Description

Stretchy waterproof shoe cover

The present invention relates to a waterproof shoe cover that waterproofs the shoes by wearing them on shoes such as work safety shoes, hiking shoes, sneakers, golf shoes, and everyday shoes. More specifically, it relates to a waterproof cover for shoes made of latex, silicone, nitrile rubber, etc. It is made of an elastic material that not only adheres completely to the shoe and provides excellent waterproofing even in rainy weather, but also allows the bottom of the sole of the shoe to be directly grounded on the road surface, so it has an improved elastic shape to enable stable walking. will be.

In general, when work is performed in rainy conditions at construction sites, industrial sites, etc., if water gets into safety shoes, workers easily become tired and require a lot of effort to perform the work, which not only reduces work efficiency but also increases the risk of safety accidents at construction sites. It becomes a cause.

Additionally, if you hike on a rainy day or encounter rain while hiking, rainwater flows into the inside of your hiking boots, causing severe discomfort. In particular, continuing to hike despite this inconvenience is very dangerous as it can adversely affect the health of your feet or cause your feet to slip inside your hiking shoes, causing a safety accident.

To solve this problem, patches (gaiters, footsocks) that cover the ankle and part of the upper part of the shoe to prevent rainwater from flowing into the shoe were used.

As a prior document regarding such a conventional spatch, Public Utility Model No. 20-2010-0002117 includes a waterproof sheet formed in a fan shape to cover the user's ankle, the entrance of the hiking boots, and the part where the laces of the hiking boots are fastened, and both ends of the waterproof sheet. Hiking shoes configured to include a first adhesive member provided on the first adhesive member, a hook provided in the center of one side of the waterproof sheet, an elastic band for tightly attaching the top of the waterproof sheet to the ankle, and a fixing band and fixture protruding from both sides of the waterproof sheet. A waterproof cover for use is disclosed.

However, in the case of this spatch, since it does not cover the entire shoe but only covers a portion of the upper part of the shoe, it cannot prevent rainwater from seeping into the joint between the sole and the upper, making it difficult to demonstrate practical waterproofing function.

In addition, in order to fix the spatch to the shoe, a shoe fixing band is provided that wraps around the sole of the shoe, but when walking on construction sites, industrial sites, hiking trails, etc., the shoe fixing band is easily damaged by stones on the floor or rough road surfaces. It was broken and damaged, causing it to lose its function or shorten its useful life. In addition, because the overall spatch components were made of various materials and had a complex structure, the manufacturing cost was significant and there were difficulties in handling and storage after climbing.

On the other hand, when golf shoes are exercised in the early morning, dew on the grass, etc., penetrates into the inside of the golf shoes, causing wet socks, causing discomfort and having a negative effect on golf games, which are sensitive to scores. However, no method to solve this situation has been devised to date.

Public Utility Model No. 20-2010-0002117

This invention was created to solve the conventional problems as described above. It is made of highly elastic latex, silicone, and nitrile rubber materials, so it is easy to manufacture and has excellent productivity, and is suitable for all shoes except the bottom of the sole. It is easy to wear by wrapping the part, and it adheres completely to the shoe in a contracted state, so it has excellent adhesion and does not come off. In addition, the bottom of shoes such as safety shoes, hiking boots, and sneakers are directly connected to the road surface, so it is stable and does not cause inconvenience to walking. The purpose is to provide a waterproof shoe cover with elasticity and an improved form that allows walking.

However, the purpose of the present invention is not limited to this, and of course, even if not explicitly mentioned, purposes or effects that can be understood from the means of solving the problem or the embodiment are also included.

