Socks

Technical field

[0001] The present invention relates to a sock, for example, a sock that is knitted by a circular knitting machine so that a desired tightening pressure is applied to a specific part of a foot when the sock is worn.

Background art

[0002] The conventional socks that are the background of the present invention include, for example, a sock having a structure that is easy to wear and has a structure that improves the motor function. In the foot part that reaches the foot of the foot, there was one that formed a tightening region with stretchable material over the entire circumference of the sole and instep, that is, almost the entire foot part formed in a cylindrical shape (for example, (See Patent Document 1). The tightening area is formed, for example, in a rubber knitted structure in which rubber yarn is knitted on a specific course, and by applying an appropriate tightening force to the foot, the sole is lifted to try to support the arch structure of the arch Is. The tightening area is divided into a strong tightening area that tightens a range of approximately three fifths on the heel side with a strong force, and a two-fifth range on the toe side is divided into a normal tightening area that has a weak force. In this case, the tightening force varies depending on the type of rubber yarn to be knitted and the size of the rubber knitting eye.If the tightening force in the strong tightening region is 100%, the tightening force in the normal tightening region is 70%. It is formed to the extent.

In this conventional sock, the tightening area is divided into a strong tightening area and a normal tightening area, and the arch structure of the arch is supported in the strong tightening area, and the normal tightening area provides a comfortable state with less feeling of pressure without being overtightened. Trying to realize

Problems to be solved by the invention

[0004] However, in such a conventional sock, for example, as shown in FIG. 16, when looking at the strong tightening region 6a and the normal tightening region 6b, each tightening region 6a and 6 b is uniformly formed with the same knitting structure over the entire circumference in the circumferential direction of the foot 3 formed in a cylindrical shape from the sole 3a to the upper 3b. In addition, since the cross-sectional shape of a person's foot is non-uniform, if the sock 1 formed of a uniform knitted structure is worn in the circumferential direction of the foot 3, the surface force in the circumferential direction of the foot 3 is also The tightening pressure applied to each part of the foot (hereinafter also referred to as “compression pressure”) is different, and the pressure difference from the sock 1 to the applied pressure applied by the instep part, the arch part and the side part of the foot Will occur. In particular, the swell is large and hard, the upper part of the foot is high and wearing pressure, and the hollow is soft! /, The arch part is low and wearing pressure.

In other words, when wearing the sock 1 formed of a uniform knitted structure in the circumferential direction of the foot 3, a large pressure is applied to the instep, and the desired pressure is applied to the arch that plays an important role during exercise. In addition, sufficient support function could not be obtained! / ヽ and ヽぅ had a defect.

On the other hand, for example, as shown in Fig. 6, there are three arch structures A, B, and C with the fulcrum a, the small ryukyu b, and the rib c as fulcrums, It is known that there is a walking line D along the movement (tilting) line of the center of gravity when walking. In this case, a horizontal arch (front arch) A is formed between the a and b in the part that bulges toward the base of the little finger. Between the b and c, the outside of the base 付け of the thumb is connected. An inner vertical arch B (a so-called arch arch) is formed in a large depression on the line, and between the a and c, a small depression on the line connecting the outside of the root force of the little finger 踵An outer longitudinal arch C is formed. From these three arches A, B, and chick, it is also known that the impact during walking is absorbed and relaxed, and the load is distributed to enable stable walking with less burden on the body.

Therefore, the conventional socks 1 that cannot sufficiently support the arch part that plays an important role during exercise do not fully satisfy the function as an auxiliary tool for supporting the inner longitudinal arch B. Effectively sabotaging the three arches on the soles was also inadequate. In other words, with this conventional sock 1, it is difficult to enhance the exercise performance function of the foot during walking and assist in supporting stable walking with less burden on the body! Furthermore, in this conventional sock 1, as shown in FIG. 16, the support direction of the arch is in the circumferential direction of the foot 3, and in this case, the direction in which the arch is lifted straight from the sole 3a toward the instep 3b. Therefore, it did not sufficiently follow the movement of the ankle that contributes to the tilting movement of the foot. In other words, it is preferable that the foot tilting motion during walking first starts from the heel and then continues along the walking line D. In this case, the arch is supported in the direction of the ankle. This is because is more effective. That is, in the conventional sock 1, it was difficult to sufficiently support the arch of the sole (inner vertical arch) among the three arches of the sole, so that the performance performance of the foot decreased and the foot The feeling of fatigue was not reduced.

