Abstract
Description
Technical Field
[0001] The present invention relates to a shoe sole and a shoe provided with the shoe sole that can be effectively used particularly when entering water and performing stationary fishing in a slippery stream or when moving in water.
Background Art
[0002] As described above, when entering water and performing stationary fishing or when moving in water, the shoe sole is made of felt to prevent slipping. However, in order to make it even more difficult to slip, there has been proposed a structure in which spikes that bite into the surface of rocks and stones penetrate the entire shoe sole (see, for example, Patent Document 1).

Summary of the Invention
Problems to be Solved by the Invention
[0004] In the configuration of Patent Document 1 above, since the spikes are provided over the entire shoe sole, it is difficult to slip during stationary fishing or movement. However, when standing still, there is a problem that the upward push from the spikes is constantly transmitted to the sole of the foot, causing discomfort. On the other hand, if the shoe sole has no spikes at all, the grip force of the shoe sole during movement decreases, making it easy to slip. Therefore, it is impossible to eliminate the spikes, and early improvement is desired.
[0005] The present invention has been made in view of the above situation, and an object thereof is to provide a shoe sole and a shoe provided with the shoe sole that can ensure the grip force during movement while suppressing the upward push when standing still.
Means for Solving the Problems
[0006] The sole of the present invention comprises a felt sole body attached to the bottom of the shoe body, and a plurality of anti-slip devices provided on the sole body, the sole body having a first region on which the plurality of anti-slip devices are provided, and a second region different from the first region, the sole body defining a total length line which is the longest line connecting the toe side end to the heel side end, a width direction perpendicular to the total length line, the total inner width from the total length line to the inner end in the width direction, and the total outer width from the total length line to the outer end in the width direction, the second region being located at a position 89% of the length of the total length line from the heel side end The sole is characterized by having a first section defined by a first line extending in the width direction, a second line extending in the width direction at a position 68% of the length of the overall length from the heel side end, a third line extending parallel to the overall length at a position 45% of the total inner width from the overall length in the width direction at a position 77% of the length of the overall length from the heel side end of the sole body, and a fourth line extending parallel to the overall length at a position 55% of the total outer width from the overall length in the width direction perpendicular to the overall length at a position 77% of the length of the overall length from the heel side end of the sole body.
[0007] As a result of many years of diligent research, the inventors of this application have found that the problem can be solved by having the first section in a second region that is different from the first region. The first section in the second region is usually the area where the wearer's weight acts most intensely. By making this first section a different region from the first region, the upward thrust caused by the anti-slip device is eliminated, and the overall upward thrust when standing can be suppressed.
[0008] Furthermore, the sole of the present invention may further have a second section defined by a fifth line extending in a width direction perpendicular to the overall length line at a position 35% of the length of the overall length line from the heel side edge, and a sixth line extending in a width direction perpendicular to the overall length line at a position 9% of the length of the overall length line from the heel side edge.
[0009] The second section of the second region described above is typically the area where the wearer's weight is concentrated. By adding a second section in addition to the first section, the upward thrust caused by the anti-slip material is eliminated, and the overall upward thrust when standing can be suppressed.
[0010] Furthermore, the sole of the present invention may have a third section in the first region defined by the second line and the fifth line.
[0011] The third section corresponds to the arch of the wearer's foot. If an anti-slip device is provided in this third section, the device will grip the ground (such as rocks) it comes into contact with during movement, improving grip.
[0012] Furthermore, in the sole of the present invention, the contact tips of the plurality of anti-slip devices may be positioned closer to the shoe body than the contact surface of the sole body.
[0013] As described above, if the contact points of multiple anti-slip devices are positioned closer to the shoe body than the contact surface of the sole itself, the upward impact can be further suppressed. Moreover, when moving on a flat surface, the contact surface of the sole can reliably grip the flat surface, making it less likely to slip.
[0014] Furthermore, in the present invention, the felt may be composed of wool fibers.
[0015] Furthermore, in the present invention, the felt may be composed of polypropylene fibers.
