Description

  The present invention relates to a heel-less foot cover which does not come off when a wearer walks, moderately reduces impact on a foot, and has a heat retaining effect.

  A normal foot cover is entirely a thin knitted fabric, and is a type of sock that mainly covers a toe and a heel. This foot cover is also called inner socks, cover socks, socks cover.Women and young people prefer to wear pumps and sneakers with bare feet as a fashion, and when wearing bare feet, the wearer's feet and soles directly It is common to wear a foot cover in advance to reduce discomfort caused by contact.

  When wearing a normal foot cover, only the soles, toes, both sides and heels are covered, and unlike socks, most of the insteps and ankles are exposed. Part of the cover is not visible from the outside. This makes it look like you are wearing pumps and sneakers directly on your bare feet, and is suitable for young people's fashion. Even if a normal foot cover has a non-slip portion inside the heel portion, the upper opening of the wearing mouth is largely cut, so that the foot cover may be detached from the foot during walking and the wearing position of the cover. Often shifts.

  Therefore, many inventions and ideas have been proposed in order to improve the problem that several foot covers are easily detached during walking. For example, in Japanese Utility Model Laid-Open No. 6-51207 and JP-A-9-59804, a friction imparting member is attached to the inner surface of the heel contact portion, and the friction imparting member is made of a sheet of rubber, urethane foam, silicone rubber, or the like. Body. Further, Japanese Patent Application Laid-Open No. 2005-66152 and Utility Model Registration No. 3172726 both are members that keep the toes warm of the wearer, and a flat rubber or a thin stopper is applied to the wearer's heel to prevent falling off, The former uses a titanium net formed by weaving a titanium wire in a net shape, and the latter uses a heat insulating material such as foamed resin particles in the inside of the toe bag portion and the sole bag portion.

Japanese Utility Model Publication No. 6-51207 JP-A-9-59804 JP 2005-66152 A Japanese Utility Model Registration No. 3172726

  In Japanese Utility Model Laid-Open No. 6-51207 and Japanese Patent Application Laid-Open No. 9-59804, in order to prevent the foot cover from slipping off or slipping out of position with only the friction applying member attached to the inner surface of the heel contact portion, the slipping out and slipping out of slipping position are actually prevented. Complete prevention is practically difficult. For this reason, when the elastic narrow cloth or the band-shaped silicone portion is provided on the heel part and the side part near the upper opening, the narrow cloth or the silicone tape has a certain width and thickness, so that The upper part is tightened more than necessary, and the comfort of the foot cover decreases.

  Japanese Patent Application Laid-Open No. 2005-66152 and Utility Model Registration No. 3172726 are foot covers that do not have a heel portion in appearance and are similar to the present invention, and a flat rubber or a thin stopper portion is directly hung on a heel portion of a wearer. Since the cover is prevented from falling off, it is unlikely that the cover slips off from the heel. However, Japanese Patent Application Laid-Open No. 2005-66152 uses a flat rubber different from the foot warmer, and Japanese Utility Model Registration No. 3172726 uses a stopper unit integrated with the sole bag part. There is almost no pull on the instep when a thin stopper is hung, which is not enough to provide comfort and prevent the foot cover from falling off.

  The present invention has been proposed in order to improve the above-mentioned problems with the existing foot cover, and it is less likely to come off when the wearer walks, etc., and the impact is moderately moderated, so that the comfort is good. It is intended to provide a certain heel-less foot cover. It is another object of the present invention to provide a heel-less foot cover that reliably prevents slippage during walking and has a heat retaining effect.

  The heel-less foot cover according to the present invention is knitted with an elastic knitted fabric and covers the toe portion and both side portions of the wearer's toe, and a sole portion having a length reaching the arch from the toe portion of the wearer. And a strip-shaped narrow portion extending from the rear of the instep portion. In the foot cover of the present invention, the sole of the foot has a three-layer structure in which a cushioning material having both heat insulation and impact resistance is interposed between the upper and lower fiber layers. When the width portion is locked to the upper part of the heel of the wearer, the instep portion is pulled rearward together with the band-shaped narrow width portion, thereby fixing the cover to the foot when worn.

  In the heel-pull foot cover according to the present invention, the instep portion and both narrow portions are entirely formed of an elongated knitted fabric, and the edges of both narrow portions are sewn together to form a band-like narrow portion, and then the upper opening is formed. In addition, it is preferable that the band-shaped narrow width portion is edge-stitched, and that the lower middle portion of the knitted fabric and the periphery of the sole are stitched together to form a bag-shaped instep portion. In addition, the sole of the foot is composed of a bare woven fabric of an upper fiber layer, a cushion material of a polyurethane sheet having a thickness of 3 to 7 mm, and a knitted fabric of a lower fiber layer. Integrate. Further, a resin non-slip portion having adhesiveness is formed in a predetermined range above the surface of the lower fiber layer in the sole portion, and it is preferable that each of the resin non-slip portions is made of a silicone resin.