The elastic shoe waterproof cover of the present invention for achieving the above-described purpose includes a sole side cover that is closely fixed to the edge side of the shoe sole, and an integral extension to the top of the sole side cover, thereby tightly fixing the entire shoe upper. It consists of a shoe cover part made of an upper cover, and an ankle cover part that extends integrally to the top of the upper cover to tightly fix the user's ankle, and the shoe cover part and the ankle cover part are made of an elastic sheet material to protect against contractile force. It is configured to adhere closely to the shoe, and the bottom of the shoe sole is exposed to the outside to provide direct contact with the road surface, and the bottom is open so that the user's foot can pass through so that the user can put the shoe on the ankle first before putting it on. It is characterized by a hall.

The bottom front portion of the sole side cover may be integrally formed with a cover fixing portion that is tightly fixed to the bottom front portion of the shoe sole and prevents the sole side cover from peeling off toward the top of the shoe.

The thickness of the sheet forming the shoe cover portion and the ankle cover portion is preferably 0.1 to 1 mm.

It is configured to connect both lower sides of the sole side cover to the middle portion in the front and rear longitudinal direction of the sole side cover, and is fixed in close contact with a groove portion not in contact with the ground formed in the middle length of the bottom of the shoe sole, so that the sole side cover is attached to the upper side of the shoe. A cover fixing band may be provided to prevent peeling off.

According to the above, the present design is made of a single material of latex or silicon and is worn in complete contact with the shoe and ankle by stretching, so not only is the waterproof performance very excellent, but it can be firmly fixed without being easily peeled off. , an opening hole is formed in the bottom so that the bottom of the shoe can be exposed to the outside and directly exposed to the road surface. The sole of the shoe, such as safety shoes, hiking boots, or sneakers, touches the road surface directly, allowing you to walk stably without discomfort. I do it.

In other words, if the waterproof cover is covered with latex or silicone all the way to the bottom of the shoe, it not only makes walking uncomfortable, but the bottom contact surface is not strong, so the latex or silicone can be easily torn or damaged by rough road surfaces such as rocks or gravel. However, the shoe waterproof cover of the present invention is pierced into the floor by a bottom opening hole, so the sole of the shoe contacts the road surface directly, allowing the wearer to maintain stable walking while maintaining the grip on the road surface. Safety can be ensured.

In addition, since the present invention is manufactured by molding a single material of latex or silicon, it is not only easy to manufacture, but also can lower the product price. It is also lightweight by reducing the overall weight of the product, making it convenient to carry, improving storage and ease of use. This has an improving effect.

This waterproof shoe cover of the present invention can improve work efficiency by preventing safety shoes and socks from getting wet in the rain even when working all day in the rain at industrial sites such as construction sites and loading/unloading sites, and can be applied to hiking boots to enable safe mountain climbing in rainy weather. In addition, it can be useful in general life, including during early morning golf rounds and students going to school in rainy weather, and can also be very convenient and useful when camping in rainy weather.

In particular, when the waterproof shoe cover of the present invention is used on golf shoes, it can maintain the function of the spikes on the sole of the golf shoe while securing a waterproof function that prevents the socks from getting wet, which has the effect of improving performance during early morning golf games or rainy weather games. There is.

In addition, the waterproof shoe cover of the present invention can be applied to regular shoes and sneakers worn by office workers or students in rainy weather. The product's simplicity and lightness, small size make it easy to carry, and it is convenient to wear, making it easy to use. It works.

In addition, the various and beneficial advantages and effects of the present invention are not limited to the above-described content, and can be more easily understood in the process of explaining specific embodiments of the present invention.

The above objectives, features and advantages of the present invention will be easily understood through the following preferred embodiments related to the attached drawings. However, those skilled in the art will be able to understand through the embodiments described later that the present invention is not limited to the embodiments described herein and can be embodied in other forms.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the attached drawings. In describing specific embodiments below, various specific details have been written to explain the design in more detail and aid understanding. In addition, it is mentioned in advance that in describing the design, parts that are commonly known but largely unrelated to the design are not described to prevent confusion in explaining the present design.

With reference to FIGS. 1 to 4, a shoe waterproof cover 1 according to a first embodiment of the present invention will be described.

