Description

The present invention is a foot cover that hides inside shoes such as sneakers (so-called athletic shoes regardless of gender) and pumps (mainly women's shoes with a wide open instep) when worn. In particular, the present invention relates to a foot cover that is easy to wear and comfortable to wear, and is less likely to come off or shift in position due to movements such as walking.

Wearing shoes such as pumps on bare feet has become a well-established fashion. In this case, if the pumps and the sole of the foot are in direct contact with each other, the sweat generated on the foot causes the inside of the shoe to become stuffy, which causes discomfort.
Therefore, we propose a thin foot cover that covers the toes and the sole including the heel and exposes the instep and ankle, and the opening is greatly cut so that it will not be exposed from the pumps when worn. Has been done. If you wear this foot cover and put on pumps, it looks like you are wearing pumps on your bare feet, and because the foot cover is between the sole and the pumps, sweat makes the inside of your shoes stuffy. It is possible to prevent it from happening.

In addition, although such a foot attachment is described as a foot cover in this specification, it may be described as a sock cover, an inner sock, a nude sock, a cover sock, or the like.
Since such a foot cover has a large cut so that it is not exposed from the pumps, the wearing position may shift or come off due to friction during walking or the like. On the other hand, if the opening is made smaller, it will be exposed from the pumps. A foot cover developed in view of such a problem is disclosed in the following prior art documents.

Japanese Patent Application Laid-Open No. 10-292206 (Patent Document 1) states that the foot cover may come off from bare feet due to friction between the pumps and the foot cover during walking, or the foot cover may come off when the pumps are put on or taken off. In order to prevent the foot cover from being displaced, a foot cover having a friction imparting body attached to the inner surface of the heel contact portion is disclosed.
In Practical New Design Registration No. 3165733 (Patent Document 2), if a rubber cord is provided along the peripheral edge of the opening of the foot cover disclosed in Patent Document 1, the rubber cord bites into the foot, so that the foot is made of rubber. In view of the problems that the string is attached, it feels painful, and it is not comfortable to wear, a flat rubber is provided along the periphery of the opening so that one side is in contact with the foot. The foot cover in which the portion is formed is disclosed.

Further, in the conventional foot covers disclosed in Patent Documents 1 and 2, the sole and the heel are made of separate knitted fabrics, and the knitted fabrics are sewn, so that the seams are the soles of the feet. Or it may get caught in the heel, and there is a problem that the foot cover may come off or the wearing position may shift when walking or taking off the pumps, or it may be difficult or uncomfortable to wear due to the seams. .. A foot cover that solves this problem is disclosed in Japanese Patent Application Laid-Open No. 2017-014669 (Patent Document 3). This foot cover is a foot cover that covers the toes and the sole including the ankle and exposes the instep and ankle, and is formed of the sole, the side surface, the ankle, and the toe portion that covers the toe. The sole, the side, the heel, and the toe are formed into a three-dimensional shape without seams by joining flat elastic knitted fabrics with adhesive tape. And.

Japanese Unexamined Patent Publication No. 10-292206 Utility Model Registration No. 3165733 JP-A-2017-014669

Here, the friction-imparting body of the foot cover disclosed in Patent Document 1 may not be sufficient. In this case, the foot cover may come off or the wearing position may be displaced when walking or taking off and putting on the pumps. Relax. In the flat rubber disclosed in Patent Document 2, since the flat rubber is provided over the entire peripheral edge of the opening (depending on the elasticity of the flat rubber), the opening is sufficiently opened when the foot cover is worn. In addition to the fact that it may be difficult to put on without opening, there is also a problem that the foot cover may come off or the wearing position may shift when the pumps are put on and taken off, as in the case of the foot cover disclosed in Patent Document 1.

Further, in the foot cover disclosed in Patent Document 3, since the sole and the heel are made of one knitted fabric, there is no seam for joining the sole and the heel, so that the foot cover is removed. Although it has been able to adequately solve the problems of looseness, misalignment, difficulty in wearing, and uncomfortable wearing, there is a possibility that it lacks three-dimensionality and design due to the single knitted fabric composition. In some cases, it may not be possible to completely eliminate the possibility that the foot cover may come off or the position of the foot may shift when putting on and taking off the shoes.