  The foot cover covers the toe and both side portions of the wearer, and the instep portion and the band-shaped narrow portion are made of an integrated knitted fabric, so that the heel-less foot cover according to the present invention is thin and easily stretchable. The lower part of the instep tends to pull backwards through the part, protecting the wearer's foot side as well as taking off the instep during walking and not displacing the position, making it comfortable to wear for a long time Does not drop. In the heel-less foot cover of the present invention, the heel portion does not exist in the cover itself, only the rear narrow band portion is locked to the upper part of the heel portion of the wearer, so the heel portion of the foot cover falls off from the foot Is unlikely to occur.

  The foot cover according to the present invention has a three-layer structure in which the sole of the foot has a cushioning material interposed between the upper and lower fiber layers, and the cushioning material has a thickness having both heat insulation and shock resistance. When worn on the feet, the impact on the soles during walking is moderately moderated, so that the comfort is good and, moreover, it has a moderate heat retaining effect. Furthermore, by forming a resin non-slip in a predetermined range above the surface of the lower fiber layer in the sole, it prevents the foot cover from slipping on the floor or in shoes during walking, and maintains comfortable and safe comfort I do.

FIG. 2 is an overall plan view showing the heel-less foot cover according to the present invention, and the shape of the band-shaped narrow portion is not constant. It is a top view which shows the whole back surface of the foot cover of FIG. FIG. 2 is a side view showing a state where the foot cover of FIG. 1 is attached to a foot. It is a cross-sectional view which expands and shows the sole part of a foot cover. It is a schematic plan view showing the deployment state of the knitted fabric used for the instep of the foot cover. It is a schematic plan view of a knitted fabric showing a state before suturing the end sides of both narrow width portions.

  As shown in FIG. 3, the foot cover 1 without heels according to the present invention, as shown in FIG. 3, covers the toe part a of the wearer 2 and the instep part 3 that covers both side parts b, b, and from the toe part a of the wearer 2 to the arch c. It has a sole portion 5 of a length to be reached and a strip-shaped narrow portion 7 extending from the rear of the instep portion. When the wearer 2 wears the foot cover 1, the toe of the wearer 2 is fitted between the bag-shaped instep portion 3 and the sole portion 5, and then the belt-shaped narrow portion 7 is attached to the heel g of the wearer 2. When hooked near the upper Achilles tendon, most of the instep e and the ankle f of the wearer 2 are exposed, and the heel g is also exposed.

  The instep portion 3 and the strip-shaped narrow portion 7 of the foot cover 1 are formed by sewing a plurality of pieces of knitted fabric even if the whole is not integrally formed, even if it is an integrated elongated knitted fabric as illustrated in FIG. It is also possible to use partially woven pieces. The knitted fabric 10 shown in FIG. 5 is usually an elongated flat shape that is symmetrical about the center line A. For example, the upper side 12 is gently curved upward toward both ends, and the lower side 14 is on both sides from the central toe portion 16. The plane shape is such that it rises toward the side part 18 and then approaches flat, and then rises rapidly from the lower end 20 of the side parts 18 to the end sides 22 of the narrow parts 21 on both sides.

  On the other hand, as shown in FIG. 4, the sole 5 has a three-layer structure in which a cushion material 28 having both heat insulation and impact resistance is interposed between the upper and lower fiber layers 24 and 26. For example, the woven knitted fabric may be composed of a bare woven fabric of the upper fiber layer 24, a cushion material 28 of a polyurethane sheet having a thickness of 3 to 7 mm, and a knitted fabric of the lower fiber layer 26. This polyurethane sheet has a thickness of less than 3 mm, and the effects of heat retention and impact resistance are small. If the thickness is more than 7 mm, the polyurethane sheet easily collapses. As shown in FIG. 1, the sole 5 has a flat shape close to an elongated elliptical shape corresponding to a foot shape plane, and its vertical length reaches the middle of the arch c from the toe a of the wearer 2, and if desired. The length may cover the entire arch of the wearer 2.

