Description

本発明は、土木工事、農業、工業等に用いられて、土砂や種、粉粒材料等の輸送、収納保管に用いられる大型の袋、所謂フレキシブルコンテナバッグ（略して、フレコンバッグまたはフレコンとも呼ばれる）を、作業を容易にするために開口した状態で保持する開口袋保持装置に関するものである。 INDUSTRIAL APPLICABILITY The present invention is used for civil engineering, agriculture, industry, etc., and is a large bag used for transportation and storage of earth and sand, seeds, powdered materials, so-called flexible container bag (abbreviated as flexible container bag or flexible container). ) For holding an open bag for facilitating work.

従来、袋に土砂や種子、粉粒材料等を詰める場合には、人が保持して詰めていた。しかしながら、作業の効率化が図るために、袋を大きくすると、袋の保持を人が行うことは安全上の問題があり、特許文献１の発明の名称「袋保持装置」が提案されている。 In the past, when a bag was filled with earth and sand, seeds, powdered materials, etc., it was held and packed by a person. However, there is a safety problem in that a person holds the bag if the bag is made large in order to improve work efficiency, and the title "bag holding device" of the invention of Patent Document 1 is proposed.

特開２００７−１９８０１２号公報JP, 2007-198012, A

しかしながら、特許文献１の発明の名称「袋保持装置」については、接地部５が広く、上側の上部開口部２ａが狭くなる構造であることから、開口縁支持部４に袋体１の外面が触れていく構造であり、袋体１の内部に収容した内容物の形状や偏りによっては、開口縁支持部４に袋体１が引っ掛かってしまうと言う問題があった。 However, in the title “bag holding device” of the invention of Patent Document 1, since the grounding portion 5 is wide and the upper upper opening 2a is narrow, the outer surface of the bag 1 is attached to the opening edge supporting portion 4. It is a structure to be touched, and there is a problem that the bag body 1 is caught in the opening edge support portion 4 depending on the shape and deviation of the contents accommodated in the bag body 1.

さらに、引っ掛かってしまった場合に、開口縁支持部４を外側に傾け過ぎると、一体となっている開口縁支持部４とそれに接続する下側の部分は、地面に接触するまで完全に倒れてしまい、一体となっている開口縁支持部４とそれに接続する下側の部分を元の位置まで戻す手間が掛かると言う問題があった。 Furthermore, if the opening edge support 4 is tilted too far in the case of being caught, the integrated opening edge support 4 and the lower part connected to it are completely collapsed until they contact the ground. Therefore, there is a problem that it takes time and effort to return the opening edge support portion 4 and the lower portion connected thereto, which are integrated, to the original position.

また、一体となっている開口縁支持部４とそれに接続する下側の部分は２箇所あり、連動して動かせないので、一体となっている開口縁支持部４とそれに接続する下側の部分の２箇所を外側に広げる場合には、２箇所を夫々別に広げる必要があり、手間が掛かると言う問題があった。そのためこれらのことから、袋体１が引っ掛かった後の取り外し作業が面倒であった。 Further, since there are two opening edge support parts 4 and the lower part connected to them which are integral with each other and cannot be moved in conjunction with each other, the integrated opening edge support part 4 and the lower part connected to it are integrated. However, there is a problem that it takes time and effort to spread the two locations outside respectively. Therefore, from these things, the removal work after the bag body 1 was caught was troublesome.

さらに特許文献１の「袋保持装置」の接地部５は一体となった四角の枠として形成されているので、平面に整地されてない工事現場、農地、荒野などでは、袋保持装置の安定が悪くなると言う問題があった。 Further, since the grounding portion 5 of the "bag holding device" of Patent Document 1 is formed as an integral square frame, the bag holding device is stable at a construction site, farmland, wilderness, etc. where the ground is not leveled on a flat surface. There was a problem of getting worse.

本発明に係る開口袋保持装置の実施の形態について図１乃至図７に基づき説明する。なお、この実施の形態によりこの発明が限定されるものではない。 An embodiment of an opening bag holding device according to the present invention will be described with reference to FIGS. 1 to 7. The present invention is not limited to this embodiment.

