Description

Anti-hook shoes with stepped stop structure

The present invention relates to an anti-hook shoe, and more particularly to an anti-hook shoe having a stepped stop structure to prevent water from hooking onto the upper.

When a user walks or runs on a rainy or wet ground wearing shoes, it is usually getting wet and wet, giving the user a bad feeling.

Figure 1 shows a schematic view of a splash of water in a conventional shoe 100 walking on a wet ground G. As shown in Fig. 1, there is water W on the ground G, the water W is taken up by the sole 110 of the shoe 100, and there is adhesion FA between the water W and the sole 110, horizontal centrifugal force FH and vertical centrifugal force FV, in these three forces Under effect, the generated water droplet D1 splashes over the upper 160 and finally falls on the upper 160, while splashing the upper 160, as the water droplet D2 splashes forward and does not splash onto the upper 160.

Leather shoes, sports shoes, casual shoes, etc., which are currently manufactured by shoe manufacturers, mainly consider the design of ventilation. The problem that the upper will be splashed when it is raining or walking on wet ground is not particularly treated. Although it can improve the waterproof material of the upper, it will affect the breathability. Therefore, under the dual consideration of both ventilation and splash prevention, it is impossible to manufacture a satisfactory footwear product.

Accordingly, it is an object of the present invention to provide an anti-hook shoe having a stepped stop structure that effectively blocks water droplets from the sole strap from splashing the upper.

To achieve the above object, the present invention provides an anti-hook shoe comprising a sole and an upper. The upper is attached to the sole and is located above the sole. The sole has a load bearing structure and a differential stop structure. The load bearing structure is used to carry the weight of a user and is in contact with water on a ground. The stop structure is used to stop the water droplets carried by the load-bearing structure from splashing toward the upper.

With the above-mentioned anti-hook shoes, the step-type blocking structure can effectively block the water droplets intended to splash above the upper to prevent the water droplets from splashing on the upper, even socks, pants and the like. Whether it is to use the method of separating water droplets to match the upper surface of the water droplets, or to use the water receiving layer to match the vertical surface of the water droplets, it is possible to prevent the water droplets from splashing upwards and to ensure that the user's upper is not splashed.

In order to make the above description of the present invention more comprehensible, the preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

The anti-hooking shoe of the present invention is an improved design for the texture of the sole. The invention is based on a motion pattern of water droplets found in a state in which the user walks on a wet ground, and an improved design is proposed through mechanical analysis. The water droplets have adhesion and centrifugal force on the sole of the movement, and the centrifugal force is decomposed into components in the vertical direction and the horizontal direction. The amount of centrifugal force in the vertical direction will cause the water droplets to lick above the upper, thus splashing the upper.

Therefore, the present solution adopts two schemes. The first scheme is to make a step on the leading edge of the sole, so that the vertical movement of the water droplets brought by the sole is blocked by the leading edge, and the water droplet is prevented from splashing upward to the upper. The second solution is to make a recess in the front edge portion of the sole so that the leading edge of the recess provides a retaining wall to prevent water droplets from splashing onto the upper. None of the above two solutions will make the wearer of the shoe feel different from the usual habits.

Figure 2 shows a side view of the anti-hook shoe 1 in accordance with a first embodiment of the present invention. Fig. 3 is a side elevational view, partly in elevation, of the anti-hook shoe 1 according to the first embodiment of the present invention. As shown in FIG. 2 and FIG. 3, the anti-hook shoe 1 of the present embodiment includes a sole 10 and an upper 60. The sole 10 is a portion that is in contact with a ground G, and the upper 60 is a portion that covers the foot of the user. The upper 60 is coupled to the sole 10 and is positioned above the sole 10 (as viewed in normal normal use).

The sole 10 has a load bearing structure 20 and a differential stop structure 30. The load bearing structure 20 is used to carry the weight of a user and is in contact with the water W on the ground G. The stop structure 30 serves to stop the water droplets carried by the load-bearing structure 20 from splashing toward the upper 60. Parallel block The stopping structure 30 provides a protruding step portion 31, which can be separated into the water droplet D1 by the step portion 31 when the water brought up by the sole is pushed forward, so that the water droplet D1 can be blocked under the sole 10 without Splashing over the upper 60. As for the other water droplets D2 will splash forward and will not splash above the upper. Therefore, the design of the sole is to block the water droplets splashing back and forth.

