Description
【考案の詳細な説明】
本考案は地下構造物用鉄蓋の固定構造に関するものであ
る。[Detailed Description of the Invention] The present invention relates to a fixing structure for iron covers for underground structures.
本考案の目的は蓋が不慮に飛出すことがなく、受枠内に
水平に納まる構造の地下構造物用鉄蓋を提供することに
ある。The object of the present invention is to provide an iron cover for underground structures which has a structure that prevents the cover from accidentally flying out and fits horizontally within the receiving frame.
しかして本考案は蓋１の下面周辺部にピン２により蝶番
金具３の上端を枢着し、該蝶番金具３は蓋１を受支する
受枠４に設けた突起５が係合する切欠６を形威し、蓋１
の閉鎖時切欠６を突起５に強制的に嵌めるための突子７
を蝶番金具３の上方において、該蝶番金具３或いは蓋１
の内面のいずれか一方に形威し、更に蝶番金具３を囲う
抜止環８を受枠４の内側に横方向に突出させた地下構造
物用鉄蓋の固定構造である。Therefore, in the present invention, the upper end of a hinge metal fitting 3 is pivotally attached to the peripheral part of the lower surface of the lid 1 by a pin 2, and the hinge metal fitting 3 has a notch 6 that engages with a protrusion 5 provided on a receiving frame 4 that supports the lid 1. Shape, lid 1
protrusion 7 for forcibly fitting the notch 6 into the protrusion 5 when the is closed;
above the hinge 3 or the lid 1.
This is a fixing structure for an iron cover for an underground structure in which a retaining ring 8 surrounding a hinge metal fitting 3 is formed on either one of the inner surfaces of the receiving frame 4 and projects laterally inside the receiving frame 4.
尚図示の蝶番金具３は自重で垂直になり、切欠６と突起
５とが一層係合し易くするため、抜は止めを兼ねた重り
９を下方に一体に突設すると同時に突起５を偏平状とし
、これに嵌合する切欠６も横長切欠とすることにより、
ピン２に対してより蓋１が前後左右に傾斜することを防
ぐようにしである。The illustrated hinge 3 becomes vertical under its own weight, and in order to make it easier for the notch 6 and the protrusion 5 to engage, a weight 9 that also serves as a stopper is integrally provided downward, and at the same time the protrusion 5 is flattened. By making the notch 6 that fits into this also a horizontally long notch,
This is to prevent the lid 1 from tilting forward, backward, left and right with respect to the pin 2.
又受枠４は蓋１の周縁に適合するよう嵌合縁４′を８度
前後傾斜させである。Further, the receiving frame 4 has a fitting edge 4' inclined at an angle of 8 degrees in order to fit the periphery of the lid 1.
そして第１図乃至第３図に示す例で突子７は蝶番金具３
に突設腰第４図の実施例は突子７を蓋１の内面に突出さ
せたものを示す。In the examples shown in FIGS. 1 to 3, the protrusion 7 is the hinge metal fitting 3.
In the embodiment shown in FIG. 4, the protrusion 7 is protruded from the inner surface of the lid 1.
更に突子７は後加工により寸法精度を出せば一層確実に
作用させることができる。Furthermore, if the protrusion 7 is post-processed to achieve dimensional accuracy, it can work more reliably.
本考案は以上説明した構成であるから、蓋１を受枠４に
載せて閉じると、その内面で抜止環８に挿入した蝶番金
具３或いは蓋１の内面の一方に突設した突子７を押すこ
とになるので、蝶番金具３の切欠６は必然的に突起５と
係合し、抜止環８による蝶番金具３の規制作用と相俟っ
て確実に蓋１を固定させることができる。Since the present invention has the configuration described above, when the lid 1 is placed on the receiving frame 4 and closed, the inner surface of the lid 1 pushes the hinge fitting 3 inserted into the retaining ring 8 or the protrusion 7 protruding from one of the inner surfaces of the lid 1. Therefore, the notch 6 of the hinge metal fitting 3 inevitably engages with the protrusion 5, and together with the restricting action of the hinge metal fitting 3 by the retaining ring 8, the lid 1 can be securely fixed.
