柱４、索条５、張力調節器６とからその主要部が構成されている。
【００１３】
梁材２は、平面方形を呈すべく配された縦横のもので、この例では、左右の縦梁材７と前後の横梁材８とを備えて居り、同じ長さのアルミ製の角パイプが用いられてこれらが平面正方形を呈すべく配されている。
而して、各梁材２の下面には、これらと略同じ長さのカーテンレール９が付設されて居り、これには、図略しているが、カーテンが吊下げられる。
【００１４】
継手３は、隣接する梁材２同士を連結するもので、この例では、縦梁材７が嵌合される角筒状の縦筒体１０と、横梁材８が嵌合される同じく角筒状の横筒体１１と、支柱４が嵌合される同じく角筒状の垂直筒体１２と、縦筒体１０と横筒体１１との間に跨って設けられた水平リブ１３と、これと垂直筒体１２との間に跨って設けられた垂直リブ１４と、水平リブ１３の上に設けられて索条５の端部を係止する係止部（フック）１５と、縦筒体１０と横筒体１１の外角部に設けられて補強用ロープ等（図示せず）が止結される穴付ブラケット１６とを備え、アルミダイキャストに依り作製されている。
縦筒体１０と横筒体１１には、縦梁材７と横梁材８を固定する為の固定具（蝶ボルト）１７が設けられている。垂直筒体１２と支柱４との間には、支柱４が嵌合される嵌合位置とこれから下方に引き抜かれて折畳み可能な引き抜き位置とをとり得る枢軸手段１８が設けられていると共に、支柱４を垂直位置に固定する為の固定具（ボルトと蝶ナット）１９が設けられている。
【００１５】
枢軸手段１８は、継手３の垂直筒体１２に設けられた高さ方向に長い長穴２０と、支柱４に穿設された貫孔２１と、これらに挿通されて継手３の垂直筒体１２と支柱４とを枢結する枢結具（ボルトと袋ナット）２２と、継手３の垂直筒体１２に設けられて折畳み位置の支柱４との干渉を回避する切欠２３とを備え、継手３に対して支柱４を縦（前後方向）軸廻りに回動できる様にしてある。
【００１６】
支柱４は、各継手３に設けられて梁材２に折重なる折畳み位置から垂直位置まで折畳み可能なもので、この例では、梁材２と同様のアルミ製の角パイプが用いられて居り、横梁材８及び他方の支柱４に折重なる折畳み位置から垂直位置まで折畳み可能にしてあり、下部には、地面等に接地される座体２４が固定具（ボルトと蝶ナット）２５に依り着脱可能に設けられている。
【００１７】
索条５は、対角線上に位置する継手３間に着脱可能に設けられた二つのもので、この例では、ワイヤロープが用いられて居り、両端には、継手３の係止部１５に係止可能な環状部２６が結束具２７に依り形成されている。
【００１８】
張力調節器６は、一方の索条５のみに設けられて張力を調節するもので、この例では、ターンバックルが用いられて居り、一方の索条５の環状部２６に連結される小リング２８と、継手の係止部１５に係止される大リンク２９とを備えている。中央のナット部分を回動させる事に依り長さを調整できる様になっている。
【００１９】
両索条５の交差部には、頂点支柱３０が固定具３１に依り着脱可能に立設されている。
頂点支柱３０は、幕体Ａを角錐状に張る為のもので、アルミ製の丸パイプが用いられて居り、下部には、索条５の交差部が挿入される平面十字状の切溝３２が形成されている。固定具３１は、平面略Ｕ型を呈する締付環とこれの両端部に設けられたボルト・ナットとを備えている。
【００２０】
次に、この様な構成に基づいてその作用を述解する。
図３の実線は、折畳み式テントフレーム１の折畳み状態を示している。この場合、支柱４から座体２４が外され、左右のうちの一方（右側）の支柱４が横梁材８の下に折重なる様に折畳まれていると共に、他方（左側）の支柱４が一方（右側）の支柱４の下に折重なる様に折畳まれている。
折畳み状態では、図１に示す直立状態の時に比べて全高が極めて低くなって居り、運搬や保管が容易になる。
【００２１】
折畳み状態から、図３の鎖線で示す如く、頂点支柱３０が両索条５の交差部に立設されると共に、この上から幕体Ａが覆い被せられる。
そして、左右の支柱４が枢軸手段１８に依り引き抜き位置まで回動されると共に、嵌合位置まで持ち上げられて支柱４の上部が継手３の垂直筒体１２に嵌合された後、固定具１９に依り支柱４と継手３が結合される。
支柱４の下部には、座体２４が固定具２５に依り取付けられると共に、カーテンレール９には、図略しているが、カーテンが吊下げられる。そうすると、図１の様な直立状態となり、例えば更衣室代わりのテントとして使用できる。
【００２２】
張力調節器６に依り一方の索条５を緊張させると、四つの梁材２に依り形成される方形の一方の対角線間が短縮される。そうすると、前記方形が極端に言えば菱形に変形される事になり、他方の対角線間が伸長されてこの間にある他方の索条５が自動的に緊張される。
