Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a life-saving device to be used as a life-saving boat in the event of ship wreck, storm or flood damage, and the like. The following description describes the case where it is used on the sea surface.

[0002]

[Prior art]

 Lifeboats (life rafts) are used as rescue tools when ships are damaged by storms or when floods are caused by heavy rain. However, conventional lifeboats have a problem that they are easily overturned due to wind, rain and waves, and cannot be easily handled by one person in an emergency.

[0003]

[Problems to be solved by the invention]

 The purpose of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to provide a life-saving boat which is light in weight, easy to handle, does not capsize when used as a boat, and does not sink. To be.

[0004]

[Means for Solving the Problems]

 The present invention provides a synthetic resin foam (1) comprising a plate-shaped or boat-shaped synthetic resin foam (1) and a rectangular parallelepiped FRP box (2) provided with a water storage cavity (3). Is a lifeboat (A 1) in which the FRP box body (2) and the FRP box body (2) are joined together up and down so that the synthetic resin foam (1) has an occupant recess on the upper surface. (B), the FRP box (2) has a plurality of water inflow holes (7) having a check valve (8) in each hole (7) in the bottom plate (5), and the side plate (4). ) Is a lifeboat characterized by having a deaeration hole (6) and a drain valve (12). When the lifeboat of the present invention floats on the sea, seawater flows into the water storage cavity (3) from a plurality of holes (7) provided in the bottom plate (5) of the FRP box (2), and the water (3). The seawater filled with water acts as a weight, and becomes a safe lifeboat without capsizing.

[0005]

[Embodiment of the invention]

 One example of a method for manufacturing a lifeboat according to the present invention will be described with reference to FIG. A plate-shaped or boat-shaped synthetic resin foam (1) is made of a foamed resin such as styrene foam, and a recess (B) for an occupant is provided on the upper surface of the plate-shaped foam (1). Separately, a rectangular box (2) having a water storage cavity (3) inside is made of a robust resin material such as FRP. The bottom plate (5) of the box (2) is provided with a plurality of holes for water inflow (7), and these holes are provided with check valves. The side plate (4) of the box (2) is provided with a deaeration hole (6) and a drain valve (12) at an appropriate place. Although the upper plate of the box body (2) is not provided in FIG. 2, the upper plate may be provided as shown in FIG. The hollow portion (3) of the box (2) may be a single large room, or may be divided into a plurality of hollow portions by a perforated partition (14). The number of cavities is not particularly limited. Considering the strength of the box (2) and the balance at the time of storing water, the partition (14) is used as appropriate. In FIG. 2, the cavity (3) is divided into three cavities. Each cavity is connected by a hole in the partition (14). Next, the synthetic resin foam (1) and the FRP box (2) shown in FIG. 2 are joined together by an adhesive or the like so as to be integrated vertically, and the lifeboat (A) of the present invention is manufactured. The number of deaeration holes (6) may be one, but a plurality is preferable. One or more drain valves (12) are provided below the side plate (4) near the bottom plate (5). The drain valve (12) is used in a closed state.

When the lifeboat of the present invention is floated on the sea, as shown in FIG. 1, seawater (9) rapidly flows through a hole (7) provided with a check valve (8) provided in the bottom plate of the box (2). The air in each of the cavities (3) and (3) finally escapes from the deaeration holes (6) through the perforated partition walls, and the cavities (3) and (3) are filled with seawater. The lifeboat (A) balances with the synthetic resin foam (1) on which the person (10) is placed to provide a safe lifeboat. The synthetic resin foam (1) may be a foam made of a copolymer mainly composed of polystyrene or a foam of a mixed resin, in addition to the foamed polystyrene alone. Since the synthetic resin foam (1) is a closed cell, it is excellent in moisture resistance, weather resistance, and corrosion resistance, and is lightweight, easy to mold, and inexpensive. Free size of synthetic resin foam (1) using Styrofoam (specific gravity 0.02 to 0.03), size of FRP box (2), volume of cavity (3), etc. according to desired weight and strength Can be used in combination. As shown in Fig. 2, when the synthetic resin foam (1) is shaped like a boat with a large semilunar floating part (13), the upper part of the lifeboat must be above the water surface like a rising spill. It has a rollover prevention effect. FIG. 3 shows a lifeboat according to the present invention in which the shape of the FRP box (2) is slightly different from that of FIG. Instead of using the upper plate, a synthetic resin foam is used to reinforce the partition wall (14) and the side plate (4). Furthermore, when the lifeboat of the present invention is used and lifted with the drain valve (12) opened, the water stored in the cavity (3) can be easily drained and easily collected. .

[0007]

[Effect of the invention]

 Since the lifeboat of the present invention is lightweight, handling in an emergency is easy. Furthermore, it is easy to manufacture and inexpensive. When floating on the sea, seawater quickly flows into the cavity (3) of the FRP box body, and the stored seawater acts as a weight and is a safe lifeboat that does not capsize due to waves.
