Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an inflatable rubber boat equipped with an automatic reversing device that can reverse the hull from a capsized state and return it to a normal state.

[Conventional technology]

In an inflatable rubber boat whose bottom is made of fiber-reinforced resin reinforcement (FRP), it is labor-intensive to manually turn the hull from a capsized state and return it to a normal state. In order to reduce this labor, for example, an inflatable rubber boat with an automatic reversing device as shown in FIGS. 3 and 4 has been proposed. That is, in FIGS. 3 and 4, 1
is an inflatable rubber boat that has a bottom 2 made of FRP and has an air column 3 on the upper edge of the bottom 2 except for the stern.
A gate-shaped frame 4 is erected at the rear of the hull, an inflatable air bladder 5 is provided at the top of the frame 4, and the inflatable air bladder 5 is inflated as shown by the imaginary line in FIG. 3 to bring the hull into a capsized state. It is designed to reverse the state and return to the normal state.

[Problem that the invention attempts to solve]

However, in an inflatable rubber boat equipped with an automatic reversing device as shown in FIGS. 3 and 4, the inflatable air bladder 5 is bulky and obstructive even when not inflated, so the outboard motor 6 cannot be directly operated by the crew. It is difficult to operate the outboard motor 6, and as shown in the figure, it is necessary to remotely control the outboard motor 6 using a handle or the like, and the frame body 4 is also required, which is not desirable in terms of appearance.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a new inflatable rubber boat with an automatic reversing device that solves the above-mentioned problems in inflatable rubber boats with an automatic reversing device whose bottom is made of a fiber-reinforced resin reinforcement.

[Means for solving problems]

The present invention provides an inflatable rubber boat with a bottom made of fiber-reinforced resin reinforcing material, and is equipped with an extendable seat made by sequentially slidingly inserting a plurality of cylindrical bodies.
The innermost cylindrical body among the inserted cylindrical bodies is equipped with an automatic reversing device characterized in that an expansion air bladder is provided inside the cylindrical body that is inflated to extend the cylindrical body when the hull capsizes. The above object has been achieved by providing an inflatable rubber boat.

〔Example〕

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an inflatable rubber boat with an automatic reversing device according to the present invention shown in the drawings will be described below.

Fig. 1 is a side view schematically showing an embodiment of the present invention when the seat is raised up, with the main parts taken in section, and Fig. 2 is a side view schematically showing the main parts when the seat is retracted. In the drawings, 2 is the FRP ship bottom, and 3 shown with imaginary lines is the one shown in Figures 3 and 4.
As shown in the figure, an air column (illustrated by imaginary lines) made of rubberized cloth fixed to the upper edge of the ship's bottom 2 except for the stern and joined at the bow, 7 is formed integrally with the ship's bottom at the stern of the ship's bottom 2. With a transom that
It is constructed in the same way as a conventional inflatable rubber boat made of FRP.

Therefore, in the inflatable rubber boat with an automatic reversing device of the present invention, a stretchable seat 8 that can stand up is provided on the hull, and an inflatable air bladder 5 that allows the seat 8 to stand up when inflated is provided within the seat 8. There is.

To describe the embodiment in further detail, the seat 8
is constructed by sequentially inserting three cylindrical bodies 9 in a non-removable but slidable manner, and the outermost cylindrical body 9
The lower end of the ship is fixed to the floor plate 10, but the bottom 2
It can also be fixed directly to. In addition, the inflatable air bladder 5 installed in the seat 8 is operated by pulling a string (not shown) or detecting capsizing by a sensor (not shown), similar to the conventional inflatable rubber boat equipped with an automatic reversing device. The sensor is sensed and inflated by compressed air, and its lower end is in contact with the floorboard 10, and its upper part is fixed to the inner surface of the innermost cylindrical body 9, so that when it is inflated, the seat 8 is made to stand up as shown in FIG. Further, in FIG. 2, reference numeral 11 denotes a lid detachably provided on the upper surface of the seat 8 as a seat plate.

The material of the seat 8 is not particularly limited, but in order to maintain the upright state of the inflatable air bladder 5 and provide effective hull reversal action, it is preferable to use a rigid material, especially
FRP is preferred.

Even if the inflatable rubber boat with an automatic reversing device configured as described above becomes capsized when landing on water, etc., the inflatable rubber boat 5 is inflated as shown in FIG. Return.
Furthermore, by deflating the bookkeeping bladder 5, the inflation bladder 5 can be stored compactly within the seat 8 as shown in FIG. 2, and the inflation bladder 5 does not become bulky and become a hindrance.

[Effect of idea]

As mentioned above, the inflatable rubber boat with an automatic reversing device of the present invention has a stretchable seat that can stand up on the hull, and an inflatable air bladder that allows the seat to stand up when it is inflated. When the inflatable air sac is inflated, the hull can be reversed from a capsized state and returned to a normal state, and when the inflatable air sac is not inflated, it can be stored in the seat, so the inflatable air sac does not become bulky and get in the way. ,
Therefore, it has the practical effect of allowing the crew to directly operate the outboard motor without having to remotely control it using a steering wheel, etc., and, together with its good-looking appearance, has high practical value. .
