建物や冷蔵庫本体等の固定枠体側の受け金２２にフックボルト３１の先端フッ ク部が係合した施錠状態では、フックボルト３１の受動突起３８が内側レバーハ ンドル２９の駆動突起３６に当接している。また、錠前ユニット３の止め金板１ ８は外側レバーハンドル８の錠止突起１４に当接し、連動レバー１０の受動突起 １７は外側レバーハンドル８の駆動突起１５に当接している。 Attach the end hook of the hook bolt 31 to the receiver 22 on the fixed frame side of a building or refrigerator body. In the locked state where the hook part is engaged, the passive protrusion 38 of the hook bolt 31 is The drive protrusion 36 of the handle 29 is in contact with the drive protrusion 36 of the handle 29 . In addition, the stop plate 1 of the lock unit 3 8 is in contact with the locking protrusion 14 of the outer lever handle 8, and the passive protrusion of the interlocking lever 10. 17 is in contact with the drive protrusion 15 of the outer lever handle 8.
【０００９】 錠前ユニット３に適合する鍵を挿入してロータ１９を図５において時計回り方 向に回すと、止め金板１８による外側レバーハンドル８の拘束が解除される。バ ネ２５の付勢に抗して外側レバーハンドル８を軸孔６を中心に時計回り方向に鎖 線位置まで回転させると、外側レバーハンドル８の駆動突起１５が連動レバー１ ０の受動突起１７を押すため、連動レバー１０がバネ２１の付勢に抗して鎖線位 置まで回転する。[0009] Insert the compatible key into the lock unit 3 and turn the rotor 19 clockwise in Fig. 5. When turned in the opposite direction, the restraint of the outer lever handle 8 by the stop plate 18 is released. Ba Chain the outer lever handle 8 clockwise around the shaft hole 6 against the bias of the screw 25. When rotated to the line position, the drive protrusion 15 of the outer lever handle 8 engages the interlocking lever 1. 0, the interlocking lever 10 resists the bias of the spring 21 and moves to the chain line position. Rotate to the position.
【００１０】 この連動レバー１０の回転は外側軸棒７と連動角棒４５と内側軸棒２８を介し てフックボルト３１に伝えられ、フックボルト３１が図６において軸孔２７を中 心にして時計回り方向に一体的に回転する。フックボルト３１が鎖線位置まで回 転すると、先端フック部が受け金２２から離脱するため、固定枠体に対する引き 戸４７の錠止が解除される。0010 The rotation of the interlocking lever 10 is performed via the outer shaft rod 7, the interlocking square rod 45, and the inner shaft rod 28. is transmitted to the hook bolt 31, and the hook bolt 31 passes through the shaft hole 27 in FIG. Rotate as one in a clockwise direction. Hook bolt 31 is rotated to the chain line position. When the tip is rotated, the tip hook part separates from the holder 22, so there is no pull on the fixed frame. Door 47 is unlocked.
【００１１】 このようにして解錠された引き戸４７は、外側レバーハンドル８に掛けた手を 更に横に引くことによって開放操作される。引き戸４７の開放後、外側レバーハ ンドル８から手を離すと、外側レバーハンドル８とフックボルト３１はバネ２５ 、３９の付勢によって元の位置に復帰する。引き戸４７を閉鎖方向に直線移動さ せた時、閉鎖の終端においてフックボルト３１の先端部の円弧カム面４８に受け 金２２が当接する。そのため、フックボルト３１は軸孔２７を中心に一旦退避回 転する。[0011] The sliding door 47 unlocked in this way can be opened with the hand placed on the outside lever handle 8. It can be opened by pulling it further to the side. After opening the sliding door 47, release the outer lever. When you release your hand from the handle 8, the outer lever handle 8 and the hook bolt 31 are released by the spring 25. , 39 returns to the original position. Move the sliding door 47 straight in the closing direction. When the hook bolt 31 is closed, it is received by the arcuate cam surface 48 at the tip of the hook bolt 31. Gold 22 comes into contact. Therefore, the hook bolt 31 is temporarily retracted around the shaft hole 27. Turn around.
