Description

Our Ref: 4916Inno P/00/009 Regulation 3.2 AUSTRALIA Patents Act 1990 INNOVATION SPECIFICATION FOR AN INVENTION ENTITLED Invention title: A water proof shoe cover Name of Applicant: Wai Kwan Chan Address for Service A.P.T. Patent and Trade Mark Attorneys PO Box 222 Mitcham, S.A. 5062 The invention is described in the following statement: A water proof shoe cover Technical field This utility patent is a waterproof item. To be specific, it is a waterproof shoe cover that is easy to wear. Background technology At raining time, people usually wear rain boots when going outdoors to prevent their pants and feet from getting wet. These rain boots are usually made from rubber. They usually have sole, upper, vamp, and boot trunk that sow together with upper and vamp. The sole, upper, and vamp form the shoe body to contain the user's feet. The front of the sole is the toe tip, and the back is the heel. Upper is attached with the latter part of the sole to from the mouth so that the users can put their feet into the shoe chamber. Vamp attached to front part of the sole. One end of the boot trunk is attached to the shoe mouth and the other end is opened up to the user and matches the user's leg to protect their pants. To be waterproof, these boots must be sealed well. That makes their ventilation very poor. It is not comfortable to wear them. And they don't look pretty. Furthermore, the user has to take off the original shoes to wear them, which is not convenient. Thus they are only worn when there is a heavy rain. People usually take comfortable shoes with them when using the boots, so that they can replace the boots indoor, such as in the office. In addition, the boot trunk usually cannot be folded, making it difficult to take the boots along. Content of the utility patent The technical issue that this utility patent will resolve is: to resolve the current rain boots' issue of difficult to take along and difficult to replace, and to provide a waterproof shoe cover that does not require the user to take off the original shoes and is easy to take away. The technical solution provided by this utility patent to resolve the said technical issue is: to provide a waterproof shoe cover, which includes sole, upper, vamp, and boot trunk. The sole, upper, and vamp form the shoe body to match with the user's shoes. The upper, vamp, and 2 boot trunk are made from soft materials. On the upper of the shoe, close to the heel, there is a rear elastic that will tighten the upper closely to the upper of the user's shoes. On the vamp close to the tip there is a front elastic that will tighten the vamp closely to the vamp of the user's shoes. In the waterproof shoe cover defined by this utility patent, on the upper of the shoe, close to the heel, there is an elastic. Both ends of the said elastic are attached to the center of the upper, near the sole, close to the heel. This elastic can be set on different positions according to the different heights of the shoe heels of the user. This is extremely useful when dealing with woman's high heels. In the waterproof shoe cover defined by this utility patent, there is a heel mouth on the sole at the position corresponding to heel's position where woman's high heels are. This heel mouth can help woman's high heels pass through the sole of shoe cover outside. Thus it can reduce the quick wear and tear on that position caused by the direct pressure from woman's high heels. In the waterproof shoe cover defined by this utility patent, there is a fifth elastic around the said heel mouth. Thus it is possible that the heel mouth can retract around the high heels of the woman's shoes, preventing the water on the ground from entering the shoe cover's chamber. In the waterproof shoe cover defined by this utility patent, there is a shoe tip mouth on the vamp on the tip. There is elastic rubber cap covering around the said tip mouth. Usually, woman's shoes come with sharp tips of different sizes. By setting elastic rubber cap over the tip mouth, tips of different sizes can all be placed into the chamber of the shoe cover. Normally, sharp tips are not weight bearing. They are for ornament only. By setting the sole tip of the shoe cover round instead of sharp, the bearing point of the shoes with sharp tips will be right on the shoe cover's sole, further avoiding slippery when walking. In the waterproof shoe cover defined by this utility patent, there is vertical opening on the said boot trunk. There are zips or buttons on the vertical opening so that it is easy for the users to get their original shoes to get in into the shoe cover while wearing them. In the waterproof shoe cover defined by this utility patent, there is a containing bag to store the whole shoe cover that is attached to the said boot trunk via rope or button. 