Description

[Technical Field]

[0001] The present invention relates to fishing shoes. [Background technology]

[0002] For example, Patent Document 1 discloses fishing shoes with a sole fixed to the bottom surface of the shoe body, the sole having multiple pin-shaped protrusions and multiple plate-shaped protrusions arranged between each pin-shaped protrusion and the periphery of the sole. With this configuration, the fishing shoes of Patent Document 1 are less likely to slip even on uneven fishing grounds such as rocky areas. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2011-177069 Summary of the Invention [Problem to be solved by the invention]

[0004] When walking in fishing shoes, the heel, sole (arch), and toes touch the ground in that order, and then leave the ground. The above-mentioned conventional fishing shoes have thick soles and hard plate-like protrusions on the periphery of the soles, making the soles difficult to flex. Therefore, conventional fishing shoes have room for improvement in terms of ease of walking.

[0005] In view of this background, an object of the present invention is to provide fishing shoes that are non-slip and easy to walk in. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems, the fishing boots of the present invention have a ground contact surface of the sole having a toe side region and a heel side region, a series of base groups in the toe side region consisting of multiple bases protruding from the ground contact surface and arranged in the width direction, and a space portion between the front base group and the rear base group where no bases are arranged continuously from one end to the other in the width direction of the sole, and the base groups and the space portion are arranged in a curved shape so that they are convex toward the toe side when viewed in a plane.

[0007] According to the present invention, the fishing shoes have a base that makes them less slippery, and the fishing shoes have a space that makes them more flexible and easier to walk in.

[0008] It is preferable that at least two or more space portions are arranged in the toe side region, and that the base groups and the space portions are provided alternately in the front-to-rear direction of the sole.

[0009] According to the present invention, the fishing shoes are made even easier to walk in by providing multiple spaces.

[0010] The space portion is preferably arranged along the joint of the foot bones.

[0011] According to the present invention, the fishing boots are more flexible in accordance with the bending of the joints of the bones of the foot, making walking even easier.

[0012] The base preferably has a substantially triangular or hexagonal shape in plan view.

[0013] According to the present invention, the fishing boots make it easy to arrange the base and auxiliary protrusions on the sole and also make it easy to secure a space.

[0014] Between adjacent bases, it is preferable to have either or both of an auxiliary protrusion that protrudes from the contact surface and is taller than the base, and an auxiliary protrusion that protrudes from the contact surface and is shorter than the base.

[0015] According to the present invention, fishing boots have auxiliary protrusions that are different in height from the base, making them less likely to slip even when they come into contact with uneven ground, such as rocky areas. Also, by properly positioning the base and auxiliary protrusions so that uneven areas on the ground are properly aligned, pressure on the base is reduced, making it less likely to be damaged and improving the durability of the base.

[0016] The fishing boot is preferably embedded inside the base and has a protruding pin that protrudes from the end face of the base.

[0017] According to the present invention, the fishing boots are provided with protruding pins, which makes them more slip-resistant. Also, the base is less likely to be damaged, improving the durability of the base. [Effects of the Invention]

[0018] According to the present invention, fishing shoes that are non-slip and easy to walk in can be provided. [Brief explanation of the drawings]

[0020] The embodiments will be described below with reference to the drawings. However, the following embodiments are merely examples of fishing shoes that embody the technical concept of the present embodiment, and are not intended to be limiting. Furthermore, unless otherwise specified, the dimensions, materials, shapes, and relative positions of the components described in the embodiments are merely examples and are not intended to limit the scope of the present invention. The sizes and positional relationships of the components shown in each drawing may be exaggerated or simplified for clarity. Furthermore, some elements may be omitted to avoid overly complex drawings.

[0021] In this embodiment, in FIG. 1, the front side is the toe side, the rear side is the heel side, the left side is the medial side, and the right side is the lateral side.

[0022] 1 and 2, the fishing shoes 100 of this embodiment are configured to include a shoe body 1 that covers a person's foot, and a sole 10 that is adhered and fixed to the shoe body 1. The sole 10 has an outsole 2 and a midsole 3.

[0023] The shoe body 1 is made of a material such as cloth, leather, or rubber, and a sole 10 having a predetermined thickness is fixed to almost the entire back surface (bottom surface) of the shoe body 1 by adhesive or the like. Examples of materials for the sole 10 include rubber, urethane, and synthetic resins such as EVA.

[0024] 1, fishing shoes 100 according to this embodiment have a ground contact surface 11 of a sole 10 having a toe region TR and a heel region HR, a series of base groups 20G consisting of a plurality of bases 20 provided in the toe region TR protruding from the ground contact surface 11 in the width direction, and a space portion 30 between the front base group 20G and the rear base group 20G where no bases 20 are arranged continuously from end to end in the width direction of the sole 10. The base group 20G and the space portion 30 are arranged in a curved shape so as to be convex toward the toe side when viewed in a plane.

