（実施形態１） Embodiments of a sheet stopper according to the present invention will be described below with reference to the accompanying drawings. In addition, this invention is not limited to the following embodiment.
(Embodiment 1)

図１〜図４に示すように、シート止め具１は、筒状の第１嵌着部１０と、その下方に位置する筒状の第２嵌着部２０と、それらの内側端部に取り付けられた半円弧状の連結部３０とで構成されている。 As shown in FIGS. 1 to 4, the sheet stopper 1 is attached to a cylindrical first fitting portion 10, a cylindrical second fitting portion 20 located below the first fitting portion 10, and inner end portions thereof. It is comprised with the semicircular arc-shaped connection part 30 made.

ここで、第１嵌着部１０、第２嵌着部２０および連結部３０は、同一材料で一体成型されてもよいし、同一材料または異なる材料で別個に作成し、それらを接着等を用いて接続して形成してもよい。なお、これらの材質は弾力性を有するものであれば特に限定されない。これらの材質としては、樹脂や金属等で構成してもよく、例えばポリエチレン、ポリプロピレン、ステンレス鋼、塩化ビニール、ポリスチレン、ＡＢＳ樹脂、アクリル、ナイロン、ポリカーボネイト、ポリウレタンおよびこれらの表面にメッキ処理を施したもの等が挙げられる。 Here, the 1st fitting part 10, the 2nd fitting part 20, and the connection part 30 may be integrally molded with the same material, or it makes them separately with the same material or different materials, and uses them etc. for adhesion | attachment etc. And may be connected. These materials are not particularly limited as long as they have elasticity. These materials may be made of resin, metal, etc., for example, polyethylene, polypropylene, stainless steel, vinyl chloride, polystyrene, ABS resin, acrylic, nylon, polycarbonate, polyurethane, and their surfaces are plated. And the like.

まず、第１嵌着部１０について説明する。第１嵌着部１０は、断面Ｕ字状を成し、パイプ状の支柱部材を挟んで挟持する第１挟持部１１と、軸線方向に開口した第１開口部１２と、支柱部材と嵌合する第１内周面（断面Ｕ字状）１３が形成されている。第１開口部１２の開口方向（Ａ方向）の両端部には第１係止部１４がそれぞれ形成されている。 First, the 1st fitting part 10 is demonstrated. The first fitting portion 10 has a U-shaped cross section, and is fitted to the first holding portion 11 that holds the pipe-like strut member and the first opening portion 12 that is opened in the axial direction, and the strut member. A first inner peripheral surface (a U-shaped cross section) 13 is formed. First locking portions 14 are formed at both ends of the first opening 12 in the opening direction (A direction).

第１内周面１３の第１開口部１２の対向する位置（第１底部）には、図５に示すように、軸線方向（Ｂ方向）に所定の長さを有する付勢部１３１が設けられていると共に、第１内周面１３の第１底部と第１開口部１２との間の対向する位置にも、付勢部１３２が２つ設けられている。このような付勢部１３２を第１内周面１３上に設けることによって、異なる３方向から支柱部材が固定される（付勢される）ことになるので、支柱部材と、第１嵌着部１０との嵌着がさらに強くなる。その結果、支柱部材と、第１嵌着部との嵌着がさらに外れ難くなる。 As shown in FIG. 5, an urging portion 131 having a predetermined length in the axial direction (B direction) is provided at a position (first bottom portion) of the first inner peripheral surface 13 that faces the first opening 12. In addition, two urging portions 132 are also provided at opposing positions between the first bottom portion of the first inner peripheral surface 13 and the first opening portion 12. By providing such a biasing portion 132 on the first inner peripheral surface 13, the column member is fixed (biased) from three different directions, so the column member and the first fitting portion The fitting with 10 is further strengthened. As a result, the fitting between the column member and the first fitting portion is further difficult to come off.

また、第１嵌着部１０の軸線方向（Ｂ方向）の略中央部の外周面には、外周面に沿って突出する断面凹状の突部１５が形成されており、その突部の凹部内には、金属製の剛性強化部１６が嵌合されている。 Further, a projecting portion 15 having a concave cross section projecting along the outer peripheral surface is formed on the outer peripheral surface of the substantially central portion in the axial direction (B direction) of the first fitting portion 10, Is fitted with a metal rigidity reinforcing portion 16.