The shoe waterproof cover (1) of the present invention is configured to tightly cover the entire outer surface of the shoe except for the bottom of the sole (sa) of the shoe (s) to make it completely waterproof.

The shoe waterproof cover (1) is in the form of a boot with a hole in the bottom, and is configured to include a shoe cover portion (10) and an ankle cover portion (20) that are integrated with each other.

The shoe waterproof cover 1 can be manufactured by molding a single material of either latex rubber or silicone rubber, which are materials with excellent elasticity. The shoe waterproof cover (1) may be manufactured by various rubber molding methods such as injection molding, compression molding, extrusion molding, or calendering molding of either latex or silicone.

The shoe waterproof cover (1) of the present invention can be molded into a boot with an open bottom using latex rubber or silicone rubber. After molding it into a normal boot with a bottom, a cutting process is added to cut the bottom. It can also be manufactured.

The shoe cover portion 10 includes a sole side cover 12 that is closely fixed to the edge side of the shoe sole, and an upper cover that extends integrally from the top of the sole side cover 12 and tightly secures the entire shoe upper sb. It consists of (13).

The ankle cover portion 20 extends integrally to the upper side of the upper cover 13 and is configured to closely secure the user's ankle.

In addition, the shoe cover part 10 has an open bottom, so that a bottom opening hole 11 is formed through the lower surface. When the shoe cover 10 is worn on a shoe, the bottom of the shoe sole is exposed to the outside through the bottom opening hole 11, so that the bottom of the shoe sole is directly in contact with the road surface when walking, allowing stable walking.

In the present invention, the shoe cover portion 10 is preferably configured to be smaller than the size of the shoe to be used. Since the shoe cover part 10 is configured to have an external shape smaller than the shoe size, when the shoe cover part 10 is stretched and covered with a shoe, the shoe cover part 10 can be completely adhered to the shoe by its own contraction force. Likewise, the ankle cover part 20 is preferably configured to be smaller than the thickness of the user's ankle, so that when the ankle cover part 20 is stretched and inserted into the ankle, it can be closely attached to the ankle.

The shoe waterproof cover (1) of the present invention can be manufactured in various ways to suit the size and shape of the shoe.

In the present invention, the shoe cover part 10 is preferably configured to have an external size that is 80 to 90% smaller than the external size of the shoe to be used. If the shoe cover part (10) is smaller than 80% of the external size of the shoe, it is very difficult to stretch it enough to cover the shoe with the shoe cover part (10), and the shoe cover part (10) is 90% smaller than the external size of the shoe. If it is configured to have an external size that exceeds the external size, it is easy to put the shoe cover part 10 on the shoe and wear it with less effort. However, even if it is used only a few times, the shoe cover part 10 stretches and does not adhere properly to the shoe, making it waterproof. There is a problem of weakening the function.

In addition, the shoe waterproof cover (1) of the present invention is composed of an elastic sheet material made of a single material of latex or silicone, and this elastic sheet, that is, the shoe cover part (10) and the ankle cover part (20), is composed of The thickness of the sheet is preferably 0.1 to 1 mm.

In the above, the shoe waterproof cover (1) of the present invention has been described as being made of an elastic sheet material such as latex or silicone, but it is not limited thereto, and is made of an elastic synthetic rubber such as nitrile rubber. Of course, it can be made of various elastic sheet materials.

If the thickness of the sheet constituting the shoe cover part 10 and the ankle cover part 20 is less than 0.1 mm, it will be easily torn when stretched for wearing, and if it exceeds 1 mm, it will not be easily torn even if stretched for wearing. However, it takes too much force for the user to stretch it and it is not easy to wear.

In the present invention, the sole side cover 12 is integrally formed with a cover fixing portion 14 on the lower front side that is tightly fixed to the bottom of the sole front end of the shoe. When the sole side cover 12 is worn in close contact with the side of the shoe sole, the cover fixing part 14 is tightly fixed to the front end of the shoe sole, so that even if the sole side cover 12 tries to peel off toward the top of the shoe, the cover fixing part 14 (14) is caught on the front of the sole of the shoe, preventing the sole side cover (12) from coming off arbitrarily onto the shoe.

