On the other hand, in the sheet 5 for forming the waist, as shown in FIG. 2, the weights 8 are stacked and arranged in three layers in the recess 12 and adhered in the recess 12 by the adhesive 11. The point that the thickness of the sheet part 9 of the waist part 5 is about 8 mm while the thickness of the sheet part 9 of the ankle part sheet 6 is about 4 mm Is a length corresponding to the outer circumference of the ankle, while the length of the waist sheet 5 is a length corresponding to the outer circumference of the waist. Except for this, the two are the same, the same parts are denoted by the same reference numerals, and detailed description will be omitted.

As shown in FIGS. 1 and 2, the sheet 6 for forming the ankle and the sheet 5 for forming the waist correspond to the sheet portions 14 having substantially the same thickness as each side. The edges are adhered to each other with an adhesive (equivalent to the adhesive 11) 15 and the surfaces of the joints are sewn together with sewing threads 16 to be joined. The diving suit 28 is formed such that the seat 6 for forming the ankle portion corresponds to the portion corresponding to the ankle, and the seat 5 for forming the waist portion corresponds to the portion corresponding to the waist. .

According to the sheets 5 and 6 having the above structure, each weight 8
Is made spherical, and each weight 8 and the sheet portion (7, 9) or (7, 13) are bonded by an adhesive 11 (soft synthetic rubber), so that the weight 8 and the weight 8, The relative displacement between the weight 8 and the sheet portion (7, 9) or (7, 13) and between the weight 8 and the adhesive 11 can be easily performed, thereby making the sheets 5, 6 flexible. Properties can be imparted. Since each weight 8 has a spherical shape with a diameter of about 2 mm, unevenness due to each weight 8 is small and the surface is smooth. Therefore, in a state where the sheets 5 and 6 are bent, each weight 8 is attached to the sheet portion 9 or 13. Is relatively smooth.

According to the diving suit 28 using the seats 5 and 6, the required weight can be obtained by the weight 8, so that the conventional weight belt 2 as shown in FIG. Weights (not shown) may be unnecessary in some cases. And since it is bendable, it is easy to move the body, and since the weight 8 does not protrude from the sheets 5 and 6, it does not hinder the movement of the body. Then, by sandwiching the weight between the seat portions, a weight having a desired weight can be provided without significantly impairing the original heat retaining property of the diving suit.

Next, an example in which the seat used in the present invention is applied to a weight belt for scuba diving will be described with reference to FIGS. This weight belt 17
Can be worn when the conventional diving suit is worn, and can be worn as needed even when the diving suit 28 of the above embodiment is worn.

As shown in the external view of FIG. 6, the weight belt 17 is formed to have a length corresponding to the outer periphery of the waist, and a fastener for fastening the weight belt 17 to the waist is provided at both ends. 18 are provided.

Although the materials 25 and 26 are made of synthetic rubber, other flexible materials having flexibility may be used. Further, although the material of the weight 8 is made of lead, other materials having a relatively large specific gravity, such as copper or iron, may be used. Further, in the above-described embodiment, a large number of weights 8 having a diameter of about 2 mm are bonded to the sheet portions 7, 9,. Or the granular weight is applied to the sheet portion 7,
,... May be adhered to the corresponding portions by the adhesive 11. Further, a flat sheet is formed by mixing a powdery or granular weight with synthetic rubber or the like which is a raw material of the sheet portion.
The necessary parts of the suit 28, the weight belt 17, and the insole 22 shown in FIGS. 4, 7, and 9 may be formed.

[0033]

In the suit for scuba diving according to the present invention, since the seat is freely bendable, it can be deformed in response to a force such as bending or twisting. Since the weight is small, powdery, or granular, unevenness due to the weight is small, and therefore, the bent surface formed by the weight along the sheet portion when the sheet is bent becomes relatively smooth. Therefore, there is an effect that the required weight can be obtained by the weight, and the body is easy to move because it is bendable. Further, since the weight does not protrude from the seat portion, there is an effect that it does not hinder the movement of the body. Then, by sandwiching the weight between the seat portions, a weight having a desired weight can be provided without significantly impairing the original heat retaining property of the diving suit.

[0034]

According to the suit for scuba diving according to the second aspect of the present invention, since the sheet has the weight and the sheet portion joined by the rubber-like elastic body, the weight is combined with the weight, the weight and the sheet, and the weight and the combined body. The relative displacement between each of the rubber-like elastic bodies and the rubber-like elastic body can be easily performed, so that a desired flexibility can be imparted to the sheet.

According to the scuba diving suit according to the third aspect of the present invention, the sheet has a configuration in which small weights are stacked by a required weight and provided on the surface of the sheet portion. Can be weight. Further, since the weight can be provided in a desired number of layers, the weight can be provided on the sheet portion having a relatively small surface area. And since each small weight has a spherical shape with a diameter of about 2 mm, the bent surface formed along the sheet portion of each weight becomes relatively smooth, and it is possible to prevent the weight from being caught.

According to the scuba diving suit according to the fourth aspect of the present invention, the weight of the sheet does not protrude from the surface of the sheet portion because the weight of the sheet is held in the concave portion formed on the surface of the sheet portion. This prevents the weight from being caught or obstructed.
