Description

  The present invention relates to a wader worn by an angler or the like. Specifically, the present invention relates to a wader having a trouser and a boot.

  In mountain stream fishing, fishing is performed with the lower body in water. Anglers use the water to fish even for carp fishing and sea bass fishing. In these fishing, anglers wear waders. The wader is waterproof. The wader prevents the angler's body and clothes from getting wet.

  FIG. 8 is a cross-sectional view showing a part of a conventional wader 2. The wader 2 includes a trouser 4 and a boot 6. FIG. 8 shows the vicinity of the skirt 8 of the trouser 4 and the vicinity of the upper edge 10 of the boot 6. The inner peripheral surface of the hem 8 is joined to the outer peripheral surface of the boot 6 by the adhesive layer 12. The trouser 4 and the boot 6 are joined in a watertight manner. A wader 2 including a trouser 4 and a boot 6 is disclosed in Japanese Patent Application Laid-Open No. 2011-89238.

JP 2011-89238 A

  In the wader 2 having the boot 6, a non-stretchable fabric is generally used for the trouser 4. The rigidity of the trouser 4 is low. On the other hand, since the boot 6 requires strength, rubber or synthetic resin having high hardness is used for the boot 6. This boot has high rigidity. The difference in rigidity between the trouser 4 and the boot 6 is large.

  Anglers bend their knees and ankles when walking. Since the trouser 4 does not have a shape retaining property, the trouser 4 is deformed together with the angler's leg when walking. On the other hand, the boot 6 is hard and is not easily deformed. As a result, the trouser 4 is locally bent and pulled near the upper edge 10 of the boot 6. Stress concentrates on the trouser 4 in the vicinity of the upper edge 10. A hole is opened in the trouser 4 due to the stress concentration, and water enters the boot 6 from this hole. The wader 2 with a hole does not exhibit a waterproof function, so it can no longer be used.

  In fishing where the wader 2 is worn, the angler walks around a wide area in search of good points. Furthermore, the angler repeats actions such as climbing a rock and squatting. From the viewpoint of followability to these operations, the crotch of the trouser 4 is set sufficiently long. The trouser 4 may be bent at the upper edge 10 of the boot 6 and may enter between the boot 6 and the angler's shin 14 as shown in FIG. Water 16 accumulates in the space created by this intrusion. The water 16 is retained even if the angler is raised on land. The angler feels uncomfortable due to the weight of the water 16. The weight of the water 16 hinders the angler's action. The action with the water 16 accumulated will make the angler tired. If the trouser 4 is pulled up by the angler, the water 16 is discharged. However, it is troublesome for the angler to frequently perform the lifting operation.

  An object of the present invention is to provide a wader in which a hole is not easily formed in a trouser and water is not easily accumulated in a boot.

  The wader according to the present invention includes a trouser having a hem, a boot, and a reinforcing layer in which at least a part of the upper edge thereof is located above the upper edge of the boot. The vicinity of the hem is joined to the boot. The reinforcing layer is laminated on the trouser in the vicinity of the skirt. The height of the upper edge of the reinforcing layer varies along the circumferential direction of the boot.

  Preferably, the difference between the height of the highest portion P1 and the height of the lowest portion P2 of the upper edge of the reinforcing layer is 10 mm or more.

  Preferably, a part of the reinforcing layer is sandwiched between the trouser and the boot.

  The wader may further comprise a seam tape. The trouser may have a front body and a back body in the vicinity of the hem. The front body and the back body may be sewn with a thread. By covering the yarn with seam tape, watertightness between the front body and the back body can be achieved. Preferably, the highest portion P1 of the upper edge of the reinforcing layer is adjacent to the seam tape.

  In the wader according to the present invention, the rigidity in the vicinity of the skirt is enhanced by the reinforcing layer. Since the height of the upper edge of the reinforcing layer varies along the circumferential direction of the boot, the stress on the trouser is dispersed. With this trouser, it is difficult to make holes. When the trouser bends inside the boot, the space created between the boot and the angler's shin slopes along the reinforcement layer. Due to this inclination, the water that has entered the space is discharged. With this wader, it is difficult for water to collect inside the boot.

  Hereinafter, the present invention will be described in detail based on preferred embodiments with appropriate reference to the drawings.

  FIG. 1 is a perspective view showing a wader 20 according to an embodiment of the present invention. The wader 20 includes a trouser 22 and a pair of boots 24. The trouser 22 is joined to the boot 24. The trouser 22 and the boot 24 are integrated.

  2 and 3, the boot 24 is shown. The boot 24 has an outsole 26, a midsole 28, and an upper 30. Although not shown, the boot 24 also includes an insole.

