JP6449036B2 - Leg wear - Google Patents

Description

  The present invention relates to leg wear worn on a foot, and more particularly to leg wear that suppresses a shift or slippage due to an action such as walking.

  Conventionally, legwear such as socks has been used for the purpose of preventing discomfort and fatigue and cooling when wearing shoes directly on bare feet. For example, when wearing shoes on top of legwear, friction occurs between the legwear and the shoe, and if the friction between the shoe and the legwear exceeds the friction between the foot and the legwear, the legwear moves. Instead of following the movement of the shoe, the leg wear is displaced or removed from the foot. When wear of leg wear causes a shift in leg wear or the like due to an operation such as walking, it affects the comfort, and leg wear that is less likely to slip or take off is demanded. In particular, since the foot cover is configured to be hidden in the shoe when the shoe is worn, the area of the portion covering the foot is small, and the foot cover is likely to be detached during wearing.

  Regarding the suppression of such shift and removal of leg wear, Patent Documents 1 to 6 propose leg wear including various slip preventing portions inside the collar portion covering the collar.

  For example, Patent Documents 1 and 2 propose legwear in which a belt-like non-slip portion is disposed horizontally inside the collar portion. Patent Documents 3 and 4 propose leg wear in which a plurality of protrusion-like or fragment-like non-slip portions are discontinuously arranged inside the collar portion. Further, Patent Documents 5 and 6 propose leg wear in which a planar slip-proof portion is arranged inside the collar portion.

Japanese Utility Model Publication No. 5-19304 (published Mar. 09, 1993) JP-A-9-59804 (published Mar. 04, 1997) Japanese Patent Laid-Open No. 10-292206 (published Nov. 4, 1998) Japanese Patent Laid-Open No. 11-335905 (released on Dec. 07, 1999) Japanese Utility Model Publication No. 6-51207 (published July 12, 1994) Utility Model Registration No. 3182636 (Registered on March 13, 2013)

  As a cause of foot cover slipping or slipping, the foot cover's buttocks are pulled forward due to contact and friction between the ground and the foot during walking, and the position of the anti-slip part shifts. Can be mentioned. In other words, the anti-slip portion arranged inside the buttock fabric moves along with the expansion and contraction of the heel fabric. In addition, the walking mechanism includes not only refraction in the vertical direction of the ankle but also movement in the horizontal direction (the valgus direction or the varus direction), so the fabric of the buttock is pulled in the horizontal direction. . For this reason, the anti-slip portion cannot remain in a predetermined position, and a sufficient anti-slip effect cannot be obtained. As a result, the foot cover is easily displaced or detached.

  However, in the above-described conventional technology, there is a problem that a sufficient anti-slip effect cannot be obtained by the anti-slip part because no consideration is given to the position shift of the anti-slip part due to the expansion and contraction of the fabric of the heel part.

  For example, in the configurations of Patent Documents 1 and 2, since the belt-like anti-slip portion is arranged horizontally long, the expansion and contraction of the fabric of the buttock in the lateral direction is suppressed, but the expansion and contraction of the fabric of the buttock in the vertical direction is suppressed. Can not be suppressed. For this reason, in Patent Documents 1 and 2, a slippage of the anti-slip portion tends to occur in the vertical direction, and a sufficient anti-slip effect cannot be obtained.

  Moreover, in the structure of patent document 3 and 4, since the protrusion-shaped or fragmentary anti-slip | slipping part is dotted and arrange | positioned, the expansion-contraction to the vertical direction and the horizontal direction of the fabric of a collar part cannot be suppressed. . Therefore, in patent documents 3 and 4, it becomes easy to produce the position shift of the non-slip | skid part to the vertical direction and a horizontal direction, and sufficient anti-slip effect cannot be acquired.

  Furthermore, in the configurations of Patent Documents 5 and 6, since the sheet-like non-slip portion is disposed so as to cover the back surface of the heel, it is possible to suppress expansion and contraction of the fabric of the heel portion in the vertical and horizontal directions. However, since the non-slip portion does not fit the heel and a gap is generated, a sufficient anti-slip effect cannot be obtained. Moreover, in the structure of patent document 5 and 6, since the back surface of a heel is covered by a planar slip prevention part, the skin becomes easy to be touched by sweat etc., and the new subject that a wearing comfort falls arises.

