Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shoe lining used as a lining material inside a shoe body made of a resin such as a synthetic resin or a rubber-based resin. The present invention also relates to a shoe in which the shoe lining is lined with a shoe body and a method for manufacturing the shoe.

[0002]

2. Description of the Related Art Conventionally, inside boots made of rubber resin or the like, in order to improve tactile sensation and slipperiness,
Alternatively, the lining is lined to improve heat retention. As this lining, any material can be used as long as it can exhibit desired characteristics. In general, a bag-shaped weft knitted fabric is often used. The reason for this is mainly to rationalize the method of manufacturing boots, as described in detail below.

[0003] A general method of manufacturing boots made of rubber-based resin or the like will be described below with reference to FIG. First, a male shoe mold 10 imitating a shape from a human calf to a toe is prepared. Male 1 for this shoe
A lining 11 which is a lining material is mounted on the surface of No. Further, a female shoe mold 12 having a shape substantially matching and larger than the shape of the male shoe mold 10 is fitted to the male shoe mold 10. A molten resin 13 in which a rubber-based resin or the like is in a molten state is injected into a gap between the male mold 10 and the female mold 12. Thereafter, when the molten resin 13 is solidified by means such as crosslinking or cooling, a boots main body is formed. Further, since the molten resin 13 has slightly penetrated into the lining 11, the lining 11 and the boots main body are tightly integrated by solidification of the molten resin 13. The boots are manufactured as described above.

In such a manufacturing method, the lining 11, which is a lining material, is mounted on the male mold for shoes 10. When the lining 11 is wrinkled or sagged at the time of mounting, the following method is used. Disadvantages arise. That is, the wrinkle or the slack portion of the lining 11 may come into contact with the inner surface of the female shoe mold 12, and in such a case, the wrinkle or the slack portion may be exposed on the surface of the shoe body. For this reason, as the lining 11, a material having excellent elasticity and excellent fit to the male mold 12 for shoes is adopted. That is, male mold 1 for shoes
Since 0 is imitating a human foot, the lining 11
It is like a sock. Therefore, it is reasonable to use a bag-shaped weft knitted fabric like the sock as the lining 11. In particular, a tubular circular knitted fabric knitted by a sock knitting machine is sewn at one end into a bag shape, which can be easily manufactured and is most rational.

[0005]

However, even in the case of a bag-shaped weft knitted fabric such as a sock, wrinkles or sagging may occur in the ankle part 16 because the heel part 15 has a large extension. Was. The occurrence of such a phenomenon can be understood from the fact that we often experience wearing socks. Therefore, an object of the present invention is to provide a shoe lining made of a bag-like weft knitted fabric, which is less likely to cause wrinkles and sagging in the ankle part 16.

Further, the bottom of a cylindrical circular knitted fabric (corresponding to the sole) is sewn at the end to form a bag.
When attached to zero, the sewn portion only needs to be located at the sole of the foot, but depending on the state of extension, a part of the sewn portion sometimes goes around to the vicinity of the toe (toe side). A part of the sewn portion that has wrapped around the toe vicinity exists as a slack. Accordingly, an object of the present invention is to provide a shoe lining made of a bag-shaped weft knitted fabric, which can prevent the sewn portion from sagging around the toe vicinity.

[0007]

The present invention employs the following means in order to prevent wrinkles and sagging in an ankle part 16 of a shoe lining made of a bag-shaped weft knitted fabric. That is, the present invention relates to a bag-like lining for lining a shoe main body, wherein the bag-like lining is knitted with a weft knitting structure, and in a weft knitted fabric portion including a heel portion, a supply of a portion near a heel portion is provided. The present invention relates to a shoe lining characterized in that the yarn amount is knitted in the same course so as to be larger than the yarn supply amount of other parts.

The present invention employs the following means in order to prevent the sewn portion near the toe from sneaking into the vicinity of the toe. That is, the present invention relates to a bag-like lining for lining a shoe body, the bag-like lining is knitted in a weft knitting structure, and has a sewing portion near the toe to make the lining into a bag shape. In the weft knitted fabric portion including the toe vicinity portion, the knitting is performed by increasing the yarn supply amount in the toe vicinity region to be larger than the other region in the same course. It is about lining.

The present invention also relates to a shoe in which such a shoe lining is lined with a shoe main body, and to a method of manufacturing a shoe using such a shoe lining.

[0010] The shoe lining according to the present invention is knitted in a weft knitting structure. As the weft knitting structure, any conventionally known structure can be adopted. Specifically, tack knitting, flat knitting, rubber knitting, pearl knitting, faux knitting, and the like can be adopted. The knitting means is often knitted by a circular knitting machine such as a sock knitting machine, but may be knitted by another knitting machine such as a flat knitting machine or a milling knitting machine.

