BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a buoyancy material used for a wearable object worn on the body such as a hat or clothing, a fishing case such as a bag, a buoyant material provided with the buoyancy material, and The present invention relates to a fishing case, and particularly to a buoyancy material and a floating vest used for a floating vest.

[0002]

2. Description of the Related Art Conventionally, a floating vest of this type has a substantially plate-shaped buoyancy material made of a plastic foam on the left and right front and rear bodies.
It is common that the vest is housed in a housing space between the outer material and the lining of the vest.

On the other hand, in recent years, there has been proposed a buoyancy material which is directly fixed to the clothing of the vest by sewing or the like, and the buoyancy material itself constitutes a part of the vest. In this case, the buoyancy material is exposed to the outside. Conventionally, a jersey is adhered to a surface of a substantially plate-shaped plastic foam as a covering, and the entire plastic foam is covered with the jersey.

[0004]

However, this type of floating vest is expected to further improve the buoyancy performance, and therefore, further improvement of the buoyancy material has been demanded.

Therefore, the present invention has been made in view of the above-mentioned conventional problems, and has as its object to further improve the buoyancy performance of a buoyancy material.

[0006]

As a result of repeated studies to solve the above problems, the present inventor focused on the water absorption of the buoyancy material coating, and eliminated the water absorption of the conventional jersey, that is, The inventor has found that the use of a waterproof covering body can ensure more buoyancy performance than before, and has completed the present invention.

That is, a buoyancy material according to the present invention is characterized in that a waterproof film is adhered to the surface of a plastic foam.

Further, a waterproof film is adhered to the surface of a substantially plate-shaped plastic foam, and the plastic foam is integrally formed with the waterproof film in a thickness direction to form irregularities on the surface of the buoyancy material. Preferably, it is formed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a buoyant material and a wearable object with a buoyant material according to the present invention will be described below with reference to FIGS. A floating vest as a fishing garment provided with a buoyancy material 3 to which a bonding material 2 is adhered will be described.

The vest is composed of left and right front bodies 4, 4 and a back body 5. The back body 5 is a waist connecting body 6, which can adjust waist at left and right side portions.
At 6 it is connected to its predecessors 4,4. The entire back body 5 is composed of the buoyancy material 3. That is, the buoyancy member 3 is in a state of being exposed to the outside.

The buoyancy member 3 comprises a substantially plate-shaped plastic foam 1 and a cover 2 adhered to the plastic foam 1 so as to cover the entire surface of the plastic foam 1. That is, the outer surface 1a and the inner surface 1b of the plastic foam 1
In this case, the covering 2 is adhered over the entire surface, and the covering 2 on the outer surface 1a and that on the inner surface 1b are overlapped and fixed to each other at the peripheral edge A of the buoyant material 3.

At the side edge B of the buoyancy member 3, the two covering members 2 overlapped with each other are fixed to the waist connector 6 by sewing.

Here, as the plastic foam 1,
A foam such as an ethylene-vinyl acetate copolymer, polyvinyl chloride, or polystyrene can be used. In this embodiment, a foam of the ethylene-vinyl acetate copolymer is used.

As the cover 2 for covering the plastic foam 1, a waterproof film is employed instead of a jersey as in the prior art. Examples of the waterproof film include an ethylene vinyl acetate copolymer (EVA) film,
Polyvinyl chloride (PVC) film, polyurethane (P
U) Various known materials such as films can be employed. In particular, those that can be heat-fused with the plastic foam 1 are preferable. In the present embodiment, a polyurethane film is used.
It is bonded to the outer and inner surfaces 1a and 1b of the plastic foam 1 by heat fusion.

On the other hand, the buoyancy material 3 has a surface, especially an outer surface 1.
Predetermined irregularities are formed on the a side. That is, the outer surface 1 a of the buoyancy member 3 is provided with a plurality of convex portions 7 (thick portions) having a predetermined shape and a plurality of concave portions 8 (thin portions) having a smaller thickness than the convex portions 7. Then, as shown in FIG. 2, the thickness of the plastic foam 1 in the concave portion 8 is smaller than that of the convex portion 7. The buoyancy material 3 is easily bent at the thin recess 8, and the linear recess 8 functions as a bent portion.