  This invention is made | formed in view of the said conventional subject, Comprising: The objective is to provide the legware which can suppress a shift | offset | difference and a removal | desorption suitably, without impairing comfort.

  In order to solve the above-described problems, a legwear according to the present invention is provided at least on a sole part that covers a sole, and a stretchable main body part that includes a heel part that covers a heel, and an inner side of the heel part. A non-slip portion having a lower elasticity than the fabric of the heel portion, and when the vertical direction is defined as the vertical direction and the width direction of the sole portion is defined as the lateral direction, The portion includes a belt-like portion that suppresses expansion and contraction of the fabric of the heel portion in the vertical direction and the horizontal direction.

  As described above, during walking, the cloth of the heel portion is pulled in the vertical direction by the bending operation of the ankle in the vertical direction, and the main body portion is displaced or detached. In addition, the walking mechanism includes not only refraction in the vertical direction of the ankle but also movement in the horizontal direction (the valgus direction or the varus direction), so the fabric of the buttock is pulled in the horizontal direction. As a result, the main body may be displaced or detached.

  Therefore, in the above-described configuration, the anti-slip portion includes a belt-like portion that suppresses expansion and contraction of the fabric of the heel portion in the vertical direction and the horizontal direction. The body part is prevented from slipping while suppressing expansion and contraction.

  For example, by providing the belt-shaped portion so as to extend in two or more different directions, expansion and contraction of the fabric of the heel portion in the vertical direction and the horizontal direction is suppressed over the range in the vertical direction and the horizontal direction in which the band-shaped portion is disposed. The Therefore, the position shift of the anti-slip | skid part accompanying the expansion-contraction of the cloth | dough of a buttocks by operation | movement, such as a walk, can be suppressed.

  In the above configuration, the anti-slip part is composed of a belt-like part, so that the anti-slip part can easily fit into the heel and can obtain a sufficient anti-slip effect, and the skin is less likely to be touched by sweat. Can do.

  Therefore, according to said structure, the legware which can suppress suitably slip | deviating and taking off is achieved, without impairing comfort.

  Moreover, in the legwear which concerns on this invention, the said strip | belt-shaped part may contain the 1st strip | belt-shaped part extended | stretched to a substantially horizontal direction, and the 2nd strip | belt-shaped part extended | stretched to a substantially vertical direction.

  In said structure, the 1st strip | belt-shaped part can suppress the expansion-contraction to the horizontal direction of the cloth | dough of the collar part by the operation | movement of the ankle's horizontal direction (a valgus direction or a varus direction). In addition, the second belt-like portion can suppress the expansion and contraction of the fabric of the buttock in the vertical direction due to the bending operation of the ankle in the vertical direction.

  Therefore, according to said structure, the expansion-contraction to the vertical direction and the horizontal direction of the fabric of a collar part can be suppressed by a non-slip | skid part.

  In the present specification, “stretching substantially in the lateral direction” means stretching in the lateral direction and substantially stretching in the lateral direction. Therefore, the first belt-shaped portion is formed in the lateral direction. On the other hand, it may be stretched in a direction having a slight angle difference. Similarly, “extending substantially in the longitudinal direction” means extending in the longitudinal direction and substantially extending in the longitudinal direction, and accordingly, the second band-shaped portion has a certain amount with respect to the longitudinal direction. You may extend | stretch in the direction which has an angle difference.

  Moreover, in the legwear which concerns on this invention, the said strip | belt-shaped part contains two said 2nd strip | belt-shaped parts, and the two said 2nd strip | belt-shaped parts may be provided so that a rib may be pinched | interposed.

  In the above configuration, by providing the two second belt-like portions so as to sandwich the ribs, the expansion and contraction in the vertical direction of the portion where the fabric is particularly easy to move (the central portion on the rear surface of the ribs) is suitably suppressed. be able to.

  Therefore, according to said structure, the expansion-contraction to the vertical direction of the cloth | dough of a collar part can be suppressed effectively.

