Description

  The present invention relates to footwear worn by anglers.

  In carp fishing, the angler moves on a rock, walks for good points, and jumps. In these movements, the angler's shoes collide with and rub against the rock. The upper part of the shoe is damaged by collision and friction. A damaged upper does not protect the angler's feet sufficiently. Severely damaged shoes can no longer withstand use.

  If the upper is made of a material having excellent strength, damage is suppressed. However, materials that are superior in strength are generally less flexible. An inferior upper prevents the foot from bending. Shoes with this upper are inferior in comfort.

Japanese Patent Application Laid-Open No. 2001-204506 discloses a fishing footwear provided with a hood-like reinforcing material covering the upper. This reinforcing material is made of a hard synthetic resin. This reinforcement prevents damage to the upper.
JP 2001-204506 A

  In the shoe disclosed in the above publication, the reinforcing material hinders flexibility. This shoe is inferior in comfort. An object of the present invention is to provide fishing footwear in which damage to the upper is suppressed and the flexibility is excellent.

  The fishing footwear according to the present invention includes an upper and an outsole. This outsole is provided with a bump-like projection on its side wall surface.

  Another fishing footwear according to the present invention includes an upper and an outsole. The outsole includes a first knob-like projection, a second knob-like projection adjacent to the first knob-like projection, and the first knob-like projection and the second knob-like projection on the outside of the side wall surface. And an outside concave portion located between them. The outsole further includes a third knob-like projection, a fourth knob-like projection adjacent to the third knob-like projection, and the third knob-like projection and the fourth knob-like projection on the inside of the side wall surface. And an inside recessed portion located therebetween. The outside recessed portion and the inside recessed portion are located on the bent surface of the footwear. Preferably, the depth of the outside recessed portion and the inside recessed portion is 1 mm or more.

  In the fishing footwear according to the present invention, the bumps of the outsole collide with the rock. The bumps prevent the upper from colliding with the rock and the friction between the upper and the rock. In this footwear, damage to the upper is suppressed. The bumps do not hinder the upper flexibility. This footwear is also excellent in comfort.

  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, and FIG. 2 is a plan view thereof. FIG. 1 shows the outside of the footwear 2. The footwear 2 includes an upper 4, a heel guard 6, an outside guard 8, an inside guard 10, a string 12 and an outsole 14. In FIG. 2, the illustration of the string 12 is omitted.

  The upper 4 is made of a mesh-like fabric. The upper 4 is water permeable. The upper 4 is lightweight and flexible. The upper 4 is excellent in flexibility. The upper 4 includes eyelets 16. A string 12 is passed through the eyelet 16. The upper 4 also includes a flap 18.

  The heel guard 6 covers the vicinity of the heel of the upper 4. The heel guard 6 is made of a hard synthetic resin. As shown in FIG. 1, the heel guard 6 includes an opening 20. As shown in FIG. 2, the heel guard 6 includes a pair of left and right arms 22. The arm 22 extends to the toe side of the wearer's ankle. The arm 22 includes a through hole 24 at the tip thereof.

  The outside guard 8 covers the outside of the upper 4. The outside guard 8 includes an opening 26. The inside guard 10 covers the inside of the upper 4. Although not shown, the inside guard 10 also has an opening similar to the outside guard 8. The outside guard 8 and the inside guard 10 are made of the same hard resin as the heel guard 6.

  FIG. 3 is a bottom view showing the fishing footwear 2 of FIG. 1. FIG. 3 shows footwear 2 for the right foot. The footwear 2 for the left foot has a shape obtained by inverting the shape shown in FIG. In FIG. 3, the upper side is the outside, and the lower side is the inside. The outsole 14 of the footwear 2 includes a base 28, a large number of blocks 30, and a large number of spike pins 32. The base 28 is made of a crosslinked rubber. For the base 28, rubber having excellent wear resistance and strength is used. The block 30 is made of a hard resin. The spike pin 32 is made of a metal material.

  FIG. 4 is an enlarged cross-sectional view taken along line IV-IV in FIG. In FIG. 4, the insole 34 is shown together with the upper 4 and the outsole 14. The footwear 2 may include a midsole between the insole 34 and the outsole 14. As shown in FIG. 4, most of the spike pin 32 except the tip 36 is embedded in the block 30. The spike pin 32 is firmly fixed to the block 30 by this embedding. The tip portion 36 of the spike pin 32 protrudes downward from the block 30. By slipping the front end portion 36 into the ground, the footwear 2 is prevented from slipping. A part of the block 30 is embedded in the base 28. By this embedding, the block 30 is firmly fixed to the base 28.

