Description

  The present invention relates to a sock that is obtained from a tubular knitted fabric knitted with a circular knitting and is in a wearing state fitted to legs and feet. The socks include all socks such as socks, pantyhose, and tights.

  Socks that are required to fit on the foot and leg surfaces in the wearing state, such as socks and pantyhose, are first knitted as a cylindrical knitted fabric by circular knitting, and partly cut and sewn as necessary, Products that are finished as products are common. The socks obtained from the tubular knitted fabric can be stretched seamlessly in the circumferential direction, and can easily realize a state in which the socks are fitted to the corresponding parts of the lower limbs. As a function addition in such a sock product, a knitting structure such as plain knitting and tack knitting and partial density change are given to generate a greater pressing force and tightening force at other places than other parts, Many proposals have been made to provide functions such as correction and blood circulation promotion (prevention of swelling and reduction of fatigue). Among these conventional socks, there is one described in Japanese Patent Application Laid-Open No. 11-43805 as an example of pantyhose that can promote blood circulation in a worn state.

  In this conventional pantyhose, a knitted fabric forming a leg portion is provided with a portion knitted with two or more different stitch lengths in the same course to cause a pressure difference. By being distributed, an appropriate pressure stimulation force is given to each position of each part of the leg, and the effect of improving blood circulation of the entire leg is generated.

In addition, as another conventional sock, an example of a high sock knitted with a different knitting structure for each of a plurality of leg regions is described in Japanese Patent Laid-Open No. 2002-13005.
In the conventional high socks, the front shin part of the leg portion made of a substantially cylindrical body is made of a high pressure knitting structure, while the back calf part of the leg part is made of a low pressure knitting structure. It has a medium-pressure knitting structure between the knitting structures, and the above three-stage knitting structure gives a tightening pressure at the time of elongate wear to promote venous flow in the leg. .
Japanese Patent Laid-Open No. 11-43805 JP 2002-13005 A

  Conventional socks are configured as described above, and the legs that are designed to generate different pressures in the circumferential direction have been devised to obtain appropriate blood circulation promotion performance. Since the blood circulation promoting performance is not considered much structurally, the blood circulation promoting effect on the foot portion is not satisfactory because the blood circulation promoting performance is not satisfactory as a whole sock.

  The present invention has been made to solve the above-mentioned problems, and a plurality of regions having different pressure-applied states are appropriately arranged in the socks and feet, and appropriate compression stimulation according to the leg and foot portions is applied in the worn state. An object of the present invention is to provide a sock capable of providing a strong blood circulation promoting effect over the entire region where the sock is worn.

The sock according to the present invention is a sock obtained by subjecting a tubular knitted fabric knitted as a whole to a circular knitting as it is or by partially cutting and sewing, so that the first pressure is generated on the rear side of the leg portion. A first knitting structure is disposed, and a second knitting structure that generates a second pressure that is weaker than the first pressure is disposed in a region from the front surface side of the leg portion to the upper surface side of the foot portion, A sole knitting structure that generates a pressure equal to or higher than the first pressure is disposed at the arch portion of the foot part, and further , an intermediate portion of the leg part between the first knitting structure and the second knitting structure , and a foot an intermediate portion between the second knitted tissue and sole stitch parts, the first and third knitted tissue is arranged Rukoto cause at fixing pressure becomes the intermediate value to the second wearing pressure In addition, each knitting structure of the heel part and the toe part is a knitting structure that generates a weaker pressure than the second pressure, Arrangement of tissue is made of asymmetrical about socks centerline.

  As described above, in the present invention, the cylindrical knitted fabric forming the sock is knitted in a state in which a plurality of knitting structures having different structures are arranged in the sock circumferential direction, and a plurality of different pressures are applied to each knitting structure in the mounted state. To ensure a good fit for the foot and leg sock wearing parts, and appropriate pressure for each part with different properties, such as the muscular and other parts of the foot and leg. Can effectively impart pressure to both the legs and the legs to stimulate blood circulation in the entire region where the socks are attached, and more effectively exert effects such as fatigue reduction due to smooth blood flow.

In addition, each knitting structure of the heel part and the toe part is made into a knitting structure whose pressure is weaker than the second pressure, and by suppressing the pressure from the sock foot part on the heel and the toe having a large movement in the foot, An excellent feeling of wear is obtained without obstructing the movement, and the blood flow from the foot to the leg side can be smoothed by not tightening the transition part from the foot to the leg excessively and not disturbing the blood circulation. The blood circulation promoting effect associated with the strong wearing pressure is reliably exerted without decreasing.