[0025] In this embodiment, the toe side region TR is the area in front of line AA in Fig. 1, and the heel side region HR is the area behind line AA in Fig. 1. Line AA in Fig. 1 can be, for example, a line connecting the deepest part of the curve that is convex toward the fishing shoe 100 on the medial side of the sole 10 and the deepest part (the narrowest part) of the curve that is convex toward the fishing shoe 100 on the lateral side of the sole 10.

[0026] The base group 20G is composed of a plurality of bases 20 formed integrally with the sole 10 in the toe side region TR. The material of the bases 20 is the same as that of the sole 10. The bases 20 protrude from the ground contact surface 11 in the toe side region TR. The ground contact surface 11 of the sole 10 is the surface that comes into contact with the ground or faces the ground when the fishing shoe 100 is in use. A plurality of bases 20 constituting the base group 20G are provided in the toe side region TR in the width direction of the sole 10. In this embodiment, three or four bases 20 are arranged in the width direction of the sole 10 as the bases 20 constituting the base group 20G. The provision of the bases 20 makes the fishing shoe 100 less slippery and easier to walk on.

[0027] The base 20 is formed in a truncated cone shape so that the side surface slopes inward in a cross-sectional view in the direction protruding from the sole 10. In other words, the base 20 is formed in a columnar shape tapering toward the tip in the direction protruding from the sole 10. In addition, the side surface of the base 20 is curved so as to be recessed inward in a plan view.

[0028] The base 20a (see FIG. 1), located on the inner side of the fishing shoe 100, extends to the inner side of the fishing shoe 100. The base 20c, located on the outer side of the fishing shoe 100, extends to the outer side of the fishing shoe 100. In the width direction of the fishing shoe 100, the base 20b, located between the bases 20a and 20c, has a substantially triangular or hexagonal shape in plan view. The term "substantially triangular" is not limited to a triangular shape and includes, for example, shapes with rounded corners and shapes with curved sides. The term "substantially hexagonal" is not limited to a hexagonal shape and includes, for example, shapes with rounded corners and shapes with curved sides. The bases 20a and 20b can also be considered to be substantially triangular or hexagonal in plan view. In this embodiment, the base 20 is both substantially triangular and substantially hexagonal. In the fishing shoes 100, the base 20 is made to have a substantially triangular or hexagonal shape in plan view, which makes it easier to arrange the base 20 and auxiliary protrusions 50 and 60 (described later) on the sole 10 and also makes it easier to secure the space portion 30. The shape of the base 20 in plan view may vary depending on the location where it is arranged.

[0029] FIG. 3 is an enlarged view of the portion indicated by the symbol B in FIG. 2. As shown in FIG. 3, the fishing shoe 100 is provided with a protruding pin 40 that is embedded inside the base 20 and protrudes from the end surface 20x of the base 20. The protruding pin 40 has a flat plate portion 41, a first protruding portion 42, and a second protruding portion 43. The flat plate portion 41 is, for example, circular in plan view, e.g., disk-shaped. The flat plate portion 41 is disposed inside the sole 10. The first protruding portion 42 is formed integrally with the flat plate portion 41, rises from the flat plate portion 41, and protrudes from the end surface 20x of the base 20. A portion of the first protruding portion 42 is disposed inside the base 20, and a portion protrudes from the end surface 20x of the base 20. The second protruding portion 43 is, for example, fitted into a recess formed in the end surface 42x of the first protruding portion 42, and protrudes from the end surface 42x of the first protruding portion 42. The fishing shoes 100 are made even less slippery by being provided with the protruding pins 40. In addition, the base 20 is less likely to be damaged, and the durability of the base 20 is improved.

[0030] The flat plate portion 41 and the first protrusion 42 are made of, for example, stainless steel. By making the flat plate portion 41 and the first protrusion 42 out of stainless steel, the strength of the flat plate portion 41 and the first protrusion 42 is improved. The second protrusion 43 is made of, for example, tungsten. By making the second protrusion 43 out of tungsten, the strength of the second protrusion 43 is further improved. The height H1 of the base 20 is, for example, 5.2 to 6.2 mm. The height H2 of the first protrusion 42 protruding from the end face 20x of the base 20 is, for example, 1.5 to 2.1 mm. The height H3 of the second protrusion 43 protruding from the end face 42x of the first protrusion 42 is, for example, 0.9 to 1.5 mm. The protrusion pin 40 can be formed, for example, by insert molding when the sole 10 is manufactured.

