Description

TECHNICAL FIELD

[0001] The present application relates to a fishing shoe. BACKGROUND

[0002] For example, in Patent Literature 1, there is disclosed a fishing shoe in which a sole is fixed to the bottom surface of a shoe body, and the sole has a plurality of pin-shaped protrusions and a plurality of plate-shaped protrusions disposed between each pin-shaped protrusion and the periphery of the sole. With this configuration, even in a fishing site having unevenness such as bare rock, the fishing shoe of Patent Literature 1 is less likely to slip.

[0003] PATENT LITERATURE Patent Literature 1: Japanese Patent Application Publication No. 2011-177069 SUMMARY

[0004] In walking, a fishing shoe lands in the order of the heel, the sole (the instep), and the toe, and then comes off the ground. The above-described conventional fishing shoe has a thick sole and plate-shaped protrusions disposed on the periphery of the sole, and thus the sole is less likely to bend. Therefore, the conventional fishing shoe has room for improvement in terms of facilitating walking.

[0005] In view of the above-described background, it is an object of the present application to provide a fishing shoe that is less likely to slip and easily bends along the user's foot joints, and thus facilitates walking.

[0006] To achieve the above-described object, a fishing shoe according to the present application is characterized in that, in a sole having a toe side region and a heel side region, and in the toe side region, protrusions protruding from the sole are formed as a plurality of protrusion groups disposed along an imaginary bending line in a width direction of the sole, a plurality of rows of the protrusion groups are disposed in a length direction of the toe side region, and between two protrusion groups adjacent in the length direction, a space portion in which the protrusions are not present and in which bending is approximately the same as the imaginary bending line in the width direction is formed.

[0007] In one embodiment, it is characterized in that, in the length direction of the sole, at least three rows of the protrusion groups are disposed, and at least two of the space portions are disposed.

[0008] In one embodiment, it is characterized in that the protrusions are triangular or hexagonal in plan view of the sole.

[0009] In one embodiment, it is characterized in that, between two protrusions adjacent to each other, either of an auxiliary protrusion protruding from the sole and being higher or lower than the protrusions is further provided.

[0010] In one embodiment, characterized in that a protruding pin protruding from the end surface of the protruding portion is further provided on the protruding portion.

[0011] According to the present application, since the protruding portion groups provided with a plurality of protruding portions are formed along the imaginary curved line provided at the toe side, and between the two protruding portion groups adjacent in the length direction, a space portion in which no protruding portion exists and which is approximately curved with the imaginary curved line is formed, it is easy to bend in cooperation with the bending of the joints of the bones of the foot of the user, and thus a fishing shoe which is easy to walk and not easy to slip can be provided.

DETAILED DESCRIPTION

[0013] The following description, with reference to the accompanying drawings, illustrates one embodiment of the present invention. Furthermore, the configuration shown below exemplifies a fishing shoe for implementing the technical concept of the present invention and is not limited to the specific configuration of the embodiment. Additionally, the dimensions, materials, shapes, and relative arrangements of the constituent parts described in the embodiment are merely illustrative unless specifically stated otherwise, and the scope of the present invention is not limited thereto. Moreover, for clarity, the size or positional relationships of the components shown in the drawings may sometimes be exaggerated or simplified, and some elements have been omitted to avoid making the drawings overly complex.

[0014] Figure 1 This is a diagram showing the fishing shoes involved in this embodiment as viewed from the surface. Figure 1 In this context, the front side is the toe side, the back side is the heel side, the left side is the inside, and the right side is the outside.

[0015] like Figure 1 and Figure 2 As shown, the fishing shoe 100 is configured to include: a shoe body 1 that covers the foot; and a sole (shoe bottom) 10 that is glued and fixed to the shoe body 1. The sole 10 has an outer sole 2 and a middle sole 3.

[0016] The shoe body 1 is made of materials such as cloth, leather, or rubber, and a sole 10 with a specified wall thickness is fixed to its back (bottom) surface by means of bonding or the like. Examples of materials for the sole 10 include synthetic resins such as rubber, polyurethane, and EVA.

[0017] like Figure 1 As shown, the fishing shoe 100 has multiple rows of protrusions 20G formed on the sole surface 11 of the sole 10, which has a toe side region TR and a heel side region HR, and on the toe side region TR in the front-back direction. The protrusions 20G are configured to protrude from the sole surface 11 and have multiple protrusions 20 along an imaginary curved line L2 in the width direction.

