Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a skirt structure of an air cushion boat suitable as a high-speed freighter ship.

[Prior art]

Generally, in an air cushion boat, the lower part of the main body is surrounded by a skirt made of a flexible material to form a compartment, and high-pressure air is fed into the compartment to float, and a propulsion fan provided on the body The so-called overcraft that runs is well known.

That is, in this air cushion boat, as shown in FIGS. 3 and 4, a flexible skirt 2 made of a flexible material is arranged around the lower portion of the main body 1 to form a compartment 3 in the lower portion of the main body 1. The high pressure air is fed into the compartment 3 by the levitation fan 4 to levitate the high pressure air, and the propeller 5 for propulsion provided on the main body 1 is operated to travel.

In a relatively large-sized air cushion boat, at least the flexible skirt 2'of the bow of the flexible skirt 2 made of this flexible material is provided with a plurality of fingers at the bottom of one laterally extending air bag 6. 7 are arranged.

[Problems to be Solved by the Invention] In the skirt structure of the air cushion boat as described above, the flexible skirt 2'of the bow is provided with a plurality of fingers 7 at the bottom of one airbag 6 extending in the lateral direction of the boat. Since the air bag 6 and the fingers 7 are attached, the attachment of the airbag 6 and the fingers 7 is complicated. Air bag 6 and fingers 7
There is a problem that if the attachment is complicated, the portion may be damaged, and the weight of the airbag becomes large, so that the attachment work to the main body 1 requires a lot of time and labor.

[Means for Solving the Problems]

The present invention has been made to solve the above-mentioned problems, and in an air cushion boat having a flexible skirt on the entire circumference or the front and rear, the unit bag having an opening at the bottom and the unit bag To provide a skirt structure for an air-cushion boat in which a unit flexible skirt is composed of fingers continuously formed in the lower portion, and a plurality of unit flexible skirts are arranged in parallel laterally at least on the bow of the boat. Is.

〔Example〕

An embodiment of a skirt structure for an air cushion boat according to the present invention will be described below with reference to FIGS. 1 and 2.

FIG. 1 shows a conceptual diagram of the flexible skirt. Among them, the front flexible skirt 11 is formed by arranging the unit flexible skirts 23 composed of the unit bag 15 and the fingers 16 in parallel.

Specifically, as shown in FIG. 2, the side walls 17 are parallel to each other by the side walls 17, the front wall 18, and the rear wall 19, and the front wall 18 and the rear wall 19 are inclined obliquely downwards in front of and behind them. A unit bag 15 is formed.

An opening 20 is provided below the unit bag 15.
A finger 16 having a U-shaped cross section is connected to the lower rear portion of the unit bag 15. The fingers 16 are side walls 21 extending from both side walls 17 and the front wall 18 of the unit bag 15.
And the lower wall 22, the unit back 15 and the fingers 16 form a unit flexible skirt 23.

The unit flexible skirts 23 are arranged side by side so that the unit flexible skirts 23 are in contact with the boat body in the lateral direction as shown in FIG.

Each unit flexible skirt 23 is attached to the boat body by directly attaching the upper edge of the unit bag 15 to the lower portion of the boat body with screws or the like, and attaching the strap 24 to the lower portion of the boat body at the rear upper edge of the finger 16. It is like this.

The flexible skirt 23 shown in FIG. 2 has a strap.
24 is provided at one place, but in FIG. 1, a plurality of places are provided.

In the skirt structure of the air cushion boat having such a structure, when the levitation fan (not shown) is driven, the high pressure air is fed into the unit bag 15 from the feed hole 26 shown in FIG. 1 through the passage (not shown). The high-pressure air supplied inside blows out from the opening 20 into the finger 16,
It is sent from the fingers 16 into the compartment 14 to float the main body 1.

FIG. 2 shows an example in which the unit bag 15 does not have the field hole 26 and the upper portion thereof is open.

The main function of the unit bag 15 is to hold the shape and posture of the high-pressure air supplied to support the boat body as a holding and cushioning body for the boat underneath to protect it from the impact of waves and protect it. High-pressure air is jetted from the opening 20 at the narrow bottom to supply the high-pressure air to the fingers 16 to improve the buoyancy.

[Effect of device]

As is clear from the above description, according to the skirt structure of the air cushion boat according to the present invention, in an air cushion boat provided with a flexible skirt around the entire circumference or the front and rear, a unit bag having an opening at the bottom and the unit bag. The unit flexible skirt is composed of the fingers continuously formed in the lower part of the boat, and a plurality of unit flexible skirts are arranged side by side in the lateral direction at least on the bow of the boat, so that the following effects can be obtained.

A. Since the bag is divided into a plurality of unit bags for each unit flexible skirt, the influence of damage to the unit bag can be minimized, and the safety of the air cushion boat can be greatly improved.

B. As a result of the continuous formation of fingers at the bottom of the unit bag, the unit bag and fingers are connected at the correct position to improve the sailability and stability of the boat, and the structure is also strong, so the connection point is Hard to break.

C. By dividing the bag, the unit bag can be repaired easily, and the bag can be easily repaired, and the mounting weight can be reduced to save the mounting work.

Further, since the fingers are formed continuously on the unit bag, there is an effect that the work of attaching the unit bag and the fingers can be eliminated.