The present invention has been developed in view of the above-mentioned problems of the prior art, and an object of the present invention is that the foot cover may come off or the wearing position may shift when walking or putting on and taking off. The purpose is to provide a foot cover that is comfortable to wear and has sufficient three-dimensionality and design.

In order to achieve the above object, the foot cover according to the present invention takes the following technical measures.
That is, the foot cover according to the present invention is a foot cover that covers the toe and the sole including the foot and exposes the ankle, and is a toe that covers the sole, the lateral side, the heel, and the toe on the instep side. A first elastic knitted fabric and a second elastic knitted fabric are joined to the foot cover, which is formed of the portions and is provided with an opening for putting the foot in and out on the opposite side of the sole portion. The first elastic knitted fabric constitutes an upper side side portion, the toe portion, and an opening on the toe side, and the second elastic knitted fabric is on the lower side. It is characterized in that it constitutes a side side portion of the foot, the sole portion, the heel portion, and an opening on the heel side.

Preferably, the first elastic knitted fabric and the second elastic knitted fabric are elastic knitted fabrics without overlapping the first elastic knitted fabric and the second elastic knitted fabric. By abutting the peripheral edges of the above and joining them with an adhesive tape straddling the butted portions, it can be configured to be formed in a three-dimensional shape without any seams.
More preferably, the first elastic knitted fabric and the second elastic knitted fabric are flat knitted fabrics having predetermined peripheral shapes, respectively, and the peripheral edges of the first elastic knitted fabric. At least a part of the above and at least a part of the peripheral edge of the second elastic knitted fabric are butted against each other without overlapping the peripheral edges, and the first elastic knitted fabric is provided with an adhesive tape straddling the abutted portion. And the second elastic knitted fabric are joined to form the sole portion, the side side portion and the toe portion, and the peripheral edges of a part of the second elastic knitted fabric are overlapped with each other. The heel portion can be formed by joining the second elastic knitted fabric with an adhesive tape straddling the butted portions.

According to the foot cover of the present invention, the foot cover does not come off or the wearing position does not shift when walking or taking off, and it is comfortable to wear and has sufficient three-dimensionality and design. can.

It is an overall perspective view of the foot cover which concerns on embodiment of this invention. It is the whole perspective view which turned over the foot cover of FIG. It is a three-view view of the foot cover shown in FIG. It is a three-view view of the foot cover shown in FIG. It is a development view of the foot cover of FIG.

Hereinafter, the foot cover 100 according to the embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is an overall perspective view showing a wearing state in which the foot cover 100 according to the present embodiment is worn on the foot F, and FIG. 2 is an overall perspective view showing the foot cover 100 shown in FIG. 1 turned inside out. The three views of the wearing state shown in FIGS. 1 and 2 are FIG. 3 (a view corresponding to FIG. 1) and FIG. 4 (a view corresponding to FIG. 2 and the view obtained by turning over FIG. 3). Further, FIG. 5 is a development view of the foot cover 100, and is a pattern of the elastic knitted fabric constituting the foot cover 100 (the first pattern 140 and the second pattern 140 for the first elastic knitted fabric 104). It is also the figure which shows the 2nd pattern 120) for elastic knitted fabric 102. Here, FIGS. 1 to 4 assume a state in which the foot cover 100 is worn on the wearer's foot F. That is, since the foot cover 100 according to the present embodiment is formed of a thin elastic knitted fabric used for pantyhose or the like, if it is not shown in this assumption, it will be in a shrunk state and have a shape. Since it is difficult to understand, it is assumed as described above. In particular, in FIGS. 3 and 4, the sole 102B is drawn so as to be clearly visible compared to the state in which the foot cover 100 is actually worn so that the features of the foot cover 100 can be easily understood.

Hereinafter, the foot cover 100 will be described in detail based on these figures. Here, there are various structures of the foot cover, and the present invention is not limited to a specific structure, and any structure of the foot cover can be used as long as it has the features described later. However, basically, it does not matter what kind of fabric constitutes the foot cover, the pattern of the fabric, and the method of joining the fabric. In the foot cover 100, a knitted fabric is used as the fabric. The foot cover structure itself shown below is merely an example.