剛性強化部１６は線状部材を屈曲させてＵ字状を成している。そして、そのＵ字状の内周面の径は、第１嵌着部の外周面の径よりも小さくなっており、突部１５が形成されている効果と合わさって、第１嵌着部１０の開口部１２を開口する方向に対する剛性をより向上させることができるようになっている。 The rigidity reinforcing portion 16 is U-shaped by bending a linear member. And the diameter of the U-shaped inner peripheral surface is smaller than the diameter of the outer peripheral surface of the first fitting portion, and combined with the effect of forming the protrusion 15, the first fitting portion 10. The rigidity in the direction of opening the opening 12 can be further improved.

さらに、第１係止部１４の開口方向の幅は、軸線方向の端部に向かうにつれて小さくなっている。その結果、第１開口部１２の開口幅は、軸線方向の端部側に向かって広がっているので、第１係止部１４の軸線方向の端部から支柱部に第１嵌着部１０を嵌合させると、第１嵌着部１０を支柱部にスムーズに嵌着させることができると共に、逆の操作を行うことによって、支柱部から第１嵌着部１０をスムーズに脱着させることができるようになっている。 Furthermore, the width in the opening direction of the first locking portion 14 becomes smaller toward the end in the axial direction. As a result, since the opening width of the first opening 12 is widened toward the end in the axial direction, the first fitting portion 10 is moved from the end in the axial direction of the first locking portion 14 to the support column. When fitted, the first fitting portion 10 can be smoothly fitted to the column portion, and the first fitting portion 10 can be smoothly detached from the column portion by performing the reverse operation. It is like that.

なお、第１嵌着部１０の厚みは、十分な強度と弾性を有するのであれば特に限定されない。 In addition, the thickness of the 1st fitting part 10 will not be specifically limited if it has sufficient intensity | strength and elasticity.

次に、第２嵌着部２０について説明する。第２嵌着部２０は、図１〜図４に示すように、第１嵌着部１０と同様に、断面Ｕ字状を成し、支柱部材を挟んで挟持する第２挟持部２１と、軸線方向に開口した第２開口部２２と、支柱部材と嵌合する第２内周面（断面Ｕ字状）２３が形成されている。第２開口部２２の開口方向（Ａ方向）の両端部には第２係止部２４がそれぞれ形成されている。 Next, the 2nd fitting part 20 is demonstrated. As shown in FIGS. 1 to 4, the second fitting portion 20 has a U-shaped cross section, like the first fitting portion 10, and a second clamping portion 21 that sandwiches the strut member, A second opening 22 that opens in the axial direction and a second inner peripheral surface (a U-shaped cross section) 23 that fits with the column member are formed. Second locking portions 24 are formed at both ends in the opening direction (A direction) of the second opening 22.

第２内周面２３の第２開口部２２の対向する位置（第２底部）には、図６に示すように、軸線方向（Ｂ方向）に所定の長さを有する付勢部２３１が設けられていると共に、第２内周面２３の第１底部と第２開口部２２との間の対向する位置にも、付勢部２３２が２つ設けられている。このように付勢部２３２を第２内周面上に設けることによって、異なる３方向から支柱部材が固定される（付勢される）ことになるので、支柱部材と、第２嵌着部２０との嵌着がさらに強くなる。その結果、支柱部材と、第２嵌着部２０との嵌着がさらに外れ難くなる。 As shown in FIG. 6, an urging portion 231 having a predetermined length in the axial direction (B direction) is provided at a position (second bottom portion) of the second inner peripheral surface 23 facing the second opening 22. In addition, two urging portions 232 are also provided at positions facing each other between the first bottom portion of the second inner peripheral surface 23 and the second opening portion 22. By providing the urging portion 232 on the second inner peripheral surface in this manner, the column member is fixed (biased) from three different directions, so that the column member and the second fitting portion 20 are fixed. And the fit becomes even stronger. As a result, the fitting between the support member and the second fitting part 20 is further difficult to come off.

