【課題を解決するための手段】 以下、添付図面中の参照符号を用いて説明 すると、本考案の閂式ラッチ装置では、扉1に固着されるケース2の貫通孔3に ラッチ棒4を摺動可能に挿通し、ラッチ棒4の先端部が係脱する受部7を固定枠 体6に設け、バネ8によってラッチ棒4を後退方向に摺動付勢する。Means for Solving the Problems Hereinafter, the description will be given with reference numerals in the accompanying drawings. In the bartack type latch device of the present invention, a latch bar 4 is slid into a through hole 3 of a case 2 fixed to a door 1. The fixing frame 6 is provided with a receiving portion 7 through which the latch rod 4 is movably inserted and whose tip portion is engaged and disengaged, and a spring 8 urges the latch rod 4 to slide backward.
【0007】 貫通孔3に交差したロック孔9をケース2に設け、ロック孔9に対面する受孔 10をラッチ棒4の周面に設け、先端部がロック孔9に係脱するロックピン11 を該受孔10に収容し、バネ12によって突出方向に摺動付勢し、ロックピン1 1の先端面13を突き押してロックピン11を受孔10に没入させる押しボタン 14をケース2に設け、押しボタン14をバネ15によって復帰付勢する。A lock hole 9 that intersects the through hole 3 is provided in the case 2, a receiving hole 10 that faces the lock hole 9 is provided on the peripheral surface of the latch rod 4, and a lock pin 11 whose tip is engaged with and disengaged from the lock hole 9 is provided. Is housed in the receiving hole 10 and is urged to slide in the protruding direction by a spring 12 to push the tip end surface 13 of the lock pin 11 to retract the lock pin 11 into the receiving hole 10. The spring 15 urges the push button 14 to return.
【0008】 扉1の閉鎖施錠状態では、ラッチ棒4の先端部が固定枠体6の受部7に係合し 、ラッチ棒4側のロックピン11がケース2側のロック孔9に係合し、該係合が バネ12によって保持されているため、ラッチ棒4はケース2に拘束されている 。ロックピン11の先端面13に押された押しボタン13はケース2の前面側に 最も突き出た待機位置にある。When the door 1 is closed and locked, the tip of the latch rod 4 engages with the receiving portion 7 of the fixed frame body 6, and the lock pin 11 on the latch rod 4 side engages with the lock hole 9 on the case 2 side. However, since the engagement is held by the spring 12, the latch bar 4 is restrained by the case 2. The push button 13 pushed by the tip end surface 13 of the lock pin 11 is at the standby position most protruding from the front side of the case 2.
【0009】 扉1の施錠を解除するには、押しボタン14をバネ15の付勢に抗して押し込 み、ロックピン11をバネ12に抗してケース2側のロック孔9から脱出させ、 全体をラッチ棒4側の受孔10内に押し戻す。ロックピン11の先端面13がラ ッチ棒4の周面と同じ面位置に来るまで押し戻された時、ケース2に対するラッ チ棒4の拘束が解除され、ラッチ棒4はバネ8の付勢によって直ちに後退摺動し 、ラッチ棒4の先端部が固定枠体6の受部7から脱出する。すなわち、押しボタ ン14を押し込むという単一操作によって、ラッチ棒4の拘束の解除と扉1の施 錠の解除が即座になされる。In order to unlock the door 1, the push button 14 is pushed against the bias of the spring 15, and the lock pin 11 is pushed against the spring 12 to be released from the lock hole 9 on the case 2 side. , Is pushed back into the receiving hole 10 on the latch rod 4 side. When the tip surface 13 of the lock pin 11 is pushed back to the same position as the peripheral surface of the latch bar 4, the latch bar 4 is released from the case 2 and the latch bar 4 is biased by the spring 8. Immediately afterward, the latch rod 4 slides backward, and the tip end portion of the latch bar 4 comes out of the receiving portion 7 of the fixed frame body 6. That is, by a single operation of pushing the push button 14, the restraint of the latch bar 4 and the lock of the door 1 are released immediately.
【0010】 押しボタン14から指を離すと、押しボタン14はバネ15の付勢によって前 記待機位置に復帰する。扉1はラッチ棒4を手前に引くこと等によって開放され る。扉1を閉鎖した後、バネ8に抗してラッチ棒4を前進摺動させると、ラッチ 棒4の先端部が固定枠体6の受部7に所定長さ係合した段階で、ラッチ棒4側の 受孔10がケース2側のロック孔9に対面する。そのため、ロックピン11はバ ネ12の付勢によってラッチ棒4側の受孔10から一部突出し、ケース2側のロ ック孔9に再度係合する。すなわち、ラッチ棒4を前進摺動させるという単一操 作によって、扉1の施錠の実行とラッチ棒4の拘束の実行が即座になされる。When the finger is released from the push button 14, the push button 14 is returned to the standby position by the bias of the spring 15. The door 1 is opened by pulling the latch bar 4 toward you. When the latch rod 4 is slid forward against the spring 8 after closing the door 1, the latch rod 4 is engaged with the receiving portion 7 of the fixed frame body 6 for a predetermined length when the latch rod 4 is slid forward. The receiving hole 10 on the 4 side faces the lock hole 9 on the case 2 side. Therefore, the lock pin 11 partially projects from the receiving hole 10 on the latch rod 4 side by the biasing force of the vane 12 and re-engages with the locking hole 9 on the case 2 side. That is, the door 1 is locked and the latch bar 4 is restrained immediately by a single operation of sliding the latch bar 4 forward.
