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. 5 is a sectional view showing a part of a conventional wader 2 together with a shin 4 of a human body. The wader 2 includes a trouser 6 and a boot 8. FIG. 5 shows the vicinity of the skirt 10 of the trouser 6 and the vicinity of the upper edge 12 of the boot 8. The inner peripheral surface of the hem 10 is joined to the outer peripheral surface of the boot 8 by an adhesive 14. The trouser 6 and the boot 8 are joined in a watertight manner. A wader 2 including a trouser 6 and a boot 8 is disclosed in Japanese Patent Application Laid-Open No. 2004-162225.

JP 2004-162225 A

  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. In the wader 2 having the boot 8, a non-stretchable fabric is generally used for the trouser 6. This fabric is difficult to follow the movement of the leg of the angler. From the viewpoint of followability to the operation, the crotch of the trouser 6 is set sufficiently long.

  Since the boot 8 requires strength, rubber having high hardness is used for the boot 8. On the other hand, the trouser 6 is flexible. The difference in rigidity between the trouser 6 and the boot 8 is large. Coupled with the long crotch of the trouser 6, the trouser 6 bends at the upper edge 12 of the boot 8 and enters between the boot 8 and the shin 4. As shown in FIG. 5, water 16 enters the space generated by this intrusion. Garbage may accumulate in this space.

  Anglers bend their knees and ankles when walking. Since the trouser 6 does not have shape retention, the trouser 6 is deformed together with the legs of the angler during walking. On the other hand, the boot 8 is hard and is not easily deformed. As a result, the trouser 6 is locally bent and pulled near the upper edge 12 of the boot 8. Stress concentrates on the trouser 6 in the vicinity of the upper edge 12. A hole is opened in the trouser 6 due to the stress concentration, and water enters the boot 8 from this hole. The wader 2 with a hole does not exhibit a waterproof function, so it can no longer be used.

  An object of the present invention is to provide a wader in which a trouser is unlikely to enter a boot and a trouser is difficult to open a hole.

  The wader according to the present invention includes a trouser having a hem, a boot having an upper edge, and a reinforcing layer. The vicinity of the hem is joined to the vicinity of the upper edge. The reinforcing layer is laminated on the inner surface of the trouser in the vicinity of the skirt. All or part of the reinforcing layer is located above the upper edge.

  The trouser can comprise a fabric and a coating layer laminated to the inner surface of the fabric. Preferably, the base material of the coating layer is a thermoplastic resin, and the base material of the reinforcing layer is also a thermoplastic resin. The reinforcing layer is heat-sealed to the trouser.

  The reinforcing layer may include a fabric and a coating layer laminated on the outer surface of the fabric. Preferably, the substrate of the coating layer is a thermoplastic resin. The reinforcing layer is heat-sealed to the trouser.

  In the wader according to the present invention, the rigidity in the vicinity of the skirt is enhanced by the reinforcing layer. Therefore, the trouser does not enter the boot. With this wader, water and dust are unlikely to collect at the hem. Because the reinforcement layer avoids stress concentration, it is difficult to make holes in the trousers. This wader is excellent in durability.

FIG. 1 is a perspective view illustrating a wader according to an embodiment of the present invention. FIG. 2 is an enlarged cross-sectional view showing a part of the wader of FIG. FIG. 3 is a cross-sectional view illustrating a part of a wader according to another embodiment of the present invention. FIG. 4 is a cross-sectional view illustrating a part of a wader according to still another embodiment of the present invention. FIG. 5 is a cross-sectional view showing a part of a conventional wader.

  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. The trouser 22 includes a butt portion 26, a pair of leg portions 28, and a pair of shoulder belts 30.

