[Action]

 In the accordion door one-touch lock device for a box-type truck with the above configuration, when the door is open, the operating part of the operating lever of the moving pillar is pulled in the direction opposite to the direction in which the door is closed, and the operating lever is pulled. The engaging pin is held in the second recess of the engaging piece of the engaging member. At that time, the hooks near the upper and lower ends of the movable column project from the movable column toward the fixed column, and are rotatably held with the tip slightly upward.

Next, when the door is closed, the door is closed with the operation part of the operation lever being in a state where the door is opened, and when the moving pillar comes into contact with the fixed pillar, the hook portion at the tip of the hook is closed. Get over the fixed pin of the fixed column. At the same time, one end of the lock member projecting from the side end surface of the moving column is pushed into the moving column, and the upward protrusion of the locking member lifts the stopper pin at the tip of the engaging piece of the engaging member, By the action of the spring, the operating lever moves toward the fixed column, the stopper pin gets over the upward projection, and the action of the second spring causes the engaging piece to fall downward, causing the engaging pin to move to the first side of the engaging piece. As the hook fits in the recess and moves so as to be pulled into the moving column, the hook is fixed by pulling it horizontally by hooking the fixing pin of the fixing column. This state is the locked state.

When the lock is released, the disengagement piece of the engagement member is moved in the direction in which the engagement piece is disengaged from the engagement pin in the concave portion of the moving column, and the stopper pin is caused to project upward from the engagement member. By overcoming the start and returning it to its original position, and returning the lock member to its original position by the third spring, the operating lever is released and the operating portion of the operating lever is fully filled in the direction opposite to the fixed column. When pulled, the hook protrudes toward the fixed column, the tip of the hook greatly points up, and the fixing pin comes off. When the door is opened in this state, the hook separates from the fixed column. At this time, when the operating portion of the operating lever is released from the hand, the engaging pin of the operating lever fits into the second concave portion of the engaging piece of the engaging member and is held in the open state.
