GATE DOOR LOCK DEVICE

PROBLEM TO BE SOLVED: To propose a gate door lock device for making it possible to recognize whether or not a gate door is locked at first glance even from the inside or outside of the gate door and even from a position somewhat apart from the gate door, without viewing a lock lever.SOLUTION: A gate door lock device of the present invention (for example, a lock device 3 as described below) rotatably fixed to a support on the door end side (for example, a support pillar 4 on the door end side as described below) at a height of the upper end of a gate door body (for example, a gate door body 2 as described below) includes: a recess (for example, a recess 32 as described below) with which the door end side of the upper end of the gate door body is to be engaged from above; and two knob and regulation members (for example, knob and regulation members 33 as described below) on both side faces of the lock device, the knob and regulation members protruding horizontally.SELECTED DRAWING: Figure 1 【課題】ロックレバーを目視せずに、門扉の内側からも外側からも、さらに門扉から多少離れた位置からでも一目で門扉がロックされているかどうかがわかる門扉用のロック装置を提案する。【解決手段】本発明の門扉用のロック装置（例えば、後述のロック装置３）は、戸先側の支持体（例えば、後述の戸先側の支柱４）に、門扉本体（例えば、後述の門扉本体２）の上端部の高さに回動自在に固定され、門扉本体の上端部の戸先側を上から係合させるための凹部（例えば、後述の凹部３２）と、ロック装置の両側面にあり水平に突出した２つのつまみ兼規制部材（例えば、後述のつまみ兼用規制部材３３）と、を有することを特徴とする。【選択図】図１
