Description

The present invention relates to a floating vest equipped with a buoyancy material for lifesaving, and a buoyancy material for use therewith.

In the floating vest, a buoyancy material made of foamed plastic or the like can be taken in and out of a storage portion formed between a front fabric and a back fabric, for example, on the right and left front bodies and the back of the back supporting the back. For example, as disclosed in FIG. 8 and Patent Document 1 and Patent Document 2, a plurality of buoyant members having a rectangular cross section are arranged so as to match the body line and are stored between the front fabric and the back fabric. . The position of the buoyancy material having a rectangular cross section is regulated by storing the buoyancy material in each section formed by stitching the front fabric and the back fabric. Alternatively, some buoyancy materials are put in advance in a partitioned bag-like storage body, and this storage body can be taken in and out of a storage portion formed between the front and back fabrics.

On the other hand, when this floating vest is worn by anglers or the like, it is easier to wear when naturally bent so that it fits from the back to the waistline, but the structure disclosed in Patent Document 1 and Patent Document 2 Then, only a plurality of buoyancy members having a rectangular cross section are inserted, and each of them can be freely moved, and the outer shape of the floating vest itself cannot be created.

In addition, if the outer shape of the floating vest is to be curved in advance so that it fits along the angler's body, a plastic mold is inserted separately, or a special and expensive fiber material is used. It was necessary to create a curved shape.

The present invention makes it possible to make the outer shape of the floating vest curved so that it can be easily worn by anglers and fits from the back to the waist by effectively utilizing the buoyancy material stored in the floating vest. Is.

The present invention is a floating vest that stores buoyancy material so that it can be put in and out at least at the back and waistline portions, and has a storage portion that stores the buoyancy material between the front fabric and the back fabric of the floating vest, And at least one of the back fabric or the front fabric has elasticity, and the buoyancy material is a vertically long plate-like body having a rectangular or trapezoidal cross-sectional shape, and the storage portion has a rectangular and trapezoidal cross-sectional shape. Three or more buoyancy materials or a combination of three or more buoyancy materials having a trapezoidal cross-sectional shape are stored in parallel, and the horizontal width of the storage portion of the floating vest is when the buoyancy materials to be stored are parallel The bottom side of three or more buoyancy members are arranged with the front fabric side, and the buoyancy material is forced into the storage portion against the stretchability of the front fabric. To store Accordingly, the floating best contour is configured to be curved shape, characterized in that.

According to the present invention, the buoyancy material, which is an indispensable component for the floating vest, is effectively used, and separately from the back of the floating vest without using a plastic mold, special and expensive fiber material, etc. And can be curved to fit the wearer. Furthermore, since the floating vest after fishing was wet with seawater etc., it was necessary to dry it on a hanger, etc., but according to the present invention, it can stand on the floor surface etc. without using a hanger.

Embodiments of the present invention will be described below with reference to the drawings. The floating vest 10 according to the present embodiment is mainly used for fishing. The floating vest 10 is a sleeveless jacket, and a back part that supports the back, a left part that is located on the left side of the back part, And a right side portion located on the right side.

Fig.1 (a) is the figure which opened the floating vest 10 and was seen from the inner side, and FIG.1 (b) is the cross-sectional schematic diagram. A storage section 20 is formed between the front fabric 11 and the back fabric 12 of the floating vest 10 so as to store the buoyancy material in a removable manner. FIG. 1 shows a state where no buoyancy material is stored.

Further, at least one of the front fabric 11 and the back fabric 12 has elasticity. Of course, both the front fabric 11 and the back fabric 12 may have elasticity. In addition, the elasticity mentioned here means expanding and contracting to such an extent that the buoyancy material can be pushed in and stored, as will be described below.

As shown in FIG. 2, the buoyancy material 21 according to the present embodiment includes a total of five buoyancy materials 21 including three buoyancy materials 21 used for the back portion and two buoyancy materials 21 used for the left and right waist portions. Is done. These five buoyancy materials are stored in a bag-shaped storage bag 30 for determining the position of each buoyancy material in advance before being stored in the storage portion 20 of the floating vest 10. The storage bag 30 is made of a mesh material, and is divided and arranged for each part into which each buoyancy material 21 is inserted. In addition, in the state inserted in this storage bag 30, each buoyancy material 21 is not especially closely_contact | adhered. The buoyancy material 21 is a plate-like material formed of foamed plastic or the like as in the conventional material, but the material is not particularly limited as long as it has a function as a buoyancy material.

