Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figures 1 to 3, the shoe waterproofing device 1 according to an embodiment of the present invention, the waterproof portion 2, the cover 4, the removable portion 6 and the close support band portion (5) Include.

The waterproof part 2 includes an adhesive part 20 and an elastic body 3 which are in close contact with the sole of the shoe (hereinafter, referred to as 'shoes'). Here, the waterproof part is a soft PVC material is used because it is to be in close contact with the sole of the hiking boots to perform a sealing function.

The close contact portion 20 further includes a close contact piece 21 disposed at the front and a fixing band 22 disposed at the rear of the sole.

The close contact piece 21 has a substantially rectangular cross section, and is formed in a shape capable of wrapping the periphery of the hiking boots, and the joining wings 211 so that the cover 4 is adhered to the upper end using thermocompression bonding, high frequency bonding, or an adhesive. Is formed. In order to increase the sealing performance between the close contact portion 20 and the sole circumference of the hiking boots, three packings 212 having a soft material and a thin thickness and pointed ends are closely adhered to the inner side of the close contact portion 20. It is formed in the longitudinal direction of the portion 20. Here, the close contact portion 20 is formed by the above-mentioned joining blade 211 extends to the end of the close contact portion 20 so that the fixing band 22 is bonded to the close contact portion 20. At this time, the close contact portion 20 is formed to be in close contact with the sole circumference from the sole of the hiking boots except the heel portion, that is, the concave portion based on the bottom of the sole. In addition, the contact portion is formed so as to surround the outer periphery of the sole at a position slightly higher than the sole of the hiking shoe sole.

Here, the contact portion 20 may be formed with a protective portion 23 protruding a portion of the front upper end of the contact piece 21 to cover the toe cap of the hiking boots. The protective part 23 is thick and the lower portion and the front portion going to the upper side is thinner, the bonding blade 231 is formed on the upper end of the protective portion 23. That is, the bonding blades 211 of the adhesion piece 21 and the bonding wings 231 formed at the upper end of the protection part 23 are connected to each other, and the adhesion piece 21 and the protection part 23 are integrally formed. This is because, when walking, the toe cap portion of the hiking boots hits a tree or a rock, and the cover 4 may be torn, so that the protection portion 23 is formed in front of the close contact piece 21 to protect it. The front of the protective part 23 is formed thick so that it can be prepared. In addition, the protection unit 23 can maintain the attached state without slipping only if the contact area with the toe cap portion of the hiking boots is a predetermined level or more. Accordingly, the cover 4 can be prevented from being damaged even when hitting a tree or a rock while walking, and a shock is transmitted to the hiking boots and the foot by first buffering the impact when the bump is hit by the protective part 23. By preventing this, hiking boots and feet can be protected.

Here, the joint 7 such as a double-sided tape for detaching and attaching the protective part 23 and the hiking boots to the inner surface of the protective part 23 so as to prevent the waterproof part 2 and the cover 4 from peeling off to the top of the hiking boots. ) (Hereinafter referred to as 'double-sided tape') may be installed. For example, when the pedestrian passes by, the waterproof part 2 may be caught by stepping on an obstacle, or the waterproof part 2 may be directly caught by the obstacle, at which time the waterproof part 2 may be separated from hiking boots. Therefore, it is preferable to provide the double-sided tape 7 which attaches and detaches the protection part 23 and hiking boots to the inner surface of the protection part 23. Accordingly, even if the waterproof part 2 is caught by an obstacle, the protection part 23 and the hiking boots are fixed by the double-sided tape 7, thereby preventing the waterproof part 2 and the protection part 23 from being separated from the hiking boots. . Bonding portion formed on the inner surface of the protective portion in addition to the double-sided tape (7) may be applied to the bonding portion 7 of various forms such as Velcro.

The fixing band 22 is divided into two parts in order to easily detach the contact portion 20 from the sole of hiking boots, and each fixing band 22 is joined to the end of the contact portion 20. In addition, the fixing band 22 is formed in the longitudinal direction of the fixing band 22, the bonding blades 221 on the upper end so that the cover 4 is bonded to the fixing band 22. At this time, a portion of the bonding blade 221 is formed at one end of the fixing band 22 so that the fixing band 22 corresponds to the portion extending from the bonding blade 211 of the adhesion piece 21 in order to bond with the adhesion piece 21. Is removed and formed. In addition, the fixing band 22 is formed to be flat in the inner side, the two fixing bands 22 are formed long so that the detachable portion 6 is installed at the other end of the fixing band 22 in order to attach and detach from each other. A description thereof will be described later.