（第１の実施形態）
第１の実施形態について、図１乃至図３に基づき説明する。まず、図１の斜視図を用いて開口袋保持装置１の外観を説明する。開口袋保持装置１は大略すると底部を有した略筒状の外形で、前記底部を有した略筒状の外形を、２分割した第一部材１０と第二部材２０で構成されている。 (First embodiment)
The first embodiment will be described based on FIGS. 1 to 3. First, the external appearance of the open bag holding device 1 will be described with reference to the perspective view of FIG. The open bag holding device 1 has a generally cylindrical outer shape having a bottom portion, and is composed of a first member 10 and a second member 20 obtained by dividing the generally cylindrical outer shape having the bottom portion into two parts.

第一部材１０は、第一底部材１１と、第一底部材１１に固定され上方に立ち上げられた第一立上部材１６で、構成されている。また、第二部材２０は、第二底部材２１と、第二底部材２１に固定され上方に立ち上げられた第二立上部材２６で、構成されている。 The first member 10 is composed of a first bottom member 11 and a first rising member 16 fixed to the first bottom member 11 and raised upward. The second member 20 is composed of a second bottom member 21 and a second rising member 26 fixed to the second bottom member 21 and raised upward.

第一部材１０と第二部材２０については、第一底部材１１と第二底部材２１の間において、回動部として２箇所の回動部材３０で相互に接続されている。また、第一立上部材１６と第二立上部材２６の上端の間については、連結部として２箇所の連結部材４０で、第一部材１０と第二部材２０が相互に係合されている。 The first member 10 and the second member 20 are mutually connected between the first bottom member 11 and the second bottom member 21 by two rotating members 30 as rotating parts. Further, between the upper ends of the first rising member 16 and the second rising member 26, the first member 10 and the second member 20 are engaged with each other by two connecting members 40 as connecting portions. ..

なお、連結部として設けられている２箇所の連結部材４０については、詳しくは後述するが、開口袋保持装置１に取り付けた袋が、土砂、飼料、穀物、粒状や粉状の工業製品等（以下、内容物と略す。）を入れて膨らんだ場合に、開口袋保持装置１に取り付けられた袋の取り外しを容易にするためのものであり、開口袋保持装置１を構成する材料の強度や、袋に入れられる内容物の質量や比重によっては省略できる。 The two connecting members 40 provided as the connecting portions will be described in detail later, but the bag attached to the opening bag holding device 1 includes earth and sand, feed, grain, granular or powdered industrial products ( (Hereinafter, abbreviated as "contents") is for facilitating removal of the bag attached to the open bag holding device 1 when the bag is inflated. , It can be omitted depending on the mass and specific gravity of the contents put in the bag.

第一部材１０と第二部材２０は、金属製の棒やパイプを溶接することにより形成されている。金属製の材やパイプについては、開口袋保持装置１で保持される袋に詰められる内容物の質量に耐えられる強度を有した材質及び太さを選択する。よって、強度を満足する場合には合成樹脂の材やパイプでも良い。 The first member 10 and the second member 20 are formed by welding metal rods or pipes. For the metal material and the pipe, a material and a thickness that are strong enough to withstand the mass of the contents packed in the bag held by the open bag holding device 1 are selected. Therefore, if the strength is satisfied, a synthetic resin material or a pipe may be used.

第一底部材１１と第二底部材２１については、円弧材１２、２２と、円弧材１２、２２の両端に溶接された弦材１３、２３で、略半円形の枠が形成されている。そして、弦材１３、２３から略直角に円弧材１２、２２に向かって橋渡しをした複数の梁材１４ａ、１４ｂ、１４ｃ、２４ａ、２４ｂ、２４ｃの夫々の先端を、弦材１３、２３と円弧材１２、２２に溶接することにより形成されている。 Regarding the first bottom member 11 and the second bottom member 21, a substantially semicircular frame is formed by the arc members 12, 22 and the chord members 13, 23 welded to both ends of the arc members 12, 22. The tip ends of each of the plurality of beam members 14a, 14b, 14c, 24a, 24b, and 24c bridging from the chord members 13 and 23 toward the arc members 12 and 22 at substantially right angles to the chord members 13 and 23 and the arc. It is formed by welding the materials 12 and 22.