  Moreover, in the legwear which concerns on this invention, the said 1st strip | belt-shaped part is provided so that Achilles tendon may be crossed, and two said 2nd strip | belt-shaped parts are the said foot side part side from the both ends of the said 1st strip | belt-shaped part. It may be stretched.

  In the above-described configuration, the first belt-like portion is provided above the portion where the fabric is particularly easy to move in the heel portion (the central portion on the back of the rib), and the second belt-like portions are provided on the left and right sides. Expansion and contraction in the lateral direction can be suitably suppressed.

  Therefore, according to said structure, the expansion-contraction to the vertical direction and the horizontal direction of the fabric of a collar part can be suppressed effectively.

  Moreover, in the legwear which concerns on this invention, the said strip | belt-shaped part contains the some 3rd strip | belt-shaped part extended in the direction different from a substantially vertical direction and a substantially horizontal direction, and the said some 3rd strip | belt-shaped part crosses mutually. May be.

  In the above configuration, the anti-slip portion includes a plurality of third belt-like portions extending in a direction different from the substantially vertical direction and the substantially horizontal direction, and is provided so that these third belt-like portions intersect. Even in such a configuration, expansion and contraction in the vertical and horizontal directions of the fabric of the heel portion can be suppressed over the range in the vertical and horizontal directions where the plurality of third belt-shaped portions are arranged.

  Therefore, according to said structure, the anti-slip which can suppress the expansion-contraction to the vertical direction and horizontal direction of the cloth | dough of a collar part combining the 3rd strip | belt-shaped part extended | stretched in the direction different from a substantially vertical direction and a substantially horizontal direction. Can be realized.

  Moreover, in the legwear which concerns on this invention, the said strip | belt-shaped part may contain the 4th strip | belt-shaped part extended | stretched in curvilinear form.

  According to said structure, the expansion-contraction to the vertical direction and the horizontal direction of the cloth | dough of a collar part can be suppressed by the curvilinear 4th strip | belt-shaped part from which an extending | stretching direction changes continuously.

  For example, by providing the fourth belt-like portion so as to surround a portion where the fabric is particularly easy to move in the heel portion (the central portion on the back of the rib), the expansion and contraction of the heel portion in the vertical and lateral directions is effectively suppressed. be able to.

  Moreover, in the legwear which concerns on this invention, the said strip | belt-shaped part may be formed in series.

  According to said structure, since a strip | belt-shaped part is formed in series, it becomes difficult to produce the partial position shift of a strip | belt-shaped part, Therefore The expansion-contraction to the vertical direction and the horizontal direction of the fabric of a collar part is more effective. Can be suppressed.

  Moreover, in the legwear which concerns on this invention, the said anti-slip | skid part may apply | coat resin with a higher friction coefficient than the material | dough of the said main-body part, and may be formed in the sheet form.

  In the above configuration, a resin having a higher coefficient of friction than the fabric of the main body can be easily and uniformly applied to the entire substrate.

  According to said structure, the expansion-contraction to the vertical direction and the horizontal direction of the fabric of a collar part can be suppressed more effectively. Further, by providing a sheet-like non-slip portion in which the resin is applied to the base material on the inner side of the collar portion, it is possible to effectively suppress the shift and removal of the leg wear.

  Therefore, according to the present invention, there is an effect that it is possible to provide legwear that can suitably suppress displacement and removal without impairing comfort.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS. In the present embodiment, a case where the present invention is applied to a foot cover (leg wear) will be described as an example.

  However, the present invention is not limited to the foot cover that exposes the instep and the ankle, but can also be applied to various types of legwear configured to cover the instep and the ankle.

[Configuration of foot cover 1]
FIG. 1 is a perspective view showing an external configuration of a right foot cover 1 according to the present embodiment. As shown in FIG. 1, the foot cover 1 includes a main body portion 2 worn on the foot F, and a non-slip portion 3 that prevents the main body portion 2 from shifting or coming off.

