ステー５Ａは、略長方形の板状をなし、略中間部が板厚方向でクランク状の形状をなしている。ステー５Ａは、一端部５ａが腕部３Ａの長尺部材Ｌ１の中間部のやや上の部位に当該長尺部材Ｌ１に回動自在に取り付けられ、他端部５ｂが腕部３Ｂの長尺部材Ｌ１の中間部のやや上の部位に当該長尺部材Ｌ１に対して着脱自在とされている。 The stay 5A has a substantially rectangular plate shape, and a substantially middle portion has a crank shape in the plate thickness direction. The stay 5A has one end 5a rotatably attached to the long member L1 at a position slightly above an intermediate portion of the long member L1 of the arm 3A, and the other end 5b is a long member of the arm 3B. A portion slightly above the intermediate portion of L1 is detachable from the long member L1.

すなわち、図３に示すように、腕部３Ａの長尺部材Ｌ１にはステー５Ａの一端部５ａに形成されている図示しない孔に挿通されて当該ステー５Ａの一端部５ａを回転自在に支持する回転支軸１１が形成されている。回転支軸１１は、ステー５Ａの一端部５ａが回転支軸１１の長さ方向に多少移動できるように、ステー５Ａの厚さよりも多少長くなっている。また、腕部３Ｂの長尺部材Ｌ１には係合凸部７が形成されている。係合凸部７は、所定の直径Ｄ１を有する円柱形状の脚部７１と、脚部７１の先端部に設けられ脚部７１よりも大きい直径Ｄ２を有する円盤形状の頭部７２とからなる。一方、ステー５Ａの他端部５ｂには、鍵穴形状の係合凹部（係合孔部）８が係合凸部７に係合しうるように形成されている。係合凹部８は、係合凸部７の頭部７２の直径Ｄ２以上の直径Ｄ３を有する略円形状の貫通孔８１と、貫通孔８１の周縁部（ステー５Ａの一端部５ａ側）に形成され幅Ｗ１が脚部７１の直径Ｄ１以上でかつ頭部７２の直径Ｄ２よりも小さい長方形状の係止溝８２とからなる。係止溝８２は、貫通孔８１の周縁部の上側部分からステー５Ａの一端部５ａ側に向かいステー５Ａの長辺方向と平行となるように延びている。 That is, as shown in FIG. 3, the long member L1 of the arm 3A is inserted into a hole (not shown) formed in the one end 5a of the stay 5A to rotatably support the one end 5a of the stay 5A. A rotation support shaft 11 is formed. The rotation support shaft 11 is slightly longer than the thickness of the stay 5A so that the one end 5a of the stay 5A can move slightly in the length direction of the rotation support shaft 11. Further, an engagement projection 7 is formed on the long member L1 of the arm 3B. The engaging projection 7 includes a column-shaped leg 71 having a predetermined diameter D1 and a disk-shaped head 72 provided at the tip of the leg 71 and having a diameter D2 larger than the leg 71. On the other hand, at the other end 5b of the stay 5A, a keyhole-shaped engaging concave portion (engaging hole portion) 8 is formed so as to be able to engage with the engaging convex portion 7. The engagement recess 8 is formed in a substantially circular through-hole 81 having a diameter D3 equal to or larger than the diameter D2 of the head 72 of the engagement protrusion 7 and a peripheral portion of the through-hole 81 (on one end 5a side of the stay 5A). And a rectangular locking groove 82 having a width W1 equal to or larger than the diameter D1 of the leg 71 and smaller than the diameter D2 of the head 72. The locking groove 82 extends from the upper part of the peripheral edge of the through hole 81 toward the one end 5a of the stay 5A so as to be parallel to the long side direction of the stay 5A.

ステー５Ｂも、ステー５Ａと同様な構成を有している。すなわち、ステー５Ｂは、略長方形の板状をなし、略中間部が板厚方向でクランク状の形状をなしている。そして、ステー５Ｂは、一端部５ａが腕部３Ａの長尺部材Ｌ２の中間部のやや上の部位に当該長尺部材Ｌ２に回動自在に取り付けられ、他端部５ｂが腕部３Ｂの長尺部材Ｌ２の中間部のやや上の部位に当該長尺部材Ｌ２に対して着脱自在とされている。 The stay 5B has the same configuration as the stay 5A. That is, the stay 5B has a substantially rectangular plate shape, and a substantially middle portion has a crank shape in the plate thickness direction. The stay 5B has one end 5a rotatably attached to the long member L2 at a position slightly above the middle of the long member L2 of the arm 3A, and the other end 5b has the length of the arm 3B. At a position slightly above the intermediate portion of the long member L2, it is detachable from the long member L2.

すなわち、図３に示すように、腕部３Ｂの長尺部材Ｌ２にはステー５Ｂの一端部５ａに形成されている図示しない孔に挿通されて当該ステー５Ｂの一端部５ａを回転自在に支持する回転支軸１１が形成されている。回転支軸１１は、ステー５Ｂの一端部５ａが回転支軸１１の長さ方向に多少移動できるように、ステー５Ｂの厚さよりも多少長くなっている。また、腕部３Ｂの長尺部材Ｌ２には係合凸部７が形成されている。係合凸部７は、所定の直径Ｄ１を有する円柱形状の脚部７１と、脚部７１の先端部に設けられ脚部７１よりも大きい直径Ｄ２を有する円盤形状の頭部７２とからなる。一方、ステー５Ｂの他端部５ｂには係合凹部８が係合凸部７に係合しうるように形成されている。係合凹部８は、係合凸部７の頭部７２の直径Ｄ２以上の直径Ｄ３を有する略円形状の貫通孔８１と、貫通孔８１の周縁部（ステー５Ｂの一端部５ａ側）に形成され幅Ｗ１が脚部７１の直径Ｄ１以上でかつ頭部７２の直径Ｄ２よりも小さい長方形状の係止溝８２とからなる。係止溝８２は、貫通孔８１の周縁部の上側部分からステー５Ａの一端部５ａ側に向かいステー５Ａの長辺方向と平行となるように延びている。 That is, as shown in FIG. 3, the long member L2 of the arm 3B is inserted through a hole (not shown) formed in the one end 5a of the stay 5B to rotatably support the one end 5a of the stay 5B. A rotation support shaft 11 is formed. The rotation support shaft 11 is slightly longer than the thickness of the stay 5B so that the one end 5a of the stay 5B can move slightly in the length direction of the rotation support shaft 11. Further, an engagement projection 7 is formed on the long member L2 of the arm 3B. The engaging projection 7 includes a column-shaped leg 71 having a predetermined diameter D1 and a disk-shaped head 72 provided at the tip of the leg 71 and having a diameter D2 larger than the leg 71. On the other hand, an engagement recess 8 is formed on the other end 5b of the stay 5B so as to be able to engage with the engagement protrusion 7. The engagement recess 8 is formed in a substantially circular through-hole 81 having a diameter D3 equal to or larger than the diameter D2 of the head 72 of the engagement protrusion 7 and a peripheral portion of the through-hole 81 (on one end 5a side of the stay 5B). And a rectangular locking groove 82 having a width W1 equal to or larger than the diameter D1 of the leg 71 and smaller than the diameter D2 of the head 72. The locking groove 82 extends from the upper part of the peripheral edge of the through hole 81 toward the one end 5a of the stay 5A so as to be parallel to the long side direction of the stay 5A.

