Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a skeleton member for a foldable boat such as a falto kayak boat or a falto canoe boat (hereinafter referred to as a “falto boat”).

[0002]

[Prior art]

 With the leisure boom in recent years, the palatable boat has become popular as an easy marine sport. There are two types of falto boats: a falto kayak boat with a cockpit part open on the deck part and a falto canoe boat with no deck part and an open cockpit part.

Both have a hull and a frame that supports the hull from the inside. A waterproof cloth or synthetic resin material is used for the hull. On the other hand, there are two types of frame parts, one made of wood and the other made of light alloy pipe material such as aluminum. Since the specific gravity of wood is smaller than that of water, the light alloy tubing contains air inside, so it also serves as a buoyancy body.

[0004]

[Problems to be solved by the device]

 However, the above-mentioned conventional frame part has the following problems. That is, although the conventional wooden frame part has been waterproofed to some extent, there is a possibility that it will be distorted by absorbing moisture when used for a long period of time. In addition, there is a problem that the wooden frame part will be damaged if it collides with a gravel or the like in a rapid flow. Further, there is a problem that the weight is slightly increased.

[0005] Furthermore, the frame portion using the pipe material made of light alloy is easy to process and can be configured to be lightweight, and there is no problem such as distortion due to absorption of water, but once water enters inside, It no longer fulfills its role as a buoyancy body. Moreover, it is almost impossible to restore the original shape by deforming it when it collides with a crushed stone. Another problem is that it is less tenacious than the wooden frame, which also has a subtle effect on the maneuverability of the paltboat.

The present invention has been made in view of the above circumstances, and does not have the problems of the frame frame members such as the conventional wooden and light alloy pipe members, that is, it can keep water even if it is used for a long time. It is an object of the present invention to provide a frame material for a paltboat that does not generate distortion due to absorption and is not damaged by impact, and that always functions as a buoyant body.

[0007]

[Means for Solving the Problems]

 The frame material of the falt boat according to the present invention is a pipe material formed of a material that does not absorb water, and a synthetic resin having a specific gravity smaller than that of water is sealed and filled.

In addition, the frame material of the flute boat according to the present invention has an outer pipe member and an inner pipe member that is inserted into the outer pipe member, and the inner surface of the outer pipe member is in close contact with the outer surface of the inner pipe member. Both pipes are made of a material that does not absorb water.

Further, the frame material of the faltic boat according to the present invention has an outer pipe member and an inner pipe member inserted into the outer pipe member, and the outer surface of the inner pipe member is closely attached to the inner surface of the outer pipe member. The inner pipe is filled with a synthetic resin that has a smaller specific gravity than water.

【Example】

 FIG. 1 is a schematic cross-sectional view of a frame material for a palatable boat according to a first embodiment of the present invention, FIG. 2 is a schematic cross-sectional view of a frame material for a paltboat according to a second embodiment of the present invention, and FIG. FIG. 6 is a schematic cross-sectional view of a frame member of a faltic boat according to a second embodiment of the invention.

As shown in FIG. 1, the frame material 100 of the paltboat according to the first embodiment has a pipe material 110 in which a synthetic resin 120 having a smaller specific gravity than water is sealed and filled.

The pipe material 110 is preferably made of a material that does not absorb water, such as a light alloy such as aluminum or a lightweight and highly rigid material such as glass fiber, carbon fiber, amorphous, or aramid fiber material. The pipe member 110 has a diameter of about 20 mm, and a joint member 130 for connecting to another frame member 100 is fitted at one end thereof.

The joint member 130 is a hollow pipe member, and the outer diameter thereof is substantially equal to the inner diameter of the pipe member 110. Therefore, the joint member 130 is attached to the pipe member 110 by fitting the joint member 130 into the pipe member 110 in a state where about half of the length thereof is projected to the outside of the pipe member 110.

On the other hand, a space 140 into which the joint member 130 of another frame member 110 is fitted is formed at the other end of the pipe member 110.

Since the synthetic resin 120 always causes the framework 100 to function as a buoyant body, it must have a specific gravity smaller than that of water. For example, urethane foam resin and polyethylene are suitable. Here, if the synthetic resin 120 has a foaming property, the sealing and filling in the pipe material can be performed at the same time as the foaming, so that the productivity is excellent. Further, if the synthetic resin 120 has a foaming property, the skeleton member 100 can be made light in weight as a whole, so that the performance as a buoyancy body is improved.

