Description

  The present invention relates to a structure of a shoe sole material used for a fishing shoe, particularly a shoe sole of a fishing shoe.

  For example, in river fishing and carp fishing, anglers walk on stones and rocks. The surface of rocks and rocks in such fishing grounds is generally wet and moss and glue are often attached. Therefore, various improvements have been added to the soles of fishing shoes worn by anglers so as not to slip during walking (see, for example, Patent Documents 1 to 6).

  Specifically, in conventional fishing shoes, (a) the sole material is made of felt, (a) the shoe sole is provided with spike pins, (c) the suction sole on the shoe sole. There are some that are provided. Fishing shoes with these improvements exhibit a certain anti-skid effect under certain conditions (fishing environment). That is, for example, when the heel is made of flat rock and is not very wet, it is preferable that the shoe sole material is made of felt, and when soft moss grows on stones and rocks and is always wet It is preferable that the shoe sole is provided with a spike pin.

  There are various fishing ground environments. In some cases, the surface of the stones scattered around the fishing ground is a smooth surface, and the surface of the rock is a wet rough surface. In some cases, soft moss grows on the rock surface, or relatively hard grass grows. Therefore, for example, a fishing shoe with a spike pin on the sole of the shoe exhibits an excellent anti-skid effect on rough rocks, but does not necessarily exhibit a high anti-skid effect in places where moss is growing. I couldn't. In other words, simply improving the structure of the sole material and the material constituting the sole material for the purpose of simply increasing the coefficient of friction between stones and rocks will provide an excellent anti-slip effect for various environments. It was difficult to demonstrate.

  The present invention has been made based on such a background, and provides a fishing shoe that exhibits an excellent anti-skid effect in any environment in a fishing spot and a shoe sole material used therefor. It is the purpose.

  (1) Human feet (especially soles) are known to exhibit excellent tactile functions. Therefore, if a fisherman can feel the condition of the stones and rocks (shape and surface condition) scattered on the fishing ground by the soles of his / her feet even when he / she is wearing fishing shoes, It is possible to grasp to some extent whether the surface of stones or rocks to be grounded is slippery. And if the angler can recognize that the surface of the stone or the rock is slippery, the angler can devise a method of grounding his / her foot to make the foot difficult to slip. The inventor of the present application pays attention to this point, and if the shoe sole has a predetermined flexibility, the angler wearing the shoe confirms the fishing ground environment (slipperiness, etc.) on the sole of his / her foot. As a result, it was considered that the fishing shoes can exhibit a high antiskid effect.

(2) Therefore, a fishing shoe according to the present invention has a shoe body into which a fisherman's foot can be inserted, and a shoe sole material provided on the outer bottom surface of the shoe body and having a constant thickness. Is provided with an arch part, a toe part that is disposed on the front side of the arch part and hinged to the arch part, and a collar part that is disposed on the rear side of the arch part and hinged to the arch part, The rigidity of the arch portion is set lower than the rigidity of the heel portion and the rigidity of the toe portion.

  According to this configuration, the shoe sole material is divided into the toe portion, the arch portion, and the heel portion, and the toe portion and the heel portion can be independently rotated and displaced with respect to the arch portion. For this reason, this shoe sole material is very easy to bend in the vertical direction. Here, the “longitudinal direction” is the length direction of the foot (the direction connecting the toe and the heel) in a state in which the angler's foot is inserted into the fishing shoe. Accordingly, the angler can easily bend the foot in the length direction even when the fishing shoe is worn. Then, the angler can bring the arch portion into contact with the stone or the rock with the foot curved in this manner. Since the rigidity of the arch portion is set low, the angler can easily recognize the state of the surface of the rocks and rocks of the fishing ground through the arch portion.

  Preferably, the shoe sole material includes a flexible sheet-like attachment member, and the arch portion, the toe portion, and the heel portion are disposed on the attachment member. In this configuration, when the mounting member is curved or bent, the toe portion and the heel portion are rotationally displaced independently of the arch portion. That is, this attachment member constitutes a hinge that connects the arch portion and the toe portion and a hinge that connects the arch portion and the heel portion. Therefore, the structure of the shoe sole material is greatly simplified.