[0016] Furthermore, the present invention may also involve a felt thickness of 10 millimeters or more.
[0017] Furthermore, the present invention may also be a shoe equipped with the aforementioned sole. [Effects of the Invention]
[0018] As described in the present invention, by providing a configuration in which the portion of the sole that experiences significant impact has a second region different from the first region, it is possible to provide a sole and shoes equipped with such a sole that can suppress impact when standing while ensuring grip during movement.

Embodiments for Carrying Out the Invention
[0020] Hereinafter, embodiments of the present invention will be described based on the drawings.
[0021] FIG. 1 shows a shoe A having a shoe body 1 into which a foot is inserted, a bottom body portion 2 attached to the bottom (bottom surface) of the shoe body 1 by an adhesive S or the like, and a plurality (only one is shown in FIG. 1) of anti-slip devices 3 (see FIG. 2) embedded in the bottom body portion 2. The bottom body portion 2 includes an outsole 21 located on the ground contact side and a midsole 22 fixed to the upper surface of the outsole 21 by an adhesive or the like. Incidentally, the sole 4 may be detachably attached to the bottom surface (lower surface) of the shoe body 1 by a hook-and-loop fastener (not shown) so that the sole 4 can be replaced.
[0022] The outsole 21 is made of felt and has a thickness of 10 millimeters or more. Particularly preferably it is 12 millimeters thick. Specifically, the outsole 21 is made of wool fibers, polypropylene fibers, etc., and has a nearly flat contact surface and an outer shape that matches the shape of a foot (see Figure 2). Wool fibers have a scale-like surface structure that opens up when they absorb moisture, forming a fine uneven surface, which improves slip resistance on wet rocks and riverbeds, but they are prone to wear. In contrast, synthetic fibers such as polypropylene fibers are less prone to wear and have excellent durability. The midsole 22 is formed in the same outer shape as the outsole 21 and matches the shape of a foot, and is thinner than the thickness of the outsole 21, but may be the same thickness. As the material for forming the midsole 22, lightweight foamed EVA with excellent cushioning (shock absorption) is used, but it can also be made from other materials.
[0023] The anti-slip device 3 is made of various metals and, as shown in Figures 3(a) and (b), is constructed by bending a rod-shaped member with a circular cross-section to form a spike pin with a roughly U-shape in side view. Specifically, it comprises a horizontal portion 31 and straight vertical portions 32, 32, each of which is bent at 90 degrees at both ends of the horizontal portion 31. The horizontal portion 31 is formed in a roughly inverted S-shape in the plan view shown in Figure 3(b). A pair of holes 21A, 21A (see Figure 1) are formed in the outsole 21 through which a pair of vertical portions 32, 32 of multiple anti-slip devices 3 can be inserted. Multiple anti-slip devices 3 are embedded in the bottom body portion 2 by inserting the vertical portions 32, 32 of the multiple anti-slip devices 3 into the holes 21A, 21A of the outsole 21 and joining the outsole 21 to the midsole 22 while pressing the horizontal portion 31 of the anti-slip device 3 against the bottom surface of the midsole 22.
[0024] The contact tips 32A, 32A of the vertical parts 32, 32 of the embedded anti-slip devices 3 are positioned closer to the shoe body 1 than the contact surface 21A of the outsole 21 that constitutes the bottom body 2 (see Figure 1). Specifically, the distance between the contact tips 32A, 32A of the vertical parts 32, 32 and the contact surface 21B of the outsole 21 is set to, for example, 0.7 mm, but it may be set to any value in the range of 0.3 mm to 1.3 mm, preferably any value in the range of 0.5 mm to 1 mm. This setting is preferably changed depending on the material of the outsole 21. For example, if the outsole 21 is made of wool fiber, it is preferable to set it to any value in the range of 0.5 mm to 1.3 mm, and if the outsole 21 is made of synthetic fiber such as polypropylene fiber, it is preferable to set it to a smaller value than in the case of wool fiber, i.e., any value in the range of 0.3 mm to 1 mm, because it is less prone to wear than wool fiber. As a result, regardless of the material of the outsole 21, the wear of the outsole 21 progresses faster than the wear of the anti-slip device 3, and the contact tips 32A, 32A of the vertical parts 32, 32 of the anti-slip device 3 protrude from the contact surface of the outsole 21 toward the ground.