そのため、運搬具１は、一対のステー５Ａ、５Ｂ及び腕部３Ａの一対の長尺部材Ｌ１、Ｌ２において、係合凸部７の頭部７２が係合凹部８の貫通孔８１に挿通されて、係合凸部７の脚部７１が係合凹部８の係止溝８２に嵌合したときには、図２（Ｂ）に示すように、ステー５Ａ、５Ｂの他端部５ｂが腕部３Ｂの長尺部材Ｌ１、Ｌ２から外れることを防止しつつ、ステー５Ａ、５Ｂが一対の載荷部４Ａ、４Ｂを水平方向に所定の距離Ｄ４だけ離間させた状態に維持する。 Therefore, in the carrier 1, in the pair of long members L1 and L2 of the pair of stays 5A and 5B and the arm 3A, the head 72 of the engaging convex portion 7 is inserted into the through hole 81 of the engaging concave portion 8. When the leg 71 of the engaging projection 7 is fitted into the locking groove 82 of the engaging recess 8, as shown in FIG. 2B, the other ends 5b of the stays 5A and 5B are connected to the arm 3B. The stays 5A and 5B keep the pair of loading portions 4A and 4B horizontally separated by a predetermined distance D4 while preventing the stays 5A and 5B from coming off the long members L1 and L2.

そして、図２（Ｂ）に示すように、運搬具１は、一対の載荷部４Ａ、４Ｂ上に建材６が架け渡されて水平に載置され、クレーンのフックＦによって建材６とともに吊り上げられるように構成されている。 Then, as shown in FIG. 2 (B), the transporting tool 1 is configured such that the building material 6 is hung over the pair of loading portions 4A and 4B and placed horizontally, and is lifted together with the building material 6 by the hook F of the crane.

先ず、作業者は、図２（Ａ）に示すように、一対のステー５Ａ、５Ｂの他端部５ｂが腕部３Ｂの長尺部材Ｌ１、Ｌ２から取り外され、一対の腕部３Ａ、３Ｂが閉じた状態から、図４（Ａ）に示すように、建材６の上方で、一対の腕部３Ａ、３Ｂを１８０°近くまで大きく開く。 First, as shown in FIG. 2A, the worker removes the other end 5b of the pair of stays 5A, 5B from the long members L1, L2 of the arm 3B, and removes the pair of arms 3A, 3B. From the closed state, as shown in FIG. 4A, the pair of arms 3A and 3B is greatly opened to approximately 180 ° above the building material 6.

次に、作業者は、図４（Ｂ）に示すように、運搬具１が建材６を包み込むように、運搬具１を降下させて、腕部３Ａ、３Ｂの下端部３ａをトラックの荷台１００に接触させる。その後、作業者は、運搬具１の腕部３Ａ、３Ｂの下端部３ａをトラックの荷台１００に接触させたまま、一対の腕部３Ａ、３Ｂを閉じる方向に所定の開度に達するまで操作する。すると、図４（Ｃ）に示すように、運搬具１は、一対の載荷部４Ａ、４Ｂが建材６の両端部近傍の裏面側に位置決めされる。このとき、一対の載荷部４Ａ、４Ｂは、建材６には接触せず、建材６の下方に少し離れて位置決めされている。 Next, as shown in FIG. 4 (B), the worker lowers the carrier 1 so that the carrier 1 wraps the building material 6 and moves the lower ends 3a of the arms 3A and 3B to the truck bed 100. Contact. Thereafter, the operator operates the pair of arms 3A and 3B in the closing direction until a predetermined degree of opening is reached, while keeping the lower ends 3a of the arms 3A and 3B of the carrier 1 in contact with the truck bed 100 of the truck. . Then, as shown in FIG. 4C, in the carrier 1, the pair of loading portions 4 A and 4 B are positioned on the back surface near both ends of the building material 6. At this time, the pair of loading portions 4A and 4B do not contact the building material 6 and are positioned slightly below the building material 6.

その後、作業者は、図２（Ｂ）に示すように、係合凹部８を係合凸部７に係合させることにより、一対のステー５Ａ、５Ｂの他端部５ｂを腕部３Ｂの長尺部材Ｌ１、Ｌ２に取り付ける。これにより、一対の載荷部４Ａ、４Ｂは、一対のステー５Ａ、５Ｂによって水平方向に所定の距離Ｄ４だけ離間させられた状態で固定される。 Thereafter, as shown in FIG. 2 (B), the worker engages the engaging concave portion 8 with the engaging convex portion 7, thereby connecting the other end 5b of the pair of stays 5A, 5B to the length of the arm 3B. Attached to the length members L1 and L2. As a result, the pair of loading portions 4A and 4B are fixed in a state where the pair of stays 5A and 5B are horizontally separated by the predetermined distance D4.

なお、回転支軸１１がステー５Ａ、５Ｂの厚さよりも多少長く、ステー５Ａ、５Ｂの一端部５ａが回転支軸１１の長さ方向に多少移動できるようになっている。これにより、ステー５Ａ、５Ｂの他端部５も腕部３Ｂの長尺部材Ｌ１、Ｌ２の係合凸部７の軸方向で移動できる余裕があるため、ステー５Ａ、５Ｂの他端部５を係合凸部７上（係合凸部の軸方向の上）に一旦浮かして、その後、係合凸部７を当該ステー５Ａ、５Ｂの他端部５に形成した係合凹部８に簡易に挿通させることができる。 Note that the rotation shaft 11 is slightly longer than the thickness of the stays 5A and 5B, and one end 5a of the stays 5A and 5B can move slightly in the longitudinal direction of the rotation shaft 11. This allows the other ends 5 of the stays 5A and 5B to move in the axial direction of the engagement projections 7 of the long members L1 and L2 of the arm 3B. Once floating on the engaging protrusions 7 (on the axial direction of the engaging protrusions), the engaging protrusions 7 are simply inserted into the engaging recesses 8 formed in the other end portions 5 of the stays 5A and 5B. Can be inserted.

