JP 2005-59465 A

  However, such conventional underwater footwear simply overlaps the foot of the footwear and the hem of the waterproof garment, so that water enters the waterproof garment or the underwater footwear from the hem. There is a problem. If water enters the inside of the waterproof garment, problems such as a decrease in heat retention occur, which is not preferable.

  The present invention has been devised in view of these problems, and an object of the present invention is to provide an underwater footwear capable of preventing water from entering the inside of a waterproof garment.

  Definition of terms: Waterproof clothing means waterproof clothing such as wet suits.

This will be described with reference to FIGS. The underwater footwear 1 according to claim 1 is a boot composed of a cylindrical trunk 10 and a footwear main body 20 that is worn together with waterproof clothing 2 when performing underwater sports such as surfing, diving or canoeing. Is. Then, at least the upper part of the body part 10 is formed in a two-layer structure in which the bottom part 12a is sealed with two cylindrical walls 11, and the hem 2a of the waterproof garment 2 is inserted between the two cylindrical walls 11. The storage portion 12 is tightly sandwiched.

  The underwater footwear 1 according to claim 2 is a boot composed of a cylindrical trunk 10 and a footwear main body 20 that is worn together with waterproof clothing 2 when performing underwater sports such as surfing, diving, or canoeing. A plurality of foam fabric pieces P that are elastic and stretchable are formed by bonding their cut surfaces F together.

  Then, at least the upper portion of the body portion 10 is formed with a two-layer structure with two cylindrical walls 11 and the bottom portion 12a is hermetically sealed by bonding the cut surfaces F, and the waterproof wall is formed between the two cylindrical walls 11. The skirt 2a of the clothes 2 was inserted into the storage portion 12 that was tightly sandwiched. In addition, the pasted portion S of at least the heel portion 24 side of the foam fabric piece P is provided below the ankle portion 13 or on the toe portion 23 side.

  The underwater footwear 1 according to claim 3 is the invention according to claim 2, in which the thickness of the cut surface F of the two cylindrical walls 11 forming the storage portion 12 having the two-layer structure is bonded to the single layer. It is set to be approximately equal to the thickness of the cut surface F of the other part of the structure.

  The underwater footwear 1 according to claim 4 is a boot composed of a cylindrical trunk 10 and a footwear main body 20 that is worn together with waterproof clothing 2 when performing underwater sports such as surfing, diving, or canoeing. A plurality of foam fabric pieces P that are elastic and stretchable are formed by bonding.

  Then, at least the upper portion of the body portion 10 is bonded to the outer cylindrical wall 11b with a tapered cut surface F formed at the lower end portion of the inner cylindrical wall 11a of the two cylindrical walls 11, and the bottom portion 12a is sealed. The storage portion 12 is formed into a two-layer structure, and the hem port 2a of the waterproof garment 2 is inserted between the two cylindrical walls 11 so as to be tightly sandwiched.

  The underwater footwear 1 according to claim 1 is composed of a cylindrical trunk portion 10 and a footwear main body portion 20, and at least an upper portion of the trunk portion 10 is formed in a two-layer structure with two cylindrical walls 11. Since the storage portion 12 is inserted between the two cylindrical walls 11 so that the hem port 2a of the waterproof clothing 2 is tightly sandwiched, water can be prevented from entering the waterproof clothing 2 and the underwater footwear 1 itself. can do.

  That is, the outer peripheral surface of the hem port 2a of the waterproof garment 2 is in close contact with the inner peripheral surface of the outer cylindrical wall 11b, and the inner peripheral surface of the hem port 2a is in close contact with the outer peripheral surface of the inner cylindrical wall 11a. Two close contact surfaces prevent the passage of water. Further, since the bottom portion 12a of the storage portion 12 is sealed, water does not enter the waterproof clothing 2 and the underwater footwear 1 from the bottom portion 12a. Thereby, invasion of water can be prevented beforehand.