[0005] Therefore, a main object of the present invention is to provide a sock capable of enhancing the performance ability of the exercise of the foot and reducing the feeling of fatigue by effectively supporting the arch. That is.

Means for solving the problem

[0006] A sock according to the present invention is a sock formed by a knitted fabric structure, and includes an instep part, an arch part, an instep part, and a foot part from the instep to the arch. It includes three areas divided into the foot side part connected to the arch part, and when the socks are worn, the arch part tightening force is X and the foot side part tightening force is Y. The knitting structure of the three regions is changed so that X> Y> Z, where Z is the tightening force of the instep.

In this case, looking at the tightening force (compression pressure) of the parts that are in contact with the three areas, the instep part becomes the mouth support pressure area, the arch part becomes the high support pressure area, and the foot side part Is the middle support pressure area. In other words, in the sock according to the present invention, the tightening force (adhesion pressure) acting on the three support regions corresponding to the non-uniform cross-sectional shape of the foot from the instep to the arch is non-uniform. ) Is configured to change. Therefore, when the sock according to the present invention is worn, it is possible to effectively support and activate the three arches of the sole according to the three support areas. In particular, the arch part, which is the pressure support area, is more effectively applied with a tightening force (compression pressure), so the arch part is more effective during exercises such as walking and running. Lift the arch arch (inside Longitudinal arch) function can be supported and supported.

In the sock according to the present invention, the knitting of the knitted fabric structure in the three regions is expressed by OC as the stretchability of the knitted fabric structure of the arch, and β as the stretchability of the knitted fabric structure of the foot side portion. When the stretchability of the knitted fabric structure is γ, the knitted fabric structure of the three regions is knitted so that it becomes a β β γ!

In this case, the stretchability of the knitted fabric structure in each region is changed according to the desired support force in the three support pressure regions. In other words, even if high pressure is applied to the upper part of the foot, which has a large swell, it is possible to relieve the pressure by the elasticity γ of the knitted fabric structure, and the support force required for the instep is added. Will be. Therefore, like the conventional socks formed with a uniform knitted fabric structure, the support force required for the arch will not be hindered by the pressure exerted on the instep!

Further, in the sock according to the present invention, the knitted fabric structure may be knitted so that the support direction of the arch portion is supported toward the arch portion force and the ankle direction when viewed in the longitudinal direction of the foot. Preferred, things.

In this case, since the support pressure area that is applied to the arch is lifted up toward the ankle, a feeling of wearing is obtained such that the arch is lifted toward the ankle, and the arch of the arch ( It is possible to support and assist the inner longitudinal arch function more effectively. Therefore, when these socks are worn, the foot movement during walking is performed more smoothly along the walking line D.

Further, in the sock according to the present invention, the three regions are further divided into two regions, an inner longitudinal arch side and an outer longitudinal arch side, of the three arches on the sole, and the inner region is located on the inner side of the outer longitudinal arch side. It is even more preferable that the knitted fabric structures of the three regions on the inner longitudinal arch side are knitted so that the tightening force on the longitudinal arch side becomes larger.

In this case, the three areas divided in the circumferential direction of the foot from the instep to the arch are further divided into two on the inner longitudinal arch side and the outer longitudinal arch side of the sole as viewed in the longitudinal direction of the foot. This makes it possible to subdivide the support pressure region. Then, by knitting the knitted fabric structure so that the tightening force on the inner vertical arch side is increased, the arch arch (inner vertical arch) structure has a more desirable arch structure, Arch It becomes possible to give a more desirable support force to the support area of the part. Therefore, in this sock, the three arches of the horizontal arch, the inner vertical arch, and the outer vertical arch are more effective so that the three arch structures of the sole function normally around the inner vertical arch. It becomes possible to support.