第一立上部材１２と第二立上部材２２については、第一底部材１１と第二底部材２１の夫々の円弧材１２、２２の夫々に溶接し、円弧材１２、２２から略垂直に延伸させた各４本の柱材１７ａ、１７ｂ、１７ｃ、１７ｄ、２７ａ、２７ｂ、２７ｃ、２７ｄと、四本の柱材１７ａ、１７ｂ、１７ｃ、１７ｄ、２７ａ、２７ｂ、２７ｃ、２７ｄの中ほどと、上端に溶接した、円弧状の中段材１８、２８と上段材１９、２９で形成されている。 The first rising member 12 and the second rising member 22 are welded to the arc members 12 and 22 of the first bottom member 11 and the second bottom member 21, respectively, so as to be substantially perpendicular to the arc members 12 and 22. Each of the four pillars 17a, 17b, 17c, 17d, 27a, 27b, 27c, 27d stretched and the middle of the four pillars 17a, 17b, 17c, 17d, 27a, 27b, 27c, 27d. It is formed by arcuate middle step members 18, 28 and upper step members 19, 29 welded to the upper end.

回動部材３０については、「略Ｕの字状」金具の２箇所の端部に孔を開けたものを２個用い、その「略Ｕの字状」の形状の開口部相互に２個の「略Ｕの字状」の金具を嵌め込み、前記端部の計４箇所の孔にボルトを貫通させてナットにより止めたものである。２箇所の端部に孔が開けられた「略Ｕの字状」金具は、市販品を用いる場合には、ワイヤーやチェーン等の連結金具であるシャックルを用いても良い。 As the rotating member 30, two "substantially U-shaped" metal fittings having holes at two end portions are used, and two of the "substantially U-shaped" shaped openings are mutually provided. A "substantially U-shaped" metal fitting is fitted, bolts are passed through a total of four holes at the end portion, and fixed by nuts. When a commercially available product is used as the “substantially U-shaped” metal fitting having holes at two ends, a shackle which is a connecting metal fitting such as a wire or a chain may be used.

そして、２個の「略Ｕの字状」金具からなる回動部材３０の２箇所曲がりを、第一底部材１１と第二底部材２１夫々の弦材１３、２３に溶接している。本実施形態においては、２個の回動部材３０を、弦材１３、２３の両端近傍に溶接しているが、中央よりに溶接しても良いし、「略Ｕの字状」の金具と、ボルトの材質、太さ、全体の幅を大きくすることで、１個の回動部材３０としても良い。２箇所の回動部材３０にボルト・ナットを用いていることで、開口袋保持装置１を第一部材１０と第二部材２０に分割することが可能となり、不使用時の保管の場所を減らすことが可能となる。 Then, the two bendings of the rotating member 30 made of two "substantially U-shaped" metal fittings are welded to the chord members 13 and 23 of the first bottom member 11 and the second bottom member 21, respectively. In the present embodiment, the two rotating members 30 are welded near the both ends of the chord members 13 and 23, but they may be welded from the center or with a “substantially U-shaped” metal fitting. The rotating member 30 may be formed by increasing the material, thickness, and overall width of the bolt. By using the bolts and nuts for the two rotating members 30, the opening bag holding device 1 can be divided into the first member 10 and the second member 20, and the storage place when not in use can be reduced. It becomes possible.