The reason why the five buoyancy members 21 are used in the present embodiment is that the center of the back portion is supported by a substantially flat surface, and is configured so as to bend gradually from there to the waist, thereby fitting to the wearer's body. Because it can be. In addition, when it is desired to fit more finely to the wearer's back and waistline, the width of each buoyancy material 21 may be narrowed and the number thereof increased.

As shown in FIG. 2 (b), the cross-sectional shape of the buoyancy material 21 is a trapezoid, and the bottom side of the trapezoidal shape is arranged so as to be on the surface fabric 11 side of the floating vest. The trapezoidal shape is not particularly limited, but as schematically shown in FIG. 2C, the sum of the inclination angle α of one buoyancy material 21 and the inclination angle β of the other buoyancy material 21 in contact with the buoyancy material 21 is , Smaller than 180 degrees (α + β <180 degrees). The inclination angle is an angle formed by the base of the trapezoid and the hypotenuse (the side corresponding to the mathematical “trapezoidal leg”). The trapezoid includes a parallelogram.

1-3, the operation | movement which accommodates the buoyancy material 21 in the accommodating part of the floating vest 10 and that the floating vest 10 curves a back part and a waist part naturally by this are demonstrated.

FIG. 3A shows a state in which five buoyancy members 21 are arranged in advance in the storage bag 30 as shown in FIGS. 2A and 2B, and in this state, as described above, they are in close contact with each other. You can move freely without having to.

The five buoyancy members 21 are pushed into the storage part 20 of the floating vest 10 while being opened in the storage bag 30. The width of the storage part 20 is shown in FIG. As shown, it is formed slightly narrower than the total width of the bottom sides of the five buoyancy members 21. The storage port 25 is configured to be opened and closed with buttons, fasteners, and the like, so that the buoyancy material 21 can be inserted into and removed from the storage unit 20.

At least the back fabric 12 (or the front fabric 11) constituting the storage unit 20 of the floating vest 10 has elasticity, and the five buoyancy members 21 placed in the storage bag 30 are the back fabric 12 (or the front fabric). 11) is forcibly stowed in an enlarged manner. At this time, the elastic backing fabric 12 (or the front fabric 11) generates a compressive force in the shrinking direction, and the compressive force presses the five buoyant members 21 next to each other.

Each of the five buoyancy members that have received the compressive force has a trapezoidal cross section, and as shown in FIG. 3 (c), the hypotenuses of adjacent buoyancy members move so as to closely contact each other, as a whole. It balances with the curved shape (warped shape). Strictly speaking, the mesh material of the storage bag 30 is interposed between adjacent oblique sides.

As a result, according to the shape of the five curved buoyancy members 21, the outer shape of the floating vest 10 is also curved and shaped to follow the wearer's waist. In addition, when the stretching force of the back fabric 12 (or the front fabric 11) is too large, the close contact balance between the buoyancy members 21 may be lost, and therefore the stretching force and the inclination angle must be appropriately selected. .

As described above, since the “sledge” generated when the buoyancy material 21 is stored in the storage portion 20 creates the outer shape of the floating vest 10, the inclination angle of the buoyancy material 21 ranges from 75 degrees to 87 degrees. Appropriately, of course, but not limited to this angle. As described above, the inclination angle of the buoyancy material 21 must satisfy that the sum of the inclination angle α of one buoyancy material 21 and the inclination angle β of the other buoyancy material 21 is smaller than 180 degrees (α + β <180 degrees). is there. Considering only the ease of manufacture, the inclination angles α and β may be set to the same angle, but it is desirable to change the inclination angles α and β in various ways in order to fit the body shape more.

For example, the back of a human body is almost flat, and suddenly draws an arc around the trunk from the back to the side. Therefore, in order to connect the buoyancy material 21 along this line, as shown in FIG. 3, the inclination angle at which the central buoyancy material 21 and the left and right buoyancy materials 21 are in contact with each other is large, and the buoyancy material 21 is disposed along the waist. The inclination angle of the buoyancy material 21 may be gradually reduced.