3 In the waterproof shoe cover defined by this utility patent, there is a storage hole on the inner side of the said boot trunk to store the said containing bag. In the waterproof shoe cover defined by this utility patent, there are fourth elastics around the mouth of the boot trunk to tighten up the boot mouth. The waterproof shoe cover defined by this utility patent has many benefits. By using soft material to make the upper, vamp, and boot trunk, the whole shoe cover can be packed up. By matching the space formed by the sole, upper, and vamp to match the user's shoes, the user can directly wear the shoe cover with his/her original shoes on. There is no need to the user to take off the original shoes to put it into the shoe cover. It is very convenient to use. Thus, when raining, the user can wear the original shoes and put on the shoe cover. When indoor, the user can directly take off the waterproof shoe cover and fold it to store. There is no need to change shoes. Thus it is very convenient. Besides, there is front elastic on the vamp. When the users put their feet into the chamber with their shoes, the front elastic, under its own binding force, will change the vamp's shape to fit onto the vamp of the shoes. Similarly, the back elastic will bind the upper to fit onto the upper of the users' shoes. Thus the users' shoes will be fit in the chamber of the shoe cover tightly without getting loose. The users will not feel slippery when walking with this waterproof shoe cover on. Besides, the chamber of this waterproof shoe cover can fit into different sizes of shoes, making it very universal. The following section will illustrate this utility patent with implementation examples. Figures Figure 1 is the structural view of the first implementation of the waterproof shoe cover of this utility patent. Figure 2 is the structural view of the first implementation of the waterproof shoe cover of this utility patent when its boot trunk is unzipped and the protective cover is removed. Figure 3 is the structural view of the first implementation of the waterproof shoe cover of this utility patent when its storage bag is opened up. 4 Figure 4 is the structural view of the second implementation of the waterproof shoe cover of this utility patent. Figure 5 is the structural view of the second implementation of the waterproof shoe cover of this utility patent when the elastic moves up. Figure 6 is the structural view of the sole of the second implementation of the waterproof shoe cover of this utility patent. Implementation As shown in Figure 1, 2, and 3, the first implementation of the waterproof shoe cover of this utility patent includes sole 1, upper 2, vamp 3, and boot trunk 4. The upper 2, vamp 3, and boot trunk 4 are made from soft materials, such as waterproof plastic, into one piece. Sole 1 is made from strong friction bearing materials such as rubber. The sole 1, upper 2, and vamp 3 form the shoe chamber to match with the user's shoes. The front end of the sole 1 is shoe tip 1 a. The rear end of sole 1 is the heel 1b. One side of upper 2 attaches to the rear half of sole 1 and the other side attaches to the lower end of the boot trunk. The upper end of the boot trunk 4 is the boot mouth 4a, which allows the user to put their feet into the waterproof shoe cover. Vamp 3 attaches to the front half of sole 1, and attaches to upper 2 to form the shoe chamber 7 that has an opening at the rear end. There are several places that elastic is used in the waterproof shoe cover defined by this utility patent. The said elastic is a long narrow flat belt that is elastic lengthwise. By placing elastic on the surface of the soft material, especially by sewing it on the surface of the soft material, the surface of the soft material can fold up. When sewing together, the elastic should be stretched out to get sewed to the surface of the soft material. When the elastic retracts back, it is attached to several sewing points on the surface of the soft material. Thus it will retract with these sewing points. This way the surface of the soft material will retract too, so the size of this position will be reduced. As shown in Figure 2, there is a rear elastic 9 on the upper 2 near heel 1 b. To be specific, rear elastic 9 can be sewed to on the upper 2 near sole 1. This way, when the users put their feet into the shoe chamber 7 of the waterproof shoe cover with their shoes, the rear elastic 9 will retract to fold part of the upper 2 of the waterproof shoe cover. It reduces the size of shoe 5 chamber 7 at this position, so that the upper 2 of the waterproof shoe cover can be attached tightly to the upper of the user' shoes. Similarly, there is a front elastic 8 on the vamp 3 near show tip 1 a. Specifically, the front elastic 8 can be sewed to the vamp 3 near sole 1. Thus the vamp 3 of the waterproof shoe cover can fold up to reduce the size of shoe chamber 7 at this position. Thus the vamp 3 of the waterproof shoe cover can attach to the vamp of the users' shoes closely. With the joint effort of front and rear elastics 8 and 9, the chamber 7 of the waterproof shoe cover can match perfectly into the users' shoes. Thus the users' shoes can fit tightly into the chamber 7 of the waterproof shoe cover, to prevent the shoes from sliding inside the chamber 7 of the waterproof shoe cover. In this implementation, since upper 2, vamp 3, and boot trunk 4 are made into one piece, when sealing the one piece upper 2 and vamp 3 onto sole 1, there are some scraps left. To prevent the scrap from affecting the appearance of the shoe cover, they can be turned outside upper 2 and vamp 3 to form protection