Description

The present invention relates to a sole that can be used particularly effectively when entering the water in a slippery mountain stream for standing fishing or when moving in the water, and shoes equipped with the sole.

As mentioned above, the soles of the shoes are made of felt to prevent slipping when entering the water for stand-up fishing or moving in the water. A shoe shoe has been proposed in which spikes that penetrate into the surface of rocks, stones, etc. are provided over the entire area of the shoe sole (for example, see Patent Document 1).

Utility Model Registration No. 2561424 (see Figure 1)

In the configuration of Patent Document 1, the spikes are provided over the entire area of the sole, making it difficult to slip when standing fishing or moving, but when standing, the thrust from the spikes is constantly transmitted to the sole of the foot, making it uncomfortable. There was an inconvenience. On the other hand, if the shoe sole has no spikes at all, the grip of the sole during movement will be reduced and the shoe will become slippery, making it impossible to eliminate the spikes, and an early improvement is desired.

The present invention was made in view of the above-mentioned situation, and it is an object of the present invention to provide a sole and a shoe equipped with the sole that can ensure grip when moving while suppressing push-up when standing.

The sole of the present invention includes a sole body made of felt that is attached to the bottom of the shoe body, and a plurality of anti-slip devices provided on the sole body, and the sole body includes a plurality of anti-slip devices. The bottom main body has a first region where a tool is provided and a second region different from the first region, and the bottom main body portion has a full length line that is the longest line connecting the toe side end to the heel side end, and a full length line that is the longest line connecting the toe side end to the heel side end. A width direction perpendicular to the line, a total inner width from the full length line to the inner end in the width direction, and a total outer width from the full length line to the outer end in the width direction, and the second area is a first line extending in the width direction at a position of 89% of the length of the full length line from the heel side end, and a first line extending in the width direction at a position of 68% of the length of the full length line from the heel side end. a second line extending from the heel side end of the sole main body portion, and a full length line at a position 45% of the total inner width from the full length line in the width direction at a position of 77% of the length of the full length line from the heel side end of the sole body portion. a third line extending in parallel; and 55% of the total outer width from the full length line in the width direction perpendicular to the full length line at a position of 77% of the length of the full length line from the heel side end of the sole main body. %, a fourth line extending parallel to the full length line, and a first section defined by a fourth line extending parallel to the full length line.

As a result of extensive research over many years, the inventors of the present application have found that the problem can be solved by having the first section in a second region different from the first region. The first section of the second region is usually an area where the wearer's weight acts intensively, but by making this first section different from the first area, the push-up caused by the anti-slip device is eliminated. As a whole, it is possible to suppress uplift when standing.

Further, in the sole of the present invention, the second region includes a fifth line extending in the width direction perpendicular to the full length line at a position of 35% of the length of the full length line from the heel side end; The device may further include a second section defined by a sixth line extending in the width direction perpendicular to the full length line at a position of 9% of the length of the full length line from the end.

The second section of the second region is usually an area where the wearer's weight acts intensively, but by providing the second section in addition to the first section, the push-up by the anti-slip device is prevented. As a result, the thrusting up when standing up can be suppressed as a whole.

Moreover, in the sole of the present invention, the first region may have a third section defined by the second line and the fifth line.

The third section is an area corresponding to the arch of the wearer's feet, and if an anti-slip device is provided in this third section, the anti-slip device will lock onto the ground (rocky area, etc.) that it touches when moving. Improves grip strength.

Further, in the shoe sole of the present invention, the ground contact tips of the plurality of anti-slip devices may be located closer to the shoe main body than the ground contact surface of the sole main body.

As described above, if the ground contact tips of the plurality of anti-slip devices are located closer to the shoe body than the ground contact surface of the sole body, push-up can be further suppressed. Moreover, when moving on a flat surface, the contact surface of the sole of the shoe reliably grips the flat surface, making it difficult to slip.

