Generally, hatches are collectively referred to as the hatches and hatches of ships, and in particular, the through-hatches which are opened on the deck for loading or unloading cargo or for entering and exiting people. These hatches are manufactured to the minimum size necessary for the strength and safety of the hull. However, in view of the characteristics of the large hull, it is generally preferable to increase the efficiency of the unloading.

The hatch cover is called a cargo hatch to load and lower the cargo into the dock. A hatch coam of sufficient height is installed around the hatch to prevent seawater from flowing into the ship, and covering the upper part is called a hatch cover.

On the other hand, among conventional hatch covers, a hatch cover used for an exhaust pipe or the like for ventilation inside a ship is attached to the hull wall in a vertical direction. For ventilation, the hatch cover rotates forward and opens and is turned downward to be shielded. In this case, the operator opens or closes the hatch cover. When the hatch cover is opened, a large amount of force is required to lift the hatch cover up, and when the wind is blowing, there is a risk of accident. Further, in the case of a heavy-weight hatch cover, when the hatch cover is moved downward, acceleration is applied to the hatch cover to break the hatch cover, or the hatch cover is detached due to breakage of the hinge portion.

In this regard, Japanese Patent Application Publication No. 10-1345195 (Dec. 31, 2013) discloses a hatch cover device for ships, which is an invention of the applicant of the present invention, and it is necessary to move the hatch cover upward in opening the hatch cover In the narrow space due to the configuration, difficulties were encountered in opening the hatch cover.

On the other hand, the hatch cover is provided with a louver in a frame formed with a rectangular hollow for ventilation and ventilation, in a state of being opened in a closed state, in direct sunlight or rain.

However, a conventional louver installed on a hatch cover has a problem in that it is difficult and complicated to process because a worker has to attach (attach) each of the long and thin barbs to each other at a predetermined interval, There is a problem that productivity is poor due to poor working efficiency.

In addition, there is a problem in that manufacturing costs due to high wage payment are greatly increased because skilled attaching experts are required for welding, welding and grinding operations.

In addition, if an erroneous operation occurs, a complicated and complicated process must be performed again after the barbed plate is cut again, which can cause a serious problem in production.