  The underwater footwear 1 according to claim 2 is formed in a two-layer structure in which at least an upper portion of the trunk portion 10 is formed with two cylindrical walls 11 and a bottom portion 12a is sealed, and a waterproof clothing is provided between the two cylindrical walls 11. Since the storage portion 12 is inserted into the hem port 2a and tightly sandwiched between the hem ports 2a, water can be prevented from entering from the hem port 2a of the waterproof garment 2 for the same reason as in the first aspect of the invention. be able to.

  In addition, since the underwater footwear 1 is formed using a plurality of foam fabric pieces P having elasticity, the storage portion 12 can be brought into close contact with the hem mouth 2a of the waterproof clothing 2, thereby Even water can be prevented from entering.

  Moreover, since the storage part 12 of the two-layer structure which sealed the bottom part 12a is formed by bonding together the cut surfaces F of the several foam fabric piece P, it is strong by the characteristic which the foam fabric piece P has. Bonding can be performed. Therefore, the storage part 12 is not torn at the bonding part S, and as a result, water intrusion can be more reliably prevented.

  In addition, since not only the bottom part 12a of the storage part 12 but other bonding parts S, such as two half cylinder walls in the cylinder wall 11, can be firmly bonded, the underwater footwear having excellent durability 1 can be used.

  Further, the underwater footwear 1 is provided with a bonding portion S between the body portion 10 and the footwear main body portion 20 on the lower side or the toe portion 23 side of the ankle portion 13. This is because, as shown by X in FIG. 6, when the underwater footwear 1 is worn, the largest insertion resistance acts on the heel H of the foot, so that the inner diameter of the trunk portion 10 of the underwater footwear 1 is the largest. If the bonding portion S is provided on the small ankle portion 13, the bonding portion S is a portion that is difficult to expand and contract by the adhesive, and thus it is difficult to insert (and extract) the heel H. This is because wearing becomes extremely troublesome. By providing the bonding part S below the ankle part 13 (or on the toe part 23 side), such a situation can be avoided in advance.

  The underwater footwear 1 according to claim 3 exhibits the same effect as the invention according to claim 2. Further, since the thickness of the cut surface F of the two cylindrical walls 11 forming the storage portion 12 of the two-layer structure is set to be substantially equal to the thickness of the cut surface F of the other part of the single-layer structure to be bonded thereto, The entire cut surface F can be pasted together. Therefore, the strength of the bonded portion S can be further increased. Furthermore, since the bonded portion S between the two-layer structure portion and the single-layer structure portion can be made a smooth surface without a step, it is possible to provide excellent comfort and appearance.

  The underwater footwear 1 according to claim 4 has a tapered cut surface F formed at the lower end portion of the inner cylindrical wall 11a of the two cylindrical walls 11 at least at the upper portion of the trunk portion 10, and the outer cylindrical wall. 11b is formed into a two-layer structure in which the bottom portion 12a is sealed, and the storage portion 12 between the two cylindrical walls 11 is inserted into the bottom portion 2a of the waterproof garment 2 so as to be tightly sandwiched. Intrusion into the waterproof clothing 2 can be prevented.

  In addition, since the cut surface F of the inner cylindrical wall 11a is tapered, the area to be attached to the outer cylindrical wall 11b can be increased, and can be firmly attached. Further, since no step is formed between the inner cylindrical wall 11a and the outer cylindrical wall 11b, the appearance can be improved.

  1 to 5 show a first embodiment of an underwater footwear 1 according to the present invention. This is to be worn together with the waterproof clothing 2 when performing underwater sports such as surfing, diving, or canoeing, and has a boot shape composed of a cylindrical body 10 and a footwear main body 20. This underwater footwear 1 is formed by bonding a plurality of foam fabric pieces P, which are rich in stretchability, to each other with their cut surfaces F bonded together. For the foam dough piece P, for example, chloroprene having closed cells can be used.