  The outsole 26 is made of felt. The felt prevents the boot 24 from slipping in a wet rocky place or the like. The outsole 26 is joined to the midsole 28 by a hook-and-loop fastener (for example, “magic tape (registered trademark)”). The outsole 26 is detachable from the midsole 28. If the felt wears out, the outsole 26 can be replaced. The outsole 26 may be made of rubber or synthetic resin. The outsole 26 may include spike pins. The boot 24 may include an outsole 26 that cannot be removed from the midsole 28.

  The midsole 28 is formed by crosslinking a rubber composition. For the midsole 28, rubber having excellent strength is used. Preferred rubbers include natural rubber, polybutadiene, and styrene-butadiene copolymer.

  The upper 30 is formed by crosslinking a rubber composition. A typical base rubber of the rubber composition is natural rubber. Synthetic rubber may be used for the upper 30. The upper 30 may be molded from a synthetic resin. Specific examples of the synthetic resin include polyvinyl chloride. The upper 30 is joined to the midsole 28 by an adhesive. The upper 30 may be joined to the midsole 28 by vulcanization adhesion.

  The trouser 22 includes a butt 32, a pair of legs 34, and a pair of shoulder belts 36. The trouser 22 consists of a waterproof moisture-permeable fabric. This waterproof and moisture permeable fabric prevents water from entering from the outside and releases sweat water vapor. Steaming is suppressed by this waterproof and moisture-permeable fabric. Specific examples of waterproof and moisture-permeable fabrics include Shimano's “Dry Shield” and Gore-Tex's “GORE-TEX (registered trademark)”.

  As shown in FIG. 4, the trouser 22 has a front body 40 and a back body 42 in the vicinity of the hem 38 (that is, the leg 34). The front body 40 and the back body 42 are stitched together by a thread 44. Stitching is performed on the inside and outside of the hem 38.

  As shown in FIG. 2-5, the wader 20 further includes two seam tapes 46. Each seam tape 46 covers the thread 44. Although not shown, the seam tape 46 is composed of a base fabric and a hot melt adhesive applied to the base fabric. The base fabric is bonded to the trouser 22 by this hot melt adhesive. With the seam tape 46, watertightness between the front body 40 and the back body 42 is achieved.

  As shown in FIG. 2-5, the wader 20 further includes a reinforcing layer 48. As shown in FIGS. 3 and 4, the reinforcing layer 48 includes a first sheet 50 and a second sheet 52. The first sheet 50 is located on the toe side. The second sheet 52 is located on the heel side. The reinforcing layer 48 may consist of a single sheet. The reinforcing layer 48 may be composed of three or more sheets. For the reinforcing layer 48, a woven fabric, a nonwoven fabric, a resin sheet, a laminate of a cloth and a resin sheet, a cloth impregnated with a resin, or the like can be used. A sheet made of the same material as the seam tape 46 may be used for the reinforcing layer 48.

  As shown in FIG. 3, the vicinity of the lower end 53 of the reinforcing layer 48 is laminated with the vicinity of the upper edge 54 of the upper 30. The reinforcing layer 48 and the upper 30 are joined. Joining is achieved with an adhesive. By the joining, watertightness between the upper 30 and the reinforcing layer 48 is achieved. A portion of the reinforcing layer 48 that is not stacked with the upper 30 is located above the upper edge 54 of the upper 30. Therefore, the upper edge 56 of the reinforcing layer 48 is located above the upper edge 54 of the upper 30.

  As shown in FIG. 5, the trouser 22 is laminated with the reinforcing layer 48 in the vicinity of the skirt 38. The trouser 22 and the reinforcing layer 48 are joined. Joining is achieved with an adhesive. By the joining, watertightness between the trouser 22 and the reinforcing layer 48 is achieved. As described above, the reinforcing layer 48 is joined to the upper 30. In other words, the trouser 22 is joined to the upper 30 via the reinforcing layer 48. A part of the reinforcing layer 48 is sandwiched between the trouser 22 and the upper 30.

In FIG. 5, the region indicated by reference symbol A is a region where the trouser 22, the reinforcing layer 48 and the upper 30 are present, and the region indicated by reference character B is a region where the trouser 22 and the reinforcing layer 48 are present. An area indicated by C is an area where only the trouser 22 exists. Since the region A includes the upper 30, the rigidity Ga of the wader 20 in the region A is large. Since the region C includes only the trouser 22, the rigidity Gc of the wader 20 in the region C is small. Since the region B includes the reinforcing layer 48 in addition to the trouser 22, the rigidity Gb of the wader 20 in the region B is larger than the rigidity Gc. On the other hand, since the region B does not include the upper 30, the rigidity Gb of the wader 20 in the region B is smaller than the rigidity Ga. Between the rigidity Ga, Gb, and Gc, the relationship shown by the following mathematical formula is established.
Ga>Gb> Gc
The material and thickness of the reinforcing layer 48 are set so that an appropriate rigidity Gb is obtained.