layer 10. Around the mouth of the protection layer 10 there is a third elastic 11 to make sure the mouth of the protect layer attaches to the outside of upper 2 and vamp 3. As shown in Figure 4, 5, and 6, the second implementation of the waterproof shoe cover of this utility patent includes sole 1, upper 2, vamp 3, and boot trunk 4. This implementation mostly aims at occasions where the users' shoes are woman's shoes. Similarly, there is a front elastic 8 sewed to the surface of upper 2 near the shoe tip 1a. And there is a rear elastic 9 sewed to the surface of the vamp 3 near the heel 1b. In this implementation, there is a flexible elastic 12 on the surface of upper 2 near heel 1 b. Both ends of the said elastic 12 are attached to the center of the upper but its center is not attached to the upper 2. It is possible to sew both ends of the said elastic 12 to the upper 2 near sole 1, or even directly to sole 1. Since woman's shoes usually has a high heel, and the vamp on top of the heel usually leans forward, when the users' shoes get into the chamber 7 of the waterproof shoe cover, the center of the elastic 12 can be moved up to the upper of the woman's high heel shoes so that the heels of the woman's shoes is pressed on the sole 1, preventing the woman's shoes from moving up and down inside the chamber 7 of the waterproof shoe cover, and preventing the woman's shoes from moving back and forth inside the chamber 7 of the waterproof shoe cover with the help of the front elastic 8. 6 Because woman's shoes usually have high heels, when they are directly placed into the chamber of the waterproof shoe cover, the high heel of the woman's shoes press directly over the sole 1 of the waterproof shoe cover. The whole weight of the user is concentrated on the small portion of the sole. Thus sole 1 will quickly wear out. As shown in Figure 6, in this implementation, there is a heel mouth 13 on the sole 1 at the position corresponding to heel's position 1 b where woman's high heels 1 b' are. When the user gets the woman's shoes into the chamber 7 of the waterproof shoe cover, the woman's high heels 1 b' can pass through the heel mouth 13 on the sole 1 of the waterproof shoe cover to the outside of chamber 7. Thus it can avoid the wearing on the sole 1 from woman's high heels 1 b'. In this implementation, the material of sole 1 near heel 1b is made from soft material. The fifth elastic 14 is set around the said heel mouth 13. Thus heel mouth 13's size matches the size of the woman's high heel 1b's size, preventing rain water from entering the chamber 7 of the waterproof shoe cover from the heel mouth 13. Besides, since some woman's shoes have a sharp tip, and since the size of the tips are quite different due to the large variety of woman's shoes, the sole 1 of the waterproof shoe cover has to be adaptive to different sizes. In this implementation, there is a shoe tip mouth 16 set on the vamp 3 near the tip 1 a. There is elastic rubber cap 15 covering around the said tip mouth 16. The said elastic rubber cap 15 covers the tip mouth 16 to prevent rain water from entering the chamber 7 of the waterproof shoe cover through tip mouth 16. When different sizes of shoe tips are placed into the chamber 7 of the waterproof shoe cover, the elastic rubber cap 15 can change its size and shape according to the size and shape of the shoe tip, thus be adaptive to the tip of different woman's shoes. In this implementation, there are fourth elastics 17 sewed around the mouth of the boot trunk 4a. This fourth elastic 17 can retract to reduce the size of boot trunk mouth 4a so that boot trunk 4 can stick to the leg of the user tightly. This protects the user's pants from water, and also prevents boot trunk 4a from slipping down. In this implementation, there is vertical opening 18 on the said boot trunk 4 to help the user getting her feet into the chamber 7 of the waterproof shoe cover. There are zips or buttons on the vertical opening 18 for closing the vertical opening 18. It helps the opening and closing of vertical opening 18, so that the user can quickly put on or take off the waterproof shoe cover. 7 In this implementation, there is a containing bag 19 to pack and store the whole waterproof shoe cover. This bag can be attached to the said boot trunk 4 via rope 20 or button. It is also possible to set a storage hole 21 on the inner side of the said boot trunk to store the said containing bag through this storage hole 21. In this implementation, the said front and rear elastics can be set the same way as the said elastic, i.e., both ends of the elastics can be set on the sole. The center of the elastics is not fixed on the upper or vamp so that the user can wear different sizes and shapes of shoes. The abovementioned implementations are some possible implementations of this patent. They have a relatively detailed description. However, this should not be interpreted as limiting the scope of this patent. For normal technical person in this field, it is possible to make further adjustments and improvements based on this patent's ideas. These are all covered by the patent protection. Therefore, the protection scope of this patent should be based on the attached claims. 8
