You can switch with.

The first-axis lock mechanism 35 and the second-axis lock mechanism 45 are configured to have play in the locked state, and the first rotation angle and the second rotation angle are minute angles even in the locked state. It can be changed.

As a result, as will be described later, when the sealing lever 50 is closed, the first rotating mechanism 30 and the second rotating mechanism 40 rotate at a slight angle, so that the sealability of the hold door 10 can be improved. .. In order to realize high sealing performance, it is desirable that the play of the second shaft lock mechanism 45 is about 10 °.

Specifically, in the second rotation mechanism 40, the inner diameters of the second lock holes 47a and 48a are slightly larger than the outer diameter of the second lock bolt 46.

Three sealing levers 50 are installed on each side of the peripheral edge of the surface (second surface) of the door plate 11 on the warehouse 4 side, and are rotatable around a horizontal axis perpendicular to the surface of the door plate 11. It is installed in. With the hold door 10 closed, the sealing lever 50 is rotated in the closing direction to project the tip locking portion toward the luggage compartment wall 6, so that the tip locking portion engages with the luggage compartment wall 6. , The door plate 11 is configured to be crimped to the luggage compartment wall 6.

A packing 12 for sealing is installed on the peripheral edge of the surface of the door plate 11 on the warehouse side, and by closing the hold lever 50 after closing the hold door 10, the door plate 11 is brought into close contact with the luggage compartment wall 6. It can be sealed.

The configuration of the hold door 10 has been described above, but subsequently, the opening / closing work of the hold door 10 will be described. First, a procedure for opening the hold door 10 from a closed state of 0 ° to an intermediate opening state of 90 ° or a maximum opening of 180 ° will be described.

When the hold door 10 is closed, the rotation angle of the first rotation mechanism 30 and the second rotation mechanism 40 is 0 °, and all the sealing levers 50 are closed. At this time, the first rotation mechanism 30 is in a rotatable free state, and the second rotation mechanism 40 is fixedly locked at a second rotation angle of 0 ° by the second shaft lock mechanism 45.

When opening the hold door 10, first, all the sealing levers 50 are opened to release the crimping state of the door plate 11 to the luggage compartment wall 6. Then, only the first rotation mechanism 30 in the free state is rotatable, and the door plate 11 can rotate only around the first rotation shaft 31. In this state, the first rotation mechanism 30 is opened so that the first rotation angle is from 0 ° to 90 °.

Specifically, when the operator moves the door plate 11 in the opening direction, the relative position between the intermediate body 20 locked by the second axis lock mechanism 45 and the door plate 11 remains the same, and the door plate 11 is in a free state. Only one rotation mechanism 30 rotates, and the door plate 11 integrated with the intermediate 20 opens 90 ° with respect to the luggage compartment wall 6 around the first rotation shaft 31. Even if the first rotation mechanism 30 is opened more than 90 °, the inner side wall of the intermediate body 20 cannot be opened wide because it interferes with the opening edge of the luggage compartment wall 6.

When the first shaft lock mechanism 35 is locked while the first rotation mechanism 30 is opened by 90 ° in this way, the hold door 10 is in an intermediate opening state where it is opened by 90 °. In this intermediate opening state, the first shaft lock mechanism 35 and the second shaft lock mechanism 45 are in the locked state, and the door plate 11 is fixed in a state of being opened by 90 °. If the work in the luggage compartment 3 can be sufficiently performed even in the intermediate opening state and there is no problem, the opening work of the hold door 10 is completed.

Further, when the hold door 10 is to be opened up to 180 ° (for example, when the forklift placed in the warehouse 4 is to be wrapped around the back side of the door plate 11 in the intermediate opening state), the intermediate opening state is started. The second shaft lock mechanism 45 is set to the free state. Then, the intermediate body 20 remains relatively fixed to the luggage compartment wall 6 by the first shaft lock mechanism 35, and the door plate 11 can rotate around the second rotation shaft 41 with respect to the intermediate body 20. Become.

In this state, the second rotation angle of the second rotation mechanism 40 in the free state is opened from 0 ° to 90 °. Specifically, when the operator moves the door plate 11 in the opening direction, the relative positions of the luggage compartment wall 6 and the intermediate body 20 locked by the first shaft lock mechanism 35 remain the same and are in a free state. Only the second rotation mechanism 40 rotates, and the door plate 11 opens 90 ° with respect to the intermediate 20 around the second rotation shaft 41. Even if the second rotation mechanism 40 is opened more than 90 °, the side edge portion of the door plate 11 may interfere with the inner side wall of the intermediate body 20, the luggage compartment wall 6, etc., and the door plate 11 may be opened wide. Can not.

In this way, when both the first rotation mechanism 30 and the second rotation mechanism 40 are opened by 90 °, the hold door 10 is in the maximum opening state of 180 °. When the door plate 11 is fixed in this maximum opening state, it may be fixed to the wall or floor of the ship by using a D ring or the like.

Subsequently, a procedure for closing the hold door 10 in the maximum opening state to the closed state will be described. First, the member that fixes the door plate 11 such as the D ring to the wall or floor of the ship is released, and the second rotation mechanism 40 having the second rotation angle of 90 ° is closed to 0 °.