[0031] As shown in FIG. 1, the sole (sole portion) 10 is provided with a plurality of base groups 20G. In this embodiment, five base groups 20G (five rows) are arranged in the toe side region TR of the fishing shoe 100. The most distal base 20 on the toe side is formed by two adjacent bases being integrated together, and each base 20 has two protruding pins 40. In this embodiment, this most distal base 20 is not included in the base group 20G. However, if a predetermined space portion 30 can be secured, this most distal base 20 may be considered as two bases and included in the base group 20G.

[0032] The space portion 30 is an area between the front base group 20G and the rear base group 20G where no bases 20 are arranged continuously from end to end in the width direction of the sole 10. In this embodiment, the space portion 30 is an area between the front base group 20G and the rear base group 20G where no auxiliary protrusions 50, 60 are arranged continuously from end to end in the width direction of the sole 10. The space portion 30 is, for example, an area that can draw an arc of a predetermined thickness from end to end in the width direction of the sole 10 in a plan view. In other words, for example, the area between bases 20 adjacent to each other in the width direction of the sole 10 is not included in the space portion 30.

[0033] The base group 20G and the space portion 30 are arranged in a curved shape that is convex toward the toe when viewed in a plane. The curved shape of the base group 20G and the space portion 30 may be an arc or another quadratic curve. In FIG. 1, for convenience, the curvature of the space portion 30 is indicated by line L1. Note that the curved shape of the base group 20G refers to, for example, a line passing through the center of the base 20 or a position near it, such as a line passing through the position of the protruding pin 40. In FIG. 1, for convenience, the curvature of the base group 20G is indicated by line L2. The curvatures of the base group 20G and the space portion 30 each have, for example, a constant curvature. In a plane view, the base 20 is slightly curved and rounded so that the vertices are convex outward. In addition, in a plane view, the base 20 is slightly curved and rounded so that the sides are convex inward. One vertex of the base 20 faces the toe side, and one side faces the heel side. This makes it easier for the space portion 30 to be arranged in a curved shape that is convex toward the toe side without being interfered with by the base 20. The fishing shoes 100 have the space portion 30, which makes it easier for the fishing shoes 100 to bend in the space portion 30. This makes it easier to walk.

[0034] It is preferable that at least two or more space portions 30 are arranged in the toe side region TR, and the base groups 20G and the space portions 30 are arranged alternately in the front-to-back direction of the sole 10. In this embodiment, the fishing shoes 100 have five base groups 20G and four space portions 30 arranged alternately in the front-to-back direction of the sole 10 in the toe side region TR of the fishing shoes 100. The four space portions 30 are arranged at approximately equal intervals in the front-to-back direction of the fishing shoes 100. By arranging multiple space portions 30 in the fishing shoes 100, the fishing shoes 100 can be easily flexed at the multiple space portions 30, making it easier to walk. The four space portions 30 each have a different degree of curvature. In this embodiment, the curvature (degree of curvature) increases as you move toward the rear of the fishing shoes 100. The first and second space portions 30 from the front have their curvatures adjusted so as to better fit the joints of the foot bones 200, as will be described later.

[0035] The space portions 30 are preferably arranged along the joints of the foot bones 200. As shown in FIG. 5, the bones 200 of a human foot include an IP joint 201, a DIP joint 202, a PIP joint 203, a MP joint 204, and a Lisfranc joint 205. In FIG. 5, for convenience, the rough curves connecting these joints are indicated by a line L3. In the fishing shoe 100, for example, the first space portion 30 from the toe side is preferably arranged along the IP joint 201 and the PIP joint 203. Also, for example, the second space portion 30 from the toe side is preferably arranged along the MP joint 204. Also, for example, the fourth space portion 30 from the toe side is preferably arranged along the Lisfranc joint 205. Note that the space portions 30 do not need to be arranged strictly along the joints of the foot bones 200, but only need to be arranged to an extent that improves the flexion effect of the fishing shoe 100. The fishing shoes 100 have the space portions 30 arranged along the joints of the foot bones 200, which allows the fishing shoes 100 to easily bend in accordance with the bending of the joints of the foot bones 200. This makes walking even easier.

[0036] As shown in Figures 1 and 4, it is preferable that the fishing shoes 100 have, between adjacent bases 20, either or both of auxiliary protrusions 50 that protrude from the ground surface 11 and are taller than the bases 20, and auxiliary protrusions 60 that protrude from the ground surface 11 and are shorter than the bases 20.

[0037] As shown in FIG. 1, in this embodiment, the fishing shoes 100 have auxiliary protrusions 50 (see also FIG. 6) that are taller than the bases 20 between adjacent bases 20 in the second and fourth rows of base groups 20G from the toe side. Because the height of the auxiliary protrusions 50 is higher than that of the bases 20, the fishing shoes 100 are less likely to slip even when they come into contact with uneven ground, such as rocky terrain. Furthermore, by properly positioning the bases 20 and auxiliary protrusions 50 in relation to the uneven ground, the pressure on the bases 20 is reduced, making the bases 20 less likely to be damaged and improving their durability. Here, the height of the auxiliary protrusions 50 is set to be higher than that of the bases 20, but the height of the auxiliary protrusions 50 may be the same as that of the bases 20. The height H4 of the auxiliary protrusions 50 is, for example, 5.2 to 6.2 mm. The area of ​​the end face of the auxiliary protrusions 50 is smaller than that of the end face of the base 20.