  It is preferable that a groove having a V-shaped cross-section is provided at the boundary between the arch portion and the toe portion and at the boundary between the arch portion and the heel portion. Thereby, the groove | channel opened to the lower surface (contact surface with a stone or rock) of a shoe sole material is formed also in a normal state (state where the angler stands upright without walking). Therefore, the angler can easily bend the foot inward along the length direction while wearing the fishing shoes. That is, the angler can bend the sole material so as to hold the stone or rock by the sole of the foot. Thereby, it becomes easy for the angler to recognize the state of the surface of the rock and the rock of the fishing ground more accurately.

  It is preferable that the shoe sole material is detachably provided on the outer bottom surface of the shoe body. Thereby, when the shoe sole material is worn out, the angler can exchange only the shoe sole material.

(3) In order to achieve the above object, the shoe sole material according to the present invention is a shoe sole material provided on the outer bottom surface of a shoe body of a fishing shoe and having a constant wall thickness. A toe part hinged to the arch part and hinged to the arch part, and a collar part hinged to the arch part and hinged to the arch part, and the rigidity of the arch part is It is characterized by being set lower than the rigidity of the part and the rigidity of the toe part.

  According to this configuration, the shoe sole material is attached to the outer bottom surface of the shoe body of the fishing shoe, and the angler wears the fishing shoe in this state. The shoe sole material is divided into three parts, a toe part, an arch part, and a heel part, and the toe part and the heel part can be independently rotated and displaced with respect to the arch part. For this reason, this shoe sole material is very easy to bend in the vertical direction. Here, the “longitudinal direction” is the length direction of the foot (the direction connecting the toe and the heel) in a state where the fisherman's foot is inserted into the fishing shoe. Therefore, the angler can easily bend the foot in the length direction even when the fishing shoe is worn. Then, the angler can bring the arch portion into contact with the stone or the rock with the foot curved in this manner. Since the rigidity of the arch portion is set low, the angler can easily recognize the state of the surface of the rocks and rocks of the fishing ground through the arch portion.

  It is preferable that the arch portion, the toe portion, and the heel portion are disposed on a flexible sheet-like attachment member. In this configuration, the toe portion and the heel portion are rotationally displaced independently of the arch portion by the deformation of the mounting member. That is, this attachment member constitutes a hinge that connects the arch portion and the toe portion and a hinge that connects the arch portion and the heel portion. Therefore, the structure of the shoe sole material is greatly simplified.

  It is preferable that a groove having a V-shaped cross-section is provided at the boundary between the arch portion and the toe portion and at the boundary between the arch portion and the heel portion. Thereby, the groove | channel opened to the lower surface (contact surface with a stone or rock) of a shoe sole material is formed also in a normal state (state where the angler stands upright without walking). Therefore, the angler can easily bend the foot inward along the length direction while wearing the fishing shoes. That is, the angler can bend the sole material so as to hold the stone or rock by the sole of the foot. Thereby, it becomes easy for the angler to recognize the state of the surface of the rock and the rock of the fishing ground more accurately.

  It is preferable that the shoe sole material is detachably provided on the outer bottom surface of the shoe main body. Thereby, when a shoe sole material is worn out, the angler can exchange only the shoe sole material.

  According to the present invention, since the shoe sole material is easily deformed, the angler can recognize the state of the surface of the stone or the rock that is intended to ground the foot with the sole of his / her foot. As a result, the angler can devise how to ground his / her foot, and as a result, the fishing shoe exhibits an excellent anti-skid effect even in any environment at the fishing spot.

  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 of a fishing shoe according to an embodiment of the present invention, and FIG. 2 is an enlarged cross-sectional view of a main part of the fishing shoe.

  The fishing shoe 10 is worn by a fisherman for walking safely at a fishing spot in river fishing, for example. A feature of the fishing shoe 10 according to the present embodiment is a structure of a sole portion of the fishing shoe 10. That is, when the fishing shoe 10 includes the sole material 13 described later, a high anti-skid effect is exhibited when the angler walks in the fishing ground. In addition, although a fisherman wears a pair of fishing shoes 10 formed symmetrically, in order to simplify the description, the structure of the fishing shoes 10 for the right leg will be described below.

  The fishing shoe 10 includes a shoe main body 11 and a shoe sole material 13 provided on the outer bottom surface 31 of the shoe main body 11. The shoe main body 11 includes a midsole portion 12 at a lower portion, and a shoe sole material 13 is attached to the midsole portion 12.

  The shoe body 11 includes an inner cloth 14, a body rubber 15, reinforcing rubbers 16 to 20, and an insole 21.