その後、作業者は、図２（Ｂ）に示すように、取り付け部２の取り付け孔２２にクレーンのフックＦを引っ掛ける。この状態で、作業者は、クレーンを操作してフックＦ、すなわち、運搬具１を適宜上昇・下降させながら、当該運搬具１と建材６との位置関係を調整し、運搬具１の一対の載荷部４Ａ、４Ｂ上に建材６を水平に架け渡した状態にする。このとき、建材６は、各載荷部４Ａ、４Ｂのゴム部材４２、つまり、建材６との摩擦係数が大きい部材に接触して２点支持された状態で、２つの載荷面４１上にバランスよく安定して保持される。 Thereafter, the worker hooks the hook F of the crane in the mounting hole 22 of the mounting portion 2 as shown in FIG. In this state, the worker adjusts the positional relationship between the carrier 1 and the building material 6 while operating the crane to raise and lower the hook F, that is, the carrier 1 as appropriate. The building material 6 is placed horizontally on the loading units 4A and 4B. At this time, the building material 6 is well-balanced on the two loading surfaces 41 in a state where the building material 6 is in contact with the rubber members 42 of the loading portions 4A and 4B, that is, the members having a large friction coefficient with the building material 6 and supported at two points. It is kept stable.

それから、作業者は、クレーンを操作して、建材６を運搬具１に載せたままトラックの荷台１００から建材置き場まで運搬する。 Then, the worker operates the crane and transports the building material 6 from the truck bed 100 to the building material storage area with the building material 6 being placed on the carrier 1.

このとき、運搬具１は、当該運搬具１及び建材６がトラックの荷台１００から浮き上がることに伴って、一対の腕部３Ａ、３Ｂが自重及び建材６の重量で閉じようとする。そのため、腕部３Ｂの長尺部材Ｌ１、Ｌ２にそれぞれ形成された係合凸部７が各ステー５Ａ、５Ｂの一端部５ａ側へ移動し、係合凸部７の脚部７１が係合凹部８の係止溝８２に嵌合する。その結果、係合凸部７と係合凹部８とが強固に係合し、建材６の運搬中にわたって、一対の載荷部４Ａ、４Ｂが水平方向に離間した状態に維持され、ひいては、建材６の安定した運搬作業が継続される。 At this time, as the carrier 1 and the building material 6 are lifted from the bed 100 of the truck, the pair of arms 3A and 3B try to close by their own weight and the weight of the building material 6. Therefore, the engagement projections 7 formed on the long members L1 and L2 of the arm 3B move toward the one end 5a of each of the stays 5A and 5B, and the leg 71 of the engagement projection 7 engages with the engagement recess. 8 into the locking groove 82. As a result, the engaging projections 7 and the engaging recesses 8 are firmly engaged with each other, and during the transportation of the building material 6, the pair of loading portions 4A and 4B are kept horizontally separated from each other. Stable transport work is continued.

また、建材６は運搬具１上にバランスよく安定して保持されているので、たとえ建材６の運搬中に運搬具１が強風や地震で揺れたとしても、建材６を載荷部４Ａ、４Ｂから滑り落ちることなく安全かつ円滑に運搬できる。 Also, since the building material 6 is stably held on the carrier 1 in a well-balanced manner, even if the carrier 1 shakes due to a strong wind or an earthquake during the transportation of the building material 6, the building material 6 is moved from the loading portions 4A and 4B. It can be transported safely and smoothly without slipping down.

こうして、建材６をトラックの荷台１００から建材置き場まで運搬した後、作業者は、運搬具１を使用時の状態（図２（Ｂ）参照）から不使用時の状態（図２（Ａ）参照）に戻す。それには、クレーンのフックＦを取り付け部２の取り付け孔２２から取り外すとともに、係合凹部８と係合凸部７との係合状態を解除することにより、一対のステー５Ａ、５Ｂの他端部５ｂを腕部３Ｂの長尺部材Ｌ１、Ｌ２から取り外した後、一対の腕部３Ａ、３Ｂを大きく開き、建材６から運搬具１を取り外す。 In this way, after transporting the building material 6 from the truck bed 100 to the building material storage area, the worker changes the state of the carrier 1 from the state in use (see FIG. 2B) to the state in which it is not used (see FIG. 2A). ). To do so, the hook F of the crane is removed from the mounting hole 22 of the mounting portion 2 and the engagement between the engaging concave portion 8 and the engaging convex portion 7 is released, so that the other ends of the pair of stays 5A and 5B are removed. After removing 5b from the long members L1 and L2 of the arm 3B, the pair of arms 3A and 3B are widely opened, and the carrier 1 is removed from the building material 6.

すると、図２（Ａ）に示すように、運搬具１が折り畳まれてコンパクト化されるので、運搬具１をトラックの荷台１００に積んで建築現場から持ち帰るときに重宝する。同じ理由により、建材６の運搬作業に先立ち、運搬具１をトラックの荷台１００に積んで建築現場に持ち込むときにも重宝する。 Then, as shown in FIG. 2 (A), the carrier 1 is folded and compacted, which is useful when the carrier 1 is loaded on the truck bed 100 and brought back from the construction site. For the same reason, it is also useful to load the carrier 1 on the truck bed 100 and carry it to the construction site before carrying out the work of transporting the building material 6.

ここで、運搬具１による建材６の運搬作業が終了する。 Here, the operation of transporting the building material 6 by the transport device 1 ends.

なお、前記の説明では、建材６を運搬具１で運搬する際に、建材６の近傍に運搬具１をセットする作業（図４（Ａ）〜（Ｃ）参照）が終わってから、建材６をクレーンで運搬すべく、取り付け部２の取り付け孔２２にクレーンのフックＦを引っ掛けた。しかし、特に運搬具１が重い場合には、先に、取り付け部２の取り付け孔２２にクレーンのフックＦを引っ掛けてから、建材６の近傍に運搬具１をセットする作業を行ってもよい。この場合、運搬具１の重量をクレーンが負担するため、運搬具１が重くても建材６の一連の運搬作業を容易かつ円滑に進められる。 In the above description, when the building material 6 is carried by the carrier 1, after the work of setting the carrier 1 near the building material 6 (see FIGS. 4A to 4C), The hook F of the crane was hooked on the mounting hole 22 of the mounting portion 2 in order to transport the. However, especially when the carrier 1 is heavy, the work of setting the carrier 1 near the building material 6 after first hooking the hook F of the crane in the mounting hole 22 of the mounting portion 2 may be performed. In this case, since the crane bears the weight of the carrier 1, a series of operations for transporting the building material 6 can be easily and smoothly performed even if the carrier 1 is heavy.

（第１の実施形態における効果）
（１）運搬具１は、取り付け部２と、一対の腕部３Ａ、３Ｂと、一対の載荷部４Ａ、４Ｂと、一対のステー５Ａ、５Ｂとからなる簡単な構造であり、クレーンのフックＦで建材６を容易に吊り上げて運搬できる。 (Effects in First Embodiment)
(1) The carrier 1 has a simple structure including a mounting portion 2, a pair of arms 3A and 3B, a pair of loading portions 4A and 4B, and a pair of stays 5A and 5B. Thus, the building material 6 can be easily lifted and transported.