[0018] Between the front protrusion group 20G and the rear protrusion group 20G adjacent in the front-rear direction, an imaginary curved line L1 is formed along the width direction of the imaginary curved line L2 of the protrusion group 20G, where there is no protrusion 20. In the top view of the sole 10, the imaginary curved lines L2 and L1 are curved lines that bulge forward.

[0019] In this embodiment, the ratio Figure 1 The area further forward of the AA line is defined as the toe-side region (TR), and the area further back than the AA line is defined as the heel-side region (HR). Additionally... Figure 1 The AA line is the part that corresponds to the arch of the foot when the wearer is wearing it.

[0020] In the toe-side region TR, the protrusion group 20G is composed of a plurality of protrusions 20 integrally formed with the sole 10. The material of the protrusions 20 can be the same as that of the sole 10. The protrusions 20 protrude from the sole surface 11 in the toe-side region TR. In the toe-side region TR, a plurality of protrusions 20 constituting the protrusion group 20G are provided along an imaginary curved line L2 in the width direction of the sole 10. In this embodiment, three or four protrusions 20 are provided.

[0021] The protrusion 20 is formed into a frustum shape, with its sides inclined in the direction of protrusion from the sole 10 when viewed in cross-section in the thickness direction. That is, the protrusion 20 has a shape that tapers at the apex in the direction of protrusion from the sole 10. Furthermore, the sides of the protrusion 20 are curved inwardly when viewed from above.

[0022] The protrusion 20a located on the inside of the fishing shoe 100 (refer to) Figure 1 The protrusion 20c extends to the inner side of the fishing shoe 100, and the shape of the protrusion 20a extending to the outer side of the fishing shoe 100 is also an extension to the outer side of the fishing shoe 100. The protrusion 20b located between the protrusions 20a and 20c is triangular or hexagonal in plan view. The triangle is not limited to a precise triangle, and may also include shapes with rounded corners or curved sides. Similarly, the hexagon is not limited to a precise hexagon, and may also include shapes with rounded corners or curved sides. In addition, the protrusions 20a and 20b are also triangular or hexagonal in plan view. By making the protrusions 20 triangular or hexagonal in plan view, the fishing shoe 100 facilitates the placement of the protrusions 20 and the auxiliary protrusions 50 and 60 (described later) on the sole 10, and easily ensures the space 30. The plan view shape of the protrusions 20 may also vary depending on the placement location.

[0023] Figure 3 yes Figure 2 An enlarged view of the part marked B. (e.g.) Figure 3As shown, the fishing shoe 100 includes a protruding pin 40, partly embedded inside a protrusion 20 and protruding from the end face 20x of the protrusion 20. The protruding pin 40 has a flat portion 41, a first protrusion 42, and a second protrusion 43. The flat portion 41 is circular in plan view, and for example, disc-shaped. The flat portion 41 is disposed inside the sole 10. The first protrusion 42 is integrally formed with the flat portion 41 and protrudes from the end face 20x of the protrusion 20 while standing upright from the flat portion 41. A portion of the first protrusion 42 is disposed inside the protrusion 20, and a portion protrudes from the end face 20x of the protrusion 20. The second protrusion 43 is, for example, embedded in a recess formed on the end face 42x of the first protrusion 42 and protrudes from the end face 42x of the first protrusion 42. By including the protruding pin 40, the fishing shoe 100 becomes less slippery. In addition, it is not easy to damage the protrusion 20, which can improve the durability of the protrusion 20.

[0024] The flat plate portion 41 and the first protrusion 42 are, for example, made of stainless steel. Making the flat plate portion 41 and the first protrusion 42 of stainless steel increases their strength. The second protrusion 43 is, for example, made of tungsten. Making the second protrusion 43 of tungsten further increases its strength. The height H1 of the protrusion 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 protrusion 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. When manufacturing the sole 10, the protruding pin 40 can be formed, for example, by insert molding.

[0025] like Figure 1 As shown, the sole 10 has a group of protrusions 20G arranged in multiple rows along its length. In this embodiment, five rows of protrusions 20G are arranged in the toe-side region TR of the fishing shoe 100. Furthermore, the two adjacent protrusions of the topmost protrusion 20 on the toe-side are integrated, and each protrusion 20 has two protruding pins 40. In this embodiment, the topmost protrusion 20 is not included in the protrusion group 20G. However, as long as the required space 30 can be ensured, the topmost protrusion 20 can be considered as two protrusions and included in the protrusion group 20G.