As described above, in the maximum opening state where the hold door 10 is opened 180 °, the first rotation mechanism 30 having a first rotation angle of 90 ° is locked by the first axis lock mechanism 35, and the second rotation angle is Since the second rotation mechanism 40 at 90 ° is in a free state, when the D ring or the like is removed and the door plate 11 is moved in the closing direction, the second rotation mechanism 40 is operated until the second rotation angle becomes 0 °. Only rotates.

When the second shaft lock mechanism 45 is locked when the second rotation angle is 0 °, the hold door 10 is in an intermediate opening state opened by 90 °. When closing from the intermediate opening state to the closed state, first, the first shaft lock mechanism 35 is set to the free state. Then, the door plate 11 remains relatively fixed to the intermediate body 20 by the second shaft lock mechanism 45, and the intermediate body 20 can rotate around the first rotation shaft 31 with respect to the luggage compartment wall 6. Become.

In this state, the first rotation angle of the first rotation mechanism 30 in the free state is closed from 90 ° to 0 °. Specifically, when the operator moves the door plate 11 in the closing direction, the relative position between the door plate 11 locked by the second axis lock mechanism 45 and the intermediate 20 remains the same, and the second is in a free state. Only one rotation mechanism 30 rotates, and the door plate 11 integrated with the intermediate 20 rotates around the first rotation shaft 31 with respect to the luggage compartment wall 6 and closes to 0 °.

When the first rotation mechanism 30 is closed to 0 °, the rotation angles of both the first rotation mechanism 30 and the second rotation mechanism 40 become 0 °, and further, by closing all the sealing levers 50, The hold door 10 is closed. In the closed state, the first shaft lock mechanism 35 is in the free state, and the second shaft lock mechanism 45 is in the locked state.

By closing the sealing lever 50, the packing 12 at the peripheral edge of the door plate 11 is pressed against the opening edge of the luggage compartment wall 6. At this time, since the first rotation mechanism 30 is in the free state and the second shaft lock mechanism 45 that locks the second rotation mechanism 40 has play, the door is pressed against the luggage compartment wall 6 by the sealing lever 50. The plate 11 rotates around the first rotation shaft 31 and the second rotation shaft 41 for fine adjustment so that the entire plate 11 is uniformly pressed against the luggage compartment wall 6, and the hold door 10 is sealed. Can be improved.

If the door opening / closing member 15 has only one rotation axis, only the rotation angle of the door plate 11 with respect to the luggage compartment wall 6 can be adjusted. However, in the present embodiment, the door opening / closing member 15 has the first rotation shaft 31 and By providing the second rotating shaft 41, it is possible to adjust the parallelism of the door plate 11 with respect to the luggage compartment wall 6 as described above.

Although the present embodiment has been described above, according to the present embodiment, in the door structure that rotatably supports the door plate 11 with respect to the luggage compartment wall 6, the first rotating mechanism 30 that sandwiches the intermediate body 20 is used. A predetermined place on the second surface side of the luggage compartment wall 6 and a predetermined place on the second surface side of the door plate 11 are connected via the second rotation mechanism 40, and the door plate 11 is connected. It is possible to realize a door structure in which it is not necessary to provide a protrusion on the luggage compartment 3 side (first surface side) in the opening direction.

Therefore, according to the present embodiment, even if the load in the luggage compartment 3 is a hard heavy object, it is possible to prevent an accident in which the load collides with a projecting object on the luggage compartment 3 side of the door and is damaged. can.

Further, in the present embodiment, the first axis lock mechanism 35 of the first rotation mechanism 30 and the second axis lock mechanism 45 of the second rotation mechanism 40 are configured to have play in the locked state and are closed. By finely adjusting the posture of the door plate 11 with respect to the luggage compartment wall 6 in the state, the door plate 11 can be evenly brought into close contact with the luggage compartment wall 6, and high watertightness of the hold door 10 is realized. be able to.

Although the embodiments of the present invention have been described above, the embodiments of the present invention are not limited to the above embodiments, and various modifications can be made without departing from the gist of the present invention. For example, the shape, size, material, etc. of each member constituting the hold door can be changed as appropriate.

Further, in the above embodiment, the hold door installed in the luggage compartment of the ship has been described as an example, but the present invention has a door other than the luggage compartment of the ship, a door of a warehouse on land, and the like. It can be applied to hinged door type doors for other purposes as appropriate, such as truck bed doors. Further, in the above embodiment, the double door type door has been described, but of course, the present invention can also be applied to the single door type door.

Further, in the above embodiment, the lock angle by the first axis lock mechanism of the first rotation mechanism is 90 °, and the lock angle by the second axis lock mechanism of the second rotation mechanism is 0 °. The lock angle can be changed as appropriate. For example, the lock angle of the first-axis lock mechanism may be 60 °, and the lock angle of the second-axis lock mechanism may be 30 °. Further, instead of setting the lock angle of the lock mechanism as a fixed value, it may be possible to fix the lock mechanism in multiple stages.
