従来、この種構造は、円形の蓋体外周を一部突設、又は凹欠し、これと対応す る受枠を合わせる構成、更に、蓋体と受枠を蝶番で連結し、回り止めとする構成 がある。 Conventionally, this kind of structure has a structure in which the outer circumference of a circular lid is partially protruded or recessed, and a receiving frame corresponding to this is fitted, and further, a configuration in which the lid and the receiving frame are connected by a hinge to prevent rotation. There is.
【０００３】[0003]
本考案が目的とする要点は、円形鉄蓋に於て、構成する蓋体と受枠が相対的に 回って、ずれない構成とするものであり、更に、車両通過に伴う騒音の発生を防 ぐため、該蓋体と受枠の接触部を機械加工することが通例であるが、この旋盤加 工に於て、突起物の存在は障害となる。本考案は、その回り止め構造を旋盤加工 の範囲から離した部位に構成するものであり、更に、該回り止め構造を利用して 、蓋体の跳びはねを防止する構成とすることを解決すべき技術的課題とするもの である。 The main purpose of the present invention is to construct a circular iron lid so that the lid body and the receiving frame rotate relative to each other so that they do not shift, and furthermore, the generation of noise accompanying vehicle passage is prevented. Therefore, it is customary to machine the contact portion between the lid and the receiving frame, but the presence of the protrusions becomes an obstacle in this lathe processing. According to the present invention, the detent structure is constructed at a position separated from the range of the lathe processing, and further, the detent structure is used to prevent the lid from splashing. This is a technical issue to be addressed.

上記課題を解決するための技術的手段は、円形鉄蓋に於て、開口部を有する受 枠の開口部の周縁に、上面より見て、Ｕ字状凹部を有する突起を構成し、該Ｕ字 状凹部と対応する、開閉する蓋体の裏面に直立する棒状突起を構成するものであ り、更に、該棒状突起の先端を充分伸ばし、該部分にストッパーとしての張り出 しを有する構成とする。 The technical means for solving the above-mentioned problems is, in a circular iron lid, a projection having a U-shaped concave portion when viewed from above is formed at the periphery of the opening of the receiving frame having the opening. A rod-shaped projection that corresponds to the letter-shaped recess and stands upright on the back surface of the lid that opens and closes. Further, the tip of the rod-shaped projection is sufficiently extended, and a protrusion as a stopper is provided at this portion. To do.

【作用】 上記構成とすることにより、受枠開口部周縁に突設したＵ字状凹部に対して、 蓋体裏面に直立する棒状突起を係合する事により相対的な旋回を止めるものであ り、更に、該棒状突起の先端に張り出しを設ける事により、こねがＵ字状凹部に 引掛り、蓋体の跳びはねを防止するものである。[Advantages] With the above configuration, the relative turning is stopped by engaging the U-shaped recess projecting on the peripheral edge of the receiving frame opening with the rod-shaped projection standing upright on the back surface of the lid. Further, by providing an overhang at the tip of the rod-shaped projection, the kneading is caught in the U-shaped recess and the jumping of the lid is prevented.

以下に、本考案の実施例を図面に基ずいて説明する。図１、図２に於て、１は 受枠、２はその開口部、３はＵ字状凹部４を有する突設部、５は開閉する蓋体、 ６は該蓋体５の裏面に直立する棒状突起を示すものであり、次に、図３、図４に 於て、７は前記棒状突起６を伸ばし、且つ其の先端にストッパーとしての張り出 し８を有する回り止め兼用ロック部を示し、図１状態に於て、棒状突起６がＵ字 状凹部４に係合して蓋体５が回り止め状態となるものであり、図３状態に於て、 回り止め兼用ロック部７がＵ字状凹部４に係合、且つその下縁に張り出し８が引 掛り、回り止め状態であると共に跳びはねの防止状態となるものである。 Embodiments of the present invention will be described below with reference to the drawings. In FIGS. 1 and 2, 1 is a receiving frame, 2 is an opening thereof, 3 is a projecting portion having a U-shaped concave portion, 5 is a lid that opens and closes, and 6 is upright on the back surface of the lid 5. Next, in FIGS. 3 and 4, reference numeral 7 designates a bar-shaped projection, and 7 designates the bar-shaped projection 6 extending and also having a protrusion 8 as a stopper at the tip thereof, which also serves as a detent lock. In the state shown in FIG. 1, the rod-shaped projection 6 engages with the U-shaped concave portion 4 so that the lid body 5 is in the rotation preventing state, and in the state shown in FIG. The protrusion 8 is engaged with the character-shaped concave portion 4 and the lower edge of the protrusion 8 is hooked to prevent rotation and prevent jumping.

以上の如く本考案によれば、地中管路を管理するための流路方向を表示した円 形鉄蓋の場合、蓋体が車両通過によって旋回するのを防ぎ、又、同じく車両通過 によって蓋体が跳び跳ねるのを防止するものであり、更に、騒音防止のため、及 び受枠と蓋体の隙間を少なくするため、それぞれの対接面を旋盤加工するに際し て、加工面に突起物がなく、容易に製作することが出来るとゆう効果がある。 As described above, according to the present invention, in the case of the circular iron lid that displays the flow direction for controlling the underground pipeline, the lid body is prevented from turning due to the passage of the vehicle, and the lid is also closed by the passage of the vehicle. It prevents the body from jumping and bouncing.In addition, in order to prevent noise and to reduce the gap between the receiving frame and the lid, when lathe-processing each contact surface, protrusions are not formed on the machined surface. There is a good effect that it can be easily manufactured.