  In addition, the sock according to the present invention has a structure in which the cylindrical knitted fabric is inserted as necessary, while a predetermined pressing yarn having a stronger elastic force than the raw yarn forming the knitted fabric is continued in the circumferential direction. At the same time, the insertion amount per rotation of the pressure-bonding yarn is reduced stepwise or gradually from the upper part to the lower part of the leg part.

  In this way, in the present invention, the pressure yarn is inserted in the sock circumferential direction to knit the knitted fabric, and the circumferential insertion amount of the pressure yarn is changed in the sock longitudinal direction, and the elastic force of the pressure yarn By supporting the expansion and contraction force of the knitted structure and ensuring sufficient pressure, and changing the insertion amount of the pressure yarn to cause a change in pressure in the sock circumferential direction as well as in the sock longitudinal direction, Alternatively, it is possible to more efficiently apply a compression stimulus to each part of the leg, and appropriately control the blood flow from the lower part of the leg to the upper side by changing the wearing pressure in the sock longitudinal direction, thereby further enhancing the blood circulation promoting effect.

In addition, the sock according to the present invention is inserted so that the pressure-applying thread is gradually or gradually increased from the middle part of the foot toward the toe side as needed.
As described above, in the present invention, by inserting the circumferential insertion amount of the pressure-applying thread in the sock foot portion so as to be directed toward the toe, and causing the change in the contact pressure in the sock longitudinal direction also in the foot portion, The compression force from the socks to each part of the foot can be applied more efficiently by the elastic force of the thread for pressing, and the blood flow promoting effect can be further enhanced by appropriately controlling the blood flow from the middle part of the foot to the toe side.

Further, the sock according to the present invention is configured such that a plurality of types of yarns having different properties are selectively inserted according to the insertion position in the longitudinal direction of the sock as the pressure yarn.
As described above, in the present invention, the sock longitudinal direction is used by changing the type of the pressure thread, and a large change in pressure is caused in the sock longitudinal direction separately from the change in the insertion amount of the pressure thread. Can be applied more efficiently to the feet or legs, leading to the promotion of blood circulation, and the appropriate strength of the socks by placing a suitable material thread for the position of the socks It can be.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS. In the present embodiment, an example of socks will be described. FIG. 1 is a front side perspective view of a sock according to the present embodiment, and FIG. 2 is a rear perspective view of the sock according to the present embodiment.

  In each of the drawings, the sock 1 according to the present embodiment has a configuration in which a portion corresponding to the heel and the toe is sewn in a tubular knitted fabric knitted by circular knitting so as to have a sock shape. . The shape of the sock itself is a known shape and structure that covers a portion from the foot to the shin part, and detailed description thereof is omitted.

  The sock 1 is provided with a strong pressure portion 11 as the first knitting structure that generates a first wearing pressure on the rear surface side of the leg portion 1a, and the front surface side of the leg portion 1a and the upper surface side of the foot portion 1b. A weak pressure portion 12 serving as the second knitting structure that generates a second pressure that is weaker than the first pressure is disposed on the arch portion of the foot 1b. A high high pressure portion 13 is disposed as the sole knitting structure for generating pressure, and further, an intermediate portion between the high pressure portion 11 and the low pressure portion 12 of the leg portion 1a and the low pressure portion 12 and the high high pressure portion 13 of the foot portion 1b. The intermediate pressure portion 14 serving as the third knitting structure that generates a predetermined pressure that is an intermediate value with respect to the first and second pressures is disposed at the intermediate portion. The arrangement state of each knitting structure is asymmetrical with respect to the center line of the sock in accordance with the shape of the foot and leg to be worn.

  In addition, the sock 1 has a configuration in which a predetermined range from the end of one opening portion in the leg portion is knitted as a rubber band 15 in which a rubber thread is inserted with a stretchable and easy-to-fit knitting. . On the other hand, the foot portion 1b of the sock 1 has a configuration in which the knitted structure in a predetermined range of the toe portion and the heel portion is an ultra-low pressure portion 16 having a lower pressure than the weak pressure portion 12 although having excellent stretchability. is there. Then, like the known socks, the toe portion is formed by sewing the other opening edge portion of the original tubular knitted fabric, and the heel portion is partially processed by sewing the intermediate portion of the tubular knitted fabric, and the Y heel. It is the structure formed in the shape.

