Description

Technical Field

[0001] This utility model belongs to the field of shoe sole technology, specifically relating to a shoe sole that can freely switch between drainage and water collection. Background Technology

[0002] In recent years, with the increasing demand for functional footwear from various industries and the military, especially for working in environments with alternating water and land conditions, ensuring that there is no water accumulation in the shoe cavity is particularly important. Currently, most shoes and boots on the market only have a single function of waterproofing or drainage. If water enters the shoe through the opening of waterproof shoes and boots, it is difficult for the water to drain out of the shoe cavity. While drainage shoes and boots drain water, water can also enter the shoe cavity through the drainage holes, which cannot fully solve the problem of water accumulation in the shoe cavity.

[0003] Patent application number 201821783947.4 discloses a circulating drainage shoe outsole, specifically comprising an inner outsole and an outer outsole. The outer edge of the outer outsole extends upwards, and at least one pair of drainage holes are symmetrically arranged on both sides of the outer edge. The upper surface of the inner outsole has drainage grooves, including transverse drainage grooves and circulating drainage grooves. The upper surface of the inner outsole has at least one transverse drainage groove, the two ends of which are connected to the drainage holes on both sides of the outer outsole. The circulating drainage grooves include circumferential circulating drainage grooves, longitudinal circulating drainage grooves, and transverse circulating drainage grooves. Multiple drainage holes on both sides of the outsole drain excess water from the drainage grooves. In this patent, the two ends of the transverse drainage groove are connected to the drainage holes on both sides of the outer outsole, allowing water inside the shoe cavity to drain through the drainage grooves and drainage holes. However, external water can also enter the shoe cavity through the drainage holes, thus failing to fully achieve the drainage function and lacking waterproof performance.

[0004] Therefore, the technical problem to be solved by this utility model is that existing shoes and boots only have a single function of waterproofing or drainage. Utility Model Content

[0005] To address the technical problem that existing footwear only has a single function of waterproofing or drainage, this invention provides a sole that can freely switch between drainage and water retention.

[0006] The specific plan is as follows:

[0007] A shoe sole that can freely switch between drainage and water retention includes an outsole and a midsole above the outsole. The two sides of the outsole extend upwards, and a drainage valve is provided on the edge of the outsole. A drainage channel is provided on the upper surface of the midsole, and the drainage channel is connected to a drainage trough. The bottom of the drainage channel is lower than the upper surface of the midsole and higher than the bottom of the drainage trough. The drainage trough and the drainage valve are positioned correspondingly, and the drainage trough is connected to the outside through the drainage valve.

[0008] The drain valve includes a base with a protrusion and a hole. The hole corresponds to the position of the drain groove. A vertical groove is provided on one side of the hole. A push rod is slidably connected in the groove. A baffle is provided at the end of the push rod that cooperates with the groove. The outer periphery of the baffle fits against the inner wall of the protrusion and has the same curvature. The push rod slides up and down in the groove, which drives the movement of the baffle and controls the opening or closing of the hole.

[0009] The baffle is an arc-shaped piece or a cylinder with a water passage. When the water passage corresponds to the hole, it can communicate with the drainage groove. When the baffle is an arc-shaped piece, the outer periphery of the baffle fits against the inner wall of the protrusion and has the same curvature. The size of the baffle is larger than the size of the hole. The push rod slides up and down in the groove, causing the baffle to move up and down, controlling the opening or closing of the hole. When the baffle is a cylinder with a water passage, the outer periphery of the baffle fits against the inner wall of the protrusion and has the same curvature. The push rod slides up and down in the groove, causing the baffle to rotate, controlling the opening or closing of the hole.

[0010] The upper and lower ends of the groove have the same width, and the width narrows towards the middle.

[0011] A drainage groove is provided on one side of the midsole at the heel position, and a drainage valve is provided on the side edge of the outsole at the heel position, with the drainage groove and the drainage valve corresponding to each other.