２箇所に設けられている２個の連結部材４０については、所謂引っ掛け鍵金具である。具体的には、第一立上部材１２と第二立上部材２２の上段材１９、２９の両端に、孔の向きが略上下とした金属環（輪）を溶接されている。そして、一方の端が鉤（フック）、他方の端を環状に加工した鉤金具を用い、前記鉤金具の環状に加工した側を、前記円弧状の上段材に溶接した金属環に対して、互いに設けられている孔を鎖状にして結合している。さらに、鉤金具の鉤を他方の円弧状の上段材に溶接した金属環に引っ掛けている。そしてこの形状の２個の連結部材４０を備えていることで、第一立上部材１２の上段材１９と、第二立上部材２２の上段材２９を連結することができる。 The two connecting members 40 provided at two locations are so-called hook key fittings. Specifically, metal rings (rings) whose holes are oriented substantially vertically are welded to both ends of the upper step members 19 and 29 of the first rising member 12 and the second rising member 22, respectively. Then, one end is a hook (hook), using a hook metal fitting that the other end is processed into a ring, the ring-shaped side of the hook metal fitting, to the metal ring welded to the arc-shaped upper step material, The holes provided to each other are connected in a chain shape. Further, the hook of the hook metal fitting is hooked on the metal ring welded to the other arc-shaped upper member. Since the two connecting members 40 having this shape are provided, the upper step member 19 of the first rising member 12 and the upper step member 29 of the second rising member 22 can be connected.

この上段材１９、２９と２箇所の連結部材４０で、筒状である開口袋保持装置１の開口部が、第一立上部材１２と第二立上部材２２で、筒状である開口袋保持装置１の外周部が、第一底部材１１、第二底部材２１と２箇所の回動部材３０で、筒状である開口袋保持装置１の底部が、形成されている。なお、前述の様に、連結部材４０を省略しても良い。 With the upper members 19, 29 and the connecting members 40 at two locations, the opening of the tubular opening bag holding device 1 is the tubular of the first rising member 12 and the second rising member 22. The outer peripheral portion of the holding device 1 is composed of a first bottom member 11, a second bottom member 21 and two rotating members 30, and the bottom of the tubular opening bag holding device 1 is formed. The connecting member 40 may be omitted as described above.

なお、回動部材３０と連結部材４０については、第一部材１０と第二部材２０が金属製としているので、金属として説明しているが、第一部材１０と第二部材２０を合成樹脂とする場合には、同じ合成樹脂として、接着、溶着、締結等により取り付けても良い。 The rotating member 30 and the connecting member 40 are described as metal because the first member 10 and the second member 20 are made of metal, but the first member 10 and the second member 20 are made of synthetic resin. In this case, the same synthetic resin may be attached by adhesion, welding, fastening or the like.

図２は、図１の状態の開口袋保持装置１に、袋７を装着した状態を図示している。袋７は、化学繊維等の丈夫なシートを袋状に形成したフレキシブルコンテナバッグである。袋７の用途としては、内容物を入れて、その保管や輸送等に用いられる。また、内容物が土砂である袋７は、それ自体を土嚢として用いられている。 FIG. 2 illustrates a state in which the bag 7 is attached to the open bag holding device 1 in the state of FIG. The bag 7 is a flexible container bag in which a strong sheet of chemical fiber or the like is formed into a bag shape. The bag 7 is used for storing and transporting the contents. The bag 7 whose content is earth and sand is used as a sandbag itself.

袋７の大きさは、角型のものもあるが、汎用品は円筒形で直径９００〜１２００ｍｍ、高さ９００〜１２００ｍｍ程度であり、入れられるものの種類によっても異なるが、総質量（風袋込質量）は１トン程度になる。 The size of the bag 7 may be a square type, but a general-purpose product has a cylindrical shape with a diameter of 900 to 1200 mm and a height of 900 to 1200 mm, which varies depending on the type of the bag, but the total mass (mass including the tare weight). ) Is about 1 ton.