The invention's effect

[0007] According to the sock according to the present invention, by effectively supporting the arch, it is possible to obtain a sock that can enhance the performance ability of the exercise of the foot and reduce the feeling of fatigue.

In other words, when wearing the sock according to the present invention, the three arch structures of the soles are desirable, and the foot arches are adjusted to the three arches of the soles so that the arch can also lift up in the ankle direction. Power control of the three support pressure areas in the direction and the vertical direction of the foot becomes possible, so that the activity of the three arch functions on the sole can be achieved centering on the inner vertical arch (arch arch). Therefore, wearing socks according to the present invention prevents flat feet caused by dysfunction due to collapse of the arch (inner vertical arch), open legs caused by dysfunction due to collapse of the lateral arch (front arch), etc. It can be expected as an auxiliary tool for this purpose, and a comfortable wearing feeling can also be obtained. In addition, if the socks according to this invention are worn, the outer longitudinal arch can be activated, so that when walking, the tilting movement along the normal walking line can be promoted and the body is not burdened. Efficient walking is possible, which helps to reduce foot fatigue and prevent injury.

[0008] The above-mentioned object, other objects, features, and advantages of the present invention will become more apparent from the following description of the best mode for carrying out the invention with reference to the drawings.

BEST MODE FOR CARRYING OUT THE INVENTION

[0011] The sock that works on the present invention can enhance the performance performance of the movement of the foot, and

In order to reduce the feeling of fatigue, the area that contacts the circumferential direction of the part from the instep of the sock foot to the arch formed by the knitted fabric structure is divided into three regions, the instep, the arch and the side of the foot This was realized by controlling the support force of each region by changing the knitting of the knitted fabric structure according to the support force (tightening force) required for each region.

Furthermore, in the socks that can be used in the present invention, the inner arch is improved by effectively supporting the arch of the arch, particularly the arch of the arch, and lifting the support area of the arch in the ankle direction. The three arches on the sole of the foot centered on the arches can be skillfully regenerated and activated. Therefore, when the sock according to the present invention is worn, it is possible to relieve fatigue and burden on the foot and enhance the exercise performance function. In other words, it excels in motor function when worn and reduces fatigue due to prolonged exercise.

[0012] Fig. 1 is an illustrative side view showing an example of an embodiment of a sock according to the present invention. FIG. 2 is a perspective view showing a main part when the sock shown in FIG. 1 is worn. FIG. 3 is a perspective view showing another main part when the sock shown in FIG. 1 is worn.

The sock 10 that is effective in the present embodiment is a sock formed by a knitted fabric structure, and is used as a support compression region divided into three regions in the circumferential direction of the foot from the instep to the arch. Includes upper 12, arch 14 and foot side 16. The foot side surface portion 16 is disposed between the instep portion 12 and the arch portion 14, and is connected to the instep portion 12 and the arch portion 14. In this embodiment, the foot side surface portion 16 is sandwiched between the instep portion 12 and the arch portion 14 and is disposed so as to be covered with the instep portion 12. Arch 14 and The longitudinal lengths of the feet of the foot side surface portion 16 are formed substantially the same. Further, the length of the arch portion 14 and the foot side surface portion 16 in the circumferential direction of the foot arch portion 14 is formed to be several times longer than that of the foot side surface portion 16, for example.

[0013] When the sock 10 is worn, the sock 10 has a tightening force of the arch portion 14 as X, a tightening force of the foot side surface portion 16 as Y, and a tightening force of the instep portion 12. When Z is set, the knitted fabric structure of the three regions of the instep part 12, the arch part 14, and the foot side part 16 is knitted so that X> Y> Z. In this case, when the elasticity of the knitted fabric structure of the arch part 14 is represented, the elasticity of the knitted fabric structure of the foot side part 16 is j8, and the elasticity of the knitted structure of the instep part 12 is γ, α < In order to satisfy β <γ, that is, by changing the knitting method of the knitted fabric structure in the three areas of the instep part 12, the arch part 14 and the foot side part 16, the elasticity of the knitted fabric structure in each area is improved. A difference is given, and this gives a pressure difference to the clamping force X, Υ, Ζ in each region.