  Moreover, while making the whole trunk | drum 10 into the two-layer structure formed with the two cylinder walls 11, the footwear main-body part 20 is made into the one layer structure. And between the two cylindrical walls 11, the cut surface F of the lower end is bonded to the cut surface F of the upper end of the footwear main-body part 20, and it is set as the accommodating part 12 by sealing the bottom part 12a. The storage portion 12 stores the hem opening 2a of the waterproof garment 2, and the two cylinder walls 11 tightly hold the hem opening 2a from inside and outside. Thereby, it can prevent that water penetrate | invades into the inside from the hem mouth 2a of the waterproof clothing 2. FIG.

  In addition, the footwear main-body part 20 is formed in the one layer structure by bonding the two foam fabric pieces P which form the upper part 21 and the sole part 22 together. Therefore, in order to perform good bonding with the body portion 10 having the two-layer structure, the thickness of the cut surface F of each cylindrical wall 11 is set to ½ of the thickness of the cut surface F of the footwear main body portion 20. Thus, the wall thickness of both cut sections F is made equal, and the entire cut sections F are bonded together (see FIGS. 3 and 4). Thereby, the intensity | strength of the bonding part S is raised and the improvement of durability is aimed at. In addition, by making the bonded portion S a smooth surface with no steps, the comfort and appearance are improved.

  Further, the underwater footwear 1 is provided with a bonding portion S between the trunk portion 10 and the footwear main body portion 20 below the ankle portion 13. This is because, when the underwater footwear 1 is worn, the greatest insertion resistance acts on the foot heel H. Therefore, when the bonding portion S is provided on the ankle portion 13 having a small inner diameter, the bonding portion S is bonded. This is because it becomes difficult to insert (and pull out) the eyelid because it is a portion that is difficult to expand and contract by the agent.

  As shown in FIG. 5, the underwater footwear 1 has a rubber reinforcing material R adhered to the sole 22, the toe 23, or the heel 24 on the outer side, and the necessary reinforcement is performed. This is product 1A. Further, in the final product 1A, a locking device 30 composed of a hook-and-loop tape, a band, a string, or the like is provided at the upper end portion of the storage portion 12, and by tightening the locking device 30, water is stored in the storage portion 12 and the waterproof clothing. It is preferable to more surely prevent the intrusion into the inside of 2.

  FIG. 7 shows a second embodiment of the underwater footwear 1 according to the present invention. The feature of the underwater footwear 1 is that the bonding portion S is provided not on the trunk portion 10 but on the upper portion 21 of the footwear main body portion 20. By doing so, as in the first embodiment, the resistance acting on the heel at the time of mounting (and removal) is reduced, and mounting and the like are facilitated. It should be noted that the rubber reinforcing material R is bonded to a necessary portion such as the sole 22 also in the final product of the underwater footwear 1. Moreover, the latching tool 30 can also be attached.

  8 and 9 show a third embodiment of the underwater footwear 1 according to the present invention. The feature of the underwater footwear 1 is that a taper-shaped cut surface F formed on the lower end portion of the inner cylindrical wall 11a of the two cylindrical walls 11 of the entire body 10 is formed in the outer cylindrical wall 11b. That is, it is formed in a two-layer structure in which the bottom 12a is sealed by being bonded to the peripheral surface. And between the two cylinder walls 11, it is set as the accommodating part 12 which inserts the hem port 2a of the waterproof clothing 2, and clamps tightly.

  Even with this configuration, water can be almost certainly prevented from entering the waterproof clothing 2. In addition, since the cut surface F of the inner cylindrical wall 11a is tapered, the area to be bonded to the outer cylindrical wall 11b can be increased, and strong bonding can be achieved. Furthermore, since the affixed portion between the inner cylindrical wall 11a and the outer cylindrical wall 11b can be a smooth surface without a step, the underwater footwear 1 having a good appearance can be obtained.

  In addition, since this underwater footwear 1 bonds the cut surface F of the inner cylindrical wall 11a to the inner peripheral surface of the outer cylindrical wall 11b, the bonded portion S as in the first and second embodiments is formed. Not. Moreover, it is better to provide the component part below the ankle part 13.

  The underwater footwear 1 in the first, second and third embodiments can be laminated with a stretchable fabric such as a nylon jersey on the surface of the foam fabric piece P. Thereby, durability can be improved.