袋７に、内容物を入れる場合には、もちろん人力でシャベル・スコップ等を用いて入れることも可能であるが、前記袋７に収納可能な内容物の量から考えて、機械、例えば、ベルトコンベアや、油圧シャベル（バックホー）等が用いられている。そのため、開口させた袋７をその状態で維持することは、安全性、人間の体力、作業の効率性の面から難しい。そして、無人で、開口させた袋７を保持できる開口袋保持装置１が必要となる。 When the contents are put in the bag 7, it is of course possible to put the contents manually by using a shovel, a scoop or the like, but in consideration of the amount of the contents which can be stored in the bag 7, a machine such as a belt is used. Conveyors and hydraulic shovels (backhoes) are used. Therefore, it is difficult to maintain the opened bag 7 in that state in terms of safety, physical strength of a person, and work efficiency. Then, an open bag holding device 1 capable of holding the opened bag 7 unattended is required.

開口袋保持装置１に袋７を取り付ける場合には、袋７にある開口部７ａを全開にして、開口部７ａから所定の長さ開口袋保持装置１の第一立上部材１６の上段材１９（図１、図３参照）と、第二立上部材２６の上段材２９（図１、図３参照）よりも上に袋７の開口部７ａを食み出させる。そして、袋７の内側の面の食み出した部分７ｂを折り返し、開口袋保持装置１の外側に被せて、開口袋保持装置１に袋７を装着している。 When the bag 7 is attached to the open bag holding device 1, the opening 7a in the bag 7 is fully opened, and the upper step member 19 of the first rising member 16 of the open bag holding device 1 having a predetermined length from the opening 7a. (See FIGS. 1 and 3) and the upper portion 29 of the second rising member 26 (see FIGS. 1 and 3), the opening 7a of the bag 7 is projected. Then, the protruding portion 7b on the inner surface of the bag 7 is folded back and covered on the outside of the open bag holding device 1, and the bag 7 is attached to the open bag holding device 1.

図３は、袋７に内容物を入れた後、開口袋保持装置１から、内容物の入った袋７を取り出す場合を図示したものである。袋７の上段材１９、２９の位置で折り返されていた食み出した部分７ｂを元に戻している。袋７に内容物を入れた場合には、袋７の胴部７ｃは膨らみ、第一立上部材１６の中段部１８、上段材１９と、第二立上部材２６の中断部２８、上段材２９よりも外側に食み出す。 FIG. 3 illustrates a case where the bag 7 containing the contents is taken out from the opening bag holding device 1 after the contents are put into the bag 7. The protruding portion 7b folded back at the position of the upper members 19 and 29 of the bag 7 is returned to the original position. When the contents are put in the bag 7, the body portion 7c of the bag 7 swells, and the middle step portion 18, the upper step member 19 of the first rising member 16 and the interruption portion 28, the upper step member 26 of the second rising member 26. It sticks out to the outside of 29.

そのため、内容物が入った袋７を開口袋保持装置１から取り出すためには、開口袋保持装置１の２箇所の連結部材４０の鉤の引っ掛けを外す必要があり、図３において、連結部材４０の鉤の引っ掛けが外されている。 Therefore, in order to take out the bag 7 containing the contents from the open bag holding device 1, it is necessary to remove the hooks of the hooks of the connecting members 40 at the two positions of the open bag holding device 1. In FIG. The hook has been unhooked.

また、袋７を開口袋保持装置１から取り出すために、内容物を入れた状態の袋７をそのまま吊り下げが行えるベルト７ｄが袋７に取り付けられているものとしている。このベルト７ｄについては、吊り下げを行うための準備として袋７の上側にベルト７ｄをまとめてある。ベルト７ｄが付いてない袋を使用する場合には、図２の開口袋保持装置１に袋を設置する場合に、最初に袋の下側に吊りベルトを入れて袋の取り出し作業を行う。 Further, in order to take out the bag 7 from the open bag holding device 1, it is assumed that the bag 7 is attached to the bag 7 so that the bag 7 in which the contents are put can be suspended as it is. The belt 7d is arranged on the upper side of the bag 7 in preparation for hanging. When the bag without the belt 7d is used, when the bag is installed in the opening bag holding device 1 of FIG. 2, the hanging belt is first put under the bag to take out the bag.