また、第２嵌着部２０の第２開口部２２の左右両側部に第２開口部２２の反対側方向に突出する２つの摘み片２５がそれぞれ設けられている。各摘み片２５の対向する表面２６には、図２に示すように、第２開口部２２の反対側方向に伸びる線状の凸部２７が３つ（両端部近傍に２つ、中央部に１つ）それぞれ形成されている。これらの凸部２７を形成することによって、摘み片２５の剛性（強度）が高くなるので、摘み片２５を内向きに綴じる際に摘み片２５自体が屈曲することがない。その結果、スムーズに開口部を開拡することができる。なお、各摘み片２５の対向する表面の逆側の表面２８には、図４に示すように、軸線方向に伸びる複数の凸部で構成される摩擦部２９が形成されており、摘み片２５を把持する際に、指が滑らないようになっている。 In addition, two knobs 25 that protrude in the direction opposite to the second opening 22 are provided on both left and right sides of the second opening 22 of the second fitting part 20. As shown in FIG. 2, the surface 26 facing each knob 25 has three linear protrusions 27 extending in the direction opposite to the second opening 22 (two in the vicinity of both ends and two in the center). 1) Each is formed. By forming these convex portions 27, the rigidity (strength) of the knob 25 is increased, so that the knob 25 itself is not bent when the knob 25 is bound inward. As a result, the opening can be smoothly expanded. In addition, as shown in FIG. 4, the friction part 29 comprised by the some convex part extended in an axial direction is formed in the surface 28 on the opposite side to the surface where each knob 25 opposes, and the knob 25 When gripping the finger, the finger is prevented from slipping.

さらに、第２係止部２４の開口方向の幅は、軸線方向の端部に向かうにつれて小さくなっている。その結果、第２開口部２２の開口幅は、軸線方向の端部側に向かって広がっているので、第２係止部２４の軸線方向の端部から支柱部に第１嵌着部１０を嵌合させると、第１嵌着部１０を支柱部にスムーズに嵌着させることができると共に、逆の操作を行うことによって、支柱部から第２嵌着部２０をスムーズに脱着させることができるようになっている。 Further, the width of the second locking portion 24 in the opening direction is reduced toward the end in the axial direction. As a result, since the opening width of the second opening 22 is widened toward the end in the axial direction, the first fitting portion 10 is moved from the end in the axial direction of the second locking portion 24 to the support column. When fitted, the first fitting portion 10 can be smoothly fitted to the column portion, and the second fitting portion 20 can be smoothly detached from the column portion by performing the reverse operation. It is like that.

ここで、第１内周面１３の径は、第２内周面２３の径よりも小さくなっており、第２嵌着部２０と比較して、第１嵌着部１０を支柱部材に強固に嵌着させることができるようになっている。 Here, the diameter of the first inner peripheral surface 13 is smaller than the diameter of the second inner peripheral surface 23, and the first fitting portion 10 is stronger than the second fitting portion 20 in the support member. It can be made to fit in.

なお、第２嵌着部２０の厚みも、第１嵌着部１０と同様に、十分な強度と弾性を有するのであれば特に限定されない。 The thickness of the second fitting portion 20 is not particularly limited as long as it has sufficient strength and elasticity, like the first fitting portion 10.

さらに、連結部３０について説明する。連結部３０は、第１嵌着部１０の第１開口部１２や第２嵌着部２０の第２開口部２２に対して凹部を有する半円弧状を成している。そして、連結部３０は、第１嵌着部１０の第２嵌着部２０側の端部と、第２嵌着部２０の第１嵌着部１０側の端部とに接続されており、第２嵌着部の脱着に応じて容易に屈曲できるようになっている。 Furthermore, the connection part 30 is demonstrated. The connecting portion 30 has a semicircular arc shape having a recess with respect to the first opening portion 12 of the first fitting portion 10 and the second opening portion 22 of the second fitting portion 20. And the connection part 30 is connected to the edge part by the side of the 2nd fitting part 20 of the 1st fitting part 10, and the edge part by the side of the 1st fitting part 10 of the 2nd fitting part 20, It can be easily bent according to the attachment / detachment of the second fitting portion.

なお、連結部３０の厚みも特に限定されず、弾力性を有し、かつ第１嵌着部１０と第２嵌着部２０とを接続することができるものであればよい。 The thickness of the connecting portion 30 is not particularly limited as long as it has elasticity and can connect the first fitting portion 10 and the second fitting portion 20.

次に、ビニールハウスを例に、シート止め具１の使用方法について説明する。図７は、シート止め具１を用いて、シート状部材であるビニールシート１００を支柱部材であるビニールハウスの骨組み１１０に固定した状態の概略図である。 Next, a method for using the sheet stopper 1 will be described using a greenhouse as an example. FIG. 7 is a schematic view of a state in which the vinyl sheet 100 that is a sheet-like member is fixed to the framework 110 of the greenhouse that is a support member using the sheet stopper 1.