  The base yarn of any part of these socks is only cotton or nylon, or a blend of these, or a blend of nylon and acrylic, silk, rayon, or wool. The fabric is knitted as a stretchable knitted fabric with raw yarn, and has a strength and breathability. The thickness of the raw yarn is 45 to 1680 dtex.

  In addition, socks knitted fabrics have an elastic force stronger than the original yarn and are excellent in stretchability over almost the entire sock knitted fabric in order to increase the stretch force and efficiently apply pressure, DCY, latex, spandex bear, etc. Are inserted into the sock circumferential direction continuously, and the insertion amount (length) per circumference of the sock circumferential direction is stepwise or gradually from the upper part to the lower part of the leg part 1a. The amount of insertion is reduced and the insertion amount is increased from the middle part of the foot toward the toe side, and since the change in the wearing pressure accompanying the change in the amount of insertion is given in the longitudinal direction of the sock, socks as well as known socks and pantyhose As an appropriate pressure force distribution in the longitudinal direction, the blood flow assisting function in the leg is provided.

  The strong pressure portion 11 is a knitting structure knitted with 2 × 1 American rib knitting, occupies a predetermined region at the center of the rear portion of the sock leg portion 1a corresponding to the rear side of the leg having a muscular portion, and the calf portion in a worn state It is the structure contact | abutted on the leg rear side including this. The knitted structure of the high pressure part 11 is knitted with a smaller stitch while using the same yarn as the other knitted structures of the low pressure part 12 and the intermediate pressure part 14, and is formed into a small stitch shape in the mounted state. This is a mechanism that generates a larger pressure than other parts (about 18 to 32 kPa). Moreover, the strong pressure part 11 can hold | maintain the position in the original wearing state arrange | positioned at the leg back side, bending-following with respect to the exercise | movement of a leg and a leg based on the elasticity.

  The weak pressure part 12 is a knitting structure knitted with 1 × 1 (2 × 2) mesh knitting (non-run knitting) and corresponds to the front part of the leg where the bones of the leg (tibia and ribs) are concentrated. It occupies a region from the front surface side of the sock leg portion 1a to the upper surface side of the foot portion 1b, and abuts from the front side of the leg including the shin portion to the upper surface of the foot in the mounted state. The knitting structure of the weak pressure portion 12 is knitted with a degree larger than that of the strong pressure portion 11 and the intermediate pressure portion 14, and has a larger stitch shape so that the knitting structure is more worn than the other portions of the sock leg portion 1a. This is a mechanism that produces the smallest pressure (about 6 to 20 kPa). The weak pressure portion 12 is set to have a width that is about one third of the outer circumference of the foot, but is stretched to occupy about half of the outer circumference of the foot because it is a knitted structure that stretches more easily than the surroundings when worn. The weak pressure portion 12 is arranged from the front surface of the leg to the upper surface of the foot while closely contacting the leg and the foot as a knitted structure having excellent stretchability and following the movement of the foot and the leg by bending and changing, similarly to the strong pressure portion 11. The position in the initial wearing state can be maintained.

  The high-strength portion 13 is a knitted structure knitted with 3 × 1 American rib knitting, and occupies a predetermined range at the center of the lower surface of the sock foot portion 1b corresponding to the arch on the lower surface of the foot, and abuts on the arch in the mounted state. It is. The knitted structure of the high-pressure part 13 is knitted with a smaller degree than the case of the strong-pressure part 11, and a strong elastic recovery force at the time of expansion / contraction accompanied by a small stitch shape causes a larger pressure than the strong-pressure part 11 in the mounted state. This is a mechanism that strongly presses the arch while maintaining the position in the initial state of placement placed along the arch of the foot (about 24 to 38 kPa).

  The intermediate pressure part 14 is a knitting structure knitted with 1 × 1 American rib knitting, and is an intermediate region between the high pressure part 11 and the low pressure part 12 of the leg part 1a and a low pressure part of the foot part 1b. 12 occupies an intermediate region between the high-pressure portion 13 and the high-pressure portion 13. The knitting structure of the intermediate pressure part 14 is knitted at the intermediate degree in each case of the weak pressure part 12 and the strong pressure part 11 at the time of knitting, and the intermediate pressure between the weak pressure part 12 and the strong pressure part 11 is just knitted. It is a mechanism that creates a stitch shape (about 12-26 kPa), and as with other parts of socks, it is a knitted fabric with excellent stretchability, while flexing and following the bending and stretching of the legs, while following the legs and feet The position in the initial wearing state arranged in the part can be maintained.