[0038] Furthermore, as shown in FIG. 1, in this embodiment, the fishing shoes 100 have auxiliary protrusions 60 (see also FIG. 7) that are lower in height than the bases 20 between adjacent bases 20 in the third and fifth rows of base groups 20G from the toe side. Because the height of the auxiliary protrusions 60 is lower than that of the bases 20, the fishing shoes 100 are less likely to slip even when coming into contact with uneven ground, such as rocky terrain. Furthermore, by properly positioning the bases 20 and auxiliary protrusions 60 in relation to the uneven parts of the ground, the pressure on the bases 20 is reduced, making the bases 20 less likely to be damaged and improving their durability. The height H5 of the auxiliary protrusions 60 is, for example, 3.0 to 4.0 mm. The area of ​​the end face of the auxiliary protrusions 60 is smaller than the area of ​​the end face of the base 20. The auxiliary protrusions 50, 60 may have different shapes in plan view depending on where they are disposed.

[0039] The auxiliary protrusions 50, 60 are formed integrally with the sole 10. The auxiliary protrusions 50, 60 are made of the same material as the sole 10. The auxiliary protrusions 50, 60 are formed in a truncated cone shape so that the side surfaces are inclined inward in the direction of protrusion from the sole 10 in a cross-sectional view. That is, the auxiliary protrusions 50, 60 are formed in a columnar shape tapering toward the tip in the direction of protrusion from the sole 10. The auxiliary protrusions 50, 60 are, for example, approximately triangular or approximately hexagonal in a plan view. In this embodiment, the auxiliary protrusions 50, 60 are both approximately triangular and approximately hexagonal. By making the auxiliary protrusions 50, 60 approximately triangular or approximately hexagonal in a plan view, the fishing shoe 100 makes it easier to arrange the base 20 and the auxiliary protrusions 50, 60 on the sole 10 and to ensure the space portion 30.

[0040] The auxiliary protrusions 50, 60 are slightly curved and rounded so that their vertices are outwardly convex in plan view. The auxiliary protrusions 50, 60 are slightly curved and rounded so that their sides are inwardly convex in plan view. One vertex of each auxiliary protrusion 50, 60 faces the heel, and one side faces the toe. This allows the auxiliary protrusions 50, 60 to be positioned approximately 180 degrees rotated relative to adjacent bases 20 in plan view. That is, the auxiliary protrusions 50, 60 are positioned such that one vertex faces in the opposite direction and one side faces in the opposite direction relative to adjacent bases 20 in plan view. This configuration allows the bases 20 to be positioned to eliminate unnecessary space on the ground contact surface 11 of the sole 10, thereby increasing the size of the bases 20. This improves the durability of the bases 20. Furthermore, by enlarging the base 20, the area of ​​the base 20 that comes into contact with the ground can be increased, which provides better support when walking, makes it less likely to slip, and makes walking easier. In this embodiment, the base group 20G, including the auxiliary protrusions 50 and 60, is arranged in a curved shape so as to be convex toward the toe side when viewed in a plan view.

[0041] The fishing shoe 100 may have a base group 20G in the heel region HR. In this embodiment, the fishing shoe 100 has a series of base groups 20G in the heel region HR, which are made up of multiple bases 20 protruding from the ground surface 11 and arranged in the width direction. The base groups 20G are arranged in a curved shape so that they are convex toward the heel when viewed in a plane. By having the base groups 20G in the heel region HR, the fishing shoe 100 is less likely to slip and is easier to walk in.

[0042] Although the embodiments of the present invention have been specifically described above, the scope of the present invention is not limited to these descriptions and should be broadly interpreted based on the claims. Furthermore, various changes and modifications based on these descriptions are also included in the scope of the present invention.

[0043] For example, the fishing shoes 100 may have felt on the sole 10. The number of space portions 30 may be one or five or more. The base 20 and auxiliary protrusions 50, 60 may be substantially square, hexagonal, or circular in plan view. Note that the terms "substantially square" and "substantially hexagonal" are not limited to square and hexagonal shapes, respectively, and may include shapes with rounded corners and shapes with curved sides, for example. The term "substantially circular" is not limited to circular shapes and may also include oval shapes. The base 20 may not have a protruding pin 40. The fishing shoes 100 may not have auxiliary protrusions 50, 60. The fishing shoes 100 may have a space portion 30 in the heel region HR. [Explanation of symbols]
