Description

[Detailed description of the invention] This invention relates to a simple float, in particular, it integrates a reinforcing band with an air supply/exhaust port and a flange for passing a rope through the float body, which has both ends of a tube made of rubber-coated cloth closed. By vulcanizing and adhering, the float is easy to handle, does not take up much storage space, and has excellent durability.

BACKGROUND ART Fenders, styrofoam, and the like have been known as conventional floats placed in fish preserves, fishing grounds, etc., or as emergency floats to prevent small fishing boats from capsizing during seine netting. However, fender floats have the drawback of being overweight and requiring effort to handle, and Styrofoam floats have the drawback of being easily damaged and lacking in durability. Since it is kept in storage, it has the disadvantage of requiring a storage space when not in use.

This invention was made to eliminate the above-mentioned drawbacks, and the purpose of this invention is to provide a float that is lightweight and easy to install and remove; The purpose is to provide a float that does not require a special storage space and has excellent durability.

That is, as shown in the embodiments and drawings described later, this invention has air supply and exhaust ports 14 made of rubber-coated cloth on the outer periphery of the float body 11, in which both ends of a tube made of rubber-coated cloth are hermetically closed.
and a reinforcing band 18 having a plurality of rope passing flanges 20 are vulcanized and bonded together, and the space provided between the reinforcing band 18 and the float body 11 is filled with foamed sponge 22. The present invention relates to a simple float 10.

Examples of this invention will be described below with reference to the drawings.

1 and 2 are a plan view and a side view, respectively, showing an embodiment of this invention.

In the above figure, reference numeral 10 indicates a float, and 11 indicates a float main body.The float main body 11 is made by overlapping both ends of a tube molded from rubber-coated cloth, covering it with a cover 12 and gluing it, and sealing it airtight. be. The rubber of the rubberized cloth is made of a material with excellent weather resistance, and the reinforcing layer is provided with one or two layers of plain woven cloth such as nylon or polyester.

Eyelet holes 13 for passing ropes are provided at both ends of the float body 11.

Further, the float main body 11 is provided with an inflating gas supply/exhaust port 14 . This supply/exhaust port 14
As shown in FIG. 3, the hose part 15 and the hakama part 1
6 are integrally molded with rubberized cloth, and the hose portion 1 is inserted into the hole 17 bored at an appropriate position in the float body 11.
The hakama portion 16 is vulcanized and bonded with the centers of the hakama portions 5 aligned.

Furthermore, reinforcing bands 18 are vulcanized and bonded to the outer periphery of the float main body 11 at a plurality of locations at appropriate intervals. This reinforcing band 18 is molded from rubberized cloth, and as shown in FIG. An eyelet hole 21 is provided for use.

FIG. 5 shows an embodiment in which the reinforcing band 18 is bonded to the float main body 11 with a space provided therebetween, and this space is filled with foamed sponge 22. In this way, the foamed sponge 22 becomes a cushioning material when the rope is passed through the eyelet hole 21 of the flange 20, and not only can the reinforcing band 18 be prevented from being worn out, but also the foamed sponge 22 can be It serves as a backup buoyancy material even if the gas leaks out.

The float 10 having the above configuration has a float main body 11
After attaching the supply/exhaust port 14 and the reinforcing band 18 to the outer periphery of the float body 11, the supply/exhaust port 14 and the reinforcing band 18 are bonded together by vulcanization, and then the cover 12 is pressed onto both ends of the float body 11. Manufactured by bonding through processing.

When using the float 10, the supply/exhaust port 14 is connected to an expansion gas source to inject gas. As the gas source for expansion, in addition to injecting air or nitrogen gas from a compressor, nitrogen gas cylinder, etc., exhaust gas from an automobile can also be injected. The normal pressure of the injection gas is 0.05Kg/ ^cm2 or less, the maximum pressure is 0.1Kg/ ^cm2
shall be.

The molded size of the float may be appropriately selected depending on the purpose of use. When not in use,
Discharge the injected gas from the supply/exhaust port, and then fold it up or roll it up in a circle starting from one end and store it.

When a float formed to a diameter of 600mm and a length of 10m is rolled up into a circle, it becomes a shape that is reduced to a diameter of 300mm and a length of about 1m. A float of this size weighs approximately 50
Since it weighs 1 kg, it can be easily carried by one person.

In addition, when manufacturing the above-mentioned float, the release cloth is sandwiched before vulcanization, and the cloth is vulcanized with an uneven surface on the surface of the float body. Checking the wear condition of the fabric grain can be used as a criterion for determining the service life.

Figures 6 and 7 show examples of the use of the float of this invention when it is attached to prevent the hull from capsizing.

In the eyelet holes 13 at both ends of the float body 11 and the eyelet holes 21 in the flange 20 of the reinforcing band 18,
The ropes 24 and 25 are passed through the ropes 24 and 25, respectively, and hung on the port side of the hull 30, and the ropes 24 at both ends of the float body 11 are moored to the mooring hook 31 on the port side, and both ends of the rope 25 passed through the flange 20 of the reinforcing band 18 are moored. The float main body 11 is then suspended by the ropes 24 and 25.
In this state, a hose 35 of a gas source (not shown) is connected to the supply/exhaust port 14, and gas is injected and expanded.

Figure 8 shows an example of the use of a float of this invention attached to a small boat for seine fishing. small boat 3
A float 10 is attached to the boat 0 in the same manner as in FIGS. 6 and 7 above, and a fishing net 40 with a float 41 attached is strung between the small boat 30 and a mother ship (not shown). 30 small boats on the mother ship side
It's starting to attract more people. The small boat 30 is
It is pulled towards the mother ship and tilts, but float 1
Since it is supported at zero, it is possible to prevent the fish caught in the fishing net 40 from escaping without capsizing.

By the way, the results of actual operations using the usage example shown in Figure 8 show that the amount of fish caught per operation was less than 100 tons when operating without using floats. By using the float of this invention, a catch of 200 tons was obtained per trip, and the number of days required for one voyage to produce the same catch was shortened from 45 days to 30 days.

In addition to being used as an emergency float for the ship's hull as shown in the above usage example, the float of this invention can also be used as an oil fence at sea by attaching a weight to the hook of the reinforcing band. It can also be used as a regular float.

As explained above, this invention consists of a tube-shaped float body made of rubber-coated cloth, with an air supply/exhaust port and a reinforcing band with a flange for passing the rope, which are vulcanized and bonded together. It is injected and used in an inflated state, and the injected gas is discharged when not in use.

Therefore, according to this invention, the entire float is lightweight, making it easy to handle, and it can be folded when not in use, but it can be rolled up into a roll and stored, so it does not require special storage space. does not require. In addition, the float of this idea has
Since there are no metal fittings attached except for the eyelet hole for passing the rope through, the float body can be used for a long period of time without being damaged, regardless of whether it is in use or not.

In addition, foamed sponge is filled between the reinforcing band and the float body, which eliminates abrasion caused by the rope on the reinforcing band, and serves as a backup buoyancy material in case the float body leaks, so it can last for a long time. It has excellent durability and can be used as a simple float with high reliability.