【００１２】 引き戸４７が完全に閉鎖された時、フックボルト３１は若干角度逆回転し、フ ックボルト３１の先端部と受け金２２が自動的に係合する。閉鎖後、錠前ユニッ ト３のロータ１９を施錠位置に回し、止め金板１８を外側レバーハンドル８の錠 止突起１４に係合させる。0012 When the sliding door 47 is completely closed, the hook bolt 31 rotates slightly in the opposite direction and the door opens. The tip of the lock bolt 31 and the receiver 22 automatically engage with each other. After closing, lock unit Rotate the rotor 19 of the outer lever handle 8 to the lock position, and lock the stop plate 18 of the outer lever handle 8. It is engaged with the stop projection 14.
【００１３】 冷蔵庫等の固定本体の内部に作業員が残っているにもかかわらず、錠前ユニッ ト３によって外側レバーハンドル８が施錠位置に拘束されてしまったときには、 当該作業員はバネ４１の付勢に抗して内側レバーハンドル２９を図６において軸 孔２７を中心に時計回り方向に鎖線位置まで回転させれば良い。[0013] Even though a worker remains inside a fixed body such as a refrigerator, the lock unit When the outer lever handle 8 is restrained in the locked position by the grip 3, The worker pivots the inner lever handle 29 in FIG. 6 against the bias of the spring 41. It is sufficient to rotate it clockwise around the hole 27 to the position indicated by the chain line.
【００１４】 この操作により、内側レバーハンドル２９の駆動突起３６がフックボルト３１ の受動突起３８を押すため、フックボルト３１がバネ３９の付勢に抗して鎖線位 置まで回転する。かくして、フックボルト３１の先端フック部が受け金２２から 離脱するため、固定枠体に対する引き戸４７の錠止が解除される。[0014] By this operation, the drive protrusion 36 of the inner lever handle 29 is moved to the hook bolt 31. In order to push the passive protrusion 38, the hook bolt 31 resists the bias of the spring 39 and moves to the chain line position. Rotate to the position. In this way, the tip hook portion of the hook bolt 31 is removed from the receiving plate 22. In order to separate, the sliding door 47 is unlocked from the fixed frame.
【００１５】 このフックボルト３１の回転は内側軸棒２８と連動角棒４５と外側軸棒７を介 してフックボルト３１に伝えられ、連動レバー１０が図５において軸孔６を中心 にして時計回り方向に一体的に回転する。このとき、外側レバーハンドル８は止 め金板１８によって拘束されているが、外側レバーハンドル８は外側軸棒７の前 端丸軸部７ａに丸孔９にて嵌められているため、連動レバー１０の回転動作には 全く支障はなく、外側レバーハンドル８に対して外側軸棒７が空転することにな る。[0015] This rotation of the hook bolt 31 is performed via the inner shaft rod 28, the interlocking square rod 45, and the outer shaft rod 7. is transmitted to the hook bolt 31, and the interlocking lever 10 is centered on the shaft hole 6 in FIG. to rotate in a clockwise direction. At this time, the outer lever handle 8 is stopped. Although it is restrained by a metal plate 18, the outer lever handle 8 is located in front of the outer shaft rod 7. Since it is fitted into the end round shaft part 7a through the round hole 9, the rotational movement of the interlocking lever 10 is not possible. There was no problem at all, and the outer shaft rod 7 did not rotate idly relative to the outer lever handle 8. Ru.
【００１６】 このように内側レバーハンドル２９によって、フックボルト３１を解錠方向に 回転操作できるため、閉じ込められた作業員は即座に脱出することができ、凍死 や窒息死などの致命的事故に発展することがない。[0016] In this way, the inner lever handle 29 moves the hook bolt 31 in the unlocking direction. Since it can be rotated, trapped workers can quickly escape and avoid freezing to death. This will not lead to fatal accidents such as death from suffocation or suffocation.