（２）運搬具１は、一対の腕部３Ａ、３Ｂが互いに回動自在とされており、一対のステー５Ａ、５Ｂが一対の腕部３Ａ、３Ｂに対して着脱自在であるため、一対の腕部３Ａ、３Ｂから一対のステー５Ａ、５Ｂを取り外し、一対の腕部３Ａ、３Ｂを閉じることにより、コンパクト化できる。その結果、運搬具１を持ち運ぶときの利便性が向上する。 (2) In the carrier 1, the pair of arms 3A and 3B are rotatable relative to each other, and the pair of stays 5A and 5B are detachable from the pair of arms 3A and 3B. By removing the pair of stays 5A and 5B from the arms 3A and 3B and closing the pair of arms 3A and 3B, the size can be reduced. As a result, convenience when carrying the carrier 1 is improved.

（３）運搬具１は、各腕部３Ａ、３Ｂがそれぞれ、互いに平行な一対の長尺部材Ｌ１、Ｌ２から構成され、各載荷部４Ａ、４Ｂがそれぞれ各腕部３Ａ、３Ｂの一対の長尺部材Ｌ１、Ｌ２間に水平に架け渡されているため、建材６を一対の載荷部４Ａ、４Ｂにバランスよく架け渡して運搬できる。 (3) In the carrier 1, each arm 3A, 3B is composed of a pair of long members L1, L2 parallel to each other, and each of the loading parts 4A, 4B is paired with each of the arms 3A, 3B. Since the building material 6 is horizontally hung between the length members L1 and L2, the building material 6 can be hung and carried on the pair of loading portions 4A and 4B with good balance.

（４）運搬具１は、一対の腕部３Ａ、３Ｂが、互いに回動自在とされており、各ステー５Ａ、５Ｂは、一端部５ａが一方の腕部３Ａに回動自在に取り付けられ、他端部５ｂが他方の腕部３Ｂに着脱自在になっているため、不使用時にコンパクト化できるとともに、使用時に簡単に組み立てられる。 (4) The carrier 1 has a pair of arms 3A and 3B rotatable with respect to each other, and each of the stays 5A and 5B has one end 5a rotatably attached to one arm 3A. Since the other end 5b is detachable from the other arm 3B, it can be made compact when not in use and easily assembled when used.

（５）運搬具１は、腕部３Ｂに係合凸部７が形成され、ステー５Ａ、５Ｂに係合凹部８が係合凸部７に係合しうるように形成されている。さらに、係合凸部７は、脚部７１と頭部７２とからなり、係合凹部８は、貫通孔８１と係止溝８２とからなる。そのため、運搬具１は、使用時において、係合凹部８を係合凸部７に係合させることにより、簡単に組み立てられ、さらに、係合凸部７の脚部７１が係合凹部８の係止溝８２に嵌合することにより、係合凸部７と係合凹部８とが強固に係合する。 (5) The carrier 1 is formed such that the engagement projection 7 is formed on the arm 3B, and the engagement recess 8 can be engaged with the engagement projection 7 on the stays 5A and 5B. Further, the engaging projection 7 includes a leg 71 and a head 72, and the engaging recess 8 includes a through hole 81 and a locking groove 82. Therefore, the carrier 1 can be easily assembled by engaging the engaging concave portion 8 with the engaging convex portion 7 in use, and further, the leg 71 of the engaging convex portion 7 By fitting into the locking groove 82, the engaging projection 7 and the engaging recess 8 are firmly engaged.

（６）運搬具１は、各載荷部４Ａ、４Ｂの載荷面４１にそれぞれゴム部材４２が付設されているため、建材６が運搬中に載荷部４Ａ、４Ｂから滑り落ちる危険を防止できる。 (6) Since the rubber member 42 is attached to the loading surface 41 of each of the loading portions 4A and 4B, the building tool 6 can be prevented from slipping off the loading portions 4A and 4B during transportation.

なお、本実施形態では、クレーンのフックＦは、例えば、吊り上げ手段を構成する。 In the present embodiment, the hook F of the crane constitutes, for example, a lifting unit.

（第２の実施形態）
次に、第２の実施形態を説明する。第２の実施形態でも、運搬具を挙げている。 (Second embodiment)
Next, a second embodiment will be described. The second embodiment also describes a vehicle.

図５は、第２の実施形態に係る運搬具のステーを示す正面図である。図６は、運搬具の使用時の状態を示す側面図である。 FIG. 5 is a front view showing a stay of the carrier according to the second embodiment. FIG. 6 is a side view showing a state when the carrier is used.

（構成）
第２の実施形態では、運搬具１は、種々の曲げ剛性をもつ建材６に幅広く対応できるように、一対のステー５Ａ、５Ｂの係合凹部８の形状が、前述の第１の実施形態と異なっている。具体的には、図５に示すように、運搬具１の各ステー５Ａ、５Ｂの係合凹部８は、それぞれ、係合凸部７の頭部７２の直径Ｄ２以上の直径Ｄ３を有する略円形状の貫通孔８１と、貫通孔８１の周縁部２箇所（ステー５Ａ、５Ｂの一端部５ａ側及び他端部５ｂ側）にそれぞれ形成され幅Ｗ１が脚部７１の直径Ｄ１以上でかつ頭部７２の直径Ｄ２よりも小さい２つの長方形状の係止溝８２、８３とからなる。ここで、係止溝８２は、前述の第１の実施形態と同様に、貫通孔８１の周縁部の上側部分からステー５Ａの一端部５ａ側に向かいステー５Ａの長辺方向と平行となるように延びている。一方、係止溝８３は、貫通孔８１の周縁部の上側部分からステー５Ａの他端に向かいステー５Ａの長辺方向と平行となるように延びている。第２の実施形態では、このように、係合凹部８は、全体として略Ｔ字形状をなしている。 (Constitution)
In the second embodiment, the shape of the engagement recesses 8 of the pair of stays 5A and 5B is different from that of the first embodiment described above so that the carrier 1 can widely support building materials 6 having various bending stiffness. Is different. Specifically, as shown in FIG. 5, the engagement recesses 8 of the stays 5A and 5B of the carrier 1 each have a substantially circular shape having a diameter D3 equal to or larger than the diameter D2 of the head 72 of the engagement protrusion 7. Shaped through hole 81 and two peripheral portions of the through hole 81 (one end 5a side and the other end 5b side of the stays 5A and 5B), each having a width W1 greater than or equal to the diameter D1 of the leg 71 and the head. 72, two rectangular locking grooves 82 and 83 smaller than the diameter D2. Here, similarly to the first embodiment, the locking groove 82 is parallel to the long side direction of the stay 5A from the upper side of the peripheral portion of the through hole 81 toward the one end 5a of the stay 5A. Extends. On the other hand, the locking groove 83 extends from the upper part of the peripheral portion of the through hole 81 to the other end of the stay 5A so as to be parallel to the long side direction of the stay 5A. In the second embodiment, as described above, the engaging recess 8 has a substantially T-shape as a whole.

その他の構成については、前述の第１の実施形態と同様であるため、同一の部材に同一の符号を付してその説明を省略する。 The other configuration is the same as that of the above-described first embodiment. Therefore, the same members are denoted by the same reference numerals, and description thereof will be omitted.