(Main part 2)
The main body 2 is formed of a sole 21 that covers the sole, a toe 22 that covers the toe, a side 23 that covers both sides of the foot F, and a heel 24 that covers the heel. Further, the main body 2 is provided with a foot opening 2 a for putting a foot in and out on the opposite side to the sole 21.

  The wearing mouth portion 2a is greatly opened so that the instep and the ankle are exposed, whereby the entire main body portion 2 is hidden in the shoe when the shoe is worn.

  The main body 2 is formed of a highly stretchable fabric, and preferably has good breathability and hygroscopicity. For example, natural fibers such as cotton, hemp, hair, silk, or rayon, nylon, acrylic Chemical fibers such as polyester are preferred.

  In addition, in this embodiment, although the main-body part 2 is knitted with the knitting machine, the main-body part 2 can also be formed by sewing the cloth woven by the weaving machine.

(Non-slip part 3)
The anti-slip portion 3 is a band-shaped member made of a material having lower elasticity than the fabric of the main body 2 and a higher friction coefficient than the fabric of the main body 2. The anti-slip portion 3 is provided in a region on the inner side of the heel portion 24, below the heel (outer fruit, inner fruit), and on the rear side. Prevents the deviation and removal of 2.

  The material of the non-slip portion 3 is not particularly limited as long as it has lower elasticity than the fabric of the main body 2 and has a higher friction coefficient than the fabric of the main body 2. For example, various materials can be used besides a resin having a relatively high frictional resistance with the skin (natural resin such as natural rubber, synthetic resin such as silicon rubber and urethane rubber).

In addition, the anti-slip part 3 according to the present embodiment is formed in a sheet shape by applying (applying) a resin or the like to the anti-slip part forming fabric (base material) and attaching it to the collar part 24 of the main body part 2. It is attached. Thus, by forming the anti-slip | skid part 3 in a sheet form, it can be easily affixed inside the collar part 24 of the main-body part 2 which is a three-dimensional curved surface.
The shape of the resin or the like affixed to the anti-slip portion forming fabric does not need to match the shape of the anti-slip portion forming fabric, and may be an arbitrary pattern shape such as a particle shape or a floral pattern. Furthermore, it is preferable to provide fine irregularities on the surface of resin or the like to increase the friction coefficient.

  The anti-slip portion forming fabric (base material) is preferably a fabric having a certain stretchability. By using a fabric having a certain stretchability as a base material, the fabric itself of the heel portion 24 is directly applied to the fabric of the heel portion 24 (main body portion 2) without hindering the fitting of the fabric itself of the heel portion 24 to an appropriate shape. Compared with the case where it affixed, the expansion-contraction to the vertical direction and the horizontal direction of the cloth | dough of the collar part 24 can be suppressed more effectively.

  Moreover, it is preferable that the anti-slip | skid part formation fabric (base material) is an uneven fabric. For example, when there are knitted or textured irregularities such as knitted fabrics or woven fabrics, fine irregularities can be easily provided on the surface of the resin or the like by thinly applying the resin or the like, and the friction coefficient can be increased.

  In addition, it is also possible to apply | coat or stick resin etc. directly to the cloth | dough of the collar part 24 of the main-body part 2. FIG.

  FIG. 2 is a schematic diagram for explaining the shape of the slip stopper 3 shown in FIG. 1. FIG. 2 (a) is a rear view of the slip stopper 3 and FIG. 2 (b). These are side views of the anti-slip | skid part 3. FIG. In FIG. 2A, the Achilles tendon A is omitted.

  As shown in FIGS. 2A and 2B, the anti-slip portion 3 has a vertical direction (x direction in the drawing) perpendicular to the sole 21 and a width direction of the sole 21. Is defined as the horizontal direction (y direction in the figure), it is a shape in which a plurality of band-shaped portions extending in different directions are combined so as to suppress expansion and contraction of the fabric of the heel portion 24 in the vertical direction and the horizontal direction. (In the figure, the direction from the heel to the toe is shown as the z direction.)