  A part of the leg portion 28 is shown in FIG. As shown in FIG. 2, the trouser 22 includes a fabric 30 and a coating layer 32. The fabric 30 is made of yarn. From the viewpoints of wear resistance, comfort, and the like, a fabric 30 made of nylon yarn is preferable. The coating layer 32 is made of a thermoplastic resin composition. Polyvinyl chloride is mentioned as base resin of this composition part. Polyurethane may be used as the base resin. The trouser 22 may be made of a waterproof / breathable 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. 2, the boot 24 includes an outsole 34, a midsole 36, an upper 38, a lining 40 and a retaining ring 42. Although not shown, the boot 24 also includes an insole.

  The outsole 34 is made of felt. The felt prevents the boot 24 from slipping in a wet rocky place or the like. The outsole 34 is joined to the midsole 36 by a hook-and-loop fastener (for example, “magic tape (registered trademark)”). The outsole 34 is detachable from the midsole 36. If the felt wears out, the outsole 34 can be replaced. The outsole 34 may be made of rubber or synthetic resin. The outsole 34 may include a spike pin. The boot 24 may include an outsole 34 that cannot be removed from the midsole 36.

  The midsole 36 is formed by crosslinking a rubber composition. For the midsole 36, rubber having excellent strength is used. Preferred rubbers include natural rubber, polybutadiene, and styrene-butadiene copolymer.

  The upper 38 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 38. The upper 38 may be molded from a synthetic resin. Specific examples of the synthetic resin include polyvinyl chloride. The upper 38 is joined to the midsole 36 by an adhesive. The upper 38 may be joined to the midsole 36 by vulcanization adhesion.

  The lining 40 is made of woven fabric. The lining 40 is affixed to the inner surface of the upper 38. The lining 40 reduces the coefficient of friction when the angler attaches / detaches the waders 20. The lining 40 also contributes to comfort.

  The retaining ring 42 is made of the same material as the upper 38. The stop ring 42 is wound around the upper edge 44 of the upper 38. The vicinity of the lower end 46 of the retaining ring 42 is joined to the upper 38. Typically, the retaining ring 42 is joined to the upper 38 by vulcanization adhesion. The retaining ring 42 may be joined to the upper 38 by an adhesive. The vicinity of the upper end 48 of the retaining ring 42 is not joined to the upper 38.

  As shown in FIG. 2, the skirt 50 of the trouser 22 is located in the gap between the upper 38 and the retaining ring 42. The outer surface of the hem 50 (that is, the outer surface of the fabric 30) is joined to the inner surface of the retaining ring 42 with an adhesive (not shown). The inner surface of the skirt 50 (that is, the inner surface of the coating layer 32) is joined to the outer surface of the upper 38 with an adhesive (not shown). With the adhesive, the vicinity of the skirt 50 of the trouser 22 is joined to the vicinity of the upper edge 44 of the boot 24 in a watertight manner.

  The wader 20 further includes a reinforcing layer 52. The reinforcing layer 52 has a tape shape. The reinforcing layer 52 is laminated on the inner surface of the trouser 22 (that is, the inner surface of the coating layer 32). The reinforcing layer 52 is located in the vicinity of the skirt 50. The reinforcing layer 52 is located above the upper edge 44. The reinforcing layer 52 is made of a resin composition. The base material of this composition is a thermoplastic resin.

  The reinforcing layer 52 can be laminated with the trouser 22 by heat sealing. From the viewpoint of the close contact between the trouser 22 and the reinforcing layer 52, the base resin of the coating layer 32 and the base resin of the reinforcing layer 52 are preferably the same. For example, when the base resin of the coating layer 32 is polyvinyl chloride, the base resin of the reinforcing layer 52 is preferably polyvinyl chloride. When the base resin of the coating layer 32 is polyurethane, the base resin of the reinforcing layer 52 is preferably polyurethane. The reinforcing layer 52 may be joined to the trouser 22 by an adhesive.