[0014] In the sock 10 of this embodiment, the instep portion 12 is formed of, for example, a flat knitted portion and a mesh (watermark) portion as shown in FIGS. As shown in Fig. 8, the flat knitted portion has a flat portion where the front yarn and the back yarn are doubled, and the mesh (openwork) portion is a back yarn as shown in Fig. 8. Only the knitted fabric is knitted into flat knitting, and the surface yarn is not knitted, and the knitted fabric is inserted. In this case, meshes (watermarks) are arranged in all courses, and in each tool, two meshes are arranged every second. An elastic yarn such as a rubber yarn is inserted into the flat knitting portion. In FIG. 8, the straight line portion of the elastic yarn indicates that the elastic yarn is inserted and arranged between the flat stitch and the flat stitch, and the elastic yarn is the reverse U-shaped portion of the elastic yarn. Indicates that is in a free state.

In the knitted fabric structure of the instep part 12, a mesh (watermark) part is knitted in each course, so that the knitted fabric structure has high elasticity. In addition, by arranging the mesh (watermark) part, the breathability and heat dissipation are improved, and the sebum and sweat odors of the wearer's foot are difficult to block.

[0015] Like the instep portion 12, the side surface portion 16 is formed of a flat knitted portion and a mesh (openwork) portion, but is less knitted than the knitted fabric structure of the instep portion 12. It has become. In other words, the knitted fabric structure of the foot side portion 16 is different from that of the instep portion 12 in FIG. As shown in Fig. 12, in particular, for example, flat knitting and mesh (watermark) portions are arranged every other course. In addition, elastic yarn such as rubber yarn is inserted into the flat knitted portion every other stitch in the wale direction. In FIG. 12, the straight portion of the elastic yarn indicates that the elastic yarn is inserted and arranged between the flat stitch and the flat stitch, and the inverted U-shaped portion of the elastic yarn is free of the elastic yarn. It shows that it is in the state of.

In the foot side surface portion 16, flat knitted portions are knitted every other course, so that the foot side portion 16 is formed into a knitted fabric structure having a smaller elasticity than the instep portion 12 described above.

For example, as shown in FIGS. 9 and 10, the arch portion 14 is formed of a flat knitted portion and, for example, a second float (floating) portion formed by floating knitting. In this case, flat knitting parts are arranged every other course. In addition, elastic yarn such as rubber yarn is inserted into the flat knitting portion and the floating knitting portion every other stitch in the wale direction. In FIG. 10, the straight portion of the elastic yarn indicates that the elastic yarn is inserted between the flat stitch and the flat stitch or between the float and the float. The inverted U-shaped part indicates that the elastic yarn is free.

In this arch portion 14, flat knitted portions are arranged every other course, and a float (floating) portion is knitted every other course, so that it is more elastic than the foot side portion 16 described above. It is formed into a small knitted fabric structure. The arch portion 14 can be knitted with reinforcing yarn (mole) that forms the same loop as the back yarn, for example. As the additional thread, for example, an elastic thread may be used.

[0017] Further, in the sock 10 of the present embodiment, the arch 14 is viewed in the longitudinal direction of the foot and is supported from the arch to the ankle, for example, as shown in Figs. As shown in FIG. 3 and FIG. 4, lift-up stitches 18 are inserted and knitted into the knitted fabric yarns and weaves of the arch portion 14 and the foot side surface portion 16. In this case, a plurality of rows of lift-up stitches 18 are inserted and knitted so as to skew obliquely upward from the arch toward the ankle. As shown in FIG. 13 and FIG. 14, these lift-up stitches 18 are, for example, a mesh (openwork) portion on the arch portion 14 and the foot side surface portion 16 diagonally upward from the arch portion toward the ankle. It is formed by inserting and organizing to skew. In FIGS. 13 and 14, although not shown for convenience, the foot side surface portion 16 side is not shown. Each of the flat knitting portion, the flat knitting portion on the arch 14 side, and the floating knitting portion is knitted with elastic yarn such as rubber yarn.

