Description

The present invention relates to a foot cover attached to a foot to which a cast or bandage is attached.

When a cast or bandage is attached to a foot due to a fracture or the like and a shoe cannot be worn, the cast or bandage directly touches the ground or the like and becomes dirty, which is unsanitary.
If you attach a household garbage bag or a supermarket shopping bag to your feet, you can prevent the cast and bandage from getting dirty, but in the first place these bags are not supposed to be attached to your feet and are not easy to attach to your feet. There is a problem that people are concerned about the appearance.

Therefore, it is conceivable to attach a dedicated foot cover to a foot to which a cast or bandage is attached. Specific examples thereof are described in Patent Documents 1 and 2, for example.
Patent Document 1 describes a foot cover in which a foot is formed by mixing a stretchable material or a rubber body, and is fixed to the foot by a tightening force of the foot.
Moreover, since the foot cover of patent document 2 is equipped with the structure which a wear mouth spreads by removing a planar fastener, it can insert a foot | leg in a foot cover easily.

However, since the foot cover of Patent Document 1 is fixed to the foot mainly by tightening the mouth, there is a problem that the foot cover is easily displaced from the knee or shin and the foot cover is easily detached from the foot.
In addition, the foot cover of Patent Document 2 is designed to be fixed to the foot by placing the mouth mouth narrowed by the bonding of the pair of planar fasteners in the vicinity of the ankle, so that the mouth mouth is above the ankle, For example, when a simple design change placed on the shin is performed, a problem arises that the mouth cover slips off and the foot cover is easily detached from the foot, as in Patent Document 1.
The present invention has been made in view of such circumstances, and an object of the present invention is to provide a foot cover in which slipping of the wearing mouth is suppressed.

A foot cover according to the present invention that meets the above object comprises a shoe sole and an upper connected to the shoe sole, wherein the upper is attached to a foot to which at least one of a cast and a bandage is attached. It is formed of a plastic having a thickness of 0.05 mm or more and 0.30 mm or less, and more than half is transparent or translucent.

In the foot cover according to the present invention, the upper includes a cover body in which one side and the other side of the plastic sheet are connected by a plurality of adhesive portions A, and a gap is provided between the adjacent adhesive portions A. The pores B are preferably formed.

In the foot cover according to the present invention, it is preferable that the shoe sole and the upper are connected by a plurality of adhesive portions C, and a vent hole D is formed by providing a gap between the adjacent adhesive portions C.

In the foot cover according to the present invention, it is preferable that a plurality of pinholes are formed in the upper.

In the foot cover according to the present invention, it is preferable that a deodorant is kneaded into the plastic.

In the foot cover according to the present invention, since the upper is formed of a plastic having a thickness of 0.05 mm or more and 0.30 mm or less, the upper has sufficient rigidity to keep the shape of the upper, and the shape of the upper is It is possible to reliably suppress slipping off of the mouth caused by the deformation.
In addition, since the upper is more than half transparent or translucent, for those who are close to the person wearing the foot cover, the foot with the cast or bandage attached is stably visible through the foot cover, Contact with the foot wearing the foot cover can be prevented.

It is a side view which shows the state which mounted | wore the leg | foot cover which concerns on one embodiment of this invention. It is a front view of the same leg cover. It is a side view of the same leg cover. It is a bottom view of the foot cover.

Next, embodiments of the present invention will be described with reference to the accompanying drawings for understanding of the present invention.
As shown in FIGS. 1 to 4, a foot cover 10 according to an embodiment of the present invention includes a shoe sole 11 and an upper 12 connected to the shoe sole 11, and includes at least one of a cast 13 and a bandage. It is attached to the attached foot 14. This will be described in detail below.

As shown in FIGS. 1 to 3, the upper 12 is designed to stand up from the shoe sole 11, covers at least the upper and ankles of the foot 14, and a mouth 15 is formed at the upper end where the foot 14 is inserted and removed. ing.
The upper 12 is entirely formed of plastic (polyethylene in the present embodiment). The entire upper 12 is formed of plastic in order to simplify the manufacturing process of the upper 12 and reduce the manufacturing cost of the foot cover 10. In the present embodiment, the shoe sole 11 is formed of the same material as the plastic forming the upper 12, and the manufacturing cost of the foot cover 10 is further reduced.