[0026] As previously described, the protruding group 20G and the spatial portion 30 are configured to curve and bulge towards the toes when viewed from above. The curvature of the protruding group 20G and the spatial portion 30 can be either an arc or another quadratic curve. Figure 1For convenience, the curvature of the space portion 30 is represented by an imaginary curved line L1. Furthermore, the curvature of the protrusion group 20G refers, for example, to a curved line passing through the center of the protrusion 20 or its vicinity, such as the line passing through the protruding pin 40. Figure 1 For convenience, the curvature of the protrusion group 20G is represented by an imaginary curved line L2. The curvature of the protrusion group 20G and the space portion 30 are, for example, of a certain curvature. In top view, the apex of the protrusion 20 has rounded corners and is slightly curved, protruding outwards. Furthermore, in top view, the edges of the protrusion 20 have rounded corners and are slightly curved, protruding inwards. Moreover, one apex of the protrusion 20 faces the toe side, and one edge faces the heel side. Therefore, it is easy to configure the space portion 30 in a curved shape protruding towards the toe side without interfering with the protrusion 20. Since the fishing shoe 100 has the space portion 30, the fishing shoe 100 can easily bend in the space portion 30. This facilitates walking.

[0027] Preferably, at least two or more space portions 30 are provided in the toe-side region TR, and protrusion groups 20G and space portions 30 are alternately arranged in the fore-and-aft direction of the sole 10. In this embodiment, the fishing shoe 100 has five protrusion groups 20G and four space portions 30 alternately arranged in the toe-side region TR of the sole 10 in the fore-and-aft direction. The four space portions 30 are arranged at approximately equal intervals in the fore-and-aft direction of the fishing shoe 100. By providing multiple space portions 30, the fishing shoe 100 becomes more flexible at multiple space portions 30, making it easier to walk. The degree of flexibility of the four space portions 30 is different. In this embodiment, the curvature (degree of flexibility) is greater towards the rear of the fishing shoe 100. In addition, as will be described later, the degree of flexibility of the first and second space portions 30 from the front is adjusted to better match the joints of the user's foot bones 200.

[0028] Preferably, the space 30 is designed and configured along the joints of the average user's foot bones 200. For example... Figure 5 As shown, the human foot bone 200 includes joints such as IP 201, DIP 202, PIP 203, MP 204, and tarsometatarsal joint 205. Figure 5For convenience, an imaginary curved line L3 is used to illustrate the approximate bend that connects these joints to each other. For example, the fishing shoe 100 preferably has a first space 30 arranged along the IP joint 201 and PIP joint 203, starting from the toe side. Furthermore, for example, a second space 30 is preferably arranged along the MP joint 204, starting from the toe side. Furthermore, for example, a fourth space 30 is preferably arranged along the tarsometatarsal joint 205, starting from the toe side. Additionally, it is sufficient to design the space 30 to be arranged along the joints of the average user's foot bones 200, and to a degree that improves the bending effect of the fishing shoe 100 for the average user. By arranging the space 30 of the fishing shoe 100 along the joints of the user's foot bones 200, the fishing shoe 100 can easily bend in accordance with the bending of the joints of the foot bones 200, making walking easier.

[0029] like Figure 1 and Figure 4 As shown, the preferred fishing shoe 100 has either or both of the following: an auxiliary protrusion 50 that protrudes from the sole 11 and is higher than the protrusion 20, and an auxiliary protrusion 60 that protrudes from the sole 11 and is lower than the protrusion 20, between adjacent protrusions 20.

[0030] like Figure 1 As shown, in this embodiment, the fishing shoe 100 has an auxiliary protrusion 50 that is higher than the protrusion 20 between adjacent protrusions 20 in the protrusion groups 20G from the toe side (see also...). Figure 6 Because the height of the auxiliary protrusion 50 is greater than the height of the protrusion 20, the fishing shoe 100 is less likely to slip even when in contact with uneven ground, such as bare rock. Furthermore, since the uneven parts of the ground are cleverly offset from the positions of the protrusion 20 and the auxiliary protrusion 50, the pressure applied to the protrusion 20 is reduced, making it less likely to be damaged and improving its durability. However, while the height of the auxiliary protrusion 50 is greater than that of the protrusion 20, it can also be the same. The height H4 of the auxiliary protrusion 50 is, for example, 5.2 to 6.2 mm. The top view area of ​​the end face of the auxiliary protrusion 50 is smaller than that of the end face of the protrusion 20.