The weft knitted shoe lining has a bag shape. The lining may be made into a bag shape by sewing using a weft knitted fabric. For example, in the case of a long cloth, the left and right ends may be sewn to form a tube, and then one end of the tube may be sewn to form a bag. Also, like a sock worn by a person, it may be knitted by a sock knitting machine, bend over and sew the toe to form a bag. However, in the present invention, it is particularly preferable that the knitting is performed only by knitting the tubular dough with a circular knitting machine such as a sock knitting machine (a tubular dough is obtained without going through the overcasting step). It is best to sew one end of the fabric into a bag. In addition, when sewing one end of the bag-shaped cloth, instead of sewing it in a tubular shape, as shown in FIG. 1 which is an example of a simplified side view of the shoe lining according to the present invention, the longitudinal length of the toe side is shown. It is preferable to sew along the cut edge after cutting so that the length is long and the longitudinal length of the heel side is short.

One characteristic feature of the present invention is that, in the weft knitted fabric portion including the heel portion of the bag-like lining thus obtained, the yarn supply amount in the vicinity of the heel portion can be controlled within the same course. The point is that the knitting is performed with a larger amount than the yarn supply amount of other parts. Here, the "weft knitted fabric portion including the heel portion" is an area of a predetermined size including the heel portion of the lining, and refers to a band-shaped area extending over the entire area in the course direction. Based on Figure 1,
A band-shaped area having a width indicated by 1 and extending over the entire area in the course direction, that is, an area indicated by hatching (however, 15
Including the area. ). In addition, the “region near the heel” is a part of the weft knitted fabric portion including the heel, and refers to an area near the heel. Based on FIG. 1, the area is indicated by 2, that is, the area indicated by the diagonally shaded area. The “other part” in the weft knitted fabric part including the heel part is an area excluding the part near the heel part and the heel part from the weft knitted fabric part including the heel part. FIG.
Is an area indicated by 3, that is, an area indicated by a hatched portion falling leftward.

The weft knitted fabric portion including the heel portion is knitted in tens to hundreds of courses and has a width indicated by 1. In each of the same courses, the portion 2 near the heel portion and other portions are provided. 3, or the heel part 2, the heel part 15, and the other part 3 are knitted. At this time, in the same course, the yarn supply amount in the region 2 near the heel is made larger than the yarn supply amount in the other regions 3. Specifically, the knitting is performed by increasing the vertical movement width of the knitting needle when knitting the region 2 near the heel than when knitting the other region 3. As a result, when knitting the region 2 near the heel, the amount of drawn in yarn increases, and as a result, the amount of supplied yarn increases. Therefore, the yarn length forming one loop of the weft knitting structure in the region 2 near the heel is longer than the yarn length forming one loop of the weft knitting structure in the other portion 3. For this reason, the heel portion vicinity part 2 has a higher elongation rate than the other parts 3.

The yarn supply amount in the heel portion 15 is arbitrary, and may be, for example, the same as the yarn supply amount in the region 2 near the heel portion. In the present invention, it is preferable that the yarn supply amount at the heel portion 15 is smaller than the yarn supply amount at the heel portion vicinity portion 2. Further, the yarn supply amount in the heel portion 15 is smaller than the yarn supply amount in the region 2 near the heel portion, but is most preferably larger than the yarn supply amount in the other portions 3. Thereby, the extension of the heel portion 15 is suppressed to some extent, and the heel portion 15 of the shoe lining is prevented from being too thin.

The portion 2 near the heel portion, the heel portion 15, and the other portion 3 are all knitted in a weft knitting structure, but may be any structure, and may be the same structure or different structures. . In the present invention, it is preferable that the knitting structure of the region 2 near the heel is a tack knitting structure, and the heel 1
Preferably, the knitting organization of No. 5 is a flat knitting organization. This is because the flat knitted structure has a tighter loop than the tack knitted structure, so that even if the thickness of the heel portion 15 of the shoe lining becomes thin, it is less likely to be torn by abrasion. At this time, the knitting structure of the other portions 3 is arbitrary, but is generally knitted with a tack knitting structure.

Another characteristic feature of the present invention is that, in the weft knitted fabric portion including the toe portion of the bag-like lining, the amount of yarn to be supplied to the toe portion in the vicinity of the toe is adjusted within the same course. The point is that it is knitted with more than the quantity. Here, the "weft knitted fabric portion including the toe vicinity portion" is a region of a predetermined size including the toe vicinity portion of the lining, and refers to a band-shaped region over the entire region in the course direction. Based on FIG. 1, it is a band-shaped area having a width indicated by 4 and extending over the entire area in the course direction, that is, an area indicated by hatching. The “near toe part” is a part of the weft knitted fabric part including the toe near part, and refers to an area near the toe. Based on FIG. 1, it is an area indicated by 5, that is, an area indicated by a hatched portion falling to the right. The toe vicinity part may or may not include the toe. The “other part” in the weft knitted fabric part including the toe vicinity part is an area obtained by removing the toe knitted part from the weft knitted fabric part including the toe vicinity part. Based on FIG. 1, the area is indicated by 6, that is, the area indicated by the diagonally shaded area.