  In the foot cover 1, the knitted fabric 10 is formed of one or more fiber yarns such as cotton yarn, polyester fiber, acetate fiber, nylon fiber, acrylic fiber, polyurethane fiber, and a blended fiber of cotton yarn and polyester fiber, and the whole is a thin integrated yarn. A knitted fabric has high elasticity, and a coated elastic yarn obtained by covering a core yarn of a polyurethane yarn with a thin polyester fiber or nylon can be used, and these may be used for the fiber layers 24 and 26. For example, the knitted fabric 10 and / or the fiber layers 24 and 26 are made of a knitted fabric having elasticity such as a mixed material of nylon and polyurethane.

  In the sole portion 5, as shown in FIG. 2, a resin non-slip portion 32 having adhesiveness is formed in a predetermined range above the surface of the lower fiber layer 26 (see FIGS. 3 and 4). The resin non-slip portion 32 may disperse and arrange a plurality of point-like spots as shown in the figure or intermittently arrange elongated rectangular or linear spots. The resin non-slip portion 32 is preferable because the resin 2 does not slip when the wearer 2 wearing the foot cover 1 comes into contact with the floor when walking on the floor, and the foot cover does not slip in the shoe.

  The resin non-slip portion 32 is made of silicone resin or other adhesive resin, and is fed to a rotary or fan screen printing machine to perform thick printing, or a thick printing by silk screen machine, printing by letterpress or intaglio printing machine, It may be formed by heat fusion of a tape material. It is preferable that there is no point where the plane is sharp at the resin non-slip portion 32 because it is less likely to peel off from that point.

  When the knitted fabric 10 shown in FIG. 5 is used in the foot cover 1, the knitted fabric is bent as shown in FIG. 6, and the end sides 22, 22 of both narrow width portions 21 are sewn to form the band-like narrow width portion 7. After that, the lower edge 20 of the upper side 12 corresponding to the upper opening 30 (FIG. 3) and the lower side 20 corresponding to the lower side of the strip-shaped narrow portion 7 are sewn. The edge stitching is double chain stitching using one to four stretchable threads, edge over stitching, or the like. On the other hand, it is preferable that the upper sole layer 5, the cushion material 28, and the lower fiber layer 26 be overlapped and temporarily sewn around the sole 5. Next, an intermediate portion of the lower side 14 of the knitted fabric 10, that is, the toe portion 16 and both side portions 18 and the periphery of the sole portion 10 are sewn together by the rim seam 29, thereby forming the bag-shaped instep portion 3, As a result, the foot cover 1 having the strip-shaped narrow portion 7 at the rear is obtained.

  When the heel-pull foot cover 1 is worn in FIG. 3, the band-shaped narrow width part 7 is hooked near the Achilles tendon above the heel part g of the wearer 2, and the toe part a and the both side parts b of the wearer 2 are mainly used. Thus, the heel g is completely exposed, and the majority of the instep e, the rear half of the sole, and the ankle f are exposed. The foot cover 1 has a large upper opening 30 as a wearing mouth so as not to be exposed from shoes such as pumps and sneakers when worn. The upper opening 30 and the strip-shaped narrow portion 7 are prevented from being frayed by edge stitching with an elastic thread. Even if the upper opening has a high elasticity, it does not spread due to continued use.

  As shown in FIG. 2, the foot cover 3 of the heel-pull foot cover 1 tends to be pulled backward through the band-shaped narrow portion 7, so that the bag-shaped footstep 3 may come off when the wearer 2 walks. There is no displacement. Since the foot cover 1 merely locks the rear narrow band portion 7 on the upper part of the heel of the wearer 2 and has no heel on the cover itself, a situation in which the heel of the foot cover falls off from the foot occurs. can not help it.

  The heel-less foot cover 1 has a three-layer structure in which the sole 5 has a cushion material interposed between the upper and lower fiber layers 24 and 26. The cushion material has a thickness of 3 to 7 mm which has both heat insulation and shock resistance. Have. For this reason, when the foot cover 1 is worn on the feet of the wearer 2, the impact is moderately reduced during walking, so that the comfort is good and the heat retaining effect is appropriate.

  Furthermore, in the foot cover 1, by forming the resin non-slip portion 32 in a predetermined range above the surface of the lower fiber layer 26 of the sole 5, when the foot cover 1 is worn, the wearer 2 can Does not slip when it comes into contact with the floor surface during walking, and when shoes are worn, the foot cover 1 does not shift in the shoes, so that comfortable and safe wearing can be maintained.