この図に示すように、ビニールシート１００を挟んで、第１嵌着部１０の第１内周面１３と骨組み１１０とが嵌合すると共に、第２嵌着部２０の第２内周面２３と骨組み１１０とが嵌合することによって、シート状部材であるビニールシート１００が支柱部材であるビニールハウスの骨組み１１０に固定されることになる。 As shown in this figure, the first inner peripheral surface 13 of the first fitting portion 10 and the framework 110 are fitted with the vinyl sheet 100 interposed therebetween, and the second inner peripheral surface 23 of the second fitting portion 20 is fitted. By fitting the frame 110 with the frame 110, the vinyl sheet 100 that is a sheet-like member is fixed to the frame 110 of the greenhouse that is a support member.

そして、ビニールハウス内の空気と外気との入れ替えを行う際に次のような動作を行う。まず、骨組み１１０から第２嵌着部２０を取り外す。次に、ビニールシートをたくし上げ、そのたくし上げた部分（たくし上げシート部１０５）を連結部３０の凹部内に収容する。その後、図８に示すように、再度第２嵌着部２０を直接骨組み１１０に嵌着する。このようにシート止め具１を用いることによって、ビニールシートの一部をたくし上げた状態を保持することができる。 Then, the following operation is performed when the air in the greenhouse is replaced with the outside air. First, the second fitting portion 20 is removed from the skeleton 110. Next, the vinyl sheet is rolled up, and the raised portion (the rolled up sheet portion 105) is accommodated in the recess of the connecting portion 30. Thereafter, as shown in FIG. 8, the second fitting portion 20 is directly fitted to the framework 110 again. By using the sheet stopper 1 in this way, it is possible to maintain a state in which a part of the vinyl sheet is lifted.

なお、再度第２嵌着部２０を骨組み１１０から脱着させた後、ビニールシートのたくし上げた部分（たくし上げシート部１０５）を元の状態（単なるシート状）に戻した上で、ビニールシートを挟んで第２嵌着部２０を支柱部に嵌着させると、図７に示す状態に戻すことができる。 After the second fitting portion 20 is detached from the frame 110 again, the folded portion of the vinyl sheet (the raised sheet portion 105) is returned to the original state (simple sheet shape), and then the vinyl sheet is removed. If the 2nd fitting part 20 is made to fit in a support | pillar part on both sides, it can return to the state shown in FIG.

以上説明したようにシート止め具１を構成することによって、第２内周面２３の径が第１内周面１３の径よりも小さいので、第１嵌着部１０と比較して、第２嵌着部２０を骨組み１１０から容易に脱着させることができる。 By configuring the sheet stopper 1 as described above, the diameter of the second inner peripheral surface 23 is smaller than the diameter of the first inner peripheral surface 13. The fitting part 20 can be easily detached from the framework 110.

また、第２嵌着部２０の２つの摘み片２５を２つの摘み片２５が成す角の角度が小さくなる方向（内向き）に掴むことにより、第２開口部２２を容易に開口させることができるので、第２嵌着部２０を骨組みに容易に脱着させることができる。 Further, the second opening 22 can be easily opened by grasping the two knobs 25 of the second fitting part 20 in a direction (inward) in which the angle formed by the two knobs 25 is reduced. Since it can do, the 2nd fitting part 20 can be easily attached or detached to a framework.

さらに、連結部３０を有するので、ビニールシートをたくし上げた際に形成される、たくし上げシート部１０５を連結部３０の凹部に収容できる。その結果、第２嵌着部２０を骨組み１１０から取り外した後、シート状部材をたくし上げて、そのたくし上げシート部１０５を連結部３０の凹部に収容して第２嵌着部２０を骨組み１１０に嵌着させることができると共に、再度第２嵌着部を支柱部から脱着させた後、たくし上げシート部を元の状態（単なるシート状）に戻した上で、シート状部材を挟んで支柱部に再度嵌着させることができる。
（実施形態２） Further, since the connecting portion 30 is provided, the raised sheet portion 105 formed when the vinyl sheet is rolled up can be accommodated in the recess of the connecting portion 30. As a result, after the second fitting portion 20 is removed from the framework 110, the sheet-like member is lifted up, and the raised sheet portion 105 is accommodated in the concave portion of the connecting portion 30 so that the second fitting portion 20 is framed. After the second fitting part is detached from the support part again, the raised sheet part is returned to the original state (simple sheet form), and the support member is sandwiched between the sheet-like members. It can be fitted again to the part.