（動作、作用等）
運搬具１の動作、及びその作用等については、前述の第１の実施形態とほぼ同様である。ただし、運搬具１で運搬する建材６の曲げ剛性が小さい場合には、図６に示すように、運搬中の建材６のたわみ量が大きくなり、運搬具１の係合凸部７と係合凹部８との係合状態が異なる可能性がある。 (Movement, action, etc.)
The operation of the carrier 1 and the operation thereof are substantially the same as in the first embodiment. However, when the bending stiffness of the building material 6 transported by the carrier 1 is small, the amount of deflection of the building material 6 during transportation increases as shown in FIG. The engagement state with the recess 8 may be different.

すなわち、建材６の曲げ剛性が所定の数値より大きい場合には、建材６を運搬具１に載せても建材６がほとんどたわまないため（図２（Ｂ）参照）、建材６から運搬具１の一対の載荷部４Ａ、４Ｂに作用して一対の腕部３Ａ、３Ｂを開こうとする力の水平成分（以下、外向き水平分力という。）が、運搬具１の一対の腕部３Ａ、３Ｂが自重や建材６の重量で閉じようとする力の水平成分（以下、内向き水平分力という。）より小さく、結果的に載荷部４Ａ、４Ｂが互いに近づく向きＰ１に移動して、一対の腕部３Ａ、３Ｂが閉じようとする。そのため、運搬具１は、第１の実施形態と同様、係合凸部７の脚部７１が係合凹部８の一方（ステー５Ａ、５Ｂの一端部５ａ側）の係止溝８２に嵌合する。その結果、係合凸部７と係合凹部８とが強固に係合し、建材６の運搬中にわたって、一対の載荷部４Ａ、４Ｂが水平方向に離間した状態に維持され、ひいては、建材６の安定した運搬作業が継続される。 That is, when the bending stiffness of the building material 6 is larger than the predetermined value, the building material 6 hardly bends even if the building material 6 is placed on the carrier 1 (see FIG. 2B). A horizontal component (hereinafter, referred to as an outward horizontal component force) of a force acting on the pair of loading portions 4A and 4B to open the pair of arms 3A and 3B is generated by a pair of arms of the carrier 1. 3A and 3B are smaller than the horizontal component (hereinafter referred to as an inward horizontal component force) of the force that attempts to close with their own weight or the weight of the building material 6, and as a result, the loading portions 4A and 4B move in the direction P1 approaching each other. , The pair of arms 3A, 3B are about to close. Therefore, in the carrier 1, similarly to the first embodiment, the leg 71 of the engaging projection 7 is fitted into the locking groove 82 of one of the engaging recesses 8 (the end 5 a side of the stays 5 A and 5 B). I do. As a result, the engaging projections 7 and the engaging recesses 8 are firmly engaged with each other, and during the transportation of the building material 6, the pair of loading portions 4A and 4B are kept horizontally separated from each other. Stable transport work is continued.

これに対して、建材６の曲げ剛性が所定の数値より小さい場合には、図６に示すように、建材６を運搬具１に載せたときに、建材６が自重で大きく湾曲するようにたわむ。すると、外向き水平分力が内向き水平分力より大きくなり、結果的に載荷部４Ａ、４Ｂが互いに遠ざかる向きＰ２に移動して、一対の腕部３Ａ、３Ｂが開こうとする。そのため、運搬具１は、係合凸部７の脚部７１が係合凹部８の他方（ステー５Ａ、５Ｂの他端部５ｂ側）の係止溝８３に嵌合する。その結果、係合凸部７と係合凹部８とが強固に係合し、建材６の運搬中にわたって、一対の載荷部４Ａ、４Ｂが水平方向に離間した状態に維持され、ひいては、建材６の安定した運搬作業が継続される。 On the other hand, when the bending stiffness of the building material 6 is smaller than the predetermined value, as shown in FIG. 6, when the building material 6 is placed on the vehicle 1, the building material 6 bends so as to be largely bent by its own weight. . Then, the outward horizontal component becomes larger than the inward horizontal component, and as a result, the loading portions 4A and 4B move in the direction P2 away from each other, and the pair of arms 3A and 3B try to open. Therefore, in the carrier 1, the leg 71 of the engaging protrusion 7 is fitted into the locking groove 83 on the other side of the engaging recess 8 (the other end 5 b side of the stays 5 A and 5 B). As a result, the engaging projections 7 and the engaging recesses 8 are firmly engaged with each other, and during the transportation of the building material 6, the pair of loading portions 4A and 4B are kept horizontally separated from each other. Stable transport work is continued.

したがって、いずれの場合でも、運搬具１で運搬する建材６の種類（曲げ剛性の大小）を問わず、運搬具１による建材６の運搬作業は、トラックの荷台１００から建材置き場まで安定して行われる。 Therefore, in any case, regardless of the type (bending rigidity) of the building material 6 carried by the carrier 1, the carrying operation of the building material 6 by the carrier 1 is performed stably from the truck bed 100 to the building material storage area. Is

（第２の実施形態における効果）
運搬具１の効果については、前述の第１の実施形態と同様である。 (Effects in Second Embodiment)
The effect of the carrier 1 is the same as that of the first embodiment.

なお、本実施形態でも、クレーンのフックＦは、例えば、吊り上げ手段を構成する。 Note that, also in the present embodiment, the hook F of the crane constitutes, for example, a lifting unit.

（第３の実施形態）
次に、第３の実施形態を説明する。第３の実施形態でも、運搬具を挙げている。 (Third embodiment)
Next, a third embodiment will be described. The third embodiment also exemplifies a carrier.

図７は、第３の実施形態に係る運搬具の側面図であって、（Ａ）は不使用時の状態図、（Ｂ）は使用時の状態図である。 7A and 7B are side views of the carrier according to the third embodiment, in which FIG. 7A is a state diagram when not in use, and FIG. 7B is a state diagram when in use.

（構成）
第３の実施形態では、係合凸部７と係合凹部８との係合・解除によって腕部３Ｂの一対の長尺部材Ｌ１、Ｌ２と一対のステー５Ａ、５Ｂとを固定・解除する方式（第１及び第２の実施形態）に代えて、一対のステー５Ａ、５Ｂを中折れ固定構造にすることにより、一対の腕部３Ａ、３Ｂを開閉自在とする方式を採用している。 (Constitution)
In the third embodiment, a method in which the pair of long members L1 and L2 of the arm 3B and the pair of stays 5A and 5B are fixed and released by engaging and releasing the engagement convex portion 7 and the engagement concave portion 8, respectively. Instead of the first and second embodiments, a method is adopted in which the pair of arms 3A, 3B can be freely opened and closed by forming a pair of stays 5A, 5B into a center-bend fixing structure.