As a method of giving a change to the thickness of the buoyant member 3 as described above, for example, a predetermined portion of the substantially plate-shaped plastic foam 1 having a substantially uniform thickness is shaved to reduce the thickness and the concave portion 8 is formed. Although it is possible to configure, in the present embodiment, the following method is adopted.

That is, first, a substantially plate-shaped plastic foam 1 having a substantially uniform thickness is cut into a predetermined shape, and a waterproof film is bonded to both surfaces 1a and 1b of the plastic foam 1 by heat fusion. Alternatively, the waterproof film may be first cut into a predetermined shape after being bonded by heat fusion. Of course, a waterproof film may be adhered by applying an adhesive.

Then, the plastic foam 1 to which the waterproof film is adhered is thermoformed integrally with the waterproof film in the thickness direction from the state shown by the two-dot chain line C in FIG. The predetermined irregularities are formed mainly on the outer surface 1a. That is, the plastic foam 1 is formed by a pair of upper and lower molds.
Is compressed and partially strongly compressed to form the recess 8.
Is formed, and the protrusions 7 are formed by compressing the protrusions more weakly. As described above, unevenness can be formed by providing a difference in the amount of compression during compression molding. At this time, thermoforming is performed at a higher temperature than when the waterproof film is bonded.

As described above, the unevenness is formed by integrally thermoforming with the waterproof film, so that the adhered waterproof film adheres more securely to the plastic foam 1, and in particular, even in the concave portion 8. High adhesion is obtained.

After the predetermined irregularities are formed as described above, the peripheral portion A that is overlapped and adhered is fixed to the waist connector 6 by sewing.

In such a vest, since a waterproof film is used as the covering 2 of the buoyant material 3, water absorption of the covering 2 is eliminated as compared with the conventional jersey, and the whole is covered. Therefore, water absorption of the plastic foam 1 inside can be prevented. Therefore, buoyancy performance higher than that using a jersey can be obtained. In particular, the effect is large in an environment of high humidity and high temperature.

Further, since the film is a waterproof film, there is an advantage that dirt is hardly adhered and even if adhered, it can be easily removed.

Further, by forming irregularities on the outer surface 1a and the concave portion 8 functioning as a bent portion, the buoyant material 3 can be easily bent along the concave portion 8, and in the vicinity of both shoulders, up and down, left and right, In the vicinity of the waist, it is easily bent right and left.

Therefore, when the vest is worn, the buoyant member 3 is bent up and down or left and right along the body according to the body shape of the wearer, so that high adhesion to the vest is ensured. In addition, the buoyancy material 3 is bent and deformed in accordance with the movement of the wearer, so that the vest always fits the body, and fishing can be performed without discomfort.

It is to be noted that irregularities may be provided not only on the outer surface 1a but also on the inner surface 1b. It is also possible to attach a waterproof film to only one of the outer surface 1a and the inner surface 1b, and to attach a jersey to the other, for example, as in the conventional case. In this way, a waterproof film can be partially adhered. Further, in the above description, the configuration in which the buoyant material itself is directly fixed to constitute a part of the vest has been described. Of course, it is good. In this case, since the water may enter the accommodation space from the seam or the like, the effect of the waterproof film is obtained.

Further, the present invention can be applied to fishing clothes other than the floating vest and other clothes, and can be applied to wear other than clothes such as a hat.

Also, as shown in FIG. 3, the present invention can be applied to a fishing case provided with a buoyancy material. The case has a configuration in which a predetermined portion of the case main body 20 is covered with a buoyant material 21. Even if the case is dropped into the sea or the like, the case floats on the water surface due to the buoyancy of the buoyant material 21. The buoyancy material 21
In the same manner as described above, the covering 23 made of a waterproof film is adhered to the surface of the plastic foam 22, and the buoyancy of the buoyancy material 21 is suppressed from being reduced by the waterproof effect of the waterproof film. You. Thus, the buoyancy material of the present invention can be applied to various types.

[0028]

As described above, by attaching the waterproof film to the surface of the plastic foam, the buoyancy performance can be further improved as compared with the case where the conventional jersey is attached.