上述した実施形態では、連結部の形状は、半円弧状となっていたが、第１嵌着部の第１開口部や第２嵌着部の第２開口部に対して凹部を有するものであれば特に限定されない。連結部の形状としては、例えばコ字状、く字状、半円弧状を二つ連結した形状等が挙げられる。このような形状の連結部を用いても、上述した実施形態のシート止め具と同様の効果が得られる。
（実施形態３） In the embodiment described above, the shape of the connecting portion is a semicircular arc, but has a recess with respect to the first opening of the first fitting portion and the second opening of the second fitting portion. If there is no particular limitation. As a shape of a connection part, the shape etc. which connected two U shape, a square shape, and a semicircular arc shape etc. are mentioned, for example. Even if the connecting portion having such a shape is used, the same effect as that of the sheet stopper of the embodiment described above can be obtained.
(Embodiment 3)

上述した実施形態では、第１嵌着部の軸線方向の略中央部の外周面に、外周面に沿って突出する断面凹状の突部が形成され、その突部の凹部内に、金属製の剛性強化部が嵌合されていたが本発明はこれに限定されない。 In the embodiment described above, a protrusion having a concave cross-section protruding along the outer peripheral surface is formed on the outer peripheral surface of the substantially central portion in the axial direction of the first fitting portion, and a metal-made protrusion is formed in the concave portion of the protrusion. Although the rigidity reinforcing portion is fitted, the present invention is not limited to this.

例えば、断面凹状の突部の位置は特に限定されず、第１嵌着部の軸線方向の端部の外周面に設けられていてもよい。また、突部がなく、Ｕ字状の剛性強化部が直接第１嵌着部に嵌合されていてもよい。さらには、剛性強化部がなく、第１嵌着部の軸線方向の外周面に、外周面に沿って突出する断面凹状の突部が形成されていてもよい。 For example, the position of the protrusion having a concave cross section is not particularly limited, and may be provided on the outer peripheral surface of the end portion in the axial direction of the first fitting portion. Moreover, there is no protrusion and the U-shaped rigid reinforcement part may be directly fitted to the first fitting part. Furthermore, there is no rigidity reinforcing portion, and a protrusion having a concave cross section protruding along the outer peripheral surface may be formed on the outer peripheral surface in the axial direction of the first fitting portion.

このように第１嵌着部を構成しても、実施形態１の第１嵌着部よりも第１開口部の開口する方向に対する剛性は低くなるかもしれないが、実施形態１に係るシート止め具と同様の効果が得られる。
（実施形態４） Even if the first fitting portion is configured in this way, the rigidity in the opening direction of the first opening portion may be lower than that of the first fitting portion of the first embodiment. The same effect as the tool can be obtained.
(Embodiment 4)

実施形態１の２つの摘み片の対向する表面（内側表面）に、第２開口部の反対側方向に伸びる線状の凸部が３つ（両端部近傍に２つ、中央部に１つ）形成されていたが、本発明はこれに限定されない。線状の凸部の長さ、数、幅および高さは特に限定されない。なお、凸部が伸びる方向は、第１嵌着部または第２嵌着部の軸線方向と交差する方向であれば特に限定されない。 Three linear protrusions extending in the direction opposite to the second opening (two in the vicinity of both ends and one in the center) on the opposing surfaces (inner surfaces) of the two knobs of the first embodiment Although formed, the present invention is not limited to this. The length, number, width and height of the linear protrusion are not particularly limited. In addition, if the direction where a convex part is extended is a direction which cross | intersects the axial direction of a 1st fitting part or a 2nd fitting part, it will not specifically limit.

また、線状の凸部が設けられる場所も限定されない。例えば、２つの摘み片の対向する表面とは逆の表面（外側表面）に線状の凸部が形成されてもよい。このように線状の凸部を設けても、実施形態１のシート止め具と同様の効果が得られる。
（その他の実施形態） Moreover, the place where a linear convex part is provided is not limited. For example, linear protrusions may be formed on the surface (outer surface) opposite to the opposing surfaces of the two knobs. Thus, even if it provides a linear convex part, the effect similar to the sheet | seat fastener of Embodiment 1 is acquired.
