蓋開閉治具1は、一方向に延びるハンドル部11と、ハンドル部11の一端側に設けられて大蓋被嵌合部2bと嵌合する大蓋用嵌合部としての大蓋嵌合部12と、大蓋嵌合部12の内側に設けられて小蓋被嵌合部3bと嵌合する小蓋用嵌合部としての小蓋嵌合部13とを備えている。蓋開閉治具1は、金属製で、各部材が接合されて一体的に構成されている。ハンドル部11の一端側には、円形板状のベース部14が設けられ、大蓋嵌合部12及び小蓋嵌合部13はベース部14の同一の面に設けられている。   The lid opening / closing jig 1 includes a handle portion 11 extending in one direction, and a large lid fitting portion provided on one end side of the handle portion 11 and serving as a large lid fitting portion that is fitted to the large lid fitted portion 2b. 12 and a small lid fitting portion 13 as a small lid fitting portion that is provided inside the large lid fitting portion 12 and is fitted to the small lid fitted portion 3b. The lid opening / closing jig 1 is made of metal and integrally formed by joining the members. A circular plate-like base portion 14 is provided on one end side of the handle portion 11, and the large lid fitting portion 12 and the small lid fitting portion 13 are provided on the same surface of the base portion 14.

大蓋嵌合部12は、大蓋2のねじ溝2aの内側に挿入可能な円筒部12aと、円筒部12aの端部の二箇所に設けられる切欠き12bとを有する。切欠き12bは、円筒部12aの端部を半円形に切り取って形成されている。切欠き12bは、大蓋被嵌合部2bの2つの被嵌合部としての凸部2cに対応して設けられている。凸部2cは、大蓋2の内周面に互いに向かい合うようにして設けられている。切欠き12bの側面が凸部2cの側面と接触して回転力を付与することで大蓋2を開閉する。小蓋嵌合部13は、突起部13aを有する。一方の小蓋被嵌合部3bは、コの字型の部材の中央部分が小蓋3の内側底面と固定されており、これにより形成された被嵌合部としての溝3cに突起部13aが嵌め合い可能に形成される。突起部13aは、その両側が二面取りされた直線状の突起で、溝3cに嵌め合わせて回転させることで小蓋3を開閉する。   The large lid fitting portion 12 includes a cylindrical portion 12a that can be inserted inside the screw groove 2a of the large lid 2, and cutouts 12b that are provided at two locations on the end of the cylindrical portion 12a. The notch 12b is formed by cutting the end of the cylindrical portion 12a into a semicircular shape. The notch 12b is provided corresponding to the convex part 2c as two to-be-fitted parts of the large lid to-be-fitted part 2b. The convex portions 2 c are provided on the inner peripheral surface of the large lid 2 so as to face each other. The large lid 2 is opened and closed by the side surface of the notch 12b coming into contact with the side surface of the convex portion 2c and applying a rotational force. The small lid fitting portion 13 has a protruding portion 13a. One small lid fitted portion 3b has a central portion of a U-shaped member fixed to the inner bottom surface of the small lid 3, and a projection 13a is formed in a groove 3c formed as a fitted portion. Are formed so that they can be fitted together. The protrusion 13a is a straight protrusion having two chamfered sides, and is fitted in the groove 3c and rotated to open and close the small lid 3.

小蓋嵌合部13の突起部13aは、大蓋嵌合部12の円筒部12aの内側に位置する。このため、ベース部14に対して突出した突起部13aを円筒部12aが取り囲むことにより、突起部13aを円筒部12aが保護する役割も有している。図2に蓋開閉治具1の要部の側面図を示す。突起部13aの上端部としての上部13bは、円筒部12aの上端部としての上部12cよりも高さhの分だけ突出している。なお、突起部13aは、六角形状の部材を二面取りすることで形成され、さらに円形状の部材を介してベース部14と連結されている。六角形状の部材だと二面取りの加工時に固定が容易で、加工しやすいためである。   The protrusion 13 a of the small lid fitting portion 13 is located inside the cylindrical portion 12 a of the large lid fitting portion 12. For this reason, when the cylindrical part 12a surrounds the projection part 13a which protruded with respect to the base part 14, the cylindrical part 12a also has a role which protects the projection part 13a. FIG. 2 shows a side view of the main part of the lid opening / closing jig 1. The upper portion 13b as the upper end portion of the protruding portion 13a protrudes by the height h from the upper portion 12c as the upper end portion of the cylindrical portion 12a. The protrusion 13a is formed by chamfering a hexagonal member, and is further connected to the base portion 14 via a circular member. This is because a hexagonal member is easy to fix and easy to process during two-chamfer processing.

