LATCH HANDLE DEVICE
PROBLEM TO BE SOLVED: To provide a latch handle device capable of drawing a door close to a casing side when locking the door being in a closed state.SOLUTION: In a latch handle device, a pair of long holes 22 extending in a fore-and-aft direction are provided in a latch incorporating recession 21 of a case 14 built in a door 3, at opposing positions on the peripheral walls of the recession, and both ends of a fulcrum shaft 23 are slidably inserted into the long holes 22. Further, centering the fulcrum shaft 23, a handle 24 and a latch 28 having a hook part 29 capable of engaging/disengaging with a latch receiving tool 5 attached around an opening of a casing 1, at a tip end, are swingably provided, where the latch 28 is biased toward an engagement direction by an elastic member 32. Cam levers 25 are also provided on one side of a swing center side of the handle 24. Then, in a state of the latch 28 being engaged with the latch receiving tool 5, the handle 24 is swung toward a locking position, and rollers 27 on tip ends of the cam levers 25 are rolled along a bottom wall of the recession 21 to make the rollers 27 be pressed against the bottom wall. By the pressing, the door 3 is pushed in toward the casing 1 side and presses a packing 4 provided around the opening of the casing 1, thereby sealability between the door and the packing is secured.SELECTED DRAWING: Figure 3
【課題】閉鎖状態とした扉の施錠時に、その扉を筐体側に引き寄せることができるようにしたラッチハンドル装置を提供することである。【解決手段】扉３に組み込まれるケース１４のラッチ組込み用凹部２１の周壁対向位置に一対の前後方向に長い長孔２２を設け、その長孔２２内に支点軸２３の両端部をスライド自在に挿入する。支点軸２３を中心にしてハンドル２４と、筐体１の開口部周囲に取り付けられたラッチ受け具５に対して係脱可能な鉤部２９を先端に有するラッチ２８とを揺動自在に設け、ラッチ２８を弾性部材３２により係合方向に向けて付勢する。ハンドル２４の揺動中心側の一側部にカムレバー２５を設け、ラッチ２８がラッチ受け具５に係合する状態で、ハンドル２４を施錠位置に向けて揺動し、カムレバー２５の先端のローラ２７を凹部２１の底壁に沿って転がり移動して、そのローラ２７が底壁を押圧し、その押圧により扉３を筐体１側に押し込み、筐体１の開口部周囲に設けられたパッキン４を扉３で押圧してシール性を確保する。【選択図】図３