[0012] The drainage channels include horizontal drainage channels, vertical drainage channels and circumferential drainage channels. The horizontal drainage channels, vertical drainage channels and circumferential drainage channels are interconnected and do not penetrate the bottom of the middle bottom. The horizontal drainage channels are connected to the drainage trough.

[0013] The lateral drainage channels are located at the ball of the foot and heel, and are spaced apart in the width direction of the ball of the foot and the width direction of the heel. The vertical drainage channels extend from the toe to the heel along the length of the foot and are located at the center of the foot. The circumferential drainage channels surround the edge of the upper surface of the midsole.

[0014] The outsole is made of rubber and has anti-slip texture on the bottom, while the midsole is made of high-elastic foam material.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention provides a shoe sole that can freely switch between drainage and water collection. The upper surface of the midsole is provided with multiple drainage channels, which eventually converge into a drainage trough. A drainage valve is provided on the outsole at the position corresponding to the drainage trough. The drainage trough is connected to the outside through the drainage valve. Water inside the shoe cavity is collected into the drainage trough through the drainage channels and discharged through the drainage valve. The opening and closing of the hole can be controlled by the drainage valve, so that the shoe has both waterproof and drainage functions at the same time, and can be freely switched, making it convenient to use.

[0023] Slide 36 Detailed Implementation

[0024] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the implementation of this utility model, not all of it. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] like Figure 1-3 As shown, this utility model provides a shoe sole that can freely switch between drainage and water collection, including an outsole 1 and a midsole 2 above the outsole 1. The two sides of the outsole 1 extend upwards, and a drainage valve 3 is provided on the edge of the outsole 1. A drainage channel 21 is provided on the upper surface of the midsole 2. The drainage channel 21 is connected to a drainage groove 22. The bottom of the drainage channel 21 is lower than the upper surface of the midsole 2 and higher than the bottom of the drainage groove 22. The drainage groove 22 corresponds to the position of the drainage valve 3, and the drainage groove 22 is connected to the outside through the drainage valve 3.

[0026] This invention provides a shoe sole that can freely switch between drainage and water collection. The upper surface of the midsole is provided with multiple drainage channels, which eventually converge into a drainage trough. A drainage valve is provided on the outsole at the position corresponding to the drainage trough. The drainage trough is connected to the outside through the drainage valve. Water inside the shoe cavity is collected into the drainage trough through the drainage channels and discharged through the drainage valve. The opening and closing of the hole can be controlled by the drainage valve, so that the shoe has both waterproof and drainage functions at the same time, and can be freely switched, making it convenient to use.

[0027] like Figure 4 and Figure 5 As shown, the drain valve 3 includes a base 31 with a protrusion 32 on it. A hole 33 is formed on the protrusion 32, corresponding to the position of the drain channel 22. A vertical groove 36 is provided on one side of the hole 33, and a push rod 34 is slidably connected within the groove 36. A baffle 35 is provided at the end of the push rod 34 that engages with the groove 36. The outer periphery of the baffle 35 fits against the inner wall of the protrusion 32 with the same curvature. The push rod 34 slides up and down within the groove 36, causing the baffle 35 to move and controlling the opening or closing of the hole 33. Since the hole 33 corresponds to the position of the drain channel 22, which connects to the drain channel 21, opening the hole 33 allows water to drain from inside the shoe, while closing the hole 33 enables the shoe to remain waterproof.

[0028] like Figure 4 and Figure 5 As shown, the baffle 35 is an arc-shaped piece or a cylinder with a water passage. When the water passage corresponds to the hole 33, it can communicate with the drainage groove 22. When the baffle 35 is an arc-shaped piece, the outer periphery of the baffle 35 fits against the inner wall of the protrusion 32 and has the same curvature. The size of the baffle 35 is larger than the size of the hole 33. The push rod 34 slides up and down in the slide groove 36, driving the baffle 35 to move up and down, controlling the opening or closing of the hole 33. When the baffle 35 is a cylinder with a water passage, the outer periphery of the baffle 35 fits against the inner wall of the protrusion 32 and has the same curvature. The push rod 34 slides up and down in the slide groove 36, driving the baffle 35 to rotate, controlling the opening or closing of the hole 33.