  The inner cloth 14 is made of nylon or other polyester, for example, and constitutes the inner wall surface of the shoe body 11. When the inner cloth 14 is made of nylon or other polyester, the angler can comfortably wear the fishing shoes 10. The insole 21 is disposed on the inner bottom 23 of the inner cloth 14. The inner bottom portion 23 of the inner cloth 14 constitutes a placement portion on which the sole portion of the foot is placed when the angler wears the fishing shoes 10. The insole 21 is made of, for example, foamed ethylene vinyl acetate copolymer (foamed EVA), foamed polyurethane (foamed PU), foamed polyethylene (foamed PE), sponge, or the like. For this reason, when the angler wears the fishing shoe 10, the fishing shoe 10 fits the foot, and the angler becomes more comfortable to wear. However, the insole 21 may be omitted.

  The main rubber 15 is disposed so as to surround the outer peripheral surface excluding the bottom of the inner cloth 14. The main rubber 15 forms the skeleton of the shoe main body 11. As the main rubber 15, for example, natural rubber (NR), polyvinyl chloride (PVC), or other synthetic rubber is employed. The reinforcing rubber 16 is disposed so as to cover the tip portion (toe side) of the shoe main body 11, and reinforces the portion. As the reinforcing rubber 16, for example, natural rubber (NR), polyvinyl chloride (PVC), or other synthetic rubber is used. Further, the reinforcing rubber 17 is disposed so as to cover the rear end portion (heel side) of the shoe main body 11 and reinforces the portion. The reinforcing rubber 17 has a thick portion 22 in particular. The thick portion 22 is provided in a portion corresponding to the rear side of the angler's heel when the angler wears the fishing shoes 10, and the safety of the angler's heel portion is ensured. As the reinforcing rubber 17, for example, natural rubber (NR), polyvinyl chloride (PVC), or other synthetic rubber is used.

  The reinforcing rubber 18 is disposed in the vicinity of the bottom portion of the shoe main body 11 and is disposed along the circumferential direction of the shoe main body 11. That is, the reinforcing rubber 18 is disposed so as to surround the lower edge portion of the shoe main body 11 and further reinforces the front end portion and the rear end portion of the shoe main body 11. As the reinforcing rubber 18, for example, natural rubber (NR), polyvinyl chloride (PVC), or other synthetic rubber is employed. Further, the reinforcing rubber 19 is disposed outside the reinforcing rubber 18. The reinforcing rubber 19 is provided in the vicinity of the bottom of the shoe body 11 and is disposed along the circumferential direction of the shoe body 11. Thereby, the reinforcement rubber 19 has further reinforced the front-end | tip part and lower end part of the shoe main body 11, and the durability and safety | security of the fishing shoe 10 are improved. As the reinforcing rubber 19, for example, natural rubber (NR), polyvinyl chloride (PVC), or other synthetic rubber is used. Further, the reinforcing rubber 20 is disposed at the peripheral edge of the upper opening 36 (the part into which the fisherman's leg is inserted) of the shoe body 11. The reinforcing rubber 20 reinforces the peripheral edge. As the reinforcing rubber 20, for example, natural rubber (NR), polyvinyl chloride (PVC), or other synthetic rubber is employed.

  The midsole portion 12 is disposed on the bottom surface 24 outside the inner cloth 14. However, a reinforcing sheet 25 is disposed on the bottom peripheral edge of the shoe body 11. Therefore, the midsole portion 12 is fixed to the bottom surface 24 with the reinforcing sheet 25 interposed therebetween. The midsole portion 12 includes a base portion 26, a seat member 27, and a cushion member 28. The base portion 26 is made of, for example, synthetic rubber, and the outer shape thereof corresponds to the shape of the bottom surface 24. The seat member 27 is disposed on the upper surface of the base portion 26, and a cushion member 28 is disposed on the upper surface of the seat member 27. In other words, the base 26, the seat member 27, and the cushion member 28 are laminated in order, and these are integrally attached to the bottom surface 24 on the outer side of the inner cloth 14. The bottom surface of the base portion 26 constitutes the outer bottom surface 31 of the shoe body 11. The outer bottom surface 31 includes a recess 32 for mounting a shoe sole material 13 to be described in detail later.