[0025] The orientation of the multiple anti-slip devices 3 (the direction of the straight line connecting the vertical parts 32, 32 shown in Figure 2) is random, rather than being oriented in a fixed (same) direction.
[0026] As mentioned above, if the contact tips 32A, 32A of the vertical parts 32, 32 of the multiple anti-slip devices 3 are positioned closer to the shoe body 1 than the contact surface 21B of the outsole 21, the impact can be further suppressed. Moreover, when moving on a flat surface, the contact surface 21B of the outsole 21 can reliably grip the flat surface, making it less likely to slip. As the shoe is used, the contact surface 21B of the outsole 21 wears down, causing the contact tips 32A, 32A of the vertical parts 32, 32 of the anti-slip devices 3 to gradually move closer to the contact surface 21B, allowing the anti-slip devices 3 to exert their grip effectively. In short, the shoe can be made just right as it is used.
[0027] In the present invention, the bottom body portion 2 comprises a first region 5 having a plurality of anti-slip devices 3, and a second region 6 different from the first region 5, that is, a region without anti-slip devices 3.
[0028] Here, as shown in Figures 4 and 5, the sole body 2 defines the overall length line 9, which is the longest line connecting the toe end 7 to the heel end 8, the width direction perpendicular to the overall length line 9, the total inner width 10 from the overall length line 9 to the inner end in the width direction, and the total outer width 11 from the overall length line 9 to the outer end in the width direction, and then specifies the first region 5 and the second region 6. Note that Figure 4 shows two types of sole body 2,2 with different external shapes.
[0029] Specifically, the second region 6 has a first section 61 defined by a first line 12 extending in the width direction from the heel end 8 at a position 89% of the length of the total length line 9, a second line 13 extending in the width direction from the heel end 8 at a position 68% of the length of the total length line 9, a third line 14 (see Figure 5) extending parallel to the total length line 9 in the width direction from the total length line 9 at a position 45% of the total inner width 10 at a position 77% of the length of the total length line 9 from the heel end 8 of the sole body 2, and a fourth line 15 (see Figure 5) extending parallel to the total length line 9 in the width direction perpendicular to the total length line 9 in the width direction at a position 55% of the total outer width 11 from the total length line 9 at a position 77% of the length of the total length line 9 from the heel end 8 of the sole body 2. The point 68% of the length from the heel side edge 8 to the total length line 9 corresponds to the sesamoid bone (ball of the foot) 20 shown in Figure 6, and is said to be a part that receives a lot of pressure from the contact surface.
[0030] Furthermore, as shown in Figure 4, the second region 6 further comprises a second section 62 defined by a fifth line 16 extending in the width direction perpendicular to the overall length line 9 at a position 35% of the length of the overall length line 9 from the heel side end 8, and a sixth line 17 extending in the width direction perpendicular to the overall length line 9 at a position 9% of the length of the overall length line 9 from the heel side end 8.
[0031] With respect to the second region 6, the first region 5 has a third section 51 (see Figure 4) defined by the second line 13 and the fifth line 16.
[0032] Furthermore, as shown in Figure 4, the first region 5 further comprises a fourth section 52 between the first line 12 and the toe end 7, and a fifth section 53 between the heel end 8 and the sixth line 17. Moreover, the first region 5 also comprises a sixth section 54 enclosed by the first line 12, the third line 14, the second line 13 and the inner end in the width direction, and a seventh section 55 enclosed by the first line 12, the fourth line 15, the second line 13 and the outer end in the width direction.
[0033] As shown in Figure 6, the first compartment 61 corresponds to the area of the second proximal phalanx 18 and the third proximal phalanx 19 of the foot, the second compartment 62 corresponds to the area of the calcaneus 40 and the talus 41 of the foot, and the third compartment 51 corresponds to the area of the cuneiform bone 42, navicular bone 43, and cuboid bone 44.
