Description

Boat with improved buoyancy body

Technical Field

The present invention relates to a boat with an improved buoyancy body; more particularly, the present invention relates to a boat with an improved buoyancy body, which is composed of a first coating layer and a foaming material filled in the first coating layer, and has an improved structure of the first coating layer.

Background

Patent document 1: taiwan patent publication No. M381588.

As shown in fig. 4 to 5, in patent document 1, the inventor proposed a "overturn-preventing land-based lifeboat" which is characterized in that a buoyant body 8 is composed of a cladding 81 and a foam material 82 filled in the cladding 81, and has an advantage that water inflow into the cladding or foam material leakage from the inside of the cladding is not likely to occur even if the cladding is accidentally damaged, thereby affecting buoyancy, and a boat in which the cladding of the buoyant body is filled with a foam material is referred to as a foam-filled boat 800 through many years of development.

The common foam filled boat 800 is based on a rubber boat and further modified to save many structural design costs. In addition, since the foam material 82 is filled in the coating layer 81 of the buoyant body 8, the strength of the buoyant body 8 is increased, and thus the buoyant body is further widely used in fields such as lifeboats, transportation vessels, fishing vessels, and the like.

However, the coating 81 of the common buoyancy body 8 is made of high-strength rubber or canvas along with the concept of a rubber boat, so that the strength of the buoyancy body is limited and the application in more fields is impossible. In addition, the common covering layer 81 is also made of a multi-layer composite material, however, the materials of the common covering layer 81 are fixed by adhesive, which not only has the problem that the adhesion degree is insufficient to affect the strength of the buoyant body 8, but also has the problem that the foaming temperature affects the adhesion degree of the adhesive when the foaming process is performed in the buoyant body 8.

In view of the above, the inventors of the present invention have conducted active research on the above-mentioned materials, and have conducted many years of experience in research on related products, and have conducted continuous tests and improvements to develop the present invention.

Detailed Description

In order to clearly understand the technical solution, the purpose and the effect of the present invention, a detailed description of the present invention will be described with reference to the accompanying drawings.

As shown in fig. 1 to 2, a boat 100 with an improved buoyant body of the present invention includes: a buoyancy body 1, which is substantially tubular and substantially U-shaped, and is composed of a first coating layer 11 and a foaming material 12 filled in the first coating layer 11; a bottom plate 2 arranged at the bottom of the buoyancy body 1; the tail plate 3 is arranged at the rear end of the buoyancy body 1 and the rear end of the bottom plate 2; the first coating layer 11 of the buoyant body 1 is composed of a first inner layer 111 and two first outer layers 112 coated on two sides of the first inner layer 111; the first inner layer is in a net shape; the first outer layer is sheet-shaped; with this structure, the buoyancy body 1 can have the characteristics of light weight, high strength, high friction resistance, and the like. As will be described in detail below.

Since the first coating layer 11 and the foaming material 12 constituting the buoyant body 1 have a characteristic of low specific gravity, the buoyant body 1 also has a characteristic of light weight in the case where it has a predetermined size to form a predetermined buoyancy. Further, since the foam material 12 is filled in the first coating layer 11 of the buoyant body 1, it is possible to ensure that even when the first coating layer 11 is accidentally broken, problems that affect buoyancy, such as water entering the inside of the first coating layer 11 or leakage of the foam material 12 in the first coating layer 11, are unlikely to occur.

The buoyancy body 1, the bottom plate 2 and the tail plate 3 can constitute a firm buoyancy body which can be used for carrying people or articles, for example.

As shown in fig. 2, the first coating layer 11 of the buoyant body 1 is composed of a first inner layer 111 and two first outer layers 112 coated on two sides of the first inner layer 111, and the first inner layer 111 and the first outer layers 112 can respectively adopt different configurations and different materials, so that the first coating layer has various characteristics.

The first inner layer 111 may be formed in a net shape and may be made of a material having high strength, such as steel wire, to increase the strength of the first coating layer 11.

