Description

  The present invention relates to footwear worn by anglers.

  The fishing footwear includes an upper and a sole. The sole is joined to the bottom of the upper. An adhesive is used for joining. A typical adhesive is based on polyurethane.

  In sea fishing, waves may hit the footwear, and seawater may enter the footwear. When fishing in rainy weather, rainwater may enter the footwear. The ingress of water makes the angler uncomfortable.

On page 197 of “2005 Fishing Tackle Catalog” issued by Shimano Co., Ltd., there are disclosed fishing footwear in which Gore-Tex (registered trademark) booties are housed in the upper. Since this bootie is waterproof, it prevents water from entering. This booty is permeable to moisture, so it is hard to get stuffy in this shoe. For convenience of manufacturing, after the booties are accommodated in the upper, the upper is joined to the sole.

  The adhesive deteriorates with time. The sole may peel from the upper due to deterioration. In sea fishing, footwear often gets wet with seawater. The deterioration of the adhesive is promoted by the salt contained in the seawater. In particular, when an adhesive based on polyurethane is exposed to seawater, severe degradation occurs due to hydrolysis.

  As the footwear wears on the sole or the upper is damaged due to repeated use, the footwear reaches its end of life. If it is normal use frequency, a sole will not peel by the lifetime. However, when the usage frequency is very low and the product is often left wet with seawater, the sole may be peeled off from the upper even though wear or damage has not progressed. When the sole is detached from the upper at the fishing spot, the angler cannot continue fishing and has difficulty in moving the place.

  When the upper and the sole are stitched together, the detachment of the sole does not occur. However, the stitching creates a hole in the bootie. Water enters the footwear through these holes.

  An object of the present invention is to provide a footwear for fishing that is waterproof and does not detach from the upper.

The fishing footwear according to the present invention is:
upper,
Housed in this upper, made of waterproof material, bag-shaped inner material,
A sole attached to the bottom of the upper and a rivet penetrating the upper and the sole are provided.

  The upper may include a core plate that forms the bottom of the upper. The rivet can penetrate through the core plate and the sole.

  The sole may include a base and an upright portion that stands up from the base at the periphery of the base. The rivet can penetrate through the upright part and the upper part. Preferably the rivet is hollow.

The method for manufacturing fishing footwear according to the present invention comprises:
A rivet comprising a flange and a shaft is passed through the upper so that the flange contacts the inner surface of the upper;
In this upper, a process of containing a bag-shaped inner material made of a waterproof material,
The shaft is passed through the sole and the sole is joined to the upper by an adhesive, and the shaft is crimped to form an outer flange.

  In this fishing footwear, the upper and the sole are firmly joined by rivets. In this footwear, the sole does not come off. In this footwear, the waterproofness of the inner material is not hindered.

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

  FIG. 1 is a front view showing a fishing footwear 2 according to an embodiment of the present invention. FIG. 2 is an enlarged cross-sectional view taken along the line II-II in FIG. A part of the footwear 2 is shown in FIG. The footwear 2 includes an upper 4, a sole 6, a felt 8, a hook-and-loop fastener 10, an inner member 12, a rivet 14, and an insole 15.

  The upper 4 includes a main body 16, a tongue 18, a core plate 20, a spacer 22, and a string 24. The main body 16 is made of cloth. Typically, a mesh cloth is used for the main body 16. The main body 16 may be made of synthetic resin or rubber. The tongue 18 is made of the same material as that of the main body 16. The tongue 18 may include a sponge. The core plate 20 is made of a paper material. The core plate 20 forms the bottom of the upper 4. As shown in FIG. 2, the lower end of the main body 16 is bent. The edge part 26 is formed by this bending. The edge portion 26 is located on the lower side of the core plate 20. The spacer 22 is affixed to the lower surface of the core plate 20. The spacer 22 is sandwiched between the left and right edge portions 26. The spacer 22 is made of cloth.