従って、張力調節器６は、一方の索条５のみに設けて置けば良く、各索条５に設ける必要がない。
勿論、両索条５の長さを予め設定して置き、張力調節器６に依り緊張させた後の四つの梁材２に依り形成される形状が、適正な方形になる様にして置く方が望ましい。
【００２３】
折畳み状態では、頂点支柱３０と幕体Ａを付けたままにして置いても良い。この場合には、支柱４を直立させるだけで、使用する事ができるので、一時的に保管する場合には、最適である。
折畳み式テントフレーム１は、梁材２、継手３、支柱4、一方の索条５、張力調節器を備えた他方の索条５、座体２４、頂点支柱３０等に分解できるので、これら部品としての運搬や保管も容易である。
【００２４】
次に、本発明の第二例を、図８乃至図１０に基づいて説明する。
図８は、本発明の第二例の折畳み式テントフレームを示す側面図。図９は、要部を拡大して示す正面図。図１０は、要部を拡大して示す側面図である。
【００２５】
第二例は、継手３を、縦筒体１０と横筒体１１を備えた上継手３３と、垂直筒体１２を備えた下継手３４とに二分割した点、これらの間には下継手３４に対して上継手３３を横軸廻りに回動可能にする角度調節手段３５を設けた点、支柱４を伸縮可能にした点、が第一例と異なり、その他は、第一例と同様である。
【００２６】
角度調節手段３５は、上継手３３と下継手３４とを枢結する枢結具（ボルトとナット）３６と、上継手３３と下継手３４との間に形成されて下継手３４に対して上継手３３を所定角度（５度）毎に係合させる歯部３７とを備えている。
支柱４は、上下に二分割されて居り、継手３の垂直筒体１２に嵌合される上支柱３８と、これの内部に摺動可能に挿入されて下部には座体が取付けられる下支柱３９とを備えている。上支柱３８と下支柱３９との間には、高さ調節手段４０が設けられている。
【００２７】
高さ調節手段４０は、上支柱３８の下部に穿設された貫孔４１と、下支柱３９の上半に一定間隔毎に穿設された複数の透孔４２と、貫孔４１と透孔４２の一つに挿通されて上支柱３８と下支柱３９を結合する結合具（ボルトと蝶ナット）４３とを備えている。
【００２８】
この様なものは、角度調節手段３５を備えているので、支柱４に対して、前側の継手３を鋭角度（８０度）にすると共に、後側の継手３を鈍角度（１００度）にする事に依り左右の縦梁材７を前側が高い所定の傾斜角度（１０度）を備えた傾斜状態にする事ができる。この場合には、頂点支柱３０が不要であり、索条５と幕体Ａとから成る屋根構造を、所謂片流れ型にする事ができる。
加えて、この場合には、高さ調節手段４０を備えているので、前側の支柱４を高くして後側の支柱４を低くする事ができる。
【００２９】
尚、梁材２は、先の例では、平面正方形であったが、これに限らず、例えば平面長方形であっても良い。
支柱４は、先の例では、縦（前後方向）軸廻りに折畳まれる様にしたが、これに限らず、例えば横（左右方向）軸廻りに折畳まれる様にしても良い。
索条５は、先の例では、ワイヤロープであったが、これに限らず、例えばチェーン等であっても良い。
張力調節器６は、先の例では、索条５の端部に設けたが、これに限らず、例えば索条５の中間部に設けても良い。
枢軸手段１８は、第二例では、設けていたが、これに限らず、例えばこれを割愛しても良い。この場合、支柱４の折畳みは、角度調節手段３５に依って兼用させる事ができる。
高さ調節手段４０は、第二例では、設けていたが、これに限らず、例えばこれを割愛しても良い。この場合、前後の支柱４は、縦梁材７の傾斜角度に見合った長さにする必要がある。
【００３０】
【発明の効果】
以上、既述した如く、本発明に依れば、次の様な優れた効果を奏する事ができる。
（１）底平面方形を呈すべく配された縦横の梁材と、隣接する梁材同士を連結する継手と、各継手に設けられて梁材に折重なる折畳み位置から直立位置まで折畳み可能な支柱と、対角線上に位置する継手間に着脱可能に架設される二つの索条と、一方の索条のみに設けられて張力を調節する張力調節器とで構成し、支柱を折畳み可能にすると共に、屋根構造に索条と張力調節器を用いたので、保管時の全高を低くする事ができると共に、屋根構造の軽量化を図る事ができる。
（２）張力調節器を単一にしたので、張力調節に掛かる手間とコストを削減できる。

BACKGROUND OF THE INVENTION
The present invention relates to an improvement in a folding tent frame used for, for example, indoor and outdoor gatherings, events, and events.