  Specifically, the anti-slip portion 3 includes a horizontal belt-like portion (first belt-like portion) 31 that extends in the substantially transverse direction across the Achilles tendon A and two vertical belt-like portions (second belt) that extend in the substantially vertical direction. Strips) 32a and 32b, and the two vertical strips 32a and 32b are provided so as to sandwich the rib B (or rib protrusion C). In the present embodiment, the two vertical belt-like portions 32a and 32b are arranged so as to have a slight angular difference with respect to the vertical direction so that the distance gradually increases toward the sole portion 21.

  In this way, by combining the horizontal belt-like portion 31 and the two vertical belt-like portions 32a and 32b into a substantially U-shape opened on the sole 21 side, the fabric of the heel portion 24 is moved in the vertical and horizontal directions. Expansion and contraction can be suppressed.

  In addition, two sides that are in contact with both end portions of the anti-slip portion 3 in the vertical direction (that is, the upper end portion of the horizontal band portion 31 and the lower end portions of the vertical band portions 32a and 32b) and parallel to the horizontal direction, and the horizontal direction In a rectangular region R defined by two sides that are in contact with both ends of the anti-slip portion 3 (that is, the left end portion of the vertical strip portion 32a and the right end portion of the vertical strip portion 32b) and parallel to the vertical direction, It is preferable that the anti-slip | skid part 3 is provided so that the back center part (for example, rib protrusion C) of the rib B may be included. Thereby, the expansion-contraction to the vertical direction and horizontal direction of the part which cloth | dough easily moves especially in the collar part 24 can be suppressed suitably.

  Further, as in the present embodiment, the anti-slip portion 3 is formed in a series by connecting the horizontal belt portion 31 and the vertical belt portion 32a, and the horizontal belt portion 31 and the vertical belt portion 32b, respectively. Is preferred. Thereby, since it becomes difficult to produce the partial position shift of the anti-slip | skid part 3, the expansion-contraction to the vertical direction and the horizontal direction of the fabric of the collar part 24 can be suppressed still more effectively.

[Effect of foot cover 1]
During walking, particularly when the fabric of the heel portion 24 does not follow the movement in the vicinity of the Achilles tendon A, the fabric of the heel portion 24 is pulled in the longitudinal direction. In addition, the walking mechanism includes not only a bending operation of the ankle in the vertical direction but also a movement in the horizontal direction (the valgus direction or the varus direction), and therefore the fabric of the heel part 24 is pulled in the horizontal direction. The Therefore, if only one of the expansion and contraction of the fabric of the collar portion 24 in the vertical direction and the expansion and contraction of the fabric of the collar portion 24 in the lateral direction is suppressed, the anti-slip portion associated with the expansion and contraction of the fabric of the collar portion 24 is suppressed. Misalignment cannot be suppressed.

  Therefore, in the foot cover 1, the horizontal belt-like portion 31 and the two vertical belt-like portions 32 a and 32 b are opened on the foot bottom 21 side so as to suppress the expansion and contraction of the fabric of the heel 24 portion in the vertical and horizontal directions. It is combined with an approximately U-shape.

  In the foot cover 1, the horizontal band 31 is located above the part, the vertical band 32 a is located on the left side, and the vertical band 32 a is located on the right side so as to surround a portion where the fabric easily moves (the central part on the back of the rib B). A mold strip portion 32b is provided. Therefore, the anti-slip | skid part 3 can suppress suitably the expansion-contraction to the vertical direction and horizontal direction of the cloth | dough of the collar part 24. FIG.

  Furthermore, since the main body 2 is formed of a highly stretchable fabric, the fabric itself of the heel portion 24 fits appropriately in the shape of the heel. Therefore, a sufficient anti-slip effect can be obtained without the foot cover 1 being displaced following the movement of a shoe or the like.

  Moreover, since the anti-slip | skid part 3 is the shape which connected the some strip | belt-shaped part in series, while being able to fit the anti-slip | skid part 3 to a collar easily and obtaining sufficient anti-skid effect, air permeability is also ensured enough. Since it is made, the skin can be made less susceptible to sweat.