The above-mentioned fixing band 22 is used a soft rubber material having better elasticity than the contact piece 21, the contact piece 21 and the protective portion 23 is harder than the fixing band 22, but can be bent while maintaining the shape. It is formed of a plastic material. This is because the close contact piece 21 and the protective portion 23 is located in front of the fixed band 22, the front portion of the back of the hiking during the walking often collides with the close piece 21 and the protective portion 23 It is preferable that a curved but hard material is used, and the fixing band 22 pulls the contact piece 21 to prevent the contact piece 21 and the fixing band 22 from detaching from the sole. To restrain tightly. At this time, the close contact piece 21 and the fixing band 22, the protective portion 23 is caught on the toe cap portion of the hiking boots and does not leave the lower part of the hiking boots, the close contact piece 21 and the fixing band 22 is the outer shell of the hiking boots The close contact piece 21 and the fixing band 22 are not caught by the upper part of the hiking boots. Therefore, the close contact piece 21 and the fixing band 22 are firmly fixed to the sole of hiking boots, and do not escape from hiking boots.

The elastic body 3 is in the form of a substantially metallic leaf spring, and tightens the contact piece 21 while maintaining the shape of the contact piece 21 so that the elastic member 3 closely adheres to the circumference of the sole. 21) is installed inside. And, when the sole of the hiking boots are bent, the elastic body is divided into front and rear, so that the elastic body can also be bent together, and connects the divided ends by connecting the hinge axis. A description thereof will be described later.

On the other hand, the elastic body 3, as shown in Figure 6, when the sole of the hiking boots are bent together more easily, the bent portion is separated into the elastic body 3 of several nodes, and the hinge shaft ( 31) and can be combined. Thereby, the elastic body 3 bends more easily with the sole of hiking boots, and more comfortable hiking can be performed.

The hinge shaft 31 described above is applied to both the left and right sides of the waterproof portion 2.

Here, the close contact piece 21 is inserted into the elastic body 3 is injection molded.

Therefore, the packing 212 is in close contact with the circumference of the sole while the close contact piece 21 is in close contact with the circumference of the sole by the force tightened by the elastic body 3. That is, the plurality of packings 212 formed of a soft and soft material are in close contact with the periphery of the sole to completely fill the gap between the hiking boots, so that the tight contact 21 and the sole are tightly sealed.

The cover 4 is made of a waterproof fabric such as vinyl that is easily bent, and is formed in a shape similar to the outer shell of the hiking boots, and wraps the outer cover 21 from the sole of the hiking boots so that the close contact piece 21 and the fixing band 22 are used. It is bonded or bonded to the bonding blades 221 formed in the. In addition, the cover 4 is formed to have a rear so as to be easily detachable from hiking boots, and the detachable part 6 is installed at the cut-out part. A description thereof will be described later.

The detachable part 6 (hereinafter referred to as 'velcro') is provided at the other end of the fixing band 22 and the cutout of the cover 4 so as to open and close the waterproof part 2 and the cover 4. Here, the detachable part 6 is a double-sided tape, Velcro 6, or a snap button, etc., in order to easily open and close the waterproof part 2 and the cover 4, among which Velcro has excellent length control and durability. It is preferable to use (6).

Here, the reason why the cover and the joining blade adopt the high frequency joining method is that, for example, when the cover and the joining wing are sewn, a needle hole may be formed and water may penetrate into the hole. Therefore, it is preferable to perform the high frequency joining without sewing. However, the part where the velcro 6 is to be bonded should be strongly bonded so that the velcro 6 is not easily separated from the cover, so that the adhesive and the adhesive tape are bonded and further sewn to improve the bonding force between the cover and the Velcro 6. It is preferable to make it.

The close support band part 5 includes a cover close help band 52 which prevents the cover 4 from flowing from hiking boots and a top close band 51 which prevents foreign matter from penetrating through the ankle.

