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。 The present invention is used in civil engineering work, agriculture, industry, etc., and is a large bag used for transporting, storing, and storing earth and sand, seeds, powdery material, etc., so-called flexible container bag (also referred to as flexible container bag or flexible container for short). ) Is related to an opening bag holding device that holds the) in an open state 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。 Conventionally, when packing earth and sand, seeds, powdered material, etc. in a bag, a person holds and packs the bag. However, in order to improve work efficiency, if the bag is enlarged, there is a safety problem that a person holds the bag, and the title of the invention of Patent Document 1, "bag holding device", has been proposed.

特開２００７−１９８０１２号公報Japanese Unexamined Patent Publication No. 2007-198012

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, with respect to the title of the invention of Patent Document 1, "bag holding device", since the ground contact portion 5 is wide and the upper upper opening portion 2a is narrowed, the outer surface of the bag body 1 is provided on the opening edge support portion 4. The structure is such that the bag body 1 is 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 bias of the contents housed inside 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。 Further, if the opening edge support portion 4 is tilted outward too much when it is caught, the integrated opening edge support portion 4 and the lower portion connected to the opening edge support portion 4 completely fall down until they come into contact with the ground. Therefore, there is a problem that it takes time and effort to return the integrated opening edge support portion 4 and the lower portion connected to the opening edge support portion 4 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 integrated opening edge support portions 4 and a lower portion connected to them and they cannot be moved in conjunction with each other, the integrated opening edge support portion 4 and the lower portion connected to the opening edge support portion 4 are connected to the lower portion. When expanding the two locations to the outside, it is necessary to expand the two locations separately, which causes a problem that it takes time and effort. Therefore, for these reasons, the removal work after the bag body 1 is caught is 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 integrated square frame, the bag holding device is stable at construction sites, farmlands, wilderness, etc. that are not leveled on a flat surface. There was a problem that it got worse.

The first embodiment will be described with reference to FIGS. 1 to 3. First, the appearance of the opening bag holding device 1 will be described with reference to the perspective view of FIG. The opening bag holding device 1 has a substantially tubular outer shape having a bottom portion, and is composed of a first member 10 and a second member 20 obtained by dividing the substantially tubular 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. Further, 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 connected to each other by two rotating members 30 as rotating portions between the first bottom member 11 and the second bottom member 21. 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 portion will be described in detail later, but the bag attached to the opening bag holding device 1 is an earth and sand, feed, grain, granular or powdery industrial product, etc. ( The purpose is to facilitate the removal of the bag attached to the opening bag holding device 1 when the contents are put in and inflated, and the strength of the material constituting the opening bag holding device 1 is increased. , It can be omitted depending on the mass and specific gravity of the contents to be 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 a metal rod or pipe. For metal materials and pipes, a material and thickness having strength to withstand the mass of the contents packed in the bag held by the opening 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 and 22 and the chord members 13 and 23 welded to both ends of the arc members 12 and 22. Then, the tips of the plurality of beam members 14a, 14b, 14c, 24a, 24b, and 24c bridged from the chord members 13 and 23 toward the arc members 12 and 22 at substantially right angles are connected to the chord members 13 and 23 and the arcs. It is formed by welding to 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 respective arc members 12 and 22 of the first bottom member 11 and the second bottom member 21, and are substantially perpendicular to the arc members 12 and 22. Each of the four stretched pillars 17a, 17b, 17c, 17d, 27a, 27b, 27c, 27d and the middle of the four pillars 17a, 17b, 17c, 17d, 27a, 27b, 27c, 27d. , It is formed of arcuate middle tiers 18 and 28 and upper tiers 19 and 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 for the rotating member 30, two "substantially U-shaped" metal fittings with holes at the two ends are used, and two "substantially U-shaped" shaped openings are mutually formed. A "substantially U-shaped" metal fitting is fitted, bolts are passed through a total of four holes at the end, and the bolts are fastened with nuts. When a commercially available product is used, a shackle, which is a connecting metal fitting such as a wire or a chain, may be used as the "substantially U-shaped" metal fitting having holes at two ends.

