The panel 11 closest to the storage platform 18 in the closed state of FIG. 1 (hereinafter referred to as the first panel) has an arm member 21 attached to its left end.
is rotatably attached to the storage base 18 by a rotation pin 22. Accordingly, the first panel 11 can be rotated counterclockwise about the pivot pin 22 from the horizontal position shown and placed in an upright position. When numbering in order from the first panel 11 to the right, all odd-numbered panels 11, 13, and 15 have horizontal protrusions 4A, 4B, and 4C on their side edges, respectively, and the final corner numbered panel, that is, the sixth panel. 16 is provided with a connecting fitting 5 hanging down from its side edge portion.
If necessary, coaxial rollers may be attached to the horizontal projections 4A, 4B, and 4C. Also, the second and fourth
The sixth panels 12, 14, and 16 are each provided with wheels 24A, 24B, and 24C that roll along tracks (not shown) on the hatch edge member 17.

The opening/closing device 10 of the present invention includes a rotary arm 1 whose one end is rotatably attached to a support base 9 provided on a deck 19 adjacent to a storage base 18 with a horizontal pin 6, A hydraulic jack 2 is rotatably mounted on the deck 19 and has a movable end (upper end) connected to the rotating arm 1, and a pair of sprockets 7 and 8 are mounted on both ends of the hatch edge material 17. It is composed of an endless chain 3.

The rotating arm 1 has a standby position (the position shown in FIG. 1) in which it extends horizontally from the horizontal pin 6 toward the port edge member 17 at the lower level of the horizontal projections 4A, 4B, and 4C by the operation of the hydraulic jack 2; It rotates back and forth between the horizontal pin 6 and the raised position (position shown in Figure 2) extending vertically upward, and has a length sufficient to extend beyond the horizontal protrusion 4A of the first panel 11 to the right. shall have.

One of the pair of sprockets 7 and 8 to which the endless chain 3 is hung is connected to an appropriate drive source (not shown). The endless chain 3 is placed at a position where its upper running portion 3U faces the lower surface of each of the corner panel 11-16, and the last corner panel 16
A connecting fitting S hanging from the side edge of the endless chain 3 is connected to the upper run 3U. Although not shown, the endless chain 3 is assumed to be equipped with a required guide sprocket and slack absorption mechanism. The drive source connected to the sprocket 7 or 8 is of a reversible type, and if necessary, a suitable ratchet mechanism and locking mechanism are installed between the drive shaft and the sprocket 7 or 8 attached thereto.

During operation, when opening the cargo area from the closed state shown in FIG.
To rotate the first panel 11 counterclockwise around the rotation pin 22 in the counterclockwise direction in FIG.
2 approaches the first panel 11 in an A-shape, and the subsequent panels 13, 14, 15, 16 approach the storage platform 18 along the track.
It is dragged in the direction of and reaches the position shown in Figure 2. At this time, the connecting fitting 5 hanging down from the last corner number panel 16 pulls the upper running part 3U of the endless chain 3 to the left end, but since the drive sprocket 8 is equipped with a ratchet mechanism, the endless chain 3 The movement of the corner number panel 16 is followed. In the position shown in FIG. 2, the horizontal protrusion 4B of the third panel 13
be placed at a position that does not prevent it from returning to its horizontal position.

That is, the second panel 12 is not brought into close contact with the first panel 11, leaving some room for the subsequent panels 13, 14, 15, and 16 to move further toward the storage stand 18. Then, the rotating arm 1 is returned to the horizontal standby position, but
The endless chain 3 keeps the first and second panels 11 and 12 upright and does not return all the panels to the closed position. Next, by operating the endless chain 3 and pressing the final corner numbered panel 16 toward the storage stand 18 via the connecting fitting 5, the first and second panels 11 and 12 are brought into close contact and are completely placed in the storage position. The horizontal protrusion 4B of the third panel 13 is placed on top of the rotating arm 1 to reach the state shown in FIG. Therefore, when the rotating arm 1 is rotated in the counterclockwise direction A around the horizontal pin 6 by the driving source 2, the state shown in FIG. 4 is obtained. At this time, as in the case of FIG. 2, the horizontal protrusion 4C of the fifth panel 15 remains in a position that does not prevent the rotating arm 1 from returning to the horizontal standby position. Then, the rotating arm 1 is returned to the horizontal standby position and the endless chain 3 is operated to move the final corner number panel 16.
When pressing toward the storage platform 18, the third and fourth
The panels 13 and 14 are brought into close contact with each other and accurately placed in the retracted position, resulting in the state shown in FIG. When the rotating arm 1 is subsequently rotated counterclockwise around the horizontal pin 6 by the drive source 2, the fifth panel 15 is pulled up and the state shown in FIG. 6 is achieved. Then, return the rotating arm 1 to the horizontal standby position, press the last corner numbered panel 16 toward the storage stand 18 using the endless chain 3, and all the panels 11-16
are placed in a close storage position. As explained above, by repeating the lifting operation shown in FIG. 2 three times, the opening operation for six panels is completed. The present invention can also be applied to the case of a panel with a diagonal number of sheets.

When closing from the stowed position, all the panels 11-16 are pulled out onto the hatch rim 17 by means of an endless chain in the reverse order of the above process. That is, from the storage position shown in FIG.
is pulled onto the berth edge material 17 by the endless chain 3. During this movement, the rotating arm 1 gradually rotates clockwise while engaging with the horizontal protrusion 4C of the fifth panel 15, and both panels 15, 16 to prevent sudden falls or falls. Similarly, the fourth and third panels 14 and 1
When drawing out panel 3, the rotating arm 1 engages with the horizontal protrusion 4B, and when drawing out the second and first panels 12 and 11, the rotating arm 1 engages with the horizontal protrusion 4A, supporting the weight of the panel while rotating and falling. Pull out panels one after another while controlling the speed.

As shown above, according to the present invention, the entire opening/closing device is extremely simplified, and only the rotating arm 1 and the endless chain 3, one for each side, are provided as constituent parts, and no other parts are required. be. Therefore, not only the type and number of component parts are greatly reduced, resulting in cost savings, but also the operation and maintenance are simple and easy, resulting in a great saving in labor during use.
