The restraint position as shown in FIG. 8 that restrains and prevents movement in the release position and the restraints of both latches (15) and (15) are released, and both latches (15) and (15) move to the release position. It is possible to move to a non-restraining position as shown in FIG. 10, and in conjunction with the movement of one of the latches (15) (15) from the locking position to the releasing position, A restraining means (29) adapted to be moved to the restraining position is provided.

この例では、拘束手段(29)は、ケース(25)内に、前方の拘束位置と後方の非拘束位置とに前後方向に摺動可能として装着され、かつ後端中央とケース(25)の後片(25c)との間に縮設された圧縮コイルばね(30)等の付勢手段により前方に向かって付勢された平面視ほぼ門型の拘束部材(31)と、この拘束部材(31)の内側において、ケース(25)の底片(25a)に上下方向を向く左右1対の軸(32)(32)をもってそれぞれ枢着された左右1対の中間部材(33)(33)とからなっている。   In this example, the restraining means (29) is mounted in the case (25) so as to be slidable in the front-rear direction between the front restraint position and the rear non-restraint position, and the rear end center and the case (25). A substantially gate-shaped restraining member (31) in plan view biased toward the front by a biasing means such as a compression coil spring (30) that is compressed between the rear piece (25c), and this restraining member ( 31) a pair of left and right intermediate members (33) (33) pivotally attached to the bottom piece (25a) of the case (25) with a pair of left and right shafts (32) and (32), respectively. It is made up of.

左右の中間部材(33)(33)は、左右方向を向く横向き腕部(33a)の中間部より、前向き腕部(33b)が前方に向けて延出する平面視ほぼT字状をなしている。前向き腕部(33b)の先端には、後方に向かって拡開するように傾斜する傾斜縁(33c)が設けられている。   The left and right intermediate members (33) and (33) are substantially T-shaped in a plan view in which the forward arm portion (33b) extends forward from the intermediate portion of the lateral arm portion (33a) facing left and right. Yes. An inclined edge (33c) that inclines so as to expand rearward is provided at the tip of the forward arm (33b).

各中間部材(33)は、係止位置から解除位置へ移動する各ラッチ(15)の先端により、前向き腕部(33b)の外側縁が内向きに押動されて、図8に示す不作動位置から図10の左方に示す作動位置へ回動させられ、横向き腕部(33a)の先端で、拘束部材(31)のほぼ中央を、圧縮コイルばね(30)の付勢力に抗して、拘束位置から非拘束位置に向かって後方に押動する。   Each intermediate member (33) is inoperative as shown in FIG. 8 because the outer edge of the forward arm (33b) is pushed inward by the tip of each latch (15) moving from the locking position to the release position. 10 to the operating position shown on the left side of FIG. 10, and at the tip of the lateral arm (33a), substantially the center of the restraining member (31) is resisted against the biasing force of the compression coil spring (30). Then, it is pushed backward from the restraint position toward the non-restraint position.

また、後述する施錠機構(35)により、拘束部材(31)が拘束位置に係止された施錠時には、両中間部材(33)(33)は、拘束部材(31)により不作動位置に拘束され、前向き腕部(33b)の外側縁で各ラッチ(15)の係止位置から解除位置への移動を阻止する。   When the locking member (31) is locked in the locked position by the locking mechanism (35) described later, the intermediate members (33) and (33) are locked in the inoperative position by the locking member (31). The movement of each latch (15) from the locking position to the releasing position is prevented at the outer edge of the forward arm (33b).

図11に示すように、ラッチ(15)が係止位置に位置している状態で、扉(6)を閉じた際は、まずラッチ(15)の傾斜縁(15d)が係合ブロック(26)に当接して、ラッチ(15)は解除位置側に押動されつつ、係合孔(27)内に進入し、ついで、ラッチ(15)の先端で、中間部材(33)の前向き腕部(33b)の先端に設けられた傾斜縁(33c)がが押動されて、中間部材(33)は不作動位置から作動位置へ回動させられ、それによって、上記と同様に横向き腕部(33a)の先端で、拘束部材(31)のほぼ中央を、圧縮コイルばね(30)の付勢力に抗して、非拘束位置に向かって後方に押動する。
したがって、閉扉操作時に、ラッチ(15)の先端が中間部材(33)に当接して破損するおそれはない。
As shown in FIG. 11, when the door (6) is closed in a state where the latch (15) is located at the locking position, the inclined edge (15d) of the latch (15) is first moved to the engagement block (26). ), The latch (15) enters the engagement hole (27) while being pushed toward the release position, and then at the tip of the latch (15), the forward arm portion of the intermediate member (33) The inclined edge (33c) provided at the tip of (33b) is pushed, and the intermediate member (33) is rotated from the non-operating position to the operating position. At the tip of 33a), the substantial center of the restraining member (31) is pushed backward toward the non-restraining position against the urging force of the compression coil spring (30).
Therefore, there is no possibility that the tip of the latch (15) contacts the intermediate member (33) and is damaged during the closing operation.