In FIG. 2, the region indicated by the arrow A is a region below the upper edge 44, and the region indicated by the arrow B is a region above the upper edge 44 and where the reinforcing layer 52 exists. The region indicated by arrow C is a region above the reinforcing layer 52. Since the region A includes the upper 38, 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 52 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 38, the rigidity Gb of the wader 20 in the region B is larger 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 52 are set so that an appropriate rigidity Gb is obtained. In the case of the reinforcing layer 52 made of polyvinyl chloride or polyurethane, the thickness is preferably 0.1 mm or more and 2.0 mm or less.

  In this wader 20, since the rigidity Gb is moderately large, the region B stands up firmly. Therefore, the trouser 22 does not enter the boot 24. Since the rigidity Gb is not excessive, the trouser 22 in the region C does not enter the reinforcing layer 52. In this wader 20, water and garbage do not collect. In addition, since stress does not concentrate in the vicinity of the skirt 50, it is difficult to open a hole in the trouser 22. This wader 20 is long-lasting.

  In FIG. 2, an arrow H indicates the height from the upper edge 44 of the boot 24 to the upper end 54 of the reinforcing layer 52. From the viewpoint of suppressing the intrusion of the trouser 22 into the boot 24, the height H is preferably 5 mm or more, and particularly preferably 10 mm or more. From the viewpoint of comfort, the height H is preferably 200 mm or less.

  In the wader 20, a reinforcing layer 52 is provided over the entire circumference of the leg portion 28 of the trouser 22. A reinforcing layer 52 may be provided in a part of the circumferential direction.

  FIG. 3 is a sectional view showing a part of a wader 56 according to another embodiment of the present invention. The wader 56 includes a trouser 58, a boot 60, and a reinforcing layer 62. The trouser 58 includes a fabric 64 and a coating layer 66. The materials of the fabric 64 and the coating layer 66 are the same as the materials of the fabric 30 and the coating layer 32 shown in FIG. 2, respectively. The boot 60 includes an upper 68 and a retaining ring 70. The materials of the upper 68 and the retaining ring 70 are the same as the materials of the upper 38 and the retaining ring 42 shown in FIG. The material of the reinforcing layer 62 is the same as the material of the reinforcing layer 52 shown in FIG. The reinforcing layer 62 is heat-sealed to the trouser 58.

  In this wader 56, the lower end of the reinforcing layer 62 is located between the upper 68 and the retaining ring 70. A part of the reinforcing layer 62 is located below the upper edge 72 of the upper 68, and the other part is located above the upper edge 72.

  In the wader 56, the reinforcing layer 62 increases the rigidity of the region B. Therefore, the trouser 58 does not enter the boot 60. In addition, since the stress is not concentrated, it is difficult to make a hole in the trouser 58.

  FIG. 4 is a cross-sectional view showing a part of a wader 74 according to still another embodiment of the present invention. The wader 74 includes a trouser 76, a boot 78, and a reinforcing layer 80. The trouser 76 includes a fabric 82 and a coating layer 84. The material of the fabric 82 and the coating layer 84 is the same as that of the fabric 30 and the coating layer 32 shown in FIG. The boot 78 includes an upper 86 and a retaining ring 88. The materials of the upper 86 and the retaining ring 88 are the same as the materials of the upper 38 and the retaining ring 42 shown in FIG. The reinforcing layer 80 includes a fabric 90 and a coating layer 92. The material of the fabric 90 is the same as the material of the fabric 82. The material of the coating layer 92 is the same as the material of the coating layer 84. The reinforcing layer 80 is heat-sealed to the trouser 76.

  In this wader 74, the lower end of the reinforcing layer 80 is located between the upper 86 and the retaining ring 88. A part of the reinforcing layer 80 is located below the upper edge 94 of the upper 86, and the other part is located above the upper edge 94.

  In the wader 74, the reinforcing layer 80 increases the rigidity of the region B. Accordingly, the trouser 76 does not enter the boot 78. In addition, since stress is not concentrated, it is difficult to open a hole in the trouser 76. The reinforcing layer may be composed of three or more layers.

  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.