  The sole 6 is made of rubber or synthetic resin as a base material. A typical substrate is an ethylene-vinyl acetate copolymer (EVA). The sole 6 is attached to the bottom of the upper 4. This attachment is accomplished with an adhesive. Examples of the base polymer of the adhesive include polyurethane, polychloroprene, and acrylonitrile-butadiene copolymer. Polyurethane is preferred.

  The sole 6 includes a base portion 28 and an upright portion 30. The base portion 28 and the standing portion 30 are integrally formed. The standing portion 30 stands up from the base portion 28 at the periphery of the base portion 28. As shown in FIG. 2, the upright portion 30 is joined to the outer surface of the main body 16. A recess 32 is formed on the lower surface of the base portion 28.

  The hook-and-loop fastener 10 includes a hook surface 34 and a loop surface 36. The hook surface 34 is joined to the sole 6. The loop surface 36 is joined to the felt 8. The hook surface 34 may be bonded to the felt 8 and the loop surface 36 may be bonded to the sole 6. A typical hook-and-loop fastener 10 is Velcro Velcro (registered trademark).

  The felt 8 is laminated with the sole 6 by a hook-and-loop fastener 10. The felt 8 has a ground plane 38. This ground plane 38 is in direct contact with the ground. The felt 8 suppresses slipping at a fishing spot. When the ground contact surface 38 is worn due to friction with the ground, the felt 8 is peeled off from the sole 6. Then, a new felt 8 is attached by a hook-and-loop fastener 10.

  The inner material 12 is accommodated in the upper 4. The inner material 12 is along the inner surface of the upper 4. The inner material 12 has a bag shape. The inner material 12 has a shape that covers a human foot. The inner material 12 is made of a moisture-permeable and waterproof material. The inner material 12 does not allow water molecules that are liquid to permeate. The inner member 12 can transmit water molecules that are gases. A typical moisture permeable waterproof material is Gore-Tex®.

  The rivet 14 is made of a metal material. The rivet 14 is hollow. The rivet 14 includes an inner flange 40, a shaft 42 and an outer flange 44. The inner flange 40 is along the upper surface of the core plate 20. The shaft 42 passes through the core plate 20, the spacer 22, and the sole 6. The outer flange 44 is located in the recess 32. The upper 4 and the sole 6 are firmly fixed by the rivet 14. The rivet 14 does not penetrate the inner material 12. FIG. 2 shows a pair of rivets 14 that exist along the width direction. A plurality of rivets 14 may be arranged in the front-rear direction.

  In the footwear 2, the adhesive between the upper 4 and the sole 6 may deteriorate due to exposure to seawater. The sole 6 peels from the upper 4 due to deterioration. In the footwear 2, since the sole 6 is fixed to the upper 4 by the rivets 14, the sole 6 does not separate from the upper 4 even if peeling occurs. Even if separation occurs at the fishing spot, the angler can continue fishing and can move around by walking.

  As described above, the rivet 14 does not penetrate the inner member 12. Therefore, no hole due to the rivet 14 is formed in the inner material 12. The inner material 12 prevents water from entering the footwear 2. The footwear 2 is excellent in waterproofness. The angler can use the footwear 2 comfortably.

  Since the inner material 12 is moisture permeable, water vapor generated by perspiration can pass through the inner material 12 and be exhausted to the outside of the footwear 2. Anglers do not feel stuffy. The angler can use the footwear 2 comfortably.

  3 to 6 are cross-sectional views for explaining a method of manufacturing the footwear 2 of FIG. In FIG. 3, the upper 4 and the rivet 14 are shown. The rivet 14 includes an inner flange 40 and a shaft 42. At this stage, the outer flange 44 (see FIG. 2) is not formed on the rivet 14. The shaft 42 passes through the core plate 20 and the spacer 22. The inner flange 40 is in contact with the upper surface of the core plate 20. Preferably, the inner flange 40 is joined to the core plate 20 by an adhesive.

