Description

[Detailed description of the invention] (Field of industrial application) The present invention is a shoe cover that can be worn over shoes or bare feet, especially during rainy weather, to prevent soiling of shoes or bare feet. This invention relates to a shoe cover suitable for covering shoes to prevent them from getting dirty.

(Prior art) Conventional shoe covers of this type have been made by plastic molding rubber, synthetic resin, etc., making the thickness different locally and curving them three-dimensionally to form a shoe last, or cutting them into a predetermined shape. A shoe last is formed by joining a plurality of small pieces with different thicknesses to each other.

(Problems to be Solved by the Invention) Therefore, the conventional shoe covers have been problematic in that they are expensive to manufacture.

(Means for Solving the Problems) The present invention has been proposed to address the above problems, and its purpose is to provide an inexpensive shoe cover.

According to the present invention, the purpose of this is to overlap two flexible flat sheets of polyethylene film, cloth, etc., and connect these two sheets to the instep joining line that extends diagonally downward in the front and to the lower end of this. A toe joint line that extends downward, a plantar joint line that extends downward at the bottom of the foot, and a heel joint line that extends upward at the rear end of the foot; A bag with an open top is created by joining each other along the convex ankle joining line, and the toe joining line and sole joining line are overlapped so as to align from their continuous points, and these are joined. The above-mentioned sheets are joined by a corner joining line that intersects with the line, and the heel joining line and the sole joining line are overlapped so as to align from these continuous points, and a corner that intersects these joining lines is formed. This is accomplished by joining the sheets together at corner joining lines.

(Example) Hereinafter, an example of the present invention will be specifically described with reference to the drawings. 1 to 6 show a first embodiment in which the present invention is applied to a shoe cover for short shoes.

In Fig. 1, 1 and 2 are thin, flat sheets with high flexibility such as polyethylene film, and these two sheets 1 and 2 are stacked on top of each other, and a straight instep joining line 3 extends diagonally downward and forward. , a toe joint line 4 that extends downward continuously from this lower end, a plantar joint line 5 that continues from this lower end and whose approximately center is convex downward, and a heel joint line 6 that continuously extends upward from this rear end. By heat-sealing and joining these two sheets 1 and 2 to each other by the ankle joint line 7 which is continuous and convex to the front at the upper end, a bag with an open upper part is created, and a third As shown in the figure, the toe joining line 4 and the sole joining line 5 are overlapped so as to align from their continuous point A, and these joining lines 4, 5 are formed.
The sheets 1 and 2 are joined by heat fusion using corner joining lines 8 that intersect with each other.
As shown in the figure, the heel joining line 6 and the sole joining line 5 are overlapped so as to be aligned from these continuous points B, and the sheets 1 are connected to each other by the corner joining line 9 that intersects these joining lines 6 and 5. Then, the sheets 2 are joined together by heat fusion. Then, these two sheets 1 and 2 are cut at a cutting line 10 located outside of each of the joining lines 3 to 9, and a foot entrance cutting line 11 extending almost horizontally in contact with the upper ends of the instep joining line 3 and the ankle joining line 7. By cutting, the shoe cover 20 is completed.

When the shoe cover 20 is inserted into the upper opening of the shoe cover 20 and attached to the shoe 21 as shown in FIG. Since it is convex downward, it comes into close contact with the sole of the shoe 21. Since the instep joining line 3 extends diagonally downward and forward, and the ankle joining line 7 is convex forward, the shoe cover 20
engages the upper part of the instep and heel of the shoe 21, and therefore the shoe 2
It will never fall off from number 1. The toe joint line 4 contacts the toe of the shoe 21, and the heel joint line 6 contacts the toe of the shoe 21.
The corner joining line 8 contacts the tip of the sole, and the corner joining line 9 contacts the rear end of the sole.
The shoes 21 rarely move within the shoe cover 20,
Therefore, it is easy to walk.

7 and 8 show a second embodiment of the present invention, which includes a cylindrical material 30 having a predetermined diameter.
A shoe cover 31 for boots is made using the above. By pressing the cylindrical material 30 and folding it in two, a calf joint line 32 that extends upward continuously from the upper ends of the toe joint line 4, heel joint line 6, and ankle joint line 7 is formed in advance. The upper end of the instep joining line 3 is provided with the far shin joining line 34 that extends smoothly and continuously upward via the asymptotic joining line 33, and the foot entrance cutting line 11 extends forward and upward from the upper end of the instep joining line 32. This is different from the first embodiment described above in that it extends obliquely and touches the upper end of the shin joint line 34. This is because the foot entrance cutting line 11 extends obliquely in the front direction, and the far shin junction line 34 is smoothly connected to the instep junction line 3 via the asymptotic junction line 33. The cover 31 can be easily attached and detached. In addition, if the arch joining line 35 is provided inside the sole joining line 5 as shown in FIG. 7, the shoe cover 31 will come into close contact with the arch of the boot, so that the integration of the shoe cover 31 and the boots can be further improved. I can do it. In addition, as shown in FIG. 9, if a chuck 36 is provided on the instep of the shoe cover 31, the shoe cover 31 can be attached and taken off more easily. If the rubber band 37 is stretched, the shoe cover 31
It is possible to further improve the integration between the boots and the boots. Furthermore, if the bottom of the shoe cover 31 is treated with a stopper or a sole is bonded to it, it is possible to prevent the shoe cover from slipping while walking, and further improve the durability of the shoe cover 31.

In the above embodiments, polyethylene films were bonded by heat fusion, but when using sheets such as cloth, they may be bonded by stitching. Further, the tongue piece between each joining line and the cutting line may be placed on the outside of the shoe cover, but it will look better if it is hidden inside the shoe cover by turning it inside out after joining.

(Operations and effects of the invention) The shoe cover of the invention is made by overlapping two flexible flat sheets of polyethylene film, cloth, etc., and connecting these two sheets to the instep joining line extending diagonally downward and forward. , a toe joint line that extends downward continuously from this lower end, a plantar joint line that continues from this lower end and whose approximately center is convex downward, a heel joint line that continuously extends upward from this rear end, and this upper end. A bag with an open upper part is created by joining the toe joint line and the ankle joint line, which is convex to the front, and the toe joint line and the sole joint line are overlapped so as to be aligned from these continuous points. At the same time, the above-mentioned sheets are joined together by corner joining lines that intersect with these joining lines, and the above-mentioned heel joining line and sole joining line are overlapped and joined from these continuous points so that they are aligned. Since it is constructed by joining the above-mentioned sheets together using corner joining lines that intersect with the lines, it is simple and easy to manufacture, and is therefore extremely inexpensive, making it widely available for disposable use or for free provision. Can be used generally. Moreover, despite its simple structure, it is easy to put on and take off from shoes, and when it is attached to shoes, it does not fall off from shoes, making it easy to walk.