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, two bends of the rotating member 30 composed 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 to the vicinity of both ends of the chord members 13 and 23, but they may be welded from the center, or the metal fittings have a "substantially U-shaped" shape. By increasing the material, thickness, and overall width of the bolt, one rotating member 30 may be used. By using 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, reducing the storage space when not in use. 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 the two locations are so-called hooking key fittings. Specifically, metal rings (rings) having holes oriented substantially up and down are welded to both ends of the upper members 19 and 29 of the first rising member 12 and the second rising member 22. Then, using a hook metal fitting having one end processed into a hook and the other end processing into an annular shape, the annularly processed side of the hook metal fitting is attached to a metal ring welded to the arc-shaped upper stage member. The holes provided with 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. By providing the two connecting members 40 having this shape, the upper member 19 of the first rising member 12 and the upper 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。 The opening of the opening bag holding device 1 which is tubular in the upper members 19 and 29 and the two connecting members 40 is a tubular opening bag of the first rising member 12 and the second rising member 22. The outer peripheral portion of the holding device 1 is formed by the first bottom member 11, the second bottom member 21, and the two rotating members 30, and the bottom portion of the opening bag holding device 1 having a tubular shape is formed. As described above, the connecting member 40 may be omitted.

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。 Regarding the rotating member 30 and the connecting member 40, since the first member 10 and the second member 20 are made of metal, they are described as metal, but the first member 10 and the second member 20 are made of synthetic resin. If so, 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 opening bag holding device 1 in the state of FIG. The bag 7 is a flexible container bag in which a durable sheet such as a chemical fiber is formed in a bag shape. The bag 7 is used for storing and transporting the contents of the bag 7. Further, the bag 7 whose contents are earth and sand is used as a sandbag by 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 is square, but the general-purpose product is cylindrical and has a diameter of 900 to 1200 mm and a height of 900 to 1200 mm. The total mass (mass including tare) varies depending on the type of bag. ) 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 putting the contents in the bag 7, of course, it is possible to put the contents manually by using a shovel, a scoop or the like, but considering the amount of contents that can be stored in the bag 7, a machine, for example, a belt Conveyors, hydraulic shovels (backhoes), etc. are used. Therefore, it is difficult to maintain the opened bag 7 in that state from the viewpoints of safety, human physical strength, and work efficiency. Then, an opening 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 opening bag holding device 1, the opening 7a in the bag 7 is fully opened, and the upper member 19 of the first rising member 16 of the opening bag holding device 1 having a predetermined length from the opening 7a. (See FIGS. 1 and 3) and the opening 7a of the bag 7 is projected above the upper member 29 (see FIGS. 1 and 3) of the second rising member 26. Then, the protruding portion 7b on the inner surface of the bag 7 is folded back and put on the outside of the opening bag holding device 1, and the bag 7 is attached to the opening 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 contents are put in the bag 7 and then the bag 7 containing the contents is taken out from the opening bag holding device 1. The protruding portion 7b that was folded back at the positions of the upper members 19 and 29 of the bag 7 is restored. When the contents are put in the bag 7, the body 7c of the bag 7 swells, and the middle portion 18, the upper member 19 of the first rising member 16 and the interrupting portion 28, the upper member of the second rising member 26 are swelled. It sticks out from 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 opening bag holding device 1, it is necessary to disengage the hooks of the two connecting members 40 of the opening bag holding device 1, and in FIG. 3, the connecting member 40 The hook of the hook is removed.