[0018] Since the lift-up stitches 18 are inserted into the knitted fabric structure of the arch portion 14 and the foot side surface portion 16, the arch portion is tightened so as to be effectively lifted up in the ankle direction. For example, as shown in FIGS. 2 and 3, the knitted fabric structure of the arch portion 14 and the foot side surface portion 16 can follow the movement of the ankle. It should be noted that the pattern and the number of courses of the mesh (watermark) portion inserted into the knitted fabric structure of the arch portion 14 and the foot side surface portion 16 can be appropriately changed.

[0019] Further, when viewed from the sole, these lift-up stitches 18 are arranged in a mountain shape as shown in FIG. 5, for example. When the center line of the foot indicated by the alternate long and short dash line extending in the vertical direction of the sole of the foot is defined as the reference line CL-CL, each lift-up stitch 18 has a peak t of the mountain shape on the reference line CL-CL. Will be located. Each lift-up stitch 18 has a ridge line 18a extending from the top of the mountain to the inside and the outside of the foot, respectively. As shown in FIG. 5, the left and right ridge lines 18a are connected to the reference line CL. — Arranged symmetrically around CL.

[0020] In this case, in the sock 10 of this embodiment, the three area forces of the instep part 12, the arch part 14, and the foot side part 16 are viewed from the sole, for example, as shown in FIG. — Centered on CL, it is further divided into two areas: the inner longitudinal arch B side and the outer longitudinal arch C side. That is, three support pressure regions are formed on the inner longitudinal arch B side and the outer longitudinal arch C side, respectively, with the reference line CL-CL as the center. Then, the knitted fabric structure of the three regions on the inner longitudinal arch B side is knitted so that the tightening force on the inner longitudinal arch B side becomes larger than the clamping force on the outer longitudinal arch C side.

In the lift-up stitch 18 described above, when viewed from the sole, as shown in FIG. 5, the peak apex t of the lift-up stitch 18 is positioned on the foot reference line CL-CL. However, as shown in FIG. 15, for example, as shown in FIG. 15, the peak portion t of the lift-up stitch 18 is an arch-shaped reference line CL corresponding to the line of the inner vertical arch B (arch arch). — It is better to place it on the CL. In this case, the three areas of the instep part 12, the arch part 14 and the foot side part 16 are the three areas of the sole. Can support A, B, C more effectively.

[0022] In the sock 10 of the present embodiment, when the sock 10 is worn, the instep part 12 becomes a low support pressure region when the pressure applied to the parts that are in contact with the three regions is examined. The portion 14 becomes a high support pressure region, and the foot side surface portion 16 is formed in the middle support pressure region.

By the way, the pressure that the sock force worn on the person's foot is usually applied to each partial force in the circumferential direction of the foot assuming that the sock is a uniform knitted fabric and the cross-sectional shape of the person's foot is uniform. Force that applies uniform pressure to the foot Actually, since the cross-sectional shape of the human foot is uneven, if the knitted fabric structure of the socks is uniform, the force is applied to the foot from the circumferential direction of the foot The pressure becomes different, and a pressure difference occurs in the tightening pressure (adhesion pressure) acting on each part in the circumferential direction of the foot.

[0023] On the other hand, in the sock 10 of the present embodiment, the cross-sectional shape of the foot from the instep of the person to the arch is a non-uniform cross-sectional shape, and acts on the three support regions. It is configured to change the wearing pressure. Therefore, it is possible to effectively support and activate the three arches of the sole (see A, B, and C in FIG. 6) according to the three support areas. In this case, since the arch portion 14 which is the high support pressure region is more effectively applied with pressure, the arch portion of the arch can be lifted more effectively during walking, running, etc. Supports (inner vertical arch) function.

[0024] Further, in the sock 10 of the present embodiment example, as described above, the stretchability of the knitted fabric structure in each region is changed according to the support force desired in the three support pressing regions, The For this reason, even if a high pressure is applied to the instep portion of the foot, which has a large swell, the pressure can be eased by the stretch γ of the knitted fabric structure, and the support force required for the instep portion 12 is given. be able to. Therefore, the support force required for the arch, such as a conventional sock formed in a uniform knitted fabric structure, for example, is not likely to be hindered by the pressure on the instep 12! /.