[0029] Specifically, when the baffle 35 is an arc-shaped piece, such as Figure 4 a and Figure 4As shown in Figure b, the outer periphery of the baffle 35 fits against the inner wall of the protrusion 32. When the push rod 34 slides up and down in the groove 36, the baffle 35 slides up and down against the inner wall of the protrusion 32. The size of the baffle 35 is set larger than the size of the hole 33 to ensure that the baffle 35 can cover the hole 33. When the push rod 34 is at the upper end of the groove 36, the baffle 35 covers the hole 33, and the hole 33 is in a closed state, realizing the waterproof function of the shoe. When the push rod 34 slides along the groove 36 to the lower end of the groove 36, the baffle 35 falls down until the hole 33 is completely exposed. At this time, the hole 33 is connected to the drainage groove 22, realizing the drainage function of the shoe. It should be noted that there is a gap between the inner wall of the protrusion 32 and the drainage groove 22. The bottom end of the baffle 5 can rotate and fall into the drainage groove 22, so that there is enough rotation space for the baffle 5. Figure 4 The positional relationship between the drain valve 3 and the middle bottom 2 in b is shown.

[0030] When the baffle 35 is a cylinder with a water passage 351, such as Figure 5 a and Figure 5 As shown in b, the outer periphery of the baffle 35 fits against the inner wall of the protrusion 32. When the push rod 34 slides up and down in the groove 36, the baffle 35 rotates against the inner wall of the protrusion 32. When the push rod 34 is at the upper end of the groove 36, the solid part of the baffle 35 blocks the hole 33. At this time, the hole 33 is in a closed state, realizing the waterproof function of the shoe. When the push rod 34 slides along the groove 36 to the lower end of the groove 36, the baffle 35 rotates until the water passage 351 corresponds to the hole 33. At this time, the hole 33 is connected to the drainage groove 22 through the water passage 351, realizing the drainage function of the shoe.

[0031] In this embodiment, a groove 36 is provided at the middle position of the protrusion 32, and a hole 33 is provided on each side of the groove 36. Both holes 33 can communicate with the drainage groove 22. The two holes 33 are provided to speed up the drainage.

[0032] like Figure 4 As shown in Figure a, the upper and lower ends of the slide groove 36 have the same width, and the width narrows towards the middle. The advantage of this design is that when the push rod 34 is at the upper end of the slide groove 36, the push rod 34 can be prevented from falling down naturally because the slide groove 36 is wide at both ends and narrow in the middle.

[0033] like Figure 1 and Figure 2As shown, a drainage groove 22 is provided at the heel position on one side of the midsole 2, and a drainage valve 3 is provided at the heel position on the side edge of the outsole 1. The drainage groove 22 and the drainage valve 3 are positioned correspondingly, so that water in the drainage groove 22 can be directly discharged through the drainage valve 3. In this embodiment, the drainage groove 22 is located at the heel position on the outer side of the midsole 2, and the drainage valve 3 is located at the heel position on the outer side of the outsole 1. The drainage groove 22 and the drainage valve 3 are positioned correspondingly, so that the drainage groove 22 can communicate with the outside through the drainage valve 3.

[0034] like Figure 1 As shown, the drainage channel 21 includes a horizontal drainage channel 211, a vertical drainage channel 212, and a circumferential drainage channel 213. The horizontal drainage channel 211, the vertical drainage channel 212, and the circumferential drainage channel 213 are interconnected and do not penetrate the bottom of the middle bottom 2. The horizontal drainage channel 211 is connected to the drainage trough 22.