[0031] In addition, such as Figure 1 As shown, in this embodiment, the fishing shoe 100 has an auxiliary protrusion 60, which is lower in height than the protrusion 2, disposed between adjacent protrusions 20 in the third and fifth rows of protrusion groups 20G from the toe side (see also...). Figure 7). Since the height of the auxiliary protrusions 60 is lower than the height of the protrusions 20, the fishing shoe 100 is less likely to slip even when coming into contact with a ground surface having unevenness such as bare rock. Moreover, since the positions of the unevenness of the ground surface and the positions of the protrusions 20 and the auxiliary protrusions 60 are ingeniously staggered, the pressure applied to the protrusions 20 can be reduced, the protrusions 20 are less likely to be damaged, and the durability of the protrusions 20 can be improved. The height H5 of the auxiliary protrusions 60 is, for example, 3.0 to 4.0 mm. The area of the end surface of the auxiliary protrusions 60 is smaller than the area of the end surface of the protrusions 20. The planar shapes of the auxiliary protrusions 50 and 60 can also be different from each other depending on the configuration site.

[0032] The auxiliary protrusions 50 and 60 are formed integrally with the sole 10. The same material as that of the sole 10 can be used as the material of the auxiliary protrusions 50 and 60. In a cross-sectional view, the auxiliary protrusions 50 and 60 are formed in a frustum shape in such a manner that the side surface is inclined inward toward the direction in which the sole 10 protrudes. That is, the auxiliary protrusions 50 and 60 are formed in a columnar shape in which the tip end is tapered toward the direction in which the sole 10 protrudes. In a planar view, the auxiliary protrusions 50 and 60 are, for example, triangular or hexagonal. In the present embodiment, the auxiliary protrusions 50 and 60 are both triangular and hexagonal. The fishing shoe 100 can facilitate the arrangement of the protrusions 20 and the auxiliary protrusions 50 and 60 on the sole 10 and easily secure the space portions 30 by making the auxiliary protrusions 50 and 60 triangular or hexagonal in a planar view.

[0033] In a planar view, the tip end portions of the auxiliary protrusions 50 and 60 are rounded and slightly curved in such a manner that they protrude outward. Moreover, in a planar view, the side portions of the auxiliary protrusions 50 and 60 are rounded and slightly curved in such a manner that they protrude inward. Furthermore, one of the tip end portions of the auxiliary protrusions 50 and 60 faces the heel side, and one of the side portions faces the toe side. Thus, the auxiliary protrusions 50 and 60 are arranged in such a manner that they are rotated by about 180 degrees with respect to the adjacent protrusions 20 in a planar view. That is, in a planar view, the tip end portions of the auxiliary protrusions 50 and 60 are arranged in opposite directions to each other with respect to the adjacent protrusions 20, and the side portions of the auxiliary protrusions 50 and 60 are arranged in opposite directions to each other with respect to the adjacent protrusions 20. By adopting such a configuration, the protrusions 20 can be arranged on the sole surface 11 of the sole 10 in such a manner that useless areas are eliminated, and the protrusions 20 can be increased in size. Thus, the durability of the protrusions 20 can be improved. Moreover, by increasing the size of the protrusions 20, the area of the protrusions 20 in contact with the ground surface can be increased, the effect of stepping on the ground surface during walking can be improved, the shoe is less likely to slip, and walking can be facilitated. In the present embodiment, in a planar view, the protrusion groups 20G and the auxiliary protrusions 50 and 60 are arranged in a curved shape in such a manner that they protrude toward the toe side.

[0034] The fishing shoe 100 can have or can not have the protrusion group 20G in the heel side region HR, but in the present embodiment, an example is shown in which the protrusion group 20G composed of a plurality of protrusions 20 protruding from the sole surface 11 and arranged in the width direction is provided in the heel side region HR. In plan view, the protrusion group 20G is arranged in a curved shape so as to protrude toward the heel side. By providing the fishing shoe 100 with the protrusion group 20G in the heel side region HR as well, slippage is less likely to occur, and walking is facilitated.

[0035] As described above, it is sufficient that the protrusions 20, the protrusion group 20G, and the space portion 30 are formed at least in the toe side region TR, and it is not necessarily required to be formed in the heel side region HR.

[0036] Although the modes for carrying out the present application have been specifically described above, the gist of the present application is not limited to these descriptions, and must be widely understood based on the description of the scope of the technical solution. Furthermore, the content of various modifications, changes, and the like based on these descriptions is also included in the gist of the present application.

[0037] For example, the fishing shoe 100 can also have a felt on the sole 10. Furthermore, the number of space portions 30 can be one or more than five. Furthermore, the protrusions 20 and the auxiliary protrusions 50, 60 can be angular shapes other than triangular and hexagonal shapes in plan view, and can further be circular or elliptical shapes. Furthermore, it is not necessarily required to provide the protrusions 20 with the protruding pins 40, and the auxiliary protrusions 50, 60 can also not be provided.