The fabric forming the foot cover 100 is knitted using a yarn (covered yarn, etc.) wound with a yarn of another material (cotton, wool, etc.) around a bare heaven (bare heaven: polyurethane yarn). Flat knitted fabric), tricot (warp knitted fabric knitted by a tricot machine which is a kind of warp knitting machine), fabric for pantyhose (knitted fabric containing polyurethane yarn and nylon yarn) and the like are preferably used. In particular, among these, bare heaven has (1) excellent elasticity, (2) good shape stability and little shape change after washing, and (3) soft texture and excellent fit. , (4) It is hard to wrinkle and crease, (5) It has a porous structure, so it is breathable, and (6) When it contains cotton, it has good touch and hygroscopicity, which is preferable for a foot cover.

Further, the foot cover 100 according to the present embodiment covers the toes and the sole including the heel and exposes the ankle. Here, when the foot cover 100 is worn, the instep may or may not be exposed, but the foot cover 100 is worn and the pumps (mainly the instep part, which is the opening of the foot, is wide open). When wearing women's shoes), it is preferable that the instep is exposed and the foot cover 100 is hidden by the pumps. The foot cover 100 includes a sole portion 102B, a side side portion 108 (more specifically, an upper side side portion 104B and a lower side side portion 102A), a heel portion 102C, and a toe portion 104A covering the toe on the instep side. It is formed and is provided with an opening 106 (more specifically, an opening 106A on the toe side and an opening 106B on the heel side) for moving the foot F in and out on the opposite sides of the sole 102B.

Further, although not limited, the foot cover 100 shown below is shared on the left and right sides, and is preferable in that the left and right sides are not mistakenly worn because the foot cover 100 is shared on the left and right sides. If the foot cover is not shared on the left and right sides, the left foot cover and the right foot cover have symmetrical shapes. If you wear this foot cover 100 on your foot F and wear shoes such as sneakers (so-called athletic shoes regardless of gender) or pumps (mainly women's shoes with the instep part that is the opening wide open), Since the foot cover 100 is hidden inside the shoes and the foot cover 100 is not exposed from the shoes, the foot cover 100 cannot be seen. Here, the fact that the foot cover 100 is not exposed from the shoes when worn includes the fact that the foot cover 100 is hidden by the shoes and becomes invisible or difficult to see.

And, characteristically, this foot cover 100 has a first elastic knitted fabric 104 (a knitted fabric having the same peripheral shape as the first pattern 140 shown in FIG. 5) and a second elastic knitted fabric 104. It is formed by joining the knitted fabric 102 (a knitted fabric having the same peripheral shape as the second pattern 120 shown in FIG. 5). The first elastic knitted fabric 104 includes an upper side side portion 104B, a toe portion 104A (which covers the toe on the instep side and does not cover the toe on the sole side), and an opening 106A on the toe side (hereinafter,). In some cases, it may be described as the toe side opening 106A). The second elastic knitted fabric 102 includes a lower side side portion 102A, a sole portion 102B, a heel portion 102C, and a heel side opening 106B (hereinafter, may be referred to as a heel side opening 106B). And configure.

Here, regarding the opening 106, the foot cover 100 has a small opening area because it is for deep wearing (suitable for sneakers), and the upper side side portion 104B covers the instep. However, the foot cover according to the present invention having the above-mentioned features is not limited to such deep wearing. For example, by changing the toe side opening 106A to the toe side enlarged opening 156A as shown by the two-dot chain line in FIG. 5, the first elastic knitted fabric 104 is used (shown by the two-dot chain line arrow in FIG. 5). As described above, the toe side opening 106A can be expanded to the enlarged opening 156A in the drawing), and the opening 106 can be expanded to the front side (toe side) to the position shown by the alternate long and short dash line in FIG. By changing the first elastic knitted fabric 104 in this way, it is possible to realize a foot cover 100 for shallow wear (which can be hidden even when wearing pumps) while maintaining the features of the present invention. In this case, the upper side side portion 104B constitutes the side side portion 108 that does not cover the instep but only covers the side of the foot.