Further, in order to form the buoyancy material 21 along the line from the shoulder to the waist of the human body, as shown in FIG. 4, the inclination angle is changed from the top to the bottom to a small angle. Just do it. For example, when the floating vest 10 is worn, on the shoulder side which is the upper side, the left side inclination angle γ ′ and the right side inclination angle θ ′ are the same angle (γ ′ = θ ′) in FIG. On the body side, which is the side, in FIG. 4B, the left side tilt angle γ and the right side tilt angle θ may be the same angle (γ = θ). At this time, the inclination angle γ (= θ) of both side surfaces on the trunk side is smaller than the inclination angle γ ′ (= θ ′) of both side surfaces on the shoulder side (that is, the inclination angle γ (= θ) <γ '(= Θ')).

In the above embodiment, an example in which the cross-sectional shapes of all five buoyancy members 21 are trapezoidal has been shown, but naturally, the buoyancy member 21 may be a combination of a rectangular cross-section and a trapezoidal cross-section. FIG. 5 shows various examples in which buoyancy materials having a rectangular cross section and a trapezoidal cross section are combined and curved. FIG. 5A shows an example in which the buoyancy material 21 located in the center of the back has a rectangular cross section, and the buoyancy material 21 located on the left and right sides thereof has a trapezoidal cross section. FIG. 5B shows an example in which the buoyancy material 21 located in the center of the back has a trapezoidal cross section, and the buoyancy material 21 located on the left and right sides thereof has a rectangular cross section. In any case, the object of the present invention can be achieved if the buoyancy material 21 having a trapezoidal shape and a rectangular cross-sectional shape arranged in parallel has a “warped shape” so as to draw an arc by the compressive force of the outer fabric 11. Can do.

FIG. 6 is a schematic diagram illustrating a state where the angler wears the floating vest 10 in which the buoyancy material 21 is inserted. The reason why the buoyant members 21 are slightly opened is that they are worn in close contact with the body of the wearer against the compressive force of the back fabric 12 (or the front fabric 11). Thus, even if each buoyancy material 21 may be separated by the movement of the wearer by wearing against the “sledge” of the buoyancy material 21, the backing fabric 12 (or the front fabric 11) is compressed. Since it returns to the original contact | adhered state by force, the adhesiveness of the floating vest 10 and a wearer becomes higher.

The “trapezoid” as the cross-sectional shape of the buoyancy material 21 described in the present invention does not mean a mathematically accurate trapezoid and is not necessary. That is, the point of the present invention is that the slant sides of a plurality of buoyant materials subjected to compressive force are brought into close contact with each other due to the stretchability of the front fabric or the back fabric of the floating vest 10 and are balanced in a curved shape (warped shape) as a whole. As shown in FIG. 7, even if there is a subtle step between the base and the hypotenuse, it functions to achieve the initial purpose. Therefore, the “trapezoidal shape” referred to in the present invention does not mean only a mathematically accurate trapezoid but also includes a substantially trapezoidal shape (strictly hexagonal) as shown in FIG. Moreover, in the shape shown in FIG. 7, the above-mentioned inclination angles mean angles formed by the base and the hypotenuse, respectively.

In addition, in embodiment of this invention demonstrated above, although the storage bag 30 which stores the buoyancy material 21 previously is limited to the function which only positions the buoyancy material 21 roughly, another method is used. The storage bag 30 has the same function (shrinkage and width) as the storage part of the floating vest, and a curved state is completed with the buoyancy material 21 pushed into the storage bag 30. One way is to make it in and out. In this case, the storage unit 20 is not restricted by the stretchability or width of the front fabric or the back fabric. However, in this method, the storage bag 30 in which the buoyancy material 21 is stored is bent and warped. Since it is in a state, the balance is poor, it becomes disjointed with a little external force, the handling is inconvenient, and the problem of taking a storage place arises, so that there remains a problem in practicality.

As described above, according to the present invention, since the buoyancy material used for the floating vest can be effectively used and the outer shape of the floating vest can be formed to be curved, it is easy to fit from the wearer's back to the waistline. Even without using a hanger or the like, it is possible to stand upright on the floor surface or the like.