図３の開口袋保持装置１だけをＡ−Ａ断面で切断した図４を用いて、開口袋保持装置１から内容物を入れた状態の袋７を取り出す状態について説明する。また、図４において、開口袋保持装置１の袋７で隠れている部分については、破線で図示している。 A state in which the bag 7 containing the contents is taken out from the open bag holding device 1 will be described with reference to FIG. 4 in which only the open bag holding device 1 of FIG. Further, in FIG. 4, the portion hidden by the bag 7 of the open bag holding device 1 is shown by a broken line.

２箇所の連結部材４０が外されると、袋７は入れられている内容物の重さにより、袋７の胴部７ｃが膨らむことになる。特に袋７の下側の胴部７ｃが多く膨らむことになる。さらに、袋７の食み出した部分７ｂを袋７の中央に集めて開口部７ａをとじれば、さらに袋７の胴部７ｃが膨らむことになる。この場合、袋７の胴部７ｃが膨らむと、膨らんだ胴部７ｃは、開口袋保持装置１の柱材１７ａ、１７ｂ、１７ｃ、１７ｄ、２７ａ、２７ｂ、２７ｃ、２７ｄを外側に向かって押すことになる。 When the connecting members 40 at the two locations are removed, the body portion 7c of the bag 7 swells due to the weight of the contents contained in the bag 7. In particular, the lower body portion 7c of the bag 7 is largely inflated. Further, if the protruding portion 7b of the bag 7 is gathered at the center of the bag 7 and the opening 7a is closed, the body portion 7c of the bag 7 is further expanded. In this case, when the body portion 7c of the bag 7 swells, the bulged body portion 7c pushes the pillar members 17a, 17b, 17c, 17d, 27a, 27b, 27c, 27d of the opening bag holding device 1 outward. become.

図４で、開口袋保持装置１の柱材１７ａ〜２７ｄを外側に向かって押された状態で、袋７のベルト７ｄが袋７の上側にまとめられている状態で、ベルト７ｄにクレーン車、ホイストクレーン、油圧シャベル（バックホー）等の吊り上げ装置を用い、直接または吊り下げベルトや吊り下げ用ワイヤー等の吊り下げ補助具８を使用して少し吊り上げた状態を図示したものが図５である。 In FIG. 4, the column members 17a to 27d of the opening bag holding device 1 are pushed outward, and the belt 7d of the bag 7 is gathered on the upper side of the bag 7 in a state that the crane truck is attached to the belt 7d. FIG. 5 shows a state in which a hoisting crane, a hydraulic shovel (backhoe), or other hoisting device is used to slightly hoist the product, either directly or by using a hoisting aid such as a hoisting belt or hoisting wire.

開口袋保持装置１の柱材１７ａ〜２７ｄが外側に押されていても、内容物を入れた状態の袋７の重さで、開口袋保持装置１の第一底部材１１と第二底部材２１、及び回動部材３０は押し付けられているので、第一部材１０と第二部材２０は外側に向かって広がらない。しかしながら、吊り補助具８で、袋７が吊り上げられると、内容物を入れた状態の袋７の重さはなくなり、開口袋保持装置１の柱材１７ａ〜２７ｄが外側に押されるだけの状態になる。 Even if the pillar members 17a to 27d of the opening bag holding device 1 are pushed to the outside, the weight of the bag 7 with the contents put therein causes the first bottom member 11 and the second bottom member of the opening bag holding device 1 to move. Since the 21 and the rotating member 30 are pressed, the first member 10 and the second member 20 do not spread outward. However, when the bag 7 is lifted by the lifting aid 8, the weight of the bag 7 containing the contents is lost, and the column members 17a to 27d of the open bag holding device 1 are only pushed outward. Become.

開口袋保持装置１の柱材１７ａ〜２７ｄが外側に押されるだけの状態になれば、開口袋保持装置１は、回動部材３０で回動自在に接続されているので、開口袋保持装置１の第一部材１０と第二部材２０は、略直角の状態を保ちながら、押し広げられることになる。 If the column members 17a to 27d of the opening bag holding device 1 are only pushed outward, the opening bag holding device 1 is rotatably connected by the turning member 30, and thus the opening bag holding device 1 The first member 10 and the second member 20 are expanded while being held at a substantially right angle.