In the foot cover 100, as shown below, the first elastic knitted fabric 104 and the second elastic knitted fabric 102 are provided with adhesive tape 110 on the surface opposite to the skin contact surface (outside: shoe side). However, the present invention is not limited to this. It is not limited as long as it joins the first elastic knitted fabric 104 and the second elastic knitted fabric 102, and may be joined (sewn) by, for example, sewing (adhesion by suturing). No. Further, even when joining with the adhesive tape 110, the skin contact surface (inside: skin side) may be joined with the adhesive tape 110 instead of the surface opposite to the skin contact surface, and the skin contact surface and its surface may be joined. Both sides of the opposite surface may be joined with adhesive tape 110. As described above, the joining of the knitted fabric is not limited, but when the adhesive tape is adopted, the adhesive is applied to one surface of the strip-shaped member, and the adhesive is heated by heating. It is preferable that the knitted fabric is melted and the knitted fabric is heat-bonded and joined. The joining in this case includes those by thermocompression bonding, those by heat welding, those by heat welding, and the like. In general, such an adhesive tape 110 has a smaller elasticity than the first elastic knitted fabric 104 and the second elastic knitted fabric 102 and is hard to stretch, and is sutured when it is sewn instead of the adhesive tape. The portion is less elastic and less stretchable than the first elastic knitted fabric 104 and the second elastic knitted fabric 102.

Then, preferably, when the foot cover 100 is joined by the adhesive tape 110, the first elastic knitted fabric 104 and the second elastic knitted fabric 102 are combined with the first elastic knitted fabric 104 and the second elastic knitted fabric 102. The edges of the stretchable knitted fabric are butted against each other without overlapping with the stretchable knitted fabric 102, and are joined by an adhesive tape 110 straddling the butted portions to form a three-dimensional shape without seams. .. For this reason, the foot cover 100 has no steps because the peripheral edges are butted against each other, and since the adhesive tape is used as the joining method, the foot cover 100 is formed in a three-dimensional shape without any seams.
More preferably, the first elastic knitted fabric 104 and the second elastic knitted fabric 102 have a predetermined peripheral shape as shown in the first pattern 140 and the second pattern 120 of FIG. 5, respectively. It is a flat knitted fabric. At least a part of the peripheral edge of the first elastic knitted fabric 104 (here, the upper adhesive line 110U having a U-shaped peripheral edge shape shown in FIG. 5) and at least a part of the peripheral edge of the second elastic knitted fabric 102. (Here, the lower adhesive line 110D having an inverted U-shaped peripheral edge shape shown in FIG. 5) is abutted against each other without overlapping the peripheral edges, and the first elastic knitted fabric is provided with the adhesive tape 110 straddling the abutted portion. By joining the 104 and the second elastic knitted fabric 102, the sole portion 102B, the side side portion 108 (upper side side portion 104B and the lower side side portion 102A), and the toe portion 104A are formed. There is. Further, a part of the peripheral edges of the second elastic knitted fabric 102 (here, the right side adhesive line 112R and the left side adhesive line 112L shown in FIG. 5) are butted against each other without overlapping, and the heel adhesive tape straddling the butted portion. The heel portion 102C is formed by joining the second elastic knitted fabric 102 with 112.

As described above, in the foot cover 100, the first elastic knitted fabric 104 and the second elastic knitted fabric 102 are joined to each other by abutting at least a part of the peripheral edges thereof with the adhesive tape 110, and the second elastic knitted fabric 102 is joined. By abutting some of the peripheral edges of the elastic knitted fabric 102 and joining them with the heel adhesive tape 112, there is no step because the peripheral edges are butted together, and since the adhesive tape is used as the joining method, no seams are provided. , It is formed in a three-dimensional shape.

The details of the foot cover 100 having such a feature will be described in more detail.
As described above, the stretchable narrow cloth 114 is provided over the entire circumference of the upper edge of the opening 106 provided for putting the foot in and out on the opposite side of the sole 102B. In this foot cover 100, the stretchable narrow cloth 114 is folded back and folded back (for example, as described in Japanese Patent Application Laid-Open No. 2014-133952 filed and published by the applicant of the present application), but not limited to this. The vertical line is provided so as to substantially coincide with the upper edge of the opening 106. As a result, approximately half of the width of the elastic narrow fabric 114 is on the inside of the foot cover 100 (inside where the foot F is in contact: the skin contact surface side), and the other side of the width of the elastic narrow fabric 114. A stretchable narrow cloth 114 is provided straddling the outer side of the foot cover 100 (the outer side on the opposite side where the foot F contacts: the opposite surface of the skin contact surface). When the foot cover 100 is worn, if the stretchable narrow fabric 114 is stretched, the opening is wide open, so that it is easy to wear, and after wearing the foot cover 100, the stretchable narrow fabric 114 is contracted to open. Since the portion is small, the foot cover 100 does not come off during walking. It should be noted that, over the entire circumference of the upper edge of this opening, only the outside of the foot cover 100 (the side opposite to the side where the foot F contacts: the outside: the shoe side) or only the inside (the side where the foot F contacts: the inside: the skin side). ) May be provided with the elastic narrow cloth 114. The stretchable narrow cloth 114 may be provided not on the entire circumference of the upper edge of the opening but on a part of the upper edge, or may be provided intermittently instead of continuously.