The cover fixing part 14 preferably has a front-to-rear length of 1 to 3 cm. If the cover fixing part (14) is less than 1cm, it may not be easily caught on the front of the shoe sole and the sole side cover (12) may come off. If it is more than 3cm, it may be easily caught on the front of the shoe sole and the sole side cover (12) may be removed. Although it does not come off clearly, there is a problem that the rear end comes into contact with the road surface, preventing comfortable walking and being easily damaged.

In the present invention, since the bottom opening hole (11) is formed on the lower surface of the shoe cover part (10), even if the shoes are not worn first, the shoe waterproof cover (1) of the present invention can be placed on the ankle before putting the shoes on. At this time, the user's feet can pass through the bottom opening hole (11) and the shoe waterproof cover (1) can be placed on the ankle.

In this design, before putting on the shoes, the shoe waterproof cover (1) is placed on the ankle in advance, and then after wearing the shoes, the shoe waterproof cover (1) worn on the ankle is lowered to remove the shoe cover (10). A wearing method may be used in which the shoe is worn by putting it on a shoe and the ankle cover part 20 is worn on the user's ankle.

However, it goes without saying that the wearing method of the shoe waterproof cover 1 can be arbitrarily changed by the user. That is, while the user is wearing the shoes, the shoes can be worn and used through the upper opening of the shoe waterproof cover (1).

Meanwhile, with reference to FIG. 5, a waterproof shoe cover 1' having elasticity according to a second embodiment of the present invention will be described. In the description of the shoe waterproof cover 1' in the second embodiment, the same configuration as the shoe waterproof cover 1 of the first embodiment shown in FIG. 3 is not described, only the same reference numerals are given, and the differences are given. We will only explain the configuration.

The lower outer peripheral surface of the ankle cover part 20 is configured to form a predetermined groove, and a lower ring fixing groove 31 is formed to engage the lower elastic pressure ring 32, and the upper outer peripheral surface of the ankle cover part 20 It is configured to be in the shape of a predetermined groove and is formed in a shape corresponding to the first ring fixing groove 31, and an upper ring fixing groove 33 is formed to engage the upper elastic pressure ring 35.

In addition, the ankle cover portion 20 is formed on the inner surface between the lower ring fixing groove 31 and the upper ring fixing groove 33 to be spaced apart at predetermined intervals up and down, so that it adheres closely to the ankle and prevents moisture from flowing down the ankle. It consists of an upper moisture blocking ring (37) and a lower moisture blocking ring (38).

The present invention is inserted and coupled to the lower ring fixing groove (31) to surround the ankle cover part (20), so that the lower side of the ankle cover part (20) is closely adhered to the ankle, and the lower moisture blocking ring (38) presses the lower side of the ankle to ensure tightness. The lower elastic pressure ring 32, which increases the pressure, is inserted and combined with the upper ring fixing groove 33 to surround the ankle cover part 20, so that the upper side of the ankle cover part 20 adheres to the ankle and the upper moisture blocking ring. (37) may be configured to further include an upper elastic pressure ring 35 that presses the upper side of the ankle to increase adhesion.

Meanwhile, the present design is fitted between the upper moisture blocking ring 37 and the lower moisture blocking ring 38, and includes a moisture absorbing member (40) that contacts the ankle and absorbs sweat generated from the ankle or moisture flowing down the ankle. ) can be further configured. This moisture-absorbing member 40 may be made of moisture-absorbing fiber.

Hereinafter, with reference to FIGS. 6 to 8, a waterproof shoe cover with elasticity according to a third embodiment of the present invention will be described.

The shoe waterproof cover of the third embodiment is different from the first embodiment in that a fixing band 16 for covering the sole side cover 12 is further formed at the bottom of the sole side cover 12. Accordingly, the same configuration of the shoe waterproof cover 1 of the first embodiment will not be described, but only the same reference numerals will be assigned and only the different configurations will be described.