  As is clear from FIG. 1, the outsole 14 includes a side wall surface 38. As is apparent from FIGS. 1, 2, and 3, the side wall surface 38 includes a first knob-like protrusion 40, a second knob-like protrusion 42, a third knob-like protrusion 44, and a fourth knob-like protrusion 46. . These knob-like protrusions 40, 42, 44, 46 protrude outward. The first knob-like projection 40 and the second knob-like projection 42 are located on the outside of the footwear 2. The second knob-like protrusion 42 is adjacent to the first knob-like protrusion 40. An outside recessed portion 48 is located between the first and second protrusions 40 and 42. The third knob-like protrusion 44 and the fourth knob-like protrusion 46 are located inside the footwear 2. The fourth knob-like protrusion 46 is adjacent to the third knob-like protrusion 44. An inside recessed portion 50 is located between the third knob-like protrusion 44 and the fourth knob-like protrusion 46.

  In the production of the footwear 2, the block 30 is disposed in a mold, and the mold is filled with an uncrosslinked rubber composition. The rubber composition causes a crosslinking reaction by heating, and the outsole 14 is molded. Simultaneously with the molding, the bumps 40, 42, 44, 46 are formed. On the other hand, the heel guard 6, the outside guard 8 and the inside guard 10 are joined to the upper 4. Joining is accomplished by stitching. The joining may be performed by an adhesive. Next, the outsole 14 is joined to the upper 4. Bonding is accomplished with an adhesive. Next, the insole 34 is laminated on the outsole 14, and the insole 34 is joined to the outsole 14 with an adhesive, whereby the footwear 2 is completed.

  When the footwear 2 is worn, the wearer first puts his / her foot into the footwear 2. Next, the string 12 passed through the eyelet 16 and the through hole 24 of the arm 22 is tightened and tied. Since the arm 22 reaches the toe side of the ankle as described above, the arm 22 strongly presses the upper 4 against the ankle of the wearer when the string 12 is tightened. At this time, the tension acting on the arm 22 reaches the entire heel guard 6. Due to this tension, the upper 4 immediately below the heel guard 6 strongly presses the wearer's heel. The footwear 2 fits the foot by pressing the ankle and the heel. Although the wearer may perform a violent movement at the fishing spot, the footwear 2 fitted to the foot does not hinder this movement. Since the heel guard 6, the outside guard 8, and the inside guard 10 are hard, they contribute to the stability of the footwear 2. Further, the heel guard 6, the outside guard 8, and the inside guard 10 contribute to the protection of the upper 4.

  When the wearer performs an operation such as walking with a heel, the footwear 2 collides with a rock. As described above, since the bumps 40, 42, 44, 46 protrude outward, the bumps 40, 42, 44, 46 first collide with the rock. Therefore, the upper 4 does not collide violently with the rock, and the upper 4 does not rub against the rock violently. In the footwear 2, damage to the upper 4 is suppressed. In other words, the bumps 40, 42, 44, 46 serve to protect the upper 4. Since the protrusions 40, 42, 44, 46 are formed on the outsole 14, the flexibility of the upper 4 is not impaired. In the footwear 2, excellent flexibility is maintained.

  Since the strength of the bumps 40, 42, 44, 46 is high, even if the bumps 40, 42, 44, 46 collide with rocks, the damage of the bumps 40, 42, 44, 46 is slight. The hardness Hs of the outsole 14 measured with a JIS-A hardness meter is preferably 20 or more and 80 or less from the viewpoint of suppressing damage to the bumps 40, 42, 44, and 46.

  In FIG. 3, what is indicated by a two-dot chain line F is a bent surface. When the wearer walks while wearing the footwear 2, the outsole 14 is most deformed on the bending surface F. As apparent from FIG. 3, the outside recessed portion 48 and the inside recessed portion 50 are located on the bending surface F. The first knob-like protrusion 40 and the second knob-like protrusion 42 are opposed to each other with the bending surface F interposed therebetween. The third knob-like protrusion 44 and the fourth knob-like protrusion 46 also face each other with the bending surface F in between. In other words, the bumps 40, 42, 44, 46 are not located on the bending surface F. In the footwear 2, the bumps 40, 42, 44, 46 do not hinder the deformation of the outsole 14. The footwear 2 is extremely excellent in flexibility.