  In addition, it is known that the shape of the raft around the foot through the heel and the instep does not change much during walking. Therefore, even if the expansion and contraction of the fabric of the heel part 24 is suppressed by the anti-slip part 3, uncomfortable feeling at the time of wearing hardly occurs. On the other hand, for example, the sole 21 (width of the middle foot, etc.) expands and contracts due to the extension of the arch of the sole, so that suppressing the expansion and contraction of the fabric of the sole 21 tends to cause discomfort during wearing. As described above, by providing the anti-slip portion 3 in the collar portion 24, it is possible to prevent the foot comfort of the foot cover 1 from being lowered.

  Therefore, according to the present embodiment, it is possible to realize the foot cover 1 that can suitably suppress the displacement and the removal without impairing the comfort.

[Modification 1]
FIG. 3A to FIG. 3M are rear views showing a modification of the anti-slip portion 3 according to the present embodiment.

  The anti-slip | skid part 3 should just be able to suppress the expansion-contraction to the vertical direction and horizontal direction of the cloth | dough of the collar part 24, and is not limited to the shape mentioned above.

  For example, as shown in FIG. 3 (a), the non-slip portion 3 has a substantially H-shaped configuration in which a horizontal strip portion 31 is provided so as to connect the central portions of two vertical strip portions 32a and 32b. It may be a shape.

  Further, as shown in FIG. 3B, the anti-slip portion 3 has a substantially T-shaped shape in which the central portion of the horizontal strip 31 is connected to the upper end of the vertical strip 32c extending in the vertical direction. It may be. Alternatively, as shown in FIG. 3 (c), the anti-slip portion 3 has an inverted T-shape in which the central portion of the horizontal strip 31 is connected to the lower end of the vertical strip 32c extending in the vertical direction. The shape may also be

  Further, as shown in FIG. 3 (d), the anti-slip portion 3 has a lower end portion of two parallel vertical strips 32c and 32d extending in a substantially vertical direction connected by a horizontal strip 31. The substantially U-shaped shape opened to the wear mouth part 2a side may be sufficient.

  Further, as shown in FIG. 3 (e), the anti-slip portion 3 has a horizontal belt shape in which upper ends of two parallel vertical belt portions 32c and 32d extending in a substantially vertical direction extend in a substantially horizontal direction. A substantially square shape in which the lower end portions of the vertical strip portions 32c and 32d are connected by the horizontal strip portion 31b may be used.

  As shown in FIG. 3 (f), the anti-slip portion 3 includes two oblique belt-shaped portions (third belt-shaped portions) 33a and 33b extending in an oblique direction different from the substantially vertical direction and the substantially horizontal direction. In addition, a substantially X-shaped shape in which these oblique belt-like portions 33a and 33b intersect with each other at the center may be used.

  Further, as shown in FIG. 3G, the anti-slip portion 3 has a substantially V-shaped shape in which the lower end portion of the oblique strip portion 33a and the lower end portion of the oblique strip portion 33b intersect. Also good. Alternatively, as shown in FIG. 3 (h), the anti-slip portion 3 has an inverted V-shaped shape in which the upper end portion of the oblique strip portion 33a and the upper end portion of the oblique strip portion 33b intersect. Also good.

  Further, as shown in FIG. 3 (i), the anti-slip portion 3 has two vertical strips 32c and 32d that extend in the substantially vertical direction and the upper end portions of the two parallel belt-shaped portions 32c and 32d are connected in a substantially V shape. A substantially M-shaped shape connected by the slanted belt-like portions 33a and 33b may be used.

  Further, as shown in FIGS. 3 (i) and 3 (k), the anti-slip portion 3 has a curved curved belt-like portion (fourth belt-like portion) 34 having a central portion on the back surface of the rib B (for example, The curved shape may be arranged so as to surround the rib bulge C).

  Further, as shown in (l) of FIG. 3 and (m) of FIG. 3, the anti-slip portion 3 includes two curved strips 34a and 34b intersecting each other, and the curved strips 34a and 34b You may arrange | position so that the back center part (For example, rib protrusion C) of the bone B may be enclosed.

  3A to 3M, the central portion of the rectangular region R is disposed with the central portion of the back surface of the rib B (for example, rib protrusion C). Thus, it is preferable to provide the anti-slip part 3. Thereby, expansion / contraction to the vertical direction and the horizontal direction of the collar part 24 can be suppressed suitably, and the position shift of the anti-slip | skid part 3 can be suppressed.