Further, in the present invention, the felt may be made of wool fiber.

Further, in the present invention, the felt may be made of polypropylene fiber.

Further, in the present invention, the thickness of the felt may be 10 mm or more.

Moreover, the present invention may be a shoe including the sole.

As in the present invention, by configuring the sole of the shoe to have a second region different from the first region in the part of the shoe sole where the push-up is large, the push-up when standing is suppressed while the grip force when moving is increased. It is possible to provide a shoe with a secure sole and a shoe sole.

FIG. 1 is a partially cutaway side view of a shoe equipped with the sole of the present invention. It is a bottom view of the sole of the same shoe. The anti-slip device provided on the sole of the shoe is shown, with (a) being a front view and (b) being a plan view. These are bottom views of two types of shoe soles having different shapes. FIG. 5 is an enlarged view of a main part of the right shoe sole in FIG. 4; FIG. 5 is an explanatory diagram showing the relationship between the bones of the foot corresponding to the pressure-sensitive area of the sole of the right shoe in FIG. 4;

Embodiments of the present invention will be described below based on the drawings.

FIG. 1 shows a shoe body 1 into which a foot is inserted, a sole body part 2 attached to the bottom (bottom surface) of the shoe body 1 with adhesive S, and a plurality of shoes (one in FIG. 1) embedded in the sole body part 2. 2 shows a shoe A having a sole 4 having a non-slip device 3 (only shown in FIG. 2). The sole main body portion 2 includes an outsole 21 located on the side of the ground surface, and a midsole 22 fixed to the upper surface of the outsole 21 with an adhesive or the like. Note that the sole 4 may be detachably attached to the bottom surface (lower surface) of the shoe body 1 using a hook-and-loop fastener (not shown) so that the sole 4 can be replaced.

The outsole 21 has a thickness of 10 mm or more and is made of felt. Particularly preferred is 12 mm. Specifically, the outsole 21 is made of wool fiber, polypropylene fiber, etc., and has a substantially flat contact surface and a foot-shaped outer shape (see FIG. 2). The scaly surface structure of wool fibers absorbs water and opens up to form fine irregularities, which improves the slip resistance on wet rocky areas, riverbeds, etc., but is prone to wear. On the other hand, synthetic fibers such as polypropylene fibers are less likely to wear out and have excellent durability. The midsole 22 is formed in the same foot shape as the outsole 21, and is thinner than the outsole 21, but may have the same thickness. As the material forming the midsole 22, foamed EVA is used, which is lightweight and has excellent cushioning properties (impact cushioning properties), but it can also be composed of other materials.

The anti-slip tool 3 is made of various metals, and as shown in FIGS. 3(a) and 3(b), it is constructed by bending a rod-shaped member with a circular cross-section to form a spike pin that is approximately U-shaped when viewed from the side. There is. Specifically, it includes a horizontal portion 31 and linear 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 into a substantially inverted S-shape when viewed from above in FIG. 3(b). A pair of holes 21A, 21A (see FIG. 1) through which the pair of vertical parts 32, 32 of the plurality of anti-slip devices 3 can be inserted are formed in the outsole 21. By inserting the 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 devices 3 against the bottom surface of the midsole 22, the plurality of anti-slip devices 3 are inserted into the bottom surface of the midsole 22. It is buried in the main body part 2.

The ground contact tips 32A, 32A of the vertical parts 32, 32 of the plurality of embedded anti-slip devices 3 are located closer to the shoe body 1 than the ground contact surface 21A of the outsole 21, which constitutes the sole body 2 ( (see Figure 1). Specifically, the distance between the grounding tips 32A, 32A of the vertical parts 32, 32 and the grounding surface 21B of the outsole 21 is, for example, 0.7 mm, but it may be any distance in the range of 0.3 mm to 1.3 mm. It may be set to any value within the range of preferably 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 set to an arbitrary 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 set to an arbitrary value in the range of 0.5 mm to 1.3 mm. Since it is difficult to wear, it is preferable to set it to a smaller value than that of wool fibers, that is, an arbitrary value in the range of 0.3 mm to 1 mm. 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 portions 32, 32 of the anti-slip device 3 touch the outsole 21. It protrudes from the ground surface to the ground side.