The synthetic resin 120 is not filled or filled in the entire tubular material 110, but is not filled or filled in the side where the joint member 130 is not fitted. This is because it is necessary to secure a space 140 into which the joint member 130 of the other frame member 100 is fitted.

Here, since the synthetic resin 120 is also sealed and filled in the joint member 130, when the frame member 100 is connected, the space 140 is the same as that filled and filled with the synthetic resin 120. .

Here, it is desirable that the synthetic resin 120 has a specific gravity smaller than that of water, and that the frame material 100 obtained by enclosing and filling the synthetic resin 120 in the pipe material 110 has a specific gravity smaller than that of water. The material of the pipe material 110 and the material of the synthetic resin 120 should be selected in consideration of this point.

If the air holes 150 are provided in the pipe material 110 around the space 140, air can easily escape from the air holes 150 when connecting the framework member 100. Even if the air hole 150 is opened in this way, for example, if the joint member 130 of the frame member 100 is inserted into the space 140, the air hole 150 is closed by the joint member 130, so that water enters from here. There is no fear.

Further, in the above-described first embodiment, the joint member 130 is provided on one side of the pipe member 110, and the space 140 into which the joint member 130 of the other frame member 100 is fitted is provided on the other side. Although described, the present invention is not limited to this. For example, both ends may be formed of the joint member 130, or conversely, both ends may be configured as the space 140.

Next, with reference to FIG. 2, a frame 200 of a paltboat according to a second embodiment will be described. The frame member 200 of the flute boat according to the second embodiment has an outer pipe member 210 and an inner pipe member 220 inserted into the outer pipe member 210, and an inner surface 211 of the outer pipe member 210 and an outer surface of the inner pipe member 220. 221 is closely attached.

For the outer pipe member 210, a material that does not absorb water, for example, a light alloy such as aluminum or a lightweight and highly rigid material such as glass fiber, carbon fiber, amorphous, or aramid fiber material is suitable. It is set to about 20 mm. On the other hand, the inner pipe member 220 is also made of the same material as the outer pipe member 210.

Here, the outer pipe member 210 and the inner pipe member 220 are set to have substantially the same length dimension. One end side of the inner pipe member 220 serves as a joint portion 222 and projects from one end side of the outer pipe member 210.

Here, if the lengths of the outer pipe member 210 and the inner pipe member 220 are set to be equal, the side of the joint part 222 opposite to the side where the inner pipe member 220 projects is a joint of another frame member 200. It can be configured as a space 230 into which the portion 222 is inserted.

Further, if the components of the outer pipe member 210 and the inner pipe member 220 are made different, the toughness is further increased. For example, it is applicable that the outer pipe 210 is made of aluminum and the inner pipe 220 is made of carbon fiber. Further, even when aluminum is used for both the outer pipe member 210 and the inner pipe member 220, the fact that the numbers are different corresponds to this.

Further, in the above-described second embodiment, the joint portion 222 is provided on one side of the frame member 200, and the space 230 into which the joint portion 222 of the other frame member 200 is fitted is provided on the other side. However, the present invention is not limited to this. For example, both ends may be formed of the joint portion 222, or conversely, both ends may be formed as the space 230.

Next, a skeleton member 300 of the paltboat according to the third embodiment will be described with reference to FIG. The skeleton member 300 of the flute boat according to the third embodiment has an outer pipe member 310 and an inner pipe member 320 to be inserted into the outer pipe member 310, and an inner surface 311 of the outer pipe member 310 and an outer surface of the inner pipe member 320. 321 is in close contact, and the inner pipe member 320 is filled with and filled with a synthetic resin 330 having a specific gravity smaller than that of water.

For the outer pipe member 310, a material that does not absorb water, such as a light alloy such as aluminum, a glass fiber, a carbon fiber, an amorphous material, or a aramid fiber material, which is lightweight and has high rigidity, is suitable. It is set to about 20 mm. On the other hand, the inner pipe member 320 is also made of the same material as the outer pipe member 310.

Here, the outer pipe member 310 and the inner pipe member 320 are set to have substantially the same length dimension. One end side of the inner pipe member 320 serves as a joint portion 322 and projects from one end side of the outer pipe member 310.

