MANHOLE LOCK
PROBLEM TO BE SOLVED: To provide a manhole lock without requiring to execute cleaning work in key operation time on refuse and dust of depositing in an upward key groove for operating a cylinder provided on a surface of a manhole, without requiring to install a cover on the key groove, and also without requiring to replace the cylinder itself installed in a cover of the manhole when a key is lost.SOLUTION: A manhole lock comprises a key part 1 with the electric power supply function and a lock part 10 with the power receiving function for locking and unlocking by receiving electric power supply via an antenna from the key part 1 with the electric power supply function, and has no locking-unlocking key hole on the surface side of a manhole cover 15, and also has the function of transmitting-receiving individual discrimination (ID) for collation.SELECTED DRAWING: Figure 1
【課題】マンホールの表面に設けられたシリンダーを操作する上向きのキー溝に堆積するゴミや埃をキー操作時に清掃作業をする必要がなく、また、キー溝の上にカバーを装着することを必要とせず、キー紛失時に、マンホールの蓋に装着されているシリンダー自体を交換する必要もないマンホールロックを提供する。【解決手段】マンホールロックは、給電機能付きキー部１と、前記給電機能付きキー部１よりアンテナを介して給電を受けて施解錠を行う受電機能付きロック部１０とを有し、マンホール蓋１５の表面側に施解錠用鍵穴を有しない。また、照合するための個別識別（ＩＤ）の送受信を行う機能を有する。【選択図】図１