[0002]
[Prior art]
Conventionally, as a tent frame, a column is foldable to reduce the total height during storage (Patent Document 1, Patent Document 2), and a roof structure using a rope and apex column to reduce weight ( Patent Document 3) is known.
[0003]
[Patent Document 1]
JP 2001-303800 A [Patent Document 2]
JP 2002-138713 A [Patent Document 3]
Japanese Patent Laid-Open No. 2002-81227
[Problems to be solved by the invention]
However, each of them has advantages and disadvantages, and there has been nothing to reduce the overall height during storage and reduce the weight of the roof structure. In the latter case, since a tension adjuster is provided for each rope, it takes time to adjust the tension, and the cost is high.
[0005]
The present invention was devised in view of the problems described above, and was devised to solve this problem, and the problem is that the overall height during storage is reduced and the roof structure is lightened. The purpose of the present invention is to provide a folding tent frame that can reduce the labor and cost required for tension adjustment.
[0006]
[Means for Solving the Problems]
The foldable tent frame of the present invention basically has vertical and horizontal beam members arranged so as to have a flat rectangular shape, joints that connect adjacent beam members, and is provided at each joint and overlaps the beam members. A strut that can be folded from a folding position to an upright position, two ropes that are detachably mounted between joints located on a diagonal line, and a tension adjuster that is provided only on one of the ropes to adjust the tension; There is a feature in that it consists of.
[0007]
When each column is in the folding position, the overall height of the folding tent frame is lowered. Therefore, it is easy to store and transport it.
When each column is in an upright position, the folding tent frame is raised and ready for use.
When one of the ropes is tensioned by the tension adjuster, the distance between the diagonal lines of the square formed by the four beam members is shortened. If it does so, the said square will deform | transform into a rhombus if it says extremely, the other diagonal will be extended, and the cord in between will be tensioned automatically. Accordingly, the tension adjuster may be provided only on one of the ropes, and does not need to be provided on each rope.
[0008]
It is preferable that apex struts are erected so as to be detachable at the intersections of the two ropes. In this way, a so-called pyramidal roof structure with a raised center can be obtained.
[0009]
The joint includes a vertical cylinder body to which the vertical beam member is fitted, a horizontal cylinder body to which the horizontal beam material is fitted, a vertical cylinder body to which the support column is fitted, and a latch that locks the end of the rope. A pivot means is provided between the vertical cylindrical body and the support column, which can take a fitting position where the support column is fitted and a pull-out position that can be pulled down and folded. preferable. In this way, when the support column is in the upright position, the support column is fitted to the vertical cylinder of the joint, so that the strength is increased.
[0010]
The joint is divided into two parts, an upper joint having a vertical cylinder and a horizontal cylinder, and a lower joint having a vertical cylinder. Between these, the upper joint is rotated around the horizontal axis with respect to the lower joint. It is preferable that an angle adjusting means for enabling rotation is provided. In this way, the vertical beam member can be inclined with respect to the support column, and a so-called single-flow roof structure can be obtained.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a front view showing a folding tent frame according to a first example of the present invention. FIG. 2 is a plan view of FIG. FIG. 3 is a front view showing a folded state. FIG. 4 is an enlarged front view showing a main part. FIG. 5 is an enlarged side view showing a main part. FIG. 6 is an enlarged plan view showing a main part.

In this example, the beam member 2 includes left and right longitudinal beam members 7 and front and rear transverse beam members 8, and an aluminum square pipe having the same length is provided. Used to be arranged to present a planar square.