  Next, the present invention will be described based on embodiments, but the present invention is not limited to the embodiments. As shown in FIG. 5, the instep portion 3 and the band-shaped narrow portion 7 of the foot cover 1 are formed of an integral elongated knitted fabric 10 which is a mixed material of nylon and polyurethane. The knitted fabric 10 which is a flat knitted fabric has a plane shape which is symmetrical about the center line, the upper side 12 is gently curved upward toward both ends, and the lower side 14 is directed from the center toe portion 16 to both side portions 18. After being temporarily raised, the flat shape approaches a flat surface, and further rises sharply from the lower end 20 of the both sides 18 to the ends 22 of the narrow portions 21 on both sides.

  On the other hand, the sole 5 is composed of a bare fabric of the upper fiber layer 24, a cushion material 28 of a polyurethane sheet having a thickness of 5 mm, and a knitted fabric of the lower fiber layer 26. As shown in FIGS. 1 and 2, the sole 5 has a flat shape close to an elongated elliptical shape corresponding to a foot shape plane, and its vertical length reaches the middle of the arch from the toe of the wearer 2. Since the bare fabric is soft to the touch, it is suitable as the upper fiber layer 24 of the sole 5.

  The lower fiber layer 26 of the sole 5 is fed in advance to a rotary or fan-type screen printing machine, and a resin non-slip portion 32 is thickly printed on the upper surface of the lower fiber layer 26 with a silicone resin. It has a thickness of about 200 μm and is arranged in a spot-like spot as shown in FIG. The resin non-slip portion 32 does not slip when the wearer 2 wearing the foot cover 1 contacts the floor surface while walking on the floor surface.

  In order to obtain the foot cover 1, the elongated knitted fabric 10 is bent as shown in FIG. 6, and the side edges 22, 22 of the narrow portions 21 on both sides of the knitted fabric are sewn together to form the strip-shaped narrow portion 7, An overlock stitch is formed between the lower ends 20 and 20 of the upper side 12 corresponding to the upper opening 30 and the lower side 14 corresponding to the lower side of the strip-shaped narrow portion 7 by overcasting. The sewn portions 34 (FIG. 3) of the end sides 22, 22 eliminate the discomfort when the sewn portions come into contact with the skin of the wearer 2 by upper and lower rim stitches, or the sewn portions do not contact the Achilles tendon of the wearer 2. The lengths of the narrow portions 21 and 21 may be changed as described above.

  On the other hand, the sole 5 is temporarily sewn over the entire circumference with the upper fiber layer 24, the cushion material 28, and the lower fiber layer 26 overlapped. Further, the knitted fabric 10 is disposed with the lower fiber layer 26 disposed above, and the middle portion of the lower side 14 of the knitted fabric, that is, the location of the toe portion 16 and both side portions 18 and the periphery of the sole portion 10 are edge-stitched 29 (FIG. 4) stitch together. When the knitted fabric 10 is turned back after the rim seam 29 on the entire circumference, the foot cover 1 is obtained.

  When the heel-pull foot cover 1 is worn in FIG. 3, the band-shaped narrow width part 7 is hooked near the Achilles tendon above the heel part g of the wearer 2, and the toe part a and the both side parts b of the wearer 2 are mainly used. b, and only the heel g is completely exposed. In the foot cover 1, an upper opening 30 which is a wearing mouth is widely opened so as not to be exposed from shoes such as pumps and sneakers when worn, and the upper opening has a substantially elliptical flat surface in a folded state (see FIG. 1). ). The upper opening 30 is prevented from being frayed by edge stitching with a stretchable thread.

  In the foot cover 1 without heels, the instep portion 3 and the band-shaped narrow portion 7 are made of an integrated knitted fabric, and as shown in FIG. Therefore, the bag-shaped instep 3 does not come off when the wearer 2 walks. Since the foot cover 1 merely locks the rear narrow band portion 7 on the upper part of the heel of the wearer 2 and has no heel on the cover itself, the heel of the foot cover falls off from the wearer's 2 foot. There is no.

  The heel-less foot cover 1 has a three-layer structure in which the sole 5 is a cushion material having a thickness of 5 mm interposed between the upper bare fabric and the lower knitted fabric. When the foot cover 1 is worn on the wearer's 2 foot, the impact is moderately reduced during walking, so that the foot cover 1 has a good comfort. When the foot cover 1 is worn in winter, it has a moderate heat retaining effect. When the wearer 2 wears the foot cover 1, the sole of the foot comes in contact with the soft bare fabric, so that comfort is good.

  In the foot cover 1, a resin non-slip portion 32 is formed in a predetermined range above the surface of the lower fiber layer 26 of the sole 5. When the wearer 2 wears the foot cover 1, it does not slip when the floor surface comes into contact with the floor surface during walking, so that comfortable and safe wearing comfort can be maintained.