The weft knitted fabric portion including the near-toe portion is knitted in several to several tens of courses and has a width indicated by 4. In each of the same courses, the near-toe portion 5 and other portions 6 are provided. Will be organized. At this time, in the same course, the yarn supply amount in the toe vicinity part 5 is made larger than the yarn supply amount in the other parts 6. More specifically, as in the case described above, the knitting needle is moved up and down when knitting the near-toe portion 5 to be larger than when knitting the other portions 6. Thereby, when knitting the toe vicinity part 5, the amount of thread drawn in becomes large,
As a result, the yarn supply amount increases. Therefore, the yarn length forming one loop of the weft knitting structure in the toe vicinity portion 5 is:
It is longer than the yarn length forming one loop of the weft knitting structure at the other portion 6. For this reason, the toe vicinity portion 5 has a higher elongation rate than the other portions 6. In addition,
Each of the toe vicinity portion 5 and the other portion 6 is knitted with a weft knitting structure, but may be any structure, and may be the same structure or a different structure.

The shoe lining according to the present invention may have any one of the above-mentioned two characteristic items, or may have both of them. And such a shoe lining is used as a lining material of a shoe main body, and a shoe is obtained. Generally, shoes are preferably boots, but may be semi-boots or boots.

As a method for manufacturing shoes using the shoe lining according to the present invention, for example, the following manufacturing method can be mentioned. That is, after the above-mentioned shoe lining according to the present invention is attached to the surface of the foot-shaped shoe mold, the foot-shaped shoe mold is fitted to the male mold, and the female mold and the male mold are fitted. A method of injecting a molten resin between the mold and the mold, thereafter solidifying the molten resin to form a shoe body, and integrating the shoe body and the shoe lining. . The male mold for a foot-shaped shoe is a mold having a shape imitating the shape of a human foot. For example, when manufacturing boots, a mold having a shape imitating a shape from a human calf to a toe ( (The type shown by reference numeral 10 in FIG. 3). This male mold 10 for shoes is
Generally, it is made of metal (mold). Then, the shoe lining 11 according to the present invention is mounted on the surface of the male shoe mold 10. Specifically, the male shoe mold 10 may be fitted with the shoe lining 11. Further, a female shoe mold 12 having a shape substantially matching and larger than the shape of the male shoe mold 10 is fitted to the male shoe mold 10. That is, as shown in FIG. 3, the female shoe mold 12 is fitted with a slight gap between the inner surface of the female shoe mold 12 and the shoe lining 11. Then, a molten resin 13 in which a rubber-based resin or the like is melted is poured into the gap, and the molten resin 13 is solidified by means such as crosslinking or cooling to form a shoe body. As described above, a shoe in which the shoe main body and the shoe lining 11 are tightly integrated with each other is obtained.

[0024]

In the shoe lining according to the first aspect of the present invention, in the weft knitted fabric portion including the heel portion, the portion near the heel portion has a higher elongation than the other portions. Therefore, when the shoe lining is attached to the male shoe mold, the portion near the heel is well extended and follows the protrusion of the heel well. For this reason, wrinkles and sagging are less likely to occur in the shoe lining in other parts, particularly in the ankle part.

In the shoe lining according to the second aspect of the present invention, in the shoe lining according to the first aspect of the present invention, the heel portion has a smaller elongation rate than the portion near the heel portion. Therefore, when this shoe lining is attached to a male shoe shoe, the heel portion is stretched well, but the heel portion is less elongated. Therefore, the thickness of the heel portion of the shoe lining is less likely to be thinner than the portion near the heel portion.

The shoe lining according to the third aspect of the present invention is the shoe lining according to the second aspect of the present invention, wherein the knitting structure of the heel portion is a flat knitting structure. The loops (stitches) are in a state of being clogged as compared with the part. Therefore, the thickness of the heel portion of the shoe lining is less likely to be thinner than the portion near the heel portion.

In the shoe lining according to the fourth aspect of the present invention, in the weft knitted fabric portion including the portion near the toe, the portion near the toe has a higher elongation than the other portions. Therefore, when the shoe lining is attached to the male shoe mold, even if the sewn portion of the shoe lining wraps around the toe and becomes slack, this portion of the shoe lining is stretched downward to extend the vicinity of the toe so that the slack is attached to the sole of the foot. Can be moved. As a result, the shoe lining is less likely to sag at the toes.

The shoe lining according to the fifth aspect of the present invention is a combination of the shoe lining according to the fourth aspect of the present invention and the invention of any one of the first to third aspects. Is an effect of the above.

In the shoe according to the sixth aspect and the method for manufacturing the shoe according to the seventh aspect, the shoe lining according to each of the first to fifth aspects is used. The sagging hardly occurs, and the lining is hardly exposed on the surface of the shoe body.

[0030]

Thus, according to the present invention, shoes can be manufactured while preventing wrinkles and sagging of the shoe lining, so that wrinkles and sagging cause the lining on the surface of the shoe body. Exposure can be prevented, and an effect that a shoe with excellent appearance can be obtained rationally can be obtained. Also, if the heel is not thinned by changing the amount of yarn supplied and the knitting structure of the heel of the lining for shoes, the lining of the heel is not easily torn even if the shoes are worn repeatedly, This has the effect of extending the life.
