In FIG. 1, the storage of the refrigerator 1 is opened and closed by a pair of double-opening doors. The first and second doors forming the pair of doors are hinged on the outside of the refrigerator 1 to each other. Supported.

At the open end of the first door 2, a second door 3
A sealing column 4 that rotates so as to advance and retreat to the side is attached. The operation of the seal pillar 4 is such that the seal pillar 4 is in the inner turning position, that is, in the retracted position where it does not protrude from the open end of the first door 2 in the state shown in FIG. The retracted position is held until the first door 2 is closed and the second door 3 is opened, as shown in FIG. This is because the sealing column 4 is urged by the urging means (not shown) toward the retracted position.

Next, when the second door 3 is closed, a sealing column driving device (described in detail later) disposed on the upper inner surface of the storage in cooperation with the closing operation urges the sealing column 4 to the retracted position. As shown in FIG. 1C, the sealing column 4 is
The first door 2 and the second door 2 are rotated to the forward position protruding toward the door 3 side.

Both the doors 3 are closed and the guide body 18 and thus the guide body 1
The seal column with the upper end 8 is parallel to the opening surface of the refrigerator and can be sealed. FIG. 5B shows a state in which the second door 3 is slightly opened, and FIG.
This is a case where the door 3 is further opened. At this time, it can be seen that the guide body 18 and thus the seal pillar rotate along the door back body, that is, to the retracted position of the first door 2. Further, when the second door 3 is closed as shown by the arrow in FIG. 5D, the guide body 18 and thus the sealing column rotate clockwise and move in the direction shown in FIG. 5A. You can see that.

As described above, the interlocking lever 6 is rotated by the projection 16 of the second door 3, and the driving pin 13 moves in the pin sliding slot 12 and the pin guide groove 9 in response to the rotation of the interlocking lever 6. As a result, the guide body 18 attached to the upper end of the sealing column is rotated clockwise or counterclockwise, so that the rotation of the sealing column 4 can be performed smoothly.

Next, the state shown in FIGS. 6A, 6B, and 6C is such that when the first door 2 is closed and the second door 3 is opened, the guide body 18 and the sealing column 4 are moved. As shown in (b), when the robot is erroneously rotated with an article or a finger so as to advance in the direction of the second door 3, the projection 16 of the second door 3 is indicated by a diagonal line outside the action section 11. The abutment of the illustrated first abutment portion 11a makes it impossible to sufficiently rotate the interlocking lever 6 in the counterclockwise direction, so that the second door 3 cannot be closed, and the first and second doors 2 and 2 in the closed state. 3, a gap G is formed, and a step occurs. In this case, once again, the first door 2 and the second door 3
Need to be opened and closed again.

7 (a), 7 (b) and 7 (c) show the state when the first door 2 is opened and the guide column 18 is moved to the forward position as shown in FIG. 7 (a). It is assumed that the door is closed as shown in FIG. In this case, when the second door 3 is closed as shown in FIGS. 7B and 7C, the projections 16 of the second door 3 become the second contact portions, which are the walls of the action portion 11 and are hatched. In contact with the portion 11b, the interlocking lever 6 cannot be sufficiently rotated in the counterclockwise direction, so that the second door 3 cannot be closed, and between the first door 2 and the second door 3, There is a gap called G and a step occurs. In this case, it is necessary to open the first door 2 and the second door 3 again and then close them.

As described above, in the present invention, the user can be alerted by forcibly providing the action portion 11 as the hatched portions 11a and 11b in the half open state of the door.