The first outer layer 112 may be in a sheet shape and may be made of a material with high tension and high heat resistance, such as polyvinyl chloride (PVC), so as to increase the tension and heat resistance of the first coating layer 11. In addition, by the material properties of the first outer layer 112, the two first outer layers 112 can be fixed by thermal fusion bonding, and further fixed with the first inner layer 111.

In addition to the first inner layer 111 and the first outer layer 112 respectively made of different materials to improve various characteristics of the first coating layer 11, the first inner layer 111 supports the first outer layer 112, so that the friction resistance of the first outer layer 112 can be increased, and the effect of increasing the friction resistance of the first coating layer 11 can be achieved.

Figure 4 shows a perspective view of a common foam filled boat. The present invention is mainly characterized in that the first coating layer 11 of the buoyant body 1 is composed of a first inner layer 111 and two first outer layers 112 (as shown in fig. 1 to 3) coated on both sides of the first inner layer 111, and does not affect the arrangement of accessories such as safety belts, handles, paddles, etc., so that the appearance can be the same as that of a common foam-filled boat.

As shown in fig. 4-5, the common foam filled boat 800 is primarily based on the development of a rubber boat to save many structural design costs, but it is also a conceptual limitation. For example, the covering 81 of the buoyancy body 8 for public use is made of high-strength rubber or canvas along with the concept of a rubber boat.

However, the inventors of the present invention have further studied the reasons for this and found that there are two main reasons why high-strength rubber or canvas is used for the coating layer of a rubber boat in public use: 1. the coating layer needs predetermined strength and tension to bear the pressure generated by filling gas and buffer the local pressure condition when in use; 2. the cover is required to be easily folded, and after air in the cover is released, the cover is folded to be convenient to carry or store. However, the common foam filled boat 800 has no possibility of discharging the foamed material 82 for transportation or storage, and therefore, the condition for discharging the foamed material 82 in the covering layer 81 for convenient transportation or storage can be omitted; in this case, the clad layer 81 is not limited to characteristics such as the need for easy folding, and the range of usable materials becomes extremely wide, and the present invention has been developed under such circumstances. The first coating layer 11 of the buoyancy body 1 is formed by the mesh-shaped first inner layer 111 made of steel wire and the sheet-shaped first outer layer 112 made of two pieces of polyvinyl chloride, so that the limitation of inherent concepts can be overcome, and the purposes of enabling the buoyancy body 1 to have the characteristics of light weight, high strength, high friction resistance and the like are achieved.

As shown in fig. 1, a round rod-shaped anti-collision tube 4 can be arranged around the outer side of the buoyancy body 1, which not only can form an anti-collision protection structure of the buoyancy body, but also can increase the stability of the buoyancy body, and can be used as a step when a person in water climbs the buoyancy body.

As shown in fig. 3, the crash tube 4 may be composed of a second coating layer 41 and a filling material 42 filled in the second coating layer 41. In addition, the second coating layer 41 of the crash tube 4 may have the same structure as the first coating layer 11 of the buoyant body 1, that is, a second inner layer 411 made of a steel wire and a second outer layer 412 made of polyvinyl chloride and coated on both sides of the second inner layer 411, so that the crash tube 4 has the same characteristics of light weight, high strength, high friction resistance, and the like as the buoyant body 1. The two second outer layers 412 of the crash tube 4 can also be fixed by thermal fusion bonding, and further fixed together with the second inner layer 411.

The second outer layer 412 of the second coating layer 41 and the first outer layer 112 of the first coating layer 11 can be fixed together by, for example, hot melt adhesion or integral molding, so as to achieve the effects of convenient manufacturing, cost saving, and enhancing the connection strength between the crash tube 4 and the buoyant body 1.

The filling material 42 of the crash tube 4 can be a foam material, or other mixed material with a higher specific gravity can be used, so as to increase the stability of the buoyant body 1.

The above-mentioned embodiments are provided for illustrative purposes only, and should not be construed as limiting the present invention, i.e., any equivalent changes and modifications that can be made by those skilled in the art without departing from the spirit and principles of the present invention shall fall within the protection scope of the present invention.