If the lengths of the outer pipe member 310 and the inner pipe member 320 are set equal to each other, the side of the joint portion 322 opposite to the side where the inner pipe member 320 protrudes is a joint of another frame member 300. It can be configured as a space 330 into which the portion 322 is inserted.

Further, if the components of the outer pipe member 210 and the inner pipe member 220 are made different, the toughness is further increased. This is as described in the second embodiment.

The synthetic resin 340 filled and filled in the inner pipe member 320 always causes the skeleton member 300 to serve as a buoyant body, and therefore must have a specific gravity smaller than that of water. For example, urethane foam resin and polyethylene are suitable. Here, if the synthetic resin 340 is foamable, the inner tube 320 can be sealed and filled at the same time as the foaming, so that the productivity is excellent. Further, if the synthetic resin 340 has a foaming property, the frame member 300 can be made lightweight as a whole, and the performance as a buoyancy body is improved.

The synthetic resin 340 is enclosed and filled in the entire inner pipe member 340. That is, the synthetic resin 340 is not enclosed or filled in the space 330. This is because it is necessary to secure the space 140 into which the joint portion 322 of the other frame member 300 is fitted.

Here, since the synthetic resin 340 is also sealed and filled in the joint portion 322, if the frame member 300 is connected to another frame member 300, the space 330 is also filled and filled with the synthetic resin 340. It will be the same as what was done.

Here, the synthetic resin 340 has a smaller specific gravity than water, and the skeleton member 300 obtained by enclosing and filling the synthetic resin 340 in the inner pipe member 320 has a smaller specific gravity than water. Desirably, the materials of the outer pipe member 310, the inner pipe member 320 and the synthetic resin 340 should be selected in consideration of this point.

If the air holes 350 are provided in the outer pipe member 310 around the space 330, air can easily escape from the air holes 350 when the frame member 300 is connected. Even if the air hole 350 is opened in this way, for example, if the joint part 322 of the frame member 300 is inserted into the space 330, the air hole 350 is closed by the joint part 322, so that water enters from here. There is no fear.

[Effect of device]

 The frame material of the falt boat according to the present invention is a tube material formed of a material that does not absorb water, and a synthetic resin having a smaller specific gravity than water is sealed and filled. For this reason, water does not enter the inside of the pipe material and can always serve as a buoyancy body. In addition, the pipe material is less likely to be deformed due to the synthetic resin filled and filled even if an impact is applied from the outside. Further, since the rigidity of the entire frame material of the paltboat is improved, it is more tenacious than the frame material made of a simple hollow pipe material, and direct maneuverability of the paltboat can be secured. Furthermore, since the pipe material does not absorb water, distortion due to absorption of water does not occur even after long-term use.

Further, if the synthetic resin has a foaming property, the synthetic resin can be easily enclosed and filled, so that it can be used as a skeleton material for a paltboat excellent in terms of productivity. it can. Further, if the synthetic resin has foaming properties, the frame member can be made lightweight as a whole, so that the performance as a buoyancy body is improved.

Further, as long as the frame material of the falt boat has an outer pipe member and an inner pipe member inserted into the outer pipe member, and the outer surface of the inner pipe member is in close contact with the inner surface of the outer pipe member, Even if a shock is applied from the inside, the entire pipe is less likely to be deformed due to the inner pipe inserted into the outer pipe. Further, since the rigidity of the entire frame material of the paltboat is improved, it is more tenacious than the frame material composed of only one hollow pipe material, and the maneuverability of the direct paltboat can be secured. Furthermore, since both of the pipe materials do not absorb water, distortion due to absorption of water does not occur even after long-term use.

Further, if the components constituting the raw material are made different between the outer pipe member and the inner pipe member, the toughness is further increased and the maneuverability of the paltboat is improved.

On the other hand, in the frame material having the outer pipe member and the inner pipe member inserted into the outer pipe member, when the inner pipe member is filled with and filled with a synthetic resin having a smaller specific gravity than water, the inner pipe member inserted into the outer pipe member is filled. And because of the synthetic resin filled and filled in this inner pipe material, the toughness is increased and the maneuverability of the paltboat is improved. Further, since both of the pipe materials do not absorb water, distortion does not occur due to absorption of water even if they are used for a long period of time, as in the case described above.