The cover fixing band 16 is configured to connect both lower ends of the sole side cover 12.

The cover fixing band 16 may be made of a single material such as latex rubber or silicone rubber, which are materials with excellent elasticity. The cover fixing band 16 may be made of the same material as the sole side cover 12 and the upper cover 13, or may be made of a different material.

In the present invention, the cover fixing band 16 may be molded integrally with the sole side cover 12 when molding the shoe waterproof cover 1, or may be formed separately and formed at both ends of the sole side cover 12 after molding the shoe waterproof cover 1. It may be configured by bonding to both sides of the bottom of the cover 12 using an adhesive or the like.

The cover fixing band 16 is composed of the middle part in the front and rear longitudinal direction at the bottom of the sole side cover 12, and is closely fixed to the middle part of the length of the bottom of the shoe sole, and is attached to the sole side cover 12 together with the cover fixing part 14. This can further prevent the top of the shoe from peeling off.

At this time, the cover fixing band 16 is located between the forefoot part (t) and the heel (h) of the bottom of the shoe sole, and is attached to the ground non-contact groove part (g) formed in front of the heel (h) of the shoe, which does not contact the ground when walking. It is constructed to adhere closely.

That is, when the shoe waterproof cover of the present invention is used on a shoe with a heel, the cover fixing part 14 is tightly fixed to the bottom of the front end of the sole, and the cover fixing band 16 is a groove part of the shoe sole that is not in contact with the ground ( By being closely fixed to g), even if the sole side cover 12 tries to peel off toward the top of the shoe, the cover fixing part 14 is caught on the sole of the shoe, preventing the sole side cover 12 from coming off arbitrarily onto the shoe.

In particular, the cover fixing band 16 is configured to be in close contact with the ground non-contact groove portion (g) formed in the middle length of the bottom of the shoe sole, so that the cover fixing band 16 does not come into contact with the ground even when walking, so it can be used for a long time. It can be used semi-permanently without being broken or damaged even after use.

In the present invention, both the cover fixing part 14 and the cover fixing band 16 may be configured, or only the cover fixing part 14 may be configured, or only the cover fixing band 16 may be configured alone. .

As described above, the cover fixing band 16 is made of a single elastic band and has both ends connected to the lower sides of the sole side cover 12. However, it is not limited thereto, and as shown in FIG. The cover fixing band 16 of the design is divided into two parts, a first elastic fixing band part 16a connected to one lower end of the two lower sides of the sole side cover 12 and both sides of the sole side cover 12. It consists of a second elastic fixing band part (16b) connected to the other lower part of the lower end, and the first elastic fixing band part (16a) and the second elastic fixing band (16b) are separable from each other by Velcro means (17a, 17b). It can be configured to be combined.

A first Velcro member (17a) is coupled to the lower surface of the distal end of the first elastic fixing band portion (16a), and a second Velcro member that is detachable from the first Velcro member (17b) is attached to the upper surface of the distal end of the second elastic fixing band portion (16b). (17b) is configured to be coupled so that the first elastic fixing band portion 16a and the second elastic fixing band portion 16b are detachably coupled with Velcro.

Accordingly, by adjusting the overlap area where the first elastic fixing band portion 16a and the second elastic fixing band 16b are joined according to the width size of the shoe, the cover fixing band 16 is positioned in the groove portion (g) that is not in contact with the ground of the shoe sole. It can be mounted fixedly in close contact with the.

Above, the present invention has been shown and described in relation to preferred embodiments for illustrating the principles of the present invention, but the present invention is not limited to the configuration and operation as shown and described. Rather, those skilled in the art will be able to understand that many changes and modifications can be made to the present design without departing from the spirit and scope of the attached utility model registration claims. Accordingly, all such appropriate changes, modifications and equivalents should be considered to fall within the scope of the present invention.
