Title: A wall with a splittable and moveable construction, and a vessel comprising such a wall
Inventor: RONALD VAN DIJK
IPC: B63B41/00
Filed: 2019-08-30
Abstract: This invention relates to a wall comprising a moveable construction that is moveable from and towards an opening in the wall, wherein the moveable construction comprises a splittable section and an end section connected to the splittable section. The splittable comprises a first part to be guided along a first guiding path and a second part to be guided along a second guiding path diverging from the first guiding path. As a result thereof, the moveable construction is moveable between a retracted position in which the first and second part of the splittable section are mainly arranged along the first and second guiding path, respectively, and an extended position in which the first and second part of the splittable section are mainly interlocked, such that the end section of the moveable construction is closer to the opening in the retracted position than in the extended position.