ここで、ステー５Ａ、５Ｂの中折れ固定構造とは、ステー５Ａ、５Ｂの長さ方向の中央部に設けられた中折れ点５ｃを中心として両側の直線部材５ｄ、５ｅが互いに約０°〜１８０°の角度範囲内で回動自在になっており、しかも、ステー５Ａ、５Ｂの中折れ点５ｃの両側の直線部材５ｄ、５ｅが１８０°開いてステー５Ａ、５Ｂが一直線状に伸びた状態で固定できる構造を意味する。 Here, the middle bend fixing structure of the stays 5A and 5B means that the straight members 5d and 5e on both sides of the stays 5A and 5B are about 0 ° to each other with a center bend point 5c provided at the center in the longitudinal direction of the stays 5A and 5B. A state in which the linear members 5d and 5e on both sides of the middle break point 5c of the stays 5A and 5B are opened by 180 ° so that the stays 5A and 5B extend linearly within an angle range of 180 °. Means a structure that can be fixed.

すなわち、図７に示すように、運搬具１は、鉄板製のステー５Ａが中折れ固定構造になっており、ステー５Ａの一端部５ａが腕部３Ａの長尺部材Ｌ１に回動自在に連結され、ステー５Ａの他端部５ｂが腕部３Ｂの長尺部材Ｌ１に回動自在に連結されている。また、鉄板製のステー５Ｂが中折れ固定構造になっており、ステー５Ｂの一端部５ａが腕部３Ａの長尺部材Ｌ２に回動自在に連結され、ステー５Ｂの他端部５ｂが腕部３Ｂの長尺部材Ｌ２に回動自在に連結されている。 That is, as shown in FIG. 7, the carrier 1 has a stay 5A made of an iron plate in a bent-in and fixed structure, and one end 5a of the stay 5A is rotatably connected to the long member L1 of the arm 3A. The other end 5b of the stay 5A is rotatably connected to the long member L1 of the arm 3B. Further, a stay 5B made of an iron plate has a bent and fixed structure, one end 5a of the stay 5B is rotatably connected to the long member L2 of the arm 3A, and the other end 5b of the stay 5B is connected to the arm. 3B is rotatably connected to the long member L2.

合板、角材などの建材６を建築現場に搬入するに際して、建材６を積んだトラックの荷台１００からクレーン（例えば、当該トラックのクレーン）で建材６を吊り上げて所定の建材置き場まで運搬するときには、作業者は、先ず、トラックの荷台１００で、運搬具１を不使用時の状態（図７（Ａ）参照）から使用時の状態（図７（Ｂ）参照）にする。 When transporting building materials 6 such as plywood and square timber to a building site, when the building materials 6 are lifted from a bed 100 of a truck on which the building materials 6 are loaded by a crane (for example, the crane of the truck) and transported to a predetermined building material storage area, work is performed. First, the user changes the state of the carrier 1 from a non-use state (see FIG. 7A) to a use state (see FIG. 7B) on the truck bed 100.

それには、作業者は、図７（Ａ）に示すように、一対のステー５Ａ、５Ｂが中折れ状態であるとともに、一対の腕部３Ａ、３Ｂが閉じた状態で、図７（Ｂ）に示すように、一対の腕部３Ａ、３Ｂを所定の角度に開く。すると、一対のステー５Ａ、５Ｂは、一端部５ａ及び他端部５ｂが互いに遠ざかる向きＰ３に引っ張られる形で、中折れ点５ｃの両側の直線部材５ｄ、５ｅが開いていく。そして、中折れ点５ｃの両側の直線部材５ｄ、５ｅが１８０°開いたところで、ステー５Ａ、５Ｂは、一直線状に伸びた状態で固定される。これにより、一対の載荷部４Ａ、４Ｂは、一対のステー５Ａ、５Ｂによって離間させられた状態になる。 For this purpose, as shown in FIG. 7 (A), the worker moves the state shown in FIG. 7 (B) with the pair of stays 5A, 5B in a folded state and the pair of arms 3A, 3B closed. As shown, the pair of arms 3A and 3B are opened at a predetermined angle. Then, in the pair of stays 5A and 5B, the linear members 5d and 5e on both sides of the center folding point 5c are opened in such a manner that the one end 5a and the other end 5b are pulled in the direction P3 away from each other. Then, when the linear members 5d and 5e on both sides of the center folding point 5c are opened by 180 °, the stays 5A and 5B are fixed in a state of extending straight. Thus, the pair of loading portions 4A and 4B are separated from each other by the pair of stays 5A and 5B.

次に、作業者は、図７（Ｂ）に示すように、運搬具１の前後方向（図７（Ｂ）左右方向）から、取り付け部２と腕部３Ａ、３Ｂと載荷部４Ａ、４Ｂとで包囲された空間に建材６を差し込み、一対の載荷部４Ａ、４Ｂに建材６を架け渡して水平に載せる。すると、建材６は、各載荷部４Ａ、４Ｂのゴム部材４２、つまり、建材６との摩擦係数が大きい部材に接触して２点支持された状態で、２つの載荷面４１上にバランスよく安定して保持される。 Next, as shown in FIG. 7 (B), the worker, from the front-back direction of the carrier 1 (the left-right direction in FIG. 7 (B)), attaches the mounting portion 2, the arms 3A, 3B, and the loading portions 4A, 4B. The building material 6 is inserted into the space surrounded by and the building material 6 is hung over the pair of loading portions 4A and 4B and placed horizontally. Then, the building material 6 is stably and well-balanced on the two loading surfaces 41 in a state where the building material 6 is in contact with the rubber members 42 of the loading portions 4A and 4B, that is, the members having a large friction coefficient with the building material 6 and supported at two points. Will be held.

さらに、作業者は、図７（Ｂ）に示すように、取り付け部２の取り付け孔２２にクレーンのフックＦを引っ掛ける。この状態で、作業者は、クレーンを操作してフックＦを適宜上昇・下降させることにより、建材６を運搬具１に載せたままトラックの荷台１００から建材置き場まで運搬する。 Further, the worker hooks the hook F of the crane in the mounting hole 22 of the mounting portion 2 as shown in FIG. In this state, the operator operates the crane to appropriately raise and lower the hook F, thereby transporting the building material 6 from the truck bed 100 to the building material storage place while keeping the building material 6 on the carrier 1.

このとき、運搬具１は、当該運搬具１及び建材６がトラックの荷台１００から浮き上がることに伴って、一対の腕部３Ａ、３Ｂが自重及び建材６の重量で閉じようとする。しかし、運搬具１は、ステー５Ａ、５Ｂが中折れ固定構造になっており、ステー５Ａ、５Ｂが一直線状に伸びた状態で固定されるので、建材６の運搬中にわたって、一対の載荷部４Ａ、４Ｂが水平方向に離間した状態に維持され、ひいては、建材６の安定した運搬作業が継続される。 At this time, as the carrier 1 and the building material 6 are lifted from the bed 100 of the truck, the pair of arms 3A and 3B try to close by their own weight and the weight of the building material 6. However, since the stays 5A and 5B are fixed in a state where the stays 5A and 5B are stretched in a straight line, the carrier 1 has a pair of loading portions 4A while the building material 6 is being transported. , 4B are maintained in a horizontally separated state, and the stable work of transporting the building material 6 is continued.

