Hatch equipped with at least one locking socket capable of being actuated on each side of the hatch

1. A hatch comprising:

at least one socket slidingly mounted and capable of occupying an extracted locking position as well as a retracted unlocking position,

at least one flexible linear pulling member for said socket, a first member end of said pulling member being secured to said socket, said first member end being configured to move said socket from said extracted locking position to said retracted unlocking position when said first member end is urged in an unlocking direction,

a first actuation means for moving said flexible linear pulling member in the unlocking direction, by abutting against a stop member secured to said flexible linear pulling member, at a distance from a second member end opposite said first member end, and said first actuation means being controllable from a first side of said hatch,

a second actuation means for moving said flexible linear pulling member in the unlocking direction, wherein said second actuation means is connected to said second member end, and said second actuation means being controllable from a second side of said hatch, opposite said first side,

wherein said first actuation means includes a pivoting lever with a contact end capable of abutting against said stop member secured to said flexible linear member, and with a gripping end accessible from said first side of said hatch,

wherein said first actuation means is configured such that said flexible linear pulling member, by rotating said pivoting lever, is urged by moving said gripping end away from a first external surface of the hatch, located on said first side of the hatch,

wherein, in a resting position, said pivoting lever is flush with said first external surface of the hatch, and

further comprising an internal space for access to said gripping end of said pivoting lever said internal access space being closed by a hinged cover flush with said first external surface of the hatch and said pivoting lever.

2. A hatch according to claim 1 , wherein said flexible linear pulling member for said socket is a flexible cable, a chain or a rope.

3. A hatch according to claim 1 , comprising a plurality of locking sockets arranged to be movable simultaneously from said extracted locking position to said retracted unlocking position, when any one of the first and second actuation means is actuated.

4. A hatch according to claim 1 , wherein each locking socket is equipped with its own main actuation system enabling its movement from said extracted locking position to said retracted unlocking position, with said first and second actuation means forming an emergency device.

5. A hatch according to claim 4 , wherein said main actuation system is an electromagnetic system.

6. A hatch according to claim 1 , wherein each socket is also equipped with resilient return means for returning the socket to its extracted locking position.

7. A hatch according to claim 1 , wherein each locking socket is equipped at one end with a roller.

8. A hatch according to claim 1 , comprising a system for opening/closing said hatch.

9. A hatch according to claim 8 , wherein said opening/closing system comprises a cylinder system including a cylinder element provided with a cylinder into which a piston, with an external end, slides, said cylinder is equipped with first stop means,

wherein said opening/closing system also includes:

a body arranged around said cylinder element and pivotably mounted on said external end of the piston, according to a pivot axis, which body comprises second stop means and is capable of occupying, with respect to the cylinder element and according to the pivot axis, a first angular position allowing an extraction/retraction of the piston with respect to the cylinder, as well as a second angular position allowed only when the piston occupies, with respect to the cylinder, an extracted position so that said second stop means are located beyond said first stop means in a direction of extraction of the piston with respect to the cylinder, and the body occupies said second position ensuring the positioning, in the direction of extraction, opposite the first and second stop means; and

an electromagnetic attraction/repulsion device including a first element securely mounted on said cylinder as well as a second element securely mounted on said body, said electromagnetic attraction/repulsion device is designed to ensure the movement of the body from said first position to said second position, and vice versa, by attraction/repulsion of said first and second elements.

10. An aircraft including at least one hatch according to claim 1 .

11. A hatch comprising:

at least one socket slidingly mounted and capable of occupying an extracted locking position as well as a retracted unlocking position,

at least one flexible linear pulling member for said socket, a first member end of said pulling member being secured to said socket, said first member end being configured to move said socket from said extracted locking position to said retracted unlocking position when said first member end is urged in an unlocking direction,

a first actuation means for moving said flexible linear pulling member in the unlocking direction, by abutting against a stop member secured to said flexible linear pulling member, at a distance from a second member end opposite said first member end, and said first actuation means being controllable from a first side of said hatch,

a second actuation means for moving said flexible linear pulling member in the unlocking direction, wherein said second actuation means is connected to said second member end, and said second actuation means being controllable from a second side of said hatch, opposite said first side,

wherein said second actuation means includes:

an actuation push button accessible from said second side of said hatch;

a connecting link pivotably connected at a first end of the connecting link to a pin of said actuation push button; and

a sliding member pivotably connected at a first end of said sliding member to a second end of the connecting link, and connected at a second end of said sliding member to said flexible linear pulling member,

wherein said second actuation means is designed so that a pressure on said push button causes a movement of said sliding member in said unlocking direction.
