The present invention relates to an opening leaf for closing an opening of a boat cabin, consisting of at least two translatably movable wings: a slave wing (12) which has locking means capable of immobilizing it in its closed position, these locking means being controlled by a control element which is movable between a locking position and an unlocking position, and a master wing (11) which has an actuating part (116) able to come into contact with the control element, when the master wing (11) moves towards its open position in front of the slave wing (12) with the latter immobilized in its closed position, in order to place the control element in its unlocking position, and to secure the slave wing (12) to the master wing (11).

Opening for closing an opening in a boat cabin, consisting of at least two movable leaves in translation between a closed position and an open position, a first of said leaves, called the master leaf, having means for locking its position relative to the frame of the opening, in its closed position, these locking means being actuable by a user, the second of said leaves, called the slave leaf, having means for locking its position relative to the frame of said opening, these locking means not being actuable by a user, the master leaf having actuating means allowing the sliding movement of the master leaf in front of the slave leaf, from its open position to its closed position, to simultaneously cause: the unlocking of the locking means of the position of the slave leaf relative to the frame of said opening,and the joining of the slave leaf and the master leaf.

TITLE: Locking device for a boat door, and door equipped with such a locking device. The present invention relates to a door for closing an opening in a boat cabin, consisting of at least two sliding leaves: a slave leaf (12) which has locking means capable of blocking it in its closed position, these locking means being controlled by a control element movable between a locking position and an unlocking position, and a master leaf (11) which has an actuating part (116) capable of coming into contact with the control element, when the master leaf (11) moves towards its open position in front of the slave leaf (12) blocked in its closed position, in order to place the control element in its unlocking position, and to secure the slave leaf (12) to the master leaf (11).

We provide a hydrostatic testing device for aluminum portholes. [Solution] Specifically, the present invention relates to a hydrostatic testing apparatus for checking the leakage phenomenon in aluminum portholes, comprising a jig for fixing the aluminum porthole, and a water tank containing water, configured so that the aluminum porthole fixed by the jig and lowered is immersed in the water. In other words, the apparatus tests for defects in the aluminum porthole by checking the phenomenon of water leaking (leakage) from the aluminum porthole immersed in the water tank, and for more accurate testing, the present invention relates to a hydrostatic testing apparatus for aluminum portholes configured so that the fixed aluminum porthole can move in a total of four directions: forward, backward, left, and right.

The invention relates to the technical field of ship defense devices, in particular to a ship cab anti-piracy device which comprises a cabin plate piece, the cabin plate piece comprises a first cabin plate and a second cabin plate, windows are arranged on the side wall of the first cabin plate and the side wall of the second cabin plate, the first cabin plate and the second cabin plate are different in size, and the first cabin plate and the second cabin plate are arranged in parallel. Mounting pieces are arranged on the first cabin plate and the second cabin plate; according to the window on the first cabin plate, the protective part can be rotated through the rotating part, so that the window can be conveniently opened and shielded, the window can be quickly closed, the time for taking and installing the protective part from other storage places is avoided, and the shielding and protecting efficiency of the window can be improved; and the window on the second cabin plate can be directly mounted on one side of the window by adopting an independent protection piece to adapt to the mounting type of the window, so that the application range of the protection piece can be expanded.
