Description

[Detailed description of the invention] The present invention relates to dosier walls for ships.

A ship's dosier (bridge wing) is equipped with a wall for windbreak, but conventionally, the wall is fixed and is always subject to large wind pressure resistance, so when there is a headwind, the ship's propulsion resistance increases. There were problems such as an increase in

In view of the above points, the present invention aims to obtain a dosier wall for a ship that can reduce wind pressure resistance.

That is, the Dozier wall of the ship according to the present invention is
It consists of a wall body whose one end is fixed to a winding shaft in the hangar and can be rolled up and stored in the hangar, and a guide member that guides the wall body when storing and pulling out the wall body. In some cases, the wall itself can be stored inside the hangar, reducing wind pressure resistance.

An embodiment of the present invention will be described below based on the drawings. In FIG. 1, 1 is the floor of the dozier, and on the front edge of the floor 1 in the bow and stern direction,
A wall body 3 is located that is guided by a pair of upper and lower guide rails 2a and 2b as an example of a guide member. This wall body 3 has one end fixed to a winding shaft (not shown) in the hangar 4, and can be rolled up and stored in the hangar 4 by rotating the winding shaft by an input or an electric motor. It is. That is, this wall body 3 can be rolled up and is constructed, for example, from a thin iron plate or from a steel garage shutter. As shown in FIG. 2, T-shaped engagement members 5 are attached to the upper and lower ends of the wall body 3 at appropriate intervals in the length direction.
are engaged with the guide rails 2a, 2b.
Guide bars 6, 6 are provided on both sides of the wall body 3 at intermediate positions between the guide rails 2a, 2b to prevent deformation of the wall body 3 due to wind pressure. A plurality of pairs of guide bars 6, 6 may be provided between the upper and lower guide rails 2a, 2b, and they are not necessarily provided. The upper guide rail 2
A plurality of curved plate-shaped windbreakers 7 are rotatably arranged in parallel via hinges (not shown). These windbreakers 7 are the third
As shown in detail in the figure, a pair of protrusions 8, 8 are provided at the tip.
is provided in a protruding manner, and a notch 9 is formed at a position between these protrusions 8, 8. When the windbreaker 7 is rotated from the non-use position shown by the imaginary line in FIG. 1 to the use position shown by the solid line, the tip of the windbreaker 7 comes into contact with the support bar 10 and is rotatably attached to the support bar 10. A threaded rod 11 is located within the cutout 9. Then, by rotating the threaded rod 11 and turning the wing nut 12 screwed onto the threaded rod 11 to engage the protrusions 8, the windbreaker 7 is fixed in the usage position. The support bar 10 is attached to the upper guide rail 2a via a bracket (not shown). Note that 17 is a door.

In the above configuration, when the navigation wall main body 3 is not needed, it is rolled up and stored in the hangar 4, and pulled out in the direction of arrow A as shown in FIG. 1 when necessary, such as when docking. Also, similar to this, windbreaker 7
When not in use, it is kept in the non-use position, and when necessary, it is put in the use position. Incidentally, when using the dosier, the wall body 3 can be pulled out to the required position, and the windbreaker 7 can be placed in the usage position only at the required position.

In this way, since the wall body 3 can be rolled up and stored in the hangar 4, wind pressure resistance can be reduced. Further, as in this embodiment, if the windbreaker 7 can be placed in a non-use position, wind pressure resistance can be further reduced.

FIG. 4 shows another embodiment, in which a plurality of wall bodies 13 may each be drawn upward from the hangar 14. In this case,
Of course, the guide rails 15, 15 and the guide bars 16, 16 are installed in the vertical direction. Others are 1st
The configuration is similar to that of the embodiment.

As explained above, according to the dosier wall for a ship according to the present invention, since the wall main body is configured to be able to be rolled up inside the hangar, wind pressure resistance can be reduced, and therefore the propulsion resistance of the ship can be increased. The inconvenience can be solved.