[0034] Furthermore, Figure 6 shows the two points (toe side and heel side) where weight is applied during the pressure test. On the toe side, the central 1A pressure-sensitive area 45 is the area where the most weight is applied and the reaction force from the contact surface acts on the sole of the foot most strongly. The 2A pressure-sensitive area 46, located outside the 1A pressure-sensitive area 45, is the area where the second most weight is applied and the reaction force from the contact surface acts on the sole of the foot with the second greatest magnitude. The 3A pressure-sensitive area 47, located outside the 2A pressure-sensitive area 46, is the area where the third most weight is applied and the reaction force from the contact surface acts on the sole of the foot with the third greatest magnitude. The 4A pressure-sensitive area 48, located outside the 3A pressure-sensitive area 47, is the area where the fourth most weight is applied and the reaction force from the contact surface acts on the sole of the foot with the fourth greatest magnitude. Furthermore, the 5A pressure-sensitive area 49, located outside the 4A pressure-sensitive area 48, is the area where the fifth most weight is applied and where the reaction force from the contact surface acts on the sole of the foot with the fifth greatest magnitude. However, because the reaction force is very small, the 5A pressure-sensitive area 49 is considered negligible. The area encompassing these four pressure-sensitive areas 45, 46, 47, and 48 (the area on the toe side of the sole body 2 where pressure is easily applied) corresponds to the first section 61 of the second area 6, and this first section 61 does not have an anti-slip device 3. As a result, the upward thrust caused by the anti-slip device 3 in the first section 61, where the wearer's weight is concentrated, is eliminated, and the overall upward thrust when standing is suppressed.
[0035] On the other side, the heel, the central 1B pressure-sensitive area 70 (a smaller area than the 1A pressure-sensitive area 45) is the area where the most weight is applied and the greatest reaction force from the contact surface acts on the sole of the foot. The 2B pressure-sensitive area 71, located outside the 1B pressure-sensitive area 70, is the area where the second most weight is applied and the reaction force from the contact surface acts on the sole of the foot with the second greatest magnitude. The 3B pressure-sensitive area 72, located outside the 2B pressure-sensitive area 71, is the area where the third most weight is applied and the reaction force from the contact surface acts on the sole of the foot with the third greatest magnitude. The 4B pressure-sensitive area 73, located outside the 3B pressure-sensitive area 72, is the area where the fourth most weight is applied and the reaction force from the contact surface acts on the sole of the foot with the fourth greatest magnitude. Furthermore, the 5B pressure-sensitive area 74, located outside the 4B pressure-sensitive area 73, is the area where the fifth most weight is applied and where the reaction force from the contact surface acts on the sole of the foot with the fifth greatest magnitude. However, because the reaction force is very small, the 5B pressure-sensitive area 74 is considered negligible. The area encompassing these four pressure-sensitive areas 70, 71, 72, and 73 (the area on the heel side of the sole body 2 where pressure is easily applied) is the second section 62 of the second area 6, and this second section 62 does not have an anti-slip device 3. As a result, the upward thrust caused by the anti-slip device 3 in the second section 62, where the wearer's weight is concentrated, is eliminated, and the overall upward thrust when standing is suppressed.
[0036] The soles and shoes of the present invention are not limited to the embodiments described above.
[0037] In the above embodiment, both the first section 61 and the second section 62 were made without anti-slip devices 3, but it is also possible for only the first section 61 to be made without anti-slip devices 3.
[0038] Furthermore, although the anti-slip device 3 was made of metal in the above embodiment, it may also be made of synthetic resin, synthetic rubber, or the like. Also, although the anti-slip device 3 was made by bending a rod-shaped member, it can also be made from, for example, a rectangular plate-shaped member.
[0039] Furthermore, in the above embodiment, the contact tips 32A, 32A of the anti-slip device 3 were positioned closer to the shoe body than the contact surface 21B of the sole body 2, but the contact tips 32A, 32A of the anti-slip device 3 may be positioned at the same position as the contact surface 21B of the sole body 2.
