以下、添付図面中の参照符号を用いて説明すると、本考案の引き戸用ロック装 置では、引き戸４２の前面に突き当て固着されるフロントプレート１の下部に操 作用開口部２を設け、フロントプレート１の上部に錠前ユニット３を固着し、フ ロントプレート１の背面側の枠壁４に締付け固着され、引き戸４２の後面に突き 当て固着されるリアプレート５の中間部に軸孔６を設け、該軸孔６に軸棒７の後 端丸軸部７ｂを回転可能に嵌め込み、レバーハンドル８の基端部の丸孔９に軸棒 ７の前端丸軸部７ａを回転可能に嵌め込み、フックボルト１０の基端部の角孔１ １に軸棒７の中間軸部７ｃを回転不能に嵌め込んで、レバーハンドル８とフック ボルト１０を重ね合わせてフロントプレート１とリアプレート５の間に収容し、 レバーハンドル８の先端部を前記開口部２内に臨ませ、フックボルト１０の先端 部を枠壁４の側面開口１３から横向きに突出させる。 Hereinafter, using the reference numerals in the attached drawings, the lock device for sliding doors of the present invention will be explained. In the case of the A working opening 2 is provided, a lock unit 3 is fixed to the upper part of the front plate 1, and the lock unit 3 is fixed to the upper part of the front plate 1. It is tightened and fixed to the frame wall 4 on the rear side of the front plate 1, and abuts against the rear surface of the sliding door 42. A shaft hole 6 is provided in the middle part of the rear plate 5 to be fixed, and the rear plate 7 is inserted into the shaft hole 6. Rotatably fit the round end shaft portion 7b, and insert the shaft rod into the round hole 9 at the base end of the lever handle 8. Rotatably fit the front end round shaft portion 7a of 7 into the square hole 1 at the base end of the hook bolt 10. 1, the intermediate shaft portion 7c of the shaft rod 7 is fitted in a non-rotatable manner, and the lever handle 8 and the hook are attached. The bolts 10 are stacked and accommodated between the front plate 1 and the rear plate 5, With the tip of the lever handle 8 facing into the opening 2, insert the tip of the hook bolt 10. The part is made to project laterally from the side opening 13 of the frame wall 4.
【０００５】 レバーハンドル８の基端部の上面縁部に錠止突起１４と駆動突起１５を左右対 称に突設し、フックボルト１０の基端部の上面縁部に停止突起１６と受動突起１ ７を突設し、駆動突起１５と受動突起１７が当接した時、錠止突起１４と停止突 起１６の間に遊び間隔が残るように位置設定し、錠止突起１４に係合してレバー ハンドル８の回転を阻止する止め金板１８を錠前ユニット３のロータ１９に固着 し、フックボルト１０をバネ２１によって施錠方向に回転付勢し、レバーハンド ル８をバネ２５によって施錠位置へ復帰付勢し、フックボルト１０の中間部上面 を突き押すリリースロッド２８をリアプレート５側から操作可能に装備し、リリ ースロッド２８をバネ３１によって待機位置に復帰付勢する。[0005] A locking protrusion 14 and a driving protrusion 15 are arranged on the upper edge of the base end of the lever handle 8 in left and right pairs. A stop protrusion 16 and a passive protrusion 1 are provided on the upper edge of the proximal end of the hook bolt 10. 7 protrudes, and when the driving protrusion 15 and the passive protrusion 17 come into contact, the locking protrusion 14 and the stop protrusion Set the position so that there is a play gap between the levers 16 and engage the locking protrusions 14 to release the lever. A stop plate 18 that prevents rotation of the handle 8 is fixed to the rotor 19 of the lock unit 3. Then, the hook bolt 10 is biased to rotate in the locking direction by the spring 21, and the lever hand The hook bolt 8 is urged back to the locked position by the spring 25, and the middle upper surface of the hook bolt 10 is Equipped with a release rod 28 that can be operated from the rear plate 5 side to push the release The base rod 28 is urged back to the standby position by the spring 31.