  Moreover, the anti-slip | skid part 3 is not limited to these shapes. The non-slip portion 3 is configured so that the horizontal belt-like portions 31, 31 a, and 31 b, the vertical belt-like portions 32 a, 32 b, 32 c, and 32 d, and the slant type so that the expansion and contraction of the fabric of the heel portion 24 can be suppressed. The shape may be a combination of the belt-shaped portions 33a and 33b and the curved belt-shaped portion 34 as appropriate.

[Modification 2]
FIG. 4 is a rear view showing another modification of the anti-slip portion 3 according to the present embodiment. As shown in FIG. 4, in the anti-slip portion 3, the horizontal belt portion 31 and the vertical belt portion 32 a and the horizontal belt portion 31 and the vertical belt portion 32 b do not necessarily have to be connected.

  Even if it is such a shape, the horizontal strip | belt-shaped part 31 can suppress the expansion-contraction to the horizontal direction of the fabric | dough of the buttocks by the operation | movement of the ankle's horizontal direction (a valgus direction or a varus direction). Further, the vertical belt-like portions 32a and 32b can suppress the expansion and contraction in the vertical direction of the fabric of the heel portion 24 due to the bending operation of the ankle in the vertical direction.

  However, since the horizontal belt portion 31 and the vertical belt portion 32a, and the horizontal belt portion 31 and the vertical belt portion 32b are connected and formed in series, partial slippage of the anti-slip portion 3 is less likely to occur. . Therefore, the horizontal strip 31 and the vertical strip 32a, and the horizontal strip 31 and the vertical strip 32b are connected to each other, thereby effectively suppressing the expansion and contraction of the fabric portion 24 in the vertical and horizontal directions. This is preferable because it can be performed.

  The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope shown in the claims, and embodiments obtained by appropriately combining technical means disclosed in different embodiments. Is also included in the technical scope of the present invention.

  Hereinafter, it will be as follows if one Example of this invention is described based on FIGS. In this example, the anti-slip effect by the leg wear according to the present invention was verified.

  FIG. 5A to FIG. 5F are rear views showing the shapes of the anti-slip portions tested in this example. As shown in FIGS. 5 (a) and 5 (b), in this embodiment, as the anti-slip portion of the present invention, the anti-slip portion having a substantially U-shape opened to the sole 21 side. 3a and the anti-slip | skid part 3b were prepared. The difference between the anti-slip portion 3a and the anti-slip portion 3b is that the two vertical band portions 32a 'and 32b' of the anti-slip portion 3b are different from the width of the two vertical band portions 32a and 32b of the anti-slip portion 3a. This is the point where the width of is narrowed.

Further, as shown in FIGS. 5 (c) to 5 (f), as a comparison object, the anti-slip portion 103a constituted by the vertical belt-like portions 32a and 32b by removing the horizontal belt-like portion 31 from the anti-slip portion 3a. A non-slip portion 103b configured by a vertical strip portion 32c extending in a substantially vertical direction, a non-slip portion 103c configured by a horizontal strip portion 31c extending in a substantially horizontal direction, and a horizontal strip portion wider than the horizontal strip portion 31c. Each of the anti-slip portions 103d configured by 31d was prepared.

Yes, (b) of FIG. 7 is a test result in the case where a pantyhose is attached to a female standard foot mannequin and a foot cover provided with each anti-slip part is put on, and (c) of FIG. It is a test result at the time of putting a foot cover which provided each slip prevention part on a raw foot.

In Table 1 and FIGS. 7A to 7C, the foot cover provided with the anti-slip portion 3a is the first embodiment, and the foot cover provided with the anti-slip portion 3b is the second embodiment. Comparative Example 1 is the foot cover provided with the portion 103a, Comparative Example 2 is the foot cover provided with the anti-slip portion 103b, Comparative Example 3 is the foot cover provided with the anti-slip portion 103c, and is the foot cover provided with the anti-slip portion 103d. This is shown as Comparative Example 4. Moreover, the numerical value in the parenthesis in Table 1 is a value obtained by dividing the tensile force (N / mm ² ) by the area (mm ² ) of the anti-slip part, and indicates the anti-slip force per unit area of each anti-slip part. Is an index.