The orientations of the plurality of anti-slip tools 3 (the direction of the straight line connecting the vertical parts 32, 32 shown in FIG. 2) are not oriented in a fixed (same) direction but are oriented randomly.

As mentioned above, if the ground contact tips 32A, 32A of the vertical parts 32, 32 of the plurality of anti-slip devices 3 are located closer to the shoe body 1 than the ground contact surface 21B of the outsole 21, push-up can be further suppressed. be able to. Furthermore, when moving on a flat surface, the contact surface 21B of the outsole 21 reliably grips the flat surface, making it difficult to slip. As the shoes are used, as the contact surface 21B of the outsole 21 wears out, the contact tips 32A, 32A of the vertical parts 32, 32 of the anti-slip device 3 gradually move toward the contact surface 21B. As a result, the gripping force of the anti-slip tool 3 can be exerted well. In short, you can make the shoes just right while using them.

In the present invention, the sole main body portion 2 includes 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 second region 6 having no anti-slip devices 3. There is.

Here, as shown in FIGS. 4 and 5, the sole body part 2 has a total length line 9 which is the longest line connecting the toe side edge 7 to the heel side edge 8, a width direction perpendicular to the total length line 9, and a total length. After defining a total inner width 10 from the line 9 to the inner end in the width direction and a total outer width 11 from the full length line 9 to the outer end in the width direction, the first region 5 and the second region 6 are defined. has been identified. Note that FIG. 4 shows two types of bottom body parts 2, 2 having different external shapes.

Specifically, the second region 6 includes a first line 12 extending in the width direction at a position of 89% of the length of the full length line 9 from the heel side end 8 and a length of the full length line 9 from the heel side end 8. A second line 13 extending in the width direction at a position of 68% of the width, and a line extending in the width direction from the full length line 9 to the full inner width 10 at a position of 77% of the length of the full length line 9 from the heel side end 8 of the sole body portion 2. A third line 14 (see FIG. 5) extending parallel to the full length line 9 at a 45% position, and a full length line in the width direction at a position of 77% of the length of the full length line 9 from the heel side end 8 of the sole body 2. 9 and a fourth line 15 (see FIG. 5) extending parallel to the full length line 9 at a position 55% of the total outer width 11 from the full length line 9 in the width direction. The position 68% of the length of the full length line 9 from the heel side end 8 corresponds to the sesamoid bone (ball of the foot) 20 of the foot shown in Fig. 6, and is said to be the part that receives a lot of pressure from the ground surface. ing.

Further, as shown in FIG. 4, the second region 6 includes a fifth line 16 extending in the width direction perpendicular to the full length line 9 at a position of 35% of the length of the full length line 9 from the heel side end 8, and a fifth line 16 extending in the width direction perpendicular to the full length line 9 from the heel side end 8. It further has a second section 62 defined by a sixth line 17 extending in the width direction perpendicular to the full length line 9 at a position of 9% of the length of the full length line 9 from the end 8 .

In contrast to the second region 6, the first region 5 has a third section 51 (see FIG. 4) defined by the second line 13 and the fifth line 16.

Further, as shown in FIG. 4, the first region 5 includes a fourth section 52 between the first line 12 and the toe side end 7, and a fifth section between the heel side end 8 and the sixth line 17. 53. Furthermore, the first region 5 includes a sixth section 54 surrounded by the first line 12, the third line 14, the second line 13, and the inner end in the width direction; It has a seventh section 55 surrounded by the second line 13 and the outer end in the width direction.