[0025] Furthermore, in the sock 10 of the present embodiment, the support pressure region applied to the arch portion 14 is lifted up in the ankle direction by the knitting of the lift-up stitches 18, so that the arch portion is A feeling of wearing that can be lifted toward the ankle direction is obtained, and Fig. The function of the arch arch (inner vertical arch B) shown in Fig. 1 can be further effectively supported. Therefore, when the sock 10 of the present embodiment is worn, for example, more effectively than the conventional sock 1 shown in FIG. 16 that is supported to lift only in the circumferential direction of the foot, Can prevent flat folds on the arch. Furthermore, with this sock 10, the foot tilting movement during walking can be performed more smoothly along the walking line D shown in FIG.

[0026] According to the sock 10 of this embodiment example, by effectively supporting the arch, it is possible to enhance the performance ability of the exercise of the foot and reduce the feeling of fatigue. In other words, when this sock 10 is worn, power control can be performed in the three support pressure areas in the circumferential direction of the foot and the vertical direction of the foot so that the arch force can also be lifted up in the ankle direction. The function of the three arches A, B, C on the sole can be regenerated and activated with the inner longitudinal arch B (arch of the arch) shown in the center.

[0027] Therefore, if this sock 10 is worn, flat feet caused by dysfunction due to collapse of the arch (inner longitudinal arch B) and open legs caused by dysfunction due to collapse of the lateral arch A (front arch) It can be expected as an auxiliary tool for preventing such problems, and a comfortable wearing feeling can be obtained. Furthermore, since the outer longitudinal arch A can also be activated, it is possible to promote the tilting movement along the normal walking line during walking. For this reason, wearing these socks 10 enables efficient walking without burdening the body and helps to reduce foot fatigue and prevent injuries.

[0028] Further, in the sock 10 of the present embodiment, the three regions divided in the circumferential direction of the foot from the instep to the arch are viewed in the longitudinal direction of the foot, and the inner longitudinal arch B side of the sole The support pressure area is subdivided into two parts on the outer longitudinal arch C side (see Fig. 5). In this case, the knitted fabric structure is knitted so that the tightening force on the inner vertical arch B side is increased. Therefore, an arch structure (inner vertical arch B) is more desirable, and the arch structure is formed. . For this reason, the arch 14 is given more desirable support force.

Therefore, in the sock 10, the three arch structures of the soles function normally around the inner vertical arch B, and the horizontal arch A, inner vertical arch B and outer vertical arch shown in FIG. It will be able to more effectively support the three arch structures of Arch C.

[0029] In the sock 10 of this embodiment shown in Fig. 1, Fig. 2, Fig. 3, etc., the knitted fabric structure of the instep portion 12 is a flat knitted portion and a mesh (watermark) [2 X 2 mesh] portion. For example, flat knitting or pile knitting may be used, but flat knitting, mesh knitting, pile knitting, knitting, and other knitting may be combined as appropriate. You may make it do. That is, the knitting method for imparting stretchability to the knitted fabric structure in the low support region of the instep portion 12 can be variously changed.

Further, the knitted fabric yarn and weave of the arch portion 14 is knitted with a flat knitted portion and, for example, a second float (floating) portion by float knitting, and the knitted fabric structure of the foot side surface portion 16 is flat knitted. It is preferable to be knitted with a part and a mesh (watermark) part [1 X 1 mesh], but these knitted fabric structures are not limited, depending on the desired pressure applied to the support area, The knitted fabric structure can be changed as appropriate.

[0030] In the above-described embodiment, the material of the knitting yarn is not particularly limited. The surface yarn is not limited to cotton yarn, silk acrylic yarn, hemp yarn, cotton acrylic mixed yarn, wool yarn, hair acrylic. These yarns can be used for socks such as blended yarn, silk yarn, hemp acrylic blended yarn, and nylon yarn, and the cotton number can also be used as the yarn number corresponding to the desired appropriate characteristics. The back yarn is a yarn that can be used for socks such as nylon yarn, polyester yarn, core yarn, polyurethane cover yarn, etc. Denier can also be used that corresponds to denier that meets the desired characteristics. Further, the elastic yarn is not limited to rubber yarn, and various other elastic yarns having desired elasticity can be used.
