Abstract

PURPOSE:To enable a ship to be directly boarded and left without laying a board between the broadside of a ship and a wharf having a difference in level by providing steps along a ship side within a recess formed in a side plating and the board deck adjacent thereto. CONSTITUTION:A recess 4 formed in a side plating and the board deck 2 adjacent thereto is provided with steps arranged along the side of a small passenger ship, such as a high speed boat. Thus, directly boarding or leaving the ship is enabled for a wharf different from the broadside of the ship in height without laying a board between the broadside and the wharf. Further, the steps may be replaced by a slant surface extending along the side of the ship.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to small boat types.

When boarding and alighting, as shown in the cross-sectional view in Figure 8, a plate-shaped ladder 4 stored on the quay side is manually extended between the ship's side deck 2 and the quay wall 3 for boarding and alighting. .

However, even though such ladders are made of complementary metal and are lightweight, they require the manpower of two operators to handle them. Although the number of crew members has been reduced due to streamlining, the number of personnel required on the quay side increases personnel costs accordingly.

Therefore, if the ship is equipped with a boarding/disembarking device that does not require an operator on the quay side, this will contribute to operational profitability.

However, even if it is an automatic type, the hydraulic type used for large ships is not suitable for small ships due to the increased weight.

[Problem that the invention seeks to solve]

The present invention was proposed in view of the above circumstances, and an object of the present invention is to provide an economical small boat type that facilitates getting on and off the rock wall.

[Means for solving problems]

To this end, the present invention is characterized in that it includes a recess that is recessed across both the ship's side shell and the gunwale deck, and a slope or staircase for passengers to get on and off that is provided in the recess and extends diagonally along the ship's side. .

[For production]

With such a configuration, it is possible to obtain an economical small-sized shatter mold that facilitates getting on and off the rock wall.

〔Example〕

An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view thereof, FIG. 2, and FIG. 3.

4 and 5 are n and m in FIG. 1, respectively.

FIGS. 6 and 7 are cross-sectional views along lines IV and V, and perspective views showing modifications of FIG. 1, respectively.

First, in Figures 1 to 5, the same symbols as in Figure 8 indicate the same members as in Figure 8, 3 is the entrance door of guest room 1, 4 is
is a recessed staircase for boarding and alighting that is recessed between the side deck and the ship's side shell.

In such a structure, the cross sections of the hull at n, m, rv, and v are as shown in Figures 2, 3, 4, and 5, respectively, so the bottom step of the recess for boarding stairs ,
Since either the second tier, third tier, or the side deck is at the same level as the quay wall, it is possible to board and alight directly without having to cross the board.

As shown in FIG. 6, the recess for getting on and off the stairs can also be a sloped surface 4a with a non-slip surface treatment, as shown in FIG. It is also possible to have a structure 4b in combination with stairs.

Even in such a structure, substantially the same effects as the structure shown in FIG. 1 can be achieved.

〔Effect of the invention〕

In short, according to the present invention, there is provided a recess that is recessed across both the ship's side shell plating and the gunwale deck, and a slope or staircase for passengers that is provided in the recess and extends diagonally toward the ship's side. The present invention is extremely useful industrially because it provides an economical form of small boat that facilitates boarding and alighting on rock walls.