Thus, a curtain rail 9 having substantially the same length as these is attached to the lower surface of each beam member 2, and although not shown, the curtain is suspended.
[0014]
The joint 3 connects adjacent beam members 2 to each other, and in this example, a rectangular tube-like vertical cylinder body 10 into which the vertical beam member 7 is fitted and a rectangular tube in which the horizontal beam member 8 is fitted. Horizontal tubular body 11, a rectangular tube-like vertical tubular body 12 into which the support column 4 is fitted, a horizontal rib 13 provided between the vertical tubular body 10 and the horizontal tubular body 11, and Vertical ribs 14 provided between the vertical cylinders 12 and the vertical cylinders 12, locking portions (hooks) 15 provided on the horizontal ribs 13 to lock the ends of the ropes 5, and vertical cylinders 10 and a bracket 16 with a hole provided at an outer corner of the horizontal cylindrical body 11 to which a reinforcing rope or the like (not shown) is fastened, and is manufactured by aluminum die casting.
The vertical cylinder body 10 and the horizontal cylinder body 11 are provided with a fixture (wing bolt) 17 for fixing the vertical beam member 7 and the horizontal beam member 8. Between the vertical cylinder 12 and the support column 4, there is provided a pivot means 18 that can take a fitting position where the support column 4 is fitted and a drawing position where it can be pulled down and folded down. Fixing tools (bolts and wing nuts) 19 for fixing 4 in a vertical position are provided.
[0015]
The pivot means 18 is a long hole 20 provided in the vertical cylinder 12 of the joint 3 in the height direction, a through hole 21 drilled in the support column 4, and the vertical cylinder 12 of the joint 3 inserted through these. And a pivoting tool (bolt and cap nut) 22 for pivotally coupling the column 4 and a notch 23 provided on the vertical cylindrical body 12 of the coupling 3 to avoid interference with the column 4 at the folding position. In contrast, the support column 4 can be rotated around a vertical (front-rear direction) axis.
[0016]
The support column 4 is provided on each joint 3 and can be folded from the folding position where the beam material 2 is folded to the vertical position. In this example, an aluminum square pipe similar to the beam material 2 is used, It is possible to fold from the folding position that overlaps the cross beam 8 and the other support column 4 to the vertical position, and at the bottom, a seat body 24 that is grounded to the ground or the like can be attached and detached by a fixture (bolt and wing nut) 25 Is provided.
[0017]
The rope 5 is detachably provided between the joints 3 positioned on the diagonal line. In this example, a wire rope is used, and the both ends are engaged with the locking portions 15 of the joint 3. An annular portion 26 that can be stopped is formed by a binding device 27.
[0018]
The tension adjuster 6 is provided only on one rope 5 and adjusts the tension. In this example, a turnbuckle is used and a small ring connected to the annular portion 26 of the one rope 5 is used. 28 and a large link 29 locked to the locking portion 15 of the joint. The length can be adjusted by rotating the central nut.
[0019]
An apex column 30 is erected at the intersection of the two ropes 5 so as to be detachable by a fixing tool 31.
The apex column 30 is used to stretch the curtain body A into a pyramid shape, and an aluminum round pipe is used, and a flat cross-shaped cut groove 32 into which an intersection of the rope 5 is inserted at the lower part. Is formed. The fixture 31 includes a tightening ring having a substantially U-shaped plane and bolts and nuts provided at both ends thereof.
[0020]
Next, the operation will be described based on such a configuration.
A solid line in FIG. 3 shows a folded state of the folding tent frame 1. In this case, the seat body 24 is removed from the support column 4, and one of the left and right (right side) support columns 4 is folded under the cross beam member 8, and the other (left side) support column 4 is folded. It is folded so as to fold under one (right side) column 4.
In the folded state, the overall height is extremely lower than that in the upright state shown in FIG. 1, and transportation and storage are facilitated.
[0021]
From the folded state, as shown by the chain line in FIG. 3, the apex column 30 is erected at the intersection of the two ropes 5, and the curtain body A is covered from above.
Then, the left and right support columns 4 are rotated to the pulling position by the pivot means 18 and lifted to the fitting position so that the upper portion of the support column 4 is fitted to the vertical cylinder 12 of the joint 3, and then the fixture 19. Therefore, the support column 4 and the joint 3 are coupled.
A seat body 24 is attached to the lower portion of the support column 4 by a fixing tool 25, and a curtain is suspended from the curtain rail 9 (not shown). If it does so, it will be in an upright state like FIG. 1, and can be used, for example as a tent instead of a changing room.
