Description

Anti-hook shoes with elastic water absorption structure

The present invention relates to an anti-hook shoe, and more particularly to an anti-hook shoe having an elastic water absorbing 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 an elastic absorbent structure that effectively absorbs water droplets from the sole to prevent splashing of 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 an elastic water absorbing structure for carrying a user's weight and contacting with water on a ground, and absorbing water on an outer surface of the sole when the sole is off the ground to prevent water from splashing into the shoe On the surface. .

With the above-mentioned anti-hook shoes, the elastic water-absorbing structure is arranged by the sole, and when the shoes are off the ground, the water is adsorbed by the elastic water-absorbing structure to prevent the water from splashing out, so as to prevent the water droplets from splashing on the upper, even socks, pants, etc. . When the shoe is landing, the water can be drained against the weight of the user.

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 rainy day, 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, if the water brought up by the sole can be firmly absorbed into the sole, there is no chance for the water to splash. The solution adopted in this case is to provide an elastic water-absorbing structure on the sole of the shoe. When the shoe is off the ground, the water is adsorbed by the elastic water-absorbing structure to prevent the water from splashing out. When the shoe is landing, the water can be drained by the weight of the user.

Figure 2 shows a side view of a water snoring shoe in accordance with a first embodiment of the present invention. As shown in FIG. 2, the embodiment provides an anti-hook shoe 1 comprising a sole 10 and an upper 60. The sole 10 is a portion that is in contact with the 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 an elastic water absorbing structure 20 for carrying a user's weight WT and contacting the water W on the ground G, and absorbing on an outer surface 12 of the sole 10 when the sole 10 leaves the ground. Water W to prevent water from splashing onto the upper 60.

In the embodiment, the elastic water absorbing structure 20 is a cotton body. The cotton body hardens when dry, providing the user with the ability to walk on a dry floor. The cotton body gradually absorbs moisture and softens when it encounters water, but still provides the user with the function of walking on a dry ground. In one example, the thickness/height of the cotton body is between about 2 and 6 mm. In another example, the thickness/height of the cotton body is between about 3 and 5 mm. In yet another example, the thickness/height of the cotton body is between about 3.5 and 4.5 mm. In yet another example, the cotton body The thickness/height is approximately 3.9 mm.

Fig. 3 is a partially enlarged cross-sectional view showing the anti-hook shoe according to the second embodiment of the present invention. As shown in FIG. 3, the elastic water absorbing structure 20 of the anti-hook shoe 1 of the present embodiment comprises a base 21, an outer cover 22 and a sponge 23. The outer cover 22 is for direct contact with water W on the ground G. The sponge 23 is disposed in a space 27 formed by the substrate 21 and the outer cladding 22. The outer cover 22 has a plurality of suction holes 24 that communicate with the holes 25 of the sponge body 23. In the present embodiment, the diameter of the water absorbing holes 24 is between 2 and 4 mm, preferably between 2.5 and 3.5 mm, and more preferably about 3 mm. The distribution density of the water absorbing holes 24 is approximately 0.8 to 0.4 (pieces per square centimeter), preferably 0.7 to 0.5 (pieces per square centimeter), and more preferably 0.65 to 0.55 (pieces per square centimeter). It is preferably 0.57 (pieces per square centimeter).

It should be noted that the elastic water absorbing structure 20 may further include a spacer layer 26. The spacer layer 26 is connected to the substrate 21 and the outer cladding layer 22. The sponge 23 is disposed in the space 27 formed by the substrate 21, the spacer layer 26, and the outer cladding 22. In this way, the plurality of spaces 27 can be managed in a partition, or the function of one space 27 can be lost without affecting the water absorbing and splash-proof function of other spaces.

Figure 4 is a bottom plan view of the anti-hook shoe according to the third embodiment of the present invention. 5 and 6 are partially enlarged cross-sectional views showing two states of the anti-hook shoe according to the third embodiment of the present invention. As shown in FIG. 4 to FIG. 6 , the elastic water absorbing structure 20 of the present embodiment includes a plurality of channels 28 and a plurality of suction chambers 29 respectively connected to the channels 28 , and the channels 28 and the water absorbing chambers 29 are deformable. To absorb and drain water. The passage 28 of the elastic water absorbing structure 20 and the suction cavity 29 are formed in the base 21, and the base 21 has the ability to be elastically deformed. In FIG. 5, the substrate 21 is pressed by the weight WT, and the water W is discharged from the suction chamber 29 through the passage 28 to between the ground G and the outer surface 12. In Fig. 6, the user lifts the shoe, and the base 21 is no longer compressed and deformed, so that the suction chamber 29 and the passage 28 become large, and water is sucked therein. Accordingly, the elastic absorbent structure 20 adsorbs water from the outer surface 12 of the sole 10 when the sole 10 leaves the water surface such that there is no continuous water film in the outer surface 12 of the sole 10 (in the two suction chambers 29 of FIG. 6) The water has been separated). As a result, the dispersed water adsorbed in the passage 28 and the suction chamber 29 cannot be splashed forward or backward along the outer surface 12 to the upper.

In FIG. 4, the suction chambers 29 include a plurality of spherical cavity 29C and a plurality of elliptical cavities 29E. In the other, each of the suction chambers 29 is an elliptical cavity 29E. In still another example, each of the suction chambers 29 is a spherical cavity 29C. In the design of an elliptical cavity 29E, the bottom area of the sole taken generally about 20,000mm ^2, assuming that the thickness of the water film is 2mm, then the volume of the water film to 20,000mm ^3. The volume of an elliptical cavity 29E is 4 π abc/3, and the design data is a = 15 mm, b = 15 mm, and c = 3 mm. Assuming that the elliptical cavity 29E has only 2/3 of the volume of inhaled water, the total absorbed water volume is 600 π, and if 3/4 of the total volume of the water film is inhaled by the elliptical cavity 29E, splashing of the upper can be prevented. According to the above conditions, it can be calculated that the number of the elliptical cavities 29E is at least (40000*3/4) / (600 π) ≒ 16. However, the above is only an example of derivation and is not intended to limit the invention thereto. In still another example, the arrangement density of the elliptical cavity 29E at the intermediate portion is lower than the arrangement density of the front and rear portions, and the arrangement density of the front portion is higher than the arrangement density of the rear portion. In normal cases, the pressure on the soles of the feet will be concentrated in the front and back, because there is a bow in the middle of the sole. When you move forward to lift your foot, the pressure will concentrate on the forefoot, so that the cavity will be squeezed more completely and will achieve better water absorption in the future.

It should be noted that other texture structures may be formed on the outer surface 12 to increase friction or provide drainage. The water absorbing cavity 29 and the channel 28 can be formed on the peaks and/or valleys of the grain structure to provide functions of water absorption and water retention, thereby achieving the effect of preventing splashing.

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 second embodiment, indicating that relatively more moisture is absorbed. What is to be expressed in Table 1 is that the use of the present invention can effectively prevent the disadvantages of water splashing the upper.

According to the above embodiment of the present invention, the elastic water absorbing structure is provided by the sole, and when the shoe is off the ground, the water is adsorbed by the elastic water absorbing structure to prevent the water from splashing out, so as to prevent the water from splashing on the upper, even the socks, the pants, and the like. . When the shoe is landing, the water can be drained against the weight of the user.