  The ultra-low pressure portion 16 forming the toe portion and the heel portion is a knitting structure corresponding to the toe portion and the heel portion, and is knitted with a plain knitting and has excellent stretchability, but does not cause pressure or fabric tension. It is the structure made into the state (about 0-12 kPa) which only the very weak contact pressure accompanying with occurs.

  Next, the usage state of the sock of this embodiment based on the said structure is demonstrated. The user passes his / her legs and legs through the sock 1, pulls the upper rubber band 15 up to the upper side of the shin of the leg, the weak pressure part 12 on the front side on the front side of the shin part, and the strong pressure part 11 on the rear side is just a calf. If each part is closely aligned with the surface of the corresponding part of the foot and leg, for example, the high high pressure part 13 is positioned on the arch of the sole of the foot. In this wearing state, since the weak pressure part 12 is a knitted structure weaker than other parts, it extends from about one-third of the outer circumference of the foot in the non-wearing state and occupies about half of the outer circumference of the foot.

  In this wearing state, each part of the sock 1 has sufficient elasticity, and can be supported by reliably covering the lower side from the shin part. Further, the rubber band portion 15 is in close contact with the leg with an appropriate tightening force, thereby preventing displacement from the mounting site. And the low pressure part 12 located in the front part of socks 1 will be in the state which adhered moderately from the front along the right-and-left side part from the front part of the shin part of the leg, and the strong pressure part 11 of the back side is just along the calf part. It comes into close contact with strong wearing pressure and gives a pressure stimulus to the calf from the back side.

  In this way, in the worn state, the weak pressure part 12, the strong pressure part 11, and the intermediate pressure part 14 give a pressing force to the legs in close contact with predetermined wearing pressures different in the sock circumferential direction, and there is no excessive tightening. The blood flow promoting effect by an appropriate compression stimulus can increase the blood flow at the wearing site, thereby reducing swelling and fatigue. Further, each part of the sock 1 can appropriately press the respective parts of the leg to give a correction effect to the leg.

  Also, in the foot part, the ultra-low pressure part 16 that forms the toe part and the heel part appropriately covers the corresponding part by expansion and contraction, while the weak pressure part 12 and the intermediate pressure part 14 are in close contact with each part of the foot, and the high-pressure part 13 is also in a state of being in close contact with the arch portion of the sole. In the wearing state, in the toes and heels with large movements, the ultra-low pressure part 16 is arranged to suppress the wearing pressure so as not to disturb the movement and blood circulation, while the low pressure part 12, the intermediate pressure part 14, In addition, the high high pressure portion 13 applies a pressing force to each foot portion in the close contact state with different predetermined contact pressures in the sock circumferential direction, and the high high pressure portion 13 that generates the strongest contact pressure is applied to the surface of the arch in the close contact state. While applying compression to the upper surface of the foot, the pressure decreases to the upper side of the foot, so that there is no excessive tightening. The blood circulation promotion effect is given to the whole part.

  And each part of the sock 1 including the strong pressure part 11 and the weak pressure part 12 does not greatly deviate from the shin part, calf part, and leg of the leg even when the exerciser moves the legs and legs of the wearer greatly. In addition, it is possible to maintain the pressure stimulation application state for the feet and legs at all times, maintain the blood circulation promotion performance, and not change the wearing feeling.

  As described above, in the sock according to the present embodiment, the high pressure part 11, the low pressure part 12, the high pressure part 13, and the intermediate pressure part 14 having different knitted structure are knitted and mounted in the sock circumferential direction. Since a plurality of different pressures are generated in the circumferential direction of the leg portion 1a and the foot portion 1b in the state, the foot and the leg of the leg and the leg are secured while maintaining a state of providing an excellent fit to the foot and leg sock wearing portion. Appropriate pressure can be applied to each part with different properties, such as muscular parts and parts that do not, and the legs and legs can be efficiently compressed to stimulate blood circulation throughout the sock-mounted part, resulting in smooth blood flow Effects such as fatigue reduction can be remarkably exhibited.

It is a wearing state front side perspective view of the sock which concerns on one embodiment of this invention. It is a rear surface side perspective view of the wearing state of the sock which concerns on one embodiment of this invention.
