構が使用されている。As a door opening and closing mechanism, one that slides the door laterally to open and close the front is widely used.
Since this kind of door cannot open the part corresponding to the door pocket,
The frontage may not be wide open. However, it is necessary to open the frontage widely when large luggage is taken in and out, or when evacuating due to a fire or the like. For this reason, conventionally, the door is usually opened by sliding it first to open the frontage as much as necessary, and in an emergency, the door is opened and closed by swinging to open the front door more widely. The mechanism is being used.

When the lock is released, the operation member 62, the sliding member 56, and the like are pulled by the elastic force of the equal tension spring 53 along the guide member 55 toward the winding portion 54 side of the spring 53, and at the same time, the operation member is moved. Since 62 presses the pressing plate 52, the pressing plate 52, the traveling body 8, the movable door 1 and the like are moved to the winding portion 54 side of the spring 53, and the movable door 1 is opened at a normal opening or more (FIG. 2). Slide it to the position of Y) and move it. When the operating member 62 is pulled by the elastic force of the equal tension spring 53, the operating member 62 swings around the pin 63 as a fulcrum, and the lower end portion 62a of the operating member 62 opens at the open end of the swinging member 60. Since the side upper surface 60c is pressed, the open end side of the swinging member 60 is pressed via the compression spring 60a and moves downward. Then, the swing member 60 presses the upper surface of the pressing member 61, and the lower surface of the pressing member 61 is pressed against the upper surface of the guide member 55, so that a braking action is performed. In this way, the pressing member 61
Is pressed against the guide member 55 by the elastic force of the equal tension spring 53, and some braking action is performed, so that the braking is performed.
The sliding member 56, the traveling body 8, the moving door 1 and the like do not move suddenly, and therefore the moving door 1 and the like are not damaged due to impact and can be reliably used for a long period of time. . When the moving door 1 is fully closed, it moves from O to Y in FIG. 2 at a time, and the normal opening (X in FIG. 2).
When it is located at, move from X to Y, that is, the moving door 1
Is automatically moved by sliding to a position where the opening is larger than the normal opening (Y in FIG. 2). Then, the inclined surface 24 of the pressing member 23 fixed to the traveling body 8 presses the inclined surface 18 of the swinging member 15 while sliding, so that the swinging member 15 moves.
6 as a fulcrum, and the locking body 1 at the tip of the rocking member 15
7 is lifted up and comes out of the locking hole 22 on the fixed door 2 side, so that the fixed door 2 is unlocked. At the same time, moving door 1
Is moved over the normal opening degree, the inclined surface 34 of the pressing member 33 fixed to the frame body 5 pushes up the rotating body 32a of the locking plate 27, so that the locking plate 27 attached to the traveling body 8 moves upward. By moving, the locking portion 30 formed on the lower portion of the locking plate 27 is lifted up above the locking member 31 to unlock the moving door 1. Then, when both doors 1 and 2 are stacked in the width direction and the inside is pressed, the fixed door 2 is fixed to the pins 3 and 4.
With the fulcrum as the fulcrum, and the movable door 1 swings and opens in the direction of the arrow B with the support shaft 10 and the pin 11 as the fulcrum, respectively.
The frontage can be widely opened.