こうして、建材６をトラックの荷台１００から建材置き場まで運搬した後、作業者は、運搬具１を使用時の状態から不使用時の状態に戻す。それには、作業者は、一対のステー５Ａ、５Ｂの中折れ点５ｃを押し上げつつ、一対の腕部３Ａ、３Ｂを閉じる。すると、一対のステー５Ａ、５Ｂは、一端部５ａ及び他端部５ｂが互いに近づく向きＰ４に押される形で、中折れ点５ｃの両側の直線部材５ｄ、５ｅが閉じていく。そして、中折れ点５ｃの両側の直線部材５ｄ、５ｅがほぼ０°に閉じると、一対の腕部３Ａ、３Ｂが完全に閉じた状態（不使用時の状態）になる。 In this way, after transporting the building material 6 from the truck bed 100 to the building material storage area, the operator returns the carrier 1 from the state of use to the state of non-use. To do so, the operator closes the pair of arms 3A, 3B while pushing up the middle break point 5c of the pair of stays 5A, 5B. Then, the pair of stays 5A and 5B are pushed in the direction P4 in which the one end 5a and the other end 5b approach each other, and the linear members 5d and 5e on both sides of the center folding point 5c are closed. Then, when the linear members 5d and 5e on both sides of the middle folding point 5c are closed to almost 0 °, the pair of arms 3A and 3B is completely closed (state when not in use).

（第３の実施形態における効果）
（１）運搬具１は、取り付け部２と、一対の腕部３Ａ、３Ｂと、一対の載荷部４Ａ、４Ｂと、一対のステー５Ａ、５Ｂといった少ない点数の構造からなり、簡単な構造であり、クレーンのフックＦで建材６を容易に吊り上げて運搬できる。 (Effect in Third Embodiment)
(1) The carrier 1 has a simple structure including a small number of structures such as an attachment portion 2, a pair of arms 3A and 3B, a pair of loading portions 4A and 4B, and a pair of stays 5A and 5B. The building material 6 can be easily lifted and transported by the hook F of the crane.

（２）運搬具１は、開閉自在の一対の腕部３Ａ、３Ｂが中折れ固定構造の一対のステー５Ａ、５Ｂで連結されているため、一対のステー５Ａ、５Ｂを中折れ状態にして一対の腕部３Ａ、３Ｂを閉じることにより、コンパクト化できる。その結果、運搬具１を持ち運ぶときの利便性が向上する。 (2) Since the pair of arms 3A and 3B that can be freely opened and closed is connected by a pair of stays 5A and 5B having a fixed structure, the carrier 1 has a pair of stays 5A and 5B that are folded in the middle. By closing the arms 3A and 3B, the size can be reduced. As a result, convenience when carrying the carrier 1 is improved.

（４）運搬具１は、一対の腕部３Ａ、３Ｂが、互いに回動自在とされており、各ステー５Ａ、５Ｂは、それぞれ中折れ固定構造になっているため、不使用時にコンパクト化できるとともに、使用時に簡単に組み立てられる。 (4) The carrier 1 has a pair of arms 3A and 3B that are rotatable relative to each other, and each of the stays 5A and 5B has a center-bend fixing structure. With it, it can be easily assembled at the time of use.

（５）運搬具１は、各載荷部４Ａ、４Ｂの載荷面４１にそれぞれゴム部材４２が付設されているため、建材６が運搬中に載荷部４Ａ、４Ｂから滑り落ちる危険を防止できる。 (5) Since the rubber member 42 is attached to the loading surface 41 of each of the loading sections 4A and 4B, the building tool 6 can be prevented from slipping off the loading sections 4A and 4B during transportation.

（本実施形態の変形例等）
前記の実施形態の他の例として、第１及び第２の実施形態において、係合凸部７と係合凹部８との形成部位を入れ替えた運搬具（図示せず）を挙げることもできる。すなわち、この運搬具では、腕部３Ｂの長尺部材Ｌ１、Ｌ２にそれぞれ係合凹部８が形成され、ステー５Ａ、５Ｂの他端部５ｂにそれぞれ係合凸部７が形成されている。この場合も、第１及び第２の実施形態と同様、係合凹部８を係合凸部７に係合させることにより、一対の載荷部４Ａ、４Ｂを一対のステー５Ａ、５Ｂによって離間させることができ、使用時に運搬具を簡単に組み立てられるという効果を奏する。 (Modifications of the present embodiment, etc.)
As another example of the above-described embodiment, a carrier (not shown) in which the formation portions of the engagement protrusions 7 and the engagement recesses 8 are replaced in the first and second embodiments may be mentioned. That is, in this carrier, the engaging concave portions 8 are formed in the long members L1 and L2 of the arm portion 3B, and the engaging convex portions 7 are formed in the other end portions 5b of the stays 5A and 5B. Also in this case, as in the first and second embodiments, the pair of loading portions 4A and 4B are separated from each other by the pair of stays 5A and 5B by engaging the engaging concave portion 8 with the engaging convex portion 7. Therefore, there is an effect that the carrier can be easily assembled at the time of use.

また、前記の実施形態の他の例として、第１及び第２の実施形態において、係合凸部７及び係合凹部８の構成部品は種々の形状に変更可能である。すなわち、係合凸部７の脚部７１の形状は、円柱形状に限定されず他の柱形状、例えば、多角柱形状としてもよい。係合凸部７の頭部７２の形状は、円柱形状に限定されず他の形状、例えば、半球形状としてもよい。係合凹部８の貫通孔８１の形状は、円形状に限定されず他の形状、例えば、楕円形状としてもよい。係合凹部８の係止溝８２、８３の形状は、長方形状に限定されず他の形状、例えば、Ｕ字形状としてもよい。 Further, as another example of the above-described embodiment, in the first and second embodiments, the components of the engagement protrusion 7 and the engagement recess 8 can be changed to various shapes. That is, the shape of the leg 71 of the engaging projection 7 is not limited to the column shape, and may be another column shape, for example, a polygonal column shape. The shape of the head 72 of the engaging projection 7 is not limited to a columnar shape, but may be another shape, for example, a hemispherical shape. The shape of the through-hole 81 of the engagement recess 8 is not limited to a circular shape, but may be another shape, for example, an elliptical shape. The shape of the locking grooves 82 and 83 of the engaging recess 8 is not limited to a rectangular shape, but may be another shape, for example, a U-shape.