蓋開閉治具1の作用を説明する。ドラム缶Dに対して大蓋2を取り外し、あるいは取り付ける場合には、円筒部12aを大蓋2に挿入し、大蓋被嵌合部2bの凸部2cと切欠き12bとを嵌め合わせ、ベース部14を中心にハンドル部11を回動あるいは回転させることで大蓋2を開閉する。小蓋3の場合には、突起部13aを小蓋3の溝3cに嵌め合わせ、大蓋2と同様にハンドル部11を操作することにより開閉できる。小蓋2の開閉の際に、円筒部12aが小蓋3の外側に位置することになるが、突起部13aの上部13bが円筒部12aの上部12cよりも突出しているので、円筒部12aがドラム缶Dに接触することなく小蓋3の開閉が可能である。従って、ドラム缶Dを傷付けることなく小蓋3を開閉できる。また、ベース部14の一方の面に各嵌合部12、13が設けられているので、作業者は蓋開閉治具1を持ち替えることなく蓋開閉作業を行うことができ、効率的である。   The operation of the lid opening / closing jig 1 will be described. When removing or attaching the large lid 2 to the drum can D, the cylindrical portion 12a is inserted into the large lid 2, and the convex portion 2c of the large lid fitted portion 2b and the notch 12b are fitted together to form the base portion. The large lid 2 is opened and closed by rotating or rotating the handle portion 11 around 14. In the case of the small lid 3, the protrusion 13 a can be fitted into the groove 3 c of the small lid 3 and can be opened and closed by operating the handle portion 11 in the same manner as the large lid 2. When the small lid 2 is opened and closed, the cylindrical portion 12a is positioned outside the small lid 3, but since the upper portion 13b of the protruding portion 13a protrudes from the upper portion 12c of the cylindrical portion 12a, the cylindrical portion 12a is The small lid 3 can be opened and closed without contacting the drum can D. Therefore, the small lid 3 can be opened and closed without damaging the drum D. Moreover, since each fitting part 12 and 13 is provided in one surface of the base part 14, the operator can perform a lid | cover opening / closing operation | work, without changing the lid | cover opening / closing jig 1, and it is efficient.

本発明は、上述した形態に限定されることなく、種々の形態にて実施することができる。例えば、本形態では、ハンドル部11の形状を一方向に延びる棒状として説明したが、これに限られず、T字状等各種の形状で構成してもよい。また、切欠き12bの形状を半円形状として説明したが、これに限られず、各種形状に形成してよい。適宜の形状としても凸部2cと噛み合えば大蓋2を開閉することができる。大蓋被嵌合部2bと切欠き12bとの嵌合、及び小蓋被嵌合部3bと突起部13aとの嵌合は、それぞれ遊びがあってもよい。互いに引っ掛けることができれば蓋開閉治具1は大蓋2及び小蓋3を開閉することができる。突起部13aの形状についても直線状に限られず、小蓋被嵌合部3bの形状に応じて適宜変更してよい。   The present invention is not limited to the above-described form and can be implemented in various forms. For example, in the present embodiment, the shape of the handle portion 11 has been described as a rod shape extending in one direction. Moreover, although the shape of the notch 12b has been described as a semicircular shape, it is not limited to this, and may be formed in various shapes. The large lid 2 can be opened and closed as long as it is meshed with the convex portion 2c. There may be play in the fitting between the large lid fitted portion 2b and the notch 12b and the fitting between the small lid fitted portion 3b and the protruding portion 13a. If they can be hooked together, the lid opening / closing jig 1 can open and close the large lid 2 and the small lid 3.