The stop structure 30 is located in a front portion 11 of the sole 10 to prevent the sole 10 Splash of water caused by lifting forward. The stop structure 30 is also located in a rear portion 12 of the sole 10 to prevent splashing of water caused by the sole 10 being lifted rearward.

The stopper structure 30 includes the aforementioned step portion 31, and the step portion 31 makes the sole 10 The front portion 11 does not contact the ground G when the load-bearing structure 20 is in flat contact with the ground G. The stop structure 30 also includes another step 31 that causes the rear portion 12 of the sole 10 to not contact the ground G when the load bearing structure 20 is in flat contact with the ground. The step portion 31 has a height difference of between 2 and 6 mm, in particular a height difference of between 3 and 5 mm, which accounts for 65% to 85% of the total thickness of the sole, more particularly a height difference of 3.5 to 4.5 mm. , accounting for 70% to 80% of the total thickness of the sole. In one example, the sole 10 has a total thickness of 5.2 mm and a height difference of 3.9 mm, which accounts for 75% of the total thickness of the sole, and is applicable to the second and third embodiments. In another example, the step portion 31 has a height difference of between 6 and 9 mm, in particular a height difference of between 7 and 8 mm, which accounts for 70% to 80% of the total thickness of the sole, more particularly 7.2. The height difference to 7.8 mm accounts for 72% to 78% of the total thickness of the sole. In yet another example, the sole 10 has a total thickness of 10 mm and a height difference of 7.5 mm, which accounts for 75% of the total thickness of the sole, and is applicable to the second and third embodiments. The experimental data of Table 1 below in this case is based on a height difference of 3.9 mm, and the experimental data of Table 2 is based on a height difference of 7 mm.

In another aspect, the sole 10 includes a first portion 20 and a second portion. Part 30. A step portion 31 is formed between the first portion 20 and the second portion 30. The first portion 20 and the second portion 30 may be integrally formed or may be bonded together by an adhesive. in In Fig. 3, the angle θ is 90 degrees. However, in other examples, the angle θ may be less than or greater than 90 degrees.

4 to 7 show the number of anti-hook shoes according to the first embodiment of the present invention. A bottom view of an example. As shown in FIG. 4, from the bottom view of the sole 10, in a state where the front portion 11 is upward, the step portion 31 has a substantially M shape to reduce the concentration of water droplets in the center of the front portion 11 of the sole 10. In one example, the distance P1 from the leading edge of the front portion 11 is about 70 to 50 mm, preferably 65 to 55 mm, and more preferably 58 to 62 mm; the point P2 is from the foremost edge of the front portion 11. The distance is approximately 23 to 3 mm, preferably 18 to 8 mm, and more preferably 15 to 11 mm; and the distance of the point P3 from the foremost edge of the front portion 11 is approximately 28.5 to 8.5 mm, preferably 23.5 to 13.5 mm, and preferably between 20 and 17 mm. In another example, the distance of the point P2 from the foremost edge of the front portion 11 is between about 8% and 4% of the total length of the sole, preferably between 7% and 5%.

In addition, from the bottom view of the sole 10, the rear portion 12 is upwardly shaped In this case, the step portion 31 has a substantially M shape to reduce the concentration of water droplets in the center of the portion 12 behind the sole 10. It is worth noting that the approximate M shape can also be smoothed. As shown in FIG. 5, the step portion 31 has a linear shape. As shown in FIG. 6, the step portion 31 has a concave curved shape. As shown in FIG. 7, the step portion 31 has a convex curved shape. It should be noted that the lower surface of the load-bearing structure 20 and the step-type stop structure 30 may also form other lines to increase the friction or provide a drainage design. The load bearing structure 20 also has the ability to be elastically deformed to provide cushioning. In one example, the elasticity of the load bearing structure 20 and the height difference of the step portion 31 are designed such that the stepped stop structure 30 does not come into contact with water when the load bearing structure 20 is in contact with water. This step 31 differs from the design of the sole that is gradually tilted up in a continuous curve because the latter cannot divide the water droplets and block the sole. In the present embodiment, the leading edge portion of the step portion 31 to the front portion 11 and the trailing edge portion of the step portion 31 to the rear portion 12 do not have any structure or texture. It is flush with the load-bearing structure 20, and there is no structure or texture to contact the ground or the ground.