  As shown in Table 1 and FIG. 7 (a), when a foot cover provided with a non-slip portion is mounted on a female standard foot mannequin, the foot cover of Example 1 and the foot cover of Example 2 are: The foot cover could not be removed even if it was pulled at the limit that the fabric of the foot cover could withstand.

  On the other hand, the average value of the tensile force when the foot cover of Comparative Example 1 was removed was 0.51 ± 0.03, and the average value of the tensile force when the foot cover of Comparative Example 2 was removed was 0.46. ± 0.03, the average value of the tensile force when the foot cover of Comparative Example 3 is removed is 0.57 ± 0.02, the average value of the tensile force when the foot cover of Comparative Example 4 is removed is 1.51 ± 0.02.

  In addition, as shown in Table 1 and FIG. 7B, when the foot cover provided with each non-slip portion is mounted on the female standard foot mannequin with pantyhose, the foot cover of Example 1 is The average value of the tensile force when removed was 2.59 ± 0.22, and the average value of the tensile force when the foot cover of Example 2 was removed was 2.53 ± 0.03.

  In contrast, the average value of the tensile force when the foot cover of Comparative Example 1 was removed was 0.56 ± 0.02, and the average value of the tensile force when the foot cover of Comparative Example 2 was removed was 0.60. ± 0.01, the average value of the tensile force when the foot cover of Comparative Example 3 was removed was 0.64 ± 0.03, and the average value of the tensile force when the foot cover of Comparative Example 4 was removed was 1.08 ± 0.03.

  In addition, as shown in Table 1 and FIG. 7C, when the foot covers provided with the anti-slip portions were put on the raw feet, the average value of the tensile force when the foot cover of Example 1 was removed. Was 2.94 ± 0.09, and the average value of the tensile force when the foot cover of Example 2 was removed was 2.60 ± 0.09.

  On the other hand, the average value of the tensile force when the foot cover of Comparative Example 1 was removed was 0.38 ± 0.01, and the average value of the tensile force when the foot cover of Comparative Example 2 was removed was 0.37. ± 0.03, the average value of tensile force when the foot cover of Comparative Example 3 is removed is 0.42 ± 0.01, and the average value of tensile force when the foot cover of Comparative Example 4 is removed is 0.74. ± 0.02.

  In this way, when a female standard foot mannequin is fitted with foot covers with anti-slip parts, pantyhose is attached to the female standard foot mannequin and foot covers with anti-slip parts are put on. In any case, the foot covers of Example 1 and Example 2 are the same as the foot covers of Comparative Examples 1 to 4 in any case where the foot covers provided with the respective anti-slip portions are put on the raw feet. Compared to that, it was difficult to remove and a high anti-slip effect was obtained.

  In the foot covers of the first embodiment and the second embodiment, the horizontal band 31 and the vertical band sections 32a and 32b or the horizontal band section 31 and the vertical band sections 32a 'and 32b' This is because as a result of suppressing the expansion and contraction of the fabric in the vertical and horizontal directions, the position shift of the anti-slip portion due to the expansion and contraction of the fabric of the collar portion 24 is suppressed, and a sufficient anti-slip effect by the anti-slip portion was obtained. .

  On the other hand, in the foot covers of Comparative Examples 1 to 4, the fabric of the collar portion 24 expands and contracts in the vertical direction or the horizontal direction. For example, in the foot cover of Comparative Example 1, since the two vertical belt-like portions 32a and 32b of the anti-slip portion 103a are not connected, the fabric of the heel portion 24 expands and contracts in the lateral direction. For this reason, in the foot covers of Comparative Examples 1 to 4, the slip-preventing portion was displaced due to the expansion and contraction of the fabric of the collar portion 24, and a sufficient anti-slip effect by the slip-preventing portion was not obtained.

  Thus, in the present Example, it was confirmed that the high slip prevention effect is acquired by the legware which concerns on this invention.