【０００６】[0006]
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１０の先端部が 係合した施錠状態では、フックボルト１０の受動突起１７がレバーハンドル８の 駆動突起１５に当接している。また、錠前ユニット３の止め金板１８はレバーハ ンドル８の錠止突起１４に当接している。リリースロッド２８はフックボルト１ ０を押さない位置に保持されている。 The tip of the hook bolt 10 is attached to the receiver 22 on the side of a fixed frame such as a building or refrigerator body. In the engaged locked state, the passive protrusion 17 of the hook bolt 10 engages with the lever handle 8. It is in contact with the drive protrusion 15. Also, the stop plate 18 of the lock unit 3 is attached to the lever It is in contact with the locking protrusion 14 of the handle 8. Release rod 28 is hook bolt 1 It is held in a position where 0 is not pressed.
【０００７】 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によるレバーハンドル８の拘束が解除される。バネ２ ５の付勢に抗してレバーハンドル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、レバーハンドル８の駆動突起１５がフックボルト１０の受動突 起１７を押すため、フックボルト１０がバネ２１の付勢に抗して鎖線位置まで回 転し、先端部が受け金２２から離脱する。[0007] 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 lever handle 8 is released from being restrained by the stop plate 18. spring 2 5, move the lever handle 8 clockwise around the shaft hole 6 to the chain line position. When the lever handle 8 is rotated with In order to push the spring 17, the hook bolt 10 is rotated to the chain line position against the bias of the spring 21. Then, the tip portion is separated from the receiving metal 22.
【０００８】 このようにして解錠された引き戸４２は、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４２の開放後、レバーハンドル８ から手を離すと、レバーハンドル８とフックボルト１０はバネ２５、２１の付勢 によって元の位置に復帰する。引き戸４２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１０の先端部の円弧カム面４３に受け金２２が当接 する。そのため、フックボルト１０は軸孔６を中心に一旦退避回転する。[0008] When the sliding door 42 is unlocked in this way, the hand placed on the lever handle 8 It is opened by pulling it sideways. After opening the sliding door 42, the lever handle 8 When you release your hand, the lever handle 8 and the hook bolt 10 are biased by the springs 25 and 21. returns to its original position. When the sliding door 42 is moved linearly in the closing direction, it closes. The receiving metal 22 contacts the arcuate cam surface 43 at the tip of the hook bolt 10 at the terminal end of the hook bolt 10. do. Therefore, the hook bolt 10 is once retracted and rotated around the shaft hole 6.
【０００９】 引き戸４２が完全に閉鎖された時、フックボルト１０は若干角度逆回転し、フ ックボルト１０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をレバーハンドル８の錠止突 起１４に係合させる。[0009] When the sliding door 42 is completely closed, the hook bolt 10 rotates slightly in the opposite direction and the door is closed. The tip of the back bolt 10 and the receiver 22 automatically engage with each other. After closing, lock unit Rotate the rotor 19 of the lever handle 8 to the locking position, and move the stop plate 18 to the lock stop of the lever handle 8. 14.
【００１０】 冷蔵庫等の固定本体の内部に作業員が閉じ込められた時には、リリースロッド ２８を押し下げればよい。このリリースロッド２８の押し下げによってフックボ ルト１０は軸棒７と一体に軸孔６を中心に回転する。レバーハンドル８は軸棒７ の前端丸軸部７ａに丸孔９にて嵌められているため、レバーハンドル８が止め金 板１８によって回転を阻止されていても、フックボルト１０の回転動作には全く 支障はなく、レバーハンドル８に対して軸棒７が空転することになる。0010 If a worker is trapped inside a stationary body such as a refrigerator, use the release rod. All you have to do is press down on 28. By pushing down the release rod 28, the hook button is released. The bolt 10 rotates around the shaft hole 6 together with the shaft rod 7. The lever handle 8 is the shaft rod 7 Since the lever handle 8 is fitted into the front end round shaft part 7a through the round hole 9, the lever handle 8 is fitted with the stopper. Even if rotation is prevented by the plate 18, there is no rotational movement of the hook bolt 10. There is no problem and the shaft rod 7 will idle relative to the lever handle 8.
【００１１】 このようにリリースロッド２８によってフックボルト１０だけを選択的に回転 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。[0011] In this way, only the hook bolt 10 can be selectively rotated by the release rod 28. Because it can be operated, trapped workers can escape immediately and avoid freezing to death or suffocation. This will not lead to fatal accidents such as death from breathing.