また、前記の実施形態の他の例として、第１及び第２の実施形態において、一対の腕部３Ａ、３Ｂを長手方向に伸縮自在としてもよい。それには、例えば、腕部３Ａ、３Ｂを構成する長尺部材Ｌ１、Ｌ２として、直径の異なる２本の鉄パイプを互いに軸心方向に摺動して挿通自在とし、各鉄パイプの周面にそれぞれ、鉄パイプの軸心方向に沿って複数個の貫通孔を鉄パイプの軸心方向に直角な方向に形成し、２本の鉄パイプを串刺しするように、貫通孔に止め付けピンを通して２本の鉄パイプを互いに固定する構造を有し、止め付けピンを通す貫通孔を変えることによって全長が変わるものを用いる方法が考えられる。 Further, as another example of the above-described embodiment, in the first and second embodiments, the pair of arms 3A and 3B may be made extendable and contractible in the longitudinal direction. To this end, for example, as long members L1 and L2 constituting the arms 3A and 3B, two iron pipes having different diameters are slidable in the axial direction with respect to each other so as to be freely inserted, and the peripheral surface of each iron pipe is formed. In each case, a plurality of through holes are formed in the direction perpendicular to the axial direction of the iron pipe along the axial direction of the iron pipe, and two through holes are inserted through the through holes so as to skew the two iron pipes. A method using a structure having a structure in which the iron pipes are fixed to each other and having a different overall length by changing the through hole through which the fixing pin passes is conceivable.

この場合、運搬具１は、一対の腕部３Ａ、３Ｂを伸ばすことにより、一対の載荷部４Ａ、４Ｂ間の距離Ｄ４を長くできる。そのため、図４（Ａ）〜（Ｃ）に示すように、一対の載荷部４Ａ、４Ｂ上に建材６を載置するときに、建材６の長さＤ５が長くても、一対の載荷部４Ａ、４Ｂ上に建材６を支障なく載荷できる。 In this case, the carrier 1 can extend the distance D4 between the pair of loading sections 4A and 4B by extending the pair of arms 3A and 3B. Therefore, as shown in FIGS. 4A to 4C, when the building material 6 is placed on the pair of loading portions 4A and 4B, even if the length D5 of the building material 6 is long, the pair of loading portions 4A And the building material 6 can be loaded on the 4B without any trouble.

さらに、運搬具１は、腕部３Ａ、３Ｂを伸縮させることにより、建材６のサイズ（長さ）に応じて、建材６を支持する一対の載荷部４Ａ、４Ｂ間の距離Ｄ４を適宜調整できる。そのため、運搬具１で建材６を運搬する際に、建材６の長さＤ５が長くても短くても、一対の載荷部４Ａ、４Ｂ上に建材６を安定して載荷できるので、運搬具１の汎用性が高くなる。 Further, the carrier 1 can appropriately adjust the distance D4 between the pair of loading portions 4A and 4B supporting the building material 6 according to the size (length) of the building material 6 by expanding and contracting the arms 3A and 3B. . Therefore, when transporting the building material 6 with the carrier 1, the building material 6 can be stably loaded on the pair of loading portions 4A and 4B regardless of whether the length D5 of the building material 6 is long or short. Versatility is increased.

また、前記の実施形態の他の例として、第１及び第２の実施形態において、第３の実施形態で開示した手法（図７参照）によって運搬具１に建材６を載荷してもよい。 Further, as another example of the above embodiment, in the first and second embodiments, the building material 6 may be loaded on the carrier 1 by the method disclosed in the third embodiment (see FIG. 7).

また、前記の実施形態の他の例として、第３の実施形態において、一対の腕部３Ａ、３Ｂを長手方向に伸縮自在としてもよい。腕部３Ａ、３Ｂを長手方向に伸縮自在とする一法としては、前述の方法が考えられる。 Further, as another example of the above-described embodiment, in the third embodiment, the pair of arms 3A and 3B may be configured to be extendable and contractible in the longitudinal direction. As one method of making the arms 3A and 3B extendable in the longitudinal direction, the above-described method is considered.

この場合、運搬具１は、腕部３Ａ、３Ｂを伸縮させることにより、建材６のサイズ（長さ）に応じて、建材６を支持する一対の載荷部４Ａ、４Ｂ間の距離Ｄ４を適宜調整できる。そのため、運搬具１で建材６を運搬する際に、建材６の長さＤ５が長くても短くても、一対の載荷部４Ａ、４Ｂ上に建材６を安定して載荷できるので、運搬具１の汎用性が高くなる。 In this case, the carrier 1 adjusts the distance D4 between the pair of loading portions 4A and 4B supporting the building material 6 according to the size (length) of the building material 6 by expanding and contracting the arms 3A and 3B. it can. Therefore, when transporting the building material 6 with the carrier 1, the building material 6 can be stably loaded on the pair of loading portions 4A and 4B regardless of whether the length D5 of the building material 6 is long or short. Versatility is increased.

また、前記の実施形態の他の例として、取り付け部２の材料は、鉄板に限定されず他の材料、例えば、鉄板と鉄丸棒とを溶接した複合材料としてもよい。 Further, as another example of the above-described embodiment, the material of the mounting portion 2 is not limited to the iron plate, and may be another material, for example, a composite material obtained by welding an iron plate and an iron round bar.

また、前記の実施形態の他の例として、長尺部材Ｌ１、Ｌ２、Ｌ３、Ｌ４の材料は、鉄パイプに限定されず他の材料、例えば、鉄丸棒としてもよい。 Further, as another example of the above embodiment, the material of the long members L1, L2, L3, L4 is not limited to the iron pipe, and may be another material, for example, an iron round bar.

また、前記の実施形態の他の例として、一対のステー５Ａ、５Ｂの材料は、鉄板に限定されず他の材料、例えば、鋼板としてもよい。 Further, as another example of the above-described embodiment, the material of the pair of stays 5A and 5B is not limited to the iron plate, and may be another material, for example, a steel plate.

また、前記の実施形態の他の例として、運搬対象は、建材６に限定されず他の運搬対象、例えば、土木資材、撮影機材、楽器としてもよい。 Further, as another example of the above-described embodiment, the transport target is not limited to the building material 6 and may be another transport target, for example, civil engineering materials, photographing equipment, or musical instruments.

また、前記の実施形態の他の例として、ゴム部材４２に代えてシリコーン樹脂などの摩擦係数が大きい部材を載荷面４１に付設することも可能である。或いは、載荷面４１に凹凸を付与することにより、建材６との摩擦係数を高めてもよい。 Further, as another example of the above-described embodiment, a member having a large friction coefficient such as a silicone resin may be attached to the loading surface 41 instead of the rubber member 42. Alternatively, the coefficient of friction with the building material 6 may be increased by providing the loading surface 41 with irregularities.

さらに、前記の各変形例を適宜組み合わせてもよい。例えば、取り付け部２の材料として、鉄板と鉄丸棒とを溶接した複合材料を採用するとともに、運搬対象を建材６以外のものとしても構わない。 Further, the above-described modifications may be appropriately combined. For example, as the material of the mounting portion 2, a composite material in which an iron plate and an iron round bar are welded may be employed, and the object to be transported may be other than the building material 6.