As shown in FIG. 6, the first section 61 is an area corresponding to the second proximal phalanx 18 and the third proximal phalanx 19 of the foot, and the second section 62 is an area corresponding to the calcaneus 40 and talus of the foot. 41, and the third section 51 is a region corresponding to the cuneiform bone 42, the navicular bone 43, and the cuboid bone 44.

Moreover, FIG. 6 shows two locations (toe side and heel side) where the weight is applied during the pressure-sensitive test. On the toe side, the first A pressure sensitive area 45 at the center is the area where the most weight is applied and the reaction force from the ground surface acts on the sole of the foot. The second A pressure sensitive area 46 located is the area where the second most weight is applied and the second largest reaction force from the ground surface acts on the sole of the foot, and is located outside the second A pressure sensitive area 46. The 3rd A pressure sensitive area 47 located at The fourth A pressure sensitive area 48 located on the outside is the area where the fourth largest weight is applied and the fourth largest reaction force from the ground surface acts on the sole of the foot. Note that the 5th A pressure sensitive area 49 located outside the 4th A pressure sensitive area 48 is the area where the fifth largest weight is applied and the fifth largest reaction force from the ground surface acts on the sole of the foot. However, since the reaction force that acts is very small, the fifth A pressure sensitive area 49 is negligible. The area covering these four pressure-sensitive areas 45, 46, 47, and 48 (the area where pressure is likely to be applied on the toe side of the sole body part 2) corresponds to the first section 61 of the second area 6, This first section 61 does not have the anti-slip device 3. This eliminates the push-up caused by the anti-slip device 3 in the first section 61, where the wearer's weight acts intensively, and it is possible to suppress push-up when standing up as a whole.

On the other heel side, the 1B pressure sensitive area 70 (area smaller in area than the 1A pressure sensitive area 45) in the center is where the most weight is applied, and the reaction force from the ground surface is applied to the sole of the foot. The second B pressure sensitive area 71, which is the area that acts the most and is located outside of the first B pressure sensitive area 70, has the second highest weight, and the reaction force from the ground on the sole of the foot is the second largest. The third B pressure sensitive area 72 located outside the second B pressure sensitive area 71 is the area where the weight is applied the third and the reaction force from the ground on the sole of the foot is the third largest. The 4th B pressure sensitive area 73 located outside the 3rd B pressure sensitive area 72 is the area where the weight is applied the fourth, and the reaction force from the ground surface on the sole of the foot is the fourth This is the area that acts on the order of magnitude. Note that the 5B pressure sensitive area 74 located outside the 4B pressure sensitive area 73 is the area where the fifth largest weight is applied and the reaction force from the ground surface acts on the sole of the foot with the fifth largest magnitude. However, since the reaction force that acts is very small, the pressure sensitive area 74 of 5B is negligible. The area that covers these four pressure-sensitive areas 70, 71, 72, and 73 (the area where pressure is easily applied on the heel side of the sole body 2) is the second section 62 of the second area 6. The second section 62 does not have the anti-slip device 3. This eliminates the push-up by the anti-slip device 3 in the second section 62 where the wearer's weight acts intensively, and it is possible to suppress push-up as a whole when standing up.

The sole and shoe of the present invention are not limited to the embodiments described above.

In the embodiment, both the first section 61 and the second section 62 do not have the anti-slip device 3, but only the first section 61 may not have the anti-slip device 3.

Further, in the embodiment described above, the anti-slip tool 3 is made of metal, but it may be made of synthetic resin, synthetic rubber, or the like. Moreover, although the anti-slip tool 3 is constructed by bending a bar-shaped member, it can also be constructed from, for example, a rectangular plate-shaped member.

Further, in the embodiment, the grounding tips 32A, 32A of the anti-slip device 3 are positioned closer to the shoe body side than the grounding surface 21B of the sole body 2, but the grounding tips 32A, 32A of the anti-slip device 3 may be located at the same position as the ground plane 21B of the bottom body portion 2.