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 opening bag holding device 1, it is assumed that a belt 7d capable of suspending the bag 7 containing the contents as it is is attached to the bag 7. Regarding the belt 7d, the belt 7d is put together on the upper side of the bag 7 in preparation for hanging. When a bag without a belt 7d is used, when the bag is installed in the opening bag holding device 1 of FIG. 2, a 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 only the opening bag holding device 1 of FIG. 3 is cut along the AA cross section and the bag 7 containing the contents is taken out from the opening bag holding device 1 will be described. Further, in FIG. 4, a portion hidden by the bag 7 of the opening 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 two connecting members 40 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 body portion 7c on the lower side of the bag 7 swells a lot. Further, if the protruding portion 7b of the bag 7 is collected in 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 is inflated, the inflated 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, a crane wheel is attached to the belt 7d in a state where the pillar 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. FIG. 5 shows a state in which a hoist crane, a hydraulic shovel (back ho), or the like is used, and a little is lifted directly or by using a hanging auxiliary tool 8 such as a hanging belt or a hanging 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 outward, the first bottom member 11 and the second bottom member of the opening bag holding device 1 are weighed by the weight of the bag 7 containing the contents. Since the 21 and the rotating member 30 are pressed against each other, the first member 10 and the second member 20 do not spread outward. However, when the bag 7 is lifted by the hanging aid 8, the weight of the bag 7 in which the contents are contained disappears, and the pillar members 17a to 27d of the opening 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。 When the pillar 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 rotating member 30, so that the opening bag holding device 1 The first member 10 and the second member 20 of the above are pushed apart while maintaining a substantially right-angled state.

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 area of the upper members 19 and 29 is larger than the opening area of the middle members 18 and 28 of the first member 10 and the second member 20. In other words, the pillar members 17a to 27d spread outward more toward the upper side than the lower 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 or the second member 20 is pressed, the other member 20 is pressed. 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。 As a result, the bag 7 in which the contents are put and inflated is lifted along the pillar members 17a to 27d that are expanded upward. Therefore, even the inflated bag 7 containing the contents is less likely 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 work can be easily performed.

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。 It is a perspective view of the bag 7 in a state of being further lifted with the hanging auxiliary tool 8 attached to the belt 7d of FIG. As described above, the bag 7 inflated with the contents put in the opening bag holding device 1 is difficult to be caught, but even if the bag 7 inflated with the contents put in the middle is caught, the first member. It is a figure which showed that the 1st member 10 and the 2nd member 20 can be further expanded in a fan shape by pulling one of 10 and 2nd member 20 outward.

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 two rotating members 30. Therefore, the first member 10 and the second member 20 are opened in a state of being balanced left and right in a cross-sectional view of a "substantially W-shaped" shape, and depending on the position of the center of gravity of the first member 10 and the second member 20. However, the first member 10 and the second member 20 will not fall to the ground unless they are opened too wide.

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。 The first member 10 and the second member 20 of the opening bag holding device 1 can be easily pulled outward. Even if the opening bag holding device 1 is manufactured with the above contents with a metal rod having a diameter of 13 mm in accordance with a general lexible container bag, the height of the opening bag holding device 1 is about 1 meter. This is because it is easy for an adult to grasp the upper member 19 of the upper member 16 or the upper member 29 of the second rising member 26 and pull it outward by the principle of the pocket.

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。 The first member 10 and the second member 20 of the opening bag holding device 1 can be left 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. If the first member 10 and the second member 20 have substantially the same shape, the production becomes 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。 From the above, when the bag 7 in which the contents are put and the body portion 7c is inflated is lifted, the first member 10 and the second member 20 can be easily caught if the opening bag holding device 1 is caught or is likely to be caught. Can be spread out in a large fan shape. If it is expanded in a large fan shape, the bag 7 with the inflated body 7c can be easily lifted.

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７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。 The state in which the opening bag holding device 1 of FIG. 1 is placed on a flat surface is illustrated, but FIG. 7 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 to put earth and sand, it may be used in an unleveled place such as a mountain or a wilderness. Since the first member 10 and the second member 20 of the opening bag holding device 1 are connected by two rotating members 30 and two connecting members 40, it is a place where there are small stones that are not leveled. However, the opening bag holding device 1 is deformed so that it can be easily and stably placed. Since the opening bag holding device 1 is the same as that in FIG. 1, the same reference numerals are given and the description thereof will be 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)
The opening bag holding device 2 of the second embodiment will be described with reference to FIG. FIG. 5 is a plan view of the opening bag holding device 2. In the opening bag holding device 2, the opening bag holding device 1 is divided into two by the first member 10 and the second member 20, but is divided into three by the three divided members 51, 52, and 53 to have substantially the same size. .. Since it is divided into three parts of approximately the same size, it is easy to manufacture and easy to store when not in use. Further, when the opening bag holding device 2 is opened, it can be opened larger than that of the opening bag holding device 1, and the balance of the opening bag holding device 2 when the opening operation is performed is also improved.