  In this wader 20, since the rigidity Gb is moderately large, the region B is not easily collapsed. Accordingly, stress concentration on the trouser 22 is unlikely to occur at the upper edge 54 of the upper 30. The trouser 22 is difficult to open a hole. This wader 20 is long-lasting.

  FIG. 6 is a developed view showing the reinforcing layer 48 of the wader 20 of FIG. In FIG. 6, the direction (left-right direction) indicated by the arrow X is the circumferential direction of the boot 24, and the vertical direction is the height direction of the boot 24. As apparent from FIG. 6, the height of the upper edge 56 of the reinforcing layer 48 varies along the circumferential direction X. In other words, the height of the boundary between the region B (see FIG. 5) and the region C also varies along the circumferential direction X. Therefore, although the rigidity Gc is smaller than the rigidity Gb, stress concentration on the trouser 22 is unlikely to occur in the vicinity of the upper edge 56 of the reinforcing layer 48. The trouser 22 is difficult to open a hole. This wader 20 is long-lasting.

  Even if the trouser 22 is folded back at the upper edge 56 of the reinforcing layer 48 and enters the inside of the reinforcing layer 48, the height of the formed space varies along the circumferential direction X. Therefore, the water at the high position flows to the low position and is discharged from the space. In this wader 20, water is difficult to collect.

  In FIG. 6, what is indicated by a symbol P <b> 1 is the highest portion of the upper edge 56. In FIG. 6, what is indicated by a symbol P <b> 2 is the lowest portion of the upper edge 56. What is indicated by an arrow D in FIG. 6 is the difference between the height of the point P1 and the height of the point P2. From the viewpoint that stress is not easily concentrated on the trouser 22 and from the viewpoint that water is easily discharged, the difference D is preferably 10 mm or more, more preferably 20 mm or more, and particularly preferably 25 mm or more. The difference D is preferably 70 mm or less. When a part of the upper edge 56 of the reinforcing layer 48 is located below the upper edge 54 (see FIG. 3) of the upper 30, the position of the lowest portion coincides with the position of the upper edge 54 of the upper 30.

  As is clear from FIG. 6, the highest portion P <b> 1 is adjacent to the seam tape 46. Due to this adjacency, stress concentration on the point P1 is suppressed even though the height of the point P1 is large. In FIG. 6, an arrow L indicates the distance between the highest portion P <b> 1 and the seam tape 46. The distance L is preferably 20 mm or less, more preferably 10 mm or less, and particularly preferably 5 mm or less.

  FIG. 7 is a developed view showing a reinforcing layer 60 of a wader according to another embodiment of the present invention. The configuration of members other than the reinforcing layer 60 of this wader is the same as that of the wader shown in FIGS. 1-6. The reinforcing layer 60 includes a first sheet 62 and a second sheet 64. The first sheet 62 is located on the toe side. The second sheet 64 is located on the heel side. The reinforcing layer 60 may consist of a single sheet. The reinforcing layer 60 may be composed of three or more sheets. The material of the reinforcing layer 60 is the same as the material of the reinforcing layer 48 shown in FIG.

  In FIG. 7, the direction (left-right direction) indicated by the arrow X is the circumferential direction of the boot, and the vertical direction is the height direction of the boot. As is clear from FIG. 7, the height of the upper edge 66 of the reinforcing layer 60 varies along the circumferential direction X. Therefore, even in this wader, stress concentration on the trousers hardly occurs in the vicinity of the upper edge 66 of the reinforcing layer 60. This trouser is hard to open. This wader will last longer.

  Even if the trouser is folded back at the upper edge 66 of the reinforcing layer 60 and enters the inside of the reinforcing layer 60, the height of the formed space varies along the circumferential direction X. Therefore, the water at the high position flows to the low position and is discharged from the space. With this wader, water does not collect easily.

  In FIG. 7, what is indicated by reference sign P <b> 1 is the highest portion of the upper edge 66. In FIG. 7, what is indicated by a symbol P <b> 2 is the lowest portion of the upper edge 66. What is indicated by an arrow D in FIG. 7 is the difference between the height of the point P1 and the height of the point P2. The difference D is preferably 10 mm or more, more preferably 20 mm or more, and particularly preferably 25 mm or more from the viewpoint that stress is not easily concentrated on the trousers and that water is easily discharged. The difference D is preferably 70 mm or less. When a part of the upper edge 66 of the reinforcing layer 60 is located below the upper edge of the upper, the position of the lowest part coincides with the position of the upper edge of the upper.

  The wader according to the present invention can be used in various fishing grounds. This wader can also be used for applications other than fishing.