そのため、第一部材１０と第二部材２０の中段材１８、２８の開口面積よりも、上段材１９、２９の開口面積の方が大きくなる。言い換えれば、柱材１７ａ〜２７ｄは、下側よりも上側に向かって外側に大きく広がることになる。なお、この場合、第一部材１０と第二部材２０は回動部材３０によってリンクする構造となっているので、第一部材１０またはと第二部材２０の一方だけ押されている場合でも、他方側についても、広げられることになる。 Therefore, the opening areas of the upper step members 19 and 29 are larger than the opening areas of the middle step members 18 and 28 of the first member 10 and the second member 20. In other words, the pillars 17a to 27d are spread wider outward from the lower side toward the upper side. In this case, since the first member 10 and the second member 20 are linked by the rotating member 30, even if only one of the first member 10 and the second member 20 is pressed, the other The side will also be expanded.

これらにより、内容物が入れられて膨らんだ袋７は、上側に向かって拡げられた柱材１７ａ〜２７ｄに沿いながら、吊り上げられることになる。そのため、内容物が入れられて膨らんだ袋７であっても、開口袋保持装置１の第一立上部材１６と第二立上部材２６に引っ掛かり難くなり、吊り上げ作業が楽に行える。 By these, the bag 7 in which the contents are put in and swelled is lifted up along the pillar members 17a to 27d which are expanded toward the upper side. Therefore, even if the bag 7 is inflated with the contents, it is difficult for the bag to be caught by the first rising member 16 and the second rising member 26 of the opening bag holding device 1, and the lifting operation can be performed easily.

図５のベルト７ｄに吊り補助具８を取り付けられた状態で、さらに袋７を吊り上げ状態の斜視図である。前述の様に開口袋保持装置１に、内容物が入れられて膨らんだ袋７は引っ掛かり難いが、もし途中で内容物が入れられて膨らんだ袋７引っ掛かった場合であっても、第一部材１０と第二部材２０の何れかの一方を外側に向かって引っ張れば、第一部材１０と第二部材２０はさらに大きく扇状に広げることができることを図示した図である。 FIG. 6 is a perspective view showing a state in which a lifting aid 8 is attached to the belt 7 d of FIG. 5 and the bag 7 is further lifted. As described above, the bag 7 that is inflated due to the contents put therein is difficult to be caught by the opening bag holding device 1, but even if the bag 7 that is inflated due to the contents being put in the middle is caught by the first member. It is the figure which illustrated that if either one of 10 and the 2nd member 20 is pulled toward the outer side, the 1st member 10 and the 2nd member 20 can be expanded further to fan shape further.

開口袋保持装置１は、第一部材１０と第二部材２０は、２箇所の回動部材３０で第一底部材１１と第二底部材２１が接続されているリンク形状である。そのため、第一部材１０と第二部材２０は、断面視「略Ｗの字状」形状で左右釣り合った状態で開いて行くことになり、第一部材１０と第二部材２０の重心の位置によっても異なるが、大きく開き過ぎなければ、第一部材１０と第二部材２０が地面に倒れてしまうことはない。 In the opening bag holding device 1, the first member 10 and the second member 20 have a link shape in which the first bottom member 11 and the second bottom member 21 are connected by the rotating members 30 at two positions. Therefore, the first member 10 and the second member 20 open in a state of being cross-sectionally “substantially W-shaped” in a laterally balanced manner, and depending on the position of the center of gravity of the first member 10 and the second member 20. Although it is also different, the first member 10 and the second member 20 will not fall to the ground unless they are opened too much.

