本発明は、地面中に埋設した受枠と蓋とをアームによっ
て開閉かつ反転自在に連結したマンホールに係るもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a manhole in which a receiving frame buried in the ground and a lid are connected by an arm so as to be openable, closable, and reversible.
従来、マンホールにおいては、地面中に受枠ン埋込み、

てもこれが跳上ることがある許りでなく。Traditionally, manholes have a receiving frame embedded in the ground,
A heavy dog lid is fitted into the receiving frame to close the manhole, but if the pressure inside the manhole rises abnormally for some reason, even if it is a heavy dog lid, it will jump up. I'm not allowed to do that.

おそれがあった。The lid could pivot and jump up, creating a risk of a dangerous situation.
本発明は上記の如き従来の実状に鑑み、受枠の内周面に
下方に従い縮径する下り傾斜面を形成し。In view of the above-mentioned conventional situation, the present invention forms a downwardly inclined surface whose diameter decreases downward on the inner circumferential surface of the receiving frame.

とができるマンホールケ提供しようとするものである。In a manhole in which an inclined surface matching the above-mentioned inclined surface is formed on the outer circumferential surface of the lid, a bracket V protrudes from the inner circumferential side of the receiving frame, and an arm is attached to the bracket. The lid is pivotally mounted to be movable up and down, and an engagement groove is formed on the dual surface of the lid, and the distal end engagement portion of the arm is slidably and rotatably engaged in the engagement groove; By connecting the lid to the receiving frame so that it can be opened, closed, and reversed,
The heavy electricity applied to the lid allows it to be placed on the slope of the lid receiving frame to maintain the lid closed.
Even if the pressure inside the manhole rises abnormally, it can prevent the lid from jumping up because it is connected to the receiving frame through the arm, and it can also prevent sliding and rotation even when the manhole is stoichiometric. It is an object of the present invention to provide a manhole holder in which the lid 7 can be easily opened by being guided by an existing arm, and the lid can also be easily closed when the manhole is closed.

閉かつ反転自在に連結されている。To explain one embodiment of the present invention shown in the drawings, reference numeral 1 denotes a receiving frame, the receiving frame 1 is buried in the ground, and its inner circumferential surface 2 is sloped downward so that its diameter decreases downward. formed on the surface. Reference numeral 3 denotes a lid, and the outer circumferential surface 4 of the metering 3 is an inclined surface that coincides with the downwardly inclined surface of the inner circumferential surface 2 of the receiving frame 1. Ribs 5 for reinforcement are formed on the back surface of the lid 3. Further, a bracket 6 is formed on the inner circumferential surface 2 of the receiving frame 1 on the negative side thereof, and an arm 7 is pivotally connected to the # bracket 6 by a pivot shaft 8 so as to be movable up and down. The tip of the arm 7 is a spherical tip retaining portion 9, and the tip engaging portion 9 of the arm 7 slides and rotates into an engagement concave 10 formed on the long surface of the lid 3. The arm 3 is connected to the receiving frame 1 via an arm 7 so as to be freely openable, closable, and reversible.

も多くの場合には善３が開くことはない。In a manhole configured like an upward slope, the outer peripheral surface of the closed lid 3 fits into the downwardly inclined surface of the receiving frame 1, and the more weight the lid 3 receives, the stronger the fitted state becomes. Therefore, the closed state can be maintained reliably. And the lid is closed! The first lid 3 is attached to the arm 7 on the receiving frame 1.
Since the lid 3 is connected through the manhole, even if the pressure inside the manhole increases abnormally, the lid 3 will not jump up, ensuring safety. If pressure is applied evenly to the entire surface of the pipe 3 connected via the arm 7, the engagement position of the end engagement portion 9 of the arm 7 with respect to the engagement recess @10 will not change, so that the inside of the manhole will not change. Even if the pressure increases abnormally, in many cases the good 3 will not open.
また、閉蓋時には、責３ンアームＩに案内させて開くこ
とができるので、蓋３の重量゛が犬であっても容易にそ
の作業ヶ行うことかできる。なお。In addition, when the lid 3 is closed, it can be opened by being guided by the handle arm I, so even if the lid 3 weighs as much as a dog, the operation can be done easily. In addition.
開いた蓋３はその裏面か上になるが、これン反転させて
表面ケ上にしておくこともできる。開いた看３ン閉じる
際にも、該蓋３はアーム７に案内されるので、その作業
も開蓋時と同時に容易である。When the lid 3 is opened, it will be on the back side or above, but it can also be turned over and left on the front side. Since the lid 3 is guided by the arm 7 even when the lid 3 is opened and closed, this operation is easy at the same time as opening the lid.

ある。In short, the present invention provides a manhole in which a downwardly inclined surface whose diameter decreases downwardly is formed on the inner circumferential surface of the receiving frame, and an elongated slope that coincides with the above-mentioned inclined surface is formed on the outer circumferential surface of the lid. 〇L11 has a bracket v protruding from it and an arm on the bracket? In addition to being pivotally mounted so as to be able to move up and down, an engagement groove is formed on the back surface of the lid, and the distal end engagement portion of the arm is slidably and rotatably engaged in the engagement groove, and the receiving frame is Since the lid is connected to the manhole so that it can be opened, closed, and reversed, the weight of the lid does not allow it to fit into the slope of the lid receiving frame and maintain a securely closed state, and the pressure inside the manhole is reduced. Even if the lid rises abnormally, it can be prevented from jumping up from the point where the lid is connected to the receiving frame via the arm, and it can be used inside a manhole, which is an extremely useful new effect case. It is something to play.