The cover adhesion help band 52 is installed in the cover 4 in a substantially vertical or horizontal position at a position corresponding to the instep of hiking boots. In other words, the outer surface of the cover 4 has a function similar to that surrounded by a rubber band. And, the upper contact band 51 is installed on the upper end of the cover 4 to prevent foreign matter from entering the ankle portion. On the other hand, the top contact band 51 is installed on the top of the cover 4 may be a wide band-shaped band is installed, the material is used a soft rubber material such as latex. Accordingly, since the cover tight support band 52 holds the cover 4 at the foot of the hiking boots, the cover 4 is prevented from fluttering or flowing from the wind, and the top sticking band 51 closely adheres to the ankle. By tightening, it is possible to prevent foreign matter from penetrating into the ankle.

Here, the waterproof portion 2 may have a space 213 having both ends of the structure or a structure in which both ends are closed in the interior of the waterproof portion 2 to increase the adhesion around the sole of the hiking boots. Since the structure is easy to deform in the air, the deformation is easy, even if the sole circumference of the hiking boots bend to a certain degree, the waterproof part 2 can be easily adhered to the circumference of the sole, and if both ends are blocked, the air can escape. Since there is no structure, the part with large external pressure is compressed, and the part with low external pressure is expanded so that the gap between the waterproof part 2 and the sole can be effectively filled, thereby improving the sealing effect. That is, when the waterproof part 2 is pressed, the space 213 is deformed to make deformation easier, so that the gap between the waterproof part 2 and the sole can be closely adhered to improve the sealing effect. Accordingly, the airtightness between the sole of the hiking boots and the waterproof portion 2 can be improved to further prevent the penetration of water or foreign matter (see FIG. 5).

Hereinafter, the state of use of the shoe waterproofing apparatus 1 according to an embodiment of the present invention will be described in detail.

First, the Velcro 6 is removed to open the cover 4 and the waterproof part 2, and the cover is opened to cover the hiking boots while moving from the front to the rear of the hiking boots. At this time, the position of the waterproof part 2 is adjusted so that the waterproof part 2 is disposed on the sole of the hiking boots, and the waterproof part 2 is brought into close contact with the sole of the hiking boots by pulling the Velcro 6 installed in the waterproof part 2. After that, the cover 4 is sealed by attaching the Velcro 6 while going up to the top. For example, the close contact piece 21 is in close contact with the elastic body 3 to the sides of the hiking sole, but the front of the outsole may be in close contact with the close contact piece 21. Therefore, the contact piece 21 is pulled closer to the front of the sole, that is, the packing 212 is compressed and deformed while pulling the fixing band 22 to the point of close contact with the front of the sole of hiking boots. Fully adhere to the front and sides of the This is because the sole of hiking boots is often formed to have a flat circumference of the heel portion, but the middle portion and the front portion of the sole may be bent than the heel circumference so that the close contact piece 21 may not be in close contact with the sole. Therefore, the elastic body 3 first tightens the close contact piece 21 and adheres it to the periphery of the sole, and secondly, a plurality of packings 212 are formed on the inner surface of the close contact piece 21, thereby forming a curved or concave shape. Even if there is a part, the packing 212 is deformed to fill the gap between the curved part and the concave part so that there is no gap between the close contact piece 21 and the sole circumference. In addition, the fixing band 22 is in close contact with the rear circumference of the sole because it is excellent in elasticity even without the packing 212 on the inner side of the fixing band 22. In addition, the rear portion of the sole of the hiking boots is relatively less exposed to moisture than the front portion, and the exposed area is also small enough to form the packing 212 on the inner side of the fixing band 22. Accordingly, it is possible to prevent water or foreign matter from penetrating between the fixing band 22 and the sole.

In addition, the cover 4 secures the cover tight support band 52 to the jacket of hiking boots, thereby preventing the cover 4 from flapping by wind or flowing from hiking boots when walking.

Therefore, when the present invention is mounted on the light-ventilated shoe with excellent ventilation, it is possible to prevent rainwater from penetrating by hiking boots even in rainy weather. You can keep hiking.

For example, if you climb in hot weather wearing a conventional waterproof hiking boots that are not well ventilated, the sweat will not be discharged quickly, but the mountain will be uncomfortable. If the rain is stopped, the present invention can be removed from the lamplight and the lamplight is ventilated, thereby maintaining a comfortable hike at all times. In addition, because you can go hiking wearing light boots, even a long hike can ease the burden on the foot. In addition, the present invention is light in weight and small in volume, it is easy to carry, and can be easily mounted and released to hiking shoes, anyone can easily use.