開口袋保持装置１の第一部材１０と第二部材２０を楽に外側に引っ張れることについて説明する。開口袋保持装置１を一般的なレキシブルコンテナバッグに合わせて直径１３ｍｍの金属棒で前述の内容で製作したとしても、開口袋保持装置１の高さは、１メートル程度になるので、第一立上部材１６の上段材１９または第二立上部材２６の上段材２９を掴んで外側に引っ張ることは、成人であれば梃の原理で楽に行えるからである。 It will be described how to easily pull the first member 10 and the second member 20 of the opening bag holding device 1 to the outside. Even if the opening bag holding device 1 is made of a metal rod having a diameter of 13 mm in accordance with a general flexible container bag as described above, the height of the opening bag holding device 1 is about 1 meter. This is because it is easy for an adult to grasp and pull the upper step member 19 of the upper member 16 or the upper step member 29 of the second rising member 26 outward by the lever principle.

開口袋保持装置１の第一部材１０と第二部材２０を扇状に開らいたままとすることもできる。これは、第一部材１０と第二部材２０の形状がほぼ同じものが、回動部材３０を軸としてリンクしており、第一部材１０と第二部材２０でのバランスが取れるからである。なお、第一部材１０と第二部材２０がほぼ同じ形状であれば、製作も容易となる。 It is also possible to leave the first member 10 and the second member 20 of the opening bag holding device 1 open in a fan shape. This is because the first member 10 and the second member 20 having substantially the same shape are linked with the rotating member 30 as an axis, and the first member 10 and the second member 20 can be balanced. In addition, if the first member 10 and the second member 20 have substantially the same shape, manufacturing is easy.

以上から、内容物が入れられて胴部７ｃが膨らんだ袋７の吊り上げ作業を行う場合に、開口袋保持装置１に引っ掛かるまたは引っ掛かるおそれがあれば、容易に第一部材１０と第二部材２０を大きく扇状に広げることができる。大きく扇状に拡げられれば、胴部７ｃが膨らんだ袋７の吊り上げ作業が簡単に行えることになる。 As described above, when the bag 7 having the contents 7 put therein and the body portion 7c inflated is lifted, if the bag 7 is caught or may be caught by the opening bag holding device 1, the first member 10 and the second member 20 can be easily carried out. Can be widely fanned out. If it is expanded in a fan shape, the lifting operation of the bag 7 having the inflated body portion 7c can be easily performed.

図１の開口袋保持装置１が平面に置かれている状態を図示しているが、図５は、第一部材１０よりも少し高い位置に第二部材２０がある状態を図示している。土砂を入れることに開口袋保持装置１を使用する場合には、山や原野等の整地されてない場所で使用する場合もある。開口袋保持装置１の第一部材１０と第二部材２０は、２箇所の回動部材３０と２箇所の連結部材４０で接続されているので、整地されてない小さな石がある場所であっても、開口袋保持装置１が変形して、簡単に安定して置くことが可能となる。開口袋保持装置１については、図１と同一であるので同一の符号を附して説明を省略する。 1 illustrates a state in which the open bag holding device 1 of FIG. 1 is placed on a flat surface, but FIG. 5 illustrates a state in which the second member 20 is located at a position slightly higher than the first member 10. When the opening bag holding device 1 is used for putting earth and sand, it may be used in a place such as a mountain or the wilderness where the ground is not leveled. Since the first member 10 and the second member 20 of the opening bag holding device 1 are connected by the rotating member 30 at two places and the connecting member 40 at two places, it is a place where there is a small stone that is not leveled. Also, the opening bag holding device 1 is deformed and can be easily and stably placed. Since the open bag holding device 1 is the same as that in FIG. 1, the same reference numeral is given and its description is omitted.

（第２の実施形態）
第２の実施形態の開口袋保持装置２について、図８に基づき説明する。図５は開口袋保持装置２の平面図である。開口袋保持装置２は、開口袋保持装置１が、第一部材１０と第二部材２０で２分割されていたが、３分割部材５１、５２、５３で略同じ大きさに３分割されている。略同じ大きさで３分割されていることで製作も容易であり、不使用時の収納も簡単になる。また、開口袋保持装置２を開く場合に開口袋保持装置１に比較して大きくが開くことが可能となり、開く作業を行う場合の開口袋保持装置２のバランスも良くなる。 (Second embodiment)