  The sheet member 27 is made of a thin plate material. As the material constituting the sheet member 27, for example, rubber, felt, plastic, metal, or the like can be adopted in addition to a paper material impregnated with resin. The cushion member 28 is made of a foam molded member such as a foamed ethylene vinyl acetate copolymer, a foamed synthetic rubber, a foamed natural rubber, a foamed urethane, or a felt material. In the present embodiment, the cushion member 28 is laminated on the upper surface of the seat member 27, but the cushion member 28 may be disposed on the upper surface of the base portion 26, and the seat member 27 may be disposed on the upper surface thereof. However, the seat member 27 and the cushion member 28 may be omitted.

  FIG. 3 is a perspective view of the shoe sole material 13. In the figure, the upper surface of the shoe sole material 13 is the lower surface 40 of the shoe sole material 13 (see FIG. 2).

  As shown in FIGS. 2 and 3, the shoe sole material 13 is detachably attached to the outer bottom surface 31 of the shoe main body 11. The shoe sole material 13 includes an attachment member 33. The shoe sole material 13 is formed in a plate shape, and its outer shape is formed so as to correspond to the outer bottom surface 31 of the shoe main body 11. Specifically, the outer shape of the shoe sole material 13 is formed so as to fit exactly into the recess 32 provided in the outer bottom surface 31. The thickness D of the shoe sole material 13 is set to 15 mm in this embodiment. However, the thickness D can be set as appropriate within a range of 10.0 mm to 20.0 mm.

  The shoe sole material 13 is divided into three parts in this embodiment. That is, the shoe sole material 13 includes an arch portion 81, a toe portion 82, and a heel portion 83 disposed in the center portion. The arch portion 81 corresponds to the arch portion of the sole of the foot when the angler is wearing the fishing shoes 10. The toe portion 82 is disposed on the front side of the arch portion 81 and corresponds to a portion from the toe to the arch on the sole of the angler's foot. The heel portion 83 is disposed on the rear side of the arch portion 81 and corresponds to the heel portion on the sole of the angler's foot. The arch portion 81, the toe portion 82, and the flange portion 83 are adjacent to each other, and are disposed on the attachment member 33 and fixed to the attachment member 33. The arch portion 81 and the toe portion 82, and the arch portion 81 and the collar portion 83 are hinged as described later. Therefore, the toe portion 82 is rotatable with respect to the arch portion 81, and the collar portion 83 is rotatable with respect to the arch portion 81.

  The arch portion 81, the toe portion 82, and the heel portion 83 are each formed in a block shape as shown in FIG. The arch portion 81, the toe portion 82, and the heel portion 83 are mainly composed of felt. In other words, the arch portion 81, the toe portion 82, and the heel portion 83 are configured by gathering fibers in three dimensions and without regularity of direction. As the fiber type, for example, natural fibers such as coconut fiber and hemp can be adopted in addition to synthetic fibers such as nylon and polyester. However, the rigidity of the arch portion 81 (rigidity as a structure) is set lower than the rigidity of the toe portion 82 and the rigidity of the collar portion 83. As means for suppressing the rigidity of the arch portion 81, for example, means for reducing the density of the fibers, means for using fibers with low rigidity, and the like are conceivable.

  FIG. 4 is a cross-sectional view taken along the line IV-IV of the shoe sole material 13 and shows a state in which the shoe sole material 13 is bent.

  As shown in FIGS. 3 and 4, the attachment member 33 is attached to the upper surface 39 of the shoe sole material 13. The attachment member 33 is a thin flat plate (sheet) member and covers the upper surface 39 (the lower surface in FIG. 3) of the shoe sole material 13. The attachment member 33 is made of a nonwoven fabric containing synthetic fibers such as nylon and other polyesters, and has excellent flexibility. The arch portion 81, the toe portion 82, and the collar portion 83 are adjacent to each other but are not fixed to each other. Therefore, when the attachment member 33 is bent, the shoe sole material 13 can be bent from the posture shown in FIG. 3 to the posture shown in FIG. That is, as described above, the arch portion 81 and the toe portion 82 are hinge-coupled, and the arch portion 81 and the collar portion 83 are hinge-coupled. And the said sheet-like attachment member 33 comprises the hinge which connects the arch part 81 and the toe part 82, and comprises the hinge which connects the arch part 81 and the collar part 83. FIG.

  In this embodiment, since the attachment member 33 constitutes a hinge, there is an advantage that the structure of the shoe sole material 13 provided with the hinge mechanism is greatly simplified. However, as a matter of course, a hinge member for connecting the arch portion 81 and the toe portion 82 and the arch portion 81 and the collar portion 83 may be provided separately.