  The inner material 12 is accommodated in the upper 4. FIG. 4 shows the inner material 12. The inner material 12 is along the inner surface of the upper 4. The inner flange 40 is covered by the inner surface. Since the inner material 12 is accommodated in the upper 4 after the rivet 14 is passed through the upper 4, no hole due to the rivet 14 is generated in the inner material 12.

  A sole 6 is attached to the upper 4 with an adhesive. FIG. 5 shows the sole 6. When pasting, the shaft 42 of the rivet 14 is passed through a hole 46 formed in the sole 6 in advance. In plan view, the position of the hole 46 coincides with the position of the recess 32. As shown in FIG. 5, the lower end of the shaft 42 reaches the recess 32.

  As shown in FIG. 6, the lower end of the shaft 42 is caulked to form an outer flange 44. The outer flange 44 is located in the recess 32. When the upper 4 and the sole 6 are sandwiched between the inner flange 40 and the outer flange 44, the sole 6 is fixed to the upper 4. For the convenience of manufacturing the footwear 2, the inner material 12 needs to be accommodated in the upper 4 before the sole 6 is attached to the upper 4. In the manufacturing method according to the present invention, since the rivet 14 penetrates the upper 4 in advance before the inner material 12 is accommodated in the upper 4, no hole is formed in the inner material 12. By this manufacturing method, it is possible to obtain the footwear 2 which is excellent in waterproofness and hardly causes the sole 6 to be detached from the upper 4.

  FIG. 7 is a cross-sectional view showing a part of a fishing footwear 48 according to another embodiment of the present invention. The footwear 48 includes an upper 50, a sole 52, a felt 8, a hook-and-loop fastener 10, an inner member 12, a rivet 14, and an insole 15. The configuration of the felt 8, the hook-and-loop fastener 10, the inner member 12, the rivet 14, and the insole 15 is equivalent to that of the footwear 2 shown in FIGS.

  The upper 50 includes a main body 54, a core plate 56, and a spacer 58. The main body 54 includes a side wall 60 and an edge 62. A hole 64 is formed in the side wall 60. Unlike the footwear 2 shown in FIG. 2, no holes are formed in the core plate 56 and the spacer 58. The sole 52 includes a base portion 66 and an upright portion 68. A hole 70 is formed in the standing portion 68.

  The rivet 14 is hollow. The rivet 14 includes an inner flange 40, a shaft 42 and an outer flange 44. The inner flange 40 is along the inner surface of the side wall 60. The shaft 42 passes through the side wall 60 and the upright portion 68. The outer flange 44 is along the outer surface of the side wall 60. The upper 50 and the sole 52 are firmly fixed by the rivet 14. The rivet 14 does not penetrate the inner material 12. FIG. 7 shows a pair of rivets 14 that exist along the width direction. A plurality of rivets 14 may be arranged in the front-rear direction.

  In manufacturing the footwear 48, the rivet 14 including the inner flange 40 and the shaft 42 is passed through the side wall 60 from the inside to the outside. The inner flange 40 is joined to the inner surface of the side wall 60 by an adhesive. Next, the inner member 12 is accommodated in the upper 50. Next, the shaft 42 is crimped to form an outer flange 44. In the manufacture of the footwear 48, the rivet 14 penetrates the upper 50 in advance before the inner material 12 is accommodated in the upper 50, so that no hole is formed in the inner material 12. According to this manufacturing method, a shoe that is excellent in waterproofness and is unlikely to cause the release of the sole 52 from the upper 50 can be obtained.

  As described above, the rivet 14 is hollow. The water vapor generated inside the footwear 48 passes through the inner material 12 and is further discharged to the outside through the rivet 14. The footwear 48 is excellent in breathability.

  The footwear according to the present invention can be used in various fishing grounds. The footwear according to the present invention includes boots and waders.