[0035] The lateral drainage channel 211 is provided at the ball of the foot and the heel, and is spaced apart in the width direction of the ball of the foot and the width direction of the heel. The vertical drainage channel 212 extends from the toe to the heel along the length direction of the foot and is located at the center of the foot. The circumferential drainage channel 213 surrounds the edge of the upper surface of the midsole 2.

[0036] Multiple drainage channels 21 are provided and interconnected, covering the entire upper surface of the midsole 2, increasing the contact area with water, so that water can flow freely in the drainage channels 21, facilitating water drainage. In this embodiment, the edge of the midsole 2 is glued to the outsole 1, and only a low-lying drainage groove 22 is reserved as the water outlet, so that the water accumulated inside the shoe can be discharged through the drainage channels 21 and finally converge into the drainage groove 22 and discharged through the drainage hole 12.

[0037] The outsole 1 is made of rubber and has anti-slip texture on the bottom. The midsole 2 is made of high-elastic foam material. The high-elastic foam midsole is on the upper layer of the sole and has shock absorption and rebound effect. The rubber outsole is on the lower layer of the sole and has wear resistance and anti-slip effect.

[0038] The specific working process of this utility model is as follows:

[0039] In use, a drainage valve 3 is installed on the side of the outsole 1, and the base 1 of the drainage valve 3 is hidden inside the sole, with only the part inside the edge of the protrusion 32 exposed. The movement of the push rod 34 in the groove 36 drives the movement of the baffle 35, which either covers or exposes the hole 33, thereby switching between the waterproof and drainage functions of the shoe. Specifically...

[0040] When the baffle 35 is an arc-shaped piece, push the push rod 34 upward along the slide groove 36. The push rod 34 drives the baffle 35 to move upward until the push rod 34 moves to the upper end of the slide groove 36. At this time, the baffle 35 completely covers the hole 33, and the hole 33 is in the closed state, realizing the waterproof function of the shoe. Push the push rod 34 downward along the slide groove 36. The push rod 34 drives the baffle 35 downward until the push rod 34 moves to the lower end of the slide groove 36. At this time, the hole 33 is completely exposed and is in the open state. Water in the drainage groove 22 is discharged through the hole 33, realizing the drainage function of the shoe.

[0041] When the baffle 35 is cylindrical, push the push rod 34 upward along the slide groove 36. The push rod 34 drives the baffle 35 to rotate until the push rod 34 moves to the upper end of the slide groove 36. At this time, the baffle 35 completely blocks the hole 33, and the hole 33 is in a closed state, realizing the waterproof function of the shoe. Push the push rod 34 downward along the slide groove 36. The push rod 34 drives the baffle 35 to rotate until the push rod 34 moves to the lower end of the slide groove 36. At this time, the water passage 351 of the baffle 35 is connected to the hole 33. The water in the drainage groove 22 is discharged from the hole 33 through the water passage 351, realizing the drainage function of the shoe.

[0042] If water enters the shoe from the shoe opening, the water inside the shoe will be collected in the drainage groove 22 on the lower surface through the drainage channel 21 set on the upper surface of the midsole 2, and discharged through the drainage valve 3 on the outsole 1, which can realize the rapid drainage of water inside the shoe. Since the hole 33 corresponds to the position of the drainage groove 22, the bottom of the drainage groove 22 is lower than the bottom of the drainage channel 21. During the drainage process, external water will not enter the shoe.

[0043] The shoes of this invention are suitable for working in environments with alternating water and land conditions. They can freely switch between drainage and waterproof functions. When working or training in water, the drainage valve 3 on the side of the outsole can be opened. Water can be quickly drained through the drainage channel 21, drainage groove 22, and drainage hole 12 after entering the shoe cavity. When training on land, closing the drainage valve 3 can prevent water from entering the shoe cavity through the sole, ensuring that there is no water accumulation in the shoe cavity and improving comfort.

[0044] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