  In the present embodiment, a hook-and-loop fastener mechanism is configured between the attachment member 33 and the wall surface of the recess 32. That is, the fiber is formed in a loop shape on the surface of the mounting member 33 (the lower surface in FIGS. 3 and 4), and the fiber is formed in a hook shape on the inner surface of the recess 32. Therefore, when the shoe sole material 13 is fitted into the recess 32, the attachment member 33 is detachably engaged with the wall surface of the recess 32 with a certain holding force. As a result, the shoe sole material 13 is detachably held on the midsole portion 12 with a constant holding force. But the attachment member 33 may be comprised from the loop tape, and the hook tape engaged with this loop tape may be provided in the said recessed part 32. FIG.

  This fishing shoe 10 is generally manufactured as follows. A foot shape is used for manufacturing the fishing shoes 10. First, the inner cloth 14 is put on the foot mold. The main body rubber 15 is covered so as to cover the inner cloth 14. Next, the cushion member 28 and the sheet member 27 are affixed to the bottom part of the inner fabric 14, and the said reinforcement sheet 25 and each reinforcement rubber 16-20 are affixed in order. And the base 26 of the midsole part 12 is affixed so that the bottom part of the shoe main body 11 may be covered. The main body rubber 15, the reinforcing rubbers 16, and the like and the base 26 are fixed by a known adhesive, vulcanization treatment, or the like. The insole 21 is inserted from the upper opening 36 of the shoe main body 11 and is disposed on the inner bottom portion of the shoe main body 11. The shoe sole material 13 is assembled in advance as a separate part. The shoe sole material 13 is fixed to the midsole portion 12 via the hook-and-loop fastener mechanism only by being fitted into the recess 32 of the midsole portion 12. In the present embodiment, the shoe sole material 13 is detachably attached to the shoe main body 11, but the shoe sole material 13 may be fixed to the shoe main body 11.

  The angler can put on the fishing shoe 10 by inserting his / her foot through the upper opening 36 (see FIG. 1). When the angler wears the fishing shoes 10 and walks the fishing ground, the shoe sole material 13 is divided into the toe portion 82, the arch portion 81 and the heel portion 83, so that the toe portion 82 with respect to the arch portion 81. And the collar part 83 can each be rotationally displaced independently (refer FIG. 4). That is, the shoe sole material 13 is very easily bent in the vertical direction. The “longitudinal direction” is the length direction of the angler's foot (the direction connecting the tiptoe and the heel). Therefore, the angler can easily bend (warp) the foot in the length direction even when the fishing shoe 10 is worn. And the angler can make the arch part 81 contact | abut on a stone or a rock in the state which bent the leg in this way. Moreover, since the rigidity of the arch portion 81 is set low as described above, the angler can recognize the state of the surface of the rocks and rocks of the fishing ground through the arch portion 81.

  Since the shoe sole material 13 is easily deformed in this way, the angler can recognize the state of the surface of the stone or rock that is intended to ground the foot with the sole of his / her foot. Therefore, the angler can devise how to ground his / her foot, and as a result, the fishing shoe 10 exhibits an excellent anti-skid effect even in any environment at the fishing spot.

  Next, a modified example of this embodiment will be described. FIG. 5 is a cross-sectional view of a shoe sole material 73 according to a modification of the present embodiment.

  The sole material 73 according to this modification differs from the sole material 13 according to the above embodiment in that the boundary between the arch portion 81 and the toe portion 82 and the boundary between the arch portion 81 and the heel portion 83 are respectively V-shaped grooves 84 and 85 are provided. In addition, about another structure, it is the same as that of the said embodiment.

  By providing such grooves 84 and 85, an opening that is exposed on the lower surface 40 (contact surface with stone or rock) of the shoe sole material 73 is formed at all times. In this case, “always” means that the angler is standing upright (normal state) without walking while wearing the fishing shoes 10. Since the opening is formed in the lower surface 40 of the sole material 73 at all times, the angler can very easily bend the foot inward and outward along the vertical direction while wearing the fishing shoe 10. Can do. That is, the angler can bend the sole material 73 so as to hold a stone or a rock by the sole of his / her foot. Therefore, the angler can more accurately recognize the state of the surface of the rocks and rocks of the fishing ground, and as a result, the fishing shoe 10 has an advantage of exhibiting an even higher antiskid effect.

  The present invention can be applied to fishing shoes used for river fishing and carp fishing.