The upper 12 is transparent or translucent as a whole, and the inside of the foot cover 10 is visible from the outside via the upper 12. As a result, the person wearing the foot cover 10 can visually prevent the person nearby who is wearing the foot cover 10 and the band 14 from being attached to the foot 14 to prevent contact with the foot 14. Can be made.
In the present embodiment, the entire upper 12 is transparent or translucent. However, if more than half of the upper 12 is transparent or translucent, other portions may be opaque. This is because if the region of more than half of the upper 12 is transparent or semi-transparent, the foot 14 in the foot cover 10 can be stably recognized from the outside.
Here, the term “transparent or translucent” means that the average light transmittance at a wavelength of 450 to 600 nm in the visible light region is in the range of 40 to 100%. 12, it is confirmed that the inside of the foot cover 10 can be visually recognized stably.

Further, the upper 12 has a rigidity capable of maintaining a shape in which the entirety from the lower end to the upper end of the upper 12 stands up from the shoe sole 11. If the shape of the upper 12 as a whole is not raised from the sole 11, the wearer 15 is slipped off and the foot cover 10 is easily detached from the foot 14. Therefore, the entire upper 12 is kept as if it is raised from the sole 11. This is effective in preventing the foot cover 10 from coming off the foot 14.

In the present embodiment, the design is such that the foot cover 10 is attached to the foot 14 with the mouth 15 placed between the knee and ankle, specifically, the distance from the mouth 15 to the sole 11 is 10 cm to The 50cm design is adopted. This is due to the fact that it has been confirmed through research that there are many requests for the design from those who need to install the foot covers.
In order to keep the entire upper 12 standing from the shoe sole 11, it is needless to say that the rigidity of the upper 12 needs to be increased as the distance from the shoe sole 11 to the mouth 15 is longer.

Here, as a result of various verifications, a shoe employing a design in which the wear mouth 15 is disposed immediately above the ankle (for example, 2 cm above the ankle) when the thickness of the plastic forming the upper 12 is less than 0.05 mm. It has been confirmed that even if the distance from the bottom 11 to the shoe mouth 15 is shortened, the entire upper 12 may not be able to maintain the shape rising from the shoe sole 11.
On the other hand, if the thickness of the plastic forming the upper 12 is 0.30 mm, the upper 12 needs to have the highest rigidity by adopting a design in which the mouth 15 is arranged near the knee (for example, 1 cm below the knee). Even under the condition, it has been confirmed that the upper 12 as a whole can reliably keep the shape rising from the shoe sole 11.

Therefore, in terms of maintaining the shape of the entire upper 12 rising from the shoe sole 11, there is no advantage even if the plastic forming the upper 12 is thicker than 0.30 mm, and conversely, it is necessary to form the upper 12. There is a problem that the cost increases due to an increase in raw materials.
Therefore, in the present embodiment, the thickness of the plastic forming the upper 12 is 0.05 mm or more and 0.30 mm or less.
Furthermore, the thickness of the plastic forming the upper 12 is set to 0.05 mm or more, so that the foot cover 10 has a robust appearance, and the foot cover is not concerned with the eyes compared to the foot cover that is not robust. 10 can be attached to go out. Therefore, it is also effective from the viewpoint of appearance that the thickness of the plastic forming the upper 12 is 0.05 mm or more.

Further, when the toe side of the foot 14 to which the foot cover 10 is attached is the front side and the heel side is the rear side, a height region from the position where the ankle of the foot 14 of the upper 12 is arranged to the mouth 15 (hereinafter, “ As shown in FIGS. 1 to 3, a folding portion 16 is provided on the front side in the height region H ”.
The folding portion 16 is formed by folding the plastic sheet forming the upper 12 at a plurality of locations, and is provided from the top to the bottom of the height region H.
By widening the folding part 16 to the left and right, the height region H of the upper 12 becomes wide so that the foot 14 can be easily inserted into the foot cover 10 or the foot 14 can be easily removed from the foot cover 10. It comes out.

In the height region H of the upper 12, a plurality of through holes 17 are formed at or near the folding portion 16, and shoelaces 18 are attached to the plurality of through holes 17.
The height region H of the upper 12 is narrowed by tightening the shoelace 18 so that the adhesion to the foot 14 is enhanced. Therefore, the foot cover 10 can be securely fixed to the foot 14 by tightening the shoelace 18.

Further, the upper 12 is mainly formed from a cover body 19 that covers the toes and the instep of the foot 14, and a cover body 20 that is formed with a folding portion 16 and a mouth 15 and covers at least the heel and ankle of the foot 14. .
The cover bodies 19 and 20 are each formed of a single plastic sheet, and the cover body 19 is connected to the cover body 20.