Further, on the inside of the foot cover 100 (the side in contact with the foot F: the skin side) at the upper edge of the heel portion 102C of the foot cover 100, a heel non-slip 116 formed of a thin transparent sheet such as silicone resin is provided. It is also preferable to provide it. Therefore, in the heel portion 102C, the second elastic knitted fabrics 102 are joined to each other by the heel adhesive tape 112 (here, the heel adhesive tape 112 is adhered only to the outside (shoe side) and the inside (skin side) is the second. The edges of the elastic knitted fabric 102 are only butted against each other), the elastic narrow fabric 114 is provided on the inside (skin side), and the heel non-slip 116 is provided on the inside (skin side). There is. As a result, it is possible to improve the adhesion of the foot F to the heel and further prevent the foot cover 100 from being displaced from the heel portion of the foot F. The heel non-slip 116 is not an essential configuration for the foot cover according to the present invention.

As shown in the developed view (pattern) of FIG. 5, the features of the foot cover 100 are the upper side side portion 104B and the toe portion 104A (covering the toe on the instep side and not covering the toe on the sole side). And the toe side opening 106A are composed of a first elastic knitted fabric 104 having a predetermined peripheral shape represented by the first pattern 140, and the lower side side portion 102A, the sole portion 102B, and the heel portion. The point is that the 102C and the heel side opening 106B are formed of a second elastic knitted fabric 102 having a predetermined peripheral shape represented by the second pattern 120. That is, the side side portion 108 is composed of an upper side side portion 104B and a lower side side portion 102A. In this way, the side side portion 108 is formed by joining two elastic knitted fabrics to the upper side side portion 104B and the lower side side portion 102A, and the joining line is directed from the toe to the heel. As long as the foot cover is raised diagonally, the number of elastic knitted fabrics may be three (or more) instead of two.

Then, the first elastic knitted fabric 104 and the second elastic knitted fabric 102 are brought close to each other in the direction of arrow X (1) and the direction of arrow X (2) in FIG. 5, respectively, and the first elasticity is obtained. The upper adhesive line 110U, which is the peripheral edge of the knitted fabric 104 other than the toe side opening 106A, and the lower side other than the heel side opening 106B, the right adhesive line 112R, and the left adhesive line 112L of the second elastic knitted fabric 102. The adhesive wire 110D is abutted against each other so that the knitted fabrics do not overlap each other, and the peripheral edges thereof are brought into contact with each other and joined by one adhesive tape 110. The adhesive tape 110 may be divided into two or more instead of one.

That is, at least a part of the peripheral edge of the first elastic knitted fabric 104 (upper adhesive line 110U shown in FIG. 5) and at least a part of the peripheral edge of the second elastic knitted fabric 102 (lower adhesive line shown in FIG. 5). 11
0D) is abutted against each other without overlapping the peripheral edges, and the first elastic knitted fabric 104 and the second elastic knitted fabric 102 are joined by an adhesive tape 110 straddling the abutted portion to form a sole portion. 102B, side side portion 108 (upper side side portion 104B and lower side side portion 102A) and toe portion 104A are formed.

Further, the right side adhesive line 112R and the left side adhesive line 112L in the second elastic knitted fabric 102 are butted against each other so that the knitted fabrics do not overlap each other, and their peripheral edges are brought into contact with each other so that the one heel adhesive tape 112 It is joined by. The heel adhesive tape 112 may be divided into two or more instead of one.
That is, a part of the peripheral edges of the second elastic knitted fabric 102 (right side adhesive line 112R and left side adhesive line 112L shown in FIG. 5) are butted against each other without overlapping, and the heel adhesive tape 112 straddling the butted portion is used. The heel portion 102C is formed by joining the second elastic knitted fabric 102.

