LATCH DEVICE OF OPERATION HANDLE FOR OPENING/CLOSING CARGO BOX DOOR OF TRUCK
PROBLEM TO BE SOLVED: To provide a latch device of an operation handle for a cargo box door in which rainwater and muddy water hardly infiltrate in a rotation mechanism part of a lock and a stopper, and an operation failure hardly occurs.SOLUTION: A latch device 1 includes: a fixing body 2 fixed at a front surface of a door D; a hook lever 3 pivotally supported in a lever receiving opening 11 in a freely raised manner; a dead point spring mechanism 4 for rotationally energizing it in a falling direction or a standing direction; and a lock 5 and a stopper 6 for constraining and locking the hook lever 3 at a falling position. In a housing part 7, a water shielding wall 14 is formed for separating the rear part of the lock 5 and the stopper 6 from the lever receiving opening 11 at the upper part. By the water shielding wall 14, muddy water and the like infiltrating into the housing part 7 from the lever receiving opening 11 is stopped from infiltrating in the rear part of the lock 5 and the stopper 6.
【課題】雨水や泥水が錠前やストッパーの回転機構部に浸入しにくく、動作不良を生じにくい荷箱用扉の操作ハンドルの掛金装置を提供する。【解決手段】掛金装置１は、扉Ｄの前面に固着される固定本体２と、それのレバー受け開口１１内に起伏自在に枢支されるフックレバー３と、これを倒伏方向または起立方向に回転付勢するデッドポイントばね機構４と、フックレバー３を倒伏位置で拘束、錠止する錠前５及びストッパー６とを具備する。ハウジング部７内には、錠前５の後部とストッパー６をその上方においてレバー受け開口１１から隔てる遮水壁１４が形成される。遮水壁１４によって、レバー受け開口１１からハウジング部７内に浸入した泥水等が錠前５の後部とストッパー６へ浸入するのが阻止される。【選択図】図３