[0022]
When one of the ropes 5 is tensioned by the tension adjuster 6, the distance between the diagonal lines of the square formed by the four beam members 2 is shortened. If it does so, the said square will deform | transform into a rhombus if it says extremely, the other diagonal will be extended, and the other rope 5 in the meantime will be tensioned automatically.
Therefore, the tension adjuster 6 may be provided only on one of the ropes 5, and need not be provided on each of the ropes 5.
Of course, the length of the two ropes 5 is set in advance and placed so that the shape formed by the four beam members 2 after being tensioned by the tension adjuster 6 becomes an appropriate square. Is desirable.
[0023]
In the folded state, the apex column 30 and the curtain A may be left attached. In this case, the column 4 can be used simply by standing upright, and is optimal for temporary storage.
The foldable tent frame 1 can be disassembled into a beam member 2, a joint 3, a support column 4, one cable strip 5, the other cable 5 with a tension adjuster, a seat body 24, an apex column 30 and the like. It can be easily transported and stored.
[0024]
Next, a second example of the present invention will be described with reference to FIGS.
FIG. 8 is a side view showing a folding tent frame according to a second example of the present invention. FIG. 9 is an enlarged front view showing a main part. FIG. 10 is an enlarged side view showing a main part.

In the second example, the joint 3 is divided into two parts, an upper joint 33 provided with the vertical cylinder body 10 and the horizontal cylinder body 11 and a lower joint 34 provided with the vertical cylinder body 12. Unlike the first example, the angle adjustment means 35 that allows the upper joint 33 to rotate about the horizontal axis with respect to 34 and the support 4 can be extended and contracted are the same as the first example. It is.
[0026]
The angle adjusting means 35 is formed between a joint (bolt and nut) 36 that pivotally connects the upper joint 33 and the lower joint 34, and the upper joint 33 and the lower joint 34, and is located above the lower joint 34. And a tooth portion 37 that engages the joint 33 every predetermined angle (5 degrees).
The support column 4 is divided into two parts, the upper support column 38 fitted into the vertical cylinder 12 of the joint 3, and the lower support column that is slidably inserted into the lower support column and a seat is attached to the lower part. 39. A height adjusting means 40 is provided between the upper column 38 and the lower column 39.

Since such an apparatus is provided with the angle adjusting means 35, the front joint 3 is set to an acute angle (80 degrees) with respect to the column 4, and the rear joint 3 is set to an obtuse angle (100 degrees). By doing so, the left and right vertical beam members 7 can be inclined with a predetermined inclination angle (10 degrees) high on the front side. In this case, the apex column 30 is unnecessary, and the roof structure composed of the rope 5 and the curtain A can be a so-called single-flow type.
In addition, in this case, since the height adjusting means 40 is provided, the front column 4 can be raised and the rear column 4 can be lowered.

In the above example, the beam member 2 is a planar square. However, the beam member 2 is not limited to this and may be a planar rectangle, for example.
In the above example, the support column 4 is folded around the vertical (front-rear direction) axis, but is not limited thereto, and may be folded around the horizontal (left-right direction) axis, for example.
The rope 5 is a wire rope in the previous example, but is not limited thereto, and may be a chain, for example.
In the above example, the tension adjuster 6 is provided at the end portion of the rope 5, but the tension adjuster 6 is not limited thereto, and may be provided at an intermediate portion of the rope 5, for example.
The pivot means 18 is provided in the second example, but the present invention is not limited thereto, and for example, this may be omitted. In this case, the folding of the support column 4 can be combined by the angle adjusting means 35.
The height adjusting means 40 is provided in the second example. However, the height adjusting means 40 is not limited thereto, and may be omitted, for example. In this case, the front and rear columns 4 need to have a length corresponding to the inclination angle of the vertical beam member 7.

【The invention's effect】
As described above, according to the present invention, the following excellent effects can be obtained.
(1) Vertical and horizontal beam members arranged to form a bottom plane square, joints that connect adjacent beam members, and columns that are provided at each joint and that can be folded from the folding position to the upright position. And two ropes that are detachably mounted between the joints located on the diagonal line, and a tension adjuster that is provided only on one of the ropes and adjusts the tension, so that the column can be folded. Since the rope and tension adjuster are used for the roof structure, the total height during storage can be lowered and the roof structure can be reduced in weight.
(2) Since a single tension adjuster is used, labor and cost required for tension adjustment can be reduced.