In these cases, the adhesive tape 110 and the heel adhesive tape 112 are coated with an adhesive on one surface (the side of the knitted fabric (first elastic knitted fabric 104 and the second elastic knitted fabric 102)) and are heated. By doing so, the adhesive applied to the adhesive tape 110 and the heel adhesive tape 112 is melted and the knitted fabric is heat-bonded and joined. Further, in the foot cover 100, the adhesive tape 110 and the heel adhesive tape 112 are heat-bonded from the front side of the foot cover 100 (the opposite side where the foot F contacts: the shoe side) to join the knitted fabric. However, as described above, the adhesive tape 110 and / or the heel adhesive tape 112 may be heat-bonded from the back side of the foot cover 100 (the side where the foot F contacts: the skin side) to join the knitted fabric. .. In this way, since the peripheral edges are butted against each other, there is no step, and since the adhesive tape is adopted as the joining method, no seams are provided, and the sole portion 102B and the side side portion 108 (upper side side portion 104B and lower side). Side side portion 102A), heel portion 102C, and toe portion 104A covering the toe on the instep side, and an opening 106 (toe side opening) for moving the foot F in and out on the opposite side to the sole 102B. The foot cover 100 provided with the 106A and the heel side opening 106B) is three-dimensionally formed.

In this three-dimensionally formed foot cover 100, the seams that occur when the sole and the heel are sewn with different knitted fabrics as in the conventional foot cover are caught on the heel and walk. It is possible to avoid the problem that the foot cover comes off or the wearing position shifts when putting on and taking off the pumps, and since there are no steps or seams, the comfort is extremely good.

As described above, the side side portion 108 of the foot cover 100 has an upper side side portion 104B (first elastic knitted fabric 104) and a lower side side portion 102A (second elastic knitted fabric 102). It is composed of. Then, the first elastic knitted fabric 104 and the second elastic knitted fabric 102 are joined to form the side side portion 108 of the foot cover 100. Therefore, the joining lines (upper adhesive line 110U and lower adhesive line 110D) between the first elastic knitted fabric 104 and the second elastic knitted fabric 102 are shown by white arrows in FIGS. 1 to 4. It rises diagonally from the tip of the toe to the heel. The adhesive tape 110 or the sewn portion provided along the joint line is (usually) less stretchable than the first elastic knitted fabric 104 and the second elastic knitted fabric 102 (usually). (Because it is less elastic and harder to stretch than the stretchable knitted fabric), the pulling force indicated by the white arrow is exhibited. Therefore, when the foot cover 100 is worn and the shoes are worn and the person walks, even if the foot cover 100 is pulled down in the direction in which the foot cover 100 is removed (diagonally downward) according to the movement of the shoes, the pulling force thereof. It is possible to prevent the foot cover 100 from being displaced from the foot F by the pulling force indicated by the white arrow that opposes the above.

Although not limited, it is also preferable that the foot cover 100 is provided with a suspension holding portion 130 that wraps around the instep portion of the wearer when worn to prevent the foot cover 100 from shifting. The suspension hold portion 130 is provided with, for example, a fabric having a smaller elasticity and less stretch than the first elastic knitted fabric 104 and / or the second elastic knitted fabric 102 around the instep portion. It will be realized. More specifically, a fabric having a small elasticity forming the suspension hold portion 130 on the instep portion of the side side portion 108 composed of the lower side side portion 102A and the upper side side portion 104B. Is pasted. In this case, in the foot cover 100, the fabric having low elasticity constituting the suspension hold portion 130 is attached to the inside (skin side) of the side side portion 108, but the outside of the side side portion 108 (shoes). It may be attached to the side), or may be attached to the inside (skin side) and the outside (shoe side) of the side side portion 108. Further, the suspension holding portion 130 may be divided into a lower portion corresponding to the lower side side portion 102A and an upper portion corresponding to the upper side side portion 104B.

