Claims

[Scope of Claim for Utility Model Registration] 1. Consisting of three panels 2, 3, and 4 for releasably closing the opening of hatch 1 opening in the inner deck of a ship, etc. The first panel 2 near one end of the section is pivoted at its adjacent side to the hull 10 via a hinge ₂₁ ,
An adjacent side of the second panel 3 is pivotally connected to the other side via a hinge ₃₁ , and the other side of the second panel 3 opposite to this side and the side of the third panel 4 opposite to this other side. is pivotally connected via hinges 3 ₂ , 4 ₁ to a bogie bogie 5 running on a rail ₆ installed in parallel on opposing hatch coamings 1 1 that bound the opening of the hatch 1 , A hatch of the type in which a hydraulic cylinder is arranged between the third panel 4 and the bogie truck 5 in order to allow the third panel 4 to rotate freely around the hinge ₄₁ perpendicularly to the bogie truck 5. In the cover, a hydraulic cylinder 10 is arranged inside the third panel 4 in a direction parallel to the rail 6, and one end thereof is rotatably connected to the third panel 4 via a pin 13, and the other end is connected to the second panel 4. A pin is attached to the other end of the plate member 15, which is arranged parallel to the direction of the rail 6 inside the third panel 3 and the third panel 4, and whose one end is pivotally connected to the second panel 3 via the pin 19. 16, and this plate member 15 is pivotally connected to a support member 17 fixed to the third panel 4, which in this case is a pivotally connected portion with the second and third panels 3, 4 of the bogie 5. Hinge 3 ₂ ,
4. The support member ₁ is a pivot point between each axis of the pin 19 and the third panel 4 and the axis of the pin 19 is a pivot point between each axis of the plate member 15 and the second panel 3 of the plate member 15.
A hatch cover opening/closing device in which the axes of No. 7 and No. 7 are on the same line. 2 Pin 1 to third panel 4 of hydraulic cylinder 10
3 is the cylinder end ₁₀₁ of the hydraulic cylinder 10, and the pivot point 16 to the plate member 15 is the piston rod end _141. A hatch cover opening/closing device according to claim 1 of the utility model registration claim. 3.