そして、開口袋保持装置２の底部中央部には、回動部材３１が設けられている。回動部材３１は、略三角形の金属板の３辺の略中央部の三か所に、孔の開いた立ち上げを備えており、前記三か所の孔に、３個の「略Ｕの字状」金具がボルトとナットで回動自在に取り付けられている。さらに、回動部材３１の３個の「略Ｕの字状」曲がりを、３分割部材５１、５２、５３の底部材５４、５５、５６の夫々と溶接している。 A rotating member 31 is provided at the center of the bottom of the opening bag holding device 2.

また、３分割部材５１、５２、５３の立上部材５７、５８、５９が夫々、３箇所の連結部材４０で連結されている。これにより、筒状である開口袋保持装置２の開口部が、形成されている。なお、開口袋保持装置２の外周部については、第１の実施形態の開口袋保持装置１の２分割が３分割になっているだけであるので、説明を省略する。また、袋７を取り付け、内容物を入れて取り外す方法については、第１の実施形態の２分割が３分割になっているだけであり、基本的には同じ内容となるので説明を省略する。なお、開口袋保持装置２の底部は３分割されているので、開口袋保持装置１に比較しても整地されてない場所で開口袋保持装置２は安定しやすくなる。 Further, the rising members 57, 58, 59 of the three-divided members 51, 52, 53 are connected by three connecting members 40, respectively. As a result, an opening of the opening bag holding device 2 having a tubular shape is formed. Regarding the outer peripheral portion of the opening bag holding device 2, the description thereof will be omitted because the two divisions of the opening bag holding device 1 of the first embodiment are only divided into three. Further, regarding the method of attaching the bag 7 and inserting and removing the contents, the description thereof will be omitted because the two divisions of the first embodiment are only divided into three and the contents are basically the same. Since the bottom of the opening bag holding device 2 is divided into three parts, the opening bag holding device 2 is more likely to be stable than the opening bag holding device 1 in a place where the ground is not leveled.

（第３の実施形態）
第３の実施形態の開口袋保持装置３について、図９に基づき説明する。図９は開口袋保持装置３の平面図である。開口袋保持装置３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、４分割部材６１、６２、６３、６４で略同じ大きさに４分割されている。略同じ大きさで４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３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３のバランスも良くなる。 (Third Embodiment)
The opening bag holding device 3 of the third embodiment will be described with reference to FIG. FIG. 9 is a plan view of the opening bag holding device 3. In the opening bag holding device 3, the opening bag holding device 1 was divided into two by the first member 10 and the second member 20, but is divided into four by the four divided members 61, 62, 63, and 64 to have substantially the same size. ing. Since it is divided into four parts of approximately the same size, it is easy to manufacture and easy to store when not in use. Further, when the opening bag holding device 3 is opened, it can be opened larger than that of the opening bag holding device 1, and the balance of the opening bag holding device 3 when the opening operation is performed is also improved.

そして、開口袋保持装置３の底部中央部には、回動部材３２が設けられている。回動部材３２は、略四角形の金属板の４辺の略中央部の四か所に、孔の開いた立ち上げを備えており、前記四か所の孔に、４個の「略Ｕの字状」金具がボルトとナットで回動自在に取り付けられている。さらに、回動部材３２の４個の「略Ｕの字状」曲がりを、４分割部材６１、６２、６３、６４の底部材６５、６６、６７、６８の夫々と溶接している。 A rotating member 32 is provided at the center of the bottom of the opening bag holding device 3.