Further, but not limited to, the foot cover 100 is provided with a toe hygroscopic portion 132 that wraps around the toe portion of the wearer when worn and absorbs sweat generated when the foot cover 100 is worn. Is also preferable. The toe moisture absorbing portion 132 is provided with, for example, a fabric having a higher hygroscopicity than the first elastic knitted fabric 104 and / or the second elastic knitted fabric 102 and easily absorbing sweat, around the toe portion. It will be realized. More specifically, the highly hygroscopic fabric constituting the toe moisture absorbing portion 132 is formed on the toe portion composed of the lower sole portion 102B and the upper side (covering the instep side toe tip) toe portion 104A. Is pasted. In this case, a highly hygroscopic fabric constituting the toe hygroscopic portion 132 is attached to the inside (skin side) of the foot cover 100. Even if the toe moisture absorbing portion 132 is divided into a lower portion corresponding to the lower sole portion 102B and an upper portion corresponding to the upper toe portion 104A, either the upper side or the lower side is provided. Only one side may be used. Further, such a moisture absorbing portion may be provided on the entire skin side of the sole portion 102B.

Further, in the sole portion 102B, the sole portion formed of a thin sheet such as silicone resin is formed on the side opposite to the side in contact with the foot F (the side in contact with the inner sole of the pump when wearing the pump, which is an example of shoes). It is also preferable to provide a non-slip. As a result, it is possible to improve the adhesion with the inner bottom of the pump and prevent the position of the foot cover 100 in the pump from being displaced. It should be noted that this non-slip sole is also not an essential configuration for the foot cover according to the present invention.

In the foot cover 100, the first elastic knitted fabric 104 and the second elastic knitted fabric 102 and the elastic narrow fabric 114 forming the foot cover 100 are formed of the same co-fabric. It doesn't matter. That is, except for the adhesive tape 110 and the heel adhesive tape 112, the foot cover 100 may be all made of the same elastic knitted fabric (tricot or the like). In the foot cover 100, the stretchable narrow fabric 114 is a stretchable knitted fabric in which the adhesive applied to the stretchable narrow fabric 114 is melted by heating the stretchable knitted fabric with a heat press device. It is heat-bonded and joined.

Further, in the foot cover 100, the first elastic knitted fabric 104 and the second elastic knitted fabric 102 forming the foot cover 100 may be formed instead of the same fabric, and the first elastic knitted fabric 102 may be formed. The knitted fabric 104, the second elastic knitted fabric 102, and the elastic narrow fabric 114 may be formed instead of the same fabric.
As described above, according to the foot cover 100 according to the present embodiment, the first elastic knitted fabric 104 and the second elastic knitted fabric 102 are each composed of one knitted fabric, and they are used. Is joined by the adhesive tape 110, and the heel portion 102C joined by the heel adhesive tape 112 is formed, so that the sole portion 102B and the side side portion 108 (upper side side portion 104B and lower side side portion) are formed. 102A), an opening 106 (toe side opening 106A and toe side) formed of a toe portion 102C and a toe portion 104A covering the toe on the instep side, and for moving the foot F in and out on the opposite side to the sole portion 102B. The foot cover 100 provided with the opening 106B) is three-dimensionally formed. For this reason, the foot cover is a problem that occurs when the sole and heel are sewn with different knitted fabrics as in the conventional foot cover. It is possible to avoid the problem that the heel is taken off or the wearing position is displaced. Further, according to the foot cover 100, since there are no steps or seams, the foot cover 100 is extremely comfortable to wear.

Further, the joint lines (upper adhesive line 110U and lower adhesive line 110D) between the first elastic knitted fabric 104 and the second elastic knitted fabric 102 are obliquely raised from the toes toward the heel, and Since the adhesive tape 110 provided along the joint line is (usually) less stretchable and less stretchable than the stretchable knitted fabric, a pulling force is exerted. Therefore, when the foot cover 100 is worn and the shoes are worn and the person walks, even if the foot cover 100 is pulled down in the direction in which the foot cover 100 is removed (diagonally downward) according to the movement of the shoes, the pulling force thereof. It is possible to prevent the foot cover 100 from being displaced from the foot F by the pulling force indicated by the white arrow that opposes the above.

It should be noted that the embodiments disclosed this time are exemplary in all respects and are not considered to be restrictive. The scope of the present invention is shown by the scope of claims rather than the above description, and it is intended to include all modifications within the meaning and scope equivalent to the scope of claims.

The present invention is suitable for a foot cover worn with bare feet, and the foot cover does not come off or the wearing position does not shift when walking or taking off, and it is comfortable to wear, and has sufficient three-dimensionality and design. It is particularly preferable in that it has sex.