As shown in Figures 9A and 9B, the stop structure 30 includes a recess 36 having an inclined surface 37 and a vertical stop surface 38. The vertical stop surface 38 is located in the front portion 11 of the sole 10, and the inclined surface 37 is oriented to the vertical stop surface. 38 is inclined in a direction away from the ground G. That is, the stopper structure 30 includes an inclined groove 30B and a non-inclined groove 30A, and the non-inclined groove 30A is adjacent to the front portion 11. The total length of the inclined groove 30B and the non-inclined groove 30A in the direction of the line 9B-9B is preferably between 25 and 45 mm, more preferably between 40 and 30 mm, or about 35 mm, or in other examples. It accounts for between 15% and 5% of the total length of the anti-hook shoes (parallel to the direction of line BB), especially between 10% and 11%, in order to provide better water storage and water retention while maintaining The basic function of the shoes. In still another example, the lengths of the inclined grooves 30B and the non-inclined grooves 30A in the direction of the lines 9B-9B are about 14 mm ± 3 mm and 4 mm ± 1 mm, respectively. The recess 36 can have a horizontal plane 39 that connects the inclined surface 37 and the vertical stop surface 38. The horizontal plane 39 makes the non-inclined tank 30A have a larger water content and is suitable for adsorbing more water. It should be noted that the horizontal plane 39 does not have to exist. In other examples, the inclined surface 37 and the vertical stop surface 38 may be directly connected. Moreover, in the design adjacent to the rear portion 12, the stop structure 30 includes a recess 36 having an inclined surface 37 and a vertical stop surface 38, the vertical stop surface 38 being located behind the sole 10, and the inclined surface 37 being vertical The stop face 38 is inclined in a direction away from the ground. In one example, the slope of the inclined surface 37 (vertical displacement component / horizontal displacement component) is between 0.7 and 0.3, and the length L is between 10 mm and 6 mm. In another example, the slope of the inclined surface 37 is 0.53 (about equal to 3.9 mm / 7.4 mm) or 0.54 (about equal to 7.5 mm / 14 mm), and the length L is between 9 mm and 7 mm, especially 8 mm. The length L can be as short as possible, but a vertical stop 38 is still required to achieve the function of retaining water. In the present embodiment, in the inclined groove 30B and the non-inclined groove 30A, no structure or texture is flush with the load-bearing structure 20, and no structure or texture is in contact with the ground or the ground, and the entire non-inclined groove 30A is outside. The edge wall surface presents a continuous wall surface for the effect of storage and stop.

9C shows another anti-hooking shoe according to a third embodiment of the present invention. A cross-sectional view of the example. This example differs from Figure 9B in that the pocket 36 does not have an inclined surface 37 and the entire pocket 36 is generally a semi-circular non-inclined groove in which the water content is higher. It should be noted that the stepped stop structures 30 of the front portion 11 and the rear portion 12 described above do not have to exist at the same time, and do not have to have the same type, because any combination can achieve the function of splash prevention.

It is worth noting that the stop 38 does not have to assume a vertical state. Figure 9D Up to 9F is a cross-sectional view showing another example of the anti-hook shoe according to the third embodiment of the present invention. As shown in Fig. 9D, the present example is similar to Fig. 9B except that the stop face is a slanted face 38' which is inclined upwardly and rearward. As shown in Fig. 9E, the present example is similar to Fig. 9B except that the stop face is a slanted face 38' and the slanted face 38' is inclined upwardly. As shown in Fig. 9F, this example is similar to Fig. 9B except that there is no non-inclined groove 30A, that is, the inclined surface 37 is directly connected to the inclined stop surface 38'. These examples all achieve a splash-proof function.

In the second and third embodiments, the stepped stop structure 30 provides The inclined groove/non-inclined groove for absorbing water is used to accommodate water. When the sole is lifted up, the water in the groove is intended to splash forward, but is blocked by the vertical stop surface 38, so that the water cannot be moved. Go on the splash.

In order to prove the effect of the stepped stop structure, the inventor of the case The measurement is performed by attaching a sponge body 300 on the upper (see FIG. 2), performing the same walking mode on the wet ground, and finally measuring the increased weight of the sponge 300. The results are shown in Table 1. . As can be seen from Table 1, the conventional technique is relatively wet compared to the first embodiment and the third embodiment, indicating that relatively more moisture is absorbed. As for the average weight increase of the first embodiment and the third embodiment, which is a negative value, it is simply a measurement error of the electronic scale. What is expressed in Table 1 is that the method of the present invention can effectively prevent the disadvantage that water splashes the upper. Table 2 is another set of experimental data. The experimental method is similar to Table 1, but the shoes worn by the feet are used for experiments, and the invention is also shown to effectively prevent water from splashing the upper.
